Given Japan's super-ageing society and its need for developing community-based integrated care system, the role of home care nursing is becoming increasingly important. A central concern in home care nursing is regional/spatial placement of home nursing stations and accessibility for patients. Analysis based on geographic information systems (GIS) may be useful in home care nursing research. We conducted a literature review of home care nursing research based on GIS in Japan. A total of 4 articles were selected following a search of medical literature databases...

Bacterial pneumonia is one of the most important infectious diseases in terms of incidence, effect on quality of life, mortality, and impact on society. Pneumonia was the third leading cause of death in Japan in 2011. In 2016, 119 650 Japanese people died of pneumonia, 96% of whom were aged 65 years and above. The symptoms of pneumonia in elderly people are often atypical. Aspiration pneumonia is seen more frequently than in young people because of swallowing dysfunction in the elderly. The mortality rate is also higher in the elderly than in young people...

Intraventricular hemorrhage (IVH) is a devastating morbidity in preterm infants and can result in poor neurodevelopmental outcomes. Intraventricular hemorrhage usually occurs within 72 hours after birth; post-acute-phase IVH (>1 week after birth) is uncommon. Development of the hemostatic system in fetuses and neonates is an age-dependent evolving process, and the neonatal hemostatic system is characterized by low levels of vitamin K-dependent factors, with further reduction caused by prematurity. Importantly, a severe coagulation deficiency can be a major contributing factor of IVH...

PURPOSE: Oral care in hospitalized patients with psychiatric disorders is important. However, some patients with psychiatric disorders cannot undergo oral care because of psychiatric symptoms and cognitive decline. The effect of a standardized oral hygiene intervention on the prevention of pneumonia in hospitalized patients with psychiatric disorders was investigated. METHOD: Patients were divided into 2 groups: control group (N = 259), patients without standardized intervention who were enrolled on April 2014 as the time point of baseline, and intervention group (N = 263), patients with standardized intervention who were enrolled on April 2015 as the time point of baseline...

Increased global mortality is associated with atherosclerosis, which appears to be independent of race. Cardiovascular disease is one of the leading causes of mortality and morbidity in Japan. Atherosclerosis, an inflammatory disease characterized by abnormal lipid accumulation and inflammation in the arterial wall, is the main underlying cause of cardiovascular disease. Numerous cardiovascular risk scores have been developed and are used to prioritize patients' treatment needs. The predictive performance of risk scores established in Western nations needs to be examined in Japanese populations...

The patient was a 66-year-old woman, G2P2. The patient presented a chief complaint of irregular postmenopausal bleeding 1 month ago. A transvaginal ultrasonography showed that bilateral ovaries were not enlarged and uterine endometrium was thickened, measuring at 9 mm. As a result of endometrial curettage, the simple endometrial hyperplasia was revealed. A blood examination showed an elevated estradiol level of 67 pg/mL, an elevated level of testosterone 0.64 ng/mL, and a slightly suppressed follicle-stimulating hormone (FSH) level of 34...

We report an elderly male patient with hyperammonemia induced by intrahepatic portal-systemic shunt without cirrhosis (IPSSwoC). The occasional emergence of his erratic behaviors was misdiagnosed as a psychiatric disorder. Regardless of his uneven symptoms, IPSSwoC was suspected due to his hyperammonemia. The contrast computed tomography of the abdomen revealed a congenital type of IPSSwoC. As blood ammonia levels are inconstant, repeated blood tests are recommended when this disease is suspected in elderly patients with psychiatric symptoms...

BACKGROUND: Because of the potential anti-inflammatory effects, linagliptin, a therapeutic dipeptidyl peptidase-4 inhibitor, is used as an effective drug for diabetic patients for whom inflammation is a prognosis-related factor. We investigated the anti-inflammatory mechanism of linagliptin using seven markers. METHODS: We pretreated human umbilical vein endothelial cells (HUVECs), with linagliptin and lipopolysaccharide (LPS). The cytosolic fractions were evaluated for protein kinase A (PKA), protein kinase B (PKB), protein kinase C (PKC), ratio of reactive oxygen species (ROS) and Cu/Zn superoxide dismutase (SOD), activator protein 1 (AP-1), and adenosine 3',5'-cyclic monophosphate (cAMP)...

A case of late-infantile Krabbe disease in a patient who presented with developmental regression and spastic quadriplegia in late infancy is reported. Brain magnetic resonance imaging (MRI) at 11 months of age showed predominant corticospinal tract involvement, which usually appears in adult Krabbe disease. Galactocerebrosidase activity in lymphocytes and skin fibroblasts was very low. Genetic testing revealed compound heterozygous mutations of the galactocerebrosidase (GALC) gene, c.635_646 delinsCTC and c...

We examined the prevalence of specific perinatal complications of monochorionic-diamniotic twin pregnancies in cases without any abnormal findings until the second trimester of pregnancy. This was a retrospective cohort study performed at a tertiary perinatal center in Tokyo, Japan. There were 88 cases of uncomplicated monochorionic-diamniotic twin pregnancies at 28 weeks of gestation. In five of them (5.7%), there were serious complications associated with placental circulatory imbalance between the twins during the third trimester of pregnancy...

Familial dysalbuminemic hyperthyroxinemia (FDH) is a familial autosomal dominant disease caused by mutation in the albumin gene that produces a condition of euthyroid hyperthyroxinemia. In patients with FDH, serum-free thyroxine (FT4) and free triiodothyronine (FT3) concentrations as measured by several commercial methods are often falsely increased with normal thyrotropin (TSH). Therefore, several diagnostic steps are needed to differentiate TSH-secreting tumor or generalized resistance to thyroid hormone from FDH...

Abnormal glucose tolerance during pregnancy is associated with perinatal complications. We used continuous glucose monitoring (CGM) in pregnant women with glucose intolerance to achieve better glycemic control and to evaluate the maternal glucose fluctuations. We also used CGM in women without glucose intolerance (the control cases). Furthermore, the standard deviation (SD) and mean amplitude of glycemic excursions (MAGE) were calculated for each case. For the control cases, the glucose levels were tightly controlled within a very narrow range; however, the SD and MAGE values in pregnant women with glucose intolerance were relativity high, suggesting postprandial hyperglycemia...

OBJECTIVE: Heart rate variability (HRV) has been reported to be an independent predictor of all-cause and sudden cardiac death in patients with heart failure. In the aging heart, however, both autonomic and cardiac functions appear to be altered. We assessed the relationship between aging and responsiveness of HRV and ventricular remodeling to beta-adrenergic blockade therapy in patients with heart failure and reduced ejection fraction (HFREF). METHODS: Twenty-eight clinically stable patients with chronic heart failure, sinus rhythm, and left ventricular ejection fraction <50% as confirmed by echocardiography were included...
