Processo de acompanhamento de paciente portadores de feridas na atenção básica

Esta pesquisa tem como objeto de estudo a análise do processo de acompanhamento dos clientes portadores de feridas na atenção primária do município de Angra dos Reis. Os objetivos são: verificar a existência de processo de acompanhamento de clientes portadores de feridas nas unidades de atenção primária do município de Angra dos Reis; analisar as dificuldades inerentes ao processo de acompanhamento de clientes portadores de feridas nas unidades de atenção primária do município de Angra dos Reis. O método foi descritivo, o tipo é de levantamento e de natureza quantitativa. O instrumento de coleta de dados foi o formulário, tendo como sujeitos do estudo a população de enfermeiros atuantes na atenção primária do município de Angra dos Reis e que assinaram o Termo de Consentimento Livre e Esclarecido, conforme disposto na Resolução 196/96 do Conselho Nacional de saúde. O cenário utilizado foi o município de Angra dos Reis. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa do Instituto de Medicina Social da UERJ, através da Plataforma Brasil em 28/06/2013. A análise demonstrou que mais de 93% dos enfermeiros realizam curativos durante sua atuação profissional na atenção primária, destes, 80% realizam algum tipo de acompanhamento de clientes portadores de feridas. Este acompanhamento nem sempre é contínuo, por contada dificuldade técnica do próprio profissional, da interrupção do fornecimento de materiais por parte do almoxarifado, da baixa adesão do cliente e da inexistência de uma rotina institucionalizada. A insuficiência de produtos disponíveis no município para a realização de curativos também foi um fator descrito pelos sujeitos como prejudicador no processo de acompanhamento destes pacientes. Foi verificado que a utilização de produtos de segunda geração para realização de curativos, quando indicados de forma correta e respeitando o prazo de troca, proporciona uma economia nos fastos do município no que se refere ao tratamento tópico de feridas, economia esta que pode chegar à metade dos gastos. Este estudo foi relevante para a otimização do processo de acompanhamento de clientes portadores de feridas no município, bem como reorganização defluxos, rotinas e do cuidado prestado.

Prevalência e fatores relacionados à infecção por HPV em mulheres assistidas pela Estratégia Saúde da Família em Juiz de Fora, Minas Gerais.

O câncer do colo do útero ocasiona 7% dos óbitos por câncer na população feminina brasileira, com taxa de incidência estimada em 15,33/100 mil, sendo a infecção pelo papilomavírus humano (HPV) causa necessária. O rastreamento com citologia do esfregaço cervical convencional é ação escolhida no Brasil e em outros países para prevenir e controlar o câncer, através da detecção precoce das lesões pré-neoplásicas. Porém, apresenta falhas na cobertura, com desigualdade de acesso, e na qualidade, devido aos problemas nas etapas operacionais, desde a coleta na unidade até a interpretação dos resultados. O rastreamento é oportunístico, e uma alternativa organizada pode ser a utilização de cadastros populacionais, como os disponíveis pela Estratégia Saúde da Família (ESF). A efetividade do rastreamento pode ser aumentada com a incorporação de novas técnicas, destacando-se aquelas de biologia molecular, que testam o HPV nas mulheres, em acréscimo ao rastreamento com citologia ou a substituindo integralmente. O conhecimento acerca dos fatores relacionados à infecção vem sendo ampliado para compreender por que mulheres que se encontram em risco semelhante de transmissão apresentam infecção e outras, não. A inexistência de um sistema de vigilância dos tipos circulantes de HPV prejudica a avaliação do cenário atual, inclusive no que se refere à recente implantação da vacinação contra o HPV no calendário básico de vacinação. Neste estudo, o objetivo foi estimar a prevalência de infecção pelo HPV no grupo de mulheres estudadas, relacionando estes achados aos fatores relacionados à infecção, que podem auxiliar na identificação de mulheres mais vulneráveis à infecção e à presença de lesões pré-neoplásicas. 2062 mulheres da periferia de Juiz de Fora, após serem convocadas para rastreamento, participaram do estudo, desenvolvido em duas unidades com a ESF, tendo respondido a um questionário padronizado, submetidas ao exame citológico cervical convencional e testadas para o HPV com o teste cobas 4800 (Roche). A adesão das mulheres convocadas foi semelhante àquela observada em estudos de outros delineamentos, os quais podem contribuir para o seu entendimento. Foram calculadas estimativas de prevalência de infecção pelo HPV segundo características selecionadas. A prevalência global de infecção pelo HPV foi 12,61%. A análise multivariada por regressão de Poisson com variância robusta mostrou associação estatisticamente significativa para ser solteira, consumir bebida alcoólica e ter três ou mais parceiros sexuais ao longo da vida, com razões de prevalência ajustadas de 1,40, 1,44 e 1,35, respectivamente. A prevalência de lesões precursoras do câncer do colo do útero foi 7,27%. A qualidade do esfregaço, avaliada pela representatividade dos epitélios coletados, mostrou que há variação da prevalência de lesões pré-neoplásicas mediante qualidade do esfregaço, porém, não há variação nos resultados do teste HPV mediante a representatividade celular, achado que consistente com uma sensibilidade maior e possivelmente um melhor valor preditivo positivo. A testagem do HPV mostrou ser útil, especialmente entre mulheres com resultado de citologia normal.

