RESUMO

Patients with solid tumor brain metastases that progress after whole-brain radiation have limited options. This prospective trial investigated the efficacy, safety, and tolerability of bevacizumab as salvage therapy in this population. Eligible patients received bevacizumab 10 mg/kg intravenously every 2 weeks until progression. The primary endpoint was radiologic response using Response Assessment in Neuro-Oncology (RANO) criteria. The secondary endpoints were progression-free survival (PFS), overall survival (OS), duration of response, and safety. Quality of life (QOL) was studied using the Functional Assessment of Cancer Therapy-Brain (FACT-Br) scale. Twenty-seven patients were enrolled, with twenty-four having evaluable data for response. The majority of histologies (n = 21, 78%) were breast cancer. The remaining histologies were non-small-cell lung cancer (n = 4, 15%), neuroendocrine cancer (n = 1, 3%), and papillary fallopian serous adenocarcinoma (n = 1, 3%). Eighteen patients had radiologic response, with two patients demonstrating partial response (8.33%) and sixteen patients demonstrating stable disease (66.7%). The median duration of response was 203 days. PFS at 6 months was 46%, median PFS was 5.3 m, and median OS was 9.5 m. Treatment was well tolerated, with six patients experiencing grade 3 lymphopenia and hypertension. There was one grade 3 thromboembolism. QOL was not negatively impacted. Bevacizumab is a safe and feasible salvage treatment with durable response and favorable overall survival for patients with progressive brain metastases after whole-brain radiation.

RESUMO

Engaging in multiple health risk behaviors simultaneously may increase the risk for cardiometabolic diseases. This study examined the prevalence and clustering of three health behaviors (physical activity, fruit and vegetable consumption, and smoking) among Latino men. The participants were 99 Mexican and 104 Puerto Rican men who participated in a study addressing culture- and obesity-related factors. The health behaviors were obtained from self-reported and anthropometric assessments through objective measurements. Among all participants, 5% had no health risk behaviors, 30% had one, 47% had two, and 18% had all three; their most common health risk behavior cluster was low physical activity and low fruit and vegetable consumption (28%). Among Puerto Rican men, 7% had no health risk behaviors, 24% had one, 51% had two, and 18% had all three; their most common health risk behavior cluster was current smoker and low fruit and vegetable consumption (28%). Among Mexican men, 3% had no health risk behaviors, 36% had one, 43% had two and 19% had all three; their most common health risk behavior cluster was low physical activity and low fruit and vegetable consumption (33%). The findings highlight the need for lifestyle interventions that target multiple health risk behaviors related to cardiometabolic diseases in Latinos.

RESUMO

This study examined the logistical, practical, and cultural preferences of Latinos regarding the design of a healthy eating, physical activity, and body image intervention. Puerto Rican and Mexican men (n = 203) completed an interview as part of an NIH-funded study. Overall, 66.5% preferred the intervention to be in Spanish only or both Spanish and English; 88.67% said it was moderately, very or extremely important for the intervention leader to be bilingual; and 66.01% considered it moderately to extremely important for the leader to be Hispanic or Latino. Most participants (83.74%) reported they would be willing to attend an intervention that met twice per week and 74.38% said they would be willing to attend an intervention that met for 1.5 to 2 h, twice weekly. Overall, the majority said they would be moderately to extremely interested in attending an exercise program if it consisted of aerobics with Latin or salsa movements (74.88%) and if it consisted of aerobics with Latin or salsa music (70.44%). Some participants were moderately to extremely interested in attending an intervention if it included dichos (Latino sayings) (65.02%) and cuentos (folktales or stories) (69.46%). The findings have implications for lifestyle and body image interventions aimed at preventing cardiometabolic diseases.

