BACKGROUND: Epidemiological studies have shown an association between global warming, air pollution, and allergic diseases. Several air pollutants, including volatile organic compounds, formaldehyde, toluene, nitrogen dioxide (NO2 ), and particulate matter, act as risk factors for the development or aggravation of atopic dermatitis (AD). We evaluated the impact of air pollutants and weather changes on AD patients. MATERIALS AND METHODS: Sixty AD patients ≥5 years of age (mean age: 23.5 ± 12.5 years), living in the Campania Region (Southern Italy), were followed for 18 months. The primary outcome was the effect of atmospheric and climatic factors on signs and symptoms of AD, assessed using the SCORAD (SCORing Atopic Dermatitis) index. We measured mean daily temperature (TOD), outdoor relative humidity (RH), diurnal temperature range (DTR), precipitation, particulate with aerodynamic diameter ≤ 10 µm (PM10 ), NO2 , tropospheric ozone (O3 ), and total pollen count (TPC). A multivariate logistic regression analysis was used to examine the associations of AD signs and symptoms with these factors. An artificial neural network (ANN) analysis investigated the relationships between weather changes, environmental pollutants, and AD severity. RESULTS: The severity of AD symptoms was positively correlated with outdoor temperatures (TOD, DTR), RH, precipitation, PM10 , NO2 , O3 , and TPC. The ANN analysis also showed a good discrimination performance (75.46%) in predicting disease severity based on environmental pollution data, but weather-related factors were less predictive. CONCLUSION: The results of the present study provide evidence that weather changes and air pollutions have a significant impact on skin reactivity and symptoms in AD patients, increasing the severity of the dermatitis. The knowledge of the single variables proportion on AD severity symptoms is important to propose alerts for exacerbations in patients with AD of each age. This finding represents a good starting point for further future research in an area of increasingly growing interest.

BACKGROUND: According to the World Health Organization, air pollution is closely associated with climate change and, in particular, with global warming. In addition to melting of ice and snow, rising sea level, and flooding of coastal areas, global warming is leading to a tropicalization of temperate marine ecosystems. Moreover, the effects of air pollution on airway and lung diseases are well documented as reported by the World Allergy Organization. METHODS: Scientific literature was searched for studies investigating the effect of the interaction between air pollution and climate change on allergic and respiratory diseases. RESULTS: Since 1990s, a multitude of articles and reviews have been published on this topic, with many studies confirming that the warming of our planet is caused by the "greenhouse effect" as a result of increased emission of "greenhouse" gases. Air pollution is also closely linked to global warming: the emission of hydrocarbon combustion products leads to increased concentrations of biological allergens such as pollens, generating a mixture of these particles called particulate matter (PM). The concept is that global warming is linked to the emission of hydrocarbon combustion products, since both carbon dioxide and heat increase pollen emission into the atmosphere, and all these particles make up PM10. However, the understanding of the mechanisms by which PM affects human health is still limited. Therefore, several studies are trying to determine the causes of global warming. There is also evidence that increased concentrations of air pollutants and pollens can activate inflammatory mediators in the airways. Our Task Force has prepared a Decalogue of rules addressing public administrators, which aims to limit the amount of allergenic pollen in the air without sacrificing public green areas. CONCLUSIONS: Several studies underscore the significant risks of global warming on human health due to increasing levels of air pollution. The impact of climate change on respiratory diseases appears well documented. The last decades have seen a rise in the concentrations of pollens and pollutants in the air. This rise parallels the increase in the number of people presenting with allergic symptoms (e.g., allergic rhinitis, conjunctivitis, and asthma), who often require emergency medical care. Our hope is that scientists from different disciplines will work together with institutions, pharmaceutical companies and lay organizations to limit the adverse health effects of air pollution and global warming.
RESUMEN
OBJECTIVE: There are extremely limited data on minority populations, especially Hispanics, describing the clinical epidemiology of acute coronary disease. The aim of this study is to examine the incidence rate of acute myocardial infarction (AMI), in-hospital case-fatality rate (CFR), and management practices among residents of greater San Juan (Puerto Rico) who were hospitalized with an initial AMI. METHODS: Our trained study staff reviewed and independently validated the medical records of patients who had been hospitalized with possible AMI at any of the twelve hospitals located in greater San Juan during calendar year 2007. RESULTS: The incidence rate (# per 100,000 population) of 1,415 patients hospitalized with AMI increased with advancing age and were significantly higher for older patients for men (198) than they were for women (134). The average age of the study population was 64 years, and women comprised 45% of the study sample. Evidence-based cardiac therapies, e.g., aspirin, beta blockers, ACE inhibitors/angiotensin receptor blockers, and statins, were used with 60% of the hospitalized patients, and women were less likely than men to have received these therapies (59% vs. 65%) or to have undergone interventional cardiac procedures (47% vs. 59%) (p<0.05). The in-hospital CFR increased with advancing age and were higher for women (8.6%) than they were for men (6.0%) (p<0.05). CONCLUSION: Efforts are needed to reduce the magnitude of AMI, enhance the use of evidence-based cardiac therapies, reduce possible gender disparities, and improve the short-term prognoses of Puerto Rican patients hospitalized with an initial AMI.

