The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait that worsens in darkness and on uneven ground. There are typically no symptoms while sitting or lying under static conditions. A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR). This deficit is diagnosed for the high-frequency range of the angular VOR by a bilaterally pathologic bedside head impulse test (HIT) and for the low-frequency range by a bilaterally reduced or absent caloric response...

This article considers differences between the representation of mutation in science fiction films from the 1950s and the present, and identifies distinctive changes over this time period, both in relation to the narrative causes of genetic disruption and in the aesthetics of its visual display. Discerning an increasingly abject quality to science fiction mutations from the 1970s onwards-as a progressive tendency to view the physically opened body, one that has a seemingly fluid interior-exterior reversal, or one that is almost beyond recognition as humanoid-the article connects a propensity for disgust to the corresponding socio-cultural and political zeitgeist...

BACKGROUND: The ANCA-associated vasculitides (AAV) are systemic autoimmune inflammatory disorders characterised by necrotising inflammation affecting small to medium-sized blood vessels. Despite improvements in survival, infection and cardiovascular disease remain leading causes of morbidity and mortality. Considerable evidence suggests that CD4 + CD28null T-cell expansions, predominantly seen in Cytomegalovirus (CMV) seropositive individuals, are associated with systemic dysregulation of immune function leading to a heightened risk of infection and cardiovascular disease...

OBJECTIVE: Bilateral vestibular loss (BVL) is often diagnosed with great delay and an underlying cause is only identified in 50-80%. We measured horizontal and vertical semicircular canal function using the video-head-impulse test (vHIT) and hypothesized that specific vHIT-patterns may be linked to certain etiologies. METHODS: We retrospectively analyzed 109 BVL-patients linked to aminoglycoside vestibulotoxicity (n=16), Menière's disease (n=10), infectious inner-ear disorders (n=11), sensorineural hearing-loss (n=11), cerebellar-ataxia-neuropathy-vestibular-areflexia-syndrome (CANVAS, n=5), other causes (n=19) as well as those with unknown origin (n=47)...

Worldwide, an estimated 200 million people have chronic kidney disease (CKD), the most common causes of which include hypertension, arteriosclerosis, and diabetes. Importantly, ~40% of patients with diabetes develop CKD, yet evidence from major multicenter randomized controlled trials shows that intensive blood glucose control through pharmacological intervention can reduce the incidence and progression of CKD. Standard therapies for the treatment of type 2 diabetes include metformin, sulfonylureas, meglitinides, thiazolidinediones, and insulin...

Critics consider the 1908-1909 portrait of William Osler by S. Seymour Thomas the best of six oil-on-canvas portraits of Osler done from life, including those by the more acclaimed US artists John Singer Sargent and William Merritt Chase. Osler called it "the best pictorial diagnosis I have ever seen" and told Thomas "I am at your service." A reappraisal of Seymour Thomas explains why his portrait makes us feel much as the artist did in Osler's presence, which is the original English-language definition of "empathy...

OBJECTIVES: Cervical total disc replacement (TDR) is an emerging technology. Cervical arthroplasty theoretically reduces the risk of adjacent level disc degeneration and segmental instability. However, the factors that influence postoperative range of motion (ROM) and clinical outcomes are not fully understood. The aim of our study was to evaluate the effect of intervertebral disc height on the range of motion and clinical outcomes after single-level implantation of Prestige LP cervical disc prosthesis METHODS: A total of 160 patients with single-level Prestige LP cervical disc prosthesis were evaluated...

Recurrence of hepatitis C virus (HCV) after liver transplantation (LT) can rapidly lead to liver graft cirrhosis and, therefore, graft failure and retransplantation or death. The aim of the present study was to assess efficacy and tolerance of sofosbuvir (SOF)-based regimens for the treatment of HCV recurrence in patients with severe fibrosis after LT. The Compassionate Use of Protease Inhibitors in Viral C Liver Transplantation (CULPIT) study is a prospective multicenter cohort including patients with HCV recurrence following LT treated with second generation direct antivirals...

INTRODUCTION: Despite the unquestionable advantages of Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Imaging in visualizing the spatial distribution and the relative abundance of biomolecules directly on-tissue, the yielded data is complex and high dimensional. Therefore, analysis and interpretation of this huge amount of information is mathematically, statistically and computationally challenging. AREAS COVERED: This article reviews some of the challenges in data elaboration with particular emphasis on machine learning techniques employed in clinical applications, and can be useful in general as an entry point for those who want to study the computational aspects...

