Discrimination based on weight status (or weight-related discrimination/stigma) may be related to greater physical and mental health concerns via physiological and psychological phenotypes of stress. Cortisol output, a biomarker of stress, has been measured in relation to weight stigma and weight-related discrimination. This systematic review aims to synthesize existing research on the relationship between weight-related discrimination and cortisol output, evaluate methodological approaches for measuring these constructs, and identify research gaps regarding contextual factors influencing this relationship. A comprehensive search was conducted across multiple databases (PsycINFO, Scopus, ProQuest, and PubMed) from February 1 to July 1, 2024, resulting in 11 eligible studies that examined weight discrimination in relation to cortisol levels. Studies were assessed for quality using the NHLBI Study Quality Assessment Tool, and inter-rater reliability for coding was established at 90 %. The findings revealed a range of sample sizes (45–4341) and diverse participant characteristics, including variations in age, race, and body mass index (BMI). About half (N = 5) of the included studies reported a positive relation between weight stigma and cortisol output. The review also uncovered significant limitations in current methodologies, particularly concerning contextual factors and other marginalized identities, such as socioeconomic status and food insecurity, along with measuring other forms of discrimination in tandem with weight stigma, such as racial discrimination. These findings underscore the need for future research to adopt a more intersectional approach in examining the multifaceted nature of weight stigma and how it relates to a greater stress response in multiple marginalized identities, as well as including longitudinal modeling of weight stigma's impact on biomarkers for stress.
基于体重状况的歧视(或与体重相关的歧视/耻辱)可能通过生理和心理压力表型与更大的身心健康问题相关。皮质醇输出是压力的生物标志物,已经测量了与体重耻辱和体重相关歧视的关系。本系统综述旨在综合有关体重相关歧视与皮质醇输出之间关系的现有研究,评估测量这些结构的方法学方法,并确定影响这种关系的背景因素的研究空白。从2024年2月1日到7月1日,我们在多个数据库(PsycINFO、Scopus、ProQuest和PubMed)中进行了全面的搜索,得出了11项符合条件的研究,研究了体重歧视与皮质醇水平的关系。使用NHLBI研究质量评估工具对研究进行质量评估,并确定编码的评分者间信度为90%。研究结果揭示了样本量的范围(45-4341)和不同的参与者特征,包括年龄、种族和身体质量指数(BMI)的变化。纳入的研究中约有一半(N = 5)报告了体重耻感与皮质醇输出之间的正相关。审查还发现了现有方法的重大局限性,特别是在背景因素和其他边缘化身份方面,如社会经济地位和粮食不安全,以及与体重耻辱相结合的其他形式的歧视,如种族歧视。这些发现强调了未来的研究需要采用更交叉的方法来研究体重耻辱感的多面性,以及它如何与多个边缘化身份的更大压力反应相关,以及包括体重耻辱感对压力生物标志物影响的纵向建模。

Workers’ well-being during viral pandemics and epidemics: A scoping review 病毒大流行和流行病期间工人的福祉:范围审查
IF 2.1 Q3 ENDOCRINOLOGY & METABOLISM Pub Date : 2025-05-01 Epub Date: 2025-03-04 DOI: 10.1016/j.cpnec.2025.100286

