    This study entailed a 3 (instructional intervention) × 2 (assessment-type) between-subjects experimental design employing a pretest-intervention-posttest methodology. The instructional interventions were administered between subjects in three conditions: (a) dynamic instruction, (b) triarchic or theory of successful intelligence-control instruction, and (c) standard-control instruction. The assessment-type consisted between subjects of either (a) a group-administered dynamic posttest or (b) the same group-administered posttest interspersed with a control filler activity. Performance in different mathematics content areas taught in fourth grade was investigated. In total, 1,332 students and 63 classroom teachers in 24 schools across six school districts participated in the study. The results indicate the advantages of using dynamic instruction and assessment in regular classrooms while teaching mathematics, especially when the student body is highly ethnically diverse.

  4. Kinetics for exchange of imino protons in the d(C-G-C-G-A-A-T-T-C-G-C-G) double helix and in two similar helices that contain a G . T base pair, d(C-G-T-G-A-A-T-T-C-G-C-G), and an extra adenine, d(C-G-C-A-G-A-A-T-T-C-G-C-G).

    The relaxation lifetimes of imino protons from individual base pairs were measured in (I) a perfect helix, d(C-G-C-G-A-A-T-T-C-G-C-G), (II) this helix with a G . C base pair replaced with a G . T base pair, d(C-G-T-G-A-A-T-T-C-G-C-G), and (III) the perfect helix with an extra adenine base in a mismatch, d(C-G-C-A-G-A-A-T-T-C-G-C-G). The lifetimes were measured by saturation recovery proton nuclear magnetic resonance experiments performed on the imino protons of these duplexes. The measured lifetimes of the imino protons were shown to correspond to chemical exchange lifetimes at higher temperatures and spin-lattice relaxation times at lower temperatures. Comparison of the lifetimes in these duplexes showed that the destabilizing effect of the G . T base pair in II affected the opening rate of only the nearest-neighbor base pairs. For helix III, the extra adenine affected the opening rates of all the base pairs in the helix and thus was a larger perturbation for opening of the base pairs than the G . T base pair. The temperature dependence of the exchange rates of the imino proton in the perfect helix gives values of 14-15 kcal/mol for activation energies of A . T imino protons. These relaxation rates were shown to correspond to exchange involving individual base pair opening in this helix, which means that one base-paired imino proton can exchange independent of the others. For the other two helices that contain perturbations, much larger activation energies for exchange of the imino protons were found, indicating that a cooperative transition involving exchange of at least several base pairs was the exchange mechanism of the imino protons. The effects of a perturbation in a helix on the exchange rates and the mechanisms for exchange of imino protons from oligonucleotide helices are discussed.

    Full Text Available Abstract Background Internet administered cognitive behaviour therapy (CBT is a promising new way to deliver psychological treatment, but its effectiveness in regular care settings and in relation to more traditional CBT group treatment has not yet been determined. The primary aim of this study was to compare the effectiveness of Internet-and group administered CBT for panic disorder (with or without agoraphobia in a randomised trial within a regular psychiatric care setting. The second aim of the study was to establish the cost-effectiveness of these interventions. Methods Patients referred for treatment by their physician, or self-referred, were telephone-screened by a psychiatric nurse. Patients fulfilling screening criteria underwent an in-person structured clinical interview carried out by a psychiatrist. A total of 113 consecutive patients were then randomly assigned to 10 weeks of either guided Internet delivered CBT (n = 53 or group CBT (n = 60. After treatment, and at a 6-month follow-up, patients were again assessed by the psychiatrist, blind to treatment condition. Results Immediately after randomization 9 patients dropped out, leaving 104 patients who started treatment. Patients in both treatment conditions showed significant improvement on the main outcome measure, the Panic Disorder Severity Scale (PDSS after treatment. For the Internet treatment the within-group effect size (pre-post on the PDSS was Cohen's d = 1.73, and for the group treatment it was d = 1.63. Between group effect sizes were low and treatment effects were maintained at 6-months follow-up. We found no statistically significant differences between the two treatment conditions using a mixed models approach to account for missing data. Group CBT utilised considerably more therapist time than did Internet CBT. Defining effect as proportion of PDSS responders, the cost-effectiveness analysis concerning therapist time showed that Internet treatment had superior cost

    To consider the extent, nature, and range of risk arrangements between physician groups and health maintenance organizations (HMOs) for self-administered injectable (SAI) drugs; to examine types and frequencies of SAI drug-use management strategies adopted by physician groups; and to explore the relationship between locus and level of financial risk for SAIs and physician group strategy adoption. We used a multiple case-study design to select physician groups and their health maintenance organization (HMO) contractual partners in 4 markets in the United States (Northwest, Northeast, Midwest, Southwest). Physician groups in these markets were chosen based on size (e50 physicians) and experience with drug risk (e1 year). Physician groups were asked to identify their 3 major HMO contractual partners in each market. Telephone interviews were conducted from January 2000 to June 2001, with the resulting purposive sample of 37 individuals representing 20 physician groups. We found that the level and locus of SAI financial risk were related to the adoption of management strategies. Physician groups with higher financial risk for SAIs adopted more strategies than lower-risk groups. Groups with SAI financial risk in the medical services capitation (MSC) adopted 9.2 strategies per group. In contrast, groups with SAI financial risk in the pharmacy-risk budget (PRB) averaged 1.5 strategies per group. Groups with SAI financial risk in both the MSC and PRB fell in-between, averaging 4.5 strategies per group. The most frequently adopted strategy was designing evidenced-based therapeutic guidelines, i.e., protocols based on evidence from the peer-reviewed literature used to guide physicians in the treatment of typically chronic conditions (9 groups, 45% of sample). The second most common strategy involved adapting the existing utilization management system to process SAIs (7 groups, 35%) and the establishment of office procedures for internal authorization (5 groups, 25%).

    Anti-G is commonly present with anti-D and/or anti-C and can confuse serological investigations. in general, anti-G is not considered a likely cause of severe hemolytic disease of the fetus and newborn (HDFN), but it is important to differentiate it from anti-D in women who should be administered anti-D immunoglobulin prophylaxis. We report one woman with three pregnancies severely affected by anti-C+G requiring intrauterine treatment and a review of the literature. In our case, the identification of the correct antibody was delayed because the differentiation of anti-C+G and anti-D+C was not considered important during pregnancy since the father was D-. In addition, anti-C+G and anti-G titer levels were not found to be reliable as is generally considered in Rh immunization. Severe HDFN occurred at a maternal anti-C+G antibody titer of S and anti-G titer of 1 in comparison with the critical titer level of 16 or more in our laboratory. close collaboration between the immunohematology laboratory and the obstetric unit is essential. In previously affected families, early assessment for fetal anemia is required even when titers are low.

    To perform an audit to review and minimize the reasons of failure to administer Intrapartum antibiotic prophylaxis (IAP) to all GBS positive mothers who presented in labor and it?s effect on fetal outcome. Methodology: A review of all the electronic charts at Tawam Hospital during a 6 month period from 6th April till 6th October 2009. It included women who presented in labor with a GBS positive status who needed to receive IAP and their babies blood cultures were performed postnatal. Results: There were 2405 deliveries during this period. Two hundred and nine cases were GBS positive. IAP was given only to 48 patients i.e 23% while 161 (77%) did not receive any treatment. The various reasons documented were patient presented late in active labor were 59%. Medication (Penicillin) was ordered but delayed from pharmacy. Penicillin ordered late or not ordered by the doctor in 14% and 1% were the patients who underwent elective c-section. All the babies had no growth of GBS with blood culture postnatal. Conclusion: The various strategies to improve the rate of administration of IAP which have been discussed above including patient education, patient information leaflet, physician order from antenatal clinic and midwife ordering the IAP need to be addressed and implement a new guideline.

    2014-01-01

    C+G content (GC content or G+C content) is known to be correlated with genome/chromosome size in bacteria but the relationship for other kingdoms remains unclear. This study analyzed genome size, chromosome size, and base composition in most of the available sequenced genomes in various kingdoms. Genome size tends to increase during evolution in plants and animals, and the same is likely true for bacteria. The genomic C+G contents were found to vary greatly in microorganisms but were quite similar within each animal or plant subkingdom. In animals and plants, the C+G contents are ranked as follows: monocot plants>mammals>non-mammalian animals>dicot plants. The variation in C+G content between chromosomes within species is greater in animals than in plants. The correlation between average chromosome C+G content and chromosome length was found to be positive in Proteobacteria, Actinobacteria (but not in other analyzed bacterial phyla), Ascomycota fungi, and likely also in some plants; negative in some animals, insignificant in two protist phyla, and likely very weak in Archaea. Clearly, correlations between C+G content and chromosome size can be positive, negative, or not significant depending on the kingdoms/groups or species. Different phyla or species exhibit different patterns of correlation between chromosome-size and C+G content. Most chromosomes within a species have a similar pattern of variation in C+G content but outliers are common. The data presented in this study suggest that the C+G content is under genetic control by both trans- and cis- factors and that the correlation between C+G content and chromosome length can be positive, negative, or not significant in different phyla.

    The aim of the experiment was to evaluate effects of zinc gluconate (ZnGlu) and probiotic administration on the daily rhythm of cloacal temperature ( t cloacal ) in broiler chickens of different age groups during the hot-dry season. One-day-old broiler chicks ( n  = 60) were divided into groups I-IV of 15 chicks per group, and treated for 35 days: Group I (control) was given deionized water; Group II, ZnGlu (50 mg/kg); Group III, probiotic (4.125 × 10 6  cfu/100 mL), and Group IV, ZnGlu (50 mg/kg) + probiotic (4.125 × 10 6  cfu/100 mL). Air dry-bulb temperature ( t db ), relative humidity (RH), and temperature-humidity index (THI) inside the pen, and t cloacal of each broiler chick were obtained bihourly over a 24-h period; on days 21, 28, and 35 of the study. Values of t db (32.10 ± 0.49°C), RH (49.94 ± 1.91%), and THI (38.85 ± 0.42) obtained were outside the thermoneutral zone for broiler chickens, and suggested that the birds were subjected to heat stress. Application of the periodic model showed disruption of daily rhythm of t cloacal in broilers on day 21, which was synchronized by probiotic administration. The administration of probiotics or ZnGlu + probiotics to a greater extent decreased the mesor and amplitude, delayed the acrophases of t cloacal in broilers, especially at day 35, as compared to the controls. Overall, the t cloacal values in broiler chickens administered with probiotic alone (41.25 ± 0.05°C) and ZnGlu + probiotic (41.52 ± 0.05°C) were lower ( P  probiotic alone synchronized t cloacal of the birds at day 21, and, in addition, decreased t cloacal response most, followed by its coadministration with ZnGlu, the antioxidants may be beneficial in modulating daily rhythmicity of t cloacal and alleviating adverse effects of heat stress on broiler chickens during the hot-dry season. © 2017 The Authors.

    To assess the potential for sucralfate administered rectally to reduce the risk of late rectal morbidity in patients undergoing nonconformal radiotherapy (RT) for carcinoma of the prostate and to study the variables potentially contributing to late rectal morbidity and particularly to explore the relationship between acute and late toxicity. Eighty-six patients with localized prostate carcinoma were randomized in a double-blind, placebo-controlled study to a daily enema of 3 g of sucralfate in a 15-mL suspension or the same suspension without sucralfate. The enema began the first day of RT and was continued for 2 weeks after treatment completion. The primary end point of the study was acute Radiation Therapy Oncology Group (RTOG)/European Organization for Research and Treatment of Cancer (EORTC) toxicity; however, the patients were followed for an additional 5 years on a 6-month basis. The evaluation included late RTOG/EORTC toxicity and a patient self-assessment questionnaire. With a median follow-up of 5 years, the Kaplan-Meier probability of late Grade 2 RTOG/EORTC toxicity was 12% (95% confidence interval [CI] 2-22%) for placebo and 5% (95% CI 0-12%) for sucralfate (p = 0.26). The probability of late rectal bleeding was 59% (95% CI 45-73%) for placebo and 54% (95% CI 40-68%) for sucralfate. No statistically significant difference was found between the treatment arms for the peak incidence of any of the other patient self-assessment variables. Cox proportional hazards modeling indicated acute RTOG/EORTC toxicity of Grade 2 or greater was associated with a hazard ratio of 2.74 (95% CI 1.31-5.73) for the development of late toxicity of Grade 1 or greater. Substituting the patient self-assessment variables for acute RTOG/EORTC toxicity revealed that rectal pain of a moderate or severe grade during RT was the best predictor of the subsequent development of late toxicity, with a hazard ratio of 3.44 (95% CI 1.68-7). The results of this study do not support the use of

    Safety precautions for laboratory staff working with meningococci should primarily rely on laboratory procedures preventing exposure to aerosols containing viable meningococci. Despite this, vaccination is a key component of protection in the occupational setting. In the UK in 2009, there were no licensed vaccines for meningococcal capsular group B or conjugate vaccines for capsular groups A, C, W and Y. We therefore undertook a Phase II trial in laboratory workers to investigate the safety and immunogenicity of a four component group B vaccine (4CMenB) and a quadrivalent group A, C, W and Y conjugate vaccine (ACWY-CRM). Enrolment was open to staff aged 18-65 years at the Public Health Laboratory, Manchester who may have had a potential occupational exposure risk to meningococci. 4CMenB was administered at 0, 2 and 6 months in the non-dominant arm and ACWY-CRM concomitantly at 0 months in the dominant arm. Pre- and post-vaccination blood samples were taken and analysed by the serum bactericidal antibody (SBA) assay against A, C, W and Y strains and a panel of seven diverse group B strains. Diary cards were used to record any local and systemic reactions following each vaccination. In total, 38 staff were enrolled and received initial vaccinations with 31 completing the trial per protocol. Both vaccines were proven safe, with local reactogenicity being more commonly reported following 4CMenB than ACWY-CRM. High proportions of subjects had putative protective SBA titres pre-vaccination, with 61-84 and 61-87% protected against A, C, W and Y strains and diverse MenB strains, respectively. Post-vaccination, SBA titres increased with 95-100 and 90-100% of subjects with protective SBA titres against A, C, W and Y strains and diverse MenB strains, respectively. These data suggest that 4CMenB and ACWY-CRM are safe when administered concomitantly and have the potential to enhance protection for laboratory workers. www.clinicaltrials.gov identifier: NCT00962624.

    Hemoglobin (Hb) is the protein responsible for oxygen transportation. It is a tetrameric protein comprising two α- and two β-globin subunits. In the literature, a large number of mutations in the α- and β-globin genes have been documented. Among these mutations, Hb Presbyterian (HBB: c.327 C>G), is a naturally occurring mutant exerting low oxygen affinity. The C to G exchange (AAC>AAG) at codon 108 of the β-globin gene results in the substitution of asparagine by lysine. Here, we document the identification of HBB: c.327 C>G in a 6-year-old female patient and her father from Nicaragua and Cuba, respectively. The presence of the abnormal Hb was confirmed by cellulose acetate electrophoresis, high performance liquid chromatography (HPLC) and genomic DNA sequencing. The β-globin gene sequences for both, father and daughter, disclosed the heterozygous mutation at codon 108 to be Hb Presbyterian or HBB: c.327 C>G. The mutant Hb was previously reported in four families from North America, Germany, Japan and Spain, respectively. This is the fifth family carrying HBB: c.327 C>G described to date and the first report from Latin America.

    Full Text Available Aim: Defensins are cationic antimicrobial peptides expressed in epithelial cells. Such peptides exhibit antibacterial, antifungal and antiviral properties, and are a component of the innate immune response. It has been suggested that they have a protective role in the oral cavity. This study evaluated the DEFB1 polymorphism in diabetic patients with or without periodontitis in comparison to healthy controls. Material and Methods: We used Hairpin-Shaped Primer (HP assay to study the distribution of the -44 C/G SNP (rs1800972 in 119 human DNAs obtained from diabetic patients and healthy control patients. Results: The results indicate that there are no differences in distribution between groups and that in diabetic periodontitis patients the homozygous mutant could be found more frequently. Conclusion: Further studies are necessary in order to investigate the role of DEFB1 polymorphisms in diabetic periodontitis patients and the influence of the peptide in periodontal pathogens.

Analysis of the propagation of its signal throughout the small lobe indicated that the real part of the permittivity at 90 MHz is of (1.27±0.05). The first interpretation of this value using dielectric properties of mixtures of dust and ices (H2O, CO2), led to the conclusion that the comet porosity ranges between 75-85%. In addition, the dust/ice ratio was found to range between 0.4-2.6 and the permittivity of dust (including 30% of porosity) was determined to be lower than 2.9.The dust permittivity estimate is now reduced by taking into account the updated values of nucleus density and of dust/ice ratio, in order of providing further insights into the nature of the constituents of comet 67P/C-G [2]. We adopt a systematic approach: i) determination of the dust permittivity as a function of the ice (I) to dust (D) and vacuum (V) volume fraction; ii) comparison with the permittivity of meteoritic, mineral and organic materials from literature and laboratory measurements; iii) test of several composition models of the nucleus, corresponding to cosmochemical end members of 67P/C-G. For each of these models the location in the ternary I/D/V diagram is calculated based on available dielectric measurements, and confronted to the locus of 67P/C-G. The number of compliant models is small and the cosmochemical implications of each are discussed [2]. An important fraction of carbonaceous material is required in the dust in order to match CONSERT permittivity observations, establishing that comets represent a massive carbon reservoir.Support from Centre National d'Études Spatiales (CNES, France) for this work, based on observations with CONSERT on board Rosetta, is acknowledged. The CONSERT instrument was designed, built and operated by IPAG, LATMOS and MPS and was financially supported by CNES, CNRS, UJF/UGA, DLR and MPS

    The general purpose particle transport Monte Carlo code, MORSE-C.G., is implemented on a parallel computing transputer-based system having MIMD architecture. Example problems are solved which are representative of the 3-principal types of problem that can be solved by the original serial code, namely, fixed source, eigenvalue (k-eff) and time-dependent. The results from the parallelized version of the code are compared in tables with the serial code run on a mainframe serial computer, and with an independent, deterministic transport code. The performance of the parallel computer as the number of processors is varied is shown graphically. For the parallel strategy used, the loss of efficiency as the number of processors is increased, is investigated. (author)

    Full Text Available The main aim of this study is to present the results from a study of the relationship between personality types described by C. G. Jung and emotional intelligence. The investigated subjects were 150 at the age of 18 – 50. The methods of research were MBTI (Myers-Briggs Type Indicator - Bulgarian adaptation (Rusinova, 1992 and one psychological questionnaire measuring emotional intelligence -Bulgarian adaptation (Stoyanova, 2008. The received data indicated that the functions of thinking and sensing, and introversion correlated inversely with the factors of emotional intelligence “Sharing emotions and empathy”, “Motivation to overcome difficulties and optimisms” and extroversion correlated proportionally with them. The function feeling correlated proportionally with the factor “Sharing emotions and empathy” and it correlated inversely with the factor “Recognition of nonverbal expression of emotion of the other people”.

  8. C. G. Jung and intuition: from the mindscape of the paranormal to the heart of psychology.

    2018-02-01

    Intuition is central in the work, practice, and philosophical legacy of C. G. Jung. In this paper, I will first discuss the importance of intuition for Jung in the paradigm usually designated the 'paranormal'. Jung was attracted to intuition as an extra-ordinary gift or function in the traditional sense, and this is considered here in relation to his 1896-1899 Zofingia Lectures and 1902 On the Psychology and Pathology of So-called Occult Phenomena: A Psychiatric Study. A significant development then occurred in 1913, when esotericist intuitions were turned toward psychological use with Jung's Red Book. There, his personal and private use of intuition - and we know how extraordinarily intuitive he was - led Jung to fully incorporate intuition at the core of his psychology. Not only in his practice, in the crucial intuitive form of empathy, but as we will see, also at the very heart of his theory. In 1921, Jung wrote Psychological Types, where intuition became one - the first - of the four fundamental functions and types of the psyche next to thinking, feeling, and sensation. In 1921, Jung proved to the world in rational argument that intuition was no longer a psychologist's hobby for table turning, but the most significant function of the psyche. © 2018, The Society of Analytical Psychology.

    Full Text Available Elevated resistin levels and the polymorphisms located at gene encoding resistin (RETN are associated with diabetic pathogenesis. However, the correlation between RETN genotypes and T2DM is controversial due to discrepancies among reports. This study aimed at investigating and clarifying the putative association of RETN and T2DM in Taiwanese population. The resistin levels and RETN -420C>G genotypes in 244 control and 305 T2DM subjects were examined. Meanwhile, the association between genetic polymorphism of RETN -420C>G and resistin levels, as well as between RETN -420C>G and subjects’ clinical characteristics was statistically analyzed. The RETN -420C>G genotypes (p = 0.01 and G allele (p = 0.002 were significantly associated with T2DM. In addition, concanavalin A-stimulated peripheral blood mononuclear cells from T2DM subjects had higher resistin-secreting ability (p = 0.044. Nevertheless, no significant association between the subjects’ biochemical data and RETN -420 SNPs was found. Our results indicate that RETN -420C>G SNPs and G allele are significantly associated with T2DM. Investigation of RETN polymorphisms in T2DM patients from various ethnic populations are crucial and will contribute to the understanding of this gene in the diabetic etiology. The present results may contribute to gain knowledge on the complex genetic heterogeneity of type 2 diabetes.

    Full Text Available Abstract Background Several association studies have shown that -844 G/A and HindIII C/G PAI-1 polymorphisms are related with increase of PAI-1 levels, obesity, insulin resistance, glucose intolerance, hypertension and dyslipidemia, which are components of metabolic syndrome. The aim of this study was to analyze the allele and genotype frequencies of these polymorphisms in PAI-1 gene and its association with metabolic syndrome and its components in a sample of Mexican mestizo children. Methods This study included 100 children with an age range between 6-11 years divided in two groups: a 48 children diagnosed with metabolic syndrome and b 52 children metabolically healthy without any clinical and biochemical alteration. Metabolic syndrome was defined as the presence of three or more of the following criteria: fasting glucose levels ≥ 100 mg/dL, triglycerides ≥ 150 mg/dL, HDL-cholesterol th percentile, systolic blood pressure (SBP and diastolic blood pressure (DBP ≥ 95th percentile and insulin resistance HOMA-IR ≥ 2.4. The -844 G/A and HindIII C/G PAI-1 polymorphisms were analyzed by PCR-RFLP. Results For the -844 G/A polymorphism, the G/A genotype (OR = 2.79; 95% CI, 1.11-7.08; p = 0.015 and the A allele (OR = 2.2; 95% CI, 1.10-4.43; p = 0.015 were associated with metabolic syndrome. The -844 G/A and A/A genotypes were associated with increase in plasma triglycerides levels (OR = 2.6; 95% CI, 1.16 to 6.04; p = 0.02, decrease in plasma HDL-cholesterol levels (OR = 2.4; 95% CI, 1.06 to 5.42; p = 0.03 and obesity (OR = 2.6; 95% CI, 1.17-5.92; p = 0.01. The C/G and G/G genotypes of the HindIII C/G polymorphism contributed to a significant increase in plasma total cholesterol levels (179 vs. 165 mg/dL; p = 0.02 in comparison with C/C genotype. Conclusions The -844 G/A PAI-1 polymorphism is related with the risk of developing metabolic syndrome, obesity and atherogenic dyslipidemia, and the HindIII C/G PAI-1 polymorphism was associated with the

    1994-04-12

    The antiparallel purine.purine.pyrimidine DNA triplex, RRY6, which contains a T.C.G inverted triplet in the center of the sequence, was examined by proton and phosphorous two-dimensional NMR spectroscopy. The local conformation of the T.C.G triplet (T4.C11.G18) and the effect of this triplet on the global helical structure were analyzed in detail. The formation of the T.C.G triplet is confirmed by a set of cross-strand NOEs, including unusual cross-strand NOEs between the third strand and the pyrimidine strand as opposed to the purine strand of the duplex. NMR data suggest that the T.C.G triplet may be present in an equilibrium between a non-hydrogen-bonded form and a T(O4)-C(NH2) hydrogen-bonded form and that there is a distortion of the in-plane alignment of the three bases. The flanking G.G.C base triplets are well-defined on the 5'-side of T4, but somewhat interrupted on the 3'-side of T4. The effect of the third strand binding on the Watson-Crick duplex was probed by an NMR study of the free duplex RY6. NMR parameters are affected mostly around the T.C.G inversion site. The perturbations extend to at least two adjacent base triplets on either side. The binding of the third purine strand and the accommodation of a central T.C.G inversion in RRY6 does not require a readjustment in sugar pucker, which remains in the range of C2'-endo. 31P resonances of RRY6 distribute over a range of 2.2 ppm. The H-P coupling patterns of the third strand differ from those of the duplex. General spectral patterns defined by the marker protons of the RRY and YRY triplexes are compared.

    To evaluate the effectiveness of an immunization training program for pharmacy technicians on technicians' self-reported confidence, knowledge, and number of vaccines administered. A one-group pre- and posttest study was conducted with certified pharmacy technicians from Albertsons and Safeway community pharmacies in Idaho. Thirty pharmacy technicians were recruited to participate in an immunization administration training program comprising a 2-hour home study and a 2-hour live training. Pharmacy technician scores on a 10-question knowledge assessment, responses on a pre- and posttraining survey, and number of immunizations administered in the 6-month period following the training were collected. Twenty-five pharmacy technicians completed the home study and live portions of the immunization training program. All 29 pharmacy technicians who took the home study assessment passed with greater than 70% competency on the first attempt. Technicians self-reported increased confidence with immunization skills between the pretraining survey and the posttraining survey. From December 2016 to May 2017, the technicians administered 953 immunizations with 0 adverse events reported. For the first time, pharmacy technicians have legally administered immunizations in the United States. Trained pharmacy technicians demonstrated knowledge of vaccination procedures and self-reported improved confidence in immunization skills and administered immunizations after participating in a 4-hour training program.

    Concomitant administration of bivalent rLP2086 (Trumenba [Pfizer, Inc] and diphtheria, tetanus, and acellular pertussis and inactivated poliovirus vaccine (DTaP/IPV) was immunologically noninferior to DTaP/IPV and saline and was safe and well tolerated. Bivalent rLP2086 elicited robust and broad bactericidal antibody responses to diverse Neisseria meningitidis serogroup B strains expressing antigens heterologous to vaccine antigens after 2 and 3 vaccinations. Bivalent rLP2086, a Neisseria meningitidis serogroup B (MnB) vaccine (Trumenba [Pfizer, Inc]) recently approved in the United States to prevent invasive MnB disease in individuals aged 10-25 years, contains recombinant subfamily A and B factor H binding proteins (fHBPs). This study evaluated the coadministration of Repevax (diphtheria, tetanus, and acellular pertussis and inactivated poliovirus vaccine [DTaP/IPV]) (Sanofi Pasteur MSD, Ltd) and bivalent rLP2086. Healthy adolescents aged ≥11 to B proteins different from the vaccine antigens. Participants were randomly assigned to receive bivalent rLP2086 + DTaP/IPV (n = 373) or saline + DTaP/IPV (n = 376). Immune responses to DTaP/IPV in participants who received bivalent rLP2086 + DTaP/IPV were noninferior to those in participants who received saline + DTaP/IPV.The proportions of bivalent rLP2086 + DTaP/IPV recipients with prespecified seroprotective hSBA titers to the 4 MnB test strains were 55.5%-97.3% after vaccination 2 and 81.5%-100% after vaccination 3. The administration of bivalent rLP2086 was well tolerated and resulted in few serious adverse events. Immune responses to DTaP/IPV administered with bivalent rLP2086 to adolescents were noninferior to DTaP/IPV administered alone. Bivalent rLP2086 was well tolerated and elicited substantial and broad bactericidal responses to diverse MnB strains in a high proportion of recipients after 2 vaccinations, and these responses were further enhanced after 3 vaccinations.ClinicalTrials.gov identifier NCT01323270

    A 5-day-old girl was referred to our clinic for evaluation of congenital malformations. She was identified with a pathogenic mutation c.758C>G (p.Pro253Arg) in FGFR2 gene using targeted exome sequencing. The de novo mutation was confirmed with Sanger sequencing in the patient and her parents. She showed occipital plagiocephaly with frontal bossing (Figure A and B). Skull frontal and lateral radiography revealed fusion of most of the sutures except coronal suture, with convolutional markings (Figure D and E). She had complete cleft palate (Figure C). Her fused bilateral hands showed type II syndactyly with complete syndactyly between the ring and the little fingers (Figure F1-F3). Both toes were simple syndactyly with side-to-side fusion of skin (Figure G1-)

    In 193 cases autopsied between 1945 and 1980, all persons who had been intravascularly injected with Thorotrast in life, the authors found 131 malignant hepatic tumors, 20 liver cirrhoses, 6 myeloid leukemias, 4 erythroleukemias, 5 aplastic anemias, 4 lung cancers, 1 mesothelioma and 1 osteosarcoma. The causes of death in the Thorotrast-administered autopsy group (193 cases) were compared with those of a non-Thorotrast-administered autopsy group (95,000 cases) of the same sex and age at death as recorded in the Annals of Japanese Pathological Autopsy cases from 1958 to 1978. This comparison revealed that the frequencies of malignant hepatic tumors, liver cirrhosis, erythroleukemia, and aplastic anemia were significantly higher in the Thorotrast-administered group than in the non-Thorotrast-administered group.

  20. A novel complex A/C/G intergenotypic recombinant of hepatitis B virus isolated in southern China.

    Directory of Open Access Journals (Sweden)

    Heling Su

    Full Text Available Hepatitis B virus (HBV genotypes and subgenotypes may vary in geographical distribution and virological features. Previous investigations, including ours, showed that HBV genotypes B and C were respectively predominant in South and North China, while genotypes A and D were infrequently detected and genotype G was not found. In this study, a novel A/C/G intergenotype was identified in patients with chronic HBV infection in Guilin, a city in southern China. Initial phylogenetic analysis based on the S gene suggested the HBV recombinant to be genotype G. However, extended genotyping based on the entire HBV genome indicated it to be an A/C/G intergenotype with a closer relation to genotype C. Breakpoint analysis using the SIMPLOT program revealed that the recombinant had a recombination with a arrangement of genotypes A, G, A and C fragments. Compared with the HBV recombinants harboring one or two genotype G fragments found in Asian countries, this Guilin recombinant was highly similar to the Vietnam (98-99% and Long An recombinants (96-99%, but had a relatively low similarity to the Thailand one (89%. Unlike those with the typical genotype G of HBV, the patients with the Guilin recombinant were seropositive for HBeAg. Moreover, a relatively high HBV DNA viral load (>2 × 10(6 IU/ml was detected in the patients, and the analysis of viral replication capacity showed that the Guilin recombinant strains had a competent replication capacity similar to genotypes B and C strains. These findings can aid in not only the clarification of the phylogenetic origin of the HBV recombinants with the genotype G fragment found in Asian countries, but also the understanding of the virological properties of these complicated HBV recombinants.

    : Hemophilia A is a bleeding disorder caused by coagulation factor VIII protein deficiency or dysfunction, which is classified into severe, moderate, and mild according to factor clotting activity. An overwhelming majority of missense and nonsense mutations occur in exons of F8 gene, whereas mutations in introns can also be pathogenic. This study aimed to investigate the effect of an intronic mutation, c.6430-3C>G (IVS22-3C>G), on pre-mRNA splicing of the F8 gene. We applied DNA and cDNA sequencing in a Chinese boy with hemophilia A to search if any pathogenic mutation in the F8 gene. Functional analysis was performed to investigate the effect of an intronic mutation at the transcriptional level. Human Splicing Finder and PyMol were also used to predict its effect. We found the mutation c.6430-3C>G (IVS22-3C>G) in the F8 gene in the affected boy, with his mother being a carrier. cDNA from the mother and pSPL3 splicing assay showed that the mutation IVS22-3C>G results in a two-nucleotide AG inclusion at the 3' end of intron 22 and leads to a truncated coagulation factor VIII protein, with partial loss of the C1 domain and complete loss of the C2 domain. The in-silico tool predicted that the mutation induces altered pre-mRNA splicing by using a cryptic acceptor site in intron 22. The IVS22-3C>G mutation was confirmed to affect pre-mRNA splicing and produce a truncated protein, which reduces the stability of binding between the F8 protein and von Willebrand factor carrier protein due to the loss of an interaction domain.

    Even when individuals with schizophrenia have an intact ability to enjoy rewarding moments, the means to assist them to translate rewarding experiences into goal-directed behaviors is unclear. The present study sought to determine whether informationally administered rewards enhance intrinsic motivation to foster goal-directed behaviors in individuals with schizophrenia (SZ) and healthy controls (HCs). Eighty-four participants (SZ=43, HCs=41) were randomly assigned to conditions involving either a performance-contingent reward with an informationally administered reward or a task-contingent reward with no feedback. Participants were asked to play two cognitive games of equalized difficulty. Accuracy, self-reported intrinsic motivation, free-choice intrinsic motivation (i.e., game play during a free-choice observation period), and perceived competency were measured. Intrinsic motivation and perceived competency in the cognitive games were similar between the two participant groups. The informationally administered reward significantly enhanced self-reported intrinsic motivation and perceived competency in both the groups. The likelihood that individuals with schizophrenia would play the game during the free-choice observation period was four times greater in the informationally administered reward condition than that in the no-feedback condition. Our findings suggest that, in the context of cognitive remediation, individuals with schizophrenia would benefit from informationally administered rewards. Copyright © 2017 Elsevier B.V.

    Binding of dsDNA by cyclic GMP-AMP (cGAMP) synthase (cGAS) triggers formation of the metazoan second messenger c[G(2',5')pA(3',5')p], which binds the signaling protein STING with subsequent activation of the interferon (IFN) pathway. We show that human hSTING(H232) adopts a "closed" conformation upon binding c[G(2',5')pA(3',5')p] and its linkage isomer c[G(2',5')pA(2',5')p], as does mouse mSting(R231) on binding c[G(2',5')pA(3',5')p], c[G(3',5')pA(3',5')p] and the antiviral agent DMXAA, leading to similar "closed" conformations. Comparing hSTING to mSting, 2',5'-linkage-containing cGAMP isomers were more specific triggers of the IFN pathway compared to the all-3',5'-linkage isomer. Guided by structural information, we identified a unique point mutation (S162A) placed within the cyclic-dinucleotide-binding site of hSTING that rendered it sensitive to the otherwise mouse-specific drug DMXAA, a conclusion validated by binding studies. Our structural and functional analysis highlights the unexpected versatility of STING in the recognition of natural and synthetic ligands within a small-molecule pocket created by the dimerization of STING.

    The causes of death of 144 Japanese autopsy cases during 1945-1975, who had been intravascularly injected with Thorotrast in life, were compared with those of non-Thorotrast-administered autopsy cases in the same age bracket, recorded in the Annals of Japanese Pathological Autopsy Cases during 1958-1973. This comparison revealed that the incidence of malignant hepatic tumors was more than 10 times higher in the Thorotrast-administered cases. The increase was attributable to an increased incidence of hemangioendothelioma and cholangiocarcinoma of the liver. The only significant increase of liver cirrhosis found to exist in the Thorotrast group occurred in the female cases. Some of the Thorotrast-administered cases were found to have developed myeloid leukemia and erythroleukemia. There was also a significant increase in the number of cases of aplastic anemia in the Thorotrast group, but clinically and pathologically these were atypical. Lymphatic leukemia was not observed. No significant difference was found in the incidence of either malignant lymphomas or osteosarcomas in the Thorotrast group and the controls. Lung cancer, on the other hand, showed a significantly higher incidence among the controls than among the Thorotrast-administered cases

    A previously derived projection operator method is applied to the calculation of the cross section for 12 C+ 12 C→ 12 C(0 + 2 )+ 12 C(g.s.) with a breathing mode model being used to describe the 0 + 2 (7.68 MeV) state of 12 C. The relationship to processes leading to alpha particle channels is discussed. The cross section for 12 C+ 12 C→ 12 C(3 - )+ 12 C(g.s.) is also calculated and possible correlations with inelastic scattering to the 0 + 2 and 2 + states of 12 C are discussed. The results for both 0 + 2 and 3 - inelastic scattering are in reasonable agreement with experiment

    Objective: To study the prevalence of HBV, HCV, HGV infections in patients on hemodialysis (HD). Methods: Serum HBsAg, HBsAb, HBeAg, HBeAb, HBcAb, antibody against HCV, antibody against HGV (with ELISA), HBV-DNA, HCV-RNA (with RT-PCR) were detected in 68 patients on HD and 30 controls. Results: The positive rates of hepatitis virus infections in patients on HD was significantly higher than those in controls. All the HCV (n=21) and HGV (n=12) infections were in the HD group. Among the HD patients, those with history of transfusion (n=32) had significantly higher infected rates than the patients without transfusion (n=36) (P<0.01 for all the three infections). Conclusion: There was high incidence of hepatits virus infections patients on hemodialysis, especially with hepatitis C and G virus infections. Main causes involved were: administration of blood and blood products plus cross-infection through dialysis apparatus. More strict antiseptic and isolation technique should be implemented. (authors)

    Several studies have evaluated the association of miR-146a C/G with head and neck cancer (HNC) susceptibility, and overall cancer risk, but with inconclusive outcomes. To drive a more precise estimation, we carried out this meta-analysis. The literature was searched from MEDLINE (mainly PubMed), Embase, the Cochrane Library, and Google Scholar databases to identify eligible studies. A total of 89 studies were included. The results showed that miR-146a C/G was significantly associated with increased HNC risk in dominant model ( I 2 =15.6%, P heterogeneity =0.282, odds ratio (OR) =1.088, 95% confidence interval (CI) =1.002-1.182, P =0.044). However, no cancer risk was detected under all genetic models. By further stratified analysis, we found that rs4919510 mutation contributed to the risk of HNC amongst Asians under homozygote model ( I 2 =0, P heterogeneity =0.541, OR =1.189, 95% CI =1.025-1.378, P =0.022), and dominant model ( I 2 =0, P heterogeneity =0.959, OR =1.155, 95% CI =1.016-1.312, P =0.028). Simultaneously, in the stratified analysis by source of controls, a significantly increased cancer risk amongst population-based studies was found under homozygote model, dominant model, recessive model, and allele comparison model. However, no significant association was found in the stratified analysis by ethnicity and source of control. The results indicated that miR-146a C/G polymorphism may contribute to the increased HNC susceptibility and could be a promising target to forecast cancer risk for clinical practice. However, no significant association was found in subgroup analysis by ethnicity and source of control. To further confirm these results, well-designed large-scale case-control studies are needed in the future. © 2018 The Author(s).

  19. A revolution of the mind: some implications of George Hogenson's 'The Baldwin Effect: a neglected influence on C.G. Jung's evolutionary thinking' (2001).

    George Hogenson's 2001 paper 'The Baldwin Effect: a neglected influence on C.G. Jung's evolutionary thinking' developed the radical argument that, if archetypes are emergent, they 'do not exist in the sense that there is no place that the archetypes can be said to be'. In this paper, I show how Hogenson's thinking has been seminal to my own: it is not just archetypes but the mind itself that has no 'place'. The mind is a dynamic system, emergent from the cultural environment of symbolic meanings to which humans are evolutionarily adapted. Drawing on the work of philosopher John Searle, I argue that symbols constitute the realities that they bring forth, including the imaginal realities of the psyche. The implications for clinical work include a rejection of structural models of the psyche in favour of the emergence of symbolic realities in the context of psychoanalysis as a distributed system of cognition. © 2015, The Society of Analytical Psychology.

  20. Association between the HTR2C rs1414334 C/G gene polymorphism and the development of the metabolic syndrome in patients treated with atypical antipsychotics

    Full Text Available Few studies have assessed the association between the rs1414334 C/G polymorphism in the HTR2C gene and the development of the metabolic syndrome in patients treated with atypical antipsychotics. To provide further evidence, a cross-sectional study was conducted in Spain between 2012 and 2013 in 166 patients with these characteristics. In these patients, the association between the polymorphism and the presence of the metabolic syndrome was determined by implementing binary logistic regression models adjusted for variables associated with the metabolic syndrome. We did not confirm previous claims that the C allele of the polymorphism was linked to the metabolic syndrome: the association was in the opposite direction and non-significant. This conclusion held after taking gender and lifestyle variables into account.

    Clozapine is still considered the gold standard for treatment-resistant schizophrenia patients; however, up to 40% of patients do not respond adequately. Identifying potential predictors of clinical response to this last-line antipsychotic could represent an important goal for treatment. Among these, functional polymorphisms involved in dopamine system modulation, known to be disrupted in schizophrenia, may play a role. We examined the COMT Val158Met polymorphism, which plays a key role in dopamine regulation at the prefrontal level, and the 5-HT1A-R -1019 C/G polymorphism, a target of clozapine activity involved in the interaction between the serotonin and dopamine systems. 107 neuroleptic-refractory, biologically unrelated Italian patients (70 males and 37 females) with a DSM-IV diagnosis of schizophrenia who were being treated with clozapine were recruited. Psychopathology was assessed by the Positive and Negative Symptoms Scale (PANSS) at the beginning of treatment, and at weeks 8 and 12. Genomic DNA was extracted from venous blood samples. COMT rs4680 (Val158Met) and 5-HT1A-R rs6295 (-1019 C/G) polymorphisms were analyzed by PCR-based restriction fragment length and direct sequencing, respectively. We found a significant effect of COMT and 5-HT1A-R on the PANSS Negative Subscale variation, with greater improvement among COMT Val/Val and 5-HT1A-R G/G subjects. The findings support the hypothesis that COMT rs4680 and 5-HT1A-R rs6295 polymorphisms could influence the negative symptom response to clozapine, probably through modulation of the dopaminergic system.

  3. Tumour targeting with systemically administered bacteria.

    LENUS (Irish Health Repository)

    Morrissey, David

    2012-01-31

    Challenges for oncology practitioners and researchers include specific treatment and detection of tumours. The ideal anti-cancer therapy would selectively eradicate tumour cells, whilst minimising side effects to normal tissue. Bacteria have emerged as biological gene vectors with natural tumour specificity, capable of homing to tumours and replicating locally to high levels when systemically administered. This property enables targeting of both the primary tumour and secondary metastases. In the case of invasive pathogenic species, this targeting strategy can be used to deliver genes intracellularly for tumour cell expression, while non-invasive species transformed with plasmids suitable for bacterial expression of heterologous genes can secrete therapeutic proteins locally within the tumour environment (cell therapy approach). Many bacterial genera have been demonstrated to localise to and replicate to high levels within tumour tissue when intravenously (IV) administered in rodent models and reporter gene tagging of bacteria has permitted real-time visualisation of this phenomenon. Live imaging of tumour colonising bacteria also presents diagnostic potential for this approach. The nature of tumour selective bacterial colonisation appears to be tumour origin- and bacterial species- independent. While originally a correlation was drawn between anaerobic bacterial colonisation and the hypoxic nature of solid tumours, it is recently becoming apparent that other elements of the unique microenvironment within solid tumours, including aberrant neovasculature and local immune suppression, may be responsible. Here, we consider the pre-clinical data supporting the use of bacteria as a tumour-targeting tool, recent advances in the area, and future work required to develop it into a beneficial clinical tool.

  4. The T -786C, G894T, and Intron 4 VNTR (4a/b) Polymorphisms of the Endothelial Nitric Oxide Synthase Gene in Prostate Cancer Cases.

    In previously conducted some studies it has been revealed that nitric oxide (NO) and nitric oxide synthase (NOS) system play a significant role in carcinogenesis. Nitric oxide (NO) is regulated by endothelial nitric oxide synthase (eNOS) enzyme which is one of the isoenzymes of NO synthase (NOS). In this study we have tried to come to a conclusion about whether eNOS gene T -786C, G894T and Intron 4 VNTR (4a/b) polymorphisms might be considered as a risk factor causing prostate cancer (PCa) or not. A total of 200 subjects were included in this research. 84 patients with PCa (mean age 70.0 ± 6.4) and 116 healthy controls (mean age 69.9 ± 7.5) were recruited in this case-control study. Genomic DNA was extracted using the QIAamp DNA Blood Mini Kit (QIAGEN GmbH, Maryland, USA), according to the manufacturer's guidelines. The T-786C, G894T and Intron 4 VNTR (4a/b) polymorphisms were amplified using polymerase chain reation (PCR), detected by restriction fragment length polymorphism (RFLP). For T -786C polymorphism CC genotype [odds ratio (OR): 0.34, 95% confidence interval (CI): 0.15-0.78, P = 0.009)] and allele frequency (OR: 0.631, CI: 0.421-0.946, P = 0.026) is significant for control. In patients with PCa eNOS G894T polymorphism, both GT (OR: 0.069, CI: 0.027-0.174; P = 0.0001) and TT (OR: 0.040, CI: 0.013-0.123; P = = 0.0001) genotype distribution, and also T allele frequency (OR: 0.237, CI: 0.155-0.362, P = 0.0001) were considered significant statistically. While genotype distribution for the other polymorphism eNOS, intron 4 VNTR (4a/b), is insignificant statistically, "a" allele frequency was found out to be significant (OR: 2.223, CI: 1.311-3.769, P = 0.003). In this study we indicated that genotype and allele frequencies of eNOS T -786C and G894T polymorphisms are statistically significant in patients with PCa. eNOS T -786C and G894T polymorphisms may be associated with PCa susceptibility in the Turkish population. In contrast, intron 4 VNTR (4a

    The authors have identified eight independent transversions at CpG in 290 consecutive families with hemophilia B. These eight transversions account for 16.3% of all independent transversions in the sample, yet the expected frequency of CpG transversions at random in the factor IX gene is only 2.6% (P<0.1). The aggregate data suggest that the two types of CpG transversions (G:C[yields]T:A and G:C[yields]C:G) possess similar mutation rates (24.8 [times] 10[sup [minus]10] and 20.6 [times] 10[sup [minus]10], respectively), which are about fivefold greater than the comparable rates for transversions at non-CpG dinucleotides. The enhancement of transversions at CpG suggest that the model by which mutations occur at CpG may need to be reevaluated. The relationship, if any, between deamination of 5-methyl cytosine and enhancement of transversions at CpG remains to be defined. 28 refs., 2 tabs.

    de Moura, Vicente

    2014-06-01

    This article presents the history of one until now unknown case of C.G. Jung: Maggy Reichstein. Born in Indonesia in 1894 in a very aristocratic family, she brought her sister to Zurich to be treated by Jung in 1919, and later she herself was in analysis with him. Jung used her case as example in his lecture in 1937 on the realities of practical psychotherapy, relating it to the process of transference and countertransference. Jung deepened his studies in Eastern psychology after a series of dreams she had, which culminated in the Yoga Kundalini Seminars. She was also the case presented in his article of 1951 on the concept of synchronicity. Jung wrote that her case, concerning synchronicity, remained unique in his experience. Jung also published some of her mandalas. He considered her able to understand his ideas in depth. Reichstein was for Jung an important case, which challenged and triggered his interests in different subjects. © 2014, The Society of Analytical Psychology.

    Maier, Christian

    2016-04-01

    This paper investigates the possible impact of C.G. Jung's Tavistock Lectures on Bion's concept of the living container. In the first part of the paper, the author offers clues pointing to such an essential impact, which can be found in text passages as well as in the facts of the Bion-Beckett case, up to and including Bion's first publication of 'The imaginary twin'. The author suggests that cryptomnesia is the result of repression targeting a highly cathected author's communication which functions like a deep interpretation for the recipient, whose new theory then is a return of the repressed content as well as a transformation of it. The second part of the paper investigates the fate of the assumed cryptomnesia. From this point of view Bion's concept of the container in itself appears to be the result of growth in the container-contained mode. Finally the author deals with the question whether cryptomnesia in psychoanalytical literature can frequently be seen as the result of psychic growth. © 2016, The Society of Analytical Psychology.

    We report the detection of hydrogen chloride, HCl, in diffuse molecular clouds on the line of sight toward the star-forming region W31C (G10.6-0.4). The J = 1-0 lines of the two stable HCl isotopologues, H{sup 35}Cl and H{sup 37}Cl, are observed using the 1b receiver of the Heterodyne Instrument for the Far-Infrared (HIFI) on board the Herschel Space Observatory. The HCl line is detected in absorption, over a wide range of velocities associated with diffuse clouds along the line of sight to W31C. The analysis of the absorption strength yields a total HCl column density of a few 10{sup 13} cm{sup -2}, implying that HCl accounts for {approx}0.6% of the total gas-phase chlorine, which exceeds the theoretical model predictions by a factor of {approx}6. This result is comparable to those obtained from the chemically related species H{sub 2}Cl{sup +} and HCl{sup +}, for which large column densities have also been reported on the same line of sight. The source of discrepancy between models and observations is still unknown; however, the detection of these Cl-bearing molecules provides key constraints for the chlorine chemistry in the diffuse gas.

  9. Haematological disorders in Thorotrast-administered patients in Japan

    Fifteen haematological disorders including ten leukaemia cases, one primary acquired sideroblastic anaemia and four aplastic anaemia cases were studied clinicopathologically in autopsies from patients who had been administered Thorotrast in Japan. The leukaemia group, the primary acquired sideroblastic anaemia and the aplastic anaemia cases after Thorotrast administration were considered to be mainly atypical, and it was speculated that damage induced by Thorotrast may affect the haemopoietic stem cell level and the haemopoietic microenvironment. Both dose rate and absorbed dose estimated in bone marrow, spleen and liver at autopsy showed no significant difference between the leukaemia group, primary acquired sideroblastic anaemia, aplastic anaemia and non-haematological disorders excluding the malignant hepatic tumours and liver cirrhosis.

