Abstract
OBJECTIVES To investigate the gut-brain axis, we explored the relationships among mood disturbance (MD), diet quality (DQ), and fecal microbiota in free-living adults. METHODS A cross-sectional analysis was conducted with data from 75 healthy adults enrolled in two studies. Anthropometrics, 16s rRNA gene sequencing of fecal microbes, DQ as assessed by Healthy Eating Index-2015 (HEI), and MD determined by Profile of Mood States (POMS) were included. Alpha-diversity and DQ differences were explored between low (n = 37) and high MD (n = 38) groups. Spearman correlations were used to investigate relationships between alpha-diversity, DQ, and POMS subscales. Moderation analysis explored the effect of HEI score on the relationship between MD and alpha-diversity. RESULTS Participants were mostly white (67%), 54.5 years old (±11.8), and overweight (28.5 ± 6.5 kg/m2). Shannon and Simpson indices indicate higher alpha-diversity in participants with low MD compared to high MD (p = 0.004 and p = 0.008, respectively). Simpson and Shannon indices were correlated with subscale of anger (rho = -0.303, p = 0.011; rho = -0.265, p = 0.027, respectively)and total MD (rho = -0.404, p = 0.001; rho = -0.357, p = 0.002, respectively). Refined grains were associated with fatigue and tension subscales (rho = 0.428, p < 0.001; rho = 0.302, p = 0.014, respectively). DQ did not significantly moderate the relationship between alpha-diversity and mood disturbance (F(7, 53) = 2.00, p = 0.072, R2 = 0.209). Shannon index was a significant predictor of MD (b = -4.39, t(53) = -2.55, p = 0.014), but total HEI score and the interaction (Shannon index*HEI score) were not significant. DISCUSSION Greater bacterial diversity was associated with lower MD, and DQ was associated with various mood state subscales in this sample of adults.

Abstract
A cross-sectional study was conducted to determine preventive-health-activity engagement in community-dwelling older adults participating in student-led health screenings in east Alabama. From 2017-2019, health professions students conducted health screenings at 23 community and independent living sites to assess medical and social needs of adults. Clients' responses to questions regarding vaccinations (flu/pneumonia/shingles), cancer screenings (colon/sex-specific), and other (dental/vision) screenings were aggregated to create a preventive health behavior (prevmed) score. Chi-square, t-tests, and regression analyses were conducted. Data from 464 adults ages 50-99 (72.9±10.1) years old were analyzed. The sample was 71.3% female, 63.1% Black/African American (BA), and 33.4% rural. Linear regression indicated BA race (p=0.001), currently unmarried (p=0.030), no primary care provider (p<0.001) or insurance (p=0.010), age <65 years (p=0.042) and assessment at a residential site (p=0.037) predicted lower prevmed scores. Social factors predict preventive health activity engagement in community-dwelling adults in east Alabama, indicating several opportunities to improve health outcomes.

Abstract
BACKGROUND The relationships between psychosocial stress and diet with gut microbiota composition and diversity deserve ongoing investigation. The primary aim of this study was to examine the associations of psychosocial stress measures and dietary variables with gut microbiota genera abundance and alpha diversity among young adult, black and white females. The secondary aim was to explore mediators of psychosocial stress and gut microbiota diversity and abundance. METHODS Data on 60 females who self-identified as African American (AA; n = 29) or European American (EA; n = 31) aged 21-45 years were included. Cortisol was measured in hair and saliva, and 16S analysis of stool samples were conducted. Discrimination experiences (recent and lifetime), perceived stress, and depression were evaluated based on validated instruments. Spearman correlations were performed to evaluate the influence of psychosocial stressors, cortisol measures, and dietary variables on gut microbiota genus abundance and alpha diversity measured by amplicon sequence variant (ASV) count. Mediation analyses assessed the role of select dietary variables and cortisol measures on the associations between psychosocial stress, Alistipes and Blautia abundance, and ASV count. RESULTS AA females were found to have significantly lower ASV count and Blautia abundance. Results for the spearman correlations assessing the influence of psychosocial stress and dietary variables on gut microbiota abundance and ASV count were varied. Finally, diet nor cortisol was found to partially or fully mediate the associations between subjective stress measures, ASV count, and Alistipes and Blautia abundance. CONCLUSION In this cross-sectional study, AA females had lower alpha diversity and Blautia abundance compared to EA females. Some psychosocial stressors and dietary variables were found to be correlated with ASV count and few gut microbiota genera. Larger scale studies are needed to explore the relationships among psychosocial stress, diet and the gut microbiome.

Abstract
INTRODUCTION Military veterans are at greater risk for chronic medical conditions, many of which are associated with greater body mass index (BMI). Detrimental changes to diet and physical activity (PA) levels after separation from military service contribute to this disparity which may be mitigated by nutrition education (NE) during service. METHODS We conducted a survey in student veterans attending two southeastern US universities to determine current nutrition knowledge and hypothesised that NE received during time of service would be associated with better current diet quality (DQ), PA and BMI. Food group knowledge (FGK), and nutrient knowledge, DQ measured by Healthy Eating Index (HEI), and PA reported in metabolic equivalent minutes per week (MET-min/week) were assessed using previously validated questionnaires. Height and weight were also self-reported to calculate BMI. Differences in these variables between NE groups were assessed using Mann-Whitney U tests. Change in DQ, PA and BMI were assessed with Wilcoxon signed rank tests. Stepwise backward regression analysis was used to identify significant predictors related to HEI and BMI status. RESULTS Sixty-three out of 83 total responses were valid. Respondents were 60% male, 81% white, 43% and 27% served in the Army and Navy, respectively and 30% reported receiving NE while in the military. Veterans who received NE while serving did not have higher FGK, nutrition knowledge, current DQ, MET-min/week or BMI than their counterparts. Overall, respondents reported decreased MET-min/week (p<0.001), increased BMI (p=0.01) and no change in DQ. PA (p=0.014) and FGK (p<0.001) were significant predictors of current DQ, while no variables significantly predicted current BMI. CONCLUSIONS Inverse relationships between BMI and PA were observed after separation from duty. These results warrant the development and implementation of effective lifestyle interventions in veterans to prevent chronic disease and improve quality of life.

Abstract
We examined how set-volume equated resistance training using either the back squat (SQ) or hip thrust (HT) affected hypertrophy and various strength outcomes. Untrained college-aged participants were randomized into HT (n = 18) or SQ (n = 16) groups. Surface electromyograms (sEMG) from the right gluteus maximus and medius muscles were obtained during the first training session. Participants completed 9 weeks of supervised training (15-17 sessions), before and after which gluteus and leg muscle cross-sectional area (mCSA) was assessed via magnetic resonance imaging. Strength was also assessed prior to and after the training intervention via three-repetition maximum (3RM) testing and an isometric wall push test. Gluteus mCSA increases were similar across both groups. Specifically, estimates [(-) favors HT (+) favors SQ] modestly favored the HT versus SQ for lower [effect ±SE, -1.6 ± 2.1 cm2; CI95% (-6.1, 2.0)], mid [-0.5 ± 1.7 cm2; CI95% (-4.0, 2.6)], and upper [-0.5 ± 2.6 cm2; CI95% (-5.8, 4.1)] gluteal mCSAs but with appreciable variance. Gluteus medius + minimus [-1.8 ± 1.5 cm2; CI95% (-4.6, 1.4)] and hamstrings [0.1 ± 0.6 cm2; CI95% (-0.9, 1.4)] mCSA demonstrated little to no growth with small differences between groups. mCSA changes were greater in SQ for the quadriceps [3.6 ± 1.5 cm2; CI95% (0.7, 6.4)] and adductors [2.5 ± 0.7 cm2; CI95% (1.2, 3.9)]. Squat 3RM increases favored SQ [14 ± 2 kg; CI95% (9, 18),] and hip thrust 3RM favored HT [-26 ± 5 kg; CI95% (-34, -16)]. 3RM deadlift [0 ± 2 kg; CI95% (-4, 3)] and wall push strength [-7 ± 12N; CI95% (-32, 17)] similarly improved. All measured gluteal sites showed greater mean sEMG amplitudes during the first bout hip thrust versus squat set, but this did not consistently predict gluteal hypertrophy outcomes. Squat and hip thrust training elicited similar gluteal hypertrophy, greater thigh hypertrophy in SQ, strength increases that favored exercise allocation, and similar deadlift and wall push strength increases.