RESUMO

Triple-negative/basal-like breast cancer (BC) is characterized by aggressive biological features, which allow relapse and metastatic spread to occur more frequently than in hormone receptor-positive (luminal) subtypes. The molecular complexity of triple-negative/basal-like BC poses major challenges for the implementation of targeted therapies, and chemotherapy remains the standard approach at all stages. The matricellular protein cysteine-rich angiogenic inducer 61 (CCN1/CYR61) is associated with aggressive metastatic phenotypes and poor prognosis in BC, but it is unclear whether anti-CCN1 approaches can be successfully applied in triple-negative/basal-like BC. Herein, we first characterized the prevalence of CNN1 expression in matched samples of primary tumors and metastatic relapse in a series of patients with BC. We then investigated the biological effect of CCN1 depletion on tumorigenic traits in vitro and in vivo using archetypal TNBC cell lines. Immunohistochemical analyses of tissue microarrays revealed a significant increase of the highest CCN1 score in recurrent tissues of triple-negative/basal-like BC tumors. Stable silencing of CCN1 in triple-negative/basal-like BC cells promoted a marked reduction in the expression of the CCN1 integrin receptor αvß3, inhibited anchorage-dependent cell growth, reduced clonogenicity, and impaired migration capacity. In an orthotopic model of triple-negative/basal-like BC, silencing of CCN1 notably reduced tumor burden, which was accompanied by decreased microvessel density and concurrent induction of the luminal epithelial marker E-cadherin. Thus, CNN1/CYR61-targeting strategies might have therapeutic value in suppressing the biological aggressiveness of triple-negative/basal-like BC.

RESUMO

OBJECTIVE: To compare outcomes of obese and nonobese pediatric patients with acute promyelocytic leukemia (APL) from the Cancer and Leukemia Group B trial (CALGB) 9710 and the Children's Oncology Group trial AAML0631. METHODS: Data including demographics, adverse events, overall and event-free survival (EFS) were analyzed. RESULTS: The prevalence of obesity was 34% on C9710 and 35% on AAML0631. There was significantly lower overall and EFS in the obese population on multivariable analysis on AAML0631 but not on CALGB 9710. Eleven patients died during therapy or in follow-up. CONCLUSION: The prevalence of obesity is higher in pediatric patients with APL compared to the general population. The decreased EFS and OS in obese patients on AAML0631 suggest that the presence of obesity can influence outcomes using the most current treatment. These findings support the need for further research on the potential role of obesity in pediatric APL leukemogenesis.

RESUMO

PURPOSE: Angiosarcomas represents a diverse group of aggressive high-grade vascular tumours with limited therapeutic options. We sought to determine the safety and efficacy of regorafenib, a small-molecule multikinase inhibitor, in the treatment of metastatic or locally advanced unresectable angiosarcoma. PATIENTS AND METHODS: In this single-arm multicentre, open-label phase II clinical trial, 31 patients were enrolled and received regorafenib 160 mg PO daily for 21 days of a 28-day cycle. The primary endpoint for the study was progression-free survival at 4 months. Secondary endpoints included overall survival, response rate, and safety. Patients (≥18 years) with an Eastern Cooperative Oncology Group (ECOG) score of 0-1, a life expectancy of at least 4 months who had progressed on at least one but no more than 4 prior lines of therapy were eligible. RESULTS: Of the 23 patients evaluable for efficacy, 2 had a complete response (8.7%), and 2 had a partial response (8.7%), for a total overall response rate of 17.4%. Median PFS was 5.5 months, and 12/23 patients (52.2%) had a PFS of greater than 4 months. 10/31 (32.3%) patients evaluable for toxicity had a grade 3 or higher adverse events. CONCLUSIONS: Regorafenib is a safe and active treatment for refractory metastatic and unresectable angiosarcoma. Rates of adverse events were comparable to prior studies of regorafenib for other tumour types. Regorafenib, the single agent, could be considered as therapy for patients with metastatic or unresectable AS.