    Grape composition, which affects the wine sensory qualities, depends on vine features (rootstock, scion, vine health) and vineyard management as much as environmental factors. Mapping soil at the vineyard scale, in particular, helps in optimizing the terroir expression of the wine. The terroir effect however varies year by year, depending on the interaction of several factors, such as climate and soil. Aim of this research work was to set up a methodology to delineate homogeneous harvest zones (HZ) in the vineyard and to evaluate the vintage effect in them. Four terroir macro-units suitable for premium Sangiovese wine, which is the main cultivar of Chianti D.O.C.G., were selected within a wide farm of Chianti Classico district (Siena, Central Italy). The selected macro-units are representative of the most common and suitable viticultural environments of the Chianti Classico D.O.C.G. and include: 1) hills of high altitude (450-500 m a.s.l.) on feldspathic sandstones, with shallow sandy soils; 2) hills of high altitude (400-500 m a.s.l.) on calcareous flysches, with stony, clayey and calcareous soils; 3) hills of moderate altitude (250-350 m a.s.l.) on Pliocene sandy marine deposits; 4) hills and fluvial terraces of moderate altitude (200-300 m a.s.l., 50-100 m above the present river valley) on ancient fluvial deposits. Each terroir macro-unit was surveyed by soil proximal sensing, to define two homogeneous zones (HZs) in terms of soil physics and hydrology. The proximal sensors used to map the HZs were: i) γ-ray spectrometer, to map the variability of soil surface in terms of parent material, texture and stoniness; ii) electromagnetic induction sensor (EMI) to determine the spatial variability of texture and soil moisture in the sub-surface horizons. Thus, the soil moisture of each HZ was monitored during spring shoot growth (beginning of April), berries veraison (end of July-beginning of August) and final ripening phase before harvest (September).

    We report a clinical update of the hemoglobin (Hb) variant [β27(B9)Ala→Gly; HBB: c.83C>G], named Hb Siirt, that was previously described as a silent variant in a 23-year-old Kurdish female. The patient was also a carrier of the codon 5 (-CT) (HBB: c.17_18delCT) frameshift mutation and of the ααα anti 3.7 triplication. Her initial moderate β-thalassemia intermedia (β-TI) phenotype worsened with time, causing the patient to become a transfusion-dependent subject at the age of ∼40 years. Subsequent molecular characterization of both parents revealed that the Hb Siirt variant was inherited by the mother, while the other two globin alterations (HBB: c.17_18delCT and ααα anti 3.7 triplication) were genetically transmitted by the father. The latter remained a carrier of a mild β-TI phenotype throughout his life, at least until the age of 65 years. We hypothesize that the worsened clinical conditions in the daughter were due to the additional, maternally inherited Hb Siirt variant. However, protein 3D conformational analysis did not seem to reveal substantial overall structural changes. Among the other three described variants [Hb Volga (HBB: c.83C>A), Hb Knossos (HBB: c.82 G>T), Hb Grange-Blanche (HBB: c.83C>T] that are due to nucleotide substitutions at codon 27 of the β-globin gene; only Hb Knossos causes a β + -thalassemia (β + -thal) phenotype.

    Injection of local anesthetic into the transversus abdominis plane (TAP block) decreases systemic morphine requirements after abdominal surgery. We compared intraoperative surgeon-administered TAP block (surgical TAP) to anesthesiologist-administered transcutaneous ultrasound-guided TAP block (conventional TAP) for post-cesarean analgesia. We hypothesized that surgical TAP blocks would take less time to perform than conventional TAP blocks. We performed a randomized trial, recruiting 41 women undergoing cesarean delivery under neuraxial anesthesia, assigning them to either surgical TAP block (n=20) or conventional TAP block (n=21). Time taken to perform the block was the primary outcome, while postoperative pain scores and 24-hour opioid requirements were secondary outcomes. Student's t-test was used to compare block time and Kruskal-Wallis test opioid consumption and pain-scores. Time taken to perform the block (2.4 vs 12.1 min, P consumption (P=0.17) and postoperative pain scores at 4, 8, 24 and 48 h were not significantly different between the groups. Surgical TAP blocks are feasible and less time consuming than conventional TAP blocks, while providing comparable analgesia after cesarean delivery. Copyright © 2018 Elsevier Ltd.

    Full Text Available Background Sedation in dentistry is a controversial topic given the variety of opinions regarding its safe practice. Aims This article evaluates the various techniques used to administer sedation in dentistry and specific methods practiced to form a recommendation for clinicians. Methods An extensive literature search was performed using PubMed, Medline, Google Scholar, Google, and local library resources. Results Most of the literature revealed a consensus that light sedation on low-risk American Society of Anesthesiologists (ASA groups, that is ASA I, and possibly II, is the safest method for sedation in a dental outpatient setting. Conclusion Formal training is essential to achieve the safe practice of sedation in dentistry or medicine. The appropriate setting for sedation should be determined as there is an increased risk outside the hospital setting. Patients should be adequately assessed and medication titrated appropriately, based on individual requirements.

    The safety of Aquaflor® (50% w/w florfenicol [FFC]) incorporated in feed then administered to tilapia for 20 days (2x the recommended duration) at 0, 15, 45, or 75 mg/kg body weight/day (0, 1, 3, or 5x the recommended dose of 15 mg FFC/kg BW/d) was investigated. Mortality, behavioral change, feed consumption, body size, and gross and microscopic lesions were determined. Estimated delivered doses were >96.9% of target. Three unscheduled mortalities occurred but were considered incidental since FFC-related findings were not identified. Feed consumption was only affected during the last 10 dosing days when the 45 and 75 mg/kg groups consumed only 62.5% and 55.3% of the feed offered, respectively. There were significant, dose-dependent reductions in body size in the FFC-dose groups relative to the controls. Treatment-related histopathological findings included increased severity of lamellar epithelial hyperplasia, increased incidence of lamellar adhesions, decreased incidence of lamellar telangiectasis in the gills, increased glycogen-type and lipid-type hepatocellular vacuolation in the liver, decreased lymphocytes, increased blast cells, and increased individual cell necrosis in the anterior kidney, and tubular epithelial degeneration and mineralization in the posterior kidney. These changes are likely to be of minimal clinical relevance, given the lack of mortality or morbidity observed. This study has shown that FFC, when administered in feed to tilapia at the recommended dose (15 mg FFC/kg BW/day) for 10 days would be well tolerated.

  16. The role of human cytochrome P4503A4 in biotransformation of tissue-specific derivatives of 7H-dibenzo[c,g]carbazole

    The environmental pollutant 7H-dibenzo[c,g]carbazole (DBC) and its derivative, 5,9-dimethylDBC (DiMeDBC), produced significant and dose-dependent levels of micronuclei followed by a substantial increase in the frequency of apoptotic cells in the V79MZh3A4 cell line stably expressing the human cytochrome P450 (hCYP) 3A4. In contrast, neither micronuclei nor apoptosis were found in cells exposed to the sarcomagenic carcinogen, N-methylDBC (N-MeDBC). A slight but significant level of gene mutations and DNA adducts detected in V79MZh3A4 cells treated with N-MeDBC, only at the highest concentration (30 μM), revealed that this sarcomagenic carcinogen was also metabolized by hCYP3A4. Surprisingly, DBC increased the frequency of 6-thioguanine resistant (6-TG r ) mutations only at the highest concentration (30 μM), while DiMeDBC failed to increase the frequency of these mutations. The resistance to 6-thioguanine is caused by the mutations in the hypoxanthine-guanine phosphoribosyltransferase (Hprt) gene. The molecular analysis of the coding region of Hprt gene showed a deletion of the entire exon 8 in DiMeDBC-induced 6-TG r mutants, while no changes in the nucleotide sequences were identified in 6-TG r mutants produced by DBC and N-MeDBC. Based on our results, we suggest that hCYP3A4 is involved in the metabolism of DBC and its tissue-specific derivatives. While hCYP3A4 probably plays an important role in biotransformation of the liver carcinogens, DBC and DiMeDBC, it might only have a marginal function in N-MeDBC metabolism. - Highlights: → DBC activation via CYP3A4 resulted in micronuclei, DNA adduct formation and mutations in V79MZh3A4 cells. → The CYP3A4-mediated DiMeDBC activation caused micronuclei followed by apoptosis in V79MZh3A4 cells. → The genotoxic effects produced by N-MeDBC in V79MZh3A4 cells were negligible. → The hCYP3A4 may play an important role in DBC and DiMeDBC metabolism. → The CYP3A4 might only have a marginal function in N

    Highlights: • Rats and mice orally administered with nicotine tartrate for total of 4 weeks. • No treatment-related death or whole body toxicity observed in any of the groups. • Urothelium showed simple hyperplasia in treated rats and mice. • No significant change in BrdU labeling index or SEM classification of urothelium. - Abstract: Tobacco smoking is a major risk factor for multiple human cancers including urinary bladder carcinoma. Tobacco smoke is a complex mixture containing chemicals that are known carcinogens in humans and/or animals. Aromatic amines a major class of DNA-reactive carcinogens in cigarette smoke, are not present at sufficiently high levels to fully explain the incidence of bladder cancer in cigarette smokers. Other agents in tobacco smoke could be excreted in urine and enhance the carcinogenic process by increasing urothelial cell proliferation. Nicotine is one such major component, as it has been shown to induce cell proliferation in multiple cell types in vitro. However, in vivo evidence specifically for the urothelium is lacking. We previously showed that cigarette smoke induces increased urothelial cell proliferation in mice. In the present study, urothelial proliferative and cytotoxic effects were examined after nicotine treatment in mice and rats. Nicotine hydrogen tartrate was administered in drinking water to rats (52 ppm nicotine) and mice (514 ppm nicotine) for 4 weeks and urothelial changes were evaluated. Histopathologically, 7/10 rats and 4/10 mice showed simple hyperplasia following nicotine treatment compared to none in the controls. Rats had an increased mean BrdU labeling index compared to controls, although it was not statistically significantly elevated in either species. Scanning electron microscopic visualization of the urothelium did not reveal significant cytotoxicity. These findings suggest that oral nicotine administration induced urothelial hyperplasia (increased cell proliferation), possibly due to a

    The extract of pineapple leaves (EPL) has anti-diabetic and anti-dyslipidemic effects and can be developed into a promising natural medicine. This study was conducted to evaluate EPL's effects on developmental parameters in order to provide evidence of its safety before potential medical use. Five groups were included: a negative control that was given distilled water daily, a positive control that was dosed 7 mg/kg cyclophosphamide (CP) every two days, and three groups that were respectively dosed 2.0, 1.0, and 0.5 g/kg EPL daily. Female rats were dosed during the organogenesis period of gestation days (GD) 7-17 and terminated on GD 20. A series of parameters were examined. Data revealed that CP significantly reduced maternal body weight gains, caused maternal organ weight alterations, reduced female fertility, disturbed fetal growth and development, and caused marked teratogenic effects on fetal appearances, skeleton and internal organs. Distilled water and the three high doses of EPL did not cause any of the aforementioned effects. This study concluded that orally administered EPL is safe to rats during embryonic development.

    Cystic Fibrosis is the most common recessive autosomal rare disease found in Caucasians. It is caused by mutations on the Cystic Fibrosis Transmembrane Conductance Regulator gene (CFTR) that encodes a protein located on the apical membrane of epithelial cells. c.3909C>G (p.Asn1303Lys, old nomenclature: N1303K) is one of the most common worldwide mutations. This mutation has been found at high frequencies in the Mediterranean countries with the highest frequency in the Lebanese population. Therefore, on the genetic level, we conducted a complete CFTR gene screening on c.3909C>G Lebanese patients. The complex allele c.[744-33GATT(6); 869+11C>T] was always associated with the c.3909C>G mutation in cis in the Lebanese population. In cellulo splicing studies, realized by hybrid minigene constructs, revealed no impact of the c.3909C>G mutation on the splicing process, whereas the associated complex allele induces minor exon skipping.

    We investigated whether the recommended phenobarbital loading dose of 15-20 mg/kg with maintenance of 3-4 mg/kg/day can safely be administered to very low birth weight preterm newborns with seizures. Twenty-four convulsive preterms of Phenobarbital was administered intravenously with a loading dose of 15 mg/kg in approximately 10-15 min. After 24 h, the maintenance dose of 3 mg/kg/day was administered as a single injection. Blood samples were obtained 2, 24, 48, 72, and 96 h after the phenobarbital loading dose was administered, immediately before the next phenobarbital dose was injected. None of the cases had plasma phenobarbital concentrations above the therapeutic upper limit of 40 μg/mL on the 2nd hour; one case (4.7%), on the 24th; 11 cases (45.8%), on the 48th; 15 cases (62.5%), on the 72nd; and 17 cases (70.8%), on the 96th hour. A negative correlation was detected between the serum concentrations of phenobarbital and gestational age on the 72th (p, 0.036; r, -0.608) and 96th hour (p, 0.043; r, -0.769). We suggest that particular attention should be done while administering phenobarbital in preterms, as blood levels of phenobarbital are higher than the reference ranges that those are often reached with the recommended doses in these groups of babies.

    Constitutional mismatch repair deficiency syndrome (CMMRD) is a rare autosomal recessive predisposition to colorectal polyposis and other malignancies, often childhood-onset, that is caused by biallelic inheritance of mutations in the same mismatch repair gene. Here, we describe a patient with a clinical diagnosis of CMMRD based on colorectal polyposis and young-onset endometrial cancer who was identified to have two alterations in trans in PMS2: one known pathogenic mutation (c.1831insA; p.Ile611Asnfs*2) and one novel variant of uncertain significance (c.505C>G; p.Arg169Glu), a missense alteration. We describe the clinical and molecular features in the patient harboring this novel alteration c.505C>G, who meets clinical criteria for CMMRD and exhibits molecular evidence supporting a diagnosis of CMMRD. Although experimental validation is needed to confirm its pathogenicity, PMS2 c.505C>G likely has functional consequences that contributes to our patient's phenotype based on the patient's clinical presentation, tumor studies, and bioinformatics analysis.

    Recently, it has been shown that mutations in the P2 promoter of the hepatocyte nuclear factor (HNF)-4 alpha gene (HNF4A) cause maturity-onset diabetes of the young (MODY), while single nucleotide polymorphisms in this locus are associated with type 2 diabetes. In this study, we examined 1,189 bp...... of the P2 promoter and the associated exon 1D of HNF4A for variations associated with diabetes in 114 patients with type 2 diabetes, 72 MODYX probands, and 85 women with previous gestational diabetes mellitus. A -192c/g mutation was found in five patients. We screened 1,587 diabetic subjects and 4......,812 glucose-tolerant subjects for the -192c/g mutation and identified 5 diabetic and 1 glucose-tolerant mutation carriers (P=0.004).

    Nakamura, Mototoshi; Koga, Sukehiko; Kondo, Takeshi

    1993-01-01

    A survey of 104 hospitals was conducted to determine the administered activity of radionuclides. Eighty-five hospitals responded, and reported a total of 119,614 examinations in one year. The examinations included: bone scintigraphy, 26.4%; thallium-201 ( 201 Tl) myocardial scintigraphy, 15.5%; gallium-67 ( 67 Ga) scintigraphy, 13.3%; N-isopropyl-p-[ 123 I] iodoamphetamine (IMP) brain perfusion scintigraphy, 7.0%. The administered activity was corrected by body weight only for children at more than 80% of the responding hospitals. The number of hospitals that reported over-administration of radionuclide varied according to the type of scintigraphy performed: bone, 76%; inflammatory ( 67 Ga), 93%; myocardial ( 201 Tl), 89.2%; brain (IMP), 8.5%. The administered activity of IMP was closer to the upper limits specified in the Recommendations on Standardization of Radionuclide Imaging by the Japan Radioisotope Association (1987), because IMP is very expensive and is supplied as single vials. The highest average effective dose was for myocardial scintigraphy, the second-highest for inflammatory scintigraphy, and the third-highest for bone scintigraphy. In 201 Tl and 67 Ga scintigraphy, the entire contents of the vial may be administered two days before the expiration date, because the ratio of (true patient administered activity) to (declared patient administered activity) is similar to the ratio of (radioactivity on the day of supply) to (radioactivity on the day of expiration). The factors that influence administered activity are through put, price of the radionuclide, and whether the radionuclide is sold as a single vial. In order to decrease the effective dose, it is necessary to establish a close cooperation between medical personnel, the makers of radiopharmaceuticals, and manufactures of gamma cameras. (author)

    Full Text Available The study was conducted to evaluate the effects of romifidine alone (50 µg/kg and a combination of romifidine (50 µg/kg and ketamine (2.5 mg/kg after intrathecal administration in goats. Ten adult goats of either sex weighing between 15 and 20 kg were randomly placed in 2 groups (groups I and II. The agents were administered at the lumbosacral subarachnoid space. Clinico-physiological parameters such as analgesia, motor incoordination, sedation, salivation, heart rate, respiratory rate, arterial pressure, central venous pressure and rectal temperature were studied. Other haematobiochemical parameters monitored were packed cell volume, haemoglobin, plasma proteins, glucose, urea and creatinine. The onset of analgesia was faster in group II (35.5 ±6.25 s compared to that of group I (5.2 ±0.54 min. Analgesia of the tail, perineum, hind limbs, flank and thorax was mild to moderate in group I, but complete analgesia of tail, perineum and hind limbs was recorded in group II. Motor incoordination was mild in group I and severe in group II. Significant reduction in heart rate (more pronounced in group I and respiratory rate (more pronounced in group II, and a significant increase in central venous pressure were recorded in both groups. Mean arterial pressure was reduced in both groups, but more markedly in group I. Sedation, electro-cardiogram, rectal temperature and haemato-biochemical parameters did not show significant differences between the 2 groups. The results of this study indicated a possible synergistic analgesic interaction between intrathecally administered romifidine and ketamine, without causing any marked systemic effects in goats.

    A 60-year-old man with a history of hepatic cirrhosis and cardiomyopathy underwent transoesophageal echocardiogram. He received mild sedation and topical lidocaine. During the recovery period the patient developed ataxia and diplopia for about 30 mins, a result of lidocaine toxicity. The patient was administered a commonly used local anaesthetic, a combination of 2% viscous lidocaine, 4% lidocaine gargle and 5% lidocaine ointment topically to the oropharnyx. The total dose was at least 280 mg. Oral lidocaine undergoes extensive first pass metabolism and its clearance is quite dependent on rates of liver blood flow as well as other factors. The patient's central nervous system symptoms were mild and transient but remind us that to avoid adverse side effects, orally administered drugs with fairly high hepatic extraction ratio given to patients with chronic liver disease need to be given in reduced dosages. Even 'Safe' medications need to be carefully administered.

    Full Text Available In this study the analgesic efficacy of the pure agonistic opioid morphine and the cyclo-oxygenase type-2-selective carprofen were compared since there is no previous specific comparative study for these two common analgesics. Forty-five bitches undergoing elective ovariohysterectomy were randomly assigned to one of three groups; receiving morphine 0.4 mg/kg bodyweight pre-operatively and 0.2 mg/kg every 4-6 hours thereafter (Morphine group, receiving a once-off carprofen 4 mg/kg injection (Carprofen group or receiving both morphine and carprofen (MorphCarp group. The dogs were premedicated with acepromazine 0.01 mg/kg and induced with either thiopentone 5-10 mg/kg or propofol 4-6 mg/kg. General anaesthesia was maintained with halothane in oxygen. The degree of pain was assessed over a 24-hour period under blinded conditions using a pain scale modified from the University of Melbourne pain scale and the Glasgow composite pain tool. Physiological parameters such as respiratory rate, pulse rate and body temperature were also assessed over the same time period. There was no significant difference in pain-scores and thus analgesia offered by the three analgesia protocols at any assessment point across the three groups, but there were differences within groups across time points. Baseline total pain-scores were lower than scores at all post-operative points within all three groups. Both morphine and carprofen provided good analgesia without any obvious adverse effects. This study indicates that at the dosages indicated above, carprofen administered on its own produces analgesia equal to that produced by morphine and that the two drugs administered together do not produce better analgesia than either drug administered on its own.

There was no significant difference in pain-scores and thus analgesia offered by the three analgesia protocols at any assessment point across the three groups, but there were differences within groups across time points. Baseline total pain-scores were lower than scores at all post-operative points within all three groups. Both morphine and carprofen provided good analgesia without any obvious adverse effects. This study indicates that at the dosages indicated above, carprofen administered on its own produces analgesia equal to that produced by morphine and that the two drugs administered together do not produce better analgesia than either drug administered on its own.

    We intravenously administered flomoxef sodium (FMOX) 0.5-3.5 hours before cataract surgery and measured the concentration of the agent in the aqueous humor to investigate its penetration into the aqueous humor and its efficacy in the prevention of postoperative endophthalmitis. 56 patients who underwent cataract surgery were enrolled in this study. They received 1 g FMOX via a 20-minute intravenous drip beginning 0.5-3.5 hours before the operation. Aqueous humor was aspirated from the anterior chamber and assayed for FMOX concentration using high-performance liquid chromatography. The mean intraoperative FMOX concentrations in the patients' aqueous humor were 0.79 +/- 0.24 microg/ml (administered 3.5 hours before surgery)--1.47 0.79 microg/ml (administered 1.5 hours before surgery). These concentrations administered 0.5-3.0 hours before surgery sufficiently exceeded the minimum inhibitory concentration (MIC) 90 values against Staphylococcus epidermidis, Staphylococcus aureus and Propionibacterium acnes, but did not achieve the MIC90 values against Enterococcus faecalis and Pseudomonas aeruginosa. The FMOX concentrations in the aqueous humor sampling were adequate to kill bacteria in vitro. This drug may be efficacious in the prevention of postoperative endophthalmitis in patients undergoing cataract surgery.

    To determine the pharmacokinetics of an orally administered dose of tramadol in domestic rabbits (Oryctolagus cuniculus). 6 healthy adult sexually intact female New Zealand White rabbits. Physical examinations and plasma biochemical analyses were performed to ensure rabbits were healthy prior to the experiment. Rabbits were anesthetized with isoflurane, and IV catheters were placed in a medial saphenous or jugular vein for collection of blood samples. One blood sample was collected before treatment with tramadol. Rabbits were allowed to recover from anesthesia a minimum of 1 hour before treatment. Then, tramadol (11 mg/kg, PO) was administered once, and blood samples were collected at various time points up to 360 minutes after administration. Blood samples were analyzed with high-performance liquid chromatography to determine plasma concentrations of tramadol and its major metabolite (O-desmethyltramadol). No adverse effects were detected after oral administration of tramadol to rabbits. Mean +/- SD half-life of tramadol after administration was 145.4 +/- 81.0 minutes; mean +/- SD maximum plasma concentration was 135.3 +/- 89.1 ng/mL. Although the dose of tramadol required to provide analgesia in rabbits is unknown, the dose administered in the study reported here did not reach a plasma concentration of tramadol or O-desmethyltramadol that would provide sufficient analgesia in humans for clinically acceptable periods. Many factors may influence absorption of orally administered tramadol in rabbits.

    The cost of implementing professionally-led psychosocial interventions has limited their integration into routine care. To enhance the translation of effective psychosocial interventions in routine care, a self-administered format is sometimes used. The meta-analysis examined the efficacy of written self-administered, psychosocial interventions to improve outcomes among individuals with a physical illness. Studies comparing a written self-administered intervention to a control group were identified through electronic databases searching. Pooled effect sizes were calculated across follow-up time points using random-effects models. Studies were also categorised according to three levels of guidance (self-administered, minimal contact, or guided) to examine the effect of this variable on outcomes. Forty manuscripts were retained for the descriptive review and 28 for the meta-analysis. Findings were significant for anxiety, depression, distress, and self-efficacy. Results were not significant for quality of life and related domains as well as coping. Purely self-administered interventions were efficacious for depression, distress, and self-efficacy; only guided interventions had an impact on anxiety. Findings showed that written self-administered interventions show promise across a number of outcomes. Self-administered interventions are a potentially efficacious and cost-effective approach to address some of the most common needs of patients with a physical illness. Copyright © 2017 Elsevier B.V.

    2015-01-01

    Ectrodactyly – ectodermal dysplasia and cleft lip/palate (EEC) syndrome (OMIM 604292) is a rare disorder determined by mutations in the TP63 gene. Most cases of EEC syndrome are associated to mutations in the DNA binding domain (DBD) region of the p63 protein. Here we report on a three-generation Brazilian family with three individuals (mother, son and grandfather) affected by EEC syndrome, determined by a novel mutation c.1037C > G (p.Ala346Gly). The disorder in this family exhibits a broad spectrum of phenotypes: two individuals were personally examined, one presenting the complete constellation of EEC syndrome manifestations and the other presenting an intermediate phenotype; the third affected, a deceased individual not examined personally and referred to by his daughter, exhibited only the split-hand/foot malformation (SHFM). Our findings contribute to elucidate the complex phenotype-genotype correlations in EEC syndrome and other related TP63-mutation syndromes. The possibility of the mutation c.1037C > G being related both to acro-dermato-ungual-lacrimal-tooth (ADULT) syndrome and SHFM is also raised by the findings here reported. PMID:25983622

    Full Text Available Abstract Background In primary care, it is often difficult to diagnose cervical myelopathy. However, a delay in treatment could cause irreversible aftereffects. With a brief and effective self-administered questionnaire for cervical myelopathy, cervical myelopathy may be screened more easily and oversight may be avoided. As there is presently no screening tool for cervical myelopathy, the aim of this study was to develop a self-administered questionnaire for the screening of cervical myelopathy. Methods A case-control study was performed with the following two groups at our university hospital from February 2006 to September 2008. Sixty-two patients (48 men, 14 women with cervical myelopathy who underwent operative treatment were included in the myelopathy group. In the control group, 49 patients (20 men, 29 women with symptoms that could be distinguished from those of cervical myelopathy, such as numbness, pain in the upper extremities, and manual clumsiness, were included. The underlying conditions were diagnosed as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, tarsal tunnel syndrome, diabetes mellitus neuropathy, cervical radiculopathy, and neuralgic amyotrophy. Twenty items for a questionnaire in this study were chosen from the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire, which is a new self-administered questionnaire, as an outcome measure for patients with cervical myelopathy. Data were analyzed by univariate analysis using the chi-square test and by multiple logistic regression analysis. According to the resulting odds ratio, β-coefficients, and p value, items were chosen and assigned a score. Results Eight items were chosen by univariate and multiple logistic regression analyses and assigned a score. The Hosmer-Lemeshow statistic showed p = 0.805. The area under the receiver operation characteristic curve was 0.86. The developed questionnaire had a sensitivity of 93.5% and a

    We assessed the effect of milrinone application timing after reperfusion against myocardial stunning as compared with levosimendan in swine. Furthermore, we examined the role of p38 mitogen-activated protein kinase (p38 MAPK) in the milrinone-induced cardioprotection. All swine were subjected to 12-minutes ischemia followed by 90-minutes reperfusion to generate stunned myocardium. Milrinone or levosimendan was administered intravenously either for 20 minutes starting just after reperfusion or for 70 minutes starting 20 minutes after reperfusion. In another group, SB203580, a selective p38 MAPK inhibitor, was administered with and without milrinone. Regional myocardial contractility was assessed by percent segment shortening (%SS). Milrinone starting just after reperfusion, but not starting 20 minutes after reperfusion, improved %SS at 30, 60, and 90 minutes after reperfusion compared with that in the control group. SB203580 abolished the beneficial effect of milrinone. On the other hand, levosimendan starting 20 minutes after reperfusion, but not for 20 minutes starting just after reperfusion, improved %SS at 60 and 90 minutes after reperfusion. Milrinone should be administered just after reperfusion to protect myocardial stunning through p38 MAPK, whereas levosimendan improvement of contractile function could be mainly dependent on its positive inotropic effect.

    BACKGROUND: Management of pain in the pre-hospital setting is often inadequate. In 2011, ambulance personnel were authorized to administer intravenous fentanyl in the Central Denmark Region. The aim of this study was to evaluate the efficacy and safety of intravenous fentanyl administered...... by ambulance personnel. METHODS: Pre-hospital medical charts from 2348 adults treated with intravenous fentanyl by ambulance personnel during a 6-month period were reviewed. The primary outcome was the change in pain intensity on a numeric rating scale (NRS) from before fentanyl treatment to hospital arrival...... patients (1.3%) and hypotension observed in 71 patients (3.0%). CONCLUSION: Intravenous fentanyl caused clinically meaningful pain reduction in most patients and was safe in the hands of ambulance personnel.

    Introduction: In our region Advanced Emergency Medical Technicians (AEMTs) respond to acutely ill or injured patients in rural areas. The AEMTs have been authorized to administer fentanyl intravenously in doses up to 2 μg/kg to selected groups of patients in pain. Higher doses can be allowed...... by a physician after a teleconference. We examined the effect of intravenous (IV) fentanyl treatment, expressed as pain reduction on a 10-point Numeric Rating Scale (NRS). Moreover we examined the occurrence of negative coincident events to assess whether it was safe to let non-medical staff administer potent...... opioids intravenously.   Methods: Retrospectively we collected the case sheets for all patients treated with IV fentanyl by the AEMTs in 2005 and 2006. We excluded all patients where a physician had been directly involved in the prehospital treatment. We recorded the IV fentanyl dose, NRS-score before...

    The present research is focused on the optimization of administered radionuclide activity in renal studies using 9 9mTc-DMSA. The patients sample included 35 subjects, 23 of them were children and the other 12 were adults. Physical and metabolic characteristics of patients, total time of the study as well as radiopharmaceuticals quality and gamma camera performance was considered in the experiments. Image quality of each study was evaluated using subjective criteria from two expert observers, without previous information about administered activity, and objective criteria based on signal/noise ratios and variance of the random noise in the images. They were used to develop clustering and discriminant analysis over the independent variables to detect groups of images with differentiated quality from the physical and mathematical point of view. As a conclusion, we found that it is possible to reduce the given activities in 50%. (Author) 30 refs.

    Iron overload is associated with acquired and genetic conditions, the most common being hereditary hemochromatosis (HH) type-I, caused by HFE mutations. Here, we conducted a hospital-based case-control study of 41 patients from the São Miguel Island (Azores, Portugal), six belonging to a family with HH type-I pseudodominant inheritance, and 35 unrelated individuals fulfilling the biochemical criteria of iron overload compatible with HH type-I. For this purpose, we analyzed the most common HFE mutations- c.845G>A [p.Cys282Tyr], c.187C>G [p.His63Asp], and c.193A>T [p.Ser65Cys]. Results revealed that the family's HH pseudodominant pattern is due to consanguineous marriage of HFE-c.845G>A carriers, and to marriage with a genetically unrelated spouse that is a -c.187G carrier. Regarding unrelated patients, six were homozygous for c.845A, and three were c.845A/c.187G compound heterozygous. We then performed sequencing of HFE exons 2, 4, 5 and their intron-flanking regions. No other mutations were observed, but we identified the -c.340+4C [IVS2+4C] splice variant in 26 (74.3%) patients. Functionally, the c.340+4C may generate alternative splicing by HFE exon 2 skipping and consequently, a protein missing the α1-domain essential for HFE/ transferrin receptor-1 interactions. Finally, we investigated HFE mutations configuration with iron overload by determining haplotypes and genotypic profiles. Results evidenced that carriers of HFE-c.187G allele also carry -c.340+4C, suggesting in-cis configuration. This data is corroborated by the association analysis where carriers of the complex allele HFE-c.[187C>G;340+4T>C] have an increased iron overload risk (RR = 2.08, 95% CI = 1.40-2.94, poverload because they will produce two altered proteins--the p.63Asp [c.187G], and the protein lacking 88 amino acids encoded by exon 2. In summary, we provide evidence that the complex allele HFE-c.[187C>G;340+4T>C] has a role, as genetic predisposition factor, on iron overload in the S

    The purpose of this work was to collect the main information from the literature about the biotyping of Cryptococcus neoformans. The more up-to date research concerning the epidemiology of cryptococcosis comprising quite a few articles, mainly after the advent of AIDS, was also reviewed. The Cryptococcus neoformans varieties neoformans and gattii are well defined biochemically nowadays chiefly through the C.G.B. medium, according to Kwon-Chung et al. (1982). The isolation of C. neoformans var. gattii from flowers and leaves of Eucalyptus camaldulensis and Eucalyptus tereticornis, specially in Australia, through the works of Ellis & Pfeiffer (1990) and Pfeiffer & Ellis (1992) permitted very interesting epidemiological investigations on C. neoformans, a capsulated yeast by which Sanfelice, in Italy (1894; 1895) attracted attention of medical class. Busse, in 1894, described the first human case of cryptococcosis under the presentation of a bone lesion simulating sarcoma. In this paper, the Brazilian researchers focused on this subject were pointed out, followed by the Author's experience with the C.G.B. medium (L-canavanine, glycine and bromothymol blue) proposed by Kwon-Chung et al. (1982) with very good results. It was possible with such medium the study of 50 C.N.S. liquor samples, being 39 from AIDS patients (78%) and 11 from non-AIDS ones (22%). Thirty-seven out of the 39 HIV-positive patients (74%) were identified as C. neoformans var. gattii. From the negative HIV, 8 (16%) were classified as C. neoformans var. neoformans and 3 (6%) as C. neoformans var. gattii. We could not perform the serotyping of the above referred samples. It is evident anyway that in Brazil there exist both varieties gattii and neoformans, agents of neurocryptococcosis, including AIDS patients. The importance of neurocryptococcosis, mainly among AIDS patients, is stressed here, showing once more the value of C.G.B. medium in the typing of C. neoformans in its two varieties. Also, it is of

    Objective: The author describes the therapeutic effect of recombinant human interleukin-11 (rhIL-11) administered at different times on acute radiation sickness in monkeys. Methods: Rhesus monkeys irradiated with 3.0 Gy 60 Co γ rays were divided into 3 groups. One group was the control administered with vehicle, the second one was subjected to administer rhIL-11 on days 0-13 after TBI (60 μg·kg -1 ·d -1 , sc) and the third one to administer rhIL-11 on days 13-26 after TBI at the same doses. Results: The early treated group had higher platelet nadirs compared with that of the other two. The duration of platelet and leukocyte numbers below 50% of their baseline values shortened significantly in animals treated with rhIL-11, especially in the early treated group. During the first week after irradiation, the early treated group had lower erythrocyte count compared with the control, but it began to rise at day 19 after irradiation. Semi-solid bone marrow cell culture demonstrated that rhIL-11 could stimulate bone marrow cells to form more CFU-MK, CFU-Mix, CFU-E, BFU-E and CFU-GM in vitro. The authors also got the same results in histopathological observation. Conclusion: rhIL-11 administered at different times can not only accelerate the haematopoietic recovery of acute radiation sickness in rhesus monkeys, but also result in better therapeutic effect when administered earlier

    Maintenance of effective drug concentrations is essential for adequate treatment of epilepsy. Some antiepileptic drugs can be successfully administered rectally when the oral route of administration is temporarily unavailable. Oxcarbazepine is a newer antiepileptic drug that is rapidly converted to a monohydroxy derivative, the active compound. This study aimed to characterise the bioavailability, metabolism and tolerability of rectally administered oxcarbazepine suspension using a randomised, crossover design in ten healthy volunteers. Two subjects received 300 mg doses of oxcarbazepine suspension via rectal and oral routes and eight received 450 mg doses. A washout period of at least 2 weeks elapsed between doses. The rectal dose was diluted 1:1 with water. Blood samples and urine were collected for 72 hours post-dose. Adverse effects were assessed at each blood collection time-point using a self-administered questionnaire. Plasma was assayed for oxcarbazepine and monohydroxy derivative; urine was assayed for monohydroxy derivative and monohydroxy derivative-glucuronide. Maximum plasma concentration (C(max)) and time to reach C(max) (t(max)) were obtained directly from the plasma concentration-time curves. The areas under the concentration-time curve (AUCs) were determined via non-compartmental analysis. Relative bioavailability was calculated and the C(max) and AUCs were compared using Wilcoxon signed-rank tests. Mean relative bioavailability calculated from plasma AUCs was 8.3% (SD 5.5%) for the monohydroxy derivative and 10.8% (SD 7.3%) for oxcarbazepine. Oxcarbazepine and monohydroxy derivative C(max) and AUC values were significantly lower following rectal administration (p effects were headache and fatigue with no discernible differences between routes. Monohydroxy derivative bioavailability following rectal administration of oxcarbazepine suspension is significantly lower than following oral administration, most likely because of poor oxcarbazepine water

    The 2 antidotes for acute cyanide poisoning in the United States must be administered by intravenous injection. In the out-of-hospital setting, intravenous injection is not practical, particularly for mass casualties, and intramuscular injection would be preferred. The purpose of this study is to determine whether sodium nitrite and sodium thiosulfate are effective cyanide antidotes when administered by intramuscular injection. We used a randomized, nonblinded, parallel-group study design in 3 mammalian models: cyanide gas inhalation in mice, with treatment postexposure; intravenous sodium cyanide infusion in rabbits, with severe hypotension as the trigger for treatment; and intravenous potassium cyanide infusion in pigs, with apnea as the trigger for treatment. The drugs were administered by intramuscular injection, and all 3 models were lethal in the absence of therapy. We found that sodium nitrite and sodium thiosulfate individually rescued 100% of the mice, and that the combination of the 2 drugs rescued 73% of the rabbits and 80% of the pigs. In all 3 species, survival in treated animals was significantly better than in control animals (log rank test, Pcyanide poisoning in 3 clinically relevant animal models of out-of-hospital emergency care.

    Adult immunization rates worldwide fall below desired targets. Pharmacists are highly accessible healthcare providers with the potential to increase immunization rates among adults by administering vaccines in their practice setting. To determine the attitudes of community-based Canadian pharmacists with respect to expanding their scope of practice to include administration of immunizations. An internet-based survey was emailed to community pharmacists across Canada. The survey was piloted through focus groups for qualitative feedback, tested for content validity, and test-retest reliability prior to dissemination. There were 495 responses to the survey. The majority (88 %) agreed that pharmacists as immunizers would increase public access, improve rates (84 %), and be acceptable to the public (72 %). However, only 68 % agreed that pharmacists should be permitted to immunize. The majority of respondents (90 %) agreed that certification in vaccine administration should be required for pharmacists to administer vaccines. Pharmacists identified education, reimbursement, and negative interactions with other providers as barriers to pharmacists administering vaccines. Canadian pharmacists are willing to expand their scope of practice to include immunization. However, implementation requires professional development and certification in vaccine administration.

    The liquid wax obtained from the seeds of the arid-land shrub jojoba (Simmondsia chinensis) is finding increasing use in skin treatment preparations. The fate of this wax upon reaching the digestive tract was studied. 14C-Labeled wax was administered intragastrically to mice, and the distribution of the label in the body was determined as a function of time. Most of the wax was excreted, but a small amount was absorbed, as was indicated by the distribution of label in the internal organs and the epididymal fat. The label was incorporated into the body lipids and was found to diminish with time.

    Chlorpyrifos is a widely used organophosphate insecticide for domestic, agricultural and industrial purposes. Lead is a toxic heavy metal and it is used for domestic and industrial purposes. Taurine is a semi essential amino acid with bioprotective properties. The aim of this study was to investigate the effects of taurine on thyroid function in Wistar rats co-administered with chlorpyrifos and lead. The rats were divided into 5 groups of 10 rats each. The first two groups were administered with distilled water and soya oil (1 ml/kg) respectively. The other groups received taurine (50 mg/kg), chlorpyrifos + lead [chlorpyrifos (4.25 mg/kg, 1/20 median lethal dose] and lead (233.25 mg/kg, 1/20 median lethal dose) and taurine + chlorpyrifos + lead respectively. The treatments were administered once daily by oral gavage for 16 weeks. The rats were euthanized after the completion of the study and the thyroid function and thyroid histoarchitecture were evaluated. The results revealed that co-administration of chlorpyrifos and lead to the rats induced perturbations in thyroid function and this was manifested by reductions in the concentrations of triiodothyronine and thyroxine, increased thyroid stimulating hormone concentration and degeneration of the follicular epithelia of the thyroid gland. Taurine alleviated the perturbations in thyroid function and improved thyroid gland histoarchitecture. The beneficial effects of taurine may be attributed to its ability to protect the body from toxicity and oxidative stress. Taurine may be useful for prophylaxis against disruptions in thyroid function in animals that are exposed to environmental chlorpyrifos and lead.

    Mixed micelles, with their main constituents lecithin and glycocholic acid, form a new principle for the parenteral administration of compounds which are poorly water-soluble. Their composition of mainly physiological substances as well as their comparatively good stability substantiate their attractivity in comparison to existing solvents. A decomposition due to physical influences such as heat or storage for several years will almost exclusively affect the lecithin component in the form of hydrolysis into free fatty acids and lysolecithin. Their toxicity was examined experimentally in various studies using both undecomposed and artificially decomposed mixed micelles. In these studies the mixed micelles were locally and systemically well tolerated and proved to be neither embryotoxic, teratogenic nor mutagenic. Only when comparatively high doses of the undecomposed mixed micelles were administered, corresponding to approximately 30 to 50 times the anticipated clinical injection volume (of e.g. diazepam mixed micelles), did some vomitus (dogs), slight liver enzyme elevation (rats and dogs), and slightly increased liver weights (dogs) occur. After repeated injections of the artificially decomposed formulation (approximately 25% of lecithin hydrolyzed to free fatty acids and lysolecithin) effects such as intravascular haemolysis, liver enzyme elevations and intrahepatic cholestasis (dogs only) were observed but only when doses exceeding a threshold of approximately 40 to 60 mg lysolecithin/kg body weight were administered. All alterations were reversible after cessation of treatment.

    (/sup 3/H)-Palmitate labeled natural lamb surfactant and free (/sup 14/C)-choline were mixed with the lung fluid of 11 term lambs at cesarean section, before the first breath. After receiving the isotope, the lambs were delivered, allowed to breathe spontaneously, and were subsequently sacrificed from 5 min to 96 h of age. Alveolar washes, lung homogenates, microsomal and lamellar body fractions of lungs, and pulmonary alveolar macrophages were examined for the presence of labeled phosphatidylcholine. Analysis of the labeled natural surfactant kinetic data revealed an apparent t 1/2 of phosphatidylcholine in the whole lung of 6.0 days. This half-life can be interpreted only as a rough estimate. Appearance of considerable (/sup 3/H) labeled phosphatidylcholine in the lung homogenates demonstrated uptake of phosphatidylcholine from alveoli into lung tissue. The surfactant-associated label in homogenates was localized preferentially to lamellar body fractions. Some of the administered (/sup 14/C)-choline appeared in phosphatidylcholine. Almost all of this labeled phosphatidylcholine was associated with the homogenate. Extremely small % of administered (3H) and (14C) were found in pulmonary alveolar macrophages.

    The PET tracer, 124 I-cG250, directed against carbonic anhydrase IX (CAIX) shows promise for presurgical diagnosis of clear-cell renal cell carcinoma (ccRCC) (Divgi et al. in Lancet Oncol 8:304-310, 2007; Divgi et al. in J Clin Oncol 31:187-194, 2013). The radiometal 89 Zr, however, may offer advantages as a surrogate PET nuclide over 124 I in terms of greater tumor uptake and retention (Rice et al. in Semin Nucl Med 41:265-282, 2011). We have developed a nonlinear immunokinetic model to facilitate a quantitative comparison of absolute uptake and antibody turnover between 124 I-cG250 and 89 Zr-cG250 using a human ccRCC xenograft tumor model in mice. We believe that this unique model better relates quantitative imaging data to the salient biological features of tumor antibody-antigen binding and turnover. We conducted experiments with 89 Zr-cG250 and 124 I-cG250 using a human ccRCC cell line (SK-RC-38) to characterize the binding affinity and internalization kinetics of the two tracers in vitro. Serial PET imaging was performed in mice bearing subcutaneous ccRCC tumors to simultaneously detect and quantify time-dependent tumor uptake in vivo. Using the known specific activities of the two tracers, the equilibrium rates of antibody internalization and turnover in the tumors were derived from the PET images using nonlinear compartmental modeling. The two tracers demonstrated virtually identical tumor cell binding and internalization but showed markedly different retentions in vitro. Superior PET images were obtained using 89 Zr-cG250, owing to the more prolonged trapping of the radiolabel in the tumor and simultaneous washout from normal tissues. Estimates of cG250/CAIX complex turnover were 1.35 - 5.51 x 10 12 molecules per hour per gram of tumor (20 % of receptors internalized per hour), and the ratio of 124 I/ 89 Zr atoms released per unit time by tumor was 17.5.

    A survey of radiopharmaceutical activities used at the eight hospital centres specialising in paediatric nuclear medicine in Australia was conducted in 1999-2000 by the Australian and New Zealand Society of Nuclear Medicine and the Australasian Radiation Protection Society. Data on the maximum and minimum administered activities was obtained for 43 paediatric imaging procedures. The maximum values were significantly less than the corresponding Reference Activities for adults determined in a previous study. Activities for individual patients are calculated using surface area scaling at five centres and body weight scaling at three centres. The median values of A max and A min are recommended as Paediatric Reference Activities. The effective dose to patients of various sizes for the Paediatric Reference Activities and both methods of scaling was calculated for each procedure.

    To describe the changes in cardiac function after administration of three different solutions infused after anesthetic induction. Thirty-six patients scheduled for elective aortocoronary bypass surgery were randomly distributed into three groups. Over a period of 25 min after anesthetic induction, 12 received 10 ml/kg of Ringer solution (low dose crystalloid group), 12 received 20 ml/kg of Ringer solution (high dose crystalloid group), and 12 received 10 ml/kg of Ringer solution with 10 ml/kg of hydroxi-ethyl-almidon solution 450,000 D, 0.7 substitution grade (group C-HEA). Minute volume, systemic and pulmonary pressures, osmolality of blood and urine, and plasma and urine sodium concentrations were measured before and after infusion of the assigned liquid. In spite of the volume infused, low dose crystalloid group showed a high incidence of oliguria, increased urinary osmolality and decreased sodium in urine. Cardiac and systolic indices and left ventricular work load remained stable after infusion of the assigned liquid in low and high dose crystalloid groups, whereas they increased significantly ion group C-HEA (+23%, +16% and +20%). Administration of restricted doses of crystalloids after anesthetic induction favors the retention of water and sodium. Higher doses of crystalloids weaken this effect. However, neither of these two regimens leads to a more effective cardiac work load. A combination of crystalloids and colloids administered immediately after anesthetic induction temporarily improves cardiac performance during surgery.

  12. Opponent process properties of self-administered cocaine.

    Science.gov (United States)

    Ettenberg, Aaron

    2004-01-01

    Over the past decade, data collected in our laboratory have demonstrated that self-administered cocaine produces Opponent-Process-like behavioral effects. Animals running a straight alley once each day for IV cocaine develop over trials an approach-avoidance conflict about re-entering the goal box. This conflict behavior is characterized by a stop in forward locomotion (usually at the very mouth of the goal box) followed by a turn and 'retreat' back toward the goal box. The results of a series of studies conducted over the past decade collectively suggest that the behavioral ambivalence exemplified by rats running the alley for IV cocaine stems from concurrent and opponent positive (rewarding) and negative (anxiogenic) properties of the drug--both of which are associated with the goal box. These opponent properties of cocaine have been shown to result from temporally distinct affective states. Using a conditioned place preference test, we have been able to demonstrate that while the initial immediate effects of IV cocaine are reinforcing, the state present 15 min post-injection is aversive. In our most recent work, the co-administration of IV cocaine with either oral ethanol or IV heroin was found to greatly diminish the development and occurrence of retreat behaviors in the runway. It may therefore be that the high incidence of co-abuse of cocaine with either ethanol or heroin, stems from the users' motivation to alleviate some of the negative side effects of cocaine. It would seem then that the Opponent Process Theory has provided a useful conceptual framework for the study of the behavioral consequences of self-administered cocaine including the notion that both positive and negative reinforcement mechanisms are involved in the development and maintenance of cocaine abuse.

    Freund's complete adjuvant (FCA) is a commonly used immunopotentiator that can boost polyclonal antibody production in animal models such as rabbits, but FCA is also known to cause inflammation and pain. It is important to balance the welfare of animals with the goal of efficiently producing antibodies, but little is known about how common treatments for pain and inflammation, such as non-steroidal anti-inflammatory drugs (NSAIDs), affect the production of polyclonal antibodies. The purpose of this study was to measure polyclonal antibody production in rabbits that were administered FCA either with or without a concurrent treatment of a NSAID, carprofen. Rabbits were divided into two groups and were administered identical treatments of an antigen with adjuvant, and the treatment group also received carprofen injections at different stages of the study. Carprofen treatment did not significantly affect polyclonal antibody production, which suggests that carprofen and other NSAIDs can be used alongside FCA in rabbits to achieve desired levels of antibody production while minimizing pain and distress associated with the use of FCA.

