Attitudes,knowledge and wild animals as pets in Costa Rica

Abstract

A nationwide survey in Costa Rica, using Kellert's conceptual framework (Kellert, S. R. 1996. The Value of Life. Washington D.C., Island Press), revealed at least five attitude dimensions toward animals. Overall, Costa Rican adults have a strong sentimental attitude toward animals, an expression of feelings of affection toward animals. In contrast, the materialistic attitude, which regards animals as resources and praises acts of control over them, is weak. This reflects a prevailing opposition to the act of hunting per se, rather than to its potentially detrimental effect on natural populations. There is a strong inquisitive attitude, corresponding to a widespread interest in learning about the biology of animals and their habitats. High scores on the ethical attitude indicate concern for the ethical treatment of animals and nature. The schematic attitude emphasizes the role of aesthetic appearance in the preferences for certain animals and acknowledges feelings of aversion, dislike or fear of some animals. Scores for this attitude were weakly positive. The attitude profile of Costa Ricans is probably incomplete, given the small battery of questions used in this study and differences between this and Kellert's study in the assignment of questions to particular attitudes resulting from the factor analysis. Aesthetic appeal of the animals, compassion, affection and a desire to please and stimulate the children are important motives for the acquisition of wild animals as pets. These positive feelings and a misguided empathy for animals backfire by condemning these pets to an alien environment and inadequate care. The current study also showed that adults who keep wildlife have better biological knowledge than those who never kept wildlife as pets. In addition, Costa Ricans ranked highest in the percentage of correct answers to five questions about animals, in comparison to Kellert's data for US and Japanese citizens (Kellert S.R. 1993. Journal of Social Issues 49: 53–69). Such knowledge of natural history and an animal protection profile, however, do not translate into more animal friendly practices, as seen by the keeping of wildlife as pets under conditions of concern. Rather than changing the attitudes of Costa Ricans toward animals, the challenge is to increase the awareness about the animals' needs and thereby trigger the ethical concern for their well-being.     

Genotype profiles for the Costa Rican population at 7 PCR-based loci

Complete electronic DNA profiles of 2006 randomly selected Costa Ricans, typed for 7 PCR-based loci, are presented. Such data may prove valuable for anthropological and forensic studies of the Costa Rican population.     

Costa Rica's 'White legend': how racial narratives undermine its health care system

A dominant cultural narrative within Costa Rica describes Costa Ricans not only as different from their Central American neighbours, but it also exalts them as better: specifically, as more white, peaceful, egalitarian and democratic. This notion of Costa Rican exceptionalism played a key role in the creation of their health care system, which is based on the four core principles of equity, universality, solidarity and obligation. While the political justification and design of the current health care system does, in part, realize this ideal, we argue that the narrative of Costa Rican exceptionalism prevents the full actualization of these principles by marginalizing and excluding disadvantaged groups, especially indigenous and black citizens and the substantial Nicaraguan minority. We offer three suggestions to mitigate the self-undermining effects of the dominant national narrative: 1) encouragement and development of counternarratives; 2) support of an emerging field of Costa Rican bioethics; and 3) decoupling health and national successes.     

Effect of storage temperatures on growth and survival of Escherichia coli O157: H7 inoculated in foods from a neotropical environment

Escherichia coli O157: H7 has emerged as a new pathogen and is found worldwide. We studied the effect of several storage temperatures on the survival of this bacterium in common foods from a neotropical environment (Costa Rica) because at least seven clinical cases have been reported from the country, and no epidemiological link or probable food association has been described. High (10(6)-10(8) CFU/ml) and low (10(4)-10(6) CFU/ml) populations of E. coli were inoculated (three replications) in ground meat, chopped cabbage, chicken giblets and pasteurized milk and incubated at 0, 6 and 12 degrees C for 24, 48 and 72 h. Vegetables and milk were also stored at 22 degrees C for the same periods. The E. coli O157: H7 enumeration was done according to the methodology described in the Bacteriological Analytical Manual. Populations of E. coli O157: H7 showed either an increasing or decreasing trend, according to temperature, time or food base. Our data indicate that E. coli O157: H7 is capable of surviving and growing in meat, cabbage, milk and chicken giblets; food items commonly consumed by Costa Ricans.     

