prioritization

优先顺序
  • 文章类型: Journal Article
    在加拿大,五分之一的人患有慢性疼痛,一种经常与其他慢性疾病同时发生的疾病。和大多数慢性病一样,成功参与症状管理是关键.在多种疾病的背景下,自我管理涉及症状和状况的日常优先排序和决策,这可能是具有挑战性的。慢性病的自我管理可能需要更复杂的能力和任务来解决每种疾病的不同影响。
    我们的研究目标是探索患有慢性疼痛和其他慢性疾病的成年人自我管理症状优先排序的类型和过程。
    这项研究是作为一项较大研究的一部分进行的,该研究采用了解释性的顺序混合方法设计。这项研究更具体地集中在研究的定性部分。
    为定性部分招募的参与者在蒙特利尔大学中心医院在线或面对面地参加了半结构化的个人访谈。
    总共,25名参与者接受了采访,包括18名女性和7名男性。
    要参与研究的定性部分,参与者从较大的研究中选出,如果他们年龄在18岁或以上,并且疼痛时间超过3个月,并且至少有一种其他慢性疾病正在接受治疗或参与症状管理,则他们符合研究条件.半结构化访谈是亲自或虚拟进行的,并逐字记录。反思主题分析用于探索患者的叙述,并采用了开放和迭代的方法来编码访谈和生成主题。
    第一个主题,专注于症状优先排序,显示了不同的优先级过程,包括优先考虑显性疾病,优先考虑多种疾病,以避免不良后果,最后是缺少或自动进行优先级排序的过程。在第二个主题中,我们确定了疾病的几个特征,在这种情况下,慢性疼痛使其成为自我管理的优先事项:无法控制和致残的性质,无所不在,不可预测性,不愉快,和对他人的隐形。在最后一个主题中,我们强调,一些社会心理因素影响了自我管理和优先过程的参与程度,包括社会支持和医患关系。
    慢性疼痛是参与者在自我管理任务中最常优先考虑的医疗状况。由于其特点,对日常功能产生负面影响的是医疗条件。
    UNASSIGNED: In Canada, one out of five people lives with chronic pain, a condition frequently co-occurring with other chronic illnesses. As with most chronic illnesses, successful engagement in symptom management is key. In the context of multiple illnesses, self-management involves daily prioritization of symptoms and conditions and decision-making, which can be challenging. Self-management of chronic illnesses can require more complex competence and tasks to address the different implications of each condition.
    UNASSIGNED: Our research objective was to explore types and processes of self-management symptom prioritization among adults living with chronic pain and other chronic illnesses.
    UNASSIGNED: This research was carried out as part of a larger study that adopted an explanatory sequential mixed-methods design. This study focused more specifically on the qualitative part of the study.
    UNASSIGNED: Participants recruited for the qualitative component took part in a semi-structured individual interview online or in-person at the center hospitalier de l\'Université de Montréal.
    UNASSIGNED: In total, 25 participants were interviewed, including 18 women and 7 men.
    UNASSIGNED: To participate in the qualitative part of the study, participants were selected from the larger study and were eligible if they were 18 years old or older and experiencing pain for more than 3 months and had at least one other chronic illness for which they were receiving treatment or engaged in symptom management. Semi-structured interviews were conducted in-person or virtually and were transcribed verbatim. Reflexive thematic analysis was used to explore patients\' narratives, and an open and iterative approach was adopted to code interviews and generate themes.
    UNASSIGNED: The first theme, focus on symptom prioritization, showed different prioritization processes, including prioritizing a dominant illness, prioritizing multiple illnesses to avoid undesirable consequences, and finally absence of or automatic processes of prioritization. In the second theme, we identified several characteristics of an illness, in this case chronic pain that made it a self-management priority: uncontrollable and disabling nature, omnipresence, unpredictability, unpleasantness, and invisibility to others. In the last theme, we highlighted that some psychosocial factors influenced levels of engagement in self-management and prioritization processes, including social support and the patient-physician relationship.
    UNASSIGNED: Chronic pain was the medical condition most often prioritized by participants in their self-management tasks. Because of its characteristics, it was the medical condition that had the most negative impact on day-to-day functioning.

