Safety and Effectiveness of Exercise-Based Cardiac Rehabilitation for Patients With Atrial Fibrillation Following Radiofrequency Catheter Ablation Therapy: A Systematic Review and Meta-Analysis.

Despite the potential of cardiac rehabilitation (CR) to reduce atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA), its prescription is not routine. We conducted a systematic review and meta-analysis to evaluate the safety and efficacy of CR in this setting. Inclusion criteria comprised randomized controlled trials (RCTs) comparing CR with usual care in patients with AF following RFCA.

Peer Support for Patients With Heart Failure: A Systematic Review and Meta-Analysis.

Peer support, which is given by people with similar life experiences and experiential knowledge, has been shown to be effective for patients with diabetes and mental illness. However, the impact of such peer support on patients coping with heart failure remains indeterminate. The objective of this systematic review and meta-analysis is to scrutinize the potential benefits of peer support for patients with heart failure.

Statistical model of trajectories of reduced mobility in older people with locomotive disorders: a prospective cohort study with group-based trajectory model.

Background: Today we experience "Super-aged society", and a drastic increase in the number of older people needing assistance is an urgent matter for everyone from medical and socio-economical standpoints. Locomotive organ dysfunction due to musculoskeletal disorders is one of the main problems in these patients. Although the concepts of frailty and sarcopenia have been proposed for functional decline, pain remains the main and non-negligible complaint in these of such disorders.

Methods: The present study used a hospital-based database created by JMDC Inc. The JMDC hospital-based database is an epidemiological database that has been storing medical claims and Diagnosis Procedure Combination survey data.

Effects of sleep quality on pain, cognitive factors, central sensitization, and quality of life in patients with chronic low back pain.

Background: Sleep quality in patients with chronic low back pain (CLBP) may affect quality of life (QoL), possibly due to worsening pain, central sensitization (CS), and cognitive factors. However, causal relationship among the factors has not been confirmed yet.

Objective: The purpose of this study was to test the hypothesis that sleep quality in patients with CLBP is attributable to pain, cognitive factors, and CS, and influences QoL, by structural covariance analysis.

Immediate Effects of Mobile Phone App for Depressed Mood in Young Adults with Subthreshold Depression: A Pilot Randomized Controlled Trial.

Background: Preventive interventions for subthreshold depression (StD) are essential to reduce the incidence of major depressive disorder. Our smartphone application presenting positive word stimulation in video (ie, Subliminal Priming with Supraliminal Reward Stimulation, SPSRS) was suggested to improve depressive symptoms in people with StD, although it is unclear whether it can immediately improve depressed mood. This pilot randomized controlled trial (RCT) aimed to investigate the preliminary efficacy of SPSRS application intervention on depressive mood in people with StD.

Multiple colonies of cancer involved in mutual suppression with the immune system.

We study the effects of the immune system on multiple cancer colonies. When cancer cells proliferate, cytotoxic T lymphocytes (CTLs) reactive to the cancer-specific antigens are activated, suppressing the growth of cancer colonies. The immune reaction activated by a large cancer colony may suppress and eliminate smaller colonies.

Mathematical modeling for developmental processes.

We review several mathematical models and concepts in developmental biology that have been established over the last decade. (1) Feedback vertex set: Ascidian embryos contain cells of seven types, and cell fate is controlled by ~100 interacting genes. The "feedback vertex set" of the directed graph of the gene regulatory network consists of a small number of genes.

Clinical features of persistent postural-perceptual dizziness with isolated otolith dysfunction as revealed by VEMP and vHIT findings.

Background: Persistent postural-perceptual dizziness (PPPD) is a relatively new disease entity, with diagnostic criteria published by the Bárány Society. PPPD is often preceded by a peripheral or central vestibular disorder. It is not clear how coexisting deficits due to preceding vestibular disorders affect PPPD symptoms.

Differences in Center for Epidemiologic Studies Depression Scale, Generalized Anxiety Disorder-7 and Kessler Screening Scale for Psychological Distress Scores between Smartphone Version versus Paper Version Administration: Evidence of Equivalence.

