    In Mexico, the nongovernmental organization Sevisio, Desarrollo y Paz, A.C. (SEDEPAC) is helping poor women acquire legal knowledge in an economic climate characterized by the increased feminization of poverty brought about by the Structural Adjustment Program. The Mexican legal system is grounded in a patriarchal tradition, and the codified laws continue to favor men. Women were not granted full citizenship until 1953, and discrimination against women was not addressed in Mexican law until 1974 as the country prepared to host the First UN International Women's Conference. However, legal advances are not being applied in the family or in larger society where men remain in power. Mexico also distinguishes between private law and public law. Because domestic violence falls in the realm of private law, authorities are loathe to follow-up on women's complaints in this area. Since its founding in 1983, SEDEPAC has applied a gender perspective to its activities and programs. SEDEPAC held its first women's legal workshop in 1987 and realized that most poor women have no knowledge of existing laws or their rights, that alternative legal services for women are scarce, that existing laws must be changed, and that the authoritarian and conservative legal system helps maintain cultural stereotypes. Since then, SEDEPAC has held annual workshops, follow-up meetings, and training sessions and has provided counseling. The main topics addressed are women's social conditions; violence and the penal code; civil rights, power, and dependency; women's bodies and reproductive rights; and women's organization and leadership. The workshops use techniques of popular education such as group participation and use of gossip as a communication tool. The workshops have changed participants' lives and led to the formation of an independent Popular Defenders' Coordination.

    Research examining how cultural factors affect adjustment of ethnic minority individuals would be strengthened if study samples better represented the diversity within these populations. To recruit a representative sample of Mexican American families, the authors implemented a multiple-step process that included sampling communities to represent diversity in cultural and economic conditions, recruiting participants through schools, using culturally attractive recruitment processes, conducting interviews in participants' homes, and providing a financial incentive. The result was a sample of 750 families that were diverse in cultural orientation, social class, and type of residential communities and were similar to the census description of this population. Thus, using culturally appropriate adaptations to common recruitment strategies makes it possible to recruit representative samples of Mexican Americans.

    Objective: To establish distribution frequency and demographic characteristics of salivary gland tumours (SGT) i6n order to identify possible risk profiles. Design of study: The present report constitutes an eight year retrospective study (January 2000-August 2007). The archives of the Clinical and Experimental Pathology Laboratory (Graduate and Research Division, Dental School, National Autonomous University of Mexico) as well as archives of the Surgical Pathology Service (General Hospital, Mexico City) were subject to revision in order to select all cases where SGT tumour diagnoses were emitted. Age and gender of patients as well as SGT topography were obtained from medical records. Selected cases were classified according to location of the lesion, histological lineage and biological behaviour. Results: 360 cases of SGT were included, 227 (67%) cases were benign tumours, while 83 cases (23%) were malignant tumours. SGT were most frequent in women with ages ranging from their 3rd to 5th decades of life. 275 tumours were located in major salivary glands, 78.9% of them were identified in the parotid gland. The most frequent location of tumours arising from minor salivary glands (33 cases, 38%) was found in the palatine glands. Tumours of epithelial lineage were the predominant histological type. The most frequent benign tumours were pleomorphic adenomas (86.1%) and papillary cystadenoma lymphomatosum (7.3%). The most frequent malignant tumours were adenoid cystic carcinomas (25%) and mucoepidermoid carcinomas (23.6%) Conclusions: Salivary gland tumours in Mexican population appear principally in major salivary glands of women in their 3rd to 5th decade of life. Key words: Salivary glands tumours, epithelial tumours, pleomorphic adenoma, papillary cistadenoma lymphomatosum, adenoid cystic carcinoma, mucoepidermoid carcinoma. PMID:22143697

    OBJECTIVE: The study was designed to evaluate the association between socioeconomic level (as measured by maternal education, maternal occupation, and monthly family income) and anencephaly. METHODS: The authors conducted a case-control study using data from the Epidemiological Surveillance System Register for Neural Tube Defects for three states of the Mexican Republic: Puebla, Guerrero and the State of Mexico. Mothers of 151 cases of infants born with anencephaly and mothers of 151 control infants born during the period March 2000 to February 2001 were interviewed about their socioeconomic characteristics and other factors including reproductive history, use of prenatal care, use of tobacco and alcohol, fever during pregnancy, and folic acid supplementation. RESULTS: After adjustment for potential confounders, a risk gradient was seen with decreasing maternal education. Women with less than a primary school education (adjusted odds ratio [OR]=3.0; 95% confidence interval [CI] 1.2, 7.6) and women who had completed primary school but had not completed junior high school (adjusted OR=2.2; 95% CI 0.9, 5.7) had higher risks of giving birth to an infant with anencephaly, compared to women with a higher educational level. A monthly income < or = 1,000 pesos (approximately dollars 100 U.S.) was also associated with a higher risk of anencephaly (OR=2.5; 95% CI 1.2, 5.1). Women employed in industry or agriculture during the acute risk period (three months prior to conception to one month after conception) had a risk 6.5 times (95% CI 1.4, 29.6) that of professional and business women. CONCLUSIONS: This study helps to identify groups that may be especially vulnerable to this type of congenital malformation so that primary and secondary preventive strategies can be targeted to these groups.

    Background Physical performance tests play a major role in the geriatric assessment. In particular, gait speed has shown to be useful for predicting adverse outcomes. However, risk factors for slow gait speed (slowness) are not clearly described. Objectives To determine risk factors associated with slowness in Mexican older adults. Design A two-step process was adopted for exploring the antecedent risk factors of slow gait speed. First, the cut-off values for gait speed were determined in a representative sample of Mexican older adults. Then, antecedent risk factors of slow gait speed (defined using the identified cut-points) were explored in a nested, cohort case-control study. Setting, participants One representative sample of a cross-sectional survey for the first step and the Mexican Health and Aging Study (a cohort characterized by a 10-year follow-up). Measurements A 4-meter usual gait speed test was conducted. Lowest gender and height-stratified groups were considered as defining slow gait speed. Sociodemographic characteristics, comorbidities, psychological and health-care related variables were explored to find those associated with the subsequent development of slow gait speed. Unadjusted and adjusted logistic regression models were performed. Results In the final model, age, diabetes, hypertension, and history of fractures were associated with the development of slow gait speed. Conclusions Early identification of subjects at risk of developing slow gait speed may halt the path to disability due to the robust association of this physical performance test with functional decline.

    Purpose Understanding how the convergence between chronic and complex diseases—such as cancer—and emerging conditions of older adults—such as frailty—takes place would help in halting the path that leads to disability in this age group. The objective of this manuscript is to describe the association between a past medical history of cancer and frailty in Mexican older adults. Methods This is a nested in cohort case-control study of the Mexican Health and Aging Study. Frailty was categorized by developing a 55-item frailty index that was also used to define cases in two ways: incident frailty (incident >0.25 frailty index score) and worsening frailty (negative residuals from a regression between 2001 and 2012 frailty index scores). Exposition was defined as self-report of cancer between 2001 and 2012. Older adults with a cancer history were further divided into recently diagnosed (<10 years) and remotely diagnosed (>10 years from the initial diagnosis). Odds ratios were estimated by fitting a logistic regression adjusted for confounding variables. Results Out of a total of 8022 older adults with a mean age of 70.6 years, the prevalence of a past medical history of cancer was 3.6 % (n = 288). Among these participants, 45.1 % had been diagnosed with cancer more than 10 years previously. A higher risk of incident frailty compared to controls [odds ratio (OR) 1.53 (95 % confidence interval (CI) 1.04–2.26, p = 0.03); adjusted model OR 1.74 (95 % CI 1.15–2.61, p = 0.008)] was found in the group with a recent cancer diagnosis. Also, an inverse association between a remote cancer diagnosis and worsening frailty was found [OR = 0.56 (95 % CI 0.39–0.8), p = 0.002; adjusted model OR 0.61 (95 % CI 0.38–0.99, p = 0.046)]. Conclusions Cancer is associated with a higher frailty index, with a potential relevant role of the time that has elapsed since the cancer diagnosis. Implications for cancer survivors Cancer survivors may be more likely to develop frailty or

    The objective of this study was to quantify and assess whether lifting tasks in the workplace are a risk factor in lumbar spondyloarthrosis etiology. A case-control study was performed with 231 workers, 18-55 years old, insured by the Mexican Social Security Institute (IMSS, according to its designation in Spanish). A multivariate analysis using conditional logistical regression showed that lifting tasks, combined with driving tasks, are associated with this illness (OR = 7.3; 95% CI 1.7-31.4). The daily frequency of lifting as it interacts with work as a driver resulted in a greater risk (OR = 10.4; 95% CI 2.0-52.5). The load weight, daily task-hours and cumulative time showed a dose-response relationship. The attributable risk for lifting tasks was 0.83, suggesting that 83% of lumbar spondyloarthrosis development could be prevented if risk factors were eliminated by ergonomic redesign of the task.

    The Kansas Statewide Farmworker Health Program (KSFHP) has developed a unique set of culturally competent health interventions in response to the pressing public health needs of the state's underserved farmworker population. Key among these are its health education and translation efforts on behalf of the fast-growing Low German-speaking Mexican Mennonite farmworker population. Linguistic, religious, and cultural values have created unique and complex health disparities and barriers to care that can be broken down only through innovative approaches. KSFHP first conducted a health needs assessment survey of the farmworker population in 2003, which indicated prenatal care practices as a significant health disparity, especially among the Low German-speaking Mexican Mennonite population. In response, KSFHP successfully lobbied the state health department to implement a new standard of health behavior data collection that includes primary language data as a method of delineating population subgroups, making Kansas one of the first two states in the country to collect this information. KSFHP also developed culturally competent Low German-language recordings on health topics such as prenatal care in accordance with the information delivery needs of the Low German-speaking Mexican Mennonite farmworker population. Currently, a pilot program is in progress that offers additional outreach, health education, and interpretation, among other services. The work of the KSFHP has significant implications for further research into health disparities, specialized minority populations, and culturally competent data collection methods.

    We present a single-centre, retrospective study (1985-2012) of 22 cases of mucormycosis in children. A total of 158 mucormycosis cases were identified, of which 22 (13.96%) were children. The mean age of the children was 10.3 years (range: 6 months-18 years), and 59% of the infections occurred in males. The rhinocerebral form was the main clinical presentation (77.27%), followed by the primary cutaneous and pulmonary patterns. The major underlying predisposing factors were diabetes mellitus in 68.18% of the patients and haematologic diseases in 27.7% of the patients. The cases were diagnosed by mycological tests, with positive cultures in 95.4% of the patients. Rhizopus arrhizus was the foremost aetiologic agent in 13/22 cases (59.1%). In 21 cultures, the aetiologic agents were identified morphologically and by molecular identification. In 10 cultures, the internal transcribed spacer region of the ribosomal DNA was sequenced. Clinical cure and mycological cure were achieved in 27.3% cases, which were managed with amphotericin B deoxycholate and by treatment of the underlying conditions.

  18. A case study of the effects of social experiences on the science identity formation of Mexican American females in high school chemistry

    Beeton, Renee P.

    Mexican Americans are a rapidly growing ethnic group in the United States. However, they are noticeably absent from physical science fields. Little research has explored the experiences of Mexican American girls in high school chemistry. The theories of identity based on communities of practice and multicultural feminism framed this year-long case study of nine Mexican American girls in a high school chemistry course. This study explored the social encounters and experiences that shaped the participants' identities and how their views of themselves affected their attitudes towards high school chemistry and future science careers. Data collection included a focus group and in-depth interviews with the participants, classroom observations, and teacher interviews. Five main identities influenced the participants' potential to become a scientist: ethnic, gender, science, student, and college. Mexican ethnic identity was the overarching identity; however gender also influenced the participants' other identities. The participants were aware of ethnic gender stereotypes that might hinder them from being successful in science. Also, ethnic factors, such as citizenship and abilities to receive financial aid limited their views of themselves as chemists. Participatory science, student, and school identities were all needed in order for the participants to be potential scientists. Family expectations, authentic relationships with teachers, and personal connections were important factors in the development of these participatory identities.

    This is a case study of Celeste, postulant in a Roman Catholic convent in Mexico who experienced frequent episodes of leaving her body to commune with God. During these experiences, Celeste felt immersed in an ;incredibly beautiful profound silence' where ;time and space were broken.' But as much as Celeste craved these experiences, they also alarmed her; she was acutely aware that they might be indicative of psychological or neurological dysfunction. This article chronicles Celeste's struggles to make sense of her experiences in light of competing explanatory models. Her ultimate resolution suggests intriguing new directions for transcultural psychiatric research.

The authors used a qualitative interpretative approach with life histories, interviewing eight female users of healthcare services in California and seven key informants in Mexico and California. There were three main types of barriers to healthcare: immigration status, language, and gender. Participants reported long waiting times, discriminatory attitudes, and high cost of services. A combination of formal and informal healthcare services was common. The assessment of quality of care was closely related to undocumented immigration status. Social support networks are crucial to help solve healthcare issues. Quality of care should take intercultural health issues into account. PMID:23703003

    Objective. There is a lack of information about the genotype frequencies of IL-6 −174G/C and −572G/C polymorphisms in Mexicans with rheumatoid arthritis (RA). Therefore, the aim of this study was to evaluate the association of the IL-6 −174G/C and −572G/C polymorphisms in Mexican mestizo with RA. Methods. We included 137 patients with RA and 102 healthy controls. Patients were assessed for clinical characteristics. IL-6 −174G/C and −572G/C polymorphisms were genotyped using PCR-RFLP analysis. Allele and genotype frequencies and the Hardy-Weinberg equilibrium were computed. Odds ratios (ORs) were computed to identify the risk for RA associated with the presence of GG genotype in comparison with the GC or CC genotypes. Results. The genotype −174GG occurred at a higher frequency in cases and controls (77.4% versus 78.4%, P = 0.845). We found similar results for the genotype −572GG (54% in patients versus 60.8% in controls, P = 0.295). Conclusions. This is the first study to evaluate the association of −174G/C and −572G/C polymorphisms of the IL-6 gene with RA in Mexican mestizo patients. These two polymorphisms were not associated with RA in the studied sample. Additional studies are required to evaluate if these IL-6 polymorphisms have relevance to the development of more severe disease. PMID:24223608

    There is a dearth of literature examining how adversity shapes the experiences of pain and/or suffering in a middle aged Mexican American women. The purpose of this qualitative descriptive study was to understand pain and suffering from a life course perspective as described by a Mexican American woman aging with early onset mobility impairment. This Hispanic woman experienced episodes of abuse and rejection over the life course, which may have significantly influenced her pain and suffering experience in adulthood. This adds to the literature on how adversity influences later life pain experience and provides insight on why pharmacological treatment alone may not be as successful as a holistic intervention. Hay escasez de literatura que examine cómo la adversidad da forma a las experiencias de dolor y / o sufrimiento en mujeres mexicana-americana mayores de edad. El propósito de este estudio descriptivo cualitativo fue comprender el dolor y el sufrimiento desde una perspectiva de ciclo de vida como descrito por una mujer mexicana-americana envejeciendo con inicio temprano de deterioro de movilidad. Esta Latina experimentó episodios de maltrato y rechazo, que se percibió haber afectado su experiencia de dolor y sufrimiento luego como adulta. Este estudio aumenta la literatura sobre cómo la adversidad influya la experiencia de dolor más tarde en la vida, y nos permite comprender mejor como el tratamiento farmacológico por sí solo no es tan exitoso como pueda ser una intervención integral.

    Background: The C-reactive protein (CRP) and the tumor necrosis factor-alpha (TNF-α) are considered markers of inflammation and have been shown to predict the risk of incident cardiovascular events. However, few studies have undertaken a comprehensive examination of SNPs (single nucleotide polymorphisms) of the CRP and TNF-α genes; due to this, we will present a protocol study to evaluate the role of the CRP and TNF-α genes in Mexican individuals. Methods/design: we will perform a case-control study to explore the CRP and TNF-α genotype distribution as well as the serum influence of rs1800947, rs1130864, rs2794521 and rs1205 (polymorphisms of the CRP gene) and rs361525, rs1800629, rs1799724, rs1800630, rs1799964 (of the TNF-α gene) in Mexican individuals who present coronary artery disease. Ethics and dissemination: a written informed consent will be obtained from all the participating subjects. An article detailing the results of the study will be submitted for publication in an international peer-reviewed journal, in accordance with STROBE criteria. PMID:26751459

    Background An estimated 800,000 people worldwide are occupationally exposed to welding-fumes. Previous studies show that the exposure to such fumes is associated with damage to genetic material and increased cancer risk. In this study, we evaluate the genotoxic effect of welding-fumes using the Micronucleus Test on oral mucosa cells of Mexican welders. Material and Methods We conducted a cross-sectional, matched case-control study of n = 66 (33 exposed welders, and 33 healthy controls). Buccal mucosa smears were collected and stained with acridine orange, observed under 100x optical amplification with a fluorescence lamp, and a single-blinded observer counted the number of micronuclei and other nuclear abnormalities per 2,000 observed cells. We compared the frequencies of micronuclei and other nuclear abnormalities, and fitted generalised linear models to investigate the interactions between nuclear abnormalities and the exposure to welding-fumes, while controlling for smoking and age. Results Binucleated cells and condensed-chromatin cells showed statistically significant differences between cases and controls. The frequency of micronuclei and the rest of nuclear abnormalities (lobed-nuclei, pyknosis, karyolysis, and karyorrhexis) did not differ significantly between the groups. After adjusting for smoking, the regression results showed that the occurrence of binucleated cells could be predicted by the exposure to welding-fumes plus the presence of tobacco consumption; for the condensed-chromatin cells, our model showed that the exposure to welding-fumes is the only reliable predictor. Conclusions Our findings suggest that Mexican welders who are occupationally exposed to welding-fumes have increased counts of binucleated and condensed-chromatin cells. Nevertheless, the frequencies of micronuclei and the rest of nuclear abnormalities did not differ between cases and controls. Further studies should shed more light on this subject. PMID:26244938

    Background Although the etiology of preeclampsia is still unclear, recent work suggests that changes in circulating angiogenic factors play a key role in its pathogenesis. In the trophoblast of women with preeclampsia, hypoxia-inducible factor 1 alpha (HIF-1α) is over-expressed, and induces the expression of non-angiogenic factors and inhibitors of trophoblast differentiation. This observation prompted the study of HIF-1α and its relation to preeclampsia. It has been described that the C1772T (P582S) and G1790A (A588T) polymorphisms of the HIF1A gene have significantly greater transcriptional activity, correlated with an increased expression of their proteins, than the wild-type sequence. In this work, we studied whether either or both HIF1A variants contribute to preeclampsia susceptibility. Results Genomic DNA was isolated from 150 preeclamptic and 105 healthy pregnant women. Exon 12 of the HIF1A gene was amplified by PCR, and the genotypes of HIF1A were determined by DNA sequencing. In preeclamptic women and controls, the frequencies of the T allele for C1772T were 4.3 vs. 4.8%, and the frequencies of the A allele for G1790A were 0.0 vs. 0.5%, respectively. No significant differences were found between groups. Conclusion The frequency of the C1772T and G1790A polymorphisms of the HIF1A gene is very low, and neither polymorphism is associated with the development of preeclampsia in the Mexican population.

  10. High resolution human leukocyte antigen (HLA) class I and class II allele typing in Mexican mestizo women with sporadic breast cancer: case-control study

    2009-01-01

    Background The development of breast cancer is multifactorial. Hormonal, environmental factors and genetic predisposition, among others, could interact in the presentation of breast carcinoma. Human leukocyte antigen (HLA) alleles play an important role in immunity (cellular immunity) and may be important genetic traits. HLAAllele-specific interaction has not been well established. Recently, several studies had been conducted in order to do so, but the results are controversial and in some instances contradictory. Methods We designed a case-control study to quantify the association of HLA class I and II genes and breast cancer. HLA typing was performed by high resolution sequence-specific oligotyping after DNA amplification (PCR-SSOP) of 100 breast cancer Mexican mestizo patients and 99 matched healthy controls. Results HLA-A frequencies that we were able to observe that there was no difference between both groups from the statistical viewpoint. HLA-B*1501 was found three times more common in the case group (OR, 3.714; p = 0.031). HLA-Cw is not a marker neither for risk, nor protection for the disease, because we did not find significant statistical differences between the two groups. DRB1*1301, which is expressed in seven cases and in only one control, observing an risk increase of up to seven times and DRB1*1602, which behaves similarly in being present solely in the cases (OR, 16.701; 95% CI, 0.947 – 294.670). DQ*0301-allele expression, which is much more common in the control group and could be protective for the presentation of the disease (OR, 0.078; 95% CI, 0.027–0.223, p = 0.00001). Conclusion Our results reveal the role of the MHC genes in the pathophysiology of breast cancer, suggesting that in the development of breast cancer exists a disorder of immune regulation. The triggering factor seems to be restricted to certain ethnic groups and certain geographical regions since the relevant MHC alleles are highly diverse. This is the first study in Mexican

    Because the Mexican government has encouraged investment in Mexico by increasing the percentage of ownership of a Mexican business that a US company can hold, joint ventures are more attractive now than they had been in the past. This study provides preliminary information for US renewable energy companies who are interested in forming a joint venture with a Mexican company. This report is not intended to be a complete reference but does identifies a number of important factors that should be observed when forming a Mexican joint venture: (1)Successful joint ventures achieve the goals of each partner. (2)It is essential that all parties agree to the allocation of responsibilities. (3)Put everything in writing. (4)Research in depth the country or countries in which you are considering doing business.

  12. Application of the positive matrix factorization approach to identify heavy metal sources in sediments. A case study on the Mexican Pacific Coast.

    During the last two decades, sediments collected in different sources of water bodies of the Tehuantepec Basin, located in the southeast of the Mexican Pacific Coast, showed that concentrations of heavy metals may pose a risk to the environment and human health. The extractable organic matter, geoaccumulation index, and enrichment factors were quantified for arsenic, cadmium, copper, chromium, nickel, lead, vanadium, zinc, and the fine-grained sediment fraction. The non-parametric SiZer method was applied to assess the statistical significance of the reconstructed metal variation along time. This inference method appears to be particularly natural and well suited to temperature and other environmental reconstructions. In this approach, a collection of smooth of the reconstructed metal concentrations is considered simultaneously, and inferences about the significance of the metal trends can be made with respect to time. Hence, the database represents a consolidated set of available and validated water and sediment data of an urban industrialized area, which is very useful as case study site. The positive matrix factorization approach was used in identification and source apportionment of the anthropogenic heavy metals in the sediments. Regionally, metals and organic matter are depleted relative to crustal abundance in a range of 45-55 %, while there is an inorganic enrichment from lithogenous/anthropogenic sources of around 40 %. Only extractable organic matter, Pb, As, and Cd can be related with non-crustal sources, suggesting that additional input cannot be explained by local runoff or erosion processes.

    2015-01-01

    We use a data set of Mexican researchers working abroad that are included in the Mexican National System of Researchers (SNI). Our diaspora sample includes 479 researchers, most of them holding postdoctoral positions in mainly seven countries: USA, Great Britain, Germany, France, Spain, Canada and Brazil. Their research output and impact is explored in order to determine their patterns of production, mobility and scientific collaboration as compared with previous studies of the SNI researchers in the periods 1991–2001 and 2003–2009. Our findings confirm that mobility has a strong impact on their international scientific collaboration. We found no substantial influence among the researchers that got their PhD degrees abroad from those trained in Mexican universities. There are significant differences among the areas of knowledge studied: biological sciences, physics and engineering have better production and impact rates than mathematics, geosciences, medicine, agrosciences, chemistry, social sciences and humanities. We found a slight gender difference in research production but Mexican female scientists are underrepresented in our diaspora sample. These findings would have policy implications for the recently established program that will open new academic positions for young Mexican scientists. PMID:26047501

    Background The epidemiology of Helicobacter pylori infection in inmates has not been previously studied. Therefore, we determine the seroepidemiology of H. pylori infection in inmates. Methods Through a case-control study, inmates from a state correctional facility in Durango, Mexico and subjects without incarceration of the same city were examined for the presence of anti-H. pylori IgG antibodies using enzyme-linked immunoassays. Seroprevalence association with socio-demographic, incarceration, clinical and behavioral characteristics of the inmates was also investigated. Results Antibodies to H. pylori were found in 140 (83.3%) of 168 inmates and in 101 (60.1%) of 168 controls. Seroprevalence of anti-H. pylori IgG antibodies was significantly higher in inmates than in controls (OR = 3.32; 95% CI: 1.93 - 5.71; P = 0.000002). The seroprevalence of H. pylori infection was not influenced by gender, age, or socioeconomic status of inmates. Seropositivity to H. pylori was found in 3 of 3 inmates with peptic ulcer and in 1 of 2 inmates with gastritis. The seroprevalence of H. pylori exposure was high regardless the jail section, duration (years) in incarceration and number of incarcerations. Multivariate analysis revealed that H. pylori exposure was positively associated with having tattoos (OR = 3.34; 95% CI: 1.14 - 9.70; P = 0.02), and negatively associated with drug abuse (OR = 0.28; 95% CI: 0.11 - 0.70; P = 0.007). Conclusions Seroprevalence of H. pylori exposure in inmates is higher than those found in non-incarcerated people and other populations in the region. Results indicate that inmates may represent a new risk group for H. pylori exposure. Results warrant for further research on the potential role of incarceration and behavioral features of inmates for H. pylori infection.

    2013-10-01

    The current study investigated the role of cultural values in the resilience of Mexican American college students. Utilizing mixed methodology, 124 self-identified Mexican American college students were asked to complete an online survey, including a demographic questionnaire, the Resilience Scale, Mexican American Cultural Values Scale, and 2 open-ended questions concerning overcoming adversity and cultural values. As hypothesized, Mexican American traditional cultural values (Familismo, Respeto, Religiosidad, and Traditional Gender Roles) predicted resilience, with Familismo accounting for the majority of the variance. Consensual qualitative research (Hill, Thompson, & Nutt Williams, 1997) was used to identify emergent domains and themes within the open-ended question responses. Traditional Mexican American Value themes included Familismo, Ethnic Identity, Religiosidad, Perseverance, and Respeto. Results highlight the important role that certain Mexican American cultural values play in providing strength for overcoming adversities.

    2007-05-01

    Persistent aura symptoms in patients with migraine are rare but well documented. The International Headache Society defines persistent aura without infarction as when the aura symptoms persist for > 1 week without radiographic evidence of infarction. The visual aura of migraine attacks has been explained by cortical spreading depression. We describe a case of a 28-year-old Mexican woman, who presented with persistent aura symptoms, and a literature review. The patient had a 24-year history of migraine headache. In November 2005 the patient had an attack which started with scintillating scotomas bilaterally associated with photopsias and amaurosis followed by migraine headache. All imaging studies were negative. The episode lasted 35 days and probably resolved with nimodipine therapy. Persistent aura symptoms are rare entities. This is the first case documented of a Mexican patient with persistent aura without infarction and probably resolved with nimodipine therapy.

    In this case-control study we determined whether dietary differences underlie some of the ethnic and sex differences in US lung cancer rates. We examined the relationship between diet and lung cancer development in 137 lung cancer cases (93 African Americans and 44 Mexican Americans) and 187 controls (78 African Americans and 109 Mexican Americans). Cases reported a higher daily mean total fat intake (p < 0.001), whereas controls had a higher daily mean intake of dietary fiber (p < 0.001) and fruits (p = 0.02). Ethnic differences in diet were also observed: Mexican Americans consumed less total fat (p < 0.02) and more fiber (p < 0.001) and vegetables (p = 0.08) than African Americans. Additionally, men consumed more total fat (p = 0.08) and less fiber (p = 0.001), fruits (p < 0.001), and vegetables (p = 0.002) than women. Multivariable analysis, after adjustment for the effects of pack-years of smoking, age, total energy intake, sex, and ethnicity, demonstrated a positive association between high total fat consumption and lung cancer risk (p < 0.01) and an inverse association between high fruit consumption and lung cancer risk (p = 0.05). In conclusion, our findings support the hypothesis that diet, particularly high fat consumption and low fruit and vegetable consumption, contributes (independent of cigarette smoking) to the excess lung cancer risk in African-American men, who have the highest lung cancer rates in the United States.