Impact of Mobility Impairment on Indirect Costs and Health-Related Quality of Life in Multiple Sclerosis

This study was conducted to estimate the indirect costs and health-related quality of life (HRQoL) (utilities) of multiple sclerosis (MS) patients in the United States (US), and to determine the impact of worsening mobility on these parameters. In collaboration with the North American Research Committee on Multiple Sclerosis (NARCOMS) registry we conducted a cross-sectional study of participants who completed the biannual update and supplemental spring 2010 survey. Demographic, employment status, income, mobility impairment, and health utility data were collected from a sample of registry participants who met the study criteria and agreed to participate in the supplemental Mobility Study. Mean annual indirect costs per participant in 2011US$ and mean utilities for the population and for cohorts reporting different levels of mobility impairment were estimated. Analyses included 3,484 to 3,611 participants, based on survey completeness. Thirty-seven percent of registrants were not working or attending school and 46.7% of these reported retiring early. Indirect costs per participant per year, not including informal caregiver cost, were estimated at $30,601±31,184. The largest relative increase in indirect costs occurred at earlier mobility impairment stages, regardless of the measure used. Participants’ mean utility score (0.73±0.18) was lower than that of a similarly aged sample from the general US population (0.87). As with indirect costs, larger decrements in utility were seen at earlier mobility impairment stages. These results suggest that mobility impairment may contribute to increases in indirect costs and declines in HRQoL in MS patients.     

Esophageal cancer incidence rates by histological type and overall: Puerto Rico versus the United States Surveillance,Epidemiology, and End Results population, 1992–2005

Objective: The aim of our study was to compare the age-standardized incidence of esophageal cancer (EC) in Puerto Ricans (PRs) with that for non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic (USH), groups in the United States (US) as reported by the Surveillance, Epidemiology, and End Results program for the 1992–2005 period. Methods: We computed the age-standardized and age-specific incidence (per 100,000 individuals) of EC during 1992–2005 using the World Standard Population as reference. The percent changes for age-standardized rates (ASR), from 1992–1996 to 2001–2005, were calculated. The relative risks (RR) and the standardized rate ratios (SRR) were estimated, along with 95% confidence intervals (CIs). Results: The ASR of adenocarcinomas (AC) showed increases for most racial/ethnic groups from 1992–1996 to 2001–2005. All racial/ethnic groups showed ASR reductions for squamous cell carcinomas (SCC). For both sexes, PRs had lower AC incidences than NHW and USH but higher than NHB. For those younger than 80 years of age, PR men showed higher SCC incidences than NHW but lower than NHB (P < 0.05). The incidence of SCC was about two times higher in PR men than USH men (SRR: 2.16; 95% CI = 1.65–2.88). Among women, the RR for SCC increased with age when comparing PRs to groups in the US. Conclusion: Incidence disparities were observed between PRs and other racial/ethnic groups in the US. These differences and trends may reflect lifestyles of each racial/ethnic group. Further studies are warranted to explain these disparities.     

Área de Conservación Guanacaste,northwestern Costa Rica: Converting a tropical national park to conservation via biodevelopment

The ~30,000 hectare classical Costa Rican Parque Nacional Santa Rosa has used about 35 years and $107 million to be converted to the 169,000 ha government-NGO hybrid Área de Conservación Guanacaste (ACG). This semi-decentralized conservation entity has today a staff of ~150 paraprofessional resident Costa Ricans, biodeveloping at least 650,000 multicellular species (Eucaryotes) into perpetuity for ACG survival through being integrated with its local, regional, national, and international society. ACG began in 1985 as an ongoing exercise of landscape-level ecosystem rescue and restoration of a continuous swath from 6 km out in the Pacific ocean, across dry forested lowlands, up and over the volcanic Cordillera Guanacaste, and down into the rain-forested Caribbean lowlands. It is being impacted by climate change, yet its diverse ecosystems hold hope for major biodiversity survival, albeit in new community assemblages. It quickly became simultaneously a biophysical challenge and an administratively novel challenge in decentralized conservation in a democratic tropical country. ACG specializes at being managed by on-the-job stimulated and trained residents with minimal formal education, searching for ways to involve ACG in its society without damaging its wildness, and pioneering ways to render wild biodiversity to being a welcome member at society's negotiating table. It continues to pay its bills through government subsidy, generous donors, payments for services, project grants, and huge in-kind contributions from mutualisms. ACG hopes that the concept will spread south–south to other tropical countries while they still have some of their wild biodiversity with which to integrate.     

