Cancer among Hispanic women in South Florida: An 18‐year assessment

Abstract

We experimentally examine a dilute suspension of non‐neutrally buoyant spherical particles migrating in a simple mixing tank at small but finite Reynolds numbers. We observe that the particles spontaneously migrate to repeatable non‐trivial asymptotic locations within toroidal structures, located above and below at‐disk impellers. The asymptotic migration positions include both the exact center of the torus and intermediate higher‐order cluster locations within the flow whose stability is dependent on flow and particle conditions. Furthermore, we note that the particle clusters seem to coincide with the location of unmixed islands within the underlying fluid flow. We also observe a migratory competition when multiple particles are introduced into the flow. © 2006 American Institute of Chemical Engineers AIChE J, 2006

Annual report to the nation on the status of cancer, 1975–2003, featuring cancer among U.S. Hispanic/Latino populations

“…Although incidence rates for Latinos of specific origins could not be calculated, the data on screening and known cancer risk factors among specific Latino groups suggest several general points: first, not all Hispanic populations in the U.S. are alike; 67 second, data reported from various studies on Hispanic populations may not be comparable if the underlying Hispanic populations do not share the same origins, cultural traditions, and immigration status; [68][69][70][71][72] and third, collection of specific Hispanic origin needs to be increased in general population and demographic statistics as well as in the records of persons diagnosed and dying from cancer. 68,73 The cancer incidence data reported here on 90% of U.S. Latinos mirror findings of many other studies on various Latino groups or areas, 45,68,71,[74][75][76][77][78][79][80][81] with a few exceptions. Rate estimates (Trapido et al reported higher rates of cancers of the oral cavity and thyroid in white Latinas 81 and lower rates of stomach cancer in white Latinos, 80 compared with white non-Hispanic women and men, respectively), rank order of top cancer sites (Trapido et al 79 reported for the U.S. that the top 5 cancer sites for Latinos were prostate, lung, colon, stomach, and rectum and for Latinas, cancers of the breast, colon, lung, cervix, and uterine corpus.…”

“…Some differences may be attributed to variation in time periods under study, 68,75,79,81,82 the specific geographies and thus varying origins of the local Hispanic population, 67,72 or limited statistical power to detect differences. 71,83 U.S. Latinos have lower rates of several cancers that are higher in affluent, industrialized countries where tobacco use, obesity, and physical inactivity may be more prevalent. Several cancer sites with higher incidence rates in Latinos have infectious etiologies: human papilloma virus (HPV) in cervical cancer, Helicobacter pylori (H. pylori) in stomach cancer, 84 and Hepatitis B virus (HBV) and Hepatitis C virus (HCV) in liver cancer (and hepatocellular carcinoma).…”

“…Awareness of these issues must stimulate action to eliminate known inequalities before they worsen and are further exacerbated by the aging of the population and inflationary health care costs. 101,103,104,[147][148][149][150] The inequalities in cancer risk, incidence, and prognosis between Latino and non-Latino populations can be reduced by eliminating exposure to infectious agents that cause cancer; with acculturation in the U.S., preventing Latinos from adopting traditionally avoided high risk cancer behaviors; 71,72,74,[151][152][153][154] increasing use of effective clinical prevention services; and assuring that every person diagnosed with cancer has affordable and timely access to state-of-the-art, quality cancer care. [102][103][104]148 We need the continued support and leadership of all the organizations collaborating on this report and the interest of researchers and cancer control specialists throughout the country to focus on continued methodologic and classification improvements in surveillance approaches and to study the issues and determine effective intervention methods for diverse populations.…”

Looking Under the Hispanic Umbrella: Cancer Mortality Among Cubans, Mexicans, Puerto Ricans and Other Hispanics in Florida

“…However, cancer incidence rates from SEER for Hispanic subgroups are generally not available. To date, several studies have explored cancer incidence and mortality differentials between all Hispanics and White non-Hispanics in Florida [2,3,[17][18][19]. By drawing no distinction among the different Hispanic subgroups researchers extrapolate data from one Hispanic subgroup to another where this extrapolation may not always be valid and, in fact, may be misleading [20].…”

Gender- and race-specific comparison of tobacco-associated cancer incidence trends in Florida with SEER regional cancer incidence data

“…Pap screening rates were lowest among black Floridians relative to blacks residing in 29 other states with sufficient data to report race-specific rates [58]. Finally, higher cervical cancer rates in Hispanics [59,60], which comprise 19% of the state population, may also partially account for the higher rates of cervical cancer in white Floridians. Additional research and prevention activities directed at increasing pap screening rates in Florida are needed.…”
