    We provide an overview of the role of adiposity, physical activity and diet in the risk for breast cancer in Mexican women. Lack of physical activity, diets high in carbohydrates and in glycemic load and low intake of folate and vitamin B12 have been shown to increase the risk of breast cancer in Mexican women, in particular postmenopausal breast cancer. Other dietary factors that may begin to play a more relevant role in breast cancer incidence in Mexico are alcohol intake and vitamin D stat...

    Of the 300 clinical files of pregnant women, 22 were associated with cancer plus pregnancy in 5 years. Of them 7 were excluded in the work. 15 patients with CaCu and pregnancy were studied in the Gineco-Obstetric Hospital No. 3 C.M. La Raza of the IMSS México City in a period since 1st of January 1988 to 31st December of 1992. Early menarchia and sexual life, take an important roll in the mexican women as predisponent factors, multideliver and tobacco too. The colposcopy with manage cervix biopsy is the election method of diagnosis, with 99.5% of confiability. In the 15 patients, the estirpe was epidermoid cancer in all of them. The diagnosis of pregnancy age made in the first and third trimester of gestation. Only in 3 patients (20%) were founded visible lesion, this rename the necessity of make detection of CaCu during the pregnancy, because we will can found the cases in preinvader stages or early invader, that cure highly, like the cases seen in this work. Stages preinvader and early invaders during the pregnancy are highly curatives. We concluded that they have worst prognosis of survival, aggressivity and early relapse in patients with pregnancy stage by stage. The last because in the Historical Literature review about this topic, there was statistical relevance about pregnancy in the women with CaCu, using our work for reference. CaCu does change his prognosis associated with the pregnancy.

    Biological wound dressings sterilized with gamma radiation, such as amnion and pig skin, are a reality in Mexico. These tissues are currently processed in the tissue bank and sterilized in the Gamma Industrial Irradiation Plant; both facilities belong to the Instituto Nacional de Investigaciones Nucleares (ININ) (National Institute of Nuclear Research). With the strong support of the International Atomic Energy Agency, the bank was established at the ININ and the Mexican Ministry of Health issued its sanitary license on July 7, 1999. The Quality Management System of the bank was certified by ISO 9001:2000 on August 1, 2003; the scope of the system is "Research, Development and Processing of Biological Tissues Sterilized with Gamma Radiation". At present, more than 150 patients from 16 hospitals have been successfully treated with these tissues. This paper presents a brief description of the tissue processing, as well as the present Mexican clinical experience with children and adult patients who underwent medical treatment with radiosterilized amnion and pig skin, used as biological wound dressings on burns and ocular surface disorders.

    The objetive of this study was to explore a bibliometric approach to quantitatively assess current research trends with regard to breast cancer in Mexico. Articles were analyzed by scientific output and research performances of individuals, institutes, and collaborative countries with Mexico. Data were retrieved from the Web of Science database from 2003 to 2012; this was searched using different terms related to breast cancer, including "breast cancer", "mammary ductal carcinoma" and "breast tumour". Data were then extracted from each file, transferred to Excel charts and visualised as diagrams. A total of 256 articles were retrieved. The institutions with the majority of publications were the National Autonomous University of Mexico (22.3%), the National Institute of Cancerology (21.9%), and Social Security Mexican Institute (20.3%); clinical observation studies were the dominant investigation type (64%), and the main types of research were metabolics (24.2%) and pathology (21.5%). This article demonstrates the usefulness of bibliometrics to address key evaluation questions and to establish priorities, define future areas of research, and develop breast cancer control strategies in Mexico.

    Breast cancer is the most common type of cancer worldwide. In response, breast cancer screening programs are becoming common around the world and public programs now serve millions of women worldwide. These programs are expensive, requiring many specialized radiologists to examine all images. Nevertheless, there is a lack of trained radiologists in many countries as in Mexico, which is a barrier towards decreasing breast cancer mortality, pointing at the need of a triaging system that prioritizes high risk cases for prompt interpretation. Therefore we explored in an image database of Mexican patients whether high risk cases can be distinguished using image features. We collected a set of 200 digital screening mammography cases from a hospital in Mexico, and assigned low or high risk labels according to its BIRADS score. Breast tissue segmentation was performed using an automatic procedure. Image features were obtained considering only the segmented region on each view and comparing the bilateral di erences of the obtained features. Predictive combinations of features were chosen using a genetic algorithms based feature selection procedure. The best model found was able to classify low-risk and high-risk cases with an area under the ROC curve of 0.88 on a 150-fold cross-validation test. The features selected were associated to the differences of signal distribution and tissue shape on bilateral views. The model found can be used to automatically identify high risk cases and trigger the necessary measures to provide prompt treatment.

  7. Perceptions and Experiences of Human Papillomavirus (HPV Infection and Testing among Low-Income Mexican Women.

    Full Text Available HPV infection causes cervical cancer, a major contributor to morbidity and mortality among low-income Mexican women. Human papillomavirus (HPV DNA testing is now a primary screening strategy in Mexico's early cervical cancer detection program (ECDP. Research on Mexican women's perceptions of HPV and testing is necessary for establishing culturally appropriate protocols and educational materials. Here, we explore perceptions about HPV and HPV-related risk factors among low-income Mexican ECDP participants.We conducted semi-structured interviews with 24 ECDP participants from two primary care health clinics in Michoacán state, Mexico. Interviews addressed women's understandings of and experiences with HPV and HPV testing. Analysis was inductive and guided by the Health Belief Model with a focus on gender.Women's confusion about HPV and HPV screening caused emotional distress. They understood HPV to be a serious disease that would always cause severe symptoms, often characterizing it as analogous to HIV or inevitably carcinogenic. Women also attributed it to men's sexual behaviors, specifically infidelity and poor hygiene. Women described both sexes' desire for sex as natural but understood men's negative practices of masculinity, like infidelity, as the causes of women's HPV infection. Some women believed dirty public bathrooms or heredity could also cause HPV transmission.These results are consistent with prior findings that geographically and economically diverse populations lack clear understandings of the nature, causes, or symptoms of HPV, even among those receiving HPV testing. Our findings also reveal that local cultural discourse relating to masculinity, along with failure to provide sufficient education to low-income and indigenous-language speaking patients, exacerbate women's negative emotions surrounding HPV testing. While negative emotions did not deter women from seeking testing, they could be ameliorated with better health

    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 fruits (p = 0.02). Ethnic differences in diet were also observed: Mexican Americans consumed less total fat (p fruits (p lung cancer risk (p 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.

    This study examined causal attribution beliefs about breast cancer and the influence that these beliefs exert on health behavior change among breast cancer survivors (BCS). Focus groups with Chinese (n = 21), Korean (n = 11), and Mexican American (n = 9) BCS recruited through community- and hospital-based support groups were conducted. Interviews were audio-recorded, transcribed verbatim, and translated into English for thematic content analysis. Three themes concerning beliefs about breast cancer cause common to all three groups included (a) stress, (b) diet, and (c) fatalism. Causal beliefs corresponded to behavioral changes with women describing efforts to improve their diet and manage their stress. Ethnic minority BCS adhere to beliefs about what caused their cancer that influence their health behaviors. Providing quality health care to ethnically diverse cancer survivors requires cultural sensitivity to patients' beliefs about the causes of their cancer and awareness of how beliefs influence patients' health behaviors post diagnosis.

    Full Text Available Cervical cancer affects millions of Americans, but the rate for cervical cancer in the Mexican American is approximately twice that for non-Mexican Americans. The etiologies of cervical cancer are still not fully understood. A number of somatic mutations, including several copy number alterations (CNAs, have been identified in the pathogenesis of cervical carcinomas in non-Mexican Americans. Thus, the purpose of this study was to investigate CNAs in association with cervical cancer in the Mexican American population. We conducted a pilot study of genome-wide CNA analysis using 2.5 million markers in four diagnostic groups: reference (n = 125, low grade dysplasia (cervical intraepithelial neoplasia (CIN-I, n = 4, high grade dysplasia (CIN-II and -III, n = 5 and invasive carcinoma (squamous cell carcinoma (SCC, n = 5 followed by data analyses using Partek. We observed a statistically-significant difference of CNA burden between case and reference groups of different sizes (>100 kb, 10–100 kb and 1–10 kb of CNAs that included deletions and amplifications, e.g., a statistically-significant difference of >100 kb deletions was observed between the reference (6.6% and pre-cancer and cancer (91.3% groups. Recurrent aberrations of 98 CNA regions were also identified in cases only. However, none of the CNAs have an impact on cancer progression. A total of 32 CNA regions identified contained tumor suppressor genes and oncogenes. Moreover, the pathway analysis revealed endometrial cancer and estrogen signaling pathways associated with this cancer (p < 0.05 using Kyoto Encyclopedia of Genes and Genomes (KEGG. This is the first report of CNAs identified for cervical cancer in the U.S. Latino population using high density markers. We are aware of the small sample size in the study. Thus, additional studies with a larger sample are needed to confirm the current findings.

    Huntington's disease (HD) is an autosomal dominant progressive, disabling neurodegenerative disorder, for which there is no effective treatment. Predictive testing (PT) for this illness began in 1986 and by 1993 it became more precise after cloning of the gene and the discovery of a CAG repeat expansion as the underlying cause. The objective of this paper is to illustrate the implementation and results of a PT program in a group of at-risk Mexican individuals with 12 years of follow-up. Our PT program conforms to the guidelines proposed by the International Huntington Association and the HD Working group of the World Federation of Neurology. Seventy-five individuals requested the testing, four of them did not fulfill the inclusion criteria, and five abandoned the program voluntarily before receiving the test results. Therefore, 66 results were delivered to 41 noncarriers and 25 mutation carriers. We did not have any catastrophic event, but 4 individuals with normal results and 11 mutation carriers were depressed. Even if this is a small sample, it is the first report of PT in a Latin-American population in which we have been faced with the same problems referred to in larger series.

    The impact of Mexican gastrointestinal research worldwide is limited and the outcome of the best research papers awarded by the Asociación Mexicana de Gastroenterología (AMG) is unknown. The objective of this study was to analyze the publication pattern of the research work, awarded by the AMG and their impact in international journals. The abstracts accepted for the annual meeting of the AMG from 1998 to 2006 were reviewed. Those presented in a plenary session or awarded were included. Their abstracts were searched in electronic databases. When not found, the main author was contacted by e-mail. In those papers published in a journal with an impact factor, the times it was cited were assessed. 35 abstracts were identified, mainly in gastroenterology (57.1%) and hepatology (34.3). Only in 5.7% (n=2) some of the authors were members of the governing board of AMG. The awarded institutions were Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (48.6%), Universities (Universidad Autónoma de Nuevo León, Universidad Nacional Autónoma de México and the Benemérita Universidad Autónoma de Puebla) (31.4%), Instituto Mexicano del Seguro Social (8.6%), Fundación Clínica Médica Sur (5.7%), Hospital Juárez (2.9%), Private hospital (2.9%). Most of the papers were published within a year (73.7%). Only 2 papers had more than 10 citations in another international journal with impact factor, with a median for all paper of 5 citations (0-45). Considering all institutions, the rate of publication is 48%. Only half of the awarded works were published and mainly in journals of local distribution. The impact of these studies worldwide is limited.

    Full Text Available INTRODUCTION: In Mexico, breast cancer (BC is one of the main causes of cancer deaths in women, with increasing incidence and mortality in recent years. Therefore, the aim of the study is identify possible risk factors related to BC. METHODS: An epidemiological study of hospital cases of BC and controls with cervical uterine cancer (CUCA was carried out at eight third level concentration hospitals in Mexico City. The total of 353 incident cases of BC and 630 controls with CUCA were identified among women younger than 75 years who had been residents of the metropolitan area of Mexico City for at least one year. Diagnosis was confirmed histologically in both groups. Variables were analyzed according to biological and statistical plausibility criteria. Univariate, bivariate and multivariate analyses were carried out. Cases and controls were stratified according to the menopausal hormonal status (pre and post menopause. RESULTS: The factors associated with BC were: higher socioeconomic level (OR= 2.77; 95%CI = 1.77 - 4.35; early menarche (OR= 1.32; 95%CI= 0.88 - 2.00; old age at first pregnancy (>31 years: OR= 5.49; 95%CI= 2.16 - 13.98 and a family history of BC (OR= 4.76; 95% CI= 2.10 - 10.79. In contrast, an increase in the duration of the breastfeeding period was a protective factor (>25 months: OR= 0.38; 95%CI= 0.20 - 0.70. CONCLUSIONS: This study contributes to the identification of risk factors for BC described in the international literature, in the population of Mexican women. Breastfeeding appears to play an important role in protecting women from BC. Because of changes in women`s lifestyles, lactation is decreasing in Mexico, and young women tend not to breastfeed or to shorten the duration of lactation.

    Full Text Available Objective. To estimate the annual cost of the National Cervical Cancer Screening Program (CCSP of the Mexican Institute of Social Security (IMSS. Materials and methods. This cost analysis examined regional coverage rates reported by IMSS. We estimated the number of cytology, colposcopy, biopsy and pathology evaluations, as well as the diagnostic test and treatment costs for cervical intraepithelial neoplasia grade II and III (CIN 2/3 and cervical cancer. Diagnostic test costs were estimated using a micro-costing technique. Sensitivity analyses were performed. Results. The cost to perform 2.7 million cytology tests was nearly 38 million dollars, which represents 26.1% of the total program cost (145.4 million. False negatives account for nearly 43% of the program costs. Conclusion. The low sensitivity of the cytology test generates high rates of false negatives, which results in high institutional costs from the treatment of undetected cervical cancer cases.

    Metastatic breast cancer as initial onset represents between 20 and 30 % of cases and is considered an incurable disease. The goal of its treatment is palliative, looking for increasing the survival while reducing the symptoms. Maintenance chemotherapy studies for metastatic breast cancer have demonstrated to prolong the progression-free survival, with unclear results in terms of overall survival. The main objectives of our study were the progression-free survival and overall survival in patients with recurring or metastatic breast cancer treated with capecitabine in the maintenance chemotherapy setting compared with patients not receiving maintenance chemotherapy. As secondary objectives, the frequency of dose-limiting toxicities and response rate were determined. A non-probabilistic sampling was used, through expert selection of patients from the recurring/metastatic breast cancer survey cared within the period from January 1, 2007, to December 21, 2012. A total of 77 patients were included. Clinical data of advanced/recurrent breast cancer patients that were treated with capecitabine were recorded. The study achieved its primary objective, since the progression-free survival was prolonged for the maintenance therapy group: 6.6 versus 18.1 months, p Siglo XXI Oncology Hospital extends the overall survival and progression-free survival with a good toxicity profile.

    Full Text Available OBJECTIVE: To investigate the association between family history (FH of neoplasia, gyneco-obstetric factors and breast cancer (BC in a case--control study. In cases, to analyze those variables in relation with early onset of BC, the manner of detection (self-examination, prompted by pain, or casual, the size of tumor, and the elapsed time to seek medical attention. MATERIAL AND METHODS: Data from 151 prevalent BC cases and 235 age-matched controls were analyzed by multiple logistic regression, to assess the influence of BC risk factors. RESULTS: Ten per cent of patients and 1% of controls had first-degree relatives (FDR with BC. Family history of FDR with BC (OR, 11.2; 95% CI 2.42-51.92 or with gastric or pancreatic cancer (OR, 17.7; 95% CI 2.2-142.6 was associated with BC risk. Breastfeeding at or under 25 years of age was protective against BC (OR, 0.40; 95% CI 0.24-0.66. The manner of tumor detection did not influence its size at the time of diagnosis. CONCLUSIONS: Our study confirms that FH of BC and/or of gastric or pancreatic carcinoma are risk factors for BC, while lactation at 25 years of age or earlier is protective.

    Breast cancer is associated to estrogen exposure. Allelic variants involved in estrogen metabolism might change the risk of developing this neoplasia. We examined the potential association of breast cancer risk in Mexican women with the polymorphisms CYP1A1 rs1048943, CYP1B1 rs1056836, COMT rs4680, GSTP1 rs1695, GSTT1 null and GSTM1 null which are involved in estrogen metabolism pathway. This study included 150 cases and 150 controls. A significant association was observed between, CYP1A1 rs1048943 (OR = 1.95, C.I. 1.13-3.36) and GSTP1 rs1695 (OR = 2.39, C.I. 1.24-4.24) polymorphisms with the risk of breast cancer. This risk was increased when the women were stratified according to their menopausal status. The results show that breast cancer risk significantly increases in women with 3-6 risk polymorphisms (OR = 3.75, C.I. 1.44-9.74).

    Rates of breast cancer (BC) have increased in Mexico, with the highest incidence and mortality rates observed in the northern Mexican states. This study aimed to describe the BC knowledge, attitudes and screening practices among Mexican women with and without a family history of BC residing along the Mexico-US border, and identify factors associated with screening behaviors. One hundred and twenty eight Mexican women aged 40 and older completed an interviewer-administered questionnaire on sociodemographic characteristics, knowledge, family history, and screening practices. There were no significant differences between Mexican women with and without a family history. Over 60% of women in both groups had never had a mammogram/breast ultrasound, and more than 50% had never obtained a clinical breast exam. Age, marital status, insurance, and breast cancer knowledge significantly influenced BC screening behaviors among Mexican women. Further research is needed to examine other key factors associated with screening utilization, in effort of improving BC rates.

    The effectiveness at the individual and community level of an educational intervention to increase cervical cancer screening self-efficacy among semi-urban Mexican women was evaluated and changes in reported community barriers were measured after the intervention was implemented. The educational intervention was evaluated with a quasi-experimental pre-test/post-test design and a control group, based on the Integrative Model of Behavior Prediction and AMIGAS project materials. For the intervention group, increased self-efficacy increased requests to obtain a Pap (p system affect the women's perceived ability to get a Pap. Better care for users is needed to increase consistent use of the test. The study shows the importance of using culturally adapted, multilevel, comprehensive interventions to achieve successful results in target populations.

    Breast cancer is the main cause of cancer deaths for Hispanic women. This study analyzes the role of functional health literacy on mammography screening behavior and adherence of Hispanic women. Survey data from 722 Mexican American women age 40 and over residing in the Lower Rio Grande Valley of Texas in 2008 were used to estimate logistic regression models to assess the role of functional health literacy on mammography screening behavior and adherence. About 51% of survey respondents had a functional health literacy level deemed as inadequate or marginally functional. After adjusting for other factors, women with adequate health literacy levels were more likely to report to have ever had a mammogram (odds ratio [OR] = 2.92; 95% confidence interval [CI] = 1.62-5.28), to have had a mammogram within the last 2 years (OR = 1.70; 95% CI = 1.14-2.53) or to have had one within the last year (OR = 2.30; 95% CI = 1.54-3.43), compared to women with inadequate or marginally adequate functional health literacy levels. Inadequate/marginal functional health literacy is strongly associated with lower mammography screening. Large improvements in breast cancer control in this population may come from either basic advances in health literacy or by tailored approaches to help women with low literacy navigate local health care systems.

    Full Text Available We provide an overview of the role of adiposity, physical activity and diet in the risk for breast cancer in Mexican women. Lack of physical activity, diets high in carbohydrates and in glycemic load and low intake of folate and vitamin B12 have been shown to increase the risk of breast cancer in Mexican women, in particular postmenopausal breast cancer. Other dietary factors that may begin to play a more relevant role in breast cancer incidence in Mexico are alcohol intake and vitamin D status. Recommendations to maintain a healthy weight, practice moderate physical activity, decrease intake of rapidly absorbed carbohydrates and increase consumption of fruits and vegetables could have an important impact on the epidemic of breast cancer in Mexico.Se proporciona una revisión general del papel de la adiposidad, la actividad física y la dieta sobre el riesgo de cáncer de mama en mujeres mexicanas. La falta de actividad física, una dieta alta en hidratos de carbono y en carga glicémica y la baja ingesta de ácido fólico y vitamina B12 se han relacionado con un aumento en el riesgo de cáncer de mama en mujeres mexicanas, sobre todo en mujeres posmenopáusicas. Otros factores dietéticos que han tenido un papel más relevante en la incidencia de cáncer de mama en México son la ingesta de alcohol y las concentraciones de vitamina D. Las recomendaciones sobre cómo mantener un peso saludable, realizar actividad física moderada, disminuir la ingesta de hidratos de carbono de absorción rápida e incrementar el consumo de frutas y verduras podrían tener un impacto importante en la disminución de la epidemia de cáncer de mama en México.

    Breast cancer (BC) is considered a global public health problem, and is the most frequently type diagnosed in Mexican women. Therefore, it is important to study the risk factors associated to this neoplasia in order to establish prevention strategies. The aim of this study was to evaluate the effect of hormonal contraceptives and hormone therapy (HT) use and period of use, breastfeeding practice, abdominal obesity and weight gain in adulthood, on the risk of BC in adult women from Northwest Mexico. This was a case-control study that included 162 women (81 cases and 81 controls). A sociodemographic and health questionnaire, and a survey history of body weight were applied to participants. Measurements of body weight, height and waist circumference were performed. To assess the association between BC risk and exposing factors, a multivariate logistic regression model was used. Average age of cases and controls were 51.8 ± 11.7 and 51.4 ± 11.3 years, respectively. No significant association was found between the use and period of use of hormonal contraceptives and HT with the risk of BC. The practice of breastfeeding (OR=0.34, 95%CI: 0.12- 0.92) and the time of exclusive breastfeeding (OR=0.64, 95%CI: 0.42-0.97; crude) were protective against the risk of BC. Abdominal obesity (OR=0.93, 95%CI: 0.90-0.97) and weight gain in early adulthood (OR=0.90, 95%CI: 0.85-0.95) were inversely associated to the risk of BC. In conclusion, the practice of breastfeeding may help prevent BC in Mexican women.

    Full Text Available Aims. KiSS1 is a metastasis suppressor gene associated with inhibition of cellular chemotaxis and invasion attenuating the metastasis in melanoma and breast cancer cell lines. Along the KiSS-1 gene at least 294 SNPs have been described; however the association of these polymorphisms as genetic markers for metastasis in breast cancer studies has not been investigated. Here we describe two simple PCR-RFLPs protocols to identify the rs5780218 (9DelT and the rs12998 (E20K KiSS1 polymorphisms and the allelic, genotypic, and haplotypic frequencies in Mexican general population (GP and patients with benign breast disease (BBD or breast cancer (BC. Results. The rs5780218 polymorphism was individually associated with breast cancer (P=0.0332 and the rs12998 polymorphism shows statistically significant differences when GP versus case (BC and BBD groups were compared (P<0.0001. The H1 Haplotype (G/- occurred more frequently in BC group (0.4256 whereas H2 haplotype (G/T was the most prevalent in BBD group (0.4674. Conclusions. Our data indicated that the rs5780218 polymorphism individually confers susceptibility for development of breast cancer in Mexican population and a possible role as a genetic marker in breast cancer metastasis for H1 haplotype (Wt/variant in KiSS1 gene must be analyzed in other populations.

    Youth's experiences with romantic relationships during adolescence and young adulthood have far reaching implications for future relationships, health, and well-being; yet, although scholars have examined potential peer and parent influences, we know little about the role of siblings in youth's romantic relationships. Accordingly, this study examined the prospective longitudinal links between Mexican-origin older and younger siblings' romantic relationship experiences and variation by sibling structural and relationship characteristics (i.e., sibling age and gender similarity, younger siblings' modeling) and cultural values (i.e., younger siblings' familism values). Data from 246 Mexican-origin families with older (M = 20.65 years; SD = 1.57; 50 % female) and younger (M = 17.72 years; SD = .57; 51 % female) siblings were used to examine the likelihood of younger siblings' involvement in dating relationships, sexual relations, cohabitation, and engagement/marriage with probit path analyses. Findings revealed older siblings' reports of involvement in a dating relationship, cohabitation, and engagement/marriage predicted younger siblings' relationship experiences over a 2-year period. These links were moderated by sibling age spacing, younger siblings' reports of modeling and familism values. Our findings suggest the significance of social learning dynamics as well as relational and cultural contexts in understanding the links between older and younger siblings' romantic relationship experiences among Mexican-origin youth.

    The aim of this study was to validate the Mexican-Spanish version of The European Organization for Research and Treatment of Cancer (EORTC) QLQ-BR23 questionnaire. The translation procedure followed EORTC guidelines. QLQ-C30 and QLQ-BR23 instruments were completed by Mexican women with breast cancer, attending a teaching referral cancer centre from February 2009 to January 2010. Patients were divided in two groups: (1) Patients with early stage of breast cancer; and (2) Patients with locally advanced breast cancer (LABC). Reliability and validity tests were performed, and validity over time (responsiveness) was conducted in a subset of patients. Two hundred and thirty-four women (mean age, 52.3 years) completed both questionnaires. Convergent and divergent validity was adequate. Cronbach's alpha of all multi-item scales showed values ≥0.7 except for Cognitive and Breast symptoms scales (0.52 and 0.65 respectively). Patients with early stages (n= 77) showed better functional scores and lower symptoms scores than patients with LABC (n= 157). Score means variation after responsiveness analysis demonstrated high sensitivity to change after breast cancer surgery. The Mexican-Spanish version of the EORTC QLQ-BR23 questionnaire is a valid and suitable instrument to estimate HRQL in patients with breast cancer.

    Various guidelines recommend that women with triple-negative breast cancer should be tested for BRCA1 mutations, but the prevalence of mutations may vary with ethnic group and with geographic region, and the optimal cutoff age for testing has not been established. We estimated the frequencies of BRCA1 and BRCA2 (BRCA) mutations among 190 women with triple-negative breast cancer, unselected for family history, diagnosed at age 50 or less at a single hospital in Mexico City. Patients were screened for 115 recurrent BRCA mutations, which have been reported previously in women of Hispanic origin, including a common large rearrangement Mexican founder mutation (BRCA1 ex9-12del). A BRCA mutation was detected in 44 of 190 patients with triple-negative breast cancer (23 %). Forty-three mutations were found in BRCA1 and one mutation was found in BRCA2. Seven different mutations accounted for 39 patients (89 % of the total mutations). The Mexican founder mutation (BRCA1 ex9-12del) was found 18 times and accounted for 41 % of all mutations detected. There is a high prevalence of BRCA1 mutations among young triple-negative breast cancer patients in Mexico. Women with triple-negative breast cancer in Mexico should be screened for mutations in BRCA1.

    Full Text Available Monitoring and evaluation (M&E have gradually become important and regular components of the policy-making process in Mexico since, and even before, the World Health Organization (WHO Commission on Social Determinants of Health (CSDH called for interventions and policies aimed at tackling the social determinants of health (SDH. This paper presents two case studies to show how public policies addressing the SDH have been monitored and evaluated in Mexico using reliable, valid, and complete information, which is not regularly available. Prospera, for example, evaluated programs seeking to improve the living conditions of families in extreme poverty in terms of direct effects on health, nutrition, education and income. Monitoring of Prospera's implementation has also helped policy-makers identify windows of opportunity to improve the design and operation of the program. Seguro Popular has monitored the reduction of health inequalities and inequities evaluated the positive effects of providing financial protection to its target population. Useful and sound evidence of the impact of programs such as Progresa and Seguro Popular plus legal mandates, and a regulatory evaluation agency, the National Council for Social Development Policy Evaluation, have been fundamental to institutionalizing M&E in Mexico. The Mexican experience may provide useful lessons for other countries facing the challenge of institutionalizing the M&E of public policy processes to assess the effects of SDH as recommended by the WHO CSDH.

    A short CAG repeat length in the gene encoding for the androgen receptor (AR) has been associated with prostate cancer (PC) risk and aggressiveness. In Latino men, information on this association is scarce. Hence, the aim of this study was to evaluate this association in Mexican males. Using fragment analysis by capillary electrophoresis, we determined the number of CAG repeats-(CAG)n-in AR gene from 158 incident PC cases and 326 age-matched healthy controls (±5 years), residing in Mexico City, Mexico. According to Gleason scale and age at diagnosis, cases were classified as high (⩾7) and low grade (CAG repeat length than controls (18.6±2.2 vs 19.5±2.5; P=0.02). Lower number of CAG repeats (CAG)⩽19 were associated with a greater risk for early-onset PC (odds ratio: 2.31; 95% confidence interval: 1.14-4.69). CAG repeat length could increase the risk for sporadic and early-onset PC. The best cutoff point for identifying at-risk subjects was (CAG)19. However, further studies are necessary to replicate our findings in subjects with a family history of PC and also to evaluate the association between CAG repeats length and disease progression.

    Breast cancer is the most frequent malignancy affecting women worldwide. It has been suggested that infection by Epstein Barr Virus (EBV), Mouse Mammary Tumor Virus or a similar virus, MMTV-like virus (MMTV-LV), play a role in the etiology of the disease. However, studies looking at the presence of these viruses in breast cancer have produced conflicting results, and this possible association remains controversial. Here, we used polymerase chain reaction assay to screen specific sequences of EBV and MMTV-LV in 86 tumor and 65 adjacent tissues from Mexican women with breast cancer. Neither tumor samples nor adjacent tissue were positive for either virus in a first round PCR and only 4 tumor samples were EBV positive by a more sensitive nested PCR. Considering the study's statistical power, these results do not support the involvement of EBV and MMTV-LV in the etiology of breast cancer.

    This study explored how Chinese American, Korean American, and Mexican American women modify their health behaviors following breast cancer treatment and identified motivators and barriers that influence their changes. An exploratory, descriptive, qualitative study was undertaken using six focus groups. Discussions were transcribed and translated for content analysis. Significant differences among the ethnic groups were noted in the following health behavior practices which were most commonly stated as changed behaviors after a breast cancer diagnosis: 1) eating habits, 2) physical activity, 3) alternative medicine, 4) sleeping, 5) social activity, 6) weight control, and 7) alcohol consumption. Family, financial concerns, environment, and religious faith were commonly mentioned as motivators of and/or barriers to changes in health behaviors. Findings provide insight into different perspectives related to changes in health behaviors by ethnicity, which is critical for developing culturally tailored behavioral interventions to improve underserved breast cancer survivors' quality of life and to reduce health disparities.

Sociodemographic characteristics and clinical factors of 102 women with early BC were also evaluated; analysis of variance (ANOVA) was performed and a statistical significance of p < 0.05 was assumed. Most women were of reproductive age. Meaningful differences in QOL as a result of surgical treatment, in women receiving BCS compared with those receiving MRM, were limited to body image. We conclude that MRM and BCS are essentially equivalent choices in terms of QOL, with the exception of the impact on body image. In general, women who received BCS had a better perceived QOL.

    We investigated whether the MDR1 C3435T polymorphism is associated with fibrocystic changes (FCC), infiltrating ductal breast cancer (IDBC), and/or clinical-pathological features of IDBC in Mexican patients. Samples from women who received surgical treatment in 2007 at the Centro Médico de Occidente (México) were included in the analysis. Genotyping was performed by polymerase chain reaction-restricted fragment length polymorphisms in 64 paraffin-embedded breast samples with IDBC, 64 samples with FCC, and 183 peripheral blood samples of healthy females designated as the healthy group (HG). The frequency of the T allele was 41, 45, and 52% for the FCC, IDBC, and HG samples, respectively. Significant differences were only found between the FCC and HG samples [odds ratio (OR) = 0.64, 95% confidence interval (CI) = 0.43-0.96; P = 0.032]. The prevalence of the T/T genotype was 8, 13, and 24% for FCC, IDBC, and HG samples, respectively. Again, statistical differences were only found between FCC and HG samples for the T/T genotype (OR = 0.28, 95%CI = 0.106-0.77; P = 0.009). Although the T allele and the T/T genotype were less frequent in the IDBC group than in the HG, the differences were not significant. Furthermore, no associations were found between the C3435T polymorphism and clinical-pathological features of the IDBC group. Both the FCC and IDBC groups had a high frequency of the C allele relative to the HG in this sample of women from Western Mexico.

    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 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 worsening of the health status at an

    Introduction The progesterone receptor (PR) gene plays an important role in reproduction-related events. Data on polymorphisms in the PR gene have revealed associations with cancer, particularly for the Alu insertion polymorphism, which has been suggested to affect progesterone receptor function and contribute to tumor promotion in the mammary gland. Material and methods We examined the role of the Alu insertion polymorphism in the PR gene by comparing the genotypes of 209 healthy Mexican women with those of 481 Mexican women with breast cancer (BC). Results The genotype frequencies observed in the controls and BC patients were 0% and 4% for T2/T2 (Alu insertion), 16% and 21% for T1/T2, and 84% and 75% for T1/T1 (Alu deletion), respectively. The obtained odds ratio (OR) was 1.7, with a 95% confidence interval (95% CI) of 1.1–2.6, p = 0.009, for the T1/T2–T2/T2 genotypes. The association was also evident when the distributions of the T1/T2–T2/T2 genotypes in patients in the following categories were compared: obesity grade II (OR = 1.81, 95% CI: 1.03–3.18, p = 0.039) and the chemotherapy response (OR = 1.91, 95% CI: 1.27–3.067, p = 0.002). Conclusions The T1/T2–T2/T2 genotypes of the Alu insertion polymorphism in the PR gene are associated with BC susceptibility in the analyzed Mexican population. PMID:26170848

    Background and Aims The rs2981582 single nucleotide polymorphism in the Fibroblast Growth Factor Receptor 2 gene has been consistently associated with an increased risk of breast cancer. We evaluated the effect of rs2981582 polymorphism in the FGFR2 gene on the risk of breast cancer and its interaction with non-genetic risk factors. Methods A population based case control study was conducted in Mexico. Data from 687 cases and 907 controls were analyzed. Results The T allele of the rs2981582 polymorphism was associated with an increased risk of breast cancer (OR per allele =1.24, 95% CI 1.06 – 1.46). There was also an interaction between this polymorphism and alcohol consumption (p = 0.043); the effect of alcohol consumption on the risk of breast cancer varied according to the allelic variants of the rs2981582 polymorphism in the FGFR2 gene: OR = 3.97 (95% CI 2.10 – 7.49), OR = 2.01 (95% CI 1.23 − 3.29) and OR = 1.21 (95% CI 0.48 − 3.05) for genotypes CC, CT and TT, respectively. Conclusions This is the first study exploring the association between rs2981582 polymorphism in the FGFR2 gene and breast cancer risk in Mexican women. The interaction found may be of great public health interest, since alcohol consumption is a modifiable breast cancer risk factor. Therefore, replication of this finding is of foremost importance.

    Full Text Available Hereditary breast cancer comprises 10% of all breast cancers. The most prevalent genes causing this pathology are BRCA1 and BRCA2 (breast cancer early onset 1 and 2, which also predispose to other cancers. Despite the outstanding relevance of genetic screening of BRCA deleterious variants in patients with a history of familial cancer, this practice is not common in Latin American public institutions. In this work we assessed mutations in the entire exonic and splice-site regions of BRCA in 39 patients with breast and ovarian cancer and with familial history of breast cancer or with clinical features suggestive for BRCA mutations by massive parallel pyrosequencing. First we evaluated the method with controls and found 41-485 reads per sequence in BRCA pathogenic mutations. Negative controls did not show deleterious variants, confirming the suitability of the approach. In patients diagnosed with cancer we found 4 novel deleterious mutations (c.2805_2808delAGAT and c.3124_3133delAGCAATATTA in BRCA1; c.2639_2640delTG and c.5114_5117delTAAA in BRCA2. The prevalence of BRCA mutations in these patients was 10.2%. Moreover, we discovered 16 variants with unknown clinical significance (11 in exons and 5 in introns; 4 were predicted as possibly pathogenic by in silico analyses, and 3 have not been described previously. This study illustrates how massive pyrosequencing technology can be applied to screen for BRCA mutations in the whole exonic and splice regions in patients with suspected BRCA-related cancers. This is the first effort to analyse the mutational status of BRCA genes on a Mexican-mestizo population by means of pyrosequencing.

    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.

    Ruiz-Delgado, Guillermo J; Gómez Rangel, J David

    2004-01-01

    Monoclonal gammopathy of undetermined significance (MGUS) is defined as presence of serum monoclonal protein at a concentration of 3 g per deciliter or less, no monoclonal protein or only moderate amounts of monoclonal light chains in urine, absence of lytic bone lesions, anemia, hypercalemia, and renal insufficiency related with monoclonal protein, and with a proportion of plasma cells in bone marrow of 10% or less. In Caucasian population, MGUS affects about 3% of individuals > 70 years of age, whereas in Mexican mestizos this figure is substantially lower (0.7%); on the other hand, MGUS represents in Mexico only 2.4% of all monoclonal gammopathies. In a total of 9081 individuals studied prospectively at the Centro de Hematología y Medicina Interna de Puebla throughout a 20-year period, 11 patients with MGUS were identified. Median age was 70 years (range 43-83 years). Patients have been followed in periods ranging from 6 to 3270 days (median, 308 days). Two patients evolved into overt multiple myeloma at 308 and 1687 days after diagnosis of MGUS. Overall median survival (SV) of the group has not been reached, whereas 3270 days overall SV is 91%. After discussing underreporting, biasing, and other confounding factors, it would seem that MGUS, like other monoclonal gammopathies, is less frequent in Mexican mestizos than in Caucasians. Routine screening studies to identify the condition should result in increased numbers of patients.

