Children and adolescents weathering the storm: Resilience in the presence of bullying victimization, harassment, and pandemic lockdown in northern Norway.

Resilience is a concept of growing interest because it can systematically inform prevention measures and psychosocial interventions for children and adolescents. The aim of this study was to explore resilience factors among young people who are victims of bullying and harassment (age 9 to 16 years old). In 2021 the burden of the pandemic lockdown became an additional adversity.

Setting: Fertility centers.

High-sensitivity C-reactive protein levels and pregnancy outcomes in women with unexplained infertility after ovarian stimulation with intrauterine insemination in a multicenter trial.

Objective: To determine if chronic inflammation, assessed by basal high-sensitivity C-reactive protein (hs-CRP) levels, is associated with pregnancy outcomes in women with unexplained infertility undergoing ovarian stimulation with intrauterine insemination.

Design: Prospective cohort analysis of the Reproductive Medicine Network's Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS) randomized controlled trial.

Setting: Multicenter university-based randomized controlled trial.

A personalized medicine approach to ovulation induction/ovarian stimulation: development of a predictive model and online calculator from level-I evidence.

Objective: To estimate the probability of clinical or multiple pregnancy during ovulation induction (OI)/ovarian stimulation (OS).

Design: Secondary analysis of two multicenter randomized clinical trials (combined).

Setting: Multicenter.

Biomarkers of Stress and Male Fertility.

To study if stress, as measured by salivary alpha-amylase and cortisol, negatively impacts male fertility, as measured by semen parameters, pregnancy, and live birth rates. Prospective, cohort study of men enrolled in the Males, Antioxidants, and Infertility (MOXI) trial. One-hundred twelve infertile men provided first-morning salivary and semen samples at baseline.

Effects of preconception lifestyle intervention in infertile women with obesity: The FIT-PLESE randomized controlled trial.

Background: Women with obesity and infertility are counseled to lose weight prior to conception and infertility treatment to improve pregnancy rates and birth outcomes, although confirmatory evidence from randomized trials is lacking. We assessed whether a preconception intensive lifestyle intervention with acute weight loss is superior to a weight neutral intervention at achieving a healthy live birth.

Methods And Findings: In this open-label, randomized controlled study (FIT-PLESE), 379 women with obesity (BMI ≥ 30 kg/m2) and unexplained infertility were randomly assigned in a 1:1 ratio to 2 preconception lifestyle modification groups lasting 16 weeks, between July 2015 and July 2018 (final follow-up September 2019) followed by infertility therapy.

Natural vs. programmed cycles for frozen embryo transfer: study protocol for an investigator-initiated, randomized, controlled, multicenter clinical trial.

Background: Randomized trials of assisted reproductive technology (ART) have been designed for outcomes of clinical pregnancy or live birth and have not been powered for obstetric outcomes such as preeclampsia, critical for maternal and fetal health. ART increasingly involves frozen embryo transfer (FET). Although there are advantages of FET, multiple studies have shown that risk of preeclampsia is increased with FET compared with fresh embryo transfer, and the reason for this difference is not clear.

Sperm deoxyribonucleic acid fragmentation: predictors, fertility outcomes, and assays among infertile males.

Objective: To examine the factors associated with increased deoxyribonucleic acid fragmentation index (DFI), evaluate the pregnancy outcomes of men with increased DFI, and compare three independent DFI assays.

Design: Secondary analysis.

Setting: Nine US-based fertility centers.

The relationship of plasma antioxidant levels to semen parameters: the Males, Antioxidants, and Infertility (MOXI) randomized clinical trial.

Purpose: The understanding of the role of plasma antioxidant levels in male fertility in the USA is limited. In a secondary analysis of the Males, Antioxidants, and Infertility (MOXI) randomized clinical trial, we sought to determine whether serum levels of vitamin E (α-tocopherol), zinc, and selenium were correlated with semen parameters and couple fertility outcomes.

Methods: This study is a secondary analysis of the MOXI clinical trial.

Relationship between semen regurgitation and pregnancy rates with intrauterine insemination.

Objective: To evaluate the relationship between semen regurgitation and intrauterine insemination (IUI) outcomes. We hypothesized that clinical pregnancy rates and live birth rates would be reduced when regurgitation occurred.

Design: Retrospective cohort study.

Effect of an Active vs Expectant Management Strategy on Successful Resolution of Pregnancy Among Patients With a Persisting Pregnancy of Unknown Location: The ACT or NOT Randomized Clinical Trial.

Importance: Women with an early nonviable pregnancy of unknown location are at high risk of ectopic pregnancy and its inherent morbidity and mortality. Successful and timely resolution of the gestation, while minimizing unscheduled interventions, are important priorities.

Objective: To determine if active management is more effective in achieving pregnancy resolution than expectant management and whether the use of empirical methotrexate is noninferior to uterine evacuation followed by methotrexate if needed.

Sleep Habits of Women With Infertility.

Context: Sleep plays important roles in metabolic and reproductive function, and polycystic ovary syndrome (PCOS) is associated with sleep disturbances, including increased prevalence of obstructive sleep apnea.

Objective: We sought to evaluate sleep parameters in infertile women with PCOS compared with women with unexplained infertility (UI) and identify risk factors for disturbed sleep.

Methods: At private and academic ambulatory gynecology and infertility practices, we evaluated a prospective cohort of women diagnosed with PCOS or UI from 2 randomized clinical trials.
