Abstract
Physical function (PF) limitations are common in aging. However, there is a dearth of interventions focused on addressing PF limitations in community-based settings, particularly in minoritized communities. To guide intervention development, we conducted focus groups to understand perceptions of PF limitations, gauge intervention interest, and identify potential intervention strategies as part of a large health partnership of African American churches in Chicago, IL. Participants were age 40+ years with self-reported PF limitations. Focus groups (N=6 focus groups; N=40 participants) were audio recorded, transcribed, and analyzed using thematic analysis methods.Six themes were identified: (1) causes of PF limitations, (2) impact of PF limitations, (3) terminology and communication, (4) adaptations and treatments, (5) faith and resilience, and (6) prior program experiences. Participants described how PF limitations affected their ability to live a full life and play an active role in their family, church, and community. Faith and prayer aided in coping with limitations and pain. Participants expressed that it is important to keep moving, both from an emotional (not giving up) and physical (to prevent further exacerbation of limitations) standpoint. Some participants shared adaptation and modification strategies, but there were overall frustrations with communicating regarding PF limitations and obtaining medical care for them. Participants expressed that they would like to have programs in their church focused on improving PF (including physical activity), particularly as their communities often lacked resources conducive to being active. Community-based programs focusing on reducing PF limitations are needed, and the church is a potentially receptive setting.

Abstract
Background Engaging diverse populations in clinical trials is vital to research. This study evaluated the effects of varying recruitment messages for a clinical trial. Methods The messages were evaluated in a randomly assigned, factorial design that tested enhanced trust (vs. standard) and participant endorsement (vs. standard) messaging.Four postcards were developed and randomly assigned to 4000 potential participants' addresses. Except for the messages of interest, the cards were identical, and participants were directed to four identical study websites and screening forms. Outcomes include unique website visits, visit conversion rate, screening forms completed, and participants randomized into the parent study. Results Study websites received 74 visits (range by message type 9 to 34). There was no significant difference by message type (p = 0.79). Online screening forms were completed by 15 participants (range by message type 0-6), representing a conversion rate of 20.3% of website visits. Seven participants were randomized into the study in response to the postcards (range by message type 0 to 3; 46.7% of screenings). Overall, 0.2% of individuals who received a postcard were randomized into the study. Conclusion Despite developing recruitment messages with participant input, the enhanced messages did not yield a greater response than standard messages. However, this method of evaluating recruitment messages shows promise.

Abstract
BACKGROUND Young men are vastly underrepresented in lifestyle interventions, suggesting a need to develop appealing yet effective interventions for this population. OBJECTIVE This study aimed to determine the acceptability of a self-guided lifestyle intervention designed specifically for young men (age: 18-35 years old). METHODS Semistructured interviews and surveys were completed by 14 men following completion of a remotely delivered, 12-week lifestyle intervention. The intervention included 1 virtual group session, digital tools, access to self-paced web- and mobile-based content, and 12 weekly health risk text messages. We quantitatively and qualitatively examined young men's experiences with the intervention components of a remotely delivered, self-guided lifestyle intervention targeting weight loss. Data were integrated using convergent mixed methods analysis. RESULTS Men were a mean age of 29.9 (SD 4.9) years with a mean BMI of 31.0 (SD 4.5) kg/m2. The self-guided aspect was not acceptable, and a majority preferred more check-ins. Participants expressed a desire for a social aspect in future lifestyle interventions. All men found the focus on health risks appealing. A majority of men found the study-issued, Bluetooth-enabled scale acceptable. CONCLUSIONS Acceptability of the self-guided lifestyle intervention was perceived as suboptimal by young men. The findings highlight the need to add intervention components that sustain motivation and provide additional social support for young men.

Abstract
Objective Men who work in skilled and unskilled trades and labor occupations (i.e., blue-collar occupations), have high rates of obesity and associated comorbidities but are underrepresented in weight loss programs. A first step in engaging this group is to better understand their preferences for weight loss programs. Methods Respondents were men working in trade and labor occupations, with overweight/obesity, and an interest in losing weight. A discrete choice experiment was developed, and the data were analyzed using mixed logit model. Respondent characteristics were tested as effect modifiers. Results Respondents (N = 221, age (M ± SD) 45.0 ± 12.6, BMI 33.3 ± 6.3, 77% non-Hispanic white) working in a variety of occupations (construction 31%, manufacturing 30%, transportation 25%, maintenance/repair 14%) participated in this study. Results indicate preferences for programs that encourage making smaller dietary changes, are delivered online, and do not incorporate competition. Results were consistent across sensitivity analyses and most respondent groups. Conclusions The results suggest specific ways to make weight loss programs more appealing to men in trade and labor occupations. Using experimental methods to quantify preferences using larger, more representative samples would further assist in tailoring behavioral weight loss programs for under-reached populations.

Abstract
Over 70% of men are overweight, and most desire weight loss; however, men are profoundly underrepresented in weight loss programs. Gamification represents a novel approach to engaging men and may enhance efficacy through two means: (1) game-based elements (e.g., streaks, badges, team-based competition) to motivate weight control behaviors and (2) arcade-style "neurotraining" to enhance neurocognitive capacities to resist the temptation of unhealthy foods and more automatically select healthy foods. This study will use a 2 × 2 factorial design to examine the independent and combinatory efficacy of gamification and inhibitory control training (ICT). Men with overweight/obesity (N = 228) will receive a 12-month mobile weight loss program that incorporates behavioral weight loss strategies (e.g., self-monitoring, goal setting, stimulus control). Men will be randomly assigned to a non-gamified or gamified version, and an active or sham ICT. A game design company will create the program, with input from a male advisory panel. Aims of the project are to test whether a gamified (versus non-gamified) weight loss program and/or ICT (versus sham) promotes greater improvements in weight, diet, and physical activity; whether these treatment factors have combinatory or synergistic effects; to test whether postulated mechanisms of action (increased engagement, for gamification, and inhibitory control, for ICT) mediate treatment effects; and whether baseline gameplay frequency and implicit preferences for ICT-targeted foods moderate effects. It is hoped this study will contribute to improved mHealth programs for men and enhance our understanding of the impact of gamified elements and neurocognitive training on weight control.

Abstract
Introduction Obtaining body weights remotely could improve feasibility of pragmatic trials. This investigation examined whether weights collected via cellular scale or electronic health record (EHR) correspond to gold standard in-person study weights. Methods The agreement of paired weight measurements from cellular scales were compared to study scales from a weight loss intervention and EHR-collected weights were compared to study scales from a weight loss maintenance intervention. Differential weight change estimates between intervention and control groups using both pragmatic methods were compared to study collected weight. In the Log2Lose feasibility weight loss trial, in-person weights were collected bi-weekly and compared to weights collected via cellular scales throughout the study period. In the MAINTAIN weight loss maintenance trial, in-person weights were collected at baseline, 14, 26, 42 and 56 weeks. All available weights from the EHR during the study period were obtained. Results On average, in Log2Lose cellular scale weights were 0.6 kg (95% CI: -2.9, 2.2) lower than in-person weights; in MAINTAIN, EHR weights were 2.8 kg (SE: -0.5, 6.0) higher than in-person weights. Estimated weight change using pragmatic methods and study scales in both studies were in the same direction and of similar magnitude. Conclusion Both methods can be used as cost-effective and real-world surrogates within a tolerable variability for the gold-standard. Trial registration NCT02691260; NCT01357551.

