A liquid chromatography-tandem mass spectrometry method using a pentafluorophenylpropyl-bonded silica column was developed to simultaneously quantify twenty Amadori products (APs), including N-(1-Deoxy-d-fructosyl-1-yl)-l-isoleucine (Fru-Ile) and N-(1-Deoxy-d-fructosyl-1-yl)-l-leucine (Fru-Leu), in soy sauce, without the need for an ion-pairing reagent or sample derivatization. The method was applied to six types of soy sauce, to determine the total AP levels and the levels of individual APs. The level of total APs widely varied between the eight samples, from 358mg/L to 24347mg/L...

Even with advanced inverse-planning techniques, radiation treatment plan optimization remains a very time-consuming task with great output variability, which prompted the development of more automated approaches. One commercially available technique mimics the actions of experienced human operators to progressively guide the traditional optimization process with automatically created regions of interest and associated dose-volume objectives. We report on the initial evaluation of this algorithm on 10 challenging cases of locoreginally advanced head and neck cancer...

The antiphospholipid syndrome (APS) is a multisystem autoimmune disease characterized by recurrent fetal loss and thromboembolic events associated with the presence of elevated titres of antiphospholipid antibodies (aPL). The purpose of this review is to summarize what is currently known about the diagnosis and treatment of pediatric APS, to highlight key differences between APS presenting in adults versus children throughout, and to identify areas where future research is needed.

Persistent serum positivity for antiphospholipid antibodies (aPL) is required to diagnose antiphospholipid syndrome (APS), an autoimmune disease characterized by recurrent vascular thrombosis and/or pregnancy morbidity. The current therapeutic management of patients with thrombotic APS aims at preventing recurrences and long-term complications by attenuating the procoagulant state. There is overall consensus to reserve moderate-intensity anticoagulation to aPL-positive patients with a previous venous thrombosis; the therapeutic options for those with a history of arterial event comprise antiplatelet agents and high-intensity anticoagulation...

Catastrophic antiphospholipid syndrome (CAPS) is a rare, life-threatening disease. In 1992, Asherson defined it as a widespread coagulopathy related to the antiphospholipid antibodies (aPL). CAPS requires rapid diagnosis and prompt initiation of treatment. Areas covered: This paper discusses all aspects of CAPS, including its pathophysiology, clinical manifestations, diagnostic approaches, differential diagnoses, management and treatment of relapsing CAPS, and its prognosis. To obtain the information used in this review, scientific databases were searched using the key words antiphospholipid antibodies, catastrophic antiphospholipid syndrome, hemolytic anemia, lupus anticoagulant, and thrombotic microangiopathic hemolytic anemia...

We report on a female patient with confirmed secondary antiphospholipid syndrome (APS) due to underlying systemic lupus erythematosus (SLE). Despite a thromboplastin time within the normal range (international normalized ratio, INR) under treatment with a vitamin K antagonist (VKA), a recurrent thrombotic event occurred, this time as pulmonary embolism due to bilateral deep vein thrombosis. Despite an INR value in the therapeutic range, clotting factors II, VII, IX and X were found to be insufficiently decreased suggesting inefficient anticoagulation...

Background -Antiphospholipid syndrome (APS) is characterized by recurrent thrombosis and/or gestational morbidity in patients with antiphospholipid autoantibodies (aPL). Predictive value of the presence of aPL is low and new markers are necessary to identify aPL carriers at higher risk and take preventive measures on them.The presence of circulating immune complexes of IgA bound to Beta2-glycoprotein-I (B2A-CIC) has been associated with occurrence of acute thrombotic events (TEV). In this work we study its possible predictive value for appearance of TEV in patients who are going to undergo transplant surgery, a well-known trigger of TEV in aPL carriers 94...

PURPOSE OF REVIEW: To identify the different indications for the treatment of neurologic disorders with the potassium channel blockers 4-aminopyridine (4-AP) and 3,4-diaminopyridine (3,4-DAP). RECENT FINDINGS: 4-AP is an effective symptomatic treatment for downbeat nystagmus (DBN), episodic ataxia type 2 (EA2) (5-10 mg TID), and impaired gait in multiple sclerosis (MS) (10 mg BID). 3,4-DAP (5 mg/d-20 mg TID) improves symptoms in Lambert-Eaton myasthenic syndrome (LEMS) (randomized placebo-controlled trials for all 4 entities)...