    Full Text Available Fumonisins (FBs are mycotoxins produced by Fusarium molds. Several works have shown contamination of maize by this toxin. Fumonisin B1 (FB-1 is found in greatest proportion (about 70%, resistant to several industrialization processes. In that context, the objective of this work was to analyze the effect of administering a diet contaminated with FB-1 on the morphophysiology of the kidneys of 21-day old male Wistar rats. The animals were divided into 2 groups: G0 (with animals receiving feed free of FBs and G6 (6mg of FB1 kg-1 of feed. The diet was administered during 42 days. After that period, the animals were placed in metabolic cages for urine collection, blood was collected for analysis of plasma creatinine, and the kidneys were fixed and stained with Masson's trichrome. We observed that FB1 administration did not affect feed intake, body weight gain and animal growth. The normal levels of plasma creatinine suggest that the toxin did not lead to glomerular lesion. There was also no change in water intake, osmolarity and excretion of sodium in urine. However, there was a significant increase in urine volume and potassium excretion in urine, with mild tubulointerstitial changes in the outer cortex for the group receiving the mycotoxin.

    To systematically review and appraise studies examining self-administered physical activity questionnaires (PAQ) for the elderly. This article is one of a group of four articles in Sports Medicine on the content and measurement properties of PAQs. LITERATURE SEARCH METHODOLOGY: Searches in PubMed, EMBASE and SportDiscu (until May 2009) on self-administered PAQ. Inclusion criteria were as follows: (i) the study examined (at least one of) the measurement properties of a self-administered PAQ; (ii) the questionnaire aimed to measure physical activity (PA) in older people; (iii) the average age of the study population was >55 years; (iv) the article was written in English. We excluded PA interviews, diaries and studies that evaluated the measurement properties of a self-administered PAQ in a specific population, such as patients. We used a standard checklist (qualitative attributes and measurement properties of PA questionnaires [QAPAQ]) for appraising the measurement properties of PAQs. Eighteen articles on 13 PAQs were reviewed, including 16 reliability analyses and 25 validity analyses (of which 15 were on construct validity, seven on health/functioning associations, two on known-groups validity and one on responsiveness). Many studies suffered from methodological flaws, e.g. too small sample size or inadequate time interval between test and retest. Three PAQs received a positive rating on reliability: IPAQ-C (International Physical Activity Questionnaire-Chinese), intraclass correlation coefficient (ICC) > or = 0.81; WHI-PAQ (Women's Health Initiative-PAQ), ICC = 0.76; and PASE (Physical Activity Scale for the Elderly), Pearson correlation coefficient (r) = 0.84. However, PASE was negatively rated on reliability in another study (ICC = 0.65). One PAQ received a positive rating on construct validity: PASE against Mini-Logger (r > 0.52), but PASE was negatively rated in another study against accelerometer and another PAQ, Spearman correlation coefficient = 0.17 and 0

    Full Text Available Cyanogenic glycosides are present in several economically important plant foods. Amygdalin, one of the most common cyanoglucoside, can be found abundantly in the seeds of apples, bitter almonds, apricots, peaches, various beans, cereals, cassava and sorghum. Amygdalin has been used for the treatment of cancer, it shows killing effects on cancer cells by release of cyanide. However, its effect on bone structure has not been investigated to date. Therefore, the objective of this study was to determine a possible effect of amygdalin application on femoral bone microstructure in adult rabbits. Four month old rabbits were randomly divided into two groups of three animals each. Rabbits from E group received amygdalin intramuscularly at a dose 0.6 mg.kg-1 body weight (bw (group E, n = 3 one time per day during 28 days. The second group of rabbits without amygdalin supplementation served as a control (group C, n = 3. After 28 days, histological structure of femoral bones in both groups of rabbits was analysed and compared. Rabbits from E group displayed different microstructure in middle part of the compact bone and near endosteal bone surface. For endosteal border, an absence of the primary vascular longitudinal bone tissue was typical. This part of the bone was formed by irregular Haversian and/or by dense Haversian bone tissues. In the middle part of substantia compacta, primary vascular longitudinal bone tissue was observed. Cortical bone thickness did not change between rabbits from E and C groups. However, rabbits from E group had a significantly lower values of primary osteons' vascular canals and secondary osteons as compared to the C group. On the other hand, all measured parameters of Haversian canals did not differ between rabbits from both groups. Our results demonstrate that intramuscular application of amygdalin at the dose used in our study affects femoral bone microstructure in rabbits.

    Given the broad age range across which the quadrivalent meningococcal conjugate vaccine MenACWY-CRM is used, coadministration with routine vaccines should be evaluated across age groups for possible immunologic interference and impact on vaccine reactogenicity and safety. We summarize data from a large population of infants, adolescents and international travelers from 10 phase 3 or 4 clinical studies to evaluate coadministration of MenACWY-CRM with commonly administered vaccines. Noninferiority analyses of immune responses were performed across studies and age groups for each vaccine. Reactogenicity and safety were also assessed. In infants, MenACWY-CRM coadministered with routine vaccines did not reduce immune responses to diphtheria, tetanus, poliovirus, hepatitis B, Haemophilus influenzae type b, pneumococcal conjugate, measles-mumps-rubella, varicella or pertussis antigens. Noninferiority criteria were not met for some pneumococcal conjugate serotypes at 7 months of age, but no consistent trends were observed. In adolescents, coadministration did not reduce immune responses to tetanus, diphtheria and human papilloma virus vaccine antigens. Noninferiority criteria for pertussis antigens were not uniformly met in infant and adolescent studies, although the clinical relevance is unclear. In adults, coadministration did not reduce immune responses to hepatitis A/B, typhoid fever, yellow fever, Japanese encephalitis and rabies antigens. Immune responses to MenACWY-CRM were not impacted by coadministration of commonly administered vaccines. Coadministration did not increase frequencies of postvaccination adverse events in any age group. With no clinically relevant vaccine interactions or impact on vaccine reactogenicity or safety, these results support the coadministration of MenACWY-CRM with routine vaccines in all age groups.

    Opioid overdose rates continue to rise at an alarming rate. One method used to combat this epidemic is the administration of naloxone by law enforcement. Many cities have implemented police naloxone administration programs, but there is a minimal amount of research examining this policy. The following study examines data over 18 months, after implementation of a police naloxone program in an urban setting. We describe the most common indications and outcomes of naloxone administration as well as examine the incidence of arrest, immediate detention, or voluntary transport to the hospital. In doing so, this study seeks to describe the clinical factors surrounding police use of naloxone, and the effects of police administration. All police officer administrations were queried from April 2014 through September 2015 (n = 126). For each incident we collected the indication, response, and disposition of the patient that was recorded on a "sick-injured civilian" report that officers were required to complete after administration of naloxone. All of the relevant information was abstracted from this report into an electronic data collection form that was then input into SPSS for analysis. The most common indication for administration was unconscious/unresponsive (n = 117; 92.9%) followed by slowed breathing (n = 72; 57.1%), appeared blue (n = 63; 50.0%) and not breathing (n = 41; 32.5%). After administration of naloxone the majority of patients regained consciousness (n = 82; 65.1%) followed by began to breath (n = 71; 56.3%). However, in 17.5% (n = 22) of the cases "Nothing" happened when naloxone was administered. The majority of patients were transported voluntarily to the hospital (n = 122; 96.8%). Lastly, there was only one report where the patient became combative. Our study shows that police officers trained in naloxone administration can correctly recognize symptoms of opioid overdose, and can appropriately administer naloxone without significant adverse effects or

    In the last years, casein nanoparticles have been proposed as carriers for the oral delivery of biologically active compounds. However, till now, no information about their possible specific hazards in vivo was available. The aim of this work was to assess the safety of casein nanoparticles when administered orally to animals through a 90 days dose-repeated toxicity study (OECD guideline 408), that was performed in Wistar rats under GLP conditions. After 90 days, no evidences of significant alterations in animals treated daily with 50, 150 or 500 mg/kg bw of nanoparticles were found. This safety agrees well with the fact that nanoparticles were not absorbed and remained within the gut as observed by radiolabelling in the biodistribution study. After 28 days, there was a generalized hyperchloremia in males and females treated with the highest dose of 500 mg/kg bw, that was coupled with hypernatremia in the females. These effects were related to the presence of mannitol which was used as excipient in the formulation of casein nanoparticles. According to these results, the No Observed Adverse Effect Level (NOAEL) could be established in 150 mg/kg bw/day and the Lowest Observed Effect Level (LOEL) could be established in 500 mg/kg bw/day.

    Iron oxide nanoparticles (IONP) are being developed for use as a cancer treatment. They have demonstrated efficacy when used either as a monotherapy or in conjunction with conventional chemotherapy and radiation. The success of IONP as a therapeutic tool depends on the delivery of a safe and controlled cytotoxic thermal dose to tumor tissue following activation with an alternating magnetic field (AMF). Prior to clinical approval, knowledge of IONP toxicity, biodistribution and physiological clearance is essential. This preliminary time-course study determines the acute toxicity and biodistribution of 110 nm dextran-coated IONP (iron) in mice, 7 days post systemic, at doses of 0.4, 0.6, and 1.0 mg Fe/ g mouse bodyweight. Acute toxicity, manifested as changes in the behavior of mice, was only observed temporarily at 1.0 mg Fe/ g mouse bodyweight, the highest dose administered. Regardless of dose, mass spectrometry and histological analysis demonstrated over 3 mg Fe/g tissue in organs within the reticuloendotheilial system (i.e. liver, spleen, and lymph nodes). Other organs (brain, heart, lungs, and kidney) had less than 0.5 mg Fe/g tissue with iron predominantly confined to the organ vasculature.

    Monitoring arthropod movement is often required to better understand associated population dynamics, dispersal patterns, host plant preferences, and other ecological interactions. Arthropods are usually tracked in nature by tagging them with a unique mark and then re-collecting them over time and space to determine their dispersal capabilities. In addition to actual physical tags, such as colored dust or paint, various types of proteins have proven very effective for marking arthropods for ecological research. Proteins can be administered internally and/or externally. The proteins can then be detected on recaptured arthropods with a protein-specific enzyme-linked immunosorbent assay (ELISA). Here we describe protocols for externally and internally tagging arthropods with protein. Two simple experimental examples are demonstrated: (1) an internal protein mark introduced to an insect by providing a protein-enriched diet and (2) an external protein mark topically applied to an insect using a medical nebulizer. We then relate a step-by-step guide of the sandwich and indirect ELISA methods used to detect protein marks on the insects. In this demonstration, various aspects of the acquisition and detection of protein markers on arthropods for mark-release-recapture, mark-capture, and self-mark-capture types of research are discussed, along with the various ways that the immunomarking procedure has been adapted to suit a wide variety of research objectives.

  4. Association between systemically administered radioisotopes and subsequent malignant disease

    There is a long history recording the association of x radiation and the subsequent development of malignant tumors. For systemically administered isotopes this came into prominence when Martland discovered the association between cancer, particularly of the bone, and ingestion of radioactive isotopes by radium dial painters. This association was amplified by the development of cancer in patients given thorotrast as a contrast medium for diagnostic radiologic examination. Acute leukemia was reported 30 years ago in patients with polycythemia vera treated with 32 P. Acute leukemia also occurs in patients with polycythemia vera treated only with phlebotomy or drugs. A controlled study is now underway to provide a more definite answer to question what is the incidence of acute leukemia in patients with polycythemia vera treated by phlebotomy alone, chlorambucil, or 32 P. 131 I for the treatment of hyperthyroidism probably does not induce cancer, but in the doses used for thyroid cancer there was an increased incidence of neoplasms (12/200 in one study). This was higher than the expected incidence of neoplasms. The doses of radioactive isotopes used currently for diagnostic purposes have not induced cancer, but it is difficult and probably impossible to verify this with absolute certainty

    A survey of radiopharmaceutical activities used at the eight hospital centres specialising in paediatric nuclear medicine in Australia was conducted in 1999-2000 by the Australian and New Zealand Society of Nuclear Medicine and the Australasian Radiation Protection Society. Data on the maximum and minimum administered activities (A max and A min ) as obtained for 43 paediatric imaging procedures are presented. The results are also available on the ANZSNM and ARPS websites at: http://www.anzsnm.org.au and http://www.arps.org.au. The A max values were significantly less than the corresponding Reference Activities for adults determined in a previous study. Activities for individual patients are calculated using surface area scaling at five centres and body weight scaling at three centres. The median values of A max and A min are recommended as Paediatric Reference Activities. The effective dose to patients of various sizes for the Paediatric Reference Activities and both methods of scaling was calculated for each procedure.

    The roll-out of accessible and affordable antiretroviral (ARV) drugs for people living with HIV in low-income countries is drastically changing the nature of HIV-related healthcare. The Zimbabwean Ministry of Health has renewed efforts to make antiretroviral treatment (ART) for HIV free and publically available across the country. This paper describes the findings from a multi-method qualitative study including interviews and a focus group with healthcare workers (mostly nurses), totalling 25 participants, and field notes from over 100 hours of ethnographic observation in three rural Zimbabwean health centres. These health centres began providing free ARV drugs to HIV-positive people over one year prior to the research period. We examined sources of motivation and frustration among nurses administering ART in these resource-poor health centres. The findings suggest that healthcare workers administering ART in challenging circumstances are adept at drawing strength from the dramatic physical and emotional recoveries made possible by ART and from their personal memories of the suffering caused by HIV/AIDS among close friends or family. However, healthcare staff grappled with extreme resource shortages, which led to exhaustion and frustration. Surprisingly, only one year into ART provision, healthcare workers did not reference the professional challenges of their HIV work before ART became available, suggesting that medical breakthroughs such as ART rapidly come to be seen as a standard element of nursing. Our findings provide a basis for optimism that medical breakthroughs such as ART can reinvigorate healthcare workers in the short term. However, we caution that the daily challenges of nursing in poor environments, especially administering an ongoing and resource-intensive regime such as ART, must be addressed to enable nurses to continue delivering high-quality ART in sub-Saharan Africa.

    Full Text Available The objective of the present study was to investigate the relationships between terpenes’ intake and their presence in animal tissues (blood and milk as well as in the final product (cheese. Eight dairy goats were divided in two balanced groups, representing control (C and treatment (T group. In T group oral administration of a mixture of terpenes (α-pinene, limonene and β-caryophyllene was applied over a period of 18 d. Cheese was produced, from C and T groups separately, on three time points, twice during the period of terpenes’ oral administration and once after the end of experiment. Terpenes were identified in blood by extraction using petroleum ether and in milk and cheese by the use of solid phase micro-extraction (SPME method, followed by GC-MS analysis. Chemical properties of the milk and the produced cheeses were analyzed and found not differing between the two groups. Limonene and α-pinene were found in all blood and milk samples of the T group after a lag-phase of 3 d, while β-caryophyllene was determined only in few milk samples. Moreover, none of the terpenes were traced in blood and milk of C animals. In cheese, terpenes’ concentrations presented a more complicated pattern implying that terpenes may not be reliable feed tracers. We concluded that monoterpenes can be regarded as potential feed tracers for authentification of goat milk, but further research is required on factors affecting their transfer.

    The supplementation of a breakfast by 10 g of guar, pectin, agar or locust bean gum in powder form in 13 maturity onset, non-insulin dependent diabetics failed to decrease significantly the post-prandial rise in plasma glucose and insulin seen after a similar meal without the supplement. The values of one hour post-prandial increment in blood glucose seen with guar powder were, for control meal (mean +/- SEM) 5.8 %/- 0.4 mmol/l, for test, 5.7 +/- 0.5; with pectin powder, control 6.4 +/- 0.8 mmol/l, test 5.0 +/- 1.2 mmol/l; with agar powder, control 7.5 +/- 1.0, test 7.0 +/- 0.5; with locust bean gum powder, control 5.9 +/- 1.0, test 5.0 +/- 0.7. The equivalent values for one hour insulin (microU/ml, mean +/- SEM) were, for guar powder, 51 +/0 21 and 51 +/- 16; for pectin powder 60 +/- 24 and 63 +/- 17; for agar powder, 27 +/- 9 and 36 +/- 11 and, for locust bean gum powder 53 +/- 26 and 62 +/- 18. The guar, pectin and locust gum tended to form lumps, and all the substances tested were unpalatable in powder form producing feelings of abdominal discomfort and abnormal fullness. Administering the same quantity of guar or pectin in a well hydrated form (but not premixed with the carbohydrate portion of the food) to the same people under identical conditions did not enhance its effectiveness. Supplementing diets with any of these sources of dietary fibre in either of these forms and in these amounts is unlikely to be beneficial in the management of non-insulin dependent diabetes.

    Full Text Available Abstract Background High dose of corticosteroids has been previously shown to protect against controlled mechanical ventilation (CMV-induced diaphragmatic dysfunction while inhibiting calpain activation. Because literature suggests that the calpain inhibiting effect of corticosteroid depends on the dose administered, we determined whether lower doses of corticosteroids would also provide protection of the diaphragm during CMV. This may be important for patients undergoing mechanical ventilation and receiving corticosteroids. Methods Rats were assigned to controls or to 24 hours of CMV while being treated at the start of mechanical ventilation with a single intramuscular administration of either saline, or 5 mg/kg (low MP or 30 mg/kg (high MP of methylprednisolone. Results Diaphragmatic force was decreased after CMV and this was exacerbated in the low MP group while high MP rescued this diaphragmatic dysfunction. Atrophy was more severe in the low MP group than after CMV while no atrophy was observed in the high MP group. A significant and similar increase in calpain activity was observed in both the low MP and CMV groups whereas the high dose prevented calpain activation. Expression of calpastatin, the endogenous inhibitor of calpain, was decreased in the CMV and low MP groups but its level was preserved to controls in the high MP group. Caspase-3 activity increased in all CMV groups but to a lesser extent in the low and high MP groups. The 20S proteasome activity was increased in CMV only. Conclusions Administration of 30 mg/kg methylprednisolone during CMV protected against CMV-induced diaphragm dysfunction while 5 mg/kg was more deleterious. The protective effect is due mainly to an inhibition of the calpain system through preservation of calpastatin levels and to a lesser extent to a caspase-3 inhibition.

  10. Tolerability assessment of a lectin fraction from Tepary bean seeds (Phaseolus acutifolius orally administered to rats

    2015-01-01

    Full Text Available Our previous studies have shown that a lectin rich fraction (TBLF extracted from Tepary bean seeds differentially inhibits cancer cells proliferation in vitro. Before testing the in vivo anticancer effect, the acute and subchronic toxicological assays in rats were conducted, where an oral dose of 50 mg/body weight kg was determined as the NOAEL. This study evaluated the resistance to digestion and complete blood count (CBC after 24 h of the orally administered 50 mg/kg TBLF. The digestion resistance test showed lectins activity retention after 72 h and the CBC study showed a high level of eosinophils, suggesting an allergic-like response. Tolerability was assayed after 6 weeks of treatment by dosing with an intragastric cannula every third day per week. It was observed a transient reduction in food intake and body weight in the first weeks, resulting in body weight gain reduction of 10% respect to the control group at the end of the study. Additionally, organs weight, histopathological analysis and blood markers for nutritional status and for liver, pancreas and renal function were not affected. Our results suggest that 50 mg/kg TBLF administered by oral route, exhibit no toxicity in rats and it was well tolerated. Further studies will focus on long-term studies.

    This study was conducted to determine the effect of training administered to working mothers and its duration on maternal anxiety levels and breastfeeding habits. Within the scope of Health for All in the 21st Century project, a goal was set to increase the rate of infants fed exclusively by breastfeeding during the first six months of life to 80% by the year 2015. A randomised design with repeated measures. During collection of pretest data, a Personal Information Form, a Questionnaire Form and a State Trait Anxiety Inventory were administered to the mothers in the experimental and control groups. Five home visits were conducted starting two weeks before the date when mothers returned to work and ending when the infants became six months old. Breastfeeding techniques were taught to these mothers. Data were subjected to Proc MEAN, FREQ, anova and GENMOD procedures. The rate of natural feeding (breastfeeding exclusively) among trained mothers was greater than untrained mothers. The frequency of breastfeeding affects maternal anxiety levels; the anxiety level of mothers decreased with increasing frequency of breastfeeding. Educating working mothers about breastfeeding reduces their anxiety levels and influences positively their breastfeeding habits. With the support of health-care staff to increase awareness and knowledge on the value and sufficiency of breast milk, the rate and period of natural feeding increased significantly among working mothers. © 2011 Blackwell Publishing Ltd.

    Inferior alveolar nerve block (IANB) of the mandible is commonly used in the oral cavity as an anesthetic technique for dental procedures. This study evaluated the success rate of the first IANB administered by dental practitioners. Volunteer dental practitioners at Mahidol University who had never performed an INAB carried out 106 INAB procedures. The practitioners were divided into 12 groups with their advisors by randomized control trials. We recorded the success rate via pain visual analog scale (VAS) scores. A large percentage of the dental practitioners (85.26%) used the standard method to locate the anatomical landmarks, injecting the local anesthetic at the correct position, with the barrel of the syringe parallel to the occlusal plane of the mandibular teeth. Further, 68.42% of the dental practitioners injected the local anesthetic on the right side by using the left index finger for retraction. The onset time was approximately 0-5 mins for nearly half of the dental practitioners (47.37% for subjective onset and 43.16% for objective onset), while the duration of the IANB was approximately 240-300 minutes (36.84%) after the initiation of numbness. Moreover, the VAS pain scores were 2.5 ± 1.85 and 2.1 ± 1.8 while injecting and delivering local anesthesia, respectively. The only recorded factor that affected the success of the local anesthetic was the administering practitioner. This reinforces the notion that local anesthesia administration is a technique-sensitive procedure.

    The correction or maintenance of blood and tissue alpha-tocopherol (alpha-Toc) levels by intraperitoneally administered all-rac-alpha-tocopheryl acetate (alpha-Tac) was compared with RRR- alpha-tocopherol (alpha-Toc) in vitamin E-depleted and control rats. Rats received 1.3 TE vitamin E daily for 7 days. alpha-Tac was detected in plasma of one-third of alpha-Tac-treated rats 24 hr after the first treatment, although not in subsequent samplings. Both alpha-Tac and alpha-Toc increased tocopherol levels in plasma and liver of E-deprived rats, while little or no change was observed in adipose tissue and brain. Similarly, control rats treated with alpha-Tac or alpha-Toc had significantly greater (p less than 0.05) plasma and liver alpha-Toc levels at day 3 and day 7 than did saline-treated rats. There was no significant difference in adipose alpha-Toc levels among treatment groups of control rats. The results of this study suggest that alpha-Tac is rapidly hydrolyzed to its biologically active alcohol form and results in similar effects to that of intraperitoneally administered alpha-Toc.

    To determine the pharmacokinetic parameters of xylazine, ketamine, and butorphanol (XKB) administered IM and sodium salicylate (SAL) administered PO to calves and to compare drug effects on biomarkers of pain and distress following sham and actual castration and dehorning. 40 Holstein bull calves from 3 farms. Calves weighing 108 to 235 kg (n = 10 calves/group) received one of the following treatments prior to sham (period 1) and actual (period 2) castration and dehorning: saline (0.9% NaCl) solution IM (placebo); SAL administered PO through drinking water at concentrations from 2.5 to 5 mg/mL from 24 hours prior to period 1 to 48 hours after period 2; butorphanol (0.025 mg/kg), xylazine (0.05 mg/kg), and ketamine (0.1 mg/kg) coadministered IM immediately prior to both periods; and a combination of SAL and XKB (SAL+XKB). Plasma drug concentrations, average daily gain (ADG), chute exit velocity, serum cortisol concentrations, and electrodermal activity were evaluated. ADG (days 0 to 13) was significantly greater in the SAL and SAL+XKB groups than in the other 2 groups. Calves receiving XKB had reduced chute exit velocity in both periods. Serum cortisol concentrations increased in all groups from period 1 to period 2. However, XKB attenuated the cortisol response for the first hour after castration and dehorning and oral SAL administration reduced the response from 1 to 6 hours. Administration of XKB decreased electrodermal activity scores in both periods. SAL administered PO through drinking water decreased cortisol concentrations and reduced the decrease in ADG associated with castration and dehorning in calves.

    This project is currently under contract for research through the Department of Homeland Security until 2011. The group I was responsible for studying has to remain confidential so as not to affect the current project. All dates, reference links and authors, and other distinguishing characteristics of the original group have been removed from this report. All references to the name of this group or the individual splinter groups has been changed to 'Group X'. I have been collecting texts from a variety of sources intended for the use of recruiting and radicalizing members for Group X splinter groups for the purpose of researching the motivation and intent of leaders of those groups and their influence over the likelihood of group radicalization. This work included visiting many Group X websites to find information on splinter group leaders and finding their statements to new and old members. This proved difficult because the splinter groups of Group X are united in beliefs, but differ in public opinion. They are eager to tear each other down, prove their superiority, and yet remain anonymous. After a few weeks of intense searching, a list of eight recruiting texts and eight radicalizing texts from a variety of Group X leaders were compiled.

    Methamphetamine is a highly addictive psychomotor stimulant yet the neurobiological consequences of methamphetamine self-administration remain under-characterized. Thus, we employed microdialysis in rats trained to self-administer intravenous (IV) infusions of methamphetamine (METH-SA) or saline (SAL) and a group of rats receiving non-contingent IV infusions of methamphetamine (METH-NC) at 1 or 21 days withdrawal to determine the dopamine and glutamate responses in the nucleus accumbens (NAC) to a 2 mg/kg methamphetamine intraperitoneal challenge. Furthermore, basal NAC extracellular glutamate content was assessed employing no net-flux procedures in these three groups at both time points. At both 1- and 21-day withdrawal points, methamphetamine elicited a rise in extracellular dopamine in SAL animals and this effect was sensitized in METH-NC rats. However, METH-SA animals showed a much greater sensitized dopamine response to the drug challenge compared with the other groups. Additionally, acute methamphetamine decreased extracellular glutamate in both SAL and METH-NC animals at both time-points. In contrast, METH-SA rats exhibited a modest and delayed rise in glutamate at 1-day withdrawal and this rise was sensitized at 21 days withdrawal. Finally, no net-flux microdialysis revealed elevated basal glutamate and increased extraction fraction at both withdrawal time-points in METH-SA rats. Although METH-NC rats exhibited no change in the glutamate extraction fraction, they exhibited a time-dependent elevation in basal glutamate levels. These data illustrate for the first time that a history of methamphetamine self-administration produces enduring changes in NAC neurotransmission and that non-pharmacological factors have a critical role in the expression of these methamphetamine-induced neurochemical adaptations.

  19. Molecular interactions of agonist and inverse agonist ligands at serotonin 5-HT2C G protein-coupled receptors: computational ligand docking and molecular dynamics studies validated by experimental mutagenesis results

    2015-02-01

    To understand molecular determinants for ligand activation of the serotonin 5-HT2C G protein-coupled receptor (GPCR), a drug target for obesity and neuropsychiatric disorders, a 5-HT2C homology model was built according to an adrenergic β2 GPCR (β2AR) structure and validated using a 5-HT2B GPCR crystal structure. The models were equilibrated in a simulated phosphatidyl choline membrane for ligand docking and molecular dynamics studies. Ligands included (2S, 4R)-(-)-trans-4-(3'-bromo- and trifluoro-phenyl)-N,N-dimethyl-1,2,3,4-tetrahydronaphthalene-2-amine (3'-Br-PAT and 3'-CF3-PAT), a 5-HT2C agonist and inverse agonist, respectively. Distinct interactions of 3'-Br-PAT and 3'-CF3-PAT at the wild-type (WT) 5-HT2C receptor model were observed and experimental 5-HT2C receptor mutagenesis studies were undertaken to validate the modelling results. For example, the inverse agonist 3'-CF3-PAT docked deeper in the WT 5-HT2C binding pocket and altered the orientation of transmembrane helices (TM) 6 in comparison to the agonist 3'-Br-PAT, suggesting that changes in TM orientation that result from ligand binding impact function. For both PATs, mutation of 5-HT2C residues S3.36, T3.37, and F5.47 to alanine resulted in significantly decreased affinity, as predicted from modelling results. It was concluded that upon PAT binding, 5-HT2C residues T3.37 and F5.47 in TMs 3 and 5, respectively, engage in inter-helical interactions with TMs 4 and 6, respectively. The movement of TMs 5 and 6 upon agonist and inverse agonist ligand binding observed in the 5-HT2C receptor modelling studies was similar to movements reported for the activation and deactivation of the β2AR, suggesting common mechanisms among aminergic neurotransmitter GPCRs.

    To gain a deeper insight into the potential interactions between individual aromatic hydrocarbons in a mixture, several benzo[a]pyrene (B[a]P) and 7H-dibenzo[c,g]carbazole (DBC) binary mixtures were studied. The biological activity of the binary mixtures was investigated in the HepG2 and WB-F344 liver cell lines and the Chinese hamster V79 cell line that stably expresses the human cytochrome P4501A1 (hCYP1A1). In the V79 cells, binary mixtures, in contrast to individual carcinogens, caused a significant decrease in the levels of micronuclei, DNA adducts and gene mutations, but not in cell survival. Similarly, a lower frequency of micronuclei and levels of DNA adducts were found in rat liver WB-F344 cells treated with a binary mixture, regardless of the exposure time. The observed antagonism between B[a]P and DBC may be due to an inhibition of Cyp1a1 expression because cells exposed to B[a]P:DBC showed a decrease in Cyp1a1 mRNA levels. In human liver HepG2 cells exposed to binary mixtures for 2 h, a reduction in micronuclei frequency was also found. However, after a 24 h treatment, synergism between B[a]P and DBC was determined based on DNA adduct formation. Accordingly, the up-regulation of CYP1A1 expression was detected in HepG2 cells exposed to B[a]P:DBC. Our results show significant differences in the response of human and rat cells to B[a]P:DBC mixtures and stress the need to use multiple experimental systems when evaluating the potential risk of environmental pollutants. Our data also indicate that an increased expression of CYP1A1 results in a synergistic effect of B[a]P and DBC in human cells. As humans are exposed to a plethora of noxious chemicals, our results have important implications for human carcinogenesis. - Highlights: • B[a]P:DBC mixtures were less genotoxic in V79MZh1A1 cells than B[a]P and DBC alone. • An antagonism between B[a]P and DBC was determined in rat liver WB-F344 cells. • The inhibition of CYP1a1 expression by B[a]P:DBC mixture

    Dingman, Deirdre A; Schmit, Cason D

    One strategy to increase the uptake of human papillomavirus (HPV) vaccine among adolescents is through the use of pharmacists. Our objectives were to (1) use a publicly available database to describe the statutory and regulatory authority of pharmacists to administer the HPV vaccine in the United States and (2) discuss how the current status of laws may influence achievement of the Healthy People 2020 goal of 80% HPV vaccination rate for teenagers aged 13-15. Using information from the Centers for Disease Control and Prevention's (CDC's) Public Health Law Program database, we identified state laws in effect as of January 1, 2016, giving pharmacists authority to administer vaccines. We used a standardized analysis algorithm to determine whether states' laws (1) authorized pharmacists to administer HPV vaccine, (2) required third-party authorization for pharmacist administration, and (3) restricted HPV vaccine administration by pharmacists to certain patient age groups. Of 50 states and the District of Columbia, 40 had laws expressly granting pharmacists authority to administer HPV vaccine to patients, but only 22 had laws that authorized pharmacists to vaccinate preadolescents aged 11 or 12 (ie, the CDC-recommended age group). Pharmacists were granted prescriptive authority by 5 states, and they were given authority pursuant to general (non-patient-specific) third-party authorization (eg, a licensed health care provider) by 32 states or patient-specific third-party authorization by 3 states. Most states permitted pharmacists to administer HPV vaccines only to boys and girls older than 11 or 12, which may hinder achievement of the Healthy People 2020 goal for HPV vaccination. Efforts should be made to strengthen the role of pharmacists in addressing this public health issue.

    Self-administered foot reflexology is unrestricted by time and space, economical, and practical because it is easy to learn and apply. This study estimated the effectiveness of self-foot reflexology for symptom management in healthy persons through a systematic review and meta-analysis. The participants were healthy persons not diagnosed with a specific disease. The intervention was foot reflexology administered by participants, not by practitioners or healthcare providers. The comparative studies either between groups or within group comparison were included. Our search utilized core databases (MEDLINE, EMBASE, Cochrane, and CINAHL). We also searched Chinese (CNKI), Japanese (J-STAGE), and Korean databases (KoreaMed, KMbase, KISS, NDSL, KISTI, and OASIS). The search was used MeSH terminology and key words (foot reflexology, foot massage, and self). Analysis of three non-randomized trials and three before-and-after studies showed that self-administered foot reflexology resulted in significant improvement in subjective outcomes such as perceived stress, fatigue, and depression. However, there was no significant improvement in objective outcomes such as cortisol levels, blood pressure, and pulse rate. We did not find any randomized controlled trial. This study presents the effectiveness of self-administered foot reflexology for healthy persons' psychological and physiological symptoms. While objective outcomes showed limited results, significant improvements were found in subjective outcomes. However, owing to the small number of studies and methodological flaws, there was insufficient evidence supporting the use of self-performed foot reflexology. Well-designed randomized controlled trials are needed to assess the effect of self-administered foot reflexology in healthy people. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The objectives of this study were to evaluate the effects of intravenous acetate Ringer's solution, with or without dextrose, on diarrheic calves with either experimentally induced or spontaneous diarrhea. In the experimental model, diarrhea was induced in nine healthy calves by administering cold milk (below 4°C) twice a day for 2 days. The calves were randomly assigned to the isotonic saline (ISS), acetated Ringer's (AR) or acetated Ringer's with 5% dextrose (ARD) groups, with three calves assigned to each group. The calves received 80 ml/kg of their designated solution, at a flow rate of 20 ml/kg/hr. Infusion of ISS, AR and ARD were all found to be safe and effective in increasing plasma volume. Intravenous (IV) infusion of ISS resulted in the acidification secondary to dilution, while AR and ARD infusion inhibited acidification. In addition, prevention of catabolism was observed only with IV infusion of ARD. Sixteen calves with spontaneous diarrhea were enrolled in the clinical study. The calves were randomly assigned to the AR or ARD groups, with eight calves being assigned to each group. The calves received 100 ml/kg of their designated solution, at a flow rate of 25 ml/kg/hr. Intravenous infusion of AR and ARD was found to be effective in increasing plasma volume and inhibiting acidification. Only infusion of ARD prevented catabolism, but it also led to hyperglycemia. Our results suggest that a solution containing dextrose may be beneficial for wasting diarrheic calves.

    Nuclear medicine procedures have carried out in the Clinical Center of Montenegro - Podgorica since 2006 by the dual-headed SPECT and Digital gamma camera NUCLINE Spirit DH-V. In the first six months of the gamma camera use (from September 2006 to March 2007) examinations of skeleton, kidneys, thyroid and lung were performed. For diagnostic skeletal imaging (102 patients) the radiopharmaceutical 99m Tc-MDP is used, and administered activities were in the range from 555 to 740 MBq. For thyroid imaging (203 patients) 99m Tc-pertechnetate is used, and administered activities were in the range (37-111) MBq. Lung imaging is performed for 3 patients, using 99m Tc-MAA and administered activities in the range (111-185) MBq. Renal imaging is carried out for 72 patients: 42 dynamic studies of kidneys were performed with 99m Tc-DTPA and administered activities from 207 to 282 MBq, and 30 static kidneys scintigraphies were performed using the radiopharmaceutical 99m Tc-DMSA. 6 patients in the last mentioned group were children with year of birth between 2000 and 2006, and administered activities were from 16.6 to 55.5 MBq. In the same group, activities 28.5 MBq, 74.4 MBq and 120 MBq were administered to three patients with age between 6 and 18 years, and in the other cases, administered activities to the patients (adults) were in the range (59.2 to 196) MBq. The administered activities presented here are basis for further estimations of cumulated activity and absorbed dose to the various organs, which is useful for comparison of the average dose to patient organs in various nuclear medicine procedures and calculation of effective dose equivalent and total effective dose, significant for an estimation of potential risk due to the radioactivity administered to a patient during nuclear medicine procedures. It is very important for procedures optimization and improvement of the radiation protection. (author)

    The aim of the present study was to determine the optimum activity of the Cuban MDP labeled with Tc-99 m, for establishing a compromise relation between image quality and patient radiological protection in Nuclear Medicine studies. The used statistical technique was the discriminant analysis to arrive at the optimization criterion. Three samples of 18 patients each were selected. Each sample was undergone to a different acquisition protocol. Each sample was divided into three groups of 6 patients each. The administered activities were: 293 MBq, 430 MBq or 598 MBq. Images of hands and femurs were graded for each study. The ratios Signal /Background and Signal/ Noise were processed. The value of 430 MBq was enough to obtain good image quality using a protocol of 10 minutes of acquisition for the used technical conditions. (author)

    Spreadsheet templates have been developed by the authors to calculate radiation exposures to others from patients to whom radioactive materials have been administered (or, indeed, from any source of radiation exposure) to be readily calculated. The time during which contact should be avoided, along with the residual activity at resumption of contact is also calculated using an iterative technique. These spreadsheets allow a great deal of flexibility in the specification of clearance rates and close contact patterns for individual patients. Estimates of doses, restriction times and residual activities for 131 l thyrotoxic therapy, for various contact patterns and group of patients, were calculated. The spreadsheets are implemented using Microsoft EXCEL for both PC and Macintosh computers, and are readily available from the authors

    Hypotension occurs during cardiopulmonary bypass (CPB), in part because of induction of the inflammatory response, for which nitric oxide and guanylate cyclase play a central role. In this study we examined the hemodynamic effects of methylene blue (MB), an inhibitor of guanylate cyclase, administered during cardiopulmonary bypass (CPB) to patients taking angiotensin-converting enzyme inhibitors. Thirty patients undergoing cardiac surgery were randomized to receive either MB (3 mg/kg) or saline (S) after institution of CPB and cardioplegic arrest. CPB was managed similarly for all study patients. Hemodynamic data were assessed before, during, and after CPB. The use of vasopressors was recorded. All study patients experienced a similar reduction in mean arterial blood pressure (MAP) and systemic vascular resistance (SVR) with the onset of CPB and cardioplegic arrest. MB increased MAP and SVR and this effect lasted for 40 minutes. The saline group demonstrated a persistently reduced MAP and SVR throughout CPB. The saline group received phenylephrine more frequently during CPB, and more norepinephrine after CPB to maintain a desirable MAP. The MB group recorded significantly lower serum lactate levels despite equal or greater MAP and SVR. In conclusion, administration of MB after institution of CPB for patients taking angiotensin-converting enzyme inhibitors increased MAP and SVR and reduced the need for vasopressors. Furthermore, serum lactate levels were lower in MB patients, suggesting more favorable tissue perfusion.

    Full Text Available BACKGROUND: With a wide range of applications, titanium dioxide (TiO₂ nanoparticles (NPs are manufactured worldwide in large quantities. Recently, in the field of nanomedicine, intravenous injection of TiO₂ nanoparticulate carriers directly into the bloodstream has raised public concerns on their toxicity to humans. METHODS: In this study, mice were injected intravenously with a single dose of TiO₂ NPs at varying dose levels (0, 140, 300, 645, or 1387 mg/kg. Animal mortality, blood biochemistry, hematology, genotoxicity and histopathology were investigated 14 days after treatment. RESULTS: Death of mice in the highest dose (1387 mg/kg group was observed at day two after TiO₂ NPs injection. At day 7, acute toxicity symptoms, such as decreased physical activity and decreased intake of food and water, were observed in the highest dose group. Hematological analysis and the micronucleus test showed no significant acute hematological or genetic toxicity except an increase in the white blood cell (WBC count among mice 645 mg/kg dose group. However, the spleen of the mice showed significantly higher tissue weight/body weight (BW coefficients, and lower liver and kidney coefficients in the TiO₂ NPs treated mice compared to control. The biochemical parameters and histological tissue sections indicated that TiO₂ NPs treatment could induce different degrees of damage in the brain, lung, spleen, liver and kidneys. However, no pathological effects were observed in the heart in TiO₂ NPs treated mice. CONCLUSIONS: Intravenous injection of TiO₂ NPs at high doses in mice could cause acute toxicity effects in the brain, lung, spleen, liver, and kidney. No significant hematological or genetic toxicity was observed.

    The ability to compare symbolic numerical magnitudes correlates with children's concurrent and future mathematics achievement. We developed and evaluated a quick timed paper-and-pencil measure that can easily be used, for example in large-scale research, in which children have to cross out the numerically larger of two Arabic one- and two-digit numbers (SYMP Test). We investigated performance on this test in 1,588 primary school children (Grades 1-6) and examined in each grade its associations with mathematics achievement. The SYMP Test had satisfactory test-retest reliability. The SYMP Test showed significant and stable correlations with mathematics achievement for both one-digit and two-digit comparison, across all grades. This replicates the previously observed association between symbolic numerical magnitude processing and mathematics achievement, but extends it by showing that the association is observed in all grades in primary education and occurs for single- as well as multi-digit processing. Children with mathematical learning difficulties performed significantly lower on one-digit comparison and two-digit comparison in all grades. This all suggests satisfactory construct and criterion-related validity of the SYMP Test, which can be used in research, when performing large-scale (intervention) studies, and by practitioners, as screening measure to identify children at risk for mathematical difficulties or dyscalculia.

    Full Text Available Agmatine, an endogenous polyamine and putative neuromodulator, is known to have neuroprotective effects on various neurons in the central nervous system. We determined whether or not topically administered agmatine could reduce ischemic retinal injury. Transient ocular ischemia was achieved by intraluminal occlusion of the middle cerebral artery of ddY mice (30-35 g for 2 h, which is known to also induce occlusion of the ophthalmic artery. In the agmatine group (N = 6, a 1.0 mM agmatine-containing ophthalmic solution was administered four times daily for 2 weeks before occlusion. In the control group (N = 6, a 0.1% hyaluronic acid ophthalmic solution was instilled at the same times. At 22 h after reperfusion, the eyeballs were enucleated and the retinal sections were stained by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL. Transient ocular ischemia induced apoptosis of retinal cells in the entire retinal layer, and topically administered agmatine can significantly reduce this ischemic retinal injury. The proportion of apoptotic cells was definitely decreased (P < 0.001; Kruskal-Wallis test. Overall, we determined that topical agmatine application effectively decreases retinal damage in an in vivo ocular ischemic injury model. This implies that agmatine is a good candidate as a direct neuroprotective agent for eyes with ocular ischemic diseases.

    Antithymocyte globulin rabbit (r-ATG) has been used for the treatment and prevention of acute rejection in renal transplant recipients (RTR). Current manufacturer recommendations for r-ATG dictate the need for administration through a high-flow vein (central line). Previous studies have shown peripheral administration of r-ATG to be safe; however, these studies suggest the co-administration of heparin and hydrocortisone and did not compare the infusion-site reaction rates to a control group. A retrospective analysis was conducted of adult RTR receiving r-ATG or basiliximab between January 2004 and October 2006. Each agent was administered through a dedicated peripheral line. The primary endpoint was the incidence of infusion-site reactions. Other endpoints included the need to replace the intravenous catheter and the incidence of systemic thrombosis within 1 month of transplantation. During the study period, 152 peripheral infusions of r-ATG and 92 peripheral infusions of basiliximab were administered. No difference in infusion-site reactions was noted between the groups. There was also no difference either in the need for peripheral line replacement or the rates of systemic thrombosis. Peripheral administration of r-ATG is safe and can be infused without concomitant heparin and hydrocortisone. This method of r-ATG infusion was shown to be as safe as peripherally administered basiliximab.

    The recent scale-up of prevention of mother-to-child transmission of HIV (PMTCT) services has rapidly accelerated antiretroviral therapy (ART) uptake among pregnant and postpartum women in sub-Saharan Africa. The Mother and Infant Retention for Health (MIR4Health) study evaluates the impact of a combination intervention administered by trained lay health workers to decrease attrition among HIV-positive women initiating PMTCT services and their infants through 6 months postpartum. This was a qualitative study nested within the MIR4Health trial. MIR4Health was conducted at 10 health facilities in Nyanza, Kenya from September 2013 to September 2015. The trial intervention addressed behavioral, social, and structural barriers to PMTCT retention and included: appointment reminders via text and phone calls, follow-up and tracking for missed clinic visits, PMTCT health education at home visits and during clinic visits, and retention and adherence support and counseling. All interventions were administered by lay health workers. We describe results of a nested small qualitative inquiry which conducted two focus groups to assess the experiences and perceptions of lay health workers administering the interventions. Discussions were recorded and simultaneously transcribed and translated into English. Data were analyzed using framework analysis approach. Study findings show lay health workers played a critical role supporting mothers in PMTCT services across a range of behavioral, social, and structural domains, including improved communication and contact, health education, peer support, and patient advocacy and assistance. Findings also identified barriers to the uptake and implementation of the interventions, such as concerns about privacy and stigma, and the limitations of the healthcare system including healthcare worker attitudes. Overall, study findings indicate that lay health workers found the interventions to be feasible, acceptable, and well received by clients. Lay

    Characterizing the variability in transcript levels across breeds and sex in swine for genes that play a role in drug metabolism may shed light on breed and sex differences in drug metabolism. The objective of the study is to determine if there is heterogeneity between swine breeds and sex in transcript levels for genes previously shown to play a role in drug metabolism for animals administered flunixin meglumine or fenbendazole. Crossbred nursery female and castrated male pigs (n = 169) spread across 5 groups were utilized. Sires (n = 15) of the pigs were purebred Duroc, Landrace, Yorkshire or Hampshire boars mated to a common sow population. Animals were randomly placed into the following treatments: no drug (control), flunixin meglumine, or fenbendazole. One hour after the second dosing, animals were sacrificed and liver samples collected. Quantitative Real-Time PCR was used to measure liver gene expression of the following genes: SULT1A1, ABCB1, CYP1A2, CYP2E1, CYP3A22 and CYP3A29. The control animals were used to investigate baseline transcript level differences across breed and sex. Post drug administration transcript differences across breed and sex were investigated by comparing animals administered the drug to the controls. Contrasts to determine fold change were constructed from a model that included fixed and random effects within each drug. Significant (P-value fenbendazole, respectively. The current analysis found transcript level differences across swine breeds and sex for multiple genes, which provides greater insight into the relationship between flunixin meglumine and fenbendazole and known drug metabolizing genes.

    The purpose of this study was to investigate the preventive effects of topical application of green tea catechins on tongue oxidative stress induced by 5-fluorouracil (5-FU) administration in rats. Male Wistar rats (n=28, 8 weeks old) were divided into four groups of seven rats each: a negative control group (saline administration and application of ointment without green tea catechins), a positive control group (5-FU administration and application of ointment without green tea catechins), and two experimental groups (5-FU administration and application of ointment containing 0.1% or 0.5% green tea catechins). Topical application of each ointment to the ventral surface of the tongue was performed once a day for 5days. The level of 8-hydroxydeoxyguanosine (8-OHdG) was determined to evaluate oxidative stress. Fluorescence staining was also performed to confirm nuclear factor erythroid 2-related factor 2 (Nrf2) translocation to the nucleus. After the experimental period, the ratios of 8-OHdG-positive cells in the ventral tongue tissue were higher in the positive control group than in the negative control group (Ptea catechin group, but not in the 0.1% green tea catechin group, were lower than the positive control group (Ptea catechin group than in the positive control group (Ptea catechins could prevent tongue oxidative stress in 5-FU administered rats, via up-regulation of the Nrf2 signaling pathway.

    The article presents a study that aims at the apprehension of the group learning in a top management team composed by teachers in a Brazilian Waldorf school whose management is collective. After deciding to extend the school, they had problems recruiting teachers who were already trained based...... on the Steiner´s ideas, which created practical problems for conducting management activities. The research seeks to understand how that group of teachers collectively manage the school, facing the lack of resources, a significant heterogeneity in the relationships, and the conflicts and contradictions......, and they are interrelated to the group learning as the construction, maintenance and reconstruction of the intelligibility of practices. From this perspective, it can be said that learning is a practice and not an exceptional phenomenon. Building, maintaining and rebuilding the intelligibility is the group learning...

    Fuchs, László

    2015-01-01

    Written by one of the subject’s foremost experts, this book focuses on the central developments and modern methods of the advanced theory of abelian groups, while remaining accessible, as an introduction and reference, to the non-specialist. It provides a coherent source for results scattered throughout the research literature with lots of new proofs. The presentation highlights major trends that have radically changed the modern character of the subject, in particular, the use of homological methods in the structure theory of various classes of abelian groups, and the use of advanced set-theoretical methods in the study of undecidability problems. The treatment of the latter trend includes Shelah’s seminal work on the undecidability in ZFC of Whitehead’s Problem; while the treatment of the former trend includes an extensive (but non-exhaustive) study of p-groups, torsion-free groups, mixed groups, and important classes of groups arising from ring theory. To prepare the reader to tackle these topics, th...

  13. Reducing children's social anxiety symptoms: exploring a novel parent-administered cognitive bias modification training intervention.

    Social fears and worries in children are common and impairing. Yet, questions have been raised over the efficacy, suitability and accessibility of current frontline treatments. Here, we present data on the effectiveness of a novel parent-administered Cognitive Bias Modification of Interpretations (CBM-I) training tool. CBM-I capitalises on findings demonstrating an association between anxiety symptoms and biased interpretations, the tendency to interpret ambiguous situations negatively. Through CBM-I training, participants are exposed to benign resolutions, and reinforced for selecting these. In adults and adolescents, CBM-I training is effective at reducing symptoms and mood reactivity. In the present study, we developed a novel, child-appropriate form of CBM-I training, by presenting training materials within bedtime stories, read by a parent to the child across three consecutive evenings. Compared to a test-retest control group (n = 17), children receiving CBM-I (n = 19) reported greater endorsement of benign interpretations of ambiguous situations post-training (compared to pre-training). These participants (but not the test-retest control group) also showed a significant reduction in social anxiety symptoms. Pending replication and extensions to a clinical sample, these data may implicate a cost-effective, mechanism-driven and developmentally-appropriate resource for targeting social anxiety problems in children.