    背景:当护士遇到复杂的情况需要道德上具有挑战性的护理判断时,就会出现优先决策。这种现象很少在养老院进行研究。优先决策可能导致社会和医疗保健领域的个人可能无法获得所需的所有服务。做出优先决定和对其后果的认识可以增加护士的工作量。
    目的:描述养老院未完成护理的优先决策。
    方法:通过个别主题访谈进行的定性描述性研究。参与者是通过社交媒体招募的。使用归纳内容分析对数据进行分析。
    方法:在芬兰老年人疗养院工作的护士(n=23)。数据收集于2022年6月至2023年2月之间。
    方法:芬兰立法不强制要求伦理审查或研究许可,参与者以私人身份参加。[请作者在此提及知情同意程序和匿名]。
    结果:护士指出,优先决策的需要来自与护士参与以人为本的护理相关的挑战,工作社区的文化,与领导相关的工作量和挑战带来的负担。优先决策以居民利益为基础,追求高效的工作流程和护士的个人利益。护士没有得到有关未完成护理的决策的支持,在其工作社区中尚未制定优先次序的协议。优先决策和未完成的护理被隐藏起来,没有说出来。
    结论:护理领导者应该解决这种隐藏的现象,通过与护士的讨论以及让他们参与协议的制定,使其可见。这些发现可用于开发新的方法来支持护士并减少他们的工作量,并提高养老院护理的质量和以人为本。
    BACKGROUND: Prioritization decision-making arises when nurses encounter intricate situations that demand ethically challenging judgments about care. This phenomenon has rarely been studied in nursing homes. Prioritization decision-making may lead to instances where individuals in social and healthcare may not receive all services they need. Making prioritization decisions and awareness of their consequences can increase nurses\' workload.
    OBJECTIVE: To describe prioritization decision-making regarding unfinished nursing care in nursing homes.
    METHODS: A qualitative descriptive study conducted through individual theme interviews. Participants were recruited through social media. The data was analyzed using inductive content analysis.
    METHODS: Nurses (n = 23) working in nursing homes for the elderly people in Finland. Data were collected between June 2022 and February 2023.
    METHODS: Finnish legislation does not mandate an ethical review or research permits, as the participants took part as private individuals. [ask authors to make reference here to informed consent process and anonymity].
    RESULTS: Nurses stated that the need for prioritization decision-making arises from challenges associated with nurses\' engagement with person-centered care, the culture of the work community, the burden due to workload and challenges associated with the leadership. Prioritization decision-making was based on the interests of residents, striving for an efficient workflow and nurse\'s personal interests. Nurses did not receive support for decision-making regarding unfinished care, and protocols for prioritization had not been established in their work communities. Prioritization decision-making and unfinished care were concealed and left unspoken.
    CONCLUSIONS: Nursing leaders should address this hidden phenomenon, making it visible through discussions with nurses and by involving them in the development of protocols. The findings can be utilized for developing new approaches to support nurses and reduce their workload and for enhancing the quality and person-centeredness of nursing care in nursing homes.

    生物多样性保护需要最新的高质量数据和有效的方法来优先考虑保护物种和地点。在这里,我们优先考虑了Aggtelek国家公园的直翅目栖息地,基于居住在98个地点的69个直翅目物种的修订和实际分布数据。简单排序和互补区域方法与物种丰富度(S)一起使用,稀有性加权物种丰富度(SR),和稀有物种数量(SQ)。此外,还测试了将欧洲和当地稀有性和该物种的扩散能力结合在一起的蝗虫保护指数(GCI“和GCIn”)。与简单的排名相反,互补区域方法代表了整个动物区系和物种现场数据记录的重要部分。所有使用的指标表现相似,除了标准化的GCIn“,它受到研究强度差异的影响。Aggtelek国家公园的高度优先区域被指定在Jósvafà和Aggtelek村庄上方的高原上以及小村庄中,在约斯瓦夫附近的孤立的小山(Sz_l_hegy)上覆盖着以前葡萄园的马赛克,果园和干草地.有效指数的组合使用提供了额外的排名,可以最好地选择热点,以支持在自然保护中有效使用有限的资源。
    The biodiversity conservation needs recent high-quality data and efficient methods for prioritizing species and sites for conservation. Here we prioritized Orthoptera habitats of the Aggtelek National Park, based on revised and actualized distribution data of 69 Orthoptera species living at 98 sites. The simple ranking and complementary areas methods were used with species richness (S), rarity weighted species richness (SR), and number of rare species (SQ). Additionally, the Grasshopper Conservation Indexes (GCI\" and GCIn\") combining European and local rarity and dispersal capacity of the species were also tested. Contrary to simple ranking the complementary areas method represented the whole fauna and significant part of the species-site data records. All the used indices performed similar except the standardized GCIn\" which is highly affected by the differences in study intensity of sites. High-priority areas of the Aggtelek National Park were designated in the plateau above Jósvafő and Aggtelek villages and in the small, isolated hill near Jósvafő (Szőlő-hegy) covered with remained mosaic of former vineyards, orchards and hayfields. The combined use of the efficient indices provides additional ranking that allows the best selection of hotspots to support efficient use of limited resources in nature conservation.