Obstetrical APS is defined by thrombosis and/or obstetrical morbidity associated with persistent antiphospholipid antibodies. The aspirin and low molecular weighted heparin combination dramatically improved obstetrical outcome in APS patients. Several factors could be associated with obstetrical prognosis, as previous history of thrombosis, associated SLE, the presence of lupus anticoagulant and triple positivity of antiphospholipid antibodies. Obstetrical APS with isolated recurrent miscarriages is mostly associated with isolated anticardiolipids antibodies and have better obstetrical outcome...

BACKGROUND: Atypical parkinsonian conditions such as multiple system atrophy (MSA), progressive supranuclear palsy (PSP), corticobasal syndrome (CBS) and Dementia with Lewy bodies (DLB) comprise 10-15% of parkinsonian syndromes. Misdiagnosis with Parkinson disease (PD) and within the entities is common, given the absence of reliable biomarkers. However a correct diagnosis is not only important in clinical practice, but also crucial for any trial attempting to identify biomarkers or new treatments...

The current mainstay of the treatment and secondary thromboprophylaxis of thrombotic antiphospholipid syndrome (APS) is anticoagulation with warfarin or other vitamin K antagonists (VKAs). In addition to their well-known limitations, VKAs are often problematic in APS patients because of the variable sensitivity of thromboplastins to lupus anticoagulant. As a result, the international normalized ratio may not accurately reflect the intensity of anticoagulation. Direct oral anticoagulants (DOACs) are established as therapeutic alternatives to VKAs for a wide range of indications, including the treatment and secondary prevention of venous thromboembolism...

Astragalus polysaccharide (APS) is a bioactive extract of Astragalus membranaceus (AM), which possess a wide range of medicinal benefits, including anti-inflammatory, anti-oxidative, anti-tumor and anti-diabetic effects. The present work evaluated the therapeutic effect of APS and its potential mechanisms in a mouse model of dextran sulfate sodium (DSS)-induced colitis. The APS treatment led to significant improvements in colitis disease activity index (DAI) and histological scores, as well as significantly increased weight and colon length in mice as compared to the control group...

Peroxisome proliferator-activated receptor γ (PPARγ) is a ligand-dependent transcription factor involved in many aspects of metabolism, immune response, and development. Total-body deletion of the two Pparg alleles provoked generalized lipoatrophy along with severe type 2 diabetes. Herein, we explore the appearance and development of structural and functional alterations of the kidney, comparing Pparg null-mice to their littermate controls (carrying Pparg floxed alleles). We show that renal hypertrophy and functional alterations with increased glucosuria and albuminuria are already present in 3 weeks-old Pparg null-mice...

STUDY OBJECTIVE: A substantial proportion of antipsychotic (AP) use in veterans is for nonapproved indications (i.e., off-label prescribing). Not all off-label use is necessarily detrimental to patients, however, and in certain situations, off-label prescribing could be considered justifiable. The objective of this study was to determine the extent to which off-label AP prescribing in a veteran population was potentially appropriate. DESIGN: Expert panel and retrospective analysis...

Colostrum is the main external resource providing piglets with nutrients and maternal immune molecules. Astragalus polysaccharides (APS) have been used as immunopotentiators in vitro and several animal models. This study aimed to determine the effects of APS on immune factors in sow colostrum and milk. The sow diet was supplemented with APS one week before the expected delivery date. Colostrum and milk were collected and designated as 0 h- (onset of parturition), 12 h-, and 24 h-colostrum and 36 h-milk postpartum...

BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) and other psychotropics are receiving increasing attention due to reports on inhibition of thrombocyte function and an increased bleeding risk in surgical settings. Studies in total hip and total knee arthroplasty (THA and TKA, respectively) have shown conflicting results, questioning whether the potential increased bleeding risk is of clinical importance. STUDY DESIGN AND METHODS: Prospective consecutive collection of data on preoperative comorbidity in patients undergoing primary unilateral THA or TKA was cross-referenced with regional transfusion databases and The Danish National Database of Reimbursed Prescriptions for information regarding blood transfusions and psychopharmacologic treatment...
