Many of these pregnancies are unwanted and these mothers are also exposed to the risk of human immunodeficiency virus (HIV infection. Sexual abstinence is a critical preventative health strategy. Several quantitative studies in Nigeria have identified the correlates and determinants of early sex, yet few have explored in depth the underlying reasons for early sex. This paper explores both the key factors that motivate some unmarried young people to engage in early sex and reasons why some delay.Methods: This qualitative study was based on data from 30 focus group discussions held with unmarried 14- to 19-year-olds in four geographically and culturally dispersed Nigerian states. Focus groups were stratified by sexual experience to capture variations among different subgroups.Results: Several reasons for early premarital sex were identified. The “push” factors included situations where parents exposed young female adolescents to street trading. “Pull” factors, particularly for males, included the pervasive viewing of locally produced movies, peer pressure and, for females, transactional sex (where adolescent girls exchange sex for gifts, cash, or other favors. Also noted were overtly coercive factors, including rape. There were also myths and misconceptions that “justified” early sexual initiation. Reasons cited for delay included religious injunction against premarital sex; disease prevention (especially HIV/acquired immunodeficiency syndrome; fear of pregnancy, and linked to this, the fear of dropping out of school; and, for females, the fear of bringing shame to the family, which could lead to their inability to get a "good" husband in the future.Conclusion: The differences

    Reducing new HIV/STD infections among at-risk adolescents requires developing and evaluating evidence-based health communication approaches. Research overwhelmingly supports the conclusion that early sexual initiation is associated with STDs and other negative outcomes in later years (e.g., unintended pregnancy). The authors' research group secured funding from the National Institute of Mental Health to develop, implement, and rigorously evaluate televised mass media campaigns to delay initiation of sexual intercourse among African American and White adolescents in two cities in the Southeastern United States. The focus of the present study is on the development and implementation of the campaigns, including (a) rationale and theoretical underpinnings; (b) collection, screening, and assessment of existing public service announcements; (c) development of new public service announcements; (d) study design and campaign airing plan; and (e) message exposure achieved in the campaigns. Health communication campaigns hold much promise in reaching at-risk adolescent populations with targeted, timely, and relevant risk-reduction messages.

    Full Text Available Pentecostal denominations in Brazil are recognized for their promotion of conservative norms and punitive sanctions related to the sexual behavior of their young members. Moreover, they have created unique space for their followers to actively participate in a religious environment. Using data from the PNDS-2006 (National Survey on the Demography and Health of Children and Women, Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher de 2006, we examine the associations, in Brazil between religion, as measured by religious affiliation and attendance at religious services, and premarital adolescent sexual initiation. Our main results confirm a strong association between delay in sexual initiation and Pentecostalism in Brazil and suggest that this association be related to frequent attendance at religious services. These findings are intriguing, especially because Pentecostalism has emerged and concentrated among socioeconomically disadvantaged populations, including the least-educated women, with lower income, and residents of urban areas. We conclude by suggesting that religion may be taking the place of family and school in communication on adolescent sexual behavior in Brazil. This hypothesis should be carefully investigated, since the religious teachings may sometimes be in favor of what families and the state see as beneficial for adolescents and youth in general, but sometimes in disaccord.

    A robust link between early sexual initiation and sexual risk-taking behavior is reported in previous studies. The relationship may not be causal, however, as the effect of common risk factors is often not considered. The current study examined whether early initiation was a key predictor of risky sexual behavior in the 20s and 30s, over and above co-occurring individual and environmental factors. Data were drawn from the Seattle Social Development Project, a longitudinal panel of 808 youth. Early predictors (ages 10 to 15) and sexual risk taking (ages 21 to 24 and 30 to 33) were assessed prospectively. Early sexual initiation (before age 15) was entered into a series of probit regressions that also included family, neighborhood, peer, and individual risk factors. Although a positive bivariate relation between early sexual initiation and sexual risk taking was observed at both ages, the link did not persist when co-occurring risk factors were included. Behavioral disinhibition and antisocial peer influences emerged as the strongest predictors of sexual risk over and above early sexual initiation. These results suggest that early sexual initiation must be considered in the context of common antecedents; public health policy aimed at delaying sexual intercourse alone is unlikely to substantially reduce sexual risk behavior in young adulthood.

    This study aimed to assess initial symptoms and factors associated with patients' and doctors' delay in penile carcinoma. Fifty consecutive patients with penile carcinoma treated with an organ-sparing technique and nine with partial amputation were enrolled in a prospective study at the Department of Urology, Örebro University Hospital, between 2005 and 2009. Face-to-face structured interviews in combination with self-assessment forms were used for the patients' descriptions of clinical symptoms, treatment seeking and reasons for delay. Data were also extracted from the medical records confirming time-lag between GP assessment, specialist care and time for diagnosis. Erythema, rash and eczema were the most common initial symptoms (35%). In total, 65% had a patients' delay of more than 6 months, and among these there was a small, but not statistically significant, predominance for pT1 and pTis tumours. Living with a stable partner did not affect the delay. The most common reason for patients' delay was the feeling of embarrassment over symptoms localized in a sexual body area. Nine patients had a doctors' delay of more than 3 months from first special visit to diagnosis. Eight of these patients consulted dermatologists and were subjected to repeated biopsies, leaving premalignant results. A considerable proportion of the patients had a patients' delay of more than 6 months, perhaps due to benign initial symptoms as erythema, rash or eczema. Psychological factors such as embarrassment and denial may also be involved, as well as insufficient awareness or knowledge.

  12. Regret Expression and Social Learning Increases Delay to Sexual Gratification.

    Full Text Available Modification and prevention of risky sexual behavior is important to individuals' health and public health policy. This study employed a novel sexual discounting task to elucidate the effects of social learning and regret expression on delay to sexual gratification in a behavioral task.Amazon Mechanical Turk Workers were assigned to hear one of three scenarios about a friend who engages in similar sexual behavior. The scenarios included a positive health consequence, a negative health consequence or a negative health consequence with the expression of regret. After reading one scenario, participants were asked to select from 60 images, those with whom they would have casual sex. Of the selected images, participants chose one image each for the person they most and least want to have sex with and person most and least likely to have a sexually transmitted infection. They then answered questions about engaging in unprotected sex now or waiting some delay for condom-protected sex in each partner condition.Results indicate that the negative health outcome scenario with regret expression resulted in delayed sexual gratification in the most attractive and least STI partner conditions, whereas in the least attractive and most STI partner conditions the negative health outcome with and without regret resulted in delayed sexual gratification.Results suggest that the sexual discounting task is a relevant laboratory measure and the framing of information to include regret expression may be relevant for prevention of risky sexual behavior.

    The purpose of this secondary analysis of data is to examine relationships among Asian American Pacific Islanders (AAPI) adolescents' level of acculturation, maternal influences, and age of sexual initiation. Selected predictive variables are based on the theoretical frameworks and literature review. The results indicate that for these adolescents speaking English at home was positively associated with maternal sexual discussion, mothers' perceptions of connectedness with their adolescents, adolescents' perceived maternal sexual expectations, and later sexual initiation at Wave 1. Adolescents' years of U.S. residency are positively associated with adolescents' level of perceived connectedness with their mothers and later sexual initiation at Wave 2. Adolescents' level of acculturation influence how they interacted with their mothers, perceived their mothers' sexual expectations, and when they decided to initiate sexual intercourse. Interventions to delay AAPI adolescents' sexual debut should consider factors related to AAPI adolescents' and their mothers' levels of acculturation.

  15. Does the Organized Sexual Murderer Better Delay and Avoid Detection?

    Beauregard, Eric; Martineau, Melissa

    2016-01-01

    According to the organized-disorganized model, organized sexual murderers adopt specific behaviors during the commission of their crimes that contribute to avoiding police detection. The current study examines the effect of sexual murderers' organized behaviors on their ability to both delay and/or avoid police detection. Using a combination of negative binomial and logistic regression analyses on a sample of 350 sexual murder cases, findings showed that although both measures of delaying and avoiding detection are positively correlated, different behavioral patterns were observed. For instance, offenders who moved the victim's body were more likely to avoid detection but the victim's body was likely to be recovered faster. Moreover, victim characteristics have an impact on both measures; however, this effect disappears for the measure of delaying detection once the organized behaviors are introduced. Implications of the findings are discussed.

    Sexual initiation during adolescence has important demographic and health consequences for a population, yet no systematic analysis of changes in the timing of sexual initiation has been conducted in Nigeria. Two rounds of national surveys conducted in 1990 and 2003 were used to examine changes in the timing of sexual initiation among female adolescents in Nigeria. Multivariate survival analysis using Cox proportional hazards models was used to assess changes in the risk of sexual initiation and to identify the correlates of first sex. Contrary to what has been reported in several Nigerian studies, there was no decline in age at first sex among Christian adolescents. Age at first sex did not change significantly for Christian adolescents, although premarital sex appears to have increased-primarily due to an increase in the age at marriage. Age at first sex did increase among Muslim women. Premarital sex remained low among Muslim women. A number of socioeconomic variables were associated with the timing of sexual initiation. Weekly exposure to the mass media was associated with earlier sexual initiation. The degree to which an environment was liberal or restrictive was a key determinant of the timing of sexual initiation in Nigeria. The findings also illustrate the important role of socioeconomic factors in determining the timing of sexual initiation in Nigeria. As secondary education increases in Northern Nigeria, additional increases in the age at sexual debut are likely among Muslim women. The study raises concerns about the influence of the mass media on the timing of first sex in Nigeria. The evidence of an absence of changes in the timing of sexual initiation among Christian women in more than a decade implies that programs which aim to delay the timing of sexual initiation in Southern Nigeria may have limited success. With age at marriage already high among Christian women, programs that focus on abstinence until marriage may also be pursuing an approach with

    Full Text Available Abstract Background To explore any association between the timing of the initiation of sexual activity and sexual behaviors and risks among university students in China. Methods Data were derived from a cross-sectional study on sexual behavior among university students conducted in Ningbo municipality, China, at the end of 2003. Students completed a self-administered, structured questionnaire. Of 1981 sexually active male students, 1908 (96.3% completed the item for timing of the initiation of sexual activity and were included in bivariate trend analyses and multiple logistic regression analyses to compare the association between this timing and sexual behavior and risks. Results Male early sexual initiators had a significantly higher risk profile, including a significantly higher proportion reporting non-regular partners (i.e., casual or commercial partners, multiple partners, diagnosis with a sexually transmitted disease (STD, partner history of pregnancy, partner history of induced abortion, and less condom and oral contraceptive use, compared with late initiators. Multivariate analyses confirmed the increased likelihood of these risks in early initiators versus late initiators, other than partner type during the last year. Conclusion Our results showed that, compared to late initiators, people who initiated sexual activity early engaged in more risky behaviors that could lead to elevated risks of unwanted pregnancies and STDs or human immunodeficiency virus infection. Sex-education strategies should be focused on an earlier age, should include advice on delaying the age of first sexual activity, and should target young people who continue to take sexual risks.

    2015-03-01

    This study aims to explore the association between early sex initiation and subsequent unsafe sexual behaviors and risks among Chinese female undergraduates. Of 4769 participants, 863 (18.1%) reported ever having sexual intercourse. The mean age of sexual debut was 19.3 (±1.7) years. Females initiating sex earlier were more likely to have first sex with men who were not their "boyfriends" and less likely to take contraception, to use a condom at first encounter, to use contraception consistently in past year, and/or to use condom consistently during the course of a sexual intercourse. They were more likely to have multiple lifetime and concurrent sexual partners, to report pregnancy, and be diagnosed with sexually transmitted diseases. Comprehensive early sex education should be advocated for young people, not only teaching knowledge of physical health but also providing practical skills training for making them consciously delay start of sexual activity or protecting themselves during sexual intercourse.

    2015-05-01

    Infantile-onset saccade initiation delay, also known as congenital ocular motor apraxia, typically presents in early infancy with horizontal head thrusts once head control is achieved. Defective initiation of horizontal saccades and saccade hypometria with normal saccadic velocity are characteristic findings. Isolated impairment of vertical saccades is rare. Impaired smooth ocular pursuit may be seen. Other relatively common features include developmental delay, hypotonia, ataxia, or clumsiness. Brain MRI may be normal or show a diverse range of abnormalities, most commonly involving the cerebellum. Defective slow phases of the optokinetic response are commonly associated with brain MRI abnormalities. Isolated defect of vertical saccade initiation may indicate supratentorial brain abnormalities on MRI. Joubert syndrome, a developmental midbrain-hindbrain malformation, and ataxia telangiectasia are both commonly associated with defective volitional and reflexive saccade initiation, saccade hypometria, and head thrusts. Both horizontal and vertical saccades are impaired in these two disorders.

    Simultaneous measurements of high altitude optical emissions and the magnetic field produced by sprite-associated lightning discharges enable a close examination of the link between low altitude lightning process and high altitude sprite process. In this work, we report results of the coordinated analysis of high speed (1000--10000 frames per second) sprite video and wideband (0.1 Hz to 30 kHz) magnetic field measurements made simultaneously at the Yucca Ridge Field Station and Duke University during the June through August 2005 campaign period. During the observation period, the high speed camera detected 83 sprite events in 67 TLE sequences, which are caused by the same number of +CGs. 46% of these sprite events are delayed more than 10 ms after the lightning return stroke. With the estimated lightning source current moment waveform, we computed the continuing current amplitude and total charge transfer characteristics of the long delayed sprites (>10 ms delay). Our calculation shows the total charge moment change of the long delayed sprites can vary from several hundred C km to more than ten thousand C km. All the long delayed sprites are related with intense continuing current bigger than 2 kA. This continuing current provides about 50% to 90% of the total charge transfer. However, a bigger continuing current does not necessarily mean a shorter time delay. This indicates that other processes also involved in the sprite initiation for long delayed sprites. In our observations, the sferic burst, a high frequency noise caused by intra-cloud activity, is always accompanied by a slow intensification in the lightning source current before the time of sprite initiation. Thus we used the lightning source current as an input and employed a 2-D FDTD model to numerically simulate the electric field at different altitudes and compare it with the breakdown field. Including the effect of the electron mobility dependence on electric field, the simulation results showed that

    2015-09-01

    Numerous studies have documented the determinants of sexual behavior among adolescents in less-developed countries, yet relatively little is known about the influence of social contexts such as school and neighborhood. Using two waves of data from a school-based longitudinal survey conducted in Malawi from 2011-13, this study advances our understanding of the relationship between school-level socioeconomic contexts and adolescents' sexual activity. The results from two-level multinomial logistic regression models suggest that high socioeconomic composition of the student body in school decreases the odds of initiation of sexual activity, independent of other important features of schools and individual-level characteristics. This study also finds that the association between school socioeconomic composition and sexual activity is statistically significant among male adolescents but not female adolescents, suggesting that schools' socioeconomic contexts may be more relevant to male adolescents' initiation of sexual activity.

    Sexually transmissible infections (STIs) are responsible for a significant burden of disease in both developed and developing countries and young people are disproportionately affected by STIs and their consequences. STI rates in young people are determined by a wide range of well documented influences. These include physiological, cognitive and behavioural factors, as well as environmental factors such as the social, and cultural context in which young people live. Despite the erecognition of these influences, their complex inter-relationships are less well documented and the evidence for interventions to reduce STIs in young people is similarly less clear. This paper explore tht most important factors that impact STI rates in young people in Australia and reviews interventions that have shown success, in Australia and elsewhere. In addition, promising strategies for the promotion of sexual health and reduction of STIs in young Australians, are discussed.

    Few studies have examined the health and developmental consequences, including unintended pregnancy, of different sexual behavior initiation sequences. Some work suggests that engaging in oral-genital sex first may slow the transition to coital activity and lead to more consistent contraception among adolescents. Using logistic regression analysis, we investigated the association between sequences of sexual initiation (i.e., initiating oral-genital or vaginal sex first based on reported age of first experience) and the likelihood of subsequent teenage pregnancy among 6,069 female respondents who reported vaginal sex before age 20 years and participated in waves I and IV of the National Longitudinal Study of Adolescent Health. Among female respondents initiating vaginal sex first, 31.4% reported a teen pregnancy. Among female respondents initiating two behaviors at the same age, 20.5% reported a teen pregnancy. Among female respondents initiating oral-genital sex first, 7.9% reported a teen pregnancy. In multivariate models, initiating oral-genital sex first, with a delay of at least 1 year to vaginal sex, and initiating two behaviors within the same year were each associated with a lower likelihood of adolescent pregnancy relative to teens who initiated vaginal sex first (odds ratio = .23, 95% confidence interval: .15-.37; and odds ratio = .78, 95% confidence interval: .60-.92, respectively). How adolescents begin their sexual lives may be differentially related to positive and negative health outcomes. To develop effective pregnancy prevention efforts for teens and ensure programs are relevant to youths' needs, it is important to consider multiple facets of sexual initiation and their implications for adolescent sexual health and fertility.

    A robust link between early sexual initiation and sexual risk-taking behavior is reported in previous studies. The relationship may not be causal, however, as the effect of common risk factors is often not considered. The current study examined whether early initiation is a key predictor of risky sexual behavior in the 20s and 30s, over and above co-occurring individual and environmental factors. Data were drawn from the Seattle Social Development Project, a longitudinal panel of 808 youth. E...

    Coerced or forced sexual initiation and sexual intimate partner violence (sexual IPV) contribute significantly to a woman's risk for HIV infection. This review systematically examines global research (n = 21 studies) published since 2000 on the role of coerced/forced sexual initiation and sexual IPV on HIV risk in women. In predominantly low- and middle-income countries, coerced/forced sexual initiation was associated with HIV/STIs, multiple and high-risk sex partners, and no condom use. Most studies using behaviorally specific terms for sexual IPV found strong associations between sexual IPV and HIV risk behaviors. In contrast, studies using less specific definitions often failed to find these significant associations. To develop more comprehensive HIV prevention programs, future efforts should integrate behaviorally specific terms into assessing prevalence of sexual IPV and its association with HIV risk, consider cultural differences, and identify causal pathways between coerced or forced sexual initiation, HIV risk behaviors and HIV/STI infection.

    Purpose To examine the relationship between country-level age norms for sexual initiation timing and early sexual initiation (ESI) among adolescent boys and girls. Methods Nationally-representative data from 17 countries that participated in the 2006/07 European Social Survey (ESS-3, n=33,092) and the 2005/06 Health Behaviour in School-Aged Children Study (HBSC, n=27,702) were analyzed. Age norms were measured as the average country-level response to an item asking the age at which ESS respondents believed someone is too young to have sexual intercourse. HBSC respondents (aged 14-16) self-reported age at sexual initiation which we defined as early (<15 years) or not (≥15 years or no initiation). Control variables included age, family affluence, perceived socioeconomic status, family living arrangement, substance use, school attachment, and country-level legal age of consent. Multivariable three-level logistic models with random intercepts were run separately by sex. Results In multivariable analyses, higher overall age norms were associated with reduced likelihood of ESI among girls (AOR 0.60, 95% CI 0.45-0.79); associations with ESI were stronger for parent cohort (ages 31-65) norms (AOR 0.37, 95% CI 0.23-0.58) than for peer cohort (ages 15-20) norms (AOR 0.60, 95% CI 0.49-0.74). For boys, overall norms were also significantly negatively associated with ESI (AOR 0.68, 95% CI 0.46-0.99), as were parent cohort norms (AOR 0.66, 95% CI 0.45-0.96). Peer cohort norms were not significantly related to boys’ ESI. Conclusion Macro-level cultural norms may impact adolescents’ sexual initiation timing. Research exploring the sexual health outcomes of early initiators in countries with contrasting age norms is warranted. PMID:24508092

    Several behavioral studies have shown that the reaction times of visually guided movements are slower in people with amblyopia, particularly during amblyopic eye viewing. Here, we tested the hypothesis that the initiation of smooth pursuit eye movements, which are responsible for accurately keeping moving objects on the fovea, is delayed in people with anisometropic amblyopia. Eleven participants with anisometropic amblyopia and 14 visually normal observers were asked to track a step-ramp target moving at ±15°/s horizontally as quickly and as accurately as possible. The experiment was conducted under three viewing conditions: amblyopic/nondominant eye, binocular, and fellow/dominant eye viewing. Outcome measures were smooth pursuit latency, open-loop gain, steady state gain, and catch-up saccade frequency. Participants with anisometropic amblyopia initiated smooth pursuit significantly slower during amblyopic eye viewing (206 ± 20 ms) than visually normal observers viewing with their nondominant eye (183 ± 17 ms, P = 0.002). However, mean pursuit latency in the anisometropic amblyopia group during binocular and monocular fellow eye viewing was comparable to the visually normal group. Mean open-loop gain, steady state gain, and catch-up saccade frequency were similar between the two groups, but participants with anisometropic amblyopia exhibited more variable steady state gain (P = 0.045). This study provides evidence of temporally delayed smooth pursuit initiation in anisometropic amblyopia. After initiation, the smooth pursuit velocity profile in anisometropic amblyopia participants is similar to visually normal controls. This finding differs from what has been observed previously in participants with strabismic amblyopia who exhibit reduced smooth pursuit velocity gains with more catch-up saccades.

    The hypothalamic neuropeptide orexin mediates arousal, sleep, and naturally rewarding behaviors, including food intake. Male sexual behavior is altered by orexin receptor-1 agonists or antagonists, suggesting a role for orexin-A in this naturally rewarding behavior. However, the specific role of endogenous orexin-A or B in different elements of male sexual behavior is currently unclear. Therefore, the current studies utilized markers for neural activation and orexin cell-specific lesions to test the hypothesis that orexin is critical for sexual motivation and performance in male rats. First, cFos expression in orexin neurons was demonstrated following presentation of a receptive or non-receptive female without further activation by different elements of mating. Next, the functional role of orexin was tested utilizing orexin-B conjugated saporin, resulting in orexin cell body lesions in the hypothalamus. Lesions were conducted in sexually naive males and subsequent sexual behavior was recorded during four mating trials. Lesion males showed shortened latencies to mount and intromit during the first, but not subsequent mating trials, suggesting lesions facilitated initiation of sexual behavior in sexually naive, but not experienced males. Likewise, lesions did not affect sexual motivation in experienced males, determined by runway tests. Finally, elevated plus maze tests demonstrated reduced anxiety-like behaviors in lesioned males, supporting a role for orexin in anxiety associated with initial exposure to the female in naive animals. Overall, these findings show that orexin is not critical for male sexual performance or motivation, but may play a role in arousal and anxiety related to sexual behavior in naive animals.

    Individuals with cocaine use disorders are disproportionately affected by HIV/AIDS, partly due to higher rates of unprotected sex. Recent research suggests delay discounting of condom use is a factor in sexual HIV risk. Delay discounting is a behavioral economic concept describing how delaying an event reduces that event's value or impact on behavior. Probability discounting is a related concept describing how the uncertainty of an event decreases its impact on behavior. Individuals with cocaine use disorders (n = 23) and matched non-cocaine-using controls (n = 24) were compared in decision-making tasks involving hypothetical outcomes: delay discounting of condom-protected sex (Sexual Delay Discounting Task), delay discounting of money, the effect of sexually transmitted infection (STI) risk on likelihood of condom use (Sexual Probability Discounting Task), and probability discounting of money. The Cocaine group discounted delayed condom-protected sex (i.e., were more likely to have unprotected sex vs. wait for a condom) significantly more than controls in two of four Sexual Delay Discounting Task partner conditions. The Cocaine group also discounted delayed money (i.e., preferred smaller immediate amounts over larger delayed amounts) significantly more than controls. In the Sexual Probability Discounting Task, both groups showed sensitivity to STI risk, however the groups did not differ. The Cocaine group did not consistently discount probabilistic money more or less than controls. Steeper discounting of delayed, but not probabilistic, sexual outcomes may contribute to greater rates of sexual HIV risk among individuals with cocaine use disorders. Probability discounting of sexual outcomes may contribute to risk of unprotected sex in both groups. Correlations showed sexual and monetary results were unrelated, for both delay and probability discounting. The results highlight the importance of studying specific behavioral processes (e.g., delay and probability

    The topic of same-sex sexual initiation has generally remained understudied in the literature on sexual identity formation among sexual minority youth. This article analyzes the narratives of same-sex sexual initiation provided by 76 gay and bisexual Mexican immigrant men who participated in interviews for the Trayectos Study, an ethnographic study of sexuality and HIV risk. These participants were raised in a variety of locations throughout Mexico, where they also realized their same-sex attraction and initiated their sexual lives with men. We argue that Mexican male same-sex sexuality is characterized by three distinct patterns of sexual initiation--one heavily-based on gender roles, one based on homosociality, and one based on object choice--which inform the men's interpretations regarding sexual roles, partner preferences, and sexual behaviors. We analyzed the social factors and forms of cultural/sexual socialization that lead sexual minority youth specifically to each of these three patterns of sexual initiation. Our findings confirm the importance of studying same-sex sexual initiation as a topic in its own right, particularly as a tool to gain a greater understanding of the diversity of same-sex sexual experiences and sexual identities within and among ethnic/cultural groups.

    This study used the Integrative Model as a framework to examine whether religiosity delays onset of coitus among a longitudinal sample of virgins, and investigated the causal pathways of this relationship. In addition, this study examined the behavioral beliefs about the consequences of engaging in sex, which distinguishes between youth who vary in level of religiosity. A further analysis was also conducted to examine whether religiosity offers protective effects in terms of progression toward sexual intercourse on a sexual behavior index. The sexual behavior index assumes a progressive nature of sexual behaviors, and includes the following seven behaviors: kissing, having breasts touched (touching for boys), genital touching, receiving oral sex, vaginal intercourse, giving oral sex, and receiving (or giving) anal sex. Religiosity at baseline was negatively associated with sexual debut one year later. This relationship was mediated through attitudes toward personally engaging in sexual intercourse. Religiosity at baseline was also negatively associated with scores on the sexual behavior index one year later. These results suggest that religiosity offers protective effects for both coital and noncoital sexual behaviors. PMID:20960362

    2011-04-01

    The high rates of youth migration to urban and economic centers, in the context of persistent poverty and devastating HIV/AIDS burden, have raised intricate social policy challenges in developing countries. Using the 2008 Nigeria Demographic and Health Survey data, descriptive statistics, Kaplan-Meier survival curves and discrete-time hazard regression models, this study examines the patterns of internal migration and sexual initiation among never-married Nigerian youth aged 15-24. We find that migrants generally show stronger association than non-migrants, and urban-rural and rural-rural migrants particularly show the strongest independent association with premarital sexual initiation. Other significant covariates are age, religion, ethnic origin, educational attainment, independent living arrangement, formal employment and exposure to the mass media. The findings highlight the direct importance of youth migration in understanding and addressing the challenges of premarital sexual behavior and the need for behavior change policies and programs to be sensitive to the complex contextual nuances across youth groups in one country.

    Full Text Available Introduction: Under current HIV transmission mechanisms operating in Vietnam, women are seen as victims of their male partners. Having multiple sexual partners is one of the well-known risk factors for HIV infection. However, little is known about women's risky sexual behaviour and their vulnerability to HIV in Vietnam. This study aims to explore association between early sexual initiation and the number of lifetime sexual partners in Vietnamese women. Although the Vietnamese culture is socially conservative in this area, identifying women's risky sexual behaviour is important for the protection of women at risk of HIV and other sexually transmitted diseases. Design: A total of 8,791 women, who reported having had sexual intercourse, were included in this analysis of data from the 2011 Multiple Indicator Cluster Survey in Vietnam. Data were collected using two-stage strata sampling, first at the national level and second across six geographical regions (n=8,791. Multivariable logistic regressions describe association between early initiation of a sexual activity and lifetime multiple sexual partners. Results: Early sexual intercourse was significantly associated with having lifetime multiple sexual partners. Women who were aged 19 or younger at first sexual intercourse were over five times more likely to have multiple sexual partners, compared with women whose first sexual intercourse was after marriage; aged 10–14 years (OR=5.9; 95% CI=1.9–18.8 at first intercourse; and aged 15–19 years (OR=5.4; 95% CI=4.0–7.2 at first intercourse. There was significant association with having multiple sexual partners for women of lower household wealth and urban residence, but the association with educational attainment was not strong. Conclusions: The study results call for health and education policies to encourage the postponement of early sexual activity in young Vietnamese women as protection against risky sexual behaviour later in life.

    Despite the effectiveness of agonist maintenance for opioid dependence, individuals can remain on waitlists for months, during which they are at significant risk for morbidity and mortality. Interim dosing, consisting of daily medication without counseling, can reduce these risks. In this pilot study, we examined the initial feasibility of a novel technology-assisted interim buprenorphine treatment for waitlisted opioid-dependent adults. Following buprenorphine induction during Week 1, participants (n=10) visited the clinic at Weeks 2, 4, 6, 8, 10 and 12 to ingest their medication under staff observation, provide a urine specimen and receive their remaining doses via a computerized Med-O-Wheel Secure device. They also received daily monitoring via an Interactive Voice Response (IVR) platform, as well as random call-backs for urinalysis and medication adherence checks. The primary outcome was percent of participants negative for illicit opioids at each 2-week visit, with secondary outcomes of past-month drug use, adherence and acceptability. Participants achieved high levels of illicit opioid abstinence, with 90% abstinent at the Week 2 and 4 visits and 60% at Week 12. Significant reductions were observed in self-reported past-month illicit opioid use (p<.001), opioid withdrawal (p<.001), opioid craving (p<.001) and ASI Drug composite score (p=.008). Finally, adherence with buprenorphine administration (99%), daily IVR calls (97%) and random call-backs (82%) was high. Interim buprenorphine treatment shows promise for reducing patient and societal risks during delays to conventional treatment. A larger-scale, randomized clinical trial is underway to more rigorously examine the efficacy of this treatment approach. PMID:26256469

    2013-01-01

    The current study investigated sexual initiations within the framework of the Theory of Planned Behavior (TPB) (Ajzen, 1991; Ajzen & Madden, 1986). Male and female daters in heterosexual dating relationships completed an online survey that assessed their sexual relationship with their partner and the TPB components (perceptions of social norms, attitudes, perceived behavioral control, and intentions). The TPB was supported for both men and women in that, as predicted, the more an individual perceived that important others would approve of them initiating sexual activities with their partner, the more positive their evaluations were of the outcomes of initiating, and the more confident they were in their ability to initiate, the stronger were their initiation intentions. In turn, stronger sexual initiation intentions were associated with more frequent initiation behaviors. Compared to women, men initiated more frequently, had stronger sexual initiation intentions, and perceived more positive social norms regarding initiation; men and women did not differ in their attitudes toward sexual initiation or in their perceived behavioral control. Both men and women who reported initiating more frequently and perceived their partner as initiating more frequently reported greater sexual satisfaction. These results are discussed in terms of the utility of the TPB for understanding sexual initiations and the role of the traditional sexual script in initiation-related cognitions and behavior.

  10. Membrane–initiated estradiol signaling regulating sexual receptivity

    Full Text Available Estradiol has profound actions on the structure and function of the nervous system. In addition to nuclear actions that directly modulate gene expression, the idea that estradiol can rapidly activate cell signaling by binding to membrane estrogen receptors (mERs has emerged. Even the regulation of sexual receptivity, an action previously thought to be completely regulated by nuclear ERs, has been shown to have a membrane-initiated estradiol signaling (MIES component. This highlighted the question of the nature of mERs. Several candidates have been proposed, ERα, ERβ, ER-X, GPR30 (G protein coupled estrogen receptor; GPER, and a receptor activated by a diphenylacrylamide compound, STX. Although each of these receptors has been shown to be active in specific assays, we present evidence for and against their participation in sexual receptivity by acting in the lordosis-regulating circuit. The initial MIES that activates the circuit is in the arcuate nucleus of the hypothalamus (ARH. Using both activation of μ-opioid receptors (MOR in the medial preoptic nucleus and lordosis behavior, we document that both ERα and the STX receptor participate in the required MIES. ERα and the STX receptor activation of cell signaling are dependent on the transactivation of type 1 metabotropic glutamate receptors (mGluR1a that augment progesterone synthesis in astrocytes and protein kinase C (PKC in ARH neurons. While estradiol-induced sexual receptivity does not depend on neuroprogesterone, proceptive behaviors do. Moreover, the ERα and the STX receptor activation of medial preoptic MORs and augmentation of lordosis were sensitive to mGluR1a blockade. These observations suggest a common mechanism through which mERs are coupled to intracellular signaling cascades, not just in regulating reproduction, but in actions throughout the neuraxis including the cortex, hippocampus, striatum and DRGs.

    We assessed sexual behaviors before and 12-months after ART initiation among 277 Mozambicans attending an HIV clinic. Measured behaviors included the number of sexual partners, condom use, concurrent relationships, disclosure of HIV status, alcohol use, and partners' serostatus. Compared to before ART initiation, increases were seen 12 months after ART in the proportion of participants who were sexually active (48% vs. 64% respondents, P initiation. Although reported correct and consist condom use increased, the number of unprotected sexual relationships remained the same (n = 45). Non-disclosure of HIV-serostatus to sexual partners was the only significant predictor of practicing unprotected sex with partners of HIV-negative or unknown serostatus. Sexual activity among HIV-positive persons on ART increased 12 months after ART initiation. Ongoing secondary transmission prevention programs addressing sexual activity with multiple partners, disclosure to partners and consistent condom use with serodisconcordant partners must be incorporated throughout HIV care programs.

    Research shows that rap music use is associated with risky sexual behavior in ethnic minority youth; however, it is unknown whether rap music use impacts sexual initiation specifically and, if so, which factors mediate this impact. Thus, we investigated the longitudinal relationship between hours spent listening to rap music in seventh grade and sexual initiation in ninth grade. We also examined the role of perceived peer sexual behavior as a potential mediator of this relationship. We analyzed data from students (n = 443) enrolled in a school-based randomized controlled trial of a sexual health education curriculum collected at baseline and at 18-month follow-up. Rap music use and perceived peer sexual behavior were assessed in seventh grade, whereas sexual initiation was assessed in ninth grade. Univariate, multivariate, and mediation analyses were conducted. At baseline, rap music use was significantly associated with race/ethnicity, parental music rules, and sexual behavior, but not with gender or parental education. Rap music use was a significant predictor of sexual initiation on univariate analysis but not multivariate analysis. Mediation analysis showed that the association between hours spent listening to rap music and sexual initiation was significantly mediated by perceived peer sexual behavior. Rap music use in early adolescence significantly impacts sexual initiation in late adolescence, partially mediated by perceived peer sexual behavior. More research is needed to understand how rap music influences perceptions of peer sexual behavior, which, in turn, influence early sexual initiation.

    Parent-adolescent relationship quality and delay discounting may play important roles in adolescents’ sexual decision making processes, and levels of self-control during adolescence could act as a buffer within these factors. This longitudinal study included 219 adolescent (55% male; mean age = 12.66 years at Wave 1; mean age = 15.10 years at Wave 2) and primary caregiver dyads. Structural equation modeling was utilized to determine whether delay discounting mediated the association between parent-adolescent relationship quality and adolescents’ risky sexual behavior and how this mediated association may differ between those with high versus low self-control. The results revealed parent-adolescent relationship quality plays a role in the development of risky sexual behavior indirectly through levels of delay discounting, but only for adolescents with low self-control. These findings could inform sex education policies and health prevention programs that address adolescent risky sexual behavior. PMID:26202153

    Full Text Available Some individuals experience their first sexual intercourse through physically forced sex, which affects the way they experience and cope with stress. We examined differences in sexual risk behavior, experience of stressors, and use of stress-coping strategies among adolescents in Nigeria based on their history of forced sexual initiation and HIV status.We analyzed data from 436 sexually active 10-19-year-old adolescents recruited through a population-based survey from 12 Nigerian states. Using Lazarus and Folkman's conceptual framework of stress and coping, we assessed if adolescents who reported forced sexual initiation were more likely to report HIV sexual risk practices, to report as stressors events related to social expectations, medical care and body images, and loss and grief, and to use more avoidance than adaptive coping strategies to manage stress. We also assessed if HIV status affected experience of stressors and use of coping strategies.Eighty-one adolescents (18.6% reported a history of forced sexual initiation; these participants were significantly more likely to report anal sex practices (OR: 5.04; 95% CI: 2.14-11.87, and transactional sex (OR: 2.80; 95% CI: 1.56-4.95. Adolescents with no history of forced sexual initiation were more likely to identify as stressors, life events related to social expectations (OR: 1.03; 95% CI: 0.96-1.11 and loss and grief (OR: 1.34; 95% CI: 0.73-2.65, but not those related to medical care and body images (OR: 0.63; 95% CI: 0.34-1.18. They were also more likely to use adaptive responses (OR: 1.48; 95% CI: 0.62-3.50 than avoidance responses (OR: 0.90; 95% CI: 0.49-1.64 to cope with stress, though these differences were not significant. More adolescents with a history of forced sexual initiation who were HIV positive identified as stressors, life events related to medical care and body images (p = 0.03 and loss and grief (p = 0.009.

    Full Text Available Abstract Background Several FIDELIS projects (Fund for Innovative DOTS Expansion through Local Initiatives to Stop TB in Tanzania were conducted by the National Tuberculosis and Leprosy Programme (NTLP during the years 2004-2008 to strengthen diagnostic and treatment services. These projects collected information on treatment delay and some of it was available for research purposes. With this database our objective was to assess the duration and determinants of treatment delay among new smear positive pulmonary tuberculosis (TB patients in FIDELIS projects, and to compare delay according to provider visited prior to diagnosis. Methods Treatment delay among new smear positive TB patients was recorded for each patient at treatment initiation and this information was available and fairly complete in 6 out of 57 districts with FIDELIS projects enrolling patients between 2004 and 2007; other districts had discarded their forms at the time of analysis. It was analysed as a cross sectional study. Results We included 1161 cases, 10% of all patients recruited in the FIDELIS projects in Tanzania. Median delay was 12 weeks. The median duration of cough, weight loss and haemoptysis was 12, 8 and 3 weeks, respectively. Compared to Hai district Handeni had patients with longer delays and Mbozi had patients with shorter delays. Urban and rural patients reported similar delays. Patients aged 15-24 years and patients of 65 years or older had longer delays. Patients reporting contact with traditional healers before diagnosis had a median delay of 15 weeks compared to 12 weeks among those who did not. Patients with dyspnoea and with diarrhoea had longer delays. Conclusion In this patient sample in Tanzania half of the new smear positive pulmonary tuberculosis patients had a treatment delay longer than 12 weeks. Delay was similar in men and women and among urban and rural patients, but longer in the young and older age groups. Patients using traditional healers had

    Full Text Available Abstract Background Comprehensive sex education, including the promotion of consistent condom use, is still an important intervention strategy in tackling unplanned pregnancies, HIV/AIDS and sexually transmitted infections (STIs among Ugandan adolescents. This study examines predictors of the intention to use a condom and the intention to delay sexual intercourse among secondary school students (aged 12–20 in Uganda. Methods A school-based sample was drawn from 48 secondary schools throughout Uganda. Participants (N = 1978 completed a survey in English measuring beliefs regarding pregnancy, STIs and HIV and AIDS, attitudes, social norms and self-efficacy towards condom use and abstinence/delay, intention to use a condom and intention to delay sexual intercourse. As secondary sexual abstinence is one of the recommended ways for preventing HIV, STIs and unplanned pregnancies among the sexually experienced, participants with and without previous sexual experience were compared. Results For adolescents without sexual experience (virgins, self-efficacy, perceived social norms and attitude towards condom use predicted the intention to use condoms. Among those with sexual experience (non-virgins, only perceived social norm was a significant predictor. The intention to delay sexual intercourse was, however, predicted similarly for both groups, with attitudes, perceived social norm and self-efficacy being significant predictors. Conclusions This study has established relevant predictors of intentions of safe sex among young Ugandans and has shown that the intention to use condoms is motivated by different factors depending on previous sexual experience. A segmented approach to intervention development and implementation is thus recommended.

