The COVID-19 pandemic-induced behavioral restrictions and their impact on child and adolescent psychiatric units-Infection control or freedom.

Aim: This study examines the impact of COVID-19 pandemic-induced behavioral restrictions on child psychiatric inpatients in Japan, particularly focusing on limitations placed on outings and overnight stays as infection-control measures.

Methods: Data were collected from inpatients from the children's mental health registry between January 2016 and December 2022. The clinical data, such as age, gender, diagnosis, result of polymerase chain reaction (PCR) tests, frequency of outings and overnight stays before and after the pandemic, were compared.

[Tumefactive Demyelinating Lesions].

Tumefactive demyelinating lesions (TDL), defined as inflammatory demyelinating lesions, may develop either during treatment for multiple sclerosis and related disorders or as the first demyelinating episode without any past medical history suggesting demyelination. If the latter, it would be so delicate to diagnose as demyelination. Especially in such situations, biopsy is often necessary in addition to neuroimaging for distinction TDL with tumorous or infectious diseases.

Efficacy of Airbo·Wave in Nighttime Compression for Leg Lymphedema.

This study aimed to clarify the efficacy of Airbo·Wave EV1 in nighttime compression therapy as part of complex decongestive therapy (CDT) for leg lymphedema. We retrospectively reviewed 33 patients with leg lymphedema who used Airbo·Wave EV1 between April 2021 and September 2022. In these patients, the changes in leg volume and skin hardness were assessed using a scale ranging from 1 (softest) to 7 (hardest), and dermal thickness before and after the use of Airbo·Wave EV1 was evaluated.

Clinical characteristics of child and adolescent psychiatric outpatients engaging in fireplay or arson: a case-control study.

Background: Fireplay and arson incidents among children and adolescents have gained attention because of their potentially severe consequences and societal impacts. Understanding the underlying psychiatric characteristics of individuals engaging in fireplay or arson is crucial for early identification and targeted intervention. However, there is a lack of research conducted in clinical psychiatric populations in this context.

Differential Metabolic Stability of 4α,25- and 4β,25-Dihydroxyvitamin D and Identification of Their Metabolites.

Vitamin D () is metabolized by various cytochrome P450 (CYP) enzymes, resulting in the formation of diverse metabolites. Among them, 4α,25-dihydroxyvitamin D () and 4β,25-dihydroxyvitamin D () are both produced from 25-hydroxyvitamin D () by CYP3A4. However, is detectable in serum, whereas is not.

Randomized controlled trial comparing cosmetic results of midline incision versus off-midline incision for specimen extraction in laparoscopic colectomy.

Purpose: A notable advantage of laparoscopic colorectal surgery is that only a small incision at the extraction site is necessary, which is considered to be cosmetically beneficial. Meanwhile, the optimal extraction site for the resected specimen in laparoscopic colectomy is controversial in terms of cosmetic benefit. This randomized controlled trial compares midline and off-midline extraction sites in laparoscopic colectomy in patients with colon cancer, with consideration of cosmetic benefits as the primary endpoint.

Androgen promotes squamous differentiation of atypical cells in cervical intraepithelial neoplasia via an ELF3-dependent pathway.

Background: Since the human papillomavirus vaccines do not eliminate preexisting infections, nonsurgical alternative approaches to cervical intraepithelial neoplasia (CIN) have been required. We previously reported that FOXP4 (forkhead box transcription factor P4) promoted proliferation and inhibited squamous differentiation of CIN1-derived W12 cells. Since it was reported that FOXP expressions were regulated by the androgen/androgen receptor (AR) complex and AR was expressed on the CIN lesions, in this study we examined the effects of androgen on CIN progression.

The Circadian Clock, Nutritional Signals and Reproduction: A Close Relationship.

The circadian rhythm, which is necessary for reproduction, is controlled by clock genes. In the mouse uterus, the oscillation of the circadian clock gene has been observed. The transcription of the core clock gene period () and cryptochrome () is activated by the heterodimer of the transcription factor circadian locomotor output cycles kaput () and brain and muscle Arnt-like protein-1 ().

Kinetics of Anti-SARS-CoV-2 Antibody Response Following Two Doses of the BNT162b2 mRNA Vaccine: A Japanese Single-Center Primary Care Clinic Report Involving Volunteers and Patients with Autoimmune Disease.

