Participants experienced these interactions as being treated differently than men and/or being stereotyped. As their careers progressed, participants recognized gender inequity as embedded in the organization, or as they said, "the way things were stacked". Subsequent to this recognition, they navigated this gendered organization by advocating for themselves and younger women faculty. Insights Women with established careers in academic medicine experienced gender inequity as embedded in the organization but navigate gendered interactions by advocating for themselves and for younger women. Using the Theory of Gendered Organizations as an analytic lens demonstrates how academic medical centers function as gendered organizations; these findings can inform both theory-based research and pragmatic change strategies.Objective To investigate the associations between serum vitamin D, calcium and uterine fibroids in a Chinese female population. Methods In this case-control study, adult female patients with fibroids (cases) were compared with females without fibroids (controls) in terms of serum 25-hydroxyvitamin D (25OHD) and calcium levels. Results Out of 546 total participants (mean age, 41.68 ± 5.99 years; 279 with fibroids and 267 without fibroids), only 232 had serum 25OHD levels above the sufficient threshold (>20 ng/ml). In addition, females with fibroids had lower serum 25OHD levels versus those without fibroids. The prevalence of fibroids in females with deficient (20 ng/ml) 25OHD levels. Serum calcium levels were within normal range in both groups. Conclusion Hypovitaminosis D was highly prevalent among a population of Chinese females of reproductive-age, and serum 25OHD levels were lower in female patients with fibroids.Reactive oxygen species (ROS) such as superoxide, hydroxyl radical, and hydrogen peroxide play an important role in the maintenance of life. However, production of excessive ROS and/or deficiency of the antioxidant system lead to oxidative stress and cause a variety of diseases. In the present study, we used electron spin resonance (ESR) to detect ROS in vivo to clarify its roles in redox dynamics and organ damage. However, the limited permeability of microwaves and low anatomic resolution of ESR equipment made it difficult to apply clinically. Nitroxide is widely used as a sensitive redox sensor for in vivo ESR analysis. The unpaired electrons of nitroxide are known to cause the T1 relaxation time-shortening effect of water protons, creating magnetic resonance imaging (MRI) effects. The remarkable development of MRI has facilitated the spatiotemporal analysis of nitroxide, which was previously impossible. In a rat model, we have been able to image and analyze the process of nitroxide reduction using MRI. MRI using nitroxide as a contrast medium is considered to be clinically applicable for evaluation of organ redox, imaging of ROS (which cause organ damage), and evaluation of therapeutic effects. In this review, we describe current advances in the analysis of in vivo redox capacity in animals using ESR and MRI equipment. We consider that redox evaluation using MRI can contribute to advances in clinical medicine.HER2-positive breast cancer accounts for 18-20% of all breast cancers. GDC-0199 Despite significant advances and the currently available adjuvant treatments for management of the disease, approximately 25% of HER2-positive early-stage breast cancer patients show relapse and die. Neratinib is an irreversible tyrosine kinase inhibitor. Multiple studies have reported its significant antitumor activity in metastatic HER2-positive breast cancer. It is administered orally and has also been tested in the adjuvant setting. In this article, we present a comprehensive review of the pharmacokinetics and pharmacodynamics of neratinib as well as its clinical efficacy, with an emphasis on early HER2-positive breast cancer and suggestions for future directions for neratinib research.Background Patients prescribed opioids often have chronic conditions that increase their risk of adverse cardiovascular outcomes, but little is known about the primary preventive cardiovascular care these patients receive. Methods and Results We analyzed data from the 2014 to 2016 National Ambulatory Medical Care Survey to evaluate physicians' provision of primary preventive cardiovascular care to adults with and without opioid prescriptions. We included all visits made by adults 40 to 79 years old with at least 1 cardiovascular risk factor but no existing atherosclerotic cardiovascular disease. There were ≈32 million visits by adults who were prescribed opioids and ≈167 million visits by adults not prescribed opioids on an annual basis. The prevalence of primary preventive care was modest in patients with versus those without opioid prescriptions, respectively (1) statins for patients with dyslipidemia (52.1% versus 46.3%); (2) statins for patients with diabetes mellitus (49.1% versus 37.9%); (3) antihypertensive agents for patients with hypertension (76.5% versus 65.8%); (4) diet/exercise counseling (40.5% versus 45.3%); and (5) smoking cessation therapy (25.3% versus 19.3%). In multivariate analyses, opioid use was associated with higher rates of statin therapy in patients with diabetes mellitus (adjusted relative risk [aRR], 1.25; 95% CI, 1.06-1.47; P=0.007) and antihypertensive medication in patients with hypertension (aRR 1.14; 95% CI, 1.06-1.22; P less then 0.001). Conclusions Overall adherence to guideline-recommended primary preventive cardiovascular care during ambulatory visits was suboptimal. Findings show that patients prescribed opioids versus those without opioid prescriptions were more likely to receive statin therapy and antihypertensive agents in the setting of diabetes mellitus and hypertension, respectively. Ongoing efforts to bridge these gaps in primary prevention of cardiovascular disease remain a high priority.Here, we report a case of coexistence of a duplicate gallbladder and choledochal cyst, which was overlooked preoperatively and confirmed via intraoperative inspection and pathological examination. We concluded that a