    Ehlers-Danlos syndrome (EDS) is a heterogeneous group of heritable connective tissue disorders whose primary clinical features include soft and extensible skin, articular hypermobility and tissue fragility. EDS type VIIC or ‘human dermatosparaxis’ is an autosomal recessive disease characterized by severe skin fragility and sagging redundant skin (major criteria) with a soft, doughy texture, easy bruising, premature rupture of fetal membranes and large hernias (minor criteria). Dermatosparaxis (meaning ‘tearing of skin’), which has been described in several non-human species, is a disorder of the connective tissue resulting from a deficiency of the enzyme that cleaves the registration peptide off the N-terminal end of collagen after it has been secreted from fibroblasts. We describe a Mexican case from consanguineous parents with all the phenotypical characteristics previously described, plus skeletal abnormalities. PMID:22787447

    2013-01-01

    Among oncohematological diseases, acute lymphoid leukemia (ALL) and acute myeloid leukemia (AML) are characterized by the uncontrolled production and accumulation of blasts that can lead to death. Although the physiopathology of these diseases is multifactorial, a genetic factor seems to be at play. Several studies worldwide have shown association of ALL and AML with several alleles of the major histocompatibility complex (MHC). Objective. To determine gene frequencies of HLA-B alleles in Mexicans (individuals with Native American genetic background admixed with European descent) with ALL and AML. Methods. We compared the HLA-B alleles in 213 patients with ALL and 85 patients with AML to those present in 731 umbilical cord blood (UCB) samples as a control group; this was done by means of the PCR-SSP technique. Results. We found an increased frequency of the HLA-B*40 allele in ALL patients as compared to the control group (14.5% versus 9.84%, P = 0.003, OR = 1.67); this was particularly evident in a subgroup of young (less than 18 years old) ALL patients (P = 0.002, OR = 1.76); likewise, a decreased frequency of HLA-B*40 allele in AML patients was observed as compared to the control group (4.70% versus 9.84%, P = 0.02, OR = 0.42). Conclusions. These results might suggest opposing effects of the HLA-B*40 in the genetic susceptibility to develop ALL or AML and offer the possibility to study further the molecular mechanisms of cell differentiation within the bone marrow lineage.

    Salivary gland tumours are an important part of the Oral and Maxillofacial Pathology, unfortunately, only few studies on these tumours have been done in Latin-American population. The aim of this study was to compare demographic data on salivary gland tumours in a Mexican sample with those previously published from Latin American and non-Latin American countries. All cases of salivary gland tumours or lesions diagnosed in our service were reviewed. Of the reviewed cases,67 were confirmed as salivary gland tumours. Out of these 64.2% were benign neoplasms, 35.8% were malignant and a slight female predominance (56.7%) was found. The most common location was palate followed by lips and floor of the mouth. Mean age for benign tumours was 40.6 years with female predominance (60.5%). Mean age for malignant tumours was 41 years and female predominance was found again. Palate followed by retromolar area were the usual locations. Pleomorphic adenoma (58.2%), mucoepidermoid carcinoma (17.9%) and adenoid cystic carcinoma (11.9%) were the more frequent neoplasms. All retromolar cases were malignant and all submandibular gland tumours were benign. We found a high proportion of salivary gland neoplasms in children. Our results showed that differences of the studied tumours among our sample and previously reported series exist. These differences can be related to race and geographical location.

    Background Studies of the nursing work environment are increasingly common in developed countries, but few exist in developing countries. Because of resource differences between the two contexts, researchers need to clarify what aspects of the work environments are similar and different. Objectives To study the perspectives of Mexican nurses about their work environments to determine similarities and differences to results from developed world studies. Design A secondary, directed content analysis of qualitative data from 46 Spanish language interviews using workplace-oriented themes Setting Purposively selected Mexican states from four regions of the country that reflect the country’s socioeconomic differences. Participants Practicing Mexican nurses with at least one year of clinical experience and currently working in nursing. Participants were recruited through convenience and snowball sampling techniques. Methods Initial data collection occurred in 2006 and 2008 during a broader study about professionalization processes that occurred in Mexican nursing between 1980 and 2005. The secondary, directed content analysis focused on an in-depth exploration of a central theme that emerged from the two original studies: The Workplace. The directed content analysis used themes from the global nursing work environment literature to structure the analysis: Professional relationships, organizational administrative practices, and quality of care and services. Results The three themes from the global literature were relevant for the Mexican context and a new one emerged related to hiring practices. By category, the same factors that created positive or negative perceptions of the work environment matched findings from other international studies conducted in developed countries. The descriptors of the category, however, had different conceptual meanings that illustrate the health system challenges in Mexico. Conclusions Findings from this study suggest that studies that

    Background The aging population in Latin America is characterized by not optimal conditions for good health, experiencing high burden of comorbidity, which contribute to increase the frequency of frailty; thus, identification should be a priority, to classify patients at high risk to develop its negative consequences. Aim The objective of this analysis was to validate the FRAIL instrument to measure frailty in Mexican elderly population, from the database of the Mexican Health and Aging Study (MHAS). Materials and methods Prospective, population study in Mexico, that included subjects of 60 years and older who were evaluated for the variables of frailty during the year 2001 (first wave of the study). Frailty was measured with the five-item FRAIL scale (fatigue, resistance, ambulation, illnesses, and weight loss). The robust, pre-frail or intermediate, and the frail group were considered when they had zero, one, and at least two components, respectively. Mortality, hospitalizations, falls, and functional dependency were evaluated during 2003 (second wave of the study). Relative risk was calculated for each complications, as well as hazard ratio (for mortality) through Cox regression model and odds ratio with logistic regression (for the rest of the outcomes), adjusted for covariates. Results The state of frailty was independently associated with mortality, hospitalizations, functional dependency, and falls. The pre-frailty state was only independently associated with hospitalizations, functional dependency, and falls. Conclusions Frailty measured through the FRAIL scale, is associated with an increase in the rate of mortality, hospitalizations, dependency in activities of daily life, and falls. PMID:26646253

  15. Doctors and corporatist politics: the case of the Mexican medical profession.

    PubMed

    Nigenda, G; Solórzano, A

    1997-02-01

    This study advances our understanding of the relationship between the state and the medical profession in countries where health care services are used as instruments of economic and political control. As a general argument, we maintain that the corporatist nature of the Mexican state impedes the medical profession from achieving autonomy and control over its professional activities. In contraposition to medical professions in developed societies, the nature of the Mexican profession is shaped by state policies and by its reiterated efforts to act independently of the state's tutelage. We analyze this dynamic interaction through three different historical epochs that reflect the complexity and uniqueness of the Mexican medical profession. Whatever attempts the profession has made to control the medical curriculum, the licensing process, the market, or the specific laws that affect its own field, the Mexican state has responded with measures that systematically divide and antagonize the different factions of medical associations. The result is a highly fragmented and disenfranchised medical profession with dissimilar political, professional, personal, and academic aims. In the final analysis, the interests of the corporatist Mexican state prevail over the interests of the groups, including doctors. The evisceration of the medical corps by the Mexican state results in a profession with low salaries, higher rates of unemployment, atomization in terms of political representation, and heavily co-opted medical organizations that seem to neglect the overwhelming health care needs of the Mexican people.

    2016-10-01

    Research suggests that Mexican immigrants arrive in the United States with equivalent or better health than native-born whites but lose their advantage over time. We seek to examine systematically how well the patterns of initial advantage and deteriorating health apply to immigrants originating from other regions of the world - regions that represent a growing proportion of U.S. immigrants. We begin by identifying which of the groups in our study have a health advantage compared to U.S.-born whites and to Mexican immigrants. We then we assess changes in health over time, controlling for variation in the health profiles of cohorts upon arrival. We use logistic regression of self-rated health and heart conditions with data from the 2004-2013 National Health Interview Survey. The results reveal diversity and similarity in health outcomes across world regions of origin, both on arrival and over time. By comparing and contrasting cases previously examined in isolation, we clarify and qualify theories of the immigrant health paradox and health deterioration. PMID:27544464

  1. Coping with negative social identity: the case of Mexican immigrants.

    Shinnar, Rachel S

    2008-10-01

    Social identity theory suggests that an individual's self-concept is shaped through group identification and positive social identities are established by favorably comparing the individual's in-group against an out-group. When unfavorable intergroup comparisons occur, individuals perceive a negative social identity. Because of the motivation to maintain a positive self-concept, this perception creates a need to cope. On the basis of face-to-face interviews with Mexican immigrants, the author examined the ways in which negative social-identity perceptions triggered different coping mechanisms. The findings offer support for two coping mechanisms--individual mobility and social creativity, with social creativity used more often than individual mobility.

    Objective To describe the characteristics and prognosis of subjects classified as frail in a large sample of Mexican community-dwelling elderly. Materials and methods An eleven-year longitudinal study of 5 644 old adults participating in the Mexican Health and Aging Study (MHAS). Frailty was defined loss, weakness, exhaustion, slow walking speed and low physical activity. The main outcomes were incident disability and death. Multiple covariates were used to test the prognostic value of frailty. Results Thirty-seven percent of participants (n = 2 102) met the frailty criteria. Frail participants were significantly older, female, less disease, lower income, and poorer self-reported health status, in comparison with their non-frail counterparts. Frailty was a predictor both for disability activities of daily living and for mortality. Conclusion After a follow-up of more than ten years, the phenotype of frailty was a predictor for adverse health-related outcomes, including ADL disability and death. PMID:26172236

    Environmental assessment at the community level in highly diverse ecosystems is limited by taxonomic constraints and statistical methods requiring true replicates. Our objective was to show how diverse systems can be studied at the community level using higher taxa as biodiversity surrogates, and re-sampling methods to allow comparisons. To illustrate this we compared the abundance, richness, evenness and diversity of the litter fauna in a pine-oak forest in central Mexico among seasons, sites and collecting methods. We also assessed changes in the abundance of trophic guilds and evaluated the relationships between community parameters and litter attributes. With the direct search method we observed differences in the rate of taxa accumulation between sites. Bootstrap analysis showed that abundance varied significantly between seasons and sampling methods, but not between sites. In contrast, diversity and evenness were significantly higher at the managed than at the non-managed site. Tree regression models show that abundance varied mainly between seasons, whereas taxa richness was affected by litter attributes (composition and moisture content). The abundance of trophic guilds varied among methods and seasons, but overall we found that parasitoids, predators and detrivores decreased under management. Therefore, although our results suggest that management has positive effects on the richness and diversity of litter fauna, the analysis of trophic guilds revealed a contrasting story. Our results indicate that functional groups and re-sampling methods may be used as tools for describing community patterns in highly diverse systems. Also, the higher taxa surrogacy could be seen as a preliminary approach when it is not possible to identify the specimens at a low taxonomic level in a reasonable period of time and in a context of limited financial resources, but further studies are needed to test whether the results are specific to a system or whether they are general

    Background: Little is known about the epidemiology of suicide attempts among psychiatric outpatients in Mexico. This study was aimed to determine the socio-demographic, clinical and behavioral characteristics associated with suicide attempts in psychiatric outpatients in two public hospitals in Durango, Mexico. Methods: Two hundred seventy six psychiatric outpatients (154 suicide attempters and 122 patients without suicide attempt history) attended the two public hospitals in Durango City, Mexico were included in this study. Socio-demographic, clinical and behavioral characteristics were obtained retrospectively from all outpatients and compared in relation to the presence or absence of suicide attempt history. Results: Increased prevalence of suicide attempts was associated with mental and behavioral disorders due to psychoactive substance use (F10-19) (P=0.01), schizophrenia, schizotypal and delusional disorders (F20-29) (P=0.02), mood (affective) disorders (F30-39) (P<0.001), and disorders of adult personality and behavior (F60-69) (P<0.001). Multivariate analysis showed that suicide attempts were associated with young age (OR=1.21, 95% CI: 1.06-1.39; P=0.003), female gender (OR=2.98, 95% CI: 1.55-5.73; P=0.001), urban residence (OR=2.31, 95% CI: 1.17-4.57; P=0.01), memory impairment (OR=1.91, 95% CI: 1.07-3.40; P=0.02), alcohol consumption (OR=2.39, 95% CI: 1.21-4.70; P=0.01), and sexual promiscuity (OR=3.90, 95% CI: 1.74-8.77; P<0.001). Conclusions: We report the association of suicide attempts with socio-demographic, clinical and behavioral characteristics in psychiatric outpatients in Mexico. Results may be useful for an optimal planning of preventive measures against suicide attempts in psychiatric outpatients. PMID:24711751

    In recent years, glyphosate-tolerant legumes have been used as cover crops for weed management in tropical areas of Mexico. Mexican cologania (Cologania broussonetii (Balb.) DC.) is an innate glyphosate-tolerant legume with a potential as a cover crop in temperate areas of the country. In this work, glyphosate tolerance was characterized in two Mexican cologania (a treated (T) and an untreated (UT)) populations as being representatives of the species, compared in turn to a glyphosate-susceptible hairy fleabane (S) (Conyza bonariensis (L.) Cronq.) population. Experiments revealed that T and UT Mexican cologania populations had a higher tolerance index (TI), and a lower shikimic acid accumulation and foliar retention than the hairy fleabane S population. Absorption and translocation, leaf morphology and metabolism studies were only carried out in the Mexican cologania T population and the hairy fleabane S population. The latter absorbed 37% more (14)C-glyphosate compared to the Mexican cologania T at 96 h after treatment (HAT). Mexican cologania T translocated less herbicide from the treated leaf to the remainder of the plant than hairy fleabane S. The Mexican cologania T presented a greater epicuticular wax coverage percentage than the hairy fleabane S. This morphological characteristic contributed to the low glyphosate absorption observed in the Mexican cologania. In addition, the Mexican cologania T metabolized glyphosate mainly into AMPA, formaldehyde and sarcosine. These results indicate that the high glyphosate tolerance observed in Mexican cologania is mainly due to the poor penetration and translocation of glyphosate into the active site, and the high glyphosate degradation into non-toxic substances.

    Context Characterizing where people die is needed to inform palliative care programs in Mexico. Objectives To determine whether access to health care influences the place of death of older Mexicans and examine the modifying effects of demographic and clinical characteristics. Methods We analyzed 2001 baseline and 2003 follow-up data from the Mexican Health and Aging Study. Cases included adults who completed the baseline interview and died before the follow-up interview and for whom a proxy interview was obtained in 2003. The main outcome variable was the place of death (hospital vs. home). The predictors of the place of death were identified using logistic regression analysis. Results The study group included 473 deceased patients; 52.9% died at home. Factors associated with hospital death were having spent at least one night in a hospital during the last year of life (odds ratio [OR]: 6.73; 95% confidence interval [CI]: 3.29, 13.78) and dying in a city other than the city of usual residence (OR: 4.68, 95% CI: 2.56, 8.57). Factors associated with home death were not having health care coverage (OR: 2.78, 95% CI: 1.34, 5.88), living in a city of less than 100,000 residents (OR: 2.44, 95% CI: 1.43, 4.17), and older age (OR: 1.03, 95% CI: 1.01, 1.05). Conclusion Older Mexicans with access to health care services were more likely to die in the hospital even after controlling for important clinical and demographic characteristics. Findings from the study may be used to plan the provision of accessible end-of-life hospital and home-based services. PMID:21146354

    Parental influences on youth drinking are well documented but not the influence of extended family members. This article explores extended family influences on alcohol use among Mexican youths and whether extended family members can be considered natural mentors. We conducted a qualitative study using ethnographic open ended interviews with 117 first year university students in Mexico City. The ethnographic interviews revealed six drinking groups: excessive, heavy, regular, occasional, abstainers and non drinkers. Youths reported close relationships with extended family members who provided counsel and acted as representatives of familial norms and values. The alcohol beliefs and behaviors of these family members, including their alcohol misuse, had a positive influence on youths’ alcohol attitudes. The naturally occurring mentoring relationships of Mexican extended family members can positively influence moderate youth drinking. Natural mentoring relationships should be encouraged and facilitated in prevention efforts for Mexican youths, Mexican-American youths and potentially other Hispanic/Latino youths. PMID:26187913

    East boundary ecosystems are the most productive regions in the world and they sustain a large percentage of world fisheries. Understand and describe the connectivity and exchange between different regions of the ocean is very important for larvae dispersion study and other tracers like pollutants. In this work we use an offline numerical model to simulate Lagrangian particle trajectories in the Eastern Mexican Pacific (between 120-94 W and 12-34 N). Particles are advected whit velocity fields generated with the model ROMS (Regional Ocean Modeling System) in the period 1980-2006. We define connectivity indexes in order to classify different zones by their capacity of exporting, receiving and retaining particles. We aim to identify the most transited pathways, quantify connectivity between different regions of EMP through connectivity matrix and describe their seasonal variability. It has been identified zones of high isolation and retention (Vizcaino Bay, Northern of Gulf of California), high retention and importation (between Ensenada and Point Conception) and high exportation and importation (Cabo Corrientes). Connectivity has clear equatoward preference in the California Peninsula region dominated by the influence of California Current with an increase in winter and spring, and also equatoward in the south region of Mexico (from Cabo Corrientes to Tehuantepec Gulf), dominated by the anticyclonic circulation of Tehuantepec Dome. It is observed a complete disconnection between the Baja California Peninsula and Cabo Corrientes zone and further south. Results suggest that the scales of connectivity does not significantly change for simulations over 3 months.

    This study qualitatively examines contrasting parental decision-making styles about family food choices and physical activities as well as willingness to change behaviors among Mexican-American and Mexican immigrant mothers and fathers of school-aged children. Twelve sex-specific focus groups were held in English or Spanish in 2012. Qualitative analysis informed by grounded theory examined parenting styles (ie, authoritative, authoritarian, or permissive), barriers to healthy lifestyle, and parents' stage of change about healthy lifestyles. One third of the 33 participating couples were born in Mexico. The majority of mothers and fathers described being permissive and allowing unhealthy food choices, and a minority of mothers reported more authoritarian approaches to promoting a healthier diet for their children. Mothers were more permissive than fathers about family physical activities and less engaged in these activities. Most mothers and fathers described only contemplating a healthier diet and more physical activity, while wanting their children to have a healthier lifestyle. These data suggest that clinicians need to assess and address differential parental roles when promoting a healthy lifestyle for children. Clinicians should also adopt culturally competent approaches to overcome barriers to parental engagement in diverse aspects of a healthy family lifestyle. PMID:24529984

    Research on drug trafficking has not been able to discern the exact nature of illegal drug markets and the relationship between their individual and group participants. This article delineates the role of Mexican immigrants and Mexican-American participants involved in the stratified drug market of South Texas. This article synthesizes ethnographic materials drawn from two previous National Institute on Drug Abuse (NIDA) studies in order identify the different types of drug distribution behaviors that occur within the groups, the differentiated roles of individuals, the organizational framework, and most significantly, the processes that link market participants to others outside of the drug market. This illegal behavior can be interpreted as an adaptive mechanism that is a direct response to the marginal economic status imposed by macro socio-economical background factors. As well, we conclude that the specific foreground factors of the opportunities offered by the context, culture, and proximity of the U.S./Mexico border and invitational edges explain this behavior. There are both parallels and particular differences between the South Texas case and the structuring and functioning of informal legal and illegal markets that are characteristic of other economically disadvantaged communities.

    Using a collective case study ethnographic approach, nine individuals comprising three Mexican American families were interviewed about their family bereavement experiences after the death of a child. All families were Catholic, had surviving siblings, and had had three or more years to grieve their loss when interviewed. The deceased children ranged in age from 3 to 14, and all experienced sudden, traumatic, nonsuicide deaths. To provide a broader, contextual picture of their grief experiences, four individuals who supported these family members after the loss were also interviewed. Unique grief experiences were identified, and eight common themes emerged, reflecting the ways in which family members maintained their bond to the deceased: dreams, storytelling, keepsakes, sense of presence, faith-based connections, proximity connections, ongoing rituals, and pictorial remembrances. The cultural implications of family bereavement are highlighted. PMID:16719572

    A Spanish-language translation of the Wechsler Adult Intelligence Scale-III (WAIS-III), normed in Mexico, is sometimes used when evaluating Spanish-speaking defendants in capital cases in order to diagnose possible mental retardation (MR). Although the manual for the Mexican test suggests use of the U.S. norms when diagnosing MR, the Mexican norms-which produce full-scale scores on average 12 points higher-are sometimes used for reasons that are similar to those used by proponents for "race-norming" in special education. Such an argument assumes, however, that the Mexican WAIS-III norms are valid. In this paper, we examined the validity of the Mexican WAIS-III norms and found six very serious problems with those norms: (1) extremely poor reliability, (2) lack of a meaningful reference population, (3) lack of score normalization, (4) exclusion of certain groups from the standardization sample, (5) use of incorrect statistics and calculations, and (6) incorrect application of the true score confidence interval method. An additional problem is the apparent absence of any social policy consensus within Mexico as to the definition and boundary parameters of MR. Taken together, these concerns lead one to the inescapable conclusion that the Mexican WAIS-III norms are not interpretable and should not be used for any high-stakes purpose, especially one as serious as whether a defendant should qualify for exemption against imposition of the death penalty.

    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. PMID:24743050

    Tuberculosis (TB) and its co-morbid conditions have become a burden on global health economies. It is well understood that susceptibility of the host to TB infection/disease is influenced by both genetic and environmental factors and their interactions. The aims of this pilot case-control study are to characterize the sociodemographic and environmental factors related to active TB disease (TB/case) and latent TB infection (LTBI/control) status, and to identify risk factors associated with progression from LTBI to TB. We recruited 75 cases with TB (mean age=46.3y; females=41%) and 75 controls with LTBI (mean age=39.0y; females=37%), from the Mestizo population of Cuidad Juárez, Mexico. In addition to the determination of case/control status, information on environmental variables was collected (e.g., socioeconomic status, smoking, alcohol consumption, substance abuse, nutritional status, household demographics, medical histories and presence of type 2 diabetes [T2DM]). The data were analyzed to identify the environmental correlates of TB and LTBI using univariate and multivariate statistical approaches. Following multivariate logistic regression analysis, TB was associated with poor nutrition, T2DM, family history of TB, and non-Chihuahua state of birth. These preliminary findings have relevance to TB control at the Mexico-United States border, and contribute to our future genetic study of TB in Mexicans.

    This article details the use of qualitative data in the construction of a Spanish-language, quantitative research instrument designed for a study of Mexican migrant farmworkers' participation in tuberculosis screening. In the qualitative study, 19 Mexican migrant farmworkers were interviewed in Spanish to elicit their explanatory models (EMs) about tuberculosis. The Tuberculosis Interview Instrument (TII) was developed from the results of the qualitative study and concepts from a theoretical framework consisting of a combination of the Health Belief Model (HBM) and the Theory of Reasoned Action (TRA). After its development, the TII was subjected to translation and back-translation procedures to insure the equivalency of the English and Spanish versions, and it was reviewed for content validity. Internal consistency reliability, based on the responses of 206 subjects, was satisfactory for all subscales. Future testing of the TII is recommended to evaluate its stability among Mexican migrant farmworkers in other parts of the United States.

  7. Social actors and discourse on abortion in the Mexican press: the Paulina case.

    PubMed

    Taracena, Rosario

    2002-05-01

    The "Paulina case" is the story of a 13-year-old girl in Mexico who became pregnant in 1999 after being raped. Although she received permission to obtain a legal abortion, the hospital convinced her mother through misleading information to decline the abortion. This case has become an almost obligatory point of reference when abortion is discussed in Mexico. This paper analyses how the Mexican press portrayed the Paulina case and the social actors who participated in it--Paulina herself, Paulina's allies, the state government, the Catholic Church, members of the political party PAN and the National Human Rights Commission. One of the great breakthroughs of this case was that the denial of an abortion was judged to be a form of negligence. In demanding justice for Paulina, Paulina's allies were given moral authority in the press to denounce those who denied her an abortion. While the government of Baja California state and members of the PAN were held responsible for their role in the case, the Catholic Church, who was also responsible, seemed to escape criticism. It is probable that the large emotional weight of the Paulina case accomplished more in terms of changing public opinion in support of women's right to decide on abortion than any other single event to date.

    This study analyzed the prospective relationship of community social disorder with sedentary behavior, sport participation, and adiposity in Mexican adults from the National Mexican Family Life Survey (MxFLS). The sample included 8307 adults (aged ≥20 years) from 145 communities. During a three-year follow-up, participants from communities with high social disorder had a 1.36cm larger increase in waist circumference than participants from communities with low social disorder. However, there were no differences in body mass index, television, or sport participation. These findings emphasize the need to promote healthy social environments in local communities.

  16. Study on genes of the serotonergic system and suicidal behavior: protocol for a case–control study in Mexican population

    PubMed Central

    2014-01-01

    Background Suicidal behavior is a leading cause of injury and death worldwide. Several studies have provided a possible relationship between genetic factors and suicidal behavior. Also, these studies have shown evidence for altered serotonergic neural transmission in the pathogenesis of suicidal behavior. In addition, genes pertaining to the serotonergic system have been proposed as candidates to establish biological correlates between suicidal behavior and the serotonergic system. The most studied genes are SCL6A4, HTR2A, HTR2C, HTR1A, HTR1B, TPH-1, and TPH-2. To get a comprehensive understanding of the association with suicidal behavior we will conduct genotype assays studies in a Mexican population. Methods/Design We will conduct a case–control study. The population sample will comprise adolescent and adult patients admitted for attempted of suicide and diagnosed by a psychiatrist. A peripheral blood sample will be taken from all the subjects (cases and controls). Genomic DNA from the leukocytes blood sample will be extracted. The genotypes of interest are distributed in the following genes: SCL6A4, HTR2A, HTR1A, HTR1B, HTR2C, TPH-2 and TPH-1. All the samples will be analyzed using a polymerase chain reaction (PCR) end-point method. We will evaluate the Hardy-Weinberg Equilibrium. The chi-squared test or Fisher’s exact test will be used to compare genotype and allele frequencies between control and case groups. The Quanto 1.2 software will measure the sample size of the association. For all the association analyses the level of significance will be set at p = 0.05 and the confidence interval at 95%. Discussion Suicidal behavior has been increase in Mexico, principally in young population. Our study will demonstrate the association between serotoninergic genes and suicide behavior in Mexican population. PMID:24495559

    Mexican-origin families are a large and rapidly increasing subgroup of the U.S. population, but they remain underrepresented in family scholarship. This paper introduces a special section of four papers on Mexican-origin families designed to contribute to the advancement of research on how cultural, family, and gender socialization processes unfold across key developmental periods and life transitions in this cultural context. Two longitudinal studies of Mexican-origin families provided the data for these four papers: (a) The Juntos Project, an 8-year longitudinal study of mothers, fathers, and adolescent sibling pairs in 246 Mexican-origin families; and (b) The Supporting MAMI Project, a study following 204 adolescent mothers and their mother figures from the third trimester of pregnancy through their young children's 5th birthdays. In this introductory paper, we highlight four themes, including (a) differential acculturation and reciprocal socialization, (b) interdependence in families, (c) the intersection of culture and gender, and (d) methodological issues. We end with suggestions for future research. PMID:25675994

    Obsessive-compulsive disorder (OCD) is a psychiatric disorder whose etiology is not yet known. We investigate the role of three variants of the BDNF gene (rs6265, rs1519480 and rs7124442) by single SNP and haplotype analysis in OCD Mexican patients using a case-control and family-based association design. BDNF gene variants were genotyped in 283 control subjects, 232 OCD patients and first degree relatives of 111 OCD subjects. Single SNP analysis in case-control study showed an association between rs6265 and OCD with a high frequency of Val/Val genotype and Val allele (p=0.0001 and p=0.0001, respectively). Also, genotype and allele analysis of rs1519480 showed significant differences (p=0.0001, p=0.0001; respectively) between OCD and control groups. Haplotype analysis showed a high frequency of A-T (rs6265-rs1519480) in OCD patients compared with the control group (OR=2.06 [1.18-3.59], p=0.0093) and a low frequency of haplotype A-C in the OCD patients (OR=0.04 [0.01-0.16], p=0.000002). The family-based association study showed no significant differences in the transmission of any variant. Our study replicated the association between BDNF Val66Met gene polymorphism and OCD. Also, we found a significant association of rs1519480 in OCD patients compared with a control group, region that has never been analyzed in OCD. In conclusion, our findings suggest that BDNF gene could be related to the development of OCD.

    Background/objective Children of Mexican descent frequently experience household food insecurity both in the United States (US) and Mexico, however, little is known about the associations of food insecurity with dietary intake. This study aimed to understand the level of perceived food insecurity and its association with dietary intake among children of Mexican descent residing in the US and Mexico. Design This cross-sectional study utilized data from a 2006 binational study of five-year-old children of Mexican descent living in migrant communities in California (CA) and Mexico (MX). Methods In CA, children were 301 participants from the CHAMACOS study, a longitudinal birth cohort in a Mexican immigrant community. MX children (n=301) were participants in the Proyecto Mariposa study, which was designed to capture a sample of women and their children living in Mexico who closely resembled the CA sample, yet who never migrated to the US. Household food insecurity was measured using the US Department of Agriculture Food Security Scale and dietary intake was assessed with food frequency questionnaires. Analysis of variance was used to examine unadjusted and adjusted differences in total energy, nutrient intake, and consumption of food groups by household food security status. Results Approximately 39% of the CA mothers and 75% of the MX mothers reported low or very low food security in the last 12 months (p<0.01). Children in the US, experiencing food insecurity consumed more fat, saturated fat, sweets and fried snacks than children not experiencing food insecurity. In contrast, in Mexico food insecurity was associated with lower intake of total carbohydrates, dairy and vitamin B6. Conclusions Programs and policies addressing food insecurity in the US and Mexico may need to take steps to address dietary intake among children in households experiencing food insecurity, possibly through education and programs to increase resources to obtain healthy foods.