Strandings as indicators of marine mammal biodiversity and human interactions off the coast of North Carolina

The adjacency of 2 marine biogeographic regions off Cape Hatteras, North Carolina (NC), and the proximity of the Gulf Stream result in a high biodiversity of species from northern and southern provinces and from coastal and pelagic habitats. We examined spatiotemporal patterns of marine mammal strandings and evidence of human interaction for these strandings along NC shorelines and evaluated whether the spatiotemporal patterns and species diversity of the stranded animals reflected published records of populations in NC waters. During the period of 1997–2008, 1847 stranded animals were documented from 1777 reported events. These animals represented 9 families and 34 species that ranged from tropical delphinids to pagophilic seals. This biodiversity is higher than levels observed in other regions. Most strandings were of coastal bottlenose dolphins (Tursiops truncatus) (56%), harbor porpoises (Phocoena phocoena) (14%), and harbor seals (Phoca vitulina) (4%). Overall, strandings of northern species peaked in spring. Bottlenose dolphin strandings peaked in spring and fall. Almost half of the strandings, including southern delphinids, occurred north of Cape Hatteras, on only 30% of NC’s coastline. Most stranded animals that were positive for human interaction showed evidence of having been entangled in fishing gear, particularly bottlenose dolphins, harbor porpoises, short-finned pilot whales (Globicephala macrorhynchus), harbor seals, and humpback whales (Megaptera novaeangliae). Spatiotemporal patterns of bottlenose dolphin strandings were similar to ocean gillnet fishing effort. Biodiversity of the animals stranded on the beaches reflected biodiversity in the waters off NC, albeit not always proportional to the relative abundance of species (e.g., Kogia species). Changes in the spatiotemporal patterns of strandings can serve as indicators of underlying changes due to anthropogenic or naturally occurring events in the source populations.

Bartonella species detection in captive, stranded and free-ranging cetaceans

We present prevalence of Bartonella spp. for multiple cohorts of wild and captive cetaceans. One hundred and six cetaceans including 86 bottlenose dolphins (71 free-ranging, 14 captive in a facility with a dolphin experiencing debility of unknown origin, 1 stranded), 11 striped dolphins, 4 harbor porpoises, 3 Risso's dolphins, 1 dwarf sperm whale and 1 pygmy sperm whale (all stranded) were sampled. Whole blood (n = 95 live animals) and tissues (n = 15 freshly dead animals) were screened by PCR (n = 106 animals), PCR of enrichment cultures (n = 50 animals), and subcultures (n = 50 animals). Bartonella spp. were detected from 17 cetaceans, including 12 by direct extraction PCR of blood or tissues, 6 by PCR of enrichment cultures, and 4 by subculture isolation. Bartonella spp. were more commonly detected from the captive (6/14, 43%) than from free-ranging (2/71, 2.8%) bottlenose dolphins, and were commonly detected from the stranded animals (9/21, 43%; 3/11 striped dolphins, 3/4 harbor porpoises, 2/3 Risso's dolphins, 1/1 pygmy sperm whale, 0/1 dwarf sperm whale, 0/1 bottlenose dolphin). Sequencing identified a Bartonella spp. most similar to B. henselae San Antonio 2 in eight cases (4 bottlenose dolphins, 2 striped dolphins, 2 harbor porpoises), B. henselae Houston 1 in three cases (2 Risso's dolphins, 1 harbor porpoise), and untyped in six cases (4 bottlenose dolphins, 1 striped dolphin, 1 pygmy sperm whale). Although disease causation has not been established, Bartonella species were detected more commonly from cetaceans that were overtly debilitated or were cohabiting in captivity with a debilitated animal than from free-ranging animals. The detection of Bartonella spp. from cetaceans may be of pathophysiological concern.