    紫外线(UV)过滤剂是在人体组织中高浓度发现的新兴污染物。食物摄入通常被认为是人类暴露于污染物的主要途径。在这项研究中,184个复合食品样品,从中国23个省收集的八个类别的4268个个体样本中制备,用于第六次中国总饮食研究,进行了分析。食品样品中的总紫外线过滤剂浓度和中值为1.5-68.3和7.9ng/g湿重,分别。最高的中位数浓度是在肉类中按递减顺序发现的,谷物,和豆类。总的来说,分析了15种UV过滤剂。水杨酸2-乙基己酯,同盐酸盐,和2-乙基己基-4-甲氧基肉桂酸酯占主导地位,中位数贡献为34.1%,22.6%,和14.5%,分别,和2-(2H-苯并三唑-2-基)-4,6-二叔戊基苯酚贡献的中值为0.03%,总紫外线过滤剂浓度。来自同一省份的动物源性食品中估计的每日紫外线过滤剂总摄入量与人乳中的紫外线过滤剂总浓度显着相关(r=0.44,p<0.05)。预测吸收,分布,新陈代谢,和消除特性导致10种紫外线过滤剂被优先考虑为最可能保留在人体组织中。优先排序结果和毒性评估表明,辛炔和2-乙基己基-4-甲氧基肉桂酸酯在体内具有更强的作用,因此需要比其他药物更多的关注。
    Ultraviolet (UV) filters are emerging contaminants that have been found in high concentrations in human tissues. Food intake is generally considered to be the primary route of human exposure to contaminants. In this study, 184 composite food samples, prepared from 4268 individual samples in eight categories collected from 23 Chinese provinces for the sixth Chinese total diet study, were analyzed. The total and median UV filter concentrations in food samples were 1.5-68.3 and 7.9 ng/g wet weight, respectively. The highest median concentrations were found in decreasing order in meat, cereals, and legumes. In total, 15 UV filters were analyzed. 2-Ethylhexyl salicylate, homosalate, and 2-ethylhexyl-4-methoxycinnamate were dominant and made median contributions of 34.1%, 22.6%, and 14.5%, respectively, and 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol contributed the median of 0.03%, of the total UV filter concentrations. The estimated total daily UV filter intake in animal-origin foods and total UV filter concentration in human milk from the same province were significantly correlated (r = 0.44, p < 0.05). Predicted absorption, distribution, metabolism, and elimination properties led to 10 UV filters being prioritized as most likely to be retained in human tissues. The prioritization results and toxicity assessments indicated that octocrylene and 2-ethylhexyl-4-methoxycinnamate have stronger effects in vivo and therefore require more attention than others.

    背景:关于如何优先考虑HIV暴露前预防(PrEP)交付的潜在实施策略,缺乏共识。在资源有限的情况下,我们比较了几种优先排序方法的一致性和实用主义。
    方法:我们在肯尼亚的55家机构中与具有临床PrEP交付和PrEP决策经验的不同利益相关者合作,优先考虑16种PrEP交付策略。我们比较了四种策略优先级方法:(1)“过去的经验调查”与经验丰富的从业人员反思实施经验(N=182);(2和3)小组讨论前后的“小组前和小组后排名”调查(N=44和40);(4)感知有效性与可行性的“去区”象限图。使用Kendall的相关性分析来比较使用这四种方法的策略优先级。此外,参与者被要求通过电话和在线调查将策略分组为三个捆绑包,最多四个策略/捆绑包.