Abstract
Head and neck cancer (HNC) is associated with high rates of malnutrition. We conducted a systematic review and descriptive analysis to determine the effects of nutrition interventions on the nutrition status, quality of life (QOL), and treatment tolerance of HNC patients. PubMed, Web of Science, and Embase were searched to include all potentially relevant studies published between 2006-2022. Meta-analysis was not conducted due to heterogeneity of study designs and outcomes reported. Studies were categorized as nutrition interventions: (1) with oral nutrition supplements (ONS) and medical nutrition therapy (MNT) delivered by an RD; (2) with enteral nutrition (EN) support and MNT delivered by an RD; (3) with motivational interviewing and no ONS or EN; and (4) with ONS and no RD. Seven articles met inclusion criteria. Studies measured outcomes from immediately following treatment to 12 months post-treatment. Interventions resulted in benefits to lean mass/weight maintenance (three studies), QOL (two studies), nutrient intake adequacy (one study) and treatment tolerance (two studies). Nutrition counseling by a registered dietitian leads to improved nutrition status and QOL. Further research is needed to determine best practices related to timing of initiation, duration of nutrition intervention, as well as frequency of dietitian follow-up.

Abstract
We sought to determine the skeletal muscle genome-wide DNA methylation and mRNA responses to one bout of lower load (LL) versus higher load (HL) resistance exercise. Trained college-aged males (n = 11, 23 ± 4 years old, 4 ± 3 years self-reported training) performed LL or HL bouts to failure separated by one week. The HL bout (i.e., 80 Fail) consisted of four sets of back squats and four sets of leg extensions to failure using 80% of participants estimated one-repetition maximum (i.e., est. 1-RM). The LL bout (i.e., 30 Fail) implemented the same paradigm with 30% of est. 1-RM. Vastus lateralis muscle biopsies were collected before, 3 h, and 6 h after each bout. Muscle DNA and RNA were batch-isolated and analyzed using the 850k Illumina MethylationEPIC array and Clariom S mRNA microarray, respectively. Performed repetitions were significantly greater during the 30 Fail versus 80 Fail (p < 0.001), although total training volume (sets × reps × load) was not significantly different between bouts (p = 0.571). Regardless of bout, more CpG site methylation changes were observed at 3 h versus 6 h post exercise (239,951 versus 12,419, respectively; p < 0.01), and nuclear global ten-eleven translocation (TET) activity, but not global DNA methyltransferase activity, increased 3 h and 6 h following exercise regardless of bout. The percentage of genes significantly altered at the mRNA level that demonstrated opposite DNA methylation patterns was greater 3 h versus 6 h following exercise (~75% versus ~15%, respectively). Moreover, high percentages of genes that were up- or downregulated 6 h following exercise also demonstrated significantly inversed DNA methylation patterns across one or more CpG sites 3 h following exercise (65% and 82%, respectively). While 30 Fail decreased DNA methylation across various promoter regions versus 80 Fail, transcriptome-wide mRNA and bioinformatics indicated that gene expression signatures were largely similar between bouts. Bioinformatics overlay of DNA methylation and mRNA expression data indicated that genes related to "Focal adhesion," "MAPK signaling," and "PI3K-Akt signaling" were significantly affected at the 3 h and 6 h time points, and again this was regardless of bout. In conclusion, extensive molecular profiling suggests that post-exercise alterations in the skeletal muscle DNA methylome and mRNA transcriptome elicited by LL and HL training bouts to failure are largely similar, and this could be related to equal volumes performed between bouts.

Abstract
PURPOSE To investigate relationships between body size, gut microbiome, and health-related quality of life (QOL) in breast cancer survivors (BCS) in a clinical trial. METHODS A cross-sectional substudy was conducted using baseline data from 70 BCS participating in a randomized controlled trial of a lifestyle intervention. Measures included anthropometrics, QOL (Short Form Health-related QOL Survey-36 [SF-36]), and 16S rRNA gene sequencing of fecal microbes. Participants were categorized by body mass index (BMI) into without obesity (≤ 29.9 kg/m2; n = 38) and with obesity (≥ 30.0 kg/m2; n = 32) groups. Differences in bacterial taxa between groups were assessed using Kruskal-Wallis one-way analysis of variance. Spearman and partial correlations explored associations between taxa and SF-36 subscales. Mediation analysis explored the relationship between BMI and SF-36 mental health summary score with alpha diversity as a mediator. RESULTS Most BCS (72.9%) were non-Hispanic White with average age of 61.6 (± 8.7) years. No differences were observed for SF-36 subscales between groups. Physical functioning, vitality, and mental health subscales were negatively associated with Ruminococcus (ρ = - 0.304, p = 0.036; ρ = - 0.361, p = 0.012; ρ = - 0.495, p < 0.001) and Dorea (ρ = - 0.378, p = 0.028; ρ = - 0.33, p = 0.022; ρ = - 0.388, p = 0.006) abundance controlling for BMI. BCS without obesity had a significantly higher relative abundance of Ruminococcus (p = 0.003), Streptococcus (p = 0.049), Roseburia (p = 0.035), and Dorea (p = 0.003). CONCLUSIONS Fecal microbial composition differed between BCS with and without obesity, with associations between QOL and several microbial taxa. Several of these genera, previously identified as potentially beneficial, may also influence QOL in BCS. These results support further studies to determine the role of individual microbiota in QOL and obesity in cancer survivors.

Abstract
BACKGROUND Interprofessional education is imperative for training future healthcare professionals. While barriers exist within and across institutions to implement and sustain effective interprofessional education experiences for students, virtual clinics utilizing electronic health records may provide comparable benefits to in-person clinics. OBJECTIVE To determine whether differences in pre- and post-test self-assessments of interprofessional collaborative competencies are different between in-person and virtual clinics. DESIGN Pretest-posttest design utilizing the Interprofessional Collaborative Competencies Attainment Survey (ICCAS) before and immediately after participating in clinics, virtual or in-person. SETTING A large, public university in the southeastern United States. PARTICIPANTS Senior nursing students, third-year pharmacy students, senior nutrition/dietetics students, and undergraduate and graduate social work students. METHODS This study was conducted evaluating five cohorts of students engaged in interprofessional education clinics. Two cohorts completed in-person community clinics in 2019. In March 2020, the interprofessional education program adopted virtual clinics (three cohorts) utilizing pre-selected electronic health record cases. Student responses from the 20-item ICCAS, which was completed before and immediately after clinics, were aggregated into interprofessional competency subscale scores (communication, collaboration, roles and responsibilities, collaborative patient/family-centered approach, conflict management/resolution, and team functioning) and a total ICCAS score. Two-way ANOVA assessed Pre-Post and Mode (in-person vs. virtual) on total ICCAS score. t-tests compared Pre-Post ICCAS scores for each Mode. RESULTS Effects of Pre-Post (p < 0.001), but not Mode (p = 0.523), were observed on Total ICCAS scores. All ICCAS subscale scores were significantly higher in Post compared to Pre regardless of Mode. CONCLUSIONS Virtual interprofessional education clinics confer similar benefits to interprofessional collaborative competencies in healthcare professions students compared to in-person community clinics. Thus, modality offers flexibility for interprofessional education and provided several benefits over the in-person clinic approach.

