Abstract
Background Historically Black Colleges and Universities and Minority Serving Institutions are uniquely positioned to implement community-campus research partnerships based on a history of service, the pursuit of community trustworthiness and student demographics often similar to surrounding marginalized communities. The Morehouse School of Medicine Prevention Research Center collaborates with members of Historically Black Colleges and Universities, Minority Serving Institutes, and community organizations on the Community Engaged Course and Action Network. This network is the first of its kind and aims to strengthen members' ability to implement Community-Based Participatory Research (CBPR) principles and partnerships. Projects address public health priorities including mental health among communities of color, zoonotic disease prevention, and urban food deserts. Materials and methods To assess the effectiveness of the network, a Participatory Evaluation framework was implemented to conduct process evaluation which included review of partnership structures, operations, project implementation processes, and preliminary outcomes of the research collaborations. A focus group of Community Engagement Course and Action Network members (community and academic) was also conducted to identify benefits and challenges of the network with emphasis on key areas for improvement to further enhance the relationships between partners and to facilitate their subsequent community-campus research. Results Network improvements were tied to themes strengthening community-academic partnerships including sharing and fellowship, coalition building and collaboration, and greater connections and awareness of community needs through their current community-academic partnerships. The need to conduct ongoing evaluation during and after implementation, for determining the early adoption of CBPR approaches was also identified. Conclusion Evaluation of the network's processes, infrastructure, and operation provides early lessons learned to strengthen the network. Ongoing assessment is also essential for ensuring continuous quality improvement across partnerships such as determining CBPR fidelity, assessing partnership synergy, and dynamics, and for quality improvement of research protocol. The implications and potential for advancing implementation science through this and similar networks are great towards advancing leadership in modeling how foundations in community service can advance to CBPR partnership formation and ultimately, health equity approaches, that are local defined and assessed.

Abstract
Abstract
The US system has both considerable strengths and notable weaknesses. It has a large and well-trained health workforce, a wide range of high-quality medical specialists as well as secondary and tertiary institutions, a robust health sector research program, and, for selected services, among the best medical outcomes in the world. But it also suffers from incomplete coverage of its citizenry, health expenditures levels per person far exceeding all other countries, poor objective and subjective indicators of quality and outcomes, and an unequal distribution of resources and outcomes across the country and among different population groups. Because of the adoption of the Affordable Care Act in 2010, and subsequent revisions to it, the US is facing a period of enormous change. There is a great need to improve coverage and improve equity, better ensure quality outcomes, and find ways to better control expenditures.

Abstract
BACKGROUND Tapentadol may allow greater pain relief with reduced "opioid load" compared to oxycodone. Its use has not been studied in the obstetric population. The objective of this study was to compare the efficacy and side effect profile of tapentadol with oxycodone in patients who received spinal anesthesia for elective cesarean section. The trial was registered with EU Clinical Trials Register with CT number 2016-001621-33. METHODS This was a multicenter, randomized controlled trial. Randomized patients (n = 68) received either 50 mg tapentadol or oxycodone 10 mg 12 hourly postoperatively. The primary endpoint was the sum of pain intensity difference over the first 48 hours of treatment (SPID48). Secondary outcomes included time to rescue medications, SPID36, total pain relief (TOTPAR) scores, patient satisfaction scores, sum of total pain relief and pain intensity difference (SPRID) scores, time to rescue medications and side effects experienced. An analysis of covariance model with baseline pain intensity score as a covariate was used for statistical analysis. RESULTS There was no significant difference in the primary endpoint of SPID48 with adjusted mean difference -11.45 (95% CI -35.35, 12.45) p = .34). Oxycodone showed significantly greater SPID36 scores compared to tapentadol with increased time to rescue medication. Side effects experienced were similar between groups. CONCLUSION Tapentadol did not provide superior pain control or improved tolerability compared to oxycodone post cesarean section. Results should be interpreted however with consideration of administration of intrathecal opioids to all patients in this study and debate over the optimal dose of tapentadol for acute pain.

