Full textAbstract:
With a total of more than 150,000 specimens, the 85-year old collections of insects and terrestrial, freshwater, and marine invertebrates of the University of Puerto Rico at Mayagüez (UPRM), western Puerto Rico, are among the most significant repositories for these groups in the Caribbean region. Located in Mayagüez and on Magueyes Island, these collections were created by outstanding insect and invertebrate specialists working in Puerto Rico and surrounding islands. Holdings are particularly strong in the Hemiptera, Lepidoptera, Coleoptera, Collembola, Crustacea, Mollusca, Echinodermata, and Cnidaria. Collecting and curatorial activities, initiated in the 1920s, were maintained throughout the 1980s, resulting in many taxonomically and historically valuable records for the region. From 1990 to 2005, the invertebrate collections were increasingly neglected, with certain parts scattered throughout multiple buildings and rooms, inaccessible, or inadequately stored and at risk of becoming damaged or lost. The support for these collections was not sustained at high levels due to a variety of factors, including changes in the research profile of new academic appointments and the shortsightedness of administrators to fully understand the cultural, educational and scientific value of the museum holdings. With the exception of a federal grant through NSF - DBI (National Science Foundation - Biological Research Collections - PI Frantz - 2007-2010), which initiated a flurry of Museum related activities to improve the deteriorating museum facilities throughout the UPRM campus, the Museum collections are now facing even more challenges, some anthropogenic and very recently, some natural. Major Hurricane Maria (Category 4), delivered a devastating blow to the island of Puerto Rico on 20 September 2017. Both terrestrial and marine ecosystems were heavily impacted. Extensive structural damage to roads, telecommunications, water systems, the energy grid and approximately 60,000 houses/buildings made Hurricane Maria the most damaging Hurricane (estimated cost ~ 90 billion dollars) in the USA after Katrina and Harvey. Flooding caused by the direct impact of Hurricane Maria (5 to 40 inches of rain fell during the first 48 hours in Puerto Rico) and subsequent extensive loss of electricity caused unfavorable conditions for the collections. The University of Puerto Rico in Mayaguez closed for approximately 45 days and limited electricity, if any, was available through diesel generators. High levels of humidity and heat can cause further structural damage as well as favor the growth of fungus in enclosed areas of UPRM, including the Museums. Efforts to safeguard the collections will be outlined here to ensure the collections remain a valuable natural asset of the people of Puerto Rico as part of their natural patrimony and as an irreplaceable education tool.

Full textAbstract:
In 2005, symptoms of watermelon vine decline (WVD) were observed on a 200-acre watermelon farm in Santa Isabel, on the south central coast of Puerto Rico. WVD symptoms included leaf curling, mosaics, and internode necrosis. In early growth stages of WVD, reduced vigor and plant stunting occurred. At flowering, symptoms progressed to necrosis and wilting of vines. A 2006 to 2007 survey demonstrated that fungal pathogens were not associated with the presence of WVD symptoms (3,4). By 2006, other watermelon fields were also affected. Field trials in 2007 and 2008 with insect-proof cages and insecticides suggested a role of whiteflies (Bemisia tabaci) in the transmission of a virus (3,4). Here, we report that watermelon and pumpkin plants were successfully infected in Puerto Rico by mechanical inoculation and through B. tabaci transmission assays, similarly to transmissions previously conducted in Florida with Squash vein yellowing virus (SqVYV) (1). In addition, plants of Cucurbita moschata exhibited vein clearing symptoms typical of SqVYV after mechanical inoculation with extracts from watermelon plants with WVD symptoms. In 2011, eight watermelon samples from plants exhibiting WVD syndrome were collected in Guánica, Santa Isabel, Juana Díaz, and Mayagüez, and two Momordica charantia samples were collected from Mayagüez. RNA was extracted from all 10 original samples, as well as from plants that were used in mechanical and vector transmission assays, using RNeasy Plant Mini Kit (Qiagen, Valencia, California), and all samples were found positive for SqVYV by reverse transcription-PCR, using previously described primers and methods (1,2). In all cases, a single ~1-kb PCR fragment was revealed, and PCR fragments from four samples were selected for direct sequencing. All sequences showed high levels (>99%) of nucleotide identity with SqVYV sequences from Florida (JF897989, JF897985, and JF897984). Sequences of the SqVYV CP gene from Puerto Rico were deposited in GenBank under accession numbers KC713961 to KC713964. To our knowledge, this is the first report of SqVYV in Puerto Rico associated with WVD syndrome in cucurbits, and thus has implications for management of viral diseases of watermelon in the Caribbean. This is also the first detection of SqVYV outside of the continental United States in both watermelon and a wild species, M. charantia (bitter gourd). References: (1) S. Adkins et al.