刺五加活性成分及其相关非共价复合物的质谱研究

中药化学成分，尤其是活性成分，是中药发挥药效作用的物质基础，它的深入研究是中药现代化的关键和核心。而中药成分的复杂性和药效的整体性，一般的分析及研究方法无法简捷快速地解决中药有效成分鉴定的难题，直接影响到中药研究开发的进程。质谱技术，尤其是软电离质谱及其联用技术，由于其具有灵敏、快速、分辨率高的优点，使得质谱日益成为研究复杂生物分子和中药体系中的应用问题的强有力手段。本论文以刺五加新药的开发为背景，采用有效部分的研究方法，运用先进的质谱技术，以药理活性筛选为指导，全面地研究了刺五加的活性成分。首先，采用电喷雾多极串联质谱技术，研究了正负离子条件下传统中药刺五加中的有效成分刺五加营B和刺五加营E的特征质谱行为，并提出了质谱碎裂机理，可以此鉴定传统刺五加有效成分，对传统刺五加药材及相关药品的快速鉴别和质量控制具有重要意义。以人参皂营R1为例，定量地研究四种碱金属离子浓度对皂普结构分析的影响，为合理添加碱金属离子以提高皂着分析的灵敏度提供了依据。在此基础上，用电喷雾多极串联质谱技术简便而又快捷地区分了两对生理活性差别较大的人参皂营的同分异构体：Rg1和PF11，Rg2和Rg3，为深入研究人参皂普的药效成分和作用机制奠定了一定的基础。系统地研究了β-香树”脂醇型的三种五环三菇皂营在不同模式下的多级串联质谱特征，为从多角度阐明皂昔类化合物的结构提供了新的思路。结构相近的皂普类化合物在电喷雾多级串联质谱中都表现出了与其自身结构相符的特征质谱行为，为不同皂营混合物的快速鉴定提供了一种快速有效的分析方法。在此基础上，研究了两种典型的刺五加仆卜皂营的质谱特征，并用多种质谱手段从刺五加叶总皂普中检测到18种皂普成分，其中有8种皂营成分在刺五加中而未见有文献报道，并用质谱首次发现了刺五加叶皂营的结构和其在植物体内代谢的相关性，这一结果对研究刺五加皂营的体内代谢有着十分重要的意义。以药理目标活性成分为指标，采用对比实验和一系列正交实验，对刺五加活性成分的提取方法，提取工艺和纯化工艺进行了优化，首次采用联合树脂法一次性分离纯化刺五加中两类有效成分总皂昔和总黄酮，经工艺优化最终得到总有效成分达85％以上的刺五加制剂，为刺五加新药的开发提供了大量的工艺参数。基于环糊精包合物（CDs）在中药剂型改造及提高某些药物稳定性和生物利用度方面广阔的应用前景和刺五加新药开发中的实际需要，系统到研究了三种环糊精（a-CD，β-CD和γ-CD）与刺五加皂昔元齐墩果酸（OA）形成的复合物。纬果表明，三种环糊精都能与OA形成稳定的l:1复合物，而β-CD和γ-CD还能与以形成2:1“三明治”状的复合物。复合物气液两相性质具有良好的相关性，为质谱快速筛选和表征这类非共价复合物提供了必要的条件。采用同样的方法对三种环糊精与刺五加中黄酮类化合物（芦丁和懈皮素）的复合物进行了系统研究，结果发观，三种环糊精都与芦丁（R）和棚皮素（Q）形成1:1复合物。但复合物稳定性有差异，对环糊精与芦丁的1:1复合物，以β-CD复合物最稳定，而对于环糊精与槲皮素1:1复合物则以α-CD复合物最稳定，这与芦丁含有糖链有关。刺五加活性成分黄酮类化合物生物利用度和活性的另一有效途径是制备黄酮-金属络合物。黄酮-金属络合物作为潜在的药物开发正日益受到重视，本文利用电喷雾质谱系统地研究了第四周期五种二价金属离子与棚皮素形成的络合物，并采用多级串联质谱部分表征了这些络合物的结构和稳定性之间的关系，为建立黄酮金属络合物筛选体系和表征提供了一种较好的方法，为这类新药的研制开发提供了一定的理论基础。

