Donor-linking provisions in New Zealand: counselling roles, concerns and needs.

Donor-linking where those genetically related through donor conception (e.g. donor-conceived persons (DCP), donors and siblings), or recipient parents, search for and connect with each other, is increasingly common, both in identity-release jurisdictions where donors' identifying information may be released to DCP, usually when they become adults - and in anonymous jurisdictions, e.g. as a result of direct-to-consumer DNA testing. In this paper, we explore New Zealand fertility clinic counsellors' views regarding their donor-linking roles and their concerns and needs in relation to current and anticipated service provision. Counsellors believed that fertility service providers had a longer-term responsibility to offer donor-linking services to ensure the wellbeing of all parties affected by donor conception. They perceived their role as complex and multifaceted, encompassing psychoeducation, mediation, advocacy, facilitation, relationship counselling, and therapeutic intervention. They identified significant service provision challenges however, including inadequate staffing, training, time and prioritisation of donor-linking, and inadequate legislative provisions to support practice. Counsellors called for clarity in legislation addressing different contexts of donation and providing measures to ensure the recording of and access to identifying information. They expressed a need for comprehensive, funded donor-linking services, therefore facilitating choice, and services staffed by professionally trained and supported staff.

Extended families? Contact expectations and experiences of egg donors donating to previously unknown recipients.

In New Zealand egg donation is identity-release, and donors may be known to recipients, e.g. family members/friends, or previously unknown e.g. clinic-recruited or sourced through advertising. In the case of unknown donors, New Zealand practice allows donors and recipients to meet face-to-face prior to donation in a joint counselling meeting. While contact details may not necessarily be exchanged in counselling, information-exchange and contact expectations are usually addressed. In previous papers, we explored donors' motivations and experiences of donation. In this paper, we explore donors' ideas around their role in relation to the donor-conceived person (DCP) and their expectations and experiences of information-exchange and contact. While donors did not see themselves as parents and were aware of appropriate boundaries, they described a sense of ongoing connection to DCP, often framing this in extended family terms. They desired to be kept informed about DCP, considered themselves 'on standby' for information requests or in-person contact and valued the opportunity for connection between their children and DCP. Donors were, however, cognisant of the limits to their ability to ensure information-exchange and contact and sometimes struggled with their perceived disempowered position. Meeting prior to donation may both clarify and reinforce expectations of information-exchange and contact.

We want to feel valued: eggs donors' experiences of donation.

Egg donation in New Zealand is identity-release, with donor-conceived individuals having the right to access donors' identifying information at the age of 18. It also allows donors and previously unknown recipients to meet prior to donation. Further, donation is altruistic, although reimbursement of costs is possible. In our previous paper we explored the motivations of 21 egg donors in this context and reported that they are motivated to donate as an act of personal gift-giving to recipients who may become known to them through donation, and that they do not want to be compensated for this financially. In this paper, drawing on in-depth interviews, we report on donors' experiences of the donation process and subsequent to donation. Donors understood their donations to be a significant act, both for the recipients and their families, but also for themselves, particularly given the multiple sacrifices which they willingly made. Donors wished for their gift and their role to be valued and acknowledged through being appreciated, informed, involved and supported by recipients and clinics before, during and after their donations. These findings have implications for clinical practice and care, offering insight into how best to support donors prior and subsequent to donation.

Motivations for egg donation to previously unknown recipients: donation as a personal, relational act of giving.

Egg donation has becoming increasingly common however there is a shortage of donors in many countries, including New Zealand. Research regarding motivations to donate in the context of New Zealand's open-identity and altruistic donation policy and practice is, thus far, limited. This in-depth qualitative study comprised interviews with 21 women to examine their motivations in donating to recipients previously unknown to them. Donors valued parenthood highly and had become aware of the fertility struggles of other women through their own experiences, those of friends or family, or through online personal accounts or advertising. The ability to select recipients and build a comprehensive picture of them, such as through reading recipient profiles or meeting them in person, as is possible in New Zealand, deepened their identification with recipients and thus their empathy and desire to help. They resisted commercial models, positioning themselves as by nature altruistic and regarding their donations as expressions of solidarity and acts of personal gift-giving to specific others who became known to them through donation. Donation was interpreted as a socially relational process, setting up expectations around relationships and ongoing connection. Such understandings have implications for recruitment as well as ongoing experiences and support needs.

Effect of swirling desolvation gas flow in an atmospheric pressure ion source.

