Despite available pharmacological and interventional therapies, refractory angina is a common and disabling clinical condition, and a major public health problem, which affects patients' quality-of-life, and has a significant impact upon health care resources. Persistent angina is common not only in patients who are not good candidates for revascularization, but also in patients following successful revascularization. Clearly, there is a need for additional treatment options for refractory angina beyond currently available pharmacological and interventional therapies...

Primary biliary cholangitis (PBC) is an immune-mediated liver disease characterized by chronic inflammation of the intrahepatic bile ducts, causing progressive ductopenia, cholestasis and fibrosis, and leading to liver failure. Ursodeoxycholic acid (UDCA) is the first-line therapy for the treatment of PBC patients. This is effective in majority of patients; however, up to 20 percent of patients have an incomplete response to UDCA therapy and have a reduced prognosis as compared to healthy individuals. Obeticholic acid (OCA) has been recently registered as second-line therapy for patients with incomplete response to UDCA, with plans to demonstrate the long-term clinical efficacy...

Cryptosporidium parvum has been suggested as a suitable target for in vitro efficacy testing of disinfectants. To improve validity of a method based on exposure of HCT-8 monolayers to C. parvum oocysts we here critically evaluate and we propose certain procedural steps needed for the validation of disinfectants. Within a range of 0.02% to 0.4%, sodium taurocholate at 0.2% stimulated infection most efficiently while preserving host cell integrity. The course of invasion was monitored for periods of 30-240min post infection (p...

BACKGROUND: Patients with acute coronary syndromes (ACS) and a history of atrial fibrillation (AF) have indications for both dual antiplatelet therapy (DAPT) and oral anticoagulation (OAC). Triple therapy (TT), the combination of DAPT and OAC, is recommended in guidelines. We examined studies comparing clinical outcomes on DAPT versus TT for patients with AF and ACS. METHODS: We searched Medline, Medline pending, EMBASE and Evidence-Based Medicine Reviews databases for studies published between January 2000 to December 2016 in AF patients with ACS that compared DAPT and TT that reported ischaemic and/or bleeding outcomes...

Overhydration is a frequent complication in dialysis patients. It has been linked with hypertension, left ventricular hypertrophy, arterial stiffness, atherosclerosis uremic cardiomyopathy, and all-cause mortality or cardiovascular morbidity. In addition, predialysis underhydration is also associated with increased risk of death in ESRD patients. In this context, the optimal evaluation of hydration status is a must. However, this mission is not easy or accurate. In the last 10 years, several new methods have been tested in dialysis patients, particularly bioimpedance and lung ultrasonography...

BACKGROUND: A decision-to-delivery interval (DDI) of no more than 20 minutes has long been considered a requirement for cesarean sections, even though there have hardly been any studies on this topic. We retrospectively investigated data relevant to DDI for emergency cesarean sections performed for the most common indications, namely, suspected and documented fetal asphyxia. METHODS: We analyzed data on emergency in-hospital cesarean sections in the period 2008-2015...

Traditionally, the main indication for cardiopulmonary exercise testing (CPET) in heart failure (HF) was for the selection of candidates to heart transplantation: CPET was mainly performed in middle-aged male patients with HF and reduced left ventricular ejection fraction. Today, CPET is used in broader patients' populations, including women, elderly, patients with co-morbidities, those with preserved ejection fraction, or left ventricular assistance device recipients, i.e. individuals with different responses to incremental exercise and markedly different prognosis...

INTRODUCTION: Glycerol phenylbutyrate (GPB) is approved in the US for the management of patients 2months of age and older with urea cycle disorders (UCDs) that cannot be managed with protein restriction and/or amino acid supplementation alone. Limited data exist on the use of nitrogen conjugation agents in very young patients. METHODS: Seventeen patients (15 previously on other nitrogen scavengers) with all types of UCDs aged 2months to 2years were switched to, or started, GPB...

OBJECTIVE: This review covers the pharmacokinetics and pharmacodynamic of β-blockers, the rationale for their use, some recent controversies in its use for managing hypertension, as well as, the beneficial properties of the third-generation β-blockers beyond hypertension. BACKGROUND: The efficacy and safety of -blockers in the treatment of hypertension and other cardiovascular diseases have been established during more than 50 years of clinical experience. Recent updates of clinical guidelines have downgraded the use of -blockers for the treatment of uncomplicated hypertension to second and third line therapy...

Heart failure (HF) is one of the leading causes of morbidity, mortality, and health care expenditures in the US and worldwide. For three decades, the pillars of treatment of HF with reduced ejection fraction (HFrEF) were medications that targeted the sympathetic nervous system (SNS) and the renin-angiotensin-aldosterone system (RAAS). Prior attempts to augment the natriuretic peptide system (NPS) for the management of HF failed either due to lack of significant clinical benefit or due to the unacceptable side effect profile...

