RESUMEN

OBJECTIVES: The purpose of this study was to investigate the effects of 6 weeks of resistance training (RT) combined with aerobic training (AT) and Tirzepatide supplementation on lipid profiles, insulin resistance, anthropometric characteristics and physical fitness in prediabetic obese soldiers. METHODS: 61 obese men were randomly divided into six groups: Placebo; Tirzepatide 5 mg (T5); Tirzepatide 2.5 mg (T2.5); Hypertrophy, Strength, Power-Circuit Training+Placebo (Ex+P); Hypertrophy, Strength, Power-Circuit Training+Tirzepatide 5 mg (Ex+T5); Hypertrophy, Strength, Power-Circuit Training+Tirzepatide 2.5 mg (Ex+T2.5). All training groups performed aerobic training (AT) after resistance training. Subjects trained for six weeks, three sessions per week. Before and after the intervention period, the participants were evaluated for anthropometric measures, body composition [body weight, body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR) and fat mass (FM)], cardiorespiratory fitness (VO2max), and muscle strength (chest press 1RM and leg press 1RM). Blood biochemistry evaluations included triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), insulin level and insulin resistance (HOMA-IR). To evaluate the differences between the groups, ANCOVA statistical method was used along with Bonferroni's post hoc test, and the significance level was P <  0.05. RESULTS: Body weight, BMI, WC, FM, FBG, LDL-C, TC, TG and HOMA-IR were significantly decreased in Ex+P, Ex+T5 and Ex+T2.5 groups compared to Placebo, T5 and T2.5 groups. WHR significantly decreased in Ex+P, Ex+T5 and Ex+T2.5 groups compared to Placebo group. HDL-C, chest press and leg press significantly increased in Ex+P, Ex+T5 and Ex+T2.5 groups compared to Placebo, T5 and T2.5 groups. VO2max significantly increased and insulin significantly decreased in Ex+P group compared to Placebo, T5 and T2.5 groups. FM, FBG and TG were significantly decreased in both the T2.5 and T5 groups compared to Placebo group. HOMA-IR, LDL-C and TC significantly decreased in the T5 group compared to Placebo group. Also, leg press significantly increased in Ex+P group compared to all other groups. CONCLUSIONS: Performing six weeks of combined resistance and aerobic training in the form of RT+AT alone is more effective than the simultaneous use of Tirzepatide on cardiorespiratory fitness, strength, and modulating insulin levels. Taking Tirzepatide in doses of 5 mg and 2.5 mg in combination with exercise training did not have a significant advantage over exercise training alone. Finally, taking Tirzepatide in doses of 5 mg or 2.5 mg in combination with exercise training is not significantly superior to each other.

RESUMEN

INTRODUCTION: The aim of this study was to investigate 12 wk of simple and complex voluntary wheel running on Alzheimer's disease (AD), associated biomarkers, and behaviors. METHODS: Sixty male Wistar rats were randomly divided into six groups: healthy control (Con-Sed), AD only (AD-Sed), simple wheel control (SWC), complex wheel control (CWC), simple wheel AD (SWAD), and complex wheel AD (CWAD). Novelty-suppressed feeding test and the Morris water maze test were used to evaluate depression and memory, respectively. Ki67 was measured in the hippocampus, whereas interleukin (IL)-1ß and neural/glial antigen 2 (NG2) were measured in both the hippocampus and the prefrontal cortex. One-way ANOVA with Tukey's post hoc test was performed. RESULTS: AD-Sed group had significantly lower spacial memory ( P < 0.001) compared with Con-Sed. Simple and complex wheel running attenuated these deficits in the SWAD and CWAD groups, respectively ( P < 0.001). Only the CWAD group had significantly improved novelty-suppressed feeding test time compared with AD-Sed ( P < 0.001), equivalent to the healthy wheel running groups. AD-Sed has significantly higher hippocampal concentrations of Ki67 ( P = 0.01) compared with the Con-Sed. Both SWAD and CWAD had significantly reduced Ki67 with similar concentrations compared with the SWC and CWC groups ( P > 0.05). AD-Sed animals also presented with significantly higher hippocampal and prefrontal cortex concentrations of IL-1ß compared with Con-Sed ( P < 0.001). SWAD and CWAD had no effect in changing these concentrations. Complex wheel running significantly increased NG2 in the healthy control and AD models, whereas simple wheel running significantly increased NG2 in the AD model. CONCLUSIONS: The results of our study suggest that complex wheel running might be more advantageous in promoting memory and neuroplasticity while reducing depression that is associated with AD.

