Abstract
Cachexia is a wasting condition associated with late stages of many chronic illnesses and may be present in up to 80% of patients with advanced cancers. Cachexia is a metabolic derangement resulting in a disturbance to the homeostasis of muscle breakdown and synthesis, favoring catabolism and muscle loss. Despite making strides in treating cancer itself, there have been no major advances in the treatment of cachexia pharmacologically or nutritionally. Clinical trials using anti-TNF biologics and thalidomide have largely failed. A new approach may be to focus on other possible waste-inducing mediators, possibly derived from mast cells, and the beneficial action of select natural flavonoids.

Abstract
BACKGROUND Increasing knowledge and understanding of disease is known to improve outcomes in persons living with a chronic illness. In this paper, we aim to compare the disease knowledge of children with sickle cell disease (SCD), age 6-10 years, who received an intervention (an educational colouring book on SCD) geared towards improving disease knowledge, to those who did not received the colouring book. METHODS A quasi-experimental study was conducted where disease knowledge was determined in 56 children who had received the colouring book and compared to 60 children who did not receive this intervention. RESULTS The mean knowledge score was significantly higher in the intervention group (mean difference = 2.65; 95% CI [1.43, 3.86]), as well as in older children and in those in higher grades but there was no difference between sexes. In a multiple regression model (adjusted R2 : 0.39; p value < .001), knowledge score was significantly higher in those who received the intervention (β: 2.62; 95% CI [1.48, 3.76]) while adjusting for age, gender, persons living at home, and the father's employment status. CONCLUSION The study highlights that a simple, inexpensive (cost: US$1/book) child-friendly intervention can significantly improve knowledge about SCD even in young children. It also underlines various social factors that are associated with children's understanding of their disease.

Abstract
Using an interdisciplinary research methodology across three archaeological and historical case studies, this article explores "family archives." Four themes illustrate how objects held in family archives, curation practices, and intergenerational narratives reinforce a family's sense of itself: people-object interactions, gender, socialization and identity formation, and the "life course." These themes provide a framework for professional archivists to assist communities and individuals working with their own family archives. We argue that the family archive, broadly defined, encourages a more egalitarian approach to history. We suggest a multiperiod analysis draws attention to historical forms of knowledge and meaning-making practices over time.

Abstract
BACKGROUND Past research on the association between insomnia and suicidal ideation (SI) has produced mixed findings. The current study explored the relationship between insomnia, SI, and past-year mental health status among a large Canadian Forces (CF) sample. METHOD Data was obtained from the 2013 Canadian Forces Mental Health Survey (CFMHS), and included a large representative sample of Canadian Regular Forces personnel (N = 6700). A series of univariate logistic regressions were conducted to test individual associations between past-year mental health status, insomnia, and potential confounds and SI. Mental health status included three groups: 0, 1, or two or more probable diagnoses of posttraumatic stress disorder (PTSD), major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder (PD) and alcohol abuse/dependence. Stepwise multivariate logistic regression was used to assess the relationship between insomnia and SI with mental health status as a moderator. RESULTS 40.8% of respondents reported experiencing insomnia. Both insomnia and number of mental health conditions incrementally increased the risk of SI. However, past-year mental health status was a significant moderator of this relationship, such that for CF personnel with either no (AOR = 1.61, 1.37-1.89) or only one past-year mental health condition (AOR = 1.39, 1.12-1.73), an incremental increase in insomnia was associated with an increased likelihood of SI. However, in personnel with two or more past-year mental health disorders, insomnia was no longer significantly associated with SI (AOR = 1.04, 0.81-1.33). CONCLUSIONS Insomnia significantly increased the odds of SI, but only among individuals with no or one mental health condition. Findings highlight the importance of assessing insomnia among CF members in order to further suicide prevention efforts.

