PURPOSE: Age and comorbidities increase the surgical risk for patients with acute cholecystitis and impact on the initial treatment selection. The aim of this article is the implementation of objective risk criteria that may be used to select the most appropriate treatment. METHODS: We carried out a prospective cohort study of all patients who were admitted to the hospital with a diagnosis of acute cholecystitis during 2014. They were initially allocated to three different treatment groups according to cholecystitis grade, number of days from clinical onset, and surgical risk scores as follows: immediate surgery by sepsis (EmergS), early surgery (EarlyS), or medical treatment group (MedT)...

During the 25th annual meeting of the Asia-Pacific Association for the Study of the Liver (APASL 2016) in Tokyo, we organized and moderated an inaugural satellite symposium on the autoimmune liver diseases, autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC). Following the keynote lecture by John M. Vierling (USA), speakers from the Asia-Pacific region provided an up-to-date perspective on the epidemiology, clinical practice and research in AIH and PBC in the Asia-Pacific region. Although epidemiology and clinical features of AIH seem to be similar in East Asia compared to those in western countries, the majority of patients with AIH are detected at an advanced stage and have higher mortality rates in South Asia, indicating an unmet need for earlier diagnosis and the initiation of appropriate immunosuppressive treatment...

Importance: Acute cholangitis (AC), particularly severe AC, has historically required urgent endoscopic decompression, although the timing of decompression is controversial. We previously identified 2 admission risk factors for adverse outcomes in AC: total bilirubin level greater than 10 mg/dL and white blood cell count greater than 20 000 cells/µL. Objectives: To validate previously identified prognostic factors in AC, evaluate the effect of timing of endoscopic retrograde cholangiopancreatography on clinical outcomes, and compare recent experience with AC vs an historical cohort...

BACKGROUND AND STUDY AIMS: Gallstone impaction at the ampulla of Vater is a critical condition, and the standard treatment is endoscopic papillotomy. However, the clinical features remain largely unclear, and some patients are reluctant to undergo papillotomy because of a bleeding tendency. The aim of this study was to clarify the clinical features of gallstone impaction at the ampulla of Vater and to examine the effectiveness of endoscopic biliary drainage without papillotomy. PATIENTS AND METHODS: We retrospectively examined 30 patients who had undergone endoscopic treatment for gallstone impaction at the ampulla of Vater between 2010 and 2015...

BACKGROUND: Each year, 1-4 % of people with known gallstones become symptomatic, either presenting with biliary colic or as acute cholecystitis. The distinction between both diagnoses remains challenging. To aid the proper diagnosis, the revised 2013 Tokyo Guidelines (TG 2013) were proposed with a self-acclaimed diagnostic accuracy of over 90 %. However, this accuracy has not been verified by others so far. OBJECTIVE: To determine the accuracy of the TG 2013 guidelines in the diagnosis of acute cholecystitis both in its single components of fever, inflammatory markers and US features and of the combined application of the TG 2013 guidelines as a whole...

Adaptive servo-ventilation support and Waon therapy are recently developed non-pharmacological and noninvasive therapies for patients with heart failure refractory to guideline-directed medical therapy. These therapies decrease both preload and afterload, increase cardiac output, and appear to ameliorate autonomic nerve activity. However, the time course of autonomic nerve activity during these therapies remains unclear. We performed heart rate variability analysis using the MemCalc power spectral density method (MemCalc system; Suwa Trust Co, Tokyo) to assess autonomic nerve activity during adaptive servo-ventilation support and Waon therapy in two different cases and determined the time course of autonomic nerve activity during these therapies...

BACKGROUND: Rilpivirine is listed as a recommended or alternative key drug in the current ART guidelines. E138K in HIV-1 reverse transcriptase (RT) is a primary mutation in resistance to rilpivirine, although in vitro experiments showed it confers only <3-fold resistance. An unidentified mechanism could amplify resistance to rilpivirine conferred by E138K. OBJECTIVES: The objective of this study was to reveal the mechanism amplifying rilpivirine resistance conferred by E138K...

Tokyo Guideline 2013 (TG13) is an international guideline for the diagnosis, classification and treatment of acute cholangitis. Progress and controversy for the two years after TG13 was summarized. Endoscopic ultrasound (EUS) and magnetic resonance cholangiopancreatography (MRCP) are both effective imaging tests for common bile duct (CBD) stones. More factors e.g. obesity may be involved in severity assessment. Initiation of broad-spectrum antibiotics addressing the typical Gram-negative enteric bacteria spectrum and early biliary drainage are the mainstay therapeutic options...

Few studies have evaluated the effect of short-term exposure to particulate matter (PM) less than 2.5μm in diameter (PM2.5) or to coarse particles on infant mortality. We evaluated the association between short-term exposure to PM and infant mortality in Japan and assessed whether adverse health effects were observable at PM concentrations below Japanese air quality guidelines. We used a time-stratified, case-crossover design. The participants included 2086 infants who died in the 23 urbanized wards of the Tokyo Metropolitan Government between January 2002 and December 2013...
