    1997-02-07

    The main goal of the Central New Mexico Section this year was to increase attendance at the local meetings. Throughout the course of the year attendance at the meeting more than doubled. This was brought on by several factors: having the meeting spread throughout the section (Albuquerque, Santa Fe, Las Vegas, Socorro, Los Alamos); supplementing the ACS National Tour speakers with interesting local sections speakers; and making full use of the newly formed Public Relations Committee. Activities during 1996 are summarized.

    2012-01-01

    We report the results of a study conducted during 1990–2006 with 89 cases of American visceral leishmaniasis in Chiapas State in southeastern Mexico and a seroprevalence study performed with 726 persons and 224 dogs that lived near cases of American visceral leishmaniasis. Clinical aspects, epidemiologic profiles, and risk factors are described. Most cases were in children ≤ 5 years of age, the prevalence of seropositive persons was 77%. The main risk factors associated with this disease were having 1–3 rooms in a house compared with ≥ 4 rooms, having a roof that was not made of cement, and having domestic animals. In contrast, only 19% of dogs were seropositive, suggesting that this species is not important in the transmission cycle of Leishmania. These data indicate that active transmission is taking place in the central valley of Chiapas State, Mexico, in communities located < 1,000 meters above sea level near the Grijalva River.

    A recent finding of low levels of docosahexaenoic acid (DHA) in the milk of lactating Hispanic and non-Hispanic white women in New Mexico prompted a study of the DHA content of the breast milk and diets of American Indian women in the state. Nineteen urban American Indian women (18 to 40 years) who had been lactating for 1 to 6 months and who were attending clinics at the University of New Mexico Hospital were enrolled in a cross-sectional study that was conducted between June 2005 and February 2009. Descriptive statistics and correlations were performed. The mean fat content of the breast milk was 4.67±1.9 g/dL and the mean DHA proportion of the milk fat was 0.097%±0.035%, which is a low value relative to international norms. The low DHA content of the milk could be accounted for by the women's low dietary intake of DHA (median=30 mg). The DHA percentage in the women's milk fat was positively correlated with dietary intake of DHA (r=0.67; P<0.001). This study shows that the DHA content of the breast milk of urban American Indian women attending clinics at a university hospital in New Mexico is well below levels widely acknowledged as being healthful for infants who rely mainly on breast milk for their supply of DHA.

    We studied 1,179 North American travelers who visited Mexico from 2005 to 2007. Travelers' diarrhea (TD) was reported by 521 (44%) participants. Among subjects with TD, 218 cases were examined for cryptosporidiosis by polymerase chain reaction (PCR) and enzyme-linked immunoassays (ELISA). There were 14 (6%) cases of cryptosporidiosis and 141 cases (64%) of bacterial diarrhea. Compared with bacterial diarrhea, a longer stay in Mexico was a risk factor for cryptosporidiosis. Additionally, Cryptosporidium cases passed greater number of watery stools (P < 0.05), suffered more episodes of diarrhea (P ≤ 0.05), and were more likely to experience tenesmus (P ≤ 0.05) compared with bacterial causes of TD. ELISA detected seven (3%) cases of Cryptosporidium, whereas PCR identified an additional seven cases (6%). Speciation by 18SrRNA sequencing showed that 13 cases were caused by C. parvum and only 1 case was caused by C. hominis. ELISA showed a sensitivity of 50% and specificity of 100% compared with PCR.

  3. Caesarean sections in Mexico: are there too many?

    PubMed

    Gonzalez-Perez, G J; Vega-Lopez, M G; Cabrera-Pivaral, C; Muñoz, A; Valle, A

    2001-03-01

    This paper seeks to quantify the magnitude of caesarean sections in Mexican public health-care institutions in recent years, to characterize the evolution of caesarean section rates (CSR) during the last decade, and to estimate the possible economic cost caused by the excess of caesareans performed in these institutions. The study is based on data obtained from the health sector, both for Mexico in the 5-year period 1993-97 and for the Mexican State of Jalisco between 1983 and 1998. Linear regression analysis was used to evaluate time series, and "excess of caesareans" was considered the number of caesarean deliveries performed above the admissible 15% CSR. The results reflect that on the national level, more than one-quarter of the deliveries handled by public institutions ended in caesarean section for each analyzed year, and if the deliveries performed in private institutions are included, the national rate is around 30%. A marked increase in CSR can be observed in Jalisco between 1983 and 1998 (almost 50%); and the cost for the nation of this CSR excess in financial terms is highly significant: several millions of dollars--obtained from public funds--are spent annually and unnecessarily by health services. The findings suggest that the increase in CSR is a public health problem that has not been satisfactorily faced by the health sector authorities. Many unnecessary caesareans would undoubtedly be avoided if the policies of these public health-care institutions were to consider, as a priority, both the known higher risk implicit in a caesarean for the health of the mother and child, and the economic impact on the country and its health institutions of the excessive number of caesareans performed yearly.

  4. Habitat Suitability Index Models: Gulf of Mexico American Oyster

    The American or eastern oyster (Crassostrea virrinica [Gmelin]), a bivalve in the family Ostreidae, is an important commercia and recreational species along the Atlantic and Gulf of Mexico coasts of North America and other areas (U.S. Pacific coast and Hawaii) where it has been introduced (Galtsoff 1964). It evolved over the last 25 million years (Miocene and Pliocene epochs) from an ancestral, Atlantic-Pacific species that also gave rise to the Central American oyster of the Pacific coast, Crassostrea corteziensis (Hertlein) (Stenzel 1971). It evolved to fill a eurytopic niche in coastal estuaries where it forms massive reefs in nearshore bays, sounds, lagoons, and river mouths. Its existence depends on suitable substratum (cultch and firm bottom sediments) and acceptable sal-inity conditions. The location and distribution of oyster reefs in a salt marsh-estuari ne ecosystem are not acci denta 1; rather, they result from the interacti on of many bi 01 ogi ca 1, chemica1, geo1ogi ca1, and phys i ca 1 processes (Butler 1954a; Marshall 1954; Bahr and Lanier 1981).

    1988-02-01

    Focus in this discussion of Mexico is on the following: geography; the people; history; political conditions; the economy; foreign relations; and relations between the US and Mexico. As of July 1987, the population of Mexico numbered 81.9 million with an estimated annual growth rate of 2.09%. 60% of the population is Indian-Spanish (mestizo), 30% American Indian, 9% white, and 1% other. Mexico is the most populous Spanish-speaking country in the world and the 2nd most populous country in Latin America. Education is decentralized and expanded. Mexico's topography ranges from low desert plains and jungle-like coastal strips to high plateaus and rugged mountains. Hernan Cortes conquered Mexico in 1919-21 and founded a Spanish colony that lasted for almost 300 years. Independence from Spain was proclaimed by Father Miguel Hidalgo on September 16, 1810; the republic was established on December 6, 1822. Mexico's constitution of 1917 provides for a federal republic with a separation of powers into independent executive, legislative, and judicial branches of government. Significant political themes of the administration of President Miguel de la Madrid Hurtado, who began his 6-year term in 1982, have been restructuring the economy, liberalizing trade practices, decentralizing government services, and eliminating corruption among public servants. In 1987, estimates put the real growth of the Mexican economy at 1.5%; the gross domestic product (GDP) had shrunk by 3.5% in 1986. Yet, on the positive side, Mexico's international reserves increased to record levels in 1987 (to about $15 billion), and its current account surplus reached more than $3 billion. Mexico has made considerable progress in moving to restructure its economy. It has substantially reduced impediments to international trade and has moved to reduce the number of parastatal firms. 1987 was the 2nd consecutive year in which Mexico recorded triple-digit inflation; inflation reached 158.8%. Other problems include

    Chagas disease is a parasitic infection caused by the protozoan Trypanosoma cruzi, a flagellated organism that is transmitted mainly to humans through the infected feces of triatomine kissing bugs (vector transmission in endemic areas) or by transfusion of infected blood, donations of infected organ, or transmission from an infected mother to her child at birth. Chagas disease was first described in 1909 by the Brazilian physician Carlos Chagas, and due to the parasite's distribution throughout North, Central and South America, the disease is commonly known as American trypanosomiasis. However, this disease is now present in non-endemic countries such as Canada, the United States of America, and several countries in Europe (principally Spain). Moreover, Chagas disease was recently designated by the World Health Organization as one of the main neglected tropical diseases. The aim of this review is to summarize the research efforts recently described in studies conducted in Mexico on Chagas disease. In this country, there are no existing vector control programs. In addition, there is no consensus on the diagnostic methods for acute and chronic Chagas disease in maternity wards and blood banks, and trypanocidal therapy is not administered to chronic patients. The actual prevalence of the disease is unknown because no official reporting of cases is performed. Therefore, the number of people infected by different routes of transmission (vector, congenital, blood transfusion, organ transplantation, or oral) is unknown. We believe that by promoting education about Chagas disease in schools starting at the basic elementary level and including reinforcement at higher education levels will ensure that the Mexican population would be aware of this health problem and that the control measures adopted will have more acceptance and success. We hope that this review sensitizes the relevant authorities and that the appropriate measures to reduce the risk of infection by T. cruzi

    We set out to describe the pattern of lung function growth in Mexican students from 8-20 years of age, using internationally accepted equipment and methodology, and to compare it to values reported for Mexican-American children. Out of a total of 6,803 students from primary school to high school studied cross-sectionally in the Mexico City metropolitan area, we selected 4,009 asymptomatic, nonobese, nonsmoker subjects to generate spirometric prediction equations. We describe regression equations for the main spirometric variables (log transformed) based on age, height, and weight, and separated for males and females. Spirometric function in the population studied was above that predicted for European (Quanjer et al. [1987] Pediatr Pulmonol 19:135-142) or Mexican-American children, for the same age, height, and gender. On average, forced expiratory volume in 1 sec (FEV(1)) in Mexican children was 9.5% above that of Europeans (Quanjer et al. [1987] Pediatr Pulmonol 19:135-142), 14% and 5% above Hispanics reported by (Coultas et al. [1988] Am Rev Respir Dis 138:1386-1392) and (Hsu et al. [1979] J Pediatr 95:14-23), respectively, and 5% above Mexican-Americans from the third National Health and Nutrition Examination Survey study. Similarly, FVC was 8%, 14%, 8%, and 5.6% above the figures predicted by the same authors. The largest errors of prediction of foreign equations occurred in extremely tall or short subjects, and therefore a single proportional adjustment is unfeasible.

    Mexico harbors great cultural and ethnic diversity, yet fine-scale patterns of human genome-wide variation from this region remain largely uncharacterized. We studied genomic variation within Mexico from over 1000 individuals representing 20 indigenous and 11 mestizo populations. We found striking genetic stratification among indigenous populations within Mexico at varying degrees of geographic isolation. Some groups were as differentiated as Europeans are from East Asians. Pre-Columbian genetic substructure is recapitulated in the indigenous ancestry of admixed mestizo individuals across the country. Furthermore, two independently phenotyped cohorts of Mexicans and Mexican Americans showed a significant association between subcontinental ancestry and lung function. Thus, accounting for fine-scale ancestry patterns is critical for medical and population genetic studies within Mexico, in Mexican-descent populations, and likely in many other populations worldwide.

    Gilliland, F.; Mahler, R.; Davis, S.

    1998-01-01

    OBJECTIVES—To ascertain non-ceremonial tobacco use among rural American Indians in New Mexico (United States).
DESIGN—A geographically targeted telephone survey.
SETTING—Rural New Mexico.
PARTICIPANTS—American Indian residents aged 18 years and older.
MAIN OUTCOME MEASURES—Prevalence of ever-smokers and current smokers of cigarettes and ever-users and current users of smokeless tobacco, number of cigarettes smoked, and prevalence of cigarette smoking quitting behaviour.
RESULTS—Of the 1266 respondents, 38.5% (95% confidence interval (CI) = 34.5% to 42.1%) reported ever smoking, and 16.3% (95% CI = 13.5% to 19.0%) reported being current smokers. Current smokers averaged 7.6 (95% CI = 6.0 to 9.3) cigarettes per day. Current smoking prevalence was highest among men and lowest among college graduates. Prevalence of smokeless tobacco use was 24.1% for ever-use and 7.2% for current use and showed a strong male predominance of use.
CONCLUSIONS—The prevalence of current smokers among rural American Indians in New Mexico was lower than among American Indians of other regions in the United States, all New Mexicans, and the national population as a whole. Although smoking prevalence was lower among American Indians in New Mexico, variation by sex and education followed the same patterns as reported among American Indians of other regions.

The International School of American Archaeology and Ethnology was one of the first attempts by American anthropologists to carry out systematic research in foreign lands. Motivated partly by a wish to strengthen the quality of American anthropology, Franz Boas succeeded in gaining the cooperation of several European and American institutions. The purpose of the school was to conduct rigorous anthropological investigations in Mexico. Obsessed with professionalizing the discipline, Boas failed to take into account the turbulent political climate of Mexico when planning the school. Although it did good work for a number of years (1910-1914), the school was broken up forever in 1914 because of the Mexican revolution. Attempts at resurrection failed for numerous reasons.

    The background notes on Mexico provide text and recent statistical information on the geography, population, government, economy, and foreign relations, specifically the North American Free Trade Agreement with US. The 1992 population is estimated at 89 million of which 60% are mestizo (Indian-Spanish), 30% are American Indian, 9% are Caucasian, and 1% are other. 90% are Roman Catholic. There are 8 years of compulsory education. Infant mortality is 30/1000 live births. Life expectancy for males is 68 years and 76 years for females. The labor force is comprised of 30% in services, 24% in agriculture and fishing, 19% in manufacturing, 13% in commerce, 7% in construction, 4% in transportation and communication, and .4% in mining. There are 31 states and a federal district. Gross domestic product (GDP) per capita was $3200 in 1991. Military expenditures were .5% of GDP in 1991. The average inflation rate is 19%. Mexico City with 20 million is the largest urban center in the world. In recent years, the economy has been restructured with market oriented reforms; the result has been a growth of GDP of 3.6% in 1991 from 2% in 1987. Dependence on oil exports has decreased. There has been privatization and deregulation of state-owned companies. Subsidies to inefficient companies have been stopped. Tariff rates were reduced. The financial debt has been reduced and turned into a surplus of .8% in 1992. Mexico's foreign debt has been reduced from its high in 1987 of $107 billion. Agricultural reforms have been ongoing for 50 years. Land was redistributed, but standards of living and productivity have improved only slightly. Rural land tenure regulations have been changed, and other economic reforms are expected. Mexico engages in ad hoc international groups and is selective about membership in international organizations.

  18. Birthweight distributions in Mexico City and among US Southwest Mexican Americans: the effect of altitude.

    1992-01-01

    In this study birthweight distributions for Mexican Americans and Mexico City were compared. Sharp differences in the two distributions were nearly eliminated by controlling for altitude. The small remaining excess in low birthweight in Mexico City appears to be due to a slight overrepresentation of tertiary hospital deliveries, and possibly to a greater prevalence of pathological conditions. The results are consistent with the favorable low birthweight rate reported for Mexican Americans and illustrate the need to adjust for altitude in studies of low birthweight. PMID:1609901

    Objectives. We investigated whether Mexican immigration to the United States exerts transnational effects on substance use in Mexico and the United States. Methods. We performed a cross-sectional survey of 2336 Mexican Americans and 2460 Mexicans in 3 Texas border metropolitan areas and their sister cities in Mexico (the US–Mexico Study on Alcohol and Related Conditions, 2011–2013). We collected prevalence and risk factors for alcohol and drug use; Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, alcohol-use disorders; and 2 symptoms (hazardous use and quit or control) of drug use disorder across a continuum of migration experiences in the Mexican and Mexican American populations. Results. Compared with Mexicans with no migrant experience, the adjusted odds ratios for this continuum of migration experiences ranged from 1.10 to 8.85 for 12-month drug use, 1.09 to 5.07 for 12-month alcohol use disorder, and 1.13 to 9.95 for 12-month drug-use disorder. Odds ratios increased with longer exposure to US society. These findings are consistent with those of 3 previous studies. Conclusions. People of Mexican origin have increased prevalence of substance use and disorders with cumulative exposure to US society. PMID:26562124

    The Gulf of Mexico is part of the Atlantic Warm Pool, a feature that drives oceanic moisture flux to the surrounding continent. It is connected to the North Atlantic Ocean via the loop current, which transports salt and heat from the Caribbean and Gulf of Mexico poleward via the Gulf Stream. As such, variations in Gulf of Mexico sea surface temperature (SST) and salinity (SSS) are linked to changes in North Atlantic Ocean circulation and North American hydroclimate. Although SST and SSS variability in the Gulf of Mexico are well understood on inter-annual and glacial-interglacial timescales, little is known about centennial scale variability in these sea surface parameters through the Holocene. We present here the first continuous multi-decadal resolution time series of SST and SSS spanning the entire Holocene from the Gulf of Mexico. This proxy reconstruction is based on paired measurements of Mg/Ca and δ18O in the planktic foraminifer, Globigerinoides ruber (white variety) in the Garrison Basin. Using these data, in combination with additional Gulf of Mexico SST and SSS records from the late Holocene, we explore linkages between North American precipitation patterns and ocean circulation on centennial timescales.

    The study aims to determine whether place of origin has an effect on Mexican American cardiovascular disease (CVD) risk on the South Texas Border. Although many studies have investigated the effect of immigration on Mexican American health, few have considered how region of origin may impact CVD risk. Subjects in the Cameron County Cohort Study were divided into 3 groups according to place of origin: Southern Mexico, Northern Mexico, and U.S. Border States. Descriptive statistics and regression analyses were conducted using CVD biomarkers and self-reported angina, stroke, and elevated blood pressure. Logistic regression revealed that subjects born in U.S. Border States and Northern Mexico states were significantly less likely to have high glucose levels (p < .05) than those born in Southern Mexico. Subjects born in Northern Mexico were less likely to have high triglycerides (p = .05). This study illustrates the importance of considering region of origin in studying the effect of immigration on Mexican American health beyond the standard: number of years in the United States.

    Mexico harbors great cultural and ethnic diversity, yet fine-scale patterns of human genome-wide variation from this region remain largely uncharacterized. We studied genomic variation within Mexico from over 1,000 individuals representing 20 indigenous and 11 mestizo populations. We found striking genetic stratification among indigenous populations within Mexico at varying degrees of geographic isolation. Some groups were as differentiated as Europeans are from East Asians. Pre-Columbian genetic substructure is recapitulated in the indigenous ancestry of admixed mestizo individuals across the country. Furthermore, two independently phenotyped cohorts of Mexicans and Mexican Americans showed a significant association between sub-continental ancestry and lung function. Thus, accounting for fine-scale ancestry patterns is critical for medical and population genetic studies within Mexico, in Mexican-descent populations, and likely in many other populations worldwide.

    We conducted a cross-sectional study among 1,717 children and adolescents of Mexican origin ages 5-19 years living in Mexico and Texas to explore the influence of country of birth and country of longest residence on their overweight and obesity status. Descriptive statistics were used to compare demographic and anthropometric characteristics of participants born and raised in Mexico (Mexicans), born in Mexico and raised in the United States (Mexican immigrants), and born and raised in the United States (Mexican-Americans). Univariate and multivariate nominal logistic regression was used to determine the demographic predictors of obesity adjusted by country of birth, country of residence, age, and gender. Almost half (48.8%) of the Mexican-Americans and 43.2% of the Mexican immigrants had body mass index at the 85th percentile or above, compared to only 29.3% of the Mexicans (P < .001). Thus, Mexican-Americans and Mexican immigrants were more likely to be obese than their Mexican peers [Mexican-Americans: odds ratio (OR) = 2.5 (95% confidence interval [CI] 1.8-3.4); Mexican immigrants: OR = 2.2 (95% CI 1.6-3.0)]. In addition, males were more likely than females to be obese [OR = 1.6 (95% CI 1.2-2.1)], and adolescents 15-19 years of age were less likely than their younger counterparts [OR = 0.5 (95% CI 0.4-0.7)] to be obese. The high prevalence of obesity among children of Mexican origin in the United States is of great concern and underscores the urgent need to develop and implement obesity preventive interventions targeting younger children of Mexican origin, especially newly arrived immigrant children. In addition, future obesity research should take into consideration the country of origin of the study population to develop more culturally specific obesity interventions.

    The predominately Hispanic U.S.-Mexico border population is at an elevated risk for drinking and associated problems due to the area’s low SES, poor services infrastructure, and drug-related violence. Among Mexican American residents, recent studies suggest this risk is particularly pronounced among younger age groups, and a key characteristic of this elevated risk involves crossing the border to drink in Mexico (where the legal drinking age is 18). However, few studies have compared the drinking behavior of U.S. residents who consume alcohol on the Mexico side of the border with those who do not. We address this gap in the present study. A multistage household probability sample of 1,307 Mexican American border residents was interviewed about their drinking and associated problems over the past year. The survey response rate was 67%. Among current drinkers who reported going to Mexico in the past 12 months (N = 468), 36.1% reported consuming alcohol in Mexico. Those who drank in Mexico reported significantly more drinks per week (12.8 versus 8.7, p < .05), were more likely to have binged (58.3% versus 35.4%, p < .001), and were more likely to report one or more alcohol problems (35.5% versus 19.5%, p < .01) than those who did not drink in Mexico. Among those who drank in Mexico, men reported significantly more drinks per day while in Mexico than women (6.2 versus 4.0, p < .001). Male gender and lower income were significant predictors of drinking in Mexico. These findings suggest that drinking in Mexico contributes to the heightened risk for drinking and associated problems seen in previous research among Mexican Americans living on the U.S.-Mexico border.

    2010-01-01

    The golden section has been said by many to be the most beautiful proportion. Fechner was the first to investigate it experimentally, and several late-nineteenth- and early-twentieth-century American psychologists followed up on his work. Among these were four prominent names: Lightner Witmer (1867-1956), Edward L. Thorndike (1874-1949), Robert S. Woodworth (1869-1962), and Robert M. Ogden (1877-1959). Why did such well-known psychologists bother with the golden section? In attempting to answer this question we discovered that the golden section was surprisingly well known during this period, not only in psychology but also in advertising and design. It would have been entirely congruent with their stature for prominent psychologists to take an interest in it.

    mtDNA sequence variation was examined in 60 Native Americans (Mixtecs from the Alta, Mixtecs from the Baja, Valley Zapotecs, and Highland Mixe) from southern Mexico by PCR amplification and high-resolution restriction endonuclease analysis. Four groups of mtDNA haplotypes (haplogroups A,B,C, and D) characterize Amerind populations. The comparison of their mtDNA variation with that observed in other populations from Mexico and Central America permits a clear distinction among the different Middle American tribes and raises questions about some of their linguistic affiliations. The males of these population samples were also analyzed for Y-chromosome RFLPs with the probes 49a, 49f, and 12f2. This analysis suggests that certain Y-chromosome haplotypes were brought from Asia during the colonization of the Americas, and a differential gene flow was introduced into Native American populations from European males and females. 31 refs., 4 figs., 5 tabs.

  3. Alcohol and suicide death among American Indians of New Mexico: 1980-1998.

    The relationship between alcohol use prior to suicide was explored among American Indian decedents in New Mexico for the years 1980 through 1998. The suicide data were collected from New Mexico Vital Statistics and toxicology reports from the New Mexico Office of the Medical Investigator and matched on a case-by-case basis. Detailed analyses were undertaken for all cases of resident New Mexico Indians from the Navajo, Pueblo, and Apache cultures. Alcohol was detected in 69% of all suicides of American Indians with some variance by major tribal cultural groups (range = 62.1% to 84.4%). This is higher than in suicides among the overall New Mexico population (44.3%). The mean blood alcohol concentration (BAC) of the drinking Indian decedents at suicide was 0.198 (+/- SD of .088). Mean BACs were high for both males (0.199) and females (0.180) who had been drinking. Over 90% of the Indian decedents who had been drinking had BACs greater than the legal intoxication level of 0.08. The Navajo had the lowest percentage of cases that were alcohol involved, and their mean BAC was lower than the other two cultural groups. Alcohol use for completed suicides also varied somewhat by age, sex, method of suicide, and place of occurrence, but very little by whether the decedent was an on or off reservation resident. Analyses indicated that alcohol use prior to suicide was significantly more associated with male suicides than for females, and it was negatively correlated for those who died by overdose and also those using other drugs at suicide. Otherwise, alcohol use did not significantly differentiate American Indian suicides by age, use of firearms, hanging, use of other methods, or residence, for the presence of alcohol was a factor very commonly associated with all of these variables. Heavy alcohol consumption is, therefore, an important factor in over two thirds of all completed suicides among the Indians of New Mexico.

    New Mexico has extraordinarily high injury mortality rates. To better characterize the injury problem in New Mexico, we calculated proportionate injury mortality and age-adjusted and age-specific injury mortality rates for the state's 3 major ethnic groups--American Indians, Hispanics, and non-Hispanic whites. According to death certificate data collected from 1958 to 1982 and US population census figures, age-adjusted mortality rates for total external causes varied widely between the sexes and among the ethnic groups. Males in each ethnic group consistently had higher average annual age-adjusted external mortality rates than females. Injury mortality rates for American Indians of both sexes were 2 to 3 times higher than those for the other New Mexico ethnic groups. Motor vehicle crashes were the leading cause of death from injury for all 3 groups. Homicide accounted for twice the proportion of injury death in Hispanic compared with non-Hispanic white males (12.5% and 6.1%, respectively), while the proportion of males dying of suicide was highest in non-Hispanic whites. Deaths from excessive cold and exposure were leading causes of injury mortality for American Indians, but these causes were not among the leading causes of injury mortality for Hispanics or non-Hispanic whites. We conclude that the minority populations in New Mexico are at high risk for injury-related death and that the major causes of injury mortality vary substantially in the state's predominant ethnic populations.

  7. Identity narratives by American and Canadian retirees in Mexico.

    Banks, Stephen P

    2004-12-01

    Ethnographic materials, including depth interviews and a video, are analyzed to better understand how expatriate retirees living in the Lake Chapala Riviera region of Jalisco, Mexico manage personal identities in retirement. Using concepts from narrative gerontology, this study demonstrates how expatriates' stories and descriptions of Mexicans and Mexican ways of life reflexively construct storytellers' identities and provide a logic for intercultural relationships. While the host population is characterized as happy, friendly, helpful, enterprising and polite, concurrent stories by the same narrators portray them also as untrustworthy, inaccessible, lazy and incompetent. A discourse analysis that extends Cavarero's narrative identity theory argues that these contrasting conceptions of the host culture and population are deployed so as to reflexively position expatriate retirees as interpersonally attractive, culturally tolerant and pragmatically adaptable. Implications for the subjective experience of international migrant retirees are drawn from the descriptive analysis.

    There is limited research on the effect of immigration on biological markers of nutrition among children of Mexican origin in the United States. The purpose of this cross-sectional study was to examine data from the Third National Health and Nutrition Examination Survey (NHANES III) (1988-1994), on a national and representative sample of 1559 Mexican American children, 4-16 years of age, and assess the associations of country of birth with serum concentrations of carotenoids, vitamin A, and vitamin E. In multiple regression analyses, Mexico-born Mexican American children had significantly higher serum concentrations of α-carotene, β-carotene, β-cryptoxanthin, lutein/zeaxanthin, vitamin A, and vitamin E than their counterparts who were born in the United States after adjustment for age, sex, poverty income ratio, level of education of family reference person, body mass index, total serum cholesterol, serum cotinine, total energy intake, and vitamin/mineral consumption. Our findings confirm evidence for a negative effect of immigration/acculturation on dietary quality in this population. These findings also suggest that immigrant Mexican families should be encouraged to maintain their consumption of fruits and vegetables. Prospective studies are needed to further assess the effects of immigration/acculturation on diet and other health outcomes in children of Mexican origin and immigrants.

    Increased social and economic integration across the US-Mexican borders has led to important new developments in public health. Lower levels of cardiovascular mortality have been observed among Mexican Americans (MAs) although few direct comparisons have been undertaken with Mexico. Using survey data in the respective countries we examined blood pressure (BP) levels, hypertension prevalence and patterns of awareness, treatment and control in Mexico and among MAs. A national representative sample of the adult population from Mexico collected in 2000 (N=49 294), and data on 8688 MA participants in the 1999-2004 National Health and Nutrition Examination survey from the United States were available for analysis. US-born MAs and those born in Mexico were analysed separately in the US data. Lack of direct standardization of methods between surveys necessitated statistical adjustment of BP values. Analyses were based on persons aged 25-64 in each country. Sex- and age-adjusted mean systolic/diastolic BPs were 122/80, 119/71 and 120/73 in Mexicans, immigrant MAs and US-born MAs, respectively. The prevalences of hypertension (BP > or = 140/90 or treatment) were 33, 17 and 22%. Hypertension control rates were 3.7, 32.1 and 37.9%, in the same groups. Awareness and treatment rates were 25 and 13% in Mexico and 54 and 46% among MAs in the United States, respectively. Hypertension appears to be more common in Mexico than among Mexican immigrants to the United States. Despite relatively low access to health insurance in the United States, hypertension control increased over the course of this migration.

  15. Mexico's conditional cash transfer programme increases cesarean section rates among the rural poor.

    PubMed

    Barber, Sarah L

    2010-08-01

    Caesarean section rates are increasing in Mexico and Latin America. This study evaluates the impact of a large-scale, conditional cash transfer programme in Mexico on caesarean section rates. The programme provides cash transfers to participating low income, rural households in Mexico conditional on accepting health care and nutrition supplements. The primary analyses uses retrospective reports from 979 women in poor rural communities participating in an effectiveness study and randomly assigned to incorporation into the programme in 1998 or 1999 across seven Mexican states. Using multivariate and instrumental variable analyses, we estimate the impact of the programme on caesarean sections and predict the adjusted mean rates by clinical setting. Programme participation is measured by beneficiary status, programme months and cash transfers. More than two-thirds of poor rural women delivered in a health facility. Beneficiary status is associated with a 5.1 percentage point increase in caesarean rates; this impact increases to 7.5 percentage points for beneficiaries enrolled in the programme for >or=6 months before delivery. Beneficiaries had significantly higher caesarean delivery rates in social security facilities (24.0 compared with 5.6% among non-beneficiaries) and in other government facilities (19.3 compared with 9.5%). The Oportunidades conditional cash transfer programme is associated with higher caesarean section rates in social security and government health facilities. This effect appears to be driven by the increases in disposable income from the cash transfer. These findings are relevant to other countries implementing conditional cash transfer programmes and health care requirements.

    mtDNA sequence variation was examined in 60 Native Americans (Mixtecs from the Alta, Mixtecs from the Baja, Valley Zapotecs, and Highland Mixe) from southern Mexico by PCR amplification and high-resolution restriction endonuclease analysis. Four groups of mtDNA haplotypes (haplogroups A, B, C, and D) characterize Amerind populations, but only three (haplogroups A, B, and C) were observed in these Mexican populations. The comparison of their mtDNA variation with that observed in other populations from Mexico and Central America permits a clear distinction among the different Middle American tribes and raises questions about some of their linguistic affiliations. The males of these population samples were also analyzed for Y-chromosome RFLPs with the probes 49a, 49f, and 12f2. This analysis suggests that certain Y-chromosome haplotypes were brought from Asia during the colonization of the Americas, and a differential gene flow was introduced into Native American populations from European males and females.

    In 2011, the senior authors were contacted by Ron Gardiner of Questa, and Village of Questa Mayor Esther Garcia, to discuss the existing and future groundwater supply for the Village of Questa. This meeting led to the development of a plan in 2013 to perform an integrated geologic, geophysical, and hydrogeologic investigation of the Questa area by the New Mexico Bureau of Geology & Mineral Resources (NMBG), the U.S. Geological Survey (USGS), and New Mexico Tech (NMT). The NMBG was responsible for the geologic map and geologic cross sections. The USGS was responsible for a detailed geophysical model to be incorporated into the NMBG products. NMT was responsible for providing a graduate student to develop a geochemical and groundwater flow model. This report represents the final products of the geologic and geophysical investigations conducted by the NMBG and USGS. The USGS final products have been incorporated directly into the geologic cross sections. The objective of the study was to characterize and interpret the shallow (to a depth of approximately 5,000 ft) three-dimensional geology and preliminary hydrogeology of the Questa area. The focus of this report is to compile existing geologic and geophysical data, integrate new geophysical data, and interpret these data to construct three, detailed geologic cross sections across the Questa area. These cross sections can be used by the Village of Questa to make decisions about municipal water-well development, and can be used in the future to help in the development of a conceptual model of groundwater flow for the Questa area. Attached to this report are a location map, a preliminary geologic map and unit descriptions, tables of water wells and springs used in the study, and three detailed hydrogeologic cross sections shown at two different vertical scales. The locations of the cross sections are shown on the index map of the cross section sheet.

    BACKGROUND This paper examines the prevalence, the symptom profile, and the drinking and sociodemographic predictors of current (past 12 month) DSM-IV alcohol abuse and dependence among Mexican Americans living along the U.S.-Mexico border and those living in metropolitan areas away from the border. METHODS Respondents in the non-border areas (primarily Houston and Los Angeles) constitute a multistage probability sample (N=1,288) of these areas, interviewed as part of the 2006 Hispanic Americans Baseline Alcohol Survey (HABLAS). Respondents in the border area (N=1,307) constitute a household probability sample of Mexican Americans living on the border. In both surveys, data were collected during computer assisted interviews conducted in respondents’ homes. The HABLAS and the border sample response rates were 76% and 67%, respectively. RESULTS Although bivariate analyses revealed no overall differences between border and non-border locations, (negative) age trends were more pronounced on the border for male abuse and for dependence among both genders. Among females aged 18–29, border residence was linked to significantly higher rates of dependence. In multivariable analyses, the prevalence of male abuse declined more rapidly with age on the border than off the border. Other unique predictors of male abuse were Jewish/other religion and weekly volume of alcohol consumption. Being married or out of the workforce, attaining a higher education, no religious preference, and weekly volume uniquely predicted female dependence. Age and weekly volume uniquely predicted male dependence. CONCLUSIONS The prevalence of alcohol use disorders among Mexican Americans on and off the U.S.-Mexico border largely mirrors previously documented patterns of alcohol consumption in these areas. For young Mexican-American women in particular, border residence is linked to heightened vulnerability to alcohol dependence. PMID:23278433

    Hepatitis A virus (HAV) remains a public health concern worldwide contributing to significant morbidity in developed and developing countries. This cross-sectional database study estimated the overall HAV seroprevalence and the seroprevalence by gender, age, region and socioeconomic status in Mexico. Between January and October 2010, serum samples collected during the National Health and Nutrition survey (ENSANUT 2006) were obtained from subjects aged 1–95 y. Subjects’ gender, age, geographical region and socioeconomic status were extracted from the survey and compiled into a subset database by the Mexican National Institute of Public Health. Anti-HAV antibodies were measured using a chemiluminescent immunoassay. A total of 3658 subjects were included in the according-to-protocol cohort. Overall, the HAV seroprevalence was 84.2%. The HAV seroprevalence rates were similar between females (86.1%) and males (82.2%). The percentage of subjects seropositive for anti-HAV antibodies was highest in adults aged ≥ 20 y (96.9%), followed by adolescents aged 10–19 y (80.1%) and lowest in children aged 1–9 y (45.0%) (p < 0.0001). Regionally, the highest HAV seroprevalence rate was observed in the South (88.8%) followed by Central and Northern Mexico and Mexico City (p = 0.02). The HAV seroprevalence was similar between subjects of high socioeconomic (90.1%) status and of low socioeconomic status (86.6%). This study confirms the intermediate HAV endemicity in Mexico. Cost-effectiveness studies are necessary to evaluate the inclusion of an effective hepatitis A vaccine from a population-based perspective in addition to continuous efforts to improve hygiene and sanitation that have a substantial impact on the disease burden.

