Impact of Antiplatelet Therapy on 5-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization in Nonsignificant Obstructive Coronary Artery Disease.

Background: Because the clinical benefit of antiplatelet therapy (APT) for patients with nonsignificant coronary artery disease (CAD) remains poorly understood, we evaluated it in patients after fractional flow reserve (FFR)-guided deferral of revascularization.

Methods And Results: From the J-CONFIRM (Long-Term Outcomes of Japanese Patients with Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), we investigated 265 patients with deferred lesions who did not require APT for secondary prevention of cardiovascular disease. A 2-year landmark analysis assessed the relationship between APT at 2 years and 5-year major cardiac adverse events (MACE: composite of all-cause death, target vessel-related myocardial infarction, clinically driven target vessel revascularization).

Diagnostic performance of linked color imaging for gastric cancer by Helicobacter pylori infection status: A subanalysis of the large-scale, multicenter randomized controlled trial LCI-FIND.

Background: Linked color imaging (LCI) is a new image enhancement technology that facilitates the recognition of subtle differences in mucosal color. In the large-scale, multicenter randomized controlled trial LCI-FIND, LCI demonstrated good diagnostic performance for the detection of tumor lesions in the upper gastrointestinal tract. The aim of the present study was to exploratively evaluate the diagnostic performance of LCI according to H.

Sex Differences in 5-Year Outcomes After Deferral of Revascularization Following Physiological Coronary Assessment.

The relationship between sex differences and long-term outcomes after fractional flow reserve (FFR)- and instantaneous wave-free ratio (iFR)-guided deferral of revascularization has yet to be elucidated. From the J-CONFIRM registry (long-term outcomes of Japanese patients with deferral of coronary intervention based on FFR in a multicenter registry), this study included 432 lesions from 385 patients (men, 323 lesions in 286 patients; women, 109 lesions in 99 patients) with paired data of FFR and iFR. The primary endpoint was the cumulative 5-year incidence of target vessel failure (TVF), including cardiac death, target vessel-related myocardial infarction, and clinically driven target vessel revascularization.

Characterization of residual cancer by comparison of a pair of organoids established from a patient with esophageal squamous cell carcinoma before and after neoadjuvant chemotherapy.

Neoadjuvant chemotherapy (NAC) followed by surgery is a standard approach for management of locally advanced esophageal squamous cell carcinoma (ESCC). Patients who do not respond well to NAC have a poor prognosis. Despite extensive research, the mechanisms of chemoresistance in ESCC remain largely unknown.

A characteristic of olfactory function in four types of dementia and non-dementia subjects using smell identification test.

Background: For those outpatients who were consulted for memory loss, the Japanese version of University of Pennsylvania Smell Identification Test (UPSIT-J) was performed to examine olfactory function. In the same way, the revised version of Hasegawa Dementia Scale, Mini Mental State Examination, Clinical Dementia Rating and brain magnetic resonance imaging were used to investigate the cognitive function. In the present study, we evaluated the olfactory function of elderly subjects, including those with dementia, by means of UPSIT-J and we examined their characteristics.

Prognostic Impact of Renal Function on 5-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization.

Background Chronic kidney disease (CKD) might influence fractional flow reserve (FFR) value, potentially attenuating its prognostic utility. However, few large-scale data are available regarding clinical outcomes after FFR-guided deferral of revascularization in patients with CKD. Methods and Results From the J-CONFIRM registry (Long-Term Outcomes of Japanese Patients With Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), 1218 patients were divided into 3 groups according to renal function: (1) non-CKD (estimated glomerular filtration rate ≥60 mL/min per 1.

Association of immune-related expression profile with sensitivity to chemotherapy in esophageal squamous cell carcinoma.

