Cardiovascular diseases risk factors during the first year of life

The pattern of change in cardiovascular risk factors, blood pressure (SBP and DBP) and plasma total cholesterol (TC), over time, their tracking and their relation to anthropometric measurements during the first year of life were investigated. Also, the effect of breast feeding on TC and the relationship of blood pressure measurements and family history of CVD risk factors were examined. One hundred five newborn term, healthy infants who were seen at a pediatric clinic in The Woodlands, Texas were followed longitudinally from 2 weeks to 1 year of age. TC, blood pressure, weight and length of the infants were measured at age 2 weeks, and again at 2, 4, 6, 9 and 12 months. In addition, family history, maternal and paternal, of CVD risk factors was obtained. Data analyses included only 40 infants who completed one year of follow up.^ At 2 weeks of age, the median value for TC was 23 mg/dl higher for females than for males. This difference disappeared as infants got older. For males, most of the increase in TC median levels, from 114 to 137 mg/dl, occurred between the ages of 2 weeks and 2 months, whereas for the female group, TC levels increased moderately, about 10 mg/dl, between 9 and 12 months of age. Tracking of TC was examined by using Spearman's correlation analysis. There were strong correlations between measurements taken as early as 2 weeks of age with later measurements. These correlations were stronger and more significant for males than for females (for males, r varied between 0.51 to 0.70, whereas for females, r varied between 0.11 to 0.70). The association of body measurements with TC is no more than modest and is closer for female infants than for male infants. Analysis, also, showed that infants who received breast milk had a TC mean value 47 mg/dl higher than that for infants who received formula milk only during the period of breast feeding and this difference disappeared by age 12 months.^ In both genders, most of the increase in blood pressure (about 10-15 mmHg in both SBP and DBP) occurred during the first 4 months of life. Most of the increase for male infants occurred during the first 2 months of life, while for females, the increase in SBP and DBP was between the age of 2 and 4 months. Neither SBP nor DBP track well during the first year of life and most of the correlations between measurements at different ages were not significant for either gender. The cross-sectional relationship of blood pressure measurements and selected body measurements was assessed. For females, only at age of 12 months did DBP have positive and significant correlations with weight, length and Quetelet index (r = 0.57, 0.60 and 0.57, respectively). There were no significant correlations between blood pressure and body measurements for males. Finally, analysis showed that maternal history of CV risk factors was significantly related to SBP in the female infant group, but not for males. For DBP, neither maternal nor paternal history was related. ^

LIFE SATISFACTION: A COMPARISON OF RETIRED AND EMPLOYED WOMEN

This research addressed the question of life satisfaction for retired and employed women with long-term employment in a typically female occupational setting. Questions of how women's retirement is related to life satisfaction have been largely neglected because of cultural assumptions about the relative unimportance of the work role in women's lives. It is generally believed that the major source of satisfaction for women is in traditional family roles. Therefore, it follows that retirement from work is not experienced as a loss for women.^ The actual consequences of women's retirement have not been examined systematically. Descriptive data about their lives are inadequate. It is not known what patterns and resources result from a lifetime of work for women.^ The objectives of the study were to test assumptions from role and continuity theory regarding life satisfaction for retired women and women employed late in life and to describe the retirement and work experiences of the women.^ Life satisfaction was measured by the Neugarten, Havighurst and Tobin Life Satisfaction Index. Perceptions of appropriate roles for females and males were assessed through an attitudinal sex-role instrument. A composite index, derived from perceptions of health, social participation, and income at two time periods, measured level of continuity. These indices and demographic information, attitudinal items about work and retirement, and social network data comprised the mailed, self-administered survey and the personal interviews.^ The study population included 91 retired and 53 employed women, 55 years or older with a minimum of 20 years continuous employment, who were enrolled in the pension program of a large retail store.^ The retired women's perceptions of their health and social participation were more positive than the employed women's. Traditional retired women demonstrated higher life satisfaction than nontraditional retired women. Both retired and employed women who perceived continuity in life patterns scored statistically higher on life satisfaction than women who perceived discontinuity. Financial planning was the area of greatest retirement concern for retired and employed women.^