Abstract
Pregnant women and infants are at an increased risk of severe disease after influenza infection. Maternal immunization is a potent tool to protect both these at-risk groups. While the primary aim of maternal influenza vaccination is to protect the mother, a secondary benefit is the transfer of protective antibodies to the infant. A recent study using the tetanus, diphtheria and acellular pertussis (Tdap) vaccine indicated that children born to mothers immunized in the second trimester of pregnancy had the highest antibody titres compared to children immunized in the third trimester. The aim of the current study was to investigate how the timing of maternal influenza immunization impacts infant antibody levels at birth. Antibody titres were assessed in maternal and cord blood samples by both immunoglobulin (Ig)G-binding enzyme-linked immunosorbent assay (ELISA) and haemagglutination inhibition assay (HAI). Antibody titres to the H1N1 component were significantly higher in infants born to mothers vaccinated in either the second or third trimesters than infants born to unvaccinated mothers. HAI levels in the infant were significantly lower when maternal immunization was performed less than 4 weeks before birth. These studies confirm that immunization during pregnancy increases the antibody titre in infants. Importantly, antibody levels in cord blood were significantly higher when the mother was vaccinated in either trimesters 2 or 3, although titres were significantly lower if the mother was immunized less than 4 weeks before birth. Based on these data, seasonal influenza vaccination should continue to be given in pregnancy as soon as it becomes available.

Abstract
BACKGROUND Enhanced recovery pathways (ERPs) aim to reduce length of stay without adversely affecting short-term outcomes. High pharmaceutical costs associated with ERP regimens, however, remain a significant barrier to widespread implementation. We hypothesized that ERP would reduce hospital costs after elective colorectal resections, despite the use of more expensive pharmaceutical agents. STUDY DESIGN An ERP was implemented in January 2016 at our institution. We collected data on consecutive colorectal resections for 1 year before adoption of ERP (traditional, n = 160) and compared them with consecutive resections after universal adoption of ERP (n = 146). Short-term surgical outcomes, total direct costs, and direct hospital pharmacy costs were compared between patients who received the ERP and those who did not. RESULTS After implementation of the ERP, median length of stay decreased from 5.0 to 3.0 days (p < 0.01). There were no differences in 30-day complications (8.1% vs 8.9%) or hospital readmission (11.9% vs 11.0%). The ERP patients required significantly less narcotics during their index hospitalization (211.7 vs 720.2 morphine equivalence units; p < 0.01) and tolerated a regular diet 1 day sooner (p < 0.01). Despite a higher daily pharmacy cost ($477 per day vs $318 per day in the traditional cohort), the total direct pharmacy cost for the hospitalization was reduced in ERP patients ($1,534 vs $1,859; p = 0.016). Total direct cost was also lower in ERP patients ($9,791 vs $11,508; p = 0.004). CONCLUSIONS Implementation of an ERP for patients undergoing elective colorectal resection substantially reduced length of stay, total hospital cost, and direct pharmacy cost without increasing complications or readmission rates. Enhanced recovery pathway after colorectal resection has both clinical and financial benefits. Widespread implementation has the potential for a dramatic impact on healthcare costs.

Abstract
No reported cases to date describe herpes simplex virus (HSV) myelitis in association with cancer and chemo-radiation. We report a case of sub-acute HSV myelitis in a 54-year-old man receiving chemo-radiation with 5-flourouracil for esophageal cancer who presented to the emergency department with increasing numbness in both lower limbs that gradually spread to waist level. Magnetic resonance imaging with gadobutrol contrast 1 week later showed transverse myelitis involving the dorsal columns. Radiation-induced myelitis was suspected, and the patient was initially treated with dexamethasone; however, CSF analysis revealed HSV myelitis. Treatment with antivirals resolved much of the numbness. HSV myelitis can be confused with complications of radiation or malignancy in patients presenting with focal neurological deficits.

Abstract
BACKGROUND Hepatitis C virus (HCV) testing and counselling have the potential to impact individual behaviour and transmission dynamics at the population level. Evidence of the impact of an HCV-positive status notification on injection risk reduction is limited. The objective of our study was to (1) assess drug and alcohol use and injection risk behaviours following notification; (2) to compare behaviour change in people who inject drugs (PWID) who received a positive test result and those who remained negative; and (3) to assess the effect of age on risk behaviour. METHODS Data from the International Collaboration of Incident HIV and HCV Infection in Injecting Cohorts (InC3 Study) were analysed. Participants who were initially HCV seronegative were followed prospectively with periodic HCV blood testing and post-test disclosure and interview-administered questionnaires assessing drug use and injection behaviours. Multivariable generalised estimating equations were used to assess behavioural changes over time. RESULTS Notification of an HCV-positive test was independently associated with a small increase in alcohol use relative to notification of a negative test. No significant differences in postnotification injection drug use, receptive sharing of ancillary injecting equipment and syringe borrowing postnotification were observed between diagnosis groups. Younger PWID receiving a positive HCV test notification demonstrated a significant increase in subsequent alcohol use compared with younger HCV negative. CONCLUSIONS The proportion of PWID reporting alcohol use increased among those receiving an HCV-positive notification, increased the frequency of alcohol use postnotification, while no reduction in injection drug use behaviours was observed between notification groups. These findings underscore the need to develop novel communication strategies during post-test notification to improve their impact on subsequent alcohol use and risk behaviours.