    The objective of this study was to test if and how self-administered practice of relaxation techniques, positive affirmation and guided imagery, in the final part of pregnancy had an impact on giving birth. Further to see if the use of a simple method, a CD with a booklet, with no previous training or specific support of the participants (neither required nor delivered), affected the birth experience. Outcome measures were monitored both during and after delivery: During delivery, pain and anxiety were measured at different stages of birth. Post-delivery Wellbeing (Edmonton Scale 0-10, where 10 is the worst possible feeling of Wellbeing), pain, anxiety, Apgar score, duration of birth, complications and anesthesia/analgesic were recorded. Those in the CD-intervention group also reported how many times they had practiced the techniques. The study employed a randomized controlled trial. Results show that the CD-intervention group had a significantly better score on total Wellbeing, as measured by the ESAS (0-10) Edmonton Scale. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The aim of this study was to determine the effects of estrogen therapy (ET) on carotid artery inflammation when initiated early and late relative to surgical menopause. Female cynomolgus macaques consuming atherogenic diets were ovariectomized and randomized to control or oral estradiol (E2; human equivalent dose of 1 mg/d micronized E2) initiated at 1 month (early menopause, n = 24) or 54 months (late menopause, n = 40) after ovariectomy. The treatment period was 8 months. Carotid artery expression of the markers of monocyte/macrophages (CD68 and CD163), dendritic cells (CD83), natural killer cells (neural cell adhesion molecule-1), and interferon-γ was significantly lower in E2-treated animals in the early menopause group but not in the late menopause group (P menopausal stage (P menopause inhibits macrophage accumulation in the carotid artery, an effect that is not observed when E2 is administered after several years of estrogen deficiency. No evidence for pro-inflammatory effects of late ET is observed. The results provide support for the timing hypothesis of postmenopausal ET with implications for the interpretation of outcomes in the Women's Health Initiative.

    Hyperglycaemia blocks sevoflurane-induced postconditioning, and cardioprotection in hyperglycaemic myocardium can be restored by inhibition of the mitochondrial permeability transition pore (mPTP). We investigated whether sevoflurane-induced postconditioning is also blocked in the prediabetic heart and if so, whether cardioprotection could be restored by inhibiting mPTP. Zucker lean (ZL) and Zucker obese (ZO) rats were assigned to one of seven groups. Animals underwent 25 min of ischaemia and 120 min of reperfusion. Control (ZL-/ZO Con) animals were not further treated. postconditioning groups (ZL-/ZO Sevo-post) received sevoflurane for 5 min starting 1min prior to the onset of reperfusion. The mPTP inhibitor cyclosporine A (CsA) was administered intravenously in a concentration of 5 (ZO CsA and ZO CsA+Sevo-post) or 10 mg/kg (ZO CsA10+Sevo-post) 5 min before the onset of reperfusion. At the end of reperfusion, infarct sizes were measured by TTC staining. Blood samples were collected to measure plasma levels of insulin, cholesterol and triglycerides. Sevoflurane postconditioning reduced infarct size in ZL rats to 35±12% (pfailed to restore cardioprotection in the prediabetic but normoglycaemic heart of Zucker obese rats in vivo.

    Compare vasopressin, amiodarone, and epinephrine administration by sternal intraosseous (SIO), tibial intraosseous (TIO), and intravenous (IV) routes in a swine model of cardiac arrest. Prospective, randomized, between subjects, experimental design. Laboratory. Male Yorkshire-cross swine (N = 35), seven per group. Swine were randomized to SIO, TIO, IV, cardiopulmonary resuscitation (CPR) with defibrillation, or CPR-only groups. Ventricular fibrillation (VF) was induced under general anesthesia. Mechanical CPR began 2 minutes postarrest. Vasopressin (40 U) was administered to the SIO, TIO, and IV groups 4 minutes postarrest. Defibrillation was performed and amiodarone (300 mg) was administered 6 minutes postarrest. Defibrillation was repeated, and epinephrine (1 mg) was administered 10 minutes postarrest. Defibrillation was repeated every 2 minutes and epinephrine repeated every 4 minutes until return of spontaneous circulation (ROSC) or 26 postarrest minutes elapsed. Rate of ROSC, time to ROSC, and odds of ROSC. There were no significant differences in rate of ROSC between the SIO and TIO (p = 0.22) or IV groups (p = 1.0). Time to ROSC was five times less in the SIO group than the TIO group (p = 0.003) but not compared to IV (p = 0.125). Time to ROSC in the IV group was significantly less than the TIO group (p = 0.04). Odds of ROSC for the SIO group were five times higher compared to the TIO group but same as IV. Odds of ROSC in the IV group were higher than the TIO group. There was a statistically significant delay in the time to ROSC and a clinically significant difference in odds of ROSC when resuscitative drugs, including lipophilic amiodarone, were administered by the TIO route compared to the SIO and IV routes in a swine model of sudden cardiac arrest. Further investigations are warranted to isolate the mechanism behind these findings.

    1990-12-01

    Group dynamics play a significant role within any organization, culture, or unit. The important thing to remember with any of these structures is that they are made up of people--people with different ideas, motivations, background, and sometimes different agendas. Most groups, formal or informal, look for a leader in an effort to maintain cohesiveness of the unit. At times, that cultural bond must be developed; once developed, it must be nurtured. There are also times that one of the group no longer finds the culture comfortable and begins to act out behaviorally. It is these times that become trying for the leader as she or he attempts to remain objective when that which was once in the building phase of group cohesiveness starts to fall apart. At all times, the manager must continue to view the employee creating the disturbance as an integral part of the group. It is at this time that it is beneficial to perceive the employee exhibiting problem behaviors as a special employee, as one who needs the benefit of your experience and skills, as one who is still part of the group. It is also during this time that the manager should focus upon her or his own views in the area of power, communication, and the corporate culture of the unit that one has established before attempting to understand another's point of view. Once we understand our own motivation and accept ourselves, it is then that we may move on to offer assistance to another. Once we understand our insecurities recognizing staff dysfunction as a symptom of system dysfunction will not be so threatening to the concept of the manager that we perceive ourselves to be. It takes a secure person to admit that she or he favors staff before deciding to do something to change things. The important thing to know is that it can be done. The favored staff can find a new way of relating to others, the special employee can find new modes of behavior (and even find self-esteem in the process), the group can find new ways

    There is currently little evidence on effective interventions for poststroke apraxia of speech. We report outcomes of a trial of self-administered computer therapy for apraxia of speech. Effects of speech intervention on naming and repetition of treated and untreated words were compared with those of a visuospatial sham program. The study used a parallel-group, 2-period, crossover design, with participants receiving 2 interventions. Fifty participants with chronic and stable apraxia of speech were randomly allocated to 1 of 2 order conditions: speech-first condition versus sham-first condition. Period 1 design was equivalent to a randomized controlled trial. We report results for this period and profile the effect of the period 2 crossover. Period 1 results revealed significant improvement in naming and repetition only in the speech-first group. The sham-first group displayed improvement in speech production after speech intervention in period 2. Significant improvement of treated words was found in both naming and repetition, with little generalization to structurally similar and dissimilar untreated words. Speech gains were largely maintained after withdrawal of intervention. There was a significant relationship between treatment dose and response. However, average self-administered dose was modest for both groups. Future software design would benefit from incorporation of social and gaming components to boost motivation. Single-word production can be improved in chronic apraxia of speech with behavioral intervention. Self-administered computerized therapy is a promising method for delivering high-intensity speech/language rehabilitation. URL: http://orcid.org/0000-0002-1278-0601.

    Full Text Available Objective: To investigate the effects of coconut water intake on lipid profile and atherogenic predictor indices of albino rabbits overdosed with paracetamol using standard methods. Methods: Thirty-five albino rabbits weighing between 800–1200 g and aged between 2 and 3 months, were divided into 7 groups (I–VII of 5 animals each. Groups I, II and III were orally administered distilled water (20 mL/kg body weight, coconut water (20 mL/kg body weight and paracetamol (1000 mg/kg body weight respectively, for 7 days. Groups IV and V were administered coconut water (20 mL/kg body weight and silymarin (35 mg/kg body weight, respectively, for 6 days, then paracetamol (1000 mg/kg body weight on the 7th day. Groups VI and VII were administered distilled water for 6 days, paracetamol on the 7th day, then coconut water and silymarin, respectively, after 3 h. Results: The results showed that paracetamol overdose significantly reduced (P < 0.05 the mean body weight of the animals, increased the concentrations of serum total cholesterol, triacylglycerol, very low density lipoprotein cholesterol, low density lipoprotein cholesterol and the atherogenic predictor indices but reduced the serum high density lipoprotein cholesterol concentration of the animals relative to the control. The observed changes in the lipid profile and atherogenic predictor indices were countered more by post- than pre-treatment with coconut water and silymarin. Conclusions: The results indicated that coconut water acted as an effective antidote to paracetamol overdose-induced lipid abnormality in animals.

    The primary objective of this study was to assess the effect of aromatherapy and classic massage administered in various ways to breast cancer patients on their symptoms and quality of life. The sampling consisted of 280 patients. Quality of life and symptoms of the patients were evaluated once at baseline and then at week 6 and week 10 following the intervention. After intervention, the control group was observed to have lower total quality of life score and subdomain scores, whereas fragrance, massage and aromatherapy massage groups had higher scores, and the increase was more obvious particularly in the patients in the aromatherapy massage group. Similarly, whereas psychological and physical symptoms were experienced more intensely in the control group, the severity of all the symptoms experienced by the other patients decreased at week 6 and week 10 as compared with baseline especially in the group that was administered massage with aromatherapy. © 2013 Wiley Publishing Asia Pty Ltd.

    Obesity and tobacco smoking represent the largest challenges to public health, but the causal relationship between nicotine and obesity is poorly understood. Nicotine suppresses body weight gain, a factor impacting smoking initiation and the failure to quit, particularly among obese smokers. The impact of nicotine on body weight regulation in obesity-prone and obesity-resistant populations consuming densely caloric diets is unknown. In the current experiment, body weight gain of adult male rats maintained on a high energy diet (31.8% kcal from fat) distributed into obesity-prone (OP), obesity-resistant (OR) and an intermediate group, which was placed on standard rodent chow (Chow). These rats were surgically implanted with intravenous catheters and allowed to self-administer nicotine (0 or 60μg/kg/infusion, a standard self-administration dose) in 1-h sessions for 20 consecutive days. Self-administered nicotine significantly suppressed body weight gain but not food intake in OP and Chow rats. Self-administered nicotine had no effect on body weight gain in OR rats. These data suggest that: 1) OR rats are also resistant to nicotine-induced suppression of body weight gain; and 2) nicotine may reduce levels of obesity in a subset of smokers prone to obesity.

    To assess the clinical and work productivity effects of a brief intervention using telephone-administered cognitive-behavioral therapy (CBT) for clients with depressive symptoms attending an employee assistance program (EAP). Self-referred clients attending the PPC Canada EAP with clinically relevant depressive symptoms at initial assessment were offered an 8-session telephone-administered CBT program. Outcomes before and after intervention were assessed with the 9-item Personal Health Questionnaire (PHQ-9), Global Assessment of Functioning (GAF), and clinician ratings of work absence and performance impairment. Fifty clients were referred to the pilot program; 39 participated and 31 completed the telephone CBT program. Among program participants, there was significant improvement in PHQ-9 and GAF scores. There was also a significant reduction in performance impairment but not work absence. Anecdotal reports indicated high satisfaction ratings among participants. The results of this pilot study, although limited by the absence of a comparison or control group, suggest that a brief telephone-administered CBT program can improve depressive symptomatology, work productivity, and general function in depressed clients attending an EAP. Further controlled studies are needed to confirm these preliminary findings.

    Full text: In his review 'Genesis of Unified Gauge Theories' at the symposium in Honour of Abdus Salam (June, page 23), Tom Kibble of Imperial College, London, looked back to the physics events around Salam from 1959-67. He described how, in the early 1960s, people were pushing to enlarge the symmetry of strong interactions beyond the SU(2) of isospin and incorporate the additional strangeness quantum number. Kibble wrote - 'Salam had students working on every conceivable symmetry group. One of these was Yuval Ne'eman, who had the good fortune and/or prescience to work on SU(3). From that work, and of course from the independent work of Murray Gell- Mann, stemmed the Eightfold Way, with its triumphant vindication in the discovery of the omega-minus in 1964.' Yuval Ne'eman writes - 'I was the Defence Attaché at the Israeli Embassy in London and was admitted by Salam as a part-time graduate student when I arrived in 1958. I started research after resigning from the Embassy in May 1960. Salam suggested a problem: provide vector mesons with mass - the problem which was eventually solved by Higgs, Guralnik, Kibble,.... (as described by Kibble in his article). I explained to Salam that I had become interested in symmetry. Nobody at Imperial College at the time, other than Salam himself, was doing anything in groups, and attention further afield was focused on the rotation - SO(N) - groups. Reacting to my own half-baked schemes, Salam told me to forget about the rotation groups he taught us, and study group theory in depth, directing me to Eugene Dynkin's classification of Lie subalgebras, about which he had heard from Morton Hamermesh. I found Dynkin incomprehensible without first learning about Lie algebras from Henri Cartan's thesis, which luckily had been reproduced by Dynkin in his 1946 thesis, using his diagram method. From a copy of a translation of Dynkin's thesis which I found in the British Museum Library, I

    Objective The Global Physical Activity Questionnaire (GPAQ) was originally designed to be interviewer-administered by the World Health Organization in assessing physical activity. The main aim of this study was to compare the psychometric properties of a self-administered GPAQ with the original interviewer-administered approach. Additionally, this study explored whether using different accelerometry-based physical activity bout definitions might affect the questionnaire’s validity. Methods A total of 110 participants were recruited and randomly allocated to an interviewer- (n = 56) or a self-administered (n = 54) group for test-retest reliability, of which 108 participants who met the wear time criteria were included in the validity study. Reliability was assessed by administration of questionnaires twice with a one-week interval. Criterion validity was assessed by comparing against seven-day accelerometer measures. Two definitions for accelerometry-data scoring were employed: (1) total-min of activity, and (2) 10-min bout. Results Participants had similar baseline characteristics in both administration groups and no significant difference was found between the two formats in terms of validity (correlations between the GPAQ and accelerometer). For validity, the GPAQ demonstrated fair-to-moderate correlations for moderate-to-vigorous physical activity (MVPA) for self-administration (r s = 0.30) and interviewer-administration (r s = 0.46). Findings were similar when considering 10-min activity bouts in the accelerometer analysis for MVPA (r s = 0.29 vs. 0.42 for self vs. interviewer). Within each mode of administration, the strongest correlations were observed for vigorous-intensity activity. However, Bland-Altman plots illustrated bias toward overestimation for higher levels of MVPA, vigorous- and moderate-intensity activities, and underestimation for lower levels of these measures. Reliability for MVPA revealed moderate correlations (r s = 0.61 vs. 0.63 for self

    A method based on the construction of an image quality discriminant function is proposed. The parameters which characterise it are selected among the typical ones measured in a Tc 99m - HMPAO cerebral blood flow SPECT. The results are compared among groups of patient's studies who received different activity (430, 640 and 807 MBq), looking for the minimum that guaranty good image quality. A reduction in the administered 99m Tc-HMPAO activity to the patient down to 430 MBq was possible without affecting the tomographic image quality. The labelling yield was the main parameter that determined the image quality. (author)

    The Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5; American Psychiatric Association [APA], 2013) includes Other- and Unspecified- Trauma and Stressor-Related Disorders to capture subthreshold Posttraumatic Stress Disorder (PTSD) symptoms. However, the DSM-5 does not specify the number or type of symptoms needed to assign them. The purpose of the current study was to extend our understanding of subthreshold PTSD by comparing four commonly used definitions adapted to the DSM-5 PTSD criteria in an outpatient treatment-seeking sample. Veterans (N = 193) presenting to PTSD clinics were assessed using the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). Participants reported a criterion A traumatic event, but did not meet criteria for threshold-PTSD. We hypothesized that the number of veterans captured would be highest when fewer specific criterion sets were required by the subthreshold definition. Our hypothesis was upheld in that the more criteria required by the subthreshold PTSD definition, the lower the number of veterans counted within the group. The study consisted primarily of trauma treatment-seeking male veterans, with chronic PTSD symptoms. In addition, the sample size was small and was collected as part of routine clinical care. These results support previous contentions around careful decision making when defining what constitutes subthreshold PTSD in research and clinical work. It also points to the need for continued research to better understand the diagnostic and treatment implications of subthreshold PTSD. Published by Elsevier B.V.

    Tendinitis affects a substantial number of people in several occupations involving repetitive work or direct trauma. Iontophoresis is a therapeutic alternative used in the treatment of injury during the inflammatory phase. In recent years, gold nanoparticles (GNP) have been studied due to their therapeutic anti-inflammatory capacity and as an alternative to the transport of several proteins. This study evaluates the therapeutic effects of iontophoresis using GNPs and diclofenac diethylammonium on inflammatory parameters in rats challenged with traumatic tendinitis. Wistar rats were divided in three treatment groups (n = 15): (1) iontophoresis + diclofenac diethylammonium; (2) iontophoresis + GNP; and (3) iontophoresis + diclofenac diethylammonium + GNP. External control was formed by challenged tendons without treatment (n = 15). Iontophoresis was administered using 0.3 mA direct current on 1.5 cm(2) electrodes. The levels of both inflammatory cytokines were significantly higher in untreated challenged rats, when compared with the control (5.398 ± 234 for interleukin 1 beta and 6.411 ± 432 for tumor necrosis factor alpha), which confirms the occurrence of an inflammatory stage in injury (P diclofenac and GNP, results were similar to the control (1.732 ± 239) (P diclofenac and GNPs presented decreased levels, compared with the control (3.221 ± 369) (P < 0.05). The results show the efficacy of drug administration using direct current to treat tendinitis in an animal model, and the potential anti-inflammatory, carrier, and enhancing effects of GNPs in iontophoresis.

    Full Text Available The efficacy of orally administered powdered aloe juice (Aloe ferox was evaluated against ticks on cattle and against ticks and fleas on dogs. Twelve calves were each infested over a 25-day period with approximately 4000 larvae of Rhipicephalus (Boophilus decoloratus and allocated to 3 groups of 4 calves each. Three days after the last larval infestation and daily for 22 days thereafter, the calves in 1 group were fed 5 mg / kg body weight and those in another 25 mg / kg body weight of powdered aloe juice incorporated in game maintenance pellets, while the animals in the 3rd group received only pellets. Detached female ticks were collected daily and counted and the weights and the fertility of groups of 50 engorged female ticks collected from the animals were ascertained. The powdered aloe juice in the game maintenance pellets had no effect on the tick burdens of the calves or on the fertility of the ticks. Six dogs, in each of 2 groups, were treated daily for 15 consecutive days, commencing on Day -5 before the 1st tick infestation, with either 0.39 g or 0.74 g of powdered aloe juice, administered orally in gelatin capsules, while a 3rd group of 6 dogs served as untreated controls. All the dogs were challenged with Haemaphysalis leachi on Days 0 and +7, and with Ctenocephalides felis on Days+1and +8, and efficacy assessments were made 1 day after flea and 2 days after tick challenge, respectively. Treatment was not effective against ticks or fleas on the dogs.

    Full Text Available Characterizing the variability in transcript levels across breeds and sex in swine for genes that play a role in drug metabolism may shed light on breed and sex differences in drug metabolism. The objective of the study is to determine if there is heterogeneity between swine breeds and sex in transcript levels for genes previously shown to play a role in drug metabolism for animals administered flunixin meglumine or fenbendazole. Crossbred nursery female and castrated male pigs (n = 169 spread across 5 groups were utilized. Sires (n = 15 of the pigs were purebred Duroc, Landrace, Yorkshire or Hampshire boars mated to a common sow population. Animals were randomly placed into the following treatments: no drug (control, flunixin meglumine, or fenbendazole. One hour after the second dosing, animals were sacrificed and liver samples collected. Quantitative Real-Time PCR was used to measure liver gene expression of the following genes: SULT1A1, ABCB1, CYP1A2, CYP2E1, CYP3A22 and CYP3A29. The control animals were used to investigate baseline transcript level differences across breed and sex. Post drug administration transcript differences across breed and sex were investigated by comparing animals administered the drug to the controls. Contrasts to determine fold change were constructed from a model that included fixed and random effects within each drug. Significant (P-value <0.007 basal transcript differences were found across breeds for SULT1A1, CYP3A29 and CYP3A22. Across drugs, significant (P-value <0.0038 transcript differences existed between animals given a drug and controls across breeds and sex for ABCB1, PS and CYP1A2. Significant (P <0.0038 transcript differences across breeds were found for CYP2E1 and SULT1A1 for flunixin meglumine and fenbendazole, respectively. The current analysis found transcript level differences across swine breeds and sex for multiple genes, which provides greater insight into the relationship between flunixin

    Full text: Rare earths are used in high technology field, however, the information on their biological effects are not sufficient. The behaviour of rare earths in biology is of interest in connection with their toxicity. In the present study, the distribution of rare earths in liver of mice administered with these elements was investigated. The effects on Ca and other biological essential elements were also determined. Male mice (5 weeks old) were injected with one of 12 kinds of rare earths (chlorides of Y, La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and Yb) at the dose of 25 mg/KXg body weight. After 20 hours of administration, mice were sacrificed, then liver and other organs were taken out. Liver was homogenized and separated by centrifugation. The concentrations of rare earths administered were measured by microwave-induced plasma-mass spectrometry (MIP-MS) after acid digestion. The concentrations of administered elements in whole liver were about 100μg/g (wet weight), where the difference between elements was few. Distribution amounts of elements administered in four fractions were following order; 700μg precipitate > mitocondrial fraction > microsomal fraction > cytosol. The relative contents in these fractions, however, was different depending on the element administered. Calcium concentrations in liver of administered mice were higher than those of control mice. Increase of Ca concentrations were observed in all four fractions and the increase ratio was also dependent on the elements administered

  9. Group Empowerment in Nursing Education.

    Nursing education is experiencing rapid changes, as nurses are expected to transform and lead health care delivery within the United States. The ability to produce exceptional graduates requires faculty who are empowered to achieve goals. The Sieloff-King Assessment of Group Empowerment Within Organizations (SKAGEO) was adapted and administered online to a stratified sample of administrators and faculty in American Association of Colleges of Nursing-member schools. Participants' scores were within high ranges in both empowerment capacity and capability; however, administrator group scores were higher. Data analyses indicated that administrator leadership competencies were associated with group empowerment. This study suggests that empowered faculty and administrator groups anticipate changing health care trends and effect student outcomes and competencies by their interventions. Also, it can be inferred that as a result of administrators' competencies, participants teach in empowered work environments where they can model ideal behaviors. Copyright 2015, SLACK Incorporated.

    The aim of this research was to check the effect of the prenatally administered β-hydroxy β-methylbutyrate (HMB) on the development of enamel surface of the spiny mice offspring. The spiny mice dams were randomly assigned into three groups: control group (not supplemented with HMB) and two experimental groups in which powdered HMB was given at the daily dosage of 0.2g/kg of body weight (group I) and 0.02g/kg of body weight (group II) during the last period of gestation. Newborn pups were euthanized by CO 2 inhalation. The morphology of incisor teeth was analysed using atomic force microscopy (AFM) in semi-contact mode in the height, magnitude and phase domains. Height images became a basis for determination of surface roughness parameters. Conducted study indicated that maternal HMB administration markedly influences enamel development. Enamel of offspring's teeth in both experimental groups was characterized by significantly smaller values of indices describing surface roughness and profile. HMB supplementation influenced the calculated parameters regardless of the diet type and offspring sex, however higher dose of HMB caused stronger changes in enamel surface's physical properties and could be observed in higher intensity in the male group. HMB administration caused reduction in the irregularities of enamel surface, thereby possibly reducing the probability of bacteria adhesion and caries development. These observations may serve to improve nutrition and supplementation of animals and could be a lead for further research. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The present study aims to develop a self-administered dementia checklist to enable community-residing older adults to realize their declining functions and start using necessary services. A previous study confirmed the factorial validity and internal reliability of the checklist. The present study examined its concurrent validity and discriminant validity. The authors conducted a 3-step study (a self-administered survey including the checklist, interviews by nurses, and interviews by doctors and psychologists) of 7,682 community-residing individuals who were over 65 years of age. The authors calculated Spearman's correlation coefficients between the scores of the checklist and the results of a psychological test to examine the concurrent validity. They also compared the average total scores of the checklist between groups with different Clinical Dementia Rating (CDR) scores to examine discriminant validity and conducted a receiver operating characteristic analysis to examine the discriminative power for dementia. The authors analyzed the data of 131 respondents who completed all 3 steps. The checklist scores were significantly correlated with the respondents' Mini-Mental State Examination and Frontal Assessment Battery scores. The checklist also significantly discriminated the patients with dementia (CDR = 1+) from those without dementia (CDR = 0 or 0.5). The optimal cut-off point for the two groups was 17/18 (sensitivity, 72.0%; specificity, 69.2%; positive predictive value, 69.2%; negative predictive value, 72.0%). This study confirmed the concurrent validity and discriminant validity of the self-administered dementia checklist. However, due to its insufficient discriminative power as a screening tool for older people with declining cognitive functions, the checklist is only recommended as an educational and public awareness tool.

    Full Text Available Background. Osteoarthritis (OA is more prevalent in women, particularly after menopausal age. Women are more likely to seek complementary and alternative medicine (CAM approaches. We examined the feasibility of training self-administered acupressure exercise and assessed its impact on OA symptoms among women with knee OA. Methods. Thirty-six eligible postmenopausal women were randomly assigned in the acupressure exercise group (n=15 or the control group (n=21 for 12 weeks. Feasibility outcomes (e.g., compliance and adverse effects and clinical outcomes (e.g., pain, stiffness, and physical function were assessed. Data were collected at baseline, 6 weeks and 12 weeks. Both per-protocol and intention-to-treat analysis were employed. Results. The training materials were well received. The feedback from participants suggests that self-administered acupressure exercise is easy to learn and safe to perform at home, although no statistically significant results of the clinical outcome were observed. Our findings didn’t reveal superiority or inferiority of acupressure compared with usual care. Conclusion. Acupressure exercise is feasible to be trained among postmenopausal women with knee osteoarthritis. Due to the limitations of this study such as small sample size and high attrition rate, acupressure’s efficacy needs to be further explored in larger scale studies with more rigorous design.

    In the manual for the California Verbal Learning Test - II (CVLT-II), the authors suggest that nonverbal, rather than verbal, tasks be administered during the delay interval between administrations of the Short- and Long-Delay Recall trials of this test. They contend that this method minimizes the retroactive interference produced by intervening tasks. The purpose of the current study was to compare the extent to which verbal and nonverbal intervening tasks produce retroactive interference on CVLT-II List A recall following the long-delay. Participants in the present study were 120 undergraduate students. All participants completed the CVLT-II, and were randomly assigned to a group in which they were administered either a verbal (WAIS-III Vocabulary or Peabody Picture Vocabulary Test - IIIB) or nonverbal (Raven's Standard Progressive Matrices or WAIS-III Block Design) intervening task during the long-delay interval of the CVLT-II. Statistical analyses revealed that regardless of the type of intervening task given, participants in all groups recalled the same number of words and produced a similar number of intrusions during the CVLT-II recall trials. This indicates that not all verbal tasks produce retroactive effects beyond those produced by nonverbal tasks.

    We studied the effects of exogenously administered recombinant murine interleukin (IL)-10 on the development of experimental autoimmune orchitis (EAO) in C3H/He mice. IL-10 significantly augments histological signs of EAO when administered for 6 consecutive days from days 15 to 20 after primary...... immunisations with testicular germ cells. These data demonstrate that IL-10, in addition to its well-known antiinflammatory property, also has proinflammatory functions capable of up-regulating testicular immunoinflammatory processes in vivo....

    Full Text Available Objective: To analyze K-ras gene from induced pancreatic cancer rats administered with Momordicacharantia and Ocimumbasilicum leaf extracts. Methods: Twenty-five (25 adult rats weighing between 90–120 g were divided into 5 groups namely RA, RB, RC, NC and PC, each group had 5 rats. The PC which served as the control was fed with normal fish meal and water ad libitum; the NC which is the negative control received 20 mg/ml/week of Nitrosamines only while other groups received different concentrations of aqueous extract of both M. charantia and O. basilicum (200 mg, 100 mg, 50 mg and Nitrosamine. Qualitative phytochemical screening of the aqueous extract of both M. charantia and O. basilicum was carried out. The extraction of DNA was done using Jena Bioscience DNA preparation kit and the protocol was based on the spin column based genomic DNA purification from blood, animal and plant cells. Agarose gel electrophoresis was used to analyze the K-ras gene extracted from the pancreas tissues of experimental rats while hematoxylinand eosin staining was used for histological assay. Results: Phytochemical screening revealed the presence of alkaloids, tannins, flavonoids, saponins and glycosides in M. charantia while saponins, tannins and glycosides were discovered in O. basilicum. Significant reduction in the weight of rats treated with 200 mg of aqueous extracts of M. charantia and O. basilicum while rats that were dosed with nitrosamines only showed a slight increase in weight in the first three weeks when compared to the positive control. Histological studies revealed that there is both enlargement and reduction in the islet cell size, with one of the sections showing a normal islet cell size. While the agarose gel electrophoresis revealed that there may be possibility of prevention of damage to k-ras gene as a result of the effect of plants extract. Conclusion: This work has shown that the leaf extracts of both M. charantia and O. basilicum

    We examined the acute toxicity of depleted uranium (DU) after subcutaneous injection as a simulated wounds model, and the effects of the chelating agent catechol-3,6-bis(methyliminodiacetic acid) (CBMIDA), by local treatment in rats. First, to examine the initial behavior and toxicity of uranium of different chemical forms, male Wistar rats were subcutaneously injected with 4 and 16 mg/kg DU (pH 1) in a solution of pH 1 and 7, respectively, and were killed 1, 3, 6 and 24 hours later. After the injection of DU(pH1), about 60% of the uranium was retained for first 1-3 hours at the injected sites, and then decreased to 16% at 24 hours in the 4 mg/kg DU group; however, the uranium did not change significantly in the 16 mg/kg DU group. Urinary excretion rates of uranium increased in a time-independent manner after the injection Depositions of uranium in the liver, kidneys and femur were found at 1 hour after DU injection, with significant increases in serum and urinary biochemical markers indicating acute and severe damage. The results of the DU (pH 7) injection were useful for estimating the toxicity of uranium by the chemical changes in the body. Second, CBMIDA (480 mg/kg) was infused into the DU-injected site at 0, 10, 30, 60 min and 24 hours after the subcutaneous injection of 4 mg/kg DU (pH 1 and 7). When CBMIDA was administered within 120 min after DU (pH 1) injection, the uranium at the injected sites decreased to 4-17% of that in the no-treatment DU (pH 1) group, and was excreted effectively in the urine and feces, with decreased levels in the kidneys and femur. The results indicated that the subcutaneously injected uranium acutely induced severe damage in the DU-injected sites and organs after DU intake, relating to chemical forms of uranium by pH and that local treatment of CBMIDA was effective in decreasing the acute toxicity of uranium if carried out as early as possible (at least within 2 hours) after DU administration.

    The present investigation sought to determine whether a self-administered questionnaire could be used to obtain occupational information from pregnant women attending the obstetrical clinics at the University of California, San Francisco from July to November 1986. The authors compared the accuracy of responses of 57 women on the self-administered questionnaire with those obtained on a detailed clinical interview by an occupational health professional. The self-administered questionnaire and the clinical interview included information on the woman's job title, the type of company she worked for, the level of physical activity, her exposures on the job and at home, and her partner's occupation. The authors also examined whether the validity of the self-administered questionnaire could be improved on review by an industrial hygienist. The questionnaire took less than 20 minutes to complete, with over 90% of the women answering three-quarters of it. It was substantially accurate in obtaining information on number of hours worked during pregnancy, type of shift worked, and stress level in the workplace; exposure to radiation, video display terminals, fumes, gases, and cigarette smoke in the workplace; and exposure to pesticides, paint, and cigarette smoke at home. On those variables for which the responses on the self-administered questionnaire were less accurate, review by the industrial hygienist improved the level of accuracy considerably. These findings suggest that a self-administered questionnaire can be used to obtain valid information from pregnant women attending a prenatal clinic

    In the European Union, various fluoroquinolones are authorised for the treatment of food producing animals. Each administration poses an increased risk of development and spread of antimicrobial resistance. The aim of this study was to investigate the impact of parenteral administration of enrofloxacin on the prevalence of enrofloxacin and ciprofloxacin susceptibilities in the commensal intestinal E. coli population. E. coli isolates from faeces of twelve healthy pigs were included. Six pigs were administered enrofloxacin on day 1 to 3 and after two weeks for further three days. The other pigs formed the control group. MIC values were determined. Virulence and resistance genes were detected by PCR. Phylogenetic grouping was performed by PCR. Enrofloxacin and ciprofloxacin were analysed in sedimentation samples by HPLC. Susceptibility shifts in commensal E. coli isolates were determined in both groups. Non-wildtype E. coli could be cultivated from two animals of the experimental group for the first time one week after the first administration and from one animal of the control group on day 28. The environmental load with enrofloxacin in sedimentation samples showed the highest amount between days one and five. The repeated parenteral administration of enrofloxacin to pigs resulted in rapidly increased MIC values (day 28: MIC up to 4 mg/L, day 35: MIC ≥ 32mg/L). E. coli populations of the control group in the same stable without direct contact to the experimental group were affected. The parenteral administration of enrofloxacin to piglets considerably reduced the number of the susceptible intestinal E. coli population which was replaced by E. coli strains with increased MIC values against enrofloxacin. Subsequently also pigs of the control were affected suggesting a transferability of strains from the experimental group through the environment to the control group especially as we could isolate the same PFGE strains from both pig groups and the environment.

    Artemether (AM) is an antimalarial drug derived from artemisinin (Qinghaosu), an extract of the herb Artemisia annua L., sweet wormwood. Its antiparasitic effect is that of a schizontocide and is explained by rapid uptake by parasitized erythrocytes and interaction with a component of hemoglobin degradation resulting in formation of free radicals. It has been shown to exhibit a high clinical cure rate. Previous animal safety studies with Qinghaosu derivatives revealed dose-dependent neurotoxicity with movement disturbances and neuropathic changes in the hindbrain of intramuscularly treated dogs, rats and monkeys. Such effects have not been seen in man. The objective of our present studies was to compare the effects of high levels of AM administered to dogs p.o. versus i.m. In a pilot study 20 mg/kg/day of AM was given i.m. to groups of 3 male Beagle dogs for 5 and 30 days, respectively. Clinical signs of neurotoxicity were noted in some individual dogs from test day 23 on. One dog had to be sacrificed pre-term. Hematologic findings indicated a hypochromic, microcytic anemia. Microscopic examination demonstrated neuropathic changes only at 30 days, but not at 5 days. The animals had neuronal and secondary axonal damage, most prominent in the cerebellar roof, pontine and vestibular nuclei, and in the raphe/paralemniscal region. The affected neurons showed loss of Nissl substance, cytoplasmic eosinophilia, shrinkage of the nucleus and in advanced stages scavenging by microglia. In a subsequent experiment, AM was administered to groups of 4 male and 4 female dogs, respectively, at 8 daily doses of 0, 20, 40 and 80 mg/kg i.m., or 0, 50, 150 and 600 mg/kg p.o. Neurologic signs were seen at high i.m. doses only. In most animals they were inconspicuous and consisted of reduced activity with convulsions seen in single dogs shortly before death. Neuronal damage occurred in all animals at 40 and 80 mg/kg following i.m. treatment. At 20 mg/kg minimal effects occurred in 5

    Isoproterenol-induced salivary polypeptides (IISP), a group of proline-rich proteins synthesized by mouse parotids, have been considered as markers for isoproterenol-induced parotid hypertrophy. Rodents fed diets containing high-tannin cereals (sorghum), also develop parotid hypertrophy. To test whether tannins are directly involved in provoking sialotrophic growth, we studied the effect of intraperitoneal and topical oral administrations of tannic acid (TA) on the induction of IISP polypeptides in endogamic mice (A/Snell). TA was characterized by HPLC chromatography and spectral analysis and shown to be composed solely of gallotannins, a complex family of glucose and gallic acid esters. IISP polypeptides were monitored in saliva by SDS-polyacrylamide gel electrophoresis during 36 h after ending TA stimulation. Single daily intraperitoneal administrations of TA for 3 consecutive days (0.033 mg/g bw/day), at variance of parallel administrations of isoproterenol (0.042 mg/g bw/day) failed to induce IISP polypeptides. However, repeated topical applications of TA into the mouse mouths (1.21 mg/g bw divided into three equal doses given at 4-h intervals within a single day) resulted in unequivocal induction of IISP polypeptides. That response was clearly intensified by increasing the stimulation frequency to eight equivalent doses given at 1.5-h intervals within a single day (corresponding to 3.23 mg/g bw) and even further by repeating this protocol for 3 days. Under these productive schemes of stimulations by TA, electrophoretic fractionation of parotid homogenates showed new polypeptide bands migrating in parallel to salivary IISP. These results suggest that topically administered gallotannins are effective inducers of trophic growth in mouse parotids.

    Take-home naloxone (THN) programs have been operating in Australia since 2012 in a variety of settings. We examine whether THN programs were effective in increasing knowledge about opioid overdose and appropriate responses in program participants. Data were obtained from pre- and post-training questionnaires administered as part of the early evaluations of THN naloxone programs operated in Sydney (n = 67), Melbourne (n = 280), Perth (n = 153) and Canberra (n = 183). Pooled data from comparable items, analysed in the domains specified in previously-developed evaluation scales, were compared using repeated-measures analysis of variance and random effects logistic regression. Results pre- and post-training were compared as well as results across sites. High levels of knowledge about overdose risks and signs and appropriate actions to take were observed at baseline and this generally improved over time. No substantial differences were identified across cities. Knowledge also increased with participant age but the improvements over time were similar in each age group. There were small differences by participant gender with knowledge generally higher among females. THN programs are effective in improving knowledge related to overdose response. Major improvements in knowledge were limited to overdose recognition and effect of naloxone suggesting that education may best be focused on overdose signs and the use of naloxone among populations accessed through these programs. A focus on younger people also appears warranted. Further work is needed to understand the impact of training and knowledge on actual behaviours around overdose events. © 2018 Australasian Professional Society on Alcohol and other Drugs.

    Previous work from our group has shown that intranasal MSC-treatment decreases lesion volume and improves motor and cognitive behavior after hypoxic-ischemic (HI) brain damage in neonatal mice. Our aim was to determine the kinetics of MSC migration after intranasal administration, and the early effects of MSCs on neurogenic processes and gliosis at the lesion site. HI brain injury was induced in 9-day-old mice and MSCs were administered intranasally at 10days post-HI. The kinetics of MSC migration were investigated by immunofluorescence and MRI analysis. BDNF and NGF gene expression was determined by qPCR analysis following MSC co-culture with HI brain extract. Nestin, Doublecortin, NeuN, GFAP, Iba-1 and M1/M2 phenotypic expression was assessed over time. MRI and immunohistochemistry analyses showed that MSCs reach the lesion site already within 2h after intranasal administration. At 12h after administration the number of MSCs at the lesion site peaks and decreases significantly at 72h. The number of DCX(+) cells increased 1 to 3days after MSC administration in the SVZ. At the lesion, GFAP(+)/nestin(+) and DCX(+) expression increased 3 to 5days after MSC-treatment. The number of NeuN(+) cells increased within 5days, leading to a dramatic regeneration of the somatosensory cortex and hippocampus at 18days after intranasal MSC administration. Interestingly, MSCs expressed significantly more BDNF gene when exposed to HI brain extract in vitro. Furthermore, MSC-treatment resulted in the resolution of the glial scar surrounding the lesion, represented by a decrease in reactive astrocytes and microglia and polarization of microglia towards the M2 phenotype. In view of the current lack of therapeutic strategies, we propose that intranasal MSC administration is a powerful therapeutic option through its functional repair of the lesion represented by regeneration of the cortical and hippocampal structure and decrease of gliosis.

    Objective Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that can affect the central nervous system in multiple ways, including causing cognitive dysfunction. Cognitive dysfunction is a common complaint of SLE patients yet diagnosis is challenging, time consuming, and costly. This study evaluated the Self-Administered Gerocognitive Exam (SAGE) as a screening test for cognitive impairment in a cohort of SLE patients. Methods A total of 118 SLE patients completed the SAGE. Providers completed the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and the Systemic Lupus International Collaborative Clinics Damage Index (SLICC-DI). SAGE scores were grouped into normal (>16) and abnormal (≤16) categories. Univariate and multivariate analyses were performed. Results Of the 118 participants, 21(18%) scored ≤16 on the SAGE instrument. In univariate analysis, race, ethnicity, household income, and SLICC-DI scores were associated with the SAGE ( p SAGE score was independently associated with higher SLICC-DI score (odds ratio (OR) = 1.44, 95% confidence intervals 1.04-1.99, p = 0.03)), Hispanic ethnicity (OR = 43.4, 95% CI 3.1-601, p = 0.005), and lower household income (OR = 11.9 for ≤$15,000 vs >$50,000, 95% CI 2.45-57, p = 0.002). Conclusions In SLE patients, this study demonstrates an independent relationship between neurocognitive impairment (as measured by the SAGE) and higher lupus-related damage, as measured by the SLICC-DI, and lower household income. Abnormal SAGE scores were also associated with Hispanic ethnicity. A language barrier could explain this because the SAGE instrument was conducted in English only. The SAGE was feasible to measure in the clinic setting.

    A physiologically-based pharmacokinetic (PBPK) model of the vaginal space was developed with the aim of predicting concentrations in the vaginal and cervical space. These predictions can be used to optimize the probability of success of vaginally administered dapivirine (DPV) for HIV prevention. We focus on vaginal delivery using either a ring or film. A PBPK model describing the physiological structure of the vaginal tissue and fluid was defined mathematically and implemented in MATLAB. Literature reviews provided estimates for relevant physiological and physiochemical parameters. Drug concentration-time profiles were simulated in luminal fluids, vaginal tissue and plasma after administration of ring or film. Patient data were extracted from published clinical trials and used to test model predictions. The DPV ring simulations tested the two dosing regimens and predicted PK profiles and area under the curve of luminal fluids (29 079 and 33 067 mg h l -1 in groups A and B, respectively) and plasma (0.177 and 0.211 mg h l -1 ) closely matched those reported (within one standard deviation). While the DPV film study reported drug concentration at only one time point per patient, our simulated profiles pass through reported concentration range. HIV is a major public health issue and vaginal microbicides have the potential to provide a crucial, female-controlled option for protection. The PBPK model successfully simulated realistic representations of drug PK. It provides a reliable, inexpensive and accessible platform where potential effectiveness of new compounds and the robustness of treatment modalities for pre-exposure prophylaxis can be evaluated. © 2018 The Authors.

    To describe the effects of alpha2 -adrenergic receptor antagonists on the pharmacodynamics of sublingual (SL) detomidine in the horse. Randomized crossover design. Nine healthy adult horses with an average age of 7.6 ± 6.5 years. Four treatment groups were studied: 1) 0.04 mg kg(-1) detomidine SL; 2) 0.04 mg kg(-1) detomidine SL followed 1 hour later by 0.075 mg kg(-1) yohimbine intravenously (IV); 3) 0.04 mg kg(-1) detomidine SL followed 1 hour later by 4 mg kg(-1) tolazoline IV; and 4) 0.04 mg kg(-1) detomidine SL followed 1 hour later by 0.12 mg kg(-1) atipamezole IV. Each horse received all treatments with a minimum of 1 week between treatments. Blood samples were obtained and plasma analyzed for yohimbine, atipamezole and tolazoline concentrations by liquid chromatography-mass spectrometry. Behavioral effects, heart rate and rhythm, glucose, packed cell volume (PCV) and plasma proteins were monitored. Chin-to-ground distance increased following administration of the antagonists, however, this effect was transient, with a return to pre-reversal values as early as 1 hour. Detomidine induced bradycardia and increased incidence of atrioventricular blocks were either transiently or incompletely antagonized by all antagonists. PCV and glucose concentrations increased with tolazoline administration, and atipamezole subjectively increased urination frequency but not volume. At the doses administered in this study, the alpha2 -adrenergic antagonistic effects of tolazoline, yohimbine and atipamezole on cardiac and behavioral effects elicited by SL administration of detomidine are transient and incomplete. © 2013 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

    Despite the paucity of data available, orally administered angiotensin-converting enzyme (ACE) inhibitors are empirically used in horses with valvular regurgitation. Evaluate the echocardiographic and hormonal changes in response to oral benazepril in horses with left-sided valvular regurgitation. Prospective, randomised double-blind, placebo-controlled trial. Horses with mitral valve (MR) and/or aortic valve regurgitation (AR) received oral benazepril (n = 6) at a dosage of 1 mg/kg q 12 h or a placebo (n = 5) for 28 days. Echocardiography was performed before drug administration and after 28 days of treatment. Plasma renin activity, serum ACE activity, angiotensin II concentration, aldosterone concentration and biochemical variables were measured before drug administration and after 7 and 28 days of treatment. Relative to baseline, horses treated with benazepril had statistically significant reduction in left ventricular internal diameter in systole (mean difference between groups = -0.97 cm; 95% CI = -1.5 to -0.43 cm), aortic sinus diameter (-0.31 cm; -0.54 to -0.07 cm), and percentage of the aortic annulus diameter occupied by the base of the AR jet (-17.05%; -31.17 to -2.93%) compared with horses receiving a placebo. In addition, horses treated with benazepril had a significantly greater increase in cardiac output (11.95 L/min; 1.17-22.73 L/min) and fractional shortening (7.59%; 3.3-11.88%) compared with horses receiving a placebo. Despite profound serum ACE inhibition, renin activity and concentrations of angiotensin II and aldosterone were not significantly different between treatment groups or among time points. Very small sample size and short treatment period. Treatment with oral benazepril resulted in statistically significant echocardiographic changes that might indicate reduced cardiac afterload in horses with left-sided valvular regurgitation. Additional studies with a larger sample size will be necessary to determine if administration of benazepril is

    Fluralaner is a potent insecticide and acaricide with rapid and persistent efficacy. This study measured the efficacy of fluralaner flavored chews (Bravecto®, Merck Animal Health) administered to dogs against adult Ctenocephalides felis felis and egg production. Twelve purpose-bred dogs were randomly allocated to two groups of six dogs each. Dogs in treatment group 1 were administered a single fluralaner flavored chew to achieve a minimum dose of at least 25 mg/kg while treatment group 2 served as untreated controls. On Days -2, 28, 56, 84, 91, 98, 105, 112, and 120 post-treatment, each dog was infested with approximately 200 unfed cat fleas, C. felis felis (KS1 strain). Forty-eight hours after treatment and 48 h after each infestation, eggs were collected over a 3-h period, counted and viability determined. Dogs were combed to remove any remaining fleas. Treatment of dogs with oral fluralaner provided a 100% reduction in flea counts 48 h after treatment and within 48 h of every post-treatment infestation through Day122. Egg production from fluralaner treated dogs was reduced by 99.9% (two eggs from one dog) within 48 h after treatment and not a single egg (100% efficacy) was thereafter collected from treated dogs. Adult flea counts and egg production from the fluralaner-treated dogs were significantly lower than for non-treated controls at all post-treatment evaluations (P dog 48 h after treatment did not produce any adult fleas. As no additional eggs were collected from treated dogs, no viability assessment was performed. A single oral dose of fluralaner flavored chews provided 100% efficacy against repeated flea infestations on dogs for 4 months. Fluralaner reduced egg production of activity reproducing female fleas by 99.9% and then killed every single female flea before any eggs could be produced following each subsequent re-infestation for the entire 122-day evaluation period.

    Externalizing problem behaviour is one of the most common childhood disorders. Parent training is an effective treatment for these children and there is growing interest in the effects of parent-administered interventions with minimal therapist contact. This randomized controlled study examined the efficacy of a telephone-assisted parent-administered behavioural intervention (bibliotherapy) in families with preschool children with externalizing problem behaviour. Families were randomly assigned to a treatment group (n = 26) and an untreated waitlist control group (n = 22). The intervention comprised the reading of an 11 chapter self-help book and 11 weekly telephone consultations. Compared to the control group, the treatment group demonstrated significant decreases in parent-reported externalizing and internalizing child problem behaviour and dysfunctional parenting practices. Moreover, treated parents reported less parenting-related strains and decreases in parental depression, anxiety, and stress. The results suggest that telephone-assisted self-administered parent training is an effective alternative to more intensive forms of behavioural family intervention for preschool children with externalizing problem behaviour.