Abstract
BACKGROUND Accelerated functional decline is a concern among older cancer survivors that threatens independence and quality of life. Pilot studies suggest that vegetable gardening interventions ameliorate functional decline through improved diet and physical activity. OBJECTIVE The aim of this article was to describe the rationale, recruitment challenges, and enrollment for the Harvest for Health randomized controlled trial (RCT), which will test the impact of a home-based, vegetable gardening intervention on vegetable and fruit consumption, physical activity, and physical functioning among older cancer survivors. Modifications made to the intervention and assessments to assure safety and continuity of the RCT throughout the COVID-19 pandemic also are reported. DESIGN Harvest for Health is a 2-year, 2-arm, single-blinded, wait-list controlled RCT with cross-over. PARTICIPANTS/SETTING Medicare-eligible survivors of cancers with ≥60% 5-year survival were recruited across Alabama from October 1, 2016 to February 8, 2021. INTERVENTION Participants were randomly assigned to a wait-list control or a 1-year home-based gardening intervention and individually mentored by extension-certified master gardeners to cultivate spring, summer, and fall vegetable gardens. MAIN OUTCOME MEASURES Although the RCT's primary end point was a composite measure of vegetable and fruit consumption, physical activity, and physical functioning, this article focuses on recruitment and modifications made to the intervention and assessments during COVID-19. STATISTICAL ANALYSES PERFORMED χ2 and t tests (α < .05) were used to compare enrolled vs unenrolled populations. RESULTS Older cancer survivors (n = 9,708) were contacted via mail and telephone; 1,460 indicated interest (15% response rate), 473 were screened eligible and consented, and 381 completed baseline assessments and were randomized. Enrollees did not differ from nonrespondents/refusals by race and ethnicity, or rural-urban status, but comprised significantly higher numbers of comparatively younger survivors, those who were female, and survivors of breast cancer (P < .001). Although COVID-19 delayed trial completion, protocol modifications overcame this barrier and study completion is anticipated by June 2022. CONCLUSIONS This RCT will provide evidence on the effects of a mentored vegetable gardening program among older cancer survivors. If efficacious, Harvest for Health represents a novel, multifaceted approach to improve lifestyle behaviors and health outcomes among cancer survivors-one with capacity for sustainability and widespread dissemination.

Abstract
Background Colorectal cancer in adults 50 years old and younger is increasing in incidence worldwide. Diet may be a modifiable risk factor. The objective of this study was to examine evidence regarding the association between diet and the risk of developing early-onset colorectal cancer (EOCRC) and early-onset colorectal adenomas in young adults. Methods PUBMED, Web of Science, and Embase were systematically searched for studies examining dietary intake as a risk factor for EOCRC and early-onset colorectal adenomas. Results were synthesized narratively due to the heterogeneity of the studies. Results Of the 415 studies identified, ten met the inclusion criteria. Of these ten studies, four provided data on dietary risk factors for early-onset colorectal adenomas and six provided data on dietary risk factors for EOCRC. The four studies that measured colorectal adenoma occurrence reported an increased incidence with high sugar sweetened beverage intake, a higher pro-inflammatory diet, a higher Western diet score and higher sulfur microbial diet score. A protective effect against early-onset colorectal adenomas was observed in those who had a higher Prudent diet score or higher adherence to other health dietary approaches (Dietary Approaches to Stop Hypertension, Alternative Healthy Eating Index-2010, or the alternative Mediterranean diet). Those who consumed large amounts of deep-fried foods, refined foods, followed a high fat diet, consumed large amounts of sugary drinks and desserts, and had low folate and fiber consumption had a significantly higher occurrence of EOCRC. A protective effect against EOCRC was observed for those who consumed more fruits and vegetables, high amounts of micronutrients and those who adhered to a vegetarian diet. Conclusions The results of this study reveal various dietary habits may be risk factors or protective against early-onset colorectal cancer and adenomas. Future research should focus on large prospective cohort studies with long-term follow-up to confirm published results and further examine whether differences in diet quality are associated with EOCRC risk.

Abstract
The bacteria inhabiting the gastrointestinal tract contribute to numerous host functions and can be altered by lifestyle factors. We aimed to determine whether a 6-week training intervention altered fecal microbiome diversity and/or function in older males. Fecal samples were collected prior to and following a 6-week twice-weekly supervised resistance training intervention in 14 older Caucasian males (65 ± 10 years, 28.5 ± 3.2 kg/m2) with minimal prior training experience. Participants were randomized to receive a daily defatted peanut powder supplement providing 30 g protein (n = 8) or no supplement (n = 6) during the intervention. Bacterial DNA was isolated from pre-and post-training fecal samples, and taxa were identified using sequencing to amplify the variable region 4 (V4) of the 16S ribosomal RNA gene. Training significantly increased whole-body and lower-body lean mass (determined by dual energy X-ray absorptiometry) as well as leg extensor strength (p < 0.05) with no differences between intervention groups. Overall composition of the microbiome and a priori selected taxa were not significantly altered with training. However, MetaCYC pathway analysis indicated that metabolic capacity of the microbiome to produce mucin increased (p = 0.047); the tight junction protein, zonulin, was measured in serum and non-significantly decreased after training (p = 0.062). Our data suggest that resistance training may improve intestinal barrier integrity in older Caucasian males; further investigation is warranted.

Abstract
Protein supplementation is a commonly employed strategy to enhance resistance training adaptations. However, little research to date has examined if peanut protein supplementation is effective in this regard. Thus, we sought to determine if peanut protein supplementation (PP; 75 total g/d of powder providing 30 g/d protein, >9.2 g/d essential amino acids, ~315 kcal/d) affected resistance training adaptations in college-aged adults. Forty-seven college-aged adults (n = 34 females, n = 13 males) with minimal prior training experience were randomly assigned to a PP group (n = 18 females, n = 5 males) or a non-supplement group (CTL; n = 16 females, n = 8 males) (ClinicalTrials.gov trial registration NCT04707963; registered 13 January 2021). Body composition and strength variables were obtained prior to the intervention (PRE). Participants then completed 10 weeks of full-body resistance training (twice weekly) and PP participants consumed their supplement daily. POST measures were obtained 72 h following the last training bout and were identical to PRE testing measures. Muscle biopsies were also obtained at PRE, 24 h following the first exercise bout, and at POST. The first two biopsy time points were used to determine myofibrillar protein synthesis (MyoPS) rates in response to a naïve training bout with or without PP, and the PRE and POST biopsies were used to determine muscle fiber adaptations in females only. Dependent variables were analyzed in males and females separately using two-way (supplement × time) repeated measures ANOVAs, unless otherwise stated. The 24-h integrated MyoPS response to the first naïve training bout was similar between PP and CTL participants (dependent samples t-test p = 0.759 for females, p = 0.912 for males). For males, the only significant supplement × time interactions were for DXA-derived fat mass (interaction p = 0.034) and knee extensor peak torque (interaction p = 0.010); these variables significantly increased in the CTL group (p < 0.05), but not the PP group. For females, no significant supplement × time interactions existed, although interactions for whole body lean tissue mass (p = 0.088) and vastus lateralis thickness (p = 0.099) approached significance and magnitude increases in these characteristics favored the PP versus CTL group. In summary, this is the second study to determine the effects of PP supplementation on resistance training adaptations. While PP supplementation did not significantly enhance training adaptations, the aforementioned trends in females, the limited n-size in males, and this being the second PP supplementation study warrant more research to determine if different PP dosing strategies are more effective than the current approach.

Abstract
Resistance training (RT) dynamically alters the skeletal muscle nuclear DNA methylome. However, no study has examined if RT affects the mitochondrial DNA (mtDNA) methylome. Herein, ten older, Caucasian untrained males (65 ± 7 y.o.) performed six weeks of full-body RT (twice weekly). Body composition and knee extensor torque were assessed prior to and 72 h following the last RT session. Vastus lateralis (VL) biopsies were also obtained. VL DNA was subjected to reduced representation bisulfite sequencing providing excellent coverage across the ~16-kilobase mtDNA methylome (254 CpG sites). Biochemical assays were also performed, and older male data were compared to younger trained males (22 ± 2 y.o., n = 7, n = 6 Caucasian & n = 1 African American). RT increased whole-body lean tissue mass (p = .017), VL thickness (p = .012), and knee extensor torque (p = .029) in older males. RT also affected the mtDNA methylome, as 63% (159/254) of the CpG sites demonstrated reduced methylation (p < .05). Several mtDNA sites presented a more "youthful" signature in older males after RT in comparison to younger males. The 1.12 kilobase mtDNA D-loop/control region, which regulates replication and transcription, possessed enriched hypomethylation in older males following RT. Enhanced expression of mitochondrial H- and L-strand genes and complex III/IV protein levels were also observed (p < .05). While limited to a shorter-term intervention, this is the first evidence showing that RT alters the mtDNA methylome in skeletal muscle. Observed methylome alterations may enhance mitochondrial transcription, and RT evokes mitochondrial methylome profiles to mimic younger men. The significance of these findings relative to broader RT-induced epigenetic changes needs to be elucidated.

