Variations in Breast Cancer Screening and Health Behaviors by Age and Race Among Attendees of Women’s Health Clinics

ObjectiveBreast cancer mortality has declined, yet disease outcomes have not improved equally across populations. Disparities may initiate early in the continuum of care, in health behavior patterns, and screening practices. We examined variations in mammography, exercise, fruit and vegetable intake, alcohol consumption, and body mass index (BMI, kg/ m²) by age and race in a diverse sample of clinic patients.MethodsWe analyzed survey data collected at baseline from 855 women (>40 years old) in women’s health clinics, who were recruited for a risk-tailored intervention. Screening practices, health behaviors, and demographics were surveyed. Statistical analyses were performed using bivariate difference tests and multiple logistic regression.ResultsOverall, 47% of the women were African American, with a mean age of 50 years. Older women were twice as likely as younger women to have had mammography within the previous year and significantly more likely than women 10 years younger to exercise at least 3 times weekly. African American women were significantly less likely than white women to exercise at least 3 times weekly, eat more than 2 servings daily of fruit and vegetables, or report a BMI of less than < 25 kg/m². Mammography rates were comparable by race except among lesser-educated African American women, who showed higher rates versus comparable white women.ConclusionsNew intervention models that link health behavior information with screening messages in clinical settings may be important in reducing breast cancer risk and mortality.     

Pre–Post Tornado Effects on Aggressive Children’s Psychological and Behavioral Adjustment Through One-Year Postdisaster

Using a risk-resilience framework, this study examined how varying levels of exposure to a natural disaster (EF-4 tornado) and children’s characteristics (sex; anxiety) influenced the behavioral and psychological adjustment of children who shared a common risk factor predisaster (elevated aggression) prior to exposure through 1-year postdisaster. Participants included 360 children in Grades 4–6 (65% male; 78% African American) and their parents from predominantly low-income households who were already participating in a longitudinal study of indicated prevention effects for externalizing outcomes when the tornado occurred in 2011. Fourth-grade children who were screened for overt aggressive behavior were recruited in 3 annual cohorts (120 per year, beginning in 2009). Parent-rated aggression and internalizing problems were assessed prior to the tornado (Wave 1), within a half-year after the tornado (Wave 2), and at a 1-year follow-up (Wave 3). Children and parents rated their exposure to aspects of tornado-related traumatic experiences at Wave 3. Children displayed less reduction on aggression and internalizing problems if the children had experienced distress after the tornado or fears for their life, in combination with their pre-tornado level of anxiety. Higher levels of children’s and parents’ exposure to the tornado interacted with children’s lower baseline child anxiety to predict less reduction in aggression and internalizing problems 1 year after the tornado. Higher levels of disaster exposure negatively affected at-risk children’s level of improvement in aggression and internalizing problems, when life threat (parent- and child-reported) and child-reported distress after the tornado were moderated by baseline anxiety.     

Aging and Neurocognitive Functioning in HIV-Infected Women: a Review of the Literature Involving the Women’s Interagency HIV Study

HIV-infected women may be particularly vulnerable to certain types of neurocognitive impairments which may be exacerbated by aging and other predictors. Within the context of cognitive reserve, this article examines issues surrounding women as they age with HIV. For this, a review of 12 recent studies (2013–2016) using data from the Women’s Interagency HIV Study (WIHS), the largest cohort study comparing HIV-infected and demographically matched uninfected women, is presented that specifically examines neurocognition. In general, HIV-infected women are more vulnerable to developing neurocognitive impairments than uninfected women; other factors that may contribute to these neurocognitive impairments include recent illicit drug use, reading level (educational quality/cognitive reserve), stress, PTSD, insulin resistance, liver fibrosis, and age. Surprisingly, when examined in some analyses, age × HIV interactions were not observed to impact neurocognitive performance, findings largely consistent in the literature; however, longitudinal analyses of these data have yet to be performed which may yield future insights of how cognitive reserve may be compromised over time. Yet, with insulin resistance, liver fibrosis, stress, and other known predictors of poorer neurocognition also occurring more with advanced age, in time, the synergistic effect of age and HIV may be more robust and observable as this population ages.

