The WHO atlas for female-genital schistosomiasis: Co-design of a practicable diagnostic guide, digital support and training.

Up to 56 million young and adult women of African origin suffer from Female Genital Schistosomiasis (FGS). The transmission of schistosomiasis happens through contact with schistosomiasis infested fresh water in rivers and lakes. The transmission vector is the snail that releases immature worms capable of penetrating the human skin.

Placental weight, surface area, shape and thickness - Relations with maternal ethnicity and cardio-metabolic factors during pregnancy.

Introduction: A better understanding of the determinants of placental growth is needed. Our primary aim was to explore associations between maternal ethnic origin and cardio-metabolic factors during pregnancy, and placental weight, surface area, shape and thickness.

Methods: A multi-ethnic population-based cohort study of 474 pregnant women examined at mean 15 and 28 weeks' gestation.

Gene expression of fibrinolytic markers in coronary thrombi.

Background: The fibrinolytic system plays an important role in coronary artery atherothrombosis, and especially circulating plasminogen-activator inhibitor (PAI) type 1 (PAI-1) associates with increased mortality, infarct size and heart failure in patients with myocardial infarction (MI). In a cross-sectional study, we aimed to study whether genes encoding tissue plasminogen activator (tPA), urinary-type plasminogen activator (uPA), PAI-1 and PAI-2 are expressed in coronary thrombi from acute ST-elevation MI (STEMI) patients. Any relations to myocardial injury measured by peak troponin T, time from symptom onset to Percutaneous Coronary Intervention (PCI), and to different cell types present in the thrombi were also explored.

TIMP-1 expression in coronary thrombi associate with myocardial injury in ST-elevation myocardial infarction patients.

Background: Matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) are considered important both in atherosclerosis and remodeling after acute myocardial infarction (AMI). We aimed to study genetic expression and presence of MMP-2, MMP-9, TIMP-1, TIMP-2 and the extracellular MMP-inducer (EMMPRIN) in coronary thrombi. Circulating levels and genetic expression in circulating leukocytes were also assessed, and relations to degree of myocardial injury measured by troponin T and time from symptom to PCI were explored.

Platelet alloimmunization is associated with low grade chronic histiocytic intervillositis - A new link to a rare placental lesion?

Introduction: Maternal alloimmunization against human platelet antigen (HPA)-1a has been implied to mediate both reduced birth weight and chronic placental inflammation. Fetal growth restriction is associated with different types of chronic inflammation in the placenta, mainly chronic histiocytic intervillositis and chronic villitis. The aim of this prospective study was to do a systematic examination of placentas from HPA-1a alloimmunized pregnancies, with focus on the histopathological and immunohistochemical diagnosis of variants of chronic inflammation.

The Inflammasome Signaling Pathway Is Actively Regulated and Related to Myocardial Damage in Coronary Thrombi from Patients with STEMI.

Background: The Nod-Like-Receptor-Protein-3 (NLRP3) inflammasome and the Interleukin-6 (IL-6) pathways are central mechanisms of the inflammatory response in myocardial reperfusion injury. Expanding our knowledge about the inflammasome signaling axis is important to improve treatment options. In a cross-sectional study, we aimed to study presence, localization, and genetic expression of inflammasome- and IL-6- signaling-related proteins in coronary thrombi and circulating leukocytes from ST-elevation myocardial infarction (STEMI) patients, with relation to myocardial injury and time from symptoms to PCI.

A systematic review of handheld tools in lieu of colposcopy for cervical neoplasia and female genital schistosomiasis.

Background: Visualization of the lesions in the lower genital tract is the mainstay for diagnosis of the four lesions found in female genital schistosomiasis (FGS), but colposcopes are generally not available in low-resource settings.

Objective: We sought to review handheld devices that could potentially be used for FGS diagnosis.

Search Strategy: We searched Medline and Embase 2015-2019 for handheld devices used in cervical cancer screening and FGS diagnosis.

