Discovery of a Phosphodiesterase 7A Inhibitor of High Isozyme Selectivity Exhibiting Anti-Osteoporotic Effects.

Phosphodiesterases (PDEs) have drawn attention due to their critical roles in physiological and pathological conditions. Many research groups have studied these hydrolytic enzymes to develop new drugs, including apremilast as a PDE4 inhibitor and sildenafil as a PDE5 inhibitor. Targeting PDE7 has also been deemed a rational strategy to ameliorate autoimmune conditions.

Effectiveness for remission maintenance rate and safety of different rituximab regimens for treating anti-neutrophil cytoplasmic antibody-associated vasculitis in Japan: a J-CANVAS study.

Rituximab (RTX) has been reported to effectively maintain remission in anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV). In this multicenter study involving 57 patients who achieved remission after 24 weeks, we evaluated the effectiveness of RTX in maintaining remission in patients with AAV. Patients were divided into three groups based on RTX administration: continuous, induction phase-only, and maintenance phase-only groups.

Utility of Duplex Ultrasound in the Diagnosis and Treatment of Functional Popliteal Artery Entrapment Syndrome.

A 19-year-old female presented with intermittent claudication without anatomical abnormality in the popliteal fossa on magnetic resonance imaging and computed tomography. However, duplex ultrasound (DUS) showed compression of the popliteal artery (PA) and vein during plantarflexion and dorsiflexion. She was diagnosed with functional PA entrapment syndrome (PAES) and underwent resection of the plantaris and gastrocnemius muscles using DUS with stress maneuvers, which relieved the symptoms.

Importance of Successful Revascularization in Acute Limb Ischemia: Sub-Analysis From the RESCUE ALI Trial.

Background: This study aimed to assess the 1-year clinical outcomes and predictors of technical success in acute limb ischemia (ALI) treatment.

Methods: A sub-analysis of the REtroSpective multiCenter study of endovascUlar or surgical intErvention for ALI (RESCUE ALI) study involved 185 patients with ALI and technical success (n = 131) or failure (n = 54) treated via surgical, endovascular, or hybrid revascularization between January 2015 and August 2021. The primary endpoint was 1-year amputation-free survival (AFS), and the secondary endpoints included preoperative complications and 1-year reintervention.

Manipulation and analysis of large DNA molecules by controlling their dynamics using micro- and nano-gaps.

Manipulation and analysis methods for large DNAs are critical for epidemiological, clinical, diagnostic, and fundamental research on bacteria, membrane vesicles, plants, yeast, and human cells. However, the physical properties of large DNAs often challenge their manipulation and analysis with high accuracy and speed using the conventional methods such as gel electrophoresis and column-based methods. This review presents the approaches that leverage micrometer- and nanometer-sized gaps within microchannels to control the dynamics and conformations of large DNAs, thereby overcoming these challenges.

Methods And Analysis: This prospective multicentre observational study included patients with ACE, aged 5-35 years, who used DD within 1 year of onset and were followed up for clinical findings and instructed use of DD. The outcomes were classified into four groups: cured, improved, unchanged and worsened.

Autonomic disorder in systemic lupus erythematosus: autoimmune autonomic ganglionopathy.

The pathomechanisms of autonomic disorders in systemic lupus erythematosus (SLE) remain unclear. We herein report a patient with SLE who developed autonomic disorders presumably caused by autoimmune autonomic ganglionopathy (AAG). A 42-year-old woman with SLE under treatment with corticosteroids and hydroxychloroquine was admitted for recurrence of SLE with thrombocytopenia and nephritis.

The impact of angiographic pedal circulation status on wound healing in chronic limb-threatening ischemia after bypass surgery.

Objective: In the treatment of chronic limb-threatening ischemia (CLTI), complete wound healing is an important goal. Although foot perfusion status seems to be important for wound healing, the Global Limb Anatomic Staging System (GLASS) of the Global Vascular Guidelines does not include pedal artery status for the staging process due to the lack of sufficient evidence of its importance. This study aimed to clarify the importance of pedal perfusion status after bypass surgery.

Editor's Choice - Impact of Infrapopliteal Revascularisation Establishing In Line Flow to the Wound in Patients with Chronic Limb Threatening Ischaemia.

Objective: This study aimed to determine the impact of infrapopliteal (IP) revascularisation establishing in line flow to the wound (IFW) on wound healing in chronic limb threatening ischaemia (CLTI), using a core laboratory assessment for wounds and in line flow.

