Abstract
BACKGROUND The impact of a child's cancer diagnosis on subsequent maternal physical health is unclear. METHODS We identified all Ontario children diagnosed less than 18 years with cancer between 1992 and 2017. Linkage to administrative databases identified mothers who were matched to population controls. We identified physical health conditions, acute healthcare use, and preventive healthcare use through validated algorithms using healthcare data, and compared them between exposed (child with cancer) and unexposed mothers. Predictors of health outcomes were assessed among exposed mothers. RESULTS We identified 5311 exposed mothers and 19,516 matched unexposed mothers. For exposed mothers, median age at last follow-up was 48 years, (interquartile range: 42-53). Exposed mothers had an increased risk of cancer (hazard ratio [HR] 1.2, 95% confidence interval [95% CI]: 1.0-1.5, p = .03), but not of any other adverse physical outcomes or of increased acute healthcare use. Exposed mothers were more likely to receive influenza vaccinations (odds ratio 1.4, 95% CI: 1.3-1.5, p < .0001), and underwent cancer screening at the same rate as unexposed mothers. Among exposed mothers, bereavement was associated with a subsequent increased risk of cancer (HR 1.7, 95% CI: 1.2-2.5, p = .004) and death (HR 2.2, 95% CI: 1.2-4.1, p = .01). CONCLUSION Mothers of children with cancer are at increased risk of developing cancer, but not of other adverse physical health outcomes, and were equally or more likely to be adherent to preventive healthcare practices. Bereaved mothers were at increased risk of subsequent cancer and death. Interventions targeting specific subpopulations of mothers of children with cancer or focused on screening for specific cancers may be warranted.

"Mens Sana in Cute Sana"-A State of the Art of Mutual Etiopathogenetic Influence and Relevant Pathophysiological Pathways between Skin and Mental Disorders: An Integrated Approach to Contemporary Psychopathological Scenarios. Cells 2023; 12:1828. [PMID: 37508493 PMCID: PMC10377895 DOI: 10.3390/cells12141828] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Revised: 07/08/2023] [Accepted: 07/10/2023] [Indexed: 07/30/2023] Open
Abstract
The negative socioeconomic impact of mental health disorders and skin diseases has increased in part due to the conflict between Russia and Ukraine, which has been a fertile ground for the emergence of psychopathologies. It is firmly established that there is a direct thread of etiopathogenetic communication between skin diseases and neuropsychiatric disorders, and the literature has tried to reveal the pathophysiological mechanisms governing such bidirectionality. This paper discusses this complex network of molecular pathways that are targeted by conventional and biological pharmacological agents that appear to impact two pathological spheres that previously seemed to have little connection. This molecular discussion is supplemented with a literature review, from a clinical viewpoint, regarding skin-brain etiopathogenetic bidirectionality. We focus on post-traumatic stress disorder (PTSD), which can be considered for all intents and purposes a systemic inflammatory disease that also affects the skin. A brief overview is also provided on the diagnostic-therapeutic and follow-up potential of oxidative and inflammatory markers potentially involved in the pathophysiological mechanisms treated. The aim is to clarify how these mechanisms may be useful in defining different stress-coping strategies and thus individual phenotypes of stress sensitivity/resistance in order to promote personalized medicine in the field of psychodermatology.