Abstract
Green leafy vegetables (GLV) may reduce the risk of red meat (RM)-induced colonic DNA damage and colorectal cancer (CRC). We previously reported the primary outcomes (feasibility) of a 12-week randomized controlled crossover trial in adults with habitual high RM and low GLV intake with body mass index (BMI) > 30 kg/m2 (NCT03582306). Herein, our objective was to report a priori secondary outcomes. Participants were recruited and enrolled in 2018, stratified by gender, and randomized to two arms: immediate intervention group (IG, n = 26) or delayed intervention group (DG, n = 24). During the 4 week intervention period, participants were provided with frozen GLV and counseled to consume 1 cooked cup equivalent daily. Participants consumed their normal diet for the remaining 8 weeks. At each of four study visits, anthropometrics, stool, and blood were taken. Overall, plasma Vitamin K1 (0.50 ± 1.18 ng/mL, p < 0.001) increased, while circulating 8OHdG (−8.52 ± 19.05 ng/mL, p < 0.001), fecal 8OHdG (−6.78 ± 34.86 ng/mL, p < 0.001), and TNFα (−16.95 ± 60.82 pg/mL, p < 0.001) decreased during the GLV intervention compared to control periods. Alpha diversity of fecal microbiota and relative abundance of major taxa did not differ systematically across study periods. Further investigation of the effects of increased GLV intake on CRC risk is warranted.

Abstract
Implicated in several chronic diseases, the gastrointestinal microbiome is hypothesised to influence carcinogenesis. We compared faecal microbiota of newly diagnosed treatment-naïve overweight and obese cancer patients and matched controls. Cases were enrolled in presurgical weight-loss trials for breast (NCT02224807) and prostate (NCT01886677) cancers and had a body mass index (BMI) ≥25 kg/m2. Cancer-free controls were matched 1:1 by age (±5 years), race, gender, and BMI (±5 kg/m2). All participants provided faecal samples; isolated bacterial DNA were PCR amplified at the V4 region of the 16S rRNA gene and analysed using the QIIME pipeline. Tests compared cases versus controls, then separately by gender. Microbial alpha-diversity and beta-diversity were assessed, and relative abundance of Operational Taxonomic Units (OTU's) were compared at the genus level, with false discovery rate (FDR) correction. 22 overweight and obese cancer patients were matched with 22 cancer-free controls, with an average BMI of 30.5±4.3 kg/m2, age 54.4±5.3 years, and 54.5% were black. Fourteen matches were made between breast cancer cases and healthy female controls, and 8 matches were made with prostate cancer cases and healthy male controls. Comparison of all cases and controls revealed no differences in alpha diversity, though prostate cancer patients had higher Chao1 (P=0.006) and Observed Species (P=0.036) than cancer-free males. Beta-diversity metrics were significantly different between cases and controls (P<0.03 for all tests in whole sample and in men), though only unweighted Unifrac was different in women (P=0.005). Kruskal Wallis tests indicated significant differences among 16 genera in all matches, 9 in female, and 51 in male. This study suggests the faecal microbiota of treatment-naive breast and prostate cancer patients differs from controls, though larger samples are needed to substantiate these findings.

Abstract
In December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) emerged in Wuhan, China, sparking the Coronavirus disease 2019 (COVID-19) pandemic. The high prevalence of nutrition-related COVID-19 risk factors including obesity, type 2 diabetes, and hypertension, suggests that healthy dietary approaches may mitigate COVID-19 related outcomes and possibly SARS-CoV-2 infection. Based on the fundamental role of nutrition in immune function and the well-documented association between Mediterranean diet consumption and risk reduction for chronic diseases that are comorbidities in COVID-19 patients, we hypothesized that there would be a relationship between Mediterranean diet adherence and COVID-19 cases and related deaths. In this perspective, we examined the association between regional adherence to a Mediterranean diet and COVID-19 cases and deaths using an ecological study design. We observed that Mediterranean diet adherence was negatively associated with both COVID-19 cases and related deaths across 17 regions in Spain and that the relationship remained when adjusted for factors of well-being. We also observed a negative association between Mediterranean diet adherence and COVID-19 related deaths across 23 countries when adjusted for factors of well-being and physical inactivity. The anti-inflammatory properties of the Mediterranean diet - likely due to the polyphenol content of the diet - may be a biological basis to explain our findings. However, there are confounding factors unrelated to dietary factors driving COVID-19 cases and related deaths across the regions in Spain and the 23 countries examined in our analysis. Our findings will need to be confirmed and further explored in cohort studies.

Abstract
Background: Colon cancer (CC) risk is increased by behavioral factors including a diet high in red meat (RM) and processed meat; excess adiposity has contributed to a rise in CC in younger adults. The willingness of at-risk adults to modify behaviors to reduce CC risk warrants further investigation. Methods: The previously validated Dietary Habits and Colon Cancer Beliefs Survey (DHCCBS) was used to assess attitudes and beliefs related to CC risk and diet behavior. An abbreviated food frequency questionnaire was included in the survey to quantify RM and green leafy vegetable (GLV) intake over the previous 30 days. Independent samples t-tests compared RM and GLV intake and DHCCBS responses. One-way analysis of variance with post-hoc LSD correction was completed to assess these differences within three age groups (<35, 35–44, and 45–54 years old) and between U.S. Census Bureau geographical regions. Results: Eight hundred and thirty eight survey responses were analyzed. Perceived severity of CC diagnosis was significantly lower in younger adults (<35) compared to older adults (35–44, p = 0.042; 45–54, p = 0.003). Furthermore, younger adults (<35) perceived fewer barriers (i.e., taste preference) to GLV consumption than their older adult counterparts (35–44, p = 0.019; 45–54, p = 0.002). Few regional differences in habitual RM consumption were observed, however, several disparities were observed with GLV. Conclusion: These findings from the DHCCBS indicate health beliefs toward CC risk are influenced by an individual's age and dietary habits. Additionally, regional differences in GLV consumption indicate opportunities for risk-reduction-focused health messages, particularly in the southern United States where CC incidence and mortality are highest.

Abstract
Our previous presurgical weight loss trial among 40 prostate cancer patients found that rapid (but not slow) weight loss resulted in increased tumor Ki67 and Cathepsin L (CTSL) gene expression. In follow-up analyses, we strove to better understand these unexpected findings. A correlative study was undertaken by performing additional analyses [free fatty acids (FFAs), plasma CTSL, and inflammatory cytokines] on remaining pre-post intervention sera and exploring associations with extant data on tumor Ki67, body composition, physical activity (PA), and fecal microbiota. Positive associations were observed between changes in % body fat and FFAs (ρ = 0.428, p = 0.026), insulin (ρ = 0.432, p = 0.019), and Interleukin-6 (ρ = 0.411, p = 0.041). Change in Ki67 was inversely associated with change in lean mass (ρ = -0.912, p = 0.001) and change in insulin (ρ = -0.650, p = 0.042). Change in insulin was also associated with CTSL (ρ = -0.643, p = 0.024) and FFAs (ρ = -0.700, p = 0.016). Relative abundance of Bifidobacterium was associated with CTSL (ρ = 0.627, p = 0.039) and FFAs (ρ = 0.691, p = 0.019); Firmicutes was positively associated with change in PA (ρ = 0.830, p = 0.003). Contrary to hypotheses, FFAs decreased with systemic fat loss. Moreover, although glucose metabolism improved, it was inversely associated with Ki67 and CTSL. Lean mass loss was highly correlated with increased Ki67. The relationships between prostate tumor Ki67 and CTSL and weight loss associated changes in FFAs, lean mass, and fecal microbiota warrant further investigation.

Abstract
Breast cancer is a hormonally-driven cancer, and various dietary factors are associated with estrogen metabolism, including dietary fiber. Several studies report associations between dietary fiber and breast cancer; however, research on whether fiber influences circulating estrogens through the gut microbiota is rare. The objective of this cross-sectional study among 29 newly-diagnosed (stage 0-II), post-menopausal breast cancer patients is to examine associations between dietary fiber and the gut microbiota that are linked with β-glucuronidase activity, and purportedly increase circulating estrogens. Spearman's and partial correlations controlling for body mass index and age were performed using dietary recall data, Illumina MiSeq generated microbiota relative abundance, and HPLC-mass spectrometry-derived estradiol and estrone levels.Major findings are: (1) total dietary fiber is inversely associated with Clostridium hathewayi (r= -0.419; p = 0.024); (2) soluble fiber is inversely associated with Clostridium (r=-0.11; p = 0.02); (3) insoluble fiber is positively associated with Bacteroides uniformis sp. (r = 0.382; p = 0.041); and (4) serum estradiol and estrone levels are not correlated with species/genera or dietary fiber, though there is a trend toward an inverse association between soluble fiber and estradiol levels (r= -0.30; p = 0.12). More studies are needed to understand the complex interaction between dietary fiber, intestinal microbiota, and hormonal levels in older females.

