Effects of switching from intravitreal injection of aflibercept to faricimab on ocular blood flow in patients with diabetic macular edema.

We assessed the short-term effects of switching from intravitreal aflibercept (IVA) to intravitreal faricimab (IVF) on ocular blood flow in patients with treatment-resistant diabetic macular edema (DME). The medical records of 15 patients with DME who had received IVA injection ≥ 3 months before were retrospectively reviewed. The best-corrected visual acuity, central macular thickness (CMT) on optical coherence tomography, and mean blur rate (MBR) of all disc areas on laser speckle flowgraphy were measured before, 1 week after, and 4 weeks after IVA and IVF, respectively.

A Case of Visual Hallucination With Frontal Lobe Infarction in a Patient With Giant Cell Arteritis.

Giant cell arteritis (GCA) can produce a variety of visual symptoms. Among these, visual hallucinations are rare and are usually accompanied by visual loss. We encountered a 79-year-old female with GCA who presented with visual hallucinations without visual loss.

The relationship between traction spurs, Modic change, vacuum phenomenon, and segmental instability of the lumbar spine.

A thorough understanding of lumbar segmental motion is valuable to treat patients with degenerative lumbar disease, but kinematics associated with indicators of lumbar intervertebral instability [traction spur, Modic changes (MCs) and vacuum phenomenon (VP)] in the lumbar spine have not been well understood. The purpose of this study is to evaluate the relationships between traction spur, MCs and VP to radiographic measurements in the lumbar spine. A total of 525 lumbar discs from L1-2 to L5-S1 of 105 patients were evaluated.

A combined index of waist circumference and muscle quality is associated with cardiovascular disease risk factor accumulation in Japanese obese patients: a cross-sectional study.

Purpose: To identify obese patients at high risk of cardiovascular disease (CVD) using a combined index of obesity and sarcopenia.

Methods: In this cross-sectional study, we firstly conducted analysis of covariance to select each index most associated with the CVD risk score, the number of concomitant CVD risk factors, among obesity- (body mass index, percentage body fat, or waist circumference [WC]) and sarcopenia-evaluated indices (skeletal muscle mass index, handgrip strength, or muscle quality [MQ]), respectively in 188 Japanese obese patients (BMI ≥ 25 kg/m, 73 men and 115 women). Next, we conducted multivariate logistic regression analysis to compare the four groups (Group A-D) classified by medians of the selected indices.

Comparative study of commercial protocols for high recovery of high-purity mesenchymal stem cell-derived extracellular vesicle isolation and their efficient labeling with fluorescent dyes.

The extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) can be used as carriers for therapeutic molecules and drugs to target disordered tissues. This aimed to compare the protocols used for isolation of MSC-derived EVs by comparing EV collection conditions and three commercial purification kits. We also determined appropriate fluorescent dyes for labeling EVs.

Association of protein tyrosine phosphatase 1B gene polymorphism with the effects of weight reduction therapy on bodyweight and glycolipid profiles in obese patients.

Aims/introduction: Weight reduction therapy is the primary treatment to prevent complications of obesity, such as lifestyle diseases and cardiovascular disease; however, to date, useful methods and genetic factors for predicting the outcomes of weight reduction therapy in obese patients have not been established. Protein tyrosine phosphatase 1B (PTP1B), a negative regulator for insulin and leptin signaling, potentially modulates glucose and energy homeostasis. This study aimed to investigate the contribution of PTPN1 polymorphisms on weight reduction and diabetes in obese Japanese patients.

Review of the first comprehensive outpatient parenteral antimicrobial therapy program in a tertiary care hospital in Japan.

Objectives: The infectious diseases team at Kameda Medical Center, Japan, implemented a new outpatient parenteral antimicrobial therapy (OPAT) program in July 2012 and expanded the program with the support of home care services. This study reviews the OPAT program after 5.5 years of operation.

Sulfated Purine Alkaloid Glycosides from the Pupal Case Built by the Bruchid Beetle Bruchidius dorsalis Inside the Seed of Gleditsia japonica.

