    背景:最近的研究表明,与没有这种脆弱性的妇女相比,患有精神疾病的妇女意外怀孕的可能性更高。尽管了解这个群体的计划生育决策很重要,缺乏定性的调查。这项研究探讨了患有精神疾病的妇女的计划生育决定。
    方法:利用定性方法,有目的的抽样进行了三个焦点小组讨论:有意外怀孕史的妇女(N=3),没有孩子的妇女(N=5),和有预期怀孕史的妇女(N=9),所有这些人都有自我报告的精神疾病。利用专题框架分析,我们调查了主题\"过去的阴影,“反映过去的经验,和“未来的阴影,“反映未来的想象力,建立在现有的“叙事框架”上。\"
    结果:叙事框架为了解患有精神疾病的妇女的计划生育奠定了基础。焦点小组讨论的回顾性维度为关于敏感话题的反思叙述提供了机会,揭示后悔的情绪,悲伤和救济。童年创伤,不良事件,不充分的育儿丰富了“过去的阴影”。“现在的阴影”被确定为一个新颖的主题,解决精神疾病和精神稳定情绪的意识。社会影响,污名,对传播精神疾病的担忧在未来的阴影下塑造了未来的想象力。
    结论:这项研究揭示了患有精神疾病的妇女的计划生育决策可能是复杂的,以过去经验和社会影响在这个样本中的持久影响为标志。这些细致入微的见解强调了为患有精神疾病的女性提供量身定制的支持的必要性。
    最近的研究表明,患有精神疾病的女性更有可能经历意外怀孕。然而,根本原因还没有完全理解。了解这些原因对于提供更好的医疗保健很重要。我们的研究探索了患有精神疾病的女性如何做出关于计划生育的决定。我们与不同的女性群体进行了对话-意外怀孕的女性,没有孩子的女人,和预期怀孕的妇女-通过焦点小组讨论。我们与荷兰心理健康组织MIND合作,以捕捉不同的意见。确定并组织了讨论中的关键主题和类别。我们发现了四个主要主题:“过去的阴影”展示了过去的事件,创伤,缺乏育儿知识影响计划生育。"当下的阴影"透露了对计划生育的不同感受,意识到精神疾病的重要性,和决策的不确定性。“未来的阴影”包括关于成为母亲的想法,社会影响的影响,以及对精神疾病传承的担忧。“对决定的反思”展示了精神疾病,做母亲的经历,和遗憾的感觉,悲伤和宽慰影响了计划生育的决定。总之,我们的研究强调了患有精神疾病的女性计划生育决策的复杂性.过去的经历和社会影响,比如耻辱,发挥很大的作用。这些见解表明,需要为患有精神疾病的妇女提供个性化的计划生育支持。
    BACKGROUND: Recent studies revealed an elevated likelihood of unintended pregnancies among women with psychiatric disorders compared to their counterparts without such vulnerability. Despite the importance of understanding family planning decision-making in this group, qualitative inquiries are lacking. This study explored family planning decisions among women with psychiatric disorders.
    METHODS: Utilizing a qualitative approach, three focus group discussions were conducted with purposive sampling: women with a history of unintended pregnancies (N = 3), women without children (N = 5), and women with a history of intended pregnancies (N = 9), all of whom had self-reported psychiatric disorders. Using thematic framework analysis, we investigated the themes \"Shadow of the past,\" reflecting past experiences, and \"Shadow of the future,\" reflecting future imaginaries, building upon the existing \"Narrative Framework.\"
    RESULTS: The Narrative Framework formed the foundation for understanding family planning among women with psychiatric disorders. The retrospective dimension of focus group discussions provided opportunities for reflective narratives on sensitive topics, revealing emotions of regret, grief and relief. Childhood trauma, adverse events, and inadequate parenting enriched the \"Shadow of the past\". The \"Shadow of the present\" was identified as a novel theme, addressing awareness of psychiatric disorders and emotions toward psychiatric stability. Social influences, stigma, and concerns about transmitting psychiatric disorders shaped future imaginaries in the shadow of the future.
    CONCLUSIONS: This study enlightens how family planning decision-making in women with psychiatric disorders might be complex, as marked by the enduring impact of past experiences and societal influences in this sample. These nuanced insights underscore the necessity for tailored support for women with psychiatric disorders.
