Abstract
Background: Previous research shows that 61% of children younger than 6 months in low- and middle-income countries (LMICs) are not exclusively breastfed. Although data on the role of pre- and postnatal depression on breastfeeding exclusivity is mixed, fetomaternal attachment might foster breastfeeding exclusivity. Thus, we tested the potential mediating role of fetomaternal attachment and postnatal depression in the relationship between maternal prenatal depression and exclusive breastfeeding. Materials and Methods: Data were collected as part of a prospective, cross-cultural project, Evidence for Better Lives Study, which enrolled 1208 expectant mothers, in their third trimester of pregnancy across eight sites, from LMICs. Of the whole sample, 1185 women (mean age = 28.32, standard deviation [SD] = 5.77) completed Computer-Aided Personal Interviews on prenatal depressive symptoms, fetomaternal attachment, and socioeconomic status. A total of 1054 women provided follow-up data at 3-6 months after birth, about postnatal depressive symptoms, exclusive breastfeeding, and infant health indicators. Path analysis was used to assess parallel mediation. Results: In the whole sample, the effect of prenatal depression on breastfeeding exclusivity was completely mediated by postnatal depression, whereas fetomaternal attachment did not mediate the relationship. The full mediation effect was replicated individually in Pakistan and Sri Lanka. Conclusions: The study results indicate that prenatal depression symptoms contributed to the development of depressive symptoms after birth, negatively affecting the probability of exclusive breastfeeding. Future research should explore this in early prevention interventions, increasing the chances of healthy child development in LMICs. Considering the mixed results around the sites, it is important to better understand the relationship between maternal depression, fetomaternal attachment and breastfeeding behavior in each site's socio-cultural context.

Abstract
BACKGROUND Epidemiological studies assessing the influence of vegetarian diets on breast cancer (BC) risk have produced inconsistent results. Few studies have assessed how the incremental decrease in animal foods and the quality of plant foods are linked with BC. OBJECTIVES Disentangle the influence of plant-based diet quality on BC risk between postmenopausal females. METHODS Total of 65,574 participants from the E3N (Etude Epidémiologique auprès de femmes de la Mutuelle Générale de l'Education Nationale) cohort were followed from 1993-2014. Incident BC cases were confirmed through pathological reports and classified into subtypes. Cumulative average scores for healthful (hPDI) and unhealthful (uPDI) plant-based diet indices were developed using self-reported dietary intakes at baseline (1993) and follow-up (2005) and divided into quintiles. Cox proportional hazards models were used to estimate adjusted HR and 95% CI. RESULTS During a mean follow-up of 21 y, 3968 incident postmenopausal BC cases were identified. There was a nonlinear association between adherence to hPDI and BC risk (Pnonlinear < 0.01). Compared to participants with low adherence to hPDI, those with high adherence had a lower BC risk [HRQ3 compared withQ1 (95% CI): 0.79 (0.71, 0.87) and HRQ4 compared with Q1 (95% CI): 0.78 (0.70, 0.86)]. In contrast, higher adherence to unhealthful was associated with a linear increase in BC risk [Pnonlinear = 0.18; HRQ5 compared with Q1 (95% CI): 1.20 (1.08, 1.33); Ptrend < 0.01]. Associations were similar according to BC subtypes (Pheterogeneity > 0.05 for all). CONCLUSIONS Long-term adherence to healthful plant foods with some intake of unhealthy plant and animal foods may reduce BC risk with an optimal risk reduction in the moderate intake range. Adherence to an unhealthful plant-based diet may increase BC risk. These results emphasize the importance of the quality of plant foods for cancer prevention. This trial was registered at clinicaltrials.gov (NCT03285230).

Abstract
The survival after the diagnosis of inflammatory breast cancer (IBC) has been steadily improving for the past few decades. This has been due to advances in the knowledge of IBC in a number of fields, including epidemiology, molecular biology, and medical management. In this review we summarize some of the most important recent advances in these fields and suggest possible opportunities for continued improvement.

Abstract
Background A paucity of research addresses breast cancer screening strategies for women at lower-than-average breast cancer risk. The aim of this study was to examine screening harms and benefits among women aged 50-74 years at lower-than-average breast cancer risk by breast density. Methods Three well-established, validated Cancer Intervention and Surveillance Network models were used to estimate the lifetime benefits and harms of different screening scenarios, varying by screening interval (biennial, triennial). Breast cancer deaths averted, life-years and quality-adjusted life-years gained, false-positives, benign biopsies, and overdiagnosis were assessed by relative risk (RR) level (0.6, 0.7, 0.85, 1 [average risk]) and breast density category, for US women born in 1970. Results Screening benefits decreased proportionally with decreasing risk and with lower breast density. False-positives, unnecessary biopsies, and the percentage overdiagnosis also varied substantially by breast density category; false-positives and unnecessary biopsies were highest in the heterogeneously dense category. For women with fatty or scattered fibroglandular breast density and a relative risk of no more than 0.85, the additional deaths averted and life-years gained were small with biennial vs triennial screening. For these groups, undergoing 4 additional screens (screening biennially [13 screens] vs triennially [9 screens]) averted no more than 1 additional breast cancer death and gained no more than 16 life-years and no more than 10 quality-adjusted life-years per 1000 women but resulted in up to 232 more false-positives per 1000 women. Conclusion Triennial screening from age 50 to 74 years may be a reasonable screening strategy for women with lower-than-average breast cancer risk and fatty or scattered fibroglandular breast density.