A numerical study is performed to examine the effect of introducing a swirling desolvation gas flow on the flow transport characteristics in an electrospray and an atmospheric pressure chemical ionization (APCI) system. An ion source having three coaxial tubes is considered: (1) an inner capillary tube to inject the liquid sample, (2) a center coaxial tube to provide a room temperature gas flow to nebulize the liquid, referred to as the nebulizing gas flow, and (3) an outer coaxial tube having a converging exit to supply a high temperature gas for droplet desolvation, referred to as the desolvation gas flow. The results show that a swirling desolvation gas flow reduces the dispersion of the nebulizing gas and suppresses turbulent diffusion. The effect of swirling desolvation flow on the trajectory of a range of droplet sizes emitted from a source is also considered.

Human papillomavirus vaccination and the primary prevention of cancer: implications for survivors of childhood cancer.

Effective vaccination is now available to prevent human papillomavirus (HPV), the most common sexually transmitted infection and the cause of cervical cancer, the second most common cancer among women worldwide. HPV vaccine uptake is particularly important for females surviving cancer, who are at high risk for HPV-related complication due to the direct and indirect effects of cancer therapy. Thus, Version 3.0 of the Children's Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent and Young Adult Cancer recommends HPV vaccination for all eligible females surviving childhood cancer. Because this vaccine was only FDA approved in 2006, little is known about the complexity of vaccination uptake among those surviving childhood cancer. This chapter describes HPV vaccination and its usefulness in survivors of childhood cancer, provides a rationale for describing survivors as being at increased risk for HPV-related complication, identifies factors that are predictive of HPV vaccination, and discusses the utilization of these predictors in designing strategies to promote adherence to the HPV vaccination recommendations among survivors.

The Influence of Trauma History and Relationship Power on Latinas' Sexual Risk for HIV/STIs.

A community sample of Latinas completed surveys that included measures of sexual abuse and intimate partner violence history, relationship power, negotiating power regarding condom use, perceived HIV/STI risk of sexual partner, and sexual behavior. Over half of the women reported a history of intimate partner violence in the past year and/or sexual abuse in their lifetime. Intimate partner violence was correlated with lower overall sexual relationship power scores, while sexual abuse was correlated with lower condom use negotiating power. More extensive intimate partner violence had the strongest association with higher HIV/STI risk, controlling for relationship status, sexual abuse, and relationship power.

Lifestyle interventions for youth who are overweight: a meta-analytic review.

OBJECTIVE: Clear evidence suggests that lifestyle interventions can be helpful in the treatment of youth who are overweight, but translational research is needed to address the gap between treatment research and clinical care. DESIGN: This meta-analysis integrated the results of 66 treatment-control comparisons and 59 alternate treatment comparisons evaluating lifestyle interventions for children and adolescents who were overweight. MAIN OUTCOME MEASURES: Between-groups differences in weight-related outcomes and other health-related behaviors at the end of treatment. RESULTS: Lifestyle interventions were effective in a range of settings and with a range of participants. Even relatively brief programs had benefits apparent months after the end of treatment. A key component appeared to be the expectation that parents would be actively involved in treatment. Program benefits included not only better weight management but also better eating habits. CONCLUSION: The results suggest that lifestyle interventions can be effective under a wide range of conditions not limited to the highly controlled conditions of efficacy studies. Parent involvement is associated with significantly better results.

Factors influencing familial decision-making regarding human papillomavirus vaccination.

OBJECTIVE: The purpose of this review is to summarize the research regarding Human Papillomavirus (HPV) vaccination uptake among families with adolescent/preadolescent daughters. METHODS: Literature searches (utilizing PubMed and PsychInfo databases) were conducted and research examining psychological and environmental factors which relate to HPV vaccine uptake and intentions was reviewed. RESULTS: Factors such as physician recommendations, perceptions of the beliefs of peers and significant others, history of childhood immunizations, and communication with adolescents regarding sexual topics appear to influence HPV vaccination outcomes. CONCLUSIONS: Although primary prevention of cervical and other cancers is available for preadolescent and adolescent girls, rates of HPV vaccine uptake are low. Future interventions should target vaccine intent and physician/family communication as a means to increasing HPV vaccination.

Human papillomavirus vaccination in survivors of childhood cancer.