    OBJECTIVES. The purposes of the study were to assess the potential impact of the North American Free Trade Agreement (NAFTA) on medical care in Mexico and to identify internal measures Mexico could take to increase the benefits and minimize the risks of free trade. METHODS. The dual nature of the health sector is examined; the Mexican, Canadian, and US health care systems are compared; and modes and consequences of international exchange of health services are analyzed. RESULTS. Four issues require immediate attention: accreditation of health care facilities, licensing and certification of professionals, technology assessment, and financial equity. CONCLUSIONS. NAFTA offers opportunities for positive developments in Mexico, provided risks can be anticipated and preventive measures can be taken to avoid negative impacts on the health system. Medical services, like other elements of the Mexican economy, must be modernized to respond to the demands of global competition. The Mexican National Academy of Medicine has recommended to the Mexican government (1) internal strengthening of the Mexican health care system to improve its ability to respond to the new conditions created by NAFTA and (2) a gradual process to facilitate equitable and mutually beneficial interactions among the three countries.

    American Trypanosomiasis (AT) is an infectious parasitic disease produced by the protozoa Trypanosoma cruzi (T. cruzi). Infection is acquired by vectorial via but can also be transmitted congenitally, by ingestion of an infected host, by transfusion with contaminated blood or transplant of organs from an infected donor. Currently, AT is widely distributed from the South of the United States to South America. In Mexico, the presence of the parasite has been reported throughout the country where several reservoirs such as dogs, opossums, rats and cats have been identified. Yucatan is in the south-east of Mexico where AT is endemic and has been reported since 1940s. There is little information about the role of pigs as reservoirs of T. cruzi. The frequency of specific antibodies against T. cruzi was determined in fattening pigs from Yucatan, Mexico. After sampling in the 3 main areas of pig production in the state, IgG ELISA and Western blot were performed to identify seropositive cases. Association of farm size, farm area and production system with infected pigs was evaluated. From 273 sampled pigs, 5.4% (n = 15) positive cases were found. No association with evaluated factors and infected pigs was found. Pigs are also reservoirs of T. cruzi in the studied area. These findings are considered important to improve vectorial control in the area in order to avoid the parasite infection in animal populations destined for human consumption and avoid further transmission to humans. © 2012 Blackwell Verlag GmbH.

    We report initial paleomagnetic and magnetostratigraphic results for one of the Cretaceous/Tertiary (K/T) boundary sections from northeastern Mexico. La Ceiba section is located in the Tampico-Mizantla carbonate basin, northeastern Puebla State. The section is characterized by three sedimentary clastic units, which have been described in detail in previous studies of K/T sections of northern Mexico. Its basal unit is formed by an alternation of calcareous reddish-greenish to gray shales, with calcareous clay layers. Unit II is 1.10-m thick and includes a shperulitic layer at the base and four sandstone layers. The top of the K/T sediments is marked by a clay layer and is covered by the Paleocene Velasco Formation. The Palaeocene is represented by 0.7-m dark brown-gray calcarenites with interbedded greenish-gray fine-grained material. Twenty-eight oriented cores were drilled from several beds in the K/T clastic units and the Paleocene sediments. All samples were measured in the laboratory (low-field magnetic susceptibility, NRM intensity and direction). Alternating field and thermal demagnetizations were used to investigate on the vectorial composition and stability of remanences. The magnetic mineralogy was further studied by imparting samples an isothermal remanent magnetization (IRM) and measuring magnetic hysteresis parameters using the MicroMag system. Well-defined characteristic magnetizations were isolated and used to construct a polarity stratigraphy for the K/T section. The clastic unit II and Paleocene sediments present a reverse polarity magnetization, which correlates with the expected polarity within 29r chron that includes the K/T boundary.

    This true-color image of Mexico was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. In areal extent, Mexico is the third largest country on the continent of North America (not counting Greenland, which is a province of Denmark), comprised of almost 2 million square kilometers (756,000 square miles) of land. Home to roughly 100 million people, Mexico is second only to the United States in population, making it the world's largest Spanish-speaking nation. To the north, Mexico shares its border with the United States-a line that runs some 3,100 kilometers (1,900 miles) east to west. About half of this border is defined by the Rio Grande River, which runs southeast to the Gulf of Mexico (partially obscured by clouds in this image) and marks the dividing line between Texas and Mexico. Toward the upper left (northwest) corner of this image is the Baja California peninsula, which provides the western land boundary for the Gulf of California. Toward the northwestern side of the Mexican mainland, you can see the Sierra Madre Occidental Mountains (brownish pixels) running southeast toward Lake Chapala and the city of Guadalajara. About 400 km (250 miles) east and slightly south of Lake Chapala is the capital, Mexico City. Extending northward from Mexico City is the Sierra Madre Oriental Mountains, the irregular line of brownish pixels that seem to frame the western edges of the bright white cumulus clouds in this image. Between these two large mountain ranges is a large, relatively dry highland region. To the south, Mexico shares borders with Guatemala and Belize, both of which are located south of Mexico's Yucatan Peninsula.

    The prevalence of diagnosed diabetes among American Indians in New Mexico with varied genetic and cultural backgrounds is reported. Utilizing community-based registries, the prevalence in persons ages 35 years and older ranged from 9.8 percent among Jicarilla Apache Indians to 28.2 percent among Zuni Indians. All rates were significantly higher than the U.S. rate of 5.3 percent for the same age group. In addition, in three of the five tribal groups examined, the rates of diagnosed diabetes in Indians less than 35 years of age (range from 0.5 percent to 1.3 percent) were significantly higher than the U.S. rate of 0.4 percent for the same age group. The prevalence rates of diagnosed diabetes found in this study of American Indians in New Mexico were intermediate between those for the United States as a whole and the Pima Indians of southern Arizona. Reasons for the variations and the relative contribution of obesity, fitness, or genetic risk in the development of diabetes need further study. PMID:2511603

  12. Mexican American Men's Experience of Living With Tuberculosis on the U.S.-Mexico Border.

    The Texas-Mexico border incidence rate of tuberculosis (TB) is 10 times the rate of TB in the United States. Additionally, this area is plagued by antibiotic-resistant TB at a rate that is 70% higher among those living along the border than among nonborder residents. Both the high rate of TB and the emergence of drug-resistant TB increases the importance of controlling TB along the U.S.-Mexico border. Men have higher rates of TB than women, which can be attributed to biological differences and increased environmental exposure. The purpose of this article is to describe the experience of TB for Mexican American men living on the Texas-Mexico border. This a qualitative descriptive study, using participants from a larger study. A purposeful sample was recruited through two south Texas TB clinics. Interviews were audio recorded, transcribed, and translated into English. Data analysis consisted of line-by-line coding, labeling, organizing, and discovering common codes to describe participants' experience of TB and TB treatment. The participants include 13 Mexican American men. Ages ranged from 22 to 76 years. Only one participant was employed during treatment. Years of education ranged from no school to an associate's degree. Five themes were discovered: misinformation, delayed diagnosis, stigma, depression, and loss of community. Participants without social support were further isolated and felt a greater burden of treatment. Two participants contemplated suicide and two others told their families to leave them because they were a burden and infectious. The burden of treatment on the patient is great, especially for Hispanic men.

    The purpose of this study was to assess whether nutrients offered to border Mexican-American preschool children met the Recommended Dietary Allowances. Nutrient contents of two dietary patterns were examined in this study, one composed exclusively of home foods and one containing a combination of both home and school foods. The sample consisted of 198 Mexican-American preschoolers living on the Texas-Mexico border, who were recruited using a convenience sampling technique. A self-administered, precoded 24-hour recall questionnaire was used. Nutrient values of home foods were collected during a weekend day, and nutrient values containing a combination of both home and school foods were collected during a weekday. Fisher's exact test or chi2 test and t test were used for analyses. Mean nutrient contents of foods provided to the border Mexican-American children exceeded recommendations for total energy (P<0.001), total fat (P<0.001), saturated fat (P<0.001), carbohydrates (P<0.001), protein (P<0.001), sodium (P<0.001), and niacin (P<0.001). Foods offered were also significantly insufficient in fiber (P<0.001), vitamin A (P<0.001), and potassium (P<0.001). Nutrition interventions targeting low-income border Mexican-American families should emphasize the need and importance of providing children with diets that meet the Recommended Dietary Allowances.

    Objectives. We assessed the association between birthplace, residence, or years in the United States and actual weight (body mass index), perceived weight accuracy, or provider screens for overweight or obesity among Mexican immigrant women. Methods. We used linked data from Health and Nutrition Examination Survey waves 2001–2006 and 2006 National Mexican Health and Nutrition Survey to compare 513 immigrants with 9527 women in Mexico and 342 US-born Mexican American women. Results. Immigrants were more likely than women in Mexico to be obese and to perceive themselves as overweight or obese after adjustment for confounders. Recent immigrants had similar weight-related outcomes as women in Mexico. Immigrants were less likely to be obese than were US-born Mexican Americans. Within the overweight or obese population, reported provider screens were higher among immigrants than among women in Mexico, but lower than among US-born Mexican Americans. US residency of at least 5 years but less than 20 years and reporting insufficient provider screens elevated obesity risk. Conclusions. Mexican-origin women in the United States and Mexico are at risk for overweight and obesity. We found no evidence of a “healthy immigrant” effect. PMID:23865649

    1986-07-01

    In contrast to previous interpretations of the Rosario Formation in other parts of Baja California, a stratigraphic section 6 km north of Ensenada, Baja California, Mexico, contains evidences for deposition in shallow waters during a regressive event in a steep slope basin. Among the sedimentary evidence, the section shows a coarse, shoaling-upward sequence, with high-angle cross-stratification and planar bed lamination. Load structures with a westward orientation were found only at the base. The fossils assemblages support the same shoaling-upward interpretation as the sedimentary evidence, with ammonoids and deposit feeder trace fossils (such as Chondrites) at the bottom to mollusks and suspension feeder trace fossils (such as Scolicia and Ophiomorpha, characteristic of shallower waters) at the top. This sedimentologic and paleontologic evidence suggests nearshore to beach coastal deposits. The contact between the section and a discontinuous thin limestone bed at the top of the section shows an unconformity. The absence of well-preserved fossils makes this limestone difficult to date, but the lithology is similar to that of Paleocene Sepultura Formation limestones.

    To describe the trend of cesarean section practice in Mexico, and its association with women's sociodemographic and reproductive characteristics. Based on the 2000, 2006 and 2012 National Health Surveys, information on c-section was analyzed. A multivariate logistic regression model was used in 2012. A 50.3% increase in the use of c-section was observed nationally from 2000 to 2012. Women more likely to undergo a c-section include those whose delivery care takes place in the private sector (OR=2.84, 95%CI:2.15-3.74). When associating women's age and parity, the greatest risks are observed among primiparous women between 12 and 19 years of age, and those aged 35 years and more (OR=6.02, 95%CI:1.24-29.26 and OR=5.20, 95%CI:2.41-11.21, respectively). Some recommendations to revert the increase of this clinical practice, especially when there is no full justification for its realization, are proposed.

    To compare cardiovascular disease (CVD) risk factors in a cohort of Mexican health workers with representative samples of US-born and Mexico-born Mexican-Americans living in the US. Data were obtained from the Mexican Health Worker Cohort Study (MHWCS) in Mexico and the National Health and Nutrition Examination Survey (NHANES) IV 1999-2006 in the US. Regression analyses were used to investigate CVD risk factors. In adjusted analyses, NHANES participants were more likely than MHWCS participants to have hypertension, high total cholesterol, diabetes, obesity, and abdominal obesity, and were less likely to have low HDL cholesterol and smoke. Less-educated men and women were more likely to have low HDL cholesterol, obesity, and abdominal obesity. In this binational study, men and women enrolled in the MHWCS appear to have fewer CVD risk factors than US-born and Mexico-born Mexican-American men and women living in the US.

    Pediatric melanoma rates are increasing nationally. Our purpose was to determine the incidence of melanoma in New Mexico's (NM's) American Indian, Hispanic, and non-Hispanic white children. A retrospective review (1981 to 2009) of the NM Tumor Registry was conducted. Melanomas diagnosed in children <19 years of age were identified. Average annual age-adjusted incidence rates per million were calculated. Sixty-four cases were identified. Rates per million were 7.4 for non-Hispanic whites, 2.1 for Hispanics, and 3.3 for American Indians. Fifty-nine percent were women. Fifty-five (86%) cases were localized, 6 (9%) were regional, and 1 (3%) case was metastatic. Majority of cases (49/64; 77%) occurred in children >14 years of age. American Indians presented with thicker melanomas as compared to whites and Hispanics. Incidence rates for pediatric melanoma in NM are highest for non-Hispanic whites. Distant metastasis is uncommon. Melanoma in children is rare, but practitioners must be aware of its occurrence for prompt diagnosis and treatment. Copyright © 2014 Elsevier Inc.

    Examination of seismic data from over 1000 MMS geohazard reports and core logs of 1670 foundation boreholes (drilled to an average subbottom depth of 125 m), has revealed that gassy sediment sections are most abundant near the Mississippi River delta, in buried stream channels eroded during the early and late Wisconsinan, and in Miocene and Pliocene-Pleistocene depocenters on the shelf and upper slope. Of all the boreholes that we examined, 1158 (68%) contained indications of gassy sediments. The {open_quotes}average{close_quotes} Mississippi River delta related gassy sediment section occurs at a water depth of 53 m; the top of the section lies at a subbottom depth of 10 m; its thickness is 12 m; and the sediment water content is 45%, with liquid and plastic limits of 73% and 24%, respectively. For the nondeltaic areas of the continental shelf (areas west of 90{degrees}W), the average gassy sediment section lies at a water depth of 37 m, its depth below the sea floor is 37 m, its thickness is 8 m, the water content is 40%, and the liquid and plastic limits are 68 and 27%. For the upper continental slope in the northwestern Gulf of Mexico, the average gassy sediment section is found at a water depth of 265 m, is 25 m below the sea floor, and has a thickness of 60 in, a water content of 40%, and a liquid and plastic limit of 62 and 32%. The median areal extent of gassy sediment sections within the entire shelf and upper slope of the northwestern Gulf area ranges from 238 to 546 m. Although large patches of gassy sediments exist, with some exceeding 10 km in size, most are less than 500 m.

    We tracked the unintentional injury death disparity between American Indians/Alaska Natives and non-American Indians/Alaska Natives in New Mexico, 1980 to 2009. We calculated age-adjusted rates and rate ratios for unintentional injury deaths and their external causes among American Indians/Alaska Natives and non-American Indians/Alaska Natives. We tested trend significance with the Mann-Kendall test. The unintentional injury death rate ratio of American Indians/Alaska Natives to non-American Indians/Alaska Natives declined from 2.9 in 1980-1982 to 1.5 in 2007-2009. The rate among American Indians/Alaska Natives decreased 47.2% from 1980-1982 to 1995-1997. Among non-American Indians/Alaska Natives, the rate declined 25.3% from 1980-1982 to 1992-1994, then increased 31.9% from 1992-1994 to 2007-2009. The motor vehicle traffic and pedestrian death rates decreased 57.8% and 74.6%, respectively, among American Indians/Alaska Natives from 1980-1982 to 2007-2009. The unintentional injury death rate disparity decreased substantially from 1980-1982 to 2007-2009 largely because of the decrease in motor vehicle crash and pedestrian death rates among American Indians/Alaska Natives and the increase in the poisoning death rate among non-American Indians/Alaska Natives.

    This is a case study about an 87-year-old Mexican American partera and her stories about her life and practice on the Texas-Mexico border from the 1930s until 1995. These stories describe strong and competent women who rode horses to remote areas to help with many deliveries of babies throughout their lives. Sra. B, the lay midwife agreed to be interviewed so that her work could be shared with others. The stories discussed told part of what she lived. These stories included clinical pearls that told about how to use "a few drops of oregano . . . and salt," and how to handle situations in which "the Lord was the only one who could help us," among others. These interviews tell part of the story about how Sra. B learned, lived, and practiced as a partera and how she is remembered by the families throughout the area.

    The qualitative study described in this article investigated perceptions about environmental factors influencing physical activity (PA) among children from underserved neighborhoods known as colonias in the U.S.-Mexico border. Ten focus groups were conducted with 67 Mexican-American colonia children ages 8 to 13 living in one of the poorest border counties in the U.S. Analyses indicated that PA among children was influenced by neighborhood characteristics, including litter, speeding cars, unleashed dogs, and dark streets. The children also underlined intrapersonal and social environmental factors. Findings may inform policy makers and public health professionals about ways to promote PA among underserved children through urban planning and programs focusing on PA-supportive infrastructure, neighborhood safety, and family- and home-based physical activities.

    Background: Underdiagnosis of chronic obstructive pulmonary disease (COPD) in primary care can be improved by a more efficient screening strategy. Aims: To evaluate a three-step method of screening for COPD consisting of an initial short questionnaire followed by measurement of forced expiratory volume in 1s/forced expiratory volume in 6s (FEV1/FEV6) using an inexpensive pocket spirometer in those with high risk, and diagnostic quality spirometry in those with a low FEV1/FEV6. Methods: We analysed two related Mexico City cross-sectional samples. The 2003 Mexico City PLATINO survey (n=542) was used to develop a short questionnaire to determine the risk of COPD and a 2010 survey (n=737) additionally used a pocket spirometer. The discriminatory power of the two instruments was assessed with receiver operator characteristic (ROC) curves using three COPD definitions. Results: The developed COPD scale included two variables from a simple questionnaire and, in ROC analysis, an area under the curve (AUC) between 0.64 and 0.77 was found to detect COPD. The pocket spirometer had an AUC between 0.85 and 0.88 to detect COPD. Using the COPD scale as a first screening step excluded 35–48% of the total population from further testing at the cost of not detecting 8–18% of those with COPD. Using the pocket spirometer and sending those with a FEV1/FEV6<0.80 for diagnostic quality spirometry is very efficient, and substantially improved the positive predictive value at the cost of not detecting one-third of COPD cases. Conclusions: A three-step screening strategy for COPD substantially reduces the need for spirometry testing when only a COPD scale is used for screening. PMID:24841708

    This guide was prepared for the field trip to the KT elastic sequence of northeastern Mexico, 5-8 February 1994, in conjunction with the Conference on New Developments Regarding the KT Event and Other Catastrophes in Earth History, held in Houston, Texas. The four-day excursion offers an invaluable opportunity to visit three key outcrops: Arroyo El Mimbral, La Lajilla, and El Pinon. These and other outcrops of this sequence have recently been interpreted as tsunami deposits produced by the meteorite impact event that produced the 200 to 300-km Chicxulub basin in Yucatan, and distributed ejecta around the world approximately 65 m.y. ago that today is recorded as a thin clay layer found at the K/T boundary. The impact tsunami interpretation for these rocks has not gone unchallenged, and others examining the outcrops arrive at quite different conclusions: not tsunami deposits but turbidites; not KT at all but 'upper Cretaceous.' Indeed, it is in hopes of resolving this debate through field discussion, outcrop evaluation, and sampling that led the organizers of the conference to sanction this field trip. This field guide provides participants with background information on the KT clastic sequence outcrops and is divided into two sections. The first section provides regional and logistical context for the outcrops and a description of the clastic sequence. The second section presents three representative interpretations of the outcrops by their advocates. There is clearly no way that these models can be reconciled and so two, if not all three, must be fundamentally wrong. Readers of this guide should keep in mind that many basic outcrop observations that these models are based upon remain unresolved. While great measures were taken to ensure that the information in the description section was as objective as possible, many observations are rooted in interpretations and the emphasis placed on certain observations depends to some degree upon the perspective of the author.

    This cross sectional study aims to determine the effects of gender and parental perception of safety at school on children's physical activity (PA) levels. Parents of school aged Mexican children residing in Guadalajara, Mexico City, and Puerto Vallarta, completed surveys about their children's PA measures. The physical activity indicators were evaluated using linear and logistical regression models. Analysis did not indicate that gender moderated the relationship between parental perception of safety and PA measures, but significant gender issues exist with girls participating less than boys in the three measures of PA in this study (p<0.001). Results suggest the need for additional interventions promoting physical activity in girls in Mexico.

    Abstract Two new species of Solanum section Crinitum are described here. Solanum falciforme Farruggia, sp. nov., closely resembles Solanum crinitum and Solanum lycocarpum, but differs by the presence of falcate trichomes on the young growth. It is endemic to the cerrado and adjacent woodlands of Distrito Federal, Bahia, Goiás and Minas Gerais, Brazil. The other species, Solanum pseudosycophanta Farruggia, sp.nov., has close affinities to Solanum sycophanta butdiffers from the latter in having prominent long-stalked stellate hairs along the stem, calyx, petiole and the adaxial surface of the leaf, in contrast to Solanum sycophanta which is glabrous or pubescent with sessile to short-stalked multangulate hairs. This species is narrowly distributed in tropical montane forests of northern Peru and southern Ecuador. PMID:22171169

    I have created and applied diverse methods in public outreach at National Autonomous Univerisity of Mexico (UNAM) since 2001.A student-led volunteer astronomical club has been created, the biggest in Mexico. We serve over 10,000 people per year. We have created public outreach activities for the general audience: archeo-astronomical outings, scientific movie debates, conferences, courses, public telescope viewings. We have also worked with juvenile delinquents to offer them scientific opportunities when released from jail.I've also created and worked the social media for the Institute of Astronomy UNAM, which is currently the biggest social media site on astronomy in Spanish in the world. I've created and organized a mass photo exhibition (over 1 million people served) for the Institute of Astronomy, UNAM which was citizen-funded through an online platform, the first of its kind in the country. Together with my colleages, we created workshops on astronomy for children with the Mexican's government funding.I've participated in several radio and television programs/capsules designed to bring astronomy to the general audience, one in particular ("Astrophysics for Dummies") was very successful in nation-wide Mexican radio.I am currently applying all experiences to develop a new public outreach project on astronomy for the University of California - Riverside and its on-campus and surrounding Latin American communities. We are offering new workshops for blind and deaf children. We want to integrate the Latino community to our outreach activities and offer science in their language in a simple and entertaining fashion. We have also successfully applied astrophotography as a course which brings social-science and arts undergraduate students into natural sciences.Sharing experiences, success and failure stories will help new and experienced educators and public outreach professionals learn and better from past experiences.

    Introduction: Leptospirosis is a zoonotic disease affecting mainly to low income human population. Acute leptospiral infection during pregnancy has been associated with spontaneous abortion and fetal death during the first trimester and the abortion may occur as consequence of systemic failure. Objective: To estimate the frequency of Leptospira interrogans infection in women with spontaneous abortion in the state of Yucatan, Mexico. Methods: A cross sectional study on women with spontaneous abortion was conducted. Serum samples were tested for Leptospirosis by the microaglutination test, to estimate the frequency of the infecting serovar. The indirect ELISA IgM was used to detect recent infection by L. interrogans. DNA was extracted from paraffin-embedded tissue of placenta for PCR detection of L. interrogans. Results: Overall frequency of infection with L. interrogans in the 81 women with abortion was 13.6%. Five of the 12 serovars evaluated were found and included. Two of the 11 women with abortion and positive to microaglutination test were also positive to the ELISA IgM test. None samples were positive for PCR Leptospira diagnosis. Conclusion: two women could be associated with spontaneous abortion due to leptospirosis, because they showed antibodies against L. interrogans in the microaglutination test and ELISA IgM assays. Differences between regions were found with respect to the prevalences of lesptospirosis. PMID:27226658

    Background This paper examines differences in drinking and binge drinking between Mexican Americans living along the U.S.-Mexico border and those living in two metropolitan areas away from the border (Houston, Texas, and Los Angeles, California). Methods Respondents in the non-border area (Houston and Los Angeles) constitute a multistage probability sample (N=1,288) who were interviewed as part of the 2006 Hispanic Americans Baseline Alcohol Survey (HABLAS). Respondents in the border area (N=1,307) constitute a household probability sample of Mexican Americans living on the U.S.-Mexico border. In both surveys, data were collected during computer assisted interviews conducted in respondents’ homes. The HABLAS and the border sample response rates were 76% and 67%, respectively. Results There were no differences between border and non-border Mexican American men in the proportion of drinkers, the proportion who binge drink at least once a year and volume of alcohol consumption. However, within each location, there were significant differences in drinking by age, indicating that younger men drank more than men who were older. Border women showed significant differences across age groups in the proportion of drinkers, in binge drinking and volume of alcohol consumption, which were not seen among non-border women. Conclusions Women’s drinking seems to be more affected than men’s by their residence on or off the U.S.-Mexico border. This is seen most clearly among young women 18–29 years old and it is associated with an increased proportion of drinkers, a higher volume of drinking and an increased proportion of women who report binge drinking. Increased drinking in this group of younger women seems to be associated with drinking in Mexico. PMID:22017228

    Many studies provide evidence relating lower human arsenic (As) methylation efficiency, represented by high percent urinary monomethylarsonic acid (MMA(V)), with several As-induced diseases, possibly due to the fact that MMA(V) serves as a proxy for MMA(III), the most toxic As metabolite. Some epidemiological studies suggested that indigenous Americans (AME) methylate As more efficiently; however, data supporting this have been equivocal. The aim of this study was to characterize the association between AME ancestry and As methylation efficiency using a panel of ancestry informative genetic markers to determine individual ancestry proportions in an admixed population (composed of two or more isolated ancestral populations) of 746 individuals environmentally exposed to As in northwest Mexico. Total urinary As (TAs) mean and range were 170.4 and 2.3-1053.5 μg/L, while percent AME (%AME) mean and range were 72.4 and 23-100. Adjusted (gender, age, AS3MT 7388/M287T haplotypes, body mass index [BMI], and TAs) multiple regression model showed that higher AME ancestry is significantly associated with lower percentage of urinary As excreted as MMA(V) (%uMMA) in this population (p < .01). Data also demonstrated a significant interaction between BMI and gender, indicating negative association between BMI and %uMMA, stronger in women than men (p < .01). Moreover, age and the AS3MT variants 7388 (intronic) and M287T (nonsynonymous) were also significantly associated with As methylation efficiency (p < .01). This study highlights the importance of BMI and indigenous American ancestry in some of the observed variability in As methylation efficiency, underscoring the need to be considered in epidemiology studies, particularly those carried out in admixed populations.

    Central America (CA), from Guatemala to Panama, has been struck by at least 52 tsunamis between 1539 and 2013, and in the extended region from Mexico to northern Peru (denoted as ECA, Extended Central America in this paper) the number of recorded tsunamis in the same time span is more than 100, most of which were triggered by earthquakes located in the Middle American Trench that runs parallel to the Pacific coast. The most severe event in the catalogue is the tsunami that occurred on 2 September 1992 off Nicaragua, with run-up measured in the range of 5-10 m in several places along the Nicaraguan coast. The aim of this paper is to assess the tsunami hazard on the Pacific coast of this extended region, and to this purpose a hybrid probabilistic-deterministic analysis is performed, that is adequate for tsunamis generated by earthquakes. More specifically, the probabilistic approach is used to compute the Gutenberg-Richter coefficients of the main seismic tsunamigenic zones of the area and to estimate the annual rate of occurrence of tsunamigenic earthquakes and their corresponding return period. The output of the probabilistic part of the method is taken as input by the deterministic part, which is applied to calculate the tsunami run-up distribution along the coast.

    Ten cases of echinococcosis diagnosed in American Indians in Arizona and New Mexico between 1972 and 1975 were investigated as part of a regional epidemiologic study. Patients were visited at home to discover factors associated with local parasite transmission, to detect possible additional cases among family members, and to perform diagnostic tests on dogs. Six patients were Navajo, 2 Zuni, and 2 Santo Domingo Indians. An additional case in a Navajo man was detected by serologic testing of patients' family members; this was the 20th case diagnosed in the region since 1965. Dogs owned by three of the Navajo patients were infected with Echinococcus granulosus. Arecoline-purge testing of 110 dogs in the Zuni pueblo demonstrated echinococcosis in a single stray dog. The findings at slaughter of Navajo-owned sheep indicate that the infection is enzootic in this intermediate host. The epidemiologic findings suggest that humans were infected from dogs which contracted their infections from two sources. The first was sheep raised locally in rural areas of the Navajo Reservation where the infection is enzootic in the dog-sheep cycle; transmission was apparently facilitated by the widespread practice of home butchering. A second source of human infection was dogs which became infected by eating viscera of sheep of off-reservation origin; these sheep were purchased and butchered by individual families in urban areas of the Navajo Reservation and in the Zuni and Santo Domingo pueblos.

    To determine the frequency and perceptions of herbal medicine use among Hmong Americans. Cross-sectional telephone survey. Sacramento, California Hmong community. Out of 118 subjects reached, 77 (65.3 %) reported lifetime use of herbal medicines. A majority of respondents agreed that herbal medicines were able to treat the body as a whole. Respondents felt that a leaflet of information indicating uses/side effects would be important to include for herbal medicines. Herbal medicine use was commonly reported among Hmong Americans. Thus, health care providers should be encouraged to discuss these alternative medicines with their Hmong American patients.

    Background Examining the association between social inequality and health is not new. However, there is little empirical evidence of this association in the Latin American literature, much less from the Mexican scholars. Its research, including the one conducted in Mexico, has mostly followed a theoretical approach and has not been able to provide strong empirical evidence of their important theoretical and conceptual contributions, mainly because reliable, complete and valid data are unavailable. Methods To empirically examine the gradient effect of social class on self-rated health in Mexico, a secondary cross-sectional mixed-level analysis was designed. Using individual level data from the Second National Health Survey (ENSA II), social class categories were specified following a stratification approach according to the occupation and education indicators available from ENSA II. Two types of categories were made, one for t urban and one for the rural labor force. Two indicators of perceived health status were used as health outcomes: self-assessed health and reported morbidity. Furthermore, the marginality index, an indicator of relative deprivation was used to examine its contextual effect at the state and regional level. The analysis was conducted using logistic multivariate models. Results The cross-sectional analysis showed a gradient effect of social class for good assessed-health. Relative to the low urban class, the odds ratio (OR) for a good perception of health for individuals belonging to the high urban class was 2.9 (95% confidence interval: 2.1–3.9). The OR for the middle high class was 2.8 (95% confidence interval: 2.4–3.4), while the OR for the middle low class was 1.8 (95% confidence interval: 1.6–2.1). However, for the rural labour force an OR of 1.5 was only significant between the high class who considered their health as good relative to the low class (95% confidence interval: 1.02–2.2). At the aggregate level, the results also showed

    Abstract Objective To describe causes of maternal mortality in Mexico over eight years, with particular attention to indirect obstetric deaths and socioeconomic disparities. Methods We conducted a repeated cross-sectional study using the 2006–2013 Búsqueda intencionada y reclasificación de muertes maternas (BIRMM) data set. We used frequencies to describe new cases, cause distributions and the reclassification of maternal mortality cases by the BIRMM process. We used statistical tests to analyse differences in sociodemographic characteristics between direct and indirect deaths and differences in the proportion of overall direct and indirect deaths, by year and by municipality poverty level. Findings A total of 9043 maternal deaths were subjected to the review process. There was a 13% increase (from 7829 to 9043) in overall identified maternal deaths and a threefold increase in the proportion of maternal deaths classified as late maternal deaths (from 2.1% to 6.9%). Over the study period direct obstetric deaths declined, while there was no change in deaths from indirect obstetric causes. Direct deaths were concentrated in women who lived in the poorest municipalities. When compared to those dying of direct causes, women dying of indirect causes had fewer pregnancies and were slightly younger, better educated and more likely to live in wealthier municipalities. Conclusion The BIRMM is one approach to correct maternal death statistics in settings with poor resources. The approach could help the health system to rethink its strategy to reduce maternal deaths from indirect obstetric causes, including prevention of unwanted pregnancies and improvement of antenatal and post-obstetric care.

    Abstract Objective To propose an antenatal care classification for measuring the continuum of health care based on the concept of adequacy: timeliness of entry into antenatal care, number of antenatal care visits and key processes of care. Methods In a cross-sectional, retrospective study we used data from the Mexican National Health and Nutrition Survey (ENSANUT) in 2012. This contained self-reported information about antenatal care use by 6494 women during their last pregnancy ending in live birth. Antenatal care was considered to be adequate if a woman attended her first visit during the first trimester of pregnancy, made a minimum of four antenatal care visits and underwent at least seven of the eight recommended procedures during visits. We used multivariate ordinal logistic regression to identify correlates of adequate antenatal care and predicted coverage. Findings Based on a population-weighted sample of 9 052 044, 98.4% of women received antenatal care during their last pregnancy, but only 71.5% (95% confidence interval, CI: 69.7 to 73.2) received maternal health care classified as adequate. Significant geographic differences in coverage of care were identified among states. The probability of receiving adequate antenatal care was higher among women of higher socioeconomic status, with more years of schooling and with health insurance. Conclusion While basic antenatal care coverage is high in Mexico, adequate care remains low. Efforts by health systems, governments and researchers to measure and improve antenatal care should adopt a more rigorous definition of care to include important elements of quality such as continuity and processes of care.

    Objectives We determined the seroprevalence and correlates of Toxoplasma gondii infection in pregnant women in Aguascalientes City, Mexico. Design A cross-sectional survey. Setting Pregnant women were enrolled in the central Mexican city of Aguascalientes. Participants We studied 338 pregnant women who attended prenatal care in 3 public health centres. Primary and secondary outcome measures Women were examined for IgG/IgM antibodies to T. gondii by using commercially available enzyme immunoassays, and an avidity test. Multiple analyses were used to determine the association of T. gondii seropositivity with the characteristics of the pregnant women. Results Of the 338 pregnant women studied, 21 (6.2%) had IgG antibodies to T. gondii, and 1 (4.8%) of them was also positive for IgM antibodies to T. gondii. Avidity of IgG antibodies to T. gondii was high in the IgM-positive sample. Logistic regression analysis of sociodemographic, behavioural and housing variables showed that T. gondii seropositivity was associated with white ethnicity (OR=149.4; 95% CI 10.8 to 2054.1; p<0.01), not washing hands before eating (OR=6.41; 95% CI 1.73 to 23.6; p=0.005) and use of latrine (OR=37.6; 95% CI 4.63 to 306.31; p=0.001). Conclusions Results demonstrate that pregnant women in Aguascalientes City have a low seroprevalence of T. gondii infection. However, this low prevalence indicates that most pregnant women are at risk for a primary infection. Factors associated with T. gondii exposure found in this study, including food hygiene, may be useful to determine preventive measures against T. gondii infection and its sequelae. PMID:27371556

    This paper examines alcohol-related social problems among Mexican Americans living along the U.S.-Mexico border and in non-border areas. Interviews were conducted among Mexican Americans in the border regions of California, Arizona, New Mexico, and Texas (N=1307). Non-border respondents were interviewed primarily in Houston and Los Angeles (N=1288) as part of the Hispanic Americans Baseline Alcohol Survey (HABLAS). Both the border and HABLAS surveys employed multistage cluster sample designs (response rates were 67% and 76%, respectively). In the bivariate analysis, there were no significant differences between border and non-border areas in the proportion of those with one or more social problem. In non-border areas, the prevalence of alcohol problems did not differ significantly by age. However, along the border the prevalence of alcohol problems was significantly different across age groups, with 18 to 29year old men and women having the highest prevalence. The final models showed no residence effect on problem likelihood. Drinking was strongly associated with problems. Although young border residents had higher problem prevalence rates than older residents, the logistic regression models showed no effect of border residence on the likelihood of problems, indicating that problems are due to alcohol consumption, not the border environment. The border, however, did appear to influence more drinking among young people. Regardless of residence, alcohol treatment and preventive interventions tailored to Mexican Americans are essential and special attention should be focused on younger individuals near the border.

