Exploring the knowledge and attitudes of college-educated Hispanics toward the transgender community in Puerto Rico.

OBJECTIVE: This study aimed to assess the knowledge and attitudes of a sample of Hispanics in Puerto Rico (PR) toward the transgender community. METHODS: A cross-sectional study addressing Hispanics, aged 21 years or older who lived in PR, was performed from March to September 2021. Participants were invited through online advertisement shared on social media pages. Data were collected via SurveyMonkey and analyzed with Stata 17. Descriptive statistics were employed to summarize findings. RESULTS: A total of 404 participants were sampled. Most were female, 278 (68.8%), had completed at least a bachelor's degree, 292 (72.2%), and referred exposure to trans-related topics during education, 237 (58.7%). Most correctly defined the terms sex, 257 (63.6%), sexual orientation, 334 (82.7%) and transgenderism, 297 (73.5%). The majority also agreed that transgender individuals should be able to change their name, 353 (93.6%) and undergo gender-affirming procedures, 335 (88.9%). Most also believed trans individuals were a valuable part of society, 339 (89.9%) and should be allowed free gender expression, 358 (95.0%). CONCLUSIONS: PR is characterized by a patriarchal, religious, and conservative culture which could promote a negative attitude toward transgender people. Our findings challenged such assumption. The level of knowledge and positive attitude toward trans individuals identified in this study could counteract the existing violence and stigma affecting this community in PR.

Prevalence and co-prevalence of comorbidities among patients with type 2 diabetes mellitus living in Puerto Rico.

This is a descriptive study using healthcare claims data from patients with T2DM from public and private healthcare insurance companies providing services in Puerto Rico in 2013, aimed to estimate the prevalence of comorbidities in this population. Descriptive analyses were performed by sociodemographic, and type of service variables using frequency and percent for categorical data or means (+/-SD) or median (IQR) for continuous variables. Chi-square, Fisher exact or two-sample t-tests were used for comparisons. A total of 3,100,636 claims were identified from 485,866 adult patients with T2DM. Patients older than 65 years represented 48% of the study population. Most patients were women (57%) and had private health insurance (77%). The regions of Metro Area (17%) and Caguas (16%) had the higher number of persons living with T2DM. The overall estimated prevalence of T2DM was 17.4%. The number of claims per patient ranged from 1 to 339. A mean of 6.3 claims (SD±9.99) and a median of 3 claims (Q1 1- Q3 8) per subject were identified. Of the 3,100,636 claims most (74%) were related to the diagnosis of diabetes (59%) and associated to outpatient services (88%). The most prevalent comorbidities were hypertension (48%), hyperlipidemia (41%), neuropathy (21%); renal disease (15%), and retinopathy (13%). A high prevalence and co-prevalence of comorbidities and use of healthcare services were identified in patients with T2DM, especially in older adults. Since most comorbidities were due to diabetes-related conditions, this analysis highlights the importance of early diagnosis and adequate management of T2DM patients to avoid preventable burden to the patient and to the healthcare system.

Telehealth as a potential tool for outreach among women in Puerto Rico.