    2007-06-01

    We describe adolescent girls' perceptions of sexual assertiveness and examine the relationship of these perceptions with developmental and interpersonal variables. Cross-sectional analysis. Participants were recruited from a school-based health clinic and local colleges, and through snowballing to participate in a 6-month study examining microbicide acceptability. 106 sexually experienced girls (ages 14 through 21 years). Girls described their demographics, sexual history, and romantic relationships and completed the Sexual Assertiveness Scale for Women (SAS-W), which assesses perceptions of sexual assertiveness: Initiation of Sex, Refusal of Unwanted Sex, and Pregnancy-STD Prevention. Girls perceived themselves as asserting themselves between 50% and 75% of the time with their current or most recent partner. The Initiation subscale was not related to the other two subscales. In final models, girls with a prior pregnancy perceived themselves as initiating sex more than girls without a prior pregnancy. Having a greater number of lifetime partners was related to perceptions of less refusal, whereas greater number of partners, being sexually experienced longer, and engaging in more unprotected sex were related to perceptions of less implementation of preventive methods. None of the relationship variables were related to scores on any subscale. Most of these girls perceived themselves as sexually assertive. Given that sexual experience, not relationship factors, were related to perceptions of sexual assertiveness, the design of counseling messages should incorporate sexual experience. These messages should find effective ways to help girls both to communicate their sexual desires and to enhance their ability to protect themselves.

    1981-09-01

    The luminescense of the luminol-H2O2 system was initiated by either free or membrane-bound horseradish peroxideae (HRP). The instantaneous luminescene decayed rapidly and was followed by the delayed luminescence in the presence of excess luminol. The delayed luminescence was characterized by a chain reaction, in which luminescence intensity increased exponentially. Membrane-bound HRP demonstrated that the delayed luminescence took place even in the absence of HRP if the instantaneous luminescence was initiated by HRP. A mechanism for the nonenzymatic luminescence is proposed and discussed.

    Migration during the formative adolescent years can affect important life-course transitions, including the initiation of sexual activity. In this study, we use life history calendar data to investigate the relationship between changes in residence and timing of premarital sexual debut among young people in urban Kenya. By age 18, 64 percent of respondents had initiated premarital sex, and 45 percent had moved at least once between the ages of 12 and 18. Results of the event history analysis show that girls and boys who move during early adolescence experience the earliest onset of sexual activity. For adolescent girls, however, other dimensions of migration provide protective effects, with greater numbers of residential changes and residential changes in the last one to three months associated with later sexual initiation. To support young people's ability to navigate the social, economic, and sexual environments that accompany residential change, researchers and policymakers should consider how various dimensions of migration affect sexual activity.

    2015-04-01

    This study aimed to investigate the relations of adolescent sexual experiences (particularly early initiation) to a spectrum of emotional/behavioral problems and to probe possible gender difference in such relationships. The 10th (N = 8,842) and 12th (N = 10,083) grade students, aged 16-19 years, participating in national surveys in 2005 and 2006 in Taiwan were included for this study. A self-administered web-based questionnaire was designed to collect information on sociodemographic characteristics, sexual experience, substance use, and the Youth Self-Report Form. For the sexually experienced adolescents, their sexual initiation was classified as early initiation (initiation (16-19 years). Gender-specific multivariate response profile regression was used to examine the relationship between sexual experience and the behavioral syndromes. Externalizing problems, including Rule-breaking Behavior and Aggressive Behavior, were strongly associated with sexual initiation in adolescence; the magnitude of the association increased for earlier sexual initiation, especially for females. As to internalizing problems, the connection was rather heterogeneous. The scores on some syndromes, such as Somatic Complaints and Anxious/Depressed, were higher only for females with early or non-early sexual initiation whereas the score on Withdrawn, along with Social Problems that is neither internalizing nor externalizing, was lower for the sexually experienced adolescents than for the sexually inexperienced ones. We concluded that earlier sexual initiation was associated with a wider range of behavioral problems in adolescents for both genders, yet the increased risk with emotional problems was predominately found in females.

    Full Text Available BACKGROUND: Excessive time between diagnosis and initiation of tuberculosis (TB treatment contributes to ongoing TB transmission and should be minimized. In India, Revised National TB Control Programme (RNTCP focuses on indicator start of treatment within 7 days of diagnosis for patients with sputum smear-positive PTB for monitoring DOTS implementation. OBJECTIVES: To determine length of time between diagnosis and initiation of treatment and factors associated with delays of more than 7 days in smear-positive pulmonary TB. METHODS: Using existing programme records such as the TB Register, treatment cards, and the laboratory register, we conducted a retrospective cohort study of all patients with smear-positive pulmonary TB registered from July-September 2010 in two districts in India. A random sample of patients with pulmonary TB who experienced treatment delay of more than 7 days was interviewed using structured questionnaire. RESULTS: 2027 of 3411 patients registered with pulmonary TB were smear-positive. 711(35% patients had >7 days between diagnosis and treatment and 262(13% had delays >15 days. Mean duration between TB diagnosis and treatment initiation was 8 days (range = 0-128 days. Odds of treatment delay >7 days was 1.8 times more likely among those who had been previously treated (95% confidence interval [CI] 1.5-2.3 and 1.6 (95% CI 1.3-1.8 times more likely among those diagnosed in health facilities without microscopy centers. The main factors associated with a delay >7 days were: patient reluctance to start a re-treatment regimen, patients seeking second opinions, delay in transportation of drugs to the DOT centers and delay in initial home visits. To conclude, treatment delay >7 days was associated with a number of factors that included history of previous treatment and absence of TB diagnostic services in the local health facility. Decentralized diagnostic facilities and improved referral procedures may reduce such treatment

    Foreign-born youth have a lower risk of sexual initiation than native born youth, yet most research has focused on Latinos. An ethnically diverse sample of 200, 14-21 year-old youth were surveyed in Denver in 2014. We used logistic regression models to predict the odds of intentions to have sex and sexual experience, adding covariates that could account for differences in outcomes by immigrant generation. First generation youth were less likely to intend to have sex and to have sexual experience than third generation youth after controlling for racial/ethnic group, suggesting that first generation immigrants of multiple racial/ethnic groups, not just Latinos alone, have a lower risk for sexual initiation. Having a supportive community reduced the odds of sexual intentions and sexual experience. Our findings support future research using a larger sample of black, white, and Asian immigrant youth to corroborate and to explore reasons behind these associations.

    Despite the large number of East Asian youth in Canada, little is known about their health and risk behaviors. We examined the relationship between ethnic identity and sexual initiation among East Asians. This secondary analysis of a population-based survey selected 4,311 students in 7-12th grades who described themselves as East Asian (e.g., Chinese, Japanese, Korean). Gender-stratified logistic regression analyses examined whether ethnic identity was associated with sexual initiation, controlling for age, living situation, and cultural exposure. Boys with stronger commitment to their ethnic groups were less likely to have ever had sexual intercourse (aOR 0.80). Girls with higher levels of ethnic identity exploration were less likely to report sexual initiation (aOR 0.71). Stronger ethnic identity was associated with not having sexual intercourse among East Asian adolescents. The findings suggest the need to consider ethnocultural factors in future research and practice.

    Full Text Available Background. In Haiti, breast cancer patients present at such advanced stages that even modern therapies offer modest survival benefit. Identifying the personal, sociocultural, and economic barriers-to-care delaying patient presentation is crucial to controlling disease. Methods. Patients presenting to the Hôpital Bon Sauveur in Cange were prospectively accrued. Delay was defined as 12 weeks or longer from initial sign/symptom discovery to presentation, as durations greater than this cutoff correlate with reduced survival. A matched case-control analysis with multivariate logistic regression was used to identify factors predicting delay. Results. Of N=123 patients accrued, 90 (73% reported symptom-presentation duration and formed the basis of this study: 52 patients presented within 12 weeks of symptoms, while 38 patients waited longer than 12 weeks. On logistic regression, lower education status (OR = 5.6, P=0.03, failure to initially recognize mass as important (OR = 13.0, P<0.01, and fear of treatment cost (OR = 8.3, P=0.03 were shown to independently predict delayed patient presentation. Conclusion. To reduce stage at presentation, future interventions must educate patients on the recognition of initial breast cancer signs and symptoms and address cost concerns by providing care free of charge and/or advertising that existing care is already free.

  15. Psychosexual therapy for delayed ejaculation based on the Sexual Tipping Point model

    2016-01-01

    The Sexual Tipping Point® (STP) model is an integrated approach to the etiology, diagnosis and treatment of men with delayed ejaculation (DE), including all subtypes manifesting ejaculatory delay or absence [registered trademark owned by the MAP Educational Fund, a 501(c)(3) public charity]. A single pathogenetic pathway does not exist for sexual disorders generally and that is also true for DE specifically. Men with DE have various bio-psychosocial-behavioral & cultural predisposing, precipitating, maintaining, and contextual factors which trigger, reinforce, or worsen the probability of DE occurring. Regardless of the degree of organic etiology present, DE is exacerbated by insufficient stimulation: an inadequate combination of “friction and fantasy”. High frequency negative thoughts may neutralize erotic cognitions (fantasy) and subsequently delay, ameliorate, or inhibit ejaculation, while partner stimulation (friction) may prove unsatisfying. Assessment requires a thorough sexual history including inquiry into masturbatory methods. Many men with DE engage in an idiosyncratic masturbatory style, defined as a masturbation technique not easily duplicated by the partner’s hand, mouth, or vagina. The clinician’s most valuable diagnostic tool is a focused sex history (sex status). Differentiate DE from other sexual problems and review the conditions under which the man can ejaculate. Perceived partner attractiveness, the use of fantasy during sex, anxiety-surrounding coitus and masturbatory patterns require meticulous exploration. Identify important DE causes by juxtaposing an awareness of his cognitions and the sexual stimulation experienced during masturbation, versus a partnered experience. Assist the man in identifying behaviors that enhance immersion in excitation and minimize inhibiting thoughts, in order to reach ejaculation in his preferred manner. Discontinuing, reducing or altering masturbation is often required, which evokes patient resistance

    2008-06-01

    This article presents the initial psychometric properties of a treatment planning and progress inventory for adolescents with sexual behavior problems, the Treatment Progress Inventory for Adolescents Who Sexually Abuse (TPI-ASA). The TPI-ASA was designed to monitor common elements of specialized treatment for youth with sexual behavior problems. The TPI-ASA measures nine dimensions relevant to the evaluation and treatment of adolescents with sexual behavior problems (inappropriate sexual behavior, healthy sexuality, social competency, cognitions supportive of sexual abuse, attitudes supportive of sexual abuse, victim awareness, affective/behavioral regulation, risk prevention awareness, and positive family caregiver dynamics). Members of the Association for the Treatment of Sexual Abusers completed the TPI-ASA with 90 male adolescents with sexual behavior problems as part of a psychosexual evaluation. The preliminary findings provided support for the internal consistency and convergent and discriminant validity of the dimensions. Suggestions are offered for additional research on the TPI-ASA and its potential as a clinical tool.

    2005-01-01

    Objectives. We examined the relation between childhood sexual abuse and injection drug use initiation among young adult injection drug users. Methods. We used mixed effect linear models to compare age at first injection among 2143 young injection drug users by first sexual abuse age categories. Results. The participants were predominantly male (63.3%) and White (52.8%). Mean age and age at first injection were 23.7 and 19.6 years, respectively; 307 participants (14.3%) reported childhood sexual abuse. After adjustment for gender, race/ethnicity, noninjection drug use before first injection drug use, and recruitment site, childhood sexual abuse was independently associated with younger age at first injection. Conclusions. Childhood sexual abuse was associated with earlier initiation of injection drug use. These data emphasize the need to integrate substance abuse prevention with postvictimization services for children and adolescents. PMID:15798133

    2016-05-01

    Little is known about the age of onset of sexual and drug risk and their association with complex patterns of recent drug use among male sex workers (MSW) in a developing country, such as Vietnam. The aim of this study was to determine whether latent class analysis (LCA) would aid in the detection of current individual and polydrug use combinations to predict how different trajectories of sexual and drug initiation contribute to different patterns of current illicit drug use. Data were collected from a cross-sectional survey administered to young MSWs between 2010 and 2011 in Vietnam (N = 710). LCA clustered participants into recent drug use groups, incorporating both the specific types and overall count of different drugs used. Men reported drug use within a 1 month period from an 11-item drug use list. LCA identified three distinct drug use classes: (1) alcohol use, (2) alcohol and tobacco use, and (3) high polydrug use. The current drug use classes are associated with sex worker status, housing stability, income level, educational attainment, marital status, sexual identity, and sexual preferences. High levels of drug use are strongly associated with being a recent sex worker, not having recent stable housing, higher than median income, more than a high school education, less likely to be currently in school and more likely to have non-homosexual preferences and heterosexual partners. An event history analysis approach (time-event displays) examined the timing of the age of onset of drug and sexual risks. Early ages of drug and sexual initiation are seen for all three classes. High current drug users show earlier onset of these risks, which are significantly delayed for moderate and low current drug users. LCA incorporating an overall count of different drugs detected three distinct current drug use classes. The data illustrates that the complexity of drug factors that must be accounted for, both in advancing our epidemiological understanding of the complexity

  2. Stability with respect to initial time difference for generalized delay differential equations

    2015-02-01

    Full Text Available Stability with initial data difference for nonlinear delay differential equations is introduced. This type of stability generalizes the known concept of stability in the literature. It gives us the opportunity to compare the behavior of two nonzero solutions when both initial values and initial intervals are different. Several sufficient conditions for stability and for asymptotic stability with initial time difference are obtained. Lyapunov functions as well as comparison results for scalar ordinary differential equations are employed. Several examples are given to illustrate the theory.

    In this paper we show the measurement of the time delay for the initiation of an emergency shutdown state at the RP-10 Reactor. This time delay is the one corresponding to the delay between the detection of a signal of any fixed limit and the start of a protective action to get the reactor in a safety state. The experimental method used is based on monitoring two signals in an oscilloscope, one signal is the elected initiate event and the other is the de-energizing of electromagnets of the security bars. The time delay for each safety and control rods, was measured for seven energizing current values in a range of 36 - 52 mA. The results showed that the minimum value is (84 {+-} 1.26) ms and the maximum is (108 {+-} 1.60) ms. In all cases it is noted that, the delay time is less than the limit values prefixed down in the reactor safety report. (authors)

    Parent-adolescent relationship quality and delay discounting may play important roles in adolescents' sexual decision making processes, and levels of self-control during adolescence could act as a buffer within these factors. This longitudinal study included 219 adolescent (55 % male; mean age = 12.66 years at Wave 1; mean age = 15.10 years at Wave 2) and primary caregiver dyads. Structural equation modeling (SEM) was utilized to determine whether delay discounting mediated the association between parent-adolescent relationship quality and adolescents' risky sexual behavior and how this mediated association may differ between those with high versus low self-control. The results revealed parent-adolescent relationship quality plays a role in the development of risky sexual behavior indirectly through levels of delay discounting, but only for adolescents with low self-control. These findings could inform sex education policies and health prevention programs that address adolescent risky sexual behavior.

    The value of safe sex may be discounted based on contextual factors associated with an opportunity for sex. College students in a within-subjects study selected hypothetical sexual partners from a set of pictures and classified them based on attractiveness and estimated chance of having an sexually transmitted infection (STI). In the Sexual Delay Discounting (SDD) task, participants rated their likelihood (0-100 %) of waiting for some period of time (e.g., 3 h) to have protected sex with their selected partners, when they could have immediate sex without protection. In the Sexual Probability Discounting (SPD) task, participants rated their likelihood of having protected sex if the opportunity was uncertain (e.g., 50 %), when they could have unprotected sex for sure (100 %). All participants included in the final analyses were aware of and had a positive attitude towards protection against STIs as they were likely to have immediate (or certain) protected sex. Results from 432 delay data in the SDD task and 488 probability data in the SPD task showed that participants' preference for safe sex systematically decreased as the delay to and odds against having safe sex increased. However, this preference was altered by the participants' perception of their partner's attractiveness and STI risk.

  7. [Could phimosis have been the cause of sexual difficulties and delayed fertility of Louis XVI (1754-1793)?].

    2002-02-01

    The great majority of historians agree that the marriage of Louis XVI and Marie-Antoinette was only consumated seven years after the official ceremony. This delay could have been due to a genital malformation (phimosis) of Louis XVI, a strict religious education, a traumatic childhood and the young age of the two spouses, factors that may have inhibited their sexuality. In this article, the authors try to determine whether Louis XVI was able to overcome his sexual difficulties following an operation (circumcision) or as a result of spontaneous cure.

    To develop a scale to measure adolescent beliefs and attitudes about postponing sexual initiation (PSI). A theory-based, 12-item scale measuring beliefs about PSI was developed and administered via a mailed questionnaire to those participants in an ongoing longitudinal cohort study of adolescents who had not yet initiated sexual intercourse. Internal consistency reliability, content validity, factorial validity, and construct validity were assessed using cross-sectional data. Mean age for boys was 14.4 (+/- 1.6) years and for girls 14.3 (+/-1.6) years (range 11 to 19 years), and 93% of respondents were white. The beliefs about PSI rated as most important by both girls and boys were concern about pregnancy and sexually transmitted infection. Cronbach alpha for the scale was 0.83 for girls and 0.88 for boys. Exploratory factor analysis demonstrated that the items loaded on four factors consistent with the theoretical basis of the model and confirmatory factor analysis demonstrated good fit of the overall model. The PSI scale score was associated with hypothesized sociodemographic, psychological, and behavioral variables, supporting construct validity of the scale. A higher score was associated with female gender; age global and social self-esteem; more frequent attendance at religious services; less peer pressure to have sexual intercourse; nonuse of alcohol, illicit drugs, and cigarettes; and no intention to initiate sexual intercourse in the next year. The PSI scale demonstrated satisfactory psychometric properties. Future research is needed to evaluate the utility of this scale in predicting sexual initiation and in interventions aimed at postponing sexual initiation.

  11. Factors predicting the probability of initiating sexual intercourse by context and sex.

    2015-10-01

    Despite men initiating sex more than women there is considerable variance within the sexes. This study is the first to consider the impact of multiple predictors from the literature, and investigates how factors, such as relationship length, sociosexuality, and different aspects of self-perceived mate value among others, independently and interactively predict initiation of sexual intercourse in both short-term sexual and long-term romantic mating contexts, testing predictions from Sexual strategies theory. For long-term relationships, positive partner bond increased initiative to sexual intercourse for women. For men, self-perceived independence increased probability of taking the initiative, while relationship attachment decreased probability. For short-term relations, the desire component of the sociosexual orientation inventory increased probability of initiation for both sexes, while male initiative was increased by pleasure reasons for sex. The impact of individual predictors on initiating intercourse is influenced by being included in a multidimensional model, and relationship context affects the impact of the predictors.

  15. Age at Time of Initial Sexual Intercourse and Health of Adolescent Girls.

    Lara, Lúcia A S; Abdo, Carmita H N

    2016-10-01

    Adolescence is characterized by marked changes in the body, psychology, and sexual behavior due to increasing production of hormones. In this review we aimed to assess the effect of age at the time of first sexual intercourse (sexarche) on the health of adolescent girls, and identify factors that might protect against early initiation of sexual relations in girls. The PubMed, Lilacs, and Google Scholar databases were searched for clinical trials, comparative studies, case-control studies, cross-sectional studies, cohort studies, multicenter studies, observational studies, meta-analyses, and systematic reviews published up to December 2014 on this theme. The search terms were: "sexual debut," "coitarche," "sexarche," and "young people," "adolescent," "unplanned pregnancy," "adolescent contraception," and "STDs." Data were extracted from 28 studies and 41 references were used to introduce the theme and to support the discussion. Sexarche has been occurring in increasingly younger girls. A young age at sexarche can lead to subsequent risky sexual behavior. Girls who have sexarche when they are 14 years old or younger are less likely to use contraception on this occasion, take more time before they start using contraception in subsequent sexual relations, are more likely to have several sex partners, have a higher risk for depression, have lower self-esteem and more episodes of repentance, and have a higher risk for a sexually transmitted disease and cervical cancer. Girls with low educational, socioeconomic, and cultural status, little parental monitoring, parental separation, and absence of religiosity tend to experience sexarche at a younger age. Adolescent girls who postpone sexarche until they are 16 years old are physically and psychologically healthier than those who have sexarche at a younger age. This suggests that providing adolescent girls with appropriate education about sexual relations might reduce the negative effect of sexual relations at a young age.

    Full Text Available Abstract Background There has been little discussion about the importance of oral management and interferon (IFN therapy, although management of the side effects of therapy for chronic hepatitis C has been documented. This study determined whether dental problems delayed the initiation of IFN therapy for hepatitis C virus (HCV-infected patients. Results We analyzed 570 HCV-infected patients who were admitted to our hospital from December 2003 to June 2010 for treatment consisting of pegylated IFN (Peg-IFN monotherapy or Peg-IFN/ribavirin combination therapy. The group comprised 274 men and 296 women with a mean age 57.2 years. Of the 570 patients, six could not commence Peg-IFN therapy, despite their admission, because of dental problems such as periodontitis, pupitis, and pericoronitis. The ages of six whose dental problems delayed the initiation of Peg-IFN ranged from 25 to 67 years, with a mean age of 47.3 ± 15.2 years. IFN therapy was deferred for 61.3 ± 47.7 days. Among the six subjects for whom IFN treatment was delayed, only one had a salivary flow that was lower than the normal value. Conclusions Treatment of dental infections is required before IFN therapy for HCV infection can be started. To increase the depth of understanding of oral health care, it is hoped that dentists and medical specialists in all areas will hold discussions to generate cooperation.

  18. Impact of the initial tropospheric zenith path delay on precise point positioning convergence during active conditions

    Kalita, J. Z.; Rzepecka, Z.

    2017-04-01

    Tropospheric delay is one of the key factors that influence the convergence time of the precise point positioning (PPP) method. Current models do not allow for the fixing of the zenith path delay tropospheric parameter, leaving the difference between nominal and final value to the estimation process. Here, we present an analysis of several PPP result-sets using the tropospheric parameter’s nominal value adopted from models: VMF1, GPT2w, MOPS, and ZERO-WET. The last variant assumes a zero value for the initial wet part of the zenith delay. The PPP results are subtracted from a solution based on the final tropospheric product from the International GNSS Service (IGS). Several days exhibiting the most active tropospheric conditions were selected for each of the 7 stations located in the mid-latitude Central European region. During the active days, application of the VMF1 model increases the resulting height component’s quality by about 33–36% when compared to the GPT2w and MOPS. The respective improvement in VMF1 latitude and longitude components is 27% and 15%. The average relative deterioration in the result standard deviations between active and calm tropospheric conditions reaches about 20–30% of the former. We discuss the impact of the initial tropospheric parameter’s variance and bias on positioning. In addition, we compare the results with those of other studies over the impact of active tropospheric conditions on the PPP method.

  10. Adaptive synchronization under almost every initial data for stochastic neural networks with time-varying delays and distributed delays

    Science.gov (United States)

    Zhu, Quanxin; Cao, Jinde

    2011-04-01

    This paper is concerned with the adaptive synchronization problem for a class of stochastic delayed neural networks. Based on the LaSalle invariant principle of stochastic differential delay equations and the stochastic analysis theory as well as the adaptive feedback control technique, a linear matrix inequality approach is developed to derive some novel sufficient conditions achieving complete synchronization of unidirectionally coupled stochastic delayed neural networks. In particular, the synchronization criterion considered in this paper is the globally almost surely asymptotic stability of the error dynamical system, which has seldom been applied to investigate the synchronization problem. Moreover, the delays proposed in this paper are time-varying delays and distributed delays, which have rarely been used to study the synchronization problem for coupled stochastic delayed neural networks. Therefore, the results obtained in this paper are more general and useful than those given in the previous literature. Finally, two numerical examples and their simulations are provided to demonstrate the effectiveness of the theoretical results.

  11. Recovery from Multiple APAs Delays Gait Initiation in Parkinson’s Disease

    Science.gov (United States)

    Cohen, Rajal G.; Nutt, John G.; Horak, Fay B.

    2017-01-01

    Background: Freezing of gait in Parkinson’s disease (PD) has been linked with deficits in inhibitory control, but causal mechanisms are not established. Freezing at gait initiation (start hesitation) is often accompanied by multiple anticipatory postural adjustments (APAs). If inhibition deficits contribute to freezing by interfering with ability to inhibit initial weight shifts in the wrong direction, then PD subjects should experience more episodes of multiple APAs than healthy controls (HCs) do. If inhibition deficits contribute to freezing by interfering with ability to release a previously inhibited step following multiple APAs, then step onset following multiple APAs should be delayed more in people with PD than in HCs. Methods: Older adults with PD and HC subjects rapidly initiated stepping in response to a light cue in blocks of simple (SRT) and choice (CRT) conditions. We recorded kinematics and ground reaction forces, and we administered the Stroop task to assess inhibitory control. Results: Multiple APAs were more common in CRT than SRT conditions but were equally common in HC and PD subjects. Step onsets were delayed in both conditions and further delayed in trials with multiple APAs, except for HC subjects in SRT trials. Poor Stroop performance correlated with many multiple APAs, late step onset, and rearward position of center of mass (COM) at cue presentation. Forward motion of the COM during the APA was higher in trials with multiple APAs than in trials with single APAs, especially in CRT trials and in PD subjects without self-reported freezing. Conclusion: Start hesitation is not caused by multiple APAs per se, but may be associated with difficulty recovering from multiple APAs, due to difficulty releasing a previously inhibited step.

    The Heart and Stroke Foundation of Ontario's Hypertension Management Initiative (HMI) was a pragmatic implementation of clinical practice guidelines for hypertension management in primary care clinics. The HMI was a prospective delayed phase cohort study of 11 sites enrolling patients in two blocks starting 9 months apart in 2007. The intervention was an evidence-informed chronic disease management program consisting of an interprofessional educational intervention with practice tools to implement the Canadian Hypertension Education Program's clinical practice guidelines. This study compares the change in blood pressure (BP) from baseline to 9 months after the intervention between groups. In the immediate intervention group, the mean BP at baseline was 134.6/79.1 mm Hg (18.2/11.5) and in the delayed intervention group 134.2/77.1 mm Hg (18.9/11.8). The fall in BP in the immediate intervention group from baseline to 9 months after the intervention was 7.3/3.6 mm Hg (95% confidence interval (CI): 5.9-8.7/2.6-4.5) and in the delayed group 8.1/3.3 mm Hg (95% CI: 7.0-9.3/2.5-4.1) (all Phypertension can rapidly lead to lower BP levels.

    The present meta-analysis evaluated the effectiveness of bystander education programs for preventing sexual assault in college communities. Undergraduates trained in bystander education for sexual assault were expected to report more favorable attitudes, behavioral proclivities, and actual behaviors relative to untrained controls. Data from 12 studies of college students (N = 2,926) were used to calculate 32 effect sizes. Results suggested moderate effects of bystander education on both bystander efficacy and intentions to help others at risk. Smaller but significant effects were observed regarding self-reported bystander helping behaviors, (lower) rape-supportive attitudes, and (lower) rape proclivity, but not perpetration. These results provide initial support for the effectiveness of in-person bystander education training. Nonetheless, future longitudinal research evaluating behavioral outcomes and sexual assault incidence is needed.

    Due to clinical benefits, delayed cord clamping (DCC) is recommended in infants born before 37 weeks gestational age. The objective was to institute a delayed cord clamping program and to evaluate clinical outcomes one year after initiation. This study occured at Christiana Care Health System, a tertiary care facility with a 52 bed level 3 Neonatal Intensive Care Unit (NICU). A multidisciplinary team created a departmental policy, a DCC protocol and educational programs to support the development of a DCC program. A year after initiation of DCC, we evaluated two cohorts of very low birth weight (VLBW) infants (cord clamping protocol and a decrease in the percentage of VLBW infants requiring red blood cell transfusion from 53.7 to 35.9 % (p = 0.003). We also found a decreased need for respiratory support in the second cohort with no increases in the balancing measures of admission hypothermia and jaundice requiring phototherapy. During the Control Phase ongoing monitoring and education has led to a 93.7 % compliance rate. A multidisciplinary team including key leadership from the obstetric and pediatric departments allowed for the rapid and safe implementation of DCC.

    One-cell mouse embryos from KM strain and B6C3F1 strain were cultured in M16 medium, in which2-cell block generally occurs. Embryos of KM strain exhibited 2-cell block, whereas B6C3F1 embryos,which are regarded as a nonblocking strain, proceeded to the 4-cell stage in our culture condition. It is oftenassumed that the block of early development is due to the failure of zygotic gene activation (ZGA) in culturedembryos. In this study we examined protein synthesis patterns by two-dimensional gel electrophoresis of[35S] methionine radiolabeled 2-cell embryos. Embryos from the blocking strain and the nonblocking strainwere compared in their development both in vitro and in vivo. The detection of TRC expression, a markerof ZGA, at 42 h post hCG in KM embryos developed in vitro suggested that ZGA was also initiated even inthe 2-cell arrested embryos. Nevertheless, a significant delay of ZGA was observed in KM strain as comparedwith normally developed B6C3F1 embryos. At the very beginning of major ZGA as early as 36 h post hCG,TRC has already been expressed in B6C3F1 embryos developed in vitro and KM embryos developed in vivo.But for 2-cell blocked KM embryos, TRC was still not detectable even at 38 h post hCG. These evidencessuggest that 2-cell-blocked embryos do initiate ZGA, and that 2-cell block phenomenon is due not to thedisability in initiating ZGA, but to a delay of ZGA.

    We examined the prospective association between negative life events and time to initiation of sexual intercourse and the influence of family structure and family income on this association. We followed up a randomly selected sample (n=649) of ethnically diverse parents and their children aged 12 to 17 years over a 5-year period. We conducted Cox proportional hazards regression analysis to examine the relation between negative life events and time to initiation of sexual intercourse. Family structure and family income were assessed as confounders. Negative life events were significant predictors of time to initiation of sexual intercourse in adolescents. After controlling for demographic variables, youths reporting 1 negative life event had a hazard of initiation of sexual intercourse 1.40 times greater and youths reporting 2 or more negative life events had a hazard of initiation of sexual intercourse 1.61 times greater compared with youths reporting no negative life events. Family structure and family income were not significant confounders of the relation between initiation of sexual intercourse and negative life events. Interventions to prevent initiation of sexual intercourse should focus on youths with recent negative life events, regardless of family income and structure.

    Full Text Available Bipolar disorder is a significant cause of morbidity and mortality. Although existing treatments are effective, there is often a substantial delay before diagnosis and treatment initiation. We sought to investigate factors associated with the delay before diagnosis of bipolar disorder and the onset of treatment in secondary mental healthcare.Retrospective cohort study using anonymised electronic mental health record data from the South London and Maudsley NHS Foundation Trust (SLaM Biomedical Research Centre (BRC Case Register on 1364 adults diagnosed with bipolar disorder between 2007 and 2012. The following predictor variables were analysed in a multivariable Cox regression analysis: age, gender, ethnicity, compulsory admission to hospital under the UK Mental Health Act, marital status and other diagnoses prior to bipolar disorder. The outcomes were time to recorded diagnosis from first presentation to specialist mental health services (the diagnostic delay, and time to the start of appropriate therapy (treatment delay.The median diagnostic delay was 62 days (interquartile range: 17-243 and median treatment delay was 31 days (4-122. Compulsory hospital admission was associated with a significant reduction in both diagnostic delay (hazard ratio 2.58, 95% CI 2.18-3.06 and treatment delay (4.40, 3.63-5.62. Prior diagnoses of other psychiatric disorders were associated with increased diagnostic delay, particularly alcohol (0.48, 0.33-0.41 and substance misuse disorders (0.44, 0.31-0.61. Prior diagnosis of schizophrenia and psychotic depression were associated with reduced treatment delay.Some individuals experience a significant delay in diagnosis and treatment of bipolar disorder after initiation of specialist mental healthcare, particularly those who have prior diagnoses of alcohol and substance misuse disorders. These findings highlight a need for further study on strategies to better identify underlying symptoms and offer appropriate treatment

    Full Text Available OBJECTIVES: To determine the length of delay in initial health-seeking in new pulmonary tuberculosis (PTB cases among migrant population in the eastern part of China, and factors associated with it. METHODS: A cross-sectional study was conducted using a structured questionnaire in six counties in Shanghai, Guangdong and Jiangsu from May to October, 2008, to estimate the extent and factors responsible for delayed initial health-seeking of the new PTB cases. The interval between self-reported onset of TB symptoms and date of first attendance at any medical institution was determined. More than the median duration was defined as delayed health-seeking. RESULTS: A total of 323 new migrant PTB patients participated in the study. Only 6.5% had medical insurance. The median and mean durations to initial health-seeking were respectively 10 and 31 days. There was no significant association between socio-demographic factors and delayed initial health-seeking. Average monthly working days >24 (AOR, 1.61; 95% CI, 1.03-2.51, and hemoptysis or bloody sputum (AOR, 0.48; 95% CI, 0.28-0.85 were significantly associated with delayed initial health-seeking. CONCLUSIONS: Interventions to improve health seeking behavior among the migrant population in China must focus on strengthening their labor, medical security and health education.

  4. Initiation of delayed hydride cracking in zirconium-niobium micro pressure tubes

    Science.gov (United States)

    Sundaramoorthy, Ravi Kumar

    Pressure tubes pick up hydrogen while they are in service within CANDU reactors. Sufficiently high hydrogen concentration can lead to hydride precipitation during reactor shutdown/repair at flaws, resulting in the potential for eventual rupture of the pressure tubes by a process called Delayed Hydride Cracking (DHC). The threshold stress intensity factor (KIH) below which the cracks will not grow by delayed hydride cracking of Zr-2.5Nb micro pressure tubes (MPTs) has been determined using a load increasing mode (LIM) method at different temperatures. MPTs have been used to allow easy study of the impact of properties like texture and grain size on DHC. Previous studies on MPTs have focused on creep and effects of stress on hydride orientation; here the use of MPTs for DHC studies is confirmed for the first time. Micro pressure tube samples were hydrided to a target hydrogen content of 100 ppm using an electrolytic method. For DHC testing, 3 mm thick half ring samples were cut out from the tubes using Electrical Discharge Machining (EDM) with a notch at the center. A sharp notch with a root radius of 15 microm was introduced by broaching to facilitate crack initiation. The direct current potential drop method was used to monitor crack growth during the DHC tests. For the temperature range tested the threshold stress intensity factors for the micro pressure tube used were found to be 6.5--10.5 MPa.m 1/2 with the value increasing with increasing temperature. The average DHC velocities obtained for the three different test temperatures 180, 230 and 250°C were 2.64, 10.87 and 8.45 x 10-8 m/s, respectively. The DHC data obtained from the MPTs are comparable to the data published in the literature for full sized CANDU pressure tubes.

    2005-01-01

    The relationship among acculturation-related variables, past sexual activity, and subsequent sexual behavior was examined for a sample of Latino youth in the United States over a 12-month period. A subsample from the National Longitudinal Study of Adolescent Health database was analyzed by means of a prospective design. History of sexual intercourse predicted subsequent sexual behavior over the ensuing 12 months. The acculturation-related variables were related to whether an adolescent reported being sexually active at Wave 1 but in a complex fashion. Among recent immigrants, youth from English-speaking homes were less likely to be sexually active than those from Spanish-speaking homes. The opposite was observed for youth who were born in the United States or who had resided in the United States most of their lives.

    Full Text Available Timely diagnosis and treatment initiation are critical to reduce the chain of transmission of Tuberculosis (TB in places like Mumbai, where almost 60% of the inhabitants reside in overcrowded slums. This study documents the pathway from the onset of symptoms suggestive of TB to initiation of TB treatment and examines factors responsible for delay among uncomplicated pulmonary TB patients in Mumbai.A population-based retrospective survey was conducted in the slums of 15 high TB burden administrative wards to identify 153 self-reported TB patients. Subsequently in-depth interviews of 76 consenting patients that fit the inclusion criteria were undertaken using an open-ended interview schedule. Mean total, first care seeking, diagnosis and treatment initiation duration and delays were computed for new and retreatment patients. Patients showing defined delays were divided into outliers and non-outliers for all three delays using the median values.The mean duration for the total pathway was 65 days with 29% of patients being outliers. Importantly the mean duration of first care seeking was similar in new (24 days and retreatment patients (25 days. Diagnostic duration contributed to 55% of the total pathway largely in new patients. Treatment initiation was noted to be the least among the three durations with mean duration in retreatment patients twice that of new patients. Significantly more female patients experienced diagnostic delay. Major shift of patients from the private to public sector and non-allopaths to allopaths was observed, particularly for treatment initiation.Achieving positive behavioural changes in providers (especially non-allopaths and patients needs to be considered in TB control strategies. Specific attention is required in counselling of TB patients so that timely care seeking is effected at the time of relapse.

    2015-01-01

    We examined the association between adolescent sexual debut and age at new-type drug initiation among a sample of young adult new-type drug users. A total of 276 participants were recruited using respondent-driven sampling (RDS) in Shanghai, China. The analyses were restricted to a total of 201 participants aged between 18 and 30 years. The average age at sexual debut and age at first new-type drug use were 18.8 and 20.9 years, respectively. About 94% of participants reported having sexual experience (n=188); of those, 137 (72.9%) had sexual debut before they first used new-type drugs, while 32 (17.0%) initiated both events at the same age. After adjustment for age, income, education, and sexual orientation, adolescent sexual debut was independently associated with younger age at new-type drug initiation. Adolescent sexual debut is associated with early onset of new-type drug use. Our findings underscore the importance of implementing sex-education programs for adolescents in schools in China.