    2007-05-01

    We report results of a micropaleontological and magnetostratigraphic study of the La Ceiba section that spans the K/T boundary. La Ceiba is located in central Mexico (20o 19.8' N, 97o 41.0' W) within the Tampico-Mizantla basin. The K/T boundary is marked by a clastic unit of about one-meter thickness intercalated between the carbonate hemipelagic marls of the Cretaceous Mendez Formation and the Paleocene Velasco Formation. The clastic unit can be divided into four sub-units, according to their texture and architectural characteristics following Arenillas et al. (2002). The basal sub-unit is formed by calcareous marls and is rich in shocked quartz and millimeter size spherules with microtektites and bioclasts of shallow water origin. The second sub-unit is formed by medium-grained sandstones, with clasts and quartz fragments, feldspars, metamorphic and calcareous fragments and re-worked benthic and planktic foraminifera. The third sub-unit is composed by a single body of medium- to fine-grained sandstones with tabular geometry. In this sub-unit, cross- and parallel-lamination trough cross-stratification, current ripples and climbing ripples have been observed. The top sub-unit is a tabular body of fine-grained sandstones, showing parallel-lamination and low-angle cross-lamination, with asymmetric ripples and burrow traces to the top. For the paleontologic and paleomagnetic study we collected twenty-five oriented samples across the section. We measured the low-field susceptibility, intensity and direction of the NRM. The vectorial composition and stability of NRM were analyzed by progressive thermal and alternating field demagnetization. Vectorial orthogonal diagrams and vector subtraction and principal component analysis were used to determine the characteristic magnetization and secondary components for each sample. The characteristic NRM negative inclination and southward declination in the K/T clastic sediments indicate a reverse polarity, which is correlated to

    2003-01-01

    Latin American social medicine (LASM) emerged as a movement in the 1970s and played an important role in the Brazilian health care reform of the 1980s, both of which focused on decentralization and on health care as a social right. The dominant health care reform model in Latin America has included a market-driven, private subsystem for the insured and a public subsystem for the uninsured and the poor. In contrast, the Mexico City government has launched a comprehensive policy based on social rights and redistribution of resources. A universal pension for senior citizens and free medical services are financed by grants, eliminating routine government corruption and waste. The Mexico City policy reflects the influence of Latin American social medicine. In this article, I outline the basic traits of LASM and those of the prevailing health care reform model in Latin America and describe the Mexico City social and health policy, emphasizing the influence of LASM in values, principles, and concrete programs.

    Factors associated with CES-D depression among Mexican Americans living on and off the U.S.-Mexico border are examined. Data are from two studies of Mexican American adults. The Border Survey conducted face-to-face interviews in urban U.S.-Mexico border counties of California, Arizona, New Mexico, and Texas (N = 1307). The non-border HABLAS survey conducted face-to-face interviews in Houston, Los Angeles, New York, Philadelphia, and Miami (N = 1288). Both surveys used a multistage cluster sample design with response rates of 67 and 76 %, respectively. The multivariate analysis showed that border residence and higher perceived neighborhood collective efficacy were protective for depression among men. Among men, lower education, unemployment, increased weekly drinking, and poor health status were associated with depression. Among women, alcohol-related problems and poorer health status were also associated with depression. Further examinations of how neighborhood perceptions vary by gender and how these perceptions influence the likelihood of depression are warranted.

    Since 1979, suicide and homicide have alternated as the second and third leading causes of death among young American Indians and Alaska Natives (AI/ANs). From 1979 through 1992, suicide rates for AI/ANs in all age groups were approximately 1.5 times the rates for the overall U.S. population. During 1991-1993, suicide rates for AI/ANs aged 15-24 and 25-34 years were 31.7 and 26.6 per 100,000 population, respectively; males aged 15-34 years accounted for 64% of all AI/AN suicides. In the overall U.S. population during 1991-1993, the rates for persons in these same age groups were 13.0 and 14.5, respectively. Since 1980, suicide has been either the second or third leading cause of death for persons aged 15-24 years in the overall U.S. population. Although knowledge about suicide among AI/ANs has increased, information about the efficacy of suicide prevention and intervention programs in general, and specifically in AI/AN communities, is scarce. In January 1990, following concern raised by tribal officials in 1988 about suicide among youth, a Western Athabaskan tribe in rural New Mexico implemented a suicide prevention and intervention program that targeted tribal members aged 15-19 years. This report summarizes the results of the program through 1997 and indicates that rates of suicide and attempted suicide among this target population decreased substantially after the program was implemented.

    This study addressed the association between items from the General Acculturation Index (GAI) and cardiovascular health. Specifically, we assessed whether ethnic pride was associated with health outcomes after controlling for items regarding language, place where the childhood was spent and ethnic interaction. The study was a cross sectional analysis of demographic and clinical data from a border population of Mexican American adults (n=316) at risk for cardiovascular disease (CVD). Outcomes included smoking and diabetes status, Framingham risk, and metabolic syndrome. Ethnic pride was associated with lower diabetes prevalence, lower Framingham risk, and fewer risk factors for metabolic syndrome, but was not associated with smoking status. Ethnic pride was not associated with the other acculturation items of the GAI. Among an at-risk border population, ethnic pride functioned independently of other acculturation indicators. Ethnic pride may act as a protective factor for diabetes, metabolic syndrome and CVD risk status.

    The southwestern coast of Mexico is marked by active subduction of the Rivera and Cocos plates, producing megathrust earthquakes that tend to recur every 50-100 yr. Herein, we use seismic and GPS data from this region to investigate the potential relationship between earthquakes, tectonic (non-volcanic) tremor, and transient slip along the westernmost 200 km of the Mexico subduction zone. Visual examination of seismograms and spectrograms throughout the 18-month-long MARS seismic experiment reveals clear evidence for frequent small episodes of tremor along the Rivera and Cocos subduction zones beneath the states of Jalisco, Colima, and Michoacán. Using a semi-automated process that identifies prominent energy bursts in envelope waveforms of this new data, analyst-refined relative arrival times are inverted for source locations using a 1-D velocity model. The resulting northwest-southeast trending linear band of tremor is located downdip from the rupture zones of the 1995 Mw 8.0 Colima-Jalisco and 2003 Mw 7.2 Tecoman subduction-thrust earthquakes and just below the regions of afterslip triggered by these earthquakes. Despite the close proximity between tremor and megathrust events, there is no evidence that the time since the last great earthquake influences the spatial or temporal pattern of tremor. A well-defined gap in the tremor beneath the western Colima Graben appears to mark a separation along the subducted Rivera-Cocos plate boundary. From the position time series of 19 continuous GPS sites in western Mexico, we present the first evidence that slow slip events occur on the Rivera plate subduction interface. Unlike the widely-recorded, large-amplitude, slow slip events on the nearly horizontal Cocos plate subduction interface below southern Mexico, slow slip events below western Mexico have small amplitudes and are recorded at relatively few, mostly coastal stations. The smaller slow slip beneath western Mexico may be due to the steeper dip, causing a

    Hepatitis A virus (HAV) remains a public health concern worldwide contributing to significant morbidity in developed and developing countries. This cross-sectional database study estimated the overall HAV seroprevalence and the seroprevalence by gender, age, region and socioeconomic status in Mexico. Between January and October 2010, serum samples collected during the National Health and Nutrition survey (ENSANUT 2006) were obtained from subjects aged 1-95 y. Subjects' gender, age, geographical region and socioeconomic status were extracted from the survey and compiled into a subset database by the Mexican National Institute of Public Health. Anti-HAV antibodies were measured using a chemiluminescent immunoassay. A total of 3658 subjects were included in the according-to-protocol cohort. Overall, the HAV seroprevalence was 84.2%. The HAV seroprevalence rates were similar between females (86.1%) and males (82.2%). The percentage of subjects seropositive for anti-HAV antibodies was highest in adults aged ≥ 20 y (96.9%), followed by adolescents aged 10-19 y (80.1%) and lowest in children aged 1-9 y (45.0%) (p < 0.0001). Regionally, the highest HAV seroprevalence rate was observed in the South (88.8%) followed by Central and Northern Mexico and Mexico City (p = 0.02). The HAV seroprevalence was similar between subjects of high socioeconomic (90.1%) status and of low socioeconomic status (86.6%). This study confirms the intermediate HAV endemicity in Mexico. Cost-effectiveness studies are necessary to evaluate the inclusion of an effective hepatitis A vaccine from a population-based perspective in addition to continuous efforts to improve hygiene and sanitation that have a substantial impact on the disease burden.

    A dengue (DEN) outbreak occurred in the Yucatan State of Mexico in 2002. Three isolates were obtained from patients presenting with DEN-like symptoms, and examined by partial nucleotide sequencing and phylogenetic analysis. The isolates were identified as DEN-2 viruses of the American-Asian genotype; this is the first report of this genotype in the Yucatan State. The DEN-2 viruses of the American-Asian genotype have been associated with more severe disease outcomes. Thus, its introduction into the Yucatan State presents a serious problem to public health authorities. During this outbreak, DEN virus infection was confirmed in 18% (282 of 1,560) of the patients who presented with DEN-like symptoms. Of these, 87 (31%) patients met the World Health Organization criteria for dengue hemorrhagic fever, including two patients who died. The majority (77%) of the patients experienced secondary infections in this epidemic.

    The Cenozoic fill of the Gulf of Mexico basin contains a continuous record of sediment supply from the North American continental interior for the past 65 million years. Regional mapping of unit thickness and paleogeography for 18 depositional episodes defines patterns of shifting entry points of continental fluvial systems and quantifies the total volume of sediment supplied during each episode. Eight fluvio-deltaic depocenters, named for geographic similarities to entry points and drainage basins of modern rivers, are present. From southwest to northeast, they are the Rio Bravo, Rio Grande, Guadalupe, Colorado, Houston-Brazos, Red, Mississippi, and Tennessee axes. Sediment volume was calculated from hand-contoured unit thickness maps compiled from basin-wide well and seismic control. Using a GIS algorithm to sum volumes within polygons bounding interpreted North American river contribution, the total extant volume was then calculated. General compaction factors were used to convert modern volume to quantitative approximations of total grain volume. Grain volume rate of supply for each depositional episode was then calculated. Values vary by more than an order of magnitude. Supply rate has commonly varied by two-fold or more between successive depositional episodes. Sediment supply is a significant, independent variable in development of stratigraphic sequences within the Gulf basin. Paleogeographic maps of the continental interior for eleven Cenozoic time intervals display the evolving and complex interplay of intracontinental tectonism, climate change, and drainage basin evolution. Five tectono-climatic eras are differentiated: Paleocene late Laramide era; early to middle Eocene terminal Laramide era; middle Cenozoic (Late Eocene—Early Miocene) dry, volcanogenic era; middle Neogene (Middle—Late Miocene) arid, extensional era; and late Neogene (Plio—Pleistocene) monsoonal, epeirogenic uplift era. Sediment supply to the GOM reflects the interplay of (1

    Our current understanding of mid-Cretaceous global change is largely based on investigations of pelagic sections from southern Europe and deep sea drilling sites. Much less information exists from other continents and from hemipelagic sections deposited on continental margins. This investigation seeks to broaden our understanding of mid-Cretaceous global change by focusing on the record from hemipelagic sections deposited along the continental margin of northeastern Mexico. The major goals are to compare the record, timing, and extent of the Oceanic Anoxic Events (OAEs) in Mexico and other areas, and to determine the relationship between these events and the global burial of organic material using carbon isotopes. We have investigated four sections from the Sierra Madre Oriental, integrating biostratigraphy, magnetostratigraphy and carbon isotope stratigraphy. Carbon isotopes, measured on the organic carbon (Corg) fraction, show identical stratigraphic changes to curves from Barremian to lower Albian European and Pacific deep-sea sections. Our results add new detail to the C-isotope stratigraphy of the middle and late Albian interval. Three abrupt peaks in Corg content correlate with OAE1a (early Aptian), OAE1b (early Albian) and an event in the late Aptian Globigerinelloides algerianus Zone. All three events are marked by short-term, 0.5-3 per mil decreases in C-isotope values followed by increases of similar magnitude. The decreases may reflect changes in the type of Corg, the nature of carbon cycling, or an increase in hydrothermal activity. The increases in C-isotope values reflect widespread burial of Corg. The similar shape of the C-isotope curves in Mexico and other areas, and the response of C-isotopes to the OAEs, indicate that the late Aptian episode was extensive, and that OAE1a and OAE1b were global. The three anoxic events appear to correlate with rising relative sea level. OAE1a also corresponds to major changes in nannofossil assemblages; the well

    Laguna de Terminos is a 2,500 km{sup 2} coastal lagoon in the southern Gulf of Mexico, located between 18{degrees} 20` and 19{degrees} 00` N, and 91{degrees} 00` and 92{degrees} 20` W (Figure 1). It is a shallow lagoon, with a mean depth of 3.5 m and connected to the Gulf of Mexico through two permanent inlets, Puerto Real to the east and Carmen to the west. Several rivers, most of them from the Grijalva-Usumacinta basin (the largest in Mexico and second largest in the Gulf of Mexico), drain into the lagoon with a mean annual discharge of 6 X 10{sup 9} m{sup 3}/year. This lagoon has been studied systematically, and is probably one of the best known in Mexico. An excellent overview of this lagoon can be found in Yanez-Arancibia and Day. The continental shelf north of Terminos, the Campeche Bank, is the main oil-producing zone in Mexico with a production of about 2 X 10{sup 6} barrels/day. It is also the main shrimp producer in the southern Gulf, with a mean annual catch of 18,000 tonnes/year, which represents 38 to 50% of the national catch in the Gulf of Mexico. The economic importance of this region, along with its extremely high biodiversity, both in terms of species and habitats, has prompted the Mexican government to study the creation of a wildlife refuge around Terminos. Thus, it is very important to know the current levels of pollutants in this area, as a contribution to the management plan of the proposed protected area.

    Background This paper examines the association between perceived neighborhood violence, perceived neighborhood collective efficacy, and binge drinking among Mexican Americans residing on the U.S.-Mexico border. Methods Data were collected from a multi-stage cluster sample of adult Mexican Americans residing in the U.S.-Mexico border areas of California, Arizona, New Mexico, and Texas (N=1,307). The survey weighted response rate was 67%. Face-to-face interviews lasting approximately one hour were conducted in respondents’ homes in English or Spanish. Path analysis was used to test whether collective efficacy mediated the impact of perceived neighborhood violence on binge drinking. Results Among 30+ year old women, perceived neighborhood collective efficacy mediated the effects of perceived neighborhood violence on binge drinking in a theoretically predicted way: Lower perceptions of violence predicted an increased perception of collective efficacy, which in turn, predicted less binge drinking. Direct effects of violence perceptions on binge were non-significant. Younger 18 to 29 year old women showed a similar (but non-significant) pattern of effects. Perceived collective efficacy also mediated the effects of perceived violence on binge drinking among men, but in opposite ways for older and younger men. Older men showed the same mediating effect as older women, but the effect reversed among younger men due to a strong, positive relation between collective efficacy and binge drinking. There were also age differences in the direct effect of violence perceptions on binge drinking: Perceptions of violence predicted more binge drinking among young men, but less among older men. Conclusions These results highlight the complexity of people’s responses to neighborhood characteristics in regard to their drinking. Young men in particular seem to react very differently to perceptions of collective efficacy than other groups. However, among both men and women, collective

    Obesity is a critical problem among Mexican youth, but few studies have investigated associations among physical activity (PA) modes and anthropometrics in this population. This study examined associations among active commuting to school (ACS), sports or other organized PA, outdoor play, and body mass index (BMI) percentile and waist circumference (WC) among Mexican youth. Parents of school children (N = 1996, ages 6 to 14 years, 53.1% female) in 3 Mexican cities reported PA participation using the (modified) fourth grade School Physical Activity and Nutrition Survey. Trained assessors measured BMI percentile and WC in person. Parents reported that 52.3% of children engaged in ACS, 57.3% participated in sports or organized PA, and a median of 2 days in the previous week with at least 30 minutes of outdoor play. In complete case analyses (n = 857), ACS was negatively associated with BMI percentile, and outdoor play was negatively associated with WC after adjusting for school, age, sex, and income. In analyses incorporating data from multiple imputation (N = 1996), outdoor play was negatively associated with WC (all Ps < . 05). ACS and outdoor play are favorably associated with anthropometrics and may help prevent childhood obesity in Mexico. ACS and outdoor play should be priorities for increasing youth PA in Mexico.

    Understanding influences on health-related quality of life (HRQL) is critical in order to track and improve the health of poor, vulnerable populations and reduce health disparities. However, studies assessing HRQL of minorities are relatively scarce. The purpose of this study was to document personal and socioenvironmental correlates to HRQL. The study population is Mexican Americans in the Texas-Mexico border region living in colonias - unincorporated, impoverished settlements with substandard living conditions along the U.S.-Mexico border. Mexican Americans living in colonias are one of the most disadvantaged, hard-to-reach minority groups in the United States. We used data from the Integrated Health Outreach System Project collected in 2002 and 2003. Our sample included 386 participants randomly selected and interviewed face-to-face with a structured survey. We measured HRQL and examined personal and socioenvironmental correlates. Unadjusted and adjusted (multivariate) logistic regression models were used for data analyses. We found that border Mexican Americans living in colonias were of similar mental health status compared to the general population of the United States, but worse off in terms of physical health. Poor education and long-term residency in colonias were predictors of lower physical health. Women reported worse mental health than men. Length of time living in a colonia, co-morbidity status, and perceived problems with access to healthcare was associated with poorer mental health status. This study provides information for health professionals and policymakers and underscores the need to provide better preventive and medical services for underserved populations. Major findings indicate the need for additional research centered on further exploration of the impact of economic, cultural, and social influences on HRQL among severely disadvantaged populations.

    Urban centers in Latin American often face high levels of air pollution as a result of economic and industrial growth. Decisions with regard to industry, transportation, and development will affect air pollution and health both in the short term and in the far future through climate change. We investigated the pollution health consequences of modest changes in fossil fuel use for three case study cities in Latin American: Mexico City, Mexico; Santiago, Chile; and São Paulo, Brazil. Annual levels of ozone and particulate matter were estimated from 2000 to 2020 for two emissions scenarios: (1) business-as-usual based on current emissions patterns and regulatory trends and (2) a control policy aimed at lowering air pollution emissions. The resulting air pollution levels were linked to health endpoints through concentration-response functions derived from epidemiological studies, using local studies where available. Results indicate that the air pollution control policy would have vast health benefits for each of the three cities, averting numerous adverse health outcomes including over 156,000 deaths, 4 million asthma attacks, 300,000 children's medical visits, and almost 48,000 cases of chronic bronchitis in the three cities over the 20-year period. The economic value of the avoided health impacts is roughly 21 to 165 billion Dollars (US). Sensitivity analysis shows that the control policy yields significant health and economic benefits even with relaxed assumptions with regard to population growth, pollutant concentrations for the control policy, concentration-response functions, and economic value of health outcomes. This research demonstrates the health and economic burden from air pollution in Latin American urban centers and the magnitude of health benefits from control policies.

  9. Isotopic cycling in a tropical treeline environment: North American monsoon dynamics at Nevado de Colima, Mexico

    NASA Astrophysics Data System (ADS)

    Hartsough, Peter Christopher

    High elevation sites are especially sensitive to environmental change. One way to get a longer perspective on global change in mountain regions is paleoenvironmental records from tree rings. Data on the response of high elevation species to climatic events is sparse and records used for reconstruction often necessarily come from lower elevation, higher latitude stations. We have set up a unique field site where we are co-monitoring tree growth and weather in real time. In May 2001 we established a monitoring site at 3770m (12,370ft) on Nevado de Colima (19° 34.8'N, 103° 37.3'W) at the western end of the trans-volcanic belt in Southwestern Mexico. The monitoring site consists of an automated weather station and two dendrometer networks for the simultaneous measurement of climate and tree growth parameters. Although we have experienced several equipment setbacks due to the challenging environment, important results relating to growth dynamics and response to climate have surfaced. This field site, near the edge of the tropics, is an important monitoring location for both intra and extra tropical circulation systems. Historical records in the area are of short duration (less than 60 years) so determining the nature of decadal or longer scale fluctuations requires the use of proxy records. Mexican Mountain Pines (Pinus hartwegii Lindl.) growing on Nevado de Colima are under the influence of several large-scale climate features---most notably the North American Monsoon and ENSO. Dendrochronology studies in the region have shown a sensitivity of tree growth to warm season precipitation. The North American Monsoon is still a poorly understood system and an historical perspective is needed for increased confidence in predictive models and forecasting. Careful measurement of tree growth over the five years of the project has led to a clearly defined dormant period over the relatively arid winter. Dendrometer data have shown onset of growth to be closely tied to soil

    Hematological and serum biochemistry analyses were determined on 51 Central American river turtles (Dermatemys mawii) during the dry and rainy seasons of 2006. Turtles came from two sites: Pantanos de Centla Biosphere Reserve and a turtle breeding farm, both located in Tabasco State, Mexico. Physical examination and body measures of animals were performed. Incidence and prevalence of hemoparasites were explored. Captive organisms were in poor physical condition while wild turtles were apparently healthy. There were differences in several hematological parameters related with the condition and the season. During the dry season captive turtles exhibited higher levels of uric acid and urea, as well as lower levels of glucose. Haemogregarina sp. was detected in 100% of the wild individuals, but not in captive individuals. Its incidence was greater during the rainy season. This is the first health assessment and hematology study of this critically endangered species.

    Summer monsoonal rains (the southwest monsoon) are an important source of moisture for parts of the southwestern United States and northern Mexico. Improved documentation of the variability in the southwest monsoon is needed because changes in the amount and seasonal distribution of precipitation in this semiarid region of North America influence overall water supply and fire severity. Comparison of abundance variations in the planktic foraminifer Globigerinoides sacculifer in marine cores from the western and northern Gulf of Mexico with terrestrial proxy records of precipitation (tree-ring width and packrat-midden occurrences) from the southwestern United States indicate that G. sacculifer abundance is a proxy for the southwest monsoon on millennial and submillennial time scales. The marine record confirms the presence of a severe multicentury drought centered ca. 1600 calendar (cal.) yr B.P. as well as several multidecadal droughts that have been identified in a long tree-ring record spanning the past 2000 cal. yr from westcentral New Mexico. The marine record further suggests that monsoon circulation, and thus summer rainfall, was enhanced in the middle Holocene (ca. 6500-4500 14C yr B.P.; ca. 6980-4710 cal. yr B.P.). The marine proxy provides the potential for constructing a highly resolved, well-dated, and continuous history of the southwest monsoon for the entire Holocene. ?? 2005 Geological Society of America.

    Objectives We sought to determine the prevalence of anti-Toxoplasma gondii antibodies in Yoremes and to identify associations of T. gondii exposure with sociodemographic, clinical and behavioural characteristics of Yoremes. Design A cross-sectional survey. Setting Yoremes were enrolled in the locality of Tierra Blanca in the municipality of Navojoa in Sonora State, Mexico. Participants We studied 200 Yoremes (Mayos); they are an indigenous ethnic group living in a coastal region in northwestern Mexico. Primary and secondary outcome measures We assessed the prevalence of anti-Toxoplasma IgG and IgM antibodies in participants using enzyme-linked immunoassays. We used a standardised questionnaire to obtain the characteristics of Yoremes. The association of T. gondii exposure and Yoremes’ characteristics was assessed by bivariate and multivariate analyses. Results Of the 200 Yoremes studied (mean age: 31.50±18.43 years), 26 (13.0%) were positive for anti-T. gondii IgG antibodies and 19 (73.1%) of them were also positive for anti-T. gondii IgM antibodies. Seroprevalence of T. gondii infection did not vary with sex, educational level, occupation or socioeconomic status. In contrast, multivariate analysis of sociodemographic and behavioural characteristics showed that T. gondii exposure was associated with increasing age (OR=1.02; 95% CI 1.00 to 1.04; p=0.03) and consumption of squirrel meat (OR=4.99; 95% CI 1.07 to 23.31; p=0.04). Furthermore, seroprevalence of T. gondii infection was significantly higher in Yoremes with a history of lymphadenopathy (p=0.03) and those suffering from frequent abdominal pain (p=0.03). In women, T. gondii exposure was associated with a history of caesarean sections (p=0.03) and miscarriages (p=0.02). Conclusions We demonstrate, for the first time, serological evidence of T. gondii exposure among Yoremes in Mexico. Results suggest that infection with T. gondii might be affecting the health of Yoremes. Results may be useful for an

    Background Intimate partner violence (IPV) against women is a global public health problem, yet data on IPV against Native American women are extremely limited. We conducted a cross-sectional study of Native American women to determine prevalence of lifetime and past-year IPV and partner injury; examine IPV in relation to pregnancy; and assess demographic and socioeconomic correlates of past-year IPV. Methods Participants were recruited from a tribally-operated clinic serving low-income pregnant and childbearing women in southwest Oklahoma. A self-administered survey was completed by 312 Native American women (96% response rate) attending the clinic from June through August 1997. Lifetime and past-year IPV were measured using modified 18-item Conflict Tactics Scales. A socioeconomic index was created based on partner's education, public assistance receipt, and poverty level. Results More than half (58.7%) of participants reported lifetime physical and/or sexual IPV; 39.1% experienced severe physical IPV; 12.2% reported partner-forced sexual activity; and 40.1% reported lifetime partner-perpetrated injuries. A total of 273 women had a spouse or boyfriend during the previous 12 months (although all participants were Native American, 59.0% of partners were non-Native). Among these women, past-year prevalence was 30.1% for physical and/or sexual IPV; 15.8% for severe physical IPV; 3.3% for forced partner-perpetrated sexual activity; and 16.4% for intimate partner injury. Reported IPV prevalence during pregnancy was 9.3%. Pregnancy was not associated with past-year IPV (odds ratio = 0.9). Past-year IPV prevalence was 42.8% among women scoring low on the socioeconomic index, compared with 10.1% among the reference group. After adjusting for age, relationship status, and household size, low socioeconomic index remained strongly associated with past-year IPV (odds ratio = 5.0; 95% confidence interval: 2.4, 10.7). Conclusions Native American women in our sample experienced

    1991-08-01

    Sequence stratigraphic analysis using seismic baselap terminations is not usually applicable to the Miocene section of offshore western Louisiana, Gulf of Mexico, because of the lack of identifiable baselap and expansion at growth faults. Identification of condensed sections, which usually occur at the top of the transgressive systems tracts and are easily identifiable marker beds in nannofossil, well log, and seismic data, is an alternative approach to sequence stratigraphic analysis. Integrated interpretation of high-resolution calcareous nannofossil abundance data from nine wells, 91 paleontological reports (foraminifera), well log data from 73 wells, and more than 2,400 mi of seismic data defines seven genetic stratigraphic sequences and corresponding systems tracts from the late Early Miocene through the early Pliocene. The highstand systems tracts are dominant on the shelf and slop in the study area. The transgressive systems tracts are rather thin. The lowstand systems tracts are usually limited on the downthrown sides of major growth faults except for a thick lowstand prograding wedge of the Ampbistegina B-Discorbis B sequence deposited on the shelf and slope. The seismic amplitudes of highstand systems tracts are moderate to variable in the updip area and low in the downdip area. The seismic attributes of transgressive systems tracts are moderate amplitude, high frequency, and moderate to high community. The condensed section exhibits a strong reflection. Seismic attributes of lowstand systems tracts are low amplitude and low continuity, and sometimes a hummocky pattern.

  18. Millennial-scale records of North American Monsoon in time and space during the last glacial period: reconstructions from arid northern Mexico

    The arid northern Mexico is part of the Sonora and Chihuahua Deserts and both the deserts belong to the North American Desert system. The North American Monsoon (NAM) or Mexican Monsoon refers to the system that brings summer precipitation to arid northern Mexico and southwestern USA. It contributes ca. 70-80% of total annual precipitation along the western slopes of the Sierra Madre Occidental (northern Mexico) and ca. 40-50% of total precipitation in Arizona and New Mexico (southwest USA). High-resolution geochemical data from lacustrine deposits located between 23°N and 31°N (paleolakes La Salada, Babicora and San Felipe) provide spatio-temporal and millennial-scale paleohydrological records related to the dynamics of summer precipitation as well as westerly winter storms over the last glacial period. The inverse relationship between proxy records of runoff into lacustrine basins of northern Mexico and winter precipitation over the southwestern USA indicate that the westerly winter storms had minimal influence south of 30°N and the paleohydrological changes are mainly summer precipitation controlled. The variation in summer season precipitation between 20 and 60 cal. kyr BP was driven by long term changes in summer insolation. During an interval of lower summer insolation (i.e. >60 cal. kyr BP), the higher summer precipitation could be related to the NAM expansion as a result of reduced north hemisphere ice sheets. On a millennial-scale, the region received more than average precipitation during the warm interstadials and vice versa.

    The purpose of this study was to model the cost of delivering behavioural health services to rural Native American populations using telecommunications and compare these costs with the travel costs associated with providing equivalent care. Behavioural telehealth costs were modelled using equipment, transmission, administrative and IT costs from an established telecommunications centre. Two types of travel models were estimated: a patient travel model and a physician travel model. These costs were modelled using the New Mexico resource geographic information system program (RGIS) and ArcGIS software and unit costs (e.g. fuel prices, vehicle depreciation, lodging, physician wages, and patient wages) that were obtained from the literature and US government agencies. The average per-patient cost of providing behavioural healthcare via telehealth was US$138.34, and the average per-patient travel cost was US$169.76 for physicians and US$333.52 for patients. Sensitivity analysis found these results to be rather robust to changes in imputed parameters and preliminary evidence of economies of scale was found. Besides the obvious benefits of increased access to healthcare and reduced health disparities, providing behavioural telehealth for rural Native American populations was estimated to be less costly than modelled equivalent care provided by travelling. Additionally, as administrative and coordination costs are a major component of telehealth costs, as programmes grow to serve more patients, the relative costs of these initial infrastructure as well as overall per-patient costs should decrease. © The Author(s) 2015.

    The exploitation of minerals has played a significant role in population growth and development of the U.S.Mexico border region. Recent proposed changes in regulations related to mining in the United States and changes in mining and investment regulations in Mexico have led to increased mineral exploration and development in Mexico, especially in the border region. As a preliminary step in the study of the mineral industry of this area, the Center for Inter-American Mineral Resource Investigations (CIMRI) of the U.S. Geological Survey has compiled mine and occurrence data for nonfuel minerals in the border region. Analysis of this information indicates that a wide variety of metallic and industrial mineral commodities are present which can be used in agriculture, infrastructure, environmental improvement, and other industries. Therefore, mining will continue to play a significant role in the economy of this region.

    Multidisciplinary field projects can be very useful to a more fundamental understanding of the world around us, though these projects are not as common as they should be. In particular, the combination of archeology and geology combines our understanding of human behavior and human use of the landscape with an intimate knowledge of geologic processes and the materials available for human use in order to gain a broader understanding of human-Earth interaction. Here we present data from a cross-disciplinary project that uses a common dataset, archeological artifacts, to explore the anthropological and geologic implications of useage patterns. Archeological excavations and surveys conducted by the Office of Contract Archeology in 2007 along the route of the proposed international border fence reveal patterns of use of geologic materials by Archaic, Formative and Protohistoric Native Americans in the Boot Heel of southwestern New Mexico. Thousands of artifacts were recorded in multiple sites from Guadalupe Pass in the southern Peloncillo Mountains to the Carrizalillo Hills west of Columbus. We identified the lithologies of artifacts, ranging from projectile points to groundstones, and then constructed material movement maps based on either known procurement sites ("quarries") or outcrops identified as the closest source to a given site for each lithology. Not unexpectedly, the majority of the rock types utilized by native peoples are local siliceous volcanic materials. However, several artifacts constructed from obsidian were transported into the region from northern Mexico and eastern Arizona, indicating long-distance travel and/or trade routes. We also examine useage pattern difference between Archaic, Formative and Protohistoric sites. Additionally, a dramatic change in distribution of sources for geologic materials occurs between one pre-Spanish site and one post-Spanish site that are adjacent to one another.

    Rationale: Gene promoter methylation detected in sputum predicts lung cancer risk in smokers. Compared with non-Hispanic whites (NHW), Hispanics have a lower age-standardized incidence for lung cancer. Objectives: This study compared the methylation prevalence in sputum of NHWs with Hispanics using the Lovelace Smokers cohort (n = 1998) and evaluated the effect of Native American ancestry (NAA) and diet on biomarkers for lung cancer risk. Methods: Genetic ancestry was estimated using 48 ancestry markers. Diet was assessed by the Harvard University Dietary Assessment questionnaire. Methylation of 12 genes was measured in sputum using methylation-specific polymerase chain reaction. The association between NAA and risk for methylation was assessed using generalized estimating equations. The ethnic difference in the association between pack-years and risk for lung cancer was assessed in the New Mexico lung cancer study. Measurements and Main Results: Overall Hispanics had a significantly increased risk for methylation across the 12 genes analyzed (odds ratio, 1.18; P = 0.007). However, the risk was reduced by 32% (P = 0.032) in Hispanics with high versus low NAA. In the New Mexico lung cancer study, Hispanic non–small cell lung cancer cases have significantly lower pack-years than NHW counterparts (P = 0.007). Furthermore, compared with NHW smokers, Hispanic smokers had a more rapidly increasing risk for lung cancer as a function of pack-years (P = 0.058). Conclusions: NAA may be an important risk modifier for methylation in Hispanic smokers. Smoking intensity may have a greater impact on risk for lung cancer in Hispanics compared with NHWs.

We also took samples directly from a male tapir captured at the Montes Azules Biosphere Reserve. Both reserves are in Chiapas, Mexico. We used five techniques: flotation, MacMaster, micrometric, Ritchie's sedimentation and Ferreira's quantitative. In addition, we collected ectoparasites from animals captured in both reserves and from a captive couple from Tuxtla Gutierrez, Chiapas. These nematodes and protozoans were found: Agriostomun sp., Lacandoria sp., Neomurshidia sp., Trichostrongylus sp., Strongylus sp., Brachylumus sp, and an unidentified species of ancilostomaide. We also found Eimeria sp. and Balantidium coli, as well as the mites Dermacentor halli, Dermacentor latus, Amblyomma cajannense, Amblyomma coelebs, Amblyomma ovale, Anocentor nitens and Ixodes bicornis.