    Full Text Available Abstract 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

    Although aryl hydrocarbon receptor-interacting protein (AIP) mutations are rare in sporadic acromegaly, their prevalence among young patients is nonnegligible. The objectives of this study were to evaluate the frequency of AIP mutations in a cohort of Mexican patients with acromegaly with disease onset before the age of 30 and to search for molecular abnormalities in the AIP gene in teeth obtained from the "Tampico Giant". Peripheral blood DNA from 71 patients with acromegaly (51 females) with disease onset T (p.Arg304Ter), well-known truncating mutation was identified; in one of these two cases and her identical twin sister, the mutation proved to be a de novo event, since neither of their parents were found to be carriers. In the remaining three patients, new mutations were identified: a frameshift mutation (c.976_977insC, p.Gly326AfsTer), an in-frame deletion (c.872_877del, p.Val291_Leu292del) and a nonsense mutation (c.868A > T, p.Lys290Ter), which are predicted to be pathogenic based on in silico analysis. Patients with AIP mutations tended to have an earlier onset of acromegaly and harboured larger and more invasive tumours. A previously described genetic variant of unknown significance (c.869C > T, p.Ala299Val) was identified in DNA from the Tampico Giant. The prevalence of AIP mutations in young Mexican patients with acromegaly is similar to that of European cohorts. Our results support the need for genetic evaluation of patients with early onset acromegaly.

    Full Text Available Lung cancer is the leading cause of cancer mortality in Mexico and worldwide. In the past decade, there has been an increase in the number of lung cancer cases in young people, which suggests an important role for genetic background in the etiology of this disease. In this study, we genetically characterized 16 polymorphisms in 12 low penetrance genes (AhR, CYP1A1, CYP2E1, EPHX1, GSTM1, GSTT1, GSTPI, XRCC1, ERCC2, MGMT, CCND1 and TP53 in 382 healthy Mexican Mestizos as the first step in elucidating the genetic structure of this population and identifying high risk individuals. All of the genotypes analyzed were in Hardy-Weinberg equilibrium, but different degrees of linkage were observed for polymorphisms in the CYP1A1 and EPHX1 genes. The genetic variability of this population was distributed in six clusters that were defined based on their genetic characteristics. The use of a polygenic model to assess the additive effect of low penetrance risk alleles identified combinations of risk genotypes that could be useful in predicting a predisposition to lung cancer. Estimation of the level of genetic susceptibility showed that the individual calculated risk value (iCRV ranged from 1 to 16, with a higher iCRV indicating a greater genetic susceptibility to lung cancer.

    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.

    Study goals were to examine the conditions under which congruent and incongruent patterns of parents' division of household labor and gender role attitudes emerged, and the implications of these patterns for youth gender development. Questionnaire and phone diary data were collected from mothers, fathers, and youths from 236 Mexican American families in the southwestern US. Preliminary cluster analysis identified three patterns: Traditional divisions of labor and traditional attitudes, egalitarian divisions of labor and egalitarian attitudes, and an incongruent pattern, with a traditional division of labor but egalitarian attitudes. MANOVAs, and follow-up, mixed- and between-group ANOVAs, revealed that these groups of families differed in parents' time constraints, socioeconomic resources, and cultural orientations. Mothers in the congruent egalitarian group worked more hours and earned higher incomes as compared to mothers in the congruent traditional and incongruent groups, and the emergence of the incongruent group was grounded in within-family, inter-parental differences in work hours and incomes. Parents' patterns of gendered practices and beliefs were linked to their youths' housework participation, time with mothers versus fathers, and gender role attitudes. Youths in the congruent traditional group had more traditional gender role attitudes than those in the congruent egalitarian and incongruent groups, and gender atypical housework participation and time with parents were only observed in the congruent egalitarian group. Findings demonstrate the utility of a within-family design to understand complex gendered phenomena, and highlight the multidimensional nature of gender and the importance of contextualizing the study of ethnic minorities.

    Prior to 2005, 51% of children in Mexico diagnosed with cancer received no standardized optimal multidisciplinary medical care. A government-subsidized national cancer treatment program was therefore created for these patients and a National Cooperative Childhood Cancer Treatment Group was consequently formed for these patients. Pediatric patients with a proven diagnosis of leukemia, lymphoma or solid tumor and who were registered in the Popular Medical Insurance (PMI) program from January 2007 to December 2010, are described in this report. These patients had been enrolled and registered in one of the 49 nationwide certified medical institutions in Mexico. The national incidence and frequency data for childhood cancers were analyzed for the whole program. At the end of a 4-year study, the analysis revealed that 8,936 children from across Mexico had been diagnosed with cancer. The incidence rate for the PMI patients was 150.3/million/year (2010) for children of 0-18 years. The highest age incidence rate was 51.9 between 0 and 4 years and boys were the predominant group for all types of cancer. The leukemia incidence was 75.3/million/year (2010), and an average frequency of 50.75% throughout the 4 years. The overall mortality rate was measured at 5.4/100,000/year (2010). This study demonstrates a high frequency and incidence of childhood cancer and a beneficial impact of the PMI program over the quality of life in these children.

    Background Breast cancer is one of the most common cancers diagnosed during pregnancy. Pregnancy-associated breast cancer (PABC) is defined as breast cancer diagnosed during pregnancy or within 12 months of delivery. Nowadays PABC can be safely diagnosed, staged, and treated during pregnancy with good outcomes for both the mother and the fetus. Recent studies suggest that prognosis of women diagnosed during postpartum seems to be worse. In order to gain a better understanding of the PABC, we reviewed our centre’s experience. Patients and methods We assessed the clinicopathological parameters, evolution, and outcome of patients treated in the Fundación Instituto Valenciano de Oncología of Valencia, Spain, from October 1990 to October 2013, and compared the results of patients diagnosed during pregnancy (group ‘A’) and patients diagnosed within one year of delivery (group ‘B’). Of 12,000 cases of breast cancer registered in our database, 35 cases of PABC were identified. We included 11 patients in group ‘A’ and 24 in group ‘B’. Results In our group the median age was 35 years (range 29–42), of which ten (28%) patients had family history (first grade) of breast cancer, four patients were BRCA 1 mutation carriers. Axillary node compromise was found in 19 patients (53.5%), 24 patients were stage II or III at diagnosis (68.5%), 22 (62.8%) were ER positive, and nine (25.7%) were HER-2 positive. In group A (n = 11), five patients diagnosed before 18th week decided that a therapeutic abortion be performed before treatment, two patients were treated during pregnancy, one with chemotherapy without treatment associated complications during delivery. Four women diagnosed after 28th week decided to delay the treatment until delivery. After a follow up of 172 months, the relapse free survival (RFS) was 69% at five years and 45% at ten years. Overall survival (OS) at five years was 90.8% and 74.2% at ten years for all patients. For group ‘A’ OS was higher

    Our aim in this paper is to describe the results of treatment of acute lymphoblastic leukaemia (ALL) in Mexican children treated from 2006 to 2010 under the protocol from the Dana-Farber Cancer Institute (DFCI) 00-01. The children were younger than 16 years of age and had a diagnosis of ALL de novo. The patients were classified as standard risk if they were 1–9.9 years old and had a leucocyte count 100 × 109/L. The poor outcomes were associated with toxic death during induction, complete remission, and relapse. These factors remain the main obstacles to the success of this treatment in our population.

    Latinas are more likely to exhibit late stage breast cancers at the time of diagnosis and have lower survival rates compared to white women. A contributing factor may be that Latinas have lower rates of mammography screening. This study was guided by the Behavioral Model of Health Services Use to examine factors associated with mammography screening utilization among middle-aged Latinas. An academic–community health center partnership collected data from community-based sample of 208 Latinas 40 years and older in the San Diego County who completed measures assessing psychosocial factors, health care access, and recent mammography screening. Results showed that 84.6 % had ever had a mammogram and 76.2 % of women had received a mammogram in the past 2 years. Characteristics associated with mammography screening adherence included a lower acculturation (OR 3.663) a recent physician visit in the past year (OR 6.304), and a greater confidence in filling out medical forms (OR 1.743), adjusting for covariates. Results demonstrate that an annual physical examination was the strongest predictor of recent breast cancer screening. Findings suggest that in this community, improving access to care among English-speaking Latinas and addressing health literacy issues are essential for promoting breast cancer screening utilization.

    The prevalence and genotype distribution of human papillomavirus (HPV) provides the basis for designing HPV prevention programs. The prevalence rates of type-specific HPV and coinfections in samples of Mexican women were investigated in 822 women aged 18-87 years. HPV detection was performed using a Linear Array™ genotyping test. HPV infection was found in 12.4% of controls, 46.3% of those with cervical intraepithelial neoplasia 1, and 100% of those with cervical intraepithelial neoplasia 3 or cervical cancer. HPV 16 was the most prevalent type in all diagnosis groups. The HPV types most frequently found in cervical cancers were 16, 18, 45, 52, 58, and 39; HPV types 16, 62, 51, 84, 18, 53, and CP6108 were the most prevalent in control women. Considering HPV-positive samples only, coinfections occurred most often in controls (63%) and were less frequent in those with cervical cancer (26%). The most frequent viral types in coinfections with HPV 16 in control women were HPV 62, 51, and 84; in women with cervical cancers, HPV 18, 39, and 70 were most common. In conclusion, in addition to HPV types 16 and 18, types 45, 39, 58, 52, and 71 were found in cervical cancers in Mexican women (78%); among them, only 65% were attributable to HPV types 16 and 18. Therefore, it is necessary to consider these viral types in the design of new vaccines, and to determine whether certain HPV types coinfecting with HPV 16 in precursor lesions determine tumor progression or regression.

    Here we give an overview of the Mexican experience of a national program, begun in 1997, of gradual implementation of computational tools in the lower secondary-school classrooms (children 12-15 years-old) for mathematics and science. This project illustrates, through the benefit of long-term hindsight, the successes and difficulties of large-scale massive implementation of technologies in schools. The key factors for success and for transforming school practices seem to be: adequate planning, gradual implementation, continuous training and support, and enough time (years) for assimilation and integration.

    This phenomenological study was designed to explore the lived experience of having cancer, as perceived by people who have been diagnosed and treated for cancer. The aim of the study was to add to the knowledge and understanding of this complex human phenomenon. Data were collected through in-depth interviews with nine people who were in the remission or recovery phase of cancer. The interviews were tape-recorded and transcribed verbatim for each participant. Through intersubjective interactions and thematic analysis, the essential description of the lived experience of having cancer was constructed. The overriding theme of the lived experience of having cancer is "experiencing existential changes." Five basic subthemes were identified in the participants accounts, all of which are part of the existential changes involved in the lived experience of having cancer. These are: uncertainty, vulnerability, isolation, discomfort, and redefinition. The study can increase the understanding of what it is like to have cancer.

    The development of a Lateral Total Body Irradiation protocol to be implemented at a High Specialty Medical Unit in Mexico as preparatory regimen for bone marrow transplant and treatment of several lymphomas is presented. This protocol was developed following AAPM specifications and has been validated for application at a cancer care center in United States. This protocol fundamentally focuses on patient care, avoiding instability and discomfort that may be encountered by other treatment regimes. In vivo dose verification with TLD-100 chips for each anatomical region of interest was utilized. TLD-100 chips were calibrated using a 6 MV photon beam for 10-120 cGy. Experimental results show TLD measurements with an error less than 1%. Standard deviations for calculated and measured doses for seven patients have been obtained. Data gathered for different levels of compensation indicate that a 3% measured tolerance level is acceptable. TLD point-dose measurements have been used to verify the dose beyond partial transmission lung blocks. Dose measurements beyond the lung block showed variation about 50% respects to prescribe dose. Midplane doses to the other anatomical sites were less than 2.5% respect of the prescribed dose.

    Full Text Available Abstract Background Sensation seeking tendencies tend to manifest during adolescence and are associated with both health-compromising behaviors and health-enhancing behaviors. The purpose of this study is to evaluate the relationship between sensation seeking and physical activity, a health-enhancing behavior, and between sensation seeking and experimenting with cigarettes, a health compromising-behavior, among a cohort of Mexican origin adolescents residing in the United States with different levels of acculturation. Methods In 2009, 1,154 Mexican origin youth (50.5% girls, mean age 14.3 years (SD = 1.04 provided data on smoking behavior, physical activity, linguistic acculturation, and sensation seeking. We conducted Pearson’s χ2 tests to examine the associations between categorical demographic characteristics (i.e. gender, age, country of birth and parental educational attainment and both cigarette experimentation and physical activity and Student’s t-tests to examine mean differences on the continuous variables (i.e. sensation seeking subscale by the behaviors. We examined mean differences in the demographic characteristics, acculturation, and both behaviors for each of the sensation seeking subscales using analysis of variance (ANOVA. To examine relationships between the sensation seeking subscales, gender, and both behaviors, at different levels of acculturation we completed unconditional logistic regression analyses stratified by level of acculturation. Results Overall, 23.3% had experimented with cigarettes and 29.0% reported being physically active for at least 60 minutes/day on at least 5 days/week. Experimenting with cigarettes and being physically active were more prevalent among boys than girls. Among girls, higher levels of sensation seeking tendencies were associated with higher levels of acculturation and experimentation with cigarettes, but not with physical activity. Among boys, higher levels of sensation seeking

    Full Text Available Abstract 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

    Gastric (GC) and breast (BrC) cancer are two of the most common and deadly tumours. Different lines of evidence suggest a possible causative role of viral infections for both GC and BrC. Wide genome sequencing (WGS) technologies allow searching for viral agents in tissues of patients with cancer. These technologies have already contributed to establish virus-cancer associations as well as to discovery new tumour viruses. The objective of this study was to document possible associations of viral infection with GC and BrC in Mexican patients. In order to gain idea about cost effective conditions of experimental sequencing, we first carried out an in silico simulation of WGS. The next-generation-platform IlluminaGallx was then used to sequence GC and BrC tumour samples. While we did not find viral sequences in tissues from BrC patients, multiple reads matching Epstein-Barr virus (EBV) sequences were found in GC tissues. An end-point polymerase chain reaction confirmed an enrichment of EBV sequences in one of the GC samples sequenced, validating the next-generation sequencing-bioinformatics pipeline. PMID:26910355

    Along a 17-year period 7,373 patients were prospectively studied in a private practice Health facility; of these 11 were patients with Waldenström's macroglobulinemia; calculations from these data and previous publications show that this lymphoid malignancy represents in Mexico 0.18% of all hematologic malignancies, a figure 11 times lower than that described from caucasians. The median age was 65 years (range 31 to 84); there were 6 males and 5 females. Ten individuals were mexican mestizos, whereas one had a caucasian phenotype. The clinical features of the patients afflicted by the disease in Mexico were similar to those reported from caucasian populations. The median survival (SV) of the group of patients was 40 months, whereas the 42-month survival was 49%; the prognosis of the disease was relatively good despite the fact that complete remissions were unfrequent as a result of the treatment.

    Full Text Available Squamous cervical carcinoma (SCC is the most common cancer found in Mexican women. Human papillomavirus (HPV infection is a prerequisite for this disease. In Mexico little is known about the prevalence of HPV-types and knowledge of the circulating genotypes by region is limited. The aim of this study was to determine the prevalence and genotypes of HPV in biopsies from women with intraepithelial lesions and SCC. A total of 211 cervical biopsies were studied. Histopathological analysis was done and HPV DNA was detected by PCR using MY09/MY11 (MY-PCR and GP5+/GP6+ (GP+PCR primers. Viral type was determined by RFLP’s or sequencing. Tissues were classified as low-grade squamous intraepithelial lesion (LSIL in 123 cases, high-grade squamous intraepithelial lesion (HSL in 40 and SCC in 48. Prevalence of HPV was 55.3% in LSIL, 65% in HSIL and 91.7% in SCC by MY-PCR. These percentages increased to 83, 77.5 and 100%, respectively, when HPV-negative samples were analyzed by GP+PCR. In 138 of 211 samples (65.4%, HPV was detected by MY-PCR and 43 (20.4% were positive by GP+PCR. In 166 (91.7% of 181 infections high risk HPV-types were found. Twelve genotypes were detected (16, 18, 31, 33, 45, 52, 58, 59, 61, 66, 70, 81. Prevalence of HPV 16 in LSIL, HSIL and SCC, were 70.6, 54.8 and 70.8%, respectively and it was the most common type in all cases (67.9%. A significantly higher number of positive samples were detected with MY-PCR and GP+PCR. The high prevalence of HPV infection with high-risk types, especially HPV16, among Mexican women with SIL and SCC, has important implications in the treatment and prophylaxis.

    2014-09-01

    Cancer is a critical disease with a high mortality rate in the US. Although useful information exists on the Internet, many people experience difficulty finding information about cancer prevention because they have limited eHealth literacy. This study aimed to identify relationships between the level of eHealth literacy and cancer information seeking experience or prior experience with cancer screening tests. A total of 108 adults participated in this study through questionnaires. Data covering demographics, eHealth literacy, cancer information seeking experience, educational needs for cancer information searching, and previous cancer screening tests were obtained. Study findings show that the level of eHealth literacy influences cancer information seeking. Individuals with low eHealth literacy are likely to be less confident about finding cancer information. In addition, people who have a low level of eHealth literacy need more education about seeking information than do those with a higher level of eHealth literacy. However, there is no significant relationship between eHealth literacy and cancer screening tests. More people today are using the Internet for access to information to maintain good health. It is therefore critical to educate those with low eHealth literacy so they can better self-manage their health.

    A total of 1165 patients with stomach cancer were entered into a prospective, observational national study. They represented 54 per cent of all stomach cancer patients reported to the Cancer Registry in Norway during the study period, and data are analysed for three hospital levels (local, county and university hospitals). The median age was 71 years (range 18-96 years). The median pretreatment delay was 113 days, and 46 per cent of patients had a performance status (Karnofsky index) of less than or equal to 80. The diagnosis was confirmed by pre-operative histology in 88 per cent of cases. In all, 88 per cent of patients underwent surgery, the resectability rate was 67 per cent and 50 per cent had a potential curative operation. Total gastrectomy was most commonly performed. Lymph node dissection was performed in 14 per cent of those undergoing a curative resection. The postoperative complication rate was 27 per cent but varied with the type of operation, being highest in proximal resection (55 per cent) and lowest after distal resection (19 per cent). A total of 7 per cent of the patients died postoperatively. Most patients had advanced disease at the time of treatment and only 6 per cent had stage I tumours. There were significant differences in patient and treatment characteristics between the three hospital levels. In conclusion, patient selection bias which will influence results does occur. A fairly aggressive attitude towards local disease was found, but the low proportion of patients undergoing lymph node dissection not only leads to questions regarding the efficacy of this treatment policy, but also casts doubt on the validity of staging of stomach cancer. Morbidity and mortality rates are still high. The consequences of the differences revealed between hospital groups are difficult to interpret.

    2013-06-01

    Colorectal cancer (CRC) has formed a canonical example of tumourigenesis ever since its use in Fearon and Vogelstein\\'s linear model of genetic mutation, and continues to generate a huge amount of research interest. Over time, the field has witnessed a transition from solely experimental work to the inclusion of mathematical and computational modelling. The fusion of these disciplines has the potential to provide valuable insights into oncologic processes, but also presents the challenge of uniting many diverse perspectives. Furthermore, the cancer cell phenotype defined by the \\'Hallmarks of Cancer\\' has been extended in recent times and provides an excellent basis for future research. The authors present a timely summary of the literature relating to CRC, addressing the traditional experimental findings, summarising the key mathematical and computational approaches, and emphasising the role of the Hallmarks in current and future developments. The authors conclude with a discussion of interdisciplinary work, outlining areas of experimental interest which would benefit from the insight that theoretical modelling can provide. © The institution of engineering and technology 2013.

    2012-04-01

    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.

    Summary Background Breast cancer is a public health problem and it is the most common gynecologic neoplasia worldwide. The risk factors for its development are of both hereditary and environmental origin. Certain foods have been clearly associated with modifying the breast cancer risk. The aim of the present analysis was to evaluate the effects of cow's milk and meat consumption on the development of breast cancer in a population from Western Mexico (Colima). Material and Methods We studied 97 patients presenting with a histopathologic diagnosis of breast cancer and 104 control individuals who did not present with the disease (Breast Imaging Report and Data System (BI-RADS) 1-2). 80% of the population belonged to a low socioeconomic stratum. The main clinical characteristics were analyzed along with the lifetime consumption of meat and milk. Results High milk consumption increased the breast cancer risk by 7.2 times (p = 0.008) whereas the consumption of meat was not significantly associated with the disease. Conclusions High consumption of cow's milk was a risk factor for the development of breast cancer. Further studies are needed to evaluate the effects of dietary patterns on the development of breast cancer in diverse populations with ethnic, cultural, and economic differences. PMID:26989358

    Health-related quality of life (HRQL) is a fundamental outcome in surgical oncology and culturally valid tools are essential for this purpose. Our aim was to validate the Mexican-Spanish versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire QLQ-C30 and the QLQ-STO22 disease-specific questionnaire module in Mexican patients with gastric cancer (GC). The translation procedure followed EORTC guidelines. Both instruments were completed by patients with GC and analyses were performed within three clinically distinct groups: (1) patients undergoing palliative treatment, (2) patients undergoing treatment with curative intent, and (3) GC survivors. Tests for reliability and validity were performed. One hundred and fifty patients (mean age 54.2 years) completed both questionnaires. Sixty-seven, 55, and 28 patients were allocated to groups 1, 2, and 3, respectively. Compliance rates were high, and questionnaires were well-accepted. Survivors of treatment for GC reported better functional HRQL scores and lower symptom scores than patients in group 2 who were currently undergoing treatment. Patients selected for potentially curative treatment had better HRQL than group 1 (palliative treatments). Scales in the QLQ-C30 and QLQ-STO22 distinguished between other clinically distinct groups of patients. Cronbach's alpha coefficients of 14 scales of both questionnaires were >0.7. Multitrait scaling analysis demonstrated good convergent and discriminant validity. Test-retest scores were consistent. We conclude that the Mexican-Spanish versions of EORTC QLQ-C30 and QLQ-C22 questionnaires are reliable and valid for HRQL measurement in patients with GC and are therefore recommended for use in clinical trials of Mexican community.

The results empirically support the emerging body of research regarding young adults with cancer. They stress the need for more specific research, clinically and politically appropriate services to this group of cancer patients. Thanks to technology, young people living with cancer, now have an opportunity to actively participate in providing information regarding their subjective experiences. This will challenge the traditional hierarchy of knowledge, where healthcare professionals and researchers reign over the power of knowledge and decisions.

    Lacking in the literature are data addressing the extent to which changes in reproductive and lifestyle factors predispose women in developing nations to higher breast cancer rates, and the degree to which these are due to globalization influences. This article describes the development and psychometric assessment of an instrument intended to measure global, predominantly U.S., influences on breast cancer risk profile among women residing in Mexico. Using investigator consensus and a focus group methodology, the Measure of Globalization Influence on Health Risk (MGIHR) was developed and completed by 341 women. Psychometric analysis support the use of an 11-item Consumerism and Modernity scale and 7-item Reproductive Control and Gender Role scale. The MGIHR is a valid and reliable instrument for understanding changing lifestyle and reproductive factors for breast cancer risk and may provide a more complete understanding of breast cancer development and needed interventions.

    Full Text Available Gastrointestinal (GI cancers are a significant source of morbidity and mortality in Iran, with stomach adenocarcinoma as the most common cancer in men and the second common cancer in women. Also, some parts of Northern Iran have one of the highest incidences of esophageal cancer in the world. Multi-disciplinary organ-based joint clinics and tumor boards are a well-recognized necessity for modern treatment of cancer and are routinely utilized in developed countries, especially in major academic centres. But this concept is relatively new in developing countries, where cancer treatment centres are burdened by huge loads of patients and have to cope with a suboptimum availability of resources and facilities. Cancer Institute of Tehran University of Medical Sciences is the oldest and the only comprehensive cancer treatment centre in Iran, with a long tradition of a general tumor board for all cancers. But with the requirements of modern oncology, there has been a very welcome attention to sub-specialized organ-based tumor boards and joint clinics here in the past few years. Considering this, we started a multi-disciplinary tumor board for GI cancers in our institute in early 2010 as the first such endeavor here. We hereby review this 2-year evolving experience. The process of establishment of a GI tumor board, participations from different oncology disciplines and related specialties, the cancers presented and discussed in the 2 years of this tumor board, the general intents of treatment for the decisions made and the development of interest in this tumor board among the Tehran oncology community will be reviewed. The GI tumor board of Tehran Cancer Institute started its work in January 2010, with routine weekly sessions. A core group of 2 physicians from each surgical, radiation and medical oncology departments plus one gastroenterologist, GI pathologist and radiologist was formed, but participation from all interested physicians was encouraged.

    Full Text Available Introduction: The populations who survive from breast cancer are growing; nevertheless, they mostly encounter with many cancer related problems in their life, especially after early diagnosis and have to deal with these problems. Except for the disease entity, several socio-cultural factors may affect confronting this challenge among patients and the way they deal with. Present study was carried out to prepare clear understanding of Iranian women's lived experiences confronting breast cancer diagnosis and coping ways they applied to deal with it. Methods: This study was carried out by using qualitative phenomenological design. Data gathering was done through purposive sampling using semi-structured, in-depth interviews with 18 women who survived from breast cancer. The transcribed interviews were analyzed using Van Manen’s thematic analysis approach. Results: Two main themes were emerged from the interviews including "emotional turbulence" and "threat control". The first, comprised three sub themes including uncertainty, perceived worries, and living with fears. The second included risk control, recurrence control, immediate seeking help, seeking support and resource to spirituality. Conclusion: Emotional response was the immediate reflection to cancer diagnosis. However, during post-treatment period a variety of emotions were not uncommon findings, patients' perceptions have been changing along the time and problem-focused coping strategies have replaced. Although women may experience a degree of improvement and adjustment with illness, the emotional problems are not necessarily resolved, they may continue and gradually engender positive outcomes.

    2011-01-01

    This essay presents an overview of artists and writers who read Freud's work in Mexico between 1920 and 1968. The focus is on cultural readings of Freud: non-clinical interpretations of psychoanalysis that applied Freud's theory to literary, artistic, philosophical, or religious questions. The essay focuses on Salvador Novo, one of the poets associated with the Contemporáneos group, and his reading of the "Three Essays in the Theory of Sexuality;" Raúl Carrancá y Trujillo, a judge and criminologist who used psychoanalysis in his work, including the trial of Trotky's assassin; Octavio Paz, a poet and intellectual who wrote an essay on Mexican history, "The Labyrinth of Solitude," as a response to "Moses and Monotheism;" and Gregorio Lemercier, a Benedictine monk who placed his monastery in group analysis. These unorthodox readings of Freud opened the door for some of the most daring intellectual experiments in the 20th century.

    Introduction Prevention programs have not achieved the expected results in preventing mortality from breast and cervical cancer in Mexico. Therefore, we propose a complementary strategy. Methodology An educational strategy for high school students in Mexico (2011–2013) was designed (longitudinal design, two measurements and a single intervention). The postintervention assessment included: 1) knowledge acquired by students about cancer prevention and 2) The performance of the student as a health promoter in their household. The strategy was based on analysis of cases and developed in three sessions. An assessment tool was designed and validated (Test–Retest). The levels of knowledge according to the qualifications expected by chance were determined. Wilcoxon test compared results before and after intervention. Results An assessment instrument with 0.80 reliability was obtained. 831 high school students were analyzed. Wilcoxon rank-sum test showed a significant learning after the intervention (Z = − 2.64, p = 0.008) with improvement of levels of knowledge in a 154.5%. 49% of students had a good performance as health promoters. Conclusions The learning in preventive measures is important to sensitize individuals to prevention campaigns against cancer. This strategy proved to improve the level of knowledge of students in an easy and affordable way. PMID:26844079

    Health staff-patient communication is increasingly considered an important issue in cancer research. However, questionnaires addressing satisfaction with communication limit the issues patients can raise, do not address the context of communication and often show a strong positive skew in responses....... Thus, qualitative studies of communication are also needed. Fifteen breast cancer patients were interviewed 3 months after finishing adjuvant treatment. They were asked to tell a 10 minute narrative and recall five experiences from treatment. Themes were extracted using categories derived from previous...... research while at the same time being sensitive to new elaborations and categories. The participants reported both positive and negative communication-related experiences from a wide range of treatment situations. Two major themes emerged: Information giving as professional care-giving and meeting...

    Breast cancer ranks first in incidence and mortality in working age women. Cancer initiation and progression relies on accumulation of genetic and epigenetic aberrations that alter cellular processes, among them, epithelial to mesenchymal transition (EMT) denotes particularly aggressive neoplasias given its capacity to invade and metastasize. Several microRNAs (miRNA) have been found able to regulate gene expression at the core of EMT. In this study, the Affymetrix CytoScan HD array was used to analyze three different primary tumor cell isolates from Mexican breast cancer patients. We found an amplification in band 22q11.2 shared by the three samples, in the region that encodes miRNA-650. Overexpression of this miRNA has been associated with downregulation of tumor suppressors ING4 and NDRG2, which have been implicated in cancer progression. Using the Pathway Linker platform the ING4 and NDRG2 interaction networks showed a significant association with signaling pathways commonly deregulated in cancer. Also, several studies support their participation in the EMT. Supporting the latter, we found that the three primary isolates were E-cadherin negative, vimentin positive, presented a cancer stem cell-like phenotype CD44+CD24−/low and were invasive in Transwell invasion assays. This evidence suggests that the gain of region 22q11.2 contributes to trigger EMT. This is the first evidence linking miR-650 and breast cancer. PMID:28101578

    In this article we draw on Bury's theory of biographical disruption to discuss the meanings of, and emotional experiences related to, being diagnosed with breast cancer among southern Thai women. Qualitative methods, including in-depth interviewing and drawing methods, were used to collect data from 20 women with breast cancer. The women perceived breast cancer to be a rhok raai; an evil or dread disease. They believed that breast cancer would lead to death. The disruption in their biography occurred when they detected abnormalities indicating breast cancer. The women's narratives revealed their chaotic lives upon this diagnosis and the news precipitated in them shock, fear, anxiety and loss of hope. Although they experienced chaos and disruption, the women cultivated strategies that helped them cope with their experiences by accepting their fate and adhering to Buddhist beliefs and practices. Through their narratives of biographical disruption, the women in our study offer healthcare providers knowledge that could lead to an appreciation of their needs and concerns. This knowledge is crucial for health professionals who wish to provide emotional support to women who have been diagnosed with breast cancer in Thailand and elsewhere.

    Full Text Available BackgroundWell-differentiated thyroid cancer (WDTC is the most common form of thyroid malignancy. While it is typically associated with good prognosis, it may exhibit higher recurrence and mortality rates in selected groups, particularly Filipinos. This paper aims to describe the experience of a Philippine Hospital in managing patients with differentiated thyroid cancer.MethodsWe performed a retrospective cohort study of 723 patients with WDTC (649 papillary and 79 follicular, evaluating the clinicopathologic profiles, ultrasound features, management received, tumor recurrence, and eventual outcome over a mean follow-up period of 5 years.ResultsThe mean age at diagnosis was 44±13 years (range, 18 to 82, with a majority of cases occurring in the younger age group (<45 years. Most tumors were between 2 and 4 cm in size. The majority of papillary thyroid cancers (PTCs, 63.2% and follicular thyroid cancers (FTCs, 54.4% initially presented as stage 1, with a greater proportion of FTC cases (12.7% vs. 3.7% presenting with distant metastases. Nodal metastases at presentation were more frequent among patients with PTC (29.9% vs. 7.6%. A majority of cases were treated by complete thyroidectomy, followed by radioactive iodine therapy and thyroid stimulating hormone suppression, resulting in a disease-free state. Excluding patients with distant metastases at presentation, the recurrence rates for papillary and FTC were 30.1% and 18.8%, respectively.ConclusionOverall, PTC among Filipinos was associated with a more aggressive and recurrent behavior. FTC among Filipinos appeared to behave similarly with other racial groups.

    2013-06-01

    In this study, we explored women's experiences with their bodies following treatment for breast cancer. Eleven women who had been treated for the disease (M(time since treatment)=4.45 years) were interviewed. Data were collected and analyzed using interpretative phenomenological analysis (Smith et al., 2009). Four main themes emerged from the data: changing visibly and invisibly; experiencing intense thoughts and emotions; meaning of the body: a vehicle of health, well-being, and social expression; and managing and dealing with physical changes. Overall, the women experienced various physical changes that shaped, mostly in a negative way, their perceptions, thoughts, attitudes, feelings, and beliefs about their bodies. The women described attempts to make positive lifestyle behavior choices (e.g., diet, participate in physical activity), and used other strategies (e.g., wigs, make-up, clothes) to manage their appearances and restore positive body-related experiences. Based on these findings, it is important to be cognizant of women's body image concerns following breast cancer given the poignant and lasting effects they can have on their psychosocial and emotional well-being.

    cells and peptide pulsed DCs. The principle behind combining NK cells and CTLs is a dual advantage approach combining the innate immune system and adaptive immune system wherein the CTLs will kill the MHC expressing cancer cells while NK cells will kill the MHC non-expressing cancer cells also. [10] In case of NK cells and DCs, DCs will in turn activate the CTLs thereby giving rise to the dual advantage mentioned above. We have recently suggested that the AIET using expanded NK cells, particularly in combination with monoclonal antibody drugs, may be very useful tool for cancer immunotherapy. [14] Our experience: In our studies in NOG SCID mice, activated NK cells were shown to reduce the size of breast cancer cells (MDA-MB231 [15] and the volume of ascites also inhibiting lung metastasis of pleural effusion lymphoma (PEL cells. [16] In a primary lung adenocarcinoma patient where AIET was administered in combination with Hyperthermia, the CEA values decreased from 4.8 ng/ml to 1.6 ng/ml, the SLX decreased from 30 U/ml to 27 U/ml, the IAP reduced from 300 μg/ml to 221 μg/ml along with resolution of the lung lesions in four months. A 55 year old woman treated for invasive ductal carcinoma of breast presented with metastasis to the lungs. She was then treated with trastuzumab in combination with multiple injections of activated natural killer (NK cells (at two week intervals following which the tumor markers decreased. Progression free survival was 10 months.

    Purpose: Our practice policy has been to provide intraoperative radiotherapy (IORT) at resection to patients with head-and-neck malignancies considered to be at high risk of recurrence. The purpose of the present study was to review our experience with the use of IORT for primary or recurrent cancer of the parotid gland. Methods and Materials: Between 1982 and 2007, 96 patients were treated with gross total resection and IORT for primary or recurrent cancer of the parotid gland. The median age was 62.9 years (range, 14.3-88.1). Of the 96 patients, 33 had previously undergone external beam radiotherapy as a component of definitive therapy. Also, 34 patients had positive margins after surgery, and 40 had perineural invasion. IORT was administered as a single fraction of 15 or 20 Gy with 4-6-MeV electrons. The median follow-up period was 5.6 years. Results: Only 1 patient experienced local recurrence, 19 developed regional recurrence, and 12 distant recurrence. The recurrence-free survival rate at 1, 3, and 5 years was 82.0%, 68.5%, and 65.2%, respectively. The 1-, 3-, and 5-year overall survival rate after surgery and IORT was 88.4%, 66.1%, and 56.2%, respectively. No perioperative fatalities occurred. Complications developed in 26 patients and included vascular complications in 7, trismus in 6, fistulas in 4, radiation osteonecrosis in 4, flap necrosis in 2, wound dehiscence in 2, and neuropathy in 1. Of these 26 patients, 12 had recurrent disease, and 8 had undergone external beam radiotherapy before IORT. Conclusions: IORT results in effective local disease control at acceptable levels of toxicity and should be considered for patients with primary or recurrent cancer of the parotid gland.

  10. Grandparents' experiences of childhood cancer, part 1: doubled and silenced.

    2012-01-01

    In this study, the authors examined the experiences of grandparents who have had, or have, a grandchild with childhood cancer. Sixteen grandparents were interviewed using unstructured interviews, and the data were analyzed according to hermeneutic-phenomenological tradition, as guided by the philosophical hermeneutics of Hans-Georg Gadamer. Interpretive findings indicate that grandparents suffer and worry in many complex ways that include a doubled worry for their own children as well as their grandchildren. According to the grandparents in this study, this worry was, at times, silenced in efforts to protect the parents of the grandchild from the burden of concern for the grandparent. Other interpretations include the nature of having one's universe shaken, of having lives put on hold, and a sense of helplessness. The grandparents in this study offer advice to other grandparents as well as to the health care system regarding what kinds of things might have been more helpful to them as one level of the family system, who, like other subsystems of the family, are also profoundly affected by the event of childhood cancer.