Ubiquitination of ADRα1d/SerpinA1 complex stimulates hypoxia to induce gastric tumorigenesis with a combination of Helicobacter pylori and chronic stress through IL-1α. Gastric Cancer 2022; 25:726-740. [PMID: 35532840 DOI: 10.1007/s10120-022-01297-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Accepted: 04/01/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Helicobacter pylori (H. pylori) has been recognized as the class I carcinogen of gastric cancer and several studies have demonstrated that chronic stress may accelerate gastric cancer progression. However, the evidence is not sufficient. METHODS Here, we developed a mouse model that combined H. pylori infection with chronic stress. Gastric inflammation promotes gastric tumor development progression. To evaluate the number of pro-inflammatory cells through observing the numbers of activated macrophages and neutrophils in mice gastric tumors compared with untreated mice or only treated with one factor. ADRα1d /SerpinA1 expression and localization were assessed under stress conditions and H. pylori infection, and evaluated by analyzing IL-1α, CD8, platelet, and RBC status using α- or β- blockers against gastritis to prevent gastric cancer. RESULTS Further mechanism study showed that stress hormones increase the number of CD8+ lymphocytes by activating ADRβ2 receptors, leading to IL-1α secretion and tumorigenicity. Gastric carcinogenesis also involves gastric muscle contraction mediated through ADRα1d/Serpina1 interaction. Specifically, we showed that the ADRα1d/SerpinA1 complex increases glucose uptake and the development of hypoxia conditions. These responses promote platelet aggregation and muscle contraction. In turn, gastric cancer cells increase lactate production and promote gastric cell proliferation through Muc-13 and IL-1α stimulation. CONCLUSION H. pylori infection in combination with chronic stress can lead to gastric cancer, and the synergistic effects of cytokine production (i.e. IL-1α), T lymphocyte dysfunction contributes to gastric carcinogenesis which will offer treatment opportunities for stress-associated gastric cancer and provide new strategies for the prevention and treatment of gastric cancer in clinics.

Abstract
This paper aims to overview different types of stress, including DNA replication stress, oxidative stress, and psychological stress. Understanding the processes that constitute a cellular response to varied types of stress lets us find differences in how normal cells and cancer cells react to the appearance of a particular kind of stressor. The revealed dissimilarities are the key for targeting new molecules and signaling pathways in anticancer treatment. For this reason, molecular mechanisms that underlay DNA replication stress, oxidative stress, and psychological stress have been studied and briefly presented to indicate biochemical points that make stressors contribute to cancer development. What is more, the viewpoint in which cancer constitutes the outcome and the cause of stress has been taken into consideration. In a described way, this paper draws attention to the problem of cancer-related post-traumatic stress disorder and proposes a novel, multidimensional oncological approach, connecting anticancer treatment with psychiatric support.

Abstract
Nerve fibres are distributed throughout the body along with blood and lymphatic vessels. The intrinsic morphological characteristics of nerves and the general characteristics of secretions in the tumour microenvironment provide a solid theoretical basis for exploring how neuronal tissue can influence the progression of laryngeal cancer (LC). The central nervous system (CNS) and the peripheral nervous system (PNS) jointly control many aspects of cancer and have attracted widespread attention in the study of the progression, invasion and metastasis of tumour tissue banks. Stress activates the neuroendocrine response of the human hypothalamus-pituitary-adrenal (HPA) axis. LC cells induce nerve growth in the microenvironment by releasing neurotrophic factors (NTFs), and they can also stimulate neurite formation by secreting axons and axon guides. Conversely, nerve endings secrete factors that attract LC cells; this is known as perineural invasion (PNI) and promotes the progression of the associated cancer. In this paper, we summarize the systematic understanding of the role of neuroregulation in the LC tumour microenvironment (TME) and ways in which the TME accelerates nerve growth, which is closely related to the occurrence of LC.

Depression promotes lung carcinoma progression by regulating the tumor microenvironment in tumor-bearing models of C57BL/6J mice. Neurosci Lett 2021; 754:135851.

Abstract
Psychological stress is a common etiology among patients with lung cancer and serves as a potential indication of poor prognosis and advanced cancer clinical stage. Evidence indicates that depression is positively correlated with the evolvement of lung carcinoma. Nevertheless, the mechanisms underlying the effects of mental disorder on lung cancer have not been considerably and systemically explored. We hypothesized that mental disorder may affect the adjustment of the tumor microenvironment and immune cells. We used the chronic unpredictable mild stress (CUMS) procedure to induce depressed mice models and established tumor-bearing models of C57BL/6 J mice. Results revealed that the worsening of lung cancer was notably hastened in the CUMS + tumor group. Notably, the expression of PD-L1 in tumor issues increased in the tumor microenvironment, accompanied with a decline in the levels of CD8. On the basis of the date of tumor migration, our results indicated that MMPs and VEGF significantly increased after CUMS + tumor treatment. Thus, we demonstrated that modulation of the tumor microenvironment is pivotal for depression-promoted lung cancer migration.