BACKGROUND: Combination therapy with canagliflozin and insulin was investigated in a prescribed substudy of the canagliflozin Cardiovascular Assessment Study (CANVAS); however, it was not evaluated in Japanese patients with type 2 diabetes mellitus (T2DM). Since the usage profile of insulin therapy and pathologic features of Japanese patients differ from those of Caucasian patients, we determined the clinical benefit of such a combination therapy in Japanese patients. METHODS: Patients who had inadequate glycemic control despite insulin, diet and exercise therapies were randomized into placebo (n = 70) and canagliflozin 100 mg (n = 76) groups that were administered once daily in addition to their prior insulin therapy in this double-blind, placebo-controlled study...

Age related macular degeneration is a disease which occurs in aged individuals. There are various changes that occur at the cellular, molecular and physiological level with advancing age (Samiec et al., 1988; Sharma K. et al., 2014). Drusen deposition between retinal pigment epithelium (RPE) and Bruch's membrane (BM) is one of the key features in AMD patients (Mullins et al., 2000; Hageman et al., 2001) similar to Aβ/tau aggregates in Alzheimer's disease (AD) patients. The primary goal of this review is to discuss whether the various candidate genes and associated biomarkers, that are known to play an independent role in progression of AMD, exert deleterious effect on phenotype, alone or in combination, in Indian AMD patients from the same ethnic group and the significance of such research...

In France, the hepatitis B maternal-fetal transmission prevention strategy is based on serovaccination at birth. Serum therapy is to inject 30IU/kg of anti-HBs specific immunoglobulins of human origin in the first hours of life, which in practice corresponds to 1ml or 100IU. Vaccination should also be performed during the first hours of life, and a new injection should be performed at 1month and 6months. In infants less than 32weeks and/or less than 2kg, lower vaccine response leads to prescribe an additional injection at 2months...

The rabbit corneal micropocket angiogenesis assay uses the avascular cornea as a substrate canvas to study angiogenesis in vivo. Through the use of standardized slow-release pellets, a predictable angiogenic response is generated over the course of 1-2 weeks and then quantified. Uniform slow-release pellets are prepared by mixing purified angiogenic growth factors such as basic fibroblast growth factor or vascular endothelial growth factor and a synthetic polymer to allow slow release. A micropocket is surgically created in the rabbit cornea under anesthesia and a pellet implanted...

Recombinant overexpression of a protein or a protein complex using any specific heterologous host can be an overwhelming challenge. The reasons may range from low yield and poor solubility of a single-subunit enzyme to the wrong stoichiometry or the incomplete assembly of a multiprotein complex. Whatever the reason, overcoming the difficulties will take the researcher into a journey through the seemingly countless options that exist for protein expression. While some choices stand to reason fairly straightforwardly (e...

UNLABELLED: There is an increasing need for rich and dynamic biological data visualizations in bioinformatic web applications. New standards in web technologies, like SVG or Canvas, are now supported by most modern web browsers allowing the blossoming of powerful visualizations in biological data analysis. The exploration of different ways to visualize genomic data is still challenging due to the lack of flexible tools to develop them. Here, I present a set of libraries aimed at creating powerful tree- and track-based visualizations for the web...

MOTIVATION: Versatile and efficient variant calling tools are needed to analyze large scale sequencing datasets. In particular, identification of copy number changes remains a challenging task due to their complexity, susceptibility to sequencing biases, variation in coverage data and dependence on genome-wide sample properties, such as tumor polyploidy or polyclonality in cancer samples. RESULTS: We have developed a new tool, Canvas, for identification of copy number changes from diverse sequencing experiments including whole-genome matched tumor-normal and single-sample normal re-sequencing, as well as whole-exome matched and unmatched tumor-normal studies...

We evaluated the cost-effectiveness and the budget impact of new DAA-based regimen use in France. A Markov model simulated chronic hepatitis C (CHC) treatment interventions with IFN-based and IFN-free regimens at stage of fibrosis ≥F3, ≥F2 or regardless of fibrosis stage, and treatment either with the least or the most expensive combination. It estimated quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs). It also assessed the budget impact over 5 years of treating all CHC-screened patients, regardless of fibrosis, assuming ≤20 000 patients treated/year and priority to ≥F3...
