Barriers and facilitators to implementing a multilevel, multicomponent intervention promoting colorectal cancer screening in health centers: a qualitative study of key informant perspectives. BMC Health Serv Res 2024; 24:404. [PMID: 38553723 PMCID: PMC10981354 DOI: 10.1186/s12913-024-10749-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Accepted: 02/19/2024] [Indexed: 04/01/2024] Open
Abstract
BACKGROUND Colorectal cancer (CRC) continues to be a major cause of death in the U.S. despite the availability of effective screening tools. U.S. Latinos have lower rates of CRC screening and higher rates of death due to colorectal disease compared to non-Hispanic whites. Federally Qualified Health Centers (FQHCs) serve medically underserved populations, including many Latino patients. Given the low CRC screening rates, identifying culturally sensitive and cost-effective methods of promoting screening is a priority for many FQHCs. METHODS We interviewed FQHC leaders and providers using the Consolidated Framework for Implementation Research (CFIR) to identify barriers and facilitators to implementation of a multilevel, multicomponent (ML-MC) CRC screening intervention (i.e., promotor navigation and group-based education) in FQHCs. A rapid qualitative analysis approach was used to identify themes organized according to the following CFIR constructs: intervention characteristics, outer and inner settings, and characteristics of the individual. RESULTS We completed interviews with 13 healthcare professionals in leadership positions at six FQHCs. The participating FQHCs perceived the ML-MC screening CRC program as feasible and expressed interest in implementing the program at their sites. Facilitators included financial incentives for increasing screening rates, the need for patient education programming, and involving promotores to support the work of clinical teams. Barriers included concerns about available resources to implement new programs, lack of federal reimbursement for health education, competing priorities of other health concerns, and the need for more resources for confirmatory screening and treatment following a positive screen. CONCLUSIONS FQHCs provide essential primary care to millions of underserved patients in the U.S. and have the ability and motivation to provide screenings for colorectal cancer. Partnering with an academic institution to deliver a group-based, promotor-led CRC screening intervention for patients not up to date with screening could help increase screening rates. By identifying the specific barriers and facilitators to implementing CRC intervention, findings suggest that group-based, promotor-led interventions are a promising approach.

Abnormal Colorectal Cancer Test Follow-Up: A Quality Improvement Initiative at a Federally Qualified Health Center. J Prim Care Community Health 2024; 15:21501319241242571. [PMID: 38554066 PMCID: PMC10981848 DOI: 10.1177/21501319241242571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 03/07/2024] [Accepted: 03/08/2024] [Indexed: 04/01/2024] Open
Abstract
INTRODUCTION/OBJECTIVES Colonoscopy completion rates after an abnormal fecal immunochemical test (FIT) are suboptimal, resulting in missed opportunities for early detection and prevention of colorectal cancer. Patient navigation and structured follow-up may improve colonoscopy completion, but implementation of these strategies is not widespread. METHODS We conducted a quality improvement study using a Plan-Do-Study-Act (PDSA) Model to increase colonoscopy completion after abnormal FIT in a large federally qualified health center serving a diverse and low-income population. Intervention components included patient navigation, and a checklist to promote completion of key steps required for abnormal FIT follow-up. Primary outcome was proportion of patients achieving colonoscopy completion within 6 months of abnormal FIT, assessed at baseline for 156 patients pre-intervention, and compared to 208 patients during the intervention period from April 2017 to December 2019. Drop offs at each step in the follow-up process were assessed. RESULTS Colonoscopy completion improved from 21% among 156 patients with abnormal FIT pre-intervention, to 38% among 208 patients with abnormal FIT during the intervention (P < .001; absolute increase: 17%, 95% CI: 6.9%-25.2%). Among the 130 non-completers during the intervention period, lack of completion was attributable to absence of colonoscopy referral for 7.7%; inability to schedule a pre-colonoscopy specialist visit for 71.5%; failure to complete a pre-colonoscopy visit for 2.3%; the absence of colonoscopy scheduling for 9.2%; failure to show for a scheduled colonoscopy for 9.2%. CONCLUSIONS Patient navigation and structured follow-up appear to improve colonoscopy completion after abnormal FIT. Additional strategies are needed to achieve optimal rates of completion.

Abstract
Animals frequently make adaptive decisions about what to prioritize when faced with multiple, competing demands simultaneously. However, the proximate mechanisms of decision-making in the face of competing demands are not well understood. We explored this question using brain transcriptomics in a classic model system: threespined sticklebacks, where males face conflict between courtship and territorial defence. We characterized the behaviour and brain gene expression profiles of males confronted by a trade-off between courtship and territorial defence by comparing them to males not confronted by this trade-off. When faced with the trade-off, males behaviourally prioritized defence over courtship, and this decision was reflected in their brain gene expression profiles. A distinct set of genes and biological processes was recruited in the brain when males faced a trade-off and these responses were largely non-overlapping across two brain regions. Combined, these results raise new questions about the interplay between the neural and molecular mechanisms involved in decision-making.

