Cochlear Implants (CIs) are medical implantable devices that can restore the sense of hearing in people with profound hearing loss. Clinical trials assessing speech intelligibility in CI users have found large intersubject variability. One possibility to explain the variability is the individual differences in the interface created between electrodes of the CI and the auditory nerve. In order to understand the variability, models of the voltage distribution of the electrically stimulated cochlea may be useful...

E Olgiati, C Russell, D Soto, P Malhotra
Spatial neglect (SN) is an extremely common disorder of attention; it is most frequently a consequence of stroke, especially to the right cerebral hemisphere. The current view of SN is that it is not a unitary deficit but a multicomponent syndrome. Crucially, it has been repeatedly shown that it has a considerable negative impact on rehabilitation outcome. Although a number of behavioral and pharmacological therapies have been developed, none of these appears to be applicable to all patients with SN or has proved unequivocally successful in clinical trials...

Long-term clinical outcomes of new-generation drug-eluting stents in complex anatomic and clinical settings are not well defined. This study assessed the impact of patient and lesion complexity on 2-year outcomes after coronary revascularization with ultrathin strut biodegradable-polymer (BP) sirolimus-eluting stents (SES) versus durable-polymer (DP) everolimus-eluting stents (EES). In a prespecified analysis of the BIOSCIENCE randomized trial (NCT01443104), complex patients (911 of 2,119; 43%) were defined by the presence of acute ST-elevation myocardial infarction (MI); left ventricular ejection fraction ≤30%; renal dysfunction; insulin-treated diabetes; treatment of ostial lesion, bypass graft, unprotected left main lesion; or 3-vessel intervention...

Since the updated pulmonary hypertension (PH) guidelines published in 2015, two major landmark trials have provided additional insight regarding therapeutic algorithms of PH. In this review, we concisely summarized the key findings of peer‑reviewed studies published in the last one year in the field of PH. These studies have enhanced our therapeutic abilities by introducing a new potent agent, selexipag, and by demonstrating the advantage of upfront combination therapy (endothelin receptor antagonist and phosphodiesterase‑5 inhibitor) versus single agent therapy in group 1 PH...

REVIEW
Jared Radbel, Daniel Boutsikaris
Recent literature continues to refine which components of the early goal-directed therapy (EGDT) algorithm are necessary. Given it utilizes central venous pressure, continuous central venous oxygen saturation, routine blood transfusions, and inotropic medications, this algorithm can be timely, invasive, costly, and potentially harmful. New trials highlight early recognition, early fluid resuscitation, appropriate antibiotic treatment, source control, and the application of a multidisciplinary evidence-based approach as essential components of current sepsis management...

BACKGROUND AND OBJECTIVES: Ultrasound-guided subsartorial saphenous nerve block is commonly used to provide complete surgical anesthesia of the foot and ankle in combination with a popliteal sciatic nerve block. However, in part owing to its small caliber and absence of a prominent vascular landmark in the subsartorial plane distal to the adductor canal, the saphenous nerve is more difficult to reliably block than the sciatic nerve in the popliteal fossa. Although the saphenous nerve is a sensory nerve only, neurostimulation can be used to elicit a "tapping" sensation on the anteromedial aspect of the lower leg extending toward the medial malleolus...

REVIEW

The landmark trials on cardiac resynchronization therapy (CRT) have focused on patients with sinus rhythm at inclusion. Little data are available on the efficacy of CRT in patients with atrial fibrillation (AF), while AF has a high prevalence (20-40%) among patients receiving CRT. This review focuses on the detrimental effect of AF on CRT response and discusses management of patients with AF during CRT. Uncertainty remains as to which thresholds of AF burden can lead to a reduced response to CRT and every effort should be made in trying to assess and guarantee successful biventricular pacing in patients with AF...

Polycythemia vera (PV), a clonal disorders of hematopoietic stem/progenitor cells that manifests with prevalent expansion of red cell mass, is the most frequent among chronic myeloproliferative neoplasms (MPN). It is characterized by a V617F point mutation in JAK2 exon 14 , or less common mutations in exon 12, in virtually all cases. The landmark discovery of autonomously activated JAK/STAT signaling pathway paved the way for the clinical development of the first target drug, the JAK1 and JAK2 inhibitor ruxolitinib, that is now approved for patients with resistance or intolerance to hydroxyurea...

