Filter by:Investigators will be comparing artificial (HRT) frozen-thawed embryo transfer cycles to correctly conducted spontaneous natural cycles after the transfer of a chromosomally normal embryo.
Physiological changes necessitate the use of pregnancy-specific reference ranges for TSH and FT4 to diagnose thyroid dysfunction during pregnancy. Although many centers use fixed upper limits for TSH of 2.5 or 3.0 mU/L, this may lead to overdiagnosis or even overtreatment. The new guidelines of the American Thyroid Association have considerably changed recommendations regarding thyroid function reference ranges in pregnancy accordingly. Any hospital or physician that is still using the 2.5 or 3.0 mU/l cut-off for TSH during pregnancy should evaluate their own lab-specific cut-offs. The investigator's objective is to establish a rational reference range of serum TSH for diagnosis of subclinical hypothyroidism in the first and second trimester of pregnant women in west Black Sea region in Turkey.
The effects of vitamin D2 supplement during pregnancy on postpartum maternal and fetal vitamin D levels: the randomized controlled trial
This study evaluates the effects of essential oils on nausea, vomiting, and quality of life scores among pregnant women. Participants will receive either an essential oil roll-on product or a placebo product to apply to their temples and jaw line daily for 6 days.
In a randomized multicenter trial the investigators want to compare the ability of two hCG-based models in correctly classifying EPs as high risk among PULs and correctly classifying IUPs and failed PULs as low risk after two hCG measurements. After the classification of PULs into high or low risk of EP, the clinical management will be the same within each risk group (high and low) regardless of randomization group (which model classified the patients). The clinical management will be according to the management protocol published in a NICE guideline.
The purpose as well as the aim of this project is to understand the effect of probiotics on gastrointestinal (GI) dysfunction such as nausea, vomiting, and constipation that are found during the first and second trimesters of pregnancy. The primary objective of this project is to uncover whether probiotics have an effect on GI functional disorders. The secondary objective is to identify the microbiota associated with probiotic intake. The tested hypothesis is that gut microbiota influences the GI functions and may influence constipation, nausea, and vomiting during pregnancy.
This study tested the extent to which TOP®, when replicated with fidelity, produced impacts on sexual risk-taking behaviors in the short term and the longer term.