Abstract
Objectives:
Existing sedentary behavior interventions have largely achieved modest results. Conventionally, interventions have attempted to reduce sedentary time using a full-day approach. An alternative strategy is to target specific periods when sedentary behavior is most prevalent. However, little is known when sedentary time is most likely to occur in adults. This study examined the day-of-the-week and time-of-the-day patterns of sedentary behavior among U.S. Hispanic/Latino adults.
Methods:
Participants (n=12,241) from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a multi-site prospective cohort study of Hispanic/Latino adults, were studied. Sedentary time was measured for one week using a hip-mounted accelerometer. Three sedentary metrics were quantified: total sedentary time, sedentary time in bouts ≥ 60 minutes, and number of sedentary breaks.
Results:
Temporal patterns across days of the week were statistically significant for all three sedentary metrics (Figure, Panels A-C, p < .001). Total sedentary time decreased from 719±2 mins/d on Mondays to 710±3 mins/d on Fridays the lowest and increased over weekends with Sundays (733±3 mins/d) the highest. Temporal patterns across 3-h periods of the day were statistically significant for all sedentary metrics (Figure, Panels D-F, p < .001). Time-of-the-day patterns had a U-curve pattern wherein adults were most sedentary late at night, became less sedentary throughout the day, reached peak activeness around noon, then became more sedentary into the evening. Day-of-the-week and time-of-the-day patterns were robust across age, employment, work shift, and acculturation subgroups.
Conclusions:
Mornings, evenings, and weekends were the most sedentary periods in this cohort of Hispanic/Latino adults, characterized by higher volumes of sedentary time, more prolonged sedentary bouts, and fewer sedentary breaks. These time periods should be considered as important windows for behavioral interventions targeting sedentary behavior.

Applying Implementation Mapping to Expand a Care Coordination Program at a Federally Qualified Health Center. Front Public Health 2022; 10:844898. [PMID: 35400046 PMCID: PMC8987275 DOI: 10.3389/fpubh.2022.844898] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Accepted: 02/28/2022] [Indexed: 11/13/2022] Open
Abstract
Background A large and growing percentage of medically underserved groups receive care at federally qualified health centers (FQHCs). Care coordination is an evidence-based approach to address disparities in healthcare services. A partnered FQHC established a care coordination model to improve receipt and quality of healthcare for patients most at risk for poor health outcomes. This care coordination model emphasizes identification and support of behavioral health needs (e.g., depression, anxiety) and two evidence-based behavioral health programs needs were selected for implementation within the context of this care coordination model. Implementation Mapping is a systematic process for specifying the implementation strategies and outcomes. The current case study describes the application of Implementation Mapping to inform the selection and testing of implementation strategies to improve implementation of two behavioral health programs in a Care Coordination Program at a partnered FQHC. Methods We applied Implementation Mapping to inform the development, selection and testing of implementation strategies to improve the implementation of two evidence-based behavioral health programs within a care coordination program at a partnered FQHC. Results Results are presented by Implementation Mapping task, from Task 1 through Task 5. We also describe the integration of additional implementation frameworks (The Consolidated Framework for Implementation Research, Health Equity Implementation Framework) within the Implementation Mapping process to inform determinant identification, performance and change objectives development, design and tailoring of implementation strategies and protocols, and resulting evaluation of implementation outcomes. Conclusions The current project is an example of real-world application of Implementation Mapping methodology to improve care outcomes for a high priority population that is generalizable to other settings utilizing similar care models and health equity endeavors. Such case studies are critical to advance our understanding and application of innovative implementation science methods such as Implementation Mapping.

Abstract
Clinical and public health translation of genomics could be facilitated by expertise from behavioral medicine, yet genomics has not been a significant focus of the Society of Behavioral Medicine (SBM). SBM convened a working group (WG) to lead a systematic exploration of members' views on: (a) whether SBM should give a higher priority to genomic translation and (b) what efforts, if any, should be made to support this increased engagement. The WG used a stepped process over 2 years that began by gaining input from SBM leadership regarding key issues and suggestions for approach, engaging a cross section of membership to expand and record these discussions, followed by systematic qualitative analyses to inform priority action steps. Discussions with SBM leaders and members suggested that genomics was relevant to SBM, particularly for junior members. SBM members' expertise in social and behavioral theory, and implementation study designs, were viewed as highly relevant to genomic translation. Participants expressed that behavioral and social scientists should be engaged in translational genomics work, giving special attention to health disparities. Proposed action steps are aligned with a "push-pull" framework of innovation dissemination. "Push" strategies aim to reach potential adopters and included linking members with genomics expertise to those wanting to become involved and raising awareness of evidence-based genomic applications ready for implementation. "Pull" strategies aim to expand demand and included developing partnerships with genomics societies and advocating for funding, study section modifications, and training programs.

