Influence of the BDNF Val66Met polymorphism on coping response to stress in patients with advanced gastric cancer

Objective

Coping with cancer is an important determinant of psychological morbidity, quality of life, and treatment adherence in cancer patients. The aim of this study was to elucidate the association between the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism and coping response to stress in patients diagnosed with advanced gastric cancer.

Methods

Ninety-one subjects (60 males, 31 females) recently diagnosed with advanced gastric cancer were recruited. Coping style and distress level were examined using the Mini-Mental Adjustment to Cancer (Mini-MAC) scale and Hospital Anxiety and Depression Scale, and genotyping was evaluated. To examine the temporal stability of the Mini-MAC scores, a 6-week follow-up evaluation was conducted in 72 patients, after completion of two chemotherapy cycles.

Results

Coping style to cancer significantly differed between the Met carriers of BDNF Val66Met and the Val/Val homozygotes. The Met carriers were significantly more anxious than the Val/Val homozygotes.

Conclusion

The present findings suggest that the BDNF Val66Met polymorphism may be involved in individual coping responses to cancer. The Met allele of BDNF Val66Met may be predictive of an anxious coping style in patients with advanced cancer.     

Changes in masticatory mandibular movements in growing individuals: a six-year follow-up

The pattern of mandibular movement during chewing is influenced by several central and peripheral factors. The aim of the present study was to determine whether changes in masticatory function, characterized by mandibular velocity and displacement, occurred during individuals' normal growth. Forty-seven children, 9-15 years of age, were followed over a 6-year period. All had an Angle Class I occlusion with no obvious orthodontic problems. Oral motor function with respect to mandibular displacement, duration, and velocity was monitored 3-dimensionally with an opto-electronic method. The chewing cycle was divided into an opening, closing, and occlusal phase. Total body height was measured. During the follow-up period, all masticatory variables except the 3-dimensional opening distance showed significant changes. The total chewing cycle duration, the opening and occlusal time of the chewing cycle, and the 3-dimensional closing distance increased during the growth period, while the closing time of the chewing cycle, the 2-dimensional lateral and vertical distances and both the opening and closing velocity decreased. The children who grew proportionally most in height during the 6-year period, i.e. the youngest children in the group studied, showed a significantly larger decrease in the opening velocity. From this study it becomes evident that the variables of the chewing cycle undergo a continuous process of change during growth. This is possibly a reflection of anatomical changes, maturation of the central nervous system, and altered functional demands.     

Network participation for unpromoted female dentists in relation to psychosocial support

Studies have shown that female unpromoted general practice (GP) dentists have a taxing work situation with many problems related to their psychosocial work environment. This study aims to describe: 1) the participation of this group in organized network activity (support groups) in a region (Scania) in Sweden, 2) the sense of support compared with another organization and with a nationwide sample of GP dentists, and 3) the covariation of network participation with support. All unpromoted female dentists within the Public Dental Health Service (PDHS) in Scania received a questionnaire and 94% responded. Those participating in network activity ≥4 times a year constituted 12% of respondents. Cooperation between colleagues was lower than in the nationwide sample. Support from the PDHS was experienced as weak. It was not possible to explain why female unpromoted GP dentists participated ≥4 times a year, while those who felt lonely in their work were to a higher degree participants in a network. Almost 9 out of 10 reported being strengthened by the network both as a person and in a professional role. The female dentist was three times more likely to participate in a network if she had a male head of clinic. The main findings are a paucity of inter‐colleague contact and a lack of association between support and network participation. The many affirmative comments indicated that network participation might be a good coping strategy for unpromoted female GP dentists.     

Predictors of Health-related Quality of Life and Adjustment to Prostate Cancer During Active Surveillance

Background

Active surveillance (AS) is emerging as an alternative approach to limit the risk of overtreatment and impairment of quality of life (QoL) in patients with low-risk localised prostate cancer. Although most patients report high levels of QoL, some men may be distressed by the idea of living with untreated cancer.

Objective

To identify factors associated with poor QoL during AS.

Design, setting, and participants

Between September 2007 and March 2012, 103 patients participated in the Prostate Cancer Research International Active Surveillance (PRIAS) QoL study. Mental health (Symptom Checklist-90), demographic, clinical, and decisional data were assessed at entrance in AS. Health-related QoL (HRQoL) Functional Assessment of Cancer Therapy-Prostate version and Mini-Mental Adjustment to Cancer outcomes were assessed after 10 mo of AS.

Outcome measurements and statistical analysis

Multivariate logistic regression models were used to identify predictors of low (<25th percentile) HRQoL, adjustment to cancer, and a global QoL index at 10 mo after enrolment.

Results and limitations

The mean age of the study patients was 67 yr (standard deviation: ±7 yr). Lack of partner (odds ratio [OR]: 0.08; p = 0.009) and impaired mental health (OR: 1.2, p = 0.1) were associated with low HRQoL (p = 0.006; area under the curve [AUC]: 0.72). The maladaptive adjustment to cancer (p = 0.047; AUC: 0.60) could be predicted by recent diagnosis (OR: 3.3; p = 0.072). Poor global QoL (overall p = 0.02; AUC: 0.85) was predicted by impaired mental health (OR: 1.16; p = 0.070) and time from diagnosis to enrolment in AS <5 mo (OR: 5.52; p = 0.009). Influence of different physicians on the choice of AS (OR: 0.17; p = 0.044), presence of a partner (OR: 0.22; p = 0.065), and diagnostic biopsy with >18 core specimens (OR: 0.89; p = 0.029) were predictors of better QoL. Limitations of this study were the small sample size and the lack of a control group.