Abstract
Men who work in blue-collar occupations (skilled and unskilled trades) experience high rates of obesity and comorbid conditions. This group is underrepresented in behavioral interventions for weight management, which may stem from a mismatch between the features of available programs and these men's preferences. This qualitative study explored the views of these men, their experiences with weight loss, their preferences for weight loss programs, and messaging related to these programs. We conducted remote interviews with 20 men (age: 43 ± 13 years, M ± SD) currently working in blue-collar occupations (50% construction, 25% transportation, and 25% manufacturing) who had body mass indices (BMIs) in the overweight/obese categories (BMI: 33 ± 6 kg/m2). Deductive codes and summary themes were developed and discussed by the first two authors. A selection of transcripts was reviewed following theme development to confirm accuracy of the themes. Most participants (n = 16, 80%) reported a prior weight loss attempt. The most common approaches to weight loss reported were increased exercise and following their own approach to changing diet (e.g., "eating less junk food"). For program and message preferences, two major themes emerged: participants wanted accurate and trustworthy information and wanted programs that fit their lifestyle. Results suggest that weight loss programs targeting men working in blue-collar occupations should emphasize the accuracy of information related to the program and the ease of incorporating it into participants' lifestyles. There is an urgent need to incorporate these preferences into effective programs.

Abstract
Background Young men are at high risk for developing obesity-related health complications, yet are markedly underrepresented in lifestyle interventions. This pilot study examined the feasibility and preliminary efficacy of a lifestyle intervention (self-guided + health risk messaging) targeting young men. Methods 35 young men (Age = 29.3 ± 4.27; BMI = 30.8 ± 4.26; 34% racial/ethnic minority) were randomly assigned to the intervention or delayed treatment control. The intervention (ACTIVATE) included 1 virtual group session, digital tools (wireless scale, self-monitoring app), access to self-paced content via a secure website, and 12 weekly texts to reinforce health risk messaging. Fasted objective weight was assessed remotely at baseline and 12-weeks. Perceived risk was assessed via survey at baseline, 2-week, and 12-week. T-tests were used to compare weight outcomes between arms. Linear regressions examined the association between percent weight change and perceived risk change. Results Recruitment was successful as evidenced by 109% of target enrollment achieved in a 2-month period. Retention was 86% at 12 weeks, with no differences by arm (p = 0.17). Participants in the intervention arm experienced modest weight loss at 12 weeks, whereas slight gains were observed in the control arm (-1.6% ± 2.5 vs. +0.31% ± 2.8, p = 0.04). Change in perceived risk was not associated with change in percent weight (p > 0.05). Conclusions A self-guided lifestyle intervention showed initial promise for weight management among young men, but these findings are limited by small sample size. More research is needed to bolster weight loss outcomes while retaining the scalable self-guided approach.

Abstract
OBJECTIVES Individuals working in blue-collar occupations experience high rates of cardiovascular disease (CVD). The purpose of this systematic review is to describe the characteristics and efficacy of behavioural interventions that have targeted CVD risk factors in this high-risk group. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched seven databases to find interventions focused on changing the following: blood pressure, cholesterol, diet, physical activity, smoking or weight. Eligible studies tested a behavioural intervention (not exclusively policy, environmental, or pharmaceutical), in individuals working in blue-collar occupations using a randomised study design. Study quality was evaluated using the National Heart, Lung, and Blood Institute's study quality assessment tool. RESULTS 22 studies evaluating 31 interventions were included: 11 were rated as 'good' or 'fair' quality. Intervention intensity ranged from a single contact via a mailed letter to studies that included individual-level contacts at multiple time points between staff and participants. Studies that included at least some individual contact generally yielded the greatest effects. Interventions had the greatest observed effects on self-report changes in diet, regardless of intervention intensity. Four of the five higher quality studies that explicitly tailored the intervention to the occupational group were successful at reducing at least one risk factor. CONCLUSIONS Interventions that used individual contact and tailored the intervention to the occupational setting yielded the greatest effects on CVD risk-factor reduction in individuals working in blue-collar occupations. Generally, studies were low quality but showed promising effects for reaching this high-risk population. Future work should incorporate these promising findings in higher quality studies.

Abstract
BACKGROUND State-of-the-art behavioral weight loss treatment (SBT) can lead to clinically meaningful weight loss, but only 30-60% achieve this goal. Developing adaptive interventions that change based on individual progress could increase the number of people who benefit. PURPOSE Conduct a Sequential Multiple Assignment Randomized Trial (SMART) to determine the optimal time to identify SBT suboptimal responders and whether it is better to switch to portion-controlled meals (PCM) or acceptance-based treatment (ABT). METHOD The BestFIT trial enrolled 468 adults with obesity who started SBT and were randomized to treatment response assessment at Session 3 (Early TRA) or 7 (Late TRA). Suboptimal responders were re-randomized to PCM or ABT. Responders continued SBT. Primary outcomes were weight change at 6 and 18 months. RESULTS PCM participants lost more weight at 6 months (-18.4 lbs, 95% CI -20.5, -16.2) than ABT participants (-15.7 lbs, 95% CI: -18.0, -13.4), but this difference was not statistically significant (-2.7 lbs, 95% CI: -5.8, 0.5, p = .09). PCM and ABT participant 18 month weight loss did not differ. Early and Late TRA participants had similar weight losses (p = .96), however, Early TRA PCM participants lost more weight than Late TRA PCM participants (p = .03). CONCLUSIONS Results suggest adaptive intervention sequences that warrant further research (e.g., identify suboptimal responders at Session 3, use PCMs as second-stage treatment). Utilizing the SMART methodology to develop an adaptive weight loss intervention that would outperform gold standard SBT in a randomized controlled trial is an important next step, but may require additional optimization work.

Abstract
BACKGROUND Individuals receiving behavioral weight loss treatment frequently fail to adhere to prescribed dietary and self-monitoring instructions, resulting in weight loss clinicians often needing to assess and intervene in these important weight control behaviors. A significant obstacle to improving adherence is that clinicians and clients sometimes disagree on the degree to which clients are actually adherent. However, prior research has not examined how clinicians and clients differ in their perceptions of client adherence to weight control behaviors, nor the implications for treatment outcomes. PURPOSE In the context of a 6-month weight-loss treatment, we examined differences between participants and clinicians when rating adherence to weight control behaviors (dietary self-monitoring; limiting calorie intake) and evaluated the hypothesis that rating one's own adherence more highly than one's clinician would predict less weight loss during treatment. METHODS Using clinician and participant-reported measures of self-monitoring and calorie intake adherence, each assessed using a single item with a 7- or 8-point scale, we characterized discrepancies between participant and clinician adherence and examined associations with percent weight change over 6 months using linear mixed-effects models. RESULTS Results indicated that ratings of adherence were higher when reported by participants and supported the hypothesis that participants who provided higher adherence ratings relative to their clinicians lost less weight during treatment (p < 0.001). CONCLUSIONS These findings suggest that participants in weight loss treatment frequently appraise their own adherence more highly than their clinicians and that participants who do so to a greater degree tend to lose less weight.

Abstract
Traumatic stress and posttraumatic stress disorder (PTSD) are overrepresented in urban African American communities, and associated with health risk behaviors such as tobacco use. Support and resources provided by churches may reduce trauma-related health risks. In the current study, we assessed weekly church attendance as a moderator of relations between (a) traumatic event exposure and probable PTSD, and (b) probable PTSD and tobacco use. Data were drawn from a health surveillance study conducted in seven churches located in Chicago's West Side. Participants (N = 1015) were adults from churches as well as the surrounding community. Trauma exposure was reported by 62% of participants, with 25% of those who experienced trauma reporting probable PTSD. Overall, more than one-third of participants (37.2%) reported current tobacco use. As compared with non-weekly church attendance, weekly church attendance was associated with a lower likelihood of PTSD (odds ratio [OR] = 0.41; 95% confidence interval [CI] = 0.26-0.62; p < .0001) and lower tobacco use overall (OR = 0.22; 95% CI = 0.16-0.30; p < .0001), but did not moderate the effect of trauma exposure on risk of PTSD, or the effect of PTSD on tobacco use. Findings support church attendance as a potential buffer of trauma-related stress.