Evolution of the organization for tropical studies

The Organization for Tropical Studies (OTS)/Organización para Estudios Tropicales (OET) has evolved in many ways since its founding in 1963 as a non-profit consortium offering graduate courses and facilitating research in tropical ecology in Costa Rica. By 2002, its international membership included about 65 institutions, including four from Costa Rica. It had developed three Costa Rican field stations (La Selva, Las Cruces, and Palo Verde) with excellent facilities for teaching and research, and it was constructing a new Costa Rican office at the University of Costa Rica. Combinations of internal and external pressures influenced OTS to develop in new directions in the 1980s and 1990s. It became more diversified and more concerned with applied science in its traditional areas of graduate education and research facilitation. The Organization also evolved into new niches: more applied biology, professional education, environmental education and policy, conservation efforts, and an expanded geographic distribution to other Latin American countries. OTS was composed of changing combinations of people (Boards, members, staff) with evolving and competing priorities for limited financial resources. External environmental changes also shaped OTS's evolution. New problems of increased tropical deforestation, the emergence of the biodiversity "crisis" and conservation biology, global climate change, and calls for sustainable development affected OTS constituents and funding priorities of governments and foundations. Both internal and external pressures have in some cases demanded for OTS to improve its relationship with: Costa Rican biologists and their institutions, the Costa Rican government, and Costa Ricans living around the three OTS field stations.     

Significant linkage to airway responsiveness on chromosome 12q24 in families of children with asthma in Costa Rica

Although asthma is a major public health problem in certain Hispanic subgroups in the United States and Latin America, only one genome scan for asthma has included Hispanic individuals. Because of small sample size, that study had limited statistical power to detect linkage to asthma and its intermediate phenotypes in Hispanic participants. To identify genomic regions that contain susceptibility genes for asthma and airway responsiveness in an isolated Hispanic population living in the Central Valley of Costa Rica, we conducted a genome-wide linkage analysis of asthma (n = 638) and airway responsiveness (n = 488) in members of eight large pedigrees of Costa Rican children with asthma. Nonparametric multipoint linkage analysis of asthma was conducted by the NPL-PAIR allele-sharing statistic, and variance component models were used for the multipoint linkage analysis of airway responsiveness as a quantitative phenotype. All linkage analyses were repeated after exclusion of the phenotypic data of former and current smokers. Chromosome 12q showed some evidence of linkage to asthma, particularly in nonsmokers (P < 0.01). Among nonsmokers, there was suggestive evidence of linkage to airway responsiveness on chromosome 12q24.31 (LOD = 2.33 at 146 cM). After genotyping 18 additional short-tandem repeat markers on chromosome 12q, there was significant evidence of linkage to airway responsiveness on chromosome 12q24.31 (LOD = 3.79 at 144 cM), with a relatively narrow 1.5-LOD unit support interval for the observed linkage peak (142–147 cM). Our results suggest that chromosome 12q24.31 contains a locus (or loci) that influence a critical intermediate phenotype of asthma (airway responsiveness) in Costa Ricans. This work was supported by grants HL04370 and HL66289 from the National Institutes of Health.     

Effects of the length of central cancer registry operations on identification of subsequent cancers and on survival estimates

BackgroundPopulation-based cancer survival analyses have traditionally been based on the first primary cancer. Recent studies have brought this practice into question, arguing that varying registry reference dates affect the ability to identify earlier cancers, resulting in selection bias. We used a theoretical approach to evaluate the extent to which the length of registry operations affects the classification of first versus subsequent cancers and consequently survival estimates.MethodsSequence number central was used to classify tumors from the New York State Cancer Registry, diagnosed 2001–2010, as either first primaries (value = 0 or 1) or subsequent primaries (≥2). A set of three sequence numbers, each based on an assumed reference year (1976, 1986 or 1996), was assigned to each tumor. Percent of subsequent cancers was evaluated by reference year, cancer site and age. 5-year relative survival estimates were compared under four different selection scenarios.ResultsThe percent of cancer cases classified as subsequent primaries was 15.3%, 14.3% and 11.2% for reference years 1976, 1986 and 1996, respectively; and varied by cancer site and age. When only the first primary was included, shorter registry operation time was associated with slightly lower 5-year survival estimates. When all primary cancers were included, survival estimates decreased, with the largest decreases seen for the earliest reference year.ConclusionsRegistry operation length affected the identification of subsequent cancers, but the overall effect of this misclassification on survival estimates was small. Survival estimates based on all primary cancers were slightly lower, but might be more comparable across registries.     

