Pregnancy entails a U-shaped trajectory in human brain structure linked to hormones and maternal attachment.

Growing evidence places the gestational period as a unique moment of heightened neuroplasticity in adult life. In this longitudinal study spanning pre, during, and post pregnancy, we unveil a U-shaped trajectory in gray matter (GM) volume, which dips in late pregnancy and partially recovers during postpartum. These changes are most prominent in brain regions associated with the Default Mode and Frontoparietal Network.

Immunotherapy for advanced-stage squamous cell lung cancer: the state of the art and outstanding questions.

Immune-checkpoint inhibitors (ICIs) have transformed the treatment paradigm for advanced-stage squamous non-small-cell lung cancer (LUSC), a histological subtype associated with inferior outcomes compared with lung adenocarcinoma. However, only a subset of patients derive durable clinical benefit. In the first-line setting, multiple ICI regimens are available, including anti-PD-(L)1 antibodies as monotherapy, in combination with chemotherapy, or with an anti-CTLA4 antibody with or without chemotherapy.

International multicenter validation of AI-driven ultrasound detection of ovarian cancer.

Ovarian lesions are common and often incidentally detected. A critical shortage of expert ultrasound examiners has raised concerns of unnecessary interventions and delayed cancer diagnoses. Deep learning has shown promising results in the detection of ovarian cancer in ultrasound images; however, external validation is lacking.

Systematic review and meta-analysis on the association of metabolic syndrome in women with overactive bladder.

Aims: A systematic review and meta-analysis were performed to determine the association of metabolic syndrome (METS) in women with and without overactive bladder (OAB).

Methods: PRISMA guidelines were followed and the protocol was registered at PROSPERO (CRD42024606398). We searched PubMed, Embase, Cochrane Library, and LILACS databases to obtain relevant articles for studies reporting METS outcomes related to OAB published through October 2024.

Morphological Description of the Embryonic to Fetal Development of the Menisco- Tibio-Popliteus-Fibular Complex and the Anterolateral Ligament.

Background: Little information is available on the embryology of the structures that connect the lateral meniscus to its nearby structures (proximal tibia, fibular head, and popliteus tendon), which restrict lateral meniscal extrusion.

Purpose: To describe the menisco-tibio-popliteus-fibular complex (MTPFC)-conformed by the lateral meniscotibial ligament (LMTL), popliteofibular ligament, meniscofibular ligament, and the 2 popliteomeniscal ligaments (superior and inferior)-and anterolateral ligament (ALL) of the knee in human embryos/fetuses from weeks 9 to 37 of gestation.

Study Design: Descriptive laboratory study.

Aberrant right subclavian artery: the importance of distinguishing between isolated and non-isolated cases in prenatal diagnosis and clinical management.

Objectives: This study aimed to evaluate the association of aberrant right subclavian artery (ARSA) with genetic abnormalities and postnatal symptomatology, by comparing isolated and non-isolated ARSA cases.

Methods: Retrospective, descriptive and comparative study involving fetuses diagnosed with ARSA during routine fetal ultrasound scans, between 19 and 40 weeks, in a tertiary referral university hospital in Barcelona from January 2007 to December 2023.

Results: Out of 154 fetuses diagnosed with ARSA, 75.

Prevalence of contrast intravasation in HyCoSy/HyFoSy. Results of a multicenter study and systematic review of the literature with meta-analysis.

Objective: To determine the frequency of uterine contrast agent intravasation during HyCoSy/HyFoSy for assessing tubal patency in infertile women.

Methods: Prospective observational multicenter study performed in nine European university hospitals, comprising a series of non-consecutive women who underwent HyFoSy (ExEm foam) for tubal patency assessment in the context of infertility between May 2016 and December 2022. All examinations were performed using the same scanning protocol.

Particulate air pollution at the time of oocyte retrieval is independently associated with reduced odds of live birth in subsequent frozen embryo transfers.

Study Question: Does exposure to particulate matter (PM) air pollution prior to oocyte retrieval or subsequent frozen embryo transfer (FET) affect the odds of live birth?