Abstract
BACKGROUND Physical activity and sleep are two time-dependent behaviors with important health implications. The amount of time people have to engage in these behaviors may vary based on their everyday work, social circumstances (e.g., parenthood), and social location (e.g., gender). AIMS The current study aimed to explore the ways work, social circumstances, and social locations combine that lead to heterogeneity in the time-dependent health behaviors of physical activity and time spent in bed (i.e., sleep) among a young adult population. We drew upon two conceptual frameworks-Constrained Choices and an intersectionality perspective-and examined multiple work characteristics (e.g., number of jobs), social circumstances (e.g., household income), and social locations (e.g., U.S. nativity) relevant to young adulthood. METHODS 2015-2016 data from a Minneapolis-St. Paul, U.S. cohort of 1830 young adults (25-36 years) were analyzed using conditional inference tree (CIT)-a data-driven approach which identifies population sub-groups that differ in their outcome values as well as in the interacting factors that predict outcome differences. Sensitivity analyses to evaluate CIT robustness were also performed. RESULTS CITs revealed four relevant sub-groups for physical activity (sub-group averages ranged = 2.9-4.9 h per week), with working mothers achieving the least activity, and six relevant sub-groups for time in bed (range = 7.8-8.7 h per day), with full-time working men obtaining the least. In both models, parent status and employment status/hours were found to consistently differentiate behavior among women but not men. CONCLUSION According to these data, time to engage in physical activity and time in bed was constrained by particular everyday contexts (work and parent status) and the extent to which these contexts mattered also depended on gender. If replicated in other studies, results suggest equitable strategies are necessary to assist all parents and workers in engaging in these time-dependent health behaviors for long-term health.

Abstract
Background The majority of participants in weight loss trials are non-Hispanic White women, while men and women of color are underrepresented. This study presents data obtained from non-targeted and targeted recruitment approaches in a trial of behavioral weight loss programs to (1) describe the yields from each approach and (2) compare the demographics, weight control histories, and study involvement of samples recruited by each approach. Methods Data for this observational study include source of recruitment, demographic information, weight loss experiences (e.g., lifetime weight loss, current weight loss behaviors), and completion of the 6-month assessment visit. Results Men comprised 14.2% of participants who responded to non-targeted recruitment efforts, while targeted efforts yielded 50.4% men. Similarly, people of color comprised 12.8% of those who responded to non-targeted approaches, whereas targeted recruitment methods yielded 47.2% people of color. Men recruited through targeted methods were younger (p = 0.01) than men recruited through non-targeted means but were otherwise similar. Women of color recruited through targeted methods reported use of fewer weight loss strategies relative to women of color recruited through non-targeted means (p = 0.006) but were otherwise similar. There were no differences by recruitment method on retention to the study. Conclusions Using targeted recruitment methods increased the ethnic and gender diversity of the recruited sample without reducing study retention. This targeting also increased the enrollment of women with less weight loss experience who may not have otherwise sought out a weight loss program. Developing and implementing a targeted recruitment plan should be considered early in the clinical trial development process. Trial registration Clinicaltrials.gov, NCT02368002.

Abstract
BACKGROUND Memory loss in older age affects women more than men and cardiovascular disease is a leading risk factor. Physical activity can improve memory in healthy older adults; however, few physical activity interventions have targeted women with cardiovascular disease, and none utilized lifestyle approaches. PURPOSE The purpose of this study was to examine feasibility, acceptability, and preliminary effects of a 24-week lifestyle physical activity intervention (physical activity prescription, five group meetings, and nine motivational interviewing calls). METHODS A sequential mixed-methods approach was used. Participants were 18 sedentary women ≥65 years with cardiovascular disease and without cognitive impairment recruited in August 2017. Feasibility, acceptability, self-reported health, accelerometer-assessed physical activity, and neurocognitive memory tests were measured using a pre-post test design. Two post-intervention focus groups (n = 8) were conducted in June 2018. Concept analysis was used to identify barriers/motivators of intervention participation. RESULTS Meeting attendance was >72% and retention was 94%. Participants rated the program with high satisfaction. There were significant improvements at 24 weeks in self-rated physical health, objective daily steps, and estimated cardiorespiratory fitness (d = .30-.64). Focus group themes generated recommendations for modifying the intervention. CONCLUSION Findings support adapting the intervention further for women with cardiovascular disease and testing it in an efficacy trial.

Abstract
OBJECTIVE Delay discounting is a neurocognitive trait that has been linked to poor nutritional health and obesity, but its role in specific dietary choices is unclear. This study tested whether individual differences in delay discounting are related to the healthfulness of household food purchases and reliance on nonstore food sources such as restaurants. METHOD The food purchases of 202 primary household food shoppers were objectively documented for 14 days through a food receipt collection and analysis protocol. The nutrient content of household food purchases was derived for each participant, and the overall diet quality (Healthy Eating Index-2015) and energy density (kcal/g) of foods and beverages were calculated. The proportion of energy from nonstore food sources was also derived. Delay discounting was assessed with a choice task featuring hypothetical monetary rewards. RESULTS Data were available for 12,624 foods and beverages purchased across 2,340 shopping episodes. Approximately 13% of energy was purchased from restaurants and other nonstore food sources. Steeper discounting rates were associated with lower overall Healthy Eating Index-2015 scores and a higher energy density (kcal/g) of purchased foods. Associations were attenuated but remained statistically significant when accounting for body mass index and sociodemographic variables. Discounting rates were unrelated to reliance on nonstore food sources or the energy density of purchased beverages. CONCLUSIONS Delay discounting is related to the healthfulness of food purchases among primary household shoppers. As food purchasing is a key antecedent of dietary intake, delay discounting may be a viable target in dietary and weight management interventions.

Abstract
Background Lower household income has been consistently associated with poorer diet quality. Household food purchases may be an important intervention target to improve diet quality among low income populations. Associations between household income and the diet quality of household food purchases were examined. Methods Food purchase receipt data were collected for 14 days from 202 urban households participating in a study about food shopping. Purchase data were analyzed using NDS-R software and scored using the Healthy Eating Index 2010 (HEI 2010). HEI total and subscores, and proportion of grocery dollars spent on food categories (e.g. fruits, vegetables, sugar sweetened beverages) were examined by household income-to-poverty ratio. Results Compared to lower income households, after adjusting for education, marital status and race, higher income households had significantly higher HEI total scores (mean [sd] = 68.2 [13.3] versus 51.6 [13.9], respectively, adjusted p = 0.05), higher total vegetable scores (mean [sd] = 3.6 [1.4] versus 2.3 [1.6], respectively, adjusted p < .01), higher dairy scores (mean [sd] = 5.6 [3.0] versus 5.0 [3.3], p = .05) and lower proportion of grocery dollars spent on frozen desserts (1% [.02] versus 3% [.07], respectively, p = .02). Conclusions Lower income households purchase less healthful foods compared with higher income households. Food purchasing patterns may mediate income differences in dietary intake quality.

Abstract
OBJECTIVE To compare food purchasing behaviors and diet quality of foods purchased between men and women who were the primary food purchaser for their households. METHODS Food purchasing was measured via itemized receipts. The dietary composition of purchased foods was derived using the Nutrition Data System for Research and quality was assessed using the Healthy Eating Index-2010. RESULTS Men comprised 17.2% of the household primary food purchasers in the sample (n = 204). There were no differences by gender in the number of items purchased or the number of receipts. Men made fewer purchases at stores (74.0%) than did women (81.4%; P < .001). There were no gender differences in the quality of foods purchased overall or by source of purchase. CONCLUSIONS AND IMPLICATIONS In primary purchasers, purchasing behaviors varied by gender but not purchases did not. Food purchasing interventions should include both genders for greatest impact.