Abstract
There is concern that intentional weight loss may generate excessive loss of fat-free mass (FFM). Idealists target minimal loss of FFM, while others consider that FFM loss of up to 25% of weight loss is acceptable. In a cross-sectional study of 275 weight-stable, overweight or obese adults, we used whole-body dual-energy X-ray absorptiometry to measure FFM. A range of models was used to estimate the expected ΔFFM/Δweight ratio required to attain the body composition of a weight-stable individual at a lower body mass index (BMI). Higher BMI was associated linearly with higher FFM in men and women. Proportional ΔFFM/Δweight was influenced by sex, BMI and age. Direct scatter plot analysis, quadratic curve fit modelling and linear FFM-BMI modelling provided similar estimates for each model of ΔFFM/Δweight ratio, with 40% for men and 33% for women. These results show that the 25% rule is inappropriate and our estimates are higher than those generally reported after intentional weight loss indicating favourable preservation of FFM.

Abstract
In the present investigation, we have attempted to identify regions of the genome in which "obesity genes" potentially reside using robust sib-pair linkage analysis. Data were collected on 1,628 individuals in 301 nuclear families residing in the environs of Québec City during the period 1978-1981. In addition to traditional blood group antigens and enzyme polymorphisms, several phenotypes in the obesity domain that are associated with increased morbidity were assessed, including measures relating to heaviness (i.e., the body mass index), body composition and nutrient partitioning (i.e., % body fat), and regional fat distribution without and with standardization for total fat mass (i.e., the sum of six skinfold thicknesses, and the ratio of the sums of trunk to extremity skinfold thicknesses). Three consistent patterns of potential linkage relationships with obesity phenotypes were revealed in these data, involving the marker loci adenosine deaminase, the Kell blood group antigen, and esterase D, which identify chromosomal regions 20q13, 7q33, and 13q14, respectively. Other potential linkages also were identified in the short arm of chromosome 1, interesting because of the presence of the db and fa loci on homologous regions of chromosome 1 in mouse and rat models of obesity, respectively. Each of the tentative linkage relationships reported here warrant follow-up using alternative methods and require replication in independent studies.

Abstract
Interest in a single gene etiology for obesity, as assessed by the body mass index (BMI), has been spurred recently by reports of a putative recessive major gene for extreme values, which accounts for as much as 40% of the variance. The major gene hypothesis was evaluated here in the Québec Family Study, a random sample of 375 French-Canadian volunteer families. This report represents one component in a more complete investigation of obesity in these families. In contrast to the recent studies, a major gene hypothesis for BMI was not verified here. Although there was a major effect, it did not conform to a Mendelian pattern of transmission. A multifactorial component (i.e., polygenic and/or common environmental factors) accounted for 42% of the phenotypic variance. In addition, evidence of heterogeneity between the generations was found. The heterogeneity was traced to the major non-Mendelian component (which accounted for 0.01% of the variance in parents and over 40% in offspring) rather than to the multifactorial one. These results would suggest that a simple recessive gene mixed model may not be sufficient to explain the familial distribution of the BMI. Several factors which may have contributed to these results include temporal trends and surrogate effects such as those related to variation in body composition and energy balance components.

Abstract
We use a multitype continuous time Markov branching process model to describe the dynamics of the spread of parasites of two types that can mutate into each other in a common host population. While most mathematical models for the virulence of infectious diseases focus on the interplay between the dynamics of host populations and the optimal characteristics for the success of the pathogen, our model focuses on how pathogen characteristics may change at the start of an epidemic, before the density of susceptible hosts decline. We envisage animal husbandry situations where hosts are at very high density and epidemics are curtailed before host densities are much reduced. The use of three pathogen characteristics: lethality, transmissibility and mutability allows us to investigate the interplay of these in relation to host density. We provide some numerical illustrations and discuss the effects of the size of the enclosure containing the host population on the encounter rate in our model that plays the key role in determining what pathogen type will eventually prevail. We also present a multistage extension of the model to situations where there are several populations and parasites can be transmitted from one of them to another. We conclude that animal husbandry situations with high stock densities will lead to very rapid increases in virulence, where virulent strains are either more transmissible or favoured by mutation. Further the process is affected by the nature of the farm enclosures.

