Increased frequency and length of high heat episodes are leading to more cardiovascular issues and asthmatic responses among the population of San Juan, the capital of the island of Puerto Rico, USA. An urban heat island effect, which leads to foci of higher temperatures in some urban areas, can raise heat-related mortality. The objective of this research is to map the risk of high temperature in particular locations by creating heat maps of the city of San Juan. The heat vulnerability index (HVI) maps were developed using images collected by satellite-based remote sensing combined with census data...

Prorocentrum mexicanum and P. rhathymum are toxicologically important dinoflagellates, but their relationship is not well defined. We investigated strains from Puerto Rico and Brazil by light and scanning electron microscopies. We provide molecular data from a strain isolated near the type locality of P. rhathymum, and the first morphological and molecular data from the South Atlantic Ocean. The rRNA gene (rDNA) sequences of the Puerto Rican and Brazilian strains were identical, and their morphologies fit the description of P...

BACKGROUND: Racial-ethnic disparities in acute stroke care can contribute to inequality in stroke outcomes. We examined race-ethnic disparities in acute stroke performance metrics in a voluntary stroke registry among Florida and Puerto Rico Get With the Guidelines-Stroke hospitals. METHODS AND RESULTS: Seventy-five sites in the Florida Puerto Rico Stroke Registry (66 Florida and 9 Puerto Rico) recorded 58 864 ischemic stroke cases (2010-2014). Logistic regression models examined racial-ethnic differences in acute stroke performance measures and defect-free care (intravenous tissue plasminogen activator treatment, in-hospital antithrombotic therapy, deep vein thrombosis prophylaxis, discharge antithrombotic therapy, appropriate anticoagulation therapy, statin use, smoking cessation counseling) and temporal trends...

A purified inactivated vaccine (PIV) using the Zika virus (ZIKV) Puerto Rico strain PRVABC59 showed efficacy in monkeys, and is currently in a phase I clinical trial. High-yield manufacture of this PIV is essential for its development and vaccine access. Here we report an infectious cDNA clone-launched platform to maximize its yield. A single NS1 protein substitution (K265E) was identified to increase ZIKV replication on Vero cells (a cell line approved for vaccine production) for both Cambodian FSS13025 and Puerto Rico PRVABC59 strains...

Since the neuraminidase (NA) enzyme of the influenza A virus plays a key role in the process of release of new viral particles from a host cell, it is often a target for new drug design. The emergence of NA mutations, such as H275Y, has led to great resistance against neuraminidase inhibitors, including oseltamivir and zanamivir. Hence, we herein designed a set of derivatives by modifying the amine and/or carboxylic groups of oseltamivir. After being screened for their physicochemical (Lipinski's rule) and toxicological properties, the remaining compounds were submitted to molecular and theoretical studies...

PROBLEM/CONDITION: Since the first U.S. infant conceived with assisted reproductive technology (ART) was born in 1981, both the use of ART and the number of fertility clinics providing ART services have increased steadily in the United States. ART includes fertility treatments in which eggs or embryos are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Women who undergo ART procedures are more likely than women who conceive naturally to deliver multiple-birth infants...

AIMS: Cotton seeds are frequently treated with acid to remove fibers and reduce seed-transmitted diseases. This process also eliminates beneficial bacteria on the seed surface. The goal of this research was to seek and apply beneficial bacteria to acid delinted cotton seeds to evaluate their growth promoting and salt stress alleviating effects in seedlings. METHODS AND RESULTS: Bacteria were isolated from non-cultivated plants in the Malvaceae. Seeds were collected from Portia tree (Thespesia populnea) and wild cotton (Gossypium hirsutum) from coastal and arid areas of Puerto Rico...

BACKGROUND: Prospective cohort studies contribute importantly to understanding the role of lifestyle, genetic, and other factors in chronic disease etiology. METHODS: The American Cancer Society (ACS) recruited a new prospective cohort study, Cancer Prevention Study 3 (CPS-3), between 2006 and 2013 from 35 states and Puerto Rico. Enrollment took place primarily at ACS community events and at community enrollment "drives." At enrollment sites, participants completed a brief survey that included an informed consent, identifying information necessary for follow-up, and key exposure information...

The fall armyworm, Spodoptera frugiperda (J. E. Smith)(Lepidoptera: Noctuidae), is an important agricultural pest of the Western Hemisphere noted for its broad host range, long distance flight capabilities, and a propensity to develop resistance to pesticides that includes a subset of those used in genetically modified corn varieties. These characteristics exacerbate the threat fall armyworm poses to agriculture, with the potential that a resistance trait arising in one geographical location could rapidly disseminate throughout the hemisphere...

BACKGROUND: Injection drug use and its associated blood-borne infections has become a rapidly increasing problem in rural areas of the US recently. Syringe exchange programs have been shown to be effective for reducing transmission of blood borne infections, however access to these prevention efforts may be limited in rural areas. METHODS: This paper utilizes two separate community samples of people who inject drugs (PWID) in Puerto Rico to achieve the following research objectives: (1) compare rural and urban access to syringe exchange programs, free sterile syringes and other HIV/HCV prevention activities, and (2) examine whether utilization of prevention activities is associated with lower injection risk behaviors...

: 130 Background: Oncology Analytics is a cancer care decision support group recently entering the Puerto Rican cancer care marketplace. Bone agents are used in metastatic cancer management to delay the progression of lytic bone metastases. These agents are also used for the treatment of demonstrated osteoporosis with bone densitometry (DEXA scan). Oncology Analytics has found these agents are sometimes used in the absence of lytic metastases or osteoporosis. When this is discussed with treating physicians, practice patterns promptly improve...

: 128 Background: Growth factor use is the largest single category of drug expenditure for US cancer patients. Oncology Analytics is a decision support company that assists physicians in determining the appropriate use of GF based on the NCCN, ASCO, and ASH guidelines and the level one data that underlies these guidelines. We hypothesized that there would be geographic variation among GF preference and in the malleability of those practice patterns after OA entered a market. We determined the proportion of initial pegfilgrastim requests for preauthorization over other types of GF as well as the review outcomes and final drug of choice after OA intervention of inappropriate GF requests across three specific jurisdictions: Florida, Puerto Rico, Georgia and Texas...

Until the past century, mortality trends from coronary heart disease (CHD) and cerebrovascular disease (CVD) were less favorable in Latin than in North America. We calculated age-standardized mortality rates using data from the World Health Organization database over the period 1980 to 2013. To identify significant changes in trends, we performed joinpoint analysis. Since the early 2000's, CHD mortality rates decreased by about 35% in the USA and Canada in both genders; similar decreases were observed in some Latin American countries (i...

Chikungunya virus (CHIKV) causes an acute febrile illness usually accompanied by severe polyarthralgia and polyarthritis. Previous studies have shown that older age, female gender, and some comorbid conditions are associated with chronic CHIKV arthritis. However, the factors associated with acute arthralgia and arthritis are not well known. Thus, we studied the clinical manifestations associated with acute peripheral joint involvement in a group of CHIKV patients from Puerto Rico. Patients with a history of fever for < 7 days evaluated at the emergency department of a university-based hospital were tested for several pathogens including CHIKV...