    2014-01-01

    Background Studies of domestication enables a better understanding of human cultures, landscape changes according to peoples’ purposes, and evolutionary consequences of human actions on biodiversity. This review aimed at discussing concepts, hypotheses, and current trends in studies of domestication of plants, using examples of cases studied in regions of Mesoamerica and Brazil. We analyzed trends of ethnobiological studies contributing to document processes of domestication and to establish criteria for biodiversity conservation based on traditional ecological knowledge. Methods Based on reviewing our own and other authors’ studies we analyzed management patterns and evolutionary trends associated to domestication occurring at plant populations and landscape levels. Particularly, we systematized information documenting: ethnobotanical aspects about plant management and artificial selection mechanisms, morphological consequences of plant management, population genetics of wild and managed plant populations, trends of change in reproduction systems of plants associated to management, and other ecological and physiological aspects influenced by management and domestication. Results Based on the analysis of study cases of 20 native species of herbs, shrubs and trees we identified similar criteria of artificial selection in different cultural contexts of Mexico and Brazil. Similar evolutionary trends were also identified in morphology (selection in favor of gigantism of useful and correlated parts); organoleptic characteristics such as taste, toxicity, color, texture; reproductive biology, mainly breeding system, phenological changes, and population genetics aspects, maintenance or increasing of genetic diversity in managed populations, high gene flow with wild relatives and low structure maintained by artificial selection. Our review is a first attempt to unify research methods for analyzing a high diversity of processes. Further research should emphasize deeper

    The purpose of this study was to identify prerequisites to providing culturally competent care to Mexican migrant farmworkers. A national sample of nurse experts who worked with Mexican migrant farmworkers (N = 93 [50.2%] in round 1; and N = 142 [54.8%] in round 2) participated during the period of August 1998 to April 1999. Using a two-round modified Delphi method, a list of 89 items was generated. The nurse experts agreed that the 89 items identified were prerequisites to cultural competence, showing consensus rates of 85.4% in round 1 and 88.8% in round 2. The prerequisites to culturally competent care identified by participants encompassed caring, cultural sensitivity, cultural knowledge (general/specific), cultural abilities/skills, and others (bi-cultural status; cultural and learning experiences).

    Power, Thomas G.

    2010-01-01

    Objective To assess longitudinally the relations between four parenting styles (authoritative, authoritarian, uninvolved, and indulgent) and child weight status in Mexican American families. Methods Sixty-nine low-income Mexican American mothers and their 4- to 8-year-old children participated in a 4-year longitudinal study. Mothers completed demographic and parenting measures. Children's body weight and height were assessed annually. Body mass index was calculated to determine weight status. Results At baseline, 65% of children were found to be normal weight, 14% were overweight, and 21% were obese. Analyses examined how parenting styles at baseline predicted child's weight status 3 years later, controlling for initial weight status. Children of indulgent mothers were more likely to become overweight 3 years later than children of authoritative or authoritarian mothers. Conclusions This study provides longitudinal evidence for the role of indulgent parenting in predicting overweight in Mexican American children. Possible mediating factors that may account for this relationship (e.g., dietary patterns, physical activity patterns, and children's self-regulation) are considered. PMID:19726552

    Although pica, the craving and purposive consumption of non-food substances, is common among many populations, especially during pregnancy, the health consequences are not well understood. Further, very little is known about pica among Mexican populations in the US and Mexico. Therefore, we conducted formative research to understand pica in this understudied population. Our objectives were to identify the frequency and types of pica behaviors, understand perceived etiologies and consequences of pica, and to ascertain if the behavior was common enough to warrant a larger study. We held 9 focus group discussions (FGDs, 3 in the Salinas Valley, California, 6 in Xoxocotla, Morelos, Mexico) with 76 Mexican-born women who were currently pregnant or had delivered within the past two years. Earth, adobe, bean stones, and ice were the most commonly reported pica substances. Twenty-eight of the 76 participants (37%) reported ever engaging in pica; 22 participants (29%) reported doing so during pregnancy. The proportion of women reporting pica in the US was 43% and 34% in Mexico. Women attributed pica to the overwhelming organoleptic appeal of pica substances (especially smell and texture) and to micronutrient deficiencies. Perceived consequences of unfulfilled pica cravings were birthmarks or fetal loss; fulfilled pica cravings were also thought to be generally harmful to the mother or child, with several women specifying toxic lead, pesticides, or “worms”. In sum, pica among Mexican women is common enough to warrant a larger epidemiologic study of its socio-demographic correlates and physiological consequences. PMID:24784797

  17. Racial Formation in Theory and Practice: The Case of Mexicans in the United States

    PubMed Central

    2010-01-01

    Mechanisms of social stratification require the categorical definition of an out-group to that can be excluded and exploited. Historically, in the United States, African Americans have been the subject of a systematic process of racial formation to define socially in this fashion. Beginning in the 1970s, however, and accelerating in the 1980s and 1990s, Mexicans were increasingly subject to processes of racialization that have rendered them more exploitable and excludable than ever before. Over the past decade, Mexican Americans moved steadily away from their middle position in the socioeconomic hierarchy and gravitated toward the bottom. This paper describes the basic mechanisms of stratification in the United States and how Mexicans have steadily been racialized to label them socially as a dehumanized and vulnerable out-group.

    2016-01-01

    Introduction Calf circumference is a surrogate measurement of muscle mass. However, there is scarce evidence on its validity in predicting adverse outcomes such as mobility disability. The aim of this report is to determine if calf circumference could predict incident mobility disability in Mexican 60-year or older adults. Methods This is a secondary analysis of the Mexican Health and Aging Study and in particular of its two first waves. Sixty-year or older adults without mobility disability in the first assessment were included and followed-up for two years. Calf circumference quartile groups were compared to test the difference of incident mobility disability. Logistic regression models were fitted to test the independent association when including confounding variables. Results A total of 745 older adults were assessed, from which 24.4% of the older adults developed mobility disability at follow-up. A calf circumference > 38 cm was associated with a higher risk of developing mobility disability, even after adjustment in the multivariate model, with an odds ratio 0.55 (95% confidence interval 0.31–0.99, P = 0.049). Conclusions High calf circumference in Mexican older adults is independently associated with incident mobility disability. This could reflect the impact of adverse health conditions such as obesity (with high fat tissue) or edema. Further research should aim at testing these results in different populations.

    1995-11-01

    Adverse pregnancy outcomes such as low birth weight are increased among US-born mothers of Mexican descent compared with immigrant mothers born in Mexico. It is unknown whether adverse reproductive outcomes change among Mexican immigrants after only 5 years of US residence. The authors conducted a study of 1,114 Mexican immigrant mothers and their infants in two California counties. The relation between US residence status and birth outcomes was examined, controlling for sociodemographic factors and maternal behaviors. Long-term immigrants who have lived in the United States for more than 5 years were more likely to deliver preterm infants (odds ratio (OR) = 1.9, 95% confidence interval (CI) 1.1-3.3) and low birth weight infants (OR = 1.5, 95% CI 0.8-2.7) than newcomers who have lived in the United States for 5 years or less. Long-term immigrants had higher parity, more pregnancy complications, and fewer planned pregnancies, and were more likely to smoke than newcomers. After controlling for confounders, the effect of residence status on preterm delivery was of borderline significance (adjusted OR = 1.8, 95% CI 1.0-3.2). Pregnancy complications was an intervening variable between residence status and preterm delivery. Length of US residence is associated with an increase in low birth weight via a decrease in gestational age rather than intrauterine growth retardation.

    Objective To evaluate the prevalence of hypertension in older Mexicans in the United States and Mexico. Design Stratified by sex, logistic regression models to predict physician diagnosed hypertension were conducted using the Hispanic EPESE (wave 3) and the Mexican Health and Aging Study (MHAS- 70 years and older) datasets. Setting Five Southwestern States of Texas, Arizona, California, Colorado, and New Mexico in the United States. Participants Older Mexican and Mexican Americans ages 70 and over living in the United States and Mexico. Main Outcome Measures Physician diagnosed hypertension. Results Older Mexican and Mexican American women have a greater prevalence of hypertension than their male counterparts. Mexican women, who have migrated to the United States and returned to Mexico, have similarly high rates of hypertension as their female counterparts in the United States. After adjusting for demographic characteristics, obesity, and smoking, older Mexican and Mexican American women who have migrated or immigrated to the United States are at increased risk for hypertension. Conclusions Gender differences exist in hypertension risk for older Mexicans and Mexican Americans living in the United States and Mexico. Older women who migrate to the United States are at a particular risk for hypertension in both the United States and Mexico. PMID:18785442

    Read, Jen'nan Ghazal; Reynolds, Megan M

    2012-03-01

    This article draws on theories of gender inequality and immigrant health to hypothesize differences among the largest immigrant population, Mexicans, and a lesser known population of Middle Easterners. Using data from the 2000-2007 National Health Interview Surveys, we compare health outcomes among immigrants to those among U.S.-born whites and assess gender differences within each group. We find an immigrant story and a gender story. Mexican and Middle Eastern immigrants are healthier than U.S.-born whites, and men report better health than women regardless of nativity or ethnicity. We identify utilization of health care as a primary mechanism that contributes to both patterns. Immigrants are less likely than U.S.-born whites to interact with the health care system, and women are more likely to do so than men. Thus, immigrant and gender health disparities may partly reflect knowledge of health status rather than actual health.

    Produce is responsible for an increasingly larger proportion of foodborne disease outbreaks. In particular, the globalization of the food supply may introduce new food safety risks and allow widespread distribution of contaminated food, particularly produce. The objectives of this study were to: (i) compare the overall quality of domestic and Mexican produce throughout the packing process; (ii) examine changes in microbiological quality of both domestic and Mexican produce at each stage of production and processing; and (iii) evaluate the prevalence of select pathogens on fresh produce, including leafy green, herbs, melons, and vegetables. Furthermore, we also sought to characterize the antibiotic resistance profiles of Enterococcus faecium and Enterococcus faecalis strains isolated from fresh produce. A total of 466 produce and matching environmental swab samples was collected from various locations in packing sheds in the southern US from November 2002 through December 2003. These samples were assayed by enumerative tests for total aerobic bacteria (APC), total coliforms, total Enterococcus, and E. coli. Produce samples were also analyzed for the presence of Salmonella, Listeria monocytogenes, Shigella, and E. coli O157:H7. A total of 112 E. faecium and E. faecalis isolates were further screened for antibiotic resistance using a panel of seventeen antibiotics. Overall, the microbiological quality of fresh produce ranged from 4.0 to 7.9 log(10) CFU/g (APC); less than 1.0 log(10) to 4.5 log(10) CFU/g (coliforms); less than 1.0 log(10) to 4.0 log(10) CFU/g (E. coli); and less than 1.0 log(10) to 5.4 log(10) CFU/g (Enterococcus). No Salmonella, Shigella, or E. coli O157:H7 were detected from the 466 25-g produce samples tested. However, three domestic cabbage samples were found to be positive for L. monocytogenes. Of the Enterococcus isolates, E. faecium had a higher degree of resistance to antibiotics in general, while Enterococcus spp. isolated from Mexican produce

    2003-05-01

    We present a chemical-reaction model to describe the Mexican wave ( La Ola) in football stadia. The spectator's action is described in terms of chemical reactions. The model is governed by three reaction rates k 1, k 2, and k3. We study the nonlinear waves on one- and two-dimensional lattices. The Mexican wave is formulated as a clockwise forwardly propagating wave. Waves are growing or disappear, depending on the values of reaction rates. In the specific case of k1= k2= k3=1, the nonlinear-wave equation produces a propagating pulse like soliton.

    Mexican American youth are at greater risk of school failure than their peers. To identify factors that may contribute to academic success in this population, this study examined the prospective relationships from 5th grade to 7th grade of family (i.e., human capital [a parent with at least a high school education], residential stability, academically and occupationally positive family role models, and family structure) and individual characteristics (i.e., externalizing symptoms, bilingualism, gender, and immigrant status) to the academic performance of 749 Mexican American early adolescents (average age = 10.4 years and 48.7% were girls in 5th grade) from economically and culturally diverse families as these youth made the transition to junior high school. Results indicated that while controlling for prior academic performance, human capital and positive family role models assessed when adolescents were in 5th grade positively related to academic performance in 7th grade. Further, being a girl also was related to greater 7th grade academic success, whereas externalizing symptoms were negatively related to 7th grade academic performance. No other variables in the model were significantly and prospectively related to 7th grade academic performance. Implications for future research and interventions are discussed.

    Spinocerebellar ataxia type 7 (SCA7) is an inherited neurodegenerative disorder characterized by progressive cerebellar ataxia associated with macular degeneration. We recently described one of the largest series of patients with SCA7 that originated from a founder effect in a Mexican population, which allowed us to perform herein the first comprehensive clinical, neurophysiological, and genetic characterization of Mexican patients with SCA7. In this study, 50 patients, categorized into adult or early phenotype, were clinically assessed using standard neurological exams and genotyped using fluorescent PCR and capillary electrophoresis. Patients with SCA7 exhibited the classical phenotype of the disease characterized by cerebellar ataxia and visual loss; however, we reported, for the first time, frontal-executive disorders and altered sensory-motor peripheral neuropathy in these patients. Semiquantitative analysis of ataxia-associated symptoms was performed using Scale for the Assessment and Rating of Ataxia (SARA) and the Brief Ataxia Rating Scale (BARS) scores, while extracerebellar features were measured employing the Inventory of Non-ataxia Symptoms (INAS) scale. Ataxia rating scales confirmed the critical role size of cytosine-adenine-guanine (CAG) repeat size on age at onset and disease severity, while analysis of CAG repeat instability showed that paternal rather than maternal transmission led to greater instability.

  17. Presidential and bureaucratic policy-making: The case of Mexican oil policy

    1991-01-01

    A close examination of the literature yielded two different, but vague models of Mexican policy-making: (1) closed presidential policy-making and (2) open presidential policy-making. These two models are tested by identifying the regime's policy-making structures and by explaining the manner in which they operated to produce oil policy in two presidential administrations. To attain these goals, the oil policy-making process was divided into several stages. The policy roles played by different actors in the various stages of policy-making were analyzed. The process they engaged in to produce oil policy was also examined. The findings lend strong support to the open presidential policy-making model. The most salient features of this model are: (1) the president and different members of the Mexican federal bureaucracy share policy-making functions, power, and influence; (2) policymakers engage in a political process of persuasion, coalition building, information functions, power, and influence; and (3) policymakers engage in these and other political techniques to produce government decisions and actions.

    Latin American audiences living in their countries of origin are poorly understood as museum learners due to the scarcity of research in this field. Through a case study approach, I investigate and report on the ways of learning of 20 Mexican family groups. In particular, I examine the influence of the Mexican sociocultural context on the participant family members' learning outcomes from a Mexican science museum. Conducted in Universum Museo de las Ciencias, a science museum located in Mexico City, this research study is based on the premise that understanding the role of the sociocultural elements of learning is essential to understanding the nature of learning in museums. The cognitive and social outcomes of the participants are discussed in the light of the sociocultural elements that define Mexicans as museum learners.

    2015-01-01

    Mexican-origin families are a large and rapidly increasing subgroup of the U.S. population, but they remain underrepresented in family scholarship. This paper introduces a special section of four papers on Mexican-origin families designed to contribute to the advancement of research on how cultural, family, and gender socialization processes unfold across key developmental periods and life transitions in this cultural context. Two longitudinal studies of Mexican-origin families provided the data for these four papers: (a) The Juntos Project, an eight-year longitudinal study of mothers, fathers, and adolescent sibling pairs in 246 Mexican-origin families; and (b) The Supporting MAMI Project, a study following 204 adolescent mothers and their mother figures from the third trimester of pregnancy through their young children's 5th birthdays. In this introductory paper we highlight four themes, including (a) differential acculturation and reciprocal socialization, (b) interdependence in families, (c) the intersection of culture and gender, and (d) methodological issues, then offer suggestions for future research.

    2009-01-01

    Background Mounting evidence indicates that HLA-mediated HIV evolution follows highly stereotypic pathways that result in HLA-associated footprints in HIV at the population level. However, it is not known whether characteristic HLA frequency distributions in different populations have resulted in additional unique footprints. Methods The phylogenetic dependency network model was applied to assess HLA-mediated evolution in datasets of HIV pol sequences from free plasma viruses and peripheral blood mononuclear cell (PBMC)-integrated proviruses in an immunogenetically unique cohort of Mexican individuals. Our data were compared with data from the IHAC cohort, a large multi-center cohort of individuals from Canada, Australia and the USA. Results Forty three different HLA-HIV codon associations representing 30 HLA-HIV codon pairs were observed in the Mexican cohort (q < 0.2). Strikingly, 23 (53%) of these associations differed from those observed in the well-powered IHAC cohort, strongly suggesting the existence of unique characteristics in HLA-mediated HIV evolution in the Mexican cohort. Furthermore, 17 of the 23 novel associations involved HLA alleles whose frequencies were not significantly different from those in IHAC, suggesting that their detection was not due to increased statistical power but to differences in patterns of epitope targeting. Interestingly, the consensus differed in four positions between the two cohorts and three of these positions could be explained by HLA-associated selection. Additionally, different HLA-HIV codon associations were seen when comparing HLA-mediated selection in plasma viruses and PBMC archived proviruses at the population level, with a significantly lower number of associations in the proviral dataset. Conclusion Our data support universal HLA-mediated HIV evolution at the population level, resulting in detectable HLA-associated footprints in the circulating virus. However, it also strongly suggests that unique genetic

    2015-01-01

    Family legal status is a potentially important source of variation in the health of Mexican-origin children. However, a comprehensive understanding of its role has been elusive due to data limitations and inconsistent measurement procedures. Using restricted data from the 2011-2012 California Health Interview Survey, we investigate the implications of measurement strategies for estimating the share of children in undocumented families and inferences about how legal status affects children's health. The results show that inferences are sensitive to how this “fundamental cause” is operationalized under various combinatorial approaches used in previous studies. We recommend alternative procedures with greater capacity to reveal how the statuses of both parents affect children's well-being. The results suggest that the legal statuses of both parents matter, but the status of mothers is especially important for assessments of child health. The investigation concludes with a discussion of possible explanations for these findings. PMID:26056934

    This study explored how couples of Mexican origin define power in intimate relationships, what makes men and women feel powerful in relationships, and the role of each partner in decision making about sexual and reproductive matters. Interviews were conducted with each partner of 39 sexually active couples and data were analyzed using content analysis. Results indicate that power is perceived as control over one s partner and the ability to make decisions. Women say they feel more powerful in relationships when they make unilateral decisions and have economic independence. Men feel powerful when they have control over their partner and bring home money. Respondents agreed that women make decisions about household matters and children, while men make decisions related to money. Findings indicate that whereas couples share decision making about sexual activities and contraceptive use, men are seen as initiators of sexual activity and women are more likely to suggest condom use.

  12. The labor market experience of female migrants: the case of temporary Mexican migration to the U.S.

    Kossoudji, S A; Ranney, S I

    1984-01-01

    This article, using a Mexican national survey, provides a profile of temporary Mexican female migrants in the US labor market. The usual association between occupational groups and wage rates does not hold up, with women in unskilled jobs averaging nearly the same wages as while collar women. The dramatic exception is private household workers, who earn less than 1/4 of the wage rates of other women. Although the distribution of wage rates across occupational groups for migrant women is not easily explained by schooling or potential work experience, wage rates seem to be positively correlated with marriage and childrearing. This is partly explained by the fact that married women are more likely to have the option of not working outside the home, and also that the labor market contacts provided by husbands may be helpful in securing more remunerative jobs. Migration networks make the region of origin in Mexico strongly correlate with wage rate variations across occupational groups for women. Although women are found to have more schooling, higher legal status, more US work experience and are more likely to come from regions with well developed migration networks than men, women average upto $7 less per day--a phenomenon largely explained by the labor market segmentation. A lack of legal status constrains women's job opportunities more than men's: over 90% of the women without entry permits are in the low paying private household sector, compared with less than 1/4 of those with some legal status. This connection between lack of proper legal status and low status jobs does not seem to prevent women from migrating illegally--more than 1/2 the women migrant studied had no legal status at all. This study concludes that women do not necessarily follow men in migration, and their labor market functions are quite distinct from those of men.

    This cross-sectional study aimed at identifying the most common attributions of their mental disorder in a Mexican patients who have experienced psychosis and their relatives and exploring how having experienced or not characteristic psychotic symptoms and their present clinical status might affect their etiological attributions. Past and current symptom profiles of 66 patients were as assessed with the SCID-I (Structured Clinical Interview for DSM-IV Axis I Disorders) and the PANSS (Positive and Negative Syndrome Scale), respectively. The etiological attribution of psychosis of patients (n = 62) and the relatives (n = 65) was assessed with the Angermeyer and Klusmann scale comprising 30 items into five categories: biology, personality, family, society, and esoteric. Patients and relatives attribute psychosis mainly to social factors. Relatives' attributions were not influenced by clinical profile of patients, whereas in the case of patients it was only current clinical status that showed a difference, with those in nonremission scoring higher personality and family factors. Acknowledging patients' and relatives' beliefs about mental disorders at onset and later on is particularly important in psychosis, a mental condition with severe and/or persistent symptoms, in order to promote better involvement in treatment and in consequence efficacy and recovery.

Individuals with moderate-to-severe non-proliferative and proliferative diabetic retinopathy were defined as cases. Direct genotyping was performed using the Affymetrix GeneChip Human Mapping 100 K Set, and SNPs passing quality control criteria were used to impute markers available in HapMap Phase III Mexican population (MXL) in Los Angeles, California. Two directly genotyped markers were associated with severe diabetic retinopathy at a P-value less than .0001: SNP rs2300782 (P = 6.04 × 10−5) mapped to an intron region of CAMK4 (calcium/calmodulin-dependent protein kinase IV) on chromosome 5, and SNP rs10519765 (P = 6.21 × 10−5) on chromosomal 15q13 in the FMN1 (formin 1) gene. Using well-imputed markers based on the HapMap III Mexican population, we identified an additional 32 SNPs located in 11 chromosomal regions with nominal association with severe diabetic retinopathy at P-value less than .0001. None of these markers were located in traditional candidate genes for diabetic retinopathy or diabetes itself. However, these signals implicate genes involved in inflammation, oxidative stress and cell adhesion for the development and progression of diabetic retinopathy. PMID:20871662

  18. It's all about the children: a participant-driven photo-elicitation study of Mexican-origin mothers' food choices

    PubMed Central

    2011-01-01

    Background There is a desperate need to address diet-related chronic diseases in Mexican-origin women, particularly for those in border region colonias (Mexican settlements) and other new destination communities in rural and non-rural areas of the U.S. Understanding the food choices of mothers, who lead food and health activities in their families, provides one way to improve health outcomes in Mexican-origin women and their children. This study used a visual method, participant-driven photo-elicitation, and grounded theory in a contextual study of food choices from the perspectives of Mexican-origin mothers. Methods Teams of trained promotoras (female community health workers from the area) collected all data in Spanish. Ten Mexican-origin mothers living in colonias in Hidalgo County, TX completed a creative photography assignment and an in-depth interview using their photographs as visual prompts and examples. English transcripts were coded inductively by hand, and initial observations emphasized the salience of mothers' food practices in their routine care-giving. This was explored further by coding transcripts in the qualitative data analysis software Atlas.ti. Results An inductive conceptual framework was created to provide context for understanding mothers' daily practices and their food practices in particular. Three themes emerged from the data: 1) a mother's primary orientation was toward her children; 2) leveraging resources to provide the best for her children; and 3) a mother's daily food practices kept her children happy, healthy, and well-fed. Results offer insight into the intricate meanings embedded in Mexican-origin mothers' routine food choices. Conclusions This paper provides a new perspective for understanding food choice through the eyes of mothers living in the colonias of South Texas -- one that emphasizes the importance of children in their routine food practices and the resilience of the mothers themselves. Additional research is needed to

    Objective To describe the third wave of the Mexican Health and Aging Study (MHAS), completed in 2012, and present preliminary results. Materials and methods Descriptive analyses by gender and age group of demographic and socioeconomic characteristics, health conditions and health behaviors, as well as social support and life satisfaction measures are presented. In addition, external validations are presented by comparing MHAS 2012 indicators with other national data sources. Results For the panel of older adults in the sample, the rate of health care insurance coverage increased greatly between 2001 and 2012, a significantly higher change in rural compared to urban areas. The results for 2012 are consistent with the previous two waves for the main indicators of health and physical disability prevalence, risk factors, and behaviors. Conclusions The MHAS offers a unique opportunity to study aging in Mexico, as well as to complete cross-national comparisons. The cumulative number of deaths in the cohort should support the study of mortality and its association with health outcomes and behaviors over the life cycle. In addition, the sub-samples of objective markers will enable methodological research on self-reports and associations of biomarkers in old age with similar health outcomes and behaviors.

    SUMMARY This study aimed to estimate the prevalence and risk factors for Hepatitis C Virus (HCV) infection in Mexican Americans living in South Texas. We tested plasma for the presence of HCV antibody from the Cameron County Hispanic Cohort (CCHC), a randomized, population-based cohort in an economically disadvantaged Mexican-American community on the United States/Mexico border with high rates of chronic disease. A weighted prevalence of HCV antibody of 2.3% (n=1131, 95% CI 1.2%–3.4%) was found. Participants with diabetes had low rates of HCV antibody (0.4%, 95% CI 0.0%–0.9%) and logistic regression revealed a statistically significant negative association between HCV and diabetes (OR 0.20 95% CI 0.05–0.77) after adjusting for sociodemographic and clinical factors. This conflicts with reported positive associations of diabetes and HCV infection. No classic risk factors were identified, but important differences between genders emerged in analysis. This population-based study of HCV in Mexican-Americans suggests that national studies do not adequately describe the epidemiology of HCV in this border community and that unique risk factors may be involved.

    The aim of this cross-sectional study was to evaluate the association between socioeconomic indicators and use of dental services in a sample of 3,048 Mexican schoolchildren. The dependent variable 'use of dental services' and independent variables were collected through a questionnaire addressed to mothers. To determine oral health needs, a clinical oral examination was performed. The adjusted associations were evaluated using polytomous logistic regression. Adjusted by gender, the categories associated with both preventive and curative services were age, greater frequency of brushing, earlier initiation of brushing, healthcare coverage, and better socioeconomic status. In addition, for preventive services only, use of services was associated with enrolment in private school, and for curative services only, family's possession of an automobile and having moderate to high oral health needs. The results suggest the existence of socioeconomic inequalities in the use of both preventive and curative dental services by Mexican children.

    Prospective studies on the predictors of postpartum depression (PPD) in Latin America are scarce, which is a matter of importance, since the significance of PPD risk factors may vary according to the level of development of a country, the types of measurement and the time periods assessed. This study identifies the prenatal predictors for PPD (diagnostic interview) and postpartum depressive symptoms (PPDS) (self-report scale) in Mexican mothers at 6 weeks and 6 months postpartum. Two hundred and ten women were interviewed using the Structured Clinical Interview (SCID-I), Patient Health Questionnaire (PHQ-9) and various risk factor scales. Univariate logistic regressions showed that social support, marital satisfaction, life events, a history of psychopathology, anxiety symptoms, depressive symptoms, the traditional female role, previous miscarriages/termination of pregnancy and unplanned/unwanted pregnancy were significant predictors for both PPD and PPDS at both assessment times in the postpartum. Education, age, marital status, income, occupation, parity, C-section and resilience were significant for only one of the measurements and/or at just one assessment time. General findings replicate a high- and low-income country observed psychosocial risk profile and confirm a sociodemographic and obstetric profile of vulnerability that is more prevalent in resource-constrained countries. PPD constitutes a high burden for new mothers, particularly for those living in low-middle-income countries who face social disadvantages (such as low educational attainment and income).

    Participatory research is essential in public health studies, but using this methodology to examine sensitive public health problems among vulnerable populations is a challenge. We share some of our trials and tribulations in attempting to use participatory research in our substance abuse studies among transnational Mexican migrants in southeastern Pennsylvania. Major challenges did not permit partnerships across the community in all phases of research, including the dissemination of findings. Especially difficult was including transnational migrants and nearby relatives as partners in the research, similar to partnerships created with others in the community. The sensitive nature of our research and associated human subject concerns did not permit a more participatory methodology. Another problem involved partnerships with members of the larger community, given the apathy and ambivalence towards drug use by transnational migrants. Finally, collaborating with community stakeholders to develop and implement research-based recommendations was also problematic. As we learned, there are more to generating substance abuse recommendations in partnership with stakeholders than simply working together on recommendations, which also require an effective implementation strategy. Based on these experiences, we elaborate useful suggestions in development and application of local-level programs aimed at curtailing substance abuse among transnational migrant workers while they are at their work sites in Pennsylvania.

    Cytochrome P-450 3A4 (CYP3A4) contributes to the metabolism of approximately half the drugs in clinical use today. The aim of the present study was to determine the frequency of the CYP3A4*1B, *2, *4, *5, and *18 alleles amongst both Tepehuan Amerindians, a native group that has inhabited northern Mexico for thousands of years, and Mestizo Mexicans, and to compare the data with those of other populations. Genotyping experiments revealed that 8.8 and 8.0% of the Mestizo and Tepehuano subjects, respectively, carried the CYP3A4*1B allele. Only one Mestizo subject was heterozygous for the CYP3A4*2 variant, while CYP3A4*4, *5 and *18 allelic variants were not detected in either group. On the other hand, the frequencies of the CYP3A4*1B variant in Mestizos and Tepehuanos were similar to those reported for Caucasians, but different from those observed for African and Asian populations.