Abstract
AIMS/HYPOTHESIS Exercise training improves glucose homeostasis, but large inter-individual differences are reported, suggesting a role of genetic factors. We investigated whether variants either confirmed or newly identified as diabetes susceptibility variants through genome-wide association studies (GWAS) modulate changes in phenotypes derived from an IVGTT in response to an endurance training programme. METHODS We analysed eight polymorphisms in seven type 2 diabetes genes (CDKAL1 rs7756992; CDKN2A and CDKN2B rs10811661 and rs564398; HHEX rs7923837; IGF2BP2 rs4402960; KCNJ11 rs5215; PPARG rs1801282; and TCF7L2 rs7903146) in a maximum of 481 sedentary, non-diabetic white individuals, who participated in a 20-week endurance training programme. Associations were tested between the variants and changes in IVGTT-derived phenotypes. RESULTS The only evidence of association with training response was found with PPARG rs1801282 (Pro12Ala). We observed that Ala carriers experienced greater increase in overall glucose tolerance (Deltaglucose disappearance index Ala/Ala 0.22 +/- 0.22, Pro/Ala 0.14 +/- 0.06, Pro/Pro 0.004 +/- 0.03; p = 0.0008), glucose effectiveness (Ala/Ala 0.28 +/- 0.41, Pro/Ala 0.44 +/- 0.14, Pro/Pro 0.09 +/- 0.06; p = 0.004), acute insulin response to glucose (Ala/Ala 64.21 +/- 37.73, Pro/Ala -11.92 +/- 40.30, Pro/Pro -46.30 +/- 14.70; p = 0.03) and disposition index (Ala/Ala 551.8 +/- 448.5, Pro/Ala 534.6 +/- 218.3, Pro/Pro -7.44 +/- 88.18; p = 0.003). CONCLUSIONS/INTERPRETATION Compared with Pro/Pro individuals, PPARG Ala carriers experienced greater improvements in glucose and insulin metabolism in response to regular endurance training. However, we did not find evidence of association between type 2 diabetes susceptibility variants recently identified through GWAS and glucose homeostasis response to exercise. Our results extend those of previous studies showing that Ala carriers appear to be more responsive to beneficial health effects of lifestyle interventions.

Abstract
BACKGROUND Blood pressure (BP) responses to dietary sodium and potassium intake vary among individuals. We examined the correlation between BP responses to dietary low-sodium, high-sodium, and potassium supplementation interventions in a feeding study. METHODS A total of 1,906 Chinese aged > or = 16 years participated in the dietary intervention that included a 7-day low-salt intervention (51.3 mmol/day), a 7-day high-salt intervention (307.8 mmol/day), and a 7-day high-salt plus potassium supplementation (60 mmol/day) intervention. BP was measured nine times during the 3-day baseline observation and during the last 3 days of each intervention phase using a random-zero sphygmomanometer. RESULTS The correlation coefficients (95% confidence intervals (CIs)) of the BP responses to low-sodium and high-sodium interventions were -0.47 (-0.51 to -0.44), -0.47 (-0.50 to -0.43), and -0.45 (-0.49 to -0.42) for systolic BP (SBP), diastolic BP (DBP), and mean arterial pressure (MAP), respectively (all P < 0.0001). The correlation coefficients (95% CI) of the BP responses to high-sodium intervention and potassium supplementation were -0.52 (-0.56 to -0.49), -0.48 (-0.52 to 0.45), and -0.52 (-0.55 to -0.48) for SBP, DBP, and MAP, respectively (all P < 0.0001). The kappa coefficients were moderate, varying from 0.28 to 0.34, between BP responses to low-sodium and high-sodium interventions (all P < 0.0001). CONCLUSIONS These results indicate there is a moderate correlation between BP responses to low-sodium and to high-sodium interventions, and BP responses to high-sodium intervention and potassium supplementation. Furthermore, our study suggests that individuals who were more sensitive to high-sodium diet might benefit more from a low-sodium and/or high-potassium intervention aimed at lowering BP levels.

