Dental Care to Reduce Aspiration Pneumonia Recurrence: A Prospective Cohort Study.

Background: Aspiration pneumonia has a high recurrence rate, and oral care by dentists has been found effective in preventing its onset; however, this has not been evaluated using prospective studies. Therefore, we conducted a prospective study to evaluate the effectiveness of professional oral care by dentists in reducing aspiration pneumonia recurrence in older adult patients.

Methods: In this prospective cohort study, we evaluated a dental oral care intervention, using a historical control group (control group).

Associations of disease duration and anti-citrullinated peptide antibody status with the effectiveness of abatacept in biologic-naïve patients with rheumatoid arthritis: Post hoc analysis of a multicentre, real-world observational study in Japan (ORIGAMI).

Objectives: The aim of the article is to investigate the associations of disease duration and anti-cyclic citrullinated peptide antibody (ACPA) status with the effectiveness of abatacept in biologic-naïve patients with rheumatoid arthritis (RA).

Methods: We performed post hoc analyses of the Orencia® Registry in Geographically Assembled Multicenter Investigation (ORIGAMI) study of biologic-naïve RA patients aged ≥20 years with moderate disease activity who were prescribed abatacept. Changes in the Simplified Disease Activity Index (SDAI) and Japanese Health Assessment Questionnaire (J-HAQ) at 4, 24, and 52 weeks of treatment were analysed in patients divided according to ACPA serostatus (positive/negative), disease duration (<1/≥1 year), or both.

Dietary Intake in Older Patients with Dementia Prior to and After the Onset of Coronavirus Disease 2019.

This was an observational study of hospitalized patients with dementia who developed COVID-19. The disease course, dietary intake, and disease severity (mild/severe) were evaluated. Twenty-nine patients with a median age of 84 years, with both mild (18) and severe conditions, (11) were evaluated.

Polymyalgia Rheumatica in a Patient with Pseudogout and Dementia.

BACKGROUND The differential diagnosis of generalized pain includes reactivity associated with bacterial and viral infections, autoimmune rheumatic disease, and orthopedic diseases. Obtaining a detailed medical history and establishing an accurate diagnosis are difficult in elderly patients with dementia. In addition, the differential diagnosis between polymyalgia rheumatica and pseudogout is often difficult.

Delayed treatment of bacteremia during the COVID-19 pandemic.

Objectives: Coronavirus disease (COVID-19) blindness, that is, the excessive consideration of the disease in diagnosis, has reportedly led to delayed diagnosis of some diseases. We compared several clinical measures between patients admitted for bacteremia during the two months of the COVID-19 pandemic and those admitted during the same period in 2019. We hypothesized that the pandemic has led to delayed treatment of bacteremia.

Plasma Exchange Therapy to Reduce Mortality in Japanese Patients With Diffuse Alveolar Hemorrhage and Microscopic Polyangiitis.

Diffuse alveolar hemorrhage (DAH) is well known as a serious complication of microscopic polyangiitis (MPA). We examined the effectiveness of plasma exchange (PLEX) therapy to reduce mortality in Japanese DAH patients with MPA. This retrospective, double-center, observational cohort study included 20 DAH patients with MPA who were admitted to Juntendo University Hospital or Juntendo Koto Geriatric Medical Center between April 1998 and March 2018.

Predictive factors for mortality in elderly Japanese patients with severe microscopic polyangiitis: A retrospective single-center study.

Purpose: To determine mortality and its predictive factors in elderly Japanese patients with severe microscopic polyangiitis (MPA).

Method: This retrospective single-center study determined the mortality of 52 patients with MPA who were admitted to our geriatric medical center from 2002 to 2014. The variables at baseline, including patient demographics, clinical characteristics, and treatment, were analyzed for their association with mortality.

[A clinical analysis of elderly dementia patients with physical comorbidities].

Aim: To investigate the current status of elderly dementia patients with physical illnesses and identify optimal care strategies for this growing population.

