Magnetic resonance imaging (MRI) with a gadolinium-based contrast agent is the gold standard for high-grade gliomas (HGGs). The compound 5-aminolevulinic acid (5-ALA) undergoes a high rate of cellular uptake, particularly in cancer cells. In addition, fluorescence-guided resection with 5-ALA is widely used for imaging HGGs. 5-ALA is water soluble, while protoporphyrin IX (PpIX) is water insoluble. It was speculated whether converting from 5-ALA to PpIX may relatively increase intracellular water content, and consequently, might enhance the T2 signal intensity in HGG...

PURPOSE: Non-small cell lung cancer (NSCLC) patient radiation therapy (RT) is planned without consideration of spatial heterogeneity in lung function or tumor response. We assessed the dosimetric and clinical feasibility of functional lung avoidance and response-adaptive escalation (FLARE) RT to reduce dose to [(99m) Tc]MAA-SPECT/CT perfused lung while redistributing an escalated boost dose within [(18) F]FDG-PET/CT-defined biological target volumes (BTV). METHODS: Eight stage IIB-IIIB NSCLC patients underwent FDG-PET/CT and MAA-SPECT/CT treatment planning scans...

BACKGROUND: Opioids may influence the development of Alzheimer's disease (AD). Some studies have observed AD pathology in the brains of opioid abusers. No study has examined the association between prescription opioid use and dementia-related neuropathologic changes. OBJECTIVE: To examine the relationship between prescription opioid or NSAID use and dementia-related neuropathologic changes. METHODS: Within a community-based autopsy cohort (N = 420), we ascertained opioid and nonsteroidal anti-inflammatory drug (NSAID) use over a 10-year period from automated pharmacy data and calculated total standardized daily doses (TSDDs)...

AIM: Selective androgen receptor modulators (SARMs) induce anabolic effects on muscle without the adverse effects of androgenic steroids. In this first-in-human study, we report safety, tolerability, pharmacokinetics (PK), and pharmacodynamics of the SARM GSK2881078. METHODS: In Part A, healthy young men (n = 10) received a single dose of study drug (0 mg, 0.05 mg, 0.1 mg, 0.2 mg GSK2881078 or matching-placebo).

A highly sensitive analytical method was developed to study the in vivo metabolism of paeoniflorin, one of the most principal components in traditional Chinese medicine. After hydrolyzation with sulfatase, the epimer metabolites 7S-paeonimetabolin I and 7R-paeonimetabolin I of paeoniflorin in rat plasma were successfully detected and well separated by LC-MS following picolinoyl derivatization for the first time. Borneol was used as the internal standard to quantify 7S-paeonimetabolin I and 7R-paeonimetabolin I in rat plasma...

BACKGROUND: Dietary habits are major contributors to coronary heart disease, stroke, and diabetes. However, comprehensive evaluation of etiologic effects of dietary factors on cardiometabolic outcomes, their quantitative effects, and corresponding optimal intakes are not well-established. OBJECTIVE: To systematically review the evidence for effects of dietary factors on cardiometabolic diseases, including comprehensively assess evidence for causality; estimate magnitudes of etiologic effects; evaluate heterogeneity and potential for bias in these etiologic effects; and determine optimal population intake levels...

OBJECTIVE: The aim of the study is to investigate the potential contribution of the iodine quantitative parameters of dual-phase dual-energy computed tomography (DECT) scanning for chemoradiotherapy (CRT) response monitoring for cervical cancer. METHODS: Patients who were pathologically certified having cervical cancer and intended for concurrent radiotherapy and chemotherapy were prospectively included in our study. Contrast-enhanced DECT scanning was performed before CRT, which was repeated after 1 month of therapy, using a dual-source CT scanner onset...

OBJECTIVE: The aim of this study was to compare image quality and radiation dose of coronary computed tomography (CT) angiography performed with dual-source CT scanner using 2 different protocols in patients with atrial fibrillation. METHODS: Forty-seven patients with AF underwent 2 different acquisition protocols: double high-pitch (DHP) spiral acquisition and retrospective spiral acquisition. The image quality was ranked according to a qualitative score by 2 experts: 1, no evident motion; 2, minimal motion not influencing coronary artery luminal evaluation; and 3, motion with impaired luminal evaluation...

BACKGROUND: Opioid dependence (OD) is an increasing clinical and public health problem worldwide. International guidelines recommend opioid substitution treatment (OST), such as methadone and buprenorphine, as first-line medication treatment for OD. A negative aspect of OST is that the medication used can be diverted both through sale on the black market, and the unsanctioned use of medications. Daily supervised administration of medications used in OST has the advantage of reducing the risk of diversion, and may promote therapeutic engagement, potentially enhancing the psychosocial aspect of OST, but costs more and is more restrictive on the client than dispensing for off-site consumption...

Small-cell lung cancer (SCLC) accounts for 13% of all lung tumours. The standard treatment in patients with limited-stage disease is radiotherapy combined with chemotherapy. In extensive SCLC, the importance of consolidation thoracic radiotherapy in patients with a good treatment response has become increasingly recognized. In both limited and extensive disease, prophylactic cranial irradiation is recommended in patients who respond to treatment. New therapeutic approaches such as immunotherapy are being increasingly incorporated into the treatment of SCLC, although more slowly than in non-small cell lung cancer (NSCLC)...

Lung cancer continues to be the most common cause of cancer death. Screening programs for high risk patients with the use of low-dose computed tomography (CT) has led to the identification of small lung lesions that were difficult to identify using previous imaging modalities. Electromagnetic navigational bronchoscopy (ENB) is a novel technique that has shown to be of great utility during the evaluation of small, peripheral lesions, that would otherwise be challenging to evaluate with conventional bronchoscopy...

Opiates are still the most effective and widely used treatments for acute and chronic pain. However, the problems associated with morphine and other standard opioid analgesics severely limit their effectiveness in the clinic. PPL-101 and PPL-103 derived from morphine and morphinan ring systems contain a chiral N-substituent, which confers it with a unique combination of high-binding affinities and partial agonist activities at mu, delta, and kappa opioid receptors, leading to unique in vivo pharmacology compared to other conventional opioids...

BACKGROUND Levetiracetam is an antiepileptic drug frequently used in critically ill patients. Levetiracetam is primarily eliminated as a parent compound via glomerular filtration and requires dose adjustment in renal insufficiency, but the literature on patients receiving continuous veno-venous hemofiltration (CVVH) is scant.