Abstract
Although little is known regarding the mechanisms behind the onset of breast cancer (BC) through reproductive risk factors, new researches have highlighted some early tumor-related methylation footmarks in the breast tissue of apparently clinically healthy women as their potential epigenetic mechanism. Previous evidence supports that the estrogen receptor beta (ER-β), whose anti-cancer roles had already been revealed in BC, is downregulated in the breasts of healthy nulliparous women. Nevertheless, data on such a link about its methylation alterations have not been reported. The goal of current study was to determine possible methylation alterations at CpG island promoter of the ER-β gene, including promoter 0 N and exon 0 N, in relation to aspects of reproductive history in the healthy breasts. The DNA was extracted from the breasts of 120 subjects undergoing cosmetic mammoplasty. Thereafter, the methylation levels of targeted regions in ER-β gene were determined by using MeDIP-qPCR assay. The results revealed that ER-β exon 0 N had no methylation in 84.2 % of the women, whereas the rest, comprising 2.5 % and 13.3 % of the samples, showed a lower and higher of its methylation, respectively. Interestingly, nulliparous women were found to have an elevated methylation level of the ER-β exon 0 N than parous women (P = 0.036). Moreover, we observed a high methylation of the ER-β exon 0 N in the breasts of non-breastfeeding women compared to breastfeeding subgroup (P = 0.048). Likewise, the non-breastfeeding subgroup showed exon 0N high methylation in comparison to women with breastfeeding >24 months (P = 0.023). Finally, although we found that 6.67 % of the samples had a high methylation level at the promoter 0N, no any relationship was found between its methylation and reproductive history. These results may provide key clues to revealing the epigenetic mechanism through which the nulliparity and lack of breastfeeding influencing the risk factor of BC as well as introducing the potential new early prediction and prevention strategies. Although further investigations need to be done in order to gain a better understanding the roles of these epigenetic signatures.

Abstract
The presence of microcalcifications in the breast microenvironment, combined with the growing evidences of the possible presence of osteoblast-like or osteoclast-like cells in the breast, suggest the existence of active processes of calcification in the breast tissue during a woman’s life. Furthermore, much evidence that osteoimmunological disorders, such as osteoarthritis, rheumatoid arthritis, or periodontitis influence the risk of developing breast cancer in women exists and vice versa. Antiresorptive drugs benefits on breast cancer incidence and progression have been reported in the past decades. More recently, biological agents targeting pro-inflammatory cytokines used against rheumatoid arthritis also demonstrated benefits against breast cancer cell lines proliferation, viability, and migratory abilities, both in vitro and in vivo in xenografted mice. Hence, it is tempting to hypothesize that breast carcinogenesis should be considered as a potential osteoimmunological disorder. In this review, we compare microenvironments and molecular characteristics in the most frequent osteoimmunological disorders with major events occurring in a woman’s breast during her lifetime. We also highlight what the use of bone anabolic drugs, antiresorptive, and biological agents targeting pro-inflammatory cytokines against breast cancer can teach us.

Abstract
OBJECTIVES Breast cancer is known as one of the deadliest forms of cancer, and it is increasing globally. There are a variety of proven and controversial risk factors for this malignancy. Herein, we aimed to undertake a systematic review and meta-analysis focus on the epidemiology of breast cancer risk factors in Iran. METHODS We performed a systematic search via PubMed, Scopus, Web of Science, and Persian databases for identifying studies published on breast cancer risk factors up to March 2019. Meta-analyses were done for risk factors reported in more than one study. We calculated odds ratios (ORs) with corresponding 95% confidence intervals (CIs) using a fixed/random-effects models. RESULTS Thirty-nine studies entered into the meta-analysis. Pooling of ORs showed a significant harmful effect for risk factors including family history (OR: 1.80, 95%CI 1.47-2.12), hormonal replacement therapy (HRT) (OR: 5.48, 95%CI 0.84-1.74), passive smokers (OR: 1.68, 95%CI 1.34-2.03), full-term pregnancy at age 30 (OR: 3.41, 95%CI 1.19-5.63), abortion (OR: 1.84, 95%CI 1.35-2.33), sweets consumption (OR: 1.71, 95%CI 1.32-2.11) and genotype Arg/Arg (crude OR: 1.59, 95%CI 1.07-2.10), whereas a significant protective effect for late menarche (OR: 0.58, 95%CI 0.32-0.83), nulliparity (OR: 0.68, 95%CI 0.39-0.96), 13-24 months of breastfeeding (OR: 0.68, 95%CI 0.46-0.90), daily exercise (OR: 0.59, 95%CI 0.44-0.73) and vegetable consumption (crude OR: 0.28, 95%CI 0.10-0.46). CONCLUSIONS This study suggests that factors such as family history, HRT, passive smokers, late full-term pregnancy, abortion, sweets consumption and genotype Arg/Arg might increase risk of breast cancer development, whereas late menarche, nulliparity, 13-24 months breastfeeding, daily exercise and vegetable consumption had an inverse association with breast cancer development.

Abstract
Background Overweight and obesity are major risk factors for gestational diabetes among U.S. women. Evidence suggests that longer duration of breastfeeding among women with a history of gestational diabetes is associated with lower incidence of developing type 2 diabetes after pregnancy. Women may potentially benefit from a lifestyle change program that includes breastfeeding education and support. Purpose To describe the design and justification of a combined breastfeeding, national Diabetes Prevention Program (DPP)-based feasibility randomized controlled trial, the electronic Monitoring Of Mom's Schedule (eMOMSTM) study. eMOMSTM compares the feasibility and efficacy of three interventions on six-month postpartum weight loss among women with a BMI ≥25. Methods The intervention is delivered via Facebook and includes three groups: DPP and breastfeeding (eMOMS1); DPP only (eMOMS2); and Usual Care (eMOMS3). Recruitment is ongoing at two clinical sites (rural and urban). A total of 72 women, 24 per group, will be randomly assigned to one of the three groups. It is anticipated that women in eMOMS1 will have greater weight loss and increased length of breastfeeding at three and six months postpartum compared to women in eMOMS2 and eMOMS3. Additional data will be collected on metabolic markers, anthropometrics, physical activity, nutrition, breastfeeding, and depression. Program cost will be compared to that of traditionally scheduled group meetings. Expected study completion date: October 2021. Conclusions This study has the potential to define a high impact, cost effective intervention that can improve public health by reducing negative health outcomes associated with gestational diabetes among an at-risk population.

Abstract
Several studies have made strong efforts to understand how age and parity modulate the risk of breast cancer. A holistic understanding of the dynamic regulation of the morphological, cellular, and molecular milieu of the mammary gland offers insights into the drivers of breast cancer development as well as into potential prophylactic interventions, the latter being a longstanding ambition of the research and clinical community aspiring to eradicate the disease. In this review we discuss mechanisms that react to pregnancy signals, and we delineate the nuances of pregnancy-associated dynamism that contribute towards either breast cancer development or prevention. Further definition of the molecular basis of parity and breast cancer risk may allow the elaboration of tools to predict and survey those who are at risk of breast cancer development.

