    Diminished sexual functioning among individuals dependent upon alcohol has been assessed. Ninety-seven male patients entered the study, all inpatients as the unit for treatment of alcoholism and drug addiction (Villa 6) in Porirua Hospital, Porirua. The sexual ability of these patients before the development of alcoholism was also rated for the same items and this rating was used as a control. Of the 97 patients, 69 (71 percent) suffered from sexual dysfunction for a period more than 12 months prior to admission to hospital. The disturbances noted were diminished sexual desire (58 percent of patients), erectile impotence (16 percent), premature ejaculation (4 percent), ejaculatory in competence (22 percent). A high proportion of the alcoholics showed signs of sexual deviation-19 percent having performed sexual crimes and a further 28 percent having repeated thought of sexual crimes. The possible causes of alcohol induced sexual dysfunction are discussed.

    Alcohol use and sexual behavior are important risk behaviors in adolescent development, and combining the two is common. The reasoned action approach (RAA) is used to predict adolescents' intention to combine alcohol use and sexual behavior based on exposure to alcohol and sex combinations in popular entertainment media. We conducted a content analysis of mainstream (n = 29) and Black-oriented movies (n = 34) from 2014 and 2013-2014, respectively, and 56 television shows (2014-2015 season). Content analysis ratings featuring character portrayals of both alcohol and sex within the same five-minute segment were used to create exposure measures that were linked to online survey data collected from 1,990 adolescents ages 14 to 17 years old (50.3% Black, 49.7% White; 48.1% female). Structural equation modeling (SEM) and group analysis by race were used to test whether attitudes, norms, and perceived behavioral control mediated the effects of media exposure on intention to combine alcohol and sex. Results suggest that for both White and Black adolescents, exposure to media portrayals of alcohol and sex combinations is positively associated with adolescents' attitudes and norms. These relationships were stronger among White adolescents. Intention was predicted by attitude, norms, and control, but only the attitude-intention relationship was different by race group (stronger for Whites).

    The prevalence of alcohol-related regretted sex in college students warrants a better understanding of the characteristics of students who report such experiences. Therefore, the present study examined correlates of regretted sexual experiences involving alcohol use among 2 specific high-risk college student samples: students mandated to alcohol intervention (n = 522) and volunteer 1st-year students transitioning to college (n = 481). Results indicated that alcohol-related regretted sex occurred at similar rates in mandated and volunteer students, with approximately 25% of the students reporting at least 1 occurrence in the past month. Women were more likely to report alcohol-related regretted sex compared with men. The belief that alcohol use would result in "liquid courage" was associated with alcohol-related regretted sex among college students, even after accounting for greater alcohol use and problem alcohol use behaviors. These findings have significant implications for intervention efforts and future research.

    Drinking alcohol before sex increases the likelihood of engaging in unprotected intercourse, having multiple sexual partners and becoming infected with sexually transmitted infections. Borderline personality disorder (BPD), a complex psychiatric disorder characterised by pervasive instability in emotional regulation, self-image, interpersonal relationships and impulse control, is associated with substance use disorders and sexual risk behaviours. However, no study has examined the relationship between BPD and drinking alcohol before sex in the USA. This study examined the association between BPD and regularly drinking before sex in a nationally representative adult sample. Participants were 17 491 sexually active drinkers from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Logistic regression models estimated effects of BPD diagnosis, specific borderline diagnostic criteria and BPD criterion count on the likelihood of regularly (mostly or always) drinking alcohol before sex, adjusted for controls. Borderline personality disorder diagnosis doubled the odds of regularly drinking before sex [adjusted odds ratio (AOR) = 2.26; confidence interval (CI) = 1.63, 3.14]. Of nine diagnostic criteria, impulsivity in areas that are self-damaging remained a significant predictor of regularly drinking before sex (AOR = 1.82; CI = 1.42, 2.35). The odds of regularly drinking before sex increased by 20% for each endorsed criterion (AOR = 1.20; CI = 1.14, 1.27) DISCUSSION AND CONCLUSIONS: This is the first study to examine the relationship between BPD and regularly drinking alcohol before sex in the USA. Substance misuse treatment should assess regularly drinking before sex, particularly among patients with BPD, and BPD treatment should assess risk at the intersection of impulsivity, sexual behaviour and substance use.

    Alcohol is frequently identified as a potential contributor to HIV-related sexual risk taking. Drawing on alcohol expectancy explanations for postdrinking behavior, the present study tested the hypothesis that adolescents who drink alcohol on a given occasion will be more likely to engage in sexual risk-taking behavior to the extent that they believe that alcohol disinhibits sexual behavior or promotes sexual risk taking. The combined effects of sex-related alcohol expectancies and alcohol use in sexual situations were investigated using interview data from a representative sample of 907 (476 male) sexually experienced adolescents (13 to 19 years) who had ever consumed alcohol. Regression analyses on a composite measure of risk taking revealed that for two of three intercourse occasions examined alcohol use was associated with greater risk taking primarily among respondents who expected alcohol to increase risky sexual behavior. The results lend support to expectancy theories of alcohol's effects on sexual risk taking and raise the possibility that providing overly simplistic warnings that "alcohol leads to risky sex" may paradoxically increase the likelihood that individuals will fail to act prudently when intoxicated. Preventive interventions might beneficially focus on weakening, rather than strengthening, individuals' expectancies with regard to the impact of alcohol on sexual behavior, so that self-protective behavior will be more likely to occur even during intoxication.

    Full Text Available Abstract Background The spread of HIV in sub-Saharan Africa is believed to be driven by unsafe sex, and identification of modifiable risk factors of the latter is needed for comprehensive HIV prevention programming in the region. Some previous studies suggest an association between alcohol abuse and unsafe sexual behaviour, such as multiple concurrent sexual partnerships and inconsistent condom use in sex with non-spousal non-cohabiting partners. However, most of these studies were conducted in developed countries and the few studies in Africa were conducted among well-defined social groups such as men attending beer halls or sexually transmitted infection clinics. We therefore examined the association between alcohol and extramarital sex (a sign of multiple concurrent sexual partnerships among men in a population-based survey in Cameroon; a low-income country in sub-Saharan Africa with a high rate of alcohol abuse and a generalised HIV epidemic. Methods We analyzed data from 2678 formally married or cohabiting men aged 15 to 59 years, who participated in the 2004 Cameroon Demographic and Health Survey, using a multivariate regression model. Results A quarter of the men (25.8% declared having taken alcohol before their last sexual intercourse and 21% indicated that the last sex was with a woman other than their wife or cohabiting partner. After controlling for possible confounding by other socio-demographic characteristics, alcohol use was significantly associated with having extramarital sex: adjusted odds ratio (OR 1.70, 95% confidence intervals (CI 1.40 to 2.05. Older age (30–44 years: OR 3.06, 95%CI 2.16–4.27 and 45–59 years: OR 4.10, 95%CI 2.16–4.27, higher education (OR 1.25, 95%CI 1.10–1.45, and wealth (OR 1.71, 95%CI 1.50–1.98 were also significantly associated with higher odds of having extramarital sex.

    Adolescents often show risk-taking behavior, including experimentation with alcohol. Previous studies have shown that advanced pubertal maturation is related to increased alcohol use in adolescents, even when controlling for age. Little is known about the underlying mechanisms of this relation between pubertal maturation and alcohol use. The goal of the present study was twofold. In Experiment 1, we investigated whether advanced pubertal maturation is associated with higher levels of alcohol use, when controlling for age. To this end, questionnaires on pubertal development and alcohol use were administered to a large sample of 797 Dutch adolescents (405 boys) aged 11-16 years. In Experiment 2, we explored whether sex steroids contribute to this relation between pubertal maturation and alcohol use by examining the association between salivary sex steroid levels and alcohol use in 168 adolescents (86 boys). It was found that, when controlling for age, advanced pubertal maturation is related to increased alcohol use in adolescent boys and girls. Controlling for age, higher testosterone and estradiol levels correlated with the onset of alcohol use in boys. In addition, higher estradiol levels were associated with a larger quantity of alcohol use in boys. Correlations between sex steroids and alcohol use were not significant in girls. These findings show that advanced pubertal maturation is related to advanced alcohol use, and that higher sex steroid levels could be one of the underlying mechanisms of this relation in boys. Sex steroids might promote alcohol use by stimulating brain regions implicated in reward processing.

    Introduction The differential associations of beer, wine, and spirit consumption on cardiovascular risk found in observational studies may be confounded by diet. We described and compared dietary intake and diet quality according to alcoholic beverage preference in European elderly. Methods From the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES), seven European cohorts were included, i.e. four sub-cohorts from EPIC-Elderly, the SENECA Study, the Zutphen Elderly Study, and the Rotterdam Study. Harmonized data of 29,423 elderly participants from 14 European countries were analyzed. Baseline data on consumption of beer, wine, and spirits, and dietary intake were collected with questionnaires. Diet quality was assessed using the Healthy Diet Indicator (HDI). Intakes and scores across categories of alcoholic beverage preference (beer, wine, spirit, no preference, non-consumers) were adjusted for age, sex, socio-economic status, self-reported prevalent diseases, and lifestyle factors. Cohort-specific mean intakes and scores were calculated as well as weighted means combining all cohorts. Results In 5 of 7 cohorts, persons with a wine preference formed the largest group. After multivariate adjustment, persons with a wine preference tended to have a higher HDI score and intake of healthy foods in most cohorts, but differences were small. The weighted estimates of all cohorts combined revealed that non-consumers had the highest fruit and vegetable intake, followed by wine consumers. Non-consumers and persons with no specific preference had a higher HDI score, spirit consumers the lowest. However, overall diet quality as measured by HDI did not differ greatly across alcoholic beverage preference categories. Discussion This study using harmonized data from ~30,000 elderly from 14 European countries showed that, after multivariate adjustment, dietary habits and diet quality did not differ greatly according to alcoholic beverage

    Full Text Available Transactional sex is a risk factor for HIV infection. Alcohol use may increase the risk of transactional sex. No nationally-representative studies have examined the relationship between multiple dimensions of alcohol use and transactional sex in women in South Africa. The aim of the study was to examine the relationship between alcohol dependence, binge drinking and frequency of drinking in the past month and transactional sex in adult women in South Africa.A cross-sectional study using multi-stage, cluster sampling collected data from a nationally representative sample of 5,969 women aged 16-55 years in 2012. The analysis conducted for this paper was restricted to women reporting sexual activity in the past 12 months (n = 3,594. Transactional sex was defined as having received money/gifts in exchange for sex with any sex partner in the past year. Alcohol use measures included: alcohol dependence (≥2 positive responses to the CAGE questionnaire; binge drinking (≥4 drinks for women on one occasion; and drinking frequency in the previous month. Logistic regression models were built to test the hypotheses that each dimension of alcohol use was associated with transactional sex.About 6.3% (n = 225 of sexually active women reported transactional sex. Almost a third (30.6% of sexually active women had ever drunk alcohol, and 19.2% were current (past month drinkers. Among lifetime drinkers, 28.0% were alcohol dependent and 56.6% were binge drinkers. Alcohol dependent women were twice as likely to report transactional sex (AOR 2.0, 95% CI 1.1-4.3, p<0.05 than those not alcohol dependent. Binge drinkers were 3.1 times more likely to have had transactional sex (95% CI 1.5-6.6, p<0.01 than non-binge drinkers. There was no significant relationship between frequency of drinking in the past month and transactional sex.Alcohol dependency and binge drinking are significantly associated with transactional sex in South African women.

    Chronic intermittent alcohol (CIA) exposure produces altered motivational states characterized by anxiety and escalated alcohol consumption during withdrawal. The endocannabinoid (ECB) system contributes to these symptoms, and sex differences in alcohol dependence, as well as bidirectional interactions between ECBs and gonadal hormones have been documented. Thus, we evaluated sex differences in alcohol consumption, anxiety-like behavior, and ECB mRNA expression in the nucleus accumbens (NAc) of alcohol-dependent rats during acute withdrawal. Male rats exposed to six weeks of CIA showed escalated alcohol consumption during acute withdrawal and reductions in NAc N-acyl phosphatidylethanolamine phospholipase D (NAPEPLD), DAG lipase alpha (DAGLα), and monoacylglycerol lipase (MAGL) mRNA. Intact alcohol-dependent female rats also escalated their consumption, but notably, this effect was also present in non-dependent females. No differences in NAc ECB mRNA were observed between CIA- and air-exposed females during acute withdrawal. However, when these data were analyzed according to estrous stage, significant differences in NAPEPLD and MAGL mRNA expression emerged in the NAc of air-exposed control rats, which were absent in alcohol-dependent females. We subsequently measured alcohol consumption and NAc ECB mRNA in ovariectomized (OVX) females with or without estradiol (E2) replacement during withdrawal. Neither E2 nor CIA altered alcohol consumption in OVX females. However, E2 reduced both DAGLα and MAGL mRNA, suggesting that E2 may influence the biosynthesis and degradation of 2-arachidonoylglycerol (2-AG) in the NAc. Collectively, these studies indicate sexual dimorphism in alcohol consumption in non-dependent rats and suggest that E2-mediated alterations in NAc ECB mRNA expression during withdrawal may be a mechanism by which sex differences in alcohol dependence emerge.

    Alcohol use and abuse profoundly influences a variety of behaviors, including social interactions. In some cases, it erodes social relationships; in others, it facilitates sociality. Here, we show that voluntary alcohol consumption can inhibit male partner preference (PP) formation (a laboratory proxy for pair bonding) in socially monogamous prairie voles (Microtus ochrogaster). Conversely, female PP is not inhibited, and may be facilitated by alcohol. Behavior and neurochemical analysis suggests that the effects of alcohol on social bonding are mediated by neural mechanisms regulating pair bond formation and not alcohol's effects on mating, locomotor, or aggressive behaviors. Several neuropeptide systems involved in the regulation of social behavior (especially neuropeptide Y and corticotropin-releasing factor) are modulated by alcohol drinking during cohabitation. These findings provide the first evidence to our knowledge that alcohol has a direct impact on the neural systems involved in social bonding in a sex-specific manner, providing an opportunity to explore the mechanisms by which alcohol affects social relationships.

    Increasing evidence suggests that non-alcoholic fatty liver disease (NAFLD) and polycystic ovary syndrome (PCOS) are associated with obesity, insulin resistance, metabolic syndrome, cardiovascular disease, cirrhosis, and liver tumors. On these grounds, we have hypothesized that NAFLD and PCOS occur more frequently than expected by chance alone. We have tested this hypothesis by reviewing the clinical and biological evidence that supports a significant association between NAFLD and PCOS. PubMed was extensively searched for articles published through March 2015 using the keywords "nonalcoholic fatty liver disease" or "fatty liver" combined with "PCOS." Several cross-sectional and case-control studies have consistently demonstrated that the prevalence of NAFLD is remarkably increased in young women with PCOS, independent of overweight/obesity and other coexisting metabolic syndrome features, and that these women are more likely to have the more severe forms of NAFLD (non-alcoholic steatohepatitis, advanced fibrosis, and cirrhosis). Accumulating evidence suggests that NAFLD, especially its necro-inflammatory form, may exacerbate hepatic and systemic insulin resistance and releases multiple pro-inflammatory, pro-coagulant, and pro-fibrogenic mediators that may play important roles in the pathophysiology of PCOS. These findings call for more active and systematic search for NAFLD among women with PCOS. Conversely, gastroenterologists/hepatologists need to be aware of the presence of PCOS among female patients with NAFLD and compatible clinical features. Finally, all these patients should undergo regular follow-up not only for liver-related complications but also for cardio-metabolic diseases.

  5. Enhancing global control of alcohol to reduce unsafe sex and HIV in sub-Saharan Africa

    2009-11-01

    Full Text Available Abstract Sub-Saharan Africa carries a massive dual burden of HIV and alcohol disease, and these pandemics are inextricably linked. Physiological and behavioural research indicates that alcohol independently affects decision-making concerning sex, and skills for negotiating condoms and their correct use. More than 20 studies in Africa have reported higher occurrence of HIV among people with problem drinking; a finding strongly consistent across studies and similar among women and men. Conflation of HIV and alcohol disease in these setting is not surprising given patterns of heavy-episodic drinking and that drinking contexts are often coterminous with opportunities for sexual encounters. HIV and alcohol also share common ground with sexual violence. Both perpetrators and victims of sexual violence have a high likelihood of having drunk alcohol prior to the incident, as with most forms of violence and injury in sub-Saharan Africa. Reducing alcohol harms necessitates multi-level interventions and should be considered a key component of structural interventions to alleviate the burden of HIV and sexual violence. Brief interventions for people with problem drinking (an important component of primary health care, must incorporate specific discussion of links between alcohol and unsafe sex, and consequences thereof. Interventions to reduce alcohol harm among HIV-infected persons are also an important element in positive-prevention initiatives. Most importantly, implementation of known effective interventions could alleviate a large portion of the alcohol-attributable burden of disease, including its effects on unsafe sex, unintended pregnancy and HIV transmission.

    Only a minority of heavy drinking individuals develop alcoholic hepatitis (AH), for unclear reasons. We analyzed data from the Translational Research and Evolving Alcoholic Hepatitis Treatment cohort, consisting of subjects who drink heavily with normal results from liver tests (controls) and patients with AH. We examined risk factors for the development of AH including body mass index (BMI), drinking pattern and quantity, and sex. We compared data from 145 patients with AH and 124 controls based on BMI when they joined the cohort; groups were matched for sex and race. Drinking patterns were assessed using the timeline followback method, the Alcohol Use Disorders Identification Test, and the National Institute of Alcohol Abuse and Alcoholism 6-question survey. We performed univariable and multivariable analyses to assess the effects of these factors and their interaction in increasing the risk for AH. We also explored the association between PNPLA3 variants and AH. Cases with AH were older (47 vs 44 y; P = .03). For nearly all measures of quantity of alcohol consumed or frequency of binge drinking, controls drank more heavily than cases with AH. We did not find an association between BMI, sex, drinking patterns, and the presence of AH. Age and BMI were independent predictors for the severity of AH. When we analyzed cases and controls of European ancestry, the PNPLA3 single-nucleotide polymorphism rs738409 was associated with risk for AH (odds ratio, 1.89; P = .007). Compared with heavy drinkers without liver disease, subjects with AH consumed lower levels of alcohol and had less binge drinking, suggesting an increased sensitivity to the toxic effects of alcohol. The risk for AH may be associated with the PNPLA3 rs738409 polymorphism. Copyright © 2016 AGA Institute. Published by Elsevier Inc. All rights reserved.

  11. Social-Context Factors, Refusal Self-Efficacy, and Alcohol Use Among Female Sex Workers in China

    2014-01-01

    Excessive alcohol use is considered as a health risk behavior that may produce negative health outcomes. Examining predictors of alcohol use in a social or individual context can advance understanding of why people indulge in alcohol use. Our research on female sex workers (FSWs) examined associations among several social-context factors (alcohol use by family members, alcohol use by peers, and client-perpetrated pressure or violence), refusal self-efficacy, and alcohol use. Seven hundred FSW...

    Individuals who drink alcohol for the explicit motive of facilitating or enhancing sex may be more likely to engage in risky sexual behavior, including having sex under the influence of alcohol. However, efforts to assess sexual motives for drinking (SMDs) have been very limited to date. We examined the psychometric properties of a 5-item measure of SMDs in a sample of HIV-positive heavy drinking men who have sex with men. Findings provided excellent support for the scale's internal consistency and concurrent validity with a well-established measure of sexual alcohol expectancies (SAEs). Good discriminant validity was also established, as SMDs were correlated with other drinking motives but uniquely predicted the proportion of sex acts occurring under the influence of alcohol and other drugs, over and above other drinking motives and SAEs. SMDs were not significantly associated with unprotected anal intercourse. Adjusting for alcohol problem severity, higher SMDs were associated with lower willingness to consider changing drinking. Results suggest this measure of SMDs exhibits sound psychometric properties and may be useful in studies examining the association between alcohol use and sexual behavior. (PsycINFO Database Record

    The global literature suggests that female sex workers (FSWs) experience high rates of sexual violence perpetrated by their clients, especially when FSWs are under the influence of alcohol. However, such data are limited in China. The current study is aimed to fill in the literature gap by examining the association between alcohol use by FSWs and client-perpetrated sexual violence against FSWs in China. A total of 1022 FSWs were recruited through community outreach in Guangxi, China. Female sex workers completed a self-administered survey on their demographic information, alcohol use, and sexual violence perpetrated by clients. Multivariable regression was employed to assess the relationship between alcohol use and client-perpetrated sexual violence among FSWs while controlling for possible confounders. Results indicated that alcohol use was positively associated with the experience of sexual violence in both bivariate and multivariable analyses. Women who were at a higher risk level of alcohol use were more likely to experience sexual violence perpetrated by clients even after controlling confounders (e.g., demographics and alcohol-serving practice). Given the association between alcohol use and client-perpetrated sexual violence, preventing or reducing alcohol use among FSWs could be an effective strategy to protect these women from sexual violence perpetrated by their clients. Alternatively, psychological counseling and other support should be available to these women so they can reduce their alcohol use as a maladaptive coping strategy. We call for culturally appropriate alcohol use reduction components, incorporated with sexual violence reduction strategies including adaptive coping skills training as well as empowerment, and targeting both FSWs and their clients.

    This article presents data about the relationship between alcohol consumption prior to sex and unprotected sex and the prevalence of at least one sexually transmitted infection (STI) including HIV among socially marginalized men in three coastal Peruvians cities. During an epidemiological survey with 2,146 men, we assessed their STI prevalence, frequency of alcohol consumption prior to sex, unprotected sex and other sexual risk behaviors. The overall prevalence of at least one STI/HIV was 8.5 % (95 % CI 7.3–9.7), the prevalence of unprotected sex was 79.1 % (95 % CI 77.8–80.3) and alcohol consumption prior to sex with any of the last five sex partners in the previous 6 months was 68.9 % (95 % CI 66.9–70.9). Bivariate and multivariate analysis showed that alcohol consumption of participants or their partners prior to sex were associated with the prevalence of at least one STI, adjusted Prevalence Ratio (aPR) = 1.3 (95 % CI 1.01–1.68). Unprotected sex was significantly associated with alcohol consumption prior to sex when both partners used alcohol, aPR = 1.15 (95 % CI 1.10–1.20) or when either one of them used alcohol aPR = 1.14 (95 % CI 1.09–1.18). These findings concur with previous literature suggesting a relationship between alcohol consumption prior to sex and STI and HIV. These data improve our understanding of this relationship in this context and could be used to enhance STI and HIV prevention strategies for socially marginalized men in Peru. PMID:23054035

  16. Sex- and hormone-dependent alterations in alcohol withdrawal-induced anxiety and corticolimbic endocannabinoid signaling.

    Alcohol dependence is associated with anxiety during withdrawal. The endocannabinoid (ECB) system participates in the neuroendocrine and behavioral response to stress and changes in corticolimbic ECB signaling may contribute to alcohol withdrawal-induced anxiety. Moreover, symptoms of alcohol withdrawal differ between sexes and sexual dimorphism in withdrawal-induced ECB recruitment may be a contributing factor. Herein, we exposed intact male and female rats and ovariectomized (OVX) female rats with or without estradiol (E2) replacement to 6 weeks of chronic intermittent alcohol vapor and measured anxiety-like behavior, ECB content, and ECB-related mRNA in the basolateral amygdala (BLA) and ventromedial prefrontal cortex (vmPFC). Acute alcohol withdrawal increased anxiety-like behavior, produced widespread disturbances in ECB-related mRNA, and reduced anandamide (AEA) content in the BLA and 2-arachidonoylglycerol (2-AG) content in the vmPFC of male, but not female rats. Similar to males, alcohol-exposed OVX females showed reductions in Napepld mRNA in the BLA, decreased AEA content in the BLA and vmPFC, and reductions in all ECB-related genes measured in the vmPFC. Importantly, E2 replacement prevented withdrawal-induced alterations in ECB content (but not mRNA) in OVX females, and although alcohol-exposed OVX females failed to exhibit more anxiety compared to their respective control, chronic alcohol exposure abolished the anxiolytic properties of E2 in OVX rats. These data indicate that ovarian sex hormones (but not E2 alone) protect against withdrawal-induced alterations in corticolimbic ECB signaling but do not impart resilience to withdrawal-induced anxiety. Thus, the mechanisms implicated in the manifestation of alcohol withdrawal-induced anxiety are most likely sex-specific.

    We explored factors associated with alcohol use before or during sex among a sample of 10,861 men who have sex with men (MSM) in Asia who were recruited online for the study. Multinomial logistic regression analysis indicated that having sex under the influence of alcohol was associated with having multiple male partners, seeking partners primarily through gay bar/gym/dance party/friends, selling sex and using multiple drugs during the past 6 months, and unprotected anal sex. More efforts are needed to better assess alcohol use and misuse among MSM in Asia and understand contextual influences on alcohol use and HIV-related behaviors in order to implement culturally-specific interventions.

    This study investigated the relationship between alcoholics' personality characteristics [as indexed by the Eysenck Personality Questionnaire (EPQ)] and sex steroid levels. Three serum samples were drawn over a 90-min period in 58 inpatient male alcoholics (mean 33 days sober) and 33 non-alcoholic controls. The EPQ was administered at approximately the same point in the treatment process. Replicating previous work, we found alcoholics scored significantly higher on the Neuroticism and Psychoticism scales of the EPQ than controls. Alcoholics also had higher levels of estradiol and total testosterone than controls, which may be reflective of a biological rebound or characteristic premorbid levels. A significant positive correlation was found between testosterone and extroversion in controls, but not in alcoholics. Alcoholics showed a positive correlation between estradiol and neuroticism and a negative relationship between estradiol and extroversion. The results suggest that (a) 'normal' hormone-personality relationships are disrupted in male alcoholics, and b) personality and psychological changes consistent with the physical feminization syndrome may occur in male alcoholics.

    Full Text Available The HIV/AIDS epidemic among Chinese men who have sex with men (MSM has become a significant public health concern. Knowledge of alcohol consumption in this population is limited. In this study, 1,155 Chinese MSM were surveyed to assess alcohol use and its correlates. A meta-analysis was also performed to aggregate pooled prevalence of current alcohol use. MSM who were unmarried (aOR: 1.87; 95% CI: 1.29–2.71 or unemployed/retired (aOR: 2.77; 95% CI: 1.73–4.45 were more likely to drink alcohol more than once per week. MSM who consumed alcohol more than once per week were more likely to use drug (P<0.01, have sex with women (P<0.01, have unprotected insertive (P=0.04 or receptive (P=0.03 anal sex with men, have more than 10 lifetime male sex partners (P<0.01, predominantly practice insertive anal sex (P<0.01, and trade sex for money (P<0.01. Pooled overall alcohol use prevalence was 32%. Pooled prevalence for MSM who drank alcohol more than once per week and who drank alcohol before sex with male partners was 23%. Our findings provide the basis for further exploring the alcohol-HIV association and developing risk reduction interventions.

    Alcohol use is correlated with unprotected sex, which may place young men who have sex with men (YMSM) who use alcohol with sex at increased risk for contracting HIV. However, little is known about how this link develops. This study used qualitative interviews to explore how alcohol became associated with sex and sexual risk among YMSM. We purposively sampled 20 Black and 20 Latino YMSM (N = 40), ages 21 to 24, who used substances (alcohol, marijuana, and crystal methamphetamine) with sex. Interviews focused on participants' personal histories to trace how these associations developed for each individual. Drawing on sexual script, emotion regulation, and alcohol expectancy theories, analyses followed a modified grounded theory approach. Participants stated that alcohol enabled them to engage in sexual behaviors with men that they wanted to try, allowing them to be more "bold," overcome stigma about homosexuality, and feel increased comfort with their sexual desires and identities. The use of alcohol during sex was helpful to some of the participants but could also lead to sexual risk behaviors. Intervention programs seeking to reduce alcohol misuse and sexual risk should take into account how YMSM conceptualize associations between alcohol and sex. These programs may be more effective if they provide support for sexual identity exploration.

    Female sex workers' (FSWs') use of alcohol, a known disinhibitor to risk behaviour, has been largely understudied. Knowledge of how various sex work venues influence FSW's alcohol consumption before engaging in commercial sex is even rarer. Our analysis identifies those factors across three types of sex-work venues that predict alcohol use among FSWs prior to paid sexual intercourse with clients. Our data were collected through structured interviews with FSWs engaging in commercial sex in Senggigi Beach, Lombok Island in the eastern Indonesian province of West Nusa Tenggara. Employing a cross-sectional and multilevel design, three categories of venues where FSWs meet clients in Senggigi were sampled: (1) discotheques and bars (freelance), (2) brothels, and (3) recreational enterprises such as karaoke establishments and massage parlors. The sample consisted of 115 women "nested" within 16 sex work venues. The FSWs reported on 326 clients interactions. Results show that FSWs consumed alcohol before commercial sex with 157 (48%) of the 326 clients interactions. Alcohol use varied by differences in HIV policies and services offered at the sex work venue, the FSW's educational level and age, and client characteristics. Alcohol use is common prior to sexual intercourse among FSWs and their clients in Senggigi, and the venue where FSWs meet their clients influences the women's alcohol use. Freelancers were likelier to use alcohol than those who work at brothels and recreational enterprises. Given the recognized links between alcohol use prior to sex and high risk behaviour, HIV prevention programmes that discourage alcohol use should be introduced to both women who engage in commercial sex and also sex-work venue managers, owners, and clients.

    Prior studies with men who have sex with men have documented a strong association between substance use with sex and risk for acquisition of HIV. However, few studies have been conducted about gay male couples' use of substances with sex, despite the fact that between one third and two thirds of men who have sex with men acquire HIV from their relationship partners. The present study sought to (1) describe whether one or both partners in the male couple uses substances with sex-by substance type-within and/or outside of their relationship, and (2) assess whether differences exist in those who use substances with sex within and outside the relationship by the couples' HIV status. Dyadic data for this analysis were collected in the United States from a nation-wide cross-sectional Internet study about male couples' relationships and behaviors. Couple-level descriptive and comparative analyses were employed with 361 male couples. Except for alcohol, most couples did not use substances with sex. Of those who did, rates of who used it with sex and substance type within the relationship varied; most couples only had one partner who used substances with sex outside the relationship. Significantly higher proportions of concordantly HIV-negative and HIV-positive couples had both partners who used substances (all types) with sex within their relationship over discordant couples. Most couples had one partner who used outside the relationship; only marijuana and erectile dysfunction medication use with sex significantly differed by couples' HIV status. Findings indicate the need to conduct additional research for prevention development.

    Men who have sex with men (MSM) account for the largest proportion of new HIV infections in the United States. Alcohol may facilitate HIV transmission by increasing unprotected anal sex, but few studies have focused on transmission behaviors in HIV-positive MSM. This study explored daily associations between alcohol use and sexual behavior among heavy drinking HIV-positive MSM using a 30-day Timeline Followback interview. Results of generalized estimating equations indicated that greater alcohol consumption on a given day was associated with a linear increase in the odds of having unprotected anal sex with partners of any HIV status. However, the odds of reporting unprotected anal sex with HIV-negative or HIV-status unknown partners increased in a curvilinear fashion, occurring primarily at very heavy levels of use (12+ drinks). Results suggest that very heavy drinking increases the risk of engaging in sexual behavior that has the potential for transmitting HIV to other men.

    The relationship between transactional sex, HIV risk, and partner violence has been well documented in South Africa, but research has focused primarily on women and has not been conducted in high-risk social contexts. The aim of this study was to examine associations between transactional sex and HIV risk among women and men in alcohol-serving venues in Cape Town, South Africa. We surveyed 1,989 women and 2,468 men attending alcohol-serving venues in Cape Town, South Africa to assess transactional sex behavior (i.e., receiving money or goods in exchange for sex), alcohol and drug use, history of childhood abuse, current relationship violence, and sexual risk behaviors. Among both women and men, trading sex was related to higher alcohol use, greater likelihood of drug use, substance use in sexual contexts, and a greater likelihood of experiencing physical and sexual violence. Compared to other women, women who traded sex reported a greater proportion of condom-unprotected sex; this relationship was not found for men. Analyses showed that men were almost twice as more likely to report trading sex for items, including money or alcohol, than women (9.7 vs. 5.8 %). Overall, men who traded sex were similar to their female counterparts. Similar associations between trading sex and different risk behaviors were found among women and men with limited economic means and substance use problems. Future research should more closely study transactional sex in high-risk venues as it relates to violence and should examine men who trade sex as a potential bridge population between heterosexual women and men who have sex with men.

    Drinking to cope with negative affect is a drinking pattern that leads to problematic alcohol use both in college and after graduation. Despite theory and correlational evidence to this effect, establishing a link between stress and alcohol consumption among college students in the laboratory has yielded both a limited number of studies and, at times, inconsistent results. The present study attempts to resolve these issues through investigating the effects of an ecologically relevant stressor-ostracism-on alcohol consumption in a clinical laboratory setting. Social drinking college students (N = 40; 55% female) completed a 5-min game of Cyberball and were randomly assigned either to be included or excluded in the virtual ball-toss game. The amount (in ml) of beer consumed in a subsequent mock taste test served as our primary dependent variable, with breath alcohol concentration (BrAC) as a secondary dependent variable. Results indicated that excluded participants reported a trend toward an increase in negative affect from pre- to post-Cyberball, and endorsed significantly lower self-esteem, belonging, control, and belief in a meaningful existence compared to included participants. A significant Sex × Condition effect indicated that excluded women consumed less beer than both included women and excluded men, supported by a nonsignificant trend in BrAC. Men did not differ in their consumption of beer as a result of Cyberball condition. Implications of sex and social context on alcohol use are discussed, as well as ostracism as a method for investigating relationships between social stress and alcohol use.