Study of rural leadership and implications for community participation and development in the health and family planning programs in Bangladesh

The vast majority of Bangladesh are poor and are unable even to provide for the most basic human needs. These are the landless and marginal farmers of Bangladesh. They constitute 70% of the rural population, which in turn constitute about 90% of the country's population.^ Effective development of Bangladesh would largely mean the development of the landless and marginal farmers. Past efforts of development in this section of the population, including that of the government, have not succeeded. One of the development goals of the government of Bangladesh is to improve the quality of life of the rural population through health and population control measures. Overpopulation, malnutrition and diarrhea are the major impediments to socioeconomic development in Bangladesh.^ The current study was designed to identify whether there is effective opinion leadership among the marginal and landless peasants affecting decisions on acceptance or nonacceptance of family planning methods and oral rehydration therapy (ORT) in the selected rural areas of Bangladesh. The study was conducted in eight randomly selected villages with funding from the Ministry of Health and Family Planning, government of Bangladesh. One hundred twenty-five opinion leaders were interviewed after they were identified by 408 rural couples owning land less than 2 acres and wives' age below 50. The study was conducted in two phases; couples' interview preceded that of the leaders.^ Findings of the study reveal that the opinion leaders influencing adoption of health and family planning among the landless and marginal farmers belong to the same class. Theses opinion leaders own land much less than the rich farmers and the formal leaders in the rural areas. Majority of these of opinion leaders are friends, neighbors and relatives, some are other persons who are businessmen and professionals like doctors, while the rest few are the field workers of health and family planning. Source of influence as a factor contribute most in differentiating use and non-use of family planning and ORT among both couples and leaders. The most frequent sources of influence referred by the couples and the leaders are the field workers of health and family planning, followed by the peer opinion leaders (friends, neighbors, relatives) and spouse.^ The opinion leaders do not differ much from the poor couples on land holding, a strong indicator of economic status, they however differ considerably on social factors such as family planning practice, education, and exposure to mass media.^ The study suggests that future development efforts in Bangladesh have to ensure community participation by the landless and marginal farmers and opinion leaders belonging to their class. ^

Engaging stakeholders in community-level obesity prevention programming: Evaluation of the Fit Family Challenge

Introduction: Both a systems approach to change and a focus on multi-sector interventions ensures obesity prevention programming within the community is equitable, sustainable, and cost-effective. An authentic community engagement approach is required to implement interventions guided by best-evidence research and practice. Although there are examples illustrating the benefits of community engagement, there is no standardized method to implement it. The San Antonio Sports Foundation (SA Sports), a non-profit community-based organization, implements a variety of free events and programs promoting active life styles. One such program is the Fit Family Challenge which is a summer-long program implemented at the school level targeted at families. ^ Aims: This thesis was a culmination of the experience from the student collaborating with SA Sports as part of a practicum opportunity. Using secondary data collected by the Fit Family Challenge during the 2011 year, the goals of this thesis were: to assess individual changes; evaluate short-term impact; and describe the community engagement process. ^ Methods: SA Sports collected quantitative and qualitative data during the implementation and evaluation of the FFC program. SA Sports allowed the used of de-identified data to be analyzed to study the aims of this thesis. ^ Results: The program was able to provide families with the knowledge, information, and opportunity to exercise as a family and cook healthier meals. School district coordinators were generally satisfied and illustrated the benefits of a community partnership. An authentic community engagement was present highlighting the importance of communication, collaboration and the sustainability of such partnerships in the community. ^ Conclusion: The success of an obesity program should focus on triggers that initiate behavioral change rather than physiological changes. The evaluation was guided by a community engagement approach, which illustrated the development of new partnerships and the strengthening of other collaborations. Ultimately, the engagement approach empowered the community to identify their own problems and build collaboration, rather than tackling obesity prevention alone. ^

