    Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common X-linked inherited enzymopathic disorder affecting more than 500 million people worldwide. It has so far been linked to 217 distinct genetic variants in the exons and exon-intron boundaries of the G6PD gene, giving rise to a wide range of biochemical heterogeneity and clinical manifestations. Reports from different settings suggested the association of intronic and other mutations outside the reading frame of the G6PD gene with reduced enzyme activity and presenting clinical symptoms. The present study aimed to investigate any association of other variations apart of the exonic or exonic intronic boundaries in the development of G6PD deficiency. Sixty-seven unrelated Palestinian children admitted to the pediatric hospital with hemolytic crises due to G6PD deficiency were studied. In our Palestinian cohort of 67 [59 males (M) and 8 females (F)] G6PD-deficient children, previously hospitalized for acute hemolytic anemia due to favism, molecular sequencing of the G6PD gene revealed four cases (3M and 1F) that did not have any of the variants known to cause G6PD deficiency, but the 3' UTR c.*+357A>G (rs1050757) polymorphism in association with IVS 11 (c.1365-13T>C; rs2071429), and c.1311C>T (rs2230037). We now provide an additional evidence form Palestinian G6PD-deficient subjects for a possible role of 3' UTR c.*+357 A>G, c.1365-13T>C, and/or c.1311C>T polymorphism for G6PD deficiency, suggesting that not only a single variation in the exonic or exonic intronic boundaries, but also a haplotype of G6PD should considered as a cause for G6PD deficiency.

  2. Should Pharmacy Technicians Administer Immunizations?

    Full Text Available Purpose. To describe the potential role for pharmacy technicians in administering immunizations – limited for this discussion to specifically inserting the needle into the patient’s arm and pressing down on the plunger – at the discretion of a supervising pharmacist as a way to enhance patient care and workflow efficiency. Summary. Pharmacy technicians currently play an important role in facilitating pharmacy-based immunization programs. Technicians routinely perform non-clinical tasks related to pharmacy-based immunizations, though nearly all states prohibit technicians from administering vaccines. Several studies demonstrate that untrained laypersons can safely administer intranasal or intradermal vaccines, and laypersons routinely administer medications through intramuscular or subcutaneous routes (e.g., patients with diabetes or rheumatic conditions. It stands to reason that a trained pharmacy technician could perform comparably on these techniques that laypersons have mastered. One state has adopted rules to allow pharmacy technicians to administer immunizations if the technician has completed specific training on administration techniques and on basic life support. This task is performed at the discretion of the supervising pharmacist, and the pharmacist would still be responsible for clinical aspects of immunizing such as prescribing the right vaccine to the right patient. Additional considerations factoring into the decision as to whether or not to involve pharmacy technicians in immunization administration are also summarized. Conclusion. If safety can be reasonably assured through training and supervision, it may be appropriate to delegate vaccine administration to appropriately trained pharmacy technicians. Such delegation may enhance workflow efficiency, which may confer added value for patient care and potentially improve access to community pharmacy-based immunizations.   Type: Commentary

    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.

    Stuttering modification techniques can be used effectively in the school setting. In fact, speech-language pathologists can use this environment to their advantage to address not only disfluency but also the emotional and behavioral aspects of stuttering. Toward this end, stuttering modification goals and techniques are outlined, with a discussion of how to adapt them to school environments. Specific topics include writing clear, measurable IEP goals, taking advantage of the school setting to implement these goals, administering stuttering modification within a group therapy mode, involving parents and teachers, and monitoring progress.

    2015-01-01

    Introduction The eye is considered as the most privileged organ because of the blood–ocular barrier that acts as a barrier to systemically administered xenobiotics. However, there has been a significant increase in the number of reports on systemic drug-induced ocular complications. If such complications are left untreated, then it may cause permanent damage to vision. Hence, knowledge of most recent updates on ever-increasing reports of such toxicities has become imperative to develop better therapy while minimizing toxicities. Areas covered The article is mainly divided into anterior and posterior segment manifestations caused by systemically administered drugs. The anterior segment is further elaborated on corneal complications where as the posterior segment is focused on optic nerve, retinal and vitreous complications. Furthermore, this article includes recent updates on acute and chronic ocular predicaments, in addition to discussing various associated symptoms caused by drugs. Expert opinion Direct correlation of ocular toxicities due to systemic drug therapy is evident from current literature. Therefore, it is necessary to have detailed documentation of these complications to improve understanding and predict toxicities. We made an attempt to ensure that the reader is aware of the characteristic ocular complications, the potential for irreversible drug toxicity and indications for cessation. PMID:22803583

    2009-12-01

    As most anticancer drugs are cytotoxic, their safe and error-free application is important. We analyzed data from the hematology-oncology ward chemotherapy checklist dated January 13th through February 3rd, 2007 and found accuracy rates for chemotherapy drug usage as low as 68.4%. Possible causes identified for this poor result include incomplete chemotherapy standards protocols, lack of chemotherapy quality control, and insufficient chemotherapy knowledge amongst nursing staff. This project aimed to improve the accuracy of nursing staff in administering chemotherapy and to raise nursing staff knowledge regarding chemotherapy. Our strategies for improvement included completing a chemotherapy standards protocol, establishing a chemotherapy quality-control monitoring system, augmenting chemotherapy training and adding appropriate equipment and staff reminders. After strategies were implemented, accuracy in chemotherapy administration rose to 96.7%. Related knowledge amongst nursing staff also improved from an initial 77.5% to 89.2%. Implementing the recommended measures achieved a significant improvement in the accuracy and quality of chemotherapy administered by nursing personnel.

  13. System and method for administering radiation

    International Nuclear Information System (INIS)

    Vogel, T.M.

    1975-01-01

    A system and method for metering the quantity of radiation administered a subject by a source of radiation movable along a path relative to the subject is described. The system cumulatively counts the amount of radiation directed toward the subject during each of a succession of increments of motion of the source. When a predetermined amount of radiation is delivered during an increment, the source is disabled until the source passes into the next increment of displacement. The count of radiation is restarted at the instant the source is disabled, to accumulate accurately any added spurious radiation dosage which may occur and to include that dosage in the count of the permitted amount for the next succeeding increment of motion. Several interlocks for disabling the system in response to various malfunctions are included. Means for controlling the speed of movement of the source and/or the dose rate of the source are also included. (auth)

  14. 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.

    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.

    2017-12-01

    The current pilot study aimed to assess whether reporting quality would decline materially in adolescents completing weekly web-based Automated Self-Administered 24-Hour dietary recalls (ASA24-Kids-2014) and interviewer-administered 24 h dietary recalls for six weeks. We also aimed to assess method preference. We conducted two studies. Study 1 (n 20) randomized participants to complete either one ASA24-Kids-2014 or one interviewer-administered recall weekly, for six weeks. Energy intake and number of foods reported were described for each method over time. Differences between recall methods for each measure were tested using mixed-effects regression. Study 2 (n 10) employed a randomized crossover design to describe method preference. Dietary intake was collected either by telephone (interviewer-administered dietary recalls) or via the Internet (ASA24-Kids-2014 dietary recalls). Adolescents aged 12-17 years with no prior diet recording experience were enrolled. In Study 1, mean (sd) total energy and number of foods reported decreased by 50 (222) kJ (12 (53) kcal) and 0·05 (0·31) items v. 38 (138) kJ (9 (33) kcal) and 0·17 (0·14) items per recall for participants randomized to the ASA24-Kids-2014 v. interviewer-administered recalls, respectively. There was no difference between groups for either measure (P > 0·57). In Study 2, eight of ten participants preferred the interviewer-administered recall over the ASA24-Kids-2014. Overall, seven of twenty participants experienced technical difficulties with the ASA24-Kids-2014. No appreciable decay in reporting quality was seen for either method. However, participants reported a preference for the interviewer-administered recall. Our findings can help inform and support larger studies to further characterize the performance of the ASA24 in adolescents.

  9. Administering chemotherapy in nononcology settings: a case study.

    Science.gov (United States)

    Smith, Nancy

    2011-08-01

    Providing chemotherapy for patients in a variety of settings may be a challenge for oncology nurses. Increased acuity and comorbidities of patients needing chemotherapy have resulted in a greater incidence of administration in nononcology settings, such as intensive care units (ICUs). In addition, patients with conditions other than cancer are receiving chemotherapy. Because of a lack of certified and experienced chemotherapy nurses in the ICU, oncology nurses may be pulled from their unit to administer chemotherapy. Another possibility is that nonchemotherapy-certified nurses may be asked to administer chemotherapy. Caring for patients receiving chemotherapy may be stressful for nononcology nurses because of their lack of knowledge regarding chemotherapy precautions and the management of side effects and toxicities. Not only is coordination and cooperation between nursing personnel vital, certified oncology nurses must be able to assess the situation, provide the necessary information and education, and safely administer the chemotherapy. This article describes a case study and provides suggestions for planning in similar situations.

  18. Statistical analysis of Japanese Thorotrast-administered autopsy cases

    International Nuclear Information System (INIS)

    Mori, T.; Kato, Y.; Shimamine, T.; Watanabe, S.

    1979-01-01

    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

    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.

    Näppä, Ulla; Rasmussen, Birgit H; Axelsson, Bertil; Lindqvist, Olav

    2014-12-01

    Palliative chemotherapy treatments (PCT) are becoming more common for patients with incurable cancer; a basic challenge is to optimize tumour response while minimizing side-effects and harm. As registered nurses most often administer PCT, they are most likely to be confronted with difficult situations during PCT administration. This study explores challenging situations experienced by nurses when administering PCT to patients with incurable cancer. Registered nurses experienced in administering PCT were asked in interviews to recall PCT situations they found challenging. Inspired by the narrative tradition, stories were elicited and analysed using a structural and thematic narrative analysis. A total of twenty-eight stories were narrated by seventeen nurses. Twenty of these were dilemmas that could be sorted into three storylines containing one to three dilemmatic situations each. The six dilemmatic situations broadly related to three interwoven areas: the uncertainty of the outcome when giving potent drugs to vulnerable patients; the difficulty of resisting giving PCT to patients who want it; and insufficient communication between nurses and physician. Nurses who administer PCT are engaged in a complex task that can give rise to a number of dilemmatic situations. The findings may be interpreted as meaning that at least some situations might be preventable if the knowledge and insight of all team members - nurses, physicians, patients, and relatives - are jointly communicated and taken into account when deciding whether or not to give PCT. Forming palliative care teams early in the PCT trajectory, could be beneficial for staff and patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

  10. Absorption sites of orally administered drugs in the small intestine.

    Science.gov (United States)

    Murakami, Teruo

    2017-12-01

    In pharmacotherapy, drugs are mostly taken orally to be absorbed systemically from the small intestine, and some drugs are known to have preferential absorption sites in the small intestine. It would therefore be valuable to know the absorption sites of orally administered drugs and the influencing factors. Areas covered:In this review, the author summarizes the reported absorption sites of orally administered drugs, as well as, influencing factors and experimental techniques. Information on the main absorption sites and influencing factors can help to develop ideal drug delivery systems and more effective pharmacotherapies. Expert opinion: Various factors including: the solubility, lipophilicity, luminal concentration, pKa value, transporter substrate specificity, transporter expression, luminal fluid pH, gastrointestinal transit time, and intestinal metabolism determine the site-dependent intestinal absorption. However, most of the dissolved fraction of orally administered drugs including substrates for ABC and SLC transporters, except for some weakly basic drugs with higher pKa values, are considered to be absorbed sequentially from the proximal small intestine. Securing the solubility and stability of drugs prior to reaching to the main absorption sites and appropriate delivery rates of drugs at absorption sites are important goals for achieving effective pharmacotherapy.

    There is greater incentive than ever to keep individuals requiring injectable or infusion therapy in the nursing facility-and not transfer them to a hospital-to receive those services. There is a demand for pharmacists with the skills, knowledge, and training to provide these services. To make that possible, pharmacies and pharmacists with the proper equipment, supplies, knowledge, training, and expertise are needed to work closely with physicians and nurses to provide sterile, properly compounded products and ensure that drugs are administered appropriately and in the right doses. These pharmacists also can work with facilities and practitioners to assess, improve, and document quality.

    Rats were made to drink D2O mixed water (30: 70) for 6 weeks in order to study the biological effects of orally administered D2O on the liver. Heavy water administration results in gradual decrease in the body weight whereas the liver showed marginal increase in weight throughout the experimental period. Phosphatases and dehydrogenases were analyzed biochemically. Acid phosphatase, glucose-6-phosphatase and adenosine triphosphatase registered fall in contrast to alkaline phosphatase, SDH and LDH, all of which showed a definite increase. Lipids, nucleic acids and proteins, estimated biochemically, gradually decreased throughout the experimental period in response to D2O feeding.

    2009-01-01

    Students enrolled in a dance kinesiology class were trained to administer a screening protocol on younger dancers in the same department. The dance kinesiology students gained experience assessing alignment and functional symmetry in their peers, and then recommended exercises for gaining awareness and developing balanced patterns of movement. This "low stakes" assessment created both dialogue and peer support centered on helping the screened dancers understand and effectively work with their individual capacities and limitations. The project was designed to contribute to a culture of wellness and education within the dance department.

    2011-04-01

    We developed a new process for enzymatically synthesized glycogen (ESG), which is equivalent in physicochemical properties to natural-source glycogen (NSG) except its resistant property to degradation by α-amylase in vitro. In this study the metabolic fates of orally administered ESG in rats were investigated by a single oral administration test and a 2 week ingestion test. The glycemic index of ESG was 79. After the 2 week ingestion of ESG, the cecal content and production of short chain fatty acids were significantly increased, the pH value of cecal content was lowered, and the counts of Bifidobacterium and Lactobacillus in feces were significantly increased. Additionally, plasma levels of triacylglycerol and total cholesterol were significantly reduced by ESG. In contrast, NSG did not affect these parameters at all. The results collectively suggest that around 20% of orally administered ESG was transferred to the cecum in the form of polymer and assimilated into short chain fatty acids by microbiota and the polymer affected lipid metabolism.

    1982-09-01

    (/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.

    1989-01-01

    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.

    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.

    2015-05-01

    This study investigated the human gastrointestinal uptake (f1) and subsequent whole-body retention of orally administered inorganic radioactive cobalt. Of eight adult volunteers aged between 24 and 68 years, seven were given solutions of (57)Co (T1/2 = 272 d) containing a stable cobalt carrier, and six were given carrier-free (58)Co (T1/2 = 71 d). The administered activities ranged between 25 and 103 kBq. The observed mean f1, based on 6 days accumulated urinary excretion sampling and whole-body counting, was 0.028 ± 0.0048 for carrier-free (58)Co, and 0.016 ± 0.0021 for carrier-associated (57)Co. These values were in reasonable agreement with values reported from previous studies involving a single intake of inorganic cobalt. The time pattern of the total retention (including residual cobalt in the GI tract) included a short-term component with a biological half-time of 0.71 ± 0.03 d (average ± 1 standard error of the mean for the two nuclides), an intermediate component with a mean half-time of 32 ± 8.5 d, and a long-term component (observed in two volunteers) with half-times ranging from 80 to 720 d for the two isotopes. From the present data we conclude that for the short-lived (57)Co and (58)Co, more than 95% of the internal absorbed dose was delivered within 7 days following oral intake, with a high individual variation influenced by the transit time of the unabsorbed cobalt through the gastro-intestinal tract.

    AIM: To assess the efficacy and safety of a balanced approach using midazolam in combination with propofol, administered by non-anesthesiologists, in a large series of diagnostic colonoscopies. METHODS: Consecutive patients undergoing diagnostic colonoscopy were sedated with a single dose of midazolam (0.05 mg/kg) and low-dose propofol (starter bolus of 0.5 mg/kg and repeated boluses of 10 to 20 mg). Induction time and deepest level of sedation, adverse and serious adverse events, as well as recovery times, were prospectively assessed. Cecal intubation and adenoma detection rates were also collected. RESULTS: Overall, 1593 eligible patients were included. The median dose of propofol administered was 70 mg (range: 40-120 mg), and the median dose of midazolam was 2.3 mg (range: 2-4 mg). Median induction time of sedation was 3 min (range: 1-4 min), and median recovery time was 23 min (range: 10-40 min). A moderate level of sedation was achieved in 1561 (98%) patients, whilst a deep sedation occurred in 32 (2%) cases. Transient oxygen desaturation requiring further oxygen supplementation occurred in 8 (0.46%; 95% CI: 0.2%-0.8%) patients. No serious adverse event was observed. Cecal intubation and adenoma detection rates were 93.5% and 23.4% (27.8% for male and 18.5% for female, subjects), respectively. CONCLUSION: A balanced sedation protocol provided a minimalization of the dose of propofol needed to target a moderate sedation for colonoscopy, resulting in a high safety profile for non-anesthesiologist propofol sedation.

    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 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.

    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.

    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.

    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.

    Hagler, James R; Machtley, Scott A

    2016-01-28

    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.

    Motivational interviewing (MI) was developed by Miller and Rollnick as an evidence-based counselling approach for use in supporting people with alcohol problems. Over the years the principles and spirit of MI have been reviewed and fine-tuned and the approach has been embraced by practitioners worldwide and across fields. Since 2001 a number of instruments have been designed to evaluate the fidelity of MI practice. For the purposes of this study, one such instrument is used to assess a self-administered motivational instrument, known as the SAMI, which takes the interviewer role. The SAMI is evaluated against the MITI 3.1.1, which is designed to assess the extent to which MI interventions perform on five global dimensions. These are evocation, collaboration, autonomy/support, direction and empathy. The SAMI was assembled based on the principles and spirit of MI, problem solving and goal-setting. The targeted behaviour changes were student learning styles and approaches to study. The SAMI was distributed, completed and submitted electronically via the university virtual learning environment. Thirty three mature students of a university which delivered online nursing programme were invited to complete the SAMI. Of these, 25 submitted completed transcripts. Transcripts of a sample of six completed SAMIs were assessed by a group of teachers and researchers with experience in the use and evaluation of MI, using five-point Likert scales to assess the SAMI on the five dimensions. Overall, an average score exceeding 4.5 was attained across the five dimensions. Conventionally, such a score is recognised as competency in MI. However, on one dimension (empathy), the rating was three. This current research confirms that global principles have been observed in the online delivery of MI using the SAMI to probe approaches to study. Copyright © 2013 Elsevier Ltd. All rights reserved.

  10. Behavioral effects of urotensin-II centrally administered in mice.

    Urotensin-II (U-II) receptors are widely distributed in the central nervous system. Intracerebroventricular (i.c.v.) injection of U-II causes hypertension and bradycardia and stimulates prolactin and thyrotropin secretion. However, the behavioral effects of centrally administered U-II have received little attention. In the present study, we tested the effects of i.c.v. injections of U-II on behavioral, metabolic, and endocrine responses in mice. Administration of graded doses of U-II (1-10,000 ng/mouse) provoked: (1) a dose-dependent reduction in the number of head dips in the hole-board test; (2) a dose-dependent reduction in the number of entries in the white chamber in the black-and-white compartment test, and in the number of entries in the central platform and open arms in the plus-maze test; and (3) a dose-dependent increase in the duration of immobility in the forced-swimming test and tail suspension test. Intracerebroventricular injection of U-II also caused an increase in: food intake at doses of 100 and 1,000 ng/mouse, water intake at doses of 100-10,000 ng/mouse, and horizontal locomotion activity at a dose of 10,000 ng/mouse. Whatever was the dose, the central administration of U-II had no effect on body temperature, nociception, apomorphine-induced penile erection and climbing behavior, and stress-induced plasma corticosterone level. Taken together, the present study demonstrates that the central injection of U-II at doses of 1-10,000 ng/mouse induces anxiogenic- and depressant-like effects in mouse. These data suggest that U-II may be involved in some aspects of psychiatric disorders.