Full textAbstract:
Rather than negotiate first with protesting and then striking students, the administration of the University of Puerto Rico (UPR) shut down its flagship Río Piedras Campus from 21 April to 6 July 2010. Regular academic activity on the campus came to a standstill, and as a consequence the semester programmed to end in mid-May could not be finished until mid-August. Yet in those seventy-plus days of closure (cierre) a poignantly expressive culture of resistance took shape out of the continuous tension among the striking students who occupied the campus, the remote administration that refused to respond to their issues, the heavily armed state police officers who were stationed just outside the campus's gates, and the crowds of professors, nonteaching personnel, parents, and student supporters who gathered daily to urge the administration to open a dialogue with the students. Along with independent radio broadcasts, the skillful use of cyberspace, celebrity concerts, and other strategies to capture public and media attention, the protest movement also fostered the spectacle of mass rallies and marches that featured acts of performance and theatre. If the university's theatres were dark, the streets that surround the campus became the stages for seminude, placard-carrying bodies moving serpentine through crowds; stilt-walking masked portrayals of local politicians and university administrators; large, painted-cardboard dragons and wolf heads to stare down police officers; a twenty-foot-tall puppet whose shirt front read “the university is not for sale” (“La UPR no se vende”); processions of black coffins accompanied by black-clad lloronas (mourners); and red-nosed, broom-carrying clowns decked out in tactical police gear to parade comically in front of the heavily armed and real tactical forces.

Full textAbstract:
A new peppermint shrimp species, Lysmata jundalini sp. nov., is described based on five specimens collected in shallowsubtidal waters on Enrique Reef at the University of Puerto Rico, Mayagüez Isla, Magueyes Laboratories. Lysmata jund-alini sp. nov. was identified from fresh material collected at the reef crest and back reef among coral rubble in June 2005and April 2009. The new species is most closely related to the Atlantic Lysmata intermedia and eastern Pacific L. holthu-isi. It can be readily distinguished from all those in the genus Lysmata by its color pattern, the presence of a well developedaccessory branch, the number of free vs. fused segments of the accessory branch, the number of carpal segments of the second pereiopod and well developed pterygostomian tooth.

Full textAbstract:
Background Conservation of tropical freshwater fauna requires a solid understanding of species biodiversity patterns. We provide an up to date annotated list of Odonata of Puerto Rico, which is based on current reports. The list is complemented with notes on the geographic and altitudinal distribution of this order on the island. We also compare current composition relative to early reports conducted when Puerto Rico was mostly an agricultural region. Methods We surveyed adult Odonata all over Puerto Rico with the aid of undergraduate students. Students were trained on capturing, preserving, and data basing specimens. All material was centralized, identified by the lead author, and deposited in the Zoology Museum at the University of Puerto Rico (MZUPR), Río Piedras campus. Surveys were complemented with focal collections by the authors and a literature review of published records for Puerto Rico and the Caribbean. We requested records from specialists to obtain the most complete list of species for the island. Results An annotated list of Odonata from Puerto Rico is presented, reporting 49 species distributed in two suborders and four families. We provide information on species distribution among municipalities and elevations around Puerto Rico. A historic list of species was developed for the 1930s-1940s, when agriculture covered most of Puerto Rico, based on literature and museum specimens. Both current and historic records are similar and suggest that the Odonata fauna is dominated by generalist species and has changed little since the agricultural period. Our list provides a point of reference to understand biodiversity patterns in Puerto Rico and the Caribbean and for assessing the effects of land use change on aquatic insect diversity.

ABSTRACTThere is a need to expand the fundamental skills in science and engineering to include innovation & entrepreneurship (I&E) skills as core competencies. To better prepare the future Nanotechnology workforce, the University of Puerto Rico-Mayagüez Nanotechnology Center, broadened the educational content beyond traditional skills in science and engineering. The Center, offers a rich educational program for materials and nano scientists that aims to create the next generation of knowledgeable, experienced professionals, and successful entrepreneurs, who can develop value-added innovations that can spur economic growth and continue to impact the quality of life for society. Within the educational program an Entrepreneurship Education Co-Curricular Program (EEP) incorporates I&E training into the Materials Science, Nanotechnology, STEM (Science, Technology, Engineering, and Mathematics) faculty and student experiences. The EEP consists of a two-year series of workshops that seek to develop an entrepreneurial mindset, including five key topics: 1) Generation of Ideas, 2) Entrepreneurial Vision, 3) Early Assessment of Ideas, 4) Identification of Opportunities, and 5) Strategic Thinking. The EEP goals, target audience, and implementation strategy, is described with an evaluation tool to assess the program’s success in developing an entrepreneurial mindset.