BACKGROUND: Access to the full spectrum of healthcare should be available to all individuals. After the revocation of the constitutional right to abortion, women have fewer alternatives to unplanned pregnancy. Telehealth provides an additional option for such pregnancies through its remote provision of services. This could benefit women of all social strata. However, data regarding telehealth among underserved populations are limited. OBJECTIVE: This study aimed to evaluate the use of contraception, awareness of abortion services, and receptiveness to telehealth among women in Puerto Rico, a Spanish-speaking minority population. STUDY DESIGN: This was a cross-sectional study of women living in Puerto Rico aged between 21 and 65 years. Data were collected with a self-administered survey via SurveyMonkey from March to December of 2021. Recruitment was done through social media and at the gynecology clinics of the University of Puerto Rico, Medical Sciences Campus and San Juan City Hospital. Analysis was done with Stata, version 14.2. Chi-square and Cochran-Armitage tests were used to evaluate the unadjusted relationship between variables. A P value ≤.05 was considered statistically significant. RESULTS: A total of 286 women were recruited. Of these, 73.3% (189/258) were sexually active, 89.1% (229/257) were heterosexual, and 62.7% (163/260) were not using contraception. In addition, 63.3% (157/248) knew about emergency contraception, yet 42.4% (103/243) were unaware of any sources of access to it; 76.6% (197/257) were unaware of nearby abortion services. A higher education level was associated with knowing about emergency contraception (P<.05) and awareness of sources of access to it (P<.05). However, no significant association was found between a higher education level and awareness of nearby abortion services (P=.799). Regarding telehealth, 65.2% (176/270) were willing to use the service for future gynecologic visits, yet only 18.9% (51/269) were offered telehealth services. No association was found between previous telehealth experiences and willingness to use telehealth for future gynecologic visits (P=.325). CONCLUSION: The lack of contraceptive use and unawareness of nearby abortion services place women at increased risk of unplanned pregnancy and unsafe practices. The gap between knowledge about and access to emergency contraception also calls for action. Telehealth may be of benefit given that most women showed interest in using it, and could be used for educating and providing women in Puerto Rico with contraception and medical abortions, further increasing their access to reproductive healthcare. Clarifying misconceptions and instructing women about safe practices is essential to our role as physicians. Ensuring women's access to adequate services is also vital for upholding their rights to healthcare.

Knowledge and Attitudes about Transgender Healthcare: Exploring the Perspectives of Hispanic Medical Students.

OBJECTIVE: The aim of this study was to explore the knowledge and attitudes about transgender care in Hispanic medical students at the University of Puerto Rico School of Medicine (UPR SOM). METHODS: Medical students at the UPR SOM were invited to participate in a questionnaire to assess their attitudes and knowledge about the healthcare of transgender patients. The data were analyzed as percentages and averages using Stata version 14. RESULTS: A total of 141 medical students completed the survey. The majority of the students (52.5%) reported that they needed to learn more about transgender health issues. Most of the students (60.3%) were not familiar with the hormonal regimens used for gender reassignment and transition and were not knowledgeable about the requirements an individual must fulfil prior to undergoing gender-reassignment surgery. The Likert scale scores for how comfortable students felt about working with transgender patients and becoming known among peers as a doctor that cares for transgender patients were 4.0 (95% CI: 4.0-4.2) and 4.7 (95% CI: 4.6-4.8), respectively. Almost all the medical students (97.9%) thought that transgender patients deserved the same quality of care from medical institutions as heterosexual patients receive. Most of the medical students (87.3%) believed physicians are responsible for the treatment of transgender patients. CONCLUSION: Our study revealed that even though UPR SOM medical students tend to be willing to treat transgender patients, there are limitations to their knowledge and training regarding this specific healthcare topic. Strategies to improve medical student knowledge about and training on these topics must be considered.

Immune Response Persistence and Safety of a Booster Dose of the Tetravalent Dengue Vaccine in Adolescents and Adults Who Previously Completed the 3-dose Schedule 4-5 Years Earlier in Latin America: A Randomized Placebo-controlled Trial.

BACKGROUND: We previously described an increased immune response 28 days after a booster dose of the live, attenuated, tetravalent dengue vaccine (CYD-TDV) in healthy adolescents and adults in Latin America (CYD64, NCT02623725). This follow-up study evaluated immune response persistence and safety of a CYD-TDV booster dose up to Month (M) 24 post-booster. METHODS: This study included 250 participants who previously received 3 primary doses of CYD-TDV in the CYD13 (NCT00993447) and CYD30 (NCT01187433) studies, and who were randomized 4-5 years later to receive a CYD-TDV booster or placebo (3:1). Dengue neutralizing antibodies against the parental dengue virus strains were assessed using the plaque reduction neutralization test (PRNT50) at M6, M12, and M24 post-booster. Post-booster memory B-cell responses were assessed in a subset of participants using the FluoroSpot assay up to M12 post-booster. RESULTS: In the CYD-TDV group (n = 187), dengue neutralizing antibody geometric mean titers (GMTs) declined from the peak at day 28 through to M24 for all serotypes. GMTs at M24 were similar to those at pre-booster among baseline dengue seropositives. A similar trend was observed for baseline dengue seronegatives, albeit at a lower magnitude. Previous vaccination-induced detectable B-cell memory responses in seropositives and seronegatives that decreased to pre-booster levels at M12 post-booster. The CYD-TDV booster dose was well-tolerated. CONCLUSIONS: In baseline dengue seropositives, following a CYD-TDV booster dose administered 4-5 years after primary immunization, dengue neutralizing antibody GMTs and B-cell memory responses peaked in the short-term before gradually decreasing over time. A CYD-TDV booster dose could improve protection against dengue during outbreak periods.