    Background Exposure to arsenic (As) concentrations in drinking water > 150 μg/L has been associated with risk of diabetes and cardiovascular disease, but little is known about the effects of lower exposures. Objective This study aimed to examine whether moderate As exposure, or indicators of individual As metabolism at these levels of exposure, are associated with cardiometabolic risk. Methods We analyzed cross-sectional associations between arsenic exposure and multiple markers of cardiometabolic risk using drinking-water As measurements and urinary As species data obtained from 1,160 adults in Chihuahua, Mexico, who were recruited in 2008–2013. Fasting blood glucose and lipid levels, the results of an oral glucose tolerance test, and blood pressure were used to characterize cardiometabolic risk. Multivariable logistic, multinomial, and linear regression were used to assess associations between cardiometabolic outcomes and water As or the sum of inorganic and methylated As species in urine. Results After multivariable adjustment, concentrations in the second quartile of water As (25.5 to < 47.9 μg/L) and concentrations of total speciated urinary As (< 55.8 μg/L) below the median were significantly associated with elevated triglycerides, high total cholesterol, and diabetes. However, moderate water and urinary As levels were also positively associated with HDL cholesterol. Associations between arsenic exposure and both dysglycemia and triglyceridemia were higher among individuals with higher proportions of dimethylarsenic in urine. Conclusions Moderate exposure to As may increase cardiometabolic risk, particularly in individuals with high proportions of urinary dimethylarsenic. In this cohort, As exposure was associated with several markers of increased cardiometabolic risk (diabetes, triglyceridemia, and cholesterolemia), but exposure was also associated with higher rather than lower HDL cholesterol.

    To better understand the occurrence and population structure of horseshoe crabs in the northern Gulf of Mexico, we sampled animals on Petit Bois Island, Dauphin Island, and Fort Morgan. To determine if major life history events such as spawning, molting, or mortality occurred more frequently at certain locations and times, we counted molts, live animals (noted whether animals were alone or amplexed for spawning), and carcasses. We also tested the hypothesis that demographics of molts or carcasses found on local beaches represent nearby live animal populations by tracking the redistribution of tagged molts placed at variable distances from shore (2, 50, 100 m). Overall, our data suggested a greater occurrence of spawning adults and actively molting juveniles on Petit Bois Island compared to other sites. The number of specimens found at Dauphin Island and Fort Morgan declined since 2012, possibly due to a regional-scale change in environmental conditions. Size frequency distributions of molts and carcasses collected during 2015 were similar to values from previous studies, but showed a higher number of subadult horseshoe crab carcasses in 2015 compared to other years. Tagged molts were recovered at a rate of 2.5%, suggesting that few molts deposited in nearby waters make it to local beaches. Tagged molts were recovered at 1 - 22 days following field placement, with the majority of recovered molts found after 1 day. Because smaller crabs (<40 mm size) stay close to natal beaches when molting, their molts are most likely to wash ashore. Data provided by this study will help inform future research on horseshoe crab ecology and assess how natural and anthropogenic perturbaRons may affect horseshoe crab populaRons in the northern Gulf of Mexico.

  19. Summary of Flow Loss between Selected Cross Sections on the Rio Grande in and near Albuquerque, New Mexico

    The upper middle Rio Grande Basin, as defined by the U.S. Army Corps of Engineers, extends from the headwaters of the Rio Grande in southwestern Colorado to Fort Quitman, Texas. Most of the basin has a semiarid climate typical of the southwestern United States. This climate drives a highly variable streamflow regime that contributes to the complexity of water management in the basin. Currently, rapid population growth in the basin has resulted in increasing demands on the hydrologic system. Water management decisions have become increasingly complex because of the broad range of interests and issues. For these reasons, the U.S. Geological Survey, in cooperation with the City of Albuquerque, New Mexico, conducted paired flow measurements at two cross sections to determine cross-sectional loss in the Albuquerque reach of the Rio Grande. This report statistically summarizes flow losses in the Albuquerque reach of the Rio Grande during the winter nonirrigation season from December 1996 to February 2000. The two previous flow-loss investigations are statistically summarized. Daily mean flow losses are calculated for the winter nonirrigation season using daily mean flows at three selected Rio Grande streamflow-gaging stations.For the winter nonirrigation season cross-sectional measurements (1996-2000), an average of 210 cubic feet per second was returned to the river between the measurement sites, of which 165 cubic feet per second was intercepted by riverside drains along the 21.9-mile reach from the Rio Grande near Bernalillo to the Rio Grande at Rio Bravo Bridge streamflow-gaging stations. Total cross-sectional losses in this reach averaged about 90 cubic feet per second. Regression equations were determined for estimating downstream total outflow from upstream total inflow for all three paired measurement studies. Regression equations relating the three daily mean flow recording stations also were determined. In each succeeding study, additional outside variables

    2009-12-01

    We present initial results of a petrological, magnetic and geochemical study of El Mimbral and La Lajilla sections that span the Cretaceous-Paleogene (K-Pg) boundary. K-Pg sections in northeastern Mexico have been intensively studied in past years, mainly because of their relationship to the Chicxulub crater in the Yucatan platform and for investigating the nature, origin, stratigraphic relations and age of the impact ejecta deposits. The K-Pg boundary is preserved in between hemipelagic marls and limestones of the Mendez (Maastrichtian) and Velasco (Paleocene) formations. The two sections are situated about 1000 km away from Chicxulub and K-Pg deposits are part of the proximal ejecta and the complex channelized siliciclastic units. We had separated the siliciclastic units into two parts, with a basal coarse poorly graded spherulitic bed some 0.2 to 1 m thick and a second part with several sandstone siltstone beds that have been grouped in various ways in previous studies. In the field, samples were collected across stratigraphic profiles for rock magnetic, petrological and geochemical analyses. Using field observations and analytical data, detailed columns for the two localities are prepared. Rock magnetic measurements include susceptibility, remanent and isothermal magnetization and remanent coercivity. Magnetic hysteresis loops and IRM and back-field demagnetization were measured for samples of spherulitic bed. X-ray fluorescence analyses on whole rock were complemented with previous data obtained for the Mimbral section by atomic absorption spectrometry and inductively coupled plasma mass spectrometry (including platinum group elements). Further detailed analysis concentrated in the ejecta material. The spherulitic bed is characterized by Fe-Mg rich chlorite and Si-Al-K rich glass spherules and carbonate accretionary lapilli spherules. The silicic component spherules are altered to calcite or chlorite-smectite, with some retaining glass cores. Spherules have

    To further evaluate the academic representation of female urology residents in the United States, we reviewed abstracts from the Mid-Atlantic American Urological Association (MA-AUA) sectional meetings to determine if the recent increase in the number of female urology residents mirrored an increase in this group's abstract authorship. Full text abstracts from the MA-AUA meetings were analyzed from 2008-2014 excluding one joint section meeting. First-author gender was determined by querying publicly available institutional websites, social media platforms, and the U.S. News & World Report. First-author gender was indeterminable in 10 abstracts based on search criteria and these were excluded. Individual abstracts were broadly categorized based on keywords into one of several topics. Chi-squared statistical tests examined the relationship between first-authorship gender, publication year, and abstract category. The number of female urology residents in the MAAUA increased over the study period. A total of 484 abstracts were analyzed. Three hundred ninety-three abstracts (81%) included a male first-author, whereas 81 abstracts (17%) included a female first-author. Female first authorship ranged between 13% and 25% annually. Comparison of male-to-female first authorship was statistically significant at all years evaluated (P<0.001). There was a statistically significant difference between male and female first authorship in all topic categories (P<0.01) except Education/Other (P=0.56). Despite continued gains and increasing female representation within urology, these data highlight significantly fewer female first-authors at the regional Mid-Atlantic section meetings. Larger studies are necessary to identify contributing factors and further areas for improvement toward decreasing gender imbalances within the academic community. Copyright © 2017 Elsevier Inc.

    The section 23 mine is one of about 18 large uranium mines opened in sandstones of the fluvial Westwater Canyon Member of the Jurassic Morrison Formation in the Ambrosia Lake mining district during the early 1960s. The Ambrosia Lake district is one of several mining districts within the Grants mineral belt, an elongate zone containing many uranium deposits along the southern flank of the San Juan basin. Two distinct types of ore occur in the mine. Primary ore occurs as peneconcordant layers of uranium-rich authigenic organic matter that impregnates parts of the reduced sandstone host rocks and which are typically elongate in an east-southeast direction subparallel both to the sedimentary trends and to the present-day regional strike of the strata. These are called prefault or trend ores because of their early genesis and their elongation and alinement. A second type of ore in the mine is referred to as postfault, stacked, or redistributed ore. Its genesis was similar to that of the roll-type deposits in Tertiary rocks of Wyoming and Texas. Oxidation, related to the development of a large tongue of oxidized rock extending from Gallup to Ambrosia Lake, destroyed much of the primary ore and redistributed it as massive accumulations of lower grade ores bordering the redox interface at the edge of the tongue. Host rocks in the southern half of sec. 23 (T. 14 N., R. 10 W.) are oxidized and contain only remnants of the original, tabular, organic-rich ore. Thick bodies of roll-type ore are distributed along the leading edge of the oxidized zone, and pristine primary ore is found only near the north edge of the section. Organic matter in the primary ore was derived from humic acids that precipitated in the pores of the sandstones and fixed uranium as both coffinite and urano-organic compounds. Vanadium, molybdenum, and selenium are also associated with the ore. The secondary or roll-type ores are essentially free of organic carbon and contain uranium both as coffinite and

    To describe the trends in caesarian sections (CS) associated with non-clinical factors in women who attended a birthing educational facility, also known as 'Centro de Educación,' (CEPAPAR) in Mexico City. Data from 992 births of 847 women that occurred from 1988-2000 were analyzed using linear regression to identify the association between non-clinical factors and time-trends in CS. The overall incidence of CS was 32.8%, with an 8% average annual increase. Until 1994 the percentage of CS remained relatively steady at 30%, increasing to 40% in subsequent years. In analyzing trends in CS and their relationship with non-clinical factors from 1988-2000, the increased incidence of CS during this period was higher among births where no birth attendant was present, for first-time mothers, and in larger hospitals (>50 beds). Results show that the increased incidence of CS is associated with non-clinical factors such as size of the hospital and the presence of a birth attendant. A model of support for women which includes information, counseling, and the presence of a birth attendant during labor can contribute to reducing the risk of unnecessary CS in populations such as that studied.

    This paper examines driving under the influence (DUI) arrests and other related factors among Mexican Americans living in U.S.-Mexico border and non-border areas. Respondents in the non-border areas (primarily Houston and Los Angeles) constitute a multistage probability sample (N=1288) of these areas, interviewed as part of the 2006 Hispanic Americans Baseline Alcohol Survey (HABLAS). Respondents in the border area (N=1307) were interviewed between March 2009 and July 2010 and constitute a household probability sample of Mexican Americans living on the border. In both surveys, data were collected during computer assisted interviews conducted in respondents' homes. The HABLAS and the border sample response rates were 76% and 67%, respectively. Border or non-border residential location was not associated with self-reported DUI, 12 month DUI arrest, or lifetime DUI arrest. An increase in consumption of 5 drinks per week was associated with an 18% increase in the chance of self-reporting DUI and an 18% increase in the probability of a lifetime DUI arrest. Binge drinkers were more likely to self-report a DUI event (OR=2.85, 95% CI=1.61-5.03; p<.001) and a lifetime DUI arrest (OR=2.81; 95% CI=1.43-5.53, p<.01). Most respondents, independent of residential location, recognized DUI as a major problem affecting Hispanics. However, while most correctly identified the legal blood alcohol content to drive in their state as .08 g/dl or lower, approximately one third of individuals were unaware of the legal limit. Compared to their non-border counterparts, border men were more likely to identify a bar/tavern/club and border women were more likely to identify a friend or relative's home as the places of last drink before the most recent DUI trip originated. In conclusion, border and non-border Mexican Americans are not different regarding DUI rates. These rates are high in both groups, especially among men. Intervention strategies to decrease DUI should be implemented not only in

    Objectives HIV testing is critical to the delivery of comprehensive HIV prevention and care services, yet coverage of sexual minorities by HIV testing programmes remains insufficient in many low- and middle-income countries, including Mexico. The objective of this study was to identify the prevalence and correlates of HIV testing among men who have sex with men (MSM) in Tijuana, Mexico. Methods We conducted a cross-sectional study (2012–2013) among 189 MSM recruited via respondent-driven sampling (RDS). RDS-weighted logistic regression was used to identify correlates of prior HIV testing. Results RDS-adjusted prevalence of prior and recent (≤12 months) HIV testing was 63.5% (95% CI 51.9% to 73.5%) and 36.8% (95% CI 25.4% to 46.4%), respectively. Prior HIV testing was positively associated with older age (adjusted OR (AOR)=1.09, 95% CI 1.04 to 1.15), being born in Tijuana (AOR=2.68, 95% CI 1.05 to 6.86), higher levels of education (AOR=2.65, 95% CI 1.08 to 6.53), identifying as homosexual or gay (AOR=3.73, 95% CI 1.48 to 9.42), being more ‘out’ about having sex with men (AOR=1.28, 95% CI:1.02 to 1.62), and a history of sexual abuse (AOR=3.24, 95% CI 1.06 to 9.86). Prior HIV testing was negatively associated with reporting more condomless anal intercourse acts (past 2 months) (AOR=0.95, 95% CI 0.92 to 0.98) and greater internalised homophobia (AOR=0.92, 95% CI 0.86 to 0.99). Conclusions Our findings indicate an urgent need for expanded HIV testing services for MSM in Tijuana. Innovative, non-stigmatising, confidential HIV testing interventions targeted at young, less educated, migrant and non-gay identifying MSM may facilitate HIV testing and timely linkage to HIV care and treatment within this population.

    Variability and unpredictability are characteristics of the aquatic ecosystems, hydrological patterns and climate of the largely dryland region that encompasses the Basin and Range, American Southwest and western Mexico. Neither hydrological nor climatological models for the region are sufficiently developed to describe the magnitude or direction of change in response to increased carbon dioxide; thus, an attempt to predict specific responses of aquatic ecosystems is premature. Instead, we focus on the sensitivity of rivers, streams, springs, wetlands, reservoirs, and lakes of the region to potential changes in climate, especially those inducing a change in hydrological patterns such as amount, timing and predictability of stream flow. The major sensitivities of aquatic ecosystems are their permanence and even existence in the face of potential reduced net basin supply of water, stability of geomorphological structure and riparian ecotones with alterations in disturbance regimes, and water quality changes resulting from a modified water balance. In all of these respects, aquatic ecosystems of the region are also sensitive to the extensive modifications imposed by human use of water resources, which underscores the difficulty of separating this type of anthropogenic change from climate change. We advocate a focus in future research on reconstruction and analysis of past climates and associated ecosystem characteristics, long-term studies to discriminate directional change vs. year to year variability (including evidence of aquatic ecosystem responses or sensitivity to extremes), and studies of ecosystems affected by human activity. ?? 1997 by John Wiley & Sons, Ltd.

This cross-sectional study examines a subset of pre-intervention implementation data (n = 347) among families participating in the Child Health Initiative for Lifelong Eating and Exercise (CHILE) study conducted in rural New Mexico among predominantly Hispanic and American Indian Head Start centers. No significant relationships emerged between food insecurity and child overweight/obesity, certain feeding behaviors, or public food assistance utilization. Additional research is necessary to understand relationships between food insecurity and child overweight/obesity status, use of public assistance benefits, and certain feeding behaviors among rural preschool-aged children in predominantly Hispanic and American Indian communities.

    Purpose: Back pain is the leading cause of global years lived with disability. This cross-sectional study assessed if a greater exposure to smoking cigarettes was associated with a greater prevalence of back pain. Methods: This study examined data from 34,525 United States adults from the 2012 National Health Interview Survey. Analyses assessed the difference in back pain prevalence among current smokers, former smokers, and never smokers and the number of cigarettes smoked between current smokers with and without back pain. Results: Back pain prevalence was 28%. There was a significant association between back pain and smoking, X2 (2, 599, n = 34, 241) = 546.3, p < .001. Back pain increased with increased smoking exposure; back pain was present in 23.5% of never-smokers, 33.1% of former smokers, and 36.9% of current smokers. The number of cigarettes smoked per day for current daily smokers was higher for those with back pain (Md = 13) than those without back pain (Md = 10), U = 2701065, z = -3.70, p < .001, r = .05. Conclusions: Our findings suggest that there may be a biological gradient associated with exposure to smoking cigarettes and back pain in adult Americans. PMID:27790393

    A single particle soot photometer (SP2) was operated on the NCAR C-130 during the MIRAGE campaign (part of MILAGRO), sampling black carbon (BC) over Mexico. The highest BC concentrations were measured over Mexico City (sometimes as much as 2 Fg/m34 ) and over hill fires to the south of the city. The age of plumes outside of Mexico City was determined using a combination of HYSPLIT trajectories, WRF-FLEXPART modeling and CMET balloon tracks. As expected, older, diluted air masses had lower BC concentrations. A comparison of carbon monoxide (CO) and BC suggests a CO background of around 65 ppbv, and a backgroundcorrected BC/COnet ratio of 2.89±0.89 (ng/m39 -STP)/ppbv (average ± standard deviation). This ratio is similar for fresh emissions over Mexico City, as well as for aged airmasses. Comparison of light absorption measured with a particle soot absorption photometer (PSAP) and the SP2 BC suggests a BC mass-normalized absorption cross-section (MAC) of 10.9±2.1 m212 /g at 660 nm (or 13.1 m213 /g @ 550 nm, assuming MAC is inversely dependent on wavelength). This appears independent of aging and similar to the expected absorption cross-section for aged BC, but values, particularly in fresh emissions, could be biased high due to instrument artifacts. SP2-derived BC coating indicators show a prominent thinly-coated BC mode over the Mexico City Metropolitan Area (MCMA), while older air masses show both thinly-coated and thickly-coated BC. Some 2-day-old plumes do not show a prominent thickly-coated BC mode, possibly due to preferential wet scavenging of the likely-hydrophilic thickly-coated BC.

    We estimated the seroprevalences of varicella-zoster virus (VZV), herpes simplex virus (HSV) and cytomegalovirus (CMV) in this cross-sectional database study. Serum samples collected during the National Health and Nutrition survey (ENSANUT 2006) were obtained from subjects aged 1-70 years between January and October 2010. Serological assays for the determination of antibodies against VZV, HSV and CMV were performed. The overall seroprevalences of VZV, HSV-1, HSV-2 and CMV were 85.8%, 80.9%, 9.9% and 89.2%, respectively. Seroprevalences of VZV, HSV-1 and CMV were comparable between males and females. For HSV-2, although the seroprevalence rate was higher in females when compared to males, this difference in seroprevalence was not statistically significant. Seroprevalence rates for VZV, HSV-1, HSV-2 and CMV increased with age (p-value<.0001). Differences in seroprevalence rate for VZV by socioeconomic status (SES) were significant (p-value<0001). Results of the serological analyses reported high VZV seroprevalence, indicating high transmission in the Mexican population with children and adolescents at risk of acquiring VZV. Global HSV-1 seroprevalence was high, especially in adults. HSV-1 and HSV-2 seroprevalences were consistently higher in women than men, particularly for HSV-2. CMV seroprevalence was higher in Mexico when compared to developed countries. Seroepidemiological data on VZV supports the fact that varicella vaccination may serve as an alternative effective solution to reduce transmission in the Mexican population. For CMV and HSV, since no vaccines are available, activities to reduce transmission are important to reduce the risk of complications and therefore need to be considered.

    Decreased sleep duration and quality are associated with poor health. Given that Mexico-born US immigrants (MI) often have favorable health status relative to the general US population (USALL), we tested the hypothesis that MI have better sleep as compared to USALL and to Mexican-Americans (MA) born in the US. Cross-sectional analysis of a stratified multistage probability sample of 18 years and older civilian non-institutionalized USALL enrolled in NHANES during 2005-2006. Age-adjusted population prevalence rates and adjusted odd ratios of short habitual sleep time (SHST) and insomnia were calculated using weighted analyses. Computer assisted personal bilingual (English/Spanish) interviews in the participants' home using a sleep questionnaire. 5160 USALL participants, including 1046 MA, of whom 620 were MI. In logistic regression models unadjusted and adjusted for socioeconomic characteristics, health related behavior risk factors, health status, and depression, MI status was significantly associated with lower odds of SHST (OR = 0.7, 95%CI [0.6-0.9]), insomnia (OR = 0.3, 95%CI [0.2-0.5]), and sleep-associated functional impairments (OR = 0.4, 95%CI [0.2-0.8]). In MA males, MI status was associated with reduced odds of SHST < 7 h/weeknight and insomnia symptoms. Cultural changes measured by increased levels of English compared to Spanish language spoken at home were associated with an increased risk of poor sleep in MA men in univariate models, and may partially explain better sleep in MI men compared to their US-born counterparts. Compared to the general US poplulation, Mexican-born US immigrants have more favorable sleep, possibly contributing to their lower reported risk of diabetes, hypertension, CVD, and all-cause mortality (the "Hispanic Paradox").

    The availability of an adequate household food supply is critical for the older population. There is little work that has examined food security and the influence of nativity on food security among older Mexican Americans living along the Texas-Mexico border. Using data from 140 older women (age ≥ 50 y) who participated in the 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA), we examined demographic characteristics, health characteristics, food access and mobility, federal and community food and nutrition assistance programs, quality of food environment, food security, eating behaviors, and alternative food sources. 77% of participants experienced food insecurity, with 68% experiencing very low food security. Very low food security was associated with being born in Mexico, adjusting for household income and food assistance program participation. This article provides compelling evidence for enhanced research efforts that will better understand coping strategies and the use of food and nutrition assistance programs for reducing hardship associated with very low food security among older U.S.- and Mexico-born Mexican American women.

    Central America has been struck by at least 49 tsunamis between 1539 and 1996. As many as 37 of these events occurred at the Pacific Coast, and 31 were generated by earthquakes. Some of the events have been destructive, but despite this, tsunamis are an underrated hazard in Central America: people are not aware that they are at risk and even recent tsunami events have been forgotten. Recent studies, following the destructive tsunami occurred in Nicaragua in 1992, have revealed that Central America is a moderately tsunamigenic zone that is mainly affected by tsunamis triggered by earthquakes, especially at the Pacific coast where the Middle American Trench runs parallel to the coast. In this study, a statistical first and then a deterministic analysis for the Pacific coast of Central America has been carried out. The statistical approach aims to estimate the Gutenberg-Richter coefficients of the main seismic tsunamigenic regions of the area in order to assess the annual rate of occurrence of tsunamigenic earthquakes and their corresponding return period. A deterministic approach is then used to compute the tsunami run-up distribution along the coast corresponding to a given annual rate of occurrence of tsunamigenic earthquakes.

    To describe the prevalence of missing teeth, use of bridges and dentures and unmet dental needs among those aged 60 years and above. The associations of these conditions with socio-demographics, type 2 diabetes mellitus and depression were also studied. The work was carried out in 7 Latin American and Caribbean (LAC) cities in 1999-2000. A secondary analysis was conducted on the Survey of Health and Well-Being of Elders (SABE) dataset. The 7 cities were Buenos Aires, Bridgetown, São Paulo, Santiago, Havana, Mexico City and Montevideo. This survey did not employ any oral examinations. Descriptive statistics, chi-square and regression analysis were used to test for associations. Data for 10 902 persons were analyzed. Females made up 62% of the population. Across the SABE population, between 93.7% (Mexico City) to 99.9% (Santiago) reported missing teeth, with an average of 97.5%. Of those with missing teeth, between 55.1% (Mexico City) and 82.4% (São Paulo) reported having bridges or dentures, with an average of 70.1% across all SABE cities. The proportion of the SABE population with 'unmet dental needs' ranged from 85.8% (Santiago) to 98.4% (Havana), with an average of 94.5%. Bridgetown, São Paulo and Mexico City demonstrated a statistically significant association between aging and tooth loss. Generally a greater proportion of females (97.6%) reported tooth loss compared with males (96.8%), but in only São Paulo and Montevideo was there a statistically significant association between sex and tooth loss. Generally those with higher education reported less tooth loss, primary education (97.6% had tooth loss), secondary (96.8%) and tertiary (94.7%). All the SABE cities except Buenos Aires demonstrated a statistically significant association between tooth loss and education. The prevalence of missing teeth, use of bridges and dentures and unmet dental needs were high in the SABE cities in 1999-2000. In general across the SABE cities, the elderly with the most

    A clinic was established at Universidad de las Americas, Cholula, Puebla, Mexico for the study of acute diarrhea rates in newly-arrived students and full-time students. Diarrhea occurred in 22 of 55 newlly-arrived U.S. summer students (40%), compared to 28 of 142 U.S. full-time students (20%), 4 of 29 Venezuelan summer and full-time students (14%) and 7 of 66 Mexican full-time students (11%) (the differences were significant, p less than 0.005). Recurrent episodes of diarrhea during the month of study occurred in 15% of U.S. summer students, 4% of U.S. full-time students, and were non-existent in students from Latin America. As well as the 61 students with diarrhea enrolled in the incidence study, all students who developed diarrhea at the univeristy were encouraged to visit the clinic. This gave a total population of 130 cases of diarrhea. The illness that developed in students form the U.S. varied widely, but it typically consisted of seven to 13 unformed stools during the first 48 hours of illness, with illness persiting three to five days. Illness tended to be more severe in the U.S. students. Fifty per cent of the U.S. students with diarrhea had "severe" illness (greater than or equal to 10 unformed stools in first 48 hours) compared to 23% of the Latin Americans. This study indicates that the agents responsible for diarrhea in Latin America are widespread and that resistance to infection develops after prolonged or repeated exposure.

    2012-02-01

    The purpose of this article was to report identified barriers and challenges experienced in the recruiting process of Chinese American adolescents to a cross-sectional HIV/AIDS-related study. Snowball sampling method was used to recruit Chinese American adolescents from Chinese American communities in a U.S. Midwestern state. Barriers and challenges to recruitment were reviewed and analyzed from Chinese cultural perspectives in the hope of aiding researchers and health care providers understand and facilitate future recruitment of Chinese Americans for HIV/AIDS prevention studies. Barriers to recruitment were found related to the taboo topic of sexual issues in Chinese culture, unawareness and denial of HIV/AIDS risks, authoritarian parenting style in Chinese culture, and the required active consents. Facilitating factors of recruiting Chinese American adolescents to future HIV/AIDS prevention research or intervention programs are discussed. Information provided in this article may increase nurses' awareness of various barriers that they might encounter when they conduct research or address HIV/AIDS-related topics of Chinese American adolescents.

    TLALOCNet is a combined atmospheric and tectonic cGPS-Met network in Mexico designed for the investigation of climate, atmospheric processes, the earthquake cycle, and tectonics. While EarthScope-Plate Boundary Observatory (conterminous US, Alaska, Puerto Rico) is among the networks poised to become a nucleus for hemisphere-scale GPS observations, the completion of TLALOCNet at the end of 2015 will close a gap between PBO and other Latin American GPS networks that include COCONet (Central America, Caribbean, and Northern South America), CAnTO, CAP, and IGS extending from Alaska to Patagonia. The National Science Foundation funded the construction and operation of TLALOCNet, with significant matching funds and resources provided by the Universidad Nacional Autónoma de México (UNAM). The project will involve the construction or refurbishment of 38 cGPS-Met stations in Mexico built to PBO standards. The first three TLALOCNet stations were installed in the northern Mexican states of Sonora and Chihuahua in July 2014, following the North American Monsoon GPS Transect Experiment 2013. Together these observations better characterize critical components of water transport in the region. Data from these stations are now available through the UNAVCO data archive and can be downloaded from http://facility.unavco.org/data/dai2/app/dai2.html#. By the end of 2014, TLALOCNet data, together with complementary data from other regional cGPS networks in Mexico, will also be openly available through a Mexico-based data center. We will present the status of the project to date, including an overview of the station hardware, data communications, data flow, construction schedule, and science objectives. We will also present some of the challenges encountered, including regional logistics, shipping and importation, site security, and other issues associated with the construction and operation of a large continuous GPS network.

    This study aimed to estimate the prevalence of musculoskeletal (MSK) disorders and rheumatic diseases in the Chontal and Mixtec indigenous communities in the state of Oaxaca, Mexico, using the Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) methodology. After cross-culturally validating the COPCORD questionnaire for these communities, we conducted a cross-sectional, analytical, community-based census study using a house-to-house method. Positive cases of MSK disorders were assessed by primary care physicians and rheumatologists. The study population included participants aged ≥18 years from the indigenous communities of San Antonio Huitepec and San Carlos Yautepec. A total of 1061 persons participated in the study. Mean age was 46.9 years (standard deviation 19.9; age range 18-97 years); 642 (60.5 %) were women; 483 participants (45.5; 42.4-48.5 %) had MSK pain in the previous 7 days. Diagnoses were back pain 170 (16.0 %; 95 % confidence interval [CI] 13.8-18.3); osteoarthritis 157 (14.7 %; 95 % CI 12.7-17.0); rheumatic regional pain syndrome 53 (4.9 %; 95 % CI 3.7-6.4); rheumatoid arthritis 4 (0.3 %; 95 % CI 0.1-0.9); dermatomyositis 1 (0.09 %; 95 % CI 0.0-0.5); ankylosing spondylitis 1 (0.09 %; 95 % CI 0.0-0.5); systemic lupus erythematosus 1 (0.09 %; 95 % CI 0.02-0.5); and gout 1 (0.09 %; 95 % CI 0.0-0.5). 53.2 % had not received medical treatment for their disease. The prevalence of MSK disorders in indigenous communities in the Mixtec and Chontal regions is very high. The most common rheumatic diseases found were back pain and osteoarthritis. A high percentage of participants had not received medical care.

  2. Separate and unsanitary: African American women railroad car cleaners and the Women's Service Section, 1918-1920.

    PubMed

    Muhammad, Robin Dearmon

    2011-01-01

    The Women's Service Section (WSS) investigated federally controlled railroad stations and yards at the end of World War I. Few women worked in car cleaning before the war, and railroad management preferred to block women workers, especially African Americans, from gaining any kind of foothold in railroad work. African American women were the single largest group of railroad car cleaners during this period but they were routinely denied adequate facilities, including toilets, locker rooms, and dining facilities throughout the railroad system. By raising the issues of facilities, workers' rights, and public health, these women shaped federal policy and widened the agenda of the WSS to include a direct attack on segregated workplaces. This article argues that African American women car cleaners launched an industrial campaign that wove together concerns about racism, sexism, and health issues, and successfully removed barriers to women working in a predominately male industry.

  5. Could giardiasis be a risk factor for low zinc status in schoolchildren from northwestern Mexico? A cross-sectional study with longitudinal follow-up

    PubMed Central

    2010-01-01

    Background Both giardiasis and zinc deficiency are serious health problems worldwide. In Mexico, the prevalence of G. intestinalis was estimated at 32% in 1994. It remains a health problem in northwestern Mexico. Recent surveys (1987, 1995, and 1999) reported zinc deficiency in the Mexican population. The association of giardiasis and malabsorption of micronutrients has been well documented, although the association with zinc remains controversial. This study investigated the association between giardiasis and zinc deficiency in schoolchildren from northwestern Mexico. Methods We combined a cross-sectional design with a longitudinal follow-up six months after parasite treatment. The baseline sample consisted of 114 schoolchildren (mean age 8.8 yr) from seven suburban public schools, grouped as Giardia-free (n = 65, 57%) and Giardia-infected (n = 49, 43%). Three stool analyses per child were done using Faust's method. Children with giardiasis received secnidazole. Serum zinc was determined by atomic absorption spectrophotometry. Height and weight were measured. Socioeconomic information was obtained in an oral questionnaire, and daily zinc intake was assessed using 24 hour-recalls. Pearson's correlation and ANCOVA and paired t-test analyses were used to determine the association between giardiasis and zinc status. Results Longitudinal analysis demonstrated a significant increase of the mean serum zinc levels in the Giardia-infected group six months after treatment (13.78 vs. 19.24 μmol/L μmol/L; p = 0.001), although no difference was found between the Giardia-free and the Giardia-infected groups (p = 0.86) in the baseline analysis. Z scores for W/A and H/A were lower in the Giardia-infected than in the Giardia-free group (p < 0.05). No difference was observed in the socioeconomic characteristics and mean daily intakes of zinc between the groups (p > 0.05). Conclusions Giardiasis may be a risk factor for zinc deficiency in schoolchildren from northwestern Mexico

    The prevalence of diabetes is alarmingly high among Mexican American adults residing near the U.S.-Mexico border. Depression is also common among Mexican Americans with diabetes, and may have a negative influence on diabetes management. Thus, the purpose of the current study was to evaluate the associations of depression and anxiety with the behavioral management of diabetes and glycemic control among Mexican American adults living near the border. The characteristics of Mexican Americans with diabetes living in Brownsville, TX (N = 492) were compared by depression/anxiety status. Linear regression models were conducted to evaluate the associations of depression and anxiety with BMI, waist circumference, physical activity, fasting glucose, and glycated hemoglobin (HbA1c). Participants with clinically significant depression and/or anxiety were of greater age, predominantly female, less educated, more likely to have been diagnosed with diabetes, and more likely to be taking diabetes medications than those without depression or anxiety. In addition, anxious participants were more likely than those without anxiety to have been born in Mexico and to prefer study assessments in Spanish rather than English. Greater depression and anxiety were associated with poorer behavioral management of diabetes (i.e., greater BMI and waist circumference; engaging in less physical activity) and poorer glycemic control (i.e., higher fasting glucose, HbA1c). Overall, depression and anxiety appear to be linked with poorer behavioral management of diabetes and glycemic control. Findings highlight the need for comprehensive interventions along the border which target depression and anxiety in conjunction with diabetes management.

    An important goal of the Section on Tumors of the American Association of Neurological Surgeons (AANS) and Congress of Neurological Surgeons (CNS) since its founding in 1985 has been to foster both education and research in the field of brain tumor treatment. As one means of achieving this, the Section awards a number of prizes, research grants, and named lectures at the annual meetings of the AANS and CNS. After a brief examination of similar honors that were given in recognition of pioneering work by Knapp, Cushing, and other early brain tumor researchers, the authors describe the various awards given by the AANS/CNS Section on Tumors since its founding, their philanthropic donors, and the recipients of the awards. The subsequent career of the recipients is briefly examined, in terms of the rate of full publication of award-winning abstracts and achievement of grant funding by awardees.

    Improving coordination between primary care (PC) and secondary care (SC) has become a policy priority in recent years for many Latin American public health systems looking to reinforce a healthcare model based on PC. However, despite being a longstanding concern, it has scarcely been analyzed in this region. This paper analyses the level of clinical coordination between PC and SC experienced by doctors and explores influencing factors in public healthcare networks of Argentina, Brazil, Chile, Colombia, Mexico and Uruguay. A cross-sectional study was carried out based on a survey of doctors working in the study networks (348 doctors per country). The COORDENA questionnaire was applied to measure their experiences of clinical management and information coordination, and their related factors. Descriptive analyses were conducted and a multivariate logistic regression model was generated to assess the relationship between general perception of care coordination and associated factors. With some differences between countries, doctors generally reported limited care coordination, mainly in the transfer of information and communication for the follow-up of patients and access to SC for referred patients, especially in the case of PC doctors and, to a lesser degree, inappropriate clinical referrals and disagreement over treatments, in the case of SC doctors. Factors associated with a better general perception of coordination were: being a SC doctor, considering that there is enough time for coordination within consultation hours, job and salary satisfaction, identifying the PC doctor as the coordinator of patient care across levels, knowing the doctors of the other care level and trusting in their clinical skills. These results provide evidence of problems in the implementation of a primary care-based model that require changes in aspects of employment, organization and interaction between doctors, all key factors for coordination.