Full textAbstract:
Purpose On December 14, 2010, University of Puerto Rico (UPR) student activists initiated the second wave of their strike at a disadvantage. The presence of the police force inside the campus raised the stakes for the student movement. No longer did student activists have the “legal rights” or control of the university as a physical public space to hold their assemblies and coordinate their different events. As a result, student activists had to improvise and (re)construct their spaces of resistance by using emotional narratives, organizing non-violent civil disobedience acts at public places, fomenting lobbying groups, disseminating online petitions, and developing alternative proposals to the compulsory fee. This second wave continued until March 2011, when it came to a halt after an incident that involved physical harassment to the Chancellor, Ana Guadalupe, during one of the student demonstrations. The paper aims to discuss these issues. Design/methodology/approach Building on Ron Eyerman’s (2005, p. 53) analysis on “the role of emotions in social movements with the aid of performance theory,” the author center this paper on examining student activists’ tactics and strategies in the development and maintenance of their emotional narratives and internet activism. By adapting Joshua Atkinson’s (2010) concept of resistance performance, the author argues that student activists’ resistance performances assisted them in (re)framing their collective identities by (re)constructing spaces of resistance and contention while immersed in violent confrontations with the police. Findings Ever since the establishment of the university as an institution, student activism has played a key role in shaping the political policies and history of many countries; “today, student actions continue to have direct effects on educational institutions and on national and international politics” (Edelman, 2001, p. 3). Consequently, and especially in times of economic and political crisis, student activism has occupied and constructed spaces of resistance and contention to protest and reveal the existing repressions of neoliberal governments serving as a (re)emergence of an international social movement to guarantee the accessibility to a public higher education of excellence. Thus, it is important to remember that the 2010-2011 UPR student activism’s success should not be measured by the sum of demands granted, but rather by the sense of community achieved and the establishment of social networks that have continued to create resistance and change in the island. Originality/value As of yet there is no thorough published analysis of the 2010-2011 UPR student strike, its implications, and how the university community currently perceives it. By elaborating on the concept of resistance performance, the author’s study illustrates how both traditional and alternative media (re)presentations of student activism can develop, maintain, adjust, or change the students’ collective identity(ies). The author’s work not only makes Puerto Rico visible in the research concerning social movements, student activism, and internet activism; in addition, it provides resistance performance as a concept to describe various degrees of participation in current social movements.

OBJECTIVES/SPECIFIC AIMS: Island communities face greater environmental risks creating challenges in their populations. A community and participatory qualitative research method aiming to understand community perspectives regarding the ecology and environmental risks of the island of Culebra was performed to develop a community-centered Information and Communications Technology (ICT) intervention (an app). The island of Culebra, a municipality from the archipelago of Puerto Rico is located 17 miles from the eastern coast of Puerto Rico’s main island. This ICT—termed mZAP (Zonas, Acción & Protección)—is part of a Translational Biomedical doctoral degree dissertation housed at the University of Rochester’s Clinical Translational Science Institute (CTSI) Informatics Core funded by an NIH Clinical Translational Science Award (CTSA). In September 2017, the island of Culebra faced 2 major category hurricanes 2 weeks apart. Hurricane Irma and Hurricane Maria devastated homes, schools, health clinics, and local businesses, disrupting an already-fragile ecological balance on the island. METHODS/STUDY POPULATION: These 2 storms catastrophically affected the archipelago of Puerto Rico. Culebra’s geographically isolated location, along with the inefficient response from authorities, exacerbated the stressors caused by these natural disasters, increasing the gap of social determinants of health, including the lack of potable water. Leveraging a community engagement partnership established before the hurricanes by the mZAP participatory research, which naturally halted once the hurricanes hit a new humanitarian objective formed to deliver aid. Along with another NIH funded RCMI Translational Research Network, or RTRN institution (University of Puerto Rico, Medical Science Campus) students and faculty, The Puerto Rico Testsite for Exploring Contamination Threats Program (PROTECT) an NIEHS Funded Grant, and the National Guard, a “people to people” approach was established to ascertain needs and an opportunity to meet those needs. A people-to-people approach brings humanitarian needs, identified directly by the community to the people who need it most; without intermediaries and bureaucratic delays that typically occur during catastrophes. RESULTS/ANTICIPATED RESULTS: The consumption of potable water in plastic bottles and subsequent accumulation of plastic material has proven to be collateral damage of a vulnerable water distribution system creating another environmental hazard on the island of Culebra. Therefore, this humanitarian partnership, worked to delivered community and family sized water filters, providing a safe environmental alternative to drinkable water for the island. The success of this approach, People to People for Puerto Rico (#p2p4PUR), demonstrated the power of genuine community engagement—arising from a previous clinical research partnership—and true established commitment with members of the community. DISCUSSION/SIGNIFICANCE OF IMPACT: Research partnerships can (and should, when needed) lead to humanitarian partnerships that extend beyond research objectives. Research may subsequently be adapted based on new realities associated with natural disasters and the altered nature of existing partnerships, allowing for a rapid response to communities need. Further, #p2p4PUR was not only able to channel a partnership humanitarian response but also created an opportunity to reflect on how the commitment between members of society and academia (researchers) can create beneficial bilateral relationships, always putting the community needs first. The resulting shared experience elevates community interest and engagement with researchers, and helps researchers see communities as true partners, rather than—simply—research subjects.

