    ACE2 Deficiency Worsens Epicardial Adipose Tissue Inflammation and Cardiac Dysfunction in Response to Diet-Induced Obesity
    (American Diabetes Association, 2016-01) Patel, Vaibhav B.; Mori, Jun; McLean, Brent A.; Basu, Ratnadeep; Das, Subhash K.; Ramprasath, Tharmarajan; Parajuli, Nirmal; Penninger, Josef M.; Grant, Maria B.; Lopaschuk, Gary D.; Oudit, Gavin Y.; Department of Ophthalmology, IU School of Medicine
    Obesity is increasing in prevalence and is strongly associated with metabolic and cardiovascular disorders. The renin-angiotensin system (RAS) has emerged as a key pathogenic mechanism for these disorders; angiotensin (Ang)-converting enzyme 2 (ACE2) negatively regulates RAS by metabolizing Ang II into Ang 1-7. We studied the role of ACE2 in obesity-mediated cardiac dysfunction. ACE2 null (ACE2KO) and wild-type (WT) mice were fed a high-fat diet (HFD) or a control diet and studied at 6 months of age. Loss of ACE2 resulted in decreased weight gain but increased glucose intolerance, epicardial adipose tissue (EAT) inflammation, and polarization of macrophages into a proinflammatory phenotype in response to HFD. Similarly, human EAT in patients with obesity and heart failure displayed a proinflammatory macrophage phenotype. Exacerbated EAT inflammation in ACE2KO-HFD mice was associated with decreased myocardial adiponectin, decreased phosphorylation of AMPK, increased cardiac steatosis and lipotoxicity, and myocardial insulin resistance, which worsened heart function. Ang 1-7 (24 µg/kg/h) administered to ACE2KO-HFD mice resulted in ameliorated EAT inflammation and reduced cardiac steatosis and lipotoxicity, resulting in normalization of heart failure. In conclusion, ACE2 plays a novel role in heart disease associated with obesity wherein ACE2 negatively regulates obesity-induced EAT inflammation and cardiac insulin resistance.

    Association of Chlamydia trachomatis burden with the vaginal microbiota, bacterial vaginosis, and metronidazole treatment
    (Frontiers Media, 2023-12-12) Ardizzone, Caleb M.; Taylor, Christopher M.; Toh, Evelyn; Lillis, Rebecca A.; Elnaggar, Jacob H.; Lammons, John W.; Dehon Mott, Patricia; Duffy, Emily L.; Shen, Li; Quayle, Alison J.; Microbiology and Immunology, School of Medicine
    Bacterial vaginosis (BV), a dysbiosis of the vaginal microbiota, is a common coinfection with Chlamydia trachomatis (Ct), and BV-associated bacteria (BVAB) and their products have been implicated in aiding Ct evade natural immunity. Here, we determined if a non-optimal vaginal microbiota was associated with a higher genital Ct burden and if metronidazole, a standard treatment for BV, would reduce Ct burden or aid in natural clearance of Ct infection. Cervicovaginal samples were collected from women at enrollment and, if testing positive for Ct infection, at a follow-up visit approximately one week later. Cervical Ct burden was assessed by inclusion forming units (IFU) and Ct genome copy number (GCN), and 16S rRNA gene sequencing was used to determine the composition of the vaginal microbiota. We observed a six-log spectrum of IFU and an eight-log spectrum of GCN in our study participants at their enrollment visit, but BV, as indicated by Amsel’s criteria, Nugent scoring, or VALENCIA community state typing, did not predict infectious and total Ct burden, although IFU : GCN increased with Amsel and Nugent scores and in BV-like community state types. Ct burden was, however, associated with the abundance of bacterial species in the vaginal microbiota, negatively with Lactobacillus crispatus and positively with Prevotella bivia. Women diagnosed with BV were treated with metronidazole, and Ct burden was significantly reduced in those who resolved BV with treatment. A subset of women naturally cleared Ct infection in the interim, typified by low Ct burden at enrollment and resolution of BV. Abundance of many BVAB decreased, and Lactobacillus increased, in response to metronidazole treatment, but no changes in abundances of specific vaginal bacteria were unique to women who spontaneously cleared Ct infection.