    A detailed bed-by-bed sampling within the Pimienta and the Lower Tamaulipas Formations from a section in the Apulco area (Puebla State, Eastern Mexico), allows the delimitation of the Jurassic/Cretaceous boundary. The Late Tithonian was identified by the presence of calpionellids of the Crassicollaria Zone (Colomi Subzone) and calcareous dinocysts of the Proxima Zone. The Tithonian/Berriasian boundary was placed at the acme of Calpionella alpina (small forms) between samples MZT 45-46. The Berriasian was divided into two main units, namely the Calpionella Zone, further subdivided into the Alpina, Ferasini and Elliptica subzones, and the Calpionellopsis Zone, within which only the Oblonga subzone was identified. The vertical distribution of calpionellids and their assemblages in the biozones of this Mexican section fit those from other Tethyan areas.

  5. The establishment of Central American migratory corridors and the biogeographic origins of seasonally dry tropical forests in Mexico

    Biogeography and community ecology can mutually illuminate the formation of a regional species pool or biome. Here, we apply phylogenetic methods to a large and diverse plant clade, Malpighiaceae, to characterize the formation of its species pool in Mexico, and its occupancy of the seasonally dry tropical forest (SDTF) biome that occurs there. We find that the ~162 species of Mexican Malpighiaceae represent ~33 dispersals from South America beginning in the Eocene and continuing until the Pliocene (~46.4–3.8 Myr). Furthermore, dispersal rates between South America and Mexico show a significant six-fold increase during the mid-Miocene (~23.9 Myr). We hypothesize that this increase marked the availability of Central America as an important corridor for Neotropical plant migration. We additionally demonstrate that this high rate of dispersal contributed substantially more to the phylogenetic diversity of Malpighiaceae in Mexico than in situ diversification. Finally, we show that most lineages arrived in Mexico pre-adapted with regard to one key SDTF trait, total annual precipitation. In contrast, these lineages adapted to a second key trait, precipitation seasonality, in situ as mountain building in the region gave rise to the abiotic parameters of extant SDTF. The timing of this in situ adaptation to seasonal precipitation suggests that SDTF likely originated its modern characteristics by the late Oligocene, but was geographically more restricted until its expansion in the mid-Miocene. These results highlight the complex interplay of dispersal, adaptation, and in situ diversification in the formation of tropical biomes. Our results additionally demonstrate that these processes are not static, and their relevance can change markedly over evolutionary time. This has important implications for understanding the origin of SDTF in Mexico, but also for understanding the temporal and spatial origin of biomes and regional species pools more broadly.

    Assess cross-sectional and prospective associations between food responsiveness and parental food control and anthropometric outcomes among American Indian children. Parents/caregivers completed psychosocial surveys and trained staff measured children's anthropometry at baseline (kindergarten) and at follow-up (1st grade) as part of a school-based obesity prevention trial (Bright Start). On/near the Pine Ridge Indian reservation. 422 child (51% female, mean age=5.8 years, 30% overweight/obese) and parent/caregiver (89% mothers) dyads. Two independent variables (child's Food Responsiveness and Parental Control scales) and six child anthropometric dependent variables (overweight status, body mass index z-score, % body fat, waist circumference, triceps skinfold, subscapular skinfold). Linear regression analyses, stratified by sex and adjusted for age and treatment condition. Baseline Food Responsiveness scale scores were positively associated with all six baseline anthropometric outcomes among boys (P's all <.01), but not girls. Parental Control scale scores were not significantly associated with outcomes and no prospective associations were statistically significant. Responsiveness to food may be associated with excess adiposity in young American Indian boys, however, the effects are not detectable over time. Obesity prevention programs for American Indian children may benefit by addressing eating without hunger among boys.

    Toxoplasma gondii (T. gondii) can be transmitted by blood transfusion. We determined the prevalence of T. gondii infection in healthy blood donors in Hermosillo city, Mexico, and the association of infection with T. gondii with the sociodemographic, clinical, and behavioral characteristics of blood donors. Four hundred and eight blood donors who attended two public blood banks in Hermosillo city were examined for anti-T. gondii IgG and IgM antibodies by using enzyme-linked immunoassays. Of the 408 blood donors (mean age 31.77 ± 9.52; range 18–60 years old) studied, 55 (13.5%) were positive for anti-T. gondii IgG antibodies, and 12 (21.8%) of them were also positive for anti-T. gondii IgM antibodies. Multivariate analysis showed that seropositivity to T. gondii was associated with age (OR = 1.74; 95% CI: 1.03–2.94; P = 0.03) and tobacco use (OR = 2.09; 95% CI: 1.02–4.29; P = 0.04). Seropositivity to T. gondii was correlated with the number of pregnancies, deliveries, and cesarean sections. The seroprevalence of T. gondii infection in blood donors in Sonora is the highest reported in blood donors in northern Mexico so far. This is the first report of an association of T. gondii exposure and tobacco use. Further research to confirm this association is needed. PMID:27446960

    Burnout syndrome is a three-dimensional clinical syndrome caused by stress at work. It is frequent in professions which require direct contact with people. In Mexico, the presence of Burnout Syndrome in doctors and medical students, is characterized as a threat to their health, quality of life and professional performance. To evaluate the prevalence of burnout syndrome in students of years 1 through 6 of medical school at a private university in northern Mexico. Cross-sectional study in the Escuela de Medicina Campus Laguna de la Universidad Autónoma de Durango. The one-dimensional scale of Burnout Student (EUBE) and the Maslach Burnout Inventory (MBI) were applied to the participants. SPSS 19 was used to analyze the data. Of the 344 students, 255 participated; 153 from years 1 to 3 (group 1); and 72 from years 4 to 6 (group 2). We found that 94.1% of the students of group 1 had mild burnout syndrome, and 2.8% had moderate burnout syndrome. In Group 2, 27.8% had moderate burnout syndrome, and 8.3% had severe burnout syndrome. The prevalence of severe burnout syndrome was higher in group 2 than in group 1 (p=0.02). Burnout syndrome affects medical students across all stages of their studies, and develops in a progressive way. In our study, external factors have no influence on the development of burnout syndrome.

    Introduction Medical students are a vulnerable group for the acquisition of blood borne pathogens due to their lack of experience. In Europe and Asia preventive training programs have reduced accidental exposures. Aim The aim of the study was to compare the lifetime prevalence of Needlestick and Sharp Objects Injuries (NSIs) among medical interns who received preventive training versus those without such training in Mexico City. Materials and Methods In 2013, a cross-sectional study was performed applying an anonymous self-administrated questionnaire. The study population included 467 medical students, male and female, at the end of their internship. The lifetime prevalence of NSI was estimated and compared between students who had received preventive training and those who did not. Results The overall lifetime prevalence of NSI was 58%. Lifetime prevalence was higher in students without preventive training compared to those who had such a training (68% vs 51%; p value= 0.002). NSI Lifetime prevalence was not associated with sex, age or place of birth. The task most commonly associated with the latest NSI in trained and untrained students was withdrawing blood. Conclusion NSI are frequent accidents among medical students in Mexico City, especially during blood taking. Training units on how to prevent NSI should be encouraged in Mexican medical colleges.

    Most of the recognized species of the genus Dionda inhabit drainages of the Gulf of Mexico from central Mexico to central Texas, USA, and have been considered a monophyletic group based on morphological, osteological, and allozyme investigations. Phylogenetic relationships of 15 species of Dionda and 34 species from closely related genera were inferred from one mitochondrial (cytb) and three nuclear gene sequences (S7, Rhodopsin, Rag1) totaling 4487 nucleotides. Separate analyses of all four genes yield congruent phylogenies; however the 15 putative species of Dionda evaluated were never recovered as a monophyletic group when species from nine related genera were included in the analyses. Among the ingroup taxa, one well-supported and highly divergent clade is consistently recognized and consists of six recognized and three undescribed northern species currently recognized in the genus Dionda. These nine species inhabit present or past tributaries of the Rio Grande basin of northern Mexico and southern USA, and were recovered as a basal clade in all analyses. Another large, also strongly supported clade, consisting of seven genera, include five southern recognized species currently in the genus Dionda, forming the sister group to the Codoma clade. These five species comprise the "Southern Dionda clade" and inhabit headwaters of the Pánuco-Tamesí drainage and some adjacent coastal rivers in the Tampico Embayment. The consistent and repeated identification of eight different clades recovered in most of the separate gene analyses strongly supports a division of the non-natural genus Dionda. A new genus, Tampichthys, is proposed for the clade of species endemic to east-central Mexico and formerly in Dionda. Tampichthys and the putative monotypic genus Codoma are more related to Mexican species of the genera Cyprinella and Notropis than to other species referred to Dionda sensu stricto.

    The absorption of short wave incoming solar radiation by the organic component of aerosols has been examined by using data from the MCMA-2003 and the 2006 MILAGRO field campaigns. Both field efforts took place in and around Mexico City. Single Scattering Albedo (SSA) was derived as a function of wavelength (300-870 nm) by combining irradiance measurements from a Multi-Filter Rotating Shadowband Radiometer (MFRSR) and spectrally resolved actinic flux measurements by spectroradiometry with a radiative transfer model (TUV). In addition, organic aerosol mass measured by a surface deployed aerodyne aerosol mass spectrometer was used to estimate the Mass Absorption Cross-section (MAC) of Organic Carbon (OC). It was found that the MAC for OC is about 10.5 m{sup 2}/g at 300 nm and falls close to zero at about 500 nm; these values are roughly consistent with previous MAC estimates of OC, and present first in-situ observations of this quantity.

    The number of Chinese Americans is growing and nearly 20% of older Chinese-American home care patients have at least one potentially inappropriate medications (PIMs) prescribed at hospital discharge. Further examination of PIMs during care transition is warranted, especially among older Chinese-Americans. To describe, during care transitions from hospital to home care: (i) the subtypes of PIMs, (ii) the difference of PIM prevalence prescribed at hospital discharge as compared to home care admission, (iii) the relationship between subtypes of PIMs, and (iv) issues affecting medication reconciliation among older Chinese-Americans. This cross-sectional, retrospective study was conducted in a large urban home care agency from June 2010 to July 2011. From data collected by in-home survey and chart abstraction, PIMs were identified using 2002 diagnosis-independent Beers criteria. The difference of PIM prevalence at hospital discharge and at home care admission was analyzed by Wilcoxon Signed Ranks test. The relationship between subtypes of PIMs was evaluated using Phi coefficient. 82 older (age 65 years and above) Chinese-American home care patients following recent hospital discharge. 3.38% (22) and another 3.72% (28) of prescribed medications were identified as PIMs at hospital discharge and home care admission, respectively. There was no statistically significant difference in PIM prevalence identified at hospital discharge and at homecare admission (z=-1.732, p=.083). PIMs included: long-term use of stimulant laxatives and high-dosages of ferrous sulfate, and a significant relationship between these two PIMS (r=.224, p=.04). More than 80% (n=65) of study participants reported low education levels and limited English proficiency. Subtypes of PIMs were ordered during the post-hospital transfers, indicating the necessity to review the appropriateness of medications during this transition. Guidelines such as Beer's criteria regarding appropriateness of medications should

In addition, thresholds for damage in the mouse intestine due to diagnostic pulses of ultrasound have been explored. The implications for human lung and intestinal exposure to clinical diagnostic ultrasound have not yet been determined. In this section, the data supporting the thresholds of petechial hemorrhage in these organ systems and the morphological observations will be reviewed. The potential mechanical mechanisms of damage to these organs due to diagnostic ultrasound also will be reviewed. Special attention will be given to the occurrence of inertial cavitation both in vitro and in vivo. The effects of ultrasound parameters, age, and species on the threshold for damage in animal models will be explored.

    There are significant disparities in breast cancer screening and survivorship between American Indian (AI) and non-Hispanic white women. This study aimed to identify the salient beliefs AI women from Oklahoma have on regular mammography screening, and to determine which beliefs and health- related practices are associated with past mammography screening behavior. This study used an integrated model of the Theory of Planned Behavior as the guiding theoretical framework. Data were collected from 255 (mean age = 51 years, SD 7.64 years) AI women randomly selected from a rural Oklahoma medical clinic (response rate: 79%). Multivariate logistic regression was used to identify factors associated with self-reported past mammography within the last two years while controlling for demographic variables. Associations were summarized using odds ratios (OR), the ratio of the odds of past mammography per a 1-unit increase in continuous independent factor scales (subjective physician norm, cultural affiliation, fatalism, knowledge of mammography screening guidelines, and perceived behavior control barriers) or between groups defined by categorical variables, and 95% confidence intervals (CI). Of the participants, 65% (n = 167) reported a screening mammogram within the last two years. After adjustment for age and educational status, women with a higher total subjective-norm physician score (OR = 1.15, 95% CI: 1.06-1.24), a higher knowledge of mammography screening guidelines (OR = 1.52, 95% CI: 1.00-2.31), a family history of breast cancer (OR = 9.97, 95% CI: 3.05-32.62), or reporting an annual versus none or a single physician breast examination (OR = 5.57, 95% CI: 1.79-17.37) had a higher odds of past mammography. On the other hand, women who were more culturally affiliated (OR = 0.42, 95% CI: 0.24-0.74), perceived more barriers (OR = 0.86, 0.78-0.94), or had higher fatalistic attitudes toward breast cancer (OR = 0.90, 95% CI: 0.82-0.99) had

    Endothelial dysfunction and arterial stiffness are early predictors of cardiovascular disease. Intervention studies suggest that diet is related to vascular health, but most prior studies tested individual foods or nutrients and relied on small samples of younger adults. The purpose of this study was to examine relations between adherence to the 2010 Dietary Guidelines for Americans and vascular health in a large, cross-sectional analysis. In 5887 adults in the Framingham Heart Study Offspring and Third Generation cohorts, diet quality was quantified with the 2010 Dietary Guidelines for Americans Index (DGAI-2010). Endothelial function was assessed via brachial artery ultrasound and arterial stiffness via arterial tonometry. In age-, sex-, and cohort-adjusted analyses, higher DGAI-2010 score (greater adherence) was modestly associated with lower resting flow velocity, hyperemic response, mean arterial pressure, carotid-femoral pulse wave velocity, and augmentation index, but not associated with resting arterial diameter or flow-mediated dilation. In multivariable models adjusting for cardiovascular risk factors, only the association of higher DGAI-2010 with lower baseline flow and augmentation index persisted (β=−0.002, P=0.003 and β=−0.05 ± 0.02, P<0.001, respectively). Age-stratified multivariate-adjusted analyses suggested that the relation of higher DGAI-2010 scores with lower mean arterial pressure, pulse wave velocity, and augmentation index was more pronounced among adults younger than 50 years. Better adherence to the 2010 Dietary Guidelines for Americans, particularly in younger adults, is associated with lower peripheral blood flow velocity and arterial wave reflection but not flow-mediated dilation. Our results suggest a link between adherence to the Dietary Guidelines and favorable vascular health. PMID:25885520

    To examine the prevalence of self-reported criminal and violent behavior, substance use disorders, and mental disorders among Mexican immigrants vis-à-vis the US born. Study findings are based on national data collected between 2012 and 2013. Binomial logistic regression was employed to examine the relationship between immigrant status and behavioral/psychiatric outcomes. Mexican immigrants report substantially lower levels of criminal and violent behaviors, substance use disorders, and mental disorders compared to US-born individuals. While some immigrants from Mexico have serious behavioral and psychiatric problems, Mexican immigrants in general experience such problems at far lower rates than US-born individuals.

    Aerial surveys of American White Pelicans (Pelecanus erythrorhynchos) were conducted over coastal Louisiana and the delta region of Mississippi on 1-2 days during December, February, and April each year from 1997 to 1999. Additional surveys were conducted in coastal Texas and Mexico during January 1998 and 1999. The numbers, location, and habitat of all pelicans observed were recorded. The coastal zone of Louisiana consistently had higher numbers of pelicans (18,000 to 35,000 birds) than other areas surveyed (3,000 to 8,000 birds), indicating that Louisiana may be the most important wintering area for American White Pelicans east of the Rocky Mountains. Among the four regions surveyed, the average size of pelican flocks was largest in Mississippi during January-February, particularly in 1999 (x?? = 245 birds/flock). Pelican numbers in Mississippi peaked in February but in Louisiana they were more variable. Pelicans in the delta region of Mississippi were found most often in fresh water and sand bar habitats during December, flooded field habitats during February, and catfish ponds in April. In Louisiana, pelicans used fresh, intermediate, and brackish marshes during December, but showed a preference for brackish and saline marshes in February and April.

    Background Lead (Pb) exposure during pregnancy may increase the risk of adverse maternal, infant, or childhood health outcomes by interfering with hypothalamic-pituitary-adrenal-axis function. We examined relationships between maternal blood or bone Pb concentrations and features of diurnal cortisol profiles in 936 pregnant women from Mexico City. Methods From 2007–11 we recruited women from hospitals/clinics affiliated with the Mexican Social Security System. Pb was measured in blood (BPb) during the second trimester and in mothers’ tibia and patella 1-month postpartum. We characterized maternal HPA-axis function using 10 timed salivary cortisol measurements collected over 2-days (mean: 19.7, range: 14–35 weeks gestation). We used linear mixed models to examine the relationship between Pb biomarkers and cortisol area under the curve (AUC), awakening response (CAR), and diurnal slope. Results After adjustment for confounders, women in the highest quintile of BPb concentrations had a reduced CAR (Ratio: −13%; Confidence Interval [CI]: −24, 1, p-value for trend < 0.05) compared to women in the lowest quintile. Tibia/patella Pb concentrations were not associated with CAR, but diurnal cortisol slopes were suggestively flatter among women in the highest patella Pb quantile compared to women in the lowest quantile (Ratio: 14%; CI: −2, 33). BPb and bone Pb concentrations were not associated with cortisol AUC. Conclusions Concurrent blood Pb levels were associated with cortisol awakening response in these pregnant women and this might explain adverse health outcomes associated with Pb. Further research is needed to confirm these results and determine if other environmental chemicals disrupt hypothalamic-pituitary-adrenal-axis function during pregnancy. PMID:24916609

A national cross-sectional survey from a sample of residents and fellows who completed an online bullying survey conducted in June 2015. The survey was distributed using a chain sampling method that relied on electronic referrals from 4,055 training programs, with 1,791 residents and fellows completing the survey in its entirety. Survey respondents completed basic demographic and programmatic information plus four general bullying and 20 specific bullying behavior questions. Between-group differences were compared for demographic and programmatic stratifications. Self-reported subjected to workplace bullying from peers, attendings, nurses, ancillary staff, or patients in the past 12 months. Almost half of the respondents (48%) reported being subjected to bullying although both those subjected and not subjected reported experiencing ≥ 1 bullying behaviors (95% and 39% respectively). Attendings (29%) and nurses (27%) were the most frequently identified source of bullying, followed by patients, peers, consultants and staff. Attempts to belittle and undermine work and unjustified criticism and monitoring of work were the most frequently reported bullying behaviors (44% each), followed by destructive innuendo and sarcasm (37%) and attempts to humiliate (32%). Specific bullying behaviors were more frequently reported by female, non-white, shorter than < 5'8 and BMI ≥ 25 individuals. Many trainees report experiencing bullying in the United States graduate medical education programs. Including specific questions on bullying in the Accreditation Council for Graduate Medical Education annual resident/fellow survey, implementation of anti-bullying policies, and a multidisciplinary approach engaging all stakeholders may be of great value to eliminate these pervasive behaviors in the field of healthcare.

    To determine the distribution and abundance of wintering plovers in the Laguna Madre of Texas and Tamaulipas, surveys were conducted in December 1997 and February 1998, along a 160 km stretch of barrier islands in Mexico and- 40 km of shoreline on South Padre Island, Texas. Altogether, 5,673 individuals, representing six plover species, were recorded during the surveys. Black-bellied Plovers Pluvialis squatarola were the most numerous (3 ,013 individuals) representing 53% of the total number of plovers observed. Numbers of Piping Charadriusm elodu, Snowy C . alexandrinus, Semipalmated C. semipalmatus and Wilson's Plovers C. wilsonia were 739, 1,345, 561, and 13 birds, respectively. Most individuals (97%) of all species except Wilson's Plovers were observed on bayside flats of the barrier islands. Similar numbers of Piping Plovers were recorded at South Padre Island, Texas, and in the Laguna Madre de Tamaulipas. Over 85% of the individuals of each of the other species were found in the more extensively surveyed Mexico portion of Laguna Madre. In Tamaulipas, most plover species were observed more often on algal flats than any other substrate. These results provide evidence of the value of these systems as wintering areas for plover species and indicate the need for more extensive survey efforts to determine temporal and spatial variation in the distribution of these species within the Laguna ecosystem.

    Conventional coronary artery disease risk factors might potentially explain at least 90% of the attributable risk of coronary artery disease. To better understand the association between the pre-industrial lifestyle and low prevalence of coronary artery disease risk factors, we examined the Tsimane, a Bolivian population living a subsistence lifestyle of hunting, gathering, fishing, and farming with few cardiovascular risk factors, but high infectious inflammatory burden. We did a cross-sectional cohort study including all individuals who self-identified as Tsimane and who were aged 40 years or older. Coronary atherosclerosis was assessed by coronary artery calcium (CAC) scoring done with non-contrast CT in Tsimane adults. We assessed the difference between the Tsimane and 6814 participants from the Multi-Ethnic Study of Atherosclerosis (MESA). CAC scores higher than 100 were considered representative of significant atherosclerotic disease. Tsimane blood lipid and inflammatory biomarkers were obtained at the time of scanning, and in some patients, longitudinally. Between July 2, 2014, and Sept 10, 2015, 705 individuals, who had data available for analysis, were included in this study. 596 (85%) of 705 Tsimane had no CAC, 89 (13%) had CAC scores of 1-100, and 20 (3%) had CAC scores higher than 100. For individuals older than age 75 years, 31 (65%) Tsimane presented with a CAC score of 0, and only four (8%) had CAC scores of 100 or more, a five-fold lower prevalence than industrialised populations (p≤0·0001 for all age categories of MESA). Mean LDL and HDL cholesterol concentrations were 2·35 mmol/L (91 mg/dL) and 1·0 mmol/L (39·5 mg/dL), respectively; obesity, hypertension, high blood sugar, and regular cigarette smoking were rare. High-sensitivity C-reactive protein was elevated beyond the clinical cutoff of 3·0 mg/dL in 360 (51%) Tsimane participants.

A cross-sectional study among 17,000 prisoners at 4 Mexico City prisons (June to December 2010). Participation was voluntary, confidential and based on informed consent. Participants were tested for HIV, Hepatitis B & C, syphilis, hypertension, obesity, and, if at risk, glucose and cholesterol. A subset completed a questionnaire on socio-demographic characteristics and risk behaviors. Positive results were delivered with counseling and treatment or referral. 76.8% (15,517/20,196) of men and 92.9% (1,779/1,914) of women participated. Complete data sets were available for 98.8%.

Obesity: 9.5% men, 33.8% women. Compared with national age- and sex-matched data, the relative prevalence was greater for HIV and syphilis among women, HIV and Hepatitis C in men, and all infections in younger participants. Obesity prevalence was similar for women and lower among male participants. The prevalence of previously diagnosed diabetes and hypertension was lower. Questionnaire data (1,934 men, 520 women) demonstrated lower educational levels, increased smoking and substance use compared to national data. High levels of non-sterile tattooing, physical abuse and histories of sexual violence were found.

    Background Mexico City prisons are characterized by overcrowded facilities and poor living conditions for housed prisoners. Chronic disease profile is characterized by low prevalence of self reported hypertension (2.5%) and diabetes (1.8%) compared to general population; 9.5% of male inmates were obese. There is limited evidence regarding on the exposure to prison environment over prisoner’s health status; particularly, on cardiovascular disease risk factors. The objective of this study is to assess the relationship between length of incarceration and selected risk factors for non-communicable chronic diseases (NCDs). Methods and Findings We performed a cross-sectional analysis using data from two large male prisons in Mexico City (n = 14,086). Using quantile regression models we assessed the relationship between length of incarceration and selected risk factors for NCDs; stratified analysis by age at admission to prison was performed. We found a significant negative trend in BMI and WC across incarceration length quintiles. BP had a significant positive trend with a percentage change increase around 5% mmHg. The greatest increase in systolic blood pressure was observed in the older age at admission group. Conclusions This analysis provides insight into the relationship between length of incarceration and four selected risk factors for NCDs; screening for high blood pressure should be guarantee in order to identify at risk individuals and linked to the prison’s health facility. It is important to assess prison environment features to approach potential risk for developing NCDs in this context. PMID:26381399

    Building up a scenario of Late Pleistocene-Holocene environmental change and human-landscape interactions in Central Mexico - one of the key areas for the natural and cultural history of America - requires development of local paleoenvironmental reconstructions. We studied the Tepexpan section at the edge of Texcoco a paleolake, near the mouth of Teotihuacan Valley as a multiproxy record of the environmental dynamics at the shore in the Basin of Mexico throughout the period of human occupation. The section is located in an ecotone affected by intensive and variable geomorphic processes and includes lacustrine, fluvial and volcanic sediments as well as paleosols. Our chronological scale is based on 6 AMS 14C dates from pollen concentrates and paleosol organic matter. The lower segment of the section dominated by the lacustrine sediments yielded pollen spectra; in the upper segment the record is based on the pedogenetic characteristics of paleosols. Different proxies agree in demonstrating the general trend (although some reversals are apparent) of decreasing effective moisture since MIS3: it is reflected first in the increase of herbaceous pollen after 27 ka BP, the decrease of lake level, the cessation of lacustrine sedimentation and beginning of marsh soil development at 10 ka BP and finally, the shift from hydromorphic to dryland semiarid pedogenesis in the Late Holocene. We assume that this trend was climatically controlled, whereas the deposition of sedimentary layers enriched with tephra are related to the pulses of volcanic activity; the pedosedimentary features associated with the upper soil are human-induced. Comparing the proposed scheme of environmental change with the archaeological record we propose that the initial settlers, Late Paleolithic hunters, could have utilized the wet swampy meadows which expanded on the Basin bottom as the lake level lowered and provided the niche for large herbivores during the Pleistocene-Holocene transition.

    In order to identify American ginseng and panax ginseng samples accurately and rapidly, the authors acquired the NIR spectra of the samples' cross-sections. Then the spectra were respectively analyzed according to the samples' physical structure factors and chemical factors. The authors selected appropriate bands and built a physical factor leading model, a chemical factors leading model as well as a comprehensive factor model. The authors found that all the three models' discriminant rates were above 96 percents, which can meet the needs of the rapid detection of raw Chinese medicinal crop materials. While the physical factors model had a simple operation, the discriminant rate was relatively low. The chemical factors model' discriminant rate was higher, but the computation is much more complex. Among the three models, the mixed factor model had the best result with the highest discrimination rate (100 percents) and a smaller number of principal components (4). The effect was the most ideal.

    The goal of this study was to compare American eel Anguilla rostrata life history in two inland river systems in Arkansas, U.S.A., that ultimately discharge into the Gulf of Mexico via the Mississippi River and the Red-Atchafalaya catchments. From 21 June 2011 to 24 April 2014, 238 yellow-phase A. rostrata were captured in the middle Ouachita River and tributaries using boat electrofishing and 39 in the lower White River using multiple sampling gears. Most of them were caught downstream of dams in both basins (61%). Medium-sized A. rostrata ranging from 225 to 350 mm total length (LT ) were the most abundant size group in the Ouachita River basin, but they were absent from the White River. Mean LT at age 4 years (i.e. youngest shared age) was 150 mm greater for the White River than the Ouachita River basin. Anguilla rostrata appeared to have a greater initial LT (i.e. minimum size upon arrival) in the White River that allowed them to reach a gonado-somatic index (IG ) of 1·5 up to 4 years earlier, and downstream migration appeared to occur 5 years earlier at 100 mm greater LT ; these differences may be related to increased river fragmentation by dams in the Ouachita River basin. Growth and maturation of A. rostrata in this study were more similar to southern populations along the Atlantic coast than other inland populations. Adult swimbladder nematodes Anguillicoloides crassus were not present in any of the 214 swimbladders inspected. Gulf of Mexico catchments may be valuable production areas for A. rostrata and data from these systems should be considered as range-wide protection and management plans are being developed. © 2016 The Fisheries Society of the British Isles.

  5. High Angle Reverse Faulting Along the Southwestern Coast of the Gulf of Mexico: An Example of Intraplate Deformation of the North American Plate

    The southwestern coast of the Gulf of Mexico shows a relatively high level of crustal seismicity compared to areas adjacent to it. Four relatively large earthquakes have occurred in this region for which an inversion of the focal mechanisms and hypocentral depths was possible. Suárez (2000) found two events for which a focal mechanism could be determined through the formal inversion of the P and S waves. The results showed that the earthquakes of 1959 in Jáltipan (M6.4) and 1973 near Veracruz (M5.3), share a similar focal mechanism: reverse faulting at a high angle with the axes of maximum compression oriented northwest to southeast. The focal depths are between 22 and 26 km deep. The focal mechanisms of two recent earthquakes were determined through the formal inversion of body waves. The 23 May 2007 event occurred beneath the coastal city of Alvarado and the 29 October 2009 took place offshore the north coast of the Gulf. The epicenter of the 2007 event (M5.4) is close to the 1973 Veracruz earthquake. The focal mechanism also shows high-angle reverse faulting and the focal depth is 26 km. This event has the same northeast to southwest direction of maximum compression as the other earthquakes in the area. The earthquake of 29 October 2007 (M5.2), offshore the city of Tuxpan, shows a strike slip focal mechanism with axes of maximum compression also oriented in a northeast to southwest direction, at a depth of 7 km. This shallow focal depth is in contrast with the deeper earthquakes to the south. These earthquakes reflect intraplate deformation of the North American plate. They do not seem to be caused by the extraction of oil in the Gulf of Mexico as they are far from the largest deposits now being exploited. The deformation appears to be related to a more regional compressional stress regime that induces faulting along the continental margin of the Gulf. We speculate that the deformation in the southwestern continental margin of the Gulf of Mexico may be caused

  6. Microfaunal evidence of age and depositional environments of the Cerro Prieto section (Plio-Pleistocene), Baja California, Mexico

    1982-01-01

    Microfossils including benthic and planktic foraminifera, ostracodes, calcareous algae, fish skeletal material, and fragments of pelecypods were found in 14 core samples from depths of 185 to 1952 m in the Cerro Prieto geothermal field, providing evidence of both the age and depositional history of sediments comprising the 3000-m-thick Pliocene and Pleistocene section in this area. Ostracodes of brackish water and marine origin constitute the most common microfossils present in this sequence occurring in 8 samples; in situ littoral and neritic species of benthic foraminifera occur in 5 samples with planktic species present in 2 samples. Distributional patterns of ostracodes and foraminifera together with previously analyzed lithofacies (Lyons and van de Kamp, 1980) indicate that the Cerro Prieto section represents an intertonguing complex of alluvial, deltaic, estuarine, and shallow marine environments deposited along the front of the Colorado River delta as it prograded across the Salton Trough during Pliocene and Pleistocene time. Foraminiferal evidence indicates that a sand and shale unit commonly present at depths between 700 and 1100 m represents a significant mid-Pleistocene marine incursion in the Cerro Prieto area. Tentative correlation of the Cerro Prieto section with the well dated Palm Springs Formation of the Imperial Valley, California area suggests that the Pliocene/Pleistocene boundary occurs at a depth of approximately 2000 m in the area of well M-93. Reworked specimens of Cretaceous foraminifera and fragments of the Cretaceous pelecypod Inoceramus were found in five samples further substantiating the Colorado Plateau provenance of a significant portion of the Colorado River deltaic sediments in the Cerro Prieto area.

  8. Recognition of cycle mechanisms from study of single section: Lessons learned in Madera Formation, Sandia Mountains, New Mexico

    Smith, G.A. )

    1989-09-01

    Eustasy, tectonics, and autogenic shoreline-related processes contribute to generation of transgressive-regressive (T-R) depositional cycles. Understanding the origin of a transgressive surface or a progradational sequence is critical for reconstructing paleogeography and predicting facies geometries. Knowledge of lateral extent and character of a cycle package provides the least ambiguous interpretation of the mechanism for changing shoreline position. In cases of poor exposure, low density of well data, or structural complexity, such interpretations must come from examination of single sections. This has been attempted during study of 300 m of cyclic carbonate/clastic sediments of the Pennsylvanian Madera Formation. There are 27 complete T-R cycles in the section, 15 in the lowest 120 m. The implied high frequency of the cycles (fourth order) implies that tectonism is less important than eustasy or autogenic processes in generating the cycles. Upward-coarsening delta-progradation sequences are rare. Most regressive sequences feature placement of delta-plain clastics on subtidal limestone without intervening delta-front or prodelta clastics. The uppermost meter of limestone shows evidence of abrupt shoaling; regressive grainstones underwent pervasive early cementation by meteoric waters. These relationships require that sea level fall. Most transgressive sequences exhibit ravinement surfaces with phosphate-bearing lags that truncate delta-plain facies and pass upward through thin transgressive grainstones to offshore lime mudstones. These may be of autogenic or eustatic origin. Few transgressive sequences show transitions from fluvial to shoreface clastics; transgression without diminished clastic input and accommodation of transgressive clastics would be favored by sea level rise. Most regressions appear to be eustatic, whereas the origin of most transgressions is ambiguous.

    Objective. This study was performed to determine the prevalence of and associated risk factors for cardiovascular disease (CVD) in Latin American (LA) patients with systemic lupus erythematosus (SLE). Methods. First, a cross-sectional analytical study was conducted in 310 Colombian patients with SLE in whom CVD was assessed. Associated factors were examined by multivariate regression analyses. Second, a systematic review of the literature on CVD in SLE in LA was performed. Results. There were 133 (36.5%) Colombian SLE patients with CVD. Dyslipidemia, smoking, coffee consumption, and pleural effusion were positively associated with CVD. An independent effect of coffee consumption and cigarette on CVD was found regardless of gender and duration of disease. In the systematic review, 60 articles fulfilling the eligibility criteria were included. A wide range of CVD prevalence was found (4%–79.5%). Several studies reported ancestry, genetic factors, and polyautoimmunity as novel risk factors for such a condition. Conclusions. A high rate of CVD is observed in LA patients with SLE. Awareness of the observed risk factors should encourage preventive population strategies for CVD in patients with SLE aimed at facilitating the suppression of cigarette smoking and coffee consumption as well as at the tight control of dyslipidemia and other modifiable risk factors.