Studies have documented workers' well-being during individual pandemics and epidemics. However, there lies a need to summarize worker well-being across crises. Moreover, there is a scarcity of reviews exploring precarious workers' well-being during these crises. Adopting a multidisciplinary perspective via positive psychology's third wave, this scoping review examines positive and negative well-being across diverse occupational groups and situations (e.g., precarious employment) and across crises. Inspired by Ecological Systems Theory, factors at different ecological levels (self, social, workplace, pandemic) relevant to workers' well-being are reviewed. The following questions are addressed: 1) How are virus-related public health crises (i.e., epidemics, pandemics) related to workers' well-being? 2) What resilience and risk factors are associated with workers' well-being in these crises? And 2a) How is the well-being of precarious workers impacted during virus-related public health crises? Of the 2,395 potentially relevant articles published before October 23rd, 2020, 187 were retained. Overall, more research has been conducted on negative than positive well-being. Workers experienced: 1) positive well-being frequently or at moderately high levels overall during pandemics and epidemics, 2) mild to moderate negative well-being during SARS and COVID-19's beginning and high negative well-being during other crises, and 3) high work-related well-being during such crises. Factors at self- (age, gender), social- (social support), workplace- (occupation, frontline status), and pandemic-related (risk/exposure, knowing someone infected/killed by the virus, PPE access) levels were associated with workers' well-being. Although explored infrequently, precarious employment was typically associated with greater negative well-being. Practice- and policy-related recommendations are discussed.
研究记录了工人在个别流行病和流行病期间的福祉。然而,有必要总结危机期间工人的福祉。此外,在这些危机中,探讨不稳定工人福利的评论很少。通过积极心理学的第三波,采用多学科视角,这一范围审查检查了不同职业群体和情况(例如,不稳定的就业)和危机中的积极和消极幸福感。受生态系统理论的启发,在不同的生态水平(自我、社会、工作场所、流行病)与工人的福祉相关的因素进行了审查。处理以下问题:1)与病毒有关的公共卫生危机(即流行病、大流行)与工人的福祉有何关系?2)在这些危机中,哪些适应力和风险因素与工人的幸福感有关?2a)在与病毒相关的公共卫生危机期间,不稳定工人的福祉如何受到影响?在2020年10月23日之前发表的2395篇可能相关的文章中,187篇被保留。总的来说,对消极幸福感的研究多于对积极幸福感的研究。工人经历:1)在大流行和流行病期间经常或总体上处于中高水平的积极幸福感,2)在SARS和COVID-19开始期间轻度至中度的消极幸福感,在其他危机期间高度的消极幸福感,以及3)在此类危机期间与工作相关的高度幸福感。自我因素(年龄、性别)、社会因素(社会支持)、工作场所因素(职业、一线状况)和与大流行相关的因素(风险/接触、认识被病毒感染/死亡的人、获得个人防护装备)水平与工人的福祉相关。虽然很少被研究,但不稳定的就业通常与更大的负面幸福感有关。讨论了与实践和政策相关的建议。

Panic attack symptoms in patients with diabetic peripheral neuropathy 糖尿病周围神经病变患者的惊恐发作症状
IF 2.1 Q3 ENDOCRINOLOGY & METABOLISM Pub Date : 2025-05-01 Epub Date: 2025-04-10 DOI: 10.1016/j.cpnec.2025.100292

Assessment of diabetic peripheral neuropathy (DPN) usually focuses on nerve damage resulting from hyperglycaemia. However, screening for common psychiatric disorders may improve the recognition of psychopathology in patients with DPN.
This epidemiological cohort study aimed to evaluate the prevalence of panic attack symptoms in patients with DPN compared toa control group of healthy individuals without type 2 diabetes mellitusorDPN.Additionally, this study sought to compare the severity of these symptoms between the two groups.The study was conducted via a survey over three years in an accredited practice of physicians at the Medical University-Sofia.
A total of267 participants were included, comprising 83 patients with DPN and 184healthy controls. Both groups completed the Prime-MD Patient Health Questionnaire. The results indicated significant differences between the two study groups(t[127.513] = 3.293; p < 0.01), and patients with DPN had a higher prevalence of panic attack symptoms than those in the control group.Furthermore, significant differences were observed in the severity of panic attack symptoms within the DPN group (t[(81] = 2.017, p < 0.05).Patients who had experienced DPN for more than one year reported more severe symptoms than those who had experienced it for less than oneyear. Our results indicate that the high prevalence of panic attack symptoms inpatients with DPN highlights the need for integrated screening for psychiatric disorders within the overall management plan for diabetes mellitus.
糖尿病周围神经病变(DPN)的评估通常侧重于高血糖引起的神经损伤。然而,对常见精神疾病的筛查可能会提高DPN患者对精神病理的认识。本流行病学队列研究旨在评估惊恐发作症状在DPN患者中的流行程度,并与无2型糖尿病或DPN的健康对照组进行比较。此外,本研究试图比较两组之间这些症状的严重程度。这项研究是通过对索非亚医科大学认可执业医师进行的一项为期三年的调查进行的。共纳入267名参与者,包括83名DPN患者和184名健康对照者。两组都完成了Prime-MD患者健康问卷。结果显示两个研究组之间存在显著差异(t[127.513] = 3.293;p & lt;DPN患者出现惊恐发作症状的发生率高于对照组(0.01)。此外,DPN组惊恐发作症状严重程度差异有统计学意义(t[(81] = 2.017, p <;0.05)。经历DPN超过一年的患者比经历DPN不到一年的患者报告的症状更严重。我们的研究结果表明,DPN患者惊恐发作症状的高发突出了在糖尿病总体管理计划中对精神疾病进行综合筛查的必要性。