    To evaluate the analgesic properties of transdermally administered fentanyl and IM administered buprenorphine in sheep undergoing unilateral tibial osteotomy. 20 mature sheep. Fentanyl patches (n = 15 sheep) or placebo patches (5 sheep) were applied 12 hours before sheep underwent general anesthesia and a unilateral tibial osteotomy. Buprenorphine was administered to the placebo group every 6 hours commencing at time of induction. Signs of pain were assessed every 12 hours after surgery by 2 independent observers unaware of treatment groups. There were no differences in preoperative and intraoperative physiologic data between the 2 groups. Sheep treated with fentanyl required less preoperative administration of diazepam for sedation and had significantly lower postoperative pain scores, compared with those treated with buprenorphine. No complications associated with the antebrachium at the site of patch application were detected. Under the conditions of this study, transdermally administered fentanyl was a superior option to IM administered buprenorphine for alleviation of postoperative orthopedic pain in sheep. This information can be used to assist clinicians in the development of a rational analgesic regimen for research and clinical patients.

    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

    Science.gov (United States)

    Best, Carolyn

    2017-07-05

    Rationale and key points Nasogastric tube feeding is a method of enteral feeding commonly administered by nurses. Feed can be administered either using a volumetric enteral feeding pump (pump feeding) or via an enteral syringe (bolus feeding). This article explains how nurses can safely undertake these two methods of nasogastric tube feed administration at the patient's bedside. » Nasogastric tube feeding can be used to provide some or all of the patient's nutrition, fluid or medication. » Nurses should be equipped with the relevant knowledge to flush a nasogastric tube before the administration of feed or medication; set up and administer an enteral feed via a volumetric enteral feeding pump; and set up and administer a feed using a bolus method. » The position of the distal tip of the nasogastric tube must be confirmed as sitting in the patient's stomach before the tube is used to administer enteral feed, fluid or medication. Reflective activity 'How to' articles can help you update your practice and ensure it remains evidence-based. Apply this article to your practice. Reflect on and write a short account of: 1. How you think this article will change your practice when setting up and administering an enteral feed via a nasogastric tube. 2. How you could use this resource to educate your colleagues about nasogastric tube feeding via an enteral feeding pump or bolus feeding.

    1988-01-01

    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

    1986-01-01

    Three-fourths of all thorotrast-administered cases in Japan was warwounded ex-servicemen and their dates of thorotrast injections were concentrated between 1932 and 1945. An epidemiological follow-up study on 147 thorotrast-administered warwounded ex-servicemen whose protocols, contained records of thorotrast-administration, were kept at four former military hospitals, was initiated in 1963. At the end of 1983 the total number of their protocols discovered has increased to 282. On December 31, 1983, the authors found 50 malignant hepatic tumors, 25 other malignant tumors, 16 liver cirrhosis, and 4 blood diseases in 261 intravascularly thorotrast-administered cases. In the remaining 21 cases who had been given thorotrast by the route other than intravascularly, no significant difference was observed in the incidence of any diseases when compared with the controls. In 270 throtrast-administered autopsy cases reported during 1945-1983, 267 had been injected with thorotrast intravascularly and the remaining 3 had been given by other routes. Of the 267 intravascularly thorotrast-administered autopsy cases, 180 were malignant hepatic tumors, 20 liver cirrhosis, 16 leukemias, 5 aplastic anemias, 5 lung cancers, 3 sarcomas of thorotrast injected site, 2 metholiomas, 1 hemangioendothelioma of the spleen, 1 malignant lymphoma, and 1 osteosarcoma. The dosimetry of 96 intravascularly thorotrast-administered autopsy cases was performed for an estimate of the absorbed dose of critical organs, such as the liver, spleen, and bone marrow.

  11. Self-Administered Nicotine Suppresses Body Weight Gain Independent of Food Intake in Male Rats

    Science.gov (United States)

    Rupprecht, Laura E.; Smith, Tracy T.; Donny, Eric C.

    2016-01-01

    Introduction: The action of nicotine to suppress body weight is often cited as a factor impacting smoking initiation and the failure to quit. Despite the weight-suppressant effects of nicotine, smokers and nonsmokers report equal daily caloric intake. The weight-suppressive effects of nicotine in animal models of smoking are poorly understood. Furthermore, the Food and Drug Administration has authority to implement a policy markedly reducing nicotine levels in cigarettes; such a reduction could reduce smoking behavior, but have detrimental effects on body weight. The aim of this investigation was to examine the effects of self-administered nicotine on body weight and food intake in rats. Methods: In Experiment 1, rats with ad libitum access to chow responded for intravenous infusions of nicotine (60 µg/kg/infusion) or saline in daily 1-hour sessions; body weight and 24-hour food intake were measured. Experiment 2 tested the effects of subcutaneous injections of nicotine on food intake. In Experiment 3, rats were food restricted and self-administered nicotine across a range of doses (3.75–60 µg/kg/infusion) while body weight was measured. In Experiment 4, rats self-administered 60 µg/kg/infusion nicotine before reduction to one of several doses (1.875–15 µg/kg/infusion) for 50 days. Results: Self-administered nicotine suppressed weight gain independent of food intake. In food restricted rats, self-administered nicotine dose-dependently suppressed body weight gain. In rats self-administering 60 µg/kg/infusion nicotine, dose reduction increased body weight. Conclusions: Self-administered nicotine, even at low doses, suppressed body independent of food intake; this may have important implications for nicotine reduction policy. Implications: The results of the present studies demonstrate that self-administered nicotine suppresses body weight independent of food intake in rats. Further, the present studies establish that self-administered nicotine suppresses

    Odontogenic infections are among the main types of disorders located in the cephalic extremity. The aim of this study was to determine the efficiency of empirically administered antibiotics on the bacterial strains identified at the infection sites. The study included 10 randomly selected patients with odontogenic cervical soft tissue infections, who received antibiotic treatment prescribed by the family doctor or the dentist. The bacterial flora involved in the development of the septic process, the type of antibiotic administered to the patient and the sensitivity of the identified bacterial flora to the administered antibiotic were determined. In the 10 selected patients, 14 bacterial strains were detected; 7 patients had a single bacterial strain, and 3 patients had two or three types of bacteria. Of the administered antibiotics, amoxicillin was the most widely used (33.3% of the cases), followed by amoxicillin with beta-lactamase inhibitors (25% of the cases). In half of the patients, there was no sensitivity of the bacteria detected in the septic focus to the empirically administered antibiotic, and in 10% of the cases, partial sensitivity was evidenced. Empirical administration of antibiotics without the association of surgery did not prove to be effective in the treatment of cervical infections of odontogenic origin.

    The aim of study was to quantitatively evaluate the effects of self-administered facial massage, which was done by hand or facial roller. In this study, the psychophysiological effects of facial massage were evaluated. The central nerves system and the autonomic nervous system were administered to evaluate physiological system. The central nerves system was assessed by Electroencephalogram (EEG). The autonomic nervous system were assessed by peripheral skin temperature(PST) and heart rate variability (HRV) with spectral analysis. In the spectral analysis of HRV, the high-frequency components (HF) were evaluated. State-Trait Anxiety Inventory (STAI), Profile of Mood Status (POMS) and subjective sensory amount with Visual Analog Scale (VAS) were administered to evaluate psychological status. These results suggest that kept brain activity and had strong effects on stress alleviation.

    Gnambs, Timo; Kaspar, Kai

    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.

    The Joint Commission on the Accreditation of Healthcare Organizations requires that hospitals have a planned approach to systematically collect data on processes related to the use, ordering, and administering of blood components. This study describes how a comprehensive blood-administering assessment program and the FOCUS-PDCA approach improved overall blood-administering practices. Nurses were trained to observe blood issuance, blood administering, and patient monitoring steps, and to audit patient's charts to measure compliance with blood-ordering procedures. The observations were recorded on a standardized scannable form, which allowed automatic entry of recorded data directly into a computer database. A total of 982 assessments were completed during the 51-month study period. Documentation of informed consent improved from 80 percent to 100 percent. Compliance with a California law that requires patients to receive information on the risks, benefits, and alternatives to transfusion rose from 30 percent to 100 percent. Physicians' compliance in specifying the rate of blood administration improved from 30 percent to 100 percent, and verification of information on the patient's identification band with the patient's self-identification rose from 50 percent to 100 percent. For all other blood-administering steps, compliance remained high throughout the study period. For the past 9 months, 100-percent compliance has been maintained for all transfusion processes, and during this period no mistransfusions or blood administration near-misses have been reported. The blood-administering assessment program described above has improved transfusion practice, reduced the number of near-miss events, and may have prevented mistransfusions.

  20. Comparing administered and market-based water allocation systems using an agent-based modeling approach

    Science.gov (United States)

    Zhao, J.; Cai, X.; Wang, Z.

    2009-12-01

    It also has been well recognized that market-based systems can have significant advantages over administered systems for water allocation. However there are not many successful water markets around the world yet and administered systems exist commonly in water allocation management practice. This paradox has been under discussion for decades and still calls for attention for both research and practice. This paper explores some insights for the paradox and tries to address why market systems have not been widely implemented for water allocation. Adopting the theory of agent-based system we develop a consistent analytical model to interpret both systems. First we derive some theorems based on the analytical model, with respect to the necessary conditions for economic efficiency of water allocation. Following that the agent-based model is used to illustrate the coherence and difference between administered and market-based systems. The two systems are compared from three aspects: 1) the driving forces acting on the system state, 2) system efficiency, and 3) equity. Regarding economic efficiency, penalty on the violation of water use permits (or rights) under an administered system can lead to system-wide economic efficiency, as well as being acceptable by some agents, which follows the theory of the so-call rational violation. Ideal equity will be realized if penalty equals incentive with an administered system and if transaction costs are zero with a market system. The performances of both agents and the over system are explained with an administered system and market system, respectively. The performances of agents are subject to different mechanisms of interactions between agents under the two systems. The system emergency (i.e., system benefit, equilibrium market price, etc), resulting from the performance at the agent level, reflects the different mechanism of the two systems, the “invisible hand” with the market system and administrative measures (penalty

    To compare the postoperative analgesic effects of intravenous (IV), intramuscular (IM), subcutaneous (SC) or oral transmucosal (OTM) buprenorphine administered to cats undergoing ovariohysterectomy. Randomized, prospective and blinded clinical trial. 100 female cats. Cats were assigned to receive 0.01 mg kg(-1) of buprenorphine administered by the IV, IM, SC or OTM route (n = 25/group). Buprenorphine was made up to 0.3 mL with 0.9% saline. DIVAS (0-100 mm) and simple descriptive scale (SDS) (from 0 to 4) pain and sedation scores were assigned to each cat before and 1, 2, 3, 4, 6, 8, 12 and 24 hours after ovariohysterectomy. Buprenorphine and carprofen were administered for rescue analgesia. Data were analyzed using anova and Fisher's exact test (p 0.05). There were no significant differences between groups for sedation scores at any time. SDS pain scores did not detect any differences between groups (p > 0.05). DIVAS pain scores after OTM administration were significantly higher than IV and IM administration at 1 hour and at 3, 4, 6, 8 and 12 hours, respectively (p buprenorphine required rescue analgesia, respectively. There was a significantly higher incidence of treatment failure in cats that received SC and OTM buprenorphine compared with cats that received IV and IM buprenorphine (p buprenorphine provided better postoperative analgesia than SC or OTM administration of the drug and these routes of administration should be preferred when buprenorphine is administered to cats.

    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. Treated horses increased their water intake, and developed metabolic alkalaemia, significantly increased plasma sodium concentrations and significantly decreased plasma potassium concentrations. Enterally administered NaHCO3 may be beneficial in buffering caecal acidosis. © 2013 EVJ Ltd.

    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

    The safety profile of afoxolaner (an isoxazoline molecule) when combined with milbemycin oxime (a macrocyclic lactone) was evaluated according to the regulatory requirements when administered six times orally in a soft chewable formulation at a dose of at least 1×, 3×, or 5× the maximum exposure dose in 8-week-old Beagle dogs. Thirty-two healthy puppies (16 males and 16 females) were enrolled and allocated randomly to one of four treatment groups. Three doses were administered at 28-day intervals (Days 0, 28, and 56), followed by three additional doses administered with 14-day intervals (Days 84, 98, and 112). The study ended on Day 126. Treatment groups were as follows: Group 1: untreated, sham-dosed control; Group 2: afoxolaner/milbemycin oxime chews administered at a dose of at least 5 and 1 mg/kg, respectively (1×); Group 3: afoxolaner/milbemycin oxime chews administered at a dose of at least 15 and 3 mg/kg, respectively (3); and Group 4: afoxolaner/milbemycin oxime chews administered at a dose of at least 25 and 5 mg/kg, respectively (5×). All dogs were examined for general health twice a day beginning on Day -14. Physical examinations, and blood collections for clinical pathology analysis and afoxolaner and milbemycin oxime plasma concentrations, were performed throughout the study. No afoxolaner/milbemycin oxime treatment-related changes were observed in growth, physical variables, clinical pathology variables, or tissues examined histologically. No clinically relevant or statistically significant health abnormalities related to the administration of afoxolaner/milbemycin oxime were observed. No signs of macrocyclic lactone sensitivity were observed at any time during the study. Vomiting and diarrhea were observed sporadically across all groups including the controls. Based upon the results of this study, afoxolaner/milbemycin oxime soft chewables were shown to be safe when administered repeatedly at up to 5× the maximum exposure dose in dogs as

    To incorporate the assessment of vaccination status and administration of vaccines in an appointment-based model (ABM) and measure the impact on vaccinations administered and patient and pharmacist satisfaction with the appointment-based model. An ABM was implemented to systematically assess vaccination status and administer vaccines. Patients made an appointment to pick up synchronized prescriptions, and pharmacists assessed vaccination histories and administered vaccinations during the appointment. In addition, pharmacists could access the statewide immunization information system to objectively determine vaccination histories and document administered vaccines. This project was conducted at 24 Kroger Pharmacies in the Cincinnati-Dayton Area. Any patient filling more than 1 maintenance medication was eligible for the ABM program. Pharmacists were encouraged to target patients at high risk for medication problems and vaccine-preventable diseases, including patients 60 years of age or older with more than 5 medications and high-risk disease states such as diabetes, asthma, and chronic obstructive pulmonary disease. Pharmacies were randomized, and an a priori analysis was conducted to ensure that the 24 intervention and 78 control stores were similar at baseline. Postimplementation data on the mean number of vaccines per store were compared between the intervention stores and the control stores from September 2014 through December 2015. Patient and pharmacist satisfaction with the ABM was assessed via surveys. The pharmacist vaccine assessment as part of the ABM program showed higher overall mean vaccinations per store compared with the control group during the project period (1810.71 ± 500.88 vs. 1455.09 ± 754.43; P = 0.01). Patients and pharmacists felt that the ABM program facilitated vaccine discussions. The ABM program with a focus on vaccinations allowed pharmacists to systematically assess patient vaccination histories and administer vaccines in the

    Various potential immune-modulating microbially derived pathogen-associated molecular patterns (PAMP), or so called homotopes, are present in high concentrations in the environment of food animals. In previous studies, intravenously administered PAMP had variable effects on specific primary and secondary immune responses of poultry to systemically administered antigens. In the present study, we evaluated the effects of intratracheal (i.t.) challenge with the PAMP lipopolysaccharide, lipoteichoic acid (LTA), and Zymosan-A (containing 1,3 beta-glucan) on primary and secondary (total) antibody (Ab) responses and (isotype) IgM, IgG, and IgA responses to systemically administered human serum albumin (HuSA), and Ab titers to infectious bursal disease (Gumboro virus) and infectious bronchitis vaccines in layer hens at 9 and 22 wk of age. Birds were challenged via the trachea with PAMP for 5 consecutive days prior to primary and secondary immunization with HuSA. Intratracheally administered LTA and, to a minor extent, lipopolysaccharide significantly enhanced secondary total and IgG Ab responses to HuSA. 1,3 beta-Glucan did not significantly affect Ab responses to HuSA. All birds challenged with PAMP showed a decreased BW. Higher total Ab titers to infectious bursal disease and infectious bronchitis were found in birds challenged with LTA. The present results indicate that i.t. administered PAMP affect the humoral immune responsiveness of poultry, which may lead to an enhanced status of immune reactivity. Furthermore, our results suggest that the hygienic status of the environment influences BW (gain). The consequences of immune modulation by airborne PAMP or hygienic conditions in chicken husbandry for vaccine delivery and immune responsiveness of poultry are discussed.

    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.

    The safety profile of afoxolaner, a new isoxazoline molecule, was evaluated following the regulatory requirements when administered six times orally in a soft chewable formulation at a dose of at least 1×, 3× or 5× the maximum exposure dose (6.3mg/kg) in 8-week-old Beagle dogs. Thirty-two healthy puppies (16 males and 16 females) were enrolled and allocated randomly to one of four treatment groups. Treatments were administered at three, one-month dose intervals (Days 0, 28 and 56) followed by three, 2-week dose intervals (Days 84, 98 and 112). The study ended at Day 126. The groups were: Group 1: non-treated control; Group 2: afoxolaner chews administered at a dosage of at least 6.3mg/kg (1×); Group 3: afoxolaner chews administered at a dosage of at least 18.9 mg/kg (3×); and Group 4: afoxolaner chews administered at a dosage of at least 31.5mg/kg (5×). All dogs were examined for general health twice a day beginning on at least Day-14. Physical examinations, and blood collections for clinical pathology analysis and afoxolaner plasma concentrations, were performed throughout the study. On Day 126, 2 weeks following the last treatment, all dogs were humanely euthanized prior to the conduction of a full necropsy with tissue collection. No afoxolaner-related changes were observed in growth, physical variables, clinical pathology variables, or tissues examined histologically. No clinically or statistically significant health abnormalities related to the administration of afoxolaner were observed. Vomiting and diarrhea were observed sporadically across all groups including the controls. The kinetics of afoxolaner plasma concentrations was linear following 6 doses of 6.3, 18.9 and 31.5mg/kg and dose proportionality was demonstrated. There were no statistical differences (pafoxolaner was shown to be safe when administered repeatedly in a soft chewable formulation at up to 5× the maximum exposure dose in dogs as young as 8 weeks of age.

    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...

    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.

    The aim of this randomised, observer-blinded, crossover study was to compare the effects of four treatments, administered intravenously to six horses: saline and saline; 10 µg/kg detomidine and 7.5 µg/kg buprenorphine; 20 µg/kg detomidine and 7.5 µg/kg buprenorphine; and 20 µg/kg detomidine and 10 µg/kg buprenorphine. 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 (Pbuprenorphine (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.

    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

    1989-10-01

    Glucagon (0.01 microgram) administered through the intracerebroventricular route in anaesthetised mongrel dogs, caused a significant rise in blood glucose and a fall in liver glycogen (P less than 0.01). Concurrently, it increased the liver phosphorylase, glutamic oxaloacetic transaminase, glutamic pyruvic transminase and lipase activities by 30 min. Identical changes were observed in vagotomised animals. In pancreatectomised animals as well as in spinal cord transectomised animals, glucagon did not cause these changes. The study indicated that the hyperglycaemia produced by the centrally administered glucagon, is possibly a result of liver glycogenolysis and gluconeogenesis induced by endogenous glucagon secreted from the pancreas, the stimulus for which is the hypothalamo-pancreatic fibres responding to glucagon sensitive neurones in the hypothalamus.

    Fabry-associated pain may be the first symptom of Fabry disease (FD) and presents with a unique phenotype including mostly acral burning triggerable pain attacks, evoked pain, pain crises, and permanent pain. We recently developed and validated the first Fabry Pain Questionnaire (FPQ) for adult patients. Here we report on the validation of the self-administered version of the FPQ that no longer requires a face-to-face interview but can be filled in by the patients themselves allowing more flexible data collection. At our Würzburg Fabry Center for Interdisciplinary Treatment, Germany, we have developed the self-administered version of the FPQ by adapting the questionnaire to a self-report version. To do this, consecutive Fabry patients with current or past pain history (n = 56) were first interviewed face-to-face. Two weeks later patients' self-reported questionnaire results were collected by mail (n = 55). We validated the self-administered version of the FPQ by assessing the inter-rater reliability agreement of scores obtained by supervised administration and self-administration of the FPQ. The FPQ contains 15 questions on the different pain phenotypes, on pain development during life with and without therapy, and on impairment due to pain. Statistical analysis showed that the majority of questions were answered in high agreement in both sessions with a mean AC1-statistic of 0.857 for 55 nominal-scaled items and a mean ICC of 0.587 for 9 scores. This self-administered version of the first pain questionnaire for adult Fabry patients is a useful tool to assess Fabry-associated pain without a time-consuming face-to-face interview but via a self-reporting survey allowing more flexible usage.