    Recent studies show that women with psychiatric disorders are more likely to experience unintended pregnancies. However, the underlying reasons are not fully understood. Understanding those reasons is important to provide better healthcare. Our study explored how women with psychiatric disorders make decisions about family planning.We had conversations with different groups of women—women with unintended pregnancies, women without children, and women with intended pregnancies—through focus group discussions. We partnered with the Dutch mental health organization MIND to capture diverse opinions. Key themes and categories in the discussions were identified and organized.We found four main themes: \"Shadow of the past\" showed how past events, trauma, and lack of knowledge about parenting affect family planning. \"Shadow of the present\" revealed different feelings about family planning, the importance of the awareness of psychiatric disorders, and uncertainty about decisions. \"Shadow of the future\" included thoughts about becoming a mother, the impact of social influences, and concerns about passing on psychiatric disorders. \"Reflections on the decision\" showed how psychiatric disorders, experiences with motherhood, and feelings of regret, grief and relief had an influence on family planning decisions.In conclusion, our study highlighted the complexity of family planning decisions for women with psychiatric disorders. Past experiences and societal influences, like stigma, play a big role. These insights show the need for personalized family planning support for women with psychiatric disorders.

    背景:腹膜癌(PC)在晚期妇科和胃肠道癌症患者中很常见。经常,患有PC的患者接受姑息性手术或手术以控制疾病相关的并发症和副作用.然而,关于这些程序的患者和家庭护理人员决策过程的数据有限。因此,我们试图描述选择进行姑息性外科手术的PC患者及其家庭护理人员的决策经验.
    方法:我们对BOLSTER试点随机对照试验中收集的定性数据进行了二次分析,对急性住院和姑息治疗后的PC患者及其护理人员进行护士主导的远程医疗干预。两个研究小组的参与者都在半结构化访谈中描述了他们的经历。我们重新分析了编码的定性数据,重点是了解使用常规内容分析围绕姑息性手术和程序的决策经验。
    结果:来自32名参与者的访谈,23名患者和9名护理人员,进行了分析。参与者报告说,他们的决策因疾病的不确定性和明确的愿望而复杂化,与外科和内科肿瘤团队的有效沟通。参与者要求提供更多有关姑息治疗对其日常生活影响的信息。一些人还指出,如果没有更好的理解,患者和家庭照顾者目标与姑息治疗之间的不一致可能会无意中增加痛苦.
    结论:与患者目标和偏好相关的讨论可以提高PC患者及其护理人员的治疗决策质量。未来的研究应该测试干预措施,以改善晚期癌症患者对姑息性手术和手术的了解和决策。
    BACKGROUND: Peritoneal carcinomatosis (PC) is common in patients with advanced gynecologic and gastrointestinal cancers. Frequently, patients with PC undergo palliative surgery or procedures to manage disease-related complications and side effects. However, there are limited data regarding patients\' and family caregivers\' decision-making processes about these procedures. Thus, we sought to describe the decision-making experiences of patients with PC who elect to pursue palliative surgical procedures and their family caregivers.
    METHODS: We conducted a secondary analysis of qualitative data collected during a pilot randomized controlled trial of BOLSTER, a nurse-led telehealth intervention for patients with PC and their caregivers after an acute hospitalization and palliative procedure. Participants in both study arms described their experiences in semi-structured interviews. We re-analyzed coded qualitative data with a focus on understanding decision-making experiences surrounding palliative surgery and procedures using conventional content analysis.
    RESULTS: Interviews from 32 participants, 23 patients and 9 caregivers, were analyzed. Participants reported their decision-making was complicated by illness uncertainty and a desire for clear, effective communication with surgical and medical oncology teams. Participants requested more information about the impact of palliative procedures on their daily life. Several also noted that, without improved understanding, a misalignment between patient and family caregiver goals and palliative procedures may inadvertently increase suffering.
    CONCLUSIONS: Discussions related to patients\' goals and preferences can improve the quality of treatment decision-making in patients with PC and their caregivers. Future research should test interventions to improve advanced cancer patients\' illness understanding and decision-making surrounding palliative surgery and procedures.