Methods: The Wound directed Angiosome RevasculaRIsation apprOach to patients with cRitical limb iSchaemia (WARRIORS) multicentre observational study enrolled patients with CLTI with tissue loss undergoing IP revascularisation in Japan, with scheduled two year follow up. The primary outcome measure was complete wound healing, defined as achievement of complete epithelialisation of all wounds without major amputation.

Effect of Intake of Bifidobacteria and Dietary Fiber on Resting Energy Expenditure: A Randomized, Placebo-Controlled, Double-Blind, Parallel-Group Comparison Study.

subsp. GCL2505 in combination with inulin has been shown to have several health benefits, including an improvement in the intestinal microbiota and a reduction in human visceral fat. Previous studies have suggested that the visceral fat reduction of GCL2505 and inulin may be achieved by improving daily energy expenditure.

Association of Baseline Serum Soluble Tumour Necrosis Factor Receptor Levels with the Response of Rheumatoid Arthritis to Janus Kinase Inhibitor Therapy.

Aim: The aim of this study was to investigate whether cytokines associated with tumour necrosis factor- (TNF-) and interleukin- (IL-) 6 signalling could predict rheumatoid arthritis (RA) clinical remission (CR) with Janus kinase inhibitor (JAKinib) treatment using the Simplified Disease Activity Index (SDAI).

Methods: Eighty-nine patients with RA treated with JAKinibs were enrolled, and their clinical data were collected retrospectively. CR was defined as an SDAI ≤ 3.

Efficacy of anifrolumab in long-term intractable alopecia due to discoid lupus erythematosus.

Alopecia associated with lupus erythematosus is broadly classified into reversible nonscarring alopecia seen in the acute phase, such as worsening of systemic lupus erythematosus (SLE) and cicatricial alopecia seen in chronic cutaneous lupus erythematosus represented by discoid lupus erythematosus (DLE). In DLE-induced alopecia, early therapeutic intervention before developing scarring alopecia is important, but the condition is often resistant to conventional treatment. Anifrolumab (ANI), a novel therapeutic agent for SLE that inhibits Type I interferon activity, has been shown to be effective against acute skin lesions, including alopecia, in patients with SLE.

Retinal hemorrhages and damages from tractional forces associated with infantile abusive head trauma evaluated by wide-field fundus photography.

We evaluated the distribution and types of retinal hemorrhages (RHs) and other damages in eyes with abusive head trauma (AHT). This retrospective, consecutive case series of AHT and non-AHT conditions involved 54 children with AHT, 43 children with head bruises, and 49 children with blunt eye trauma, each of non-AHT supported by reliable witness accounts. RHs and other damage were evaluated using ophthalmoscopy and wide-field fundus photography.

Prognostic factors after open and endovascular repair for infected native aneurysms of the abdominal aorta and common iliac artery.

Objective: Infected native aneurysms (INAs) of the abdominal aorta and iliac arteries are uncommon, but potentially fatal. Endovascular aneurysm repair (EVAR) has recently been introduced as a durable treatment option, with outcomes comparable to those yielded by conventional open repair. However, owing to the rarity of the disease, the strengths and limitations of each treatment remain uncertain.

Systemic exposure to aflibercept after intravitreal injection in premature neonates with retinopathy of prematurity: results from the FIREFLEYE randomized phase 3 study.

Background: There are no data on pharmacokinetics, pharmacodynamics, and immunogenicity of intravitreal aflibercept in preterm infants with retinopathy of prematurity (ROP). FIREFLEYE compared aflibercept 0.4 mg/eye and laser photocoagulation in infants with acute-phase ROP requiring treatment.

Establishment and visual analysis of CBA/J-Pde6b and C3H/HeJ-Pde6b mice.

In CBA/J and C3H/HeJ mice, retinitis pigmentosa is inherited as an autosomal-recessive trait due to a mutation in Pde6b, which encodes cGMP phosphodiesterase subunit b. In these strains, the Y347X mutation in Pde6b leads to the upregulation of cGMP levels, increased Ca influx induces rod death, and the outer segment and rod cells entirely disappeared by 35 days after birth. In the present study, we utilized the clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated (Cas) 9-mediated gene editing to repair the Y347X mutation in CBA/J and C3H/HeJ mice.
