Chorioamnionitis and intrauterine growth retardation (IUGR) are risk factors for cerebral palsy (CP). Common bacteria isolated in chorioamnionitis include group B Streptococcus (GBS) serotypes Ia and III. Little is known about the impact of placental inflammation induced by different bacteria, including different GBS strains. We aimed to test the impact of chorioamnionitis induced by two common GBS serotypes (GBSIa and GBSIII) on growth and neuromotor outcomes in the progeny. Dams were exposed at the end of gestation to either saline, inactivated GBSIa or GBSIII...

INTRODUCTION: Surgical closure of late-stage pressure ulcers (PUs) poses challenges in the immobilized population due to the high rate of complications, including infection, dehiscence, and recurrence. Muscle flap closure is the standard treatment for chronic, late-stage (stage 4) PUs, characterized by the European Pressure Ulcer Advisory Panel and National Pressure Ulcer Advisory Panel as full-thickness tissue loss with exposure of bone, tendon, or muscle. OBJECTIVE: The aim of this study is to evaluate the outcomes associated with the use of a cryopreserved placental membrane containing viable cells (vCPM) graft for the augmentation of surgical flap closure in nonhealing perineal ulcers...

The mammalian penis is a complex hydraulic organ of cavernous (spongy) tissue supported by both smooth and skeletal muscle structures. In placental mammals, the paired ‎Musculus ischiocavernosi anchor the corpora cavernosa to the pelvis (at the ischium), and the paired M. bulbospongiosi converge as they envelop the base of the corpus spongiosum. Male marsupials have a dramatically different anatomy, however, in which both sets of paired muscles remain separate, have a bulbous, globular shape and do not have any direct connection to the pelvis...

Purpose: To clarify the distinct molecular pathogenesis of central serous chorioretinopathy (CSC) and pachychoroid neovasculopathy (PNV). Methods: Aqueous humor (AH) was collected from 18 acute CSC, 20 chronic CSC, and 20 PNV patients. Concentrations of 30 cytokines in the AH were analyzed using a multiplex bead immunoassay, and the cytokine profiles were compared among these three groups of patients. The areas of choroidal vascular hyperpermeability (CVH) and choroidal thickness (CT), including measurement of the vascular layers, were investigated to analyze the features of choroidal abnormality in acute CSC, chronic CSC, and PNV...

Background: Intravitreal ranibizumab injection (IRI) is effective for patients with exudative age-related macular degeneration (AMD) and decreases intraocular levels of vascular endothelial growth factor (VEGF), but VEGF receptor intraocular dynamics after IRI are unclear. Therefore, we evaluated changes in the aqueous humor levels of soluble vascular endothelial growth factor receptor (sVEGFR)-1, sVEGFR-2, and their ligands for these receptors (VEGF) patients with AMD receiving IRI. Methods: The subjects were 24 patients with AMD (24 eyes) who received 3 doses of IRI at monthly intervals...

The diabetic syndrome affects pregnancy, contributing to placental functional and structural disruptions and impaired fetal development, with many reports indicating tobacco-associated morbidity and perinatal mortality. In our study, an experimental rat model of diabetes and cigarette smoke exposure in pregnant rats was used to determine the impact of the combination of diabetes and exposure to cigarette smoke during pregnancy on maternal oxidative stress biomarkers and placental and fetal development. Diabetes was induced by streptozotocin, and dams were exposed to cigarette smoke by mainstream smoke generated by a mechanical smoking device and delivered into a chamber...

BACKGROUND: Plasmodium falciparum infected erythrocytes sequestering in placental tissue release Plasmodium lactate dehydrogenase (pLDH) and histidine-rich protein-II (HRP-II). These proteins can be detected in peripheral blood using monoclonal antibody-based rapid diagnostic tests (RDTs). Nevertheless, studies to evaluate the reliability of RDTs in detecting placental malaria compared with microscopy of placental tissue impression smear (PTIS) as the gold standard are scarce. METHODS: Between August 2013 and January 2015, Giemsa-stained blood smears for peripheral blood smear (Pbs), placental intervillous space (IVS) blood smear and placental tissue impression smear (PTIS)] were prepared from HIV-negative women during delivery at the Marie Reine Medical Health Centre in Yaoundé, Cameroon...

In recent years, the incidence of placenta accreta and associated complications has increased significantly. The authors report the case of a pregnant woman in the 5th month of pregnancy for premature rupture of the membranes. The placenta was inserted low. The evolution was marked spontaneous work followed by the expulsion of the fetus. The delivery of the placenta was haemorrhagic and incomplete. Ultrasonic testing showed a placental fragment integrated in the thickness of the myometrium. Conservative treatment with methotrexate was published a few days later and MRI showed that the anterior uterine sac was filled with blood clots associated with pelvic effusion...

OBJECTIVE: To determine the magnetic resonance imaging (MRI)-detectable morphology of the placental cotyledon, we proposed the first cotyledon appearance scores on MRI. Cotyledon appearance scores consist of two subscores: orthogonal and parallel cotyledon appearance scores. These represent cotyledon appearance orthogonal or parallel to the placental thickness, respectively. STUDY DESIGN: This retrospective study was approved by the institutional review board of our hospital...

Low birthweight is associated with both perinatal and long-term morbidity and mortality and may be a result of abnormal placental development and function. Studies in singletons have reported associations between features of placental morphology and birthweight. Evaluating similar associations within twin pairs offers a unique opportunity to control for key confounders shared within a twin pair, including gestational age, parental characteristics, and intrauterine environment, which may otherwise be unfeasible...

BACKGROUND: Worldwide, placenta-related complications contribute to adverse pregnancy outcomes, such as pre-eclampsia, fetal growth restriction and preterm birth, with implications for the future health of mothers and offspring. The placenta develops in the periconception period and forms the interface between mother and embryo/fetus. An unhealthy periconceptional maternal lifestyle, such as smoking, alcohol and under- and over-nutrition, can detrimentally influence placental development and function...

INTRODUCTION: Healing of tendon injuries is often plagued by significant scar formation and compromised biomechanical function. For those with diabetes, these injuries are further complicated by alterations to the extracellular matrix of the tendon, poor circulation, and delayed wound healing; consequently, complications and re-rupture rates for patients with diabetes are reported higher than the typical patient population. Placental derived membranes, specifically dehydrated human amnion/chorion membranes (dACMs), have been utilized clinically as an adhesion barrier, and these membranes have been shown to reduce scarring and aid in tissue repair...