    海马依赖性记忆系统和纹状体依赖性记忆系统根据成人的反馈时间调节强化学习,但他们在开发过程中的贡献仍不清楚。在一项为期两年的纵向研究中,6至7岁的儿童执行强化学习任务,在该任务中,他们立即收到反馈,或者在他们的回应后有短暂的延迟。儿童的学习被发现是敏感的反馈定时调制在他们的反应时间和逆温度参数,量化价值导向决策。他们展示了朝着更优化的基于价值的学习的纵向改进,它们的海马体积显示出延长的成熟。更好的延迟模型衍生学习与较大的海马体积纵向共变,符合成人文学。相比之下,儿童较大的纹状体体积与较好的即时和延迟模型纵向学习相关.这些发现表明,第一次,早期海马对儿童中期强化学习动态发展的贡献,与成人相比,神经分化较少,合作记忆系统更多。
    The hippocampal-dependent memory system and striatal-dependent memory system modulate reinforcement learning depending on feedback timing in adults, but their contributions during development remain unclear. In a 2-year longitudinal study, 6-to-7-year-old children performed a reinforcement learning task in which they received feedback immediately or with a short delay following their response. Children\'s learning was found to be sensitive to feedback timing modulations in their reaction time and inverse temperature parameter, which quantifies value-guided decision-making. They showed longitudinal improvements towards more optimal value-based learning, and their hippocampal volume showed protracted maturation. Better delayed model-derived learning covaried with larger hippocampal volume longitudinally, in line with the adult literature. In contrast, a larger striatal volume in children was associated with both better immediate and delayed model-derived learning longitudinally. These findings show, for the first time, an early hippocampal contribution to the dynamic development of reinforcement learning in middle childhood, with neurally less differentiated and more cooperative memory systems than in adults.

    背景:调查表明临床指南的执行水平较低,尽管它们旨在提高治疗质量和患者安全。哪些准则建议没有得到遵循,为什么还有待分析。在这项研究中,我们调查了在非心脏手术前的术前麻醉评估领域遵循的欧洲和国家指南的比例.
    方法:我们在一家德国大学医院进行了这项单中心回顾性观察研究,该研究借助软件将指南进行逻辑链接,从而可以从患者数据中得出个性化建议。我们纳入了2003年患者的常规日志,这些患者在2018年6月至2020年6月期间访问了我们的麻醉前门诊诊所,并将实际进行的术前检查与软件发布的建议进行了比较。我们描述性地分析了指南建议的未进行检查的数据,以及即使指南建议未涵盖也已进行检查的数据。本研究中检查的指南是2018年ESAIC指南,用于对接受非心脏手术的成人进行术前评估。2014年ESC/ESA非心脏手术指南和2017年德国关于非心胸外科手术术前评估的建议.
    结果:进行的心电图(78.1%)和心脏负荷成像测试(86.1%)表明指南依从性最高。更高的依从率与更高的ASA评分相关(ASAI:23.7%,ASAII:41.1%,ASAIII:51.8%,ASAIV:65.8%,P<0.001),较低的BMI和年龄>65岁。高危手术的依从性(60.5%)高于中危手术(46.5%)或低危手术(44.6%)(P<0.001)。67.2%的术前技术和实验室检查未纳入指南建议。
    结论:术前评估中的指南依从性仍有改进的空间。许多人进行了术前检查,尤其是实验室测试,指南不推荐,可能会导致不必要的费用。不遵守准则的原因可能是准则和组织问题的复杂性。基于软件的决策支持工具可能会有所帮助。
    背景:ClinicalTrials.govIDNCT04843202。
    BACKGROUND: Surveys suggest a low level of implementation of clinical guidelines, although they are intended to improve the quality of treatment and patient safety. Which guideline recommendations are not followed and why has yet to be analysed. In this study, we investigate the proportion of European and national guidelines followed in the area of pre-operative anaesthetic evaluation prior to non-cardiac surgery.
    METHODS: We conducted this monocentric retrospective observational study at a German university hospital with the help of software that logically links guidelines in such a way that individualised recommendations can be derived from a patient\'s data. We included routine logs of 2003 patients who visited our pre-anaesthesia outpatient clinic between June 2018 and June 2020 and compared the actual conducted pre-operative examinations with the recommendations issued by the software. We descriptively analysed the data for examinations not performed that would have been recommended by the guidelines and examinations that were performed even though they were not covered by a guideline recommendation. The guidelines examined in this study are the 2018 ESAIC guidelines for pre-operative evaluation of adults undergoing elective non-cardiac surgery, the 2014 ESC/ESA guidelines on non-cardiac surgery and the German recommendations on pre-operative evaluation on non-cardiothoracic surgery from the year 2017.