    Illness is constituted by subjective experiences of symptoms and their psychosocial consequences. Illness perceptions concern people's lay beliefs about understandings and interpretation of a disease and expectations as to disease outcome. Our knowledge about illness perceptions and coping in relation to the cancer care context among persons with colorectal cancer (CRC) and their partners is incomplete. The aim of the present study was to explore illness perceptions in relation to contemporary cancer care settings among CRC survivors and partners. The present research focused on illness rather than disease, implying that personal experiences are central to the methodology. The grounded theory method used is that presented by Kathy Charmaz. The present results explore illness perceptions in the early recovery phase after being diagnosed and treated for cancer in a contemporary cancer care setting. The core category outlook on the cancer diagnosis when quickly informed, treated, and discharged illustrates the illness perceptions of survivors and partners as well as the environment in which they were found. The cancer care environment is presented in the conceptual category experiencing contemporary cancer care settings. Receiving treatment quickly and without waiting was a positive experience for both partners and survivors; however partners experienced the information as massive and as causing concern. The period after discharge was being marked by uncertainty and loneliness, and partners tended to experience non-continuity in care as more problematic than the survivor did. The results showed different illness perceptions and a mismatch between illness perceptions among survivors and partners, presented in the conceptual category outlook on the cancer diagnosis. One illness perception, here presented among partners, focused on seeing the cancer diagnosis as a permanent life-changing event. The other illness perception, here presented among survivors, concentrated on

    Gestational breast cancer (GBC) presents many challenges for women and the clinicians who care for them. The aim of this study was to explore the health care experiences of women diagnosed with GBC to inform and improve clinical care of women in this predicament. Semi-structured interviews were conducted with 17 women who had been diagnosed with GBC in the previous 5 years. The overarching themes for perceived quality of care were "communication" and "comprehensive care." "Communication" had two sub themes: "interdisciplinary communication" (the way health professionals from different disciplines communicated with each other about the management of the woman's care) and "patient communication" (how they communicated this to the woman). The "comprehensive care" theme incorporated three sub themes: "the spirit" (psychological care); "the mind" (information provision); and "the body" (management of treatment side effects). Women's own accounts of positive and negative experiences of GBC care provide unique and specific insights which improve understanding of their concerns and needs. The findings can inform advances in quality and efficacy of clinical care; offer guidance for obstetricians, oncologists and allied health professionals about the needs of women diagnosed with GBC and how care can be optimised; and inform the development of resources to assist women and their families.

    We report our multicentric experience with sentinel lymph node biopsy for breast cancer patients. Patients with breast cancer operated on from January 1999 to March 2005 in 6 different institutions in the Rome area were retrospectively reviewed. All patients gave written informed consent. 1440 consecutive patients were analysed, with a median age of 59 years (range: 33-81) and a median tumour diameter of 1.3 cm (range: 0.1-5). Patients underwent lymphatic mapping with Tc99 nanocolloid (N = 701; 49%), with Evans Blue (N = 70; 5%), or with a combined injection (N = 669, 46%). The majority of patients were mapped with an intradermal or subdermal injection (N = 1193; 84%), while an intraparenchymal or peritumoral injection was used in 41 (3%) and 206 patients (13%), respectively. Sentinel lymph nodes were identified in 1374/1440 cases (95.4%), and 2075 sentinel lymph nodes were analysed (average 1.5/patient). A total of 9305 additional non-sentinel lymph-nodes were removed (median 6/patient). Correlations between sentinel lymph nodes and final lymph node status were found in 1355/1374 cases (98.6%). There were 19 false-negative cases (5%). Lymph node metastases were diagnosed in 325 patients (24%). In this group, micrometastases (< 2 mm in diameter) were diagnosed in 103 cases (7.6%). Additionally, isolated tumour cells were reported in 61 patients (4,5%). In positive cases, additional metastases in non-sentinel lymph-nodes were identified in 117/325 cases after axillary dissection (36%). Axillary dissection was avoided in 745/1440 patients (52%). At a median follow-up of 36 months, only 1 axillary recurrence has been reported. Sentinel lymph node biopsy improves staging in women with breast cancer because it is accurate and reproducible, and allows detection of micrometastases and isolated tumour cells that would otherwise be missed. Our multicentric study confirms that this is the preferred axillary staging procedure in women with breast cancer.

    Full Text Available Cervical cancer remains the most common cancer among women. It is the second major cause of women’s deaths in Asia as well as in Indonesia. Cervical cancer treatment also raises issues of long-term physical, psychological, sexual, and social adaptation. The purpose of the study was to describe and to interpret the experiences of Indonesian women who have experienced sexual dysfunction after cervical cancer treatment. Thirteen Indonesian women who were participated in this study described their experiences on the first to two years after cervical cancer treatment. Data were collected through in-depth interviews. Four themes were identified (1 physical and psychological sexual complaints after cancer treatment; (2 negative effects of cancer treatment towards intimate relationship with their spouse; (3 efforts to overcome sexual problems; and (4 women’s needs for help to improve their sexual health. These study findings offer providing new insights into the experiences of Indonesian women with sexual health problems following cervical cancer treatment. This study can provide nurses and other health care providers with better understanding of the experiences, concern and needs of the cancer survivors.

    Sperm banking is an important procedure to preserve fertility before cancer therapy. The aim of this study was to comprehensively analyse cryopreservation activity retrospectively for 1080 patients referred to the sperm bank for sperm cryopreservation before cancer treatment. This study included 1007 patients diagnosed with testicular cancer (TC) (41.7%), lymphoma (26%), other haematological cancers (9.4%) or other types of cancer (22.8%); of these, 29 patients did not produce any semen sample and cryopreservation was impossible for 67 patients. Semen characteristics before treatment were within normal ranges, except moderate asthenospermia. Sperm concentration was significantly lower in TC than in non-TC. Straws from 57 patients (6.3%) were used in assisted reproductive technologies, which led to a 46.8% cumulative birth rate. Straws were destroyed for 170 patients (18.7%) and 140 patients performed semen analyses after cancer therapy. After an average delay of 22.5 months after the end of therapy, 43 patients (30.7%) exhibited azoospermia. This study of a large population of cancer patients revealed a high level of successful sperm storage. Utilization of cryopreserved spermatozoa led to good chances of fatherhood. Nevertheless, sperm banks should be aware of the low rates of straw use and straw destruction by cancer patients.

    This represents the first published account from the patient's perspective of the use of human milk as cancer therapy. Purposive sampling was used to select a sample of 10 participants. Five were patients and 5 were family proxies. Individual interviews were conducted using confirmatory interviewing technique to obtain individual perspectives on the motivation for cancer patients to take donated human milk. Human milk therapy improved the quality of life (QOL) measures in the physical, psychological, and spiritual domains for most patients interviewed. The patients continued their use of human milk despite cost, taste, and discouragement from the conventional medical community. The study results support the theory that QOL may be more important to cancer patients than cancer outcomes and may improve patient medical care overall. These interviews offer information to cancer patients, their practitioners, and donor milk banks on outcomes and symptom relief from this therapy.

    Adrenocortical carcinoma (ACC) is a malignant endocrine tumour. The rarity of the disease has stymied therapeutic development. Age distribution shows two peaks: the first and fifth decades of life, with children and women more frequently affected. Although 60-70% of ACCs are biochemically found to overproduce hormones, it is not clinically apparent in many cases. If present, endocrine symptoms include signs of hypercortisolaemia, virilisation or gynaecomastia. ACC carries a poor prognosis, and a cure can be achieved only by complete surgical resection. Mitotane is used both as an adjuvant treatment and also in non-operative patients. The role of radio- and chemotherapy is still controversial. The post-operative disease free survival is low and oscillates around 30% due to high tumour recurrence rate. The diagnosis is based on tumour histological assessment with the use of the Weiss score, however urinary steroid profiling (if available) can serve to differentiate between ACC and other adrenal tumours. Conventional prognostic markers in ACC include stage and grade of disease, and, as currently reported, the presence of hypercortisolaemia. Molecular analysis has had a significant impact on the understanding of the pathogenetic mechanism of ACC development and the evaluation of prognostic and predictive markers, among which alterations of the IGF system, the Wnt pathway, p53 and molecules involved in cancer cell invasion properties and angiogenesis seem to be very promising. We here summarise our own experience related to the management of ACC and present a literature overview. We have not aimed to include a detailed summary of the molecular alterations biology described in ACC, as this has already been addressed in other papers.

    We report our initial experience and the technical feasibility of transperineal prostate cryoablation under MR guidance. Percutaneous MR-guided cryoablation was performed in 11 patients with prostatic adenocarcinoma contraindicated for surgery (mean age: 72 years, mean Gleason score: 6.45, mean prostate-specific antigen (PSA): 6.21 ng/ml, T1-2c/N0/M0, mean: prostate volume 36.44 ml). Free-hand probe positioning was performed under real-time MR imaging. Four to seven cryoprobes were inserted into the prostate, depending on gland volume. The ice ball was monitored using real-time and high-resolution BLADE multi-planar imaging. Patients were followed at 1, 3, 6, 9 and 12 months after the procedure with serum PSA level and post-ablation MRI. Prostate cryoablation was technically feasible in 10/11 patients. The ice ball was clearly and sharply visualised in all cases as a signal-void area. Mean ice-ball volume was 53.3 ml. Mean follow-up was 15 months (range: 1-25). Mean PSA nadir was 0.33 ng/ml (range: 0.02-0.94 ng/ml). Mean hospitalisation was 5 days (range: 3-13). Complications included a urethro-rectal fistula, urinary infection, transient dysuria and scrotal pain. MR-guided prostate cryoablation is feasible and promising, with excellent monitoring of the ice ball. Future perspectives could include the use of MR guidance for focal prostate cancer cryotherapy.

    Plasmodium of Physarum polycephalum is a single cell visible by unaided eye. During its foraging behavior the cell spans spatially distributed sources of nutrients with a protoplasmic network. Geometrical structure of the protoplasmic networks allows the plasmodium to optimize transport of nutrients between remote parts of its body. Assuming major Mexican cities are sources of nutrients how much structure of Physarum protoplasmic network correspond to structure of Mexican Federal highway network? To find an answer undertook a series of laboratory experiments with living Physarum polycephalum. We represent geographical locations of major cities by oat flakes, place a piece of plasmodium in Mexico city area, record the plasmodium's foraging behavior and extract topology of nutrient transport networks. Results of our experiments show that the protoplasmic network formed by Physarum is isomorphic, subject to limitations imposed, to a network of principle highways.

    Marine protected areas (MPAs) are attaining increasing importance in the management of marine ecosystems. They are effective for conservation in tropical and subtropical areas (mainly coral and rocky reefs), but it is debated whether they are useful in the management of migratory fish stocks in open temperate regions. World War II created a large marine area within which commercial fishing was prevented for 6 years. Here we analyse scientific trawl data for three important North Sea gadoids, collected between 1928 and 1958. Using statistical models to summarise the data, we demonstrate the potential of MPAs for expediting the recovery of over-exploited fisheries in open temperate regions. Our age-structured data and population models suggest that wild fish stocks will respond rapidly and positively to reductions in harvesting rates and that the numbers of older fish in a population will react before, and in much greater proportion, than their younger counterparts in a kind of Mexican wave. Our analyses demonstrate both the overall increase in survival due to the lack of harvesting in the War and the form of the age-dependent wave in numbers. We conclude that large closed areas can be very useful in the conservation of migratory species from temperate areas and that older fish benefit fastest and in greater proportion. Importantly, any rise in spawning stock biomass may also not immediately result in better recruitment, which can respond more slowly and hence take longer to contribute to higher future harvestable biomass levels.

    Endoscopic mucosal resection (EMR) has been established as one of the treatment options for early gastric cancer (EGC). However, there are many uncertain areas such as indications of EMR, best treatment methods, management of complications and follow-up methods after the procedure. Most studies on this topic have been carried out by researchers in Japan. In Korea,gastric cancer is the most common malignant disease,and the second leading cause of cancer death. In these days, EMR for EGC is widely performed in many centers in Korea. In this review, we will provide an overview of the techniques and outcomes of EMR in Korea.

    Latino immigrants are 50% more likely than all workers in the United States to experience a fatal injury at work. Occupational safety and health (OSH) organizations often find that the approaches and networks they successfully use to promote OSH among U.S.-born workers are ineffective at reaching Latino immigrants. This article describes the collaboration between the National Institute for Occupational Safety and Health (NIOSH) and the Mexican Ministry of Foreign Affairs (Secretaría de Relaciones Exteriores) to promote OSH among Mexican immigrant workers. The Ministry of Foreign Affairs operates 50 consulates throughout the U.S. that provide four million discrete service contacts with Mexican citizens annually. The focus of this ongoing collaboration is to develop the internal capacity of Mexican institutions to promote OSH among Mexican immigrants while simultaneously developing NIOSH's internal capacity to create effective and sustainable initiatives to better document and reduce occupational health disparities for Mexican immigrants in the U.S.

    Many young women with cancer have a high symptom burden and negative psychosocial consequences as a result of their disease. To offset some of these experiences, a growing number of young women with cancer are writing about their experience with complementary therapies through online illness blogs. The purpose of this qualitative study was to examine descriptions of complementary therapy use among young women (diagnosed between 20–39 years) who maintained an online cancer blog. Women’s narratives describe several themes of the experience of using complementary therapies including: awakening, new identities (that incorporate loss), the good stuff, and release. Online illness blogs allow researchers to understand the complete experience of the patient through personal accounts and substantially contributes to the body of knowledge surrounding cancer in young adulthood and complementary therapy use.

    Full Text Available Breast cancer is a leading cancer diagnosis among women worldwide, with more than 210,000 new cases and 40,000 deaths per year in the United States. Pain, anxiety, and depression can be significant factors during the course of breast cancer. Pain is a complex experience with sensory, affective, and cognitive dimensions. While depression and anxiety symptoms are relatively common among breast cancer patients, little is known about the relation between these psychiatric factors and distinct components of the pain experience. In the present study 60 females presenting to an NCI-designated Cancer Center with newly diagnosed breast cancer completed the Center for Epidemiological Studies 10-item Depression Scale, the State Instrument of the Spielberger State-Trait Anxiety Inventory, and the McGill Pain Questionnaire. Findings indicate that anxiety and depression are common among newly diagnosed breast cancer patients; furthermore, patients experience an appreciable amount of pain even before oncologic treatment starts. State anxiety serves as a predictor of the sensory dimension of the pain experience, whereas depression serves as a predictor of the affective dimension of the pain experience.

    The Virtual Solar Observatory (VSO) concept contains software tools for searching, manipulating, and analyzing data from archives of solar data at many different observatories around the world (Hill 2000). The VSO not only provides fast and reliable access to the existing solar data, but also represents a powerful and unique machinery to perform numerical simulations for the evolution of a variety of different phenomena associated with solar activity. Two Mexican Universities, Universidad Nacional Autónoma de México and the Universidad de Sonora, are working together to create the Mexican Virtual Solar Observatory (MVSO) that will be part of a wider National effort. In this work we present a general description of the MVSO project, as well as the advances obtained in the development of Graphical User Interfaces (GUI) to Remotely Perform Numerical Simulation of the Evolution of Coronal Mass Ejection in the Interplanetary Medium.

    During the XVIII century, two Spanish scientific expeditions arrived here led, respectively, by the naturalist Martín Sessé and by the Italian mariner Alessandro Malaspina di Mulazzo, dependent from the Spanish Government. The members collected a rich scientific material, which was carried to Madrid in 1820. At the end of XVIII century, the Franciscan friar Juan Navarro depicted and described several Mexican medicinal plants in the fifth volume of his "American Garden". In the last years of the Colonial period, fundamental works of Humboldt and Bonpland, on the geographic distribution of the American plants, were published. At the end of the XIX century, the first researches on the Mexican medicinal botany were performed at the laboratory of the "Instituto Médico Nacional" under the leadership of doctor Fernando Altamirano, starting pharmacological studies in our country. During the first half of the XX century, trials of cardiovascular pharmacology were performed in the small laboratories of the cardiological unit at the General Hospital of Mexico, due to doctor Ignacio Chávez, initiative. Mexican botanical-pharmacological tradition remains alive and vigorous in the modern scientific institutes of the country.

    Laryngeal cancer is about the twentieth most common cancer in the world and more than 150,000 new cases are diagnosed annually. The aim of the study was to evaluate the history, diagnostics, treatment outcomes, and prognosis in patients with laryngeal cancer in Northern Slovakia. We analyzed retrospectively 227 patients (207 males, 20 females) with laryngeal carcinoma treated in the period 2003-2014 at the Clinic of Otorhinolaryngology and Head and Neck Surgery of the Jessenius Faculty of Medicine and Martin University Hospital in Martin, Slovakia. The majority of patients were in the sixth (38.0 %) and seventh decade of life (30.8 %). Two hundred and seventeen patients (95.6 %) were smokers or ex-smokers. Sixty-six percent of patients were diagnosed with glottic or transglottic carcinoma, related probably to the anatomical structure of the larynx and exposure to inhalation pollutants. It is alarming that the majority of patients with malignant laryngeal disease were admitted to the hospital in advanced stages. In 151 (66.5 %) of patients, the extent of infiltration was T3 or T4, and 156 (68 %) patients were in disease stage III and IV. The incidence and mortality of laryngeal cancer suggest the need to intensify the prevention and to search for an early clinical stage of laryngeal cancer using a targeted screening.

    Disparities in cancer survivorship exist among specific populations of breast cancer survivors, specifically rural African American breast cancer survivors (AA-BCS). While effective survivorship interventions are available to address and improve quality of life, interventions must be culturally tailored for relevance to survivors. Here, we report the results of our formative research using focus groups and in-depth interview to better understand unique rural AA-BCS survivorship experiences and needs in the Alabama Black Belt. Surveys were used to gather sociodemographic and cancer treatment data. Fifteen rural AA-BCS shared their experiences and concerns about keeping their cancer a secret, lack of knowledge about survivorship, lingering symptoms, religion and spirituality, cancer surveillance, and general lack of survivorship education and support. Rural AA-BCS were unwilling to share their cancer diagnosis, preferring to keep it a secret to protect family and friends. Quality-of-life issues like lymphedema body image and sexuality were not well understood. They viewed spirituality and religion as essential in coping and accepting cancer. Participants also discussed the importance of and barriers to maintaining health through regular check-ups. They needed social support from family and friends and health care providers. Overall, rural AA-BCS expressed their need for knowledge about survivorship self-management by providing a vivid picture of the realities of cancer survival based on shared concerns for survivorship support and education within the context of culture.

    2004-01-01

    This paper is based on data collected from two different studies of parents (76 mothers and 14 fathers) whose children had been diagnosed with cancer. Although the goal of the first study, to describe parental experiences when their children have cancer, was different than the goal of the second study, to describe the home health care work done by parents whose children had cancer, the themes outlined here were reiterated from study to study. In both sets of data conflicts in the dynamics of power, authority and knowledge were pivotal to the dilemmas experienced by parents in their interactions with health care staff both during the time of diagnosis and later during the treatments when their children had cancer. The paper points to the significance of fundamental social processes such as power, authority and knowledge in understanding and ameliorating parental experiences when a child has cancer.

    Full Text Available Cognitive anthropology does not predict human behavior, but tries to access principles that rule behavior. Cross-cultural communication is a skill acquired through a learning process, and it can improve doctor-patient relationship and enhance the outcomes of care. The unfulfilled expectations of a patient may influence the patient self-esteem and his perceived role in the society. For some patients living with cancer, it was found as an unforeseen benefit of learning to be closer to God. Based on a narrative communication, we tried to underline cross-cultural differences in cancer patients from different countries with various backgrounds. We described the patient reactions, his way of interpreting the things that happened to him, and his actions regarding adaptive changes in behavior. The originality of the study resides in understanding cross-cultural patterns of cancer patients. The innovative element is the use of qualitative research and its application in health care.

    2013-12-01

    Full Text Available INTRODUCTION: There are unacceptable ethnic differences in cancer survival in Aotearoa/New Zealand. For people with cancer, quality of life and survival are shaped by access to care, but research on Maori access to, and through, cancer care is limited. Internationally, research has shown that primary care plays an important role in providing patient-centred, holistic care and information throughout the cancer care journey. Additionally, Maori health providers provide practical support and facilitate access to all levels of health care. Here we describe the cancer journeys of Maori patients and whanau and identify factors that may facilitate or inhibit access to and through cancer care services. METHODS: Twelve Maori patients affected by cancer and their whanau (family in the lower North Island took part in face-to-face semi-structured interviews exploring their experiences of cancer screening, diagnosis, treatment, survival and palliative care. FINDINGS: Three key areas were identified that impacted upon the cancer care journey: the experience of support; continuity of care; and the impact of financial and geographic determinants. CONCLUSION: Primary care plays a key role in support and continuity of care across the cancer journey. Alongside interpersonal rapport, a long-term relationship with a primary health provider facilitated a more positive experience of the cancer care journey, suggesting that patients with a 'medical home' are happier with their care and report less problems with coordination between services. Positive, longstanding relationships with general practitioners and Maori health providers assisted patients and whanau with the provision and understanding of information, alongside practical support.

    Full Text Available INTRODUCTION: In Mexico, breast cancer (BC is one of the main causes of cancer deaths in women, with increasing incidence and mortality in recent years. Therefore, the aim of the study is identify possible risk factors related to BC. METHODS: An epidemiological study of hospital cases of BC and controls with cervical uterine cancer (CUCA was carried out at eight third level concentration hospitals in Mexico City. The total of 353 incident cases of BC and 630 controls with CUCA were identified among women younger than 75 years who had been residents of the metropolitan area of Mexico City for at least one year. Diagnosis was confirmed histologically in both groups. Variables were analyzed according to biological and statistical plausibility criteria. Univariate, bivariate and multivariate analyses were carried out. Cases and controls were stratified according to the menopausal hormonal status (pre and post menopause. RESULTS: The factors associated with BC were: higher socioeconomic level (OR= 2.77; 95%CI = 1.77 - 4.35; early menarche (OR= 1.32; 95%CI= 0.88 - 2.00; old age at first pregnancy (>31 years: OR= 5.49; 95%CI= 2.16 - 13.98 and a family history of BC (OR= 4.76; 95% CI= 2.10 - 10.79. In contrast, an increase in the duration of the breastfeeding period was a protective factor (>25 months: OR= 0.38; 95%CI= 0.20 - 0.70. CONCLUSIONS: This study contributes to the identification of risk factors for BC described in the international literature, in the population of Mexican women. Breastfeeding appears to play an important role in protecting women from BC. Because of changes in women`s lifestyles, lactation is decreasing in Mexico, and young women tend not to breastfeed or to shorten the duration of lactation.OBJETIVO: O câncer de mama (CM é uma das principais causas de morte por câncer em mulheres, no México, com aumento da incidência e da mortalidade nos últimos anos.

    Objective: Implantable port thrombosis (IPT) in cancer patients is a relatively rare but severe complication. Several factors are reportedly associated with the occurrence of thrombosis. We aimed to describe the prevalence and the anatomoclinical features of IPT observed in cancer patients who were treated in a medical oncology department in Tunisia. Methods: A total of 600 cancer patients who had port implantation from January 2013 to December 2015 were retrospectively identified. Cases with symptomatic/incidental IPT (radiologically confirmed) were further identified. Epidemiological and anatomoclinical features were collected from patient records and the department database. Results: We observed that 33 of the 600 patients had IPT; thus, the prevalence was 5.5%. The median age was 57 years, and the gender ratio was 0.43. Overweight or obesity was observed in 73% of the patients. IPT occurred mainly in patients with breast (36.4%) and colorectal (33.3%) cancers, which were mostly nonmetastatic (79%). At least one identified classical thromboembolic risk factor was found in 13 patients (smoking in 9, tamoxifen in 2). IPT was symptomatic in 93% of the cases, occurring within an average time of 56 days. Implantable ports were removed because of infection in 2 cases and nonfunctionality in 3 cases. IPT treatment was based on low-molecular-weight heparins (94%) and antivitamin K (6%) for an average of 130 days. Four patients had post-therapy complications: one thrombosis recurrence and three infections. Conclusions: IPT cases in the 600 patients were observed to occur in obese nonmetastatic cancer patients within the first 3 months after IP implantation.

    The incidence of breast cancer and mortality from this disease remain high in countries with limited resources such as the Ukraine. Because of a lack of mammography equipment and formal screening programs, as well as educational and other factors, breast cancer is usually diagnosed in late stages in such countries. We report the experience of the PATH Breast Cancer Assistance Program in introducing a pilot breast cancer screening program in one territory of the Ukraine, the Chernihiv oblast. The program entailed educating the public, training health care providers in clinical breast examination (CBE) and mammography, opening a dedicated mammography facility, designating a center for breast cancer care, building diagnostic capacity, and fostering the formation of support groups. From 1998 to 2002, 18,000 women underwent screening with CBE and 8778 women underwent screening with mammography. When implementing the program we encountered various cultural, economic, and logistic difficulties, such as reservations about showing bare breasts in educational materials, the lack of an established system for collecting screening data, and barriers to follow-up in women with positive screening results. Screening mammography proved to be more effective in detecting small and nonpalpable lesions; 8.7% of cancers detected in the mammography group were in situ, compared with 0% in the CBE group. However, introduction of CBE as a screening modality required fewer financial resources compared with mammography and was recommended as a transitional method before the introduction of mammography screening programs in countries with limited resources. The introduction of screening was associated with favorable changes in indicators of breast cancer care, including an increase in the percentage of breast-preserving operations and new legislation to provide funding for breast cancer services. We conclude that this successful pilot program of breast cancer screening in a limited

    Objective: The objective of this study was to describe the experiences of Zambian nurses caring for women with advanced breast cancer. Methods: We used a qualitative descriptive design and purposive sampling. Seventeen in-depth interviews were conducted with registered nurses practicing in the Cancer Diseases Hospital and the University Teaching Hospital, Lusaka, Zambia, and analyzed using thematic analyses. Results: Two themes emerged from the data - caring for women with advanced breast cancer is challenging and the good outweighs the bad. The majority of the participants agreed that caring for women with advanced breast cancer and witnessing their suffering were challenging. Not having formal education and training in oncology nursing was disempowering, and one of the various frustrations participants experienced. The work environment, learning opportunities, positive patient outcomes, and the opportunity to establish good nurse–patient experiences were positive experiences. Conclusions: Although negative experiences seemed to be overwhelming, participants reported some meaningful experiences while caring for women with advanced breast cancer. The lack of formal oncology nursing education and training was a major factor contributing to their negative experiences and perceived as the key to rendering the quality of care patients deserved. Ways to fulfill the educational needs of nurses should be explored and instituted, and nurses should be remunerated according to their levels of practice. PMID:28217726

    Cancer rates for Canadian women between the ages of 22 and 44 are increasing. Improved survival times and more treatment choices, however create new challenges. Little research has been done to uncover the lived experience of long-term survival. This pilot study describes the meaning of living with cancer for three Canadian women who were diagnosed more than four years ago. The process of inquiry was Giorgi's descriptive phenomenological method for analysis-synthesis of a general structural description (the meaning of the experience). The findings have been interpreted creatively through poetry in an effort to enhance understanding of the experience of living with cancer Each section of the poem is discussed in relation to the literature to encourage nurses and other health professionals to consider the importance of understanding patients' lived experiences and the meanings they ascribe, in order to provide quality, holistic, and individualized care.

Discrete choice experiments are increasingly used to reveal preferences about new health services; however, selecting appropriate attributes that describe a new health service is imperative to ensure validity of the choice experiment.Objective: To identify important factors that are relevant to Malawian women’s preferences for breast cancer detection services and to select attributes and levels for a discrete choice experiment in a setting where both breast cancer early detection and choice experiments are rare.Methods: We reviewed the literature to establish an initial list of potential attributes and levels for a discrete choice experiment and conducted qualitative interviews with health workers and community women to explore relevant local factors affecting decisions to use cancer detection services. We tested the design through cognitive interviews and refined the levels, descriptions, and designs.Results: Themes that emerged from interviews provided critical information about breast cancer detection services, specifically, that breast cancer interventions should be integrated into other health services because asymptomatic screening may not be practical as an individual service. Based on participants’ responses, the final attributes of the choice experiment included travel time, health encounter, health worker type and sex, and breast cancer early detection strategy. Cognitive testing confirmed the acceptability of the final attributes

    Full Text Available Aim: Esophageal cancer remains a major and lethal health problem. In Nepal, not much has been explored about its management. The aim of this study was to conduct a retrospective review of esophageal cancer patients undergoing surgery or combined modality treatment at a cancer hospital in Nepal. Materials and Methods: Resectable cases were treated primarily with surgery. Locally advanced cases with doubtful or obviously unresectability underwent preoperative chemo/radiation or chemoradiation followed by surgery. Results: Among 900 patients, 103 were treated with curative intent. Mean age of patients was 54 years, and 100% of the patients presented with complaint of dysphagia. Surgery as a single modality of treatment was done in 57% of cases, and the remaining underwent combined modality treatment. Transthoracic and transhiatal approaches were used in 95% and 5% of cases, respectively. Nodal sampling, two-field (2-FD, and three-field lymphadenectomy (3-FD were done in 18%, 59%, and 20% of cases, respectively. A majority of patients had pathological stage III disease (46.6%. In-hospitality mortality was 5%, and anastomotic leakage rate was 14%. In 87% of patients, R0 resection was achieved. Overall, 4-year survival was 20%. A R0 resection, early-stage disease and 3-FD favored the survival advantage (P < 0.05. Conclusion: The mortality, complication, and survival results were in the acceptable range. R0 resection and radical nodal dissection should be standard practice.

    Full Text Available Aims and Objectives. To review the experience of a nurse-led colorectal cancer follow-up clinic in a tertiary referral colorectal cancer centre. Methodology. Data from the nurse-led colorectal cancer follow-up clinic in our unit was prospectively maintained in a colorectal cancer database. Data was analysed from January 1, 2006 until the December 31, 2011. Results. 1125 patients were diagnosed with colorectal cancer, and referred to our unit as a tertiary centre for specialised colorectal cancer. Nine hundred and four patients had surgical resection of their colorectal cancer. Four hundred and seven patients were referred to the nurse-led colorectal cancer clinic for surveillance. The mean age of the patient cohort was 67 years (range 32–88 and 56% of patients were male. One hundred and seventeen patients were discharged to their general practitioner having been disease free after 5 years of followup. Fifty-four patients were diagnosed with either local or distant recurrence. Conclusion. A nurse-led colorectal cancer follow-up clinic is running according to strict follow-up protocols. This type of clinic significantly reduces the number of routine follow-up patients that have to be seen by the colorectal surgical consultant.

    Full Text Available Background: Small cell bladder carcinoma is an uncommon tumor. In this retrospective study we report our experience dealing with this disease at the Leon-Berard Cancer Centre. Materials and Methods: We retrospectively analyzed various characteristics of small cell bladder carcinoma: patient demographics, histological diagnosis, disease stage, treatment effects and outcome, in 14 non-metastatic small cell bladder carcinoma patients treated at our institution between 1995 and 2006. Results: The mean age at diagnosis was 60 years (range, 45-77. All patients were male. Seventy-five per cent were smokers. All had locally advanced disease. Ten patients (71.4% were treated by cystoprostatectomy and bilateral pelvic lymph node resection, one by cystoprostatectomy alone. Two patients received neoadjuvant chemotherapy and four received adjuvant chemotherapy. One patient was treated by radiotherapy with concomitant cisplatin after transurethral resection of bladder tumor (TURBT. One patient refused surgery and was treated by chemotherapy alone. One patient was lost to follow-up after TURBT. After 49-month median follow-up, 12 patients had relapsed. Disease-free survival was 5.7 months. The most frequent sites of relapse were the retroperitoneal lymph node (seven patients and the liver (three patients. Nine patients died of metastasis. Median overall survival was 29.5 months. Survival probability at two years was 58%. Median overall survival was 34 months in the mixed small carcinoma group, as compared with 9.5 months in the pure small cell carcinoma group (P=0.01. Mean overall survival was 27.2 months for all patients and 38.6 months for patients treated with cystectomy and adjuvant chemotherapy. Conclusion: To date, the optimal treatment for locally advanced small cell bladder carcinoma is not clear. Cystectomy with neoadjuvant or adjuvant chemotherapy appears as a viable option.

The widespread use of the recently introduced multi-detector CT scanners has resulted in an increasing number of incidentally diagnosed pulmonary embolism (PE in asymptomatic cancer patients. The significance and clinical outcome of such incidental PE is described.Methods: Both radiology department and hospital databases were searched for all cancer patients with a diagnosis of incidental PE. CT scans were performed using a 64-slice scanner with a 5.0 mm slice thickness.Results: During the study period, 34 patients with incidental PE were identified. The mean age (±SD was 57.7 (±12.4 years. All patients had active cancer, gastric, lung, colorectal, and lymphomas being the most frequent. Most patients had advanced-stage disease at the time of PE diagnosis; 26 (77% patients had stage IV, whereas only 3 patients had stages I or II disease. Twenty-seven (79% patients had their PE while undergoing active treatment with chemotherapy (68% or radiotherapy (12%; none, however, were on hormonal therapy. Most (74% patients had their PE diagnosed without history of recent hospital admission. Except for 5 (15%, all other patients were anticoagulated. With follow-up, 2 patients developed recurrent PE, 2 others had clinical and echocardiographic evidence of pulmonary hypertension, and 9 (26% died suddenly within 30 days of the diagnosis of incidental PE; 2 of these where among the 5 patients who were not anticoagulated.Conclusion: Incidental PE in cancer patients is increasingly encountered. Similar to symptomatic PE, many were diagnosed in patients with advanced stage disease and while undergoing active anti-cancer therapy.

    Full Text Available Our study addresses the relationship between life experiences, interpretations and the presumed somatic effects in terminal diseases, especially in cancer. The causes and the evolution of cancer were subject in the beginning to experiments and presuppositions, and only later the knowledge began to rely on experimental data and countless case studies. Beside the imperative need to find a treatment, there are numerous questions regarding diagnosis, early intervention or our capacity to do something to prevent the onset of this illness. These questions also include aspects as vulnerabilities, risks and psychological factors. One of the schools of thought that emerged was the psychosomatic medicine, who focused on the relationship between body impact of life experiences and attitudes. Considering this perspective, we searched for individual and social features, and the individual attitudes or beliefs that can be related with the onset or evolution of cancer in a number of cases. Our subjects were 7 patients, diagnosed with cancer, treated in the Palliative Care Unit in Municipal Hospital Pa?cani, Romania. They agreed to participate to the evaluation and to discuss openly their life experiences’ histories. Using a case-study design with qualitative and quantitative measures, our analysis suggest a relationship between characteristics of the lived experiences, personal responses (reaction and the localization and the type of cancer involved.

    Various surveys show that interest in complementary and alternative medicine (CAM) is high among cancer patients. Patients want to explore all options that may help their treatment. Many CAM modalities offer patients an active role in their self-care, and the resulting sense of empowerment is very appealing. On the other hand, many unscrupulous marketeers promote alternative cancer "cures," targeting cancer patients who are particularly vulnerable. Some alternative therapies can hurt patients by delaying effective treatment or by causing adverse effects or detrimental interactions with other medications. It is not in the best interest of cancer patients if they cannot get appropriate guidance on the use of CAM from the health care professionals who are part of their cancer care team. The Integrative Medicine Service at Memorial Sloan-Kettering Cancer Center in New York was established in 1999 to address patient interest in cam, to incorporate helpful complementary therapies into each patient's overall treatment management, to guide patients in avoiding harmful alternative therapies, and to develop prospective research to evaluate the efficacy of CAM modalities.

    Few nursing studies in the past two decades have focused on siblings of children with cancer. Taking care of a hospitalized child with cancer, parents might neglect other children at home. Nursing providers need more information related to siblings and their psychosocial adaptation when one of their children is diagnosed with cancer and undergoing a variety of treatment protocols. The purpose of this study was to explore the changes in the experiences of preschool and school age siblings of children with cancer. A phenomenological study was conducted at a teaching hospital in southern Taiwan. Three children aged between five and nine years old who were siblings of a hospitalized cancer patient were approached in 2003-2004. Their families were also interviewed. Data included in-depth, formal and informal interviews, process recordings, drawings by the children, and a diary of reflections kept by the first author. Interviews lasted between 30 and 90 minutes. The qualitative data analysis method devised by Miles and Huberman (1994) was used. The findings indicated that there were three different changes in experience: Changes in psychological status, i.e., increase in worry about life, anxiety about the disease, and negative self-concepts; Changes in family interaction, i.e., relationship with mother, relationship with father, relationship with other siblings; Changes in social relationship, i.e., hunger for companions, changing recreation. Siblings do experience changes in their lives and may experience mal-adaptation. Nursing providers need to be aware of these changes and identify the health needs among caregivers and siblings of children with cancer. The findings of this study may be helpful to clinical nurses seeking to understand the needs of siblings of children with cancer.

  17. The Struggles of Solidarity: Chicana/o-Mexican Networks, 1960s–1970s

    2015-07-01

    Full Text Available Throughout the 1960s and 1970s, members of the Chicana/o Movement reached across class, borders, and ideologies to proclaim a political solidarity with the Mexican Left. Both, Chicana/os and Mexican activists expressed a narrative of political solidarity that encompassed a perceived shared experience of oppression and struggles for liberation. I contend, however, that both groups saw the source of their oppression and forms of resistance through different lenses. Chicana/o activists identified racism, discrimination, and cultural erasure with oppression, and they retrofit Mexican nationalism with political radicalism. In contrast, Mexican activists celebrated Marxist ideologies as radical political resistance against an increasing authoritarian government and associated Mexican nationalism with state repression and political manipulation.