Abstract
INTRODUCTION Self-weighing is an important component of self-monitoring during weight loss. However, methods of measuring self-weighing frequency need to be validated. This analysis compared self-reported and objective weighing frequency. METHODS Data came from a 24-month randomized controlled trial. Participants received 12 months of a behavioral weight-loss program and were randomly assigned to (1) daily self-weighing, (2) weekly weighing, or (3) no weighing (excluded from analysis). Objective weighing frequency was measured by Wi-Fi enabled scales, and self-reported weighing frequency was assessed every 6 months by questionnaire. Objective weights were categorized to match the scale of the self-report measure. RESULTS At 12 months, there was 80.8% agreement between self-reported and objective weighing frequency (weighted kappa = 0.67; P < 0.001). At 24 months, agreement decreased to 48.5% (kappa = 0.27; P < 0.001). At both time points in which disagreements occurred, self-reported frequencies were generally greater than objectively assessed weighing. Both self-reported and objectively assessed weighing frequency was associated with weight loss at 12 and 24 months (P < 0.001). CONCLUSIONS Self-reported weighing frequency is modestly correlated with objective weighing frequency; however, both are associated with weight change over time. Objective assessment of weighing frequency should be used to avoid overestimating actual frequency.

Abstract
Background Few randomized studies have examined differential effects of group size in behavioral weight control, especially in hybrid programs that include Internet treatment approaches. Methods Randomized controlled trial (n = 195) comparing a 4 month hybrid internet weight loss program coupled with monthly face to face groups of 100 persons (Large Group, LG; 1 group) or to the same approach with monthly groups of 20 persons (Small Group, SG; 4 groups). Repeated-measures mixed-model analysis with age and race as covariates were used to estimate primary (weight) and secondary outcomes, and to test group differences in change over time. Results The sample was 46.3 years old ±10.4, 90.3% female, and 51.9% non-white, with BMI 37.9 ± 8.4 kg/m2. Participants in the LG were more likely to return for the 4-month assessment visit than those in the SG (p = 0.04). Participants randomized to both the LG and SG conditions experienced significant WL over time (no between group difference: −4.1 kg and −3.7 kg, respectively) and weight loss was positively associated with attendance at monthly meetings and logins to the website. Satisfaction with the program was high and similar in both groups (94.4% reported that they were “satisfied” or “very satisfied”). Conclusions Using a hybrid approach of in-person and online weight loss interventions may be an effective way to reach larger and more diverse populations. Delivering the face to face component of the intervention in groups larger than those traditionally delivered (20–25 people) could increase the cost-effectiveness of group-based behavioral weight loss interventions.

Abstract
Men are underrepresented in weight loss programs and little is currently known about the weight loss strategies men prefer. This study describes the weight loss strategies used by men during a men-only weight loss program. At baseline, 3 months, and 6 months, participants reported how frequently they used 45 weight loss strategies including strategies frequently recommended by the program (i.e., mentioned during every intervention contact; e.g., daily self-weighing), strategies occasionally recommended by the program (i.e., mentioned at least once during the program; e.g., reduce calories from beverages), and strategies not included in the program (e.g., increase daily steps). At baseline participants ( N = 107, 44.2 years, body mass index = 31.4 kg/m2, 76.6% White) reported regularly using 7.3 ± 6.6 ( M ± SD) strategies. The intervention group increased the number of strategies used to 19.1 ± 8.3 at 3 months and 17.1 ± 8.4 at 6 months with no changes in the waitlist group. The intervention group reported increased use of most of the strategies frequently recommended by the program (4 of 5), nearly half of the strategies occasionally recommended by the program (10 of 24), and one strategy not included in the program (of 16) at 6 months. The intervention effect at 6 months was significantly mediated by the number of strategies used at 3 months. This study adds to what is known about men's use of weight loss strategies prior to and during a formal weight loss program and will help future program developers create programs that are tailored to men.

Abstract
The purpose of this study is to explore gender differences in reasons for losing weight, weight loss methods, and weight loss behaviors prior to and during a weight loss maintenance trial. This is a secondary analysis of data from a 24-month randomized controlled trial comparing Self-Directed or Guided phone-based weight loss maintenance interventions among adults who had intentionally lost ≥10% of their body weight in the year prior to enrollment. Participants reported their weight loss methods and reasons for recently losing weight at baseline. Dietary intake, physical activity, and dietary patterns were assessed at baseline, 12, and 24 months. Participants included 419 adults (18.4% men, age 47.0 ± 10.8, BMI 28.4 ± 5.0). Women were more likely than men to report having used an organized weight loss program during their weight loss (55.9% vs. 24.7%, p < .001) and to report improving personal esteem as a motivator (51.2% vs. 35.1%, p = .01). Men were more likely than women to report eating food from convenience stores at baseline (22.1% vs. 13.2%, p = .05) and throughout the study but otherwise reported similar meal patterns (ps > .05). Men reported higher energy intake than women while physical activity was similar. Although more men self-directed their initial weight loss and more women utilized organized weight loss programs, behaviors reported during weight loss maintenance were similar. Futures studies are needed to understand if these results generalize to other men who have successfully lost weight and are participants in other weight loss maintenance interventions.

Abstract
A 16-year-old female Vietnamese pot-bellied pig was euthanized after a period of inappetence and weight loss. Diffuse cystic endometrial hyperplasia and endometrial adenocarcinoma with metastasis to lymph nodes, liver, and lung were diagnosed. This report follows the recent description of cystic endometrial hyperplasia and uterine leiomyomas in 3 aged female Vietnamese pot-bellied pigs. The findings in this report and previous reports suggest that pigs may develop some similar age-related uterine lesions as do women.

Abstract
OBJECTIVE To test the efficacy of a weight loss intervention designed to appeal to men. METHODS A randomized trial tested the efficacy of the Rethinking Eating and FITness (REFIT) weight loss program compared to a wait-list control. The 6-month intervention was delivered via two face-to-face sessions followed by Internet contacts. REFIT encouraged participants to create calorie deficits by making six 100-calorie changes to their eating daily while increasing physical activity, and the program encouraged customization through selection of specific diet strategies evaluated each week. RESULTS Participants (N = 107, 44.2 years, 31.4 kg/m(2) , 76.6% white) were randomized into the study, and 90.6% provided data at 6 months. REFIT participants lost -5.0 kg (95% CI: -6.1, -3.9) at 3 months, which was maintained through 6 months (-5.3 kg, 95% CI: -6.5, -4.2); this was greater than the control group (p < 0.001; 6 months: -0.6, 95% CI: -1.8, 0.5). More REFIT participants (49%) achieved a 5% weight loss than control participants (19%; OR 9.4; 95% CI: 3.2, 27.4). An average of 11.2 (±2.7) of 13 of the online intervention contacts were completed. CONCLUSIONS The novel REFIT intervention produced clinically significant weight losses. This approach holds promise as an alternative to traditional behavioral therapy for men.

Abstract
This analysis investigated if changes in autonomous or controlled motivation for participation in a weight loss program differed between individuals offered a financial incentive for weight loss compared to individuals not offered an incentive. Additionally, the same relationships were tested among those who lost weight and either received or did not receive an incentive. This analysis used data from a year-long randomized worksite weight loss program that randomly assigned employees in each worksite to either a low-intensity weight loss program or the same program plus small financial incentives for weight loss ($5.00 per percentage of initial weight lost). There were no differences in changes between groups on motivation during the study, however, increases in autonomous motivation were consistently associated with greater weight losses. This suggests that the small incentives used in this program did not lead to increases in controlled motivation nor did they undermine autonomous motivation. Future studies are needed to evaluate the magnitude and timing of incentives to more fully understand the relationship between incentives and motivation.

Abstract
OBJECTIVES We examined whether adding behavioral weight loss strategies could improve the outcomes of a community weight loss campaign. METHODS Shape Up RI is a 12-week, online, team-based program for health improvement in Rhode Island. In study 1, we randomly assigned participants to the standard Shape Up RI program or to the program plus video lessons on weight loss. In study 2, we randomly assigned participants to the standard program or to the program plus video lessons; daily self-monitoring of weight, eating, and exercise; and computer-generated feedback. RESULTS Adding video lessons alone (study 1) did not result in significantly improved weight loss (2.0 ±2.8 kg vs 1.4 ±2.9 kg; P = .15). However, when the video lessons were supplemented with self-monitoring and feedback (study 2), the average weight loss more than doubled (3.5 ±3.8 kg vs 1.4 ±2.7 kg; P < .01), and the proportion of individuals achieving a weight loss of 5% or more tripled (40.5% vs 13.2%; P < .01). Participants in study 2 submitted self-monitoring records on 78% of days, and adherence was significantly related to outcome. CONCLUSIONS Adding behavioral strategies to community campaigns may improve weight loss outcomes with minimal additional cost.

