With an increasing number of large-scale population-based cardiac magnetic resonance (CMR) imaging studies being conducted nowadays, there comes the mammoth task of image annotation and image analysis. Such population-based studies would greatly benefit from automated pipelines, with an efficient CMR image analysis workflow. The purpose of this work is to investigate the feasibility of using a fully-automatic pipeline to segment the left ventricular endocardium and epicardium simultaneously on two orthogonal (vertical and horizontal) long-axis cardiac cine MRI scans...

AIMS: The use of continuous subcutaneous insulin infusion (CSII) in type 1 diabetes (T1D) has increased in recent years. Sensor-augmented pump therapy (SAP) with low glucose suspend (LGS) (allowing temporary suspension of insulin delivery if blood glucose level falls below a pre-defined threshold level) provides additional benefits over CSII alone, but is associated with higher acquisition costs. Therefore, a cost-effectiveness analysis of SAP+LGS versus CSII in patients with T1D was performed...

Marlène Goubault, Rebecca Burlaud
Lekking males aggregate to attract females and contribute solely to egg fertilization, without any further parental care. Evolutionary theory therefore predicts them to be non-choosy towards their mates, because any lost mating opportunities would outweigh the benefits associated with such preferences. Nevertheless, due to time costs, the production of energetically costly sexual displays, and potential sperm limitation, the mating effort of lekking males is often considerable. These factors, combined with the fact that many females of varying quality are likely to visit leks, could favor the evolution of male mate preferences...

The UK has adopted a broader approach to the introduction of Environmental Quality Standard (EQS) for the aquatic environment than many other jurisdictions around the world, with a greater focus on the implementation of scientifically derived standards. This follows the publication of a report by the Royal Commission on Environmental Pollution in 1998 which drew attention to the need to recognise that whilst an EQS is often just viewed as a numerical value, it also has other important characteristics that need to be recognised if it is to be a practical and effective regulatory tool...

Benjamin D Robertson, Siddarth Vadakkeveedu, Gregory S Sawicki
We present a novel biorobotic framework comprised of a biological muscle-tendon unit (MTU) mechanically coupled to a feedback controlled robotic environment simulation that mimics in vivo inertial/gravitational loading and mechanical assistance from a parallel elastic exoskeleton. Using this system, we applied select combinations of biological muscle activation (modulated with rate-coded direct neural stimulation) and parallel elastic assistance (applied via closed-loop mechanical environment simulation) hypothesized to mimic human behavior based on previously published modeling studies...

Insulin has been used as a standard treatment for patients with diabetes for almost 100 years. Over time, advances in insulin development have improved its pharmacologic properties. (Online access: http://courses.elseviercme.com/t2dm/666). Most recently, the US Food and Drug Administration approved a novel, follow-on basal insulin agent, with more expected to be commercially available in the near future. With the imminent availability of follow-on basal insulin agents, clinicians need to be aware of the potential benefits and concerns in order to facilitate informed decision making and to provide the best possible advice and guidance to their patients with diabetes...

BACKGROUND AND AIMS: Precision, personalized or stratified medicine, which promises to deliver the right treatment to the right patient, is a topic of international interest in both the lay press and the scientific literature. A key aspect of precision medicine is the identification of biomarkers that predict the response to medications (i.e. pharmacogenetics). We examined why, despite the great strides that have been made in biomarker identification in many areas of medicine, only in oncology has there been substantial progress in their clinical implementation...

INTRODUCTION: The introduction of total mesorectal excision (TME) in the 1980s was pivotal in the surgical treatment for rectal carcinoma (RC). Routinely applied TME led to a significant reduction in the incidence of local recurrences. The purpose of our paper is to present the results of our non-randomized study comparing prospectively acquired data from radical resection / rectal extirpation using classic open access, laparoscopy and da Vinci robotic system. METHOD: The study group included 116 patients with RC who underwent radical surgical treatment between 1/2014-12/2016, after which the collected resection specimens were assessed in pathology laboratories of the referring hospital using the Quirkes protocol...

BACKGROUND AND OBJECTIVES: Perioperative nutritional support has become a hot topic in the clinical management of congenital heart disease (CHD). Postoperative enteral nutrition (EN) offers many benefits, such as protection of the intestinal mucosa, reduced risk of infection, and low clinical costs. Interruptions in EN frequently influence nutritional support and clinical outcomes. We, therefore, aimed to determine the causes of interruptions in postoperative EN in CHD patients and discuss clinical counter measures...