    Full Text Available Abstract Background Aim of this longitudinal study was to investigate the sensitivity to change of the Swedish Self Evaluation of Communication Experiences after Laryngeal Cancer questionnaire (the S-SECEL, addressing communication dysfunction in patients treated for laryngeal cancer. Previous studies have highlighted the need for more specific questionnaires for this purpose. Methods 100 patients with Tis-T4 laryngeal cancer were included prior to treatment onset. Patients answered four questionnaires at six occasions during one year; the S-SECEL, the European Organisation for Research and Treatment of Cancer (EORTC Core Quality of Life Core Questionnaire (QLQ-C30 supplemented by the Head and Neck cancer module (QLQ-H&N35 and the Hospital Anxiety and Depression (HAD scale. In addition, performance status was assessed. Differences within groups were tested with the Wilcoxon paired signed ranks test and between-group analyses were carried out using the Mann-Whitney U test. Magnitude of group differences was analyzed by means of effect sizes. Results The S-SECEL was well accepted with a response rate of 76%. Communication dysfunction increased at 1 month, followed by a continuous decrease throughout the year. Changes were statistically significant at most measurement, demonstrating the sensitivity of the S-SECEL to changes in communication over time. The S-SECEL and the EORTC QLQ-C30 with the QLQ-H&N35 demonstrated similar results; however the S-SECEL was more sensitive regarding communication dysfunction. The largest changes were found in the most diagnose specific items concerning voice and speech. Conclusion The S-SECEL was investigated in the largest Scandinavian longitudinal study concerning health-related quality of life (HRQL in laryngeal cancer patients. The questionnaire was responsive to change and showed convergent results when compared to established HRQL questionnaires. Our findings also indicate that the S-SECEL could be a more

  1. The Smell of Memories. A Mexican Migrant’s Search for Emotional Sustainability through Mexican Films.

    2011-12-01

    Full Text Available For more than 10 years living as a Mexican migrant, between two countries (Mexico and Australia, two cities (Mexico City and Sydney, and two social worlds (Mexican and multicultural Australian ‘families-friends’, I have been immersed in a systematic process of self observation and self reflection on my life in my country of destination. During this time I have explored my memories of place and their relationship with my emotional experiences, looking for strategies to continue to be connected with my country of origin and my people. In this process I discovered films were especially significant in sustaining me emotionally. I benefited from the memory associations triggered by representations of Mexico in films produced by Mexicans or by filmmakers from other nationalities. By reflecting on my responses to those films, in this paper I explore how representations of their country of origin can impact on migrants’ emotional life. Using autoethnography, examining my own subjectivity as a way to arrive at a deeper grasp of these processes, I analyse the roles played by different senses in the process of recollection and in the emotional effects produced, which come to embody the experience. My particular focus in this article is the sense of smell triggered by complex interactions within the sensorium while watching films, producing associations and feelings through which I re-live my memories and maintain my emotional sustainability.

    Exploring risk factors and profiles of intimate partner violence in other countries provides information about whether existing theories of this phenomenon hold consistent in different cultural settings. This study will present results of a regression analysis involving domestic violence among Mexican women (n = 83,159). Significant predictors of domestic violence among Mexican women included age, number of children in the household, income, education, self-esteem, family history of abuse, and controlling behavior of the husband. Women's employment status was not a significant predictor when all variables were included in the model; however, when controlling behavior of the husband was withdrawn from the model, women's employment status was a significant predictor of domestic violence toward women. Results from this research indicate that spousal controlling behavior may serve as a mediator of the predictive relationship between women's employment status and domestic violence among Mexican women. Findings provide support for continued exploration of the factors that mediate experiences of domestic violence among women worldwide.

Supplemental breast MRI is sometimes used in addition to mammography despite the lack of clinical evidence for it. Breast imaging after cancer treatment is an emotionally charged experience, an important part of survivorship care, and a topic about which limited patient information exists. We assessed women’s experiences and preferences about breast cancer surveillance imaging with the goal of determining where gaps in care and knowledge could be filled. Participants and methods: We conducted six focus groups with a convenience sample of 41 women in California, North Carolina, and New Hampshire (USA. Participants were aged 38–75 years, had experienced stage 0–III breast cancer within the previous 5 years, and had completed initial treatment. We used inductive thematic analysis to identify key themes from verbatim transcripts.

    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).

    The prevalence of thyroid metastases in colorectal cancer (CRC) patients is unknown. We retrieved the records of all patients with CRC and pathologically proved thyroid metastasis for the period 1993-2004. Among 5,862 consecutive patients with CRC, 6 (0.1%) were diagnosed with thyroid metastases, a median of 61 months after the diagnosis of primary tumour, and a median of 19 months after the last surgical resection or radiofrequency ablation of other metastases (which were present in all cases). Signs and symptoms, when present (n=3), consisted of cervical pain, cervical adenopathy, goitre, dysphagia, and/or dysphonia. In other cases, the diagnosis was made by positron emission tomography scanning. Thyroidectomy was performed in the 5 patients with isolated thyroid metastases, with cervical lymph node dissection being required in all cases. The only patient treated conservatively because of concomitant liver and lung metastases developed life-threatening dyspnoea, which required emergent tracheal stenting. Median overall survival was 77 months, 58 months, and 12 months after the diagnosis of primary CRC, initial metastases, and thyroid metastasis, respectively. It is concluded that thyroid metastases are rare and occur late in the course of CRC. Thyroidectomy (with cervical lymph node dissection) may result in prevention or improvement of life-threatening symptoms and prolonged survival.

    Full Text Available Objective: Although much has been documented about the experience of breast cancer, the accounts of young women have been relatively neglected, despite that around 20% of the breast cancer diagnoses occur in women under the age of 50. In particular, the voices of young women diagnosed during pregnancy are missing from research. Breast cancer is the most common cancer associated with pregnancy, and it is diagnosed in about 1 in 3000 pregnancies. Methods: This study presents data from three women drawn from a larger study of women who had been diagnosed under the age of 45 and had completed their treatment for breast cancer. Semi-structured qualitative interviews were undertaken, with a methodology informed by social constructionist grounded theory and feminism. Results: The findings here report the ways that having breast cancer during pregnancy disrupted taken-for-granted assumptions about their pregnancies, new motherhood, and their future life course, and how this occurred within the context of gendered ideas about femininity and motherhood. Conclusions: Breast cancer during pregnancy has a far-reaching impact on young women's lives, and women affected may need practical support in caring for young children, and counselling may be appropriate. Further research is needed in this important area.

    Objective(s): This study addresses feature selection for breast cancer diagnosis. The present process uses a wrapper approach using GA-based on feature selection and PS-classifier. The results of experiment show that the proposed model is comparable to the other models on Wisconsin breast cancer datasets. Materials and Methods: To evaluate effectiveness of proposed feature selection method, we employed three different classifiers artificial neural network (ANN) and PS-classifier and genetic algorithm based classifier (GA-classifier) on Wisconsin breast cancer datasets include Wisconsin breast cancer dataset (WBC), Wisconsin diagnosis breast cancer (WDBC), and Wisconsin prognosis breast cancer (WPBC). Results: For WBC dataset, it is observed that feature selection improved the accuracy of all classifiers expect of ANN and the best accuracy with feature selection achieved by PS-classifier. For WDBC and WPBC, results show feature selection improved accuracy of all three classifiers and the best accuracy with feature selection achieved by ANN. Also specificity and sensitivity improved after feature selection. Conclusion: The results show that feature selection can improve accuracy, specificity and sensitivity of classifiers. Result of this study is comparable with the other studies on Wisconsin breast cancer datasets. PMID:27403253

    This prospective study examined whether the psychological impact of organized mammography screening is influenced by women's pre-existing experience with breast cancer and perceived susceptibility (PS) to the disease. From a target population of 16,886, a random sample of women with a normal...... responded to the follow-ups. Psychological impact was measured as anxiety (STAI-S), depression (BDI), health-related concerns (IAS), and breast cancer-specific beliefs and concerns. Data was analyzed with repeated measures analyses of variance, with estimates of effect size based on Eta-squared. Women...... normal mammograms. Experience and PS did not influence responses to different screening findings. Of the finding groups, false positives experienced most adverse effects: their risk perception increased and they reported most post-screening breast cancer-specific concerns. Furthermore, they became more...

    To evaluate the feasibility of PET/MRI (positron emission tomography/magnetic resonance imaging) with FDG ({sup 18}F-fluorodeoxyglucose) for initial staging of head and neck cancer. The study group comprised 20 patients (16 men, 4 women) aged between 52 and 81 years (median 64 years) with histologically proven squamous cell carcinoma of the head and neck region. The patients underwent a PET scan on a conventional scanner and a subsequent PET/MRI examination on a whole-body hybrid system. FDG was administered intravenously prior to the conventional PET scan (267-395 MBq FDG, 348 MBq on average). The maximum standardized uptake values (SUV{sub max}) of the tumour and of both cerebellar hemispheres were determined for both PET datasets. The numbers of lymph nodes with increased FDG uptake were compared between the two PET datasets. No MRI-induced artefacts where observed in the PET images. The tumour was detected by PET/MRI in 17 of the 20 patients, by PET in 16 and by MRI in 14. The PET/MRI examination yielded significantly higher SUV{sub max} than the conventional PET scanner for both the tumour (p < 0.0001) and the cerebellum (p = 0.0009). The number of lymph nodes with increased FDG uptake detected using the PET dataset from the PET/MRI system was significantly higher the number detected by the stand-alone PET system (64 vs. 39, p = 0.001). The current study demonstrated that PET/MRI of the whole head and neck region is feasible with a whole-body PET/MRI system without impairment of PET or MR image quality. (orig.)

    Full Text Available PURPOSE: Standard treatment for glioblastoma (GBM is surgery followed by radiation (RT and temozolomide (TMZ. While there is variability in survival based on several established prognostic factors, the prognostic utility of other factors such as tumor size and location are not well established. EXPERIMENTAL DESIGN: The charts of ninety two patients with GBM treated with RT at the National Cancer Institute (NCI between 1998 and 2012 were retrospectively reviewed. Most patients received RT with concurrent and adjuvant TMZ. Topographic locations were classified using preoperative imaging. Gross tumor volumes were contoured using treatment planning systems utilizing both pre-operative and post-operative MR imaging. RESULTS: At a median follow-up of 18.7 months, the median overall survival (OS and progression-free survival (PFS for all patients was 17.9 and 7.6 months. Patients with the smallest tumors had a median OS of 52.3 months compared to 16.3 months among patients with the largest tumors, P = 0.006. The patients who received bevacizumab after recurrence had a median OS of 23.3 months, compared to 16.3 months in patients who did not receive it, P = 0.0284. The median PFS and OS in patients with periventricular tumors was 5.7 and 17.5 months, versus 8.9 and 23.3 months in patients with non-periventricular tumors, P = 0.005. CONCLUSIONS: Survival in our cohort was comparable to the outcome of the defining EORTC-NCIC trial establishing the use of RT+TMZ. This study also identifies several potential prognostic factors that may be useful in stratifying patients.

    Phenolic extracts obtained from spices are known to have anti-carcinogenic activities but little is known about the effect of micropropagation on these beneficial effects. The main objective of this study was to evaluate the cytotoxic activity of flavonoid-enriched extracts (FEE) from the leaves of wild (WT), in vitro (IN), and ex vitro (EX) grown oregano plants in colon cancer cells HT-29 and the non-cancer cells CCD-18Co. Cell proliferation of HT-29 cells was reduced to 50 % by WT, IN, and EX at concentrations of 4.01, 1.32, and 4.84 mg of gallic acid equivalents (GAE)/L, respectively. In contrast, in CCD-18Co cells, higher concentrations were required for the same cytotoxic effect. At 6 mg GAE/L, WT and IN reduced the production of reactive oxygen species (ROS) of lipopolysaccharides (LPS)-stimulated control cells to 59.89 and 59.43 %, respectively, and EX to 73.89 %. The mRNA of Caspase-3 was increased 1.53-fold when cells were treated with 4 mg GAE/L of IN extract, and tumor necrosis factor receptor superfamily, member 6 (FAS), and BCL2-associated X protein (BAX) mRNA increased 2.55 and 1.53 fold, respectively. Results on protein expression corroborated the apoptotic effects with a significant decrease of B-cell lymphoma 2 (BCL2) expression for all treatments but more remarkable for EX that also showed the most intense signal of BAX. Overall, FEE extracts derived from micropropagation had increased pro-apoptotic effects, however extracts from the in vitro plants produced more efficacy at the transcriptional level while extracts from the ex vitro plant were superior at the traductional level.

    2016-09-01

    The main purpose of the present study was to understand the subjective experience of patients adjusting to cancer by focusing on how that experience might be affected by participating in a psychodramatic group intervention. In-depth interviews using an interpretative-phenomenological approach were conducted with eight cancer patients involved in a psychodrama group. Four key themes were identified: (1) outside and inside relationships; (2) identities: nurturing other selves; (3) a feelings' gym: performing the internal world; and (4) many ends: mourning death and dying. Participation in cancer group using a psychodramatic approach provided positive results. In detail, the group setting: (1) favoured relationships in which it was possible to freely express oneself and (2) empowered patients in their feelings of being able to give and receive help; the psychodramatic approach: (1) supported the physical mobilisation of sense of agency and (2) permitted to deal with the grieving process. Cancer healthcare pathways would benefit from psychotherapeutic programmes using a similar approach, since psychodrama by actively involving body seems to works on areas that are often underwhelmed by other approaches, such as (i.e., physical mobilisation, body engagement, grieving adjustment). Psychodrama supports patients to achieve insights into their own possibilities to actively participate in their own life situations despite having cancer and undergoing treatment for it.

    Parental cancer during young adulthood is unexpected and potentially disruptive to the developmental goals of this period. This study explores how young adult women experience a parent's cancer diagnosis and treatment. The sample included five participants, aged 20 to 32, who had a parent receiving cancer treatment. The interactive interview format, derived from an autoethnographic approach, allowed the first author (J. P.) to include her own experiences of her mother's cancer in the data. Analysis of the transcribed interviews revealed a number of themes including time, hope and spirituality, the meaning of cancer, relationships, family and coping. Time, an overriding theme in the interviews, is the focus of this article. Sub-themes under time include (1) unexpected timing, (2) uncertainty/waiting, (3) being present, (4) concerns for future, (5) acceleration of time, (6) illness progression and (7) holidays. This research revealed that a daughter's perception of time was altered by her parent's illness, and it also highlighted the significance of parental illness during young adulthood. Practitioners working with this population should be aware of issues related to timing so that daughters can be supported in coping with their parents' illnesses, and in achieving the developmental goals of this transitional phase of the life course.

    Given the rapid growth of the population of cancer survivors, increased attention has been paid to their health problems. Although gastric cancer is one of the most common cancers, empirical evidence of survivorship care is limited. The objectives of this study were to describe the health care status of gastric cancer survivors and to report the experience of using the shared-care model during a one-year experience at the cancer survivorship clinic in Seoul National University Hospital. This is a descriptive, single-center study of 250 long-term gastric cancer survivors who were referred to the survivorship clinic. The status of their health behaviors, comorbid conditions, secondary cancer screenings, and survivorship care status were investigated through questionnaires and examining the medical records. Among the survivors, 7.2% were current smokers, 8.8% were at-risk drinkers, and 32.4% were physically inactive. Among the patients who did not know their bone density status, the majority were in the osteopenic (37.1%) or osteoporotic range (24.1%). Screening among the eligible population within the recommended time intervals were 76.3% for colorectal cancer, but only 13.6% for lung cancer. All of the survivors were provided with counseling and medical management at the survivorship clinic, as appropriate. In conclusion, Long-term gastric cancer survivors have various unmet needs. Shared-care through survivorship clinics can be an effective solution for providing comprehensive care to cancer survivors.

    The organization of cancer detection camps is gaining popularity in our country and it is therefore necessary to evaluate the effectiveness of this approach in the early diagnosis and treatment of cancer. This to our knowledge has not been done. This report analyses an experience in screening for cervical cancer in rural areas of Barsi Tehsil (Maharashtra). The Barsi Tehsil consists of 134 villages with a population of 34,080 women above the age of 30 years (1982-1987). Of these 2,846 were screened through a series of cancer detection camps between 1982 and 1987. The results of the cytological screening in these women have been presented. An evaluation of the camp approach was carried out by the Population based Cancer Registry set up under the National Cancer Registry Programme (Indian Council of Medical Research) in Barsi, Paranda and Bhum tehsils. It was shown that acceptance of cytological screening was poor, thereby indicating that the mere holding of camps was not in itself sufficient to motivate the people, to subject themselves to the Pap smear. Certain suggestions which would appreciably increase the acceptance of cytological screening have been put forward.

    Cancer survivorship is best viewed as a process that continues across the life span. Appraisals of cancer change over time and may not be explicit until long after treatment completion. The current study, using the Lazarus and Folkman (1984) stress-appraisal-coping framework, explored factors related to both a stressful and an irrelevant appraisal of the cancer experience by older long-term survivors. Hierarchical regression analysis investigated the individual and cumulative effects of person factors (survivors' demographic characteristics, beliefs about the effect of cancer on family members) and situation factors (characteristics of cancer) on survivors' appraisals that cancer was a stressful life event. The strongest correlates of the stress appraisal were person factors. A more stressful appraisal was associated with: (1). the belief that diagnosis/treatment caused greater family distress, (2). being younger, and (3). being White. The irrelevant appraisal had a marginally significant correlate in bivariate analysis and was not included in regression analysis. Implications for health-care professionals and patient/family interventions are discussed.

    Full Text Available To manage a metastatic cancer patient in a rural setting is a daunting task owing to the lack of resources and infrastructure. Intravenous chemotherapy (CT, with its debilitating side effects, often causes a decrease in the quality of life (QOL of the patient. When the treatment is of palliative intent, efforts should be made to provide maximum symptom relief to the patient, striking a balance between the patient’s wishes and a sound scientific rationale. We describe our experience with a patient with extensively metastatic breast cancer treated in our rural center with single-agent oral capecitabine, without development of any severe toxicity and with a significant improvement in disease process and patient’s performance status (PS.

    The objectives of this meta-synthesis were to: (1) explore the experience of caregivers who were caring for cancer patients, including their perceptions and responses to the situation; and (2) describe the context and the phenomena relevant to the experience. Five databases were used: CINAHL, MEDLINE, Academic Search, Science Direct, and a Thai database known as the Thai Library Integrated System (ThaiLIS). Three sets of the context of the experience and the phenomena relevant to the experience were described. The contexts were (1) having a hard time dealing with emotional devastation; (2) knowing that the caregiving job was laborious; and (3) knowing that I was not alone. The phenomenon showed the progress of the caregivers’ thoughts and actions. A general phenomenon of the experience—balancing my emotion—applied to most of the caregivers; whereas, more specific phenomenon—keeping life as normal as possible and lifting life above the illness—were experienced by a lesser number of the caregivers. This review added a more thorough explanation of the issues involved in caregiving for cancer patients. A more comprehensive description of the experience of caregiving was described. The findings of this review can be used to guide clinical practice and policy formation in cancer patient care. PMID:26610573

    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.

    Objective To test whether there is an association between abortion legislation and maternal mortality outcomes after controlling for other factors thought to influence maternal health. Design Population-based natural experiment. Setting and data sources Official maternal mortality data from 32 federal states of Mexico between 2002 and 2011. Main outcomes Maternal mortality ratio (MMR), MMR with any abortive outcome (MMRAO) and induced abortion mortality ratio (iAMR). Independent variables Abortion legislation grouped as less (n=18) or more permissive (n=14); constitutional amendment protecting the unborn (n=17); skilled attendance at birth; all-abortion hospitalisation ratio; low birth weight rate; contraceptive use; total fertility rates (TFR); clean water; sanitation; female literacy rate and intimate-partner violence. Main results Over the 10-year period, states with less permissive abortion legislation exhibited lower MMR (38.3 vs 49.6; p<0.001), MMRAO (2.7 vs 3.7; p<0.001) and iAMR (0.9 vs 1.7; p<0.001) than more permissive states. Multivariate regression models estimating effect sizes (β-coefficients) for mortality outcomes showed independent associations (p values between 0.001 and 0.055) with female literacy (β=−0.061 to −1.100), skilled attendance at birth (β=−0.032 to −0.427), low birth weight (β=0.149 to 2.166), all-abortion hospitalisation ratio (β=−0.566 to −0.962), clean water (β=−0.048 to −0.730), sanitation (β=−0.052 to −0.758) and intimate-partner violence (β=0.085 to 0.755). TFR showed an inverse association with MMR (β=−14.329) and MMRAO (β=−1.750) and a direct association with iAMR (β=1.383). Altogether, these factors accounted for (R2) 51–88% of the variance among states in overall mortality rates. No statistically independent effect was observed for abortion legislation, constitutional amendment or other covariates. Conclusions Although less permissive states exhibited consistently lower maternal mortality

    2016-05-01

    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.

    Background Net survival rates of cancer are increasing worldwide, placing a strain on health service provision. There is a drive to transfer the care of cancer survivors—individuals living with and beyond cancer—to the community and encourage them to play an active role in their own care. Telehealth, the use of technology in remote exchange of data and communication between patients and health care professionals (HCPs), is an important contributor to this evolving model of care. Telehealth interventions are “complex,” and understanding patient experiences of them is important in evaluating their impact. However, a wider view of patient experience is lacking as qualitative studies detailing cancer survivor engagement with telehealth are yet to be synthesized. Objective To systematically identify, appraise, and synthesize qualitative research evidence on the experiences of adult cancer survivors participating in telehealth interventions, to characterize the patient experience of telehealth interventions for this group. Methods Medline (PubMed), PsychINFO, Cumulative Index for Nursing and Allied Health Professionals (CINAHL), Embase, and Cochrane Central Register of Controlled Trials were searched on August 14, 2015, and March 8, 2016, for English-language papers published between 2006 and 2016. Inclusion criteria were as follows: adult cancer survivors aged 18 years and over, cancer diagnosis, experience of participating in a telehealth intervention (defined as remote communication or remote monitoring with an HCP delivered by telephone, Internet, or hand-held or mobile technology), and reporting qualitative data including verbatim quotes. An adapted Critical Appraisal Skill Programme (CASP) checklist for qualitative research was used to assess paper quality. The results section of each included article was coded line by line, and all papers underwent inductive analysis, involving comparison, reexamination, and grouping of codes to develop descriptive themes

    Objective to comprehend the psychosocial and cultural repercussions of breast cancer and its treatment on the sexuality of women. Method this is a qualitative study grounded in the Sexual Scripts Theory with the participation of 23 women who were interviewed and participated in focus groups discussion. Results each category was related to a level of the sexual scripts. At the cultural scenario level a discourse on sexuality that includes definitions of sexual attractiveness and sexuality was highlighted. The interpersonal scripts level focused on the communication regarding sexuality established with the partner and with healthcare professionals category; and at the subjectivity scripts level the reports of improvement, deterioration and no change in the sexual life after cancer were analyzed. Conclusion the experience of cancer involves cultural, relational, and subjective aspects that affect the sexual life, therefore, healthcare professionals should be aware of them to improve integral healthcare.

    2000-01-01

    Cancer illness affects people in many ways, physical, financial, and existential. In this paper, we describe a proposed group intervention for individuals with advanced disease who want help finding a sense of meaning at this critical juncture in their lives. This intervention has a brief, semi-structured format, and is informed by the work of Viktor Frankl, empirical findings in the area of meaning and trauma, and the empirical findings of other group interventions for cancer patients. Individual sessions focus on different aspects of meaning, including responsibility to others, creativity, transcendence, and ascertaining one's values and priorities. Having goals on which to focus and feeling like part of a larger whole are critically important to the ability to find meaning and cope with terminal illness. Such goals may be generated by a number of sources, including connectedness with others, or a sense of the temporal continuity of one's own life despite the disruption posed by severe illness. Didactic discussions and experiential exercises help to facilitate exploration of these various elements in group members' lives. The finite structure of the intervention may also highlight these issues, as people who are faced with similar issues work together in a limited time frame in order to accomplish the goals they set out for themselves.

    Prostate cancer is a significant cause of morbidity and mortality in men in all adult life stages. Normative developmental tasks of aging combined with disease-related stressors may negatively affect adjustment to prostate cancer and, consequently, affect the quality of life of both the man and his spouse. The purpose of this study was to examine the experiences of men with prostate cancer and their partners according to their life cycle cohort: 50-64 (late middle age), 65-74 (young-old), and 75-84 (old-old). Qualitative interviews with 15 couples were used to provide information about the dyad's experiences with prostate cancer. Interview data were analyzed to identify preliminary coding schemas, which were subsequently refined and modified into themes. Three major themes were identified from the data. Across all age groups, prostate cancer had a significant effect on: (1) couples' daily lives, (2) their dyadic and family relationships, and (3) their developmental stage. There were also differences in age groups. Couples in the late middle age group reported greater disappointment and anger at their inability to reach life goals and establish financial security. Couples in the young-old group made more spontaneous comments about being satisfied with their life than the couples in the other 2 groups. Couples in the old-old group reported slower recovery from the illness than the younger couples. Results indicate that although prostate cancer may have some universal effects on couples, it also may have differential effects by age cohort. Hence, targeted interventions by age cohort may be warranted.

    Full Text Available Background: Cancer pain is a complex multidimensional construct. Physicians use a patient-centered approach for its effective management, placing a great emphasis on patient self-reported ratings of pain. In the literature, studies have shown that a patient′s ethnicity may influence the experience of pain as there are variations in pain outcomes among different ethnic groups. At present, little is known regarding the effect of ethnicity on the pain experience of cancer patients; currently, there are no systematic reviews examining this relationship. Materials and Methods: A systematic search of the literature in October 2013 using the keywords in Group 1 together with Group 2 and Group 3 was conducted in five online databases (1 Medline (1946-2013, (2 Embase (1980-2012, (3 The Cochrane Library, (4 Pubmed, and (5 Psycinfo (1806-2013. The search returned 684 studies. Following screening by inclusion and exclusion criteria, the full text was retrieved for quality assessment. In total, 11 studies were identified for this review. The keywords used for the search were as follows: Group 1-Cancer; Group 2- Pain, Pain measurement, Analgesic, Analgesia; Group 3- Ethnicity, Ethnic Groups, Minority Groups, Migrant, Culture, Cultural background, Ethnic Background. Results: Two main themes were identified from the included quantitative and qualitative studies, and ethnic differences were found in: (1 The management of cancer pain and (2 The pain experience. Six studies showed that ethnic groups face barriers to pain treatment and one study did not. Three studies showed ethnic differences in symptom severity and one study showed no difference. Interestingly, two qualitative studies highlighted cultural differences in the perception of cancer pain as Asian patients tended to normalize pain compared to Western patients who engage in active health-seeking behavior. Conclusion: There is an evidence to suggest that the cancer pain experience is different between

    Full Text Available Siwan Seaman,1 Annmarie Nelson,2 Simon Noble2 1Department of Palliative Medicine, Royal Gwent Hospital, Newport, Wales, UK; 2Marie Curie Palliative Care Research Unit, Cardiff University, Cardiff, Wales, UK Background: Venous thromboembolism is a common complication of cancer and its treatments. Treatment of cancer-associated thrombosis (CAT differs from treatment of thrombosis in noncancer patients, requiring a daily injection of low-molecular-weight heparin (LMWH for 6 months instead of an oral anticoagulant. Previous research suggested LMWH is an acceptable intervention in the treatment of CAT, yet clinical practice and therapeutic opportunities have changed in the decade since the study was conducted. Furthermore, in the previous study there was acknowledged selection bias in participant recruitment. There is increasing clinical use of the novel oral anticoagulants, although their efficacy and safety is yet to be demonstrated within the cancer population. The experience of patients receiving anticoagulation for CAT will inform future practice with respect to quality of life and adherence to anticoagulation therapy. Aim: To explore the acceptability of long-term LMWH for the treatment of CAT in the contexts of living with cancer and quality of life. Design: Qualitative study of cancer patients who had been receiving LMWH for at least 3 months for CAT was undertaken. Audiotaped semistructured interviews were conducted and transcribed. Thematic analysis was undertaken until theoretical saturation. Setting/participants: Fourteen patients attending a palliative care or CAT clinic were interviewed. Participants had been receiving LMWH for a median 6 months. Results: Participants reported distressing symptoms associated with symptomatic CAT, which they rated as worse than their cancer experiences. LMWH was considered an acceptable intervention despite challenges of long-term injections. Several adaptive techniques were reported to optimize ongoing

    Objective: This study sought to explore the experience of people with a diagnosis of cancer while attending for imaging procedures. The diversity and complexity of the issues described within individual interviews made it impossible to include all cancer groups in one paper. This paper focuses on the cohort of men with prostate cancer. Method: An opportunistic sample of men (n = 8) were recruited from Cancer Support Groups throughout the North-east of Scotland. A qualitative, exploratory and retrospective study design was employed using semi-structured interviews. All interviews were audio taped and full transcripts produced. These were analysed following the recommendations of Miles and Huberman (1994). Main findings: Men were keen to take part in the study, and described experiences from pre-diagnosis to the date of interview. Participants reported different routes to diagnosis, then having a range of diagnostic procedures indicating a very personal journey with no standardised approach. Imaging was not seen as a separate event but part of the whole story. The provision of radiology patient information material was haphazard. Participants could explain why they were having these procedures, and saw them as a 'necessary evil'. The provision of results of their tests was complex and chaotic, and was described as an anxious time. Conclusion: This study provides a unique insight into the experiences of men with prostate cancer relating to their attendance for imaging. Health professionals need to listen to their patients and learn, in order to provide a high quality, patient-centred imaging service.

    Ibervillea sonorae Greene, Cucurbita ficifolia Bouché, Tagetes lucida Cav and Justicia spicigera Scheltdd are Mexican native plants used in the treatment of different illnesses. The ethanolic extract of J. spicigera and T. lucida as well as aqueous extracts from I. sonorae, C. ficifolia, T. lucida and J. spicigera were investigated using sulforhodamine B assay. These extracts were assessed using two cell line: T47D (Human Breast cancer) and HeLa (Human cervix cancer). Colchicine was used as the positive control. Data are presented as the dose that inhibited 50% control growth (ED50). All of the assessed extracts were cytotoxic (ED50 < 20 microg/ml) against T47D cell line, meanwhile only the aqueous extract from T. lucida and the ethanolic extract from J. spicigera were cytotoxic to HeLa cell line. Ethanolic extract from J. spicigera presented the best cytotoxic effect. The cytotoxic activity of J. spicigera correlated with one of the popular uses, the treatment of cancer.

    two Nasmyth focal stations are contemplated, nominally with focal ratios of f/5 and f/11. The concept will allow the use of existing instruments like MMIRS and MEGACAM. Available experience from currently working ground-based telescopes will be integrated with up-to-date technology specially for control and information management systems. Its mount is the well-known azimuth-elevation configuration. The telescope total mass is estimated in about 245 metric tons, with a total azimuth load of 185 metric tons including around 110 metric tons as the total elevation load. A tracking error lower than 0.03 arcsec RMS is expected under steady wind up to 50 Km/h. An open-loop pointing accuracy between 10 and 2 arcsec is planned. The TSPM is in its design phase. It is the first large optical ground-based telescope to be designed and developed primarily by Mexican scientists and engineers. This endeavor will result in the improvement of the scientific and technical capabilities of Mexico including complex scientific instruments development, systems engineering and project management for large engineering projects. In this paper, which aims to gather the attention of the community for further discussions, we present the engineering preliminary design, the basic architecture and challenging technical endeavors of the TSPM project.

    2016-04-01

    Cachexia is one of the most widely overlooked of the syndromes that are experienced by cancer patients. This syndrome is especially prevalent among patients with gastroenterology tract cancer. Although the National Comprehensive Cancer Network (NCCN) issued palliative-care practice guidelines for cachexia in 2015, guidelines have yet to be issued for the clinical setting. The authors reviewed the literature and applied their clinical experience to create an approach for identifying the degree of cachexia in a post-operative patient with periampullary cancer. This approach assesses the nutritional status, physical status, laboratory results, and gastrointestinal system functions of the patient using the Cachexia Assessment Scale (CAS) and NCCN Practice Guidelines for Cachexia. The patient improved under nursing care with an increase in nutritional intake and physical activity facilitating their process of post-surgical physical recovery. The authors hope that this experience using the combined CAS-NCCN Practice Guidelines will help clinical caregivers better understand how to apply the relevant guidelines in clinical settings. The developed approach may help nurses assess the comprehensive nutrition status of patients and related factors in order to provide interventions that will decrease the progression of cachexia effectively and promote quality of life.

Qualitative (n=77 and quantitative (n=422 methods such as focus groups, interviews and self-administered questionnaires were used. Qualitative analysis showed that patients faced difficulties navigating a complex and fragmented healthcare system.Results: Mechanisms to overcome barriers included informal routes such as personal relationships, coordinating roles by nurse coordinators and the patients' general practitioners (GPs. The most significant variable was GPs involvement, which affected transition process quality as rated on the CTM (p<0.001. Our findings point to the important interpersonal role of oncology nurses to coordinate and facilitate the care transition process.Conclusion: Interventions targeted towards supporting the care transition process should emphasize ongoing counseling throughout a patient’s care, during and after hospitalization.-----------------------------------------Cite this article as:  Admi H, Muller E, Shadmi E.

  8. Radiofrequency Ablation of Lung Cancer at Okayama University Hospital: A Review of 10 Years of Experience

    Directory of Open Access Journals (Sweden)

    Hiraki,Takao

    2011-10-01

    Full Text Available The application of radiofrequency ablation for the treatment of lung cancer by our group at Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences began in June 2001, and in the present report, we review our 10-year experience with this treatment modality at Okayama University Hospital. The local efficacy of radiofrequency ablation for the treatment of lung cancer depends on tumor size and the type of electrode used, but not on tumor type. An important factor for the prevention of local failure may be the acquisition of an adequate ablative margin. The combination of embolization and radiation therapy enhances the local efficacy. Local failure may be salvaged by repeating the radiofrequency ablation, particularly in small tumors. Survival rates after radiofrequency ablation are quite promising for patients with clinical stage I non-small cell lung cancer and pulmonary metastasis from colorectal cancer, hepatocellular carcinoma, and renal cell carcinoma. The complications caused by radiofrequency ablation can be treated conservatively in the majority of cases. However, attention should be paid to rare but serious complications. This review shows that radiofrequency ablation is a promising treatment for patients with lung cancer.

    A growing emphasis on patient self-advocacy has emerged in the public discourse on cancer survivorship. This discourse shapes patients' conceptualizations about self-advocacy and in turn influences their health care attitudes and behaviors. The purpose of this discourse analysis is to explore the language of self-advocacy by comparing a published self-advocacy guide with the lived experiences of women with ovarian cancer. Data sources include (1) a self-advocacy patient education guide published by the National Coalition for Cancer Survivorship and (2) transcripts of focus groups conducted with ovarian cancer survivors. Discourse analysis techniques were used to take a close look at the language used by both to uncover the meaning each group ascribed to self-advocacy. Challenges and inconsistencies were noted between the patient education guide and transcripts including viewing self-advocacy as a skill set to assert one's needs as opposed to a means by which to preserve a positive attitude and maintain a trusting relationship with health care providers, respectively. Some women saw themselves as self-advocates yet struggled to locate relevant health information and hesitated to upset their relationship with their health care providers. This analysis highlights tensions between the discourses and points to ways in which patient education materials can be adjusted to support cancer survivors in advocating for their needs according to their unique situations and preferences.

    Throughout the 1960s and 1970s, members of the Chicana/o Movement reached across class, borders, and ideologies to proclaim a political solidarity with the Mexican Left. Both, Chicana/os and Mexican activists expressed a narrative of political solidarity that encompassed a perceived shared experience of oppression and struggles for liberation. I contend, however, that both groups saw the source of their oppression and forms of resistance through different lenses. Chicana/o activists identifie...

    Children and adolescents with cancer are increasingly treated and cared for at home; hospital stays are reduced to a minimum. Taking care of a sick child at home has an impact on the entire family: the sick child, the siblings, and the parents. This qualitative study examines the experiences of parents taking their child home for the first time after the diagnosis. Parents of 10 children newly diagnosed with cancer were interviewed twice around the time of the first discharge; data were analyzed using content analysis methodology. Findings illustrated parents' preparation of and experiences around their child's first discharge, the huge amount of new and changed tasks parents have to fulfill at home when caring for their child with cancer, and consequences for the parents. By providing individualized information and instruction, by having parents anticipate potential problems and solutions, and by describing available community support and integrating district nurses as well as other parents with the same experiences more frequently, health care professionals in the hospital can optimize discharge planning for these parents.