Abstract
Background Stroke is the third leading cause of death among US Hispanic and non-Hispanic black women aged 65 and older. One factor that may protect against stroke is breastfeeding. Few studies have assessed the association between breastfeeding and stroke and whether this association differs by race and ethnicity. Methods and Results Data were taken from the Women's Health Initiative Observational Study with follow-up through 2010; adjusted hazard ratios for stroke subsequent to childbirth were estimated with Cox regression models accounting for left and right censoring, overall and stratified by race/ethnicity. Of the 80 191 parous women in the Women's Health Initiative Observational Study, 2699 (3.4%) had experienced a stroke within a follow-up period of 12.6 years. The average age was 63.7 years at baseline. Fifty-eight percent (n=46 699) reported ever breastfeeding; 83% were non-Hispanic white, 8% were non-Hispanic black, 4% were Hispanic, and 5% were of other race/ethnicity. After adjustment for nonmodifiable potential confounders, compared with women who had never breastfed, women who reported ever breastfeeding had a 23% lower risk of stroke (adjusted hazard ratio=0.77; 95% confidence interval 0.70-0.83). This association was strongest for non-Hispanic black women (adjusted hazard ratio=0.52; 95% confidence interval 0.37-0.71). Further, breastfeeding for a relatively short duration (1-6 months) was associated with a 19% lower risk of stroke (adjusted hazard ratios=0.81; 95% confidence interval 0.74-0.89). This association appeared stronger with longer breastfeeding duration and among non-Hispanic white and non-Hispanic black women (test for trend P<0.01). Conclusions Study results show an association and dose-response relationship between breastfeeding and lower risk of stroke among postmenopausal women after adjustment for multiple stroke risk factors and lifestyle variables. Further investigation is warranted.

Abstract
Objectives The purpose of this study was to examine the associations of childbirth, breastfeeding, and their interaction with breast cancer (BC) risk reduction, and to evaluate the heterogeneity in the BC risk reduction effects of these factors by menopause, hormone receptor (HR) status, and pathological subtype. Methods BC patients aged 40+ from the Korean Breast Cancer Registry in 2004-2012 and controls from the Health Examinee cohort participants were included in this study after 1:1 matching (12 889 pairs) by age and enrollment year. BC risk according to childbirth, breastfeeding, and their interaction was calculated in logistic regression models using odds ratios (ORs) and 95% confidence intervals (CIs). Results BC risk decreased with childbirth (3+ childbirths relative to 1 childbirth: OR, 0.66; 95% CI, 0.56 to 0.78 and OR, 0.80; 95% CI, 0.68 to 0.95 in postmenopausal and premenopausal women, respectively); and the degree of risk reduction by the number of children was heterogeneous according to menopausal status (p-heterogeneity=0.04), HR status (p-heterogeneity<0.001), and pathological subtype (p-heterogeneity<0.001); whereas breastfeeding for 1-12 months showed a heterogeneous association with BC risk according to menopausal status, with risk reduction only in premenopausal women (p-heterogeneity<0.05). The combination of 2 more childbirths and breastfeeding for ≥13 months had a much stronger BC risk reduction of 49% (OR, 0.51; 95% CI, 0.45 to 0.58). Conclusions This study suggests that the combination of longer breastfeeding and more childbirths reduces BC risk more strongly, and that women who experience both 2 or more childbirths and breastfeed for ≥13 months can reduce their BC risk by about 50%.

Abstract
Women who engage in prenatal physical activity give themselves, and their child, an advantage over women who did not engage in prenatal physical activity; not only are there significant health benefits for mothers, but there are also great benefits for the unborn child. Breastfeeding is another important decision parents make that can affect the mother and her child. There has been extensive research on the benefits of both prenatal physical activity and breastfeeding, but the connection between the two is unclear. The purpose of this grounded theory article was to identify potential connections between factors influencing women's decisions to engage in prenatal physical activity and breastfeeding among mothers in a medium-sized city in Tennessee. Responses from mothers revealed numerous themes related to both prenatal physical activity and breastfeeding. Connections between prenatal physical activity and breastfeeding, in addition to an overarching theme that captured the women's collective experience, were identified.

Abstract
BACKGROUND Reproductive factors are among the most well-established risk factors for breast cancer. However, their associations with different breast cancer subtypes defined by joint estrogen receptor (ER)/progesterone receptor (PR)/HER2 status remain unclear. METHODS We assessed relationships between reproductive factors and risks of luminal A (ER(+)/HER2(-)), luminal B (ER(+)/HER2(+)), triple-negative (TN; ER(-)/PR(-)/HER2(-)), and HER2-overexpressing (H2E; ER(-)/HER2(+)) breast cancers in a population-based case-case study consisting of 2,710 women ages 20-69 years diagnosed between 2004 and 2012. ORs and 95% confidence intervals (CI) were estimated with luminal A cases serving as the reference group using polytomous logistic regression. RESULTS Earlier age at first full-term pregnancy and age at menopause were positively associated with odds of TN breast cancer (Ptrend: 0.003 and 0.024, respectively). Parity was associated with a 43% (95% CI, 1.08-1.89) elevated odds of H2E breast cancer, and women who had ≥3 full-term pregnancies had a 63% (95% CI, 1.16-2.29, Ptrend = 0.013) increased odds of this subtype compared with nulliparous women. Breast feeding for ≥36 months was associated with a 49% (OR 0.51; 95% CI, 0.27-0.99) lower odds of TN breast cancer. CONCLUSION Our results suggest that reproductive factors contribute differently to risks of the major molecular subtypes of breast cancer. IMPACT African American and Hispanic women have higher incidence rates of the more aggressive TN and H2E breast cancers and their younger average age at first pregnancy, higher parity, and less frequent breast feeding could in part contribute to this disparity.

