RESUMEN

Social determinants of health contribute to health disparities and inequities. We conducted a community forum on the topic of isolation with the objectives of (1) identifying and prioritizing key health-related issues needing attention in isolated communities in Puerto Rico; (2) developing strategies in terms of Policies, Programs, and Practices to address the community priorities we identified. We used the triangulation method for qualitative data, integrating the Colorado State University's Tri-ethnic Center Model and the Delphi Technique for a better understanding of community health needs and priorities. The five community health-related priorities identified in the community forum were: (1) access to health services (physical and mental); (2) older adults; (3) access to basic services; (4) preparedness for future disasters/emergencies; and (5) COVID-19 and access to vaccination. The Alliance Leaders and Advisory Boards understand that we will work with the priorities of preparedness for future natural disasters/emergencies and COVID-19 and access to vaccination. Fifteen strategies were developed for these priorities and were grouped into five areas that require more attention in order to reduce health disparities. Isolated communities in Puerto Rico present an intersectionality of factors that affect a wide range of health-related risks and outcomes.

RESUMEN

PURPOSE: The purpose of this study was to compare the safety, efficacy, and efficiency of a Descemet membrane endothelial keratoplasty (DMEK) graft processing device, DescePrep, with a manual dissection technique through the measurement of tissue yield, processing time, and graft viability in nondiabetic and diabetic donor corneas. METHODS: Nondiabetic (n = 20) and diabetic (n = 20) donor corneas were processed using DescePrep, which standardizes the liquid bubble technique. Nondiabetic (n = 20) and diabetic (n = 24) donor corneas were also processed through manual dissection. Corneas were stained, processed, and then evaluated for processing success rate and time. Randomly selected corneas (n = 5, each) were evaluated for cell viability using live/dead staining. RESULTS: One hundred percent of nondiabetic and 95% of diabetic corneas were processed successfully with DescePrep in an average of 3.37 minutes. Ninety percent of nondiabetic and 50% of diabetic corneas were processed successfully with manual dissection in an average of 9.87 minutes. DescePrep had a significantly lower processing time ( P < 0.0001) and significantly higher success rate in comparison with manual dissection. DescePrep grafts had an average cell viability of 91.1% ± 3.3% in nondiabetic and 91.5% ± 2.4% in diabetic corneas. Grafts prepared with manual dissection had an average cell viability of 89.5% ± 5.8% in nondiabetic and 88.1% ± 4.3% in diabetic corneas. CONCLUSIONS: DescePrep provides a more effective and efficient method of cornea preparation in comparison with the current standard, particularly in diabetic corneas, while providing comparable cell viability. Thus, DescePrep offers standardized DMEK processing that produces high-quality grafts at high yields, with the potential to expand access and improve the quality of DMEK graft preparation in a larger pool of donors.

RESUMEN

PURPOSE: The purpose of this study was to evaluate the safety, efficacy, and efficiency of a Descemet membrane endothelial keratoplasty (DMEK) graft preparation device, DescePrep, through measurement of graft viability, yield, and preparation time in both healthy and diabetic (high-risk) donor eyes. METHODS: Twenty nondiabetic and 10 diabetic donor corneas were processed using DescePrep, which standardizes the liquid bubble technique. Corneas were stained with trypan blue and then processed. Cell counts through specular microscopy, optical coherence tomography imaging, and slit-lamp analysis were used for the evaluation of graft separation and viability in 5 nondiabetic corneas. The remaining 25 corneas (15 nondiabetic and 10 diabetic) were evaluated for preparation success rate and processing time. Ten corneas (5 nondiabetic and 5 diabetic) were randomly selected for further evaluation of global cell loss through staining. RESULTS: Ninety-seven percent of corneas (29 of 30) were prepared successfully with DescePrep. The average preparation time was 2.83 ± 1.8 minutes. There was no significant difference in the time of preparation between the nondiabetic and diabetic groups (P = 0.077). The overall average cell death after processing was 7.9% ± 3.7% for all corneas. There was no significant difference in cell viability between diabetic and nondiabetic tissues after DescePrep processing (P = 0.769). CONCLUSIONS: DescePrep is a new DMEK preparation technique that can process both nondiabetic and diabetic donor corneas at high yields in minutes. High-yield preparation of diabetic corneas may offer eye banks access to a larger donor pool, which is important because the demand for DMEK grafts continues to rise worldwide.