Summary Answer: Live birth rates are lower when particulate matter (PM2.5 and PM10) levels are higher prior to oocyte retrieval, regardless of the conditions at the time of embryo transfer.

What Is Known Already: Exposure to air pollution is associated with adverse reproductive outcomes, including reduced fecundity and ovarian reserve, and an increased risk of infertility and pregnancy loss.

Prognostic Significance of PD-L1 Expression on Circulating Myeloid-Derived Suppressor Cells in NSCLC Patients Treated with Anti-PD-1/PD-L1 Checkpoint Inhibitors.

Even though anti-PD-1/PD-L1 immune checkpoint inhibitors (ICIs) in non-small cell lung cancer (NSCLC) have improved survival, a high percentage of patients still do not respond to ICIs. Myeloid-derived suppressor cells (MDSCs) are circulating cells that express PD-L1 and can infiltrate and proliferate in the tumor microenvironment, inducing immunosuppression. By evaluating changes in PD-L1 expression of live peripheral blood MDSCs, we are able to define a new PD-L1 index, useful in predicting ICI escape in NSCLC patients before initiating anti-PD-1/PD-L1 immunotherapy.

NOTCH and PTP4A3 alterations emerge as novel predictive biomarkers and potential therapeutic targets in pleural mesothelioma.

Background: Previous studies showed opposite effects of NOTCH1 and NOTCH2 on mesothelioma cell survival under hypoxia. Mechanisms underlying these effects are not still clear and this pathway plays a key role in angiogenesis and cancer stem cells (CSCs) self-renewal processes.

Purpose: In this study we evaluated whether NOTCH1, NOTCH2 copy number alterations (CNAs) might predict prognosis of patients with pleural mesothelioma (PM) and if the modulation of this pathway might target CSCs, potentiating pemetrexed activity, also in hypoxic conditions.

First-trimester uterine artery pulsatility index and preeclampsia risk in pregnancies after artificial frozen embryo transfer: analysis of over 27,000 pregnancies.

Background: Accumulating evidence indicates that pregnancies after artificial cycle frozen embryo transfer are associated with an increased risk of preeclampsia. Uterine artery Doppler, along with maternal factors and serum biomarkers, is a crucial biomarker for first-trimester preeclampsia screening, aiding in identifying "high-risk" patients. Guidelines strongly recommend administering aspirin (150 mg/d) in these women, owing to robust evidence demonstrating a 62% reduction in the incidence of preeclampsia.

Long-term follow-up after laparoscopic reparation of pelvic organ prolapses in a large teaching gynecological center.

Objective: To provide a description of laparoscopic approach to correct pelvic organ prolapses and evaluate the risk factors associated with the prolapse recurrence.

Study Design: We retrospectively analyzed 418 patients with symptomatic pelvic organ prolapse who underwent a laparoscopic reparation at our university center from 2010 to 2020. Prolapses were assessed by Baden-Walker system (stage I-IV).

Age and phytoestrogen use, but not resilience, influence urinary incontinence in postmenopausal women.

Background: The aim of this study was to determine factors involved in urinary incontinence (UI), and psychological resilience in postmenopausal women.

Methods: In this cross-sectional study, 137 postmenopausal women (aged 50-75 years) filled out the 4-item International Consultation on Incontinence Questionnaire short form (ICIQ-SF), the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10), the 10-item Connor-Davidson Resilience Scale (CD-RISC), and a questionnaire containing personal data. We designed a directed acyclic graph (DAG) to identify covariates related to urinary incontinence and resilience in postmenopausal women.

Efficacy in patients with -positive non-small-cell lung cancer treated with dacomitinib who had skin adverse events: analyses from ARCHER 1050.

We investigated association between skin adverse events (AEs) and efficacy with dacomitinib in patients with -positive non-small-cell lung cancer (NSCLC). analyses from ARCHER 1050 evaluated efficacy in patients who did and did not experience grade ≥2 skin AEs with dacomitinib. Landmark analyses were performed at 3 and 6 months.