Abstract
Abstract
Purpose: Impact of colorectal cancer (CRC) screening with the fecal immunochemical test (FIT) depends on completion of diagnostic colonoscopy after abnormal FIT, as failure to complete diagnostic colonoscopy is associated with 2.4 fold increased risk of CRC death. Colonoscopy completion after abnormal FIT ranges from 18% to 57% among Federally Qualified Health Centers (FQHCs) in San Diego County. Our goal is to report the initial successes and challenges of a multi-level, patient navigator (PN) led intervention to optimize colonoscopy completion after abnormal FIT faced largely by Hispanic/Latino patients in our geographic area. Methods: At a single primary clinic within a large FQHC in San Diego’s predominantly Latino community, we implemented a multi- component intervention to promote colonoscopy completion for patients with abnormal FIT led by a bilingual/bicultural PN. PN responsibilities included monitoring timely review of FIT results by ordering provider, results provision to patients, insurance authorization, facilitating referrals for GI consultation and colonoscopy scheduling. Health system barriers (such as failure to order colonoscopy) were addressed by having the PN prompt the relevant team member to complete required care steps. Patient barriers (such as understanding FIT results, procedure scheduling and fears) were addressed through phone and in-person encounters by the PN. Summary: During the period of March to August 2017, 45 patients had an abnormal FIT. Out of 45 patients, three were not eligible for navigation due to prior colonoscopy completion. Of the remaining 42, 26 did not complete colonoscopy (14 lost to follow-up, 4 pending GI consult, 4 pending colonoscopy, 4 declined). The PN directly interacted with 28 patients of which 16 (57%) successfully completed colonoscopy. These preliminary results show a low overall rate of colonoscopy completion (16/45=36%) with nearly one third of patients (14/45=31%) lost to follow-up. Conclusions: In our initial experience with a PN-led, multi-level intervention for promoting colonoscopy completion after abnormal FIT, 57% of patients who interacted with the PN completed a colonoscopy procedure. Challenges such as loss to follow up remain a barrier to intervention success. Our results suggest that multi-level interventions led by a PN have potential to optimize follow through of colonoscopy completion after abnormal FIT.

Cultural adaptation of 'Healthy Dads, Healthy Kids' for Hispanic families: applying the ecological validity model. Int J Behav Nutr Phys Act 2020; 17:52. [PMID: 32316983 PMCID: PMC7171778 DOI: 10.1186/s12966-020-00949-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Accepted: 03/27/2020] [Indexed: 12/22/2022] Open
Abstract
Background Healthy Dads Healthy Kids (HDHK) is a unique lifestyle obesity intervention for fathers and children that demonstrated weight loss among the fathers and behavior change among fathers and children in Australia. The program is gender-tailored to specifically target fathers for weight loss and 5–12 year old children for obesity prevention. The aim of this formative study was to examine an Expert Panel’s and Hispanic Family Panel’s perceptions about the program and suggestions for the cultural adaptation of HDHK for Hispanic families in southwestern US. Methods Forty-four Hispanic participants (22 fathers, 13 mothers and 9 children) made up the Family Panel. They participated in 1–5 study contacts (focus groups, online survey, and/or interviews). The scripts and qualitative guides assessed participants’ perceptions of the HDHK content and material using the Ecological Validity Model. Studies were conducted in English or Spanish, depending on the preference of the participant. Focus groups and interviews were audio-recorded, transcribed, translated, and thematically coded. Findings were reviewed with the Expert Panel who helped inform the cultural adaptation. Results 80% of parents were foreign-born, 57% spoke only Spanish at home, and 60% did not graduate from high school. Several themes emerged to inform the cultural adaptation of the program. Parents agreed with the HDHK goals and recommended the program place greater emphasis on parenting and limiting children’s screen time. Some mothers and fathers wanted greater mother engagement. Weekly videos and a Facebook group emerged as favorite alternative options to engage mothers. Greater promotion of familism (inclusion and impact on whole family) was recommended for the program goals and activities. Gender roles for mothers and fathers, and differences in how fathers interact with male and female children, emerged and should be considered in program activities. Several barriers to father engagement surfaced, including lack of time due to work schedules, physically demanding jobs, concerns of caring for children without mother, fathers’ current fitness/weight, and lack of knowledge of how to eat more healthfully. The reading level of the HDHK materials was too high for some parents. Conclusion Findings from these formative qualitative studies informed the cultural adaptation of HDHK for Hispanic families, to account for literacy level, cultural values, and barriers to participation and engagement.

