Endometriosis is a chronic inflammatory disease characterized by the growth of endometrium-like tissues outside the uterine cavity, with an unclear pathogenesis. Analysis of single-cell sequencing data revealed the pivotal role of peritoneal macrophages in the development of endometriosis. We noted significant creatine enrichment and synthesis in peritoneal macrophages of patients with endometriosis compared to women without endometriosis.

The establishment and maintenance of pregnancy encompass a series of complex and high-energy-consuming physiological processes, resulting in a significant energy demand. Fatty acids, one of the most essential nutrients, play a crucial role in energy supply via oxidation and perform critical biological functions such as anti-inflammatory and anti-oxidant effects, which substantially impact human health. Disordered fatty acid metabolism can cause anomalies in fetal growth and development, as well as a range of pregnancy problems, which can influence the health of both the mother and the fetus.

Problem: Pregnancy complications such as spontaneous abortion, preeclampsia, and preterm birth persist, despite current interventions aimed at their prevention and treatment largely proving unsuccessful. Interleukin-27 (IL-27), composed of p28 and EBI3 subunits, binds to IL-27R, which consists of gp130 and IL-27Rα (also known as WSX-1 or TCCR), and plays a pivotal role in tumor development and inflammation regulation. At the maternal-fetal interface, IL-27 expression has been detected in trophoblasts, endometrial stromal cells, and decidual cells.

Article Synopsis
  • - The study aimed to evaluate the effectiveness of various flap techniques for repairing diabetic foot defects (DFD) and specifically assessed the anterolateral thigh perforator flap (ALTP) in treating both DFD and non-DFD wounds.
  • - Researchers analyzed data from 40 DFD patients and 43 non-DFD patients from 2010 to 2021, noting that DFD patients had more severe complications, longer healing times, and poorer recovery outcomes compared to non-DFD patients.
  • - The findings suggest that while different flap techniques can effectively repair DFD wounds, the use of free ALTP flaps carries higher postoperative risks, which can be mitigated with thorough preoperative vascular assessments. *

The significance of hypoxia at the maternal-fetal interface is proven to be self-explanatory in the context of pregnancy. During the first trimester, low oxygen conditions play a crucial role in processes such as angiogenesis, trophoblast invasion and differentiation, and immune regulation. Recently, there has been increasing research on decidual macrophages, which contribute to the maintenance of immune tolerance, placental and fetal vascular development, and spiral artery remodeling, to investigate the effects of hypoxia on their biological behaviors.

Article Synopsis
  • The endometrium transforms into a structure called decidua during pregnancy preparation, with senescent decidual stromal cells (DSCs) increasing but poorly understood mechanisms.
  • Researchers used single-cell RNA transcriptomics to discover that higher levels of the BCAA transporter SLC3A2 accompany cell senescence in DSCs during decidualization.
  • A high leucine diet contributes to increased DSC senescence and embryo loss in mice, while dNK cells can counteract this senescence through the TNFSF14/TNFRSF14 pathway, highlighting potential for therapeutic interventions in preventing pregnancy loss.

Background: The reconstruction of complex wounds of the hand still has challenges in achieving aesthetic, functional and sensory recovery. We presented our experience of using the polyfoliate and chimeric radial collateral artery perforator flaps (RCAPF) to repair complex hand defects, aiming to explore the feasibility of special-form RCAPFs in hand coverage and enhance the comprehension of their respective indications.

Methods: From June 2014 to March 2021, 26 cases (19 males and 7 females, mean 44.

Background: Uterine endometrial cancer (UEC) is a common gynecological estrogen-dependent carcinoma, usually accompanied by intermenstrual bleeding. Active heme metabolism frequently plays an increasingly important role in many diseases, especially in cancers. Tumor-associated macrophages (TAMs) are the major population in the immune microenvironment of UEC.

Premature ovarian insufficiency (POI) critically affects female reproductive health, with obesity being a significant and recognized risk factor. Interleukin-27 (IL-27), known for its role in immune modulation and inflammation, has garnered attention in metabolic syndrome research. Nonetheless, the role of these immunometabolic factors on the initiation of POI remains to be unraveled.

The presence of extensive infiltrated macrophages with impaired phagocytosis is widely recognised as a significant regulator for the development of endometriosis (EMs). Nevertheless, the metabolic characteristics and the fundamental mechanism of impaired macrophage phagocytosis are yet to be clarified. Here, we observe that there is the decreased expression of haematopoietic cellular kinase (HCK) in macrophage of peritoneal fluid from EMs patients, which might be attributed to high oestrogen and hypoxia condition.

Article Synopsis
  • Immune problems can cause spontaneous miscarriage (SM), and scientists are looking into new medicines that could help manage this issue.
  • One of these medicines is called rapamycin, which can help the body accept the embryo better and also helps recycle old cells.
  • While rapamycin shows promise for treating SM, researchers are cautioning that it could also harm the pregnancy if not used carefully, so more studies are needed to understand its effects fully.

Endometriosis (EM) is one of the diseases related to retrograded menstruation and hemoglobin. Heme, released from hemoglobin, is degraded by heme oxygenase-1 (HO-1). In EM lesions, heme metabolites regulate processes such as inflammation, redox balance, autophagy, dysmenorrhea, malignancy, and invasion, where macrophages (Mø) play a fundamental role in their interactions.

Problem: Polycystic ovary syndrome (PCOS), a prevalent endocrine-metabolic disorder, presents considerable therapeutic challenges due to its complex and elusive pathophysiology.

Method Of Study: We employed three machine learning algorithms to identify potential biomarkers within a training dataset, comprising GSE138518, GSE155489, and GSE193123. The diagnostic accuracy of these biomarkers was rigorously evaluated using a validation dataset using area under the curve (AUC) metrics.

In Brief: The mechanism underlying the accumulation of γδT cells in the decidua, which helps maintain maternal-fetal immunotolerance in early pregnancy, is unknown. This study reveals that DSC-derived RANKL upregulates ICAM-1 expression via the NF-κB pathway to enable γδT cell accumulation in the early decidua.

Abstract: Decidual γδT (dγδT) cells help maintain maternal-fetal immunotolerance in early pregnancy.

Prokineticin 1 (PROK1) is a secreted protein involved in a range of physiological activities such as cell proliferation, migration, angiogenesis, and neuronal cell proliferation. Emerging evidences show that PROK1/PROK receptors (PROKRs) are expressed by trophoblasts, and decidual stroma cells at the maternal-fetal interface. PROK1 plays a critical role in successful pregnancy establishment by regulating the decidualization, implantation and placental development.

Though firstly identified in cerebral folate deficiency, autoantibodies against folate receptors (FRAbs) have been implicated in pregnancy complications such as miscarriage; however, the underlying mechanism needs to be further elaborated. FRAbs can be produced via sensitization mediated by folate-binding protein as well as gene mutation, aberrant modulation, or degradation of folate receptors (FRs). FRAbs may interfere with folate internalization and metabolism through blocking or binding with FRs.
