Abstract
INTRODUCTION Globally 38.9 million children under age 5 have overweight or obesity, leading to type 2 diabetes, cardiovascular complications, depression, and poor educational outcomes. Obesity is difficult to reverse and lifestyle behaviors (healthy or unhealthy) can persist from 1.5 years of age. Targeting caregivers to help address modifiable behaviors may offer a viable solution. OBJECTIVE Evaluate the impact of multicomponent family interventions on weight-based outcomes in early childhood and explore related secondary behavior outcomes. METHODS Four databases were searched (1/2017-6/2022) for randomized controlled trials (RCTs) of obesity-prevention interventions for children (1-5 years). Eligible studies included an objectively measured weight-based outcome, family interventions targeting the caregiver or family, and interventions including at least two behavioral components of nutrition, physical activity, or sleep. RESULTS Eleven interventions were identified consisting of four delivery modes: self-guided (n = 3), face-to-face group instruction (n = 3), face-to-face home visits (n = 2), and multiple levels of influence (n = 3). The reviewed studies reported almost no significant effects on child weight-based outcomes. Only two studies (one was an underpowered pilot study) resulted in significant positive child weight-management outcomes. Seven of the interventions significantly improved children's dietary intake. CONCLUSION Except for one, the reviewed studies reported that family based interventions had no significant effects on child weight-based outcomes. Future studies of this type should include measurements of age and sex-based body mass index (BMI) and trajectories, and also examine other important benefits to the children and families.

Abstract
PURPOSE Older survivors of leukemia and lymphoma often experience long-term effects of chemotherapy. We described common concerns related to their cancer and treatment in older survivors of leukemia and non-Hodgkin lymphoma (NHL) and assessed correlates of these concerns. METHODS We utilized data from the Women's Health Initiative (WHI) Life and Longevity After Cancer (LILAC) study that recruited post-menopausal women aged 50-79. Participants diagnosed with leukemia and NHL were included (n = 420). They were asked about 14 areas of current concerns related to their cancer and treatment and to rate each from 0 (no concern) to 2 (major concern), with total scores ranging from 0 to 28. Linear regression was used to assess factors correlated with the concern score, and logistic regression for factors correlated with the three most common concerns. RESULTS Mean age at assessment was 81 years (range 69-99); 72% reported at least one concern, and median concern score among these survivors was 3.5 (Q1-Q3 2-5). Factors significantly correlated with concern scores were sadness, pain, distress, higher prior symptom count, and loneliness (all p < 0.05). Significant factors correlated with common concerns were (1) fatigue/sleep: sadness/depression, distress, higher prior symptom count, greater loneliness, and worse physical functioning; (2) physical functioning/activity: older age, public insurance, higher body mass index, pain, worse QoL, and higher treatment-related comorbidities; (3) memory/concentration: prior chemotherapy or radiation, worse QoL, higher prior symptom count, and greater loneliness (all p < 0.05). CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS Almost three-quarters of older survivors of leukemia and lymphoma reported at least one concern; a multifaceted intervention may be needed to address these concerns.

Abstract
Background Cocoa extract and multivitamins have been proposed to reduce the risk of cardiovascular disease (CVD) and cancer, respectively. However, few randomized clinical trials have tested their long-term effects on these outcomes. Methods The COcoa Supplement and Multivitamin Outcomes Study (COSMOS) is a randomized, double-blind, placebo-controlled, 2 × 2 factorial trial of a cocoa extract supplement and a multivitamin supplement to reduce the risk of CVD and cancer. Here we describe the pragmatic, hybrid design of the trial and baseline characteristics of the trial participants. Results The nationwide study population includes 21,442 U.S. women aged ≥65 years and men aged ≥60 years without baseline myocardial infarction (MI), stroke, or a recent (within the past 2 years) cancer diagnosis. Participants were randomized in a 2 × 2 factorial design to one of four groups: (1) cocoa extract (containing 500 mg/d flavanols, including 80 mg (-)-epicatechin) and a multivitamin (Centrum Silver©); (2) cocoa extract and multivitamin placebo; (3) multivitamin and cocoa extract placebo; or (4) both placebos. Randomization successfully distributed baseline demographic, clinical, behavioral, and dietary characteristics across treatment groups. Baseline biospecimens were collected from 6867 participants, with at least one follow-up biospecimen from 2142 participants. The primary outcome for the cocoa extract intervention is total CVD (a composite of MI, stroke, cardiovascular mortality, coronary revascularization, unstable angina requiring hospitalization, carotid artery surgery, and peripheral artery surgery); the primary outcome for the multivitamin intervention is total invasive cancer. Conclusion COSMOS will provide important information on the health effects of cocoa extract and multivitamin supplementation in older U.S. adults.

Abstract
BACKGROUND Cocoa extract is a source of flavanols that favorably influence vascular risk factors in small and short-term trials, yet effects on clinical cardiovascular events are untested. OBJECTIVES We examined whether cocoa extract supplementation decreases total cardiovascular disease (CVD) among older adults. METHODS We conducted a randomized, double-blind, placebo-controlled, 2-by-2 factorial trial of cocoa extract supplementation and multivitamins for prevention of CVD and cancer among 21,442 US adults (12,666 women aged ≥65 y and 8776 men aged ≥60 y), free of major CVD and recently diagnosed cancer. The intervention phase was June 2015 through December 2020. This article reports on the cocoa extract intervention. Participants were randomly assigned to a cocoa extract supplement [500 mg flavanols/d, including 80 mg (-)-epicatechin] or placebo. The primary outcome was a composite of confirmed incident total cardiovascular events, including myocardial infarction (MI), stroke, coronary revascularization, cardiovascular death, carotid artery disease, peripheral artery surgery, and unstable angina. RESULTS During a median follow-up of 3.6 y, 410 participants taking cocoa extract and 456 taking placebo had confirmed total cardiovascular events (HR: 0.90; 95% CI: 0.78, 1.02; P = 0.11). For secondary endpoints, HRs were 0.73 (95% CI: 0.54, 0.98) for CVD death, 0.87 (95% CI: 0.66, 1.16) for MI, 0.91 (95% CI: 0.70, 1.17) for stroke, 0.95 (95% CI: 0.77, 1.17) for coronary revascularization, neutral for other individual cardiovascular endpoints, and 0.89 (95% CI: 0.77, 1.03) for all-cause mortality. Per-protocol analyses censoring follow-up at nonadherence supported a lower risk of total cardiovascular events (HR: 0.85; 95% CI: 0.72, 0.99). There were no safety concerns. CONCLUSIONS Cocoa extract supplementation did not significantly reduce total cardiovascular events among older adults but reduced CVD death by 27%. Potential reductions in total cardiovascular events were supported in per-protocol analyses. Additional research is warranted to clarify whether cocoa extract may reduce clinical cardiovascular events. This trial is registered at www.clinicaltrials.gov as NCT02422745.

Abstract
BACKGROUND Although older adults commonly take multivitamin-multimineral (MVM) supplements to promote health, evidence on the use of daily MVMs on invasive cancer is limited. OBJECTIVES The study objective was to determine if a daily MVM decreases total invasive cancer among older adults. METHODS We performed a randomized, double-blind, placebo-controlled, 2-by-2 factorial trial of a daily MVM and cocoa extract for prevention of cancer and cardiovascular disease (CVD) among 21,442 US adults (12,666 women aged ≥65 y and 8776 men aged ≥60 y) free of major CVD and recently diagnosed cancer. The intervention phase was from June 2015 through December 2020. This article reports on the MVM intervention. Participants were randomly assigned to daily MVM or placebo. The primary outcome was total invasive cancer, excluding nonmelanoma skin cancer. Secondary outcomes included major site-specific cancers, total CVD, all-cause mortality, and total cancer risk among those with a baseline history of cancer. RESULTS During a median follow-up of 3.6 y, invasive cancer occurred in 518 participants in the MVM group and 535 participants in the placebo group (HR: 0.97; 95% CI: 0.86, 1.09; P = 0.57). We observed no significant effect of a daily MVM on breast cancer (HR: 1.06; 95% CI: 0.79, 1.42) or colorectal cancer (HR: 1.30; 95% CI: 0.80, 2.12). We observed a protective effect of a daily MVM on lung cancer (HR: 0.62; 95% CI: 0.42, 0.92). The composite CVD outcome occurred in 429 participants in the MVM group and 437 participants in the placebo group (HR: 0.98; 95% CI: 0.86, 1.12). MVM use did not significantly affect all-cause mortality (HR: 0.93; 95% CI: 0.81, 1.08). There were no safety concerns. CONCLUSIONS A daily MVM supplement, compared with placebo, did not significantly reduce the incidence of total cancer among older men and women. Future studies are needed to determine the effects of MVMs on other aging-related outcomes among older adults. This trial is registered at www.clinicaltrials.gov as NCT02422745.