    Deficiency of sex hormones and excessive alcohol consumption are factors that have been related to alterations in the pattern of bone mineralization and osteoporosis. The aim of this study was to evaluate possible alterations in the calcium/phosphorus (Ca/P) ratio in the femur of rats subjected to sex hormone deficiency and/or alcohol consumption. Methods. Female and male Wistar rats (n = 108) were divided into ovariectomized (Ovx), orchiectomized (Orx), or sham-operated groups and subdivided according to diet: alcoholic diet (20% alcohol solution), isocaloric diet, and ad libitum diet. The diets were administered for 8 weeks. The Ca/P ratio in the femur was analyzed by energy dispersive micro-X-ray spectrometer (μEDX). Results. Consumption of alcohol reduced the Ca/P ratio in both females and males. The isocaloric diet reduced the Ca/P ratio in females. In groups with the ad libitum diet, the deficiency of sex hormones did not change the Ca/P ratio in females or males. However, the combination of sex hormone deficiency and alcoholic diet presented the lowest values for the Ca/P ratio in both females and males. Conclusions. There was a reduced Ca/P ratio in the femur of rats that consumed alcohol, which was exacerbated when combined with a deficiency of sex hormones. PMID:27073396

    Female sex workers (FSWs) are the group at greatest risk for human immunodeficiency virus (HIV) infection in India. Women and girls trafficked (ie, forced or coerced) into sex work are thought to be at even greater risk because of high exposure to violence and unprotected sex, particularly during the early months of sex work, that is, at initiation. Surveys were completed with HIV-infected FSWs (n = 211) recruited from an HIV-related service organization in Mumbai, India. Approximately 2 in 5 participants (41.7%) reported being forced or coerced into sex work. During the first month in sex work, such FSWs had higher odds of sexual violence (adjusted odds ratio [AOR], 3.1; 95% confidence interval [CI], 1.6-6.1), ≥ 7 clients per day (AOR, 3.3; 1.8-6.1), no use of condoms (AOR, 3.8, 2.1-7.1), and frequent alcohol use (AOR, 1.9; 1.0-3.4) than HIV-infected FSWs not entering involuntarily. Those trafficked into sex work were also at higher odds for alcohol use at first sex work episode (AOR, 2.2; 95% CI, 1.2-4.0). These results suggest that having been trafficked into sex work is prevalent among this population and that such FSWs may face high levels of sexual violence, alcohol use, and exposure to HIV infection in the first month of sex work. Findings call into question harm reduction approaches to HIV prevention that rely primarily on FSW autonomy.

    In many countries, conflicting gradients in alcohol consumption and alcohol-associated mortality have been observed. To understand this 'alcohol harm paradox' we analysed the socio-economic gradient in alcohol-associated hospital admissions to test whether it was greater in conditions which were: (1) chronic (associated with long-term drinking) and partially alcohol-attributable, (2) chronic and wholly alcohol-attributable, (3) acute (associated with intoxication) and partially alcohol-attributable and (4) acute and wholly alcohol-attributable. Our aim was to clarify how (1) drinking patterns (e.g. intoxication linked to acute admissions or dependence linked to chronic conditions) and (2) non-alcohol causes (e.g. smoking and poor diet which are risks for partially alcohol-attributable conditions) contribute to the paradox. Regression analysis testing the modifying effects of condition-group (1-4 above) and sex on the relationship between area-based deprivation and admissions. England, April 2010-March 2013. A total of 9 239 629 English hospital admissions where a primary or secondary cause was one of 36 alcohol-associated conditions. Admissions by condition and deciles of Index of Multiple Deprivation (IMD). Socio-economic gradient measured as the relative index of inequality (RII, the slope of a linear regression of IMD on admissions adjusted for overall admission rate). Conditions were categorized by ICD-10 code. A socio-economic gradient in hospitalizations was seen for all conditions, except partially attributable chronic conditions. The gradient was significantly steeper for conditions which were wholly attributable to alcohol and for acute conditions than for conditions partially alcohol-attributable and for chronic conditions. Gradients were steeper for men than for women in cases of wholly alcohol attributable conditions. There is a socio-economic gradient in English hospital admission for most alcohol-associated conditions. The greatest inequalities are in

    In May 2014, Dr. Francis Collins, the director of U.S. National Institutes of Health (NIH), and Dr. Janine Clayton, the director of the U.S. National Institutes of Health Office of Research on Women's Health, published a commentary in the journal Nature announcing new policies to ensure that preclinical research funded by the NIH considers both males and females. While these policies are still developing, they have already generated great interest by the scientific community and triggered both criticism and applause. This review provides a description and interpretation of the NIH guidelines, and it traces the history that led to their implementation. As expected, this NIH initiative generated some anxiety in the scientific community. The use of female animals in the investigation of basic mechanisms is perceived to increase variability in the results, and the use of both sexes has been claimed to slow the pace of scientific discoveries and to increase the cost at a time characterized by declining research support. This review discusses issues related to the study of sex as a biological variable (SABV) in alcohol studies and provides examples of how researchers have successfully addressed some of them. A practical strategy is provided to include both sexes in biomedical research while maintaining control of the research direction. The inclusion of sex as an important biological variable in experimental design, analysis, and reporting of preclinical alcohol research is likely to lead to a better understanding of alcohol pharmacology and the development of alcohol use disorder, may promote drug discovery for new pharmacotherapies by increasing scientific rigor, and may provide clinical benefit to women's health. This review aims to promote the understanding of the NIH's SABV guidelines and to provide alcohol researchers with a theoretical and practical framework for working with both sexes in preclinical research.

    Full Text Available Objectives:  The recommended zolpidem starting dose was lowered in females (5mg vs 10mg since side effects were more frequent and severe than those of males; the mechanism underlying sex differences in pharmacokinetics (PK is unknown.  We hypothesized that such differences were caused by known sex-related variability in alcohol dehydrogenase (ADH expression. Methods:  Male, female, and castrated male rats were administered 2.6 mg/kg zolpidem, +/- disulfiram (ADH/ALDH pathway inhibitor to compare PK changes induced by sex and gonadal hormones.  PK analyses were conducted in rat plasma and rat brain. Key findings:  Sex differences in PK were evident: females had a higher CMAX (112.4 vs 68.1 ug/L and AUC (537.8 vs 231.8 hr*ug/L than uncastrated males.  Castration induced an earlier TMAX (0.25 vs 1 hr, greater CMAX (109.1 vs 68.1 ug/L, and a corresponding AUC increase (339.7 vs 231.8 hr*ug/L.  Administration of disulfiram caused more drastic CMAX and TMAX changes in male vs female rats that mirrored the effects of castration on first-pass metabolism, suggesting that the observed PK differences may be caused by ADH/ALDH expression. Brain concentrations paralleled plasma concentrations.Conclusions:  These findings indicate that sex differences in zolpidem PK are influenced by variation in the expression of ADH/ALDH due to gonadal androgens.

    Early initiation of sex work is prevalent among female sex workers (FSWs) worldwide. The objectives of this study were to investigate if early initiation of sex work was associated with: (1) consistent condom use, (2) condom negotiation self-efficacy or (3) condom use norms among alcohol-using FSWs in Mombasa, Kenya. In-person interviews were conducted with 816 FSWs in Mombasa, Kenya. Sample participants were: recruited from HIV prevention drop-in centres, 18 years or older and moderate risk drinkers. Early initiation was defined as first engaging in sex work at 17 years or younger. Logistic regression modelled outcomes as a function of early initiation, adjusting for drop-in centre, years in sex work, supporting others and HIV status. FSWs who initiated sex work early were significantly less likely to report consistent condom use with paying sex partners compared with those who initiated sex work in adulthood. There was no significant difference between groups in consistent condom use with non-paying sex partners. FSWs who initiated sex work early endorsed less condom negotiation self-efficacy with paying sex partners compared with FSWs who did not initiate sex work early. Findings highlight a need for early intervention for at-risk youth and adolescent FSWs, particularly in relation to HIV sexual risk behaviours. Evidence-based interventions for adolescent FSWs or adult FSWs who began sex work in adolescence should be developed, implemented and evaluated. Published by the BMJ Publishing Group Limited.

    Full Text Available Abstract Background Sexual offences are a global public health concern. Recent changes in the law in England and Wales have dramatically altered the legal landscape of sexual offences, but sexual assaults where the victim is voluntarily intoxicated by alcohol continue to have low conviction rates. Worldwide, students are high consumers of alcohol. This research aimed to compare male and female students in relation to their knowledge and attitudes about alcohol and sexual activity and to identify factors associated with being the victim of alcohol-related non-consensual sex. Methods 1,110 students completed an online questionnaire. Drinking levels were measured using the Alcohol Use Disorder Identification Test. Non-consensual sexual experiences were measured using the Sexual Experience Survey. Univariate and multivariate analyses were undertaken using chi square and backwards stepwise logistic regression respectively. Results A third of respondents had experienced alcohol-related non-consensual sex. Male and female students differed in the importance they gave to cues in deciding if a person wished to have sex with them and their understanding of the law of consent. 82.2% of women who had experienced alcohol-related non-consensual sex were hazardous drinkers compared to 62.9% who drank at lower levels (P Conclusions Alcohol-related coerced sexual activity is a significant occurrence among students; attitudinal and knowledge differences between males and females may explain this. Educational messages that focus upon what is deemed acceptable sexual behaviour, the law and rape myths are needed but are set against a backdrop where drunkenness is commonplace.

    Alcohol use is a public health problem in the Russian Federation. This study explored relationships between alcohol use and behavioral risks for HIV transmission among men who have sex with men (MSM) in Moscow, Russia. Alcohol use disorder identification test (AUDIT) scores for 1367 MSM participating in a cross-sectional survey and HIV testing were categorized to: "abstinence/low use", "hazardous use", "harmful use/dependency". Multiple logistic regression models compared dependent variables for sexual and drug use behaviors across alcohol use strata. Hazardous and harmful/dependent alcohol use were significantly associated with high-risk sexual behaviors and drug use. Harmful use/dependency was associated with an increased odds of having more than five male sex partners (last 12 months; adjusted odds ratios-AOR 1.69; 95 % CI 1.25-2.27), inconsistent condom use during anal intercourse (AOR 2.19; 95 % CI 1.61-2.96) and, among those using recreational drugs, injection drug use (last month; AOR 4.38: 95 % CI 1.13-17.07) compared to abstinent/low-level users. Harmful/dependent use was marginally associated with HIV infection (AOR 1.48; 95 % CI 0.97-2.25). HIV prevention efforts for MSM in Moscow may benefit from addressing problem alcohol use to mitigate high-risk behaviors.

  2. Sex differences in the interacting roles of impulsivity and positive alcohol expectancy in problem drinking: A structural brain imaging study

    Full Text Available Alcohol expectancy and impulsivity are implicated in alcohol misuse. However, how these two risk factors interact to determine problem drinking and whether men and women differ in these risk processes remain unclear. In 158 social drinkers (86 women assessed for Alcohol Use Disorder Identification Test (AUDIT, positive alcohol expectancy, and Barratt impulsivity, we examined sex differences in these risk processes. Further, with structural brain imaging, we examined the neural bases underlying the relationship between these risk factors and problem drinking. The results of general linear modeling showed that alcohol expectancy best predicted problem drinking in women, whereas in men as well as in the combined group alcohol expectancy and impulsivity interacted to best predict problem drinking. Alcohol expectancy was associated with decreased gray matter volume (GMV of the right posterior insula in women and the interaction of alcohol expectancy and impulsivity was associated with decreased GMV of the left thalamus in women and men combined and in men alone, albeit less significantly. These risk factors mediated the correlation between GMV and problem drinking. Conversely, models where GMV resulted from problem drinking were not supported. These new findings reveal distinct psychological factors that dispose men and women to problem drinking. Although mediation analyses did not determine a causal link, GMV reduction in the insula and thalamus may represent neural phenotype of these risk processes rather than the consequence of alcohol consumption in non-dependent social drinkers. The results add to the alcohol imaging literature which has largely focused on dependent individuals and help elucidate alterations in brain structures that may contribute to the transition from social to habitual drinking.

    We previously demonstrated that prodynorphin (PDYN) haplotypes and single nucleotide polymorphism (SNP) rs2281285 are associated with alcohol dependence and the propensity to drink in negative emotional states, and recent studies suggest that PDYN gene effects on substance dependence risk may be sex-related. We examined sex-dependent associations of PDYN variation with alcohol dependence and related phenotypes, including negative craving, time until relapse after treatment and the length of sobriety episodes before seeking treatment, in discovery and validation cohorts of European ancestry. We found a significant haplotype-by-sex interaction (p  =  0.03), suggesting association with alcohol dependence in males (p = 1E-4) but not females. The rs2281285 G allele increased risk for alcohol dependence in males in the discovery cohort (OR = 1.49, p = 0.002), with a similar trend in the validation cohort (OR = 1.35, p = 0.086). However, rs2281285 showed a trend towards association with increased negative craving in females in both the discovery (beta = 10.16, p = 0.045) and validation samples (OR = 7.11, p = 0.066). In the discovery cohort, rs2281285 was associated with time until relapse after treatment in females (HR = 1.72, p = 0.037); in the validation cohort, it was associated with increased length of sobriety episodes before treatment in males (beta = 13.49, p = 0.001). Our findings suggest that sex-dependent effects of PDYN variants in alcohol dependence are phenotype-specific.

    Full Text Available Abstract Background Cigarette/alcohol use and premarital sex, and their subsequent consequences on the well-being of college students, are international health promotion issues. However, little is known about the temporal relationship of these risk behaviors among Taiwanese college students. Methods This study utilizes data from the Taiwan Youth Project, a cohort sample of 20-year-olds (N = 2,119 with a 2-year follow-up, to explore the relationship between adolescent cigarette/alcohol use, and subsequent premarital sex. To incorporate the Taiwanese context where the normative value of abstinence until marriage remains strong, multivariate logistic regression models included data on premarital sex attitudes, stressful life events, peer influence, as well as family and individual factors which might influence this relationship. Results The sample consists of 49% male and 51% female college students. About 16% of the sample report having had premarital sex by age 20. After excluding sexually active youth, 20% of males and 13% of females report engaging in premarital sex in the 2-year follow-up interview. Multivariate logistic regression analyses reveal adolescent alcohol use is significantly associated with a higher likelihood of engaging in premarital sex for both genders; adolescent smoking is significantly associated with premarital sexual activity among males, but not females. Our results indicate liberal premarital sexual attitudes and stressful personal events are also significantly associated with premarital sexual activity. Conclusions These findings suggest health promotion programs for college students need to take developmental and gender perspectives into account. Future research to incorporate a broader, multi-cultural context into risk reduction materials is recommended.

    Full Text Available Objective. This research was conducted to assess the correlates of alcohol consumption and HIV/AIDS-related stigmatizing and discriminatory attitudes among men who have sex with men (MSM in Shandong province, China. Methods. A cross-sectional survey provided demographics, sexual behaviors, illicit drug use, alcohol consumptions, and service utilization. Results. Of 1,230 participants, 82.8% were single, 85.7% aged 3 times per week in the past six months. The average total score of stigmatizing and discriminatory attitude was 37.4 ± 4.4. More frequent episodes of alcohol use were independently associated with higher levels of HIV/AIDS-related stigma and discrimination, unprotected anal sex, bisexual identity, multiple male sex partners, drug use, and lower levels of education. Expressing higher levels of HIV/AIDS-related stigmatizing and discriminatory attitudes was independently associated with alcohol use, unprotected male anal sex, bisexuals, more male sex partners, commercial sex with men, and non-receipt of peer education in the past year. Conclusion. HIV/AIDS-related stigmatizing and discriminatory attitudes are common and associated with alcohol use and unprotected sex among MSM. The finding highlights the needs to develop programs that would reduce HIV/AIDS-related stigmatizing and discriminatory attitudes and strengthen alcohol use prevention and risk reduction initiatives among MSM.

    2016-01-01

    The notion of objective probability or chance, as a physical trait of the world, has proved elusive; the identification of chances with actual frequencies does not succeed. An adequate theory of chance should explain not only the connection of chance with statistics, but with degrees of belief, and more broadly the entire phenomenology of (seemingly) chance events and their measurement. Branching structure in the decoherence-based many worlds theory provides an account of what chance is that satisfies all these desiderata, including the requirement that chance involves uncertainty.

    2015-01-01

    Full Text Available Children exposed to substantial amounts of alcohol in utero display a broad range of morphological and behavioral outcomes, which are collectively referred to as fetal alcohol spectrum disorders (FASDs. Common to all children on the spectrum are cognitive and behavioral problems that reflect central nervous system dysfunction. Little is known, however, about the potential effects of variables such as sex on alcohol-induced brain damage. The goal of the current research was to utilize magnetoencephalography (MEG to examine the effect of sex on brain dynamics in adolescents and young adults with FASD during the performance of an auditory oddball task. The stimuli were short trains of 1 kHz “standard” tone bursts (80% randomly interleaved with 1.5 kHz “target” tone bursts (10% and “novel” digital sounds (10%. Participants made motor responses to the target tones. Results are reported for 44 individuals (18 males and 26 females ages 12 through 22 years. Nine males and 13 females had a diagnosis of FASD and the remainder were typically-developing age- and sex-matched controls. The main finding was widespread sex-specific differential activation of the frontal, medial and temporal cortex in adolescents with FASD compared to typically developing controls. Significant differences in evoked-response and time–frequency measures of brain dynamics were observed for all stimulus types in the auditory cortex, inferior frontal sulcus and hippocampus. These results underscore the importance of considering the influence of sex when analyzing neurophysiological data in children with FASD.

    Alcohol use disorder and depression are highly comorbid, and both conditions exhibit important sexual dimorphisms. Here, we aimed to investigate voluntary alcohol consumption after 6weeks of chronic mild stress (CMS) in Wistar rats - employed as an animal model of depression. Male and female rats were investigated, and changes in several molecular markers were analysed in frontal cortex (FCx) and hippocampal formation (HF). CMS induced depressive-like responses in the forced swimming test - increased immobility time - in male and female animals, without affecting anhedonia (sucrose preference test) nor motor activity (holeboard); body weight gain and food intake were diminished only among CMS males. Voluntary alcohol consumption was evaluated in a two-bottle choice paradigm (ethanol 20% versus tap water) for 4 consecutive days; females exhibited a higher preference for alcohol compared to male animals. In particular, alcohol consumption was significantly higher among CMS females compared to CMS male animals. Remarkably, similar changes in both male and female animals exposed to CMS were observed regarding the expression levels of NCAM-140KDa (decrease), GFAP and CB1R expression (increase) within the FCx as well as for HF PSD-95 levels (increase). However, contrasting effects in males and females were reported in relation to synaptophysin (SYN) protein levels within the FCx, HF CB1R expression (a decrease among male animals but an increase in females); while the opposite pattern was observed for NCAM-140KDa protein levels in the HF. A decrease in CB2R expression was only observed in the HF of CMS-females. The present study suggests that male and female animals might be differentially affected by CMS regarding later voluntary alcohol consumption. In this initial approach, cortical SYN, and NCAM-140KDa, CB1R and CB2R expression within the HF have arisen as potential candidates to explain such sex differences in behaviour. However, the depression-alcoholism

    OBJECTIVES: Adenosine signaling has been implicated in the pathophysiology of several psychiatric disorders including alcoholism, depression, and anxiety. Adenosine levels are controlled in part by transport across the cell membrane by equilibrative nucleoside transporters (ENTs). Recent evidence showed that a polymorphism in the gene encoding ENT1 is associated with comorbid depression and alcoholism in women. We have previously shown that deletion of ENT1 reduces ethanol intoxication and elevates alcohol intake in mice. Interestingly, ENT1 null mice display decreased anxiety-like behavior compared to wild-type littermates. However, our behavioral studies were performed only in male mice. Here, we extend our research to include female mice, and test the effect of ENT1 knockout on other behavioral correlates of alcohol drinking, including depressive and compulsive behavior, in mice. METHODS: To assess depression-like behavior, we used a forced swim test modified for mice. We examined anxiety-like behavior and locomotor activity in open field chambers, and perseverant behavior using the marble-burying test. Finally, we investigated alcohol consumption and preference in female mice using a two-bottle choice paradigm. RESULTS: ENT1 null mice of both sexes showed reduced immobility time in the forced swim test and increased time in the center of the open field compared to wild-type littermates. ENT1 null mice of both sexes showed similar locomotor activity levels and habituation to the open field chambers. Female ENT1 null mice displayed increased marble-burying compared to female wild-types, but no genotype difference was evident in males. Female ENT1 null mice showed increased ethanol consumption and preference compared to female wild-types. CONCLUSIONS: Our findings suggest that ENT1 contributes to several important behaviors involved in psychiatric disorders. Inhibition of ENT1 may be beneficial in treating depression and anxiety, while enhancement of ENT1 function

    Sex under the influence of drugs or alcohol is associated with high-risk sexual behavior. Heterosexual men (n = 505) in substance abuse treatment completed a computer-administered interview assessing sexual risk behaviors. Most men (73.3%) endorsed sex under the influence in the prior 90 days, and 39.1% endorsed sex under the influence during their most recent sexual event. Sex under the influence at the most recent event was more likely to involve anal intercourse, sex with a casual partner, and less condom use. Patients might benefit from interventions targeting sexual behavior and substance use as mutual triggers. (Am J Addict 2010;00:1-9).

    Literature from sub-Saharan Africa and elsewhere supports a global association between alcohol and HIV risk. However, more rigorous studies using multiple event-level methods find mixed support for this association, suggesting the importance of examining potential moderators of this relationship. The present study explores the assumptions of alcohol expectancy theory and alcohol myopia theory as possible moderators that help elucidate the circumstances under which alcohol may affect individuals' ability to use a condom. Participants were 82 individuals (58 women, 24 men) living with HIV who completed daily phone interviews for 42 days which assessed daily sexual behavior and alcohol consumption. Logistic generalized estimating equation models were used to examine the potential moderating effects of inhibition conflict and sex-related alcohol outcome expectancies. The data provided some support for both theories and in some cases the moderation effects were stronger when both partners consumed alcohol.

    Strong research evidence has shown that medical male circumcision significantly reduces heterosexual HIV acquisition among men. However, its effectiveness is enhanced by behavioural factors such as condom use. Currently, little is known of unprotected sex associated with male circumcision (MC) among alcohol-drinking tavern-going men, or whether engagement in unprotected sex may differ between men who have been traditionally circumcised and those who have been medically circumcised. The study sought to determine the relative importance of alcohol consumption and MC as correlates of unprotected sex and to compare the risk of engaging in unprotected sex between traditionally circumcised and medically circumcised tavern-going men from two rural villages in North-West province, South Africa. Data from 314 adult men (≥18 years) were analysed. The men were recruited from four bars/taverns using systematic sampling. They responded to questions regarding their demographic characteristics, alcohol consumption, circumcision status and method (where applicable), and engagement in unprotected sex. Descriptive analyses and bivariate and multivariate logistic regression analyses were conducted. Age, education, relationship status, alcohol consumption and traditional male circumcision (TMC) were independently and significantly associated with unprotected sex. Specifically, probable alcohol dependence and traditional circumcision were independent risk factors for engaging in unprotected sex among tavern-going men. Traditionally circumcised men had a higher risk of engaging in unprotected sex than medically circumcised men. Interventions aimed at reducing alcohol consumption, encouraging protective behaviour among men who have undergone TMC, and increasing condom use are needed in bar/tavern settings. HIV prevention education must be urgently incorporated into TMC programmes.

    Adolescent alcohol use is common and has serious immediate and long-term ramifications. While concurrent individual and context factors are robustly associated with adolescent alcohol use, the influence of early childhood factors, particularly in interaction with child sex, are less clear. Using a prospective community sample of 362 (190 girls), this study investigated sex differences in the joint influence of distal childhood and proximal adolescent factors on Grade 10 alcohol use. All risk factors and two-way early individual-by-context interactions, and interactions of each of these with child sex, were entered into the initial regression. Significant sex interactions prompted the use of separate models for girls and boys. In addition to the identification of early (family socioeconomic status, authoritative parenting style) and proximal adolescent (mental health symptoms, deviant friends) risk factors for both girls and boys, results highlighted important sex differences. In particular, girls with higher alcohol consumption at Grade 10 were distinguished by the interaction of early temperamental disinhibition and exposure to parental stress; boys with higher alcohol consumption at Grade 10 were distinguished primarily by early temperamental negative affect. Results have implications for the timing and type of interventions offered to adolescents.

    Alcohol abuse and alcoholism are major medical problems affecting both men and women. Previous animal studies reported a difference in c-Fos neuronal activation after chronic alcohol exposure; however, females remain an understudied population. To model chronic alcohol exposure match-pair fed adult male and female rats were administered 14 days of a liquid ethanol containing diet. Analysis focused on the central nucleus of the amygdala (CeA), a region integral to stress sensitivity and substance abuse. Immunocytochemical approaches identified cells containing ΔFosB, a marker of sustained neuronal activation, and activity patterns within the CeA were mapped by subdivision and rostral-caudal extent. Significant interactions were present between all groups, with gender differences noted among control groups, and ethanol exposed animals having the greatest number of ΔFosB immunoreactive cells indicating baseline dysregulation. Compared with c-Fos, a marker of recent neuronal activation, male ethanol treated animals had similar activity to controls, indicating a neuronal habituation not seen in females. Next, a cohort of animals were exposed to the forced swim test (FST), and c-Fos was examined in addition to FST behavior. Neuronal activity was increased in ethanol exposed animals compared to controls, and control females compared to males, indicating a potentiated stress response. Further, a population of activated neurons were shown to contain either corticotropin releasing factor or enkephalin. The present data suggest that dysregulation in the CeA neuronal activity may underlie some of the negative sequelae of alcohol abuse, and may, in part, underlie the distinctive response seen between genders to alcohol use.

    Adult attention deficit hyperactivity disorder (ADHD) shows a robust association with alcohol and cannabis misuse, and these relationships are expressed differently in males and females. Manifestation of specific ADHD symptom profiles, even in the absence of the full disorder, may also be related to problems with alcohol and cannabis, although these relationships have not been investigated in epidemiological studies. To address this question, we studied the sex-specific associations of ADHD symptomatology with problematic alcohol and cannabis use in a representative sample of adults aged 18 years and older residing in Ontario, Canada. Data were obtained from the Centre for Addiction and Mental Health Monitor, an ongoing cross-sectional telephone survey, between January 2011 and December 2013. Respondents (n =  5080) reported on current ADHD symptomatology, measured using the Adult ADHD Self-Report Version 1.1 Screener (ASRS-V1.1) and four additional items, and alcohol and cannabis use, which were measured using the Alcohol Use Disorders Identification Test (AUDIT) and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), respectively. Logistic regression analyses were conducted in men and women to test the association of each ADHD symptom cluster (hyperactivity, inattentiveness, impulsivity) with problematic alcohol and cannabis use. After controlling for age, education, and comorbid internalizing and externalizing psychopathology, hyperactive symptoms were associated with problematic alcohol use in both men and women and with problematic cannabis use in men. Impulsive symptoms were independently associated with problematic cannabis use in men. By contrast, inattentive symptomatology predicted problems with alcohol and cannabis only in women. In all models, age was negatively associated with substance misuse and externalizing behavior was positively correlated and the strongest predictor of hazardous alcohol and cannabis use.

    Full Text Available OBJECTIVE: To examine alcohol use and subsequent HIV risky behaviors among a sample of predominately ethnic minority people living with HIV/AIDS (PLWHA in a rural community in Yunnan Province, China. METHOD: A cross-sectional study with a face-to-face questionnaire interview was conducted among eligible participants. RESULTS: In total, 455 (94.4% out of 482 eligible HIV patients participated in the study. Of them, 82.6% were ethnic minorities; 15.4% were never married; 96.5% were sexually experienced; 55.4% had used drugs, 67% were receiving antiretroviral therapy (ART. Over 65% were ever drinkers; of whom 61.5% were current drinkers. Among current drinkers, 32.4% drank daily and 41.2% were hazardous drinkers. Chinese white wine was the preferred choice. Higher level of alcohol use among drinkers in the preceding month was positively associated with being males (OR = 2.76, 95%CI: 1.03-7.43, ethnic minorities (OR Jingpo = 2.21, 95%CI: 1.06-4.59; OR other minorities = 3.20, 95%CI: 1.34-7.62, higher education (OR1-6 = 1.98, 95%CI: 0.99-3.96; OR≥7 = 2.35, 95%CI: 1.09-5.06 and being ART-naive (OR = 2.69, 95%CI: 1.67-4.32. About 39% of ever drinkers reported having engaged in sex after drinking since HIV diagnosis. Those who were younger than 46 years (OR16-25 = 7.77, 95%CI: 1.22-49.60, OR26-35 = 2.79, 95%CI: 1.06-7.35, OR36-45 = 2.96, 95%CI: 1.57-7.58, hazardous drinkers (OR = 1.99, 95%CI: 1.00-3.97 and drug users (OR = 3.01, 95%CI: 1.19-7.58 were more likely to have had sex after drinking. Approximately 56% of drug users had used drugs after drinking. CONCLUSIONS: High prevalence of alcohol use and subsequent risky behaviors including sexual engagement and drug use among HIV patients in rural Yunnan require tremendous and integrated efforts for prevention and control of alcohol and drug abuse and HIV spreading.

    Full Text Available Background: In vitro and in vivo studies have demonstrated the role of the acid sphingomyelinase (ASM in pathophysiological processes and alterations in response to ethanol exposure. Cellular and plasmatic ASM activities are increased in male alcohol dependent patients and decrease during physical withdrawal. Methods: Here, we analyzed the time course of ASM in male and also female acutely intoxicated patients during alcohol withdrawal and compared the activity levels to those under long-term maintenance treatment. Craving and further psychometric parameters were assessed by questionnaires. Results: The gradual decrease of serum ASM was confirmed in males (pConclusion: These data support the potential of ASM as a biomarker for the course of withdrawal therapy in males and provide the first associations of this enzyme with psychological variables such as craving and depression.

    This study evaluates the Especially for Daughters intervention, which aims to provide urban Black and Latino parents with information and skills to support their daughters in delaying sexual initiation and alcohol use. In a randomized field trial, 268 families with sixth-graders were recruited from New York City public schools and assigned either to the intervention, a set of audio CDs mailed home; an attention-controlled condition (print materials); or controls. Girls completed classroom baseline and three follow-up surveys, and telephone surveys were conducted with parents. At follow-up, girls in the intervention reported fewer sexual risks (adjusted odds ratio [AOR] = 0.39, confidence interval [CI] = 0.17-0.88) and less drinking (AOR = 0.38, CI = 0.15-0.97, p sex and more communication on these topics.

    2013-04-01

    Full Text Available OBJECTIVE: Alcohol and other drug use appears to reduce decision-making ability and increase the risk of unsafe sex, leading to possible unplanned pregnancies, sexually transmitted diseases/human immunodeficiency virus/HIV transmission, and multiple sexual partners. This study aimed to test the hypothesis that risky sexual behaviors among adolescents are associated with legal and illegal drug use. METHODS: A national cross-sectional survey of 17,371 high-school students was conducted in 2010. Students were selected from 789 public and private schools in each of the 27 Brazilian state capitals by a multistage probabilistic sampling method and answered a self-report questionnaire. Weighted data were analyzed through basic contingency tables and logistic regressions testing for differences in condom use among adolescents who were sexually active during the past month. RESULTS: Approximately one third of the high school students had engaged in sexual intercourse in the month prior to the survey, and nearly half of these respondents had not used a condom. While overall sexual intercourse was more prevalent among boys, unsafe sexual intercourse was more prevalent among girls. Furthermore, a lower socioeconomic status was directly associated with non-condom use, while binge drinking and illegal drug use were independently associated with unsafe sexual intercourse. CONCLUSION: Adolescent alcohol and drug use were associated with unsafe sexual practices. School prevention programs must include drug use and sexuality topics simultaneously because both risk-taking behaviors occur simultaneously.

    Prevalence of alcohol-related harms in England are among the highest in Europe and represents an important policy issue. Understanding how alcohol-related trends vary by demographic factors is important for informing policy debates. The aim of our study was to examine trends in alcohol-related admissions to hospital in England, with a focus on variations by sex, age and socioeconomic deprivation. We used data on hospital admissions for England for the financial years 2002/03 to 2013/14. Our four main outcome variables were acute and chronic conditions wholly and partially attributable to alcohol consumption. We also looked at four specific conditions wholly attributable to alcohol. Socioeconomic deprivation was measured using the English Indices of Deprivation of a patient's residence (categorised by quintile). We calculated crude rates, age-specific rates (visualised by Lexis plots) and directly standardised rates by deprivation category, separately for males and females. Total admissions for all alcohol-attributable admissions increased from 201,398 in 2002/03 to 303,716 in 2013/14. The relative increase of these admissions was larger than compared to non-alcohol attributable admissions. Acute admissions wholly attributable to alcohol had the largest relative increase of our outcome measures, and displayed a bimodal distribution with higher rates in adolescence/young adults and middle age. Chronic conditions wholly attributable to alcohol were concentrated in middle age (particularly males). While admission rates were generally higher for males, females had higher rates of hospitalisations due to 'Intentional self-poisoning due to alcohol'. We also found evidence of wide social inequalities by level of deprivation, which were wider for men than compared to women across all of our outcome measures other than 'Intentional self-poisoning due to alcohol'. Our study expands the evidence base to help understand population level trends in alcohol-related admissions by

  12. Mortality and potential years of life lost attributable to alcohol consumption by race and sex in the United States in 2005.