Abstract
OBJECTIVE The primary objective of this review is to analyze and synthesize the best available evidence on the experiences and perceptions of psychological stress reported by pancreatic cancer patients at any time point from pre-diagnosis, diagnosis, treatment, post-treatment and/or follow-up care. INTRODUCTION A cancer diagnosis is known to be life-threatening, altering and limiting, and negatively affects an individual's activities of daily living. Despite developments in treatment options for pancreatic cancer patients, it represents the highest mortality and morbidity among cancers. Stress is a subjective phenomenon that negatively impacts an individual's psychological and emotional well-being, and interferes with the ability to cope with cancer symptoms and treatments. Identifying a patient's experience of stress could facilitate educational, spiritual and social resources to address his or her emotional and psychological needs. INCLUSION CRITERIA Qualitative studies that include individuals with pancreatic cancers, regardless of age, sex or ethnicity, will be considered for inclusion in this review. METHODS The databases to be searched include PubMed, CINAHL, Cochrane, Web of Science, Embase, Scopus, BioMed Central and PsycINFO. The search for gray literature will include Biosis, OpenGrey, Open Access Theses and Dissertations, and WorldCat. This systematic review will consider all published and unpublished studies with no date limitations. Selected studies will be assessed for methodological quality by two independent reviewers. Coding will be assigned to synthesize any differences in the experiences and perceptions of psychological stress at four time points. Where textual pooling is not possible, conclusions will be presented in narrative form.

Abstract
AbstractAlthough resilience varies depending on the specific type of adverse situation faced by the individual, to date resilience questionnaires do not consider its situational character. This study aims to develop and validate the Situated Subjective Resilience Questionnaire for Adults (SSRQA), which assesses resilience in five different adverse contexts. A total of 584 Spanish adults (including general population and clinical samples individuals) completed the SSRQA and other measures of resilience, optimism, and self-efficacy. Confirmatory factor analysis showed that the SSRQA structure fitted the situational model better (χ2/df = 1.90; CFI = .96; TLI = .95; RMSEA = .07) than the non-situational version (χ2/df = 4.99; CFI = .79; TLI = .76; RMSEA = .15). The SSRQA was shown to be reliable (α = .90) and to be significantly and positively correlated with other resilience measures (p < .001) and, to a lower degree, with optimism and self-efficacy (p < .001). Degree of exposure to each adverse situation was negatively correlated with resilience in the face of that situation (p < .05), supporting a vulnerability to stress model. The SSRQA has been demonstrated to be a reliable and valid situated measure for resilience towards different adverse contexts.

Abstract
BACKGROUND Fetal alcohol exposure (FAE) increases the susceptibility to carcinogen-induced mammary cancer progression in rodent models. FAE also decreases β-endorphin (β-EP) level and causes hyperstress response, which leads to inhibition of immune function against cancer. Previous studies have shown that injection of nanosphere-attached dibutyryl cyclic adenosine monophosphate (dbcAMP) into the third ventricle increases the number of β-EP neurons in the hypothalamus. In this study, we assessed the therapeutic potential of stress regulation using methods to increase hypothalamic levels of β-EP, a neuropeptide that inhibits stress axis activity, in treatment of carcinogen-induced mammary cancer in fetal alcohol exposed rats. METHODS Fetal alcohol exposed and control Sprague Dawley rats were given a dose of N-Nitroso-N-methylurea (MNU) at postnatal day 50 to induce mammary cancer growth. Upon detection of mammary tumors, the animals were either transplanted with β-EP neurons or injected with dbcAMP-delivering nanospheres into the hypothalamus to increase β-EP peptide production. Spleen cytokines were detected using reverse transcription polymerase chain reaction assays. Metastasis study was done by injecting mammary cancer cells MADB106 into jugular vein of β-EP-activated or control fetal alcohol exposed animals. RESULTS Both transplantation of β-EP neurons and injection of dbcAMP-delivering nanospheres inhibited MNU-induced mammary cancer growth in control rats, and reversed the effect of FAE on the susceptibility to mammary cancer. Similar to the previously reported immune-enhancing and stress-suppressive effects of β-EP transplantation, injection of dbcAMP-delivering nanospheres increased the levels of interferon-γ and granzyme B and decreased the levels of epinephrine and norepinephrine in fetal alcohol exposed rats. Mammary cancer cell metastasis study also showed that FAE increased incidence of lung tumor retention, while β-EP transplantation inhibited lung tumor growth in both normal and fetal alcohol exposed rats. CONCLUSIONS Our results suggest that increase of β-EP production in the hypothalamus may serve as a potential therapeutic strategy for treating the cancer growth in patients with chronic stress and compromised immune function, such as the patients with FAE.