Abstract
STUDY OBJECTIVES Activities throughout the day, including sleep, sedentary behavior (SB), light-intensity physical activity (LIPA), and moderate to vigorous physical activity (MVPA) are independently associated with cardiometabolic health. Few studies have examined interrelationships between sleep and 24-hour activity and associations with cardiometabolic risk. The objective of this study is to understand how replacing time in SB, LIPA, or MVPA with sleep impacts cardiometabolic risk. METHODS Women's Health Initiative OPACH Study participants (N = 3329; mean age = 78.5 ± 6) wore ActiGraph GT3X+ accelerometers 24 hours/7 days. Adjusted linear regression estimated the relationship between sleep duration and cardiometabolic markers. Separately for shorter (<8 hours) and longer (≥8 hours) sleepers, isotemporal substitution models estimated the cross-sectional associations with cardiometabolic markers with reallocating time in daytime activities to or from sleep. RESULTS Longer sleep duration was associated with higher insulin, HOMA-IR, glucose, total cholesterol, and triglycerides (all p < 0.05). The associations between sleep duration and C-reactive protein, waist circumference, and body mass index (BMI) were U-shaped (both p < 0.05). For shorter sleepers, reallocating 33 minutes of MVPA to sleep was associated with higher values of insulin, HOMA-IR, glucose, triglycerides, waist circumference, and BMI (0.7%-11.5%). Replacing 91 minutes of SB time with sleep was associated with lower waist circumference and BMI (-1.3%, -1.8%). For long sleepers, shifting 91 minutes of sleep to SB was associated with higher waist circumference and BMI (1.3%, 1.4%). CONCLUSIONS This is one of the first isotemporal analyses to include objectively measured sleep duration. Results illuminate possible cardiometabolic risks and benefits of reallocating time to or from sleep.

Abstract
UNLABELLED Primary care-based approaches to address concurrent obesity and cardiovascular disease risk factors (CVDRFs) that begin with a high intensity intervention that is subsequently decreased (i.e., stepped-down) if weight loss is achieved have not been rigorously examined. Our study is a 20-month, single-blind randomized controlled trial at five primary care clinics in San Diego, CA, in 2013, where 262 obese adults (aged 25-70 years; 32.1% male; 59.2% white) with at least one CVDRF were enrolled into planned care for obesity and risk reduction (PCORR) using a stepped-down approach or enhanced usual care (EUC). All patients received physician recommendations for weight loss and CVDRFs. EUC patients (n = 132) received an individual session with a health educator every 4 months. PCORR patients (n = 130) received individual and group sessions (in-person, mail, telephone, and email) in three steps, characterized by less contact if success was achieved. At 20 months, 40.7%, 23.8%, and 15.4% of PCORR patients were in steps 1, 2, and 3, respectively (25.2% were lost to follow-up). PCORR resulted in a between-group difference in reduction in body weight of 6.1% [95% CI, 5.3 to 6.9] compared to EUC 2.8% [95% CI, 2.0 to 3.6] p = 0.007, with a greater reduction in BMI (35.2 [95% CI, 34.4 to 35.9] to 33.7 [95% CI, 32.9 to 34.5] kg/m2) than EUC (36.0 [95% CI, 35.3 to 36.8] to 35.1 [95% CI, 34.3 to 35.9] kg/m2), as indicated by a significant treatment by time interaction (p = 0.009). PCORR resulted in greater weight loss over 20 months than EUC. TRIAL REGISTRATION ClinicalTrials.gov, NCT01134029.

Abstract
OBJECTIVES Usual physical activity (PA) is a complex exposure and typical instruments to measure aspects of PA are subject to measurement error, from systematic biases and biological variability. This error can lead to biased estimates of associations between PA and health outcomes. We developed a calibrated physical activity measure that adjusts for measurement error in both self-reported and accelerometry measures of PA in adults from the US Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a community-based cohort study. DESIGN Total energy expenditure (TEE) from doubly labeled water and resting energy expenditure (REE) from indirect calorimetry were measured in 445 men and women aged 18-74years in 2010-2012, as part of the HCHS/SOL Study of Latinos: Nutrition & Physical Activity Assessment Study (SOLNAS). Measurements were repeated in a subset (N=98) 6months later. METHOD Calibration equations for usual activity-related energy expenditure (AEE=0.90×TEE-REE) were developed by regressing this objective biomarker on self-reported PA and sedentary behavior, Actical accelerometer PA, and other subject characteristics. RESULTS Age, weight and height explained a significant amount of variation in AEE. Actical PA and wear-time were important predictors of AEE; whereas, self-reported PA was not independently associated with AEE. The final calibration equation explained fifty percent of variation in AEE. CONCLUSIONS The developed calibration equations can be used to obtain error-corrected associations between PA and health outcomes in HCHS/SOL. Our study represents a unique opportunity to understand the measurement characteristics of PA instruments in an under-studied Hispanic/Latino cohort.