RESUMEN

Multiple sclerosis (MS) is associated with an impaired immune system that severely affects the spinal cord and brain, and which is marked by progressive inflammatory demyelination. Patients with MS may benefit from exercise training as a suggested course of treatment. The most commonly used animal models of studies on MS are experimental autoimmune/allergic encephalomyelitis (EAE) models. The present review intends to concisely discuss the interventions using EAE models to understand the effectiveness of exercise as treatment for MS patients and thereby provide clear perspective for future research and MS management. For the present literature review, relevant published articles on EAE animal models that reported the impacts of exercise on MS, were extracted from various databases. Existing literature support the concept that an exercise regimen can reduce the severity of some of the clinical manifestations of EAE, including neurological signs, motor function, pain, and cognitive deficits. Further results demonstrate the mechanisms of EAE suppression with information relating to the immune system, demyelination, regeneration, and exercise in EAE. The role for neurotrophic factors has also been investigated. Analyzing the existing reports, this literature review infers that EAE is a suitable animal model that can help researchers develop further understanding and treatments for MS. Besides, findings from previous animal studies supports the contention that exercise assists in ameliorating MS progression.

RESUMEN

INTRODUCTION: Chronic inflammation can remain many years after the completion of cancer treatment and is associated with cancer recurrence. The purpose of this study was to examine how a 16-week therapeutic yoga program (TYP) modulates the cytokine profile in heterogeneous cancer survivors. METHODS: Eligible participants were 18 years of age or older and clinically diagnosed with cancer. Consenting participants were asked to attend three, 75-min sessions weekly of TYP with meditation. Seventeen patients provided blood samples at baseline and end of study. Eight cytokines (interferon (IFN)-γ; interleukin (IL)-1b, IL-1ra, IL-4, IL-6, IL-8, IL-10; and tumor necrosis factor (TNF)-α), three receptors (sIL-6R, sTNFRI, sTNFRII), and C-reactive protein (CRP) were quantified. RESULTS: Patients were 59.6 ± 7.3 years old; over half (56%) were overweight or obese BMI ≥ 25 kg/m2); majority were female (71%) and breast cancer survivors (65%), of which 44% were Hispanic. Marked reductions were observed in all cytokines except IL-4, with significant reductions (p < 0.05) found in IL-1b (- 13%) and IL-1ra (- 13%). No significant changes were observed in soluble cytokine receptors or CRP. CONCLUSIONS: TYP led to significant reduction in circulating cytokines associated with chronic inflammation in a heterogeneous sample of cancer survivors.

RESUMEN

OBJECTIVES: This study aimed to demonstrate potential translation of pre-clinical studies to a home-based exercise intervention in mediating inflammatory cytokine markers and tumor progression in men under active surveillance for prostate cancer. METHODS: A 2-arm randomized control parallel group design was used. The exercise intervention consisted of 24 weeks of an aerobic and resistance home-based exercise program and results were compared to a waitlist control group. Data were collected at baseline and end of study for eotaxin, interferon-γ (INF-γ), interleukin-12 (IL-12), interleukin-1α (IL-1α), interleukin-5 (IL-5), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and vascular endothelial growth factor (VEGF), distanced walked during a 6-minute walk test (6MWT), body mass index, and health-related quality of life. RESULTS: Non-significant decreases were observed in all biomarkers, especially VEGF (pre: 125.16 ± 198.66, post: 80.29 ± 124.30, P = .06) and INF-γ (pre: 152.88 ± 312.71, post: 118.93 ± 158.79, P = .08), in the intervention group; only IL- α (pre: 332.15 ± 656.77, post: 255.12 ± 502.09, P = .20) decreased in the control group while all other biomarkers increased from baseline to end of study. A non-significant increase in 6MWT distance was observed in the intervention group, while a decrease was seen in the control group. Significant decreases in physical function, emotional wellbeing, and total composite scale on the FACIT-F were observed in the intervention group, possibly due to the isolation restrictions of COVID-19. Physical function on the SF-36 significantly increased in the control group. CONCLUSIONS: Future studies with powered samples are needed to confirm the trends observed for inflammatory biomarkers and functional fitness.