Coronary heart disease (CHD) remains as the main cause of death in most countries of the world including Puerto Rico. Due to the importance of gathering knowledge regarding the harmful effects and risk factors associated with the development of CHD some basic information is reviewed to stimulate the institution of measures for reduction of the prevalence of clinical CHD and its ultimate consequences. Special attention is given in the manuscript of the Puerto Rico Heart Health Program conducted in men aged 45-64 residing in four rural and three urban areas. The Puerto Rico and the Honolulu Study confirmed the initial publication on the epidemiology of coronary heart disease by the Framingham study. The presentation of some data collected among the three studies strengthen the message of avoiding the development of CHD by installing preventive measures for control and reduction of the risk factors. Concurrent data obtained in the three studies is presented. Although the degree of the involvement of the populations is higher in Framingham than in Puerto Rico and Honolulu, the deleterious effects of specific risk factors are harmful in all the three populations. Difference in the prevalence of risk factors among the urban and rural males in Puerto Rico is also illustrated. It is our hope that more intense measures be instituted in Puerto Rico at all levels in order to control risk factors and reduce the incidence of coronary disease in Puerto Rico.

OBJECTIVE: The published literature suggests differences in presenting symptoms for acute myocardial infarction (AMI), management, and outcomes according to gender and age. However, limited information exists on this topic among Hispanics. METHODS: In Puerto Rican patients hospitalized with an initial AMI, we examined differences in presenting symptoms, effective cardiac therapies, and in-hospital mortality as a function of gender and age groups. We reviewed the medical records of patients hospitalized with a validated AMI in 12 greater San Juan, Puerto Rico hospitals during 2007. RESULTS: The average age of 1,415 patients hospitalized with a first AMI was 66 years and 45 % were women. Chest pain (81%) was the most prevalent acute presenting symptom with significant differences in its frequency between women (77%) and men (85%)(p<0.001). Right arm pain, shortness-of-breath/dyspnea, and sweating/ diaphoresis were most prevalent in patients 55-64 years old (45%), compared with patients 75 years and older (29%)(p<0.005). Relative to men and patients < 55 years old, coronary angiography/thrombolytic therapy and percutaneous coronary interventions were used less frequently in women and older patients (>75 years old). During hospitalization for AMI the in-hospital death rate was higher in women (8.6%) than men (6.0%), and increased with advancing age (p<0.05). CONCLUSION: These findings suggest significant gender and age differences in presenting symptoms, management, and early mortality in Puerto Ricans hospitalized with an initial AMI. It remains of considerable importance that health care personnel become aware of these gender and age differences to improve the management and outcomes of these patients.

UNLABELLED: Peripheral artery disease (PAD) of the lower extremities is frequently underdiagnosed and undertreated. The results of screening for PAD in adults attending outpatient clinics at different sites in Puerto Rico from 2007 to 2010 are presented. METHODS: A total of 33 outpatients screening clinics were conducted at different sites throughout the Island. Following the ACC/AHA Guideline recommendations, asymptomatic patients who qualified were screened for PAD using the ankle-brachial index (ABI). An ABI < 0.9 was considered positive for PAD. We estimated the prevalence of PAD in the study population and used logistic regression models to assess factors associated with a positive screening test for PAD. RESULTS: A total of 933 patients were screened for PAD. Out of the 933 patients, the ABI was < 0.9 in 390 (41.8%) of them. Bivariate analysis showed a significant difference in PAD screening results by gender (P = 0.004) and history of arterial hypertension (P = 0.004). Regarding clinical characteristics, leg edema 44.7% (P = 0.001), intermittent claudication 40.3% (P = 0.002), distal extremity coldness 29.0% (P = 0.012), and weak lower extremity pulses 67.5% (P < 0.001) were more prevalent on patients with an ABI < 0.9. In the multivariate analysis, male gender (OR = 1.92, 95% CI: 1.18, 3.11) and arterial hypertension (OR = 2.16, 95% CI: 1.28, 3.65) were significantly associated with PAD after adjusting for specific confounders. CONCLUSIONS: Arterial hypertension, cigarette smoking, diabetes mellitus, and dyslipidemia are known key factors in development of PAD. Practicing physicians must be aware of the importance of an early diagnosis of PAD, particularly in the asymptomatic patient, so as to institute preventive and management measures.