Abstract
BACKGROUND An inventory of cancer survivorship cohorts is necessary to identify important gaps in what is being studied among cancer survivors. METHODS We conducted an environmental scan of cancer survivor cohorts to determine the scope and scale of information collected on demographic, biopsychosocial, and selected clinical variables from cancer survivors. Cohorts were eligible for inclusion in the environmental scan if the study was conducted in the United States, reported in English, and consisted of data collected from cancer survivors postdiagnosis and followed for at least 1 year. RESULTS Out of the 131 cohorts identified, 62 were eligible. There were 23 cancer sites represented, and more than half of the studies included breast cancer survivors (n = 34). The next most commonly included cancers were leukemia (n = 22) and lymphoma (n = 23). The majority (n = 59) collected information on clinical characteristics and basic diagnostic information, patient demographic characteristics (n = 57), patient-reported symptoms (n = 44), lifestyle (n = 45), and psychologic characteristics (n = 42). Half collected biospecimens (n = 35) and biomarkers (n = 35); fewer collected CAM use (n = 19) and social characteristics (n = 27). CONCLUSIONS Extensive data are available in cancer cohorts to study important questions relevant to cancer survivors. Cohorts should consider collecting information on social and environmental factors, as well as biospecimen collection and biomarker analyses, and should include survivors from cancer sites less likely to be studied. IMPACT This information can assist researchers in understanding the types of information currently being gathered from cancer survivors for further analysis and identify areas where more research is needed.

Abstract
Background Cervical cancer is the fourth most common cancer in women, and we recently reported human leukocyte antigen (HLA) alleles showing strong associations with cervical neoplasia risk and protection. HLA ligands are recognized by killer immunoglobulin-like receptors (KIRs) expressed on a range of immune cell subsets, governing their proinflammatory activity. We hypothesized that the inheritance of particular HLA-KIR combinations would increase cervical neoplasia risk. Methods Here, we used HLA and KIR dosages imputed from single-nucleotide polymorphism genotype data from 2143 cervical neoplasia cases and 13858 healthy controls of European decent. Results The following 4 novel HLA alleles were identified in association with cervical neoplasia, owing to their linkage disequilibrium with known cervical neoplasia-associated HLA-DRB1 alleles: HLA-DRB3*9901 (odds ratio [OR], 1.24; P = 2.49 × 10-9), HLA-DRB5*0101 (OR, 1.29; P = 2.26 × 10-8), HLA-DRB5*9901 (OR, 0.77; P = 1.90 × 10-9), and HLA-DRB3*0301 (OR, 0.63; P = 4.06 × 10-5). We also found that homozygosity of HLA-C1 group alleles is a protective factor for human papillomavirus type 16 (HPV16)-related cervical neoplasia (C1/C1; OR, 0.79; P = .005). This protective association was restricted to carriers of either KIR2DL2 (OR, 0.67; P = .00045) or KIR2DS2 (OR, 0.69; P = .0006). Conclusions Our findings suggest that HLA-C1 group alleles play a role in protecting against HPV16-related cervical neoplasia, mainly through a KIR-mediated mechanism.

Abstract
OBJECTIVE Oesophageal adenocarcinoma (OA) incidence has risen sharply in Western countries over recent decades. Local and systemic inflammation is considered an important contributor to OA pathogenesis. Established risk factors for OA and its precursor, Barrett's oesophagus (BE), include symptomatic reflux, obesity and smoking. The role of inherited genetic susceptibility remains an area of active investigation. Here, we explore whether germline variation related to inflammatory processes influences susceptibility to BE/OA. DESIGN We used data from a genomewide association study of 2515 OA cases, 3295 BE cases and 3207 controls. Our analysis included 7863 single-nucleotide polymorphisms (SNPs) in 449 genes assigned to five pathways: cyclooxygenase (COX), cytokine signalling, oxidative stress, human leucocyte antigen and nuclear factor-κB. A principal components-based analytic framework was employed to evaluate pathway-level and gene-level associations with disease risk. RESULTS We identified a significant signal for the COX pathway in relation to BE risk (p=0.0059, false discovery rate q=0.03), and in gene-level analyses found an association with microsomal glutathione-S-transferase 1 (MGST1); (p=0.0005, q=0.005). Assessment of 36 MGST1 SNPs identified 14 variants associated with elevated BE risk (q<0.05). Four of these were subsequently confirmed (p<5.5×10-5) in a meta-analysis encompassing an independent set of 1851 BE cases and 3496 controls, and are known strong expression quantitative trait loci for MGST1. Three such variants were associated with similar elevations in OA risk. CONCLUSIONS This study provides the most comprehensive evaluation of inflammation-related germline variation in relation to risk of BE/OA and suggests that variants in MGST1 influence disease susceptibility.

Abstract
A small percentage of women with cervical HPV infection progress to cervical neoplasia, and the risk factors determining progression are incompletely understood. We sought to define the genetic loci involved in cervical neoplasia and to assess its heritability using unbiased unrelated case/control statistical approaches. We demonstrated strong association of cervical neoplasia with risk and protective HLA haplotypes that are determined by the amino-acids carried at positions 13 and 71 in pocket 4 of HLA-DRB1 and position 156 in HLA-B. Furthermore, 36% (standard error 2.4%) of liability of HPV-associated cervical pre-cancer and cancer is determined by common genetic variants. Women in the highest 10% of genetic risk scores have approximately >7.1% risk, and those in the highest 5% have approximately >21.6% risk, of developing cervical neoplasia. Future studies should examine genetic risk prediction in assessing the risk of cervical neoplasia further, in combination with other screening methods. Around 1% of women with cervical human papillomavirus (HPV) infection progress to cervical cancer. Previous studies had indicated that a person’s genetic makeup could predispose to HPV-associated cervical cancer, and that some of the genes likely to be involved include the immune-related human leukocyte antigen (HLA) genes among the major histocompatibility complex (MHC). However, it has been difficult to determine which alleles might be associated with cervical pre-cancer or cancer due to the complex and high level of co-inheritance of MHC alleles. Here, we performed a genome-wide association study that assessed the correlation of genetic variants among those with cervical cancer and healthy controls. We show that host genetics is a major determinant of HPV-associated cervical cancer, with 36% of liability due to common genetic variants in the population, and identify both risk and protective HLA alleles. Our study was also sufficiently powerful to identify particular residue variants on a number of the immune-related proteins that provide risk or protection, providing further insight into the biological basis for cervical cancer development. Our findings could lay the foundation for screening for people at increased risk of developing cancer following HPV infection, and aid in the treatment and prognosis of cervical cancer.

Abstract
It has been suggested that ghrelin may play a role in growth hormone (GH) responses to exercise. The present study was designed to determine whether ghrelin, GH, insulin-like growth factor-I (IGF-I), and IGF-binding protein-3 (IGFBP-3) were altered by a progressively intense running protocol. Six well-trained male volunteers completed a progressively intense intermittent exercise trial on a treadmill that included four exercise intensities: 60%, 75%, 90%, and 100% of Vo2max. Blood samples were collected before exercise, after each exercise intensity, and at 15 and 30 mins following the exercise protocol. Subjects also completed a separate control trial at the same time of day that excluded exercise. GH changed significantly over time, and GH area under the curve (AUC) was significantly higher in the exercise trial than the control trial. Area under the curve IGF-I levels for the exercise trial were significantly higher than the control trial. There was no difference in the ghrelin and IGFBP-3 responses to the exercise and control trials. Pearson correlation coefficients revealed significant relationships between ghrelin and both IGF-I and IGFBP-3; however, no relationship between ghrelin and GH was found. In conclusion, intense running produces increases in total IGF-I concentrations, which differs from findings in previous studies using less rigorous running protocols and less frequent blood sampling regimens. Moreover, running exercise that produces substantial increases in GH does not affect peripheral ghrelin levels; however, significant relationships between ghrelin and both IGF-I and IGFBP-3 exist during intense intermittent running and recovery, which warrants further investigation.