Optisol-GS Storage of Cultured Human Limbal Epithelial Cells at Ambient Temperature Is Superior to Hypothermic Storage.

Purpose: To investigate the feasibility of using Optisol-GS as a convenient, xenogeneic-free alternative for storage of cultured human limbal epithelial cells (HLECS) for use in treatment of limbal stem cell deficiency (LSCD). In the present study, we compared storage of cultured HLEC using the conventional hypothermic Optisol-GS storage method at 4°C versus storage at 23°C (room temperature).

Materials And Methods: HLECs were cultured for three weeks on amniotic membrane (AM), transferred to polypropylene containers and stored in Optisol-GS for 4 days at 23°C and 4°C.

Nephrotic syndrome and pulmonary hypertension as complications of intravenous drug abuse.

This case report discusses a patient with nephrotic syndrome, pulmonary hypertension, and repeated episodes of infections. He had a history of intravenous drug abuse. Kidney biopsy revealed the rare finding of numerous foam cells, mainly in glomeruli.

Uteroplacental acute atherosis in preeclamptic pregnancies: Rates and clinical outcomes differ by tissue collection methods.

Objectives: Acute atherosis (AA) is a uteroplacental spiral artery lesion, identified by intramural lipid-laden foam cells, with highest rates in preeclampsia (PE). We compared AA detection rates in preeclampsia (PE) across three different decidual spiral artery collection methods in same patients. We tested whether the rate and topographical distribution of AA associates with clinical parameters.

Acute atherosis of decidua basalis; characterization of spiral arteries, endothelial status and activation.

Introduction: Acute atherosis (AA) is a lesion affecting uteroplacental spiral arteries during pregnancy, most frequently in preeclampsia but occasionally in normal pregnancy. It is commonly observed in untransformed spiral arteries (intact smooth muscle cell layer, lacking intramural trophoblasts). The mechanism causing lesion development is unknown.

Lymphocyte characterization of decidua basalis spiral arteries with acute atherosis in preeclamptic and normotensive pregnancies.

Uteroplacental acute atherosis (AA) is a common spiral arterial lesion in preeclampsia, characterized by intramural foam cells, fibrinoid necrosis, and a perivascular immune cell infiltrate. A clear definition of this infiltrate is lacking. Therefore, our aim was to characterize lymphocytes in pre-defined zones regarding spiral arteries with or without AA, from preeclamptic and normotensive pregnancies.

Effects of explant size on epithelial outgrowth, thickness, stratification, ultrastructure and phenotype of cultured limbal epithelial cells.

Purpose: Transplantation of limbal stem cells is a promising therapy for limbal stem cell deficiency. Limbal cells can be harvested from either a healthy part of the patient's eye or the eye of a donor. Small explants are less likely to inflict injury to the donor site.

Early development of the human placenta and pregnancy complications.

An adequately sized placenta at a suitable site with appropriate depth and centripetal progression of implantation are the major factors for optimal fetal development. The cytotrophoblasts surround the blastocyst fuses at the site of the uterine attachment. This forms a second layer of multinucleated syncytiotrophoblasts that constitutes the inner epithelial boundary of the chorionic villous against the intervillous space.

Effect of Transportation on Cultured Limbal Epithelial Sheets for Worldwide Treatment of Limbal Stem Cell Deficiency.

Limbal stem cell deficiency can be treated with transplantation of cultured human limbal epithelial cells (LEC). It can be advantageous to produce LEC in centralized labs and thereafter ship them to eye clinics. The present study used transport simulations of LEC to determine if vigorous shaking during transport altered the viability, morphology and phenotype during a 4 day-long storage of LEC with a previously described serum-free storage method.

Cultured Human Retinal Pigment Epithelial (hRPE) Sheets: A Search for Suitable Storage Conditions.