    Full Text Available BACKGROUND: Alcohol has been linked to health disparities between races in the US; however, race-specific alcohol-attributable mortality has never been estimated. The objective of this article is to estimate premature mortality attributable to alcohol in the US in 2005, differentiated by race, age and sex for people 15 to 64 years of age. METHODS AND FINDINGS: Mortality attributable to alcohol was estimated based on alcohol-attributable fractions using indicators of exposure from the National Epidemiologic Survey on Alcohol and Related Conditions and risk relations from the Comparative Risk Assessment study. Consumption data were corrected for undercoverage (the observed underreporting of alcohol consumption when using survey as compared to sales data using adult per capita consumption from WHO databases. Mortality data by cause of death were obtained from the US Department of Health and Human Services. For people 15 to 64 years of age in the US in 2005, alcohol was responsible for 55,974 deaths (46,461 for men; 9,513 for women representing 9.0% of all deaths, and 1,288,700 PYLL (1,087,280 for men; 201,420 for women representing 10.7% of all PYLL. Per 100,000 people, this represents 29 deaths (29 for White; 40 for Black; 82 for Native Americans; 6 for Asian/Pacific Islander and 670 PYLL (673 for White; 808 for Black; 1,808 for Native American; 158 for Asian/Pacific Islander. Sensitivity analyses showed a lower but still substantial burden without adjusting for undercoverage. CONCLUSIONS: The burden of mortality attributable to alcohol in the US is unequal among people of different races and between men and women. Racial differences in alcohol consumption and the resulting harms explain in part the observed disparities in the premature mortality burden between races, suggesting the need for interventions for specific subgroups of the population such as Native Americans.

    Some evidence suggests that risk reduction programming for sexual risk behaviors (SRB) has been minimally effective, which emphasized the need for research on etiological and mechanistic factors that can be addressed in prevention and intervention programming. Childhood sexual and physical abuse have been linked with SRB among older adolescents and emerging adults; however, pathways to SRB remain unclear. This study adds to the literature by testing a model specifying that traumatic intrusions after early abuse may increase risk for alcohol problems, which in turn may increase the likelihood of engaging in various types of SRB. Participants were 1,169 racially diverse college students (72.9% female, 37.6% black/African-American, and 33.6% white) who completed anonymous questionnaires assessing child abuse, traumatic intrusions, alcohol problems, and sexual risk behavior. The hypothesized path model specifying that traumatic intrusions and alcohol problems account for associations between child abuse and several aspects of SRB was a good fit for the data; however, for men, stronger associations emerged between physical abuse and traumatic intrusions and between traumatic intrusions and alcohol problems, whereas for women, alcohol problems were more strongly associated with intent to engage in risky sex. Findings highlight the role of traumatic intrusions and alcohol problems in explaining paths from childhood abuse to SRB in emerging adulthood, and suggest that risk reduction programs may benefit from an integrated focus on traumatic intrusions, alcohol problems, and SRB for individuals with abuse experiences.

    Scientific evidence has suggested that genetic factors accounted for more than half of the vulnerability of developing alcohol use problems. However, collecting genetic data poses a significant challenge for most population-based behavioral studies. The aim of this study was to assess the utilities of a pedigree-based proxy measure of genetic predisposition of drinking (GPD) and its effect on alcohol use behaviors as well as its interactions with personal and environmental factors. In the current study, cross-sectional data were collected from 700 female sex workers (FSW) in Guangxi, China. Participants provided information on a pedigree-based proxy measure of GPD and their alcohol use behaviors. Chi-square and independent t-test was applied for examining the bivariate associations between GPD and alcohol use behaviors; multivariate and ordinal regression models were used to examine the effect of GPD on alcohol use. This study found that women with a higher composite score of GPD tended to have a higher risk of alcohol use problem compared to their counterparts (p pedigree-based measure provided a useful proxy of GPD among participants. Both FSW's mental health and health care access interact with GPD and affect their drinking patterns. By understanding the genetic basis of alcohol use, we can develop scalable and efficacious interventions that will take into consideration the individual risk profile and environmental influences.

    The purpose of the present study was to investigate the potential associations of binge drinking detected at the exit of nightclubs and risk behaviors and alcohol effects just after leaving the venue in a representative sample of Brazilian nightclub patrons according to sex. For this purpose, a portal survey study called Balada com Ciência was conducted in 2013 in the megacity of São Paulo, Brazil, using a two-stage cluster sampling survey design. Individual-level data were collected in 2422 subjects at the entrance and 1822 subjects at the exit of 31 nightclubs, and breath alcohol concentration (BrAC) was measured using a breathalyzer. The following day, 1222 patrons answered an online follow-up survey that included questions about risk behaviors and alcohol effects practiced just after leaving the nightclub. Weighted logistic regressions were used to analyze binge drinking associated with risk behaviors by sex. For both sexes, the most prevalent risk behaviors practiced after leaving a nightclub were drinking and driving (men=27.9%; women=20.4%), the use of illicit drugs (men=15.8%; women=9.4%) and risky sexual behavior (men=11.4%; women=6.8%). The practice of binge drinking increased the behavior of illicit drug use after leaving the nightclub by 2.54 times [95% CI: 1.26-5.09] among men who drank and increased the risk of an episode of new alcohol use by 5.80 times [95% CI: 1.50-22.44] among women who drank. Alcoholic blackouts were more prevalent among men [OR=8.92; 95% CI: 3.83-20.80] and women [OR= 5.31; 95% CI: 1.68-16.84] whose BrAC was equivalent to binge drinking compared with patrons with a lower BrAC. Public policies aiming to reduce patrons' BrAC at the exit of nightclubs, such as staff training in responsible beverage service and legislation to prevent alcohol sales to drunk individuals, would be useful to protect patrons from the risk behaviors associated with binge drinking in nightclubs.

    Alcohol use is a risk factor for the acquisition of human immunodeficiency virus (HIV) among African American men who have sex with men (MSM). Mobile phone-based ecological momentary assessments (EMA) could minimize bias due to retrospective recall and thus provide a better understanding of the social and structural context of alcohol use and its relationship with HIV-related risk behaviors in this population as well as other highly stigmatized populations. We describe the study design and the implementation, feasibility, reactivity, and acceptability of an EMA study of alcohol use and HIV-related behaviors among African American MSM in Baltimore. Participants were recruited through flyers and word-of-mouth in Baltimore from September 2013 to November 2014. Each participant was loaned an Android smartphone and instructed to respond to multiple prompts from the mobile app for 4 weeks. Data were collected through (1) random prompts delivered three times daily assessing participants' location, activity, mood, and social context, (2) daily prompts capturing drinking and sex events occurring in the past 24 hours, and (3) event-contingent responses collecting participants' self-reported episodes of drinking. A total of 16 participants enrolled in the study. The current analyses focused on 15 participants who completed at least 24 days of follow-up (mean follow-up time 29 days; range 24-35 days). Study participants (N=15) were a median 38 years of age (range 27-62 years) with low levels of income and educational attainment. Ten individuals self-reported living with HIV/AIDS, over half reported drinking alcohol at least 2-3 times a week, and a third reported binge drinking (ie, 6 or more drinks on one occasion) on a weekly basis. Based on the Alcohol Use Disorders Identification Test (AUDIT) score, nearly half were classified as hazardous drinkers (score 8-15) and a fifth were likely dependent (score ≥16). A total of 140 participant-initiated events were reported, and 75

    Schelling showed how residential segregation can arise even in a population that is tolerant of diversity. Bruch and Mare challenge this conclusion, claiming that it depends on threshold preference functions that are not empirically plausible. When they increased sensitivity to small changes in ethnic composition, using both linear and empirical preference functions, segregation largely disappeared. They conclude that tipping at the population level (into segregation) depends on tipping at the individual level (a critical point above and below which the individual is indifferent). However, when we replicated their model, we discovered that the results they report for both linear and empirical preferences were incorrect. We found that sensitivity to change can lead to integration in an ethnocentric population that prefers in-group neighbors, but only if ethnic preferences are sufficiently weak relative to chance. When ethnic preferences are sufficiently strong, segregation is greater with linear than with thre...

  8. Effects of sex and deletion of neuropeptide Y2 receptors from GABAergic neurons on affective and alcohol drinking behaviors in mice

    Directory of Open Access Journals (Sweden)

    Nora M McCall

    2013-12-01

    Full Text Available A large literature has demonstrated that neuropeptide Y (NPY regulates many emotional and reward-related behaviors via its primary receptors, Y1R and Y2R. Classically, NPY actions at postsynaptic Y1R decrease anxiety, depression, and alcohol drinking, while its actions at presynaptic Y2R produce the opposite behavioral phenotypes. However, emerging evidence suggests that activation of Y2R can also produce anxiolysis in a brain region and neurotransmitter system-dependent fashion. Further, numerous human and rodent studies have reported that females display higher levels of anxiety, depression, and alcohol drinking. In this study, we evaluated sex differences and the role of Y2R on GABAergic transmission in these behaviors using a novel transgenic mouse that lacks Y2R specifically in VGAT-expressing neurons (VGAT-Y2R knockout. First, we confirmed our genetic manipulation by demonstrating that Y2R protein expression was decreased and that a Y2R agonist could not alter GABAergic transmission in the extended amygdala, a limbic brain region critically implicated in the regulation of anxiety and alcohol drinking behaviors, using immunofluorescence and slice electrophysiology. Then, we tested male and female VGAT-Y2R knockout mice on a series of behavioral assays for anxiety, depression, fear, anhedonia, and alcohol drinking. We found that females displayed greater basal anxiety, higher levels of ethanol consumption, and faster fear conditioning than males, and that knockout mice exhibited enhanced depressive-like behavior in the forced swim test. Together, these results confirm previous studies that demonstrate higher expression of negative affective and alcohol drinking behaviors in females than males, and they highlight the importance of Y2R function in GABAergic systems in the expression of depressive-like behavior.

    Full Text Available Peru's HIV epidemic is concentrated among men who have sex with men (MSM. The contribution of alcohol use disorders (AUDs to known high-risk behaviors associated with HIV transmission in this context has not been well characterized.Between June and October 2011, 5,148 sexually active MSM were recruited using convenience sampling in five cities to participate in a cross-sectional bio-behavioral survey. Five high-risk sexual criteria previously associated with incident HIV infection in this setting were selected a priori as the dependent outcomes. Screening for AUDs used the validated Alcohol Use Disorders Identification Test (AUDIT and AUDS were stratified by severity. Unadjusted and adjusted odds ratios (AOR were computed to establish the independent correlates of the five dependent outcomes.The majority (62.8% of participants met screening criteria for having an AUD, which were independently correlated with each of the following high-risk sexual risk behaviors in the previous 6 months: 1 >5 sexual partners [AOR = 1.76; (1.54-2.02]; 2 sex with an HIV-infected partner [AOR = 1.29; (1.03-1.62]; 3 having a sexually transmitted infection [AOR = 1.38; (1.13-1.68]; 4 being a sex worker [AOR = 1.61; (1.40-1.87]; and 5 unprotected sex during last encounter [AOR = 1.22; (1.09-1.38]. Recent drug use was also correlated with having >5 sexual partners [AOR = 1.42 (1.19-1.71], sex work [AOR = 1.97 (1.63-2.39] and unprotected sex during last encounter [AOR = 1.31 (1.11-1.54]. For each dependent variable, the association with AUDs significantly increased with increasing AUD severity.AUDs are highly prevalent among MSM in Peru and are associated with increased HIV risk-taking behaviors that are associated with HIV transmission. Strategies that target problematic drinking such as medication-assisted therapy, behavioral counseling and structural interventions could potentially reduce risky behaviors and ultimately reduce HIV transmission among MSM in Peru.

  10. The Role of Alcohol Use during Sexual Situations in the Relationship between Sexual Revictimization and Women’s Intentions to Engage in Unprotected Sex

    Research has demonstrated relationships among childhood sexual abuse, adult sexual assault, and sexual risk taking. This study proposes that one mechanism through which the victimization-sexual risk taking relationship works is through an increased likelihood of drinking during sexual situations. Using path analysis, the current study explores this hypothesis in a sample of 230 women. The model illustrates that women with a history of child and adult sexual victimization reported greater intentions to engage in unprotected sex and that this relationship is in part accounted for by an increased likelihood of drinking in sexual situations. The results suggest that sexual risk reduction programs and sexual assault treatment programs should educate women about the alcohol-involved sexual risk taking that often follows sexual assault victimization.

    Full Text Available Abstract Background The prevalence of alcohol, tobacco and illicit drug use has been reported to be higher amongst lesbian and bisexual women (LBW than their heterosexual counterparts. However, few studies have been conducted with this population in Australia and rates that have been reported vary considerably. Methods A self-completed questionnaire exploring a range of health issues was administered to 917 women aged 15-65 years (median 34 years living in Western Australia, who identified as lesbian or bisexual, or reported having sex with another woman. Participants were recruited from a range of settings, including Perth Pride Festival events (67.0%, n = 615, online (13.2%, n = 121, at gay bars and nightclubs (12.9%, n = 118, and through community groups (6.9%, n = 63. Results were compared against available state and national surveillance data. Results LBW reported consuming alcohol more frequently and in greater quantities than women in the general population. A quarter of LBW (25.7%, n = 236 exceeded national alcohol guidelines by consuming more than four standard drinks on a single occasion, once a week or more. However, only 6.8% (n = 62 described themselves as a heavy drinker, suggesting that exceeding national alcohol guidelines may be a normalised behaviour amongst LBW. Of the 876 women who provided data on tobacco use, 28.1% (n = 246 were smokers, nearly double the rate in the female population as a whole. One third of the sample (33.6%, n = 308 reported use of an illicit drug in the previous six months. The illicit drugs most commonly reported were cannabis (26.4%, n = 242, meth/amphetamine (18.6%, n = 171, and ecstasy (17.9%, n = 164. Injecting drug use was reported by 3.5% (n = 32 of participants. Conclusion LBW appear to use alcohol, tobacco and illicit drugs at higher rates than women generally, indicating that mainstream health promotion messages are not reaching this group or are not perceived as relevant.

  14. Camp life: Are northern work camps safe havens for a migrant workforce, or dens of iniquity rampant with sex, drugs and alcohol?

    2004-02-01

    Two studies, dealing with life in work camps in northern Alberta and yielding contradictory results, are discussed. One study by a graduate student in sociology found that many of the men and women housed in work camps in remote locations of the northeastern oilsands belt use drugs, alcohol and casual sex to relieve boredom and loneliness. The other study, commissioned by the Athabasca Regional Issues Working Group (RWIG) found that camp workers visit Fort McMurray on the average of just over once a week, and use that time to take care of normal business, such as visiting health care professionals, buying gasoline, clothing, etc. It found no evidence of widespread sex, or drug or alcohol abuse among work camp residents. The RWIG study surveyed 25 per cent of the 6,272 worker population living in three camps in the Wood Buffalo region during June 2003. The study prepared by V. Taylor for a M.A. degree in sociology at the University of Calgary was severely criticized, primarily for its conclusions being based on a sample size of only nine men and one woman. Despite the criticism, the Taylor study made headlines across the country and has been instrumental in raising awareness of the special needs of a mobile workforce. A more broadly-based study is in progress at the University of Alberta, supported by the RCMP and a number of workplace stakeholders. Its objectives are to examine the situation more thoroughly, identify gaps in services and to explore long term solutions to what is undeniably a serious problem, indicated, if not proven, by the Taylor study.

    Pence, Charles H

    2015-04-01

    Work throughout the history and philosophy of biology frequently employs 'chance', 'unpredictability', 'probability', and many similar terms. One common way of understanding how these concepts were introduced in evolution focuses on two central issues: the first use of statistical methods in evolution (Galton), and the first use of the concept of "objective chance" in evolution (Wright). I argue that while this approach has merit, it fails to fully capture interesting philosophical reflections on the role of chance expounded by two of Galton's students, Karl Pearson and W.F.R. Weldon. Considering a question more familiar from contemporary philosophy of biology--the relationship between our statistical theories of evolution and the processes in the world those theories describe--is, I claim, a more fruitful way to approach both these two historical actors and the broader development of chance in evolution.

    Although alcohol consumption is frequently perceived as a driver of condomless sex and subsequent HIV acquisition, the causal nature of this relationship remains unclear, and little is known about alcohol’s direct versus indirect impact on the sexual risk dynamics of those who are HIV-positive. To address this gap, we present the protocol for an in-progress NIAAA-funded controlled experiment, wherein a sample of HIV-positive men-who-have-sex-with-men (MSM) undergoes an alcohol consumption manipulation (alcohol/placebo/control) and sexual arousal induction (sexually aroused/non-aroused), and then reports intentions to engage in condom-protected and condomless sexual acts with hypothetical sexual partners differing in HIV serostatus (HIV+/HIV−/HIV status unknown), condom use preference (use/don’t use/not stated), and physical attractiveness (attractive/unattractive). Study outcomes will identify alcohol’s impact on HIV-positive MSM’s condomless sex intentions in the context of experimentally-manipulated factors as well as risk-relevant personality traits and alcohol-related expectancies. Detailed experimental procedures, ethical considerations, and potential implications for HIV prevention are discussed. PMID:26163147

  19. Prevalence of intestinal nematodes in alcoholic patients

    2002-01-01

    Full Text Available We report the results of a retrospective study on the frequency of intestinal nematodes among 198 alcoholic and 440 nonalcoholic patients at the University Hospital Cassiano Antonio Moraes in Vitória, ES, Brazil. The control sample included 194 nonalcoholic patients matched according to age, sex and neighborhood and a random sample of 296 adults admitted at the same hospital. Stool examination by sedimentation method (three samples was performed in all patients. There was a significantly higher frequency of intestinal nematodes in alcoholics than in controls (35.3% and 19.2%, respectively, due to a higher frequency of Strongyloides stercoralis (21.7% and 4.1%, respectively. Disregarding this parasite, the frequency of the other nematodes was similar in both groups. The higher frequency of S. stercoralis infection in alcoholics could be explained by immune modulation and/or by some alteration in corticosteroid metabolism induced by chronic ethanol ingestion. Corticosteroid metabolites would mimic the worm ecdisteroids, that would in turn increase the fecundity of females in duodenum and survival of larvae. Consequently, the higher frequency of Strongyloides larvae in stool of alcoholics does not necessarily reflect an increased frequency of infection rate, but only an increased chance to present a positive stool examination using sedimentation methods.

    High rates of cognitive impairment persist in human immunodeficiency virus (HIV) infection, despite improved health outcomes and reduced mortality through widespread use of antiretroviral therapy (ART). Heavy alcohol use and cigarette smoking are potential contributors to neurocognitive impairment in people living with HIV (PLWH), yet few studies have examined their influence concurrently. Here we investigated the effects of self-reported alcohol use and smoking on learning, memory, processing speed, verbal fluency, and executive function in 124 HIV-positive men who have sex with men [age (mean ± SD) = 42.8 ± 10.4 years], engaged with medical care. All participants were heavy drinkers. Duration of HIV infection averaged 9.9 ± 7.6 years, and 92.7% were on a stable ART regimen. Participants completed a neuropsychological battery and assessment of past 30-day substance use. Average number of drinks per drinking day (DPDD) was 5.6 ± 3.5, and 33.1% of participants were daily smokers. Rates of neurocognitive impairment were the highest in learning (50.8%), executive function (41.9%), and memory (38.0%). Multiple regression models tested DPDD and smoking status as predictors of neurocognitive performance, controlling for age and premorbid intelligence. Smoking was significantly, negatively related to verbal learning (p = .046) and processing speed (p = .001). DPDD was a significant predictor of learning (p = .047) in a model that accounted for the interaction of DPDD and smoking status. As expected, premorbid intelligence significantly predicted all neurocognitive scores (ps < .01), and older age was associated with slower processing speed (ps < .01). In conclusion, smoking appears to be associated with neurocognitive functioning deficits in PLWH beyond the effects of heavy drinking, aging, and premorbid intelligence. Smoking cessation interventions have the potential to be an important target for improving functional outcomes

    Persistent deficits in social behavior, motor behavior, and behavioral flexibility are among the major negative consequences associated with exposure to ethanol during prenatal development. Prior work from our laboratory has linked moderate prenatal alcohol exposure (PAE) in the rat to deficits in these behavioral domains, which depend upon the ventrolateral frontal cortex (Hamilton et al., 2014) [20]. Manipulations of the social environment cause modifications of dendritic morphology and experience-dependent immediate early gene expression in ventrolateral frontal cortex (Hamilton et al., 2010) [19], and may yield positive behavioral outcomes following PAE. In the present study we evaluated the effects of housing PAE rats with non-exposed control rats on adult behavior. Rats of both sexes were either paired with a partner from the same prenatal treatment condition (ethanol or saccharin) or from the opposite condition (mixed housing condition). At four months of age (∼3 months after the housing manipulation commenced), social behavior, tongue protrusion, and behavioral flexibility in the Morris water task were measured as in (Hamilton et al., 2014) [20]. The behavioral effects of moderate PAE were primarily limited to males and were not ameliorated by housing with a non-ethanol exposed partner. Unexpectedly, social behavior, motor behavior, and spatial flexibility were adversely affected in control rats housed with a PAE rat (i.e., in mixed housing), indicating that housing with a PAE rat has broad behavioral consequences beyond the social domain. These observations provide further evidence that moderate PAE negatively affects social behavior, and underscore the importance of considering potential negative effects of housing with PAE animals on the behavior of critical comparison groups.

    2015-01-01

    Charles Darwin proposed the theory that evolution of live organisms is based on random variation and natural selection. Jacques Monod, in his classic book Chance and Necessity, published 45 years ago, presented his thesis that the biosphere does not contain a predictable class of objects or events, but constitutes a particular occurrence, compatible indeed with the first principles but not deducible from those principles. The biosphere is therefore essentially unpredictable. In his book, Monod expounded at length on the conflict between science and religion. He saw religion as a collection of primitive myths that had been blown to shreds by science. At every turn, Monod emphasized the role of chance in human existence, an idea that is antithetical to essentially every religious doctrine that places humans as some inevitable intention of a Creator.

    2012-01-01

    This paper presents a novel dynamic programming algorithm with a joint chance constraint, which explicitly bounds the risk of failure in order to maintain the state within a specified feasible region. A joint chance constraint cannot be handled by existing constrained dynamic programming approaches since their application is limited to constraints in the same form as the cost function, that is, an expectation over a sum of one-stage costs. We overcome this challenge by reformulating the joint chance constraint into a constraint on an expectation over a sum of indicator functions, which can be incorporated into the cost function by dualizing the optimization problem. As a result, the primal variables can be optimized by a standard dynamic programming, while the dual variable is optimized by a root-finding algorithm that converges exponentially. Error bounds on the primal and dual objective values are rigorously derived. We demonstrate the algorithm on a path planning problem, as well as an optimal control problem for Mars entry, descent and landing. The simulations are conducted using a real terrain data of Mars, with four million discrete states at each time step.

    1981-01-01

    A population of 399 persons (180 women and 219 men) has been examined. Anamnesis included detailed inquiries about smoking habit and alcohol drinking. In the laboratory, lead concentration in blood and ALAD activity in erythrocytes have been determined on empty stomach. No differences have been found in the mean lead concentration determined by sex, whereas the mean ALAD activity is higher in women than in men. The subjects' age has affected the test parameters neither in men nor women. In smoking men no changes in the mean lead concentration in blood and mean ALAD activity in erythrocytes have been found. In smoking women, the mean lead concentration is not changed, but the mean ALAD activity is lower. Alcohol drinking in men does not change the values of the test parameters, whereas drinking women have revealed higher mean blood lead concentration.

    Full Text Available We discuss and develop the convex approximation for robust joint chance constraints under uncertainty of first- and second-order moments. Robust chance constraints are approximated by Worst-Case CVaR constraints which can be reformulated by a semidefinite programming. Then the chance constrained problem can be presented as semidefinite programming. We also find that the approximation for robust joint chance constraints has an equivalent individual quadratic approximation form.

    Full Text Available Once a retrovirus infects a eukaryotic cell and integrates within chromosomal DNA, it becomes part of its genome and can be activated/transcribed/translated to produce viral proteins and/or new viral particles. Over the years, some of these retroviruses may lose their pathogenicity and become adapted to the new host. Under these conditions, retroviruses can paradoxically ameliorate the functional portfolio of the infected cell, thus potentially increasing its functionality and/or chances of survival in a difficult environment. Individuals whose cells are infected by retroviruses have acquired, in the last millions of years, innovative functions that, once transmitted to the new generation through germinal cells, have become essential for their homeostasis, or even for their survival. This is the case of some endogenous retroviruses, whose products are mandatory for the proper vascularization of human placenta. To our knowledge, there are no natural means able to selectively eliminate retroviral genes from an infected cell or an individual. Therefore, the chances of getting naturally cured by retroviruses, once infection is set and viral genomes are spread into the body, are minimal or absent. HIV is a retrovirus that behaves as all other retroviruses that interacted with humans in the past millennia. Its fate is to remain forever within the infected body. For these reasons, the chances of getting rid of HIV infection and being biologically cured (that is, eliminating all viral genomes from the body are very limited if we consider current knowledge, biotechnology and available medical tools (yet it cannot be fully excluded in very peculiar cases. The option offered by the so-called “functional cure” is different. In this case, medical manipulation may create conditions whereby viral genomes, decreased in number and function by proper therapies/vaccines, are no longer able to harm the host for an indefinite period of time. Patients do remain

    Research has demonstrated a link between alcohol use and multiple forms of risky sexual behavior, particularly among college-age individuals. Studies have also linked heavy alcohol use to other problems, such as impaired consciousness resulting from an alcohol-induced blackout, which may impact sexual decision making. However, research has rarely examined sexual risk taking (SRT) in relation to blackouts, nor has it examined this construct during the precollege transition (i.e., the interval of time between high school graduation and college matriculation). This study examined the intersection between alcohol-involved SRT, blackouts, and gender in a sample of precollege individuals with prior alcohol use (N = 229; 54% male, 63% White). Results indicated that, despite drinking less per occasion, women reporting recent blackouts were at increased risk for experiencing unwanted, unsafe, and regretted sexual behaviors compared to men with recent blackouts and their peers with no recent blackouts. Women with recent blackouts also reported differences in alcohol expectancies that may increase their risk for experiencing negative consequences while drinking, including higher social expectancies and lower negative expectancies of danger. Future directions for research and implications for precollege interventions are discussed.

  16. Chance of Necessity: Modeling Origins of Life

    Pohorille, Andrew

    2006-01-01

    The fundamental nature of processes that led to the emergence of life has been a subject of long-standing debate. One view holds that the origin of life is an event governed by chance, and the result of so many random events is unpredictable. This view was eloquently expressed by Jacques Monod in his book Chance or Necessity. In an alternative view, the origin of life is considered a deterministic event. Its details need not be deterministic in every respect, but the overall behavior is predictable. A corollary to the deterministic view is that the emergence of life must have been determined primarily by universal chemistry and biochemistry rather than by subtle details of environmental conditions. In my lecture I will explore two different paradigms for the emergence of life and discuss their implications for predictability and universality of life-forming processes. The dominant approach is that the origin of life was guided by information stored in nucleic acids (the RNA World hypothesis). In this view, selection of improved combinations of nucleic acids obtained through random mutations drove evolution of biological systems from their conception. An alternative hypothesis states that the formation of protocellular metabolism was driven by non-genomic processes. Even though these processes were highly stochastic the outcome was largely deterministic, strongly constrained by laws of chemistry. I will argue that self-replication of macromolecules was not required at the early stages of evolution; the reproduction of cellular functions alone was sufficient for self-maintenance of protocells. In fact, the precise transfer of information between successive generations of the earliest protocells was unnecessary and could have impeded the discovery of cellular metabolism. I will also show that such concepts as speciation and fitness to the environment, developed in the context of genomic evolution also hold in the absence of a genome.

  17. Chance, choice, and the future of reproduction.

    Science.gov (United States)

    Miller, W B

    1983-11-01

    The evolution of reproduction has been characterized by the development of complex biological and behavioral mechanisms that serve to regulate chance events. Human reproduction has been characterized by the increasing importance of individual choice. Some contemporary manifestations of this broad trend are the high incidence of contraceptive and "proceptive" behavior among couples in Western, industrialized nations. The former behavior willingly attempts to prevent conception while the latter actively attempts to induce conception (such as concentrating intercourse around the time of ovulation). Both patterns of behavior indicate that a choice is being made. A 3-year study of 1000 women revealed proceptive behavior as the most important factor predicting occurance of conception among married couples in the United States. The general strategeis people follow while making childbearing decisions: termination, sequencing, and pre-planning form a continuum following the historical trend toward greater reproductive control. In the terminating strategy, a couple makes no decision about child bearing until the number of children they have become enough or too much. In the sequencing strategy, decisions to have children are made 1 child at a time until a satisfactory limit is reached. In the pre-planning strategy, a plan is worked out ahead of time and is subsequently carried out. As new reproductive technology is introduced and as progressive change is made in society's reproductive related values and beliefs, choice will continue to dominate chance as the highly likely trend for the future of reproduction. Surrogate maternity is just 1 example of this trend. However, these new options, which culminate in the theory and practice of "progensis," (still in its infancy), as well as offering a rich opportunity, can also incur psychological burdens on a couple. Thus, as with any kind of freedom, these developments will require care, caution and responsibility.

  19. Effects of prior testing lasting a full year in NCANDA adolescents: Contributions from age, sex, socioeconomic status, ethnicity, site, family history of alcohol or drug abuse, and baseline performance

    2017-04-01

    Full Text Available Longitudinal study provides a robust method for tracking developmental trajectories. Yet inherent problems of retesting pose challenges in distinguishing biological developmental change from prior testing experience. We examined factors potentially influencing change scores on 16 neuropsychological test composites over 1 year in 568 adolescents in the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA project. The twice-minus-once-tested method revealed that performance gain was mainly attributable to testing experience (practice with little contribution from predicted developmental effects. Group mean practice slopes for 13 composites indicated that 60% to ∼100% variance was attributable to test experience; General Ability accuracy showed the least practice effect (29%. Lower baseline performance, especially in younger participants, was a strong predictor of greater gain. Contributions from age, sex, ethnicity, examination site, socioeconomic status, or family history of alcohol/substance abuse were nil to small, even where statistically significant. Recognizing that a substantial proportion of change in longitudinal testing, even over 1-year, is attributable to testing experience indicates caution against assuming that performance gain observed during periods of maturation necessarily reflects development. Estimates of testing experience, a form of learning, may be a relevant metric for detecting interim influences, such as alcohol use or traumatic episodes, on behavior.

    The HIV epidemic continues to be a major public health concern, affecting communities with varying prevention and treatment needs. In the U.S., Latino men who have sex with men (MSM) bear a disproportionate burden of HIV incidence. While recent studies have highlighted the relevance of relationship factors for HIV transmission among MSM generally, the unique needs and experiences of Latino MSM have received relatively little attention. Consequently, associations between relationship factors and HIV risk among Latino MSM remain unknown. This mixed-method study examined relationship status and dynamics and potential HIV-related risk behaviors among Latino MSM. Quantitative analyses with 240 Latino MSM investigated associations between relationship status and engagement in condomless anal intercourse (CAI). Focus groups with 20 Latino male couples and 10 health service providers explored the impact of relationship dynamics on sexual behaviors, as well as opportunities to intervene on HIV risk. The majority of participants were predominantly Spanish speaking, most screened positive for high-risk alcohol consumption in the past month, more than half engaged in CAI in the past 3 months, and a majority reported multiple sexual partners in this period. Among participants in same-sex relationships (n = 175), approximately half reported multiple partners in the previous 3 months and more than two-thirds reported CAI in this time period. Being in a same-sex relationship was positively associated with high-risk alcohol consumption and being age 30 or older and negatively associated with having multiple partners. Moreover, being in a same-sex relationship significantly increased the likelihood that participants would report engaging in CAI. Qualitative analyses identified themes related to relationship dynamics and sexual behavior, as well as opportunities to intervene on HIV risk. Despite the challenges encountered by Latino male couples, most participants expressed

  2. Chance and necessity in eye evolution.

    Gehring, Walter J

    2011-01-01

    Charles Darwin has proposed the theory that evolution of live organisms is based on random variation and natural selection. Jacques Monod in his classic book Chance and Necessity, published 40 years ago, presented his thesis "that the biosphere does not contain a predictable class of objects or events, but constitutes a particular occurrence, compatible indeed with the first principles, but not deducible from those principals and therefore, essentially unpredictable." Recent discoveries in eye evolution are in agreement with both of these theses. They confirm Darwin's assumption of a simple eye prototype and lend strong support for the notion of a monophyletic origin of the various eye types. Considering the complexity of the underlying gene regulatory networks the unpredictability is obvious. The evolution of the Hox gene cluster and the specification of the body plan starting from an evolutionary prototype segment is discussed. In the course of evolution, a series of similar prototypic segments gradually undergoes cephalization anteriorly and caudalization posteriorly through diversification of the Hox genes.

  3. Chance and design in proinsecticide discovery.

    2017-04-01

    Many insecticides are inactive on their target sites in the form that is sold and applied, needing first to be bioactivated. This proinsecticide strategy has often been achieved by design, through systematic derivatization of intrinsically active molecules with protecting groups that mask their toxic effects until their selective removal in target insects by metabolic enzymes generates the toxiphore. Proinsecticides can be designed to gain selectivity between target and non-target organisms, or to improve bioavailability by enhancing plant or insect uptake. In most cases, however, chance trumps design in proinsecticide discovery: most first-in-class products that we now know to be proinsecticides were only discovered a posteriori to be such, often after having been on the market for years. Knowing the active form of an insecticide is essential to mode of action identification, and early mode of action studies on novel chemotypes should take into account the possibility that the compounds might be proinsecticides. This paper reviews examples of proinsecticides in the marketplace, strategies for making proinsecticides and techniques for unmasking proinsecticides in mode of action studies. Our analysis of global agrochemical sales data shows that 34% of the dollar value of crop insecticides used in 2015 were proinsecticides. © 2016 Society of Chemical Industry.