    Nonresectable mast cell tumors (MCT) in dogs remain a therapeutic challenge, and investigation of novel combination therapies is warranted. Intermittent administration of tyrosine kinase inhibitors (TKI) combined with cytotoxic chemotherapy may effectively chemosensitize canine MCT while decreasing cost and adverse effects associated with either agent administered as monotherapy. The primary study objectives were to (1) identify the maximally tolerated dose (MTD), (2) determine the objective response rate (ORR) and (3) describe the adverse event profile of pulse-administered toceranib phosphate (TOC) combined with lomustine. Forty-seven client-owned dogs with measurable MCT. Toceranib phosphate was given PO on days 1, 3 and 5 of a 21-day cycle at a target dosage of 2.75 mg/kg. Lomustine was given PO on day 3 of each cycle at a starting dosage of 50 mg/m(2) . All dogs were concurrently treated with diphenhydramine, omeprazole, and prednisone. The MTD of lomustine was established at 50 mg/m(2) when combined with pulse-administered TOC; the dose-limiting toxicity was neutropenia. Forty-one dogs treated at the MTD were evaluable for outcome assessment. The ORR was 46% (4 complete response, 15 partial response) and the overall median progression-free survival (PFS) was 53 days (1 to >752 days). On multivariate analysis, variables significantly associated with improved PFS included response to treatment, absence of metastasis, and no previous chemotherapy. Combined treatment with pulse-administered TOC and lomustine generally is well tolerated and may be a reasonable treatment option for dogs with unresectable or metastatic MCT.

    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

    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 .

    Clinicians, researchers and politicians are seeking to better assess caregiver's needs. Challenges exist in broadly implementing this so as to provide appropriate support. The aim of this review was to compile self-administered instruments for assessment of caregiver's needs that are deemed to be scientifically robust. The Medline database was searched for publications reporting self-administered instruments assessing caregiver's needs with acceptable psychometric properties. These instruments were analyzed in terms of the development context, target population, concept, purpose, structure, content and psychometric properties. The dimensions of the needs were listed and categorized. A total of nine self-administered instruments were analyzed. They averaged 32 items, they were specifically developed for a targeted subpopulation of caregivers and dedicated to epidemiological research. Response devices were based on Likert scales. The main dimensions of the needs identified were 'Health and Care', 'Psychological - Emotional Support', 'Information-Knowledge', 'Social Life-Work-Finance'. None was specifically geared toward caregivers for the elderly, children or teenagers. In the absence of transcultural validation, no instrument was directly usable in Europe. Assessing caregivers' needs is a key part in providing caregivers with appropriate support. The development of self-administered instruments constitutes a complex field that is still underexplored at the international level; strict specifications with psychometric validation are essential. To be efficient, the instrument should be integrated in a larger process including: upstream, recognition, identification and assessment of the overall situation of the caregiver; and downstream, guidance, establishment and follow-up of a suitable action plan. © The Author 2017.

    This study was initiated to investigate uptake, distribution, and excretion of cadmium after prolonged intravenous and oral administrations. In both the intravenous and the oral studies cadmium was administered at 48 hr intervals for 30, 60, and 90 days to the first, second, and third animal groups, respectively. The total cadmium administered to each rat equaled 1 / 10 of the acute LD 50 (the intravenous LD 50 = 2.0 mg/kg, and the oral LD 50 = 150 mg/kg). In the excretion groups, urine and feces were collected every 48 hr during the experiment. All tissues and excreta were assayed for cadmium-109 activity by internal liquid scintillation counting. In the intravenous study the liver showed the highest cadmium retention. There were no significant differences between the mean retention values for liver in the intravenous study. Renal cadmium levels in the 120-day group were significantly higher than that of any of the other groups. In the oral study, the liver showed a mean retention of 0.90 percent on day 30, 0.96 percent on day 60, 0.68 percent on day 90, and 0.61 percent on day 120. The kidneys retained 0.13 percent, 0.19 percent, and 0.20 percent for the 30-day, 60-day, 90-day, and 120-day groups, respectively. In both the intravenous and the oral studies hepatic and renal cadmium levels were highly correlated. Cadmium excretion during the first three months of the intravenous study was cyclic in nature. After three months, about 22 percent of the total amount of intravenously administered cadmium had been excreted. In the oral study, almost all the administered cadmium was excreted

    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 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.)

    Full Text Available We compared the kinetic behaviour of tylosin administered to beehives by dusting or paper-pack placement through three treatment protocols (D, PP, CONTROL. D (dusting: tylosin, divided in four portions, was sprinkled over the ends of the hives' top bars weekly for four weeks (n=3; PP (paper-pack placement: tylosin in paper packs was administered at two-week intervals (n=3; CONTROL (control: the hives were left untreated (n=3. In every inspection, from each of the nine hives, fifty young (2-day-old larvae were sampled for drug analysis. The concentration of tylosin in the young larvae was determined by a microbiological assay with Geobacillus stearothermophilus ATCC 12980 as test organism. The (mean±SD maximum concentration (Cmax for D was 136.0±194.0 and for PP – 144.0±187.4 µg/mL; the time to reach Cmax (tmax was 1.5±0.9 h for D and 1.8 ± 1.8 h for PP. The area under the tylosin behaviour kinetics curve between 0–1392 h with D was 308.7±185.2 and with PP: 326.4±141.0 µg/h/mL, indicating no statistical difference between the treatments (P>0.05. The shorter duration of paper-pack-administered tylosin observed in the larvae implied a lower risk of antibiotic residues in the resulting honey

    Background and Aims Given the limitations of conventional therapies and restrictions imposed on newer pharmacological agents, there is an urgent need to develop efficacious and efficient treatments that teach patients behavioral self management skills for relieving irritable bowel syndrome (IBS) symptoms and associated problems. Method 75 Rome II diagnosed IBS patients (86% female) without comorbid GI disease were recruited from local physicians and the community and randomized to either 2 versions of cognitive behavior therapy (10 session, therapist administered CBT vs. 4 session, patient administered CBT) or a wait list comparison (WLC) that controlled for threats to internal validity Final assessment occurred two weeks after the 10 week treatment phase ends. Outcome measures included adequate relief from pain and bowel symptoms; global improvement of IBS symptoms (CGI-Improvement Scale); IBS symptom severity (IBS SSS); quality of life (IBSQOL); psychological distress (Brief Symptom Inventory); patient satisfaction (Client Satisfaction Scale). Results At week 12, both CBT versions were significantly (p < .0001) superior to WLC in the percentage of participants reporting adequate relief (e.g., MC-CBT = 72%, S-CBT = 60.9%, WLC = 7.4%) and improvement of symptoms. CBT treated patients reported significantly improved quality of life and IBS symptom severity but not psychological distress than WL patients (p < .0001) Conclusions Data from this pilot study lend preliminary empirical support to a brief patient administered CBT regimen capable of providing short term relief from IBS symptoms largely unresponsive to conventional therapies.

    Epidemiological data indicate that rates of methamphetamine misuse surpass those of d-amphetamine, but self-administration research in animals and humans has not typically demonstrated differences in their reinforcing effects. The present study used a within-session, exponentially-increasing progressive-ratio schedule and extended-access conditions to assess the relative reinforcing strength of d-amphetamine and methamphetamine in rhesus monkeys (n=5) trained to self-administer cocaine. A range of doses of methamphetamine (0.003–0.1 mg/kg/injection), d-amphetamine (0.003–0.1 mg/kg/injection) and cocaine (0.003–0.3 mg/kg/injection) was tested to capture the ascending and descending limbs of the dose-effect functions. Each drug functioned as a reinforcer, but the peak number of self-administered d-amphetamine injections was significantly lower compared to methamphetamine and cocaine; the peak number of self-administered injections of cocaine and methamphetamine did not differ. Although differences in availability and other social factors likely impact relative rates of abuse, the present data suggest that the greater reinforcing strength of methamphetamine contributes to its increased use compared to d-amphetamine.

    To assess the fiscal and logistical viability of school-based, pharmacist-administered influenza vaccination programs. Econometric observational study. Nine schools in the Rincon Unified School District, Santa Rosa, CA. Safeway Pharmacies; Rincon Unified School District; California Department of Public Health, Immunization Branch; and University of California, San Diego. Assessment of direct workflow observations and administrative data. Unit costs, productivity, and effectiveness of school-based, pharmacist-administered influenza vaccination programs. The results showed a unit cost of $23.63 (compared with $25.60 for mass vaccination and $39.79 for walk-in shot-only vaccination clinics). The productivity index ($0.88) and efficiency index ($1.12) were better compared with data reported for comparable vaccination programs. School-based, pharmacist-administered vaccination programs are fiscally and logistically self-sustaining, viable alternatives to medical office-based or community-based mass vaccination clinics, and may offer a practical strategy for vaccinating children and adolescents.

    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.

    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.

    Aphasia is a chronic condition that usually requires long-term rehabilitation. However, even if many effective treatments can be offered to patients and families, speech therapy services for individuals with aphasia often remain limited because of logistical and financial considerations, especially more than 6 months after stroke. Therefore, the need to develop tools to maximize rehabilitation potential is unquestionable. The aim of this study was to test the efficacy of a self-administered treatment delivered with a smart tablet to improve written verb naming skills in CP, a 63-year-old woman with chronic aphasia. An ABA multiple baseline design was used to compare CP's performance in verb naming on three equivalent lists of stimuli trained with a hierarchy of cues, trained with no cues, and not trained. Results suggest that graphemic cueing therapy, done four times a week for 3 weeks, led to better written verb naming compared to baseline and to the untrained list. Moreover, generalization of the effects of treatment was observed in verb production, assessed with a noun-to-verb production task. Results of this study suggest that self-administered training with a smart tablet is effective in improving naming skills in chronic aphasia. Future studies are needed to confirm the effectiveness of new technologies in self-administered treatment of acquired language deficits.

    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 Investigate the changes that occur in the placenta tissues of pregnant rats that were administered acrylamide (AA and vitamin E as a protective agent during pregnancy. Thirty rats that were proven positive for pregnancy with vaginal smear test were randomly distributed into control, corn oil, vitamin E, acrylamide and vitamin E + acrylamide groups. Pregnant rats were decapitated on the 20th day of the experiment. Malondialdehyde (MDA, reduced glutathione (GSH, total antioxidant capacity (TAS, total oxidant capacity (TOS and Xanthine oxidase (XO levels were measured in placenta tissues. It was determined that acrylamide application during pregnancy statistically significantly increased MDA, TOS and XO levels and reduced GSH and TAS levels in the placenta tissue of pregnant rats when compared to all other groups, and GAS and TAS levels statistically significantly increased in vitamin E administered group when compared to all other groups and TOS and XO levels were decreased to control group levels. It was observed that orally administered AA changed the antioxidant / oxidant equilibrium favoring the oxidants by increasing MDA, XO and TOS levels in pregnant rats and caused oxidative stress, while vitamin E administration returned the antioxidant / oxidant equilibrium back to normal levels, preventing oxidative stress induced toxicity.

    The aim of this study was to establish a method for determining administered activities for (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 (68)Ga-DOTATATE, (68)Ga-DOTATOC and (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  (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 (68)Ga-labelled peptides are class "B" radiopharmaceuticals. The baseline activity for all compounds is 12.8 MBq. In analogy to (18)F-fluoride, we recommend a minimum activity of 14 MBq. For paediatric nuclear medicine applications involving (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.

    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.

    Orally administered probiotics change gut microbiota composition and enzyme activities. Thus, coadministration of probiotics with drugs may lead to changes in the pharmacokinetic parameters of the drugs. In this study, we investigated the pharmacokinetics of acetaminophen in mice treated with probiotics. Oral administration of probiotics changed the gut microbiota composition in the mice. Of these probiotics, Lactobacillus reuteri K8 increased the numbers of clostridia, bifidobacteria, and enterococci, and Lactobacillus rhamnosus K9 decreased the number of bifidobacteria, determined by culturing in selective media. Next, we performed a pharmacokinetic study of acetaminophen in mice orally treated with K8 and K9 for 3 days. Treatment with K8 reduced the area under the curve (AUC) of orally administered acetaminophen to 68.4% compared with normal control mice, whereas K9 did not affect the AUC of acetaminophen. Oral administration to mice of K8, which degraded acetaminophen, increased the degradation of acetaminophen by gut microbiota, whereas K9 treatment did not affect it. Treatment with K8 increased the number of L. reuteri adhered in the upper small intestine, whereas the number of L. rhamnosus was not affected by treatment with K8 or K9. K8 increased the number of cyanobacteria, whereas K9 increased the number of deferribacteres. These results suggest that the intake of probiotics may make the absorption of orally administered drugs fluctuate through the disturbance of gut microbiota-mediated drug metabolism and that the subsequent impact on microbiota metabolism could result in altered systemic concentrations of the intact drug.

    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

    Background: Among different categories of sedative agents, benzodiazepines have been prescribed for more than three decades to patients of all ages. The effective and predictable sedative and amnestic effects of benzodiazepines support their use in pediatric patients. Midazolam is one of the most extensively used benzodiazepines in this age group. Oral form of drug is the best accepted route of administration in children. Objectives: The purpose of this study was to compare the efficacy and safety of a commercially midazolam syrup versus orally administered IV midazolam in uncooperative dental patients. Second objective was to determine whether differences concerning sedation success can be explained by child‘s behavioral problems and dental fear. Patients and Methods: Eighty eight uncooperative dental patients (Frankl Scales 1,2) aged 3 to 6 years, and ASA I participated in this double blind, parallel randomized, controlled clinical trial. Midazolam was administered in a dose of 0.5 mg/kg for children under the age 5 and 0.2 mg/kg in patients over 5 years of age. Physiologic parameters including heart rate, respiratory rate, oxygen saturation and blood pressure were recorded. Behavior assessment was conducted throughout the course of treatment using Houpt Sedation Rating Scale and at critical moments of treatment (injection and cavity preparation) by North Carolina Scale. Dental fear and behavioral problems were evaluated using Child Fear Schedule Survey-Dental Subscale (CFSS-DS), and Strength and Difficulties Questionnaire (SDQ). Independent t-test, Chi-Square, and Pearson correlation were used for statistical analysis. Results: Acceptable overall sedation ratings were observed in 90% and 86% of syrup and IV/Oral group respectively; Chi-Square P = 0.5. Other domains of Houpt Scale including: sleep, crying and movement were also not significantly different between groups. Physiological parameters remained in normal limits during study without significant

Naturally infected fish (1.5-year-old; K1-2 were divided into 6 groups. Three trial groups were administered praziquantel mixed in heat-treated amyloid vehicle (at doses of 50 mg kg-1 body weight. In 3 groups of control, the fish were administered amyloid vehicle only. Fish were examined using gut dissection 2, 4 and 6 days after the administration. The location, intensity and prevalence of individual species of tapeworms were recorded. A. huronensis and K. sinensis were found in the gut of carp together. A. huronensis was situated in the oesophageal part of foregut, and K. sinensis came after – immediately before the first intestine loop, of the intestines of carp. The invasion of A. huronensis was fully eliminated in all trial groups after 4 days whereas some specimens of K. sinensis still persisted in the gut of few fish. The full elimination of both parasites was observed 6 days after administration. Our results showed that elimination of K. sinensis takes longer than elimination of A. huronensis. The dose of 50 mg kg-1 of orally administered praziquantel is effectual to control A. huronensis and K. sinensis infections in common carp successfully, however, a significant decrease of the number of parasites was also caused by a single oral administration of big bolus vehicle and leaving unfed fish in the clean water.

    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.

    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 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.

    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.

    Cisplatin, known as an anticancer drug, has been widely used; however, diverse disadvantageous side effects, including appetite loss, afflict patients. Nesfatin-1/NucB2, discovered as an anorexic neuropeptide, is broadly expressed in the central nervous system (CNS) and peripheral organ. In the present study, we examined the effects of intraperitoneally (i.p.) administered cisplatin on central nesfatin-1/NucB2. Saline, as control, or cisplatin (6 mg/kg dissolved in saline) was i.p. administered in adult male Wistar rats (180-220 g). Cumulative food intake was remarkably suppressed for at least 24 h and body weight was significantly smaller at 24 h after i.p. administration of cisplatin compared to control group. At 90 min after i.p. administration, they were perfused, followed by carrying out double-immunohistochemistry for Fos and nesfatin-1/NucB2. The percentage of nesfatin-1/NucB2 immunoreactive neurons expressing Fos was marked increased in the hypothalamus and brainstem after i.p. administration of cisplatin. Intracerebroventricularlly administered nesfatin-1/NucB2-antisense resulted in a significant attenuation of decreased food intake for 2 h after i.p. administration of cisplatin compared to nesfatin-1/NucB2-missense treated group. These results suggest that i.p. administration of cisplatin activated, at least in part, nesfatin-1/NucB2 neuron in the CNS and may exert anorexigenic effects in rats. Copyright © 2017 Elsevier Inc.

    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

    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

    2016-06-01

    On the basis of these results, it can be concluded that caffeine in high doses disturbs the development of bone tissue. An additional factor which enhances the adverse effects of this substance on bone tissue is the temperature of the administered solution (10°C. In the Experimental Group, a significant decrease in the calcium level, as well as an increase in the potassium level, was observed. The X-ray microprobe can be a perfect complement to the methods which enable determination of the mineralization of osseous tissue.

    Full Text Available Abstract Background Anaesthetic pre-registration house officer posts have been available since 1997. With the change to postgraduate medical training introduced in 2005, these posts have become vital building blocks for Foundation Programmes. Discussion We debate the skills that new Foundation Programme doctors in such posts should be taught, particularly whether administration of an anaesthetic holds an important place. The opinion of college tutors prior to the institution of the foundation programme is included. These were obtained from a postal questionnaire. Summary We maintain that teaching how to administer an anaesthetic remains an important learning objective and something that should be actively pursued.

    This research examined bedside medication verification administration in 2 adult critical care units, using portable computers and permanent bedside computers. There were no differences in the number of near-miss errors, the time to administer the medications, or nurse perception of ease of medication administration, care of patients, or reliability of technology. The percentage of medications scanned was significantly higher with the use of permanent bedside computers, and nurses using permanent bedside computers were more likely to agree that the computer was always available.

    The December 2014 issue of the European Journal of Oncology Nursing published an article by Näppä, Rasmussen, Axelsson, and Lindqvist that reported on a qualitative study of the challenges experienced by Swedish nurses when administering palliative cancer treatment at the end of life. The study identified the various clinical scenarios that create dilemmas among nurses. The authors described why chemotherapy at the end of life has become so prevalent and offered strategies to minimize or prevent the moral distress that can occur. Research from the United States identified similar trends in end-of-life treatment and supportive recommendations for multidisciplinary palliative care team collaboration as a solution.

    2012-08-01

    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.

    The biological response modifier, S-TDM, administered in doses of 100, 200, 400 and 800 ug/mouse 24 hours before a LD80/30 dose (5.6 Gy at 0.4 Gy-MLT/minute) of radiation (neutron:gamma double-bond 1) resulted in survival of 100%, 60%, 89% and 20% respectively. Because of the radioprotective efficacy of this immunomodulator, the behavioral effects of S-TDM were investigated. Locomotor activity, food intake, water consumption, and body weight were examined using female B6D2F1 mice. At doses of 100-400 ug/mouse locomotor activity decreased within 4 hours of administration and returned to control values by 2.5 days postinjection. Food and water intake were significantly depressed at doses of 100, 200, and 400 ug/mouse on the day following drug administration and recovered in 1 day. Body weight was significantly decreased in the 100 and 200 ug/mouse groups for 2 days and in the 400 ug/mouse for 3 days following injection of S-TDM. These results indicate that there is short-term reversible toxicity in mice administered S-TDM at doses of 100, 200, and 400 ug/mouse

    Full Text Available ABSTRACT: This study compared the effects of enteral electrolyte solutions with different osmolarities in Holstein cattle. Eighteen newborn calves were evenly divided into three groups and administered the following treatments: hypotonic electrolyte solution (ESHYPO containing 4g NaCl, 0.5g KCl, 1g sodium acetate, and 7.5g dextrose diluted in 1,000mL water; isotonic electrolyte solution (ESISO containing 5g NaCl, 1g KCl, 2g sodium acetate, and 10g dextrose diluted in 1,000mL water; and hypertonic electrolyte solution (ESHYPER containing 6g NaCl, 1g KCl, 3g sodium acetate, and 15g dextrose diluted in 1,000mL water. Solutions were administered at a rate of 15mL kg-1hr-1 for 12 hours in a continuous flow. All three solutions increased the concentration of plasma sodium, but ESHYPO did not alter the serum osmolarity. Both ESISO and ESHYPO resulted in an increase in volemia.