Increased inflammation and associated metabolic disturbances have been shown to affect neurotransmitters and brain circuits, contributing to an immunometabolic phenotype of anhedonic depression. To extend our previous findings on relationships between plasma lipids and antidepressant response to anti-cytokine therapy, we explored in secondary analyses whether lipid-related biomarkers similarly predicted change in anhedonia or functional connectivity (FC) in dopamine-rich corticostriatal reward circuitry in medically-stable, depressed patients with a range of inflammation levels (indexed by plasma C-reactive protein [CRP]) who were administered inflammation-targeted therapies. Relationships were examined between baseline lipids (plasma cholesterols, triglycerides and non-esterified fatty acids) and reduction of anhedonia symptoms in Study 1 (n = 60) after three infusions of infliximab or placebo and change in resting-state FC in Study 2 (n = 31) after acute, within-subject challenge with levodopa (L-DOPA) and placebo. A treatment by inflammation interaction revealed lower anhedonia after infliximab versus placebo (F[1,49] = 5.5, p < 0.05) in patients with, but not without, CRP>3 mg/L (n = 27). A composite score of lipid-related biomarkers (with increasing values reflecting higher concentrations) also precited anhedonia response (post-treatment minus baseline) to infliximab (r = −0.46, p < 0.05) but not placebo (r = 0.14, p = 0.56). Lipid scores similarly predicted CRP-related increases in reward circuit FC after L-DOPA (r = 0.53, p < 0.01) but not placebo (r = 0.20, p = 0.34). Responses to infliximab and L-DOPA were strongest in patients with versus without clinically elevated CRP (>3 mg/L) and/or cholesterol (>150 mg/dL)(p < 0.05). Results highlight a role for dyslipidemia in immunometabolic depression, biomarkers of which, together with CRP, have potential to classify patients indicated for therapies that block inflammation or its effects on neurotransmitters like dopamine.
增加的炎症和相关的代谢紊乱已被证明会影响神经递质和脑回路,导致免疫代谢表型的快感缺乏抑郁症。为了扩展我们之前关于血浆脂质与抗抑郁反应对抗细胞因子治疗之间关系的研究结果,我们在二次分析中探索了脂质相关生物标志物是否类似地预测了医学上稳定的、具有一系列炎症水平(以血浆c -反应蛋白[CRP]为指标)的抑郁症患者在接受炎症靶向治疗后,在富含多巴胺的皮质纹状体奖励回路中缺乏或功能连接(FC)的变化。在研究1 (n = 60)中,三次输注英夫利昔单抗或安慰剂后,基线血脂(血浆胆固醇、甘油三酯和非酯化脂肪酸)与快感缺乏症症状的减轻之间的关系,以及在研究2 (n = 31)中,左旋多巴和安慰剂急性刺激后静息状态FC的变化之间的关系。炎症相互作用的治疗显示英夫利昔单抗治疗后快感缺乏症较安慰剂低(F[1,49] = 5.5, p <;CRP>为3 mg/L (n = 27)的患者0.05)。脂质相关生物标志物的综合评分(值越高反映浓度越高)也预测了对英夫利昔单抗的缺乏症反应(治疗后减去基线)(r = - 0.46, p <;0.05),而安慰剂组没有(r = 0.14, p = 0.56)。脂质评分类似地预测左旋多巴后奖赏回路FC与crp相关的增加(r = 0.53, p <;0.01),而安慰剂组没有(r = 0.20, p = 0.34)。英夫利昔单抗和左旋多巴对临床CRP升高(3 mg/L)和/或胆固醇升高(150 mg/dL)的患者的反应最强(p <;0.05)。结果强调了血脂异常在免疫代谢抑郁症中的作用,其生物标志物与CRP一起,有可能对需要阻断炎症或其对多巴胺等神经递质影响的治疗的患者进行分类。

Exploring stress and depressive symptoms in pregnancy and the IL-1β, IL-6, and C-reactive protein pathway: Looking for possible biomarker targets 探索妊娠期压力和抑郁症状及IL-1β、IL-6和c反应蛋白通路:寻找可能的生物标志物靶点
IF 2.1 Q3 ENDOCRINOLOGY & METABOLISM Pub Date : 2025-02-01 Epub Date: 2024-12-29 DOI: 10.1016/j.cpnec.2024.100280

Background

Individuals undergo significant stress throughout pregnancy and are at high risk for depressive symptoms. Elevated stress and depressive symptoms are associated with inflammatory processes and adverse maternal-infant outcomes. However, the biological processes associated with psychosocial outcomes and the maternal immune system remain unclear. As such, we aimed to examine associations among perceived stress, depressive symptoms, salivary IL-1β, IL-6, and CRP levels, and hair and salivary cortisol levels during the second and third trimesters of pregnancy.