Methods: This retrospective study included elderly dementia patients who (i) received in-patient treatment for a physical comorbidity at the dementia ward of the Juntendo Tokyo Koto Geriatric Medical Center, and (ii) who were discharged from April 2009 to March 2011.

Results: The study population was 390 patients (144 males, 246 females), with a mean [±SD] age of 80.

[Blood culture results in elderly febrile patients].

Aim: We retrospectively evaluated blood culture results in elderly patients (≥65 years) with a fever due to infection.

Methods: We examined the bacteria isolated from blood cultures and compared them to bacteria detected in infected lesions that caused bacteremia. We compared the types of bacteria isolated in the two groups (the community-acquired group and the hospital-acquired group).

[A case of intravascular large B-cell lymphoma with rapidly progressive cognitive impairment after cerebral infarction].

A 67-year-old man started to show symptoms of dementia and developed convulsions accompanied by presyncope. Since an old cerebral infarction was found, he was given a diagnosis of symptomatic epilepsy, treated with antiepileptics. Dementia progressed rapidly, resulting in admission to a dementia ward.

[Death in geriatric pneumonia patients].

Aim: Pneumonia-associated deaths are the 4th leading cause of death in elderly people, and fatality tends to increase with age, especially after the age of 65. We aimed to further define convalescence in this patient population by examining the clinical characteristics of elderly pneumonia patients.

Methods: We retrospectively examined the data of 292 patients aged 65 years or older who had died of pneumonia.

Investigation of pathological and clinical features of lupus nephritis in 73 autopsied cases with systemic lupus erythematosus.

The aims of this study were to analyze the clinical and pathological features of lupus nephritis (LN) and examine the association between these features and pathological condition, treatment, and prognosis. Of the 177 systemic lupus erythematosus patients who died while receiving inpatient care at Juntendo University Hospital between 1960 and 2001, we investigated the clinical features, treatment, and pathological features of 73 of these who underwent pathological autopsy and had a clear medical history. We divided these cases into two groups, i.

A case of very-late-onset systemic lupus erythematosus.

A 93-year-old woman was admitted to our hospital because of fever. Radiographic findings revealed accumulation of pleural fluid. Moreover, blood tests revealed inflammation, lymphopenia, hypocomplementemia, positive for anti-nuclear antibody, and elevated anti-DNA antibody level.

Immunoadsorption plasmapheresis using a phenylalanine column as an effective treatment for lupus nephritis.

Immunoadsorption plasmapheresis (IAPP) is effective for eliminating pathogenic molecules such as anti-DNA antibody (anti-DNA Ab) and immune complexes from the serum of patients with systemic autoimmune diseases. The purpose of this study was to assess patients with lupus nephritis (LN) treated by IAPP using a phenylalanine column and determine its efficacy with respect to conventional therapies. Six patients (M = 1, F = 5) with histologically proven LN associated with proteinuria and abnormal sedimentation on urinalysis were the subjects for this study.

CD154 expression and mRNA stability of activated CD4-positive T cells in patients with systemic lupus erythematosus.

Abstract The expression of CD154 (CD40 ligand) on activated CD4+ T cells is known to be transient and tightly regulated for antigen-specific immune responses, and is increased and prolonged among patients with systemic lupus erythematosus (SLE). We investigated the regulation of CD154 expression by determining the protein and mRNA expression with PMA and ionomycin stimulation in CD4+ T cells, and confirmed their increase and prolongation in SLE T cells. Treatment with actinomycin D, a transcription inhibitor, after PMA and ionomycin stimulation was performed, and the findings revealed that the stability of CD154 mRNA increased significantly in activated SLE T cells compared with that of controls.

Plasma adsorption in critical care.

Plasmapheresis therapies such as plasma exchange (PE), double filtration plasmapheresis (DFPP), or immunoadsorption plasmapheresis (IAPP) have become therapeutic tools in critical care. PE or DFPP are limited by their non- or semiselective removal of all plasma components. Replacement fluids such as fresh frozen plasma and albumin are necessary during PE or DFPP.
