Do recent life events and social support explain gender differences in depressive symptoms in patients who had percutaneous transluminal coronary angioplasty?

Pharmacokinetics and dialytic clearance of apixaban during in vitro continuous renal replacement therapy

Background

To evaluate the transmembrane clearance (CL_TM) of apixaban during modeled in vitro continuous renal replacement therapy (CRRT), assess protein binding and circuit adsorption, and provide initial dosing recommendations.

Methods

Apixaban was added to the CRRT circuit and serial pre-filter bovine blood samples were collected along with post-filter blood and effluent samples. All experiments were performed in duplicate using continuous veno-venous hemofiltration (CVVH) and hemodialysis (CVVHD) modes, with varying filter types, flow rates, and point of CVVH replacement fluid dilution. Concentrations of apixaban and urea were quantified via liquid chromatography-tandem mass spectrometry. Plasma pharmacokinetic parameters for apixaban were estimated via noncompartmental analysis. CL_TM was calculated via the estimated area under the curve (AUC) and by the product of the sieving/saturation coefficient (SC/SA) and flow rate. Two and three-way analysis of variance (ANOVA) models were built to assess the effects of mode, filter type, flow rate, and point of dilution on CL_TM by each method. Optimal doses were suggested by matching the AUC observed in vitro to the systemic exposure demonstrated in Phase 2/3 studies of apixaban. Linear regression was utilized to provide dosing estimations for flow rates from 0.5–5 L/h.

Results

Mean adsorption to the HF1400 and M150 filters differed significantly at 38 and 13%, respectively, while mean (± standard deviation, SD) percent protein binding was 70.81 ± 0.01%. Effect of CVVH point of dilution did not differ across filter types, although CL_TM was consistently significantly higher during CRRT with the HF1400 filter compared to the M150. The three-way ANOVA demonstrated improved fit when CL_TM values calculated by AUC were used (adjusted R² 0.87 vs. 0.52), and therefore, these values were used to generate optimal dosing recommendations. Linear regression revealed significant effects of filter type and flow rate on CL_TM by AUC, suggesting doses of 2.5–7.5 mg twice daily (BID) may be needed for flow rates ranging from 0.5–5 L/h, respectively.

Conclusion

For CRRT flow rates most commonly employed in clinical practice, the standard labeled 5 mg BID dose of apixaban is predicted to achieve target systemic exposure thresholds. The safety and efficacy of these proposed dosing regimens warrants further investigation in clinical studies.

Study on the psychological health and related risk factors in 245 patients with psoriasis in Inner Mongolia

To investigate the psychological health and related risk factors in patients suffering from psoriasis. A total of 245 inpatients and outpatients with psoriasis were selected from January 2014 to December 2015. Patients with psoriasis were assessed a homemade questionnaire as well as the Psoriasis Area and Severity Index (PASI), Selfrating Anxiety Scale, Self-rating Depression Scale, Trait Coping Style Questionnaire and Social Avoidance and Distress Scale.Differences in sex, age, marital status, type of medical payment, occupation, economic situation, disease severity, and type of psychological state of psoriasis patients were significant, there was no significant difference in psychological health between psoriasis patients with different levels of educational attainment. Scores for anxiety, depression, social avoidance, and social distress were positively correlated with disease severity and negative-coping scores, but a significant negative correlation was observed with scores for social support and positive coping. Stepwise regression analysis of factors influencing psychological health showed that total social support and negative-coping scores could explain 65.2% of the variation. Patients with psoriasis can suffer from anxiety, depression, social distress, and social avoidance. Physicians should pay greater attention to deterioration in mental health of psoriasis patients.

Individual, Social, and Societal Correlates of Health-Related Quality of Life Among African American Survivors of Ovarian Cancer: Results from the African American Cancer Epidemiology Study

OBJECTIVE

While the incidence of epithelial ovarian cancer (EOC) is lower among African American (AA) women compared with European American (EA) women, AA women have markedly worse outcomes. In this study, we describe individual, social, and societal factors in health-related quality of life (HRQL) in AA women diagnosed with EOC in the African American Cancer Epidemiology Study (AACES) that we hypothesize may influence a patient's capacity to psychosocially adjust to a diagnosis of cancer.

METHODS

There were 215 invasive EOC cases included in the analysis. HRQL was measured using the SF-8 component scores for physical (PCS) and mental (MCS) health. We used least squares regression to test the effects of individual dispositional factors (optimism and trait anxiety); social level (perceived social support); and societal-level factors (SES defined as low family income and low educational attainment, and perceived discrimination) on HRQL, while adjusting for patient age, tumor stage, body mass index, and comorbidity. Mediation analysis was applied to test whether social support and physical activity buffer impacts of EOC on HRQL.

