Social determinants of breast cancer screening: a multilevel analysis of proximal and distal factors related to the practice of mammography.

Mammography is crucial for early breast cancer detection. In Latin America, Argentina faces a significant breast cancer burden, with varying mammography rates. The social factors influencing mammography practices remain unclear. This study aimed to identify the proximal and distal social determinants of this practice among Argentinean women using a multilevel approach. This nationwide cross-sectional study included 4,924 women aged 50-70 participating in the 2018 National Risk Factor Survey of Argentina. Two-level logistic models were used to estimate measures of association (ORs) between timely mammography practice (within the last 2 years) and selected covariates (sociodemographics, proximal environment, and distal-level variables). The intraclass correlation coefficient (ICC) and proportional change in variance (PCV) were calculated. 62.8% of women underwent timely mammography. Age (OR=0.96; 95%CI 0.94-0.97), health insurance (OR=2.22; 95%CI 1.87-2.63), education (OR=2.1; 95%CI 1.74-2.64), and income (OR=1.56; 95%CI 1.23-1.97) were associated with mammography practice. Women in non-marital (OR=0.61; 95%CI 0.52-0.72) or larger households (OR=0.61; 95%CI 0.51-0.63) were less likely to have timely mammograph; living in a larger city was positively associated (OR=1.28; 95%CI 1.12-1.46). Women in provinces with higher physician density (OR=1.06; 95%CI 1.01-1.11) and lower maternal mortality ratio (OR=0.9; 95%CI 0.87-0.96) had higher chances of timely mammography. The ICC and PCV suggested that the explored healthcare indicators largely explained the macro-contextual effect. Multilevel factors influenced mammography practices in Argentina. The results highlight disparities linked to sociodemographic characteristics and healthcare resources. Efforts to address social inequalities in breast cancer screening must consider multilevel determinants, including in healthcare settings.

Profile of per- and polyfluoroalkyl substances, source appointment, and determinants in Argentinean postpartum women

BackgroundPer- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals with potential adverse health effects. Information concerning PFAS concentrations in relation to pregnancy is scarce in South America and non-existent in Argentina. AimWe aimed to investigate an extended maternal PFAS profile herein serum concentrations in a regional and global view, source appointment, and determinants in Argentinean women. MethodsA cross-sectional study with a sampling period from 2011 to 2012 included 689 women from Ushuaia and Salta in Argentina. Serum samples collected two days postpartum were analyzed by ultra-high pressure liquid chromatography coupled to electrospray negative ionisation tandem-quadrupole mass-spectrometry. Principal Component Analysis (PCA) following absolute principal component score-multiple linear regression (APCS-MLR) was used for PFAS source appointments. Determinants of PFAS were explored through a MLR approach. A review of previous studies within the same period was conducted to compare with present levels. ResultsArgentinean PFAS concentrations were the lowest worldwide, with PFOS (0.74 ng/mL) and PFOA (0.11 ng/mL) as the dominant substances. Detection frequencies largely aligned with the compared studies, indicating the worldwide PFAS distribution considering the restrictions. The PCA revealed region-specific loading patterns of two component groups of PFAS, a mixture of replaced and legacy substances in Ushuaia and long-chain in Salta. This might relate to a mix of non-diet and diet exposure in Ushuaia and diet in Salta. Region, age, lactation, parity, household members, migration, bottled water, and freshwater fish were among the determinants of various PFAS. ConclusionThis is the first study to monitor human PFAS exposure in Argentina. Maternal PFAS concentrations were the lowest observed worldwide in the same period. Exposure contributions are suggested to be affected by restrictions and substitutions. Given the limited population-based studies and the emergence of PFAS, it is essential to conduct further monitoring of PFAS in Argentina and South America.

Argentinean Women in Noir: Challenging Religious Discourses in Claudia Piñeiro’s Catedrales (2020)

Set against the backdrop of the feminist movement known as Marea verde, which organized massive protests and demonstrations to support the passing of the Ley de Interrupción Voluntaria del Embarazo (December 2020), Piñeiro’s crime novel, Catedrales (2020), confronts the fanaticism and trauma inflicted by polarizing discourses that divide the population into ‘pro-life’ and ‘pro-choice’. The novel constitutes a staunch attack on the Catholic Church and promotes a scaffolding for a new ideology (new cathedrals) that shakes the core of Argentinean women’s sentimental education, inviting readers to reflect upon current social and political issues in Argentina and worldwide.

