The thermoelectric (TE) materials can transform thermal energy into electrical energy, and polymer TE composites have attracted increasing interest for flexible semiconductors. However, polymer composites suffer from low TE performances due to the low electroconductibility (σ). Herein, grafted conducting networks were fabricated by grafting polypyrrole (PPy) onto the cheap graphene of reduced graphene oxide (rGO) in the bundled micro-tunnel of towel-gourd sponge (TS) fibers. Afterward, the TS powders containing grafted conducting networks were cured by the polydimethylsiloxane (PDMS). The PDMS/TS-rGO-PPy composites exhibited an σ of 74 S/m, thermal conductivity of 0.249 W·m·K, Seebeck coefficient of 84.2 μV/K, and thermoelectric figure of merit of 5.427 × 10 with 10.0 wt % filler loading. Moreover, dynamic TE properties of our composites under tensile loading were investigated. The results show that the grafted conducting network maintained its integrity by interconnection of PPy between adjacent rGO nano-layers.

Purpose: Lumbar puncture is a frequently performed procedure for patients undergoing treatment for acute lymphoblastic leukemia. This brief procedure is frequently performed with sedation in young patients but with only local anesthesia in adults. Adolescent and young adult patients may be cared for by physicians with different training backgrounds and sedation preferences, making the utilization of sedation for lumbar punctures variable among providers.

Purpose: Pancreatectomy patients often experience challenging fluctuations in blood glucose levels; therefore, they require a reliable monitoring system. This study aimed to determine the accuracy and acceptability of a continuous glucose monitoring (CGM) system compared with the intermittent capillary glucose test in patients who have undergone pancreatectomy.
Methods: Thirty non-diabetic pancreatectomy patients participated.

: The state of patients' health following liver transplantation is influenced by a number of factors. To provide personalized nursing care, it is essential to understand the impact that the transplant has had on the patient's life. The primary aim of this study was to examine gender differences in the overall health effect following liver transplantation.
