Project description:Sarcopenia is a multifaceted geriatric syndrome associated with the loss of muscle mass. We examined the relationship between low muscle mass and inflammatory cytokines in the context of aging. This study involved 299 participants (127 men and 172 women; mean age 63.3 ± 9.8 years) who underwent health checkups for body composition and inflammatory cytokine (TNF-alpha, IL-6, and MCP-1) levels. Muscle mass was determined using the skeletal muscle mass index. We divided the participants into the normal (N) and low muscle mass (L) groups and compared the levels of inflammatory cytokines in nonelderly (<65 years) and elderly (≥65 years) participants. Among the nonelderly subjects, C-reactive protein was significantly lower in the L group than in the N group (p < 0.05). However, there was no significant difference in the inflammatory cytokine levels between the groups. Among the elderly subjects, the TNF-alpha level was significantly lower in the L group than in the N group (p < 0.05), whereas there were no significant differences in the IL-6 and MCP-1 levels. Moreover, TNF-alpha was identified as a risk factor for the L group in the logistic regression analysis (Exp (B) 0.935, 95% CI: 0.876-0.997, p = 0.04). Although a low TNF-alpha level is a risk factor for low muscle mass, inflammatory cytokine levels are not necessarily elevated in elderly individuals with the loss of muscle mass.

Project description:ImportanceUveitis involves dysregulation of the ocular immune system. Stress has been shown to affect immune function, but it is unclear whether there is an association between stress and uveitis.ObjectiveTo determine whether having uveitis is associated with psychological stress.Design, setting, and participantsA cross-sectional, case-control study including a self-administered survey, medical records review, and diurnal salivary cortisol test was conducted at a university-based uveitis clinic and comprehensive eye clinic. Participants included 146 consecutive adults with noninfectious uveitis and age-matched controls with no eye disease. The study was conducted from December 1, 2017, to March 14, 2018.Main outcomes and measuresParticipants completed the self-administered, Cohen 10-item Perceived Stress Scale (PSS-10), a demographics questionnaire. Responses to each question were categorized on a 5-point Likert scale, with total scores ranging from 0 (no stress) to 40 (high stress). In addition, participants submitted 3 salivary cortisol samples. Those with uveitis were classified as having recently active or controlled disease through medical records review. The prespecified primary analysis was a linear regression of PSS-10 score and uveitis correcting for age, sex, educational level, employment, and median income. Secondary analyses included comparing PSS-10 scores in patients with recently active and controlled uveitis, determining predictors of stress, and comparing diurnal salivary cortisol between uveitis and control groups.ResultsOf 146 eligible patients, 17 declined participation and 9 consented but were excluded because they did not complete both questionnaires, resulting in 120 patients (80 uveitis; 40 controls) in the final analysis. Eighty participants (66.7%) were women, and 70 (58.3%) were white. Median age was 40 years (interquartile range, 29-59 years). Having uveitis was associated with a 4.3-point increase in PSS-10 score (95% CI, 1.8 to 6.9; P = .002). There was no significant difference in PSS-10 scores between patients with recently active and controlled uveitis (1.0 point greater for patients with active uveitis; 95% CI, -2.0 to 3.9; P = .52). Factors associated with increased PSS-10 score in patients with uveitis included female sex (coefficient, 4.0; 95% CI, 1.6 to 6.5; P = .002), current immunomodulatory therapy (coefficient, 2.5; 95% CI, -0.3 to 5.2; P = .08), history of depression (coefficient, 3.8; 95% CI, 0.8 to 6.8; P = .02), and having posterior or panuveitis (coefficient, 2.6; 95% CI, 0.8 to 4.4; P = .006). Of the 70 participants (58.3%) who had testable samples for cortisol analysis, diurnal salivary cortisol levels did not significantly differ between uveitis and nonuveitis groups.Conclusions and relevanceThese findings suggest that patients with uveitis have higher levels of psychological stress compared with controls, yet no significant difference was identified in the stress of patients with active vs controlled uveitis. Consequently, comprehensive treatment for noninfectious uveitis may be able to address the psychological results of this disease.

