EML4-ALK gene fusion (inv2(p21p23)) of non-small cell lung cancer (NSCLC) predisposes to tyrosine kinase inhibitor treatment. One of the gold standard diagnostics is the dual color (DC) break-apart (BA) FISH technique, however, the unusual closeness of the involved genes has been suggested to raise likelihood of random co-localization (RCL) of signals. Although this is suspected to decrease sensitivity (often to as low as 40-70%), the exact level and effect of RCL has not been revealed thus far. Signal distances were analyzed to the 0...

INTRODUCTION: Factor VIII (FVIII) antibody formation is the greatest clinical and laboratory challenge within the haemophilia centre. The Nijmegen-Bethesda assay (NBA) is the gold standard for inhibitor quantification, but affected by pre-analytical variables including a patient's FVIII activity (FVIII:C). Pre-analytical heat treatment (PHT) provides a methodology for inhibitor testing when measurable FVIII:C is present. METHODS: We evaluated the effect of different PHT conditions (time/temperature) on FVIII:C as well as on potency of inhibitory activity in samples containing FVIII:C (endogenous pooled plasma and exogenous recombinant FVIII (rFL-FVIII) concentrate) or FVIII inhibitor...

INTRODUCTION: Clinical assessment of mid-dermal burns can be challenging. Currently, laser Doppler imaging (LDI) is the gold standard adjunct in the assessment of burn injuries. Although LDI has demonstrated reliable accuracy, it poses various limitations in routine use including cost and ease of use. In comparison, spectrophotometric intracutaneous analysis (SIA) is a relatively cheaper technique, which can be carried out using a modified digital camera that enables easy image acquisition...

BACKGROUND & AIMS: Measuring resting energy expenditure (REE) via indirect calorimetry (IC) in intensive care unit (ICU) patient is the gold standard recommended by guidelines. However technical difficulties hinder its use and predictive equations are largely used instead. We sought to validate commonly used equations using a large cohort of patients. METHODS: Patients hospitalized from 2003 to 2015 in a 16-bed ICU at a university-affiliated, tertiary care hospital who had IC measurement to assess caloric targets were included...

Molecular genetic technologies are used to aid in diagnosis and treatment of borderline melanocytic tumors as an adjuvant to the gold standard histopathologic evaluation. A specific set of fluorescence in situ hybridization probes is widely used to aid in diagnosing challenging melanocytic lesions. New melanoma probe cocktails have revealed increased sensitivity and specificity in ambiguous melanocytic cases. Array comparative genomic hybridization is a more complex technology used for the work-up of diagnostically problematic Spitzoid melanocytic proliferations...

BACKGROUND: Information on causes of death (COD) is crucial for measuring the health outcomes of populations and progress towards the Sustainable Development Goals. In many countries such as Vietnam where the civil registration and vital statistics (CRVS) system is dysfunctional, information on vital events will continue to rely on verbal autopsy (VA) methods. This study assesses the validity of VA methods used in Vietnam, and provides recommendations on methods for implementing VA validation studies in Vietnam...

The determination of gallic acid (GA) and uric acid (UA) is essential due to their biological properties. Numerous methods have been reported for the analysis of GA and UA in various real samples. However, the development of a simple, rapid and practical sensor still remains a great challenge. Here, a carbon paste electrode (CPE) was modified by nanocomposite containing zirconia nanoparticles (ZrO2 NPs), Choline chloride (ChCl) and gold nanoparticles (AuNPs) to construct ZrO2 -ChCl-AuNPs/CPE as electrochemical sensor for the simultaneous electro-oxidation of GA and UA...

Visualization of amastigotes in lymph nodes, bone marrow, and other tissues samples remains the gold standard method for the diagnosis of visceral leishmaniasis (VL) in humans. This gold standard diagnostic method uses a technically challenging microscopy procedure that is often not accessible in many places in the world where VL is endemic. Here, we report the current systematic review and meta-analysis to evaluate whether urine is a reliable clinical sample for diagnosis of human VL. Data were extracted from ten available databases during the period from 2002 to 2017...

Fungal cells change shape in response to environmental stimuli, and these morphogenic transitions drive pathogenesis and niche adaptation. For example, dimorphic fungi switch between yeast and hyphae in response to changing temperature. The basidiomycete Cryptococcus neoformans undergoes an unusual morphogenetic transition in the host lung from haploid yeast to large, highly polyploid cells termed Titan cells. Titan cells influence fungal interaction with host cells, including through increased drug resistance, altered cell size, and altered Pathogen Associated Molecular Pattern exposure...

INTRODUCTION AND OBJECTIVE: Robot-assisted sacral colpopexy (RASC) is a fast growing approach for surgeons treating patients with advanced stage pelvic organ prolapse (POP). Open abdominal sacral colpopexy has been the gold standard for advanced POP but requires longer hospital stays and a much larger incision. The indications, preoperative preparation, operative positioning, and operative steps are detailed, and an accompanying video shows the approach. METHODS: RASC can be broken down into 11 steps and the reader will be able to reference the article to the corresponding portion of the video...

Urinary incontinence (UI) is a common symptom affecting almost one-third of adult women. UI can occur because of hypermobility or intrinsic sphincter deficiency of the urethra. Regardless its etiology, it is associated with poor quality of life and most of the incontinent women develop symptoms such as anxiety, depression, and social isolation over time. The synthetic midurethral sling (MUS) was first introduced in 1995 and quickly became the gold standard treatment for women with stress UI because of intrinsic sphincter deficiency and/or urethral hypermobility...

Historically, the gold standard for management of ureteropelvic junction obstruction (UPJO) has been open pyeloplasty. However, continued technological and surgical advances have ultimately led to the robotic approach. Continued advances in minimally invasive surgery have led to shorter hospital stays and hastened recovery. Here we present our step by step guide and video to robotic-assisted laparoscopic pyeloplasty.
