Background: A phase II clinical trial of the comparison between eribulin plus gemcitabine (EG) and paclitaxel plus gemcitabine (PG) as first-line chemotherapy for patients with metastatic breast cancer (MBC) found that the EG regimen was less neurotoxic, but was similar in efficacy to the PG regimen. In the present study, we analyzed functional assessment of cancer therapy-taxane (FACT-Taxane) questionnaires from patients in this clinical trial to determine their quality of life (QoL). Methods: QoL was assessed using the Korean version of the FACT-Taxane questionnaires. After baseline assessment, QoL was assessed every 2 cycles for 12 cycles and every 3 cycles thereafter. The linear mixed model was used to evaluate the difference in QoL between the EG and PG arms. Results: Of the 118 enrolled patients, 117 responded to the FACT-Taxane questionnaires at baseline, 1 in the PG arm did not. Baseline QoL scores were not different between the EG and PG arms. During treatment, taxane subscale scores were significantly higher in the PG arm than in the EG arm after 2-13 cycles of chemotherapy (all P imen delayed and decreased neuropathy as compared with the PG regimen. Therefore, eribulin would be a reasonable substitute for paclitaxel as first-line chemotherapy for MBC.

背景与目的一项比较艾日布林联合吉西他滨(eribulin plus gemcitabine,EG)或紫杉醇联合吉西他滨(paclitaxel plus gemcitabine,PG)作为转移性乳腺癌(metastatic breast cancer,MBC)患者一线化疗方案的II期临床试验发现,EG方案的神经毒性较低,但疗效与PG方案相似。在本研究中,我们分析了该临床实验中的癌症患者生命质量测评量表–紫杉烷(functional assessment of cancer therapy-taxane,FACT-Taxane)问卷评分以确定他们的生活质量(quality of life,QoL)。方法使用韩国版的FACT-Taxane问卷评估QoL。在评估基线之后,前12个疗程中每2个疗程评估1次QoL,之后每3个疗程评估1次QoL。使用线性混合模型评估EG组和PG组QoL的差异。结果在118例入组患者中,117例在基线时回复了FACT-Taxane问卷,PG组中有1例患者没有回复。EG组和PG组之间的基线QoL评分没有差异。在治疗期间,除了第11个疗程外,在第2–13个化疗疗程后,PG组紫杉烷亚量表评分显著高于EG组(均P<0.05)。神经病变特异性分析显示PG组患者的神经病症状比EG组患者更早出现且更严重(P<0.001)。结论在我们的QoL分析中,与PG方案相比,EG方案延迟并减少神经病变的发生。因此,艾日布林是MBC一线化疗药物紫杉醇的合理替代品。

Elevating the charge cut-off voltage beyond traditional 4.2 V is a commonly accepted technology to increase the energy density of Li-ion batteries(LIBs) but the risk of Li-dendrites and fire hazard increases as well. The use of ambi-functional additive, which forms stable solid electrolyte interphase(SEI) simultaneously at both cathode and anode, is a key to enabling a dendrites-free and well-working high-voltage LIB. Herein, a novel ambi-functional additive, pentaerythritol disulfate(PEDS), at 1 wt% without any other additive is demonstrated. We show the feasibility and high impacts of PEDS in forming lithium sulfateincorporated robust SEI layers at NCM523 cathode and graphite anode in 1 Ah-level pouch cell under4.4 V, 25 °C and 0.1 C rate, which mitigates the high-voltage instability, metal-dissolution and cracks on NCM523 particles, and prevents Li-dendrites at graphite anode. improved capacity retention of 83%after 300 cycles is thereby achieved, with respect to 69% with base electrolyte, offering a promising path toward the design of practical high-energy LIBs.

Bezoars are concretions of indigestible materials in the gastrointestinal tract. It generally develops in patients with previous gastric surgery or patients with delayed gastric emptying. Cases of periampullary duodenal divericular bezoar are rare. Clinical manifestations by a bezoar vary from no symptom to acute abdominal syndrome depending on the location of the bezoar. Biliary obstruction or acute pancreatitis caused by a bezoar has been rarely reported. Small bowel obstruction by a bezoar is also rare, but it is a complication that requires surgery. This is a case of acute pancreatitis and subsequent duodenal obstruction caused by a large duodenal bezoar migrating from a periampullary diverticulum to the duodenal lumen, which mimicked pancreatic abscess or microperforation on abdominal computerized tomography. The patient underwent surgical removal of the bezoar and recovered completely.
