Diagnosed with a concussion, he exited the game and the rest of the season on the orders of his doctor and hockey coach and spent the following weeks on the bench wrestling with a nagging question: how long would it take to fully recover? In this global market, clubs must maintain or improve fans’ attendance at the stadium; simultaneously, they need, more than ever, to take care of social media. The football club market is changing fast in the social media era. Moreover, metformin therapy during pregnancy in PCOS women was found to result in reduced incidence of GDM and shown not to have any adverse effect on infant’s birth weight, height, and motor and social development at 3 and 6 months of life. They found no evidence for use of metformin throughout all trimesters to reduce pregnancy complications in PCOS women. Khattab, et al. compared the incidences of GDM and preeclampsia in PCOS women continuing metformin throughout pregnancy with that of those who discontinued metformin use at the time of conception. The third ESHRE/ASRM-sponsored PCOS consensus workshop on women’s health aspects of PCOS recommended that there is no evidence for improved live-birth rates or decreased pregnancy complications with the use of metformin either before conception or during pregnancy.

There is still insufficient evidence for use of metformin during pregnancy. There was statistically significant reduction in the incidence of GDM (OR 0.17) and preeclampsia (OR 0.35) in favor of group continuous metformin throughout pregnancy. There was no difference in fetal birth weight between the groups. Women in the metformin group gained less weight during pregnancy compared with those in the placebo group. There were no differences between the metformin and placebo groups in the primary outcome of the prevalence of preeclampsia, preterm delivery, GDM, or the composite of these three pregnancy complications. Insulin resistance, both intrinsically and that due to superimposed obesity, forms the most important pathogenetic mechanism for PCOS complications. Eng, et al. demonstrated that metformin activates AMP kinase (AMPK) directly improving insulin signaling within the blastocyst, leading to improved pregnancy outcomes. The GSTT1 null genotype was not found to be a risk factor for pregnancy loss in the pooled population but its association with RPL was found in the Indian population.

Meta-analysis on the polymorphisms was conducted to support our findings that the presence of mutant genotypes at this site increases the risk of pregnancy loss. In a meta-analysis study, the presence of the GSTM1 null genotype was shown to be a risk for RPL. Palomb,a et al. evaluated the effect of pregestational metformin administration on miscarriage risk in PCOS women by conducting a systematic review of randomized controlled trials till date and carrying out subsequent meta-analysis. They concluded that metformin has no effect on the miscarriage risk in PCOS women when administered before pregnancy. This study suggests that women carriers of GSTT1 and GSTM1 null genotypes are more often at genetic risk of pregnancy loss. In a case-control study, 174 early pregnancy loss (EPL) patients, of which 130 were recurrent pregnancy loss (RPL) patients, and 180 healthy controls were investigated. Glueck, et al. documented the benefit of metformin for reducing EPL in an initial pilot study of PCOS women comparing with that of historic controls.

Vanky, et al. initially did a pilot study on metformin’s utility in pregnancy of PCOS women, which showed a reduced rate of severe pregnancy complications when it was taken throughout pregnancy. They later followed it up with a randomized, 토토 메이저사이트 placebo-controlled, double-blind, multicenter study to investigate the effect of metformin on pregnancy complications and pregnancy outcome in PCOS women. It therefore seems logical to treat PCOS complications with insulin sensitizers. Metformin is the commonly used insulin sensitizer. In the recent Metformin in Gestational Diabetes (MIG) trial comparing metformin and insulin treatment in GDM, there was no significant difference in the composite fetal outcome between the metformin and insulin groups. The use of metformin for control of glucose intolerance in PCOS remains a controversial issue. Currently, metformin has been recognized by FDA as a class B for use in pregnancy, which means that either animal-reproduction studies have not shown a fetal risk without corresponding controlled studies in women, or animal studies have shown an adverse effect not confirmed by controlled studies in women. Although the safety of metformin for fetus in pregnancy has been documented in many studies, its use in pregnancy persists to be a contentious issue. In the circumstance of PCOS woman becoming pregnant while being on metformin therapy, it would be advisable to stop metformin once pregnancy is confirmed.
