Cartilage degeneration of patellofemoral joint occurs in open wedge high tibial osteotomy, rather than in hybrid closed wedge high tibial osteotomy, during the early postoperative period: A qualitative analysis using MRI T mapping.

Purpose: After high tibial osteotomy, the patella may change position and osteoarthritis of the patellofemoral joint (PFJ) may occur. It was hypothesized that the course of PFJ degeneration would differ between open wedge high tibial osteotomy (OWHTO) and hybrid closed wedge high tibial osteotomy (hybrid HTO). Accordingly, this study aimed to evaluate the qualitative changes in PFJ articular cartilage, during the early postoperative period after OWHTO and hybrid HTO.

Association between early immunophenotypic changes and therapeutic response of belimumab in patients with systemic lupus erythematosus.

Belimumab is a therapeutic medication that inhibits the B-cell-activating factor (BAFF) used for systemic lupus erythematosus (SLE); however, the response sometimes varies among individuals, even when patients are stratified based on general clinical characteristics. Therefore, we focused on immunological phenotypic changes with belimumab, investigated their association with subsequent clinical courses, and sought to identify relevant immunological indicators to stratify patients who would benefit from belimumab. We assessed changes in B and T cell phenotypes, as well as BAFF-related factors, such as levels of BAFF and a proliferation-inducing ligand, and expression of three BAFF receptors: BAFF receptor (BAFF-R), B-cell maturation antigen (BCMA), transmembrane activator and cyclophilin ligand interactor (TACI), in 19 patients with SLE who were treated with belimumab before and 3 months after treatment.

Surgical repair of a posterior left ventricular aneurysm in a 4-year-old boy.

Left ventricular aneurysms are rarely encountered in pediatric patients. A 4-year-old boy was diagnosed with severe mitral regurgitation and a posterior left ventricular aneurysm associated with a viral infection. The aneurysm was surgically resected and plicated longitudinally with a combination of an interrupted mattress and continuous over-and-over sutures with an outer felt reinforcement.

Diabetic nephropathy ameliorated in patients with normal home blood pressure compared to those with isolated high home systolic blood pressure: A 5-year prospective cohort study among patients with type 2 diabetes mellitus.

Background: Using normal home blood pressure (home BP) as a reference, isolated high home systolic blood pressure (IH-home SBP) increases the risk of diabetic nephropathy. However, whether diabetic nephropathy would improve among diabetic patients without IH-home SBP has not been previously assessed.

Methods: This prospective 5-year cohort study of 264 patients with moderate or severe albuminuria investigated the effect of IH-home SBP or normal home BP on the risk of diabetic nephropathy in patients with type 2 diabetes mellitus.

Primary Pulmonary Myxoid Sarcoma with Fusion: A Case Report.

Primary pulmonary myxoid sarcoma is a rare lung sarcoma, mostly involving the central lung and harboring the fusion. We report an exceptional case of primary pulmonary myxoid sarcoma arising in the peripheral lung and harboring an gene fusion. A 67-year-old man presented with a solid nodule in the right lower lobe, and wedge resection was performed.

Successful Endovascular Therapy for Total Occlusion of the Distal Radial and Ulnar Artery with Palmar Artery Lesion in a Patient with Critical Hand Ischemia Associated with Systemic Sclerosis.

Vasculopathy of systemic sclerosis (SSc) is known to lead to severe limb ischemia and is often associated with macrovascular diseases. Revascularization of proximal macrovascular lesions that cause limb ischemia in patients with SSc has been recommended; however, it has rarely been reported for lesions below-the-elbow (BTE) involving the palmar artery. A 66-year-old female patient with SSc experienced critical hand ischemia (CHI) with gangrene of the left third finger that failed to respond to conventional pharmacological treatment.

Predictors of delayed wound healing after simultaneous endovascular treatment and minor forefoot amputation for chronic limb-threatening ischemia with wound infection.

Objectives: To assess wound healing after simultaneous endovascular treatment (EVT) and minor forefoot amputation and identify the predictors of delayed wound healing in patients with chronic limb-threatening ischemia (CLTI) and bacterial infections of the wounds.

Methods: In this single-center retrospective cohort study, we evaluated 79 consecutive limbs with tissue loss from 73 CLTI patients who underwent simultaneous EVT and minor forefoot amputation between November 2017 and May 2020. To estimate the rate of wound healing after the simultaneous procedure, we used the Kaplan-Meier method.

Efficacy of simulation training for beating heart coronary anastomosis using BEAT + YOUCAN simulator.

Background: We sought to evaluate our distributed practice program developed for training for beating heart anastomosis by employing a novel beating heart simulator.

Methods: Eleven trainees watched and reviewed instructional video recordings of coronary anastomosis methods with a BEAT  +  YOUCAN training device, then performed coronary anastomosis procedures under a beating condition. Next, they participated in a four-hour training program developed by faculty surgeons.

Mesectodermal Leiomyoma of the Ciliary Body: A Unique Variant of Leiomyoma with Myogenic and Neurogenic Histological Features.

Mesectodermal leiomyoma of the ciliary body is a rare benign tumor, showing both neurogenic and myogenic characteristics. This tumor typically shows predilection for women of reproductive age. Because it is almost impossible to clinically distinguish this tumor from malignant melanoma, unnecessary eye enucleations have been unfortunately performed.

Actual Situations and Factors Related to Nursing Activities in Supporting the Transition to Homecare Settings for End-Stage Cancer Patients in General Wards in Japan.

This study aimed to investigate actual situations of nursing activities in supporting the transition to homecare settings for end-stage cancer patients and to determine factors related to executing such nursing activities from the perspectives of communication skills and interprofessional collaboration. A cross-sectional study was conducted with 513 nurses who worked at designated cancer care hospitals in Japan. A total of 318 valid responses were obtained (valid response rate: 62.
