#1
Luigi Cinquanta, Desré Ethel Fontana, Nicola Bizzaro
Diagnostic technology is rapidly evolving, and over the last decade, substantial progress has been made even for the identification of antibodies, increasingly approaching this type of diagnostic to that of automated clinical chemistry laboratory. In this review, we describe the analytical and diagnostic characteristics of chemiluminescence technology in its strength and in its applicability for a more rapid and accurate diagnosis of autoimmune diseases. The wide dynamic range, greater than that of immunoenzymatic methods, the high sensitivity and specificity of the results expressed in quantitative form, the high degree of automation and the clinical implications related to the reduction in the turnaround time, and the ability to run a large number of antibody tests (even of different isotypes), directed towards large antigenic panels in random access mode, make this technology the most advanced in the clinical laboratory, with enormous repercussions on the workflow and on the autoimmunology laboratory organisation...

Rapid, safe and effective arterial recanalisation to restore blood flow and improve functional outcome remains the primary goal of hyperacute ischaemic stroke management. The benefit of intravenous thrombolysis with recombinant tissue-type plasminogen activator for patients with severe stroke due to large artery occlusion is limited; early recanalisation is generally less than 30% for carotid, proximal middle cerebral artery or basilar artery occlusion. Since November 2014, nine positive randomised controlled trials of mechanical thrombectomy for large vessel occlusion in the anterior circulation have led to a revolution in the care of patients with acute ischaemic stroke...

David R Schreier, Christina Banks, Johannes Mathis
Road traffic injuries are projected to be the leading cause of death for those aged between 15 and 29 years by the year 2030, and sleepiness is estimated to be the underlying cause in up to 15-20% of all motor vehicle accidents. Sleepiness at the wheel is most often caused by socially induced sleep deprivation or poor sleep hygiene in otherwise healthy individuals, medical disorders, or the intake of drugs. Validated methods for objectifying sleepiness are urgently sought, particularly in the context of driving...

BACKGROUND: Due to the multilineage differentiation ability and paracrine role of adipose-derived stem cells (ASCs) for bladder defect repair, various scaffolds have been applied in combination with ASCs to promote bladder regeneration and restore bladder function. However, the low survival rate of ASCs and the difficulty of promoting bladder functional recovery are still unsolved. To explore these problems, we investigated the feasibility of a novel scaffold seeded with ASCs in a rat model of bladder augmentation...

RNA viruses cause significant human pathology and are responsible for the majority of emerging zoonoses. Mainstream diagnostic assays are challenged by their intrinsic diversity, leading to false negatives and incomplete characterisation. New sequencing techniques are expanding our ability to agnostically interrogate nucleic acids within diverse sample types, but in the clinical setting are limited by overwhelming host material and ultra-low target frequency. Through selective host RNA depletion and compensatory protocol adjustments for ultra-low RNA inputs, we are able to detect three major blood-borne RNA viruses - HIV, HCV and HEV...

Glucocorticoid eye drops are one of the most widely used medications in ophthalmology. However, little is known about the effects of glucocorticoids on corneal epithelial cells that are directly exposed to topically-administered glucocorticoids. Here we investigated the effects of prednisolone, a synthetic glucocorticoid analogue frequently used in the clinic, on corneal epithelial cells. Results showed that prednisolone decreased survival of corneal epithelial cells by inhibiting proliferation and inducing apoptosis in a dose-dependent manner...

The aim of this case-control study was to examine differences in neural correlates of pain facilitatory and inhibitory mechanisms between acute low back pain patients and healthy individuals. Pressure pain tolerance (PPT), electrical pain detection thresholds (EDT), pain ratings to repetitive suprathreshold electrical stimulation (SES) and conditioned pain modulation (CPM) were assessed in 18 patients with acute low back pain (LBP) and 18 healthy controls (CTRL). Furthermore, event-related potentials (ERPs) in response to repetitive SES were obtained from high-density electroencephalography...