Abstract
Dialysis providers in the United States may soon be held accountable for their patients' 30-day hospital readmissions. However, few studies have evaluated the timing of readmissions, which determines the window in which dialysis providers could act to prevent readmission. We therefore examined the timing of readmissions of hemodialysis patients in the United States and its association with mortality among 285,795 prevalent adult Medicare-primary hemodialysis patients from a national registry. Patients had at least one hospitalization in 2010-2013 (first index) and survived for 30 days or more. Readmission timing was defined as 0-7, 8-14, or 15-30 days after the index discharge. Multivariable Cox proportional hazards models were used to estimate the association between readmission timing (referent no readmission) and mortality, censored at one year. Overall, 23.1% of patients had readmissions within 30 days of the index discharge, of which over one-third (35.9%) were within the first week. Regardless of timing, patients with readmissions had a higher risk of death within one year, compared to those with no readmissions, with hazard ratios of 2.04 (95% confidence interval 2.00-2.09) for being readmitted within 15-30 days; 1.98 (1.93-2.04) for being readmitted within 8-14 days; and 1.76 (1.71-1.80) for being readmitted within 0-7 days. Thus, opportunities for dialysis providers to intervene and prevent early readmission may be limited. Regardless of the timing, readmission appears independently associated with a substantially increased risk of mortality in this population.

Abstract
Since the 1940s, men's presence at childbirth has changed from being out of the question to not only very common but often presented as highly valuable. This article examines this shift, charting how many men were present at their children's births over recent decades, considering how medical practitioners influenced men's participation, and analysing what meanings parents gave to this experience. It suggests a number of factors led to the relatively rapid move towards the acceptance of men's presence in the delivery room, but highlights this was not a simple transformation as a first glance at the figures would suggest. It argues that men's involvement in home births became more usual before hospitals changed their policies about men's presence, and considers how the role of fathers related to the increasingly medicalised nature of childbirth as this period progressed. It also considers whether men's involvement is always positive or welcome for those involved.

Abstract
Abstract
Intra-tumor heterogeneity drives neoplastic progression by supplying the fuel for natural selection among neoplastic cells. It also complicates screening and treatment of neoplasms. We hypothesize that the degree of intra-tumor heterogeneity in DCIS should predict which tumors are likely to become invasive and metastatic. We initiated a pilot project to test this hypothesis by comparing 9 cases of pure DCIS to 9 cases of DCIS with adjacent invasive disease. For each case, we sequenced the exome from two spatially distinct regions of DCIS as well as normal tissue taken from a lymph node with no tumor involvement. This required the development of new methods to extract high quality sequencing data from small amounts of DNA extracted from FFPE samples. We calculated the genetic divergence between the two tumor regions, defined as percent of the sequenced regions of the genome showing differences between the two samples that had sufficient sequencing coverage and quality scores for confident scoring. We also employed automated imaging analysis to score microenvironmental differences between the two tumor regions. These microenvironmental measures are based on ecological methods for measuring organismal interactions and habitats. We will present initial data on differences in phenotypic and genotypic intra-tumor heterogeneity comparing pure DCIS to DCIS associated with invasive breast cancer. Our methods can be readily translated to large tissue banks of FFPE samples from DCIS.