RESUMEN

BACKGROUND: Skepticism among the public surrounding the COVID-19 vaccine is still prevalent despite vaccine-positive communication and many Americans having already received the vaccine. Side effects of the vaccine, as well as its expeditious research and development, are among the top concerns among those hesitant to receive the coronavirus vaccine. Moreover, there is additional concern regarding the association between comorbidities and severity of illness due to the coronavirus pandemic. OBJECTIVE: We aimed to describe the pandemic- and vaccine-related concerns of South Texas residents who attended the UT Health San Antonio School of Nursing's vaccine clinic with the goal of better understanding vaccine-related misconceptions and hesitancy for subsequent vaccination campaigns and boosters. METHODS: An electronic survey accessible via a QR code on printed flyers was distributed throughout the waiting areas and post-vaccine observation rooms within the COVID-19 vaccine clinic at UT Health San Antonio School of Nursing from April 5 to 16, 2021. The survey contained a primary open-ended question designed to obtain information on concerns of the clinic attendees regarding the COVID-19 pandemic and COVID-19 vaccine. A thematic analysis was performed on the qualitative data to identify major themes to better understand concerns of vaccine clinic visitors. RESULTS: During the 11-day period, 510 attendees received vaccinations through the vaccination clinic and completed the survey. Five areas of concern were identified by the 277 attendees: immunity, future vaccinations, vaccine symptoms and safety, protocol post-vaccination, and child vaccinations. Post-hoc sentiment analysis showed that responses were generally neutral or negative. CONCLUSION: This study provides a perspective regarding questions and concerns of South Texas residents regarding the COVID-19 pandemic, the vaccine, and their general health status within a vaccinated population. Vaccine recipients were found to still have questions even after receiving the vaccine, suggesting that eliminating uncertainty surrounding the COVID-19 vaccine is not necessary to motivate individuals to receive the vaccine. Instead, addressing concerns through public health messaging could be a useful strategy to address vaccine-related concerns and increase subsequent vaccine uptake in future vaccination campaigns and boosters.

RESUMEN

BACKGROUND: In breast cancer survivors, chemotherapy-induced muscle loss has been shown to be attenuated with structured resistance exercise. Creatine supplementation can increase bioenergetics in skeletal muscle, which helps to improve overall strength and endurance and reduce muscular fatigue. Therefore, we hypothesize that adding creatinine supplementation to exercise training will accelerate improvements in strength, endurance, and bioenergetics in breast cancer survivors. OBJECTIVE: The primary objective is to determine the effects of combining creatine supplementation with exercise on modulating strength and physical function in breast cancer survivors by comparing these effects to those of exercise alone. The secondary objectives are to determine if creatine supplementation and exercise can increase the intramuscular storage of creatine and improve body composition by comparing this intervention to exercise alone. METHODS: We aim to test our hypothesis by conducting an open-label randomized controlled trial of 30 breast cancer survivors who have completed chemotherapy within 6 months of enrollment. Eligible participants will be equally randomized (1:1) to either a creatine and exercise group or an exercise-only group for this 12-week intervention. Individuals who are randomized to receive creatine will be initially dosed at 20 g per day for 7 days to boost the availability of creatine systemically. Thereafter, the dose will be reduced to 5 g per day for maintenance throughout the duration of the 12-week protocol. All participants will engage in 3 center-based exercise sessions, which will involve completing 3 sets of 8 to 12 repetitions on chest press, leg press, seated row, shoulder press, leg extension, and leg curl machines. The primary outcomes will include changes in strength, body composition, and physical function in breast cancer survivors. The secondary outcomes will be intramuscular concentrations of creatine and adenosine triphosphate in the vastus lateralis, midthigh cross-sectional area, and quality of life. RESULTS: As of October 2021, a total of 9 patients have been enrolled into the study. No unexpected adverse events have been reported. CONCLUSIONS: Creatine is being studied as a potential agent for improving strength, endurance, and bioenergetics in breast cancer survivors following chemotherapy. The findings from our trial may have future implications for supporting breast cancer survivors in reversing the muscle loss experienced during chemotherapy and improving their physical function and quality of life.