    Full Text Available Venous invasion (VI is a well-established independent prognostic indicator in colorectal cancer (CRC. Its accurate detection is particularly important in stage II CRC as it may influence the decision to administer adjuvant therapy. The Royal College of Pathologists (RCPath of the United Kingdom state that VI should be detected in at least 30% of CRC resection specimens. However, our experience in Ontario, Canada suggests that this (conservative benchmark is rarely met. This article highlights the Ontario experience with respect to VI reporting and the key role that careful morphologic assessment, elastin staining and knowledge transfer has played in improving VI detection provincially and beyond.

    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.

    Background: Breast cancer survivors make up a growing population facing treatment that poses long-standing adverse effects including chemotherapy-related body function changes and/or pain. There is limited knowledge of patients’ lived experiences of chemotherapy-induced pain (CHIP). Objective: The aim of this study was to explore CHIP and any long-standing pain experiences in the lifeworld of breast cancer survivors. Methods: Fifteen women participated in a follow-up interview a year after having experienced CHIP. They were interviewed from a lifeworld perspective; the interviews were analyzed through guided phenomenology reflection. Results: A past perspective: CHIP is often described in metaphors, leads to changes in a patient’s lifeworld, and impacts lived time. The women become entirely dependent on others but at the same time feel isolated and alone. Existential pain was experienced as increased vulnerability. Present perspective: Pain engages same parts of the body, but at a lower intensity than during CHIP. The pain creates time awareness. Expected normality in relationships/daily life has not yet been achieved, and a painful existence emerges in-between health and illness. Future perspective: There are expectations of pain continuing, and there is insecurity regarding whom to turn to in such cases. A painful awareness emerges about one’s own and others’ fragile existence. Conclusions: Experiencing CHIP can impact the lifeworld of women with a history of breast cancer. After CHIP, there are continued experiences of pain that trigger insecurity about whether one is healthy. Implications for Practice: Cancer survivors would likely benefit from communication and information about and evaluation of CHIP. PMID:26632880

    The aim was to synthesise patients’ and relatives’ experiences of participating in a psychosocial intervention related to having cancer. The study was a meta-synthesis inspired by Noblit & Hare’s ‘meta-ethnography’ approach. We systematically searched six databases and included 33 studies...... symbolising the participants’ core experiences were identified: 1) Emotional relief and a sense of well-being, 2) normalisation of experiences and a sense of control, 3) shared experience and a sense of community, 4) a safe place and 5) transformation and adaptability. The findings indicated that psychosocial...... interventions were used to try to deal with the changes in the human conditions caused by cancer. Sharing their experiences and forming social relationships helped the participants adapt to cancer. An existential perspective may provide a nuanced understanding of patients’ and relatives’ experiences...

    The aim of this review was to identify the factors associated with positive experiences in non-professional carers of someone with a cancer diagnosis. A systematic search of the following electronic databases was undertaken: Cochrane Library, CINAHL, PsycINFO, SocINDEX and Medline. Literature was searched using terms relating to cancer, caring and positive experiences. Additional records were identified through a manual search of relevant reference lists. The search included studies published in English from 1990 to June 2015. Two raters were involved in data extraction, quality appraisal, coding, synthesis and analysis. Evolutionary concept analysis was used as a guiding framework in order to focus on attributes associated with positive experiences. Fifty-two articles were included in this review. Analysis identified four overarching attributes: "gender," "personal resources," "finding meaning" and "social context." Despite the challenges associated with caring, this combination of internal and external factors enabled some carers to report positive experiences related to caring. This knowledge may be clinically helpful when designing supportive interventions. Strengths and limitations of these claims are discussed. Systematic review registration number: CRD42014014129.

    When a child is ill with cancer, this affects the whole family for long periods. The aim of this study was to elucidate the family's lived experience when a child in the family was diagnosed with cancer. A descriptive inductive design with a hermeneutic phenomenological approach including interviews with 17 families (parents, children, and siblings) was chosen. The families' lived experience was described as a 2-fold essential theme comprising "a broken life world" and an immediate "striving to survive." The families' secure everyday life disappeared and was replaced by fear, chaos, and loneliness. When striving to make the child and the family survive, family members strove to feel hope and have a positive focus, to gain control, and to feel close to other people. Phenomenological human science research can deepen the understanding of the meaning of being a family with a child who is ill with cancer and can help pediatric oncology staff become increasingly thoughtful, and thus better prepared to take action to diminish the chaos occurring in the family.

    Full Text Available Purpose:- To know the experiencies and perceived needs of children and teenagers with cancer and their care givers regarding the received care and their oncological process. - To identify proposals for improving care.Methodology: A qualitative study based on individual semistructured interviews and focus interviews with children and teenagers diagnosed of cancer was designed. Results: Hospitalization, therapeutic and diagnose procedures, side effects and isolation when neutropenia, were identified as the main traumatic experiencies suffered by children and relatives. These issues were related to physic, psycologic, social and educational problems. Mothers showed sad and other depression feelings, although those feelings changed as the process of the illness evolved. Some improvement proposals were made by relatives, including the need of a better correlation between health resources and patient/relatives needs. The proffesional support and the care received were given great value.Conclusions: The illness was associated to physic, psycologic and social consequencies for both patients and relatives. Taking their opinion into account is very useful to improve the quality of the health servicies offered to children with cancer and their family.

    Latinos in the United States have been disproportionately affected by the HIV epidemic. The purpose of this study was to identify potential themes for inclusion in effective HIV prevention interventions for Mexican American men who have sex with men (MSM). The authors used a phenomenological design to explore the lived experiences of Mexican American MSM who had grown up in Dallas, Texas, regarding protective factors for HIV infection. A total of 20 30- to 60-year-old Mexican American MSM participated in semistructured interviews. During data analysis, the following themes concerning protective behaviors for HIV emerged: (a) accepting one's sexuality; (b) machismo; (c) being in love; (d) respect for family, self, and life; and (e) having HIV-living now. Strategies for potential inclusion in HIV prevention interventions geared toward Mexican American MSM were identified based on these themes. The recommendations encompass modification of behavioral interventions and related social policies.

    Advances in cancer treatment allow women to be cured and live longer. However, the necessary chemotherapy and radiotherapy regimens have a negative impact on future fertility. Oncofertility has emerged as a new interdisciplinary field to address the issue of gonadotoxicity associated with cancer treatment and to facilitate fertility preservation, including oocyte and ovarian tissue cryopreservation. These fertility issues are often inadequately addressed, and referral rates to oncofertility centers are low. The aim of this study was to report the 3-year experience of the San Raffaele Oncofertility Unit. A total of 96 patients were referred to the Oncofertility Unit for evaluation after the diagnosis of cancer and before gonadotoxic treatment between April 2011 and June 2014. Of the 96 patients, 30 (31.2%) were affected by breast cancers, 20 (20.8%) by sarcomas, 28 (29.2%) by hematologic malignancies, 13 (13.5%) by central nervous system cancers, 3 (3.1%) by bowel tumors, 1 (1.0%) by Wilms’ tumor, and 1 (1.0%) by a thyroid tumor; 47 (49.0%) were referred for oocyte cryopreservation before starting chemotherapy, 20 (20.8%) were referred for ovarian tissue cryopreservation, and 29 (30.2%) were not recruited. The mean time between the patients’ counseling and oocyte retrieval was 15 days (range, 2–37 days). The mean time between the laparoscopic surgery and the beginning of treatment was 4 days (range, 2–10 days). The number of patients who were referred increased over time, whereas the rate of patients who were not recruited decreased, showing an improvement in referrals to the Oncofertility Unit and in the patients’ counseling and understanding. Our results indicate that an effective multidisciplinary oncofertility team is necessary for prompt referrals and treatment.

    Background In the People’s Republic of China, both western medicine (WM) and traditional Chinese medicine (TCM) are the main treatment and rehabilitation options for cancer patients. This study aimed to explore cancer survivors’ perspectives and experience of treatment and rehabilitation, in order to promote patient-centered activities of treatment and rehabilitation. Methods Using a qualitative research approach, 68 cancer survivors were recruited from eight community cancer rehabilitation organizations in Shanghai, People’s Republic of China. Eight focus group interviews were conducted. All these interviews were transcribed verbatim, and the data were analyzed by theme analysis. Results WM was the main choice in treatment phase though study participants noted more side effects. TCM was primarily used in the recovery phase. The lack of communication between doctors and cancer patients appears to affect treatment adherence and impair the doctor–patient relationship. WM was expensive for diagnostic procedures and treatment, while the cumulative costs of frequent use of TCM in the long rehabilitation period were also high. Both treatment options created significant perceived economic burden on patients. Conflicting information about dietary supplements tended to make cancer survivors confused. Conclusion Improving the communication between doctors and cancer patients helps to ameliorate cancer patient adherence and the effect of treatments. It is essential to educate cancer patients about the effect and cost of both WM and traditional TCM. Meanwhile, marketing management and guidance to consumers regarding use of dietary supplements in the cancer rehabilitation field are also necessary. PMID:25565779

    Objective: To explore the diagnosis and treatment experience of breast cancer associated with pregnancy or lactation. Methods: From January 1990 to December 2005, 14 cases with breast cancer associated with pregnancy or lactation were analyzed retrospectively (TNM stage Ⅱ, 2 cases; stage Ⅲ, 11 cases; stage Ⅳ, 1 case). Diagnosis was established by fine needle aspiration biopsy primarily or routine pathological method if necessary. Abortion was used for discontinuation of pregnancy in 1 case with early pregnancy and 1 case with meddle pregnancy. 2 patients with late pregnancy received cesarean section,10patients of breast cancer associated with lactation received multidisciplinary and-tumor treatment after discontinuation of lactation. Results: Diagnosis was confirmed by fine noodle aspiration biopsy in 9 cases and by secondary routine pathological method in the other 5 cases, 12 cases were followed up, 1 case of stage Ⅳ died of metastasis 5 months after diagnosis. 3-, 5-year survival rates in 10 cases of stage Ⅲ were 66% and 30% respectively. One case remained alive without recurrence for 8 years up to now. Conclusion: A thorough breast examination is necessary at the first antenatal visit physicians should aggressively pursue work-up in women with a palpable breast tass. In the patients during the second and third trimness,the various modalities available for treatment inholding abortion and their risks and beneath modalities available for treatment including abortion and their risks and benefits must be discussed openly with patients and their families.

    Full Text Available Abstract. There are evidences of increasing cervix uteri malignant tumors in the Republic of Sakha (Yakutia in the period of 2003–2013. In such situation new, more effective, but less expensive organizational measures for prevention and early identification of oncological diseases should be developed. The recent epidemiological studies have convincingly shown that high-oncological-risk genital papilloma viral infection was certain risk factor of developing pre-cancer changes and cervical cancer. Detection of HPV regional epidemiological characteristics is extremely important for optimization of programs on diagnostics and prevention of cervix uteri cancer. The epidemiological and molecular-biological studies in Yakutia have detected more high infection rate in the female population than in male one. It was established that 11 high-oncological-risks genotypes of the virus circulating in the region with considerable prevalence of HPV Type 16. Since 2008 the program on vaccination against papilloma viral infection for girls and young women aged 10 to 25 years has been implemented in Yakutia Over six years, the number of vaccinated girls and women in Yakutsk reached 1093 persons. It has been the first experience in the Siberian and Far Eastern Federal Regions.

    BACKGROUND: Continuous stimulation of the androgen receptor (AR) axis is a prerequisite for growth in castration-resistant prostate cancer (CRPC). Abiraterone acetate (AA) is a potent inhibitor of extracellular and intracellular androgen synthesis by inhibition of the CYP-17 enzyme system, which...... has been shown to be up-regulated in CRPC. AA was recently introduced in the management of patients with metastatic CRPC (mCRPC) both before and after taxane-based chemotherapy. The purpose of this study is to report the initial clinical experience obtained from mCRPC patients managed on AA......% of the patients. Time to biochemical and radiological progression was 3.5 and 4.9 months, respectively. Overall survival was 13.2 months (95% CI: 9.0-17.4). CONCLUSION: Our initial experience with AA in the routine management of patients with mCRPC demonstrates an efficacy-effectiveness gap compared with clinical...

    Empirical research on biculturalism is limited, in part because of the lack of quality measures of biculturalism. The currently available measures have limitations due to scoring procedures and sampling of only a narrow range of behaviors and attitudes. We present a measure of biculturalism that captures a broader range of the bicultural experience and uses a scoring system that better represents the wide ranging levels of biculturalism that exist in the diverse population of Mexican American adolescents, mothers, and fathers born in either Mexico or the United States. The Mexican American Biculturalism Scale (27 items) includes 3 subscales: bicultural comfort (9 items), bicultural facility (9 items), and bicultural advantages (9 items). We report on the reliability and construct validity of test scores and present confirmatory factor analyses findings for a diverse sample of 316 Mexican American families from a large southwestern metropolitan city. The Mexican American Biculturalism Scale is available in English and in Spanish. The use of the scale has implications for future research studying how biculturalism is related to psychological outcomes for Mexicans/Mexican Americans.

    2012-01-01

    Recently,novel anti-androgens and inhibitors of androgen biosynthesis have been developed through the elucidation of mechanisms of castration resistance of prostate cancer.We believe that these new developments will improve hormonal therapy.On the other hand,there has been an increase in criticism of hormonal therapy,because hormonal therapy is supposed to induce adverse effects such as cardiovascular disease.In this review,we have introduced the Japanese experience of hormonal therapy,because we believe that there may be ethnic differences between Caucasians and Asian people in the efficacy and adverse effects of hormonal therapy.First,we showed that primary hormonal therapy can achieve long-term control of localized prostate cancer in some cases and that quality of life of patients receiving hormonal therapy is rather better than previously thought.Neoadjuvant and adjuvant hormonal therapy in cases undergoing radical prostatectomy or radiotherapy are very useful for high-risk or locally advanced prostate cancer.Further clinical trials are required to confirm the efficacy of neoadjuvant or adjuvant hormonal therapy.We showed that the death from cardiovascular diseases in Japanese patients receiving hormonal therapy was not higher than that in the general population.However,efforts should be made to decrease the adverse effects of hormonal therapy,because life-style change may increase the susceptibility to adverse effects by hormonal therapy even in Japan.Managements of endocrine and metabolic dysfunction,such as diabetes mellitus,are essential.New hormonal compounds such as selective androgen receptor modulators capable of specifically targeting prostate cancer are expected to be developed.

    2016-01-01

    Full Text Available Urinary bladder cancer (UBC is one of the most common cancers, with 1 out of every 26 men and 1 out of every 80 women worldwide developing the disease during their lifetime. Moreover, it is a disease that predominantly affects the elderly and is becoming a major health problem as the elderly population continues to rapidly increase. In spite of the rapid development of medical science, the 5-year survival rate has remained around 75% since the 1990s, and the FDA has approved no new drugs for UBC over the last 10 years. In addition, most patients experience frequent recurrence and poor quality of life after diagnosis. Therefore, in order to solve unmet needs by alternative methods, we present our clinical cases of UBC where we observed outstanding results including regression and recurrence prevention exclusively through Traditional Korean Medicine such as (1 herbal therapy, (2 acupuncture, (3 pharmacopuncture and needle-embedding therapy, (4 moxibustion, and (5 cupping therapy. From our experience, it appears that multimodal strategies for synergistic efficiency are more effective than single Korean Medicine treatment. We hope this will encourage investigation of the efficacy of Korean Medicine treatment in clinical trials for UBC patients.

    Objective Despite the importance of parenting-related responsibilities for adult patients with terminal illnesses who have dependent children, little is known about the psychological concerns of dying parents and their families at the end of life (EOL). The aim of this study was to elicit widowed fathers’ perspectives on how parental status may have influenced the EOL experiences of mothers with advanced cancer. Subjects Three hundred and forty-four men identified themselves through an open-access educational website as widowed fathers who had lost a spouse to cancer and were raising dependent children. Methods Participants completed a web-based survey about their wife’s EOL experience and cancer history, and their own depression (Center for Epidemiologic Studies Depression Scale, CES-D) and bereavement (Texas Revised Inventory of Grief, TRIG) symptoms. Descriptive statistics, Fisher’s exact tests, and linear regression modeling were used to evaluate relationships between variables. Results According to fathers, 38% of mothers had not said goodbye to their children before death and 26% were not at all “at peace with dying.” Ninety percent of widowed fathers reported that their spouse was worried about the strain on their children at the EOL. Fathers who reported clearer prognostic communication between wife and physician had lower CES-D and TRIG scores. Conclusions To improve EOL care for seriously ill patients and their families, we must understand the concerns of parents with dependent children. These data underscore the importance of parenting-related worries in this population and the need for additional clinical and research programs devoted to addressing these issues. PMID:26685117

    In an attempt to attract a wider diversity of professionals to the 10th International Gastric Cancer Association Congress (IGCC) held in June 2013, the Scientific Committee of the conference organized a number of pre-congress Web Round Tables to discuss cutting-edge topics relating to gastric cancer treatment. Twenty Web Round Tables, each coordinated by a different chairman, were proposed on the IGCC Website 1 year before the congress. Each chairman identified a number of studies related to the theme of his/her Round Table and invited corresponding authors to send an update of their conclusions in light of their subsequent experience, which would then form the basis of discussion of the Web Round Tables. The chairmen posted several questions regarding these updates on the web and opened a forum for a period of 1-2 months. The forum was free and specifically intended for congress participants. Fifty-one (9.9 %) of the 516 authors contacted took part in the initiative. Two hundred fifty participants from 21 countries joined the forum discussion and posted 671 comments. The Web Round Tables were viewed 15,810 times while the forum was open. Overall, the Web Round Tables aroused considerable interest, especially among young professionals working in the area of gastric cancer who had the opportunity to contact and interact with experts in what often turned out to be an interesting and lively exchange of views. All the discussions are now freely available for consultation on the IGCC website. The Web Round Table experience was presented, with great success, during the conference at special afternoon sessions.

    Immigrant families with children with developmental disabilities must be served using culturally sensitive approaches to service and research to maximize treatment benefits. In an effort to better understand cultural issues relevant to the provision of parenting programs for immigrant Mexican mothers of children with developmental disabilities, we conducted sustained focus groups through which we could learn more about our participants and thereby improve services. This paper reports on the challenges and lessons learned from these groups. We characterize the key lessons as (a) recruitment and retention is more than agreement to participate; (b) confidentiality is not just a word but an activity; (c) the complicated nature of language; (d) cultural norms shape the group process; (e) appreciating the value of taking time; and (f) gender issues and group interaction. Service providers and researchers who work with Mexican families may benefit from our experiences as they promote and develop programs and projects in the developmental disabilities field.

    This article concerns animal experimentation and official Mexican norm Nom 0062-Zoo-1999 entitled Technical specifications for the production, care and use of laboratory animals. The history of animal experimentation is briefly resumed. During the nineteenth century, doubts arose as to the right to expose animals to experimental procedures that frequently cause pain and suffering. The first law which protected animals against cruelty was passed in Great Britain in 1876; subsequently, other nations approved similar legislation. During the second part of the twentieth century, opposition to animal experimentation grew. Other groups, mainly scientists and pharmaceutical concerns, defended the right to use animals in research. New knowledge concerning the neurophysiology, cognitive capacity, and the animal faculty to experience pain is briefly mentioned. Guidelines on care and use of animals used in research published in several countries are listed. Finally, the recently published Mexican legislation (Norm) referring to production, care and use of laboratory animals is discussed and its benefits are stressed.

    Chronic lymphocytic leukemia (CLL) is the most frequent leukemia in adults living in Western countries, and accounts for approximately 30% of adult leukemias. In a 15-year period in a single institution, we identified 19 patients with CLL in a group of 211 adults with leukemia (9% of adult leukemias). Of these 19 CLL patients, 8 had a Caucasian phenotype, 4 were born outside the country, and only 11 were Mexican mestizos. On the other hand, in a multicenter experience involving 1968 Mexican adults with leukemia, CLL represented 6.6% of the cases, a figure significantly lower than that reported in Caucasians (P mestizos, and this low prevalence may stem from the genetic origin of this racial group. The data also suggest a genetic predisposition of Caucasians to suffer from this disease.

    Children commonly observe and pitch in to ongoing activities in Indigenous communities of Mexico, according to ethnographic research. The present study examines the generality of this approach to learning by comparing its use among Mexican immigrants of two cultural backgrounds in the United States. Results showed more sustained attention to (and learning from) instruction directed to another person by 22 U.S. Mexican-heritage 6- to 11-year-old children whose families likely have experience with Indigenous practices (and limited involvement in Western schooling), compared with 16 U.S. Mexican-heritage children whose families have extensive involvement in Western schooling (and related practices).

    The application of modern molecular tests such as next-generation sequencing (NGS) to human malignancies has led to better understanding of tumor biology and the design of targeted molecular therapies. In the research setting, important genomic alterations in tumors have been discovered with potential therapeutic implications but data regarding the impact of this technology in a real world oncology practice is limited. As a result, we decided to review the results of NGS in 144 advanced-stage cancer patients referred to the oncology practices of Lifespan-affiliated centers in Rhode Island. Most cancers revealed genomic alterations in genes commonly mutated in cancer. However, several unexpected genomic alterations were discovered in certain cancers with potential therapeutic intervention. Most cancers contained "actionable" genomic alterations despite being of advanced stage. Our experience demonstrates that application of NGS in the clinical setting contributes both to increasing the therapeutic armamentarium as well as our understanding of tumor biology.

    Full Text Available Introduction. At the Department of Minimally Invasive Upper Digestive Surgery of the Hospital for Digestive Surgery in Belgrade, hybrid minimally invasive esophagectomy (hMIE has been a standard of care for patients with resectable esophageal cancer since 2009. As a next and final step in the change management, from January 2015 we utilized total minimally invasive esophagectomy (tMIE as a standard of care. Objective. The aim of the study was to report initial experiences in hMIE (laparoscopic approach for cancer and analyze surgical technique, major morbidity and 30-day mortality. Methods. A retrospective cohort study included 44 patients who underwent elective hMIE for esophageal cancer at the Department for Minimally Invasive Upper Digestive Surgery, Hospital for Digestive Surgery, Clinical Center of Serbia in Belgrade from April 2009 to December 2014. Results. There were 16 (36% middle thoracic esophagus tumors and 28 (64% tumors of distal thoracic esophagus. Mean duration of the operation was 319 minutes (approximately five hours and 20 minutes. The average blood loss was 173.6 ml. A total of 12 (27% of patients had postoperative complications and mean intensive care unit stay was 2.8 days. Mean hospital stay after surgery was 16 days. The average number of harvested lymph nodes during surgery was 31.9. The overall 30-day mortality rate within 30 days after surgery was 2%. Conclusion. As long as MIE is an oncological equivalent to open esophagectomy (OE, better relation between cost savings and potentially increased effectiveness will make MIE the preferred approach in high-volume esophageal centers that are experienced in minimally invasive procedures.

    Full Text Available Photodynamic therapy (PDT is a treatment modality used in the management of solid tumor malignancies that employs the use of a photosensitizing agent, a light source and oxygen in order to illicit a direct cytotoxic effect. Its use in gynecologic malignancies is somewhat novel and has been used for palliative and curative intent. At the Roswell Park Cancer Institute, the use of PDT in the management of gynecologic cancers began in the mid 1980s and since that time 35 patients have received PDT as a treatment for recurrent or metastatic cutaneous and vulvar, vaginal, anal, and cervical recurrences. In our experience, 85% patients with metastatic cutaneous lesions had a complete response. Twenty-seven percent of patients with metastatic vaginal, cervical or anal recurrences had a complete response to therapy with a median response time of 28 months. Side effects from the treatment included moderate to severe burning sensation, pain and edema at the treatment site requiring narcotic pain medication for symptom management in patients who underwent treatment to cutaneous lesions as well as lower genital tract recurrences. PDT should be considered an option in patients who are too frail to undergo the standard of care or decline the standard of care in lieu of a less invasive treatment modality.

    Full Text Available For several decades any diagnosis of prostate cancer (PCa has been considered an absolute contraindication to the use of testosterone (T therapy in men. Yet this prohibition against T therapy has undergone recent re-examination with refinement of our understanding of the biology of androgens and PCa, and increased appreciation of the benefits of T therapy. A reassuringly low rate of negative outcomes has been reported with T therapy after radical prostatectomy (RP, radiation treatments, and in men on active surveillance. Although the number of these published reports are few and the total number of treated men is low, these experiences do provide a basis for consideration of T therapy in selected men with PCa. For clinicians considering offering this treatment, we recommend first selecting patients with low grade cancers and undetectable prostate-specific antigen following RP. Further research is required to define the safety of T therapy in men with PCa. However, many patients symptomatic from T deficiency are willing to accept the potential risk of PCa progression or recurrence in return for the opportunity to live a fuller and happier life with T therapy.

    Full Text Available The purpose of this study was to explore the emotional and psychosocial experiences of Ghanaian women living with advanced breast cancer in the Kumasi metropolis. The study employed a qualitative exploratory descriptive design. Purposive sampling approach was used and data was saturated with 10 participants aged between 32 and 65 years. All interviews were audio-taped and transcribed. Data was analyzed concurrently based on the techniques of content analysis. Anonymity and confidentiality were ensured. Women experienced emotional reactions such as sadness, fear, and anxiety. Pain was severe and led to suicidal ideations. Women experienced lost hopes regarding their marriage, parenting, and work. They received support from their families, spouses, colleagues, health professionals, and spiritual leaders. Women coped by accepting the disease and surrendering to God and having the will to live. Five major themes described were emotional reactions, pain, lost hope, support, and coping. It was recommended that health care providers involved in breast cancer management should be trained to enhance effective and holistic care of women and their families. Also, patients with advanced disease should be given effective pain management and a multidisciplinary palliative care team should be instituted to care for the women.

    Full Text Available Abstract Background To report about early clinical experience in radiation treatment of head and neck cancer of different sites and histology by volumetric modulated arcs with the RapidArc technology. Methods During 2009, 45 patients were treated at Istituto Clinico Humanitas with RapidArc (28 males and 17 females, median age 65 years. Of these, 78% received concomitant chemotherapy. Thirty-six patients were treated as exclusive curative intent (group A, three as postoperative curative intent (group B and six with sinonasal tumours (group C. Dose prescription was at Planning Target Volumes (PTV with simultaneous integrated boost: 54.45Gy and 69.96Gy in 33 fractions (group A; 54.45Gy and 66Gy in 33 fractions (group B and 55Gy in 25 fractions (group C. Results Concerning planning optimization strategies and constraints, as per PTV coverage, for all groups, D98% > 95% and V95% > 99%. As regards organs at risk, all planning objectives were respected, and this was correlated with observed acute toxicity rates. Only 28% of patients experienced G3 mucositis, 14% G3 dermitis 44% had G2 dysphagia. Nobody required feeding tubes to be placed during treatment. Acute toxicity is also related to chemotherapy. Two patients interrupted the course of radiotherapy because of a quick worsening of general clinical condition. Conclusions These preliminary results stated that volumetric modulated arc therapy in locally advanced head and neck cancers is feasible and effective, with acceptable toxicities.

    The mainstay of curative gastric cancer treatment is open gastric resection with regional lymph node dissection. Minimally invasive surgery is yet to become an established technique with a well defined role. Robotic surgery has by-passed some of the limitations of conventional laparoscopy and has proven both safe and feasible. We present our initial experience with robotic surgery based on 41 gastric cancer patients. We especially wish to underline the advantages of the robotic system when performing the digestive tract anastomoses. We present the techniques of end-to-side eso-jejunoanastomoses (using a circular stapler or manual suture) and side-to-side eso-jejunoanastomoses. In our hands, the results with circular stapled anastomoses were good and we advocate against manual suturing when performing anastomoses in robotic surgery. Moreover, we recommend performing totally intracorporeal anastomoses which have a better post-operative outcome, especially in obese patients. We present three methods of realising the total intracorporeal eso-jejuno-anastomosis with a circular stapler: manual purse-string suture, using the OrVil and the double stapling technique. The eso-jejunoanastomosis is one of the most difficult steps in performing the total gastrectomy, but these techniques allow the surgeon to choose the best option for each case. We consider that surgeons who undertake total gastrectomies must have a special training in performing these anastomoses.

    2014-07-01

    There is limited research directly examining the process of how Mexican American college students cope with unique experiences of racial discrimination. The present study used a multiple mediation model to collectively examine the indirect effects of engagement (i.e., problem solving, cognitive restructuring, expression of emotion, and social support) and disengagement (i.e., social withdrawal, self-criticism, problem avoidance, and wishful thinking) coping strategies on the relationship between perceived racial discrimination and subjective well-being of 302 Mexican American college students. Results suggested that perceived racial discrimination was negatively correlated with subjective well-being. Moreover, of the engagement coping strategies examined, only problem solving had a significant mediating effect that was associated with elevations in subjective well-being. Specifically, perceptions of racial discrimination were positively related to problem solving, which, in turn, was positively related to subjective well-being. Of the disengagement coping strategies examined, self-criticism, wishful thinking, and social withdrawal had a significant mediating effect that was negatively associated with subjective well-being. Specifically, perceptions of racial discrimination were positively related to self-criticism, wishful thinking, and social withdrawal, which, in turn, were negatively related to subjective well-being. Ultimately, these findings highlight the indirect and complex ways in which multiple coping strategies are used to effectively, and sometimes not effectively, deal with racism experienced by Mexican Americans college students.

    This study examined whether Mexican-American parents' experiences with discrimination are related to adolescent psychological adjustment over time. The extent to which associations between parent discrimination and adolescent adjustment vary as a function of parents' ethnic socialization of their children was also examined. Participants included 344 high school students from Mexican or Mexican-American backgrounds (primarily second generation; ages 14-16 at Wave 1) and their primary caregivers who completed surveys in a 2-year longitudinal study. Results revealed that parent discrimination predicted internalizing symptoms and self-esteem among adolescents 1 year later. Additionally, adolescents were more likely to report low self-esteem in relation to parents' increased experiences of discrimination when parents conveyed ethnic socialization messages to them.

    This article explores the experiences of older patients with cancer in phase 1 clinical trials. Conducting a case series of face-to-face, in-depth, open-ended interviews and using qualitative methods of analysis, we find that the psychosocial process of social comparison is relevant for understanding older adults' phase 1 clinical trial participation. Social comparison influences decisions to enroll in a phase 1 clinical trial, shapes perceptions of supportive care needs, and encourages the utilization of hope. Additional research should develop strategies for addressing supportive care needs among this patient cohort whose use of social comparison can inhibit articulation of pain, suffering, and symptom burden as well as use of informal support systems.

    Full Text Available This is a study with the objective to know the experiences of the family caregiver of a person with intestinal ostomy due to colorectal cancer. A qualitative research, grounded on the humanization referential, made in 2013, through serialized semi-structured interviews and inductive analysis. It was approved by the Ethics and Research Committee under legal opinion no. 237,771. Seven family caregivers participated in this study in a county of southern Minas Gerais state, Brazil. Three categories emerged from the data: Relation with the disease and its treatments; Impact facing treatment and rehabilitation and Nets of support. The representation of the disease associated to finitude is reaffirmed. In order to lessen anguish and suffering, the family caregivers search support, mainly in spirituality. The impact resulting from the illness and the rehabilitation process imposes a new order to the caregivers, with personal and social renouncing, which provides a closer and more dedicated relation with the patient.

    2012-01-01

    In this study, the authors examined the experiences of grandparents who have had, or have, a grandchild with childhood cancer. Sixteen grandparents were interviewed using unstructured interviews, and the data were analyzed according to a hermeneutic-phenomenological tradition, as guided by the philosophical hermeneutics of Hans-Georg Gadamer. In Part 1 of this report, interpretive findings around worry, burden, silence, the nature of having one's universe shaken, of having lives put on hold, and a sense of helplessness were addressed. In Part 2, the authors discuss interpretations related to the notions of support, burden, protection, energy, standing by, buffering, financial shouldering, and relationship. The study concludes with implications that the grandparents in the study bring to pediatric nurses in their practices with families in pediatric oncology.

    This study examined whether Mexican (n = 53), Mexican American (n = 50), and European American (n = 51) children differed in their reporting of anxiety symptoms and whether parental influence and specific cognitive schemas associated with Mexican culture were related to differences in anxiety reporting. As expected, Mexican and Mexican American children reported significantly more physiological and worry symptoms than the European American children. Mexican and Mexican American children endorsed collectivism as a cultural value more strongly than European American children, and the Mexican children evidenced greatest use of social strategies reflecting simpatia. In family discussions of ambiguous, potentially anxiety-arousing situations, Mexican and Mexican American parents verbalized a greater percentage of somatic interpretations than the European American parents. Results indicate potential linkages between cultural values, socialization practices, and anxiety reporting.

    2003-12-01

    As family caregivers assume more prominent roles in the provision of home care to persons with serious illness, investigators must test the effectiveness of novel interventions to facilitate family caring for cancer patients. This article is based on results derived from a larger study carried out in Canada that was designed to compare 98 advanced cancer patient and family caregiver perceptions of 32 patient symptom experiences as captured by the Memorial Symptom Assessment Scale. We examined two main questions: (1) whether "natural" family caregivers' perceptions of patient lack of energy and worrying are more closely related to a self- or patient-oriented viewpoint and (2) whether induced "imagine-patient" perspective-taking can assist caregivers to achieve better perceptual accuracy. The caregiver's natural responses to neutral instructions that neither encouraged nor discouraged perspective-taking served as the baseline comparison with three other instructional sets, in which caregivers were prompted to: (1) provide a self-report on their own symptom experiences, (2) imagine how they would feel in the patient's situation (imagine-self), or (3) imagine how the patient would respond to his or her symptom situation (imagine-patient). Findings suggested that the family caregivers' natural judgments correspond most closely to what they do under an imagine-patient set than to what they do under any other set. Findings with respect to accuracy indicated that instructions to imagine the patient's perspective helped to prompt adjustments down from a self-oriented viewpoint, although definitive conclusions were precluded by difficulties with order effects.

    2016-01-01

    Background Single-port video-assisted thoracic surgery (SPVATS) emerged several years ago as a new, minimally invasive surgery for diseases in the field of respiratory surgery, and is increasingly becoming a subject of interest for some thoracic surgeons in Europe and Asia. However, the adoption rate of this procedure in the United States and Japan remains low. We herein reviewed our experience of SPVATS for early lung cancer in our center, and evaluated the safety and minimal invasiveness of this technique. Methods We retrospectively analyzed patients who had undergone SPVATS for pathological stage I lung cancer in Nippon Medical School Chiba Hokusoh Hospital between September 2012 and October 2015. In SPVATS, an approximately 4-cm incision was made at the 4th or 5th intercostal space between the anterior and posterior axillary lines. A rib spreader was not used at the incision site, and surgical manipulation was performed very carefully in order to avoid contact between surgical instruments and the intercostal nerves. The same surgeon performed surgery on all patients, and analyzed laboratory data before and after surgery. Results Eighty-four patients underwent anatomical lung resection for postoperative pathological stage I lung cancer. The mean wound length was 4.2 cm. Eighty-four patients underwent lobectomy and segmentectomy, respectively. The mean preoperative forced expiratory volume in 1 second (FEV1%) was 1.85%±0.36%. Our patients consisted of 49 men (58.3%) and 35 women (41.7%), with 64, 18, 1, and 1 having adenocarcinoma, squamous cell carcinoma, adenosquamous carcinoma, and small-cell lung cancer, respectively. The mean operative time was 175±21 min, operative blood loss 92±18 mL, and duration of drain placement 1.9±0.6 days. The duration of the postoperative hospital stay was 7.1±1.7 days, numeric rating scale (NRS) 1 week after surgery 2.8±0.6, and occurrence rate of allodynia 1 month after surgery 10.7%. No patient developed serious

    2013-02-01

    Full Text Available Abstract Background The care of patients suffering from cancer and especially those facing the death trajectory appears to be complex and demanding not only for student nurses but for professional nurses as well. The educational models often used in nursing require students to face challenging care scenarios, sometimes with minimal or no supervision and guidance. These “worst case scenarios” can be traumatic experiences that can leave the student hopeless and disappointed of themselves and in many cases can “scar” their subsequent professional career. The literature demonstrates that this can be the result of the students’ ill-preparation to care for cancer patients and deal with death and dying. The purpose of this study was to interpret the students’ experiences of coming face-to-face with cancer care during their clinical placements. Methods This is a hermeneutic phenomenological study influenced by the ideas of the French Philosopher Paul Ricoeur. Based on this philosophical enquiry the interpretation process included three stages: 1 naïve reading, 2 structural analysis and 3 comprehensive understanding. Data were collected through reflective/narrative diaries from the 4th grade undergraduate (pre-registration nursing students practicing at oncology, hematology, pediatric oncology departments and hospices. Diaries of twelve students met the inclusion criteria and were included in the interpretation process. The study took place during January and May 2011. Results The interpretation yielded the following themes: a Being part of the center’s life, b Being sympathetic, c Being confronted by others, d Being self-reflective, e Being trapped in the system, f Being caring towards the family and g Being better in clinical practice. Conclusions The students emphasized the need for appropriate preparation both at a theoretical and at a clinical level, as to better confront situations involving death and dying as well as learning

    In order to take advantage of the solar radiation as an alternate energy source it is necessary to evaluate the spatial and temporal availability. The Mexican National Meterological Service (SMN) has a network with 136 meteorological stations, each coupled with a pyronometer for measuring the global solar radiation. Some of these stations had not been calibrated in several years. The Mexican Department of Energy (SENER) in order to count on a reliable evaluation of the solar resource funded this project to calibrate the SMN pyrometer network and validate the data. The calibration of the 136 pyronometers by the intercomparison method recommended by the World Meterological Organization (WMO) requires lengthy observations and specific environmental conditions such as clear skies and a stable atmosphere, circumstances that determine the site and season of the calibration. The Solar Radiation Section of the Instituto de Geofísica of the Universidad Nacional Autónoma de México is a Regional Center of the WMO and is certified to carry out the calibration procedures and emit certificates. We are responsible for the recalibration of the pyronometer network of the SMN. A continuous emission solar simulator with exposed areas with 30cm diameters was acquired to reduce the calibration time and not depend on atmospheric conditions. We present the results of the calibration of 10 thermopile pyronometers and one photovoltaic cell by the intercomparison method with more than 10000 observations each and those obtained with the solar simulator.