Abstract
OBJECTIVE Most Americans do not meet physical activity recommendations. Statewide campaigns can effectively increase activity levels. Reported herein are physical activity outcomes from Shape Up Rhode Island (SURI) 2007, a statewide campaign to increase steps through team-based competition. Given the importance of social networks in behavior change, this paper focused on the effects of team and team characteristics on activity outcomes. METHOD For 16weeks, 5333 adults comprising 652 teams wore pedometers and reported their steps online. RESULTS Participants' daily steps increased from 7029(3915) at baseline to 9393(5976) at SURI end (p<0.001). There was a significant intraclass correlation for step change among team members (ICC=0.09); thus, an individual's change in steps was influenced by what team they were on. Moreover, baseline team characteristics predicted individual step change; being on a more active team was associated with greater increases in activity for individual members (p<0.001), whereas being on a team with a broad range of steps was associated with smaller changes in activity for individual members (p=0.02). CONCLUSION These findings are the first to suggest that team members influence individual activity outcomes in team-based statewide campaigns. Future research should explore ways to use social network factors to enhance team-based physical activity programs.

Abstract
Given the epidemic of obesity, approaches to weight loss that can be applied on a community, state, or national level are needed. We report results from Shape Up Rhode Island 2007 (SURI), a statewide Internet-based program involving team-based competition to increase physical activity and achieve weight loss. A total of 4,717 adults (84% women; mean BMI = 29.6 kg/m(2)) enrolled in the 16-week weight loss competition of SURI and 3,311 completed at least 12 weeks. Completers reported losing 3.2 +/- 3.4 kg, and 30% achieved a clinically significant weight loss of >or=5%. Although modest, these weight losses shifted the BMI distribution from a mean BMI of 29.4 to a mean of 28.2 kg/m(2) and reduced the population that was obese from 39 to 31%. More conservative intent-to-treat analyses and analysis of 132 participants with objective weights still showed a significant reduction in BMI of -0.8 units. These findings suggest that statewide weight loss campaigns can produce modest weight losses in large numbers of participants. These data provide a benchmark that can be used for comparisons with other statewide campaigns. Research on ways to improve such campaigns is needed.

Abstract
PURPOSE The primary goal of the Genetics of Generalized Osteoarthritis (GOGO) study is to identify chromosomal regions associated with increased susceptibility to generalized osteoarthritis (OA). Here we describe the study design and phenotype of the 2728 participants from the 1145 families recruited for this study. METHODS GOGO is an investigator-initiated collaboration involving seven clinical academic sites and sponsored by GlaxoSmithKline. Family ascertainment was carried out between 1999 and 2002. A qualifying family required self-reported Caucasian ethnicity and at least two affected siblings with clinical hand OA. We hypothesized that this clinical phenotype would facilitate identification of participants with multijoint radiographic OA (rOA) in and beyond the hand. The "gold standard" case definition, however, was based on rOA (Kellgren-Lawrence grade > or =2) involving > or =3 hand joints distributed bilaterally and including at least one distal interphalangeal joint, with two of the three involved joints within a joint group (distal interphalangeal, proximal interphalangeal, or carpometacarpal). Radiographs of hips, knees and spine were also obtained. Additional siblings and living parents from qualifying families, both affected and unaffected, were invited to participate. RESULTS A total of 2706 participants had complete clinical and radiological examination data. Of these, 2569 participants met clinical examination criteria for affected status; while 1963 (73%) participants met the prespecified radiographic criteria for affected status. This corresponded to a total of 707 families with at least two affected siblings that met the hand rOA criteria. Of those individuals with rOA of the hand, the frequency of rOA at other sites was highest for the knee (51%) and spine (54%), and less common for the hip (25%). Concordance rates among hand affected siblings were greatest for spine (36%) followed by knee (31%) and hip (9%); a total of 53% of the affected sib pairs were concordant for specific patterns of generalized rOA involving the hand and large joints (knees, hips or spine). CONCLUSIONS GOGO represents a large multicenter collection of families with multiple joint OA that have been characterized both clinically and radiographically. The GOGO study will employ a comprehensive strategy for genetic screening based upon both qualitative and quantitative radiographic trait analyses, circulating biomarkers in a quantitative trait-based analysis, fine mapping, and candidate gene analysis. This sample should provide sufficient power to detect linkage to OA associated genes.

Abstract
OBJECTIVE To determine whether an inactivated culture of a microcin-producing avian Escherichia coli was capable of killing Salmonella isolates from reptiles in an in vitro test system. SAMPLE POPULATION 57 Salmonella isolate from reptiles. PROCEDURE A wild-type avian E. coli electrotransformed with a plasmid coding for the production of microcin 24 was tested in an in vitro microassay system for its ability to kill 57 Salmonella spp isolated from reptiles. The reptile population included snakes, iguana, frilled lizards, turtles, other lizards, and unspecified reptiles. RESULTS 44 of the Salmonella isolates were inhibited strongly, compared with the in vitro assay controls; 12 had weak inhibition, and 1 was not inhibited by the microcin-producing E. coli. Thirteen of the 57 isolates had resistance to at least 1 antibiotic, primarily streptomycin. There were 9 O serogroups identified in the 57 isolates, with serogroup H being the most prevalent (18 to 57). CONCLUSION AND CLINICAL RELEVANCE Antibiotics are not recommended to eliminate Salmonella organisms from reptiles because of the development of antibiotic resistance. Further studies are necessary to determine whether the use of microcin-producing bacteria will be effective in controlling Salmonella infections in companion reptiles.

Abstract
BACKGROUND/PURPOSE Acute appendicitis is common, frequently atypical, challenging, and still associated with significant morbidity. Despite major technologic advances, appendicitis remains a primarily clinical diagnosis. Therefore, no relevant anamnestic information should be overlooked. Surprisingly, the relationship between heredity and appendicitis is seldom considered. Because of the potential clinical importance of the family history, the authors addressed this question prospectively over a 52-month period in a practice that includes the majority of pediatric patients with appendicitis in the region. METHODS Family histories were obtained in a standardized manner, focusing on first-degree relatives. Children with incomplete family information were excluded. Patients (ages 2(1/2) to 19 years) were divided into 3 groups: group A, children who underwent an appendectomy (n = 166); group B (first control), children who presented with an acute abdomen and suspected appendicitis but did not undergo an appendectomy (n = 117); group C (second control), children who were seen in the practice for unrelated conditions (n = 141). RESULTS A positive parental history was obtained from 59 patients (36%) in group A, 24 patients (21%) in group B, and 20 patients (14%) in group C, and the odds ratios (ORs) were 2.0 (P =.035) and 2.9 (P <.001) for groups A versus B and A versus C, respectively. Of the 13 patients whose sibling had had acute appendicitis, 9 were in group A versus 2 each in groups B and C, and the OR for any family history (siblings, parents) in groups A versus B was 1.9 (P =.028) and for groups A versus C was 2.9 (P < 0.001). Appendicitis was histologically confirmed in 93% of children in group A. CONCLUSIONS Heredity is a significant factor in pediatric patients who have appendicitis. Children who have appendicitis are twice as likely to have a positive family history than are those with right lower quadrant pain (but no appendicitis) and almost 3 times as likely to have a positive family history than are surgical controls (without abdominal pain). Because of its potential value in changing the threshold for intervention, a careful family history should be obtained for every child in whom acute appendicitis is suspected.