  4. Seizure prediction: any better than chance?

    To test whether epileptic seizure prediction algorithms have true predictive power, their performance must be compared with the one expected under well-defined null hypotheses. For this purpose, analytical performance estimates and seizure predictor surrogates were introduced. We here extend the Monte Carlo framework of seizure predictor surrogates by introducing alarm times surrogates. We construct artificial seizure time sequences and artificial seizure predictors to be consistent or inconsistent with various null hypotheses to determine the frequency of null hypothesis rejections obtained from analytical performance estimates and alarm times surrogates under controlled conditions. Compared to analytical performance estimates, alarm times surrogates are more flexible with regard to the testable null hypotheses. Both approaches have similar, high statistical power to indicate true predictive power. For Poisson predictors that fulfill the null hypothesis of analytical performance estimates, the frequency of false positive null hypothesis rejections can exceed the significance level for long mean inter-alarm intervals, revealing an intrinsic bias of these analytical estimates. Alarm times surrogates offer important advantages over analytical performance estimates. The key question in the field of seizure prediction is whether seizures can in principle be predicted or whether algorithms which have been presumed to perform better than chance actually are unable to predict seizures and simply have not yet been tested against the appropriate null hypotheses. Alarm times surrogates can help to answer this question.

  6. Fault system polarity: A matter of chance?

    Many normal fault systems and, on a smaller scale, fracture boudinage exhibit asymmetry so that one fault dip direction dominates. The fraction of throw (or heave) accommodated by faults with the same dip direction in relation to the total fault system throw (or heave) is a quantitative measure of fault system asymmetry and termed 'polarity'. It is a common belief that the formation of domino and shear band boudinage with a monoclinic symmetry requires a component of layer parallel shearing, whereas torn boudins reflect coaxial flow. Moreover, domains of parallel faults are frequently used to infer the presence of a common décollement. Here we show, using Distinct Element Method (DEM) models in which rock is represented by an assemblage of bonded circular particles, that asymmetric fault systems can emerge under symmetric boundary conditions. The pre-requisite for the development of domains of parallel faults is however that the medium surrounding the brittle layer has a very low strength. We demonstrate that, if the 'competence' contrast between the brittle layer and the surrounding material ('jacket', or 'matrix') is high, the fault dip directions and hence fault system polarity can be explained using a random process. The results imply that domains of parallel faults are, for the conditions and properties used in our models, in fact a matter of chance. Our models suggest that domino and shear band boudinage can be an unreliable shear-sense indicator. Moreover, the presence of a décollement should not be inferred on the basis of a domain of parallel faults only.

    Conclusions: These results mirror studies that find interactive toxicity beliefs are a potent predictor of intentional antiretroviral non-adherence among people living with HIV and suggest interactive toxicity beliefs may impede PrEP uptake and adherence. Messages to increase PrEP awareness and adherence may also take steps to counter erroneous beliefs about mixing alcohol with antiretrovirals in the context of PrEP.

    Aims To study the “social brain” in alcoholics by investigating social contract reasoning, theory of mind, and emotional intelligence. Design A behavioral study comparing recently detoxified alcoholics with normal, healthy controls. Setting Emotional intelligence and decoding of emotional non-verbal cues have been shown to be impaired in alcoholics. This study explores whether these deficits extend to conditional reasoning about social contracts. Participants 25 recently detoxified alcoholics (17 men and 8 women) were compared with 25 normal controls (17 men and 8 women) matched for sex, age, and education level. Measurements Wason Selection Task investigating conditional reasoning on three different rule types (social contract, precautionary, and descriptive), Revised Reading the Mind in the Eyes Test, Trait Emotional Intelligence Questionnaire (modified version), and additional control measures. Findings Conditional reasoning was impaired in alcoholics. Performance on descriptive rules was not above chance. Reasoning performance was markedly better on social contract and precautionary rules, but this performance was still significantly lower than in controls. Several emotional intelligence measures were lower in alcoholics compared to controls, but these were not correlated with reasoning performance. Conclusions Conditional reasoning and emotional intelligence appear impaired in alcoholics. Impairment was particularly severe on descriptive rules. Though alcoholics' performance was better on social contract and precautionary rules, overall reasoning performance was still low. Differential performance is consistent with distinct neurocognitive reasoning mechanisms and partial resilience of evolutionarily-relevant functions. Impairment in social contract reasoning might lead to misunderstandings and frustration in social interactions, and reasoning difficulties about precautionary rules might contribute to risky behaviors in this population.

    Full Text Available Aim: To determine the level of alcohol consumption in a selected group of adolescents. Design: A descriptive cross-sectional study. Methods: The data were obtained using a part of the standardized ESPAD questionnaire for assessing consumption of alcoholic beverages. The sample comprised 422 students from seven secondary schools of different types in the city of Ostrava. For statistical analysis, the chi-squared test and Fisher's exact test (for n ≤ 5 were used. The data were processed using Stata v. 10. Results: More than half of respondents first tried alcohol before the age of 15. The most frequent alcohol-related problems were unprotected sex, decreased school performance and problems with parents or friends. Incomplete families were found to be an important factor in adolescents preferring and more frequently drinking beer. Conclusion: The study confirmed results reported by the Europe-wide survey ESPAD, namely that adolescents start to drink alcohol as early as before they turn fifteen.

    This study examined sexual orientation discordance, a mismatch between self-reported sexual identity and sexual behavior or sexual attraction, by describing the characteristics, substance use disorders, and mental health risks of heterosexual identified individuals who endorsed this pattern of sexual identification, behavior, and attraction. Using data from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC), we created three groups based on participants' reported sexual identity and either their sexual behavior or sexual attraction: heterosexual concordant, homosexual concordant, and heterosexual discordant. Bivariate models assessed the relationship of discordant status and demographic correlates, lifetime substance use disorders, and mental health diagnoses. Logistic regression models tested associations between both behavior discordance and attraction discordance and the likelihood of having lifetime disorders of substance use, major depression, and generalized anxiety. Results of this study provided evidence of varying levels of substance use and mental health disorder risk by gender, discordance status, and discordance type. Behavioral discordance was associated with increased risk of mental health and substance use disorder among women (compared to heterosexual concordance). Findings among men were less consistent with heightened risk of alcohol and inhalant use only. Attraction discordance was notably different from behavioral discordance. The odds of substance use and mental health disorders were the same or lower compared with both the heterosexual and homosexual concordance groups. Future research should begin to test theoretical explanations for these differences.

    Background This study aimed to determine between-country differences and changes over time in the portrayal of youth risk behaviors in films rated for youth in Argentina, Brazil, Mexico and the United States. Methods Content and ratings were analyzed for 362 films that were popular across all four countries from 2002–2009. Country-specific ratings were classified as either youth or adult, and Generalized Estimating Equations were used to determine between-country differences in the presence of tobacco, alcohol, drugs, sexual content, and violence in youth-rated films. Within-country differences in this content over time were also assessed, comparing films released from 2002–2005 with those released from 2006–2009. Results In the US, films rated for youth were less likely to contain all five risk behaviors than in youth-rated films in Argentina, Brazil, and, when the “15 and older” rating was considered a youth rating, in Mexico. All three Latin American countries “downrated” films that received an adult rating in the US. Nevertheless, tobacco and drug use in youth-rated films declined over time in all countries, whereas moderate to extreme alcohol use and violence involving children or youth increased in all countries. Conclusions Tobacco and drug use have declined in popular US films, but these behaviors are still prevalent in films rated for youth across the Americas. The apparent success of advocacy efforts to reduce tobacco and other drugs in films suggests that similar efforts be directed to reduce alcohol portrayals. PMID:24316001

    Full Text Available Atherosclerosis is manifested as coronary artery disease (CAD, ischemic stroke and peripheral vascular disease. Moderate alcohol consumption has been associated with reduction of CAD complications. Apparently, red wine offers more benefits than any other kind of drinks, probably due to flavonoids. Alcohol alters lipoproteins and the coagulation system. The flavonoids induce vascular relaxation by mechanisms that are both dependent and independent of nitric oxide, inhibits many of the cellular reactions associated with atherosclerosis and inflammation, such as endothelial expression of vascular adhesion molecules and release of cytokines from polymorphonuclear leukocytes. Hypertension is also influenced by the alcohol intake. Thus, heavy alcohol intake is almost always associated with systemic hypertension, and hence shall be avoided. In individuals that ingest excess alcohol, there is higher risk of coronary occlusion, arrhythmias, hepatic cirrhosis, upper gastrointestinal cancers, fetal alcohol syndrome, murders, sex crimes, traffic and industrial accidents, robberies, and psychosis. Alcohol is no treatment for atherosclerosis; but it doesn't need to be prohibited for everyone. Thus moderate amounts of alcohol (1-2 drinks/day, especially red wine, may be allowed for those at risk for atherosclerosis complications.

  3. Stochastic Water Quality Optimization Using Imbedded Chance Constraints

    Science.gov (United States)

    Ellis, J. Hugh

    1987-12-01

    A chance-constrained stochastic programming model is developed for water quality optimization. It determines the least cost allocation of waste treatment plant biochemical oxygen demand (BOD) removal efficiencies, subject to probabilistic restrictions on maximum allowable instream dissolved oxygen deficit. The new model extends well beyond traditional approaches that assume streamflow is the sole random variable. In addition to streamflow, other random variables in the model are initial in-stream BOD level and dissolved oxygen (DO) deficit; waste outfall flow rates, BOD levels and DO deficits; deoxygenation k1, reaeration k2, and sedimentation-scour rate k3 coefficients of the Streeter-Phelps DO sag model; photosynthetic input-benthic depletion rates Ai, and nonpoint source BOD input rate Pi for the Camp-Dobbins extensions to the Streeter-Phelps model. These random variables appear in more highly aggregated terms which in turn form part of the probabilistic constraints of the water quality optimization model. Stochastic simulation procedures for estimating the probability density functions and covariances of these aggregated terms are discussed. A new chance-constrained programming variant, imbedded chance constraints, is presented along with an example application. In effect, this method imbeds a chance constraint within a chance constraint in a manner which is loosely associated with the distribution-free method of chance-constrained programming. It permits the selection of nonexpected value realizations of the mean and variance estimates employed in the deterministic equivalents of traditional chance-constrained models. As well, it provides a convenient mechanism for generating constraint probability response surfaces. A joint chance-constrained formulation is also presented which illustrates the possibility for prescription of an overall system reliability level, rather than reach-by-reach reliability assignment.

    This article provides information on the amount of alcohol consumed by students during college sports events. It examines the relationship between alcohol consumption and the rank of the match, sex of the players (male vs. female league), and sex of the spectators. The study was carried out during an interdepartmental volleyball championship (cup system) at the University of Warmia and Mazury in Olsztyn (Poland), which included 16 matches (in both male and female leagues). The research sample consisted of 2,683 students between ages 19 and 24 years (including 1,768 men and 915 women) who came to cheer on their peers at the matches. Two objective measurements of alcohol consumption were used: (a) the number of empty alcohol packages left behind by the spectators at the sports facilities after each match and (b) breath alcohol analysis tests given to volunteering spectators after each match (in which 323 persons consented to participate). Male league games were accompanied by more alcohol consumption than were female league games, and male spectators drank more than female spectators. The most drinking occurred among men watching the male league, and the least amount of drinking occurred among women watching the female league. Alcohol intoxication increased with the rank of the match mostly among men watching the male league. The sex of players and spectators seems to be a mediating factor in the relationship between the rank of a match and the amount of alcohol consumed.

    Ban, Deokjin

    2011-06-30

    In Classical Greece, works defining the nature of art appeared in the various disciplines like medicine, rhetoric, dietetics, architecture and painting. Hippocratic authors tried to show that an art of medicine existed indeed. They contrasted the concept of art with that of chance, not experience that Plato and Aristotle distinguished from art. In fact there are similarities and discrepancies between Hippocratic epistemology and Platoic epistemology. Hippocratic authors maintained that the products of chance were not captured by art. They distinguished the domain of art charactered by explanatory knowledge and prediction from the domain of chance ruled by the unexplained and the unforeseeable. They minimized the role of luck and believed the role of art. Hippocratic authors thought that professional ability contained both knowledge and experience. In Hippocratic corpus, experience is a synonym of competence and usually has a positive meaning. But Plato gave empirical knowledge the disdainful sense and decided a ranking between two types of knowledge. Both Hippocratic authors and Plato held that a genuine art had connection with explanatory knowledge of the nature of its subject matter. A common theme that goes through arguments about art-chance and art-chance is the connection between art and nature. Hippocratic authors and Plato regarded art as a highly systematic process. Art provides us with general and explanatory knowledge of human nature. Art and nature is a mutual relationship. The systematic understanding of nature helps us gain the exactness of art and an exact art helps us understand nature well.

  10. Efficient relaxations for joint chance constrained AC optimal power flow

    Energy Technology Data Exchange (ETDEWEB)

    Baker, Kyri; Toomey, Bridget

    2017-07-01

    Evolving power systems with increasing levels of stochasticity call for a need to solve optimal power flow problems with large quantities of random variables. Weather forecasts, electricity prices, and shifting load patterns introduce higher levels of uncertainty and can yield optimization problems that are difficult to solve in an efficient manner. Solution methods for single chance constraints in optimal power flow problems have been considered in the literature, ensuring single constraints are satisfied with a prescribed probability; however, joint chance constraints, ensuring multiple constraints are simultaneously satisfied, have predominantly been solved via scenario-based approaches or by utilizing Boole's inequality as an upper bound. In this paper, joint chance constraints are used to solve an AC optimal power flow problem while preventing overvoltages in distribution grids under high penetrations of photovoltaic systems. A tighter version of Boole's inequality is derived and used to provide a new upper bound on the joint chance constraint, and simulation results are shown demonstrating the benefit of the proposed upper bound. The new framework allows for a less conservative and more computationally efficient solution to considering joint chance constraints, specifically regarding preventing overvoltages.

  12. Randomized Solutions to Convex Programs with Multiple Chance Constraints

    CERN Document Server

    Schildbach, Georg; Morari, Manfred

    2012-01-01

    Optimization is ubiquitous in modern problems of engineering and science, and in many cases it comes along with some uncertainty about the system or model underlying the problem at hand. A large variety of approaches for handling uncertainty have been proposed in the areas of robust and stochastic optimization, of which the formulation of chance-constraints has proven to be an appropriate concept for many practical applications. Yet chance-constrained optimization programs are generally difficult to solve. The scenario approach provides an intuitive way of approximating the solution to chance-constrained optimization programs, based on finding an optimal solution under a finite number of sampled outcomes of the uncertainty (`scenarios'). A key merit of this approach is that it neither requires knowledge of an uncertainty set, as it is common in robust optimization, nor of a probability distribution, as it is usually assumed in stochastic optimization. Recent research has obtained a strong theoretical foundati...

  13. Accounting for chance in the calculus of autoimmune disease.

    Science.gov (United States)

    Moore, Daniel J

    2010-02-01

    Discussions around the etiology of autoimmune disease routinely focus on the interplay between genes and the environment. In turn, efforts to ameliorate these diseases seek to modify genetic and environmental factors. However, there may be a third element that also accounts for the progression of autoimmunity. This article explores the role of chance, exemplified by the stochastic process of immune repertoire generation, in the evolution of autoimmunity. The presented modeling studies and concepts suggest that chance plays as significant a role as genes or environment. This hypothesis implies that a full understanding of the role of genes and environment will also require investigators to account for stochastic processes in building comprehensive disease models.

    Full Text Available It is assumed that medical guidelines specify the appropriate amount of a divisible good which each individual should receive. Individual requirements and probabilities that the treatment is successful if an appropriate amount is received differ. The same applies to the success probabilities if individuals are inadequately treated. If supply is insufficient to serve all with appropriate amounts an allocation decision is necessary. We define probabilistic allocation rules that allocate chances of successful treatment to all individuals. We analyse a specific random allocation rule that assigns maximal equal gains of chances. We characterize the equal gain rule axiomatically.

    the third grade of secondary education, selected by two-stage cluster sampling, defined by the socioeconomic characteristics of the neighborhood in which each school is located and by school class. Data collection was by means of a questionnaire which was completed anonymously and voluntarily. RESULTS: Fifty-four percent of the older adolescent boys (aged 14-19 drank alcohol, compared to 17% of the younger adolescent boys (10-13, as did 58% of the older adolescent girls and 19% of the younger adolescent girls. Fifty-seven percent of the students had suffered severe victimization, and 53% had suffered moderate victimization. When the samples were separated by sex, it was observed that boys and girls who drank alcohol reported 2.6 and 1.8 times more severe victimization respectively, while alcohol was associated with 3.1 and 2.5 times greater prevalence of moderate victimization, among boys and girls respectively. When episodes of drunkenness were analyzed, it was observed that adolescents got drunk more than pre-adolescents and that exposure to violence exhibited an increased association with drunkenness. Thirty-two percent of the boys (prevalence ratio, PR = 4.4; 95%CI 2.6-7.3 and 22% of the girls (PR = 2.2; 95%CI 1.2-4.1 who had been the victims of severe violence reported being drunk at least once. CONCLUSIONS: Adolescents of both sexes who consume more alcohol are at greater risk of suffering community violence.

  1. Inequality of Chances as a Symmetry Phase Transition

    Directory of Open Access Journals (Sweden)

    Jorge Rosenblatt

    2013-05-01

    Full Text Available We propose a model for Lorenz curves. It provides two-parameter fits to data on incomes, electric consumption, life expectation and rate of survival after cancer. Graphs result from the condition of maximum entropy and from the symmetry of statistical distributions. Differences in populations composing a binary system (poor and rich, young and old, etc. bring about chance inequality. Symmetrical distributions insure equality of chances, generate Gini coefficients Gi £ ⅓, and imply that nobody gets more than twice the per capita benefit. Graphs generated by different symmetric distributions, but having the same Gini coefficient, intersect an even number of times. The change toward asymmetric distributions follows the pattern set by second-order phase transitions in physics, in particular universality: Lorenz plots reduce to a single universal curve after normalisation and scaling. The order parameter is the difference between cumulated benefit fractions for equal and unequal chances. The model also introduces new parameters: a cohesion range describing the extent of apparent equality in an unequal society, a poor-rich asymmetry parameter, and a new Gini-like indicator that measures unequal-chance inequality and admits a theoretical expression in closed form.

    Full Text Available Increasing life expectancy (LE raises expectations for social participation at later ages. We computed health expectancies (HE to assess the (unequal chances of social/work participation after age 50 in the context of France in 2003. We considered five HEs, covering various health situations which can jeopardize participation, and focused on both older ages and the pre-retirement period. HEs reveal large inequalities for both sexes in the chances of remaining healthy after retirement, and also of reaching retirement age in good health and without disability, especially in low-qualified occupations. These results challenge the policy expectation of an overall increase in social participation at later ages.

  18. Chance-Constrained Guidance With Non-Convex Constraints

    Science.gov (United States)

    Ono, Masahiro

    2011-01-01

    Missions to small bodies, such as comets or asteroids, require autonomous guidance for descent to these small bodies. Such guidance is made challenging by uncertainty in the position and velocity of the spacecraft, as well as the uncertainty in the gravitational field around the small body. In addition, the requirement to avoid collision with the asteroid represents a non-convex constraint that means finding the optimal guidance trajectory, in general, is intractable. In this innovation, a new approach is proposed for chance-constrained optimal guidance with non-convex constraints. Chance-constrained guidance takes into account uncertainty so that the probability of collision is below a specified threshold. In this approach, a new bounding method has been developed to obtain a set of decomposed chance constraints that is a sufficient condition of the original chance constraint. The decomposition of the chance constraint enables its efficient evaluation, as well as the application of the branch and bound method. Branch and bound enables non-convex problems to be solved efficiently to global optimality. Considering the problem of finite-horizon robust optimal control of dynamic systems under Gaussian-distributed stochastic uncertainty, with state and control constraints, a discrete-time, continuous-state linear dynamics model is assumed. Gaussian-distributed stochastic uncertainty is a more natural model for exogenous disturbances such as wind gusts and turbulence than the previously studied set-bounded models. However, with stochastic uncertainty, it is often impossible to guarantee that state constraints are satisfied, because there is typically a non-zero probability of having a disturbance that is large enough to push the state out of the feasible region. An effective framework to address robustness with stochastic uncertainty is optimization with chance constraints. These require that the probability of violating the state constraints (i.e., the probability of

    Alcohol use is a known key risk factor associated with risky sexual behavior that contributes to HIV transmission. This cross-sectional study used time location sampling to investigate alcohol use and risky sexual behaviors that occurred after ingesting alcohol among 609 patrons of alcohol venues in Gaborone, Botswana. Alcohol Use Disorders Identification Test (AUDIT) scores were categorized as low (1-7), medium (8-15), and high (16+) for analysis. Logistic regression models stratified by gender assessed the association between alcohol use and condom use at last sex after drinking alcohol. Among females, the odds of condom use during last sex after drinking alcohol were significantly lower for high compared to low AUDIT scores (AOR = 0.17, 95% CI 0.06-0.54). Among males, factors significantly associated with condom use at last sex after alcohol use were low levels of education (primary level compared to university and above AOR = 0.13; 95% CI 0.03-0.55) and beliefs that alcohol use did not increase risky sexual behaviors (AOR = 0.26; 95% CI 0.11-0.62). HIV prevention interventions should target females and emphasize sexual risks associated with alcohol use.

  5. Beyond chance? The persistence of performance in online poker.

    Directory of Open Access Journals (Sweden)

    Rogier J D Potter van Loon

    Full Text Available A major issue in the widespread controversy about the legality of poker and the appropriate taxation of winnings is whether poker should be considered a game of skill or a game of chance. To inform this debate we present an analysis into the role of skill in the performance of online poker players, using a large database with hundreds of millions of player-hand observations from real money ring games at three different stakes levels. We find that players whose earlier profitability was in the top (bottom deciles perform better (worse and are substantially more likely to end up in the top (bottom performance deciles of the following time period. Regression analyses of performance on historical performance and other skill-related proxies provide further evidence for persistence and predictability. Simulations point out that skill dominates chance when performance is measured over 1,500 or more hands of play.

    William R. Francis and Bassam El-Effendi shared a common ground: they were the first individuals to classify Hangman's Fractures. Interestingly, although they were unaware of each other, they classified and published their findings in the same year, published in the same edition of the same journal (but on different pages). This new classification system was a chance for notoriety for El-Effendi, yet it was a misfortune for Francis. Both physicians graduated in 1973 (from different universities). Also fellows at different universities in 1981, they were also both unaware they studied the same topic. Coincidentally, their paths crossed in the same edition of a journal where their studies were published in the same year, which was unprecedented in the literature. One classification scheme is well-known while the other is almost completely unheard of for no apparent reason other than chance for one and misfortune for the other.

  7. Alcohol and suicide: neurobiological and clinical aspects.

    2006-06-21

    Alcohol, primarily in the form of ethyl alcohol (ethanol), has occupied an important place in the history of humankind for at least 8,000 years. In most Western societies, at least 90% of people consume alcohol at some time during their lives, and 30% or more of drinkers develop alcohol-related problems. Severe alcohol-related life impairment, alcohol dependence (alcoholism), is observed at some time during their lives in about 10% of men and 3-5% of women. An additional 5-10% of each sex develops persistent, but less intense, problems that are diagnosed as alcohol abuse. It this review, neurobiological aspects of suicidal behavior in alcoholism is discussed. In individuals with comorbid depression and alcoholism, greater serotonergic impairment may be associated with higher risk of completed suicide. Dopaminergic dysfunction may play an important role in the pathophysiology of suicidal behavior in alcoholism. Brain damage and neurobehavioral deficits are associated with alcohol use disorders and may contribute to suicidal behavior in persons with alcohol dependence or abuse. Aggression/impulsivity and alcoholism severity affect risk for suicide among individuals with alcoholism. Major depressive episodes and stressful life events particularly, partner-relationship disruptions, may precipitate suicidal behavior in individuals with alcohol use disorders. Alcohol misuse and psychosocial adversity can combine to increase stress on the person, and, thereby, potentially, increase the risk for suicidal behavior. The management of suicidal patients with alcohol use disorders is also discussed. It is to be hoped that the efforts of clinicians will reduce morbidity and mortality associated with alcohol misuse.

    Alcohol is the most frequently consumed toxic substance in the world. Low to moderate daily intake of alcohol has been shown to have beneficial effects on the cardiovascular system. In contrast, exposure to high levels of alcohol for a long period could lead to progressive cardiac dysfunction and heart failure. Cardiac dysfunction associated with chronic and excessive alcohol intake is a specific cardiac disease known as alcoholic cardiomyopathy(ACM). In spite of its clinical importance, data on ACM and how alcohol damages the heart are limited. In this review, we evaluate available evidence linking excessive alcohol consumption with heart failure and dilated cardiomyopathy. Additionally, we discuss the clinical presentation, prognosis and treatment of ACM.

Games of chance have always been useful random experiments which through combinatorial calculation have opened the way to probability theory and to the interpretation of modern science through statistical laws. The article also looks briefly at the stormy nineteenth-century debate concerning the definitions of probability which went over the same grounds – sometimes without any historical awareness – as the debate which arose at the very beginnings of probability theory, when the great probability theorists were open to every possible meaning of the term.

    2017-01-01

    The letters transcribed in this book were written by physicist David Bohm to three close female acquaintances in the period 1950 to 1956. They provide a background to his causal interpretation of quantum mechanics and the Marxist philosophy that inspired his scientific work in quantum theory, probability and statistical mechanics. In his letters, Bohm reveals the ideas that led to his ground breaking book Causality and Chance in Modern Physics. The political arguments as well as the acute personal problems contained in these letters help to give a rounded, human picture of this leading scientist and twentieth century thinker.

    Full Text Available Introduction: We examine the association between self-reported alcohol misuse and alcohol usewithin 2 hours of having sex and the number of sexual partners among a sample of African-Americanand Latino emergency department (ED patients.Methods: Cross-sectional data were collected prospectively from a randomized sample of all EDpatients during a 5-week period. In face-to-face interviews, subjects were asked to report their alcoholuse and number of sexual partners in the past 12 months. Data were analyzed using multiple variablenegative binomial regression models, and effect modification was assessed through inclusion ofinteraction terms.Results: The 395 study participants reported an average of 1.4 (standard error¼0.11 sexual partnersin the past 12 months, 23% reported misusing alcohol, and 28% reported consuming alcohol beforesex. There was no statistically significant association between alcohol misuse and the number ofsexual partners; however, alcohol before sex was associated with a larger number of sexual partners inthe past year. Moreover, among those who misused alcohol, participants who reported alcohol beforesex were 3 times more likely to report a higher number of sexual partners (risk ratio¼3.2; confidenceinterval [CI]¼1.9–5.6. The association between alcohol use before sex and number of sexual partnersis dependent upon whether a person has attributes of harmful drinking over the past 12 months.Overall, alcohol use before sex increases the number of sexual partners, but the magnitude of thiseffect is significantly increased among alcohol misusers.Conclusion: Alcohol misusers and those who reported having more than 1 sexual partner were morelikely to cluster in the same group, ie, those who used alcohol before sex. Efforts to reduce the burdenof sexually transmitted diseases, including human immunodeficiency virus, and other consequences ofrisky sexual behavior in the ED population should be cognizant of the interplay of alcohol and

    The average US adolescent is exposed to 34 references to alcohol in popular music daily. Although brand recognition is an independent, potent risk factor for alcohol outcomes among adolescents, alcohol brand appearances in popular music have not been assessed systematically. We aimed to determine the prevalence of and contextual elements associated with alcohol brand appearances in US popular music. Qualitative content analysis. We used Billboard Magazine to identify songs to which US adolescents were most exposed in 2005-07. For each of the 793 songs, two trained coders analyzed independently the lyrics of each song for references to alcohol and alcohol brand appearances. Subsequent in-depth assessments utilized Atlas.ti to determine contextual factors associated with each of the alcohol brand appearances. Our final code book contained 27 relevant codes representing six categories: alcohol types, consequences, emotional states, activities, status and objects. Average inter-rater reliability was high (κ = 0.80), and all differences were easily adjudicated. Of the 793 songs in our sample, 169 (21.3%) referred explicitly to alcohol, and of those, 41 (24.3%) contained an alcohol brand appearance. Consequences associated with alcohol were more often positive than negative (41.5% versus 17.1%, P brand appearances were associated commonly with wealth (63.4%), sex (58.5%), luxury objects (51.2%), partying (48.8%), other drugs (43.9%) and vehicles (39.0%). One in five songs sampled from US popular music had explicit references to alcohol, and one-quarter of these mentioned a specific alcohol brand. These alcohol brand appearances are associated commonly with a luxury life-style characterized by wealth, sex, partying and other drugs. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    Alcohol use and alcohol-related problems are on the rise in low- and middle-income countries. Expenditure on alcohol is an important problem for families and communities and needs to be assessed. This study examines level of alcohol consumption and expenditure on alcohol in a district in Vietnam. A cross-sectional survey was conducted in a rural district in northern Vietnam. Multi-stage sampling was employed to randomly select participants from 20 communities and a town in the same district. One thousand five hundred and sixty-four adults (765 males and 799 females) aged 18-60 years were interviewed. Information about alcohol use as well as expenditure on alcohol consumption four weeks prior to the interview was gathered. Non-parametric tests and log-linear regression were employed to compare expenditure on alcohol consumption across socioeconomic groups. The prevalence of alcohol use one month prior to interview was 35% (66% among men and 5% among women). The median alcohol consumption among those who reported use of alcohol in the week prior to the interview was 7.9 standard drinks. Excessive drinking (more than 14 standard drinks per week for men and more than seven standard drinks per week for women) occurred among 35% of those who used alcohol. Median expenditure for alcohol consumption during one month by those who drank alcohol was USD 3.5, accounting for 4.6% of household food expenditure, 2.7% of total household expenditure, and 1.8% of household income. The differences in alcohol consumption and expenditure between sexes and between socioeconomic groups are also presented. Our study confirms that alcohol consumption and alcohol-related problems are common among men in Vietnam. The share of alcohol expenditure in total household expenditure is substantial, especially among poor households. This should be considered an important public health issue, which needs to be taken into account in the alcohol policy debate.

  10. Bilevel Fuzzy Chance Constrained Hospital Outpatient Appointment Scheduling Model

    Directory of Open Access Journals (Sweden)

    Xiaoyang Zhou

    2016-01-01

    Full Text Available Hospital outpatient departments operate by selling fixed period appointments for different treatments. The challenge being faced is to improve profit by determining the mix of full time and part time doctors and allocating appointments (which involves scheduling a combination of doctors, patients, and treatments to a time period in a department optimally. In this paper, a bilevel fuzzy chance constrained model is developed to solve the hospital outpatient appointment scheduling problem based on revenue management. In the model, the hospital, the leader in the hierarchy, decides the mix of the hired full time and part time doctors to maximize the total profit; each department, the follower in the hierarchy, makes the decision of the appointment scheduling to maximize its own profit while simultaneously minimizing surplus capacity. Doctor wage and demand are considered as fuzzy variables to better describe the real-life situation. Then we use chance operator to handle the model with fuzzy parameters and equivalently transform the appointment scheduling model into a crisp model. Moreover, interactive algorithm based on satisfaction is employed to convert the bilevel programming into a single level programming, in order to make it solvable. Finally, the numerical experiments were executed to demonstrate the efficiency and effectiveness of the proposed approaches.

  11. Entrepreneurs, chance, and the deterministic concentration of wealth.

    Directory of Open Access Journals (Sweden)

    Joseph E Fargione

    Full Text Available In many economies, wealth is strikingly concentrated. Entrepreneurs--individuals with ownership in for-profit enterprises--comprise a large portion of the wealthiest individuals, and their behavior may help explain patterns in the national distribution of wealth. Entrepreneurs are less diversified and more heavily invested in their own companies than is commonly assumed in economic models. We present an intentionally simplified individual-based model of wealth generation among entrepreneurs to assess the role of chance and determinism in the distribution of wealth. We demonstrate that chance alone, combined with the deterministic effects of compounding returns, can lead to unlimited concentration of wealth, such that the percentage of all wealth owned by a few entrepreneurs eventually approaches 100%. Specifically, concentration of wealth results when the rate of return on investment varies by entrepreneur and by time. This result is robust to inclusion of realities such as differing skill among entrepreneurs. The most likely overall growth rate of the economy decreases as businesses become less diverse, suggesting that high concentrations of wealth may adversely affect a country's economic growth. We show that a tax on large inherited fortunes, applied to a small portion of the most fortunate in the population, can efficiently arrest the concentration of wealth at intermediate levels.

    1992-05-01

    Topographic measures of electroencephalographic (EEG) amplitude were used to compare recovered alcoholics (n = 14) with sex- and age-matched control subjects. Delta, alpha, and beta activity did not distinguish the groups, but regional differences in theta distribution did. Recovered alcoholics showed more uniform distributions of theta amplitudes in bilateral anterior and posterior regions compared with controls. Because a minimum of 5 years had elapsed since the recovered alcoholic subjects fulfilled DSM-III-R criteria for alcohol abuse or dependence, it is unlikely these EEG theta differences reflect the effects of withdrawal.

