Abstract
Background After percutaneous coronary intervention (PCI), clopidogrel resistant patients are at an increased risk of major adverse cardiovascular and cerebrovascular events (MACCEs). We aimed to assess whether genotype-guided selection of oral antiplatelet drugs using a clinical decision support (CDS) algorithm reduces the occurrence of these ischemic events and improves outcomes among Caribbean Hispanic patients from Puerto Rico, who are underrepresented in clinical pharmacogenomic (PGx)-guided implementation studies. Methods Individual platelet function testing (PRU) measures, CYP2C19*2 and PON1 rs662 genotypes, clinical and demographic data from 8 medical facilities were included. Patients were separated into standard of care (SoC) and genotype-guided groups (150 each). Risk scores were calculated based on a previously developed CDS risk prediction algorithm designed to make actionable treatment recommendations for each patient. Alternative therapy with ticagrelor was recommended for patients with a high risk score ≥2. Statistical associations between patient time free of MACCEs and predictor variables (i.e., treatment groups, risk scores) were tested in this population using Kaplan-Meier survival analyses and Cox proportional-hazards regression models. Results Median age of participants is 67 years; BMI: 27.8; 48% women; 14% smokers; 59% with type-2 diabetes mellitus (T2DM). Among patients with high-risk scores who were free from MACCE events 6 months after coronary stenting, genotype-driven guidance of antiplatelet therapy showed superiority over SoC in terms of reducing the incidence rate of atherothrombotic events. Conclusions The clinical utility of our PGx-driven CDS algorithm to reduce the incidence rate of MACCEs among post-PCI Caribbean Hispanic patients on clopidogrel was externally demonstrated. Clinical Trial Registration Unique Identifier NCT03419325.

Abstract
OBJECTIVE The primary aim of this cross-sectional study was to assess, according to previous cancer diagnosis, the knowledge Puerto Rican women have on the link between obesity-endometrial, -breast, and colon cancer, and determine women's most common source for medical information. METHODS In this cross-sectional study, eligible female patients (n=234) from the Gynecology and Gynecology-Oncology Clinics completed a self-administered survey from October 2014 to March 2016. Participants were evaluated on sociodemographic, body mass index, knowledge of the obesity-cancer link, and source of medical information. RESULTS About 49% and 31% of women in the study were obese and overweight, respectively. Less than 52% of the women knew about the link between obesity-breast,-colon, and/or -endometrial cancers. Women with previous cancer diagnoses were more likely aware of the association between obesity-colon cancer than women without previous cancer diagnoses (58% vs. 44%, p0.05). Higher incomes showed increased odds for the knowledge obesity-cancer link among women with a cancer history, but the odds decreased for women without previous cancer diagnoses (p>0.05). Higher education showed a trend towards a better knowledge of the obesity-cancer association. The most common sources of information were the primary doctor (80%) and the internet (54%). CONCLUSION Counseling about preventable cancer risk factors through primary care to all women must be encouraged especially in young healthy females. Further studies should address qualitative aspects of the odds differences in the obesity-cancer link knowledge observed between income categories for women with/without previous cancer diagnoses.

Abstract
OBJECTIVE Influenza affects 5-15% of the worldwide population and is responsible for 4-5 million cases and 250,000-500,000 deaths. Despite established recommendations, vaccination rates continue to be low. Our study aimed to identify barriers to influenza immunization and attitudes toward the vaccine among respiratory health care (HC) professionals in Puerto Rico. METHODS We conducted an anonymous written survey that was handed out to 130 HC professionals, including physicians, nurses and respiratory therapists, who attended the Annual Respiratory Disease Congress held in San Juan, Puerto Rico, on August 2018. RESULTS A total of 68 health care professionals participated in the study. Nearly 34% of participants reported never receiving influenza immunization themselves, 13% reported intermittent immunization, and 53% received immunizations yearly. Approximately 82% and 87% of the participants believed the influenza vaccine to be safe and effective, respectively. Sixty- five percent of respiratory therapists considered the vaccine effective, as compared to 94% of physicians and 100% of nurses and other HC professionals (p=0.023). Most of the participants (87%) recommended influenza immunization, although 38% of participants indicated being concerned about potential side effects of the vaccine. Knowledge of current clinical indications for influenza immunization for medical conditions varied from 59% for patients on systemic steroids to 94% for patients with diabetes mellitus. CONCLUSION This survey among respiratory HC professionals in Puerto Rico demonstrated barriers in knowledge about vaccination, its indications, and its safety. Addressing these barriers provides us with opportunities to improve influenza immunizations rates among HC workers and their patients.