METHODS: Individuals from the 1982 birth cohort (N=4,297 were interviewed in 2004-5, city of Pelotas, Southern Brazil. Early sexual initiation (<13 years of age was the outcome. Descriptive and stratified analyses were performed according to sex. Variables analyzed were family income in 1982, ethnicity, young adult's level of education and change in income (between 1982 and 2004-5. Ethnographic data were used to complement result analysis. RESULTS: Prevalence of early sexual initiation was higher among black and mixed men, and those with low level of education and low family income in 1982 and 2004-5. More traditional male sexual role requirements, such as virility and sexual initiative, showed more repercussion and adherence from an early age among men. Young family women with higher income and level of education tended to delay their sexual initiation. Imposition of traditional values was found to influence early sexual initiation among men and women with lower level of education and income. CONCLUSIONS: Results found re-established the economic factor as a determinant of behavior or uses of sexuality for both sexes. To focus on political efforts that help the economically disadvantaged to have opportunities and egalitarian future perspectives is an important strategy for health

  12. Gender-Specificity of Initial and Controlled Visual Attention to Sexual Stimuli in Androphilic Women and Gynephilic Men.

    Samantha J Dawson

    Full Text Available Research across groups and methods consistently finds a gender difference in patterns of specificity of genital response; however, empirically supported mechanisms to explain this difference are lacking. The information-processing model of sexual arousal posits that automatic and controlled cognitive processes are requisite for the generation of sexual responses. Androphilic women's gender-nonspecific response patterns may be the result of sexually-relevant cues that are common to both preferred and nonpreferred genders capturing attention and initiating an automatic sexual response, whereas men's attentional system may be biased towards the detection and response to sexually-preferred cues only. In the present study, we used eye tracking to assess visual attention to sexually-preferred and nonpreferred cues in a sample of androphilic women and gynephilic men. Results support predictions from the information-processing model regarding gendered processing of sexual stimuli in men and women. Men's initial attention patterns were gender-specific, whereas women's were nonspecific. In contrast, both men and women exhibited gender-specific patterns of controlled attention, although this effect was stronger among men. Finally, measures of attention and self-reported attraction were positively related in both men and women. These findings are discussed in the context of the information-processing model and evolutionary mechanisms that may have evolved to promote gendered attentional systems.

    Lesbian, gay, bisexual, and transgender (LGBT) youth experience multiple sexual health inequities driven, in part, by deficits in parental and peer support, school-based sex education programs, and community services. Research suggests that the Internet may be an important resource in the development of sexual health among LGBT youth. We examined the feasibility of recruiting youth in same-sex relationships into an online sexual health intervention, evaluated intervention acceptability, and obtained initial estimates of intervention efficacy. LGBT youth (16 to 20 years old) completed Queer Sex Ed (QSE), an online, multimedia sexual health intervention consisting of five modules. The final sample (N = 202) completed the pretest, intervention, and posttest assessments. The primary study outcomes were sexual orientation identity and self-acceptance (e.g., coming-out self-efficacy), sexual health knowledge (e.g., sexual functioning), relationship variables (e.g., communication skills), and safer sex (e.g., sexual assertiveness). Analyses indicated that 15 of the 17 outcomes were found to be significant (p LGBT youth.

    Cervical cancer ranks as the fourth leading cause of cancer death in women worldwide. In Taiwan, although the universal health insurance system has achieved 99.9% coverage and ensured easy access to medical care, some cervical cancer patients continue to delay initiation of definitive treatment after diagnosis. This study focused on cervical cancer patients who delayed treatment for at least 4 months, and examined the characteristics, related factors, and survival in these patients.Data on patients with a new confirmed diagnosis of cervical cancer by the International Federation of Gynecology and Obstetrics (FIGO) staging system between 2005 and 2010 were obtained from the National Health Insurance Research Database and the Taiwan Cancer Registry. Logistic regression analysis was performed to analyze the association of various factors with treatment delay. The Cox proportional hazards model was used to analyze the effects of various factors on mortality risk.The rate of treatment delay for cervical cancer decreased steadily from 6.46% in 2005 to 2.48% in 2010. Higher rates of treatment delay were observed among patients who were aged ≥75 years (9.91%), had severe comorbidity, had stage IV (9.50%), diagnosing hospital level at nonmedical center, or at public hospital ownership. Factors that correlated with treatment delay were age ≥75 years (odds ratio [OR] = 2.42), higher comorbidity Charlson comorbidity index (CCI) 4-6, or ≥7 (OR = 1.60, 2.00), cancer stage IV (OR = 2.60), the diagnosing hospital being a regional, district hospital, or other (OR = 3.00, 4.01, 4.60), and at public hospital ownership. Those who delayed treatment had 2.31 times the mortality risk of those who underwent timely treatment (P cervical cancer treatment in Taiwan was associated with age, comorbidity, cancer stage, diagnosing hospital level, and hospital ownership. Delaying treatment for ≥4 months substantially raised mortality risk in cervical cancer patients.

    Context The association between early sexual initiation and parenting practices (e.g., support and knowledge) has not been tested in multiple European population-based samples using the same instrument. Methods Data provided by females (age 14-16) participating in the 2005-06 Health Behaviors in School-Aged Children (HBSC) survey conducted in Austria, Finland, Greece, Hungary, Iceland, Lithuania, Romania, Spain and Ukraine were used (n=7,466). The dependent variable was early sexual initiation (<16). The main independent variables were maternal and paternal support and knowledge of daily activities. Univariate, bivariate and multivariable analyses were run with standard error corrections and weights. Results Prevalence of early sexual initiation ranged from a low of 7% (Romania) to a high of 35% (Iceland). In bivariate analyses, maternal and paternal support were significantly negatively related to adolescent females’ early sexual initiation in a majority of countries. In models with demographic controls, parental support was significantly negatively related to early sexual initiation (AOR = 0.80 maternal, 0.74 paternal). After adding parental knowledge, early sexual initiation was no longer associated with parental support, but was significantly negatively related to parental knowledge (AOR = 0.69 maternal and paternal). These patterns held across countries. Conclusions Negative associations between parental support and early initiation were largely explained by parental knowledge, suggesting either that knowledge is more important than support or that knowledge mediates the association between support and early initiation. Providers should counsel parents regarding the importance of knowledge of their daughters’ daily lives, which may be enhanced through developing supportive relationships. PMID:22958661

    Researchers examining injection drug users (IDUs) in drug treatment have been trying for decades to determine the optimal way to intervene to prevent the transmission and spread of human immunodeficiency virus (HIV) in this population. Although efficacious HIV risk reduction interventions are widely available, questions remain about what specific factors are most related to HIV risk behavior and defined as unprotected sexual activity and/or high risk drug use. This review involved an evaluation of the research literature in order to better understand the association between drug use and sexual behavior debut on HIV risk behavior. Findings suggest that drug use debut and sexual behavior debut may be related to subsequent HIV risk behavior. Evidence to date implies that intervening at an earlier age to assist youth to avoid or delay these high risk behaviors may be an additional means of reducing subsequent HIV risk.

    Our objective was to assess the value of delayed contrast-enhanced T1-weighted spin-echo MR imaging in the detection of residual cholesteatoma in patients who have undergone canal wall-up tympanoplasty procedure. The MR imaging was obtained prior to revision surgery in 18 patients with opacity of the post-operative cavity at CT examination 12-18 months after canal wall-up tympanoplasty. In each patient the following was performed: precontrast T1- and T2-weighted images; and early and delayed contrast-enhanced axial and coronal T1-weighted imaging. Early and delayed MR imaging results were separately compared with surgical second-look findings. Sensitivity, specificity, and predictive values were evaluated for early and delayed post-contrast MR imaging, compared with second-look surgery findings. A residual cholesteatoma was correctly identified in 8 of 9 cases with delayed contrast-enhanced T1-weighted MR imaging. Mean sensitivity, specificity, positive predictive value, and interobserver agreement (evaluated by kappa statistics) were, respectively, 85.2, 92.6, 92.6%, and kappa=0.78 for the delayed contrast-enhanced MR imaging technique. The same parameters were, respectively, 96.3, 33.3, 60.6, and 0.30 for the early contrast-enhanced T1-weighted MR images. We conclude that delayed contrast-enhanced T1-weighted MR imaging is reliable for the detection of residual cholesteatomas of the middle ear in patients who have undergone canal wall-up tympanoplasty.

    Double fertilization, uniquely observed in plants, requires successful sperm cell delivery by the pollen tube to the female gametophyte, followed by migration, recognition and fusion of the two sperm cells with two female gametic cells. The female gametophyte not only regulates these steps but also controls the subsequent initiation of seed development. Previously, we reported that loss of LORELEI, which encodes a putative glycosylphosphatidylinositol (GPI)-anchored protein, in the female reproductive tissues causes a delay in initiation of seed development. From these studies, however, it was unclear if embryos derived from fertilization of lre-5 gametophytes continued to lag behind wild-type during seed development. Additionally, it was not determined if the delay in initiation of seed development had any lingering effects during seed germination. Finally, it was not known if loss of LORELEI function affects seedling development given that LORELEI is expressed in eight-day-old seedlings. Here, we showed that despite a delay in initiation, lre-5/lre-5 embryos recover, becoming equivalent to the developing wild-type embryos beginning at 72 hours after pollination. Additionally, lre-5/lre-5 seed germination, and seedling and root development are indistinguishable from wild-type indicating that loss of LORELEI is tolerated, at least under standard growth conditions, in vegetative tissues.

Here, we showed that despite a delay in initiation, lre-5/lre-5 embryos recover, becoming equivalent to the developing wild-type embryos beginning at 72 hours after pollination. Additionally, lre-5/lre-5 seed germination, and seedling and root development are indistinguishable from wild type indicating that loss of LORELEI is tolerated, at least under standard growth conditions, in vegetative tissues.

    Sexual plant reproduction is a critical developmental step in the life cycle of higher plants, to allow maternal and paternal genes to be transmitted in a highly regulated manner to the next generation. During evolution, a whole set of signal transduction machinery is developed by plants to ensure an error-free recognition between male and female gametes and initiation of zygotic program. In the past few years, the molecular machineries underlying this biological process have been elucidated, particularly on the importance of synergid cells in pollen tube guidance, the Ca++ spike as the immediate response of fertilization and the epigenetic regulation of parental gene expressions in early zygotic embryogenesis. This review outlines the most recent development in this area.

    Amaral, Marta Araújo; da Fonseca, Rosa Maria Godoy Serpa

    2006-12-01

    This article discusses one of the emergent themes of a qualitative research carried out with female adolescents in the neighborhood of Acaba Mundo, in the city of Belo Horizonte, State of Minas Gerais, and aims at understanding their social representations on sexual initiation concerning gender. The data was collected in four workshops and analyzed on the basis of the social representation theory by means of the discourse analysis technique. Two empirical categories and their consequences emerged from the discourse: leaving childhood behind and fear of pregnancy. The understanding of the social representations and of the gender relationships made the values, ideas and practices of the adolescents and their family clear. It also made clear that those values, ideas and practices were in frequent transformation in the social field.

    The flaw evaluation procedure for Delayed Hydride Cracking (DHC) initiation currently provided in the CSA Standard N285.8 was developed for hydride ratcheting conditions, in which flaw-tip hydrides do not completely dissolve at peak temperature. Test results have shown that hydrided regions formed under non-ratcheting conditions, in which flaw-tip hydrides completely dissolve at peak temperature, have significantly higher resistance to cracking than those formed under ratcheting conditions. This paper presents some preliminary work on the development of a procedure for the evaluation of DHC initiation for flaws under hydride non-ratcheting conditions. (author)

    The present study tested the prediction that male teachers are judged more harshly than female teachers for engaging in heterosexual intercourse with a student. One-hundred and eighty-seven adults (116 women, 71 men) evaluated a hypothetical newspaper article describing an alleged student-teacher relationship as part of a 2 (Gender Dyad: Male Teacher/Female Student or Female Teacher/Male Student) x 2 (Initiator: Student or Teacher) between-subjects design. As expected, a reverse sexual double standard was revealed, in which participants judged situations involving male teachers more harshly than they judged situations involving female teachers, but only when the sexual contact was teacher-initiated. Participants also believed that male students received more social benefits from the sexual contact than did female students.

  6. Orexin mediates initiation of sexual behavior in sexually naïve male rats, but is not critical for sexual performance

    OpenAIRE

    2010-01-01

    The hypothalamic neuropeptide orexin mediates arousal, sleep, and naturally rewarding behaviors, including food intake. Male sexual behavior is altered by orexin receptor-1 agonists or antagonists, suggesting a role for orexin-A in this naturally rewarding behavior. However, the specific role of endogenous orexin-A or B in different elements of male sexual behavior is currently unclear. Therefore, the current studies utilized markers for neural activation and orexin cell-specific lesions to t...

    The present study investigated delay discounting and probability discounting—behavioral economic indices of impulsivity and risk proneness, respectively—in 39 healthy older adults and 25 older adults with mild cognitive impairment (MCI). Relative to the healthy group, it was hypothesized that older adults with MCI would display greater levels of impulsivity, risk proneness, and response inconsistency. The MCI group was found to display a unique delay discounting profile characterized by increasing impulsivity with decreasing reward magnitude, such that cognitively impaired older adults were significantly more impulsive than healthy controls at the small reward magnitude. The two groups exhibited similar levels of probability discounting, though older adults with MCI were significantly less consistent in their risk preferences. The present findings shed light onto decision-making in pre-dementia disease stages and suggest that discounting performance holds potential to complement early diagnostic instruments, likely due to pathophysiological processes in relevant brain regions.

    The objective of this study is to verify the influence of messages Salvadorian youth receive about sexuality, affection, and leisure from family, friends, and the media on the initiation of sexual activity. Cross-sectional study based on a representative sample of 2 615 students (from 13 to 19 years of age) in El Salvador. A random systematic sampling was used to select 30 schools. Sociodemographic aspects, lifestyles, and sources of information on sexuality and love used by the young people were collected. The average age of the young people studied was 15 (SD = 1.8). In all, 638 (24.4%) of the young people stated that they had had sexual relations. The following factors are associated with a greater probability of having had sexual relations: a perception that siblings (OR = 1.8, CI 95%: 1.2-2.7) or friends (OR = 1.7, CI 95%: 1.3-2.2) encourage them to have sex. Protective factors were found to be the supervision of parents (OR = 0.5, CI 95%: 0.4-0.7); messages received from friends that encourage abstinence (OR = 0.7, CI 95%: 0.6-1.0) or from siblings (OR = 0.7, CI 95%: 0.5-0.8); and favorable messages related to marriage received from parents (OR = 0.4, CI 95%: 0.3-0.6). Messages from family and friends are factors that seem to influence the initiation of sexual activity by young people. Sexual health promotion programs in El Salvador should take these factors into account.

    Full Text Available Abstract Background For antiretroviral therapy (ART naive human immunodeficiency virus (HIV infected adults suffering from tuberculosis (TB, there is uncertainty about the optimal time to initiate highly active antiretroviral therapy (HAART after starting antituberculosis treatment (ATT, in order to minimize mortality, HIV disease progression, and adverse events. Methods In a randomized, open label trial at All India Institute of Medical Sciences, New Delhi, India, eligible HIV positive individuals with a diagnosis of TB were randomly assigned to receive HAART after 2-4 or 8-12 weeks of starting ATT, and were followed for 12 months after HAART initiation. Participants received directly observed therapy short course (DOTS for TB, and an antiretroviral regimen comprising stavudine or zidovudine, lamivudine, and efavirenz. Primary end points were death from any cause, and progression of HIV disease marked by failure of ART. Findings A total of 150 patients with HIV and TB were initiated on HAART: 88 received it after 2-4 weeks (early ART and 62 after 8-12 weeks (delayed ART of starting ATT. There was no significant difference in mortality between the groups after the introduction of HAART. However, incidence of ART failure was 31% in delayed versus 16% in early ART arm (p = 0.045. Kaplan Meier disease progression free survival at 12 months was 79% for early versus 64% for the delayed ART arm (p = 0.05. Rates of adverse events were similar. Interpretation Early initiation of HAART for patients with HIV and TB significantly decreases incidence of HIV disease progression and has good tolerability. Trial registration CTRI/2011/12/002260

    Sexual assertiveness is an issue of interest in the context of gender equality and sexual health. This study investigated the social tuning hypothesis that encountering a gender-traditional partner would lead to stronger gender-typical behavior, i.e., respectively, higher and lower levels of taking sexual initiative among men and women. Participants (N = 271) read a vignette describing a romantic partner, who was either presented as gender-traditional or not, followed by a sexual scenario. Subsequently, participants were asked about their expectations toward their own sexual initiative taking. Results showed a significant 'target gender-traditionality × participant gender × participant gender-typicality (masculinity/femininity)' interaction meaning that less gender-typical men were more likely to initiate sexual contact in the experimental, compared to the control condition. Men low in masculine characteristics showed higher initiative taking in response to a gender-traditional target female. We conclude that less gender-typical men seem to employ more social tuning toward their sexual partner, whereas more gender-typical men seem to adhere to their gender-typical behavior regardless of perceived partner characteristics. These results were not seen among the women in the sample. These findings are a starting point for the further development of experimental investigations regarding the gendered nature of both sexual initiative taking and sexual assertiveness in general.

    Purpose: In arterial hypertension left ventricular hypertrophy comprises myocyte hypertrophy, interstitial fibrosis and structural alterations of the coronary microcirculation. MRI enables the detection of myocardial fibrosis, infarction and scar tissue by delayed enhancement (DE) after contrast media application. Aim of this study was to investigate patients with arterial hypertension but without known coronary disease or previous myocardial infarction to detect areas of DE. Methods and material: Twenty patients with arterial hypertension with clinical symptoms of myocardial ischemia, but without history of myocardial infarction and normal coronary arteries during coronary angiography were investigated on a 1.0 T superconducting magnet (Gyroscan T10-NT, Intera Release 8.0, Philips). Fast gradient-echo cine sequences and T2-weighted STIR-sequences were acquired. Fifteen minutes after injection of Gadobenate dimeglumine inversion recovery gradient-echo sequences were performed for detection of myocardial DE. Presence or absence of DE on MRI was correlated with clinical data and the results of echocardiography and electrocardiography, respectively. Results: Nine of 20 patients showed DE in the interventricular septum and the anteroseptal left ventricular wall. In 6 patients, DE was localized intramurally and in 3 patients subendocardially. There was a significant correlation between myocardial DE and ST-segment depressions during exercise and between DE and left-ventricular enddiastolic pressure. Patients with intermittent atrial fibrillation showed a myocardial DE more often than patients without atrial fibrillation. Conclusion: In our series, 45% of patients with arterial hypertension showed DE on cardiac MRI. In this clinical setting, delayed enhancement may be due to coronary microangiopathy. The more intramurally localization of DE, however, rather indicates myocardial interstitial fibrosis.

    -sectional study con-ducted with 222 15 to 19 year-old female adolescents who lived in the area of a family health unit in the East part of the city of São Paulo. The aim was to describe their motivation for starting sexual life or remaining virgin, as well as the associated factors to the onset of sexual life. The girls that had already initiated their sexual life were older, did not cohabitate with both parents, were out of school, lived in illegally-occupied houses and were dating in a higher proportion than the virgin ones. It was also observed a decrease in the value of virginity, but the first intercourse independently of marriage seemed to be acceptable only when there was a romantic relationship with the partner, showing that traditional gender relations continue to be the basis for those girls' sexual behavior.

    Full Text Available Despite the current diagnostic and serologic testing for SLE, the interval between the onset of symptoms and the diagnosis is still long. In this study, we aimed to show the interval between the initial symptoms and the diagnosis of SLE and to investigate the presence of any relationship between the interval and the initial symptoms. One hundred and thirty-six patients were diagnosed with SLE using the 1982 ARA criteria. The mean age of the patients at diagnosis was 29.9 +/- 10.5 years. The mean interval between the onset of symptoms and the diagnosis of SLE was 21.82 +/- 30.32 months. The subjects were evaluated twice, at intervals of < or = 3 and < or = 12 months after the onset of symptoms. Although arthritis and/or arthralgia were the most common initial symptoms (60.3%, only 26.8% of the patients with these symptoms were diagnosed earlier than 3 months after the onset. If the first initial symptoms were butterfly rash or pericarditis, pleuritis, spontaneous abortion or cognitive dysfunction, they led to early diagnosis. In conclusion, since arthritis and/or arthralgia are the most common initial symptoms of the disease, every young woman with these symptoms should be carefully evaluated for SLE.

    To examine the association between sexual orientation identity and human papillomavirus (HPV) vaccination initiation and completion among both women and men. Using data from the 2013 and 2014 National Health Interview Survey, we estimated logistic regression models for the association between sexual orientation identity and HPV vaccination initiation (≥1 dose) and completion (≥3 doses) among US women and men in relation to sociodemographic and healthcare factors. Analyses were restricted to individuals for whom the HPV vaccine was recommended at some point in their lives, namely women aged 18-34 years (n = 9,734) and men aged 18-31 years (n = 6,812). Among all women, bisexual women had higher adjusted odds of HPV vaccination initiation [(odds ratio) 1.71; (95 % confidence interval) 1.20-2.45] and completion (1.59; 1.05-2.42) than heterosexual women. No difference was observed in the odds of HPV vaccination initiation or completion between lesbian and heterosexual women. Among women who had initiated HPV vaccination, lesbians had lower adjusted odds of completion than heterosexual women (0.41; 0.19-0.90). Among all men, gay men had higher adjusted odds of initiating (2.07; 1.17-3.52) and completing (3.90; 1.68-9.06) HPV vaccination than heterosexual men. No difference was observed in the odds of HPV vaccination initiation or completion between bisexual and heterosexual men. Among men who had initiated HPV vaccination, gay (4.36; 1.28-14.83) and bisexual (20.92; 2.34-186.73) men had higher adjusted odds of completion than heterosexual men, although these results are unreliable and should be interpreted with caution. Interventions are needed to promote HPV vaccination among all US women and men, regardless of sexual orientation identity.

    Indonesia has had more recorded human cases of influenza A H5N1 than any other country, with one of the world's highest case fatality rates. Understanding barriers to treatment may help ensure life-saving influenza-specific treatment is provided early enough to meaningfully improve clinical outcomes. Data for this observational study of humans infected with influenza A H5N1 were obtained primarily from Ministry of Health, Provincial and District Health Office clinical records. Data included time from symptom onset to presentation for medical care, source of medical care provided, influenza virology, time to initiation of influenza-specific treatment with antiviral drugs, and survival. Data on 124 human cases of virologically confirmed avian influenza were collected between September 2005 and December 2010, representing 73% of all reported Indonesia cases. The median time from health service presentation to antiviral drug initiation was 7.0 days. Time to viral testing was highly correlated with starting antiviral treatment (p influenza H5N1 in Indonesia appear related to delays in diagnosis rather than presentation to health care settings. Either cases are not suspected of being H5N1 cases until nearly one week after presenting for medical care, or viral testing and/or antiviral treatment is not available where patients are presenting for care. Health system delays have increased since 2007.

    Phenology is considered one of the most robust indicators of the biological impacts of global change. In temperate and boreal regions, long-term data show that rising temperatures are advancing spring onset (e.g. budburst and flowering) and delaying autumn senescence (e.g. leaf coloration and leaf fall) in a wide range of ecosystems. While warm and cold temperatures, day length and insolation, precipitation and water availability, and other factors, have all been shown to influence plant phenology, the future response of phenology to rising temperatures and elevated CO2 still remains highly uncertain because of the challenges associated with conducting realistic manipulative experiments to simulate future environmental conditions. At the SPRUCE (Spruce and Peatland Responses Under Climatic and Environmental Change) experiment in the north-central United States, experimental temperature (0 to +9° C above ambient) and CO2 (ambient and elevated) treatments are being applied to mature, and intact, Picea mariana-Sphagnum spp. bog communities in their native habitat through the use of ten large (approximately 12 m wide, 10 m high) open-topped enclosures. We are tracking vegetation green-up and senescence in these chambers, at both the individual and whole-community level, using repeat digital photography. Within each chamber, digital camera images are recorded every 30 minutes and uploaded to the PhenoCam (http://phenocam.sr.unh.edu) project web page, where they are displayed in near-real-time. Image processing is conducted nightly to extract quantitative measures of canopy color, which we characterize using Gcc, the green chromatic coordinate. Data from a camera mounted outside the chambers (since November 2014) indicate strong seasonal variation in Gcc for both evergreen shrubs and trees. Shrub Gcc rises steeply in May and June, and declines steeply in September and October. By comparison, tree Gcc rises gradually from March through June, and declines gradually from

    The human male psychosexual cycle consists of four phases: excitation, plateau, orgasm, and resolution. Identification of the specific neural substrates of each phase may provide information regarding the brain's pathophysiology of sexual dysfunction. We previously analyzed regional cerebral blood flow (rCBF) with H(2)15O-positron emission tomography (PET) during the excitation phase (initiation of penile erection) induced by audiovisual sexual stimuli (AVSS) and identified activation of the cerebellar vermis, the bilateral extrastriate cortex, and right orbitofrontal cortex, suggesting a role of cognition/emotion in the excitement phase. In the present study, we analyzed rCBF of the same six healthy volunteers during the plateau phase (maintenance of penile erection) induced by AVSS and compared the results with those of the excitation phase. Penile rigidity was monitored in real time with RigiScan Plus during PET scanning. Images were analyzed by statistical parametric mapping (SPM) software, and rCBF in the amygdala, hypothalamus, anterior cingulate, and insula was measured. During the plateau phase, primary subcortical activation was noted in the right ventral putamen, indicating motivational factors in the sexual response via the limbic reward circuit. A significant increase in rCBF in the left hypothalamus was also observed during the plateau phase. The right anterior cingulate and left insula were specifically activated during the excitation phase but not during the plateau phase. These results indicate a significant role of the ventral putamen and the hypothalamus in the plateau phase and confirm that paralimbic and limbic components of the human brain differentially coordinate the sexual response in a psychosexual phase-dependent manner.

    Conclusions: The literature is limited to the evaluation of explicit curricula. The wider cultural competence literature offers further insight by highlighting the importance of broad and embedded forces including social influences, the institutional climate, and the implicit, or hidden, curriculum. A combined interpretation of the complementary cultural competence and sexual and gender diversity literature provides a novel understanding of the optimal content and context for the delivery of a successful curricular initiative.

  6. Sexual experience promotes adult neurogenesis in the hippocampus despite an initial elevation in stress hormones.

    Directory of Open Access Journals (Sweden)

    Benedetta Leuner

    Full Text Available Aversive stressful experiences are typically associated with increased anxiety and a predisposition to develop mood disorders. Negative stress also suppresses adult neurogenesis and restricts dendritic architecture in the hippocampus, a brain region associated with anxiety regulation. The effects of aversive stress on hippocampal structure and function have been linked to stress-induced elevations in glucocorticoids. Normalizing corticosterone levels prevents some of the deleterious consequences of stress, including increased anxiety and suppressed structural plasticity in the hippocampus. Here we examined whether a rewarding stressor, namely sexual experience, also adversely affects hippocampal structure and function in adult rats. Adult male rats were exposed to a sexually-receptive female once (acute or once daily for 14 consecutive days (chronic and levels of circulating glucocorticoids were measured. Separate cohorts of sexually experienced rats were injected with the thymidine analog bromodeoxyuridine in order to measure cell proliferation and neurogenesis in the hippocampus. In addition, brains were processed using Golgi impregnation to assess the effects of sexual experience on dendritic spines and dendritic complexity in the hippocampus. Finally, to evaluate whether sexual experience alters hippocampal function, rats were tested on two tests of anxiety-like behavior: novelty suppressed feeding and the elevated plus maze. We found that acute sexual experience increased circulating corticosterone levels and the number of new neurons in the hippocampus. Chronic sexual experience no longer produced an increase in corticosterone levels but continued to promote adult neurogenesis and stimulate the growth of dendritic spines and dendritic architecture. Chronic sexual experience also reduced anxiety-like behavior. These findings suggest that a rewarding experience not only buffers against the deleterious actions of early elevated

    Repeatedly seen or heard statements are typically judged to be more valid than statements one has never encountered before. This phenomenon has been referred to as the truth effect. We conducted two experiments to assess the plasticity of the truth effect under different contextual conditions. Surprisingly, we did not find a truth effect in the typical judgment design when using a ten minutes interval between statement repetitions. However, we replicated the truth effect when changing the judgment task at initial statement exposure or when using an interval of one week rather than ten minutes. Because none of the current truth effect theories can fully account for these context effects, we conclude that the cognitive processes underlying truth judgments are more complex than has hitherto been assumed. To close the theoretical gap, we propose a revised fluency attribution hypothesis as a possible explanation of our findings. Copyright © 2013 Elsevier Inc. All rights reserved.

    Latina young adults are disproportionately at risk for sexually transmitted infections (e.g., HIV). However, little is known about social and cultural factors contributing to sexual health disparities among young adult Latina recent immigrants. The present study examined social and cultural factors contributing to sexual risk behaviors among 530 Latina women (ages 18-23) who immigrated to Miami-Dade County, Florida, approximately 12 months before assessment. At the cultural/macrosystemic level, participants who reported more sexual risk behaviors tended to (a) be less acculturated; (b) use less positive religious coping; (c) endorse to a greater extent the marianismo belief that Latinas should be the pillar of the family; and (d) endorse less of the marianismo belief that Latinas should be virtuous and chaste (i.e., abstain from premarital sex). As for individual-level factors, participants who reported more sexual risk behaviors also indicated (e) older age, (f) being married/partnered, (g) being employed, (h) living in the US longer, and (i) drinking more alcohol. Findings indicate areas for HIV/STI prevention for this underserved population.

    Behavioral research and prevention intervention science efforts have largely been based on hypotheses of linear or rational behavior change. Additional advances in the field may result from the integration of quantum behavior change and catastrophe models. Longitudinal data from a randomized trial for 1241 pre-adolescents 9-12 years old who self-described as virgin were analyzed. Data for 469 virgins in the control group were included for linear and cusp catastrophe models to describe sexual initiation; data for the rest in the intervention group were added for program effect assessment. Self-reported likelihood to have sex was positively associated with actual initiation of sex (OR = 1.72, 95% CI: 1.43-2.06, R² = 0.13). Receipt of a behavioral prevention intervention based on a cognitive model prevented 15.6% (33.0% vs. 48.6%, OR = 0.52, 95% CI: 0.24-1.11) of the participants from initiating sex among only those who reported 'very likely to have sex.' The beta coefficients for the cubic term of the usp assessing three bifurcating variables (planning to have sex, intrinsic rewards from sex and self-efficacy for abstinence) were 0.0726, 0.1116 and 0.1069 respectively; R² varied from 0.49 to 0.54 (p sexual initiation, quantum change has contributed more than continuous change in describing sexual initiation among young adolescents, suggesting the need for quantum change and chaotic models to advance behavioral prevention of HIV/AIDS.

    This paper discusses the application of a method based on human subjective preference to the acoustic design of a Javanese gamelan performance hall. Some important distinctions between Javanese gamelan ensembles and Western classical orchestra are the tuning system, orchestral blending process, and technique of playing. The results of subjective preference test using the rank order method showed that the subjects preferred 24·25 ms for the initial time delay gap ( ITDG) and the smallest value of the inter-aural cross-correlation ( IACC). The preferred ITDG agree with the ITDG from the room response measured in a traditional pendopo in Indonesia, which is not a common concert hall but an open-sided hall. However, the preferred IACC is not in agreement with the measured ITDG in the pendopo .

    Sexual violence is highly prevalent in armed conflict and other humanitarian crises and attracting increasing policy and practice attention. This systematic review aimed to canvas the extent and impact of initiatives to reduce incidence, risk and harm from sexual violence in conflict, post-conflict and other humanitarian crises, in low and middle income countries. Twenty three bibliographic databases and 26 websites were searched, covering publications from 1990 to September 2011 using database-specific keywords for sexual violence and conflict or humanitarian crisis. The 40 included studies reported on seven strategy types: i) survivor care; ii) livelihood initiatives; iii) community mobilisation; iv) personnel initiatives; v) systems and security responses; vi) legal interventions and vii) multiple component interventions. Conducted in 26 countries, the majority of interventions were offered in African countries. Despite the extensive literature on sexual violence by combatants, most interventions addressed opportunistic forms of sexual violence committed in post-conflict settings. Only one study specifically addressed the disaster setting. Actual implementation of initiatives appeared to be limited as was the quality of outcome studies. No studies prospectively measured incidence of sexual violence, although three studies provided some evidence of reductions in association with firewood distribution to reduce women's exposure, as did one program to prevent sexual exploitation and abuse by peacekeeping forces. Apparent increases to risk resulted from lack of protection, stigma and retaliation associated with interventions. Multiple-component interventions and sensitive community engagement appeared to contribute to positive outcomes. Significant obstacles prevent women seeking help following sexual violence, pointing to the need to protect anonymity and preventive strategies. This review contributes a conceptual framework for understanding the forms, settings

    Prospective studies regarding the psychosexual impact after different types of breast reconstruction (BR) are scarce. The impact of either implant or deep inferior epigastric artery perforator (DIEP) flap BR on body image and sexual relationship satisfaction was investigated in time. At baseline, 98 women opting for delayed implant or DIEP flap BR after mastectomy for breast cancer completed a survey. The majority was followed up at 6 months (96%) and 20 months (86%) postoperatively. Questionnaires included the body image scale, Dutch Relationship Questionnaire, Short Form - 36 Health Survey and the Impact of Event Scale. Mixed modeling analyses indicated that preoperative body image improved significantly after 20 months (p body image was related to a better general mental health (p = 0.02), less cancer distress (p Body image and sexual relationship satisfaction significantly improved after BR, and this was not related to the BR type. Psychosexual consequences from previous cancer treatment may interfere. Lower general mental health, higher cancer distress, less partner relationship satisfaction or receiving hormonal therapy can negatively affect body image or sexual relationship satisfaction.

    2012-01-01

    Full Text Available This paper describes in a detailed manner a method to implement a simultaneous localization and mapping (SLAM system based on monocular vision for applications of visual odometry, appearance-based sensing, and emulation of range-bearing measurements. SLAM techniques are required to operate mobile robots in a priori unknown environments using only on-board sensors to simultaneously build a map of their surroundings; this map will be needed for the robot to track its position. In this context, the 6-DOF (degree of freedom monocular camera case (monocular SLAM possibly represents the harder variant of SLAM. In monocular SLAM, a single camera, which is freely moving through its environment, represents the sole sensory input to the system. The method proposed in this paper is based on a technique called delayed inverse-depth feature initialization, which is intended to initialize new visual features on the system. In this work, detailed formulation, extended discussions, and experiments with real data are presented in order to validate and to show the performance of the proposal.

    Full Text Available Enteral formula feeding is a risk factor for necrotizing enterocolitis (NEC in premature infants, yet studies are conflicting regarding the safest timing for introduction and advancement of feeds. Our aim was to test the effects of early vs. late initiation and abrupt vs. gradual advancement of enteral feeding of an intact vs. hydrolyzed protein formula on NEC incidence and severity in preterm pigs. In Experiment 1, preterm pigs received total parenteral nutrition (TPN at birth with abrupt initiation of enteral formula feeds (50% full intake on d of life (DOL 2 (EA or 5 (LA while PN continued. Pigs were also fed formula containing either intact or hydrolyzed protein. In Experiment 2, preterm pigs received TPN at birth with enteral, hydrolyzed-protein formula feeds introduced on DOL 2 either abruptly (EA; 50% full feeds or gradually (EG; 10-50% full feeds over 5 d while PN continued. NEC incidence and severity were assessed based on macroscopic and histological scoring. In Experiment 1, NEC incidence (41% vs. 70%, P<0.05 and severity were reduced in LA vs. EA groups and LA was associated with a higher survival rate, daily weight gain and jejunum villus height. Piglets fed hydrolyzed vs. intact protein formula had lower stomach content weights and similar NEC incidence. In Experiment 2, NEC incidence and severity were not different between pigs the EG vs. EA group. Proinflammatory gene expression (IL-1β, IL-6 and S100A9 in the ileum was lower in both LA and EG vs. EA groups. In conclusion, delayed initiation but not gradual advancement of enteral feeding is protective against NEC in preterm pigs. Feeding hydrolyzed vs. intact protein formula improved gastric transit without affecting the NEC incidence.

    2012-09-01

    Full Text Available Abstract Background Antiretroviral therapy (ART initiation in eligible HIV-infected pregnant women is an important intervention to promote maternal and child health. Increasing the duration of ART received before delivery plays a major role in preventing vertical HIV transmission, but pregnant women across Africa experience significant delays in starting ART, partly due the perceived need to deliver ART counseling and patient education before ART initiation. We examined whether delaying ART to provide pre-ART counseling was associated with improved outcomes among HIV-infected women in Cape Town, South Africa. Methods We undertook a retrospective cohort study of 490 HIV-infected pregnant women referred to initiate treatment at an urban ART clinic. At this clinic all patients including pregnant women are screened by a clinician and then undergo three sessions of counseling and patient education prior to starting treatment, commonly introducing delays of 2–4 weeks before ART initiation. Data on viral suppression and retention in care after ART initiation were taken from routine clinic records. Results A total of 382 women initiated ART before delivery (78%; ART initiation before delivery was associated with earlier gestational age at presentation to the ART service (p  Conclusions A substantial proportion of eligible pregnant women referred for ART do not begin treatment before delivery in this setting. Among women who do initiate ART, delaying initiation for patient preparation is not associated with improved maternal outcomes. Given the need to maximize the duration of ART before delivery for prevention of mother-to-child HIV transmission, there is an urgent need for new strategies to help expedite ART initiation in eligible pregnant women.