The advancement of human retinal pigment epithelial cell (hRPE) replacement therapy is partly dependent on optimization of cell culture, cell preservation, and storage medium. This study was undertaken to search for a suitable storage temperature and storage medium for hRPE. hRPE monolayer sheets were cultured under standard conditions at 37°C and then randomized for storage at six temperatures (4, 16, 20, 24, 28, and 37°C) for 7 days.

Unexplained chronic liver disease in Ethiopia: a cross-sectional study.

Background: Hepatitis B virus (HBV) infection is assumed to be the major cause of chronic liver disease (CLD) in sub-Saharan Africa. The contribution of other aetiological causes of CLD is less well documented and hence opportunities to modulate other potential risk factors are being lost. The aims of this study were to explore the aetiological spectrum of CLD in eastern Ethiopia and to identify plausible underlying risk factors for its development.

Indications for Cesarean Sections in Rural Nepal.

Objective: Globally, cesarean section (CS) rate is close to 26 %. Nepal has a reported CS rate of 5 %, with huge differences in rural (3.5 %) and urban (15 %) areas.

Cervical cytology as a diagnostic tool for female genital schistosomiasis: Correlation to cervical atypia and Schistosoma polymerase chain reaction.

Background: Female genital schistosomiasis (FGS) is a tissue reaction to lodged ova of Schistosoma haematobium in the genital mucosa. Lesions can make the mucosa friable and prone to bleeding and discharge. Women with FGS may have an increased risk of HIV acquisition, and FGS may act as a cofactor in the development of cervical cancer.

Hampered Lung Maturation in Methimazole-Induced Hypothyroidism in Fetal Chicken: Morphological and Molecular Correlates to Human Fetal Development.

Background: Molecular understanding of lung development is crucial for developing therapies and diagnostic tools. Animal models with altered thyroid hormone signaling provide mechanistic insight into thyroid-dependent neonatal lung disease. Repression of Klf2 (Krüppel-like factor 2), a suggested T3 target gene, is associated with disrupted lung development in mice.

Febrile Illness and Intravenous Antimalarial Treatment at a District Hospital in Cameroon.

Background: Malaria is one of the most common causes of mortality worldwide. The World Health Organization (WHO) has recently recommended that treatment should be guided by a laboratory diagnosis. The aim of this study is to explore patient and health care factors associated with intravenous antimalarial treatment of malaria test-negative patients at a district hospital in a malaria endemic area.

Acute atherosis in vacuum suction biopsies of decidua basalis: An evidence based research definition.

Background: Acute atherosis (AA) of the uteroplacental spiral arteries has been characterised by subendothelial lipid-laden foam cells, perivascular leukocyte infiltrates (PVI) and fibrinoid necrosis. Because precise diagnostic criteria are not available for comparative research studies we developed and tested new simplified criteria based on 237 cases.

Methods: Decidual basalis samples were collected by vacuum suction at elective cesarean deliveries.

Cracking the Egg: Potential of the Developing Chicken as a Model System for Nonclinical Safety Studies of Pharmaceuticals.

The advance of perinatal medicine has improved the survival of extremely premature babies, thereby creating a new and heterogeneous patient group with limited information on appropriate treatment regimens. The developing fetus and neonate have traditionally been ignored populations with regard to safety studies of drugs, making medication during pregnancy and in newborns a significant safety concern. Recent initiatives of the Food and Drug Administration and European Medicines Agency have been passed with the objective of expanding the safe pharmacological treatment options in these patients.

Effect of Storage Temperature on the Phenotype of Cultured Epidermal Cells Stored in Xenobiotic-Free Medium.

Purpose: Cultured epidermal cell sheets (CECS) are used in the treatment of large area burns to the body and have potential to treat limbal stem cell deficiency (LSCD) as shown in animal studies. Despite widespread use, storage options for CECS are limited. Short-term storage allows flexibility in scheduling surgery, quality control and improved transportation to clinics worldwide.