Methods

We conducted an ancillary study consisting of 37 pregnant individuals. Participants collected salivary samples and measures of perceived stress and depression at 17–19 weeks, 25–27 weeks, and 32–34 weeks gestation. We collected a one-time hair sample between 36 and 40 weeks. Provided salivary samples were used to detect changes in cortisol, IL-1β, IL-6, and CRP levels. Hair was used to detect changes in cortisol levels throughout pregnancy.

Results

Elevated levels of perceived stress and depressive symptoms are associated with increased salivary CRP levels, respectively (p = 0.0142, p = 0.0008). Salivary and hair cortisol increased significantly throughout the second and third trimesters of pregnancy (p = 0.0004 and p < 0.0001). We also observed variations in IL-6 during pregnancy (p = 0.029) and significant increases between 25 and 27 weeks (p = 0.016).

Conclusion

Salivary samples may provide a non-invasive measurement of alterations in cytokine and cortisol levels in pregnant individuals reporting elevated stress and depressive symptoms. These may be candidate biomarkers for mechanistic study possibly aiding providers in early detection of deleterious immunological processes which could result in adverse maternal-infant outcomes.
背景:个体在怀孕期间承受着巨大的压力,并且抑郁症状的风险很高。应激升高和抑郁症状与炎症过程和不良母婴结局相关。然而,与心理社会结果和母体免疫系统相关的生物学过程仍不清楚。因此,我们的目的是研究妊娠中期和晚期感知压力、抑郁症状、唾液IL-1β、IL-6和CRP水平以及毛发和唾液皮质醇水平之间的关系。方法:我们对37名孕妇进行了一项辅助研究。参与者在妊娠17-19周、25-27周和32-34周收集唾液样本和感知压力和抑郁的测量。我们收集了36到40周的一次性头发样本。提供的唾液样本用于检测皮质醇、IL-1β、IL-6和CRP水平的变化。头发被用来检测整个怀孕期间皮质醇水平的变化。结果:感知压力和抑郁症状水平升高分别与唾液CRP水平升高相关(p = 0.0142, p = 0.0008)。唾液和毛发皮质醇在妊娠中期和晚期显著升高(p = 0.0004和p)。结论:唾液样本可以提供一种非侵入性的测量方法,用于报告压力升高和抑郁症状的孕妇的细胞因子和皮质醇水平的变化。这些可能是机制研究的候选生物标志物,可能有助于提供者早期发现可能导致不良母婴结局的有害免疫过程。

This study aimed to investigate the effects of social isolation stress during pregnancy on maternal behavior and associated neurochemical changes in the hippocampus of rats.
Twenty female Sprague-Dawley rats were randomly assigned to either a group housing (two rats per cage: control group) or a social isolation stress group (one rat per cage: SI group) during pregnancy. At the end of the study, we assessed the levels of BDNF, corticosterone, and GABAARα1 in the hippocampus of the maternal brain, along with evaluating the endurance, integration, and emotional aspects of maternal behavior. Results indicated that social isolation stress significantly decreased maternal endurance, integration, and emotionality (self-calming) of maternal behavior. Concurrently, blood and the hippocampal corticosterone concentration significantly increased, while BDNF concentration significantly decreased in the SI stress group compared to controls. Moreover, GABAARα1 mRNA expression was significantly decreased in the hippocampus of socially isolated rats. These findings demonstrate that social isolation stress during pregnancy profoundly impacts maternal behaviors in rats, including endurance, integration, and self-soothing. The altered concentration of corticosterone and BDNF, and GABAARα1 mRNA expression in the hippocampus of social isolation group suggests disruptions in stress response regulation and synaptic plasticity during pregnancy to form normal maternal behavior.
本研究旨在探讨妊娠期社会隔离应激对母性行为及海马神经化学变化的影响。20只雌性Sprague-Dawley大鼠在怀孕期间被随机分配到一组(每个笼子2只大鼠:对照组)或一个社会隔离应激组(每个笼子1只大鼠:SI组)。在研究结束时,我们评估了母体大脑海马区的BDNF、皮质酮和GABAARα1水平,同时评估了母体行为的耐力、整合和情感方面。结果表明,社会隔离压力显著降低了母亲的耐力、整合和母亲行为的情绪性(自我平静)。同时,与对照组相比,SI应激组血液和海马皮质酮浓度显著升高,BDNF浓度显著降低。社会隔离大鼠海马GABAARα1 mRNA表达明显降低。这些发现表明,怀孕期间的社会隔离压力深刻地影响了大鼠的母性行为,包括耐力、整合和自我安慰。社会隔离组海马皮质酮、BDNF浓度和GABAARα1 mRNA表达的改变提示妊娠期应激反应调节和突触可塑性被破坏,以形成正常的母性行为。