Intensive care unit utilization among patients with cancer at the end of life

Over the last 2 decades, survival rates in critically ill cancer patients have improved. Despite the increase in survival, the intensive care unit (ICU) continues to be a location where end-of-life care takes place. More than 20% of deaths in the United States occur after admission to an ICU, and as baby boomers reach the seventh and eighth decades of their lives, the volume of patients in the ICU is predicted to rise. The aim of this study was to evaluate intensive care unit utilization among patients with cancer who were at the end of life. End of life was defined using decedent and high-risk cohort study designs. The decedent study evaluated characteristics and ICU utilization during the terminal hospital stay among patients who died at The University of Texas MD Anderson Cancer Center during 2003-2007. The high-risk cohort study evaluated characteristics and ICU utilization during the index hospital stay among patients admitted to MD Anderson during 2003-2007 with a high risk of in-hospital mortality. Factors associated with higher ICU utilization in the decedent study included non-local residence, hematologic and non-metastatic solid tumor malignancies, malignancy diagnosed within 2 months, and elective admission to surgical or pediatric services. Having a palliative care consultation on admission was associated with dying in the hospital without ICU services. In the cohort of patients with high risk of in-hospital mortality, patients who went to the ICU were more likely to be younger, male, with newly diagnosed non-metastatic solid tumor or hematologic malignancy, and admitted from the emergency center to one of the surgical services. A palliative care consultation on admission was associated with a decreased likelihood of having an ICU stay. There were no differences in ethnicity, marital status, comorbidities, or insurance status between patients who did and did not utilize ICU services. Inpatient mortality probability models developed for the general population are inadequate in predicting in-hospital mortality for patients with cancer. The following characteristics that differed between the decedent study and high-risk cohort study can be considered in future research to predict risk of in-hospital mortality for patients with cancer: ethnicity, type and stage of malignancy, time since diagnosis, and having advance directives. Identifying those at risk can precipitate discussions in advance to ensure care remains appropriate and in accordance with the wishes of the patient and family.^

End -of -life planning and decision -making: Implications for adults with mental retardation

This research focused on the topic of end-of-life planning and decision-making for adults affected by mental retardation. Adults with mental retardation have unique challenges in this regard, including difficulty communicating their wishes without assistance and diminished decision-making skills. The primary research objective was to identify factors that can affect opportunities for adults with mental retardation in community-based services settings (and their advocates) to be involved in planning and deciding about their own end-of-life experience. ^ A descriptive qualitative inquiry was designed to explore issues related to death and dying, and the notion of end-of-life planning, from the perspective of adults with mental retardation who receive publicly-funded community services ("clients") and family members of individuals who receive such services. Study participants were recruited from a single mental retardation service provider in a large urban setting (the "Agency"). Sixteen clients and 14 families of Agency clients took part. Client data collection was accomplished through face-to-face interviews, focus group meetings, and record reviews; family members were involved in a face-to-face interview only. ^ An initial coding scheme was developed based upon literature and policy reviews, and themes related to the research questions. Analysis involved extracting data from transcripts and records and placing it into appropriate thematic categories, building support for each theme with the accumulated data. Coding themes were modified to accommodate new data when it challenged existing themes. ^ Findings suggest that adults with mental retardation do have the requisite knowledge, interest, and ability to participate in decisions about their end-of-life experience and handling of affairs. Siblings are overwhelmingly the chosen future surrogates and they (or their children) will likely be the end-of-life advocates for their brothers and sisters affected by mental retardation. Findings further point to a need for increased awareness, accurate information, and improved communication about end-of-life issues, both in general and particular to adults affected by mental retardation. Also suggested by the findings is a need to focus on creating accommodations and adaptations that can best uncover a person's authentic views on life and death and related end-of-life preferences. Practical implications and suggestions for further research are also discussed. ^

RacF1, a Novel Member of the Rho Protein Family in Dictyostelium discoideum, Associates Transiently with Cell Contact Areas, Macropinosomes, and Phagosomes