Abstract
OBJECTIVE To compare IVF outcomes between infertile African American and white women. DESIGN Retrospective cohort study. SETTING Hospital-based IVF practice. PATIENT(S) Women undergoing IVF procedures between November 1996 and June 2000. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Implantation and pregnancy rates. RESULT(S) There were 24 African American and 273 white women < or =40 years of age who underwent 25 and 333 IVF cycles, respectively. African American women were more likely to have had tubal factor as a primary diagnosis, to have had a child, and to have undergone fewer previous assisted reproductive technology (ART) cycles as compared to white women. No differences between the two groups for clinical variables were noted with the exception of body mass index (BMI [kg/m(2)], 27.1 in African Americans vs. 24.8 in whites). Implantation rates were higher in African American than in white women (35% vs. 23%, respectively). Pregnancy rates were 71% in African Americans and 48% in whites. After adjustment for tubal factor, BMI, and parity, the odds ratio for pregnancy in African American women versus white women increased from 2.6 to 3.3. CONCLUSION(S) This is the first study to demonstrate a significantly higher clinical pregnancy rate in African American women as compared to white women undergoing ART. These data strongly contradict a recent study comparing the same two groups of women undergoing ART. We urge other ART centers to report their data pertaining to race.

Abstract
The objective of this study was to examine and characterize limb-threatening lower extremity wound or soft tissue complications after coronary artery bypass (CABG) and determine risk factors for their cause. While minor wound problems of the leg after CABG are not uncommon, serious limb-threatening complications, though less frequent, do occur and are often de-emphasized in the surgical literature. A review of 1090 consecutive CABG procedures performed from January 1, 1995 through December 31, 1995 was instituted, which screened for limb-threatening lower extremity wound or soft tissue complications defined as wounds that: required additional surgery for treatment; prolonged the length of stay; or which required lengthy home health nursing for treatment. Minor lymph leaks, leg swelling, infections or wound problems treated as an outpatient were excluded. Of 1090 patients, 54 (5.0%) experienced a limb-threatening lower extremity complication. Complications were categorized as vein harvest incision non-healing (n = 36, 66.7%), decubitus ulceration (n = 11, 20.4%), forefoot ischemia/embolization (n = 10, 18.5%), groin hematoma/abscess (n = 6, 11.1%), severe cellulitis (n = 3, 5.6%), or a combination (n = 12, 22.2%). Statistically significant risk factors by univariate and bivariate analysis for a complication included older age (68 years vs 62 years, p = 0.007), female sex (57% vs 28%, p < 0.001), diabetes (57% vs 33%, p = 0.005) and longer pump time (129 min vs 114 min, p = 0.009). These complications necessitated five major lower extremity amputations and nine revascularization procedures. Chronic lower extremity ischemia from peripheral vascular disease (PVD) was a major contributing factor for the development of wounds in at least 23 (42.6%) of these patients, though suspected in only 10 (43.5%) preoperatively. A non-healing vein harvest incision below the knee of a patient retrospectively found to have inadequate distal circulation for healing occurred in 17 (31.5%) of the total 54 cases. It was concluded that non-healing vein incisions, decubitus ulcers and forefoot ischemic lesions frequently occurring in older diabetic females with undetected pre-existing PVD, comprise the majority of limb-threatening leg complications after CABG. Nearly one-third of the complications may have been avoided had the vein harvest incision not been made at the ankle of a patient with unappreciated PVD.

OBJECTIVE The purpose of this study was to test the ability of a clearly defined classification system for electronic fetal heart rate monitoring to predict early neonatal outcome. STUDY DESIGN All labors of women with singleton pregnancies > or = 32 weeks' gestation electronically monitored at 2 institutions were examined. Tracings in the final hour before delivery were defined as normal, fetal stress, or fetal distress. After delivery, Apgar scores, cord blood gas values, and admission to the neonatal intensive care unit were examined as measures of early neonatal outcome. RESULTS Among the 898 patients who qualified for study, 627 (70%) had tracings classified as normal, 263 (29%) had tracings classified as fetal stress, and 8 (1%) had tracings classified as fetal distress. There was a significant worsening of neonatal outcome across these 3 groups with regard to depressed Apgar scores 1 minute (5.1%, 18.3%, and 75.0%; P <.05), depressed Apgar scores at 5 minutes (1.0%, 3.8%, and 37.5%; P <.05), and admission to the neonatal intensive care unit (5.6%, 10.6%, and 37.5%; P <.05). There was also a progressive worsening of cord blood pH (7.27 +/- 0.06, 7.21 +/- 0.08, and 7.06 +/- 0.14; P <.05), a progressive increase in PCO (2) (53.39 +/- 8.34 mm Hg, 58.51 +/- 10.55 mm Hg, and 78.31 +/- 20.35 mm Hg; P <.05), and a progressive decline in base excess (-3.18 +/- 2.02 mEq/L, -5. 11 +/- 3.11 mEq/L, and -9.07 +/- 4.59 mEq/L; P <.05). CONCLUSION This simple classification system for interpreting fetal heart rate tracings accurately predicts normal outcomes for fetuses as well discriminating fetuses in true distress. Further, it identifies an intermediate group of fetuses with a condition labeled fetal stress who might benefit from additional evaluation and possibly from expeditious delivery.

Abstract
Concerned about the inadequacy of a centralized database and the importance of low morbidity and mortality on carotid endarterectomy efficacy, the South Carolina Vascular Surgical Society prospectively instituted a computer registry for carotid procedures performed by its members, to establish a statewide standard of practice. From January 1994 through December 1997, 23 of the 30 physician members voluntarily registered data on 1652 carotid operations at 14 hospitals into a central database. Blinded results were reviewed biannually. Complete data (1995-1997) were available for 1199 cases. The patients tended to be >64 years old (72%), male (62%), and white (93%). Carotid endarterectomy was the most frequently performed operation (90%). Perioperative complications (< or = 30 days) occurred in 173 patients (14.4%), including stroke (n = 19; 1.6%), death (n = 8; 0.7%), and stroke/death (n = 25; 2.0%). Although 23 surgeons (77% of the society) contributed some data, only 10 surgeons (33%) contributed complete data on >10 patients/year. Despite biannual efforts to boost participation, case entry remained stable (1994, 358; 1995, 347; 1996, 425; and 1997, 427), representing about one-third of the estimated carotid procedures performed in the state during that period. The cost of the registry was approximately $11,500. Audit of 8 surgeons revealed a >95 per cent match against the statewide discharge database and low error rate versus independent medical record review. This experience confirms that excellent outcomes after carotid endarterectomy are not limited to a few select centers and can be accomplished by adequately trained surgeons in a variety of institutional settings. Incomplete physician participation, however, inevitably raises questions about the utility of such efforts. Until volunteer registries induce full participation by heightening perceived physician benefit, their role will remain limited for future outcomes research.

Abstract
Although the efficacy of carotid endarterectomy has been well established, nonendarterectomy procedures of the carotid bifurcation have only sporadically been reported. Of 334 consecutive nontraumatic carotid procedures performed on 321 patients from July 1992 until May 1997, 306 (91.6%) were carotid endarterectomies, 14 (4.2%) were carotid-subclavian bypasses/transpositions, and 14 (4.2%) were nonendarterectomy procedures of the carotid artery. These latter 14 cases (nine females and five males; mean age, 63 years) were all symptomatic (neurological or painful mass) and included carotid kink/coil resection (n = 3; 0.9%), endarterectomy and vertebral transposition (n = 2; 0.6%), carotid aneurysm resection (n = 2; 0.6%), carotid body tumor resection (n = 2; 0.6%), carotid stump ligation/external endarterectomy (n = 1; 0.3%), infected/bleeding carotid patch removal with vein graft replacement (n = 1; 0.3%), saphenous vein graft replacement (n = 1; 0.3%), carotid dilatation for fibromuscular dysplasia (n = 1; 0.3%), and descending aorta to carotid bypass (n = 1; 0.3%). With 30 day follow-up complete for all 334 carotid operations, 10 perioperative strokes (2.9%) and five deaths (1.5%) occurred for a combined stroke/death rate of 3.3 per cent. Of the 14 nonendarterectomy carotid artery operations, there were no strokes or deaths; with mean follow-up of 13 months, 13 patients (92.9%) are asymptomatic, patent, and disease-free. Three severe transient cranial nerve (CN) neuropraxias (21.4%), one myocardial infarction (7.1%), and one late death (mesenteric ischemia at 2 months), however, occurred. Although no statistical differences in stroke, death, and stroke/death occurred between the endarterectomy versus the nonendarterectomy group, transient CN injury was more common in the nonendarterectomy group (21.4% versus 4.1%; P = 0.027). Although nonendarterectomy procedures of the carotid bifurcation are infrequently needed, they seem safe, effective, and indicated in selected patients, despite a higher incidence of transient CN injury.