Abstract
OBJECTIVE This was a cross-sectional study associating vitamin D, calcium, magnesium, and potassium intakes with markers of glucose metabolism in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). METHODS HCHS/SOL is a multicenter, prospective, population-based cohort study on Hispanics/Latinos aged 18-74 years in the US. For this analysis, we included 10,609 participants who were free of diabetes. Analysis of covariance was used to assess associations of a range of micronutrient intake on the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), Hemoglobin A1c (HbA1c), and 2-hour post-oral glucose tolerance test (2h-plasma glucose) separately for normoglycemic and with pre-diabetes, after controlling for important confounders. All analyses accounted for the complex sample design and sampling weights. RESULTS HOMA-IR levels were significantly lower among adults with intakes in the highest quartile for vitamin D, magnesium, and potassium compared to the respective lowest quartiles, for those with normoglycemia and pre-diabetes, even after adjusting for confounders, such as diet quality (p < 0.05). For those with pre-diabetes, HOMA-IR levels were also significantly lower for those in the highest quartile of calcium intake. However, 2h-plasma glucose was significantly higher in those with intakes higher than quartile 1 for vitamin D and calcium among those with normoglycemia and significantly higher in quartile 3 of potassium intake for those with pre-diabetes, p < 0.05. No significant associations were found for HbA1c in either group. CONCLUSIONS Higher consumption of vitamin D, magnesium, and potassium are associated with optimal levels of HOMA-IR among participants with normoglycemia and pre-diabetes.

Abstract
OBJECTIVE Gestational Diabetes Mellitus (GDM) and Type 2 Diabetes Mellitus (DM2) are metabolic disorders characterized by increased insulin resistance. Although insulin is the treatment of choice in pregnant patients with DM, the prescription of oral hypoglycemic agents (OHA) has been increasing among practitioners. This study aimed to evaluate the maternal and neonatal outcomes when oral hypoglycemic agents were used in diabetic pregnant women. METHODS Medical records from the Maternal-Infant Care Unit Clinics SoM-UPR (n=149) were reviewed. Patients that were treated with metformin, sulfonylurea or insulin were included. Maternal and neonatal outcomes were compared between groups. RESULTS Patient's mean age was 28 ± 6 years. The majority had GDM (91%). The most common comorbidity was hypertension (9.9%). Lifestyle modification was used as treatment in 77% of patients during the second trimester, but its use decreased to 33% during the third trimester. Insulin was the treatment of choice. Among the OHA, sulfonylurea was preferred. Postprandial glucose levels were lower in patients who used insulin as compared to those without medications. CONCLUSION No significant differences were found in maternal outcomes such as C-section, induction of labor, episiotomy or preterm labor, or neonatal outcomes such as macrosomia, neonatal hypoglycemia or congenital abnormalities among treatment groups. OHA can be considered as an alternative to insulin for the treatment of DM during pregnancy in selected cases.

Abstract
Objective The American Academy of Ophthalmology recommends a maximum hydroxychloroquine (HCQ) dose of ≤5.0 mg/kg/day to reduce the risk of HCQ-induced retinopathy. To determine if this dose adjustment would have an impact on the clinical course of SLE, we compared outcome measures in a cohort of patients with SLE before and after adjusting HCQ dose. Methods Sixty Puerto Ricans with SLE (per 1997 American College of Rheumatology criteria) treated with HCQ who were changed to HCQ ≤5.0 mg/kg/day were studied. Visits were ascertained every 6 months for 2 years before and 2 years after HCQ dose adjustment (baseline visit). Disease activity (per Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)), SLE exacerbations, emergency room visits, hospitalisations, disease damage (per Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), corticosteroids exposure, prednisone dose and immunosuppressive drugs exposure were determined before and after HCQ dose change. Results At baseline visit, the mean age was 43.8±15.1 years. All patients were women. The mean disease duration was 13.8±9.1 years. After HCQ dose adjustment, patients required a lower prednisone dose when compared with visits before HCQ dose reduction. No significant differences were observed for mean SLEDAI scores, lupus exacerbations, emergency room visits, hospitalisations, disease damage and exposure to immunosuppressive drugs before and after HCQ dose adjustment. Conclusions This study suggests that adjustment of daily HCQ dose to ≤5.0 mg/kg/day of actual body weight does not have a significant impact on the short-term and mid-term outcomes in this group of patients with SLE.