Efficacy of Brief Intervention for Alcohol Consumption during Pregnancy in Argentinean Women: A Randomized Controlled Trial

Introduction Although Brief Intervention (BI) has proven to reduce alcohol consumption during pregnancy in high income countries, there is no evidence from the Southern Cone of America. Thus, we conducted a study to assess BI efficacy among Argentinean pregnant women. Method and Materials We collected data on pregnant women receiving prenatal care at the public health system in Mar del Plata, Argentina. Women with less than 26 weeks of gestation (n = 486) were randomized to brief advice (BA) or BI. Three months later they were re-assessed; women with more than 26 weeks of gestation constituted a screening only control group (SC) (n = 154). Self-reported quantity and frequency of alcohol consumption, frequency of binge drinking, and related problems after three months were used as outcomes. We performed generalized estimating equations and clinical significance analyses. Also, we obtained newborn health indicators from the city’s health system database to use as objective outcomes. Women who did not participate in any of the three former conditions were randomly selected to constitute a non-screening control group (NSC) (n = 150). We compared objective outcomes among BI, BA, and NSC groups using the Wilcoxon rank test. Results In comparison with SC, BI and BA reduced alcohol consumption, without differences between the latter two. Newborns of women who received BI and BA had better health indicators compared with the NSC group. Conclusions performing either a BI or BA reduces alcohol consumption among Argentinean pregnant women and might lead to healthier newborns.

Socio-environmental exposures explaining the opposites spatial patterns of mortality due to breast and cervical cancer in Argentinean women

Background: This work aimed to characterize the spatial patterns of breast (BC) and cervix (CC) cancer mortalities in Argentina (2013-2015) and to propose a socio-environmental model explaining the observed differences. Methods: An ecological multigroup design (n=511 counties nested in 24 provinces) were carried out in Argentina. Age-standardized mortality rates (SMR) of BC and CC by county were estimated. Using the 2013-2015 average rates, a Getis-Ord analysis was performed to identify spatial clusters of high (hot spots) and low (cold spots) values of SMRs. A two-level logistic regression model was fixed to assess the relationship between the presence of hot and cold spots of each cause, accounting for the spatial variability. Finally, mixed-effects Poisson models were fitted using BC or CC SMRs as outcomes, and agricultural activity -AA- level (null/intermediate/high), urban scale (big cities/middle-sized or small cities/towns) and % households with unsatisfied basic needs (UBN) as fixed effects-covariates, including a random intercept (province as clustering variable). Interaction terms between AA and UBN levels were included. Results: Mortality spatial patterns were opposite between CC and BC. The presence of BC hot spot was significantly associated with the presence of CC cold spot. Increased risk of BC mortality was associated with a higher AA level. This effect was not independent of UBN, given that in the intermediate AA areas, UBN was inversely associated with BC mortality. Besides, lower BC mortality risk was linked to the smallest urban scales (vs. big cities). An opposite effect of the urban scale was observed for CC mortality. Significant interaction terms between AA and UBN levels were found, showing that in areas with high AA, increasing NBI was associated with higher CC SMR. Conclusions: Concomitant socio-environmental exposures linked to socioeconomic conditions, anthropic exposures and urbanization could explain the differences between BC and CC mortality spatial patterns in Argentina.

General Mental Health State Indicators in Argentinean Women During Quarantine of up to 80-Day Duration for COVID-19 Pandemic.