    Full Text Available Pazopanib is an oral angiogenesis inhibitor, currently approved for treatment of metastatic renal cell carcinoma (mRCC and soft tissue sarcoma. The present study analyzed the outcomes of pazopanib in first-line treatment of mRCC, in a single Italian cancer center. In the light of the retrospective, observational nature and the unselected population, our experience can be defined a real-world study. The medical records of 38 mRCC patients treated with front-line pazopanib were retrospectively reviewed and analyzed. The progression free survival (PFS and the overall survival (OS were the primary endpoints, while secondary objectives included Objective Response Rate (ORR, Disease Control Rate (DCR, and treatment tolerability. Pazopanib achieved a median PFS (mPFS of 12.7 months (95% CI, 6.9-18.5 months. The median OS (mOS was 26.2 months (95% CI, 12.6-39.9 months; the observed ORR and DCR were 30.3% and 72.7%, respectively, with a median duration of response of 11 weeks. mPFS appeared not to be influenced by number of co-morbidities (3, gender, Fuhrman grade and age. Conversely, the ORR and the DCR positively affect the mPFS (HR=0.05 [95% CI, 0.05-055], p=0.01; HR=0.10 [95% CI, 0.02-0.43], p=0.002 respectively. A worse outcome was associated with a lower mPFS in patients with liver metastases (p= 0.2 and with a high tumor burden (number of metastatic sites 6 (p= 0.08. Worst OS was observed in patients age >70 years old (HR=6.91 [95% CI, 1.49-31.91], p=0.01. The treatment was well tolerated: no grade 4 adverse events, nor discontinuation due to toxicities was reported. Grade 3 hypertension affected positively the OS reaching the statistical significance (HR=0.22 [95% CI, 0.05-0.8], p=0.03 and thyroid dysfunction (hypo and hyperthyroidism seems to correlate with better outcome in terms of a longer mPFS (HR=0.12 [95% CI, 0.02-0.78], p=0.02. Our results are consistent with those reported in prospective phase III trials and the published retrospective

    Biographical accounts of illness offer useful insights into the social and adaptive processes of living with chronic illness. Yet there are concerns that the underlying theoretical assumptions of a reflexive self seeking to maintain meaning may not reflect the lived experience of individuals. A narrative emphasis may neglect the importance of emotional/felt experiences; while an analytical focus on disruptive processes may not adequately reflect the totality of actual events. In this study, we explored how well biographical theory supports understanding of individual lived experience. Narratives from 19 individuals identified from General Practice lists with a terminal diagnosis of cancer were analysed using the holistic-form approach described by Lieblich. Participants described an ongoing process of living their life, 'managing' disruptive events and maintaining an overall sense of well-being (narrative form = biographical flow). For a minority, continuity was lost when people's capacity to continue living their everyday lives was overwhelmed (narrative form = fracture). The identified emphasis was on individual creative capacity in the face of terminal illness, highlighting the importance of embodied experience in understanding outcome and need. Maintaining continuity was draining: exhaustion precipitated fracture and thus need for external help to restore continuity. By focusing on feelings associated with overall narrative form, rather than individual disruptive events, we highlight the context in which disruptive events are experienced, and individual perceptions of their relative importance. We conclude that combining narrative and emotion offers new insights into the value of understanding of biographical accounts of illness in the context of individual creative capacity. We discuss the possibilities for new approaches to clinical assessment and management of need.

  12. Mexican and Mexican-American children's funds of knowledge as interventions into deficit thinking: opportunities for praxis in science education

    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.

    The prevalence of overweight is higher for Hispanic children of immigrants than children of natives. This does not fit the pattern of the epidemiological paradox, the widely supported finding that immigrants tend to be healthier than their U.S.-born peers, and it suggests that exposure to the U.S. increases immigrant children's risk of overweight. This study's primary contribution is to better assess how exposure to the U.S. environment affects childhood overweight among a homogamous ethnic group, Mexican-Americans. We do so by using an innovative binational study design to compare the weight of Mexican-American children of immigrants, Mexican-American children of natives, and Mexican children in Mexico with different propensities of having immigrant parents. Cross-sectional data are derived from a pooled sample of 9982 6-19 year old children living in either Mexico or the United States in the early 2000s. Mexican-resident children with a very high propensity to have immigrant parents have significantly lower percentile BMIs and lower odds of overweight than Mexican children with lower propensities of emigration and U.S.-resident Mexican-American children. This suggests that selection into immigration streams does not account for the high prevalence of overweight among children of Mexican immigrants. Rather, U.S. exposure significantly raises children of Mexican immigrants' risk of being overweight. Moreover, second generation children have the highest percentile BMIs and greatest odds of overweight of all comparison groups, including children of natives. This suggests that they experience risks above and beyond the effects of exposure to American society.

  14. Effects of High Temperature and Water Stress on Seed Germination of the Invasive Species Mexican Sunflower.

    Mexican sunflower is native to Mexico and Central America and was introduced into China early last century. Now it has widely naturalized and is exhibiting increasing invasiveness in South China. As this species often dominates bare ground, a habitat characterized by extreme fluctuation in temperature and water, it is reasonable to hypothesize that it has special adaptations to high temperature and water stress. Using laboratory experiments to simulate these stresses, this study investigated the response of Mexican sunflower seed germination to temperature and water stress, and compared these responses with those previously reported for another invasive, bamboo piper, which is confined to relatively cool and moist habitats in Xishuangbanna. As expected, Mexican sunflower seeds exhibited higher tolerance to these stresses than bamboo piper. Germination of Mexican sunflower seeds was highest at 15-30°C, but significant numbers of seeds germinated and formed seedlings at 10°C and 35°C, at which no bamboo piper seeds formed seedlings, indicating a wider temperature range for germination than the latter. Roughly half the seeds survived 240 h continuous heat treatment and up to 15 h daily periodical heat treatment at 40°C, while bamboo piper seeds were mostly killed by these treatments. About 20% of Mexican sunflower but no bamboo piper seeds germinated after heat treatment for 30 min at 80°C. Germination was completely inhibited in bamboo piper seeds at -0.6 mPa, while 20-60% of Mexican sunflower seeds germinated depending on PEG or NaCl as osmoticum. This higher tolerance in Mexican sunflower seeds accords with its stronger invasiveness in this area. This comparison between two plant invaders demonstrates that invasiveness is not an all-or-nothing situation, and that adaptation to local habitats is a critical determinant of successful invasiveness for an alien plant.

    Purpose Survivorship care plans (SCP) are recommended for all cancer patients and could be especially useful to survivors 65 years and over (“older”). This study examined receipt of SCPs among older breast cancer survivors and whether SCPs were associated with improved patient-reported outcomes. Methods Three hundred and twenty-eight older women diagnosed with invasive, nonmetastatic breast cancer between 2007–2011 were recruited from 78 cooperative-group sites. Participants completed telephone interviews at baseline and 1-year posttreatment. Regression analyses examined SCP receipt (yes/no) and functioning (EORTC-QLQ-C30), cancer worry, and experiences of survivorship care (care coordination, knowledge). Results Only 35 % of women received SCPs. For each 1-year increase in age, there was a 5 % lower odds of receiving an SCP (odds ratio (OR)=0.94, 95 % confidence interval (CI) 0.91–0.98, p=0.007). Besides age, no other factor predicted SCPs. SCP receipt was associated with greater knowledge and understanding of requisite follow-up care (p<0.05); however, functioning was not significantly different among those with vs. without SCPs. Conclusions Receipt of care plans was limited. SCPs improved understanding of breast cancer follow-up care among older survivors, but did not impact functioning one year post-treatment. Implications for Cancer Survivors To impact functioning and salient needs of the growing cohort of older survivors, survivorship care plans likely should be tailored to geriatric-specific issues. To improve functioning, SCP content should expand to include exercise, nutrition, polypharmacy, social support and management of symptom burden from cancer, and other comorbid conditions. To improve follow-up care for cancer survivors, SCPs should delineate shared care roles between oncology and primary care in managing recurrence surveillance, screening, and cancer sequelae.

    Stakeholder input is a critical component of comparative effectiveness research. To ensure that the research activities of the Developing Evidence to Inform Decisions about Effectiveness (DEcIDE) Network, supported by the Agency for Healthcare Research and Quality, translate into the greatest impact for everyday practice and policy-making in cancer, we were tasked with soliciting stakeholder input regarding priority areas in cancer-related comparative effectiveness research for the DEcIDE Cancer Consortium. Given the increasing emphasis on stakeholder engagement in research, many investigators are facing a similar task, yet there is limited literature to guide such efforts, particularly in cancer care. To help fill this gap, we present our approach to operationalizing stakeholder engagement and discuss it in the context of other recent developments in the area. We describe challenges encountered in convening stakeholders from multiple vantage points to prioritize topics and strategies used to mitigate these barriers. We offer several recommendations regarding how to best solicit stakeholder input to inform comparative effectiveness research in cancer care. These recommendations can inform other initiatives currently facing the challenges of engaging stakeholders in priority setting for cancer.

    Seventy percent of Mexican households experience some level of food insecurity (FI). Studies have shown positive associations between FI and poor dietary quality. As far as it is known, this is the first time the Healthy Eating Index (HEI-2010) has been used to assess dietary quality of children and adolescents in Mexico, and to examine if FI is related to it. The objective of this research is to assess dietary quality and its association with FI among Mexican children and adolescents from a nationally representative cross-sectional sample. We analyzed data from 4635 2-19-year-old Mexican children and adolescents participating in the Mexican National Health and Nutrition Survey (Ensanut 2012). FI was measured using the Latin American and Caribbean Household Food Security Scale (ELCSA) and dietary quality with the HEI-2010. We examined the association between FI and dietary quality using multivariate linear regressions. Dietary quality was worst as FI became more severe among children and adolescents compared with their counterparts living in households with food security. Specifically, FI had a negative association with fruits, vegetables, and protein foods, and a positive association with refined grains consumption. Dairy intake was negatively associated with FI among older children and adolescents. Added sugars were not associated with FI, but intake was excessive across the population at 15% of total daily energy intake. Decreasing FI may help improve dietary quality of Mexican children and adolescents.

    Objective: to report an experiment involving the introduction of a protocol utilizing commercially available three-dimensional 1H magnetic resonance spectroscopy imaging (3D 1H MRSI) method in patients diagnosed with prostatic tumors under suspicion of neoplasm. Materials and methods: forty-one patients in the age range between 51 and 80 years (mean, 67 years) were prospectively evaluated. The patients were divided into two groups: patients with one or more biopsies negative for cancer and high specific-prostatic antigen levels (group A), and patients with cancer confirmed by biopsy (group B). The determination of the target area (group A) or the known cancer extent (group B) was based on magnetic resonance imaging and MRSI studies. Results: the specificity of MRSI in the diagnosis of prostate cancer was lower than the specificity reported in the literature (about 47%). On the other hand, for tumor staging, it corresponded to the specificity reported in the literature. Conclusion: the introduction and standardization of 3D 1H MRSI has allowed the obtention of a presumable diagnosis of prostate cancer, by a combined analysis of magnetic resonance imaging and metabolic data from 3D 1H MRSI.

    1999-04-01

    The diaspores of the 50 most important maize field weed species (agrestals) in a traditional maize-growing area of south-central Mexico (region of Puebla and Tlaxcala) were analyzed for morphological adaptations to long-distance dispersal. Adaptations to wind-dispersal were absent and to endozoochory were minimal. Most species had no visible adaptations and are presumably transported with mud. However, about one-quarter of the taxa, particularly the tall and dominant ones, relied at least partially on burrs with hooks or awns. The possible vectors for these exo- or epizoochorous species are discussed: the most likely regular dispersers are humans (epianthropochory). Interviews with farmers confirm this conclusion. Using humans as vectors allows the plant to transport relatively large seeds to favorable habitats (directed dispersal). The importance of this relatively rare dispersal adaptation in Mexican maize field weeds leads to questions on the origin and evolution of these agrestals.

    Pazopanib is an oral angiogenesis inhibitor, currently approved for treatment of metastatic renal cell carcinoma (mRCC) and soft tissue sarcoma. The present study analyzed the outcomes of pazopanib in first-line treatment of mRCC, in a single Italian cancer center. In the light of the retrospective, observational nature and the unselected population, our experience can be defined a “real-world” study. The medical records of 38 mRCC patients treated with front-line pazopanib were retrospectively reviewed and analyzed. The progression free survival (PFS) and the overall survival (OS) were the primary endpoints, while secondary objectives included objective response rate (ORR), disease control rate (DCR), and treatment tolerability. Pazopanib achieved a median PFS (mPFS) of 12.7 months (95% CI, 6.9–18.5 months). The median OS (mOS) was 26.2 months (95% CI, 12.6–39.9 months); the observed ORR and DCR were 30.3 and 72.7%, respectively, with a median duration of response of 11 weeks. mPFS appeared not to be influenced by number of co-morbidities (< 3 vs. ≥3), gender, Fuhrman grade and age. Conversely, the ORR and the DCR positively affect the mPFS (HR = 0.05 [95% CI, 0.05–0.55], p = 0.01; HR = 0.10 [95% CI, 0.02–0.43], p = 0.002, respectively). A worse outcome was associated with a lower mPFS in patients with liver metastases (p = 0.2) and with a high tumor burden (number of metastatic sites < 6 vs. ≥6) (p = 0.08). Worst OS was observed in patients aged ≥70 years old (HR = 6.91 [95% CI, 1.49–31.91], p = 0.01). The treatment was well-tolerated: no grade 4 adverse events, nor discontinuation due to toxicities was reported. Grade 3 hypertension affected positively the OS reaching the statistical significance (HR = 0.22 [95% CI, 0.05–0.8], p = 0.03). Thyroid dysfunction (hypo and hyperthyroidism) seems to correlate with better outcome in terms of a longer mPFS (HR = 0.12 [95% CI, 0.02–0.78], p = 0.02). Our results are consistent with those reported in

  20. Concordance of Chronic Conditions in Older Mexican American Couples

    2005-07-01

    Full Text Available Introduction There is substantial evidence that marriage is beneficial to health, but evidence on whether the health status of one spouse is similar, or concordant, with the other spouse is limited. This study assessed whether a chronic condition of one spouse is a risk factor for the same chronic condition in the other spouse. Methods The study used baseline data from the Hispanic Established Populations for the Epidemiologic Studies of the Elderly on 553 couples (1106 individuals who are representative of approximately 500,000 older (≥65 years Mexican Americans living in the southwestern United States. Logistic regression was used to predict six chronic conditions among couples: heart condition, stroke, hypertension, diabetes, arthritis, and cancer. Analyses were adjusted for age, education, U.S. nativity, blood pressure, body mass index, smoking, and alcohol consumption. Results The wife’s history of hypertension, diabetes, arthritis, and cancer was associated with higher odds that the husband would have these conditions. A history of hypertension, arthritis, and cancer in the husband was associated with higher odds that the wife would have these conditions. Conclusion These results provide preliminary evidence that chronic conditions in one spouse are associated with an increased risk of developing like conditions in the other spouse among older Mexican American couples. We propose that the reciprocal influence that marital partners have on each other may be caused by shared living arrangements and shared health risks. Health promotion activities should target family systems. In particular, health providers should gather health histories not only from patients and their genetic family members but also from spouses.

    From May 1991 through September 1992, a total of 17 previously untreated patients with invasive uterine cervix cancer and with intact uterus were treated with mid-dose rate intracavitary therapy administered with a Selectron. Early primary tumor responses for all patients were complete. No acute or subacute radiation injury was observed except one patient with aplastic anemia who developed rectal ulcer. Two patients of Stage IIIb died from tumor because of local, paraaortic lymph node and distant metastases. Our early experience concluded that Selectron MDR can be used for cervix cancer patients as safely and effectively as our previously used high-dose rate machine. (author).

    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.

  6. Patients' & healthcare professionals' values regarding true- & false-positive diagnosis when colorectal cancer screening by CT colonography: discrete choice experiment.

    Directory of Open Access Journals (Sweden)

    Darren Boone

    Full Text Available PURPOSE: To establish the relative weighting given by patients and healthcare professionals to gains in diagnostic sensitivity versus loss of specificity when using CT colonography (CTC for colorectal cancer screening. MATERIALS AND METHODS: Following ethical approval and informed consent, 75 patients and 50 healthcare professionals undertook a discrete choice experiment in which they chose between "standard" CTC and "enhanced" CTC that raised diagnostic sensitivity 10% for either cancer or polyps in exchange for varying levels of specificity. We established the relative increase in false-positive diagnoses participants traded for an increase in true-positive diagnoses. RESULTS: Data from 122 participants were analysed. There were 30 (25% non-traders for the cancer scenario and 20 (16% for the polyp scenario. For cancer, the 10% gain in sensitivity was traded up to a median 45% (IQR 25 to >85 drop in specificity, equating to 2250 (IQR 1250 to >4250 additional false-positives per additional true-positive cancer, at 0.2% prevalence. For polyps, the figure was 15% (IQR 7.5 to 55, equating to 6 (IQR 3 to 22 additional false-positives per additional true-positive polyp, at 25% prevalence. Tipping points were significantly higher for patients than professionals for both cancer (85 vs 25, p<0.001 and polyps (55 vs 15, p<0.001. Patients were willing to pay significantly more for increased sensitivity for cancer (p = 0.021. CONCLUSION: When screening for colorectal cancer, patients and professionals believe gains in true-positive diagnoses are worth much more than the negative consequences of a corresponding rise in false-positives. Evaluation of screening tests should account for this.

    Full Text Available Purpose. We sought to evaluate our experience using yttrium-90 (90Y resin microsphere hepatic radioembolization as salvage therapy for liver-dominant metastatic colorectal cancer (mCRC. Methods. A retrospective review of consecutive patients with unresectable mCRC who were treated with 90Y after failing first and second line systemic chemotherapy. Demographics, treatment dose, biochemical and radiographic response, toxicities, and survival were examined. Results. Fifty-one patients underwent 90Y treatments of which 69% were male. All patients had previously undergone extensive chemotherapy, 31% had undergone previous liver-directed therapy and 24% had a prior liver resection. Using RECIST criteria, either stable disease or a partial response was seen in 77% of patients. Overall median survival from the time of first 90Y treatment was 10.2 months (95% CI = 7.5–13.0. The absence of extrahepatic disease at the time of treatment with 90Y was associated with an improved survival, median survival of 17.0 months (95% CI = 6.4–27.6, compared to those with extrahepatic disease at the time of treatment with 90Y, 6.7 months (95% CI = 2.7–10.6 Conclusion: 90Y therapy is a safe locoregional therapy that provides an important therapeutic option to patients who have failed first and second line chemotherapy and have adequate liver function and performance status.

    The literature supports a variety of predictor variables to account for the psychological and stress burden experienced by cancer family caregivers. Missing among the predictor variables are the differences by or influence of race/ethnicity. The purpose of this study was to describe the sample, explore differences in outcomes by patient and family caregiver characteristics, and determine if any of the patient and family characteristics, including race/ethnicity, predicted outcomes. Cross-sectional surveys were used to determine sociodemographics, psychological and physical health, and burdens of caregiving among 54 caregivers. The analysis consisted of descriptive methods, including frequencies and t tests, and regression modeling. The sample was 35% African American or Hispanic. African American and Hispanic caregivers were younger than white caregivers and more often women, were rarely the spouse of the patient, and frequently had other dependents, including children and older parents. African American and Hispanic caregivers reported lower incomes and more burden related to finances and employment than did white caregivers. When controlling for sociodemographic factors, there was no difference by race/ethnicity on the outcome measures. The experience of caregiving may supersede race/ethnicity and may be its own cultural entity. Areas of concern include the interrelationship between socioeconomic status and race/ethnicity, the absence of cultural frameworks to direct caregiver research, and the question of cultural relevance of measurement tools.

    This study was conducted to understand patients' experiences of nursing support, to identify gaps between patients' expected needs and the nursing support they received, and to explore reasons for such disparity. A qualitative study with a phenomenological approach was used. A purposive sample of 22 patients with different types of cancer was recruited and interviewed using semistructured guidelines. The data were analyzed using phenomenological analytic methods. Several needs regarding nursing support were expressed, including informational, psychological, clinical, care coordination and communication needs, and there were some unmet or partially-met needs. Reasons for the disparities covered both patient- and nurse-related factors, including patients' lack of awareness regarding how to acquire professional assistance and reluctance to express their needs, and nurses' lack of active communication with patients, inability to provide specific support, and limited resources for coordination. The expectations of nursing support did not always correspond with the actual delivery of nursing care. A tailored intervention is warranted to meet patients' expectations, which might contribute to quality-of-care improvements.

    A child's death caused by cancer generates a deep impact on his/her parents, who can be affected by serious health problems due to an impairment of their lifestyle. Notwithstanding their suffering, some parents manage to overcome it and discover a new meaning for their lives. The goal of this phenomenological study is to understand the lived experiences that help parents to revive after the death of their child due to cancer. The participants were fathers and mothers who believe that they have elaborated their mourning. Their lived experiences were collected in interviews they had previously agreed to give. The question that steered the interview was: "What is the experience you went through that helped you to revive after your child died due to cancer?" Data were analyzed using Streubert's method. Analyzing the interviews of the participants, 3 interweaved essences were detected: transition from surviving to reviving themselves; ascribing a sense and meaning to the life, agony, and death of a child; and helping other parents through one's own experience.

    The Unit of the anatomo-pathology in the "Institut Pasteur de Madagascar" (IPM) examined in the period from September 1992 to June 1996 tissue specimens from 10,275 patients. Tumorous pathology presented 40% of the tissues and half of which were of malign etiology. 64% of the cancer diagnosed were in females. Cervical cancer was most frequently observed (17%), followed by breast cancer (16%). Cancer in the gastro-intestinal tract (15%) was most often located in the colon without sex difference. Stomach cancer occurring predominantly in males presented 25% of the total cases of cancer in the gastro-intestinal tract. Cancer of liver is rarely diagnosed despite the high prevalence of infection with hepatitis B virus. Skin cancer constituted 9% of the malign diagnosis and was mainly found in males. Children under 15 years old presented 7.4% of the total cases of malignancy with the haematopoietic tissues (30%) and the eyes (17%) as the most frequent topic locations. Due to a very low seroprevalence of the HIV in Madagascar, malign tumours associated to AIDS were only seen in a few rare cases. The review of cancer cases in the IPM may not be representative for the cancer epidemiology of Madagascar because of a general very low level of health care coverage, especially in the rural areas. Furthermore, a major part of the specimens originates from easily accessible organsystems, whereas other organs seem less investigated due to lack of appropriate available technique. Therefore, it is not feasible for the moment to establish a cancer register in Madagascar, although the Unit of Pathology in the IPM can offer a valid cancer diagnostical service.

    Prostate cancer is the second most common cancer in men worldwide, accounting for an estimated 1.1 million new cases diagnosed in 2012 (www.globocan.iarc.fr). Currently, there is a lack of specific guidance on supportive care for men with prostate cancer. This article describes a qualitative systematic review and synthesis examining men's experience of and need for supportive care. Seven databases were searched; 20 journal articles were identified and critically appraised. A thematic synthesis was conducted in which descriptive themes were drawn out of the data. These were peer support, support from partner, online support, cancer specialist nurse support, self-care, communication with health professionals, unmet needs (emotional support, information needs, support for treatment-induced side effects of incontinence and erectile dysfunction) and men's suggestions for improved delivery of supportive care. This was followed by the development of overarching analytic themes which were: uncertainty, reframing, and the timing of receiving treatment, information and support. Our results show that the most valued form of support men experienced following diagnosis was one-to-one peer support and support from partners. This review highlights the need for improved access to cancer specialist nurses throughout the care pathway, individually tailored supportive care and psychosexual support for treatment side effects.

  16. Lessons learned from adult clinical experience to inform evaluations of VEGF pathway inhibitors in children with cancer.

    Agents targeting the vascular endothelial growth factor (VEGF) pathway have been studied in adults with cancer for nearly two decades. It is important to assess the lessons learned from this adult experience and to see how these lessons can help inform pediatric development of agents in this class. The benefit achieved from the use of VEGF pathway targeted agents for adult cancers has primarily been to delay for several months disease progression and less commonly time to death for conditions in which cure is not a reasonable expectation. VEGF pathway targeted agents have shown no efficacy when applied in the adjuvant setting. For adults with advanced cancer, prolongation of survival by 2-3 months is considered an important achievement in some settings. However, the primary goal of pediatric oncology clinical research is to identify treatments that allow children to be cured of their cancer and to grow to adulthood without treatment-induced limitations that lower their quality of survival. An important question for the pediatric oncology research community, pharmaceutical companies, and regulatory agencies to address in planning for future clinical trials is whether existing data support a role for VEGF pathway targeted agents in contributing to a therapeutic pathway to cure for children with cancer.

    Using the 2013 HINTS 4 Cycle 2 data representing a general population sample, this study investigates the effects of patients' experiences of uncertainty about prostate cancer during doctor-patient communication, as well as patients' positive assessments of their cancer-related information-seeking experiences, on their fatalistic beliefs regarding cancer and their trust in physicians. Our tests show significant differences in trust in physicians among men who do and do not experience uncertainty about the prostate-specific antigen (PSA) test during doctor-patient communication. The analysis also indicates that individuals with experiences of uncertainty about the PSA test are more likely than those without such experiences of uncertainty to place their trust in doctors. However, no apparent difference or association exists when there are uncertainties relating to treatment choices regarding slow-growing cancer or treatment side effects. Nevertheless, as hypothesized, individuals who positively evaluate their cancer-related information-seeking experiences are less likely to have fatalistic beliefs about cancer. Furthermore, patients' positive assessments are highly predictive of their levels of trust in their physicians. Additionally, tests of interaction effects show that individuals' levels of education moderate the association between uncertainty experiences about the PSA test and both cancer fatalism and trust in physicians. Further implications and limitations of the study are discussed.

    This study explored psychosocial experiences of breast cancer survivors involved in dragon boat programs. Twenty women (M(age) = 58.69, SD = 6.85) were interviewed for 45-60 min about their experiences as members of survivor dragon boat teams. Interviews were analyzed using constructivist grounded theory methods. The dragon boat program facilitated social support from women with common challenges and a shared understanding of survivorship. It also provided opportunities to (re)gain a sense of personal control, develop new identities as athletes, and overcome physical challenges. Together these elements contributed to positive psychological growth and linked to the literature on posttraumatic growth. Future physical activity interventions targeting breast cancer survivors may benefit from developing strategies that share key characteristics of dragon boating.

    Effective screening can reduce colorectal cancer mortality; however, screening uptake is suboptimal. Patients' stories about various health topics are widely available online and in behavioral interventions and are valued by patients. Although these narratives may be promising strategies for promoting cancer screening behavior, scant research has compared the influence of different role models. This study involving content analysis of online stories aimed to (a) describe the content of online experiential narratives about colonoscopy; (b) compare narratives from individuals who had a colonoscopy and either had colon cancer (survivors) or did not have colon cancer (screeners); and (c) generate hypotheses for future studies. The authors identified 90 narratives eligible for analysis from 15 websites. More stories were about White patients, men, and routine (vs. diagnostic) colonoscopy. A higher-than-expected number of narratives reported a family history of colorectal cancer or polyps (20%) and a colorectal cancer diagnosis (47%). Colorectal cancer survivor (vs. screener) stories were longer, mentioned symptoms and diagnostic reasons for getting a colonoscopy more often, and described the colonoscopy procedure or referred to it as easy or painless less often. Future studies should examine the effects of the role model's personal characteristics and the colonoscopy test result on reader's perceptions and intentions to have a colorectal cancer screening.

    Full Text Available Background: According to the literature an increasing number of cancer patients demand for complementary therapies during their disease. Research has demonstrated that some of these therapies are effective and safe as adjunctive treatments in specific symptoms of these patients. Methods: The aims of the paper are to review the main and recent papers of international literature on the effectiveness of complementary medicine (CM therapies on side effects of anti-cancer protocols and improvement in the quality of life of oncological patients, and to describe the integration of evidence-based acupuncture, herbal medicine and homeopathy treatments in Public Cancer Network of the region of Tuscany. Results: After the review of literature and the approval of a Regional Resolution, some CM will be introduced in Cancer Departments in Tuscany to additionally treat cancer-related symptoms and side effects of conventional cancer therapy: acupuncture for nausea and post-chemotherapy and post-surgery vomiting, pain, hot flashes of iatrogenic menopause, xerostomia; homeopathy for hot flashes of iatrogenic menopause and the side effects of radiotherapy; herbal medicine for cancer-related fatigue, nausea and vomiting, pain, mucositis, anxiety, and depression. Conclusions: The integration of evidence-based complementary treatments allows for an effective response to the demand coming from cancer patients and combines safety and equity of access in public health systems.

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

    Science.gov (United States)

    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.

Between 2007 and 2010, 50 patients with recurrent and metastatic cervical cancer were treated using 3D-RT or IMRT. The median time interval between the initial treatment and the start of irradiation was 12 (6-51 months. Salvage surgery was performed before irradiation in 5 patients, and 38 patients received concurrent chemotherapy. Sixteen patients underwent 3D-RT, and 34 patients received IMRT. Median follow-up for all the patients was 18.3 months. Three-year overall survival and locoregional control were 56.1% and 59.7%, respectively. Three-year progression-free survival and disease-free survival were 65.3% and 64.3%, respectively. Nine patients developed grade 3 leukopenia. Grade 5 acute toxicity was not observed in any of the patients; however, 2 patients developed Grade 3 late toxicity. 3D-RT or IMRT is effective for the treatment of recurrent and metastatic cervical cancer, with the 3-year overall survival of 56.1%, and its complications are acceptable. Long-term follow-up and further studies are needed to confirm the role of 3D-RT or IMRT in the multimodality management of the disease.

    Full Text Available Cancer is a debilitating illness that affects more than one in every three Americans at sometime in their life time regardless of their social, cultural, ethnic, religious, or economic status. A few studies in the psychotherapy literature have investigated the impact of cancer on the personal and professional lives of psychotherapists. However, such investigations are yet unknown in medical or music therapy literature. In this descriptive phenomenological study, the researcher interviewed five American music therapists who have survived cancer and also work with patients in medical hospitals or hospice settings. The purpose of this study was to fully describe their lived experience of surviving cancer and examine how the cancer experience affected their clinical work thereafter. The data was analyzed using an open coding method from grounded theory which identified four major themes: (a personal significance; (b relational significance; (c musical significance and (d professional significance. The descriptions provided by these participants of their cancer experience as patients, survivors, and cancer surviving therapists, have revealed various psychosocial and physical issues encountered, and numerous coping methods they employed, and poignantly explained how their clinical approach evolved and expanded due to the personal experience of cancer. Specific issues in relation to countertransference, self-disclosure, and ways of developing empathic approaches without having such personal experience were discussed in addition to suggestions for future research.

  13. Mexican forest fires and their decadal variations

    Velasco Herrera, Graciela

    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.

    Full Text Available Objectives: We planned this study with the aim of obtainingknowledge about epidemiological characteristics of gynecologicalmalignancies followed up in our hospital.Materials and methods: In our study we analyzed 231patients that were operated with the appraisal diagnosis ofgynecological cancer in Gynecology and Obstetrics Departmentof Dicle University Medical Faculty between the datesof 2001, January and 2011, November.Results: The mostly diagnosed gynecological malignancywas ovarian cancers among the gynecological cancersseen in the first group compassing the period between theyear 2001 and the first half-term of the year 2006. In thesecond group compassing the period from the second halftermof the year 2006 to the end of the year 2011, ovariancancers were again the most frequently seen gynecologicalcancers. On the other hand it was found that there was anincrease in the percentage of endometrial cancers. Whilecases with advanced staged constituting the major part ofthe patients with ovarian cancer, it was seen that the majorityof the patients with endometrium cancer were consistingof stage 1 cases. In the 4 of 6 cases having endometriumcancer and applying with the complaint of pain, the diseasewas noticed in the advanced stage. Being the most frequentlyseen gynecological cancer all over the world andespecially in the societies with lower socio-economic status,the cervix cancer was taking place in the 3rd order afterendometrium cancer in terms of frequency in our region.Conclusion: Consequently, in the recent years the gynecologicalcancer showing the most frequent increase wasendometrium cancer in our region. The increase in the frequencyof obesity, relating with the reasons like the impropernutrition behavior, the increase in the socio-economic status,may be associated with the increase in the frequencyof endometrium cancer. The healthcare personals and thepublic body must be instructed to diagnose the gynecologicalcancer cases especially the

    Full Text Available BACKGROUND: Despite increasing cancer burden in Malawi, pathology services are limited. We describe operations during the first 20 months of a new pathology laboratory in Lilongwe, with emphasis on cancer diagnoses. METHODS AND FINDINGS: We performed a cross-sectional study of specimens from the Kamuzu Central Hospital pathology laboratory between July 1, 2011 and February 28, 2013. Patient and specimen characteristics, and final diagnoses are summarized. Diagnoses were categorized as malignant, premalignant, infectious, other pathology, normal or benign, or nondiagnostic. Patient characteristics associated with premalignancy and malignancy were assessed using logistic regression. Of 2772 specimens, 2758 (99% with a recorded final diagnosis were included, drawn from 2639 unique patients. Mean age was 38 years and 63% were female. Of those with documented HIV status, 51% had unknown status, and 36% with known status were infected. Histologic specimens comprised 91% of cases, and cytologic specimens 9%. Malignant diagnoses were most common overall (n = 861, 31%. Among cancers, cervical cancer was most common (n = 117, 14%, followed by lymphoma (n = 91, 11%, esophageal cancer (n = 86, 10%, sarcoma excluding Kaposi sarcoma (n = 75, 9%, and breast cancer (n = 61, 7%. HIV status was known for 95 (11% of malignancies, with HIV prevalence ranging from 9% for breast cancer to 81% for cervical cancer. Increasing age was consistently associated with malignancy [bivariable odds ratio 1.24 per decade increase (95% CI 1.19-1.29 among 2685 patients with known age; multivariable odds ratio 1.33 per decade increase (95% CI 1.14-1.56 among 317 patients with known age, gender, and HIV status], while HIV infection and gender were not.

    Full Text Available Introduction: Aflibercept in combination with FOLFIRI has been shown to improve overall survival in the pivotal VELOUR study. Aflibercept has not yet been marketed in India. Sanofi has made available this drug for Indian patients under a program called Named Patient Access Program (NPP. We present a limited clinical experience with the use of aflibercept at our center. Materials and Methods: We analyzed the data of the patients who received aflibercept under NPP. Aflibercept was given in combination with FOLFIRI as second-line for patients who progressed on oxaliplatin based therapy. Aflibercept was given at 4 mg/kg intravenous (IV every 15 days. Chemotoxicities were assessed as per CTCAE. Response evaluation was done every four cycles. Results: Five patients were enrolled. The median age was 34 years. The median number of aflibercept cycles administered was 12. Common grade 2/3 toxicities were mucositis, diarrhea, neutropenia thrombocytopenia, and hypertension seen in three (60%, three (60%, two (40%, two (40%, and one patient respectively. After four cycles, the response was assessed as: One complete remission (CR, three partial remissions (PR, and one progressive disease (PD. Three patients completed 12 cycles of chemotherapy and aflibercept. At the end of 12 cycles, one patient still in CR and two patients were in PR. Four patients were alive till date. Conclusion: As we had very less number of patients, it was very difficult to compare it with VELOUR data. It is one of option as second-line in metastatic colorectal cancer (mCRC who progressed on oxaliplatin chemotherapy. Mucositis, diarrhea, and hematological toxicity were the most common toxicity in our patient.