Body image satisfaction and depression in midlife women: the Study of Women’s Health Across the Nation (SWAN)

With aging, women’s bodies undergo changes that can affect body image perception, yet little is known about body image in midlife. The purpose of this study was to examine associations between body image and depressive symptoms in Caucasian and African–American midlife women from the Study of Women’s Health Across the Nation (SWAN) Chicago site. Body image was measured using the Stunkard Adult Female Figure Rating Scale, and a clinically significant level of depressive symptoms was defined as Center for Epidemiologic Studies Depression Scale (CES-D) score of ≥16 (N?=?405; N?=?63 (15.6 %) with clinically significant levels of depressive symptoms). Differences between perceived actual, perceived ideal, and actual body size and responses to questions concerning weight satisfaction and attractiveness were examined using logistic regression for associations with a CES-D score of ≥16. Women with body image dissatisfaction (odds ratio (OR)?=?1.91; p?=?0.04) or who perceived themselves as “unattractive” (OR?=?7.74; p?<?0.01) had higher odds of CES-D of ≥16. We found no significant difference by race. Our results were not confounded by BMI. These results suggest that midlife women with poor body image may be more likely to have clinically significant levels of depressive symptoms. Larger prospective studies are needed to better understand this association.     

Experiences of Possession and Paranormal Phenomena Among Women in the General Population: Are They Related to Traumatic Stress and Dissociation?

This study sought to determine the prevalence of experiences of possession and paranormal phenomena (PNP) in the general population and their possible relations to each other and to traumatic stress and dissociation. The study was conducted on a representative female sample recruited from a town in central eastern Turkey. The Dissociative Disorders Interview Schedule, the posttraumatic stress disorder (PTSD) and borderline personality disorder sections of the Structured Clinical Interviews for DSM–IV Axis-I and Personality Disorders, and the Childhood Abuse and Neglect Questionnaire were administered to 628 women. Of these, 127 (20.2%) women reported at least 1 type of PNP and 13 (2.1%) women reported possession. Women with a dissociative disorder reported all types of possession and PNP (except telepathy) more frequently than those without. Whereas women with a trauma history in childhood and adulthood or PTSD reported possession more frequently than those without, PNP were associated with childhood trauma only. Factor analysis yielded 4 dimensions: possession by and/or contact with nonhuman entities, extrasensory communications, possession by a human entity, and precognition. These factors correlated with number of secondary features of dissociative identity disorder and Schneiderian symptoms. Latent class analysis identified 3 groups. The most traumatized group, with predominantly dissociative and trauma-related disorders, had the highest scores on all factors. Notwithstanding their presence in healthy individuals, possession and PNP were associated with trauma and dissociation in a subgroup of affected participants. Both types of experience seem to be normal human capacities of experiencing that may be involved in response to traumatic stress. Given the small numbers, this study should be considered preliminary.     

Unmet Needs in Systemic Sclerosis Understanding and Treatment: the Knowledge Gaps from a Scientist’s,Clinician’s,and Patient’s Perspective

Systemic sclerosis (SSc) is a highly heterogeneous disease caused by a complex molecular circuitry. For decades, clinical and molecular research focused on understanding the primary process of fibrosis. More recently, the inflammatory, immunological and vascular components that precede the actual onset of fibrosis, have become a matter of increasing scientific scrutiny. As a consequence, the field has started to realize that the early identification of this syndrome is crucial for optimal clinical care as well as for understanding its pathology. The cause of SSc cannot be appointed to a single molecular pathway but to a multitude of molecular aberrances in a spatial and temporal matter and on the backbone of the patient’s genetic predisposition. These alterations underlie the plethora of signs and symptoms which patients experience and clinicians look for, ultimately culminating in fibrotic features. To solve this complexity, a close interaction among the patient throughout its “journey,” the clinician through its clinical assessments and the researcher with its experimental design, seems to be required. In this review, we aimed to highlight the features of SSc through the eyes of these three professionals, all with their own expertise and opinions. With this unique setup, we underscore the importance of investigating the role of environmental factors in the onset and perpetuation of SSc, of focusing on the earliest signs and symptoms preceding fibrosis and on the application of holistic research approaches that include a multitude of potential molecular alterations in time in an unbiased fashion, in the search for a patient-tailored cure.     

