Background Exposure to violence has negative consequences on mental health. Armed-conflict in Colombia widely affected Afro-descendants the Pacific region. Evidence regarding effectiveness of health interventions is lacking low-income settings, especially areas with active conflict. The objective this study evaluate an individualized Common Elements Treatment Approach (CETA), a transdiagnostic psychotherapy model based Cognitive-Behavioral Therapy, for adult trauma survivors. Methods and...
BACKGROUND The objective of the current study was to examine how modifiable factors such as satisfaction with cancer care and self‐efficacy impact health‐related quality life (HRQOL) among Latino survivors. METHODS Latinos previously diagnosed breast, prostate, or colorectal ( N = 288) completed questionnaires (Patient Satisfaction Cancer Care Scale, Stanford Chronic Disease Self‐Management Measures, Functional Assessment Therapy‐General, Short Acculturation Scale for Hispanics) within 2...
BACKGROUND The interaction of clinical and patient‐level challenges following a breast cancer diagnosis can be significant source health care disparities. Failure to address specific cultural features that create or exacerbate barriers lead less‐than optimal navigation results, specifically in Hispanic/Latino women. METHODS To these disparities, the study leaders San Antonio, Texas, 5 other regional partners federally‐funded Redes En Acción: National Latino Cancer Research Network developed...
Background: Cancer disparities among Latinos in the US are a critical public health issue, with this group experiencing inequitable outcomes across cancer continuum, from screening to end-of-life care. have higher rates of certain cancers and poorer compared other populations, driven by complex interplay environmental, genetic, cultural, behavioral, systemic factors. While earlier research has highlighted some these disparities, comprehensive analyses multilevel factors affecting care still...
Background: Inclusion of minorities in clinical research is an essential step to develop novel cancer treatments, improve health care overall, understand potential differences pharmacogenomics and address minorities' disproportionate burden. However, Latinos other minority groups continue be critically underrepresented, particularly EPCTs. The objective the present study was explore barriers promoting factors influencing patients' decisions enroll or not early phase trials (EPCTs) identify...
Groups of mice were inoculated with six Trypanosoma cruzi strains and then treated 32 mg/kg body weight allopurinol for 10 consecutive days. Effects the drug on mortality rates closely evaluated repeated fresh blood examinations done. Infected showed at least four parasitemia patterns varied levels. Evidence is provided that, independently pattern or level strain origin, there are marked differences in sensitivity to between several T. studied. These response seem be related biological...
Background Hepatocellular carcinoma (HCC) is increasing in the U.S. despite a decline cancer overall. Latinos have higher rates of HCC than general population according to Surveillance, Epidemiology, and End Results (SEER) Program. Not included SEER, Texas make up one-fifth Latino population. To determine whether incidence differs among Latinos, this descriptive study compares from 1995 through 2006 three populations: overall South subset. identify lines prevention research, we compare...
Background A previous study showed Hepatocellular Carcinoma (HCC) rates to be higher among Latinos in Texas and highest South compared other non-Hispanic whites (NHW) the United States (U.S.). We used more recent data assess trends HCC reassess elevated incidence rate Latinos. Methods from U.S. SEER Program Cancer Registry calculate annual 3-year moving average age-specific age-adjusted rates, percent changes (APCs), their corresponding 95% confidence intervals for NHW U.S., Texas. Results...
Adjuvant endocrine hormonal therapy (EHT) is highly effective and appropriate for nearly all breast cancer patients with hormone receptor-positive tumors, which represent 75% of diagnoses. Long-term use EHT reduces recurrence rates halves the risk death during second decade after diagnosis. Despite proven benefits, about 33% women receiving do not take their medication as prescribed. This causes an increase in death. To promote adherence to among patients, this study will develop pilot-test...
Background After a diagnosis of prostate, breast, or colorectal cancer, Latinos experience higher mortality rates and lower health‐related quality life (HRQOL) in comparison with other ethnic/racial groups. Patient navigation (PN) lay community health workers promotores are effective increasing cancer screening early‐stage among Latinos. However, little is known about the effect PN on HRQOL Latino survivors. Methods previously diagnosed (n = 288) were randomized to 1 2 conditions: 1)...

Abstract BACKGROUND. Breast cancer is the leading cause of cancer‐related deaths in Latinas, chiefly because later diagnosis. The time from screening to diagnosis critical optimizing care, yet efficacy navigation reducing it insufficiently documented. Here, authors evaluate a culturally sensitive patient program reduce and increase proportions women diagnosed within 30 days 60 days. METHODS. analyzed 425 Latinas who had Imaging Reporting Data System (BI‐RADS) radiologic abnormalities...
Time delay after an abnormal screening mammogram may have a critical impact on tumor size, stage at diagnosis, treatment, prognosis, and survival of subsequent breast cancer. This study was undertaken to evaluate disparities between Latina non-Hispanic white (NHW) women in time definitive diagnosis cancer mammogram, as well factors contributing such disparities. As part the activities National Cancer Institute (NCI)-funded Redes En Acción research network, clinical records 186 Latinas 74...
Abstract Introduction Breast cancer survivorship is a life‐long process involving challenges to health‐care communities and individuals, especially Latinas. Patient Navigation has shown some success in meeting these challenges. The purpose of this study was compare the effects an enhanced program (Intervention; PN+) vs Control (PN) over time on general breast cancer‐specific quality life (QoL) Latina survivors (BCS). Methods We conducted 2‐year, two‐arm randomized controlled trial “Staying...
Abstract Background Patient navigation (PN) is a promising yet underused approach to address Hispanic/Latino (H/L) cancer survivors' unmet supportive care needs. The authors conducted randomized trial evaluate the effect of culturally tailored PN program with LIVESTRONG Foundation's Cancer Navigation Services (PN‐LCNS) on reducing needs in H/L survivors. Methods From 2012 2015 at two US sites, 288 survivors diagnosed breast, prostate, or colorectal were PN‐LCNS standard PN. Participants...

Background: Physician referral is among the most effective means of recruiting patients into cancer clinical trials. Therefore, to increase minority representation in early-phase trials (EPCTs), specifically accrual Latinos, it first necessary examine physicians’ attitudes and practices regarding these studies factors that influence decisions. Methods: This study surveyed oncologists (N=111) from a Texas Medical Association mailing list barriers promoting associated with physician EPCTs...
