The link between maternal obesity and inflammatory mediators is still unclear. Our aim was to summarize the main findings of recently published studies on this topic. We performed a search in Medline for studies published in the last years on obesity, human pregnancy, and inflammatory mediators. We report the findings of 30 studies. The characteristics and number of participants, study design, gestational age at sample collection, and type of sample varied widely. Approximately two-thirds of them investigated more than one mediator, and 50% included participants in only one trimester of pregnancy. The most frequently investigated mediators were leptin, tumour necrosis factor-alpha (TNF-α), and interleukin (IL)-6. Almost all studies reported an association between maternal obesity, leptin, and C-reactive protein (CRP) serum levels but not with IL-1β and IL-10. The association of IL-6, TNF-α, monocyte chemo-attractant protein-1 (MCP-1), adiponectin, and resistin with maternal obesity is still controversial. To clarify the physiopathological link between maternal obesity and inflammation, more high-quality studies are needed., (© 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Problem: Our study aimed to assess in vitro production of IL-10, IL-6, TNF-A, and adiponectin serum levels in pregnant women with and without gestational diabetes mellitus (GDM) and to investigate a possible association between GDM and IL-10-1082 A>G (rs1800896), IL-6-174 G>C (rs1800795), TNF-A-308 G>A (rs1800629), adiponectin +45 T>G (rs2241766), and adiponectin-11377 C>G (rs266729) gene polymorphisms., Method of Study: This case-control study included 79 women with GDM and 169 healthy controls (C) grouped according to pre-pregnancy BMI. IL-10, IL-6, and TNF-A culture supernatant and adiponectin serum levels were assessed by ELISA. DNA genotype was performed by PCR-RFLP., Results: Adiponectin levels were significantly higher in C than GDM women, even within the same BMI category. Cytokines levels were similar between the groups. There were no associations between GDM and the analyzed gene polymorphisms., Conclusions: Women with GDM have significantly lower adiponectin levels in the third trimester, regardless of BMI., (© 2011 John Wiley & Sons A/S.)

Objectives: To examine the association between high prepregnancy maternal body mass index (BMI) and the risk of preterm birth (PTB)., Methods: A systematic review of the literature. We included cohorts and case-control studies published since 1968 that examined the association between BMI and PTB of all types, spontaneous (s), elective and with ruptured membranes (PPROM) in three gestational age categories: general (<37 weeks), moderate (32-36 weeks) and very (<32 weeks) PTB., Results: 20,401 citations were screened and 39 studies (1,788,633 women) were included. Preobese (BMI, 25-29.9) and obese I (BMI, 30-34.9) women have a reduced risk for sPTB: AOR = 0.85 (95% CI: 0.80-0.92) and 0.83 (95% CI: 0.75-0.92), respectively. Their risk for moderate PTB was 1.20 (95% CI: 1.04-1.38) and 1.60 (95% CI: 1.32-1.94), respectively. Obese II women (BMI, 35-40) have an increased risk for PTB in general (AOR = 1.33, 95% CI: 1.12-1.57) moderate (AOR = 2.43, 95% CI: 1.46-4.05) and very PTB (AOR = 1.96, 95% CI: 1.66-2.31). Obese III women (BMI > 40) have an even higher risk for very PTB (AOR = 2.27, 95%CI: 1.76-2.94). High BMI does not modify the risk for PPROM and increases the risk for elective PTB., Conclusions: High maternal BMI may have different effects on different types of PTB.

Obesity and gestational diabetes mellitus (GDM) are increasing worldwide and may compromise female sexual function. We hypothesize that among GDM patients in the third trimester of pregnancy, those with excess body fat would have worse female sexual function scores than normal weight women. Our aim was to assess the sexual function of overweight compared to normal weight women with GDM. This was a cross-sectional survey involving 143 Brazilian women with GDM in the third trimester of pregnancy: 76 were overweight (pre-pregnancy body mass index-BMI≥25.0 Kg/m2) and 67 were normal weight (BMI 18.5–24.9 Kg/m2). Participants were recruited from March 2010 to April 2013 at the antenatal clinic of a single public tertiary teaching institution. The Female Sexual Function Index (FSFI) questionnaire was used to assess sexual function. Overall, 51.7% of the 143 participants were at risk for sexual dysfunction symptoms (FSFI scores ≤26); this rate was significantly higher among overweight compared to normal weight women (60.5% versus 41.8%, p = 0.038). Mean total FSFI scores were significantly lower in overweight compared to normal weight women (21.7±9.2 versus 24.9±8.0, p = 0.029). Compared to normal weight women, overweight participants had lower mean scores in desire (3.4±1.2 versus 4.0±1.4, p = 0.007) and lubrication (3.8±2.0 versus 4.5±1.6, p = 0.023). According to these results, overweight women with GDM in the third trimester of pregnancy have lower female sexual function scores than normal weight women with the same disorder.

ABSTRACT Introduction. The number of women with gestational diabetes mellitus (GDM) is growing worldwide in parallel with the obesity epidemic. The diagnosis of GDM leads to substantial modifications in the daily routine of these women, and these adjustments could potentially affect their sexual function. There are no previous studies on the sexual function of patients with GDM. Aim. The aim of this study was to investigate the sexual function of patients with GDM in comparison with healthy pregnant women at the same gestational age. Methods. Brazilian women in the third trimester of pregnancy with and without GDM were invited to participate in this cross-sectional study while waiting for their antenatal care visits at a single public tertiary teaching institution between March and December 2010. The Brazilian version of the Female Sexual Function Index (FSFI) questionnaire was used to assess sexual function. Main Outcome Measures. Desire, arousal, lubrication, orgasm, sexual satisfaction, and pain during and after coitus in the last 4 weeks, measured according to a standardized and validated questionnaire. Results. A total of 87 participants were enrolled (43 healthy women and 44 with GDM). There were no significant differences in the sociodemographic characteristics of both groups. The total FSFI scores of GDM patients was 21.0 ± 9.59 compared with 22.3 ± 9.17 for healthy women ( P = 0.523). Difficulty in desire was the most common sexual dysfunction symptom in both groups, being reported by 42% and 50% of GDM and healthy women, respectively ( P = 0.585). Conclusion. The sexual function of Brazilian patients with GDM does not differ significantly from that of healthy pregnant women at the same gestational age.