  15. Chances, risks and limitations of neoadjuvant therapy in surgical oncology

    Directory of Open Access Journals (Sweden)

    Lordick Florian

    2016-09-01

    Full Text Available Over the last decades, neoadjuvant treatment has been established as a standard of care for a variety of tumor types in visceral oncology. Neoadjuvant treatment is recommended in locally advanced esophageal and gastric cancer as well as in rectal cancer. In borderline resectable pancreatic cancer, neoadjuvant therapy is an emerging treatment concept, whereas in resectable colorectal liver metastases, neoadjuvant treatment is often used, although the evidence for improvement of survival outcomes is rather weak. What makes neoadjuvant treatment attractive from a surgical oncology viewpoint is its ability to shrink tumors to a smaller size and to increase the chances for complete resection with clear surgical margins, which is a prerequisite for cure. Studies suggest that local tumor control is increased in some visceral tumor types, especially with neoadjuvant chemoradiotherapy. In some other studies, a better control of systemic disease has contributed to significantly improved survival rates. Additionally, delaying surgery offers the chance to bring the patient into a better general condition for major surgery, but it also confers the risk of progression. Although it is a relatively rare event, cancers may progress locally during neoadjuvant treatment or distant metastases may occur, jeopardizing a curative surgical treatment approach. Although this is seen as risk of neoadjuvant treatment, it can also be seen as a chance to select only those patients for surgery who have a better control of systemic disease. Some studies showed increased perioperative morbidity in patients who underwent neoadjuvant treatment, which is another potential disadvantage. Optimal multidisciplinary teamwork is key to controlling that risk. Meanwhile, the neoadjuvant treatment period is also used as a “window of opportunity” for studying the activity of novel drugs and for investigating predictive and prognostic biomarkers of chemoradiotherapy and radiochemotherapy

  16. Exceeding chance level by chance: The caveat of theoretical chance levels in brain signal classification and statistical assessment of decoding accuracy.

    Science.gov (United States)

    Combrisson, Etienne; Jerbi, Karim

    2015-07-30

    Machine learning techniques are increasingly used in neuroscience to classify brain signals. Decoding performance is reflected by how much the classification results depart from the rate achieved by purely random classification. In a 2-class or 4-class classification problem, the chance levels are thus 50% or 25% respectively. However, such thresholds hold for an infinite number of data samples but not for small data sets. While this limitation is widely recognized in the machine learning field, it is unfortunately sometimes still overlooked or ignored in the emerging field of brain signal classification. Incidentally, this field is often faced with the difficulty of low sample size. In this study we demonstrate how applying signal classification to Gaussian random signals can yield decoding accuracies of up to 70% or higher in two-class decoding with small sample sets. Most importantly, we provide a thorough quantification of the severity and the parameters affecting this limitation using simulations in which we manipulate sample size, class number, cross-validation parameters (k-fold, leave-one-out and repetition number) and classifier type (Linear-Discriminant Analysis, Naïve Bayesian and Support Vector Machine). In addition to raising a red flag of caution, we illustrate the use of analytical and empirical solutions (binomial formula and permutation tests) that tackle the problem by providing statistical significance levels (p-values) for the decoding accuracy, taking sample size into account. Finally, we illustrate the relevance of our simulations and statistical tests on real brain data by assessing noise-level classifications in Magnetoencephalography (MEG) and intracranial EEG (iEEG) baseline recordings.

    to determine the chances of discharge of forensic psychiatric patients (section 63 of the German Legal Code) diagnosed with comorbid psychiatric and somatic disorders. N = 364 patients were evaluated. Diagnostic groups were compared with regard to types and frequencies of comorbid diagnoses, and treatment duration. Both personality disorders as main diagnoses and comorbid personality disorders were associated with prolonged inpatient treatment. Substance dependence in addition to a personality disorder was an aggravating factor. Comorbid somatic disorders affected treatment duration of patients diagnosed with a psychotic disorder. Somatic comorbidity may negatively interact with the treatment of psychiatric problems in schizophrenic patients and thus affect the prospects of discharge in this patient group. © Georg Thieme Verlag KG Stuttgart · New York.

    We describe a gang violence intervention and define targets for prevention. At-risk youths were identified through courts, public schools, and law enforcement regarding gang-related activities. They participated in "A Second's Chance," a true-to-life mock emergency department resuscitation and death of a gang member provided over an 18-month period. A questionnaire was completed by each participant. Forty-nine youths identified as at risk for gang involvement participated (37 male and 12 female, P Gang violence prevention should be channeled through maternal family members. History of incarcerated relatives, acquaintances, and neighborhood exposure to drugs and crime may represent additional risk factors for gang-related involvement. Demonstrations of gang violence scenarios raise awareness to consequences of gang-related activities. Family and neighborhood characteristics should be included in development of intervention scenarios.

    Full Text Available Oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. The various type of oral sex practices are fellatio, cunnilingus and analingus. Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

    Full Text Available Alcohol liver disease is damage to the Liver and its function due to alcohol abuse. It occurs after years of heavy drinking and by through which cirrhosis can occur and which leads to the final phase of Alcoholic liver disease. It not only occurs in heavy drinkers but also there is a chance of getting liver disease go up the longer of been drinking and more alcohol consumption. A study was observational, prospective and descriptive; and was carried out one hundred and nine patients [n=109] who were with suffering from an Alcoholic liver disease, to determine the alcohol withdrawal score and there symptoms involved after they were kept on alcohol withdrawal therapy. An observational, prospective and randomized study was conducted in the hospital from March 2014-March 2016. Questionnaire based session with 10 scaled questions were framed according to CIWA (assessment and management of alcohol withdrawal and the score was noted with their symptoms occurrence after the alcohol cessation plan. CIWA score with moderate severity were found to be highest. 7 patients out of 33 patients in severe category of CIWA score were admitted in the hospital with alcohol withdrawal syndrome and psychological disturbances. Clinical Institute Withdrawal Assessment of Alcohol Scale (CIWA helps clinicians assess and treat potential alcohol withdrawal.

    Full Text Available Abstract Background The proportion of patients who undergo surgery within a clinically safe time is an important performance indicator in health systems that use wait lists to manage access to care. However, little is known about chances of on-time surgery according to variations in existing demand. We sought to determine what proportion of patients have had late coronary bypass surgery after registration on wait lists of different size in a network of hospitals with uniform standards for timing of surgery. Methods Using records from a population-based registry, we studied wait-list times prospectively collected in a cohort of patients registered on wait lists for coronary artery bypass grafting procedures. We compared the number of weeks from registration to surgery against target access times established for three urgency groups. The chances of undergoing surgery within target time have been evaluated in relation to wait-list size at registration and the number of surgeries performed without registration on a wait list. Results In 1991–2001, two in three patients were at risk of late surgery when registered on wait lists for isolated coronary bypass procedures in British Columbia, Canada. Although urgent patients had never seen a wait list with clearance time exceeding one week, the odds of on-time surgery were reduced by 25%, odds ratio [OR] = 0.75 (95% confidence interval [CI] 0.65–0.87 for every additional operation performed without registration on a list. When the wait list at registration required a clearance time of over one month, semi-urgent patients had 51% lower odds of on-time surgery as compared to lists with clearance time less than one week, OR = 0.49 (95%CI 0.41–0.60, after adjustment for age, sex, comorbidity, calendar period, hospital and week on the list. In the non-urgent group, the odds were 69% lower, OR = 0.31 (95%CI 0.20–0.47. Every time an operation in the same hospital was performed without registration on a

    In the present work we studied the effects of four alcoholic beverages on blood alcohol levels, plasma insulin concentrations and plasma glucose concentrations in men and women. The volunteers were healthy non-smokers and they were divided according to sex into two groups of ten individuals. The alcoholic beverages used in the study were beer, red wine, whisky and "cachaça". In men, ingestion of the distilled drinks promoted a spike in blood alcohol levels more quickly than ingestion of the fermented drinks. In women, beer promoted the lowest blood alcohol levels over the 6h of the experiment. Whisky promoted highest blood alcohol levels in both sexes. The ingestion of wine promoted a significant difference in relation to the blood alcohol concentration (BAC) as a function of gender. The ingestion of cachaça by women produced BAC levels significantly smaller than those obtained for wine.

    This study was to explore the prevalence of alcohol experiences and to identify the expectancy on the effects of alcohol and alcohol knowledge in early adolescents. The cross-sectional survey of 1854 students from seven middle schools in one district of Seoul was conducted by convenience sampling. Alcohol experience and early onset of alcohol use were measured by the Youth Risk Behavior Survey. Alcohol expectancy was measured by an Alcohol Effects Questionnaire. Over sixty five percent of adolescents reported that they had previous drinking experiences. The participants with no alcohol drinking experience had a lower level of alcohol knowledge than those with experience(t=2.73, p=.007). In expectancy on effects of alcohol, girls had a more positive alcohol expectation than boys(t=-2.54, p=.011). Alcohol knowledge negatively correlated with alcohol expectancy(r=-.40 p=.000). In regression of alcohol expectancy, gender and alcohol knowledge were significant predictors explaining 17%. The results support that alcohol expectancy is an important link with early drinking experiences and alcohol knowledge, focusing on the importance of gender differences. Therefore, an alcohol prevention program in early adolescence is needed and should be focused on multidimensionality of the alcohol expectancy with developmental and psychosocial factors for early adolescents.

  10. The science of healthy aging: genes, milieu, and chance.

    Science.gov (United States)

    Rattan, Suresh I S

    2007-10-01

    Healthy aging and longevity depend on successful and dynamic interactions among biological, psychological, and environmental factors. Biological aging occurs mainly during the period of survival beyond the evolutionarily required essential lifespan (ELS). Natural selection processes for survival and successful reproduction have selected for a range of genetically determined ELS-assuring maintenance and repair systems (MRSs). The progressive failure of MRSs, and the consequent accumulation of molecular heterogeneity and damage, underlie the biological basis of aging, age-related diseases, and eventual death. However, the genetic processes of MRSs operate in a complex hierarchy of factors which range from intracellular molecular factors to physiological, psychological, environmental, and other stochastic factors, including chance. This view also facilitates setting up a framework for understanding, researching, and developing effective and realistic strategies for aging intervention, prevention, and therapies. Manipulating genes and the milieu in which genes and gene products operate opens up novel possibilities of aging intervention and prevention. Gene therapy, stem cells, and modulation through functional foods, nutriceuticals, cosmeceuticals and lifestyle alterations, including mild stress-induced hormesis, are examples of such strategies at various levels of development and practice.

    Full Text Available Geographical teaching has a long tradition in Cluj-Napoca. There are many fields of study at the Faculty of Geography from Cluj-Napoca, which has separated from a larger faculty in 1994, such is Hydrology – Meteorology. It first appeared in 2006, and already has five generations of students. The enquiry made at eight institutions between 1972 and 2013 shows that students’ penetration inside meteorological and hydrological institutions was a good one. A big part of these students come from the Geography field of study, which has a long tradition, and from the new field – Hydro-Meteorology. It can be observed a pronounced increase of employment since 1999. The biggest chances in obtaining a job in this field appear three years after the graduation. Many specialists finished their Geography studies after obtaining the job. Most of our students work as hydrologist or meteorologist, but also in other jobs, a great number belonging to those working in leadership positions. From this enquiry it can be observed that the field of Hydrology – Meteorology was an appropriate one, succeeding to fulfil its purpose.

  13. Age at Arrival and Life Chances Among Childhood Immigrants.

    2017-02-01

    This study examines the causal relationship between childhood immigrants' age at arrival and their life chances as adults. I analyze panel data on siblings from Norwegian administrative registries, which enables me to disentangle the effect of age at arrival on adult socioeconomic outcomes from all fixed family-level conditions and endowments shared by siblings. Results from sibling fixed-effects models reveal a progressively stronger adverse influence of immigration at later stages of childhood on completed education, employment, adult earnings, occupational attainment, and social welfare assistance. The persistence of these relationships within families indicates that experiences related to the timing of childhood immigration have causal effects on later-life outcomes. These age-at-arrival effects are considerably stronger among children who arrive from geographically distant and economically less-developed origin regions than among children originating from developed countries. The age-at-arrival effects vary less by parental education and child gender. On the whole, the findings indicate that childhood immigration after an early-life formative period tends to constrain later human capital formation and economic opportunities over the life course.

    2011-03-01

    Asphyxiophilic sex is a form of autoerotic activity, in which the user creates mechanical means (such as hanging or bondage) in order to achieve cerebral hypoxia, which, in turn, enhances sexual, as well as orgasmic, stimulus. Failure of safety mechanisms, created by the user, may lead to instant death as a result of asphyxiation or strangulation. This kind of sexual practice is more prevalent among men than in women. In cases of death, it is difficult to relate it to the sexual practice itself. Suicide and homicide are the main differential diagnoses. Closely related derivatives of asphyxiophilic sex are anesthesiophilia (inhalation of variable volatile substances) and electrophilia (use of electric current during sexual activity)--both also intended to enhance the sexual stimulation. These forms of sexual practice are less prevalent than asphyxiophilia.

    Alcohol withdrawal is a common clinical condition that has a variety of complications and morbidities. The manifestations can range from mild agitation to withdrawal seizures and delirium tremens. The treatments for alcohol withdrawal include benzodiazepines, anticonvulsants, beta-blockers and antihypertensives. Although benzodiazepines are presently a first-line therapy, there is controversy regarding the efficacies of these medications compared with others. Treatment protocols often involve one of two contrasting approaches: symptom-triggered versus fixed-schedule dosing of benzodiazepines. We describe these protocols in our review and examine the data supporting symptom-triggered dosing as the preferred method for most patients in withdrawal.The Clinical Institute Withdrawal Assessment for Alcohol scoring system for alcohol withdrawal streamlines care, optimizes patient management, and is the best scale available for withdrawal assessment. Quality improvement implications for inpatient management of alcohol withdrawal include increasing training for signs of withdrawal and symptom recognition, adding new hospital protocols to employee curricula, and ensuring manageable patient-to-physician and patient-to-nurse ratios.

  19. [The concept of loss of chance: A major evolution in the definition of damage or how to prevent litigation for loss of chance?].

    Science.gov (United States)

    Nguyen, T-D

    2016-07-01

    The concept of medical error in responsibility litigation was based until the past last years on a necessary direct and definite causal link between fault and injury. In France, since the 1960s and increasingly during the last decade, the idea of loss of chance arose, considered as a new and genuine prejudice (practically, a fixable damage); it became the subject of several legal precedents from the Cour de cassation and the Conseil d'État. Thus, plaintiffs may currently demand a compensation for a loss of chance even though a doubt exists on the causal link between the fault and the observed damage. The most frequent litigation circumstances implying a loss of chance are lack of information, lack or delay in diagnosis, delay in action, and default in medical assessment. Based on practical cases, the author presents the most propitious situations where litigation for loss of chance may occur and discusses possible preventive measures.

    1985-01-01

    Some reports in the literature suggest a correlation between acceptance of traditional Latin American family values and alcoholism in Hispanic males. To examine the effects of traditional values on alcoholism, the authors surveyed 151 lower-class Puerto Rican alcoholics (126 males and 25 females), using a scale to measure Hispanic-American family values. The scores of these patients were compared with those of 116 lower-class Puerto Rican nonalcoholics (45 males and 71 females). A path model was constructed with alcoholism as the dependent variable, the Traditional Scale scores as an intervening variable, and demographic variables which may also influence alcoholism (such as sex, age, years of residence in the United States, education, and English ability) as independent variables. Overall, the findings show that traditionalism is a significant predictor of alcoholism, both directly and as an intervening variable in the relation between sex and alcoholism, and education and alcoholism. However, sex and years of residence in the United States were both stronger direct predictors of alcoholism than was traditionalism. These results support the hypothesis that the manifestations of alcoholism in lower-class Puerto Ricans are influenced by cultural attitudes.

    Full Text Available Abstract Alcoholism is a chronic remitting and relapsing condition; its aetiology and pathophysiology remains largely obscure despite recent advances. This review summarises the current knowledge about the causation (biological or psychological of alcohol addiction. This involves heredity, candidate genes, alcohol metabolism regulation and the influence of alcohol in the pathophysiology of the different neurotransmitter systems. Alcohol addiction is a multifactorial phenomenon where personality structure, individual state of mind and social influences are in constant interaction with brain neurobiology and pathophysiology. This disorder influences different sexes in different ways and causes major problems, especially in developed societies.

  8. Second-chance signal transduction explains cooperative flagellar switching.

    Directory of Open Access Journals (Sweden)

    Henry G Zot

    Full Text Available The reversal of flagellar motion (switching results from the interaction between a switch complex of the flagellar rotor and a torque-generating stationary unit, or stator (motor unit. To explain the steeply cooperative ligand-induced switching, present models propose allosteric interactions between subunits of the rotor, but do not address the possibility of a reaction that stimulates a bidirectional motor unit to reverse direction of torque. During flagellar motion, the binding of a ligand-bound switch complex at the dwell site could excite a motor unit. The probability that another switch complex of the rotor, moving according to steady-state rotation, will reach the same dwell site before that motor unit returns to ground state will be determined by the independent decay rate of the excited-state motor unit. Here, we derive an analytical expression for the energy coupling between a switch complex and a motor unit of the stator complex of a flagellum, and demonstrate that this model accounts for the cooperative switching response without the need for allosteric interactions. The analytical result can be reproduced by simulation when (1 the motion of the rotor delivers a subsequent ligand-bound switch to the excited motor unit, thereby providing the excited motor unit with a second chance to remain excited, and (2 the outputs from multiple independent motor units are constrained to a single all-or-none event. In this proposed model, a motor unit and switch complex represent the components of a mathematically defined signal transduction mechanism in which energy coupling is driven by steady-state and is regulated by stochastic ligand binding. Mathematical derivation of the model shows the analytical function to be a general form of the Hill equation (Hill AV (1910 The possible effects of the aggregation of the molecules of haemoglobin on its dissociation curves.

    College students in the U.S. continue to drink in hazardous ways and experience a range of alcohol-related consequences. Personalized feedback interventions (PFIs), which often include normative components comparing personal drinking to that of similar peers, have been effective in reducing alcohol outcomes among college students. Though normative perceptions of the quantity and frequency of alcohol use have been examined in many studies, norms for alcohol-related consequences have received less attention. The current study examined self-other discrepancies (SODs) for alcohol-related consequences among college students. Participants overestimated how often alcohol-related consequences are experienced by other same-sex students on campus and rated consequences as more acceptable for others to experience than themselves. No differences in SODs were found between those who did and did not report alcohol use. Future studies should examine the efficacy of PFIs that incorporate normative feedback on alcohol-related consequences.

    It has been proposed that concomitant substances of abuse may have additive or synergistic properties such that alcoholics using other substances of abuse concurrently may have a harder time giving up alcohol than alcoholics abusing only alcohol. The present study surveyed 291 alcoholics in an alcohol treatment program and 86 social drinker controls matched on age, education, SES and gender. Alcohol consumption, smoking, coffee intake, other substances of abuse. Beck depression and Spielberger Anxiety (State) were measured. Alcoholics drank significantly more alcohol than did social drinkers per day (350.19 cc versus 28.08 cc, p less than 0.001), consumed more caffeine/day (486.3 mg versus 339.9 mg, p less than 0.002), smoked more cigarettes/day (27.8 versus 12.8, p less than 0.001), were more depressed (16.8 versus 4.4 (Beck), p less than 0.0001), had lower internal locus of control scores (37.6 versus 39.7, p less than 0.005), had higher scores on control by chance (22.7 versus 20.2, p less than 0.03) and were significantly more anxious (52.5 versus 33.9 on Spielberger's State Inventory p less than 0.0001). Some patients used stimulants, tranquilizers, depressants, narcotics or toluene. Only 3/258 abused alcohol without using other drugs. Results support earlier studies showing strong associations between alcohol and smoking and between alcohol and caffeine consumption. The alcoholic abusing only alcohol is very rare. Treatment programs need to pay attention to concomitant drugs of abuse.

  19. Dependent-Chance Programming Models for Capital Budgeting in Fuzzy Environments

    2008-01-01

    Capital budgeting is concerned with maximizing the total net profit subject to budget constraints by selecting an appropriate combination of projects. This paper presents chance maximizing models for capital budgeting with fuzzy input data and multiple conflicting objectives. When the decision maker sets a prospec-tive profit level and wants to maximize the chances of the total profit achieving the prospective profit level, a fuzzy dependent-chance programming model, a fuzzy multi-objective dependent-chance programming model, and a fuzzy goal dependent-chance programming model are used to formulate the fuzzy capital budgeting problem. A fuzzy simulation based genetic algorithm is used to solve these models. Numerical examples are provided to illustrate the effectiveness of the simulation-based genetic algorithm and the po-tential applications of these models.

  20. Motivation to change drinking behavior: the differences between alcohol users from an outpatient gastroenterology clinic and a specialist alcohol treatment service

    Neliana Buzi Figlie

    Full Text Available CONTEXT AND OBJECTIVE: For some patients who have developed significant alcohol-related physical disease, total abstinence from alcohol may offer the best chance of survival. The aim of this study was to investigate motivation for treatment in two groups of alcohol users: outpatients from the gastroenterology clinic and outpatients from the specialist alcohol treatment service. DESIGN AND SETTING: Cross-sectional study, at a federally funded public teaching hospital. METHODS: The sample studied was 151 outpatients from the gastroenterology clinic and 175 from the specialist alcohol treatment service. The interview was conducted in the outpatient clinics at the first appointment, and consisted of demographic questions and scales for measuring quality of life, alcohol dependence, pattern of alcohol, motivation for treatment and consequences of alcohol consumption. RESULTS: The results suggested that outpatients from the gastroenterology clinic were less dependent on alcohol, had suffered fewer consequences from alcohol and had fewer emotional and mental health problems than did the outpatients from the alcohol treatment service. In relation to their stages of change, the gastroenterology outpatients presented high precontemplation scores at the beginning of treatment while outpatients of alcohol treatment service showed higher scores in contemplation, action and maintenance. CONCLUSION: The medical treatment may be a reason for the temporary alcohol abstinence behavior among the gastroenterology outpatients.

  1. Oral sex and oral health: An enigma in itself

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Oral sex is commonly practiced by sexually active couples of various age groups, including male-female and same-gender adolescents. The various type of oral sex practices are fellatio, cunnilingus, and analingus. Oral sex can transmit oral, respiratory, and genital infections from one site in body to the other. Oral health has a direct correlation on the transmission of infection; a cut in the mouth, bleeding gums, lip sores or broken skin increases chances of life-threatening infections. Although oral sex is considered a low risk activity, it is important to use protection such as physical barriers, health and medical issues, ethical issues, and oral hygiene and dental issues. The ulcerations or unhealthy periodontium in mouth accelerates the phenomenon of transmission of infections into the circulation. Thus, consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

    Sex determination is a major switch in the evolutionary history of angiosperm, resulting 11% monoecious and dioecious species. The genomic sequences of papaya sex chromosomes unveiled the molecular basis of recombination suppression in the sex determination region, and candidate genes for sex determination. Identification and analyses of sex determination genes in cucurbits and maize demonstrated conservation of sex determination mechanism in one lineage and divergence between the two systems. Epigenetic control and hormonal influence of sex determination were elucidated in both plants and animals. Intensive investigation of potential sex determination genes in model species will improve our understanding of sex determination gene network. Such network will in turn accelerate the identification of sex determination genes in dioecious species with sex chromosomes, which are burdensome due to no recombination in sex determining regions. The sex determination genes in dioecious species are crucial for understanding the origin of dioecy and sex chromosomes, particularly in their early stage of evolution.

    Full Text Available Sex, though not everything in life, is a profoundly important aspect of human existence. It has evolved to serve more than reproductive functions; relational and recreational functions having taken precedence over procrea­tional. Sex has come to play a much wider socio-psychological function.Human sexuality is complex and multidimensional. It is subject to influence by multitude of factors often grouped as biological (e.g. genes, hormones, psychological (e.g. fear, anxiety, mood and socio-cultural (e.g. sex roles, values- religious/moral/ethical, customs. It is the interaction and interrelationship of these factors from the time of conception, through intrauterine life, infancy, childhood and adolescence, till adulthood (even later in life that determine the sexual development expressed as sexual attitudes and behaviour of the people. Learning, both social and cognitive, plays a significantly important role in such development.Sexual dysfunctions in men and women, result from factors often categorised as physical or organic and psychological; more often a combination may be involved. Experience has shown that in majority of men and women in India having sexual problems, ignorance misconceptions and prevailing myths are invariably responsible in the causation of Ihese problems. Sexual problems in individual man (e.g. erectile failure and woman (e.g. vaginismus cause anxiety, feelings of frustration, lowered self esteem and symptoms of depression. The condition may also affect the spouse; he/she, as a reaction to the problem in the partner, may develop sexual and psychosocial problems including distressed marital relationship. This may also have influence on general couple relationship, effecting adversely the quality of family life.Modern therapeutic endevours have made it possible now to offer effective therapy to most people who seek help for their sexual problems, thus preventing the consequences on couple relationship.

    Alcohol's adverse public health impact includes disease, injury, violence, disability, social problems, psychiatric illness, drunk driving, drug use, unsafe sex, and premature death. Furthermore, alcohol is a confirmed human carcinogen. The International Agency for Research on Cancer concluded that alcohol causes cancer of the oral cavity, pharynx, larynx, esophagus, liver, colon-rectum, and breast. World Cancer Research Fund/American Institute for Cancer Research concluded that the evidence justifies recommending avoidance of consuming any alcohol, even in small quantities. Despite being responsible for 3.8% of global deaths (2,255,000 deaths) and 4.6% of global disability-adjusted life years in 2004, alcohol consumption is increasing rapidly in China and Asia. Contrary to the World Health Assembly's call for global control action, Hong Kong has reduced wine and beer taxes to zero since 2008. An International Framework Convention on Alcohol Control is urgently needed. Increasing alcohol taxation and banning alcohol advertisement and promotion are among the most effective policies.

    The onset and development of preschoolers' awareness of sex role stereotypes, gender labeling, gender identity, and sex-typed toy preference were explored in 26-, 31-, and 36-month-old children. Gender labeling, gender identity, sex-typed toy preferences, and awareness of adult sex role differences were observed in significantly more 26-month-old children than would have been expected by chance. Verbal gender labeling was observed in a majority of 26-month-olds, while verbal and nonverbal gender identity were observed in a majority of 31-month-olds. Nonverbal gender labeling and awareness of adult sex role differences were observed in a majority of children by 36 months. No evidence of awareness of sex differences in children's toys was found in the majority of children at any age. Awareness of sex role differences in children's toys was not related to awareness of adult sex role differences. Brighter children were more aware of adult sex role differences. Sex-typed toy preference was not related to awareness of sex role differences but was related to gender identity. Predictors of sex role development included the mothers' employment, and the father's personality traits, attitudes toward women, and sex-typed activities in the home. Implications for theories of early sex role development are discussed.

    This study investigated the influence of alcohol checks and social norm on self-reported driving under the influence of alcohol above the legal limit (DUI). The analysis was based on the responses of 12,507 car drivers from 19 European countries to the SARTRE-4 survey (2010). The data were analysed by means of a multiple logistic regression-model on two levels: (1) individual and (2) national level. On the individual level the results revealed that driving under the influence (DUI) was positively associated with male gender, young age (17-34), personal experience with alcohol checks, the perceived likelihood of being checked for alcohol, perceived drunk driving behaviour of friends (social norm) and was negatively associated with higher age (55+). On a national level, the results showed a negative association with a lower legal alcohol limit (BAC 0.2g/l compared with BAC 0.5g/l) and the percentage of drivers checked for alcohol. DUI was positively associated with the percentage of respondents in the country that reported that their friends drink and drive (social norm). The comparison of the results obtained on national and individual levels shows a paradoxical effect of alcohol checks: Countries with more alcohol checks show lower DUI (negative association) but respondents who have been personally checked for alcohol show a higher chance of DUI (positive association). Possible explanations of this paradox are discussed. The effects of the social norm variable (perceived drunk driving behaviour of friends) are positively associated with DUI on both levels.

    2010-07-01

    We examined the within-person relationships between daily work stressors and alcohol consumption over 14 consecutive days in a sample of 106 employed college students. Using a tension reduction theoretical framework, we predicted that exposure to work stressors would increase alcohol consumption by employed college students, particularly for men and those with stronger daily expectancies about the tension reducing properties of alcohol. After controlling for day of the week, we found that hours worked were positively related to number of drinks consumed. Workload was unrelated to alcohol consumption, and work-school conflict was negatively related to consumption, particularly when students expressed strong beliefs in the tension reducing properties of alcohol. There was no evidence that the effects of work stressors were moderated by sex. The results illustrate that employment during the academic year plays a significant role in college student drinking and suggest that the employment context may be an appropriate intervention site to address the problem of student drinking.

    OBJECTIVES: to analyze the effect of self-esteem, assertiveness, self-efficacy and resiliency on alcohol and tobacco consumption in adolescents. METHOD: a descriptive and correlational study was undertaken with 575 adolescents in 2010. The Self-Esteem Scale, the Situational Confidence Scale, the Assertiveness Questionnaire and the Resiliency Scale were used. RESULTS: the adjustment of the logistic regression model, considering age, sex, self-esteem, assertiveness, self-efficacy and resiliency, demonstrates significance in the consumption of alcohol and tobacco. Age, resiliency and assertiveness predict alcohol consumption in the lifetime and assertiveness predicts alcohol consumption in the last year. Similarly, age and sex predict tobacco consumption in the lifetime and age in the last year. CONCLUSION: this study can offer important information to plan nursing interventions involving adolescent alcohol and tobacco users. PMID:25591103

    The aim of this study was to calculate the number and costs of hospital bed-days due to alcohol use in Ireland over the five year period 2000 to 2004. Age and sex specific Irish alcohol-attributable-fractions (AAFs) were developed by combining international risk estimates with Irish consumption data where available; where not available international AAFs were used. These were applied to national datasets to count the number and costs of bed-days wholly caused and prevented by alcohol and that proportion of bed-days that were partially caused and prevented by alcohol. Between 2000 and 2004, alcohol was estimated to have caused 3,428,973 (10.3%) and prevented 529,239 (1.6%) of hospital bed-days, giving a net number of bed-days due to alcohol of 2,899,734 (8.7%). Over this period the hospital inpatient costs attributed to the negative effects of alcohol were 953,126,381 euros, the costs attributed to hospitalisations prevented were 147,968,164 euros; giving net costs of alcohol-attributed bed-days of 805,158,217 euros. Chronic conditions accounted for 3,262,408 (95%) hospital bed-days due to the harmful effects of alcohol. Conditions not wholly due to alcohol accounted for 2,297,412 (67%) hospital bed-days due to the harmful effects of alcohol. The negative impacts of alcohol were greater than previously thought and spread across the whole population.

    A retrospective study was conducted in order to determine the prevalence and concentration of alcohol in post-mortem blood samples sent for toxicological analysis in Cork City and County in 2003 and 2004. Post mortem reports of these deaths were reviewed for the presence or absence of alcohol at the time of autopsy, blood alcohol concentration (BAC) at time of death, age and sex of the decedents. Of samples sent for blood alcohol analysis (BAA), 38.4% were positive for alcohol. Significant differences were found between the proportions of alcohol positive cases by cause of death. Alcohol positive cases were significantly younger (44.3 +\\/- 17.8 years) than alcohol negative cases (51.9 +\\/- 19.4 years) and fifty two percent of drivers were positive for alcohol at the time of death. Awareness of the harmful and potentially fatal effects of alcohol should continue to be raised within the community, so as to prevent future fatalities.

  16. Chance between holism and reductionism: tensions in the conceptualisation of Life.

    Wolfe, Charles T

    2012-09-01

    In debates between holism and reductionism in biology, from the early twentieth century to more recent re-enactments involving genetic reductionism, developmental systems theory or systems biology, the role of chance - the presence of theories invoking chance as a strong explanatory principle - is hardly ever acknowledged. Conversely, Darwinian models of chance and selection (Dennett, 1995; Kupiec, 1996, 2009) sit awkwardly with reductionist and holistic concepts, which they alternately challenge or approve of. I suggest that the juxtaposition of chance and the holism-reductionism pair (at multiple levels, ontological and methodological, pertaining to the vision of scientific practice as well as to the foundations of a vision of Nature, implicit or explicit) allows the theorist to shed some new light on these perennial tensions in the conceptualisation of Life.

    The discovery of radioactivity by Henri Becquerel is frequently called serendipitous, because on March 1, 1896, he developed ``unexposed'' photographic plates, which he had kept near a uranium salt, and found dark images on them. I show that Becquerel's discovery was a process in which, even in its early stage in 1896, chance entered in a number of episodes, and that his discovery resulted from a complex interaction of logic and chance.

    The purpose of this study was to understand the diet, drinking, and smoking behaviors of university students and to analyze the health behaviors that could be a risk factor for non-communicable diseases (NCDs) in order to contribute to the promotion of NCD prevention in youth. The survey was carried out using a questionnaire with closed questions including items about health behaviors. The subjects surveyed were students of 10 universities on the main island of Japan (1,196 valid responders). The score for the nutritional balance was significantly low in the group living alone for both students in their teens and 20s. For the frequency of not eating breakfast, results suggest that living alone and increase in age are related to the lack of breakfast for both males and females. Teenage males living alone tended to lack in consideration for the intake of animal fat than those not living alone. The females showed a higher tendency to eat sweets and snacks during the day than the males. For the males who living alone, results suggest that they tended to have a higher or equal alcohol intake to females in their 20s and males in their 20s not living alone even when they are underage. Males in their 20s tended to have a higher amount and frequency of smoking than other groups regardless of their living arrangement. Accumulation of health behavior that could be a risk for NCDs was found in some of the groups, such as males living alone.

    Full Text Available Context Pancreatitis is a major public health problem with high associated economic costs. The incidence of pancreatitis has increased in many European countries in recent decade. Accumulated research and empirical evidence suggests that excessive alcohol consumption is a major risk factor for both acute and chronic pancreatitis. Objective The aim of this study was to examine the aggregate-level relation between the alcohol consumption and pancreatitis mortality rates in Russia. Method Age-standardized sex-specific male and female pancreatitis mortality data for the period 1970-2005 and data on overall alcohol consumption were analyzed by means ARIMA (autoregressive integrated moving average time series analysis. Alcohol consumption was significantly associated with both male and female pancreatitis mortality rates: a 1 liter increase in overall alcohol consumption would result in a 7.0% increase in the male pancreatitis mortality rate and in 2.3% increase in the female mortality rate. The results of the analysis suggest that 63.1% of all male pancreatitis deaths and 26.8% female deaths in Russia could be attributed to alcohol. Conclusions The outcomes of this study provide indirect support for the hypothesisthat unfavorable mixture of higher overall level of alcohol consumption and binge drinking pattern is an important contributor to the pancreatitis mortality rate in Russian Federation.