    The purpose of this pilot study was to collect data to inform the development of an HIV prevention program for drug-involved Mexican-origin (MO) adolescent girls. Eighteen in-depth semi-structured interviews were conducted with drug-involved MO girls in addition to focus group discussions with nineteen other drug-involved MO girls and eight clinical service providers in 2009-2010. Emergent themes indicated that HIV prevention programs for drug-involved MO girls should be girl-centered, focused on relationship development, and include trained peer facilitators who share the same cultural and "street" background as the girls. The program should omit scare tactics associated with risky sexual behaviors and emphasize individual empowerment skills useful to negotiate sexual decisions successfully. In addition, a girl-centered intervention for MO girls should address important concerns for this group, including resistance skills and strategies regarding relationships with older men, teenage motherhood, sexual infidelity, sexual coercion, and dating violence. Intervention activities should also be interactive with an emphasis on guiding girls as they learn to critically assess personal risk while at the same time learning skills and resources to address these issues in real life.

    Analysis and interpretation of gravimetric anomalies over the Occidental-Central Mexican Volcanic Belt, sheds new light on the subsurface structure of the Ixtlan de los Hervores, geothermal area. In Mexico, there are several geothermal areas that have been exploited commercially (Cerro Prieto, Los Azufres, Los Humeros, Tres Virgenes fields). However, there are many other known fields that have not been exploited. This is the case in the area of "Ixtlan de los Hervores" in the state of Michoacan. The analyzed region covers a rectangular area, aproximality from 20o N to 20.5° N and 102° W to 102.2°W. In the region there are thick basalt flows. The area is characterized by low and elongated hills formed by volcanic flows and on a smaller scale lacustrian sediments and major normal faults with a NW-SE direction particularly, the Ixtlan-Encinal fault which controls the trace of the Duero River and the Pajacuarán fault. The anomaly map was compared with the surface geology and the anomalies were correlated with major volcanic features, since our main interest was in mapping the subsurface faults and volcanic bodies. Two profiles were selected that cross major anomalies and the geothermal zone of Ixtlan. The Talwani algorithm for 2-D polygonal bodies has been used for calculating the theoretical anomalies. The proposed models adequately explain the main observed geological features. The models are made up of two lithostratigraphic units of volcanic rocks, represented by the Tertiary basalts, which adequately reflect the area's volcanic environment. These basaltic units, corresponding to different volcanic events were cut by the Ixtlan well. Both models reflect the existence of the Ixtlan-Encinal fault, the most important feature in the area which is also responsible for the existence of the geothermal area.

    Objective To prospectively assess the relationship between overweight/obesity and incidence of type 2 diabetes mellitus (T2DM) among Mexicans aged 50+, assessing effects of age, genetic predisposition,education,physical activity,and place of residence. Materials and methods The Mexican Health and Aging Study (MHAS) was used to prospectively follow respondents free of diabetes in 2001 who became diabetic by 2012. Multivariate random effects logistic regression was used to assess covariates effects on the incidence of T2DM. Results Obese or overweight individuals at baseline (2001) were about 3 and 2 times,respectively,significantly more likely to become diabetic by 2012.Genetic predisposition increases the risk of diabetes by about three times compared to those with no family history of diabetes. Conclusion Overweight/obesity and genetic predisposition are the primary drivers of diabetes incidence among Mexican older adults. Reducing body weight and having access to health care may ameliorate the disease burden of T2DM. PMID:26172229

    The aim of this cross-sectional study was to test the accuracy of Cameriere's European formula for age assessment in a large sample of Mexican children. The accuracy of dental age estimation was defined as how closely real age, measured as the difference between chronological age (CA) and dental age (DA), could be predicted. Digitalized orthopantomographs of 502 Mexican children (254 girls and 248 boys), aged between 5 and 15 years, were analyzed. The seven left permanent mandibular teeth were evaluated using Cameriere's method. Intra- and inter-observer variability for this technique was tested on a small random sample. Dental age was estimated for each individual and compared with known chronological age. Accuracy was measured as the difference between known chronological age and dental age and tested for significance with the mean prediction error (ME). The standard deviation and 95% confidence interval of the mean difference were also calculated. ME was 0.63 years for girls and 0.52 years for boys. ME was found to be slightly overestimated by 0.10 years for girls, but was correctly estimated for boys with an accuracy of 0.00. In conclusion, this method is very useful and may be recommended for practical application both in clinical dentistry and forensic procedures on the Mexican population.

    Background Descriptive studies of chiropractic patients are not new, several have been performed in the U.S., Australia, Canada, and Europe. None have been performed in a Latin American country. The purpose of this study is to describe the patients who visited a Mexican chiropractic college public clinic with respect to demographics and clinical characteristics. Methods This study was reviewed and approved by the IRB of Parker College of Chiropractic and the Universidad Estatal del Valle de Ecatepec (UNEVE). Five hundred patient files from the UNEVE public clinic from May 2005 to May 2007 were selected from an approximate total number of 3,700. Information was collected for demographics, chief complaints, associated complaints, and previous care sought. Results The sample comprised 306 (61.2%) female. Most files (44.2%) were in the age range of 40–59 years (mean of 43.4 years). The most frequent complaints were lumbar pain (29.2%) and extremity pain (28.0%), most commonly the knee. Most (62.0%) described their complaints as greater than one year. Trauma (46.6%) was indicated as the initial cause. Mean VAS score was 6.26/10 with 20% rated at 8/10. Conclusion Demographic results compared closer to studies conducted with private clinicians (females within the ages of 40–59). The primary complaint and duration was similar to previous studies (low back pain and chronic), except in this population the cause was usually initiated by trauma. The most striking features were the higher number of extremity complaints and the marked increased level of VAS score (20% rated as 8/10). PMID:19298656

    2002-04-01

    We carried out an integrated paleomagnetic, rock-magnetic and paleointensity study of Miocene volcanic succession from the trans-Mexican volcanic belt (TMVB) north of Guadalajara. A total of 37 consecutive basaltic lava flows (326 oriented standard paleomagnetic cores) were collected at Lazo locality. Continuous susceptibility measurements with temperature and hysteresis experiments yield in most cases reasonably reversible curves with Curie points close to that of pseudo-single-domain magnetite. Two geomagnetic reversals were observed in the 300 m thick composite section. Paleosecular variation was lower than the one observed in general during Miocene. It appears that the volcanic units have been emplaced during a relatively short time span of about 1 Ma. The mean paleomagnetic directions obtained from this study do not differ significantly from that expected for the middle Miocene. The mean paleomagnetic direction calculated from all data is I=31.1°, D=354.6°, k=124 and α95=2.1°, N=37. Seventy-two samples with apparently preserved primary magnetic mineralogy and without secondary magnetization, mostly belonging to reverse polarity chron were pre-selected for Thellier paleointensity determination. The flow-mean paleointensity values are ranging from 22.4±3.4 to 53.8±6.0 μT and the corresponding virtual dipole moments (VDMs) are ranging from (5.4±0.8) to (12.0±1.4)×10 22 A m 2. This corresponds to mean value of (7.7±2.2)×10 22 A m 2, which is close to present day geomagnetic field strength. Altogether, our data suggest the existence of relatively high geomagnetic field strength undergoing low fluctuations.

  16. The North American Free Trade Agreement (NAFTA) and Mexican Nursing

    PubMed Central

    2011-01-01

    In the context of nurse migration, experts view trade agreements as either vehicles for facilitating migration or as contributing to brain-drain phenomena. Using a case study design, this study explored the effects of the North American Free Trade Agreement (NAFTA) on the development of Mexican nursing. Drawing results from a general thematic analysis of 48 interviews with Mexican nurses and 410 primary and secondary sources, findings show that NAFTA changed the relationship between the State and Mexican nursing. The changed relationship improved the infrastructure capable of producing and monitoring nursing human resources in Mexico. It did not lead to the mass migration of Mexican nurses to the United States and Canada. At the same time, the economic instability provoked by the peso crisis of 1995 slowed the implementation of planned advances. Subsequent neoliberal reforms decreased nurses’ security as workers by minimizing access to full-time positions with benefits, and decreased wages. This article discusses the linkages of these events and the effects on Mexican nurses and the development of the profession. The findings have implications for nursing human resources policy-making and trade in services. PMID:20595330

    Escandón, Socorro

    2006-08-01

    This study employed grounded theory to formulate a conceptual model of intergenerational caregiving among Mexican American families. The sample consisted of 10 Mexican American caregivers of various generations older than 21 who provided at least one intermittent service (without pay at least once a month) to an elder, related through consanguinal or acquired kinship ties. The inductively generated theory of role acceptance is composed of four phases: (a) introduction--early caregiving experiences, (b) role reconciliation, (c) role imprint, and (d) providing or projecting care. This model can be used to study varied generations of Mexican American caregivers. It also provides a framework for comparison with other groups of caregivers. The results can help in designing nursing interventions to support caregivers based on understanding the issues, to create and design systems that address the varying and ever-changing needs of informal caregivers, and to assist in the formulation of policy that supports Mexican American caregivers.

  19. Lactobacillus species isolated from vaginal secretions of healthy and bacterial vaginosis-intermediate Mexican women: a prospective study

    PubMed Central

    2013-01-01

    Background Lactobacillus jensenii, L. iners, L. crispatus and L. gasseri are the most frequently occurring lactobacilli in the vagina. However, the native species vary widely according to the studied population. The present study was performed to genetically determine the identity of Lactobacillus strains present in the vaginal discharge of healthy and bacterial vaginosis (BV) intermediate Mexican women. Methods In a prospective study, 31 strains preliminarily identified as Lactobacillus species were isolated from 21 samples collected from 105 non-pregnant Mexican women. The samples were classified into groups according to the Nugent score criteria proposed for detection of BV: normal (N), intermediate (I) and bacterial vaginosis (BV). We examined the isolates using culture-based methods as well as molecular analysis of the V1–V3 regions of the 16S rRNA gene. Enterobacterial repetitive intergenic consensus (ERIC) sequence analysis was performed to reject clones. Results Clinical isolates (25/31) were classified into four groups based on sequencing and analysis of the 16S rRNA gene: L. acidophilus (14/25), L. reuteri (6/25), L. casei (4/25) and L. buchneri (1/25). The remaining six isolates were presumptively identified as Enterococcus species. Within the L. acidophilus group, L. gasseri was the most frequently isolated species, followed by L. jensenii and L. crispatus. L. fermentum, L. rhamnosus and L. brevis were also isolated, and were placed in the L. reuteri, L. casei and L. buchneri groups, respectively. ERIC profile analysis showed intraspecific variability amongst the L. gasseri and L. fermentum species. Conclusions These findings agree with previous studies showing that L. crispatus, L. gasseri and L. jensenii are consistently present in the healthy vaginal ecosystem. Additional species or phylotypes were detected in the vaginal microbiota of the non-pregnant Mexican (Hispanic-mestizo) population, and thus, these results further our understanding of

    The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research. Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design, the specific research questions this approach can help answer, the data sources that tend to be used, and the particular advantages and disadvantages of employing this methodological approach. The paper concludes with key pointers to aid those designing and appraising proposals for conducting case study research, and a checklist to help readers assess the quality of case study reports.

    Major histocompatibility complex (MHC) genes are highly polymorphic and informative in disease association, transplantation, and population genetics studies with particular importance in the understanding of human population diversity and evolution. The aim of this study was to describe the HLA diversity in Mexican admixed individuals. We studied the polymorphism of MHC class I (HLA-A, -B, -C), and class II (HLA-DRB1, -DQB1) genes using high-resolution sequence based typing (SBT) method and we structured the blocks and conserved extended haplotypes (CEHs) in 234 non-related admixed Mexican individuals (468 haplotypes) by a maximum likelihood method. We found that HLA blocks and CEHs are primarily from Amerindian and Caucasian origin, with smaller participation of African and recent Asian ancestry, demonstrating a great diversity of HLA blocks and CEHs in Mexicans from the central area of Mexico. We also analyzed the degree of admixture in this group using short tandem repeats (STRs) and HLA-B that correlated with the frequency of most probable ancestral HLA-C/−B and -DRB1/−DQB1 blocks and CEHs. Our results contribute to the analysis of the diversity and ancestral contribution of HLA class I and HLA class II alleles and haplotypes of Mexican admixed individuals from Mexico City. This work will help as a reference to improve future studies in Mexicans regarding allotransplantation, immune responses and disease associations. PMID:24086347

    Increasing numbers of researchers are finding that loneliness is a significant risk factor for morbidity and mortality, and several variables have been found to be closely related to the experience of loneliness among elders. However, much of the research has focused on the general older population, with no research to date focusing on minority populations. The objective of this study was to determine the prevalence and the correlates of loneliness among a community-dwelling older Mexican American population. This study used a three-item loneliness scale to determine the prevalence of loneliness. Pearson's correlation and linear regression analyses were used to determine the cross-sectional association between sociodemographic, interpersonal relationship and health variables with the scale. Data used came from the most recent wave (2011) of the Hispanic Established Populations for the Epidemiological Study of the Elderly (H-EPESE). A total of 873 Mexican Americans completed the loneliness scale. The age range was from 80 to 102, with a majority (65%) female. The mean score on the scale was 4.05 (range 3-9), indicating relatively low levels of loneliness. Regression results indicate that depressive symptoms, cognitive status, and living alone were significantly associated with higher loneliness scores. Being married and having a confidante were significantly associated with lower loneliness. Age, number of close relatives and frequency of contact were not associated with loneliness. Findings suggest that among community-dwelling Mexican American older adults, loneliness has multiple determinants. Loneliness is a significant public health topic and clinicians should be aware of the various factors that can affect loneliness.

    Mexican immigrants to the U.S. are nearly three times more likely to be without health insurance than non-Hispanic native citizens. To inform strategies to increase the number of insured within this population, we elicited immigrants' understanding of health insurance and preferences for coverage. Nine focus groups with Mexican immigrants were conducted across the State of North Carolina. Qualitative, descriptive methods were used to assess people's understanding of health insurance, identify their perceived need for health insurance, describe perceived barriers to obtaining coverage, and prioritize the components of insurance that immigrants value most. Individuals have a basic understanding of health insurance and perceive it as necessary. Participants most valued insurance that would cover emergencies, make care affordable, and protect family members. Barriers to obtaining insurance included cost, concerns about immigration status discovery, and communication issues. Strategies that address immigrants' preferences for and barriers to insurance should be considered.

  5. Metabolic effects of the contraceptive skin patch and subdermal contraceptive implant in Mexican women: A prospective study

    PubMed Central

    2014-01-01

    Background The contraceptive skin patch (CSP) accepted by the U.S. FDA in 2001 includes ethinylestradiol and norelgestromine, whereas the subdermal contraceptive implant (SCI) has etonogestrel and is also approved by the FDA. In Mexico, both are now widely used for contraception but their effects on Mexican population are unknown. The objective of the study was to evaluate if these treatments induce metabolic changes in a sample of indigenous and mestizo Mexican women. Methods An observational, prospective, longitudinal, non-randomized study of women between 18 and 35 years of age assigned to CSP or SCI. We performed several laboratory tests: clinical chemistry, lipid profile, and liver and thyroid function tests. Also, serum levels of insulin, C-peptide, IGF-1, leptin, adiponectin, and C reactive protein were assayed. Results Sixty-two women were enrolled, 25 used CSP (0 indigenous; 25 mestizos) and 37 used SCI (18 indigenous; 19 mestizos). Clinical symptoms were relatively more frequent in the SCI group. Thirty-four contraceptive users gained weight without other clinical significant changes. After 4 months of treatment, significant changes were found in some biochemical parameters in both treatment groups. Most were clinically irrelevant. Interestingly, the percentage of users with an abnormal atherogenic index diminished from 75% to 41.6% after follow-up. Conclusions The CSP slightly modified the metabolic variables. Most changes were nonsignificant, whereas for SCI users changes were more evident and perhaps beneficial. Results of this attempt to evaluate the effects of contraceptives in mestizo and native-American populations show that clinical symptoms are frequent in Mexican users of CSP and SCI. Although these medications may affect some metabolic variables, these changes seem clinically irrelevant. Induction of abnormalities in other physiological pathways cannot be ruled out.

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

  7. An Integratted Paleomagnetic Study of Rio Grande Santiago Volcanic Succession (Trans Mexican Volcanic Belt): Revisited

    2001-12-01

    We carried out a detailed paleomagnetic, rock-magnetic and paleoinetsnity study of Miocene volcanic succession from the Trans-Mexican Volcanic Belt north of Guadalajara. A total of 37 consecutive basaltic lava flows (326 oriented standard paleomagnetic core) were collected at Lazo locality. Several rock-magnetic experiments were carried out in order to identify the magnetic carriers and to obtain information about their paleomagnetic stability. These experiments combined with microscopy study shows that the main magnetic mineral is Ti-poor titanomagnetite associated with exsoluted ilmenite. Two geomagnetic reversals were observed in the 300m thick composite section. According to the dispersion of virtual geomagnetic pole directions, paleosecular variation was lower than the one observed in general during Miocene. Considering our paleomagnetic results altogether with available radiometric data, it seems that the volcanic units have been emplaced during a relatively short time span of about 1 My. The mean paleomagnetic directions obtained from this study do not differ significantly from that expected for the Middle Miocene. The mean paleomagnetic direction calculated from all data is I = 31.1o, D = 354.6o, k = 124 and a95 = 2.1o, N=37, which corresponds to the mean paleomagnetic pole position Plat=84o, Plong=129.8o, K=29, A95=4.4o. Seventy two samples with apparently preserved primary magnetic mineralogy and without secondary magnetization, mostly belonging to reverse polarity zone were pre-selected for Thellier paleointensity determination. The flow-mean paleointensity values are ranging from 22.4 +/- 3.4 to 53.8 +/- 6.0 mT and the corresponding Virtual Dipole Moments are ranging from 5.4 +/- 0.8 to 12.0 +/- 1.4 (1022 Am2). This correspond to mean value of 7.98 +/- 2.21 x 1022 Am2, which is close to present day geomagnetic field strength. Altogether, our data suggest the existence of relatively high geomagnetic field strength undergoing low fluctuations.

    The objective of this study was to evaluate the differences in allele and genotype frequencies of -383 tumor necrosis factor receptor 1 (TNFR1) polymorphism between ankylosing spondylitis (AS) and controls. Mexican Mestizos with AS were matched by gender, age, and ethnicity with healthy controls and compared in allele and genotype frequencies of the -383 TNFR1 polymorphism. Polymorphisms were genotyped using PCR-RFLP. The AA genotype occurred at a higher frequency in the AS group (92%) compared with controls (79%, P = 0.03). A allele was increased in AS (96% vs. 88%, P = 0.015) and was associated with genetic susceptibility for AS (odds ratio = 3.48, 95% CI = 1.23-10.61). This preliminary study is the first assessing the association of the -383 A/C TNFR1 polymorphism with AS, although it has the limitation of a small sample size. These data are of interest for the genetic epidemiology of AS in the Mexican population, requiring further investigation in other countries.

    The rapid Latino population growth in emerging Latino communities (EmLCs) presents a challenge to health care providers as most current health interventions and health promotion programs intended for Latinas/os are based on characteristics of established Latino communities (EsLCs). This study addresses the gap in the literature by modifying and testing the beginning efficacy of a school-based health intervention for adolescents of Mexican heritage in a rural EmLC. Seventy adolescents of Mexican heritage attending a rural middle school participated in the intervention. Paired samples t-tests were performed to determine differences between healthy behaviors at post-intervention compared to pre-intervention. Significant improvements in participants' physical activity and healthy eating were observed between pre-intervention and post-intervention. A school-based health intervention designed to increase healthy behaviors of adolescents of Mexican heritage in a rural EmLC was successful. PMID:20803071

    Cervical cancer is an important cause of mortality for women in developing countries. Researchers have established a link between cervical cancer and the human papillomavirus (HPV). We explored Mexican women's beliefs about cervical cancer and sexually transmitted infections (STIs), including HPV, to better understand the social implications of this linkage. We conducted eight focus groups with middle-aged and young women in Mexico City. Cervical cancer elicited different social and emotional responses than STIs; participants generally attached less culpability to it and saw it as more life threatening. Information campaigns should take into account differences in lay conceptions of these illnesses.

    The current study examined the longitudinal relations of socio-cultural stressors (i.e., acculturative stressors, enculturative stressors, ethnic discrimination) and Mexican-origin adolescent mothers’ depressive symptoms and risk-taking behaviors. Utilizing an idiographic and nomothetic approach, we conducted lagged analyses to examine how individuals’ fluctuations in stressors predicted subsequent adjustment. Further, we investigated potential threshold effects by examining if the impact of fluctuations in stressors differed at varying levels of stressors. Mexican-origin adolescent females (N = 184) participated in yearly in-home assessments across 5 years and reported on their experiences of acculturative and enculturative stressors, ethnic discrimination, depressive symptoms, and risk-taking behaviors. Findings revealed that within-person fluctuations in acculturative stressors, and to a lesser extent, perceived discrimination, related to youths’ depressive symptoms. For risk-taking behaviors, however, only within-person fluctuations in enculturative stressors emerged as significant. Further, a threshold effect emerged in the link between enculturative stressors and risk-taking behaviors, suggesting that fluctuations in enculturative stressors predicted changes in risk-taking behaviors at high levels of enculturative stressors, but not low levels. Our findings highlight the differential relations between socio-cultural stressors and adolescent females’ adjustment, and suggest that prevention programs aimed at reducing depressive symptoms should attend to any degree of change in socio-cultural stressors, whereas programs focused on risk-taking behaviors should be especially attuned to levels of enculturative stress.

    Although researchers have related sexual desire in older women to quality-of-life variables such as overall physical health, well-being, and life satisfaction, little is known about the socio-cultural mechanisms that shape sexual desire in minority ethnic older women. We investigated this sexual variable among Mexican-American older women in a qualitative fashion. Date were collected from 25 community-dwelling women of Mexican descent (aged 59–89 years) using a semi-structured interview protocol and a grounded theory approach. We inquired about dimensions of sexual desire including sexual fantasies and the desire to engage in sexual activity within the context of several socio-cultural and health-related factors. Using content analysis, we were able to identify key themes differentiating among respondents’ levels of sexual desire and fantasies. These included the availability of a suitable partner, cultural and religious norms pertinent to women’s sexuality, stigma related to sexuality in older age, and health status. Traditional socio-cultural restrictions coupled with unmarried status and physical health problems emerged as critical issues associated with limited or no sexual fantasies and desire in our sample. Many respondents indicated that their sexual needs were unmet. PMID:20526982

    Background In 1996, Mexico started to register cases of childhood cancer. Here, we describe the incidence of cancer in children, residing in ten Mexican jurisdictions, who were treated by the Instituto Mexicano del Seguro Social (IMSS). Methods New cases of childhood cancer, which were registered prospectively in nine principal Medical Centers of IMSS during the periods 1998–2000 (five jurisdictions) and 1996–2002 (five jurisdictions), were analyzed. Personnel were specifically trained to register, capture, and encode information. For each of these jurisdictions, the frequency, average annual age-standardized incidence (AAS) and average annual incidence per period by sex and, age, were calculated (rates per 1,000,000 children/years). Results In total 2,615 new cases of cancer were registered, with the male/female ratio generally >1, but in some tumors there were more cases in females (retinoblastoma, germ cells tumors). The principal groups of neoplasms in seven jurisdictions were leukemias, central nervous system tumors (CNS tumors), and lymphomas, and the combined frequency for these three groups was 62.6 to 77.2%. Most frequently found (five jurisdictions) was the North American-European pattern (leukemias-CNS tumors-lymphomas). Eight jurisdictions had AAS within the range reported in the world literature. The highest incidence was found for children underless than five year of age. In eight jurisdictions, leukemia had high incidence (>50). The AAS of lymphomas was between 1.9 to 28.6. Chiapas and Guerrero had the highest AAS of CNS tumors (31.9 and 30.3, respectively). The frequency and incidence of neuroblastoma was low. Chiapas had the highest incidence of retinoblastoma (21.8). Germ-cell tumors had high incidence. Conclusion The North American-European pattern of cancers was the principal one found; the overall incidence was within the range reported worldwide. In general but particularly in two jurisdictions (Yucatán and Chiapas), it will be necessary

    Efficient reef management strategies rely on detailed knowledge of biological exchange dynamics. At present, available connectivity information on Mexican Atlantic reefs is scarce, particularly concerning the Veracruz Reef System (VRS), which is located in the south-western Gulf of Mexico. This study used a hierarchically nested sampling design to evaluate the levels of genetic connectivity both within and between the Mexican Caribbean (MC) and VRS reef regions; all of the studied reefs are marine protected areas. Microsatellites were used as genetic markers, and bicolor damselfish ( Stegastes partitus) recruits were used as a biological model. The paired genetic differentiation index between regions ( Fst (ENA) = 0.008) was lower than the global index ( Fst (ENA) = 0.027), suggesting that the stronger restrictions to gene flow may be located inside the regions rather than between them. The AMOVA results supported this explanation, as the differences were only non-significant between regions. In the VRS, Santiaguillo reef was associated with low genetic connectivity levels, whilst within the MC region the group formed by Chinchorro Bank and Cozumel exhibited a restriction to gene flow with Puerto Morelos, their northernmost reef. Despite their spatial separation, reefs from different regions (Puerto Morelos and Anegada de Adentro) showed the lowest, albeit significant, genetic difference, meaning that a subtle genetic connectivity exists at the regional scale. The detected composite flow pattern is likely related to self-recruitment and cohesive dispersal processes interacting with current patterns, which may favour genetic connections under specific conditions. The results presented here suggest that coral reef management in the Mexican Atlantic Ocean should consider large scale measures in addition to appropriate local actions to protect reef fish populations.

The first, at Union Electric, serves to test and validate the model and to illustrate its use for demand/supply option evaluation. Focusing on nuclear plant life extension, the Virginia Power case demonstrates the model's extensive detail, particularly in the production cost and financial areas, as well as its flexibility in addressing approximately 70 uncertainty scenarios. Puget Sound Power Light, the third case, used MIDAS for the preparation of its integrated resource plan. A 108-endpoint decision tree illustrates the full power of the decision analysis capability.

    Background: Previous studies suggest that blood lead levels are positively associated with attention deficit/hyperactivity disorder (ADHD) and ADHD-symptoms in children. However, the associations between lead exposure and ADHD subtypes are inconsistent and understudied. Objective: The objective of this study was to explore the association of low-level concurrent lead exposure with subtypes of ADHD symptoms in 578 Mexican children 6–13 years of age. Methods: We measured concurrent blood lead levels using inductively coupled plasma mass spectrometry (ICPMS). We administered the Conners’ Rating Scales-Revised (CRS-R) to mothers to evaluate their children’s ADHD symptoms. We used imputation to fill missing values in blood lead levels and used segmented regression models adjusted for relevant covariates to model the nonlinear relationship between blood lead and ADHD symptoms. Results: Mean ± SD blood lead levels were 3.4 ± 2.9 μg/dL. In adjusted models, a 1-μg/dL increase in blood lead was positively associated with Hyperactivity and Restless-Impulsivity scores on the CRS-R scale and Hyperactivity-Impulsivity scores on the CRS-R scale of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, but only in children with blood lead level ≤ 5 μg/dL. Blood lead was not associated with Inattentive symptoms or overall ADHD behavior. Conclusions: In this population of Mexican children, current blood lead level among children with low exposure (≤ 5 μg/dL) was positively associated with hyperactive/impulsive behaviors, but not with inattentiveness. These results add to the existing evidence of lead-associated neurodevelopmental deficits at low levels of exposure.

    Migration and population movement are increasingly viewed as important factors associated with HIV transmission risk. With growing awareness of the potential impact of migration on HIV transmission, several perspectives have emerged that posit differing dynamics of risk. We considered available data on the role of migration on HIV transmission among Mexican migrants in New York City and Puebla, Mexico.

    Migration and population movement are increasingly viewed as important factors associated with HIV transmission risk. With growing awareness of the potential impact of migration on HIV transmission, several perspectives have emerged that posit differing dynamics of risk. We considered available data on the role of migration on HIV transmission among Mexican migrants in New York City and Puebla, Mexico. Specifically, we examined 3 distinct models of migratory dynamics of HIV transmission—namely, the structural model, the local contextual model, and the interplay model. In doing so, we reframed current public health perspectives on the role of migration on HIV transmission. PMID:24825203

    The objective of this review is to present an overview of some of the most commonly consumed artisanal Mexican cheeses, as well as those cheeses that show potential for a protected designation of origin. A description is given for each of these cheeses, including information on their distinguishing characteristics that makes some of them potential candidates for achieving a protected designation of origin status. This distinction could help to expand their frontiers and allow them to become better known and appreciated in other parts of the world. Due to the scarcity of scientific studies concerning artisanal Mexican cheeses, which would ultimately aid in the standardization of manufacturing processes and in the establishment of regulations related to their production, more than 40 varieties of artisanal cheese are in danger of disappearing. To preserve these cheeses, it is necessary to address this challenge by working jointly with government, artisanal cheesemaking organizations, industry, academics, and commercial partners on the implementation of strategies to protect and preserve their artisanal means of production. With sufficient information, official Mexican regulations could be established that would encompass and regulate the manufacture of Mexican artisanal cheeses. Finally, as many Mexican artisanal cheeses are produced from raw milk, more scientific studies are required to show the role of the lactic acid bacteria and their antagonistic effect on pathogenic microorganisms during aging following cheese making.

