Background Death during pregnancy and postpartum in the United States is an issue of urgent and growing concern. Mortality from obstetric-related causes is on the rise, and pregnancy-associated homicide remains a leading cause of death. It is unknown how the context in which women live contributes to their risk of obstetric or violent death during pregnancy and the postpartum period. This study aimed to quantify incidence of mortality from obstetric-related causes and violent death during pregnancy and up to 1-year postpartum, and to identify associations between state-level violent crime rates and incidence of pregnancy-related mortality and pregnancy-associated homicide. Materials and Methods We conducted a retrospective, ecologic analysis of all pregnancy-associated homicides in 17 states participating in the National Violent Death Reporting System from 2011 to 2015. Dihydromyricetin Pregnancy-related mortality was identified by International Classification of Diseases-10 code for underlying cause of death in death records issued in the same states and years, data provided by the National Center for Health Statistics. We characterized decedents of both violent and nonviolent maternal death (n = 174 and 1,617, respectively). Five-year mortality ratios (deaths per 100,000 live births) were estimated for both pregnancy-related mortality and pregnancy-associated homicide in every state. Poisson regression models estimated associations between violent crime and maternal death, adjusting for area-level socioeconomic conditions. Results Both pregnancy-related mortality and pregnancy-associated homicide ratios were higher in states with higher rates of violent crime (relative risk [RR] = 1.05, 95% confidence interval [CI] = 1.01-1.12; RR = 1.17, 95% CI = 1.01-1.34, respectively). Conclusion Broad population-wide violence prevention efforts may help reduce incidence of maternal mortality from both obstetric and violent causes.Plexin domain containing 2 (PLXDC2) is expressed in endothelial cells of tumor stroma, neural progenitor cells, and pluripotent stem cells, but their respective tissue expression pattern is not fully understood. In this study, we investigated the expression pattern of PLXDC2 in human hepatocellular carcinoma (HCC) tissues using a highly specific anti-PLXDC2 rabbit monoclonal antibody, which was recently developed. PLXDC2 was expressed in human HCC tissues including HCC cells, tumor vascular endothelial cells, and some infiltrating cells. The developed anti-PLXDC2 antibody allowed for highly specific and low background staining. Based on these current findings of PLXDC2 expression in human HCC tissues, the window may now be open to explore the role of PLXDC2 in human HCC.Background The goal of this study was to characterize the thoracic duct (TD) both morphologically and hemodynamically. Materials and Methods The lymphatic flow and pressure gradient from the cisterna chyli (CC) to the lymphovenous junction were measured in anesthetized swine (n = 9). After the animals were euthanized, the TD were harvested for histomorphometric analyses in which three samples were perfused with 9% gelatin to obtain the morphometry of the TD valve in both the open and closed configuration. Spectral analyses were performed. An afferent lymphatic vessel of the CC was accessed and cannulated after the animal was euthanized for casting (n = 3) to obtain morphometric data. Results The in vivo flow rate was 0.7 ± 0.49 mL/minute. Spectral analysis (Fast Fourier Transformation) showed correlation coefficients of 0.858 ± 0.063 and 0.586 ± 0.112 (p  less then  0.05) for the TD and JVPs, respectively. The average pressure gradient was 8.1 mmHg along the TD. The length of the TD was 35.6 ± 2.2 cm. The maximal width of the CC ranged from 11.4 to 15 mm. The diameter of the TD varied irregularly from 2 to 4.3 mm. The geometry of the TD leaflets was determined to have an area of 1.99 ± 0.53 mm2, a leaflet length of 3.26 ± 0.86 mm, a packet depth of 0.66 ± 0.19 mm, and a wall length of 5.46 ± 2.16 mm. The TD media thickness was ∼7 ± 3 μm. The number of valves ranged from 9 to 13 in the full length of the TD. Conclusions A relatively constant pressure gradient in the swine TD drives lymph flow from the CC to the jugular vein. The TD is a thin-walled vessel with valves that prevent reflux of lymph flow. This study of morphometric and lymphatic dynamics is important for interventionalists to understand the anatomy and physiology of the TD to design new diagnostic, interventional procedures, and devices.The aim of this study is to evaluate the role of All-Trans Retinoic Acid, the biologically active metabolite of retinoids, on liver steatosis in a rabbit model of high fat induced lever steatosis. 30 male rabbits were evaluated in 5 groups group 1 treated with normal diet, group 2-5 included rabbit's groups 2 to 5 were fed on high cholesterol diet, group 2 received no drugs, group 3 received atorvastatin, group 4 received atRA, and group 5 received both the drugs. the liver was obtained for histopathological evaluation. oral administration of atRA, atorvastatin or their combination significantly decreased serum levels of total cholesterol, LDL, AST and ALT. atorvastatin slightly but atRA remarkably decreased liver steatosis where the difference was significant. atRA group showed the highest TAC and the lowest PCO concentrations. atRA can be effective in reducing liver steatosis and its antioxidant effect plays a crucial role in the process.HighlightsNon-alcoholic fatty liver disease (NAFLD) is the most common disorder of the liver in general population and is strongly associated with metabolic risk factors including