Endometriosis and uterine malformations: infertility may increase severity of endometriosis.

INTRODUCTION: The aim of our study was to compare the stage and severity of endometriosis in fertile and infertile women with congenital uterine malformations. MATERIAL AND METHODS: We performed an observational study from September 2007 to December 2015 in a tertiary care university hospital and assisted reproductive technology center. A total of 52 patients with surgically proven uterine malformations were included. We compared 41 infertile patients with uterine malformations with 11 fertile patients with uterine malformation. The main outcome was the stage, score and type of endometriosis in regard to infertility and class of uterine malformation. RESULTS: The rate of endometriosis did not differ between the two groups (43.9 vs. 36.4%). The mean revised American Fertility Society score was higher in infertile patients with uterine malformations (19.02 vs. 6, p < 0.05). No significant difference was found in the rate of superficial peritoneal endometriosis (43.9 vs. 37.5%). Endometrioma and deep infiltrating endometriosis were associated with uterine malformations in infertile women, respectively 14.6 and 0%. No difference in the characteristics of endometriosis was found regarding the class of malformation. CONCLUSIONS: The association of uterine malformations and infertility may increase the severity of endometriosis and raise the issue of their diagnosis and management.

Relationship between vitamin D status in the first trimester of pregnancy and gestational diabetes mellitus - A nested case-control study.

BACKGROUND & AIMS: Gestational diabetes mellitus (GDM) is one of the most frequent medical complications during pregnancy. It has been associated with many adverse pregnancy, fetal and neonatal outcomes, as well as with an increased risk for mothers and children in the long term. There is a growing interest in vitamin D and its potential role in the development of metabolic disorders. However, the medical literature is not consensual. The aim of this study was to assess the risk of GDM according to vitamin D status during the first trimester. METHODS: This study is a nested case-control study performed from a multicenter prospective observational cohort of pregnant women assessed for 25-hydroxyvitamin D levels (25OHD). Three hundred ninety-three patients were included in the initial cohort. After applying exclusion criteria, a total of 1191 pregnant women were included. Two hundred fifty women with GDM (cases) were matched to 941 women without GDM (controls) for parity, age, body mass index before pregnancy, the season of conception, and phototype. This study was funded by a grant from the "Programme Hospitalier de Recherche Publique 2010". RESULTS: The GDM risk was significantly greater for patients with 25OHD levels <20 ng/mL (OR = 1∙42, 95% CI 1∙06-1∙91; p = 0∙021). However, there was no significant relationship with other thresholds. The study of 25OHD levels with the more precise cutting of 5 units intervals showed a variable relationship with GDM risk, as the risk was low for very low 25OHD levels, increased for moderated levels, decreased for normal levels, and finally increased for higher levels. CONCLUSION: According to our study, there seems to be no linear relationship between GDM and 25OHD levels in the first trimester of pregnancy since GDM risk does not continuously decrease as 25OHD concentrations increase. Our results most probably highlight the absence of an association between 25OHD levels and GDM risk.

[Physical activity after breast cancer diagnosis and survival: A systematic review]. / Activité physique après diagnostic de cancer du sein et survie : revue de la littérature.

INTRODUCTION: The benefits of physical activity (PA) in breast cancer are currently recognized in primary prevention. The World Cancer Research Fund (WCRF) and then the National Cancer Institute (INCa) have reported conflicting results regarding the impact of post-diagnosis PA on breast cancer outcomes. The aim of this systematic review is to assess the association between PA after breast cancer diagnosis and overall mortality, specific mortality and risk of breast cancer recurrence in the literature. METHODS: Randomized trials, prospective cohorts and meta-analyses studying post-diagnosis PA and overall mortality, breast cancer mortality or risk of recurrence after breast cancer published between January 1, 2014 and October 1, 2019 were included. The articles selected by the INCa report prior to 2014 were included in the literature review. RESULTS: Eighteen articles have been selected. Studies unanimously concluded that overall mortality was reduced by post-diagnosis PA practice. For specific mortality, 5 meta-analyses showed a significant decrease in breast cancer mortality and 2 found a decrease in the risk of recurrence. CONCLUSION: Post-diagnosis PA reduces overall mortality and appears to impact specific breast cancer mortality and risk of recurrence. However, these results need to be confirmed by larger randomized trials.

Vitamin D and pregnancy outcomes: Overall results of the FEPED study.

Vitamin D insufficiency is highly prevalent in children and adults including pregnant women. During pregnancy, maternal vitamin D insufficiency could increase risks of several pregnancy complications and adverse birth outcomes. The FEPED study was designed to assess the effects of maternal vitamin D status in the first trimester during pregnancy on risks of preeclampsia, gestational diabetes mellitus (GDM), preterm birth and small-for-gestational age (SGA) at birth. This observational prospective cohort included 3129 women with a singleton pregnancy between April 2012 and July 2014 in six maternity units in France and Belgium. The aim of this review is to summarize the results of the FEPED study. At the first trimester the mean 25(OH)D concentration was 21.9 ± 10.4 ng/mL and 25(OH)D concentration was <20 ng/mL in 46.5 % of patients. After matching 83 cases of preeclampsia with 319 controls, a significant decrease in the risk of preeclampsia was associated with maternal vitamin D levels ≥ 30 ng/mL in the third trimesters (OR = 0.34; 95 % CI: 0.13-0.86. P = 0.023). In the first trimester, the risk for preeclampsia was decreased in these patients, but did not achieve statistical significance (OR = 0.57 95 % CI, 0.30-1.01; p = 0.09). For the 250 cases with GDM matched with 941 controls, no linear relationship was found between GDM and 25OHD levels in the first trimester of pregnancy. Finally, 2813 pregnant women were included in analyses of risks of preterm and SGA birth. No association was found between low maternal vitamin D levels in the first trimester and the risks of preterm birth (aOR = 1.53; 95 % CI: 0.97-2.43) or SGA (aOR = 1.07; 95 % CI: 0.75-1.54). Further investigation is needed to understand the mechanisms behind the association between vitamin D and birth outcomes.

[Desire for pregnancy and breast cancer]. / Désir de grossesse et cancer du sein.

Breast cancer affects about 3,000 new women of childbearing age each year. The desire for pregnancy is therefore a frequent issue in the management of breast cancer. We reviewed the current state of knowledge and recommendations in high-risk women, on the consideration of this desire for pregnancy in therapeutic management, the way to approach it, the preservation of fertility in the care process and finally on the outcomes of pregnancy after breast cancer. We evaluated the desire for pregnancy, qualitatively and quantitatively, after breast cancer through a literature review.