Abstract
Organ transplant recipients (OTRs) have a substantially elevated risk of squamous cell skin carcinoma (SCSC), largely attributed to immunosuppressive medications used to prevent graft rejection, although data to support the role of newer drugs in SCSC risk are sparse. We investigated the association between immunosuppressive medications and SCSC risk among cardiac and renal transplant recipients in the SCOT cohort study. Incident cases were ascertained through medical record review after self-report of skin biopsy (n = 170). Controls without SCSC (n = 324) were matched to cases on sex, age, race, transplant year, hospital, donor type, organ transplanted, and time between transplantation and interview. Conditional logistic regression was used to evaluate the association between specific medications and SCSC. Users of the antimetabolite azathioprine were more than twice as likely to develop SCSC (odds ratio [OR] = 2.67, 95% confidence interval [CI] 1.23-5.76). In contrast, the newer antimetabolite preparations (i.e., mycophenolic acid [MPA]) were associated with lower SCSC risk (OR = 0.45, 95% CI 0.29-0.69). This inverse association between MPA and SCSC persisted among OTRs with no history of azathioprine use, even after adjustment for simultaneous use of the calcineurin inhibitor tacrolimus (OR = 0.52, 95% CI 0.32-0.84). Our data suggest that the increased risk of SCSC historically associated with azathioprine is not seen in OTRs prescribed newer regimens, including MPA and tacrolimus.

Abstract
OBJECTIVE Persistent infection with oncogenic human papillomavirus (HPV) is known to be the necessary cause of cervical cancer and a majority of vulvar cancers. Persistent HPV infections must evade host immune responses, including cytokines released by activated T-helper (Th) cells. In this study, we investigated the risk of cervical and vulvar cancers associated with common genetic variations in 560 tagging single-nucleotide polymorphisms (SNPs) in candidate cytokine genes. METHODS The study included 399 invasive squamous cell carcinomas (SCCs) and 502 in situ or invasive adenocarcinomas (AC) of the cervix; 357 in situ or invasive vulvar SCC; and 1109 controls from the Seattle-area case-control studies of HPV-related cancers. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) using a log additive model, with adjustment for multiple testing. RESULTS Statistically significant risks were observed for HPV16-containing SCC of the cervix with the variant allele rs879576 in IL17RA and rs2229094 in TNF [OR, 95% CI and multiple-testing corrected p: 1.91 (1.30-2.79), p=0.018 and 0.61 (0.45-0.83), p=0.02, respectively]. We also observed significantly increased risk of HPV-positive vulvar cancers associated with variant alleles in CSF2 (rs25882 and rs27438, 26-28% increased risk) and IL-12B (rs2569254 and rs3181225, 40-41% increased risk) genes. CONCLUSIONS We found that variation in several Th-cytokine genes is significantly associated with cervical and vulvar cancer risk. The strong association between these HPV-related cancers and common variation in cytokine genes in the Th1 and Th17 pathways may be important for development of new therapies.

Abstract
Abstract
Hormone replacement therapy (HRT) has been associated with increased risks of cancers of the breast, ovary, endometrium and colon. The exact mechanism underlying these associations remains unknown, though changes to DNA methylation have been suggested to play a role. To explore this compelling mechanism, we examined genome-wide DNA methylation in blood among 92 women with and without a history of long-term HRT use that were recruited as controls for a previous case-control study of breast cancer. HRT exposure was defined as estrogen use for at least 10 years among women with hysterectomy (n = 23) and as estrogen and progesterone use for at least 5 years among women without hysterectomy (n = 23). Women with and without hysterectomy and no history of HRT use were selected for comparison (n = 46). Genome-wide methylation was measured in DNA from blood using the Illumina Infinium HumanMethylation450 BeadChip platform. After excluding loci on sex chromosomes, loci with detection p-values <0.01 in ≥20% of samples, loci within 50 base pairs of at least one variant with a minor allele frequency of >1%, and loci with cross-reactive probes, 343,349 loci were included for analysis. Separately for the hysterectomy and non-hysterectomy groups, the M-value for each locus (defined as the logit of methylated probe intensity and overall intensity using a 0.001 threshold) was regressed against HRT status in linear models to adjust for age and BMI. The Significance Analysis of Microarrays (SAM) method was used to account for multiple comparisons by controlling the false discovery rate. Preliminary analyses have revealed significant differential methylation at four loci, including cg19987229, cg22610211, cg08440572, and cg11372436. For example, estrogen and progesterone users among women without hysterectomy were found to have 74% greater methylation at a locus near the transcription start site of the SOD3 gene (q<0.001). This may lead to decreased expression of the SOD3 gene which is involved in oxidative stress response. Data analyses at the level of gene, gene region, and CpG island are currently in progress. Differentially methylated loci identified in this study should be evaluated in association with breast cancer risk in a prospective study of breast cancer with detailed data on HRT use. If significant associations are observed, these loci could conceivably be used in screening efforts to identify HRT users that may be particularly susceptible to developing breast cancer.

Abstract
Background: Associations between human leukocyte antigens (HLA) alleles and cervical cancer are largely representative of squamous cell carcinoma (SCC), the major histologic subtype. We evaluated the association between HLA class I (A, B, and C) and class II (DRB1 and DQB1) loci and risk of cervical adenocarcinoma (ADC), a less common but aggressive histologic subtype. Methods: We pooled data from the Eastern and Western US Cervical Cancer studies, and evaluated the association between individual alleles and allele combinations and ADC (n = 630 ADC; n = 775 controls). Risk estimates were calculated for 11 a priori (based on known associations with cervical cancer regardless of histologic type) and 38 non a priori common alleles, as odds ratios (OR) and 95% confidence intervals (CI), adjusted for age and study. In exploratory analysis, we compared the risk associations between subgroups with HPV16 or HPV18 DNA in ADC tumor tissues in the Western US study cases and controls. Results: Three of the a priori alleles were significantly associated with decreased risk of ADC [DRB1*13:01 (OR = 0.61; 95% CI: 0.41–0.93), DRB1*13:02 (OR = 0.49; 95% CI: 0.31–0.77), and DQB1*06:03 (OR = 0.64; 95% CI: 0.42–0.95)]; one was associated with increased risk [B*07:02 (OR = 1.39; 95% CI: 1.07–1.79)]. Among alleles not previously reported, DQB1*06:04 (OR = 0.46; 95% CI: 0.27–0.78) was associated with decreased risk of ADC and remained significant after correction for multiple comparisons, and C*07:02 (OR = 1.41; 95% CI: 1.09–1.81) was associated with increased risk. We did not observe a difference by histologic subtype. ADC was most strongly associated with increased risk with B*07:02/C*07:02 alleles (OR = 1.33; 95% CI: 1.01–1.76) and decreased risk with DRB1*13:02/DQB1*06:04 (OR = 0.41; 95% CI: 0.21–0.80). Conclusion: Results suggest that HLA allele associations with cervical ADC are similar to those for cervical SCC. An intriguing finding was the difference in risk associated with several alleles restricted to HPV16 or HPV18-related tumors, consistent with the hypothesis that HLA recognition is HPV type-specific.

Abstract
Squamous cell skin cancer (SCSC) disproportionately affects organ transplant recipients, and may be related to increased viral replication in the setting of immune suppression. We conducted a nested case–control study among transplant recipients to determine whether SCSC is associated with antibodies to cutaneous human papillomaviruses (HPV), to genes associated with a rare genetic susceptibility to HPV (TMC6/TMC8), or to human polyomaviruses (HPyV). Cases (n = 149) had histologically confirmed SCSC, and controls (n = 290) were individually matched to cases on time since transplant, type of transplant, gender, and race. All subjects had serum drawn immediately prior to transplant surgery. Antibodies to 25 cutaneous HPVs and six HPyVs were assayed by detection of binding to virus-like particles, and 11 TMC6/8 variants were genotyped. After correction for multiple comparisons, only antibodies to HPV37 were associated with SCSC (OR 2.0, 95% CI 1.2–3.4). Common genetic variants of TMC6/8 were not associated with SCSC, but three variants in TMC8 (rs12452890, rs412611, and rs7208422) were associated with greater seropositivity for species 2 betapapillomaviruses among controls. This study suggests that some betaHPVs, but not polyomaviruses, may play a role in the excess risk of SCSC among transplant recipients.

Abstract
UNLABELLED Chemokines are small molecules that when secreted by tissues under pathological conditions such as inflammation are believed to be involved in carcinogenesis. Recent reports have found that the genetic variation in chemokine encoding genes are associated with risk of breast cancer. METHODS Using data from a population-based case-control study of 845 invasive breast cases and 807 controls, we genotyped 34 single nucleotide polymorphisms (SNPs) in 8 chemokine candidate genes (CCL3, CCL4, CCL5, CCL20, CCR5, CCR6, CXCL12 and CXCR4). Associations with breast cancer were computed for individual SNPs, groups of SNPs within genes, and in a gene-set analysis. We also performed a meta-analysis of CXCL12 rs1801157 and a haplotype analysis for two SNPs: CXCR4 rs2228014 and CXCL12 rs1801157. RESULTS We found no significant associations between the risk of breast cancer and any individual SNPs, single genes, or combined gene sets. Some individual variants were marginally associated with some histologic subtypes, but these associations were not significant after adjustment for multiple comparisons. In the meta-analysis of five studies of European ancestry, CXCL12 rs1801157 was marginally associated with breast cancer risk (OR=1.14, 95% CI: 1.00, 1.30). CONCLUSIONS Our findings suggest that genetic variants in the 8 candidate genes coding for chemotactic cytokines have little influence in the risk of breast cancer in postmenopausal women. Additional examination of the relationship between CXCL12 rs1801157 and breast cancer risk is warranted.

