BACKGROUND: We examined whether a program combining cognitive-behavioural therapy (CBT), vestibular rehabilitation (VR) and psychoeducation is equally effective in improving psychometric measures in patients with dizziness independent of a balance deficit. Measures of patients with dizziness only (DO) were compared to those of patients also having a quantified balance deficit (QBD). METHODS: 32 patients (23 female, 9 male) with persistent dizziness were analysed as 2 groups based on stance and gait balance control: those with QBD (pathological balance) or DO (normal balance)...

In industrialized countries, Alzheimer's disease represents the most devastating neurodegenerative disorder in elderly people and the search for a disease modifying agent is still justified by this unmet need. Several possible targets have been explored to find an appropriate drug therapy, and in this review dual inhibitors of beta secretase and glycogen synthase kinase 3, recently reported in literature, will be appraised. Applying a ligand-based approach, the triazinone core emerged as a suitable scaffold to simultaneously bind the aspartic dyad of BACE-1 and the ATP site of GSK-3β, leading to a series of small molecules endowed with a balanced micromolar affinity and a promising pharmacokinetic profile...

Extracellular ATP interacts with purinergic type 2 (P2) receptors and elicits many crucial biological functions. Extracellular ATP is sequentially hydrolyzed to ADP and AMP by the actions of defined nucleotidases, such as CD39, and AMP is converted to adenosine, largely by CD73, an ecto-5'-nucleotidase. Extracellular adenosine interacts with P1 receptors and often opposes the effects of P2 receptor activation. The balance between extracellular ATP and adenosine in the blood and extracellular fluid is regulated chiefly by the activities of CD39 and CD73, which constitute the CD39-adenosinergic axis...

INTRODUCTION: Despite advances in treatment, notably in systemic therapy, the prognosis of pancreatic adenocarcinoma (PADC) remains dismal. Stereotactic body radiotherapy (SBRT) is an emerging tool in the complex management of PADC. We review outcomes of SBRT for PADC at our institution. METHODS: We reviewed patients treated with SBRT for either unresectable PADC or locally recurrent PADC after surgery. Treatment was delivered using a robotic radiosurgery system with respiratory tracking...

BACKGROUND: Mortality in children remains high in sub-Saharan African hospitals. While antimalarial drugs, antibiotics and other definitive treatments are well understood, the role of emergency care with supportive therapies, such as maintaining normal glucose and electrolyte balances, has been given limited attention. Hypoglycaemia is common in children admitted to hospital in low-income settings. The current definition of hypoglycaemia is a blood glucose level < 2.5 mmol/L in a well-nourished child...

OBJECTIVE: After radioiodine therapy of differentiated thyroid cancer (DTC) patients, whole body scintigraphy (WBS) is standard procedure before releasing the patient from the hospital. A common problem is the precise localization of regions where the iod-avide tissue is located. Sometimes is practically impossible to perform precise topographic localization of such regions. METHOD: In order to face this problem, we have developed a low-cost Vision-Fusion system for web-camera image acquisition simultaneously with routine scintigraphic whole body acquisition including the algorithm for fusion of images given from both cameras...

PURPOSE OF REVIEW: The increasing incidence of acute kidney injury has the immediate effect of a growing need for renal replacement therapy (RRT). Shedding light on the questions of who, when, why, and how RRT should be performed is difficult to accomplish because of ambiguous study results, poor quality evidence, and low standardization. RECENT FINDINGS: Critically ill patients are exposed to multiple factors known to deteriorate kidney function. Especially severe fluid overload is strongly associated with worse outcome and may be considered as a trigger for initiating RRT...

Mesenchymal stem cells (MSCs) are multi-potent cells that are self-renewable and possess the potential to differentiate into multiple lineages. Several studies demonstrated that MSCs could regulate a Th17/Treg balance and could be a potential therapeutic target for Rheumatoid Arthritis (RA). A20 is highly expressed in many cell types after the stimulation of TNF-α, where it may inhibit pro-inflammatory cytokine secretion. However, the expression of A20 in BM-MSCs in RA is not fully understood. In our study, we found that A20 was decreased in RA patients' bone marrow MSCs (BM-MSCs), and with more IL-6 secretion, the balance of Th17/Treg was broken...