Introduction: Argentinean quarantine during the COVID-19 pandemic is one of the most long-lasting worldwide. We focused on the first 80-days of this quarantine on Argentinean women. Our aims were to analyze differences in general mental health state (MHS) indicators, by the (1) sites of residence with different prevalence of COVID-19 cases, and (2) quarantine duration; (3) to assess multiple relationships between each general MHS indicator and potentially affecting factors.Methods: We used a cross-sectional design with convenience successive sampling (N = 5,013). The online survey included a socio-demographic questionnaire (elaborated ad hoc) with standardized and validated self-reported questionnaires (General Health Questionnaire, Kessler Psychological Distress Scale) measuring the MHS indicators: self-perceived health, psychological discomfort, social functioning and coping, and psychological distress.Results: Worse self-perceived health and higher psychological discomfort affected significantly more women residing in sites with high prevalence of COVID-19 cases, compared to those residing in sites with intermediate prevalence, but effect sizes were small. Mean scores of all general MHS indicators were significantly worse for longer quarantine sub-periods (up to 53, 68, and 80-day duration) than for shorter sub-periods (up to seven, 13, and 25-day duration). Being a younger age, having mental disorder history, and longer quarantine durations were associated to worsening MHS, while the lack of previous suicide attempt has a protective effect.Discussion: Our findings show that a worse MHS during quarantine may not be attributed to the objective risk of contagion (measured greater or less), and under quarantine, women MHS—as indicated by group central tendency measures—got worse as time went by. This strongly suggests that special attention needs to be paid to younger women and to women with history of mental disorder. Along with physical health, mental health must be a priority for the Government during and after quarantine and the COVID-19 pandemic.

Distribution of FMR1 and FMR2 Repeats in Argentinean Patients with Primary Ovarian Insufficiency.

The premutation state of FMR1 (Fragile X Mental Retardation 1) has been associated with primary ovarian insufficiency (POI), and is the most common known genetic cause for 46,XX patients. Nevertheless, very few studies have analyzed its frequency in Latin American populations. Additionally, a relationship between alleles carrying a cryptic microdeletion in the 5’UTR of FMR2 and the onset of POI has only been studied in one population. Our aim was to analyze the incidence of FMR1 premutations and putative microdeletions in exon 1 of FMR2 in a cohort of Argentinean women with POI. We studied 133 patients and 84 controls. Fluorescent PCR was performed, and the FMR2 exon 1 was further sequenced in samples presenting less than 11 repeats. We found the frequency of FMR1 premutations to be 6.7% and 2.9% for familial and sporadic patients, respectively. Among controls, 1/84 women presented a premutation. In addition, although we did not find microdeletions in FMR2, we observed a change (T >C) adjacent to the repeats in two sisters with POI. Given the repetitive nature of the sequence involved, we could not ascertain whether this represents a single nucleotide polymorphism (SNP) or a deletion. Therefore, a relationship between FMR2 and POI could not be established for our population.

Impact of the Gender Identity Law in Argentinean transgender women

ABSTRACTBackground: In May 2012, collective efforts led to the enactment of a Gender Identity Law in Argentina. This is a particularly progressive law, based on human rights principles, as it is the first in the world to recognize a person's gender identity without any preconditions. However, studies that evaluate its impact on the transgender community (positive outcomes as well as barriers to implementation) have been scant. Thus, the following study investigated the impact of the implementation of the Argentinean Gender Identity Law on the living conditions, plus it explored stigma and discrimination (S&D) experiences of transgender women. Method: Two focus groups, with 20 transgender women, were conducted. Recordings were transcribed and a thematic analysis of the transcripts was performed according to the following categories: general perceived impact of the Law, work and education, security and civil rights, health services, and perceived differences among regions and provinces. Results: After the Law's enactment, participants mostly perceived positive changes, in general, and in particular domains such as education, health care, work, security, and civil rights. A general empowering effect on the community can be inferred. However, barriers to full implementation were identified, both internal and subjective (age, internalized stigma) and external (lack of trained professionals and public servants, reluctance to implementation in conservative provinces). Discussion: This study provides the first evaluation of the implementation and impact of the Gender Identity Law in Argentina from the point of view of transgender women. The empowering effect and the improvements achieved provide preliminary information on the importance of adopting this type of policy. Additionally, the barriers to be overcome and recommendations for the future are discussed.

Breast Cancer and Modifiable Lifestyle Factors in Argentinean Women: Addressing Missing Data in a Case-Control Study