RESUMEN

The genetic factors involved with salt sensitivity (SS) have been studied using a genetic approach to identify individuals at high risk for developing hypertension and could benefit from a low sodium diet intervention, but this has not been well-studied in Korean American immigrants (KAIs). The purpose of this pilot study was to investigate the influence of SS that moderates blood pressure (BP) in KAIs (n = 34). KAIs were recruited from local communities and completed a blood draw, a 8-day food log, and BP testing. The dietary sodium intake was measured using the Fitbit mobile app, and an SS biomarker was assessed using targeted genotyping. out of five GNAI2 single nucleotide polymorphisms (SNPs) tested, rs4547694 significantly moderated the relationship of dietary sodium intake on BP in KAIs. Conclusions: Further studies are warranted to test the effect of a reduced sodium diet on BP while accounting for the moderating influence of an SS genotype.

RESUMEN

BACKGROUND: COVID-19 was declared a pandemic by the World Health Organization on March 11, 2020, and as of this writing, Texas, United States, has reported >675,000 cases with over 14,000 deaths. Many of the preventive measures implemented during the pandemic can increase sedentary lifestyles, which can lead to the development of chronic diseases, including obesity, among the general population and cause serious threats to people's physical health and overall quality of life. Individuals with pre-existing comorbidities are at an increased risk of COVID-19 and may hence have higher levels of stress. OBJECTIVE: This study aimed to investigate the relationship between physical activity levels and mental health status on an individual level and to compare them between those with and those without comorbidities in a cohort of Texas residents, before and after COVID-19 was declared a pandemic. METHODS: An electronic survey was disseminated throughout various regions of Texas. In total, 160 individuals were asked questions about their demographic characteristics, time spent on daily physical activities, and daily mental health status before and after COVID-19 was declared a pandemic. Frequency distributions and descriptive statistics were analyzed. RESULTS: Overall, 94 (58%) participants reported having ≥1 medical condition, and 31 (13.1%) had >3 medical conditions. Physical activity levels among participants with ≥1 pre-existing comorbidity drastically-but not significantly-decreased, as evident from a 10% increase in sedentary lifestyles after COVID-19 was declared a pandemic. On the contrary, we observed a 9% increase in the number of individuals without a pre-existing comorbidity who reported 30-60 min of physical activity per week. There was a 2-fold increase in the number of participants reporting more frequent feelings of nervousness, too much worry, trouble relaxing, and the fear of something awful happening after the pandemic. More specifically, individuals with pre-existing medical conditions reported, on average, a 10% higher incidence of feelings of stress, anxiety, and sadness compared to their healthy counterparts after COVID-19 was declared a pandemic. CONCLUSIONS: Stressful life conditions and chronic comorbidities are risk factors that can affect mental health and reduce the ability to perform activities of daily life. Therefore, when implementing pandemic protocols, municipalities should consider providing mental health support to their citizens to protect them from this rather inconspicuous adverse effect.