RESUMO

PURPOSE: To evaluate the effect of the anatomic size on 3D radiomic imaging features of the breast cancer hepatic metastases. MATERIALS AND METHODS: CT scans of 81 liver metastases from 54 patients with breast cancer were evaluated. Ten most common 3D radiomic features from the histogram and gray level co-occurrence matrix (GLCM) categories were calculated for the hepatic metastases (HM) and compared to normal liver (NL). The effect of size was evaluated by using linear mixed-effects regression models. The effect of size on different radiomic features was analyzed for both liver lesions and background liver. RESULTS: Three-dimensional radiomic features from GLCM demonstrate an important size dependence. The texture-feature size dependence was found to be different among feature categories and between the HM and NL, thus demonstrating a discriminatory power for the tissue type. Significant difference in the slope was found for GLCM homogeneity (NL slope = 0.004, slope difference 95% confidence interval [CI] 0.06-0.1, p <0.001), contrast (NL slope = 45, slope difference 95% CI 205-305, p <0.001), correlation (NL slope = 0.04, slope difference 95% CI 0.11-0.21, p <0.001), and dissimilarity (NL slope = 0.7, slope difference 95% CI 3.6-5.4, p <0.001). The GLCM energy (NL slope = 0.002, slope difference 95% CI -0.0005 to -0.0003, p <0.007), and entropy (NL slope = 1.49, slope difference 95% CI 0.07-0.52, p <0.009) exhibited size-dependence for both NL and HM, although demonstrating a difference in the slope between themselves. CONCLUSION: Radiomic features of breast cancer hepatic metastasis exhibited significant correlation with tumor size. This finding demonstrates the complex behavior of imaging features and the need to include feature-specific properties into radiomic models.

RESUMO

BACKGROUND: Lymphopenia has been associated with inferior cancer outcomes, but there is limited data in breast cancer. We describe the effects of neoadjuvant chemotherapy on circulating immune cells and its association with pathological complete response (pCR) rates in triple negative breast cancer (TNBC). METHODS: We constructed a database of patients with early stage TNBC treated with neoadjuvant chemotherapy. Circulating lymphocytes and monocytes were assessed before and after neoadjuvant chemotherapy. These were correlated with pCR rates and disease-free survival (DFS) using Fisher's exact test, logistic regression, and the log-rank test. RESULTS: From 2000 to 2015, we identified 95 eligible patients. Median age was 50; 29 (31%) were treated with platinum-containing chemotherapy; and 66 (69%) with nonplatinum-containing chemotherapy (anthracycline-taxane, or either alone). About 32 (34%) patients achieved a pCR; and 33 (35%) had recurrence events. Median follow-up time was 47 months. No significant associations were found between changes in lymphocytes and pCR or DFS. There was a correlation between lower monocyte levels after neoadjuvant chemotherapy and pCR (mean monocyte 0.56 in those with no-pCR vs 0.46 in those with pCR, P = .049, multivariate P = .078) and DFS (median DFS in highest monocyte quartile was 30 vs 107 months in lowest quartile, P = .022, multivariate P = .023). In patients who received nonplatinum regimens, DFS was better among those who had larger decreases in monocytes. CONCLUSIONS: Development of lymphopenia from neoadjuvant chemotherapy was not associated with pCR in patients with TNBC. However, lower absolute circulating monocytes after neoadjuvant chemotherapy was associated with improved outcomes.

RESUMO

ABSTRACT: Clinical health outcomes and health disparities can be improved through interprofessional collaborations among multidisciplinary clinicians, health care services researchers, and patients. Bridging gaps between community clinics and urban academic centers allows added valuable perspectives that can lead to improved care and extend clinical research. Nurse practitioners (NPs) who serve as primary care providers in many rural community clinics can facilitate access to clinical trials for patients who are rarely included in health care services research as well as coordinate interprofessional research team collaboration. A NP working in a rural clinic can assist academic-based research teams in designing feasible strategies to address disparities and improve health care of underserved populations. The purpose of this article was to provide an example of a rural provider/urban academic research team collaborating to conduct a health literacy-directed randomized controlled trial to improve colorectal cancer screening in isolated rural community clinics.