Project description:BACKGROUND:Prenatal psychological stress during pregnancy has been associated with adverse reproductive outcomes. A growing animal literature supports an association between psychological stress and oxidative stress. We assessed this relationship in pregnant women, hypothesising that psychological stress is associated with higher concentrations of oxidative stress biomarkers during pregnancy. METHODS:Psychosocial status and stressful life events (SLE) were self-reported. 8-iso-prostaglandin F2α (8-iso-PGF2α ) was measured as a biomarker of oxidative stress in urine samples at median 32 weeks' gestation. We examined SLEs individually (ever vs never) and in summary (any vs none) and psychosocial status as measured by individual subscales and in summary (poor vs good). Linear models estimated associations between these parameters and urinary 8-iso-PGF2α concentrations after adjusting for covariates. RESULTS:The geometric mean of 8-iso-PGF2α was significantly higher among pregnant women who were non-White, smokers, had less than a college education, higher pre-pregnancy BMI and were unmarried. Having ever had a death in the family (n = 39) during pregnancy was associated with a 22.9% increase in 8-iso-PGF2α in unadjusted models (95% confidence interval [CI] 1.50, 48.8). Poor psychosocial status was associated with a 13.1% (95% CI 2.43, 25.0) greater mean 8-iso-PGF2α in unadjusted analyses. Associations were attenuated, but remained suggestive, after covariate adjustment. CONCLUSIONS:These data suggest that 8-iso-PGF2α is elevated in pregnant women with who are at a sociodemographic disadvantage and who have higher psychological stress in pregnancy. Previous studies have observed that 8-iso-PGF2α levels are associated with adverse birth outcomes, oxidative stress could be a mediator in these relationships.

Project description:BACKGROUND:Mechanisms underlying oral immunotherapy (OIT) are unclear and the effects on immune cells at varying maintenance doses are unknown. OBJECTIVE:We aimed to determine the immunologic changes caused by peanut OIT in preschool aged children and determine the effect on these immune responses in groups ingesting low or high-dose peanut OIT (300 mg or 3000 mg, respectively) as maintenance therapy. METHODS:Blood was drawn at several time-points throughout the OIT protocol and PBMCs isolated and cultured with peanut antigens. Secreted cytokines were quantified via multiplex assay, whereas Treg and peanut-responsive CD4 T cells were studied with flow cytometry. Basophil activation assays were also conducted. RESULTS:Th2-, Th1-, Th9- and Tr1-type cytokines decreased over the course of OIT in groups on high- and low-dose OIT. There were no significant differences detected in cytokine changes between the high- and low-dose groups. The initial increase in both the number of peanut-responsive CD4 T cells and the number of Tregs was transient and no significant differences were found between groups. Basophil activation following peanut stimulation was decreased over the course of OIT and associated with increased peanut-IgG4/IgE ratios. No differences were found between high- and low-dose groups in basophil activation at the time of desensitization or sustained unresponsiveness oral food challenges. CONCLUSIONS AND CLINICAL RELEVANCE:Peanut OIT leads to decreases in pro-allergic cytokines, including IL-5, IL-13, and IL-9 and decreased basophil activation. No differences in T cell or basophil responses were found between subjects on low or high-dose maintenance OIT, which has implications for clinical dosing strategies.

Project description:BackgroundPoor maternal mental health is a major risk factor for adverse offspring health outcomes, including overweight/obesity status. Maternal mental distress is highly prevalent and associated with parenting practices influencing child weight. To date, there is little information documented in Ethiopia on maternal mental distress and children with overweight/obesity status. This study examined the association between maternal mental distress and children with overweight/obesity among mother-child dyads in Addis Ababa, Ethiopia.MethodsAn observational population-based cross-sectional study was conducted among mother-child dyads in representative samples in Addis Ababa, Ethiopia. Maternal mental distress was measured using the Self-Reporting Questionnaire (SRQ)-20. Child/adolescent overweight/obesity was defined as more than 1 SD above the median World Health Organization (WHO) growth reference. Multivariate logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).ResultsThe prevalence of maternal mental distress and children with overweight/obesity was estimated to be 10.1% and 28.8%, respectively. After adjusting for confounders, including maternal education, maternal occupation, average monthly household income, maternal body mass index (BMI) and the number of household members/family size, maternal psychological distress was not associated with offspring overweight/obesity status (adjusted OR [aOR] = 0.54; 95% CI: 0.25, 1.14).ConclusionsThere is no evidence of an association between maternal psychological distress and children with overweight/obesity. This lack of association might be attributable to our cross-sectional study design. Future epidemiologic studies, particularly those using prospectively collected data, are warranted to examine better the effects of maternal psychological distress on offspring body weight.