Abstract
In the southeastern US, substantial emissions of isoprene from deciduous trees undergo atmospheric oxidation to form secondary organic aerosol (SOA) that contributes to fine particulate matter (PM2.5). Laboratory studies have revealed that anthropogenic pollutants, such as sulfur dioxide (SO2), oxides of nitrogen (NO x ), and aerosol acidity, can enhance SOA formation from the hydroxyl radical (OH)-initiated oxidation of isoprene; however, the mechanisms by which specific pollutants enhance isoprene SOA in ambient PM2.5 remain unclear. As one aspect of an investigation to examine how anthropogenic pollutants influence isoprene-derived SOA formation, high-volume PM2.5 filter samples were collected at the Birmingham, Alabama (BHM), ground site during the 2013 Southern Oxidant and Aerosol Study (SOAS). Sample extracts were analyzed by gas chromatography-electron ionization-mass spectrometry (GC/EI-MS) with prior trimethylsilylation and ultra performance liquid chromatography coupled to electrospray ionization high-resolution quadrupole time-of-flight mass spectrometry (UPLC/ESI-HR-QTOFMS) to identify known isoprene SOA tracers. Tracers quantified using both surrogate and authentic standards were compared with collocated gas- and particle-phase data as well as meteorological data provided by the Southeastern Aerosol Research and Characterization (SEARCH) network to assess the impact of anthropogenic pollution on isoprene-derived SOA formation. Results of this study reveal that isoprene-derived SOA tracers contribute a substantial mass fraction of organic matter (OM) (~ 7 to ~ 20 %). Isoprene-derived SOA tracers correlated with sulfate ( SO42- ) (r2 = 0.34, n = 117) but not with NO x . Moderate correlations between methacrylic acid epoxide and hydroxymethyl-methyl-α-lactone (together abbreviated MAE/HMML)-derived SOA tracers with nitrate radical production (P[NO3]) (r2 = 0.57, n = 40) were observed during nighttime, suggesting a potential role of the NO3 radical in forming this SOA type. However, the nighttime correlation of these tracers with nitrogen dioxide (NO2) (r2 = 0.26, n = 40) was weaker. Ozone (O3) correlated strongly with MAE/HMML-derived tracers (r2 = 0.72, n = 30) and moderately with 2-methyltetrols (r2 = 0.34, n = 15) during daytime only, suggesting that a fraction of SOA formation could occur from isoprene ozonolysis in urban areas. No correlation was observed between aerosol pH and isoprene-derived SOA. Lack of correlation between aerosol acidity and isoprene-derived SOA is consistent with the observation that acidity is not a limiting factor for isoprene SOA formation at the BHM site as aerosols were acidic enough to promote multiphase chemistry of isoprene-derived epoxides throughout the duration of the study. All in all, these results confirm previous studies suggesting that anthropogenic pollutants enhance isoprene-derived SOA formation.

Abstract
Objectives Home telemental health services have the potential to overcome many individual and systemic barriers to care facing military veterans with posttraumatic stress disorder. However, little is known about the home telemental health-related attitudes and experiences of highly underserved rural or ethnically, racially diverse veterans. This study evaluated whether ethnically/racially diverse U.S. veterans residing in the rural Pacific Islands would find the delivery of evidence-based treatment for posttraumatic stress disorder via home telemental health tablet devices useful and helpful. Method Clinicians located in a central urban location delivered Cognitive Processing Therapy for posttraumatic stress disorder directly into patients' homes via a tablet device and secure WiFi connection. Pre- and post-treatment measures were collected from a clinical sample of 47 veterans (average age: 49.3 years). Most (74.4%) self-identified as being of ethnic/racial minority background. Attitudinal, satisfaction, and usability scales were collected from home telemental health engaging ( n = 29) and non-engaging ( n = 18) veterans. Results Ratings on measures of home telemental health comfort, satisfaction with care, and usability were uniformly positive. Veterans were equally open to receiving mental health services at home via home telemental health or in the clinic. In the case of services for a physical problem, however, veterans preferred in-clinic care. Following treatment, veterans' attitudinal scores increased on items such as "There is enough therapist contact in home telemental health interventions." However, a small portion of veterans (7%) reported having technical or privacy concerns. Conclusion The provision of evidence-based posttraumatic stress disorder treatment directly into the patients' homes proved feasible and was well received by the large majority of rural ethnically/racially diverse veterans.

