Genetic variants in the mammalian target of rapamycin (mTOR) signaling pathway as predictors of survival and clinical response in women with ovarian cancer

Background. The mTOR pathway is commonly altered in human tumors and promotes cell survival and proliferation. Preliminary evidence suggests this pathway's involvement in chemoresistance to platinum and taxanes, first line therapy for epithelial ovarian cancer. A pathway-based approach was used to identify individual germline single nucleotide polymorphisms (SNPs) and cumulative effects of multiple genetic variants in mTOR pathway genes and their association with clinical outcome in women with ovarian cancer. ^ Methods. The case-series was restricted to 319 non-Hispanic white women with high grade ovarian cancer treated with surgery and platinum-based chemotherapy. 135 SNPs in 20 representative genes in the mTOR pathway were genotyped. Hazard ratios (HRs) for death and Odds ratios (ORs) for failure to respond to primary therapy were estimated for each SNP using the multivariate Cox proportional hazards model and multivariate logistic regression model, respectively, while adjusting for age, stage, histology and treatment sequence. A survival tree analysis of SNPs with a statistically significant association (p<0.05) was performed to identify higher order gene-gene interactions and their association with overall survival. ^ Results. There was no statistically significant difference in survival by tumor histology or treatment regimen. The median survival for the cohort was 48.3 months. Seven SNPs were significantly associated with decreased survival. Compared to those with no unfavorable genotypes, the HR for death increased significantly with the increasing number of unfavorable genotypes and women in the highest risk category had HR of 4.06 (95% CI 2.29–7.21). The survival tree analysis also identified patients with different survival patterns based on their genetic profiles. 13 SNPs on five different genes were found to be significantly associated with a treatment response, defined as no evidence of disease after completion of primary therapy. Rare homozygous genotype of SNP rs6973428 showed a 5.5-fold increased risk compared to the wild type carrying genotypes. In the cumulative effect analysis, the highest risk group (individuals with ≥8 unfavorable genotypes) was significantly less likely to respond to chemotherapy (OR=8.40, 95% CI 3.10–22.75) compared to the low risk group (≤4 unfavorable genotypes). ^ Conclusions. A pathway-based approach can demonstrate cumulative effects of multiple genetic variants on clinical response to chemotherapy and survival. Therapy targeting the mTOR pathway may modify outcome in select patients.^

Systematic review of current trends of cardiovascular disease (CVD) and association between health insurance coverage and CVD mortality among women aged 60--65 in Texas in 2000--2011

Cardiovascular disease (CVD) is highly preventable, yet it is a leading cause of death among women in Texas. The primary goals of this research were to examine past and current trends of CVD, as well as identify whether there is an association between the insurance coverage and mortality from CVD among women aged 60–65 in Texas between 2000 and 2011. ^ The systematic review of the research is based on the guidelines and recommendations set by the Centre for Reviews and Dissemination for conducting reviews in health care. Over 47 citations of peer-reviewed articles from Ovid MEDLINE and PubMed databases and five websites were identified, of which 7 studies met inclusion criteria for the first systematic review to examine the trends of CVD in Texas. Ten citations of peer-reviewed articles from Ovid MEDLINE and PubMed databases and five web sites were reviewed for the second systematic review (to study the association between insurance coverage and cardiovascular health among Texas women 60–64 years of age), of which 3 studies met inclusion criteria and were included in the research. The results of the study highlighted key gaps in the existing literature and important areas for the further research, as well as determined directions for future public health CVD prevention programs in Texas. ^ Based on the conducted research, the major determinants of premature mortality among women attributed to cardiovascular disease are based on individual level characteristics, more specifically sex, age, race/ethnicity, and education. The results indicate that African American and non-Hispanic white women are more likely to have higher CVD mortality rates than Hispanic women due to higher prevalence of cardiac risk factors. The data also shows higher levels of mortality from CVD in the southeastern United States, with Texas ranking as the third state with the highest prevalence of CVD among women. According to the Texas Department of State Health Services, there are approximately 56,000 deaths caused by CVD annually in Texas, which represents about one death every ten minutes. Coronary artery disease and stroke were the causes of 31.2 percent of all female deaths in Texas in 2009, meaning that approximately 68 women die from any form of cardiac disease in Texas each day. ^ The data of the reviewed studies indicate that women' lack of health insurance was significantly associated with a higher prevalence of cardiovascular disease. The uninsured women were more likely to be unaware of their risk factors and more likely to have undiagnosed diabetes—a co-morbidity factor of CVD. One of the studies also reports strong correlation between state rates of uninsured and lower rates of preventive care. Given these strong correlations, those who were chronically uninsured were at a higher risk of mortality than the insured, due to prolonged periods of time without basic access to preventive and medical care. ^ Suggested recommendations to decrease CVD mortality rates in Texas are consistent with the existing literature and include state policy development that addresses elimination of health disparities, consideration of potential benefits of universal health coverage by the legislative policymakers, and maintenance of solid partnerships between public health agencies and hospitals to educate on, diagnose, and treat CVD among the female population in Texas. ^

