Transcranial Doppler to gauge postreperfusion remedy subsequent severe ischemic stroke: The literature assessment.
The Affordable Care Act (ACA) included financial and regulatory incentives and goals for states to bolster their health insurance rate review programs, increase their anticipated loss ratio requirements, expand Medicaid, and establish state-based exchanges. We grouped states by political party control and compared their reactions across these policy goals. To identify changes in states' rate review programs and anticipated loss ratio requirements in the individual and small group markets since the ACA's enactment, we conducted legal research and contacted each state's insurance regulator. We linked rate review program changes to the Centers for Medicare and Medicaid Services' (CMS) criteria for an effective rate review program. We found, of states that did not meet CMS's criteria when the ACA was enacted, most made changes to meet those criteria, including Republican-controlled states, which generally oppose the ACA. This finding is likely the result of the relatively low administrative burden associated with reviewing health insurance rates and the fact that doing so prevents federal intervention in rate review. However, Republican-controlled states were less likely than non-Republican-controlled states to increase their anticipated loss ratio requirements to align with the federal retrospective medical loss ratio requirement, expand Medicaid, and establish state-based exchanges, because of their general opposition to the ACA. We conclude that federal incentives for states to strengthen their health insurance rate review programs were more effective than the incentives for states to adopt other insurance-related policy goals of the ACA.Personal beliefs of medical students may interfere with their tendency for learning Complementary and Alternative Medicine concepts. This study aimed to investigate the knowledge and attitudes of medical students toward complementary and alternative medicine in Urmia, Iran. A structured questionnaire was used as data collection instrument. One hundred questionnaires were returned. Thirty-one percent of students reported use of alternative medicine for at least once. Iranian Traditional Medicine was the main type of alternative medicine used by medical students (93.5%). Neuromuscular disorders were the main indication of alternative medicine use among students (34.4%). Ninety percent of participants demonstrated competent knowledge about acupuncture while the lowest scores belonged to homeopathy (12%). Study results showed that 49% of medical students had positive attitudes and demonstrated a willingness to receive training on the subject. Thus, there appears a necessity to integrate complementary and alternative medicine into the medical curriculum, by taking expectations and feedbacks of medical students into consideration.
Phosphoglycerate kinase (PGK) deficiency is an X-linked neurometabolic genetic disorder with variable systemic manifestations. So far, only one patient with retinal anomalies has been reported, but no visual electrophysiology findings were described. We report the first description of visual electrophysiology in a child with PGK deficiency. This provides further information for the site of involvement in the eye.

A case history of a nine-year-old boy with PGK deficiency is reported.

This patient was diagnosed with PGK deficiency by screening soon after birth, as his mother was a known carrier of a PGK gene mutation. A bone marrow transplant was performed at the age of 9 months. He had two episodes of encephalopathy following the transplant but no acute episode of haemolysis. From the age of 6 years, his vision has been deteriorating. Visual electrophysiology results identified retinal involvement involving both rod and cone dysfunction. The visual evoked potential was normal.

Retinal dystrophy may be one of the clinical manifestations of phosphoglycerate kinase deficiency.

The theory of Depth of Processing (Craik and Lockhart in J Verbal Learning Verbal Behav 11671-684, 1972) discusses the varying degrees of strengths of memory traces as the result of differential levels of processing on the retrieved input. Additionally, they claim that there are three levels of visual, auditory and semantic processes applied on the stimuli in the short-term memory leading to discrepancy in the durability of the memory traces and the later ease of recall and retrieval. In the present article, it is tried to demonstrate if there are evidences of more durable memory traces formed after semantic, visual and auditory processions of the incoming language data in two groups of (a) children in their language learning critical age and (b) youngsters who have passed the critical age period. The comparisons of the results made using two-way ANOVAs revealed the superiority of semantic processing for both age groups in recall, retention and consequently recognition of the new English vocabularies by EFL learners.The elderly constitute a sizeable proportion of the acute coronary syndrome (ACS) population, and this population is continually increasing in number. Guideline-directed therapy is frequently underutilized in the elderly due to concerns about patient safety.