  3. Pharmacokinetics of the Antiviral Lectin Griffithsin Administered by Different Routes Indicates Multiple Potential Uses

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Griffithsin (GRFT is a red alga-derived lectin with demonstrated broad spectrum antiviral activity against enveloped viruses, including severe acute respiratory syndrome–Coronavirus (SARS-CoV, Japanese encephalitis virus (JEV, hepatitis C virus (HCV, and herpes simplex virus-2 (HSV-2. However, its pharmacokinetic profile remains largely undefined. Here, Sprague Dawley rats were administered a single dose of GRFT at 10 or 20 mg/kg by intravenous, oral, and subcutaneous routes, respectively, and serum GRFT levels were measured at select time points. In addition, the potential for systemic accumulation after oral dosing was assessed in rats after 10 daily treatments with GRFT (20 or 40 mg/kg. We found that parenterally-administered GRFT in rats displayed a complex elimination profile, which varied according to administration routes. However, GRFT was not orally bioavailable, even after chronic treatment. Nonetheless, active GRFT capable of neutralizing HIV-Env pseudoviruses was detected in rat fecal extracts after chronic oral dosing. These findings support further evaluation of GRFT for pre-exposure prophylaxis against emerging epidemics for which specific therapeutics are not available, including systemic and enteric infections caused by susceptible enveloped viruses. In addition, GRFT should be considered for antiviral therapy and the prevention of rectal transmission of HIV-1 and other susceptible viruses.

    Azithromycin may be an alternative adjunctive systemic antibiotic in non-surgical periodontal therapy. This study aims to identify randomized controlled trials evaluating non-surgical periodontal treatment of chronic and/or aggressive periodontitis supplemented with systemically administered azithromycin. A systematic literature search was performed for publications published by 31 March 2014 using electronic databases and hand search. Randomized controlled trials published in English or German language, with a follow-up ≥6 months were included. From 231 titles identified, nine publications were eligible for inclusion. Among the studies included, showing some risk of bias, seven reported on patients with chronic periodontitis and two with aggressive periodontitis. Minor adverse events were described in five studies. A synthesis of results using a vote counting method was applied. Significant (p azithromycin were shown in six studies for probing depth changes and in five studies for clinical attachment level changes. In contrast to aggressive periodontitis patients, data from this analysis indicate a potential benefit of systemic azithromycin as adjunctive to non-surgical periodontal therapy in chronic periodontitis patients. When contraindications for the standard antibiotics are present, azithromycin (AZM) may be considered as alternative systemically administered antibiotic drug in selected cases of chronic periodontitis.

  6. 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.

    We studied absorption, distribution, metabolism, and excretion of polyamines (putrescine, spermidine, and spermine) in the gastrointestinal tract using {sup 15}N-labeled polyamines as tracers and ionspray ionization mass spectrometry (IS-MS). The relatively simple protocol using rats bearing solid tumors provided useful information. Three {sup 15}N-labeled polyamines that were simultaneously administered were absorbed equally from gastrointestinal tract, and distributed within tissues at various concentrations. The uptake of {sup 15}N-spermidine seemed preferential to that of {sup 15}N-spermine since the concentrations of {sup 15}N-spermidine in the liver and tumors were higher, whereas those of {sup 15}N-spermine were higher in the kidney, probably due to the excretion of excess extracellular spermine. Most of the absorbed {sup 15}N-putrescine seemed to be lost, suggesting blood and tissue diamine oxidase degradation. Concentrations of {sup 15}N-spermidine and {sup 15}N-spermine in the tumor were low. We also describe the findings from two rats that were administered with {sup 15}N-spermine. The tissue concentrations of {sup 15}N-spermine were unusually high, and significant levels of {sup 15}N-spermidine were derived from {sup 15}N-spermine in these animals. (author)

  8. Maternally administered sustained-release naltrexone in rats affects offspring neurochemistry and behaviour in adulthood.

    Directory of Open Access Journals (Sweden)

    Waleed O Farid

    Full Text Available Naltrexone is not recommended during pregnancy. However, sustained-release naltrexone implant use in humans has resulted in cases of inadvertent foetal exposure. Here, we used clinically relevant dosing to examine the effects of maternally administered sustained-release naltrexone on the rat brain by examining offspring at birth and in adulthood. Maternal treatment (naltrexone or placebo implant started before conception and ceased during gestation, birth or weaning. Morphometry was assessed in offspring at birth and adulthood. Adult offspring were evaluated for differences in locomotor behaviour (basal and morphine-induced, 10 mg/kg, s.c. and opioid neurochemistry, propensity to self-administer morphine and cue-induced drug-seeking after abstinence. Blood analysis confirmed offspring exposure to naltrexone during gestation, birth and weaning. Naltrexone exposure increased litter size and reduced offspring birth-weight but did not alter brain morphometry. Compared to placebo, basal motor activity of naltrexone-exposed adult offspring was lower, yet they showed enhanced development of psychomotor sensitization to morphine. Developmental naltrexone exposure was associated with resistance to morphine-induced down-regulation of striatal preproenkephalin mRNA expression in adulthood. Adult offspring also exhibited greater operant responding for morphine and, in addition, cue-induced drug-seeking was enhanced. Collectively, these data show pronounced effects of developmental naltrexone exposure, some of which persist into adulthood, highlighting the need for follow up of humans that were exposed to naltrexone in utero.

    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 aim of this study was to determine the optimum administered activity to patients, of the DMSA-Tc-99m looking for good image quality in gamma camera and a best radiological protection for the patient. Three protocols and two activity values in each protocol were tested (71.2 MBq and 132.8 MBq) in six patients each. An observer blinded to the administered activity, graded the rear view of both kidneys in the 36 patients. The relation of the Rois in kidney/bladder and kidney/liver, and the labeling yield were the most important parameters in the construction of a discriminatory function of image quality (r=0.56, r=0.33 and r=0.461 respectively). The correlation between the observer's opinion and the prediction of the function was r=0.429. The function classified 91.7% of the cases correctly. The best results for the patient's radiological protection were obtained by using 71.2 MBq and 700 k Counts as stopped criterion. When the labeling yield was lower than 98% it was better to applied 132.8 MBq and to stop the scanning after 3 minutes to guarantee a best image quality. (author)

    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: 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

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

    Safety planning is a brief intervention that has become an accepted practice in many clinical settings to help prevent suicide. Even though it is quick compared to other approaches, it frequently requires 20 min or more to complete, which can impede adoption. A self-administered, Web-based safety planning application could potentially reduce clinician time, help promote standardization and quality, and provide enhanced ability to share the created plan. The aim of this study was to design, build, and test the usability of a Web-based, self-administered safety planning application. We employed a user-centered software design strategy led by a multidisciplinary team. The application was tested for usability with a target sample of suicidal patients. Detailed observations, structured usability ratings, and Think Aloud procedures were used. Suicidal ideation intensity and perceived ability to cope were assessed pre-post engagement with the Web application. A total of 30 participants were enrolled. Usability ratings were generally strong, and all patients successfully built a safety plan. However, the completeness of the safety plan varied. The mean number of steps completed was 5.5 (SD 0.9) out of 6, with 90% (27/30) of participants completing at least 5 steps and 67% (20/30) completing all 6 steps. Some safety planning steps were viewed as inapplicable to some individuals. Some confusion in instructions led to modifications to improve understandability of each step. Ratings of suicide intensity after completion of the application were significantly lower than preratings, pre: mean 5.11 (SD 2.9) versus post: mean 4.46 (SD 3.0), t 27 =2.49, P=.02. Ratings of ability to cope with suicidal thoughts after completion of the application were higher than preratings, with the difference approaching statistical significance, pre: mean 5.93 (SD 2.9), post: mean 6.64 (SD 2.4), t 27 =-2.03, P=.05.

    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

  17. How do patients with inflammatory bowel disease want their biological therapy administered?

    Allen, Patrick B

    2010-01-01

    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 combination DTaP-IPV/Hib vaccine was licensed in the United States in 2008 for children ages 6weeks through 4years with doses administered at 2, 4, 6, and 15-18months of age. The aim of this study was to assess the safety of DTaP-IPV/Hib vaccine routinely administered as part of clinical care to infants at Kaiser Permanente Northern California. This was an observational, retrospective study that included all 2-month-old infants vaccinated with either DTaP-IPV/Hib or another DTaP-containing vaccine. We monitored all subjects for non-elective hospitalizations, emergency department visits and selected outpatient outcomes (seizures, Guillain-Barré Syndrome, encephalopathy, encephalitis, alteration of consciousness, meningitis, hypersensitivity reactions, immune thrombocytopenic purpura, hemolytic anemia, type 1 diabetes, and Kawasaki disease) beginning with their first dose through 6months after a 4th dose or until 24months of age. We calculated incidence rate ratios (IRRs) in the primary analysis by comparing rates of outcomes during the post-vaccination risk interval with rates during a comparison interval more remote from vaccination. Secondary analyses compared outcomes after DTaP-IPV/Hib with those after other DTaP-containing vaccines. We reviewed the medical records of selected outcomes. From October 1, 2008 through July 31, 2010, 14,042 subjects received a first dose of DTaP-IPV/Hib, 13,194 received 2 doses, 12,548 received 3 doses and 6702 received 4 doses. Overall, there were 166 comparisons with significantly elevated IRRs and 165 comparisons with significantly reduced IRRs. Medical record review of outcomes with significantly elevated IRRs in both the primary and secondary analyses did not suggest any relationship with DTaP-IPV/Hib. This study did not detect any safety concerns following DTaP-IPV/Hib and provides reassurance that DTaP-IPV/Hib administered as part of routine care was not associated with unexpected safety risks.

    2018-02-27

    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

    Marcellus, Lenora

    2008-09-01

    A significant percentage of children in foster care in North America are younger than 1 year of age and are in foster care because of parental substance use and other social challenges. Infants might present with specific health and behavioral issues that are challenging to manage within the foster family home environment; foster families require specialized skills and knowledge to manage these issues. In this article, the author describes a constructivist grounded theory of the process of becoming and providing family foster caregiving in the context of caring for infants with prenatal alcohol and/or drug exposure. The basic social process of (ad)ministering love was identified. The author further describes the three phases of this process and the core concepts within each phase.

    Four significant groups are involved in the implementation of the CAAA. There is the federal EPA with authority to administer most of the provisions including allocating allowances and tracking them. The state air quality will play a role in implementing Phase II of the CAAA. The affected utilities have specific reporting requirements as well as emission limits. The economic regulators, state public utility commissions, and FERC are also involved in implementation. This section addresses the role of these agencies in CAAA implementation by outlining the main regulatory reporting relationships they have as described in EPA's proposed rules. In general, the federal EPA is the most directly involved regulatory agency, although ancillary roles exist for state commissions. State air quality of EPA will play a more direct role in CAAA administration in Phase II. 11 refs., 3 figs

    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

    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.

  7. 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.

    Directory of Open Access Journals (Sweden)

    Yuuki Nakamura

    Full Text Available Much discussion has surrounded the association between the administration of neuraminidase inhibitors (NI and severe abnormal behaviors, including sudden running away and jumping from a high place, which can be life-threatening if no one intervenes. Using data on the number of abnormal behaviors and patients who had been prescribed NI in Japan, we calculated the incidence rate of severe abnormal behaviors among influenza patients who had been prescribed NI. Then, we evaluated the relative risk between the four types of NI on severe abnormal behavior. We found no significant difference in the incidence rates of abnormal behavior by the type of NI. Results implicate that the current policy of package inserts, which warn physicians that patients who were administered ANY type of NI might exhibit abnormal behavior, seems to be appropriate.

    1978-01-01

    Cadmium binding protein was isolated by gel filtration from the supernatant fraction of the small intestines of rats continuously administered cadmium for 1, 3, 6, 9, 32 and 96 days. About two-thirds of the total amount of absorbed cadmium was associated with the cytosol of mucosal tissues scraped from the small intestines. Cadmium was almost always bound to proteins, molecular weights of which ranged from 5,400 to 9,800. Cadmium in livers and that in intestinal mucosa were in the same binding state, but as there was some lag period between the induction of the Cd-binding proteins of both tissues, the protein of the small intestinal mucosal cells must have been induced at the mucosa itself by contact with cadmium. The Cd-binding protein of the mucosal cells may play an important role in absorbing cadmium, because no other form of this metal was found in the mucosal cells of the small intestines.

    Postoperative pain management in laboratory animals is important for animal welfare and required under law in many countries. Frequent injection of analgesics to rodents after surgery is stressful for the animals and labour-intensive for animal care personnel. An alternative dosing scheme...... such as administration of analgesics in the drinking water would be desirable. However, the efficacy of a chronic oral analgesic treatment via this route has not yet been documented. This study investigated the antinociceptive efficacy of buprenorphine administered ad libitum via the drinking water of laboratory rats....... The antinociceptive efficacy of buprenorphine in drinking water was compared with repeated subcutaneous injections. A comparison was also made between buprenorphine in drinking water and the combination of one single subcutaneous injection of buprenorphine followed by buprenorphine in drinking water. Antinociception...

    Older adults' memory reports are often less complete and accurate than those by younger adults. The current study assessed the suitability of the Self-Administered Interview (SAI) as retrieval support for older eyewitnesses, and examines whether experience with the SAI leads to improved performance on subsequent events where the SAI is not used. Participants recalled an event with the SAI or free recall instructions. After 1 week, all participants watched a second event and freely recalled its content. SAI participants reported more correct details for the initial event, and a "transfer" of the initial recall advantage to the second event was observed.

    A study was undertaken to determine the degree of acute bone marrow and vital organs injury sustained when dogs were administered doses of 153Sm-EDTMP calculated to irradiate an acute bone lesion arising from cancer metastasis to a dose considered palliative or even therapeutic (20-160 Gy). The study revealed significant (p less than 0.05) temporary depression of the bone marrow in all doses in the therapeutic (greater than 40 Gy) range. Palliative (20 Gy) doses caused significant leukocyte depression but insignificant (p greater than 0.05) depression of platelet and packed cell volumes when compared to control animals. A mild transient rise in the levels of serum alkaline phosphatase occurred immediately following radioisotope administration. All hematologic parameters had returned to normal by six weeks after the last injection of radioisotope. The study indicates potential for this compound as a safe, therapeutic radiopharmaceutical for treatment of cancer bone metastasis

    The use of radiolabeled antibodies is one of the most effective strategies to diagnose and treat cancers. However, it is hindered by the relatively low delivery to tumors following intravenous administration, in particular, cancers in peritoneal cavity. Intraperitoneal administration of radiolabeled antibodies results in significantly higher exposure to the peritoneal cavity than does intravenous administration. Therefore, intraperitoneal administration of the radiolabeled antibodies can be more effective to diagnose and treat cancers in peritoneal cavity such as ovarian and colonic cancers. This study was performed to determine the biodistribution pattern of intraperitoneally-administered radiolabeled antibodies. The {sup 125}I-labeled IgG was rapidly absorbed into the blood and organs, and the radioactivities were dropped in 24 hr p.i. These results suggest that the intraperitoneal administration of the radiolabeled antibodies can be an effective way to treat diseases in the peritoneal cavity.

    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.

    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.

    Tedizolid, a novel oxazolidinone antibacterial, was administered to Long Evans rats by oral gavage once daily for up to 9 months at doses near the maximum tolerated dose (MTD) to evaluate for potential neurotoxicity. Mean plasma exposures of tedizolid at the low-, medium-, and high-dose levels (7.5, 15, and 30 mg/kg of body weight/day for males; 2.5, 5, and 10 mg/kg/day for females) were similar between males and females and were 1.8-, 3.9-, and 8.0-fold greater than exposures in patients at the therapeutic dose (200 mg once daily). Evaluated endpoints included survival, clinical observations, body weight, and food consumption. At 1, 3, 6, and 9 months, ophthalmic examinations, functional observational batteries, and locomotor activity measures were conducted, brain weights/sizes were recorded, and perfusion-fixed tissues were collected from 12 rats/sex/group/time point. A detailed morphological assessment was conducted on brain, eyes, optic nerve/tract, spinal cord, peripheral nerves (includes sciatic, sural, tibial, peroneal, trigeminal), and skeletal muscle. At the end of 9 months, less body weight gain was seen in high-dose males (-6.7%) and females (-5.8%) compared with that seen in controls. There were no tedizolid-related adverse neurobehavioral effects or tedizolid-related histopathologic changes in the central/peripheral nervous systems, including the optic nerve. Results of this study indicate that tedizolid was not neurotoxic when administered long term to pigmented rats at doses near the MTD, which were up to 8-fold higher than the human therapeutic exposure.

    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.

    Fucoidans extracted from brown algae have been documented to have excellent antithrombotic activity when administered by either intravenous or subcutaneous route in animal models. However, it is unknown if the fucoidans also have antithrombotic activity when administered orally, a highly desirable feature of oral antithrombotic agents. In the present study, we compared the oral absorption, bioavailability and antithrombotic activity of two fucoidan fractions from Laminaria japonica with different molecular weight by oral administration in an electricity induced arterial thrombosis model and the underlying molecular mechanisms. After a single dose of oral administration, the fucoidan content in plasma and urine in rats was assessed using the reverse-phased HPLC analysis of 1-phenyl-3-methyl-5-pyrazolone (PMP)-labeled fucose. The fucose content in the low molecular weight (LMW) fucoidan-treated rats increased up to 2-fold and peaked at 15h, indicating that the LMW fucoidan had much better absorption and bioavailability than the MMW fucoidan in vivo. Oral administration of the LMW fucoidan at 400 and 800mg/kg for 30days inhibited the arterial thrombosis formation effectively induced by electrical shock in rats, accompanied by moderate anticoagulation activity, regulation on TXB2 and 6-keto-PGF1α, significant antiplatelet activity and effective fibrinolysis. The LMW fucoidan showed better oral absorption and antithrombotic activity in addition to different antithrombotic mechanisms compared to those of the medium molecular weight (MMW) fucoidan. Thus, the LMW fucoidan has a potential to become an oral antithrombotic agent. Copyright © 2016. Published by Elsevier Ltd.

    The toxicity of antineoplastic drugs is well documented. Many are known or suspected human carcinogens where no safe exposure level exists. Authoritative guidelines developed by professional practice organizations and federal agencies for the safe handling of these hazardous drugs have been available for nearly three decades. As a means of evaluating the extent of use of primary prevention practices such as engineering, administrative and work practice controls, personal protective equipment (PPE), and barriers to using PPE, the National Institute for Safety and Health (NIOSH) conducted a web survey of health care workers in 2011. The study population primarily included members of professional practice organizations representing health care occupations which routinely use or come in contact with selected chemical agents. All respondents who indicated that they administered antineoplastic drugs in the past week were eligible to complete a hazard module addressing self-reported health and safety practices on this topic. Most (98%) of the 2069 respondents of this module were nurses. Working primarily in hospitals, outpatient care centers, and physician offices, respondents reported that they had collectively administered over 90 specific antineoplastic drugs in the past week, with carboplatin, cyclophosphamide, and paclitaxel the most common. Examples of activities which increase exposure risk, expressed as percent of respondents, included: failure to wear nonabsorbent gown with closed front and tight cuffs (42%); intravenous (I.V.) tubing primed with antineoplastic drug by respondent (6%) or by pharmacy (12%); potentially contaminated clothing taken home (12%); spill or leak of antineoplastic drug during administration (12%); failure to wear chemotherapy gloves (12%); and lack of hazard awareness training (4%). The most common reason for not wearing gloves or gowns was "skin exposure was minimal"; 4% of respondents, however, reported skin contact during handling and

    Respiratory therapists (RTs) and other health-care workers are potentially exposed to a variety of aerosolized medications. The National Institute for Occupational Safety and Health (NIOSH) Health and Safety Practices Survey of Healthcare Workers describes current exposure control practices and barriers to using personal protective equipment during administration of selected aerosolized medications. An anonymous, multi-module, web-based survey was conducted among members of health-care professional practice organizations representing RTs, nurses, and other health-care practitioners. A module on aerosolized medications included submodules for antibiotics (amikacin, colistin, and tobramycin), pentamidine, and ribavirin. The submodules on antibiotics, pentamidine, and ribavirin were completed by 321, 227, and 50 respondents, respectively, most of whom were RTs. The relatively low number of ribavirin respondents precluded meaningful interpretation of these data and may reflect the rare use of this drug. Consequently, analysis focused on pentamidine, classified by NIOSH as a hazardous drug, and the antibiotics amikacin, colistin, and tobramycin, which currently lack authoritative safe handling guidelines. Respondents who administered pentamidine were more likely to adhere to good work practices compared with those who administered the antibiotics. Examples included training received on safe handling procedures (75% vs 52%), availability of employer standard procedures (82% vs 55%), use of aerosol delivery devices equipped with an expiratory filter (96% vs 53%) or negative-pressure rooms (61% vs 20%), and always using respiratory protection (51% vs 13%). Despite the availability of safe handling guidelines for pentamidine, implementation was not universal, placing workers, co-workers, and even family members at risk of exposure. Although the antibiotics included in this study lack authoritative safe handling guidelines, prudence dictates that appropriate exposure

    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.