All nutrients were log transformed and adjusted for energy intake. Statistical analyses included correlations, paired t tests, cross-classification and Bland–Altman plots.SettingMedical Sciences Campus, University of Puerto Rico.SubjectsConvenience sample of students, employees and faculty members (n 100, ≥21 years). Data were collected in 2010.ResultsA total of ninety-two participants completed the study. Most were young overweight females. All nutrients were significantly correlated between the two FFQ, with an average correlation of 0·61 (range 0·43–0·73) and an average difference of 4·8 % between them. Most energy-adjusted nutrients showed significant correlations between the FFQ and food record, which improved with de-attenuation and averaged 0·38 (range 0·11–0·63). The lowest non-significant correlations (≤0·20) were for trans-fat, n 3 fatty acids, thiamin and vitamin E. Intakes assessed by the FFQ were higher than those from the food record by a mean of 19 % (range 4–44 %). Bland–Altman plots showed that there was a systematic trend towards higher estimates with the FFQ, particularly for energy, carbohydrate and Ca. Most participants were correctly classified into the same or adjacent quintile (average 66 %) by both methods with only 3 % gross misclassification.ConclusionsThis semi-quantitative FFQ is a tool that offers relatively valid and reproducible estimates of energy and certain nutrients in this group of mostly female Puerto Ricans.

Abstract Hemoglobin S is the most common abnormal hemoglobin detected in newborn screening in Puerto Rico. The purpose of this report is to present laboratory and clinical data from a newborn proven to have combined heterozygocity for hemoglobin S and a very rare hemoglobin. Abnormal newborn screening results using isoelectric focusing prompted us to further study an infant with an unknown hemoglobin. Testing with cellulose acetate and citrate agar electrophoresis revealed that this patient had, besides hemoglobin S, a rare fast moving band. We consulted the Haemoglobinopathy Screening Service at St. James’s University Hospital in Leeds, UK where our patient’s hemoglobin was identified as hemoglobin Porto Alegre by means of mass spectrometry. DNA sequencing at the molecular genetics laboratory in the Medical Sciences Campus, University of Puerto Rico confirmed our patient’s hemoglobin to be Hb Porto Alegre. The patient’s father was found to be heterozygous for hemoglobin S and her mother a carrier of hemoglobin Porto Alegre. Our patient has been followed-up for the last two years. She has remained asymptomatic, except for usual mild childhood diseases. Laboratory results up to 18 months of age have revealed Hgb 11.4–11.6 g/dl, MCV 87.5 fl, MCH 28.7 pg, reticulocyte count 2%, normal total bilirubin and LDH levels. Hemoglobin Porto Alegre involves a mutation in ß9(A6)Ser→Cys which promotes hemoglobin polymerization via disulfide bonds (Baudin-Creuza 2002). This mutation does not seem to alter hemoglobin function and apparently does not increase tendency for sickling. Tondo (1963) has reported that in vivo hemoglobin Porto Alegre exists in its normal tetrameric form, with no associated hemolysis. Martinez (1977) has suggested that hemoglobin Porto Alegre can exist in its tetrameric functional form by means of high levels of glutathione in red blood cells. Therefore, patients with combined hemoglobin S and Porto Alegre would be expected to be asymptomatic. Hemoglobin Porto Alegre has been documented in a few patients from Brazil, Portugal, Argentina, Cuba, and the Canary Islands. To our knowledge this is the first reported double heterozygote for hemoglobin S and Porto Alegre. We are following our patient closely for the development of any significant hematologic or clinical symptoms.