Using a PCR approach we have isolated racF1, a novel member of the Rho family in Dictyostelium. The racF1 gene encodes a protein of 193 amino acids and is constitutively expressed throughout the Dictyostelium life cycle. Highest identity (94%) was found to a RacF2 isoform, to Dictyostelium Rac1A, Rac1B, and Rac1C (70%), and to Rac proteins of animal species (64–69%). To investigate the role of RacF1 in cytoskeleton-dependent processes, we have fused it at its amino-terminus with green fluorescent protein (GFP) and studied the dynamics of subcellular redistribution using a confocal laser scanning microscope and a double-view microscope system. GFP–RacF1 was homogeneously distributed in the cytosol and accumulated at the plasma membrane, especially at regions of transient intercellular contacts. GFP–RacF1 also localized transiently to macropinosomes and phagocytic cups and was gradually released within <1 min after formation of the endocytic vesicle or the phagosome, respectively. On stimulation with cAMP, no enrichment of GFP–RacF1 was observed in leading fronts, from which it was found to be initially excluded. Cell lines were obtained using homologous recombination that expressed a truncated racF1 gene lacking sequences encoding the carboxyl-terminal region responsible for membrane targeting. These cells displayed normal phagocytosis, endocytosis, and exocytosis rates. Our results suggest that RacF1 associates with dynamic structures that are formed during pinocytosis and phagocytosis. Although RacF1 appears not to be essential, it might act in concert and/or share functions with other members of the Rho family in the regulation of a subset of cytoskeletal rearrangements that are required for these processes.

Mutations in HYAL1, a member of a tandemly distributed multigene family encoding disparate hyaluronidase activities, cause a newly described lysosomal disorder, mucopolysaccharidosis IX

Hyaluronan (HA), a large glycosaminoglycan abundant in the extracellular matrix, is important in cell migration during embryonic development, cellular proliferation, and differentiation and has a structural role in connective tissues. The turnover of HA requires endoglycosidic breakdown by lysosomal hyaluronidase, and a congenital deficiency of hyaluronidase has been thought to be incompatible with life. However, a patient with a deficiency of serum hyaluronidase, now designated as mucopolysaccharidosis IX, was recently described. This patient had a surprisingly mild clinical phenotype, including notable periarticular soft tissue masses, mild short stature, an absence of neurological or visceral involvement, and histological and ultrastructural evidence of a lysosomal storage disease. To determine the molecular basis of mucopolysaccharidosis IX, we analyzed two candidate genes tandemly distributed on human chromosome 3p21.3 and encoding proteins with homology to a sperm protein with hyaluronidase activity. These genes, HYAL1 and HYAL2, encode two distinct lysosomal hyaluronidases with different substrate specificities. We identified two mutations in the HYAL1 alleles of the patient, a 1412G → A mutation that introduces a nonconservative amino acid substitution (Glu268Lys) in a putative active site residue and a complex intragenic rearrangement, 1361del37ins14, that results in a premature termination codon. We further show that these two hyaluronidase genes, as well as a third recently discovered adjacent hyaluronidase gene, HYAL3, have markedly different tissue expression patterns, consistent with differing roles in HA metabolism. These data provide an explanation for the unexpectedly mild phenotype in mucopolysaccharidosis IX and predict the existence of other hyaluronidase deficiency disorders.

Delayed symptom onset and increased life expectancy in Sandhoff disease mice treated with N-butyldeoxynojirimycin

Sandhoff disease is a neurodegenerative disorder resulting from the autosomal recessive inheritance of mutations in the HEXB gene, which encodes the β-subunit of β-hexosaminidase. GM2 ganglioside fails to be degraded and accumulates within lysosomes in cells of the periphery and the central nervous system (CNS). There are currently no therapies for the glycosphingolipid lysosomal storage diseases that involve CNS pathology, including the GM2 gangliosidoses. One strategy for treating this and related diseases is substrate deprivation. This would utilize an inhibitor of glycosphingolipid biosynthesis to balance synthesis with the impaired rate of catabolism, thus preventing storage. One such inhibitor is N-butyldeoxynojirimycin, which currently is in clinical trials for the potential treatment of type 1 Gaucher disease, a related disease that involves glycosphingolipid storage in peripheral tissues, but not in the CNS. In this study, we have evaluated whether this drug also could be applied to the treatment of diseases with CNS storage and pathology. We therefore have treated a mouse model of Sandhoff disease with the inhibitor N-butyldeoxynojirimycin. The treated mice have delayed symptom onset, reduced storage in the brain and peripheral tissues, and increased life expectancy. Substrate deprivation therefore offers a potentially general therapy for this family of lysosomal storage diseases, including those with CNS disease.