    Hospital information system data of cerebral infaction patients who received parenterally administered Shuxuetong was analyzed. This provided frequency data regarding patients' conditions and related information in order to provide a clinical reference guide. In this study, HIS data from 18 hospitals was analyzed. Patients receiving parenterally administered Shuxuetong for the treatment of cerebral infarction were included. Information on age, gender, costsand route of administration were collated. The average age of patients was 66 years old. Days of hospitalization ranged from 15 to 28 days. The majority of patients were classified as having phlegm and blood stasis syndrome, which is inaccordance with the indications for this drug. The most commonly used drugs used in combination with parenterally administered Shuxuetong were: aspirin, insulin and heparin. Patients with cerebral infarction crowd using parenterally administered Shuxuetong were a mostly elderly population, with an average age of 66. Although generally use was in accordance with indications, dosage, and route of administration, there were however some discrepancies. Therefore, doctors need to pay close attention to guidelines and closely observe patients when using parenterally administered Shuxuetong and to consider both the clinical benefits and risks.

    Outcome measures can be used in prosthetic practices to evaluate interventions, inform decision making, monitor progress, document outcomes, and justify services. Strategies to enhance prosthetists' ability to use outcome measures are needed to facilitate their adoption in routine practice. To assess prosthetists' use of outcome measures and evaluate the effects of training on their confidence in administering performance-based measures. Cross-sectional and single-group pretest-posttest survey. Seventy-nine certified prosthetists (mean of 16.0 years of clinical experience) were surveyed about their experiences with 20 standardized outcome measures. Prosthetists were formally trained by the investigators to administer the Timed Up and Go and Amputee Mobility Predictor. Prosthetists' confidence in administering the Timed Up and Go and Amputee Mobility Predictor was measured before and after training. The majority of prosthetists (62%) were classified as non-routine outcome measure users. Confidence administering the Timed Up and Go and Amputee Mobility Predictor prior to training was low-to-moderate across the study sample. Training significantly (p measures. Interactive training resulted in a statistically significant increase of prosthetists' confidence in administering the Timed Up and Go and Amputee Mobility Predictor and may facilitate use of outcome measures in clinical practice. Frequency of outcome measure use in the care of persons with limb loss has not been studied. Study results suggest that prosthetists may not regularly use standardized outcome measures and report limited confidence in administering them. Training enhances confidence and may encourage use of outcome measures in clinical practice. © The International Society for Prosthetics and Orthotics 2014.

    Atypical antipsychotics have been used to treat fear and anxiety disturbance that are highly common in schizophrenic patients. It is suggested that disruptions of N-methyl-d-aspartate (NMDA)-mediated transmission of glutamate may underlie the pathophysiology of schizophrenia. The present study was conducted to analyze the effectiveness of clozapine on the anxiety-related behavior and locomotor function of the adult brain, which had previously undergone NMDA receptor blockade during a developmental period. In order to block the NMDA receptor, male mice were administered 0.25 mg/kg of MK-801 on days 7 to 10 postnatal. In adulthood, they were administered intraperitoneally 0.5 mg/kg of clozapine and tested with open-field and elevated plus maze test, to assess their emotional behavior and locomotor activity. In the group receiving MK-801 in the early developmental period the elevated plus maze test revealed a reduction in the anxiety-related behavior (ptest indicated a decrease in locomotor activity (plocomotor activity and anxiety-related behavior, induced by administration of the MK-801 in neonatal period.

    Full Text Available The following text reviews the diagnosis that Jung makes about a Modernity that feeds a ‘shadow’ or a terrible self-destructive power, because it does not allow the development of the contents of the colective unconscious. In this context the present article approaches notions such as symbol, archetype, ‘self’, wisdom, Apocalypse, and also Jung’s critic to the churches and to the occidental rationalism. This notions and this critic are the conceptual frame from which Jung explains a Modernity that in its socialist, comunist and capitalist versions has given place to awful events such as the nazi’s concentration camps, the sovietic Gulag, or the atomic bomb. El presente texto tiene como objeto revisar el diagnóstico que Jung realiza sobre una modernidad que al no permitir el desarrollo de los contenidos del registro anímico del inconsciente colectivo, cultiva una “sombra” que es fuente de un terrible poder autodestructivo. En este marco, se abordan nociones como símbolo, arquetipo, “sí mismo”, sabiduría, apocalipsis, así como la crítica jungueana a las Iglesias y al racionalismo occidental. Estas nociones y dicha crítica constituyen el andamiaje conceptual a partir del cual Jung da cuenta de una modernidad que en sus versiones socialista, comunista y capitalista, ha dado lugar a hechos abominables como los alemanes campos de concentración, el Gulag soviético y la bomba atómica.

    A 60-year-old man with a history of hepatic cirrhosis and cardiomyopathy underwent transoesophageal echocardiogram. He received mild sedation and topical lidocaine. During the recovery period the patient developed ataxia and diplopia for about 30 mins, a result of lidocaine toxicity. The patient was administered a commonly used local anaesthetic, a combination of 2% viscous lidocaine, 4% lidocaine gargle and 5% lidocaine ointment topically to the oropharnyx. The total dose was at least 280 mg. Oral lidocaine undergoes extensive first pass metabolism and its clearance is quite dependent on rates of liver blood flow as well as other factors. The patient's central nervous system symptoms were mild and transient but remind us that to avoid adverse side effects, orally administered drugs with fairly high hepatic extraction ratio given to patients with chronic liver disease need to be given in reduced dosages. Even ‘Safe’ medications need to be carefully administered. PMID:23283606

    2015-12-01

    In surveys, individuals tend to misreport behaviors that are in contrast to prevalent social norms or regulations. Several design features of the survey procedure have been suggested to counteract this problem; particularly, computerized surveys are supposed to elicit more truthful responding. This assumption was tested in a meta-analysis of survey experiments reporting 460 effect sizes (total N =125,672). Self-reported prevalence rates of several sensitive behaviors for which motivated misreporting has been frequently observed were compared across self-administered paper-and-pencil versus computerized surveys. The results revealed that computerized surveys led to significantly more reporting of socially undesirable behaviors than comparable surveys administered on paper. This effect was strongest for highly sensitive behaviors and surveys administered individually to respondents. Moderator analyses did not identify interviewer effects or benefits of audio-enhanced computer surveys. The meta-analysis highlighted the advantages of computerized survey modes for the assessment of sensitive topics.

  13. Effect of tubing on loss of clonazepam administered by continuous subcutaneous infusion.

    Schneider, Jennifer J; Good, Phillip; Ravenscroft, Peter J

    2006-06-01

    Previous studies have reported loss of clonazepam from solutions administered intravenously from plastic infusion bags and administration sets. In palliative care, clonazepam is sometimes administered through syringe drivers using polyvinyl chloride (PVC) infusion tubing. No data currently exist to show whether use of PVC tubing affects the amount of clonazepam actually received by the patient. This study compared the use of two different types of PVC tubing with a non-PVC tubing. Solutions containing clonazepam or clonazepam and morphine were prepared with either normal saline or water for injection as diluent. Concentrations of morphine and clonazepam were determined using high-performance liquid chromatography. Significant loss of clonazepam (up to 50%) was observed in all solutions infused through PVC tubing. Solutions infused through non-PVC tubing retained greater than 90% of the initial concentration of clonazepam. It is recommended that when administering clonazepam using a syringe driver, non-PVC tubing be used.

Sedation was subjectively assessed and recorded on a visual analogue scale. Peak sedation and duration of sedation were investigated using a univariate general linear model with post-hoc Tukey tests (Pdetomidine from 10 to 20 µg/kg increased the degree of sedation when administered with the same dose of buprenorphine (7.5 µg/kg). When administered with 20 µg/kg detomidine, increasing the dose of buprenorphine from 7.5 to 10 µg/kg did not influence the degree of sedation achieved.

    Radiopharmaceuticals used in hospitals have remarkably increased in amount. Among radioactive matters discharged from pharmaceuticals administered into human bodies, a small amount of radio-pharmaceuticals remained in disporsable containers and syringes, excreta from patients administered such drugs and their washing, may cause the problems, radioisotopes with short half-life such as sup(99m)Tc tend to be administered increasingly while radioisotopes with long life have been decreasing. Long life radioactive wastes and short life wastes have to be strictly separated. And then long life radioisotopes wastes have to be condensed and stored, less than a tenth of the maximum allowable density after decay to discharge. Radioactive gas as 133 Xe should be diffused by ventilation. This is the time to make the numerical guide concerning the problem. (Kobatake, H.)

    The possibility of a radiological risk reduction in Nuclear Medicine patients is studied through the reduced absorbed doses in organs and tissues, and whole-body effective dose due to optimization of the administered radionuclide activities. Activity values, optimized for equipments and radiopharmaceuticals available in Cuba, are compared with the IAEA recommended values and with the routinary activities in medical practice. All doses were calculated using MIRDOSE 3.0 code for each activity and medical assay. The activity optimization permits to reduce in a 50% the doses administered to patients of the major part of studied medical assays. (Author)

  19. Improved metabolic control in tetrahydrobiopterin (BH4), responsive phenylketonuria with sapropterin administered in two divided doses vs. a single daily dose.

    2017-07-26

    Phenylketonuria (PKU) often requires a lifelong phenylalanine (Phe)-restricted diet. Introduction of 6R-tetrahydrobiopterin (BH4) has made a huge difference in the diets of patients with PKU. BH4 is the co-factor of the enzyme phenylalanine hydroxylase (PAH) and improves PAH activity and, thus, Phe tolerance in the diet. A limited number of published studies suggest a pharmacodynamic profile of BH4 more suitable to be administered in divided daily doses. After a 72-h BH4 loading test, sapropterin was initiated in 50 responsive patients. This case-control study was conducted by administering the same daily dose of sapropterin in group 1 (n=24) as a customary single dose or in two divided doses in group 2 (n=26) over 1 year. Mean daily consumption of Phe increased significantly after the first year of BH4 treatment in group 2 compared to group 1 (p<0.05). At the end of the first year of treatment with BH4, another dramatic difference observed between the two groups was the ability to transition to a Phe-free diet. Eight patients from group 2 and two from group 1 could quit dietary restriction. When given in two divided daily doses, BH4 was more efficacious than a single daily dose in increasing daily Phe consumption, Phe tolerance and the ability to transition to a Phe-unrestricted diet at the end of the first year of treatment.

    Streptococcus agalactiae (Group B streptococcus) is an important cause of disease in infants, pregnant women, the elderly and in immunosuppressed adults. An effective vaccine is likely to prevent the majority of infant disease (both early and late onset), as well as Group B streptococcus-related stillbirths and prematurity, to avoid the current real and theoretical limitations of intrapartum antibiotic prophylaxis, and to be cost effective. The optimal time to administer such a vaccine would be in the third trimester of pregnancy. The main limitations on the production of a Group B streptococcus vaccine are not technical or scientific, but regulatory and legal. A number of candidates including capsular conjugate vaccines using traditional carrier proteins such as tetanus toxoid and mutant diphtheria toxin CRM197, as well as Group B streptococcus-specific proteins such as C5a peptidase, protein vaccines using one or more Group B streptococcus surface proteins and mucosal vaccines, have the potential to be successful vaccines. The capsular conjugate vaccines using tetanus and CRM197 carrier proteins are the most advanced candidates, having already completed Phase II human studies including use in the target population of pregnant women (tetanus toxoid conjugate), however, no definitive protein conjugates have yet been trialed. However, unless the regulatory environment is changed specifically to allow the development of a Group B streptococcus vaccine, it is unlikely that one will ever reach the market.

    Several instruments developed to assess dietary intake of groups or populations have strengths and weaknesses that affect their specific application. No self-administered, closed-ended dietary survey was previously used in Argentina to assess current food and nutrient intake on a daily basis. To design and validate a self-administered, structured food record (NutriQuid, NQ) representative of the adult Argentine population's food consumption pattern to measure individual energy and nutrient intake. Records were loaded onto a database using software that checks a regional nutrition information system (SARA program), automatically quantifying energy and nutrient intake. NQ validation included two phases: (1) NQ construct validity comparing records kept simultaneously by healthy volunteers (45-75 years) and a nutritionist who provided meals (reference), and (2) verification of whether NQ reflected target population consumption (calories and nutrients), week consumption differences, respondent acceptability, and ease of data entry/analysis. Data analysis included descriptive statistics, repeated measures ANOVA, intraclass correlation coefficient, nonparametric regression, and cross-classification into quintiles. The first validation (study group vs. reference) showed an underestimation (10%) of carbohydrate, fat, and energy intake. Second validation: 109 volunteers (91% response) completed the NQ for seven consecutive days. Record completion took about 9min/day, and data entry 3-6min. Mean calorie intake was 2240±119kcal/day (42% carbohydrates, 17% protein, and 41% fat). Intake significantly increased in the weekend. NQ is a simple and efficient tool to assess dietary intake in large samples. Copyright © 2018 SEEN y SED. Publicado por Elsevier España, S.L.U. All rights reserved.

    The COOP/WONCA test was initially proposed as a self-report in which the answers were supported by drawings illustrating the state investigated. Subsequent studies have confirmed its usefulness as a mere verbal self-report face-to-face administered. No data have been found about its useful when administered by telephone interview. The aim of this study was to determine the psychometric properties of the COOP / WONCA test to measure Related Quality of Life (HRQoL) administered by telephone and compare them with those obtained in other forms of prior administration. Cross-sectional study on a random. City of Madrid. Random sample of 802 adult subjects, representative of the adult population in Madrid, obtained by stratification from the population census. Questionnaire COOP/WONCA with 9 ítems included in a broader battery, administered by telephone interview. The unrestricted factor analysis points to the unifactoriality of the scale, which measures a single latent construct (HRQOL), showing high internal consistency, not significantly different from those found by face-to-face administration, ruling out the existence of biases in the phone modality. The COOP/WONCA test appears as a reliable and valid measure of HRQOL and telephonic administration allows to assume no changes in the results, which can reduce costs in population studies, increasing efficiency without loss of quality in the information collected.

    Caecal acidosis is a central event in the metabolic cascade that occurs following grain overload. Buffering the caecal acidosis by enterally administered sodium bicarbonate (NaHCO3 ) may be beneficial to affected horses. To determine the effect and duration of enterally administered NaHCO3 on caecal pH in healthy horses. Experimental study using horses with caecal cannulas. Nine horses had been previously fitted with a caecal cannula. Six horses received 1.0 g/kg bwt NaHCO3 and 3 control horses were given 3 l of water via nasogastric tube. Clinical parameters, water consumption, venous blood gases, caecal pH, faecal pH and faecal water content were measured at 6 h intervals over a 36 h study period. Horses that received enterally administered NaHCO3 had significantly increased caecal pH that lasted the duration of the study.

    Mobile devices are increasingly used to administer self-report measures of mental health symptoms. There are significant differences, however, in the way that information is presented on mobile devices compared to the traditional paper forms that were used to administer such measures. Such differences may systematically alter responses. The present study evaluated if and how responses differed for a self-report measure, the PTSD Checklist (PCL), administered via mobile device relative to paper and pencil. Participants were 153 trauma-exposed individuals who completed counterbalanced administrations of the PCL on a mobile device and on paper. PCL total scores (d = 0.07) and item responses did not meaningfully or significantly differ across administrations. Power was sufficient to detect a difference in total score between administrations determined by prior work of 3.46 with a d = 0.23. The magnitude of differences between administration formats was unrelated to prior use of mobile devices or participant age. These findings suggest that responses to self-report measures administered via mobile device are equivalent to those obtained via paper and they can be used with experienced as well as naïve users of mobile devices.

    Cognitive environmental enrichment (C-EE) offers promise for offsetting neural decline that is observed in chronic moderate-severe traumatic brain injury (TBI). Brain games are a delivery modality for C-EE that can be self-administered over the Internet without therapist oversight. To date, only one study has examined the feasibility of self-administered brain games in TBI, and the study focused predominantly on mild TBI. Therefore, the primary purpose of the current study was to examine the feasibility of self-administered brain games in moderate-severe TBI. A secondary and related purpose was to examine the feasibility of remote monitoring of any C-EE-induced adverse symptoms with a self-administered evaluation tool. Ten patients with moderate-severe TBI were asked to complete 12 weeks (60 min/day, five days/week) of online brain games with bi-weekly self-evaluation, intended to measure any adverse consequences of cognitive training (e.g., fatigue, eye strain). There was modest weekly adherence (42.6% ± 4.4%, averaged across patients and weeks) and 70% patient retention; of the seven retained patients, six completed the self-evaluation questionnaire at least once/week for each week of the study. Even patients with moderate-severe TBI can complete a demanding, online C-EE intervention and a self-administered symptom evaluation tool with limited therapist oversight, though at daily rate closer to 30 than 60 min per day. Further self-administered C-EE research is underway in our lab, with more extensive environmental support. Implications for Rehabilitation Online brain games (which may serve as a rehabilitation paradigm that can help offset the neurodegeneration observed in chronic TBI) can be feasibly self-administered by moderate-to-severe TBI patients. Brain games are a promising therapy modality, as they can be accessed by all moderate-to-severe TBI patients irrespective of geographic location, clinic and/or therapist availability, or impairments that

    Chloroform, a halogenated hydrocarbon, causes central nervous system depression, cardiac arrhythmias, and hepatotoxicity. We describe a case of chloroform ingestion with a confirmatory serum level and resultant hepatotoxicity successfully treated with intravenously administered N-acetylcysteine (NAC). A 19-year-old man attempting suicide ingested approximately 75 mL of chloroform. He was unresponsive and intubated upon arrival. Intravenously administered NAC was started after initial stabilization was complete. His vital signs were normal. Admission laboratory values revealed normal serum electrolytes, AST, ALT, PT, BUN, creatinine, and bilirubin. Serum ethanol level was 15 mg/dL, and aspirin and acetaminophen were undetectable. The patient was extubated but developed liver function abnormalities with a peak AST of 224 IU/L, ALT of 583 IU/L, and bilirubin level reaching 16.3 mg/dL. NAC was continued through hospital day 6. Serum chloroform level obtained on admission was 91 μg/mL. The patient was discharged to psychiatry without known sequelae and normal liver function tests. The average serum chloroform level in fatal cases of inhalational chloroform poisoning was 64 μg/mL, significantly lower than our patient. The toxicity is believed to be similar in both inhalation and ingestion routes of exposure, with mortality predominantly resulting from anoxia secondary to central nervous system depression. Hepatocellular toxicity is thought to result from free radical-induced oxidative damage. Previous reports describe survival after treatment with orally administered NAC, we report the first use of intravenously administered NAC for chloroform ingestion. Acute oral ingestion of chloroform is extremely rare. Our case illustrates that with appropriate supportive care, patients can recover from chloroform ingestion, and intravenously administered NAC may be of benefit in such cases.

    The goal of this study is to quantify the number of medications administered to burn patients and identify potential drugs interfering with laboratory testing. The authors reviewed the medical records of 12 adult (age ≥ 18 years) burn patients with more than 20% TBSA burns from an existing glucose control database at our institution. Dose, interval, and route of medications administered from admission to discontinuation of intensive insulin therapy were recorded. Interfering drugs were identified based on established clinical chemistry literature. The retrospective cohort of adult burn patients exhibited a mean (SD) age of 37.9 (3.0) years. Mean TBSA burn was 51.3 (9.3)%. Disease severity determined by the average multiple organ dysfunction score was 5.4 (0.2). Mean and median medications administered per day were 42.1 (9.5) and 49 (with a daily range of 0-65), respectively. A total of 666 potential laboratory test interferences caused by medications were identified. There were 261 different effects (eg, increased glucose, decreased potassium). Multiple interferences, 71.0% (475/666), were caused by more than one medication. Investigation of the number of medications administered to a burn patient and delineation of potential laboratory test interferences has not been conducted in burn patients. Given the substantial number of medications administered to burn patients, physicians and laboratory personnel should work together to identify potential interferences and define appropriate countermeasures while enhancing the laboratorians understanding of this unique population. This synergistic partnership can lead to intelligent support tools and potentially autocorrecting instruments.

    Current measures of health literacy have been criticized on a number of grounds, including use of a limited range of content, development on small and atypical patient groups, and poor psychometric characteristics. In this paper, we report the development and preliminary validation of a new computer-administered and -scored health literacy measure addressing these limitations. Items in the measure reflect a wide range of content related to health promotion and maintenance as well as care for diseases. The development process has focused on creating a measure that will be useful in both Spanish and English, while not requiring substantial time for clinician training and individual administration and scoring. The items incorporate several formats, including questions based on brief videos, which allow for the assessment of listening comprehension and the skills related to obtaining information on the Internet. In this paper, we report the interim analyses detailing the initial development and pilot testing of the items (phase 1 of the project) in groups of Spanish and English speakers. We then describe phase 2, which included a second round of testing of the items, in new groups of Spanish and English speakers, and evaluation of the new measure's reliability and validity in relation to other measures. Data are presented that show that four scales (general health literacy, numeracy, conceptual knowledge, and listening comprehension), developed through a process of item and factor analyses, have significant relations to existing measures of health literacy.

    No immunogenicity data has been reported after a single dose of the quadrivalent HPV vaccine (qHPV-Gardasil®) and no data are available on co-administration of this vaccine with the HAV/HBV vaccine (Twinrix-Junior®). Two pre-licensure studies reported similar anti-HPV but lower anti-HBs titers when co-administering HPV and HBV vaccines. To assess the immunogenicity of the qHPV and HAV/HBV vaccine when co-administered (Group-Co-adm) or given one month apart (Group-Sep) and to measure the persistence of HPV antibodies three years post-second dose of qHPV vaccine in both study groups. 416 9-10 year-old girls were enrolled. Vaccination schedule was 0-6 months. Anti-HAV and anti-HBs were measured in all subjects 6 months post-first dose and 1 month post-second dose. Anti-HPV were measured 6 months post-first dose in Group-Co-adm and in all subjects 1 and 36 months post-second dose. Six months post-first dose: 100% of subjects had detectable anti-HAV and 56% and 73% had detectable anti-HBs in Group-Co-Adm and Group-Sep, respectively. In Group-Co-adm 94, 100, 99 and 96% had detectable antibodies to HPV 6, 11, 16 and 18, respectively. One month post-second dose of qHPV and HAV/HBV vaccine, in both study groups 99.5-100% of subjects had an anti-HAV titer ≥ 20IU/L, 97.5-97.6% an anti-HBs level ≥ 10IU/L, and 100% had an anti-HPV titer ≥ 3LU. Thirty-six months post-second dose of qHPV all but four subjects (99%) had antibodies to HPV18 and 100% had antibodies to HPV6, 11 and 16. The great majority (97-100%) had an anti-HPV titer ≥ 3 LU. Post-second dose administration of qHPV and HAV/HBV, no meaningful difference was observed in the immune response in the two study groups to any component of vaccines. The results indicate that qHPV and HAV/HBV can be given during the same vaccination session. Two doses of of qHPV and HAV/HBV vaccines induce a strong immune response. Three years post-second dose of qHPV, the great majority of subjects had antibodies to HPV types

    2009-12-01

    The National Cancer Institute (NCI) is developing an automated, self-administered 24-hour dietary recall (ASA24) application to collect and code dietary intake data. The goal of the ASA24 development is to create a web-based dietary interview based on the US Department of Agriculture (USDA) Automated Multiple Pass Method (AMPM) instrument currently used in the National Health and Nutrition Examination Survey (NHANES). The ASA24 food list, detail probes, and portion probes were drawn from the AMPM instrument; portion-size pictures from Baylor College of Medicine's Food Intake Recording Software System (FIRSSt) were added; and the food code/portion code assignments were linked to the USDA Food and Nutrient Database for Dietary Studies (FNDDS). The requirements that the interview be self-administered and fully auto-coded presented several challenges as the AMPM probes and responses were linked with the FNDDS food codes and portion pictures. This linking was accomplished through a "food pathway," or the sequence of steps that leads from a respondent's initial food selection, through the AMPM probes and portion pictures, to the point at which a food code and gram weight portion size are assigned. The ASA24 interview database that accomplishes this contains more than 1,100 food probes and more than 2 million food pathways and will include about 10,000 pictures of individual foods depicting up to 8 portion sizes per food. The ASA24 will make the administration of multiple days of recalls in large-scale studies economical and feasible.

    Background Expanding latent tuberculosis treatment is important to decrease active disease globally. Once-weekly isoniazid and rifapentine for 12 doses is effective but limited by requiring direct observation. Objective To compare treatment completion and safety of once-weekly isoniazid and rifapentine by self-administration versus direct observation. Design An open-label, phase 4 randomized clinical trial designed as a noninferiority study with a 15% margin. Seventy-five percent or more of study patients were enrolled from the United States for a prespecified subgroup analysis. (ClinicalTrials.gov: NCT01582711) Setting Outpatient tuberculosis clinics in the United States, Spain, Hong Kong, and South Africa. Participants 1002 adults (aged ≥18 years) recommended for treatment of latent tuberculosis infection. Intervention Participants received once-weekly isoniazid and rifapentine by direct observation, self-administration with monthly monitoring, or self-administration with weekly text message reminders and monthly monitoring. Measurements The primary outcome was treatment completion, defined as 11 or more doses within 16 weeks and measured using clinical documentation and pill counts for direct observation, and self-reports, pill counts, and medication event–monitoring devices for self-administration. The main secondary outcome was adverse events. Results Median age was 36 years, 48% of participants were women, and 77% were enrolled at the U.S. sites. Treatment completion was 87.2% (95% CI, 83.1% to 90.5%) in the direct-observation group, 74.0% (CI, 68.9% to 78.6%) in the self-administration group, and 76.4% (CI, 71.3% to 80.8%) in the self-administration–with–reminders group. In the United States, treatment completion was 85.4% (CI, 80.4% to 89.4%), 77.9% (CI, 72.7% to 82.6%), and 76.7% (CI, 70.9% to 81.7%), respectively. Self-administered therapy without reminders was noninferior to direct observation in the United States; no other comparisons met

    Full Text Available Abstract Background Medical and public health importance of pneumococcal infections justifies the implementation of measures capable of reducing their incidence and severity, and explains why the recently marketed heptavalent pneumococcal conjugate vaccine (PCV-7 has been widely studied by pediatricians. This study was designed to evaluate the impact of PCV-7 administered at 3, 5 and 11 months of age on respiratory tract infections in very young children. Methods A total of 1,571 healthy infants (910 males aged 75–105 days (median 82 days were enrolled in this prospective cohort trial to receive a hexavalent vaccine (DTaP/IPV/HBV/Hib and PCV-7 (n = 819 or the hexavalent vaccine alone (n = 752 at 3, 5 and 11 months of age. Morbidity was recorded for the 24 months following the second dose by monthly telephone interviews conducted by investigators blinded to the study treatment assignment using standardised questionnaires. During these interviews, the caregivers and the children's pediatricians were questioned about illnesses and the use of antibiotics since the previous telephone call. All of the data were analysed using SAS Windows v.12. Results Among the 1,555 subjects (98.9% who completed the study, analysis of the data by the periods of follow-up demonstrated that radiologically confirmed community-acquired pneumonia (CAP was significantly less frequent in the PCV-7 group during the follow-up as a whole and during the last period of follow-up. Moreover, there were statistically significant between-group differences in the incidence of acute otitis media (AOM in each half-year period of follow-up except the first, with significantly lower number of episodes in children receiving PCV-7 than in controls. Furthermore, the antibiotic prescription data showed that the probability of receiving an antibiotic course was significantly lower in the PCV-7 group than in the control group. Conclusion Our findings show the effectiveness of the simplified

    To determine effects of i.v. administered yohimbine on perineal analgesia, cardiovascular and respiratory activity, and head and pelvic limb position in healthy mares following epidural administration of detomidine hydrochloride solution. 8 healthy mares. Each mare received detomidine hydrochloride (0.06 mg/kg of body weight), administered in the caudal epidural space, followed 61 minutes later by yohimbine (0.05 mg/kg; test) or sterile saline (0.9% NaCl) solution (control), administered i.v., in a randomized, crossover study design with > or = 2 weeks between treatments. Analgesia was determined by lack of sensory perception to electrical stimulation of perineal dermatomes and needle-prick stimulation of coccygeal to 15th thoracic dermatomes. Arterial pH, PaCO2, PaO2, heart and respiratory rates, rectal temperature, arterial blood pressure, and cardiac output were determined, and mares were observed for sweating and urination. Mean scores obtained for test and control groups were compared. Intravenously administered yohimbine significantly reduced mean scores of detomidine-induced perineal analgesia, head ptosis, changes in pelvic limb position, and sweating and diuresis; antagonized detomidine-induced decreases in heart rate and cardiac output; but did not affect detomidine-induced decrease in respiratory rate. Most effects of epidurally administered detomidine, except bradypnea, were antagonized by yohimbine, suggesting that detomidine may influence respiratory rate by mechanisms other than stimulation of alpha2-adrenoceptors, or that yohimbine induces respiratory depressant effects. Yohimbine may be an effective alpha2-adrenoceptor antagonist for all but respiratory depression following epidural administration of detomidine to mares.

  18. Hematological toxicity in radioimmunotherapy is predicted both by the computed absorbed whole body dose (cGy) and by the administered dose (mCi)

    1997-01-01

    Purpose/Objective: Radioimmunotherapy (RIT) has yielded encouraging response rates in patients with recurrent non-Hodgkin's lymphoma, but myelotoxicity remains the dose limiting factor. Dose optimization is theoretically possible, since a pretreatment biodistribution study with tracer doses allows for a fairly accurate estimate of the whole body (and by implication the bone marrow) dose in patients. It has been shown that the radiation dose as a function of the administered dose varies widely from patient to patient. The pretreatment study could therefore be used to determine the maximum tolerable dose for each individual patient. The purpose of this study was to examine whether the administered dose or the estimated whole body absorbed radiation dose were indeed predictors of bone marrow toxicity. Materials and Methods: We studied two cohorts of patients to determine if the computed integral whole body or marrow dose is predictive of myelotoxicity. The first cohort consisted of 13 patients treated with Yttrium-90 labeled anti-CD20 (2B8) monoclonal antibody. Those patients were treated in a dose escalation protocol, based on the administered dose, without correction for weight or body surface. The computed whole body dose varied from 41 to 129 cGy. The second cohort (6 patients) were treated with Iodine-131 labeled anti-CD20 (B1) antibody. In this group the administered dose was tailored to deliver an estimated 75 cGy whole body dose. The administered dose varied from 54 to 84 mCi of Iodine-131. For each patient, white blood cell count with differential, hemoglobin, hematocrit, and platelet levels were measured before and at regular intervals after RIT was administered. Using linear regression analysis, a relationship between administered dose, absorbed dose and myelotoxicity was determined for each patient cohort. Results: Marrow toxicity was measured by the absolute decrease in white blood cell (DWBC), platelet (DPLAT), and neutrophil (DN) values. In the Yttrium

    Full Text Available Abstract Background Herpes simplex virus type-1 (HSV-1 enters into cells via membrane fusion of the viral envelope with plasma or endosomal membranes mediated by viral glycoproteins. HSV-1 virions attach to cell surfaces by binding of viral glycoproteins gC, gD and gB to specific cellular receptors. Here we show that the human ocular and highly neurovirulent HSV-1 strain McKrae enters substantially more efficiently into cells via the gB-specific human paired immunoglobulin-like type-2 receptor-α (hPILR-α. Comparison of the predicted amino acid sequences between HSV-1(F and McKrae strains indicates that amino acid changes within gB, gC, gH and gL may cause increased entry via the hPILR- α receptor. Results HSV-1 (McKrae entered substantially more efficiently than viral strain F in Chinese hamster ovary (CHO cells expressing hPIRL-α but not within CHO-human nectin-1, -(CHO-hNectin-1, CHO-human HVEM (CHO-hHVEM or Vero cells. The McKrae genes encoding viral glycoproteins gB, gC, gD, gH, gL, gK and the membrane protein UL20 were sequenced and their predicted amino acid (aa sequences were compared with virulent strains F, H129, and the attenuated laboratory strain KOS. Most aa differences between McKrae and F were located at their gB amino termini known to bind with the PILRα receptor. These aa changes included a C10R change, also seen in the neurovirulent strain ANG, as well as redistribution and increase of proline residues. Comparison of gC aa sequences revealed multiple aa changes including an L132P change within the 129-247 aa region known to bind to heparan sulfate (HS receptors. Two aa changes were located within the H1 domain of gH that binds gL. Multiple aa changes were located within the McKrae gL sequence, which were preserved in the H129 isolate, but differed for the F strain. Viral glycoproteins gD and gK and the membrane protein UL20 were conserved between McKrae and F strains. Conclusions The results indicate that the observed

    Sexuality usually decreases during pregnancy. To evaluate sexual behavior during pregnancy, comparing two groups. One had sexual education and the other had none. After randomizing two groups of pregnant women, they completed self-administered questionnaires regarding attitudes and sexual behavior before and during pregnancy. Sexual education was provided in one group and a second self-administered questionnaire was completed 12 weeks later. Responses were summarized using descriptive statistics. Comparison of change of sexual behavior between two groups was analyzed using chi-square and student t-tests. The change in frequency of coitus during pregnancy was compared between the sexual education group and the noneducation group. There was no statistically difference in changes of sexual behavior between the two groups. There was a reduction in frequency of coitus (90.6% vs. 94.9%, P>0.05) between the nonsexual education group and the sexual education group and no statistically significant change in mean reduction of sexual desire (8.9 vs. 4.4, P>0.05), sexual arousal (14.3 vs. 13.1, P>0.05), satisfaction from coitus (15.4 vs. 7.2, P>0.05), and orgasm from coitus (12.3 vs. 12.3, P>0.05). The change of sexual behavior during pregnancy in the sexual education group was not different from that in the nonsexual education group. © 2010 International Society for Sexual Medicine.

    Objectives A xenogeneic human tyrosinase DNA vaccine was developed for treatment of dogs with oral malignant melanoma (Oncept; Merial). No studies have evaluated the safety or efficacy of this vaccine in cats. The purpose of this study was to evaluate the safety of the canine melanoma vaccine in cats diagnosed with melanoma. Methods Medical records were reviewed from cats diagnosed with malignant melanoma and treated with the canine melanoma DNA vaccine (Oncept). Data regarding signalment, melanoma location, treatments received, vaccine adverse effects and cause of death were collected. Results A total of 114 melanoma vaccines were administered to 24 cats. Seven cats (11.4%) had clinical adverse effects from a total of 13 vaccines classified as grade 1 or 2 based on the Veterinary Cooperative Oncology Group's common terminology criteria for adverse events v1.1. These included pain on vaccine administration, brief muscle fasciculation, transient inappetence, depression, nausea and mild increase in pigmentation at the injection site. Nineteen cats were deceased at study close. The most common cause of death was melanoma (14 cats). Hematological and biochemical changes were observed in six cats, five of which had concurrent disease or treatments that likely caused or greatly contributed to the laboratory abnormalities found. Therefore, these adverse events were considered unlikely to be caused by the melanoma vaccine. One cat had transient grade 1 hypoalbuminemia, which was possibly caused by the vaccination but not thoroughly evaluated. Conclusions and relevance The canine melanoma DNA vaccine can be safely administered to cats, with minimal risk of adverse effects.

    To assess the psychiatric side effects of ketamine when administered in subanesthetic doses to hospitalized patients. It is hypothesized that such effects occur frequently. In this retrospective study, the medical records of 50 patients hospitalized on medical and surgical units at our facility who had continuous intravenous infusions of ketamine for pain or mild sedation were reviewed. Patient progress in the days following the start of ketamine infusion was reviewed and response to ketamine was noted. Twenty-two percent of the patients were noted to have some type of psychiatric reaction to ketamine, including agitation, confusion, and hallucinations. These reactions were relatively short lived, namely, occurring during or shortly after the infusions. No association was found between patient response to ketamine and gender, age, or infusion rate. Awareness of the psychiatric side effects of ketamine is an important consideration for clinicians administering this medication either for pain control or for depressive illness.

    A survey was conducted among the Brazilian clinical PET, with the purpose of investigating the activities administered to pediatric oncology patients and assess whether significant differences between the protocols adopted. In addition, this survey can cooperate to the suggestion diagnostic reference levels (DRLs) in nuclear medicine. Although the methodology for delivering doses by most clinics be based on patient's weight, the results showed variations of up to 191, 6% between the activities administered in clinics, even for similar devices. The average value of the distribution of activities reported was 4.46 ± 1,6 MBq /kg. These data demonstrate the need for harmonization and optimization of 18 F-FDG/PET procedures, as well as training for professionals involved in the clinical routine

    The purpose of this study is to synthesize 123 I-labeled hesperetin and to investigate its in vivo behavior. The optimized labeling condition provided two isomers of 123 I-labeled hesperetin with high radiochemical yields and radiochemical purities. Both 123 I-labeled products were orally administered to normal ICR mice, and the initial result showed that most of 123 I activity was detected in the stomach and the intestines. A part of 123 I-labeled hesperetin was absorbed from the small intestine to bloodstream and then it was distributed in normal organs. The results in the present study provided an efficient radiolabeling method of flavonoid and quantitative organ distribution of orally administered hesperetin. (author)

    This study examined the feasibility of repeated self-administration of a newly developed battery of mental acuity tests which may have application in screening for fitness-for-duty or for persons who may be exposed to environmental stress, toxic agents, or disease. 16 subjects self-administered 18 microcomputer-based tests (13 new, 5 "core"), without proctors, over 10 sessions. The hardware performed well throughout the study and the tests appeared to be easily self-administered. Stabilities and reliabilities of the tests from the "core" battery were comparable to those obtained previously under more controlled experimental conditions. Eight of the new tests exceeded minimum criteria for metric and practical requirements and can be recommended as additions to the menu. Although the average retest reliability was high, cross-correlations between tests were low, implying factorial diversity. The menu can be used to form batteries with flexible total testing time which are likely to tap different mental processes and functions.

    Radiation burden estimates for upper gastrointestinal function studies employing the following orally administered radiopharmaceuticals are reported. Technetium 99m sulfur colloid (Tc-99m-SC) in water, Indium-111-DTPA in water, Tc-99m-DTPA in water, Indium-113m DTPA in water, Tc-99m Ovalbumin, Tc-99m sulfur colloid in a cooked egg, Tc-99m sulfur colloid in vivo labeled chicken liver, and Indium-111 colloid in vivo labeled chicken liver. Orally administered radiopharmaceuticals for upper gastrointestinal studies afford clinician and investigator valuable clinical and physiologic information not previously obtainable using other techniques. The radiation burden to the patient from single or sequential studies is acceptable in comparison to fluoroscopy which results in approximately 5000 millirem per minute of exposure. The variety of preparations listed above should make these types of studies available in any routinely equipped nuclear medicine radiopharmacy laboratory

  7. Repetitive immunization enhances the susceptibility of mice to peripherally administered prions.

    Directory of Open Access Journals (Sweden)

    Juliane Bremer

    Full Text Available The susceptibility of humans and animals to prion infections is determined by the virulence of the infectious agent, by genetic modifiers, and by hitherto unknown host and environmental risk factors. While little is known about the latter two, the activation state of the immune system was surmised to influence prion susceptibility. Here we administered prions to mice that were repeatedly immunized by two initial injections of CpG oligodeoxynucleotides followed by repeated injections of bovine serum albumin/alum. Immunization greatly reduced the required dosage of peripherally administered prion inoculum necessary to induce scrapie in 50% of mice. No difference in susceptibility was observed following intracerebral prion challenge. Due to its profound impact onto scrapie susceptibility, the host immune status may determine disease penetrance after low-dose prion exposure, including those that may give rise to iatrogenic and variant Creutzfeldt-Jakob disease.

    Co-administration of an investigational quadrivalent meningococcal serogroups A, C, W and Y tetanus toxoid conjugate vaccine (MenACWY-TT) with the fourth dose of diphtheria-tetanus-acellular pertussis vaccine (DTaP) at age 15-18 months was investigated in 3-dose Haemophilus influenzae type b-meningococcal serogroups C/Y conjugate vaccine (HibMenCY-TT)-primed toddlers. Infants were randomized (5:1) and primed at 2, 4 and 6 months of age with HibMenCY-TT and DTaP-hepatitis B-inactivated poliovirus (DTaP-HBV-IPV) vaccine, or Hib-TT and DTaP-HBV-IPV (Control). HibMenCY-TT+ DTaP-HBV-IPV vaccinees were re-randomized (2:2:1) to receive MenACWY-TT at 12-15 months and DTaP at 15-18 months (MenACWY-TT group); MenACWY-TT co-administered with DTaP at 15-18 months (Coad group); or HibMenCY-TT at 12-15 months and DTaP at 15-18 months (HibMenCY-TT group). Controls received DTaP at 15-18 months. Only children in the HibMenCY-TT group received a fourth dose of Hib conjugate vaccine due to Hib conjugate vaccine shortage at the time of the study. DTaP immunogenicity and reactogenicity were assessed one month post-vaccination. Pre-defined statistical non-inferiority criteria between Coad and Control groups were met for diphtheria, tetanus and filamentous haemagglutinin but not pertussis toxoid and pertactin. Following vaccination ≥99% of children had anti-diphtheria/anti-tetanus concentrations ≥1.0 IU/ml. Pertussis GMCs were lower in all investigational groups versus Control. In post hoc analyses, pertussis antibody concentrations were above those in infants following 3-dose DTaP primary vaccination in whom efficacy against pertussis was demonstrated (Schmitt, von König, et al., 1996; Schmitt, Schuind, et al., 1996). The reactogenicity profile of the Coad group was similar to DTaP administered alone. Routine booster DTaP was immunogenic with an acceptable safety profile when co-administered with MenACWY-TT vaccine in HibMenCY-TT-primed toddlers. These data support the

    Introduction Select units in the military have improved combat medic training by integrating their functions into routine clinical care activities with measurable improvements in battlefield care. This level of integration is currently limited to special operations units. It is unknown if regular Army units and combat medics can emulate these successes. The goal of this project was to determine whether US Army combat medics can be integrated into routine emergency department (ED) clinical care, specifically medication administration. Project Design This was a quality assurance project that monitored training of combat medics to administer parenteral medications and to ensure patient safety. Combat medics were provided training that included direct supervision during medication administration. Once proficiency was demonstrated, combat medics would prepare the medications under direct supervision, followed by indirect supervision during administration. As part of the quality assurance and safety processes, combat medics were required to document all medication administrations, supervising provider, and unexpected adverse events. Additional quality assurance follow-up occurred via complete chart review by the project lead. Data During the project period, the combat medics administered the following medications: ketamine (n=13), morphine (n=8), ketorolac (n=7), fentanyl (n=5), ondansetron (n=4), and other (n=6). No adverse events or patient safety events were reported by the combat medics or discovered during the quality assurance process. In this limited case series, combat medics safely administered parenteral medications under indirect provider supervision. Future research is needed to further develop this training model for both the military and civilian setting. Schauer SG , Cunningham C W, Fisher AD , DeLorenzo RA .

    Some polyaminocarboxylic acids were examined for their ability to mobilize chromium from certain vital organs, their subcellular fractions, and blood cells of potassium chromate administered rats. Hexamethylene 1,6-diamino tetraacetic acid (TDTA), triethylene tetramine hexaacetic acid (TTHA), and ethylene diamine di (O-hydroxylphenyl acetic acid) (EDDHA) may be useful in preventing or reducing chromate toxicity. No definite relationship could be observed between the structure of the chelating agents and their chromium-removing capacity.

    Virus-like particles (VLPs) are being evaluated as a candidate rotavirus vaccine. The immunogenicity and protective efficacy of different formulations of VLPs administered parenterally to rabbits were tested. Two doses of VLPs (2/6-, G3 2/6/7-, or P[2], G3 2/4/6/7-VLPs) or SA11 simian rotavirus in Freund’s adjuvants, QS-21 (saponin adjuvant), or aluminum phosphate (AlP) were administered. Serological and mucosal immune responses were evaluated in all vaccinated and control rabbits before and after oral challenge with 103 50% infective doses of live P[14], G3 ALA lapine rotavirus. All VLP- and SA11-vaccinated rabbits developed high levels of rotavirus-specific serum and intestinal immunoglobulin G (IgG) antibodies but not intestinal IgA antibodies. SA11 and 2/4/6/7-VLPs afforded similar but much higher mean levels of protection than 2/6/7- or 2/6-VLPs in QS-21. The presence of neutralizing antibodies to VP4 correlated (P < 0.001, r = 0.55; Pearson’s correlation coefficient) with enhanced protection rates, suggesting that these antibodies are important for protection. Although the inclusion of VP4 resulted in higher mean protection levels, high levels of protection (87 to 100%) from infection were observed in individual rabbits immunized with 2/6/7- or 2/6-VLPs in Freund’s adjuvants. Therefore, neither VP7 nor VP4 was absolutely required to achieve protection from infection in the rabbit model when Freund’s adjuvant was used. Our results show that VLPs are immunogenic when administered parenterally to rabbits and that Freund’s adjuvant is a better adjuvant than QS-21. The use of the rabbit model may help further our understanding of the critical rotavirus proteins needed to induce active protection. VLPs are a promising candidate for a parenterally administered subunit rotavirus vaccine. PMID:9765471

    To systematically review the effect of self-administered foot reflexology in patients with chronic health conditions. Electronic databases were searched for literature published from 1948 to January 2014. The databases included MEDLINE, EMBASE, the Cochrane Library, CINAHL, CNKI, J-STAGE, Koreamed, Kmbase, KISS, NDSL, KISTI, and OASIS. Key search terms were "exp/relaxation therapy," "foot," "reflexology," "zone therapy," and "self." All study designs were included. Two raters independently extracted data and assessed study quality by using the Cochrane risk of bias tool (for randomized controlled trials) and the risk of bias assessment tool for nonrandomized studies (for nonrandomized and before-and-after studies). A qualitative and descriptive analysis was performed because of the clinical diversity associated with chronic health conditions. Of the 224 records assessed, 4 trials met the inclusion criteria: 3 nonrandomized controlled trials and 1 before-and-after study without comparison. Self-administered foot reflexology might have a positive effect in type 2 diabetes, but the low quality of the included study and the lack of adequately reported clinical outcomes obscure the results. Two studies of hypertensive patients and 1 study of patients with urinary incontinence showed that self-performed foot reflexology may exert a beneficial effect on lowering blood pressure and urinary incontinence; however, given the small sample size and the lack of any description of medications and other cointerventions, there was insufficient evidence to conclusively determine whether foot reflexology had any effect. The included studies on self-administered foot reflexology in patients with type 2 diabetes, hypertension, or urinary incontinence provided insufficient evidence to determine a treatment effect. Therefore, a well-designed, large-scale, and randomized controlled trial is needed to confirm the effect of self-administered foot reflexology for chronic conditions.

    To assess the relative bioavailability of a new subcutaneous (SC) diclofenac hydroxypropyl b-cyclodextrin (HPbCD) formulation administered to three body sites: quadriceps, gluteus, and abdomen. This was a pilot, single-dose, randomized, three-way crossover relative bioavailability study. A total of 12 healthy subjects received a single SC injection of diclofenac HPbCD 50 mg/1 mL in the quadriceps, gluteus, or abdomen. The AUC was comparable after SC diclofenac HPbCD in the quadriceps, gluteus, and abdomen. The Cmax was comparable after SC administration in the quadriceps or abdomen, and ~ 17% higher in the gluteus. The absorption was rapid (30 minutes) after administration of the treatment at any site. The treatment was well tolerated. The relative bioavailability of SC diclofenac HPbCD was comparable when administered to the quadriceps, gluteus, and abdomen. The new diclofenac formulation can therefore be administered subcutaneously to any of these sites without clinically significant differences. A further adequately powered study would be necessary to reveal any differences among injection sites in terms of peak plasma concentration.

    The pharmacodynamics (PD) of oxytetracycline was investigated against a strain of Mannheimia haemolytica. In vitro measurements, comprising minimum inhibitory concentration (MIC), minimum bactericidal concentration and time-kill curves, were conducted in five matrices; Mueller Hinton Broth (MHB), cation-adjusted MHB (CAMHB) and calf serum, exudate and transudate. MICs were much higher in the biological fluids than in MHB and CAMHB. Ratios of MIC were, serum: CAMHB 19 : 1; exudate:CAMHB 16.1; transudate:CAMHB 14 : 1. Ex vivo data, generated in the tissue cage model of inflammation, demonstrated that oxytetracycline, administered to calves intramuscularly at a dose rate of 20 mg/kg, did not inhibit the growth of M haemolytica in serum, exudate and transudate, even at peak concentration. However, using in vitro susceptibility in CAMHB and in vivo-determined pharmacokinetic (PK) variables, average and minimum oxytetracycline concentrations relative to MIC (C(av)/MIC and C(min)/MIC) predicted achievement of efficacy for approximately 48 hours after dosing. Similar C(av)/MIC and C(min)/MIC data were obtained when oxytetracycline was administered in the presence of carprofen. PK-PD integration of data for oxytetracycline, based on MICs determined in the three biological fluids, suggests that it possesses, at most, limited direct killing activity against M haemolytica. These data raise questions concerning the mechanism(s) of action of oxytetracycline, when administered at clinically recommended dose rates.

    The aim of this study was to establish a method for determining administered activities for {sup 68}Ga-labelled peptides. Dose calculations were based on the weight-independent effective dose model proposed by the EANM paediatric dosage card for use in paediatric nuclear medicine. Previously published time-integrated activity coefficients for {sup 68}Ga-DOTATATE, {sup 68}Ga-DOTATOC and {sup 68}Ga-pentixafor were used to calculate age-independent effective doses. Consequently, the corresponding weight-dependent effective dose coefficients were rescaled according to the formalism of the EANM dosage card to determine the radiopharmaceutical class of {sup 68}Ga-labelled peptides (''multiples'') and to calculate the baseline activities based on an upper limit for administered activity (185 MBq) in an adult. All calculated normalization factors suggest that the {sup 68}Ga-labelled peptides are class ''B'' radiopharmaceuticals. The baseline activity for all compounds is 12.8 MBq. In analogy to {sup 18}F-fluoride, we recommend a minimum activity of 14 MBq. For paediatric nuclear medicine applications involving {sup 68}Ga-labelled peptides, we suggest determining administered activities based on the formalism proposed in this work. The corresponding effective doses from these procedures will remain age-independent. (orig.)