    Delay in initiation of tuberculosis (TB) treatment may have a tremendous impact on disease transmission, development of drug resistance, poor outcome and overall survival of TB patients. The delay can occur at various levels. Delay in initiation of treatment after diagnosis is mostly due to health system failure and has immense programmatic implications. It has not been studied extensively in the Indian setting. The authors did a cohort analysis of all TB patients initiated on treatment from two primary health centres (PHCs) at Ballabgarh Health and Demographic Surveillance System between January 2007 and December 2014. Diagnosis and treatment of TB in the study area was done as per the protocol envisaged in the national program. Information related to demography, details of diagnosis and treatment of TB and outcome of treatment were extracted from the TB register. Delay in initiation of treatment after diagnosis was considered if the gap between diagnosis and treatment was greater than 7 days. Bivariate and multivariate analyses were done to find the association of various factors with delay in initiation of treatment after diagnosis. Out of 885 patients, 662 patients started treatment for pulmonary TB. Mean time interval between diagnosis and initiation of treatment was 8.95 days. Only 57.7% of pulmonary TB patients were started on treatment within 7 days of diagnosis, and an additional 24.5% were started on treatment 8-14 days after diagnosis. Patients on retreatment regimens and those residing in villages without a PHC were more likely to have delayed initiation of treatment (odds ratio (OR)=1.82 (1.3-2.7, p=0.001) and OR=1.62 (1.1-2.5, p=0.01) respectively). Delay in initiation of treatment was also associated with unfavourable treatment outcome such as default, failure or death. There is a need to have healthcare changes related to TB care to enable initiation of treatment as early as possible. Pretreatment counselling especially for retreatment patients is

    Full Text Available Introduction: Whether early antiretroviral therapy (ART initiation could impact sexual risk behaviours remains to be documented. We aimed to investigate changes in sexual behaviours within the 24 months following an early versus standard ART initiation in HIV-positive adults with high CD4 counts. Methods: We used data from a prospective behavioural study nested in a randomized controlled trial of early ART (Temprano-ANRS12136. Time trends in sexual behaviours from enrolment in the trial (M0 to 12-month (M12 and 24-month (M24 visits were measured and compared, using Generalized Estimating Equations models, between participants randomly assigned either to initiate ART immediately (early ART or to defer ART initiation until on-going WHO starting criteria are met (standard ART. Indicators of sexual behaviours included 1 sexual activity in the past year, 2 multiple partnership in the past year, 3 unprotected sex at last intercourse and 4 risky sex (i.e. unprotected sex with a partner of HIV negative/unknown status at last intercourse. Results: Analyses included 1952 participants (975 with early ART and 977 with standard ART; overall median baseline CD4 count: 469/mm3. Among participants with early ART, significant decreases were found between M0 and M24 in sexual activity (Odds Ratio [OR] 0.72, 95% Confidence Interval [95% CI] 0.57–0.92, multiple partnership (OR 0.57, 95% CI 0.41–0.79, unprotected sex (OR 0.59, 95% CI 0.47–0.75 and risky sex (OR 0.58, 95% CI 0.45–0.76. Among participants with standard ART, sexual behaviours showed similar trends over time. These decreases mostly occurred within the 12 months following enrolment in the trial in both groups and prior to ART initiation in participants with standard ART. For unprotected sex and risky sex, decreases were or tended to be more pronounced among patients reporting that their last sexual partner was non-cohabiting. Conclusions: In these sub-Saharan adults with high CD4 counts, entry

    Data from the national Teen Health and Technology Study of adolescents 13-18 years old (N = 5091) were used to examine online formation of romantic relationships. Results show that lesbian, gay, bisexual, transgender, and queer (LGBTQ) and non-LGBTQ adolescents similarly were most likely to have met their most recent boy/girlfriend in the past 12 months at school. However, they differed on many characteristics of romantic relationship initiation, including the extent to which they initiated romantic relationships online. LGBTQ and non-LGBTQ adolescents also differed on level of offline access to potential partners, offline popularity, and numerous other factors possibly related to online relationship initiation (e.g., Internet use and demographic factors). Even after adjusting for differences in these factors, LGBTQ adolescents were more likely than non-LGBTQ adolescents to find boy/girlfriends online in the past 12 months. The results support the rich-get-richer hypothesis as well as the social compensation hypothesis.

  7. Sexuality and sex education at home and school.

    1999-06-01

    This article reviews numerous studies of parent-adolescent communication about sexuality and 30 studies of sexuality and HIV education programs. Although parent-adolescent communication about sexuality has increased during the last few decades, both the occurrence and the quality of this communication could still be greatly improved. There does not exist a clear simple relationship between greater parent-adolescent communication and less adolescent risk-taking behavior, but both adults and youth believe it is important anyway. Sexuality and HIV education programs do not increase any measure of sexual activity, but some of them with ten common characteristics do reduce sexual risk-taking, either by delaying or reducing sexual behavior or increasing condom use. Thus, these programs can be an effective component in a larger initiative to reduce HIV, other STDs, and unplanned pregnancy in adolescence.

  8. The socio-political context of migration and reproductive health disparities: The case of early sexual initiation among Mexican-origin immigrant young women.

    Prior research often explains the lower risk of early sexual initiation among foreign-born Mexican-origin young women by a patriarchal and sexually conservative "traditional Latino culture." This definition overlooks structural factors such as exploitation of migrant workers, and conflates gender inequality and sexual expectations. I use an intersectional framework and the theory of gender and power to explore how gender inequality and sexual expectations are both influenced by structural factors and affect reproductive health outcomes. I integrate data from qualitative interviews with 21 first and second generation Mexican-origin women in 2013-2014 with data from discrete time hazard models with 798 Mexican-origin young women in the National Longitudinal Study of Adolescent to Adult Health. Qualitative results demonstrate that gender inequality and sexual expectations in Mexican-origin immigrant households are associated with structural factors. Gender inequality occurs more often in households with family instability, greater poverty, and among parents who migrated independently. Qualitative data also demonstrate that parental gendered expectations are sometimes at odds to what parents are actually doing in the household. Finally, contrary to assumptions that a patriarchal "traditional Latino culture" protects against early sexual initiation, qualitative and multivariate quantitative data suggest that household gender inequality increases risk of early sexual initiation. These findings challenge the utility of a culturalist approach that views culture as determining health behavior among immigrants and demonstrate the need to incorporate an intersectional framework that includes structural factors. This approach may reduce stereotypes and identify meaningful interventions to reduce reproductive health disparities. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Early initiation of sexual intercourse has been associated with negative consequences, such as higher rates of unwanted pregnancy and HIV infection. This study examined the attitudes and behavior of rural Thai adolescent students aged 16 to 20 years from northern Thailand regarding sexual intercourse. Differences between participants who previously had sexual intercourse and those who had not were explored. Those who had not previously had sexual intercourse were asked about the reasons why they had not had sex, their future plans for having sex and their dating experiences. More than 70% of participants stated they had not previously had sexual intercourse but one third of this group reported engaging in other sexual behavior. There were significant differences by gender, religion, ethnicity, and household income between those who had previously had sex and those who had not. Among those who had not previously had sexual intercourse, concern for their parents' feelings was the most common reason for delaying intercourse. About two-thirds of this group had plans not to have sexual intercourse until after marriage; nearly half of them reported currently having a boyfriend/girlfriend. Interventions aimed at delaying sexual intercourse should involve adolescents in their design and include their attitudes for delaying intercourse. Because of many gender differences seen in our study, interventions should be designed differently for males and females in rural northern Thailand.

    Previously, it was reported that the most preferred initial time delay gap [Δt1]pand subsequent reverberation time are described by the minimum value of the effective duration (τe)minof the running autocorrelation function (ACF) of music signals (2 T=2·0 s) (Y. ANDO et al. 1989 Journal of Acoustical Society of America86, 644-649). This paper shows whether this result is supported or not by use of the electro-physiological method. Experiments were performed for sound fields changing the initial time delay gapΔt1 of a single reflection with vocal music as a source signal, which has large changes in runningτe . The results at the time interval when (τe)minof the music is observed reveal that the scale value of subjective preference is closely related to the value of τeof the alpha wave obtained from the left heimsphere.

    Uncertainty remains about effectiveness of continuous glucose monitoring (CGM) in pediatric type 1 diabetes (T1D). Success with CGM is related to CGM adherence, which may relate to readiness to make the behavior changes required for effective use. We hypothesize that readiness for change will be greater at initiation of insulin pump therapy than in established pump users, and that this will predict CGM adherence. Our objective was to evaluate the feasibility of a randomized controlled trial (RCT) in children with established T1D comparing simultaneous pump and CGM initiation to standard pump therapy with delayed CGM initiation. We randomized participants to simultaneous pump and CGM initiation or to standard pump therapy with the option of adding CGM 4 months later. CGM adherence was tracked via web-based download and readiness for change assessed with the SOCRATES questionnaire. Of 41 eligible children, 20 agreed to participate; 15 subjects completed the study (7 males; baseline age 11.8 ± 4.0 years; T1D duration 2.7 ± 2.7 years; mean A1C 8.2 ± 0.8%). Six of 8 simultaneous group subjects used CGM > 60% of the time for 4 months compared to 1 of 7 delayed group subjects (P = .02). Using SOCRATES, we could assign 87-100% of subjects to a single motivation stage at baseline and 4 months. This pilot study demonstrates the feasibility of randomizing pump naïve children and adolescents with established T1D to simultaneous pump and CGM initiation versus standard pump therapy with delayed CGM initiation. Lessons from this pilot study were used to inform development of a full-scale multicenter RCT. © 2014 Diabetes Technology Society.

    Background: Ongoing research is focusing on the identification of those individuals with mild cognitive impairment (MCI) who are most likely to convert to Alzheimer's disease (AD). We investigated whether recognition memory tasks in combination with delayed recall measure of episodic memory and CSF biomarkers can predict MCI to AD conversion at 24-month follow-up. Methods: A total of 397 amnestic-MCI subjects from Alzheimer's disease Neuroimaging Initiative were included. Logistic regression modeling was done to assess the predictive value of all RAVLT measures, risk factors such as age, sex, education, APOE genotype, and CSF biomarkers for progression to AD. Estimating adjusted odds ratios was used to determine which variables would produce an optimal predictive model, and whether adding tests of interaction between the RAVLT Delayed Recall and recognition measures (traditional score and d-prime) would improve prediction of the conversion from a-MCI to AD. Results: 112 (28.2%) subjects developed dementia and 285 (71.8%) subjects did not. Of the all included variables, CSF Aβ1-42 levels, RAVLT Delayed Recall, and the combination of RAVLT Delayed Recall and d-prime were predictive of progression to AD (χ2 = 38.23, df = 14, p < 0.001). Conclusions: The combination of RAVLT Delayed Recall and d-prime measures may be predictor of conversion from MCI to AD in the ADNI cohort, especially in combination with amyloid biomarkers. A predictive model to help identify individuals at-risk for dementia should include not only traditional episodic memory measures (delayed recall or recognition), but also additional variables (d-prime) that allow the homogenization of the assessment procedures in the diagnosis of MCI.

    A randomized, blinded, multicenter, controlled study was undertaken to assess the impact of a multiyear continuing medical education (CME) initiative on physician knowledge and behavior in the treatment of erectile dysfunction (ED). The objective of this study was to assess the efficacy of CME and compare applied knowledge and attitude scores of participants in the Consortium for Improvement in Erectile Function (CIEF), to non-CIEF participants. Subjects were selected randomly and contacted anonymously, by mail, email and fax and requested to enroll in this study. A blinded, validated questionnaire and series of standardized patient (SP) case studies and attitude questions were given to CIEF participants, defined as those who showed an interest in learning more about ED and who took at least one CME-certified program on ED from the CIEF website and non-CIEF participants, defined as those who showed interest in learning more about ED and who took at least one CME-certified program on ED from any organization other than CIEF. The primary outcome was a comparison of subjects' scores who participated in at least one CIEF program to non-participants in CIEF programs. Subjects were also compared based on SP case scores, attitude scores, specialty, years in practice, age and gender. Answers were ranked from best to worst and assigned a corresponding value of 10...3, 2, 1 and 0 (10 being the best), assuming that there may be more than one correct answer to each question in clinical practice. SAS version 9.1 analysis of variance model was used by an independent consultant. A total of 120 physicians completed the questionnaire: 87 urologists (UROs) and 33 primary care physicians (PCPs). UROs scored higher on SP cases compared with PCPs (P=0.0039); however, as a result of participating in CIEF programs, PCPs trended toward more comparable scores to UROs; P=0.23 for SP case 2 that was clinically less complex and P=0.19 for SP case 3 that was more complex.

    Some guidelines recommend an early voiding cystourethrography (VCUG) after endoscopic treatment of vesicoureteral reflux (VUR), but there's no consensus if it's necessary a long-term follow-up in these patients. The aim of our study is analyze if it's necessary a delayed VCUG after initial successful treatment with Dx/HA. We have reviewed all medical charts of patients that underwent Dx/HA treatment from 2006 to 2010. We have selected patients with initial successful treatment and more than 3 years of radiological and clinical follow-up. We have analyzed late clinical and radiological outcomes. One hundred and sixty children with 228 refluxing ureters underwent Dx/HA endoscopic treatment with a mean follow-up of 52.13 months. Early VCUG was performed in 215 ureters with an initial successful rate of 84.1%. The group of study was 94/215 ureters with more than 3 years of follow-up with a delayed VCUG. VUR was still resolved in 79,8% of the ureters. Clinical success rate was 91.7%. The incidence of febrile urinary tract infection in those patients with cured VUR and those with a relapsed VUR was 8 and 15%, respectively; but there were no significant differences. We have not found any variable related with relapsed VUR except those ureters that initially received 2 injections (P<.05). If our objective in the treatment of VUR is to reduce the incidence of febrile urinary tract infection it is not necessary to perform a delayed VCUG even though the long-term radiological outcomes is worse than clinical outcome.

    The problem of forecasting the behavior of a complex dynamical system through analysis of observational time-series data becomes difficult when the system expresses chaotic behavior and the measurements are sparse, in both space and/or time. Despite the fact that this situation is quite typical across many fields, including numerical weather prediction, the issue of whether the available observations are "sufficient" for generating successful forecasts is still not well understood. An analysis by Whartenby et al. (2013) found that in the context of the nonlinear shallow water equations on a β plane, standard nudging techniques require observing approximately 70 % of the full set of state variables. Here we examine the same system using a method introduced by Rey et al. (2014a), which generalizes standard nudging methods to utilize time delayed measurements. We show that in certain circumstances, it provides a sizable reduction in the number of observations required to construct accurate estimates and high-quality predictions. In particular, we find that this estimate of 70 % can be reduced to about 33 % using time delays, and even further if Lagrangian drifter locations are also used as measurements.

    Achieving the combination of delayed and immediate release of a vaccine from a delivery device without applying external triggers remains elusive in implementing single administration vaccination strategies. Here a means of vaccine delivery is presented, which exploits osmosis to trigger delayed burst release of an active compound. Poly(ε-caprolactone) capsules of 2 mm diameter were prepared by dip-coating, and their burst pressure and release characteristics were evaluated. Burst pressures (in bar) increased with wall thickness (t in mm) following Pburst  = 131(.) t + 3(.) 4 (R(2)  = 0.93). Upon immersion in PBS, glucose solution-filled capsules burst after 8.7 ± 2.9 days. Copolymers of hydrophobic ε -caprolactone and hydrophilic polyethylene glycol were synthesized and their physico-chemical properties were assessed. With increasing hydrophilic content, the copolymer capsules showed increased water uptake rates and maximum weight increase, while the burst release was earlier: 5.6 ± 2.0 days and 1.9 ± 0.2 days for 5 and 10 wt% polyethylene glycol, respectively. The presented approach enables the reproducible preparation of capsules with high versatility in materials and properties, while these vaccine delivery vehicles can be prepared separately from, and independently of the active compound.

    Randomized controlled trials have supported integrated oncology and palliative care (PC); however, optimal timing has not been evaluated. We investigated the effect of early versus delayed PC on quality of life (QOL), symptom impact, mood, 1-year survival, and resource use. Between October 2010 and March 2013, 207 patients with advanced cancer at a National Cancer Institute cancer center, a Veterans Affairs Medical Center, and community outreach clinics were randomly assigned to receive an in-person PC consultation, structured PC telehealth nurse coaching sessions (once per week for six sessions), and monthly follow-up either early after enrollment or 3 months later. Outcomes were QOL, symptom impact, mood, 1-year survival, and resource use (hospital/intensive care unit days, emergency room visits, chemotherapy in last 14 days, and death location). Overall patient-reported outcomes were not statistically significant after enrollment (QOL, P = .34; symptom impact, P = .09; mood, P = .33) or before death (QOL, P = .73; symptom impact, P = .30; mood, P = .82). Kaplan-Meier 1-year survival rates were 63% in the early group and 48% in the delayed group (difference, 15%; P = .038). Relative rates of early to delayed decedents' resource use were similar for hospital days (0.73; 95% CI, 0.41 to 1.27; P = .26), intensive care unit days (0.68; 95% CI, 0.23 to 2.02; P = .49), emergency room visits (0.73; 95% CI, 0.45 to 1.19; P = .21), chemotherapy in last 14 days (1.57; 95% CI, 0.37 to 6.7; P = .27), and home death (27 [54%] v 28 [47%]; P = .60). Early-entry participants' patient-reported outcomes and resource use were not statistically different; however, their survival 1-year after enrollment was improved compared with those who began 3 months later. Understanding the complex mechanisms whereby PC may improve survival remains an important research priority. © 2015 by American Society of Clinical Oncology.

    Full Text Available Abstract Background There has been substantial increase in use of androgen deprivation therapy as adjuvant management of prostate cancer. However, this leads to a range of musculoskeletal toxicities including reduced bone mass and increased skeletal fractures compounded with rapid metabolic alterations, including increased body fat, reduced lean mass, insulin resistance and negative lipoprotein profile, increased incidence of cardiovascular and metabolic morbidity, greater distress and reduced quality of life. Numerous research studies have demonstrated certain exercise prescriptions to be effective at preventing or even reversing these treatment toxicities. However, all interventions to date have been of rehabilitative intent being implemented after a minimum of 3 months since initiation of androgen deprivation, by which time considerable physical and psychological health problems have manifested. The pressing question is whether it is more efficacious to commence exercise therapy at the same time as initiating androgen deprivation, so treatment induced adverse effects can be immediately attenuated or indeed prevented. Methods/design We are proposing a multi-site randomized controlled trial with partial crossover to examine the effects of timing of exercise implementation (immediate or delayed on preserving long-term skeletal health, reversing short- and long-term metabolic and cardiovascular risk factors, and supporting mental health in men receiving androgen deprivation therapy. 124 men who are about to initiate androgen deprivation for prostate cancer will be randomized to immediate or delayed groups. Immediate will commence a 6-month exercise program within 7–10 days of their first dose. Delayed will receive usual care for 6 months and then commence the exercise program for 6 months (partial cross-over. Immediate will be free to adopt the lifestyle of their choosing following the initial 6-month intervention. Measurements for primary and

    It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

    Provider-initiated HIV testing and counseling (PITC) has rapidly expanded in many countries including Uganda. However, because it provides HIV prevention information without individualized risk assessment and risk reduction counseling it may create missed opportunities for effective HIV prevention counseling. Our objective was to assess the effect of a brief motivational interviewing-based intervention during outpatient PITC in rural Uganda compared to Uganda's standard-of-care PITC at reducing HIV transmission-relevant sexual risk behavior. We enrolled 333 (160 control, 173 intervention) participants in a historical control trial to test the intervention vs. standard-of-care. Participants received PITC and standard-of-care or the intervention counseling and we assessed sexual risk behavior at baseline and 3 and 6 months follow-up. The intervention condition showed 1.5-2.4 times greater decreases in high risk sexual behavior over time compared to standard-of-care (p = 0.015 and p = 0.004). These data suggest that motivational interviewing based counseling during PITC may be a promising intervention to reduce high-risk sexual behavior and potentially reduce risk of HIV infection.

    2007-12-01

    This paper examines timing of puberty and mechanisms through which society prepares adolescents to understand and deal with it in Malawi. Data from a national representative survey of adolescents and in-depth interviews also conducted with adolescents are used. SPSS was used to analyse survey data while N6 was used to analyse qualitative data. Results show that the onset of menarche in girls and various pubertal body changes in boys can be a cause of joy, excitement, or distress depending on how adolescents understand what this means to them at this critical stage when they start defining and comprehending their sexuality. Much more emphasis is put on educating girls about reproductive implications of menarche than on what is expected of boys as sexual beings, which may contribute to boys' greater indulgence in risky sexual behaviors than girls. The significance of initiation ceremonies in some communities provides an important platform through which programs can reach many adolescents and intervene, particularly in addressing the widely held notion among initiates that attending these ceremonies symbolizes that one is not a child anymore and can have sex.

    Lesbians and bisexual women are at risk for human papillomavirus (HPV) infection from female and male sexual partners. To examine the association between sexual orientation identity and HPV vaccination among U.S. women and girls. Cross-sectional, using 2006-2010 National Survey of Family Growth data. U.S. civilian noninstitutionalized population. The 2006-2010 National Survey of Family Growth used stratified cluster sampling to establish a national probability sample of 12,279 U.S. women and girls aged 15 to 44 years. Analyses were restricted to 3253 women and girls aged 15 to 25 years who were asked about HPV vaccination. Multivariable logistic regression was used to obtain prevalence estimates of HPV vaccine awareness and initiation adjusted for sociodemographic and health care factors for each sexual orientation identity group. Among U.S. women and girls aged 15 to 25 years, 84.4% reported having heard of the HPV vaccine; of these, 28.5% had initiated HPV vaccination. The adjusted prevalence of vaccine awareness was similar among heterosexual, bisexual, and lesbian respondents. After adjustment for covariates, 8.5% (P = 0.007) of lesbians and 33.2% (P = 0.33) of bisexual women and girls who had heard of the vaccine had initiated vaccination compared with 28.4% of their heterosexual counterparts. Self-reported, cross-sectional data, and findings may not be generalizable to periods after 2006 to 2010 or all U.S. lesbians aged 15 to 25 years (because of the small sample size for this group). Adolescent and young adult lesbians may be less likely to initiate HPV vaccination than their heterosexual counterparts. Programs should facilitate access to HPV vaccination services among young lesbians. National Cancer Institute.

    Full Text Available Studies from Sub-Saharan Africa have shown that a substantial number of HIV patients eligible for antiretroviral therapy (ART do not start treatment. However, data from other low- or middle-income countries are scarce. In this study, we describe the outcomes of 4105 HIV patients who became ART eligible from January 2007 to November 2011 in an HIV cohort study in India. After three years of ART eligibility, 78.4% started ART, 9.3% died before ART initiation, and 10.3% were lost to followup. Diagnosis of tuberculosis, being homeless, lower CD4 count, longer duration of pre-ART care, belonging to a disadvantaged community, being widowed, and not living near a town were associated with delayed ART initiation. Diagnosis of tuberculosis, being homeless, lower CD4 count, shorter duration of pre-ART care, belonging to a disadvantaged community, illiteracy, and age >45 years were associated with mortality. Being homeless, being single, not living near a town, having a CD4 count <150 cells/μL, and shorter duration of pre-ART care were associated with loss to followup. These results highlight the need to improve the timely initiation of ART in HIV programmes in India, especially in ART eligible patients with tuberculosis, low CD4 counts, living in rural areas, or having a low socioeconomic status.

    This study aimed to investigate patients' willingness to initiate a preventive treatment and compared two established effect measures to the newly developed Delay of Events (DoE) measure that expresses treatment effect as a gain in event-free time. In this cross-sectional, randomized survey experiment in the general Swedish population,1079 respondents (response rate 60.9%) were asked to consider a preventive cardiovascular treatment. Respondents were randomly allocated to one of three effect descriptions: DoE, relative risk reduction (RRR), or absolute risk reduction (ARR). Univariate and multivariate analyses were performed investigating willingness to initiate treatment, views on treatment benefit, motivation and importance to adhere and willingness to pay for treatment. Eighty-one percent were willing to take the medication when the effect was described as DoE, 83.0% when it was described as RRR and 62.8% when it was described as ARR. DoE and RRR was further associated with positive views on treatment benefit, motivation, importance to adhere and WTP. Presenting treatment effect as DoE or RRR was associated with a high willingness to initiate treatment. An approach based on the novel time-based measure DoE may be of value in clinical communication and shared decision making. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd..

    ATF4 is a pro-oncogenic transcription factor whose translation is activated by eIF2 phosphorylation through delayed re-initiation involving two uORFs in the mRNA leader. However, in yeast, the effect of eIF2 phosphorylation can be mimicked by eIF5 overexpression, which turns eIF5 into translational inhibitor, thereby promoting translation of GCN4, the yeast ATF4 equivalent. Furthermore, regulatory protein termed eIF5-mimic protein (5MP) can bind eIF2 and inhibit general translation. Here, we show that 5MP1 overexpression in human cells leads to strong formation of 5MP1:eIF2 complex, nearly comparable to that of eIF5:eIF2 complex produced by eIF5 overexpression. Overexpression of eIF5, 5MP1 and 5MP2, the second human paralog, promotes ATF4 expression in certain types of human cells including fibrosarcoma. 5MP overexpression also induces ATF4 expression in Drosophila. The knockdown of 5MP1 in fibrosarcoma attenuates ATF4 expression and its tumor formation on nude mice. Since 5MP2 is overproduced in salivary mucoepidermoid carcinoma, we propose that overexpression of eIF5 and 5MP induces translation of ATF4 and potentially other genes with uORFs in their mRNA leaders through delayed re-initiation, thereby enhancing the survival of normal and cancer cells under stress conditions.

    Purpose This study examined the association between early initiation of problem behaviors (alcohol drinking, cigarette smoking, and sexual intercourse) and suicidal behaviors (suicidal ideation and suicide attempts), and explored the effect of concurrent participation in these problem behaviors on suicidal behaviors among Korean adolescent males and females. Materials and Methods Data were obtained from the 2006 Korean Youth Risk Behavior Survey, a nationally representative sample of middle and high school students (32,417 males and 31,467 females) in grades seven through twelve. Bivariate and multivariate logistic analyses were conducted. Several important covariates, such as age, family living structure, household economic status, academic performance, current alcohol drinking, current cigarette smoking, current butane gas or glue sniffing, perceived body weight, unhealthy weight control behaviors, subjective sleep evaluation, and depressed mood were included in the analyses. Results Both male and female preteen initiators of each problem behavior were at greater risk for suicidal behaviors than non-initiators, even after controlling for covariates. More numerous concurrent problematic behaviors were correlated with greater likelihood of seriously considering or attempting suicide among both males and females. This pattern was more clearly observed in preteen than in teen initiators although the former and latter were engaged in the same frequency of problem behavior. Conclusion Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse, particularly among preteens, represented an important predictor of later suicidal ideation and suicide attempts in both genders. Thus, early preventive intervention programs should be developed and may reduce the potential risks for subsequent suicidal behaviors. PMID:20046509

    Youth with confirmed histories of sexual abuse (N = 118) were followed longitudinally to examine associations between their initial sexual reactions to abuse and subsequent sexual functioning. Participants were interviewed at abuse discovery (ages 8 through 15) and again 1 and 6 years later. Eroticism and sexual anxiety emerged as distinct indices of abuse-specific sexual reactions and predicted subsequent sexual functioning. Eroticism was associated with indicators of heightened sexuality, including more sexual risk behavior and views of sexual intimacy focused on partners' needs. Sexual anxiety was associated with indicators of diminished sexuality, including few sexual partners and avoidant views of sexual intimacy. Age at abuse discovery moderated some associations, suggesting that the timing of abuse-specific reactions affects trajectories of sexual development. Findings point to the need for a developmental approach to understanding how abuse-specific sexual reactions disrupt sexual development and the need for early interventions promoting healthy sexual development.

    Mutations resulting in constitutive activation of signaling pathways that regulate ribosome biogenesis are among the most common genetic events in acute myeloid leukemia (AML). However, whether ribosome biogenesis presents as a therapeutic target to treat AML remains unexplored. Perturbations in ribosome biogenesis trigger the 5S ribonucleoprotein particle (RNP)-Mdm2-p53 ribosomal stress pathway, and induction of this pathway has been shown to have therapeutic efficacy in Myc-driven lymphoma. In the current study we address the physiological and therapeutic role of the 5S RNP-Mdm2-p53 pathway in AML. By utilizing mice that have defective ribosome biogenesis due to downregulation of ribosomal protein S19 (Rps19), we demonstrate that induction of the 5S RNP-Mdm2-p53 pathway significantly delays the initiation of AML. However, even a severe Rps19 deficiency that normally results in acute bone marrow failure has no consistent efficacy on already established disease. Finally, by using mice that harbor a mutation in the Mdm2 gene disrupting its binding to 5S RNP, we show that loss of the 5S RNP-Mdm2-p53 pathway is dispensable for development of AML. Our study suggests that induction of the 5S RNP-Mdm2-p53 ribosomal stress pathway holds limited potential as a single-agent therapy in the treatment of AML.

    noviembre de 2009. Se han revelado cosas en común entre el comportamiento sexual y cultural permitiendo visualizar el poder ejercido por los sistemas de representación social. Es importante poner en punto sobre la necesidad de mirar meticulosamente sobre el asunto, pues son emergentes en los varios escenarios del existir humano.Sexuality as a phenomenon that provides unique moments for people discover each other, it means oneself and another, allowing the realization of permeated practices by acquired symbolizations in adolescence. Being influenced by genetic, social and cultural rights factors, adolescent sexual behavior is often permeated by conflict situations. This study aimed to disclose sexual behaviors of Nursing University female students from Federal University of Piauí, as well as their mechanisms of influence and understanding the aspect that surrounds sexual initiation, considering the obstacles caused by the traditional training and modernizing aspirations. We adopted an ethnography method, by applying profound interviews with twelve students in the months of October and November, 2009. Interviews stood out intersection between sexual behavior and culture, allowing you to see the power exercised by the systems of social representation. It is important to emphasize the need for more importance and attention to the subject for being emergent in several scenes of human existence.

  18. Trading Later Rewards for Current Pleasure: Pornography Consumption and Delay Discounting.

    Internet pornography is a multi-billion-dollar industry that has grown increasingly accessible. Delay discounting involves devaluing larger, later rewards in favor of smaller, more immediate rewards. The constant novelty and primacy of sexual stimuli as particularly strong natural rewards make Internet pornography a unique activator of the brain's reward system, thereby having implications for decision-making processes. Based on theoretical studies of evolutionary psychology and neuroeconomics, two studies tested the hypothesis that consuming Internet pornography would relate to higher rates of delay discounting. Study 1 used a longitudinal design. Participants completed a pornography use questionnaire and a delay discounting task at Time 1 and then again four weeks later. Participants reporting higher initial pornography use demonstrated a higher delay discounting rate at Time 2, controlling for initial delay discounting. Study 2 tested for causality with an experimental design. Participants were randomly assigned to abstain from either their favorite food or pornography for three weeks. Participants who abstained from pornography use demonstrated lower delay discounting than participants who abstained from their favorite food. The finding suggests that Internet pornography is a sexual reward that contributes to delay discounting differently than other natural rewards. Theoretical and clinical implications of these studies are highlighted.

  19. Lack of sexual dimorphism in femora of the eusocial and hypogonadic naked mole-rat: a novel animal model for the study of delayed puberty on the skeletal system.

    Sex steroid hormones are major determinants of bone morphology and quality and are responsible for sexually dimorphic skeletal traits. Hypogonadism results in suboptimal skeletal development and may lead to an increased risk of bone fracture later in life. The etiology of delayed puberty and/or hypothalamic amenorrhea is poorly understood, and experimental animal models addressing this issue are predominantly based upon short-term experimental induction of hormonal suppression via gonadotropin releasing hormone antagonists (GnRH-a). This acute change in hormone profile does not necessarily emulate the natural progression of hypogonadic bone disorders. We propose a novel animal model with which to explore the effects of chronic hypogonadism on bone quality, the naked mole-rat (NMR; Heterocephalus glaber). This mouse-size rodent may remain reproductively suppressed throughout its life, if it remains as a subordinate within the eusocial mole-rat colony. NMRs live in large colonies with a single dominant breeding female. She, primarily by using aggressive social contact, naturally suppresses the hypothalamic gonadotropic axis of subordinate NMRs and thereby their reproductive expression. However, should an NMR be separated from the dominant breeder, within less than a week reproductive hormones may become elevated and the animal attains breeding status. We questioned if sexual suppression of subordinates impact upon the development and maintenance of the femora and lead to a sexually indistinct monomorphic skeleton. Femora were obtained from male and female NMRs that were either non-breeders (subordinate) or breeders at the time of sacrifice. Diaphyseal cross-sectional morphology, metaphyseal trabecular micro-architecture and tissue mineral density of the femur were measured using microcomputed tomography and diaphyseal mechanical properties were assessed by four-point bending tests to failure. Subordinates were sexually monomorphic and showed no significant

    Objective: Childhood sexual abuse (CSA) is associated with elevated risk of early marijuana use and cannabis use disorder (CUD). Both the prevalence of CSA and the course of marijuana use differ between African Americans and European Americans. The current study aimed to determine whether these differences manifest in racial/ ethnic distinctions in the association of CSA with early and problem use of marijuana. Method: Data were derived from female participants in a female twin study and a high-risk family study of substance use (n = 4,193, 21% African-American). Cox proportional hazard regression analyses using CSA to predict initiation of marijuana use and progression to CUD symptom(s) were conducted separately by race/ethnicity. Sibling status on the marijuana outcome was used to adjust for familial influences. Results: CSA was associated with both stages of marijuana use in African-American and European-American women. The association was consistent over the risk period (hazard ratio [HR] = 1.57, 95% confidence interval [CI] [1.37, 1.79] for initiation; HR = 1.51, 95% CI [1.21, 1.88] for CUD symptom onset) in European-American women. In African-American women, the HRs for initiation were 2.52 (95% CI [1.52, 4.18]) before age 15, 1.82 (95% CI [1.36, 2.44]) at ages 15–17, and nonsignificant after age 17. In the CUD symptom model, CSA predicted onset only at age 21 and older (HR = 2.17, 95% CI [1.31, 3.59]). Conclusions: The association of CSA with initiation of marijuana use and progression to problem use is stable over time in European-American women, but in African-American women, it varies by developmental period. Findings suggest the importance of considering race/ethnicity in prevention efforts with this high-risk population. PMID:26098032

    African-American males ages 13 through 24 are disproportionately affected by sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), accounting for over half of all HIV infections in this age group in the United States. Clear communication between African-American parents and their youth about sexual health is associated with higher rates of sexual abstinence, condom use, and intent to delay initiation of sexual intercourse. However, little is known about African-American fathers' perceptions of what facilitates and inhibits sexual health communication with their preadolescent and adolescent sons. We conducted focus groups with 29 African-American fathers of sons ages 10-15 to explore perceived facilitators and barriers for father-son communication about sexual health. Participants were recruited from barbershops in metropolitan and rural North Carolina communities highly affected by STIs and HIV, and data were analyzed using content analysis. Three factors facilitated father-son communication: (a) fathers' acceptance of their roles and responsibilities; (b) a positive father-son relationship; and (c) fathers' ability to speak directly to their sons about sex. We also identified three barriers: (a) fathers' difficulty in initiating sexual health discussions with their sons; (b) sons' developmental readiness for sexual health information; and (c) fathers' lack of experience in talking with their own fathers about sex. These findings have implications for father-focused prevention interventions aimed at reducing risky sexual behaviors in adolescent African-American males. © 2017 Wiley Periodicals, Inc.

    Full Text Available Background. Despite the improvement in patient-physician communication techniques, sexuality and sexual health continue to be challenging areas for discussion during a clinical encounter. Most people are not prepared to discuss sexual matters openly as it can be perceived as negative or inappropriate. Consequently, an incomplete health assessment can result in delayed diagnosis or misdiagnosis. Case Report. We present a 33-year-old woman who developed recurrent left breast abscesses. She required multiple incision and drainage procedures in the operating room followed by antimicrobial therapy. Although she always had an initial improvement with this approach, she continued to have recurrences and development of new abscesses in other body areas. The polymicrobial nature of her recurrences prompted an extensive and costly workup to determine the nature of her condition. The cause was finally elucidated when a thorough sexual history was obtained. Poor hygiene practices during her sexual encounters were considered the cause of her recurrent abscesses. After medical therapy and modification of her sexual practices, she has not developed new recurrences for more than two years. Conclusion. Discussions on sexuality and sexual health are important parts of any clinical encounter, yet frequently forgotten or avoided. Becoming aware of their importance would avoid delayed diagnosis or misdiagnosis.

    Full Text Available Abstract Background In sub-Saharan Africa (SSA there are strong arguments for the provision of integrated sexual and reproductive health (SRH and HIV services. Most HIV transmissions are sexually transmitted or associated with pregnancy, childbirth, and breastfeeding. Many of the behaviours that prevent HIV transmission also prevent sexually transmitted infections and unintended pregnancies. There is potential for integration to increase the coverage of HIV services, as individuals who use SRH services can benefit from HIV services and vice-versa, as well as increase cost-savings. However, there is a dearth of empirical evidence on effective models for integrating HIV/SRH services. The need for robust evidence led a consortium of three organizations – International Planned Parenthood Federation, Population Council and the London School of Hygiene & Tropical Medicine – to design/implement the Integra Initiative. Integra seeks to generate rigorous evidence on the feasibility, effectiveness, cost and impact of different models for delivering integrated HIV/SRH services in high and medium HIV prevalence settings in SSA. Methods/design A quasi-experimental study will be conducted in government clinics in Kenya and Swaziland – assigned into intervention/comparison groups. Two models of service delivery are investigated: integrating HIV care/treatment into 1 family planning and 2 postnatal care. A full economic-costing will be used to assess the costs of different components of service provision, and the determinants of variations in unit costs across facilities/service models. Health facility assessments will be conducted at four time-periods to track changes in quality of care and utilization over time. A two-year cohort study of family planning/postnatal clients will assess the effect of integration on individual outcomes, including use of SRH services, HIV status (known/unknown and pregnancy (planned/unintended.

    To assess the 1-year continuation rates and new pregnancies following immediate versus delayed insertion of the levonorgestrel-releasing intrauterine system (LNG-IUS) after medical termination of pregnancy (MTOP) up to 20 weeks of gestation. A randomised controlled trial. Helsinki University Hospital, Finland, January 2013 to December 2014. A total of 267 women requesting MTOP and planning LNG-IUS for post-MTOP contraception. Insertion of LNG-IUS occurred immediately (0-3 days) or after a delay (2-4 weeks) following MTOP. Follow-up visits were at 3 months and 1 year after MTOP. LNG-IUS use at 1 year after MTOP. Women were randomised to immediate (n = 134) or delayed (n = 133) insertion of the LNG-IUS, and 133 and 131 were analysed; 127 (95.5%) women received immediate insertion and 111 (84.7%) women had delayed insertion of the LNG-IUS (risk ratio [RR] 1.13, 95% CI 1.04-1.22). The verified numbers of women continuing the LNG-IUS use at 1 year were 83 (62.4%) and 52 (39.7%) (RR 1.57, 95% CI 1.23-2.02). The numbers of new pregnancies were 6 (4.5%) and 16 (12.2%) (RR 0.37, 95% CI 0.15-0.91), and numbers of subsequent TOPs were 4 (3.0%) and 5 (3.8%) (RR 0.79, 95% CI 0.22-2.87). Immediate insertion of the LNG-IUS following MTOP resulted in higher 1-year continuation rates compared with delayed insertion. In addition, those receiving immediate insertion demonstrated a decreased new pregnancy rate, but no difference in the numbers of another TOP. Immediate LNG-IUS insertion after MTOP results in a higher 1-year continuation compared with delayed insertion. © 2017 Royal College of Obstetricians and Gynaecologists.

  6. An initial exploration of community mental health nurses' attitudes to and experience of sexuality-related issues in their work with people experiencing mental health problems.

