It is possible to estimate hepatic triglyceride content by calculating the proton density fat fraction (PDFF), using proton magnetic resonance spectroscopy ((1)H-MRS), instead of collecting and analyzing liver biopsies to detect steatosis. However, the current PDFF cut-off value (5%) used to define steatosis by magnetic resonance was derived from studies that did not use histopathology as the reference standard. We performed a prospective study to determine the accuracy of (1)H-MRS PDFF in measurement of steatosis using histopathology analysis as the standard...

An off-line high performance liquid chromatography (HPLC) coupled with chemical methods has been developed to evaluate antioxidant activity of 11 standard polyphenol compounds (SPCs) and vitamin C (Vc) in terms of radical scavenging abilities. The structure-activity relationships of each SPC were also discussed. SPCs showed different abilities in scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis-3-ethyl-benzthiazoline-6-sulphonate (ABTS(+)) and hydroxyl (OH) free radicals. Among SPCs, quercetin and kaempferol, as typical flavonoids, displayed the greatest radical-scavenging activities and even exhibited higher activity in OH radical removal ability than that of Vc...

Keratinocyte carcinoma (KC), which includes basal-cell carcinoma (BCC) and squamous-cell cancer (SCC), has been associated with an increased risk of second primary cancers (SPCs), although the reason for this increase is unknown. We assessed the effects of smoking, alcohol, and obesity prior to the diagnosis of KC on the development of SPCs, as these are well-established risk factors for multiple cancers and may also contribute to the increased risk of SPCs among those with KC. A total of 15,628 women with self-reported KC were identified in the Nurses' Health Study...

Papillary breast lesions are a heterogeneous group of tumors which mainly arise in the central mammary region, ranging from benign to malignant. Among them, solid papillary carcinoma (SPC) represents a very uncommon variant with indolent clinical behavior and excellent prognosis. The categorization of papillary lesions as benign, atypical or malignant is often difficult even for experienced pathologists. Furthermore, for prognostic purposes, to decide whether to consider a lesions as in situ when it is not associated with frank invasive foci of carcinoma may be problematic...

We use flat-histogram Monte Carlo simulations to study how changing the flexibility of soft porous crystals (SPCs) affects their selective adsorption of a binary, size-asymmetric supercritical fluid. Specifically, we consider mesoporous SPCs which have multiple minima in their free energy profiles as a function of pore size such that they are capable of exhibiting polymorphism between a narrow and large pore phase. While specific fluid-pore interactions determine the shape of both pores' selectivity curve as a function of adsorbate pressure, an individual pore tends to selectively adsorb a species based on the size of the adsorbate molecule relative to itself, thereby shifting the pore's selectivity curve relative to its polymorph...

Antihypertensive efficacy of single-pill combinations (SPCs) consisting of a β1 -selective adrenergic blocker with vasodilatory properties via β3 -agonism (nebivolol) and an angiotensin II receptor blocker (valsartan) was demonstrated in an 8-week phase 3 trial (NCT01508026). In this post hoc analysis, seated blood pressure, heart rate, 24-hour ambulatory blood pressure monitoring, plasma aldosterone, estimated glomerular filtration rate, and safety measures were assessed in obese (body mass index >32 kg/m(2) ; n=1823) and nonobese (body mass index <27 kg/m(2) ; n=847) adults with hypertension (stage I or II) treated with nebivolol-valsartan SPCs, nebivolol or valsartan monotherapy, or placebo...

The etiology and pathogenesis of moyamoya disease (MMD) are still obscure. Previous studies indicated that angiogenic chemokines may play an important role in the pathogenesis of the disease. Recently, it was discovered that peripheral blood-derived endothelial colony-forming cells (ECFCs) and smooth muscle progenitor cells (SPCs) have defective functions in MMD patients. Therefore, the interaction of ECFCs and SPCs, the precursors of two crucial cellular components of vascular walls, with some paracrine molecules is an intriguing subject...

