Monomorphic epitheliotropic intestinal T-cell lymphoma(MEITL)is very rare and aggressive subtype of lymphoma with poor prognosis. A 60-year-old man complaining of abdominal pain was underwent partial resection of the jejunum for panperitonitis with a small intestinal perforation. The histopathological and immunohistochemical findings led to the diagnosis of MEITL.

Methods: A total of 1,884 patients ≥ 65 years old who visited the Center for Comprehensive Care on Memory Disorders at Kyorin University Hospital from January 2017 to December 2021 were included in the study.
In current clinical practice, when a fall occurs in a long-term care facility, it is often treated as an accident. Falls are classified as one of the most commonly prevalent geriatric syndromes. As their causes are extremely diverse and complex, their occurrence rate depends on individual susceptibility, even if appropriate fall prevention measures are taken.

However, the underlying mechanism by which COPD affects skeletal muscles remains to be elucidated. Therefore, we investigated the association between oxidative stress and structural alterations in muscles in elastase-induced emphysema mouse models.

We also stopped accepting new patients to our outpatient memory loss clinic. We examined whether or not there was any change in the patients who visited our clinic after the state of emergency was lifted.

In this study, we aimed to identify the incidence and determinants of cognitive impairment in hypertensive patients aged 65 years and above who visited our outpatient clinic and were not previously diagnosed with cognitive impairment. Among 312 patients with hypertension, we found that 35% (n = 109) and 7.

Although the syndromes are very common in older people, it is difficult to treat those by modern medicine due to their complexity. To mitigate the intractable geriatric symptoms, we review the efficacy of aromatherapy, especially for dysphagia, dyspnea, cognitive dysfunction and falls in geriatric syndrome.

The molecular chaperones - CDC37, HSP90α and HSP90β play key roles in cancer progression including epithelial-mesenchymal transition (EMT), although their contribution to EVs-mediated cell-cell communication in tumour microenvironment has not been thoroughly examined. Here we show that triple depletion of the chaperone trio attenuates numerous cancer malignancy events exerted through EV release.

In particular, older persons tend to suffer more severely when infected with a novel coronavirus (SARS-CoV-2) and have higher case mortality rates; additionally, outbreaks frequently occur in hospitals and long-term care facilities where most of the residents are older persons. Unfortunately, it has been stated that the COVID-19 pandemic has caused a medical collapse in some countries, resulting in the depletion of medical resources, such as ventilators, and triage based on chronological age.

Background: Baloxavir marboxil (baloxavir) is a new anti-influenza virus agent that is comparable to oseltamivir phosphate (oseltamivir). Since the efficacy of baloxavir in preventing household transmission of influenza is not well established, we compared the secondary household influenza virus transmission rates between patients on baloxavir vs oseltamivir.
Methods: Between October 2018 and March 2019, we enrolled index patients (diagnosed with influenza and treated with baloxavir or oseltamivir) and household members.

Aim: The Quick Sequential Organ Failure Assessment, and confusion, urea, respiratory rate, blood pressure and age (CURB-65) scores have been used as prognostic factors of mortality related to healthcare-associated pneumonia. However, aspiration pneumonia remains unclear.
Methods: A cross-sectional, prospective cohort study was carried out with 130 inpatients aged ≥75 years at a Geriatric ward of Kyorin University Hospital, Japan.
Matrix metalloproteinase 3 (MMP3) plays multiple roles in extracellular proteolysis as well as intracellular transcription, prompting a new definition of moonlighting metalloproteinase (MMP), according to a definition of protein moonlighting (or gene sharing), a phenomenon by which a protein can perform more than one function. Indeed, connective tissue growth factor (CTGF, aka cellular communication network factor 2 (CCN2)) is transcriptionally induced as well as cleaved by MMP3. Moreover, several members of the MMP family have been found within tumor-derived extracellular vesicles (EVs).

Lewy body disease is associated with decreased cough reflex sensitivity and central respiratory chemosensitivity. Additionally, the insula, associated with the UTC, shows decreased activation and atrophy in dementia with Lewy bodies (DLB).

The properties of three-dimensional (3D) tumor-like organoids (tumoroids) more closely resemble in vivo tumors compared to two-dimensionally cultured cells and are therefore effectively used for assays and drug screening. We here established a repurposed drug for novel anticancer research and therapeutics using a 3D tumoroid-based screening system.

Methods: A retrospective observational multicenter study was carried out to investigate factors related to ADR in older inpatients from geriatric wards of five university hospitals in Japan. Data including drugs profile and short-form comprehensive geriatric assessment were obtained from medical charts.
Background: According to the Clinical Practice Guidelines for , oral vancomycin is to be used in vancomycin tapered and pulsed regimen (VCM-TP) for recurrent infection (CDI). However, data on the efficacy of VCM-TP in Japanese patients with recurrent CDI are scarce. To address this gap, we investigated the efficacy of VCM-TP and performed a case-controlled study to assess the risk factors associated with treatment failure in these patients.