    It has become popular for men who have sex with men (MSM) to use mobile-phone geosocial networking applications (mobile apps) to find sex partners. A cross-sectional online survey was conducted in Taiwan to compare the sexual and substance-use behaviors of MSM seeking sex partners through the internet and mobile apps. Of the 1060 participants, 65.8% used the internet via computer and 37.7% used a mobile app to find sexual partners, while 30.3% used recreational drugs or alcohol in the previous 6 months. MSM who exclusively used mobile apps to seek sex partners were significantly more likely than MSM seeking sex via computer to be older, to have used recreational drugs or alcohol, and to have sex with HIV-positive partners. Additionally, using mobile apps to seek sex partners was significantly associated with having sex with online partners through either mobile apps or computer-based internet use (adjusted odds ratio (AOR), 7.12 [3.87-13.11]), self-reporting as HIV-positive (AOR, 2.24 [1.12-4.12]), using recreational drugs (AOR, 1.67 [1.21-2.32]), having disclosed HIV status to sexual partners (AOR, 1.44 [1.03-2.02]), and having sex with HIV-positive partners (AOR, 1.81 [1.06-3.10]). In conclusion, the mobile apps may serve as a feasible platform for HIV-positive MSM to find other HIV-positive partners.

  11. Alcoholism and alcohol drinking habits predicted from alcohol dehydrogenase genes

    Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white...... men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence......, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking.

  12. Trade law and alcohol regulation: what role for a global Alcohol Marketing Code?

    Science.gov (United States)

    Mitchell, Andrew D; Casben, Jessica

    2017-01-01

    Following calls for restrictions and bans on alcohol advertising, and in light of the tobacco industry's challenge to Australia's tobacco plain packaging measure, a tobacco control measure finding support in the World Health Organization (WHO) Framework Convention on Tobacco Control, this paper considers what role, if any, an international alcohol marketing code might have in preventing or reducing the risk of challenges to domestic alcohol marketing restrictions under trade rules. Narrative review of international trade and health instruments and international trade court judgements regarding alcohol products and marketing restrictions. The experience of European trade courts in the litigation of similar measures suggests that World Trade Organization rules have sufficient flexibility to support the implementation of alcohol marketing restrictions. However, the experience also highlights the possibility that public health measures have disproportionate and unjustifiable trade effects and that the ability of a public health measure to withstand a challenge under trade rules will turn on its particular design and implementation. Measures implemented pursuant to international public health instruments are not immune to trade law challenges. Close collaboration between health policymakers, trade officials and lawyers, from as early as the research stage in the development of a measure to ensure a robust evidence base, will ensure the best chance of regulatory survival for an international marketing code. © 2016 Society for the Study of Addiction.

  13. Do women develop alcoholic brain damage more readily than men?

    Science.gov (United States)

    Mann, K; Batra, A; Günthner, A; Schroth, G

    1992-12-01

    Chronic alcoholism is related to brain damage (i.e., volume changes) in both men and women. There is an open question whether the brains of women are more vulnerable than those of men to alcohol toxicity. The present follow-up study focuses on a direct comparison of sex-related differences in alcoholic brain shrinkage and its reversibility. In a prospective design, a random sample of 65 alcoholics of both sexes (51 males and 14 females) was studied. Computerized tomography brain scans before and after a 6-week inpatient treatment program with controlled abstinence revealed a significant re-expansion of the brain as assessed by linear measurements. By controlling for moderating variables such as age, mean daily alcohol consumption, liver dysfunction, etc. the degree of brain shrinkage was found to be similar in men and women despite significantly shorter ethanol expositions in the women. These findings corroborate the hypotheses of other investigators about basic biological differences between the two sexes as to the effects of alcohol. The hypothesis of an enhanced vulnerability of women to acute and chronic complications of alcoholism is supported.

  15. Vulnerability to alcohol-related problems: a policy brief with implications for the regulation of alcohol marketing.

    2017-01-01

    The concern that alcohol advertising can have detrimental effects on vulnerable viewers has prompted the development of codes of responsible advertising practices. This paper evaluates critically the concept of vulnerability as it applies to (1) susceptibility to alcohol-related harm and (2) susceptibility to the effects of marketing, and describes its implications for the regulation of alcohol marketing. We describe the findings of key published studies, review papers and expert reports to determine whether these two types of vulnerability apply to population groups defined by (1) age and developmental history; (2) personality characteristics; (3) family history of alcoholism; (4) female sex and pregnancy risk; and (5) history of alcohol dependence and recovery status. Developmental theory and research suggest that groups defined by younger age, incomplete neurocognitive development and a history of alcohol dependence may be particularly vulnerable because of the disproportionate harm they experience from alcohol and their increased susceptibility to alcohol marketing. Children may be more susceptible to media imagery because they do not have the ability to compensate for biases in advertising portrayals and glamorized media imagery. Young people and people with a history of alcohol dependence appear to be especially vulnerable to alcohol marketing, warranting the development of new content and exposure guidelines focused on protecting those groups to improve current self-regulation codes promoted by the alcohol industry. If adequate protections cannot be implemented through this mechanism, statutory regulations should be considered. © 2016 Society for the Study of Addiction.

    2004-01-01

    This article is designed to review the representations of alcoholism provided by members of an association of former alcoholics, namely Alcoholics Anonymous (AA), based on partial results from a qualitative survey conducted in the Sapopemba group of AA in a neighborhood on the outskirts of the city of Sao Paulo, Brazil. The article thus analyzes alcoholism from an emic perspective, i.e., how it is conceived and managed by those who acknowledge themselves as being "sick as alcoholics", how they explain the sickness, how they experience it, and how they endeavor to overcome it. The purpose is to present AA and its treatment strategy and to highlight the link made by the association by conceiving of alcoholism as a physical, moral, and spiritual illness.

    Patrick, Megan E; Maggs, Jennifer L; Lefkowitz, Eva S

    2015-06-01

    Daily links between alcohol use and sexual behaviors were examined in a longitudinal study of college students. Hierarchical linear models predicted sexual behaviors by characteristics of persons (N=731; Level 3), semesters (N=4,345, Level 2), and days (N=56,372, Level 1). On a given day, consuming more drinks and binge drinking were associated with greater odds of kissing, touching, oral sex, and penetrative sex. Consistent with alcohol myopia and expectancy theories, associations between binge drinking and sexual behaviors were stronger for students not in romantic relationships, for students with stronger alcohol-sex expectancies, and for oral and penetrative sex. Findings suggest that within-day links between alcohol use and sexual behaviors are evident across college, with variations based on individual and relationship factors.

    2007-12-01

    Either diabetes or alcohol abuse can impair cognitive function, especially at older ages. Whether a history of alcohol abuse increases the risk for cognitive impairment in diabetic patients has not been examined. Cognitive function of type 2 diabetic subjects with a history of alcohol abuse was expected to be more impaired than that of subjects with either diabetes or alcohol abuse alone. Men, 55 years of age, were categorized as 15 alcoholic-diabetic; 15 alcoholic-nondiabetic; 15 nonalcoholic-diabetic; 15 nonalcoholic-nondiabetic, and matched on age, sex, and education. Participants' verbal memory, visuospatial memory, and executive functions were assessed using a neurocognitive test battery. Significant interactions of diabetes and alcoholism for Visual Delayed Recall, Story Immediate Recall, and Story Delayed Recall implied that diabetes and alcohol abuse enhanced each other's effect in lowering cognitive test scores. Alcohol abuse history in older diabetic subjects presents an increased risk for cognitive impairment.

    While the harmful effects of alcohol during pregnancy are well-established, the consequences of alcohol intake during lactation have been far less examined. We reviewed available data on the prevalence of alcohol intake during lactation, the influence of alcohol on breastfeeding......, the pharmacokinetics of alcohol in lactating women and nursing infants and the effects of alcohol intake on nursing infants. A systematic search was performed in PubMed from origin to May 2013, and 41 publications were included in the review. Approximately half of all lactating women in Western countries consume...... alcohol while breastfeeding. Alcohol intake inhibits the milk ejection reflex, causing a temporary decrease in milk yield. The alcohol concentrations in breast milk closely resemble those in maternal blood. The amount of alcohol presented to nursing infants through breast milk is approximately 5...

  2. Chance, choice, and consciousness the role of mind in the quantum brain

    CERN Document Server

    Stapp, Henry P

    1995-01-01

    Contemporary quantum mechanical description of nature involves two processes. The first is a dynamical process governed by the equations of local quantum field theory. This process is local and deterministic but it generates a structure that is not compatible with observed reality. A second process is therefore invoked. This second process somehow analyzes the structure generated by the first process into a collection of possible observable realities, and selects one of these as the actually appearing reality. This selection process is not well understood. It is necessarily nonlocal and, according to orthodox thinking, is governed by an irreducible element of chance. The occurrence of this irreducible element of chance means that the theory is not naturalistic: the dynamics is controlled in part by something that is not part of the physical universe. The present work describes a quantum mechanical model of brain dynamics in which the quantum selection process is a causal process governed not by pure chance bu...

    2005-01-01

    In Chance, celebrated mathematician Amir D. Aczel turns his sights on probability theory—the branch of mathematics that measures the likelihood of a random event. He explains probability in clear, layman's terms, and shows its practical applications. What is commonly called luck has mathematical roots and in Chance, you'll learn to increase your odds of success in everything from true love to the stock market. For thousands of years, the twin forces of chance and mischance have beguiled humanity like none other. Why does fortune smile on some people, and smirk on others? What is luck, and why does it so often visit the undeserving? How can we predict the random events happening around us? Even better, how can we manipulate them? In this delightful and lucid voyage through the realm of the random, Dr. Aczel once again makes higher mathematics intelligible to us.

    Voss, L; Cole, P A; D'Amato, C

    1996-01-01

    In 1948, G. Q. Chance described a traumatic spinal injury as a "horizontal splitting of the spine," which has since come to be known as the Chance fracture. In 1965, the first such fracture was described by Howland et al. in a passenger as a result of a lap seatbelt during a motor vehicle accident. Until 1980, there were 36 such injuries reported, but the number of reports has since risen with the advent of mandatory seatbelt laws. We report three cases occurring in a single accident when a popular 4-wheel drive vehicle moving at only approximately 25 mph struck a tree, causing flexion-distraction fractures in all three children wearing lapbelts while seated in the rear seat. All three had a different Chance fracture variant and associated intraabdominal injuries. One child was rendered paraplegic. The purpose of this report is to promote awareness of the associated injuries, and to encourage appropriate use and development of passenger restraints for children.

  5. Chance-Constrained AC Optimal Power Flow for Distribution Systems With Renewables

    Energy Technology Data Exchange (ETDEWEB)

    DallAnese, Emiliano; Baker, Kyri; Summers, Tyler

    2017-09-01

    This paper focuses on distribution systems featuring renewable energy sources (RESs) and energy storage systems, and presents an AC optimal power flow (OPF) approach to optimize system-level performance objectives while coping with uncertainty in both RES generation and loads. The proposed method hinges on a chance-constrained AC OPF formulation where probabilistic constraints are utilized to enforce voltage regulation with prescribed probability. A computationally more affordable convex reformulation is developed by resorting to suitable linear approximations of the AC power-flow equations as well as convex approximations of the chance constraints. The approximate chance constraints provide conservative bounds that hold for arbitrary distributions of the forecasting errors. An adaptive strategy is then obtained by embedding the proposed AC OPF task into a model predictive control framework. Finally, a distributed solver is developed to strategically distribute the solution of the optimization problems across utility and customers.

    A short CV of Britton Chance, an outstanding American biophysicist and biochemists, who has passed away in November 2010, is presented. Chance invented and applied in biochemical research fast recording of difference spectra during chemical reactions. Due to this technique he discovered and studied formation of enzyme-substrate complexes as exemplified by the peroxidase reaction. He also described spectral changes of electron carriers of mitochondrial respiratory chain that accompany transition from the resting to the active (phosphorylating) states. Applying vibrating platinum electrode, he recorded changes in the rate of oxygen uptake by isolated mitochondria in resting and phosphorylating states and defined the so-called respiratory states, called after his name. He was the first to describe formation of reactive oxygen species by mitochondria. Britton Chance was a devoted yachtsman and won a gold medal for the United States in sailing at the 1952 Olympic Games in Helsinki.

    Alcohol drinking habits and alcoholism are partly genetically determined. Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence interval (CI): 9.1-11) among men with the ADH1B.1/1 genotype compared to 7.5 drinks (95% CI: 6.4-8.7) among men with the ADH1B.1/2 genotype, and the odds ratio (OR) for heavy drinking was 3.1 (95% CI: 1.7-5.7) among men with the ADH1B.1/1 genotype compared to men with the ADH1B.1/2 genotype. Furthermore, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking. For example, the OR for heavy drinking was 1.4 (95% CI: 1.1-1.8) among men with the ADH1C.1/2 genotype and 1.4 (95% CI: 1.0-1.9) among men with the ADH1B.2/2 genotype, compared with men with the ADH1C.1/1 genotype. Results for ADH1B and ADH1C genotypes among men and women were similar. Finally, because slow ADH1B alcohol degradation is found in more than 90% of the white population compared to less than 10% of East Asians, the population attributable risk of heavy drinking and alcoholism by ADH1B.1/1 genotype was 67 and 62% among the white population compared with 9 and 24% among the East Asian population.

  10. Alcohol Dependence and Alcoholic Liver Disease

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Alcohol dependence is a disabling condition that has a high prevalence, but in Europe only a small fraction of the people diagnosed with alcohol abuse and dependence are treated, representing the widest treatment gap, as compared with other mental disorders. Early diagnosis and monitoring of alcoholic liver disease (ALD is still insufficiently solved. Although ALD is the most common cause for liver disease in the Western world, it largely remains underestimated and underdiagnosed for many reasons. The recent introduction of non-invasive elastographic techniques such as transient elastography (TE has significantly improved the early diagnosis of alcoholic liver cirrhosis (ALC. As demonstrated in the literature, inflammation-associated liver stiffness (LS rapidly decreases during alcohol detoxification, and is also directly correlated to change in LS in both abstinent and relapsing patients. Newly published data show that LS could be used to monitor and validate hepatoprotective effects during nalmefene usage. Nalmefene is an opioid system modulator that diminishes the reinforcing effects of alcohol, helping the patient to reduce drinking. Three randomised, multicentre, double-blind, placebo-controlled, parallelgroup Phase III studies were designed to assess the efficacy and safety of nalmefene in reducing alcohol consumption. Patients with a high or very high drinking risk level (DRL at baseline and randomisation show a clinically significant effect from nalmefene treatment, which is generally well tolerated. Moreover, reduced alcohol consumption supported by nalmefene in combination with psychosocial support may indeed help to reduce the alcohol-related burden and the large treatment gap.

    Full Text Available Abstract Background This study examined cross-sectional data collected from substance-using female sex workers (FSW and non-sex workers (non-SW in Pretoria, South Africa, who entered a randomized controlled trial. Methods Women who reported alcohol use and recently engaging in sex work or unprotected sex were recruited for a randomized study. The study sample (N = 506 comprised 335 FSW and 171 female non-SW from Pretoria and surrounding areas. Self-reported data about alcohol and other drug use as well as treatment needs and access were collected from participants before they entered a brief intervention. Results As compared with female non-SW, FSW were found to have a greater likelihood of having a past year diagnosis of alcohol or other drug abuse or dependence, having a family member with a history of alcohol or other drug abuse, having been physically abused, having used alcohol before age 18, and having a history of marijuana use. In addition, the FSW were more likely to perceive that they had alcohol or other drug problems, and that they had a need for treatment and a desire to go for treatment. Less than 20% of participants in either group had any awareness of alcohol and drug treatment programs, with only 3% of the FSW and 2% of the non-SW reporting that they tried but were unable to enter treatment in the past year. Conclusion FSW need and want substance abuse treatment services but they often have difficulty accessing services. The study findings suggest that barriers within the South African treatment system need to be addressed to facilitate access for substance-using FSW. Ongoing research is needed to inform policy change that fosters widespread educational efforts and sustainable, accessible, woman-sensitive services to ultimately break the cycle for current and future generations of at-risk South African women.

  12. Decrease of old age population mortality in Yugoslavia: Chance to increase anticipated life expectancy

    Full Text Available This study analyzes the level and structure of old age population mortality in Yugoslavia with an aim to determine the intensity of realized changes and to provide an answer to how much they are significant and to approach the positive trends noted in developed countries in the latest period. Although it was insufficiently represented in the demographic analysis, the analysis of mortality in old people is gaining importance in the world. Apart from the reasons which result from the increase in the number of old people and thus their greater participation in the total number of deceased, enviable results have been achieved in decreasing old age mortality, which are more and more in focus of interest. While earlier research reported on the dominant influence of the decrease of younger age mortality to the increase of the expectation of life at birth, recent analysis precisely confirm the importance of decreasing mortality in old people. In mortality conditions from 1997/98, an additional 13.4 years of life in average is expected for men in Yugoslavia, and 15.2 for women. During more than five decades, the anticipated life expectancy for people over the age of 65 increased for only 1.2 years for men and 1.9 years for women. Out of that, the greatest increase was realized in the period 1950/51 - 1960/61 in both sexes. A small decrease in the average life expectancy was marked with men in the period 1960/61 - 1970/71, and with women in the latest period. Otherwise, all up to the eighties, the annual rate of increase was considerably lower than the rate of increase for zero year. It was only in the period 1980/81-1990/91 that faster growth had an anticipated life expectancy for the 65 years old. However, during the nineties unfavorable changes continued with the older, especially, female population. When comparing the values of the average life expectancy for people over 65 in Yugoslavia with corresponding values in developed countries, the lagging in

    2016-06-01

    Limited research has been published regarding the association between stuttering and substance use. An earlier study provided no evidence for such an association, but the authors called for further research to be conducted using a community sample. The present study used data from a community sample to investigate whether an association between stuttering and alcohol consumption or regular smoking exists in late adolescence and adulthood. Regression analyses were carried out on data from a birth cohort study, the National Child Development Study (NCDS), whose initial cohort included 18,558 participants who have since been followed up until age 55. In the analyses, the main predictor variable was parent-reported stuttering at age 16. Parental socio-economic group, cohort member's sex and childhood behavioural problems were also included. The outcome variables related to alcohol consumption and smoking habits at ages 16, 23, 33, 41, 46, 50 and 55. No significant association was found between stuttering and alcohol consumption or stuttering and smoking at any of the ages. It was speculated that the absence of significant associations might be due to avoidance of social situations on the part of many of the participants who stutter, or adoption of alternative coping strategies. Because of the association between anxiety and substance use, individuals who stutter and are anxious might be found to drink or smoke excessively, but as a group, people who stutter are not more likely than those who do not to have high levels of consumption of alcohol or nicotine.

    Full Text Available The aim of the CHANCE project is to develop novel and affordable nutritious foods to optimize the diet and reduce the risk of diet-related diseases among groups at risk of poverty (ROP. This paper describes the methodology used in the two initial steps to accomplish the project’s objective as follows: 1. a literature review of existing data and 2. an identification of ROP groups with which to design and perform the CHANCE nutritional survey, which will supply new data that is useful for formulating the new CHANCE food. Based on the literature review, a low intake of fruit and vegetables, whole grain products, fish, energy, fiber, vitamins B1, B2, B3, B6, B12 and C, folate, calcium, magnesium, iron, potassium and zinc and a high intake of starchy foods, processed meat and sodium were apparent. However, the available data appeared fragmented because of the different methodologies used in the studies. A more global vision of the main nutritional problems that are present among low-income people in Europe is needed, and the first step to achieve this goal is the use of common criteria to define the risk of poverty. The scoring system described here represents novel criteria for defining at-risk-of-poverty groups not only in the CHANCE-participating countries but also all over Europe.

    Venue-based HIV prevention interventions, especially in sex on premise venues, can disrupt high-risk sexual networks. However, prior to intervening, it is essential to understand the person-venue dynamics that contribute to HIV risk. As such, we conducted five ethnographic observations at each of six venues where alcohol is sold and sex occurs onsite (2 each porn theaters, sex clubs, and dance clubs) frequented by gay and other men who have sex with men (G&MSM) in the Buenos Aires metropolitan area. Alcohol use, sexual behavior, and person-venue dynamics differed markedly across venue types. In dance clubs, substantial alcohol consumption often preceded visits to the darkroom for sex which, at times, included unprotected anal and vaginal intercourse. Condoms, although available, were not easily accessible. HIV prevention messaging was generally non-existent. These venues are in critical need of interventions to reduce HIV transmission risk.

    In some studies, situational factors have been shown to be stronger predictors of condomless sex than individual risk factors. Cross-sectional relationships between condomless anal sex (CAS) with HIV-serodiscordant partners and risk factors across ecological levels (individual, sexual environment) were examined using a sample (N = 60) of HIV-positive men who have sex with men (MSM) who reported multiple recent episodes of CAS. Negative binomial regressions were used to evaluate the association of contextual risk factors (e.g., substance use during sex, transactional sex, public sex, sex at a sex party) with recent condomless sex, controlling for demographics and mental health. Results demonstrated that sexual environment factors, particularly sex under the influence of drugs or alcohol (B = .019, p sex (B = .035, p sex (B = .039, p sex at a sex party was not related to CAS (p = .39). For each additional sexual environment in which men engaged, their rates of CAS increased (B = .39, p < .01). Secondary prevention interventions that are tailored to the proximal sexual environment could be maximally effective, particularly if they address substance use and other challenging sexual situations.

    Full Text Available Although alcohol intoxicated eyewitnesses are common, there are only a few studies in the area. The aim of the current study is to investigate how different doses of alcohol affect eyewitness lineup identification performance. The participants (N = 123 were randomly assigned to a 3 [Beverage: control (0.0 g/kg ethanol vs. lower (0.4 g/kg ethanol vs. higher alcohol dose (0.7 g/kg ethanol] X 2 (Lineup: target-present vs. target-absent between-subject design. Participants consumed two glasses of beverage at an even pace for 15 minutes. Five minutes after consumption the participants witnessed a film depicting a staged kidnapping. Seven days later, the participants returned to the laboratory and were asked to identify the culprit in a simultaneous lineup. The result showed that overall, the participants performed better than chance; however, their lineup performance was poor. There were no significant effects of alcohol intoxication with respect to performance, neither in target-present nor target-absent lineups. The study’s results suggest that eyewitnesses who have consumed a lower (0.4 g/kg ethanol or a higher (0.7 g/kg ethanol dose of alcohol perform at the same level as sober eyewitnesses in a lineup. The results are discussed in relation to the alcohol myopia theory and suggestions for future research are made.

    Full Text Available The author briefly interprets the research – results, referring to the phenomenon of children of alcoholics, especially the psychological and psychopathological characteristics of children of alcoholics in adolescence and young adulthood. The author presents a screening study of adolescents. The sample contains 200 high school students at age 18. The aim of the survey was to discover the relationship between alcohol consumption of parents, PTSD - related psychopathological symptoms and reported life quality of their children. The study confirmed the hypothesis about a substantial correlation between high alcohol consumption of parents, higher psychopathological symptom - expression and lower reported life quality score of their children. Higher PTSD-related symptomatology in children of alcoholics is probably resulted by home violence, which is very often present in family of alcoholics. The article also evaluated the results regarding suicide ideation of children of alcoholics, which is definitely more frequent and more intense than in their peers living in non alcohol – dependent families.

    Transgender women are disproportionately impacted by HIV. Transgender women involved in sex work may experience exacerbated violence, social exclusion, and HIV vulnerabilities, in comparison with non-sex work-involved transgender women. Scant research has investigated sex work among transgender women in the Caribbean, including Jamaica, where transgender women report pervasive violence. The study objective was to examine factors associated with sex work involvement among transgender women in Jamaica. In 2015, we implemented a cross-sectional survey using modified peer-driven recruitment with transgender women in Kingston and Ocho Rios, Jamaica, in collaboration with a local community-based AIDS service organization. We conducted multivariable logistic regression analyses to identify factors associated with paid sex and transactional sex. Exchanging oral, anal or vaginal sex for money only was categorized as paid sex. Exchanging sex for survival needs (food, accommodation, transportation), drugs or alcohol, or for money along with survival needs and/or drugs/alcohol, was categorized as transactional sex. Among 137 transgender women (mean age: 24.0 [SD: 4.5]), two-thirds reported living in the Kingston area. Overall, 25.2% reported being HIV-positive. Approximately half (n = 71; 51.82%) reported any sex work involvement, this included sex in exchange for: money (n = 64; 47.06%); survival needs (n = 27; 19.85%); and drugs/alcohol (n = 6; 4.41%). In multivariable analyses, paid sex and transactional sex were both associated with: intrapersonal (depression), interpersonal (lower social support, forced sex, childhood sexual abuse, intimate partner violence, multiple partners/polyamory), and structural (transgender stigma, unemployment) factors. Participants reporting transactional sex also reported increased odds of incarceration perceived to be due to transgender identity, forced sex, homelessness, and lower resilience, in comparison with participants reporting

    Alcohol use can lead to a cascade of problems such as increased chances of risky behavior and negative health consequences, including alcoholic liver disease and upper gastric and liver cancer. Ethanol is metabolized mainly by 2 major enzymes: alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH). Genetic variations of genes encoding the 2 enzymes are very common among East Asians but relatively rare for most other populations. Facial flushing and other physical discomforts after alcohol drinking triggered by accumulation of acetaldehyde through defective genes for ADH and ALDH have been reported. Approximately 40% of East Asians (Chinese, Japanese, and Korean) show facial flushing after drinking alcohol, known as "Asian flush," which is characterized by adverse reactions on alcohol drinking in individuals possessing the fasting metabolizing alleles for ADH, ADH1B*2, and ADH1C*1, and the null allele for ALDH and ALDH2*2. Alcoholism is determined not only by the genetic deficiency but also by behaviors that involve complex interactions between genetic and sociocultural factors. The purpose of this article was to provide nurses with the most current information about genetic and sociocultural influences on alcoholism and alcohol-related health problems specifically for East Asians and implications of this knowledge to nursing practice. The physiological phenomenon of genes and genetics in relation to alcohol metabolism in this special population is emphasized.

    Adolescents' movie sex exposure (MSE) and movie alcohol exposure (MAE) have been shown to influence later sexual behavior and drinking, respectively. No study to date, however, has tested whether these effects generalize across behaviors. This study examined the concurrent influences of early (i.e., before age 16) MSE and MAE on subsequent risky sex and alcohol use among a national sample of 1228 U.S. adolescents. Participants reported their health behaviors and movie viewing up to six times between 2003 and 2009 in telephone interviews. The Beach method was used to create a population-based estimate of each participant's MSE and MAE, which were then entered into a structural equation model (SEM) to predict lifetime risky sex and past month alcohol use at ages 18-21. For both men and women, MAE predicted alcohol use, mediated by age of initiation of heavy episodic drinking (HED) and age of sexual debut; MAE also predicted risky sex via age of sexual debut. Among men only, MSE indirectly predicted risky sex and alcohol use. Findings indicated that early exposure to risk content from movies had both specific and general effects on later risk-taking, but gender differences were evident: for men, MSE was a stronger predictor than MAE, but for women, only MAE predicted later risk behavior. These results have implications for future media research, prevention programs for adolescent sex and alcohol use, and movie ratings that can guide parents' decisions as to which movies are appropriate for their children.

    We predicted sex of 140 Snowy Owl (Bubo scandiacus) nestlings out of 34 nests at our Barrow, Alaska, study area to develop a technique for sexing these owls in the field. We primarily sexed young, flightless owls (3844 d old) by quantifying plumage markings on the remiges and tail, predicting sex, and collecting blood samples to test our field predictions using molecular sexing techniques. We categorized and quantified three different plumage markings: two types of bars (defined as markings that touch the rachis) and spots (defined as markings that do not touch the rachis). We predicted sex in the field assuming that males had more spots than bars and females more bars than spots on the remiges and rectrices. Molecular data indicated that we correctly sexed 100% of the nestlings. We modeled the data using random forests and classification trees. Both models indicated that the number and type of markings on the secondary feathers were the most important in classifying nestling sex. The statistical models verified our initial qualitative prediction that males have more spots than bars and females more bars than spots on flight feathers P6P10 for both wings and tail feathers T1 and T2. This study provides researchers with an easily replicable and highly accurate method for sexing young Snowy Owls in the field, which should aid further studies of sex-ratios and sex-related variation in behavior and growth of this circumpolar owl species. ?? 2011 The Raptor Research Foundation, Inc.

The focus will be on population, intervention and metabolic studies with respect to alcohol and plasma triglycerides. Alcohol consumption and fat ingestion are closely associated and stimulated by each other via hypothalamic signals and by an elevated cephalic response. A J-shaped relationship between alcohol intake and plasma triglycerides has been described. A normal body weight, polyphenols in red wine and specific polymorphisms of the apolipoprotein A-V and apolipoprotein C-III genes may protect against alcohol-associated hypertriglyceridemia. In contrast, obesity exaggerates alcohol-associated hypertriglyceridemia and therefore the risk of pancreatitis. High alcohol intake remains harmful since it is associated with elevated plasma triglycerides, but also with cardiovascular disease, alcoholic fatty liver disease and the development of pancreatitis. Alcohol-induced hypertriglyceridemia is due to increased very-low-density lipoprotein secretion, impaired lipolysis and increased free fatty acid fluxes from adipose tissue to the liver. However, light to moderate alcohol consumption may be associated with decreased plasma triglycerides, probably determined by the type of alcoholic beverage consumed, genetic polymorphisms and lifestyle factors. Nevertheless, patients should be advised to reduce or stop alcohol consumption in case of hypertriglyceridemia.

    The work analyzes different aspects related to alcohol consumption among homeless people and people at risk of social exclusion. The data was gathered from a representative sample of homeless people in Madrid (n = 188) and a sample of people at risk of social exclusion (n = 164) matched in sex, age, and origin (Spaniards vs. foreigners). The results showed that homeless people present a greater consumption of alcohol and have experienced more problems derived from its consumption than people at risk of social exclusion. Most of the homeless people who had alcohol-related problems had had them prior to their homelessness, and they stated they had poorer health and had experienced a greater number of homelessness episodes. Despite the relevance of problems related to alcohol among our sample, only a small percentage of the sample had participated in treatment programs for alcohol consumption.

    Full Text Available Historically, academic literature on sex work has documented the changing debates, policies, and cultural discourse surrounding the sex industry, and their impact on the rights of sex workers worldwide. As sex work scholars look to the future of sex workers’ rights, however, we are also in a critical moment of self-reflection on how sex work scholarship engages with sex worker communities, produces knowledge surrounding sex work, and represents the lived experiences of sex workers’ rights, organizing, and activism. In this short Communication, proceedings from a recent sex work research symposium entitled, Sexual Economies, Politics, and Positionality in Sex Work Research are presented. Held at the Centre for Refugee Studies at York University, this symposium is a response to the need for sex work researchers, sex workers, and sex worker-led organizations to come together and critically examine the future of research on sex work and the politics of documenting sex workers’ rights.

    Adolescents may be more sensitive to stress-induced alcohol drinking than adults, which would explain the higher prevalence of alcohol abuse and dependence in late adolescence than in adulthood. The present study analyzed the impact of restraint stress on the initiation of alcohol intake across 2 weeks of intermittent, two-bottle choice intake in male and female adolescent rats and adult female rats. Restraint stress significantly increased alcohol intake and preference in female adolescent rats but decreased alcohol intake and preference in male adolescent and female adult rats. The effects of restraint stress on alcohol intake were mitigated in adolescent females following administration of the κ opioid receptor antagonist norbinaltorphimine. Adolescent but not adult female rats that were subjected to restraint stress spent more time on the open arms of the elevated plus maze. Female adolescents exposed to stress also exhibited greater risk-taking behaviors in a concentric square field test compared with non-stressed controls. These results indicate age- and sex-related differences in the sensitivity to alcohol-stress interactions that may facilitate the initiation of alcohol use in female adolescents. The facilitatory effect of stress on alcohol intake was related to greater exploratory and risk-taking behaviors in young females after stress exposure. Copyright © 2017 Elsevier B.V.

