Driveline infections (DLI) remain a major source of morbidity for patients requiring long-term ventricular assist device (VAD) support. We aimed to assess whether VAD driveline exit site (DLES) (abdomen versus chest wall) is associated with DLI. All adult patients who underwent insertion of a Heartware HVAD® or Heartmate II (HMII) between 2009 and 2016 were included. DLI was defined as clinical evidence of DLI accompanied by a positive bacterial swab and need for antibiotics. Competing risks analysis was used to assess the association between patient characteristics and DLI...

BACKGROUND: Several single nucleotide polymorphisms (SNPs) have been implicated in the predisposition to chronic kidney disease (CKD). Atherosclerotic disease is deeply involved in the incidence of CKD; however, whether SNPs related to arteriosclerosis are involved in CKD remains unclear. This study aimed to identify SNPs associated with CKD and to examine whether risk allele accumulation is associated with CKD. METHODS: We conducted a cross-sectional study using data of 4814 male workers to examine the association between estimated glomerular filtration rate (eGFR) and 59 candidate polymorphisms (17 CKD, 42 atherosclerotic diseases)...

As powder agglomeration during storage causes a decrease in the performance of dry powder inhalers (DPIs), it is important to understand the properties of powder agglomeration in developing DPIs. Generally, powder agglomeration is caused by capillary force and crystalline transformation in conditions of higher humidity. It is, however, difficult to correlate crystalline transformation and powder agglomeration, especially when the crystalline transformation is limited. In this study, we focused on the application of inverse gas chromatography (iGC) to detect powder agglomeration directly...

BACKGROUND: To propose an ultrasound-based parameter for the diagnosis of muscle mass loss (MML) in cirrhosis. METHODS: This is an IRB-approved cross-sectional study (October 2013 to January 2017) with written informed consent including 357 subjects-234 cirrhosis and 123 controls. MML was diagnosed using the skeletal muscle index at the L3 level (L3-SMI) on computed tomography (CT). Transcutaneous ultrasound was used to demonstrate a cross section of the right iliopsoas muscle, and the iliopsoas muscle index (IP index) was defined by the iliopsoas muscle area/height(2) (mm(2)/m(2))...

This retrospective study aimed to assess the diagnostic performance of contrast-enhanced ultrasound with Sonazoid (S-CEUS) for liver metastasis. We enrolled in this study 98 patients with 148 histologically proven liver lesions, with 121 metastases and 27 non-metastases. The S-CEUS technique showed sensitivity in 95.0% (115 of 121), specificity in 44.4% (12 of 27) and accuracy in 85.8% (127 of 148) for the diagnosis of metastasis. Higher body mass index had a negative influence on the positive predictive value and accuracy, and a greater depth of the lesion had a negative influence on the accuracy...

AIMS/INTRODUCTION: No reports have been published on the association between dietary intake habits and nocturia in the diabetes population. We therefore estimate this issue among Japanese patients with diabetes mellitus. MATERIALS AND METHODS: Study subjects in the present study were 785 Japanese patients with type 2 diabetes mellitus. Self-administrated questionnaires were used to assess each type of dietary intake habits. Vegetable intake habit was assessed by the following question: Do you have vegetables or seaweed every day?" We used the following two outcomes: 1) nocturia: ≥ 2 voids per night and 2) severe nocturia: ≥ 3 voids per night...

BACKGROUND: Renal anemia is an important complication in non-dialysis chronic kidney disease (CKD) patients as well as in dialysis patients. Although recombinant human erythropoietin has dramatically improved prognosis and quality of life in these patients, there have been issues among non-dialysis CKD patients who exhibit hyporesponsiveness to erythropoiesis-stimulating agent (ESA). The causes and definition of ESA hyporesponsiveness, as well as the incidence of renal and cardiovascular disease (CVD) events in such patients, are yet to be clarified...

AIM: Nocturia is common among patients with type 2 diabetes mellitus, but limited evidence regarding the association between body mass index (BMI) and nocturia exists among such patients. The aim of the present study, therefore, was to evaluate the association between BMI and nocturia among Japanese patients with type 2 diabetes mellitus. METHODS: Study participants were 809 Japanese patients with type 2 diabetes mellitus. Study participants were considered to have nocturia if they answered "two or more" to the question: "How many times do you typically wake up to urinate from sleeping at night until waking in the morning?" We used the following two outcomes: (i) moderate nocturia was defined as ≥2 voids per night; and (ii) severe nocturia was defined as ≥3 voids per night...

AIM: Because subclinical hypothyroidism (thyroid-stimulating hormone [TSH] > 4.5 IU/mL) is associated with adverse pregnancy outcome, including early pregnancy loss, TSH is recommended to be titrated to ≤2.5 mIU/L in levothyroxine-treated women before pregnancy. The purpose of this study was to determine whether borderline-subclinical hypothyroidism (borderline-SCH; 2.5 < TSH ≤ 4.5 IU/mL) affects the outcome of subsequent pregnancies in women with unexplained recurrent pregnancy loss (uRPL)...

We hypothesized that meteorological conditions on the onset day and conditions on the former days may play important roles in the modulation of physical conditions. Associations of meteorological factors and their changes in former days with stroke onset are of interest. We conducted a multicenter retrospective study to evaluate the frequency of stroke events and their interaction with meteorological conditions and their daily changes. Acute stroke patients (n = 3935, 73.5±12.4 years, 1610 females) who were admitted to 7 stroke hospitals in three restricted areas were enrolled in this study...

The diagnostic criteria of osteoporosis were established based on bone mineral density (BMD). Therefore, BMD measured by dual energy X-ray absorptiometry has been recognized as the gold standard to diagnose osteoporosis. However, discrepancies between fracture risk and BMD have been recognized. Bone is composed of collagen scaffold reinforced by hydroxyapatite. Both protein scaffold and hydroxyapatite are involved in bone quality. BMD may indicate bone mineralization but potentially fail to assess the protein scaffold...

Prostate cancer, one of the most common malignant tumors among men, is closely associated with obesity and, thus far, several studies have suggested the association between obesity and aggressive pathological characteristics in the United States. However, the effect of obesity on prostate cancer mortality is controversial, and it remains unclear whether obesity contributes to the aggressiveness of prostate cancer in Asian patients. The aim of the present study was to investigate the association between body mass index (BMI) and the clinicopathological characteristics of prostate cancer in 2,003 Japanese patients who underwent radical prostatectomy...

Because of the relative simplicity of its nervous system, Caenorhabditis elegans is a useful model organism to study learning and memory at cellular and molecular levels. For appetitive conditioning in C. elegans, food has exclusively been used as an unconditioned stimulus (US). It may be difficult to analyze neuronal circuits for associative memory since food is a multimodal combination of olfactory, gustatory, and mechanical stimuli. Here, we report classical appetitive conditioning and associative memory in C...