Public Health Academic Alliance for COVID-19 Response: The Role of a National Medical Task Force in Puerto Rico.

Alliances between the government and academic communities can be a key component of the public health response to an emergency such as the coronavirus disease 2019 (COVID-19) pandemic. The Governor of Puerto Rico designated the Puerto Rico Medical Task Force (MTF) COVID-19 to provide direct guidance and evaluation of the government response to the epidemic in Puerto Rico. Several work groups were formed within the MTF to create protocols and provide evidence-based recommendations on different public health aspects. The collaboration between the academia and the government enhanced the Puerto Rican public health response and contributed to the reduction seen in the contagion curve. Healthcare services and hospitals have not reached their maximum patient care capacity and the death toll has been controlled. Incorporating a national MTF with members of the academia into the government structure was beneficial during the COVID-19 response in Puerto Rico. A similar strategy could serve as a model for other states or territories and countries in similar scenarios.

Disparities and Temporal Trends in the Use of Anticoagulation in Patients With Ischemic Stroke and Atrial Fibrillation.

Background and Purpose- Ischemic stroke (IS) secondary to atrial fibrillation (AF) is largely preventable with the use of anticoagulation. We sought to identify race-ethnicity and sex disparities with the use of direct oral anticoagulants (DOACs), aspirin, and warfarin in IS patients with AF and to identify temporal trends in the utilization of these medications. Methods- The FLiPER-AF Stroke Study (Florida Puerto Rico Atrial Fibrillation) included 24 040 IS cases enrolled in the Florida-Puerto Rico Collaboration to Reduce Stroke Registry from 2010 to 2016. Multivariable logistic regression models were performed to evaluate the effect of race-ethnicity and sex on utilization of DOACs, aspirin, and warfarin for stroke prevention in AF after adjustment for sociodemographic, hospital, and clinical factors. Results- Among 24 040 IS cases, 54% were women and 10% black, 12% FL-Hispanics, 4% PR-Hispanic, and 74% whites. From 2010 to 2016, DOAC use increased from 0% to 36%, warfarin use decreased from 51% to 17%, and aspirin use remained relatively stable (42%-40%). After adjustment, blacks had higher odds of warfarin (odds ratio, 1.22; 95% CI, 1.07-1.40) prescription at discharge compared with whites. Men had higher rates of aspirin (42.1% versus 38.8%), warfarin (33.6% versus 28.9%), and DOAC (21.3% versus 19.3%) use compared with women. After adjustment, women had lower odds of being discharged on aspirin (odds ratio, 0.92; 95% CI, 0.86-0.98) or warfarin (odds ratio, 0.91; 95% CI, 0.84-0.99). There was no sex difference in use of DOACs. Conclusions- Our study confirmed the increasing use of DOACs, downtrending use of warfarin, whereas aspirin use remained similar over the years. There are sex and race-ethnicity disparities in anticoagulation use in IS patients with AF. It is critical to understand underlying drivers of these disparities to develop better practice strategies for stroke prevention in patients with AF.

Dengue Vaccine Booster in Healthy Adolescents and Adults in Latin America: Evaluation 4-5 Years After a Primary 3-Dose Schedule.