Abstract
BACKGROUND Exclusive breastfeeding rates (EBRs) may be influenced by sociodemographic and sociocultural factors, including maternal age, socioeconomic status, education, and breastfeeding knowledge. The EBR in Jamaica has been low and declining, leaving a need for better determination of the specific local contributory factors. OBJECTIVES This study aimed to better elucidate the factors that influence mothers exclusively breastfeeding, including antenatal intentions to breastfeed, mothers' knowledge of the benefits of breastfeeding, and mothers' infant feeding practices in general, inclusive of breastfeeding, formula feeding, and complementary feeding. METHODS A cross-sectional survey was conducted using a 52-item interviewer-administered questionnaire with mothers attending their 6-week postnatal clinic visit. Sociodemographic data were collected on all participants as well as data regarding participants' breastfeeding knowledge, attitudes, and practices. Statistical analyses were done using χ(2) tests, t tests, and risk analyses. RESULTS Two hundred participants were interviewed; the mean ± SD age of participants was 26.2 ± 6.46 years (range, 15-46 years). The EBR in this study sample was 32%. Sociodemographic factors, including maternal age and socioeconomic status, as well as antenatal and postnatal breastfeeding sessions, did not significantly affect the likelihood of exclusively breastfeeding at 6 weeks postpartum. The only factor significantly associated with the EBR was mothers' belief that exclusively breastfeeding was able to ensure infant satiety. CONCLUSION Antenatal and postnatal breastfeeding sessions should place more emphasis on dispelling maternal myths and misperceptions regarding signs of satiety and hunger in infants and reinforcing the knowledge that breast milk alone is sufficient for the first 6 months of life.

Abstract
Breastfeeding can reduce breast cancer risk; however, unknown factors modify this protective effect. Zinc (Zn) modulates an array of cellular functions including oxidative stress, cell proliferation, motility and apoptosis. Marginal Zn intake is common in women and is associated with breast cancer. We reported that marginal Zn intake in mice leads to mammary gland hypoplasia and hallmarks of pre-neoplastic lesions. In the present study, we tested the hypothesis that marginal Zn intake confounds the protective effect of lactation on breast cancer. Nulliparous mice fed control (ZA, 30 mg Zn/kg) or a marginal Zn diet (ZD, 15 mg Zn/kg), were bred and offspring were weaned naturally. Post-involution, mice were gavaged with corn oil or 7,12-dimethylbenz(a)anthracene (DMBA, 1 mg/wk for 4 weeks) and tumor development was monitored. A ZD diet led to insufficient involution, increased fibrosis and oxidative stress. Following DMBA treatment, mice fed ZD had higher oxidative stress in mammary tissue that correlated with reduced levels of peroxiredoxin-1 and p53 and tended to have shorter tumor latency and greater incidence of non-palpable tumors. In summary, marginal Zn intake creates a toxic mammary gland microenvironment and abrogates the protective effect of lactation on carcinogenesis.

Abstract
The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) is a public nutritional assistance program for low-income women and their children up to age five. This study provides insight into maternal characteristics associated with breastfeeding among urban versus rural women. A secondary analysis was conducted using the Pregnancy Nutrition Surveillance System dataset of women enrolled in the Kansas WIC program in 2011. Geographic residency status was obtained through application of the Census tract-based rural-urban commuting area codes. Descriptive variables included maternal demographics, health, and lifestyle behaviors. A multivariable binary logistic regression was used to obtain adjusted odds ratios with 95 % confidence intervals. The outcome variable was initiation of breastfeeding. A P value of ≤0.05 was considered statistically significant. The total sample size was 17,067 women. Statistically significant differences regarding socio-demographics, program participation, and health behaviors for urban and rural WIC participants were observed. About 74 % of all WIC mothers initiated breastfeeding. Urban women who were Hispanic, aged 18-19, high school graduates, household income >$10,000/year, and started early prenatal care were more likely to breastfeed. Urban and rural women who were non-Hispanic black with some high school education were less likely to breastfeed. Increased breastfeeding initiation rates are the result of a collaborative effort between WIC and community organizations. Availability of prenatal services to rural women is critical in the success of breastfeeding promotion. Findings help inform WIC program administrators and assist in enhancing breastfeeding services to the Kansas WIC population.

Abstract
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.

Abstract
Introduction The pattern and duration of breastfeeding (BF) and the age at onset of complementary feeding, as well as its quality, have been associated with the prevalence of overweight in childhood. Objective To assess the effect of a pro-BF and healthy complementary feeding intervention, targeted to adolescent mothers and maternal grandmothers, on growth and prevalence of overweight and obesity in children at preschool age. This intervention had a positive impact on duration of BF and timing of onset of complementary feeding. Methods This randomized clinical trial involved 323 adolescent mothers, their infants, and the infants’ maternal grandmothers, when they cohabited. Mothers and grandmothers in the intervention group received counseling sessions on BF and healthy complementary feeding at the maternity ward and at home (7, 15, 30, 60, and 120 days after delivery). When children were aged 4 to 7 years, they underwent anthropometric assessment and collection of data on dietary habits. Multivariable Poisson regression with robust estimation was used for analysis. Results BMI-for-age and height-for-age were similar in the intervention and control groups, as was the prevalence of overweight (39% vs. 31% respectively; p=0.318). There were no significant between-group differences in dietary habits. Conclusion Although the intervention prolonged the duration of exclusive BF and delayed the onset of complementary feeding, it had no impact on growth or prevalence of overweight at age 4 to 7 years.

Abstract
BACKGROUND Quantification of the association between breastfeeding and breast cancer risk is still conflicting. Therefore, we conducted a meta-analysis to summarize the evidence from epidemiological studies of breastfeeding with the risk of breast cancer. MATERIALS AND METHODS Pertinent studies were identified by a search of PubMed between January 1, 2008 and July 31, 2014. The random-effect model was used. Sensitivity analysis, subgroups analysis, and publication bias were conducted. RESULTS Twenty-four articles with 27 studies involving 13,907 breast cancer cases were included in this meta-analysis. Pooled results suggested that breastfeeding was inversely [corrected] associated with the risk of breast cancer. The summary relative risk (RR) of breast cancer for the ever compared with never categories of breastfeeding was 0.613 (95% confidence interval [CI], 0.442-0.850). An inverse association was also found for the longest compared with the shortest categories of breastfeeding with the risk of breast cancer (RR=0.471; 95% CI, 0.368-0.602). No evidence of publication bias was found. CONCLUSIONS Findings from this meta-analysis suggest that breastfeeding, particularly a longer duration of breastfeeding, was inversely associated with risk of breast cancer.