Attentional processes associated with victimization history and posttraumatic symptomatology in women exposed to intimate partner violence

Exposure to intimate partner violence (IPV) puts women at risk for severe and chronic physical and mental health consequences, including elevations in IPV-related psychopathology and increased risk for future victimization. Previous research has examined attention as one of the key information processing mechanisms associated with elevated psychopathology and risk for victimization; however, the nature of attentional processing in response to IPV-related information in women exposed to IPV is poorly understood. Therefore, the current study aimed to further understanding of associations between attentional processing, IPV exposure, and related distress using measures of eye movement and subjective interpretations of IPV-related information. A sample of women exposed to IPV (n = 57) viewed sets of negative, positive, and neutral relationship images for 15 s each while having their eye movements monitored and later provided subjective ratings and interpretations of levels of risk and safety in those images. We examined associations of outcome measures with proximal victimization experiences and IPV-related psychopathology (i.e., depression, posttraumatic stress disorder (PTSD), anxiety, and dissociation). Results indicated a bias to attend to negative relationship images relative to positive and neutral images, though this attention bias fluctuated over time and varied as a function of symptomatology such that depression corresponded with increases in attention to negative images over time and PTSD corresponded with decreases in attention to negative images. The general attention bias for negative images appeared to be explained by rumination on and/or difficulty disengaging from negative images, which was related to general elevations in psychopathology as well as exposure to revictimization by different perpetrators. Subjective interpretations and perception of danger cues were related to victimization history and level and type of IPV-related distress. We replicated these procedures with a sample of undergraduate students without IPV histories or related symptomatology (n = 33) and found that the overall attention bias for negative images was not replicated, despite general similarities in patterns of attention over time. Results therefore indicated associations between attentional processing and IPV exposure and related symptomatology. Implications for models of IPV-related psychopathology and attentional processing as well as directions for future study and interventions are discussed.

The Relationship Between Weight Restoration and Maturity Fears in Women with Anorexica Nervosa

High maturity fears predict poor treatment outcomes in women with anorexia nervosa (AN). The purpose of this study was to determine if weight gain predicts decreases in maturity fears (MF) for AN patients. Fifty-six patients in an eating disorders partial hospitalization program were administered a series of psychological tests at intake and discharge. R2 values indicate that percent change in weight restoration will not accurately forecast the change in MF scores, although a positive trend was identified between the two variables. The weak predictive relationship suggests that weight restoration alone is not adequate to address the psychological components of AN.

Relationship between body mass index and mean arterial pressure in normotensive and chronic hypertensive pregnant women: a prospective, longitudinal study

Being overweight is associated with both higher systolic blood pressure (SBP) and diastolic blood pressure (DBP) during pregnancy and increased risk of gestational hypertensive disorders. The objective of this study was to determine and quantify the effect of body mass index (BMI) on mean arterial pressure (MAP) at several time points throughout pregnancy in normotensive (NT) and chronic hypertensive pregnant (HT) women.