    To describe how Spanish-speaking biomedical professionals in Latin America access and utilize bibliographic databases. Based on a MEDLINE search, 2 515 articles published between August 2002 and August 2003 were identified that dealt with and/or had authors from 16 countries: Argentina, Bolivia, Chile, Colombia, Costa Rica, Cuba, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, and Venezuela. The search was limited to references to basic science, clinical science, or social medicine. A survey was sent by e-mail to researchers who lived in 15 of the 16 countries (the exception being Nicaragua). The survey asked about the researcher's area of work (basic science, clinical science, or public health), the level of skill in using databases, the frequency and type of access to the databases most utilized, the impact from not having access to the full text of articles when preparing a manuscript, and how the respondent usually obtained the full-text version of articles. A total of 586 e-mail messages with the survey were sent out, and 185 responses were received (32%). The databases most utilized to obtain biomedical information were MEDLINE (34.1%), general search engines (Google, Yahoo!, and AltaVista) (15.9%), on-line journals (9.8%), BIREME-LILACS (6.0%), BioMedNet (5.4%), the databases of the Centers for Disease Control and Prevention of the United States of America (5.2%), and the Cochrane Library (4.9%). Of the respondents, 64% said they had average or advanced abilities in using MEDLINE. However, 71% of the respondents did not use or were not aware of the MEDLINE Medical Subject Headings (MeSH), a controlled vocabulary established by the National Library of Medicine of the United States of America for indexing articles. The frequency of accessing the databases was similar in all the countries studied, without significant differences in terms of the type of access (authorized access to commercial databases, unauthorized access to

    Education of volcanic hazards is a never-ending task in countries where volcanoes erupt very frequently as they do in the Latin American region (LAR). Eleven countries in the LAR have active volcanoes within their territories and some volcanoes are located in between countries so the volcanic hazards associated to the eruption of those volcanoes affect more than one country. Besides, countries without volcanoes within their territory (i. e. Belize, Honduras or Brazil) can be impacted as well. Personnel working at several volcano observatories in the LAR need training in Volcanology and, more importantly, in Volcanic Hazards. Unfortunately, Volcanology is a discipline that is not taught at universities of some countries. Even worse, Earth Sciences are not even taught at high education centers in some countries of the LAR. Thus, there is an important need for the acquisition of volcanological knowledge by the personnel working at volcano observatories but there are no possibilities for them to study at their countries or they are impended for travel abroad for training. The international course: "Curso de Vulcanología General" taught from Mexico City at the Universidad Nacional Autónoma de México (UNAM) has been successfully implemented and has been active over the last five years. Nearly 700 students have participated in this course although only ~150 have been awarded the certificate UNAM grants to the students who have concluded the course successfully. This course has been sponsored by UNAM, ALVO (Latin American Volcanological Association) and IAVCEI (International Association of Volcanology and Chemistry of the Earth's Interior). More than 50 lecturers from LAR, Europe and US have been involved in these courses. Here, Reflections on the course, the opportunities sparkled, the educational tools, benefits, statistics and virtues of the course are presented.

    Vaccination is a key current prophylactic measure for occupational risk of hepatitis B virus (HBV) infection. This study measures HBV vaccination coverage among health personnel in a Mexican hospital, and identifies factors associated with completion of the vaccination schedule. A cross-sectional study in workers of the Acapulco General Hospital, Mexico. Interviews documented vaccination history against HBV, number of doses received, and date of vaccination. Health workers with complete vaccination were considered those with at least three doses of vaccine received at intervals of two months between first and second doses, and six months to a year in the third dose. Some 52% of workers (436/834) reported at least one vaccination during their professional life and only 5.5% (46/834) completed the HBV vaccination schedule. Factors associated with completion were academic degree, perception of infection risk at work, and knowledge of vaccine efficacy and the need for a complete schedule. In line with hospitals in other studies, few hospital workers were fully vaccinated. Evidence from this study can inform efforts to increase HBV vaccination coverage.

    A cross-sectional survey for seropositivity to cysticercosis of pigs in the Yucatan Peninsula, Mexico, was carried out in 1996 together with a standardized questionnaire on predetermined individual pig and household risk factors for porcine infection. Serum samples from 697 pigs were analysed by immunoblot for antibodies to Taenia solium cysticercosis and questionnaires from 227 households in 18 villages were collected. All the data were analysed using multivariate analytical techniques taking household clustering into account. The overall porcine seroprevalence in the area was found to be 29%. The most important risk factors for seropositivity in pigs were presence versus absence of a toilet (adjusted odds ratio [adj. OR] 2.37, P = 0.005), crowded households (adj. OR 1.75, P = 0.034) and both corralling (adj. OR 2.14, P = 0.017) and letting pigs loose (adj. OR 2.32, P = 0.035) versus tying them up. There was evidence of clustering at household level and that possible risk factors at municipal or village level may also interact with higher risk management practices such as allowing pigs to run loose.

    Seepage investigations were conducted annually by the U.S. Geological Survey from 1988 to 1998 and from 2004 to 2013 along a 64-mile reach of the Rio Grande from below Leasburg Dam, Leasburg, New Mexico, to above American Dam, El Paso, Texas, as part of the Mesilla Basin monitoring program. Results of studies conducted from 2006 to 2013 are presented in this report. Seepage investigations were conducted over a period of 1–2 days in February of each year, during low-flow conditions in the non-irrigation season. During the seepage investigations, discharge was measured at as many as 24 sites along the Rio Grande and as many as 20 inflow sites within the study reach. Net seepage gain or loss was computed for each subreach by subtracting the discharge measured at the upstream location from the discharge measured at the closest downstream location along the river and then subtracting any inflow to the river within the subreach. An estimated gain or loss was determined to be significant when it exceeded the cumulative measurement uncertainty associated with the net seepage computation. Study reaches during 2006 to 2013 ranged from 20.2 to 64 miles in length, and seepage losses ranged from 8.2 ± 3.1 to 47.9 ± 8.2 cubic feet per second.

    The American oyster, Crassostrea virginica, is an important commercial species. Spawning occurs repeatedly during warmer months with millions of eggs released. Embryos and larvae are carried by currents throughout the estuaries and oceanic bays where they occur. The surviving larvae cement themselves to a solid object, where they remain for the remainder of life. Unable to move, they must tolerate changes in the environment that range from -2 to 36/sup 0/C (air temperature), 2 to 40 ppt salinity, and clear or muddy water. The density and occurrence of adults is limited by predators, chiefly oyster drills, whelks, fish, and crabs.

    Various studies have reported a direct association of cervical cancer risk with obesity and weight but not with the body fat percentage (BFP). The aim of this study was to analyze various anthropometric measures as potential risk factors for cervical cancer. A total of 20,236 women were included in a cross-sectional population-based survey. Obesity was defined according to the World Health Organization criteria, and central obesity was ≥80 cm; the BFP was defined using the Deurenberg equation (BFP = 1.2 [BMI] + 0.23 [age] - 10.8 [sex] - 5.4). The odds ratio (OR) was estimated from the chi square test and logistic regression models. The prevalence of cervical cancer increased from 514 (95% confidence interval [CI] 321, 707) and 680 (95% CI 494, 866) to 732 (95% CI 535, 928) per 100,000 inhabitants in subjects with a normal weight, subjects who were overweight and subjects who were obese, respectively. Moreover, an association between cervical cancer and BFP (OR 1.027; CI 95% 1.006, 1.048; p = 0.012) was observed, and the risk increased with a BFP ≥45% (OR 2.369; CI 95% 1.284, 4.369; p = 0.006). These data suggest a trend between the body mass index and the increasing prevalence of cervical cancer. In addition, the data showed a significant association between the BFP and cervical cancer, and this epidemiological association was higher as the BFP increased. Copyright © 2013 IMSS.

    Multilevel studies have gained importance for highlighting social inequalities in health. These associations have been reported previously in diseases such as arthritis and chronic pain. We conducted a cross-sectional study using multilevel analysis to identify individual and contextual factors associated with the variation of prevalence of osteoarthritis (OA) in the Mexican population. The sample included 17,566 individuals of which 10,666 (60.7%) were women. The relationship between individual and contextual factors and OA were analyzed with a multilevel strategy. From the total population, 1,681 individuals had OA. Multilevel analysis showed that individual variables such as female gender (odds ratio (OR) = 1.3, 95% confidence interval (CI) 1.1, 1.4), age range 55-65 years (OR = 1.6, 95% CI 1.3, 2.0), musculoskeletal pain in the last 7 days (OR = 2.6, 95% CI 2.3, 3.0), and use of pain treatments (OR = 1.4, 95% CI 1.2, 1.7) were associated with OA. At the regional level, the Social Gap Index (SGIx) was associated with the diagnosis of OA (coefficient 0.5, 95% CI 0.2-1.1). The SGIx contextual variable was positively associated with the regional prevalence of OA and the variation in prevalence of OA in different regions. The larger the social gap, the greater the variation in OA prevalence. These factors were independently associated with the prevalence of OA: female gender, pain intensity, physical limitation, and the use of pain treatments were individual variables associated with OA. The association between OA prevalence and regional variations with SGIx reflects inequities in health provisions that should be considered in health programs.

    This cross-sectional study assessed sexually transmitted infection (STI) prevalence, socio-demographic characteristics, substance use, sexual behaviors, and sexual network profiles among African American sexual minorities in Jackson, Mississippi. Bivariate chi-square tests and generalized estimating equation (GEE) models explored individual and partner-related factors. Compared to their heterosexual counterparts, male African American sexual minorities reported fewer sex partners (odds ratios [OR] 0.33, 95% confidence intervals [CI] 0.16-0.65) and lower concurrency levels (OR 0.42, 95%CI 0.24-0.72). African American sexual minority women reported greater substance abuse, more sex partners (OR 2.54, 95%CI 1.47-4.38), higher concurrency levels (OR 1.81, 95%CI 1.24-2.64), and more transactional sex (OR 2.52, 95%CI 1.25-5.11).

    To explore the founding of the American Medical Association's Section on Surgery in 1859 and how it represented, on a national basis, the beginnings of organized surgery and the formal start of the professionalization and specialization of surgery in the United States. The broad social process of organization, professionalization, and specialization that began for various disciplines in America in the mid-19th century was a reaction to emerging economic, political, and scientific influences including industrialization, urbanization, and technology. For surgeons or, at least, those men who performed surgical operations, the efforts toward group organization provided a means to promote their skills and restrict competition. An analysis of the published literature, and unpublished documents relating to the creation of the American Medical Association's Section on Surgery. During the 1850s and through the 1870s, a time when surgery was still not considered a separate branch of medicine, the organization of the American Medical Association's Section on Surgery provided the much needed encouragement to surgeons in their quest for professional and specialty recognition. The establishment of the American Medical Association's Section on Surgery in 1859 helped shape the nationwide future of the craft, in particular, surgery's rise as a specialty and profession.

Evidence from various studies has shown that higher body mass index (BMI) is a protective factor for bone mineral density (BMD). Most of the evidence, however, is from studies with Caucasian women and it is unclear to what extent ethnicity plays a role in modifying the effect of BMI on BMD.A cross sectional study was performed in which records of postmenopausal women who presented for screening for osteoporosis at 2 urban medical centres were reviewed. Using logistic regression, we examined the interaction of race and BMI after adjusting for age, family history of osteoporosis, maternal fracture, smoking, and sedentary lifestyle on BMD. Low BMD was defined as T-score at the lumbar spine < -1.Among 3,206 patients identified, the mean age of the study population was 58.3 +/- 0.24 (Years +/- SEM) and the BMI was 30.6 kg/m2. 2,417 (75.4%) were African Americans (AA), 441(13.6%) were Whites and 348 (10.9%) were Hispanics. The AA women had lower odds of having low BMD compared to Whites [Odds ratio (OR) = 0.079 (0.03-0.24) (95% CI), p < 0.01]. The odds ratio of low BMD was not statistically significant between White and Hispanic women. We examined the interaction between race and BMD. For White women; as the BMI increases by unity, the odds of low BMD decreases [OR = 0.9 (0.87-0.94), p < 0.01; for every unit increase in BMI]. AA women had slightly but significantly higher odds of low BMD compared to Whites [OR 1.015 (1.007-1.14), p <0.01 for every unit increase in BMI]. This effect was not observed when Hispanic women were compared to Whites.There is thus a race-dependent effect of BMI on BMD. With each unit increase in BMI, BMD increases for White women, while a slight but significant decrease in BMD occurs in African American women.

  8. Rifting and Subsidence in the Gulf of Mexico: Implications for Syn-rift, Sag, and Salt Sections, and Subsequent Paleogeography

    Thick (up to 5 km), rapid (<3 Ma), salt deposition is problematic for basin modelling because such accommodation cannot be thermal, yet GoM salt deposits (Late Callovian-Early Oxfordian) appear to be post-rift (most salt overlies planar sub-salt unconformities on syn-rift section). One possible solution is that the pre-drift GoM was a deep (~2 km) air-filled rift depression where basement had already subsided tectonically, and thus could receive up to 5 km of salt, roughly the isostatic maximum on exhumed mantle, hyper-thinned continent, or new ocean crust. ION-GXT and other seismic data along W Florida and NW Yucatán show that (1) mother salt was only 1 km thick in these areas, (2) that these areas were depositionally connected to areas of thicker deposition, and (3) the top of all salt was at global sea level, and hence the sub-salt unconformity along Florida and Yucatán was only 1 km deep by end of salt deposition. These observations fit the air-filled chasm hypothesis; however, two further observations make that mechanism highly improbable: (1) basinward limits of sub-salt unconformities along Florida/Yucatán are deeper than top of adjacent ocean crust emplaced at ~2.7 km subsea (shown by backstripping), and (2) deepest abyssal sediments over ocean crust onlap the top of distal salt, demonstrating that the salt itself was rapidly drowned after deposition. Study of global ION datasets demonstrates the process of "rapid outer marginal collapse" at most margins, which we believe is achieved by low-angle detachment on deep, landward-dipping, Moho-equivalent surfaces such that outer rifted margins are hanging walls of crustal scale half-grabens over mantle. The tectonic accommodation space produced (up to 3 km, < 3 Ma) can be filled by ~5 km of sag/salt sequences with little apparent hanging wall rifting. When salt (or other) deposition lags behind, or ends during, outer marginal collapse, deep-water settings result. We suggest that this newly identified, "outer

    The southern Taos Valley encompasses the physiographic and geologic transition zone between the Picuris Mountains and the San Luis Basin of the Rio Grande rift. The Embudo fault zone is the rift transfer structure that has accommodated the kinematic disparities between the San Luis Basin and the Española Basin during Neogene rift extension. The eastern terminus of the transfer zone coincides with the intersection of four major fault zones (Embudo, Sangre de Cristo, Los Cordovas, and Picuris-Pecos), resulting in an area of extreme geologic and hydrogeologic complexities in both the basin-fill deposits and the bedrock. Although sections of the Embudo fault zone are locally exposed in the bedrock of the Picuris Mountains and in the late Cenozoic sedimentary units along the top of the Picuris piedmont, the full proportions of the fault zone have remained elusive due to a pervasive cover of Quaternary surficial deposits. We combined insights derived from the latest geologic mapping of the area with deep borehole data and high-resolution aeromagnetic and gravity models to develop a detailed stratigraphic/structural model of the rift basin in the southern Taos Valley area. The four fault systems in the study area overlap in various ways in time and space. Our geologic model states that the Picuris-Pecos fault system exists in the basement rocks (Picuris formation and older units) of the rift, where it is progressively down dropped and offset to the west by each Embudo fault strand between the Picuris Mountains and the Rio Pueblo de Taos. In this model, the Miranda graben exists in the subsurface as a series of offset basement blocks between the Ponce de Leon neighborhood and the Rio Pueblo de Taos. In the study area, the Embudo faults are pervasive structures between the Picuris Mountains and the Rio Pueblo de Taos, affecting all geologic units that are older than the Quaternary surficial deposits. The Los Cordovas faults are thought to represent the late Tertiary to

    Introduction Little epidemiological evidence exists on alcohol or other substance use and related problems along the U.S.-Mexico border, although the border has been the focus of recent media attention related to the escalating drug/violence “epidemic”. The purpose of this study was to analyze the association of variables related to crossing the border (cross-border mobility) with three substance use outcomes reported for the last year: 1) heavy drinking (5+ drinks per day for men or 4+ for women), 2) alcohol use disorder (AUD), and 3) co-occurring heavy drinking and drug use (any use of illicit and/or non-medically prescribed drugs). Methods Household surveys were conducted, using area probability sampling of 1,565 Mexican-Americans residents, aged 18–65, living at the Texas-Mexico border in the metropolitan areas of Laredo and McAllen/Brownsville. Results Among those 18–29, more frequent crossing of the border was significantly predictive of AUD (OR=1.61, p<0.01) and co-occurring heavy drinking and drug use (OR=1.70, p<0.01). Staying more than one full day was predictive of AUD (OR = 3.07, p<0.001) and crossing to obtain over-the-counter or prescription drugs (“drug tourism”) or for nightlife/drinking were predictive of heavy drinking (ORs = 4.14, p<0.001; 3.92, p<0.01, respectively), AUD (ORs = 7.56, p<0.001; 7.68, p<0.01, respectively) and co-occurring heavy drinking and drug use (ORs = 8.53, p<0.01; 4.96, p<0.01, respectively). Among those 30–65, staying more than a full day and crossing for pharmaceutical reasons were predictive of heavy drinking (OR = 2.54, p<0.001; 2.61, p<0.05, respectively) and co-occurring heavy drinking and drug use (OR = 3.31, p<0.001; 4.86, p<0.01, respectively), while none of the mobility variables were predictive of AUD in this age group. Conclusions Cross-border mobility may play an important role in substance use and problems, especially among those 18–29. Findings also highlight the importance of “drug tourism

    Little is known about the strains of Trypanosoma cruzi circulating in Central America and specifically in the most important vector in this region, Triatoma dimidiata. Approximately six million people are infected with T. cruzi, the causative agent of Chagas disease, which has the greatest negative economic impact and is responsible for ~12,000 deaths annually in Latin America. By international consensus, strains of T. cruzi are divided into six monophyletic clades called discrete typing units (DTUs TcI-VI) and a seventh DTU first identified in bats called TcBat. TcI shows the greatest geographic range and diversity. Identifying strains present and diversity within these strains is important as different strains and their genotypes may cause different pathologies and may circulate in different localities and transmission cycles, thus impacting control efforts, treatment and vaccine development. To determine parasite strains present in T. dimidiata across its geographic range from Mexico to Colombia, we isolated abdominal DNA from T. dimidiata and determined which specimens were infected with T. cruzi by PCR. Strains from infected insects were determined by comparing the sequence of the 18S rDNA and the spliced-leader intergenic region to typed strains in GenBank. Two DTUs were found: 94% of infected T. dimidiata contained TcI and 6% contained TcIV. TcI exhibited high genetic diversity. Geographic structure of TcI haplotypes was evident by Principal Component and Median-Joining Network analyses as well as a significant result in the Mantel test, indicating isolation by distance. There was little evidence of association with TcI haplotypes and host/vector or ecotope. This study provides new information about the strains circulating in the most important Chagas vector in Central America and reveals considerable variability within TcI as well as geographic structuring at this large geographic scale.

    Seepage investigations have been conducted annually by the U.S. Geological Survey from 1988 to 1998 and from 2004 to the present (2014) along a 64-mile reach of the Rio Grande from below Leasburg Dam, Leasburg, New Mexico, to above American Dam, El Paso, Texas, as part of the Mesilla Basin monitoring program. Results of the investigation conducted in 2014 are presented in this report. The 2014 seepage investigation was conducted on February 11, 2014, during the low-flow conditions of the non-irrigation season. During the 2014 investigation, discharge was measured at 23 sites along the main-stem Rio Grande and 19 inflow sites within the study reach. Because of extended drought conditions affecting the basin, many sites along the Rio Grande (17 main-stem and 9 inflow) were observed to be dry in February 2014. Water-quality samples were collected during the seepage investigation at sites with flowing water as part of a long-term monitoring effort in the region.Net seepage gain or loss was computed for each subreach (the interval between two adjacent measurement locations along the river) by subtracting the discharge measured at the upstream location from the discharge measured at the closest downstream location along the river and then subtracting any inflow to the river within the subreach. An estimated gain or loss was determined to be meaningful when it exceeded the cumulative measurement uncertainty associated with the net seepage computation. The cumulative seepage loss in the 64-mile study reach in 2014 was 16.0 plus or minus 2.9 cubic feet per second.

    The 2010 Healthy Eating Index (HEI-2010), a measure of diet quality, is used to quantify adherence to the Dietary Guidelines for Americans. Better HEI scores have been associated with positive health outcomes; however, the relationship between diet quality and psychological resilience, a mental health attribute for coping with adversity, has not been assessed. The objective of the present study was to assess the relationship between diet quality and psychological resilience, and the relationship between resilience and demographics, anthropometrics, socioeconomic status, and health behavior. In this cross-sectional study, HEI-2010 scores and resilience were assessed using the Block food frequency questionnaire and the Connor-Davidson Resilience Scale. Other factors that can affect the relationship between HEI-2010 scores and resilience were assessed using surveys, and height and weight were measured to calculate body mass index. Male and female Army and Air Force recruits (n=834) enrolled in a randomized controlled trial and 656 (mean±standard deviation [SD] age=21±3.3 years) were included in this analysis. Data were collected before the initiation of military training at Fort Sill, OK (2012-2013) and Lackland Air Force Base, TX (2013-2014). Participants were split into low- and high-resilience groups based on Connor-Davidson Resilience Scale scores. Student's t test and χ(2) tests were used to determine differences between groups for continuous and categorical variables, respectively. Logistic regression was utilized to identify predictors of resilience. Better diet quality was associated with resilience; higher HEI predicted an increased likelihood (odds ratio=1.02; 95% CI 1.01 to 1.04) of a participant being in the high-resilience group after including race, ethnicity, education, smoking, age, body mass index, sex, and military branch in the full model. The data indicate that with every 10-point increase in HEI score, there was a 22% increased likelihood of

    Colorectal cancer (CRC) remains the most commonly diagnosed cancer among Korean Americans (KAs) in part due to low screening rates. Recent studies suggest that some KA patients engage in medical tourism and receive medical care in their home country. The impact of medical tourism on CRC screening is unknown. The purpose of this paper was to 1) investigate the frequency of medical tourism, 2) examine the association between medical tourism and CRC screening, and 3) characterize KA patients who engage in medical tourism. This is a community-based, cross-sectional study involving self-administered questionnaires conducted from August 2013 to October 2013. Data was collected on 193 KA patients, ages 50-75, residing in the Seattle metropolitan area. The outcome variable is up-to-date with CRC screening, defined as having had a stool test (Fecal Occult Blood Test or Fecal Immunochemical Test) within the past year or a colonoscopy within 10 years. Predictor variables are socio-demographics, health factors, acculturation, knowledge, financial concerns for medical care costs, and medical tourism. In multi-variate modeling, medical tourism was significantly related to being up-to-date with CRC screening. Participants who engaged in medical tourism had 8.91 (95% CI: 3.89-23.89) greater odds of being up-to-date with CRC screening compared to those who did not travel for healthcare. Factors associated with engaging in medical tourism were lack of insurance coverage (P = 0.008), higher levels of education (P = 0.003), not having a usual place of care (P = 0.002), older age at immigration (P = 0.009), shorter years-of-stay in the US (P = 0.003), and being less likely to speak English well (P = 0.03). This study identifies the impact of medical tourism on CRC screening and characteristics of KA patients who report engaging in medical tourism. Healthcare providers in the US should be aware of the customary nature of medical tourism among KAs and consider

    2014-08-01

    The taxonomic complexity of Crataegus (hawthorn; Rosaceae, Maleae), especially in North America, has been attributed by some to hybridization in combination with gametophytic apomixis and polyploidization, whereas others have considered the roles of hybridization and apomixis to be minimal. Study of the chemical composition and therapeutic value of hawthorn extracts requires reproducible differentiation of entities that may be difficult to distinguish by morphology alone. This study sought to address this by using the nuclear ribosomal spacer region ITS2 as a supplementary DNA barcode; however, a lack of success prompted an investigation to discover why this locus gave unsatisfactory results. ITS2 was extensively cloned so as to document inter- and intraindividual variation in this locus, using hawthorns of western North America where the genus Crataegus is represented by only two widely divergent groups, the red-fruited section Coccineae and the black-fruited section Douglasia. Additional sequence data from selected loci on the plastid genome were obtained to enhance further the interpretation of the ITS2 results. In the ITS2 gene tree, ribotypes from western North American hawthorns are found in two clades. Ribotypes from diploid members of section Douglasia occur in one clade (with representatives of the east-Asian section Sanguineae). The other clade comprises those from diploid and polyploid members of section Coccineae. Both clades contribute ribotypes to polyploid Douglasia. Data from four plastid-derived intergenic spacers demonstrate the maternal parentage of these allopolyploids. Repeated hybridization between species of section Douglasia and western North American members of section Coccineae involving the fertilization of unreduced female gametes explains the observed distribution of ribotypes and accounts for the phenetic intermediacy of many members of section Douglasia. © The Author 2014.

    Type 2 diabetes mellitus (T2DM) is one of the leading causes of death from worldwide non-communicable diseases. The prevalence of diabetes in the Mexico (MX)–United States border states exceeds the national rate in both countries. The economic burden of diabetes, due to decreased productivity, disability, and medical costs, is staggering and increases significantly when T2DM-related complications occur. The purpose of this study was to use a modified behavioral risk factor surveillance system (BRFSS) to describe the T2DM self-management behaviors, diabetes care, and health perception of a convenience sample of adults with T2DM in Monterrey, MX. This cross-sectional study design, with convenience sampling, was conducted with a convenience sample (n = 351) of adults in the metropolitan area of Monterrey, MX who self-reported a diagnosis of T2DM. Potential participants were recruited from local supermarkets. Twenty-six diabetes and health-related items were selected from the BRFSS and administered in face-to-face interviews by trained data collectors. Data analysis was conducted using descriptive statistics. The mean age was 47 years, and the mean length of time with T2DM was 12 years. The majority was taking oral medication and 34% required insulin. Daily self-monitoring of feet was performed by 56% of the participants; however, only 8.8% engaged in blood glucose self-monitoring. The mean number of health-care provider visits was 9.09 per year, and glycated hemoglobin level (HbA1c) was assessed 2.6 times per year. Finally, only 40.5% of the participants recalled having a dilated eye exam. We conclude the modified BRFSS survey administered in a face-to-face interview format is an appropriate tool for assessing engagement in T2DM self-management behaviors, diabetes care, and health perception. Extension of the use of this survey in a more rigorous design with a larger scale survey is encouraged. PMID:28512629

  10. Comparison of health-promoting behavior between Taiwanese and American adolescents: a cross-sectional questionnaire survey.

    The main aim of this study was to compare the health promotion practices of Taiwanese (n=265) and American (n=285) adolescents, using the revised Adolescent Health Promoting scale. A comparative and descriptive design was used. Categorical data analysis was applied to explore the association of culture differences and adolescent health-promoting behaviors. Findings indicated significant differences between Taiwanese and American adolescents in some demographic characteristics: American participants had higher self-perceived health status (p<0.001), parental educational level (p<0.001), overweight percentage (p<0.001), and rate of living only with the mother (p<0.001) than the Taiwanese participants. Taiwanese adolescents had a higher frequency of health-promoting behavior than Americans in terms of healthy diet behavior, stress management, health responsibility, and social support (p<0.01), but less frequently engaged in exercise and life appreciation (p<0.001). Because many of the demographic characteristics between the two countries, such as the parent's educational level, differ significantly, a comparison can be difficult. However, healthy behavior is an important measure of demand for preventive health services. The findings should sound an alarm for all public health professionals to take heed of what is happening to our youth based on culture differences. School and family health promotion counseling should be encouraged for adolescents to improve their lifestyle habits. Based on the findings, school health promotion programs should focus on factors for which there may be significant local ethnic differences. For the locales in this study, Taiwanese adolescents need encouragement to improve their exercise and life appreciation behaviors. For American adolescents, healthy diet, stress management, health responsibility, and social support should be emphasized.

  11. Deciphering Past and Present Tectonics of the Rio Grande Rift in New Mexico Utilizing Apatite Fission Track Thermochronology, Geochronology, Quaternary Faulting, and Cross-Section Restoration

    The Rio Grande rift provides an excellent laboratory for understanding styles and processes of extensional tectonics, and their driving forces. We apply apatite fission track (AFT) thermochronology, geochronology, fracture analysis, and cross-section restoration to decipher past and present tectonics of the Rio Grande rift. AFT data has been compiled from rift flank uplifts along the Rio Grande rift in an attempt to recognize long wavelength spatial and temporal patterns. AFT ages record time of cooling of rocks below ~110°C and, when cooling is due to exhumation, age elevation traverses can record upward advection of rocks through paleo 110°C isotherms. The relatively passive sides of half-grabens (e.g. Manzanos and Santa Fe Range) preserve Laramide AFT ages ranging from 45-70 Ma, indicating they were cooled during the Laramide Orogeny and have remained cooler than 110°C since then. Rift flanks on the tectonically active sides of half-grabens, (e.g. Sierra Ladrones, Sandias, Taos Range, and Sierra Blanca) have AFT ages that range from 35 Ma to <10 Ma, and record cooling that initiated with the Oligocene ignimbrite flare-up and continues through the Neogene. Our analysis tracks the approximate elevation of paleo 110°C isotherms in 10 Ma intervals from the Laramide to the present and shows that reconstructed paleoisotherms have been differentially uplifted, warped, and faulted since their time of formation, and hence serve as markers of uplift history and its mechanisms. AFT data at Ladron Peak, an active rift flank along the western margin of the Rio Grande rift in central New Mexico, indicates that it was rapidly unroofed between 20-10 Ma. Preliminary apatite helium data gives a similar age vs. elevation trend, but apatites have highly radiogenically damaged lattices and hence have corrected closure temperatures tens of degrees higher than AFT ages. The style of faulting at Ladron Peak is unusual because it is bounded by the anomalously low-angle (~15°) Jeter

  13. Sediment input pathways from North American highlands to the Gulf of Mexico based on detrital zircon U-Pb and U-Th/He dating

    The lower Miocene is a period of significant sediment input to the Gulf of Mexico (GOM) Basin that accompanied tectonic and climatic changes in North America. However, the resulting sediment pathways from continental upland sources to basinal sink remain poorly constrained. We employ detrital zircon (DZ) U-Pb and (U-Th)/He double dating to define both basement provenance and the exhumation histories of detrital source regions. We have collected samples from outcrops across the northern Gulf, from Texas to Florida, in order to discriminate sediment pathways. Most of our data show a mixture of source terranes, including Oligocene volcanic centers, Cordilleran Arc, Laramide uplifts, Grenville, Mid-Continent, Yavapai-Mazatzal, and Appalachian-Ouachita as major provinces and Wyoming and Superior regions as minor provinces. However, major DZ age peaks vary greatly between different samples, providing a means to differentia drainage systems. Five major sediment input pathways are defined: the Paleo-Rio Grande, Paleo-Red, Paleo-Mississippi and Paleo-Tennessee rivers and a local river system in Florida draining from Appalachians. The Paleo-Rio Grande and Paleo-Red rivers show a significant sediment input from Oligocene volcanic centers, Laramide uplift regions and the Cordilleran Arc, whereas the Paleo-Tennessee River received most of its sediments from Appalachian-Ouachita and Grenville basement. The Paleo-Mississippi River lies within a transitional zone between western and eastern North American drainage systems. By integrating (U-Th)/He ages we can further distinguish first order volcanic zircons from recycled zircons. This can increase the ability to discriminate different drainage systems because the recycled zircons come from source terranes that are different from the original basement in which they formed. For example, two different Grenville-age zircon sources are differentiated by our U-Pb and (U-Th)/He ages. Sediments in Texas show a mixed zircon source from

    During the American occupation of Japan (1945–1952), young public health officers from the US Army Medical Corps were posted in local US Army military government teams. These young doctors (aged 25 to 27 years), who had not absorbed the strong anti-Japanese tradition of the US military during World War II, seem to have alleviated the initial resentment felt by the Japanese toward the new governors of their homeland. The case of the Kyoto Military Government Team illustrates the Kyoto citizenry’s positive view of some American-directed public health measures. The team’s services helped to counter widely held negative views on colonialism, occupation, and public health; lessened resentment toward the unilateral command structure of the occupation forces; and contributed to improved relations between the United States and Japan at the local level.

    The work effort of prehistoric males relative to females has long been of interest to anthropologists, particularly in foraging versus farming groups. This knowledge requires a clear understanding of the sexual division of labor, or the dichotomy in subsistence roles allocated to males and females. Such research in the Prehispanic American Southwest has been limited. As previous work has shown that bone is the osseous template that reflects in vivo activity levels, it is possible to assess gender-based differences in past work effort using analyses of geometric properties of bone and calculations of bilateral asymmetry. Our research comparatively analyzed upper limb work effort by sex and subsistence in two skeletal samples from disparate economic groups, foragers and farmers, both from similar desert environments. The residentially mobile foragers are from the Lower Pecos region of southwest Texas and the farmers are from the aggregated pueblo of Pottery Mound in south central New Mexico. Humeri from 27 adult foragers (n = 11 males; n = 17 females) and 65 adult farmers (n = 38 males; n = 27 females) were selected for study. All humeri were radiographed and/or scanned and digitized. Statistical comparisons using two-way ANOVAs indicate that female farmers exhibited the greatest humeral strength and the least asymmetry. Relative to all other groups examined, female farmers engaged in higher levels of upper limb work effort implying a substantial economic contribution to their agricultural economy.

    To estimate the current age at menarche in 2 urban areas from Mexico and to analyze secular trends in the age at menarche in Mexico City. Cross-sectional survey and secondary data analyses. (1) Samples of female students from Mexico City and from the city of Xalapa; and (2) national health surveys. (1) Pre- and postmenarcheal students, aged 8-17 years; and (2) data for women born between 1904 and 1999 who grew up in Mexico City were obtained from 3 relevant national health surveys. (1) Students were asked if they had had their first period and when it occurred; (2) information on year of birth and age at menarche for the remaining women was obtained from the national surveys; data were divided in groups according to the decade in which the women were born. (1) The estimated mean age at menarche was 11.40 and 11.34 years in Mexico City and Xalapa respectively. (2) There were significant differences in age at menarche among women who were born in the different decades analyzed. Women who were born in the 1990s or later reported an earlier age at menarche than those who were born from the 1940s to 1980s (P < .0001). These results could be helpful to health and education professionals who should take into account that because there is currently a widening gap between the physical and psychosocial maturity of girls, they might need special support.

    2012-01-01

    Background Intestinal parasitism remains a public health challenge in northwestern Mexico even when a twice yearly single dose of albendazole (400 mg) is administered to schoolchildren. We aimed to determine the current prevalence of intestinal parasitic infections in schoolchildren of northwestern Mexico. Methods The Faust and Kato Katz techniques were used to detect and identify the intestinal parasite species. One thousand two hundred and seventy eight children from 12 public schools were invited to participate in this study; 312 children participated in September 2003. Results Sixty eight percent of the subjects had intestinal parasites, 63% had protozoan infections, and 29%, 16% and 10% were infected with Giardia duodenalis, Hymenolepsis nana, and Entamoeba histolytica/dispar/moshkovskii respectively. Fifty children excreted eggs of Hymenolepsis nana. Conclusion Educational strategies should be considered to support the national de-worming campaign, because albendazole alone will not sufficiently improve the health conditions of vulnerable populations.

    This environmental impact statement (EIS) addresses two proposed Federal actions, lease Sales 139 and 141, that will offer for lease Gulf of Mexico Outer Continental Shelf (OCS) areas that may contain economically recoverable oil and gas resources. The lease sales are proposed for 1992 and include lease blocks in the Central Gulf of Mexico Planning Area (CPA) and Western Gulf of Mexico Planning Area (WPA). Approximately 9700 blocks will be available for lease under the two proposed actions; only a small percentage is expected to be actually leased. On average, 432 blocks in the Central Gulf and 279 blocks in the Western Gulf have been leased in individual Gulf of Mexico OCS lease sales since 1984. Of the blocks that will be leased as a result of the two proposed actions, only a portion will be drilled and will likely result in subsequent production. The analytical methods used in this EIS have been formulated over a period of years and are based on the methodology outlined within the National Environmental Policy Act (NEPA). The first step of the analysis is the identification of significant environmental and socioeconomic resources through the scoping process. A range of impact levels is then defined for each of the significant resources to be analyzed. A range of energy resource estimates is derived from geologic and economic assumptions and a range of alternatives to the proposed action is established. Estimated levels of exploration and development actively are assumed for the purposes of the analysis. A scoping process was used to obtain information and comments on the proposed actions and the potential environmental effects from diverse interests, including the affected States, Federal agencies, the petroleum industry, environmental and public interest groups, and concerned individuals.

