Termination of a second-trimester pregnancy with placenta accreta spectrum disorder.

The termination of pregnancy in patients with placenta accreta spectrum disorder (PASD) during the second trimester remains uncertain. In addition, interventional radiology techniques, such as arterial embolization and balloon placement, are potential options. We evaluated the outcomes of pregnancy termination in patients with PASD during the second trimester and the effectiveness of preoperative interventional radiology techniques.

Noninvasive prenatal testing, ultrasonographic findings and poor prenatal diagnosis rates for twin pregnancies: a retrospective study.

Background: Noninvasive prenatal testing (NIPT) is increasingly used in the clinical prenatal screening of twin pregnancies, and its screening performance for chromosomal abnormalities requires further evaluation. For twin pregnancies with indications for prenatal diagnosis, there is a lack of clinical data to assess the prenatal diagnosis rate (PDR). The aim of this study was to evaluate the screening performance of NIPT for foetal chromosomal abnormalities in twin pregnancies and the PDR in the second and third trimesters.

Comparison of risk assessments for venous thromboembolism during the puerperium.

Objective: To compare the predictive value of different risk assessment methods for puerperium venous thromboembolism (VTE).

Methods: This study included 55 women with and 165 women without puerperal VTE. Using the cases, 11 assessment methods were compared.

Development of a nanozyme-based electrochemical sensor for detection of stringent response.

PpGpp (Guanosine 3',5'-bisdiphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) are important biological compounds in stringent response of organisms and play a crucial role in their growth and survival. At present, there is no report on the method for comprehensively detection of stringent response. In this study, a nanozyme-based electrochemical sensor was fabricated by self-assembly and was used for detecting stringent response with high sensitivity (Km of ppGpp is 1.

Placenta Accreta Spectrum Outcomes Using Tourniquet and Forceps for Vascular Control.

To evaluate the use of tourniquet and forceps to reduce bleeding during surgical treatment of severe placenta accreta spectrum (placenta increta and placenta percreta). A tourniquet was used in the lower part of the uterus during surgical treatment of severe placenta accreta spectrum. Severe placenta accreta spectrum was classified into two types according to the relative position of the placenta and tourniquet during surgery: upper-tourniquet type, in which the entire placenta was above the tourniquet, and lower-tourniquet type, in which part or all of the placenta was below the tourniquet.

Expression of SARS-CoV-2 entry genes ACE2 and TMPRSS2 at single cell resolution in the peripartum decidua.

Angiotensin-converting enzyme 2 (ACE2) is the key receptor for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). However, the susceptibility of the decidua to infection during the peripartum period has not been explored, even though this may affect vertical transmission. The objective of this study was to investigate the expression of ACE2 and related genes in the decidua during delivery.

Pregnancy outcomes and factors affecting the clinical effects of emergency cerclage in twin pregnancies with cervical dilation and prolapsed membranes.

Objective: To determine the effect of mid-trimester emergency cerclage in women with twin pregnancies with cervical dilation and prolapsed membranes, and to identify risk factors predicting spontaneous preterm birth (sPTB) before 28 weeks, after cerclage.

Methods: Retrospective analysis of twin gestations with cervical dilation and prolapsed membranes treated with emergency cerclage or expectant management (2015-2020). The primary outcomes were the rate of sPTB before 28 weeks and the gestational latency.

A Biallelic Frameshift Mutation in Nephronectin Causes Bilateral Renal Agenesis in Humans.

Background: Bilateral renal agenesis (BRA) is a lethal con genital anomaly caused by the failure of normal development of both kidneys early in embryonic development. Oligohydramnios on fetal ultrasonography reveals BRA. Although the exact causes are not clear, BRA is associated with mutations in many renal development genes.

Single-cell transcriptomics analysis showing functional heterogeneity in decidual stromal cells during labor.

To investigate the heterogeneity of decidual stromal cells (DSCs) and their functional alterations during delivery, we conducted single-cell RNA sequencing analysis to characterize the transcriptomic profiles of DSCs before and after labor onset. According to their transcriptomic profiles, DSCs (6382 cells) were clustered into five subgroups with different functions. Similar to stromal cells, cells in cluster 1 were involved in cell substrate adhesion.

LncRNA MALAT-1 promotes growth and metastasis of epithelial ovarian cancer via sponging microrna-22.

LncRNAs and miRNAs are emerging players in epithelial ovarian cancer (EOC). LncRNA MALAT-1 and miR-22 play vital roles in the onset and development of multiple cancers. Both of them are abnormally expressed in ovarian cancer, but the molecular basis for their involvement in EOC is unclear.

Single-cell RNA sequencing reveals heterogeneity and differential expression of decidual tissues during the peripartum period.

Objectives: The decidua is a tissue that contacts both maternal and foetal components and is pivotal to labour onset due to its location. Due to the heterogeneity of decidual tissue, it is challenging to study its role in the peripartum period. Herein, we analysed the transcriptomes of peripartum decidua at single-cell resolution.

Mahanimbine Exerts Anticancer Effects on Human Pancreatic Cancer Cells by Triggering Cell Cycle Arrest, Apoptosis, and Modulation of AKT/Mammalian Target of Rapamycin (mTOR) and Signal Transducer and Activator of Transcription 3 (STAT3) Signalling Pathways.

BACKGROUND Pancreatic cancer causes tremendous mortality across the globe mainly due to late diagnosis and unavailability of efficient chemotheruptic agents. In the current study the anticancer potential of a plant derived alkaloid, Mahanimbine, was examined against a panel of pancreatic cancer cells. MATERIAL AND METHODS The cell proliferation was determined by MTT assay.

Critical Role for Interleukin-25 in Host Protective Th2 Memory Response against Heligmosomoides polygyrus bakeri.

Infection with parasitic nematodes, especially gastrointestinal geohelminths, affects hundreds of millions of people worldwide and thus poses a major risk to global health. The host mechanism of defense against enteric nematode infection remains to be fully understood, but it involves a polarized type 2 immunity leading to alterations in intestinal function that facilitate worm expulsion. We investigated the role of interleukin-25 (IL-25) in host protection against Heligmosomoides polygyrus bakeri infection in mice.

Type 2 immunity-dependent reduction of segmented filamentous bacteria in mice infected with the helminthic parasite Nippostrongylus brasiliensis.

Background: Dynamic interactions between the host and gastrointestinal microbiota play an important role for local and systemic immune homeostasis. Helminthic parasites modulate the host immune response, resulting in protection against autoimmune disease but also increased susceptibility to pathogen infection. The underlying mechanisms remain largely unknown.
