Psychological Meaning of a Woman with a Hysterectomy Among Mexican Physicians and Women

The psychological meaning of women who have had a hysterectomy, and attitudes toward them, were explored in 121 Mexican gynecologists, 155 women who had undergone a hysterectomy, and 115 women who had not had a hysterectomy. The surveys were completed between January and May 2011. Both groups of women defined a woman who had had a hysterectomy using words with positive meanings (healthy, happy, reassured, and complete), as well as words with negative meanings (sad, incomplete, and irritable). However, the participants who had not had a hysterectomy defined a woman who had had a hysterectomy using more negative words and showed more negative attitudes toward such a woman with a hysterectomy than those women who had undergone a hysterectomy. Among participants who had undergone a hysterectomy, those who were premenopausal prior to the surgery and those who had undergone bilateral salpingo-oophorectomy defined a woman who had had a hysterectomy in a more negative manner and showed the most negative attitudes. The gynecologists did not use words with emotional content regarding women who had had a hysterectomy and showed more neutral attitudes toward such a woman than did both groups of women. These findings could be helpful in designing support programs for women facing a hysterectomy.     

Fatalistic Beliefs and Cervical Cancer Screening Among Mexican Women

Fatalistic beliefs about cervical cancer were studied in 464 Mexican women, and how such beliefs relate to participation in cervical cancer screening was evaluated. Rural women were less likely than urban women to have had a Pap test and more likely to believe that the illness is due to bad luck or fate. These were also the beliefs most associated with nonscreening among rural women, whereas for urban women the belief most associated with nonscreening was “there is not much I can do to prevent cervical cancer.”     

Mexican Beliefs and Attitudes Toward Hysterectomy and Gender-Role Ideology in Marriage

One hundred and sixty-one Mexican respondents completed a questionnaire that measured beliefs and attitudes toward hysterectomy and another that measured gender-role ideology in marriage (GRIMQ). The participants were divided into two groups according to the GRIMQ: “high machismo/marianismo” and “low machismo/marianismo” groups. The participants belonging to the first group showed the most negative attitudes toward hysterectomy. In this group, men showed more negative attitudes toward hysterctomy and were less likely than women to believe that hysterectomy has positive aspects. The findings are discussed in light of male dominance and female subordination that prevail in certain cultural groups of Mexico.xs     

Crystallization of CO2 ice and the absence of amorphous CO2 ice in space

Carbon dioxide (CO₂) is one of the most relevant and abundant species in astrophysical and atmospheric media. In particular, CO₂ ice is present in several solar system bodies, as well as in interstellar and circumstellar ice mantles. The amount of CO₂ in ice mantles and the presence of pure CO₂ ice are significant indicators of the temperature history of dust in protostars. It is therefore important to know if CO₂ is mixed with other molecules in the ice matrix or segregated and whether it is present in an amorphous or crystalline form. We apply a multidisciplinary approach involving IR spectroscopy in the laboratory, theoretical modeling of solid structures, and comparison with astronomical observations. We generate an unprecedented highly amorphous CO₂ ice and study its crystallization both by thermal annealing and by slow accumulation of monolayers from the gas phase under an ultrahigh vacuum. Structural changes are followed by IR spectroscopy. We also devise theoretical models to reproduce different CO₂ ice structures. We detect a preferential in-plane orientation of some vibrational modes of crystalline CO₂. We identify the IR features of amorphous CO₂ ice, and, in particular, we provide a theoretical explanation for a band at 2,328 cm⁻¹ that dominates the spectrum of the amorphous phase and disappears when the crystallization is complete. Our results allow us to rule out the presence of pure and amorphous CO₂ ice in space based on the observations available so far, supporting our current view of the evolution of CO₂ ice.

Breast cancer health promotion model for older Puerto Rican women: results of a pilot programme

This article focuses on the development of a health promotion model programme for elderly Puerto Rican women intended to minimize barriers for early detection of breast cancer and to increase women's compliance with recommended guidelines. The programme was designed based on the findings of a national sample to assess knowledge, beliefs and practices of breast cancer early detection in Puerto Rican elderly women and their perceptions of barriers associated with non-compliance. It involves the combination of educational and environmental support for actions and conditions conducive to health behaviour and consists of the following components: (i) a culture- and cohort-sensitive health education programme for elderly women on breast cancer screening and assertive strategies for client-physician relationship; (ii) training for primary-care providers on current guidelines and barriers affecting compliance among older women in Puerto Rico; and (iii) coordination of necessary support services to facilitate access to clinical breast exams and mammograms. Programme implementation considers appropriate theories for health promotion and education in the older population. Evaluation measured progress in the plan implementation by assessing immediate products and long-term impact of the programme. Results of the pilot programme revealed a slight increase in knowledge and a significant decrease (p < 0.05) in beliefs after the health education sessions. Interventions in breast cancer early detection practices showed significant changes (p < 0.05) for mammogram and clinical breast examination. Different strategies must be combined to increase older women's compliance with breast cancer screening. Health system and access barriers to preventive care must be addressed.     

Immunohistochemical evaluation of H-R3 a novel humanized monoclonal antibody that neutralizes the EGF-receptor.

The epidermal growth factor receptor (EGF-R) is an important growth regulator of epithelial cancer cells, overexpressed by several human tumors and scantly detectable in most normal tissues. The introduction of monoclonal antibodies (Mabs) and more recently engineered humanized Mabs have greatly expanded the therapeutic potential of this modality of cancer treatment. The present study was designed to compare the specificity of the murine and humanized anti-EGF-R Mabs. Biotinylated Mabs were tested in samples of fetal and adult normal and neoplastic tissues by ABC peroxidase method. All fetal tissues studied were positive for both Mabs, showing 2 different staining patterns, one homogeneous and finely granular in cytoplasm and another grosser with intense labeling in both membrane and cytoplasm. A similar recognition pattern was exhibited in adult normal tissues, where an intense reactivity was also evidenced in skin, tongue, gastrointestinal tract, renal tubules, and breast gland epithelium. In tissues from genitourinary and central nervous system, a faint staining was demonstrate, whereas those from cardiovascular and lymphoid tissues proved to be negative. These Mabs exhibited a heterogeneous and strong membrane and cytoplasm staining in neoplastic cells from lung, breast, and head and neck cancer. On the basis of these results, we conclude that the humanized (h-R3) and murine (egf/r3) anti-EGF-R Mabs show a very similar immunohistochemical pattern of recognition of fetal, adult, and neoplastic tissues. Also h-R3 Mab is a novel candidate for the development of an immunotherapeutic approach suitable for the treatment of tumors with EGF-R overexpression.