    Computer-assisted self-interviews were completed with a random sample of 163 unmarried Caucasian and African American men in a large metropolitan area. Almost a quarter (24.5%) of these men acknowledged committing an act since the age of 14 that met standard legal definitions of attempted or completed rape; an additional 39% had committed another type of sexual assault involving forced sexual contact or verbal coercion. An expanded version of the Malamuth et al. [1991] confluence model was examined using path analysis. The number of sexual assaults perpetrated by participants was associated with the direct or indirect effects of childhood sexual abuse, adolescent delinquency, alcohol problems, sexual dominance, positive attitudes about casual sexual relationships, and pressure from peers to engage in sexual relationships. Additionally, empathy buffered the relationship between sexual dominance and perpetration. The pattern of results was highly similar for African American and Caucasian men. The implications of these findings for sexual assault measurement are discussed and suggestions are made for alternative treatment programs. PMID:26435555

  8. [Fertility change in Mexico and the politics of population].

    PubMed

    Zavala De Cosio, M E

    1993-01-01

    This introduction to a detailed study of fertility change in Mexico assesses the available fertility data and describes the sources used, traces the beginning and course of the demographic transition in Mexico, and describes the work. Mexico's demographic transition began around 1930 with the acceleration of mortality decline. The considerable time lag between the mortality decline and the beginning of the fertility decline resulted in a period of very rapid growth. Between 1955 and 1975, the growth rate exceeded 3% annually. The start of the fertility decline dated to about 1970, the time of a major reform of population policy and creation of institutions to reduce growth. But the fertility decline was not solely the result of population programs. An incipient fertility decline could be observed in the metropolitan and more educated population sectors beginning in the early 1960s. The onset of the mortality decline in the 1930s resulted from the sustained social and economic progress made possible after the conclusion of the Mexican Revolution. Between 1930 and 1980, the adult illiteracy rate declined from 61.2% to 17%, while life expectancy increased from 33 years to 63.2 years. In Mexico as in other Latin American countries, the mortality decline, which disturbed the traditional balance between high mortality and high fertility, was the force setting off the demographic transition and the necessary precursor to fertility decline. The first of two main sections of the book focuses on examination of fertility variations in Mexico since around 1900 using cross-sectional and longitudinal methods of analysis. The second part describes the origins, history, and institutions involved in Mexico's population policies and the demographic programs and their principal results. The influence of population policies in demographic change is assessed, especially in the case of fertility changes induced by family planning programs. Both the first and second parts sought to place

    2015-05-01

    Chronic hepatitis B (HBV) in the Asian and Pacific Islander (API) American population is an under-recognized health issue in the United States. Among foreign-born API, the prevalence of HBV is approximately 10%. The prevalence in the general population is below 0.5%; among non-Hispanic whites it is below 0.2%. We examined beliefs held by the API populations in Rhode Island (RI) about personal HBV status and compared them with their actual HBV status. Of 59 total study participants, only 19 (32%) participants correctly knew their HBV status. Six (10%) participants were carriers of HBV; 18 (31%) lacked immunity to the virus. This pilot study suggests the RI API population is not knowledgeable about their own HBV status and are inadequately screened, vaccinated against, and treated for HBV. Increased statewide screening and education efforts, tailored to address this population, are needed to identify and inform those in need of medical attention or vaccination.

    To examine the association between household food insecurity (HFI) and risk of childhood stunting and to determine whether this association is modified by maternal-child overweight/obesity. Observational cross-sectional study. Data come from the Mexican National Health and Nutrition Survey (ENSANUT 2012 by its initials in Spanish), representative of rural and urban areas. Our study sample included 5087 mother-preschool child pairs and 7181 mother-schoolchild pairs. Differences in the prevalence (95% CI) of each HFI category by socioeconomic characteristics and maternal-child nutritional status were estimated. A logistic regression model was conducted for stunting and overweight among preschool children and for stunting and overweight/obesity among schoolchildren, adjusting for pertinent covariates. HFI was measured according to the Latin American and Caribbean Food Security Scale (ELCSA by its initials in Spanish). Weight and recumbent lenght or height measures were obtained from children. Overweight and obesity in women were determined according to the WHO Growth Reference Charts. The following covariates were included: sex of the child. urbanicity (urban/rural), region of residence and maternal education. Benefiting from food assistance programmes and socioeconomic status index were also included. Results were expressed as adjusted ORs. Stunting proved more prevalent in preschool children with moderate or severe HFI (16.2% and 16.8%, respectively) (p=0.036 and p=0.007, respectively) than in their counterparts with mild or no HFI (13.2% and 10.7%, respectively). Furthermore, the interaction between HFI and maternal obesity had a significant impact on stunting in preschool children (p<0.05). Severe HFI increased risk of stunting in children with non-obese mothers but not in those with obese mothers. We have discovered a new relationship between HFI and maternal obesity on the one hand and risk of childhood stunting on the other hand. This may reflect a shared

  16. Early Cretaceous to Paleocene North American Drainage Reorganization and Sediment Routing from Detrital Zircons: Significance to the Alberta Oil Sands and Gulf of Mexico Petroleum Provinces

    NASA Astrophysics Data System (ADS)

    Blum, M. D.

    2014-12-01

    Detrital zircons (DZs) represent a powerful tool for reconstructing continental paleodrainage. This paper uses new DZ data from Lower Cretaceous strata of the Alberta foreland basin, and Upper Cretaceous and Cenozoic strata of the Gulf of Mexico passive margin, to reconstruct paleodrainage and sediment routing, and illustrate significance to giant hydrocarbon systems. DZ populations from the Lower Cretaceous Mannville Group of Alberta and Saskatchewan infer a continental-scale river system that routed sediment from the eastern 2/3rds of North America to the Boreal Sea. Aptian McMurray Formation fluvial sands were derived from a drainage sourced in the Appalachians that was similar in scale to the modern Amazon. Albian fluvial sandstones of the Clearwater and Grand Rapids Formations were derived from the same Appalachian-sourced drainage area, which had expanded to include tributaries from the Cordilleran arc of the northwest US and southwest Canada. DZ populations from the Gulf of Mexico coastal plain complement this view, showing that only the southern US and Appalachian-Ouachita cordillera was integrated with the Gulf through the Late Cretaceous. However, by the Paleocene, drainage from the US Western Cordillera to the Appalachians had been routed to the Gulf of Mexico, establishing the template for sediment routing that persists today. The paleodrainage reorganization and changes in sediment routing described above played key roles in establishment of the Alberta oil sands and Gulf of Mexico as giant petroleum provinces. Early Cretaceous routing of a continental-scale fluvial system to the Alberta foreland provided large and contiguous fluvial point-bar sand bodies that became economically viable reservoirs, whereas mid- to late Cretaceous drainage reorganization routed greatly increased sediment loads to the Gulf of Mexico, which loaded the shelf, matured source rocks, and drove the gravitational and salt tectonics that helped establish the working hydrocarbon

  2. Financing of pediatric home health care. Committee on Child Health Financing, Section on Home Care, American Academy of Pediatrics.

    PubMed

    2006-08-01

    In certain situations, home health care has been shown to be a cost-effective alternative to inpatient hospital care. National health expenditures reveal that pediatric home health costs totaled $5.3 billion in 2000. Medicaid is the major payer for pediatric home health care (77%), followed by other public sources (22%). Private health insurance and families each paid less than 1% of pediatric home health expenses. The most important factors affecting access to home health care are the inadequate supply of clinicians and ancillary personnel, shortages of home health nurses with pediatric expertise, inadequate payment, and restrictive insurance and managed care policies. Many children must stay in the NICU, PICU, and other pediatric wards and intermediate care areas at a much higher cost because of inadequate pediatric home health care services. The main financing problem pertaining to Medicaid is low payment to home health agencies at rates that are insufficient to provide beneficiaries access to home health services. Although home care services may be a covered benefit under private health plans, most do not cover private-duty nursing (83%), home health aides (45%), or home physical, occupational, or speech therapy (33%) and/or impose visit or monetary limits or caps. To advocate for improvements in financing of pediatric home health care, the American Academy of Pediatrics has developed several recommendations for public policy makers, federal and state Medicaid offices, private insurers, managed care plans, Title V officials, and home health care professionals. These recommendations will improve licensing, payment, coverage, and research related to pediatric home health services.

    Understanding the breeding patterns of Aedes aegypti in households and the factors associated with infestation are important for implementing vector control. The baseline survey of a cluster randomised controlled trial of community mobilisation for dengue prevention in Mexico and Nicaragua collected information about the containers that are the main breeding sites, identified possible actions to reduce breeding, and examined factors associated with household infestation. This paper describes findings from the Mexican arm of the baseline survey. In 2010 field teams conducted household surveys and entomological inspections in 11,995 households from 90 representative communities in the three coastal regions of Guerrero State, Mexico. We characterized Ae. aegypti breeding sites and examined the effect of two preventive measures: temephos application in water containers, and keeping the containers covered. We examined associations with household infestation, using bivariate and multivariate analysis adjusted for clustering effects. We conducted entomological inspections in 11,995 households. Among 45,353 water containers examined, 6.5% (2958/45,353) were positive for larvae and/or pupae. Concrete tanks (pilas) and barrels (tambos) together accounted for 74% of pupal productivity. Both covering water containers and inserting temephos were independently associated with a lower risk of presence of larvae or pupae, with the effect of covering (OR 0.22; 95% CIca 0.15-0.27) stronger than that of temephos (OR 0.66; 95% CIca 0.53-0.84). Having more than four water containers was associated with household infestation in both rural areas (OR 1.42; 95% CIca 1.17-1.72) and urban areas (1.81; 1.47-2.25), as was low education of the household head (rural: 1.27; 1.11-1.46, and urban: 1.39; 1.17-1.66). Additional factors in rural areas were: household head without paid work (1.31; 1.08-1.59); being in the Acapulco region (1.91; 1.06-3.44); and using anti-mosquito products (1.27; 1

  11. Stability of salt in the Permian salt basin of Kansas, Oklahoma, Texas and New Mexico, with a section on dissolved salts in surface water

    The Permian salt basin in the Western Interior of the United States is defined as that region comprising a series of sedimentary basins in which halite and associated salts accumulated during Permian time. The region includes the western parts of Kansas, Oklahoma, and Texas, and eastern parts of Colorado and New Mexico. Following a long period of general tectonic stability throughout the region during most of early Paleozoic time, there was much tectonic activity in the area of the Permian salt basin during Late Pennsylvanian and Early Permian time just before bedded salt was deposited. The Early Permian tectonism was followed by stabilization of the basins in which the salt was deposited. These salt basins were neither contemporaneous nor continuous throughout the region, so that many salt beds are also discontinuous. In general, beds in the northern part of the basin (Kansas and northern Oklahoma) are older and the salt is progressively younger towards the south. Since Permian time the Permian salt basin has been relatively stable tectonically. Regionally, the area of the salt basin has been tilted and warped, has undergone periods of erosion, and has been subject to a major incursion of the sea; but deep-seated faults or igneous intrusions that postdate Permian salt are rare. In areas of the salt basin where salt is near the surface, such as southeastern New Mexico and central Kansas, there are no indications of younger deep-seated faulting and only a few isolated igneous intrusives of post-Permian age. On the other hand, subsidence or collapse of the land surface resulting from dissolution has been commonplace in the Permian salt basin. Some dissolution of salt deposits has probably been taking place ever since deposition of the salt more than 230 million years ago. Nevertheless, the subsurface dissolution fronts of the thick bedded-salt deposits of the Permian basin have retreated at a very slow average rate during that 230 million years. The preservation of

    The Latin American (LA) population resident in the USA is a growing subgroup of the population. To find out the structure of attitude towards organ donation in the LA population resident in Florida (USA). A sample was taken of LA residents in Florida, randomized and stratified by nationality, age and sex (n = 1524). Attitude was assessed using a validated questionnaire (PCID-DTO Rios) that was self-completed anonymously. The survey completion rate was 95% (n = 1450). Attitude was favourable in 33% of respondents (n = 485), against in 40% (n = 575) and undecided in 27% (n = 390). The following variables were associated with a favourable attitude: country of origin (Dominican Republic; P = 0.038); sex (female; P < 0.001); marital status (married; P < 0.001); level of education (university; P < 0.001); previous experience of the subject (P < 0.001); considering the need for a transplant in the future (P < 0.001); understanding the concept of brain death (P = 0.003); attitude towards donating a family member's organs (P < 0.001); having discussed organ donation and transplantation with one's family (P < 0.001) or with one's partner (P < 0.001); participation in pro-social type activities (P < 0.001); the respondent's religion (atheist-agnostic; P < 0.001); a respondent's knowledge of the attitude of his or her religion towards organ donation (P < 0.001); no concern about mutilation after donation (P < 0.001); acceptance of cremation (P < 0.001); burial (P < 0.001); and an autopsy if one were needed (P < 0.001). The attitude towards donation of LA in Florida is worse than that reported in the native population and is associated with certain psychosocial factors. © 2017 Steunstichting ESOT.

    2012-01-01

    Background The food group intake patterns of low income Hispanic and African American preschool children are not well documented. The aim of this study was to perform a food group intake analysis of low income minority preschool children and evaluate how macronutrient and micronutrient intake compares to Dietary Reference Intakes (DRI). Methods A cross sectional study design using three-day food diaries analyzed by dietary analysis software (Nutrient Database System for Research) was used. Children were recruited from well-child clinics at Children’s Healthcare of Atlanta at Hughes Spalding and North Dekalb Grady Satellite Clinic, Atlanta, GA. Low-income, African American and Hispanic preschool age children (n = 291) were enrolled. A total of 105 completed and returned the 3-day food diaries. Chi-squared tests were used to assess demographic variables. The mean percentage of intake per day of specific food groups and sub-groups were obtained (servings of given food group/total daily servings). Food intake data and proportion of children meeting DRIs for macro- and micronutrients were stratified by race/ethnicity, nutritional status, and caloric intake, and were compared using t-tests. Regression models controlling for age, BMI and sex were obtained to assess the effect of total caloric intake upon the proportional intake of each studied food group. Results The mean age of African American children was 2.24 ± 1.07 years and Hispanic children 2.84 ± 1.12 years. African Americans consumed more kcal/kg/day than Hispanics (124.7 ± 51 vs. 96.9 ± 33, p < 0.05). Hispanics consumed more fruits (22.0 ± 10.7% vs. 14.7 ± 13.7%, p < 0.05), while African Americans consumed more grains (25.7 ± 7.8% vs. 18.1 ± 6.4%, p < 0.05), meats (20.7 ± 9.0% vs. 15.4 ± 6.1%, p < 0.05), fats (9.8 ± 5.4% vs. 7.0 ± 5.8%, p < 0.05), sweet drinks (58.7 ± 17.1% vs. 41.3 ± 14.8%, p < 0.05) and low

    The issue of access to health care for the elderly and the quality of that care is of growing importance not only in the United States but also in less developed nations such as Mexico. An area of special interest is the U.S.-Mexico border region, where an increasing number of people are relocating to seek jobs they believe will open up as the North American Free Trade Agreement (NAFTA) loosens trade barriers. Workers flocking to the border often bring their families, including elderly relatives. This study examines a sample of lower-middle and mid-middle class Mexicans aged sixty to eighty-nine who reside in the border city of Ciudad Juárez, focusing on the principal ailments which affect these individuals and available treatment. A concluding section makes brief comparative remarks on access to health care for the elderly in Mexico and in the United States.

    To examine the patterns of family dynamics that are most associated with the mental health of traumatic brain injury (TBI) caregivers from Mexico. It was hypothesized that healthier family dynamics would be associated with better caregiver mental health. A cross-sectional study of self-reported data collected from TBI caregivers through the Mexican National Institute of Rehabilitation in Mexico City, Mexico, the premier public medical facility in Mexico that provides rehabilitation services to patients with various disabilities. One public outpatient medical and rehabilitation facility. Sixty-eight caregivers of individuals with moderate-to-severe TBI from Mexico City, Mexico, were related to an individual with TBI who was ≥3 months after injury, a primary caregiver for ≥3 months, familiar with the patient's history, and without neurologic or psychiatric conditions. The average (standard deviation) age of caregivers was 50.94 ± 12.85 years), and 82% were women. The caregivers completed Spanish versions of instruments that assessed their own mental health and family dynamics. Outcomes assessed included family dynamics (Family Adaptability and Cohesion Evaluation Scale-Fourth Edition; Family Communication Scale; Family Satisfaction Scale; Family Assessment Device-General Functioning; and Relationship-Focused Coping Scale), and caregiver mental health (Patient Health Questionnaire-9, Zarit Burden Interview, and Satisfaction with Life Scale). Results of canonical correlation analyses suggested that caregiver mental health and family dynamics were positively related, with a large effect size. Caregivers with high family satisfaction and cohesion tended to have a low burden and high satisfaction with life. In addition, caregiver depression and burden were positively related to each other and were both inversely related to caregiver satisfaction with life. TBI caregiver interventions in Latino populations would likely benefit from including programming or

    The idiopathic inflammatory demyelinating disease (IIDD) spectrum has been investigated among different populations, and the results have indicated a low relative frequency of neuromyelitis optica (NMO) among multiple sclerosis (MS) cases in whites (1.2%-1.5%), increasing in Mestizos (8%) and Africans (15.4%-27.5%) living in areas of low MS prevalence. South America (SA) was colonized by Europeans from the Iberian Peninsula, and their miscegenation with natives and Africans slaves resulted in significant racial mixing. The current study analyzed the IIDD spectrum in SA after accounting for the ethnic heterogeneity of its population. A cross-sectional multicenter study was performed. Only individuals followed in 2011 with a confirmed diagnosis of IIDD using new diagnostic criteria were considered eligible. Patients’ demographic, clinical and laboratory data were collected. In all, 1,917 individuals from 22 MS centers were included (73.7% female, 63.0% white, 28.0% African, 7.0% Mestizo, and 0.2% Asian). The main disease categories and their associated frequencies were MS (76.9%), NMO (11.8%), other NMO syndromes (6.5%), CIS (3.5%), ADEM (1.0%), and acute encephalopathy (0.4%). Females predominated in all main categories. The white ethnicity also predominated, except in NMO. Except in ADEM, the disease onset occurred between 20 and 39 years old, early onset in 8.2% of all cases, and late onset occurred in 8.9%. The long-term morbidity after a mean disease time of 9.28±7.7 years was characterized by mild disability in all categories except in NMO, which was scored as moderate. Disease time among those with MS was positively correlated with the expanded disability status scale (EDSS) score (r=0.374; p=<0.001). This correlation was not observed in people with NMO or those with other NMO spectrum disorders (NMOSDs). Among patients with NMO, 83.2% showed a relapsing-remitting course, and 16.8% showed a monophasic course. The NMO-IgG antibody tested using indirect

Population-based household surveys in rural and urban catchment areas in Peru, Mexico and China. Participating households were selected from all households with older residents. Descriptive analyses were weighted back for sampling fractions and non-response. Household income and consumption were estimated from a household key informant interview. 877 Household interviews (3177 residents). Response rate 68 %. Household income and consumption correlated plausibly with other economic wellbeing indicators. Household Incomes varied considerably within and between sites. While multigenerational households were the norm, older resident's incomes accounted for a high proportion of household income, and older people were particularly likely to pool income. Differences in the coverage and value of pensions were a major source of variation in household income among sites. There was a small, consistent inverse association between household pension income and labour force participation of younger adult co-residents. The effect of pension income on older adults' labour force participation was less clear-cut. Historical linkage of social protection to formal employment may have contributed to profound late-life socioeconomic inequalities. Strategies to formalise the informal economy, alongside increases in the coverage and value of non-contributory pensions and transfers would help to address this problem.

    Living near landfills is a known health hazard prompting recognition of environmental injustice. The study aim was to compare self-reported symptoms of ill health among residents of four neighborhoods, living in haphazardly constructed settlements surrounded by illegal dumpsites in Tijuana, Mexico. One adult from each of 388 households located in Los Laureles Canyon were interviewed about demographics, health status, and symptoms. Distance from each residence to both the nearest dumpsite and the canyon bottom was assessed. The neighborhoods were selected from locations within the canyon, and varied with respect to proximity to dump sites. Residents of San Bernardo reported significantly higher frequencies of ill-health symptoms than the other neighborhoods, including extreme fatigue (OR 3.01 (95% CI 1.6–5.5)), skin problems/irritations (OR 2.73 (95% CI 1.3–5.9)), stomach discomfort (OR 2.47 (1.3–4.8)), eye irritation/tears (OR 2.02 (1.2–3.6)), and confusion/difficulty concentrating (OR 2.39 (1.2–4.8)). Proximity to dumpsites did not explain these results, that varied only slightly when adjusted for distance to nearest dumpsite or distance to the canyon bottom. Because San Bernardo has no paved roads, we hypothesize that dust and the toxicants it carries is a possible explanation for this difference. Studies are needed to further document this association and sources of toxicants. PMID:25226411

    Researchers examining the relationships between traditional medicine and biomedicine have observed two conflicting tendencies. Some suggest that the use of biomedicine and biomedical concepts displaces the use of traditional medicine and medical beliefs. Other scholars have found that traditional medicine and biomedicine can co-exist, complement, and blend with each other. In this paper we use an econometric model and quantitative data to test the association between individual knowledge of pharmaceuticals and individual knowledge of medicinal plants. We use data from a survey among 136 household heads living in a rural indigenous community in Oaxaca, Mexico. Data were collected as a part of long term fieldwork conducted between April 2005 and August 2006 and between December 2006 and April 2007. We found a significant positive association between an individual's knowledge of medicinal plants and the same individual's knowledge of pharmaceuticals, as well as between her use of medicinal plants and her use of pharmaceuticals. We also found a negative association between the use of medicinal plants and schooling. Our results suggest that, in the study site, individual knowledge of medicinal plants and individual knowledge of pharmaceuticals co-exist in a way which might be interpreted as complementary. We conclude that social organization involved in the use of medicines from both traditional medicine and biomedicine is of particular significance, as our findings suggest that the use of pharmaceuticals alone is not associated with a decline in knowledge/use of medicinal plants.

    -Results of the American College of Surgeons Oncology Group Z0011 trial showed that patients with early-stage breast cancer and limited sentinel node metastasis treated with breast conservation and systemic therapy did not benefit from axillary lymph node dissection. Subsequently, most pathology departments have likely seen a decrease in frozen section diagnosis of sentinel lymph nodes. -To determine the effect of the Z0011 trial on pathology practice and to examine the utility of intraoperative sentinel lymph node evaluation for this subset of patients. -Pathology reports from cases of primary breast cancer that met Z0011 clinical criteria and were initially treated with lumpectomy and sentinel lymph node biopsy from 2009 to 2015 were collected. Clinicopathologic data were recorded. -Sentinel lymph node biopsies sent for frozen section diagnosis occurred in 22 of 22 cases (100%) in 2009 and 15 of 22 cases (68%) in 2010 during the pre-Z0011 years, and in 3 of 151 cases (2%) collected in 2011 through 2015, considered to be post-Z0011 years. Of the 151 post-Z0011 cases, 28 (19%) had sentinel lymph nodes with metastasis, and 147 (97%) were spared axillary lymph node dissection. -Following Z0011, intraoperative sentinel lymph node evaluation has significantly decreased at our institution. Prior to surgery, all patients had clinically node-negative disease. After sentinel lymph node evaluation, 97% (147 of 151) of the patients were spared axillary lymph node dissection. Therefore, routine frozen section diagnosis for sentinel lymph node biopsies can be avoided in these patients.

    The City of Albuquerque, New Mexico, is interested in gaining a better understanding, both quantitative and qualitative, of the aquifer system in and around Albuquerque. Currently (2000), the City of Albuquerque and surrounding municipalities are completely dependent on ground-water reserves for their municipal water supply. This report presents the results of a long-term aquifer test conducted near the Rio Grande in Albuquerque. The long-term aquifer test was conducted during the winter of 1994-95. The City of Albuquerque Griegos 1 water production well was pumped continuously for 54 days at an average pumping rate of 2,331 gallons per minute. During the 54-day pumping and a 30-day recovery period, water levels were recorded in a monitoring network that consisted of 3 production wells and 19 piezometers located at nine sites. These wells and piezometers were screened in river alluvium and (or) the upper and middle parts of the Santa Fe Group aquifer system. In addition to the measurement of water levels, aquifer-system compaction was monitored during the aquifer test by an extensometer. Well-bore video and flowmeter surveys were conducted in the Griegos 1 water production well at the end of the recovery period to identify the location of primary water- producing zones along the screened interval. Analytical results from the aquifer test presented in this report are based on the methods used to analyze a leaky confined aquifer system and were performed using the computer software package AQTESOLV. Estimated transmissivities for the Griegos 1 and 4 water production wells ranged from 10,570 to 24,810 feet squared per day; the storage coefficient for the Griegos 4 well was 0.0025. A transmissivity of 13,540 feet squared per day and a storage coefficient of 0.0011 were estimated from the data collected from a piezometer completed in the production interval of the Griegos 1 well.

    Despite widespread documentation of racial/ethnic disparities in care (predominantly under-use of needed care), differences in population-wide attitudes or experiences about under- or overuse (care where harms may outweigh potential benefits) of care are not well understood. We examined whether race/ethnicity is associated with perceptions or experiences of overuse or underuse. We conducted secondary analysis of a cross-sectional national telephone survey of nationally representative sample of 1238 American adults; 57.9 % female, 75.4 % Non-Hispanic White, 11.8 % Non-Hispanic Black, 10.1 % Hispanic. The main outcome measures are general perceptions and personal experiences of overuse and underuse, including cost-related dimensions of each. Bivariate results indicated that respondents of minority race/ethnicity generally viewed both overuse and underuse as bigger problems than did Whites, and reported more personal experiences of each. After adjustment, Hispanics were less likely than Whites to report personal experiences of overuse (odds ratio [OR] [95 % CI], 0.44 [0.23 to 0.86]), while Blacks and Others were more likely to report cost-related overuse (ORs [95 % CIs], 4.16 [2.30 to 7.51]; 3.55 [1.52 to 8.28], respectively). Non-Hispanic Others more often reported doctors' protection from overuse (OR [95 % CI], 3.69 [1.75 to 7.78]). General concerns with underuse were more frequent among Blacks and Hispanics (ORs [95 % CIs], 3.07 [1.72 to 5.54]; 2.12 [1.24 to 3.61] respectively), while Others reported significantly fewer concerns (OR [95 % CI], 0.43 [0.23 to 0.80]). Over- and underuse of medical care are important problems for many Americans, and experiences vary by race/ethnicity. Clinician communication and educational campaigns about appropriateness of care may need tailoring for varying population groups.

    This paper describes an innovative Pan-American survey on advanced-cancer care and examines the quality-of-care provided by Latin American institutions. A convenience sample of 777 physicians and nurses who treat cancer patients in Argentina, Brazil, Cuba, Mexico, and Peru were surveyed. Providers were identified through mass mailings, distribution at professional meetings and conferences, collaboration with regional institutions, professional organizations, and PAHO and online posting. Multiple linear regression analyses were conducted to identify predictors of quality-of-care assessments in each country. The five predictive models were subsequently compared descriptively. Higher access to care ratings and greater availability of end-of-life services corresponded with improved institutional quality-of-care ratings for all five countries. Barring respondents from Cuba, providers from the other four nations who practice in public institutions rated the quality of advanced-cancer care in their own institutions lower than those practicing in private hospitals or specialized cancer centers. Other institutional quality-of-care predictors included type of city, affordability-of-care ratings, availability of opioid analgesics, where patients die, barriers to cancer pain management, and the provider's specialty and gender. These findings highlight the need for providing accessible care and services to improve the quality of advanced-cancer care in Latin American institutions. Efforts should be aimed at improving the care offered in public institutions and addressing other types of disparities that may exist within countries by creating supportive and palliative cancer care programs that are accessible and affordable to those most in need.

    Objectives To examine whether the association between emotional support and indicators of health and quality of life differs between Canadian and Latin American older adults. Design Cross-sectional analysis of the International Mobility in Aging Study (IMIAS). Social support from friends, family members, children and partner was measured with a previously validated social network and support scale (IMIAS-SNSS). Low social support was defined as ranking in the lowest site-specific quartile. Prevalence ratios (PR) of good health, depression and good quality of life were estimated with Poisson regression models, adjusting for age, gender, education, income and disability in activities of daily living. Setting Kingston and Saint-Hyacinthe in Canada, Manizales in Colombia and Natal in Brazil. Participants 1600 community-dwelling adults aged 65–74 years, n=400 at each site. Outcome measures Likert scale question on self-rated health, Center for Epidemiological Studies Depression Scale and 10-point analogical quality-of-life (QoL) scale. Results Relationships between social support and study outcomes differed between Canadian and Latin American older adults. Among Canadians, those without a partner had a lower prevalence of good health (PR=0.90; 95% CI 0.82 to 0.98), and those with high support from friends had a higher prevalence of good health (PR=1.09; 95% CI 1.01 to 1.18). Among Latin Americans, depression was lower among those with high levels of support from family (PR=0.63; 95% CI 0.48 to 0.83), children (PR=0.60; 95% CI 0.45 to 0.80) and partner (PR=0.57; 95% CI 0.31 to 0.77); good QoL was associated with high levels of support from children (PR=1.54; 95% CI 1.20 to 1.99) and partner (PR=1.31; 95% CI 1.03 to 1.67). Conclusions Among older adults, different sources of support were relevant to health across societies. Support from friends and having a partner were related to good health in Canada, whereas in Latin America, support from family, children and

    Bacterial vaginosis (BV) is a common condition associated with serious complications including pelvic inflammatory disease (PID). However, the pathogenesis of BV is poorly understood. Toll-like receptors (TLR) are responsible for microbial recognition and elimination through inflammatory responses. TLR variants have been implicated in infectious and inflammatory diseases and may be involved in BV pathogenesis. We conducted a cross-sectional study to determine if TLR variants are associated with BV. Logistic regression was used to test associations between 14 variants assayed in 6 genes (TLR1, TLR2, TLR4, TLR6, TIRAP and MyD88) and BV/intermediate flora among 192 African-American women with clinical PID from the PID Evaluation and Clinical Health (PEACH) Study. Additionally, we examined associations between variants and endometrial BV-associated anaerobes. To account for multiple comparisons a permutated p<0.003 was used to determine statistical significance. African-American women with PID carrying the AA genotype for TLR2 SNP rs1898830 had a threefold increased rate of BV/intermediate flora (OR 2.9, 95% CI 1.2 to 7.3). This was not significant after accounting for multiple comparisons (p=0.0201). TLR2 variants rs1898830, rs11938228 and rs3804099 were associated with increased endometrial anaerobic gram-negative rods (p=0.0107, p=0.0076 p=0.0121), anaerobic non-pigmented Gram-negative rods (p=0.0231, p=0.0083, p=0.0044), and anaerobic Gram-positive cocci (p=0.0596, p=0.0640, p=0.1459). Among African-American women with PID, we observed trends between TLR2 variants, BV/intermediate flora, and BV-associated microbes. This provides some insight into BV pathogenesis. As not all BV-associated microbes may lead to pathology, future studies should focus on associations between TLR variants and individual BV-associated microbes.

    HIV prevalence is increasing among female sex workers (FSWs) in Mexico's Northern border region, who experience multiple occupational risks. Improving vulnerable populations' education, empowerment, and access to preventive services are important components of harm reduction strategies. Given the increasing interest in adapting harm reduction principles from drug use to sex work and other public health responses to the HIV epidemic, we used a sex work harm reduction framework to guide our investigation of FSWs' HIV knowledge. From 2004-2006, FSWs aged ≥18 years in Tijuana and Ciudad Juarez participated in a behavioral intervention study and completed structured interviews. Measures included HIV knowledge assessment and factors within each domain of our theoretical framework for sex work harms: (1) socio-demographic factors that may lead to sex work, (2) sex work characteristics and behaviors that may lead to harm, and (3) mutually reinforcing harms that lead to sex work and result from it (e.g., drug abuse). Negative binomial regression identified factors independently associated with suboptimal HIV knowledge (i.e., incorrect responses during the HIV knowledge assessment). Among 924 FSWs, the median proportion of incorrect responses was nearly one third (28% incorrect). Examination of item responses revealed misconceptions regarding specific transmission and prevention mechanisms, including prevention of mother to child transmission. Suboptimal HIV knowledge was independently associated with older age, lower education, living in Tijuana (vs. Ciudad Juarez), inconsistent condom use for vaginal sex with male clients, and lacking prior HIV testing. Our application of a sex work harm reduction framework to the study of FSWs' HIV knowledge is an important first step in enhancing HIV prevention efforts in Northern Mexican border cities. Our findings imply that interventions should identify and discredit local HIV misconceptions to improve knowledge of specific HIV

    Study Design Descriptive study. Background Professional meetings, such as the American Physical Therapy Association's (APTA's) Combined Sections Meeting (CSM), provide forums for sharing information. However, it was reported that only one-quarter of orthopaedic and sports physical therapy abstracts presented at the CSM between 2000 and 2004 went on to full-text publication. This low conversion rate raises a number of concerns regarding the full dissemination of work within the profession. Objectives The purpose of this study was to determine the full-text publication rate of work presented in abstract form at subsequent CSMs and investigate factors influencing the rate. Methods A systematic search was undertaken to locate full-text publications of orthopaedic and sports physical therapy abstracts presented at CSMs between 2005 and 2011. Eligible publications were published within 5 years following abstract presentation. The influences of year of abstract presentation, APTA section, presentation type, institution of origin, study design, and study significance were assessed. Results Over one-third (38.6%) of presented abstracts progressed to full-text publication. Odds of full-text publication increased if the abstract was presented as a platform presentation, originated from a doctorate-granting institution, reported findings of an experimental study, or reported a statistically significant finding. Conclusion The full-text publication rate for orthopaedic and sports physical therapy abstracts presented at recent CSMs has increased by over 50% compared to that reported for the preceding period. The rate is now in the range of that reported in comparable clinical disciplines, demonstrating important progress in the full dissemination of work within the profession.

    In late 1993, 562 questionnaires were sent to members of the Emergency Medicine Section of the American Academy of Pediatrics; of the questionnaires sent, 65% (365) were returned. Data were collected on 280 full-time practicing pediatric emergency physicians (PEPs). Eighty-two percent of these full-time PEPs have been practicing pediatric emergency medicine for less than 10 years, and two thirds of them are males. The majority work in pediatric emergency departments, devoting 28.1 clinical hours per week to their specialty. Ninety-nine percent of these full-time PEPs are board certified in pediatrics, and 61.5% are board certified in pediatric emergency medicine, whereas less than one quarter are fellowship trained. Approximately two thirds of these physicians feel that board certification in pediatric emergency medicine is a prerequisite for practicing; only one quarter feel that a fellowship in pediatric emergency medicine is required at this time. Average annual gross income for full-time PEPs was $111,000 per year; 62.8% of these physicians make more than $100,000 per year. PEPs indicated that diversity of their clinical practice and the medical acuity of their patients were the most desirable aspects of pediatric emergency medicine, whereas scheduling and the shift work nature of the profession, along with lack of follow-up in hospital practice, were seen as the least desirable aspects of the subspecialty.