Full textAbstract:
A structural evaluation and analysis of instrumented plain portland cement concrete pavement was performed in a rural primary highway subjected to heavy dynamic loads. Two full-scale slabs were constructed and tested to verify the dynamic analysis of the computer program UPR-PAVI2, which was developed at the University of Puerto Rico at Mayagüez using finite elements. It has the capability to analyze the effect of temperature differential, dead load, and dynamic and static trucks on rigid pavements. UPR-PAVI2 can consider different soil stiffness under the slab, the slab geometry, and multiple trucks and their longitudinal paths, velocities, stiffnesses, geometries, and load distributions. The instrumented slabs included both doweled and undoweled. Their material properties were obtained through laboratory and field tests. The subbase course consisted of a cut section in limestone bedrock for the doweled slab and borrowed material from limestone rock for the fill section used in the undoweled slab. The base course was composed of two layers of nonerodable black bituminous base. The slabs were constructed with concrete with a compressive strength of 34 MPa (5,000 psi) at 28 days. A loaded truck generated the established repetitions by moving over the instrumented slabs at different velocities, producing static and dynamic deflections that were measured with a data acquisition system. The replication and behavior of the response were analyzed, and the validated data were compared with the response obtained using UPR-PAVI2. The results obtained from this simulation were in good agreement with the field data.

Abstract In 2020, on-line courses in Spanish (SP) for dairy (D) and meat (M) goat producers were unveiled (http://certification.goats.langston.edu). These courses complemented the existing courses in English (EN) for D and M. Thirty-one undergraduate and one graduate animal science students at the University of Puerto Rico (UPR), Mayagüez enrolled in the SP courses for beta-testing. Nineteen students completed D-SP, 9 completed M-SP, and 4 completed both. Participants take a pre-test (PRE) and if the PRE score < 85%, a post-test (POST) is required. To complete D, passing scores are required on 18 required modules and 7 of 10 electives. To complete M, passing scores are required on 21 required modules and 9 of 12 electives. A random sample of previous participants (23 D-EN and 13 M-EN) in the same time length (86 ± 18.2 d) was added to the UPR dataset. The objective of this study is to evaluate the difference (DIFF) between PRE and POST scores as a measure of knowledge transfer. Mixed model analysis was conducted with the dependent variable of DIFF, the independent variables of course (D or M), language (EN or SP), the two-way interaction, and participant as the random effect. There were significant course (P > 0.01) and language (P > 0.05) effects on DIFF. M had lower DIFF than D (29.0% vs 34.1%) and EN had lower DIFF than SP (29.2% vs 34.0%). When required module within course (18 for D and 21 for M) was added to the model to examine specific module differences, there was a significant course(module)*language interaction (P > 0.01) with values ranging from 15.6% for Preventive Herd Health in EN M to 45.1% for Milking Systems in SP D. Participant background and language may play a role in knowledge transfer for online courses; however, a larger sample would be needed to confirm this hypothesis.

OBJECTIVES/GOALS: To assess the impact of FLTCs on CTR on S and F from health professions and basic science academic programs island wide in Puerto Rico. Cycles supported by the Title V Cooperative Project at University of Puerto Rico-Medical Sciences Campus (UPRMSC) and Universidad Central del Caribe (UCC)(Title V). METHODS/STUDY POPULATION: After offering FLTCs in CTR to S and F from UPRMSC and UCC, Title V expanded it to S and F from other institutions island wide in PR. These FLTCs were offered the 2nd semester of 2018 and consisted of 20 hours of interdisciplinary sessions in: introduction to and definition of CTR; preparation of a CTR-presentation; how to interview/share a presentation of a CT researcher and to prepare a research question in CTR. To assess the knowledge of S and F in the above-mentioned skills and their continuation in the 2nd level of CTR training, surveys were administered: pre-test, at the beginning, post-test, sometime during the FLTCs, and satisfaction at the end of the FLTCs. RESULTS/ANTICIPATED RESULTS: Fifty eight (58) S/F from UPRMSC, UCC and 7 other institutions participated. Forty two (42,72%) answered a pre-test and 31/42 (74%) completed the post-test. Results showed that S/F: who correctly defined CTR increased from 7% to 77 %; their ability to identify a CT researcher increased from 10% to 83%. Fifty five percent (55 %) (21/38) S/F that were certified in the FLTCs, answered the satisfaction survey. One hundred percent (100%) indicated that the materials offered contributed in the identification of a CT researcher and a topic in CTR; 100% answered that the FLTCs contributed higher knowledge in and provided new skills in CTR. Moreover, 31/38 (82%) S/F started the 2nd level of training. DISCUSSION/SIGNIFICANCE OF IMPACT: The FLTCs were successful in increasing S/F knowledge of CTR and to further engage in 2nd level of trainings. Title V impact extended island wide, increasing the diversity of represented health professions and science fields among participants. The interventions were deemed to be of high quality.