RESUMEN

Functional mitral regurgitation (FMR) is an insidious and poorly understood condition affecting patients with myocardial disease. While current treatments reduce regurgitation, their ability to reverse mitral valve pathology is unclear. We utilized a pseudo-physiological flow loop to study how repair impacted valve composition. Porcine mitral valves were cultured in control geometry (native papillary muscle position and annular area) or high-tension FMR geometry (5 mm apical and 5 mm lateral displacement of papillary muscles, 65% increased annular area) for 2 weeks. To mimic repair, a reversal condition was created by returning one-week FMR conditioned valves to a non-regurgitant geometry and culturing for 1 week. Valve composition and material properties were analyzed. After two-week culture, FMR conditioned tissues were stiffer and stronger than control and underwent extensive fibrotic remodeling, with increased prolyl-4-hydroxylase, lysyl oxidase, matrix metalloproteinase-1, and decorin. The reversal condition displayed a heterogeneous, leaflet- and orientation-dependent response. Reversal-conditioned anterior leaflets and circumferential tissue sections continued to have significant fibrotic remodeling compared to control, whereas reversal-conditioned posterior leaflets, chordae tendineae, and radial tissue sections had significantly decreased remodeling compared to FMR-conditioned tissues. These findings suggest current repairs only partially reverse pathology, underscoring the need for innovation in the treatment of FMR.

RESUMEN

BACKGROUND: We conducted a phase II study of oral capecitabine rapidly disintegrating tablets given concurrently with radiation therapy (RT) to assess progression-free survival (PFS) in children with newly diagnosed diffuse intrinsic pontine gliomas (DIPG). PATIENTS AND METHODS: Children 3-17 years with newly diagnosed DIPG were eligible. Capecitabine, 650 mg/m2 /dose BID (maximum tolerated dose [MTD] in children with concurrent radiation), was administered for 9 weeks starting the first day of RT. Following a 2-week break, three courses of capecitabine, 1,250 mg/m2 /dose BID for 14 days followed by a 7-day rest, were administered. As prospectively designed, 10 evaluable patients treated at the MTD on the phase I trial were included in the phase II analyses. The design was based on comparison of the PFS distribution to a contemporary historical control (n = 140) with 90% power to detect a 15% absolute improvement in the 1-year PFS with a type-1 error rate, α = 0.10. RESULTS: Forty-four patients were evaluable for the phase II objectives. Capecitabine and RT was well tolerated with low-grade palmar plantar erythrodyesthesia, increased alanine aminotransferase, cytopenias, and vomiting the most commonly reported toxicities. Findings were significant for earlier progression with 1-year PFS of 7.21% (SE = 3.47%) in the capecitabine-treated cohort versus 15.59% (SE = 3.05%) in the historical control (P = 0.007), but there was no difference for overall survival (OS) distributions (P = 0.30). Tumor enhancement at diagnosis was associated with shorter PFS and OS. Capecitabine was rapidly absorbed and converted to its metabolites. CONCLUSION: Capecitabine did not improve the outcome for children with newly diagnosed DIPG.

RESUMEN

INTRODUCTION: Effective communication skills that foster responsible sexual decisions are known to have the potential to reduce the risky adolescent sexual behavior. It is well understood that maternal communication is a key element in modifying the adolescent sexual behavior. The objective of this qualitative study was to explore if Puerto Rican mothers of adolescent girls have conversations about sexuality with their daughters and the content of such conversations. METHODS: A total of 22 HIV-seropositive mothers and 22 HIV-seronegative mothers were enrolled. Six focus groups were conducted, sessions were transcribed ad-verbum and coded for specific topics. All qualitative analysis was incorporated into Atlas.ti. RESULTS: Participants in both groups had a similar average age (mean=41 years old); but, the HIV-seropositive mothers were more likely single, less educated and unemployed. Regarding having engaged in conversations about sexuality and the topics covered, however, there were no differences revealed among HIV-seropositive mothers and seronegative mothers. In both groups, mothers understood the importance of these conversations, but most said they were difficult and uncomfortable. CONCLUSION: These findings reinforce the importance of communication between mothers and daughters for the prevention of STIs, HIV/AIDS, and teenage pregnancy in minority populations.Interventions are needed for mother and daughter to improve communication skills, communication about sexuality, and addressing prevention.