BACKGROUND: -Despite growing recognition of Type 2 myocardial infarction (T2MI; related to supply-demand mismatch), little is known about its risk factors or its association with outcome. METHODS: -A single center cohort of patients undergoing coronary or peripheral angiography with or without intervention was prospectively enrolled and followed for incident type 1 and T2MI, as well as major adverse cardiovascular events (MACE, a composite of all-cause death, non-fatal MI, heart failure, stroke, transient ischemic attack, peripheral arterial complication and cardiac arrhythmia)...

Immunotherapy using engineered autologous T cells has been attempted for decades, but clinical trials have only recently demonstrated efficacy. The combination of enhanced manufacturing techniques, highly efficient engineering, appropriate target selection and synthetic receptors with potent T cell activating domains has led to the development of highly-active cellular therapy products. B-cell malignancies have served as the paradigmatic diseases to initially evaluate and subsequently hone engineered T cells targeting cancer...

BACKGROUND: We report cardiac events in the Persephone trial which compares 6-12 months of adjuvant trastuzumab in women with confirmed HER2-positive, early-stage breast cancer. METHODS: Clinical cardiac events were defined as any of the following: symptoms and/or signs of congestive heart failure (CHF) and new or altered CHF medication. In addition, left ventricular ejection fraction (LVEF) was measured at baseline and then 3 monthly for 12 months. RESULTS: A total of 2500 patients, aged 22-82, were included: 1251 randomised to 12 months and 1249 to 6 months of trastuzumab treatment...

Cardiovascular (CV) and kidney disease are common and significant complications in people with type 2 diabetes (T2DM). CV disease is the leading cause of death, morbidly and hospitalisations for people with T2DM. Furthermore, diabetic kidney disease is a major risk factor for CV disease and is the main reason why patients need renal replacement therapy. In this perspective, we highlight the results of the recent landmark EMPA-REG OUTCOME trial which has shown that empagliflozin, a member of the sodium-glucose co-transporter 2 (SGLT-2) inhibitor class of glucose lowering medications, reduces death from CV causes, hospitalisation for heart failure and progression to end stage kidney disease in patients with T2DM and established CV disease...

PURPOSE: The question of whether publication of selected clinical trials is temporally followed by changes in prescribing of adjunctive lipid-lowering medications was evaluated. METHODS: In this retrospective preanalysis and postanalysis, Veterans Health Administration (VHA) patients 18 years or older who received a new or renewed order for any lipid-lowering medication between April 2, 2004, and September 2, 2014, were included. This period was chosen based on the publication dates of three trials investigating the efficacy of nonstatin medications: Simvastatin with or without Ezetimibe in Familial Hypercholesterolemia (ENHANCE, April 3, 2008), Effects of Combination Lipid Therapy in Type 2 Diabetes Mellitus (ACCORD Lipid, March 14, 2010), and Niacin in Patients with Low HDL Cholesterol Levels Receiving Intensive Statin Therapy (AIM-HIGH, December 15, 2011)...

STUDY OBJECTIVE: Lumbar puncture is a commonly performed procedure, although previous studies have documented low rates of successful completion in infants. Ultrasonography can visualize the anatomic landmarks for lumbar puncture and has been shown in some studies to reduce the failure rate of lumbar puncture in adults. We seek to determine whether ultrasonography assisted site marking increases success for infant lumbar punctures. METHODS: This was a prospective, randomized, controlled trial in an academic pediatric emergency department (ED)...

Recent studies show differences in individual motion and shoaling tendency between strains of the same species. Here, we analyse collective motion and response to visual stimuli in two morphologically different strains (TL and AB) of zebrafish. For both strains, we observed 10 groups of 5 and 10 zebrafish swimming freely in a large experimental tank with two identical landmarks (cylinders or discs) for 1 h. We tracked the positions of the fish by an automated tracking method and compute several metrics at the group level...

Importance: Pulmonary arterial hypertension (PAH) is characterized by severe remodeling of the distal pulmonary arteries, increased pulmonary vascular resistance, and right ventricular dysfunction that promotes heart failure. Once regarded as largely untreatable, evidence-based decision making now guides clinical management of PAH and improves outcomes. However, misconceptions regarding the approach to PAH in the modern era are common and associated with substandard clinical care. Observations: The clinical profile of PAH has changed substantially since its original description...