Mammalian Scratch: A neural-specific Snail family transcriptional repressor

Members of the Snail family of zinc finger transcription factors are known to play critical roles in neurogenesis in invertebrates, but none of these factors has been linked to vertebrate neuronal differentiation. We report the isolation of a gene encoding a mammalian Snail family member that is restricted to the nervous system. Human and murine Scratch (Scrt) share 81% and 69% identity to Drosophila Scrt and the Caenorhabditis elegans neuronal antiapoptotic protein, CES-1, respectively, across the five zinc finger domain. Expression of mammalian Scrt is predominantly confined to the brain and spinal cord, appearing in newly differentiating, postmitotic neurons and persisting into postnatal life. Additional expression is seen in the retina and, significantly, in neuroendocrine (NE) cells of the lung. In a parallel fashion, we detect hScrt expression in lung cancers with NE features, especially small cell lung cancer. hScrt shares the capacity of other Snail family members to bind to E-box enhancer motifs, which are targets of basic helix–loop–helix (bHLH) transcription factors. We show that hScrt directly antagonizes the function of heterodimers of the proneural bHLH protein achaete-scute homolog-1 and E12, leading to active transcriptional repression at E-box motifs. Thus, Scrt has the potential to function in newly differentiating, postmitotic neurons and in cancers with NE features by modulating the action of bHLH transcription factors critical for neuronal differentiation.

Root of the universal tree of life based on ancient aminoacyl-tRNA synthetase gene duplications.

Universal trees based on sequences of single gene homologs cannot be rooted. Iwabe et al. [Iwabe, N., Kuma, K.-I., Hasegawa, M., Osawa, S. & Miyata, T. (1989) Proc. Natl. Acad. Sci. USA 86, 9355-9359] circumvented this problem by using ancient gene duplications that predated the last common ancestor of all living things. Their separate, reciprocally rooted gene trees for elongation factors and ATPase subunits showed Bacteria (eubacteria) as branching first from the universal tree with Archaea (archaebacteria) and Eucarya (eukaryotes) as sister groups. Given its topical importance to evolutionary biology and concerns about the appropriateness of the ATPase data set, an evaluation of the universal tree root using other ancient gene duplications is essential. In this study, we derive a rooting for the universal tree using aminoacyl-tRNA synthetase genes, an extensive multigene family whose divergence likely preceded that of prokaryotes and eukaryotes. An approximately 1600-bp conserved region was sequenced from the isoleucyl-tRNA synthetases of several species representing deep evolutionary branches of eukaryotes (Nosema locustae), Bacteria (Aquifex pyrophilus and Thermotoga maritima) and Archaea (Pyrococcus furiosus and Sulfolobus acidocaldarius). In addition, a new valyl-tRNA synthetase was characterized from the protist Trichomonas vaginalis. Different phylogenetic methods were used to generate trees of isoleucyl-tRNA synthetases rooted by valyl- and leucyl-tRNA synthetases. All isoleucyl-tRNA synthetase trees showed Archaea and Eucarya as sister groups, providing strong confirmation for the universal tree rooting reported by Iwabe et al. As well, there was strong support for the monophyly (sensu Hennig) of Archaea. The valyl-tRNA synthetase gene from Tr. vaginalis clustered with other eukaryotic ValRS genes, which may have been transferred from the mitochondrial genome to the nuclear genome, suggesting that this amitochondrial trichomonad once harbored an endosymbiotic bacterium.

Latino Family Involvement: An Exploratory Study of Latina Mother-Daughter Relationships and their Effects on Educational Attainment and Resiliency

Latino family involvement is an important issue in the field of education. Effective strategies to promote family involvement in the Latino community are vital for the educational attainment of Latino students and emotional wellbeing of Latino families. This study used focus groups, in-depth interviews, and observations to examine Latino family involvement and the relationships and communication patterns between Latina mothers and daughters. The Latina mother-daughter relationship was studied in an effort to gain a better understanding of how this relationship affects a Latina daughter's educational attainment and sense of resiliency. Results indicated that a positive relationship between a Latina mother and daughter can increase a Latina daughter's level of educational attainment and sense of resiliency. Additionally, a Latina daughter's level of self-motivation can affect her level of educational attainment as well. Cultural narratives were found to be a common type of communication pattern used between Latina mothers and daughters. They were used to teach cultural values, life lessons, and experiential learning. By improving family involvement efforts within the Latino culture, Latino students will likely see drastic improvements in their overall levels of educational attainment and emotional wellbeing in schools. Implications for Latino students and families, schools that work with Latino families, and educational policy are also discussed.