    2015-01-01

    Background The primary goal of this study was to establish a paradigm for credibly administering placebo alcohol to underage drinkers. We also sought to create a new, valid procedure for establishing placebo alcohol believability. Method Participants were 138 American college students (66.7% female) predominantly (90.0%) under the legal drinking age. Groups of 2–3 participants and one same-sex confederate consumed mixed drinks, purportedly containing alcohol, ad-lib in a naturalistic bar-laboratory for 20 minutes. All beverages, however, were non-alcoholic but we used visual, olfactory, and taste cues to maximize placebo credibility. Also, the confederate made two scripted statements designed to increase the perception of drinking real alcohol. After the drinking portion, participants responded to survey items related to alcohol consumption and intoxication. Next, they were individually debriefed, with open-ended responses used to make a determination of whether the participant was deceived with respect to placebo alcohol. Results All participants estimated consuming some amount of alcohol. However, using a more conservative criteria for estimating alcohol believability based on the debrief, 89.1% of participants were classified as deceived. Deceived participants were much more likely to estimate having a positive Blood Alcohol Content, and to say their current level of intoxication was typical given the amount of alcohol consumed than non-deceived participants. Discussion Credibly administering placebo alcohol to underage drinkers is possible. This approach carries great potential for future laboratory work. In addition, the methodology used here to classify participants as deceived or not deceived appears valid based on self-reported BAC estimation and intoxication levels. PMID:26334562

    Concern that asking about a specific behavior could elicit that behavior is often cited as a reason that communities and schools should not administer surveys about youth drug use. In this study, we investigated if this question-behavior effect exists related to substance use. We examined if simply asking a student about their current drug use leads to an increase in drug use 1 year later. This study tests the validity of the question-behavior effect on youth drug use in a longitudinal panel of 2,002 elementary school students. The sample of students was drawn from the Community Youth Development Study, a community-randomized test of the Communities That Care prevention system. If the prevalence of self-reported drug use in sixth grade in a sample surveyed in fifth and sixth grades was higher than in an accretion sample surveyed only in sixth grade, the difference could indicate a question-behavior effect. Results from logistic regression analyses did not provide any evidence of a question-behavior effect on 30-day or lifetime prevalence of alcohol, tobacco, inhalant, or marijuana use reported in sixth grade. Asking youth about drug use in a survey did not increase the rates of self-reported drug use measured 1 year later. The absence of evidence of a question-behavior effect should ease concerns of communities and schools when administering surveys asking youth about their drug use.

    The aim of this study was to evaluate acceptance of treatment after oral sedation with midazolam in dental patients with major neurocognitive disorder. Midazolam is commonly used as premedication in paediatric dentistry, oral surgery and people suffering from dental fear. Little is known about its use in other patient groups. Dental and sedation records of 61 patients (64% women) sedated with midazolam were examined retrospectively. All records came from patients with major neurocognitive disorder who had been referred to a special dental care unit in Sweden due to uncooperative behaviour and sedated with orally administered midazolam between 2006 and 2011. Data concerning dose, degree of acceptance of dental treatment (four-point scale) and number of possible interacting drugs were collected from dental records. On average, the participants were 80 years old (range: 62-93) and used 3.4 possible interacting drugs. The average midazolam dose was 0.11 mg/kg body weight, which is in line with the regional medical guidelines for sedation. Twenty-seven participants (44%) had no cooperation problems when sedated, twenty-six (43%) were treated with minor adaptations, five had poor cooperation, and three were not possible to treat. No statistically significant differences were found for degree of acceptance of treatment and dose or number of possible interacting drugs. Antiepileptics were used by 13% (n=7) with good or quite good acceptance compared to 37% (n=3) among those with poor or no acceptance. Unfavourable side effects were rare; one participant became hyperactive and one drowsier than expected. Sedation with orally administered midazolam seems to be effective and safe in dental treatment of uncooperative persons with major neurocognitive disorder. © 2017 John Wiley & Sons A/S and The Gerodontology Association.

    The safety of a proprietary formulation of buprenorphine hydrochloride administered subcutaneously (SC) to young cats was investigated in a blinded, randomized study. Four cohorts of eight cats aged approximately 4 months were administered saline, 0.24, 0.72 or 1.20 mg/kg/day buprenorphine SC for nine consecutive days, representing 0×, 1×, 3× and 5× of the intended dose. Cats were monitored daily for evidence of clinical reactions, food and water intake and adverse events (AEs). Physical examinations, clinical pathology, vital signs and electrocardiograms (ECGs) were evaluated at protocol-specified time points. Complete necropsy and histopathologic examinations were performed following humane euthanasia. Four buprenorphine-treated cats experienced AEs during the study, two unrelated and two related to study drug administration. The two cats with AEs considered related to drug administration had clinical signs of hyperactivity, difficulty in handling, disorientation, agitation and dilated pupils in one 0.24 mg/kg/day cat and one 0.72 mg/kg/day cat. All of these clinical signs were observed simultaneously. There were no drug-related effects on survival, injection response, injection site inspections, body weight, food or water consumption, bleeding time, urinalysis, respiration rate, heart rate, ECGs, blood pressures, body temperatures, macroscopic examinations or organ weights. Once daily buprenorphine s.c. injections at doses of 0.24, 0.72 and 1.20 mg/kg/day for 9 consecutive days were well tolerated in young domestic cats. © 2015 The Authors.

    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.

    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.

    Full Text Available Introduction: Tamsulosin is alfa 1a-adrenergic antagonist administered to patients with prostatic hypertrophy. It causes the relaxation of the smooth muscles of prostate and urinary bladder and results in symptom alleviation. However, Tamsulosin side effect reflects in the atony of pupil's dilatory muscle, and accordingly, the iris during the phacoemulsification becomes folded and prolapses through the phacoemulsification incision. Moreover, there is no possibility of sufficient pupil dilatation because of the predominating effect of the pupillary m. sphincteris. In order to manage the iridal prolapse during the surgery, a special high-cohesive visco-elastic as well as multi-positioned iridal retractors are being used. Case report: This is a case report of three patients. Common to all of them was that they were all males in the advanced age, had benign prostatic hypertrophy, received Tamsulosin and underwent cataract surgery by phacoemulsification. In all three patients, adequately dilated pupils required for unobstructed performance of phacoemulsification could not be achieved by regular medicaments. In addition, in all three cases, the iris prolapsed through the incision during the surgical intervention. Upon applying the viscoelastic and deepening of the anterior ocular chamber as well as after the placement of iridal retractors in different positions, the operation was successfully brought to an end. Conclusion: In patients administering the Tamsulosin, cataract phacoemulsification is more frequently associated with complications. A special problem is a constant iridal prolapse through the incision. Unfortunately, no so far described method for managing this problem has been fully successful, what was confirmed in our case reports as well. Therefore, the operation for cataract in these patients should be carried out only by most experienced and skillful surgeons.

    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.

    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.

  13. Colon dysregulation in methamphetamine self-administering HIV-1 transgenic rats.

    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.

    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.

    Caffeine is a natural methylxanthine widespread throughout the food industry. Many research studies have shown that caffeine readily crosses the placenta causing teratogenic and embryotoxic effects. The objective of this study was to assess the influence of caffeine, administered at 10°C, on the development of a rat's bone tissue, with particular reference to elemental bone composition using an X-ray microprobe. The research was conducted on white rats of the Wistar strain. The fertilized females were divided into two groups: an Experimental Group (Group E) and a Control Group (Group C). The females in Group E were given caffeine orally (at 10°C) in 30 mg/day doses from the 8(th) - 21(st) day of pregnancy. The females in Group C were given water at the same temperature. The foetuses were used to assess the growth and mineralization of the skeleton. Qualitative analysis of the morphology and mineralization of bones was conducted using the alcian-alizarin method. For calcium and potassium analysis, an X-ray microprobe was used. By staining the skeleton using the alcian-alizarin method, changes in 47 Group E foetuses were observed. The frequency of the development variants in the Group E rats was statistically higher, compared with Group C. On the basis of these results, it can be concluded that caffeine in high doses disturbs the development of bone tissue. An additional factor which enhances the adverse effects of this substance on bone tissue is the temperature of the administered solution (10(o)C). In the Experimental Group, a significant decrease in the calcium level, as well as an increase in the potassium level, was observed. The X-ray microprobe can be a perfect complement to the methods which enable determination of the mineralization of osseous tissue.

    Fentanyl pectin nasal spray (FPNS, Lazanda® in the US and PecFent® in Europe and Australia) is a novel analgesic approved for the management of breakthrough pain in cancer patients. Given that the fentanyl is nasally administered, it is important to understand whether concomitant allergic rhinitis, or its treatment with a vasoconstrictor, would affect its absorption and, potentially, its efficacy or safety. Subjects with a history of allergic rhinitis were screened to identify subjects who developed at least moderate rhinitis symptoms on exposure to pollen allergen (either ragweed or tree) in an environmental exposure chamber (EEC). These were entered into a randomized, three-way crossover study in which each subject received 100 μg of FPNS under three exposure conditions; Control (no rhinitis), Rhinitis (symptomatic without decongestant), Treated (symptomatic with concomitant oxymetazoline). Blood samples for fentanyl were collected over a 24-hour period. A total of 132 subjects was screened to identify 54 for inclusion in the study; 31 were evaluable for pharmacokinetics. Measures of fentanyl absorption (mean or median) were similar between Control and Rhinitis conditions: Cmax 453.0 vs. 467.8 pg/ml; AUCt 1,292.3 vs. 1,325.4 pg×h/ml, AUC0-∞ 1,430.6 vs. 1,387 pg×h/ml and tmax 20 vs. 17 minutes. When oxymetazoline was co-administered, overall fentanyl absorption was slightly reduced (AUC0-∞ 1,362.4 pg×h/ml); but, more clinically relevant were the delayed rate of absorption (tmax 53 minutes) and reduced Cmax (235.3 pg/ml). Patients treated with FPNS will be unaffected by the development of allergic rhinitis; but, if oxymetazoline is prescribed, the patient would benefit from added supervision when oxymetazoline is started and stopped.

    A 56-day floor pen study was conducted to determine the appropriate time to administer toltrazuril (Baycox) (TOL) for control of coccidiosis in broiler chickens. Litter was seeded with field strains of Eimeria acervulina, Eimeria maxima and Eimeria tenella. On Days 0, 21, 35 and 56, all birds and feed were weighed. Starting on Day 14, weekly lesion scores and oocyst counts were performed. The treatments were 125 ppm nicarb (NIC) in the starter to 66 ppm salinomycin (SAL) in the grower with no TOL (NIC/SAL/no TOL), 66 ppm salinomycin in both the starter and the grower but no TOL (SAL/SAL/no TOL), or no in-feed medication with the following TOL treatment: TOL Days 2-3, TOL Days 6-7, TOL Days 10-11, TOL Days 14-15, TOL Days 18-19, and as control NM/NM/no TOL (NM). The withdrawal feed was nonmedicated. TOL was administered in the drinking water at the rate of 7 mg/kg body weight. Oocysts per gram litter and lesion scores showed a significant infection in the NM birds, which peaked about Day 21. The NIC/SAL gave excellent early protection but only moderate protection during the SAL phase. The final performance for the SAL/SAL was significantly less compared to all TOL and NIC/SAL birds. All TOL treatments but Days 2-3 provided good coccidiosis control with accompanying performance. The absence of clinical coccidiosis relapse during the last third of the growout along with moderate oocyst counts and low lesions was indicative of unimpaired coccidiosis immunity. It can be inferred from the overall results that the use of TOL as the sole anticoccidial for two consecutive days in the drinking water between Days 10 and 14 would be the best time for good coccidiosis control allowing full performance.

    Full Text Available Abstract Background This study aimed to examine the effects of intermittent and continuous swimming training on muscle protein metabolism in neonatal alloxan-administered rats. Methods Wistar rats were used and divided into six groups: sedentary alloxan (SA, sedentary control (SC, continuous trained alloxan (CA, intermittent trained alloxan (IA, continuous trained control (CC and intermittent trained control (IC. Alloxan (250 mg/kg body weight was injected into newborn rats at 6 days of age. The continuous training protocol consisted of 12 weeks of swimming training in individual cylinder tanks while supporting a load that was 5% of body weight; uninterrupted swimming for 1 h/day, five days a week. The intermittent training protocol consisted of 12 weeks of swimming training in individual cylinder tanks while supporting a load that was 15% of body weight; 30 s of activity interrupted by 30 s of rest for a total of 20 min/day, five days a week. Results At 28 days, the alloxan animals displayed higher glycemia after glucose overload than the control animals. No differences in insulinemia among the groups were detected. At 120 days, no differences in serum albumin and total protein among the groups were observed. Compared to the other groups, DNA concentrations were higher in the alloxan animals that were subjected to continuous training, whereas the DNA/protein ratio was higher in the alloxan animals that were subjected to intermittent training. Conclusion It was concluded that continuous and intermittent training sessions were effective in altering muscle growth by hyperplasia and hypertrophy, respectively, in alloxan-administered animals.

    Recent investigations revealed that lysophosphatidic acid (LPA), a phospholipid with a growth factor-like activity, plays an important role in the integrity of the gastrointestinal tract epithelium. This paper attempts to clarify the effect of orally administered phosphatidic acid (PA) and LPA on aspirin-induced gastric lesions in mice. Phospholipids, a free fatty acid, a diacylglycerol and a triglyceride at 1 mM (5.7 μmol/kg body weight) or 0.1 mM were orally administered to mice 0.5 h before oral administration of aspirin (1.7 mmol/kg). The total length of lesions formed on the stomach wall was measured as a lesion index. Formation of LPA from PA in the mouse stomach was examined by in vitro (in stomach lavage fluid), ex vivo (in an isolated stomach) and in vivo (in the stomach of a living mouse) examinations of phospholipase activity. Palmitic acid, dioleoyl-glycerol, olive oil and lysophosphatidylcholine did not affect the aspirin-induced lesions. In contrast, phosphatidylcholine (1 mM), LPA (1 mM) and PA (0.1, 1 mM) significantly reduced the lesion index. Evidence for formation of LPA from PA in the stomach by gastric phospholipase A2 was obtained by in vitro, ex vivo and in vivo experiments. An LPA-specific receptor, LPA2, was found to be localized on the gastric surface-lining cells of mice. Pretreatment with PA-rich diets may prevent nonsteroidal anti-inflammatory drug-induced stomach ulcers.

    Treatment of food with ionising radiations in order to increase its shelf-life is largely employed in many countries. Because of restrictions issued by different governments on the use of this technique, in addition to the identification of irradiated foodstuffs, it may be important to determine the radiation dose administered to the foodstuffs. An EPR based protocol to reconstruct the administered dose from samples of irradiated meats (rabbit, pork and duck) within an uncertainty of {+-}25% is reported.

    The expression of the relaxin-3 gene, detected as a new member of the insulin superfamily using human genomic databases, is abundantly present in the brain and testis. Intracerebroventricularly (icv) administered relaxin-3 stimulates food intake. Icv administered relaxin (identical to relaxin-2 in humans) affects the secretion of vasopressin and drinking behavior. Relaxin-3 partly binds relaxin family peptide receptor 1, which is a specific receptor to relaxin. Thus, we hypothesized that relaxin-3 would have physiological effects in the body fluid balance. However, the effects of relaxin-3 in the body fluid balance remain unknown. In the present study, we revealed that icv administered relaxin-3 induced dense Fos-like immunoreactivity (Fos-LI) in the rat hypothalamus and circumventricular organs including the organum vasculosum of the lamina terminalis, the median preoptic nucleus, supraoptic nucleus (SON), the subfornical organ (SFO) and the paraventricular nucleus (PVN), that are related to the central regulation of body fluid balance. Icv administered relaxin-3 (54, 180 and 540 pmol/rat) also induced a significant increase in c-fos gene expression in a dose-dependent manner in the SON, SFO and PVN. Further, icv administered relaxin-3 (180 pmol/rat) significantly increased water intake, and the effect was as strong as that of relaxin-2 (180 pmol/rat). These results suggest that icv administered relaxin-3 activates osmosensitive areas in the brain and plays an important role in the regulation of body fluid balance. Copyright 2010 Elsevier Inc.

    The management of ovarian cancer remains a challenge. Because of the lack of early symptoms, it is often diagnosed at a late stage when it is likely to have metastasized beyond ovaries. Currently, platinum based chemotherapy is the primary treatment for the disease. However acquired drug resistance remains an on-going problem. As cisplatin brings about apoptosis by intrinsic and extrinsic pathways, this study aimed to determine changes in activity of platinum drugs when administered in two aliquots as against a bolus and sought to determine association with changes in GSH, speciation of platinum drugs and changes in protein expression. The efficacy of administering cisplatin, carboplatin and oxaliplatin in two aliquots with a time gap was investigated in ovarian A2780, A2780 cisR , A2780 ZD0473R and SKOV-3 cell lines. The cellular accumulation of platinum, level of platinum − DNA binding and cellular glutathione level were determined, and proteomic studies were carried out to identify key proteins associated with platinum resistance in ovarian A2780 cisR cancer cell line. Much greater cell kill was observed with solutions left standing at room temperature than with freshly prepared solutions, indicating that the increase in activity on ageing was related to speciation of the drug in solution. Proteomic studies identified 72 proteins that were differentially expressed in A2780 and A2780 cisR cell lines; 22 of them were restored back to normal levels as a result of synergistic treatments, indicating their relevance in enhanced drug action. The proteins identified are relevant to several different cellular functions including invasion and metastasis, cell cycle regulation and proliferation, metabolic and biosynthesis processes, stress-related proteins and molecular chaperones, mRNA processing, cellular organization/cytoskeleton, cellular communication and signal transduction. This highlights the multifactorial nature of platinum resistance in which many different

    Complementary therapies are frequently used by breast cancer patients for symptom management; however, documentation of the components of intervention fidelity for studies is not widely available. This report examines the components of intervention fidelity, as put forth by the Treatment Fidelity Workgroup of the Behavior Change Consortium at the National Institutes for Health (NIH-BCC Workgroup), within an ongoing acupressure study of breast cancer survivors with persistent cancer-related fatigue (PCRF). For the acupressure study, the research team designed a randomized, controlled trial (RCT) with 3 parallel groups: (1) stimulating acupressure (intervention group); (2) relaxing acupressure (intervention group); and (3) standard care (control group). At baseline and at wk 3 and wk 6 of the study, women in the acupressure study attended sessions for training and data collection at clinics in the counties of Michigan where they lived. The self-administration of acupressure occurred in participants' homes. Targeted enrollment for the acupressure study is 300 breast cancer survivors who had experienced moderate-to-severe PCRF lasting longer than 1 y beyond treatment. The women are being recruited from 5 counties in Michigan, using the Michigan Tumor Registry to identify potential participants. The subsample report includes 183 participants who have completed all 10 wk of the acupressure study. Most participants in the acupressure study are Caucasian, are married, and have some college education. The acupressure study's educators teach participants in the intervention groups to self-administer either relaxing or stimulating acupressure for a 30-min period on a daily basis for 6 wk. All 3 groups receive the usual care for breast cancer survivors. For the acupressure study, the participants log the frequency of the self-administered acupressure sessions and their fatigue levels. Symptom assessments are made for all groups by telephone in the acupressure study at wk 2

    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

    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

    Plasma disposition of florfenicol in channel catfish was investigated after an oral multidose (10 mg/kg for 10 days) administration in freshwater at water temperatures ranging from 24.7 to 25.9 °C. Florfenicol concentrations in plasma were analyzed by means of liquid chromatography with MS/MS detection. After the administration of florfenicol, the mean terminal half-life (t(1/2)), maximum concentration at steady-state (Css (max)), time of Css (max) (T(max)), minimal concentration at steady-state (Css (min)), and Vc /F were 9.0 h, 9.72 μg/mL, 8 h, 2.53 μg/mL, and 0.653 L/kg, respectively. These results suggest that florfenicol administered orally at 10 mg/kg body weight for 10 days could be expected to control catfish bacterial pathogens inhibited in vitro by a minimal inhibitory concentration value of <2.5 μg/mL. © 2012 John Wiley & Sons Ltd.