Abstract
OBJECTIVE Our study sought to evaluate how aware the women attending gynecology clinics at the University of Puerto Rico Medical Sciences Campus (UPRMSC) were of the association between infertility and excess body weight (i.e., overweight and obesity). METHODS Women 21 years old and older attending gynecology clinics at UPR-MSC were invited to participate in this study (n = 234). A self-administered survey was provided to all the women. Logistic regression models were performed to determine associations. RESULTS About 56.8% of the women were found to be aware of the effects of obesity on fertility; their main source of medical information was their primary doctor. The odds (adjusted for age and annual income) of being aware of the association between obesity and infertility were about 2.41 (95% CI: 1.07-5.42) times higher in women with a BMI greater than or equal to 25 kg/m2 than they were in those with a BMI of less than 25 kg/m2. An interaction by age group (adjusted for BMI) was found for the association between annual income and knowledge of the obesity-infertility association (OR≥40 years old: 3.51, 95% CI: 1.41-8.72; OR<40 years old: 0.57, 95% CI: 0.15-2.13). CONCLUSION Our study revealed that there is a lack of knowledge regarding the effects of obesity on fertility and identifies characteristics associated with this knowledge. The contents of health-care-provider counseling and the barriers affecting communication between patients and health care providers could be assessed in further studies.

Abstract
Background and Objectives: The cannabinoid receptor 2 (CB2) was previously implicated in brain functions, including complex behaviors. Here, we assessed the role of CB2 in selected swimming behaviors in zebrafish larvae and developed an in vivo upscalable whole-organism approach for CB2 ligand screening. Experimental Approach: Using CRISPR-Cas9 technology, we generated a novel null allele (cnr2upr1) and a stable homozygote-viable loss-of-function (CB2-KO) line. We measured in untreated wild-type and cnr2upr1/upr1 larvae, photo-dependent (swimming) responses (PDR) and center occupancy (CO) to establish quantifiable anxiety-like parameters. Next, we measured PDR alteration and CO variation while exposing wild-type and mutant animals to an anxiolytic drug (valproic acid [VPA]) or to an anxiogenic drug (pentylenetetrazol [PTZ]). Finally, we treated wild-type and mutant larvae with two CB2-specific agonists (JWH-133 and HU-308) and two CB2-specific antagonists, inverse agonists (AM-630 and SR-144528). Results: Untreated CB2-KO showed a different PDR than wild-type larvae as well as a decreased CO. VPA treatments diminished swimming activity in all animals but to a lesser extend in mutants. CO was strongly diminished and even more in mutants. PTZ-induced inverted PDR was significantly stronger in light and weaker in dark periods and the CO lower in PTZ-treated mutants. Finally, two of four tested CB2 ligands had a detectable activity in the assay. Conclusions: We showed that larvae lacking CB2 behave differently in complex behaviors that can be assimilated to anxiety-like behaviors. Mutant larvae responded differently to VPA and PTZ treatments, providing in vivo evidence of CB2 modulating complex behaviors. We also established an upscalable combined genetic/behavioral approach in a whole organism that could be further developed for high-throughput drug discovery platforms.

Abstract
PURPOSE To identify racial/ethnic disparities in utilization rates, in-hospital outcomes and health care resource use among Non-Hispanic Whites (NHW), African Americans (AA) and Hispanics undergoing transcatheter aortic valve replacement (TAVR) in the United States (US). METHODS AND RESULTS The National Inpatient Sample database was queried for patients ≥18 years of age who underwent TAVR from 2012 to 2014. The primary outcome was all-cause in hospital mortality. A total of 36,270 individuals were included in the study. The number of TAVR performed per million population increased in all study groups over the three years [38.8 to 103.8 (NHW); 9.1 to 26.4 (AA) and 9.4 to 18.2 (Hispanics)]. The overall in-hospital mortality was 4.2% for the entire cohort. Race/ethnicity showed no association with in-hospital mortality (P > .05). Though no significant difference were found between AA and NHW in any secondary outcome, being Hispanic was associated with higher incidence of acute myocardial infarction (aOR = 2.02; 95% CI, 1.06-3.85; P = .03), stroke/transient ischemic attack (aOR = 1.81; 95% CI, 1.04-3.14; P = .04), acute kidney injury (aOR = 1.65; 95% CI, 1.23-2.21; P < .01), prolonged length of stay (aOR = 1.18; 95% CI, 1.08-1.29; P < .01) and higher hospital costs (aOR = 1.27; 95% CI, 1.18-1.36; P < .01). CONCLUSION There are significant racial disparities in patients undergoing TAVR in the US. Though in-hospital mortality was not associated with race/ethnicity, Hispanic patients had less TAVR utilization, higher in-hospital complications, prolonged length of stay and increased hospital costs.