Project description:This systematic review aims to investigate the association between psychological stress and periodontitis through analysis of cortisol levels and periodontal clinical parameters. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guide and based on PECO (Participants, Exposure, Comparators, Outcomes) question and registered at PROSPERO under the code CRD42017076670. As eligibility criteria, observational studies performed in adult humans presenting periodontitis (P), which evaluated patients exposed (E) and nonexposed to psychological stress (C) and to verify the association between this type of stress and periodontitis (O) were included. The searches were performed until March 2018. The following databases were used: PubMed, Scopus, Web of Science, The Cochrane Library, LILACS, OpenGrey, and Google Scholar. After searches, the duplicate results were removed. The remaining citations were selected according to eligibility criteria in two phases. In the first phase, the title/abstract was evaluated. In the second phase, the articles were chosen previously were assessed by full text. After selection, the studies were submitted to data extraction and risk of bias evaluation by Fowkes and Fulton. A total of 1,386 citations were retrieved. After duplicates removal and selection process, three articles were selected by full text. Among them, two articles reported a positive association between psychological stress and periodontitis. All articles were classified as low risk of bias. Even though two articles highlighted an association between psychological stress and the presence of a possible modulatory pattern of cortisol levels in clinical parameters of periodontitis, more studies are necessary to elucidate this question.

Project description:BackgroundAnti-citrullinated peptide antibodies (ACPA) and inflammatory cytokines play important roles in the development of rheumatoid arthritis (RA). T cell immunoglobulin and mucin-domain containing-3 (TIM-3) is an immune-checkpoint molecule involved in inhibitory signaling. Galectin-9 (Gal-9) mediated ligation of TIM-3 induces the amelioration of autoimmune diseases. TIM-3 is expressed in synovial osteoclasts and involved in the rheumatoid bone destruction. The aim of this study was to investigate the relationships between inflammatory cytokines and immune-checkpoint molecules in RA patients.MethodsSerum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), soluble TIM-3 (sTIM-3) and Gal-9 were determined by ELISA. Patients were stratified into two groups based on ACPA titers: low-medium ACPA (ACPA <200 U/mL) and high ACPA (ACPA ≥200 U/mL). Serum levels of cytokines or immune-checkpoint molecules were evaluated between RA patients with low-medium ACPA titers and high ACPA titers.ResultsElevated serum levels of inflammatory cytokines were correlated with DAS28-ESR in RA patients. Although serum levels of sTIM-3 were elevated in RA patients, significant correlations between sTIM-3 and cytokines (IL-6 or TNF-α) were observed exclusively in RA patients with low-medium ACPA titers (<200 U/mL). Serum levels of IL-6 and TNF-α levels were significantly correlated with elevated Gal-9 levels regardless of ACPA status. A significant correlation between IL-6 and Gal-9 was observed in RA patients without advanced joint damage. Conversely, a significant correlation between TNF-α and Gal-9 was observed in RA patients with advanced joint damage.ConclusionsOur data indicated that there are positive correlations between circulating inflammatory cytokines and checkpoint molecules in RA patients and these interactions can be modulated by ACPA status or joint damage stage.

Project description:Birthweight is an important predictor of newborn health and has been linked to maternal psychological stress during pregnancy. However, it is unclear whether prenatal stress affects birthweight similarly for both male and female infants. We used a well-established pregnancy cohort to investigate the impact of high maternal psychological stress during pregnancy on birthweight as a function of infant sex. Overall, 5702 mother-newborn pairs were analysed. Of these, 198 mothers reported high levels of stress using the Psychological Stress Measure (nine-items version; PSM-9). Maternal psychological stress was assessed between the 24th and 28th week of gestation and analyses were performed jointly and independently as a function of neonatal sex (separate analyses for male and female infants). Newborns exposed to high maternal psychological stress during pregnancy (a score above 26 measured using the PSM-9 questionnaire, corresponding to >97.5th percentile) were compared to newborns of mothers who reported lower stress. ANCOVAs revealed that high levels of maternal stress during pregnancy were linked to infant birthweight as a function of infant sex. Male infants of mothers who reported high levels of stress had a greater birthweight whereas female infants had a lower birthweight under the same conditions, in comparison to mothers who did not report greater levels of stress. Although the effect size is small, these results underline the possibility that male and female fetuses may use different strategies when adapting to maternal adversity and highlight the need to consider infant sex as a moderator of the association between maternal psychological stress during pregnancy and infant birthweight.