    Hypnotherapy is an effective treatment in irritable bowel syndrome (IBS). It is often delivered by a psychotherapist and is costly and time consuming. Nurse-administered hypnotherapy could increase availability and reduce costs. In this study the authors evaluate the effectiveness of nurse-administered, gut-directed hypnotherapy and identify factors predicting treatment outcome. Eighty-five patients were included in the study. Participants received hypnotherapy by a nurse once/week for 12 weeks. Patients reported marked improvement in gastrointestinal (GI) and extra-colonic symptoms after treatment, as well as a reduction in GI-specific anxiety, general anxiety, and depression. Fifty-eight percent were responders after the 12 weeks treatment period, and of these 82% had a favorable clinical response already at week 6. Women were more likely than men to respond favorably to the treatment. Nurse-administered hypnotherapy is an effective treatment for IBS. Being female and reporting a favorable response to treatment by week 6 predicted a positive treatment response at the end of the 12 weeks treatment period.

    Female rats exhibit greater intake and motivation to self-administer cocaine. In females but not males, isolation by itself is a stressor, which could lead to increased drug intake. Therefore, we hypothesized that social housing would buffer against stress and reduce the motivation to self-administer cocaine primarily in females. Male and female Sprague-Dawley rats were housed individually or in same-sex pairs. The individually housed rats and one of each pair were allowed to self-administer (SA) a low dose of cocaine (0.2 mg/kg/inf) on a fixed ratio (FR1) schedule for one week. Motivation for cocaine SA was measured for an additional 2 weeks on a progressive ratio schedule. Isolated females had greater cocaine-intake on the FR1 schedule and greater motivation to take cocaine than males. Pair-housing in females, but not males, attenuated the motivation to take cocaine. Isolated females, but not males, showed escalation of their motivation to take cocaine, which was attenuated by pair housing of females. Concluding, the motivation to take cocaine escalates in females but not males, and pair-housing of females attenuates this escalation. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available The objective of the study was to examine the relationships between several constructs that were hypothesised to be components underlying psychological wellness and to establish whether there were differences between managerial and non-managerial groups or between Black and White groups in respect of the wellness variables. The Personal Orientation Inventory (POI, Locus of Control Inventory (LOC, Sense of Coherence Scale (SOC, and the Bar-On EQ-I were administered to a random sample of 200 employees of a financial services company. Statistically significant differences were found between the groups on several of the wellness variables with the manager and White groups obtaining higher scores on these variables than their comparison groups. However, in respect of External Locus of Control, the non-manager and Black groups obtained the higher scores. Factor analytic results demonstrated that the wellness variables clustered in two correlated factors (r = 0,43 labeled psychological wellness and self-actualisation.

    We investigated if group music training in childhood is associated with prosocial skills. Children in 3rd or 4th grade who attended 10 months of music lessons taught in groups were compared to a control group of children matched for socio-economic status. All children were administered tests of prosocial skills near the beginning and end of the 10-month period. Compared to the control group, children in the music group had larger increases in sympathy and prosocial behavior, but this effect was limited to children who had poor prosocial skills before the lessons began. The effect was evident even when the lessons were compulsory, which minimized the role of self-selection. The results suggest that group music training facilitates the development of prosocial skills.

    We investigated the thermal, electrical and mechanical antinociceptive and physiological effects (heart rate, respiratory rate, arterial blood pressure, head height and abdominal auscultation score), and pharmacokinetics, of 0.5 mg/kg of the injectable formulation (ORAL) or nanoparticulated methadone (NANO) given orally, in six adult mares, using a crossover, blind and prospective design. Repeated-measure models were used to compare parametric data between and within treatments, followed by Tukey's test. Nonparametric data were analysed with Wilcoxon signed-rank, adjusted by Bonferroni tests. Blood samples were also collected up to 6 h after dosing for plasma drug quantification by LC-MS/MS. Methadone pharmacokinetic parameters were determined by noncompartmental and compartmental approaches. There were no differences in pharmacodynamic parameters. No statistical differences were observed in the pharmacokinetic parameters from noncompartmental analysis for both groups, except a significant decrease in peak plasma concentration, increase in apparent volume of distribution per fraction absorbed (Vd ss /F) and increased mean residence time (MRT) for NANO. One-compartment open model with first order elimination best described the pharmacokinetic profiles for both groups. Neither ORAL nor NANO administered orally to horses produced antinociception. The nanoencapsulated formulation of methadone given orally to horses did not improve methadone pharmacokinetic parameters or increased systemic body exposure to methadone. © 2017 John Wiley & Sons Ltd.

    To determine the efficacy and bioavailability of non-steroidal anti-inflammatory drugs (NSAIDs) when administered orally to sheep. Randomised experimental design with four treatment groups: three NSAID groups and one control group (n = 10/group). The study animals were 40 18-month-old Merino ewes with an average weight of 31.4 ± 0.5 kg. Treatment was given orally at 24 h intervals for 6 days at dose rates expected to achieve therapeutic levels in sheep: carprofen (8.0 mg/kg), ketoprofen (8.0 mg/kg) and flunixin (4.0 mg/kg). Oil of turpentine (0.1 mL) was injected into a forelimb of each sheep to induce inflammation and pain; responses (force plate pressure, skin temperature, limb circumference, haematology and plasma cortisol) were measured at 0, 3, 6, 9, 12, 24, 36, 48, 72 and 96 h post-injection. NSAID concentrations were determined by ultra-high-pressure liquid chromatography. The NSAIDs were detectable in ovine plasma 2 h after oral administration, with average concentrations of 4.5-8.4 µg/mL for ketoprofen, 2.6-4.1 µg/mL for flunixin and 30-80 µg/mL for carprofen. NSAID concentrations dropped 24 h after administration. Pain response to an oil of turpentine injection was assessed using the measures applied but no effect of the NSAIDs was observed. Although this pain model has been previously validated, the responses observed in this study differed from those in the previous study. The three NSAIDs reached inferred therapeutic concentrations in blood at 2 h after oral administration. The oil of turpentine lameness model may need further validation. © 2015 Australian Veterinary Association.

    Neonatal effects of drugs administered to mothers before delivery depend on the quantity that crosses the placental barrier, which is determined by the pharmacokinetics of the drug in the mother, fetus, and placenta. Diabetes mellitus can alter the kinetic disposition and the metabolism of drugs. This study investigated the placental transfer of lidocaine and its metabolite monoethylglycinexylidide (MEGX) in pregnant women with gestational diabetes mellitus (GDM) submitted to peridural anesthesia. A total of 10 normal pregnant women (group 1) and 6 pregnant women with GDM (group 2) were studied, all at term. The patients received 200 mg 2% lidocaine hydrochloride by the peridural locoregional route. Maternal blood samples were collected at the time of delivery and, after placental expulsion, blood samples were collected from the intervillous space, umbilical artery, and vein for determination of lidocaine and MEGX concentrations and analysis of the placental transfer of the drug. The following respective lidocaine ratios between the maternal and the fetal compartments were obtained for groups 1 and 2: umbilical vein/maternal peripheral blood, 0.60 and 0.46; intervillous space/maternal blood, 1.01 and 0.88; umbilical artery/umbilical vein, 0.77 and 0.91; and umbilical vein/intervillous space, 0.53 and 0.51. The following MEGX ratios for groups 1 and 2 were, respectively, fetal/maternal, 0.43 and 0.97; intervillous space/maternal blood, 0.64 and 0.90; umbilical artery/umbilical vein, 1.09 and 0.99; and umbilical vein/intervillous space, 0.55 and 0.78. Gestational diabetes mellitus did not affect the transplacental transfer of lidocaine but interfered with the transfer of MEGX, acting as a mechanism facilitating the transport of the metabolite. © The Author(s) 2015.

    To evaluate the analgesic efficacy of flunixin alone or in combination with diclofenac administered locally to the scrotum at the time of band castration of calves. Angus bull calves (n = 40; ≈7-9 weeks old) were allocated to four treatment groups (n = 10 per group) to examine the effects of two non-steroidal anti-inflammatory analgesics (NSAIDs) administered locally at the time of band castration: sham control; castration + flunixin; castration + flunixin + diclofenac; castration + saline. The NSAIDs and saline were administered subcutaneously into the scrotum under the band. Blood was sampled at -0.5, 0.5, 1.5, 3, 12, 24, 48 and 72 h relative to castration. Haematology parameters and plasma cortisol levels were determined in samples at all time points and plasma haptoglobin levels determined in samples collected at -0.5, 24, 48 and 72 h. Pain avoidance and postural behaviours were measured for 2 and 12 h, respectively, after castration. Band-castrated calves exhibited significantly higher peak cortisol and higher integrated cortisol responses during the first 6 h post-castration relative to sham controls. Individual active pain avoidance behaviours observed for 1 h post-castration were not significantly different between treatment groups; however; the sum of the total behaviours was significantly increased by castration (P = 0.023). Postural changes included increased abnormal ventral lying for all castrated groups and decreased normal standing and increased combined abnormal postures for the flunixin- and saline-treated groups. Growth rates of calves were not affected by treatments during weeks 1 and 2 post-castration; however, growth rates of castrated calves were significantly lower than those of sham-treated calves in week 3 post-castration (1.41 vs 0.84, 0.75 and 0.56±0.19 kg/day for sham, flunixin-, flunixin + diclofenac- and saline-treated groups, respectively).

    To assess the efficacy of intra-articular hyaluronic acid (HA) injections and exercise-based rehabilitation (EBR) programme, administered as isolated or integrated for the treatment of knee osteoarthritis. One hundred sixty-five patients affected by moderate degrees of knee OA were randomly divided into three groups. Group 1 (HA) underwent three HA injections (one every 2 weeks); group 2 (EBR) underwent 20 treatment sessions in a month of an individualized programme; and group 3 (HA + EBR) received both treatments simultaneously. Primary outcome was the Italian version of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index; secondary outcome was the evaluation of active range of movement (AROM). All patients were evaluated before and 1, 3 and 6 months after treatment. Significance was set at p injections and individualized rehabilitation programmes administered in isolation or in combination are effective in improving knee function and pain relief. The combined treatment showed the greatest pain relief at 1-month follow-up compared to either in isolation. Compared to the previous studies, this is the first study, which proposed an EBR programme tailored to the compartment of the knee joint most involved in the degenerative process. I.

    Over the course of childhood, children's thinking about social groups changes in a variety of ways. Developmental Subjective Group Dynamics (DSGD) theory emphasizes children's understanding of the importance of conforming to group norms. Abrams et al.'s study, which uses DSGD theory as a framework, demonstrates the social cognitive skills underlying young elementary school children's thinking about group norms. Future research on children's thinking about groups and group norms should explore additional elements of this topic, including aspects of typicality beyond loyalty. © 2014 The British Psychological Society.

    Engineering, administrative, and work practice controls have been recommended for many years to minimize exposure to nitrous oxide during dental procedures. To better understand the extent to which these exposure controls are used, the NIOSH Health and Safety Practices Survey of Healthcare Workers was conducted among members of professional practice organizations representing dentists, dental hygienists and dental assistants. The anonymous, modular, web-based survey was completed by 284 dental professionals in private practice who administered nitrous oxide to adult and/or pediatric patients in the seven days prior to the survey. Use of primary engineering controls (i.e., nasal scavenging mask and/or local exhaust ventilation (LEV) near the patient's mouth) was nearly universal, reported by 93% and 96% of respondents who administered to adult (A) and pediatric (P) patients, respectively. However, adherence to other recommended precautionary practices were lacking to varying degrees, and were essentially no different among those administering nitrous oxide to adult or pediatric patients. Examples of work practices which increase exposure risk, expressed as percent of respondents, included: not checking nitrous oxide equipment for leaks (41% A; 48% P); starting nitrous oxide gas flow before delivery mask or airway mask was applied to patient (13% A; 12% P); and not turning off nitrous oxide gas flow before turning off oxygen flow to the patient (8% A; 7% P). Absence of standard procedures to minimize worker exposure to nitrous oxide (13% of all respondents) and not being trained on safe handling and administration of nitrous oxide (3%) were examples of breaches of administrative controls which may also increase exposure risk. Successful management of nitrous oxide emissions should include properly fitted nasal scavenging masks, supplemental LEV (when nitrous oxide levels cannot be adequately controlled using nasal masks alone), adequate general ventilation, regular

    Full Text Available Abstract Background Patient-reported outcomes are measured in many epidemiologic studies using self- or interviewer-administered questionnaires. While in some studies differences between these administration formats were observed, other studies did not show statistically significant differences important to patients. Since the evidence about the effect of administration format is inconsistent and mainly available from cross-sectional studies our aim was to assess the effects of different administration formats on repeated measurements of patient-reported outcomes in participants with AIDS enrolled in the Longitudinal Study of Ocular Complications of AIDS. Methods We included participants enrolled in the Longitudinal Study of Ocular Complications in AIDS (LSOCA who completed the Medical Outcome Study [MOS] -HIV questionnaire, the EuroQol, the Feeling Thermometer and the Visual Function Questionnaire (VFQ 25 every six months thereafter using self- or interviewer-administration. A large print questionnaire was available for participants with visual impairment. Considering all measurements over time and adjusting for patient and study site characteristics we used linear models to compare HRQL scores (all scores from 0-100 between administration formats. We defined adjusted differences of ≥0.2 standard deviations [SD] to be quantitatively meaningful. Results We included 2,261 participants (80.6% males with a median of 43.1 years of age at enrolment who provided data on 23,420 study visits. The self-administered MOS-HIV, Feeling Thermometer and EuroQol were used in 70% of all visits and the VFQ-25 in 80%. For eight domains of the MOS-HIV differences between the interviewer- and self- administered format were Conclusions Our large study provides evidence that administration formats do not have a meaningful effect on repeated measurements of patient-reported outcomes. As a consequence, longitudinal studies may not need to consider the effect of

    Full text: While radioiodine (RI) is a well established treatment for hyperthyroidism, there is no consensus regarding the administration of fixed or calculated doses. Guidelines from scientific societies do not specify the preferable approach, nor the parameters to be used in order to calculate the latter. Therefore, the doses might, for the same patient, be different with regard to the chosen procedure. This study was undertaken to assess the variability of RI amounts administered in Belgium in various cases of hyperthyroidism. 21 Belgian nuclear medicine physicians issued from different departments and universities participated into the study. They received a file with clinical and biological data, iodine turnover rate, scintigraphic images and calculated thyroid surfaces from 10 patients (8 females, 2 males), 30-77 yrs suffering from hyperthyroidism of various etiologies: 7 patients had clinically overt hyperthyroidism and 3 subclinical hyperthyroidism; 7 patients had toxic goiters of various size (Graves' disease), 2 multi nodular goiter and 1 toxic nodule. None suffered from cardiac anomalies or ophthalmopathy. Participants were asked to define the amount of RI they would give in each case. Answers were received during a 8-week period. Analysing data from case 1 to case 10, the ranges of the proposed doses varied between 8 and 22 milli Curies (mCi) (sd : 2.4 - 6.07). Considering all the patients, the proposed doses varied between 2 mCi and 25 mCi. Analysing answers among the 21 participants, mean proposed doses varied between 4.5 and 17.3 mCi (sd: 0.69 - 7.99). Conclusion: These results demonstrate a wide variability among nuclear medicine physicians in the proposed RI doses and confirm that in Belgium there is no uniformity in the procedure used to determine the amount of RI to administer for various causes of hyperthyroidism. This emphasizes the notion that the determination of the amount of RI to be administered remains a matter of debate. (author)

    Computer-administered food frequency questionnaires (FFQs) can address limitations inherent in paper questionnaires by allowing very complex skip patterns, portion size estimation based on food pictures, and real-time error checking. We evaluated a web-based FFQ, the Graphical Food Frequency System (GraFFS). Participants completed the GraFFS, six telephone-administered 24-hour dietary recalls over the next 12 weeks, followed by a second GraFFS. Participants were 40 men and 34 women, aged 18 to 69 years, living in the Columbus, OH, area. Intakes of energy, macronutrients, and 17 micronutrients/food components were estimated from the GraFFS and the mean of all recalls. Bias (second GraFFS minus recalls) was -9%, -5%, +4%, and -4% for energy and percentages of energy from fat, carbohydrate, and protein, respectively. De-attenuated, energy-adjusted correlations (intermethod reliability) between the recalls and the second GraFFS for fat, carbohydrate, protein, and alcohol were 0.82, 0.79, 0.67, and 0.90, respectively; for micronutrients/food components the median was 0.61 and ranged from 0.40 for zinc to 0.92 for beta carotene. The correlations between the two administrations of the GraFFS (test-retest reliability) for fat, carbohydrate, protein, and alcohol were 0.60, 0.63, 0.73, and 0.87, respectively; among micronutrients/food components the median was 0.67 and ranged from 0.49 for vitamin B-12 to 0.82 for fiber. The measurement characteristics of the GraFFS were at least as good as those reported for most paper FFQs, and its high intermethod reliability suggests that further development of computer-administered FFQs is warranted.

    The purpose of this study was to investigate the effect of the co-solvents Cremophor EL and polysorbate 80 on the absorption of orally administered paclitaxel. 6 patients received in a randomized setting, one week apart oral paclitaxel 60 mg m(-2) dissolved in polysorbate 80 or Cremophor EL. For 3 patients the amount of Cremophor EL was 5 ml m(-2), for the other three 15 ml m(-2). Prior to paclitaxel administration patients received 15 mg kg(-1) oral cyclosporin A to enhance the oral absorption of the drug. Paclitaxel formulated in polysorbate 80 resulted in a significant increase in the maximal concentration (C(max)) and area under the concentration-time curve (AUC) of paclitaxel in comparison with the Cremophor EL formulations (P = 0.046 for both parameters). When formulated in Cremophor EL 15 ml m(-2), paclitaxel C(max) and AUC values were 0.10 +/- 0.06 microM and 1.29 +/- 0.99 microM h(-1), respectively, whereas these values were 0.31 +/- 0.06 microM and 2.61 +/- 1.54 microM h(-1), respectively, when formulated in polysorbate 80. Faecal data revealed a decrease in excretion of unchanged paclitaxel for the polysorbate 80 formulation compared to the Cremophor EL formulations. The amount of paclitaxel excreted in faeces was significantly correlated with the amount of Cremophor EL excreted in faeces (P = 0.019). When formulated in Cremophor EL 15 ml m(-2), paclitaxel excretion in faeces was 38.8 +/- 13.0% of the administered dose, whereas this value was 18.3 +/-15.5% for the polysorbate 80 formulation. The results show that the co-solvent Cremophor EL is an important factor limiting the absorption of orally administered paclitaxel from the intestinal lumen. They highlight the need for designing a better drug formulation in order to increase the usefulness of the oral route of paclitaxel

    Sports-related concussion has received increasing awareness due to short- and long-term neurologic sequelae seen among athletes. The King-Devick (K-D) test captures impairment of eye movements and other correlates of suboptimal brain function. We investigated the K-D test as a screening for concussion when administered by layperson sports parents in a cohort of amateur boxers. The K-D test was administered pre-fight and post-fight by laypersons masked to the head trauma status of each athlete. Matches were watched over by a ringside physician and boxing trainer. Athletes with suspected head trauma received testing with the Military Acute Concussion Evaluation (MACE) by the ringside physician to determine concussion status. Athletes sustaining concussion were compared to the athletes screened using the K-D test. Post-fight K-D scores were lower (better) than the best baseline score (41 vs. 39.3 s, P=0.34, Wilcoxon signed-rank test), in the absence of concussion. One boxer sustained a concussion as determined by the ringside physician. This boxer was accurately identified by the layperson K-D testers due to a worsening in K-D test compared to baseline (3.2 seconds) and an increased number of errors. High levels of test-retest reliability were observed (intraclass correlation coefficient 0.90 [95% CI 0.84-0.97]). Additionally, 6 boxers who participated in multiple bouts showed no worsening of their K-D times further supporting that scores are not affected by the fatigue associated with sparring. The K-D test is a rapid sideline screening tool for concussion that can be effectively administered by non-medically trained laypersons.

    To examine effects of atipamezole on detomidine midsacral subarachnoidally-induced analgesia, cardiovascular and respiratory activity, head ptosis, and position of pelvic limbs in healthy mares. 10 healthy mares. Using a randomized, blinded, crossover study design, mares received detomidine (0.03 mg/kg of body weight, diluted in 3 ml of CSF) midsacral subarachnoidally, followed by atipamezole (0.1 mg/kg [test]) or sterile saline (0.9% NaCl) solution (control), i.v. 61 minutes later and saline solution (3 ml, midsacral subarachnoidally) on a separate occasion, at least 2 weeks later. Analgesia was determined by lack of sensory perception to electrical stimulation at the perineal dermatome and no response to needle-prick stimulation extending from the coccygeal to T15 dermatomes. Arterial acid-base (pH, standard bicarbonate, and base excess values), gas tensions (PO2, PCO2), PCV, total solids concentration, heart and respiratory rates, rectal temperature, and arterial blood pressure were determined, and mares were observed for sweating and urination. Mean scores of perineal analgesia, head ptosis, position of pelvic limbs, and cardiovascular and respiratory data were compared for the 3-hour test period. Subarachnoidally administered detomidine induced perineal analgesia (mean +/- SD onset, 9.0 +/- 4.6 minutes; duration, 130 +/- 26 minutes), marked head ptosis, moderate changes in pelvic limb position, cardiovascular and respiratory depression, sweating in analgesic zones, and diuresis. Intravenously administered atipamezole significantly reduced mean scores of detomidine-induced perineal analgesia, head ptosis, pelvic limb position, sweating and diuresis; partially antagonized detomidine-induced bradycardia; and did not effect detomidine-induced bradypnea. Most effects of midsacral subarachnoidally administered detomidine, except bradycardia and bradypnea, were reversed by atipamezole (0.1 mg/kg, i.v.), indicating that most of the actions of detomidine were mediated

    The Japanese Society for Surgery of the Foot (JSSF) is developing a QOL questionnaire instrument for use in pathological conditions related to the foot and ankle. The main body of the outcome instrument (the Self-Administered Foot Evaluation Questionnaire, SAFE-Q version 2) consists of 34 questionnaire items, which provide five subscale scores (1: Pain and Pain-Related; 2: Physical Functioning and Daily Living; 3: Social Functioning; 4: Shoe-Related; and 5: General Health and Well-Being). In addition, the instrument has nine optional questionnaire items that provide a Sports Activity subscale score. The purpose of this study was to evaluate the test-retest reliability of the SAFE-Q. Version 2 of the SAFE-Q was administered to 876 patients and 491 non-patients, and the test-retest reliability was evaluated for 131 patients. In addition, the SF-36 questionnaire and the JSSF Scale scoring form were administered to all of the participants. Subscale scores were scaled such that the final sum of scores ranged between zero (least healthy) to 100 (healthiest). The intraclass correlation coefficients were larger than 0.7 for all of the scores. The means of the five subscale scores were between 60 and 75. The five subscales easily separated patients from non-patients. The coefficients for the correlations of the subscale scores with the scores on the JSSF Scale and the SF-36 subscales were all highly statistically significantly greater than zero (p valid and reliable. In the future, it will be beneficial to test the responsiveness of the SAFE-Q.

    Ciprofloxacin is commonly selected for clinical use due to its broad-spectrum efficacy and is a frequently administered antibiotic at The Marine Mammal Center, a marine mammal rehabilitation facility. Ciprofloxacin is used for treatment of California sea lions ( Zalophus californianus ) suffering from a variety of bacterial infections at doses extrapolated from other mammalian species. However, as oral absorption is variable both within and across species, a more accurate determination of appropriate dosage is needed to ensure effective treatment and avoid emergence of drug-resistant bacterial strains. A pharmacokinetic study was performed to assess plasma concentrations of ciprofloxacin in California sea lions after a single oral dose. Twenty healthy California sea lions received a single 10-mg/kg oral dose of ciprofloxacin administered in a herring fish. Blood was then collected at two of the following times from each individual: 0.5, 0.75, 1, 2, 4, 8, 10, 12, 18, and 24 hr postingestion. Plasma ciprofloxacin concentration was assessed via high-performance liquid chromatography. A population pharmacokinetics model demonstrated that an oral ciprofloxacin dose of 10 mg/kg achieved an area under the concentration vs. time curve of 6.01 μg hr/ml. Absorption was rapid, with ciprofloxacin detectable in plasma 0.54 hr after drug administration; absorption half-life was 0.09 hr. A maximum plasma concentration of 1.21 μg/ml was observed at 1.01 hr, with an elimination half-life of 3.09 hr. Ciprofloxacin administered orally at 10 mg/kg produced therapeutic antibacterial exposure for only some of the most susceptible bacterial organisms commonly isolated from California sea lions.

    Purpose The effects of particle size on the tissue distribution and excretion kinetics of silica nanoparticles and their biological fates were investigated following a single oral administration to male and female rats. Methods Silica nanoparticles of two different sizes (20 nm and 100 nm) were orally administered to male and female rats, respectively. Tissue distribution kinetics, excretion profiles, and fates in tissues were analyzed using elemental analysis and transmission electron microscopy. Results The differently sized silica nanoparticles mainly distributed to kidneys and liver for 3 days post-administration and, to some extent, to lungs and spleen for 2 days post-administration, regardless of particle size or sex. Transmission electron microscopy and energy dispersive spectroscopy studies in tissues demonstrated almost intact particles in liver, but partially decomposed particles with an irregular morphology were found in kidneys, especially in rats that had been administered 20 nm nanoparticles. Size-dependent excretion kinetics were apparent and the smaller 20 nm particles were found to be more rapidly eliminated than the larger 100 nm particles. Elimination profiles showed 7%–8% of silica nanoparticles were excreted via urine, but most nanoparticles were excreted via feces, regardless of particle size or sex. Conclusion The kidneys, liver, lungs, and spleen were found to be the target organs of orally-administered silica nanoparticles in rats, and this organ distribution was not affected by particle size or animal sex. In vivo, silica nanoparticles were found to retain their particulate form, although more decomposition was observed in kidneys, especially for 20 nm particles. Urinary and fecal excretion pathways were determined to play roles in the elimination of silica nanoparticles, but 20 nm particles were secreted more rapidly, presumably because they are more easily decomposed. These findings will be of interest to those seeking to predict

    Full Text Available Purpose: To evaluate the effects of phosphodiesterase type 5 inhibitor (PDE5i on urinary continence recovery after bilateral nerve-sparing radical prostatectomy (BNSRP. Materials and Methods: Between 2002 and 2012, 137 of 154 consecutive patients who underwent BNSRP in our institution retrospectively divided into 3 groups that included patients taking PDE5i immediately after surgery (immediate PDE5i group, n=41, patients starting PDE5i at an outpatient clinic after discharge (PDE5i group, n=56, and patients taking no medication (non-PDE5i group, n=40. Using self-administered questionnaires, the proportion of patients who did not require incontinence pads (pad-free patients was calculated preoperatively and at 1, 3, 6, 12, 18, and 24 months after BNSRP. Severity of incontinence was determined based on the pad numbers and then compared among the 3 groups. Results: Proportions of pad-free patients and severity of incontinence initially deteriorated in all of the groups to the lowest values soon after undergoing BNSRP, with gradual improvement noted thereafter. The deterioration was most prominent in the immediate PDE5i group. As compared to the non-PDE5i group, both the PDE5i and immediate PDE5i groups exhibited a better final continence status. Conclusions: PDE5i improves final continence status. However, administration of PDE5i immediately after surgery causes a distinct temporary deterioration in urinary incontinence.

    To test the reliability of dietary intake data measured with an online food frequency questionnaires (FFQ) applied to a university population by comparing the results with those from a paper and pencil version. A total of 50 students were recruited from the second-year Food Technology course at the Universitat Politècnica de València (Comunidad Valenciana, Spain) in the academic year 2008-2009. The students were between the ages of 20-32. The participants completed both presentation modes of the FFQ (paper and pencil and online) in a cross-over study with a time interval of 3-week. To study the effect of ordering of the questionnaires, participants were randomly assigned to group A (paper and pencil FFQ first) and group B (online FFQ first). Both self-administered semi-quantitative presentations of the FFQ included 84 food items divided into six groups (dairy products; eggs, meat and fish; vegetables, legumes and fruits; bread, cereals and similar; oils, fats and sweets; beverages and pre-cooked). Participants were asked how frequently and how much each food item they had consumed in the previous year. The response rate was 78% (39 students, 23% men and 77% women). For the total sample, the median dietary intakes were higher for the paper and pencil FFQ than the online version for energy (2,077 vs. 1,635 kcal/day), proteins (96 vs. 88 g/day), carbohydrates (272 vs. 211 g/day), and fat (70 vs. 58 g/day), respectively. These differences were statistically significant. However, there were not significant differences between the two presentations when the consumption by groups of food was calculated, except for "beverages and pre-cooked" group. The pilot testing showed that this online FFQ is a useful tool for estimating the intake of food groups in this university population. On the other hand, the differences found in the results of the absolute quantities of energy and nutrients intakes were not clear. These differences could be due to the problems that the

    The efficacy of perioperative probiotic administration has been reported in adults. We examined the effects of orally administered Bifidobacterium breve strain Yakult (BBG-01) on outcomes in pediatric surgical cases by assessing intestinal and blood microbiota. BBG-01 was well tolerated without adverse effects, and postoperative infectious complications were significantly decreased. Fecal analysis showed increased Bifidobacterium and decreased Enterobacteriaceae, Clostridium difficile, and Pseudomonas. Concentrations of fecal acetic acid were significantly increased, maintaining fecal pH at <7.0. The incidence of detecting bacteria in blood was significantly reduced. BBG-01 improved the intestinal environment, and may be implicated in suppressing bacterial translocation.

    Sympathoadrenergic responses during emergence and extubation can lead to an increase in heart rate (HR) and blood pressure whereas increased airway responses may lead to coughing and laryngospasm. The aim of our study was to compare the effects of lignocaine administered intravenously (IV) or intratracheally on airway and hemodynamic responses during emergence and extubation in patients undergoing elective craniotomies. Sixty patients with physical status American Society of Anaesthesiologists Classes I and II aged 18-70 years, scheduled to undergo elective craniotomies were included. The patients were randomly divided into three groups of twenty patients; Group 1 receiving IV lignocaine and intratracheal placebo (IV group), Group 2 receiving intratracheal lignocaine and IV placebo (I/T group), and Group 3 receiving IV and intratracheal placebo (placebo group). The tolerance to the endotracheal tube was monitored, and number of episodes of cough was recorded during emergence and at the time of extubation. Hemodynamic parameters such as HR and blood pressure (systolic, diastolic, mean arterial pressure) were also recorded. There was a decrease of HR in both IV and intratracheal groups in comparison with placebo group ( P < 0.005). Rise in blood pressure (systolic blood pressure, diastolic blood pressure and mean arterial pressure) was comparable in both Groups 1 and 2 but was lower in comparison with placebo group ( P < 0.005). Cough suppression was comparable in all the three groups. Grade III cough (15%) was documented only in placebo group. Both IV and intratracheal lignocaine are effective in attenuation of hemodynamic response if given within 20 min from skull pin removal to extubation. There was comparable cough suppression through intratracheal route and IV routes than the placebo group.

    To assess the short-term efficacy of a video-based cognitive behavioral therapy for insomnia (CBT-I) as compared to a professionally administered CBT-I and to a no-treatment group. Randomized controlled trial. Radio-oncology department of a public hospital affiliated with Université Laval (CHU de Québec). Two hundred forty-two women with breast cancer who had received radiation therapy in the past 18 mo and who had insomnia symptoms or were using hypnotic medications were randomized to: (1) professionally administered CBT-I (PCBT-I; n = 81); (2) video-based CBT-I (VCBT-I; n = 80); and (3) no treatment (CTL; n = 81). PCBT-I composed of six weekly, individual sessions of approximately 50 min; VCBT-I composed of a 60-min animated video + six booklets. Insomnia Severity Index (ISI) total score and sleep parameters derived from a daily sleep diary and actigraphy, collected at pretreatment and posttreatment. PCBT-I and VCBT-I were associated with significantly greater sleep improvements, assessed subjectively, as compared to CTL. However, relative to VCBT-I, PCBT-I was associated with significantly greater improvements of insomnia severity, early morning awakenings, depression, fatigue, and dysfunctional beliefs about sleep. The remission rates of insomnia (ISI insomnia (CBT-I) using a video format appears to be a valuable treatment option, but face-to-face sessions remain the optimal format for administering CBT-I efficaciously in patients with breast cancer. Self-help interventions for insomnia may constitute an appropriate entry level as part of a stepped care model. ClinicalTrials.gov Identifier: NCT00674830. Savard J, Ivers H, Savard MH, Morin CM.

    Purpose: The aim was to investigate whole-body and red marrow absorbed doses in treatments of neuroblastoma (NB) and adult neuroendocrine tumors (NETs) with {sup 131}I-metaiodobenzylguanidine and to propose a simple method for determining the activity to administer when dosimetric data for the individual patient are not available. Methods: Nine NB patients and six NET patients were included, giving in total 19 treatments as four patients were treated twice. Whole-body absorbed doses were determined from dose-rate measurements and planar gamma-camera imaging. For six NB and five NET treatments, red marrow absorbed doses were also determined using the blood-based method. Results: Dosimetric data from repeated administrations in the same patient were consistent. In groups of NB and NET patients, similar whole-body residence times were obtained, implying that whole-body absorbed dose per unit of administered activity could be reasonably well described as a power function of the patient mass. For NB, this functional form was found to be consistent with dosimetric data from previously published studies. The whole-body to red marrow absorbed dose ratio was similar among patients, with values of 1.4 ± 0.6–1.7 ± 0.7 (1 standard deviation) in NB treatments and between 1.5 ± 0.6 and 1.7 ± 0.7 (1 standard deviation) in NET treatments. Conclusions: The consistency of dosimetric results between administrations for the same patient supports prescription of the activity based on dosimetry performed in pretreatment studies, or during the first administration in a fractionated schedule. The expressions obtained for whole-body absorbed doses per unit of administered activity as a function of patient mass for NB and NET treatments are believed to be a useful tool to estimate the activity to administer at the stage when the individual patient biokinetics has not yet been measured.

    Full Text Available Abstract Background The objectives of this smoking cessation study among hospitalized smokers are to: 1 determine provider and patient receptivity, barriers, and facilitators to implementing the nurse-administered, inpatient Tobacco Tactics intervention versus usual care using face-to-face feedback and surveys; 2 compare the effectiveness of the nurse-administered, inpatient Tobacco Tactics intervention versus usual care across hospitals, units, and patient characteristics using thirty-day point prevalence abstinence at thirty days and six months (primary outcome post-recruitment; and 3 determine the cost-effectiveness of the nurse-administered, inpatient Tobacco Tactics intervention relative to usual care including cost per quitter, cost per life-year saved, and cost per quality-adjusted life-year saved. Methods/Design This effectiveness study will be a quasi-experimental design of six Michigan community hospitals of which three will get the nurse-administered Tobacco Tactics intervention and three will provide their usual care. In both the intervention and usual care sites, research assistants will collect data from patients on their smoking habits and related variables while in the hospital and at thirty days and six months post-recruitment. The intervention will be integrated into the experimental sites by a research nurse who will train Master Trainers at each intervention site. The Master Trainers, in turn, will teach the intervention to all staff nurses. Research nurses will also conduct formative evaluation with nurses to identify barriers and facilitators to dissemination. Descriptive statistics will be used to summarize the results of surveys administered to nurses, nurses’ participation rates, smokers’ receipt of specific cessation services, and satisfaction with services. General estimating equation analyses will be used to determine differences between intervention groups on satisfaction and quit rates, respectively, with

    Questionnaires can be used to assess perceived indoor air quality and symptoms in schools. Questionnaires for primary school aged children have traditionally been parent-administered, but self-administered questionnaires would be easier to administer and may yield as good, if not better, information. Our aim was to compare the repeatability of self- and parent-administered indoor air questionnaires designed for primary school aged pupils. Indoor air questionnaire with questions on child's symptoms and perceived indoor air quality in schools was sent to parents of pupils aged 7-12 years in two schools and again after two weeks. Slightly modified version of the questionnaire was administered to pupils aged 9-12 years in another two schools and repeated after a week. 351 (52%) parents and 319 pupils (86%) answered both the first and the second questionnaire. Test-retest repeatability was assessed with intra-class correlation (ICC) and Cohen's kappa coefficients (k). Test-retest repeatability was generally between 0.4-0.7 (ICC; k) in both self- and parent-administered questionnaire. In majority of the questions on symptoms and perceived indoor air quality test-retest repeatability was at the same level or slightly better in self-administered compared to parent-administered questionnaire. Agreement of self- and parent administered questionnaires was generally indoor air quality. Children aged 9-12 years can give as, or even more, repeatable information about their respiratory symptoms and perceived indoor air quality than their parents. Therefore, it may be possible to use self-administered questionnaires in future studies also with children.

  8. Vasopressin differentially modulates aggression and anxiety in adolescent hamsters administered anabolic steroids.

    Science.gov (United States)

    Morrison, Thomas R; Ricci, Lesley A; Melloni, Richard H

    2016-11-01

    Adolescent Syrian hamsters (Mesocricetus auratus) treated with anabolic/androgenic steroids display increased offensive aggression and decreased anxiety correlated with an increase in vasopressin afferent development, synthesis, and neural signaling within the anterior hypothalamus. Upon withdrawal from anabolic/androgenic steroids, this neurobehavioral relationship shifts as hamsters display decreased offensive aggression and increased anxiety correlated with a decrease in anterior hypothalamic vasopressin. This study investigated the hypothesis that alterations in anterior hypothalamic vasopressin neural signaling modulate behavioral shifting between adolescent anabolic/androgenic steroid-induced offensive aggression and anxiety. To test this, adolescent male hamsters were administered anabolic/androgenic steroids and tested for offensive aggression or anxiety following direct pharmacological manipulation of vasopressin V1A receptor signaling within the anterior hypothalamus. Blockade of anterior hypothalamic vasopressin V1A receptor signaling suppressed offensive aggression and enhanced general and social anxiety in hamsters administered anabolic/androgenic steroids during adolescence, effectively reversing the pattern of behavioral response pattern normally observed during the adolescent exposure period. Conversely, activation of anterior hypothalamic vasopressin V1A receptor signaling enhanced offensive aggression in hamsters exposed to anabolic/androgenic steroids during adolescence. Together, these findings suggest that the state of vasopressin neural development and signaling in the anterior hypothalamus plays an important role in behavioral shifting between aggression and anxiety following adolescent exposure to anabolic/androgenic steroids.

    2016-01-01

    This paper describes development of a prototype data analytics portal for analysis of accumulated screening results from eCHAT (electronic Case-finding and Help Assessment Tool). eCHAT allows individuals to conduct a self-administered lifestyle and mental health screening assessment, with usage to date chiefly in the context of primary care waiting rooms. The intention is for wide roll-out to primary care clinics, including secondary school based clinics, resulting in the accumulation of population-level data. Data from a field trial of eCHAT with sexual health questions tailored to youth were used to support design of a data analytics portal for population-level data. The design process included user personas and scenarios, screen prototyping and a simulator for generating large-scale data sets. The prototype demonstrates the promise of wide-scale self-administered screening data to support a range of users including practice managers, clinical directors and health policy analysts.

    Palliative sedation is a method of symptom management frequently used in hospices to treat uncontrolled symptoms at the end of life. There is a substantial body of literature on this subject; however, there has been little research into the experiences of hospice nurses when administering palliative sedation in an attempt to manage the terminal restlessness experienced by cancer patients. Semistructured interviews were conducted with a purposive sample of seven hospice nurses who had cared for at least one patient who had undergone palliative sedation within the past year in a hospice in the south of England in the United Kingdom. A phenomenological approach and Colaizzi's stages of analysis were employed to develop themes from the data. Facilitating a "peaceful death" was the primary goal of the nurses, where through the administration of palliative sedation they sought to enable and support patients to be "comfortable," "relaxed," and "calm" at the terminal stage of their illness. Ethical dilemmas related to decision making were a factor in achieving this. These were: medication decisions, "juggling the drugs," "causing the death," sedating young people, the family "requesting" sedation, and believing that hospice is a place where death is hastened. Hospice nurses in the U.K. frequently encounter ethical and emotional dilemmas when administering palliative sedation. Making such decisions about using palliative sedation causes general discomfort for them. Undertaking this aspect of care requires confidence and competence on the part of nurses, and working within a supportive hospice team is of fundamental importance in supporting this practice.

    The toxicity of parenterally administered vitamin E isomers, delta-tocotrienol (DT3) and gamma-tocotrienol (GT3), was evaluated in male and female CD2F1 mice. In an acute toxicity study, a single dose of DT3 or GT3 was administered subcutaneously in a dose range of 200 to 800 mg/kg. A mild to moderately severe dermatitis was observed clinically and microscopically in animals at the injection site at doses above 200 mg/kg. The severity of the reaction was reduced when the drug concentration was lowered. Neither drug produced detectable toxic effects in any other tissue at the doses tested. Based on histopathological analysis for both DT3 and GT3, and macroscopic observations of inflammation at the injection site, a dose of 300 mg/kg was selected as the lowest toxic dose in a 30-day toxicity study performed in male mice. At this dose, a mild skin irritation occurred at the injection site that recovered completely by the end of the experimental period. At a dose of 300 mg/kg of DT3 or GT3, no adverse effects were observed in any tissues or organs. © The Author(s) 2014.

    Full Text Available Nanoparticles have been extensively developed for therapeutic and diagnostic applications. While the focus of nanoparticle trafficking in vivo has traditionally been on drug delivery and organ-level biodistribution and clearance, recent work in cancer biology and infectious disease suggests that targeting different cells within a given organ can substantially affect the quality of the immunological response. Here, we examine the cell-level biodistribution kinetics after administering ultrasmall Pluronic-stabilized poly(propylene sulfide nanoparticles in the mouse. These nanoparticles depend on lymphatic drainage to reach the lymph nodes and blood, and then enter the spleen rather than the liver, where they interact with monocytes, macrophages and myeloid dendritic cells. They were more readily taken up into lymphatics after intradermal (i.d. compared to intramuscular administration, leading to ∼50% increased bioavailability in blood. When administered i.d., their distribution favored antigen-presenting cells, with especially strong targeting to myeloid cells. In tumor-bearing mice, the monocytic and the polymorphonuclear myeloid-derived suppressor cell compartments were efficiently and preferentially targeted, rendering this nanoparticulate formulation potentially useful for reversing the highly suppressive activity of these cells in the tumor stroma.

    Depression is common in individuals with multiple sclerosis (MS). While psychotherapy is an effective treatment for depression, not all individuals benefit. We examined whether baseline social support might differentially affect treatment outcome in 127 participants with MS and depression randomized to either Telephone-administered Cognitive-Behavioral Therapy (T-CBT) or Telephone-administered Emotion-Focused Therapy (T-EFT). We predicted that those with low social support would improve more in T-EFT, since this approach emphasizes the therapeutic relationship, while participants with strong social networks and presumably more emotional resources might fare better in the more structured and demanding T-CBT. We found that both level of received support and satisfaction with that support at baseline did moderate treatment outcome. Individuals with high social support showed a greater reduction in depressive symptoms in the T-CBT as predicted, but participants with low social support showed a similar reduction in both treatments. This suggests that for participants with high social support, CBT may be a more beneficial treatment for depression compared with EFT.

    Full Text Available Abstract Background Self report of smoking status is potentially unreliable in certain situations and in high-risk populations. This study aimed to determine the accuracy and acceptability of computer administered self-report of smoking status among a low socioeconomic (SES population. Methods Clients attending a community service organisation for welfare support were invited to complete a cross-sectional touch screen computer health survey. Following survey completion, participants were invited to provide a breath sample to measure exposure to tobacco smoke in expired air. Sensitivity, specificity, positive predictive value and negative predictive value were calculated. Results Three hundred and eighty three participants completed the health survey, and 330 (86% provided a breath sample. Of participants included in the validation analysis, 59% reported being a daily or occasional smoker. Sensitivity was 94.4% and specificity 92.8%. The positive and negative predictive values were 94.9% and 92.0% respectively. The majority of participants reported that the touch screen survey was both enjoyable (79% and easy (88% to complete. Conclusions Computer administered self report is both acceptable and accurate as a method of assessing smoking status among low SES smokers in a community setting. Routine collection of health information using touch-screen computer has the potential to identify smokers and increase provision of support and referral in the community setting.

    Sulfonylureas are widely used as an antidiabetic drug. In the present study, the effects of sulfonylurea administered supraspinally on immobilization stress-induced blood glucose level were studied in ICR mice. Mice were once enforced into immobilization stress for 30 min and returned to the cage. The blood glucose level was measured 30, 60, and 120 min after immobilization stress initiation. We found that intracerebroventricular (i.c.v.) injection with 30 µg of glyburide, glipizide, glimepiride or tolazamide attenuated the increased blood glucose level induced by immobilization stress. Immobilization stress causes an elevation of the blood corticosterone and insulin levels. Sulfonylureas pretreated i.c.v. caused a further elevation of the blood corticosterone level when mice were forced into the stress. In addition, sulfonylureas pretreated i.c.v. alone caused an elevation of the plasma insulin level. Furthermore, immobilization stress-induced insulin level was reduced by i.c.v. pretreated sulfonylureas. Our results suggest that lowering effect of sulfonylureas administered supraspinally against immobilization stress-induced increase of the blood glucose level appears to be primarily mediated via elevation of the plasma insulin level.

    The decarboxylation product of arginine, agmatine, has effectively reduced or prevented opioid-induced tolerance and dependence when given either systemically (intraperitoneally or subcutaneously) or centrally (intrathecally or intracerebroventricularly). Systemically administered agmatine also reduces the escalation phase of intravenous fentanyl self-administration in rats. The present study assessed whether centrally (intracerebroventricular, i.c.v.) delivered agmatine could prevent the development of fentanyl self-administration in mice. Mice were trained to respond under a fixed-ratio 1 (FR1) schedule for either fentanyl (0.7 μg/70 μl, p.o.) or food reinforcement. Agmatine (10 nmol/5 μl), injected i.c.v. 12-14h before the first session and every other evening (12-14h before session) for 2 weeks, completely attenuated oral fentanyl self-administration (but not food-maintained responding) compared to saline-injected controls. When agmatine was administered after fentanyl self-administration had been established (day 8) it had no attenuating effects on bar pressing. This dose of agmatine does not decrease locomotor activity as assessed by rotarod. The present findings significantly extend the previous observation that agmatine prevents opioid-maintained behavior to a chronic model of oral fentanyl self-administration as well as identifying a supraspinal site of action for agmatine inhibition of drug addiction.

    Full Text Available Objectives: Higher rate of slime production has been found in pathogen bacteria strains. Accordingly, the factors thatcontribute to higher slime production rate increase the infection risk, while the factors that reduce the slime productionrate will reduce the infection risk. The effect of some drugs that are administered through catheters in intensive careunits on slime production with coagulase negative Staphylococci was investigated.Materials and methods: In this study, the effect of four different preparations containing Glyceryl trinitrate (Perlinganit®, Dexmedetomidine (Precedex®, Esmolol (Brevibloc®, and Propofol (Propofol® on slime production of 24Staphylococcus epidermidis strains isolated from blood cultures of patients, and reference strain were investigated. Slimeproduction was determined using ‘the quantitative microdilution plaque test’ described by Christensen.Results: Under controlled medium, eight strains formed slimes, and in the media containing esmolol, glyceryl trinitrate,dexmedetomidine, and propofol slimes were positive for five, 21, 15, and 18 strains, respectively. The rate of slime productionin glyceryl trinitrate, dexmedetomidine, and propofol containing media were higher than that of the controls.Conclusions: In the light of the results of this study, it is concluded that the drugs and/or additives increase the rate ofslime production. The effects of the preparations administered through catheters on slime production should be investigated,and these effects should be kept in mind during their use.

    The aims of this study were to identify all available self-administered instruments measuring health literacy in people with diabetes and to determine the current instrument that is the most appropriate for applying to this population in both practice and research. A systematic review of measurement properties. MEDLINE, EMBASE and CINAHL electronic databases from their inception up to 28 March 2016. The methodological quality of each included study was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments checklist. The reported results for measurement properties in the studies were assessed according to Terwee's quality criteria. Thirteen self-administered instruments measuring health literacy in people with diabetes were identified, of which six (44%) were diabetes-specific instruments. The instruments that covered the broadest contents of health literacy were the Health Literacy Scale and Health Literacy Questionnaire. The (test-retest) reliability, measurement error and responsiveness were not evaluated for any instrument, while internal consistency and hypothesis testing validity were the most frequently assessed measurement properties. With the current evidence, the Health Literacy Scale may be the most appropriate instrument for patients with diabetes in practice and research. However, the structural validity of this scale needs to be further established, particularly in other language versions. It is also recommended to use the Diabetes Numeracy Test-15 along with the Health Literacy Scale to complement the lack of numeracy measures in the Health Literacy Scale. © 2017 John Wiley & Sons Ltd.

