THE EFFECT OF PREECLAMPSIA ON RENAL FUNCTION: CROSS-SECTIONAL STUDIES OF POSTPARTUM PREECLAMPTICS AND WOMEN WHO WERE DESTINED TO DEVELOP PREECLAMPSIA

Preeclampsia (PE) is a pregnancy complication that is new-onset of hypertension and proteinuria after 20 weeks of gestation. However, subclinical renal dysfunction may be apparent earlier in gestation prior to the clinical presentation of PE. Although the maternal syndrome of PE resolves early postpartum, women with a history of PE are at higher risk of renal dysfunction later in life. Mineral metabolism, such as phosphate balance is heavily dependent on renal function, yet, phosphate handling in women with a history of PE is largely unknown. To investigate whether women with a history of PE would exhibit changes in phosphate metabolism compared to healthy parous women, phosphate loading test was used. Women with or without a history of PE, who were 6 months to 5 years postpartum, were recruited for this study. Blood and urine samples were collected before and after the oral dosing of 500mg phosphate solution. Biochemical markers of phosphate metabolism and renal function were evaluated. In order to assess the difference in renal function alteration between first trimester women who were or were not destined to develop PE, plasma cystatin C concentration was analysed. After phosphate loading, women with a history of PE had significantly elevated serum phosphate at both 1- and 2-hour, while controls had higher urine phosphate:urine creatinine excretion ratio at 1-hour than women with a history of PE. Women with a history of PE had no changes in intact parathyroid hormone (iPTH) concentration throughout the study period, whereas controls had elevated iPTH at 1-hour from baseline. In terms of renal function in the first trimester, there was no difference in plasma cystatin C concentration between women who were or were not destined to develop PE. The elevation of serum phosphate in women with a history of PE could be due to the delay in phosphate excretion. Prolong elevation of serum phosphate can have serious consequences later in life. Thus, oral phosphate challenge may serve as a useful method of early screening for altered phosphate metabolism and renal function.

A Value Networks Approach to Implementing Integrated Cross-National Business Operations

The removal of trade impediments is expected to cause companies to integrate more of their operations among countries; however, experience shows that behavioral factors often impede the requisite cooperation and commitment among managers from different countries. This paper discusses these behavioral problems from a national perspective and examines an approach to integration, value networks, which is not bounded by nation-states and their differences or similarities.

Cancer appetite and symptom questionnaire (CASQ) for brazilian patients: Cross-cultural adaptation and validation study

Background: Appetite and symptoms, conditions generally reported by the patients with cancer, are somewhat challenging for professionals to measure directly in clinical routine (latent conditions). Therefore, specific instruments are required for this purpose. This study aimed to perform a cultural adaptation of the Cancer Appetite and Symptom Questionnaire (CASQ), into Portuguese and evaluate its psychometric properties on a sample of Brazilian cancer patients. Methods: This is a validation study with Brazilian cancer patients. The face, content, and construct (factorial and convergent) validities of the Cancer Appetite and Symptom Questionnaire, the study tool, were estimated. Further, a confirmatory factor analysis (CFA) was conducted. The ratio of chi-square and degrees of freedom (χ2/df), comparative fit index (CFI), goodness of fit index (GFI) and root mean square error of approximation (RMSEA) were used for fit model assessment. In addition, the reliability of the instrument was estimated using the composite reliability (CR) and Cronbach’s alpha coefficient (α), and the invariance of the model in independent samples was estimated by a multigroup analysis (Δχ2). Results: Participants included 1,140 cancer patients with a mean age of 53.95 (SD = 13.25) years; 61.3% were women. After the CFA of the original CASQ structure, 2 items with inadequate factor weights were removed. Four correlations between errors were included to provide adequate fit to the sample (χ2/df = 8.532, CFI = .94, GFI = .95, and RMSEA = .08). The model exhibited a low convergent validity (AVE = .32). The reliability was adequate (CR = .82 α = .82). The refined model showed strong invariance in two independent samples (Δχ2: λ: p = .855; i: p = .824; Res: p = .390). A weak stability was obtained between patients undergoing chemotherapy and radiotherapy (Δχ2: λ: p = .155; i: p < .001; Res: p < .001), and between patients undergoing chemotherapy combined with radiotherapy and palliative care (Δχ2: λ: p = .058; i: p < .001; Res: p < .001). Conclusion: The Portuguese version of the CASQ had good face and construct validity and reliability. However, the CASQ still presented invariance in independent samples of Brazilian patients with cancer. However, the tool has low convergent validity and weak invariance in samples with different treatments.