Women’s use of online resources and acceptance of e-mental health tools during the perinatal period

ObjectivesThe women’s professional help-seeking rate for perinatal depression is low, despite the prevalent and disabling nature of this condition. Therefore, new approaches should be implemented to increase women’s access and utilization of treatment resources, namely e-mental health tools. This study aimed to characterize women’s current pattern of use of online resources for mental heal issues and women’s acceptance of e-mental health tools during the perinatal period, and to investigate its main determinants.MethodsThis study used an online cross-sectional survey that was completed by 546 women during the perinatal period.Results31.3% had prior knowledge of websites targeting mental health illness. Women presenting an actual need for help (i.e., a positive screen for depression) reported greater use of online resources and greater engagement in e-health behaviors related to mental health (d = 0.46–0.61), and being more accepting of e-mental health tools, particularly of informative websites. Women’s perceptions concerning the e-mental tools were found to predict their intentions to use them.ConclusionsThe results seem to globally support Portuguese women’s acceptance of e-mental health tools. To improve the level of acceptance, women should be involved as stakeholders in the development of new e-mental health tools and provided with specific information before their utilization.     

Maltoma of the thyroid and Sjögren’s syndrome in a woman with Hashimoto’s thyroiditis

We report the case of a 70-yr-old woman with maltoma of the thyroid, Sjögren’s syndrome, and a history of Hashimoto’s thyroiditis. The patient underwent a total thyroidectomy for a recently growing mass of the thyroid, while being treated with l-thyroxine for Hashimoto’s thyroiditis. Postoperatively, routine histologic examination was consistent with the diagnosis of chronic lymphocytic thyroiditis of autoimmune etiology. Three years later, the patient presented with high temperature, anorexia, and coughing. This time, a microscopic examination of deeper thyroid tissue sections and an immunohistochemical study revealed a low-grade, non-Hodgkin lymphoma, MALT type. Simultaneously, the diagnosis of Sjögren’s syndrome was established and the patient is currently under investigation for generalized lymphoma. This case clearly demonstrates the difficulty in differentially diagnosing Hashimoto’s thyroiditis from low-grade MALT lymphoma by the use of routine histologic examination.     

Metastatic Crohn’s disease accompanying granulomatous vasculitis and lymphangitis in the vulva

Metastatic Crohn’s disease (CD) is an extremely rare extragastrointestinal manifestation of CD, and is characterized histopathologically by the presence of non-caseating granulomatous inflammation. Granulomatous vasculitis and lymphangitis have rarely been documented in metastatic CD. Herein, we report the first documented case of metastatic CD accompanied by both granulomatous vasculitis and lymphangitis in the vulva. A 35-year-old Japanese female with CD presented with multiple small nodules in her vulva. Biopsy was performed under a clinical diagnosis of genital warts. A histopathological study revealed marked lymphangiectasia in the papillary dermis. Within the dilated lymphatics, lymphocytes and aggregates of macrophages were present, which are typical features of granulomatous lymphangitis. Tiny non-caseating granulomas and granulomatous vasculitis were also observed. Accordingly, a diagnosis of metastatic CD accompanied by both granulomatous vasculitis and lymphangitis was made. The occurrence of cutaneous lesions in patients with CD is well known. Albeit extremely rare, lymphangiectasia has been reported in the vulva of CD patients that clinically mimicked viral warts, as in the present case. The diagnosis of metastatic CD in the present case was not difficult because characteristic histopathological features were present, and a clinical history of CD was available. However, a few cases of genital swelling associated with granulomatous inflammation prior to a diagnosis of gastrointestinal CD have been documented. Therefore, granulomatous vasculitis and lymphangitis in the external genitals should be considered as potential indication of metastatic CD even in cases without a history of gastrointestinal CD.     

Activity of the leukotriene pathway in Barrett’s metaplasia and oesophageal adenocarcinoma

Objective

Leukotriene (LT) B₄ is a lipid inflammatory mediator implicated in tumorigenesis in animal models of Barrett’s oesophagitis, but little is known about the cysteinyl-leukotrienes (LTC₄, LTD₄, LTE₄), which have distinct inflammatory and tumorigenic actions in other tissues. We recently showed that the terminal enzymes for the synthesis of both LT families are highly expressed in human oesophageal adenocarcinoma (OA) tissues. This study therefore examined the capacity of Barrett’s metaplasia (BM) and OA tissues to synthesise LTs in vitro.

Subjects and methods

Oesophageal biopsies from patients with BM (n?=?14), high-grade dysplasia (n?=?2), OA (n?=?11), and squamous control tissues (n?=?11) were cultured with calcium ionophore A32187 (2?μM) for 60?min. LTB₄ and cysteinyl-leukotrienes were extracted and measured by specific enzyme immunoassays.