RESUMEN

BACKGROUND: Herein, we propose a novel RCT study to collect preliminary data on the impact of a 24-week home-based exercise program that can improve prognosis, physical function, and quality of life (QoL) in men with prostate cancer (PCa). This study will provide data on the feasibility of conducting a home-based exercise study and pilot data on the impact of exercise on circulating concentrations of biomarkers reported in the literature to be beneficial for the prognostication of PCa. METHODS/DESIGN: Thirty male patients, clinically-diagnosed with prostate cancer under active surveillance, will be recruited to participate in a 2-arm, 24-week home-based program. Random allocation to each arm - intervention, and control - will be performed in a 1:1 ratio. Participants assigned to the intervention group will perform 30 min of light-to-moderate intensity walking five days a week (40-60% heart rate reserve) and three sets of 15 repetitions of light callisthenic exercises (bodyweight squats, incline push-ups, and hip thrusts) 3 days a week. Participants randomized to the control group will maintain normal activity throughout the 24 weeks. Four visits occurring at baseline, 12-, 18-, and 24-weeks will be used to assess QoL, body composition, prognostic biomarker concentrations, and overall physical function. Primary endpoints include significant changes in prognostic biomarkers. Secondary endpoints include changes in quality of life, physical function and body composition. DISCUSSION: This study should demonstrate preliminary evidence that a home-based exercise intervention can impact biomarkers of progression while improving quality of life, physical function and body composition. Results from this study have the potential to promote health and wellness while minimizing cancer progression in men with PCa.

RESUMEN

The purpose of this investigation was to compare the antitumorigenic effects of the natural product Nexrutine to voluntary wheel running (VWR) in the transgenic adenocarcinoma of the mouse prostate (TRAMP) model. Forty-five, 10-week old TRAMP mice were randomized to either receive free access to the running wheel, Nexrutine pelleted into chow at 600 mg/kg or no treatment control. Mice were serially sacrificed at weeks 4, 8,12 and 20 weeks. Palpable tumors, body weight, food consumption and running wheel activity were monitored weekly. At necropsy, tumors and serum were harvested and stored for analysis. Serum was used to quantify circulating cytokines in 4 and 20 week time points. Nexrutine supplementation led to a 66% protection against high grade tumors. Exercise resulted in a 60% protection against high grade tumors. Both interventions reduced concentrations of IL-1α. Exercise also significantly lowered concentrations of eotaxin, IL-5, IL-12(p40) and VEGF. While there were no significant differences at baseline, exercise mice had significantly lower IL-5 and VEGF compared to control at the 20 week time point. Nexrutine also significantly reduced circulating IL-9 concentrations. No significant differences were observed when compared to the control group. Immunohistochemistry of tumor sections showed significantly lower expression of pAkt in Nexrutine fed mice with no visible differences for NFκB. In conclusion, both Nexrutine and exercise suppressed tumor growth. Though similar outcomes were seen in this comparative effectiveness study, the mechanisms by which exercise and Nexrutine exert this benefit may focus on different pathways.

RESUMEN

Muscle loss is a debilitating side effect to prostate cancer (PCa) experienced by nearly 60% of men. The purpose of this study was to test the hypothesis that Nexrutine® , a bark extract from the Phellodendrum amurense, can protect against prostate cancer induced muscle loss in a similar manner as exercise, using the transgenic adenocarcinoma of mouse prostate (TRAMP) model. Forty-five, 8- to 10-week old TRAMP mice were randomized to either control, Nexrutine® (600 mg/kg pelleted in chow) or exercise (voluntary wheel running). Mice were serially sacrificed at weeks 4, 8, 12, and 20, at which time either the left or right gastrocnemius muscle was harvested, weighted, and frozen. Proteolysis inducing factor (PIF), ubiquitin, and NF-κB concentrations were quantified using ELISA kits. Nexrutine® and exercise were equally able to protect TRAMP mice against PCa-induced muscle loss (P = 0.04). Both interventions decreased intramuscular PIF concentrations at 20 weeks compared to control (P < 0.05). A treatment effect was also observed when all time points were combined with exercise significantly lowering PIF concentrations (P < 0.01). Exercise significantly lowered intramuscular ubiquitin concentrations in weeks 4, 8, and 20 compared to control mice (P < 0.001). A treatment effect was also observed with exercise significantly lowering ubiquitin compared to control mice (P < 0.001). No significant changes were observed for NF-κB. The results of this investigation demonstrate that PCa-induced muscle loss can be attenuated with the herbal supplement Nexrutine® . This investigation provides preliminary evidence to support continued research into Nexrutine® as a potential exercise analog in protecting against muscle loss.