    A longitudinal study (15years) investigates heroin use patterns following precocious transition experiences for gang-affiliated Mexican-American males (n=119) in San Antonio, Texas. Five precocious transitions are examined: cohabitation, early nest leaving, school dropout, teenage parenthood, and unemployment (while not in school). Half of these men used heroin over the follow-up period for an average of under 4years. Findings from a zero-inflated Poisson model indicate that while these transitions do not have a significant effect on initiation of heroin use, they do have an important influence on individual's drug trajectories once they have initiated. Early-nest leaving and teenage parenthood are protective factors for continued heroin use while dropping out of high school and cohabiting during this same period are risk factors. Findings are discussed within the context of these disadvantaged and marginalized communities. PMID:27092995

    There is a void in the literature with regard to Hispanic parents' views about common interventions for children with behavior problems. The purpose of this study was to examine the treatment acceptability of child management techniques in a Mexican American sample. Parents' acculturation was also examined to determine if it would account for differences in treatment acceptability. Mexican American parents found response cost, a punishment-based technique, more acceptable than positive reinforcement-based techniques (e.g., differential attention). Results suggest that Mexican American parents' acculturation has little impact on acceptability of child management interventions. No association was found between mothers' acculturation and treatment acceptability. However, more acculturated Mexican American fathers viewed token economy as more acceptable than less acculturated fathers. Results are discussed in the context of clinical work and research with Mexican Americans.

    Aims Alcohol consumption and internalizing symptoms, which often co-occur, pose considerable risk to the developing adolescent and have lasting public health consequences. Previous research has documented concurrent associations between alcohol use and symptoms of anxiety and depression, but the dearth of longitudinal research, particularly for ethnic minority youth, raises questions about the replicability and causal direction of these effects. The goal of the present research was to clarify these issues, and investigate whether different facets of anxiety and depression are uniquely associated with alcohol use in adolescence. Method The present research examined cross-lagged relations between frequency of alcohol use and internalizing symptoms, using data from a longitudinal study of 674 Mexican-origin youth (50% female) assessed at ages 14 and 16. Results Alcohol use at age 14 prospectively predicted increases in overall internalizing symptoms, and overall internalizing symptoms at age 14 prospectively predicted increases in alcohol use. Reciprocal effects were consistently found for the general distress and anxious arousal facets, but not for anhedonic depression and a scale measuring the cognitive aspects of anxiety. Conclusions The findings provide evidence of reciprocal relations between alcohol use and internalizing symptoms, but also highlight the danger of treating all symptoms of anxiety and depression as interchangeable components of a single broad domain. Instead, symptoms common to both anxiety and depressive disorders (e.g., general distress) have the most robust reciprocal relations with alcohol use. Thus, intervention programs aimed at reducing early alcohol use by Mexican-origin youth should target this component of the internalizing domain. PMID:26999352

The mutation was detected by PCR mediated site directed mutagenesis. delta F508 was found in 39% of CF chromosomes, a frequency lower than that reported in Argentina and Spain. The high rate of CF cases who die undiagnosed, the ethnic origin of Mexican populations, and the limited number of cases studied could account for the low frequency of the delta F508 mutation found in this preliminary report.

    Background Cyclotella choctawhatcheeana Prasad 1990 is a small centric diatom found in the plankton of water bodies with a wide range of salt concentrations. This paper describes the morphological features of the valve of C. choctawhatcheeana, from Alchichica lake, a hyposaline lake located in Central Mexico, and provides information about their ecology with respect to water chemistry and distribution in the water column along the annual cycle. Alchichica, and their neighbor lake Atexcac, are the only Mexican water bodies where C. choctawhatcheeana has been registered. Results Morphological differences were found with respect to the original description. The valves of C. choctawhatcheeana from Alchichica exceeded the diameter (5–12 μm) given for the type material (3.0–9.5 μm), and it does not forms or seldom forms short chains (2–3 cells) in contrast of up to 20 cell chains. Other difference was the presence of irregularly distributed small silica granules around the margin of the external view of the valve, meanwhile in Prasad's diagnosis a ring of siliceous granules is present near the valve margin; all other features were within the range of variation of the species. Maximum densities (up to 3877 cells ml-1) of C. choctawhatcheeana were found in Alchichica lake from June to October, along the stratificated period of the lake. Low densities (48 cells ml-1) when the water column was mixed, in January and February. C. choctawhatcheeana of Lake Alchichica was found in an ample depth range from 20 m down to 50 m. Conductivity (K25) ranged between 13.3 and 14.5 mS cm-1 and the pH between 8.8 and 10.0. Water temperature fluctuated between 14.5 and 20°C. Dissolved oxygen ranged from anoxic (non detectable) up to saturation (7 mg l-1). Conclusion The morphology of C. choctawhatcheeana from Alchichica corresponded to the original description, with exception of some secondary traits. C. choctawhatcheeana can grow in several different environmental conditions. It

    2014-01-01

    Men are poorly integrated into sexual and reproductive health programmes, despite long-standing calls for their inclusion. From the 1994 Cairo International Conference on Population and Development (ICPD) to the Policy Recommendations for the ICPD Beyond 2014, calls for 'rights for all' conflict with implicit, homogenising framing of men as patriarchal roadblocks to women's empowerment. This framing generates ambivalence about providing men's services, leading to emphasis on 'men as partners' supporting women's autonomous reproductive health decision-making rather than attention to both sexes' health needs. We argue that this framing also belies both the global rise of self-consciously non-traditional masculinities, and the fact that people's ostensibly individual sexual and reproductive health practices are profoundly relational. Here, we reimagine the concept of 'partnering' as an analytic for understanding how lived relationships influence both men's and women's sexual and reproductive practice. 'Partnering' in this sense is the context-dependent collaboration through which a range of gendered actors, not limited to male-female dyads, interact to shape health behaviour. We apply this approach to Mexican men's participation in a medical research on human papillomavirus transmission, demonstrating how spouses jointly refashioned male-focused health surveillance into familial health care and a forum for promoting progressive gender norms to their children and the broader society.

    This research evaluates the properties of a measure of culturally linked values of Mexican Americans in early adolescence and adulthood. The items measure were derived from qualitative data provided by focus groups in which Mexican Americans’ (adolescents, mothers and fathers) perceptions of key values were discussed. The focus groups and a preliminary item refinement resulted in the fifty-item Mexican American Cultural Values Scales (identical for adolescents and adults) that includes nine value subscales. Analyses of data from two large previously published studies sampling Mexican American adolescents, mothers, and fathers provided evidence of the expected two correlated higher order factor structures, reliability, and construct validity of the subscales of the Mexican American Cultural Values Scales as indicators of values that are frequently associated with Mexican/Mexican American culture. The utility of this measure for use in longitudinal research, and in resolving some important theoretical questions regarding dual cultural adaptation, are discussed. PMID:20644653

    Twenty seven obsessive-compulsive disorder (OCD) patients were studied at the Instituto Mexicano de Psiquiatría in Mexico City. This is the first sample of OCD patients studied in Latin America. There was a significant sex ratio difference and a significant difference in the type of obsessions and compulsions displayed by males and females. Co-morbidity data demonstrated a high frequency of obsessive-compulsive personality disorders, depression, sexual abuse, suicidal attempts and neurological damage. Approximately one third of OCD cases demonstrated a positive family history. There was a higher than expected frequency of first degree relatives affected with OCD. In addition, this study may support the hypothesis that OCD and tics are genetically related.

    Objectives. This study examined the association between health insurance coverage, medical care use, limitations in activities of daily living, and mortality among older Mexican-origin individuals. Methods. We analyzed longitudinal data from the Hispanic Established Populations for Epidemiologic Study of the Elderly (H-EPESE). Results. The uninsured tend to be younger, female, poor, and foreign born. They report fewer health care visits, are less likely to have a usual source of care, and more often receive care in Mexico. Conversely, those with private health insurance are economically better off and use more health care services. Over time, the data reveal substantial changes in type of insurance coverage. Conclusions. The data reveal serious vulnerabilities among older Mexican Americans that result from a lack of private Medigap supplemental coverage.

    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.

    Insertion-deletions for human identification purposes (HID-Indels) offer advantages to solve particular forensic situations and complex paternity cases. In Mexico, admixed population known as Mestizos is the largest (∼90%), plus a number of Amerindian groups (∼10%), which have not been studied with HID-Indels. For this reason, allele frequencies and forensic parameters for 38 HID-Indels were estimated in 531 unrelated individuals from one Amerindian (Purépecha) and seven Mestizo populations from different regions of the country. Genotype distribution was in agreement with Hardy-Weinberg expectations in almost all loci/populations. The linkage disequilibrium (LD) test did not reveal possible associations between loci pairs in all eight Mexican populations. The combined power of discrimination was high in all populations (PD >99.99999999998%). However, the power of exclusion of the 38 HID-Indel system (PE >99.6863%) was reduced regarding most of autosomal STR kits. The assessment of genetic structure (AMOVA) and relationships between populations (FST) demonstrated significant differences among Mexican populations, mainly of the Purépecha Amerindian group. Among Mexican-Mestizos, three population clusters consistent with geography were defined: (i) North-West region: Chihuahua, Sinaloa, and Jalisco; (ii) Central-Southern region: Mexico City, Veracruz and Yucatan; (iii) South region: Chiapas. In brief, this report validates the inclusion of the 38 HID-Indel system in forensic casework and paternity cases in seven Mexican-Mestizo populations from different regions, and in one Mexican Amerindian group.

    2013-01-01

    Background Several studies in type 2 diabetes patients have shown significant associations between the SOD2 gene Val16Ala polymorphism and albuminuria, but this association has not been explored in the Mexican population. Methods We evaluated the association between the SOD2 gene Val16Ala polymorphism (rs4880) and macroalbuminuria in a sample of 994 unrelated Mexican type 2 diabetes patients. The study included 119 subjects with urinary albumin >300 mg/dL and 875 subjects with urinary albumin ≤ 30 mg/dL. Genotyping of the SOD2 gene Val16Ala SNP was carried out with Real-Time Polymerase Chain Reaction (RT-PCR). Results The frequency of the TT genotype was 6.7% higher in participants with macroalbuminuria than in the normoalbuminuria group (16.8% vs. 10.1%). Using a logistic regression analysis, we observed that individuals with the CC genotype had significantly lower risks of macroalbuminuria than those with the TT genotype (OR=0.42, p=0.034). We carried out a meta-analysis combining our data with data from four previous studies and estimated an odds ratio (95% CI) for the C allele (with respect to the reference T allele) of 0.65 (0.52-0.80, p<0.001). Conclusions A significant association was found between the SOD2 Val16Ala polymorphism and macroalbuminuria in a sample of Mexican type 2 diabetes patients. PMID:24119114

    Little is known about effects of acculturation on disease risk in young Mexican and Mexican-American women living in a border community. The purpose of this study was to examine relationships between acculturation and features of metabolic syndrome (MetS) in Mexican and Mexican-American women (n = 60) living in the largest US-Mexico border community. Acculturation was measured by the short acculturation scale for Hispanics and birthplace. Body composition was measured by Bod Pod and daily physical activity was measured by questionnaire and accelerometer. Increased acculturation was related to individual features of MetS and increased risk of MetS. These relationships were mediated by fat mass rather than inactivity. Fat mass mediates the relationships between acculturation and individual features of MetS in young Mexican and Mexican-American women. These findings suggest that fat mass, rather than inactivity, is an important contributor to disease risk in young Mexican and Mexican-American women living in a large US/Mexico border community.

  8. Food deserts or food swamps?: A mixed-methods study of local food environments in a Mexican city.

    PubMed

    2015-10-01

    Differential access to healthy foods has been hypothesized to contribute to disparities in eating behaviors and health outcomes. While food deserts have been researched extensively in developed Anglophone countries, evidence from low- and middle-income countries is still scarce. In Mexico, prevalence of obesity is among the highest worldwide. As obesity has increased nationally and become a widespread public health issue, it is becoming concentrated in the low-income population. This mixed-methods study uses a multidimensional approach to analyze food environments in a low-, middle-, and high-income community in a Mexican city. The study advances understanding of the role that food environments may play in shaping eating patterns by analyzing the density and proximity of food outlet types as well as the variety, quantity, quality, pricing, and promotion of different foods. These measures are combined with in-depth qualitative research with families in the communities, including photo elicitation, to assess perceptions of food access. The central aims of the research were to evaluate physical and economic access and exposure to healthy and unhealthy foods in communities of differing socioeconomic status as well as participants' subjective perceptions of such access and exposure. The findings suggest a need to reach beyond a narrow focus on food store types and the distance from residence to grocery stores when analyzing food access. Results show that excessive access and exposure to unhealthy foods and drinks, or "food swamps," may be a greater concern than food deserts for obesity-prevention policy in Mexico.

    This article examines the case of a Mexican American woman who was found not guilty by reason of insanity for infanticide, the murder of her young son. A detailed case history is presented with a focus on cultural issues as they affect this woman's family dynamics, assimilation and acculturation, emotionality, spirituality, and seeking of mental health treatment. In addition, a theoretical conceptualization is presented, identifying the psychodynamic operations that laid the foundation for the crime, including the normal process of identity development and the mitigating factors of gender, culture, and psychopathology. The study explores the important influences of culture in the commission of this crime as well as in subsequent treatment, highlighting the changes in society and mental health treatment that need to be made to reduce the incidence of such family violence.

    Mexican psychiatry initiated since pre-Hispanic times. Historically, treatments were a mixture of magic, science and religion. Ancient Nahuas had their own medical concepts with a holistic view of medicine, considering men and cosmos as a whole. The first psychiatric hospital appeared in 1566 and a more modern psychiatric asylum emerged until 1910. International exchanges of theoretical approaches started in the National University with the visit of Pierre Janet. There were other important figures that influenced Mexican psychiatry, such as Erich Fromm, Henri Ey, Jean Garrabé and Yves Thoret. Regarding Mexican psychiatrists, some of the most important contributors to Mexican psychiatry were José Luis Patiño Rojas, Manuel Guevara Oropeza and Ramón de la Fuente Muñiz. This article includes excerpts from "Clinical Psychiatry", a book by Patiño Rojas where he tries to understand and describe the inner world experienced by patients with schizophrenia; also, the thesis conducted by Guevara Oropeza ("Psychoanalisis"), which is a critical comparison between the theories of Janet and Freud. Finally, we include "The study of consciousness: current status" by Ramón de la Fuente, which leads us through the initial investigations concerning consciousness, its evolution, and the contributions made by psychology, philosophy and neurobiology.

    The hypothesis that endemic species could have originated by the isolation and divergence of peripheral populations of widespread species can be tested through the use of ecological niche models (ENMs) and statistical phylogeography. The joint use of these tools provides complementary perspectives on historical dynamics and allows testing hypotheses regarding the origin of endemic taxa. We used this approach to infer the historical processes that have influenced the origin of a species endemic to the Mexican Plateau (Cynomys mexicanus) and its divergence from a widespread ancestor (Cynomys ludovicianus), and to test whether this endemic species originated through peripatric speciation. We obtained genetic data for 295 individuals for two species of black-tailed prairie dogs (C. ludovicianus and C. mexicanus). Genetic data consisted of mitochondrial DNA sequences (cytochrome b and control region), and 10 nuclear microsatellite loci. We estimated dates of divergence between species and between lineages within each species and performed ecological niche modelling (Present, Last Glacial Maximum and Last Interglacial) to determine changes in the distribution range of both species during the Pleistocene. Finally, we used Bayesian inference methods (DIYABC) to test different hypotheses regarding the divergence and demographic history of these species. Data supported the hypothesis of the origin of C. mexicanus from a peripheral population isolated during the Pleistocene [∼230,000 years ago (0.1-0.43 Ma 95% HPD)], with a Pleistocene-Holocene (∼9,000-11,000 years ago) population expansion (∼10-fold increase in population size). We identified the presence of two possible refugia in the southern area of the distribution range of C. ludovicianus and another, consistent with the distribution range of C. mexicanus. Our analyses suggest that Pleistocene climate change had a strong impact in the distribution of these species, promoting peripatric speciation for the origin of

    Objective Type 2 diabetes (T2DM) is a complex metabolic disease and is more prevalent in certain ethnic groups such as the Mexican Americans. The goal of our study was to perform a genome-wide linkage analysis to localize T2DM susceptibility loci in Mexican Americans. Methods We used the phenotypic and genotypic data from 1,122 Mexican American individuals (307 families) who participated in the Veterans Administration Genetic Epidemiology Study (VAGES). Genome-wide linkage analysis was performed, using the variance components approach. Data from two additional Mexican American family studies, the San Antonio Family Heart Study (SAFHS) and the San Antonio Family Diabetes/Gallbladder Study (SAFDGS), were combined with the VAGES data to test for improved linkage evidence. Results After adjusting for covariate effects, T2DM was found to be under significant genetic influences (h2 = 0.62, P = 2.7 × 10−6). The strongest evidence for linkage of T2DM occurred between markers D9S1871 and D9S2169 on chromosome 9p24.2-p24.1 (LOD = 1.8). Given that we previously reported suggestive evidence for linkage of T2DM at this region in SAFDGS also, we found the significant and increased linkage evidence (LOD = 4.3, empirical P = 1.0 × 10−5, genome-wide P = 1.6 × 10−3) for T2DM at the same chromosomal region when we performed genome-wide linkage analysis of the VAGES data combined with SAFHS and SAFDGS data. Conclusion Significant T2DM linkage evidence was found on chromosome 9p24 in Mexican Americans. Importantly, the chromosomal region of interest in this study overlaps with several recent genome-wide association studies (GWASs) involving T2DM related traits. Given its overlap with such findings and our own initial T2DM association findings in the 9p24 chromosomal region, high throughput sequencing of the linked chromosomal region could identify the potential causal T2DM genes.

    Vasomotor symptoms are one of the main reasons for climateric women to consult a physician. Hormone therapy is the first treatment choice, but it is not indicated to all patients. Veralipride is an option for those who cannot or will not try hormone treatment. The Mexican Association for the Study of Climateric (AMEC) assembled an interdisciplinary group of medical experts so that they revised the medical literature on the subject and reached a consensus on veralipride indication, doses, counterindications and safety. The recommendations of the consensus conference on veralipride are: (1) Physicians must be familiar with its indication, side effects, pharmacokinetics and dosage. (2) Patients must be informed on other therapeutical options. (3) Patients' mental and neurological state must be evaluated, in particular to identify movement disorders, extrapyramidal symptoms (tremor or dystonia), anxiety and depression that can be mistaken for climateric symptoms. (4) Any adverse effect associated with the drug must be reported. (5) A random multicenter trial must be carried out in order to identify the frequency and severity of side effects, and (6) Written information on possible health risks when using the drug must be provided.

    We examined the relation between low self-esteem and depression using longitudinal data from a sample of 674 Mexican-origin early adolescents who were assessed at age 10 and 12 years. Results supported the vulnerability model, which states that low self-esteem is a prospective risk factor for depression. Moreover, results suggested that the vulnerability effect of low self-esteem is driven, for the most part, by general evaluations of worth (i.e., global self-esteem), rather than by domain-specific evaluations of academic competence, physical appearance, and competence in peer relationships. The only domain-specific self-evaluation that showed a prospective effect on depression was honesty–trustworthiness. The vulnerability effect of low self-esteem held for male and female adolescents, for adolescents born in the United States vs. Mexico, and across different levels of pubertal status. Finally, the vulnerability effect held when we controlled for several theoretically relevant third variables (i.e., social support, maternal depression, stressful events, and relational victimization), and for interactive effects between self-esteem and the third variables. The present study contributes to an emerging understanding of the link between self-esteem and depression and provides much needed data on the antecedents of depression in ethnic minority populations.

    1995-06-01

    This paper discusses the influence that "beliefs concerning the corrective effects of punishment" have on child punishment and abuse in a Mexican population. One hundred and five mothers responded to a questionnaire measuring these beliefs, and their responses were contrasted with the report those mothers gave regarding the physical punishment they inflict upon their children. A scale consisting of six items registering beliefs was developed and administered. The reliability (internal consistency) of the scale was assessed, and its validity was tested by using a factor analytic structural equations model which produced high factorial loadings from a "beliefs" factor to the scale's items. This was interpreted as a confirmation of construct validity. An indication of predictive validity was found in a high, significant structural correlation between the beliefs factor and a "corrective punishment" factor, measured by a series of related items. Mothers reported as abusing their children produced higher scores on the "beliefs" scale as compared to "control" mothers. The direct, significant effect of parent's beliefs on the punishment of children explains much about the child maltreatment problem in the studied society.

    This mixed methods case study describes an innovative two-semester middle school environmental learning course that departs from traditional Mexican expository pedagogy through the incorporation of experiential and service learning. This research takes place in a small middle school in Pescadero, Baja California Sur, Mexico. The research approach utilized in the study adds to the handful of studies in this cross-disciplinary field by employing quantitative methodologies to measure course outcomes on student environmental knowledge, perceptions, and actions, while simultaneously qualitatively describing the behavioral, educational, environmental, and social experiences of students. This research employs Dewey's theories of experience---as well as those of more contemporary authenticity theorists---in order to identify the philosophies that advocate incorporating experiential pedagogy within the curriculum. Implications for Mexican educational policy, practical pedagogical applications, and theory are discussed.

    In November 2001, Nature published a letter in which University of California Berkeley's biologists claimed to have found evidence of genetically modified (GM) DNA in regional varieties of maize in Oaxaca, even though the Mexican government had banned transgenic corn agriculture in 1998. While urban protesters marched against the genetic 'contamination' of Mexican corn by US-based agricultural biotech firms, rural indigenous communities needed a framework for understanding concepts such as GM before they could take action. This article analyzes how the indigenous organization, the Zapatistas, mobilized a program to address this novel entity. Their anti-GM project entailed educating local farmers about genetics, importing genetic testing kits, seed-banking landrace corn and sending seeds to 'solidarity growers' around the world. This article explores material-semiotic translations to explain one of the central aspects of this project, the definition and circulation of Zapatista corn--an entity defined not only through cultural geography, but also technological means. Through its circulation, Zapatista corn serves to perform a biocultural engagement with Zapatista's political project of resistance to neoliberalism. While much has been written about both regulatory policy and consumer activism against GM in the Global North, Zapatista corn also provides a case study in indigenous, anti-GM activism founded on biocultural innovation and the creation of alternative networks for circulating corn.

    How racial barriers play in the experiences of Mexican Americans has been hotly debated. Some consider Mexican Americans similar to European Americans of a century ago that arrived in the United States with modest backgrounds but were eventually able to participate fully in society. In contrast, others argue that Mexican Americans have been racialized throughout U.S. history and this limits their participation in society. The evidence of persistent educational disadvantages across generations and frequent reports of discrimination and stereotyping support the racialization argument. In this paper, we explore the ways in which race plays a role in the lives of Mexican Americans by examining how education, racial characteristics, social interactions, relate to racial outcomes. We use the Mexican American Study Project, a unique data set based on a 1965 survey of Mexican Americans in Los Angeles and San Antonio combined with surveys of the same respondents and their adult children in 2000, thereby creating a longitudinal and intergenerational data set. First, we found that darker Mexican Americans, therefore appearing more stereotypically Mexican, report more experiences of discrimination. Second, darker men report much more discrimination than lighter men and than women overall. Third, more educated Mexican Americans experience more stereotyping and discrimination than their less-educated counterparts, which is partly due to their greater contact with Whites. Lastly, having greater contact with Whites leads to experiencing more stereotyping and discrimination. Our results are indicative of the ways in which Mexican Americans are racialized in the United States.

    The Trans-Mexican Volcanic Belt (TMVB) is one of the largest continental volcanic arcs of the North American plate. It spans about 1000 km from the Pacific to the Gulf of Mexico. Despite the abundance of thick lava sequences with quite high extrusion rates, the TMVB have been relatively little studied from a paleomagnetic point of view. Previous studies were aimed for tectonic evolution of the region rather than documenting fluctuations of Earth's magnetic field in terms of both directions and intensity. We report a detailed paleomagnetic and rock-magnetic study of Tequila and Ceboruco-San Pedro-Amado Nervo volcanic fields. 350 oriented samples belonging to 31 independent cooling units were collected. All these sites were previously dated by means of the state-of-the-art 40Ar-39Ar geochronological method and span from 1.1 Ma to 2 Ky. Rock-magnetic experiments which included continuous susceptibility, isothermal remanence acquisition and hysteresis measurements point to simple magnetic mineralogy. In most of cases, the remanence is carried by Ti-poor titanomagnetite of pseudo-single-domain magnetic structure. The paleodirections of the flow dated as 819±25 ka correspond to a VGP latitude of 18° N. This anomalous field behaviour apparently recorded prior to the Matuyama-Brunhes reversal may coincide with the geomagnetic event, defined as M-B precursor. Two independent lava flows, dated as 623±91 and 614±16 ka respectively, yield reverse paleodirections and one lava flow dated as 690±29 yields transitional paleodirections. It is possible that these lavas erupted during the worldwide observable Big Lost or Delta events.

    Generation of solid waste is a problem of great environmental significance in the Mexican Federal District. With an estimated daily generation of 12 500 tons, waste management is a priority for the district government. Integrated waste management programmes have been implemented in the Mexican Federal District in the past. They have failed. This research has examined the most recent initiative in an effort to discover the causes of failure, using a case study approach. In addition to identifying barriers to and opportunities for implementation of an effective integrated waste management system in the Federal District, this research recommends options for a newly proposed waste management system with the aim of achieving the objectives desired by the government, while aiding in the pursuit of sustainable development.

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed. PMID:26583444

    2013-12-01

    In this case study, I use an ethnographic-style approach to understand the funds of knowledge of immigrant families living in colonias on both sides of the US/Mexico border. I focus on how these "knowledges" and concomitant experiences impact the ways we perceive and treat immigrant students who have all too often been viewed through deficit lenses that relegate them to the lowest expectations and outcomes in the classroom. I find that Mexican and Mexican-American families hold unusually sophisticated and relevant "knowledges" to mitigate their everyday lives. In this paper, I will refer to citizens of Mexico, whether they reside in Mexico or have crossed to the United States legally or without documentation for purposes of work, as Mexican. People who have crossed the border and are living in the US as legal residents or have gained citizenship are referred to as Mexican-Americans. They live a hybrid identity that is varied and dynamic, an issue that adds to the complexity of the content and contexts of this study. These families know and use these "knowledges" on a daily basis, yet they are not recognized by teachers in the US as a starting point to affirm and support immigrant children. Instead, immigrant children are relegated to the non-gifted and lower track classes where science is taught from an abstract and non-contextual and therefore less engaged basis. The approach I outline here, based on insights from my case study, can greatly improve teachers' abilities to prepare their curricula for diversity in science education and science literacy as well as for broad expectations for student success.

  12. Evaluation of inflammation-related genes polymorphisms in Mexican with Alzheimer’s disease: a pilot study

    Amyloid peptide is able to promote the activation of microglia and astrocytes in Alzheimer’s disease (AD), and this stimulates the production of pro-inflammatory cytokines. Inflammation contributes to the process of neurodegeneration and therefore is a key factor in the development of AD. Some of the most important proteins involved in AD inflammation are: clusterin (CLU), complement receptor 1 (CR1), C reactive protein (CRP), tumor necrosis factor α (TNF-α), the interleukins 1α (IL-1α), 6 (IL-6), 10 (IL-10) and cyclooxygenase 2 (COX-2). In particular, COX-2 is encoded by the prostaglandin-endoperoxide synthase 2 gene (PTGS2). Since variations in the genes that encode these proteins may modify gene expression or function, it is important to investigate whether these variations may change the developing AD. The aim of this study was to determine whether the presence of polymorphisms in the genes encoding the aforementioned proteins is associated in Mexican patients with AD. Fourteen polymorphisms were genotyped in 96 subjects with AD and 100 controls; the differences in allele, genotype and haplotype frequencies were analyzed. Additionally, an ancestry analysis was conducted to exclude differences in genetic ancestry among groups as a confounding factor in the study. Significant differences in frequencies between AD and controls were found for the single-nucleotide polymorphism (SNP) rs20417 within the PTGS2 gene. Ancestry analysis revealed no significant differences in the ancestry of the compared groups, and the association was significant even after adjustment for ancestry and correction for multiple testing, which strengthens the validity of the results. We conclude that this polymorphism plays an important role in the development of the AD pathology and further studies are required, including their proteins. PMID:26041990

    Roberts, Robert E; Roberts, Catherine Ramsay; Xing, Yun

    2007-02-01

    A reexamination of ethnicity as a risk factor for adolescent suicidal behavior, focusing on whether Mexican American youths are at increased risk, was undertaken. Data from a sample of 4,175 African, European, and Mexican Americans, aged 11-17, are presented. We examined lifetime attempts and past year attempts, thoughts, and plans. Odds ratios, adjusting for covariates, indicate no differences between European and Mexican Americans on past year thoughts, plans, or attempts or lifetime attempts. Although some studies have reported Mexican American youths are at increased risk, we did not find any differences. Possible explanations for disparate results across studies are discussed, in particular methods effects. PMID:17397276

    2007-10-01

    Women of Mexican descent living in the United States raise children who use health care services. What do immigrant Mexican mothers expect from children's health care services? And how do their expectations for children's health services compare to acculturated Mexican American mothers' expectations? This focused ethnographic study, based on repeated interviews with 28 mothers of varying acculturation levels, describes their expectations and experiences with children's health care services in the United States. Findings support a shared core of expectations for both Mexican immigrant and Mexican American mothers, and differences in health care access and financing, time spent in health care encounters, and cultural and linguistic expectations for care. Health care providers can use this information to approach Mexican-descent mothers and children with their expectations in mind, and craft a negotiated plan of care congruent with their expectations.