    RESULTS: Performed ECG (78.1%) and cardiac stress imaging tests (86.1%) indicated the highest guideline adherence. Greater adherence rates were associated with a higher ASA score (ASA I: 23.7%, ASA II: 41.1%, ASA III: 51.8%, ASA IV: 65.8%, P < 0.001), lower BMI and age > 65 years. Adherence rates in high-risk surgery (60.5%) were greater than in intermediate (46.5%) or low-risk (44.6%) surgery (P < 0.001). 67.2% of technical and laboratory tests performed preoperatively were not covered by a guideline recommendation.
    CONCLUSIONS: Guideline adherence in pre-operative evaluation leaves room for improvement. Many performed pre-operative examinations, especially laboratory tests, are not recommended by the guidelines and may cause unnecessary costs. The reasons for guidelines not being followed may be the complexity of guidelines and organisational issues. A software-based decision support tool may be helpful.

    背景:抑郁症中奖赏敏感性降低的神经和行为指数之间的联系机制,特别是在儿童中,仍然不清楚。奖励积极性(RewP),奖励处理的神经指数,一直与抑郁症有关。分别,最近在行为数据上使用漂移扩散模型(DDM)的研究已经描绘了奖励敏感性的计算指数。因此,本研究调查了RewP在不同症状严重程度下预测小儿抑郁症时是否是基于DDM的奖励处理指数的神经介质.
    方法:166名女孩的社区样本,8至14岁,完成两项任务。第一个是奖励猜测任务,使用脑电图计算RewP;第二个是基于概率奖励的决策任务。在第二个任务中,将DDM分析应用于行为数据,以量化累积奖励相关证据的效率(漂移率)和对不同奖励选择的潜在基线偏差(起点)。使用自我报告儿童抑郁量表(CDI)测量抑郁严重程度。
    结果:RewP与漂移率相关,但不是起点偏差,走向更有回报的选择。此外,RewP完全介导了向更多回报选择的较慢漂移率与较高抑郁症状严重程度之间的关联。
    结论:我们的研究结果表明,在抑郁症状严重程度较高的儿童和青少年中,神经对奖赏的敏感性降低可能是一种神经机制,在这种情况下,为奖励处理的神经指数和计算指数之间的关系提供了新的见解。
    BACKGROUND: The mechanisms linking neural and behavioral indices of reduced reward sensitivity in depression, particularly in children, remain unclear. Reward positivity (RewP), a neural index of reward processing, has been consistently associated with depression. Separately, recent studies using the drift-diffusion model (DDM) on behavioral data have delineated computational indices of reward sensitivity. Therefore, the present study examined whether RewP is a neural mediator of DDM-based indices of reward processing in predicting pediatric depression across varying levels of symptom severity.
    METHODS: A community sample of 166 girls, aged 8 to 14 years, completed two tasks. The first was a reward guessing task from which RewP was computed using electroencephalography; the second was a probabilistic reward-based decision-making task. On this second task, DDM analysis was applied to behavioral data to quantify the efficiency of accumulating reward-related evidence (drift rate) and potential baseline bias (starting point) towards the differently rewarded choices. Depression severity was measured using the self-report Children\'s Depression Inventory (CDI).
    RESULTS: RewP was correlated with drift rate, but not starting point bias, towards the more rewarded choice. Furthermore, RewP completely mediated the association between a slower drift rate towards the more rewarded option and higher depression symptom severity.
    CONCLUSIONS: Our findings suggest that reduced neural sensitivity to reward feedback might be a neural mechanism underscoring behavioral insensitivity to reward in children and adolescents with higher depression symptom severity, offering novel insights into the relationship between neural and computational indices of reward processing in this context.

