Introduction: Breech presentation, occurring in approximately 3-5% of term pregnancies, is associated with increased risks of complications during vaginal delivery, including challenges in delivering the aftercoming head, umbilical cord prolapse, birth trauma and neonatal asphyxia. External cephalic version (ECV) is a recommended procedure to reposition the fetus from a non-cephalic to a cephalic presentation, aiming to reduce the risks associated with breech presentation and increase the likelihood of a vaginal delivery. We aimed to determine the impact of neuraxial analgesia on the success rate and safety of ECV by conducting a systematic review and network meta-analysis.

Background: Immunotherapy combined with chemotherapy has become the standard treatment for HER2-negative gastric cancer (GC), but its clinical benefits remain limited, with a median progression-free survival (mPFS) of 6-8 months and median overall survival (mOS) of 15-18 months. These outcomes are particularly poor in patients with CPS < 1. The marked heterogeneity of GC, along with primary and secondary resistance, presents significant clinical challenges and underscores the urgent need for novel therapeutic strategies.

Background: Hepatoid adenocarcinoma of the stomach (HAS) is a rare but highly aggressive subtype of gastric cancer (GC) associated with an unfavorable prognosis, particularly in advanced or metastatic stages. While the standard first-line treatment for advanced GC involves immune checkpoint inhibitors (ICIs) combined with chemotherapy, HAS often shows a poor therapeutic response to this regimen. The hypoxia in the tumor microenvironment is considered a key factor limiting ICI efficacy, and combining hyperbaric oxygen therapy (HBOT) with immunotherapy may offer a synergistic sensitizing effect.

2D Fe-chalcogenides emerge with rich structures, magnetisms, and superconductivities, which spark the growing research interests in the torturous transition mechanism and tunable properties for their potential applications in nanoelectronics. Uniaxial strain can produce a lattice distortion to study symmetry breaking induced exotic properties in 2D magnets. Herein, the anomalous Raman spectrum of 2D tetragonal (t-) and hexagonal (h-) FeTe is systematically investigated via uniaxial strain engineering strategy.

Gastric cancer (GC) poses a significant global health challenge, ranking fifth in incidence and third in mortality among all malignancies worldwide. Its insidious onset, aggressive growth, proclivity for metastasis, and limited treatment options have contributed to its high fatality rate. Traditional approaches for GC treatment primarily involve surgery and chemotherapy.

In order to adapt to complex and changing environments, animals have a wide variety of locomotor forms, which has inspired the investigation of their deformation and driving mechanisms. In this paper, we propose a computational design method for muscle-driven soft robots to satisfy desired deformations, aiming to mimic the deformation behavior of muscle-driven animals in nature. In this paper, we generate the ideal muscle-driven layout for the soft robot by inputting an initial shape and a desired shape, so that it can closely achieve the desired deformation.

Immunotherapy, in the shape of immune checkpoint inhibitors (ICIs), has completely changed the treatment of cancer. However, the increasing expense of treatment and the frequency of immune-related side effects, which are frequently associated with combination antibody therapies and Fc fragment of antibody, have limited the patient's ability to benefit from these treatments. Herein, we presented the therapeutic effects of the plasmid-encoded PD-1 and CTLA-4 scFvs (single-chain variable fragment) for melanoma an optimized intramuscular gene delivery system.

Background: As the lethal bone tumor, osteosarcoma often frequently occurs in children and adolescents with locally destructive and high metastasis. Distinctive kinds of nanoplatform with high therapeutical effect and precise diagnosis for osteosarcoma are urgently required. Multimodal optical imaging and programmed treatment, including synergistic photothermal-chemodynamic therapy (PTT-CDT) elicits immunogenetic cell death (ICD) is a promising strategy that possesses high bio-imaging sensitivity for accurate osteosarcoma delineating as well as appreciable therapeutic efficacy with ignorable side-effects.

Article Synopsis
  • A study reviewed the outcomes of 27 patients who underwent total or high sacrectomy for giant sacral tumors, comparing those who received a pedicled VRAM flap reconstruction to those with conventional wound closure.
  • The VRAM group showed significant benefits including shorter drainage periods, reduced time in bed, and fewer instances of wound infections compared to the conventional closure group.
  • The findings suggest that using a VRAM flap reconstruction technique is more effective for managing large soft-tissue defects post-surgery, resulting in better clinical outcomes.