BACKGROUND: The tetravalent dengue vaccine (CYD-TDV, Dengvaxia, Sanofi Pasteur) demonstrated efficacy in 2 previous phase III trials conducted in endemic countries. Neutralizing antibodies (NAbs) elicited by 3 doses of this vaccine have been associated with efficacy. Long-term follow-up data has shown that NAb immune responses tend to wane over time, after the third dose. This study compared the immune response elicited by a booster (4th) dose of CYD-TDV with the immune responses from the same participants obtained post-dose 3 of the primary series administered 4-5 years earlier. METHODS: This multicenter, observer-blind, randomized, placebo-controlled, phase II noninferiority trial was conducted in healthy adolescents and adults in dengue endemic countries of Latin America (Colombia, Honduras, Brazil, Mexico and Puerto Rico). All participants had been immunized with 3 doses of CYD-TDV in phase II studies conducted 4-5 years earlier. NAb levels against each dengue virus serotype 28 days postbooster or placebo injection were reported. RESULTS: A total of 187 participants received CYD-TDV and 64 received placebo. Prospectively defined noninferiority criteria for dengue NAbs after the booster dose compared with postdose 3 were met for all 4 serotypes. Prospectively defined superiority criteria were met for 3 of the 4 serotypes. CONCLUSIONS: Antidengue NAb levels can be boosted to levels at least as high as, or higher than those observed after completion of the primary 3-dose series, with an additional dose of CYD-TDV 4-5 years after the standard 3-dose vaccination schedule.

Leptospirosis Cases Infected with Uncommon Serogroups, Puerto Rico, 2013-2015.

Leptospirosis is an emerging bacterial zoonosis that is endemic but underrecognized throughout the tropics. Through prospective surveillance for acute febrile illness (AFI) among patients who presented to the emergency department of a hospital located in an urban region of Puerto Rico, four patients with laboratory-confirmed leptospirosis were identified. All patients had signs and symptoms of AFI, including fever, headache, and dehydration. Three patients had leukocytosis with thrombocytopenia and were admitted to the hospital. One hospitalized patient presented with jaundice, icteric sclera, and hematuria and developed rhabdomyolysis, whereas another patient with pulmonary edema was admitted to the intensive care unit. Microscopic agglutination titers among the four patients were highest against serogroups Icterohaemorrhagiae (serovar Mankarso), Australis (serovar Bratislava), Bataviae (serovar Bataviae), and Canicola (serovar Canicola). These case reports demonstrate that infection with these apparently uncommon serogroups can result in illness ranging from mild to life-threatening.

Epidemiology of bronchiolitis: a description of emergency department visits and hospitalizations in Puerto Rico, 2010-2014.

BACKGROUND: Little is known about the epidemiology of bronchiolitis as a clinical diagnosis and its impact on emergency department visits and hospitalizations in tropical and semitropical regions. We described the epidemiology of bronchiolitis emergency visits and hospitalizations, its temporal trend and geographic distribution in Puerto Rico between 2010 and 2014. METHODS: We performed a retrospective descriptive analysis of a representative sample of privately insured children with bronchiolitis from January 2010 to December 2014. Data was provided by the largest private health insurer in Puerto Rico and identified children < 24 months of age with bronchiolitis by International Classification of Diseases, Ninth Revision code 466, 466.11, and 466.19. Chi-square and one-way ANOVA compared sex, age, diagnosis, and severity across the years. Joinpoint Poisson regression analysis evaluated the temporal trend distribution of bronchiolitis hospitalizations per calendar year. A P value less than 0.05 was statistically significant. RESULTS: During the study period, the annual proportion of emergency department visits and hospitalizations due to bronchiolitis increased from 3 to 5%, and 26 to 38%, respectively. The annual incidence rate of hospitalizations was 3.2 per 1000 privately insured children < 24 months. Non-RSV bronchiolitis was the most frequent diagnosis (51%). Hospitalizations occurred year-round, but increased significantly from August through December. Most children hospitalized resided in the metropolitan San Juan (35%) and surrounding urban areas. Total hospital charges decreased from $3.78 to $3.74 million, with an average cost per hospitalization of $4320.12 (11.3% increase; P = 0.0015). CONCLUSIONS: This is the first study that evaluates the epidemiological characteristics of bronchiolitis in a primarily Hispanic population, living in a tropical country, and using data from a privately insured population. We found a small but significant increase in proportion of emergency visits and hospitalizations. Temporal trend shows year-round hospitalizations with an earlier seasonal peak and longer duration, consistent with Puerto Rico's seasonal rainfall throughout the study period. Further studies are needed to elucidate whether this epidemiologic pattern can also be seen in publicly insured children and whether Hispanic ethnicity is a risk factor for increased hospitalizations or is related to health disparities in the US healthcare system.