RESUMO

BACKGROUND: Response rates to single agent immune checkpoint blockade in unselected pretreated HER2-negative metastatic breast cancer (MBC) are low. However, they may be augmented when combined with chemotherapy. METHODS: We conducted a single-arm, phase II study of patients with triple negative (TN) or hormone receptor-positive endocrine-refractory (HR+) MBC who were candidates for capecitabine. Patients were treated with pembrolizumab 200 mg intravenously day 1 and capecitabine 1000 mg/m2 by mouth twice daily on days 1-14 of a 21-day cycle. The primary end point was median progression-free survival (mPFS) compared with historic controls and secondary end points were overall response rate (ORR), safety and tolerability. The study had 80% power to detect a 2-month improvement in mPFS with the addition of pembrolizumab over historic controls treated with capecitabine alone. RESULTS: Thirty patients, 16 TN and 14 HR+ MBC, were enrolled from 2017 to 2018. Patients had a median age of 51 years and received a median of 1 (range 0-6) prior lines of therapy for MBC. Of 29 evaluable patients, the mPFS was 4.0 (95% CI 2.0 to 6.4) months and was not significantly longer than historic controls of 3 months. The median overall survival was 15.4 (95% CI 8.2 to 20.3) months. The ORR was 14% (n=4), stable disease (SD) was 41% (n=12) and clinical benefit rate (CBR=partial response+SD>6 months) was 28% (n=8). The ORR and CBR were not significantly different between disease subtypes (ORR 13% and 14%, CBR 25% and 29% for TN and HR+, respectively). The 1-year PFS rate was 20.7% and three patients have ongoing responses. The most common adverse events were low grade and consistent with those seen in MBC patients receiving capecitabine, including hand-foot syndrome, gastrointestinal symptoms, fatigue and cytopenias. Toxicities at least possibly from pembrolizumab included grade 3 or 4 liver test abnormalities (7%), rash (7%) and diarrhea (3%), as well as grade 5 hepatic failure in a patient with liver metastases. CONCLUSIONS: Compared with historical controls, pembrolizumab with capecitabine did not improve PFS in this biomarker unselected, pretreated cohort. However, some patients had prolonged disease control. TRIAL REGISTRATION NUMBER: NCT03044730.

RESUMO

INTRODUCTION: The vast majority of patients who undergo a diagnostic evaluation for microscopic hematuria (MH) do not have occult bladder cancer. Identifying patients with MH at high risk of harboring bladder cancer can allow for a risk adjusted approach to diagnostic interventions with the goal of safely reducing unnecessary evaluations. METHODS: Patients with a new diagnosis of microhematuria during an 8.5 year period were retrospectively identified. All patients who had a complete MH evaluation were randomized to a training or a validation cohort. Logistic regression analysis was performed in the training cohort to identify factors related to a bladder cancer diagnosis and to develop our model. Receiver operating curves to identify bladder cancer were constructed for the training and validation cohort and tested for their ability to discriminate true cases. A nomogram to predict a bladder cancer diagnosis was created. RESULTS: In 4,178 patients split into training and validation cohorts, those diagnosed with bladder cancer were shown to be older, have a greater degree of MH (more RBC/hpf), and were former or current smokers. A nomogram created using this model was able to predict risk of a bladder cancer diagnosis with good discrimination (areas under the curve 0.79, 95% CI 0.75-0.83). A cutoff of 0.01 probability demonstrated a sensitivity of 99.1% and a negative predictive value of 99.7%. CONCLUSION: A nomogram can accurately predict the risk of bladder cancer diagnosed during the evaluation of MH and can potentially be used avoid a significant number of work ups in those at the lowest risk.

RESUMO

Introduction: While the incidence of skin cancers continues to rise, there remains a disproportionate lack of introductory training on skin cancer screening and identification of modifiable behaviors in medical curricula. Trainees and students have cited low confidence in their ability to counsel patients and lack of instruction as barriers. Methods: To address this need, we created a 1-hour didactic lecture based on a cognitive teaching framework for third-year medical students during their core primary care clerkship. The session highlighted visual identification of different skin cancers, factors increasing individual risk, and photoprotective behaviors. Session content was based on American Academy of Dermatology recommendations for skin cancer prevention. An assessment of knowledge, behaviors, and attitudes given before, immediately following, and at 6 months after the session was used to determine efficacy. Results: One hundred eight students before and immediately after the session demonstrated significantly improved knowledge (mean correct: 71% presession vs. 99% postintervention, p < .0001). Based on 39 participants completing 6-month follow-up, knowledge remained improved (mean answered correctly: 80%, p < .0001). Confidence in patient counseling on preventive behaviors, risk assessment, and reported likelihood of counseling significantly increased across the three time points (p < .0001 for all attitude questions). Specific topics included appropriate referral to a dermatologist, sunscreen application, and dangers of indoor tanning bed usage. Discussion: Our session on skin cancer screening and prevention demonstrated improvements in medical student knowledge, confidence, and patient counseling likelihood. This introductory curriculum could be adapted for multiple core clerkships or specialties.