Abstract
Hispanics/Latinos face specific sociocultural stressors associated with their marginalized status in the United States. While stress is known to cause poor sleep, the differential effects of the specific stressors faced by Hispanics/Latinos have not been evaluated. Using cross-sectional data from the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study, we conducted weighted generalized linear models to evaluate the associations of acculturation stress, ethnic discrimination, and chronic moderate/severe stress with self-reported sleep outcomes (insomnia symptoms, daytime sleepiness, sleep duration) in individual and aggregate models adjusted for site, socio-demographics, behavioral, and medical conditions. Participants included 5313 Hispanic/Latino adults; 43.5% ≥ age 45, 54.8% female, and 22.0% US-born. Chronic moderate/severe stress, ethnic discrimination, and acculturation stress were each positively associated with sleep. In the adjusted aggregate model, only chronic moderate/severe stress was associated with insomnia symptoms (exp(b) = 1.07 for each additional stressor, 95% CI = 1.05, 1.09). Both acculturation stress (exp(b) = 1.05 for each additional SD, 95% CI = 1.02, 1.10) and ethnic discrimination (exp(b) = 1.05 for each additional SD, 95% CI = 1.01, 1.08) were associated with daytime sleepiness. Each SD increase in ethnic discrimination related to a 16% and 13% increased prevalence of short (< 7 h) (RRR = 1.16, 95% CI = 1.02, 1.31) and long sleep duration (> 9 h) (RRR = 1.13, 95% CI = 1.00, 1.27), respectively. These associations were consistent across sex. Acculturation stress and ethnic discrimination are associated with poor sleep in Hispanics/Latinos. Future research should explore whether behavioral sleep interventions minimize the impact of sociocultural stressors on sleep. Latina/os face unique stressors associated with their marginalized status in the USA. We explored the association of sociocultural stressors with Latina/o sleep. Acculturation stress and ethnic discrimination were associated with daytime sleepiness. Only chronic psychosocial stress was associated with insomnia symptoms. Ethnic discrimination was associated with both short and long sleep duration.

Abstract
Background.
Screening for colorectal cancer (CRC) can reduce cancer incidence and mortality, but participation rates are low among underserved populations. Federally Qualified Health Centers (FQHCs) in many states have an opportunity to be at the vanguard of improving screening rates among underserved populations, due to new acquisition of Medicaid insurance by patients. Many FQHCs are employing non-invasive strategies, such as the fecal immunochemical test (FIT), to increase screening rates. Non-invasive tests such as the FIT are generally inexpensive, convenient, and often acceptable for patients. However, effectiveness of non-invasive screening in prevention or early detection of CRC depends heavily on ability to ensure diagnostic colonoscopy after abnormal screening tests. Specifically, prevention and early detection benefits of identifying patients through non-invasive screening at increased risk for CRC and polyps can only be realized if rates of diagnostic colonoscopy after positive tests are high. Indeed, up to 1 in 33 patients with an abnormal FIT have CRC. As part of a community-academic partnership between Family Health Centers of San Diego (FHCSD), San Diego State University, and UC San Diego Moores Cancer Center, we aimed to characterize CRC screening processes, including rates of complete diagnostic follow up after abnormal FIT testing.
Methods. FHCSD is a large FQHC serving 134,788 patients annually through 19 community clinics. The patient population is largely Latino (55%); 97% live at or below 200% of poverty, with most patients having less than a high school education. Following the Quality of Cancer Care Continuum principles adapted by Tiro et al.1 for CRC screening, we mapped the CRC screening process at FHCSD, and characterized drop-offs at various steps in the screening process by querying the electronic health record to identify all individuals with FIT orders over a six-month period (10/01/15 - 03/31/16). Outcomes of interest included rates of FIT completion, abnormal test results, and colonoscopy orders and completion among patients with an abnormal FIT, characterized via descriptive statistics.
Results. Over a six-month period, across 19 clinics within FHCSD, 9,378 FITs were ordered. Patients returned 25% of FITs ordered (2327/9378). Among returned FITs, 7% were abnormal (156/2327). Among patients with an abnormal FIT 85% (132/156) had orders for referral colonoscopy, and 21% had documented evidence of colonoscopy completion (33/156). FIT return was statistically significantly higher for patients without (33%; 368/1119) vs. with insurance (24%; 1959/8259; p comparison = <0.001). However, diagnostic colonoscopy completion after abnormal FIT was higher for patients with (24%; 31/132) vs. without insurance (8%; 2/24), though the difference was not statically significant.
Conclusions.Low rates of diagnostic colonoscopy after abnormal non-invasive CRC screening tests may adversely impact effectiveness of CRC screening programs. Research should focus on understanding reasons for fall offs in the screening process, and developing multilevel interventions to optimize follow up, particularly given the expanding array of non-invasive CRC screening tests being made available in usual practice. Conducting these studies in FQHC settings is critical, since increases in screening in these settings may largely occur as a result of implementation and promotion of non-invasive tests.