Abstract
β-Endorphin (BEP)-producing neuron in the hypothalamus plays a key role in bringing the stress axis to a state of homeostasis and maintaining body immune defense system. Long-term delivery of BEP to obtain beneficial effect on chemoprevention is challenging, as the peptides rapidly develop tolerance. Using rats as animal models, we show here that transplantation of BEP neurons into the hypothalamus suppressed carcinogens- and hormone-induced cancers in various tissues and prevented growth and metastasis of established tumors via activation of innate immune functions. In addition, we show that intracerebroventricular administration of nanosphere-attached dibutyryl cyclic adenosine monophosphate (dbcAMP) increased the number of BEP neurons in the hypothalamus, reduced the stress response, enhanced the innate immune function, and prevented tumor cell growth, progression, and metastasis. BEP neuronal supplementation did not produce any deleterious effects on general health but was beneficial in suppressing age-induced alterations in physical activity, metabolic, and immune functions. We conclude that the neuroimmune system has significant control over cancer growth and progression, and that activation of the neuroimmune system via BEP neuronal supplementation/induction may have therapeutic value for cancer prevention and improvement of general health.

Abstract
We evaluated the pharmacological effects of Myelophil, a 30% ethanol extract of a mix of Astragali Radix and Salviae Radix, on oxidative stress-induced brain damage in mice caused by restraint stress. C57BL/6 male mice (eight weeks old) underwent daily oral administration of distilled water, Myelophil (25, 50, or 100mg/kg), or ascorbic acid (100mg/kg) 1h before induction of restraint stress, which involved 3h of immobilization per day for 21days. Nitric oxide levels, lipid peroxidation, activities of antioxidant enzymes (superoxide dismutase, catalase, and glutathione redox system enzymes), and concentrations of adrenaline, corticosterone, and interferon-γ, were measured in brain tissues and/or sera. Restraint stress-induced increases in nitric oxide levels (serum and brain tissues) and lipid peroxidation (brain tissues) were significantly attenuated by Myelophil treatment. Restraint stress moderately lowered total antioxidant capacity, catalase activity, glutathione content, and the activities of glutathione reductase, glutathione peroxidase, and glutathione S-transferase; all these responses were reversed by Myelophil. Myelophil significantly attenuated the elevated serum concentrations of adrenaline and corticosterone and restored serum and brain interferon-γ levels. Moreover, Myelophil normalized expression of the genes encoding monoamine oxidase A, catechol-O-methyltransferase, and phenylethanolamine N-methyltransferase, which was up-regulated by restraint stress in brain tissues. These results suggest that Myelophil has pharmacological properties protects brain tissues against stress-associated oxidative stress damage, perhaps in part through regulation of stress hormones.

Abstract
It has been reported that high levels of cholesterol and triglycerides are associated with increased risk of developing atherosclerosis and shorter life. In fact, vascular endothelial dysfunction occurs during the human aging process. Accumulation of lipids in vascular endothelium activates leukocytes to produce cytokines and chemokines which recruit macrophages. On the other hand, macrophages augment inflammatory response and secrete vascular endothelial growth factor, a key cytokine that mediates angiogenesis and inflammatory response. In addition, hyperlipidaemia is one of the main risk factors for aging, hypertension and diabetes. Here, we review the interrelationship between endothelial cells, high level of cholesterol, and aging.