Abstract
Genital infection with the oncogenic human papillomavirus is the necessary cause of cervical cancer and of a large fraction of vulvar cancers. The toll-like receptor and the nuclear factor κB (NF-κB) signaling pathways have been implicated in inflammation, autoimmune disease and cancer, but whether common nucleotide variation in these pathways is associated with the risk of cervical and vulvar cancers has received little study. Using data from a population-based case-control study of cervical and vulvar cancers, we genotyped 205 single nucleotide polymorphisms (SNPs) in and around 32 candidate gene regions within these pathways. Gene-based analyses were used to estimate the associations between individual gene regions and the risk of cervical and vulvar cancers. Odds ratio (OR) and 95% confidence intervals (CI) were calculated to assess the risk of cervical and vulvar cancers for each SNP. p-Values were adjusted for multiple testing. A total of 876 cervical cancer cases, 517 vulvar cancer cases and 1,100 controls were included in the analysis. The TNF region was significantly associated with the risks of cervical cancer (gene-based p-value: 2.0 × 10(-4) ) and vulvar cancer (gene-based p-value: 1.0 × 10(-4) ). The rare allele (A) of SNP rs2239704 in the 5' UTR of the LTA gene was significantly associated with increased risks of cervical cancer (OR=1.31, 95% CI: 1.15-1.50; adjusted p-value: 0.013) and vulvar cancer (OR=1.51, 95% CI: 1.30-1.75; adjusted p-value: 1.9 × 10(-5) ). These findings add to the evidence of the importance of the immune system in the etiology of cervical and vulvar cancers.

Abstract
Background Toll-like receptors (TLRs) and the transcription factor nuclear factor-κB (NFκB) are important in inflammation and cancer. Methods We examined the association between breast cancer risk and 233 tagging single nucleotide polymorphisms within 31 candidate genes involved in TLR or NFκB pathways. This population-based study in the Seattle area included 845 invasive breast cancer cases, diagnosed between 1997 and 1999, and 807 controls aged 65–79. Results Variant alleles in four genes were associated with breast cancer risk based on gene-level tests: MAP3K1, MMP9, TANK, and TLR9. These results were similar when the risk of breast cancer was examined within ductal and luminal subtypes. Subsequent exploratory pathway analyses using the GRASS algorithm found no associations for genes in TLR or NFκB pathways. Using publicly available CGEMS GWAS data to validate significant findings (N = 1,145 cases, N = 1,142 controls), rs889312 near MAP3K1 was confirmed to be associated with breast cancer risk (P = 0.04, OR 1.15, 95% CI 1.01–1.30). Further, two SNPs in TANK that were significant in our data, rs17705608 (P = 0.05) and rs7309 (P = 0.04), had similar risk estimates in the CGEMS data (rs17705608 OR 0.83, 95% CI 0.72–0.96; CGEMS OR 0.90, 95% CI 0.80–1.01 and rs7309 OR 0.83, 95% CI 0.73–0.95; CGEMS OR 0.91, 95% CI 0.81–1.02). Conclusions Our findings suggest plausible associations between breast cancer risk and genes in TLR or NFκB pathways. Given the few suggestive associations in our data and the compelling biologic rationale for an association between genetic variation in these pathways and breast cancer risk, further studies are warranted that examine these effects.

Abstract
Given the important role of cell mediated immunity in viral clearance and control of premalignant lesions, we hypothesize that variation in the IL-12/IL-10 cytokine and cytokine receptor genes may influence cervical and vulvar cancer risk. We evaluated 76 tagSNPs from seven candidate genes (IL-10, IL-12A, IL-12B, IL-10RA, IL-10RB, IL-12RB1, and IL12RB2) in case-parent sets (n=43 cervical squamous cell carcinoma (SCC), n=96 cervical adenocarcinoma, n=53 vulvar SCC), additional cases (n=356 cervical SCC, n=406 cervical adenocarcinoma, and n=473 vulvar SCC) and population based controls (1,111). We calculated log-additive odds ratios (ORs) and 95% confidence intervals (CIs) for the association between tagSNP and cancer risk using a pseudo-likelihood based method which combined genotype information on cases, parents, and population controls. After correction for multiple comparisons, we identified several statistically significant SNP associations. Cervical SCC risk was associated with the minor alleles of the IL10RA rs9610 3' UTR SNP (OR=1.76, 95% CI=1.15-2.68) and two synonymous IL12RB2 SNPs (rs4297265, OR=0.46, 95% CI=0.26-0.82; rs2229546, OR=0.43, 95% CI=0.21-0.87). Cervical adenocarcinoma risk was associated with the minor alleles of the IL10RA rs4252314 intronic SNP (OR=2.23, 95% CI=1.26-3.96) and IL12RB1 rs11575934 non-synonymous SNP (OR=1.51, 95% CI=1.12-2.05). Finally, the minor allele of the IL12B rs3181224 3' UTR SNP was associated with a reduced risk of vulvar SCC (OR=0.30, 95% CI=0.12-0.74). These results raise the possibility that a shift in the balance of the immune response due to genetic variants in key cytokine genes could influence the development of cervical and vulvar cancer.

Abstract
Background
Corticosteroid use is associated with increased risk of anal neoplasia in transplant patients. We investigated the relationship between these medications, indications for their use, and risk of anal neoplasia in the general population. Methods: Men (n = 119) and women (n = 187) diagnosed with anal carcinoma in situ or anal cancer (AC) in the Seattle area (1986–2004) were compared with controls (n = 239 men and n = 1445 women), matched for sex and age. In-person interviews included questions about medical history and medications used for >6 months. Odds ratios (OR), and 95% confidence intervals (CI), were used to approximate the relative risk and adjusted for age, smoking, and number of partners. Results: AC was associated with corticosteroid use for women (OR 2.4, 95% CI 1.5–3.9) but not men (OR 1.4, 95% CI 0.5–4.0). We also investigated conditions associated with corticosteroids including diabetes, asthma, sinusitis, chronic kidney disease, and arthritis. Two immune-related conditions were associated with increased risk of AC in women but not men, specifically chronic kidney disease (women: OR 5.8, 95% CI 2.3–14.9; men: OR 1.0) and arthritis (women: OR 2.8, 95% CI 1.4–5.4; men: OR 0.3, 95% CI 0.1–1.7). Conclusions: Our population-based study suggests that women who use corticosteroids or have immune-related conditions may be at increased risk of AC. Future studies that examine dose and duration of corticosteroid use are needed to confirm these findings. As screening guidelines for anal neoplasia develop, consideration of women with a history of indications for immune suppression are warranted.

Abstract
The Skin Cancer after Organ Transplant (SCOT) study was designed to investigate the link between genus beta human papillomavirus (HPV) and squamous cell skin cancer (SCSC). We focused on a population receiving immunosuppressive therapy for extended periods, transplant patients, as they are at extremely high risk for developing SCSC. Two complementary projects were conducted in the Seattle area: (i) a retrospective cohort with interview data from 2004 recipients of renal or cardiac transplants between 1995 and 2010 and (ii) a prospective cohort with interview data from 328 people on the transplant waiting lists between 2009 and 2011. Within the retrospective cohort, we developed a nested case-control study (172 cases and 337 control subjects) to assess risk of SCSC associated with markers of HPV in SCSC tumour tissue and eyebrow hair bulb DNA (HPV genotypes) and blood (HPV antibodies). In the prospective cohort, 135 participants had a 1-year post-transplant visit and 71 completed a 2-year post-transplant visit. In both arms of the cohort, we collected samples to assess markers of HPV infection such as acquisition of new types, proportion positive for each type, persistence of types at consecutive visits and number of HPV types detected. In the prospective cohort, we will also examine these HPV markers in relation to levels of cell-mediated immunity. The goal of the SCOT study is to use the data we collected to gain a more complete understanding of the role of immune suppression in HPV kinetics and of genus beta HPV types in SCSC.