    目的:本研究探讨了选择实验性主动监测(而不是标准手术)治疗食管癌的患者及其伴侣或主要护理人员的决策经验。
    方法:17对夫妇参与。对夫妻的共同经历以及他们的个人经历进行了半结构化访谈。使用调整后的对照偏好量表评估治疗决策过程中的首选和感知角色。使用视觉模拟量表测量对治疗决策的感知影响。
    结果:夫妇在决策过程中反映为积极的合作,患者通过做出最终决定来保留他们的自主权,和合作伙伴提供情感支持。夫妇报告了有关不同医院和医疗保健提供者之间治疗方法的大量信息,有时甚至相互矛盾。
    结论:患者经常让他们的伴侣参与决策,他们报告说,这增强了他们应对疾病的能力。决策过程中的数量和有时相互冲突的信息提供了改进的机会。
    结论:夫妇可以从对治疗过程中的期望的概述中受益。如果主动监测在未来成为既定的治疗选择,提供此类概述和一致的信息应该变得更加精简。
    OBJECTIVE: This study explored the decision-making experiences of patients and their partners or primary caregiver who opted for experimental active surveillance (instead of standard surgery) for the treatment of esophageal cancer.
    METHODS: Seventeen couples participated. Semi-structured interviews were conducted on couples\' joint experiences as well as their individual experiences. Preferred and perceived role in the treatment decision-making process was assessed using the adjusted version of the Control Preferences Scale, and perceived influence on the treatment decision was measured using a visual analog scale.
    RESULTS: Couples reflected on the decision-making process as a positive collaboration, where patients retain their autonomy by making the final decision, and partners offer emotional support. Couples reported about an overwhelming amount and sometimes conflicting information about treatments among different hospitals and healthcare providers.
    CONCLUSIONS: Patients often involve their partner in decision-making, which they report to have enhanced their ability to cope with the disease. The amount and sometimes conflicting information during the decision-making process provide opportunities for improvement.
    CONCLUSIONS: Couples can benefit from an overview of what they can expect during treatment course. If active surveillance becomes an established treatment option in the future, provision of such overviews and consistent information should become more streamlined.

    医疗保健正处于一个转折点。我们正在从原始医学转向精准医学,数字医疗系统正在促进这一转变。通过为临床医生提供每位患者的详细信息以及在护理点为决策提供分析支持,数字健康技术正在开启精准医疗的新时代。基因组数据还为临床医生提供了可以提高诊断准确性和及时性的信息,优化处方,和目标风险降低策略,所有这些都是精准医疗的关键要素。然而,基因组数据主要被视为诊断信息,没有被常规地整合到电子病历的临床工作流程中.基因组数据的使用具有精确医学的巨大潜力;然而,由于基因组数据与常规实践中收集的信息根本不同,在数字健康环境中使用此信息需要特别考虑。本文概述了基因组数据与电子记录整合的潜力,以及这些数据如何实现精准医疗。
    Health care is at a turning point. We are shifting from protocolized medicine to precision medicine, and digital health systems are facilitating this shift. By providing clinicians with detailed information for each patient and analytic support for decision-making at the point of care, digital health technologies are enabling a new era of precision medicine. Genomic data also provide clinicians with information that can improve the accuracy and timeliness of diagnosis, optimize prescribing, and target risk reduction strategies, all of which are key elements for precision medicine. However, genomic data are predominantly seen as diagnostic information and are not routinely integrated into the clinical workflows of electronic medical records. The use of genomic data holds significant potential for precision medicine; however, as genomic data are fundamentally different from the information collected during routine practice, special considerations are needed to use this information in a digital health setting. This paper outlines the potential of genomic data integration with electronic records, and how these data can enable precision medicine.

    背景:股骨颈骨折(FNF)约占全身所有骨折的3.58%,呈现逐年增长的趋势。根据一项调查,1990年,全世界男性和女性的髋部骨折总数分别约为338,000和917,000.在中国,FNFs占髋部骨折的48.22%。目前,已经对FNF患者的出院后死亡率和死亡风险进行了许多研究.然而,目前尚无关于重症监护病房重症FNF患者院内死亡率及其影响因素的确切研究.