OBJECTIVES/SPECIFIC AIMS: Patients with epilepsy often combine their antiepileptic drugs (AEDs) with complementary medicine (CM). They use CM to treat their symptoms of comorbidities disorder, to reduce the side effect of the AEDs or trying to achieve better control of their seizures. However, the inconsistent patters of the use of CM among countries have been attributed to cultural and socio-economic factors and limited studies have explored biological factors. The aim of this study is to determinate whether or not there is an association between having genetic polymorphisms on candidate pharmacogenes for drug-metabolizing enzymes cytochrome P450 (CYP) and the use CM among patients with drug-resistant epilepsy (DRE). METHODS/STUDY POPULATION: In this cross-sectional study, patients will be recruited in the Epilepsy Clinic in the Medical Science Campus of University of Puerto Rico and in private Neurology clinics. To participate in this study, patients need to have both parents of Puerto Rican origin to be defined as Puerto Rican and have a diagnosis of DRE, defined as persistent seizures after at least 2 good trials of the proper drugs at the right dose. After the patient sign, the inform consent, a buccal swap will be collected, and the patient will complete a questionnaire. In the questionnaire, the patient will do a self-report about the use of CM (including natural products, meditation, yoga, and others), frequency of use and socio-economic information. Polymorphisms for CYP 2D6, 2C9, 2C19, or 1A2 will be determined using TaqMan® SNP Genotyping Assays. Data analysis will include descriptive statistical, χ2 and ANOVA test. RESULTS/ANTICIPATED RESULTS: We expected to determine the frequency distribution of functional polymorphisms on CYPs among patients with DRE who are either using CM and AEDs or standard care (AEDs). Quantified the use of CM and ascertain if there is an association with the CYPs polymorphisms. DISCUSSION/SIGNIFICANCE OF IMPACT: This study is novel, because we will use an objective test, pharmacogenetics approach to rule out biological factors associated with the use of Complementary Medicine by patients’ DRE. The study will provide evidence for prospective study using specifics Complementary Medicine guiding by genotyping.

OBJECTIVES/SPECIFIC AIMS: The University of Puerto Rico-Medical Sciences Campus and Universidad Central del Caribe, through the Title V Cooperative Project, devised a clinical and translational research (CTR) platform to pipeline students/faculty of undergraduate health sciences programs into CTR. Educational interventions in CTR—introductory intervention (II) and Annual Symposium (AS)—were designed to promote awareness, stimulate interest of students and faculty in CTR. METHODS/STUDY POPULATION: In the II the participants (n=159) were surveyed before and after a presentation and panel discussion about CTR. In addition, after the sessions—plenary, panel, and workshop—about CTR, the participants of AS (n=42) were surveyed for satisfaction and learning experience in CTR. RESULTS/ANTICIPATED RESULTS: Most participants of the II, 134 (84.3%) were students. In total, 58 (58, 36.5%) completed the post II survey. Of these, 53.4% satisfactorily defined the CTR concept Versus only 31.0% that could define CTR in the pre survey, 47 (81.7%) were unable to identify a CTR researcher and 45 (78.3 %) expressed interest in learning about CTR. In total, 28 (28, 66.7%) participants of the AS completed the satisfaction survey, out of which 17 (60.6%) were students. One hundred percent (100%) agreed that the AS served as a vehicle to increase their knowledge in CTR. DISCUSSION/SIGNIFICANCE OF IMPACT: The educational interventions demonstrated to be an effective strategy to promote awareness and stimulate interest of students and faculty in CTR. In addition, the results obtained, provided valuable baseline information for the planning—development of training cycles in CTR.