Abstract
BACKGROUND The SEUSA program, the Donation and Transplantation Institute foundation consultancy program, was implemented in Trinidad and Tobago (T&T) in 2010 with the support of the National Organ Transplant Unit (NOTU) and the Ministry of Health of T&T. METHODS The SEUSA program included (1) diagnosis of the current situation using the ODDS (Organ Donation Diagnostic Surveys); (2) creation of a human resources structure through Transplant Procurement Management (TPM); (3) detection of all brain and cardiac deaths in the hospitals implementing the DAS (Decease Alert System); (4) in-hospital awareness based on the EODS (Essentials in Organ Donation); and (5) external hospital audits. Additionally continued monitoring is performed. RESULTS Thus far, thanks to implementation of the SEUSA program in Trinidad and Tobago 175, healthcare professionals have been exposed to training programs in the organ donation field. The Living Kidney Program was reinforced and the structure of the Deceased Donation (DD) network was defined. Since 2010, 485 potential organ donors have been detected, and 9 have become actual organ donors; 74 patients have received a kidney transplant (59 from living and 15 from deceased donors). CONCLUSIONS This project results demonstrate that the application of the SEUSA program is an efficient methodology to develop DD programs that increase and consolidate transplant programs in the Caribbean region.

Abstract
Abstract
A novel line of research has emerged suggesting that daily feeding-fasting schedules have metabolic implications that are highly relevant to breast cancer. In rodents, a habitual daily fasting schedule that is aligned with sleep-wake cycles appears to have favorable effects on a variety of cancer risk factors and may reduce cell proliferation. While data from rodent models are compelling, no human studies have explored the potential impact of this type of fasting schedule on cancer risk factors such as hyperglycemia (a possible facilitator of neoplastic proliferation). We examined cross-sectional associations of nighttime fasting duration with glycemic control biomarkers associated with increased breast cancer risk in a population-based sample of women in the 2009-2010 U.S. National Health and Nutrition Examination Survey.
Dietary, anthropometric and glycosylated hemoglobin (HbA1c) data were available for 2,212 women, and 2-hour postprandial glucose concentrations were available for 1,066 women. Nighttime fasting duration was calculated using time-stamped 24-hour food records. Separate linear regression models examined associations of nighttime fasting with HbA1c and 2-hour glucose concentrations. Logistic regression modeled associations of nighttime fasting duration with elevated HbA1c (HbA1c ≥ 39 mmol/mol or 5.7%) and elevated 2-hour glucose (glucose ≥ 140 mg/dL). All models adjusted for age, education, race/ethnicity, BMI, total kcal intake, evening kcal intake, and the number of eating episodes per day. All analyses used sample weights to account for differential probabilities of selection into the sample, nonresponse, and noncoverage. Standard errors were estimated using Taylor Series Linearization.
Women in this sample were an average of 46.8 years of age (SE = 0.66) and fasted approximately 12.4 (SE = 0.08) hours per night. Each 3-hour increase in nighttime fasting (roughly one standard deviation) was associated with a 4% lower 2-hour postprandial glucose measurement (β 0.96, 95% CI 0.93 - 1.00; p<0.05), and a non-statistically significant 0.4 unit decrease in HbA1c (β -0.39, 95% CI -0.84 - -0.05; p = 0.08). Logistic regression models indicate that each 3-hour increase in nighttime fasting duration was associated with roughly a 20% reduced odds of elevated HbA1c (OR 0.81, 95% CI 0.68, 0.97; p<0.05) and non-significantly reduced odds of elevated 2-hour glucose (OR 0.78, 95%CI 0.53-1.54).
Randomized trials are needed to confirm whether a prolonged nighttime fasting schedule could improve biomarkers of glycemic control, thereby reducing breast cancer risk among women.

Abstract
BACKGROUND A novel line of research has emerged, suggesting that daily feeding-fasting schedules that are synchronized with sleep-wake cycles have metabolic implications that are highly relevant to breast cancer. We examined associations of nighttime fasting duration with biomarkers of breast cancer risk among women in the 2009-2010 U.S. National Health and Nutrition Examination Survey. METHODS Dietary, anthropometric, and HbA1c data were available for 2,212 women, and 2-hour postprandial glucose concentrations were available for 1,066 women. Nighttime fasting duration was calculated using 24-hour food records. Separate linear regression models examined associations of nighttime fasting with HbA1c and 2-hour glucose concentrations. Logistic regression modeled associations of nighttime fasting with elevated HbA1c (HbA1c ≥ 39 mmol/mol or 5.7%) and elevated 2-hour glucose (glucose ≥ 140 mg/dL). All models adjusted for age, education, race/ethnicity, body mass index, total kcal intake, evening kcal intake, and the number of eating episodes per day. RESULTS Each 3-hour increase in nighttime fasting (roughly 1 SD) was associated with a 4% lower 2-hour glucose measurement [β, 0.96; 95% confidence interval (CI), 0.93-1.00; P < 0.05], and a nonstatistically significant decrease in HbA1c. Logistic regression models indicate that each 3-hour increase in nighttime fasting duration was associated with roughly a 20% reduced odds of elevated HbA1c (OR, 0.81; 95% CI, 0.68-0.97; P < 0.05) and nonsignificantly reduced odds of elevated 2-hour glucose. CONCLUSIONS A longer nighttime duration was significantly associated with improved glycemic regulation. IMPACT Randomized trials are needed to confirm whether prolonged nighttime fasting could improve biomarkers of glucose control, thereby reducing breast cancer risk.