    Associations between Benign Cutaneous Nevi and Risk of Type 2 Diabetes Mellitus in Men and Women: Results from Two Prospective Cohort Studies
    (Office of the Vice Chancellor for Research, 2015-04-17) Dai, Hongji; Sun, Qi; Zhang, Xi; Manson, JoAnn E.; Hu, Frank B.; Song, Yiqing
    ABSTRACT Objective: Previous studies suggest that the number of cutaneous nevi and type 2 diabetes mellitus (T2DM) are both associated with endogenous sex hormone levels. However, no prospective studies have specifically examined the relationship between the number of benign cutaneous nevi and T2DM. Research Design and Methods: We prospectively examined the associations between the number of nevi and risk of T2DM among 23,748 men (1986-2010) from the Health Professionals Follow-up Study (HPFS) and 67,050 women (1989-2010) from the Nurses' Health Study (NHS). Information on the numbers of melanocytic nevi on arms and the incidence of T2DM was collected by validated questionnaires. Results: During 1,831,118 person-years of follow-up, we documented 8748 incident cases of T2DM. After adjustment for age, BMI, and other diabetes risk factors, the number of nevi was significantly associated with increased risk of T2DM. Multivariable-adjusted HRs (95% CIs) for <1, 1-5, 6-14, and ≥15 nevi were 1.00 (reference), 1.02 (0.92, 1.14), 1.10 (0.87, 1.38), and 1.70 (1.22, 2.36), respectively, for men (P trend = 0.03) and 1.00 (reference), 1.15 (1.09, 1.21), 1.25 (1.11, 1.40), and 1.70 (1.38, 2.09), respectively, for women (P trend = 0.019). This positive association remained consistent across subgroups of participants. Conclusions: Mole count may represent a novel marker for development of T2DM in men and women, indicating a unique nevus development-related mechanism, possibly due to altered levels or functions of endogenous steroid sex hormones, in the pathogenesis of T2DM. Further studies are warranted to clarify the relationship of nevogenesis and T2DM and underlying mechanisms.

    Associations of Metabolic syndrome and C-reactive protein with Mortality from total cancer, obesity-linked cancers and Breast Cancer among Women in NHANES III
    (Wiley, 2018-08) Gathirua-Mwangi, Wambui G.; Song, Yiqing; Monahan, Patrick; Champion, Victoria L.; Zollinger, Terrell; Biostatistics, School of Public Health
    Although metabolic syndrome (MetS) is a prognostic factor for cancer occurrence, the association of MetS and cancer mortality remains unclear. The purpose of this study was to evaluate whether MetS, components of MetS and C-reactive protein (CRP) are associated with cancer mortality in women. A total of 400 cancer deaths, with 140 deaths from obesity-linked-cancers (OLCas), [breast (BCa), colorectal, pancreatic and endometrial], linked through the National Death Index, were identified from 10,104 eligible subjects aged ≥18 years. Cox proportional hazards regression was used to estimate multivariable-adjusted hazard ratios (HR) for cancer mortality. MetS was associated with increased deaths for total cancer [HR = 1.33, 95% confidence interval (CI) 1.04-1.70] and BCa [HR = 2.1, 95% CI, 1.09-4.11]. The risk of total cancer [HR = 1.7, 95% CI, 1.12-2.68], OLCas [HR = 2.1, 95% CI, 1.00-4.37] and BCa [HR = 3.8, 95% CI, 1.34-10.91] mortality was highest for women with all MetS components abnormal, compared to those without MetS. Linear associations of blood-pressure [HR = 2.5, 1.02-6.12, Quartile (Q) 4 vs Q1, p trend = 0.004] and blood-glucose [HR = 2.2, 1.04-4.60, Q4 vs. Q1, p trend = 0.04] with total-OLCas mortality were observed. A threefold increased risk of BCa mortality was observed for women with enlarged waist circumference, ≥100.9 cm, [HR = 3.5, 1.14-10.51, p trend = 0.008] and in those with increased blood glucose, ≥101 mg/dL, [HR = 3.2, 1.11-9.20, p trend = 0.03] compared to those in Q1. None of the components of MetS were associated with total-cancer mortality. CRP was not associated with cancer mortality. In conclusion, MetS is associated with total-cancer and breast-cancer mortality, with waist circumference, blood pressure and blood glucose as independent predictors of OLCas and BCa mortality.