OBJECTIVES/SPECIFIC AIMS: The objective of the present study is to determine if decreased adiponectin and increased leptin levels are associated with the development of MetS and identifiable endothelial dysfunction in a cohort of Hispanic pre-pubertal children. To do so we propose the following aims: (1) To measure expression of adiponectin and leptin levels in a Hispanic pre-pubertal cohort and determine their correlation with features of the MetS. (2) To perform proteomic analysis in a Hispanic pre-pubertal cohort. (3) Evaluate early onset of endothelial dysfunction and its correlation with expression of adiponectin and leptin levels in a Hispanic pre-pubertal cohort. METHODS/STUDY POPULATION: A cross-sectional pilot study will obtain a random representative sampling of children aged 6–12 years from all geographical areas of Puerto Rico. Children will be assessed regarding pre-pubertal status through Tanner staging and later divided into pre-MetS Versus MetS groups as well as controls. MetS will include children meeting 3 or more of the current International Diabetes Federation (IDF) criteria. Pre-MetS will include children with at least 1 criterion for MetS. Anthropometric data, blood pressure readings, ultrasound-based noninvasive testing for endothelial dysfunction, and laboratory assays will be performed to the study population and data analyzed for correlation. Total adiponectin and leptin levels will be measured using a commercially available quantitative sandwich enzyme-linked immunoassay test. The study will be submitted to the University of Puerto Rico Medical Sciences Campus’ Institutional Review Board (IRB) for approval. Written consent and assent will be obtained from parents and children respectively to ensure patient anonymity. RESULTS/ANTICIPATED RESULTS: We hypothesize that low levels of adiponectin and high levels of leptin will correlate with features of the MetS as defined by the IDF consensus statement, as well as with clinical features of MetS in undiagnosed Hispanic pre-pubertal youth. We also hypothesize that non-invasive testing of endothelial function will correlate both with clinical features of the MetS and with low levels of adinopectin and high levels of leptin. DISCUSSION/SIGNIFICANCE OF IMPACT: The correlation of findings suggestive of endothelial dysfunction and biomarker expression (mainly adiponectin and leptin levels) in a pre-pubertal cohort has yet to be established and could also provide information regarding early atherogenesis in otherwise unidentified youth at risk. Therefore, by using a proteomic approach, this study aims to measure associations between clinical features of the MetS and expression of proteins associated with an adverse cardiometabolic profile in a Hispanic pre-pubertal population. We will concurrently measure the degree of endothelial dysfunction and evaluate whether a correlation exists between previously mentioned protein expression and early onset of dysfunction.

IntroductionMinority populations in the USA are disproportionately affected by cardiovascular conditions. Reduced responsiveness to clopidogrel among carriers of CYP2C19 variants has been reported in patients with either coronary artery disease (CAD) or acute coronary syndrome (ACS) after the percutaneous coronary intervention (PCI). Previous studies have evaluated CYP2C19 genotyping-guided antiplatelet therapy in selected populations; however, this has yet to be tested among Hispanics. Given the paucity of clinical research on CYP2C19 and antiplatelet clinical outcomes in Hispanics, our study will test the safety and efficacy of a genetic-driven treatment algorithm to guide dual antiplatelet therapy (DAPT) in Caribbean Hispanics.Methods and analysisThis is a multicentre, prospective, non-randomised clinical trial that proposes an assessment of pharmacogenomic-guided DAPT in post-PCI Caribbean Hispanic patients with ACS or CAD. We will recruit 250 patients to be compared with a matched non-concurrent cohort of 250 clopidogrel-treated patients (standard-of-care). Major adverse cardiovascular events (MACEs) such as all-cause death, myocardial infarction (MI), stroke, coronary revascularisation, stent thrombosis and bleedings over 6 months will be the study endpoints. Among the recruited, high-risk patients will be escalated to ticagrelor and low-risk patients will remain on clopidogrel. The primary objective is to determine whether genetic-guided therapy is superior to standard of care. The secondary objective will determine if clopidogrel treatment in low-risk patients is not associated with a higher rate of MACEs compared with escalated antiplatelet therapy in high-risk patients. Patients will be enrolled up to the group’s completion.Ethics and disseminationApproval was obtained from the Institutional Review Board of the University of Puerto Rico Medical Sciences Campus (protocol # A4070417). The study will be carried out in compliance with the Declaration of Helsinki and International Conference on Harmonization Good Clinical Practice Guidelines. Findings will be published in a peer-reviewed journal and controlled access to experimental data will be available.Trial registration numberNCT03419325; Pre-results.