Abstract
A large genotyping project within the Breast Cancer Association Consortium (BCAC) recently identified 41 associations between single nucleotide polymorphisms (SNPs) and overall breast cancer (BC) risk. We investigated whether the effects of these 41 SNPs, as well as six SNPs associated with estrogen receptor (ER) negative BC risk are modified by 13 environmental risk factors for BC. Data from 22 studies participating in BCAC were pooled, comprising up to 26,633 cases and 30,119 controls. Interactions between SNPs and environmental factors were evaluated using an empirical Bayes-type shrinkage estimator. Six SNPs showed interactions with associated p-values (pint ) <1.1 × 10(-3) . None of the observed interactions was significant after accounting for multiple testing. The Bayesian False Discovery Probability was used to rank the findings, which indicated three interactions as being noteworthy at 1% prior probability of interaction. SNP rs6828523 was associated with increased ER-negative BC risk in women ≥170 cm (OR = 1.22, p = 0.017), but inversely associated with ER-negative BC risk in women <160 cm (OR = 0.83, p = 0.039, pint = 1.9 × 10(-4) ). The inverse association between rs4808801 and overall BC risk was stronger for women who had had four or more pregnancies (OR = 0.85, p = 2.0 × 10(-4) ), and absent in women who had had just one (OR = 0.96, p = 0.19, pint = 6.1 × 10(-4) ). SNP rs11242675 was inversely associated with overall BC risk in never/former smokers (OR = 0.93, p = 2.8 × 10(-5) ), but no association was observed in current smokers (OR = 1.07, p = 0.14, pint = 3.4 × 10(-4) ). In conclusion, recently identified BC susceptibility loci are not strongly modified by established risk factors and the observed potential interactions require confirmation in independent studies.

Abstract
The present systematic review and meta-analysis was conducted to assess any association between breastfeeding and the risk of ovarian cancer. A systematic search of published studies was performed in PUBMED and EMBASE and by reviewing reference lists from retrieved articles through March 2013. Data extraction was conducted independently by two authors. Pooled relative risk ratios were calculated using random-effect models. Totals of 5 cohort studies and 35 case-control studies including 17,139 women with ovarian cancer showed a 30% reduced risk of ovarian cancer when comparing the women who had breastfed with those who had never breastfed (pooled RR = 0.70, 95% CI: 0.64-0.76; p = 0.00), with significant heterogeneity in the studies (p = 0.00; I2 = 76.29%). A significant decreasd in risk of epithelial ovarian cancer was also observed (pooled RR = 0.68, 95% CI: 0.61-0.76). When the participants were restricted to only parous women, there was a slightly attenuated but still significant risk reduction of ovarian cancer (pooled RR = 0.76, 95% CI: 0.69-0.83). For total breastfeeding duration, the pooled RRs in the < 6 months, 6-12 months and > 12 months of breastfeeding subgroups were 0.85 (95% CI: 0.77-0.93), 0.73 (95% CI: 0.65-0.82) and 0.64 (95%CI: 0.56-0.73), respectively. Meta-regression of total breastfeeding duration indicated an increasing linear trend of risk reduction of ovarian cancer with the increasing total breastfeeding duration (p = 0.00). Breastfeeding was inversely associated with the risk of ovarian cancer, especially long-term breastfeeding duration that demonstrated a stronger protective effect.

Abstract
The aim of the present article was to study the prevalence and the heritability of the initiation of breastfeeding in the Netherlands. The study was carried out in 5,581 participants from the Netherlands Twin Register, and included female twins, their sisters and mothers. All of the participants were born between 1911 and 1991. Breastfeeding was self-reported by the participants, and its prevalence was estimated conditional on birth cohort (born before 1955, 1955-1964, 1965-1974, 1975, or later). To estimate the heritability, we conducted extended twin-family modeling using the SEM package OpenMx in R. Mothers of twins had lower prevalence to initiate breastfeeding and the prevalence of initiation of breastfeeding increased with birth cohort: among mothers of twins 66% in the oldest (pre-1955) to 74% in the youngest (post-1974) and among mothers, who were twins themselves or sisters of twins, 79% in the oldest (pre-1955) to 85% in the youngest (post-1974). When accounting for prevalence differences between mothers of twins and other women, heritability of initiation of breastfeeding was 70%. However, the familial resemblance for sister and mother-daughter pairs was clearly lower than for DZ twin pairs, but as the number of non-twin sisters was relatively low, this observation did not lead to a significant contribution of a special shared twin environment.

Abstract
INTRODUCTION Germline mutations BRCA1&2 are responsible in women for breast and ovarian cancers that commonly occur at a young age: as such, there are strong interactions between the oncological risks and the events of reproductive life, pregnancy, breastfeeding, and management of infertility. MATERIALS AND METHODS A review of the international literature from the PubMed database was conducted, and recommendations of French health agencies were exposed. Published studies are case-control and cohort studies in the majority, with a low level of evidence. RESULTS Pregnancy and lactation have no effect on breast and ovaries or even decreases the risk. The sex ratio among patients carrying the mutation is in favor of girls. It is not observed more infertility in patients carrying a mutation despite a strong suspicion of premature ovarian failure, and infertility treatments do not increase breast and ovarian risk. There are ethical debates concerning the place of pre-natal diagnosis: both experts and concerned patients recommend a case-by-case analysis of the requests.