    目的:在本文中,采用3种机器学习方法构建重症监护病房患者院内死亡预测模型,以辅助临床医师早期临床决策。
    方法:使用来自重症监护医学信息集市III的FNF患者的信息进行回顾性分析。在使用合成少数过采样技术算法平衡数据集之后,患者随机分为70%的训练集和30%的测试集进行开发和验证,分别,预测模型。随机森林,极端梯度增强,并以医院死亡为结果构建反向传播神经网络预测模型。使用接收器工作特性曲线下的面积评估模型性能,准确度,精度,灵敏度,和特异性。通过与传统logistic模型的对比,验证了模型的预测价值。
    结果:共选择366名FNFs患者,其中48例(13.1%)住院死亡。通过将数据集与院内死亡组和生存组的平衡为1:1来获得来自636名患者的数据。3种机器学习模型表现出很高的预测精度,和随机森林的接收器工作特性曲线下的面积,极端梯度增强,和反向传播神经网络分别为0.98、0.97和0.95,均具有比传统逻辑回归模型更高的预测性能。对特征变量的重要性进行排名,对预测患者院内死亡风险有意义的前10个特征变量是简化急性生理学评分II,乳酸,肌酐,性别,维生素D,钙,肌酸激酶,肌酸激酶同工酶,白细胞,和年龄。
    结论:利用机器学习构建的死亡风险评估模型对预测重症患者院内死亡率具有积极意义,为降低院内死亡率、改善患者预后提供有效依据。
    BACKGROUND: Femoral neck fracture (FNF) accounts for approximately 3.58% of all fractures in the entire body, exhibiting an increasing trend each year. According to a survey, in 1990, the total number of hip fractures in men and women worldwide was approximately 338,000 and 917,000, respectively. In China, FNFs account for 48.22% of hip fractures. Currently, many studies have been conducted on postdischarge mortality and mortality risk in patients with FNF. However, there have been no definitive studies on in-hospital mortality or its influencing factors in patients with severe FNF admitted to the intensive care unit.
    OBJECTIVE: In this paper, 3 machine learning methods were used to construct a nosocomial death prediction model for patients admitted to intensive care units to assist clinicians in early clinical decision-making.
    METHODS: A retrospective analysis was conducted using information of a patient with FNF from the Medical Information Mart for Intensive Care III. After balancing the data set using the Synthetic Minority Oversampling Technique algorithm, patients were randomly separated into a 70% training set and a 30% testing set for the development and validation, respectively, of the prediction model. Random forest, extreme gradient boosting, and backpropagation neural network prediction models were constructed with nosocomial death as the outcome. Model performance was assessed using the area under the receiver operating characteristic curve, accuracy, precision, sensitivity, and specificity. The predictive value of the models was verified in comparison to the traditional logistic model.
    RESULTS: A total of 366 patients with FNFs were selected, including 48 cases (13.1%) of in-hospital death. Data from 636 patients were obtained by balancing the data set with the in-hospital death group to survival group as 1:1. The 3 machine learning models exhibited high predictive accuracy, and the area under the receiver operating characteristic curve of the random forest, extreme gradient boosting, and backpropagation neural network were 0.98, 0.97, and 0.95, respectively, all with higher predictive performance than the traditional logistic regression model. Ranking the importance of the feature variables, the top 10 feature variables that were meaningful for predicting the risk of in-hospital death of patients were the Simplified Acute Physiology Score II, lactate, creatinine, gender, vitamin D, calcium, creatine kinase, creatine kinase isoenzyme, white blood cell, and age.
    CONCLUSIONS: Death risk assessment models constructed using machine learning have positive significance for predicting the in-hospital mortality of patients with severe disease and provide a valid basis for reducing in-hospital mortality and improving patient prognosis.

    产品的基本信息,健康,安全,和营养细节,以及食品营销,广告,和晋升,都在包装的食品标签上提供。这项研究是为了评估知识,态度,以及购物者关于食品标签的做法,因为在印度很少有研究,在浦那没有。
    使用经过验证的半结构化问卷对226名参与者进行了横断面研究,其中包括社会人口统计细节和关于他们知识的问题,态度,并在购买包装食品时练习食品标签。定量数据以平均值的形式呈现,标准偏差,平均值的95%置信区间(CI),中位数,和四分位数间距(IQR)。定性数据以数量(N)表示,百分比(%),95%CI的百分比。
    在226名参与者中,163(72.12)知道包装食品上的标签。共有77位(78.32%)参与者阅读了包装食品上的标签。最高零售价(MRP)和有效期是最常见的标签。尽管17.7%的消费者在购买时没有考虑营养成分,能量和蛋白质是最常被考虑的营养素。大多数人(70.35%)错误地认为果汁是健康的。包装食品标签的小字体使30.38%的顾客难以阅读。
    尽管人们对包装食品标签的认识有所提高,一小部分购物者不关心营养信息。与流行的知识相反,大多数人认为包装食品对健康有积极影响。
    UNASSIGNED: The basic product information, health, safety, and nutritional details, as well as food marketing, advertising, and promotion, are all provided on a packed food label. This study was carried out to assess the knowledge, attitude, and practices of the shoppers regarding food labels as there are few studies done in India and none in Pune.