    Background Several studies have identified multiple obesity-associated loci mainly in European populations. However, their contribution to obesity in other ethnicities such as Mexicans is largely unknown. The aim of this study was to examine 26 obesity-associated single-nucleotide polymorphisms (SNP) in a sample of Mexican mestizos. Methods 9 SNPs in biological candidate genes showing replications (PPARG, ADRB3, ADRB2, LEPR, GNB3, UCP3, ADIPOQ, UCP2, and NR3C1), and 17 SNPs in or near genes associated with obesity in first, second and third wave GWAS (INSIG2, FTO, MC4R, TMEM18, FAIM2/BCDIN3, BDNF, SH2B1, GNPDA2, NEGR1, KCTD15, SEC16B/RASAL2, NPC1, SFRF10/ETV5, MAF, PRL, MTCH2, and PTER) were genotyped in 1,156 unrelated Mexican-Mestizos including 683 cases (441 obese class I/II and 242 obese class III) and 473 normal-weight controls. In a second stage we selected 12 of the SNPs showing nominal associations with obesity, to seek associations with quantitative obesity-related traits in 3 cohorts including 1,218 Mexican Mestizo children, 945 Mexican Mestizo adults, and 543 Indigenous Mexican adults. Results After adjusting for age, sex and admixture, significant associations with obesity were found for 6 genes in the case-control study (ADIPOQ, FTO, TMEM18, INSIG2, FAIM2/BCDIN3 and BDNF). In addition, SH2B1 was associated only with class I/II obesity and MC4R only with class III obesity. SNPs located at or near FAIM2/BCDIN3, TMEM18, INSIG2, GNPDA2 and SEC16B/RASAL2 were significantly associated with BMI and/or WC in the combined analysis of Mexican-mestizo children and adults, and FTO locus was significantly associated with increased BMI in Indigenous Mexican populations. Conclusions Our findings replicate the association of 8 obesity-related SNPs with obesity risk in Mexican adults, and confirm the role of some of these SNPs in BMI in Mexican adults and children.

    Background: Diverse variables are implicated in the pathogenesis of gingival recession; more detailed knowledge about the relationship between the clinical presentation of gingival recession and assorted risk indicators may lead to improved patient monitoring, early intervention, and subsequent prevention. The objective was to evaluate clinically gingival recession in a homogeneous Mexican adult male population and to determine the strength of association with related factors. Method: A cross-sectional study was carried out in a largely homogeneous group in terms of ethnic background, socioeconomic status, gender, occupation, and medical/dental insurance, in Campeche, Mexico. Periodontal examinations were undertaken to determine diverse clinical dental variables. All periodontal clinical examinations were assessed using the Florida Probe System, a dental chair and one examiner. Questionnaires were used to collect diverse risk indicators. Statistical analyses were undertaken with negative binomial regression models. Results: The mean number of sites with gingival recession per subject was 6.73±5.81; the prevalence was 87.6%. In the negative binomial regression model we observed that for (i) each year of age, and (ii) each percentage unit of increase in sites with plaque, and (iii) with suppuration, mean sites with gingival recession increased 2.9%, 1.0% and 13.0%, respectively. Having a spouse was associated with gingival recession. Conclusions: We observed association between gingival recession, and sociodemographic and clinical parameters. Patients need to be educated about risk indicators for gingival recession as well as the preventive maneuvers that may be implemented to minimize its occurrence. The potential of improved oral self-care to prevent a largely benign condition such as gingival recession is important, given the associated disorders that may ensue root exposure, such as root caries and root hypersensitivity.

    OBJECTIVE. To identify studies on quality of health care in the IMSS. MATERIALS AND METHODS. A bibliometric, descriptive cross-sectional and retrospective study was conducted, from 1992 to 2011. RESULTS. We identified 881 research studies related to the issue of quality (CI95% 10.6-12.0) of 7 762 studies presented at the annual research meetings. 10 521 articles were published in this period of time and only 946 (CI95% 8.4-9.5) were linked to the issue of quality. CONCLUSIONS. The results of this study allowed us to identify the interest about research on quality. Further research is needed to establish what has been the impact on the improvement of quality in health care.

    Objective. Assessment of the frequency of complications observed with various forceps and operative vaginal delivery (OVD) techniques performed at the ABC Medical Center (Mexico City) to evaluate their safety, bearing in mind the importance of decreasing our country's high cesarean section incidence. Methods. We reviewed 5,375 deliveries performed between the years 2007 and 2012, only 146 were delivered by OVD.  Results. Only 1.0% of the cases had a serious, life-threatening situation (uterine rupture). The Simpson forceps was the most favored instrument (46%) due to its simplicity of use, effectiveness, and familiarity. Prophylactic use was the most common indication (30.8%) and significant complications observed were vaginal lacerations (p = 0.016), relative risk (RR) of 3.4 (95% confidence interval [CI]: 1.15–10.04), and fourth degree perineal tear (p = 0.016), RR of 3.4 (95% CI: 1.15–10.04). Conclusions. Forceps use and other OVD techniques are a safe alternative to be considered, diminishing C-section incidence and its complications. PMID:26380111

    It is calculated that distal deletion of the short arm of chromosome 1 occurs in one out of every 5000 live births and causes approximately 1.2% of cases of mental retardation of unknown origin. This alteration usually cannot be detected in the standard karyotype, requiring molecular cytogenetic techniques for the diagnosis. In addition to the neurological manifestations, it may cause internal organs malformations, such as congenital heart disease, and a characteristic facial phenotype. This report describes the clinical and cytogenetic findings from the first two cases diagnosed in Mexico, confirmed by fluorescence in situ hybridization test, and compares them to those described in the literature. The probable subdiagnosis of this entity, the importance of improves its recognition and the useful data for the clinical suspicion are also discussed.

    Mexico has one of the highest incidences of childhood leukemia worldwide and significantly higher mortality rates for this disease compared with other countries. One possible cause is the high prevalence of gene rearrangements associated with the etiology or with a poor prognosis of childhood acute lymphoblastic leukemia (ALL). The aims of this multicenter study were to determine the prevalence of the four most common gene rearrangements [ETV6-RUNX1, TCF3-PBX1, BCR-ABL1, and MLL rearrangements] and to explore their relationship with mortality rates during the first year of treatment in ALL children from Mexico City. Patients were recruited from eight public hospitals during 2010-2012. A total of 282 bone marrow samples were obtained at each child's diagnosis for screening by conventional and multiplex reverse transcription polymerase chain reaction to determine the gene rearrangements. Gene rearrangements were detected in 50 (17.7%) patients. ETV6-RUNX1 was detected in 21 (7.4%) patients, TCF3-PBX1 in 20 (7.1%) patients, BCR-ABL1 in 5 (1.8%) patients, and MLL rearrangements in 4 (1.4%) patients. The earliest deaths occurred at months 1, 2, and 3 after diagnosis in patients with MLL, ETV6-RUNX1, and BCR-ABL1 gene rearrangements, respectively. Gene rearrangements could be related to the aggressiveness of leukemia observed in Mexican children.

    2010-01-01

    This review presents a detailed analysis of the state of knowledge of studies done in Mexico related to the dinoflagellate Gymnodinium catenatum, a paralytic toxin producer. This species was first reported in the Gulf of California in 1939; since then most studies in Mexico have focused on local blooms and seasonal variations. G. catenatum is most abundant during March and April, usually associated with water temperatures between 18 and 25 °C and an increase in nutrients. In vitro studies of G. catenatum strains from different bays along the Pacific coast of Mexico show that this species can grow in wide ranges of salinities, temperatures, and N:P ratios. Latitudinal differences are observed in the toxicity and toxin profile, but the presence of dcSTX, dcGTX2-3, C1, and C2 are usual components. A common characteristic of the toxin profile found in shellfish, when G. catenatum is present in the coastal environment, is the detection of dcGTX2-3, dcSTX, C1, and C2. Few bioassay studies have reported effects in mollusks and lethal effects in mice, and shrimp; however no adverse effects have been observed in the copepod Acartia clausi. Interestingly, genetic sequencing of D1-D2 LSU rDNA revealed that it differs only in one base pair, compared with strains from other regions. PMID:20631876

    Objective Although previous studies have examined the impact of maternal depression on child overweight and obesity, little is known about the relationship in Latino families, who suffer from high risks of depression and obesity. We prospectively investigated the association between depressive symptoms in women with young children and child overweight and obesity (overweight/obesity) at age 7 years among Latino families. Methods Participants included 332 singletons with anthropometric measures obtained at 7 years from the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) study, a birth cohort study. Maternal depression was assessed using the Center for Epidemiologic Studies-Depression (CES-D) scale when the children were 1, 3.5, and 7 years. Overweight and obesity was measured by body mass index (kg/m(2)) at age 7 years. Results 63 % of women had CES-D scores consistent with depression in at least one of the 3 given assessments. Compared to children whose mothers were never depressed, children whose mothers were depressed at all three assessments had 2.4 times the adjusted odds of overweight/obesity at age 7 years (95 % CI 1.1-5.6). However, a single positive maternal depression screen was not associated with child overweight/obesity and there was no difference in the odds of overweight/obesity by the age of the child when maternal depression occurred. Conclusion Chronic maternal depression during a child's early life was associated with child overweight/obesity at 7 years. Addressing maternal depression is a critical component of comprehensive obesity prevention and treatment strategies for Latino children. PMID:27007986

    Health psychology researchers have begun to focus greater attention on people's beliefs about health/illness since these beliefs can clearly affect behavior. This cross-sectional study aimed at (1) identifying the most common factors psychotic patients attribute their illness to and (2) assessing the association between causal attribution and illness perception (cognitive, emotional, and comprehensibility dimensions). Sixty-two patients (56.5% females) who had been treated for psychosis at a public psychiatric hospital in Mexico answered the Angermeyer and Klusmann Illness Attribution Scale and the Brief Illness Perception Questionnaire. Results showed that most patients attributed psychosis onset to social factors and that attribution to their personality might have an overwhelmingly negative effect on their lives. Acknowledging psychotic patient attributional beliefs and considering them in clinical practice could improve treatment efficacy and overall recovery success. This is particularly important in psychosis, since symptoms are often severe and/or persistent and require long-term treatment. PMID:25525628

    Background The aim of this study was to know the distribution of dental developmental alterations in the population requesting stomatological attention at the Admission and Diagnosis Clinic of our institution in Mexico City. Material and Methods We reviewed the archives and selected those files with developmental dental alterations. Analyzed data were diagnoses, age, gender, location and number of involved teeth. Results Of the 3.522 patients reviewed, 179 (5.1%) harbored 394 developmental dental alterations. Of them, 45.2% were males and 54.8% were females with a mean age of 16.7 years. The most common were supernumeraries, dental agenesia and dilaceration. Adults were 30.7% of the patients with dental developmental alterations. In them, the most common lesions were agenesia and supernumeraries. Mesiodens was the most frequently found supernumerary teeth (14.7%). Conclusions Our finding that 30.7% of the affected patients were adults is an undescribed and unusually high proportion of patients that have implications on planning and prognosis of their stomatological treatment.

    A pilot cross-sectional study was carried out in a group of 39 male brick manufacturers in San Luis Potosi, Mexico to identify epigenetic biomarkers of exposure to polycyclic aromatic hydrocarbons (PAHs). A questionnaire was used to compile the smoking and drinking habits, clinical history, working time, and socioeconomic characteristics of the participants. 1-Hydroxypyrene (1-OHP) levels were measured from urine samples using high-performance liquid chromatography, and genomic DNA was isolated from blood samples for methylation analysis using pyrosequencing. The mean 1-OHP level was 0.18 μg g(-1) creatinine (range 0.023-1.11), which was below the expected occupational exposure level. After adjusting for potential confounders, the 1-OHP urine concentration was negatively associated with DNA methylation of the interleukin 12 (β=-1.57; 95% CI: -2.9 to -0.23; p=0.02) and p53 gene promoters (β=-2.7; 95% CI: -5.46-0.06; p=0.055). Suggestive negative associations were also found for the TNF-α gene (β=-3.9; 95% CI:-8.28-0.48; p=0.08) and Alu sequences (β=-0.55; 95% CI:-1.25-0.16; p=0.12). Although the individual exposures to PAHs as estimated by urinary 1-OHP concentrations were low, changes in specific and global DNA methylation were observed.

  9. Earth's rotation and a feasibility study of a possible mexican participation with a VLBI station

    NASA Astrophysics Data System (ADS)

    Saucedo Morales, Julio Cesar; Kokina, Tatiana; Mendoza Araiza, Daniel

    This work begins by presenting a historical introduction on how the change in the Earth's rotation axis was first detected, and on related aspects of the discovery of precession and nutation phenomena. Newton's explanation of precession, the dynamical theory of nutation by Délambert as well as an acount of the first observatories dedicated to these studies are also discussed. In 1899 the International Latitude Service "ILS" was established, defining their main objectives, and started to determine the mean pole (1900 - 1905). In 1961 ILS was substituted by the International Polar Motion Service "IPMS". This service used laser telemetry to the Earth's artificial satelites "SAT", as well as to the Moon. Also in that period, the International Astronomical Union (IAU) aproved the MERIT international program, dedicated to monitor the Earth rotation intercomparing techniques of observation and analysis. It was in this program that "very long base interferometry" VLBI was used for the fist time, obtaining very good results. In 1987 the IAU started the International Earth Rotation Service "IERS" suported by its two networks ICRF and ITRF. The VLBI is said to be a powerful tool that could be used to solve global problems which have an impact in the countries' economies. In México we lack a rigid link in the geodesic network, which is linked to the global positional system NAVSTAR (GPS), as well as to the international system of coordinates (ITRF), and on the other hand there is a very high sysmic activity. We conclude by arguing that México ought to participate in IERS, as it has both scientists and infraestructure, such as the GMT, Sierra la Negra, Puebla, México. To achieve this a companion radiotelescope is needed. For this purpose, 5 telescopes are discussed, showing estimates for simultaneous reception as well as for the precission of the position of these radiotelescopes.

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

    Breast density (BD) is a risk factor for breast cancer. Aims. To describe BD patterns in asymptomatic Mexican women and the pathological mammographic findings. Methods and Material. Prospective, descriptive, and comparative study. Women answered a questionnaire and their mammograms were analyzed according to BI-RADS. Univariate (χ2) and conditional logistic regression analyses were performed. Results. In 300 women studied the BD patterns were fat 56.7% (170), fibroglandular 29% (87), heterogeneously dense 5.7% (17), and dense pattern 8.6% (26). Prevalence of fat pattern was significantly different in women under 50 years (37.6%, 44/117) and older than 50 (68.8%, 126/183). Patterns of high breast density (BD) (dense + heterogeneously dense) were observed in 25.6% (30/117) of women ≤50 years and 7.1% (13/183) of women >50. Asymmetry in BD was observed in 22% (66/300). Compression cone ruled out underlying disease in 56 cases. In the remaining 10, biopsy revealed one fibroadenoma, one complex cyst, and 6 invasive and 2 intraductal carcinomas. 2.6% (8/300) of patients had non-palpable carcinomas. Benign lesions were observed in 63.3% (190/300) of cases, vascular calcification in 150 cases (78.9%), and fat necrosis in 38 cases (20%). Conclusions. Mexican women have a low percentage of high-density patterns. PMID:23346398

    Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

    2016-11-01

    A high forest fire season of two to three years is regularly observed each decade in Mexican forests. This seems to be related to the presence of the El Niño phenomenon and to the amount of total solar irradiance. In this study, the results of a multi-cross wavelet analysis are reported based on the occurrence of Mexican forest fires, El Niño and the total solar irradiance for the period 1970-2014. The analysis shows that Mexican forest fires and the strongest El Niño phenomena occur mostly around the minima of the solar cycle. This suggests that the total solar irradiance minima provide the appropriate climatological conditions for the occurrence of these forest fires. The next high season for Mexican forest fires could start in the next solar minimum, which will take place between the years 2017 and 2019. A complementary space analysis based on MODIS active fire data for Mexican forest fires from 2005 to 2014 shows that most of these fires occur in cedar and pine forests, on savannas and pasturelands, and in the central jungles of the Atlantic and Pacific coasts.

    Pain and suffering are deeply embedded in the ethos of Mexican American culture. Consequently, it is not surprising to find that many Mexican Americans turn to their faith in an effort to deal with the pain and suffering that arise in their lives. The purpose of the current study is to explore the interface between pain, suffering, religion, and health among older Mexican Americans. Three major themes emerged from in-depth qualitative interviews with 52 older Mexican Americans. The first is concerned with whether pain and suffering are a necessary part of religious life, the second has to do with the potential benefits that pain and suffering may provide, and the third involves whether it is necessary to bear pain and suffering in silence. In the process of reviewing these themes, an effort is made to show how they may be linked with the physical and mental health of older Mexican Americans. PMID:21415936

    2011-01-01

    We know little about Mexican-American (MA) family adaptation to critical events in the informal caregiving experience but, in these days of economic and social turmoil, sons must sometimes step up to provide personal care for their aging mothers. This article compares two empirically real cases of MA males who provided such care, in lieu of a female relative. The cases are selected from a federally-funded, descriptive, longitudinal, mixed methods study of 110 MA caregivers and their care recipients. In case-oriented research, investigators can generate propositions (connected sets of statements) that reflect their findings and conclusions, and can be tested against subsequent cases: Caregiving strain and burden in MA males may have more to do with physical and emotional costs than financial ones; MA males providing personal care for their mothers adopt a matter-of-fact approach as they act “against taboo”; and this approach is a new way to fulfill family obligations.

    Research has documented a relation between parents' ethnic socialization and youth's ethnic identity, yet there has been little research examining the transmission of cultural values from parents to their children through ethnic socialization and ethnic identity. This study examines a prospective model in which mothers' and fathers' Mexican American values and ethnic socialization efforts are linked to their children's ethnic identity and Mexican American values, in a sample of 750 families (including 467 two-parent families) from an ongoing longitudinal study of Mexican American families (Roosa, Liu, Torres, Gonzales, Knight, & Saenz, 2008). Findings indicated that the socialization of Mexican American values was primarily a function of mothers' Mexican American values and ethnic socialization, and that mothers' Mexican American values were longitudinally related to children's Mexican American values. Finally, these associations were consistent across gender and nativity groups.

    2011-09-01

    Accurate age estimation has always been a problem for forensic scientists, and apposition of secondary dentine is often used as an indicator of age. Cameriere et al. studied the pulp/tooth area ratio by peri-apical X-ray images of the canines, to observe the apposition of secondary dentine. The present study examines the application of this technique in a Mexican identified sample coming from the Department of Physical Anthropology of the INAH, at Mexico City. The main aim of this work is to test the reliability of this method in a skeletal sample of a specific population, different from the samples used for its development. The obtained regression model explained 96.2% of total variance (R(2) = 0.962) with a standard error of estimate of 1.909 and a standard deviation of 1.947. These results demonstrate great reliability and that the age/secondary dentine relationship is not variable in this specific population.

    1978-04-01

    The discovery of a new mutant gene in stocks of the Mexican axolotl derived from breeding stock of the Hubrecht Laboratory, the Netherlands, is described. The gene appears to be a simple recessive and displays complete penetrance. ut/ut larvae develop normally through hatching, but begin to lag in growth and display characteristics defects in gill and limb formation shortly thereafter. The results of parabiosis of normal and mutant embryos, as well as embryological transplants of mutant limb and branchial rudiments, support the conclusion that the gene ut is expressed as an 'autonomous-cell lethal'. Despite gross morphological defects in ut/ut larvae, comparisons between normal and mutant animals of the protein spectra of various tissues and organs revealed no substantial differences. A subtle change in the metabolism of ut/ut larvae apparently, therefore, leads to developmental arrest.

    Objective To determine whether exposure to smoking imagery in films predicts smoking onset among never-smoking Mexican adolescents. Methods The analytic sample was comprised of 11- to 14-year old secondary school students who reported never having tried smoking at baseline, 83% (1741/2093) of whom were successfully followed up after one year. Exposure to 42 popular films that contained smoking was assessed at baseline, whereas smoking behavior and risk factors were assessed at baseline and follow up. Logistic regression was used to estimate bivariate and adjusted relative risks of trying smoking and current smoking at follow up. Results At follow up, 36% reported having tried smoking and 8% reported having smoked in the previous month. Students who were successfully followed up were exposed to an average of 43.8 minutes of smoking in the films they reported viewing at baseline. Adjusted relative risks (ARRs) indicated that students in the two highest levels of exposure to film smoking were more than twice as likely to have smoked in the previous 30 days at follow up (ARR3v1=2.44, 95%CI 1.31, 4.55; ARR4v1=2.23, 95% CI 1.19, 4.17). The adjusted relative risk of having tried smoking by follow up reached statistical significance only when comparing the 3rd highest to the lowest exposure group (ARR3v1=1.54, 95%CI 1.01, 2.64). Having a parent or best friend who smoked at baseline were the only other variables that independently predicted both outcomes. Conclusions Exposure to movie smoking is a risk factor for smoking onset among Mexican youth. PMID:19959694

    1982-01-01

    The developmet of Mexico's enormous hydrocarbon resources during the latter part of the 1970's provides an opportunity to examine the impact of Mexico's dependent-state status upon the use of the resource. Specifically, this study examines the hypothesis, drawn from the dependency literature, that the development of this resource within the context of dependency would lead to a greater internationalization of the Mexican economy and, in general, a deepening of Mexico's dependence rather than a lessening of that dependence as Mexico's political leaders suggest. The study also examines the impact of hydrocarbon development upon the growth of the Mexican state and state capitalism. Finally, the study examines the extent to which Mexico has sought to and has been able to modify the conditions of its dependence at the level of international exchange in the specific areas of trade, labor, and energy. Has the ''oil weapon'' been sufficiently powerful to modify substantially and fundamentally the terms of Mexico's dependence as some would argue should be able to do and as Mexico's leaders believed it would. Essentially, the study finds that Mexico's dependence has been exacerbated by the program of hydrocarbon development. Not only has the specific profile of oil, gas, and petrochemicals development been substantially impacted upon by Mexico's dependence, but the program for general economic development based upon the utilization of new oil revenues initiated a new era of dependent development for Mexico.

  18. HLA-DRB1 Class II antigen level alleles are associated with persistent HPV infection in Mexican women; a pilot study

    PubMed Central

    2013-01-01

    Background Persistent infection with high-risk human papillomavirus (HPV) is a major risk factor for malignant lesions and cervical cancer. A widely studied element in the search for genetic factors influencing risk HPV infection diseases is allelic variation of the human leukocyte antigen (HLA) locus. The study was designed to search for HLA susceptibility alleles contributing to the persistence of HPV infection in Mexican women. Methods A total of 172 subjects were divided into three groups: 1) HPV–persistent patients; 2) HPV–cleared; and 3) HPV–reinfected patients. They were screened for HPV types using a polymerase chain reaction (PCR). PCR-sequence specific oligonucleotide probes (PCR-SSOP) was used for HLA DRB1 and DQB1 typing. Results We observed that HLA-DQB1*0501 allele might be associated with susceptibility of reinfection with HPV (p = 0.01, OR = 4.9, CI 95% = 1.3 -18.7). Allele frequency of HLA-DRB1*14 was particularly reduced in patients with cancer when compared with the HPV–persistent group (p = 0.04), suggesting that this allele is a possible protective factor for the development of cervical cancer (OR = 2.98). HLA-DRB1*07 might be associated with viral clearance (p = 0.04). Conclusions Genetic markers for HPV infection susceptibility are different in each population, in Mexicans several HLA-DQB1 alleles might be associated with an enhanced risk for viral persistence. In contrast, DRB1*14, seems to confer protection against cervical cancer. PMID:24000898

    The current project sought to develop the Mexican Intercultural Competence Scale (MICS), which assesses group-specific skills and attributes that facilitate effective cultural interactions, among adults of Mexican descent. Study 1 involved an Exploratory Factor Analysis (N = 184) that identified five factors including Ambition/Perseverance, Networking, the Traditional Latino Culture, Family Relationships, and Communication. In Study 2, a Confirmatory Factor Analysis provided evidence for the 5-factor model for adults of Mexican origin living in the Midwest (N = 341) region of the U.S. The general findings are discussed in terms of a competence-based formulation of cultural adaptation and include theoretical and clinical implications.

    The research translation and community outreach goal of The University of Arizona's (UA) Superfund Basic Research Program and U.S.-Mexico Binational Center for Environmental Sciences and Toxicology is to increase human capacity and information dissemination to diverse stakeholders, including federal, state, and local government agencies as well as northern Mexican and border community stakeholders. Due to Arizona's demographic characteristics and the UA's proximity to the U.S. - Mexico border, activities target primarily Mexican and Mexican-American populations. With this in mind, a model has been established that pulls from human capital, community-based participatory research and public participation theories. The theories applied to our target population have resulted in the creation of a successful model that is used in both research translation and community outreach work. The model contains four components: community needs (participation), science translation (information), engagement (outreach), and training (education). Examples of how this model operates for various stakeholders involved in environmental science and health issues will be discussed. A case in point of how this model has been applied effectively is the partnership with promotoras (community health advocates) to do environmental science and health trainings to increase the knowledge base of specific populations disproportionately exposed to contaminants of concern. Additional case studies and methodologies used to develop innovative communicative tools (that takes into consideration cultural idiosyncrasies) for stakeholders at all levels in Arizona, the border, and Mexico will be highlighted, such as: 1) information sheets regarding local environmental issues for communities neighboring contaminated sites, 2) SciTransfer Bulletins targeting professional level stakeholders such as Project Managers, Community Involvement Coordinators and the general public, 3) coordinating technical and

    Aim The role of interleukin 17A (IL-17A) in the inflammatory process has caused interest in the potential significance of IL-17A as a biomarker for coronary artery disease (CAD). The aim of the present study was to evaluate the role of IL-17A gene polymorphisms as susceptibility markers for CAD in the Mexican population. Methods Four IL-17A gene polymorphisms (rs8193036, rs3819024, rs2275913 and rs8193037) were genotyped by 5’ exonuclease TaqMan assays in a group of 900 patients with premature CAD and 667 healthy controls (with negative calcium score by computed tomography), seeking associations with CAD and other metabolic and cardiovascular risk factors using logistic regression analyses. Results No single IL-17A polymorphism was associated with premature CAD, however two haplotypes (CAGG and TAGA) were significantly associated with increased risk of premature CAD (OR = 1.35, 95% CI: 1.00–1.84, P = 0.018 and OR = 2.09, 95% CI: 1.16–3.76, P = 0.003, respectively). Moreover, rs3819024 was associated with increased levels of visceral abdominal fat (P = 0.002) and rs8193036 was significantly associated with risk of central obesity (P = 0.020), hypertriglyceridemia (P = 0.027), and metabolic syndrome (P = 0.027) in the premature CAD group, under dominant models adjusted by age, gender, BMI, smoking history, alcohol consumption, and treatment. Conclusion The results suggest that IL-17A haplotypes are involved in the risk of developing premature CAD and some IL-17A polymorphisms are associated with cardiovascular risk factors in Mexican individuals with premature CAD.

    Biobank-based research in Mexico is mostly governed by research and data protection laws. There is no direct mention of biobanks in either statutory or regulatory law besides a requirement that the Federal Ministry of Health and a Mexican institution devoted to scientific research approve the transfer of biological materials outside of Mexico for population genetics research purposes. Such requirements are the basis of Genomic Sovereignty in Mexico, but such requirements have not prevented international collaboration. In addition, Mexican law singles out genetic research in informed consent provisions, but it does not specify whether all biobank-based research is genetic research. In order to facilitate international collaboration on biobank-based research, Mexico should directly address biobanking in its laws, building on the research framework and data protection framework already in place.

    Aims/hypothesis 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. Methods 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. Results 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. Conclusions/interpretation 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. PMID:21573907

    The results of an immigrant student census in a California port-of-entry school district are used to describe the educational backgrounds of Mexican immigrant students and to distinguish types of Mexican immigrant students by school entry patterns. Interviews with recently arrived Mexican immigrant parents reveal the educational and occupational expectations they hold for their children in the US. The study findings are used as a basis for raising policy questions and generating research issues. The most notable observation from the study is that the children of Mexican immigrants in La Entrada do not migrate once they are in school. Parents may be migrating back and forth between the US and Mexico, but children once in La Entrada do not leave the school to return to school in Mexico. The study suggests that the parents of immigrant students do not know how the US educational system works but they are interested in helping teachers educate their children.