Abstract
7551 Purpose: To describe the effects of multimodality treatment on lung function in patients with stage III non-small cell carcinoma of the lung (NSCLC) Methods: Pulmonary function tests (PFTs) were reviewed for 32 patients with stage III NSCLC who were enrolled in a multimodality protocol that included neoadjuvant (NAd) combined chemoradiotherapy (taxol 50 mg/m2, carboplatin AUC 2 weekly X 3, radiation (XRT) 1.8 Gy BID to 30 Gy + erlotinib 150 mg/d for 28 days, followed by resection (R) and adjuvant (Ad) chemoradiotherapy (same as induction) followed by erlotinib 150mg/d maintenance (M) for 2 years. Changes in PFTs were analyzed at multiple time points (baseline to after NAd, after NAd to after R, after R to after Ad) and for the overall effect of treatment (baseline to the end of treatment). Results: The table below shows changes in percent predicted pulmonary function test values at each step in the treatment course. + signifies an increase and - a decrease. P indicates pneumonectomy and L lobectomy. Numbers in parentheses are the number of patients with complete testing at that time point. Conclusions: Neoadjuvant combined chemoradiotherapy has a small effect on lung function testing. The combined effect of multimodality therapy for stage III lung cancer that includes surgical resection leads to larger declines in lung function than have been reported historically for resection alone.

Abstract
AIMS/HYPOTHESIS The expression of the four and a half LIM domains 1 gene (FHL1) is increased in the muscle of individuals who show an improvement in insulin sensitivity index (S(I)) after 20 weeks of exercise training. The aim of the present study was to investigate associations between three FHL1 single nucleotide polymorphisms (SNPs) and variables derived from an IVGTT, both in the sedentary state and in response to exercise training, in participants in the HERITAGE Family Study. MATERIALS AND METHODS SNPs were typed using fluorescence polarisation methodology. Analyses were performed separately by sex and in black and white individuals. RESULTS In black participants, no associations were found with any of the SNPs. In white women (n = 207), SNP rs9018 was associated with the disposition index (D(I)), which is calculated as S(I) generated from the MINMOD program (x10(-4) min(-1)[microU/ml](-1)) multiplied by acute insulin response to glucose (AIR(g); pmol/l x 10 min), and the glucose disappearance index (K(g)) training responses (p = 0.016 and p = 0.008, respectively). In white men (n = 222), all SNPs were associated with fasting glucose levels (p < or = 0.05) and SNP rs2180062 with the insulin sensitivity index (S(I)) (p = 0.04) in the sedentary state. Two SNPs were associated with fasting insulin training response. Fasting insulin decreased to a greater extent in carriers of the rs2180062 C allele (p = 0.01) and rs9018 T allele (p = 0.04). With exercise training, S(I) (x10(-4) min(-1)[microU/ml](-1): 0.68 +/- 0.20 vs -0.77 +/- 0.44, p = 0.046), D(I) (319 +/- 123 vs -528 +/- 260, p = 0.006) and K(g) (per 100 min: 0.09 +/- 0.04 vs -0.14 +/- 0.8, p = 0.03) improved more in the C allele carriers at rs2180062 than in the T allele carriers. CONCLUSIONS/INTERPRETATION Fasting insulin and S(I) responses to exercise training were associated with DNA sequence variation in FHL1 in white men. Whether these associations exist only in white men remains to be investigated.

Abstract
Evidence of a genetic component for resting heart rate (RHR) has been found. Quantitative trait loci (QTLs) for baseline RHR have been reported, but not for RHR training response. It is of interest to identify QTLs that may harbor genes influencing RHR variation at baseline and in response to regular exercise training. Here, a multipoint variance components linkage scan using 654 markers was performed to search for QTLs that influence RHR adjusted for several covariates at baseline and in response to 20 weeks of endurance training (post-training minus baseline) in 99 White and 127 Black families in the HERITAGE Family Study. Potentially interesting linkages were revealed on 4 q and 11 p for baseline RHR, and on 1 q and 21 q for RHR training response in Whites. The QTLs on 2 q, 6 q, 7 q, 12 q, 14 q, and 15 q for baseline RHR, and on 3 p, 20 p and 21 q for RHR training response were found in Blacks. Promising linkages (lod scores >or= 1.75, p <or= 0.0023) involved 11 p for baseline RHR in Whites and 3 p for RHR training response in Blacks, which did not replicate across races. Interestingly in this study, the linkage evidence on 11 p at the SUR locus was somewhat enhanced (lod score went up from 1.7 to 2.0) in a prehypertensive (BP >or= 135/80 mm Hg) subset of 40 White families suggesting a pleiotropic gene for BP and RHR with interactions. In conclusion, among QTLs on 1 q, 2 p, 3 p, 4 q, and 11 p that replicated across subsamples and studies, 11 p is most promising for dense mapping and association studies in HERITAGE and other cohorts.