Abstract
Background Little is known about the feasibility and acceptability of tailored text message based weight loss programs for English and Spanish-language speakers. Objective This pilot study evaluated the feasibility, acceptability, and estimated impact of a tailored text message based weight loss program for English and Spanish-language speakers. The purpose of this pilot study was to inform the development of a full-scale randomized trial. Methods There were 20 overweight or obese participants (mean age 40.10, SD 8.05; 8/20, 40% male; 9/20, 45% Spanish-speakers) that were recruited in San Diego, California, from March to May 2011 and evaluated in a one-group pre/post clinical trial. For 8 weeks, participants received and responded to 3-5 text messages daily sent from a fully automated text messaging system. They also received printed weight loss materials and brief 10-15 minute weekly counseling calls. To estimate the impact of the program, the primary outcome was weight (kg) measured during face-to-face measurement visits by trained research staff. Pre and post differences in weight were analyzed with a one-way repeated measures analysis of variance. Differences by language preference at both time points were analyzed with t tests. Body mass index and weight management behaviors also were examined. Feasibility and acceptability were determined by recruitment success, adherence (ie, percentage of replies to interactive text messages and attrition), and participant satisfaction. Results Participants who completed the final assessment (N=18) decreased body weight by 1.85 kg (F1,17=10.80, P=.004, CI∆ 0.66-3.03, η2=0.39). At both time points, there were no differences in weight by language preference. Participants responded to 88.04% (986/1120) of interactive text messages, attrition rate was 10% (2/20), and 94% (19/20) of participants reported satisfaction with the program. Conclusions This fully automated text message based weight program was feasible with English and Spanish-speakers and may have promoted modest weight loss over an 8-week period.

Abstract
PURPOSE This article describes the conceptual model developed for the Hispanic Community Health Study/Study of Latino Youth, a multisite epidemiologic study of obesity and cardiometabolic risk among U.S. Hispanic/Latino children. METHODS Public health, psychology, and sociology research were examined for relevant theories and paradigms. This research, in turn, led us to consider several study design features to best represent both risk and protective factors from multiple levels of influence, as well as the identification of culturally relevant scales to capture identified constructs. RESULTS The Socio-Ecological Framework, Social Cognitive Theory, family systems theory, and acculturation research informed the specification of our conceptual model. Data are being collected from both children and parents in the household to examine the bidirectional influence of children and their parents, including the potential contribution of intergenerational differences in acculturation as a risk factor. Children and parents are reporting on individual, interpersonal, and perceived organizational and community influences on children's risk for obesity consistent with Socio-Ecological Framework. CONCLUSIONS Much research has been conducted on obesity, yet conceptual models examining risk and protective factors lack specificity in several areas. Study of Latino Youth is designed to fill a gap in this research and inform future efforts.

Abstract
PURPOSE This article describes the design and methodology of the Study of Latino Youth (SOL Youth) study, a multicenter study of Hispanic/Latino children living in the United States. METHODS Participants are children aged 8-16 years whose parents/legal guardians participated in the Hispanic Community Health Study/Study of Latinos, a large community-based cohort study of Hispanic/Latino adults living in the United States. RESULTS Between 2012 and 2014, 1600 children recruited from four field centers (Bronx, Chicago, Miami, and San Diego) will undergo a 3.5-hour examination to collect biospecimens, obtain anthropometric measures, blood pressure, fitness level, dietary intake, and physical activity. Psychosocial and environmental characteristics are assessed by questionnaire. Primary study aims are to examine associations of youth's lifestyle behaviors and cardiometabolic risk factors with (1) youth's acculturation and parent-child differences in acculturation; (2) parenting strategies, family behaviors, and parental health behaviors; and (3) youth's psychosocial functioning. CONCLUSIONS SOL Youth will determine the prevalence and distribution of obesity-promoting lifestyle behaviors, cardiometabolic risk profiles, and novel biomarkers associated with obesity and insulin resistance. This article describes the study methodology and considers advantages and limitations of embedding a cohort of children within a well-characterized cohort of adults.