    Human sexuality is a complex dynamic concept that escapes simple definition. Within nursing there seems to be a preference for broad holistic definitions that emphasize sexuality as an aspect of the unique human character. Whilst the nursing literature mostly portrays sexuality as wholesome and good, it also notes that sexuality can be a vehicle for the expression of power, hostility or hatred. In this study, the authors did not prescribe or limit the definition of 'sexuality'. Rather the term 'sexuality' was used in a broad sense in order to embrace the range of variables within the concept and allow respondents to consider the issues according to their own perspective. Despite broad acceptance of sexuality as a legitimate focus of health care, clinicians remain ambivalent about actively broaching sexual issues and there is a potential for clients' needs to go unmet. A number of intertwining variables can influence sexuality-related nursing practice. Nurses' attitudes are regarded as major barriers that prevent open discussion on the topic. This study aims to explore a sample of community mental health nurses' views on the topic of sexuality in relation to their work with clients. The authors adapted a sexual ideology scale previously used for the purposes of teaching students and promoting discussion. The questionnaire was distributed to nurse delegates at an annual CPNA conference. Two of the authors were available throughout the conference to discuss the study. Delegates were asked to recruit CMHN colleagues following the conference in order to increase the sample. The data are described and analysed using SPSS for Windows. Respondent characteristics have been cross-tabulated with item responses and analysed using chi-square and other statistical tests of association. The respondents (n = 122) confirmed sexuality as a relevant clinical issue and there was an overwhelming affirmation of people with mental health problems as sexual beings. Sixty-three per cent (n

    Although female sexual dysfunction is a problem with low priority, it can have a profound impact on quality of life. In women, the cycle of sexual response begins in the brain, where a memory, an image, a scent, music, or a fantasy acts as a trigger to prompt sexual arousal. Thus, the brain is really the key and starting place for treatment of sexual dysfunction. Decreased libido, altered arousal, inability to achieve orgasm, and dyspareunia are the four broad types of sexual dysfunction in women. Decreased libido, thought to be related to androgenic hormones, results in delayed or altered arousal, decreased vaginal lubrication and dilation, delayed or absent orgasm, and pain or dyspareunia, which can lead to an aversion to sexual experiences.

    This analysis aims to examine factors associated with delayed initiation and non-exclusive breastfeeding in Indonesia. Data were derived from the 2002/2003 and 2007 Indonesia Demographic and Health Survey. Information from 12,191 singleton live-born infants aged 0-23 months was used to examine factors associated with delayed initiation of breastfeeding. Furthermore, information from 3,187 singleton live-born infants aged 0-5 months was used to identify factors associated with non-exclusive breastfeeding. Associations between potential predictors and study outcomes were examined using logistic regression. Our study found that infants from high household wealth-index had significantly increased odds of both delayed initiation and non-exclusive breastfeeding. Other factors associated with an increased odds of delayed initiation of breastfeeding included infants from Sumatera region (OR=1.64, 95% CI: 1.38-1.95), Caesarean-section deliveries (OR=1.84, 95% CI: 1.39-2.44) and deliveries in government-owned (OR=1.38, 95% CI: 1.08-1.76) and non-health facility (OR=1.20, 95% CI: 1.00-1.43). Other factors associated with an increased odds for non-exclusive breastfeeding included parents who were in the workforce (OR=1.37, 95% CI: 1.06-1.78) and mothers with obstetric complication at childbirth (OR=1.35, 95% CI: 1.05-1.74). However, the odds reduced for infants from Eastern Indonesia (OR=0.64, 95% CI: 0.49-0.85). Poor breastfeeding practices are associated with environmental, socio-economic, pregnancy-birthing characteristics and maternal health services factors. Efforts to promote breastfeeding practices should be conducted comprehensively to target population at risk for poor breastfeeding practices.

    Understanding the role of socio-sexual cognitions and religiosity on adolescent sexual behavior could guide adolescent sexual health efforts. The present study utilized longitudinal data from 328 young women to assess the role of religion and socio-sexual cognitions on sexual behavior accrual (measuring both coital and non-coital sexual behavior). In the final triple conditional trajectory structural equation model, religiosity declined over time and then increased to baseline levels. Additionally, religiosity predicted decreased sexual conservatism and decreased sexual conservatism predicted increased sexual behavior. The final models are indicative of young women's increasing accrual of sexual experience, decreasing sexual conservatism and initial decreasing religiosity. The results of this study suggest that decreased religiosity affects the accrual of sexual experience through decreased sexual conservatism. Effective strategies of sexual health promotion should include an understanding of the complex role of socio-sexual attitudes with religiosity. PMID:24215966

    Delayed fission is a nuclear decay process that couples {beta} decay and fission. In the delayed fission process, a parent nucleus undergoes {beta} decay and thereby populates excited states in the daughter. If these states are of energies comparable to or greater than the fission barrier of the daughter, then fission may compete with other decay modes of the excited states in the daughter. In this paper, mechanism and some experiments of the delayed fission will be discussed. (author)

    To our knowledge, there is no well-articulated process for the design of culturally informed behavioral intervention technologies. This paper describes the early stages of such a process, illustrated by the methodology for the ongoing development of a behavioral intervention technology targeting generalized anxiety disorder and major depression among young sexual minority men. We integrated instructional design for Internet behavioral intervention technologies with greater detail on information sources that can identify user needs in understudied populations, as well as advances in the understanding of technology-specific behavioral intervention technology dimensions that may need to be culturally tailored. General psychological theory describing how to effect change in the clinical target is first integrated with theory describing potentially malleable factors that help explain the clinical problem within the population. Additional information sources are then used to (1) evaluate the theory, (2) identify population-specific factors that may affect users' ability to relate to and benefit from the behavioral intervention technology, and (3) establish specific skills, attitudes, knowledge, etc, required to change malleable factors posited in the theory. User needs result from synthesis of this information. Product requirements are then generated through application of the user needs to specific behavioral intervention technology dimensions (eg, technology platform). We provide examples of considerations relevant to each stage of this process and how they were applied. This process can guide the initial design of other culturally informed behavioral intervention technologies. This first attempt to create a systematic design process can spur development of guidelines for design of behavioral intervention technologies aimed to reduce health disparities.

    Full Text Available Provider-initiated HIV testing (PITC is increasingly adopted in Europe. The success of the approach at identifying new HIV cases relies on its effectiveness at testing individuals most at risk. However, its suitability to reach populations facing overlapping vulnerabilities is under researched. This qualitative study examined HIV testing experiences and perceptions amongst Latin-American migrant men who have sex with men and transgender females in Spain, as well as health professionals' experiences offering HIV tests to migrants in Barcelona and Madrid.We conducted 32 in-depth interviews and 8 discussion groups with 38 Latin-American migrants and 21 health professionals. We imported verbatim transcripts and detailed field work notes into the qualitative software package Nvivo-10 and applied to all data a coding framework to examine systematically different HIV testing dimensions and modalities. The dimensions analysed were based on the World Health Organization "5 Cs" principles: Consent, Counselling, Connection to treatment, Correctness of results and Confidentiality.Health professionals reported that PITC was conceptually acceptable for them, although their perceived inability to adequately communicate HIV+ results and resulting bottle necks in the flow of care were recurrent concerns. Endorsement and adherence to the principles underpinning the rights-based response to HIV varied widely across health settings. The offer of an HIV test during routine consultations was generally appreciated by users as a way of avoiding the embarrassment of asking for it. Several participants deemed compulsory testing as acceptable on public health grounds. In spite of--and sometimes because of--partial endorsement of rights-based approaches, PITC was acceptable in a population with high levels of internalised stigma.PITC is a promising approach to reach sexual minority migrants who hold high levels of internalised stigma but explicit extra efforts are needed

    To review literature on identifying the risk factors associated with early sexual coerced debut with the aim to facilitate the health care workers' planning of relevant health services to improve intervention strategies for delaying of early coerced sexual debut or forced sexual debut (CSD/FSD) in the communities. Identifying the risk factors associated with coercion at first sex is crucial for developing appropriate sexual and reproductive health information and health promotion in response. However, current knowledge about the risk factors associated with coercion, sexual debut (SD), and delayed SD among young people is limited. Health information programs are important during adolescence, when young people are developing their values and beliefs about sexual activity and sexual norms. However, little is known about those risk factors on initiation of early sexual debut in order to plan relevant interventions that can delay SD and prevent coerced sexual debut or forced sexual debut (CSD/FSD) in this population. A systematic review. An extensive literature search using Medline (PubMed), Nursing Journals (PubMed), Web of Science, PsychINFO and CINAHL. The search generated 39 published studies that met our inclusion and exclusion criteria. Thirty-two articles passed the quality appraisal and were selected. This review identified six domains of risk factors, categorized as: (1) the individual domain, (2) the family domain, (3) the partner/peer domain, (4) the school domain, (5) the community domain, and (6) the cultural domain. These factors highlight the influences on sexual decision-making among adolescents and young people and the timing of their first sexual intercourse. It is important to utilize the outcome of this review's categorization of identified risk factors to facilitate the health care workers and plan relevant sexual and reproductive health programs more accessible to adolescents, especially young females and their parents. There is a need to evaluate

    Full Text Available This study aimed to identify standards and expectations regarding sexual initiation of 14 to 18 year-old adolescents in Sao Paulo, SP, Brazil, using data from four focal groups conducted in 2006. Results revealed that gender issues are clearly present in participants' reports and showed to be essential in their choices about the moment, partners and contraceptive practices in the first sexual relation. Adolescents are subordinated to gender roles, traditionally attributed to male and female genders, i.e. the notion that sex is an uncontrolled instinct for boys, and intrinsically and closely associated to love and desire for girls. Adolescents also play a preponderant role in the perpetuation of these values within the group they live in.Con el objetivo de identificar las normas y expectativas sociales que se encuentran en la iniciación sexual, fueron estudiados cuatro grupos de adolescentes entre 14 y 18 años de edad, en 2.006, en la ciudad de San Pablo, Brasil. Los datos mostraron que las cuestiones de género están claramente presentes en los discursos de los entrevistados y se mostraron fundamentales en las elecciones sobre: el momento, el compañero y las prácticas contraceptivas que se encuentran en la vivencia de la primera relación sexual. Los adolescentes están subordinados a los papeles de género, tradicionalmente atribuidos a los hombres y a las mujeres, y al concepto de que el sexo es un instinto físico e incontrolable entre los muchachos, y a la intrínseca relación entre el amor, el deseo y el sexo entre las muchachas; estas percepciones tienen también un papel preponderante para mantener estos valores en el grupo en que viven.Com o objetivo de identificar normas e expectativas sociais que cercam a iniciação sexual, foram estudados quatro grupos focais com adolescentes de 14 a 18 anos de idade, em 2006, na cidade de São Paulo, Brasil.

    This study examined whether the development of sexualized media consumption and permissive sexual attitudes would be more strongly interrelated when adolescents perceived sexualized media images as highly realistic. We used data from a three-wave longitudinal sample of 444 Dutch adolescents aged 13-16 years at baseline. Results from parallel process latent growth modeling multigroup analyses showed that higher initial levels of sexualized media consumption were associated with higher initial level of permissive sexual attitudes. Moreover, increases of sexualized media consumption over time were associated with increases of permissive sexual attitudes over time. Considering the moderation by perceived realism, we found these effects only for those who perceived sexualized media as more realistic. Findings for male and female adolescents were similar except for the relations between initial levels and subsequent development. Among male adolescents who perceived sexualized media images to be realistic, higher initial levels of permissive sexual attitudes were related to subsequent less rapid development of sexualized media consumption. For male adolescents who perceived sexualized media to be less realistic, higher initial levels of sexualized media consumption were related to a subsequent less rapid development of permissive sexual attitudes. These relations were not found for female adolescents. Overall, our results suggest that, in male and female adolescents, those with a high level of perceived realism showed a correlated development of sexualized media consumption and permissive sexual attitudes. These findings point to a need for extended information on how to guide adolescents in interpreting and handling sexualized media in everyday life.

    Full Text Available The current study focuses on factors associated with sexual initiation and condom use among teenagers on Santiago Island, Cape Verde, according to gender. This was a representative, probabilistic sample of 13-to-17-year-olds (n = 768 attending public secondary schools on Santiago Island in 2007. Associations were tested by test of proportion, Pearson's chi-square, or Fisher's exact test and logistic regression. Factors related to sexual initiation among boys were: age over 14 years, Catholic religion, and alcohol consumption. For girls, the factors included: > 9 years of schooling and involvement in an affective-sexual relationship. Unlike other Sub-Saharan countries, this study showed a high prevalence of condom use during initial sexual activity. Adolescents are able to safely begin sexually active life if they have access to information, sex education, and other STD prevention and contraceptive methods. This study provides insights on the development of policies to reduce the vulnerability of the young population to STD/AIDS and the limits and challenges related to the promotion of condom use and sex education, focusing on unequal gender relations.Foram analisados fatores associados ao início da vida sexual de adolescentes na Ilha de Santiago, Cabo Verde, segundo sexo.

A associação foi testada pelo teste de proporção, qui-quadrado de Pearson ou Fisher e regressão logística. Nos rapazes, os fatores associados ao início da vida sexual foram: idade maior que 14 anos, ser católico e consumo de bebidas alcoólicas. Para meninas: escolaridade maior que nove anos e ter parceiro afetivo-sexual. Ao contrário de outros contextos da África Subsaariana, foram constatadas taxas elevadas de uso de preservativo por adolescentes no início da vida sexual. Os adolescentes podem iniciar a

    analyses indicated that youth who listened to more degrading sexual content at T2 were more likely to subsequently initiate intercourse and to progress to more advanced levels of noncoital sexual activity, even after controlling for 18 respondent characteristics that might otherwise explain these relationships. In contrast, exposure to nondegrading sexual content was unrelated to changes in participants' sexual behavior. Listening to music with degrading sexual lyrics is related to advances in a range of sexual activities among adolescents, whereas this does not seem to be true of other sexual lyrics. This result is consistent with sexual-script theory and suggests that cultural messages about expected sexual behavior among males and females may underlie the effect. Reducing the amount of degrading sexual content in popular music or reducing young people's exposure to music with this type of content could help delay the onset of sexual behavior.

    Full Text Available Aim. The purpose of this research was to explore the subject of sexual activity in the Polish population, with special focus on age and gender differences, and sexual infidelity. Sexual activity is one of the basic factors in initiating and maintaining relationships. On the one hand, sexual activity enables us to meet natural needs and maintain an intimate relationship with another human being; on the other, it may allow us to overcome loneliness and social isolation by providing the opportunity to express feelings of closeness and unity. Material and method. The research was conducted on a representative group of 3,200 Poles aged between 15–49, with the support of a well-known Polish research company – TNS OBOP. Face-to-face and Pencil and Paper (PAPI interviews were carried out. Results. The results focus on two main issues: the age and motives of sexual initiation among teenagers (with a significant percentage starting their sexual activity at the age of 15, and the quality of the sexual lives of adults (average number of sexual partners, sexual infidelity and sexual satisfaction. Conclusion. There is dependence between the type of relationship and the performance or non-performance of sexual activity, as well as the quality of the relationship. Among both adolescents and adults, remaining in a stable relationship (partnership or marriage promotes loyalty. The performance of sexual goals turns out to be an important mechanism regulating the interpersonal aspects of a relationship, influencing their perception and evaluation.

    Background Successful combination antiretroviral therapy (cART) increases levels of CD4+ T-cells, however this increase may not accurately reflect long-term immune recovery since T-cell dysregulation and loss of T-cell homeostasis often persist. We therefore assessed the impact of a decade of effective cART on immune regulation, T-cell homeostasis, and overall T-cell phenotype. Methods We conducted a retrospective study of 288 HIV+ cART-naïve patients initiating therapy. We identified 86 individuals who received cART for at least a decade, of which 44 consistently maintained undetectable plasma HIV-RNA levels throughout therapy. At baseline, participants were classified into three groups according to pre-treatment CD4+ T-cell counts: Group I (CD4350 cells/mm3). Outcomes of interest were: (1) CD4+ T-cell count restoration (CD4>532 cells/mm3); (2) normalization of CD4:CD8 T-cell ratio (1.2–3.3); (3) maintenance of CD3+ T-cell homeostasis (CD3: 65%–85% of peripheral lymphocytes); (4) normalization of the complete T-cell phenotype (TCP). Results Despite a decade of sustained successful cART, complete T-cell phenotype normalization only occurred in 16% of patients, most of whom had initiated therapy at high CD4+ T-cell counts (>350 cells/mm3). The TCP parameter that was the least restored among patients was the CD4:CD8 T-cell ratio. Conclusions Failure to normalize the complete T-cell phenotype was most apparent in patients who initiated cART with a CD4+ T-cell count <200 cells/mm3. The impact of this impaired T-cell phenotype on life-long immune function and potential comorbidities remains to be elucidated. PMID:24710051

    The process from initial concerns to diagnosis of autism spectrum disorder (ASD) can be a long and complicated process. The traditional model for evaluation and diagnosis of ASD often consists of long wait-lists and evaluations that result in a 2-year difference between the earliest signs of ASD and mean age of diagnosis. Multiple factors contribute to this diagnostic bottleneck, including time-consuming evaluations, cost of care, lack of providers, and lack of comfort of primary care providers to diagnose autism. This article explores innovative clinical models that have been implemented to address this as well as future directions and opportunities.

    To determine whether the initiation of P supplementation as artificial luteal phase support (day -1, day 0, or day +1 of egg donation) in extensive programs of ovum donation influences cycle cancellation, pregnancy outcome, and implantation rate in day 3 embryo transfers. Prospective randomized trial. Oocyte donation program at the Instituto Valenciano de Infertilidad, Valencia, Spain. Three hundred recipients with normal ovarian function, absence of uterine anomalies, and undergoing their first egg donation were recruited between September 2003 and September 2004. A computer-based randomization divided the recipients into three groups when hCG was administered to their matched donors. The first group (group A) started P supplementation the day before oocyte retrieval; the second group (group B) started P supplementation on the day of the oocyte retrieval; and the third group (group C) started P supplementation 1 day after the egg retrieval once fertilization was confirmed. Implantation, pregnancy, and ongoing pregnancy rates were the primary outcome measures considered. The secondary outcome measure was the cancellation rate, especially due to fertilization failure. Global cancellation rate and cancellation rate due to fertilization failure were significantly higher in group A (12.4% and 8.2%, respectively) than in group C (3.3% and 0%, respectively). Reproductive outcome was similar in all the groups except for a higher biochemical pregnancy rate in group A (12.9%) than in groups B (6.6%) and C (2.3%). Initiation of P on day +1 of embryo development decreases cancellation rates of day 3 embryo transfers in extensive programs of ovum donation without any deleterious effect on pregnancy outcome or implantation rate.

    Abstract Background: Traumatic diaphragmatic hernias (TDHs) are sometimes difficult to identify at an early stage and can consequently result in diagnostic delays with life-threatening outcomes. It is the aim of this case study to highlight the difficulties encountered with the earlier detection of traumatic diaphragmatic hernias. Methods: Clinical data of patients who received treatment for delayed traumatic diaphragmatic hernias in registers of the First Affiliated Hospital of Xi’an Jiaotong University from 1998 to 2014 were analyzed retrospectively. Results: Six patients were included in this study. Left hemidiaphragm was affected in all of them. Most of the patients had a history of traffic accident and 1 a stab-penetrating injury. The interval from injury to developing symptoms ranged from 2 to 11 years (median 5 years). The hernial contents included the stomach, omentum, small intestine, and colon. Diaphragmatic injury was missed in all of them during the initial managements. All patients received operations once the diagnosis of delayed TDH was confirmed, and no postoperative mortality was detected. Conclusions: Delayed TDHs are not common, but can lead to serious consequences once occurred. Early detection of diaphragmatic injuries is crucial. Surgeons should maintain a high suspicion for injuries of the diaphragm in cases with abdominal or lower chest traumas, especially in the initial surgical explorations. We emphasize the need for radiographical follow-up to detect diaphragmatic injuries at an earlier stage. PMID:27512848

Following a historic outline, we examine the theories that inspired by Laplanche, once more discuss infantile sexuality, and argue that infantile sexuality is clarified by combining the concept of the drive with what in effect is an inter-subjective point of view....

    The relationship of antihypertensive drugs have a long history of association with sexual dysfunction; however, this relationship is poorly documented. There appears to be a higher rate of sexual dysfunction in untreated hypertensive men compared with normotensive men. Sexual dysfunction increases with age and is associated with physical and emotional symptoms. There are few studies assessing sexual dysfunction with female and African-American hypertensive patients. Sexual dysfunction is associated with impairment of quality of life and noncompliance. Since group data may hide individual drug effects, baseline data should be collected on all patients before initiating therapy with any antihypertensive agent. Although questionnaires may not provide objective information on sexual dysfunction, the response rate to direct questioning may be less than the response rate on a questionnaire and may be affected by the gender or race of the interviewer. Research protocols using a double-blind, placebo-controlled design should assess sexual dysfunction in men and women in a standardized fashion.

Methods Clinical data of 236 patients who were proved to have delayed traumatic intracranial hematoma by CT imaging in our hospital from 2005 to 2009 were retrospectively analyzed. The clinical and CT imaging features were summarized. Results Delayed hematomas usually occurred within 3 days after injury and had frontotemporal predilection. It was more common in the elderly. Progressive decline in consciousness and nerve system signs newly found were more indicative of delayed hematoma. When initial CT imaging showed scalp hematoma, skull fractures, gas skull, brain contusion, subarachnoid hemorrhage, hematoma of lateral fissure and other early warning signs, clinicians would be alert to delayed hematomas. Conclusion If the first CT scanning reveals scalp hematoma, cranial fracture,brain contusion, subarachnoid hemorrhage or lateral fissure hematoma, and the clinical symptoms fail to be alleviated and the patients

    This analysis assessed patterns of sexual experience, the order in which behaviors were initiated, and associated factors, among Latino and African American ninth grade students (average age 15.2) who self-administered audio-computer-assisted surveys on netbooks in classes at 10 Los Angeles-area public high schools. Lifetime experiences with vaginal and oral sex were most common (19% and 16%, respectively); fewer reported anal sex (6%). Of the 23% reporting any sex, 91% fell into four categories: 36% reporting both oral and vaginal sex; 23% vaginal only; 18% all three; and 13% oral only. Most sexually experienced students (88%) initiated with vaginal or oral sex (46% vaginal, 33% oral, 9% both same day). No dominant pathway of sexual onset emerged for those reporting all three types of sex. We found no evidence that oral or anal sex substituted for or delayed vaginal sex. Males, those with a current partner, and those reporting multiple partners were more likely than others to report all three sexual behaviors versus vaginal only (odds ratios [ORs] 2.0, 1.5, 3.0; p = .02, .06, < .01, respectively). Although vaginal intercourse dominated their early sexual behavior, one-fifth of sexually experienced students reported anal intercourse, highlighting the need for specific prevention messages surrounding this higher-risk behavior.

    Full Text Available The current study sought to answer three key questions about explaining the emotion of regret in the domain of casual sex: Are sex differences in sexual regret robust or attenuated in a highly egalitarian culture? What proximate psychological variables might explain sex differences in sexual regret? And what accounts for within-sex variation in experiences of sexual regret about casual sex. We conducted a study of 263 Norwegian students (ages 19–37 who reported how much they regretted having either engaged in, or passed up, their most recent casual sexual experience. Sex differences in sexual regret are not attenuated in this sexually egalitarian culture. The study revealed sex differences in worries about pregnancy, STIs, and reputation; however, these predictors did not succeed in accounting for the sex differences in regret engaging in casual sex. Sexual gratification and socio-sexual orientation both predicted the sex differences in casual sex regret. In contrast, only socio-sexual orientation attenuated the sex difference in regret passing up casual sex. Predictors of within-sex variation in casual sexual regret included worry about sexual reputation, experienced gratification during the encounter, and socio-sexual orientation. Discussion focuses on implications for the psychological design features of this relatively neglected emotion.

    Full Text Available Introduction. There is an ample evidence of the impact of severe traumatic events, such as sexual abuse in childhood, on the formation of disorders - especially the non-psychotic ones: sexual, neurotic and personality. So far, an increase of the risk with the accumulation of traumatic factors has been indicated, but less attention has been paid to adverse events such as lack of sexual education, negative attitudes of the caregivers towards sexuality, etc. Aim. Assessment of the risk of such adverse events in childhood and adolescence, concerning the symptoms from the area of sexuality as well as other neurotic disorders areas.Method. The coexistence of the earlier life circumstances and currently present symptoms was examined on the basis of KO„0” Symptom Checklist and Life Inventory, completed prior to treatment in a day hospital for neurotic disordersResults. In the group of 2582 females and 1347 males, there was a significant prevalence of symptoms related to sexuality, as well as of other neurotic symptoms. Patients reported traumatic events of varying frequency (from a relatively rare incest, to much more frequent sense of lack of sex education. Regression analyses showed a significant relationship between the analyzed events and symptoms, for instance, lack of sexual satisfaction in adulthood co-occurred in women with punishing for childhood sexual plays or masturbation. The other analyzed symptoms – ‘non-sexual’, such as panic attacks, were not so clearly related to the burdensome circumstances.Conclusions. The presence of adverse life events concerning sexuality, not necessarily the most serious ones e.g. abuses, but such as inadequate sex education, child punishing for masturbation or sexual plays, unwanted sexual initiation, are associated with a higher occurrence of most of the analyzed symptoms in the sphere of sexuality. Weaker connection for other than sexual neurotic symptoms suggests that the impact of childhood sexual

    Women suffering from eating disorders, present considerable retardation and difficulties in their psychosexual development during adolescence. This leads to primary or secondary insufficiencies in their adult sexual life. The cause of these difficulties seems to be a series of biological, family and psychosocial factors. The majority of the research findings indicate that eating disorders have a negative impact on the patient's sexual function. The factors related to eating disorders symptomatology that influence sexuality are various and differ among each eating disorder diagnostic categories. Considering anorexia nervosa, it has been reported that women have negative attitudes to sexual issues and their body. Their sexual motivation increases when they engage in psychotherapy and their body weight is gradually restored. Starvation and its consequences on the human physiology and especially on the brain function seem to be the main factor that leads to reduced sexual desire and scarce sexual activity. Moreover, personality traits that are common in patients suffering from anorexia nervosa such as compulsivity and rigidity are also related with difficulties initiating and retaining romantic and sexual relationships. Usually patients suffering from anorexia nervosa report impaired sexual behavior and lack of interest to engage in a sexual relationship. Considering Bulimia Nervosa, impulsivity and difficulties in emotion regulation that are common features of the individuals that suffer from bulimia nervosa are also related to impulsive and sometimes self-harming sexual behaviors. Moreover women sufferers often report repulsion, anger and shame towards their body and weight, mainly due to the distorted perception that they are fat and ugly. It is interesting that a number of research findings indicate that although patients suffering from bulimia nervosa are more sexually active and have more sexual experiences than patients suffering from anorexia nervosa, both

    Youth under 25 show substantial sexual and substance use risk behaviors. One factor associated with risk behaviors is delay discounting, the devaluation of delayed outcomes. This study determined if delay discounting for sexual outcomes is related to sexual risk and substance use among 18-24 year olds. Females (70) and males (56) completed the Sexual Discounting Task, which assessed their likelihood of having unprotected immediate sex versus waiting for sex with a condom, at various delays, with 4 hypothetical sexual partners selected from photographs: the person they most wanted to have sex with, least wanted to have sex with, judged most likely to have a sexually transmitted infection (STI), and judged least likely to have an STI. They also completed instruments assessing HIV knowledge, sexual behaviors, substance use, risk attitudes, inhibition, impulsivity, and sensation-seeking. Condom use likelihood generally decreased with increasing delay. Preference for immediate, unprotected sex was greater for partners whom participants most (vs. least) wanted to have sex with and judged least (vs. most) likely to have an STI. Preference for immediate, unprotected sex in the "most want to have sex with" and "least likely to have an STI" conditions was related to greater lifetime risky sexual partners, lifetime number of unique substances used, disregard of social approval/danger, disinhibition, and sensation/excitement-seeking. Males showed greater likelihood of unprotected sex than females when condom use was undelayed, but delay similarly affected condom use between sexes. Delay discounting should be considered in strategies to minimize youth risk behavior.

    Adolescent sexual activity is increasing globally. Abstinence and a delay in the start of sexual intercourse may be the most effective methods in preventing the consequences of teenage sexual activity. However, these goals are seldom met. With the change in social norms, peer pressure and media influences; teenagers are engaging in premarital sex earlier. Family life education in countries like Sweden and Finland reduces teenage pregnancy and abortion. It is unrealistic to expect sexually active adolescents to stop their sexual activity. An effective contraceptive method will provide an alternative to prevent teenage pregnancy. Issues on compliance of contraceptive use, especially at the very outset of sexual activity should be addressed. Most of the problems associated with teenage pregnancy are now thought to be related to the social circumstances of the mother, the poor nutritional status before pregnancy and poor attendance at antenatal clinics. Risk-taking behaviour in this age group will also make them more prone to contracting sexually transmitted diseases. High risk groups should be screened and treated early. Contraceptive methods with protection against sexually transmitted diseases should be advised.

The reported incidence of sexual dysfunction associated with antidepressant medication varies considerably between studies, making it difficult to estimate the exact incidence or prevalence. The sexual problems reported range from decreased sexual desire, decreased sexual excitement, diminished or delayed orgasm, to erection or delayed ejaculation problems. There are a number of case reports of sexual side effects, such as priapism, painful ejaculation, penile anesthesia, loss of sensation in the vagina and nipples, persistent genital arousal and nonpuerperal lactation in women. The focus of this article is to explore the incidence, pathophysiology, and treatment of antidepressant iatrogenic sexual dysfunction.Keywords: depression, antidepressant, iatrogenic sexual dysfunction, SSRI, SNRI

  16. Basin stability in delayed dynamics

    2016-02-01

    Basin stability (BS) is a universal concept for complex systems studies, which focuses on the volume of the basin of attraction instead of the traditional linearization-based approach. It has a lot of applications in real-world systems especially in dynamical systems with a phenomenon of multi-stability, which is even more ubiquitous in delayed dynamics such as the firing neurons, the climatological processes, and the power grids. Due to the infinite dimensional property of the space for the initial values, how to properly define the basin’s volume for delayed dynamics remains a fundamental problem. We propose here a technique which projects the infinite dimensional initial state space to a finite-dimensional Euclidean space by expanding the initial function along with different orthogonal or nonorthogonal basis. A generalized concept of basin’s volume in delayed dynamics and a highly practicable calculating algorithm with a cross-validation procedure are provided to numerically estimate the basin of attraction in delayed dynamics. We show potential applicabilities of this approach by applying it to study several representative systems of biological or/and physical significance, including the delayed Hopfield neuronal model with multistability and delayed complex networks with synchronization dynamics.

    Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35–40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

    Full Text Available The aim of this study was to examine characterisctics of precoital sexual behaviors and types of sexual contact in adolescent. A representative sample of 4,456 Spanish high school students participated. These participants were selected by means of a stratified random sampling procedure. They completed a questionnaire about their sexual behaviour. It is a cross-sectional survey study. Differences according to age and gender in characteristics of sexualbehaviour before the onset of sexual intercourse were found. Comparedto females, males started non penetrative sexual experiences earlier, had a higher number of sexual partners and a higher percentage of males reported having had casual sexual partner. This study not only adds to knowledge about sexual behaviour before the initiation of sexual intercourse among adolescents, it also highlights the importance of developing sexual prevention strategies for young adolescents.

    Full Text Available Abstract Background There is continuing concern about high pregnancy rates and increasing numbers of sexually transmitted infections being detected in Scottish adolescents. Consistent evidence about factors associated with risky sexual behaviours, including early first sexual intercourse, may help to identify adolescents at risk and help improve interventions. This study aimed to provide detailed analysis of the evidence of the associations between individual factors and early sexual intercourse using cross-sectional questionnaire data from 4,379 Scottish adolescents who participated in a sexual health intervention evaluation. Findings Multivariate secondary analysis showed that aspects of family and school life such as decreasing parental monitoring (OR 1.45, 95% CI 1.24–1.70 and decreasing enjoyment of school (OR 2.55, 95% CI 2.15–3.03 were associated with reporting previous sexual intercourse. Furthermore, females were more likely to report previous sexual intercourse than males (OR 1.48, 95% CI 1.14–1.91. Several factors commonly used to inform sexual health intervention design, such as socioeconomic status, self-esteem and religion, were not independently associated. Conclusion These results contribute to the evidence base for the association of several factors with early initiation of sexual activity. The findings suggest that interventions aiming to delay first intercourse may need to consider targeting aspects of individuals' connection to their school and family. Furthermore, the results do not support the need to consider socio-economic background, religion or self-esteem of the individuals in intervention design.

    2014-02-01

    Asexuality is an emerging identity category that challenges the common assumption that everyone is defined by some type of sexual attraction. Asexuals--those who report feeling no sexual attraction to others--constitute one percent of the population, according to one prominent study. In recent years, some individuals have begun to identify as asexual and to connect around their experiences interacting with a sexual society. Asexuality has also become a protected classification under the antidiscrimination law of one state and several localities, but legal scholarship has thus far neglected the subject. This Article introduces asexuality to the legal literature as a category of analysis, an object of empirical study, and a phenomenon of medical science. It then offers a close examination of the growing community of self-identified asexuals. Asexual identity has revealing intersections with the more familiar categories of gender, sexual orientation, and disability, and inspires new models for understanding sexuality. Thinking about asexuality also sheds light on our legal system. Ours is arguably a sexual law, predicated on the assumption that sex is important. This Article uses asexuality to develop a framework for identifying the ways that law privileges sexuality. Across various fields, these interactions include legal requirements of sexual activity, special carve-outs to shield sexuality from law, legal protections from others' sexuality, and legal protections for sexual identity. Applying this framework, the Article traces several ways that our sexual law burdens, and occasionally benefits, asexuals. This Article concludes by closely examining asexuality's prospects for broader inclusion into federal, state, and local antidiscrimination laws.

    Garcia, Frederico Duarte; Thibaut, Florence

    2010-09-01

    The potential adverse consequences, personal distress, shame and guilt presented by patients who suffer from sexual addiction require a more in-depth understanding of the phenomenology and psychobiology of this disorder. A bibliographic review was conducted using MEDLINE and EBSCO databases with the following keywords: "sexual addiction," "hypersexuality," "compulsive sexual behavior," "behavioural addiction," "treatment," and "addiction." Several conceptualizations of excessive nonparaphilic sexual disorder have been proposed based on the models of, respectively, obsessive compulsive disorder, impulse control disorder, out of control excessive sexual disorder, and addictive disorder. Despite the lack of robust scientific data, a number of clinical elements, such as the frequent preoccupation with this type of behavior, the time spent in sexual activities, the continuation of this behavior despite its negative consequences, the repeated and unsuccessful efforts made to reduce the behavior, are in favor of an addictive disorder. In addition there is a high comorbidity between excessive sexual behavior and other addictive behaviors. The phenomenology of excessive nonparaphilic sexual disorder favors its conceptualization as an addictive behavior, rather than an obsessive-compulsive, or an impulse control disorder. Moreover, the criteria that are quite close to those of addictive disorders were recently proposed for the future DSM-V in order to improve the characterization of this condition. Finally, controlled studies are warranted in order to establish clear guidelines for treatment of sexual addiction.

    Examining a victim of sexual assault is a medico-legal emergency. It has to be performed within 72 h, in appropriate conditions. A recent laceration of the hymen does not necessarily indicate a rape, and conversely absence of trauma to a rape victim does not negate the validity of her claim to rape. A normal clinical examination does not exclude the possibility of a sexual abuse. Unlawful sexual intercourse is defined by a sexual penetration without valid consent. Specimen collection, to be considered as an evidence, must be sealed. Toxicological samples have to be performed to search a rape under influence.

  6. Internet Sexualities

    Science.gov (United States)

    Döring, Nicola

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

  9. Women's luteal-phase sexual proceptivity and the functions of extended sexuality.

    Grebe, Nicholas M; Gangestad, Steven W; Garver-Apgar, Christine E; Thornhill, Randy

    2013-10-01

    Women's sexuality, unlike that of most mammals, is not solely defined by sexual receptivity during the short window of fertility. Women demonstrate extended sexuality (in which they initiate and accept sexual advances outside of the fertile phase) more than any other mammalian female. In this light, surprisingly little research has addressed the functions of women's luteal-phase sexuality. On the basis of theory and comparative evidence, we propose that women's initiation of sex during nonfertile phases evolved in part to garner investment from male partners. If so, women should be particularly prone to initiate luteal-phase sex when the potential marginal gains are greatest. Results from a study of 50 heterosexual couples showed that women increasingly initiate sex in the luteal phase (but not the fertile phase) when they perceive their partners' investment to lag behind their own. These findings provide evidence for the distinct nature of women's extended sexuality and may contribute to a more comprehensive understanding of women's sexuality.

  10. The effects of beta-endorphin infusions into the amygdala on visual and olfactory sensory processing during sexual behaviour in the male rat.

    McGregor, A; Herbert, J

    1992-01-01

    Sexually experienced male rats infused bilaterally into the amygdala with 60 pmol beta-endorphin show decreased rate of precopulatory investigation of the female and delayed intromission latency, but copulation is left unaltered. Such males are still able to discriminate between the odours of bedding from receptive and unreceptive females, demonstrating that beta-endorphin does not impair the ability to detect sexually relevant odours. Preventing visual cues emitted by females during proceptive behaviour (by treating them with haloperidol) delayed intromission latency but had no effect on preintromission investigation. Intra-amygdaloid beta-endorphin exacerbated the effects of this treatment on the intromission latency. Inducing anosmia in males (by applying zinc sulphate solution to the olfactory mucosa) decreased their anogenital investigation and delayed their intromission latency. These effects were not enhanced by intra-amygdaloid beta-endorphin. Allowing males to investigate and initiate the first intromission prior to intra-amygdaloid infusion had no effects on subsequent intromissions. However, if following an intromission with one female and an infusion of beta-endorphin, the male was presented with an unfamiliar female then the effects of intra-amygdaloid beta-endorphin on investigation and intromission returned. These results suggest that beta-endorphin in the amygdala interferes with the processing of female-specific olfactory information. Without this processed information, classification of the female as a sexual stimulus may be impeded and thus sexual arousal delayed.

    Despite shifts toward greater acceptance in U.S. public opinion and policy, lesbian, gay, and bisexual people remain widely stigmatized. This article reviews empirical research on sexual prejudice, that is, heterosexuals' internalization of cultural stigma, manifested in the form of negative attitudes toward sexual minorities and same-sex desires and behaviors. After briefly reviewing measurement issues, we discuss linkages between sexual prejudice and religion, gender, sexuality, and related variables, and consider how the cultural institutions encompassing these domains create a social context within which individual expressions of prejudice can meet important psychological needs. These include needs for securing social acceptance, affirming values that are central to one's self-concept, and avoiding anxiety and other negative emotions associated with threats to self-esteem. We conclude by discussing factors that may motivate heterosexuals to reduce their own sexual prejudice, including intergroup contact, as well as avenues for future empirical inquiry.