Survival from five common cancers in Georgia, 2015–2019 (CONCORD)

BackgroundPopulation-based cancer survival is a key metric of the effectiveness of health systems in managing cancer. Data from population-based cancer registries are essential for producing reliable and robust cancer survival estimates. Georgia established a national population-based cancer registry on 1 January 2015. This is the first analysis of population-based cancer survival from Georgia.MethodsData were available from the national cancer registry for 16,359 adults who were diagnosed with a cancer of the stomach, colon, rectum, breast (women) or cervix during 2015–2019. We estimated age-specific and age-standardised net survival at one, two and three years after diagnosis for each cancer, by sex.ResultsThe data were of extremely high quality, with less than 2% of data excluded from each dataset. For the patients included in analyses, at least 80% of the tumours were microscopically verified.Age-standardised three-year survival from stomach cancer was 30.6%, similar in men and women. For colon cancer, three-year survival was 60.1%, with survival 4% higher for men than for women. Three-year survival from rectal cancer was similar for men and women, at 54.7%. For women diagnosed with breast cancer, three-year survival was 84.4%, but three-year survival from cervical cancer was only 67.2%.ConclusionEstablishment of a national cancer registry with obligatory cancer registration has enabled the first examination of population-based cancer survival in Georgia. Maintenance of the registry will facilitate continued surveillance of both cancer incidence and survival in the country.     

Poverty,insurance, and well-baby care among mainland Puerto Rican children

Using data from the Puerto Rican Maternal and Infant Health Study, we investigate the implications of family income and insurance status for well-baby care among mainland Puerto Ricans. Given the socioeconomic disadvantage of Puerto Ricans, it is critical to understand the extent to which low income and lack of health insurance create barriers to well-baby care and result in low utilization. The analysis shows that the income-to-needs ratio is related to barriers to well-baby care, and a key intervening factor is insurance status. The odds of reporting any barriers to care are lowest among those with both adequate income and private health insurance. Access to insurance is also vital in achieving adequate well-baby care. Uninsured children receive inadequate care more often than children with public or private insurance, especially when their income is also low. Children with public insurance are as likely as children with private insurance to receive an adequate number of well-baby visits, despite the fact that their mothers report more barriers to care.     

From Puerto Rican to pan-ethnic in New York city

Abstract

The increasing diversity of the US population has stimulated interest in racial identification, which is complex for phenotypically heterogeneous groups such as Puerto Ricans. We overcome several limitations of the empirical literature on racial identification among Puerto Ricans with a study that is grounded in the experience of Puerto Rican women in New York City. Our analysis focuses on two questions: How do Puerto Rican women in New York identify themselves racially? What are the sources of racial identification? The results indicate that most Puerto Rican women in New York conflate race and ethnicity by designating their race as either ‘Puerto Rican’ or ‘Hispanic’. Moreover, the decision to ‘become’ pan-ethnic has complex roots. In particular, the effect of skin tone on pan-ethnic identification is conditioned by socioeconomic and neighbourhood characteristics.     

Five-year survival of women with breast cancer in northern Alberta.