小麦—偏凸山羊草6Mv/6B代换系的研究

小麦条锈病（Puccinia striiformis f. sp. tritici）是世界性小麦病害，可导致受害小麦减产30%以上，甚至绝收。小麦条锈病在我国西南、华北麦区危害严重，四川麦区是小麦条锈病发病最重的地区之一，每年因条锈病流行造成小麦产量损失巨大。利用抗条锈病品种是控制该病害最安全、经济的有效途径，因此挖掘利用抗病新基因，开展抗病遗传基础研究是当前育种工作中面临的重要任务。 偏凸山羊草（Aegilops ventricosa，DDMvMv，2n=28）是一年生草本植物，起源于地中海西部沿岸地区，具有对小麦白粉病、锈病等高抗或免疫、耐盐、抗寒、蛋白质含量高等优良性状，是小麦遗传育种很好的种质资源。本研究以高抗条锈病的小麦—偏凸山羊草6Mv/6B代换系（Moisson 6Mv/6B）为材料，对其含有的带条锈病抗性基因的偏凸山羊草6Mv染色体在四川小麦背景中的传递情况、与小麦—簇毛麦双端体附加系所具有的白粉病抗性的聚合以及对Moisson 6Mv/6B进行电离辐射诱变筛选抗条锈病的小麦—偏凸山羊草易位系三个方面进行了研究。取得的主要研究结果如下： 1. Moisson 6Mv/6B与高感条锈病的四川地区普通小麦品种绵阳26、绵阳93-124和SW3243的杂种F1与其普通小麦亲本分别作为父、母本回交，通过对其BC1和F2的结实率、根尖细胞有丝分裂中期染色体的观察以及对条锈病抗性的鉴定，发现含6Mv染色体的F1植株作母本时的回交结实率（83.10%）普遍高于含6Mv染色体的F1植株作父本（48.61%），结实率与普通小麦基因型密切相关（χ2=34.15>>χ20.05=5.99（df=2））；6Mv染色体在三种四川小麦中通过雌、雄配子传递的传递方式与其传递率间没有显著相关性，其传递率与普通小麦基因型呈显著相关性（χ2=6.42>χ20.05=5.99（df=2））。 2. Moisson 6Mv/6B与高抗白粉病的小麦—簇毛麦双端体附加系Pana（2n=42+2t）正反杂交，希望在聚合两者抗性的同时观察不同受体背景下的抗性反应。对Moisson 6Mv/6B和Pana正反杂交的结实率、杂交后代的农艺性状进行观察，并对杂交后代进行基因组荧光原位杂交（GISH）分析及条锈病和白粉病的抗性鉴定。结果表明Moisson 6Mv/6B作母本时杂交结实率（80.56%）高于Pana作母本时（58.33%），结实率与杂交方式间紧密相关（χ2=4.96>χ20.05=3.84（df=1））；Moisson 6Mv/6B和Pana杂交后代株高比最高亲本高约10cm，成熟期也较两亲本提前两个星期左右；正反杂交后代中具有偏凸山羊草6Mv染色体的植株具有条锈病抗性，具有簇毛麦端体的植株具有白粉病抗性，同时筛选到4株含有偏凸山羊草和簇毛麦遗传物质并对条锈病和白粉病兼抗的材料，证明来自偏凸山羊草6Mv染色体的条锈病抗性与来自簇毛麦端体的白粉病抗性已经聚合在一起，且没有产生相互抑制的作用，暗示通过这两个抗性基因的聚合是完全能获得兼抗条锈病和白粉病的小麦新种质。 3. 对Moisson 6Mv/6B在减数分裂时期的成株进行总剂量为6Gy、辐射频率为120rad/min的60Co-γ射线辐射，对辐射植株自交后代进行农艺性状及根尖细胞有丝分裂中期染色体形态观察和条锈病抗性鉴定。结果为辐射植株自交结实率为2.22%，根尖细胞有丝分裂中期的染色体存在明显碎片，辐射自交后代植株对条锈病具有成株期抗性。 小麦—偏凸山羊草6Mv/6B代换系对条锈病抗性稳定，是培育条锈病抗性品种的良好供体。本研究证明在四川小麦背景中要利用该品种抗性，在结实数满足需要时，可将其作父本，亦可作母本，但关键是要选择好一个优良的受体基因型；同时其条锈病抗性与来自簇毛麦的白粉病抗性没有相互抑制作用，可将两者抗性有效聚合用于小麦育种中。 Wheat stripe rust (Puccinia striiformis f. sp. Tritici) is a worldwide disease of wheat, and could lead to victims of 30 percent or even total destruction of wheat production. Wheat stripe rust harms badly in China's southwest and North China. Sichuan province is one of the regions damaged by wheat stripe rust heavily. The use of resistant varieties is the most secure and economical way to control the wheat stripe rust. Therefore, it is essential to identify new disease-resistant genes and genetically research of disease resistance. Aegilops ventricosa (DDMvMv, 2n = 28) is an annual herbaceous plant, originating in the coastal areas of the western Mediterranean, with good characters such as resistance of wheat powdery, rust, salt, cold and high protein content. It is a good germplasm resource. In this study, the wheat- Aegilops ventricosa 6Mv/6B substitution line Moisson 6Mv/6B (highly resistant to the wheat stripe rust) was used to study on the transmission of chromosome 6Mv of Aegilops ventricosa in different genetic background of Sichuan wheat varieties, hybridization with wheat- Haynaldia villosa ditelosomic addition line Pana (highly resistant to the powdery mildew) and screening of wheat- Aegilops ventricosa translocation line by exposuring Moisson 6Mv/6B under ionizing radiation. The main results are as following: 1. Moisson 6Mv/6B was crossed with Sichuan wheat varieties mianyang26, mianyang93-124 and SW3243 (highly susceptible to stripe rust), respectively. Their F1 hybrids were further backcrossed as male and female to corresponding wheat varieties. The seed-setting