Abstract
OBJECTIVES The CD83 glycoprotein is a marker of dendritic cell maturation that may contribute to the T cell response to oncogenic human papillomavirus (HPV) infection. Whether single nucleotide polymorphisms (SNPs) in CD83 influence the risk of HPV-related genital cancers has not been adequately studied. We investigated whether the common genetic variation of the CD83 region was associated with the risks of cervical and vulvar cancers in a population-based case-control study conducted in the Seattle-Puget Sound Region. METHODS A total of 17 tagSNPs were genotyped in the CD83 region of 886 cervical cases, 517 vulvar cases and 1100 controls. Odds ratio (OR) and 95% confidence intervals (CI) were computed to assess the risk of cervical and vulvar cancers. The interaction between the tagSNPs and cigarette smoking was also explored. RESULTS TagSNPs in the CD83 chromosomal region were not associated with risk of either cervical or vulvar cancer. TagSNP rs853360 was associated with a decreased risk of cervical squamous cell carcinoma (SCC) (OR=0.80; 95% CI: 0.66-0.98). CONCLUSIONS Our results do not suggest that the common genetic variation of CD83 is related to cervical or vulvar cancers. The association between tagSNP rs853360 and risk of cervical SCC is likely to be due to chance. If larger or pooled studies confirm our results, CD83 has little or no influence in the risk of HPV-related cancers.

Abstract
The purpose of this study was to determine whether endurance (E) or endurance + resistance (ER) training affects C-reactive protein (CRP) and if these changes are related to alterations in fitness and (or) body composition in young females. Thirty-eight females (aged 18-24 years) were assigned to 1 of 3 groups: (1) E, (2) ER or (3) active control (AC). The E and ER groups completed 15 weeks of marathon training. The ER group performed additional resistance training and the AC group maintained their usual exercise routine. Primary outcomes were measured pre- and post-training and included anthropometric indices, dual-energy x-ray absorptiometry, plasma CRP, time to complete 1.5 miles (in minutes), and upper and lower body strength tests (i.e., 8 repetition max on bench and leg press (ER group only)). There were no differences in any variable among the groups at baseline. After training, the E group decreased time to complete 1.5 miles (p < 0.05). The AC group decreased percent and absolute body fat while the E group decreased percent body fat, absolute body fat, and android and gynoid body fat (p < 0.05). The ER group significantly improved strength (p < 0.001) and reduced plasma CRP from 2.0 ± 1.1 to 0.8 ± 0.3 mg·L(-1) (p = 0.03). No significant associations were observed between CRP and measures of body composition or aerobic capacity. Combined endurance and resistance training may be an effective modality for reducing plasma CRP in young adult females independent of changes in aerobic capacity or body composition.

Abstract
Proinflammatory cytokines are associated with age-related diseases including arthritis and heart disease. IL6 and TNF also play key roles in estrogen modulation in older women. We explored whether variation in IL6 and TNF genes influenced the risk of breast cancer in samples that differed by age group: <44 years (228 cases and 271 controls), 45-64 years (426 cases and 396 controls), and 65+ years (228 cases and 239 controls). Samples were drawn from population-based case-control studies conducted in Seattle. Age-adjusted odds ratios (ORs) were calculated to evaluate the risk associated with variants in IL6, IL6R, TNF, and TNFRSF1A. There was a significantly increased risk of breast cancer associated with one or more C>T alleles at IL6 rs2069861 among subjects in the oldest age group (OR 1.8, 95% CI 1.1-2.9), but no overall increased risk of breast cancer associated with any IL6 or IL6R variants in the combined data. There were significantly elevated risks of breast cancer among women 45-64 years old associated with a UTR 5' flanking SNP LTA rs2009658 C>G allele (OR 1.5, 95% CI 1.1-1.9) and a nonsynonomous coding SNP TNFRSF1A rs767455 T>C allele (OR 1.3, 95% CI 1.1-1.6); these two variants were also elevated in the combined data (OR 1.3, 95% CI 1.1-1.5 and OR 1.2, 95% CI 1.1-1.4, respectively). This study supports a modest association between a variant in IL6 and breast cancer among older women and TNF-related variants and breast cancer among middle-aged women. Further evaluation of these genes in other studies is warranted.

Abstract
Abstract
Syndecans are transmembrane proteins on the cell surface that act as receptors for ligands from a number of protein families. These proteoglycans are involved in a large number of important normal cell functions, including signaling, proliferation, and cell-matrix adhesion; they are also involved in aberrant cell functions such as inflammation, angiogenesis, and carcinogenesis. In a recent pathway directed re-analysis of GWAS data (Menashe, Cancer Research, 2010), variants in the syndecan-1 (SDC1) gene on chromosome 2p were found to be associated with excess risk of breast cancer. We sought to extend this finding by investigating the association between tagging SNPs in the SDC1 gene and risk of breast cancer in our case-control study (The PACE study) in older women. This population-based study includes 845 women who were 65-79 years old at diagnosis of incident breast cancer and 807 age-matched unaffected controls from the Seattle area. The analysis was restricted to Caucasian women. A total of 11 SNPs were chosen to represent 10 bins using Snagger, with double coverage of one large bin. Five SNPs failed genotyping, leaving six SNPs for analysis. At the gene level, a P-min permutation test was not significant for SDC1 (p=0.10). Three SNPs, rs10495704, rs2002090, and rs3771240, were in high linkage disequilibrium in our controls (r2 0.81-0.87) and all three were separately associated with marginally increased risks of breast cancer (OR 1.2, 95% CI 1.0-1.4). One of these SNPs, rs10495704, is in the 5’UTR and thus could be associated with protein processing. No excess risk of breast cancer was associated with the other three SDC1 variants: rs4432408, rs2348478, or rs2015110. A similar pattern of marginally increased risk for the three polymorphisms in high LD (rs10495704, rs2002090, and rs3771240) was found in two subsequent analyses restricted to women with ductal histology and luminal type tumors. We are currently assessing other genes related to inflammation that may be related to breast cancer risk in this study population. The data for SDC1 in the PACE study cannot rule out a modest association with breast cancer risk.

Abstract
BACKGROUND Human papillomavirus is the acknowledged cause of cervical cancer. We hypothesized that allergies, characterized by hyperimmune reaction to common allergens and which have been associated with various cancers, may be related to cervical cancer, and that genetic variation in cytokine genes related to allergies might impact cervical cancer risk. METHODS We investigated the risk of invasive squamous cell cervical cancer (SCC) associated with self-reported allergies and with variation in allergy-related cytokine genes using data from a case-control study (561 cases, 1,258 controls) conducted in Washington State. Logistic regression models yielded odds ratios (OR) and 95% CI. RESULTS Pollen allergy, the most commonly reported allergy, was associated with reduced SCC risk (OR: 0.6; 95% CI: 0.5-0.8). Of 60 tagging single-nucleotide polymorphisms covering eight genes (CSF2, IL3, IL4, IL13, CSF2RB, IL4R, IL13RA1, IL13RA2), several were related to pollen allergies among controls: IL4R rs3024647 (dominant OR: 1.5; 95% CI: 1.0-2.3; P = 0.04), CSF2RB rs16997517 (dominant OR: 2.2; 95% CI: 1.0-4.7; P = 0.04), and IL13 rs1800925 (per-allele OR: 1.7; 95% CI: 1.3-2.4; P = 0.0007). Two variants were inversely associated with SCC risk: IL4R rs3024656 (per-allele OR: 0.8; 95% CI: 0.6-1.0; P = 0.03) and CSF2RB rs16997517 (dominant OR: 0.4; 95% CI: 0.2-0.9; P = 0.04). CONCLUSIONS Pollen allergies were related to reduced SCC risk. CSF2RB rs16997517 was directly related to pollen allergies in controls and to reduced SCC risk. IMPACT If other studies confirm these results, the mechanism behind allergy-associated immune response associated with SCC risk may be worth exploring in the context of therapeutic or prophylactic vaccines.

Abstract
Merkel cell polyomavirus (MCPyV) is a common infectious agent that is likely involved in the etiology of most Merkel cell carcinomas (MCC). Serum antibodies recognizing the MCPyV capsid protein VP1 are detectable at high titer in nearly all MCC patients and remain stable over time. Although antibodies to the viral capsid indicate prior MCPyV infection, they provide limited clinical insight into MCC because they are also detected in more than half of the general population. We investigated whether antibodies recognizing MCPyV large and small tumor-associated antigens (T-Ag) would be more specifically associated with MCC. Among 530 population control subjects, these antibodies were present in only 0.9% and were of low titer. In contrast, among 205 MCC cases, 40.5% had serum IgG antibodies that recognize a portion of T-Ag shared between small and large T-Ags. Among cases, titers of T-Ag antibodies fell rapidly (∼8-fold per year) in patients whose cancer did not recur, whereas they rose rapidly in those with progressive disease. Importantly, in several patients who developed metastases, the rise in T-Ag titer preceded clinical detection of disease spread. These results suggest that antibodies recognizing T-Ag are relatively specifically associated with MCC, do not effectively protect against disease progression, and may serve as a clinically useful indicator of disease status.

