Alcohol Use Problems and Sexual Risk Among Young Adult African American Mothers.

Studies have documented high levels of alcohol use and sexual risk among young mothers. We examined parenting satisfaction and self-efficacy in relation to alcohol use problems and sexual risk among 346 young African American women enrolled in an HIV prevention trial, 41 % (n = 141) of whom were mothers. Among mothers, greater parenting satisfaction was associated with a reduced likelihood of problematic alcohol use, having multiple sex partners, and testing positive for Trichomonas vaginalis.

Comparative efficacy of exogenous eCG and progesterone on endogenous progesterone and pregnancy in Holstein cows submitted to timed artificial insemination.

The objectives were to evaluate the effects of the administration of either eCG or progesterone (P4) alone or combined on endogenous P4 concentrations and pregnancy per AI in lactating dairy cows. Cows received a P4-releasing intravaginal device (PRID) and estradiol benzoate on D-8. The PRID was removed and a PGF2α injection was given on D-3.

Effect of Heavy Metals in Plants of the Genus Brassica.

Several species from the Brassica genus are very important agricultural crops in different parts of the world and are also known to be heavy metal accumulators. There have been a large number of studies regarding the tolerance, uptake and defense mechanism in several of these species, notably Brassica juncea and B. napus, against the stress induced by heavy metals.

Social Context and Problem Factors among Youth with Juvenile Justice Involvement Histories.

Youth with juvenile justice histories often reside in poorly resourced communities and report high rates of depression, gang involved networks, and STI-sexual related risk behaviors, compared to their counterparts. The primary aim of this study was to examine the relationship between social context (ie, a combined index score comprised of living in public housing, being a recipient of free school lunch, and witnessing community violence) and risk factors that are disproportionately worse for juvenile justice youth such as depression, gang involved networks and STI sexual risk behaviors. Data were collected from a sample of detained youth ages 14 to 16 (N = 489).

Genetic sensitivity to emotional cues, racial discrimination and depressive symptoms among African-American adolescent females.

Psychosocial stress, including stress resulting from racial discrimination (RD), has been associated with elevated depressive symptoms. However, individuals vary in their reactivity to stress, with some variability resulting from genetic differences. Specifically, genetic variation within the linked promoter region of the serotonin transporter gene (5-HTTLPR) is related to heightened reactivity to emotional environmental cues.

Acceptance of and experiences utilising expedited partner therapy among African-American juvenile girls.

Unlabelled: Background The aim of this study was to describe acceptance of and experiences utilising expedited partner therapy (EPT) among African-American girls recruited from short-term juvenile detention centres.

Methods: Ninety-five detained African-American girls (aged 13-17 years) completed audio computer-assisted self-interviews (ACASI) and self-collected vaginal swab specimens assayed for chlamydia and gonorrhoea. EPT was offered to sexually transmissible infection (STI)-positive participants (n=51); follow-up phone interviews assessed medication delivery to partners.

Virulence and antimicrobial susceptibility of clinical and environmental strains of Aeromonas spp. from northeastern Brazil.

The aims of the present study were to isolate and identify clinical and environmental strains of Aeromonas spp. by means of biochemical tests and the automated method VITEK 2 and to investigate the presence of the virulence genes cytotoxic enterotoxin (act), hemolysin (asa-1), and type III secretion system (ascV), and also the in vitro antimicrobial susceptibility of the strains. From the clinical isolates, 19 Aeromonas hydrophila, 3 Aeromonas veronii bv.

Influence of sexual arousability on partner communication mediators of condom use among African American female adolescents.

Unlabelled: Background Ample evidence shows that partner sexual communication is related to condom use. Although communication about safer sex may often occur when sexual arousal is high, no studies have examined arousability, one's propensity for sexual arousal and partner sexual communication. The purpose of this study was to examine associations between sexual arousability and partner-related mediators of condom use among African American female adolescents, who have disproportionate risk for HIV and sexually transmissible infections (STIs).

Influence of sources of information about influenza vaccine on parental attitudes and adolescent vaccine receipt.

In 2011-2012, only 34% of 13-17 years olds in the United States (US) received seasonal influenza vaccine. Little is known about the link between parents' sources of health information, their vaccine-related attitudes, and vaccination of their adolescent against influenza. This study seeks to determine the relationship between number of sources of information on influenza vaccine, parental attitudes toward influenza vaccine, and influenza vaccine uptake in adolescents.

Comparison of Substance Use Typologies as Predictors of Sexual Risk Outcomes in African American Adolescent Females.

African American female adolescents have a disproportionate risk of sexually transmitted infections (STIs) and other adverse sexual health outcomes. Both alcohol and marijuana use have been shown to predict sexual risk among young African American women. However, no studies have attempted to differentiate alcohol and marijuana typologies use as predictors of sexual risk outcomes exclusively among adolescents who use these substances.

Human papillomavirus vaccination among adolescents in Georgia.

Human papillomavirus (HPV) vaccination coverage for adolescent females and males remains low in the United States. We conducted a 3-arm randomized controlled trial (RCT) conducted in middle and high schools in eastern Georgia from 2011-2013 to determine the effect of 2 educational interventions used to increase adolescent vaccination coverage for the 4 recommended adolescent vaccines: Tdap, MCV4, HPV and influenza. As part of this RCT, this article focuses on: 1) describing initiation and completion of HPV vaccine series among a diverse population of male and female adolescents; 2) assessing parental attitudes toward HPV vaccine; and 3) examining correlates of HPV vaccine series initiation and completion.

Assessment and non-clinical impact of medical devices.