Abstract
Across the state of Kansas, eighteen public health departments received funding through the 2011 Breastfeeding Grant Initiative to start a breastfeeding intervention. The main objective of this study was to evaluate the progress toward program goals and objectives. This study was a process evaluation. Qualitative data were collected from recipient health departments at two time-points during the program year. Structured, open-ended questions were asked through telephone interviews. This study examined: (1) progress toward program goals and objectives, (2) problems encountered during implementation, and (3) evaluation measures employed to assess program impact. All health departments reported making significant progress toward program goals and objectives and reported successful collaboration with other healthcare providers. The use of breast pumps, educational classes, and professional training of staff were reported as providing the best outcome in the promotion of breastfeeding. The majority of respondents did not measure program impact. From a public health perspective, it is important that infants receive breast milk for the first six months of life. It appears that goals and objectives set a priori guided health departments with the administration of their breastfeeding program. Results may be used to enhance and sustain delivery of breastfeeding support programs in Kansas communities.

Abstract
Postpartum mammary gland involution has been identified as tumor-promotional and is proposed to contribute to the increased rates of metastasis and poor survival observed in postpartum breast cancer patients. In rodent models, the involuting mammary gland microenvironment is sufficient to induce enhanced tumor cell growth, local invasion, and metastasis. Postpartum involution shares many attributes with wound healing, including upregulation of genes involved in immune responsiveness and infiltration of tissue by immune cells. In rodent models, treatment with non-steroidal anti-inflammatory drugs (NSAIDs) ameliorates the tumor-promotional effects of involution, consistent with the immune milieu of the involuting gland contributing to tumor promotion. Currently, immunotherapy is being investigated as a means of breast cancer treatment with the purpose of identifying ways to enhance anti-tumor immune responses. Here we review evidence for postpartum mammary gland involution being a uniquely defined 'hot-spot' of pro-tumorigenic immune cell infiltration, and propose that immunotherapy should be explored for prevention and treatment of breast cancers that arise in this environment.

Abstract
Mothers who breastfeed typically exhibit lower levels of depressive symptomatology than mothers who do not. However, very few studies have investigated the directionality of this relationship. Of the prospective studies published, all but one focus exclusively on whether maternal depression reduces rates of subsequent breastfeeding. This study again examines this relationship, but also the reverse-that breastfeeding might predict lower levels of later depression. Using multilevel modeling, we investigated the relationship between breastfeeding and self-reported depressive symptomatology in 205 women followed prenatally and at 3, 6, 12, and 24 months after birth. Consistent with previous research, women with prenatal depressive symptomatology weaned their infants 2.3 months earlier, on average, than women without such symptomatology. We also found, however, that women who breastfed more frequently at 3 months postpartum showed greater subsequent declines in depressive symptomatology over time compared to women who breastfed less frequently, resulting in lower absolute levels of depressive symptoms by 24 months postpartum, controlling for important confounds. In sum, these findings are consistent with a bidirectional association between breastfeeding and depression, with prenatal depression predicting less breastfeeding soon after birth and breastfeeding predicting declines in maternal depression up to 2 years after birth. We discuss mechanisms that could potentially explain these associations and avenues for future research.

Abstract
BACKGROUND Breast cancer is the most common cancer of women and the principal cause of death in middle aged women. The objective of this study was to describe the trend of breast cancer and its management in Aden and adjacent south-eastern governorates of Yemen during the last 20 years. PATIENTS AND METHODS This is a retrospective analysis of previous studies on patients with breast cancer in Aden and adjacent south-eastern governorates, Yemen (January 1989 through December 2007). The studied variables were: sex, age, time and type of presentation, disease stage, pathological types and the performed surgical treatment. The sources of information were the treatment registry of Aden health office, archives of Al-Gamhouria teaching hospital; major referral and other public and private hospitals in Aden and Aden Cancer Registry. RESULTS The total number of patients was 476, 99% being females. The age range was 19-88 years. The most affected age was 30-50 years (60.5%), 95% presenting after one month of having breast symptoms. Forty-five percent presented with signs of advanced local disease, while 59.2% had palpable axillary lymph nodes on presentation. Early breast cancer (stages I-II) occurred in 47%, and late breast cancer (stages III-IV) in 51.5%. Invasive ductal carcinoma was the commonest pathology (89.3%). The main surgical treatment was mastectomy (modified radical mastectomy (50%). CONCLUSION Breast cancer is predominantly a disease of young with late presentation and advanced disease. Improving health awareness and earlier diagnosis of the disease by health education, encouraging breast self-examination, and providing the mammography equipment and mammary clinics in hospitals are recommended. Establishment of oncology and radiotherapy centers in Aden is a necessity.

Abstract
The etiology of breast cancer might be explained by 2 mechanisms, namely, differentiation and proliferation of breast epithelial cells mediated by hormonal factors. We performed a systematic review and meta-analysis to update effects of risk factors for both mechanisms. MEDLINE and EMBASE were searched up to January 2011. Studies that assessed association between oral contraceptives (OC), hormonal replacement therapy (HRT), diabetes mellitus (DM), or breastfeeding and breast cancer were eligible. Relative risks with their confidence intervals (CIs) were extracted. A random-effects method was applied for pooling the effect size. The pooled odds ratios of OC, HRT, and DM were 1.10 (95% CI = 1.03-1.18), 1.23 (95% CI = 1.21-1.25), and 1.14 (95% CI = 1.09-1.19), respectively, whereas the pooled odds ratio of ever-breastfeeding was 0.72 (95% CI = 0.58-0.89). Our study suggests that OC, HRT, and DM might increase risks, whereas breastfeeding might lower risks of breast cancer.

Abstract
The pregnancy-lactation cycle (PLC) is a period in which the breast is transformed from a less-developed, nonfunctional organ into a mature, milk-producing gland that has evolved to meet the nutritional, developmental, and immune protection needs of the newborn. Cessation of lactation initiates a process whereby the breast reverts to a resting state until the next pregnancy. Changes during this period permanently alter the morphology and molecular characteristics of the breast (molecular histology) and produce important, yet poorly understood, effects on breast cancer risk. To provide a state-of-the-science summary of this topic, the National Cancer Institute invited a multidisciplinary group of experts to participate in a workshop in Rockville, Maryland, on March 2, 2012. Topics discussed included: 1) the epidemiology of the PLC in relation to breast cancer risk, 2) breast milk as a biospecimen for molecular epidemiological and translational research, and 3) use of animal models to gain mechanistic insights into the effects of the PLC on breast carcinogenesis. This report summarizes conclusions of the workshop, proposes avenues for future research on the PLC and its relationship with breast cancer risk, and identifies opportunities to translate this knowledge to improve breast cancer outcomes.