Grahame J Elder, Jacqueline Center
Rising levels of serum phosphate occur late in the course of chronic kidney disease (CKD) and have been easy targets for nephrologists to treat using phosphate binding drugs, as well as fertile ground for the pharmaceutical industry, for meta-analysis and for the earnest pontifications of guideline writers. Unfortunately, the evidence does little to support this focus, which might be better applied to earlier, adaptive hormonal changes, and to phosphate balance rather than serum phosphate levels. Nevertheless, phosphate binders are ubiquitously prescribed to patients on dialysis, and often prescribed to patients with earlier stages of CKD; for which there is no evidence of benefit and some evidence that calcium-based binders (CBBs) and possibly non-CBBs may cause more harm than placebo...

Quantifying the energy balance is essential for testing socio-ecological models. To reveal costs and benefits of group living in Japanese macaques from the perspective of feeding competition, Kurihara and Hanya (Am J Primatol 77:986-1000, 2015) previously compared feeding behavior between two different-sized groups of macaques (larger group 30-35 individuals; smaller group 13-15 individuals) in the coastal forest of Yakushima, Japan. The results suggested that the larger group exhibited greater feeding effort because of intragroup scramble competition and that the smaller group suffered from higher travel costs, possibly owing to intergroup contest competition...

Hyunwook Kim, Dong-Ryeol Ryu
The number of patients with end-stage renal disease (ESRD) has rapidly increased, as has the cost of dialysis. Peritoneal dialysis (PD) is an established treatment for ESRD patients worldwide; it has a variety of advantages, including autonomy and flexibility, as well as economic benefits in many countries compared to hemodialysis (HD). However, the long-term survival rate of PD remains poor. Although direct comparison of survival rate between the dialysis modalities by randomized controlled trials is difficult due to the ethical issues, it has always been a crucial point when deciding which dialysis modality should be recommended to patients...

Statins are lipid-lowering medications used for primary and secondary prevention of atherosclerotic disease and represent a substantial portion of drug costs in the United States. A better understanding of prescribing patterns and drug costs should lead to more rational utilization and help constrain health care expenditures in the United States. The 2013 Medicare Provider Utilization and Payment Data: Part D Prescriber Public Use File for the State of Hawai'i was analyzed. The number of prescriptions for statins, total annual cost, and daily cost were calculated by prescriber specialty and drug...

BACKGROUND: Despite clear evidence that antibiotics do not cure viral infections, the problem of unnecessary prescribing of antibiotics in ambulatory care persists, and in some cases, prescribing patterns have increased. The overuse of antibiotics for treating viral infections has created numerous economic and clinical consequences including increased medical costs due to unnecessary hospitalizations, antibiotic resistance, disruption of gut bacteria, and obesity. Recent research has underscored the importance of collaborative patient-provider communication as a means to reduce the high rates of unnecessary prescriptions for antibiotics...

BACKGROUND: Decompressive craniectomy is performed to relieve intracranial pressure as an emergency procedure. There is no large study to systematically evaluate the benefit of decompressive craniectomy versus best medical therapy. This study evaluates the survival and long-term functional outcomes of decompressive craniectomy for spontaneous intracranial hemorrhage. METHODS: A total of 54 eligible patients with spontaneous supratentorial hemorrhage (median age 55, IQR 47-64) who underwent decompressive craniectomy were retrospectively matched to 72 patients managed with best medical treatment (median age 58, IQR 32-74)...

BACKGROUND: Bystander cardiopulmonary resuscitation (CPR) is associated with a greater likelihood of survival to hospital discharge after out-of-hospital cardiac arrest (OHCA). However the long-term survival benefits in relationship to cost have not been well-studied. We evaluated bystander CPR, hospital-based costs, and long-term survival following OHCA in order to assess the potential cost-effectiveness of bystander CPR. PATIENTS AND METHODS: We conducted a retrospective cohort study of consecutive EMS-treated OHCA patients >=12years who arrested prior to EMS arrival and outside a nursing facility between 2001 and 2010 in greater King County, WA...