I J Bontekoe, P F van der Meer, D de Korte
BACKGROUND AND OBJECTIVES: According to European guidelines, the temperature of whole blood (WB) has to be maintained at 20-24°C until processing within 24 h, but in blood bank practice, WB is frequently held at temperatures between 18-25°C. We aimed to assess the impact of these small temperature deviations on the quality of the blood components. MATERIALS AND METHODS: After rapid cooling, 7 WB units were held overnight at 18°C and 8 units at 25°C, reflecting worst case holding conditions, and separated into a red cell concentrate (RCC), plasma and buffy coat (BC)...

Monna Arvinen-Barrow, Damien Clement
Sport injury rehabilitation has moved from predominately physical treatment to a more holistic care. However, limited research has explored the views and experiences of those involved in such an approach. The purpose of this study was to preliminarily investigate sport psychology consultants' (SPCs') views and experiences of an interprofessional team approach to sport injury rehabilitation. A cross-sectional online survey previously used with athletic trainers was distributed via a US-based sport/exercise psychology list-serve (N = 1245)...

Dar Weiss, Oren M Rotman, Shmuel Einav
Short peripheral catheter thrombophlebitis (SPCT), a sterile inflammation of the vein wall, is the most common complication associated with short peripheral catheters (SPCs) and affects up to 80% of hospitalized patients receiving IV therapy. Extensive research efforts have been devoted for improvement and optimization of the catheter material, but means for examination of any novel design are limited, inaccurate and require costly comprehensive pre-clinical and clinical trials. Therefore, there is a conclusive need for a reliable quantitative method for evaluation of SPCT, in particular for research purposes examining the thrombophlebitis-related symptoms of any novel catheter design...

Purpose Male cancer survivors have a higher risk of cancer than the general population, which might be caused by an increased prevalence of obesity or susceptibility to obesity-related carcinogenesis. We assessed the effects of obesity before the diagnosis of a first cancer on the development of secondary primary cancers (SPCs). Methods The study population consisted of 239,615 Korean male cancer survivors between January 2003 and December 2010. Incident SPCs were assessed throughout follow-up until December 2011...

OBJECTIVE: Despite advances in suicide prevention implemented throughout the US Department of Veterans Affairs (VA) including the hiring of Suicide Prevention Coordinators (SPCs) at every VA hospital, enhanced monitoring, and the availability of 24-hour crisis hotline services, suicide by veterans remains a critical problem affecting 20 veterans daily. Few empirically based treatment strategies for suicide prevention for postdeployment military personnel exist. This study aimed to test whether dialectical behavior therapy (DBT), one of the few psychosocial treatments with proven efficacy in diminishing suicidal behavior in individuals with personality disorder, can be applied to veterans irrespective of personality diagnosis...

The clinical relevance of the drug-drug interaction simvastatin and amlodipine is appraised controversially by german simvastatin Summary of Product Characteristics (SPCs) and different drug interaction databases. Results of clinical trials have shown that simultaneous administration of simvastatin and amlodipine can increase simvastatin bioavailability. However, it is unclear whether this increase is associated with a higher risk for adverse drug events. So far there is no evidence that the combination might increase cases of myopathy or rhabdomyolysis...

Cancer survival rates are increasing, and as a result, more cancer survivors are exposed to the risk of developing a second primary cancer (SPC). It has been hypothesized that one of the underlying mechanisms for this risk could be mediated by variations in insulin-like growth factor-1 (IGF-1). This review summarizes the current epidemiological evidence to identify whether IGF-1 plays a role in the development of SPCs. IGF-1 is known to promote cancer development by inhibiting apoptosis and stimulating cell proliferation...

Quetiapine is a low-affinity dopamine D2 receptor antagonist, approved for the treatment of bipolar disorder and schizophrenia in children and adolescents by the Food and Drug Administration, but not by European Medicine Agency. Although knowledge of adverse drug reactions in children and adolescents is scarce, quetiapine is increasingly being used for youth in Denmark. The aim of this case study is to discuss adverse drug events (ADEs) spontaneously reported to the Danish Medicines Agency on quetiapine used in the pediatric population in relation to adversive drug reactions (ADRs) reported in the European Summary of Product Characteristics (SPCs)...
