Objective: To investigate the use of non-barrier contraceptives among women with HIV (WWH) compared to women from the general population (WGP) in Denmark.

Design: Nationwide population-based matched cohort study.

Methods: We included WWH aged 16-50, treated at an HIV specialized clinic, and included in The Danish HIV Cohort Study between 1995-2021 and an age-matched comparison cohort of WGP.

Objective: To study the association between sperm deoxyribonucleic acid fragmentation index (DFI) and the odds of preeclampsia and other adverse perinatal outcomes after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatment.

Design: A prospective cohort study including infertile couples undergoing conventional IVF or ICSI treatment and their children. Data regarding preeclampsia and perinatal outcomes were derived from the Swedish National Birth Register.

Introduction: Today, it is widespread practice to postpone frozen embryo transfer (FET) in a modified natural cycle (mNC) for at least one menstrual cycle after oocyte retrieval and failed fresh embryo transfer or freeze-all. The rationale behind this practice is the concern that suboptimal ovarian, endometrial or endocrinological conditions following ovarian stimulation may have a negative impact on endometrial receptivity and implantation. However, two recent systematic reviews and meta-analyses based on retrospective data did not support this practice.

Gonadotropin-releasing hormone agonist (GnRHa) for final oocyte maturation, along with vitrification of all usable embryos followed by transfer in a subsequent frozen-thawed cycle, is the most effective strategy to avoid ovarian hyperstimulation syndrome (OHSS). However, less is known about the ovulation induction triggers effect on early embryo development and blastocyst formation. This study is a secondary analysis of a multicenter, randomized controlled trial, with the aim to compare embryo development in normo-ovulatory women, randomized to GnRHa or human chorionic gonadotropin (hCG) trigger.

Night work has been associated with sleep disorders as well as cardiovascular, endocrinologic, metabolic and immunological disturbances as shown in this review. Several night shifts in a row and more than one night shift per week is associated with increased risk of pregnancy-related complications. A dose-response pattern has been shown between the number of night shifts during pregnancy and the risk of miscarriage, hypertensive disorders and sick leave.

Article Synopsis
  • The study examines how the mode of delivery (cesarean vs. vaginal) affects the risk of affective disorders in children, considering the gut microbiota's role.
  • It analyzed data from over a million Danish children, finding a small increased risk of affective disorders for those born via cesarean sections, especially during intrapartum delivery.
  • However, when comparing siblings, the association for pre-labor cesarean disappeared, suggesting that while there may be a correlation, delivery mode likely isn't a direct cause of these disorders.

Due to the necessity of iron for a variety of cellular functions, the developing mammalian organism is vulnerable to iron deficiency, hence causing structural abnormalities and physiological malfunctioning in organs, which are particularly dependent on adequate iron stores, such as the brain. In early embryonic life, iron is already needed for proper development of the brain with the proliferation, migration, and differentiation of neuro-progenitor cells. This is underpinned by the widespread expression of transferrin receptors in the developing brain, which, in later life, is restricted to cells of the blood-brain and blood-cerebrospinal fluid barriers and neuronal cells, hence ensuring a sustained iron supply to the brain, even in the fully developed brain.

Objective: The aim of our study was to investigate the acute effect of night work during pregnancy on the risk of calling in sick the following day using register-based information and the workers as their own controls.

Methods: Using the payroll-based national Danish Working Hour Database, including all public hospital employees in Denmark, we identified 9799 pregnant women with ≥1 day shift and ≥1 night shift and ≥1 day of sick leave during the first 32 pregnancy weeks from January 2007 to December 2013. We performed fixed effects logistic regression, that is, within-worker comparisons, of the risk of sick leave of any duration starting within 24 hours after night shifts of different length versus day shifts.

Hypertension during pregnancy is one of the leading causes of maternal and foetal morbidity and mortality. Monitoring of blood pressure is therefore an essential part of prenatal care. Masked hypertension, where blood pressure levels are elevated at home despite normal blood pressure levels monitored in a clinical setting, may lead to cardiovascular and obstetric complications equal to those of sustained hypertension.

Background: In high-income countries, a healthy diet is widely accessible. However, a change toward a poor-quality diet with a low nutritional value in high-income countries has led to an inadequate vitamin intake during pregnancy.

Objective: We conducted a systematic review and meta-analysis to evaluate the association between multivitamin use among women in high-income countries and the risk of adverse birth outcomes (preterm birth [primary outcome], low birthweight, small for gestational age, stillbirth, neonatal death, perinatal mortality, and congenital anomalies without further specification).

Women who get pregnant after infertility treatment differ from women with naturally conceived pregnancies concerning prenatal screening: on average they are older and therefore they have a greater risk of carrying a child with Down's syndrome, their children have an increased risk of congenital malformations, and they have a great wish to avoid invasive prenatal diagnostic tests. The conclusion of this review is that first trimester screening is an acceptable choice for these women, although larger studies are needed to clarify whether a correction factor is necessary for the biochemical markers.