high index of suspicion is required to diagnose a double gallbladder, and special attention should be paid to preoperative radiological imaging when treating patients with choledochal cysts because these patients present a higher incidence of biliary anomalies.Significance Autoimmune diseases are progressively affecting westernized societies, as the proportion of individuals suffering from autoimmunity is steadily increasing over the past decades. Understanding the role of reactive oxygen species (ROS) in modulation of the immune response in the pathogenesis of autoimmune disorders is of utmost importance. The focus of this review is the regulation of ROS production within tolerogenic dendritic cells (tolDCs) and regulatory T (Treg) cells that have the essential role in the prevention of autoimmune diseases and significant potency in their therapy. Recent Advances It is now clear that ROS are extremely important for the proper function of both DC and T cells. Antigen processing/presentation and the ability of DC to activate T cells depend upon the ROS availability. Treg differentiation, suppressive function, and stability are profoundly influenced by ROS presence. Critical Issues Although a plethora of results on the relation between ROS and immune cells exist, it remains unclear whether ROS modulation is a productive way for skewing T cells and DCs toward a tolerogenic phenotype. Also, the possibility of ROS modulation for enhancement of regulatory properties of DC and Treg during their preparation for use in cellular therapy has to be clarified. Future Directions Studies of DC and T cell redox regulation should allow for the improvement of the therapy of autoimmune diseases. This could be achieved through the direct therapeutic application of ROS modulators in autoimmunity, or indirectly through ROS-dependent enhancement of tolDC and Treg preparation for cell-based immunotherapy.Background Synchronous and antisynchronous activity between neural elements at rest reflects the physiological processes underlying complex cognitive ability. Regional and pairwise-connectivity investigations suggest perturbations in these activity patterns may relate to widespread cognitive impairments seen in bipolar disorder (BD). Here we take a network-based perspective to more meaningfully capture interactions among distributed brain regions compared to focal measurements and examine network-cognition relationships across a range of commonly affected cognitive domains in BD in relation to healthy controls. Methods Resting-state networks were constructed as matrices of correlation coefficients between regionally averaged resting-state time series from 86 cortical/subcortical brain regions (FreeSurferv5.3.0). Cognitive performance measured using Weschler Adult Intelligence Scale, Cambridge Automated Neuropsychological Test Battery (CANTAB) and Reading the Mind in the Eyes tests was examined in relation to ognition are found, while distinct functional networks supporting episodic and spatial memory highlight intrinsic inhibitory influences present in the resting-state that facilitate memory processing.Background The nodal brain network measures (e.g. centrality measures) are defined for a single node and the global network measures (e.g. global efficiency) are defined for the whole brain in the literature. But a meaningful group of nodes will be benefited from a formulation that applies to a group of nodes rather than a single node or the whole brain. The question like "which brain-lobe is more structurally central in the older-adult brain?" could be answered to some extent by the application of a centrality measure that applied to the group of nodes from each lobe. In the brain asymmetric studies, path-based global measures were applied to the left and right hemispherical networks separately, considering only intra-hemispheric edges. However, for a valid comparison, such global measures should include the inter-hemispheric edges as well. This problem can be solved by considering both hemispherical nodes as two groups in one network. Methods Novel definitions for group nodes network measures are presented here, to solve a number of such group-context problems in the brain networks analysis. We apply the group measures to the structural connectomes of older-adults and Alzheimer's disease (AD) subjects based on the brain-lobes and hemispherical groups to demonstrate the effectiveness of the proposed measures. Results The temporal and parietal lobes are the most central lobes in older-adults and AD, but the strength of these lobes has been heavily affected in AD. However, the rewiring of the AD brain preserves the paths for communication between other regions through these lobes. Leftward efficiency revealed in older-adults and the asymmetry disappeared in the rewired AD. Conclusion We prove that the concepts of group network measures have the potential to solve a number of such group-context problems in the brain networks analysis and the group network measures change the way of analysing brain networks.Purpose This study aims to investigate the impact of disadvantaged neighborhoods and lifestyle factors on obesity among Australian adults. Design Quantitative, longitudinal research design. Setting Cohort. Sample Data for this study came from a cohort of 10 734 adults (21 468 observations) who participated in the Household, Income and Labour Dynamics in Australia survey. The participants were interviewed at baseline in 2013 and were followed up in 2017. Measures Generalized Estimating Equation model with logistic link function was employed to examine within-person changes in obesity due to disadvantaged neighborhoods and lifestyle factors at 2-time points over a 4-year follow-up period. Results Adults living in the most disadvantaged area were 1.22 (odds ratio [OR] 1.22, 95% CI 1.08-1.38) and 1.30 (OR 1.30, 95% CI 1.20-1.42) times, respectively, more prone to be overweight and obese compared with peers living at least disadvantaged area. Study results also revealed that adults who consume fruits regularly and perform high levels of physical activity were 6% (OR 0.