Abstract
CXCL12 provides a chemotactic signal-directing leucocyte migration and regulates metastatic behaviour of tumour cells. We conducted a population-based case-control study to test the hypothesis that common genetic variation in CXCL12 individual single nucleotide polymorphism (SNP) alleles and haplotypes] is associated with the risk of cervical carcinoma. Cases (n = 917) were residents of western Washington State diagnosed with invasive squamous cell cervical carcinoma (SCC), invasive adenocarcinoma or adenosquamous carcinoma, or adenocarcinoma in situ of the cervix. Control participants (n = 849) were identified from the source population by random digit telephone dialling and frequency matched to cases on county and age. Nine CXCL12 tagSNPs chosen from the SeattleSNPs database were genotyped. The minor allele of intronic SNP rs266085 was inversely associated with cervical cancer under a recessive genetic effects model (OR = 0.74, 95% CI: 0.56-0.98). Among the ten common haplotypes inferred from the nine tagSNPs, one haplotype defined by minor alleles at 5'-flanking SNP rs17885289 and rs266085, and common alleles at the other seven SNPs occurred among 7.8% of cases and 10.6% of controls (dominant model OR = 0.72, 95% CI: 0.56-0.93; recessive model OR = 0.35, 95% CI: 0.12-0.97; and log-additive model OR = 0.72, 95% CI: 0.57-0.90). A stepwise procedure identified rs17885289, rs266085 and 3'-untranslated region (UTR) SNP rs266093 as the most parsimonious subset of SNPs necessary to define the haplotype inversely associated with cervical cancer risk in our study. A 3'-UTR SNP, rs1801157, previously found to be related to HIV pathogenesis, was not associated with cervical cancer risk. Further population-based studies are warranted to confirm these associations between genetic variation in CXCL12 and cervical cancer risk.

Abstract
BACKGROUND Merkel cell polyomavirus (MCPyV) has been detected in approximately 75% of patients with the rare skin cancer Merkel cell carcinoma. We investigated the prevalence of antibodies against MCPyV in the general population and the association between these antibodies and Merkel cell carcinoma. METHODS Multiplex antibody-binding assays were used to assess levels of antibodies against polyomaviruses in plasma. MCPyV VP1 antibody levels were determined in plasma from 41 patients with Merkel cell carcinoma and 76 matched control subjects. MCPyV DNA was detected in tumor tissue specimens by quantitative polymerase chain reaction. Seroprevalence of polyomavirus-specific antibodies was determined in 451 control subjects. MCPyV strain-specific antibody recognition was investigated by replacing coding sequences from MCPyV strain 350 with those from MCPyV strain w162. RESULTS We found that 36 (88%) of 41 patients with Merkel cell carcinoma carried antibodies against VP1 from MCPyV w162 compared with 40 (53%) of the 76 control subjects (odds ratio adjusted for age and sex = 6.6, 95% confidence interval [CI] = 2.3 to 18.8). MCPyV DNA was detectable in 24 (77%) of the 31 Merkel cell carcinoma tumors available, with 22 (92%) of these 24 patients also carrying antibodies against MCPyV. Among 451 control subjects from the general population, prevalence of antibodies against human polyomaviruses was 92% (95% CI = 89% to 94%) for BK virus, 45% (95% CI = 40% to 50%) for JC virus, 98% (95% CI = 96% to 99%) for WU polyomavirus, 90% (95% CI = 87% to 93%) for KI polyomavirus, and 59% (95% CI = 55% to 64%) for MCPyV. Few case patients had reactivity against MCPyV strain 350; however, indistinguishable reactivities were found with VP1 from strain 350 carrying a double mutation (residues 288 and 316) and VP1 from strain w162. CONCLUSION Infection with MCPyV is common in the general population. MCPyV, but not other human polyomaviruses, appears to be associated with Merkel cell carcinoma.

Abstract
The objective of this study was to examine the association of self-reported physical activity (PA) with body composition in 290 college students (49% male, 60% White) 18-25 years of age. Outcome measures included: self-reported PA levels calculated in MET-hrs·wk-1 from the International Physical Activity Questionnaire (IPAQ); body mass index (BMI; in kg·m-2); and body composition variables estimated by dual-energy X-ray absorptiometry (DXA). Mean activity levels of the sample were 39.8 ± 23.8 MET-hrs·wk-1. Participants were divided into quartiles of PA levels: ≥0 to <24.0, ≥24.0 to <34.0, ≥34.0 to <51.25, and ≥51.25 MET-hrs ·wk-1 and body composition variables were compared by group. Chi-square analyses revealed a significant difference for gender by PA quartile [χ2 (3, N=290) = 32.42, p < 0.0001], and for gender by race by PA quartile [χ2 (9, N=290) = 37.82, p < 0.0001]. MET-hrs·wk-1 was inversely correlated with %BF (r = -0.40, p < 0.0001) but not BMI (r = 0.05, p = 0.43). When comparing body composition variables across PA quartiles, no significant differences were observed for BMI; however, subjects in the highest quartile of PA had a lower percent body fat (%BF) and fat mass (FM), and a higher lean-tissue mass (LTM) compared to subjects in the other three groups. In this cohort of young adults, participants in the highest activity group had a more fit body composition profile (e.g., lower %BF, lower FM, and higher LTM) which was not reflected in BMI and was independent of gender and race.

Abstract
BACKGROUND Given the established links among young age at first intercourse (AFI), number of sex partners, high-risk human papillomavirus infection, and squamous cell cervical cancer (SCC), we hypothesized that women diagnosed with SCC at younger ages would be more likely to report young AFI than women diagnosed later in life. METHODS We performed a population-based investigation among invasive SCC cases who were diagnosed between 1986 and 2004, were ages 22 to 53 years, and lived in the metropolitan Seattle-Puget Sound region (n = 333). Using multivariate linear regression, we estimated coefficients and 95% confidence intervals (95% CI) to assess the association between age at SCC diagnosis and AFI (<15, 15-18, > or =19 years) and number of sex partners at age <20 years (0, 1, 2-4, 5-14, > or =15), accounting for birth year and other factors. Interactions were assessed using the likelihood ratio test. RESULTS The interval between AFI and SCC diagnosis ranged from 4 to 35 years. In a multivariate model, compared with SCC cases reporting AFI > or =19, the mean age of diagnosis was 3.1 years younger for SCC cases reporting AFI <15 (95% CI, -5.8 to -0.5) and 2.6 years younger for SCC cases reporting AFI 15 to 18 (95% CI, -4.6 to -0.6). Although number of sex partners at age <20 years was associated with age at SCC diagnosis in a crude analysis, the association was not independent of AFI. However, in the AFI > or =19 and <15 groups, differences in effect were seen by number of sex partners at age <20 years (P(interaction) = 0.08), with the association remaining strong and significant only in the AFI <15 group that had > or =2 partners at age <20 years (coefficient, -4.2; 95% CI, -6.3 to -2.1). CONCLUSION Among younger and middle-aged women with SCC, early age of diagnosis was associated with early AFI, although the effect appeared to be modified by number of sex partners at age <20 years.

Abstract
Cigarette smoking is an established cofactor to human papillomavirus (HPV) in the development of cervical and vulvar squamous cell carcinoma (SCC), and may influence risk through an immunosuppressive pathway. Genetic variation in interleukin 2 (IL2), associated in some studies with the inhibition of HPV-targeted immunity, may modify the effect of smoking on the risk of HPV-related anogenital cancers. We conducted a population-based case-only study to measure the departure from a multiplicative joint effect of cigarette smoking and IL2 variation on cervical and vulvar SCC. Genotyping of the four IL2 tagSNPs (rs2069762, rs2069763, rs2069777, and rs2069778) was done in 399 cervical and 486 vulvar SCC cases who had been interviewed regarding their smoking history. Compared with cases carrying the rs2069762 TT genotype, we observed significant departures from multiplicativity for smoking and carriership of the TG or GG genotypes in vulvar SCC risk [interaction odds ratio (IOR), 1.67; 95% confidence interval (CI), 1.16-2.41]. Carriership of one of three diplotypes, together with cigarette smoking, was associated with either a supramultiplicative (TGCT/GGCC; IOR, 2.09; 95% CI, 0.98-4.46) or submultiplicative (TTCC/TGTC; IOR, 0.37; 95% CI, 0.16-0.85 or TGCT/TGCC; IOR, 0.37; 95% CI, 0.15-0.87) joint effect in vulvar cancer risk. For cervical SCC, departure from multiplicativity was observed for smokers homozygous for the rs2069763 variant allele (TT versus GG or GT genotypes; IOR, 1.87; 95% CI, 1.00-3.48), and for carriership of the TTCC/TTCC diplotype (IOR, 2.08; 95% CI, 1.01-4.30). These results suggest that cervical and vulvar SCC risk among cigarette smokers is modified by genetic variation in IL2.