RESULTS

Optimism, trait anxiety, social support, poverty, and past perceived discrimination were significantly associated with HRQL following diagnosis of EOC. Specifically, higher family income, lower phobic anxiety, and higher social support were associated with better wellbeing on the MCS and PCS (p < 0.01). Higher perceived discrimination was associated with both lower MCS and PCS, whereas higher optimism was associated with higher MCS. Physical activity (MET-min/week) and social support displayed significant overall mediation for effects of SES on MCS and PCS, but not for trait anxiety.

CONCLUSIONS

Both pre- and postdiagnosis characteristics of AA women with EOC are important predictors of HRQL after cancer diagnosis. Individual, social, and societal-level factors each contribute to HRQL status with EOC and should be assessed.

Health status and mental health in patients after percutaneous coronary intervention

OBJECTIVE

to assess the association between perceived health status and the mental health of patients submitted to percutaneous coronary intervention after hospital discharge.

METHOD

a quantitative and cross-sectional study involving 101 participants. The following instruments were used: a sociodemographic and clinical characterization instrument, the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and the Hospital Anxiety and Depression Scale (HADS). Participants were divided into three groups: no anxiety and no depression (G1); anxiety or depression (G2); and both (G3). The ANOVA test was used for the intergroup comparison of means on the SF-36 domains.

RESULTS

There was an association between perceived health status and mental health. The participants in G1 presented higher scores in all SF-36 domains in comparison with participants in G2 and G3.

CONCLUSION

Participants with no anxiety and depression presented better-perceived health status in comparison with those with anxiety or depression, or both.

[Anxiety and depression among men and women who underwent percutaneous coronary intervention]

A descriptive, cross-sectional, correlational study aimed to investigate the association of sex and the presence of anxiety and depression after hospital discharge in patients who underwent percutaneous coronary intervention (PCI). Fifty-nine patients undergoing PCI and receiving outpatient treatment in the first seven months after hospital discharge were evaluated. To assess the symptoms of anxiety and depression the Hospital Anxiety and Depression Scale (HADS) was used. To test the possible associations between the variables anxiety, depression and sex the Chi-square test was used with a significance level of 5%. The results indicated a greater number of women with depression and the association between the variables sex and depression was statistically significant. In relation to anxiety, cases were more frequent in males and the association between the variables sex and anxiety was not statistically significant.

Relation of depression, anxiety, and quality of life with outcome after percutaneous transluminal coronary angioplasty

Background. Despite, increasing number of percutaneous transluminal coronary angioplasty (PTCA) being performed, there is a paucity of Indian studies on the psychological effects of PTCA. Aim. To study the relation of anxiety, depression, and health related quality of life with outcome after PTCA. Methods. A total of 35 patients undergoing PTCA were included in the present project with their informed consent. All patients filled a specially designed proforma, the Hospital Anxiety and Depression Scale, Coronary Scale, Seattle Angina Questionnaire, and a health related quality of life measure (EQ 5D) one day before undergoing PTCA. Three days after PTCA patients were reassessed with the Hospital anxiety & depression scale, Seattle angina questionnaire and the EQ 5D. Results. Analysis showed that 46% had significant anxiety and 32.1% had significant depression before PTCA. Following successful PTCA, none of the patients had significant anxiety, and only 2 (3.6%) had significant depression. On the Seattle Angina Questionnaire, physical limitation reduced from 67.9 to 48. Disease perception improved from 21.2 to 37.1. On the EQ5D, the health status improved from 42.7 before PTCA to 78.7 after PTCA. Conclusion. Successful PTCA resulted in significant reduction in anxiety, depression, and physical limitation and improvement in disease perception and health status.

Social support and adaptation to the disease in men and women with psoriasis

Social support was shown to be an important factor buffering negative effects of stress in a range of clinical populations. Little is known, however, about the role of social support in the population of patients with psoriasis although strong psychosocial stress has been implicated in this disease. The objective of this study was to evaluate the association between social support and selected indices of adaptation to life with the disease, including health-related quality of life, depressive symptoms and acceptance of life with the disease, in a sample of patients with psoriasis. Additionally, gender differences in these relationships were analyzed. One-hundred-four patients with psoriasis completed psychological tests measuring disease-related social support, health-related quality of life, depressive symptoms and acceptance of life with the disease. Psoriasis severity was assessed by Psoriasis Area and Severity Index. The patients reporting higher social support levels had significantly higher quality of life, lower depression levels, and higher acceptance of life with the disease. The strengths of these effects, however, were different in women and men. Higher social support was slightly more closely associated with better acceptance of life with the disease in men than in women. However, higher social support was more closely associated to lower depression and better quality of life in women than in men. Among different types of social support, tangible support was found to be the best predictor for the all adaptation indices. Effects of social support perceived by psoriasis patients on adaptation to the disease may be gender-related and exact pathways of these effects may depend on the type on the dimension of social support and the selected type of adaptation indicator. Tangible support seems the most important type of support contributing to better adaptation in both women and men with psoriasis.