Abstract
OBJECTIVE This study characterized maternity hospital breastfeeding practices in New York. METHODS The New York State Department of Health Breastfeeding Survey was sent to 138 hospitals providing maternity services to assess breastfeeding and rooming-in policies, infant feeding practices, breastfeeding training, staff structure, and support mechanisms. Additionally, hospital-specific exclusive breastfeeding rates were obtained from Hospital Profile data. RESULTS The response rate was 100%. Ninety-three percent of the hospitals allowed 24-hour rooming-in, in all postpartum rooms. Eighty-six percent of hospitals employed a designated lactation coordinator. Less than 1.5% of hospitals routinely gave formula, pacifiers, or glucose water to a breastfed infant. These supplements are most commonly provided because of the mother's request. The largest reported barrier to initiating breastfeeding in the hospital was presenting mothers with mixed messages, whereas the largest patient barrier was identified as the mother's culture. All hospitals provided obstetric nursing staff with lactation education, whereas 46.4% trained physicians. Among healthy births, exclusive breastfeeding was statistically more likely to occur in hospitals offering only basic care (Level I) or subspecialty care (Level III), relative to Regional Perinatal Centers delivering the highest level of care, and was more likely with hospitals outside of New York City, relative to those within the city. After controlling for hospital location and level of care, exclusive breastfeeding was statistically more likely in hospitals that initiate breastfeeding immediately following an uncomplicated vaginal or cesarean birth. CONCLUSIONS Mothers should be encouraged to initiate breastfeeding immediately after birth. Practices of Level I hospitals that lead to increased breastfeeding should be identified.

Abstract
BACKGROUND Breast cancer (BC) is the most prevalent cancer in Iranian women and the fifth most common cause of cancer-related death in Iran. Among predicting factors and preventive measures for BC, the parity and breastfeeding (BF) are controversial issues. We therefore conducted this case-control study to find out the relation of parity and BF to incidence and risk of BC. METHOD A structured questionnaire that covered demographic criteria and BC risk factors was completed for case (376 cases) and control (425 subjects) groups, both matched in terms of demographic variants, reproductive issues, and socioeconomic status. Odds ratio (OR) and 95% confidence intervals (CI) were computed as measures of association from the logistic models. All p values reported are two-sided. RESULTS Parity significantly reduces the risk of BC (p < 0.001, OR 2.05, CI 1.4-3.3), and BF is protective (p = 0.0001, OR 0.39, CI 0.27-0.56). The best result was gained with 1-3 parity and 24 months BF and mean duration of 18-24 months per child (p = 0.037, OR 0.7, CI 0.5-0.98). CONCLUSION On the basis of breast anatomical and physiological changes during pregnancy, and parity and breastfeeding, full-term pregnancies and parities with efficient BF significantly reduced the risk of breast cancer compared with nonpregnant and nulliparous women or those who never breastfed. The number of children should ideally be limited to 1-3, and the cumulative duration of BF not less than 25-36 months. We would recommend 1-3 pregnancies and a BF duration not less than 18 months, with best results being achieved with 24 months per child.

Abstract
Infant feeding decisions affect maternal and child health outcomes, worldwide. Even in settings with clean water and good sanitation, infants who are not breast-fed face an increased risk of infectious, as well as non-infectious morbidity and mortality. The decision not to breast-feed can also adversely affect mothers' health by increasing the risk of pre-menopausal breast cancer, ovarian cancer, type II diabetes, hypertension, hyperlipidemia and cardiovascular disease. Clinicians who counsel mothers about the health impact of infant feeding and provide evidence-based care to maximize successful breast-feeding, can improve the short and long-term health of both mothers and infants.

Abstract
OBJECTIVES This article summarizes the Agency for Healthcare Research and Quality's evidence report on the effects of breastfeeding on term infant and maternal health outcomes in developed countries. EVIDENCE REPORT DATA SOURCES Medline, CINAHL, Cochrane Library, bibliographies of selected reviews, and suggestions from domain experts were surveyed. Searches were limited to English-language publications. EVIDENCE REPORT REVIEW METHODS Eligible comparisons examined the association between differential exposure to breastfeeding and health outcomes. We assessed 15 infant and six maternal outcomes. For four outcomes, we also updated previously published systematic reviews. For the rest of the outcomes, we either summarized previous systematic reviews or conducted new systematic reviews; randomized and non-randomized comparative trials, prospective cohorts, and case-control studies were included. Adjusted estimates were extracted from non-experimental designs. The studies were graded for methodological quality. We did not draw conclusions from poor quality studies. EVIDENCE REPORT RESULTS We screened over 9,000 abstracts. Thirty-two primary studies on term infant health outcomes, 43 primary studies on maternal health outcomes, and 28 systematic reviews or meta-analyses that covered approximately 400 individual studies were included in this review. A history of breastfeeding was associated with a reduction in the risk of acute otitis media, nonspecific gastroenteritis, severe lower respiratory tract infections, atopic dermatitis, asthma (young children), obesity, type 1 and 2 diabetes, childhood leukemia, and sudden infant death syndrome. There was no relationship between breastfeeding in term infants and cognitive performance. There were insufficient good quality data to address the relationship between breastfeeding and cardiovascular diseases and infant mortality. For maternal outcomes, a history of lactation was associated with a reduced risk of type 2 diabetes, breast, and ovarian cancer. Early cessation of breastfeeding or no breastfeeding was associated with an increased risk of maternal postpartum depression. There was no relationship between a history of lactation and the risk of osteoporosis. The effect of breastfeeding in mothers on return-to-prepregnancy weight was negligible, and the effect of breastfeeding on postpartum weight loss was unclear. EVIDENCE REPORT CONCLUSIONS A history of breastfeeding is associated with a reduced risk of many diseases in infants and mothers. Future research would benefit from clearer selection criteria, definitions of breastfeeding exposure, and adjustment for potential confounders. Matched designs such as sibling analysis may provide a method to control for hereditary and household factors that are important in certain outcomes.