The embryonic formation of midbrain dopaminergic (mDA) neurons in vivo provides critical guidelines for the in vitro differentiation of mDA neurons from stem cells, currently being developed for Parkinson's disease cell replacement therapy. Bone morphogenetic protein (BMP)/SMAD inhibition is routinely used during early steps of stem cell differentiation protocols, including for the generation of mDA neurons. However, the function of the BMP/SMAD pathway for in vivo specification of mammalian mDA neurons is virtually unknown...

BACKGROUND: Proton pump inhibitors are often used in critically ill patients to prevent gastrointestinal bleeding despite limited evidence for benefit. Patients with acute kidney injury requiring renal replacement therapy (RRT) are at high risk of gastrointestinal bleeding as (pre-)uremia induces coagulopathy through effects on platelets and coagulation cascades. No high-quality randomized clinical trials have previously assessed the benefits and harms of prophylactic proton pump inhibitor use in this high-risk population of adult critically ill patients...

The newer oral therapies for type 2 diabetes (T2DM); dipeptidyl peptidase-4 (DPP-4) inhibitors and sodium glucose cotransporter 2 (SGLT2) inhibitors have advantages over older agents. DPP-4 inhibitors are weight neutral, and have few adverse effects. SGLT2 inhibitors have additional benefits; weight loss, blood pressure reduction, cardiovascular risk reduction, and renoprotective effects. SGLT2 inhibitors, have increased risk of urogenital infections and possible risk of "euglycaemic" diabetic ketoacidosis...

BACKGROUND: Recombinant von Willebrand factor (rVWF), which was licensed in the United States in 2015, has the multimeric distribution of freshly secreted VWF with ultralarge (UL) and high molecular weight multimers (HMWM) from endothelial cells and megakaryocytes since it has never been exposed to ADAMTS13 or any other proteolytic enzyme. Measurement of closure time (CT) using the platelet function analyzer-200 (PFA-200) is highly sensitive to the presence of UL VWF multimers in added VWF concentrates...

Stroke prevention in atrial fibrillation (AF) has reached an exciting phase with a plethora of newer, potentially more efficacious and safer agents being introduced for physicians to select from. Dabigatran belongs to a class of anticoagulants called direct thrombin inhibitors, while rivaroxaban, apixaban, and edoxaban are direct Factor Xa inhibitors. Purely from a therapeutic endpoint perspective-based on the action of anticoagulants in reducing cardioembolic stroke-in clinical trials, one should look at whether a new anticoagulant in patients with AF prevents ischemic stroke...

Improved treatments are needed for hemophilia A and B, bleeding disorders affecting 400,000 people worldwide. We investigated whether targeting protein S could promote hemostasis in hemophilia by re-balancing coagulation. Protein S is an anticoagulant acting as cofactor for activated protein C and tissue factor pathway inhibitor (TFPI). This dual role makes PS a key regulator of thrombin generation. Here, we report that targeting protein S rebalances coagulation in hemophilia. Protein S gene targeting in hemophilic mice protected them against bleeding, especially when intra-articular...

The imbalance of Th1/Th2 cytokines is well known in recurrent spontaneous abortion (RSA) mouse model. Mesenchymal stem cells (MSCs) possess potent immunoregulatory properties that could modulate the Th1 cytokine responses in benefit of Th2 types. In this study, we aimed to analyze the local and systemic balance of Th1/Th2 cytokines following MSCs therapy. Syngeneic adipose derived MSCs were administered to abortion prone mice during the implantation window. The abortion rate was determined and IL-4, IL-6, IL-12, IL-2, IFN-γ and GM-CSF gene expression was evaluated by Real-Time-PCR in decidual and placental tissues of pregnant mice at day 13...

BACKGROUND: Repetitive sensory stimulation (RSS) adapts the timing of stimulation protocols used in cellular studies to induce synaptic plasticity. In healthy subjects, RSS leads to widespread sensorimotor cortical reorganization paralleled by improved sensorimotor behavior. Here, we investigated whether RSS reduces sensorimotor upper limb impairment in patients with subacute stroke more effectively than conventional therapy. METHODS: A single-blinded sham-controlled clinical trial assessed the effectiveness of RSS in treating sensorimotor deficits of the upper limbs...
