Purpose Prior research examining the impact of androgen deprivation therapy (ADT) for prostate cancer on cognitive performance has found inconsistent relationships. The purpose of this study was to systematically review the existing literature and determine the effect of ADT on performance across seven cognitive domains using meta-analysis. Methods A search of PubMed Medline, PsycINFO, Cochrane Library, and Web of Knowledge/Science databases yielded 157 unique abstracts reviewed by independent pairs of raters. Fourteen studies with a total of 417 patients treated with ADT were included in the meta-analysis. Objective neuropsychological tests were categorized into seven cognitive domains: attention/working memory, executive functioning, language, verbal memory, visual memory, visuomotor ability, and visuospatial ability. Results Separate effect sizes were calculated for each cognitive domain using pairwise comparisons of patients who received ADT with 1) prostate cancer patient controls, 2) non-cancer controls, or 3) ADT patients’ own pre-ADT baselines. Patients treated with ADT performed worse than controls or their own baseline on visuomotor tasks (g=−0.67, p=.008; n=193). The magnitude of the deficits was larger in studies with a shorter time to follow-up (p=.04). No significant effect sizes were observed for the other six cognitive domains (p=.08=–.98). Conclusions Prostate cancer patients who received ADT performed significantly worse on visuomotor tasks compared to non-cancer control groups. These findings are consistent with the known effects of testosterone on cognitive functioning in healthy men. Knowledge of the cognitive effects of ADT may help patients and providers better understand the impact of ADT on quality of life.

Background Community health workers (CHWs) are lay individuals who are trained to serve as liaisons between members of their communities and healthcare providers and services. Methods A systematic review was conducted to synthesize evidence from all prospective controlled studies on effectiveness of CHW programs in improving screening mammography rates. Studies reported in English and conducted in the United States were included if they: (1) evaluated a CHW intervention designed to increase screening mammography rates in women 40 years of age or older without a history of breast cancer; (2) were a randomized controlled trial (RCT), case-controlled study, or quasi-experimental study; and (3) evaluated a CHW intervention outside of a hospital setting. Results Participation in a CHW intervention was associated with a statistically significant increase in receipt of screening mammography [Risk Ratio (RR):1.06 (favoring intervention); 95% Confidence Interval (CI:1.02, 1.11),p=0.003]. The effect remained when pooled data from only RCTs were included in meta-analysis (RR:1.07,95% CI:1.03,1.12,p=0.0005), but was not present using pooled data from only quasi-experimental studies (RR:1.03,95% CI:0.89,1.18,p=0.71). In RCTs, participants recruited from medical settings (RR:1.41,95% CI:1.09,1.82,p=0.008), programs conducted in urban settings (RR:1.23,95% CI:1.09,1.39,p=0.001), and programs where CHWs were matched to intervention participants on race or ethnicity (RR:1.58, 95%CI:1.29,1.93,p=0.0001) demonstrated stronger effects on increasing mammography screening rates. Conclusions CHW interventions are effective for increasing screening mammography in certain settings and populations. Impact CHW interventions are especially associated with improvements in rate of screening mammography in medical settings, urban settings, and in participants who are racially or ethnically concordant with the CHW.

To be effective, stress management interventions for Latinas receiving chemotherapy may necessitate more attention from an interventionist, delivery of the intervention over a longer interval, and/or a group-based format.

Evidence is mixed regarding the effects of hematopoietic cell transplantation (HCT) on changes in cognitive functioning among adults. Meta-analysis, which is designed to help reconcile conflicting findings, has not yet been conducted on studies of adults receiving HCT. To fill this gap, the current study provides a systematic review and meta-analysis of cognitive functioning in adults receiving HCT. A search of PubMed, PsycInfo, CINAHL, and Cochrane Library yielded 732 abstracts, which were independently evaluated by pairs of raters. Seventeen studies were systematically reviewed; eleven were retained for meta-analysis. There was agreement that cognitive impairments are evident for a subset of patients prior to HCT. Meta-analytic findings of 404 patients revealed no significant changes in cognitive functioning pre- to post-HCT (P values > .05). Age, time since transplant, and total body irradiation were not associated with changes in cognitive functioning. Patients who received autologous transplants were more likely to demonstrate improvements in attention (P = .004). The systematic review identified several limitations of existing literature, including small, clinically heterogeneous samples. Large, cooperative group studies are needed to address these design limitations. Nevertheless, results from the current meta-analysis suggest that cognitive functioning does not significantly change following HCT.