Abstract
Objective: Altering the gut microflora may produce health benefits in individuals suffering from mood disorders. The purpose of this review was to evaluate the efficacy of probiotics, prebiotics, or synbiotics as a potential treatment for symptoms of depression, anxiety, and stress (as psychobiotics).Methods: Google Scholar, PubMed, PsychINFO, and Web of Science were utilized to identify and evaluate studies through October 31, 2019. Studies were included if subjects were evaluated for altered mood or stress levels at start of the study and consumed probiotics, prebiotics, and/or synbiotics for intervention.Results: Search results yielded 142 articles, while only 12 studies met all inclusion criteria. Nine of the 12 studies identified evaluated the efficacy of various probiotic strains, while only two evaluated synbiotics and one evaluated prebiotics. Six out of 12 studies found probiotics to reduce depression, while two studies found probiotics to reduce anxiety.Discussion: Translational research in this field is limited and further investigation of the efficacy of psychobiotics in mood disorders is warranted.

Abstract
BACKGROUND Dietary preferences vary depending on cancer type. The purpose of this study was to report dietary intervention preferences and a study program evaluation from post-treatment head and neck cancer survivors participating in a dietary intervention. METHODS Between January 2015 and August 2016, 24 head and neck cancer survivors participated in a 12-week randomized clinical dietary intervention trial that promoted weekly consumption of 2.5 cups of cruciferous vegetables and 3.5 cups of green leafy vegetables. At study completion, survivors completed a preferences survey and a study program evaluation to probe interests and improvement aspects for planning future dietary intervention trials. Descriptive statistics (means and frequencies) were generated for multiple choice question responses. Responses to open-ended questions were recorded and grouped based on themes, and verified by quality assurance checks by a second study team member. RESULTS Twenty-three survivors completed the preferences and evaluation surveys (response rate 96%). Overall, most participants reported a preference for one-on-one telephone counseling from a registered dietitian nutritionist before beginning treatment. Ninety-six percent of participants ranked the overall study program as "very good" to "excellent," and all agreed the objectives of the study were clear, the study staff was helpful and easy to contact, and the registered dietitian nutritionist was knowledgeable. CONCLUSIONS Future research and dietary intervention planning for head and neck cancer survivors should focus on strategies to promote one-on-one telephone or other distance-based counseling combined with face-to-face visits, according to survivor preference.

Abstract
Obesity adversely impacts overall and cancer‐specific survival among breast cancer patients. Preclinical studies demonstrate negative energy balance inhibits cancer progression; however, feasibility and effects in patients are unknown. A two‐arm, single‐blinded, randomized controlled weight‐loss trial was undertaken presurgery among 32 overweight/obese, Stage 0–II breast cancer patients. The attention control arm (AC) received basic nutritional counseling and upper‐body progressive resistance training whereas the weight loss intervention (WLI) arm received identical guidance, plus counseling on caloric restriction and aerobic exercise to promote 0.68–0.92 kg/week weight loss. Anthropometrics, body composition, blood and survey data were collected at baseline and presurgery ∼30 days later. Tumor markers (e.g., Ki67) and gene expression were assessed on biopsy and surgical specimens; sera were analyzed for cytokines, growth and metabolic factors. Significant WLI vs. AC differences were seen in baseline‐to‐follow‐up changes in weight (−3.62 vs. −0.52 kg), %body fat (−1.3 vs. 0%), moderate‐to‐vigorous physical activity (+224 vs. +115 min/week), caloric density (−0.3 vs. 0 kcal/g), serum leptin (−12.3 vs. −4.0 ng/dl) and upregulation of tumor PI3Kinase signaling and cell cycle‐apoptosis related genes (CC‐ARG; all p‐values <0.05). Cytolytic CD56dimNK cell expression was positively associated with weight loss; CC‐ARG increased with physical activity. Increased tumor (nuclear) TNFα and IL‐1β, CX3CL1 and CXCL1 gene expression was observed in the WLI. Tumor Ki67 did not differ between arms. Feasibility benchmarks included 80% accrual, 100% retention, no adverse effects and excellent adherence. Short‐term weight loss interventions are feasible; however, mixed effects on tumor biology suggest unclear benefit to presurgical caloric restriction, but possible benefits of physical activity. What's new? Obesity adversely impacts survival among breast cancer patients. Preclinical studies demonstrate negative energy balance inhibits cancer progression; however, effects in patients are unknown. This is the first randomized controlled trial to assess the impact of a pre‐surgical weight loss intervention among early‐stage breast cancer patients. Results show the effects of acute negative energy balance on tumor biology, circulating biomarkers, and quality‐of‐life. Short‐term weight loss interventions are feasible; however, mixed effects on tumor biology suggest unclear benefit to pre‐surgical caloric restriction. Such interventions may be better timed after surgical resection, though cell cycle‐apoptosis and DNA damage‐repair scores support increasing physical activity.

Abstract
The Mediterranean diet (MedDiet) is recommended by the current Dietary Guidelines for Americans, yet little is known about the perceived barriers and benefits to the diet in the U.S., particularly in the Stroke Belt (SB). Thus, the purpose of this study was to examine MedDiet adherence and perceived knowledge, benefits, and barriers to the MedDiet in the U.S. A cross-sectional study was conducted on 1447 participants in the U.S., and responses were sorted into geographic groups: the SB, California (CA), and all other US states (OtherUS). Linear models and multivariable linear regression analysis was used for data analysis. Convenience, sensory factors, and health were greater barriers to the MedDiet in the SB group, but not the OtherUS group (p < 0.05). Weight loss was considered a benefit of the MedDiet in the SB (p < 0.05), while price and familiarity were found to be less of a benefit (p < 0.05). Respondents with a bachelor’s degree or greater education had greater total MEDAS scores (p < 0.05) and obese participants had a lower MedDiet adherence score (p < 0.05). Our results identify key barriers and benefits of the MedDiet in the SB which can inform targeted MedDiet intervention studies.

Abstract
BACKGROUND Adequate dietary intake is important for promoting adaptation and prevention of musculoskeletal injury in response to large volumes of physical training such as Army Initial Entry Training (IET). The purpose of this study was to evaluate training volume and dietary intake and estimate energy balance in Army IET soldiers. METHODS Dietary intake was assessed by collecting diet logs for three meals on each of three, non-consecutive days during the first week of IET. Training volume was measured across 13 weeks of training using Actigraph wGT3X accelerometers. Training intensity was classified using Sasaki vector magnitude three cut points. Energy expenditure estimates were calculated during weeks two and three of training using the modified Harris-Benedict equation and by estimation of active energy expenditure using metabolic equivalents for each classification of physical activity. All data is presented as mean ± standard deviation. RESULTS A total of 111 male soldiers (ht. = ± 173 ± 5.8 cm, age = 19 ± 2 years, mass = 71.6. ± 12.4 kg) completed diet logs and were monitored with Actigraphs. IET soldiers performed on average 273 ± 62 min low, 107 ± 42 min moderate, 26 ± 22 min vigorous, and 10 ± 21 min of very vigorous intensity physical activity daily across 13 weeks. The estimated total daily energy expenditure was on average 3238 ± 457 kcals/d during weeks two and three of IET. Compared to week one caloric intake, there was a caloric deficit of 595 ± 896 kcals/d on average during weeks two and three of IET. Regression analysis showed that body weight was a significant predictor for negative energy balance (adj. R2 = 0.54, p < 0.001), whereby a 1 kg increase in body mass was associated with a 53 kcal energy deficit. CONCLUSIONS Based on week one dietary assessment, IET soldiers did not consume adequate calories and nutrients to meet training needs during red phase (weeks one through three). This may directly affect soldier performance and injury frequency. IET soldiers undergo rigorous training, and these data may help direct future guidelines for adequate nourishment to optimize soldier health and performance.