RESUMO

This trial tested a multicomponent intervention to increase colorectal cancer (CRC) screening among underserved patients. Participants were randomized to: (1) physician + patient intervention, (2) physician-only intervention, or (3) usual care (UC). Study outcomes included patient knowledge, physician recommendation of CRC screening, and screening completion via colonoscopy or stool tests. Among 538 participants, those exposed to the physician + patient intervention had significantly increased knowledge over patients in physician-only (p=.0008) or UC arms (p=.0003). However, there were no statistically significant differences in completion of CRC screening, with 10%, 20%, and 16% of UC, physician-only, and physician + patient participants screened, respectively. In UC, all completed screenings were colonoscopy, whereas in the physician-only and physician + patient arms, 39% and 46% of completed tests were via stool test, respectively. The multicomponent intervention did not increase overall CRC screening, yet results underscore the need to provide patients options for completing CRC screening.

RESUMO

As cancer survival rates continue to increase, so does the relevance of starting or expanding a family after cancer, impacting quality of life. However, the option of fertility preservation is not always addressed by physicians before treatment. In the meanwhile, many patients look for health information online. Although potentially helpful in the decision-making process, the Internet could also have adverse effects for this vulnerable patient group when information is incorrect. We aimed to assess the availability and quality of information on female oncofertility on websites of (inter)national oncology, fertility and oncofertility organizations. Availability was identified using an original checklist. Quality was measured by reliability (DISCERN and LIDA instruments), usability (LIDA instrument), and readability (Flesch Kincaid Grade Level test). Of all investigated websites, 52% contained information on oncofertility, with 32% containing a stand-alone page. Of those sites, the amount of treatment options covered were equivalent between specialty sites and general fertility and oncology sites (p = 0.07). The quality of information on treatment choices was the highest for oncofertility websites. Reliability and usability did not differ significantly between websites. No websites evaluated were at the recommended 7th-8th grade reading level. Availability and quality should be improved, and high-quality resources are recommended by physicians.

RESUMO

PURPOSE: The majority of colorectal cancer (CRC) research using the fecal immunochemical test (FIT) has studied short-term screening results in predominantly urban areas. The purpose of this study was to evaluate the effectiveness of 2 outreach strategies embedded in a health literacy intervention on repeat CRC screening in rural community clinics. METHODS: A 2-arm randomized controlled trial was conducted in 4 rural clinics in Louisiana. During a regularly scheduled clinic visit, participants ages 50-75 received a FIT kit and brief educational intervention. Participants were randomized to receive an automated call or a personal call by a prevention counselor after 4 weeks and 8 weeks if FIT kits were not returned. In year 2, materials were mailed, and follow-up calls were conducted as in year 1. The primary outcome was repeat FIT-the return of the FIT kit in both years. PARTICIPANTS: Of 568 eligible participants, 55% were female, 67% were African American, and 39% had low health literacy. FINDINGS: Repeat FIT rates were 36.5% for those receiving the automated call and 33.6% for those receiving a personal call (P = .30). No annual FITs were returned in 30% of participants, while only 1 FIT was returned by 35% of participants (31% only year 1 and 4% only year 2). CONCLUSION: Sustaining CRC screening with FIT is challenging in rural clinics. A lower cost automated call was just as effective as the personal call in promoting repeat annual screening. However, more intensive strategies are needed to improve long-term FIT screening among rural participants.

