Testing calpain inhibition in tumor endothelial cells: novel targetable biomarkers against glioblastoma malignancy.

Introduction: Glioblastoma -wildtype (GBM) is the most malignant brain tumor in adults, with a poor prognosis of approximately 15 months after diagnosis. Most patients suffer from a recurrence in <1 year, and this renders GBM a life-threatening challenge. Among molecular mechanisms driving GBM aggressiveness, angiogenesis mediated by GBM endothelial cells (GECs) deserves consideration as a therapeutic turning point.

Global health systems strengthening: FIGO's strategic view on reducing maternal and newborn mortality worldwide.

Objective: To demonstrate that successful health systems strengthening (HSS) projects have addressed disparities and inequities in maternal and perinatal care in low-income countries.

Methods: A comprehensive literature review covered the period between 1980 and 2022, focusing on successful HSS interventions within health systems' seven core components that improved maternal and perinatal care.

Results: The findings highlight the importance of integrating quality interventions into robust health systems, as this has been shown to reduce maternal and newborn mortality.

Role of Luteolin as Potential New Therapeutic Option for Patients with Glioblastoma through Regulation of Sphingolipid Rheostat.

Glioblastoma (GBM) is the most aggressive brain tumor, still considered incurable. In this study, conducted on primary GBM stem cells (GSCs), specifically selected as the most therapy-resistant, we examined the efficacy of luteolin, a natural flavonoid, as an anti-tumoral compound. Luteolin is known to impact the sphingolipid rheostat, a pathway regulated by the proliferative sphingosine-1-phosphate (S1P) and the proapoptotic ceramide (Cer), and implicated in numerous oncopromoter biological processes.

Basal serum level of Δ4-androstenedione reflects the ovaries' ability to respond to stimulation in IVF cycles: setting up a new reliable index of both ovarian reserve and response.

Purpose: Adequate androgen levels are necessary for regular follicular growth, progression beyond the pre-antral stage, and prevention of follicular atresia. The main purpose of this study was to investigate whether baseline androgen levels had a predictive value on stimulation outcomes in IVF cycles. The secondary purpose was to compare the possible predictive value of androgens with that of already known markers.

Stage IV endometriosis: to treat or not to treat before in-vitro fertilization? Further considerations besides the pregnancy rate: a case of near-miss for spontaneous hemoperitoneum.

Endometriosis represents a well-known cause of infertility. Recently, its association with spontaneous hemoperitoneum in pregnancy (SHIP) was reported. Its occurrence seems to be increased in patients with endometriosis who underwent IVF techniques.

Effects of Metformin as Add-On Therapy against Glioblastoma: An Old Medicine for Novel Oncology Therapeutics.

Background: Glioblastoma is the most aggressive primary brain malignancy in adults, with a poor prognosis of about 14 months. Recent evidence ascribed to metformin (MET), an antihyperglycemic drug, the potential to reduce cancer incidence and progression, but the molecular mechanisms underlying these effects need to be better investigated.

Methods: Here, we tested the efficacy of MET on = 10 primary glioblastoma endothelial cells (GECs), by viability and proliferation tests, as MTT and Live/Dead assays, apoptosis tests, as annexin V assay and caspase 3/7 activity, functional tests as tube-like structure formation and migration assay and by mRNA and protein expression performed by quantitative real-time PCR analysis (qRT-PCR) and Western Blot, respectively.

Frontiers in Anti-Cancer Drug Discovery: Challenges and Perspectives of Metformin as Anti-Angiogenic Add-On Therapy in Glioblastoma.

Glioblastoma is the most common primitive tumor in adult central nervous system (CNS), classified as grade IV according to WHO 2016 classification. Glioblastoma shows a poor prognosis with an average survival of approximately 15 months, representing an extreme therapeutic challenge. One of its distinctive and aggressive features is aberrant angiogenesis, which drives tumor neovascularization, representing a promising candidate for molecular target therapy.

Minimal prevalence of HPV vaccination and common occurrence of high-risk HPV types in pregnant women with HIV: data from a national study in Italy.

Among 733 pregnant women with HIV followed between 2013 and 2021, only 8 (1.1%) had prior HPV vaccination. One had low-grade squamous intraepithelial lesions [LSIL], and none had HPV type information.