Abstract
BACKGROUND Findings from observational studies suggest an inverse association between lactation and premenopausal breast cancer risk, but results are inconsistent, and data from large prospective cohort studies are lacking. METHODS We used information from 60,075 parous women participating in the prospective cohort study of the Nurses' Health Study II from 1997 to 2005. Our primary outcome was incident premenopausal breast cancer. RESULTS We ascertained 608 incident cases of premenopausal breast cancer during 357,556 person-years of follow-up. Women who had ever breastfed had a covariate-adjusted hazard ratio (HR) of 0.75 (95% confidence interval [CI], 0.56-1.00) for premenopausal breast cancer compared with women who had never breastfed. No linear trend was found with duration of total lactation (P = .95), exclusive lactation (P = .74), or lactation amenorrhea (P = .88). The association between lactation and premenopausal breast cancer was modified by family history of breast cancer (P value for interaction = .03). Among women with a first-degree relative with breast cancer, those who had ever breastfed had a covariate-adjusted HR of 0.41 (95% CI, 0.22-0.75) for premenopausal breast cancer compared with women who had never breastfed, whereas no association was observed among women without a family history of breast cancer. CONCLUSION In this large, prospective cohort study of parous premenopausal women, having ever breastfed was inversely associated with incidence of breast cancer among women with a family history of breast cancer.

Abstract
Breast cancer rates and median age of onset differ between Western Europe and North Africa. In Western populations, 5 to 10 % of breast cancer cases can be attributed to major genetic factors such as BRCA1 and BRCA2, while this attribution is not yet well defined among Africans. To help determine the contribution of BRCA1 mutations to breast cancer in a North African population, we analysed genomic DNA from breast cancer cases ascertained in Algiers. Both familial cases (at least three breast cancers in the same familial branch, or two with one bilateral or diagnosed before age 40) and sporadic cases less than 38 years of age were studied. Complete sequencing plus quantitative analysis of the BRCA1 gene was performed. 9.8 % (5/51) of early-onset sporadic and 36.4 % (4/11) of familial cases were found to be associated with BRCA1 mutations. This is in contrast 10.3 % of French HBOC families exhibiting a BRCA1 mutation. One mutation, c.798_799delTT, was observed in two Algerian families and in two families from Tunisia, suggesting a North African founder allele. Algerian non-BRCA1 tumors were of significantly higher grade than French non-BRCA tumors, and the age at diagnosis for Algerian familial cases was much younger than that for French non-BRCA familial cases. In conclusion, we observed a much higher frequency of BRCA1 mutations among young breast cancer patients than observed in Europe, suggesting biological differences and that the inclusion criterea for analysis in Western Europe may not be applicable for the Northern African population.

Abstract
PURPOSE Breast cancer remains the major malignant disease among Israeli women, with about 4,000 new cases diagnosed annually, and a steadily increasing incidence rates. Early in this century investigators noted that nulliparity and a history of never having breastfed were more common in women with breast cancer than without the disease. Epidemiological evidence on those issues remains controversial. The purpose of this study was to clarify those controversial. METHODS A hospital-based case control study was carried out at Nahariya hospital (North of Israel) to assess the risk of breast cancer in relation to breastfeeding history. A total of 256 recent cases of breast cancer (diagnosed between January 1999 and February 2005) and 536 controls were included. Detailed information regarding breastfeeding, menstruation, reproductive factors and confounders was collected. Adjusted odds ratios and 95% confidence intervals were calculated. RESULTS Short duration of lifetime breastfeeding, late age at first breastfeeding and experience of insufficient milk were found to increase breast cancer risk. When women who had ever breastfed their infants were compared with females who had not, breastfeeding was found to be protective (OR of 0.39; 95% CI 0.26-0.59). CONCLUSIONS These findings may have significant impact on intervention planning aimed towards breast cancer reduction among Israeli Jewish women.

Abstract
Background Studies show that when the Baby Friendly Hospital Initiative (BFHI) is implemented breastfeeding rates increase. However, there are likely to be various barriers to BFHI implementation. This article reports on an empirical study of government-directed BFHI implementation in the New Zealand public hospital system. It focuses primarily on the barriers encountered through implementing the first Two Steps of the BFHI: developing BFHI policy and communicating it to staff; and providing necessary staff training. Methods Qualitative interview data were collected from six lactation consultants. These interviewees emerged via a purposive sample of public hospitals that represent the full range of New Zealand public hospitals. Using a content analysis technique, key themes were drawn from the transcribed interview data. Results Analysis revealed eight themes: the hospitals were in varying stages of BFHI policy development; hospital policy was not necessarily based on government policy; hospital policies were communicated in differing ways and dependent on resources; factors outside of hospital control impacted on capacity to improve breastfeeding rates; and complex organisational matters pose a barrier to educating personnel involved in the birthing process. Conclusion The findings of this study provide empirical support for prior articles about the process of BFHI policy development and implementation. The study also shows that implementation is multi-faceted and complex.

Abstract
OBJECTIVE To determine the effects of a prenatal breastfeeding workshop on maternal breastfeeding self-efficacy and breastfeeding duration. DESIGN Randomized controlled trial. SETTING Large tertiary hospital in Ontario, Canada. PARTICIPANTS 110 primiparous women expecting a single child, an uncomplicated birth, and planning to breastfeed. INTERVENTION 2.5-hour prenatal breastfeeding workshop based on adult learning principles and self-efficacy theory. MAIN OUTCOME MEASURE Maternal breastfeeding self-efficacy and the numbers of days and amount of breastfeeding were measured at four and eight weeks postpartum. RESULTS/DATA ANALYSIS: Over time, maternal breastfeeding self-efficacy scores increased in both groups. Women who attended the workshop had higher self-efficacy scores and a higher proportion were exclusively breastfeeding compared to women who did not attend the workshop. There was little difference in the average number of days of breastfeeding, but the intervention group had less weaning. CONCLUSIONS The workshop increased maternal breastfeeding self-efficacy and exclusive breastfeeding.