Objective Fatigue is common among cancer patients and adversely impacts quality of life. As such, it is important to measure fatigue accurately in a way that is not burdensome to patients. The 7-item Patient Reported Outcome Measurement Information System (PROMIS) Cancer Fatigue Short Form scale was recently developed using item response theory (IRT). The current study evaluated the psychometric properties of this scale in two samples of cancer patients using classical test theory (CTT). Methods Two samples were used: 121 men with prostate cancer and 136 patients scheduled to undergo hematopoietic cell transplantation (HCT) for hematologic cancer. All participants completed the PROMIS Cancer Fatigue Short Form as well as validated measures of fatigue, vitality, and depression. HCT patients also completed measures of anxiety, perceived stress, and a clinical interview designed to identify cases of cancer -related fatigue. Results PROMIS Cancer Fatigue Short Form items loaded on a single factor (CFI = 0.948) and the scale demonstrated good internal consistency reliability in both samples (Cronbach’s alphas > 0.86). Correlations with psychosocial measures were significant (p-values < .0001) and in the expected direction, offering evidence for convergent and concurrent validity. PROMIS Fatigue scores were significantly higher in patients who met case definition criteria for cancer-related fatigue (p < .0001), demonstrating criterion validity. Conclusion The current study provides evidence that the PROMIS Cancer Fatigue Short Form is a reliable and valid measure of fatigue in cancer patients.

The relationships of personal acculturation and of personal-family acculturation match to depressive symptoms were investigated in a sample of 68 Muslim university students. Two dimensions of personal and family acculturation were assessed: heritage and mainstream culture identification. Participants completed the Vancouver Index of Acculturation (Ryder, Alden, & Paulhus, 2000 ) and the depressive disorder subscale of the Psychiatric Diagnostic Screening Questionnaire (Zimmerman & Mattia, 1999 ). For personal acculturation, individuals with high personal heritage culture identification reported fewer lifetime (but not past-year) depressive symptoms. In contrast, individuals with high personal mainstream culture identification reported more past-year (but not lifetime) depressive symptoms. The hypothesis that a match between personal and family acculturation orientation would be associated with fewer depressive symptoms was supported for heritage culture identification only. For past-year depression, the two match conditions (low or high personal and family heritage culture identification) were associated with significantly fewer depressive symptoms than a low personal/high family mismatch but did not differ from a high personal/low family mismatch. For lifetime depression, a high personal/high family match was associated with significantly fewer depressive symptoms than all other conditions. Findings suggests that, for Muslims, a match of high personal and high family heritage culture identification may act as a protective factor for the experience of depressive symptoms both in the short term (past year) and in the long term (lifetime).

Patient-centered cancer care standards include routine psychosocial distress screening and referral for supportive care services. Although many cancer patients report psychosocial distress that could be alleviated by supportive services, including palliative care, patients often decline such services for reasons that are poorly understood. Research on decision-making suggests that, during periods of acute distress, individuals have more difficulty prioritizing long-term over immediate gains. Thus, distressed cancer patients may prioritize immediate gains (e.g., avoidance of palliative care discussions in the moment) over longer term gains (e.g., improved quality of life in the future). This study investigated the associations between psychosocial distress, difficulties with delay of gratification (tendency to prioritize short term over longer term gains), and preference for palliative care in a sample of 212 men with a history of prostate cancer (94% White, 27% advanced stage, age M = 62, SD = 8). It was hypothesized that psychosocial distress would be associated with lower preferences for palliative care, and this association would be explained, in part, by difficulty delaying gratification. Self-report measures included the Depression Anxiety Stress Scales, Delay of Gratification Inventory, and ratings on an item assessing preferences for palliative care. Consistent with the hypothesis, mediation models confirmed that the association of psychosocial distress with lower preference for palliative care was mediated by delay of gratification. Findings suggest that distressed prostate cancer patients may benefit from additional support managing the emotional aspects of medical decisions and weighing immediate vs. delayed outcomes.