Five-year survival rates for all 519 women with breast carcinoma in northern Alberta in 1971 and 1972 were analysed with the use of data from the computerized northern Alberta breast registry and the Alberta cancer registry. The relative 5-year survival was 73%, which is higher than most rates reported from other centres. Lymph node involvement was significant as a prognostic factor, with the relative 5-year survival falling from 92% in the group without lymph node involvement to 58% in the group with three or more involved nodes. The prognosis was also significantly affected by the stage of the disease according to the 1973 TNM classification: the 5-year survival rates ranged from 88% for patients with stage 1 disease to 17% for those with stage IV disease. Women 40 to 59 years of age had a higher survival rate (79%) than those under 40 years (65%) or over 60 years (66%) of age. Analyses by 5-year age groups showed that women 35 to 39 years old had a particularly poor survival rate (59%). Postmenopausal women less than 55 years old had a higher survival rate than did perimenopausal or premenopausal women in the same age group. Further follow-up is indicated to correlate possible high-risk factors with survival.     

Individual and Aggregate Years‐of‐life‐lost Associated With Overweight and Obesity

This study presents nationally representative estimates of individual and aggregate years‐of‐life‐lost (YLLs) associated with overweight and three categories of obesity separately by age, race, smoking status, and gender strata. Using proportional hazards analysis and data from the National Health Interview Survey (NHIS) Linked Mortality Files, we estimated life expectancies for each BMI strata and quantified YLLs by comparing differences between each strata and the normal BMI reference group. Our results provide further evidence that overweight and mild obesity are not associated with a reduction in life expectancy. However, higher BMI categories are associated with lower expected survival. In aggregate, excess BMI is responsible for ～95 million YLLs. White females account for more than two‐thirds of the aggregate YLLs. Unless something is done to reduce the rising prevalence of those with BMIs >35, or to mitigate the impact of obesity or its correlates on YLLs, expected life expectancy for US adults may decrease in the future.     

Socio-economic inequalities in testicular cancer survival within two clinical studies

Background: Testicular cancer is the most common cancer in men under 35 years of age, and has the highest survival for adult male malignancies. Despite the fact that survival is very high, there is evidence that survival differs between socio-economic groups. Methods: We analysed survival patterns for 1606 testicular cancer patients diagnosed during 1984–2001 and recruited to one of two clinical studies. The first was a surveillance study to determine relapse-free survival after orchidectomy in 865 patients with stage I nonseminomatous germ-cell testicular cancer diagnosed during 1984–1991 (TE04). The second study was a trial in which 1174 men with stage I seminomatous germ-cell tumours were randomised to receive radiotherapy or one injection of carboplatin between 1996 and 2001 (TE19). The number of men available for analysis from these two studies was 578 and 1028, respectively. We followed these patients up for their vital status, and assigned them an ecological measure of deprivation. Crude and relative survival were estimated at 5 and 10 years by socio-economic deprivation. Results: No significant socio-economic gradient was seen: 1.3% (95% CI ?0.3% to 3.1%) at 5 years and 2.1% (95% CI ?0.5% to 4.7%) at 10 years. Conclusion: We conclude that, given equal treatment at a given stage of disease, survival from testicular cancer does not depend on socio-economic status. This suggests that the socio-economic gradient in testicular cancer survival in the general population is more likely to be attributable to health care system factors than to personal or socio-economic factors in the men themselves.     

Riding the perennial gale: working-class Puerto Ricans and the involution of colonial capitalism

Hurricane María devastated Puerto Rico in September 2017, deepening an already dire economic situation and amplifying an ongoing wave of out-migration. In the age of permanent man-made climate change, hurricanes, like extended economic crises, are “big events” produced by the capitalist despoiling of nature and labor, further exposing the dispossessed and displaced to structural violence. A colony of the USA since 1898, perhaps Puerto Rico has now once again “changed forever,” as the popular belief goes in the wake of María. If so, these changes will continually be experienced and enacted differently by subjects unevenly positioned in terms of unequal relationships of power and privilege. I propose an empirically informed research orientation that examines the situation of contemporary working-class Puerto Ricans in terms of their strategic responses to the involution of colonial capitalism. As a dimension of social life, working-classness is not contracting but expanding, in the context of an ongoing “debt crisis” better understood in terms of the self-consumption, or involution, of the modality of colonial capitalism established in Puerto Rico in the 1940s. In this light, strategic actions of working-class Puerto Ricans such as migration, informal labor, and subsistence/domestic production are not evidence of alternate modes of being, but part of the very conditions of working-classness today. I conclude by briefly identifying three areas for future research to flesh out the proposed orientation, focusing in the immediate term on responses to María by working-class communities in the island and the diaspora, in interaction with local and US elites.     