    结果:在前和后小组排名之间,策略排名相关性最强(Tau:0.648;p<0.001)。去区地块与小组后排名之间存在中等相关性(Tau:0.363;p=0.079),过去的经验调查与小组后排名之间存在中等相关性(Tau:0.385;p=0.062)。对于策略捆绑,参与者主要按照列出的顺序选择捆绑的策略,反映期权排序偏差。电话和在线方法都不能有效地选择策略包。与会者一致认为,研讨会期间开展的战略排名活动有助于确定最后一套战略的优先次序。
    结论:有经验和没有经验的利益相关者参与者的战略排名倾向于优先考虑被认为是可行的战略。小组讨论的重点是可行性和有效性,这表明优先事项与个人排名略有不同。战略捆绑方法,虽然时间和资源消耗较少,没有效果。未来的研究应进一步比较方法的相对有效性和实用主义,以优先考虑实施策略。
    BACKGROUND: There is a lack of consensus about how to prioritize potential implementation strategies for HIV pre-exposure prophylaxis (PrEP) delivery. We compared several prioritization methods for their agreement and pragmatism in practice in a resource-limited setting.
    METHODS: We engaged diverse stakeholders with clinical PrEP delivery and PrEP decision-making experience across 55 facilities in Kenya to prioritize 16 PrEP delivery strategies. We compared four strategy prioritization methods: (1) \"past experience surveys\" with experienced practitioners reflecting on implementation experience (N = 182); (2 and 3) \"pre- and post-small-group ranking\" surveys before and after group discussion (N = 44 and 40); (4) \"go-zone\" quadrant plots of perceived effectiveness vs feasibility. Kendall\'s correlation analysis was used to compare strategy prioritization using the four methods. Additionally, participants were requested to group strategies into three bundles with up to four strategies/bundle by phone and online survey.
    RESULTS: The strategy ranking correlation was strongest between the pre- and post-small-group rankings (Tau: 0.648; p < 0.001). There was moderate correlation between go-zone plots and post-small-group rankings (Tau: 0.363; p = 0.079) and between past-experience surveys and post-small-group rankings (Tau: 0.385; p = 0.062). For strategy bundling, participants primarily chose bundles of strategies in the order in which they were listed, reflecting option ordering bias. Neither the phone nor online approach was effective in selecting strategy bundles. Participants agreed that the strategy ranking activities conducted during the workshop were useful in prioritizing a final set of strategies.
    CONCLUSIONS: Both experienced and inexperienced stakeholder participants\' strategy rankings tended to prioritize strategies perceived as feasible. Small group discussions focused on feasibility and effectiveness revealed moderately different priorities than individual rankings. The strategy bundling approach, though less time- and resource-intensive, was not effective. Future research should further compare the relative effectiveness and pragmatism of methodologies to prioritize implementation strategies.