A number of studies have evidenced the effect of modifiable lifestyle factors such as diet, breastfeeding and nutritional status on breast cancer risk. However, none have addressed the missing data problem in nutritional epidemiologic research in South America. Missing data is a frequent problem in breast cancer studies and epidemiological settings in general. Estimates of effect obtained from these studies may be biased, if no appropriate method for handling missing data is applied. We performed Multiple Imputation for missing values on covariates in a breast cancer case-control study of Córdoba (Argentina) to optimize risk estimates. Data was obtained from a breast cancer case control study from 2008 to 2015 (318 cases, 526 controls). Complete case analysis and multiple imputation using chained equations were the methods applied to estimate the effects of a Traditional dietary pattern and other recognized factors associated with breast cancer. Physical activity and socioeconomic status were imputed. Logistic regression models were performed. When complete case analysis was performed only 31% of women were considered. Although a positive association of Traditional dietary pattern and breast cancer was observed from both approaches (complete case analysis OR=1.3, 95%CI=1.0-1.7; multiple imputation OR=1.4, 95%CI=1.2-1.7), effects of other covariates, like BMI and breastfeeding, were only identified when multiple imputation was considered. A Traditional dietary pattern, BMI and breastfeeding are associated with the occurrence of breast cancer in this Argentinean population when multiple imputation is appropriately performed. Multiple Imputation is suggested in Latin America’s epidemiologic studies to optimize effect estimates in the future.

Risk of Vascular Disease in Premenopausal Women With Diabetes Mellitus

PurposeThe aims of this study were (1) to estimate the prevalence of cardiovascular disease risk factors among premenopausal and menopausal Argentinean women with and without type 2 diabetes mellitus and (2) to assess the contribution of total plaque area (TPA) to risk stratification when added to Framingham risk scores. MethodsA descriptive cross-sectional study in primary prevention in 1257 women (ages 19-84 years) from Argentina. TPA was measured by ultrasonography. Framingham sex-specific risk equations were used to predict the risk of developing cardiovascular disease, coronary heart disease, and stroke during the next 10 years. Patients were divided into diabetic (n = 293) and control groups (n = 964), and then each group was divided according to age (>40, 40–49, 50–59, and ≥60 years). FindingsNo difference was observed between diabetic and control groups in the incidence of smoking or the presence of early family cardiovascular event. Overall, diabetic patients had higher body mass index, blood pressure, and TPA versus the control group. The Framingham risk score was higher in the diabetic group in all age groups. The mean (SD) coronary heart disease scores for the diabetic group at <40, 40 to 49, 50 to 59, and ≥60 were 6% (1.7%), 19% (2.5%), 38% (2.0%), and 60% (1.5%), respectively, whereas the scores in the control group 3% (0.8%), 7% (0.9%), 17% (0.9%), and 40% (0.9%), respectively. The stroke score was also enhanced in diabetic women, independent of their age. These data indicate that diabetic women in the premenopausal age or the early years of menopause age (40-50 years) are at intermediate or higher risk of developing a cardiovascular event. ImplicationsPremenopausal diabetic women should be considered at possibly high risk of cardiovascular events compared with nondiabetic women. Direct assessment of atherosclerotic burden, such as TPA, should be used early in this population instead of relying on traditional risk scores.

The contributions of risk factor trends to cardiometabolic mortality decline in 26 industrialized countries

Cardiovascular disease mortality has declined and diabetes mortality has increased in high-income countries. We estimated the potential role of trends in population body mass index, systolic blood pressure, serum total cholesterol and smoking in cardiometabolic mortality decline in 26 industrialized countries. Mortality data were from national vital statistics. Body mass index, systolic blood pressure and serum total cholesterol were from a systematic analysis of population-based data. We estimated the associations between change in cardiometabolic mortality and changes in risk factors, adjusted for change in per-capita gross domestic product. We calculated the potential contribution of risk factor trends to mortality decline. Between 1980 and 2009, age-standardized cardiometabolic mortality declined in all 26 countries, with the annual decline between <1% in Mexico to ≈ 5% in Australia. Across the 26 countries together, risk factor trends may have accounted for ≈ 48% (men) and ≈ 40% (women) of cardiometabolic mortality decline. Risk factor trends may have accounted for >60% of decline among men and women in Finland and Switzerland, men in New Zealand and France, and women in Italy; their benefits were smallest in Mexican, Portuguese, and Japanese men and Mexican women. Risk factor trends may have slowed down mortality decline in Chilean men and women and had virtually no effect in Argentinean women. The contributions of risk factors to mortality decline seemed substantially larger among men than among women in the USA, Canada and The Netherlands. Industrialized countries have varied widely in the extent of risk factor prevention, and its likely benefits for cardiometabolic mortality.

Efficient arsenic metabolism--the AS3MT haplotype is associated with DNA methylation and expression of multiple genes around AS3MT.