BACKGROUND: Renin-angiotensin system (RAS) signaling and angiotensin-converting enzyme 2 (ACE2) have been implicated in the pathogenesis of acute respiratory distress syndrome (ARDS). We postulated that repleting ACE2 using GSK2586881, a recombinant form of human angiotensin-converting enzyme 2 (rhACE2), could attenuate acute lung injury. METHODS: We conducted a two-part phase II trial comprising an open-label intrapatient dose escalation and a randomized, double-blind, placebo-controlled phase in ten intensive care units in North America...

BACKGROUND: The Combination Therapy of Hypertension to Prevent Cardiovascular Events (COPE) trial was conducted to compare the effects of regimens combining the dihydropyridine calcium-channel blocker benidipine with each of 3 secondary agent types (an angiotensin-receptor blocker (ARB), a β-blocker and a thiazide) in Japanese hypertensive outpatients who did not achieve target blood pressure (<140/90 mmHg) with benidipine 4 mg/day alone. The analysis included 3,293 patients (ARB, 1,110; β-blocker, 1,089; thiazide, 1,094) with a median follow-up of 3...

BACKGROUND: ADI-PEG 20 is a pegylated form of the arginine-depleting enzyme arginine deiminase. Normal cells synthesize arginine with the enzyme argininosuccinate synthetase (ASS1); ADI-PEG 20 selectively targets malignant cells, which lack ASS1. METHODS: A single-arm, nonrandomized, open-label, phase 1/1B, standard 3 + 3 dose escalation with an expansion cohort of 9 patients at the recommended phase 2 dose (RP2D) was conducted. Patients who had metastatic pancreatic cancer, up to 1 line of prior treatment (the dose-escalation cohort) or no prior treatment (the expansion cohort), and an Eastern Cooperative Oncology Group performance status of 0 to 1 were included...

INTRODUCTION: Psychosocial factors are increasingly recognised as important determinants of cardiovascular disease risk. The North Texas Heart Study aims to understand the mechanisms responsible for this association with a focus on social vigilance (ie, scanning the environment for social threats). There is also growing interest in supplementing traditional methods (eg, survey assessment of psychosocial risk paired with cross-sectional and longitudinal health outcomes) with daily or repeated momentary assessment of psychosocial factors...

Naoki Misumida, Akihiro Kobayashi, Sun Moon Kim, Ahmed Abdel-Latif, Khaled M Ziada
BACKGROUND: Prior studies have shown that routine follow-up coronary angiography (CAG) following percutaneous coronary intervention (PCI) increases the incidence of revascularization without a clear reduction in major adverse clinical events. However, none of these prior studies were adequately powered to evaluate hard clinical endpoints such as myocardial infarction (MI) or death and thus the clinical utility of such practice remains to be determined.Methods and Results:We conducted a systematic review and meta-analysis of randomized trials that compared clinical outcomes after PCI between patients who underwent routine follow-up CAG and those who only had clinical follow-up...

BACKGROUND/OBJECTIVES: Little is known about relation of overall breakfast quality with cardiometabolic risk factors. Therefore, this study aimed to explore sex-specific associations between breakfast quality and cardiometabolic risk profiles in a sample of an upper middle-aged German population. SUBJECTS/METHODS: Cardiometabolic profiles of 339 men and 329 women were cross-sectionally assessed using an overall biomarker score (BScore), glycated hemoglobin (HbA1c), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), blood pressure, body mass index (BMI) and waist circumference (WC)...

REVIEW
Gerhard Rogler, Martin Hausmann
The concepts on the pathophysiology of intestinal fibrosis in Crohn's disease (CD) have changed in recent years. Some years ago fibrosis was regarded to be a consequence of long-standing inflammation with subsequent destruction of the gut wall matrix followed by scar formation and collagen deposition. Fibrosis in CD patients appeared to be an irreversible process that could hardly be influenced. Therefore, the main target in CD therapy was to control inflammation to avoid fibrosis development. Many of these assumptions seem to be only partially true...

Robert Kemp, Vinay Prasad
BACKGROUND: Surrogate outcomes are not intrinsically beneficial to patients, but are designed to be easier and faster to measure than clinically meaningful outcomes. The use of surrogates as an endpoint in clinical trials and basis for regulatory approval is common, and frequently exceeds the guidance given by regulatory bodies. DISCUSSION: In this article, we demonstrate that the use of surrogates in oncology is widespread and increasing. At the same time, the strength of association between the surrogates used and clinically meaningful outcomes is often unknown or weak...
