Impact of primary prophylaxis by pegfilgrastim in diffuse large B-cell lymphoma treated with R-CHOP.

Febrile neutropenia (FN) and chemotherapy-induced neutropenia (CIN) are common conditions that lead to dose reduction or delayed chemotherapy in patients with diffuse large B-cell lymphoma (DLBCL). Primary prophylaxis (PP) with long-acting granulocyte colony-stimulating factor (G-CSF) was introduced in South Korea in 2014. We aimed to investigate the effects of PP on FN-related hospitalization and death in patients with DLBCL receiving rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP).

Double-Pigtail Drainage Catheter: A New Design for Efficient Pleural Drainage.

: The novel double-pigtail catheter (DPC) has an additional pigtail coiling at the mid-shaft with multiple centripetal side holes. The present study aimed to investigate the advantages and efficacy of DPC in overcoming the complications of conventional single-pigtail catheters (SPC) used to drain pleural effusion. : Between July 2018 and December 2019, 382 pleural effusion drainage procedures were reviewed retrospectively (DPC, = 156; SPC without multiple side holes, = 110; SPC with multiple side holes (SPC + M), = 116).

Postoperative Angular Changes According to Weightbearing in Patients With Moderate to Severe Hallux Valgus.

Hallux valgus is a progressive angular deformity of the big toe, the degree of which is aggravated in weightbearing stance. Hallux valgus and intermetatarsal angles on postoperative weightbearing images are usually larger than those of intraoperative fluoroscopic and immediate postoperative non-weightbearing images. Here, we hypothesized that various angular parameters of hallux valgus would increase postoperatively with weightbearing.

Comparison of surgical outcomes between single versus dual K-wire fixation for unstable distal phalanx fractures.

Distal phalanx fractures are the most common injuries of the hand, and K-wire fixation is commonly performed for unstable fractures. However, there is no consensus regarding the number of K-wires to use in bone fixation. We aimed to compare the results between single and dual K-wire pinning.

Synthesis of substituted triazolyl curcumin mimics that inhibit RANKL-induced osteoclastogenesis.

Some promising new antiresorptive agents of potential utility for treating osteoporosis were uncovered in a curcumin mimics library possessing a substituted triazole moiety, which is synthesized by the Cu(I)-catalyzed Huisgen 1,3-cycloaddition reaction between two azido intermediates (9 and 10) and various alkynes (a-k). A tartarate-resistant acid phosphatase (TRAP) activity assay was carried out with RANKL-induced osteoclastogenesis of mouse monocyte/macrophage RAW264.7 cells; the results indicated that the curcumin mimics derived from intermediate 10 exhibited stronger inhibitory activity than 9.

Association between alcohol consumption and bone strength in Korean adults: the Korean Genomic Rural Cohort Study.

Previous studies have reported an inconsistent relationship between alcohol consumption and bone health. A growing body of research has shown that chronic alcoholism leads to osteopenia and increased incidence of skeletal fractures, but some studies have concluded that alcohol consumption may be associated with higher bone mineral density in elderly populations. However, most studies showing a significant relationship between alcohol consumption and bone status have been in Western countries; and subjects have usually been postmenopausal women.