Medical devices (MDs) cover a wide variety of products. They accompany changes in medical practice in step with technology innovations. Innovations in the field of MDs can improve the conditions of use of health technology and/or modify the organisation of care beyond the strict diagnostic or therapeutic benefit for the patients.

Effect of a new device for sustained progesterone release on the progesterone concentration, ovarian follicular diameter, time of ovulation and pregnancy rate of ewes.

This study evaluated the effectiveness of a new progesterone intravaginal device (DPR) in ewes through four experiments: Experiment 1 compared the circulating progesterone concentration of ovariectomized ewes that received either a new or a re-used DPR. Experiment 2 compared the progesterone concentration between DPR-estrous-synchronized ewes and naturally estrous-cycling ewes. Experiment 3 evaluated the effect of new and re-used DPRs on ovarian follicular dynamics and time of ovulation of estrous cycling ewes.

Effects of a high-energy diet on oocyte quality and in vitro embryo production in Bos indicus and Bos taurus cows.

The effects of different dietary energy levels [100 and 170% for maintenance (M) and high energy (1.7M), respectively] on metabolic, endocrine, and reproductive parameters were evaluated in nonlactating Bos indicus (Gir; n=14) and Bos taurus (Holstein; n=14) cows submitted to ultrasound-guided ovum pick-up followed by in vitro embryo production. The oocyte donor cows were housed in a tiestall system and fed twice daily (0800 and 1600 h).

Effect of circulating progesterone concentration during synchronization for fixed-time artificial insemination on ovulation and fertility in Bos indicus (Nelore) beef cows.

Four experiments were designed to evaluate the effect of different circulating progesterone (P4) concentrations during a synchronization of ovulation protocol for the timed artificial insemination (TAI) of Bos indicus (Nelore) beef cattle. In the first trial, 13 ovariectomized Nelore heifers were randomly allocated into one of three groups using new P4 devices (New; 1.0 g P4), previously used P4 devices for 8 days (Used1x), and previously used P4 devices for 16 days (Used2x), in a crossover experimental design.

Associations Between a Dopamine D4 Receptor Gene, Alcohol Use, and Sexual Behaviors among Female Adolescent African Americans.

Adolescent African-American females are disproportionately impacted by HIV, thus there is a clear need to understand factors associated with increased HIV-risk behaviors among this vulnerable population. We sought to explore the association between a dopamine D4 receptor gene (DRD4), a genetic marker associated with natural variations in rewarding behaviors, and self-reported alcohol-use and sexual risk-behaviors, while controlling for other known correlates of risk-taking such as impulsivity, sensation seeking, and peer norms among a group of high-risk African American female adolescents to evaluate whether this biological factor enhances our understanding of patterns of risk in this vulnerable group.

School-Located Vaccination Clinics for Adolescents: Correlates of Acceptance Among Parents.

Four vaccines are recommended by The Advisory Committee for Immunization Practices for adolescents: tetanus, diphtheria, acellular pertussis vaccine (Tdap), meningococcal conjugate vaccine (MCV4), human papillomavirus vaccine (HPV), and annual seasonal influenza vaccine. However, coverage among adolescents is suboptimal. School-located vaccination clinics (SLVCs) offer vaccines to students at school, increasing access.

Impact of Abuse History on Adolescent African-American Women's Current HIV/STD-associated Behaviors and Psychosocial Mediators of HIV/STD Risk.

This study examined if relationship power, sex refusal self-efficacy, and/or fear of condom negotiation mediated the relationship between abuse history and consistent condom use (CCU) among African-American female adolescents (n=593). Participants with an abuse history (58%) were less likely to report CCU (p=.003).

Influence of sexual sensation-seeking on factors associated with risky sexual behaviour among African-American female adolescents.

Unlabelled: Background The identification of antecedents to sexual risk among youth is critical to the development and dissemination of multilevel interventions. Therefore, the aim of the present study was to examine the effect of sexual sensation-seeking on partner age, partner communication, and the sexual attitudes and behaviours of African-American female youth.

Methods: This study examined survey data collected by audio computer-assisted self-interviews from 701 young African-American females between 14 and 20 years of age.

A comparison of two different esters of estradiol for the induction of ovulation in an estradiol plus progestin-based timed artificial insemination protocol for suckled Bos indicus beef cows.

The abilities of two different estradiol esters to induce ovulation in a timed AI (TAI) synchronization protocol in suckled Bos indicus cows were evaluated. In Experiment 1 (synchrony of ovulation), 31 cows were submitted to an estradiol/progestin-based synchronization protocol (Day 0) and randomly assigned to one of three treatments at the time of progestin removal on Day 8: 0.5 or 1.

Combination HIV prevention interventions: the potential of integrated behavioral and biomedical approaches.

Combination HIV prevention interventions that integrate efficacious behavioral and biomedical strategies offer the potential to reduce new HIV infections. We overview the efficacy data for three biomedical HIV prevention approaches, namely microbicides, pre-exposure prophylaxis (PrEP), and HIV vaccination; review factors associated with differential acceptability and uptake of these methods; and suggest strategies to optimize the effectiveness and dissemination of combination HIV prevention approaches. A narrative review was conducted highlighting key efficacy data for microbicides, PrEP, and an HIV vaccination and summarizing acceptability data for each of the three biomedical HIV prevention approaches.

Efficacy of an HIV/STI sexual risk-reduction intervention for African American adolescent girls in juvenile detention centers: a randomized controlled trial.

Few HIV/STI interventions exist for African American adolescent girls in juvenile detention. The objective was to evaluate the efficacy of an intervention to reduce incident STIs, improve HIV-preventive behaviors, and enhance psychosocial outcomes. We conducted a randomized controlled trial among African American adolescent girls (13-17 years, N = 188) in juvenile detention from March 2011 to May 2012.
