Aim: The purposes of the present study were to investigate risk factors for incident disability in activities of daily living (ADL) among middle-aged and older women, and to determine whether there are differences in risk factors according to age groups.

Methods: The participants were 264 Japanese women aged 40 years and older. A self-administered questionnaire was used to survey participants about difficulty in carrying out selected basic and instrumental ADL at baseline and at follow up.

A long survivor with local relapse of hilar cholangiocarcinoma after R1 surgery treated with chemoradiotherapy: a case report and literature review.

The treatment outcome of extrahepatic cholangiocarcinoma remains insufficient because it is difficult to obtain accurate diagnosis of tumor spreading and effective treatment agent is quite limited in spite of substantial current efforts, all of which have been unsuccessful except for gemcitabine plus cisplatin. The patient was a 60-year-old female who had developed hilar cholangiocarcinoma and underwent extrahepatic bile duct resection. Although it was conceivable that it would be the R1 resection, the patient wanted to receive limited resection to avoid postoperative complication mainly because she was depressed.

Residual total pancreatectomy: Short- and long-term outcomes.

Background/objectives: Because of limited numbers of patients, there are limited data available regarding outcomes after residual total pancreatectomy (R-TP). This study aimed to assess outcomes after the R-TP vs the one-stage total pancreatectomy (O-TP), especially focused on the pancreatic adenocarcinoma cases.

Methods: From 2005 to 2014, all patients who underwent the R-TP (n = 8) and the O-TP (n = 12) for pancreatic primary malignancy were prospectively enrolled.

Sex differences in the serum level of endogenous ligands for estrogen receptor β in the elderly population.

Animal studies suggest that estrogen receptor β (ERβ)-agonists, but not ERα-agonists, are antidepressants. Several endogenous ligands for ERβ have been proposed, including 5α-androstane-3β, 17β-diol (3βAdiol), Androstenediol (Δ5-diol), and 7α-hydroxydehydroepiandrosterone (7α-OH-DHEA). The aim of this study was to determine the serum and salivary levels of natural ERβ ligands in men and women with and without past depressive episodes in the elderly population.

Methods: Patients with early-stage RA (n = 76) were enrolled and underwent 1.5-T MRI of both wrists and finger joints.

Usefulness of chair stand time as a surrogate of gait speed in diagnosing sarcopenia.

Aim: Determining gait speed as a measure of physical performance is recommended in diagnosing sarcopenia. Gait speed measurements require a certain amount of space (e.g.

Diverse Basis of β-Catenin Activation in Human Hepatocellular Carcinoma: Implications in Biology and Prognosis.

Aim: β-catenin signaling is a major oncogenic pathway in hepatocellular carcinoma (HCC). Since β-catenin phosphorylation by glycogen synthase kinase 3β (GSK3β) and casein kinase 1ε (CK1ε) results in its degradation, mutations affecting these phosphorylation sites cause β-catenin stabilization. However, the relevance of missense mutations in non-phosphorylation sites in exon 3 remains unclear.

The diagnostic role of the neutrophil-to-lymphocyte ratio in predicting pancreatic ductal adenocarcinoma in patients with pancreatic diseases.

Background: Accurately diagnosing pancreatic ductal adenocarcinomas (PDACs) is challenging because of the loss of vascularity and poor imaging. The neutrophil-to-lymphocyte ratio (NLR) has been reported to predict poor prognosis in several types of malignancy including PDAC; however, the diagnostic role of NLR in PDAC has never been addressed.

Methods: This study retrospectively assessed 297 patients who underwent curative pancreatic resection for pancreatic tumors from 1995-2015, including 140 with PDACs, 58 with pancreatic neuroendocrine tumors (PNETs), 76 with intraductal papillary mucinous neoplasms (IPMNs), 13 with mucinous/serous cyst neoplasms, 7 with solid pseudopapillary neoplasms, and 3 with tumor-forming pancreatitis.

Heterogeneity of KRAS Mutations in Pancreatic Ductal Adenocarcinoma.

Objectives: Activating Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations are the most common and frequent changes observed in pancreatic cancer. This study aimed to determine the frequency and extent of intratumoral and metastatic lymph node KRAS mutation heterogeneity of resected pancreatic ductal adenocarcinoma.