Abstract
BACKGROUND Akkermansia muciniphila (AM) is a gram-negative, mucin-degrading bacteria inhabiting the gastrointestinal tract associated with host phenotypes and disease states. OBJECTIVE Explore characteristics of overweight and obese female early-stage (0 to II) breast cancer patients with low AM relative abundance (LAM) vs high (HAM) enrolled in a presurgical weight-loss trial. DESIGN Secondary analysis of pooled participants in a randomized controlled trial (NCT02224807). PARTICIPANTS/SETTING During the period from 2014 to 2017, 32 female patients with breast cancer were randomized to weight-loss or attention-control arms from time of diagnosis-to-lumpectomy (mean=30±9 days). INTERVENTION All were instructed to correct nutrient deficiencies via food sources and on upper-body exercises. The weight-loss group received additional guidance to promote 0.5 to 1 kg/wk weight-loss via energy restriction and aerobic exercise. MAIN OUTCOME MEASURES At baseline and follow-up, sera, fecal samples, two-24 hour dietary recalls and dual x-ray absorptiometry were obtained. Bacterial DNA was isolated from feces and polymerase chain reaction (16S) amplified. Inflammatory cytokines were measured in sera. STATISTICAL ANALYSES PERFORMED Differences between LAM and HAM participants were analyzed using t tests and nonparametric tests. Spearman correlations explored relationships between continuous variables. RESULTS Participants were aged 61±9 years with body mass index 34.8±6. Mean AM relative abundance was 0.02% (0.007% to 0.06%) and 1.59% (0.59% to 13.57%) for LAM and HAM participants, respectively. At baseline, women with HAM vs LAM had lower fat mass (38.9±11.2 kg vs 46.4±9.0 kg; P=0.044). Alpha diversity (ie, species richness) was higher in women with HAM (360.8±84.8 vs 282.4±69.6; P=0.008) at baseline, but attenuated after weight-loss (P=0.058). At baseline, interleukin-6 level was associated with species richness (ρ=-0.471, P=0.008) and fat mass (ρ=0.529, P=0.002), but not AM. Change in total dietary fiber was positively associated with AM in LAM (ρ=0.626, P=0.002), but not HAM (ρ=0.436, P=0.180) participants. CONCLUSIONS Among women with early-stage breast cancer, body composition is associated with AM, microbiota diversity, and interleukin-6 level. AM may mediate the effects of dietary fiber in improving microbiota composition.

Abstract
BACKGROUND The current study assessed the feasibility of a mentored home-based vegetable gardening intervention and examined changes in health-related outcomes among breast cancer survivors (BCS). METHODS BCS were randomized to either a year-long vegetable gardening intervention to begin immediately or a wait-list control. Master Gardeners mentored participants in planning, planting, and maintaining 3 seasonal gardens over the course of 1 year. Participant accrual, retention, and satisfaction rates of ≥80% served as feasibility (primary outcome) benchmarks. Secondary outcomes (ie, vegetable consumption, physical activity, performance and function, anthropometrics, biomarkers, and health-related quality of life) were collected at baseline and post-intervention (1-year follow-up) using subjective and objective measures. RESULTS The trial surpassed all feasibility benchmarks at 82% of targeted accrual, 95% retention, and 100% satisfaction (ie, experience ratings of "good to excellent" and willingness to "do it again"). Compared with the controls, intervention participants reported significantly greater improvements in moderate physical activity (+14 vs -17 minutes/week) and demonstrated improvements in the 2-Minute Step Test (+22 vs + 10 steps), and Arm Curl (+2.7 vs + 0.1 repetitions) (P values < .05). A trend toward improved vegetable consumption was observed (+0.9 vs + 0.2 servings/day; P = .06). Approximately 86% of participants were continuing to garden at the 2-year follow-up. CONCLUSIONS The results of the current study suggest that a mentored, home-based vegetable gardening intervention is feasible and offers an integrative and durable approach with which to improve health behaviors and outcomes among BCS. Harvest for Health led to the establishment of a group of trained Master Gardeners and gave rise to local and global community-based programs. Larger studies are needed to confirm the results presented herein and to define applicability across broader populations of survivors.

Abstract
To assess the feasibility of a mentored home-based vegetable gardening intervention among Breast Cancer Survivors (BCS) residing in the Birmingham, Alabama metropolitan area. Methods: Using a wait-list control design, BCS were randomized to either a year-long vegetable gardening intervention or a wait-list control. Intervention participants were provided with necessary supplies and paired with a Master Gardener from the Cooperative Extension. Master Gardeners mentored participants in planning, planting, and maintaining 3 seasonal gardens over 12 months, conducted monthly home-visits, and checked in bi-weekly via telephone or email. Feasibility assessment criteria consisted of participant accrual, retention, and satisfaction rates of ≥80%. Target participant accrual was 100. Participant satisfaction data were collected after study completion via structured telephone debriefing. Descriptive statistics were conducted using SPSS V24. Results: 82 BCS (Mage = 60 (39–84); Msurvivorship = 5 years (0.5–23); Mco-morbidities = 3.5 (0–12); ≥2 functional limitations = 86.6%; Caucasian = 73.2%; African-American = 26.8%) enrolled (82% accrual). Of these, four did not complete the study (2 refused to be wait-listed due to not wanting to wait to garden, 1 withdrew due to family obligations, and 1 was lost to follow-up), resulting in an retention rate of 95% over a 1-year period. All BCS who completed the intervention (n = 42) rated their Harvest for Health experience as “Good to Excellent”, reported that they would “do it again”, and planned to “continue to garden.” When asked to rate, on a scale of 1–10 (1 = not at all and 10 = very much), the influence of gardening on motivating behavior change, BCS reported that gardening motivated them to… “eat a healthier diet” (M = 8.38; SD = 2.07), “eat more vegetables” (M = 8.43; SD = 2.08), and “be more physically active” (M = 7.5; SD = 2.73). Conclusions: The vegetable gardening intervention proved to be feasible and provided new knowledge about the influence of gardening on motivating behavior change among BCS. Findings suggest that a mentored home-based vegetable gardening may offer an integrative approach to improve diet, vegetable consumption, and physical activity among BCS. Larger, future studies are warranted.

Abstract
BACKGROUND Holistic approaches are sought to improve lifestyle behaviors and health of cancer survivors long term. OBJECTIVE Our aim was to explore whether a home-based vegetable gardening intervention is feasible and whether it improves diet and other health-related outcomes among older cancer survivors. DESIGN We conducted a feasibility trial in which cancer survivors were randomized to receive a year-long gardening intervention immediately or to a wait-list control arm. Home visits at baseline and 1 year assessed physical performance, anthropometric indices, behavioral and psychosocial outcomes, and biomarkers. PARTICIPANTS/SETTING Participants included 46 older (aged 60+ years) survivors of locoregionally staged cancers across Alabama from 2014 to 2016. Forty-two completed 1-year follow-up. INTERVENTION Cooperative extension master gardeners delivered guidance to establish three seasonal vegetable gardens at survivors' homes. Plants, seeds, and gardening supplies were provided. OUTCOMES Primary outcomes were feasibility targets of 80% accrual and retention, and an absence of serious adverse events; other outcomes were secondary and explored potential benefits. STATISTICAL ANALYSES Baseline to follow-up changes were assessed within and between arms using paired t, McNemar's, and χ2 tests. RESULTS This trial proved to be safe and demonstrated 91.3% retention; 70% of intervention participants rated their experience as "excellent," and 85% would "do it again." Data suggest significantly increased reassurance of worth (+0.49 vs -0.45) and attenuated increases in waist circumference (+2.30 cm vs +7.96 cm) in the gardening vs control arms (P=0.02). Vegetable and fruit consumption increased by approximately 1 serving/day within the gardening arm from baseline to follow-up (mean [standard error]=1.34 [1.2] to 2.25 [1.9] servings/day; P=0.02)] compared to controls (1.22 [1.1] to 1.12 [0.7]; P=0.77; between-arm P=0.06). CONCLUSIONS The home vegetable gardening intervention among older cancer survivors was feasible and suggested improvements in vegetable and fruit consumption and reassurance of worth; data also suggest attenuated increases in waist circumference. Continued study of vegetable gardening interventions is warranted to improve health, health behaviors, and well-being of older cancer survivors.