    UNASSIGNED: A cross-sectional study was carried out among 226 participants using a validated semi-structured questionnaire, which consisted of sociodemographic details and questions on their knowledge, attitude, and practice regarding food labels while purchasing a packed food item. Quantitative data are presented in the form of mean, standard deviation, 95% confidence interval (CI) of mean, median, and interquartile range (IQR). Qualitative data are in terms of number (N), percentages (%), and 95% CI of percentage.
    UNASSIGNED: Of the 226 participants, 163 (72.12) were aware of the label on packaged foods. One hundred seventy-seven (78.32%) participants in all read the label on the packaged food. The maximum retail price (MRP) and expiration date were the most frequent labels sought. Although 17.7% of consumers did not consider nutrient composition when making a purchase, energy and protein were the most often considered nutrients. The majority (70.35%) falsely believed that juice was healthy. The packed food label\'s tiny font made it difficult to read for 30.38% of the customers.
    UNASSIGNED: Despite the increased awareness about packed food labeling, a fraction of shoppers were not concerned about nutritional information. In contrast to the prevailing knowledge, the majority believes packed food has a positive effect on health.

    许多日常决定,包括那些关于我们健康的,财政和环境,涉及在较小但迫在眉睫的奖励之间进行选择(例如,现在20欧元)和后来但更大的奖励(例如,每月40欧元)。可以使用延迟折扣任务来测量个人偏好较小的即将到来的奖励而不是较大的延迟奖励的程度。急性压力会引起一系列的生物和心理反应,对个人如何思考未来产生潜在的影响。过程奖励,做出决定,所有这些都可能影响延迟折扣。几项研究表明,个人在压力下更关注即将到来的奖励。这些发现已被用来解释为什么个人在急性压力下做出有害选择。然而,将急性压力与延迟折扣联系起来的证据是模棱两可的。为了解决这种不确定性,我们对11项研究(14项效应)进行了荟萃分析,以系统地量化急性应激对货币延迟贴现的影响.总的来说,我们发现急性压力对延迟折扣没有影响,与对照条件相比(SMD=-0.18,95%CI[-0.57,0.20],p=0.32)。我们还发现参与者的性别都不是,压力源的类型(例如,物理vs.社会心理),也不是货币决策是假设的还是激励的(即货币决策实际上是支付的)缓和了急性压力对货币延迟贴现的影响。我们认为,建立急性压力对延迟贴现所涉及的单独过程的影响,如奖励估价和勘探,将有助于解决该领域的不一致。
    Many everyday decisions, including those concerning our health, finances and the environment, involve choosing between a smaller but imminent reward (e.g., €20 now) and a later but larger reward (e.g., €40 in a month). The extent to which an individual prefers smaller imminent rewards over larger delayed rewards can be measured using delay discounting tasks. Acute stress induces a cascade of biological and psychological responses with potential consequences for how individuals think about the future, process rewards, and make decisions, all of which can impact delay discounting. Several studies have shown that individuals focus more on imminent rewards under stress. These findings have been used to explain why individuals make detrimental choices under acute stress. Yet, the evidence linking acute stress to delay discounting is equivocal. To address this uncertainty, we conducted a meta-analysis of 11 studies (14 effects) to systematically quantify the effects of acute stress on monetary delay discounting. Overall, we find no effect of acute stress on delay discounting, compared to control conditions (SMD = -0.18, 95% CI [-0.57, 0.20], p = 0.32). We also find that neither the gender/sex of the participants, the type of stressor (e.g., physical vs. psychosocial) nor whether monetary decisions were hypothetical or incentivized (i.e. monetary decisions were actually paid out) moderated the impact of acute stress on monetary delay discounting. We argue that establishing the effects of acute stress on the separate processes involved in delay discounting, such as reward valuation and prospection, will help to resolve the inconsistencies in the field.