RESUMEN

OBJECTIVE: "Arte con Salud" is an HIV/AIDS prevention intervention tailored for Puerto Rican women who have sex with men. The intervention curriculum was refined through a community-academic collaboration between Taller Salud, the UPRCayey Campus, and the UCC-School of Medicine, subsided in 2012-13 by PRCTRC. The collaboration has been crucial to validate the impact of using art as a tool to facilitate sexual negotiation skills and safer sexual practices among adult women have sex with men participating in HIV prevention education. METHODS: This article describes the vision, valley, victory phases endured to establish a community-academia partnership based on the CPPR framework as an effective mean to implement a randomized controlled trial intervention (RCT). We also discuss the barriers, outcomes, and lessons learned from this partnership. RESULTS: Some of the identified solutions include: setting goals to secure funding, regular meetings, and the inclusion of undergraduate level students to assist in the implementation of the intervention. These solutions helped to build trust among the community and academic partners. As a result of this collaboration, a total of 86 participants were enrolled and 5 competitive research grants have been submitted. CONCLUSION: The community-academic collaboration was essential in order to build a solid research infrastructure that addresses the complexities of HIV prevention education among groups of Puerto Rican women.

RESUMEN

BACKGROUND: This study evaluates the benefits of integrating behavioral health and trauma services for Latinas with a history drug use. Changes in quality of life (QOL) domains were documented after participation in a manualized intervention in a cohort of Latinas. METHODS: Participants were part of a prospective cohort study of 136 Latinas with co-occurring disorders (COD) who may have experienced trauma and receiving services in our outpatient treatment facility in Bayamón, Puerto Rico. The WHOQOL-BREF Spanish version was used to score physical, psychological, social, and environmental QOL domains, at intake and after six months. Sociodemographic variables, alcohol, drug use, mental health disorders, and severity of substance use disorders (as defined by the DSM-5) were also tabulated. Descriptive statistics and paired t test or the Wilcoxon signed-rank test were computed for comparison. RESULTS: A median age of 39 years was seen and with 76% high school education or higher degree. The majority were unemployed (95.9%). A diagnosis of severe cocaine use (51.4%) was present and almost half (49.5%) had three or more DSM-5 diagnoses. Mean QOL scores were higher at six months with statistically significant differences in each domain. Women with neurodevelopmental disorders and schizophrenia yielded higher mean QOL scores for each domain at six months except for the social domain. Women with polydrug use and women who reported exposure to trauma and depressive disorder experienced statistically significant increments in the physical, psychological and social domains in comparison to counterpart women. CONCLUSIONS: Significant and positive changes in QOL were found in each domain. Latinas who reported traumatic events had lower scores in the physical and psychological QOL domains. There was a high prevalence of diminished physical and mental functioning in Latinas with COD. The exposure to trauma and the lack of social support negatively affect treatment access and retention for Latinas.

RESUMEN

Hispanics are less likely to undergo screening tests for colorectal cancer and cervical cancer than non-Hispanic whites. Compliance with mammography, fecal occult blood testing (FOBT), colonoscopy, and cervical smears (PAP) and barriers for compliance were studied. A descriptive study was performed with 194 ambulatory patients while they attended routine medical visits. Women are more likely than men to undergo a colonoscopy. Conversely, FOBT was most likely reported by men. Reasons for compliance with FOBT differed by gender. Men were most likely to avoid FOBT due to lack of knowledge whereas women reported that physicians do not recommend the procedure. Both men and women reported that lack of physician's recommendation was their primary reason for not undergoing a colonoscopy. Men tend to report lack of knowledge about colonoscopy procedure. A higher mammogram utilization rate was reported by women older than 40 years. PAP smears were reported by 74% of women older than 21 years. The major reasons for avoiding mammography and PAP tests were having a busy schedule, fear, and feeling uncomfortable during the procedure. In a multivariate regression analysis, occupational status was found to be a predictor for compliance with FOBT and colonoscopy.