Neoadjuvant chemotherapy (NAC) followed by surgery is one of the standard therapeutic approaches in Japan for patients with locally advanced esophageal carcinoma. Recently, the JCOG1109 study revealed that NAC with docetaxel, cisplatin and 5-fluorouracil (5-FU) (DCF-NAC) is superior to NAC with cisplatin and 5-FU, and has now become the standard preoperative chemotherapy. Using a microarray system, we have previously investigated the expression profiles of endoscopic biopsy samples from patients with esophageal squamous cell carcinoma (ESCC) before DCF-NAC (preNAC) and identified 17 molecules as biomarkers predictive of a pathologically complete response to DCF-NAC.

Examination and reliability of measuring muscle strength of ankle plantar flexion with knee extended.

[Purpose] A hand-held dynamometer (HHD) is less expensive than the isokinetic muscle strength measurement device, and research using HHD is gradually increasing. However, measurement is performed only at a low muscle strength level at which the heel does not take off or heel detachment occurs; therefore, fixation of the foot becomes a problem. This study aimed to determine the validation of measuring ankle plantar flexion strength (with the knee extended) using HHD.

Patient-Derived Ex Vivo Cultures and Endpoint Assays with Surrogate Biomarkers in Functional Testing for Prediction of Therapeutic Response.

Prediction of therapeutic outcomes is important for cancer patients in order to reduce side effects and improve the efficacy of anti-cancer drugs. Currently, the most widely accepted method for predicting the efficacy of anti-cancer drugs is gene panel testing based on next-generation sequencing. However, gene panel testing has several limitations.

Five-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization in Infarct-Related Artery Lesions.

Background: Little evidence is available about the long-term safety of fractional flow reserve (FFR)-guided deferral of revascularization in infarct-related artery (IRA) lesions, especially when measuring FFR in the late setting after myocardial infarction (MI). This study aimed to assess the long-term outcomes after deferral of revascularization in IRA lesions based on FFR assessed in the late phase of post-MI.

Methods: From the J-CONFIRM registry (Long-Term Outcomes of Japanese Patients With Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), data on 1447 lesions (1263 patients) were divided into 2 groups: the IRA and non-IRA groups.

Characteristics of people seeking consultation after progressing to severe dementia: A mixed-method analysis.

Objectives: This explores the characteristics of patients with worsening dementia who did not receive a specialized medical examination or care.

Methods: This study utilized a mixed methods analysis. Of the 2712 people who received the Mini Mental State of Examination (MMSE) at the Community Consultation Center for Citizens with MCI and Dementia between December 2007 and December 2019, 1413 people who scored 23 points or less were included.

Effectiveness of a self-reporting yes/no survey for dementia screening-trial in Fukui, Japan.

Early intervention for dementia patients is extremely important for the prevention of dementia. However, so far, it is not clear as to what kind of screening will be useful for the early detection of dementia. We aimed to investigate the relationship between the results of a short self-reporting yes/no survey selected in Kihon Checklist, developed by the Japanese Ministry of Health, Labor and Welfare to identify older adults who are at risk of requiring support/care, and other original items developed by Dementia Prevention Team, Fukui, Japan, and Mini-Mental State Examination (MMSE) scores, and determine the diagnostic efficacy of the self-reporting yes/no survey.

Enhanced phosphorylation of c-Jun by cisplatin treatment as a potential predictive biomarker for cisplatin response in combination with patient-derived tumor organoids.

Despite recent advances in sequencing technology and large-scale drug screenings employing hundreds of cell lines, the predictive accuracy of mutation-based biomarkers is still insufficient as a guide for cancer therapy. Therefore, novel types of diagnostic methods using alternative biomarkers would be highly desirable. We have hypothesized that sensitivity-specific changes in the phosphorylation of signaling molecules could be useful in this respect.

Sansoninto-induced Lung Injury.

A man in his 70s visited our department for dyspnea with pulmonary infiltrate that was unresolved by antibiotics. He had been taking Sansoninto for five years and doubled its dose a month ago. After discontinuing Sansoninto without any additional medications, his symptoms gradually disappeared, and pulmonary infiltration improved.

Influences of Vitamin B Supplementation on Cognition and Homocysteine in Patients with Vitamin B Deficiency and Cognitive Impairment.