    在第一波COVID-19大流行期间,来自不同欧盟国家的令人不安的报告表明,在需要进行三级分诊的情况下,需要支持决策工具和建议。COVID-19患者主要依次出现,不是平行的,因此,预计事后分流方案比事前分流方案更有可能。在这些情况下,决策者可能极易受到第二受害者和道德伤害的影响,因此,在压倒性的关键案例中,需要可靠和道德上合理的算法。要收集有关潜在三级分诊仪的基本信息,我们使用Delphi技术设计了由专家组开发的三维仪器。该仪器集中在三个参数上:1)估计的生存机会,2)治疗后恢复自主性的估计预后,和3)估计在ICU的住院时间。要验证和测试仪器,我们在5家德国医院进行了一项匿名在线调查,调查对象是在发生大规模感染事件时负责决策的医生.在大约80名医生中,47回答向他们展示了16个虚构的ICU病例小插曲(包括3个双曲),他们必须使用仪器的三个参数进行评分。我们检测到良好的结构效度(Cronbach'sAlpha0.735)和内部可靠性(p<0.001,CohensKappa0.497至0.574),但三个参数的间可靠性较低(p<0.001,科恩的Kappa为0.252至0.327)。对于估计的ICU住院时间,检测到最佳的相互可靠性。进一步的分析揭示了在评估潜在剩余自主权的预后方面的担忧,尤其是只有身体损伤的患者。根据德国的建议,我们得出的结论是,应避免单一评级患者分诊(这可能发生在压力大和资源高度有限的情况下),以确保患者和卫生保健提供者的安全.未来的工作应该集中在可靠和有效的群体决策工具和算法,并质疑生存的机会作为一个单一的分类参数是否应该补充其他参数,例如在ICU的估计停留时间。
    Disconcerting reports from different EU countries during the first wave of the COVID-19 pandemic demonstrated the demand for supporting decision instruments and recommendations in case tertiary triage is needed. COVID-19 patients mainly present sequentially, not parallelly, and therefore ex-post triage scenarios were expected to be more likely than ex-ante ones. Decision-makers in these scenarios may be highly susceptible to second victim and moral injury effects, so that reliable and ethically justifiable algorithms would have been needed in case of overwhelming critical cases.To gather basic information about a potential tertiary triage instrument, we designed a three-dimensional instrument developed by an expert group using the Delphi technique. The instrument focused on three parameters: 1) estimated chance of survival, 2) estimated prognosis of regaining autonomy after treatment, and 3) estimated length of stay in the ICU. To validate and test the instrument, we conducted an anonymous online survey in 5 German hospitals addressing physicians that would have been in charge of decision-making in the case of a mass infection incident. Of about 80 physicians addressed, 47 responded. They were presented with 16 fictional ICU case vignettes (including 3 doublets) which they had to score using the three parameters of the instrument.We detected a good construct validity (Cronbach\'s Alpha 0.735) and intra-reliability (p < 0.001, Cohens Kappa 0.497 to 0.574), but a low inter-reliability (p < 0.001, Cohen\'s Kappa 0.252 to 0.327) for the three parameters. The best inter-reliability was detected for the estimated length of stay in the ICU. Further analysis revealed concerns in assessing the prognosis of the potentially remaining autonomy, especially in patients with only physical impairment.In accordance with German recommendations, we concluded that single-rater triage (which might happen in stressful and highly resource-limited situations) should be avoided to ensure patient and health care provider safety. Future work should concentrate on reliable and valid group decision instruments and algorithms and question whether the chance of survival as a single triage parameter should be complemented with other parameters, such as the estimated length of stay in the ICU.

    康复服务提供者在做出临床决定时必须考虑预后因素,其中包括使用这些因素作为优先级标准。这项研究的目的是根据与等待门诊专业康复服务的轻度创伤性脑损伤(mTBI)患者的持续症状相关的预后因素,就患者优先排序标准达成共识。
    我们进行了一项涉及临床医生的德尔菲调查,研究人员,决策者,和病人。在调查之前,我们介绍了系统综述的结果,总结了与脑震荡后症状相关的预后因素的证据.
    两轮后,17名专家就纳入12项优先排序标准达成共识:急性应激障碍,焦虑和抑郁,基线精神和身体健康,创伤后的功能影响和日常习惯的困难,接受服务的动机,多发性脑震荡,以前的神经问题,创伤后应激障碍,睡眠质量,返回工作失败,躯体投诉,自杀意念.
    医疗保健利益相关者必须考虑广泛的因素来指导临床决策,包括获得护理和患者优先次序。这项研究表明,Delphi技术可用于就等待门诊专业康复服务的mTBI患者的此类决定达成共识。
    Rehabilitation service providers must take into account prognostic factors when making clinical decisions, which includes using these factors as prioritization criteria. The goal of this study was to establish consensus on patient prioritization criteria based on prognostic factors related to persistent symptoms for patients with mild traumatic brain injury (mTBI) waiting for outpatient specialized rehabilitation services.
    We conducted a Delphi survey involving clinicians, researchers, decision makers, and patients. Before the survey, we presented the results of an overview of systematic reviews summarizing the evidence on prognostic factors related to post-concussion symptoms.