RESUMEN

The purpose of this manuscript is to assess and compare HIV risk behaviors among early adolescents after a three-year pilot study. A total of 135 public and private junior high schools students completed the intervention protocol. A self-administered questionnaire was given at baseline and at the end of the third year (fourth measure). Descriptive and inferential analyses were performed using SPSS 20.0. About 60% of the students were 14 years old at the fourth measure. The proportion of students that did not report at least one HIV risk behavior at baseline and those that reported any risk behavior at the fourth measure was lower in the intervention group (45.0%) than in the control group (54.5%). The proportion of students that reported at least one HIV risk behavior at baseline and those that did not report any HIV risk behavior at the fourth measure was higher in the intervention group than in the control group (33.3% vs. 8.3%). The proportion of students engaging in HIV risk behaviors was higher in the control group than in the intervention group at the fourth measure, suggesting that A Supportive Model for HIV Risk Reduction in Early Adolescence (ASUMA) intervention might be a promising initiative to reduce adolescents' engagement in HIV risk behaviors.

RESUMEN

The frequency of K-RAS mutations ranges between 30% and 48% among the Caucasian, Asian, and European populations and these mutations are predictors of response to EGFR therapies. We sought to determine the expression of K-RAS gene mutations among colorectal cancer patients in PuertoRico. A retrospective study was conducted to determine the expression of mutant K-RAS among colorectal cancer patients in Puerto Rico between April 2009 and January 2011. The mutant expression of K-RAS was found in 39% (n=195) of the Puerto Rican population, and was more common in the age group of 51-69 years (53.8%) and in males (55.4%, p>0.05). Moreover, mutant K-RAS was more commonly found in tumors of the proximal area (43.8%; p=0.03), with distant metastasis (43.3%, p=0.018), with a mucinous histotype (31.7% p>0.05), and in ulcerated tumors (38.8%, p>0.05). K-RAS mutations were observed on codon 12 (87.7%) and codon 13 (12.3%). The most frequent mutation on codon 12 was 12 ASP (39.5%), followed by 12 VAL (25.4%) that is associated with a significant decrease in overall cancer survival. The mutant expression of K-RAS in cases of rectum carcinoma was 39.5%, where the most common mutation was 12 VAL (37.5%). The frequency of K-RAS mutations in the Puerto Rican population here studied was 39% and mutant K-RAS was associated with advanced colorectal cancer stage, mucinous histotype, and ulcerated tumors.

RESUMEN

INTRODUCTION: Teenagers are the fastest growing group of newly HIV-infected persons. Consequently, a support model for HIV risk reduction was designed and implemented for early adolescents in Puerto Rico. OBJECTIVE: The purpose of this article is to assess changes in developmental factors and HIV risk behaviors among early adolescents after three years of follow-up of an intervention and a non-intervention group. METHODS: This prospective cohort study followed 135 early adolescents who were enrolled in the ASUMA (A Supportive Model for HIV Risk Reduction in Early Adolescents) Project. The study was performed in two public and two private junior schools. Baseline and three follow-up self-administered questionnaires were given. We examined sociodemographic factors, HIV risk behavior and developmental factors. RESULTS: 48% were in the intervention group and 51.1% were controls. Most adolescents were aged 12 years; 47.4% were males; 75.6% reported not having risk behaviors and 24.4% reported having risk behaviors at anytime in their lifespan. A significant decrease in the HIV risk behaviors median was observed among the intervention group (P < .05), while a nonsignificant increase was found among adolescents in the control group. At the end of the implementation phase, positive improvement in the developmental factors were observed in the intervention group (P < .05). CONCLUSIONS: Our study suggests that the ASUMA project curriculum had a positive effect on developmental factors and HIV risk behaviors, as proposed in our conceptual framework. Also, this study illustrates the importance of the creation of culturally appropriate instruments and interventions to reach the goal of HIV/AIDS reduction.