Abstract
PURPOSE Cancer survivors are at greater risk of comorbidities and functional decline due to physiological and psychological stress which can be measured by salivary cortisol. If saliva is used, multiple samples must be collected to accurately quantify long-term stress; however, fingernail (FN) and toenail (TN) clippings offer an opportunity to measure retrospective cortisol levels in a non-invasive manner. METHODS Three sets of FN and TN clippings were collected at 12-month intervals in conjunction with saliva samples from cancer survivors (n = 109) participating in two clinical trials. FN and TN samples were stored at room temperature (RT); a subset underwent additional processing and freezing before analysis. Cortisol levels were determined via enzyme immunoassay, and correlation coefficients were generated to determine overall correspondence of the individual measures. RESULTS Matched RT and frozen samples were highly correlated for TN (r = 0.950, p = 5.44 × 10-37) and FN (r = 0.784, p = 1.05 × 10-10). Correlations between RT FN and TN were statistically significant (r = 0.621, p = 3.61 × 10- 17), as were frozen FN and TN (r = 0.310, p = 0.0283). RT, but not frozen TN and FN correlated with salivary cortisol (r = 0.580, p = 1.65 × 10- 16 and r = 0.287, p = 0.00042 for TN and FN, respectively). CONCLUSIONS FN and TN cortisol levels correlate with salivary cortisol in adult cancer survivors and may offer a less invasive and convenient means for measuring chronic cortisol levels.

Abstract
Background Poor diet and insufficient physical activity are strongly associated with an increased risk of several cancers. Preclinical studies suggest that lifestyle modifications may exert favorable effects on tumor biology. Randomized controlled trials in the presurgical setting serve as an ideal means to translate this research to humans; however, little is known about the characteristics of patients who enroll in these presurgical trials versus those who do not. Methods Screening databases from three presurgical lifestyle intervention trials for breast and prostate cancer patients conducted at Duke University Medical Center (NCT00049309) and the University of Alabama at Birmingham (NCT02224807 and NCT01886677) were combined for analysis. Demographic and anthropometric differences between enrolled vs. non-enrolled individuals were assessed using Chi-square for categorical variables and t-tests for continuous variables. Results There was no difference in participation rate when comparing minority status or overweight and obese patients. However, obese females were slightly more likely to enroll than women who were overweight (p = 0.110), a trend not seen in men. Women were also less likely than men to participate if their study site was >25 miles from their home (p = 0.034). Patients who had completed a college degree were somewhat less likely to enroll than those with less educational attainment (p = 0.072). Of those who did not enroll, 80% cited a lack of time. Conclusion Similar to other clinical trials, lack of time is a leading barrier to enrollment, and travel/distance appears to be a greater barrier for women in presurgical studies. Larger presurgical lifestyle intervention trials will require tailored strategies to enhance recruitment.

Abstract
Background Obesity and weight gain after the diagnosis of prostate cancer are associated with an increased risk of prostate cancer recurrence and mortality; individualized plans to help prostate cancer survivors maintain or lose weight may be beneficial for recurrence risk reduction. Herein, we explore whether gains in cardiovascular fitness predict successful weight loss in men participating in a weight loss trial (NCT01886677). Methods Forty men were randomized to receive twice-weekly in-person and telephone-based guidance on calorie-restricted diets and aerobic exercise to promote ~0.91 kg/week weight loss, or wait-list control. Thirty-two men completed submaximal VO2 Treadmill Tests (TT), anthropometric measures and two 24-hour dietary recalls at baseline and follow-up. For this secondary analysis, study arms were combined and associations between baseline and longitudinal changes in physiological effort (PE, measured by heart rate during TT), predicted VO2max, caloric intake and weight loss were analyzed. Results Men lost 3.4 kg in 50 ± 23 days on the study. Multivariate linear regression indicated weight change was associated with change in PE at stage 2TT (Partial R = 0.635, p < 0.001), days on study (Partial R = −0.589, p = 0.002) and change in caloric intake (Partial R = 0.457, p = 0.019). Conclusions Untrained men experiencing elevated heart rates during stage 2TT at baseline were able to achieve greater weight loss over the study period; this association was strengthened by a decrease in PE at the same level from baseline to follow-up concomitant with reduced caloric intake. Therefore, for these middle-aged and older men with lower aerobic fitness, exercise appears to be a key factor in achieving higher degrees of weight loss.

Abstract
BACKGROUND Diet and obesity influence prostate cancer risk and progression-effects that may be mediated through the gut microbiome. OBJECTIVE Our aim was to explore relationships among diet, gut microbes, and Gleason sum in overweight and obese prostate cancer patients enrolled in a presurgical weight-loss trial. DESIGN Randomized controlled trial (NCT01886677) secondary analysis. PARTICIPANTS/SETTING In 2013-2014, 40 prostate cancer patients in the southeastern United States were randomized and allocated equally to weight-loss and wait-list control arms while they awaited prostatectomy; stool samples were collected on a subset of 22 patients. INTERVENTION Registered dietitian nutritionists and exercise physiologists provided semi-weekly in-person and telephone-based guidance on calorie-restricted diets and exercise to promote an approximate weight loss of 0.91 kg/wk. MAIN OUTCOME MEASURES Baseline and follow-up 24-hour dietary recalls were conducted and analyzed (using the Automated Self-Administered 24-hour dietary recall system; National Cancer Institute, Bethesda, MD) for macronutrients, micronutrients, and food groups. Microbiome analysis targeting the V4 region of the 16S ribosomal RNA gene was performed on fecal samples. Biopsy Gleason sum data were accessed from diagnostic pathology reports. STATISTICAL ANALYSES PERFORMED Associations between dietary factors and operational taxonomic units were determined by β-diversity analysis. Wilcoxon signed rank, and Mann-Whitney U testing assessed within- and between-arm differences. Associations between Gleason sum and operational taxonomic units, and diet and operational taxonomic units, were analyzed using Spearman correlations. RESULTS At baseline, Proteobacteria (median 0.06, interquartile range 0.01 to 0.16) were abundant, with four orders positively associated with Gleason sum. Gleason sum was associated with Clostridium (ρ=.579; P=0.005) and Blautia (ρ=-0.425, P=0.049). Increased red meat consumption from baseline was associated with Prevotella (ρ=-.497; P=0.018) and Blautia (ρ=.422; P=0.039). Men who increased poultry intake had decreased Clostridiales abundance (P=0.009). CONCLUSIONS This hypothesis-generating study provides a starting point for investigating the relationships between the fecal microbiome, diet, and prostate cancer. Adequately powered studies are required to further explore and validate these findings.

Abstract
INTRODUCTION Obesity is a known risk factor for postmenopausal breast cancer and is associated with poorer prognosis for premenopausal and postmenopausal patients; however, the aetiological mechanisms are unknown. Preclinical studies support weight loss via caloric restriction and increased physical activity as a possible cancer control strategy, though few clinical studies have been conducted. We undertook a feasibility trial among women recently diagnosed with stage 0-II breast cancer hypothesising that presurgical weight loss would be feasible, safe and result in favourable changes in tumour markers and circulating biomarkers. METHODS AND ANALYSIS A two-arm randomised controlled trial among 40 overweight or obese women, newly diagnosed with stage 0-II breast cancer and scheduled for surgery was planned. The attention control arm received upper body progressive resistance training and diet counselling to correct deficiencies in nutrient intake; the experimental arm received the same plus counselling on caloric restriction and aerobic exercise to achieve a weight loss of 0.68-0.919 kg/week. In addition to achieving feasibility benchmarks (accruing and retaining at least 80% of participants, and observing no serious adverse effects attributable to the intervention), we will explore the potential impact of an acute state of negative energy balance on tumour proliferation rates (Ki-67), as well as other tumour markers, serum biomarkers, gene expression, microbiome profiles and other clinical outcomes (eg, quality of life). Outcomes for the 2 study arms are compared using mixed models repeated-measures analyses. ETHICS AND DISSEMINATION Ethics approval was received from the University of Alabama at Birmingham Institutional Review Board (Protocol number F130325009). Study findings will be disseminated through peer-reviewed publications. Given that this is one of the first studies to investigate the impact of negative energy balance directly on tumour biology in humans, larger trials will be pursued if results are favourable.

