REVIEW
Marion Kibuka, Jim G Thornton
BACKGROUND: Epidural analgesia for pain relief in labour prolongs the second stage of labour and results in more instrumental deliveries. It has been suggested that a more upright position of the mother during all or part of the second stage may counteract these adverse effects. This is an update of a Cochrane review first published in 2013. OBJECTIVES: To assess the effects of different birthing positions (upright and recumbent) during the second stage of labour, on important maternal and fetal outcomes for women with epidural analgesia...

A human bone marrow-derived mesenchymal stromal cell (MSCs) and cord blood-derived CD34+ stem cell co-culture system was set up in order to evaluate the proliferative and differentiative effects induced by MSCs on CD34+ stem cells, and the reciprocal influences on gene expression profiles. After 10 days of co-culture, non-adherent (SN-fraction) and adherent (AD-fraction) CD34+ stem cells were collected and analysed separately. In the presence of MSCs, a significant increase in CD34+ cell number was observed (fold increase = 14...

Damage to endothelial cells contributes to acute kidney injury (AKI) by leading to impaired perfusion. Endothelial colony-forming cells (ECFCs) are endothelial precursor cells with high proliferative capacity, pro-angiogenic activity, and in vivo vessel forming potential. We hypothesized that ECFCs may ameliorate the degree of AKI and/or promote repair of the renal vasculature following ischemia/reperfusion (I/R). Rat pulmonary microvascular ECs (PMVEC) with high proliferative potential were compared with pulmonary artery ECs (PAEC) with low proliferative potential in rats subjected to renal I/R...

A spinal cord injury (SCI) interferes with the autonomic nervous system (ANS). The effect on the cardiovascular system will depend on the extent of damage to the spinal/central component of ANS. The cardiac changes are caused by loss of supraspinal sympathetic control and relatively increased parasympathetic cardiac control. Decreases in sympathetic activity result in heart rate and the arterial blood pressure changes, and may cause arrhythmias, in particular bradycardia, with the risk of cardiac arrest in those with cervical or high thoracic injuries...

Ageing associates with significant alterations in somatic/adult stem cells and therapies to counteract these might have profound benefits for health. In the blood, haematopoietic stem cell (HSC) ageing is linked to several functional shortcomings. However, besides the recent realization that individual HSCs might be preset differentially already from young age, HSCs might also age asynchronously. Evaluating the prospects for HSC rejuvenation therefore ultimately requires approaching those HSCs that are functionally affected by age...

Therapeutic monoclonal antibodies against the epidermal growth factor receptor (EGFR) act by inhibiting EGFR downstream signaling and by eliciting a natural killer (NK) cell-mediated antitumor response. The IgG1 mAb cetuximab has been used for treatment of RAS(wt) metastatic colorectal cancer (mCRC) patients, showing limited efficacy. In the present study, we address the potential of adoptive NK cell therapy to overcome these limitations investigating two allogeneic NK cell products, i.e., allogeneic activated peripheral blood NK cells (A-PBNK) and umbilical cord blood stem cell-derived NK cells (UCB-NK)...

Hematopoietic stem cell transplantation (HSCT) is the standard of care in children with Hurler syndrome (HS) as it is the only therapy that can arrest disease progression. We examined the incidence, patterns and outcomes of graft failure in all HS children undergoing first HSCT at the Royal Manchester Children's Hospital or the University of Minnesota Children's Hospital from 1983 to 2016. Implementation of busulfan pharmacokinetic monitoring started in 2004 in both institutions. Two hundred and forty HS children were included in this analysis (historical era (pre-2004), n=131; current era (post 2004), n=109)...

Microvesicles are released by different cell types and shuttle mRNAs and microRNAs which have the possibility to transfer genetic information to a target cell and alter its function. Acute myeloid leukemia is a malignant disorder, and leukemic cells occupy all the bone marrow microenvironment. In this study, we investigate the effect of leukemia microvesicles on healthy umbilical cord blood hematopoietic stem cells to find evidence of cell information transferring. Leukemia microvesicles were isolated from acute myeloid leukemia patients and were co-incubated with healthy hematopoietic stem cells...

Mesenchymal stem cells (MSCs) from human umbilical cord (UC) and cord blood (CB) share many common properties and exhibit promising clinical potential. Cellular senescence, which induces the loss of stem cells characters and disrupts their therapeutic functions, has been demonstrated to be under the regulation of microRNAs (miRNAs). In this study, we compared the miRNA profiles in early and late passage UCMSCs and CBMSCs based on deep sequencing. 224 and 170 miRNAs were significantly altered in UCMSCs and CBMSCs respectively...

Allogeneic haematopoietic cell transplantation continues to be an important curative therapy for acute lymphoblastic leukaemia (ALL). Traditionally accepted indications for allografting adult ALL patients need reevaluation in light of outcomes with paediatric-like intensive regimens. Minimal residual disease status and oncogenetics can be used for restratification of standard risk patients. A greater body of data on haematopoietic cell transplantation (HCT) outcomes from haploidentical and cord blood donor sources has been generated in recent years...

In umbilical cord blood (UCB) transplantation, UCB units are typically thawed, washed and infused into the patient as rapidly as possible. In some instances, there is a delay in the time from the unit thaw/wash procedure to infusion into the patient. Therefore, we examined the effect of thaw duration time on engraftment outcomes in 567 patients undergoing UCB transplantation. With a range of 32 to 523 minutes, a prolonged thaw duration had no obvious effect on the incidence of neutrophil engraftment or time to recovery...

INTRODUCTION: Colorectal cancer (CRC) is the second leading cause of cancer mortality in the U.S.; however, if the population aged 50 years or older received routine screening, approximately 60% of these deaths could be eliminated. This study investigates whether adults, aged 50-75 years, with one of three disabilities (blind/low vision [BLV], intellectual disability [ID], spinal cord injury [SCI]) receive CRC screening at rates equivalent to adults without the three disabilities, by accounting for combinations of recommended CRC screenings during a 10-year period (colonoscopy, sigmoidoscopy, fecal occult blood test)...
