Overwintering at multiple life stages in Schizotetranychus shii (Acari: Tetranychidae), a specialist of evergreen chinquapin.

Spider mites (Acari: Tetranychidae) overwinter as eggs or adult females, but some do so as multiple life stages on evergreen hosts. However, proximate factors influencing such overwintering stages remain poorly understood. This study investigated photoperiodic responses and life-stage compositions during winter in a population of Schizotetranychus shii, a specialist of Japanese chinquapin (Fagaceae).

Efficacy of liposomal irinotecan + 5-FU/LV vs. S-1 in gemcitabine-refractory metastatic pancreatic cancer: a real-world study using inverse probability of treatment weighting.

Background: S-1 monotherapy had previously been widely used as a second-line treatment for pancreatic cancer (PC) after gemcitabine-based chemotherapy mainly in Japan. Based on the results of the NAPOLI-1 trial, the recommended second-line therapy is now liposomal irinotecan plus fluorouracil/folinic acid (nal-IRI + 5-FU/LV). However, there have been no studies comparing nal-IRI + 5-FU/LV therapy with S-1 monotherapy.

Dexamethasone is non-inferior to antihistamine plus dexamethasone premedication in preventing ramucirumab plus nab-paclitaxel infusion-related reactions in gastric cancer: a multicenter retrospective study.

Purpose: Ramucirumab (RAM) is recommended as premedication with H-receptor antagonists (HRA) to prevent infusion-related reactions (IRRs). However, RAM is a human antibody with a low incidence of IRRs. We evaluated the noninferiority of non-HRA (dexamethasone [DEX] alone) premedication to HRA (plus DEX) premedication in terms of IRRs in patients with gastric cancer receiving RAM plus nanoparticle albumin-bound paclitaxel (nab-PTX).

Successful myomectomy using barbed sutures at 15 weeks of gestation: A case report.

To date, there are no reports on the use of barbed sutures in myomectomy during pregnancy. Herein, successful laparotomic myomectomy at 15 weeks of gestation using barbed sutures is described. A 38-year-old pregnant woman with a large myoma (16 × 11 cm) underwent myomectomy at 15 weeks and 4 days of gestation because of strong pain at the myoma site, a high level of inflammatory markers with degeneration of uterine fibroids, and severe anemia caused by denaturation of myoma.
