OBJECTIVE: Haptoglobin (Hp) has key immunoregulatory roles that vary with phenotype (Hp1-1, Hp2-1, Hp2-2). Cord blood Hp expression is switched-off in the normal fetus. We hypothesized that in the setting of fetal inflammation placenta becomes inundated with Hp of fetal origin that in turn modulates the output of PGE2 and MMP-9 in a phenotype dependent manner. METHODS: Placentas from 40 pregnancies complicated by preterm birth (PTB) (<37 weeks), without (n = 15) or with (n = 25) intra-amniotic infection and histological chorioamnionitis (HCA) were scored for intensity of Hp immunostaining...

Human mesenchymal stem cells (MSCs) express scavenger receptors that internalize lipids, including oxidized low-density lipoprotein (oxLDL). We report that MSCs phagocytose Mycobacterium tuberculosis (Mtb) through two types of scavenger receptors (SRs; MARCO and SR-B1), as blockade of the receptors with antibodies or siRNA knockdown decreased the uptake of Mtb. MSCs also expressed mannose receptor (MR) that was found to endocytose rhodamine-labeled mannosylated BSA (rMBSA), though the receptor was not involved in the uptake of Mtb...

INTRODUCTION: Total hip arthroplasty (THA) is performed as a 2-stage or single stage procedure in patients with a history of septic arthritis of the native hip joint. The decision is based on whether the infection is active or quiescent in the joint. The aim of this study was to compare the outcomes of total hip arthroplasty for septic arthritis of the native hip to a control series of patients treated for primary osteoarthritis of the hip with standard THA. METHODS: Between March 2000 and March 2013, 18 cases of septic arthritis of the hip treated with THA were retrospectively identified...

PURPOSE: Osteogenesis imperfecta (OI) is a condition characterised by bone fragility and multiple fractures, which cause considerable morbidity in the affected patients. Most cases are associated with mutations in one of the type I collagen genes. Recently, bisphosponates have been used widely to reduce pain and the incidence of fragility fractures in OI in children, even though there have been concerns raised regarding the long-term complications of it due to their effect on the bone...

BACKGROUND: Chronic hypertension in adults causes arterial lengthening in major arteries, but the effects of early fetal hypertension on the twin-twin transfusion syndrome recipient's vascular architecture remains unknown. OBJECTIVE: We hypothesize that arterial cord redundancy is related to recipient hypertension and subsequent heart failure. Our objectives were to: (1) establish a 3-dimensional color Doppler ultrasound method of measuring umbilical arterial length relative to its corresponding venous segment in the umbilical cord using artery vein angle; (2) compare recipient artery vein angle to gestational age-matched controls; and (3) test the association of artery vein angle with recipient heart failure...

OBJECTIVES: The objective of our study was to test the hypothesis that in utero repair of surgically created spina bifida in a sheep model using cryopreserved human umbilical cord (HUC) patch improves neurological outcome. METHODS: Spina bifida with myelotomy was surgically created in timed pregnant ewes at gestational day (GD) 75. The fetuses were randomly assigned to unrepaired versus HUC and treated at GD 95 and then delivered at GD 140. Neurological evaluation was performed using the Texas Spinal Cord Injury Scale (TSCIS), bladder control using ultrasound, and the hindbrain herniation...

BACKGROUND: There is an urgent need is for a regenerative patch for in utero repair of spina bifida in situations in which primary closure is difficult. CASES: We present two cases of large myeloschisis defects that underwent in utero spina bifida repair at midgestation with closure of the skin defect by using a cryopreserved human umbilical cord patch. The pregnancies were uncomplicated, and the births occurred at 37 weeks by planned cesarean delivery. The repair sites were intact with no evidence of cerebrospinal fluid leakage, with skin regenerated after delivery over a period of 3-4 weeks...