rate, chromosomes confirmation in the mitotic metaphase of root tip cells, and resistance to stripe rust of the subsequent BC1 and F2 plants were investigated. The average seed-setting rate of backcross via 6Mv as female donor (83.10%) was higher than that of backcross via 6Mv as male donor (48.61%), suggesting that the seed-setting rate was associated with the wheat genotypes（χ2=34.15>>χ20.05=5.99（df=2））. In all analyzed populations, transmission frequencies of chromosome 6Mv were not correlated with the ways of 6Mv through male or through female. However, transmission frequencies of chromosome 6Mv were significantly correlated with Sichuan wheat genotypes（χ2=6.42>χ20.05=5.99（df=2））. 2. To aggregating the resistances to stripe rust and powdery mildew, as well as research on the resistance reactions in different genetic background, Moisson 6Mv/6B was reciprocally hybrided with the wheat- Haynaldia villosa ditelosomic addition line Pana (highly resistant to the powdery mildew). The seed-setting rate, agronomic characters, genomic in situ hybridization (GISH) of hybrid progenies，and resistances to stripe rust and powdery mildew were investigated. The results showed that the seed-setting rate of hybridization via Moisson 6Mv/6B as female donor (80.56%) was significant higher than that via Pana as female donor (58.33%). The seed-setting rate was associated with the hybrid methods (χ2 = 4.96> χ20.05 = 3.84 (df = 1)). The plant height of hybrid progenies was about 10 cm higher than Pana, the parent with maximum height. And the maturity of hybrid progenies was about two weeks earlier than that of the parents. In the hybrid progenies, the plants with the 6Mv chromosome have the resistance to stripe rust and the plants with the telosome from Haynaldia villosa have the resistance to powdery mildew. It was found that four plants with both the 6Mv chromosome and the telosome from Haynaldia villosa were resistant to stripe rust and powdery mildew. It indicated that the resistance to stripe rust and powdery mildew aggregated, and no mutual inhibition was found. It implied that the aggregation of the two resistance genes was able to provide the new wheat germplasm with the resistances to stripe rust and powdery mildew. 3. Moisson 6Mv/6B was irradiated with 60Co-γ rays of 6Gy (120rad/min) during meiosis. The agronomic characters and chromosomes confirmation in the mitotic metaphase of root tip cells，as well as resistance to stripe rust were investigated. The seed-setting rate of irradiated plants was only 2.22%. The chromosomes in mitotic metaphase had clear fragments. The resistance to stripe rust of progeny of irradiated plants was the adult-plant resistance. The wheat- Aegilops ventricosa 6Mv/6B substitution line is a good stripe rust resistance donor for its stabile resistance. Our study demonstrated that the key for use the resistance is to choose a good receptor. There is no difference between Moisson 6Mv/6B be the female and be the male if the seed number meets the requirement. At the same time, the stripe rust resistance of Moisson 6Mv/6B did not have the mutual inhibition with the powdery mildew resistance from Haynaldia villosa. It is able to aggregate the two resistances for wheat breeding.