Arsenic is a very potent toxicant. One major susceptibility factor for arsenic-related toxicity is the efficiency of arsenic metabolism. The efficiency, in turn, is associated with non-coding single nucleotide polymorphisms (SNPs) in the arsenic methyltransferase AS3MT on chromosome 10q24. However, the mechanism of action for these SNPs is not yet clarified. Here, we assessed the influence of genetic variation in AS3MT on DNA methylation and gene expression within 10q24, in people exposed to arsenic in drinking water. DNA was extracted from peripheral blood from women in the Argentinean Andes (N = 103) and from cord blood from new-borns in Bangladesh (N = 127). AS3MT SNPs were analyzed with Sequenom or Taqman assays. Whole genome epigenetic analysis with Infinium HumanMethylation450 BeadChip was performed on bisulphite-treated DNA. Whole genome gene expression analysis was performed with Illumina DirectHyb HumanHT-12 v4.0 on RNA from peripheral blood. Arsenic exposure was assessed by HPLC-ICPMS. In the Argentinean women, the major AS3MT haplotype, associated with more efficient arsenic metabolism, showed increased methylation of AS3MT (p = 10−6) and also differential methylation of several other genes within about 800 kilobasepairs: CNNM2 (p<10−16), NT5C2 (p<10−16), C10orf26 (p = 10−8), USMG5 (p = 10−5), TRIM8 (p = 10−4), and CALHM2 (p = 0.038) (adjusted for multiple comparisons). Similar, but weaker, associations between AS3MT haplotype and DNA methylation in 10q24 were observed in cord blood (Bangladesh). The haplotype-associated altered CpG methylation was correlated with reduced expression of AS3MT and CNNM2 (rs = −0.22 to −0.54), and with increased expression of NT5C2 and USMG5 (rs = 0.25 to 0.58). Taking other possibly influential variables into account in multivariable linear models did only to a minor extent alter the strength of the associations. In conclusion, the AS3MT haplotype status strongly predicted DNA methylation and gene expression of AS3MT as well as several genes in 10q24. This raises the possibility that several genes in this region are important for arsenic metabolism.

Preferences for mode of delivery in nulliparous Argentinean women: a qualitative study

BackgroundOver the last three decades, cesarean section (CS) rates have been rising around the world despite no associated improvement in maternal and perinatal mortality and morbidity. The role of women’s preferences for mode of delivery in contributing to the high CS rate remains controversial; however these preferences are difficult to assess, as they are influenced by culture, knowledge of risk and benefits, and personal and social factors. In this qualitative study, our objective was to understand women’s preferences and motivational factors for mode of delivery. This information will inform the development and design of an assessment aimed at understanding the role of the women’s preferences for mode of delivery.MethodsWe conducted 4 focus group discussions (FGDs) and 12 in-depth interviews with pregnant women in Buenos Aires, Argentina in 4 large non-public and public hospitals. Our sample included 29 nulliparous pregnant women aged 18–35 years old, with single pregnancies over 32 weeks of gestational age, without pregnancies resulting from assisted fertility, without known pre-existing medical illness or diseases diagnosed during pregnancy, without an indication of elective cesarean section, and who are not health professionals. FGDs and interviews followed a pre-designed guide based on the health belief model and social cognitive theory of health decisions and behaviors.ResultsMost of the women preferred vaginal delivery (VD) due to cultural, personal, and social factors. VD was viewed as normal, healthy, and a natural rite of passage from womanhood to motherhood. Pain associated with vaginal delivery was viewed positively. In contrast, women viewed CS as a medical decision and often deferred decisions to medical staff in the presence of medical indication.ConclusionsThese findings converge with quantitative and qualitative studies showing that women prefer towards VD for various cultural, personal and social reasons. Actual CS rates appear to diverge from women’s preferences and reasons are discussed.