BACKGROUND CONTEXT: Percutaneous endoscopic discectomy (PED) is a minimally invasive procedure for the surgical treatment of lumbar disc herniation (LDH). It can be performed under local anesthesia and requires a skin incision of only 8 mm, with minimal disruption of the spinal structures including ligaments and muscles. However, performing PED with a transforaminal approach (TF-PED) for the lower lumbar spine is associated with some anatomical problems such as interference from the iliac crest...

BACKGROUND: Evidence is urgently needed from complex emergency settings to support efforts to respond to the increasing burden of diabetes mellitus (DM). We conducted a qualitative study of a new model of DM health care (Integrated Diabetic Clinic within an Outpatient Department [IDC-OPD]) implemented by Médecins Sans Frontières (MSF) in Mweso Hospital in eastern Democratic Republic of Congo (DRC). We aimed to explore patient and provider perspectives on the model in order to identify factors that may support or impede it...

Moral distress, according to Andrew Jameton's highly influential definition, occurs when a nurse knows the morally correct action to take but is constrained in some way from taking this action. The definition of moral distress has been broadened, first, to include morally challenging situations that give rise to distress but which are not necessarily linked to nurses feeling constrained, such as those associated with moral uncertainty. Second, moral distress has been broadened so that it is not confined to the experiences of nurses...

In developed countries, caesarean section (CS) rates continue to escalate and in Ireland nearly one in three women are now delivered by CS. The purpose of this study was to compare the management of women after one previous CS in two large Dublin maternity hospitals with the management in two other well-resourced countries. Data were analysed for Dublin, Massachusetts in the United States, and Hesse in Germany. It was found that since 1990, the CS rate in Dublin has increased by much more than in the other areas...

A significant portion of patients diagnosed with vitelliform macular dystrophy (VMD) do not carry causative mutations in the classic VMD genes BEST1 or PRPH2. We therefore performed a mutational screen in a cohort of 106 BEST1/PRPH2-negative VMD patients in two genes encoding secreted interphotoreceptor matrix proteoglycans-1 and -2 (IMPG1 and IMPG2). We identified two novel mutations in IMPG1 in two simplex VMD cases with disease onset in their early childhood, a heterozygous p.(Leu238Pro) missense mutation and a homozygous c...

BACKGROUND: The cause for discrepancy in the clinical presentation and outcome of coronary artery disease (CAD) between men and women is not established. Different prevalences of risk factors or specific sex-related atherosclerotic aspects have been advocated as possible explanations. We investigated coronary plaque morphology looking at possible differences in plaque vulnerability between men and women with stable CAD. PATIENTS AND METHODS: We retrospectively collected and analyzed clinical data and coronary plaque morphology by frequency-domain optical coherence tomography in men and women with stable CAD...

Kidney transplantation (KTx) represents the best available treatment for patients with end-stage renal disease. Still, full benefits of KTx are undermined by acute rejection (AR). The diagnosis of AR ultimately relies on transplant needle biopsy. However, such an invasive procedure is associated with a significant risk of complications and is limited by sampling error and interobserver variability. In the present review, we summarize the current literature about non-invasive approaches for the diagnosis of AR in kidney transplant recipients (KTRs), including in vivo imaging, gene expression profiling and omics analyses of blood and urine samples...

We report a case of Candida albicans endogenous endophthalmitis treated with intravitreal caspofungin. The patient was a known case of acute lymphoblastic leukemia on chemotherapy and presented to us with features suggestive of endogenous endophthalmitis. He was treated initially with intravenous (IV) caspofungin and intravitreal amphotericin B. Patients condition worsened after IV caspofungin was replaced by amphotericin B necessitating a core vitrectomy. The patient was given the option of off-label caspofungin intravitreal injection for which the patient consented...

BACKGROUND: Serum creatinine, urea, and cystatin-c are standardly used for the evaluation of renal function in the clinic. However, some patients have chronic kidney disease but still retain kidney function; a conventional serum index in these patients can be completely normal. Serum amino acid levels can reflect subtle changes in metabolism and are closely related to renal function. Here, we investigated how amino acids change as renal impairment increases. METHODS: Subjects were divided into three groups by renal function glomerular filtration rate: healthy controls, patients with chronic kidney disease with normal kidney function, and patients with chronic kidney disease with decreased kidney function group...