    Little is known about the epidemiology of contact dermatitis (CD) in print machine operators (PMOs). The aims of this study were to estimate the prevalence of CD and characterize clinically relevant and occupationally related allergens among PMOs undergoing patch testing. This was a retrospective cross-sectional analysis of the North American Contact Dermatitis Group data from 1998 to 2014. Of 39,332 patch-tested patients, 132 (0.3%) were PMOs. Among PMOs, most were male (75.0%) and white (92.4%). The majority were printing press operators (85.6%). The most frequent sites of dermatitis were hands (63.6%), arms (29.5%), and face/scalp (24.2%). More than half had an occupationally related skin condition (56.1%). Final diagnoses were most commonly allergic CD (58.3%) and irritant CD (33.3%). Cobalt (20.8%), carba mix (12.5%), thiuram mix (8.3%), and formaldehyde (8.3%) were the most frequent occupationally related allergens. The top allergen sources included inks (22.9%), gloves (20.8%), and coatings/dye/copy/photographic chemicals (14.6%). Allergic CD, irritant CD, and involvement of exposed body areas were common among PMOs. Common allergens included rubber accelerators, metals, and preservatives.

    To describe current patterns of use of nerve blocks and trigger point injections for treatment of pediatric headache. Peripheral nerve blocks are often used to treat headaches in adults and children, but the available studies and practice data from adult headache specialists have shown wide variability in diagnostic indications, sites injected, and medication(s) used. The purpose of this study was to describe current practice patterns in the use of nerve blocks and trigger point injections for pediatric headache disorders. A survey was created in REDCap, and sent via email to the 82 members of the Pediatric and Adolescent Section of the American Headache Society in June 2015. The survey queried about current practice and use of nerve blocks, as well as respondents' opinions regarding gaps in the evidence for use of nerve blocks in this patient population. Forty-one complete, five incomplete, and three duplicate responses were submitted (response rate complete 50%). About 78% of the respondents identified their primary specialty as Child Neurology, and 51% were certified in headache medicine. Twenty-six (63%) respondents perform nerve blocks themselves, and seven (17%) refer patients to another provider for nerve blocks. Chronic migraine with status migrainosus was the most common indication for nerve blocks (82%), though occipital neuralgia (79%), status migrainosus (73%), chronic migraine without flare (70%), post-traumatic headache (70%), and new daily persistent headache (67%) were also common indications. The most commonly selected clinically meaningful response for status migrainosus was ≥50% reduction in severity, while for chronic migraine this was a ≥50% decrease in frequency at 4 weeks. Respondents inject the following locations: 100% inject the greater occipital nerve, 69% lesser occipital nerve, 50% supraorbital, 46% trigger point injections, 42% auriculotemporal, and 34% supratrochlear. All respondents used local anesthetic, while 12 (46%) also use

    Purpose This study aimed to determine the prevalence and severity of recurrent wheezing (RW) defined as ≥3 episodes of wheezing, risk factors, and treatments prescribed during the first year of life in Latin American infants. Methods In this international, cross-sectional, and community-based study, parents of 12,405 infants from 11 centers in 6 South American countries (Argentina, Brazil, Chile, Colombia, Peru, and Uruguay) completed a questionnaire about wheezing and associated risk/protective factors, asthma medications, and the frequency of and indications for the prescription of antibiotics and paracetamol during the first year of life. Results The prevalence of RW was 16.6% (95% CI 16.0-17.3); of the 12,405 infants, 72.7% (95% CI 70.7-74.6) visited the Emergency Department for wheezing, and 29.7% (27.7-31.7) was admitted. Regarding treatment, 49.1% of RW infants received inhaled corticosteroids, 55.7% oral corticosteroids, 26.3% antileukotrienes, 22.9% antibiotics ≥4 times mainly for common colds, wheezing, and pharyngitis, and 57.5% paracetamol ≥4 times. Tobacco smoking during pregnancy, household income per month <1,000 USD, history of parental asthma, male gender, and nursery school attendance were significant risk factors for higher prevalence and severity of RW, whereas breast-feeding for at least 3 months was a significant protective factor. Pneumonia and admissions for pneumonia were significantly higher in infants with RW as compared to the whole sample (3.5-fold and 3.7-fold, respectively). Conclusions RW affects 1.6 out of 10 infants during the first year of life, with a high prevalence of severe episodes, frequent visits to the Emergency Department, and frequent admissions for wheezing. Besides the elevated prescription of asthma medications, there is an excessive use of antibiotics and paracetamol in infants with RW and also in the whole sample, which is mainly related to common colds.

    We report a genome-wide association study of type 2 diabetes in an admixed sample from Mexico City and describe the results of a meta-analysis of this study and another genome-wide scan in a Mexican-American sample from Starr County, TX, USA. The top signals observed in this meta-analysis were followed up in the Diabetes Genetics Replication and Meta-analysis Consortium (DIAGRAM) and DIAGRAM+ datasets. We analysed 967 cases and 343 normoglycaemic controls. The samples were genotyped with the Affymetrix Genome-wide Human SNP array 5.0. Associations of genotyped and imputed markers with type 2 diabetes were tested using a missing data likelihood score test. A fixed-effects meta-analysis including 1,804 cases and 780 normoglycaemic controls was carried out by weighting the effect estimates by their inverse variances. In the meta-analysis of the two Hispanic studies, markers showing suggestive associations (p < 10(-5)) were identified in two known diabetes genes, HNF1A and KCNQ1, as well as in several additional regions. Meta-analysis of the two Hispanic studies and the recent DIAGRAM+ dataset identified genome-wide significant signals (p < 5 × 10(-8)) within or near the genes HNF1A and CDKN2A/CDKN2B, as well as suggestive associations in three additional regions, IGF2BP2, KCNQ1 and the previously unreported C14orf70. We observed numerous regions with suggestive associations with type 2 diabetes. Some of these signals correspond to regions described in previous studies. However, many of these regions could not be replicated in the DIAGRAM datasets. It is critical to carry out additional studies in Hispanic and American Indian populations, which have a high prevalence of type 2 diabetes.

    Clay mineralogy and geochemical studies were carried out on sandstone and shale samples collected from the Sierra San José section of the Morita Formation to infer the paleoclimate and paleoweathering conditions that prevailed in the source region during the deposition of these sediments. The clay mineral assemblages (fraction < 2 μm) of the Sierra San José section are composed of chlorite and illite. The abundance of illite and chlorite in the studied samples suggest that the physical weathering conditions were dominant over chemical weathering. Additionally, the illite and chlorite assemblages reflect arid or semi-arid climatic conditions in the source regions. K2O/Al2O3 ratio of shales vary between 0.15 and 0.26, which lie in the range of values for clay minerals, particularly illite composition. Likewise, sandstones vary between 0.06 and 0.13, suggesting that the clay minerals are mostly kaolinte and illite types. On the chondrite-normalized diagrams, sandstone and shale samples show enriched light rare earth elements (LREE), flat heavy rare earth elements (HREE) patterns and negative Eu anomalies. The CIA and PIA values and A-CN-K plot of shales indicate low to moderate degree of weathering in the source regions. However, the sandstones have moderate to high values of CIA and PIA suggesting a moderate to intense weathering in the source regions. The SiO2/Al2O3 ratios, bivariate and ternary plots, discriminant function diagram and elemental ratios indicate the felsic source rocks for sandstone and shale of the Morita Formation.

    In the present work, we studied the genetic diversity of Mycobacterium tuberculosis clinical isolates from patients according to their gender, age, and geographic location in Mexico. We did not observe any statistically significant differences in regard to age or gender. We found that spoligo international type 53 (SIT53) is more frequent in the northern states and that SIT119 predominates in central Mexico. Copyright © 2014, American Society for Microbiology.

  6. The Upper- to Middle-Crustal Section of the Alisitos Oceanic Arc, (Baja, Mexico): an Analog of the Izu-Bonin-Marianas (IBM) Arc

    The Rosario segment of the Cretaceous Alisitos arc in Baja California is an outstanding field analog for the Izu-Bonin-Mariana (IBM) arc, because it is structurally intact, unmetamorphosed, and has superior three-dimensional exposures of an upper- to middle-crustal section through an extensional oceanic arc. Previous work1, done in the pre-digital era, used geologic mapping to define two phases of arc evolution, with normal faulting in both phases: (1) extensional oceanic arc, with silicic calderas, and (2) oceanic arc rifting, with widespread diking and dominantly mafic effusions. Our new geochemical data match the extensional zone immediately behind the Izu arc front, and is different from the arc front and rear arc, consistent with geologic relations. Our study is developing a 3D oceanic arc crustal model, with geologic maps draped on Google Earth images, and GPS-located outcrop information linked to new geochemical, geochronological and petrographic data, with the goal of detailing the relationships between plutonic, hypabyssal, and volcanic rocks. This model will be used by scientists as a reference model for past (IBM-1, 2, 3) and proposed IBM (IBM-4) drilling activities. New single-crystal zircon analysis by TIMS supports the interpretation, based on batch SIMS analysis of chemically-abraded zircon1, that the entire upper-middle crustal section accumulated in about 1.5 Myr. Like the IBM, volcanic zircons are very sparse, but zircon chemistry on the plutonic rocks shows trace element compositions that overlap to those measured in IBM volcanic zircons by A. Schmitt (unpublished data). Zircons have U-Pb ages up to 20 Myr older than the eruptive age, suggesting remelting of older parts of the arc, similar to that proposed for IBM (using different evidence). Like IBM, some very old zircons are also present, indicating the presence of old crustal fragments, or sediments derived from them, in the basement. However, our geochemical data show that the magmas are

    Both iron deficiency and iron deficiency anemia are common in the United States with a prevalence amongst women of 12 % and 4 % respectively. These numbers are even higher in African-American women (AAW) and are often a result of heavy menstrual bleeding (HMB). The primary objective of this study was to determine if perceived assessment of menstrual bleeding was associated with objective and subjective measures of anemia in AAW. Quantitative cross-sectional pilot study with surveys and venipuncture. 44 premenopausal AAW (mean age 37.9 years ± 9. 4) participated in the study. Iron deficiency was present in 68.2 % of the participants and 18.2 % were anemic. Almost half of the participants reported that their menses were heavy or very heavy, and there was a relationship between perceived heaviness of menstrual flow and anemia (P = 0.021). Of the individuals who reported that their menses were heavy or very heavy, 35.0 % were anemic. AAW who reported heavy or very heavy menses had significantly lower hemoglobin (P = 0.015), hematocrit (P = 0.003), and ferritin (P = 0.012) levels, as well as more general (P = 0.006) and menses-associated symptoms of anemia (P = 0.015) than those who reported normal or light menses. This pilot study of premenopausal AAW found that a significant percentage of women who report HMB are not only iron deficient, but also anemic. AAW should be educated on the consequences of HMB and counseled to seek care with a women's health provider when they perceive HMB. More importantly, providers should be aware that when AAW report HMB, evaluation for iron deficiency and anemia are essential.

    Background: Eating breakfast is believed to promote a healthy body weight. Yet, few studies have examined the contribution of energy balance–related behavioral factors to this relation in minority youth. Objective: We assessed the associations between breakfast consumption and dietary intake, physical activity (PA), and adiposity before and after accounting for energy intake and PA in minority girls. Design: Cross-sectional data were obtained on body mass index (BMI), percentage body fat (measured by BodPod), dietary intake (measured with 3-d dietary records), and PA (measured with 7-d accelerometry) from 87 Latina and African American girls 8–17 y of age (75% Latina, 80% overweight). Dietary records were used to categorize girls as more frequent breakfast eaters (MF; 2 or 3 of 3 d; n = 57) or less frequent breakfast eaters (LF; 0 or 1 of 3 d; n = 30). Chi-square tests, ANCOVA, and multiple regression analyses were conducted. Mediation was assessed with a Sobel test. Results: Compared with the MF group, the LF group spent 30% less time (12.6 min/d) in moderate-to-vigorous-intensity PA (MVPA; P = 0.004) and had a higher percentage body fat (P = 0.029). MVPA accounted for 25% (95% CI: −8.8%, 58.1%; P = 0.139) of the relation between breakfast consumption and percentage body fat. We were unable to show that energy intake or MVPA was a significant mediator of the relation between breakfast consumption and adiposity in this sample. Conclusions: Evidence suggests that among predominantly overweight minority girls, MVPA, but not energy intake, was associated with both breakfast consumption and adiposity; however, a lack of power reduced our ability to detect a significant mediation effect. Other unobserved variables likely contribute to this relation. PMID:23803890

    The opinions of the pediatric orthopaedic workforce are shaped by market forces, regulatory processes, and local experience. The purpose of this report is to summarize the findings of the recent Workforce Survey of the American Academy of Pediatrics (AAP) Section on Orthopaedics (SOOr). This submission has been reviewed and approved by the Board of Directors of the Pediatric Orthopaedic Society of North America (POSNA). In 2014, the AAP generated a survey to assess perceptions of pediatric orthopaedic surgeons about current issues that affect practice. The survey was sent to 856 POSNA and 141 AAP-SOOr members. Responses were topically organized to report current workforce composition, practice patterns, and perceptions about electronic medical records (EMRs). Responses were collected from August to December, 2014, from 496 (50%) survey recipients including 83 of 141 (59%) AAP-SOOr members and 413 of 856 (48%) POSNA members. Analyses were restricted to the 397 respondents who reported that they are currently practicing pediatric orthopaedics. Nearly all of these (390/391, 100%) indicated that they provide direct patient care and work an average of 60 hours per week. Many (105/378, 28%) indicated that they would soon limit their practice or retire. A majority (299/394, 76%) indicated that they face competition in their geographic area, predominantly due to pediatric orthopaedic subspecialists (269/299, 90%). Major business changes had recently occurred or were anticipated by 21% of participants. Respondents reported that use of EMR makes them less efficient (252/397, 63%) and interferes with the patient-physician relationship (172/397, 43%). This workforce survey suggests that pediatric orthopaedic surgeons are concerned with challenges of competition despite concurrent increasing volume and complexity of referrals. External processes such as EMR changes are perceived to negatively impact practice efficiency and satisfaction.

  10. Prevalence of overweight and obesity, and dieting attitudes among Caucasian and African American college students in Eastern North carolina: A cross-sectional survey

    2010-01-01

    A cross-sectional survey was used to investigate the rates of overweight and obesity (BMI ≥ 25), and eating attitudes among college students. Data were collected at a large southeastern university. Adolescents (ages 18-25) self-reported weight and height (to calculate BMI), and, in addition to demographic information, completed the eating attitudes (EAT 26) scale to assess dieting tendencies. Significance of the mean BMI differences between gender and ethnic background were assessed by one-way analysis of variance (one-way ANOVA). Chi-square was used to determine whether the rate of those with BMI≥25 between gender and ethnic background was statistically significant. While 52.7% of the students' BMI were within the normal weight category, 15.2% were underweight, 21.3% were overweight, and 10.8% were obese. The rate of BMI≥25 differed by gender and ethnicity, with males and African Americans having higher rates. About 12 % of the participants reported disturbed eating behavior, which is lower than previously reported. Even so, results support the generally held belief that disturbed eating attitudes and unhealthy dieting are common among college students, especially among females. At the same time, disturbed eating attitudes are not just the domain of young female students; about 10% of college males reported disturbed eating attitudes. Findings of this study call for obesity prevention/intervention and lifestyle modification outreach programs among college students. Weight status and unhealthy eating behaviors of college students should be a concern to health care professionals. While obese young adults will likely remain obese throughout their adult life, excessive dieting among students, which is linked to eating disorders and other health hazards, does not provide healthy and adequate alternatives for maintaining a normal BMI. Implications for obesity prevention programs are discussed. PMID:20198207

    Home to about 15 million people, the US-Mexico border area has suffered stresses from increased border security efforts and a costly drug war in Mexico. Whether immigration patterns add to increasing levels of anxiety for the Mexican population and the Mexican-origin individuals living in the US-Mexico border and near the border is unknown. We used the US-Mexico Study on Alcohol and Related Conditions (UMSARC), a cross-sectional survey (2011-2013) of individuals living in border and non-border cities of the US (n = 2336) and Mexico (n = 2460). In Mexico respondents were asked if they ever migrated to the US or have a family member living in the US (328) or not (2124), while in the US respondents were asked if they were born in Mexico (697), born in the US with no US-born parents (second generation, 702) or born in the US with at least one US-born parent (third generation, 932). The prevalence and risk factors for symptoms of anxiety using the Beck Anxiety Inventory (>=10) were obtained. Mexicans with no migrant experience had a prevalence of anxiety and adjusted prevalence ratio (PR) within the last month of 6.7% (PR = reference), followed by Mexicans with migration experience of 13.1% (PR = 1.8), Mexican-born respondents living in the US of 17.3% (PR = 2.6), US born Mexican-Americans of 2nd generation of 18.6% (PR = 3.3) and finally US born 3rd + generation of 25.9% (PR = 3.8). Results help to identify regions and migration patterns at high risk for anxiety and may help to unravel causal mechanisms that underlie this risk. Copyright © 2014 Elsevier Ltd.

    Although the relationship between health behaviors and outcomes such as smoking and obesity with longer residence in the United States among Mexican American immigrants is established, the relationship between length of residency in the United States and risk for cardiovascular disease (CVD) is not fully understood. The objective of this study was to determine the relationship between immigrant status, length of residence in the United States, age, and CVD markers in a sample of Mexican American adults living in Brownsville, Texas. We categorized participants in the Cameron County Hispanic Cohort study as immigrants in the United States for 10 years or less, immigrants in the United States for more than 10 years, or born in the United States. We conducted logistic and ordinary least squares regression for self-reported chronic conditions and CVD biomarkers. We found bivariate differences in the prevalence of self-reported conditions and 1 CVD biomarker (low-density lipoprotein cholesterol) by length of residence in the middle (41-64 y) and younger (18-40 y) age groups. After adjusting for covariates, the following varied significantly by immigrant status: stroke and high cholesterol (self-reported conditions) and diastolic blood pressure, systolic blood pressure, total cholesterol, and low-density lipoprotein cholesterol (CVD biomarkers). The association between immigrant status, length of residence in the United States, and CVD markers varied. The effect of length of residence in the United States or immigrant status may depend on age and may be most influential in middle or older age.

    The Rosario Formation forms part of the Peninsular Ranges forearc basin complex, which crops out discontinuously along the Pacific coast of the Baja California Peninsula, Mexico. This study concerns the upper, deep marine part of the Rosario Formation , which includes several slope channel systems, one of these, the San Fernando channel systems consists of five channel complex sets (CCS1 to CCS5), each characterized by three filling stages. Stage I consists of predominantly clast­ and matrix-supported conglomerates, with subordinate medium to coarse grained sandstones. Stage II consists of units of clast-supported conglomerates with subordinate medium to coarse-grained sandstones, separated by mainly thinly-bedded turbidites (intercalation of thin beds of fine-grained sandstones and mudstones). Stage III consists mainly of hemipelagic mudstones. The main objective of this research is to determine source area and to compare the coarse fraction and finer fraction (fragments <2 cm) from conglomerates of each channel set, combining provenance methodology such as heavy minerals, clast counting, geochemistry, bulk petrography and U/Pb in detrital zircons by LA-ICPMS and SHRIMP. The heavy minerals assembly identified were Ca amphibole, epidote, clinozoisite, titanite, garnet, tourmaline, apatite, rutile and zircon, among them amphiboles are by far the most abundant detrital mineral. Clast counting and petrographic characterization showed that the pebble fraction of the conglomerates is constituted at least 18 different, and the majority being composed by pyroclastic, porphyritic volcanic and sandstone rocks. Bulk quantification indicates that the main provenance tectonic mode of the fine fraction of the conglomerates can be interpreted as dissected magmatic arc, with subordinate uplifted basement and recycled orogenic contributions. The preliminary conclusion is that the sedimentary supply to the Rosario Formation was mostly derived from volcanic and plutonic rocks of

    The Hillsboro and San Lorenzo 15-minute quadrangles of southwestern New Mexico have been mapped at a 1:48,000 scale and selected mineralized areas within these quadrangles have been mapped in greater detail. This area of about 550 mi2 (1,424 km2) is within the southern part of the Black Range and includes much of the Mimbres Mountains and parts of the adjoining Black Range Primitive area. The region is highly mineralized with Laramide (75.1 ? 2.5 m.y.) and middle Tertiary (about 32 to 35 m.y.) intrusions providing the source for much of the base- and precious-metal mineralization. The porphyry copper deposit at Copper Flat is a subvolcanic Laramide quartz monzonite stock that was intruded into a thick section (>2,700 ft or >823 m) of Upper Cretaceous andesite. Numerous gold-bearing veins radiate from the central quartz monzonite stock, and locally offset a radial system of quartz latite dikes. Gold-bearing veins, chiefly along the south and east periphery of the stock, have provided the source for both gold lode and placer deposits. The middle Tertiary rhyolitic plugs, stocks, and dikes have intruded a dominantly carbonate section of Paleozoic sediments and bedding replacement deposits of zinc, lead, and copper are closely associated with tactite in the Carpenter (Swartz) mining district. The rich oxidized silver deposits of the Kingston district are largely fault controlled and a metallizing pluton is not present at the surface outcrop. Some of the silver-bearing base-metal veins in the Kingston district contain rhodochrosite, rhodonite, and alabandite and the highly oxidized parts of these veins have been mined for manganese ore. Very minor amounts of tungsten, as scheelite, occur in thin tactite zones along Tank Canyon, at the Silver Queen claims near Kingston, and at the Silver Tail group of mines along Pierce Canyon.

    Mexico, located in one of the world's most seismically active regions, lies on three large tectonic plates: the North American plate, Pacific plate, and Cocos plate. The relative motion of these tectonic plates causes frequent earthquakes and active volcanism and mountain building. Mexico's most seismically active region is in southern Mexico where the Cocos plate is subducting northwestward beneath Mexico creating the deep Middle America trench. The Gulf of California, which extends from approximately the northern terminus of the Middle America trench to the U.S.-Mexico border, overlies the plate boundary between the Pacific and North American plates where the Pacific plate is moving northwestward relative to the North American plate. This region of transform faulting is the southern extension of the well-known San Andreas Fault system.

  15. Biological pest control in Mexico.

    PubMed

    Williams, Trevor; Arredondo-Bernal, Hugo C; Rodríguez-del-Bosque, Luis A

    2013-01-01

    Mexico is a megadiverse country that forms part of the Mesoamerican biological corridor that connects North and South America. Mexico's biogeographical situation places it at risk from invasive exotic insect pests that enter from the United States, Central America, or the Caribbean. In this review we analyze the factors that contributed to some highly successful past programs involving classical biological control and/or the sterile insect technique (SIT). The present situation is then examined with reference to biological control, including SIT programs, targeted at seven major pests, with varying degrees of success. Finally, we analyze the current threats facing Mexico's agriculture industry from invasive pests that have recently entered the country or are about to do so. We conclude that despite a number of shortcomings, Mexico is better set to develop biological control-based pest control programs, particularly on an area-wide basis, than many other Latin American countries are. Classical and augmentative biological control and SIT-based programs are likely to provide effective and sustainable options for control of native and exotic pests, particularly when integrated into technology packages that meet farmers' needs across the great diversity of production systems in Mexico.

    Histopathologic features of New Mexico 2009 H1N1 fatalities have not been representative of those reported nationwide. We retrospectively reviewed medical records of all New Mexico 2009 pandemic influenza A (pH1N1) fatalities (n = 50). In cases in which autopsy was performed (n = 12), histologic sections and culture results were examined. In contrast to previously published studies, the majority of our fatalities did not have diffuse alveolar damage (DAD) (2/12; 16.7%). Common findings included pulmonary interstitial inflammation and edema, tracheobronchitis, and pneumonia. Two cases had significant extra-pulmonary manifestations: myocarditis and cerebral edema with herniation. The majority had a rapid disease course: range from 1 to 12 days (median, 2 days), and Native Americans were disproportionately represented among fatalities. These findings suggest that New Mexico H1N1 fatalities generally did not survive long enough to develop the classic picture of DAD. Pathologists should be aware that H1N1 may cause extra-pulmonary pathology and perform postmortem cultures and histologic sampling accordingly.

    Background. Researchers have emphasized a need to identify predictors that can explain the variability in weight management after bariatric surgery. Eating self-efficacy has demonstrated predictive impact on patients’ adherence to recommended eating habits following multidisciplinary treatment programs, but has to a limited extent been subject for research after bariatric surgery. Recently an American short form version (WEL-SF) of the commonly used Weight Efficacy Lifestyle Questionnaire (WEL) was available for research and clinical purposes. Objectives. We intended to translate and culturally adapt the WEL-SF to Norwegian conditions, and to evaluate the new versions’ psychometrical properties in a Norwegian population of morbidly obese patients eligible for bariatric surgery. Design. Cross-sectional Methods. A total of 225 outpatients selected for Laparoscopic sleeve gastrectomy (LSG) were recruited; 114 non-operated and 111 operated patients, respectively. The questionnaire was translated through forward and backward procedures. Structural properties were assessed performing principal component analysis (PCA), correlation and regression analysis were conducted to evaluate convergent validity and sensitivity, respectively. Data was assessed by mean, median, item response, missing values, floor- and ceiling effect, Cronbach’s alpha and alpha if item deleted. Results. The PCA resulted in one factor with eigenvalue > 1, explaining 63.0% of the variability. The WEL-SF sum scores were positively correlated with the Self-efficacy and quality of life instruments (p < 0.001). The WEL-SF was associated with body mass index (BMI) (p < 0.001) and changes in BMI (p = 0.026). A very high item response was obtained with only one missing value (0.4%). The ceiling effect was in average 0.9 and 17.1% in the non-operated and operated sample, respectively. Strong internal consistency (r = 0.92) was obtained, and Cronbach’s alpha remained high (0.86–0.92) if single items

    Circulating 25-hydroxyvitamin D [25(OH)D] concentration is inversely associated with peripheral arterial disease and hypertension. Vascular remodeling may play a role in this association, however, data relating vitamin D level to specific remodeling biomarkers among ESRD patients is sparse. We tested whether 25(OH)D concentration is associated with markers of vascular remodeling and inflammation in African American ESRD patients. We conducted a cross-sectional study among ESRD patients receiving maintenance hemodialysis within Emory University-affiliated outpatient hemodialysis units. Demographic, clinical and dialysis treatment data were collected via direct patient interview and review of patients records at the time of enrollment, and each patient gave blood samples. Associations between 25(OH)D and biomarker concentrations were estimated in univariate analyses using Pearson's correlation coefficients and in multivariate analyses using linear regression models. 25(OH) D concentration was entered in multivariate linear regression models as a continuous variable and binary variable (<15 ng/ml and ≥15 ng/ml). Adjusted estimate concentrations of biomarkers were compared between 25(OH) D groups using analysis of variance (ANOVA). Finally, results were stratified by vascular access type. Among 91 patients, mean (standard deviation) 25(OH)D concentration was 18.8 (9.6) ng/ml, and was low (<15 ng/ml) in 43% of patients. In univariate analyses, low 25(OH) D was associated with lower serum calcium, higher serum phosphorus, and higher LDL concentrations. 25(OH) D concentration was inversely correlated with MMP-9 concentration (r = -0.29, p = 0.004). In multivariate analyses, MMP-9 concentration remained negatively associated with 25(OH) D concentration (P = 0.03) and anti-inflammatory IL-10 concentration positively correlated with 25(OH) D concentration (P = 0.04). Plasma MMP-9 and circulating 25(OH) D concentrations are significantly and inversely associated among ESRD

    We recently reported that Japanese had higher liver fat at a lower level of BMI compared with non-Hispanic whites (NHW). We hypothesize that ethnic difference in fat storage capacity contributes to this ethnic difference in liver fat. To examine this, we assessed liver fat among 244 Japanese-American aged 40-49, using regional computed-tomography images, along with metabolic variables. Despite the similar BMI between Japanese-Americans and NHW men, Japanese-Americans had more liver fat (liver to spleen attenuation ratio: 1.03 ± 0.22 for Japanese-Americans, and 1.07 ± 0.15 for NHW men; p < 0.05) and tended to have a greater disposition for fatty liver with an increase in BMI than NHW, indicating a clear difference between the two groups. In addition, liver fat is less in Japanese-Americans compared with Japanese men (1.03 ± 0.22 vs. 1.01 ± 0.16; p < 0.05), despite of a much higher BMI. These ethnic differences support the hypothesis that higher fat storage capacity indeed seems to be associated with less liver fat. In all the groups, liver fat content strongly correlated with triglycerides, homeostasis model assessment-insulin resistance, and C-reactive protein (CRP). Nevertheless, these metabolic variables were worse in Japanese-Americans, despite of less liver fat, compared with Japanese. Moreover, CRP levels were least among Japanese with highest liver fat, and highest among NHW men with least liver fat, despite of a strong positive association between CRP and fatty liver within each population. Fat content in the liver is intermediate for Japanese-Americans compared with Japanese and NHW men, which supports the hypothesis of less fat storage capacity among Japanese, closely linked to ethnic difference in predisposition to fatty liver. © 2011 Asian Oceanian Association for the Study of Obesity.

Design To examine this, we assessed liver fat among 244 Japanese-American aged 40-49, using regional computed-tomography images, along with metabolic variables. Results Despite the similar BMI between Japanese-Americans and NHW men, Japanese-Americans had more liver fat (liver to spleen attenuation ratio: 1.03 ± 0.22 for Japanese-Americans, and 1.07 ± 0.15 for NHW men; p<0.05) and tended to have a greater disposition for fatty liver with an increase in BMI than NHW, indicating a clear difference between the two groups. In addition, liver fat is less in Japanese-Americans compared with Japanese men (1.03 ± 0.22 vs. 1.01 ± 0.16; p<0.05), despite of a much higher BMI. These ethnic differences support the hypothesis that higher fat storage capacity indeed seems to be associated with less liver fat. In all the groups, liver fat content strongly correlated with triglycerides, homeostasis model assessment-insulin resistance, and C-reactive protein (CRP). Nevertheless, these metabolic variables were worse in Japanese-Americans, despite of less liver fat, compared with Japanese. Moreover, CRP levels were least among Japanese with highest liver fat, and highest among NHW men with least liver fat, despite of a strong positive association between CRP and fatty liver within each population. Conclusions Fat content in the liver is intermediate for Japanese-Americans compared with Japanese and NHW men, which supports the hypothesis of less fat storage capacity among Japanese, closely linked to ethnic difference in predisposition to fatty liver.

    This report examines selected factor affecting Mexico's future petroleum policies, and then assesses various implications of Mexico's petroleum for US interests and policies. After a brief introduction, the report is divided into three sections. The first offers a detailed analysis of Mexico's petroleum resources and production possibilities. The second considers petroleum as a symbolic issue of profound significance for Mexican nationalism. The final section provides an assessment of these and other factors for US interests, objectives, and policy options during the 1980s.

  16. Interferometric synthetic aperture radar observation of vertical land displacement in the vicinity of the All-American Canal at the United States and Mexico border

    Han, Joo-Yup

    Interferometric Synthetic Aperture Radar (InSAR) provided a synoptic view of the status of groundwater levels in the vicinity of the All-American Canal (AAC) by measuring vertical land displacements. The European Remote Sensing satellite SAR images were used to produce surface deformation maps. The full time period (1992-2000) was divided to two shorter periods (early and late) (1992-97 and 1996-2000). For low coherence areas such as agricultural fields in the Mexicali Valley, Persistent Scatterers InSAR (PSInSAR) was used to detect any deformation signals. The surface deformation maps from InSAR indicated that there were insignificant vertical land displacements in the vicinity of the AAC. However, the surrounding areas of the East Mesa Geothermal Field (EMGF) were subsiding over the full observation period (-38 mm/year). The maximum subsidence rate at the EMGF was reduced by 21% between the early (-43 mm/year) and late (-34 mm/year) periods. The AAC was within the edges of the spatial extent of the EMGF subsidence, especially during the early period, which was associated with a high averaged net geothermal production. The maximum subsidence on the East Highline Canal was -9.5 +/- 0.5 cm and -2.4 +/- 0.8 cm for the early and late periods, respectively. Results from PSInSAR in Mexicali City and the Mexicali Valley showed insignificant displacements. This lack of deformation indicated that there was no measurable surface deformation in the areas, but validation data were not available. The most interesting phenomenon is the high density of persistent scatterers in the areas between the Andrade Mesa and the Mexicali Valley, and the Sand Hills dunes. Forward modeling was conducted to characterize the reservoir zone of the EMGF based on the InSAR displacement over the full time period. Inputs to the model were the maximum subsidence (-3.8 cm) and depth of the reservoir, the radius of the reservoir and Poisson's ratio. An interactive approach was conducted to find the

    The abundance of total and pathogenic Vibrio parahaemolyticus (Vp) strains in American oysters (Crassostrea virginica) harvested in two different harvest sites from the Mandinga lagoon System was evaluated monthly for 1 year (January through December 2012). Frequencies of species-specific genes and pathogenic genes exhibited a seasonal distribution. The annual occurrence of Vp with the species-specific tlh gene (tlh(+)) was significantly higher during the winter windy season (32.50%) and spring dry season (15.0%), with the highest densities observed during spring dry season at 283.50 most probable number (MPN)/g (lagoon bank A, near human settlements), indicating the highest risk of infection during warmer months. Pathogenic Vp tlh(+)/tdh(+) frequency was significantly higher during the winter windy and the spring dry seasons at 22.50 and 10.00%, respectively, with highest densities of 16.22 and 41.05 MPN/g (bank A), respectively. The tlh/trh and tdh/trh gene combinations were also found in Vp isolates during the spring dry season at 1.25 and 1.3%, respectively, with densities of 1.79 and 0.4 MPN/g (bank A), respectively. The orf8 genes were detected during the winter windy season (1.25%) with highest densities of 5.96 MPN/g (bank A) and 3.21 MPN/g (bank B, near mangrove islands and a heron nesting area). Densities of Vp tdh(+) were correlated (R(2) = 0.245, P < 0.015) with those of Vp orf8(+). The seasonal dynamics of Vp harboring pathogenic genes varied with seasonal changes, with very high proportions of Vp tdh(+) and Vp orf8(+) isolates in the winter windy season at 46.2 and 17.0%, respectively, which suggests that environmental factors may differentially affect the abundance of pathogenic subpopulations. Although all densities of total Vp (Vp tlh(+)) were lower than 10(4) MPN/g, thus complying with Mexican regulations, the presence of pathogenic strains is a public health concern. Our results suggest that total Vp densities may not be appropriate for assessing

    The High Altitude Water Cerenkov detector HAWC will be a powefull instrument to survey the TeV sky. Mexico has proposed to locate this experiment in the Parque Nacional Pico de Orizaba, between Citlaltepetl and Tliltepetl, host of the Large Millimeter Telescope (LMT). The region has a sizeable technical infrastructure related to the LMT and we recently studied a 4100m location in terms of its feasibility to host HAWC. We present the proposed site location and extension, its water acquisition, experimental and complementary infrastructures.
