A Predictive Model for Oral Intake Independence in Dysphagia Treatment.

Objective: One concern for patients suffering from dysphagia is whether their swallowing improves enough to allow oral intake. Predicting oral intake independence would be practical for deciding the treatment strategy, such as swallowing improvement surgeries, at an early stage. This study describes the prognostic factors and predictive method for achieving oral intake independence at discharge from acute care hospitals.

Frameshift Mutation in de novo Small-Cell Neuroendocrine Carcinoma of the Prostate: A Case Report.

A 66-year-old male was diagnosed with cT4N0M1b small-cell neuroendocrine carcinoma of the prostate. Four months after the administration of combined androgen blockade, multiple novel metastatic regions in the lung and liver and progression of bone metastasis were observed. The patient was referred to our hospital because of biochemical and radiographic progression after four cycles of docetaxel as a first-line therapy for castration-resistant prostate cancer.

Development of the Japanese Parenting Style Scale and examination of its validity and reliability.

Parenting is an essential factor affecting child development. Therefore, several studies have focused on individual differences in parenting (i.e.

Analysis of subgingival microbiota in monozygotic twins with different severity and progression risk of periodontitis.

The study aims to reveal the composition of subgingival bacteria in monozygotic twins with discordant in severity and progression risk of periodontitis. Microbiome analysis indicated that most bacteria were heritable but differed in their abundance and immune response. The dysbiotic bacteria can be considered as risk markers for periodontitis progression.

Dual-Function Semaphorin 4D Released by Platelets: Suppression of Osteoblastogenesis and Promotion of Osteoclastogenesis.

Effects of the antiosteoblastogenesis factor Semaphorin 4D (Sema4D), expressed by thrombin-activated platelets (TPs), on osteoblastogenesis, as well as osteoclastogenesis, were investigated in vitro. Intact platelets released both Sema4D and IGF-1. However, in response to stimulation with thrombin, platelets upregulated the release of Sema4D, but not IGF-1.

Management of tracheostomy in COVID-19 patients: The Japanese experience.

Objective: Involvement in the tracheostomy procedure for COVID-19 patients can lead to a feeling of fear in medical staff. To address concerns over infection, we gathered and analyzed experiences with tracheostomy in the COVID-19 patient population from all over Japan.

Methods: The data for health-care workers involved in tracheostomies for COVID-19-infected patients were gathered from academic medical centers or their affiliated hospitals from all over Japan.

Synthesis and Properties of a Cyclohexa-2,7-anthrylene Ethynylene Derivative.

The synthesis of a cyclohexa-2,7-(4,5-diaryl)anthrylene ethynylene (1) was achieved for the first time by using 1,8-diaryl-3,6-diborylanthracene and 1,8-diaryl-3,6-diiodoanthracene as key synthetic intermediates. Macrocycle 1 possesses a planar conformation of approximately D symmetry, because of the triple-bond linker between the anthracene units at the 2,7-positions. It was confirmed that macrocycle 1, bearing bulky substituents at the outer peripheral positions, behaves as a monomeric form in solution without π-stacking self-association.

Evaluation of the simulator with automatic irrigation control system designed for countermeasures of internal contamination in dental unit water lines.

Unlabelled: The prevention of nosocomial infections is an imperative task. The dental chair unit (DCU) is an indispensable device used in dental treatment. However, it is known that the dental unit water line (DUWL) can become contaminated with biofilm, consisting mainly of heterotrophic bacteria (HB).

Laryngeal suspension, combined with rehabilitation and nutritional support, improved the clinical course of a patient with sarcopenic dysphasia.

Introduction: Sarcopenic dysphasia is a relatively new disease concept describing impairments in swallowing resulting from a generalized loss of skeletal muscle mass.

Presentation Of Case: In this case report, we describe the clinical history and presentation of a 76-year-old man who developed mild sarcopenic dysphasia following a period of physical inactivity after spinal stenosis surgery, which resulted in a loss of 10 kg of body weight in the 10-month period after surgery. The patient's dysphasia was managed with laryngeal suspension, performed via a minimally invasive thyromandibulopexy, in combination with rehabilitation and nutritional support.

Effectiveness and safety of low-concentrated ozonized water for the reduction of contamination in dental unit water lines.

Unlabelled: Contamination of dental unit waterlines (DUWL) with heterotrophic bacteria can cause problems in immune compromised patients (aged, tumor and organ transplantation-patients). We focused on the use of low-concentrated ozonized water (OZW) as the biofilm formation restraint system for DUWL. Here, we examined the effects of low-concentrated OZW on the growth of bacteria and related biofilm formation and harmfulness to dental unit components (DUCs) .

Acceleration of bone regeneration of horizontal bone defect in rats using collagen-binding basic fibroblast growth factor combined with collagen scaffolds.

Background: Basic fibroblast growth factor (bFGF) has been applied for periodontal regeneration. However, the application depends on bone defect morphology because bFGF diffuses rapidly from defect sites. In a previous study, collagen-binding bFGF (CB-bFGF) has been shown to enhance bone formation by collagen-anchoring in the orthopedic field.

Ultrasound-Guided Fine-Needle Aspiration in the Neck Region Using an Optical See-Through Head-Mounted Display: A Randomized Controlled Trial.

Objectives: The purpose of this study was to examine the feasibility of an optical see-through head-mounted display (OST-HMD) to improve ergonomics during ultrasound-guided fine-needle aspiration (FNA) in the neck region.

Methods: This randomized controlled study compared an OST-HMD with a normal ultrasound monitor during an ultrasound-guided FNA in the neck region. Patients with a neck tumor were recruited and randomized into one of two groups.

Polymorphisms in the UGT1A1 gene predict adverse effects of irinotecan in the treatment of gynecologic cancer in Japanese patients.

Irinotecan is a key chemotherapeutic drug used to treat many tumors, including cervical and ovarian cancers; however, irinotecan can cause toxicity, particularly in the presence of uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) gene polymorphisms, which are associated with reduced enzyme activity. Here, we investigated the prevalence of three different variants of UGT1A1 (UGT1A1*6, UGT1A1*27 and UGT1A1*28) and their relationships with irinotecan-induced adverse events in patients with gynecologic cancer, who are treated with lower doses of irinotecan than patients with other types of solid tumors. Fifty-three female patients treated with irinotecan and 362 female patients not treated with irinotecan were screened for UGT1A1*6, UGT1A1*27 and UGT1A1*28.

MicroRNA-196a is a putative diagnostic biomarker and therapeutic target for laryngeal cancer.

Background: MicroRNA (miRNA) is an emerging subclass of small non-coding RNAs that regulates gene expression and has a pivotal role for many physiological processes including cancer development. Recent reports revealed the role of miRNAs as ideal biomarkers and therapeutic targets due to their tissue- or disease-specific nature. Head and neck cancer (HNC) is a major cause of cancer-related mortality and morbidity, and laryngeal cancer has the highest incidence in it.

[CHEP with the total removal of the arytenoid on the tumor-bearing side].

A supracricoid laryngectomy with cricohyoidoepiglottopexy (CHEP) consists of the resection of the whole thyroid cartilage and paraglottic space, while preserving the cricoid cartilage, the hyoid bone, most of the epiglottis and the arytenoids. Laryngeal reconstruction is achieved be suturing the cricoid cartilage and the hyoid bone. This procedure is mainly indicated for large T2 glottic carcinomas and provides a complete resection and laryngeal preservation without requiring a permanent tracheostomy.