Methods: Tumor tissues macrodissected from tumor centers, invasion fronts (n = 97), and lymph nodes (n = 11) were subjected to DNA extraction and mutation analysis of KRAS codons 12 and 13 by pyrosequencing.

Acute gastric volvulus is a torsion of the stomach by more than 180° and a life-threatening condition. We present a 50-year-old male patient with acute abdominal pain who has Down syndrome/trisomy 21. Computed tomography showed a significant distended stomach with features of a severe gastric volvulus.

KRAS, BRAF, and PIK3CA mutations, and patient prognosis in 126 pancreatic cancers: pyrosequencing technology and literature review.

The oncogenic hallmarks of pancreatic cancer (PC), such as the KRAS, BRAF, and PIK3CA mutations, have been widely investigated. However, almost all of the previous studies were limited by small sample sizes. In addition, previous data on the KRAS mutation and clinical outcomes in PC remain inconclusive.

Improvement of Pharmaceutical Properties of Isoprenoid Compounds through the Formation of Cyclodextrin Pseudorotaxane-Like Supramolecules.

The purpose of this study was to design cyclodextrin (CyD)-based pseudorotaxane-like supramolecular complexes with various isoprenoid compounds, such as reduced coenzyme Q10 (R-CoQ10), squalene, tocotrienol, and teprenone, and to evaluate their pharmaceutical properties. Squalene, tocotrienol, and teprenone formed precipitates with β-CyD and γ-CyD in aqueous solution, whereas R-CoQ10 formed precipitates with γ-CyD aqueous solution. The results of powder X-ray diffraction and (1)H-NMR analyses indicated that these precipitates are derived from pseudorotaxane-like supramolecular complexes.

Hemoglobin as a possible biochemical index of hypertension-induced vascular damage.

Background: We previously reported on the positive association of hemoglobin with hypertension and atherosclerosis. On the other hand, hepatocyte growth factor (HGF) has been evaluated as a possible biochemical index of hypertension-induced vascular damage. However, no studies have reported on a correlation between hemoglobin and HGF accounting for hypertension status.

Predictors of clinical outcomes in patients with neuropsychiatric systemic lupus erythematosus.

Introduction: Neuropsychiatric systemic lupus erythematosus (NPSLE), a serious organ disorder with a variety of symptoms, has diverse therapeutic outcomes because of the variability of NPSLE manifestations. A comprehensive association study of NPSLE among clinical and immunopathogenic aspects and outcomes has not been conducted.

Methods: We analyzed the laboratory data, NPSLE symptoms, and clinical outcomes at 1yr post-treatment and the profiles of 27 cytokines, chemokines and growth factors in cerebrospinal fluid (CSF) samples using the Bio-Plex Human 27-plex panel from 28 NPSLE patients.

Fibroblasts prolong serum prostate-specific antigen decline after androgen deprivation therapy in prostate cancer.

In patients with prostate cancer (PCa), serum prostate-specific antigen (PSA) is a useful marker for evaluating the effects of androgen deprivation therapy (ADT). Intuitively, most urologists expect that a more rapid PSA decline in response to ADT would be positively associated with extended survival. Recently, we have reported that prolonged gradual serum PSA decline after ADT is strongly associated with favorable prognosis in PCa patients, however, the mechanism remains unknown.

Biochemical classification of tauopathies by immunoblot, protein sequence and mass spectrometric analyses of sarkosyl-insoluble and trypsin-resistant tau.

Intracellular filamentous tau pathology is the defining feature of tauopathies, which form a subset of neurodegenerative diseases. We have analyzed pathological tau in Alzheimer's disease, and in frontotemporal lobar degeneration associated with tauopathy to include cases with Pick bodies, corticobasal degeneration, progressive supranuclear palsy, and ones due to intronic mutations in MAPT. We found that the C-terminal band pattern of the pathological tau species is distinct for each disease.

The Neutrophil-to-Lymphocyte Ratio Predicts Malignant Potential in Intraductal Papillary Mucinous Neoplasms.

Background: Accurately identifying malignant components in patients with pancreatic intraductal papillary mucinous neoplasms (IPMN) remains challenging. Preoperative neutrophil-to-lymphocyte ratio (NLR) is a marker of poor prognosis in patients with several types of malignancy. This study assessed whether NLR was predictive of intraductal papillary mucinous carcinoma (IPMC) in patients with IPMN.