Marital status and colon cancer outcomes in US Surveillance, Epidemiology and End Results registries: does marriage affect cancer survival by gender and stage?

Background: Marital status has been associated with outcomes in several cancer sites including breast cancer in the literature, but little is known about colon cancer, the fourth most common cancer in the US. Methods: A total of 127,753 patients with colon cancer were identified who were diagnosed between 1992 and 2006 in the US Surveillance, Epidemiology and End Results (SEER) Program. Marital status consisted of married, single, separated/divorced and widowed. Chi-square tests were used to examine the association between marital status and other variables. The Kaplan–Meier method was used to estimate survival curves. Cox proportional hazards models were fit to estimate the effect of marital status on survival. Results: Married patients were more likely to be diagnosed at an earlier stage (and for men also at an older age) compared with single and separated/divorced patients, and more likely to receive surgical treatment than all other marital groups (all p < 0.0001). The five-year survival rate for the single was six percentage points lower than the married for both men and women. After controlling for age, race, cancer stage and surgery receipt, married patients had a significantly lower risk of death from cancer (for men, HR: 0.86, CI: 0.82–0.90; for women, HR: 0.87, CI: 0.83–0.91) compared with the single. Within the same cancer stage, the survival differences between the single and the married were strongest for localized and regional stages, which had overall middle-range survival rates compared to in situ or distant stage so that support from marriage could make a big difference. Conclusions: Marriage was associated with better outcomes of colon cancer for both men and women, and being single was associated with lower survival rate from colon cancer.     

Elevated asthma morbidity in Puerto Rican children: a review of possible risk and prognostic factors

Latino children represent a significant proportion of all US children, and asthma is the most common chronic illness affecting them. Previous research has revealed surprising differences in health among Latino children with asthma of varying countries of family origin. For instance, Puerto Rican children have a higher prevalence of asthma than Mexican American or Cuban American children. In addition, there are important differences in family structure and socioeconomic status among these Latino populations: Cuban Americans have higher levels of education and family income than Mexican-Americans and Puerto Ricans; mainland Puerto Rican children have the highest proportion of households led by a single mother. Our review of past research documents differences in asthma outcomes among Latino children and identifies the possible genetic, environmental, and health care factors associated with these differences. Based on this review, we propose research studies designed to differentiate between mutable and immutable risk and prognostic factors. We also propose that the sociocultural milieus of Latino subgroups of different ethnic and geographic origin are associated with varying patterns of risk factors that in turn lead to different morbidity patterns. Our analysis provides a blue-print for future research, policy development, and the evaluation of multifactorial interventions involving the collaboration of multiple social sectors, such as health care, public health, education, and public and private agencies.     

Improving but Inferior Survival in Patients with Chronic Lymphocytic Leukemia in Taiwan: A Population-Based Study, 1990–2004

Background

Chronic lymphocytic leukemia (CLL) is much less prevalent in Asian countries. Whether there are differences in survival outcomes between the East and West, however, remain unclear.

Methods

The survival data for CLL patients identified in the Taiwan Cancer Registry database between 1990 and 2004, together with corresponding data in the US Surveillance, Epidemiology, and End Results database, were retrieved. The relative survivals (RS, adjusted for the expected survival in the general population) were estimated in patients diagnosed in three 5-year periods of time.

Results

CLL drastically shortened patients’ life expectancy; more importantly, this negative impact in Taiwan was much larger than that in the US: the 5-year RS in Taiwan and US were 59% and 76%, and the 10-year RS, 45% and 56%, respectively. Nevertheless, survival in Taiwan was better in the periods after 1995 (5-year RS, from 53.0% to 60.6%), a time period corresponding to the introduction of the Taiwan National Health Insurance scheme. Such improvement was largely due to decreased mortality in patients younger than 65 (5-year RS, from 53.5% to 69.1%). Despite the improvement, patients’ RS in Taiwan in recent periods remain steadily 15∼20% inferior to that in the US in both younger and older patient groups.

Conclusions

The improved RS in Taiwan implies that therapeutic advances are changing the prognosis of CLL. The stable RS gap between Taiwanese and the US patients suggests the existence of an ethnic difference in CLL patients’ outcomes.