    Graphene nanoparticle dispersions show immense potential as multifunctional agents for in vivo biomedical applications. Herein, we follow regulatory guidelines for pharmaceuticals that recommend safety pharmacology assessment at least 10-100 times higher than the projected therapeutic dose, and present comprehensive single dose response, expanded acute toxicology, toxicokinetics, and respiratory/cardiovascular safety pharmacology results for intravenously administered dextran-coated graphene oxide nanoplatelet (GNP-Dex) formulations to rats at doses between 1 and 500 mg/kg. Our results indicate that the maximum tolerable dose (MTD) of GNP-Dex is between 50 mg/kg ≤ MTD < 125 mg/kg, blood half-life < 30 min, and majority of nanoparticles excreted within 24 h through feces. Histopathology changes were noted at ≥250 mg/kg in the heart, liver, lung, spleen, and kidney; we found no changes in the brain and no GNP-Dex related effects in the cardiovascular parameters or hematological factors (blood, lipid, and metabolic panels) at doses < 125 mg/kg. The results open avenues for pivotal preclinical single and repeat dose safety studies following good laboratory practices (GLP) as required by regulatory agencies for investigational new drug (IND) application.

    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.

    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.

    To study the penetration of alpha 1-proteinase inhibitor (A1Pl) into the lungs of healthy dogs, 83 mg/kg of active A1Pl was administered intravenously over 30 min followed by a bolus of 131 I-A1Pl. Animals were lavaged 2 to 72 h after infusion, sequential gamma camera scans were acquired, and urine was analyzed for the excretion of desmosine. After a distribution phase, infused A1Pl left the bloodstream with a half-life of 103 +/- 24 h. Analysis of plasma antiprotease activity demonstrated preservation of function of the infused A1Pl. Lavage fluid A1Pl concentration and activity were significantly increased 24 h after infusion. Gamma camera scans demonstrated that lung, liver, and spleen acquired 131 I-A1Pl similarly; radioactivities per gram of tissue of these organs were similar at autopsy. Excretion of desmosine did not decrease from a baseline of 157 +/- 59 nmol/24 h after A1Pl infusion, indicating no effect of A1Pl infusion on background elastolysis. These data suggest that intravenous administration of A1Pl can raise lung antiproteinase levels within 24 h despite the absence of preferential uptake by the lung of the infused protein

    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.

    Present study aims to depict the role of serotonergic pathways in discrete brain areas (hypothalamus, amygdala, and hippocampus) and their interaction with hypothalamic pituitary adrenal (HPA) axis in alcohol dependence and subsequent withdrawal syndrome in rats. Albino Wistar rats were fed a liquid diet containing alcohol for 4 weeks. Matched control rats were fed isocaloric amounts of the alcohol-free liquid diet, in which the alcohol contribution was substituted with maltose-dextrin. Brain regional tryptophan, 5-hydroxytryptamine (5-HT), 5-Hydroxyindoleacetic acid (5-HIAA) concentrations were determined using high performance liquid chromatography with flourimetric detector. Serum corticosterone was determined spectrofluorimetrically. Data analysis showed that there was significant increase in tryptophan (hippocampus), 5-HT (hippocampus and amygdala) and 5-HT turnover in all the three regions examined when alcohol administered rats were compared with matched controls. In contrast withdrawal from alcohol decreased brain tryptophan, 5-HT and its turnover. It is concluded that the prolong alcohol use boost functions of serotonergic neuronal pathways, in particular, hypothalamus that regulate HPA-axis function and develop tolerance and adaptation. In addition, withdrawal from alcohol exacerbates serotonergic functions that results in failure to suppress corticosterone levels and hence induce low mood states and other signs and symptoms of alcohol withdrawal syndrome.

    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

    To investigate the neurotoxic effects of aluminium (Al) Al was administered: 1) in the diet of the rat (30 mg Al/kg body weight for 6 weeks); 2) as a suspension of aluminium acetate in drinking water of the rat for 3 months and 3) in a long-term study in the mouse in which aluminosilicates were incorporated into a pelleted diet (1035 mg/kg of food over 23 months). In the latter treatment, increased Al was combined with a reduction in calcium and magnesium; a treatment designed to increase absorption of Al into the body. Administration of Al in the drinking water significantly reduced total brain biopterins and BH4 synthesis. However, no significant affect of Al in the diet on total biopterins or BH4 synthesis was found either in the rat or in the long-term study in the mouse. In addition, in the mouse no significant effects of the Al diet on levels of noradrenaline, serotonin, dopamine, 5-HIAA or CAT could be demonstrated. Hence, the occurrence of brain alterations may depend on the Al species present and the method of administration. Al salts in drinking water may increase brain tissue levels compared with the administration of a more insoluble species. Since alterations in biopterin metabolism are also a feature of Alzheimer's disease (AD) these results support the hypothesis that Al in the water supply may be a factor in AD.

    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.

    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.

    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.

    Previous work showed that Tepary bean ( Phaseolus acutifolius ) lectins exhibit differential cytotoxic effects on cancer cell lines by apoptosis induction. In vivo studies using a Tepary bean lectin fraction (TBLF, 50 mg/kg of body weight) after colon cancer induction in rats showed that TBLF inhibited early precancerous lesions without systemic toxicity however, loss of body weight gain and activation of immune cells were observed. In order to know more about the possible adverse effects, we evaluated the administration of TBLF on digestive and immune organs. Sprague Dawley rats were administered TBLF for six weeks and allowed to recover for two weeks. Immune activation was observed through an increased lymphocyte-granulocyte ratio, an increased number of lymphoid follicles in intestinal Peyer's patches and a slight expansion of the splenic white pulp. Atrophy was observed in small intestine villi and crypt foci of the colon without normalization after the recovery period. Pancreas histopathology showed hypertrophy after the six-week administration period, particularly vacuolation and trabecular widening; but after the two-week recovery period atrophy was observed, suggesting a partial compensatory type process. Our results show that TBLF activates the immune system and affects digestive organs through direct interaction with intestinal epithelium, and indirectly by producing pancreatic hyperfunction. Further work will focus in longer recuperation periods after TBLF treatment.

    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.

    The safety of natural drugs is defined by their side effects and toxicity as well as any interactions that may occur if taken together with other drugs. In particular, it is essential to identify synergies, antagonisms and other types of interference with other drugs so that the correct choice can be made from the range of phytomedicines available. The aim of this work was to investigate changes in the pharmacological effect of diazepam (2 mg/kg) on the CNS when administered together with a medicinal plant: Eucalyptus globulus Labill. (eucalyptus 6 mg/kg and 3.25 mg/kg) or Uncaria tomentosa (Willd. ex Roem. & Schult). DC. (cat's claw, 7.14 mg/kg and 3.54 mg/kg). Various different psychopharmacological effects were evaluated through assessing exploratory behavior, muscle relaxation and spontaneous motor activity. Both phytodrugs interacted with the benzodiazepine. Eucalyptus had an inhibitory effect at both doses and could be useful at the highest dose in cases where the desired effect of the depressant is moderate anxiolytic activity without marked muscle relaxation. Cat's claw, at both doses, enhanced the action of diazepam on spontaneous motor activity and, at the lowest dose, exploratory ability. These herbal drugs could be useful for their antiinflammatory activity in musculoskeletal pathologies treated with benzodiazepines. Copyright © 2011 John Wiley & Sons, Ltd.

    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.

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. Copyright © 2016 The Authors.

    The current study tested the effectiveness of a self-administered, cognitive-behavioral intervention targeting criminal thinking for inmates in segregated housing: Taking a Chance on Change (TCC). Participants included 273 inmates in segregated housing at state correctional institutions. Reductions in criminal thinking, as assessed by the Psychological Inventory of Criminal Styles-Simplified Version, were found in the general criminal thinking score as well as the proactive and reactive composite scores. Examination of demographic predictors of change (i.e., age, years of education, length of sentence) revealed older and more educated participants decreased in criminal thinking more than younger and less educated participants. For a subset of 48 inmates, completion of TCC was associated with significant reduction of disciplinary infractions. Reductions in reactive criminal thinking predicted reductions in disciplinary infractions. Although further research is needed to determine the effectiveness of TCC in reducing recidivism, the reductions in criminal thinking and disordered conduct suggest this is a promising intervention and mode of treatment delivery. By utilizing self-directed study at an accessible reading level, the intervention is uniquely suited to a correctional setting where staff and monetary resources are limited and security and operational issues limit the feasibility of traditional cognitive-behavioral group treatment.

    Full Text Available Collagen peptides (CPs have demonstrated to exert beneficial effects on skin photoaging. However, little has been done to evaluate their effects on chronologically aged skin. Here, the effects of CPs from bovine bone on skin aging were investigated in chronologically aged mice. 13-month-old female Kunming mice were administered with CPs from bovine bone (200, 400 and 800 mg/kg body weight/day or proline (400 mg/kg body weight/day for 8 weeks. Mice body weight, spleen index (SI and thymus index (TI, degree of skin laxity (DSL, skin components, skin histology and antioxidant indicators were analyzed. Ingestion of CPs or proline had no effect on mice skin moisture and hyaluronic acid content, but it significantly improved the skin laxity, repaired collagen fibers, increased collagen content and normalized the ratio of type I to type III collagen in chronologically aged skin. CPs prepared by Alcalase performed better than CPs prepared by collagenase. Furthermore, CPs intake also significantly improved the antioxidative enzyme activities in skin. These results indicate that oral administration of CPs from bovine bone or proline can improve the laxity of chronologically aged skin by changing skin collagen quantitatively and qualitatively, and highlight their potential application as functional foods to combat skin aging in chronologically aged process.

    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.

    It has been reported that oral administration of lipopolysaccharide (LPS) recovers an individual's immune condition and induces the exclusion of foreign matter, inflammation and tissue repair. We orally administered LPS from the wheat symbiotic bacteria Pantoea agglomerans, which has been ingested and proven to be safe, to cancer patients. Our observation of clinical improvements resulting from this treatment are reported. Sixteen cancer patients who exhibited declined small intestinal immune competence were treated between June and September, 2015. Diagnosis was based on our evaluation on small intestinal immune competence and macrophage activity. The state of malignant tumors at 3 months after starting this treatment was complete recovery for 3 cases, remission for 7 cases, maintenance for 4 cases, exacerbation for 1 case and death for 1 case (total response rate=62.5%). Small intestinal immune competence and macrophage activity recovered in all cases, suggesting that oral administration of LPS contributes to disease improvement. No clear side-effects that appeared to be related to LPS intake were noted. Intake of an appropriate level of Pantoea agglomerans LPS recovers small intestinal immune competence and macrophage activity, contributing to improvement of malignant tumors' therapy.

    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.

    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

    This research was designed to study sexual differences in place conditioning induced by morphine in offspring born of female Wistar rats mated with drug-naïve males. Mothers were exposed to morphine during the 14(th)-16(th) days of gestational. Control dams were simply saline-injected. Female and male virgin offspring born of morphine-treated or saline-treated mothers were separately housed until become fully matured. A 3-day schedule of an unbiased conditioning procedure was used to the induce conditioning to morphine (2.5-7.5 mg/Kg, SC) in the offspring. According to the results, female offspring born of saline-administered mothers were morphine place-conditioned at lower doses of opioid (2.5 mg/Kg) in comparison to the males. An increase in locomotor activity in the females at 7.5 mg/Kg of opioid was also revealed. In contrast, administration of morphine (2.5-7.5 mg/Kg, SC), induced a significant aversion in either sexes of offspring born of morphine-exposed mothers. Moreover, female offspring of this category acquired more pronounced aversion at higher doses of morphine than males. In addition, a significant morphine-dose effect (7.5 mg/Kg, SC) on locomotor activity of these females' offspring was observed. This study may highlight sex differences in conditioning effects induced by morphine between offspring derived of morphine-treated mothers and those of saline-treated.

    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.

  16. Effect of Intravenously Administered Crystalloid Solutions on Acid-Base Balance in Domestic Animals.

    Intravenous fluid therapy can alter plasma acid-base balance. The Stewart approach to acid-base balance is uniquely suited to identify and quantify the effects of the cationic and anionic constituents of crystalloid solutions on plasma pH. The plasma strong ion difference (SID) and weak acid concentrations are similar to those of the administered fluid, more so at higher administration rates and with larger volumes. A crystalloid's in vivo effects on plasma pH are described by 3 general rules: SID > [HCO3-] increases plasma pH (alkalosis); SID solutions has little to no effect on plasma pH because of their low titratable acidity. Appreciation of IV fluid composition and an understanding of basic physicochemical principles provide therapeutically valuable insights about how and why fluid therapy can produce and correct alterations of plasma acid-base equilibrium. The ideal balanced crystalloid should (1) contain species-specific concentrations of key electrolytes (Na + , Cl - , K + , Ca ++ , Mg ++ ), particularly Na + and Cl - ; (2) maintain or normalize acid-base balance (provide an appropriate SID); and (3) be isosmotic and isotonic (not induce inappropriate fluid shifts) with normal plasma.

    Using a whole-body radiation detector, the total-body retention of 47 Ca 7 days after oral administration of the isotope to patients with various disorders of calcium metabolism was measured. The percent retention of 47 Ca given with 90 mg of unlabeled (carrier) calcium varied with the calcium metabolic status as follows: normals (n = 14), 33--43 percent (mean 38); primary hyperparathyroidism (n = 28), 32--74 percent (mean 52); idiopathic hypercalciuria (n = 9), 34--49 percent (mean 42); and hypercalcemia of other etiology (n = 3), 23--26 percent (mean 25). Almost half (13/28) of those with hyperparathyroidism showed a retention above 55 percent, distinguishing them from subjects with idiopathic hypercalciuria. Retention of 47 Ca correlated poorly with clinical measures of severity of hyperparathyroidism. When isotope was diluted with a smaller amount of carrier calcium (20 mg), retention was increased in normals (n = 5) to 46--54 percent (mean 50) and in hyperparathyroidism (n = 5) to 64--87 percent (mean 73). After surgical cure of hyperparathyroidism retention of isotope returned toward normal in 5 of 7 subjects. Whole-body retention of orally administered 47 Ca may prove useful in detecting hyperparathyroidism in subjects with mild hypercalcemia or hypercalciuria. (U.S.)

    Full Text Available The effect of N-tetramethylene dithiocarbamate (ATC as a chelating agent on the excretion of cadmium was evaluated in cadmium-poisoned Wistar rats following administration through food and drink. The present research aimed to characterize the potential efficiency of ATC as an orally administered chelator drug after cadmium administration for 60 days. This chelator significantly enhanced the urinary and biliary excretion of cadmium and restored the altered levels of iron. Cadmium and iron concentrations in different tissues were determined by graphite furnace and flame atomic absorption spectrometry (GF AAS and F AAS methods, respectively. The chelation therapy results show that ATC is able to remove cadmium ions from different tissues while iron concentration returned to the normal level and the clinical symptoms were also reduced. In summary, we conclude that ATC is able to mobilize and promote the excretion of cadmium in rat organs and reduce the side effects and general symptoms of toxicity caused by cadmium and might be useful for preliminary testing of the efficacy of chelating agents in human body. However, these results should be confirmed in different experimental models before extrapolation to other systems. This testing procedure of course does not provide all the relevant answers for evaluating the efficiency of chelating agents in cadmium toxicity.

    The medical applications of aptamers have recently emerged. We developed an antagonistic thioaptamer (ESTA) against E-selectin. Previously, we showed that a single injection of ESTA at a dose of 100 μg inhibits breast cancer metastasis in mice through the functional blockade of E-selectin. In the present study, we evaluated the safety of different doses of intravenously administered ESTA in single-dose acute and repeat-dose subacute studies in ICR mice. Our data indicated that intravenous administration of up to 500 μg ESTA did not result in hematologic abnormality in either study. Additionally, intravenous injection of ESTA did not affect the levels of plasma cytokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, GM-CSF, IFN-γ, and TNF-α) or complement split products (C3a and C5a) in either study. However, repeated injections of ESTA slightly increased plasma ALT and AST activities, in accordance with the appearance of small necrotic areas in the liver. In conclusion, our data demonstrated that intravenous administration of ESTA does not cause overt hematologic, organs, and immunologic responses under the experimental conditions. - Highlights: • Intravenous administration of ESTA was well tolerated. • ESTA up to 500 μg does not cause hematologic, organs, and immunologic responses. • ESTA-mediated hepatic abnormality was considered minor.

    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 microL 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 microL 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 microL 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.

  2. 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

    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.

    (1) To describe the results of a web-based teaching module used by registered nurses to identify patients at risk of aspiration and (2) to determine accuracy of the registered nurse-administered 3-ounce water swallow challenge protocol, that is, drinking three ounces of water, a basic cognitive screen and oral mechanism evaluation, when compared with blinded ratings from speech-language pathology. Early identification of potential swallowing problems is important prior to ingestion of food, fluid and medications. Unfortunately, current nurse-administered screens use a variety of non-evidence-based assessments. It would be beneficial to use a valid, reliable and evidence-based screen, that is, the Yale swallow protocol. Prospective, blinded, referral-based. Fifty-two registered nurses and 101 inpatients participated. First, each participant was administered the 3-ounce water swallow challenge protocol by a speech-language pathologist. Second, a nurse administered the protocol to the same patient within one hour and independently recorded results and diet recommendations. The nurse was blinded to the study's purpose and results of the speech-language pathologist's initial screening. Out of view, but simultaneous with the nurse-administered protocol, a speech-language pathologist rerated the patient's challenge for comparison with initial results and determined the accuracy of the nurse-administered protocol. Intra- and inter-rater protocol agreements for the two speech-language pathologists were 100%. Inter-rater protocol agreement between registered nurses and speech-language pathologists was 98·01%. Results confirm the reliability and accuracy of a registered nurse-administered Yale swallow protocol. The consequence of 98% accuracy combined with previously reported 96·5% sensitivity, 97·9% negative predictive value and preventable prandial pulmonary aspiration as a cause of nosocomial infection is an important goal for all acute care hospitalised patients deemed

    2014-12-01

    This study aimed to examine the meanings that nurses attached to the 'treatments' administered to cure 'sexual deviation' (SD) in the UK, 1935-1974. In the UK, homosexuality was considered a classifiable mental illness that could be 'cured' until 1992. Nurses were involved in administering painful and distressing treatments. The study is based on oral history interviews with fifteen nurses who had administered treatments to cure individuals of their SD. The interviews were transcribed for historical interpretation. Some nurses believed that their role was to passively follow any orders they had been given. Other nurses limited their culpability concerning administering these treatments by adopting dehumanising and objectifying language and by focussing on administrative tasks, rather than the human beings in need of their care. Meanwhile, some nurses genuinely believed that they were acting beneficently by administering these distinctly unpleasant treatments. It is envisaged that this study might act to reiterate the need for nurses to ensure their interventions have a sound evidence base and that they constantly reflect on the moral and value base of their practice and the influence that science and societal norms can have on changing views of what is considered 'acceptable practice'. © 2013 The Authors.