Relationship between Food Crushing and Oral Function in Older Adults Requiring Nursing Home Care: A Pilot Study.

We investigated how jelly is crushed and examined the relationship between tongue pressure and tongue food crushing ability among older adults requiring nursing home care. Seventy-two participants were instructed to freely crush the test foods soft jelly (SJ) and hard jelly (HJ). We visually evaluated the crushability of the test food and identified the intraoral tissues (active sites) used to crush the test food.

A low albumin level as a risk factor for transient severe motion artifact induced by gadoxetate disodium administration: A retrospective observational study with free-breathing dynamic MRI and an experimental study in rats.

Objectives: In the arterial phase of gadoxetate disodium administration for dynamic MRI, transient severe motion (TSM) sometimes occurs, making image evaluation difficult. This study was to identify risk factors for TSM in a clinical study, and confirm them and investigate the cause in an animal study.

Methods: A retrospective, single-center, observational study included patients who underwent dynamic MRI using gadoxetate disodium for the first time from April 2016 to September 2019 and free-breathing MRI was performed.

Long-Term Outcomes in Elderly Patients After Deferral of Coronary Revascularization Guided by Fractional Flow Reserve.

Background: Little evidence is available regarding the long-term outcome in elderly patients after deferral of revascularization based on fractional flow reserve (FFR).

Methods and results: From the J-CONFIRM registry (long-term outcomes of Japanese patients with deferral of coronary intervention based on fractional flow reserve in multicenter registry), 1,262 patients were divided into 2 groups according to age: elderly and younger patients (aged ≥75 or <75 years, respectively). The primary endpoint was the cumulative 5-year incidence of target vessel failure (TVF), defined as a composite of cardiac death, target vessel-related myocardial infarction (TVMI), and clinically driven target vessel revascularization (CDTVR).

Background: Little large-scale data is available about the long-term (beyond 3 years) clinical outcomes after fractional flow reserve (FFR)-based deferral of revascularization in clinical practice. We sought to assess the 5-year outcomes after deferral of revascularization based on FFR.

Methods: The J-CONFIRM registry (Long-Term Outcomes of Japanese Patients With Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry) prospectively enrolled 1263 patients with 1447 lesions in whom revascularization was deferred based on FFR from 28 Japanese centers.

Association of guideline-directed medical therapy adherence with outcomes after fractional flow reserve-based deferral of revascularization.

Aims: Guideline-directed medical therapy (GDMT) is essential to prevent future cardiovascular events in chronic coronary syndrome (CCS) patients. However, whether achieving optimal GDMT could improve clinical outcomes in CCS patients with deferred lesions based on fraction flow reserve (FFR) remains thoroughly investigated. We sought to evaluate the association of GDMT adherence with long-term outcomes after FFR-based deferral of revascularization in a real-world registry.

The Changes in Concentration of Cerebral Oxygenated Hemoglobin During Single Event-Related Japanese Shiritori Task in Patients With Major Depression Disorder: Comparison With Healthy Subjects.

Patients with major depressive disorder (MDD) have been reported to show cognitive impairments in attention, cognition control, and motivation. The purpose of this study is to compare and examine the characteristics of frontal and temporal cortical activity in outpatients with MDD during the word production task (Shiritori) using a single event-related Near-Infrared Spectroscopy (NIRS) measurement method that was originally devised. The subjects were 29 MDD patients and 29 age matched healthy controls.

Analyses of the Mode of Action of an Alpha-Adrenoceptor Blocker in Substantia Gelatinosa Neurons in Rats.

To elucidate why naftopidil increases the frequency of spontaneous synaptic currents in only some substantia gelatinosa (SG) neurons, post-hoc analyses were performed. Blind patch-clamp recording was performed using slice preparations of SG neurons from the spinal cords of adult rats. Spontaneous inhibitory and excitatory postsynaptic currents (sIPSCs and sEPSCs, respectively) were recorded.