    After two rounds, the 17 experts reached consensus on the inclusion of 12 prioritization criteria: acute stress disorder, anxiety and depression, baseline mental and physical health, functional impacts and difficulties in performing daily habits after the trauma, motivation to receive services, multiple concussions, prior neurological problems, PTSD, quality of sleep, return to work failures, somatic complaints, suicidal ideation.
    Healthcare stakeholders must consider a wide range of factors to guide clinical decision-making, including about access to care and patient prioritization. This study shows that the Delphi technique can be used to reach consensus on such decisions regarding patients with mTBI who are waiting for outpatient specialized rehabilitation services.

    目的:我们旨在结合全球疾病负担(GBD)研究数据和当地数据,以确定在新西兰奥特亚罗(新西兰)的案例研究国家中预防心血管疾病(CVD)的最优先干预领域。
    方法:使用“GBD结果工具”从GBD中提取NZ中CVD的危险因素数据。“我们根据对健康负担大小(残疾调整生命年[DALYs])的考虑,然后通过特定领域的干预措施,实现了最高的健康收益和成本节约,对风险因素领域进行了优先排序。
    结果:根据DALYs中CVD健康负担的大小,五个优先考虑的风险因素领域是:高收缩压(84,800DALYs;2019年5400例死亡),然后是饮食风险因素,然后高低密度脂蛋白胆固醇,然后是高BMI,然后是烟草(30,400DALYs;1400例死亡)。但是,如果决策者旨在从已经研究的具体干预措施中最大限度地提高健康收益和节约成本,然后他们会倾向于饮食风险域(例如,水果和蔬菜补贴加上糖税的总和估计可节省894,000个健康调整后的生命年,并节省了110亿美元的卫生系统成本;两者均为3%的贴现率)。确定优先次序的其他潜在考虑因素包括总健康收益的潜力,包括非心血管疾病健康损失,以及毛利人(土著)实现相对更大的人均健康收益以减少健康不平等的潜力。
    结论:我们能够展示如何使用GBD和国家/地区数据的混合对CVD风险因素领域进行系统的优先排序。如果政策制定者只关注健康损失的大小,那么解决高收缩压将是排名最高的领域。但是,如果决策者希望使用评估的干预措施来最大程度地提高健康收益和节省成本,饮食干预将被优先考虑,例如,食品税和补贴。
    We aimed to combine Global Burden of Disease (GBD) Study data and local data to identify the highest priority intervention domains for preventing cardiovascular disease (CVD) in the case study country of Aotearoa New Zealand (NZ).
    Risk factor data for CVD in NZ were extracted from the GBD using the \"GBD Results Tool.\" We prioritized risk factor domains based on consideration of the size of the health burden (disability-adjusted life years [DALYs]) and then by the domain-specific interventions that delivered the highest health gains and cost-savings.
    Based on the size of the CVD health burden in DALYs, the five top prioritized risk factor domains were: high systolic blood pressure (84,800 DALYs; 5400 deaths in 2019), then dietary risk factors, then high LDL cholesterol, then high BMI and then tobacco (30,400 DALYs; 1400 deaths). But if policy-makers aimed to maximize health gain and cost-savings from specific interventions that have been studied, then they would favor the dietary risk domain (e.g., a combined fruit and vegetable subsidy plus a sugar tax produced estimated lifetime savings of 894,000 health-adjusted life years and health system cost-savings of US$11.0 billion; both 3% discount rate). Other potential considerations for prioritization included the potential for total health gain that includes non-CVD health loss and potential for achieving relatively greater per capita health gain for Māori (Indigenous) to reduce health inequities.
    We were able to show how CVD risk factor domains could be systematically prioritized using a mix of GBD and country-level data. Addressing high systolic blood pressure would be the top ranked domain if policy-makers focused just on the size of the health loss. But if policy-makers wished to maximize health gain and cost-savings using evaluated interventions, dietary interventions would be prioritized, e.g., food taxes and subsidies.