Effective vaccination is now available to prevent human papillomavirus (HPV), the most common sexually transmitted infection and the cause of cervical cancer, which is the second most common cancer among women worldwide. HPV vaccine uptake is particularly important for females surviving cancer, some of whom are at high risk for HPV complications because of the direct and indirect effects of cancer treatment. Thus, version 3.0 of the Children's Oncology Group's Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancer recommends HPV vaccination for all eligible females surviving childhood cancer. Because this vaccine was only approved by the US Food and Drug Administration in 2006, little is known regarding the complexity of vaccination uptake among those surviving cancer. The purpose of this article was to describe the HPV vaccine and its usefulness in the survivorship population, provide a rationale for describing cancer survivors as being at increased risk for HPV complications, identify factors associated with HPV vaccination, and discuss the utilization of these predictors in designing strategies to promote adherence to HPV vaccination recommendations within the survivorship context.

Moderators of physical activity and obesity during adolescence.

The purpose of this study was to examine possible moderators of the relation between physical activity and obesity in adolescence. Adolescents (N=168; mean age=15.20 years; 52.4% girls; 76.8% African American) were recruited from low-income primary care medical facilities in a large southern city. Measures included Body Mass Index (BMI) percentile, physical activity, shared family physical activity, and self-efficacy for healthful eating. Multiple regression analyses were conducted to investigate a) independent contributions of physical activity, shared family activity, and self-efficacy for healthful eating to the prediction of adolescent BMI percentile; b) interactions between shared and individual physical activity in the prediction of BMI percentile; c) interactions between self-efficacy for healthful eating and physical activity in the prediction of BMI percentile; and d) interactions among all three variables. Findings revealed self-efficacy for healthful eating was a significant moderator of the adolescent physical activity and BMI percentile relation. Conclusions emphasize the interactive nature among obesity risk factors.

Sperm cryopreservation practices among adolescent cancer patients at risk for infertility.

To assess sperm cryopreservation among males newly diagnosed with cancer aged 13 years and older, attending oncologists assigned infertility risk (yes/no) to patients and reported whether their patients engaged in sperm cryopreservation. Only 28.1% of informed at-risk patients banked sperm. Utilization of sperm banking was significantly associated with a diagnosis of central nervous system (CNS) malignancy or non-CNS solid tumor diagnosis, higher socioeconomic status, and not being a member of an Evangelical religious group. These results suggest that sperm banking is underutilized among adolescent males newly diagnosed with cancer, and that strategies to increase the engagement in this fertility preservation method are needed.

Open-path tunable diode laser absorption spectroscopy for acquisition of fugitive emission flux data.

Air pollutant emission from unconfined sources is an increasingly important environmental issue. The U.S. Environmental Protection Agency (EPA) has developed a ground-based optical remote-sensing method that enables direct measurement of fugitive emission flux from large area sources. Open-path Fourier transform infrared spectroscopy (OP-FTIR) has been the primary technique for acquisition of pollutant concentration data used in this emission measurement method. For a number of environmentally important compounds, such as ammonia and methane, open-path tunable diode laser absorption spectroscopy (OP-TDLAS) is shown to be a viable alternative to Fourier transform spectroscopy for pollutant concentration measurements. Near-IR diode laser spectroscopy systems offer significant operational and cost advantages over Fourier transform instruments enabling more efficient implementation of the measurement strategy. This article reviews the EPA's fugitive emission measurement method and describes its multipath tunable diode laser instrument. Validation testing of the system is discussed. OP-TDLAS versus OP-FTIR correlation testing results for ammonia (R2 = 0.980) and methane (R2 = 0.991) are reported. Two example applications of tunable diode laser-based fugitive emission measurements are presented.

Impact of engine lubricant properties on regulated gaseous emissions of 2000-2001 model-year gasoline vehicles.

The impact of the sulfur (S) content in lubricating oil was evaluated for four ultra-low-emission vehicles and two super-ultra-low-emission vehicles, all with low mileage. The S content in the lube oils ranged from 0.01 to 0.76%, while the S content of the gasoline was fixed at 0.2 ppmw. Vehicles were configured with aged catalysts and tested over the Federal Test Procedure, at idle and at 50-mph cruise conditions. In all testing modes, variations in the S level of the lubricant did not significantly affect the regulated gas-phase tailpipe emissions. In addition to the regulated gas-phase emissions, a key element of the research was measuring the engine-out sulfur dioxide (SO2) in near-real-time. This research used a new methodology based on a differential optical absorption spectrometer (DOAS) to measure SO2 from the lubricants used in this study. With the DOAS, the contribution of SO2 emissions for the highest-S lubricant was found to range from less than 1 to 6 ppm on a gasoline S equivalent basis over the range of vehicles and test cycles used. The development and operation of the DOAS is discussed in this paper.
