Chromatin remodeler CHD8 is required for spermatogonial proliferation and early meiotic progression.

Meiosis is a key step during germ cell differentiation, accompanied by the activation of thousands of genes through germline-specific chromatin reorganization. The chromatin remodeling mechanisms underpinning early meiotic stages remain poorly understood. Here we focus on the function of one of the major autism genes, CHD8, in spermatogenesis, based on the epidemiological association between autism and low fertility rates.

Plasma cytokine and growth factor response to acute psychosocial stress in major depressive disorder.

Background: Pro-inflammatory cytokines such as interleukin (IL)-6 and tumor necrosis factor (TNF)-α are elevated in response to psychosocial stress; however, less is known about other inflammatory markers.

Methods: We explored response to the Trier Social Stress Test (TSST) of 16 cytokines and growth factors in patients with major depressive disorder (MDD, n = 12) vs. healthy volunteers (HV, n = 16).

Laser vaporization of the cervix is associated with an increased risk of preterm birth and rapid labor progression in subsequent pregnancies.

Purpose: Laser vaporization of the cervix is an established method of treating cervical intra-epithelial neoplasia, but its effect on subsequent pregnancies remains controversial. The aim of this study was to investigate pregnancy outcomes after laser vaporization.

Methods: We conducted a retrospective study involving women who delivered live singletons between 2012 and 2019 in a tertiary hospital.

Maternal characteristics and neonatal outcomes of emergency repeat caesarean deliveries due to early-term spontaneous labour onset.

Background: The optimal timing of elective repeat caesarean delivery has yet to be determined. One of the reasons to schedule an elective repeat caesarean delivery before 39 weeks gestation is to avoid emergency caesarean delivery due to spontaneous onset of labour.

Aims: By ascertaining maternal characteristics and neonatal outcomes associated with early-term onset of spontaneous labour, we aim to determine the optimal timing for each individual repeat caesarean delivery.

Intrathoracic shunt displacement with massive pleural effusion after successful shunt placement in a hydropic fetus with multilocular macrocystic congenital pulmonary airway malformation.

We successfully performed shunting for a fetus with a multilocular macrocystic lung mass with hydrops at 22 weeks' gestation. Complete resolution of hydrops was achieved; however, at 35 weeks' gestation, the fetus developed acute massive pleural effusion. Fetal ultrasound examination revealed that one end of the shunting tube had migrated downward in the thoracic cavity, which led to fluid draining from the lung cyst.