  10. Sex determination in amphibians.

    The heterogametic sex is male in all mammals, whereas it is female in almost all birds. By contrast, there are two heterogametic types (XX/XY and ZZ/ZW) for genetic sex determination in amphibians. Though the original heterogametic sex was female in amphibians, the two heterogametic types were probably interchangeable, suggesting that sex chromosomes evolved several times in this lineage. Indeed, the frog Rana rugosa has the XX/XY and ZZ/ZW sex-determining systems within a single species, depending on the local population in Japan. The XY and ZW geographic forms with differentiated sex chromosomes probably have a common origin as undifferentiated sex chromosomes resulted from the hybridization between the primary populations of West Japan and Kanto forms. It is clear that the sex chromosomes are still undergoing evolution in this species group. Regardless of the presence of a sex-determining gene in amphibians, the gonadal sex of some species can be changed by sex steroids. Namely, sex steroids can induce the sex reversal, with estrogens inducing the male-to-female sex reversal, whereas androgens have the opposite effect. In R. rugosa, gonadal activity of CYP19 (P450 aromatase) is correlated with the feminization of gonads. Of particular interest is that high levels of CYP19 expression are observed in indifferent gonads at time before sex determination. Increases in the expression of CYP19 in female gonads and CYP17 (P450 17alpha-hydroxylase/C17-20 lyase) in male gonads suggest that the former plays an important role in phenotypic female determination, whereas the latter is needed for male determination. Thus, steroids could be the key factor for sex determination in R. rugosa. In addition to the role of sex steroids in gonadal sex determination in this species, Foxl2 and Sox3 are capable of promoting CYP19 expression. Since both the genes are autosomal, another factor up-regulating CYP19 expression must be recruited. The factor, which may be located on the X or W

    Human studies indicate that alcohol exposure during gestation not only increases the chance for later alcohol abuse, but also nicotine dependence. The flavor attributes of both alcohol and nicotine can be important determinants of their initial acceptance and they both share the component chemosensory qualities of an aversive odor, bitter taste and oral irritation. There is a growing body of evidence demonstrating epigenetic chemosensory mechanisms through which fetal alcohol exposure increases adolescent alcohol acceptance, in part, by decreasing the aversion to alcohol's bitter and oral irritation qualities, as well as its odor. Given that alcohol and nicotine have noteworthy chemosensory qualities in common, we investigated whether fetal exposure to alcohol increased the acceptability of nicotine's odor and taste in adolescent rats. Study rats were alcohol-exposed during fetal development via the dams' liquid diet. Control animals received ad lib access to an iso-caloric, iso-nutritive diet throughout gestation. Odorant-induced innate behavioral responses to nicotine odor (Experiment 1) or orosensory-mediated responses to nicotine solutions (Experiment 2) were obtained, using whole-body plethysmography and brief access lick tests, respectively. Compared to controls, rats exposed to fetal alcohol showed an enhanced nicotine odor response that was paralleled by increased oral acceptability of nicotine. Given the common aversive component qualities imbued in the flavor profiles of both drugs, our findings demonstrate that like postnatal alcohol avidity, fetal alcohol exposure also influences nicotine acceptance, at a minimum, by decreasing the aversion of both its smell and taste. Moreover, they highlight potential chemosensory-based mechanism(s) by which fetal alcohol exposure increases the later initial risk for nicotine use, thereby contributing to the co-morbid expression with enhanced alcohol avidity. Where common chemosensory mechanisms are at play, our

  13. Factors associated with undergraduate alcohol use

    1974-01-01

    To examine cigarette, alcohol, and drug use among undergraduates in Cork a precoded questionnaire was mailed to one in seven (458) students, chosen systematically. The response rate was 97%. Twenty per cent of males and 36% of females do not drink, whereas 52% of males and 17% of females are social drinkers or occasional drunks. Student patterns of drinking behaviour were significantly associated with sociocultural factors, such as leisure money available, belief in a God, and frequency of attendance at religious services. Current cigarette use, experience of marijuana, and attitude to future marijuana use, to the opposite sex drinking, and to the misdemeanour considered most serious also had significant associations with alcohol-related behaviour. It appears that peer group pressures, as illustrated by the proportion of close friends drinking and sibling drinking, have a greater influence on student drinking behaviour than family-related factors such as parental drinking and parental knowledge of drinking. The effect of ambivalent attitudes towards alcohol use, demonstrated by the age at introduction and the place of introduction to alcohol, may suggest that a more relaxed attitude to alcohol should be adopted.

    Alcohol is widely consumed; however, excessive use creates serious physical, psychological and social problems and contributes to the pathogenesis of many diseases. Alcohol use disorders (that is, alcohol dependence and alcohol abuse) are maladaptive patterns of excessive drinking that lead to serious problems. Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person's risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2. As more variants are analysed and studies are combined for meta-analysis to achieve increased sample sizes, an improved picture of the many genes and pathways that affect the risk of alcoholism will be possible.

    Rapid excessive alcohol drinking frequently causes disturbance of consciousness due to head trauma, brain edema, hypoglycemia, hyponatremia, hepatic coma and so on, provoked by acute alcohol intoxication. Rapid differential diagnosis and management are extremely important to save a life. On the other hands, the chronic users of alcohol so called alcoholism has many kinds of physical diseases such as liver diseases (i.e., fatty liver, alcoholic hepatitis, alcoholic liver cirrhosis and miscellaneous liver disease), diabetes mellitus, injury to happen in drunkenness, pancreas disease (i.e., acute and chronic pancreatitis and deterioration of chronic pancreatitis), gastrontestinal diseases (i.e., gastroduodenal ulcer), and so on. Enough attention should be paid to above mentioned diseases, otherwise they would turn worse more with continuation and increase in quantity of the alcohol. It should be born in its mind that the excessive drinking becomes the weapon threatening life.

    2016-01-01

    Full Text Available A method is proposed for solving single-period inventory fuzzy probabilistic model (SPIFPM with fuzzy demand and fuzzy storage space under a chance constraint. Our objective is to maximize the total profit for both overstock and understock situations, where the demand D~j for each product j in the objective function is considered as a fuzzy random variable (FRV and with the available storage space area W~, which is also a FRV under normal distribution and exponential distribution. Initially we used the weighted sum method to consider both overstock and understock situations. Then the fuzziness of the model is removed by ranking function method and the randomness of the model is removed by chance constrained programming problem, which is a deterministic nonlinear programming problem (NLPP model. Finally this NLPP is solved by using LINGO software. To validate and to demonstrate the results of the proposed model, numerical examples are given.

    One of the most important problems in the pharmacy department of a hospital is stock management. The clinical need for drugs must be satisfied with limited work labor while minimizing the use of economic resources. The complexity of the problem resides in the random nature of the drug demand and the multiple constraints that must be taken into account in every decision. In this article, chance-constrained model predictive control is proposed to deal with this problem. The flexibility of model predictive control allows taking into account explicitly the different objectives and constraints involved in the problem while the use of chance constraints provides a trade-off between conservativeness and efficiency. The solution proposed is assessed to study its implementation in two Spanish hospitals. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A double-sided fuzzy chance-constrained fractional programming (DFCFP) method is developed for planning water resources management under uncertainty. In DFCFP the system marginal benefit per unit of input under uncertainty can also be balanced. The DFCFP is applied to a real case of water resources management in the Zhangweinan River Basin, China. The results show that the amounts of water allocated to the two cities (Anyang and Handan) would be different under minimum and maximum reliability degrees. It was found that the marginal benefit of the system solved by DFCFP is bigger than the system benefit under the minimum and maximum reliability degrees, which not only improve economic efficiency in the mass, but also remedy water deficiency. Compared with the traditional double-sided fuzzy chance-constrained programming (DFCP) method, the solutions obtained from DFCFP are significantly higher, and the DFCFP has advantages in water conservation.

    Since facility location decisions problem include long-term character and potential parameter variations, it is important to consider uncertainty in its modeling. This paper examines robust facility location problem considering supply uncertainty, in which we assume the supply of the facility in the actual operation is not equal to the supply initially established, the supply is subject to random fluctuation. The chance constraints are introduced when formulating the robust facility location model to make sure the system operate properly with a certain probability while the supply fluctuates. The chance constraints are approximated safely by using Hoeffding's inequality and the problem is transformed to a general deterministic linear programming. Furthermore, how the facility location cost change with confidence level is investigated through a numerical example. The sensitivity analysis is conducted for important parameters of the model and we get the main factors that affect the facility location cost.

    Full Text Available We solve a linear chance constrained portfolio optimization problem using Robust Optimization (RO method wherein financial script/asset loss return distributions are considered as extreme valued. The objective function is a convex combination of portfolio’s CVaR and expected value of loss return, subject to a set of randomly perturbed chance constraints with specified probability values. The robust deterministic counterpart of the model takes the form of Second Order Cone Programming (SOCP problem. Results from extensive simulation runs show the efficacy of our proposed models, as it helps the investor to (i utilize extensive simulation studies to draw insights into the effect of randomness in portfolio decision making process, (ii incorporate different risk appetite scenarios to find the optimal solutions for the financial portfolio allocation problem and (iii compare the risk and return profiles of the investments made in both deterministic as well as in uncertain and highly volatile financial markets.

    2016-08-01

    This article introduces an inexact fuzzy integer chance constraint programming (IFICCP) approach for identifying noise reduction strategy under uncertainty. The IFICCP method integrates the interval programming and fuzzy chance constraint programming approaches into a framework, which is able to deal with uncertainties expressed as intervals and fuzziness. The proposed IFICCP model can be converted into two deterministic submodels corresponding to the optimistic and pessimistic conditions. The modelling approach is applied to a hypothetical control measure selection problem for noise reduction. Results of the case study indicate that useful solutions for noise control practices can be acquired. Three acceptable noise levels for two communities are considered. For each acceptable noise level, several decision alternatives have been obtained and analysed under different fuzzy confidence levels, which reflect the trade-offs between environmental and economic considerations.

    2014-12-01

    Full Text Available In order to maintain the stability and security of the power system, the uncertainty and intermittency of wind power must be taken into account in economic dispatch (ED problems. In this paper, a dynamic economic dispatch (DED model based on chance constrained programming is presented and an improved particle swarm optimization (PSO approach is proposed to solve the problem. Wind power is regarded as a random variable and is included in the chance constraint. New formulation of up and down spinning reserve constraints are presented under expectation meaning. The improved PSO algorithm combines a feasible region adjustment strategy with a hill climbing search operation based on the basic PSO. Simulations are performed under three distinct test systems with different generators. Results show that both the proposed DED model and the improved PSO approach are effective.

    The seat belt syndrome is a recognised complication of seat belt use in vehicles. Unstable Chance fractures of the spine without neurological deficits have been reported infrequently. We describe a young woman with completely disrupted Chance fracture of the second lumbar vertebra in association with left hemidiaphragmatic rupture/hernia, multiple bowel perforations, splenic capsular tear, left humeral shaft and multiple rib fractures. These injuries which resulted from high-speed vehicle collision and led to death of one of the occupants were readily detected by trauma series imaging. The patient was successfully treated by a dedicated multidisciplinary team which adopted a staged surgical approach and prioritisation of care. There were no manifested neurological or other deficits after 1 year of follow-up. To the authors' knowledge, this is the first report of such a case in Australasia. We discuss the challenging surgical management, highlighting the role of radiological imaging in such cases and provide a literature review.

  7. Alcohol disrupts sleep homeostasis.

    2015-06-01

    Alcohol is a potent somnogen and one of the most commonly used "over the counter" sleep aids. In healthy non-alcoholics, acute alcohol decreases sleep latency, consolidates and increases the quality (delta power) and quantity of NREM sleep during the first half of the night. However, sleep is disrupted during the second half. Alcoholics, both during drinking periods and during abstinences, suffer from a multitude of sleep disruptions manifested by profound insomnia, excessive daytime sleepiness, and altered sleep architecture. Furthermore, subjective and objective indicators of sleep disturbances are predictors of relapse. Finally, within the USA, it is estimated that societal costs of alcohol-related sleep disorders exceeds $18 billion. Thus, although alcohol-associated sleep problems have significant economic and clinical consequences, very little is known about how and where alcohol acts to affect sleep. In this review, we have described our attempts to unravel the mechanism of alcohol-induced sleep disruptions. We have conducted a series of experiments using two different species, rats and mice, as animal models. We performed microdialysis, immunohistochemical, pharmacological, sleep deprivation and lesion studies which suggest that the sleep-promoting effects of alcohol may be mediated via alcohol's action on the mediators of sleep homeostasis: adenosine (AD) and the wake-promoting cholinergic neurons of the basal forebrain (BF). Alcohol, via its action on AD uptake, increases extracellular AD resulting in the inhibition of BF wake-promoting neurons. Since binge alcohol consumption is a highly prevalent pattern of alcohol consumption and disrupts sleep, we examined the effects of binge drinking on sleep-wakefulness. Our results suggest that disrupted sleep homeostasis may be the primary cause of sleep disruption observed following binge drinking. Finally, we have also shown that sleep disruptions observed during acute withdrawal, are caused due to impaired

  8. Sex, epilepsy, and epigenetics.

    Epilepsy refers to a heterogeneous group of disorders that are associated with a wide range of pathogenic mechanisms, seizure manifestations, comorbidity profiles, and therapeutic responses. These characteristics are all influenced quite significantly by sex. As with other conditions exhibiting such patterns, sex differences in epilepsy are thought to arise-at the most fundamental level-from the "organizational" and "activational" effects of sex hormones as well as from the direct actions of the sex chromosomes. However, our understanding of the specific molecular, cellular, and network level processes responsible for mediating sex differences in epilepsy remains limited. Because increasing evidence suggests that epigenetic mechanisms are involved both in epilepsy and in brain sexual dimorphism, we make the case here that analyzing epigenetic regulation will provide novel insights into the basis for sex differences in epilepsy.

    Alcohol-related crime is increasingly being recognized as a problem in cities and towns with popular entertainment districts. Crime and disorder linked to alcohol has been particularly connected with binge drinking or heavy sessional drinking. Research evidence indicates that it is the young adult age group who are most likely to be involved in crime and disorder and the most likely to binge drink. This paper examines the relationship between binge drinking and criminal and disorderly behaviour among 18- to 24-year-olds. Secondary analysis was undertaken of the 1998/1999 Youth Lifestyles Survey, a large-scale, representative, household survey of 12- to 30-year-olds living in England and Wales. Binge drinking, and especially male binge drinking, among 18- to 24-year-olds is statistically related to offending behaviour. In the 12 months prior to interview 39% of binge drinkers admitted to committing an offence and 60% admitted criminal and/or disorderly behaviour during or after drinking alcohol. Multivariate analysis found that binge drinking remains strongly associated with criminal and disorderly behaviour even after taking other relevant factors into account. Individuals who got drunk at least once a week had more than five times the odds of being involved in fighting or violent crime. For offences or disorderly behaviour that took place during or after drinking alcohol an individual had a seven times greater chance of breaking or damaging something and a five times greater chance of being involved in a fight if he/she got drunk at least once a week. These findings suggest that frequency of drunkenness is a better predictor of offending behaviour than frequency of drinking per se. Using frequency of drunkenness as the basis for defining binge drinking reveals that a large minority of young adults who binge drink also become involved in offending or disorderly behaviour. Binge drinking is particularly associated with crimes of violence. The relationship between

    Several recent studies have described a strong correlation between nutritional or economic data and the number of Nobel awards obtained across a large range of countries.

    The single transferable vote system of proportional representation as operated in elections to Dail Eireann is one of the most sophisticated electoral systems, maximising the capacity of the voter to determine the outcome of an election and allowing multi-dimensional representation of party political and other interests. Its most significant drawback is the fact that it retains an element of chance in certain circumstances, although this has been reduced to insignificance in the comparable el...

    Full Text Available Analisar os determinantes dos desempenhos de candidatos ao concurso vestibular da UFC constitui-se o foco central deste artigo. A metodologia baseou-se em uma função de produção de rendimento educacional e estimação feita por modelos econométricos de escolha discreta, dicotômico e policotômico, com o fito de se extrair as chances de os candidatos lograrem êxito em todas as áreas do concurso. Para tanto, foi utilizada uma base de dados derivada de questionários socioeconômicos dos candidatos, e disponibilizados pela Pró-Reitoria de Graduação da UFC. Dos resultados estatisticamente robustos, constatou-se no vetor de variáveis socioeconômicas um forte efeito negativo na chance de sucesso no vestibular para aqueles candidatos que se encontram no mercado de trabalho. Background familiar foi incisivo sobre os sucessos dos candidatos, vez que aqueles que possuem pais com nível superior demonstram possuir melhor performance no exame. A qualidade do ensino público de nível médio transpareceu nos resultados ao reduzir sobremaneira as chances de êxito para os candidatos advindos de escolas públicas. Analisando-se os desempenhos por área, concluiu-se, dentro de cenários de previsão, que candidatos com elevada chance de sucesso em determinada área não a manteria em outras áreas. Descartou-se o efeito concorrência como determinante do desempenho em cada área.

    Epilepsy refers to a heterogeneous group of disorders that are associated with a wide range of pathogenic mechanisms, seizure manifestations, comorbidity profiles, and therapeutic responses. These characteristics are all influenced quite significantly by sex. As with other conditions exhibiting such patterns, sex differences in epilepsy are thought to arise—at the most fundamental level—from the “organizational” and “activational” effects of sex hormones as well as from the direct actions of ...

  18. The Relationship between Alcohol Outlets, HIV Risk Behavior, and HSV-2 Infection among South African Young Women: A Cross-Sectional Study.

    Full Text Available Alcohol consumption has a disinhibiting effect that may make sexual risk behaviors and disease transmission more likely. The characteristics of alcohol-serving outlets (e.g. music, dim lights, lack of condoms may further encourage risky sexual activity. We hypothesize that frequenting alcohol outlets will be associated with HIV risk.In a sample of 2,533 school-attending young women in rural South Africa, we performed a cross-sectional analysis to examine the association between frequency of alcohol outlet visits in the last six months and four outcomes related to HIV risk: number of sex partners in the last three months, unprotected sex acts in the last three months, transactional sex with most recent partner, and HSV-2 infection. We also tested for interaction by alcohol consumption.Visiting alcohol outlets was associated with having more sex partners [adjusted odds ratio (aOR, one versus zero partners (95% confidence interval (CI: 1.51 (1.21, 1.88], more unprotected sex acts [aOR, one versus zero acts (95% CI: 2.28 (1.52, 3.42], higher levels of transactional sex [aOR (95% CI: 1.63 (1.03, 2.59], and HSV-2 infection [aOR (95% CI: 1.30 (0.88, 1.91]. In combination with exposure to alcohol consumption, visits to alcohol outlets were more strongly associated with all four outcomes than with either risk factor alone. Statistical evidence of interaction between alcohol outlet visits and alcohol consumption was observed for all outcomes except transactional sex.Frequenting alcohol outlets was associated with increased sexual risk in rural South African young women, especially when they consumed alcohol. Sexual health interventions targeted at alcohol outlets may effectively reach adolescents at high risk for sexually transmitted infections like HIV and HSV-2.HIV Prevention Trials Network HPTN 068.

    The FMR1 gene partially appears to control ovarian reserve, with a specific ovarian sub-genotype statistically associated with a polycystic ovary (PCO)- like phenotype. Some forms of PCO have been associated with autoimmunity. We, therefore, investigated in multiple regression analyses associations of ovary-specific FMR1 genotypes with autoimmunity and pregnancy chances (with in vitro fertilization, IVF) in 339 consecutive infertile women (455 IVF cycles), 75 with PCO-like phenotype, adjusted for age, race/ethnicity, medication dosage and number of oocytes retrieved. Patients included 183 (54.0%) with normal (norm) and 156 (46%) with heterozygous (het) FMR1 genotypes; 133 (39.2%) demonstrated laboratory evidence of autoimmunity: 51.1% of het-norm/low, 38.3% of norm and 24.2% het-norm/high genotype and sub-genotypes demonstrated autoimmunity (p=0.003). Prevalence of autoimmunity increased further in PCO-like phenotype patients with het-norm/low genotype (83.3%), remained unchanged with norm (34.0%) and decreased in het-norm/high women (10.0%; PPregnancy rates were significantly higher with norm (38.6%) than het-norm/low (22.2%, p=0.001). FMR1 sub-genotype het-norm/low is strongly associated with autoimmunity and decreased pregnancy chances in IVF, reaffirming the importance of the distal long arm of the X chromosome (FMR1 maps at Xq27.3) for autoimmunity, ovarian function and, likely, pregnancy chance with IVF.

    Full Text Available Alcohol exerts teratogenic effects in all the gestation times, with peculiar features in relationship to the trimester of pregnancy in which alcohol is assumed. Alcohol itself and its metabolites modify DNA synthesis, cellular division, cellular migration and the fetal development. The characteristic facies of feto-alcoholic syndrome (FAS-affected baby depends on the alcohol impact on skull facial development during the first trimester of pregnancy. In association there are cerebral damages with a strong defect of brain development up to the life incompatibility. Serious consequences on fetal health also depends on dangerous effects of alcohol exposure in the organogenesis of the heart, the bone, the kidney, sensorial organs, et al. It has been demonstrated that maternal binge drinking is a high factor risk of mental retardation and of delinquent behaviour. Unfortunately, a lower alcohol intake also exerts deleterious effects on fetal health. In several countries of the world there is a high alcohol use, and this habit is increased in the women. Therefore, correct information has to be given to avoid alcohol use by women in the preconceptional time and during the pregnancy. Preliminary results of a study performed by the authors show that over 80% of pregnant and puerperal women are not unaware that more than 2 glasses of alcohol/week ingested during pregnancy can create neurological abnormalities in the fetus. However, after the information provided on alcoholic fetopathy, all women are conscious of the damage caused by the use of alcohol to the fetus during pregnancy. This study confirms the need to provide detailed information on the negative effects of alcohol on fetal health. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    Full Text Available Abstract Background The risk environment framework provides a valuable but under-utilised heuristic for understanding environmental vulnerability to HIV and other sexually transmitted infections among female sex workers. Brothels have been shown to be safer than street-based sex work, with higher rates of consistent condom use and lower HIV prevalence. While entertainment venues are also assumed to be safer than street-based sex work, few studies have examined environmental influences on vulnerability to HIV in this context. Methods As part of the Young Women's Health Study, a prospective observational study of young women (15-29 years engaged in sex work in Phnom Penh, we conducted in-depth interviews (n = 33 to explore vulnerability to HIV/STI and related harms. Interviews were conducted in Khmer by trained interviewers, transcribed and translated into English and analysed for thematic content. Results The intensification of anti-prostitution and anti-trafficking efforts in Cambodia has increased the number of women working in entertainment venues and on the street. Our results confirm that street-based sex work places women at risk of HIV/STI infection and identify significant environmental risks related to entertainment-based sex work, including limited access to condoms and alcohol-related intoxication. Our data also indicate that exposure to violence and interactions with the police are mediated by the settings in which sex is sold. In particular, transacting sex in environments such as guest houses where there is little or no oversight in the form of peer or managerial support or protection, may increase vulnerability to HIV/STI.

    The objective of this study was to study factors affecting a reproductive performance indicator at the cow level adjusted for herd management strategy. Associations between the outcome variable, pregnant or not at the herd voluntary waiting period (VWP) plus 30d (pregnant at VWP+30), and the predictor variables were analyzed using a multivariable, generalized estimation equations model that adjusted for clustering of the data at the herd level. The statistical analysis was stratified on parity. In total, 132,721 cows were retained for analyses, of which 29,113 (22%) were pregnant at VWP+30d. Of the nonpregnant cows, 81,483 cows had records of artificial inseminations (AI) and 22,125 cows had no records of AI. The chance of pregnancy was higher for cows of the Swedish Red and for other/crossbreeds compared with Swedish Holstein, for cows from herds with high heat detection efficiency compared with cows from herds with medium and low heat detection efficiency, for cows from herds with long VWP (i.e., >51d) compared with cows from herds with short VWP (cows in freestalls compared with cows in tiestalls. The chance for pregnancy was lower for cows with severe problems at claw trimming compared with cows with no problems at trimming (only for second- and higher-parity cows), for cows that had a record of reproduction-related disease, for cows that had a record of any other disease compared with cows without record, for second- and higher-parity cows with records of dystocia compared with cows with no record of dystocia, for first-parity cows in the group with the highest milk yield compared with first-parity cows in the group with the lowest milk yield, for cows of third and higher parity in the group with the lowest milk yield compared with cows in higher yielding groups, for cows bred in summer compared with those bred in winter-spring (not significant for first-parity cows), and for cows with a twin birth had compared with cows with a single birth.

  7. Plant Sex Determination.

    Sex determination is as important for the fitness of plants as it is for animals, but its mechanisms appear to vary much more among plants than among animals, and the expression of gender in plants differs in important respects from that in most animals. In this Minireview, I provide an overview of the broad variety of ways in which plants determine sex. I suggest that several important peculiarities of plant sex determination can be understood by recognising that: plants show an alternation of generations between sporophytic and gametophytic phases (either of which may take control of sex determination); plants are modular in structure and lack a germ line (allowing for a quantitative expression of gender that is not common in animals); and separate sexes in plants have ultimately evolved from hermaphroditic ancestors. Most theorising about sex determination in plants has focused on dioecious species, but we have much to learn from monecious or hermaphroditic species, where sex is determined at the level of modules, tissues or cells. Because of the fundamental modularity of plant development and potentially important evolutionary links between monoecy and dioecy, it may be useful to relax the distinction often made between 'developmental sex determination' (which underpins the development of male versus female flowers in monoecious species) and 'genetic sex determination' (which underpins the separation of males and females in dioecious species, often mediated by a genetic polymorphism and sex chromosomes). I also argue for relaxing the distinction between sex determination involving a genetic polymorphism and that involving responses to environmental or hormonal cues, because non-genetic cues might easily be converted into genetic switches.

  8. Sex tourism in Thailand.

    Many foreigners visit Thailand in search of sex. While long-distance tourism was long enjoyed by members of more privileged social classes, even the lower economical classes of Japan, Malaysia, Europe, America, and Australia can now afford to travel over long distances. This relatively new breed of tourist is more likely to be of lower socioeconomic and educational status and less likely to use condoms when having sex. An estimated 30,000 sex workers are active in Bangkok, of whom 7000/10,000 are females who work specifically in the tourism sector. 1/2-1/3 of the 600 commercial sex establishments in the city are visited by foreigners. Phuket, Pattaya, Koh Samui, and Chiangmai are also well-frequented by sex tourists. Overall, a large, diverse, inexpensive, and accessible commercial sex market exists in Thailand. One may meet sex workers quasi-ubiquitously and be assured to find someone capable of meeting one's sexual needs. With these attributes, Thailand strongly attracts tourists in search of sex. A certain degree of recklessness also prevails among those on vacation. Away from the peers and social mores of their native lands, tourists may engage in sexually activities without criticism. Likewise, Thai sex workers who cater to foreigners, especially females, enjoy more freedom and control in sexual relations than their peers who work among nationals. Neither single nor married women in Thailand are allowed much sexual freedom and are traditionally expected to be obliging docile, and submissive. The greater than normal personal latitude enjoyed by both sex worker and foreigner lead to more negotiation on condom use and overall lower use. As such, Thailand's commercial sex market with foreigners' involvement therein threatens to spread HIV to many other countries throughout the world.

    Alcohol consumption is a major cause of disease and death. In a previous study, we reported that in 2002, 3.6% of all cases of cancer and a similar proportion of cancer deaths were attributable to the consumption of alcohol. We aimed to update these figures to 2012 using global estimates of cancer cases and cancer deaths, data on the prevalence of drinkers from the World Health Organization (WHO) global survey on alcohol and health, and relative risks for alcohol-related neoplasms from a recent meta-analysis. Over the 10-year period considered, the total number of alcohol-attributable cancer cases increased to approximately 770,000 worldwide (5.5% of the total number of cancer cases)-540,000 men (7.2%) and 230,000 women (3.5%). Corresponding figures for cancer deaths attributable to alcohol consumption increased to approximately 480,000 (5.8% of the total number of cancer deaths) in both sexes combined-360,000 (7.8%) men and 120,000 (3.3%) women. These proportions were particularly high in the WHO Western Pacific region, the WHO European region and the WHO South-East Asia region. A high burden of cancer mortality and morbidity is attributable to alcohol, and public health measures should be adopted in order to limit excessive alcohol consumption.

    In this chapter, we review the effects of global null mutant and overexpressing transgenic mouse lines on voluntary self-administration of alcohol. We examine approximately 200 publications pertaining to the effects of 155 mouse genes on alcohol consumption in different drinking models. The targeted genes vary in function and include neurotransmitter, ion channel, neuroimmune, and neuropeptide signaling systems. The alcohol self-administration models include operant conditioning, two- and four-bottle choice continuous and intermittent access, drinking in the dark limited access, chronic intermittent ethanol, and scheduled high alcohol consumption tests. Comparisons of different drinking models using the same mutant mice are potentially the most informative, and we will highlight those examples. More mutants have been tested for continuous two-bottle choice consumption than any other test; of the 137 mouse genes examined using this model, 97 (72%) altered drinking in at least one sex. Overall, the effects of genetic manipulations on alcohol drinking often depend on the sex of the mice, alcohol concentration and time of access, genetic background, as well as the drinking test.

    Full Text Available Objective: To describe the health practices adopted by sex workers in their daily lives. Methods: A qualitative study that took place at bars where sex workers of Maceió –AL, Brazil, work. The universe of participant subjects was integrated by 15 female sex workers, aged between 20 and 39 years, assisted by the team of a Street Clinic. The research took place between August and October 2011 and women were randomly selected. Data was collected through semi-structured interviews, which were all audio-recorded and transcribed for further analysis and interpretation. Results: Thematic analysis of the data produced and the theoretical framework of health promotion enabled the categorization of the health practices in daily life of these women, such as: prevention of sexually transmitted diseases, body care and aesthetics, physical activity, nutrition, leisure, interpersonal relationships, consumption of alcohol and others drugs, self-medication, and quest for health services. The ways they appropriate themselves of such practices are conditioned by the social vulnerability and economic and sociocultural context they are in. Conclusion: Despite the deficiencies found in the development of these practices, sex workers seek to preserve habits that improve their physical, social and mental health, as well as the pursuit of professional care and services to promote their health.

    Alcohol use has been linked to risky sexual practices among adolescents. However, limited research on alcohol use and risky sexual behavior has been conducted among female adolescents. This study examined a high quantity of alcohol as a longitudinal predictor of risky sexual behavior and sexually transmitted diseases (STDs) among female adolescents. Three hundred ninety-three adolescent females aged 15-21 were assessed for alcohol use and risky sexual behaviors. Participants also provided 2 swab specimens that were assayed for STDs. Use of high alcohol quantity was defined as > or = 3 drinks in 1 sitting. Binary generalized estimating equation models were conducted assessing the impact of alcohol use at baseline on risky sexual behavior and STDs over a 12-month period. Age, intervention group and baseline outcome measures were entered as covariates. The results indicated that use of high alcohol quantity predicted inconsistent condom use, high sexual sensation seeking, multiple sexual partners, sex while high on alcohol or drugs, and having anal sex during 12-month follow-up period. These findings suggest that STD-related behavioral interventions for adolescents should discuss the link between alcohol and STD-risk behavior. Deeper understanding of alcohol as a predictor of risky sexual behavior among female adolescents is of paramount importance for development of efficient prevention programs at individual and community levels. The risk of acquiring an STD is higher among teenagers than among adults.

    Alcoholism and alcohol-associated organ injury is one of the major health problems worldwide. Alcohol may lead to an alteration in intermediary metabolism and the relation between alcohol intake and body weight is a paradox. The effect of alcohol intake on resting metabolic rate, assessed by indirect calorimetry, and lipid oxidation, is still controversial. Small quantities of ethanol seem to have no effect on body weight. Ingestion of moderate amounts may lead to an increase in body weight, via a lipid-oxidizing suppressive effect. Chronic intake of excessive amounts in alcoholics leads to a decrease in body weight, probably via increased lipid oxidation and energy expenditure. Chronic ethanol abuse alters lipid-soluble (vitamins A, D and E) and water-soluble (B-complex vitamins, vitamin C) vitamins status, and some trace elements status such as magnesium, selenium or zinc.

    Problematic use of alcohol configures an element of interest in the context of preventive interventions aimed to ensuring the performance of any work in safety conditions. To contrast the acute alcohol abuse in the workplace the existing legislation provides alcoholimeters controls and prohibition of recruitment and administration of alcohol. Recent legislation (D.Lgs. 81/08) establishes health surveillance for alcohol dependence and appears still incomplete and difficult to apply. Clinical diagnostic tools available to the physician for alcohol dependence identification are well-defined and recently improved thanks to new laboratory markers with high sensitivity and specificity (CDT) and self-administered questionnaires. In this contest we are awaiting for legislative action to specify conditions and procedures for inspections in the workplace in order to face the problem of alcohol dependence without excessive bureaucracy and with more attention to preventive aspects.

    Full Text Available Background: The association between alcohol and aggression has long been recognized, but the systematic research to understand the causal basis for this relationship and the processes that underlie it has only been undertaken in the past 25 years. In the article the most important mechanisms, by which alcohol affects behavior, are explained. Aggression in persons with alcohol dependence and the connection between antisocial (dissocial personality disorder, alcohol and aggression are described. In addition different forms of aggression or violence, that have been committed under the influence of alcohol, such as inter-partner violence, sexual assault, child abuse, crime and traffic accidents are described.Conclusions: The research findings can be used in the prevention and treatment of alcohol-related aggression.

  2. Alcohol and atherosclerosis

    Full Text Available Observational studies have attributed a protective effect to alcohol consumption on the development of atherosclerosis and cardiovascular morbidity and mortality. Alcohol intake in the amount of one to two drinks per day results in an estimated 20-40% reduction in cardiovascular events. An additional protective effect, according to major cohort studies, has been attributed to wine, probably due to antioxidant effects and platelet antiaggregation agents. On the other hand, the influence of different patterns of alcohol consumption and environmental factors may explain a great part of the additional effect of wine. Protection may be mediated by modulation of other risk factors, because alcohol increases HDL-C, produces a biphasic response on blood pressure, and modulates the endothelial function, while it neither increases body weight nor impairs glucose-insulin homeostasis. Alcohol may also have a direct effect on atherogenesis. Despite these favorable effects, the current evidence is not enough to justify prescribing alcohol to prevent cardiovascular disease.

    Although sex differences in several aspects of substance use disorders (SUDs) have been identified, less is known about the importance of possible sex differences in side effects induced by substances of abuse or by medications used to treat SUDs. In the SUD field, the perception of certain subjective effects are actively sought, while all other manifestations might operationally be considered side effects. This article was aimed at reviewing sex differences in side effects induced by alcohol, nicotine, heroin, marijuana and cocaine and by medications approved for alcohol, nicotine and heroin use disorders. A large body of evidence suggests that women are at higher risk of alcohol-induced injury, liver disease, cardiomyopathy, myopathy, brain damages and mortality. The risk of tobacco-induced coronary heart disease, lung disease and health problems is higher for women than for men. Women also experience greater exposure to side effects induced by heroin, marijuana and cocaine. In addition, women appear to be more vulnerable to the side effects induced by medications used to treat SUDs. Patients with SUDs should be advised that the risk of developing health problems may be higher for women than for men after consumption of the same amount of substances of abuse. Doses of medications for SUD women should be adjusted at least according to body weight. The sex differences observed also indicate an urgent need to recruit adequate numbers of female subjects in pre-clinical and clinical studies to improve our knowledge about SUDs in women.