Abstract
OBJECTIVE Vitamin D status is primarily dependent upon sun exposure and dietary sources, however genetic, cultural, and environmental factors can have a modulating role in the measured amount. One under-reported factor is the effect of regular living quarters on the degree of sun exposure. Herein, we assess vitamin D status in the blood of Rhesus monkeys (Macaca mulatta) housed in high amounts of sunlight (corn-cribs), medium sunlight (corrals with shaded areas), and minimal sunlight (quarantine cages). METHODS Fifty-five male Rhesus monkeys, aged 1 to 31 years were housed in varying amounts of sun exposure at the Caribbean Primate Research Center. Serum was collected and analyzed for 25 OH Vitamin D which is the preferred metabolite for determination of Vitamin D using High Performance Liquid Chromatography (HPLC). RESULTS 25 OH Vitamin D levels in blood were significantly greater in corn-cribhoused monkeys than in corral or quarantine-housed animals (p > 0.01 and p > 0.001 respectively). Significant differences of serum levels were not found when ages of animals housed in the same environment were compared. CONCLUSION Monkeys housed in a tropical environment with the greatest amount of exposure to sunlight maintain the highest serum levels of 25 OH vitamin D independent of age. These findings emphasize the importance of documenting the environment in which subjects typically spend their time when Vitamin D results are interpreted.

Abstract
Objective Infections are a major cause of morbidity and mortality in systemic lupus erythematosus. Clinical outcomes of systemic lupus erythematosus patients hospitalized due to infections vary among different ethnic populations. Thus, we determined the outcomes and associated factors in a group of Hispanics from Puerto Rico with systemic lupus erythematosus admitted due to severe infections. Methods Records of systemic lupus erythematosus patients admitted to the Adult University Hospital, San Juan, Puerto Rico, from January 2006 to December 2014 were examined. Demographic parameters, lupus manifestations, comorbidities, pharmacologic treatments, inpatient complications, length of stay, readmissions, and mortality were determined. Patients with and without infections were compared using bivariate and multivariate analyses. Results A total of 204 admissions corresponding to 129 systemic lupus erythematosus patients were studied. The mean (standard deviation) age was 34.7 (11.6) years; 90% were women. The main causes for admission were lupus flare (45.1%), infection (44.0%), and initial presentation of systemic lupus erythematosus (6.4%). The most common infections were complicated urinary tract infections (47.0%) and soft tissue infections (42.0%). In the multivariate analysis, patients admitted with infections were more likely to have diabetes mellitus (odds ratio: 4.20, 95% confidence interval: 1.23-14.41), exposure to aspirin prior to hospitalization (odds ratio: 4.04, 95% confidence interval: 1.03-15.80), and higher mortality (odds ratio: 6.00, 95% confidence interval: 1.01-35.68) than those without infection. Conclusion In this population of systemic lupus erythematosus patients, 44% of hospitalizations were due to severe infections. Patients with infections were more likely to have diabetes mellitus and higher mortality. Preventive and control measures of infection could be crucial to improve survival in these patients.

Abstract
Background Numerous studies have demonstrated a strong relationship between circulating levels of marinobufagenin (MBG) and salt-sensitivity. Since salt-sensitive hypertensives have increased plasma levels of MBG and are known to be at a higher risk of having cardiovascular events, stroke and increased mortality, we evaluated the possibility of an association between MBG and ischemic stroke. In this pilot study, we determined plasma MBG levels in patients after surviving an ischemic stroke compared to similar age and gender groups of treated hypertensives and normotensive controls. Methods We measured plasma MBG levels in a total of 40 participants subdivided into three groups: After an ischemic stroke STR (n = 13), participants with a diagnosis of hypertension receiving blood pressure medication HT (n = 14) and normotensive control subjects CTL (n = 13). We used inferential statistics (parametric or non-parametric) and ordered logistic regression models (unadjusted and adjusted) and all statistical analyses were performed using Stata 14. Results We did not include a subject from the CTL group because of a diagnosis of glucose-6-phosphate dehydrogenase deficiency and an extreme plasma MBG value of 2,246 pmol/L. Participants' mean age was 60.4 ± 11.5 years; 56% were male. There was no significant difference between study groups (p > 0.05) for gender, age, and body mass index. HbA1c levels were significantly higher in the STR as compared to the CTL p < 0.05). In the STR group MBG levels were below the normal range (< 200 pmol/L) in three (23%), eight (61%) were in the normal range (200-400 pmol/L), while two (16%) had increased MBG values (> 400 pmol/L). Also, among the STR, the plasma MBG levels did not differ between those receiving and not receiving thrombolytic therapy (p > 0.05). From the 14 HT participants, six (43%) had MBG plasma levels within the normal range, and eight (57%) had high concentrations (> 400 pmol/L). Four (29%) of the treated hypertensives had extreme MBG levels (> 1,000 pmol/L) and normal values of blood pressure. Conclusion There was no significant elevation of plasma MBG in survivors 24 h or more after an ischemic stroke. The extreme values of plasma MBG in 29% of the treated hypertensives suggests the presence of salt-sensitivity and a possible side effect of a specific combination of medications. Both of these findings contribute new knowledge to the design of studies to define if there is an MBG molecular mechanism underlying the complex associations among salt-sensitivity, hypertension, and ischemic stroke.

