Combined pyrotinib and fulvestrant for hormone receptor-positive and HER2-positive metastatic breast cancer: A multicenter, single-arm, phase II trial.

This multicenter, single-arm, phase II clinical trial (NCT04034589) evaluated the efficacy and safety of pyrotinib combined with fulvestrant in patients with HR-positive/HER2-positive metastatic breast cancer who had experienced trastuzumab treatment failure. A total of 46 patients were enrolled, receiving pyrotinib orally once daily and fulvestrant intramuscularly on days 1 and 15 of cycle 1, followed by monthly doses on day 1. The primary endpoint was progression-free survival (PFS), while secondary endpoints included overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety.

GLS1-mediated glutamine metabolism mitigates oxidative stress-induced matrix degradation, ferroptosis, and senescence in nucleus pulposus cells by modulating Fe homeostasis.

Intervertebral disc degeneration (IDD) is intricately linked to the pathogenesis of low back pain (LBP). The balance of nucleus pulposus (NP) cell and intervertebral disc (IVD) integrity is significantly supported by amino acid metabolism within an avascular milieu. However, the specific metabolic demands during the progression of IDD are not fully understood.

The objective of this study was to offer a comprehensive assessment of the risk factors for pregnancy loss in patients with a history of RPL following therapeutic interventions.

Peri-implantation treatment with TNF-α inhibitor for endometriosis and/or adenomyosis women undergoing frozen-thawed embryo transfer: A retrospective cohort study.

Problem: Endometriosis and adenomyosis have common pathogenesis and close relationship, with multi-factors involved in related infertility and IVF failure. They lead to anatomical changes, ovarian reserve reduction, endocrine abnormalities, altered endometrial receptivity and immunological dysfunction. Collective evidence indicate that abnormal function of immune cells and secretion of cytokines are closely related to reproductive outcomes among the women.

Diagnosis of liver hemangioma using magnetic resonance diffusion-derived vessel density (DDVD) pixelwise map: a preliminary descriptive study.

Background: Liver hemangiomas (HGs) are characterized by cavernous venous spaces delineated by a lining of vascular endothelial cells and interspersed with connective tissue septa. Typically, a liver HG has higher apparent diffusion coefficient (ADC) and T2 values than those of hepatocellular carcinomas (HCCs) and liver metastases, and lower ADC and T2 values than those of liver simple cysts. However, a portion of HGs shows ADC and T2 overlapping with those of HCC, liver metastasis, and simple cyst.

Association of serum Klotho with the severity and mortality among adults with cardiovascular-kidney-metabolic syndrome.

Background: Cardiovascular-kidney-metabolic (CKM) syndrome is characterized as a systemic disease resulting from the pathophysiological interplay among metabolic risk factors, chronic kidney disease (CKD), and cardiovascular disease (CVD). The Klotho protein may serve as a novel biomarker. However, the utility of serum Klotho levels as an indicator of severity and mortality risk in CKM syndrome remains uncertain.

Controlled low central venous pressure maintenance level during laparoscopic hepatectomy negatively associated with PHLF incidence: a retrospective propensity score matching study.

Background: Posthepatectomy liver failure (PHLF), the most serious complication after hepatectomy, may evoke multisystemic complications and even mortality. Despite numerous studies demonstrated the safety and efficacy of controlled low central venous pressure (CLCVP), the optimal central venous pressure (CVP) maintenance level during CLCVP and its relationship with PHLF remain controversial. Therefore, the present study aimed to evaluate the association between the lowest CVP maintenance level during CLCVP and PHLF.