RESUMEN

AIMS: Parkinson's disease (PD) is characterized by progressive loss of dopamine cells. It is suggested that exercise could be employed as a non-pharmacological approach for reducing the risk of PD incidence. The purpose of this study was to compare the effects of 4-week Mild-intensity (MIEx) and progressive exercise (PEx) protocols on rotational behavior, GFAP, DA, TH, MANF, CDNF and NGF levels in striatum of parkinsonian rats induced by 6-hydroxydopamine. METHODS: 42 Wistar male rats were divided into 6 groups including, healthy and PD controls, MIEx, PEx, healthy MIEx, and healthy PEx. MIEx protocol was performed as follows: 5 days a week, 2 sessions a day of 15 min at a speed of 15 m/min. PEx protocol encompassed a training regimen of 5 days a week initiating by 20 min in the first day reaching 50 min on the fifth day and 60 min in the next 3 weeks. PD was induced after training protocol by injection of 6-OHDA into the striatum of rats. For confirming PD, apomorphine rotational test was employed. KEY FINDINGS: The MIEx protocol did not have any positive impacts on the variables except for CDNF (P < 0.0001). Levels of DA (P < 0.0001) and TH (P = 0.0004) increased significantly after performing PEx protocol. Moreover, PEx protocol considerably reduced rotational behavior of rats (P = 0.0244). SIGNIFICANCE: The findings of this research confirm positive effects of PEx in protecting against PD. This progressive training protocol has explicitly shown a neuroprotective effect against PD-inducing nervous toxin through increasing neurotrophins.

RESUMEN

The purpose of this study was to examine the effects of exercise in modulating biomarkers of sarcopenia in a treatment naïve transgenic adenocardinoma of the mouse prostate (TRAMP) model. Thirty TRAMP mice were randomized to either exercise (voluntary wheel running) or no-treatment control group for a period of 20 weeks. During necropsy, gastrocnemius muscles and prostate tumors were harvested and weighed. Gastrocnemius concentrations of myostatin, insulin-like growth factor (IGF)-1 and tumor necrosis factor (TNF)-α were quantified. Exercise mice had greater muscle mass than controls (p=0.04). Myostatin was significantly lower in the exercise group compared to controls (p=0.01). Exercise mice maintained forelimb grip force while control mice had a significaint decrease (p=0.01). No significant difference was observed in pre-post all limb grip strength. Further, forelimb and all limb grip strength was negatively associated with tumor mass (p<0.01).

RESUMEN

Community and public health nurse researchers encompass a unique cohort of nurse researchers that have the skills and capacity to lead projects and programs of science centered on improvement of patient outcomes through methods of comparative effectiveness research (CER). CER, as a general method, has been taught to all nurses in the form of the PICO question to improve evidence-based practices. As the climate for funding becomes more and more competitive, nurse researchers are primed to lead the change in improving patient outcomes through patient centered outcomes research (PCOR). However, the number of projects funded by agencies like the Patient Centered Outcomes Research Institute, fall well below the capabilities of the field. The purpose of this commentary is to promote the field of PCOR and encourage novice and experienced nurse researchers to apply for funding from the PCORI by introducing different methods for building capacity and promoting engagement in the national conversations of PCOR and CER.

RESUMEN

BACKGROUND: There are currently 15 million Americans who provide over 80% of the care required by their family members with Alzheimer's disease and other dementias. Yet care for caregivers continues to be fragmented and few evidence-based interventions have been translated into routine clinical care and therefore remain inaccessible to most family caregivers. To address this gap, the Caring for the Caregiver program is being developed at UT Health San Antonio, School of Nursing to improve support services and health outcomes for family caregivers. Our purpose is to describe the engagement process undertaken to assess caregiver and community needs and how findings are informing program development. METHODS: We are using a model of public engagement that consists of communication of information, collection of information from stakeholders, and collaboration where stakeholders are partners in an exchange of information to guide program activities. An assessment of the community was undertaken to identify resources/services for family caregivers. Subsequently, stakeholders were invited to a community-academic forum to discuss strategies to build on existing strengths for family caregiving and to identify gaps in care. Detailed notes were taken and all discussions were recorded and transcribed for analysis. Data were analyzed using thematic content analysis. RESULTS: We conducted site visits with 15 community agencies, interviewed 13 family caregivers, and attended community events including support groups and health and senior fairs. Fifty-three diverse stakeholders attended the community-academic forum. Participants identified existing assets within our community to support family caregivers. Consistent among groups was the need to increase awareness in our community about family caregivers. Themes identified from the discussion were: making the invisible visible, you don't know what you don't know, learning too late, and anticipating and preparing for the future. CONCLUSIONS: Incorporating caregiver and community stakeholders was critical to ensure that the priorities of our community are addressed in a culturally responsive accessible program for family caregivers. The forum served as important mechanism to partner with the community and will be an annual event where we can continue to work with our stakeholders around needs for practice, education, and research.