Abstract
OBJECTIVE To investigate the effect of improved air quality on IVF and subsequent embryo development. DESIGN Retrospective cohort study. SETTING Hospital-based IVF facility composed of an anteroom, a cleanroom, and an adjacent operating room. PATIENT(S) Two-hundred seventy-five couples requesting IVF between 1993 and 1997. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Particle counts (sizes 0.3, 0.5, 1.0, and 5.0 microm); IVF rates; and embryo quality (stage and grade). RESULT(S) Clinical pregnancy rates decreased from 35% in 1993 to 16% in 1994 (numerous construction odors were detected during 1994) and increased steadily after the cleanroom was built (rates for 1995-1997 were 20%, 32%, and 59%, respectively). Fertilization rates decreased between 1993 (74%) and 1994 (60%) and then steadily increased after cleanroom installation (62% in 1995, 71% in 1996, and 69% in 1997). The proportion of embryos past the four-cell stage decreased from 66% in 1993 to 61% in 1994 but then increased steadily in the years after the cleanroom was built (78%, 77%, and 83% in 1995, 1996, and 1997, respectively). During the same 5-year period, there were no differences in embryo quality or number of embryos transferred. CONCLUSION(S) Construction of a Class 100 cleanroom improved air quality and IVF rate and increased the number of embryos past the four-cell stage available for transfer.

Abstract
OBJECTIVE To determine the usefulness of and cost-effectiveness of antisperm antibody testing in the prediction of poor fertilization rates in couples undergoing IVF. DESIGN Retrospective cohort study. SETTING A hospital-based reproductive endocrinology and infertility practice. PATIENT(S) Male partners of 251 couples undergoing IVF between 1992 and 1997. MAIN OUTCOME MEASURE(S) Fertilization rates in couples undergoing conventional IVF. RESULT(S) One hundred nineteen couples were evaluated for antisperm antibodies; fertilization rates were similar in those couples whose husbands were and were not tested (64% versus 68%). Antisperm antibodies were detected in 16 men. Four (25%) of the 16 couples whose husbands had antisperm antibodies fertilized < or = 50% of oocytes, compared with 31 (30%) of the 103 couples whose husbands did not have these antibodies. Overall, 21 couples (8.4%) experienced complete fertilization failure. In a program that included antisperm antibody testing for selected couples and intracytoplasmic sperm injection (ICSI) for those who tested positive, it would cost $11,735 to prevent a fertilization failure (assuming ICSI were 100% effective), whereas it would cost $9,250 to perform ICSI in a second IVF cycle for those who initially failed. CONCLUSION(S) In this practice setting, antisperm antibody testing has low sensitivity in predicting low or no fertilization and does not appear to be cost-effective when selectively ordered as part of an IVF workup.

Abstract
Lower-extremity limb salvage should parallel infrainguinal bypass graft patency. To determine factors associated with limb loss despite a patent bypass, we reviewed 191 consecutive infrainguinal bypasses in 158 patients followed prospectively over 42 months. In this series of 176 (92%) vein grafts, 15 (8%) expanded polytetrafluoroethylene grafts, 122 (64%) tibial artery bypasses, and 170 (89%) bypasses placed for limb salvage, 29 major lower-extremity (above-knee or below-knee) amputations were performed in 29 patients, 12 because of ischemia after graft thrombosis and 17 (9% of series) due to progression of soft tissue infection/necrosis despite a functioning bypass. Primary and secondary 36-month vein graft patencies by life-table analysis were 61 per cent and 81 per cent, respectively. When the 17 cases of limb loss were compared to the rest of the series, nonstatistically significant variables included male sex [11 (65%) vs 79 (56%); P = 0.608] and diabetes [12 (71%) vs 80 (57%); P = 0.310]. Statistically significant variables included black race [9 (53%) vs 39 (28%); P = 0.048]; chronic renal failure [6 (35%) vs 12 (9%); P = 0.005], placement to a tibial/pedal artery [15 (88%) vs 107 (62%); P = 0.034], distal anastomosis to the anterior tibial/dorsalis pedis (AT/DP) artery [8 (47%) vs 27 (16%); P = 0.004], and grafts requiring late revision [7 (41%) vs 22 (13%); P = 0.006]. Thirteen (76%) extremities had an intact pedal arch. Nine amputations were performed within 30 days (early group), and eight were performed from 45 days to 20 months (median, 8 months) after bypass placement (late group). The most common primary causes of limb loss in the early group were overwhelming progression of soft-tissue infection despite patent bypass (n = 4; 44%) and insufficient runoff in the foot (n = 3; 33%). In the late group, amputation most often followed long treatment of a chronic proximal diabetic neuropathic foot ulcer with osteomyelitis. Five (63%) grafts in this group were anastomosed to the AT/DP arteries. These data suggest that patients with chronic renal failure, chronic neuropathic heel ulcers, and an AT/DP bypass are at greater risk for amputation despite a working bypass, especially if the graft develops a hemodynamically significant stenosis. Careful judgment and patient selection under these circumstances are thus justified.

Abstract
PURPOSE To evaluate, in a group of technically high-risk patients, the results of infrainguinal revascularization using a conduit constructed with endarterectomized superficial femoral artery (SFA) and available arm or saphenous vein. METHODS Of 237 consecutive lower extremity vein graft bypass procedures performed in 195 patients from July 1992 through August 1996, 15 SFA eversion endarterectomies (in 10 men and five women; median age, 70 years) were performed and used as a composite bypass conduit with available autogenous vein for the treatment of limb-threatening ischemia. In each case, an occluded SFA was divided 8 to 15 cm distal to its origin, proximally endarterectomized, and sewn end-to-end to a segment of vein to provide adequate conduit length for bypass grafting. Indications for this technique were unavailability of vein as a result of failed previous bypass grafting (n = 10) or previous coronary artery bypass grafting (n = 5). Veins were sewn distally to a below-knee popliteal artery (n = 4; 27%) or tibial artery (n = 11; 73%). RESULTS Primary patency, secondary patency, and limb salvage rates at 36 months by life table analyses for the 237 grafts were 62.3%, 81.0%, and 77.2%, respectively. The 15 composite SFA-vein bypass grafts had 36-month primary patency, secondary patency, and limb salvage rates of 60.0%, 72.0%, and 65.9%, respectively (mean follow-up, 15 months). Currently, eight of these patients (53%) have patent bypass grafts; two (13%) died at 4 and 18 months after the operation with patent grafts; two (13%) underwent amputations for progressive foot gangrene despite a patent bypass graft; and three (20%) had grafts that thrombosed at 4, 5, and 10 months. Typical hyperplastic intrinsic graft-threatening stenoses developed in two patients (13%) in the SFA segment at 4 and 8 months; they were discovered by routine duplex scan surveillance. CONCLUSION Composite SFA eversion endarterectomy/vein graft conduits yield acceptable results, behave similarly to other autogenous conduits used for technically high-risk infrainguinal revascularization, and are beneficial when autogenous vein is limited.