Abstract
BACKGROUND The conventional treatment for idiopathic intracranial hypertension involves weight loss, steroids, diuretics, and/or serial lumbar punctures; however, if the symptoms persist or worsen, surgical intervention is recommended. Surgical options include cerebrospinal fluid diversion procedures, such as ventriculoperitoneal and lumboperitoneal shunts, and optic nerve decompression with nerve sheath fenestration. The latter can be carried out using an endoscopic approach, but the outcomes of this technique have not been firmly established. METHODS This systematic review examined the outcomes of performing endoscopic optic nerve decompression (EOND) in patients with idiopathic intracranial hypertension (IIH). Six studies were included for a total of 34 patients. RESULTS The patients presented with visual field disturbances (32 of 32 [100%]), visual acuity disruptions (33 of 34 [97.1%]), papilledema (26 of 34 [76.5%]), and persistent headache (30 of 33 [90.1%]). The mean duration of symptoms ranged from 7 to 32 months. Overall, the patients showed post-EOND improvement in signs and symptoms associated with IIH, specifically visual field deficits (93.8%), visual acuity (85.3%), papilledema (81.4%), and headaches (81.8%). Interestingly, 11 cases showed postoperative improvement in their symptoms with bony decompression of the optic canal alone, without nerve sheath fenestration. There were no major adverse events or complications reported with this approach. CONCLUSION EOND appears to be a promising and safe surgical alternative for patients with IIH who fail to respond to medical treatment. Further studies are needed before we can attest to the clinical validity of this procedure.

Abstract
Fungal infections represent a serious complication for immunosuppressed patients resulting in an increased morbidity and mortality. A non-concurrent prospective study was performed to evaluate the factors associated to invasive fungal infection (IFI) in patients with hematological malignancies admitted to the University Hospital in San Juan, Puerto Rico from January 1st, 2011 through June 15th, 2014. The medical records of 84 patients were evaluated. Fifty-nine patients with IFI and twenty-five without IFI. The majority were men between 35 to 55 years old. The main hematological diagnosis was acute myelogenous leukemia (AML) followed by acute lymphoblastic leukemia (ALL). Seventy-percent developed IFI. The most common fungi were C. albicans followed by non-albicans species, Fusarium and, Aspergillus species, respectively. About 63% of the patients with AML and 81% without AML had IFI. Those who received steroids were more likely to develop IFI. After adjusting for AML and age, the odds of IFI among patients using steroids were 3.33 higher than those not using steroids. Patients who were exposed to different antifungal medication had 72% lower odds to develop IFI.

Abstract
OBJECTIVE The purpose of this study was to evaluate the association between measures of patient arrival day (weekday or weekend day), day part (nighttime vs. daytime) and hour (regular hours vs. off hours) at the stroke unit of the Emergency Department of the Puerto Rico Medical Center and the following time-to-treatment measures: door-to-CT-scan, door-to-needle, and stroke-onset-to-treatment. METHODS In this retrospective study, the data of 54 patients was obtained from the stroke unit of the Puerto Rico Medical Center through the Get With The Guidelines- Stroke Registry. Inclusion criteria were as follows: having an ischemic stroke within the period covering from August 2008 through February 2010 and being at least 18 years old. Associations between patient arrival time and timeliness of interventions were assessed using t-tests/Mann-Whitney tests and chi-square tests/Fisher's exact tests, as appropriate. RESULTS The majority of the patients (74%) were men. The mean and standard deviation of age was 67±14 years. The median of times for door-to-CT-scan and onset to treatment were 15 minutes (interquartile range=15) and 2.7 hours (interquartile range=0.6), respectively. The mean and standard deviation for door-to-needle time was 77±18 minutes. No differences were found for any of the variables in terms of arrival date, day part or hour (p>0.05). The median time for door-to-CT- scan was shorter for patients receiving intravenous tissue plasminogen activator treatment than it was for those not receiving such treatment (12 minutes vs. 20 minutes; p=0.02). CONCLUSION The timeliness of the stroke management interventions did not differ significantly in terms of arrival day, day part, or hour.