    AVE/EVA: Un recorrido por la historia cultural de las mujeres en España
    (2021) Mallorquí-Ruscalleda, Enric
    Within the system of patriarchy that has presided over the West throughout history, women –and femininity– have been represented in a contrasting, antagonistic and irreconcilable way based on what has materialized with the AVE/EVA palindrome. Given the centrality of this theme and its renewed relevance within the political and social debates around gender, this conference will draw a historical overview of the different and conflicting representations of women throughout the history of Spain from the analysis of literary texts and other cultural artifacts that will help us better understand the different representations of women that have served as the basis for building the different constructions of gender identity throughout the centuries.

    Barriers, Facilitators, and Suggestive HIV Interventions for Women: Preliminary Data from a Secondary Analysis
    (Office of the Vice Chancellor for Research, 2013-04-05) Schmitt, Herman C.; Burrage, Joe
    The Centers for Disease Control and Prevention report that women account for almost ten thousand of those newly diagnosed with HIV annually. Within this group, Latina, non-Latina white and non-Latina black women are particularly affected. The purpose of this secondary analysis was to analyze existing de-identified data for barriers and facilitators for HIV testing and willingness to participate in a vaccine if available. The data were 30 de-identified transcripts of one hour interviews obtained from three groups of women (10 Latinas, 10 non-Latina white, and 10 non- Latina black) during the initial phase of a parent study, “HIV Testing and Women’s Attitudes on HIV Vaccine Trials”: G. Zimet, PI. A semi-structured interview guide had been used to guide the interviews. This sub analysis was conducted with removal of ethnic classification to reduce bias during qualitative review. Three predominant categories of fear, time, and cost emerged from all interviews regardless of ethnicity. Less prominent categories of gender, education, trust, motherhood, discrimination, loss of integrity, invincibility, safety, age, testing accuracy, confidentiality, indifference, pride, lifestyle, divine justice, and stress varied among the three groups. These categories will provide the basis for further analysis to determine subthemes and themes, and if there are themes unique to any of the three groups.

    Blood Levels of Endocannabinoids, Oxylipins, and Metabolites Are Altered in Hemodialysis Patients
    (MDPI, 2022-08-29) Watkins, Bruce A.; Friedman, Allon N.; Kim, Jeffrey; Borkowski, Kamil; Kaiser, Shaun; Fiehn, Oliver; Newman, John W.; Medicine, School of Medicine
    Hemodialysis patients (HDPs) have higher blood pressure, higher levels of inflammation, a higher risk of cardiovascular disease, and unusually low plasma n-3 polyunsaturated fatty acid (PUFA) levels compared to healthy subjects. The objective of our investigation was to examine the levels of endocannabinoids (eCBs) and oxylipins (OxLs) in female HDPs compared to healthy matched female controls, with the underlying hypothesis that differences in specific PUFA levels in hemodialysis patients would result in changes in eCBs and OxLs. Plasma phospholipid fatty acids were analyzed by gas chromatography. Plasma was extracted and analyzed using ultra-performance liquid chromatography followed by electrospray ionization and tandem MS for eCBs and OxLs. The global untargeted metabolite profiling of plasma was performed by GCTOF MS. Compared to the controls, HDPs showed lower levels of plasma EPA and the associated OxL metabolites 5- and 12-HEPE, 14,15-DiHETE, as well as DHA derived 19(20)-EpDPE. Meanwhile, no changes in arachidonylethanolamide or 2-arachidonylglycerol in the open circulation were detected. Higher levels of multiple N-acylethanolamides, monoacylglycerols, biomarkers of progressive kidney disease, the nitric oxide metabolism-linked citrulline, and the uremic toxins kynurenine and creatine were observed in HDP. These metabolic differences in cCBs and OxLs help explain the severe inflammatory and cardiovascular disease manifested by HDPs, and they should be explored in future studies.