hyperlipidaemia, obesity and diabetes.atRA is very effective in reducing liver steatosis and its antioxidant effect plays a crucial role in the process.we suggest focussing on other aspects of liver steatosis such as carbohydrate metabolism and insulin resistance in order to find better ways of controlling and treating liver steatosis.Little is known about the perceptions of sibling relationships from the direct perspective of service users with mental health difficulties; this study aimed to address this gap. Semi-structured interviews were carried out with adult male inpatients who had severe and enduring mental health difficulties. Interpretative phenomenological analysis was used to analyse the data and revealed three main themes (1) The closeness of the sibling bond; (2) The change in sibling dynamics following diagnosis and admission; (3) Siblings' contribution to mental health and recovery. The implications of involving siblings in care and the benefits of service user led research are discussed.Objectives Non-medical use of prescription drugs (NMUPD) has become a threat to public health. In the United States, NMUPD is especially common in young adults (aged 18-25). Self-esteem is a robust psychosocial factor of substance use. The substance use literature also documents that self-esteem is associated with alcohol use through other cognitive factors, such as coping. Given the important role of coping in substance use intervention, it is important to understand how coping alters mechanisms underlying the effects of self-esteem on NMUPD. However, little research has explored mediational mechanisms among self-esteem, coping, and NMUPD. The current study sought to examine a hypothesized mediation model among self-esteem, coping, and NMUPD in college students. Methods Data were collected online from 1052 undergraduates (aged 18 to 25; 723 females) in a large public university in Virginia. Participants reported their past-three-month NMUPD (i.e. opioids, sedatives, anxiolytics, and stimulants), self-esteem, and coping (13 domains; e.g. active coping and self-blame). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to identify the factorial structure of coping. Structural equation modeling (SEM) was employed for examining the hypothesized mediation model. Results EFA and CFA identified a two-factor structure of coping (i.e. adaptive coping and maladaptive coping). SEM suggested that adaptive coping together with maladaptive coping completely mediated the relationship between self-esteem and NMUPD. The goodness-of-fit indicators suggest a good model fit (RMSEA = .04; CFI = .95; TLI = .93; WRMR = 1.11). Conclusion Self-esteem appears to be a protective factor for NMUPD in college students, and its relationship with NMUPD is mediated by two types of coping. Future interventions targetting NMUPD among college students should attend to self-esteem and coping.Antisense oligonucleotides (ASOs) are synthetic nucleic acids that recognize complementary RNA sequences inside cells and modulate gene expression. In this study, we explore the feasibility of ASO delivery to the cornea. We used quantitative polymerase chain reaction to test the efficacy of a benchmark ASO targeting a noncoding nuclear RNA, Metastasis-Associated Lung Adenocarcinoma Transcript 1 (MALAT1), in a human corneal endothelial cell line, ex vivo human corneas, and in vivo in mice. In vivo delivery was via intravitreal or intracameral injections as well as topical administration. The anti-MALAT1 ASO significantly reduced expression of MALAT1 in a corneal endothelial cell line. We achieved a dose-dependent reduction of target gene expression in endothelial tissue from ex vivo human donor corneas. In vivo mouse experiments confirmed MALAT1 reduction in whole corneal tissue via intravitreal and intracameral routes, 82% and 71% knockdown, respectively (P  less then  0.001). Effects persisted up to at least 21 days, 32% (P  less then  0.05) and 43% (P  less then  0.05) knockdown, respectively. We developed protocols for the isolation and analysis of mouse corneal endothelium and observed reduction in MALAT1 expression upon both intravitreal and intracameral administrations, 64% (P  less then  0.05) and 63% (P  less then  0.05) knockdown, respectively. These data open the possibility of using ASOs to treat corneal disease.Background Relative Psoriasis Area and Severity Index (PASI) improvement, also called "PASI response", is recommended in major guidelines for assessment of treatment response in psoriasis patients. However, under certain circumstances it has some limitations, e.g. when baseline values are missing or during long-term treatment. Improvement of health-related quality of life (HrQoL) can be measured by the Dermatology Life Quality Index (DLQI).Objective To evaluate the association of HrQoL and relative and absolute PASI outcomes during therapy.Materials and methods Data of plaque psoriasis patients of two clinical trials (CLEAR and SCULPTURE) were pooled. The rates of patients achieving DLQI 0/1 at week 16 were compared for different categories of absolute PASI and PASI response values. The correlation of DLQI and absolute or relative PASI goals was assessed over 52 weeks.Results 1,054 patients with available assessments of PASI and DLQI were included. 76% of the patients with an absolute PASI ≤2 (N = 548) and patients with a 90% improvement in PASI (N = 559) achieved DLQI0/1 at week 16. Achievement of DLQI0/1 was equally reflected by absolute PASI and PASI response.Conclusion Absolute PASI appeared to be a feasible alternative to PASI response for determining treatment success, reflecting HrQoL improvements in an equal manner.
