Posttraumatic stress disorder is a prolonged stress and anxiety response that occurs after exposure to a traumatic event. Research shows that both parental and child posttraumatic stress symptoms (PTSS) are correlated but parental executive functions (EFs) could buffer this link. EFs refers to a group of high-level cognitive processes that enable self-regulation of thoughts and actions to achieve goal-directed behaviours and can be of importance for both positive parenting interactions and effective coping skills for PTSS.

Crying is a typical infant behavior that activates parental caregiving behaviors, acting as "human alarms" important for the infant's survival. When living under war-related threat, the auditory system may be sensitized given its importance for survival, potentially impacting maternal cry processing. Children living in armed-conflict zones are at increased risk for behavior problems, which may relate to both direct exposure and indirect effects through their parents' perceptions and behaviors.

Objective: This study was aimed to assess the association between ovarian hyperstimulation syndrome (OHSS) and pregnancy complications among women who conceived following fertility treatment.

Study Design: A retrospective population-based cohort study, including all singleton deliveries of patients conceived following ovulation induction (OI) or in vitro fertilization (IVF) between 1988 and 2016, was conducted. All births occurred in a single tertiary medical center.

Purpose: Endometrial scratching (ES) using a biopsy catheter prior to the IVF cycle in the repeated implantation failure (RIF) population has been suggested, but no convincing evidence of its benefit has been presented until now.

Methods: A retrospective mono-center study among 300 consecutive IVF-RIF cycles following evaluation of the ovarian reserve, hysterosalpingography or hysteroscopy, pelvic ultrasound, thrombophilia evaluation, karyotyping and assessment of male sperm parametrs. The findings within normal limits.

Klinefetter syndrome is one of the most common genetic causes of male infertility and the most common cause of primary testicular failure. Beside the infertility issue, the syndrome causes decreases in bone mass, muscle wasting, decline in cognitive ability and increases the risk of diseases such as diabetes mellitus, cancer and cardiovascular diseases. Most men are diagnosed late when fertility problems arise and some even remain undiagnosed.

We introduce a three-phase, nine-step methodology for specification of clinical guidelines (GLs) by expert physicians, clinical editors, and knowledge engineers and for quantitative evaluation of the specification's quality. We applied this methodology to a particular framework for incremental GL structuring (mark-up) and to GLs in three clinical domains. A gold-standard mark-up was created, including 196 plans and subplans, and 326 instances of ontological knowledge roles (KRs).

Clinical guidelines are a major tool in improving the quality of medical care. However, to support the automation of guideline-based care, several requirements must be filled, such as specification of the guidelines in a machine-interpretable format and a connection to an Electronic Patient Record (EPR). For several different reasons, it is beneficial to convert free-text guidelines gradually, through several intermediate representations, to a machine-interpretable format.

Objective: To determine maternal and neonatal complications among dichorionic and monochorionic twins with isolated midtrimester elevated maternal serum human chorionic gonadotropin (MShCG).

Material And Methods: MShCG was determined in 247 women with dichorionic twins and 32 women with monochorionic twins between 16-18 weeks gestation. Among the dichorionic twins 219 patients had MShCG < 2.

Background: In vitro fertilization and embryo transfer has become a common therapeutic modality in modern fertility medicines. Treatment protocols are associated with exaggerated hormonal fluctuations in order to promote multiple follicular development and support of embryo survival. Estrogen is considered to be closely linked to migraine, and its extreme serum level fluctuations have been considered to trigger migrainous headaches.