  19. Mexican plants and human fertility.

    Synthetic steroids are obtainable cheaply and in abundance from sapogenins, substances originating from plants of the Discorea family. Some 40 years ago, Russell Marker, an American chemist, discovered this source, which grows abundantly in Mexican jungles and is now exploited and cultivated commercially. Today synthetic steroids prepared from extracts from a wide range of vegetable sources are used in the treatment of rheumatoid arthritis, allergies, inflammatory diseases, sterility, and various heart conditions, and form the basis of modern oral contraceptives. Nevertheless, oral contraceptives in current use are still fairly costly, and women have to be educated in their use. What is needed urgently is a cheaper contraceptive pill with a long-term effect, and research is continuing. For example, scientists from the People's Republic of China have reported significant anti-fertility effects associated with 2 substances, anordin and dinordin, prepared with steroids derived from the sisal plants Agave sisilana and Agave americana. These agents, whose anti-fertility properties have been confirmed by scientists in Sweden and the United States, constitute a new family of contraceptives with the great advantage of having to be taken only once or twice instead of 20 times per month necessary with the ordinary pill. Also from China, scientists have reported the effectiveness of gossypol as an orally administered male contraceptive, although gossypol is not a steroid. It may become, however, a leading candidate for a male contraceptive.

  20. Mexican American women's adherence to hemodialysis treatment: a social constructivist perspective.

    2009-07-01

    Mexican Americans have as much as a six-times greater risk of end-stage renal disease (ESRD) than non-Hispanic white Americans, and women show a faster rate of decline in diabetic renal functioning. The leading treatment for ESRD is hemodialysis, an intensive, complex treatment regimen associated with high levels of patient nonadherence. Previous studies of patient adherence have adopted a biomedical, practitioner-oriented approach focused on performance of fixed behaviors and ignoring contextual and motivational factors. The author describes a social constructivist approach to understanding how female Mexican American dialysis patients experience their disease, the treatment regimen, and the consequences of that experience. Mexican American women's perceptions and psychosocial factors were examined to understand what these women viewed as important to their realities as dialysis patients. Poverty, longer treatment history, and immigrant status emerged as factors that appeared to influence treatment nonadherence. Perceived identity losses, heightened awareness of mortality and family dysfunction emerged as themes that participants viewed as preeminent in their day-to-day lives. A social constructivist perspective is highly compatible with social work principles of person-in-environment and starting where the client is. This perspective provides a valuable framework for informing social work practice with this special population of Mexican American dialysis patients.

    2012-02-01

    BACKGROUND: Follow-up of patients with an initial negative prostate biopsy, but surrounding whom a suspicion of prostate cancer persists, is difficult. In addition, debate exists as to the optimal technique for repeat prostate biopsy. AIMS: To assess the cancer detection rate on repeat prostate biopsy. METHODS: We reviewed patients who underwent prostate biopsy in our department in 2005 who had >or=1 previous biopsy within the preceding 5 years. Cancer detection rate on repeat biopsy and the influence of the number of biopsy cores were recorded. RESULTS: Cancer detection rate on repeat biopsy was 15.4%, with approximately 60% detected on the first repeat biopsy, but approximately 10% not confirmed until the fourth repeat biopsy. Gleason score was similar regardless of the time of diagnosis (6.1-6.5). Mean interval between first biopsy and cancer diagnosis (range 18-55 months) depended on the number of repeat procedures. There was an association between the number of biopsy cores and cancer detection. CONCLUSIONS: This study supports the practice of increasing the number of cores taken on initial and first repeat biopsy to maximise prostate cancer detection and reduce the overall number of biopsies needed.

    Full Text Available Objetive: The Population-based Cancer Registry of Cali aims to report all new cases in permanent residents within the limits of the city of Cali. Time trends of cancer incidence and mortality are described. The registry has been in continuous operation for 50 years. Methods: Cancer cases reports are obtained actively by visiting all sources of information: hospitals, pathology departments, hematology laboratories, radiotherapy centers, government offices where death certificates are processed and physician’s offices. It is estimated that the reporting is at least 95% complete. Results: Drastic decreases are documented in rates for tumors causally related to infectious agents, especially cancers of the uterine cervix and the stomach. Gradual increases are documented in rates of tumors linked to affluence and the metabolic syndrome, especially cancers of the colon and the female breast. An unexpected increase in the incidence of papillary carcinoma of the thyroid gland in women is reported. Tobacco-related cancers, especially cancer of the lung, showed marked increase in incidence rates around 1970, apparently the beginning of an epidemic similar to the one reported in Western societies. But the increase in incidence stopped around 1980, resulting from a strong anti-smoking campaign launched in Colombia in the 1970s. Conclusions: The findings have influenced prevention strategies implemented by public health authorities, specially the establishment of a city-wide program to prevent cervix cancer via widespread use of vaginal cytology and anti-smoking campaigns. Also, new population-based cancer registries have been established in other Colombian cities as well as in Ecuador.

  5. Mexican petroleum and US national security

    Energy Technology Data Exchange (ETDEWEB)

    Fagen, R.R.

    US vulnerability to energy supplies is reviewed in terms of action taken by the Organizaion of Petroleum Exporting Countries (OPEC) during the 1970s and the outlook for supply and price disruptions in the 1980s. The US position is then related to the Mexican petroleum boom and the benefits that increasing exports from a non-OPEC country like Mexico can have on world oil trade. US political and security interests will encourage a rapid increase in Mexican production, and the US will be concerned with how Mexico develops its relationships with the US and with other oil-producing countries. Changing economic and social relationships are inevitable and could lead to serioUS political unrest over questions of equity and immigrations. The difficulty of articulating US security interests without interfering in Mexican domestic affairs will require careful diplomacy.

    Full Text Available At the frontline of México’s “war on drugs” is the Mexican-U.S. border city of Cd. Juárez, Chihuahua, which has become internationally known as the “murder capital of the world.” In Juárez, which neighbors El Paso, Texas, United States, estimates of the murders in Juárez are as high as 7,643 between 2006 and 2011, leaving approximately 10,000 orphans. Juárez has also experienced an exodus of approximately 124,000 people seeking safety, some migrating to the Mexican interior and others to the U.S., particularly along the U.S.-México border. Based on 63 in-depth interviews with Juárez-El Paso border residents, along with ethnographic observations, we examine the implications of the “war on drugs” on transnational movements and on the initial settlement of those escaping the violence. In particular, we construct a typology of international migrants who are represented in the Juárez exodus: the Mexican business elite, the “Refugees without Status,” and those who resided in México but who are U.S. born or have legal permanent residency in the U.S. This article highlights the role of transnational capital in the form of assets and income, social networks in the U.S., and documentation to cross the port of entry into the U.S. legally, in easing migration and initial settlement experiences in the U.S.

    On January 1, 2011, Princess Margaret Cancer Centre (PM) - University Health Network (UHN) began a five-year partnership agreement with the Kuwait Ministry of Health's Kuwait Cancer Control Center (KCCC) to enhance cancer care services. Over the course of the partnership, opportunities for improvement were identified by UHN experts in order to accelerate KCCC's development toward subspecialty cancer care. Many of these opportunities involved building a robust infrastructure to support foundational hospital operation processes and procedures. Harnessing UHN's own successes in accreditation, the partnership took advantage of the national accreditation mandate in Kuwait to initiate a quality program and drive clinical improvement at KCCC. This resulted in improved staff engagement, better awareness and alignment of administration with clinical management and a stronger patient safety culture. This article discusses the successes and lessons learned at KCCC that may provide insight to healthcare providers implementing Accreditation Canada International's accreditation framework in other countries and cultures.

    Full Text Available Dr Moushumi Lodh is a physician who was diagnosed with breast cancer in the year 2009. In this interview, she speaks to childhood friend and freelance medical writer, Dr Natasha Das about her life with cancer. When she was 22, Moushumi had a fibroadenoma removed from her breast. She had noticed a small new lump in her breast 16 years later and ignored it for over a year believing that it was one of those benign lumps again. She believes an early diagnosis could have paved way for better treatment options for her. In this interview, she urges women to be better aware, to do regular self-exams and to go for screening. If diagnosed with cancer, she says, one should not lose heart but should fight it with a positive spirit. Cancer, after all, is only another chronic disease that needs lifelong treatment and care.

    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.

However, a large group of migrants in different economically developed countries have successfully launched businesses of diverse nature and volume. This is why entrepreneurship of migrants is an issue that has received increasing attention in recent years. Compared to other immigrant groups in the United States, Mexicans show low levels of entrepreneurial activity. The aim of this paper is to, through a general literature review of official statistical data, a preliminary analysis of mexican migrant entrepreneurship in the United States, that is to say in recent years has been growing in importance.

    To improve cancer pain management, the Medical Oncology Department of Sun Yat-sen University Cancer Center (SYSUCC) launched the Good Pain Management (GPM) Ward Program, which has been recognized by the Chinese Ministry of Health and promoted throughout the nation. This retrospective case-control study was designed to evaluate the effectiveness of the program. Patients diagnosed with malignant solid tumors with bone metastasis were eligible. Patients who were admitted 6 months before the initiation of the GPM program were used as the control group, and patients admitted 6 months after the initiation of the program were used as the GPM group. The pain-reporting rate and pain management index (PMI) were calculated. The pain levels before and after pain management were compared. A total of 475 patients (244 in the control group and 231 in the GPM group) were analyzed. The pain-reporting rate of the GPM group was significantly higher than that of the control group (62.8% vs. 37.7%,P< 0.001). The PMI of the GPM group was significantly higher than that of the control group (0.083 vs. -0.261,P< 0.001). Therefore, the GPM Ward Program improved the pain management of cancer patients and provided experience for improving cancer pain management in the future.

    Promoting health and well-being among individuals of advancing age is a significant issue due to increased incidence of cancer among older adults. This study demonstrates the benefits of expecting positive outcomes and participating in volunteer activities among older adults with cancer. We used a nationally representative sample of 2,670 individuals who have experienced cancer from the 2008 wave of the Health and Retirement Study. We constructed a structural equation model to explore the associations of optimism, volunteerism, life satisfaction, and psychological well-being. The level of optimism was a significant predictor of volunteerism, which in turn affected life satisfaction and psychological well-being. The level of engagement in volunteer activities was found to have significant path coefficients toward both life satisfaction and psychological well-being. Our study provides evidence that older adults who have experienced cancer and maintained a positive outlook on their lives and engaged in personally meaningful activities tended to experience psychological well-being and life satisfaction.

    Objective To establish an international patient-reported outcomes (PROMs) study among prostate cancer survivors, up to 18 years postdiagnosis, in two countries with different healthcare systems and ethical frameworks. Design A cross-sectional, postal survey of prostate cancer survivors sampled and recruited via two population-based cancer registries. Healthcare professionals (HCPs) evaluated patients for eligibility to participate. Questionnaires contained validated instruments to assess health-related quality of life and psychological well-being, including QLQ-C30, QLQ-PR25, EQ-5D-5L, 21-question Depression, Anxiety and Stress Scale (DASS-21) and the Decisional Regret Scale. Setting Republic of Ireland (RoI) and Northern Ireland (NI). Primary outcome measures Registration completeness, predictors of eligibility and response, data missingness, unweighted and weighted PROMs. Results Prostate cancer registration was 80% (95% CI 75% to 84%) and 91% (95% CI 89% to 93%) complete 2 years postdiagnosis in NI and RoI, respectively. Of 12 322 survivors sampled from registries, 53% (n=6559) were classified as eligible following HCP screening. In the multivariate analysis, significant predictors of eligibility were: being ≤59 years of age at diagnosis (p<0.001), short-term survivor (<5 years postdiagnosis; p<0.001) and from RoI (p<0.001). 3348 completed the questionnaire, yielding a 54% adjusted response rate. 13% of men or their families called the study freephone with queries for assistance with questionnaire completion or to talk about their experience. Significant predictors of response in multivariate analysis were: being ≤59 years at diagnosis (p<0.001) and from RoI (p=0.016). Mean number of missing questions in validated instruments ranged from 0.12 (SD 0.71; EQ-5D-5L) to 3.72 (SD 6.30; QLQ-PR25). Weighted and unweighted mean EQ-5D-5L, QLQ-C30 and QLQ-PR25 scores were similar, as were the weighted and unweighted prevalences of depression, anxiety and

    The Mexican cardioangiology started in the nineteen century thanks to first endeavors of surgeons and physicians related to local academies and to School of Medicine, established in 1833 by Dr. Valentin Gómez Farías. Dr. Manuel Carpio, the future first head of department of physiology in this school, translated to Spanish language and published, in 1823, the article On pectoriloquo of the French physician Marat and later performed some experiments on the heart' motion. During the Secont Empire (1864-1867), the physician Samuel von Basch performed studies to define the arterial hypertension, called by him "latent atherosclerosis", i.e. the "essential hypertension". Once he had returned to his country, he invented in 1880, a sphygmomanometer of mercury column, that was the model for the instrument constructed by the Italian physician Scipione Riva-Rocci and presented in 1896. In our time, Dr. Demetrio Sodi Pallares systematized a metabolic therapy called "polarizing therapy", i.e. capable of repolarizing the heart's cells partly depolarized due to hypoxia or direct aggressions. These were the first steps in Mexico on the way to a promising medicine starting and the great adventure of Mexican cardiology.

    Full Text Available Cervical cancer continues to be a major public health problem in India in the absence of wide spread organised cervical screening programs. Visual inspection of the cervix with acetic acid (VIA is an effective, inexpensive screening test that can be combined with simple treatment procedures for early cervical lesions, provided by trained health workers. We report 7 years experience in early detection of cervical cancer and pre-cancers using the VIA test in a community-based program in rural Andhra Pradesh, India where there are no existing organised cervical screening programs. Materials and Methods: Eligible women aged between 26 and 60 were opportunistically screened by trained health wor kers using the VIA test. Women who tested positive were further evaluated and those with cervical lesions were treated either by cryotherapy in the screening clinic or referred to a higher center. Results: A total of 18,869 women were screened by a single round of VIA testing with a positive rate of 10.75%. Biopsy proven high-grade squamous intraepithelials (HSILs were 90 (0.48% and low-grade squamous intraepithelials (LSILs were 43 (0.28%. The overall prevalence of cervical intraepithelial neoplasia (CIN 2+ lesion rate is 1.05%. A total of 312 (1.65% cryotherapies were done and 49 women underwent hysterectomy. Conclusions: VIA by trained female health workers is a safe, acceptable, and effective test that can save lives from cervical cancer even in remote areas with few resources. These results have important implications for efficient service delivery in cervical screening programs in low-resourced settings.

    Full Text Available Background: Lung cancer remains a major cause of morbidity and mortality worldwide, accounting for more deaths than any other cancer cause. Aim: The aim of this study was to analyze the clinical profile and the epidemiological trends in lung cancer patients from a single centre with an emphasis on the smoking practices. Materials and Methods: This is a retrospective analysis of prospectively collected data of 258 consecutive hospital in-patients with a proven diagnosis of lung cancer at a tertiary care oncology centre between 2003 and 2007. Results: The median age of patients in our study was 56 years; the male to female ratio was approximately 3.5:1. Non-small-cell lung cancer (NSCLC was the predominant histology in 224 patients; the histology in the remaining 34 patients was small-cell carcinoma. Within NSCLC, the most common histology was adenocarcinoma followed by squamous cell carcinoma. One hundred and two patients were never-smokers as compared to 156 patients who were ever-smokers. Among the smokers, the majority of them were found to be cigarette smokers compared to 28.2% bidi smokers. There was a very significant correlation found with adenocarcinoma among nonsmokers, and with squamous cell carcinoma among the smokers compared to non-smokers. Conclusions: Our study suggests that the epidemiology of lung cancer in India is possibly changing, with close to 40% of our lung cancer patients being nonsmokers. More importantly, our study reflects the global trend of rise in adenocarcinoma histology. These observations need to be substantiated in similar studies of larger magnitude, preferably population-based.

    Purpose: The National Cancer Institute (NCI) Community Cancer Centers Program (NCCCP) began in 2007; it is a network of community-based hospitals funded by the NCI. Quality of care is an NCCCP priority, with participation in the American Society of Clinical Oncology Quality Oncology Practice Initiative (QOPI) playing a fundamental role in quality assessment and quality improvement (QI) projects. Using QOPI methodology, performance on quality measures was analyzed two times per year over a 3-year period to enhance our implementation of quality standards at NCCCP hospitals. Methods: A data-sharing agreement allowed individual-practice QOPI data to be electronically sent to the NCI. Aggregated data with the other NCCCP QOPI participants were presented to the network via Webinars. The NCCCP Quality of Care Subcommittee selected areas in which to focus subsequent QI efforts, and high-performing practices shared voluntarily their QI best practices with the network. Results: QOPI results were compiled semiannually between fall 2010 and fall 2013. The network concentrated on measures with a quality score of ≤ 0.75 and planned voluntary group-wide QI interventions. We identified 13 measures in which the NCCCP fell at or below the designated quality score in fall 2010. After implementing a variety of QI initiatives, the network registered improvements in all parameters except one (use of treatment summaries). Conclusion: Using the NCCCP as a paradigm, QOPI metrics provide a useful platform for group-wide measurement of quality performance. In addition, these measurements can be used to assess the effectiveness of QI initiatives. PMID:25538082

    Drawing on data generated by life history interviews and fieldwork observations we illuminate the ways in which a young elite athlete named David (a pseudonym) gave meaning to his experiences of cancer that eventually led to his death. Central to this process were the ways in which David utilized both social comparisons and a narrative map provided by the published autobiography of Lance Armstrong (2000). Our analysis reveals the selective manner in which social comparison processes operated around the following key dimensions: mental attitude to treatment; the sporting body; the ageing body; and physical appearance. The manner in which different comparison targets were chosen, the ways in which these were framed by Armstrong's autobiography, and the work that the restitution narrative as an actor did in this process are also examined. Some reflections are offered regarding the experiential consequences of the social comparison processes utilized by David when these are shaped by specific forms of embodiment and selective narrative maps of cancer survival.

    Full Text Available Purpose. Improvement of the results of treatment of patients with locally advanced and metastatic gastric cancer. Material and methods. From the 2010–2014 we performed 30 surgeries using techniques HICT. Among patients there were 17 men and 13 women. The median of age was 50 years. Locally advanced gastric cancer (T4a-T4b was observed in 22 cases, including 4 patients in the emergency immunocytochemical study with peritoneal lavage detected cancer-free (Cyt + cells in the abdominal cavity. The group of patients with metastatic gastric cancer accounted for 8 patients. Narrow carcinomatosis (P1 was 4 cases, carcinomatosis (P2-P3 — 4. Adjuvant systemic chemotherapy in the study group was not carried out. In the control group No 1 (n = 51 performed surgery alone, without additional anticancer therapy. In the control group No 2 (n = 66, a combined treatment (surgery + chemotherapy. Results. Follow-up median was 25 months. Overall 1-year survival rate for all three groups was 55%, 39% and 52%, respectively. Median survival in the intervention group versus 21.4 months in the 8 and 12 months, respectively. The most effective HICT is shown for patients with locally advanced gastric cancer. In the study group, median overall survival was 29 months. The survival rate of 1-, 2-, 3-year-old was equal to 68%, 61% and 42%. In the first control group, 1-year survival of 45%. None of the patients did not survive 2 years. In the second control group, one-year survival rate was 60%, 2-year survival is not. Results of treatment of metastatic gastric cancer proved to be more modest. In the main group the median survival was 10 months, compared with 6 and 7 months of the two control groups. There were no statistically significant differences. Conclusions. 1. Availability of limited dissemination, free cancer cells in the abdominal cavity, as well as a massive defeat of serous membrane of the stomach can be seen as indications for HICT in gastric cancer. 2.

    Most previous studies have linked cancer-macrophage fusion with tumor progression and metastasis. However, the characteristics of hybrid cells derived from oral cancer and endothelial cells and their involvement in cancer remained unknown. Double-immunofluorescent staining and fluorescent in situ hybridization (FISH) were performed to confirm spontaneous cell fusion between eGFP-labeled human umbilical vein endothelial cells (HUVECs) and RFP-labeled SCC9, and to detect the expression of vementin and cytokeratin 18 in the hybrids. The property of chemo-resistance of such hybrids was examined by TUNEL assay. The hybrid cells in xenografted tumor were identified by FISH and GFP/RFP dual-immunofluoresence staining. We showed that SCC9 cells spontaneously fused with cocultured endothelial cells, and the resultant hybrid cells maintained the division and proliferation activity after re-plating and thawing. Such hybrids expressed markers of both parental cells and became more resistant to chemotherapeutic drug cisplatin as compared to the parental SCC9 cells. Our in vivo data indicated that the hybrid cells contributed to tumor composition by using of immunostaining and FISH analysis, even though the hybrid cells and SCC9 cells were mixed with 1:10,000, according to the FACS data. Our study suggested that the fusion events between oral cancer and endothelial cells undergo nuclear fusion and acquire a new property of drug resistance and consequently enhanced survival potential. These experimental findings provide further supportive evidence for the theory that cell fusion is involved in cancer progression.

    We report a rare case of Pseudo-Meigs' Syndrome caused by ovarian metastasis from sigmoid colon cancer, which was accompanied by peritoneal dissemination. A 58-year-old female patient presented with massive right pleural effusion, ascites and a huge pelvic mass. Under the diagnosis of an advanced ovarian tumor, bilateral oophorectomy was performed and sigmoidectomy was also carried out after intraoperative diagnosis of peritoneal dissemination involving the sigmoid colon. How- ever, immunohistochemical staining revealed that the ovarian lesions were metastasis from the primary advanced colon cancer. Postoperatively, ascites and pleural effusion subsided, and the diagnosis of Pseudo-Meigs' Syndrome due to a metastatic ovarian tumor from colon cancer was determined. The patient is now undergoing a regimen of chemotherapy for colon cancer without recurrence of ascites or hydrothorax 10 mo after the surgery. Pseudo-Meigs' Syndrome due to a metastaticovarian tumor from colon cancer is rare but clinically important because long-term alleviation of symptoms can be achieved by surgical resection. This case report suggests that selected patients, even with peritoneal dissemination, may obtain palliation from surgical resection of metastatic ovarian tumors.

    To evaluate the effect of radiologist experience on the risk of false-positive results in population-based breast cancer screening programmes. We evaluated 1,440,384 single-read screening mammograms, corresponding to 471,112 women aged 45-69 years participating in four Spanish programmes between 1990 and 2006. The mammograms were interpreted by 72 radiologists. The overall percentage of false-positive results was 5.85% and that for false-positives resulting in an invasive procedure was 0.38%. Both the risk of false-positives overall and of false-positives leading to an invasive procedure significantly decreased (p < 0.001) with greater reading volume in the previous year: OR 0.77 and OR 0.78, respectively, for a reading volume 500-1,999 mammograms and OR 0.59 and OR 0.60 for a reading volume of >14,999 mammograms with respect to the reference category (<500). The risk of both categories of false-positives was also significantly reduced (p < 0.001) as radiologists' years of experience increased: OR 0.96 and OR 0.84, respectively, for 1 year's experience and OR 0.72 and OR 0.73, respectively, for more than 4 years' experience with regard to the category of <1 year's experience. Radiologist experience is a determining factor in the risk of a false-positive result in breast cancer screening. (orig.)

    2012-01-01

    Full Text Available Abstract Background Biology, biomedicine and healthcare have become data-driven enterprises, where scientists and clinicians need to generate, access, validate, interpret and integrate different kinds of experimental and patient-related data. Thus, recording and reporting of data in a systematic and unambiguous fashion is crucial to allow aggregation and re-use of data. This paper reviews the benefits of existing biomedical data standards and focuses on key elements to record experiments for therapy development. Specifically, we describe the experiments performed in molecular, cellular, animal and clinical models. We also provide an example set of elements for a therapy tested in a phase I clinical trial. Findings We introduce the Guidelines for Information About Therapy Experiments (GIATE, a minimum information checklist creating a consistent framework to transparently report the purpose, methods and results of the therapeutic experiments. A discussion on the scope, design and structure of the guidelines is presented, together with a description of the intended audience. We also present complementary resources such as a classification scheme, and two alternative ways of creating GIATE information: an electronic lab notebook and a simple spreadsheet-based format. Finally, we use GIATE to record the details of the phase I clinical trial of CHT-25 for patients with refractory lymphomas. The benefits of using GIATE for this experiment are discussed. Conclusions While data standards are being developed to facilitate data sharing and integration in various aspects of experimental medicine, such as genomics and clinical data, no previous work focused on therapy development. We propose a checklist for therapy experiments and demonstrate its use in the 131Iodine labeled CHT-25 chimeric antibody cancer therapy. As future work, we will expand the set of GIATE tools to continue to encourage its use by cancer researchers, and we will engineer an ontology to

    This article assesses whether international migration from Mexico affects the marital, fertility, schooling, and employment outcomes of the Mexican women who remain behind by exploiting variation over time as well as across Mexican states in the demographic imbalance between men and women. I construct a gauge of the relative supply of men for women of different age groups based on state-level male and female population counts and the empirically observed propensity of men of specific ages to marry women of specific ages. Using Mexican census data from 1960 through 2000, I estimate a series of models in which the dependent variable is the intercensus change in an average outcome for Mexican women measured by state and for specific age groups, and the key explanatory variable is the change in the relative supply of men to women in that state/age group. I find that the declining relative supply of males positively and significantly affects the proportion of women who have never been married as well as the proportion of women who have never had a child. In addition, states experiencing the largest declines in the relative supply of men also experience relatively large increases in female educational attainment and female employment rates. However, I find little evidence that women who do marry match to men who are younger or less educated than themselves.

    Full Text Available Mexican pharmaceutical market is the most important in Latin America and a significant number of global firms have different business activities in this country: production, licensing of patents, alliances with Mexican firms, distribution facilities or partnerships, etc. In terms of innovation, global pharmaceutical industry has passed through structural changes mainly of technological and institutional nature. These changes have been influential along the whole value chain and have triggered transformations in firm's organization, market structure and sector's investments. Mexico's industry, in spite of having a very attractive domestic market, has serious limitations for technology development. Very little resources are invested in R&D and lack of articulation between research labs and industry provoke that Mexico has only exceptional innovation achievements and a high technological dependence. At the same time, some Mexican companies have developed new strategies to be competitive in open markets and have shown that a combination of competitive intelligence, rapid adoption of technologies, collaboration with advanced firms and research institutes, permanent training and continuous improvement are key factors for success. This paper deals with the results of a piece of research aimed at developing a model for the effective transfer of technology for Mexican pharmaceutical firms, with a strong component of knowledge and skills to manage the flows of information, people and technologies among firms, research labs, universities and other health organizations.

    Testicular cancer affects men mostly in their reproductive age with a cure rate over 90%. Preserved fertility is one of the main concerns of the survivors. To further elucidate the question of fertility after anticancer treatment for testicular cancer, we performed a survey among patients who underwent sperm cryopreservation procedure in our department. A structured questionnaire was designed to collect data on demography, anticancer treatment, histological type of cancer, family planning intentions and fertility prior to and after treatment. During a period of 11 years 86 men underwent semen cryopreservation before starting chemo-or radiotherapy. Fifty-nine of them consented to participate in the study. The average length of follow up was 4.6 +/- 3.8 years. In case of 11.9% of the patients their banked sperm was used, which led to live birth in 57% of the couples. The partners of 6 patients became pregnant after in vitro fertilization (IVF) resulting in 4 live births and 2 miscarriages. The spontaneous pregnancy rate was 22%. Spontaneous pregnancy occurred in 13 partners resulting in 18 pregnancies followed by 12 live births, 2 artificial abortions and 4 miscarriages. We could not prove any association between preserved fertility and anticancer treatment or the histological type of the cancer. In conclusion, although spontaneous pregnancy rate is remarkably high after anticancer treatment for testicular cancer, the risk of infertility after receiving gonadotoxic treatment cannot be predicted. Cryopreservation is a safe and effective method to preserve fertility in these cases. As a result we strongly recommend discussing the advantages of semen cryopreservation with all patients awaiting treatment for testicular cancer.

    {sup 166}Ho is a good therapeutic radionuclide because of its suitable half-life (26.8 hours), high beta energy and 6% gamma ray for imaging. Chitosan is a kind of N-glucosamine with 400 to 500 kD MW, which chelates metal ions and degrades slowly in vivo. As a preclinical studies, we performed cytotoxic effect of {sup 166}Ho-chitosan in a variety of cancer cell lines derived from stomach or ovarian cancer based on MTT assay and HTCA method. To evaluated the absorbed dose to the cavitary wall from {sup 166}Ho-chitosan, intraperitoneal administration of {sup 166}Ho-chitosan in the rat and simulation of energy transfer from the beta particles to the cavity wall using the Monte Carlo code EGS4 was done, and used as a standard for the planning therapy. Intracavitary {sup 166}Ho-chitosan therapy were tried in peritoneal metastatic ovarian and stomach cancers and cystic brain tumors. Intraarterial injection in inoperable primary liver cancer was also tried. As a radiation synovectomy agent, biocompatibility study in the knee joints of rabbits were performed. {sup 166}Ho-chitosan showed synergistic effects with 5-FU or cisplatin in vitro. 97-99% of {sup 166}Ho-chitosan was localized within the peritoneal cavity, and more than 90% of {sup 166}Ho-chitosan was attached to the peritoneal wall. Partial response were observed in 4 among 5 patients with ovarian cancer without severe toxicity. In the cystic brain tumor, 5 of 8 cysts were shrunken in size with thinning of the wall, 2 out of 8 showed growth retardation. In the primary liver cancer, radioactivity was distributed in the teritory of selected hepatic arterial branch, and partial responses were observed in 2 cases. In the knee joints of the rabbits, more than 98% of {sup 166}Ho-chitosan remained in the joint cavity and was stable upto 1 week. 49 refs., 22 tabs. (author)

    Laparoscopic gastrointestinal surgery with lymphadenectomy is rarely performed for multiple gastrointestinal cancers. We report four patients undergoing laparoscopic surgery for synchronous cancer of the stomach and colon. Resection of each organ with lymphadenectomy was performed by each specialist and the region of the lymphadenectomy was determined according to the lesion of cancer and its depth. The selection of gastric anastomosis, whether intracorporeal or extracorporeal, depended on the resecting areas of the large bowel to allow a small incision. All four cases were male with the median age of 69 (range 59-77) years. The median number of trocars used were 6 (range 5-8) and median length of incision was 4.5 cm (range 4-4.5 cm). The median operative time and blood loss were 495.5 minutes (range 390-605) and 88 g (range 36-245), respectively. In all four cases, laparoscopic surgery with a lymphadenectomy on each region was successfully accomplished according to the respective progression stage. Anastomosis was completed with a small incision by using techniques and devices to provide a variation of anastomosis methods and incision positions. Laparoscopic surgery with lymphadenectomy was also undertaken for a patient with gastric remnant cancer and colorectal cancer. The median length of the postoperative hospital stay was 14.5 days (range 12-29). No complications were observed after the surgery. There was no case of recurrence during a median follow-up of 84.3 months (range 54.9-111.5). Laparoscopic surgery was feasible for patients with double cancer of the stomach and colon.

    Eighty patients, with newly diagnosed unifocal breast cancer and with no axillary metastases verified by ultrasonography, underwent sentinel lymph node (SLN) and subsequent axillary lymph node dissection. To identify the SLN, we used a combination of Tc-99m labelled colloid (Albures) and blue dye...... as SLNs that tested negative but with higher nodes that tested positive. If SLN biopsy is accepted as a routine procedure and when the exact indications are defined, the method described probably could be offered to the majority of breast cancer patients....

  16. Distant Neighbours: Different Visions about Mexican Archaeology

    2014-05-01

    Full Text Available In 1972, Mexican archaeology experienced a major transformation due to the enactment of a Federal Law about archaeological, artistic, and historical monuments and zones, which changed the Mexican Government’s administration of Mexican archaeological heritage. In 1972, in West Mexico, an active group of archaeologists from the U.S.A. was working. They came from several universities and were also members of an academic association, the West Mexican Society for Advanced Study, that was based in Ajijic, Mexico, and comprised both U.S. and Mexican archaeologists. This group wrote to the government about their views of the new laws, and the government department concerned with their implementation, the Mexican National Institute of Anthropology and History (INAH – Instituto Nacional de Antropología e Historia, then responded with the Mexican Government’s official standpoint. In this paper, we analyze the positions of the West Mexican Society for Advanced Study, and INAH. We observe the sociopolitical and academic contexts from both U.S. and Mexican perspectives, and we offer explanations about their opposing views. We consider this episode to be a manifestation of the ideas circulating between U.S. and Mexican archaeologies.En 1972 la arqueología mexicana tuvo un cambio radical. En ese año fue promulgada la Ley Federal de Monumentos y Zonas Arqueológicos, Artísticos e Históricos. Esta ley cambió la manera en que el gobierno mexicano administraba el patrimonio arqueológico nacional. En dicho año, en el occidente de México, estuvo trabajando un grupo muy activo de arqueólogos estadounidenses, que si bien procedían de diversas universidades, también fueron miembros de una institución académica. La Sociedad de Estudios Avanzados del Occidente de México, con sede en Ajijic, México, reunió tanto a arquéologos estadounidenses como mexicanos. Los primeros escribieron un documento que contenía sus opiniones sobre la nueva ley y lo

    Full Text Available Abstract Background Knowledge about the quality and organisation of care to terminally ill cancer patients with a relatives' view in a primary health care setting is limited. The aim of the study is to analyse experiences and preferences of bereaved relatives to terminally ill cancer patients in a primary care setting to explore barriers and facilitators for delivery of good palliative home care. Methods Three focus group interviews with fourteen bereaved relatives in Aarhus County, Denmark. Results Three main categories of experience were identified: 1 The health professionals' management, where a need to optimize was found. 2 Shared care, which was lacking. 3 The relatives' role, which needs an extra focus. Conclusion Relatives experience insufficient palliative care mainly due to organizational and cultural problems among professionals. Palliative care in primary care in general needs improvement and attention should be drawn to the "professionalization" of the relatives and the need to strike a balance between their needs, wishes and resources in end-of-life care and bereavement.

    Full Text Available Objective. To determine the prevalence of the smoking habit among Mexican physicians as well as some of their attitudes and information on specific issues concerning smoking. Material and methods. In 1993, a survey was carried out among 3 568 physicians of the three major official health care institutions in Mexico City. A questionnaire designed for The Mexican National Survey of Addictions (ENA 1993 was used. Prevalence of cigarette smoking, age of onset, number of cigarettes per day; also information and attitudes concerning smoking were assessed. Results. The mean age was 37, 66% were males. Of the 3,488 (98% surveyed, 26.9% were smokers (62% daily, 20.6% were ex-smokers and 52.5% non-smokers. There were differences related to age and sex (p< 0.05. Of daily smokers, 36% smoked between 1 and 5 cigarettes. There was a significant trend among ex-smokers that linked the time they had ceased smoking with the fear to start smoking again. Physicians were well informed of the relationship between cigarette smoking and lung cancer. Over 80% considered tobacco an addictive drug but only 65% were in favor of banning smoking from their workplaces and over 10% were not aware that it is forbidden to smoke inside health care facilities. Conclusions. These results differ from other studies that find the prevalence of smoking among physicians lower than in the general population. Our study revealed a greater prevalence of the smoking habit among female physicians and the number of cigarettes smoked per day was greater than in the general population regardless of sex.

  19. Using patients’ experiences to identify priorities for quality improvement in breast cancer care: patient narratives, surveys or both?

    2012-08-01

    Full Text Available Abstract Background Patients’ experiences have become central to assessing the performance of healthcare systems worldwide and are increasingly being used to inform quality improvement processes. This paper explores the relative value of surveys and detailed patient narratives in identifying priorities for improving breast cancer services as part of a quality improvement process. Methods One dataset was collected using a narrative interview approach, (n = 13 and the other using a postal survey (n = 82. Datasets were analyzed separately and then compared to determine whether similar priorities for improving patient experiences were identified. Results There were both similarities and differences in the improvement priorities arising from each approach. Day surgery was specifically identified as a priority in the narrative dataset but included in the survey recommendations only as part of a broader priority around improving inpatient experience. Both datasets identified appointment systems, patients spending enough time with staff, information about treatment and side effects and more information at the end of treatment as priorities. The specific priorities identified by the narrative interviews commonly related to ‘relational’ aspects of patient experience. Those identified by the survey typically related to more ‘functional’ aspects and were not always sufficiently detailed to identify specific improvement actions. Conclusions Our analysis suggests that whilst local survey data may act as a screening tool to identify potential problems within the breast cancer service, they do not always provide sufficient detail of what to do to improve that service. These findings may have wider applicability in other services. We recommend using an initial preliminary survey, with better use of survey open comments, followed by an in-depth qualitative analysis to help deliver improvements to relational and functional aspects of patient

    Full Text Available Stereotactic Ablative Body Radiotherapy (SABR is a newer method of ultra hypo fractionated radiotherapy that uses combination of image guided radiotherapy (IGRT and intensity modulated radiotherapy(IMRT or volumetric modulated arc therapy(VMAT, to deliver high doses of radiation in a few fractions to a target, at the same time sparing the surrounding organs at risk(OAR.SABR is ideal for treating small volumes of disease and has been introduced in a number of disease sites including brain, lung, liver, spine and prostate. Given the radiobiological advantages of treating prostate cancer with high doses per fraction, SABR is becoming a standard of care for low and intermediate risk prostate cancer patients based upon the results from Sunny Brook and also the US-based prostate SABR consortium. This review examines the development of moderate and ultra hypo fractionation schedules at the Odette Cancer centre, Sunnybrook Health Sciences. Moderate hypo fractionation protocol was first developed in 2001 for intermediate risk prostate cancer and from there on different treatment schedules including SABR evolved for all risk groups.