RESUMEN

BACKGROUND: South Asians (SAs) have a well-documented risk for mortality related to coronary artery disease (CAD). However, there is a lack of evidence to guide the implementation and dissemination of primary and secondary interventions to control and deter progression of CAD in SAs. OBJECTIVE: The aim of this study is to explore and describe self-regulation behaviors in SAs with CAD using Leventhal's Common Sense Model. METHODS: In this mixed-methods study, quantitative data were collected using 3 survey questionnaires (demographics, Illness Perception Questionnaire-Revised, and Coping/Self-Regulation Behaviors). Before completing the surveys, a subset of the sample (n = 20) participated in individual face-to-face or telephone interviews. RESULTS: A total of 102 SAs were enrolled (age, 53.5 ± 9.98 years). On average, participants rated themselves high (63 ± 3.06) on negative perceptions. In addition, they discussed desi diet, stress, a lack of physical activity, ignoring symptoms, and kismet (fate) as the most important perceived causes of their CAD. Most of the participants modified their lifestyle after their CAD event. Participants expressed regret for not having changed their lifestyle earlier when they were experiencing early symptoms of their CAD. CONCLUSION: Findings from this study enhance the understanding of self-regulation behaviors of SAs with CAD. Ultimately, these findings will inform the development and implementation of targeted interventions that address culture-specific lifestyle modification for SAs with CAD.

RESUMEN

OBJECTIVE: To describe the effectiveness of engaging patient partners as "citizen scientists" in the research process to boost patient centered outcomes research in underrepresented populations. METHODS: Translational Advisory Boards in South Texas have effectively collaborated with University researchers to develop community-based patient centered research. Here we describe innovative approaches in research to engage patients and offer practical methods to enhance partnerships between patients and researchers to facilitate patient engagement. RESULTS: Three health issues identified by the TABs were diabetes, obesity and teen pregnancy Examples of other community inspired research topics include air and water quality, methicillin-resistant staphylococcus aureus, intimate partner violence, chronic pain, and human papilloma virus and hepatitis C vaccinations. CONCLUSION: Patient engagement of underrepresented populations is inverse to the vast disparities they experience. In order to adequately address our nation's deficits in providing equitable healthcare, we must fully integrate disparate partners into the research process. By engaging community champions, academic health centers can fully integrate meaningful interventions on topics of interest to the catchment area in which they serve. PRACTICE IMPLICATIONS: These lessons can be used in developing local and regional collaborations across the country to boost active participation of patient stakeholder in PCOR to reduce healthcare disparities and improve our healthcare systems.

RESUMEN

The purpose of this paper is to report the variance in institutional review board (IRB) reviews as part of the implementation of a multisite, quality improvement study through the Improvement Science Research Network (ISRN) and recommend strategies successful in procuring timely IRB approval. Using correspondence documents as data sources, the level of review was identified and time to submission, time to approval, and time to study start were analyzed. Thirteen of the 14 IRBs conducted independent reviews of the project. Twelve IRBs approved the study through expedited review while two IRBs reviewed the project at a full board meeting. Lastly, 11 of the 14 sites required documented consent. The greatest delay in approval was seen early on in the IRB process with site PIs averaging 45.1 ± 31.8 days to submit the study to the IRB. IRB approvals were relatively quick with an average of 14 ± 5.7 days to approval. The delay in study submission may be attributed to a lack of clear definitions and differing interpretations of the regulations that challenge researchers.
