White Blood Cell Count and Lymphocyte-to-monocyte Ratio as a Screening Tool for Predicting Intravascular Lymphoma in the Differential Diagnosis of Fever of Unknown Origin.

Objective Intravascular large B-cell lymphoma (IVLBCL) is a critical cause of fever of unknown origin (FUO). While a pathological analysis is essential for diagnosing IVLBCL, the indications for an invasive procedure may be ascertained using easy, non-invasive tests. The lymphocyte-to-monocyte ratio (LMR) can reportedly predict the diagnosis of malignant lymphoma in patients with lymphadenopathy; however, its clinical utility in predicting an IVLBCL diagnosis in patients with FUO remains to be elucidated.

Cytotoxicity of norstictic acid derivatives, a depsidone from Nyl.

Structural modifications in lichen phenolic compounds have been one of the tools to potentiate their biological activity. In the present work, seven alkyl derivatives of norstictic acid were prepared and evaluated against eight cell lines. Norstictic acid was isolated from the lichen and the alkyl derivatives were obtained through reactions with alcohols.

Phase II study of ramucirumab and docetaxel for previously platinum-treated patients with non-small cell lung cancer and malignant pleural effusion (PLEURAM study).

Background: The prognosis of patients with lung cancer and malignant pleural effusion (MPE) caused by carcinomatous pleurisy is poor. Chemical pleurodesis is commonly performed clinically, however, often has a high failure rate. Furthermore, prolonged sustained drainage and delayed introduction of systemic chemotherapy could increase the risk of worsening the Eastern Cooperative Oncology Group Performance Status (ECOG PS) in the treatment of patients with non-small cell lung cancer (NSCLC).

Enzymatic Cleavage of Double-Stranded DNA-Encoded Libraries (DELs) to Single-Stranded DELs with Compounds at the 3' End: Its Application in Photo-Crosslinking Selection.

DNA-encoded library (DEL) technology is a crucial tool in pharmaceutical research, rapidly identifying compounds that bind to a target of interest from an extensive pool of compounds. In this study, we propose a new method for generating single-stranded DELs (ssDELs) with compounds at the 3' end. The introduction of uniquely designed hairpin-shaped headpieces containing deoxyuridine (NC-HP) and the use of a cleavage enzyme facilitate the conversion from double-stranded DELs (dsDELs) to such ssDELs.

Oxytocin-induced increases in cytokines and clinical effect on the core social features of autism: Analyses of RCT datasets.

Although oxytocin may provide a novel therapeutics for the core features of autism spectrum disorder (ASD), previous results regarding the efficacy of repeated or higher dose oxytocin are controversial, and the underlying mechanisms remain unclear. The current study is aimed to clarify whether repeated oxytocin alter plasma cytokine levels in relation to clinical changes of autism social core feature. Here we analyzed cytokine concentrations using comprehensive proteomics of plasmas of 207 adult males with high-functioning ASD collected from two independent multi-center large-scale randomized controlled trials (RCTs): Testing effects of 4-week intranasal administrations of TTA-121 (A novel oxytocin spray with enhanced bioavailability: 3U, 6U, 10U, or 20U/day) and placebo in the crossover discovery RCT; 48U/day Syntocinon or placebo in the parallel-group verification RCT.

Factors associated with cancer disclosure in adolescent and young adult cancer survivors: An integrative review from the social-ecological model perspective.

Purpose: Young cancer survivors ("young survivors") may need to disclose their cancer experiences to reintegrate into society. In such cases, the recognition of social support through the disclosure of cancer experiences may prevent potential social disadvantages． This review aimed to describe the motivations, strategies and outcomes, and benefits and disadvantages of disclosure in young survivors based on the social-ecological model (SEM) to identify the support survivors need when disclosing their cancer experiences.

Methods: Using the integrated review methodology, we systematically searched six databases in English and Japanese as well as searched the reference lists of the selected studies.

Bone metastasis manifested 52 years after resection of an apparently benign paraganglioma: A case report.

Paraganglioma is derived from the paraganglia tissue in the neck, along the sympathetic trunk, and in the pelvis. Paraganglioma has malignant potential and can metastasize to remote organs such as the liver, lungs, and bones. Most metachronous metastases occur within several years after the initial diagnosis of paraganglioma.

A retrospective analysis of the safety of tacrolimus use and its optimal cut-off concentration during pregnancy in women with systemic lupus erythematosus: study from two Japanese tertiary referral centers.

Background: Tacrolimus is one of the major treatment options for systemic lupus erythematosus (SLE) and is considered to be a pregnancy-compatible medication. Since little is known about tacrolimus safety during pregnancy complicated by SLE, this study was designed.

Methods: We included SLE pregnant patients who were followed up at two Japanese tertiary referral centers.

Mapping of Purkinje-related ventricular arrhythmias by a multispline catheter with small and close-paired electrodes: Comparison with conventional catheters.

Background: Precise mapping of the Purkinje fiber network is essential in catheter ablation of Purkinje-related ventricular arrhythmias (PrVAs). We sought to evaluate the mapping ability of a multi-spline duodecapolar catheter (PentaRay) for PrVAs.

Methods: Mappings of Purkinje fibers by PentaRay catheters were compared with those by conventional mapping catheters in consecutive patients undergoing catheter ablation of PrVAs from 2015 to 2022.