The First Child In A Chinese Family Who Could Read Prior To Entry Into Elementary School: A Qualitative Intrinsic Case Study

ABSTRACT This study is an account of the literacy-related human environment a Chinese girl experienced as the first person in the history of her family who was able to read prior to entry into elementary school. Temporally speaking, the study spanned more than a decade from the initial, tentative research question to the formal, primary research question. Spatially speaking, it crossed three cultures: the Chinese, Korean, and American cultures. The study was inspired by the Zero Project in China, known as the "Project of Quality Education and Implementation for Children Aged Zero (fetus) to Six." The significance of the content issue in a child's literacy curriculum was explored in an interdisciplinary way. Case study served as a holistic research approach and provided the researcher with free temporal and spatial distance to pursue the indefinably multi-dimensional intricacies of a child's early literacy acquisition among generations in the family. Interpretation of the case was based on the relevant concepts within the scope of the researcher's knowledge of Chinese culture. Major findings revealed that the child's literacy acquisition was inseparably related to her parents' background as well as their awareness of and attitudes towards literacy, and that the foundation of all this was the harmony of the family. Through the lens of generational attitudes towards literacy and especially the lens of the researcher's multicultural life experiences, this study contributes to the field of curriculum studies in general and early literacy curriculum in particular by stimulating people to reconsider what to read to children, besides how to read to them. It calls attention once again to the classic curriculum question, "What knowledge is of most worth?" as well as what is the most essential spiritual food human beings need besides physical needs. This study suggests that Chinese philosophy should be included in a child's early literacy curriculum in China and calls for dialogues on the content issue of curriculum to gain a deeper understanding of human nature so that humans might co-live peacefully with all beings in the universe.

Examining the University of Denver's Family Friendly Benefits Plans: A look at Creating More Family Friendly Benefits to Drive Employee Retention

In the latter half of the twentieth century the workforce dynamic changed when the number of women entering the workforce increased by record amounts. In direct opposition to this change was the inability of organizations to meet the needs of employees with childcare concerns. Organizations and employees alike are best served when policies, procedures, and benefits are implemented to achieve a positive work/life balance. Companies that institute benefits that are supportive to families observe decreases in turnover and increased employee retention. Employees who are offered family friendly resources have been known to stay with companies even when offered a higher salary elsewhere. Demonstrating that retention of valued employees is linked to an organizations ability to offer support for family needs.

Late life second move housing choices of international retiree migrants

Purpose – Many international retirement migrants are amenity movers undertaking the first move in the late life course model of migration. The purpose of this paper is to examine second moves within the retirement destination community to test whether the model of late life course migration accurately portrays the motivations and housing choices local movers make after retiring to another country. Design/methodology/approach – The paper combines secondary data and survey results to examine the composition of the retiree migrant population in the Alicante province of Spain. The socioeconomic characteristics and housing choices of those who have made a second move since retiring to Spain are compared with those who have not moved through a series of t-tests and chi-square tests. Findings – The paper finds that those who have made a second move within Spain are somewhat typical of second movers in the late life course. They are likely to cite mobility or health problems as a reason for moving and appear to recognize the need for a home that provides living area on one floor. Yet, they are choosing to move within an area that does not provide them with access to informal family care givers. Research limitations/implications – The data are restricted to retirees of two nationalities in one province of Spain. Further research is suggested in other locations and with retirees of other nationalities for comparison. Practical implications – Because many international retirees do not plan to return to their countries of origin, they will create demand for formal in-home care services and supportive retiree housing in the near future in their retirement destination countries. Originality/value – This paper provides understanding of a growing consumer housing segment in retirement destinations.