    以生精小管的生发上皮不完全发育为特征,睾丸发育不全(TH)导致精子浓度降低,精子和无精子症的形态学变化增加。处置受影响的公牛造成的经济损失降低了肉类生产系统的效率。进行了全基因组关联研究和功能分析,以鉴定与Nellore牛中TH相关的基因组窗口和潜在的位置候选基因。来自207,195只动物和基因型的表型和谱系数据(461,057单核苷酸多态性,本研究使用了来自17,326个父系的SNP)。TH被评估为在18个月大时测量的二元性状。通过使用双性状分析评估了由阴囊周长选择引起的TH的可能相关响应。因此,通过在贝叶斯方法中拟合线性阈值动物模型来计算估计的育种值.使用加权单步基因组BLUP方法估计SNP效应。选择了20个相邻SNP的12个非重叠窗口,这些窗口解释了超过1%的加性遗传变异,用于候选基因注释。候选基因的功能和基因优先级分析鉴定的基因(KHDRBS3,GPX5,STAR,ERLIN2),由于它们在精子发生过程中的已知作用,它们可能在TH的表达中起重要作用,类固醇的合成和脂质代谢。
    Characterized by the incomplete development of the germinal epithelium of the seminiferous tubules, Testicular hypoplasia (TH) leads to decreased sperm concentration, increased morphological changes in sperm and azoospermia. Economic losses resulting from the disposal of affected bulls reduce the efficiency of meat production systems. A genome-wide association study and functional analysis were performed to identify genomic windows and the underlying positional candidate genes associated with TH in Nellore cattle. Phenotypic and pedigree data from 207,195 animals and genotypes (461,057 single nucleotide polymorphism, SNP) from 17,326 sires were used in this study. TH was evaluated as a binary trait measured at 18 months of age. A possible correlated response on TH resulting from the selection for scrotal circumference was evaluated by using a two-trait analysis. Thus, estimated breeding values were calculated by fitting a linear-threshold animal model in a Bayesian approach. The SNP effects were estimated using the weighted single-step genomic BLUP method. Twelve non-overlapping windows of 20 adjacent SNP that explained more than 1% of the additive genetic variance were selected for candidate gene annotation. Functional and gene prioritization analysis of the candidate genes identified genes (KHDRBS3, GPX5, STAR, ERLIN2), which might play an important role in the expression of TH due to their known roles in the spermatogenesis process, synthesis of steroids and lipid metabolism.

    目的:该项目的目的是在Cochrane系统评价(CSR)中发现妇科证据传播方面的差距和研究浪费。
    方法:一项关于Cochrane妇科和生育(CGF)组专门注册的随机对照试验(RCT)的横断面研究。我们纳入了良性妇科疾病的试验,发表于2010年和2011年。这些试验是匹配的,根据病情和治疗,现有的Cochrane评论。分析了未匹配的试验,以优先考虑新的评论标题。
    结果:从CGF专业注册中心导出740项试验后,我们发现,如果更新了现有的CSR,则可以将192(26%)包括在现有的CSR中,而230项试验(32%)与任何评论标题不匹配,从这些,我们开发了21个新的评论标题。相关的“未使用”试验数量最多的主题是“用于更年期症状的植物和草药提取物”。
    结论:我们发现,在2010年和2011年发表的良性妇科试验中,有三分之一没有相关的CSR。在从无与伦比的试验中确定新主题后,我们开发了新的CSR头衔。这项研究确定了女性妇科问题的证据差距。
    OBJECTIVE: The aim of this project was to identify gaps and research waste in the dissemination of gynecology evidence in Cochrane systematic reviews (CSRs).
    METHODS: A cross-sectional study of the Cochrane Gynecology and Fertility (CGF) Group\'s specialized register of randomized controlled trials (RCTs). We included trials on benign gynecological conditions, published in 2010 and 2011. These trials were matched, by the condition and treatment, to existing Cochrane reviews. Unmatched trials were analysed to prioritize new review titles.
    RESULTS: After exporting 740 trials from the CGF specialized register, we found that 192 (26%) could be included in an existing CSR if it was updated, whereas 230 trials (32%) were not matched to any review title, and from these, we developed 21 new review titles. The topic with the largest number of associated \'unused\' trials was \'Plant and herbal extracts for symptoms of menopause\'.
    CONCLUSIONS: We found that a third of the benign gynecology trials published in 2010 and 2011 had no associated CSR. After identifying new topics from unmatched trials, we developed new CSR titles. This study identified the gaps in the evidence for women with gynecological problems.