Hyperandrogenism and menstrual imbalance are the best predictors of metformin response in PCOS patients.

Background: Moving from the correlation between insulin-resistance and PCOS, metformin has been administered in some PCOS women improving ovulatory and metabolic functions and decreasing androgen levels. Inconsistency and unpredictability of response to metformin limit its extensive use. Aim of this study was to identify reliable predictors of response to metformin therapy for weight loss and reduction in plasma androgen levels using ANNs (artificial neural networks).

Stem Cells in Clinical Trials for Pelvic Floor Disorders: a Systematic Literature Review.

Pelvic floor disorders (PFDs) include a series of conditions that can be poorly tolerated, negatively affecting the quality of life. Current treatment options show unsatisfactory results and new ones are therefore needed. Stem cell (SC) therapy might be an alternative treatment strategy.

Meconium-stained amniotic fluid and histologic signs of fetal distress in stillbirths.

Objective: Stillbirth is one of the most devastating adverse pregnancy outcome, but it is often associated with a missing post-mortem histological examination. We aimed at evaluating whether the staining of amniotic fluid reflects the fetal conditions surrounding the death and if it correlates with any histologic sign of fetal distress.

Study Design: Terminal gasping (represented by the massive presence of intra-alveolar squamous cells), thymic and adrenal cortex modifications were evaluated as histologic signs of fetal distress in stillbirths, and stratified according to the degree of staining of the amniotic fluid.

Chronic deciduitis in stillbirths: are there any specific clinical associations?

Introduction: Placental chronic deciduitis is a lesion consistent with the presence of plasma cells within the placental basal plate. It could be associated with adverse pregnancy outcomes, including stillbirth.

Methods: We retrospectively evaluated a cohort of 180 antepartum stillborn cases from singleton pregnancies, with the aim of investigating the clinical-histopathological relationship.

A closer look at discordant placental echogenicity: two cases under the microscope.

Discordant placental echogenicity is observed in MC pregnancies complicated with twin anemia-polycythemia sequence, but could also belong to complicated singleton gestation.

An international genome-wide meta-analysis of primary biliary cholangitis: Novel risk loci and candidate drugs.

Backgrounds & Aims: Primary biliary cholangitis (PBC) is a chronic liver disease in which autoimmune destruction of the small intrahepatic bile ducts eventually leads to cirrhosis. Many patients have inadequate response to licensed medications, motivating the search for novel therapies. Previous genome-wide association studies (GWAS) and meta-analyses (GWMA) of PBC have identified numerous risk loci for this condition, providing insight into its aetiology.

Results: Among 934 women, 536 (57.

X Chromosome Contribution to the Genetic Architecture of Primary Biliary Cholangitis.

Background & Aims: Genome-wide association studies in primary biliary cholangitis (PBC) have failed to find X chromosome (chrX) variants associated with the disease. Here, we specifically explore the chrX contribution to PBC, a sexually dimorphic complex autoimmune disease.

Methods: We performed a chrX-wide association study, including genotype data from 5 genome-wide association studies (from Italy, United Kingdom, Canada, China, and Japan; 5244 case patients and 11,875 control individuals).

Dynamic expression of NR2F1 and SOX2 in developing and adult human cortex: comparison with cortical malformations.

The neocortex, the most recently evolved brain region in mammals, is characterized by its unique areal and laminar organization. Distinct cortical layers and areas can be identified by the presence of graded expression of transcription factors and molecular determinants defining neuronal identity. However, little is known about the expression of key master genes orchestrating human cortical development.

Comparison of treatments for the prevention of fetal growth restriction in obstetric antiphospholipid syndrome: a systematic review and network meta-analysis.

Women with criteria and non-criteria obstetric antiphospholipid syndrome (APS) carry an increased risk of pregnancy complications, including fetal growth restriction (FGR). The management of obstetric APS traditionally involves clinicians, obstetricians and gynaecologists; however, the most appropriate prophylactic treatment strategy for FGR prevention in APS is still debated. We performed a systematic review and network meta-analysis (NetMA) to summarize current evidence on pharmacological treatments for the prevention of FGR in APS.