Conclusions

Factors predicting poor QoL were lack of a partner, impaired mental health, recent diagnosis, influence of clinicians and lower number of core samples taken at diagnostic biopsy. Educational support from physicians and emotional/social support should be promoted in some cases to prevent poor QoL.     

Associations of psychological thriving with coping efficacy,expectations for future growth,and depressive symptoms over time in people with arthritis

Objective

Psychological thriving reflects a trajectory of growth over time as opposed to scaling back expectations. Whether thriving is a product, precursor, or process of coping with arthritis-related limitations is unclear. We examined associations between thriving, coping efficacy, and expectations for future growth in individuals with arthritis, and the relations of thriving to depressive symptoms and retrospective perceptions of personal growth over a six-month period.

Methods

A sample of 423 people with arthritis completed measures of thriving, coping efficacy, depressive symptoms, and expectations for future growth; 168 individuals completed a six-month follow-up survey. Structural equation modeling analyses compared three possible models of psychological thriving, controlling for disease-related variables. Hierarchical regression analyses of the cross-lagged associations of thriving with retrospective perceptions of positive personal change and depressive symptoms were also conducted.

Results

Structural equation analyses suggest that the process model in which thriving and coping efficacy jointly predicted expectations for future growth best fit the data. Baseline thriving was also associated with retrospective perceptions of personal growth at follow-up and fewer depressive symptoms at baseline and follow-up, after controlling for disease-related variables.

Conclusion

Overall, these findings suggest that psychological thriving is synergistically related to coping efficacy, and to expectations for future growth and less depression, in people with arthritis. Importantly, our findings support the notion that psychological thriving is more than scaling back expectations, and that thriving may be an important quality to cultivate to address the burden of depression in people with arthritis.     

Associations of self-esteem,dysfunctional beliefs and coping style with depression in patients with schizophrenia: A preliminary survey

Psychological models of depression in schizophrenia have proposed that cognitive structures (e.g., self-esteem, dysfunctional beliefs) may have a role in the development and maintenance of depression. However, it has not been clear what the characteristics of these cognitive structures were in people with schizophrenia and whether they have an independent association with depression, especially in those from a Chinese cultural background. The present investigation examined 133 people with schizophrenia and 50 healthy controls and indicated that compared to the controls people with schizophrenia showed lower self-esteem, higher levels of dysfunctional beliefs and negative coping styles. Multiple linear regression analysis revealed that only low frustration tolerance, problem solving and self-blame were found to be the independent correlates of depression in schizophrenia. Results are discussed with the view of clinical implications of cognitive formulation and therapy for schizophrenia in China.     

Premenstrual symptom clusters and women’s coping style in Korea: happy healthy 20s application study

Introduction: The purpose of this study was to identify premenstrual symptom clusters; and to explore the differences in and effectiveness of coping strategies among symptom cluster groups.

Methods: Using the happy healthy 20s smartphone application, 349 women with premenstrual symptoms participated in the study. Premenstrual symptoms and health outcomes such as perceived health, depressive feelings, quality of life, suicidal ideation/attempts and coping strategies were explored. Factor analysis and silhouette analysis were used to identify premenstrual symptom clusters. Analysis of variance was used to explore the differences among symptom clusters in health outcomes and coping strategies.

Results: Three premenstrual symptom clusters were identified: general discomfort, negative affect and turmoil. Three symptom cluster groups experienced different health outcomes in perceived health, depressive feelings, quality of life and suicidal ideation. However, few differences were noted in participants’ engagement in coping strategies, frequencies and perceived effectiveness among women with different symptom clusters.

Discussion: Findings of this study support previous reports that women do not receive tailored care for their premenstrual symptoms. Learning about the symptom structure, women’s ways of coping, and perceived effectiveness is important in identifying the issues in current premenstrual symptoms management and providing tailored care.

Anxiety, depression and coping strategies in post-hysterectomy Chinese women prior to discharge

OBJECTIVE: This survey investigated the relationships among anxiety, depression, coping strategies and demographic characteristics of post-hysterectomy Chinese women before discharge and further determined the best predictors of anxiety and depression among this group. METHODS: The sample consisted of 105 women who were administered, 1-2 days prior to discharge, via one-to-one interview, the Zung Self-rating Anxiety Scale, the Zung Self-rating Depression Scale, the Brief COPE Scale and a demographic questionnaire. RESULTS: Only 1.9% of the participants experienced anxiety, while 4.8% experienced depression after having a hysterectomy. Active coping, positive reframing, planning, emotional support and venting were the most frequently used coping strategies. Significant positive and negative correlations were found among anxiety, depression, coping strategies and the demographic characteristics of the subjects. The best predictors of anxiety were self-blame, venting and medical payment. The best predictors of depression were self-blame and employment status. CONCLUSION: Self-blame was the predictor of both anxiety and depression. It implied that a patient's negative self-evaluation may influence both psychological status and mental health. The ways of medical payment and employment status were predictors of anxiety and depression respectively, both of which reflected the economic stress that affected the psychological status and quality of life of the Chinese women, post-hysterectomy, before discharge. The findings of this study indicate that care for Chinese women post-hysterectomy, before discharge, should address their physical, psychological, social and economic well-being.