Abstract
BACKGROUND Cancer survivors suffer from long-term adverse effects that reduce health-related quality of life (QOL) and physical functioning, creating an urgent need to develop effective, durable, and disseminable interventions. Harvest for Health, a home-based vegetable gardening intervention, holds promise for these domains. METHODS This report describes the methods and recruitment experiences from two randomized controlled feasibility trials that employ a waitlist-controlled design. Delivered in partnership with Cooperative Extension Master Gardeners, this intervention provides one-on-one mentorship of cancer survivors in planning and maintaining three seasonal vegetable gardens over 12months. The primary aim is to determine intervention feasibility and acceptability; secondary aims are to explore effects on objective and subjective measures of diet, physical activity and function, and QOL and examine participant factors associated with potential effects. One trial is conducted exclusively among 82 female breast cancer survivors residing in the Birmingham, AL metropolitan area (BBCS); another broadly throughout Alabama among 46 older cancer survivors aged >60 (ASCS). RESULTS Response rates were 32.6% (BBCS) and 52.3% (ASCS). Both trials exceeded 80% of their accrual target. Leading reasons for ineligibility were removal of >10 lymph nodes (lymphedema risk factor), lack of physician approval, and unwillingness to be randomized to the waitlist. CONCLUSION To date, recruitment and implementation of Harvest for Health appears feasible. DISCUSSION Although both studies encountered recruitment challenges, lessons learned can inform future larger-scale studies. Vegetable gardening interventions are of interest to cancer survivors and may provide opportunities to gain life skills leading to improvements in overall health and QOL.

Abstract
Background Obesity is associated with tumor aggressiveness and disease-specific mortality for more than 15 defined malignancies, including prostate cancer. Preclinical studies suggest that weight loss from caloric restriction and increased physical activity may suppress hormonal, energy-sensing, and inflammatory factors that drive neoplastic progression; however, exact mechanisms are yet to be determined, and experiments in humans are limited. Methods We conducted a randomized controlled trial among 40 overweight or obese, newly-diagnosed prostate cancer patients who elected prostatectomy to explore feasibility of a presurgical weight loss intervention that promoted a weight loss of roughly one kg. week−1 via caloric restriction and physical activity, as well as to assess effects on tumor biology and circulating biomarkers. Measures of feasibility (accrual, retention, adherence, and safety) were primary endpoints. Exploratory aims were directed at the intervention’s effect on tumor proliferation (Ki-67) and other tumor markers (activated caspase-3, insulin and androgen receptors, VEGF, TNFβ, NFκB, and 4E-BP1), circulating biomarkers (PSA, insulin, glucose, VEGF, TNFβ, leptin, SHBG, and testosterone), lymphocytic gene expression of corresponding factors and cellular bioenergetics in neutrophils, and effects on the gut microbiome. Consenting patients were randomized in a 1:1 ratio to either: 1) weight loss via a healthful, guidelines-based diet and exercise regimen; or 2) a wait-list control. While biological testing is currently ongoing, this paper details our methods and feasibility outcomes. Results The accrual target was met after screening 101 cases (enrollment rate: 39.6 %). Other outcomes included a retention rate of 85 %, excellent adherence (95 %), and no serious reported adverse events. No significant differences by age, race, or weight status were noted between enrollees vs. non-enrollees. The most common reasons for non-participation were “too busy” (30 %), medical exclusions (21 %), and “distance” (16 %). Conclusions Presurgical trials offer a means to study the impact of diet and exercise interventions directly on tumor tissue, and other host factors that are feasible and safe, though modifications are needed to conduct trials within an abbreviated period of time and via distance medicine-based approaches. Pre-surgical trials are critical to elucidate the impact of lifestyle interventions on specific mechanisms that mediate carcinogenesis and which can be used subsequently as therapeutic targets.

Abstract
Childhood obesity in the USA has more than tripled in the last three decades, and the prevalence is higher in the Mississippi Delta. Insight into the social, cultural and environmental factors that influence inequity can inform efforts to mediate health disparities. Focus groups (n = 12) among parents/guardians of elementary school children (n = 44) and teachers (n = 59) in the Mississippi Delta were used to investigate barriers and facilitators of healthy eating. Transcriptions were analyzed for themes. A strong preference for junk food among children and the pervasiveness of junk foods in schools and communities were cited as barriers to healthy eating. Potential facilitators of healthy eating included desire to avoid chronic disease, effort to limit junk food consumption and school support. Despite support for efforts to improve nutrition in the Delta, participants voiced a sense of inevitability related to children's consumption of unhealthy foods. This study suggests that parents and teachers express concern related to eating habits of children, yet they experience barriers to healthy eating which contribute to a sense of disempowerment. Improving health in the Mississippi Delta requires comprehensive strategies that offer its citizens a sense of agency.

Abstract
BACKGROUND AND AIM The purpose of this study was to examine the association between physical activity (PA), caloric intake, and Metabolic Syndrome (MetS) in a representative sample of the United States population. METHODS AND RESULTS Data for 4327 adults from 2007 to 2010 NHANES were analyzed. MetS was defined using both ATPIII and AHA/NHLBI criteria. Weekly moderate and vigorous physical activity (PA) minutes from work, leisure-time, and transportation PA were used to estimate Total Energy Expenditure (TEE) from Basal Metabolic Rate (BMR) using the Harris-Benedict equation. Average total calories (KCAL) from two 24-h dietary recalls were used to compare energy intake and expenditure between subjects with and without MetS. An alpha of 0.05 was used to determine statistical differences. The age adjusted prevalence of MetS was 21.9% (95% CI 20.1-23.6) and 36.8% (34.7-39.0) using ATPIII and AHA/NHLBI criteria, respectively. The estimated population mean for KCAL/TEE was 0.83 (95% CI 0.82-0.84), and the mean for KCAL/BMR was 1.25 (95% CI 1.23-1.27). Subjects without MetS (MetS-) reported 36 ± 13 (ATPIII) and 45 ± 18 (AHA/NHLBI) more daily moderate PA minutes than subjects with MetS (MetS+). At each level of PA, MetS- consumed more calories relative to BMR and TEE than MetS+. For both normal and overweight adults, KCAL/BMR was higher for MetS- than MetS+. For all BMI groups, there were no differences between MetS- and MetS+ with respect to KCAL/TEE. Though MetS+ adults in either MetS criteria were generally less physically active, MetS- adults maintained a higher caloric intake relative to estimated energy needs. CONCLUSIONS These results suggest energy needs may be distorted in Metabolic Syndrome and increased physical activity may be more protective than reduced caloric intake.

Abstract
BACKGROUND The goal of this study was to examine the relationship between macronutrient and micronutrient intake and metabolic syndrome within race and gender cohorts of young US adults. METHODS The 2007-2010 National Health and Nutrition Examination Survey (NHANES) data for adults (n=2440) aged 20-59 were analyzed. Two 24-hr dietary recalls were used to measure intake of total calories, macronutrients, and 20 vitamins and minerals. Metabolic syndrome and its components were defined by the National Heart, Lung and Blood Institute criteria. Differences in statistical tests were noted when significant at P<0.05. RESULTS Prevalence of metabolic syndrome among 20- to 59-year-old adults was 30.4% [95% confidence interval 27.6-33.2]. Among cohorts, metabolic syndrome was highest in black women and white men, and lowest in black men and white women. Regression analysis indicated that no macronutrients were associated with greater risk of metabolic syndrome. For relative macronutrient intake, men with metabolic syndrome consumed more polyunsaturated fats, whereas women with metabolic syndrome consumed more total, saturated and monounsaturated fats and less fiber and starch than women without metabolic syndrome. Among races, white men and women consumed greater absolute quantities of all macronutrients except carbohydrates and sugar. Micronutrient intake was greatest for white men and women; women without metabolic syndrome had greater micronutrient adequacy than women with metabolic syndrome. CONCLUSION Nutrient intake varied between race/gender cohorts; however, there were few clinically significant differences in nutrient intake between those with and without metabolic syndrome. Diet may be marginally related to diagnosis of metabolic syndrome.