Abstract
Background Vitamin D status generally varies seasonally with changing solar UVB radiation, time in the sun, amount of skin exposed, and, possibly, diet. The Seasonal D Study was designed to quantify the amplitude and phase of seasonal variation in the serum concentration of 25-hydroxyvitamin D, (25OH)D)) and identify the determinants of the amplitude and phase and those of inter-individual variability in seasonal pattern. Methods The Seasonal D Study collected data 2-monthly for 12 months, including demographics, personal sun exposure using a diary and polysulphone dosimeters over 7 days, and blood for serum 25(OH)D concentration. The study recruited 333 adults aged 18–79 years living in Canberra (35°S, n = 168) and Brisbane (27°South, n = 165), Australia. Discussion We report the study design and cohort description for the Seasonal D Study. The study has collected a wealth of data to examine inter- and intra-individual seasonal variation in vitamin D status and serum 25(OH)D levels in Australian adults.

Abstract
Objectives: The aim of this study was to evaluate the existing newborn sickle haemoglobinopathy screening programme in Jamaica. Methods: A retrospective analysis of infants screened during the period 8 November 1995 to 22 July 2006 was performed. Patient data for analyses was restricted to patients with homozygous (Hb SS) sickle cell disease. Published data from the Jamaican Sickle Cell Cohort Study was used to make comparisons with the study sample. Results: The study sample consisted of 435 patients with Hb SS disease. Acute chest syndrome was the most common clinical (non-death) event accounting for ∼50% of all events. Acute splenic sequestration, no longer a significant cause of mortality, was responsible for ∼32% of clinical events. Seven deaths (1.8%) occurred during the study period compared with 17.6% to the same age in the Jamaican Sickle Cell Cohort Study. There was a lower proportion of hospital admissions and episodes of serious illness in the study group compared with controls. Conclusions: Survival estimates for the study sample showed improvement compared with the Jamaican Sickle Cell Cohort Study. This study continues to demonstrate the benefits of, and as such shows support for, newborn screening and early interventions in sickle cell disease. In addition, it highlights some of the areas for continued focus and research development. Although the current system is providing an essential and beneficial service, the study emphasizes the need for newborn screening programmes to be comprehensive care systems to be fully effective.

Abstract
BACKGROUND Children's exposure to unhealthy food marketing is a contributor to poor diets and weight gain. Television food advertising, in particular, has been the focus of research and policy discussions. OBJECTIVES We aimed to quantify the specific impact of television advertising, as distinct from television viewing generally, on children's usual diet. Methods Four hundred seventeen Australian children aged 10-16 participated in an online survey, which assessed television viewing habits and consumption of 12 frequently advertised unhealthy foods/drinks. Consumption of these foods/drinks was dichotomized (less weekly, weekly or more) and summed (1 point for each item consumed weekly or more) to give cumulative consumption scores. RESULTS After adjusting for age and socioeconomic status, there was strong evidence of an increase in unhealthy food score (P < 0.001), drink score (P = 0.002) and food/drink combined score (P < 0.001), with increasing commercial television viewing. CONCLUSIONS The link between television viewing and poor diet was strongest for children who watched the most commercial television, and those who were actually exposed to advertisements embedded within programs. This association between advertisement exposure and poor diet emphasizes the need for public policy intervention to reduce children's food advertising exposures.