Prevalence of overweight and obesity among nurses in Scotland: A cross-sectional study using the Scottish Health Survey.

Background Increasing prevalence of overweight and obesity represents a global pandemic. As the largest occupational group in international healthcare systems nurses are at the forefront of health promotion to address this pandemic. However, nurses own health behaviours are known to influence the extent to which they engage in health promotion and the public's confidence in advice offered. Estimating the prevalence of overweight and obesity among nurses is therefore important. However, to date, prevalence estimates have been based on non-representative samples and internationally no studies have compared prevalence of overweight and obesity among nurses to other healthcare professionals using representative data. Objectives To estimate overweight and obesity prevalence among nurses in Scotland, and compare to other healthcare professionals and those working in non-heath related occupations. Design Cross-sectional study using a nationally representative sample of five aggregated annual rounds (2008-2012) of the Scottish Health Survey. Setting Scotland. Participants: 13,483 adults aged 17 to 65 indicating they had worked in the past 4 weeks, classified in four occupational groups: nurses (n = 411), other healthcare professionals (n = 320), unqualified care staff (n = 685), and individuals employed in non-health related occupations (n = 12,067). Main outcome measures: Prevalence of overweight and obesity defined as Body Mass Index ≥ 25.0. Methods Estimates of overweight and obesity prevalence in each occupational group were calculated with 95% confidence intervals (CI). A logistic regression model was then built to compare the odds of being overweight or obese with not being overweight or obese for nurses in comparison to the other occupational categories. Data were analysed using SAS 9.1.3. Results 69.1% (95% CI 64.6,73.6) of Scottish nurses were overweight or obese. Prevalence of overweight and obesity was higher in nurses than other healthcare professionals (51.3%, CI 45.8,56.7), unqualified care staff (68.5%, CI 65.0,72.0) and those in non-health related occupations (68.9%, CI 68.1,69.7). A logistic regression model adjusted for socio-demographic composition indicated that, compared to nurses, the odds of being overweight or obese was statistically significantly lower for other healthcare professionals (Odds Ratio [OR] 0.45, CI 0.33,0.61) and those in non-health related occupations (OR 0.78, CI 0.62,0.97). Conclusions Prevalence of overweight and obesity among Scottish nurses is worryingly high, and significantly higher than those in other healthcare professionals and non-health related occupations. High prevalence of overweight and obesity potentially harms nurses’ own health and hampers the effectiveness of nurses’ health promotion role. Interventions are therefore urgently required to address overweight and obesity among the Scottish nursing workforce.

Researcher practices on returning genetic research results.

BACKGROUND/AIMS: as genetic and genomic research proliferates, debate has ensued about returning results to participants. In addition to consideration of the benefits and harms to participants, researchers must also consider the logistical and financial feasibility of returning research results. However, little data exist of actual researcher practices. METHODS: we conducted an online survey of 446 corresponding authors of genetic/genomic studies conducted in the United States and published in 2006-2007 to assess the frequency with which they considered, offered to, or actually returned research results, what factors influenced these decisions, and the method of communicating results. RESULTS: the response rate was 24% (105/446). Fifty-four percent of respondents considered the issue of returning research results to participants, 28% offered to return individual research results, and 24% actually returned individual research results. Of those who considered the issue of returning research results during the study planning phase, the most common factors considered were whether research results were deemed clinically useful (18%) and respect for participants (13%). Researchers who had a medical degree and conducted studies on children were significantly more likely to offer to return or actually return individual results compared to those with a Ph.D. only. CONCLUSIONS: we speculate that issues associated with clinical validity and respect for participants dominated concerns of time and expense given the prominent and continuing ethical debates surrounding genetics and genomics research. The substantial number of researchers who did not consider returning research results suggests that researchers and institutional review boards need to devote more attention to a topic about which research participants are interested.
