Hua Jiang, Yu Wu, Binbin Han, Yang Zhang
This work was to investigate the influence of time on the properties of cellulose nanocrystals (CNCs) during the ammonium persulfate (APS) oxidation of hybrid poplar residues (HPHL). The CNCs at the different times were characterized by different techniques. The results showed that CNCs were thinned and shortened with increased oxidation time, and their yield, crystallinity index and zeta potential increased, however, these properties stayed constant after the APS oxidation for 16h. At this time, the CNC yield was more than 50%, and the CNCs had a zeta potential of -48...

PURPOSE: Antipsychotics (APs) are commonly used to manage neuropsychiatric symptoms (NPS) in elderly patients with dementia, even though several large studies have demonstrated an association between AP treatment and increased morbidity and mortality in people with dementia. The aim of this study is to review the scientific literature of the use of AP in the elderly with dementia and to propose an algorithm to assist in decision-making regarding the withdrawal of APs. METHODS: A computerized literature search (MEDLINE: 1966 to December 2016, EMBASE: 1982 to December 2016) was used to locate relevant literature...

We present the case of a patient with primary APS who had a recurrence of thrombotic event while on treatment with rivaroxaban and had to be restarted on warfarin. The current literature on recurrence of thrombotic events in patients with antiphospholipid syndrome (APS) treated with newer oral anticoagulants (NOAC) is also reviewed. Relevant case reports and case series were identified by searching the Medline database using the key words antiphospholipid syndrome, anticoagulants and names of the NOACs, and data on individual patients was abstracted...

PURPOSE OF REVIEW: Antiphospholipid syndrome (APS) is a clinical disorder characterised by thrombosis and/or pregnancy morbidity in the persistence of antiphospholipid (aPL) antibodies that are pathogenic and have pro-coagulant activities. Thrombosis in APS tends to recur and require prophylaxis; however, the stereotypical treatment for APS patients is inadequate and stratification of the thrombotic risks is important as aPL are prevalently observed in various diseases or elderly population...

Previous study has demonstrated that activation of the mammalian target of rapamycin (mTOR) pathway in endothelial cells (ECs) results in the formation of chronic vascular lesions associated with antiphospholipid syndrome (APS). In addition, it has been shown that stimulation of monocytes and ECs by antiphospholipid antibodies (aPL) leads to a prothrombotic and proinflammatory state and up-regulated expression of tissue factor (TF) and inflammatory cytokines. However, the role of mTOR in pathogenic mechanisms of APS remains largely unexplored...

Background/Purpose Long-term anticoagulation is the standard treatment for thrombotic antiphospholipid syndrome (APS). However, in daily practice, the question of withdrawing anticoagulation may arise, without any evidence-based recommendations. This study aimed to assess outcomes in APS patients after anticoagulation withdrawal. Methods Thrombotic APS patients followed in our centre, whose anticoagulation was withdrawn after APS diagnosis, were retrospectively selected, and were match-controlled with patients under anticoagulation, based on sex, age, APS clinical phenotype and disease duration...

BACKGROUND AND OBJECTIVES: Physicians must communicate effectively with patients. Actual patients (APs) rarely evaluate medical students' clinical skills; instead, standardized patients (SPs) provide proxy ratings. It is unclear how well SP ratings mirror AP experiences. The aim of this study was to compare AP and SP assessments of medical students' communication skills and professionalism. We hypothesized that their perspectives would be similar, but distinct, and offer insight about how to more reliably include the patient's voice in medical education...

OBJECTIVE: Trait predisposition to hyperarousal and pre-sleep state hyperarousal are considered key factors in insomnia, but research also supports the role of cognitive and metacognitive processes. Therefore, the aim of this study was to evaluate the relationship between unhelpful sleep-related beliefs, sleep-related metacognition and trait/pre-sleep state arousal in insomnia disorder. METHOD: Sixty-eight subjects with insomnia disorder (DSM-5) and 36 good sleepers were evaluated with a set of questionnaires that included Dysfunctional Beliefs about Sleep scale (DBAS), Metacognitions Questionnaire - Insomnia (MCQI), Arousal Predisposition Scale (APS), and Pre-sleep Arousal Scale (PSAS)...

Efferocytosis by alveolar phagocytes (APs) is pivotal in maintenance of lung homeostasis. Increased efferocytosis by APs results in protection against lethal acute lung injury due to pulmonary infections whereas defective efferocytosis by APs results in chronic lung inflammation. In this report, we show that pulmonary delivery of Bacillus Calmette-Guerin (BCG) significantly enhances efferocytosis by APs. Increased efferocytosis by APs maintains lung homeostasis and protects mice against lethal influenza pneumonia...

OBJECTIVE: Antiphospholipid syndrome (APS) leukocytes exhibit an oxidative perturbation, directly linked to alterations in mitochondrial dynamics and metabolism. This disturbance is related to the patients' prothrombotic status and can be prevented by in vitro treatment with coenzyme Q10. Our aim was to investigate short-term effects of in vivo ubiquinol (reduced coenzyme Q10[Qred]) supplementation on markers related to inflammation and thrombosis in APS through a prospective, randomized, crossover, placebo-controlled trial...

OBJECTIVE: Antimicrobial Stewardship Programs (ASPs) have appeared as very useful tools in order to improve the use of antimicrobial agents. The objective of this study is to assess the impact of an ASP on haematological patients hospitalized in an Intensive Care Unit (ICU). METHODS: A quasi-experimental pre-post intervention study, which included haematological patients admitted to an ICU and assessed by the ASP program during 3 years. The impact of the program on patient evolution was assessed by comparison between the previous period and the intervention period in terms of mortality, mean stay, number of re-hospitalizations, and duration of mechanical ventilation for intubated patients...

The hyperplastic growth of rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLSs) and inflammatory response are pathological hallmarks of RA. It has been reported that Astragalus polysaccharides (APS) possess appreciable anti-inflammatory activity against adjuvant-induced arthritis. Nevertheless, little is known about the role and detailed mechanism underlying the therapeutic effects of APS in RA. This study demonstrated that administration of APS dose-dependently impaired cell viability, increased cell apoptosis by decreasing Bcl-2 expression, increasing Bax expression and Caspase3 activity in IL-1β-stimulated RSC-364 cells and RA-FLS...

Obstetric antiphospholipid syndrome (Obs-APS) is one of the most commonly identified causes of recurrent pregnancy loss and its accurate diagnosis is a requirement for optimal treatment. Some patients do not fulfill the revised Sapporo classification criteria, the original APS classification criteria, and are considered to be non-criteria Obs-APS. In these patients with non-criteria, there is controversy about their inclusion within the spectrum of APS and eventually their treatment as having Obs-APS. A subset of patients may also have clinical characteristics of Obs-APS even though lupus anticoagulant (LA), anticardiolipin antibodies, and anti-β2-glycoprotein I (aβ2GPI) antibodies are consistently negative...

Although catheter ablation is a standard treatment for pediatric arrhythmias, there are no consensus guidelines for follow-up care. This study describes the variation in post-ablation practices identified through a survey of the pediatric and congenital electrophysiology society (PACES). Pediatric and congenital electrophysiology society members were invited to participate in an online survey of post-ablation practices in September 2014. Survey questions targeted routine post-ablation practices for three common arrhythmia substrates: atrioventricular nodal reentry tachycardia, concealed accessory pathways (AP), and manifest APs...