Abstract
BACKGROUND Psychosocial factors surrounding eating and drinking, such as enjoying food, managing restrictions, and maintaining social relationships, remain under-researched in inflammatory bowel disease [IBD]. This study aimed to develop and validate a food-related quality of life [FR-QoL] questionnaire to systematically measure these issues in the IBD population. METHODS Following semi-structured interviews with 28 IBD patients, 150 potential questionnaire items were generated. These were ranked by 100 IBD patients, and items were removed based on ceiling/floor effects and high inter-item correlations [> 0.7], with 41 items being retained. In total, 323 IBD patients, 100 asthma patients [chronic disease control], and 117 healthy controls completed the FR-QoL questionnaire, alongside generic and disease-specific QoL and food satisfaction questionnaires. Principal components analysis [PCA], construct and discriminant validity, and test-retest reliability were calculated. RESULTS Twelve items were removed following PCA. The reduced questionnaire [FR-QoL-29] explained 63.9% of the variance [Cronbach's α = 0.96]. FR-QoL-29 correlated significantly with generic QoL [r = 0.697], depression [r = -0.519], anxiety [r = -0.531], and food satisfaction [r = 0.701]. The FR-QoL-29 sumscores were significantly lower for IBD (89.5, standard deviation [SD] 28.6) than asthma [125.4, SD 24.1; p < 0.001] and healthy volunteers [123.0, SD 16.5; p<0.001]. Within IBD, worse food-related QoL was found in those with moderate/high disease activity [66.7, SD 22.1] compared with remission/low disease activity [92.5, SD 28.1]. Test-retest reliability was good (intra-class correlation [ICC] = 0.83, 95% confidence interval [CI] = 0.76:0.88). CONCLUSIONS The FR-QoL-29 shows good reliability and validity across a range of IBD characteristics. This easily administered questionnaire is a useful tool in identifying poor food-related QoL and in the future may identify areas for intervention.

Abstract
Background and Purpose Balance deficits in people with Parkinson’s disease can affect any of the multiple systems encompassing balance control. Thus, identification of the specific deficit is crucial in customizing balance rehabilitation. The sensory organization test, a test of sensory integration for balance control, is sometimes used in isolation to identify balance deficits in people with Parkinson’s disease. More recently, the Mini-Balance Evaluations Systems Test, a clinical scale that tests multiple domains of balance control, has begun to be used to assess balance in patients with Parkinson’s disease. The purpose of our study was to compare the use of Sensory Organization Test and Mini-Balance Evaluations Systems Test in identifying balance deficits in people with Parkinson’s disease. Methods 45 participants (27M, 18F; 65.2 ± 8.2 years) with idiopathic Parkinson’s disease participated in the cross-sectional study. Balance assessment was performed using the Sensory Organization Test and the Mini-Balance Evaluations Systems Test. People were classified into normal and abnormal balance based on the established cutoff scores (normal balance: Sensory Organization Test >69; Mini-Balance Evaluations Systems Test >73). Results More subjects were classified as having abnormal balance with the Mini-Balance Evaluations Systems Test (71% abnormal) than with the Sensory Organization Test (24% abnormal) in our cohort of people with Parkinson’s disease. There were no subjects with a normal Mini-Balance Evaluations Systems Test score but abnormal Sensory Organization Test score. In contrast, there were 21 subjects who had an abnormal Mini-Balance Evaluations Systems Test score but normal Sensory Organization Test scores. Discussion and Conclusions Findings from this study suggest that investigation of sensory integration deficits, alone, may not be able to identify all types of balance deficits found in patients with Parkinson’s disease. Thus, a comprehensive approach should be used to test of multiple balance systems to provide customized rehabilitation.

Abstract
Close peer networks can affect adolescents' health behaviors by altering their social environments, and thus their risk for and protection against substance use involvement. We tested a 20 minute intervention named Peer Network Counseling that integrates motivational interviewing and peer network strategies with 119 urban adolescents who reported occasional or problem substance use. Adolescents presenting at primary care clinic were randomized to intervention or control conditions and followed for 6 months. Mixed-effect latent growth models were used to evaluate intervention effects on trajectories of alcohol and marijuana use, offers to use substances, and moderation models to test for interactions between intervention condition and peer network characteristics. A significant intervention effect was found for boys for offers to use alcohol from friends (p<.05), along with a trend significant effect for alcohol use (p<.08). Intervention was more effective in reducing marijuana use, vs. control, for participants with more peer social support (p<.001) and with more peer encouragement for prosocial behavior (school, clubs, sports, religious activities); however, intervention did not affect these network characteristics. Results provide support to continue this line of research to test brief interventions that activate protective peer network characteristics among at-risk adolescents, while also raising some interesting gender-based intervention questions for future research.