Despite the promising effectiveness of the coronavirus disease 2019 vaccination using an mRNA vaccine, the short efficacy duration and some poor responses to the vaccination remain major concerns. We aimed to clarify the monthly kinetics of the anti-SARS-CoV-2 spike receptor-binding domain antibody response after two doses of the BNT162b2 vaccine in a Japanese population. A chemiluminescent enzyme immunoassay (CLIA) and an enzyme-linked immunosorbent assay were used to measure the antibody levels in 81 Japanese adults (age, <65 years).

A rare case of Pseudomonas aeruginosa enteritis induced by pembrolizumab.

A 72-year-old male had pseudomonal enteritis related to pembrolizumab. Chemotherapy for hypopharyngeal carcinoma with lung metastasis comprised cisplatin, 5-FU, and pembrolizumab. On day 14 of chemotherapy treatment he had a sudden prominent abdominal bulge, decreased consciousness, and drop in blood pressure in septic shock.

Evaluating the daily life of child and adolescent psychiatric outpatients during temporary school closure over COVID-19 pandemic: A single-center case-control study in Japan.

This study evaluated the clinical characteristics of mental health of child and adolescent psychiatric patients during temporary school closure throughout the coronavirus 2019 (COVID-19) pandemic in Japan using the Questionnaire - Children with Difficulties (QCD) and other useful psychological rating scales. The participants were those who visited the Department of Child and Adolescent Psychiatry, Kohnodai Hospital. From those 1,463 participants, case and control groups were selected: 92 patients who visited the hospital during the temporary school closure from March 2020 to May 2020 (case group) and randomly sampled sex- and age-matched 92 patients during the pre-COVID period from April 2017 to March 2020 (control group).

FOXP4 inhibits squamous differentiation of atypical cells in cervical intraepithelial neoplasia via an ELF3-dependent pathway.

Although the human papillomavirus (HPV) vaccine is effective for preventing cervical cancers, this vaccine does not eliminate pre-existing infections, and alternative strategies have been warranted. Here, we report that FOXP4 is a new target molecule for differentiation therapy of cervical intraepithelial neoplasia (CIN). An immunohistochemical study showed that FOXP4 was expressed in columnar epithelial, reserve, and immature squamous cells, but not in mature squamous cells of the normal uterine cervix.

High visceral to subcutaneous fat area ratio predicts early postoperative small bowel obstruction after surgery for colorectal cancer.

Purpose: Risks for postoperative small bowel obstruction have been demonstrated in several reports, most of which indicated male sex was a risk factor, but with the reason remaining unknown. We tested the hypothesis that it could be because males have more visceral fat than females. This prospective observational study aims to examine risks of early postoperative small bowel obstruction (EPSBO) after colorectal cancer surgery and the association between visceral to subcutaneous fat area ratio (V/S ratio) and EPSBO.

What is related to postoperative outcome of frail status in elective colorectal cancer surgery?

Background: The population affected by colorectal cancer is growing, and there is an increasing need for prevention of functional decline following treatment. We proposed that the Kihon Checklist published by the Japanese Ministry of Health, Labor, and Welfare would be an appropriate means of frailty assessment for prediction of postoperative complications in older patients with colorectal cancer. This prospective cohort study aims to identify the factors influencing postoperative frailty.

Synthesis of Deuterium-Labeled Vitamin D Metabolites as Internal Standards for LC-MS Analysis.

Blood levels of the vitamin D (D) metabolites 25-hydroxyvitamin D (25(OH)D), 24,25-dihydroxyvitamin D, and 1α,25-dihydroxyvitamin D (1,25(OH)D) are recognized indicators for the diagnosis of bone metabolism-related diseases, D deficiency-related diseases, and hypercalcemia, and are generally measured by liquid-chromatography tandem mass spectrometry (LC-MS/MS) using an isotope dilution method. However, other D metabolites, such as 20-hydroxyvitamin D and lactone D, also show interesting biological activities and stable isotope-labeled derivatives are required for LC-MS/MS analysis of their concentrations in serum. Here, we describe a versatile synthesis of deuterium-labeled D metabolites using A-ring synthons containing three deuterium atoms.

Prognostic value of CD155/TIGIT expression in patients with colorectal cancer.

Introduction: The interaction of CD155 with its ligand, the T cell immunoreceptor with Ig and ITIM domains (TIGIT), is being studied owing to its potential to act as a target in the treatment of various solid tumors. However, the relationship between CD155 and TIGIT in colorectal cancer (CRC) prognosis is not known. We hypothesized that the TIGIT-CD155 pathway suppresses the attack of T cells on tumors, thereby affecting CRC prognosis.