This paper reviews current literature in the context of contemporary American and European guidance.Identification of new psychoactive substances (NPS) is challenging. Developing targeted methods for their analysis can be difficult and costly due to their impermanence on the drug scene. Accurate-mass mass spectrometry (AMMS) using a quadrupole time-of-flight (QTOF) analyzer can be useful for wide-scope screening since it provides sensitive, full-spectrum MS data. Our article presents a qualitative screening workflow based on data-independent acquisition mode (all-ions MS/MS) on liquid chromatography (LC) coupled to QTOFMS for the detection and identification of NPS in biological matrices. The workflow combines and structures fundamentals of target and suspect screening data processing techniques in a structured algorithm. This allows the detection and tentative identification of NPS and their metabolites. We have applied the workflow to two actual case studies involving drug intoxications where we detected and confirmed the parent compounds ketamine, 25B-NBOMe, 25C-NBOMe, and several predicted phase I and II metabolites not previously reported in urine and serum samples. The screening workflow demonstrates the added value for the detection and identification of NPS in biological matrices.Postmortem redistribution (PMR) is one of numerous problems in postmortem toxicology making correct interpretation of measured drug concentrations difficult or even impossible. Time-dependent PMR in peripheral blood and especially in tissue samples is still under-explored. For further investigation, an easy applicable method for the simultaneous quantitation of over 80 forensically relevant compounds in 11 different postmortem matrices should be developed and validated overcoming the challenges of high inter-matrix and intra-matrix concentration variances. Biopsy samples (20 mg) or body fluids (20 μL) were spiked with an analyte mix and deuterated internal standards, extracted by liquid-liquid extraction, and analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS). For highest applicability, an easy solvent calibration was used. Furthermore, time-consuming dilution of high concentration samples showing detector saturation was circumvented by two overlapping calibration curves using (12)C isotope monitoring for low concentrations and (13)C isotopes for high concentration, respectively. The method was validated according to international guidelines with modifications. Matrix effects and extraction efficiency were strongly matrix and analyte dependent. In general, brain and adipose tissue produced the highest matrix effects, whereas cerebrospinal fluid showed the least matrix effects. Accuracy and precision results were rather matrix independent with some exceptions. Despite using an external solvent calibration, the accuracy requirements were fulfilled for 66 to 81 % of the 83 analytes. Depending on the matrix, 75-93 % of the analytes showed intra-day precisions at less then 20 %. (12)C and (13)C calibrations gave comparable results and proved to be a useful tool in expanding the dynamic range.Here, we report on a proof-of-concept study highlighting a new approach for quantitative surface enhanced Raman spectroscopy (SERS) measurements. This has been achieved by implementing the standard addition method (SAM) within a lab-on-a-chip (LOC) system. The approach has been successfully tested to quantify congo red as a model analyte even in the presence of the chemically related molecule methyl red. Thus, the developed concept demonstrates its potential to quantify analytes via SERS in the presence of other SERS active molecules. Graphical Abstract Congo red was quantified by means of the standard addition method implemented in the lab-on-a-chip device. Due to the developed approach, a direct detection out of the sample and in the presence of an interfering substance was possible.Silver nanoparticles (AgNPs) are increasingly used in medical devices as innovative antibacterial agents, but no data are currently available on their chemical transformations and fate in vivo in the human body, particularly on their potential to reach the circulatory system. To study the processes involving AgNPs in human plasma and blood, we developed an analytical method based on hydrodynamic chromatography (HDC) coupled to inductively coupled plasma mass spectrometry (ICP-MS) in single-particle detection mode. An innovative algorithm was implemented to deconvolute the signals of dissolved Ag and AgNPs and to extrapolate a multiparametric characterization of the particles in the same chromatogram. From a single injection, the method provides the concentration of dissolved Ag and the distribution of AgNPs in terms of hydrodynamic diameter, mass-derived diameter, number and mass concentration. This analytical approach is robust and suitable to study quantitatively the dynamics and kinetics of AgNPs in complex biological fluids, including processes such as agglomeration, dissolution and formation of protein coronas. The method was applied to study the transformations of AgNP standards and an AgNP-coated dressing in human plasma, supported by micro X-ray fluorescence (μXRF) and micro X-ray absorption near-edge spectroscopy (μXANES) speciation analysis and imaging, and to investigate, for the first time, the possible presence of AgNPs in the blood of three burn patients treated with the same dressing. Together with our previous studies, the results strongly support the hypothesis that the systemic mobilization of the metal after topical administration of AgNPs is driven by their dissolution in situ. Graphical Abstract Simplified scheme of the combined analytical approach adopted for studying the chemical dynamics of AgNPs in human plasma/blood.