Project description:Background Experimental studies suggest that prenatal stress affects reproductive function in female offspring, but human evidence is sparse and inconsistent. In this present study, we aim to investigate whether maternal psychological stress, quantified as stressful life events during pregnancy, affect reproductive function in the female offspring. Method In a large population-based pregnancy cohort study (The Raine Study) continuously followed from prenatal life through to adolescence we examined the association between the number of maternal stressful life events in both early and late gestation and subsequent ovarian and uterine function in 228 female adolescent offspring. Mothers prospectively reported stressful life events during pregnancy at 18 and 34 weeks using a standardized 10-point questionnaire. Female offspring (n = 228) age 14–16 years underwent gynecological examination including transabdominal abdominal ultrasound (TAUS) to measure uterine volume and ovarian AFC. Plasma samples on day 2–6 of the spontaneous menstrual cycle measured circulating AMH and inhibin B. Multivariate linear regression analysis was used to examine the associations between maternal stressful life events and reproductive function in female offspring. Adolescents taking hormonal contraception were excluded. Results Most adolescents (145/228, 64%) were exposed to at least one stressful life event in early gestation and around half (125/228, 55%) were exposed to at least one in later gestation. Exposure to one or more maternal stressful life events in late gestation was associated with a greater uterine volume (β = 0.13, 95% CI 0.04; 0.23) and higher ovarian AFC (β = 0.19, 95% CI 0.02; 0.35) at age 14–16 years. No associations between maternal stressful events in late gestation and reproductive function were identified. No associations between stressful life events in early or late gestation and circulating AMH or Inhibin B were observed. Conclusion Maternal psychological stress in late, but not early gestation was associated with a significantly greater uterine volume and ovarian antral follicle count (AFC) in adolescent offspring but did not affect ovarian production of antimullerian hormone (AMH) or Inhibin B. These findings suggest that female reproductive function is influenced by prenatal exposure to stress. Highlights • Animal studies suggest reproductive function is influenced by maternal stress.• Human evidence is sparse and inconsistent.• We used a population-based pregnancy cohort of 228 mother female offspring.• Exposure to maternal psychological stress in late gestation affects uterine volume and ovarian AFC.

Project description:ObjectivesPrevious research has suggested connections between specific inflammatory cytokines and nasal conditions, including Allergic Rhinitis (AR), Chronic Rhinosinusitis (CRS), and Nasal Polyps (NP). However, a lack of robust research establishing the causal underpinnings of them. This Mendelian Randomization (MR) study aims to evaluate the causal relationships between 41 inflammatory cytokines and the incidence of AR, CRS and NP.MethodsThis study employed a two-sample MR design, harnessing genetic variations derived from publicly accessible genome-wide association studies (GWAS) datasets. AR data was sourced from a GWAS with 25,486 cases and 87,097 controls (identifier: ukb-b-7178). CRS data originated from a GWAS encompassing 1,179 cases and 360,015 controls (identifier: ukb-d-J32). NP data was extracted from a GWAS involving 1,637 cases and 335,562 controls (identifier: ukb-a-541). The data for 41 inflammatory cytokines were obtained from an independent GWAS encompassing 8,293 participants. Inverse variance weighted (IVW), MR Egger regression and Weighted median were used to evaluate the causalities of exposures and outcomes. A range of sensitivity analyses were implemented to assess the robustness of the results.ResultsThe results revealed significant associations between elevated circulating levels of MIP-1α (odds ratio, OR: 1.01798, 95% confidence interval, CI: 1.00217-1.03404, p = 0.02570) and TNF-α (OR: 1.01478, 95% CI: 1.00225-1.02746, p = 0.02067) with an augmented risk of AR in the IVW approach. Heightened levels of circulating IL-2 exhibited a positive correlation with an increased susceptibility to NP in the IVW approach (OR: 1.00129, 95% CI: 1.00017-1.00242, p = 0.02434), whereas elevated levels of circulating PDGF-BB demonstrated a decreased risk of NP (OR: 0.99920, 95% CI: 0.99841-0.99999, p = 0.047610). The MR analysis between levels of 41 inflammatory cytokines and the incidence of CRS yielded no positive outcomes.ConclusionThis investigation proposes a potential causal association between elevated levels of MIP-1α and TNF-α with an elevated risk of AR, as well as an increased risk of NP linked to elevated IL-2 levels. Furthermore, there appears to be a potential association between increased levels of circulating PDGF-BB and a reduced risk of NP.