    Full Text Available Abstract Background Circumstances surrounding injection initiation have not been well addressed in many developing country contexts. This study aimed to identify demographic factors, sexual behaviors and drug use characteristics related to injection initiation among drug users in northern Thailand. Methods A cross-sectional survey was conducted among 2,231 drug users admitted to the Northern Drug Treatment Center in Mae Rim, Chiang Mai, Thailand, between February 1, 1999 and December 31, 2000. A multiple logistic regression was employed to identify the independent effects from potential risk factors of transition into injection. Results After controlling for other covariates, being 20 years of age or older, single, ever receiving education, urban residence, and having a history of smoking or incarceration were significantly associated with higher likelihood of injection initiation. Multiple sex partners and an experience of sex abuse were associated with an increased risk of injection initiation. Comparing to those whose first drug was opium, individuals using heroin as their initiation drug had greater risk of injection initiation; conversely, those taking amphetamine as their first drug had less risk of injection initiation. Age of drug initiation was negatively associated with the risk of injection initiation: the older the age of drug initiation, the less the risk of injection initiation. Conclusion Injection initiation was related to several demographic factors, sexual behaviors and drug use characteristics. Understanding these factors will benefit the design of approaches to successfully prevent or delay transition into injection.

    Sexual dysfunction is a common side effect of antidepressants and can have significant impact on the person's quality of life, relationships, mental health, and recovery. The reported incidence of sexual dysfunction associated with antidepressant medication varies considerably between studies, making it difficult to estimate the exact incidence or prevalence. The sexual problems reported range from decreased sexual desire, decreased sexual excitement, diminished or delayed orgasm, to erection or delayed ejaculation problems. There are a number of case reports of sexual side effects, such as priapism, painful ejaculation, penile anesthesia, loss of sensation in the vagina and nipples, persistent genital arousal and nonpuerperal lactation in women. The focus of this article is to explore the incidence, pathophysiology, and treatment of antidepressant iatrogenic sexual dysfunction.

    A survey of knowledge, attitude, and practices regarding human reproduction and sexuality was undertaken in 2 groups of secondary school students in Chile to assess whether greater knowledge of reproduction and sexuality is associated with greater permissiveness and earlier initiation of sexual activity. Students in 2 public schools, 1 coeducational and 1 for female students only, were of lower middle class background, while students at the coeducational private school were of higher socioeconomic status. An anonymous, semiclosed questionnaire was administered to students in the 3 schools. The schools were selected because their directors agreed to permit the study. 14.8% of the 351 public school students were aged 14 or under and 77.8% were 15-18, while 99.5% of the 197 private school students were aged 15-18. The students' levels of knowledge of human reproduction and sexuality were measured through direct personal assessments by the students themselves and through 21 questions to confirm the assessments. At least 93% of students in all schools said their level of knowledge was medium or high, but the test indicated that only 64% of public school students and 75% of private school students actually had medium or high levels of knowledge. 45.9% of private and 27.9% of public school students felt the information they received from their schools about sexuality was adequate, while 41.9% of private and 60.9% of public school students felt it was insufficient. There were no significant differences in the opinions of the 2 groups of students concerning premarital sex, but the reasons given by the private school students to explain their attitudes expressed a greater sense of commitment to the partner, while those of the public school students tended to be more functional. Among public school students, 38.7% of males and 9.7% of females reported having had sexual relations, while among private school students, 17.7% of males and 4.4% of females reported having done so

  2. Delayed childbearing.

    In many Western nations, including England and Wales, Sweden, and the US, there is a current trend towards delayed childbearing because of women's pursuit of a career, later marriage, a longer interval between marriage and the 1st birth, and the increasing number of divorcees having children in a 2nd marriage. Wives of men in social classes I and II in England and Wales are, on average, having their 1st child at 27.9 years, 1.6 years later than in 1973, and in social classes IV and V, 1.0 years later than in 1973, at a mean age of 23.7 years. Consequently, the total period fertility rate for British women aged 30-34 years, 35-39 years, and 40 and over increased by 4%, 2%, and 4%, respectively, between 1982-83, in contrast to reductions of 2% and 3%, respectively, in the 15-19 year and 20-24 year age groups, with the 25-29-year-olds remaining static. The average maternal mortality for all parties in England and Wales during 1976-78 was 106/million for adolescents, 70.4/million for 20-24 year-olds, and 1162/million for those aged 40 years and older. The specific obstetric and allied conditions which increase with age are the hypertensive diseases of pregnancy, hemorrhage, pulmonary embolism, abortion, cardiac disease, caesarean section, ruptured uterus, and amniotic fluid embolism. The Swedish Medical Birth Registry of all live births and perinatal deaths since 1973 has shown that the risk of late fetal death is significantly greater in women aged 30-39 years than in those of the same parity and gravidity aged 20-24 years. The risk of giving birth to low birth weight babies preterm and at term and of premature labor are similarly increased. The early neonatal death rate also was increased for primigravidas and nulliparas in the 30-39 year age group but not in parous women. This is, in part, due to the rise in incidence of fetal abnormalities with advancing maternal age because of chromosomal and nonchromosomal anomalies. These also appear to be the cause of the

    Children with juvenile rheumatoid arthritis (JRA) exhibit a compromised growth status while information concerning the pattern of their sexual maturity is scant. The aim of the current work was to study sexual maturity in boys and girls with JRA. The study included eighty JRA patients they were 45 male and 35 female and eighty age- and sex-matched normal children served as controls. Development of genitalia was evaluated as per sexual maturity rating criteria given by Tanner score. Development of hair (pubic, axillary and facial) and age of monarch to JRA females were noted The mean (±SD) age of appearance of genitalia stage G-2 in boys with systemic onset JRA (12.0 ± 0.3 years) was earlier when compared with pauciarticular (12.60 ± 0.93 years) and polyarticular (13.39 ± 0.93 years) JRA but delayed for all types of JRA when compared with controls (10.06 ± 0.63 years). In comparison with female groups, the mean (±SD) age of appearance of genitalia stage G-2 with systemic onset JRA (12.0 ± 0.4 years) was also earlier when compared with pauciarticular (12.68 ± 1.09 years) and polyarticular (13.72 ± 0.39 years). Age of menarche delayed in all JRA female patients. None of the study group reach stage G-5 of genitalia development. The timing of initiation of sexual maturity in boys and girls with JRA delayed and this delay variable according to disease subtype.

    Understanding the role of socio-sexual cognitions and religiosity on adolescent sexual behavior could guide adolescent sexual health efforts. The present study utilized longitudinal data from 328 young women to assess the role of religion and socio-sexual cognitions on sexual behavior accrual (measuring both coital and non-coital sexual behavior). In the final triple conditional trajectory structural equation model, religiosity declined over time and then increased to baseline levels. Additionally, religiosity predicted decreased sexual conservatism and decreased sexual conservatism predicted increased sexual behavior. The final models are indicative of young women's increasing accrual of sexual experience, decreasing sexual conservatism and initial decreasing religiosity. The results of this study suggest that decreased religiosity affects the accrual of sexual experience through decreased sexual conservatism. Effective strategies of sexual health promotion should include an understanding of the complex role of socio-sexual attitudes with religiosity.

  5. Conversion of linear time-invariant time-delay feedback systems into delay-differential equations with commensurate delays

    Yamazaki, Tatsuya; Hagiwara, Tomomichi

    2014-08-01

    A new stability analysis method of time-delay systems (TDSs) called the monodromy operator approach has been studied under the assumption that a TDS is represented as a time-delay feedback system consisting of a finite-dimensional linear time-invariant (LTI) system and a pure delay. For applying this approach to TDSs described by delay-differential equations (DDEs), the problem of converting DDEs into representation as time-delay feedback systems has been studied. With regard to such a problem, it was shown that, under discontinuous initial functions, it is natural to define the solutions of DDEs in two different ways, and the above conversion problem was solved for each of these two definitions. More precisely, the solution of a DDE was represented as either the state of the finite-dimensional part of a time-delay feedback system or a part of the output of another time-delay feedback system, depending on which definition of the DDE solution one is talking about. Motivated by the importance in establishing a thorough relationship between time-delay feedback systems and DDEs, this paper discusses the opposite problem of converting time-delay feedback systems into representation as DDEs, including the discussions about the conversion of the initial conditions. We show that the state of (the finite-dimensional part of) a time-delay feedback system can be represented as the solution of a DDE in the sense of one of the two definitions, while its 'essential' output can be represented as that of another DDE in the sense of the other type of definition. Rigorously speaking, however, it is also shown that the latter representation is possible regardless of the initial conditions, while some initial condition could prevent the conversion into the former representation. This study hence establishes that the representation of TDSs as time-delay feedback systems possesses higher ability than that with DDEs, as description methods for LTI TDSs with commensurate delays.

  6. Elite athletes and pubertal delay.

    Science.gov (United States)

    2017-10-01

    Intensive physical training and participation in competitive sports during childhood and early adolescence may affect athletes' pubertal development. On the other hand, pubertal timing, early or late, may impact on an athlete selection for a particular sport. Genetic predisposition, training load, nutritional status and psychological stress determine athletes' pubertal timing. Athletes that practice esthetic sports, especially gymnasts, are predisposed to a delay in pubertal development. The growing evidence indicates that energy deficiency, not a systemic training per se, plays a crucial role in the pathogenesis of functional hypothalamic hypogonadism in female athletes. Metabolic and psychologic stress activate hypothalamic-pituitary-adrenal axis and suppress hypothalamic-pituitary-ovarian axis. Female athletes who do not begin secondary sexual development by the age of 14 or menstruation by the age of 16 warrant a comprehensive evaluation and a targeted treatment. Somatic growth and sexual maturation of elite female athletes are largely sport-specific since each sport favors a particular somatotype and requires a specific training. Chronic negative energy balance resulting from a systemic physical training and inadequate energy intake may delay pubertal development in elite athletes. Youth athletes, especially those engaged in competitive sports that emphasize prepubertal or lean appearance, are at risk of developing relative energy deficiency in sport associated with disordered eating or eating disorders. Management strategies should address the complex conditions underlying functional hypothalamic hypogonadism.

    Full Text Available Background: Humans are hard-wired to pay attention to violent and sexual cues. Because humans have limited attention capacity, attention allocated to violent and sexual cues decreases attention that can be allocated to encoding important information in school. This study examined the effects of exposure to violent and sexual media on general school performance and Test of English as a Foreign Language (TOEFL scores in Turkish youth. Methods: The relationship between exposure to violent and sexual media on school performance was assessed in a sample of 1545 Turkish adolescents. Then, we compared the TOEFL scores of 143 Turkish boys aged 14 to 18 divided in 71 living in dormitories in which consumption of media was strictly regulated and 72 living at home. Results: A significant negative relationship was found between exposure to violent/sexual media and school success. The effects remained significant even after controlling for the total amount of media exposure. In addition, boys living in the dormitory in which consumption of media was strictly regulated outscored those living at home on the TOEFL post-test immediately after the end of the study, and on a delayed post-test one week later. Conclusions: Because there was no difference between boys living at home and those living in a dormitory on the pre-test, the post-test and delayed post-test differences cannot be attributed to initial differences in English language proficiency. These results suggest that exposure to violent and sexual media impairs adolescent school performance and foreign language memory.

    Sexual coercion may affect the sexual experiences of sexual minority women differently. Women (n=445) aged 18 to 71 years (Mean=30.38) answered an online survey on sexual orientation, lifetime coercion, and sexual history. Sexual minority women (45.8%, n=204) were more likely to report having been coerced into unwanted sexual behavior (56.5%) than heterosexual women (44.8 %; p=0.010). Coerced sexual minority women reported earlier ages of initiation into performing oral sex (p=0.016), penile-vaginal (p=0.024), and penile-anal (p=0.027) intercourse. In multiple logistic regression models, currently being in a partnered relationship was the sole factor related to lifetime engagement in penile-vaginal intercourse and receiving oral sex from partners. Having at least a graduate degree was the only characteristic related to engagement in lifetime penile-anal intercourse. Sexual coercion was not related to any lifetime sexual behavior outcomes. The nature of sexual initiation and coercion should be explored further among sexual minority women, with the goal of incorporating their experiences into prevention and treatment initiatives.

    Full Text Available BACKGROUND: Sickle cell disease, the most common hereditary blood disease in the world, is the result of an atypical hemoglobin called S (Hb S which, when homozygous (Hb SS is the cause of sickle cell anemia. Changes of puberty, correlated with a delayed growth spurt, begin late in both male and female sickle cell anemia individuals with repercussions on sexuality and reproduction. The objectives of this exploratory and descriptive study were to characterize the development of sexuality in adults with sickle cell anemia by investigating the patient's perception of their sex life, as well as the information they had and needed on this subject. METHODS: Twenty male and female sickle cell anemia patients treated at the Hemocentro Regional de Uberaba (UFTM with ages between 19 and 47 years old were enrolled. A socioeconomic questionnaire and a semi-structured interview on sexuality, reproduction and genetic counseling were applied. RESULTS: This study shows that the sickle cell anemia patients lacked information on sexuality especially about the risks of pregnancy and the possible inheritance of the disease by their children. Moreover, the sexual life of the patients was impaired due to pain as well as discrimination and negative feelings experienced in close relationships. CONCLUSION: The health care of sickle cell anemia patients should take into account not only the clinical aspects of the disease, but also psychosocial aspects by providing counseling on sexuality, reproduction and genetics, in order to give this population the possibility of a better quality of life.

  16. Sexual Jealousy

    2013-09-01

    Full Text Available Sexual jealousy is a basic emotion. Although it lacks a distinctive facial expression and is unlikely to solve problems of survival, it evolved because it solves adaptive problems of mating. Some adaptive functions are similar in men and women at one level of abstraction, such as warding off potential mate poachers and deterring relationship defection. Other functions are sex-differentiated, such as increasing paternity probability for men and monopolizing a mate's economic commitments for women. Dozens of studies have documented sex-differentiated design features of jealousy: The relative upset about sexual and emotional aspects of infidelity; processing speed and memorial recall of sexual and emotional infidelity cues; physiological distress to sexual and emotional infidelity cues; qualities of same-sex rivals that evoke jealousy, such as superior job prospects versus greater physical attractiveness; triggers of mate retention tactics; jealous interrogations following the discovery of infidelity; and whether an infidelity produces forgiveness or breakup. Although showing all the hallmarks of evolved functionality, sexual jealousy also leads to tremendous destruction, from humiliation to homicide. By these scientific theoretical and empirical criteria, sexual jealousy is properly considered not only "basic" but also "one of the most important emotions".

    Full Text Available The paper presents the results of an empirical study on the personality traits of sexually active teenagers. The research identified the personality traits of teenagers who are inclined to look for sexual relations. The research focused on the following: motivation and values, implicit representations about sexual contacts, parent-child relations, and self-concept. The study comprised 465 individuals including 405 school students aged 14-16 and 60 mothers of the teenagers examined. The results demonstrate that teenagers' refusal to begin sexual life, provided they have this opportunity (i.e. a partner, is linked to their subjective perception of the basic values reflected in their consciousness. The research also focused on the features of teenagers' implicit representations with regard to sexual intercourse. This allowed to identify the role of sexual intercourse in teenagers' life. The factors regulating sexual relations in the age under study have been revealed. The research shows that teenage sexual intercourse is mainly driven by cognitive motives combined with the hedonistic (boys and communicational/social ones (girls. Emotionally distant parents are another factor triggering sexual relations. The negatively critical attitude to sexual partners was also displayed, especially by girls. The attitude was expressed by teenagers even where they initiated sexual intercourse themselves, without been pressured into it by their partners. The study has an applied character and enables effective preventive and corrective work with sexually active teenagers.

    Body piercing and tattooing are accepted by a growing number of teenagers and young adults as a way of self-expressing. Some authors suggest association between body piercings/tattoos and early sexual initiation, higher number of sexual partners, or risky sexual behaviors. The aim of the study was to evaluate sexual behaviors among young adults with body modifications (BMs)--tattoos and piercings. One hundred twenty young healthy adults, ages between 20 and 35, were included in the population study. The study group was divided into three subgroups: controls (N = 60), adults with tattoos (N = 28), and adults with piercings (N = 32). The research instrument was a self-prepared questionnaire containing 59 questions assessing socioepidemiological parameters, sexual behaviors, incidents of sexual harassment in the past, and self-attractiveness evaluation, as well as questions concerning tattoos and piercings. Socioepidemiological variables and sexual behaviors were compared between subgroups. To assess and describe the correlation between having BM--tattoos and piercing--and sexual behaviors in the population of young adults by using the logistic regression model. Adults with BMs have had their first intercourse statistically earlier and were more sexually active compared with controls. There were no statically significant differences in sexual orientation, sexual preferences, engaging in risky sexual behaviors, frequency of masturbation, and history of sexual abuse between the groups. In contrast, the frequency of sexual intercourses was statistically higher and oral sex was more likely to be a dominant sexual activity in adults with BM compared with controls. The multivariate logistic model revealed that adults with BM were four times less likely to participate in religious practices and twice more likely to have early sexual initiation. Having BM is associated with early sexual initiation and more liberal attitudes toward sexual behaviors but not with engaging in

    Frontotemporal dementia (FTD) is characterized by a number of prominent behavioral changes. While FTD has been associated with the presence of aberrant or unusual sexual behaviors in a proportion of patients, few studies have formally investigated changes in sexual function in this disease. We aimed to systematically quantify changes in sexual behavior, including current symptoms and changes from prior diagnoses, in behavioral-variant (bvFTD) and semantic dementia (SD), compared to Alzheimer's disease (AD). Carers of 49 dementia patients (21 bvFTD, 11 SD, 17 AD) were interviewed using the Sexual Behavior and Intimacy Questionnaire (SIQ), a survey designed to assess changes in sexual function across multiple domains including initiating, level of affection, and aberrant or unusual sexual behavior. BvFTD patients show prominent hyposexual behavior including decreased affection, initiation, and response to advances by partners, and decreased frequency of sexual relations, compared to AD and to SD patients. The greatest changes in sexual behavior compared to pre-diagnoses were found in the bvFTD group with a 90-100% decrease in initiation, response, and frequency of sexual relations. Notably, aberrant or unusual sexual behavior was reported in a minority of bvFTD and SD patients and occurred in patients who also showed hyposexual behavior toward their partner. Overall loss of affection, reduced initiation of sexual activity, and responsiveness is an overwhelming feature of bvFTD. In contrast, aberrant or unusual sexual behavior is observed in the minority of bvFTD patients. The underlying pathophysiology of these changes likely reflects structural and functional changes in frontoinsular and limbic regions including the hypothalamus.

    Full Text Available Aim. Assessment of the association between self-reported sexual complaints and recalled childhood sexual adversities in a sample of psychotherapy patients.Material and methods. Coexistence of memories concerning traumatic events and minor sexual adversities and the currently present symptoms were analyzed on the basis of KO”0” Symptom Checklist andLife Inventory completed prior to treatment in the day hospital for neurotic disorders. Questionnaires from 3929 psychotherapy patients were analyzed. Logistic regression analyses were performed on biographical and symptom items. Odds ratios for men and women were determined separately.Results. Associations between sexual adverse events, and current sexual health complaints, as estimated by OR coefficients, showed to be statistically significant. In the subgroups of patients who reported two categories of sexual adversities e.g. were both punished for masturbation and were not educated about sex, the risk of sexual complaints was further increased.Discussion. Both self-reported traumatic sexual events and sexual problems are quite common in the patient population and are strongly associated. Our study has replicated other’s findings in a large sample of outpatients suffering from neurotic disorders.Conclusions. Deficits in sex education, the trauma of incest, punishment for sexual play or masturbation, or too early or unwanted sexual initiation, are important risk factors of sexual symptoms accompanying neurotic syndromes. Results strongly suggest that studies focusing on the effects of sexual traumatic events should take into consideration the co-occurrence of multiple adversities.

    Full Text Available Objective: The objective of this study was to evaluate the sexual behavior of women with polycystic ovary syndrome and the relationship between sexual behavior and the clinical parameters related to this syndrome (obesity, hirsutism and menstrual irregularities. Methods: A cross-sectional study was carried out involving 48 women with polycystic ovary syndrome. The evaluation was based on the complaints reported by the women with particular emphasis on sexual satisfaction, the presence of a sexual partner, phases of the sexual response cycle (desire, arousal, orgasm and resolution phases, sexual frequency, practice of masturbation, evaluation of less usual sexual habits, degree of intimacy and the quality of communication in the women’s involvement with their sexual partner. The variables of sexual behavior (sexual satisfaction, masturbation, sexual fantasies, frequency of desire, arousal and orgasm were compared with three clinical parameters: menstrual cycle, hirsutism and body mass index (BMI. Results: The sexual initiation, ways of expressing sexuality, communication and intimacy with partner and sexual satisfaction were not influenced by the clinical aspects of the syndrome. With respect to association of polycystic ovary syndrome clinical parameters with sexual behavior, a statistically significant correlation was found with the menstrual cycle. Conclusion: The absence of menstruation affected sexual interest in activities not involving the partner, thus increasing the frequency of masturbation.

    The PLISSIT model is a comprehensive program that combines educational strategies with behavioral intervention to integrate human sexuality into the initial rehabilitation of spinal cord-injured persons. Sexuality is treated as a health care issue as important as bowel and bladder care, skin care, psychosocial issues, mobility, self-care and vocational concerns. Patients admitted to the Spinal Cord Injury Program are surrounded by a supportive milieu and an interdisciplinary staff who comfortably incorporate sexuality into discussions about catheter care, positioning, communication styles, assistive devices and so forth. Patients are exposed to a behavioral training program that makes available didactic lectures, group and individual sessions, bibliotherapy, films and opportunities for directed overnight sexual exploration within the hospital. We advocate that sex therapy be integrated into comprehensive rehabilitation programs along with physical therapy occupational therapy, recreation therapy and psychotherapy as an integral and effective form of functional restoration for patients with major physical disabilities.

    Full Text Available Background: The pursuit of sexual pleasure is a key motivating factor in sexual activity. Many things can stand in the way of sexual orgasms and enjoyment, particularly among women. These are essential issues of sexual well-being and gender equality. Objective: This study presents long-term trends and determinants of female orgasms in Finland. The aim is to analyze the roles of factors such as the personal importance of orgasms, sexual desire, masturbation, clitoral and vaginal stimulation, sexual self-esteem, communication with partner, and partner’s sexual techniques. Design: In Finland, five national sex surveys that are based on random samples from the central population register have been conducted. They are representative of the total population within the age range of 18–54 years in 1971 (N=2,152, 18–74 years in 1992 (N=2,250, 18–81 years in 1999 (N=1,496, 18–74 years in 2007 (N=2,590, and 18–79 years in 2015 (N=2,150. Another dataset of 2,049 women in the age group of 18–70 years was collected in 2015 via a national Internet panel. Results: Contrary to expectations, women did not have orgasms that are more frequent by increasing their experience and practice of masturbation, or by experimenting with different partners in their lifetime. The keys to their more frequent orgasms lay in mental and relationship factors. These factors and capacities included orgasm importance, sexual desire, sexual self-esteem, and openness of sexual communication with partners. Women valued their partner’s orgasm more than their own. In addition, positive determinants were the ability to concentrate, mutual sexual initiations, and partner’s good sexual techniques. A relationship that felt good and worked well emotionally, and where sex was approached openly and appreciatively, promoted orgasms.

    Researchers have given significant attention to abstinence among adolescents, but far less is known about purposeful avoidance of sexual activity (and relationship involvement). Typically, it is assumed that, once adolescents have initiated sexual activity, they will thereafter engage in sexual activity if given the opportunity. However, it is unclear whether that is true as some research indicates that many adolescents engage in sexual activity intermittently. Sexually experienced adolescents may purposefully avoid engaging in sexual activity for a period of time and, if so, this has implications for understanding their sexual decision-making. We used a mixed methods approach to investigate sexually experienced adolescents' decisions to purposefully avoid further sexual activity and/or romantic relationships with a focus on how common these decisions are and factors influencing them. Participants were 411 (56 % female) adolescents (16-21 years old) who completed an on-line survey that assessed reasons for each type of avoidance, religiosity, sexual esteem, sexual distress, sexual coercion, and dysfunctional sexual beliefs. Overall, 27 % of participants had engaged in sexual avoidance and 47 % had engaged in romantic avoidance. Significantly more female than male adolescents reported sexual and romantic avoidance. Adolescents' reasons for sexual avoidance included: lack of sexual pleasure or enjoyment, relationship reasons, negative emotions, values, fear of negative outcomes, negative physical experience, and other priorities. Reasons for romantic avoidance included: effects of previous relationship, not interested in commitment, wrong time, other priorities, negative emotions, no one was good enough, and sexual concerns. Logistical regressions were used to assess associations between age, religiosity, sexual esteem, sexual distress, experience of sexual coercion, and dysfunctional sexual beliefs and having engaged in romantic and/or sexual avoidance.

    Sexual functioning is important to assess in patients with psychiatric illness as both the condition and associated treatment may contribute to sexual dysfunction (SD). Antidepressant medications, mood stabilizers, antipsychotics, and antianxiety agents may be associated with SD related to drug mechanism of action. Sexual adverse effects may be related to genetic risk factors, impact on neurotransmitters and hormones, and psychological elements. Effective strategies to manage medication-induced sexual dysfunction are initial choice of a drug unlikely to cause SD, switching to a different medication, and adding an antidote to reverse SD. Appropriate interventions should be determined on a clinical case-by-case basis.

    1986-05-01

    The physiology of the normal sexual response, epidemiology of sexual dysfunction, and the pharmacologic mechanisms involved in antihypertensive- and antipsychotic-induced problems with sexual function are discussed, with recommendations for patient management. The physiologic mechanisms involved in the normal sexual response include neurogenic, psychogenic, vascular, and hormonal factors that are coordinated by centers in the hypothalamus, limbic system, and cerebral cortex. Sexual dysfunction is frequently attributed to antihypertensive and antipsychotic agents and is a cause of noncompliance. Drug-induced effects include diminished libido, delayed orgasm, ejaculatory disturbances, gynecomastia, impotence, and priapism. The pharmacologic mechanisms proposed to account for these adverse effects include adrenergic inhibition, adrenergic-receptor blockade, anticholinergic properties, and endocrine and sedative effects. The most frequently reported adverse effect on sexual function with the antihypertensive agents is impotence. It is seen most often with methyldopa, guanethidine, clonidine, and propranolol. In contrast, the most common adverse effect on sexual function with the antipsychotic agents involves ejaculatory disturbances. Thioridazine, with its potent anticholinergic and alpha-blocking properties, is cited most often. Drug-induced sexual dysfunction may be alleviated by switching to agents with dissimilar mechanisms to alter the observed adverse effect while maintaining adequate control of the patient's disease state.

    Delay consideration has been a majorissue in design and test of high performance digital circuits. Theassumption of input signal change occurring only when all internal nodesare stable restricts the increase of clock frequency. It is no longertrue for wave pipelining circuits. However, previous logical delaymodels are based on the assumption. In addition, the stable time of arobust delay test generally depends on the longest sensitizable pathdelay. Thus, a new delay model is desirable. This paper explores thenecessity first. Then, Boolean process to analytically describe thelogical and timing behavior of a digital circuit is reviewed. Theconcept of sensitization is redefined precisely in this paper. Based onthe new concept of sensitization, an analytical delay model isintroduced. As a result, many untestable delay faults under thelogical delay model can be tested if the output waveforms can be sampledat more time points. The longest sensitizable path length is computedfor circuit design and delay test.

  7. Relationship between short-term sexual strategies and sexual jealousy.

    2005-02-01

    In a classic study, Buss, Larson, Westen, and Semmelroth reported that men were more distressed by the thought of a partner's sexual infidelity (sexual jealousy) and women were more distressed by the thought of a partner's emotional infidelity (emotional jealousy). Initially, Buss and his associates explained these results by suggesting that men are concerned about uncertainty of paternity, that is, the possibility of raising another man's child while believing the child is their own. However, later they explained the results in terms of men's preference for short-term sexual strategies. The purpose of this research was to test the explanation of short-term sexual strategies. Men and women subjects were instructed to imagine themselves in a relationship which was either short-term (primarily sexual) or long-term (involving commitment) and then respond to Buss's jealousy items. It was hypothesized that, when both men and women imagined a short-term relationship, they would be more threatened by a partner's sexual infidelity, and, when they imagined a long-term relationship, they would be more threatened by a partner's emotional infidelity. Support was found for this hypothesis.

    To investigate unobtrusively how individuals experience sexual bondage, we analyzed all messages about sexual bondage (N = 514) mailed to an international computerized discussion group on sexual bondage in 1990. The most frequent individual experience reported (n = 60) was playful use of bondage to explore new areas of sexual pleasure. Other frequent experiences were the exchange of power, intensified sexual pleasure, and tactile stimulation and bodily sensations. Preference for the dominant-initiator role was expressed in 71% of the messages by male heterosexuals, 11% of the messages by heterosexual females, and 12% of the messages by homosexual males. Preference for the submissive-recipient role was expressed in 29% of the messages by heterosexual males, 89% by heterosexual females, and 88% by homosexual males. In 33% of messages subjects stated that sexual bondage occurred simultaneously with sadomasochism or was perceived as part of it.

    2008-03-01

    Sexual dysfunction in women with epilepsy (WWE) is an important comorbidity. A significant minority of WWE have markedly decreased sexual interest and it appears that orgasmic dysfunction occurs more frequently in WWE than in control women. Enzyme-inducing antiepileptic drugs can adversely affect sexual functioning by decreasing bioactive testosterone levels. Temporal lobe epilepsy of right-sided versus left-sided origin may also be a risk factor for sexual dysfunction. In addition to these factors, emerging evidence suggests that the serotonin transporter protein is related to temporal lobe epilepsy and it is postulated that this transporter may play a role in altered sexual functioning in epilepsy, perhaps through the serotonergic effects of antiepileptic drugs (AEDs). Strategies for modifying the contributors to sexual dysfunction in WWE will be discussed as well as the role of the neurologist in initiating management of this challenging comorbidity.

    2013-07-01

    This article is part of a Special Issue "Puberty and Adolescence". Sexuality emerges as a major developmental element of puberty and the adolescent years that follow. However, connecting the sexuality that emerges with puberty and elements of adult sexuality is difficult because much adolescent sexuality research addresses the transition to partnered sexual behaviors (primarily coitus) and consequences such as unplanned pregnancy and sexually transmitted infections. This review proposes a framework of an expanded understanding of puberty and adolescent sexuality from the perspective of four hallmarks of adult sexuality: sexual desire; sexual arousal; sexual behaviors; and, sexual function. This approach thus addresses important gaps in understanding of the ontogeny of sex and the continuum of sexuality development from adolescence through the adult lifespan.

    New digital media (e.g., the Internet, text messaging, and social networking sites [SNS]) have dramatically altered the communication landscape, especially for youth. These communication platforms present new tools for engaging youth in sexual health promotion and risk reduction. We searched eight public databases across multiple disciplines for all peer-reviewed studies published between January 2000 and May 2011 that empirically evaluated the impact of digital media-based interventions on the sexual health knowledge, attitudes, and/or behaviors of adolescents aged 13-24 years. Of 942 abstracts, 10 met inclusion criteria. Seven studies were conducted in the United States. Eight described Web-based interventions, one used mobile phones, and one was conducted on an SNS. Two studies significantly delayed initiation of sex, and one was successful in encouraging users of an SNS to remove sex references from their public profile. Seven interventions significantly influenced psychosocial outcomes such as condom self-efficacy and abstinence attitudes, but at times the results were in directions unexpected by the study authors. Six studies increased knowledge of HIV, sexually transmitted infections, or pregnancy. This area of research is emerging and rapidly changing. More data from controlled studies with longer (>1 year) follow-up and measurement of behavioral outcomes will provide a more robust evidence base from which to judge the effectiveness of new digital media in changing adolescent sexual behavior.

    The assessment of links between traumatic events of sexual nature recollected from the past and patients' later functioning in sexual life and relationships. Comorbidity of memories of traumatic sexual events from childhood and adolescence in patients with the features of their current partner relationships was analysed on the basis of Live Inventory completed by 2,582 women and 1,347 men, undergoing treatment between the years 1980-2002, before they were admitted to a day ward of neurotic disorder department. The existence of numerous significant links was observed e.g. the information regarding incest or incest attempt experience was related with a significant risk ofa sexual life assessment as completely dissatisfying in women (OR = 2.71) and almost completely dissatisfying in men (OR = 2.38). Sexual initiation by rape was related with women's more frequent incidence of getting married as a result of social pressure (OR = 3.77) and a feeling of hatred towards a partner (OR = 5.41). Men and women who considered themselves completely sexually uneducated (before the age of 18) assessed their sexual life as completely dissatisfying (OR = 2.48 and OR = 2.07), which was similar to men who would get punished for masturbation or sexual plays by their guardians (OR=2.68). Traumatic events and circumstances relating to sexuality, indicated in the questionnaire interview, turned out to be connected with the risk of dysfunctions in a sexual life and relationship. The traumas included, among others, rape during initiation, early initiation, incest, but also unfavourable circumstances of less traumatic nature such as a lack of sexual education, punishment for masturbation, "mostly undesired initiation". Their likely effects were rooted in relationship dysfunctions: reasons for their formation, power division, instability, problems with resolving conflicts and, most of all, sexual life dysfunctions. The results were obtained on the basis of simple questionnaire questions

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

    Lehtonen, Jussi; Schmidt, Daniel J; Heubel, Katja; Kokko, Hanna

    2013-05-01

    Sexual parasites offer unique insights into asexual and sexual reproduction. They mate with a 'host' whose genetic contribution is discarded either immediately (in androgenesis or gynogenesis) or after a delay of one generation (in hybridogenesis). The discarded genome can be maternal or paternal, implying that not only females but also males can reproduce asexually. The resulting lineages are often older than ecological or evolutionary theory predicts. Sexual parasites have links to a diverse set of concepts: selfish genetic elements, degradation of clonal genomes, evolution of sex, mate-choice theory, and host-parasite dynamics. We discuss the different sexually parasitic systems in both hermaphrodites and gonochoristic organisms, emphasizing their similarities and differences in ecological and evolutionary settings.

    Full Text Available Carbon monoxide poisoning is a major cause of death following attempted suicide and accidental exposures. Although clinical presentation depends on the duration and the intensity of exposure, the assessment of the severity of intoxication is difficult. A small percentage of patients who show complete initial recovery may develop delayed neurological deficits. Delayed encephalopathy after acute carbon monoxide poisoning is a rare and poor prognosis neurologic disorders and there is no specific treatment. We present a case with early onset of delayed encephalopathy after acute carbon monoxide poisoning with typical cranial imaging findings in a child with atypical history and clinical presentation.

  1. Rethinking Sexual Citizenship.

    Science.gov (United States)

    Richardson, Diane

    2017-04-01

    Over the last two decades sexuality has emerged as a key theme in debates about citizenship, leading to the development of the concept of sexual citizenship. This article reviews this literature and identifies four main areas of critical framing: work that contests the significance of sexuality to citizenship; critiques that focus on the possibilities and limitations of mobilising the language of citizenship in sexual politics; analyses of sexual citizenship in relation to nationalisms and border making; and literature that critically examines western constructions of sexuality and sexual politics underpinning understandings of sexual citizenship. In order to progress the field theoretically, the article seeks to extend critiques of sexual citizenship focusing on two key aspects of its construction: the sexual citizen-subject and spaces of sexual citizenship. It argues for a critical rethink that encompasses a de-centring of a 'western-centric' focus in order to advance understandings of how sexual citizenship operates both in the Global North and South.

    Damasceno, Fabio; Skinner, Gabriela O; Cordeiro, Júlia F; Ferraz, Marcos R; Almeida, Olga M M S

    2008-06-09

    Paradoxical sleep deprivation (PSD) produces alterations in dopaminergic systems and also modifies sexual behavior. In this work we evaluated PSD effects on the sexual response and tyrosine hydroxylase (TH) expression in dopaminergic pathways related to sexual behavior of naive and sexual experienced rats. Male Wistar rats had their sexual behavior evaluated in 6 copulatory tests, with a 4 days interval. In these tests, the animals interacted with a receptive female and parameters that compose each component of the male sexual reply (initiation, arousal and ejaculation) were evaluated. After the 5th test, the animals were randomly divided in 2 groups, control and PSD, and 96 h later they were submitted to the last copulatory test. PSD facilitated the excitatory and the ejaculatory component, increasing the copulatory efficiency. In addition, reduced mount frequency and ejaculation latency were observed. The temporal patterning of the sexual behavior was modified, with reduction in the number of mount bouts. PSD per se was not able to modify TH levels, but in PSD sexual trained rats, an increase in the number of TH-immunoreactive cellular bodies in all dopaminergic areas evaluated was detected. Our data suggest that PSD facilitates the sexual response and this facilitation combined to sexual training could be the consequence of increased TH levels in dopaminergic pathways related to sexual reply.

    In most instances, delayed emergence from anesthesia is attributed to residual anesthetic or analgesic medications. However, delayed emergence can be secondary to unusual causes and present diagnostic dilemmas. Data from clinical studies is scarce and most available published material is comprised of case reports. In this review, we summarize and discuss less common and difficult to diagnose reasons for delayed emergence and present cases from our own experience or reference published case reports/case series. The goal is to draw attention to less common reasons for delayed emergence, identify patient populations that are potentially at risk and to help anesthesiologists identifying a possible cause why their patient is slow to wake up.