    Full Text Available Health disparities (HD continue to persist in the United States which underscores the importance of using low-cost, accessible, evidence-based strategies that can improve health outcomes, especially for chronic conditions that are prevalent among underserved minority populations. Complementary/integrative health modalities, particularly self-administered mind-body practices (MBP, can be extremely useful in reducing HD because they are intrinsically patient-centered and they empower patients to actively engage in self-care of health and self-management of symptoms. Interprofessional healthcare providers and patients can engage in powerful partnerships that encompass self-administered MBP to improve health. This is a call to action for interprofessional researchers to engage in high-quality research regarding efficacy and cost-effectiveness of self-administered MBP, for practitioners to engage patients in self-administered MBP for health promotion, disease prevention, and symptom management, and for healthcare institutions to integrate self-administered MBP into conventional health practices to reduce HD in their communities.

    To describe the rationale behind the choice of fentanyl administration forms as reported by Danish nurses and physicians specializing in pain management. Sixty nurses and 60 physicians specializing in pain management in Denmark were contacted via an Internet survey system to perform two Delphi surveys. In the brainstorming phase, the main reasons for administering and not administering fentanyl patches and oral transmucosal fentanyl citrate (OTFC) were identified. In the second phase, the nursing and medical experts rated the importance of these reasons on an 11-point Numerical Rating Scale. Responses from 10 pain nurses and 14 pain doctors were used for the final analysis. Impossible or difficult oral intake of analgesia was the most important reason to administer fenantyl patches, whereas patients' dermatological problems and neuropathic pain origin were the most important reasons for not administering fenantyl patches in both panels. OTFC was presented as an alternative or second choice administration form for breakthrough cancer pain by both nurses and doctors. A damaged mouth, the high cost, and energy required for administration of this medication were reported as the main reasons why OTFC was only rarely prescribed to cancer pain patients in Denmark. The reasons for administering fentanyl in different administration forms reported by Danish pain nurses and pain specialists partly differed from those derived from the literature. Studies of pain management traditions could improve the understanding of the reasons for analgesic administration.

    Current methods of improving medication adherence for health problems are mostly complex, labour-intensive, and not reliably effective. Medication 'reminder packaging', which incorporates a date or time for a medication to be taken in the packaging, can act as a reminder to improve adherence. This review of reminder packaging is an update of our 2006 Cochrane review. The objective of this review was to determine the effects of reminder packaging aids for self-administered medication/s taken for at least one month, on adherence and other outcomes. We updated searches of the Cochrane Central Register of Controlled Trials (CENTRAL) and the Database of Abstracts of Reviews of Effects (DARE) (The Cochrane Library Issue 9, 2010), MEDLINE, EMBASE, CINAHL and PsycINFO from the database start dates to September 2010. We searched Current Controlled Trials to identify trials in progress. We performed a cited reference search on the Science Citation Index to identify papers that had cited the original systematic review.We also searched the Internet, contacted packaging manufacturers, and checked abstracts from the Pharm-line database and reference lists from relevant articles. We did not apply any language restrictions. We selected randomised controlled trials with at least 80% follow up. We intended to do a sensitivity analysis of those studies that analysed their data on an intention-to-treat basis. Included studies compared a reminder packaging device with no device, for participants taking self-administered medications for at least one month. Three review authors independently assessed studies for inclusion, assessed quality, and extracted data from included studies. Where considered appropriate, data were combined for meta-analysis, or were reported and discussed in a narrative. We included twelve studies containing data on 2196 participants; four of these studies were newly included in this 2011 update of our 2006 Cochrane review.Six intervention groups in four trials

Successful management of severe cancer pain may require invasive treatment. However, a patient's refusal of an invasive procedure necessitates that clinicians consider alternative options. Objective: Intrathecal bupivacaine delivery as a viable treatment of intractable pain is well documented. There are no data on rectal bupivacaine use in cancer patients or in the treatment of cancer tenesmoid pain. This study aims to demonstrate that bupivacaine administered rectally could be a step in between the current treatment options for intractable cancer pain (conventional/conservative analgesia or invasive procedures, and to evaluate the effect of the mode of administration (intrathecal versus rectal on the bupivacaine plasma concentration.Cases: We present two Caucasian, elderly inpatients admitted to hospice due to intractable rectal/tenesmoid pain. The first case is a female with vulvar cancer, and malignant infiltration of the rectum/vagina. Bupivacaine was used intrathecally (0.25–0.5%, 1–2 mL every 6 hours. The second case is a female with ovarian cancer and malignant rectal infiltration. Bupivacaine was adminstered rectally (0.05–0.1%, 100 m

    Anticancer drug treatment, particularly with anthracyclines, is frequently associated with cardiotoxicity, an effect exacerbated by trastuzumab. Several compounds are in use clinically to attenuate the cardiac-damaging effects of chemotherapy drugs, including angiotensin-converting enzyme (ACE) inhibitors, beta-blockers, the anti-diabetic drug metformin, and dexrazoxane. However, there is concern that the cardiac-preserving mechanisms of these drugs may also limit the anticancer efficacy of the chemotherapeutic agents. Herein two breast cancer cell lines, SKBr3 and BT474, overexpressing human epithelial receptor 2 (HER2), the target of the humanised antibody trastuzumab, were treated with a range of concentrations (20-2000 nM) of doxorubicin with and without trastuzumab in the presence of clinically relevant doses of the ACE inhibitor enalapril, the beta-blocker carvedilol, metformin or dexrazoxane, and cell survival determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. None of the drugs reduced the anticancer effect of doxorubicin or trastuzumab (nor of the two drugs combined). Using Chou and Talalay's combination index, dexrazoxane and doxorubicin were found to act synergistically on the SKBr3 cells. (18)F-Fluoro-2-deoxy-D-glucose ((18)F-FDG) incorporation was reduced by treatment of SKBr3 cells with doxorubicin and this was shown to be due to reduced phosphorylation of (18)F-FDG in doxorubicin-treated cells. Treatment of SKBr3 cells with doxorubicin and dexrazoxane further reduced (18)F-FDG incorporation, indicating that the synergy in the cytotoxicity of these two drugs was reflected in their combined effect on (18)F-FDG incorporation. Commonly administered cardioprotective drugs do not interfere with anticancer activity of doxorubicin or tratsuzumab. Further studies to establish the effect of cardioprotective drugs on anticancer drug efficacy would be beneficial. Copyright© 2016 International Institute of Anticancer Research

    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.

    The efficacy of orally administered afoxolaner against adult dog fleas, Ctenocephalides canis, was evaluated in a controlled, blinded study. A total of 32 dogs were infested with 100 adult unfed fleas approximately 24h prior to treatment and then at weekly intervals for 5 weeks after treatment. Live fleas were counted upon removal at 12h (for 16 dogs) and 24h (for the remaining 16 dogs) after treatment (for counts performed the first week) or after infestation (for counts performed on subsequent weeks). In addition, flea eggs were collected from each pen and counted for the dogs with flea removal at 24h. Dosing of individual dogs was achieved using a combination of the chewable tablets to be as close as possible to the minimum effective dose of 2.5mg/kg. The percent efficacy of the afoxolaner treatment was ≥ 99.0% for all 24-h flea counts. For flea counts performed 12h after treatment or infestations, the percent efficacy was ≥ 94.1% up to Day 21. After Day 1, no flea eggs were recovered from the afoxolaner treated group, providing 100% reduction in numbers of flea eggs recovered versus untreated control group. This study confirmed that a single oral treatment with afoxolaner provided excellent efficacy against infestations by C. canis within 12-24h after treatment, prevented re-infestations, and completely prevented egg production from new flea infestations for up to 5 weeks.

  14. Market surveillance panel monitoring report on the IMO-administered electricity markets : Executive summary

    International Nuclear Information System (INIS)

    2002-01-01

    The electricity market in Ontario was opened on May 1, 2002. This document provides the executive summary for the first monitoring report prepared by the Market Surveillance Panel covering the period May to August 2002. In the introductory chapter of the main report, explanations are provided on why competition, when effective, benefits consumers, as well as touching on the conditions for the design of an effective competitive electricity market with special emphasis on the electricity market in Ontario and its operations. For the period under review, the report presents a description and analysis of the activities and operations of the Independent Electricity Market Operator (IMO)-administered markets (focus on energy markets). Rising costs for hydroelectric power and very high temperatures combined in July and August resulting in record levels of demand. It became apparent that the province relies on imports to satisfy demand. The figures reveal that reliability in July and August depended on imports 21 per cent of the time. A serious shortage of generating capacity exists in Ontario and steps to rectify the situation should be initiated to ensure reliability of electricity supply for next summer. Prospective entrants in the electricity market in Ontario may not be receiving clear, credible and consistent signals. Effective use of existing or potential transmission capacity may not always be made by the system. The lowering of consumption by consumers is difficult since consumers are not properly equipped, resulting in their lack of power to discipline price increases from suppliers. The future evolution of the market must be planned and measures implemented to enhance the effectiveness of competition. The incentives effects for some aspects of the market design do not completely satisfy the Panel

  15. Reduction of Pavlovian Bias in Schizophrenia: Enhanced Effects in Clozapine-Administered Patients.

    Directory of Open Access Journals (Sweden)

    Matthew A Albrecht

    Full Text Available The negative symptoms of schizophrenia (SZ are associated with a pattern of reinforcement learning (RL deficits likely related to degraded representations of reward values. However, the RL tasks used to date have required active responses to both reward and punishing stimuli. Pavlovian biases have been shown to affect performance on these tasks through invigoration of action to reward and inhibition of action to punishment, and may be partially responsible for the effects found in patients. Forty-five patients with schizophrenia and 30 demographically-matched controls completed a four-stimulus reinforcement learning task that crossed action ("Go" or "NoGo" and the valence of the optimal outcome (reward or punishment-avoidance, such that all combinations of action and outcome valence were tested. Behaviour was modelled using a six-parameter RL model and EEG was simultaneously recorded. Patients demonstrated a reduction in Pavlovian performance bias that was evident in a reduced Go bias across the full group. In a subset of patients administered clozapine, the reduction in Pavlovian bias was enhanced. The reduction in Pavlovian bias in SZ patients was accompanied by feedback processing differences at the time of the P3a component. The reduced Pavlovian bias in patients is suggested to be due to reduced fidelity in the communication between striatal regions and frontal cortex. It may also partially account for previous findings of poorer "Go-learning" in schizophrenia where "Go" responses or Pavlovian consistent responses are required for optimal performance. An attenuated P3a component dynamic in patients is consistent with a view that deficits in operant learning are due to impairments in adaptively using feedback to update representations of stimulus value.

    To evaluate the impact of a Federal drug information center initiating engagement with stakeholders on a Facebook Page administered by a Federal Agency. The U.S. Food and Drug Administration (FDA) Facebook page from July 21, 2014, to October 18, 2014. FDA's Division of Drug Information (DDI) in the Center for Drug Evaluation and Research (CDER) Office of Communications serves as a federal drug information center providing timely, accurate, and useful information on CDER initiatives and CDER-regulated products. We report a 90-day (July 21 to October 18, 2014) pilot during which DDI pharmacists monitored and moderated comments received on FDA's Facebook page to identify those warranting a reply. Once identified, DDI pharmacists replied within 2 business days. Impact was measured by comparing the average number of Likes, Shares, and Reach for Facebook posts before and after the pilot. Additional metrics collected include the number of DDI replies provided to stakeholders' comments and the number of DDI replies provided on time (within 2 business days). During the pilot, DDI contributed 14 posts. On average, each post reached 23,582 more individuals (an increase of 187% compared with pre-pilot posts). On average, each post also received 463 more Likes (450% increase) and 130 more Shares (271% increase). DDI pharmacists replied to 3% (121/3994) and hid 0.58% (23/3994) of Facebook comments received during the 90-day period. All actions were taken within 2 business days. Initiating social engagement had a positive impact on FDA's Facebook page. Published by Elsevier Inc.

    The determination of dosing regimens for the treatment of malaria is largely empirical and thus a better understanding of the pharmacokinetic/pharmacodynamic properties of antimalarial agents is required to assess the adequacy of current treatment regimens and identify sources of suboptimal dosing that could select for drug-resistant parasites. Mefloquine is a widely used antimalarial, commonly given in combination with artesunate. Mefloquine pharmacokinetics was assessed in 24 healthy adults and 43 patients with Plasmodium falciparum malaria administered mefloquine in combination with artesunate. Population pharmacokinetic modelling was conducted using NONMEM. A two-compartment model with a single transit compartment and first-order elimination from the central compartment most adequately described mefloquine concentration-time data. The model incorporated population parameter variability for clearance (CL/F), central volume of distribution (VC/F) and absorption rate constant (KA) and identified, in addition to body weight, malaria infection as a covariate for VC/F (but not CL/F). Monte Carlo simulations predict that falciparum malaria infection is associated with a shorter elimination half-life (407 versus 566 h) and T>MIC (766 versus 893 h). This is the first known population pharmacokinetic study to show falciparum malaria to influence mefloquine disposition. Protein binding, anaemia and other factors may contribute to differences between healthy individuals and patients. As VC/F is related to the earlier portion of the concentration-time profiles, which occurs during acute malaria, and CL/F is more related to the terminal phase during convalescence after treatment, this may explain why malaria was found to be a covariate for VC/F but not CL/F. © The Author 2014.

    To evaluate the safety of Curcuma aromatica oil gelatin microspheres (CAO-GMS) infused via hepatic artery against primary liver cancer. The safety of CAO-GMS was evaluated in view of its acute toxicity in rats, long-term toxicity in Beagle dogs and general pharmacology in rats and mongrel dogs. The 50% lethal dose (LD50) of CAO-GMS infused via the hepatic artery was 17.19 mg/kg, and the serum biochemical indices of dying rats after the administration changed markedly while those of survived rats did not. Subsequent pathological examination of the tissues from the dead rats indicated improper embolism. Similar edema and small necrotic foci in the hepatic lobule were found in the hepatic tissue of rats receiving 10 and 5 mg/kg CAO-GMS and GMS 60 d after the last administration, while not in the rats of the blank control group, indicating that microspheres infused via the hepatic artery may induce irreversible liver damage dose-dependently. General pharmacological study showed that the activities (posture and gait), respiration frequency, blood pressure or heart rate of the dogs were not affected by CAO-GMS, nor were salivation, tremor or pupil changes of the rats observed or their balancing ability compromised, suggesting CAO-GMS infused via the hepatic artery did not significantly affect the nervous, respiratory and cardiovascular systems. CAO-GMS embolization administered via the hepatic artery is safe but undesired embolization induced by vascular variation should be given due attention in its clinical application. Individualized embolization dosage and super-selective catheterization technique are recommended to avoid undesired embolism and reduce complications.

    The purpose of this study was to evaluate the feasibility of implementing a video-module-based mindfulness pilot program intended to reduce stress, improve well-being, and develop mindfulness skills in physicians in a community hospital setting. Preliminary findings are presented. Using a single-sample, pre-post study design, we administered an eight-week mindfulness training offered as part of a wellness initiative for medical staff in a suburban community hospital. Participants enrolled on a first-come, first-served basis. Participants engaged in three 90-min in-person trainings, weekly online video-module trainings, and weekly teleconference coaching calls. Video-module trainings were available at all times, to be accessed at the participants׳ convenience. Journals and a guided meditation audio library were also provided. Physician stress, well-being (emotional exhaustion, depersonalization of patients, and sense of personal accomplishment), and mindfulness skills (observing, describing, acting with awareness, and accepting without judgment) were evaluated at baseline, end-of-program, and eight weeks post-intervention using well-validated instruments. A total of 23 physicians enrolled and 19 completed the program. Compared to baseline, statistically significant decreases in stress, personal accomplishment, and emotional exhaustion were observed at end-of-program and eight weeks post-intervention (all P mindfulness skills were observed at end-of-program; these increases persisted for describing, acting with awareness, and accepting without judgment at eight weeks post-intervention (all P mindfulness program can decrease stress, increase well-being, and develop lasting mindfulness skills in physicians.

    Literature reports regarding the efficacy of efavirenz (EFV) 600 mg with rifampin (RIF) are not consistent. Evaluation of a drug-drug interaction (DDI) study and supportive semi-mechanistic population pharmacokinetic (PK) analyses were undertaken to help delineate this issue. DDI study and supportive semi-mechanistic population PK analyses were provided by BMS. Population PK analysis was based on six studies with intensive EFV PK sampling. An ACTG study with sparse PK sampling was used for model evaluation. Simulations compared EFV exposure at various doses in combination with RIF to EFV exposures at 600 mg once daily (QD). Effects of CYP2B6 genotypes on the magnitude of EFV-RIF interaction were also explored. In DDI study, co-administering EFV 600 mg QD and RIF reduced mean EFV exposure by ~ 30%. Population PK model provided acceptable predictive performance of central tendency and variability for EFV C0, Cmax, and AUC. Simulations predicted that increasing EFV to 800 mg QD with RIF would result in EFV AUC and Cmax similar to EFV 600 mg QD alone. EFV AUC and Cmax were ~ 2 times higher in subjects with reduced function CYP2B6 genotypes. However, the RIF effect was consistent across all genotypes. EFV dose adjustment to 800 mg QD did not increase the risk of overexposure compared to 600 mg EFV QD within each genotype. Dose adjustment based on matching systemic exposure was recommended to mitigate the potential for sub-therapeutic EFV exposures. Our review did not reveal any safety concerns in subjects receiving EFV 800 mg QD with RIF.

    Thimerosal is one of the best-known preservative agents for vaccines in the world but a relationship between its use and autism has long been suspected so that its effects on the brain need more detailed research. We here examined the influence of lipopolysaccharide injury to the blood-brain barrier on the penetration of mercury from thimerosal into mouse cerebrums, as well as the effect of chelator of heavy metals on cerebrum mercury content. Mercury can be expected to be detected in the cerebrum of normal mice, because the metal is present in standard mouse chow. When 60μg/kg of thimerosal was subcutaneously injected into the mouse, the mercury content in the cerebrum was significantly higher 48h after the thimerosal injection with a maximum peak after 72h. In addition, mercury content in the cerebrum was still higher on day 7 than in the control group. When lipopolysaccharide was pre-injected into mice to induce damage on blood-brain barrier, the mercury content in the cerebrum was significantly higher at 24 and 72h after the injection of 12μg/kg of thimerosal compared to the control group, this dose alone does not cause any increase. The mercury content in the cerebrums of mice was decreased to the control group level on day 7 when a chelator, dimercaprol, was administered once a day from days 3 to 6 after a 60μg/kg, s.c. injection. In addition, d-penicillamine as a chelator decreased the mercury contents in the cerebrum after the high dose administration. In conclusion, a physiological dose of thimerosal did not increase the content of mercury in the cerebrum, but levels were increased when damage to the blood-brain barrier occurred in mice injected with thimerosal. In addition, a chelator of heavy metals may be useful to remove mercury from the cerebrum. Copyright © 2007 Elsevier B.V. All rights reserved.

    The efficacy, tolerability and the morphine-sparing effects of lornoxicam were compared with those of tenoxicam when used preoperatively in patients undergoing laparoscopic cholecystectomy. In this prospective, double-blind study, 60 ASA I-II patients undergoing laparoscopic cholecystectomy were randomized equally to receive intravenous tenoxicam 40 mg (Group T) or lornoxicam 16 mg (Group L), preemptively. Three patients withdrew from the study, so 57 patients were included in the analysis. In the postoperative period, the first morphine demand times, pain scores, side-effects and cumulative morphine consumptions were evaluated during the first 24 h. The patient characteristics data and the duration of surgery were similar between two groups, except for body weights (P = 0.002). The first morphine demand time was significantly longer in Group L (P = 0.037), but the pain levels did not differ. The mean pain scores were higher in Group T in the 15 min (P = 0.036), 1 h (P = 0.020), 2 h (P = 0.001) and 4 h (P = 0.0042) after extubation. A statistically significant difference between two groups was found in calculated cumulative morphine consumptions per kilogram in the 15 min (P = 0.037), 30 min (P = 0.016), and 1 h (P = 0.004) and 2 h (P = 0.013) between two groups. There was no difference in the severity of nausea but 13 patients in Group T and five patients in Group L had vomiting (P = 0.018). Patient satisfaction was similar in the two groups. Preoperatively administered lornoxicam 16 mg significantly prolonged the first morphine demand time, reduced postoperative morphine consumption during the first 4 h and caused significantly fewer adverse effects when compared with tenoxicam after laparoscopic cholecystectomy.