Abstract
Many bone marrow cytogenetic abnormalities in acute myelogenous leukemia (AML) are tumor specific, clonal, nonrandom, and related to prognosis; it has been hypothesized that they may be markers of exposure to etiological agents. A previous report from our institution revealed several such associations; the purpose of the current study was to determine whether previous findings were present in a new group of patients. Subjects included 84 newly diagnosed AML patients (French-American-British M1 and M2); exposure data were gathered using self-report questionnaires at the time of registration. Two sets of comparisons were made: (a) patients with all (AA) or some (AN) cytogenetically abnormal cells versus those with normal karyotypes (NN) and (b) patients with specific abnormalities [-5/5q-, -7/7q-, +8, t(8;21)] versus all others. Odds ratios (ORs) were 4.64 for the association between prior cytotoxic therapy and -5/5q- and 6.38 for the association with -7/7q-, but were <1.00 for +8 and t(8;21). There were no ORs > 2.0 for specific abnormalities in any of the other exposures evaluated (cigarette smoking, alcohol use, occupational exposure to organic chemicals, paints, or pesticides/herbicides), with the exception of exposure to paints and -7/7q- (OR, 7.50). The ORs for AA/AN versus NN patients were 1.43 and 3.81 for smoking and alcohol use, and weak dose-response trends were present. The most consistent positive associations between the two series were for prior cytotoxic therapy (-5/5q-; -7/7q-), cigarette smoking (AA/AN versus NN) and alcohol use (AA/AN versus NN). Reasoning from the known association between prior cytotoxic therapy and -7/7q-, we would have predicted relatively high ORs (> 4.0) if specific abnormalities acted as markers for the exposures assessed, but none were present. However, in both series, AA/AN patients were more likely to smoke and use alcohol than were NN patients, and weak dose-response patterns were present for both. This finding suggests that both smoking and alcohol use may play a role in the pathogenesis of cytogenetic abnormalities in AML-M1/M2; however, the mechanism by which they work and whether they are involved in the etiology of these diseases remain unclear.

Abstract
These data demonstrated that participants in our teen pregnancy program had better birth outcomes than comparable teens who did not participate in the program. Based on number of NICU admissions and lengths of stay, we estimate that this program provided, through the reduction of poor birth outcomes, potential cost savings of $890,000 over four years.

Abstract
A prospective (cohort) study was conducted to determine the incidence of low antithrombin III (AT III) levels and the association with selected clinical variables in adult trauma patients. One hundred sixty AT III levels were obtained on 50 consecutive trauma admissions to a community-based level I trauma center. Antithrombin III levels were drawn as soon after admission as possible and every other day thereafter. Thirty-one patients (62%) had at least one low AT III level (< 80%), whereas 15 concurrently drawn control levels were all > or = 90%. Low AT III levels were more common in patients with one or more of the following: base deficit less than -4 (39% vs. 0, p = 0.002); Injury Severity Score > 15 (48% vs. 16%, p = 0.04); and blood transfusion (32% vs. 5%, p = 0.04). All other variables (shock, surgical intervention, subcutaneous heparin, and sequential compression devices) were not statistically significant, although all six patients with shock had low levels. In conclusion, over 60% of adult trauma patients had low AT III levels at some time during hospitalization and these patients were clearly more severely injured. Further studies are required to determine if these patients are more susceptible to thromboembolic phenomena.

Abstract
BACKGROUND AND DESIGN Patients with human immunodeficiency virus (HIV) infection can develop severe psoriasis, which is difficult to treat using conventional therapy. Anecdotal case reports have suggested that administration of zidovudine can improve psoriasis in the HIV-infected patient. An open-label study was conducted to determine the safety and effectiveness of zidovudine therapy in 24 patients with HIV-associated psoriasis and to correlate response with laboratory and clinical variables. RESULTS Of 19 evaluable patients, 90% had either partial (58%) or complete (32%) improvement of their HIV-associated psoriasis during zidovudine therapy. Greater than 75% reduction in the body surface area involved was positively associated with antigenemia and an age younger than 30 years. CONCLUSIONS Zidovudine therapy, at a dosage of 1200 mg/d, appears to be beneficial in the treatment of HIV-associated psoriasis, although long-term relapses occurred and the associated arthritis did not improve.

Abstract
This study was designed to assess the relative contributions of HIV transmission category and immunodeficiency to the risk of HIV-related diarrhea. We reviewed the medical records of 169 HIV-infected non-AIDS patients seen between 1986 and 1990 at the Houston VA Special Medicine Clinic. The prevalence of diarrhea at any given clinic visit ranged from 3% to 7%. Diarrhea was three times more common in homosexual/bisexual men [odds ratio = 3.0 (1.01-9.53)], and this pattern persisted when stratified by CD4 count. Previous studies have focused mainly on the detection of enteric organisms in patients with HIV-related diarrhea. Studies of the temporal relationships between sexual practices, enteric pathogens, diarrhea, and immunodeficiency are needed to clarify the pathogenesis of HIV-related diarrhea.

Abstract
Adverse health effects associated with intrauterine cocaine exposure (prematurity and its associated morbidity, intrauterine growth retardation, possible risk of sudden infant death syndrome) are based on studies from large urban hospitals, but few data exist from other sources. The current study, set in a community hospital, was designed to (1) estimate the prevalence of maternal cocaine use at delivery, (2) describe neonatal outcomes, and (3) evaluate physiological growth in exposed children. The study was conducted over 30 months (total births were 14,074) at The Children's Hospital of Greenville Memorial Hospital, the major source of neonatal care for Greenville County, South Carolina (1990 population: 320,000). A child was considered exposed to cocaine if there was documented evidence of use in the mother's medical record or if one member of the pair had a positive urine drug screen. Growth data were abstracted from clinical records. Overall prevalence of exposure was 1.0%. Of the 137 subjects (89, positive urine drug screen; 48 self-reported exposure), 21 (15%, 95% confidence interval, 9% to 21%) were premature (gestational age < 37 weeks) and 2 died of sudden infant death syndrome. Mean age- and sex-adjusted percentiles for weight, length, and head circumference increased from 23%, 29%, and 18%, respectively, at birth to 43%, 49%, and 54% in children followed for 12 months; however, 50% of the cohort were lost to follow-up, and these children were smaller at birth than those under active follow-up. Rates of prematurity and infant death were similar to those reported in urban hospitals.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE To develop a simple clinical staging system based on CD4 count and clinical variables that predicts progression to AIDS in HIV-infected non-AIDS patients. DESIGN Retrospective cohort study. SETTING A primary care outpatient clinic for HIV-infected patients at a VA Medical Center. PATIENTS One hundred seventy-six HIV-infected non-AIDS patients seen at the Houston VA Special Medicine Clinic between January 1986 and December 1990 and followed for a mean of 22 months. Fifty-four patients (31%) progressed to AIDS during follow-up. MEASUREMENTS The medical records were reviewed, and data corresponding to the initial (baseline) clinic visit and subsequent six-month visits were extracted. MAIN RESULTS "Predictive" baseline variables (i.e., those associated with progression to AIDS) were first identified and then examined in Cox proportional hazards modeling. In the final model, CD4 category, oral thrush, and night sweats made significant independent contributions. A three-stage prognostic system was constructed by assigning points to the three variables: CD4 > 500 cells/mm3 = 0; 500 > or = CD4 > or = 200 = 1; CD4 < 200 = 2; presence of oral thrush = 1; presence of night sweats = 1. Stages were assigned as follows: stage I = 0 points, stage II = 1-2 points, and stage III = 3-4 points. The proportions of patients who progressed to AIDS were: stage I, 6/39 (15%); stage II, 31/106 (29%); and stage III, 17/31 (55%). CONCLUSIONS These results demonstrate that simple, clinically sensible prognostic staging systems that predict progression to AIDS can be constructed using CD4 count and clinical variables.