Building Bridges to Address Health Disparities in Puerto Rico: the "Salud para Piñones" Project.

Over the past several decades, Puerto Ricans have faced increased health threats from chronic diseases, particularly diabetes and hypertension. The patient-provider relationship is the main platform for individual disease management, whereas the community, as an agent of change for the community's health status, has been limited in its support of individual health. Likewise, traditional research approaches within communities have placed academic researchers at the center of the process, considering their knowledge was of greater value than that of the community. In this paradigm, the academic researcher frequently owns and controls the research process. The primary aim is contributing to the scientific knowledge, but not necessarily to improve the community's health status or empower communities for social change. In contrast, the community-based participatory research (CBPR) model brings community members and leaders together with researchers in a process that supports mutual learning and empowers the community to take a leadership role in its own health and well-being. This article describes the development of the community-campus partnership between the University of Puerto Rico School of Medicine and Piñones, a semi-rural community, and the resulting CBPR project: "Salud para Piñones". This project represents a collaborative effort to understand and address the community's health needs and health disparities based on the community's participation as keystone of the process. This participatory approach represents a valuable ally in the development of long-term community-academy partnerships, thus providing opportunities to establish relevant and effective ways to translate evidence-based interventions into concrete actions that impact the individual and community's wellbeing.

Epidemiological Profile of Hispanics Admitted With Acute Myocardial Infarction in Puerto Rico: The Experience of 2007, 2009 and 2011.

BACKGROUND: A limited number of studies have been published about coronary artery disease in Hispanics, particularly among the Puerto Rican population. The aim of this study was to present a clinical epidemiological profile and management practices in patients hospitalized in Puerto Rico with acute myocardial infarction (AMI). METHODS: This secondary data analysis from the Puerto Rico Cardiovascular Surveillance Study included 6,162 patients at 19 hospitals in Puerto Rico, during years 2007, 2009 and 2011. RESULTS: The mean age of the patients diagnosed with AMI was 67 ± 13.6 years old, with women being older than men (P < 0.001). Women had a different risk factor burden when compared to men. Car/walked in was the principal mode of hospital transportation (65.9%). Women received less medications and cardiac procedures when compared to men. While no significant differences in length of hospital stay (LOS) were observed between genders, in-hospital mortality rate was higher in females when compared with males (6.5% vs. 4.5%; P < 0.001). CONCLUSION: Prompt initiatives should be implemented to raise awareness, reduce gender disparities and improve outcomes in patients hospitalized with an AMI in Puerto Rico.

Racial-Ethnic Disparities in Acute Stroke Care in the Florida-Puerto Rico Collaboration to Reduce Stroke Disparities Study.

