OBJECTIVE:: To determine changes in global gene expression in peripheral leukocytes in the acute and subacute periods following a sports-related concussion in athletes. SETTING:: Samples were collected at 2 universities in Rochester, New York. PARTICIPANTS:: Fifteen contact sport athletes who experienced a sports-related concussion, and 16 nonconcussed teammates served as controls. DESIGN:: Blood samples were collected at the start of the season (baseline), within 6 hours of injury (acute), and at 7 days (subacute) postinjury. Differential gene expression was measured using the GeneChip 3ʼ in vitro transcription Expression kit and Affymetrix microarrays, and genes with fold difference of 2 or more were identified using Partek. MAIN MEASURES:: Whole genome differential gene expression, and cognitive and balance measures to asses for clinical symptoms pre- and postinjury. RESULTS:: In the concussed athletes, we observed 67 downregulated and 4 upregulated genes in the acute period and 63 downregulated and 2 upregulated genes in the subacute period compared with baseline. Of these, there were 28 genes from both time points involved in the inflammatory response. No significant differences in gene expression were detected in the control group. CONCLUSIONS:: Our findings suggest that recovery from sports-related concussion relates to modulation of inflammation through cytokine and chemokine gene pathways, which can contribute to future development of personalized therapeutic agents.

OBJECTIVE:: To examine the utility of the Neurobehavioral Symptom Inventory (NSI)—a measure of postconcussion symptoms used within the Veterans Health Administration—as an index of rehabilitation outcome. SETTING:: Veterans Administration Polytrauma Rehabilitation Centers Traumatic Brain Injury (TBI) Model Systems program. PARTICIPANTS:: A total of 159 Veterans (14% with mild TBI; 86% with moderate-severe TBI). MAIN MEASURES:: Disability Rating Scale; Functional Independence Measure; Glasgow Outcome Scale–Extended; NSI; Participation Assessment with Recombined Tools–Objective; Posttraumatic Stress Disorder Checklist–Civilian Version; Satisfaction With Life Scale; Supervision Rating Scale. ANALYSES:: Correlations and exploratory factor analyses examined the interrelations among outcome measures. Hierarchical regression analyses were utilized to determine if the NSI predicted rehabilitation outcome measures after controlling for demographic variables, TBI severity, and time since injury. NSI reliable changes from pretreatment to 1-year follow-up were examined. Receiver operating characteristics curve analyses were conducted to evaluate the ability of changes in the NSI to predict meaningful change in functioning and employment status. RESULTS:: The NSI correlated with psychological distress measures. The NSI administered prior to brain injury rehabilitation had limited predictive utility beyond satisfaction with life. A minority of patients (32%) demonstrated reliable changes on the NSI from baseline to 1-year follow-up. Changes on the NSI were not predictive of meaningful change in employment or functioning. CONCLUSION:: The NSI was not useful for assessing meaningful change in a sample of mixed severity TBI patients. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved. Source

BACKGROUND:: In 2014, it is estimated that 232,670 new cases of breast cancer occurred in the United States. Unilateral or bilateral mastectomy is a frequently chosen option for treating this disease. OBJECTIVE:: The purpose of this study was to explore, through an in-depth interview process, the lived experience of women immediately following mastectomy when they see their scars for the first time. METHODS:: Purposeful sampling was used until saturation was reached. In-depth interviews were conducted with 10 women related to their mastectomy experience. The data were analyzed using a phenomenological approach. RESULTS:: The following 8 themes emerged from the data; lasting impact, personal impact, relational impact, gratitude, support system, coping strategies, timing, and discomfort. CONCLUSIONS:: The results of the study provide evidence that women face ongoing challenges following seeing their mastectomy scars for the first time that is not adequately addressed by healthcare professionals. IMPLICATIONS FOR PRACTICE:: Nurses and other healthcare professionals need to gain a better understanding of the difficulties perceived by women following seeing the scars from mastectomy and implement strategies to assist in successful adaptation to the experience.

BACKGROUND:: Fatigue is highly prevalent after hematopoietic stem cell transplantation (HCT). It has been described as intense and may last for years following treatment. OBJECTIVE:: The aim of this study is to compare fatigue, physical activity, sleep, emotional distress, cognitive function, and biological measures in HCT survivors with persistent fatigue (n = 25) with age- and gender-matched healthy controls with occasional tiredness (n = 25). METHODS:: Data were collected using (a) objective, real-time assessments of physical activity and sleep over 7 days; (b) patient-reported fatigue assessments; (c) computerized objective testing of cognitive functioning; and (d) biological measures. Differences between groups were examined using multivariate analysis of variance. RESULTS:: Survivors of HCT reported increased physical (P < .001), mental (P < .001), and overall (P < .001) fatigue as well as increased anxiety (P < .05) and depression (P < .01) compared with healthy controls. Red blood cell (RBC) levels were significantly lower in HCT survivors (P < .001). Levels of RBC for both groups, however, were in the normal range. Tumor necrosis factor-α (P < .001) and interleukin-6 (P < .05) levels were significantly higher in HCT survivors. CONCLUSIONS:: Persistent fatigue in HCT survivors compared with healthy controls with occasional tiredness is accompanied by increased anxiety and depression along with decreased RBC counts. Elevated tumor necrosis factor-α and interleukin-6 levels may be important biomarkers. IMPLICATIONS FOR PRACTICE:: This study provides preliminary support for the conceptualization of fatigue as existing on a continuum, with tiredness anchoring one end and exhaustion the other. Persistent fatigue experienced by HCT survivors is more severe than the occasional tiredness of everyday life. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved Source

BACKGROUND:: Although cancer in indigenous populations is receiving increased research attention, there is a gap in understanding the particular experiences of Aboriginal men. OBJECTIVE:: The aim of this study is to integrate a range of primary and secondary accounts of the experiences of Aboriginal men in engaging with a cancer diagnosis and treatment in Australia. METHODS:: Secondary analysis of qualitative interviews (n = 54) conducted between 2008 and 2011 revealed recurrent themes regarding the cancer experiences of Aboriginal men in a subset of participant interviews (n = 23). The analysis reports themes that spanned the accounts of Aboriginal men with cancer (n = 6) and those of their carers (n = 12) and clinicians (n = 5). RESULTS:: Recurrent beliefs about the cancer experiences of Aboriginal men included that they “avoid seeking help” for health matters, including cancer symptoms, and to “get on with it,” “not talk about it,” and “manage without fuss” after a cancer diagnosis. Although some men described having to “accept vulnerability,” emphasis was placed on appreciating men’s desire to “protect cultural roles” and “connect with family and culture” throughout care and treatment, including through humor. CONCLUSIONS:: Men’s accounts of the experiences of cancer diagnosis and care reveal more than simply individual challenge, extending to encompass the very real social and economic implications of illness and vulnerability for Aboriginal men today. IMPLICATIONS FOR PRACTICE:: Aboriginal men could be better engaged with cancer diagnosis and treatment if greater attention was paid to recognizing preferred approaches, including pragmatism and humor, and supporting connections to family and culture throughout the cancer journey.