    To investigate the sex-hormone profiles associated with chronic alcoholism in women we examined 16 non-cirrhotic alcohol abusers (aged 18-46 years). They were admitted for the treatment of alcoholism (duration of 2-16 yrs) to a social hospital for 6 weeks. Their mean daily alcohol consumption was 170 g. Blood samples for serum LH, FSH, prolactin (PRL), oestrone (E1), oestradiol (E2), progesterone (P), 17-alpha-hydroxyprogesterone (17-OHP), androstenedione (A) and dehydroepiandrosterone (DHEA) were drawn three times a week during the hospital stay. Similar blood samples were taken from 10 control women during one menstrual cycle. The cycles were anovulatory in two patients and in none of controls. Serum LH and FSH levels were similar in alcoholic and control women but serum concentrations of PRL were increased 2-4-fold in alcoholic women. In the patients serum, concentrations of E1 and E2 tended to be lower during the follicular and midcycle phases, as did those of P and 17-OHP during the luteal phase. Compared with the controls, serum levels of A were increased 2-3-fold in the patients. A parallel difference between the two groups was seen in serum DHEA concentrations. We conclude that until liver injury, even heavy alcohol drinking has only minor effects on the secretion of gonadotrophins and ovarian steroids. Hypersecretion of PRL and adrenal androgens may well be an initiating mechanism for sexual dysfunction of female alcoholics.

  9. Alcohol-Induced Blackout

    2009-11-01

    Full Text Available For a long time, alcohol was thought to exert a general depressant effect on the central nervous system (CNS. However, currently the consensus is that specific regions of the brain are selectively vulnerable to the acute effects of alcohol. An alcohol-induced blackout is the classic example; the subject is temporarily unable to form new long-term memories while relatively maintaining other skills such as talking or even driving. A recent study showed that alcohol can cause retrograde memory impairment, that is, blackouts due to retrieval impairments as well as those due to deficits in encoding. Alcoholic blackouts may be complete (en bloc or partial (fragmentary depending on severity of memory impairment. In fragmentary blackouts, cueing often aids recall. Memory impairment during acute intoxication involves dysfunction of episodic memory, a type of memory encoded with spatial and social context. Recent studies have shown that there are multiple memory systems supported by discrete brain regions, and the acute effects of alcohol on learning and memory may result from alteration of the hippocampus and related structures on a cellular level. A rapid increase in blood alcohol concentration (BAC is most consistently associated with the likelihood of a blackout. However, not all subjects experience blackouts, implying that genetic factors play a role in determining CNS vulnerability to the effects of alcohol. This factor may predispose an individual to alcoholism, as altered memory function during intoxication may affect an individual‟s alcohol expectancy; one may perceive positive aspects of intoxication while unintentionally ignoring the negative aspects. Extensive research on memory and learning as well as findings related to the acute effects of alcohol on the brain may elucidate the mechanisms and impact associated with the alcohol- induced blackout.

  10. Affordability of alcohol and alcohol-related mortality in Belarus.

    Alcohol abuse has numerous adverse health and social consequences. The consumer response to changes in alcohol affordability is an important issue on alcohol policy debates. Studies from many countries have shown an inverse relationship between alcohol prices and alcohol consumption in the population. There are, however, suggestions that increasing the price of alcohol by rising taxes may have limited effect on alcohol-related problems, associated with long-term heavy drinking. The aim of the present study was to evaluate the relationship between alcohol affordability and alcohol-related mortality rates in post-Soviet Belarus. For this purpose trends in alcohol-related mortality rates (mortality from liver cirrhosis, pancreatitis, alcoholism and alcohol psychoses) and affordability of vodka between 1990 and 2010 were compared. The time series analysis revealed that 1% increase in vodka affordability is associated with an increase in liver cirrhosis mortality of 0,77%, an increase in pancreatitis mortality of 0.53%, an increase in mortality from alcoholism and alcohol psychoses of 0,70%. The major conclusion emerging from this study is that affordability of alcohol is one of the most important predictor of alcohol-related problems in a population. These findings provide additional evidence that decreasing in affordability of alcohol is an effective strategy for reducing alcohol consumption and alcohol-related harm.

    Monitors of transdermal alcohol concentration (TAC) provide an objective measurement of alcohol consumption that is less invasive than measurements in blood, breath or urine; however, there is a substantial time delay in the onset of TAC compared to blood or breath alcohol concentrations (BrACs). The current study examined the characteristics of the delay between peak TAC and peak BrAC. Data was aggregated from three experimental laboratory studies (N = 61; 32 men, 29 women) in which participants wore a TAC monitor and BrAC was monitored while drinking one, two, three, four and five beers in the laboratory. Analyses examined the sex- and dose-related differences in peak BrAC and TAC, the time-to-peak BrAC and TAC, and time lag between the peak BrAC and TAC values. The times-to-peak were an increasing function of the number of beers consumed. At each level of beer consumption the peak TAC averaged lower than peak BrAC and times-to-peak TAC were longer than for BrAC. The time-to-peak BrAC and TAC was longer for women than men. The congruence between peak TAC and BrAC increased as a function of the beers consumed. No sex difference in the time lag between peak BrAC and TAC was detected. The congruence between TAC and BrAC and time lags between TAC and BrAC are related to the number of beers consumed. Peak values of TAC and BrAC became more congruent with higher doses but the time lag increased as a function of the amount of alcohol consumed. The time delay (or lag) and congruence between transdermal vs. BrACs increases as the number of beers increases. Though sex differences are evident in peak transdermal and BrACs, no sex differences were evident in the time lag and the congruence between transdermal and breath alcohol concentrations. © The Author 2016.

    2016-12-01

    Suffering related to dementia is multifaceted because cognitive and physical functioning slowly deteriorates. Advanced age and sex, two of the most prominent risk factors for dementia, are not modifiable. Lifestyle factors such as smoking, excessive alcohol use, and poor diet modulate susceptibility to dementia in both males and females. The degree to which the resulting health conditions (eg, obesity, type 2 diabetes, and cardiovascular disease) impact dementia risk varies by sex. Depending on the subtype of dementia, the ratio of male to female prevalence differs. For example, females are at greater risk of developing Alzheimer disease dementia, whereas males are at greater risk of developing vascular dementia. This review examines sex and gender differences in the development of dementia with the goal of highlighting factors that require further investigation. Considering sex as a biological variable in dementia research promises to advance our understanding of the pathophysiology and treatment of these conditions.

    The use of alcohol by adolescents is a growing problem and has become an important research topic in the etiology of the alcohol use disorders. A key component of this research has been the development of animal models of adolescent alcohol consumption and alcohol response. Due to their extended period of adolescence, rhesus macaques are especially well-suited for modeling alcohol-related phenotypes that contribute to the adolescent propensity for alcohol consumption. In this review, we discuss studies from our laboratory that have investigated both the initial response to acute alcohol administration and the consumption of alcohol in voluntary self-administration paradigms in adolescent rhesus macaques. These studies confirm that adolescence is a time of dynamic change both behaviorally and physiologically, and that alcohol response and alcohol consumption are influenced by life history variables such as age, sex, and adverse early experience in the form of peer-rearing. Furthermore, genetic variants that alter functioning of the serotonin, endogenous opioid, and corticotropin releasing hormone systems are shown to influence both physiological and behavioral outcomes, in some cases interacting with early experience to indicate gene by environment interactions. These findings highlight several of the pathways involved in alcohol response and consumption, namely reward, behavioral dyscontrol, and vulnerability to stress, and demonstrate a role for these pathways during the early stages of alcohol exposure in adolescence.

    The zebrafish has been proposed for modeling fetal alcohol spectrum disorders (FASD). Previous FASD research with zebrafish employed high concentrations of alcohol and/or long exposure periods. Here, we exposed zebrafish eggs to low doses of alcohol (0, 0.25, 0.50, 0.75 and 1.0% (vol/vol); external bath application of which 1/20th may reach the inside of the egg) at 16-h post-fertilization (hpf) and only for a short duration (2h) in the hope to avoid gross morphological aberrations and to mimic the more frequent FASD exposure levels. Upon reaching adulthood the exposed and control zebrafish were tested for their associative learning performance in a plus-maze. Embryonic alcohol exposure led to no gross anatomical abnormalities and did not increase mortality. Unexposed (control) zebrafish showed excellent acquisition of association between a conditioned visual stimulus (CS) and food reward, demonstrated by their preference for the target zone of the maze that contained the CS during a probe trial in the absence of reward. However, alcohol-exposed fish showed no such preference and performed indistinguishable from random chance. Locomotor activity during training and the probe trial or the amount of food consumed during training did not differ between the embryonic alcohol exposed and unexposed (control) fish, suggesting that the impaired learning performance found was unlikely to be caused by altered motivation or motor function. Our results suggest that even very small amounts of alcohol reaching the embryo for only a short duration of time may have long lasting deleterious effects on cognitive function in vertebrates.

    Full Text Available The FMR1 gene partially appears to control ovarian reserve, with a specific ovarian sub-genotype statistically associated with a polycystic ovary (PCO- like phenotype. Some forms of PCO have been associated with autoimmunity. We, therefore, investigated in multiple regression analyses associations of ovary-specific FMR1 genotypes with autoimmunity and pregnancy chances (with in vitro fertilization, IVF in 339 consecutive infertile women (455 IVF cycles, 75 with PCO-like phenotype, adjusted for age, race/ethnicity, medication dosage and number of oocytes retrieved.

Prevalence of autoimmunity increased further in PCO-like phenotype patients with het-norm/low genotype (83.3%, remained unchanged with norm (34.0% and decreased in het-norm/high women (10.0%; P<0.0001. Pregnancy rates were significantly higher with norm (38.6% than het-norm/low (22.2%, p=0.001. FMR1 sub-genotype het-norm/low is strongly associated with autoimmunity and decreased pregnancy chances in IVF, reaffirming the importance of the distal long arm of the X chromosome (FMR1 maps at Xq27.3 for autoimmunity, ovarian function and, likely, pregnancy chance with IVF.

  16. Application of Chance-Constrained Stochastic Optimization for Mitigating Downstream Flood Risks

    Ensemble forecasting is a growing field in the operation of multi-purpose reservoirs and mitigation of flood risks in downstream river reaches. The assessment of uncertainty over the prediction horizon provides added value to the operational flow forecasting system. It provides probabilistic inflow forecasts which, combined with decision support systems, determine optimum release strategies. One way of doing this is through scenario tree-based stochastic optimization. The representation of the ensemble forecasted is converted into a scenario-tree and optimized based on an adaptive multi-stage stochastic optimization. Typical inequality constraints applied over this problem require a full compliance of each ensemble's trajectory and neglect the uncertainty distribution. We propose the application of chance constrained optimization to overcome such problem, allowing a more flexible approach that does not depend on the number of ensembles but rather on the distribution of uncertainty. This technique is used to compute release trajectories of the reservoirs over a finite forecast horizon of up to 14 days by integrating a nonlinear gradient-based optimization algorithm and a model of the water system. The latter consists of simulation components for pool routing and kinematic or diffusive wave models for the downstream river reaches including a simulation mode and a reverse adjoint mode for the efficient computation of first-order derivatives. This framework has been implemented for a reservoir system operated by the Brazilian Companhia Energética de Minas Gerais S.A. (CEMIG). We present results obtained for the operation of the Tres Marias reservoir in the Brazilian state of Minas Gerais with a catchment area of near 55,000 km2. The focus of our discussion is the impact of chance constrains on the optimization procedure and its flexibility for extending the number of ensemble forecasts thus providing a more accurate representation of uncertainty.

    The introduction of seatbelts to legislation has dramatically reduced mortality and morbidity from motor vehicle accidents. However, overtime evidence has emerged of 'seatbelt syndrome' (SBS), particularly in the paediatric population. The report describes the diagnosis and management of this rare injury in a 12-year-old boy who sustained a chance lumbar fracture and mesenteric tear resulting in small bowel obstruction. His stay was subsequently complicated by superior mesenteric artery (SMA) syndrome. This is the first documented case of SBS with SMA syndrome. High index of suspicion and continuity of care, particularly in the setting of a 'seatbelt sign', is paramount to timely diagnosis and management.

    Due to intensive marketing and the rapid growth of online gambling, poker currently enjoys great popularity among large sections of the population. Although poker is legally a game of chance in most countries, some (particularly operators of private poker web sites) argue that it should be regarded as a game of skill or sport because the outcome of the game primarily depends on individual aptitude and skill. The available findings indicate that skill plays a meaningful role; however, serious methodological weaknesses and the absence of reliable information regarding the relative importance of chance and skill considerably limit the validity of extant research. Adopting a quasi-experimental approach, the present study examined the extent to which the influence of poker playing skill was more important than card distribution. Three average players and three experts sat down at a six-player table and played 60 computer-based hands of the poker variant "Texas Hold'em" for money. In each hand, one of the average players and one expert received (a) better-than-average cards (winner's box), (b) average cards (neutral box) and (c) worse-than-average cards (loser's box). The standardized manipulation of the card distribution controlled the factor of chance to determine differences in performance between the average and expert groups. Overall, 150 individuals participated in a "fixed-limit" game variant, and 150 individuals participated in a "no-limit" game variant. ANOVA results showed that experts did not outperform average players in terms of final cash balance. Rather, card distribution was the decisive factor for successful poker playing. However, expert players were better able to minimize losses when confronted with disadvantageous conditions (i.e., worse-than-average cards). No significant differences were observed between the game variants. Furthermore, supplementary analyses confirm differential game-related actions dependent on the card distribution, player status

    The comprehension section of the Nelson-Denny Reading Test (NDRT) is widely used to assess the reading comprehension skills of adolescents and adults in the United States. In this study, the authors explored the content validity of the NDRT Comprehension Test (Forms G and H) by asking university students (with and without at-risk status for learning disorders) to answer the multiple-choice comprehension questions without reading the passages. Overall accuracy rates were well above chance for both NDRT forms and both groups of students. These results raise serious questions about the validity of the NDRT and its use in the identification of reading disabilities.

  3. [Negotiating safer sex].

    Gordon, G; Charnock, D

    1991-01-01

    Women have generally assumed responsibility for contraception since the appearance of oral contraceptives and IUDs. But AIDS prevention programs are now asking women to assume responsibility for safer sex through use of condoms, a male method. Women are being asked to carry condoms, to negotiate their use each time they have sex, and to insist if the partner resists. The problem with this strategy is that frequently it is the male partner who makes sexual decisions, and women have less negotiating power. Women are considered feminine if they assume a passive role in sexual activity. This work suggests strategies to improve the negotiating power of women. Options and problems of speaking about safer sex vary in accordance with the nature of the relationship. A woman with a new partner can try to ascertain his sexual history, but may gain no information on his probable health even if he tells her the truth. It may be easier to convince him to use a condom at least in the beginning of the romance. Women working in the sex industry often have greater trouble convincing their friends and lovers to use a condom than their clients. Some family planning workers have begun to speak of safer sex with all their clients. Role playing and workshops or discussions with small groups of women having similar problems may help women overcome their reticence about discussing sexual topics. Some general suggestions to help women negotiate safer sex include choosing an opportune moment and planning in advance what to say; daring to speak directly without beating around the bush (the partner may also be gathering courage to speak); practicing placing condoms on objects and if necessary placing one on the partner without speaking; being honest with the partner about sex, love, and fidelity; and remembering that protection from condoms is mutual given that it is not possible to know who is infected. Until now, programs to help women practice safer sex have concentrated on sex industry

    The article on sex education in Portugal covers background, the educational system, the clashes of the 1960's over sex education, the Committee for the Study of Sexuality and Education (CSSE), the policies, politics and social movements during the period 1974 - 1984, the discussions in Parliament, the 1988 Reform of the Educational System, the Family Planning Association (FPA) and sex education, and the future role of the FPA. It was not until the institution of the multiparity parliamentary system in 1974 that discussing social and political changes was possible, culminating in 1984 with new legislation on abortion, family planning, and sex education. School reform came in 1987/8 with the Ministry of Education primarily responsible for curricula. The 1960's brought with it the influence of the Catholic Church. Change came in the form of progressivism among Catholics who replaced dogma with dialogue and listening. Sex education was considered as preparation for marriage, but masturbation, contraception, and prostitution were also discussed. In addition, the founder of FPA chaired the CSSE in 1971 and opened up debate on sex issues and drafted a bill to establish co-education in Portuguese schools. The revolution of 1974 brought an end to censorship and brought forth a policy of developing family planning. Changed in the Family Code gave women greater equality. UNFPA supported teacher training in non-sexist education. With human reproduction included in the natural sciences, there was still no school sex education policy and contraception was only sometimes represented in the biology curriculum. The focus of FPA was on contraception and abortion. Finally in the 1980's, the first sex education programs were developed for out-of-school youth. Even though in the 1970's there were leftists groups promoting sex education, it took leftist parliamentary power to get legislation on sex education in the schools adopted. The Ministry of Education however was pressured by the

    The Chance fracture occurs frequently in school-aged patients' population and is related to flexion-distraction injury in motor vehicle accidents. It is so called seat-belt syndrome because the seatbelt lies over the abdomen. After sudden deceleration bends the child around the lap belt causing injuries to the abdomen, and the spine (e.g., Chance fracture). The Chance fracture after a low energy fall in elderly patient's population has rarely been reported. We present an 82 years old patient who suffered unrecognized Chance fracture after a low energy fall. The management of this patient with positive sagittal imbalance and previous arthrodesis consisted of decompression, Smith-Petersen osteotomy and posterior pedicle screw instrumentation.

    Chronic use of alcohol is considered to be a potential risk factor for the incidence of type 2 diabetes mellitus (T2DM), which causes insulin resistance and pancreatic β-cell dysfunction that is a prerequisite for the development of diabetes. However, alcohol consumption in diabetes has been controversial and more detailed information on the diabetogenic impact of alcohol seems warranted. Diabetes, especially T2DM, causes dysregulation of various metabolic processes, which includes a defect in the insulin-mediated glucose function of adipocytes, and an impaired insulin action in the liver. In addition, neurobiological profiles of alcoholism are linked to the effects of a disruption of glucose homeostasis and of insulin resistance, which are affected by altered appetite that regulates the peptides and neurotrophic factors. Since conditions, which precede the onset of diabetes that are associated with alcoholism is one of the crucial public problems, researches in efforts to prevent and treat diabetes with alcohol dependence, receives special clinical interest. Therefore, the purpose of this mini-review is to provide the recent progress and current theories in the interplay between alcoholism and diabetes. Further, the purpose of this study also includes summarizing the pathophysiological mechanisms in the neurobiology of alcoholism.

    Acute alcohol intoxication causes cellular changes in the brain that last for hours, while chronic alcohol use induces widespread neuroadaptations in the nervous system that can last a lifetime. Chronic alcohol use and the progression into dependence involve the remodeling of synapses caused by changes in gene expression produced by alcohol. The progression of alcohol use, abuse, and dependence can be divided into stages, which include intoxication, withdrawal, and craving. Each stage is associated with specific changes in gene expression, cellular function, brain circuits, and ultimately behavior. What are the molecular mechanisms underlying the transition from recreational use (acute) to dependence (chronic)? What cellular adaptations result in drug memory retention, leading to the persistence of addictive behaviors, even after prolonged drug abstinence? Research into the neurobiology of alcoholism aims to answer these questions. This chapter will describe the molecular adaptations caused by alcohol use and dependence, and will outline key neurochemical participants in alcoholism at the molecular level, which are also potential targets for therapy.

    Full Text Available Case report of patient who has been an alcoholic for 40 years and, after reducing alcohol intake, developed auditory and visual hallucinations, which caused behavior change. Neurological issues, electrolyte disturbances and other organ dysfunctions were excluded as cause of said change. After intake of haloperidol and risperidone, the patient had regression of symptoms and denied having presented hallucinatory symptoms. The Manual Diagnóstico e Estatístico de Transtornos Mentais – 5ª edição (DSM-V includes alcoholic hallucinosis in the Substance-Induced Psychotic Disorder (alcohol, beginning during abstinence; however, the document is not yet very well accepted among the medical community. The difficulty of the team to confirm the diagnosis of alcoholic hallucinosis lies in the differential diagnosis, as Delirium tremens and severe withdrawal syndrome with psychotic symptoms. Thus, psychopathological differentiation is important, as well as continuity of research and collaboration of other clinical teams in the evaluation.

    Chronic alcohol consumption can induce alterations in the function and morphology of most if not all brain systems and structures. However, the exact mechanism of brain damage in alcoholics remains unknown. Partial recovery of brain function with abstinence suggests that a proportion of the deficits must be functional in origin (i.e. plastic changes of nerve cells) while neuronal loss from selected brain regions indicates permanent and irreversible damage. There is growing evidence that chronic alcoholism is associated with a derangement in the sulfur amino acid metabolism. Recently, it has been shown that excitatory amino acid (EAA) neurotransmitters and homocysteine levels are elevated in patients who underwent withdrawal from alcohol. Furthermore, it has been found that homocysteine induces neuronal cell damage by stimulating NMDA receptors as well as by producing free radicals. Homocysteine neurotoxicity via overstimulation of N-methyl-D-aspartate receptors may contribute to the pathogenesis of both brain shrinkage and withdrawal seizures linked to alcoholism.

    Sexual offending by juveniles accounts for a sizable percentage of sexual offenses, especially against young children. In this article, recent research on female juvenile sex offenders (JSOs), risk factors for offending in juveniles, treatment, and the ways in which these youth may differ from general delinquents will be reviewed. Most JSOs do not go on to develop paraphilic disorders or to commit sex offenses during adulthood, and as a group, they are more similar to nonsexual offending juvenile delinquents than to adult sex offenders. Recent research has elucidated some differences between youth who commit sex offenses and general delinquents in the areas of atypical sexual interests, the use of pornography, and early sexual victimization during childhood.

    ABSTRACT OBJECTIVE To describe the patterns of alcohol consumption in Brazilian adolescents. METHODS We investigated adolescents who participated in the Study of Cardiovascular Risks in Adolescents (ERICA). This is a cross-sectional, national and school-based study, which surveyed adolescents of 1,247 schools from 124 Brazilian municipalities. Participants answered a self-administered questionnaire with a section on alcoholic beverages consumption. Measures of relative frequency (prevalence), and their 95% confidence intervals, were estimated for the following variables: use of alcohol beverages in the last 30 days, frequency of use, number of glasses or doses consumed in the period, age of the first use of alcohol, and most consumed type of drink. Data were estimated for country and macro-region, sex, and age group. The module survey of the Stata program was used for data analysis of complex sample. RESULTS We evaluated 74,589 adolescents, who accounted for 72.9% of eligible students. About 1/5 of adolescents consumed alcohol at least once in the last 30 days and about 2/3 in one or two occasions during this period. Among the adolescents who consumed alcoholic beverages, 24.1% drank it for the first time before being 12 years old, and the most common type of alcoholic beverages consumed by them were drinks based on vodka, rum or tequila, and beer. CONCLUSIONS There is a high prevalence of alcohol consumption among adolescents, as well as their early onset of alcohol use. We also identified a possible change in the preferred type of alcoholic beverages compared with previous research. PMID:26910550

    Full Text Available In Botswana, an estimated 24% of adults ages 15-49 years are infected with HIV. While alcohol use is strongly associated with HIV infection in Africa, few population-based studies have characterized the association of alcohol use with specific high-risk sexual behaviors.We conducted a cross-sectional, population-based study of 1,268 adults from five districts in Botswana using a stratified two-stage probability sample design. Multivariate logistic regression was used to assess correlates of heavy alcohol consumption (>14 drinks/week for women, and >21 drinks/week for men as a dependent variable. We also assessed gender-specific associations between alcohol use as a primary independent variable (categorized as none, moderate, problem and heavy drinking and several risky sex outcomes including: (a having unprotected sex with a nonmonogamous partner; (b having multiple sexual partners; and (c paying for or selling sex in exchange for money or other resources. Criteria for heavy drinking were met by 31% of men and 17% of women. Adjusted correlates of heavy alcohol use included male gender, intergenerational relationships (age gap > or =10 y, higher education, and living with a sexual partner. Among men, heavy alcohol use was associated with higher odds of all risky sex outcomes examined, including unprotected sex (AOR = 3.48; 95% confidence interval [CI], 1.65 to 7.32, multiple partners (AOR = 3.08; 95% CI, 1.95 to 4.87, and paying for sex (AOR = 3.65; 95% CI, 2.58 to 12.37. Similarly, among women, heavy alcohol consumption was associated with higher odds of unprotected sex (AOR = 3.28; 95% CI, 1.71 to 6.28, multiple partners (AOR = 3.05; 95% CI, 1.83 to 5.07, and selling sex (AOR = 8.50; 95% CI, 3.41 to 21.18. A dose-response relationship was seen between alcohol use and risky sexual behaviors, with moderate drinkers at lower risk than both problem and heavy drinkers.Alcohol use is associated with multiple risks for HIV transmission among both men

    In his famous Essay towards solving a problem in the doctrine of chances, Bayes calculates probabilities as chances to be in the right in one's guess or as fractions of certainty. He was led to use two schemas. The first one is a monetary schema. But he forwarded a second schema of a square table on which a ball is thrown and the points where it rests are located and recorded. This schema was to him the best possible one to give shape to the problem of ascertaining the degree of trust to be given to a guess when, having at one's disposal only a small number of data about the conjunction of subsequent events, one extrapolates from this small number to a greater number. The purpose of my paper is to examine the nature of the "I" of the "I guess", which must be understood in a transcendental or intersubjective way rather than in a private or individual sense. But then, the right interpretation of the Bayesian "I guess" might well be found in terms of the theory of games, as convincingly expounded by J. C. Harsanyi.

    2008-01-01

    When calculating IMFs for young clusters, one has to take into account that (a) most massive stars are born in multiple systems (b) most IMFs are derived from data that cannot resolve such systems, and (c) multiple chance superpositions between members are expected to happen if the cluster is too distant. In this article I use numerical experiments to model the consequences of those phenomena on the observed color-magnitude diagrams and the IMFs derived from them. Real multiple systems affect the observed or apparent massive-star MF slope little but can create a significant population of apparently ultramassive stars. Chance superpositions produce only small biases when the number of superimposed stars is low but, once a certain number threshold is reached, they can affect both the observed slope and the apparent stellar upper mass limit. I apply those experiments to two well known massive young clusters in the Local Group, NGC 3603 and R136. In both cases I show that the observed population of stars with mas...

  13. The Long-term Survival Chances of Young Massive Star Clusters

    Richard de Grijs; Geneviève Parmentier

    2007-01-01

    We review the long-term survival chances of young massive star clusters (YMCs),hallmarks of intense starburst episodes often associated with violent galaxy interactions. We address the key question as to whether at least some of these YMCs can be considered protoglobular clusters (GCs), in which case these would be expected to evolve into counterparts of the ubiquitous old GCs believed to be among the oldest galactic building blocks. In the absence of significant external perturbations, the key factor determining a cluster's long-term survival chances is the shape of its stellar initial mass function (IMF). It is, however, not straightforward to assess the IMF shape in unresolved extragalactic YMCs. We discuss in detail the promise of using high-resolution spectroscopy to make progress towards this goal,as well as the numerous pitfalls associated with this approach. We also discuss the latest progress in worldwide efforts to better understand the evolution of entire cluster systems, the disruption processes they are affected by, and whether we can use recently gained insights to determine the nature of at least some of the YMCs observed in extragalactic starbursts as proto-GCs. We conclude that there is an increasing body of evidence that GC formation appears to be continuing until today; their long-term evolution crucially depends on their environmental conditions, however.

    Critical environmental and human health concerns are associated with the rapidly growing fields of nanotechnology and manufactured nanomaterials (MNMs). The main risk arises from occupational exposure via chronic inhalation of nanoparticles. This research presents a chance-constrained nonlinear programming (CCNLP) optimization approach, which is developed to maximize the nanaomaterial production and minimize the risks of workplace exposure to MNMs. The CCNLP method integrates nonlinear programming (NLP) and chance-constrained programming (CCP), and handles uncertainties associated with both the nanomaterial production and workplace exposure control. The CCNLP method was examined through a single-walled carbon nanotube (SWNT) manufacturing process. The study results provide optimal production strategies and alternatives. It reveal that a high control measure guarantees that environmental health and safety (EHS) standards regulations are met, while a lower control level leads to increased risk of violating EHS regulations. The CCNLP optimization approach is a decision support tool for the optimization of the increasing MNMS manufacturing with workplace safety constraints under uncertainties.

    Full Text Available As a type of renewable energy, wind energy is integrated into the power system with more and more penetration levels. It is challenging for the power system operators (PSOs to cope with the uncertainty and variation of the wind power and its forecasts. A chance-constrained economic dispatch (ED model for the wind-thermal-energy storage system (WTESS is developed in this paper. An optimization model with the wind power and the energy storage system (ESS is first established with the consideration of both the economic benefits of the system and less wind curtailments. The original wind power generation is processed by the ESS to obtain the final wind power output generation (FWPG. A Gaussian mixture model (GMM distribution is adopted to characterize the probabilistic and cumulative distribution functions with an analytical expression. Then, a chance-constrained ED model integrated by the wind-energy storage system (W-ESS is developed by considering both the overestimation costs and the underestimation costs of the system and solved by the sequential linear programming method. Numerical simulation results using the wind power data in four wind farms are performed on the developed ED model with the IEEE 30-bus system. It is verified that the developed ED model is effective to integrate the uncertain and variable wind power. The GMM distribution could accurately fit the actual distribution of the final wind power output, and the ESS could help effectively decrease the operation costs.

  17. Can Characteristics of Reciprocal Translocations Predict the Chance of Transferable Embryos in PGD Cycles?

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Translocation carriers have an increased risk of miscarriage or the birth of a child with congenital anomalies. Preimplantation genetic diagnosis (PGD is performed in translocation carriers to select for balanced embryos and, thus, increase the chance of an ongoing pregnancy. However, a common experience is that reciprocal translocation carriers produce a high percentage of unbalanced embryos, which cannot be transferred. Therefore, the pregnancy rates in PGD in this patient group are low. In a cohort of 85 reciprocal translocation carriers undergoing PGD we have searched for cytogenetic characteristics of the translocations that can predict the percentage of balanced embryos. Using shape algorithms, the most likely segregation mode per translocation was determined. Shape algorithm, breakpoint location, and relative chromosome segment sizes proved not to be independent predictors of the percentage of balanced embryos. The ratio of the relative sizes of the translocated segments of both translocation chromosomes can give some insight into the chance of transferable embryos: Very asymmetrical translocations have a higher risk of unbalanced products (p = 0.048. Counseling of the couples on the pros and cons of all their reproductive options remains very important.

    Forty years after the publication of Beyond Freedom and Dignity (Skinner, 1971) and the continuing growth of behavior analysis, the future of humanity and the role of behavioral science in that future remain uncertain. A recent paper by Chance (2007) documented a shift in Skinner's views during the last years of his life. Skinner had long advocated a science and technology of behavior for finding and engineering solutions to cultural and global problems and advancing human development. This optimism had given way under a gradual realization that the science of behavior was in fact showing how such problems were unlikely to be solved in time to avert a variety of possible disasters. Chance described nine behavioral phenomena that appear to interfere with effective problem-solving behavior on a large scale and in effective time frames. These phenomena are reviewed toward an analysis of common themes. Research is also reviewed that involves nonverbal, verbal, and cultural contingencies that may lead to applications designed to address the common themes. Problems and strategies of implementation are also discussed. The challenges are daunting, but may nevertheless be regarded as technical problems best suited for a science and technology of behavior.

    This paper presents a novel stochastic level set method for the longitudinal tracking of lung tumors in computed tomography (CT). The proposed model addresses the limitations of registration based and segmentation based methods for longitudinal tumor tracking. It combines the advantages of each approach using a new probabilistic framework, namely Chance-Constrained Programming (CCP). Lung tumors can shrink or grow over time, which can be reflected in large changes of shape, appearance and volume in CT images. Traditional level set methods with a priori knowledge about shape are not suitable since the tumors are undergoing random and large changes in shape. Our CCP level set model allows to introduce a flexible prior to track structures with a highly variable shape by permitting a constraint violation of the prior up to a specified probability level. The chance constraints are computed from two given points by the user or from segmented tumors from a reference image. The reference image can be one of the images studied or an external template. We present a numerical scheme to approximate the solution of the proposed model and apply it to track lung tumors in CT. Finally, we compare our approach with a Bayesian level set. The CCP level set model gives the best results: it is more coherent with the manual segmentation.

    Urinary incontinence (UI) and erectile dysfunction (ED) after radical prostatectomy (RP) can impose a strong burden. While most studies focus on certain time points after RP when analyzing functional outcome, there is paucity of evidence on late functional recovery in patients with UI or ED at 12 mo after RP. Using longitudinal patient data from a large European single-center, we show that the chance of regaining continence among patients (n=974) with UI (≥1 pad/24h) at 12 mo after RP was 38.6% after 24 mo and 49.7% after 36 mo. The corresponding rates for patients (n=1115) with ED (defined as International Index of Erectile Function-5 score <18) at 12 mo after RP were 30.8% at 24 mo and 36.5% at 36 mo after RP. Patients with postoperative UI or ED 12 mo after RP should be counseled about their good chance of achieving continence or potency in the course of time. We analyzed the probability of functional recovery among patients with urinary incontinence (UI) and erectile dysfunction (ED) 12 mo after radical prostatectomy. We found that up to 49.7% (36.5%) of patients with UI (ED) regain function within the next 24 mo and should be informed about these encouraging numbers.
