Risk heterogeneity of bullous pemphigoid among dipeptidyl peptidase-4 inhibitors: A population-based cohort study using Japanese Latter-Stage Elderly Healthcare Database.

Aims/introduction: Although the association between dipeptidyl peptidase-4 (DPP-4) inhibitors and bullous pemphigoid (BP) has begun to be established, some studies have suggested there are risk differences among DPP-4 inhibitors. We conducted a population-based cohort study to examine the risk differences.

Materials And Methods: Using the claims databases of the Fukuoka Prefecture Wide-Area Association of Latter-Stage Elderly Healthcare between April 1, 2013 and March 31, 2017, we conducted a retrospective cohort study to compare patients receiving one DPP-4 inhibitor with those who were prescribed another antidiabetic drug.

Effect of body mass index on vertebral and hip fractures in older people and differences according to sex: a retrospective Japanese cohort study.

Objectives: The purpose of this study was to investigate the incidence of vertebral and hip fractures in the older people and to clarify the relationship between these fractures and body mass index (BMI) along with the impact of sex differences.This was a retrospective cohort study.We used administrative claims data between April 2010 and March 2018.

Influence of Occupational Background on Smoking Prevalence as a Health Inequality Among Employees of Medium- and Small-Sized Companies in Japan.

Tobacco smoking is a major public health problem. In addition, the influence of socioeconomic status on health inequalities has received great attention worldwide. The authors used insurance data of beneficiaries employed in medium- and small-sized Japanese companies to investigate the influence of occupational background on smoking prevalence as a health inequality among workers in Japan.

Risk of depressive disorders after tobacco smoking cessation: a retrospective cohort study in Fukuoka, Japan.

Objective: We sought to examine the effect of smoking cessation on subsequent development of depressive disorders.

Design: This was a retrospective cohort study.

Methods: We used administrative claim and health check data from fiscal years 2010 to 2014, obtained from the largest health insurance association in Fukuoka, Japan.

Efficacy of S-1 monotherapy for older patients with unresectable pancreatic cancer: A retrospective cohort study.

Objectives: Pancreatic cancer is a fatal malignancy that frequently occurs in older patients. However, limited evidence is available on the effects of chemotherapy on older patients with unresectable pancreatic cancer. Here we explored the efficacy of S-1, an oral fluorouracil drug, compared with gemcitabine, as first-line chemotherapy.

Secondhand Smoke and Streptococcal Infection in Young Children Under Japan's Voluntary Tobacco-Free Policy.

Tobacco-free policy in Japan lags behind those of most developed countries. Evidence is required to promote strong implementation of existing policies. This study aimed to assess whether exposure to secondhand smoke (SHS) influences the incidence of streptococcal infection in young children, to further support the need for effective tobacco-free policies in Japan.

Transcatheter Embolization of High-flow Renal Arteriovenous Fistula Using N-butyl Cyanoacrylate Accompanied by Delayed Hydronephrosis.

Renal arteriovenous fistula (AVF) is an uncommon anomaly characterized by the communication between renal arteries and veins. Renal AVFs are often asymptomatic but are occasionally accompanied by hematuria or heart failure. Transcatheter closure with embolization is a safe and effective treatment for renal AVF.

Investigation into the causes of indwelling urethral catheter implementation and its effects on clinical outcomes and health care resources among dementia patients with pneumonia: A retrospective cohort study.

There is a possibility that unnecessary treatments and low-quality medical care, such as inappropriate indwelling urethral catheter use, are being provided to older Japanese individuals.The aim of this study was to investigate contextual effects relating to indwelling urethral catheters in older people with dementia and to clarify the effects of indwelling urethral catheter use on patients' mortality, length of stay (LOS), and health care spending. This retrospective cohort study involved 4501 male and female Japanese participants.

Investigation of the Existence of Supplier-Induced Demand in use of Gastrostomy Among Older Adults: A Retrospective Cohort Study.

The aim of this study is to clarify whether there is small area variation in the use of gastrostomy that is explained by hospital physician density, so as to detect the existence of supplier-induced demand (SID).The study design is a retrospective cohort using claim data of Fukuoka Late Elders' Health Insurance, submitted from 2010 to 2013. Study participants included 51,785 older adults who had been diagnosed with eating difficulties.

A case of isolated adrenocorticotropic hormone deficiency: a rare but possible cause of hypercalcemia.

A 52-year-old woman presented with an 8-month history of epigastric pain, nausea, and weight loss. One year before, she was diagnosed with breast cancer. During the postoperative chemotherapy, she developed epigastric pain and nausea.

A Case of IgG4-Related Hypophysitis Presented with Hypopituitarism and Diabetes Insipidus.

Immunoglobulin (Ig) G4-related systemic syndrome is a recently described entity characterized by elevated serum IgG4 and tissue infiltration of IgG4-positive plasma cells. Pituitary gland can be involved as hypophysitis. We report a case of a 72-year-old man, who presented with general fatigue and weakness.

Case of cytomegalovirus colitis in an immunocompetent patient: a rare cause of abdominal pain and diarrhea in the elderly.

Cytomegalovirus (CMV) colitis usually occurs in immunocompromised patients after undergoing organ transplantation or chemotherapy. We report the case of a 60-year-old immunocompetent Japanese woman who presented with abdominal pain and bloody diarrhea. She was initially diagnosed as having ischemic colitis with pseudomembranous colitis on the basis of her symptoms, Clostridium difficile antigen positivity, and colonoscopic findings, which showed ulcer formation from the sigmoid colon to rectum.

The mobility of Bach2 nuclear foci is regulated by SUMO-1 modification.

The small ubiquitin-like modifier-1 (SUMO-1) modulates the functions of nuclear proteins by changing their structure and/or subnuclear localization. Several nuclear proteins form dynamic higher order nuclear structures, termed non-chromatin nuclear domains, which are involved in the regulation of nuclear function. However, the role that SUMO modification of the component proteins plays in the regulation of the activity and function of nuclear domains is unclear.