  20. The problem of bias when nursing facility staff administer customer satisfaction surveys.

    Customer satisfaction instruments are being used with increasing frequency to assess and monitor residents' assessments of quality of care in nursing facilities. There is no standard protocol, however, for how or by whom the instruments should be administered when anonymous, written responses are not feasible. Researchers often use outside interviewers to assess satisfaction, but cost considerations may limit the extent to which facilities are able to hire outside interviewers on a regular basis. This study was designed to investigate the existence and extent of any bias caused by staff administering customer satisfaction surveys. Customer satisfaction data were collected in 1998 from 265 residents in 21 nursing facilities in North Dakota. Half the residents in each facility were interviewed by staff members and the other half by outside consultants; scores were compared by interviewer type. In addition to a tabulation of raw scores, ordinary least-squares analysis with facility fixed effects was used to control for resident characteristics and unmeasured facility-level factors that could influence scores. Significant positive bias was found when staff members interviewed residents. The bias was not limited to questions directly affecting staff responsibilities but applied across all types of issues. The bias was robust under varying constructions of satisfaction and dissatisfaction. A uniform method of survey administration appears to be important if satisfaction data are to be used to compare facilities. Bias is an important factor that should be considered and weighed against the costs of obtaining outside interviewers when assessing customer satisfaction among long term care residents.

    Experiments were performed to investigate the effect of ascorbic acid (AA) in reducing hemato-biochemical changes in pack donkeys during the cold-dry (harmattan) season. Six experimental donkeys administered orally AA (200 mg/kg) and six control donkeys not administered ascorbic acid were subjected to packing. Blood samples were collected from all donkeys for hematological and biochemical analyses. In the control donkeys, packed cell volume (PCV), erythrocyte count and hemoglobin concentration (Hb) decreased significantly (Pdonkeys, there was no significant difference between the pre- and post-packing values of PCV, erythrocyte count and Hb. In the control donkeys, the neutrophil and neutrophil:lymphocyte ratio increased significantly (Pdonkeys, the pre- and post-packing values were not significantly different. The eosinophil count increased significantly (Pdonkeys post packing. In conclusion, packing exerted significant adverse effects on the hematological parameters ameliorated by AA administration. AA may modulate neutrophilia and induce a considerable alteration of erythroid markers in donkeys subjected to packing during the harmattan season.

    The objective of the study was to determine the absorption, bioavailability and sedative effect of detomidine administered to horses as an oromucosal gel compared to intravenous and intramuscular administration of detomidine injectable solution. The study was open and randomized, with three sequences crossover design. Nine healthy horses were given 40 μg/kg detomidine intravenously, intramuscularly or administered under the tongue with a 7-day wash-out period between treatments. Blood samples were collected before and after drug administration for the measurement of detomidine concentrations in serum. The effects of the route of administration on heart rate and rhythm were evaluated and the depth of sedation assessed. Mean (±SD) bioavailability of detomidine was 22% (±5.3%) after sublingual administration and 38.2% (±7.9%) after intramuscular administration. The sedative effects correlated with detomidine concentrations regardless of the route of administration. We conclude that less detomidine is absorbed when given sublingually than when given intramuscularly, because part of it does not reach the circulation. Sublingual administration of detomidine oromucosal gel at 40 μg/kg produces safe sedation in horses. Slow absorption leads to fewer and less pronounced adverse effects than the more rapid absorption after intramuscular injection. © 2010 Blackwell Publishing Ltd.

    The popularity of St. John's wort (Hypericum perforatum) for the treatment of depression is increasing and, in recent years, concerns about its use during pregnancy and breastfeeding have emerged. The purpose of this study was to investigate, in Wistar rats, the effects of a treatment with hypericum administered prenatally and during breastfeeding (from 2 weeks before mating to 21 days after delivery). Two doses of the extract were chosen, 100 mg/kg per day, which, based on surface area, is comparable to the dose administered to humans, and 1000 mg/kg per day. A microscopical analysis of livers, kidneys, hearts, lungs, brains, and small bowels was performed. A severe damage was observed in the livers and kidneys of animals euthanized postnatally on days 0 and 21. The lesions were more severe with the higher dose and in animals that were breastfed for 21 days; however, an important renal and hepatic damage was evident also with the dose of 100 mg/kg per day. In addition, similar serious hepatic and renal lesions were evident also in animals that were exposed to hypericum only during breastfeeding. In particular, a focal hepatic damage, with vacuolization, lobular fibrosis, and disorganization of hepatic arrays was evident; in the kidney, a reduction in glomerular size, disappearance of Bowman's space, and hyaline tubular degeneration were found. The results obtained in this study indicate that further, appropriate histological studies should be performed in other animal species to better evaluate the safety of hypericum extracts taken during pregnancy and breastfeeding

    The worldwide use of Nuclear Medicine diagnostic procedures and the tendency to its increment, infers an important exposure of the population to ionising radiation; it has motivated that the IAEA in the International Basic Safety Standards (BSS), emits recommendations for the establishment of guidance levels of activities administered to the patients in diagnostic procedures. Taking into account the above-mentioned and that in Cuba there exist 20 departments of Nuclear Medicine that in the majority possess equipment with more than 20 years of operation, which influences directly the medical exposure. A survey was designed and applied in 10 of these departments. The survey evaluates the compliance with the BSS requirements, and specifically, the activities administered to the patients in Nuclear Medicine diagnostic procedures are analysed. In the present work the obtained preliminary results of the statistical analysis carried out on the activity values used in Nuclear Medicine departments are presented, and comparisons made for a proposal of guidance levels for the national practice, which is compared with those recommended internationally.

    Full Text Available Proteoglycan (PG extracted from salmon nasal cartilage has potential to be a prophylactic agent. Daily oral administration of the PG attenuates systemic inflammatory response in the experimental mouse models. In this study, we applied the culture-independent approach to investigate an alteration of intestinal microbiota composition in PG-administered mice. The results indicated that the population level of bacilli increased in the small and large intestine upon PG administration. On the other hand, the population level of clostridia decreased in the large intestine. The proportion of bacteria that are able to ferment saccharides and produce short-chain fatty acids increased in the small intestine and decreased in the large intestine. Importantly, population level of probiotic lactobacilli and bacteria exhibiting the immunomodulatory effect increased in the PG-administered mice. In addition, several disease-associated bacteria decreased upon PG administration. These results provided an understanding of the specific role of PG involved in host immune modulation and supported our hypothesis that daily oral administration of PG improves the overall balance in composition of the intestinal microbial community.

    Accurately recording vaccine lot number, expiration date, and product identifiers, in patient records is an important step in improving supply chain management and patient safety in the event of a recall. These data are being encoded on two-dimensional (2D) barcodes on most vaccine vials and syringes. Using electronic vaccine administration records, we evaluated the accuracy of lot number and expiration date entered using 2D barcode scanning compared to traditional manual or drop-down list entry methods. We analyzed 128,573 electronic records of vaccines administered at 32 facilities. We compared the accuracy of records entered using 2D barcode scanning with those entered using traditional methods using chi-square tests and multilevel logistic regression. When 2D barcodes were scanned, lot number data accuracy was 1.8 percentage points higher (94.3-96.1%, Pmanufacturer, month vaccine was administered, and vaccine type were associated with variation in accuracy for both lot number and expiration date. Two-dimensional barcode scanning shows promise for improving data accuracy of vaccine lot number and expiration date records. Adapting systems to further integrate with 2D barcoding could help increase adoption of 2D barcode scanning technology. Published by Elsevier Ltd.

    Caregiving can be stressful, potentially creating physical and psychological strain. Substantial evidence has shown that family caregivers suffer from significant health problems arising from the demands of caregiving. Although there are programs supporting caregivers, there is little evidence regarding their effectiveness. Acupressure is an ancient Chinese healing method designed to restore the flow of Qi (vital energy) by applying external pressure to acupoints. A randomized, wait-list controlled trial was developed to evaluate the effectiveness of a self-administered acupressure intervention on caregiver stress (primary objective) and stress-related symptoms of fatigue, insomnia, depression, and health-related quality of life (secondary objectives) in Chinese caregivers of older family members. Two hundred Chinese participants, aged ≥ 21 years, who are the primary caregivers of an older family member and screen positive for caregiver stress and symptoms of fatigue/insomnia/depression will be recruited from a community setting in Hong Kong. Subjects will be randomized to receive either an immediate treatment condition (self-administered acupressure intervention) or a wait-list control condition. The self-administered acupressure intervention will include (i) an individual learning and practice session twice a week for 2 weeks, (ii) a home follow-up visit once a week for 2 weeks, and (iii) 15-min self-practice twice a day for 6 weeks. The wait-list control group will receive the same acupressure training after the intervention group has completed the intervention. We hypothesize that Chinese family caregivers in the intervention group will have lower levels of caregiver stress, fatigue, insomnia, depression, and higher health-related quality of life after completion of the intervention than participants in the wait-list control group. This study will provide evidence for the effectiveness of self-administered acupressure in reducing stress and improving

    Full Text Available Aim: To evaluate the effect of long-term use of silibinin, epigallocatechin (ECGC, quercetin and rutin on the absorption and tissue distribution of metformin and atenolol. Materials and Methods: Thirty male rats were used, allocated into 5 groups and treated as follow: 1st group treated with olive oil and served as control; the other 4 groups were treated with either silibinin, EPGC, quercetin or rutin, administered orally as oily solutions for 30 days. At day 30, a 300mg/kg metformin and 50mg/kg atenolol were administered orally; 3.0 hrs later, the animals were sacrificed and blood samples, tissues of brain, kidney and liver were obtained for evaluation of the drugs level. Results: The polyphenols increased both serum and tissue levels of metformin compared with controls. This effect was relatively varied according to the structural differences among flavonoids. Conclusion: Long-term use of supraphysiological doses of flavonoids increase absorption of Zn, Cu and Fe and their tissue availability in brain, kidney and liver; this effect seems to be different with variations in structural features.

    Full Text Available Introduction. There are increasing interests about pharmacotherapy in depressed children and adolescents. Althought TCAs (such as imipramine are approved for use in enuresis and ADHD, but controlled studies have failed to demonstrate efficacy of them over placebo in the treatment of depressive disorders in both children or adolescents. On the other hand, a relatively more amount of studies address SSRls (such as fluoxetine, as the drug of choice for treatment of depressed children and adolescents, because of theire effectiveness and safety.
    Methods. In this retrospective study, 306 depressed child and adolescent (7-18 year old who admitted to a psychiatric out patient clinic were studied (196 male and 110 female. Imipramine and fluoxetin were administered for 47 percent and 43 percent of cases, respectively.
    Results. In imipramin geoup and fluoxetine group the symptoms of 126 (87 percent and 102 (77 percent patient was improved, respectively. The frequency of side effects was 21 percent for imipramin (specialy sedation, dizziness and palpitation and 22 percent for fluoxatine (specially headache, insomnia and agitation.
    Discussion. This study suggests that both imipramin and fluoxetine are efficient for tratment of children and adolescents depression. However, because of high theraputic index of fluoxetine, this drug may be a better choice.

    The fate of [4- 14 C]-cholesterol administered intraperitoneally or orally was compared in exercised (treadmill running for 14 days) and sedentary rats. Plasma triglyceride, phospholipid and cholesterol decreased in exercised rats and this reduction lasted at least for 10 days after exercise was terminated. When rats received [4- 14 C]-cholesterol intraperitoneally or orally, the turnover rate of serum cholesterol was considerably higher in exercised rats at the time shortly after the administration of the label. The radioactivity remaining in the liver was consistently lower in exercised rats, whereas that in extrahepatic tissues was the same between two groups. Excretion into feces of the label as total steroids was moderately enhanced by exercise. This effect was almost entirely ascribed to the increase in output of the label shortly after the administration. These results suggest that the mechanism responsible for cholesterol lowering effect of exercise is mainly attributable to the increase in turnover of cholesterol in the hepato-plasmic system. The moderate increase in fecal output of endogenous steroids may be the reflection of the increased turnover. (author)

    2012-02-01

    Full Text Available Abstract Background Internet-administered cognitive behavioural therapy (ICBT has been found to be effective for a range of anxiety disorders. However, most studies have focused on one specific primary diagnosis and co-morbidity has not been considered. In primary care settings, patients with anxiety often suffer from more than one psychiatric condition, making it difficult to disseminate ICBT for specific conditions. The aim of this study will be to investigate if ICBT tailored according to symptom profile can be a feasible treatment for primary care patients with anxiety disorders. It is a randomised controlled trial aimed to evaluate the treatment against an active control group. Methods Participants with anxiety disorders and co-morbid conditions (N = 128, will be recruited from a primary care population. The Clinical Outcome in Routine Evaluation (CORE-OM will serve as the primary outcome measure. Secondary measures include self-reported depression, anxiety, quality of life and loss of production and the use of health care. All assessments will be collected via the Internet and measure points will be baseline, post treatment and 12 months post treatment. Discussion This trial will add to the body of knowledge on the effectiveness of ICBT for anxiety disorders in primary care. The trial will also add knowledge on the long term effects of ICBT when delivered for regular clinic patients Trial Registration ClinicalTrials.gov: NCT01390168

    Older adults taking multiple prescription and nonprescription drugs are at risk for medication use problems, yet there are few brief, self-administered screening tools designed specifically for them. The study objective was to develop and validate a patient-centered screener for community-dwelling older adults. In phase 1, a convenience sample of 57 stakeholders (older adults, pharmacists, nurses, and physicians) participated in concept mapping, using Concept System® Global MAX TM , to identify items for a questionnaire. In phase 2, a 40-item questionnaire was tested with a convenience sample of 377 adults and a 24-item version was tested with 306 older adults, aged 55 and older, using Rasch methodology. In phase 3, stakeholder focus groups provided feedback on the format of questionnaire materials and recommended strategies for addressing problems. The concept map contained 72 statements organized into 6 conceptual clusters or domains. The 24-item screener was unidimensional. Cronbach's alpha was .87, person reliability was acceptable (.74), and item reliability was high (.96). The MedUseQ is a validated, patient-centered tool targeting older adults that can be used to assess a wide range of medication use problems in clinical and community settings and to identify areas for education, intervention, or further assessment.

    Mango (Mangifera indica L.) stem bark aqueous extract (MSBE) is a new natural product with antioxidant, anti-inflammatory and immunomodulatory effects known by the brand name of its formulations as Vimang. Previously, the oral toxicity studies of the extract showed a low toxicity potential up to 2000 mg/kg. This work reports the results about teratogenic and genotoxicologic studies of MSBE. For embryotoxicity study, MSBE (20, 200, or 2000 mg/kg/day) was given to Sprague-Dawley rats by gavage on days 6-15 of gestation. For genotoxicity, MSBE was administered three times during 48 h to NMRI mice. Cyclophosphamide (50 mg/kg) was used as a positive control. No maternal or developmental toxicities were observed when the rats were killed on day 20th. The maternal body-weight gain was not affected. No dose-related effects were observed in implantations, fetal viability or external fetal development. Skeletal and visceral development was similar among fetuses from all groups. No genotoxicity was observed in bone marrow erythrocytes and liver cells after administration. MSBE appears to be neither embryotoxic nor genotoxic as measured by bone marrow cytogenetics in rodents.

    Full Text Available This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1+1+16=18 families of finite simple groups, as an introduction to the sporadic groups. These are described next, in three levels of increasing complexity, plus the six isolated ''pariah'' groups. The (old five Mathieu groups make up the first, smallest order level. The seven groups related to the Leech lattice, including the three Conway groups, constitute the second level. The third and highest level contains the Monster group M, plus seven other related groups. Next a brief mention is made of the remaining six pariah groups, thus completing the 5+7+8+6=26 sporadic groups. The review ends up with a brief discussion of a few of physical applications of finite groups in physics, including a couple of recent examples which use sporadic groups.

    Sodium 4-phenylbutyrate (PBA) exerts therapeutic effects in a wide range of pathologies. A previous study by the present authors revealed that intraperitoneal administration of PBA suppresses the onset of dextran sulfate sodium (DSS)-induced colitis in mice. In the present study, the effects of orally administered PBA are investigated, as this route of administration is more clinically relevant. The therapeutic efficacy of PBA (10 mg/12 h) in mice with experimental colitis was assessed based on the disease activity index, production of inflammatory cytokines, colon length and histopathological investigations. The results of the present study demonstrated a significantly higher survival rate in the PBA-treated group compared with the PBA-untreated (DSS control) group (P=0.0156). PBA treatment improved pathological indices of experimental colitis (P<0.05). Furthermore, the oral administration of PBA significantly inhibited the DSS-induced shortening of the colon (P<0.05) and overproduction of interleukin (IL)-1β and IL-6 (both P<0.05) as measured in colonic lavage fluids. A marked attenuation of the DSS-induced overproduction of tumor necrosis factor was also observed. For histopathological analysis, a marked decrease in mature goblet cells and increase in enlarged nuclei of the absorptive cells was observed in colon lesions of DSS control mice as compared with normal untreated mice. However, in the PBA-treated mice, no such lesions were observed and the mucosa resembled that of DSS-untreated mice. The results of the present study, combined with those results of a previous study, suggest that oral and intraperitoneal administration of PBA have similar preventative effects on DSS-induced colitis, achieved by suppressing its pathogenesis.

    The Inflammatory bowel disease (IBD) Disability Index is a validated tool that evaluates functional status; however, it is used mainly in the clinical trial setting. We describe the use of an iterative Delphi consensus process to develop the IBD Disk-a shortened, self-administered adaption of the validated IBD Disability Index-to give immediate visual representation of patient-reported IBD-related disability. In the preparatory phase, the IBD CONNECT group (30 health care professionals) ranked IBD Disability Index items in the perceived order of importance. The Steering Committee then selected 10 items from the IBD Disability Index to take forward for inclusion in the IBD Disk. In the consensus phase, the items were refined and agreed by the IBD Disk Working Group (14 gastroenterologists) using an online iterative Delphi consensus process. Members could also suggest new element(s) or recommend changes to included elements. The final items for the IBD Disk were agreed in February 2016. After 4 rounds of voting, the following 10 items were agreed for inclusion in the IBD Disk: abdominal pain, body image, education and work, emotions, energy, interpersonal interactions, joint pain, regulating defecation, sexual functions, and sleep. All elements, except sexual functions, were included in the validated IBD Disability Index. The IBD Disk has the potential to be a valuable tool for use at a clinical visit. It can facilitate assessment of inflammatory bowel disease-related disability relevant to both patients and physicians, discussion on specific disability-related issues, and tracking changes in disease burden over time.

Methods: Silica nanoparticles of two different sizes (20 nm and 100 nm were orally administered to male and female rats, respectively. Tissue distribution kinetics, excretion profiles, and fates in tissues were analyzed using elemental analysis and transmission electron microscopy. Results: The differently sized silica nanoparticles mainly distributed to kidneys and liver for 3 days post-administration and, to some extent, to lungs and spleen for 2 days post-administration, regardless of particle size or sex. Transmission electron microscopy and energy dispersive spectroscopy studies in tissues demonstrated almost intact particles in liver, but partially decomposed particles with an irregular morphology were found in kidneys, especially in rats that had been administered 20 nm nanoparticles. Size-dependent excretion kinetics were apparent and the smaller 20 nm particles were found to be more rapidly eliminated than the larger 100 nm particles. Elimination profiles showed 7%–8% of silica nanoparticles were excreted via urine, but most nanoparticles were excreted via feces, regardless of particle size or sex. Conclusion: The kidneys, liver, lungs, and spleen were found to be the target organs of orally-administered silica nanoparticles in rats, and this organ

    BACKGROUND: Infliximab is usually administered by two monthly intravenous (iv) infusions, therefore requiring visits to hospital. Adalimumab is administered by self subcutaneous (sc) injections every other week. Both of these anti-TNF drugs appear to be equally efficacious in the treatment of Crohn\\'s Disease and therefore the decision regarding which drug to choose will depend to some extent on patient choice, which may be based on the mode of administration.The aims of this study were to compare preferences in Inflammatory Bowel Disease (IBD) patients for two currently available anti-TNF agents and the reasons for their choices. METHODS: An anonymous questionnaire was distributed to IBD patients who had attended the Gastroenterology service (Ulster Hospital, Dundonald, Belfast, N. Ireland. UK) between January 2007 and December 2007. The patients were asked in a hypothetical situation if the following administering methods of anti-TNF drugs (intravenous or subcutaneous) were available, which drug route of administration would they choose. RESULTS: One hundred and twenty-five patients fulfilled the inclusion criteria and were issued questionnaires, of these 78 questionnaires were returned (62 percent response). The mean age of respondent was 44 years. Of the total number of respondents, 33 patients (42 percent) preferred infliximab and 19 patients (24 percent) preferred adalimumab (p = 0.07). Twenty-six patients (33 percent) did not indicate a preference for either biological therapy and were not included in the final analysis. The commonest reason cited for those who chose infliximab (iv) was: "I do not like the idea of self-injecting," (67 percent). For those patients who preferred adalimumab (sc) the commonest reason cited was: "I prefer the convenience of injecting at home," (79 percent). Of those patients who had previously been treated with an anti-TNF therapy (n = 10, all infliximab) six patients stated that they would prefer infliximab if given the choice

    The aim of this study was to determine the stability of commercially available eribulin mesylate containing injection solution as well as diluted ready-to-administer solutions stored under refrigeration or at room temperature. Stability was studied by a novel developed stability-indicating reversed-phase high-performance liquid chromatography (RP-HPLC) assay with ultraviolet detection (detection wavelength 200 nm). Triplicate test solutions of eribulin mesylate containing injection concentrate (0.5 mg/mL) and with 0.9% sodium chloride solution diluted ready-to-administer preparations (0.205 mg/mL eribulin mesylate in polypropylene (PP) syringes, 0.020 mg/mL eribulin mesylate in polypropylene/polyethylene (PE) bags) were stored protected from light either at room temperature (25) or under refrigeration (2-8). Samples were withdrawn on day 0 (initial), 1, 3, 5, 7, 14, 21 and 28 of storage and assayed. Physical stability was determined by measuring the pH value once a week and checking for visible precipitations or colour changes. The stability tests revealed that concentrations of eribulin mesylate remained unchanged over a period of 28 days irrespective of concentration, container material or storage temperature. Neither colour changes nor visible particles have been observed. The pH value varied slightly over time but remained in the stability favourable range of 5-9. Eribulin mesylate injection (0.5 mg/mL) is physico-chemically stable over a period of 28 days after first puncture of the vial. After dilution with 0.9% NaCl vehicle solution, ready-to-administer eribulin mesylate injection solutions (0.205 mg/mL in PP syringe) and infusion solutions (0.02 mg/mL in prefilled PP/PE bags) are physico-chemically stable for a period of at least four weeks either refrigerated or stored at room temperature. For microbiological reasons storage under refrigeration is recommended.

    Full text: Therapeutic doses of I-131 for treatment of thyroid cancer are administered orally in liquid or capsule form. During the last few years, a total number of patients loaded in our isolation ward increased from 4 to 10 patients per week. When considering radiation safety precautions for attending technologists, it is preferable to use the dose in capsules. The purpose of this study is to compare radiation exposure to nuclear medicine technologists from administering I-131 therapy dosages in capsules and in liquid form in a closed system. Materials and Methods: Three year radiation exposure to technologists during I-131 administration was analyzed. From January 2004 to June 2005 dose administration was in liquid form (n=263) and from July 2005 to February 2007 in capsules (n=541). Radiation dose assessment was performed with an electronic personal dosimeter (PDM 112). The dose rate in μSv and time spent per patient were recorded. Results: Dose received per patient when I-131 was given in a liquid was 3.50 ± 1.67 μSv and 1.17 ± 0.66 μSv when given in capsules. Compared with the use of a liquid, capsules significantly reduced radiation dose to technologists by 66% (P < 0.001). These doses received depended not only on the administered activity but also on the time, distance and shielding. Time spent per patient, including a brief visit before the time of dosing to explain the procedure and answer questions was reduced slightly from 4.4 ± 2.2 to 3.7 ± 1.8 minutes (P < 0.01). These correspond to a reduction in a yearly dose to 1 technologist by 40%, from 0.63 mSv to 0.38 mSv from dosing to 175 and 325 patients respectively. Conclusions: The measured doses clearly showed that handling of I-131 therapy dosages either in a liquid form or capsules are not the major contributors to the technologist's radiation exposure in routine clinical practice. However, one has to be cautious and follow good work practice to avoid risk of radiation exposure and radioiodine

    Previous research conducted in November 2013 found there were a limited number of states and territories in the United States (US) that authorize emergency medical technicians (EMTs) and emergency medical responders (EMRs) to administer opioid antagonists. Given the continued increase in the number of opioid-related overdoses and deaths, many states have changed their policies to authorize EMTs and EMRs to administer opioid antagonists. The goal of this study is to provide an updated description of policy on EMS licensure levels' authority to administer opioid antagonists for all 50 US states, the District of Columbia (DC), and the Commonwealth of Puerto Rico (PR). State law and scopes of practice were systematically reviewed using a multi-tiered approach to determine each state's legally-defined EMS licensure levels and their authority to administer an opioid antagonist. State law, state EMS websites, and state EMS scope of practice documents were identified and searched using Google Advanced Search with Boolean Search Strings. Initial results of the review were sent to each state office of EMS for review and comment. As of September 1, 2017, 49 states and DC authorize EMTs to administer an opioid antagonist. Among the 40 US jurisdictions (39 states and DC) that define the EMR or a comparable first responder licensure level in state law, 37 states and DC authorize their EMRs to administer an opioid antagonist. Paramedics are authorized to administer opioid antagonists in all 50 states, DC, and PR. All 49 of the US jurisdictions (48 states and DC) that define the advanced emergency medical technician (AEMT) or a comparable intermediate EMS licensure level in state law authorize their AEMTs to administer an opioid antagonist. 49 out of 52 US jurisdictions (50 states, DC, and PR) authorize all existing levels of EMS licensure levels to administer an opioid antagonist. Expanding access to this medication can save lives, especially in communities that have limited

  5. Calculation of radiation exposures from patients to whom radioactive materials have been administered

    Cormack, John; Shearer, Jane

    1998-03-01

    Spreadsheet templates which calculate cumulative exposures to other persons from patients to whom radioactive materials have been administered have been developed by the authors. Calculations can be based on any specified single-, bi- or tri-exponential whole-body clearance rate and a diurnal (or any other periodic) contact pattern. The time (post-administration) during which close contact should be avoided in order to constrain the radiation exposure and exposure rates to selected limits is also calculated using an iterative technique (Newton's method), and the residual activity at the time when contact can resume is also calculated. These templates find particular application in the calculation of exposures to persons who are in contact with patients who have received for therapeutic purposes. The effect of changing dose limits, contact patterns and using individually derived clearance rates may be readily modelled.

  6. How Medicaid agencies administer mental health services: results from a 50-state survey.

    Verdier, James; Barrett, Allison

    2008-10-01

    This brief report describes some notable variations in how state Medicaid agencies administer and fund Medicaid mental health services. Hour-long telephone interviews were conducted with all state and District of Columbia Medicaid directors or their designees. Responses indicated that Medicaid and mental health agencies were located within the same umbrella agency in 28 states, potentially facilitating collaboration. The mental health agency provided funding for some Medicaid mental health services in 32 states, and counties provided such funding in 22 states. Medicaid agencies generally delegated more authority to state mental health agencies in states where some Medicaid funding came from mental health sources and also in states where both agencies were in the same umbrella agency. The increasing role of Medicaid in funding state mental health services, combined with new federal limits on Medicaid financing of these services, underscores the importance of interagency collaboration and better alignment of Medicaid and mental health responsibilities.

    A number of investigators have demonstrated that when inorganic arsenic is administered to humans and experimental animals, methylarsonic acid (MAA) is formed in vivo. Low concentrations of MAA have been detected in human organs and urine. Few studies of the metabolism and elimination of MAA have been published. Following administration of a single oral dose of MAA to human subject, it was reported that MAA was rapidly metabolized to dimethylarsinic acid (DMAA) in vivo and excreted in urine. While the elimination of MAA has been investigated experimentally in animals, nothing is known of MAA metabolism and distribution in vivo. In the present study, the metabolism of MAA was investigated following its administration to hamsters. Arsenic species deposited in selected organs and blood, and the amounts and chemical species of arsenic excreted in urine and feces were determined.

    The present experiment tested whether the elasticity of demand for self-administered cocaine in rats is dose-dependent. Subjects lever pressed for three different doses of intravenous cocaine - 0.11, 0.33, and 1.0 mg/kg/infusion - on a demand procedure where the number of lever presses required per infusion increased within a session. The main finding was that demand for the 0.11 mg/kg dose was more elastic than it was for the two larger doses. There was no difference in demand elasticity between the 0.33 and 1.0 mg/kg doses. These results parallel findings previously reported in monkeys. The present study also demonstrated that a within-session procedure can be used to generate reliable demand curves.

    Full text of publication follows. Aims: the purpose of the study was to optimized 131-MIBG (or 131 I-MIBG) therapy in children and adults patients with neural crest tumors, by correlating the administered pro/KXg activity to whole-body dosimetry and hematologic toxicity. Materials and methods: from September 2003, to June 2012 twenty-four patients (9 children, 15 adults) (13 neuroblastoma, 9 pheochromocytoma/paraganglioma, 2 medullary thyroid carcinoma) treated with 131 I-MIBG were enrolled in the study. In each patient dosimetric estimation was carried out with MIRD method after patient therapy, using imaging acquisition or probe determination (from 1 to 168 hours). Hematological toxicity was evaluated according to WHO grade by weekly blood count for at least 6 weeks or until recovery. Whole Body Dose (WBD) was correlated with administered pro/KXg activity and bone marrow toxicity. Results: a total of forty-five dosimetric studies have been performed, 16/45 in children and 29/45 in adult patients. Administered activity ranged from 7.4 to 16.65 GBq, corresponding in children to 5-21 mCi/KXg (median 10 mCi/KXg) and in adults to 3-7 mCi/KXg. (median 5 mCi/KXg). In 4 patients (3 children, 1 adult) 2 weeks after 131 I-MING therapy autologous stem cell transplantations were performed. Grade II-III hematological toxicity was observed in all children and in 6/15 adult patient. Whole Body Dose ranged from 1 Gy to 3.6 Gy (median 1.7 Gy) in children, meanwhile it ranged between 0.55 and 1.87 Gy (median 0.96 Gy) in adults. In 5/16 children studies WBD was about 2 Gy and one child received a dose of 3.6 Gy (0.4 Gy/GBq), corresponding to an activity of 18 mCi/KXg. Conclusion: contrary to published data in children the pro/KXg activity is not a good predictor of WBD. In these cases WBD calculation can be affected by the presence of large tumor masses which overestimates the absorbed dose. In any case the administration of activity superior to 15 mCi/KXg is known to be associated

    A detailed fractionation of radioactivity in the milk of goats administered 14 C-aflatoxin B1 at low doses was performed. The milk collected in the first 24 h following dosing contained radioactivity equivalent to 0.45-1.1% of the dose given. The radioactivity in each sample was partitioned into 4 fractions: ether, protein, dichloromethane, and water-alcohol. Over 80% of the radioactivity was detected in the dichloromethane fraction, of which over 95% was attributable to aflatoxin M1. No aflatoxin B1 or other known aflatoxin metabolites were detected in any fraction. The results indicate that the major metabolite of aflatoxin B1 in goat milk is aflatoxin M1 and that other metabolites, including conjugates, are of minor significance

    A randomized triple blind intervention field/community trial was conducted to compare different outcome parameters like morbidity rate, mortality rate, conception rate, prophylactic/ therapeutic efficacy rate and cost benefit ratio in a dairy cluster of district Kasur and Okara where the community based animal health delivery system was being practiced. In a cluster of 30 villages, 15 villages were selected as interventional group comprising of 1101 dairy animals and rest of the 15 villages as non- interventional control (placebo) group comprising of 9513 dairy animals. In the non-interventional group of villages, vaccinations anthelmintic and mineral mixture administration as a package was not practiced by the community animal health workers(CAHWS). In the intervention villages group, the preventive package was administered at the rate ranging from 95 to 100 %. The result with respect to morbidity rate, morality rate, conception rate and cost- benefit ratio was significantly better (P< 0.05) in the interventional group as compared to the non-interventional group. In both the groups the ratio of cattle and buffaloes ranged between 1:2.72 and 1: 2.82. (author)

    To compare human chorionic gonadotropin (HCG)-administered natural cycle with spontaneous ovulatory cycle in patients undergoing frozen-thawed embryo transfer (FTET) in natural cycles. In this retrospective cohort study, we analyzed the clinical outcome of a total of 166 consecutive FTET cycles that were performed in either natural cycle controlled by HCG for ovulation triggering (HCG group, n=110) or natural cycle with spontaneous ovulation (control group, n=56) in 166 infertile patients between January 2009 and November 2013. There were no differences in patients' characteristics between the 2 groups. The numbers of oocytes retrieved, mature oocytes, fertilized oocytes, grade I or II embryos and frozen embryos in the previous in vitro fertilization (IVF) cycle in which embryos were frozen were comparable between the HCG and control groups. Significant differences were not also observed between the 2 groups in clinical pregnancy rate (CPR), embryo implantation rate, miscarriage rate, live birth rate and multiple CPR. However, the number of hospital visits for follicular monitoring was significantly fewer in the HCG group than in the control group ( P cycle reduces the number of hospital visits for follicular monitoring without any detrimental effect on FTET outcome when compared with spontaneous ovulatory cycles in infertile patients undergoing FTET in natural ovulatory cycles.

  15. Regulatory analysis on criteria for the release of patients administered radioactive material

    The Nuclear Regulatory Commission (NRC) has received two petitions to amend its regulations in 10 CFR Parts 20 and 35 as they apply to doses received by members of the public exposed to patients released from a hospital after they have been administered radioactive material. While the two petitions are not identical they both request that the NRC establish a dose limit of 5 millisieverts (0.5 rem) per year for individuals exposed to patients who have been administered radioactive materials. This Regulatory Analysis evaluates three alternatives. Alternative 1 is for the NRC to amend its patient release criteria in 10 CFR 35.75 to use the more stringent dose limit of 1 millisievert per year in 10 CFR 20.1301(a) for its patient release criteria. Alternative 2 is for the NRC to continue using the existing patient release criteria in 10 CFR 35.75 of 1,110 megabecquerels of activity or a dose rate at one meter from the patient of 0.05 millisievert per hour. Alternative 3 is for the NRC to amend the patient release criteria in 10 CFR 35.75 to specify a dose limit of 5 millisieverts for patient release. The evaluation indicates that Alternative 1 would cause a prohibitively large increase in the national health care cost from retaining patients in a hospital longer and would cause significant personal and psychological costs to patients and their families. The choice of Alternatives 2 or 3 would affect only thyroid cancer patients treated with iodine-131. For those patients, Alternative 3 would result in less hospitalization than Alternative 2. Alternative 3 has a potential decrease in national health care cost of $30,000,000 per year but would increase the potential collective dose from released therapy patients by about 2,700 person-rem per year, mainly to family members

    To investigate the effects of oral administration of activated charcoal (AC) and urine alkalinization via oral administration of sodium bicarbonate on the pharmacokinetics of orally administered carprofen in dogs. 6 neutered male Beagles. Each dog underwent 3 experiments (6-week interval between experiments). The dogs received a single dose of carprofen (16 mg/kg) orally at the beginning of each experiment; after 30 minutes, sodium bicarbonate (40 mg/kg, PO), AC solution (2.5 g/kg, PO), or no other treatments were administered. Plasma concentrations of unchanged carprofen were determined via high-performance liquid chromatography at intervals until 48 hours after carprofen administration. Data were analyzed by use of a Student paired t test or Wilcoxon matched-pairs rank test. Compared with the control treatment, administration of AC decreased plasma carprofen concentrations (mean +/- SD maximum concentration was 85.9 +/- 11.9 mg/L and 58.1 +/- 17.6 mg/L, and area under the time-concentration curve was 960 +/- 233 mg/L x h and 373 +/- 133 mg/L x h after control and AC treatment, respectively). The elimination half-life remained constant. Administration of sodium bicarbonate had no effect on plasma drug concentrations. After oral administration of carprofen in dogs, administration of AC effectively decreased maximum plasma carprofen concentration, compared with the control treatment, probably by decreasing carprofen absorption. Results suggest that AC can be used to reduce systemic carprofen absorption in dogs receiving an overdose of carprofen. Oral administration of 1 dose of sodium bicarbonate had no apparent impact on carprofen kinetics in dogs.

    Good personal hygiene (PH) behavior is recommended to prevent contagious diseases, and members of military forces may be at high risk for contracting contagious diseases. The aim of this study was to develop and test a new questionnaire on PH for soldiers. Participants were all male and from different military settings throughout Iran. Using a five-stage guideline, a panel of experts in the Persian language (Farsi) developed a 21-item self-administered questionnaire. Face and content validity of the first-draft items were assessed. The questionnaire was then translated and subsequently back-translated into English, and both the Farsi and English versions were tested in pilot studies. The consistency and stability of the questionnaire were tested using Cronbach's alpha and the test-retest strategy. The final scale was administered to a sample of 502 military personnel. Explanatory and confirmatory factor analyses evaluated the structure of the scale. Both the convergent and discriminative validity of the scale were also determined. Cronbach's alpha coefficients were >0.85. Principal component analysis demonstrated a uni-dimensional structure that explained 59 % of the variance in PH behaviors. Confirmatory factor analysis indicated a good fit (goodness-of-fit index = 0.902; comparative fitness index = 0.923; root mean square error of approximation = 0.0085). The results show that this new PH scale has solid psychometric properties for testing PH behaviors among an Iranian sample of military personnel. We conclude that this scale can be a useful tool for assessing PH behaviors in military personnel. Further research is needed to determine the scale's value in other countries and cultures.

    Cyclooxygenase-2 (COX-2) inhibitors reduce prostaglandin synthesis and disrupt essential reproductive processes. Ultrasound studies in women demonstrated that oral COX-2 inhibitors can delay or prevent follicle collapse associated with ovulation. The goal of this study was to determine if oral administration of a COX-2 inhibitor can inhibit reproductive function with sufficient efficacy to prevent pregnancy in primates. The COX-2 inhibitor meloxicam (or vehicle) was administered orally to proven fertile female cynomolgus macaques using one emergency contraceptive model and three monthly contraceptive models. In the emergency contraceptive model, females were bred with a proven fertile male once 2±1 days before ovulation, returned to the females' home cage, and then received 5 days of meloxicam treatment. In the monthly contraceptive models, females were co-caged for breeding with a proven fertile male for a total of 5 days beginning 2±1 days before ovulation. Animals received meloxicam treatment (1) cycle days 5-22, or (2) every day, or (3) each day of the 5-day breeding period. Female were then assessed for pregnancy. The pregnancy rate with meloxicam administration using the emergency contraception model was 6.5%, significantly lower than the pregnancy rate of 33.3% when vehicle without meloxicam was administered. Pregnancy rates with the three monthly contraceptive models (75%-100%) were not consistent with preventing pregnancy. Oral COX-2 inhibitor administration can prevent pregnancy after a single instance of breeding in primates. While meloxicam may be ineffective for regular contraception, pharmacological inhibition of COX-2 may be an effective method of emergency contraception for women. COX-2 inhibitors can interfere with ovulation, but the contraceptive efficacy of drugs of this class has not been directly tested. This study, conducted in nonhuman primates, is the first to suggest that a COX-2 inhibitor may be effective as an emergency contraceptive.

    Full Text Available The integrity and function of the gut is impaired in HIV-infected individuals, and gut pathogenesis may play a role in several HIV-associated disorders. Methamphetamine is a popular illicit drug abused by HIV-infected individuals. However, the effect of methamphetamine on the gut and its potential to exacerbate HIV-associated gut pathology is not known. To shed light on this scenario, we evaluated colon barrier pathology in a rat model of the human comorbid condition. Intestinal barrier integrity and permeability were assessed in drug-naïve Fischer 344 HIV-1 transgenic (Tg and non-Tg rats, and in Tg and non-Tg rats instrumented with jugular cannulae trained to self-administer methamphetamine or serving as saline-yoked controls. Intestinal permeability was determined by measuring the urine content of orally gavaged sugars. Intestinal barrier integrity was evaluated by immunoblotting or immunofluorescence of colon claudin-1 and zonula occludens-1 (ZO-1, two major tight junction proteins that regulate gut epithelial paracellular permeability. Both non-Tg and Tg rats self-administered moderate amounts of methamphetamine. These amounts were sufficient to increase colon permeability, reduce protein level of claudin-1, and reduce claudin-1 and ZO-1 immunofluorescence in Tg rats relative to non-Tg rats. Methamphetamine decreased tight junction immunofluorescence in non-Tg rats, with a similar, but non-significant trend observed in Tg rats. However, the effect of methamphetamine on tight junction proteins was subthreshold to gut leakiness. These findings reveal that both HIV-1 proteins and methamphetamine alter colon barrier integrity, and indicate that the gut may be a pathogenic site for these insults.

    Full Text Available Controlled human malaria infection (CHMI studies have become a routine tool to evaluate efficacy of candidate anti-malarial drugs and vaccines. To date, CHMI trials have mostly been conducted using the bite of infected mosquitoes, restricting the number of trial sites that can perform CHMI studies. Aseptic, cryopreserved P. falciparum sporozoites (PfSPZ Challenge provide a potentially more accurate, reproducible and practical alternative, allowing a known number of sporozoites to be administered simply by injection.We sought to assess the infectivity of PfSPZ Challenge administered in different dosing regimens to malaria-naive healthy adults (n = 18. Six participants received 2,500 sporozoites intradermally (ID, six received 2,500 sporozoites intramuscularly (IM and six received 25,000 sporozoites IM.Five out of six participants receiving 2,500 sporozoites ID, 3/6 participants receiving 2,500 sporozoites IM and 6/6 participants receiving 25,000 sporozoites IM were successfully infected. The median time to diagnosis was 13.2, 17.8 and 12.7 days for 2,500 sporozoites ID, 2,500 sporozoites IM and 25,000 sporozoites IM respectively (Kaplan Meier method; p = 0.024 log rank test.2,500 sporozoites ID and 25,000 sporozoites IM have similar infectivities. Given the dose response in infectivity seen with IM administration, further work should evaluate increasing doses of PfSPZ Challenge IM to identify a dosing regimen that reliably infects 100% of participants.ClinicalTrials.gov NCT01465048.

    The aim of this study was to assess the direct healthcare costs of outpatient parenteral antimicrobial therapy (OPAT) administered by Hospital at Home (HaH) units in Spain. An observational, multicentre, economic evaluation of retrospective cohorts was conducted. Patients were treated at home by the HaH units of three Spanish hospitals between January 2012 and December 2013. From the cost accounting of HaH OPAT (staff, pharmacy, transportation, diagnostic tests and structural), the cost of each outpatient course was obtained following a top-down strategy based on the use of resources. Costs associated with inpatient stay, if any, were estimated based on length of stay and ICD-9-CM diagnosis. There were 1324 HaH episodes in 1190 patients (median age 70 years). The median (interquartile range) stay at home was 10 days (7-15 days). Of the OPAT episodes, 91.5% resulted in cure or improvement on completion of intravenous therapy. The mean total cost of each infectious episode was €6707 [95% confidence interval (CI) €6189-7406]. The mean cost per OPAT episode was €1356 (95% CI €1247-1560), mainly distributed between healthcare staff costs (46%) and pharmacy costs (39%). The mean cost of inpatient hospitalisation of an infectious episode was €4357 (95% CI €3947-4977). The cost per day of inpatient hospitalisation was €519, whilst the cost per day of OPAT was €98, meaning a saving of 81%. This study shows that OPAT administered by HaH units resulted in lower costs compared with inpatient care in Spain. Copyright © 2017 Elsevier B.V. and International Society of Chemotherapy.

    Normal adult inbred SWR/J mice were used to investigate the teratogenic and other possible toxic effects of various dose levels of sildenafil citrate (Viagra) on fetuses. Multiple dose levels of 6.5, 13.0, 19.5, 26.0, 32.5 or 40.0 mg of sildenafil citrate/kg body weight (which correspond to the multiples of 1, 2, 3, 4, 5 or 6 of human 50 mg Viagra, respectively) were orally administered into pregnant mice on days 7-9, 10-12 or 13-15 of gestation. On day 17 of pregnancy, all fetuses were removed and examined for toxic phenomena (embryo-fetal toxicity) and for external, internal and skeletal malformations. A total of 285 pregnant mice were used in the present study. None of the dams treated with sildenafil citrate at any of the oral dose levels used in the present study died during the experimental period and all dams treated with the drug failed to reveal overt signs of maternal toxicity. Moreover, the results of the present study clearly demonstrate that none of the multiple oral dose levels of the drug at any time interval used has induced any external, internal or skeletal malformations in the fetuses obtained from treated females. However, the dose level of 40 mg/kg body weight of sildenafil citrate has a growth suppressing effect on alive fetuses when it was administered at all the time intervals used in the present study. Furthermore, the dose levels 26.0, 32.5 and 40 mg/kg of the drug have embryo-fetal toxicity when the drug is applied on days 13-15 of gestation. The possible mechanisms involved in the embryo-fetal toxicity and fetal growth suppressing effects of sildenafil citrate were discussed. The results of this study have important implications for the widespread use of this drug.

    We reported previously that priming of the respiratory tract with immunobiotic Lactobacillus prior to virus challenge protects mice against subsequent lethal infection with pneumonia virus of mice (PVM). We present here the results of gene microarray which document differential expression of proinflammatory mediators in response to PVM infection alone and those suppressed in response to Lactobacillus plantarum. We also demonstrate for the first time that intranasal inoculation with live or heat-inactivated L. plantarum or Lactobacillus reuteri promotes full survival from PVM infection when administered within 24h after virus challenge. Survival in response to L. plantarum administered after virus challenge is associated with suppression of proinflammatory cytokines, limited virus recovery, and diminished neutrophil recruitment to lung tissue and airways. Utilizing this post-virus challenge protocol, we found that protective responses elicited by L. plantarum at the respiratory tract were distinct from those at the gastrointestinal mucosa, as mice devoid of the anti-inflammatory cytokine, interleukin (IL)-10, exhibit survival and inflammatory responses that are indistinguishable from those of their wild-type counterparts. Finally, although L. plantarum interacts specifically with pattern recognition receptors TLR2 and NOD2, the respective gene-deleted mice were fully protected against lethal PVM infection by L. plantarum, as are mice devoid of type I interferon receptors. Taken together, L. plantarum is a versatile and flexible agent that is capable of averting the lethal sequelae of severe respiratory infection both prior to and post-virus challenge via complex and potentially redundant mechanisms.

    Elastomeric pumps can be useful for the administration of antibiotics in the outpatient setting. To determine amoxicillin degradation in elastomeric pumps, as well as the effectiveness of amoxicillin treatment administered by elastomeric pumps. Antibiotic degradation was measured in elastomeric pumps filled with 6 g of amoxicillin in 240 mL of NaCl 0.9% by drawing samples at 12 h intervals when stored in the fridge for 48 h and when worn around the waist for 24 h. Subsequently nine patients were treated with continuous infusions of 8 or 12 g of amoxicillin per day. Plasma amoxicillin concentrations were measured on each visit to the outpatient parenteral antibiotic therapy unit. Clinical outcome was verified 3 months after the end of treatment. Amoxicillin degradation in elastomeric pumps reached 10% after 48 h in the fridge and an additional 30% when worn around the waist for 24 h. Mean plasma drug concentrations achieved with 12 g of amoxicillin per day were 18.5 mg/L (95% CI 13.5-23.5), which is largely above the MIC of amoxicillin-susceptible bacteria. Nine patients treated for various complicated infections were cured and had no unexpected adverse effects. Adequate plasma drug concentrations and favourable clinical outcomes suggest that amoxicillin can be administered by continuous infusion using elastomeric pumps. This treatment modality does not fulfil formal requirements regarding pharmaceutical stability, but the resulting safety impact in patients is probably limited. Therapeutic drug monitoring and a close clinical follow-up are recommended if this route of administration is chosen. © The Author 2017.

    A continuous subcutaneous infusion (CSCI) delivered via syringe pump is a method of drug administration used to maintain symptom control when a patient is no longer able to tolerate oral medication. Several classes of drugs, such as opioids, antiemetics, anticholinergics, antipsychotics and benzodiazepines are routinely administered by CSCI alone or in combinations. Previous studies attempting to identify the most-common CSCI combinations are now several years old and no longer reflect current clinical practice. The aim of this work was to review current clinical practice and identify CSCI drug combinations requiring analysis for chemical compatibility and stability. UK pharmacy professionals involved in the delivery of care to palliative patients in hospitals and hospices were invited to enter CSCI combinations comprised of two or more drugs onto an electronic database over a 12-month period. In addition, a separate Delphi study with a panel of 15 expert healthcare professionals was completed to identify a maximum of five combinations of drugs used to treat more complex, but less commonly encountered symptoms unlikely to be identified by the national survey. A total of 57 individuals representing 33 separate palliative care services entered 1,945 drug combinations suitable for analysis, with 278 discrete combinations identified. The top 40 drug combinations represented nearly two-thirds of combinations recorded. A total of 23 different drugs were administered in combination and the median number of drugs in a combination was three. The Delphi study identified five combinations for the relief of complex or refractory symptoms. This study represents the first step towards developing authoritative national guidance on the administration of drugs by CSCI. Further work will ensure healthcare practitioners have the knowledge and confidence that a prescribed combination will be both safe and efficacious.