RESUMO

Human papillomavirus (HPV)-positive head and neck squamous cell carcinoma (HNSCC) is biologically distinct from HPV-negative HNSCC. Outside of HPV-status, few tumor-intrinsic variables have been identified that correlate to improved survival. As part of exploratory analysis into the trace elemental composition of oropharyngeal squamous cell carcinoma (OPSCC), we performed elemental quanitification by X-ray fluorescence microscopy (XFM) on a small cohort (n = 32) of patients with HPV-positive and -negative OPSCC and identified in HPV-positive cases increased zinc (Zn) concentrations in tumor tissue relative to normal tissue. Subsequent immunohistochemistry of six Zn-binding proteins-zinc-α2-glycoprotein (AZGP1), Lipocalin-1, Albumin, S100A7, S100A8 and S100A9-revealed that only AZGP1 expression significantly correlated to HPV-status (p < 0.001) and was also increased in tumor relative to normal tissue from HPV-positive OPSCC tumor samples. AZGP1 protein expression in our cohort significantly correlated to a prolonged recurrence-free survival (p = 0.029), similar to HNSCC cases from the TCGA (n = 499), where highest AZGP1 mRNA levels correlated to improved overall survival (p = 0.023). By showing for the first time that HPV-positive OPSCC patients have increased intratumoral Zn levels and AZGP1 expression, we identify possible positive prognostic biomarkers in HNSCC as well as possible mechanisms of increased sensitivity to chemoradiation in HPV-positive OPSCC.

RESUMO

BACKGROUND: Patients with acute myeloid leukemia (AML) are surviving longer. There are no data on changes in myocardial mechanics from standard of care low-dose anthracycline-based induction chemotherapy in older patients with AML. The aim of this study was to demonstrate the potential utility of strain imaging in detecting early changes in left ventricular function in this patient population after induction chemotherapy. METHODS: Thirty two patients enrolled in the ECOG-ACRIN E2906 study (cytarabine and daunorubicin vs clofarabine [Genzyme/Sanofi]) from 2011 to 2014 were evaluated retrospectively. Two-dimensional transthoracic echocardiography (TTE) imaging with Doppler and two-dimensional speckle-tracking echocardiography (2DSTE) using EchoInsight software (Epsilon imaging) were performed before and after induction chemotherapy. RESULTS: Eighteen patients received cytarabine and daunorubicin (7 + 3) and 14 received clofarabine. The clofarabine group was older than the 7 + 3 cohort (67.8 ± 4.0 vs 63.7 ± 3.8, P = .007). There were no other significant differences in cardiac risk factors between groups. The 7 + 3 group had a decrease in average peak systolic global longitudinal (-19.1 ± 2.8 to -17.2 ± 3.0, P = .01) and circumferential strain (-29.4 ± 6.3 to -23.9 ± 4.3, P = .011). These changes were not demonstrated in the clofarabine group and were not associated with a decline in left ventricular ejection fraction (LVEF). CONCLUSIONS: In older AML patients, standard cytarabine and daunorubicin chemotherapy causes early changes in global longitudinal and circumferential strain not seen with clofarabine therapy. These findings demonstrate subclinical left ventricular dysfunction after exposure to low cumulative doses of anthracycline-based induction chemotherapy and may help us better identify those patients at risk for adverse long-term cardiovascular outcomes.

RESUMO

We examined if urinary angiotensinogen (uAOG), a marker of intrarenal renin-angiotensin system activity, antedates stage 3 chronic kidney disease (CKD) using samples from participants in the Diabetes Control and Complications Trial (DCCT) and later in the Epidemiology of Diabetes Intervention and Complications (EDIC) trial. In a nested case-control design, cases were matched at the outcome visit (eGFR less than 60, 21-59 mL/min per 1.73 m2 ) on age, gender, and diabetes duration, with controls: eGFR (95, 75-119, mL/min per 1.73 m2 .) Additionally, in an exploratory analysis progressive renal decline (PRD), defined as eGFR loss >3.5 mL/min per 1.73m2 /year, was evaluated using only data from EDIC because no progressions were observed during DCCT. At the EDIC visit, which antedated the GFR outcome visit by 2 years (range 1-7years) the median uAOG/creatinine was markedly higher in cases than in controls (13.9 vs. 3.8 ng/mg P = 0.003) whereas at the DCCT visit, which antedated the GFR outcome by 17 to 20 years it was not (2.75 vs. 3.16 ng/mg, respectively). The Odds Ratio for uAOG and CKD stage 3 development was significant after adjusting for eGFR, HbA1c, and systolic blood pressure 1.82 (1.00-3.29) but no longer significant when Albumin Excretion Ratio (AER) was included 1.21 (0.65-2.24).In the PRD analysis, uAOG/creatinine was sixfold higher in participants who experienced PRD than in those who did not (26 vs. 4.0 ng/mg, P = 0.003). The Odds Ratio for uAOG and PRD was significant after adjusting for eGFR, HbA1c, and systolic blood pressure 2.48 (1.46-4.22) but no longer significant when AER was included 1.32 (0.76-2.30). In people with type1 diabetes, a robust increase in uAOG antedates the development of stage 3 CKD but is not superior to AER in predicting this renal outcome. Increased uAOG moreover is associated with PRD, an index of progression to End Stage Kidney Disease (ESKD).