Relationship between fluid intake, hydration status and cortisol dynamics in healthy, young adult males 健康年轻成年男性液体摄入量、水合状态和皮质醇动态的关系
IF 2.1 Q3 ENDOCRINOLOGY & METABOLISM Pub Date : 2025-02-01 Epub Date: 2025-01-02 DOI: 10.1016/j.cpnec.2024.100281

Background

Previous studies have identified links between fluid intake, hydration related hormones and cortisol measured at one timepoint but have not considered how hydration may influence cortisol dynamics throughout the day. This study assessed associations between hydration status (copeptin, urinary osmolality, urine volume) and habitual fluid intake with cortisol dynamics.

Methods

The day before (DB) a 6-h laboratory visit, 29 male participants (age, 23±4y; BMI, 25.5 ± 4.3 kg/m2; body fat, 17.3 ± 9.3 %) provided 24-h urine samples and a fasted blood sample for hydration status assessment, recorded their 24-h fluid intake for three days prior, and provided 10 saliva samples to assess cortisol dynamics from DB into the evening of the laboratory visit. Calculated indices of cortisol dynamics included: nocturnal cortisol rise (NCR – salivary cortisol rise from bed to awakening), peak salivary cortisol (peak SCORT – highest cortisol of all samples), cortisol awakening response (ΔCAR – difference between high morning sample and awakening sample), area under the curve with respect to ground (AUCG) and increase (AUCI), and diurnal cortisol slope (DCS – rate of change in cortisol from awakening to bed). The relationships between fluid intake or hydration status and cortisol dynamics were analyzed by separating participants into fluid intake tertile groups and by regressing cortisol dynamics on the continuous variables of total fluid intake (TFI) or hydration biomarkers.

Results

There were no between-group differences for ΔCAR (p = 0.89), AUCG (p = 0.57), AUCI (p = 0.48), peak SCORT (p = 0.14), NCR (p = 0.95), DCS (p = 0.22), or serum cortisol (p = 0.61). TFI was not associated with log (peak SCORT) (p = 0.49), ΔCAR (p = 0.61), AUCG (p = 0.76), or AUCI (p = 0.56). Copeptin was not associated with log (peak SCORT) (p = 0.99), ΔCAR (p = 0.22), AUCG (p = 0.69) or AUCI (p = 0.18). Urinary hydration markers were not associated with any measures of cortisol dynamics (p > 0.05). These null effects were consistent when controlling for physical activity, sleep, and body fat percentage.

Conclusion

In the absence of dehydrating stimuli, measures of fluid intake or hydration status may not be associated with cortisol dynamics in young healthy males.
背景:以前的研究已经确定了在一个时间点测量的液体摄入量、水合作用相关激素和皮质醇之间的联系,但没有考虑水合作用如何影响全天的皮质醇动态。本研究评估了水合状态(copeptin、尿渗透压、尿量)和习惯性液体摄入量与皮质醇动力学之间的关系。方法:前一天(DB) 6小时实验室访问,29名男性参与者(年龄,23±4y;BMI: 25.5±4.3 kg/m2;体脂(17.3±9.3%)提供24小时尿液样本和空腹血液样本用于水化状态评估,记录他们三天前24小时的液体摄入量,并提供10份唾液样本用于评估从DB到实验室访问晚上的皮质醇动态。皮质醇动态的计算指标包括:夜间皮质醇升高(NCR -从床上到床上的唾液皮质醇升高),唾液皮质醇峰值(SCORT峰值-所有样本中最高的皮质醇),皮质醇觉醒反应(ΔCAR -高早晨样本和觉醒样本之间的差异),相对于地面的曲线下面积(AUCG)和增加(AUCI),以及皮质醇斜率(DCS -皮质醇从醒来到床上的变化率)。通过将参与者分为液体摄入量各组,并通过总液体摄入量(TFI)或水合作用生物标志物的连续变量回归皮质醇动力学,分析了液体摄入量或水合作用状态与皮质醇动力学之间的关系。结果:ΔCAR (p = 0.89)、AUCG (p = 0.57)、AUCI (p = 0.48)、峰值SCORT (p = 0.14)、NCR (p = 0.95)、DCS (p = 0.22)、血清皮质醇(p = 0.61)组间差异均无统计学意义。TFI与log(峰值scot) (p = 0.49)、ΔCAR (p = 0.61)、AUCG (p = 0.76)或AUCI (p = 0.56)无关。Copeptin与log(峰值SCORT) (p = 0.99)、ΔCAR (p = 0.22)、AUCG (p = 0.69)或AUCI (p = 0.18)均无相关性。尿水化指标与皮质醇动态变化无相关性(p < 0.05)。在控制体力活动、睡眠和体脂百分比时,这些无效效应是一致的。结论:在缺乏脱水刺激的情况下,年轻健康男性的液体摄入量或水合状态可能与皮质醇动力学无关。