MATERIAL Y MÉTODOS: A través del Sistema de Información Médico Operativa del IMSS, se conformó una cohorte de pacientes con diagnóstico reciente en 2002 que recibió seguimiento hasta finales de 2006. Se identificó el uso de recursos y se le adjudicó el costo de atención del IMSS. RESULTADOS: Sólo 14% se diagnosticó en fase I y 48% en las fases III-IV. El costo de atención promedio por año-paciente se estimó en 110 459 pesos y para las mujeres diagnosticadas en 2002 la etapa I tuvo un costo de 74 522 pesos, comparado con 102 042 en la etapa II, 154 018 en la etapa III y 199 274 en la IV. CONCLUSIONES: El cáncer mamario representa un presupuesto significativo en el IMSS y entre más tardía es la etapa de detección, más altos resultan los costos económicos por año-paciente y más baja la probabilidad de sobrevida a cinco años.OBJECTIVE: We studied the cost of health care for women with breast cancer treated at the Mexican Social Security Institute (IMSS, per its abbreviation in Spanish. MATERIAL AND METHODS: Using the Medical and Operative Information Systems of the IMSS, we constructed a cohort of patients diagnosed in 2002 and followed these patients to the end of 2006, identifying the use of resources and imputing the IMSS-specific cost structure. RESULTS: Only 14% of women were diagnosed in stage 1 and 48% were diagnosed in stages III-IV. The average cost of their medical care per patient-year was $MX110,459. Costs for stage 1 were $MX74,522 compared to $102,042 for stage II, and were $MX154,018 for stage III and $MX199,274 for stage IV. CONCLUSIONS: Breast cancer accounts for a significant part of the IMSS health budget. Later stage at diagnosis is associated with higher economic costs per patient-year of treatment and lower probability of five-year survival.

    Most previous studies have linked cancer–macrophage fusion with tumor progression and metastasis. However, the characteristics of hybrid cells derived from oral cancer and endothelial cells and their involvement in cancer remained unknown. Double-immunofluorescent staining and fluorescent in situ hybridization (FISH) were performed to confirm spontaneous cell fusion between eGFP-labeled human umbilical vein endothelial cells (HUVECs) and RFP-labeled SCC9, and to detect the expression of vementin and cytokeratin 18 in the hybrids. The property of chemo-resistance of such hybrids was examined by TUNEL assay. The hybrid cells in xenografted tumor were identified by FISH and GFP/RFP dual-immunofluoresence staining. We showed that SCC9 cells spontaneously fused with cocultured endothelial cells, and the resultant hybrid cells maintained the division and proliferation activity after re-plating and thawing. Such hybrids expressed markers of both parental cells and became more resistant to chemotherapeutic drug cisplatin as compared to the parental SCC9 cells. Our in vivo data indicated that the hybrid cells contributed to tumor composition by using of immunostaining and FISH analysis, even though the hybrid cells and SCC9 cells were mixed with 1:10,000, according to the FACS data. Our study suggested that the fusion events between oral cancer and endothelial cells undergo nuclear fusion and acquire a new property of drug resistance and consequently enhanced survival potential. These experimental findings provide further supportive evidence for the theory that cell fusion is involved in cancer progression. - Highlights: • The fusion events between oral cancer and endothelial cells undergo nuclear fusion. • The resulting hybrid cells acquire a new property of drug resistance. • The resulting hybrid cells express the markers of both parental cells (i.e. vimentin and cytokeratin 18). • The hybrid cells contribute to tumor repopulation in vivo.

    NIR fluorescence imaging using indocyanine green (ICG) has the potential to improve the SLN procedure by facilitating percutaneous and intraoperative identification of lymphatic channels and SLNs. Previous studies suggested that a dose of 0.62 mg (1.6 ml of 0.5 mM) ICG is optimal for SLN mapping in breast cancer. The aim of this study was to evaluate the diagnostic accuracy of near-infrared (NIR) fluorescence for sentinel lymph node (SLN) mapping in breast cancer patients when used in conjunction with conventional techniques. Study subjects were 95 breast cancer patients planning to undergo SLN procedure at either the Dana-Farber/Harvard Cancer Center (Boston, MA, USA) or the Leiden University Medical Center (Leiden, the Netherlands) between July 2010 and January 2013. Subjects underwent the standard-of-care SLN procedure at each institution using 99Technetium-colloid in all subjects and patent blue in 27 (28%) of the subjects. NIR fluorescence-guided SLN detection was performed using the Mini-FLARE imaging system. SLN identification was successful in 94 of 95 subjects (99%) using NIR fluorescence imaging or a combination of both NIR fluorescence imaging and radioactive guidance. In 2 of 95 subjects, radioactive guidance was necessary for initial in vivo identification of SLNs. In 1 of 95 subjects, NIR fluorescence was necessary for initial in vivo identification of SLNs. A total of 177 SLNs (mean = 1.9, range = 1–5) were resected: 100% NIR fluorescent, 88% radioactive, and 78% (of 40 nodes) blue. In 2 of 95 subjects (2.1%), SLNs containing macrometastases were found only by NIR fluorescence, and in 1 patient this led to upstaging to N1. This study demonstrates the safe and accurate application of NIR fluorescence imaging for the identification of SLNs in breast cancer patients, but calls into question what technique should be used as the gold standard in future studies.

    Mexican Americans are one of the largest and fastest growing ethnic groups in the United States, yet we have limited knowledge regarding changes (i.e., developmental trajectories) in cultural orientation based upon their exposure to the Mexican American and mainstream cultures. We examined the parallel trajectories of Mexican American and mainstream cultural values in a sample of 749 Mexican American adolescents (49 % female) across assessments during the fifth grade (approximately 11 years of age), the seventh grade (approximately 13 years of age) and the tenth grade (approximately 16 years of age). We expected that these values would change over this developmental period and this longitudinal approach is more appropriate than the often used median split classification to identify distinct types of acculturation. We found four distinct acculturation trajectory groups: two trajectory groups that were increasing slightly with age in the endorsement of mainstream cultural values, one of which was relatively stable in Mexican American cultural values while the other was declining in their endorsement of these values; and two trajectory groups that were declining substantially with age in their endorsement of mainstream cultural values, one of which was also declining in Mexican American cultural values and the other which was stable in these values. These four trajectory groups differed in expected ways on a number of theoretically related cultural variables, but were not highly consistent with the median split classifications. The findings highlight the need to utilize longitudinal data to examine the developmental changes of Mexican American individual's adaptation to the ethnic and mainstream culture in order to understand more fully the processes of acculturation and enculturation.

  14. Habaneros and shwarma: Jewish Mexicans in Israel as a transnational community

    Full Text Available Food is the cultural expression of society food as a marker of class, ethnic, and religious identity. What happens when the location changes? Does food continue to play such an important role or do other cultural nodes take over? Do layers of traditions, adaptation and cultural blends emerge? This seems to be the case with third and fourth generation Mexican Jews who have moved to Israel. Not only have they brought their spiritual and cultural connections from Mexico, their birth country; they have also brought the food experiences of their great-grandparents and grandparents who were they themselves immigrants. Jewish Mexicans have transplanted their sense of community to Israel and in doing so they have also brought overlooked cultural interactions and unique food experiences. Are these simply by-products of religious and migration patterns? Or are there other elements that have affected this cultural hybridity?

    Full Text Available This paper describes a study investigating the provider-patient communication perceptions, experiences, needs and strategies of doctors and nurses working together in a UK cancer setting. This was a qualitative study using individual interviews and focus group discussions. Interpretative Phenomenological analysis (IPA was used to underpin data collection and analysis. Twenty-six staff participated in the project (18 nurses and 8 doctors. Both professional groups identified an inherent emotional strain in their daily interactions with patients. The strategies they adopted to reduce this strain fell into two main categories: 1 Handling or managing the patient to keep negative emotion at bay; and 2 Managing self to keep negative emotion at bay. These strategies allowed staff to maintain a sense of control in an emotionally-stressful environment. Most believed that their communication skills were sufficient. In conclusion, communicating with and caring for cancer patients causes considerable psycho-social burden for doctors and nurses. Managing this burden influences their communication with patients. Without recognition of the need for staff to protect their own emotional well-being, communication skills training programmes, emphasised in current UK cancer care guidelines, may have little impact on practice.

    This study aimed review studies conducted on Mexican patients diagnosed with gastric cancer and/or diseases associated with its development, in which at least one Mexican institute has participated, and to assess their contributions to the primary and secondary prevention of this disease. A search of the Medline database was conducted using the following keywords: gastric/stomach cancer, Mexico. Studies of the Mexican population were selected in which at least one Mexican Institute had participated and where the findings could support public policy proposals directed towards the primary or secondary prevention of gastric cancer. Of the 148 studies found in the Medline database, 100 were discarded and 48 were reviewed. According to the analysis presented, these studies were classified as: epidemiology of gastric cancer (5/48); risk factors and protectors relating to gastric cancer (9/48); relationship between Helicobacter pylori and pathologies associated with gastric cancer and the development of the disease (16/48); relationship between the Epstein-Barr virus and pathologies associated with gastric cancer and the development of the disease (3/48); molecular markers for the development of diseases associated with gastric cancer and gastric cancer (15/48). Mexico requires a program for the prevention and control of gastric cancer based on national health indicators. This should be produced by a multidisciplinary committee of experts who can propose actions that are relevant in the current national context. The few studies of gastric cancer conducted on the Mexican population in national institutes highlight the poor connection that currently exists between the scientific community and the health sector in terms of resolving this health issue. Public policies for health research should support projects with findings that can be translated into benefits for the population.

    INTRODUCTION The availability of monoclonal antibodies in Cuba has facilitated development and application of innovative techniques (immunoscintigraphy and radioimmunotherapy) for cancer diagnosis and treatment. Objective Review immunoscintigraphy and radioimmunotherapy techniques and analyze their use in Cuba, based on the published literature. In this context, we describe the experience of Havana's Clinical Research Center with labeled monoclonal antibodies for cancer diagnosis and treatment during the period 1993-2013. EVIDENCE ACQUISITION Basic concepts concerning cancer and monoclonal antibodies were reviewed, as well as relevant international and Cuban data. Forty-nine documents were reviewed, among them 2 textbooks, 34 articles by Cuban authors and 13 by international authors. All works published by the Clinical Research Center from 1993 through 2013 were included. Bibliography was obtained from the library of the Clinical Research Center and Infomed, Cuba's national health telematics network, using the following keywords: monoclonal antibodies, immunoscintigraphy and radioimmunotherapy. RESULTS Labeling the antibodies (ior t3, ior t1, ior cea 1, ior egf/r3, ior c5, h-R3, 14F7 and rituximab) with radioactive isotopes was a basic line of research in Cuba and has fostered their use as diagnostic and therapeutic tools. The studies conducted demonstrated the good sensitivity and diagnostic precision of immunoscintigraphy for detecting various types of tumors (head and neck, ovarian, colon, breast, lymphoma, brain). Obtaining different radioimmune conjugates with radioactive isotopes such as 99mTc and 188Re made it possible to administer radioimmunotherapy to patients with several types of cancer (brain, lymphoma, breast). The objective of 60% of the clinical trials was to determine pharmacokinetics, internal dosimetry and adverse effects of monoclonal antibodies, as well as tumor response; there were few adverse effects, no damage to vital organs, and a positive

    Most women do not reconstruct their breast(s) post-mastectomy. The experiences of younger women who maintain this decision, although important to understand, are largely absent in the research literature. This interview-based study uses interpretative phenomenological analysis to explore the experiences of six women, diagnosed with primary breast cancer in their 30s/40s, who decided against delayed reconstruction. Findings reported here focus on one superordinate theme (decision-making) from a larger analysis, illustrating that the women's drive to survive clearly influenced their initial decision-making process. Their tenacity in maintaining their decision is highlighted, despite non-reconstruction sometimes being presented negatively by medical teams. Patient-centred support recommendations are made.

    There is currently very little research on how physicians respond to patients with cancer who decide to forgo or stop medically recommended "curative" therapy. The purpose of this article is to report on a qualitative study with 12 oncology specialists in Israel and Australia that addresses this question. The findings indicate that physicians tend to construct patients and their decisions in terms of mutually exclusive categories that focus on curability of the disease, rationality of the patient's decision, and patients' personal attributes. Physicians' constructions of their experience focus on uncertainty and concern. Although contextual factors play a role in how physicians act in this situation, Israeli and Australian oncologists are remarkably similar in how they describe their own and their patients' experiences.

    Low-income Mexican American women experience significant health disparities during the postpartum period. Contextual stressors, such as economic stress, are theorized to affect health via dysregulated cortisol output. However, cultural protective factors including strong family support may buffer the impact of stress. In a sample of 322 low-income Mexican American women (mother age 18-42; 82% Spanish-speaking; modal family income $10,000-$15,000), we examined the interactive influence of economic stress and family support at 6 weeks postpartum on maternal cortisol output (AUCg) during a mildly challenging mother-infant interaction task at 12 weeks postpartum, controlling for 6-week maternal cortisol and depressive symptoms. The interaction significantly predicted cortisol output such that higher economic stress predicted higher cortisol only among women reporting low family support. These results suggest that family support is an important protective resource for postpartum Mexican American women experiencing elevated economic stress.

    2007-05-01

    In this descriptive study we employ episodic narrative interviews and narrative analysis to explore experiences of abuse and violence within the families of origin of Mexican women entering adulthood. Twenty-four Mexican women, 18 years of age and about to graduate from a residential school in central Mexico, were interviewed about life in their families of origin. Participants were from several Mexican states and of low socioeconomic status. Nineteen of the participants described either witnessing or experiencing violence or abuse within their families. We present an analysis of the interviews in which violence or abuse was disclosed. Women who witnessed violence against their mothers did not see this as prescriptive of their own future relationships and articulated strategies for avoiding entering an abusive relationship. Women who experienced nonsexual physical violence described physical violence as punishment. Women who experienced sexual abuse did not provide explanations for the abuse and described being silent in response to the abuse.

  9. Childhood asthma, air quality, and social suffering among Mexican Americans in California's San Joaquin Valley: "Nobody talks to us here".

    2009-10-01

    Nearly one in five Mexican American children residing in California's San Joaquin Valley (the Valley) in 2007 had an asthma attack at some point in their life. Numerous epidemiological studies have suggested that compared with other ethnic groups and Latino subgroups residing in the United States, Mexican origin children have the lowest rates of pediatric asthma. Ethnographic research conducted in central California, however, suggests otherwise. Known for its agricultural produce, extreme poverty, and poor air quality, the Valley is a magnet for the Mexican immigrant farm worker population. We conducted an exploratory ethnographic study to examine health disparities, social suffering, and childhood asthma in the Valley. Many Valley residents believe that their children's health concerns are being ignored. Open-ended interviews uncovered a largely rural community suffering not only from the effects of childhood asthma but the inability to have their experiences taken seriously.

    Objective The aim of this study was to explore and understand women's experience with cervical cancer screening and with the referral pathways for abnormal Papanicolau (Pap) smears. Design and setting Focus group discussions were conducted with first time colposcopy clinic attendees at a tertiary hospital colposcopy clinic in Cape Town, South Africa during November 2014. A thematic analysis was conducted to identify key themes. Initial coding categories were drawn from the interview guide. Participants 27 women participated in 4 focus group discussions. Results Participants mean age was 34 years, most did not complete secondary level education and were unemployed. Negative community opinions relating to Pap smears and colposcopy referral might deter women from seeking treatment. Having a gynaecological symptom was the most commonly cited reason for having a Pap smear. Fear of having a HIV test performed at the same time as Pap smear and low encouragement from peers, were factors identified as potential access barriers. Participants commented on insufficient or lack of information from primary providers on referral to the colposcopy clinic and concerns and apprehension during waiting periods between receiving results and the colposcopy appointment were discussed. Conclusions There is a strong and urgent need to improve current knowledge about cervical cancer and Pap smears and the necessity and benefits of timely access to screening programmes, results and treatment. Strategies such as community health education programmes and mass media interventions could be employed to disseminate cervical cancer information and address negative community perceptions. Better training and support mechanisms to equip healthcare providers with the skills to convey cervical cancer information to women are needed. The use of short message service (SMS) to deliver Pap smear results and provide patients with more information should be considered to improve waiting times for results

    Transnational Organisations increasingly prioritise the need to support local research capacity in low and middle income countries in order that local priorities are addressed with due consideration of contextual issues. There remains limited evidence on the best way in which this should be done or the ways in which external agencies can support this process.We present an analysis of the learning from the INDOX Research Network, established in 2005 as a partnership between the Institute of Cancer Medicine at the University of Oxford and India's top nine comprehensive cancer centres. INDOX aims to enable Indian centres to conduct clinical research to the highest international standards; to ensure that trials are developed to address the specific needs of Indian patients by involving Indian investigators from the outset; and to provide the training to enable them to design and conduct their own studies. We report on the implementation, outputs and challenges of simultaneously trying to build capacity and deliver meaningful research output.

    2015-03-01

    In our study that explored the current end-of-life care provision for Chinese older people with advanced/terminal cancer, hope emerged as a significant aspect of coping with their condition. Drawing on data from in-depth interviews with a group of older people, their family carers and health professionals, this article explores participants' constructions of hope in terms of what they were hoping for, how their hopes helped them cope with their illness and what sociocultural resources they drew on to build and sustain these hopes. While acknowledging similarities to Western studies of hope in terminal illness, this article identifies significant divergences in terms of the impact of different sociocultural values and their implications for clinical practice in light of an unfavourable health care environment for patients with advanced cancer and a social support system sustained mainly by Chinese families. It argues that hope represents an important resource for coping with terminal illness among these patients.

    Purpose Breast cancer treatment has progressed significantly over the past 20 years. However, knowledge regarding male breast cancer (MBC) is sparse because of its rarity. This study is an investigation of the clinicopathologic features, treatments, and clinical outcomes of MBC. Materials and Methods Clinical records of 59 MBC patients diagnosed during 1995-2014 from seven institutions in Korea were reviewed retrospectively. Results Over a 20-year period, MBC patients accounted for 0.98% among total breast cancer patients, and increased every 5 years. The median age of MBC patientswas 66 years (range, 24 to 87 years). Forty-three patients (73%) complained of a palpable breast mass initially. The median symptom duration was 5 months (range, 1 to 36 months). Mastectomy was performed in 96% of the patients. The most frequent histology was infiltrating ductal carcinoma (75%). Ninety-one percent of tumors (38/43) were estrogen receptor–positive, and 28% (11/40) showed epidermal growth factor receptor 2 (HER-2) overexpression. After curative surgery, 42% of patients (19/45) received adjuvant chemotherapy; 77% (27/35) received hormone therapy. Five out of ten patients with HER-2 overexpressing tumors did not receive adjuvant anti–HER-2 therapy, while two out of four patients with HER-2 overexpressing tumors received palliative trastuzumab for recurrent and metastatic disease. Letrozole was used for one patient in the palliative setting. The median overall survival durations were 7.2 years (range, 0.6 to 17.0 years) in patients with localized disease and 2.9 years (range, 0.6 to 4.3 years) in those with recurrent or metastatic disease. Conclusion Anti–HER-2 and hormonal therapy, except tamoxifen, have been underutilized in Korean MBC patients compared to female breast cancer patients. With the development of precision medicine, active treatment with targeted agents should be applied. Further investigation of the unique pathobiology of MBC is clinically warranted

    Purpose: To analyze retrospectively the results of intraoperative radiotherapy (IORT) with or without external beam radiotherapy ({+-} EBRT) for localized pancreatic cancer in the past three decades and to analyze prognostic factors by multivariate analysis. Methods and Materials: Records for 322 patients with pancreatic cancer treated by IORT {+-} EBRT in Tohoku University Hospital between 1980 and 2009 were reviewed. One hundred ninety-two patients who had no distant organ metastases or dissemination at the time of laparotomy were enrolled in the present study. Results: Eighty-three patients underwent gross total resection (R0: 48 patients, R1: 35 patients), and 109 patients underwent only biopsy or palliative resection. Fifty-five patients underwent adjuvant EBRT, and 124 underwent adjuvant chemotherapy. The median doses of IORT and EBRT were 25 and 40 Gy, respectively. The median follow-up period was 37.5 months. At the time of the analysis, 166 patients had disease recurrence, and 35 patients had local failure. The 2-year local control (LC) and overall survival (OS) rates were 71.0% and 16.9%, respectively. Comparison of the results for each decade showed that OS was significantly improved decade by decade (2-year: 25.0% vs. 18.8% vs. 4.2%, p < 0.001). Multivariate analysis showed that degree of resection (R0-1 vs. R2, hazard ratio = 1.97, p = 0.001) and adjuvant chemotherapy (yes vs. no, hazard ratio = 1.54, p = 0.028) had significant impacts on OS. Late gastrointestinal morbidity of Common Terminology Criteria for Adverse Events version 3.0 grade 4 or 5 was observed in four patients. Conclusion: Excellent local control for pancreatic cancer with few cases of severe late toxicity was achieved by using IORT. OS of patients with pancreatic cancer treated by IORT {+-} EBRT improved significantly decade by decade.

    To identify possible predictors of pathologic complete response (pCR) of rectal cancer after preoperative concurrent chemoradiotherapy (CCRT). We conducted a retrospective review of 53 patients with rectal cancer who underwent preoperative CCRT followed by radical surgery at a single center between January 2007 and December 2012. The median radiotherapy dose to the pelvis was 54.0 Gy (range, 45.0 to 63.0 Gy). Five-fluorouracil-based chemotherapy was administered via continuous infusion with leucovorin. The pCR rate was 20.8%. The downstaging rate was 66%. In univariate analyses, poor and undifferentiated tumors (p = 0.020) and an interval of ≥7 weeks from finishing CCRT to surgery (p = 0.040) were significantly associated with pCR, while female gender (p = 0.070), initial carcinoembryonic antigen concentration of <5.0 ng/dL (p = 0.100), and clinical stage T2 (p = 0.100) were marginally significant factors. In multivariate analysis, an interval of ≥7 weeks from finishing CCRT to surgery (odds ratio, 0.139; 95% confidence interval, 0.022 to 0.877; p = 0.036) was significantly associated with pCR, while stage T2 (odds ratio, 5.363; 95% confidence interval, 0.963 to 29.877; p = 0.055) was a marginally significant risk factor. We suggest that the interval from finishing CCRT to surgery is a predictor of pCR after preoperative CCRT in patients with rectal cancer. Stage T2 cancer may also be an important predictive factor. We hope to perform a robust study by collecting data during treatment to obtain more advanced results.

    Full Text Available Aim.The purpose of this study was to examine the outcome of patients with skeletal metastases from well-differentiated thyroid carcinoma and analyse the effect of variables that influence the prognosis of this disease. Method. We retrospectively reviewed 352 patients treated and followed-up at the Charlotte Maxeke Johannesburg Academic Hospital’s thyroid cancer clinic from 1982 - 1999. Findings. Skeletal metastases were diagnosed in 24 (6.8%, 17 at presentation to the thyroid clinic, and 7 at follow-up. Patients’ ages ranged from 30 - 77 years (mean 53.9 years and the female:male ratio was 3.8:1. Based on the original pathology reports from resected tumours, 9 were papillary and 15 were follicular cancers. Twenty-three of the 24 patients underwent thyroid surgery as the initial management – total thyroidectomy in 18, subtotal thyroidectomy in 3, and lobectomy plus neck dissection in one. The diagnosis of thyroid cancer was based on lobectomy in a single subject. Radioactive iodine (RAI was used as part of the original treatment; external radiation therapy (XRT was mainly used to alleviate severe symptoms. Twenty-one patients (87.5% were treated with RAI; 11 (45.8% received radiotherapy. Seven patients died – 4 from neurological disease directly associated with bone metastases. Of the 17 surviving patients, 2 appeared to be disease-free, 8 were asymptomatic despite overt bony disease, and 7 had persistent symptoms which much improved in 5. Bone metastases were uncommon, and follicular cancer predominated in this survey. Conclusion. RAI therapy improves quality of life in most patients. There is a place for XRT.

    Web-based learning in medical education is rapidly growing. However, there are few firsthand accounts on the rationale for and development of web-based learning programs. We present the experience of clinical educators who developed an interactive online skin cancer detection and management course in a time-efficient and cost-efficient manner without any prior skills in computer programming or technical construction of web-based learning programs. We review the current state of web-based learning including its general advantages and disadvantages as well as its specific utility in dermatology. We then detail our experience in developing an interactive online skin cancer curriculum for primary care clinicians. Finally, we describe the main challenges faced and lessons learned during the process. This report may serve medical educators who possess minimal computer programming and web design skills but want to employ the many strengths of web-based learning without the huge costs associated with hiring a professional development team.

    Full Text Available Abstract Background Transitions often occur suddenly and can be traumatic to both patients with advanced disease and their families. The purpose of this study was to explore the transition experience of older rural persons with advanced cancer and their families from the perspective of palliative home care patients, bereaved family caregivers, and health care professionals. The specific aims were to: (1 describe the experience of significant transitions experienced by older rural persons who were receiving palliative home care and their families and (2 develop a substantive theory of transitions in this population. Methods Using a grounded theory approach, 27 open-ended individual audio-taped interviews were conducted with six older rural persons with advanced cancer and 10 bereaved family caregivers. Four focus group interviews were conducted with 12 palliative care health care professionals. All interviews were transcribed verbatim, coded, and analyzed using Charmaz's constructivist grounded theory approach. Results Within a rural context of isolation, lack of information and limited accessibility to services, and values of individuality and community connectedness, older rural palliative patients and their families experienced multiple complex transitions in environment, roles/relationships, activities of daily living, and physical and mental health. Transitions disrupted the lives of palliative patients and their caregivers, resulting in distress and uncertainty. Rural palliative patients and their families adapted to transitions through the processes of "Navigating Unknown Waters". This tentative theory includes processes of coming to terms with their situation, connecting, and redefining normal. Timely communication, provision of information and support networks facilitated the processes. Conclusion The emerging theory provides a foundation for future research. Significant transitions identified in this study may serve as a focus for

    Full Text Available Abstract Background There are many differences in culture, community identity, community participation, and ownership between communities in Western and Asian countries; thus, it is difficult to adopt the results of community intervention studies from Western countries. In this study, we conducted a multicity, multicomponent community intervention trial to correct breast cancer myths and promote screening mammography for women living in an urban community in Korea. Methods A 6-month, 2-city community intervention trial was conducted. In the intervention city, 480 women were surveyed at baseline and 7 months later to evaluate the effects of the intervention program. Strategies implemented in the intervention city included community outreach and clinic and pharmacy-based in-reach strategies. Results This study showed a 20.4-percentage-point decrease in myths about the link between cancer and breast size, a 19.2-percentage-point decrease in myths concerning mammography costs, and a 14.1-percentage-point increase in intention to undergo screening mammography. We also saw a 23.4-percentage-point increase in the proportion of women at the action stage of the transtheoretical model in the intervention city. In the comparison city, smaller decreases and increases were observed. Conclusions Our study showed the value of an intervention study aimed at reducing belief in breast cancer myths in an urban community in Korea. The invention also made women more likely to undergo mammography in future.

    Considerable effort has been made to improve differentiated diagnostics as well as personalized treatment for colorectal cancer patients. High-quality fresh frozen tissue is often required to investigate relevant molecular signatures in these patients. In RNA expression studies, the "RNA integrity number" is widely accepted as a reliable marker of RNA quality. Here, we investigate the feasibility of obtaining high-quality tissue from a colon cancer biobank and the impact of in vivo ischemic time and various technical and clinicopathological factors on RNA quality. Biopsies were obtained immediately following the tumor removal. The time from clamping the main arterial supply to resection and removal of the tumor was used to estimate the in vivo ischemic time. We did not observe a significant difference in RNA quality between normal tissue and tumor tissue. We observed a significant correlation between in vivo ischemic time and RNA quality in normal tissue (r = -0.24, ptime, surgical procedure, and gender have minor but significant effects on the quality of RNA from normal colon tissue but not tumor tissue. Poorly differentiated tumors are associated with lower RNA quality. Although its impact is low, it can still be considered to note in vivo ischemic time in colon cancer specimen procurement.

    Leptomeningeal disease (LMD) represents disseminated intracranial metastatic disease that requires early detection and initiation of therapy. Patients with LMD typically present with a variety of neurologic problems, including ocular disturbances. However, little is reported on LMD presenting exclusively with ocular-related disturbances in the absence of any other central nervous system (CNS) dysfunction. Our goal was to describe the workup for ocular disturbances in the setting of known cancer diagnosis. Retrospective case study utilizing prospectively collected database at a tertiary cancer care center for all patients with diagnosis of LMD between 2001 and 2009. Main outcome was descriptive analysis of ocular findings by primary or admitting service with or without formal ophthalmology exam in workup for LMD. 34 patients demonstrated ocular disturbances without any other CNS manifestations. Our findings demonstrate that 71% of ocular disturbances were detected by the primary admitting services. Formal consultation with ophthalmology resulted in the detection of the remaining cases. The most common findings were cranial nerve deficits, papilledema, and optic disc or retinal infiltration by tumor. These findings supported a further work-up for CNS disease. Therefore, it is appropriate to refer cancer patients with visual complaints or findings on exam to ophthalmology to evaluate for evidence suggestive of LMD that may support a further work-up.

    The first multidisciplinary consensus conference on colon and rectal cancer was held in December 2012, achieving a majority of consensus for diagnostic and treatment decisions using the Delphi Method. This article will give a critical appraisal of the topics discussed during the meeting and in the consensus document by well-known leaders in surgery that were involved in this multidisciplinary consensus process. Scientific evidence, experience and opinions are collected to support multidisciplinary teams (MDT) with arguments for medical decision-making in diagnosis, staging and treatment strategies for patients with colon or rectal cancer. Surgery is the cornerstone of curative treatment for colon and rectal cancer. Standardizing treatment is an effective instrument to improve outcome of multidisciplinary cancer care for patients with colon and rectal cancer. In this article, a review of the following focuses; Perioperative care, age and colorectal surgery, obstructive colorectal cancer, stenting, surgical anatomical considerations, total mesorectal excision (TME) surgery and training, surgical considerations for locally advanced rectal cancer (LARC) and local recurrent rectal cancer (LRRC), surgery in stage IV colorectal cancer, definitions of quality of surgery, transanal endoscopic microsurgery (TEM), laparoscopic colon and rectal surgery, preoperative radiotherapy and chemoradiotherapy, and how about functional outcome after surgery?

    During the past decade, three taxa of ceratopsid ornithischians have been described from Mexico. Apparently, this group experienced a regional diversification in this area. To date Mexican Ceratopsia are represented by three species, one of which is a centrosaurine and two are chasmosaurines. Here we provide a critical review on Mexican ceratopsians and formally name a new centrosaurine ceratopsid species from the Campanian Aguja Formation as Yehuecauhceratops mudei. We also discuss possible causes for the rapid endemic diversification of Mexican ceratopsians.

  8. Hard X-ray Sources for the Mexican Synchrotron Project

    2016-10-01

    One of the principal tasks for the design of the Mexican synchrotron was to define the storage ring energy. The main criteria for choosing the energy come from studying the electromagnetic spectrum that can be obtained from the synchrotron, because the energy range of the spectrum that can be obtained will determine the applications available to the users of the future light source. Since there is a public demand of hard X-rays for the experiments in the synchrotron community users from Mexico, in this work we studied the emission spectra from some hard X-ray sources which could be the best options for the parameters of the present Mexican synchrotron design. The calculations of the flux and the brightness for one Bending Magnet and four Insertion Devices are presented; specifically, for a Superconducting Bending Magnet (SBM), a Superconducting Wiggler (SCW), an In Vacuum Short Period Undulator (IV-SPU), a Superconducting Undulator (SCU) and for a Cryogenic Permanent Magnet Undulator (CPMU). Two commonly available synchrotron radiation programs were used for the computation (XOP and SRW). From the results, it can be concluded that the particle beam energy from the current design is enough to have one or more sources of hard X-rays. Furthermore, a wide range of hard X-ray region can be covered by the analyzed sources, and the choice of each type should be based on the specific characteristics of the X-ray beam to perform the experiments at the involved beamline. This work was done within the project Fomix Conacyt-Morelos ”Plan Estrategico para la construccion y operación de un Sincrotron en Morelos” (224392).

    Near-infrared (NIR) fluorescence imaging using indocyanine green (ICG) has the potential to improve the sentinel lymph node (SLN) procedure by facilitating percutaneous and intraoperative identification of lymphatic channels and SLNs. Previous studies suggested that a dose of 0.62 mg (1.6 mL of 0.5 mM) ICG is optimal for SLN mapping in breast cancer. The aim of this study was to evaluate the diagnostic accuracy of NIR fluorescence for SLN mapping in breast cancer patients when used in conjunction with conventional techniques. Study subjects were 95 breast cancer patients planning to undergo SLN procedure at either the Dana-Farber/Harvard Cancer Center (Boston, MA, USA) or the Leiden University Medical Center (Leiden, the Netherlands) between July 2010 and January 2013. Subjects underwent the standard-of-care SLN procedure at each institution using (99)Technetium-colloid in all subjects and patent blue in 27 (28 %) of the subjects. NIR fluorescence-guided SLN detection was performed using the Mini-FLARE imaging system. SLN identification was successful in 94 of 95 subjects (99 %) using NIR fluorescence imaging or a combination of both NIR fluorescence imaging and radioactive guidance. In 2 of 95 subjects, radioactive guidance was necessary for initial in vivo identification of SLNs. In 1 of 95 subjects, NIR fluorescence was necessary for initial in vivo identification of SLNs. A total of 177 SLNs (mean 1.9, range 1-5) were resected: 100 % NIR fluorescent, 88 % radioactive, and 78 % (of 40 nodes) blue. In 2 of 95 subjects (2.1 %), SLNs-containing macrometastases were found only by NIR fluorescence, and in one patient this led to upstaging to N1. This study demonstrates the safe and accurate application of NIR fluorescence imaging for the identification of SLNs in breast cancer patients, but calls into question what technique should be used as the gold standard in future studies.

    Lophocereus schottii is a Mexican cactus known as garambullo whose bark is used for the treatment of cancer, diabetes, ulcers, sores, stomach disorders and tuberculosis. The aim of this study was to evaluate the cytotoxic effect of the ethanolic extract of bark of L. Schottii. To assess these effects we established a flow of experiments in a model of BALB/c mice murine lymphoma. We value first survival of mice inoculated with 2 × 10(4) L5178Y murine lymphoma cells, orally treated with 10 mg/Kg of the extract for 10 consecutive days; the second assessment was to determine the influence of the immune system, we carry out studies of lymphoproliferation in mice with the same conditions of the previous study, only that the treatment was for 22 days before the completion cell cultures; the third study was to establish the cytotoxic effect of extract of L. schottii using different concentrations, by murine lymphoma cell cultures and splenocytes from healthy mice and finally we assessed the effect in vivo of extract of L. Schottii in a model of solid murine lymphoma inoculating 1 × 10(7) lymphoma cells in the gastrocnemius muscle observing the development of the tumor. We observed that oral treatment of 10 mg/kg of extract of L. schottii increased survival rate in treated mice; additionally, an intratumoral injection of 50 and 100 mg/kg in a solid murine lymphoma located in the gastrocnemius muscle, allowed a significantly slower tumor evolution. In vitro studies determined that extract inhibited 63% of lymphoma cell growth. With these evidences it is feasible to scientifically validate that ethanolic extract of L. schottii had an effect on L5178Y murine cells lymphoma and could have the same effect in human tumors.

    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.

    Given the worldwide trend toward the integration of children with special needs into the general school system, and the Program for Educational Modernization (1989-1994) in Mexico, Mexican educators have had to reassess the politics of special education, focusing on different service delivery models. One model, Integrated Groups, which has been functioning since the 1970s and is primarily for children with learning and language disabilities, is described. New legislation recently enacted recognizes and encourages the collaboration of general education and special education to meet the needs of all children. During the school year 1994-1995, the Secretariat of Public Education (SEP; the Mexican centralized public school system) is piloting, in Mexico City, a proposal for the integration of children into the general classroom. This new model of service delivery is designed to provide greater site-based approaches to the education of individuals with learning disabilities.

    The pharmacokinetics of oral ranitidine were studied in 24 Mexican male healthy volunteers. Subjects received a tablet containing 150 mg of ranitidine (Azantac, Glaxo de México, Mexico City) after an overnight fast and blood samples were drawn at several times for a period of 24 h. Ranitidine concentration in plasma was measured by high performance liquid chromatography and pharmacokinetic parameters were determined by non-compartmental analysis. Ranitidine plasma concentration increased with time, reaching a maximum of (mean +/- SEM) 484 +/- 34 ng/ml in 2.7 +/- 0.2 h. Plasma levels then decayed with a terminal half-life of 4.8 +/- 0.3 h. The area under the plasma concentration against time curve was 2440 +/- 126 ngh/ml. Oral ranitidine pharmacokinetic parameters in Mexicans appeared to be similar to those previously reported for Caucasians.