RESUMO

CONTEXT: Uterine leiomyoma (fibroids) are the most common tumors in women. Recently, perilipin-2 (PLIN2) was identified as a critical target gene of the progesterone receptor; however, its function in the pathogenesis of fibroids is unknown. OBJECTIVE: To determine the function of PLIN2 in leiomyoma cells. DESIGN: Tissue and primary cells from leiomyoma and myometrium were analyzed. PLIN2 function in leiomyoma was assessed using small interfering RNA. RNA-sequencing was performed to identify genome-wide effects of PLIN2 depletion. Metabolic activity was measured using the Seahorse XF96 analyzer. Real-time quantitative PCR and immunoblotting were also performed. SETTING: Laboratory. PATIENTS OR OTHER PARTICIPANTS: Forty-one premenopausal women undergoing surgery for fibroids. MAIN OUTCOME MEASURES: Gene expression, oxygen consumption rate (OCR), extracellular acidification rate (ECAR), and cell proliferation. RESULTS: PLIN2 gene expression was 2.4-fold lower in leiomyoma compared with adjacent myometrium, suggesting a link between PLIN2 deficiency and fibroids. A total of 3877 genes were differentially expressed after PLIN2 knockdown. Gene ontology analysis identified metabolism as the second-highest biological process affected by PLIN2 depletion. OCR (mitochondrial respiration) and ECAR (glycolysis) were significantly upregulated after PLIN2 knockdown; PLIN2-depleted cells had a greater basal metabolic activity and higher metabolic stress response. Cell proliferation was also significantly increased after PLIN2 knockdown. CONCLUSIONS: PLIN2 depletion increases mitochondrial respiration and glycolysis, suggesting that PLIN2 is a critical regulator of metabolic function in leiomyoma cells. PLIN2 deficiency also reprograms leiomyoma cells to a proproliferative phenotype. These findings introduce metabolomics as an area to explore to better understand leiomyoma tumorigenesis.

RESUMO

BACKGROUND: Overweight and obesity is a significant public health concern among Latino men. Common correlates of obesity that have been examined in previous studies are diet, physical activity, and body image. OBJECTIVES: The aim of this study was to examine whether or not there are differences in body image, physical activity and cultural variables between Mexican and Puerto Rican men. METHODS: Participants completed a health and culture interview, anthropometric measures, a dietary assessment, and an objective measure of physical activity. The results are from the 203 participants who completed the health and culture interview. RESULTS: Mexicans and Puerto Ricans did not differ in their current and ideal body image, body image discrepancy, body satisfaction or how they described their weight. Puerto Ricans watched a greater number of hours of television per day than Mexicans (p < .01). There were no significant differences in their participation in any regular activity designed to improve or maintain their physical fitness, the number of times or length they engaged in this activity, or in their perceived exertion during this activity. Puerto Ricans reported a higher level of familism (p < .01) and machismo (p < .05) than Mexicans. There were no ethnic differences in folk illness beliefs, fatalism or personalism, acculturation level, acculturative stress, or ethnic identity. CONCLUSIONS: Results are discussed in relation to the development of healthy eating, physical activity and body image interventions for Puerto Rican and Mexican men.