Abstract
Access to physical activity opportunities are limited in underserved communities. Community-based programs can increase promotoras and youth leaders’ capacity to advocate for built environmental changes. Promotoras and youth leaders were trained on walkability assessment, park audits, and advocacy. The youth and promotoras from one church located adjacent to a park implemented a community survey, conducted walk audits, and engaged in consciousness-raising activities about environmental factors that affect communities. They also mobilized community members to advocate for a nearby park. Advocacy tactics included attending and making presentations at the City Council, planning meetings, organizing health fairs, and speaking to community members. The following changes were made at the park: removed overgrown plants, relocated storage container, increased park security (i.e., lighting, fencing), improved safety (i.e., covered sewer drain, sand lot removed), enhanced amenities (i.e., drinking fountain, bathroom, benches, tables), improved pedestrian safety in park (i.e., leveled the old and added new walking paths), and improved children’s play area (i.e., new play equipment, fencing). The current program highlights factors that contributed to park changes and challenges in increasing access to parks. Furthermore, the current study notes steps that other programs can take to make environmental changes.

Evaluation of adipocytic changes after a simil-lipocryolysis stimulus. CRYO LETTERS 2013; 34:100-105. [PMID: 23435706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/01/2023]
Abstract
Lipocryolysis is considered as an effective, well-tolerated non-invasive procedure to reduce local adiposities. However there is little information about its mechanism of action by the procedure. It is proposed that lipid phase transition or crystallization may be an unleashed apoptotic stimulus. Yet, the post-lipocryolysis apoptosis is not easily confirmed, least of all is its correlation with crystallization. In this study adipocytes from rat fat tissue were exposed to a lipocryolysis-session-like stimulus. Lipid changes were observed in all test sample.

Abstract
OBJECTIVE This intervention sought to promote healthy eating with the ultimate goal of reducing childhood obesity risk. MATERIALS AND METHODS Three hundred and sixty-one Latino families living on the US-Mexico border with at least one child between 7-13 years of age were eligible to participate. Families randomly assigned to the four-month intervention received 14 contacts with a promotora (community health worker), consisting of 11 home visits and three telephone calls; the control condition was a delayed treatment intervention. Children reported on their dietary intake at baseline, immediately post-intervention and at the six month follow-up visit. RESULTS The intervention reduced weekly consumption of fast food (p<0.05). A dose-response relationship was observed such that for every seven hours of promotora contact, monthly variety of fruits (p<0.01) and vegetables (p<0.01) increased by one. No other intervention effects were observed. CONCLUSIONS Family-based interventions can improve children's eating habits, with the amount of contact with the promotora being key to success.

Abstract
BACKGROUND Parenting interventions have achieved changes in factors associated with childhood obesity but few have tested the effects on multiple parental influences. PURPOSE This study examined the efficacy of an intervention aimed at improving several dimensions of parenting related to childhood obesity. DESIGN The study used a 2 x 2 factorial design. SETTING/PARTICIPANTS In 2003, a sample of 13 Southern California schools was randomized to one of four conditions: micro-environment only, macro-environment only, micro-plus-macro-environment, and no treatment control condition. Participants included 811 predominantly Mexican immigrant/Mexican-American mothers with children in kindergarten through second grade. INTERVENTION In both micro conditions, participants received monthly home visits by a promotora over a 7-month period plus monthly mailed newsletters. MAIN OUTCOME MEASURES In 2008, intervention effects were examined on (1) parenting strategies, including limit setting, monitoring, discipline, control, and reinforcement related to children's diet and physical activity; (2) parental support for physical activity; (3) parent-mediated family behaviors such as family meals eaten together and TV watching during family dinners; and (4) perceived barriers and other parent cognitions related to children's eating and activity. RESULTS At the 2-year follow-up, significant improvements were observed in three of five parenting strategies, parental support, and two of four parent-mediated family behaviors among parents receiving the micro intervention (i.e., those who received promotora visits and monthly newsletters), as compared with those in the macro-only and control conditions. CONCLUSIONS Aspects of parenting related to children's risk for obesity and related health outcomes are modifiable with the support of a promotora and print media.

Abstract
PURPOSE This study was designed to examine the associations of physical activity and body composition with cardiorespiratory fitness in eighth grade girls. METHODS A random sample of 1440 eighth grade girls at 36 schools participated in this cross-sectional investigation, which represented an ethnically and geographically diverse group. Cardiorespiratory fitness was assessed using a modified physical work capacity test on a cycle ergometer that predicted workload at a heart rate of 170 beats.min. Physical activity was assessed over 6 d in each girl using an accelerometer and body composition was estimated from body mass index and triceps skinfolds using a previously validated equation. Pearson correlations and multiple regression analyses were used to determine the relationships among fitness, physical activity, and body composition. RESULTS Significant linear relationships among cardiorespiratory fitness, body composition, and physical activity were found. The combination of fat and fat-free mass along with racial group and a race by fat-free-mass interaction accounted for 18% (R) of the variation in physical fitness. Adding moderate-to-vigorous physical activity to the regression model increased the R to 22%. Black girls had somewhat lower fitness levels (P < 0.05) especially at higher levels of fat and fat-free mass than other racial/ethnic groups. CONCLUSIONS Physical activity, fat-free mass, and the interaction between fat-free mass and racial group are significantly associated with cardiorespiratory fitness in adolescent girls.
