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.

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.

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。

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.

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.

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.

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.