Abstract
OBJECTIVES To describe prevalence and estimated attribution of human papillomavirus (HPV) types in U.S. cervical, vaginal, and vulvar precancers and cancers. METHODS U.S. studies reporting HPV typing for cervical intraepithelial neoplasia (CIN), vulvar intraepithelial neoplasia (VIN), and vaginal intraepithelial neoplasia (VaIN) and/or invasive cancers of those sites were gathered from the PubMed database (http://www.ncbi.nlm.nih.gov/sites/entrez/). Selected studies had PCR testing data for > or =10 cases for a disease endpoint. Analytic methods augmented prior reviews of cervical disease with an updated and expanded analysis (including vulvar and vaginal disease), new selection criteria for specimens, and adjustment for histologic type, where possible, among pooled cancer cases. In addition, for analyses of estimated attribution of HPV types, we incorporated accounting methods for lesions infected with multiple HPV types. RESULTS Data from 22 U.S. studies meeting review eligibility criteria were tabulated. Following adjustment for the presence of multiple HPV types in a single specimen, the top two HPV types contributing to disease were CIN 1 (HPV 16/66; 15.3%), CIN 2/3 (HPV 16/31; 61.9%), cervical cancer (HPV 16/18; 79.2%), VIN 1 (HPV 6/11; 41.7%), VIN 3 (HPV 16/18; 84.0%), vulvar cancer (HPV 16/33; 55.5%), VaIN 3 (HPV 16/18; 65.1%), and vaginal cancer (HPV 16/18; 72.7%). CONCLUSIONS The HPV type distribution and proportion of cases testing positive for any HPV type were observed to vary among U.S. cervical, vulvar, and vaginal neoplasias and by grade of disease. Adjustment for the presence of multitype HPV infections can have an important effect on the estimated attribution of HPV types to disease, particularly for types other than HPV 16.

Abstract
Infection with 1 of approximately 15 oncogenic human papillomaviruses is known to be linked to the development of all histologic forms of cervical cancer. We evaluated whether polymorphisms in syndecan-1 (SDC-1), a gene whose protein product is believed to be involved in human papillomavirus entry into epithelial cells, were associated with histologic subtypes of cervical cancer. A total of 293 in situ/invasive adenocarcinoma cases, 260 in situ/invasive squamous cell carcinoma cases, and 478 controls from two studies conducted in the Eastern United States and Seattle area were evaluated. DNA from peripheral blood was used for testing. We sequenced 5 exons and 60 nucleotides upstream of the start codon for SDC-1 in a random subset of 50 cases and 50 controls from the Eastern U.S. Study and identified two polymorphisms (E84E, rs2230924 and Pro-27 C --> T, rs11544860). PCR-based testing was done to evaluate risk associated with these two polymorphisms. Polymorphisms of SDC-1 were not associated with risk of squamous cell carcinomas of the cervix. Similarly, there was no evidence for an association between SDC-1 exon 3 polymorphisms and risk of cervical adenocarcinomas. A marginally significant increase in risk of cervical adenocarcinoma was associated with the presence of the Pro-27 polymorphism (pooled odds ratios, 1.6; 95% confidence intervals, 0.99-2.6), an effect that was restricted to the Eastern U.S. Study. Our results indicate a lack of association between SDC-1 polymorphisms and risk of squamous cell carcinomas of the cervix. An association between SDC-1 Pro-27 polymorphism and cervical adenocarcinoma cannot be ruled out.

Abstract
Variation in human major histocompatibility genes may influence the risk of squamous cell cervical cancer (SCC) by altering the efficiency of the T-cell-mediated immune response to human papillomavirus (HPV) antigens. We used high-resolution methods to genotype human leukocyte antigen (HLA) class I (A, B, and Cw) and class II (DRB1 and DQB1) loci in 544 women with SCC and 542 controls. Recognizing that HLA molecules are codominantly expressed, we focused on co-occurring alleles. Among 137 allele combinations present at >5% in the case or control groups, 36 were significantly associated with SCC risk. All but one of the 30 combinations that increased risk included DQB1*0301, and 23 included subsets of A*0201-B*4402-Cw*0501-DRB1*0401-DQB1*0301. Another combination, B*4402-DRB1*1101-DQB1*0301, conferred a strong risk of SCC (odds ratio, 10.0; 95% confidence interval, 3.0-33.3). Among the six combinations that conferred a decreased risk of SCC, four included Cw*0701 or DQB1*02. Most multilocus results were similar for SCC that contained HPV16; a notable exception was A*0101-B*0801-Cw*0701-DRB1*0301-DQB1*0201 and its subsets, which were associated with HPV16-positive SCC (odds ratio, 0.5; 95% confidence interval, 0.3-0.9). The main multilocus associations were replicated in studies of cervical adenocarcinoma and vulvar cancer. These data confirm that T helper and cytotoxic T-cell responses are both important cofactors with HPV in cervical cancer etiology and indicate that co-occurring HLA alleles across loci seem to be more important than individual alleles. Thus, certain co-occurring alleles may be markers of disease risk that have clinical value as biomarkers for targeted screening or development of new therapies.

Abstract
Human papillomavirus (HPV) is the central etiologic factor for cervical cancer, and prior studies suggested C. trachomatis may act as an HPV cofactor. We examined the C. trachomatis-cervical cancer association by serotype, histology, HPV type in the tumor, and other HPV cofactors. We conducted a population-based study in the Seattle-Puget Sound area of 302 women with invasive squamous cell carcinomas (SCC), 185 women with adenocarcinomas of the cervix (AC), and 318 HPV seropositive control women. The risk of SCC associated with antibodies to C. trachomatis was increased (OR 1.6, 95% CI 1.1-2.2) but not for AC (OR 1.0, 95% CI 0.6-1.5). This association was independent of HPV type in the SCC tumor tissue. There was an association between specific serotypes of C. trachomatis and SCC for 6 of the 10 serotypes: B (OR 3.6, 95% CI 1.5-8.4), D (OR 2.1, 95% CI, 1.2-3.5), E (OR 2.4, 95% CI, 1.4-3.9), G (OR 3.0, 95% CI, 1.1-7.9), I (OR 4.2, 95% CI, 1.5-11.7), and J (OR 2.3, 95% CI, 1.0-5.1), but not for the 4 types (C, F, H, and K) that were present at very low prevalence in this population. There was an increased risk of SCC, but not AC, associated with antibodies to C. trachomatis that was not serotype specific.

Abstract
Exercise elicits intensity-dependent increases in epinephrine (Epi), norepinephrine (NE), cortisol (CORT), and lactate (Lac), whereas at rest the hormonal responses to mental stress include increases in Epi, NE, and CORT, but not Lac. Additionally, elevations in CORT at rest are associated with negative affect. Finally, as exercise intensity increases, perceptions of effort (RPE) increase and affect becomes more negative. The purpose of this study was to examine the responses of Epi, NE, CORT, Lac, RPE, and affect during incremental increases in exercise to maximum. Seven highly-trained male runners completed a discontinuous treadmill protocol that included 10 minutes at 60%, 10 minutes at 75%, 5 minutes at 90%, and 2 minutes at 100% of VO2max. Blood samples were collected through an intravenous catheter before, during, and following exercise during the experimental condition, and during a time-matched control condition. RPE and affect were assessed just prior to each blood draw. The Epi, NE, CORT, and Lac displayed the expected incremental increases, however affect became more negative at higher exercise intensities, and RPE increased as exercise intensity increased. Data suggest that CORT follows the same pattern of response to graded exercise as affect. Since perceptual and affective responses to exercise are associated with motivation, these documented negative affective shifts during exercise should be considered in order to develop strategies that lead to enhanced exercise adherence and performance.