Results

Levels of LTB₄ and cysteinyl-leukotrienes were 8.6-fold (P?<?0.01) and 2.4-fold (P?<?0.02) higher, respectively, in OA tissues than in squamous control tissues, but levels in BM tissues (n?=?14) were not altered. Production of the two LT families correlated across all tissue types (r?=?0.62, p?<?0.00005).

Conclusions

Increased synthesis of LTB₄ and cysteinyl-leukotrienes has not previously been shown in human OA tissue and our results may indicate a role of these lipids in Barrett’s disease progression.     

Saccadic latency distributions in Parkinson’s disease and the effects of l-dopa

Parkinson’s disease (PD) is associated with a loss of central dopaminergic pathways in the brain leading to an abnormality of movement, including saccades. In PD, analysis of saccadic latency distributions, rather than mean latencies, can provide much more information about how the neural decision process that precedes movement is affected by disease or medication. Subject to the constraints of intersubject variation and reproducibility, latency distribution may represent an attractive potential biomarker of PD. Here we report two studies that provide information about these parameters, and demonstrate a novel effect of dopamine on saccadic latency, implying that it influences the neural decision process itself. We performed a detailed cross-sectional study of saccadic latency distributions during a simple step task in 22 medicated patients and 27 age-matched controls. This revealed high intersubject variability and an overlap of PD and control distributions. A second study was undertaken on a different population specifically to investigate the effects of dopamine on saccadic latency distributions in 15 PD patients. l-dopa was found to prolong latency, although the magnitude of the effect varied between subjects. The implications of these observations for the use of saccadic latency distributions as a potential biomarker of PD are discussed, as are the effects of l-dopa on neural decision making, where it is postulated to increase the criterion level of evidence required before the decision to move is made.RHS Carpenter and RA Barker are joint senior authors for this paper     

Critical amino acid variants in HLA-DRB1 allotypes in the development of Graves’ disease and Hashimoto’s thyroiditis in the Japanese population

The effects of amino acid variants encoded by human leukocyte antigen (HLA) class II on the development of Graves’ disease (GD) and Hashimoto’s thyroiditis (HT) have not been fully elucidated. We investigated the HLA-DRB1 genes of 243 GD patients and 82 HT patients in the Japanese population and compared the frequencies of HLA-DRB1 alleles and HLA-DRB1 amino acid variants between these patients and the Japanese populations previously reported by another institution. The frequencies of HLA-DRB1*04:05 and -DRB1*14:03 alleles were significantly higher and those of HLA-DRB1*01:01 and -DRB1*15:02 alleles were lower in GD patients than in controls. The frequencies of HLA-DRB1*08:03 and -DRB1*09:01 alleles were significantly higher and that of the HLA-DRB1*13:02 allele was lower in HT patients than in controls. A blind association analysis with all amino acid positions identified DRß9 and DRß31 for GD and DRß9, DRß13, and DRß21 for HT. The frequency of Glu-9 was significantly higher and that of Cys-9 was lower in GD patients than in controls. The frequencies of Lys-9 and Phe-13 were significantly higher in HT patients than in controls. DRß9 and DRß13 could be critical amino acid positions in the development of GD and HT.     

Shared perturbations in the metallome and metabolome of Alzheimer’s,Parkinson’s,Huntington’s,and dementia with Lewy bodies: A systematic review

Despite differences in presentation, age-related dementing diseases such as Alzheimer’s (AD), Parkinson’s (PD), and Huntington’s diseases (HD), and dementia with Lewy bodies (DLB) may share pathogenic processes. This review aims to systematically assemble and compare findings in various biochemical pathways across these four dementias.PubMed and Google Scholar were screened for articles reporting on brain and biofluid measurements of metals and/or metabolites in AD, PD, HD, or DLB. Articles were assessed using specific a priori-defined inclusion and exclusion criteria. Of 284 papers identified, 198 met criteria for inclusion.Although varying coverage levels of metals and metabolites across diseases and tissues made comparison of many analytes impossible, several common findings were identified: elevated glucose in both brain tissue and biofluids of AD, PD, and HD cases; increased iron and decreased copper in AD, PD and HD brain tissue; and decreased uric acid in biofluids of AD and PD cases. Other analytes were found to differ between diseases or were otherwise not covered across all conditions.These findings indicate that disturbances in glucose and purine pathways may be common to AD, PD, and HD. However, standardisation of methodologies and better coverage in some areas – notably of DLB – are necessary to validate and extend these findings.
