Sperm DNA fragmentation measured by Halosperm does not impact on embryo quality and ongoing pregnancy rates in IVF/ICSI treatments

Sperm DNA fragmentation (SDF) has been proposed to be one of the main markers regarding male infertility. A prospective study was performed to assess primarily whether sperm DNA damage has any impact on embryological data and secondarily on pregnancy rates. This prospective study evaluated the sperm DNA damage in fresh ejaculated sperm samples from couples undergoing IVF/ICSI treatments, using the improved SCD method, known as Halosperm^®. The results were evaluated by performing statistical analysis with the statistical package of SPSS v17. A total of 156 fresh semen samples derived from 156 couples undergoing 156 IVF/ICSI cycles. From the 156 couples, 139 finally reached the embryo transfer (ET) procedure. Overall, SDF did not correlate with embryological data, while ongoing pregnancy rate/ET was 21.6%. SDF only correlated with sperm characteristics. After the categorisation of SDF (≤35% and >35%), according to the specific references of the method used, embryological data were comparable as also ongoing pregnancy rates. Using the SCD method, sperm DNA damage is associated neither with embryological data nor to pregnancy rates. However, we should not rule out the fact that extremely high DNA damages are associated with total pregnancy failure.     

Effectiveness of manual lymphatic drainage vs. perineal massage in secundigravida women with gestational oedema: A randomised clinical trial

Perineal trauma (PT) may be considered as a very common injury during the childbirth. The incidence of PT was estimated in 30% to 85%, with 60% to 70% requiring suture. The present study was a prospective, single‐blinded, randomised, clinical trial carried out from January 2015 to January 2016. For this study, 49 secundigravida women diagnosed with gestational oedema were recruited and randomly divided into two groups (A and B). Group A (n = 30) received the conventional treatment plus perineal massage and group B (n = 19) the conventional treatment plus manual lymphatic drainage (MLD). Visual analogue scale (VAS) and King Health's Questionnaire (KHQ) were performed to assess pain intensity and quality of life‐related with urinary incontinence (UI). Pain intensity measurements showed statistically significant differences for a decrease after 30‐weeks (P = .037), after 36‐weeks (P = .000), and at the end of puerperium (P = .014) for MLD with respect to perineal massage group. Moreover, inter‐groups repeated measures ANOVA for the values related statistically significant differences to the interaction of each applied treatment (perineal massage and MLD group, separately) over the pain intensity variable. MLD treatment reduced pain intensity with respect to perineal massage in secundigravida women with gestational oedema from 25‐weeks of gestation to the end of puerperium.     

Live birth after cervical ectopic uterus transplantation in mice

An ideal animal model is a prerequisite for the basic research of uterus transplantation. This study aimed to develop a new cervical ectopic uterus transplantation mice model, which was established by vascular anastomosis of the right common iliac artery and vein of the donor with the right common carotid artery and external jugular vein of the recipient, respectively, using the cuff method. The survival status of the transplanted uterus was assessed by macroscopic observation and histological examination after surgery, and the function of the graft uterus was tested by verifying whether the pregnancy is possible. A total of 40 transplants were performed, of which only 1 failed due to donor hemorrhage. After 26 transplants, the total operation time reduced to 52.4 ± 3.8 minutes, of which the total ischemia time took 6.6 ± 1.1 minutes. Sixty days after transplantation, all the graft uteri had a good blood supply and spontaneous contraction. The histology showed no significant difference between the transplanted uterus and the native. Embryo transfer experiments have proven that the transplanted uterus has uterine function. In conclusion, this new model is an effective and simple mice model for the studies of the scientific issues related to uterus transplantation.     

Airway management for neonates requiring ex utero intrapartum treatment (EXIT)

In utero congenital malformations in the fetus can occasionally lead to an obstructed airway at birth accompanied by hypoxic injury or peripartum demise, without intervention. Ex utero intrapartum treatment (EXIT) may help reduce morbidity and mortality associated with challenging airways by providing extra time on uteroplacental circulation to secure the airway. Meticulous preparation and planning are crucial for this procedure. Many different types of congenital malformations can result in a difficult airway, but there is no correlation between specific malformations and a required type of airway intervention. Based on our experience and literature review, an airway process flow diagram has been created to help assist teams in decision‐making for airway intervention in a neonate during the EXIT procedure. The management of the airway in this scenario involves additional unique considerations that accompany handling a partially delivered newborn in the uterine environment. Extensive preparation and team rehearsal are essential to the success of this procedure.