Abstract
Lentivirus-based gene transfer has the potential to efficiently deliver DNA-based therapies into non-dividing epithelial cells of the airway for the treatment of lung diseases such as cystic fibrosis. However, significant barriers both to lung-specific gene transfer and to production of lentivirus vectors must be overcome before these vectors can be routinely used for applications to the lung. In this study, we investigated whether the ability to produce lentiviral vectors pseudotyped with fowl plague virus hemagglutinin (HA) could be improved by co-expression of influenza virus M2 in vector-producing cells. We found that M2 expression led to a 10-30-fold increase in production of HA-pseudotyped lentivirus vectors based upon equine infectious anemia virus (EIAV) or human immunodeficiency virus type 1 (HIV-1). Experiments using the M2 inhibitor amantadine and a drug-resistant mutant of M2 established that the ion channel activity of M2 was important for M2-dependent augmentation of vector production. Furthermore, the neuraminidase activity necessary for particle release from producer cells could also be incorporated into producer cells by co-expression of influenza NA cDNA. Lentiviral vectors pseudotyped with influenza envelope proteins were able to efficiently transduce via the apical membrane of polarized mouse tracheal cultures in vitro as well as mouse tracheal epithelia in vivo.

Abstract
Few population-based case-control studies have assessed etiologic factors for penile cancer. Past infection with high-risk human papillomavirus (HPV) is a known risk factor for penile cancer; however, few previous studies have related the HPV DNA status of the tumor to potential demographic and behavioral risk factors for the disease or evaluated whether in situ and invasive penile cancer share risk factors. Little information is available on the role and timing of circumcision in the etiology of penile cancer. We conducted a population-based case-control study in western Washington state that included 137 men diagnosed with in situ (n = 75) or invasive (n = 62) penile cancer between January 1, 1979, and December 31, 1998, and 671 control men identified through random digit dialing. Cases and controls were interviewed in person and provided peripheral blood samples. Case and control blood samples were tested for antibodies to HPV16 and HSV-2, and tumor specimens from cases were tested for HPV DNA. Men not circumcised during childhood were at increased risk of invasive (OR = 2.3, 95% CI 1.3-4.1) but not in situ (OR = 1.1, 95% CI 0.6-1.8) penile cancer. Approximately 35% of men with penile cancer who had not been circumcised in childhood reported a history of phimosis compared to 7.6% of controls (OR = 7.4, 95% CI 3.7-15.0). Penile conditions such as tear, rash and injury were associated with increased risk of disease. Among men not circumcised in childhood, phimosis was strongly associated with development of invasive penile cancer (OR = 11.4, 95% CI 5.0-25.9). When we restricted our analysis to men who did not have phimosis, the risk of invasive penile cancer associated with not having been circumcised in childhood was not elevated (OR = 0.5, 95% CI 0.1-2.5). Cigarette smoking was associated with a 4.5-fold risk (95% CI 2.0-10.1) of invasive penile cancer. HPV DNA was detected in 79.8% of tumor specimens, and 69.1% of tumors were HPV16-positive. The proportion of HPV DNA-positive tumors did not vary by any risk factors evaluated. Many risk factors were common for both in situ and invasive disease. However, 3 factors that did not increase the risk for in situ cancer proved significant risk factors for invasive penile cancer: lack of circumcision during childhood, phimosis and cigarette smoking. The high percentage of HPV DNA-positive tumors in our study is consistent with a strong association between HPV infection and the development of penile cancer regardless of circumcision status. Circumcision in early childhood may help prevent penile cancer by eliminating phimosis, a significant risk factor for the disease.

Abstract
BACKGROUND Anal cancer is a rare malignancy of the anogenital tract that historically has affected women at a greater rate than men. METHODS The authors analyzed changing trends in incidence rates and 5-year relative survival percentages for patients with anal cancer. The publicly available data used in the current study were obtained from the Surveillance, Epidemiology, and End Results (SEER) Program, a system of population-based tumor registries in the United States. RESULTS The incidence of anal cancer was similar for men and women between 1994 and 2000 (2.04 per 100,000 and 2.06 per 100,000, respectively), the most recent period for which data were available, whereas men had lower rates than did women between 1973 and 1979 (1.06 per 100,000, compared with 1.39 per 100,000), the earliest period for which data were available. In addition, recently, black men had higher incidence rates than did other race-specific and gender-specific groups (2.71 per 100,000). From the earliest period for which data were available to the most recent period, relative 5-year survival improved from 59% to 73% among women, was unchanged among men ( approximately 60%), and decreased from 45% to 27% among black men. Eighteen percent of patients who had distant disease were alive at 5 years, compared with 78% of patients who had localized disease. CONCLUSIONS The incidence of anal cancer in the United States increased between 1973 and 2000, particularly among men. There were higher incidence rates and lower survival rates for black men compared with other race-specific and gender-specific groups. Later disease stage was inversely associated with the survival rate, indicating that earlier detection may improve the survival of patients with anal cancer.

From the earliest period for which data were available to the most recent period, relative 5-year survival improved from 59% to 73% among women, was unchanged among men ( approximately 60%), and decreased from 45% to 27% among black men. Eighteen percent of patients who had distant disease were alive at 5 years, compared with 78% of patients who had localized disease. CONCLUSIONS The incidence of anal cancer in the United States increased between 1973 and 2000, particularly among men. There were higher incidence rates and lower survival rates for black men compared with other race-specific and gender-specific groups. Later disease stage was inversely associated with the survival rate, indicating that earlier detection may improve the survival of patients with anal cancer.

Abstract
BACKGROUND Anal cancer is a rare malignancy of the anogenital tract that historically has affected women at a greater rate than men. METHODS The authors analyzed changing trends in incidence rates and 5-year relative survival percentages for patients with anal cancer. The publicly available data used in the current study were obtained from the Surveillance, Epidemiology, and End Results (SEER) Program, a system of population-based tumor registries in the United States. RESULTS The incidence of anal cancer was similar for men and women between 1994 and 2000 (2.04 per 100,000 and 2.06 per 100,000, respectively), the most recent period for which data were available, whereas men had lower rates than did women between 1973 and 1979 (1.06 per 100,000, compared with 1.39 per 100,000), the earliest period for which data were available. In addition, recently, black men had higher incidence rates than did other race-specific and gender-specific groups (2.71 per 100,000). From the earliest period for which data were available to the most recent period, relative 5-year survival improved from 59% to 73% among women, was unchanged among men ( approximately 60%), and decreased from 45% to 27% among black men.

Abstract
OBJECTIVE A number of investigations have examined the effect of exercise on leptin concentrations, because leptin is associated with obesity, satiety, and reproductive function. High-intensity exercise is known to increase testosterone, an inhibitor of leptin. The objective of the study was to determine whether the leptin responses to a progressive, intermittent exercise protocol were related to serum testosterone concentrations. Most previous studies have examined leptin responses to low or moderately high exercise intensities. A second objective was to determine whether leptin responses were different than previous experiments using intermittent moderate and high-intensity exercise. METHODS Well-trained runners completed strenuous intermittent exercise consisting of treadmill running at 60, 75, 90, and 100% VO(2 max) and a subsequent resting control trial was also conducted. RESULTS There were significant increases in mean serum levels of leptin and testosterone with both quickly returning to baseline during recovery, but no relationship between the two hormones was found. After examining individual data for both hormones, it was discovered that subjects could be classified as leptin responders or nonresponders, whereas testosterone increased in all subjects. Responders had elevated serum leptin levels at baseline and exhibited increases after high-intensity exercise, whereas nonresponders did not show changes in leptin during exercise. CONCLUSIONS Data suggest testosterone levels do not acutely affect leptin responses to exercise or 1-h of recovery. Moreover, varied leptin responses to intense exercise in comparable well-trained runners was observed and was associated with baseline leptin concentrations.

Abstract
PURPOSE Adiponectin is a recently discovered adipocyte protein that is lower in patients with coronary artery disease and in Type II diabetics who have insulin resistance. Regular exercise is known to be a preventative factor in the development of atherosclerosis and Type II diabetes. Acute exercise increases insulin sensitivity; however, it also increases beta-adrenergic and glucocorticoid activities that may suppress adiponectin expression. Two experiments were conducted to determine whether acute exercise affects adiponectin concentrations. METHODS In the first experiment, six healthy male subjects completed 30 min of heavy continuous running exercise at 79% of VO (2max). In the second experiment, well-trained runners completed strenuous intermittent exercise consisting of treadmill running at 60, 75, 90, and 100% VO (2max). A resting control trial for the second experiment was also conducted. RESULTS Glucose and insulin were not altered significantly in the first experiment, but both increased significantly (P < 0.05) in the second experiment. A significant increase (P < 0.05) in adiponectin in the first experiment was no longer significant after correction for plasma volumes shifts. In the second experiment, there were significant (P < 0.05) changes in adiponectin concentrations over time but not a significant difference between adiponectin responses in exercise and control trials. CONCLUSIONS The data suggest that 30 min of heavy continuous running or more strenuous intermittent running does not stimulate an increase in production and release of adiponectin, and small increases in adiponectin concentrations resulting from the exercise may be attributed to normal plasma volume shifts.