    Full Text Available This month two general practitioners (GPs describe their approach to sexual health consultations.The issue of a sexually active adolescent demonstrates some differences in legislation pertaining tothe requirement to involve the authorities, although in essence the young person can expect thesame response from these practitioners in two different health care systems. On the other hand apatient at risk of sexually transmitted infections is more likely to be referred to a specialistGenitourinary clinic in the UK although the protocols for screening and education are largely similar.Equally patients who are HIV positive can expect to receive the bulk of their care from specialistclinics in both countries.Midwives are the main stay of antenatal services in Australia and the UK with general practitionersminimally involved in routine cases. Also home births are a negigible proportion of all deliveries ineither country. When patients opt for a home birth our authors expressed the view that GPsgenerally do not have the skills or experience to be the main health professional in attendance.Therefore such births are primarily managed by midwives as the key health care professional. Thefocus of General practitioners is primarily to ensure that the patient is making an informed decisionabout delivering her baby at home. The GP is therefore still in an influential position to assist thewoman in making a decision about where to give birth. As a point of difference in Australia a homebirth would result in out of pocket expences for the mother.The views expressed below are those of the authors and do not necessarily reflect health policy orpractice elsewhere in their countries. However we believe they offer an interesting perspective ontheir health care systems and commend the article to our readers.Please

    Some studies reported that {sup 99m}Tc-MIBI may redistribute in ischaemic myocardium and this phenomenon may have potential role for better assessment of viability by delayed {sup 99m}Tc-MIBI imaging. Some studies also suggested that infusion of low dose dobutamine during delayed imaging may enhance the value of {sup 99m}Tc-MIBI imaging for evaluation of viability. The aim of this study is to determine whether the observed changes of perfusion defects on delayed images are caused by early radiotracer redistribution or as a result of reversal partial volume effect secondary to inotropic stimulation. Patients, methods: 89 patients with angiographically proven coronary artery disease (CAD) were enrolled in this randomized clinical trial study. In all cases, gated-SPECT images were obtained 60 minutes after stress with dipyridamole injection. Subsequently the patients were randomly allocated in two groups and the second imaging was performed at 120{sup th} minute during low dose dobutamine (dobutamine group; 45 cases) or placebo infusion (placebo group; 44 cases). Difference between summed stress score of the first (SSS{sub 1}) and second (SSS{sub 2}) stress images ({delta}SSS) was considered as a marker of reversibility in single-injection double-acquisition (SIDA) protocol. Also summed difference score (SDS) was recorded as a marker of reversibility in standard stress/rest, double-injection double-acquisition (DIDA) protocol. {delta}SSS of the two studied groups were compared. Also the correlation and agreement between {delta}SSS and SDS were analyzed. Results: A significant difference was found between SSS{sub 1} (median 15, range 0-48) and SSS{sub 2} (median 11, range 0-42) in total patients (p < 0.0001). A significant correlation was noted between {delta}SSS and SDS in dobutamine group (r = 0.58, p = 0.002) as well as in placebo group (r = 0.57, p < 0.0001). Considering DIDA protocol as a standard reference method, the influence of dobutamine infusion was not

    2016-01-01

    We investigated the sexual values, attitudes, and behaviors of 30 Somali female refugees living in a large metropolitan area of Minnesota by collecting exploratory sexual health information based on the components of the sexual health model-components posited to be essential aspects of healthy human sexuality. A Somali-born bilingual interviewer conducted the semistructured interviews in English or Somali; 22 participants chose to be interviewed in Somali. Interviews were translated, transcribed, and analyzed using descriptive statistics and thematic analyses. Our study findings highlighted a sexually conservative culture that values sexual intimacy, female and male sexual pleasure, and privacy in marriage; vaginal sexual intercourse as the only sanctioned sexual behavior; and the importance of Islamic religion in guiding sexual practices. Findings related to human immunodeficiency virus (HIV) revealed HIV testing at immigration, mixed attitudes toward condom use, and moderate knowledge about HIV transmission modes. Female genital cutting (FGC) was a pervasive factor affecting sexual functioning in Somali women, with attitudes about the controversial practice in transition. We recommend that health professionals take the initiative to discuss sexual health care and safer sex, sexual behaviors/functioning, and likely challenges to sexual health with Somali women--as they may be unlikely to broach these subjects without permission and considerable encouragement.

    1976-08-01

    Sexual excitement depends on a scenario the person to be aroused has been writing since childhood. The story is an adventure, an autobiography disguised as fiction, in which the hero/heroine hides crucial intrapsychic conflicts, mysteries, screen memories of actual traumatic events and the resolution of these elements into a happy ending, best celebrated by orgasm. The function of the fantasy is to take these painful experiences and convert them to pleasure-triumph. In order to sharpen excitement-the vibration between the fear of original traumas repeating and the hope of a pleasurable conclusion this time-one introduces into the story elements of risk (approximations of the trauma) meant to prevent boredom and safety factors (sub-limnal signals to the storyteller that the risk are not truly dangerous). Sexual fantasy can be studied by means of a person's daydreams (including those chosen in magazines, books, plays, television, movies, and outright pornography), masturbatory behavior, object choice, foreplay, techniques of intercourse, or postcoital behavior.

    To assess the sexual function of young women with spina bifida and myelomeningocele and to determine the factors influencing their sexual function. A postal cross-sectional study using a self-administered questionnaire was performed in 44 women, mean age 27.66 ± 5.89 years, with spina bifida and myelomeningocele. The questionnaire included the Brief Index of Sexual Functioning for Women and questions about voiding mode, urinary symptoms, socioeconomic status, education level, lifestyle, and partnership. In parallel, data were also collected from the paediatric surgery records of patients who returned the questionnaire. The response rate was 56.8% (25/44). All domains of female sexual function (thoughts/desires, arousal, frequency of sexual activity, receptivity/initiation, pleasure/orgasm, relationship satisfaction) were altered. Urinary incontinence was likely to be the main factor responsible for altered sexual function and was associated with lower thoughts/desires, arousal, and receptivity/initiation scores. Wearing pads also constituted a limitation to achieving intimacy. Young myelomeningocele women report poor sexual functioning. The presence of urinary incontinence is associated with lower thoughts/desire, arousal, and receptivity/initiation. Copyright © 2013 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

    2013-11-01

    Perfectionism is a multidimensional personality characteristic that can affect all areas of life. This article presents the first systematic investigation of multidimensional perfectionism in the domain of sexuality exploring the unique relationships that different forms of sexual perfectionism show with positive and negative aspects of sexuality. A sample of 272 university students (52 male, 220 female) completed measures of four forms of sexual perfectionism: self-oriented, partner-oriented, partner-prescribed, and socially prescribed. In addition, they completed measures of sexual esteem, sexual self-efficacy, sexual optimism, sex life satisfaction (capturing positive aspects of sexuality) and sexual problem self-blame, sexual anxiety, sexual depression, and negative sexual perfectionism cognitions during sex (capturing negative aspects). Results showed unique patterns of relationships for the four forms of sexual perfectionism, suggesting that partner-prescribed and socially prescribed sexual perfectionism are maladaptive forms of sexual perfectionism associated with negative aspects of sexuality whereas self-oriented and partner-oriented sexual perfectionism emerged as ambivalent forms associated with positive and negative aspects.

    Full Text Available Introduction In contrast to animal species in which linear relationships exist between hormonal status and sexual behaviour sexuality in human population is not determined so simply by the level of sexual steroids. The article analyses female sexuality in the light of hormonal status. Administration of sexual steroids during pregnancy and sexual differentiation High doses of gestagens, especially those with high androgen activity, widely used against miscarriages may lead to tomboys, but without differences in sexual orientation. However, it has been observed that the frequency of bisexual and lesbian women is higher in women with congenital adrenogenital syndrome. Hormones sexual desire and sexuality during menstrual cycle It has been established that sexual desire, autoeroticism and sexual fantasies in women depend on androgen levels. There are a lot of reports claiming that sexual desire varies during the menstrual cycle. Hormonal contraception and sexuality Most patients using birth control pills present with decreased libido. But, there are reports that progestagens with antiandrogenic effect in contraceptive pills do not affect sexual desire. Hormonal changes in peri- and postmenopausal period and sexuality Decreased levels of estrogen and testosterone in older women are associated with decreased libido, sensitivity and erotic stimuli. Sexuality and hormone replacement therapy Hormonal therapy with estrogen is efficient in reference to genital atrophy, but not to sexual desire. Really increased libido is achieved using androgens. Also, therapy with dehydroepiandrosterone (DHEA and tibolone have positive effects on female libido. Conclusion Effect of sexual steroids on sexual sphere of women is very complex. The association between hormones and sexuality is multidimensional, as several hormones are important in regulation of sexual behaviour. Still, it should be pointed out that sexuality is in the domain of hormonal, emotional

  1. Early sexual experience as a factor in prostitution.

    Science.gov (United States)

    James, J; Meyerding, J

    1978-01-01

    Using the literature of the early sexual histories of "normal" women and two recent studies on the sexual histories of prostitutes, this article examines the pattern of early sexual experience among prostitutes and how it differs from that common to nonprostitute women. Some significant differences found between the samples of prostitutes and the samples of "normal" women were that the prostitute samples, on the whole, learned less about sex from parents and more from personal experiences, as children experienced more sexual advances by elders, were more victimized by incest, generally initiated sexual activity at a younger age, more often had no further relationship with their first coital partner, and experienced a higher incidence of rape. The analysis of these data on early sexual history concentrates on abusive sexual experiences such as incest and rape. The authors believe that an abusive sexual self-identity relates to the development of an adult female pattern of occupational deviance such as prostitution.

  2. Acculturative Stress and Risky Sexual Behavior: The Roles of Sexual Compulsivity and Negative Affect.

    2016-01-01

    Recent syndemic models of sexual health disparities affecting racial/ethnic minorities have highlighted the role of discrimination. Yet no previous work has examined how acculturative stress (distress at the transition from one's original culture toward a new culture) associates with sexual HIV-risk behavior (SHRB). Work among other minority populations suggests sexual compulsivity (SC) may contribute to syndemic sexual health disparities as a means of coping with distress. With this in mind, the present study examined whether SC explained the relation between acculturative stress and SHRB. Separate analyses were conducted for males and females within a sample of 758 sexually initiated racial/ethnic minority college students. Among males and females, acculturative stress had an indirect effect on SHRB via SC. As the first study to examine SHRB in relation to acculturative stress, findings provide preliminary evidence that targeting SC among racial/ethnic minorities may help reduce sexual health disparities.

  3. Effects of 17α-ethynylestradiol on sexual differentiation and development of the African clawed frog (Xenopus laevis).

    Tompsett, Amber R; Wiseman, Steve; Higley, Eric; Pryce, Sara; Chang, Hong; Giesy, John P; Hecker, Markus

    2012-11-01

    Several studies have shown that exposure of amphibians, including the African clawed frog (Xenopus laevis), to potent estrogens at critical times during development results in feminization and/or demasculinization. However, genotyping of X. laevis has only recently become possible, so studies performed in the past were rarely able to make explicit linkages between genetic and phenotypic sex. Therefore, to further characterize this relationship, X. laevis tadpoles were exposed during development to 0.09, 0.84, or 8.81 μg/L 17α-ethynylestradiol (EE2), which is the estrogen analog commonly used in oral contraceptives. Exposure to all concentrations of EE2 tested resulted in significant delays in time to metamorphosis. Genotyping showed that genetic sex ratios were similar among treatments. However, morphological evaluation revealed that a significant number of individuals with a male genotype displayed mixed sex and abnormal phenotypes. Additionally, both genetic males and females exposed to EE2 exhibited greater presence of vitellogenin protein relative to the respective controls. Since estrogens function downstream of the initial molecular signals of sexual differentiation, it is likely that genetic male animals received mixed endogenous male and exogenous female signals that caused disordered sexual development. The production of vitellogenin was probably temporally separated and independent from primary effects on sexual differentiation, and might have contributed to delays in metamorphosis observed in individuals exposed to EE2.

    Portelli, C J

    1998-01-01

    Federal, state, and local laws in the US now govern almost every aspect of sexuality. This includes sexuality at the workplace, sexuality education, adolescent sexuality, access to sexuality information and sexually explicit materials, sexual orientation, and sexually transmitted disease(STD)/HIV transmission. Almost 33% of the US Supreme Court's docket this past term concerned sexuality issues. In contrast to 50 years ago, when sexuality law was confined to the criminal arena, contemporary "sex crimes" primarily relate to nonconsensual and exploitative behaviors. It is time for lawmakers, judges, lawyers, policy analysts, lobbyists, and advocates to realize they cannot legislate or litigate how, when, or why people fall in love. Rather, the role of the law should be to create and preserve models of justice and equality that seek to preserve one's individual rights to privacy and freedom to choose in matters related to one's sexuality. This includes free access to age-appropriate sexuality information, the right to marriage and children regardless of sexual orientation, comprehensive sexuality education that encompasses information about avoiding unwanted pregnancies and HIV/STDs, access to contraception and abortion, protection from sexually abusive or exploitative relationships, and access to sexual health care.

    Proeve, Michael; Howells, Kevin

    2002-12-01

    In this article, the authors build on previous discussions of the possible role of shame and guilt in sexual offending. They review the general psychological literature on shame and guilt and conclude that the distinction between internal and external shame is an important one in considering sexual offenders. The effects of shame and guilt on victim empathy and relapse are discussed, and it is proposed that the phenomena of shame and guilt have implications for treatment beyond those identified in previous studies. Shame is a salient feature in the initial presentation of many sexual offenders against children. Furthermore, aspects of the treatment of sexual offenders can be characterized as a shift from shame toward guilt. Implications of shame and guilt for treatment of sexual offenders are described.

  12. A dual physiological character for sexual function: libido and sexual pheromones.

    Science.gov (United States)

    Motofei, Ion G

    2009-12-01

    Human sexual response is a complex function involving many cerebral, spinal and peripheral aspects; the last are relatively known and benefit from good pharmacological control, as in the case of erectile dysfunction. Spinal cord sexual reflexes also have a good theoretical and experimental description. There is minimal understanding of the cerebral sexual processes (libido, sexual arousal, orgasm). The initial perspective was that the cerebral areas implied in sexuality exert descending stimulatory and inhibitory influences on spinal cord sexual centres/reflexes. This was a wrong supposition, which inhibited progress in this subject, with a considerable impact on a subject's individual and social life. A new approach to sexual function arises from the idea that simple neurological structures can support only simple functions, while a more complex function requires correspondingly complex anatomical structures. For this reason the spinal cord would not be able to realise the integration of multiple (spinal and psychosensorial) stimuli into a unique and coherent ejaculation response. Consequently, all mechanisms implied in human sexuality would be cerebral processes, ejaculation reflexes ascending in evolution to the cerebral level. This new evolutionary concept was developed after 2001 in five distinct articles on the cerebral duality of sexual arousal, sexual hormones, ejaculation and serotonergic receptors. During this period other published results suggested a possible cerebral duality for sexual pheromones and libido in humans. All these dual physiological aspects are integrated in this review into one neurophysiological model, thus trying to further develop the new concepts of sexual function and perhaps relational behaviour. In conclusion, ejaculation is a dual cerebral process with arousal sensation (hormonally modulated) and libido perception (pheromonally modulated) as the afferent part. Two neurophysiological axes could exist in both men and women. In this

    This paper deals with three major questions: (1) What are the sexual norms defined by the sacred texts (Koran and Sunna)? (2) What are the sexual practices currently observed among Moslems? (3) To which extent are current sexual practices of Moslems dissociated from Islamic sexual norms? Sexual standards in Islam are paradoxical: on the one hand, they allow and actually are an enticement to the exercise of sexuality but, on the other hand, they discriminate between male and female sexuality, between marital and pre- or extramarital sexuality, and between heterosexuality and homosexuality. Men are given more rights with regard to the expression of their sexuality; women are forbidden to have extramarital sex (with their slaves) and both genders to have homosexual relationships. The combination of these paradoxical standards with modernisation leads to the current back and forth swing of sexual practices between repression and openness. Partial modernisation leads to greater sexual tolerance. But restrictive sexual standards have gathered strength and have become idealised as a result of the current radicalisation of Islam. This swing of the pendulum between repression and openness is illustrated by phenomena such as public harassment, premarital sexuality, female pleasure, prostitution, and homosexuality. Currently, Islam is not any more the only reference which provides guidance concerning sexual practices but secularisation of sexual laws is still politically unthinkable today. So the only solution is to achieve reform in the name of Islam, through the reinterpretation of repressive holy texts.

    Gravitational time delays, observed in strong lens systems where the variable background source is multiply-imaged by a massive galaxy in the foreground, provide direct measurements of cosmological distance that are very complementary to other cosmographic probes. The success of the technique depends on the availability and size of a suitable sample of lensed quasars or supernovae, precise measurements of the time delays, accurate modeling of the gravitational potential of the main deflector,...

    The aim of this study was to describe some characteristics of vaginal, anal and oral sexual behavior in Spanish adolescents. It was a cross-sectional descriptive population study conducted using a probabilistic sample survey. The sample was composed of 4,612 male and female adolescents, of whom 1,686 reported having penetrative sexual experience. Sample size was established with a 97% confidence level and a 3% estimation error. Data collection took place in secondary education schools. Mean age of vaginal sex initiation was 15 years. Compared to females, males reported an earlier age of anal and oral sex initiation and a larger number of vaginal and anal sexual partners. Males also reported a higher frequency of penetrative sexual relations under the influence of alcohol or other drugs. A higher percentage of females than males reported not using a condom in their first anal sexual experience. This study provides a current overview of the sexual behavior of adolescents that can be useful for the design of future programs aimed at preventing HIV and sexually transmitted infections (STIs).

    There is a need for state-of-the-art information in the area of sexually transmitted infections (STIs) in relation to sexual function. There are an estimated 60 million people living with and 340 million with treatable STIs. Surveys show sexual problems to be as high as 35% for men and 55% for women; however, there is little research directly assessing relationships between infection and sexual function. To show that STIs are associated with (and may cause) sexual dysfunction. Conversely, sexual dysfunction can increase patients' risk of STI acquisition. In men, erectile dysfunction (ED) associated with condom use may lead to unsafe sexual practices and, hence, STI acquisition. The role of various therapies including phosphodiesterase type 5 inhibitors in the treatment of ED in positive men taking social drugs will be explored. To provide state-of-the-art knowledge concerning sexual function and STIs, representing the opinions of five experts from four countries developed in a consensus process and encompassing a detailed literature review over a 2-year period. Expert opinion was based on the grading of evidence-based medical literature, widespread internal committee discussion, public presentation, and debate. This article highlights major factors causing the spread of STIs and suggests management interventions to prevent further spread of HIV/STIs, focusing on the juxtaposition between STIs and sexual functioning. Women's unique vulnerabilities to HIV/STIs (biological and physiological issues, gender-based violence, gender inequity) and their impact on women's sexual function are reviewed. Similarly, men's unique vulnerabilities to HIV/STIs including condom use, disclosure, voluntary counseling and testing, multiple concurrent sexual partners, and recreational drug use--particularly in homosexual men--are explored, as is the association of prostatitis and sexual function. Lastly, the article reviews the relationship between circumcision and sexual dysfunction. A

    Sexual problems are common during pregnancy, but the proportion of pregnant women who experience sexual distress is unknown. In non-pregnant samples, sexual distress is associated with lower sexual and relationship satisfaction. To identify the proportion of women experiencing sexual distress during pregnancy and to compare the sexual and relationship satisfaction of women who report sexual distress during pregnancy with that of women without distress. Two-hundred sixty-one pregnant women completed a cross-sectional online survey. Women completed validated measurements of sexual functioning (Female Sexual Function Index; score relationship satisfaction (Couples Satisfaction Index). Overall, 42% of women met the clinical cutoff for sexual distress. Of sexually active women (n = 230), 26% reported concurrent sexual problems and distress and 14% reported sexual distress in the absence of sexual problems. Sexual distress and/or problems in sexual functioning were linked to lower sexual and relationship satisfaction compared with pregnant women with lower sexual distress and fewer sexual problems. Sexual distress is common during pregnancy and associated with lower sexual and relationship satisfaction. Health care providers should ask pregnant women about feelings of sexual distress. Identifying pregnant women who experience sexual distress and referring them to appropriate resources could help minimize sexual and relationship problems during pregnancy. Vannier SA, Rosen NO.

    Combined oral contraceptive pills (COCs) remain one of the most popular forms of contraception to prevent unwanted pregnancy in women. While it is known that COCs can cause sexual dysfunction in women, there is currently no recommendation to screen for sexual function before and after initiation of COCs. We propose that, based on the evidence available, assessment of sexual function should be done at initiation of COCs, as well as at regular intervals thereafter. This would allow COC-related sexual dysfunction to be managed early, such as by switching the patient to newer-generation COCs or other forms of contraception.

    Full Text Available This paper summarizes our research to date on sexual sadism. Our initial review of the literature revealed confusion over diagnostic criteria. Our first empirical study showed that experienced forensic psychiatrists did not accurately employ many of the important diagnostic criteria while our second study demonstrated that internationally-renowned forensic psychiatrists could not reliably apply the diagnosis. On the basis of these observations we developed a Sexual Sadism Scale that we are now in the process of evaluating.

    This study tested the Theory of Reasoned Action to examine the prediction of early sexual behavior among African American young teen girls. Baseline data from a longitudinal randomized clinical trial were used. Between 2001 and 2005, 198 middle-school girls aged 11 to 14 years were recruited. As girls aged, they held more permissive attitudes toward engaging in early sexual behavior and had a higher intention to engage in early sexual behavior. Intention was a significant predictor to explain sexual behavior among the girls. There is a need to develop strategies that promote intention related to delay and prevention of early sexual behavior.

    Full Text Available Sexual activity is a multifaceted activity, involving complex interactions between the nervous system, the endocrine system, the vascular system and a variety of structures that are instrumental in sexual excitement, intercourse and satisfaction. Sexual function has three components i.e., desire, arousal and orgasm. Many sexual dysfunctions can be categorized according to the phase of sexual response that is affected. In actual clinical practice however, sexual desire, arousal and orgasmic difficulties more often than not coexist, suggesting an integration of phases. Sexual dysfunction can result from a wide variety of psychological and physiological causes including derangements in the levels of sex hormones and neurotrensmitters. This review deals with the biology of different phases of sexual function as well as implications of hormones and neurotransmitters in sexual dysfunction

    2010-08-01

    Despite indirect evidence linking narcissism to sexual aggression, studies directly examining this relationship have yielded inconsistent results. Likely contributing to such inconsistencies, prior research has used global measures of narcissism not sensitive to whether the components of narcissism are activated in sexual versus non-sexual domains. The current research avoided such problems by using a measure of sexual narcissism to predict sexual aggression. In a sample of 299 men and women, Study 1 validated the Sexual Narcissism Scale, a new sexuality research instrument with four subscales-Sexual Exploitation, Sexual Entitlement, Low Sexual Empathy, and Sexual Skill. Then, in a sample of 378 men, Study 2 demonstrated that sexual narcissism was associated with reports of the frequency of sexual aggression, three specific types of sexual aggression (unwanted sexual contact, sexual coercion, and attempted/completed rape), and the likelihood of future sexual aggression. Notably, global narcissism was unrelated to all indices of sexual aggression when sexual narcissism was controlled. That sexual narcissism outperformed global assessments of narcissism to account for variance in sexual aggression suggests that future research may benefit by examining whether sexual narcissism and other sexual-situation-specific measurements of personality can similarly provide a more valid test of the association between personality and other sexual behaviors and outcomes (e.g., contraceptive use, infidelity, sexual satisfaction).

    Research on multidimensional sexual perfectionism differentiates four forms: self-oriented, partner-oriented, partner-prescribed, and socially prescribed. Self-oriented sexual perfectionism reflects perfectionistic standards people apply to themselves as sexual partners; partner-oriented sexual perfectionism reflects perfectionistic standards people apply to their sexual partner; partner-prescribed sexual perfectionism reflects people's beliefs that their sexual partner imposes perfectionistic standards on them; and socially prescribed sexual perfectionism reflects people's beliefs that society imposes such standards on them. Previous studies found partner-prescribed and socially prescribed sexual perfectionism to be maladaptive forms of sexual perfectionism associated with a negative sexual self-concept and problematic sexual behaviors, but only examined cross-sectional relationships. The present article presents the first longitudinal study examining whether multidimensional sexual perfectionism predicts changes in sexual self-concept and sexual function over time. A total of 366 women aged 17-69 years completed measures of multidimensional sexual perfectionism, sexual esteem, sexual anxiety, sexual problem self-blame, and sexual function (cross-sectional data). Three to six months later, 164 of the women completed the same measures again (longitudinal data). Across analyses, partner-prescribed sexual perfectionism emerged as the most maladaptive form of sexual perfectionism. In the cross-sectional data, partner-prescribed sexual perfectionism showed positive relationships with sexual anxiety, sexual problem self-blame, and intercourse pain, and negative relationships with sexual esteem, desire, arousal, lubrication, and orgasmic function. In the longitudinal data, partner-prescribed sexual perfectionism predicted increases in sexual anxiety and decreases in sexual esteem, arousal, and lubrication over time. The findings suggest that partner-prescribed sexual

    Inappropriate sexual behavior, or sexually aggressive behavior, is a term which encompasses a variety of behaviors, including obscene gesturing, touching or hugging another person, exposing body parts or disrobing, and masturbating in public. Inappropriate sexual behavior often elicits feelings of anxiety, embarrassment, or unease in the caregiver and the result is often disruption in continuity of care for the patient. The cause of inappropriate sexual behavior varies among individuals and careful assessment of the etiology of the behavior is the first essential step in intervening. Nursing interventions focus upon providing opportunities for expression of appropriate sexual behavior while attempting to extinguish inappropriate sexual behavior.

    India is a vast country depicting wide social, cultural and sexual variations. Indian concept of sexuality has evolved over time and has been immensely influenced by various rulers and religions. Indian sexuality is manifested in our attire, behavior, recreation, literature, sculptures, scriptures, religion and sports. It has influenced the way we perceive our health, disease and device remedies for the same. In modern era, with rapid globalization the unique Indian sexuality is getting diffused. The time has come to rediscover ourselves in terms of sexuality to attain individual freedom and to reinvest our energy to social issues related to sexuality.

    Health care providers must recognize the specific challenges and rewards of providing services for adolescents. Quality care begins with the establishment of trust, respect, and confidentiality between the health care provider and the adolescent. Data suggest that the normal age for beginning puberty is decreasing, which has important clinical, educational, and social implications. The health care provider should be aware of the broad range of potential sexual behaviors involving adolescents, as well as the teen's acceptance of such behaviors, often dictated by age, gender, culture, and education. When providing gynecologic care to adolescent girls, the physician should not only provide contraception and screen for sexually transmitted diseases but should contribute to the development of the patient's sexual health. Especially when providing care for the younger teen, the health care provider must focus on involving a member of the family or another significant adult to provide needed support and guidance. Anticipatory guidance for parents should focus on assessing their parenting styles and promoting supervision. Although parents should strive to maintain open communication with their adolescents, they may not accurately estimate the sexual activity of and the sexual risk for their teenage children. Parents need to be encouraged to consider the implications of their own sexual behaviors. The provider should attempt to foster a comfortable environment in which youth may seek help and support for appropriate medical care while reserving the right to disclose their sexual identity when ready. Health care professionals cannot exclude heterosexual behavior on the basis that a young woman self-identifies as homosexual. Her reported sexual behaviors may not indicate her sexual orientation. Self-definition of sexual orientation is a dynamic process including factors such as fantasies, desires, and behaviors. Self-definition of sexual identity is affected by individual

    Recent studies have shown that adolescents have initiated their sex lives earlier and earlier, without, however, receiving consistent sex education. The objectives of this study were to analyze the sexual behavior of adolescent high school students and identify the habits of sexual health in sexually active adolescent high school students. An exploratory study was conducted with 680 adolescents, whose age ranged between 15 and 19 years. Results showed that most participants had not initiated their sex life; boys are those who most report having had sexual relations; not all the interviewed adolescents used condoms during sex; most adolescents do not practice sexual health surveillance. It is important for sexually active adolescents to receive health care and counseling. Health institutions and their workers must be proactive in trying to approach adolescents.

    2009-09-01

    Sexuality and sexual disorders of patients with psychoses are frequently neglected and under-investigated. The main purpose of the present study is to discuss the subjective experience of sexuality in patients with psychosis within the general psychodynamic and phenomenological understandings of psychotic states. The authors, both psychotherapists, dealing with patients with psychoses, reflected experiences from their clinical work with the help of the conceptual frameworks of psychodynamic and phenomenological psychiatry. Willingness and need of patients to talk about sexuality, non-specificity of frequencies and variety of sexual disorders in psychotic patients, difficulties in establishment of a stable (sexual) identity and the question of homosexuality, absence of sexual activities with others and feelings of guilt and inadequacy, masturbation with its functions, impulsive sexual acts or lack of sexual self-control, erotic delusions and erotic transference were the main findings, dominating the sexual sphere of these patients. All these manifestations of sexuality in patients with psychosis can be seen - as exposed in discussion - as consequences of a basic self-disorder (phenomenological perspective) or of difficulties in regulating closeness and distance (psychodynamic perspective). Reasons of avoidance of treatment of sexuality by the therapists of psychotic patients are discussed as well. Implications for dealing with sexuality issues in psychotherapy of patients with psychoses were drawn from the above findings in the last part of the article.

    The onset of menarche and age of first sexual experience have both lowered over the past century. Does the age of puberty influence the sexuality of the girl/young occidental woman? If so, to what degree? Besides, is the acquisition of reproductive function, regardless of age, a sign of sufficient maturity to engage in sexual activity? Studies show that early puberty, early sex, unprotected sexual intercourse in adolescence and number of sexual partners in early adulthood are closely related. These early sexual experiences could be stimulated by early drug use as well as by depressive disorders. The age of puberty has a real influence on sexuality but this link will be modulated by a number of social behavioral factors and it is not sustainable. The age of puberty is not a good indicator of maturity for teenage sexuality; early maturation and early sexual activity are usually associated with risky behaviors. However, other studies on the subject are required, including a consideration of the issues associated with delayed puberty, a subject virtually absent from the literature.

    Gravitational time delays, observed in strong lens systems where the variable background source is multiply-imaged by a massive galaxy in the foreground, provide direct measurements of cosmological distance that are very complementary to other cosmographic probes. The success of the technique depends on the availability and size of a suitable sample of lensed quasars or supernovae, precise measurements of the time delays, accurate modeling of the gravitational potential of the main deflector, and our ability to characterize the distribution of mass along the line of sight to the source. We review the progress made during the last 15 years, during which the first competitive cosmological inferences with time delays were made, and look ahead to the potential of significantly larger lens samples in the near future.

    Burns, K.

    A predictive model of delayed subsidence is discussed. A numerical implementation is tested on one of the best-described study areas, Allegheny County in Pennsylvania. In planning insurance of restitution measures, a predictive model is of value in estimating the magnitude of the problem and the size of long-term budgetary commitments. Contrary to active subsidence, which occurs concurrently with mining operations, or is completed within a few days following coal extraction, delayed subsidence may take many years to appear at the surface after coal mines are abandoned. There are two principal morphological types of delayed subsidence: troughs, which are shallow depressions, and sinks, which are steep-sided crown pits. Both types are damaging to surface structures, and a variety of methods were introduced to deal with the problem, ranging from subsidence insurance to site restitution.

    Full Text Available Abstract Background As other countries, Switzerland experiences a high or even rising incidence of HIV and sexually transmitted infections (STI among men who have sex with men (MSM. An outpatient clinic for gay men ("Checkpoint" was opened in 2006 in Zurich (Switzerland in order to provide sexual health services. The clinic provides counselling, testing, medical treatment and follow-up at one location under an "open-door-policy" and with a high level of personal continuity. We describe first experiences with the new service and report the characteristics of the population that utilized it. Methods During the 6-month evaluation period, individuals who requested counselling, testing or treatment were asked to participate in a survey at their first visit prior to the consultation. The instrument includes questions regarding personal data, reasons for presenting, sexual behaviour, and risk situations. Number and results of HIV/STI tests and treatments for STI were also recorded. Results During the evaluation period, 632 consultations were conducted and 247 patients were seen by the physician. 406 HIV tests were performed (3.4% positive. 402 men completed the entry survey (64% of all consultations. The majority of respondents had 4 and more partners during the last 12 months and engaged in either receptive, insertive or both forms of anal intercourse. More than half of the responders used drugs or alcohol to get to know other men or in conjunction with sexual activity (42% infrequently, 10% frequently and 0.5% used drugs always. The main reasons for requesting testing were a prior risk situation (46.3%, followed by routine screening without a prior risk situation (24.1% and clarification of HIV/STI status due to a new relationship (29.6%. A fifth of men that consulted the service had no history of prior tests for HIV or other STIs. Conclusion Since its first months of activity, the service achieved high levels of recognition, acceptance and demand in

    At least a third of women across reproductive ages experience low sexual desire and impaired arousal. There is increasing evidence that mindfulness, defined as non-judgmental present moment awareness, may improve women's sexual functioning. The goal of this study was to test the effectiveness of mindfulness-based therapy, either immediately or after a 3-month waiting period, in women seeking treatment for low sexual desire and arousal. Women participated in four 90-min group sessions that included mindfulness meditation, cognitive therapy, and education. A total of 117 women were assigned to either the immediate treatment (n = 68, mean age 40.8 yrs) or delayed treatment (n = 49, mean age 42.2 yrs) group, in which women had two pre-treatment baseline assessments followed by treatment. A total of 95 women completed assessments through to the 6-month follow-up period. Compared to the delayed treatment control group, treatment significantly improved sexual desire, sexual arousal, lubrication, sexual satisfaction, and overall sexual functioning. Sex-related distress significantly decreased in both conditions, regardless of treatment, as did orgasmic difficulties and depressive symptoms. Increases in mindfulness and a reduction in depressive symptoms predicted improvements in sexual desire. Mindfulness-based group therapy significantly improved sexual desire and other indices of sexual response, and should be considered in the treatment of women's sexual dysfunction.

    The paper proposed a terminal sliding mode control method for the delayed input system with uncertainties. Firstly, through the state transformation, the original system was transformed into the non-delayed controllable canonical form system. Then the paper designed a terminal sliding mode and terminal sliding control law with Lyapunov method for the transformed system. Through the method, the reaching time of the any initial state and the convergencing time to the equilibrium points are constrained in finite time. The simulation results show the validation of the method.

    Adverse childhood experiences (ACEs) have been linked to early sexual debut, which has been found to be associated with multiple adverse health outcomes. Sexual minorities and men tend to have earlier sexual debut compared to heterosexual populations and women, respectively. However, studies examining the association between ACEs and early sexual debut among men and sexual minorities are lacking. The aim of this study was to examine the sex and sexual orientation disparities in the association between ACEs and age at sexual debut. Data were obtained from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Logistic and linear regression models were used to obtain crude and adjusted estimates and 95% confidence intervals adjusting for age, race/ethnicity, income, education, insurance and marital status for the association between ACEs (neglect, physical/psychological abuse, sexual abuse, parental violence, and parental incarceration and psychopathology) and early sexual debut. Analyses were stratified by sex and sexual orientation. Larger effect estimates depicting the association between ACEs and sexual debut were seen for women compared to men, and among sexual minorities, particularly among men who have sex with men (MSM) and women who have sex with women (WSW), compared to heterosexuals. Sexual health education programs with a focus on delaying sexual debut among children and adolescents should also consider addressing ACEs, such as neglect, physical, psychological and sexual abuse, witnessing parental violence, and parental incarceration and psychopathology. Public health practitioners, researchers and sexual health education curriculum coordinators should consider these differences by sex and sexual orientation when designing these programs.

Logistic and linear regression model were used to obtain crude and adjusted estimates and 95% confidence intervals adjusting for age, race/ethnicity, income, education, insurance and marital status for the association between ACEs (neglect, physical/psychological abuse, sexual abuse, parental violence, and parental incarceration and psychopathology) and early sexual debut. Analyses were stratified by sex and sexual orientation. Larger effect estimates depicting the association between ACEs and sexual debut were seen for women compared to men, and among sexual minorities, particularly among men who have sex with men (MSM) and women who have sex with women (WSW), compared to heterosexuals. Sexual health education programs with a focus on delaying sexual debut among children and adolescents should also consider addressing ACEs, such as neglect, physical, psychological and sexual abuse, witnessing parental violence, and parental incarceration and psychopathology. Public health practitioners, researchers and sexual health education curriculum coordinators should consider these differences by sex and sexual orientation when designing these programs.

    Ohira, Toru

    2016-01-01

    We present here a system with collection of random walks relaying a signal in one dimension with a presence of a delay. We are interested in the time for a signal to travel from one end (start) to the other end (finish) of the lined group of random walkers. It is found that there is an optimal number of walkers for the signal to travel fastest if the delay is present. We discuss implications of this model and associated behaviors to physical and biological systems.

  6. Approximation of distributed delays

    Lu, Hao; Eberard, Damien; Simon, Jean-Pierre

    2010-01-01

    We address in this paper the approximation problem of distributed delays. Such elements are convolution operators with kernel having bounded support, and appear in the control of time-delay systems. From the rich literature on this topic, we propose a general methodology to achieve such an approximation. For this, we enclose the approximation problem in the graph topology, and work with the norm defined over the convolution Banach algebra. The class of rational approximates is described, and a constructive approximation is proposed. Analysis in time and frequency domains is provided. This methodology is illustrated on the stabilization control problem, for which simulations results show the effectiveness of the proposed methodology.

  7. "Talking about child sexual abuse would have helped me": Young people who sexually abused reflect on preventing harmful sexual behavior.

    2017-08-01

    Harmful sexual behavior carried out by children and young people accounts for about half of all child sexual abuse perpetration. The aim of this study was to draw on the insights of young people who had been sexually abusive to enhance the current prevention agenda. The study involved semi-structured interviews with 14 young people and six treatment-providing workers. Sampling was purposive and the young people had previously completed a treatment program for harmful sexual behaviour in Victoria, Australia. The young people were approached as experts based on their previous experience of engaging in harmful sexual behavior. At the same time, their past abusive behavior was not condoned or minimised. Constructivist Grounded Theory was used to analyse the qualitative data. Opportunities for preventing harmful sexual behavior were the focus of the interviews with young people and workers. The research identified three opportunities for prevention, which involved acting on behalf of children and young people to: reform their sexuality education; redress their victimization experiences; and help their management of pornography. These opportunities could inform the design of initiatives to enhance the prevention agenda. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Kansky, J

    1986-01-01

    The sexual adjustment of 31 Caucasian women, ages 30-62, widowed less than 14 months was assessed using a structural interview. The relationship between the frequencies of autostimulation, coitus, sexual desire and other selected variables was analyzed. Results showed that the sexual identity and experience of each individual widow; circumstances surrounding the death of the husband, particularly whether the death was sudden or delayed; the widow's age; overall sexual satisfaction and intimacy within the marriage, as opposed to ambivalence toward the relationship; and the degree and kind of attachment to the deceased spouse; seem to be significantly associated with the sexual desires and activities of widows during the first 14 months of bereavement.

    2010-01-01

    Full Text Available This paper results from an investigation on the discourse of female sexuality carried by women's magazines in the years 2005 and 2006. 'Claudia' and 'Mulher dia-a-dia' were the documents analyzed through a qualitative investigative approach. The data construction was undertaken through critical discourse analysis, and female sexuality was approached from a constructivist perspective. The main results showed that the discursive conventions present in the reports gave shape to dual positions on contemporary Western sexual dynamics, such as: adoption of symmetrical sexual practices versus continuation of asymmetrical sexual practices; female sexual autonomy versus female sexual dependency; activeness versus passiveness; female pleasure versus male pleasure. Thus, we argue that sexuality remains doubly informed by hegemonic standards in force within society.