    Increased doses of detomidine are required to produce sedation in horses after maximal exercise compared to calm or resting horses. To determine if the pharmacokinetics of detomidine in Thoroughbred horses are different when the drug is given during recuperation from a brief period of maximal exercise compared to administration at rest. Six Thoroughbred horses were preconditioned by exercising them on a treadmill. Each horse ran a simulated race at a treadmill speed that caused it to exercise at 120% of its maximal oxygen consumption. One minute after the end of exercise, horses were treated with detomidine. Each horse was treated with the same dose of detomidine on a second occasion a minimum of 14 days later while standing in a stocks. Samples of heparinised blood were obtained at various time points on both occasions. Plasma detomidine concentrations were determined by liquid chromatography-mass spectrometry. The plasma concentration vs. time data were analysed by nonlinear regression analysis. Median back-extrapolated time zero plasma concentration was significantly lower and median plasma half-life and median mean residence time were significantly longer when detomidine was administered after exercise compared to administration at rest. Median volume of distribution was significantly higher after exercise but median plasma clearance was not different between the 2 administrations. Detomidine i.v. is more widely distributed when administered to horses immediately after exercise compared to administration at rest resulting in lower peak plasma concentrations and a slower rate of elimination. The dose requirement to produce an equivalent effect may be higher in horses after exercise than in resting horses and less frequent subsequent doses may be required to produce a sustained effect.

    Many clinical investigations use generic and/or specific questionnaires to obtain information about participants and patients. There is disagreement about whether the administration method can affect the results. The aim here was to determine whether, among patients with intermittent claudication (IC), there are differences in the Walking Impairment Questionnaire (WIQ) and European Quality of Life-5 Dimension (EQ-5D) scores with regard to: 1) the questionnaire administration method (self-administration versus face-to-face interview); and 2) the type of interviewer (vascular surgeon, VS, versus general practitioner, GP). Cross-sectional observational multicenter epidemiological study carried out within the Spanish National Health Service. 1,641 evaluable patients with IC firstly completed the WIQ and EQ-5D questionnaires and then were interviewed by their doctor on the same day. Pearson correlations and Chi-square tests were used. There was a strong correlation (r > 0.800; P questionnaires, and between the VS and GP groups. Likewise, there was a high level of concordance (P > 0.05) between the different dimensions of the WIQ-distance and EQ-5D (self-administration versus face-to-face) in the VS and GP groups. There was no difference between the different methods of administering the WIQ and EQ-5D questionnaires, among the patients with IC. Similarly, the two types of interviewers (VS or GP) were equally valid. Therefore, it seems unnecessary to expend effort to administer these questionnaires by interview, in studies on IC.

    Full Text Available The current study was designed to probe pathological effects of colistin in growing broilers. One hundred twenty day-old broiler chicks were divided into six equal groups A-F. These birds were injected colistin sulphate, 0, 5, 10, 20, 40 and 80 mg/kg BW respectively through intramuscular route. The different serum-biochemical parameters including total protein, albumen, globulin, ALT, AST, LDH, GGT, creatinine and BUN were determined at day 21 and 42 of experiment. The hematological parameters including RBC, WBC, PCV and Hb were determined twice. The serum total protein values were significantly higher in group E as compared with control group. At day 42 groups, C-E had significantly lower albumen values as compared to group A. The similar pattern was observed in globulin values. The creatinine & urea was also found significantly higher in group D and E at day 21 of experiment, while at day 42 all the groups having significantly higher urea level in comparison with group A indicating nephrotoxic effect of colistin. The serum enzymes including ALT and AST were significantly higher in group D & E as compared with group A, which is an indication of liver damage. The LDH and GGT values showed significantly increasing trend in experimental groups compared with control. The erythrocytes and leucocytes count were significantly higher in control and low dose groups as compared with higher colistin dose groups. It is concluded that lavish parenteral administration of colistin resulted in increased levels of hepato-renal serum indicators and lower values of hematological parameters.

  14. Geometric group theory

    CERN Document Server

    Druţu, Cornelia

    2018-01-01

    The key idea in geometric group theory is to study infinite groups by endowing them with a metric and treating them as geometric spaces. This applies to many groups naturally appearing in topology, geometry, and algebra, such as fundamental groups of manifolds, groups of matrices with integer coefficients, etc. The primary focus of this book is to cover the foundations of geometric group theory, including coarse topology, ultralimits and asymptotic cones, hyperbolic groups, isoperimetric inequalities, growth of groups, amenability, Kazhdan's Property (T) and the Haagerup property, as well as their characterizations in terms of group actions on median spaces and spaces with walls. The book contains proofs of several fundamental results of geometric group theory, such as Gromov's theorem on groups of polynomial growth, Tits's alternative, Stallings's theorem on ends of groups, Dunwoody's accessibility theorem, the Mostow Rigidity Theorem, and quasiisometric rigidity theorems of Tukia and Schwartz. This is the f...

    Lymphangiectasia is one of the causes of protein-losing enteropathy in dogs and characteristic ultrasonographic small intestinal lesions have been previously described. The purpose of this study was to determine whether corn oil administered orally (COAO) would result in increased conspicuity of these characteristic small intestinal ultrasonographic lesions in dogs with lymphangiectasia. Affected dogs were included if they underwent corn oil administered orally and had a surgical full-thickness intestinal biopsy diagnosis of lymphangiectasia. Control dogs had normal clinical examination and standard laboratory test findings. Ultrasound images of duodenum, jejunum, and ileum were obtained prior to and 30, 60, 90, and 120 min after corn oil administered orally for all dogs. Parameters recorded for each ultrasound study were intestinal wall thickness, mucosal echogenicity, and presence or absence of hyperechoic mucosal striations (HMS) and a parallel hyperechoic mucosal line (PHML). Nine affected and five controls dogs were included in the study. Seven of the nine dogs with lymphangiectasia had hyperechoic mucosal striations prior to corn oil administered orally. Jejunal hyperechoic mucosal striations were significantly associated with lymphangiectasia at multiple time points (P dogs with lymphangiectasia 60 or 90 min after corn oil administered orally. Increased mucosal echogenicity was observed in all dogs at multiple time points after corn oil administered orally. A parallel hyperechoic mucosal line was present in the jejunum in 4/5 healthy and 6/9 dogs with lymphangiectasia at one or more time points after corn oil administered orally. Findings indicated that corn oil administered orally improves conspicuity of characteristic ultrasonographic lesions in dogs with lymphangiectasia, however some of these lesions may also be present in healthy dogs that recently received a fatty meal. © 2013 Veterinary Radiology & Ultrasound.

  1. Group purchasing: an overview.

    Science.gov (United States)

    Wetrich, J G

    1987-07-01

    The various types and operational methods of purchasing groups are described, and evaluation of groups is discussed. Since group purchasing is increasing in popularity as a method of controlling drug costs, community and hospital pharmacy managers may need to evaluate various groups to determine the appropriateness of their services. Groups are categorized as independent, system based, or alliance or association based. Instead of "purchasing," some groups develop contracts for hospitals, which then purchase directly from the vendor. Aside from this basic difference between groups that purchase and groups that contract, comparisons among groups are difficult because of the wide variation in sizes and services. Competition developing from diversification among groups has led to "super groups," formed from local and regional groups. In evaluating groups, advantages and disadvantages germane to accomplishing the member's objectives must be considered. To ensure a group's success, members must be committed and support the group's philosophies; hospital pharmacists must help to establish a strong formulary system. To select vendors, groups should develop formal qualification and selection criteria and should not base a decision solely on price. The method of solicitation (bidding or negotiating), as well as the role of the prime vendor, should be studied. Legal implications of group purchasing, especially in the areas of administrative fees and drug diversion, must also be considered. The most advantageous group for each organization will include members with common missions and will be able to implement strategies for future success.

In this paper, we report the development and preliminary validation of a new computer-administered and -scored health literacy measure addressing these limitations. Items in the measure reflect a wide range of content related to health promotion and maintenance as well as care for diseases. The development process has focused on creating a measure that will be useful in both Spanish and English, while not requiring substantial time for clinician training and individual administration and scoring. The items incorporate several formats, including questions based on brief videos, which allow for the assessment of listening comprehension and the skills related to obtaining information on the Internet. In this paper, we report the interim analyses detailing the initial development and pilot testing of the items (phase 1 of the project in groups of Spanish and English speakers. We then describe phase 2, which included a second round of testing of the items, in new groups of Spanish and English speakers, and evaluation of the new measure's reliability and validity in relation to other measures.

    To compare the data quality, logistics, and cost of a self-administered sexual behavior questionnaire administered either using a computer-assisted survey instrument (CASI) or by paper and pencil in a primary care clinic. A self-administered sexual behavior questionnaire was administered to 16-29 year olds attending general practice. Questionnaires were administered by either paper and pencil (paper) or CASI. A personal digital assistant was used to self-administer the CASI. A total of 4,491 people completed the questionnaire, with 46.9% responses via CASI and 53.2% by paper. Completion of questions was greater for CASI than for paper for sexual behavior questions: number of sexual partners [odds ratio (OR), 6.85; 95% confidence interval (CI): 3.32, 14.11] and ever having had sex with a person of the same gender (OR, 2.89; 95% CI: 1.52, 5.49). The median number of questions answered was higher for CASI than for paper (17.6 vs. 17.2; P questionnaire compared with $11.83 for paper. Electronic devices using CASI are a tool that can increase participants' questionnaire responses and deliver more complete data for a sexual behavior questionnaire in primary care clinics.

  5. Ordered groups and infinite permutation groups

    CERN Document Server

    1996-01-01

    The subjects of ordered groups and of infinite permutation groups have long en­ joyed a symbiotic relationship. Although the two subjects come from very different sources, they have in certain ways come together, and each has derived considerable benefit from the other. My own personal contact with this interaction began in 1961. I had done Ph. D. work on sequence convergence in totally ordered groups under the direction of Paul Conrad. In the process, I had encountered "pseudo-convergent" sequences in an ordered group G, which are like Cauchy sequences, except that the differences be­ tween terms of large index approach not 0 but a convex subgroup G of G. If G is normal, then such sequences are conveniently described as Cauchy sequences in the quotient ordered group GIG. If G is not normal, of course GIG has no group structure, though it is still a totally ordered set. The best that can be said is that the elements of G permute GIG in an order-preserving fashion. In independent investigations around that t...

    Full Text Available The aim of our study has been to assess the comparative use of the two NSAIDs, dexketoprofen and ketoprofen, for postoperative analgesia after laparoscopic cholecystectomy mainly following: the quality of the analgesia, the incidence of potential adverse effects (for example, postoperative nausea and vomiting and the rescue analgesics consumption (tramadol. This prospective, randomized, double-blind study included 90 patients undergoing laparoscopic cholecystectomy under general anaesthesia. Patients were randomly assigned into 2 groups: group D (n = 45 - patients that have received dexketoprofen 50 mg in dilution with10 ml saline solution iv., 30 minutes before the induction and group K (n = 45 - patients that have received ketoprofen 100 mg in dilution with 10 ml saline solution iv., 30 minutes before the induction (preemptive analgesia. Surgical interventions were conducted under general anaesthesia, with identical protocol for the two groups of study. Post-surgery analgesic regime consisting in 4 g of paracetamol administered for example in the first 24 hours, was started immediately after surgery. Boluses of tramadol of 100 mg (until 400 mg /daily have been used as rescue analgesia. The main objectives of our study have been: post-surgery analgesia (VAS at mobilization, 0-100 mm at 0, 2, 6, 12 and 24 hours after the surgery,the consumption of tramadol, incidence of PONV and the length of hospitalization period (LOS. Secondary objectives of the study have been: the incidence of gastrointestinal symptoms and the incidence of postsurgery blood losses. In the two study groups there have not been any differences concerning demographic data, post-surgery gastro-intestinal symptoms, postsurgery loss of blood and the hospitalization period. VAS was significantly lower in group D vs. K, at 0 and 6 hours after the surgery (p <0,05.

    The CANDU Owners Group (COG) was formed in 1984 by the Canadian CANDU owning utilities and Atomic Energy of Canada limited (AECL). Participation was subsequently extended to all CANDU owners world-wide. The mandate of the COG organization is to provide a framework for co-operation, mutual assistance and exchange of information for the successful support, development, operation, maintenance and economics of CANDU nuclear electric generating stations. To meet these objectives COG established co-operative programs in two areas: 1. Station Support. 2. Research and Development. In addition, joint projects are administered by COG on a case by case basis where CANDU owners can benefit from sharing of costs

    To investigate the effect of the self-administered superficial local hot and cold applications on pain, and the functional status and the quality of life in primary knee osteoarthritis patients. Superficial local hot and cold application is used as a nonpharmacological method for the treatment of knee osteoarthritis. However, various guidelines for the management of knee osteoarthritis have conflicting recommendation for hot and cold therapy. A randomised clinical trial design. The sample consisted of patients (n = 96) who were diagnosed with primary knee osteoarthritis. During the application stage, patients were designated to the hot and cold application groups and administered hot and cold application twice a day for 3 weeks together with standard osteoarthritis treatment. The control group only used standard osteoarthritis treatment. The data were collected with a Descriptive Information Form, a Pain Scale, the WOMAC Osteoarthritis Index, the Nottingham Health Profile (NHP) and a Patient Satisfaction Evaluation Form. Outcome measures included pain intensity, functional status and quality of life. We found decreased primary measurement pain scores and improved functional status scores and quality of life scores after the application programme compared to the pre-application stage in both the hot and cold application groups. Once the application was completed, the pain scores, functional status scores and quality-of-life scores on the second measurements were found to be still statistically lower than the pre-application scores but higher than the first measurement ([p  .05). It was found that both hot and cold application resulted in a mild improvement in pain, functional status and quality of life, but this improvement was not sufficient to create a significant difference between the groups. This study contributes to the literature on hot and cold application methods as self-management strategies for patients with knee osteoarthritis. © 2017 John Wiley

    Avian colibacillosis is responsible for economic losses to poultry producers worldwide. To combat this, we aimed to develop an effective oral vaccine for chicken against O78 avian pathogenic Escherichia coli (APEC) infection through a Lactobacillus delivery system. Eight Lactobacillus strains isolated from the intestines of broiler chickens were evaluated based on their in vitro adherence ability to assess their potential as a delivery vector. Fimbrial subunit A (FimA) and outer-membrane protein C (OmpC) of APEC with and without fusion to dendritic cell-targeting peptide (DCpep) and microfold cell-targeting peptide (Co1) were displayed on the surface of Lactobacillus saerimneri M-11 and yielded vaccine groups (pPG-ompC-fimA/M-11 and pPG-ompC-fimA-Co1-DCpep/M-11, respectively). The colonization of the recombinant strains in vivo was assessed and the immunogenicity and protective efficacy of orally administered recombinant strains in chickens were evaluated. The colonization of the recombinant strains in vivo revealed no significant differences between the recombinant and wild-type strains. Chickens orally administered with vaccine groups showed significantly higher levels of OmpC/FimA-specific IgG in serum and mucosal IgA in cecum lavage, nasal lavage and stool compared to the pPG/M-11 group. After challenge with APEC CVCC1553, better protective efficacy was observed in chickens orally immunized with pPG-ompC-fimA/M-11 and pPG-ompC-fimA-Co1-DCpep/M-11, but no significant differences were observed between the two groups. Recombinant chicken-borne L. saerimneri M-11 showed good immunogenicity in chickens, suggesting that it may be a promising vaccine candidate against APEC infections. However, the activity of mammalian DCpep and Co1 was not significant in chickens.

  10. Gquest: modeling patient questionnaires and administering them through a mobile platform application.

    2014-11-01

    The use of surveys is becoming popular in the health care industry for acquiring information useful to the accomplishment of several studies. Besides their exploitation on a large scale for conducting epidemiological studies, surveys are being increasingly carried out on a narrower perspective through the administration of questionnaires aimed at assessing the quality of life perceived by patients or their clinical status during mid- or long-term treatments. This is useful for managing resources or optimizing and individualizing treatments. This paper describes Gquest, a platform for modeling, generating and administering questionnaires through mobile devices such as smartphones or tablets. Gquest was motivated by the need of administering questionnaires during home treatments, albeit its applicability is rather general. The main requirement was to have a very simple, clean and easy to use platform able to support (a) physicians in the design and delivery of questionnaires and (b) outpatients in sending self-recorded outcomes to the clinical staff. Gquest has two basic components. The first one is a model devised for representing questionnaires which is extremely flexible. It allows the generation of questions and answers of different types, supports adaptivity in the dialog with the user and enforces simple consistency rules for checking his input. The second component is an application able to run instances of those questionnaires. It downloads questionnaires over the air in terms of XML files from a server and stores them locally into the mobile repository. Questionnaires become then available to the user, who in our case is a patient or one of his relatives. The user can select which one to fill-in, according to his needs and/or the specific treatment protocol. The selected questionnaire may be filled-in all at once or be completed in subsequent steps over time since any input provided is persisted on a local database. Finally, when a questionnaire is closed

    Purpose: Recent studies show promise that administering gold nanoparticles (GNP) to tumor cells during brachytherapy could significantly enhance radiation damage to the tumor. A new strategy proposed for sustained administration of the GNP in prostate tumors is to load them into routinely used brachytherapy spacers for customizable in situ release after implantation. This in silico study investigated the intratumor biodistribution and corresponding dose enhancement over time due to GNP released from such GNP-loaded brachytherapy spacers (GBS). Method and Materials: An experimentally determined intratumoral diffusion coefficient (D) for 10-nm nanoparticles was used to estimate D for other sizes by using the Stokes-Einstein equation. GNP concentration profiles, obtained using D, were then used to calculate the corresponding dose enhancement factor (DEF) for each tumor voxel, using dose painting-by-numbers approach, for times relevant to the considered brachytherapy sources' lifetimes. The investigation was carried out as a function of GNP size for the clinically applicable low-dose-rate brachytherapy sources iodine-125 (I-125), palladium-103 (Pd-103), and cesium-131 (Cs-131). Results: Results showed that dose enhancement to tumor voxels and subvolumes during brachytherapy can be customized by varying the size of GNP released or eluted from the GBS. For example, using a concentration of 7 mg/g GNP, significant DEF (>20%) could be achieved 5 mm from a GBS after 5, 12, 25, 46, 72, 120, and 195 days, respectively, for GNP sizes of 2, 5, 10, 20, 30, and 50 nm and for 80 nm when treating with I-125. Conclusions: Analyses showed that using Cs-131 provides the highest dose enhancement to tumor voxels. However, given its relatively longer half-life, I-125 presents the most flexibility for customizing the dose enhancement as a function of GNP size. These findings provide a useful reference for further work toward development of potential new brachytherapy application

    Arthritis afflicts approximately 43 million Americans or approximately 16.6% of the US population. The two most common and best known types of arthritis are osteoarthritis (OA) and rheumatoid arthritis (RA). A significant amount of scientific research has been done in attempts to explain what initiates forms of arthritis, how it is promoted and perpetuated and how to effectively intervene in the disease process and promote cartilage remodeling. Current pharmacological strategies mainly address immune suppression and antiinflammatory mechanisms and have had limited success. Recent research provides evidence that alterations in the three-dimensional configuration of glycoproteins are responsible for the recognition/response signaling that catalyzes T-cell attack. Oral administration of autoantigens has been shown to suppress a variety of experimentally induced autoimmune pathologies, including antigen-induced RA. The interaction between gut-associated lymphoid tissue in the duodenum and epitopes of orally administered undenatured type II collagen facilitates oral tolerance to the antigen and stems systemic T-cell attack on joint cartilage. Previous studies have shown that small doses of orally administered undenatured type II chicken collagen effectively deactivate killer T-cell attack. A novel glycosylated undenatured type II collagen material (UC-II) was developed to preserve biological activity. The presence of active epitopes in the UC-II collagen is confirmed by an enzyme-linked immunosorbent assay test and distinguishes this form from hydrolyzed or denatured collagen. Oral intake of small amounts of glycosylated UC-II presents active epitopes, with the correct three-dimensional structures, to Peyer's patches, which influences the signaling required for the development of immune tolerance. UC-II has demonstrated the ability to induce tolerance, effectively reducing joint pain and swelling in RA subjects. A pilot study was conducted for 42 days to evaluate the

    A small amount of food is commonly used to aid administration of medicines to children to improve palatability and/or swallowability. However the impact of this co-administered food on the absorption and subsequent pharmacokinetic profile of the drug is unknown. Existing information on food effects is limited to standard protocols used to evaluate the impact of a high fat meal in an adult population using the adult medication. In the absence of a substantial body of data, there are no specific guidelines available during development of paediatric products relating to low volumes of potentially low calorie food. This paper brings together expertise to consider how the impact of co-administered food can be risk assessed during the development of a paediatric medicine. Two case studies were used to facilitate discussions and seek out commonalities in risk assessing paediatric products; these case studies used model drugs that differed in their solubility, a poorly soluble drug that demonstrated a positive food effect in adults and a highly soluble drug where a negative food effect was observed. For poorly soluble drugs risk assessments are centred upon understanding the impact of food on the in vivo solubility of the drug which requires knowledge of the composition of the food and the volumes present within the paediatric gastrointestinal tract. Further work is required to develop age appropriate in vitro and in silico models that are representative of paediatric populations. For soluble drugs it is more important to understand the mechanisms that may lead to a food effect, this may include interactions with transporters or the impact of the food composition on gastro-intestinal transit or even altered gastric motility. In silico models have the most promise for highly soluble drug products although it is essential that these models reflect the relevant mechanisms involved in potential food effects. The development of appropriate in vitro and in silico tools is

A new strategy proposed for sustained administration of the GNP in prostate tumors is to load them into routinely used brachytherapy spacers for customizable in situ release after implantation. This in silico study investigated the intratumor biodistribution and corresponding dose enhancement over time due to GNP released from such GNP-loaded brachytherapy spacers (GBS). Method and Materials: An experimentally determined intratumoral diffusion coefficient (D) for 10-nm nanoparticles was used to estimate D for other sizes by using the Stokes-Einstein equation. GNP concentration profiles, obtained using D, were then used to calculate the corresponding dose enhancement factor (DEF) for each tumor voxel, using dose painting-by-numbers approach, for times relevant to the considered brachytherapy sources' lifetimes. The investigation was carried out as a function of GNP size for the clinically applicable low-dose-rate brachytherapy sources iodine-125 (I-125), palladium-103 (Pd-103), and cesium-131 (Cs-131). Results: Results showed that dose enhancement to tumor voxels and subvolumes during brachytherapy can be customized by varying the size of GNP released or eluted from the GBS. For example, using a concentration of 7 mg/g GNP, significant DEF (>20%) could be achieved 5 mm from a GBS after 5, 12, 25, 46, 72, 120, and 195 days, respectively, for GNP sizes of 2, 5, 10, 20, 30, and 50 nm and for 80 nm when treating with I-125. Conclusions: Analyses showed that using Cs-131 provides the highest dose enhancement to tumor voxels. However, given its relatively longer half-life, I-125 presents the most flexibility for customizing the dose enhancement as a function of GNP size. These findings provide a useful reference for further work toward development of potential new brachytherapy application

    Full Text Available Background: Violence against women is an important public-health problem that draws attention of a wide spectrum of clinicians. However, multiple barriers undermine the efforts of primary health care workers to properly manage and deal with battered women. Objectives: The aim of the present study was to reveal barriers that might impede administering comprehensive health care to battered women and compare these barriers between nurses and physicians and identify factors affecting such barriers. Methods: A total of 1553 medical staff from 78 primary health care units agreed to share in this study, of these 565 were physicians and 988 were nurses. Results: Barriers related to the battered woman topped the list of ranks for both physicians (93.1 ± 17.4% and nurses (82.1 ± 29.3%. Institutional barriers (87.2 ± 21.5%, barriers related to the health staff (79.8 ± 20. 5%, and social barriers (77.5 ± 21.7% followed, respectively, in the rank list of physicians while for the list of nurses, social barriers (75.1 ± 30.1%, institutional barriers (74.3 ± 31.7% followed with barriers related to health staff (70.0 ± 30.0% at the bottom of the list. Only duration spent at work and degree of education of nurses were significantly affecting the total barrier score, while these factors had no significant association among physicians. Conclusion: Real barriers exist that might interfere with administering proper comprehensive health care at the primary health care units by both physicians and nurses. This necessitates design of specific programs to improve both the knowledge and skills of the medical staff to deal with violence among women. Also, available resources and infrastructure must be strengthened to face this problem and enable primary health care staff to care for battered women.

    Using a sample of galaxy groups found in the Sloan Digital Sky Survey Data Release 4, we measure the following four types of alignment signals: (1) the alignment between the distributions of the satellites of each group relative to the direction of the nearest neighbor group (NNG); (2) the alignment between the major axis direction of the central galaxy of the host group (HG) and the direction of the NNG; (3) the alignment between the major axes of the central galaxies of the HG and the NNG; and (4) the alignment between the major axes of the satellites of the HG and the direction of the NNG. We find strong signal of alignment between the satellite distribution and the orientation of central galaxy relative to the direction of the NNG, even when the NNG is located beyond 3r vir of the host group. The major axis of the central galaxy of the HG is aligned with the direction of the NNG. The alignment signals are more prominent for groups that are more massive and with early-type central galaxies. We also find that there is a preference for the two major axes of the central galaxies of the HG and NNG to be parallel for the system with both early central galaxies, however, not for the systems with both late-type central galaxies. For the orientation of satellite galaxies, we do not find any significant alignment signals relative to the direction of the NNG. From these four types of alignment measurements, we conclude that the large-scale environment traced by the nearby group affects primarily the shape of the host dark matter halo, and hence also affects the distribution of satellite galaxies and the orientation of central galaxies. In addition, the NNG directly affects the distribution of the satellite galaxies by inducing asymmetric alignment signals, and the NNG at very small separation may also contribute a second-order impact on the orientation of the central galaxy in the HG.

    Background Focal Electrically-Administered Therapy (FEAT) is a new method of transcranial electrical stimulation capable of focal modulation of cerebral activity. Other than invasive studies in animals and examination of motor output in humans, there are limited possibilities for establishing basic principles about how variation in stimulus parameters impact on patterns of intracortical stimulation. This study used a simpler paradigm, and evaluated the effects of different stimulation parameters on subjective perception of the quality and location of scalp pain. Methods In two studies, 19 subjects were randomly stimulated over the left forehead, varying the anode-cathode arrangement, the intensity of stimulation, the electrode size and placement, and whether the current flow was unidirectional or bidirectional. Subjects rated the location of the sensation, and its quality. Results The perceived center of stimulation moved toward the cathode, regardless of placement. This shift in subjective sensation was more prominent when the electricity was unidirectional. Additionally, more intense stimulation, as well as stimulation with a smaller electrode, caused greater perceived pain. Unidirectional stimulation was rated more painful when traveling from a large anode to a small cathode and less painful when traveling from a small anode to a large cathode. Finally, participants were more likely to perceive the electrical stimulation as moving towards a specific direction when the intensity was high than when it was low. Conclusions The intensity and location of sensations can be manipulated by varying the intensity, current direction, or geometry of electrodes. PMID:19092677

    2018-03-01

    Physician-administered euthanasia (PAE) was legalized, along with physician-assisted suicide (PAS), in The Netherlands in 2001. Annual reports of the Dutch Regional Euthanasia Review Committees, the committees' 2015 published Code of Practice and research studies. There is a general openness about the practice of PAE/PAS in The Netherlands and an avoidance of misleading euphemisms. The 2001 law also includes arrangements for post-event review of PAE/PAS decisions. Rising numbers of annually reported deaths from PAE and uncertainty over actual numbers. Movement away from the principle that euthanasia must take place within an established doctor-patient relationship. Increasing extension of the 2001 law to people with mental health conditions, dementia and multiple co-morbidities. Nature of the post-event scrutiny applied to reported cases. The predominance of PAE over PAS where both are legalized raises questions over how these two acts are perceived and whether there are implications for such laws. Are the criteria for PAE/PAS in the 2001 law appropriate for a law of this nature? What should be the respective roles of the second-opinion doctors and the review committees?

  20. Antimalarial Activity of Orally Administered Curcumin Incorporated in Eudragit®-Containing Liposomes

    Full Text Available Curcumin is an antimalarial compound easy to obtain and inexpensive, having shown little toxicity across a diverse population. However, the clinical use of this interesting polyphenol has been hampered by its poor oral absorption, extremely low aqueous solubility and rapid metabolism. In this study, we have used the anionic copolymer Eudragit® S100 to assemble liposomes incorporating curcumin and containing either hyaluronan (Eudragit-hyaluronan liposomes or the water-soluble dextrin Nutriose® FM06 (Eudragit-nutriosomes. Upon oral administration of the rehydrated freeze-dried nanosystems administered at 25/75 mg curcumin·kg−1·day−1, only Eudragit-nutriosomes improved the in vivo antimalarial activity of curcumin in a dose-dependent manner, by enhancing the survival of all Plasmodium yoelii-infected mice up to 11/11 days, as compared to 6/7 days upon administration of an equal dose of the free compound. On the other hand, animals treated with curcumin incorporated in Eudragit-hyaluronan liposomes did not live longer than the controls, a result consistent with the lower stability of this formulation after reconstitution. Polymer-lipid nanovesicles hold promise for their development into systems for the oral delivery of curcumin-based antimalarial therapies.

    Conjugated linoleic acid (CLA) is one of the constituents of animal products with possible health benefits such as anti-carcinogenic and anti-obesity effects. In this study, we investigated the immunomodulatory effects of CLA using a mouse model of allergic dermatitis. Mice were orally administered either a CLA mixture containing equal amounts of 9c, 11 t-CLA and 10 t, 12c-CLA, or high linoleic acid safflower oil, and allergic dermatitis was induced on the ear by repeated topical applications of oxazolone. Oral administration of the CLA mixture but not the high linoleic safflower oil attenuated the symptoms of allergic dermatitis in both ear weights and clinical scores. This effect was associated with decreased levels of ear interleukin-4 (IL-4) and plasma immunoglobulin E. The immunomodulatory effects of the CLA isomers were compared by an in vitro cytokine production assay. The results showed that 9c, 11 t-CLA, the most predominant isomer in animal products, significantly inhibited IL-4 and interferon-γ production from mouse splenocytes with similar potency to 10 t, 12c-CLA. These findings suggest that CLA, a constituent of animal products, has a potentially beneficial effect for amelioration of allergic dermatitis. © 2016 Japanese Society of Animal Science.

    Portosystemic shunting was evaluated with rectal administration of iodine-123 iodoamphetamine (IMP) in seven patients without liver disease and 53 patients with liver cirrhosis. IMP (2-3 mCi [74-111 MBq]) was administered to the rectum through a catheter. Images of the chest and abdomen were obtained for up to 60 minutes with a scintillation camera interfaced with a computer. In all patients, images of the liver and/or lungs were observed within 5-10 minutes and became clear with time. In patients without liver disease, only liver images could be obtained, whereas the lung was visualized with or without the liver in all patients with liver cirrhosis. The portosystemic shunt index was calculated by dividing counts of lungs by counts of liver and lung. These values were significantly higher in liver cirrhosis, especially in the decompensated stage. Transrectal portal scintigraphy with IMP appears to be a useful method for noninvasive and quantitative evaluation of portosystemic shunting in portal hypertension

    This regulatory analysis was developed to respond to three petitions for rulemaking to amend 10 CFR parts 20 and 35 regarding release of patients administered radioactive material. The petitions requested revision of these regulations to remove the ambiguity that existed between the 1-millisievert (0.1-rem) total effective dose equivalent (TEDE) public dose limit in Part 20, adopted in 1991, and the activity-based release limit in 10 CFR 35.75 that, in some instances, would permit release of individuals in excess of the current public dose limit. Three alternatives for resolution of the petitions were evaluated. Under Alternative 1, NRC would amend its patient release criteria in 10 CFR 35.75 to match the annual public dose limit in Part 20 of 1 millisievert (0.1 rem) TEDE. Alternative 2 would maintain the status quo of using the activity-based release criteria currently found in 10 CFR 35.75. Under Alternative 3, the NRC would revise the release criteria in 10 CFR 35.75 to specify a dose limit of 5 millisieverts (0.5 rem) TEDE.

    Systemically administered 3-nitropropionic acid (3- NPA), irreversible inhibitor of succinate dehydrogenase, produced characteristic bilateral lesions in the striatum (STR) in the rat. Inside the lesion, neutrophils invaded and strong immunoreaction for IgG as well as complement factor C3b/C4b receptor (C3b/C4br) were observed. The core of the lesion lost the immunoreaction for glial fibrillary acidic protein (GFAP) while the marginal area had abundant GFAP-labeled astrocytes around the vessels. Intoxicated rats often became somnolent and were awkward in cooperative movement on a pole climbing test, but they had a quite good memory retention in a passive avoidance learning. Muscle tonus in some of the intoxicated rats became hypotonic with low voltage electromyogram (EMG) activity, especially in lower limbs. In summary, 3-NPA intoxicated rats had selective bilateral lesions in the STR and exhibited disturbances in a cooperative movement owing to the impairment in muscle tonus, thus it would be a useful animal model to deduce the central pathogenesis of Huntington's disease.

  5. Comparison of radioisotopic studied calcium metabolism in the orally administered and inhaled cadmium rat

    The radioisotopic study of calcium metabolism in the rat after oral administration of cadmium, 8 mg/kg during 13 weeks, has shown two different effects of this ion: 1) in the intestine, cadmium inhibits the absorption of calcium by active transport; 2) in the deep bone compartment, the decrease of the bone calcium used for the crystallization and slowly exchangeable with the calcium central pool (serum, extracellular and soft tissues calcium) is combined with a reduction of the exchange rates between the two compartments. When administered through a microparticle aerosol inhalation (1 mg/m 3 of air, 30 mn a day, during 12 weeks), cadmium's main target organ is the deep bone compartment. For both modes of administration, the slowing down of osteogenesis is confirmed by a drop in serum alkaline phosphatase after a four weeks period which reflects a decrease of the osteoblastic activity. Therefore it appears that the effects on bones observed during the chronic oral cadmium administration, do not result from a malabsorption of intestine calcium but also from the very action the Cd ++ ion on the bone crystallization process [fr

    Central nervous system (CNS) prophylaxis is required during initial treatment of non-Hodgkin lymphoma (NHL) subtypes that carry a high risk of CNS involvement. Intrathecal (IT) liposomal cytarabine, a formulation with prolonged half-life, has been shown to be safe and effective in the treatment of meningeal disease in patients with high-grade lymphoma. We retrospectively reviewed all adult patients with high-grade NHL that received prophylactic therapy with IT liposomal cytarabine and developed neurologic complications in our institution between April 2007 and May 2009. We recorded information on hospital admission, chemotherapy regimens, clinical features, neuroimaging, cerebrospinal fluid, neurophysiology data, and outcome. Neurotoxicity was graded according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC). Four of fourteen patients (28%) developed moderate or severe neurotoxicity (grades 2 and 3 of the NCI-CTC), manifested as conus medullaris/cauda equine syndrome or pseudotumour cerebri-like syndrome, after a median of 3.5 IT courses of liposomal cytarabine. All patients had received corticosteroids to prevent arachnoiditis. Liposomal cytarabine given via the IT route, even with concomitant corticosteroid administration, can result in significant neurotoxicity in some patients. We discuss the potential pathogenesis of these effects and suggest hypothetical therapeutic measures to prevent these complications. Specialists should be aware of these possible complications when administering prophylactic IT liposomal cytarabine in high-grade NHL patients, and additional prospective studies should be conducted to more clearly delineate the frequency and characteristics of these complications.

    It has been suggested that impaired gut absorption of copper is the cause of the exacerbated copper deficiency signs in rats fed fructose when compared to rats fed starch. The present study was designed to examine how rats fed fructose or starch diets, either copper-deficient or supplemented, distributed and excreted 67 Cu when the isotope was administered i.p. Intraperitoneal administration was chosen in an effort to circumvent primary gut absorption as a factor in the metabolism of 67 Cu. After 7 wk of dietary treatment, rats received an i.p. injection of 67 Cu and were placed in metabolic cages for 4 d. Regardless of dietary carbohydrate, copper-deficient rats retained similar levels of radioactivity in various tissues and excreted similar amounts of 67 Cu in feces and urine. This similarity in copper metabolism in copper-deficient rats fed either fructose or starch when the gut was circumvented for isotope administration suggests that the gut could be responsible, at least in part, for the exacerbated signs associated with the copper deficiency in rats fed fructose. The possibility is discussed that alterations in metabolism may increase the requirement for copper when fructose is the main dietary carbohydrate

    Full Text Available Advax, a delta inulin-derived microparticle, has been developed as an adjuvant for several vaccines. However, its immunological characteristics and potential mechanism of action are yet to be elucidated. Here, we show that Advax behaves as a type-2 adjuvant when combined with influenza split vaccine, a T helper (Th2-type antigen, but behaves as a type-1 adjuvant when combined with influenza inactivated whole virion (WV, a Th1-type antigen. In addition, an adjuvant effect was not observed when Advax-adjuvanted WV vaccine was used to immunize toll-like receptor (TLR 7 knockout mice which are unable to respond to RNA contained in WV antigen. Similarly, no adjuvant effect was seen when Advax was combined with endotoxin-free ovalbumin, a neutral Th0-type antigen. An adjuvant effect was also not seen in tumor necrosis factor (TNF-α knockout mice, and the adjuvant effect required the presences of dendritic cells (DCs and phagocytic macrophages. Therefore, unlike other adjuvants, Advax potentiates the intrinsic or in-built adjuvant property of co-administered antigens. Hence, Advax is a unique class of adjuvant which can potentiate the intrinsic adjuvant feature of the vaccine antigens through a yet to be determined mechanism.

    Methylphenidate and 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') are widely misused psychoactive drugs. Methylphenidate increases brain dopamine and norepinephrine levels by blocking the presynaptic reuptake transporters. MDMA releases serotonin, dopamine and norepinephrine through the same transporters. Pharmacodynamic interactions of methylphenidate and MDMA are likely. This study compared the pharmacodynamic and pharmacokinetic effects of methylphenidate and MDMA administered alone or in combination in healthy subjects using a double-blind, placebo-controlled, crossover design. Methylphenidate did not enhance the psychotropic effects of MDMA, although it produced psychostimulant effects on its own. The haemodynamic and adverse effects of co-administration of methylphenidate and MDMA were significantly higher compared with MDMA or methylphenidate alone. Methylphenidate did not change the pharmacokinetics of MDMA and vice versa. Methylphenidate and MDMA shared some subjective amphetamine-type effects; however, 125 mg of MDMA increased positive mood more than 60 mg of methylphenidate, and methylphenidate enhanced activity and concentration more than MDMA. Methylphenidate and MDMA differentially altered facial emotion recognition. Methylphenidate enhanced the recognition of sad and fearful faces, whereas MDMA reduced the recognition of negative emotions. Additionally, the present study found acute pharmacodynamic tolerance to MDMA but not methylphenidate. In conclusion, the combined use of methylphenidate and MDMA does not produce more psychoactive effects compared with either drug alone, but potentially enhances cardiovascular and adverse effects. The findings may be of clinical importance for assessing the risks of combined psychostimulant misuse.

    Granulocyte colony-stimulating factor (G-CSF) is present in liquids swallowed by the fetus and neonate; specifically, amniotic fluid, colostrum, and human milk. The swallowed G-CSF has local effects on enteric cells, which express the G-CSF receptor. However, some portion of the G-CSF ingested by the fetus and neonate might be absorbed into the circulation and have systemic actions, such as stimulating neutrophil production. To assess this possibility we sought to determine if circulating G-CSF concentrations of neonates increase after enteral administration of recombinant human granulocyte colony-stimulating factor (rhG-CSF). This was a single-center, prospective, blinded, randomized, 2 x 2 crossover study, with each infant receiving 1 dose of rhG-CSF (100 microg/kg) and 1 dose of placebo. Plasma G-CSF concentrations were measured at 2 and 4 hours after administration of the test solution. No significant change in plasma G-CSF concentration was observed after the enteral administration of rhG-CSF. On this basis, we conclude that orally administered rhG-CSF is not absorbed in significant quantities, and we speculate that the G-CSF swallowed by the fetus and neonate has local but not systemic effects.

    Cabazitaxel is approved in patients with metastatic hormone-refractory prostate cancer previously treated with a docetaxel-containing regimen. This study evaluated a weekly cabazitaxel dosing regimen. Primary objectives were to report dose-limiting toxicities (DLTs) and to determine the maximum tolerated dose (MTD). Efficacy, safety and pharmacokinetics were secondary objectives. Cabazitaxel was administered weekly (1-hour intravenous infusion at 1.5–12 mg/m2 doses) for the first 4 weeks of a 5-week cycle in patients with solid tumours. Monitoring of DLTs was used to determine the MTD and the recommended weekly dose. Thirty-one patients were enrolled. Two of six patients experienced DLTs at 12 mg/m 2 , which was declared the MTD. Gastrointestinal disorders were the most common adverse event. Eight patients developed neutropenia (three ≥ Grade 3); one occurrence of febrile neutropenia was reported. There were two partial responses (in breast cancer) and 13 patients had stable disease (median duration of 3.3 months). Increases in C max and AUC 0–t were dose proportional for the 6–12 mg/m 2 doses. The MTD of weekly cabazitaxel was 12 mg/m 2 and the recommended weekly dose was 10 mg/m 2 . The observed safety profile and antitumour activity of cabazitaxel were consistent with those observed with other taxanes in similar dosing regimens. The study was registered with ClinicalTrials.gov as http://www.clinicaltrials.gov/ct2/show/NCT01755390

    The nanotoxicology as a new subdiscipline of nanotechnology needs to be studied in vivo. To do so, it is essential to understand certain pharmacological information of the nanoparticles in vivo. Silica nanoparticles (SiNPs) have been developed for a number of biomedical uses; however, research on their tissular localization and excretion has been limited. In this study, we analyzed the localization of intravenously administered SiNPs with sizes of 20 and 80 nm in liver and spleen and quantitatively investigated the excretion of SiNPs through urine and feces. The results of the tissular localization study showed that the SiNPs were located in liver evenly; however, they were mainly accumulated in the white pulp of spleen. The quantitative excretory assay found the renal excretion being the main excretion pathway of SiNPs and indicated that the accumulated excretory rate of 80 nm SiNPs through urine was higher than that of 20 nm SiNPs because of the higher hemoconcentration. Further analysis of radioactive substances in the excreta showed the convincing confirmatory evidence that the SiNPs of both the sizes of 20 and 80 nm could be excreted through urine. These results provide important information on in vivo distribution and excretion of SiNPs.

    A calibration service was introduced in 1986 to assist the Canadian nuclear medicine community in determining more accurately the amount of radioactive material administered to patients for either diagnostic or therapeutic purposes. This aspect of a quality assurance program in nuclear medicine provides an accuracy check on instruments and the technologists using them. The calibration report issued constitutes direct traceability of a facility to a national standards laboratory. Nuclides most frequently calibrated are 99m Tc and 131 I. Others include 67 Ga, 111 In, 123 I, 125 I and 201 Tl. All samples received are analysed for radionuclidic impurities by high-resolution X-ray and gamma-ray spectrometry. Ten years of testing has shown that, except for a few conscientious departments, accuracy checks on radionuclide (dose) calibrators are not a high priority. There are 285 nuclear medicine facilities in Canada and, since there is no legal requirement that the calibrators be checked for accuracy, only 29 have had their instruments checked using this service. Of these, 14 perform annual accuracy checks with NRCC. In this paper, the results of the intercomparisons are described, and quality control problems associated with the use of radionuclide calibrators in nuclear medicine are discussed

    Although prefrontal and hippocampal neurons are critical for spatial working memory,the function of glial cells in spatial working memory remains uncertain.In this study we investigated the function of glial cells in rats’ working memory.The glial cells of rat brain were inhibited by intracerebroventricular(icv) injection of fluorocitrate(FC).The effects of FC on the glial cells were examined by using electroencephalogram(EEG) recordings and delayed spatial alternation tasks.After icv injection of 10 μL of 0.5 nmol/L or 5 nmol/L FC,the EEG power spectrum recorded from the hippocampus increased,but the power spectrum for the prefrontal cortex did not change,and working memory was unaffected.Following an icv injection of 10 μL of 20 nmol/L FC,the EEG power spectra in both the prefrontal cortex and the hippocampus increased,and working memory improved.The icv injection of 10 μL of 50 nmol/L FC,the EEG power spectra in both the prefrontal cortex and in the hippocampus decreased,and working memory was impaired.These results suggest that spatial working memory is affected by centrally administered FC,but only if there are changes in the EEG power spectrum in the prefrontal cortex.Presumably,the prefrontal glial cells relate to the working memory.

    Self-administered survey questionnaires are an important data collection tool in clinical practice, public health research and epidemiology. They are ideal for achieving a wide geographic coverage of the target population, dealing with sensitive topics and are less resource-intensive than other data collection methods. These survey questionnaires can be delivered electronically, which can maximise the scalability and speed of data collection while reducing cost. In recent years, the use of apps running on consumer smart devices (i.e., smartphones and tablets) for this purpose has received considerable attention. However, variation in the mode of delivering a survey questionnaire could affect the quality of the responses collected. To assess the impact that smartphone and tablet apps as a delivery mode have on the quality of survey questionnaire responses compared to any other alternative delivery mode: paper, laptop computer, tablet computer (manufactured before 2007), short message service (SMS) and plastic objects. We searched MEDLINE, EMBASE, PsycINFO, IEEEXplore, Web of Science, CABI: CAB Abstracts, Current Contents Connect, ACM Digital, ERIC, Sociological Abstracts, Health Management Information Consortium, the Campbell Library and CENTRAL. We also searched registers of current and ongoing clinical trials such as ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform. We also searched the grey literature in OpenGrey, Mobile Active and ProQuest Dissertation & Theses. Lastly, we searched Google Scholar and the reference lists of included studies and relevant systematic reviews. We performed all searches up to 12 and 13 April 2015. We included parallel randomised controlled trials (RCTs), crossover trials and paired repeated measures studies that compared the electronic delivery of self-administered survey questionnaires via a smartphone or tablet app with any other delivery mode. We included data obtained from

    Full Text Available Acquired methemoglobinemia is an uncommon hemoglobinopathy that results from exposure to oxidizing agents, such as chemicals or medications. Although, as reported in the adult population, it happens most often due to prescribed medication or procedural anesthesia and not due to easily accessed over-the-counter medications, the authors will describe an otherwise healthy male adult with no known medical history and no prescribed medications, who presented to the emergency department reporting generalized weakness, shortness of breath, headache, dizziness, and pale gray skin. In addition, the patient reported that he also had a severe toothache for several days, which he had been self-treating with an over-the-counter oral benzocaine gel. Ultimately, the diagnosis of methemoglobinemia was made by clinical history, physical examination, and the appearance of chocolate-colored blood and arterial blood gas (ABG with cooximetry. After 2 mg/kg of intravenous methylene blue was administered, the patient had complete resolution of all signs and symptoms. This case illustrates that emergency physicians should be keenly aware of the potential of toxic hemoglobinopathy secondary to over-the-counter, nonprescribed medications. Discussion with patients regarding the dangers of inappropriate use of these medicines is imperative, as such warnings are typically not evident on product labels.

  19. The ABCs of LDAP how to install, run, and administer LDAP services

    Until now, it has been difficult to find the right source of information on LDAP and directory server implementations: books on the subject are overly product-specific, and a search on the Web results in information overload. The ABCs of LDAP: How to Install, Run, and Administer LDAP Services strikes the right balance, providing a synopsis of LDAP fundamentals without getting wrapped up in one particular implementation.This book is for network and systems administrators who want to begin using LDAP more extensively. It delivers the theoretical background needed to understand how these servers work, resulting in clear, concise examples of implementations in both commercial and OpenLDAP environments.The text is structured so that each chapter can stand on its own, with brief descriptions of terms supplemented by references to more detailed explanations in other chapters. You also benefit from a concise overview of how to design a directory, preparing you to execute directory deployments for email, PKI, DNS, NIS...

    A self-administered foot evaluation questionnaire (SAFE-Q) was developed by the Japanese Society for Surgery of the Foot (JSSF). The aim of this study is to evaluate the validity and responsiveness of the SAFE-Q in patients with rheumatoid arthritis (RA). In total, 180 patients with RA answered the SAFE-Q. Of 180 patients, 34 answered the SAFE-Q twice, preoperatively and postoperatively, to assess responsiveness. Construct validity was tested by comparing the 5 SAFE-Q subscales and the JSSF standard rating system for the RA foot and ankle scale (JSSF-RA), a Japanese version of the Health Assessment Questionnaire (JHAQ), disease activity score in 28 joints (DAS28), simplified disease activity index (SDAI), and clinical disease activity index (CDAI). Responsiveness was examined by calculating the standardized response mean (SRM) and effect size (ES) 3 months after surgery. There were moderate correlations between the SAFE-Q and the JSSF-RA and JHAQ. Conversely, a low correlation was observed between the SAFE-Q and DAS28, SDAI, and CDAI. The responsiveness was high, with an SRM of 0.9 and ES of 0.7 for pain subscales. SAFE-Q is a useful tool for assessing the foot and ankle in RA patients.