This study aimed to explore the perceived barriers to physical activity among college students Study Design: Qualitative research design Eight focus group discussions on 67 college students aged 18-24 years (48 females, 19 males) was conducted on College premises. Data were analysed using inductive approach. Participants identified a number of obstacles to physical activity. Perceived barriers emerged from the analysis of the data addressed the different dimensions of the socio-ecological framework. The result indicated that the young adults perceived substantial amount of personal, social and environmental factors as barriers such as time constraint, tiredness, stress, family control, safety issues and much more. Understanding the barriers and overcoming the barriers at this stage will be valuable. Health professionals and researchers can use this information to design and implement interventions, strategies and policies to promote the participation in physical activity. This further can help the students to deal with those barriers and can help to instil the habit of regular physical activity in the later adult years.

ABSTRACTSince 2005, the University of Puerto Rico-Mayagüez (UPRM) has co-facilitated materials science and engineering (MSE) clubs at low-income middle and high schools in Western Puerto Rico to increase awareness and interest in the areas of materials science, nanotechnology, and engineering. In this article, we describe the club activities and share the results of the 2009 end-of-year assessment regarding knowledge, interest, and educational aspirations in MSE, along with differences based on gender, parent education level, and school level. Overall, participants expressed positive opinions about engineering as a career. While students expressed high interest in pursuing university studies in science and engineering, some differences became apparent based on gender, parent education level, and school level. There were also differences between boys and girls in perceived knowledge gains. The results of this assessment provide promising evidence that school-based MSE clubs may help attract underserved students into the MSE pipeline.

Frontiers in Sustainable Food Systems 5 (July 5, 2021). http://dx.doi.org/10.3389/fsufs.2021.662918.
Full textAbstract:
Farmers across the globe are experiencing compounding shocks that make evident the need to better understand potential drivers and barriers to strengthen adaptive capacity. This is especially true in the context of a disaster, where a disruption in the natural and built environment hinders livelihood strategies and exposes the underlying dynamics that perpetuate vulnerability to natural hazards. As such, the interconnections of structural and individual attributes must be considered when evaluating adaptive capacity. This paper uses a convergent mixed-methods approach to assess Puerto Rican farmers' actual and intended adoption of adaptation practices, in light of the obstacles they faced toward recovery after 2017's category four Hurricane Maria, to contribute to better understanding adaptive capacity. This study uses data from 405 farmers across Puerto Rico (87% response rate), surveyed 8 months after Maria by agricultural agents of the Extension Service of the University of Puerto Rico at Mayagüez. Quantitative data was assessed through negative binomial regressions (actual adoption) and generalized linear models (intended adoption), while qualitative data (reported obstacles) were analyzed through thematic analysis. This study found that almost half of farmers adopted an adaptation practice after Maria, and that in many cases, broader structures, such as systems of governance, farmers' social networks, and infrastructure, affect adaptive capacity more than individual perceptions of capacity. Future adaptation strategies and interventions, especially in the context of disaster, should consider the extent to which structural factors hinder individuals' ability to prepare for, respond, and recover from the impacts of these shocks. Our results show that there might be opportunity to enact new systems in light of catastrophic events, but this does not solely depend on individual actions. The mixed-methods approach used can inform future studies in better assessing adaptive capacity from a standpoint that incorporates individual and structural components.

Full textAbstract:
University Social Responsibility (USR) is the ethical and transparent management of the administrative, educational, cognitive and social processes carried out by a higher education institution. More and more universities are practicing USR not only in Latin America but also in the United States and Europe, in order to reduce the negative impacts their daily operations can have on different stakeholders and on a macro level on society, the economy, and the environment. However, despite existing knowledge in the implementation of USR in Latin America and the Caribbean, there are few empirical studies that analyze the positions of diverse internal stakeholders regarding USR practices mainly in the Caribbean. Therefore, this study analyzes the perspectives of the internal stakeholders in social responsibility initiatives and processes at a private university in Puerto Rico. A total of 533 participants (356 students, 99 administrative staff, and 78 faculty members) were interviewed and were given a questionnaire, which evaluated the following areas: responsible campus, professional and citizenship education, social knowledge management, and social participation. Overall, the internal stakeholders’ perceptions were consistent among the three groups. It can be observed that the various internal stakeholders are aware of what it means—in theory, and in practice—, to be a socially-responsible university, although they also recognize opportunities for improvement and future challenges regarding USR. The results of this study contribute to the literature, to the application of conceptual models—mainly from the perspectives of internal stakeholders—and to the importance of evaluating USR practices.