    Aggarwal, Bimal; Bhalla, A K; Singh, Surjit

    2011-11-01

    This paper aimed to study sexual maturation of boys with juvenile rheumatoid arthritis (JRA) during adolescence. This study was carried out in the Department of Pediatrics, Advanced Pediatrics Center, Post Graduate Institute of Medical Education and Research, Chandigarh, India. A total of 70 boys (between 9 and 17 years of age) diagnosed as cases of JRA comprised the sample for this study. Every child was examined for the development of genitalia as per criteria given by Tanner (Growth at adolescence, 2nd edn, Blackwell, Oxford, 1962) at half-yearly age intervals. However, with regard to development of hair (pubic, axillary and facial) mere presence or absence was noted. Mean (±SD) age of attainment of different stages of genitalia development as well as for eruption of hair was ascertained amongst boys who entered puberty using conventional statistics. Initiation of genitalia development (i.e. appearance of G-2 stage) was earliest among boys with systemic onset JRA (10.8 ± 1.3 years). None of the boys with JRA could attain final stage (G-5) of genitalia development by the age of 17 years, as compared with normal Chandigarh boys who had attained this by 15.2 years. Age of appearance of axillary, pubic, and facial hair was also earlier in systemic onset type of disease as compared with those with pauciarticular and polyarticular JRA. The timing of initiation of sexual maturity in boys with different types of JRA remains variably affected, and appears to experience substantial delay in completion of puberty.

  18. Number of sexual partners and sexual assertiveness predict sexual victimization: do more partners equal more risk?

    Walker, Dave P; Messman-Moore, Terri L; Ward, Rose Marie

    2011-01-01

    In previous studies, number of sexual partners and sexual assertiveness were examined as independent risk factors for sexual victimization among college women. Using a sample of 335 college women, this study examined the interaction of number of sexual partners and sexual assertiveness on verbal sexual coercion and rape. Approximately 32% of the sample reported unwanted sexual intercourse, 6.9% (n = 23) experienced verbal sexual coercion, 17.9% (n = 60) experienced rape, and 7.2% (n = 24) experienced both. As number of sexual partners increased, instances of verbal sexual coercion increased for women low in relational sexual assertiveness but not for women high in relational sexual assertiveness. A similar relationship was not found for rape. Among women who experienced both verbal sexual coercion and rape, increases in number of partners in the context of low refusal and relational assertiveness were associated with increases in verbal sexual coercion and rape. Findings suggest sexual assertiveness is related to fewer experiences of sexual coercion.

    FIFO is perhaps the simplest scheduling discipline. For single-class FIFO, its delay guarantee performance has been extensively studied: The well-known results include a stochastic delay bound for $GI/GI/1$ by Kingman and a deterministic delay bound for $D/D/1$ by Cruz. However, for multiclass FIFO, few such results are available. To fill the gap, we prove delay bounds for multiclass FIFO in this work, considering both deterministic and stochastic cases. Specifically, delay bounds are present...

    A newly designed approach of simultaneous stabilization is given for linear discrete time-delay systems. The problem of stabilization for a collection of systems is discussed initially. Adequate condition are obtained in terms of linear matrix inequalities (LMIs) which are independent of time delays such that the resultant collection of discrete time-delay systems are stable with an upper bound of the quadratic performance index. Subsequently, controllers are designed such that the resultant closed-loop discrete time-delay systems are simultaneously stabilized with the upper bound of the quadratic performance index. Finally,a numerical example is given to illustrate the design method.

  8. Rethinking Sexual Citizenship

    Science.gov (United States)

    Richardson, Diane

    2016-01-01

    Over the last two decades sexuality has emerged as a key theme in debates about citizenship, leading to the development of the concept of sexual citizenship. This article reviews this literature and identifies four main areas of critical framing: work that contests the significance of sexuality to citizenship; critiques that focus on the possibilities and limitations of mobilising the language of citizenship in sexual politics; analyses of sexual citizenship in relation to nationalisms and border making; and literature that critically examines western constructions of sexuality and sexual politics underpinning understandings of sexual citizenship. In order to progress the field theoretically, the article seeks to extend critiques of sexual citizenship focusing on two key aspects of its construction: the sexual citizen-subject and spaces of sexual citizenship. It argues for a critical rethink that encompasses a de-centring of a ‘western-centric’ focus in order to advance understandings of how sexual citizenship operates both in the Global North and South.

  9. Does Sexual Satisfaction Change With Relationship Duration?

    Science.gov (United States)

    Schmiedeberg, Claudia; Schröder, Jette

    2016-01-01

    Despite a large body of empirical literature on sexual satisfaction, its development over the course of a relationship is still unclear. Only a small number of studies, most of which have relied on cross-sectional data of convenience samples, have explicitly focused on relationship duration, and empirical evidence is mixed. We analyzed how sexual satisfaction changes over the course of a relationship using three waves of the German Family Panel study (pairfam). We concentrated our analyses on young and middle-aged heterosexual individuals in committed relationships (N = 2,814) and applied fixed effects regression models, which have the advantage of estimations based on changes within individuals over time. We found a positive development of sexual satisfaction in the first year of a relationship, followed by a steady decline. This pattern persisted even when controlling for the frequency of intercourse, although the effects were, in part, mediated by intercourse frequency. We explained the non-linear effect of relationship duration on sexual satisfaction with an initial learning effect regarding partner-specific sexual skills, which is then outweighed by a decline in passion at later stages of a relationship. Moreover, we found significant effects for the control variables of health status, intimacy in couple communication, and conflict style, as expected. In contrast to past research, however, cohabitation and marriage were not found to play a role for sexual satisfaction in our data. Further research is required to deepen the understanding of the reasons why sexual satisfaction changes with relationship duration.

    Sleep disturbance and sexual dysfunction are common in menopause; however, the nature of their association is unclear. The present study aimed to determine whether sleep characteristics were associated with sexual activity and sexual satisfaction. Sexual function in the last year and sleep characteristics (past 4 wk) were assessed by self-report at baseline for 93,668 women age 50 to 79 years enrolled in the Women's Health Initiative (WHI) Observational Study (OS). Insomnia was measured using the validated WHI Insomnia Rating Scale. Sleep-disordered breathing (SDB) risk was assessed using questions adapted from the Berlin Questionnaire. Using multivariate logistic regression, we examined cross-sectional associations between sleep measures and two indicators of sexual function: partnered sexual activity and sexual satisfaction within the last year. Fifty-six percent overall reported being somewhat or very satisfied with their current sexual activity, and 52% reported partnered sexual activity within the last year. Insomnia prevalence was 31%. After multivariable adjustment, higher insomnia scores were associated with lower odds of sexual satisfaction (yes/no) (odds ratio [OR] 0.92, 95% CI, 0.87-0.96). Short sleep duration (<7-8 h) was associated with lower odds of partnered sexual activity (yes/no) (≤5 h, OR 0.88, 95% CI, 0.80-0.96) and less sexual satisfaction (≤5 h, OR 0.88, 95% CI, 0.81-0.95). Shorter sleep durations and higher insomnia scores were associated with decreased sexual function, even after adjustment for potential confounders, suggesting the importance of sufficient, high-quality sleep for sexual function. Longitudinal investigation of sleep and its impact on sexual function postmenopause will clarify this relationship.

    Full Text Available The main purpose of this paper wants to investigate the optimal retailer's lot-sizing policy with two warehouses under partially permissible delay in payments within the economic order quantity (EOQ framework. In this paper, we want to extend that fully permissible delay in payments to the supplier would offer the retailer partially permissible delay in payments. That is, the retailer must make a partial payment to the supplier when the order is received. Then the retailer must pay off the remaining balance at the end of the permissible delay period. In addition, we want to add the assumption that the retailer's storage space is limited. That is, the retailer will rent the warehouse to store these exceeding items when the order quantity is larger than retailer's storage space. Under these conditions, we model the retailer's inventory system as a cost minimization problem to determine the retailer's optimal cycle time and optimal order quantity. Three theorems are developed to efficiently determine the optimal replenishment policy for the retailer. Finally, numerical examples are given to illustrate these theorems and obtained a lot of managerial insights.

    To examine timing of parent-child discussions about sexual topics relative to child-reported sexual behavior. Longitudinal study of employed parents and their children, with an initial survey followed by subsequent surveys 3, 6, and 12 months later. Participants were 141 parents, along with their children (13-17 years), who were control participants in a randomized, controlled trial to evaluate a worksite-based intervention to improve parent-adolescent communication. Main outcomes were parent and child reports of discussion of up to 24 sexual topics and presexual and sexual acts (ranging from handholding to vaginal intercourse) that occurred before the first survey and in the intervals between subsequent pairs of surveys. Sexual topics tend to group into 3 sets. The first set includes topics such as girls' bodies and menstruation and typically coincides with children's presexual stage (handholding, kissing). The second set includes topics such as birth control efficacy and refusing sex and typically coincides with the precoital stage (genital touching and oral sex). The third set typically occurs when children have initiated intercourse. Over half of children engage in genital touching before discussing birth control efficacy, resisting partner pressure for sex, sexually transmitted disease symptoms, condom use, choosing birth control, or partner condom refusal; >40% of children have intercourse before any discussion about sexually transmitted disease symptoms, condom use, choosing birth control, or partner condom refusal. Many parents and adolescents do not talk about important sexual topics before adolescents' sexual debut. Clinicians can facilitate this communication by providing parents with information about sexual behavior of adolescents.

    Teaching sexuality education to support young people's sexual development and overall sexual health is both needed and supported. Data continue to highlight the high rates of teen pregnancy, sexually transmitted disease, including human immunodeficiency virus (HIV) infections, among young people in the United States as well as the overwhelming public support for sexuality education instruction. In support of the implementation of the National Sexuality Education Standards, the current effort focuses on better preparing teachers to deliver sexuality education. An expert panel was convened by the Future of Sex Education Initiative to develop teacher-preparation standards for sexuality education. Their task was to develop standards and indicators that addressed the unique elements intrinsic to sexuality education instruction. Seven standards and associated indicators were developed that address professional disposition, diversity and equity, content knowledge, legal and professional ethics, planning, implementation, and assessment. The National Teacher-Preparation Standards for Sexuality Education represent an unprecedented unified effort to enable prospective health education teachers to become competent in teaching methodology, theory, practice of pedagogy, content, and skills, specific to sexuality education. Higher education will play a key role in ensuring the success of these standards. © 2014, American School Health Association.

  16. Delayed fluorescence in photosynthesis.

    Goltsev, Vasilij; Zaharieva, Ivelina; Chernev, Petko; Strasser, Reto J

    2009-01-01

    Photosynthesis is a very efficient photochemical process. Nevertheless, plants emit some of the absorbed energy as light quanta. This luminescence is emitted, predominantly, by excited chlorophyll a molecules in the light-harvesting antenna, associated with Photosystem II (PS II) reaction centers. The emission that occurs before the utilization of the excitation energy in the primary photochemical reaction is called prompt fluorescence. Light emission can also be observed from repopulated excited chlorophylls as a result of recombination of the charge pairs. In this case, some time-dependent redox reactions occur before the excitation of the chlorophyll. This delays the light emission and provides the name for this phenomenon-delayed fluorescence (DF), or delayed light emission (DLE). The DF intensity is a decreasing polyphasic function of the time after illumination, which reflects the kinetics of electron transport reactions both on the (electron) donor and the (electron) acceptor sides of PS II. Two main experimental approaches are used for DF measurements: (a) recording of the DF decay in the dark after a single turnover flash or after continuous light excitation and (b) recording of the DF intensity during light adaptation of the photosynthesizing samples (induction curves), following a period of darkness. In this paper we review historical data on DF research and recent advances in the understanding of the relation between the delayed fluorescence and specific reactions in PS II. An experimental method for simultaneous recording of the induction transients of prompt and delayed chlorophyll fluorescence and decay curves of DF in the millisecond time domain is discussed.

  17. Do long delay conditioned stimuli develop inhibitory properties?

    Directory of Open Access Journals (Sweden)

    Martha eEscobar

    2015-10-01

    Full Text Available In long-delay conditioning, a long conditioned stimulus (CS is paired in its final segments with an unconditioned stimulus. With sufficient training, this procedure usually results in conditioned responding being delayed until the final segment of the CS, a pattern of responding known as inhibition of delay. However, there have been no systematic investigations of the associative structure of long delay conditioning, and whether the initial segment of a long delay CS actually becomes inhibitory is debatable. In an appetitive preparation with rat subjects, the initial segment of long delay CS A passed a retardation (Experiment 1a but not a summation (Experiment 1b test for conditioned inhibition. Furthermore, retardation was observed only if long delay conditioning and retardation training occurred in the same context (Experiment 2. Thus, the initial segment of a long delay CS appears to share more characteristics with a latent inhibitor than a conditioned inhibitor. Componential theories of conditioning appear best suited to account for these results.

    2010-06-01

    Motivations for and against sex are salient predictors of engaging in or abstaining from sex in cross-sectional studies. Participants (N = 637, 41.4% male) provided data on their motivations for and against sex and lifetime sexual behavior prior to entering college and six months into the first year in college. Longitudinal data were used to examine differences on motivations for and against sex reported the summer before college entrance for students who continued to abstain (Nevers, 44.7%), transitioned to sexual behavior in the following months (Transitioners, 11.0%), and who were previously sexually active (Actives, 44.3%). Multivariate analysis of variance analyses indicated that Transitioners evidenced mean-level differences in motivations surrounding sex (greater intimacy and enhancement motives for sex, lower values motives against sex) prior to their behavioral initiation compared to Nevers. In addition, Transitioners reported greater changes in motivations from pre-college to the six-month follow-up, including increased enhancement motivations for sex and decreased values and not ready motivations against sex. Men reported more important motivations for sex and less important motivations against sex than women, with an interaction showing that sexually experienced women reported more important intimacy motivations and sexually inexperienced men reported more important coping motivations for sex. Identifying salient motivations associated with imminent changes in sexual behavior may support the development of sexual health promotion programs that seek to reach sexually inexperienced individuals at important times of transition.

  20. The Development of the Sexual Assertiveness Questionnaire (SAQ): A Comprehensive Measure of Sexual Assertiveness for Women.

    Science.gov (United States)

    Loshek, Eevett; Terrell, Heather K

    2015-01-01

    Sexual assertiveness has been defined in a number of ways by many researchers, with different aspects of sexual assertiveness emphasized in different measures. Most previous measures have included condom insistence as an important aspect of sexual assertiveness, but this may not translate well to women at all life stages or in varied types of relationships. The goal of the current study was to develop a comprehensive measure of sexual assertiveness that encompasses the aspects of sexual assertiveness that have been emphasized by previous researchers, with the exception of condom insistence. Items were generated based on previous measures and definitions, and an exploratory factor analysis was conducted (Study 1) to better understand the dimensions of sexual assertiveness. The proposed scale was revised and further refined using both exploratory factor analysis and confirmatory factor analysis in Study 2. The final scale consisted of 18 items that seem to capture three dimensions of sexual assertiveness: the ability to initiate and communicate about desired sex, the ability to refuse unwanted sex, and the ability to communicate about sexual history and risk. Model fit indices indicate that this three-factor solution fits the data well. Implications and suggestions for future research are discussed.

    Full Text Available This study evaluated the extent to which a professional training program of an evidence-based intervention for the treatment of child and adolescent victims of sexual abuse could reduce strain and burnout levels in trainees. Participants were 30 psychologists, 19 of whom composed the experimental group (G1 and 11 the comparison group (G2. Data collection occurred before and after the training. The results showed that the ‘work demand’ increased for G1 and remained stable for G2, whereas the ‘control at work’ remained stable for G1 while decreasing for G2. Regarding burnout levels, there was a decrease in depersonalization and stabilization in the levels of emotional exhaustion and reduced professional efficacy for G1, whereas for G2, all the burnout indicators significantly increased. These results partially support the perspective that the training program would have an indirect protective effect on the occupational psychopathology levels of the trainees.

  2. Human sexual response.

    The human sexual response to sexually arousing stimuli is a motivational incentive-based cycle comprising subjective experience and physiologic changes. Clinical and empirical data support a circular model of overlapping phases of variable order. Brain imaging data of sexual arousal identify areas of cerebral activation and inhibition reflecting a complex network of cognitive, motivational, emotional, and autonomic components. Psychologic and biologic factors influence the brain's appraisal and processing of sexual stimuli to allow or disallow subsequent arousal. The sexual and non-sexual outcomes influence motivation to future sexual intimacy. Variability is marked both between individuals and within a person's sexual life, influenced by multiple factors, including stage of life cycle, mental health, and relationship happiness. Neurologic disease can interrupt the cycle at many points: by limiting motivation, reducing ability to attend to and feel sexual stimuli, and accomplishing the movements needed to stimulate and experience intercourse. Impairments to genital congestion, penile erection, and orgasm may also occur. Disease-associated changes to the interpersonal relationship and self-image plus frequently comorbid depression will tend to lessen motivation and temper the brain's appraisal of sexual stimuli, so precluding arousal. Therapy begins by explaining the sexual response cycle, clarifying the points of interruption in the patient's own cycle so as to guide treatment.

    Sexuality is an important component of emotional and physical intimacy that men and women experience throughout their lives. Research suggesting that a high proportion of men and women remain sexually active well into later life refutes the prevailing myth that aging and sexual dysfunction are inexorably linked. Age-related physiological changes do not render a meaningful sexual relationship impossible or even necessarily difficult. Many of these physiological changes are modifiable. There are various therapeutic options available to patients to achieve maximum sexual capacity in old age. This article reviews the prevalence of sexual activity among older adults, the problems these adults encounter with sexual activity, and the role of the health care professional in addressing these problems. The physiological sex-related changes that occur as part of the normal aging process in men and women are reviewed, as well as the effect of age-related physical and psychological illness on sexual function. The attitudes and perceptions of the media and general public toward sexual activity and aging are summarized. An understanding of the sexual changes that accompany the aging process may help general practitioners and other doctors to give practical and useful advice on sexuality as well as refute the misconception that aging equates to celibacy. A thorough awareness of this aspect of older people's quality of life can raise meaningful expectations for aging patients.

  4. Sexual Orientation and Choice

    Full Text Available Is there a choice in sexual orientation? [Wilkerson, William S. (2009: “Is It a Choice? Sexual Orientation as Interpretation”. In: Journal of Social Philosophy 40. No. 1, p. 97–116] argues that sexual desires require interpretation in order to be fully constituted, and therefore sexual orientation is at least partially constituted by choice. [Díaz-León, Esa (2017: “Sexual Orientation as Interpretation? Sexual Desires, Concepts, and Choice”; In: Journal of Social Ontology] critically assesses Wilkerson’s argument, concluding that we still lack a good argument for the claim that choice plays a role in sexual orientation. Here I examine Díaz-León’s response to Wilkerson. I introduce what I call the conceptual act theory of sexual orientation, and argue that even if interpretation were not necessary to constitute sexual desires, it is a necessary element to constitute what we call sexual orientation. However, I conclude that even if we agree that interpretation is involved in sexual orientation, it does not follow that there is a choice involved.

    This study investigated the association between drugs and sexual behavior in a sample of polydrug substance abusers recruited from several Italian therapeutic communities; participants were 90 polydrug substance abusers (opiates, cocaine, amphetamine, inhalants, marijuana/sedatives or hallucinogens abusers) who were compared with 90 nonsubstance-abusing individuals. Sexual behavior was measured by the Italian version of the Sex and the Average Woman (or Man; SAWM), a questionnaire that assesses different kind of sexual attitudes. Results showed that drug-abusing individuals are particularly inclined to search for sexual intercourse and are open to different kinds of sexual experiences; however, they have difficulties in establishing committed and deep relationships with their partners, showing signs of inhibition, affective detachment or anger. Their sexual lives are also surrounded by negative emotions, disturbing thoughts and maladjusted behaviors. The importance of integrating sexual problems into therapeutic strategies is discussed.

  6. Sexual abuse of children and adolescents.

    Parents, relatives, and friends may inflict their passions on children of the same or opposite sex. This is often initiated by sleeping together. Sexual abuse contributes to and causes emotional trauma, although the child's turmoil, confusion, wish for acceptance, and anxiety may be overlooked by the parent and professional. Mutual silence aided by threats adds to the anxiety. Despite the notion that reports of parental sexual exploitation of their children are usually fantasies, there appear to be increasing data that incest and sexual abuse are frequent traumata. At present, there is increased risk of lowering the incest barrier because of increased rates of divorce and step- or surrogate parenthood, since they provide additional potential for being sexually and emotionally traumatized. Sexual abuse seems to be part of a constellation involving neglect and a pathological symbiosis. That sexual abuse is emotionally traumatic is apparent, but it needs emphasizing. Children's defensive reactions may cloud this, and it may be years before such incidents are connected to symptomatic behavior, even when the child is in intensive therapy. In the reported cases, there appears to be a pattern of reactions and defenses related to the traumata that are embedded in imprinting and identification with the aggressor. This leads to sexual abuse being a legacy passed on to the next generation of victims, as the victim becomes the molester through identification. Adolescent self-destructive behavior may stem from guilt about sexually abusing younger children. Therapists may be better able to understand and deal with some of their patients' symptoms if sexual abuse is considered as a possible factor in one or both directions.

    Parents have the potential to protect against adolescent sexual risk, including early sexual behavior, inconsistent condom use, and outcomes such as pregnancy and sexually transmitted infections (STIs). Identification of the specific parenting dimensions associated with sexual risk in adolescence and young adulthood is necessary to inform and focus prevention efforts. The current study examined the relation of proximal (e.g., discussions of sexual costs) and distal (e.g., parental involvement, relationship quality) parenting variables with concurrent and longitudinal adolescent sexual behavior. The National Longitudinal Study of Adolescent Health (Add Health) provided a nationally representative sample with information about the family using adolescent and parent informants. Longitudinal information about sexual risk included adolescent condom use and adolescent sexual initiation, as well as young adult unintended pregnancy, reports of STIs, and biological assay results for three STIs. Higher parent-adolescent relationship quality was associated with lower levels of adolescent unprotected intercourse and intercourse initiation. Better relationship quality was also associated with lower levels of young adult STIs, even when accounting for prior sexual activity. Unexpectedly, more parent reports of communication regarding the risks associated with sexual activity were negatively associated with condom use and greater likelihood of sexual initiation. These results demonstrate that parents play an important role, both positive and negative, in sexual behavior, which extends to young adulthood, and underscores the value of family interventions in sexual risk prevention.

    Ataxia telangiectasia (A-T) is a rare progressive, multisystem genetic disease. Families of children with ultra-rare diseases often experience significant diagnostic delays. We reviewed the diagnostic process for A-T in order to identify causes of delay in an attempt to facilitate earlier identification of A-T in the future. A retrospective case note review of 79 children at the National Paediatric A-T clinic seen since May 2009. Data were collected on the nature and age of initial symptoms, the age at first presentation, measurement of alpha feto-protein (AFP) and age of genetic diagnostic confirmation. At presentation, 71 children (90%) had ataxia. The median presentation delay (from first parental concern to presentation) was 8 months (range 0-118 months), and the median diagnostic delay (genetic confirmation of diagnosis) was 12 months (range 1-109 months). There are significant delays in presentation and diagnostic confirmation of A-T. A greater awareness of A-T and early measurement of AFP may help to improve this.

    We consider time delay for the Dirac equation. A new method to calculate the asymptotics of the expectation values of the operator {intlimits0 ^{∞}e^{iH0t}ζ(\\vert x\\vert /R) e^{-iH0t}dt}, as {R → ∞}, is presented. Here, H 0 is the free Dirac operator and {ζ(t)} is such that {ζ(t) = 1} for {0 ≤ t ≤ 1} and {ζ(t) = 0} for {t > 1}. This approach allows us to obtain the time delay operator {δ {T}(f)} for initial states f in {{H} 2^{3/2+ɛ}({R}3;{C}4)}, {ɛ > 0}, the Sobolev space of order {3/2+ɛ} and weight 2. The relation between the time delay operator {δ{T}(f)} and the Eisenbud-Wigner time delay operator is given. In addition, the relation between the averaged time delay and the spectral shift function is presented.

    This paper deals with the stability for nonlinear teleoperation with time varying communication delays. The proposed method is passivity-based controllers with time varying gains which depend on the rate of change of time varying delay. In our proposed method, stability condition is independent of the magnitude of the communication delay and the damping of the system. The delay-independent stability is shown via Lyapunov stability methods. Several experimental results show the effectiveness o...

  15. Parenting Style and the Timing of Jewish Adolescents’ Sexual Debut

    Full Text Available Parenting style and its effect on the timing of Jewish adolescents’ sexual debuts were examined in the reported study. One hundred sixty-eight research participants between the ages of 18 and 22 from a large university in the Southeast participated in the study. A survey instrument was administered at three fraternities and two sororities to examine parenting style and sexual debut retrospectively. Data were analyzed using descriptive statistics, frequency chi square tests, and Analysis of Variance (ANOVA; while post hoc results were determined through Tukey’s honestly significant difference. Results found that authoritative parenting provides a delay in the age of sexual debut for Jewish adolescents. All other parenting styles had mean ages less than the overall mean age of sexual debut, 17.10 years old, with indifferent parenting having the earliest debut. These findings suggest that parenting style may affect the timing of Jewish adolescents’ sexual debut. The study has implications for understanding factors that may affect the timing of a Jewish adolescent’s sexual debut and may help parents protect their adolescent from the negative effects associated with early sexual debut, such as low academic achievement. Recommendations for future research include exploring the effects of family structure and peer networks to understand fully the many factors that affect the timing of adolescents’ sexual debut.

    This study examined the association between dual-addiction status and sexual compulsivity over time in a sample of self-identified sexually compulsive males. Hierarchical linear modeling was utilized to address the study's research questions. Dually addicted sexually compulsive males exhibited lower rates of sexual compulsivity than their singularly addicted counterparts initially but displayed less precipitous declines in sexual compulsiveness over time. Implications for treatment providers are discussed.

We also compare the results of the different research groups and conclude that although one of the main differences in the results for single degenerate progenitors is the retention efficiency with which accreted hydrogen is added to the white dwarf core, this cannot explain all the differences.

    Equal-arm interferometric detectors of gravitational radiation allow phase measurements many orders of magnitude below the intrinsic phase stability of the laser injecting light into their arms. This is because the noise in the laser light is common to both arms, experiencing exactly the same delay, and thus cancels when it is differenced at the photo detector. In this situation, much lower level secondary noises then set overall performance. If, however, the two arms have different lengths (...

  2. Transgender transitioning and change of self-reported sexual orientation.

    Sexual orientation is usually considered to be determined in early life and stable in the course of adulthood. In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known. We included 115 transsexual persons (70 male-to-female "MtF" and 45 female-to-male "FtM") patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase. The questionnaire focused on sexual orientation and recalled time points of changes in sexual orientation in the context of transition. Participants were further asked to provide a personal concept for a potential change in sexual orientation. In total, 32.9% (n = 23) MtF reported a change in sexual orientation in contrast to 22.2% (n = 10) FtM transsexual persons (p = 0.132). Out of these patients, 39.1% (MtF) and 60% (FtM) reported a change in sexual orientation before having undergone any sex reassignment surgery. FtM that had initially been sexually oriented towards males ( = androphilic), were significantly more likely to report on a change in sexual orientation than gynephilic, analloerotic or bisexual FtM (p = 0.012). Similarly, gynephilic MtF reported a change in sexual orientation more frequently than androphilic, analloerotic or bisexual MtF transsexual persons (p =0.05). In line with earlier reports, we reveal that a change in self-reported sexual orientation is frequent and does not solely occur in the context of particular transition events. Transsexual persons that are attracted by individuals of the opposite biological sex are more likely to change sexual orientation. Qualitative reports suggest that the individual's biography, autogynephilic and autoandrophilic sexual arousal, confusion before and after transitioning, social and self-acceptance, as well as concept of sexual orientation itself may explain this phenomenon.

    2007-03-01

    Low sexual assertiveness has been proposed as a possible mechanism through which sexual revictimization occurs, yet evidence for this has been mixed. In this study, prospective path analysis was used to examine the relationship between sexual refusal assertiveness and sexual victimization over time among a community sample of women. Results provide support for a reciprocal relationship, with historical victimization predicting low sexual assertiveness and low sexual assertiveness predicting subsequent victimization. The effect of recent sexual victimization on subsequent sexual assertiveness also was replicated prospectively. These findings suggest that strengthening sexual assertiveness may help reduce vulnerability to future victimization.

    2010-01-01

    We analyze the time delay between emission of photoelectrons from the outer valence $ns$ and $np$ sub-shells in noble gas atoms following absorption of an attosecond XUV pulse. By solving the time dependent Schr\\"odinger equation and carefully examining the time evolution of the photoelectron wave packet, we establish the apparent "time zero" when the photoelectron leaves the atom. Various processes such as elastic scattering of the photoelectron on the parent ion and many-electron correlation affect the quantum phase of the dipole transition matrix element, the energy dependence of which defines the emission timing. This qualitatively explains the time delay between photoemission from the $2s$ and $2p$ sub-shells of Ne as determined experimentally by attosecond streaking [{\\em Science} {\\bf 328}, 1658 (2010)]. However, with our extensive numerical modeling, we were only able to account for less than a half of the measured time delay of $21\\pm5$~as. We argue that the XUV pulse alone cannot produce such a larg...

This is because the noise in the laser light is common to both arms, experiencing exactly the same delay, and thus cancels when it is differenced at the photo detector. In this situation, much lower level secondary noises then set the overall performance. If, however, the two arms have different lengths (as will necessarily be the case with space-borne interferometers, the laser noise experiences different delays in the two arms and will hence not directly cancel at the detector. In order to solve this problem, a technique involving heterodyne interferometry with unequal arm lengths and independent phase-difference readouts has been proposed. It relies on properly time-shifting and linearly combining independent Doppler measurements, and for this reason it has been called time-delay interferometry (TDI. This article provides an overview of the theory, mathematical foundations, and experimental aspects associated with the implementation of TDI. Although emphasis on the application of TDI to the Laser Interferometer Space Antenna (LISA mission appears throughout this article, TDI can be incorporated into the design of any future space-based mission aiming to search for gravitational waves via interferometric measurements. We have purposely left out all theoretical aspects that data analysts will need to account for when analyzing the TDI data combinations.

    De Luca, Jayme

    2010-01-01

    The equations for the electromagnetic two-body problem are neutral-delay equations that for generic initial data have solutions with discontinuous derivatives. If one wants to use these neutral-delay equations with arbitrary initial data, solutions with discontinuous derivatives must be allowed. Surprisingly, this same neutrality is compatible with the recently developed variational method with mixed-type boundaries for the Wheeler-Feynman electrodynamics. We show that two-body electromagnetic orbits with discontinuous velocities are physically necessary by showing that orbits with vanishing far-fields amost everywhere must have some discontinuous velocities on a few points. We generalize the Wheeler-Feynman electrodynamics with the variational method to include all continuous trajectories, allowing piecewise-differentiable weak solutions represented by trajectories with fields defined almost everywhere (but on a set of points of zero measure where velocities jump). Along with this generalization we formulate...

    Sexual reproduction strategies vary both between and within species in the level of investment in offspring. Life-history theories suggest that the rate of sexual maturation is critically linked to reproductive strategy, with high investment being associated with few offspring and delayed maturation. For humans, age of puberty and age of first sex are two developmental milestones that have been associated with reproductive strategies. Stress during early development can retard or accelerate sexual maturation and reproduction. Early age of menarche is associated with absence of younger siblings, absence of a father figure during early life and increased weight. Father absence during early life is also associated with early marriage, pregnancy and divorce. Choice of partner characteristics is critical to successful implementation of sexual strategies. It has been suggested that sexually dimorphic traits (including those evident in the face) signal high-quality immune function and reproductive status. Masculinity in males has also been associated with low investment in mate and offspring. Thus, women's reproductive strategy should be matched to the probability of male investment, hence to male masculinity. Our review leads us to predict associations between the rate of sexual maturation and adult preferences for facial characteristics (enhanced sexual dimorphism and attractiveness). We find for men, engaging in sex at an early age is related to an increased preference for feminized female faces. Similarly, for women, the earlier the age of first sex the greater the preference for masculinity in opposite-sex faces. When we controlled sexual dimorphism in male faces, the speed of sexual development in women was not associated with differences in preference for male facial attractiveness. These developmental influences on partner choice were not mediated by self-rated attractiveness or parental relationships. We conclude that individuals assort in preferences based on

    2009-08-01

    Full Text Available Sexual abuse is defined as use of child or adolescent by the adults for satisfying of sexual urges and needs with forcing, threatening or tricking. Sexual abuse can be in the form of sexual abuse without touch, sexual touch, interfemoral intercourse, sexual penetration, and sexual exploitation. The prevalence of sexual abuse is reported as 10-40%. It is seen in female four times more than in males. Abusers are frequently male, only 5-15% of them are female. The abuse by females is usually towards male child. Thirty-fifty percent of abuse cases among child and adolescent are outside the family including strangers or familiar person. Some features of abusers are introvert personality, pedophilic and antisocial personality. Most of the abusers have a history of sexual abuse or aggression during childhood. Sexual intercourse between two people who are not allowed to marry by law is called as incest. Family pattern of incest is defined globally as disorganized and dysfunctional. The most commonly reported familial pattern is rigid and patriarchal family pattern with a harsh father using force quite frequently. The clinical features and impacts of the sexual abuse on the child varies according to the relation between abusers and the child, form of abuse, duration of abuse, presence of physical assault, developmental phase, child age and psychological development before the abuse. Sexual abuse history may result in psychiatric disorders including anxiety, depression, substance dependence, suicide act, borderline personality disorder, posttraumatic stress disorder. Abuse negatively affects interpersonal relationships and self esteem of abused individuals. Several studies reported close association between risky sexual behaviors in adulthood and a history of of sexual abuse during childhood. Four traumatic dynamics including traumatic sexuality with abuse, feeling of betrayal, weakness, and stigmatization exist in childhood abuse. Trauma can cause

    This study compared influences from the mass media (television, music, movies, magazines) on adolescents' sexual intentions and behaviors to other socialization contexts, including family, religion, school, and peers. A sample of 1011 Black and White adolescents from 14 middle schools in the Southeastern United States completed linked mail surveys about their media use and in-home Audio-CASI interviews about their sexual intentions and behaviors. Analysis of the sexual content in 264 media vehicles used by respondents was also conducted. Exposure to sexual content across media, and perceived support from the media for teen sexual behavior, were the main media influence measures. Media explained 13% of the variance in intentions to initiate sexual intercourse in the near future, and 8-10% of the variance in light and heavy sexual behaviors, which was comparable to other contexts. Media influences also demonstrated significant associations with intentions and behaviors after all other factors were considered. All contextual factors, including media, explained 54% of the variance in sexual intentions and 21-33% of the variance in sexual behaviors. Adolescents who are exposed to more sexual content in the media, and who perceive greater support from the media for teen sexual behavior, report greater intentions to engage in sexual intercourse and more sexual activity. Mass media are an important context for adolescents' sexual socialization, and media influences should be considered in research and interventions with early adolescents to reduce sexual activity.

    Full Text Available Aim: The assessment of links between traumatic events of sexual nature recollected from the past and patients’ later functioning in sexual life and relationships. Materials and methods: Comorbidity of memories of traumatic sexual events from childhood and adolescence in patients with the features of their current partner relationships was analysed on the basis of Live Inventory completed by 2,582 women and 1,347 men, undergoing treatment between the years 1980-2002, before they were admitted to a day ward of neurotic disorder department. Results: The existence of numerous significant links was observed e.g. the information regarding incest or incest attempt experience was related with a significant risk of a sexual life assessment as completely dissatisfying in women (OR=2.71 and almost completely dissatisfying in men (OR=2.38. Sexual initiation by rape was related with women’s more frequent incidence of getting married as a result of social pressure (OR=3.77 and a feeling of hatred towards a partner (OR=5.41. Men and women who considered themselves completely sexually uneducated (before the age of 18 assessed their sexual life as completely dissatisfying (OR=2.48 and OR=2.07, which was similar to men who would get punished for masturbation or sexual plays by their guardians (OR=2.68. Conclusions: Traumatic events and circumstances relating to sexuality, indicated in the questionnaire interview, turned out to be connected with the risk of dysfunctions in a sexual life and relationship. The traumas included, among others, rape during initiation, early initiation, incest, but also unfavourable circumstances of less traumatic nature such as a lack of sexual education, punishment for masturbation, “mostly undesired initiation”. Their likely effects were rooted in relationship dysfunctions: reasons for their formation, power division, instability, problems with resolving conflicts and, most of all, sexual life dysfunctions. The results were

    Full Text Available Aim. The assessment of links of accumulated traumatic events of a sexual nature, recollected from the past, with the current functioning of the patients in the area of sexual life and relationship. Material and methods. Comorbidity of memories of traumatic sexual events from childhood and puberty in patients with the features of their current partner relationships and sexual life were analyzed on the basis of Live Inventory completed by 2,582 women and 1,347 men, before treatment in day hospital (years 1980-2002. The accumulation was evaluated for a combination of two or three selected events. Results. The presence of relatively numerous traumatic events in the field of sexuality – early initiation or enforced initiation, incest or its attempt, sub-optimal sexual education and punishment for masturbation was indicated. In some patients, these events occurred simultaneously. Especially in women, the presence in the same person of two or three aggravating circumstances of life was associated with a higher risk of among others fleeting, casual sexual contacts, marriage under the influence of environment pressures, reluctance to partner. Conclusions. Increased accumulation – the presence in the same patient of more than one adverse circumstances associated with sexual development – leads to a higher incidence of interference in relationship with a partner including the elements of sexual dysfunction. The obtained results are generally consistent with clinical observations and literature despite different, simplified methodology of the study based on the analysis of single variables from questionnaire interviews. Finding fewer links in the group of men can be explained by their much lower number in the study group and less frequent burdening with certain traumatic events or different experiencing.

    Sexual scripts are widely shared gender and culture-specific guides for sexual behavior with important implications for HIV prevention. Although several qualitative studies document how sexual scripts may influence sexual risk behaviors, quantitative investigations of sexual scripts in the context of sexual risk are rare. This mixed methods study involved the qualitative development and quantitative testing of the Sexual Scripts Scale (SSS). Study 1 included qualitative semi-structured interv...

    Full Text Available Three patients of delayed extradural hematoma (EDH were seen in the last one year among forty eight consecutively treated cases of EDH. All the three hematomas were evacuated. Awareness of this entity and a high degree of vigilance are strongly recommended to detect such cases. Repeat CT should always be done, especially after decompression by either surgical or medical means, recovery from shock or whenever there is evidence of even minimal bleeding under a skull fracture on initial CT scan.

    China is undergoing rapid changes in sexual mores due to several reasons such as decreasing control of the state over private lives of individuals, globalization of its economy, and some policies initiated by the state. There is increased acceptance of premarital sex and extramarital sex in China, especially among youth. In historically conservative China, influenced by Confucian ideals of patriarchal dominance for centuries, the sexual freedom currently enjoyed by many is unprecedented. This has impacted women's status and sexual lives in several positive ways such as increasing freedom of sexual expression, control over their bodies, sexual choices, and increasing equality with men in all spheres of life. However several negative consequences such as a rise in STD/HIV prevalence, commercial sex, and divorce rates have also been attributed to the ongoing sexual revolution in China. Recommendations combating these and suggestions for directions in future research are discussed.