Three new sulfated isoguanine alkaloid glycosides, designated as saikachinoside A monosulfate (1), saikachinoside A disulfate (2), and locustoside B disulfate (3), have been isolated from the pupal case of the wild bruchid seed beetle Bruchidius dorsalis (Chrysomelidae, Bruchinae) infesting the seed of Gleditsia japonica Miq. (Fabaceae). Their structures were determined by spectroscopic methods and the inhibitory activity of 2 and 3 against acid phosphatase was evaluated.

Can the Amount of Interventions during the Convalescent Phase Predict the Achievement of Independence in Activities of Daily Living in Patients with Stroke? A Retrospective Cohort Study.

Background: This study aimed to evaluate the diagnostic performance of the amount of physical, occupational, and speech therapy intervention and optimal timing necessary for activities of daily living (ADL) independence in patients with stroke.

Method: Patients (N = 441) with stroke admitted to the convalescent rehabilitation ward were classified into an early intervention or a nonearly intervention group on the basis of the duration from the date of onset to date of hospital admission. Logistic regression model was used to identify factors influencing independence in ADL in both groups.

Chemokine (C-X-C motif) ligand 1 is a myokine induced by palmitate and is required for myogenesis in mouse satellite cells.

Aim: The functional significance of the myokines, cytokines and peptides produced and released by muscle cells has not been fully elucidated. The purpose of this study was to identify a myokine with increased secretion levels in muscle cells due to saturated fatty acids and to examine the role of the identified myokine in the regulation of myogenesis.

Methods: Human primary myotubes and mouse C2C12 myotubes were used to identify the myokine; its secretion was stimulated by palmitate loading.

Hyperglycemia and Inflammatory Property of Circulating Monocytes are Associated with Inflammatory Property of Carotid Plaques in Patients Undergoing Carotid Endarterectomy.

Aim: This study aims to determine the association between glucose metabolism and proinflammatory/anti-inflammatory properties of circulating monocytes or those of carotid plaques in patients who underwent carotid endarterectomy.

Methods: Clinical characteristics and expression levels of proinflammatory/anti-inflammatory markers in circulating monocytes/carotid plaques were examined in 12 patients with diabetes and 12 patients without diabetes.

Results: Circulating monocytes from patients with diabetes revealed higher tumor necrosis factor (TNF)-α and lower interleukin (IL)-10 expression levels compared with those from patients without diabetes, which was also observed in carotid plaques from patients with diabetes.

Differential effects of GLP-1 receptor agonist on foam cell formation in monocytes between non-obese and obese subjects.

Objective: Monocytes/macrophages (Mϕ) transform into foam cells in the presence of oxidized-LDL (ox-LDL), releasing inflammatory mediators. The antiatherogenic role of a dipeptidyl peptidase-4 inhibitor is mediated, in part, through improving the unbalance of inflammatory (M1)/anti-inflammatory (M2) phenotypes in monocytes. In this study, we examined differential regulation of glucagon-like peptide-1 receptor (GLP-1R) signaling for antiatherogenesis in monocytes/Mϕ from normal-weight control subjects and obese patients.

Serum free thyroxine levels are associated with the efficacy of weight reduction therapy in obese female patients.

Thyroid function is strongly associated with obesity. The aim of this study is to investigate whether serum free thyroxine (FT4) and/or thyrotropin (TSH) levels are associated with the efficacy of weight reduction therapy in obese patients. We enrolled a total of 283 obese patients and cross-sectionally investigated the association of serum FT4 and/or TSH levels with metabolic features.

[Outpatient Parenteral Antimicrobial Therapy (OPAT) with Elastomeric Pumps in Collaboration with Home-visit Nursing Services in Japan: Experience of the First 10 Patients].

In 2014, we reported the first trial based on outpatient parenteral antimicrobial therapy (OPAT) with continuous infusions in Japan. Following this, we found many patients who were eligible for OPAT but could not undertake it owing to difficulties in accessing the clinic daily. To overcome this problem, we created a model in collaboration with visiting nursing stations and started providing OPAT with the services.