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. Among ischemic stroke cases, 63% were non-Hispanic white (NHW), 18% were non-Hispanic black (NHB), 14% were Hispanic living in Florida, and 6% were Hispanic living in Puerto Rico. NHW patients were the oldest, followed by Hispanics, and NHBs. Defect-free care was greatest among NHBs (81%), followed by NHWs (79%) and Florida Hispanics (79%), then Puerto Rico Hispanics (57%) (P<0.0001). Puerto Rico Hispanics were less likely than Florida whites to meet any stroke care performance metric other than anticoagulation. Defect-free care improved for all groups during 2010-2014, but the disparity in Puerto Rico persisted (2010: NHWs=63%, NHBs=65%, Florida Hispanics=59%, Puerto Rico Hispanics=31%; 2014: NHWs=93%, NHBs=94%, Florida Hispanics=94%, Puerto Rico Hispanics=63%). CONCLUSIONS: Racial-ethnic/geographic disparities were observed for acute stroke care performance metrics. Adoption of a quality improvement program improved stroke care from 2010 to 2014 in Puerto Rico and all Florida racial-ethnic groups. However, stroke care quality delivered in Puerto Rico is lower than in Florida. Sustained support of evidence-based acute stroke quality improvement programs is required to improve stroke care and minimize racial-ethnic disparities, particularly in resource-strained Puerto Rico.

Clinical Manifestations Associated with Peripheral Joint Involvement in Patients with Acute Chikungunya Virus Infection.

AbstractChikungunya 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. All patients with laboratory-positive CHIKV infection were studied. Demographic features, clinical manifestations, and comorbidities were determined. Patients with and without peripheral joint involvement were compared using bivariable and multivariable analyses. In total, 172 patients with CHIKV fever were evaluated; 52.9% were women. The mean (standard deviation) age was 21.1 years (19.3). Peripheral arthralgia and/or arthritis were seen in 156 (90.7%) patients. In the multivariable analysis adjusted for age and gender, peripheral joint involvement was associated with myalgia (odds ratio [OR] = 4.65, 95% confidence interval [CI] = 1.48-14.72), back pain (OR = 16.77, 95% CI = 3.07-313.82), ocular pain (OR = 8.88, 95% CI = 1.65-165.19), headache (OR = 3.63, 95% CI = 1.06-12.53), anorexia (OR = 5.68, 95% CI = 1.87-18.97), and nausea (OR = 6.88, 95% CI = 2.05-31.49). In conclusion, in this population of patients with acute CHIKV infection, peripheral joint involvement was associated with myalgia and back pain as well as nonmusculoskeletal manifestations such as headache, ocular pain, anorexia, and nausea.

Incidence of dengue virus infection in school-aged children in Puerto Rico: a prospective seroepidemiologic study.

Dengue is a potentially fatal acute febrile illness caused by the mosquito-borne dengue viruses (DENV-1 to -4). To estimate DENV seroincidence in school-aged children, a 1-year prospective cohort study was conducted in Patillas, Puerto Rico; 10- to 18-year-olds (N = 345) were randomly selected from 13 public schools. At enrollment, 49.8% of the entire cohort had DENV immunoglobulin G (IgG) anti-DENV antibodies, and there were individuals with neutralizing antibodies specific to each of the four DENV. The mean age of participants with incident DENV infection was 13.4 years. The 1-year seroincidence rate was 5.6%, and 61.1% of infections were inapparent. Having IgG anti-DENV at enrollment was associated with seroincidence (risk ratio = 6.8). Acute febrile illnesses during the study period were captured by a fever diary and an enhanced and passive surveillance system in the municipios of Patillas and Guayama. In summary, at enrollment, nearly one-half of the participants had a prior DENV infection, with the highest incidence in the 10- to 11-year-olds, of which most were inapparent infections, and symptomatic infections were considered mild.

Physician survey to determine how dengue is diagnosed, treated and reported in puerto rico.