Abstract
4062 Background: The predictive value of FDG-PET SUV in pts with esophageal and GEJ cancer has been subject of recent interest. The heterogeneity of disease stages and treatments made interpretation of reported data difficult.We evaluated the value of baseline FDG-PET SUV in a homogeneous patient (pt) population treated in a uniform fashion. Methods: Retrospective analysis of 71 pts with stages II-IVa esophageal and GEJ cancer treated on 2 phase 2 trials at the Cleveland Clinic Foundation. Data was collected on baseline pt and tumor characteristics, baseline SUV uptake, and outcomes. Results: All pts were treated with preoperative concurrent fluorouracil/cisplatin chemoradiotherapy (CRT); 69 pts proceeded to esophagectomy and 58 pts received additional postoperative adjuvant CRT. Median pt age was 60 (range 33–75) years, 86% were male, 89% had adenocarcinoma, 35%, 41% and 24% had stage II, III and IVa disease respectively. Pts have been followed for a median of 14 (range 3–50) months. All pts underwent a baseline FDG-PET scan with a mean primary site SUV of 8.9 (range 0–28.2). Pathological response (complete or partial) was achieved after induction CRT in 54% and was more likely in those with a baseline primary site SUV ≥ 7.3 (OR: 3.95, 1.43–10.9, P=0.008). Recurrence developed in 33 pts (46.5%) with distant metastases identified in 31 of these 33. The Kaplan-Meier 2-year projected overall survival for all 71 pts is 58% with a median of 31 months. Mortality was less in pts with baseline SUV ≥ 5.0 (HR: 0.44, 0.20–0.94, P = 0.033). After adjusting for clinical stage at diagnosis, tumor location and histology, baseline SUV ≥ 5 was still predictive of improved survival in multivariate analysis (HR: 0.35, 0.15–0.85, P = 0.02). Conclusions: In this retrospective analysis, esophageal and GEJ cancer pts with a higher baseline primary site SUV were more likely to respond to induction CRT and had better overall survival. This observation suggests that the subset of pts with more metabolically active tumor may derive greater benefit from multimodality treatments that include CRT. A prospectively designed trial would be required to confirm this hypothesis. No significant financial relationships to disclose.

Abstract
AIMS/HYPOTHESIS Impaired insulin secretion, insulin action, insulin-independent glucose effectiveness, glucose tolerance and the associated abnormalities in insulin and glucose metabolism phenotypes are precursors of type 2 diabetes. Genome-wide multipoint variance component linkage scans were carried out using 654 markers to identify quantitative trait loci for insulin sensitivity, acute insulin response to glucose, disposition index and glucose effectiveness training responses in whites and blacks in the HERITAGE Family Study. METHODS These phenotypes were obtained from an IVGTT with the minimal model. The distributions of insulin sensitivity, acute insulin response to glucose and disposition index training responses (post-training minus baseline) were approximately normalised using a square-root transformation. All phenotypes were adjusted for the effects of age, BMI and their respective baseline values within sex and generation by race prior to linkage scans. RESULTS In blacks, a promising linkage with a maximum lod score of 3.1 on 19q (54-62 Mb) for glucose effectiveness training response was found. Six interesting linkages with lod scores of at least 1.0 were found for disposition index training response in whites. They included 1p (30 Mb), 3q (152 Mb), 6p (23-42 Mb), 7q (95-96 Mb), 10p (15 Mb) and 12q (119-126 Mb). CONCLUSIONS/INTERPRETATION Quantitative trait loci for 20 weeks of endurance exercise training responses in insulin action and glucose metabolism phenotypes were found on chromosome 19q as well as 6p and 7q, with nominal (6p, 7q) but consistent (6p) linkages across the races.