Studies on the association between physical activity and fatal prostate cancer have produced inconclusive results. The Puerto Rico Heart Health Program was a cohort study of a randomly selected sample of 9824 men age 35 to 79 years at baseline who were followed for mortality until 2002. Multiple examinations collected information on lifestyle, diet, body composition, exercise, urban-rural residence, and smoking habits. Physical activity status was measured using the Framingham Physical Activity Index, an assessment of occupational, leisure-time, and other physical activities measured as usual activity over the course of a 24-hour day. Physical activity was stratified into quartiles. Multivariate logistic regression analysis was used to assess the association of physical activity with prostate cancer mortality. Other covariates included age, education, urban-rural residence, smoking, and body mass index. Compared with the lowest level of physical activity (Q1), the risk of prostate cancer mortality was OR = 0.99 (95% CI = 0.64-1.55) for Q2, OR = 1.34 (95% CI = 0.88-2.05) for Q3, and OR = 1.19 (95% CI = 0.75-1.90) for Q4. Further analyses by age group, overweight status, or vigorous physical activity also did not show a significant association between physical activity and prostate cancer mortality. Physical activity did not predict prostate cancer mortality in this group of Puerto Rican men.

Prostate cancer is the number 1 cancer killer among Puerto Rican (PR) men. Plant foods have been inversely associated with prostate cancer. Legumes play a significant role in the PR diet; consumption of legumes in PR (14 lb/capita) was double that of the United States (7 lb/capita). We examined dietary protein consumption (from baseline 24-h dietary recalls) and prostate cancer mortality in the PR Heart Health Program, a cohort study of 9,824 men aged 35-79 years at baseline (1964) with follow-up until 2005. Total protein intake in the cohort was 85 g/day, and sources of protein were 30% vegetable, 30% dairy, 31% animal, and 8% seafood protein. Legume intake was 2.3 servings/day (1/4 cup each). Legume intake was not associated with prostate cancer mortality [comparing highest quartile to lowest quartile-odds ratio (OR) 1.40 [95% confidence interval (CI) 0.91-2.18], P trend 0.17]-nor were total protein, animal, seafood, dairy, or vegetable protein intakes. Consuming 1-2 servings of fruit was inversely associated (OR 0.50, 95% CI 0.32-0.77), whereas consuming more than 2 servings of fruit was not associated with prostate cancer mortality. Thus, we find no association between legumes or protein intake and prostate cancer mortality in this longitudinal cohort study of PR men.

PURPOSE: To examine the association between skin color and all-cause and cardiovascular disease (CVD)-related mortality risk before and after adjusting for selected characteristics and risk factors, we used data on 5,304 men with information on skin color at Exam 3 of the Puerto Rico Heart Health program (PRHHP), a longitudinal study of the incidence of coronary heart disease in Puerto Rican men. METHODS: Mortality was ascertained using hospital and physician records, postmortem records, death certificates, and information from the next of kin. RESULTS: Dark-skinned men exhibited higher age-adjusted mortality rates than light skinned men (10.1 vs. 8.8/10,000 population). There was no association between skin color and all-cause and CVD-related mortality. However, the association between skin color and all-cause mortality varied with area of residence (p for interaction = 0.05). Among men living in urban areas, the risk of all-cause mortality was 28% (95% confidence interval, 1.02-1.61) greater among dark-skinned men than their light-skinned counterparts after adjusting for age, education, BMI, physical activity, and the presence of diabetes. There was no association between skin color and CVD mortality in urban men. Neither all-cause nor CVD mortality was associated with skin color among rural men. CONCLUSION: Our results suggest that skin color may be capturing environmental dynamics that may influence mortality risk among Puerto Rican men.

We report a 22-year-old man who developed shortness of breath after lifting weights and then developed acute heart failure due to rupture of an aneurysm of the right sinus of Valsalva into the right ventricle. The patient developed dyspnea, and clinical findings included tachycardia, wide pulse pressure, bounding carotid and peripheral pulses, pulmonary crackles, and prominent continuous precordial murmur with thrill. Transesophageal echocardiogram with Doppler examination confirmed the diagnosis. The patient underwent surgery with cardioplegia directly infused into the coronary arteries with excision of redundant tissue and closure of the defect with a Dacron patch. He has been asymptomatic since surgery. This condition must to be included in the differential diagnosis for young patients with heart failure.

Eighty percent of coronary deaths occur in people above 65 years of age. Fifty percent of deaths in persons above 85 years of age is due to coronary artery disease. The overall aging of the population and the improvement in survival of patients with coronary artery disease has been creating a growing large population of elderly adults who are elegible for secondary prevention. Multiple clinical trials and research trials have revealed evidence based information confirming the usefulness and effectiveness of secondary prevention of coronary artery disease in the elderly patient. The secondary prevention beneficial results have been obtained by addressing and controlling the predisposing items recognized a coronary risk factors. Secondary preventive measures, including lifestyle modifications and pharmacotherapy, modifying risk factors in elderly patients, have been shown to reduce morbidity and mortality from coronary artery disease. Evidence based data on prevention in elderly patients with coronary artery disease concerning smoking cessation, treatment of hypertension, control of hyperlipidemia, improved dietary patterns, physical activity, moderation in alcohol intake, management of diabetes, weight management, use of antiplatelet agents, beta blockers and renin-angiotensin-andosterone blockers is summarized. Emphasis has been given to AHA/ACC consensus statements on the prevention of coronary artery disease.