Dengue is a major cause of morbidity in Puerto Rico and is well-known to its physicians. Early case identification and timely initiation of treatment for patients with severe dengue can reduce medical complications and mortality. To determine clinical management and reporting practices, and assess knowledge of dengue and its management, a survey was sent to 2,512 physicians with a medical license in Puerto Rico. Of the 2,313 physicians who received the survey, 817 (35%) completed the questionnaire. Of the respondents, 708 were currently practicing medicine; 138 were board certified (Group 1), 282 were board eligible (Group 2), and 288 had not finished residency (Group 3). Although respondents clinically diagnosed, on average, 12 cases of dengue in the preceding three months, 31% did not report any suspected cases to public health officials while about half (56%) reported all cases. Overall, 29% of respondents correctly identified early signs of shock and 48% identified severe abdominal pain and persistent vomiting as warning signs for severe dengue with the proportion of correct respondents highest in Group 1. Reportedly about sixty percent (57%) appropriately never give corticosteroids or prophylactic platelet transfusions to dengue patients. One third (30%) of respondents correctly identified administration of intravenous colloid solution as the best treatment option for dengue patients with refractory shock and elevated hematocrit after an initial trial of intravenous crystalloids, and nearly one half (46%) correctly identified administration of a blood transfusion as the best option for dengue patients with refractory shock and decreased hematocrit after a trial of intravenous crystalloids. Even though dengue has been endemic in Puerto Rico for nearly 4 decades, knowledge of dengue management is still limited, compliance with WHO treatment guidelines is suboptimal, and underreporting is significant. These findings were used to design a post graduate training course to improve the clinical management of dengue.

Geographic distribution of risk of death due to homicide in Puerto Rico, 2001–2010 / Distribución geográfica del riesgo de muerte por homicidio en Puerto Rico,2001–2010

Objective. To raise awareness of the impact of homicides in Puerto Rico based on the findings of the spatial and temporal distribution of homicides and the use of firearms, by age and gender, using reports of interpersonal violent deaths from the Institute of Forensic Science (IFS) headquartered in San Juan, Puerto Rico. Methods. This was a descriptive study of all homicide incidents in Puerto Rico reported by the IFS for the period 2001–2010. For each of the 8 542 cases, data analyzed included age, sex, municipality of incident, date of death, and mechanism. Crude sex- and age-specific mortality rates for Puerto Rico and for each municipality per year and for the 10-year period were calculated. Cumulative rate and cumulative risks were estimated and defined as lifetime risk. The relative distribution of cumulative rates for each municipality was categorized into quartiles of highest to lowest risk and displayed as a map. Results. The risk of homicide death among males is 13 times greater than among females. The highest rates were observed among males 20–24 years of age (198.4 homicides per 100 000). In any given year, firearms were used in at least 80% of homicides. The average lifetime risk of homicide death for males is 1 in 34. Conclusions. Young adult males with access to firearms are at greatest risk of homicide in Puerto Rico. Also, highly urbanized municipalities are at highest risk; however, certain nonurban municipalities along the coast also have a very high homicide risk. Top priorities should be applying the WHO “ecological model” for violent injury prevention and establishing a surveillance system that will assist in identifying the role that socioeconomics, illegal firearms trade, and drug trafficking are playing.

Objetivo. Concientizar sobre la repercusión de los homicidios en Puerto Rico con base en los resultados de la distribución espacial y temporal de los homicidios y el uso de las armas de fuego, según la edad y el sexo, a partir de los informes del Instituto de Ciencias Forenses (ICF), con sede en San Juan, Puerto Rico, sobre defunciones por violencia interpersonal. Métodos. Estudio descriptivo de todos los incidentes de homicidio ocurridos en Puerto Rico informados por el ICF durante el período del 2001 al 2010. La edad, el sexo, el municipio del incidente, la fecha de muerte y el mecanismo fueron los datos analizados en cada uno de los 8 542 casos. Se calcularon las tasas brutas de mortalidad específicas de cada sexo y edad en Puerto Rico y en cada municipio, por año y durante el período de 10 años. Se calcularon también las tasas y los riesgos acumulados y se definieron como riesgo durante toda la vida. La distribución relativa de las tasas acumuladas para cada municipio se clasificó en cuartiles, del riesgo más alto al más bajo, y se ilustró en un mapa. Resultados. El riesgo de muerte por homicidio en varones es 13 veces mayor que en mujeres. Las tasas más elevadas se observaron en hombres de 20 a 24 años de edad (198,4 homicidios por 100 000). Cualquiera que fuera el año escogido, en al menos 80% de los homicidios se utilizaron armas de fuego. En varones, el riesgo promedio de morir por homicidio durante toda la vida es de 1/34. Conclusiones. Los jóvenes varones adultos con acceso a las armas de fuego están sometidos a un mayor riesgo de homicidio en Puerto Rico. Además, en los municipios muy urbanizados el riesgo es más alto; sin embargo, en ciertos municipios no urbanos de la costa también hay un riesgo de homicidio muy alto. Las máximas prioridades deben ser aplicar el “modelo ecológico” de la OMS para prevenir las lesiones violentas y establecer un sistema de vigilancia que ayude a determinar la función que desempeñan las condiciones socioeconómicas, el comercio ilegal de armas de fuego y el tráfico de drogas.