    Identification of confounding factors, evaluation of their influence on cause-effect associations, and the introduction of appropriate ways to account for these factors are important considerations in designing case-control studies. This paper presents designs useful for these purposes, after first providing a statistical definition of a confounding factor. Differences in the ability to identify and evaluate confounding factors and estimate disease risk between designs employing stratification (matching) and designs randomly sampling cases and controls are noted. Linear logistic models for the analysis of data from such designs are described and are shown to liberalize design requirements and to increase relative risk estimation efficiency. The methods are applied to data from a multiple factor investigation of lung cancer patients and controls. PMID:540588

    The Latina Paradox, or persistent, unexplained variation in low birth weight rates in recently immigrated Mexican women and the trend toward higher rates in subsequent generations of Mexican American women, is most often attributed to unidentified sociocultural causes. We suggest herein that different disciplinary approaches can be synthesized under the constructs of reproductive habitus and subjective social status to identify influences of sociocultural processes on birth weight. Reproductive habitus are "modes of living the reproductive body, bodily practices, and the creation of new subjects through interactions between people and structures" (Smith-Oka, 2012: 2276). Subjective social status infers comparison of self to others based on community definitions of status or socioeconomic status (Adler 2007). We present results from a prospective study of low-income Mexican immigrant and Mexican American women from south Texas that tested the ability of reproductive habitus and subjective social status to elucidate the Latina Paradox. We hypothesized that reproductive habitus between Mexican immigrant women and Mexican American women inform different subjective social statuses during pregnancy, and different subjective social statuses mediate responses to psychosocial stressors known to correlate with low birth weight. Six hundred thirty-one women were surveyed for psychosocial health, subjective social status, and reproductive histories between 2011 and 2013. Eighty-three women were interviewed between 2012 and 2013 for status during pregnancy, prenatal care practices, and pregnancy narratives and associations. Birth weight was extracted from medical records. Results were mixed. Subjective social status and pregnancy-related anxiety predicted low birth weight in Mexican immigrant but not Mexican American women.

    We report the characteristics of 691 Mexican patients with Huntington's disease (HD). These patients, representing 401 families, constitute the largest series of Mexican HD cases as yet described in the literature. We found the clinical characteristics of these patients to be similar to those of other populations, but we observed a higher frequency of infantile cases, a shorter disease duration and a lower suicide rate. In 626 cases, for which molecular analyses were available, CAG-trinucleotide expansion size ranged from 37-106 repeats. The large number of CAG repeats (19.04 +/- 3.02) in normal alleles and the presence of new mutations suggest that the overall prevalence of HD in the Mexican population could be expected to be within range of, or higher than, that reported for Europeans.

    For numerous reasons, children of Mexican descent experience many health disparities. One strategy for addressing these disparities is to increase health promotion and protection behaviors that mothers use with their preschool children. Limited literature is available on such practices used by mothers of Mexican descent with their healthy preschool children. This study explored child health promotion and protection practices used by mothers of Mexican descent. A naturalistic design, guided by Spradley's ethnographic interview techniques, was selected for this study. The sample included 9 Mexican-descent mothers from an urban U.S. community with healthy preschool children. Despite significant challenges, participants promoted and protected the health of their preschool children by al cuidado (taking care) and by being al pendiente (being mindful) of balancing the health of their children's bodies, minds, and souls. Understanding these mothers' approaches allows the creation of culturally sensitive health programs that can build on existing maternal strengths.

    Mexican red salsa is one of the most common side dishes in Mexican cuisine. According to data on foodborne illnesses collected by the Centers for Disease Control and Prevention, salsa was associated with 70 foodborne illness outbreaks between 1990 and 2006. Salsa ingredients such as tomatoes, cilantro, and onions often have been implicated in foodborne illness outbreaks. Mexican-style restaurants commonly prepare a large batch of red salsa, store it at refrigeration temperatures, and then serve it at room temperature. Salmonella is one of the top etiologies in foodborne illness outbreaks associated with salsa, and our preliminary studies revealed the consistent presence of Staphylococcus aureus in restaurant salsa. In the present study, we evaluated the survival of Salmonella Enteritidis and S. aureus inoculated into restaurant-made salsa samples stored at ambient (20 degrees C) and refrigeration (4 degrees C) temperatures. These test temperature conditions represent best-case and worst-case scenarios in restaurant operations. Salmonella survived in all samples stored at room temperature, but S. aureus populations significantly decreased after 24 h of storage at room temperature. No enterotoxin was detected in samples inoculated with S. aureus at 6.0 log CFU/g. Both microorganisms survived longer in refrigerated samples than in samples stored at room temperature. Overall, both Salmonella and S. aureus survived a sufficient length of time in salsa to pose a food safety risk. PMID:20537270

    2004-08-01

    We assessed the relationships between chronic arsenic (As) exposure, human papilloma virus (HPV) contact and non-melanoma skin cancer (NMSC) by means of a dermatology clinic-based case-control study (42 cases and 48 controls) in Region Lagunera, Mexico, where chronic As poisoning is endemic. Exposure was determined through detailed history of residence in the As-contaminated area and measurement of As levels in drinking water and urine. We used a consensus epitope from the central region of L1 protein of the HPV family to determine antibodies against HPV. A history of As exposure and HPV seropositivity were associated with increased NMSC risks. A history of exposure to high levels of As increased the risk for NMSC (OR = 4.53; P = 0.11) in the group of seronegative HPV patients. A positive response to HPV significantly increased the OR for NMSC to 9.04 (P = 0.01) when history showed exposure to low levels of As. Interestingly, the OR was significantly increased to 16.5 (P = 0.001) when both exposure to high levels of As and HPV seropositivity were present. In addition, the presence of NMSC increased the OR (5.45; P = 0.03) for a positive response to HPV when history showed exposure to low levels of As, but the OR was increased to 8.0 (P = 0.005) in the cases with high exposure levels. Thus, HPV infection could constitute an additional risk factor for NMSC development in humans chronically exposed to As. However, further studies with additional populations are needed to determine the interaction between HPV and As exposure in NMSC.

    1984-01-01

    This study was conceived as an opportunity to examine the impact that the condition of dependency would have upon Mexico's effort to develop its huge petroleum resources in the mid 1970s. It is hardly a pleasant tale and one that provides little encouragement for those searching for solutions to underdevelopment within the contemporary Mexican political setting. Despite the fact that the study details a failed development project, the alternative to the model in place is far from obvious, as painful as that observation may be. Indeed, the failure of the development project and the analysis presented here of that failure is not directly suggestive of a preferable development alternative. While a ''socialist'' model is usually implied by dependence analysis, the socialist alternative frankly provides little guarantee of a prospect of long term viability, self-directed development and essential political and human rights to oppressed people.

    We study how the health insurance coverage of Mexican immigrants changes with time in the U.S. Cross sectional estimates indicate that time since arrival is negatively correlated with the probability of being uninsured for both male and female Mexican immigrants, and about a third of the decline could be attributed to civic and labor market incorporation of Mexican immigrants. However, much of the relationship between time in the U.S. and health insurance coverage, after adjusting for demographic and labor market factors, is due to failure to control for age at arrival and period of arrival. Estimates from longitudinal analyses suggest that there is no systematic relationship between time in the U.S. and health insurance of Mexican immigrants, although imprecision in the fixed effects estimates makes it difficult to draw firm conclusions.

    PubMed

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

  20. Alkalic (ocean-island basalt type) and calc-alkalic volcanism in the Mexican volcanic belt: A case for plume-related magmatism and propagating rifting at an active margin?

    NASA Astrophysics Data System (ADS)

    Márquez, Alvaro; Oyarzun, Roberto; Doblas, Miguel; Verma, Surendra P.

    1999-01-01

    The Mexican volcanic belt has been traditionally regarded as a classic case of subduction-related calc-alkalic volcanism. However, a series of geologic, geophysical, and petrological arguments makes this simple relationship doubtful. A seismic gap beneath the belt, a large-scale mantle anomaly, a graben triple-junction domain, and the presence of volumetrically important oceanic-island basalt (OIB) volcanism throughout the belt suggest a more complex tectonic scenario involving plume- and subduction-related processes. We here propose a model involving the development of a propagating rift opening from west to east in response to plume activity. The process started in Miocene time within the western sector of the belt (Guadalajara) and gave rise to a graben triple junction and OIB-type and calc-alkalic volcanism. Extension and volcanism proceeded to the east, giving rise to progressively younger ages for the initiation of OIB-type volcanism: (1) Miocene in the west (e.g., Guadalajara), (2) Pliocene in the central zone (e.g., Michoacán-Guanajuato), and (3) Quaternary farther east (e.g., Chichinautzin). Geochemical evidence suggests that part of the modern calc-alkalic volcanism (e.g., Chichinautzin) may be derived from magma mixing between the OIB mafic magmas and silicic, crust-derived magmas. However, we do not preclude some influence of the subducting slab in the generation of other (e.g., Jorullo) calc-alkalic volcanic rocks. Our model suggests a currently unrooted upper plume attached to the subcontinental lithosphere, which defines a hot zone beneath the Mexican volcanic belt.

  1. Niños Sanos, Familia Sana: Mexican immigrant study protocol for a multifaceted CBPR intervention to combat childhood obesity in two rural California towns

    2013-01-01

    Background Overweight and obese children are likely to develop serious health problems. Among children in the U.S., Latino children are affected disproportionally by the obesity epidemic. Niños Sanos, Familia Sana (Healthy Children, Healthy Family) is a five-year, multi-faceted intervention study to decrease the rate of BMI growth in Mexican origin children in California’s Central Valley. This paper describes the methodology applied to develop and launch the study. Methods/Design Investigators use a community-based participatory research approach to develop a quasi-experimental intervention consisting of four main components including nutrition, physical activity, economic and art-community engagement. Each component’s definition, method of delivery, data collection and evaluation are described. Strategies to maintain engagement of the comparison community are reported as well. Discussion We present a study methodology for an obesity prevention intervention in communities with unique environmental conditions due to rural and isolated location, limited infrastructure capacity and limited resources. This combined with numerous cultural considerations and an unstable population with limited exposure to researcher expectations necessitates reassessment and adaptation of recruitment strategies, intervention delivery and data collection methods.

    Several clinical trials have substantiated the efficacy of the co-administration of statins like atorvastatin (ATO) and fibrates. Without information currently available about the interaction between the two drugs, a pharmacokinetic study was conducted to investigate the effect when both drugs were co-administered. The purpose of this study was to investigate the pharmacokinetic profile of tablets containing ATO 20 mg, or the combination of ATO 20 mg with fenofibrate (FNO) 160 mg administered to healthy Mexican volunteers. This was a randomized, two-period, two-sequence, crossover study; 36 eligible subjects aged between 20–50 years were included. Blood samples were collected up to 96 h after dosing, and pharmacokinetic parameters were obtained by non-compartmental analysis. Adverse events were evaluated based on subject interviews and physical examinations. Area under the concentration-time curve (AUC) and maximum plasma drug concentration (Cmax) were measured for ATO as the reference and ATO and FNO as the test product for bioequivalence design. The estimation computed (90% confidence intervals) for ATO and FNO combination versus ATO for Cmax, AUC0-t and AUC0-∞, were 102,09, 125,95, and 120,97%, respectively. These results suggest that ATO and FNO have no relevant clinical-pharmacokinetic drug interaction. PMID:25688207

    The generation of electricity through the use of radioactive material at the nuclear power plant is inevitably associated with the production of wastes, some of which have potential impact on the biosphere. The objective of the present investigation was to provide information for evaluating the presumed impact of the Mexican Nuclear Power Plant "Laguna Verde" on the natural populations. Two sibling species that live in the immediate vicinity, Drosophila melanogaster and D. simulans have been studied for several traits in a long term study. The present study describes results for the desiccation resistance (DR) trait obtained during the period from 1995 to 2002. Flies were collected at two sites, one near the reactors and another farther away. The data obtained confirmed that D. melanogaster had higher DR values than D. simulans at both sites. The analysis of the results obtained from both species of the site closer to the reactor indicated that the values of the DR in the operational stage did not change, compared with those in the preoperational stage previously analyzed. Therefore, the significant differences found between the monitored sites did not seem to be associated to the operation of the reactors. PMID:17016749

    It has been hypothesized that the greater prevalence of non-insulin-dependent diabetes mellitus (NIDDM) in Mexicans may be related to their greater degree of Amerindian genetic admixture (AGA). The aim of this unmatched case-control study was to correlate the prevalence of NIDDM with AGA in 10 Mexican Mestizo populations non-randomly selected by surname. A sample of 1,699 unrelated persons, >44 years and residing in the state of Nuevo León, was selected on the basis of paraphyletic or polyphyletic surnames and interviewed in the Instituto Mexicano del Seguro Social (IMSS). All subjects received a medical examination, and diabetes was diagnosed on the basis of World Health Organization criteria. Three genetic marker systems were analyzed, and the percentage of AGA was calculated. Logistic regression analysis was performed with the prevalence as the dependent variable and sex and surname as the independent variables. The Spearman rank-order correlation analysis was calculated between the age-adjusted prevalence (45-75+ years) and AGA. The correlation revealed a pattern of increasing prevalence of NIDDM with increasing Amerindian ancestry by surname. Am. J. Hum. Biol. 12:721-728, 2000. Copyright 2000 Wiley-Liss, Inc. PMID:11534064

  5. Teresa Urrea: Mexican mystic, healer, and apocalyptic revolutionary.

    PubMed

    Nava, Alex

    2005-01-01

    This article is a study of the mystical and apocalyptic dimensions of Teresa Urrea. As explained in this article, Urrea’s mystical experiences and visions are unique for their connection with a propheticapocalyptic and political worldview. This apocalyptic dimension is more than a communication of a hidden message or spiritual world; it also includes a reading of history that is catastrophic and discontinuous. The crisis and terror of history are given expression in Urrea’s mystical and apocalyptic pronouncements. In particular, the chaotic and oppressive circumstances of Mexican society during the dictatorship of Porfirio Diaz was confronted and denounced in Urrea’s mystical and apocalyptic ministry. This apocalyptic healer castigated those culpable or even complicit with the injustices affecting the indigenous communities of Mexico during the late nineteenth century. In the case of Urrea, the transformation and healing of Church and society was an important aspect of her spiritual, healing powers. Because Urrea possessed neither arms nor the weapon of the pen, her sole weapon became her mystical experiences and the insight and healing powers that flowed from them. People of Mexico—especially indigenous groups—began to flock to her hoping that she would bring God’s presence to the troubled and chaotic circumstances of their lives. Her compassion and tenderness for the afflicted as well as the apocalyptic expectations that she stirred up among the indigenous groups of Northern Mexico were enough to get this mystical-political Mexican mestiza exiled from her homeland.

  6. Case studies in teaching evolution: The intersection of dilemmas in practice

    NASA Astrophysics Data System (ADS)

    Fisher, Rachel

    Despite recent science education reform documents citing evolution as a core concept to be taught in grades K-12, research shows problems with how it is currently taught. Evolution is often avoided, teachers minimize its importance within biology, infuse misconceptions, and/or interject non-scientific ideologies into lessons. My research focused on how teachers in two geographically and culturally distinct school districts in the southwestern U.S. negotiate dilemmas during an evolution unit. One school district was rural and had a large population of Mormon students, while the other district was urban, with a large majority Mexican/Mexican-American students. Using a case study approach, I observed three biology teachers during their evolution lessons, interviewed them throughout the unit, co-planned lessons with them, and collected artifacts from this unit, including anonymous student work. I also included data from four genetics lessons for each teacher to determine if the issues that arose during the evolution unit were a result of the general practice of the teacher, or if they were unique to evolution. Findings showed teachers' backgrounds and comfort levels with evolution, in addition to their perceptions of community context, affected how they negotiated pedagogical, conceptual, political, and cultural dilemmas. This study's findings will inform in-service teachers' future practice and professional development tools to aid with their teaching---this may include methods to negotiate some of the political (e.g. state standards) or cultural (e.g. religious resistance) issues inherent to teaching evolution.

    Studies of stress consistently have linked individuals' experiences of stress to maladjustment, but limited attention has been given to cultural stressors commonly experienced by minority individuals. To address this, the current study examined the links between cultural stressors and prospective changes in mental health symptoms in a sample of 710 (49 % female) Mexican American youth. In addition, the moderating role of both family and neighborhood cohesion was examined. In-home interviews were completed with youth, mothers (required) and fathers (optional) to collect data on youth's experiences of cultural stressors (discrimination and language hassles) and internalizing/externalizing behavior, and mothers' report of family cohesion and mothers' and fathers' report of neighborhood cohesion. Analyses revealed that youth's experiences of discrimination and language hassles at 5th grade were related positively to increases in internalizing symptoms at 7th grade. Additionally, youths who reported higher levels of language hassles in 5th grade experienced increases in externalizing symptoms across the 2-year span. Both family and neighborhood cohesion emerged as significant moderating factors but their impact was conditional on youth's gender and nativity. Limitations and future implications are discussed.

    Staphylococcus aureus is the number one cause of hospital-acquired infections. Understanding host pathogen interactions is paramount to the development of more effective treatment and prevention strategies. Therefore, whole exome sequence and chip-based genotype data were used to conduct rare variant and genome-wide association analyses in a Mexican-American cohort from Starr County, Texas to identify genes and variants associated with S. aureus nasal carriage. Unlike most studies of S. aureus that are based on hospitalized populations, this study used a representative community sample. Two nasal swabs were collected from participants (n = 858) 11-17 days apart between October 2009 and December 2013, screened for the presence of S. aureus, and then classified as either persistent, intermittent, or non-carriers. The chip-based and exome sequence-based single variant association analyses identified 1 genome-wide significant region (KAT2B) for intermittent and 11 regions suggestively associated with persistent or intermittent S. aureus carriage. We also report top findings from gene-based burden analyses of rare functional variation. Notably, we observed marked differences between signals associated with persistent and intermittent carriage. In single variant analyses of persistent carriage, 7 of 9 genes in suggestively associated regions and all 5 top gene-based findings are associated with cell growth or tight junction integrity or are structural constituents of the cytoskeleton, suggesting that variation in genes associated with persistent carriage impact cellular integrity and morphology.

  15. High prevalence of autoantibodies to RNA helicase A in Mexican patients with systemic lupus erythematosus

    PubMed Central

    2010-01-01

    Introduction Autoantibodies to RNA helicase A (RHA) were reported as a new serological marker of systemic lupus erythematosus (SLE) associated with early stage of the disease. Anti-RHA and other autoantibodies in Mexican SLE patients and their correlation with clinical and immunological features were examined. Methods Autoantibodies in sera from 62 Mexican SLE patients were tested by immunoprecipitation of 35S-labeled K562 cell extract and enzyme-linked immunosorbent assay (anti-U1RNP/Sm, ribosomal P, β2GPI, and dsDNA). Anti-RHA was screened based on the immunoprecipitation of the 140-kDa protein, the identity of which was verified by Western blot using rabbit anti-RHA serum. Clinical and immunological characteristics of anti-RHA-positive patients were analyzed. Results Anti-RHA was detected in 23% (14/62) of patients, a prevalence higher than that of anti-Sm (13%, 8/62). Prevalence and levels of various autoantibodies were not clearly different between anti-RHA (+) vs. (-) cases, although there was a trend of higher levels of anti-RHA antibodies in patients without anti-U1RNP/Sm (P = 0.07). Both anti-RHA and -Sm were common in cases within one year of diagnosis; however, the prevalence and levels of anti-RHA in patients years after diagnosis did not reduce dramatically, unlike a previous report in American patients. This suggests that the high prevalence of anti-RHA in Mexican patients may be due to relatively stable production of anti-RHA. Conclusions Anti-RHA was detected at high prevalence in Mexican SLE patients. Detection of anti-RHA in races in which anti-Sm is not common should be clinically useful. Racial difference in the clinical significance of anti-RHA should be clarified in future studies. PMID:20064217

    Among the candidate genes for Parkinson's disease (PD), SNCA has replicated association in different populations. Besides other known mutations in the SNCA gene, the rs3857059 variant has also been linked to various neurodegenerative disorders. Therefore, the aim of the present study was to search for association of this variant and sporadic PD in Mexican Mestizo patients. A case-control study was performed including 241 individuals, 106 patients, and 135 healthy controls. Genotyping was performed using real-time PCR. The rs3857059 variant demonstrated an association with PD in Mexican Mestizos (OR = 2.40, CI, 1.1 to 5.1, p = 0.02) under the recessive model. In addition, a gender effect was found for the GG genotype in females (OR = 1.31, CI, 1.01 to 1.7, p = 0.037). This is the first study to confirm an association of the rs3857059 variant with PD and also to show a gender effect. Our data contribute to the elucidation of the link between rs3857059 and susceptibility to PD observed in the Mexican Mestizo population. PMID:27332068

    Older men are less likely than older women to receive depression treatment. Latino older men in particular have been found to have significantly lower rates of depression treatment than their white-non-Mexican (WNM) counterparts. Prior research has shown that men are less likely than women to express overt affect and/or report depression symptoms that may prompt primary care physicians' inquiry about depression. Previous studies have overlooked the idioms of distress common among older men. This study investigates: a) the range of idioms of distress that emerge in the narratives of depressed older men, and b) the use of these idioms among depressed WNM and Mexican-origin older men. The present report is based on qualitative data collected through the Men's Health and Aging Study (MeHAS), a mixed-method study of clinically depressed WNM and Mexican-origin older (65 and above) men recruited in primary care settings. Qualitative analysis of 77 interviews led to identification of idioms of distress and informed idiom categories. Study findings show that: a) both groups of men utilized a range of idioms of distress that met current DSM criteria for depression, b) both groups were also likely to utilize idioms that feel outside clinical depression criteria, and c) there were similarities as well as differences between WNM and Mexican-origin men. This study provides a larger vocabulary that clinicians might consider in recognizing depression and initiating depression care for older men from diverse ethnic backgrounds. This is important to improve depression care among older men in general and those of Mexican-origin in particular.

    Starr County, Texas, a Texas-Mexico border community, was the site of a study involving culturally-appropriate education and group support for Mexican Americans with type 2 diabetes. Data were collected from 63 subjects on frequency of diabetes-related symptoms during the previous month and on self-care symptom treatments. On average, subjects were 57-year-old females, diagnosed with diabetes for 10 years, and exhibiting HbA1c levels of 12.5%. Almost 50% experienced excessive urination, excessive thirst, shakiness/nervousness, and numbness and/or tingling in their extremities. More than 50% of those who experienced symptoms did not view them as serious. Only one subject checked blood sugar levels when symptoms occurred. Significantly higher mean glycosylated hemoglobin levels were found for individuals who experienced dizziness and/or chest pain compared with those who did not. A variety of self-care treatments were employed, including over-the-counter medications and home remedies. PMID:9677951

    Background: Trichothiodistrophy (TTD) is a rare autosomal recessive condition that is characterized by a specific congenital hair shaft dysplasia caused by deficiency of sulfur associated with a wide spectrum of multisystem abnormalities. In this article, we study clinical, microscopic, and ultrastructural findings of 20 patients with TTD with the aim to add further insights regarding to this rare condition. Additionally, analyses of our results are compared with those extracted from the literature in order to enhance its comprehensibility. Materials and Methods: Twenty cases of TTD were included: 7 from Mexico and 14 from Spain. Clinical, microscopic, scanning electron microscopy (SEM) studies and X-ray microanalysis (XrMa) were carried out in all of them. Genetic studies were performed in all seven Mexican cases. Patients with xeroderma pigmentosum and xeroderma pigmentosum/TTD-complex were excluded. Results: Cuticular changes and longitudinal crests of the hair shaft were demonstrated. These crests were irregular, disorganized, following the hair longest axis. Hair shaft sulfur deficiency was disposed discontinuously and intermittently rather than uniformly. This severe decrease of sulfur contents was located close to the trichoschisis areas. Only five patients did not show related disturbances. Micro-dolichocephaly was observed in five cases and represented the most frequent facial dysmorphism found. It is also remarkable that all patients with urologic malformations also combined diverse neurologic disorders. Moreover, three Mexican sisters demonstrated the coexistence of scarce pubic vellus hair, developmental delay, onychodystrophy, and maxillar/mandibullar hypoplasia. Conclusions: TTD phenotype has greatly varied from very subtle forms to severe alterations such as neurologic abnormalities, blindness, lamellar ichthyosis and gonadal malformations. Herein, a multisystem study should be performed mandatorily in patients diagnosed with TTD. PMID:23180925

    Spinocerebellar ataxia type 7 (SCA7) is a neurodegenerative disorder characterized by progressive cerebellar ataxia associated with macular degeneration that leads, in the majority of patients, to loss of autonomy and blindness. The cause of the disease has been identified as (CAG) n repeat expansion in the coding sequence of the ATXN7 gene on chromosome 3p21.1. SCA7 is one of the least common genetically verified autosomal dominant cerebellar ataxias found worldwide; however, we previously identified the Mexican population showing high prevalence of SCA7, suggesting the occurrence of a common founder effect. In this study, haplotype analysis using four SCA7 gene-linked markers revealed that all 72 SCA7 carriers studied share a common haplotype, A-254-82-98, for the intragenic marker 3145G/A and centromeric markers D3S1287, D3S1228, and D3S3635, respectively. This multiloci combination is uncommon in healthy relatives and Mexican general population, suggesting that a single ancestral mutation is responsible for all SCA7 cases in this population. Furthermore, genotyping using 17 short tandem repeat markers from the non-recombining region of the Y chromosome and further phylogenetic relationship analysis revealed that Mexican patients possess the Western European ancestry, which might trace the SCA7 ancestral mutation to that world region.

    Among Mexican Americans the prevalence of gallbladder disease is markedly elevated. Previous data from both genetic admixture and family studies indicate that there is genetic component to the occurrence of gallbladder disease in Mexican Americans. However, prior to this study no formal genetic analysis of gallbladder disease had been carried out nor had any contributing gene been identified. The results of complex segregation analysis in a sample of 232 Mexican Americans with age- and gender-specific effects influencing the occurrence of gallbladder disease. The estimated frequency of the allele increasing susceptibility was 0.39. The lifetime probabilities that an individual will be affected by gallbladder disease were 1.0, 0.54, and 0.00 for females of genotypes {open_quotes}AA{close_quotes}, {open_quotes}Aa{close_quotes}, and {open_quotes}aa{close_quotes}, respectively, and 0.68, 0.30, and 0.00 for males, respectively. Human cholesterol 7a-hydroxylase is the rate-limiting enzyme in bile acid synthesis. The results of an association study in both a random sample and a matched case/control sample showed that there is a significant association between cholesterol 7a-hydroxylase gene variation and the occurrence of gallbladder disease in Mexican Americans males but not in females. For loci in the 5{prime}-end of the cholesterol 7a-hydroxylase gene, the frequency of the susceptibility alleles was twice as high in gallbladder disease patients compared to controls. The results of a linkage analysis provide evidence that the cholesterol 7a-hydroxylase gene and the inferred gallbladder disease gene are genetically linked.

    A scanning electron microscopy, histological, and immunochemical investigation examined the effects of the mutant gene (e) upon hypothalamic development in the Mexican axolotl. The adult eyeless mutant is sterile. Previous studies indicated that this reproductive defect was due to the mutation's effect upon the hypothalamus. The present study demonstrated the pleiotropic effects of the eyeless gene upon development of the hypothalamus. Scanning electron microscopy studies looked at the early ontogeny of the hypothalamohypophyseal system. The major morphological difference observed in the hypothalamus of normals compared to eyeless mutants was the reduced nature or complete lack of a preoptic recess in eyeless mutants. Early embryonic tissue movements also differed when normal siblings were compared to eyeless mutant axolotls. Histological examination looking for paraldehyde-fuchsin-positive secretory neurons revealed a paired nucleus preopticus in both normals and eyeless mutants, but this region lacked the emanating paraldehyde-fuchsin-positive fiber tracts in eyeless mutants. The neurohypophysis of the eyeless mutants was atrophied and contained far less paraldehyde-fuchsin-positive material when compared to normal axolotls. Immunochemical studies were done to look at the distribution of immunoreactive luteinizing-hormone-releasing hormone (ir-LHRH) in brains of eyed and eyeless mutant axolotls of different stages. This study detected deficiencies in ir-LHRH in the anterior hypothalamus of eyeless mutants. In general in the eyeless mutant axolotl, the observed anterior hypothalamic deficiencies are comparable to those observed in anurans which have had their optic vesicles removed. These observations suggest a possible utility of the eyeless mutant axolotl for studies concerned with endocrine development in the absence of hypothalamic modulation.

    We report the case of patient MN, diagnosed with frontotemporal dementia, who exhibited a severe impairment in writing letters and words in upper-case print in the face of accurate production of the same stimuli in lower-case cursive. In contrast to her written production difficulties, MN was unimpaired in recognizing visually presented letters and words in upper-case print. We find a modest benefit of visual form cueing in the written production of upper-case letters, despite an inability to describe or report visual features of letters in any case or font. This case increases our understanding of the allographic level of letter-shape representation in written language production. It provides strong support for previous reports indicating the neural independence of different types of case and font-specific letter-shape information; it provides evidence that letter-shape production does not require explicit access to information about the visual attributes of letter shapes and, finally, it reveals the possibility of interaction between processes involved in letter-shape production and perception.

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    These case studies provide small, selected samples of the results of assessments of articulation skills and their phonologic applications and give some information related to velopharyngeal function during speech. These illustrations were based chiefly on perceptual assessment of speech because this type of assessment is used routinely by SLPs, and does not require instrumentation. Indicators for referral and communication to a cleft palate team were derived from the perceptual evaluation. Other articles in this issue discuss procedures for evaluation in considerable detail. Early identification of possible velopharyngeal problems and early referral to a cleft palate team can help to resolve speech, language, and hearing disorders related to cleft palate and velopharyngeal dysfunction. People who comprise cleft palate and craniofacial teams are most likely to have the experience, and the special instrumentation necessary, to make a definitive diagnosis. The team's comprehensive multidisciplinary evaluation should lead to thorough consideration of the many factors that are important for treatment planning. The information and services provided by the team will assist the audiologist and SLP in the conduct of their services for these clients. In this way, the communication disorders specialist becomes an affiliate of the team. The affiliate not only acts as a referent, but also may provide the necessary longitudinal services. The best interests of the client are promoted by ongoing communication between the team and the affiliates of the team.