Blunted anticipatory stress responses on competition day in team sports athletes compared to individual sports athletes 与单项运动运动员相比,团队运动运动员在比赛日的预期压力反应较弱
IF 2.1 Q3 ENDOCRINOLOGY & METABOLISM Pub Date : 2024-11-01 Epub Date: 2024-08-05 DOI: 10.1016/j.cpnec.2024.100254

Knowledge of anticipatory stress responses before sports competitions is limited, thus this study examined the relationship between anticipatory stress in terms of salivary cortisol secretion in athletes on the morning of a competition and a comparison baseline day. Thirty-seven athletes collected three saliva samples over a 45-min period post-awakening (0, 30 and 45 min). Anticipatory stress was expressed as Area Under the Curve compared to ground (AUCg; total cortisol secretion). There was no significant difference in AUCg between baseline and competition days. However, a mixed two-factor ANOVA with day and sport type (individual vs. team) revealed a significant main effect of sport type (p < 0.01) and a significant interaction (p = 0.001). Individual athletes demonstrated increased AUCg on competition day compared to baseline, while team athletes demonstrated decreased AUCg on competition day compared to baseline. This blunting response was also observed when analysing the raw cortisol secretion levels upon awakening. These findings suggest there may be substantive differences in anticipatory stress between individual and team sport athletes.

人们对体育比赛前的预期压力反应了解有限,因此本研究从唾液皮质醇分泌的角度研究了运动员在比赛前一天早上的预期压力与对比基线日的预期压力之间的关系。37 名运动员在觉醒后的 45 分钟内(0、30 和 45 分钟)采集了三次唾液样本。预期压力用与地面相比的曲线下面积(AUCg;皮质醇总分泌量)表示。基线日和比赛日之间的 AUCg 没有明显差异。然而,一项包含比赛日和运动类型(个人与团队)的混合双因素方差分析显示,运动类型具有显著的主效应(p < 0.01)和显著的交互效应(p = 0.001)。与基线相比,个人运动员在比赛日的 AUCg 有所增加,而团队运动员在比赛日的 AUCg 则有所减少。在分析苏醒后皮质醇的原始分泌水平时,也观察到了这种钝化反应。这些研究结果表明,个人和团体项目运动员的预期压力可能存在实质性差异。

For decades it was believed that oxytocin was “just a female hormone.” This was a mistake. In the 21st century it has become clear that oxytocin arose from ancient roots, and acquired dozens of diverse functions throughout the mammalian body. This Special Issue of Comprehensive Psychoneuroendocrinology brings together a series of fifteen papers describing different facets and functions of oxytocin. Each author was invited to describe her perspectives on oxytocin, as well as to share experiences that led them to study this remarkable molecule. Many of these stories are highly personal and set in the context of what it means to be a female and to be an academic scientist. Oxytocin is not “just” a female hormone and these articles are not “just” routine descriptions of scientific facts. The readers are invited to join us in a celebration of the molecule that made us human.
几十年来,人们一直认为催产素 "只是一种女性荷尔蒙"。这是一个错误。在 21 世纪,人们已经清楚地认识到,催产素起源于远古,在哺乳动物体内具有数十种不同的功能。本期《综合精神神经内分泌学》特刊汇集了 15 篇系列论文,介绍催产素的不同方面和功能。每位作者都应邀阐述了自己对催产素的看法,并分享了促使他们研究这种非凡分子的经历。其中许多故事都非常个人化,并以女性和学术科学家的身份为背景。催产素 "不仅仅 "是一种女性荷尔蒙,这些文章也 "不仅仅 "是对科学事实的例行描述。我们邀请读者与我们一起庆祝这一造就人类的分子。