Dengue deaths in Puerto Rico: lessons learned from the 2007 epidemic.

BACKGROUND: The incidence and severity of dengue in Latin America has increased substantially in recent decades and data from Puerto Rico suggests an increase in severe cases. Successful clinical management of severe dengue requires early recognition and supportive care. METHODS: Fatal cases were identified among suspected dengue cases reported to two disease surveillance systems and from death certificates. To be included, fatal cases had to have specimen submitted for dengue diagnostic testing including nucleic acid amplification for dengue virus (DENV) in serum or tissue, immunohistochemical testing of tissue, and immunoassay detection of anti-DENV IgM from serum. Medical records from laboratory-positive dengue fatal case-patients were reviewed to identify possible determinants for death. RESULTS: Among 10,576 reported dengue cases, 40 suspect fatal cases were identified, of which 11 were laboratory-positive, 14 were laboratory-negative, and 15 laboratory-indeterminate. The median age of laboratory-positive case-patients was 26 years (range 5 months to 78 years), including five children aged < 15 years; 7 sought medical care at least once prior to hospital admission, 9 were admitted to hospital and 2 died upon arrival. The nine hospitalized case-patients stayed a mean of 15 hours (range: 3-48 hours) in the emergency department (ED) before inpatient admission. Five of the nine case-patients received intravenous methylprednisolone and four received non-isotonic saline while in shock. Eight case-patients died in the hospital; five had their terminal event on the inpatient ward and six died during a weekend. Dengue was listed on the death certificate in only 5 instances. CONCLUSIONS: During a dengue epidemic in an endemic area, none of the 11 laboratory-positive case-patients who died were managed according to current WHO Guidelines. Management issues identified in this case-series included failure to recognize warning signs for severe dengue and shock, prolonged ED stays, and infrequent patient monitoring.

Geographic distribution of risk of death due to homicide in Puerto Rico, 2001-2010.

OBJECTIVE: To raise awareness of the impact of homicides in Puerto Rico based on the findings of the spatial and temporal distribution of homicides and the use of firearms, by age and gender, using reports of interpersonal violent deaths from the Institute of Forensic Science (IFS) headquartered in San Juan, Puerto Rico. METHODS: This was a descriptive study of all homicide incidents in Puerto Rico reported by the IFS for the period 2001-2010. For each of the 8 542 cases, data analyzed included age, sex, municipality of incident, date of death, and mechanism. Crude sex- and age-specific mortality rates for Puerto Rico and for each municipality per year and for the 10-year period were calculated. Cumulative rate and cumulative risks were estimated and defined as lifetime risk. The relative distribution of cumulative rates for each municipality was categorized into quartiles of highest to lowest risk and displayed as a map. RESULTS: The risk of homicide death among males is 13 times greater than among females. The highest rates were observed among males 20-24 years of age (198.4 homicides per 100 000). In any given year, firearms were used in at least 80% of homicides. The average lifetime risk of homicide death for males is 1 in 34. CONCLUSIONS: Young adult males with access to firearms are at greatest risk of homicide in Puerto Rico. Also, highly urbanized municipalities are at highest risk; however, certain non-urban municipalities along the coast also have a very high homicide risk. Top priorities should be applying the WHO "ecological model" for violent injury prevention and establishing a surveillance system that will assist in identifying the role that socioeconomics, illegal firearms trade, and drug trafficking are playing.