Prevalence of human papillomavirus infection in Argentinean women attending two different hospitals prior to the implementation of the National Vaccination Program

Cervarix vaccine was included in the National Immunization Program of Argentina in 2011 but data about the local distribution of human papillomavirus (HPV) infection in women exposed to the virus are scarce. This cross-sectional study determined the prevalence and type distribution of HPV infection in unvaccinated women attending routine gynecological screening in two public hospitals located in Buenos Aires and Santa Fe, Argentina. Socio-demographic, sexual behavior, and co-factors information was obtained from all participants (Buenos Aires, n = 429; Santa Fe, n = 433). Cervicovaginal swabs were tested with an MY11/09 primer-based assay and with the CUT primer system targeting mucosal/cutaneous HPVs. Participants from Buenos Aires showed significantly higher rates of HPV infection (52.4% vs. 40.6%), of multiple infections (24.2% vs. 16.4%), and of low-risk (20.3% vs. 13.9%) and high-risk types (44.1% vs. 33.3%) than those from Santa Fe. HPV-66 (Buenos Aires: 17%) and HPV-16 (Santa Fe: 8.5%) were the most prevalent types. Novel HPV-66 putative subtype and variants were identified. Vaccine types 16 and 18 were frequent (Buenos Aires: 13.5%; Santa Fe: 10.2%) but few participants had co-infections with both (Buenos Aires: 1.4%; Santa Fe: 0.2%). A common risk factor for HPV infection was having a new sexual partner in the last year (Buenos Aires: OR 2.53, P < 0.001; Santa Fe: OR 1.85, P = 0.04). This study provides valuable baseline data for future assessment of the impact of massive vaccination in Argentina and it underlines the use of additional HPV testing strategies, such as the CUT system, for surveillance and vaccinology.

Low-level environmental cadmium exposure is associated with DNA hypomethylation in Argentinean women.

Background: Cadmium, a common food pollutant, alters DNA methylation in vitro. Epigenetic effects might therefore partly explain cadmium’s toxicity, including its carcinogenicity; however, human data on epigenetic effects are lacking.Objective: We evaluated the effects of dietary cadmium exposure on DNA methylation, considering other environmental exposures, genetic predisposition, and gene expression.Methods: Concentrations of cadmium, arsenic, selenium, and zinc in blood and urine of nonsmoking women (n = 202) from the northern Argentinean Andes were measured by inductively coupled mass spectrometry. Methylation in CpG islands of LINE-1 (long interspersed nuclear element-1; a proxy for global DNA methylation) and promoter regions of p16 [cyclin-dependent kinase inhibitor 2A (CDKN2A)] and MLH1 (mutL homolog 1) in peripheral blood were measured by bisulfite polymerase chain reaction pyrosequencing. Genotyping (n = 172) for the DNA (cytosine-5-)-methyltransferase 1 gene (DNMT1 rs10854076 and rs2228611) and DNA (cytosine-5-)-methyltransferase 3 beta gene (DNMT3B rs2424913 and rs2424932) was performed with Sequenom iPLEX GOLD SNP genotyping; and gene expression (n = 90), with DirectHyb HumanHT-12 (version 3.0).Results: Cadmium exposure was low: median concentrations in blood and urine were 0.36 and 0.23 µg/L, respectively. Urinary cadmium (natural log transformed) was inversely associated with LINE-1 methylation (β = –0.50, p = 0.0070; β = –0.44, p = 0.026, adjusted for age and coca chewing) but not with p16 or MLH1 methylation. Both DNMT1 rs10854076 and DNMT1 rs2228611 polymorphisms modified associations between urinary cadmium and LINE-1 (p-values for interaction in adjusted models were 0.045 and 0.064, respectively). The rare genotypes demonstrated stronger hypomethylation with increasing urinary cadmium concentrations. Cadmium was inversely associated with DNMT3B (rS = –0.28, p = 0.0086) but not with DNMT1 expression (rS = –0.075, p = 0.48).Conclusion: Environmental cadmium exposure was associated with DNA hypomethylation in peripheral blood, and DNMT1 genotypes modified this association. The role of epigenetic modifications in cadmium-associated diseases needs clarification.