    This study uses data from the 2000 Census and 2005-2009 American Community Survey to examine the impact of undocumented Mexican migration to new destinations on residential segregation between Mexican immigrants and native-born whites and native-born blacks. We find that Mexican-white and Mexican-black segregation is higher in new Mexican gateways than in established areas and that, for Mexican-immigrant segregation from whites, this heightened level of residential segregation in new destinations can be explained by the high presence of unauthorized Mexican immigrants living there which tends to bolster segregation between the two groups. By contrast, Mexican-immigrant segregation from native-born blacks tends to be lower in areas with larger undocumented populations, a pattern that is especially true in new destinations. Neither of these opposing effects of legal status on Mexican-immigrant segregation can be explained by compositional differences in assimilation (English ability and earnings) between documented and undocumented immigrants nor by structural variation in metropolitan areas, suggesting a unique association between legal status and segregation.

    Missing data often occur in cross-sectional surveys and longitudinal and experimental studies. The purpose of this study was to compare the prediction of self-rated health (SRH), a robust predictor of morbidity and mortality among diverse populations, before and after imputation of the missing variable "yearly household income." We reviewed data from 4,162 participants of Mexican origin recruited from July 1, 2002, through December 31, 2005, and who were enrolled in a population-based cohort study. Missing yearly income data were imputed using three different single imputation methods and one multiple imputation under a Bayesian approach. Of 4,162 participants, 3,121 were randomly assigned to a training set (to derive the yearly income imputation methods and develop the health-outcome prediction models) and 1,041 to a testing set (to compare the areas under the curve (AUC) of the receiver-operating characteristic of the resulting health-outcome prediction models). The discriminatory powers of the SRH prediction models were good (range, 69-72%) and compared to the prediction model obtained after no imputation of missing yearly income, all other imputation methods improved the prediction of SRH (P < 0.05 for all comparisons) with the AUC for the model after multiple imputation being the highest (AUC = 0.731). Furthermore, given that yearly income was imputed using multiple imputation, the odds of SRH as good or better increased by 11% for each $5,000 increment in yearly income. This study showed that although imputation of missing data for a key predictor variable can improve a risk health-outcome prediction model, further work is needed to illuminate the risk factors associated with SRH.

In 1970, 42% of Mexican Americans were indigent, making approxiamtely 4200 annually. The Mexican American poor can be categorized into newly arrived aliens or 2nd or 3rd generation American citizens. In the 1st instance, the couple is young and English is not spoken. 2nd or 3rd generation Mexican Americans speak English. The persistent socioeconomic status of the Mexican American relates directly to the level of education. 52% of all Mexican Americans do not finish high school. Paz and Remos described the Mexican in terms of Adler's inferiority model. Murillo stated that to an individual, the family--whether nuclear or extended--is the center of life. The inherent responsibility is that the individual behave properly lest the family be disgraced. The family provides emotional and material security. Familism was seen as a deterrant to utilization of health care services, although some studies claim opposing views. Familism and occupational stability related positively to seeking medical care when ill. Hayden believed that supreme male dominance, individualism, pride, wife beating, aversion to contraceptives, and other characteristics were attributable to machismo. A predominant pattern in Mexican American culture is that of elders' ordering young men and women to establish obedience and male dominance. The husband represents authority and the wife-mother maintains a role of complete devotion to her husband and children. Role differentiation is taught implicitly and explicitly from infancy.

    Background: Polybrominated diphenyl ethers (PBDE), which are used as flame retardants, have been found to be higher in residents of California than of other parts of the United States. Objectives: We aimed to investigate the role of immigration to California on PBDE levels in Latino children. Methods: We compared serum PBDE concentrations in a population of first-generation Mexican-American 7-year-old children (n = 264), who were born and raised in California [Center for Health Analysis of Mothers and Children of Salinas (CHAMACOS) study], with 5-year-old Mexican children (n = 283), who were raised in the states in Mexico where most CHAMACOS mothers had originated (Proyecto Mariposa). Results: On average, PBDE serum concentrations in the California Mexican-American children were three times higher than their mothers’ levels during pregnancy and seven times higher than concentrations in the children living in Mexico. The PBDE serum concentrations were higher in the Mexican-American children regardless of length of time their mother had resided in California or the duration of the child’s breast-feeding. These data suggest that PBDE serum concentrations in these children resulted primarily from postnatal exposure. Conclusions: Latino children living in California have much higher PBDE serum levels than their Mexican counterparts. Given the growing evidence documenting potential health effects of PBDE exposure, the levels in young children noted in this study potentially present a major public health challenge, especially in California. In addition, as PBDEs are being phased out and replaced by other flame retardants, the health consequences of these chemical replacements should be investigated and weighed against their purported fire safety benefits.

    Background The study of body composition in specific populations by techniques such as bio-impedance analysis (BIA) requires validation based on standard reference methods. The aim of this study was to develop and cross-validate a predictive equation for bioelectrical impedance using air displacement plethysmography (ADP) as standard method to measure body composition in Mexican adult men and women. Methods This study included 155 male and female subjects from northern Mexico, 20–50 years of age, from low, middle, and upper income levels. Body composition was measured by ADP. Body weight (BW, kg) and height (Ht, cm) were obtained by standard anthropometric techniques. Resistance, R (ohms) and reactance, Xc (ohms) were also measured. A random-split method was used to obtain two samples: one was used to derive the equation by the "all possible regressions" procedure and was cross-validated in the other sample to test predicted versus measured values of fat-free mass (FFM). Results and Discussion The final model was: FFM (kg) = 0.7374 * (Ht2 /R) + 0.1763 * (BW) - 0.1773 * (Age) + 0.1198 * (Xc) - 2.4658. R2 was 0.97; the square root of the mean square error (SRMSE) was 1.99 kg, and the pure error (PE) was 2.96. There was no difference between FFM predicted by the new equation (48.57 ± 10.9 kg) and that measured by ADP (48.43 ± 11.3 kg). The new equation did not differ from the line of identity, had a high R2 and a low SRMSE, and showed no significant bias (0.87 ± 2.84 kg). Conclusion The new bioelectrical impedance equation based on the two-compartment model (2C) was accurate, precise, and free of bias. This equation can be used to assess body composition and nutritional status in populations similar in anthropometric and physical characteristics to this sample. PMID:17697388

    Objective To examine the influence of neighbourhood socioeconomic position (NSEP) on development of diabetes over time. Design A longitudinal cohort study. Setting The data reported were from the Sacramento Area Latino Study on Aging, a longitudinal study of the health of 1789 older Latinos. Participants Community-dwelling older Mexican Americans residing in the Sacramento Metropolitan Statistical Area. Main outcome Multistate Markov regression were used to model transitions through four possible states over time: 1=normal; 2=pre-diabetic; 3=diabetic; and 4=death without diabetes. Results At baseline, nearly 50% were non-diabetic, 17.5% were pre-diabetic and nearly 33% were diabetic. At the end of follow-up, there were a total of 824 people with type 2 diabetes. In a fully adjusted MSM regression model, among non-diabetics, higher NSEP was not associated with a transition to pre-diabetes. Among non-diabetics, higher NSEP was associated with an increased risk of diabetes (HR=1.66, 95% CI 1.14 to 2.42) and decreased risk of death without diabetes (HR: 0.56, 95% CI 0.33 to 0.96). Among pre-diabetics, higher NSEP was significantly associated with a transition to non-diabetic status (HR: 1.22, 95% CI 0.99 to 1.50). Adjusting for BMI, age, education, physical activity, smoking, alcohol consumption, medical insurance and nativity did not affect this relationship. Conclusions Our findings show that high NSEP poses higher risk of progression from normal to diabetes compared with a lower risk of death without diabetes. This work presents a possibility that these associations are modified by nativity or culture. PMID:27515749

    Congress has given NASA and the science community a reality check. The tight and ever shrinking budgets are trimming the fat from many space science programs. No longer can a Principal Investigator (PI) afford to waste development dollars on re-inventing spacecraft controllers, experiment/payload controllers, ground control systems, or test sets. Inheritance of the Ground Support Equipment (GSE) from one program to another is not a significant re-use of technology to develop a science mission in these times. Reduction of operational staff and highly autonomous experiments are needed to reduce the sustaining cost of a mission. The re-use of an infrastructure from one program to another is needed to truly attain the cost and time savings required. Interface and Control Systems, Inc. (ICS) has a long history of re-usable software. Navy, Air Force, and NASA programs have benefited from the re-use of a common control system from program to program. Several standardization efforts in the AIAA have adopted the Spacecraft Command Language (SCL) architecture as a point solution to satisfy requirements for re-use and autonomy. The Environmental Research Institute of Michigan (ERIM) has been a long-standing customer of ICS and are working on their 4th generation system using SCL. Much of the hardware and software infrastructure has been re-used from mission to mission with little cost for re-hosting a new experiment. The same software infrastructure has successfully been used on Clementine, and an end-to-end system is being deployed for the Far Ultraviolet Spectroscopic Explorer (FUSE) for Johns Hopkins University. A case study of the ERIM programs, Clementine and FUSE will be detailed in this paper.

    Background According to the Centers for Disease Control and Prevention, Hispanic breastfeeding mothers begin early formula supplementation at higher rates than other ethnic groups, which can lead to shorter breastfeeding duration and decreased exclusive breastfeeding. Acculturation, the process of adopting beliefs and behaviors of another culture, appears to influence breastfeeding practices of Hispanic women in the United States. Little is known about Mexican American mothers’ formula use and exclusive breastfeeding within the context of acculturation. Objective Our study identified perceived benefits and barriers to exclusive breastfeeding and levels of acculturation among Mexican American women living in a Midwestern city. Methods We used a qualitative descriptive design integrating Pender’s Health Promotion Model concepts. Individual interviews were conducted in English or Spanish (N = 21). The revised Acculturation Rating Scale for Mexican Americans was used to examine acculturation levels. Results Acculturation scores indicated that the majority (66%) of the sample was “very Mexican oriented.” Most women exclusively breastfed, with a few using early supplementation for “insufficient milk production.” Three themes emerged: (1) It is natural that a woman give life and also provide the best food for her baby; (2) Breastfeeding is ultimately a woman’s decision but is influenced by tradition, guidance, and encouragement; and (3) Breast milk is superior but life circumstances can challenge one’s ability to breastfeed. Conclusion Strong familial/cultural traditions supported and normalized breastfeeding. Barriers to exclusive breastfeeding were similar to breastfeeding women in general, in the United States. Findings support the need for culturally competent and individualized lactation care. PMID:26289059

  20. Dental variation among four prehispanic Mexican populations.

    PubMed

    Haydenblit, R

    1996-06-01

    In this paper, the dental morphology of prehispanic Meso-american populations is described, compared, and examined within the context of New World dental variation. Twenty-eight morphological dental traits were studied and compared in four samples of prehispanic Mexican populations. After eliminating intra- and interobserver error, the dental morphological characteristics observed show evidence of heterogeneity among the populations. In particular, the oldest population, Tlatilco (1300-800 BC), was significantly different from the other three groups, Cuicuilco (800-100 BC), Monte Albán (500 BC-700 AD) and Cholula (550-750 AD). When the four samples were compared to other Mongoloid populations, either univariately or multivariately, it was observed that the Mexican groups did not follow a strict Sinodont (characteristic of Northeast Asia)/Sundadont (characteristic of Southeast Asia) classification (Turner [1979] Am. J. Phys. Anthropol. 51:619-636). From the traits examined, 27% presented frequencies consistent with Sinodont variation, while 73% of the traits showed similar incidence to Southeast Asian groups. Multivariately, the Mexican populations were found to fit an overall Sundadont classification. These results indicate that there is more dental morphological variation among American Indian populations than previously shown.

    Mexican adolescents continue to be at increased risk for HIV infection due to inconsistent condom use. The purpose of this study was to identify predictors of condom use intentions and condom use among Mexican adolescents who participated in a randomized control trial designed to test a sexual-risk reduction intervention. Data from sexually active adolescents 17 to 21 years (n = 157) of age who were assigned to the control group were analyzed 48 months post intervention. Regression analysis showed that positive attitudes toward condoms, subjective norms, and control beliefs significantly explained intention to use condoms (R2 = .75, p < .001). Attitudes toward condoms (β = .67, p < .001), technical skills (β = .13, p = .01), and condom use self-efficacy (β = .24, p < .001) were significant predictors of condom use intention. Compared to those who inconsistently used condoms, adolescents who used condoms consistently had greater intention to use condoms and greater impulse control. Findings suggest that attitudes and control beliefs should be further explored with Mexican adolescents in order to support consistent condom use. PMID:20949835

    2013-05-01

    The neuraminidase (NA) epitope from the Mexican AH1N1 influenza virus was identified by using sequences registered at the GenBank during the peak of a pandemic (from April 2009 to October 2010). First, NA protein sequences were submitted for multiple alignment analysis, and their three-dimensional models (3-D) were then built by using homology modeling. The most common sequence (denominated wild-type) and its mutants were submitted to linear and nonlinear epitope predictors, which included the major histocompatibility complex type II (MHC II) and B-cell peptides. The epitope prediction was in accordance with evolutionary behavior and some protein structural properties. The latter included a low NA mutation rate, NA 3-D surface exposure, and the presence of high hindrance side chain residues. After selecting the epitope, docking studies and molecular dynamics (MD) simulations were used to explore interactions between the epitope and MHC II. Afterward, several experimental assays were performed to validate the theoretical study by using antibodies from humans (infected by pandemic H1N1) and rabbits (epitope vaccination). The results show 119 complete sequences that were grouped into 28 protein sequences according to their identity (one wild-type and 27 representative mutants (1-5 mutations)). The predictors yielded several epitopes, with the best fit being the one located in the C-terminal region. Theoretical methods demonstrated that the selected epitope reached the P4, P6, P7, and P9 pockets of MHC II, whereas the experimental evidence indicates that the epitope is recognized by human antibodies and also by rabbit antibodies immunized with the peptide.

    2009-09-15

    This paper presents a complete methodology for the characterization of silver alloys used in modern coin production. Mexican coins with a nominal silver concentration from 10% to 99.99% were used in this study. Calibrated Glow Discharge Optical Emission Spectrometers were used to determine the chemical composition of the alloys as a function of the depth, while inductively coupled plasma was used to determine the total element composition in bulk. Scanning Electron Microscope was used to study the phase distributions in the different silver coins. According to Glow Discharge Optical Emission Spectrometers and inductively coupled plasma, the silver content found in the studied samples was consistently greater than that of the nominal silver content reported by the Mexican mint. This may lead to a review of the new methods of analysis used nowadays in contemporary coin minting. This result is very important because silver is increasing in value as metal and, considering the volume of production of silver coins, this may increase further as a consequence of a growing popular confidence in silver currency. In the case of silver studies, an advantage of the absence of silver detector in the Glow Discharge Optical Emission Spectrometers system is that it allows for the recalibration to have a better range of detection of other metals present in the alloys. A calibration curve using the copper content obtained by inductively coupled plasma (bulk) and Glow Discharge Optical Emission Spectrometers (depth profile) was performed. The relevance of control in modern silver coin minting was clarified, especially in minimizing the discrepancy between the nominal and the core fineness. The physical and chemical properties of the alloys studied are defined, revealing important variations in silver and copper contents. A new methodology and metrology for the control of coinage are suggested.

  6. Design and validation of a self-administered test to assess bullying (bull-M) in high school Mexicans: a pilot study

    PubMed Central

    2013-01-01

    Background Bullying (Bull) is a public health problem worldwide, and Mexico is not exempt. However, its epidemiology and early detection in our country is limited, in part, by the lack of validated tests to ensure the respondents’ anonymity. The aim of this study was to validate a self-administered test (Bull-M) for assessing Bull among high-school Mexicans. Methods Experts and school teachers from highly violent areas of Ciudad Juarez (Chihuahua, México), reported common Bull behaviors. Then, a 10-item test was developed based on twelve of these behaviors; the students’ and peers’ participation in Bull acts and in some somatic consequences in Bull victims with a 5-point Likert frequency scale. Validation criteria were: content (CV, judges); reliability [Cronbach’s alpha (CA), test-retest (spearman correlation, rs)]; construct [principal component (PCA), confirmatory factor (CFA), goodness-of-fit (GF) analysis]; and convergent (Bull-M vs. Bull-S test) validity. Results Bull-M showed good reliability (CA = 0.75, rs = 0.91; p < 0.001). Two factors were identified (PCA) and confirmed (CFA): “bullying me (victim)” and “bullying others (aggressor)”. GF indices were: Root mean square error of approximation (0.031), GF index (0.97), and normalized fit index (0.92). Bull-M was as good as Bull-S for measuring Bull prevalence. Conclusions Bull-M has a good reliability and convergent validity and a bi-modal factor structure for detecting Bull victims and aggressors; however, its external validity and sensitivity should be analyzed on a wider and different population.

    2009-12-01

    This study examines changes over time in ethnic affirmation/belonging and ethnic identity achievement, Spanish language use, English language use, Mexican/Mexican-American affiliation/identification and Anglo affiliation/identification in a sample of Mexican-American adolescents participating in a longitudinal study of juvenile offenders. The Multigroup Ethnic Identity Measure and the Acculturation Rating Scale for Mexican Americans-II were completed by the Mexican-American adolescents 7 times over a 3-year period. The findings from longitudinal growth modeling analyses and growth mixture modeling analyses indicate that there is heterogeneity in the initial scores and changes over time on these variables that are related to markers for the cultural qualities of the home environment (i.e., generational status and mother's most frequent language use). In contrast to expectations, marginalized or assimilated acculturation trajectories/types were not overrepresented in this sample of adolescent offenders. Implications for our understanding of the nature of acculturation and enculturation processes and the way these processes are studied are discussed.

    This article is a slide show discussion of demand-side management efforts by San Diego Gas and Electric as applied to a particular industry in their service area. The evolution of SDG&E`s rate structure is noted, from interruptible services rates to the present structure of variable time-of-use. For the case noted, this has resulted in a reduction of outages at the manufacturing facility and a 30% reduction in the cost per kwh to the user.

  19. The "Other White": Mexican Americans and the Impotency of Whiteness in the Segregation and Desegregation of Texan Public Schools

    2008-01-01

    This article analyzes the legal classification of Mexican Americans as "other white" as argued in a number of critical court cases that beginning in the 1930s up to the 1970s attempted to desegregate public schools in Texas. Since the Texas constitution declared school segregation as being only for "colored children," Mexican Americans in their…

  20. Strong Selection at MHC in Mexicans since Admixture

    Mexicans are a recent admixture of Amerindians, Europeans, and Africans. We performed local ancestry analysis of Mexican samples from two genome-wide association studies obtained from dbGaP, and discovered that at the MHC region Mexicans have excessive African ancestral alleles compared to the rest of the genome, which is the hallmark of recent selection for admixed samples. The estimated selection coefficients are 0.05 and 0.07 for two datasets, which put our finding among the strongest known selections observed in humans, namely, lactase selection in northern Europeans and sickle-cell trait in Africans. Using inaccurate Amerindian training samples was a major concern for the credibility of previously reported selection signals in Latinos. Taking advantage of the flexibility of our statistical model, we devised a model fitting technique that can learn Amerindian ancestral haplotype from the admixed samples, which allows us to infer local ancestries for Mexicans using only European and African training samples. The strong selection signal at the MHC remains without Amerindian training samples. Finally, we note that medical history studies suggest such a strong selection at MHC is plausible in Mexicans.

    The practice of neurocritical care encompasses multiple acute neurologic and neurosurgical diseases and requires detailed knowledge of neurology and critical care. This article presents 5 cases that illustrate just some of the conditions encountered in the daily practice of neurocritical care and exemplify some of the common diagnostic, therapeutic, and prognostic challenges facing the neurointensivist. Life-threatening medical complications after severe acute ischemic stroke, seizures and extreme agitation from autoimmune encephalitis, refractory seizures after subdural hemorrhage, neurologic and systemic complications related to aneurysmal subarachnoid hemorrhage, and status epilepticus after cardiac arrest are discussed in this article.

    The incidence of diabetic nephropathy (DN) is growing rapidly worldwide as a consequence of the rising prevalence of Type 2 diabetes mellitus (T2DM). Among U.S. ethnic groups, Mexican Americans have a disproportionately high incidence and prevalence of DN and associated end-stage renal disease (ESRD). In communities bordering Mexico, as many as 90% of Mexican American patients with ESRD also suffer from T2DM compared to only 50% of non-Hispanic Whites (NHW). Both socio-economic factors and genetic predisposition appear to have a strong influence on this association. In addition, certain pathogenetic and clinical features of T2DM and DN are different in Mexican Americans compared to NHW, raising questions as to whether the diagnostic and treatment strategies that are standard practice in the NHW patient population may not be applicable in Mexican Americans. This article reviews the epidemiology of DN in Mexican Americans, describes the pathophysiology and associated risk factors, and identifies gaps in our knowledge and understanding that needs to be addressed by future investigations.

    The use of hormonal therapies, including hormonal contraceptives (HC) and postmenopausal hormone replacement therapy (HRT) have been shown to influence breast cancer (BC) risk. However, the variations of these effects among populations and ethnic groups are not completely documented, especially among Hispanic women. We evaluated the association between HC and premenopausal BC risk, and between HRT and postmenopausal BC risk in Mexican women. Data from a Mexican multi-center population-based case–control study ofwomen aged 35 to 69 years were analysed. A total of 1000 cases and 1074 matched controls were recruited between 2004 and 2007. Information on hormonal therapy was collected through a structured questionnaire. Results were analysed using conditional logistic regression models. Overall, HC were used by 422/891 (47.3%) premenopausal women and HRT was used by 220/1117 (19.7%) postmenopausal women. For HC, odds ratios (ORs) for BC were 1.11 (95% confidence interval (CI): 0.82, 1.49) for current users and 1.68 (95% CI: 0.67, 4.21) for ever-users. No clear effect of duration of use was observed. For HRT, the OR for BC was significantly increased in ever users (OR: 1.45; 95% CI: 1.01, 2.08). A non-significant increased risk was observed for combined estrogen/progestin, (OR =  1.85; 95% CI: 0.84, 4.07) whereas no effect was observed for the use of estrogen alone (OR = 1.14; 95% CI: 0.68, 1.91). Our results indicate that, HC had a non-significant effect on the risk of pre-menopausal BC, but suggested that injected contraceptives may slightly increase the risk, whereas HRT had a significant effect on post-menopausal BC in this population. This study provides new information about the effects of HC and HRT on BC risk in a Mexican population, which may be of relevance for the population of Latin America as a whole. PMID:24260282

    Three microorganisms were assayed to evaluate the microbiological quality in the seawater at a resort on the Mexican Pacific coast, and to test for possible associations among the titers of the various bacteria, their possible correlations with environmental conditions, and with the location of potential wastewater outflows. Significant microorganism levels were found (at Caletilla beach, Hornos beach, and Papagayo beach, respectively: for Enterococcus 157, 153, and 149, for C. perfringens 35, 89, and 56, for S. aureus 244,137, and 279CFU/100ml), often in excess of the presently set guideline values. In general, bacterial titers were higher during rainy season than in dry season. For S. aureus, in both seasons, highest concentrations were found at 3pm, the time of highest tourist presence at the beaches. Our results argue for the use of these three microorganisms as part of a set of indicators in the routine microbiological evaluation of Mexican beachwaters.

  12. Ethical issues in case study publication: "making our case(s)" ethically.

    PubMed

    McCurdy, David B; Fitchett, George

    2011-01-01

    As chaplains develop richly detailed case studies for publication, ethical questions about case study construction and publication are emerging. Concerns about seeking patients' permission to publish material about them suggest additional questions and raise broad confidentiality and privacy issues. Confidentiality-related practices in health care and psychotherapy provide the most extensive guidance for chaplains, but healthcare chaplaincy has roots in religious and professional traditions with distinct notions of confidentiality that deserve consideration. Single case studies do not appear to be "research" requiring informed consent, yet their publication exposes patients to some risk of harm. Obtaining the patient's/"case study subject's" permission to publish, disguising non-essential information, and allowing the patient to review the case study can mitigate the risks. Striking a balance between protecting patients and providing sufficient detail to make case studies useful is a central ethical challenge of case study publication.

    Objectives Investigate the “salmon-bias” hypothesis, which posits that Mexicans in the U.S. return to Mexico due to poor health, as an explanation for the Hispanic health paradox in which Hispanics in the United States are healthier than might be expected from their socioeconomic status. Method Sample includes Mexicans age 50 or above living in the U.S. and Mexico from the 2003 Mexican Health and Aging Study and the 2004 Health and Retirement Study. Logistic regressions examine whether non-migrants or return migrants have different odds than immigrants of reporting a health outcome. Results The “salmon-bias” hypothesis holds for select health outcomes. However, non-migrants and return migrants have better health outcomes than immigrants on a variety of indicators. Discussion Overall, the results of this study do not support the salmon bias hypothesis; other explanations for the paradox could be explored. PMID:23264441

    One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61Z–year old male patient diagnosed with peritonitis. During surgery, a right adrenal tumor of 2 cm is discovered. The patient was referred to endocrinology. 6 months later the diameter of the tumor is 7 times bigger than the initial stage. It has no secretory phenotype, except for the small increase of serum aldosterone and the 24–h 17–ketosteroids. Open right adrenalectomy is performed and a cyst of 15 cm is removed. The evolution after surgery is good. The pathological exam reveals an adrenal cyst with calcifications and osteoid metaplasia. The immunohistochemistry showed a positive reaction for CD34 and ACT in the vessels and VIM in the stroma. The adrenal cysts are not frequent and represent a challenge regarding the preoperative diagnostic and surgical procedure of resection. The pathological exam highlights the major aspects.

    Bisulca, Christina

    The research presented in this dissertation covers three separate topics of conservation as defined by the National Science Foundation: 1) Materials Stabilization, Strengthening, Monitoring, and Repair; 2. Understanding Material Degradation and Aging; and 3) Materials and Structural Characterization of Cultural Heritage Objects (the 'technical study'). The first topic is addressed through a study to assess the consolidant tetraethoxysilane for the stabilization of alum treated wood. Falling under materials degradation studies is a study published in American Museum Novitates to understand how environmental conditions affect the aging of fossil resins from five different deposits. Two separate studies are included in technical study of cultural heritage objects which comprises the third research area of materials characterization. The first is a survey of red dyes used in Chinese paintings from the Ming Dynasty to the Early Republic (1364-1911). The second is a study of the pigments, dyes and binders used in Hawaiian barkcloth (kapa) from the 19th century.

  17. Why do Mexican Americans give birth to few low-birth-weight infants?

    PubMed

    Buekens, P; Notzon, F; Kotelchuck, M; Wilcox, A

    2000-08-15

    There are relatively few low-weight births among Mexican Americans, despite their socioeconomic disadvantages. Fewer low-birth-weight (LBW) births result when babies are heavier at term or when there are fewer preterm deliveries. The authors used 1994 US singleton livebirth birth certificates to compare Mexican Americans with non-Hispanic Whites. They found that the lower LBW rate among Mexican Americans (5.8%) compared with non-Hispanic Whites (6.1%) occurred because fewer small, preterm babies were born to Mexican Americans (3.4% vs. 3.9%). This result was obscured by two findings. First, the mean birth weight of Mexican American babies (3,343 g) was lower than that of non-Hispanic White babies (3,393 g). This finding again showed the independence of mean birth weight and LBW. Second, the overall preterm birth rate was higher among Mexican Americans (10.6%) than non-Hispanic Whites (9.3%). Our hypothesis is that this finding reflects errors in recorded gestational age, as illustrated by a strongly bimodal birth-weight distribution at young gestational ages for Mexican Americans. Further studies on the LBW paradox among Mexican Americans should thus focus on gestational age more than on birth weight.

    Recent modifications of the Civil Protection Law in Mexico include now specific mentions to space hazards and space weather phenomena. During the last few years, the UN has promoted international cooperation on Space Weather awareness, studies and monitoring. Internal and external conditions motivated the creation of a Space Weather Service in Mexico (SCIESMEX). The SCIESMEX (www.sciesmex.unam.mx) is operated by the Geophysics Institute at the National Autonomous University of Mexico (UNAM). The UNAM has the experience of operating several critical national services, including the National Seismological Service (SSN); besides that has a well established scientific group with expertise in space physics and solar- terrestrial phenomena. The SCIESMEX is also related with the recent creation of the Mexican Space Agency (AEM). The project combines a network of different ground instruments covering solar, interplanetary, geomagnetic, and ionospheric observations. The SCIESMEX has already in operation computing infrastructure running the web application, a virtual observatory and a high performance computing server to run numerical models. SCIESMEX participates in the International Space Environment Services (ISES) and in the Inter-progamme Coordination Team on Space Weather (ICTSW) of the Word Meteorological Organization (WMO).