Weaknesses in the reporting of cross-sectional studies according to the STROBE statement: the case of metabolic syndrome in adults from Peru

Introduction: The inadequate reporting of cross-sectional studies, as in the case of the prevalence of metabolic syndrome, could cause problems in the synthesis of new evidence and lead to errors in the formulation of public policies. Objective: To evaluate the reporting quality of the articles regarding metabolic syndrome prevalence in Peruvian adults using the STROBE recommendations. Methods: We conducted a thorough literature search with the terms "Metabolic Syndrome", "Sindrome Metabolico" and "Peru" in MEDLINE/PubMed, LILACS, SciELO, LIPECS and BVS-Peru until December 2014. We selected those who were populationbased observational studies with randomized sampling that reported prevalence of metabolic syndrome in adults aged 18 or more of both sexes. Information was analysed through the STROBE score per item and recommendation. Results: Seventeen articles were included in this study. All articles met the recommendations related to the report of the study’s rationale, design, and provision of summary measures. The recommendations with the lowest scores were those related to the sensitivity analysis (8%, n= 1/17), participant flowchart (18%, n= 3/17), missing data analysis (24%, n= 4/17), and number of participants in each study phase (24%, n= 4/17). Conclusion: Cross-sectional studies regarding the prevalence of metabolic syndrome in peruvian adults have an inadequate reporting on the methods and results sections. We identified a clear need to improve the quality of such studies.

Migrant youth and social policy in multicultural Australia: exploring cross-cultural networking

This chapter explores the extent to which the direction of Australia’s official multicultural and civic integration policies, reflects the social attitudes and networking practices of migrant youth. The chapter pays particular attention to the Federal Government’s “Anti-Racism Strategy” announced in 2012 as part of its Multicultural Policy. On a theoretical level, direct efforts to mitigate racism have the potential to augment strategies that reaffirm pluralism and address disadvantage often associated with the migrant experience. On an empirical level, it is important to explore the extent to which such top-level discourses have actual founding in the social lives of migrant youth. Therefore this chapter presents the empirical findings of an empirical longitudinal on “Social Networks, Belonging and Active Citizenship among Migrant Youth” (Australian Research Council Linkage project 2009–2013). Migrant youth in this study pointed to a number of instances of racism, which act as significant barriers to cross-cultural networking. Analysis of the data shows, among other things, that there is a persistent tendency among migrant youth to point to their social distance from the metaphorical “Aussie Aussie” people of Anglo origins who are perceived as symbolising Australia’s mainstream. Such manifestations of racial discrimination preclude the emergence of a genuinely inclusive society that supports and nurtures cultural diversity as a significant part of the Australian national identity, as well as the stated objectives of its social policy repertoire.

Indigenous cultural studies: intersections between cultural studies and Indigenous studies

History, Power, Text collects together selected contributions on Indigenous themes published between 1996 and 2013 in the journal first known as UTS Review and now known as Cultural Studies Review. Since the journal’s inception, successive editors have sought to open up a space for new kinds of politics, new styles of writing and new modes of interdisciplinary engagement. Like the journal it draws its material from, this collection has been conceived and assembled as an exercise in institution building beyond ‘the Institution’. We call this institution, tentatively, ‘Indigenous cultural studies’ and see it as a disciplinary space that is built iteratively through events, single articles and books. We do not seek to prescribe or delimit this project but rather to give it density and energise those working in the overlapping fields represented here.

Age diversity and firm performance in an emerging economy: Implications for cross-cultural human resource management

This study tests the effect of age diversity on firm performance among international firms. Based on the resource-based view of the firm, it argues that age diversity among employees will influence firm performance. Moreover, it argues that two contextual variables—a firm's level of market diversification and its country of origin—influence the relationship between age diversity and firm performance. By testing relevant hypotheses in a major emerging economy, that is, the People's Republic of China, this study finds a significant and positive effect of age diversity and a significant interactive effect between age diversity and firm strategy on profitability. We also find a significant relationship between age diversity and firm profitability for firms from Western societies, but not for firms from East Asian societies. The paper concludes by discussing the implications of this study's findings. © 2011 Wiley Periodicals, Inc.
