Implication of perineural invasion in patients with stage II gastric cancer.

Background: Perineural invasion (PNI) is regarded as a prognostic factor for patients with GC. However, the significance of PNI in patients with stage II GC remains unclear. This study aimed to investigate the clinical implication of PNI in patients with stage II GC undergoing curative resection.

Elderly patients with stage II gastric cancer do not benefit from adjuvant chemotherapy.

Background: With the aging of the population, the burden of elderly gastric cancer (EGC) increases worldwide. However, there is no consensus on the definition of EGC and the efficacy of adjuvant chemotherapy in patients with stage II EGC. Here, we investigated the effectiveness of adjuvant chemotherapy in defined EGC patients.

Compliance with Oral Nutritional Supplementation among Gastric Cancer Patients at Nutritional Risk: A Cross-Sectional Study.

Aims: To explore compliance with oral nutritional supplementation (ONS) and to identify the risk factors for noncompliance among gastric cancer patients based on the health belief model (HBM).

Methods: This prospective, observational study included gastric cancer patients at nutritional risk who were prescribed ONS from July to September 2020. Demographic factors, clinical factors, ONS-related factors, social factors and variables derived from the HBM were collected.

Spontaneous Adsorption of Graphene Oxide on Multiple Polymeric Surfaces.

The controllable integration of low-dimensional nanomaterials on solid surfaces is pivotal for the fabrication of next-generation miniaturized electronic and optoelectronic devices. For instance, organization of two-dimensional (2D) nanomaterials on polymeric surfaces paves the way for the development of flexible electronics for applications in wearable devices. Nevertheless, the understanding of the molecular interactions between these nanomaterials and the polymeric surfaces remains limited, which impedes the rational design of 2D nanomaterial-based functional coatings.

Hydrogel-Mediated Mineralization Generates Oriented Crystalline Films Comprising Granular-Rhombohedral Heterogeneous Structures.

Gel-mediated crystallization is a common system to produce self-organized materials, which is fundamental to the development of bottom-up approaches to functional complex materials. Mineralization in hydrogel matrices nevertheless remains empirical in the generation of crystallization products with tailored heterogeneous structures. We demonstrate that the employment of the hydrogels with proper cationic diffusivity can trigger the consecutive growth of oriented, granular-rhombohedral heterogeneous structures.

[Complications analysis of subcutaneous venous access port for chemotherapy in patients with gastrointestinal malignancy].

Objective: To describe and analyze the complications of subcutaneous venous access port for patients with gastrointestinal malignancy.

Methods: Data of 1 912 patients with gastrointestinal malignancy who accepted chemotherapy in our department via subcutaneous venous access ports, including 127 cases in upper arm, 865 cases in subclavicular vein and 920 cases in internal jugular vein, from June 2007 to April 2016 were analyzed retrospectively. Associated complications and risk factors were emphatically investigated.