The use of electronic patient-reported outcomes has increased recently, and smartphones offer distinct advantages over other devices. However, previous systematic reviews have not investigated the reliability of the Center for Epidemiologic Studies Depression Scale (CES-D), Generalized Anxiety Disorder-7 (GAD-7), and Kessler Screening Scale for Psychological Distress (K6) when used with smartphones, and this has not been fully explored. This study aimed to evaluate the equivalence of the paper and smartphone versions of the CES-D, GAD-7, and K6, which were compared following a randomized crossover design method in 100 adults in Gunma, Japan.

BALB.NCT- is a unique mouse model of hereditary coproporphyria.

In humans, mutations in the coproporphyrinogen oxidase () gene can result in hereditary coproporphyria (HCP), characterized by high levels of coproporphyrin excretion in the urine and feces, as well as acute neurovisceral and chronic cutaneous manifestations. Appropriate animal models for comprehending the precise pathogenesis mechanism of HCP have not been reported that show similarities in terms of gene mutation, reduced CPOX activity, excess coproporphyrin accumulation, and clinical symptoms. As previously discovered, the BALB.

Renal Function in Aged C57BL/6J Mice Is Impaired by Deposition of Age-Related Apolipoprotein A-II Amyloid Independent of Kidney Aging.

Spontaneous and age-related amyloidosis has been reported in C57BL/6J mice. However, the biochemical characteristics of age-related amyloidosis remain unclear. Herein, the age-related prevalence of amyloidosis, the types of amyloid fibril proteins, and the effects of amyloid deposition were investigated in renal function in C57BL/6J mice.

Validity of temporo-spatial characteristics of gait as an index for fall risk screening in community-dwelling older people.

[Purpose] This study aimed to identify kinematic gait indicators for a fall risk screening test through quantitative comparisons of gait characteristics measured using mobile inertial sensors between faller and non-faller groups in a population of community-dwelling older people. [Participants and Methods] We enrolled 50 people aged ≥65 years who used long-term care prevention services, interviewed them to determine their fall history during the past year, and divided them into faller and non-faller groups. Gait parameters (velocity, cadence, stride length, foot height, heel strike angle, ankle joint angle, knee joint angle, and hip joint angle) were assessed using the mobile inertial sensors.

Spectral Reflectance Estimation from Camera Responses Using Local Optimal Dataset.

A novel method is proposed to estimate surface-spectral reflectance from camera responses using a local optimal reflectance dataset. We adopt a multispectral imaging system that involves an RGB camera capturing multiple images under multiple light sources. A spectral reflectance database is utilized to locally determine the candidates to optimally estimate the spectral reflectance.

Life on bottles: Colonisation of macroplastics by freshwater biota.

While rivers are known to be the main vectors of plastics to the sea, it seems surprising that studies on interactions (e.g. colonisation/entrapment and drift) between macroplastics and biota continue to remain largely neglected, notwithstanding they represent unexpected threats to freshwater biota and riverine habitats.

The genetic structure within a single tree is determined by the behavior of the stem cells in the meristem.

Genomic sequencing revealed that somatic mutations cause a genetic differentiation of the cells in a single tree. We studied a mathematical model for stem cell proliferation in the shoot apical meristem (SAM). We evaluated the phylogenetic distance between cells sampled from different portions of a shoot, indicating their genetic difference due to mutations accumulated during shoot elongation.

Objectives: This study investigated the effects of a supervised home-based vestibular rehabilitation program using a booklet on gait function and dizziness in patients with chronic peripheral vestibular hypofunction.

Methods: This was a non-blinded, randomized, controlled trial. Patients (n=42) with chronic peripheral vestibular hypofunction were randomly divided into the vestibular rehabilitation group (VR group; n=20) or the control group (n=22).

Theoretical studies of diverse sexual patterns in marine animals.

Marine animals show diverse and flexible sexual systems. Here, we review several advancements of theoretical studies made in the last decade. (i) Sex change in coral fishes is often accompanied by a long break in reproductive activity.

Macrophages in the reticuloendothelial system inhibit early induction stages of mouse apolipoprotein A-II amyloidosis.

Amyloidosis refers to a group of degenerative diseases that are characterized by the deposition of misfolded protein fibrils in various organs. Deposited amyloid may be removed by a phagocyte-dependent innate immune system; however, the precise mechanisms during disease progression remain unclear. We herein investigated the properties of macrophages that contribute to amyloid degradation and disease progression using inducible apolipoprotein A-II amyloidosis model mice.