Prevalence, treatment status, medical costs, quality of life, and productivity loss in Japanese adult patients with anemia: a real-world database study.

Aims: To investigate the prevalence, treatment status, and effect of anemia on medical costs, quality of life (QOL), and productivity loss in Japan.

Methods: This cross-sectional study used a database containing claims, health check-ups, and questionnaire data. Adults with hemoglobin data at 2020 check-ups were included.

Measuring fluctuating dynamics of sparsely crosslinked actin gels with dual-feedback nonlinear microrheology.

We investigate the fluctuating dynamics of colloidal particles in weakly crosslinked F-actin networks with optical-trap-based microrheology. Using the dual-feedback technology, embedded colloidal particles were stably forced beyond the linear regime in a manner that does not suppress spontaneous fluctuations of particles. Upon forcing, a particle that was stably confined in a cage made of the network's crosslinks started to intermittently jump to the next caging microenvironments.

Association of body size distortion with low body mass index in female patients with nontuberculous mycobacterial lung disease.

Background: We have previously reported that female patients with nontuberculous mycobacterial lung disease (NTM-LD) are thinner and eat less than healthy controls. Therefore, we hypothesized that their thinness is associated with body size misperception. The aim of this study was to clarify whether patients' body size perception (BSP) is associated with body mass index (BMI) independent of potential confounders.

Acceleration of the Deamination of Cytosine through Photo-Crosslinking.

Herein, we report the major factor for deamination reaction rate acceleration, i.e., hydrophilicity, by using various 5-substituted target cytosines and by carrying out deamination at high temperatures.

Proportion of biopsy specimens containing a tumor when compared to all biopsy specimens by transbronchial biopsy.

Background: The lung cancer biopsy specimens obtained by endobronchial ultrasound-guide sheath (EBUS-GS) trans lung biopsy occasionally do not contain cancer cells. It is a problem that there is a possibility that they may not contain cancer cells.

Aim Of The Study: To investigate the proportion of biopsy specimens containing cancer cells in total biopsy specimens.

Concerted primary proton transfer reactions in a thermophilic rhodopsin studied by time-resolved infrared spectroscopy at high temperature.

The primary proton transfer reactions of thermophilic rhodopsin, which was first discovered in an extreme thermophile, Thermus thermophilus JL-18, were investigated using time-resolved Fourier transform infrared spectroscopy at various temperatures ranging from 298 to 343 K (25 to 70 °C) and proton transport activity analysis. The analyses were performed using counterion (D95E, D95N, D229E, and D229N) and proton donor mutants (E106D and E106Q) as well. First, the initial proton transfer from the protonated retinal Schiff base (PRSB) to D95 was identified.

Tall P-waves in inferior leads: A case of coexisting ectopic rhythm and atrial fibrillation arising from the superior vena cava.

Suppression of atrial fibrillation (AF) arising within the superior vena cava (SVC) requires SVC electric isolation (SVCI) without sinus node (SN) injury. If an ectopic rhythm and AF trigger coexist within the SVC, the intra-SVC ectopic rhythm complicates the pre-SVCI search for the SN. This coexistence is without precedent; however, it is important to carefully locate the SN to prevent injury during SVCI.

A double-blinded, randomized controlled clinical trial of hydrogen inhalation therapy for idiopathic sudden sensorineural hearing loss.

Background: Hydrogen (H) has been reported to be effective in reducing hearing loss due to several causes in animal studies. However, no study has examined the effectiveness of H in treating hearing loss in humans. Thus, we investigated whether H is effective for the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL).

Anti-glomerular basement membrane diseases and thrombotic microangiopathy treated with rituximab.

A 68-year-old male patient presented with a 2-week history of malaise and anuria. Renal replacement therapy with haemodialysis was begun for acute kidney injury. His anti-glomerular basement membrane (anti-GBM) antibody titre was 3060 U/ml.

Late reversible complete atrioventricular block and PR interval normalization after antegrade slow pathway ablation for atrioventricular nodal re-entrant tachycardia with pre-existing PR prolongation.

Unlabelled: Late complete atrioventricular block (CAVB) is a rare periprocedural complication in the treatment of atrioventricular (AV) nodal re-entrant tachycardia. However, it can necessitate permanent pacemaker implantation. We present a case of late CAVB that developed during the periprocedural period.

Evaluation of the social skills of low birthweight infants using the Interaction Rating Scale.

[Purpose] This study aimed to examine, using the Interaction Rating Scale, the effect of social skills at 18 months of life on the subsequent development of low birthweight infants. [Participants and Methods] The study participants were made up of a total of 23 infants who were admitted to the neonatal intensive care unit of Hospital A and whose developmental indexes were followed up at the outpatient clinic for up to 3 years of age. The survey was conducted twice in each infant, at a corrected age of 18 months and at 36 full months of age.

Endogenous oxytocin levels in extracted saliva elevates during breastfeeding correlated with lower postpartum anxiety in primiparous mothers.

Background: Breastfeeding in the early postpartum period is expected to have mental benefits for mothers; however, the underlying psychobiological mechanisms remain unclear. Previously, we hypothesized that the release of oxytocin in response to the suckling stimuli during breastfeeding would mediate a calming effect on primiparous mothers, and we examined salivary oxytocin measurements in primiparous mothers at postpartum day 4 using saliva samples without extraction, which was erroneous. Thus, further confirmation of this hypothesis with a precise methodology was needed.