Effects of calcium supplementation on fetal growth in mothers with deficient calcium intake: a randomised controlled trial

Calcium supplementation in mothers with low calcium intake has been of interest recently because of its association with optimal fetal growth and improved pre-eclampsia-related outcomes. While the effects of calcium supplementation have demonstrated benefits in prolonging gestation and subsequently improving birthweight, no specific studies have identified the longitudinal effects of supplementation on fetal growth in utero. Data were analysed in the context of the World Health Organization trial of calcium supplementation in calcium-deficient women. Five hundred and ten healthy, primiparous pregnant Argentinean women were randomised (at <20 weeks gestation) to either placebo (n = 230) or calcium supplements (1500 mg calcium/day in 3 divided doses; n = 231). Growth parameters in utero were assessed with serial ultrasound scans. Birthweight, length, head, abdominal and thigh circumferences were recorded at delivery. No differences were found in fetal biometric measurements recorded at 20, 24, 28, 32 and 36 weeks gestation between fetuses of women who were supplemented with calcium and those who were not. Similarly, neonatal characteristics and anthropometric measurements recorded at delivery were comparable in both groups. We conclude that calcium supplementation of 1500 mg calcium/day in pregnant women with low calcium intake does not appear to impact on fetal somatic or skeletal growth.

Effects of calcium supplementation on uteroplacental and fetoplacental blood flow in low-calcium-intake mothers: a randomized controlled trial

We postulated that calcium supplementation of calcium-deficient pregnant women would lower vascular resistance in uteroplacental and fetoplacental circulations. Pulsatility index (PI) and resistance index (RI) (uterine and umbilical arteries) and presence of bilateral uterine artery diastolic notching were assessed by Doppler ultrasound between 20-36 weeks' gestation in 510 healthy, nulliparous Argentinean women with deficient calcium intake in a randomized, placebo-controlled, double-blinded trial. Average umbilical and uterine artery RI and PI tended to be lower in the supplemented group at each study week. Differences became statistically significant for umbilical artery RI and PI from 32 and 36 weeks, respectively. Estimated probabilities of bilateral uterine artery diastolic notching trended toward lower values in calcium-supplemented women. Calcium supplementation of pregnant women with deficient calcium intake may affect uteroplacental and fetoplacental blood flow by preserving the vasodilation of normal gestation.

Social Support and Cervical and Breast Cancer Screening in Argentinean Women From a Rural Population

To examine whether emotional social support influences the use of 3 cancer screening tests in females. Cross-sectional study. Data were collected via a household survey of a random sample of 200 Argentinean women. The questionnaire included self-reported data about the cancer screening tests (Papanicolaou [Pap] test for cervical cancer, breast self-examination, and clinical examination for breast cancer), and socioeconomic background information. Social support was measured by the Duke-UNC-11 questionnaire. Logistic models were used to investigate the association between social support and cancer screening tests. Emotional social support was associated with having participated in Pap screening within 3 years before this study, but a link between social support and self or clinical breast examination was not supported. Emotional social support may play a role in early cervical cancer detection among Argentinean females, specifically by encouraging performance of the Pap test. The educational practices accomplished by nurses should include actions that involve the family and community; therefore, emphasizing the importance of social ties on health and promoting interactions between target women and existent social groups in the community.

Pots, Pans, & Protests: Women's Strategies for Resisting Globalization in Argentina

This article uses the case study of Argentinean women and the cacerolazos protests to demonstrate women's resistance to globalization's economic injustices and how women are making their private concerns public. This discussion is preceded by a description of the public/private dichotomy as a way of understanding women's marginalization and oppression, specifically their suffering from global capitalist policies known as structural adjustment programs. The article argues that women are capable of accessing the public sphere and enforcing changes through collective action that both empowers women and politicizes their suffering.

Social inequality in Pap smear coverage: identifying under-users of cervical cancer screening in Argentina

In Argentina, the unequal distribution of the burden of cervical cancer is striking: the mortality rate of the province of Jujuy (15/100,000) is almost four times higher than that of the city of Buenos Aires (4/100,000). We aimed to establish the socio-demographic profile of women who were under-users of Pap smear screening, based on an analysis of a representative sample of Argentinean women from the First National Survey on Risk Factors in 2005. We found that in Argentina, women who are poor, unmarried, unemployed or inactive, with lower levels of education and reduced access to health care, and women over the age of 65, were under-users of screening. Screening must not remain opportunistic. Strategies must incorporate the needs and perceptions of socially disadvantaged women, and increase their access to screening. Of utmost importance is to provide good quality screening and treatment services that reach women who are at risk. Pilot projects using new, alternative technologies should be encouraged in less developed parts of the country. Promotion among health professionals of the scientific basis and effectiveness of each screening modality is essential to reduce wasteful practices such as annual screening and screening of young women that waste resources and fail to reduce cervical cancer incidence and mortality rates.