    Cannabidiol (CBD) is hypothesized as a potential treatment for opioid addiction, with safety studies an important first step for medication development. We determined CBD safety and pharmacokinetics when administered concomitantly with a high-potency opioid in healthy subjects. This double-blind, placebo-controlled cross-over study of CBD, coadministered with intravenous fentanyl, was conducted at the Clinical Research Center in Mount Sinai Hospital, a tertiary care medical center in New York City. Participants were healthy volunteers aged 21 to 65 years with prior opioid exposure, regardless of the route. Blood samples were obtained before and after 400 or 800 mg of CBD pretreatment, followed by a single 0.5 (session 1) or 1.0 μg/kg (session 2) of intravenous fentanyl dose. The primary outcome was the Systematic Assessment for Treatment Emergent Events (SAFTEE) to assess safety and adverse effects. CBD peak plasma concentrations, time to reach peak plasma concentrations (tmax), and area under the curve (AUC) were measured. SAFTEE data were similar between groups without respiratory depression or cardiovascular complications during any test session. After low-dose CBD, tmax occurred at 3 and 1.5 hours in sessions 1 and 2, respectively. After high-dose CBD, tmax occurred at 3 and 4 hours in sessions 1 and 2, respectively. There were no significant differences in plasma CBD or cortisol (AUC P = NS) between sessions. Cannabidiol does not exacerbate adverse effects associated with intravenous fentanyl administration. Coadministration of CBD and opioids was safe and well tolerated. These data provide the foundation for future studies examining CBD as a potential treatment for opioid abuse.

    Full Text Available [b]introduction and objective[/b]. Caffeine is one of the world’s most commonly ingested alkaloids which easily permeates the placenta. The teratogenic and embryotoxic influence of large doses of caffeine has been established in many experimental studies on animals. The objective of this work was to assess the influence of caffeine, administered at 45 °C, on the development of the bone tissue of rats, with particular reference to elemental bone composition using an X-ray microprobe. [b]materials and methods[/b]. The research was conducted on white rats of the Wistar strain. The fertilized females were divided into two groups: an Experimental Group (Group E and a Control Group (Group C. The females in Group E were given caffeine orally (at 45 °C in 30 mg/day doses from the 8 [sup]th [/sup] to the 21 [sup]st[/sup] day of pregnancy. The females in Group C were given water at the same temperature. The fetuses were used to assess the growth and mineralization of the skeleton. A qualitative analysis of the morphology and mineralization of bones was conducted using the alcian-alizarin method. For calcium and potassium analysis, an X-ray microprobe was used. [b]results.[/b] By staining the skeleton using the alcian-alizarin method, changes in 52 of Group E fetuses were observed. The frequency of the development variants in the Group E rats was statistically higher, compared with Group C. [b]conclusions[/b]. Receiving caffeine at a higher temperature may result in different pharmacodynamics and significantly change tolerance to it. In Group E, a significant decrease in the calcium level, as well as an increase in the potassium level, was observed. The X-ray microprobe can be a perfect complement to the methods which enable determination of the mineralization of osseous tissue.

    The primary objective of the current investigation was to establish the pharmacokinetic characteristics of oxymetazoline and tetracaine's primary metabolite, para-butylaminobenzoic acid (PBBA), after the intranasal administration of oxymetazoline/tetracaine. Thirty-six subjects contributing a total of 1791 plasma concentration results from 2 open-label trials were utilized. Model development was achieved using data from the second trial (N = 24) in which 0.3 mg oxymetazoline/18 mg tetracaine was administered. External model validation utilized data from the first trial (N = 12), which included doses of 0.3 mg oxymetazoline/18 mg tetracaine and 0.6 mg oxymetazoline/36 mg tetracaine. Oxymetazoline and PBBA dispositions were described by a 2-compartment model with first-order absorption. An allometric model for body weight was included on volumes and clearances to describe unexplained between-subject variability. The final oxymetazoline parameter estimates were k a 4.41 h -1 ; peripheral volume 418 L; clearance 66.4 L/h; central volume 6.97 L; and intercompartmental clearance 419 L/h for a 70-kg subject. The final PBBA parameter estimates were k a 8.51 h -1 ; peripheral volume 32.0 L; clearance 16.7 L/h; central volume 29.8 L; and intercompartmental clearance 2.43 L/h for a 70-kg subject. Between-subject variability ranged from 14% to 39% for oxymetazoline and from 10% to 94% for PBBA. © 2016, The American College of Clinical Pharmacology.

    To (1) evaluate the feasibility of touch screen depression screening in cancer patients using the Patient Health Questionnaire-9 (PHQ-9), (2) evaluate the construct validity of the PHQ-9 using the touch screen modality, and (3) examine the prevalence and severity of depression using this screening modality. The PHQ-9 was placed in a web-based survey within a study of the clinical impact of computerized symptom and quality of life screening. Patients in medical oncology, radiation oncology, and hematopoietic stem cell transplantation (HSCT) clinics used the program on a touch screen computer in waiting rooms prior to therapy (T1) and during therapy (T2). Responses of depressed mood or anhedonia (PHQ-2 cardinal depression symptoms) triggered additional items. PHQ-9 scores were provided to the oncology team in real time. Among 342 patients enrolled, 33 (9.6%) at T1 and 69 (20.2%) at T2 triggered the full PHQ-9 by endorsing at least one cardinal symptom. Feasibility was high, with at least 97% completing the PHQ-2 and at least 96% completing the PHQ-9 when triggered and a mean completion time of about 2 min. The PHQ-9 had good construct validity. Medical oncology patients had the highest percent of positive screens (12.9%) at T1, while HSCT patients had the highest percent (30.5%) at T2. Using this method, 21 (6.1%) at T1 and 54 (15.8%) at T2 of the total sample had moderate to severe depression. The PHQ-9 administered on a touch screen computer is feasible and provides valid depression data in a diverse cancer population. (c) 2008 John Wiley & Sons, Ltd.

    Conotruncal anomalies are often associated with abnormal coronary arteries. Although bis-diamine is known to induce conotruncal defects, its pathological effects on coronary vascular development have not been demonstrated. This study sought to assess the teratogenic effects of bis-diamine on coronary vascular development and the pathogenesis of this anomalous association. A single 200 mg dose of bis-diamine was administered to pregnant Wistar rats at 10.5 days of gestation. Fifty-two embryos from 10 mother rats underwent morphological analysis of the coronary arteries. Three embryos each were removed from four mothers on embryonic days (ED) 14.5, 15.5, 16.5, and 17.5 and used for immunohistochemical studies using the anti-vascular cell adhesion molecule (VCAM)-1 antibody. Conotruncal anomalies were detected in 48 of 52 embryos, and an aplastic or hypoplastic left coronary artery was found in all of them. In control embryos at ED 16.5, VCAM-1-positive epicardial cells were transformed into mesenchymal cells in vascular plexus, which appeared to differentiate into the endothelial cells of coronary vasculature. In the heart at ED 17.5, coronary vasculature was well developed and connected with coronary ostia near the aorta. However, poor epicardial-mesenchymal transformation and subsequent differentiation was revealed in bis-diamine-treated embryos at EDs 16.5 and 17.5, causing abnormal development of the coronary vasculature and incomplete connections with coronary ostia of the aorta. Anomalous coronary arteries in the bis-diamine-treated embryos are induced by the disruption of epicardial-mesenchymal transformation and subsequent poor development of coronary vasculature. Incomplete hatching of the coronary ostium is associated with abnormal truncal division. © 2010 Wiley-Liss, Inc.

    Background: The stage of youth is critical for human development in several ways. On the one hand, it can lead people towards the adoption of a healthy lifestyle during adulthood based on these earlier practices. On the other hand, it can comprise the development of healthy living practices later on in live, an outcome which is often caused by the youth adopting a risky lifestyle early on. Objectives: The primary objective of this study was to determine the effectiveness of implementing an educational intervention program based on the BASNEF Model (a simplified approach to understanding behavior), designed to cultivate self-administered lifestyle control skills in youths. Materials and Methods: This was a quasi-experimental intervention study, implemented during 2010 - 2011. A total of 288 randomly selected high-school students between the ages of 15 and 17 participated in this study. These students were later divided into experimental and control groups. Subjects completed a BASNEF questionnaire at the baseline (pre-test), one month later (post-test) and three months after the educational intervention (follow-up). Four educational sessions were held, each of a 120 - 150 minute duration. After the data had been collected, the ANOVA test was used to compare trends in changes. The Pearson correlation coefficient was then used to analyze the correlation between components of the BASNEF model. Finally, regression analysis was used to determine the predictive power of the study. Results: Results from the intervention study reveal that the beliefs and attitudes about nutrition of the intervention group, calculated in terms of scores, improved significantly for both male and female subjects (P eating habits and more active lifestyles at an early age in order to foster long-term health and well-being.

    Full Text Available Abstract Background To create and find accurate and reliable instruments for the measurement of physical activity has been a challenge in epidemiological studies. We investigated the reliability and validity of two different physical activity questionnaires in 71 adolescents aged 13–18 years; the WHO, Health Behaviour in Schoolchildren (HBSC questionnaire, and the International Physical Activity Questionnaire (IPAQ, short version. Methods The questionnaires were administered twice (8–12 days apart to measure reliability. Validity was assessed by comparing answers from the questionnaires with a cardiorespiratory fitness test (VO2peak and seven days activity monitoring with the ActiReg, an instrument measuring physical activity level (PAL and total energy expenditure (TEE. Results Intraclass correlation coefficients for reliability for the WHO HBSC questionnaire were 0.71 for frequency and 0.73 for duration. For the frequency question, there was a significant difference between genders; 0.87 for girls and 0.59 for boys (p 2peak were fair, ranging between 0.29 – 0.39. The WHO HBSC questionnaire measured against VO2peak for girls were acceptable, ranging between 0.30 – 0.55. Both questionnaires, except the walking question in IPAQ, showed a low correlation with PAL and TEE, ranging between 0.01 and 0.29. Conclusion These data indicate that the WHO HBSC questionnaire had substantial reliability and were acceptable instrument for measuring cardiorespiratory fitness, especially among girls. None of the questionnaires however seemed to be a valid instrument for measuring physical activity compared to TEE and PAL in adolescents.

    The objective of this study is to describe a disease management programme (DMP) for the bleeding disorder population insured by Indiana's high-risk insurance plan, and to assess the associated costs and outcomes. All bleeding disorder patients, covered by the state plan as their primary health insurance, were enrolled into a DMP administered by the Indiana Hemophilia & Thrombosis Center (IHTC). A pre/post-intervention study design was used, with 1-year pre-enrollment serving as the baseline period and 1-year post-enrollment as the study period. Claims data were used to assess hospitalizations, emergency room (ER) visits, total medical and clotting factor costs and factor units dispensed. Medical records were used to assess disease severity and other comorbidities. Thirty-one continuously enrolled patients had complete data over 2 years. Approximately 84% of the population was male, 81% with haemophilia. The average costs of care in the baseline year and the first year of the programme were $161 441 and $118 293, respectively. The decrease in the total costs was primarily attributed to a decrease in outpatient factor costs, which resulted from decreased factor utilization and lower per unit factor costs. The mean number of inpatient hospital days and ER visits for the DMP population decreased from 1.3 and 1.4 to 0.4 and 0.6, baseline and first year, respectively. Owing to the small sample size and high variability of the population, the differences were not statistically significant. The DMP appears to have reduced the total costs and resource utilization, although the study was underpowered.

    "The dose makes the poison", the common motto of toxicology first expressed by Paracelsus more than 400 years ago, may effectively serve to guide potential applications for metformin and related biguanides in oncology. While Paracelsus' law for the dose-response effect has been commonly exploited for the use of some anti-cancer drugs at lower doses in non-neoplastic diseases (e.g., methotrexate), the opposite scenario also holds true; in other words, higher doses of non-oncology drugs, such as anti-diabetic biguanides, might exert direct anti-neoplastic effects. Here, we propose that, as for any drug, there is a dose range for biguanides that is without any effect, one corresponding to "diabetobiguanides" with a pharmacological effect (e.g., insulin sensitization in type 2 diabetes, prevention of insulin-dependent carcinogenesis, indirect inhibition of insulin and growth factor-dependent cancer growth) but with minimal toxicity and another corresponding to "oncobiguanides" with pharmacological (i.e., direct and strong anticancer activity against cancer cells) as well as toxic effects. Considering that biguanides demonstrate a better safety profile than most oncology drugs in current use, we should contemplate the possibility of administering biguanides through non-conventional routes (e.g., inhaled for carcinomas of the lung, topical for skin cancers, intravenous as an adjunctive therapy, rectal suppositories for rectal cancer) to unambiguously investigate the therapeutic value of high-dose transient biguanide exposure in cancer. Perhaps then, the oncobiguanides, as we call them here, could be viewed as a mechanistically different type of anti-cancer drugs employed at doses notably higher than those used chronically when functioning as diabetobiguanides.

    This study evaluated the uptake of Western Australian (WA) pharmacist vaccination services, the profiles of consumers being vaccinated and the facilitators and challenges experienced by pharmacy staff in the preparation, implementation and delivery of services. Mixed-methods methodology with both quantitative and qualitative data through surveys, pharmacy computer records and immuniser pharmacist interviews. Community pharmacies in WA that provided pharmacist vaccination services between March and October 2015. Immuniser pharmacists from 86 pharmacies completed baseline surveys and 78 completed exit surveys; computer records from 57 pharmacies; 25 immuniser pharmacists were interviewed. Pharmacy and immuniser pharmacist profiles; pharmacist vaccination services provided and consumer profiles who accessed services. 15 621 influenza vaccinations were administered by immuniser pharmacists at 76 WA community pharmacies between March and October 2015. There were no major adverse events, and vaccinations under the National Immunisation Program but chose to have it at a pharmacy. A high percentage of vaccinations was delivered in rural and regional areas indicating that provision of pharmacist vaccination services facilitated access for rural and remote consumers. Immuniser pharmacists reported feeling confident in providing vaccination services and were of the opinion that services should be expanded to other vaccinations. Pharmacists also reported significant professional satisfaction in providing the service. All participating pharmacies intended to continue providing influenza vaccinations in 2016. This initial evaluation of WA pharmacist vaccination services showed that vaccine delivery was safe. Convenience and accessibility were important aspects in usage of services. There is scope to expand pharmacist vaccination services to other vaccines and younger children; however, government funding to pharmacists needs to be considered. Published by the BMJ Publishing

  16. Should unobstructed gasping be facilitated and confirmed before administering adrenaline, otherwise, give titrated vasopressin?

    2015-02-01

    A recent commentary, "Resuscitation That's (Un)Shockable: Time to Get the Adrenaline Flowing", published in the New England Journal of Medicine Journal Watch called attention to a relatively recent study showing that a large and increasing percentage of patients with in-hospital cardiac arrests exhibit initial nonshockable rhythms (asystole or pulseless electrical activity [PEA]; 82% in 2009 vs 69% in 2000) and a most recent study that concluded that neurologically intact survival to hospital discharge after in-hospital cardiac arrest was significantly more likely after earlier epinephrine administration. It was found that delayed administration of epinephrine was associated significantly with lower chance for survival to hospital discharge, in stepwise fashion (12%, 10%, 8%, and 7% survival, respectively, for patients receiving their first epinephrine dose≤3, 4-6, 7-9, and >9 minutes after arrest). Although early use of epinephrine to manage patients with nonshockable rhythms lacks strong evidence to support efficacy, focus on time to epinephrine administration-in addition to high-quality chest compressions-might be the best early intervention. However, evidence may strongly support the recommendation that adrenaline needs to be used very early because without effective-depth cardiopulmonary resuscitation (CPR) with complete recoil, epinephrine may only be effective when gasping is present, which is a time-limited phenomenon. However, because very few rescuers can perform effective-depth chest compressions with complete recoil, gasping is critically necessary for adequate ventilation and generation of adequate coronary and cerebral perfusion. However, under acidemic conditions and high catecholamine levels and/or absence of gasping, vasopressin should be administered instead. Published by Elsevier Inc.

    2013-01-01

    Background Food items on a self-administered food frequency questionnaire (FFQ) may be left blank because the food was not consumed, because of difficulties remembering the frequency or amount of intake, or due to an oversight. Methods We explored the predictors and frequency of consumption of omitted food items on an FFQ used in the Nurses’ Health Study II. Of 87,676 women who returned a mailed 147-item FFQ in 1999, 34% completed the entire questionnaire, whereas 66% left at least 1 food item blank. Ten or more foods were omitted by 5% of participants. Foods were more likely omitted by women who were older, more physically active, and had more children. We resurveyed 2876 participants who had left between 1 and 70 food items blank and asked them to fill in the blanks. Overall, 2485 participants provided complete responses. Results In the resurvey, 64% of the formerly omitted foods were marked as consumed never or less than once per month, 20% as 1–3 times per month, 8% as once per week, and 9% as more than once per week. Commonly consumed foods and beverages were less likely omitted because they were not consumed than rarely consumed foods. The best estimate for the true intake value of an omitted food was 0.82 times the average population intake. Conclusions When calculating nutrient intake, the assumption that items missing represent zero intake is reasonable. However, foods consumed more often in the population at large are less likely than rarely consumed foods to be left blank because they were not consumed. PMID:19106799

    Patients who have been administered radiopharmaceuticals become a source of exposure to a non-occupational individual helping in support and comfort of these patients. We measured external dose rates at several distances from 84 adult patients administered radiopharmaceuticals, and urinary excretion of radioactivity in their patients. And we estimated the maximal dose for persons having close contact with patients administered radiopharmaceuticals from the combination of these measurement data and scenarios of contact with patients. On the basis of the estimated values, we proposed the following dose constraint for care givers. (1) The dose constraint for a non-occupational care givers to an adult nuclear medicine patient should in no case exceed 300 μSv per patient per examination of any kind. (2) The dose constraint in ordinary examinations employing a radionuclide should not be greater than 15 μSv per patient per examination. (3 tabs.)

    Macroscopic liver lesions were investigated with the use of computed tomography (CT) and radionuclide imaging (RN) in 15 aplastic anemia patients who were administered anabolic steroids for over one year and who showed no apparent physical and biochemical sign of liver tumor. In 3 patients, CT scans showed radiolucent areas in the liver. Contrast enhancements revealed these lesions to be well vascularized, suggesting they were not cysts but probably tumors. RN imaging could not demonstrate any definite space occupying lesions. Total dose of AS administered to each of the three patients exceeded 30,000 mg. It was felt that attention should be paid to the possible development of hepatic tumor when the dose of AS administered exceeds 30,000 mg. (author)

    Telephone-administered psychotherapies (T-P) provided as an adjunct to antidepressant medication may improve response rates in major depressive disorder (MDD). The goal of this study was to compare telephone-administered social rhythm therapy (T-SRT) and telephone-administered intensive clinical management (T-ICM) as adjuncts to antidepressant medication for MDD. A secondary goal was to compare T-P with Treatment as Usual (TAU) as adjunctive treatment to medication for MDD. 221 adult out-patients with MDD, currently depressed, were randomly assigned to 8 sessions of weekly T-SRT (n=110) or T-ICM (n=111), administered as an adjunct to agomelatine. Both psychotherapies were administered entirely by telephone, by trained psychologists who were blind to other aspects of treatment. The 221 patients were a posteriori matched with 221 depressed outpatients receiving TAU (controls). The primary outcome measure was the percentage of responders at 8 weeks post-treatment. No significant differences were found between T-SRT and T-ICM. But T-P was associated with higher response rates (65.4% vs 54.8%, p=0.02) and a trend toward higher remission rates (33.2% vs 25.1%; p=0.06) compared to TAU. Short term study. This study is the first assessing the short-term effects of an add-on, brief, telephone-administered psychotherapy in depressed patients treated with antidepressant medication. Eight sessions of weekly telephone-delivered psychotherapy as an adjunct to antidepressant medication resulted in improved response rates relative to medication alone. Copyright © 2015 Elsevier B.V.

    Full Text Available The present study explored the effects of intranasal oxytocin, a naturally occurring hormone, on the behavior of pet dogs during an attachment test. Each dog participated in two testing sessions. On one visit saline was administered nasally, and on another, oxytocin was administered nasally. For half of the dogs (n = 20, solutions were administered with a Mucosal Atomization Device (MAD and for half of the dogs (n = 20, solutions were administered using a nasal spray bottle. Condition order was counterbalanced and a double-blind methodology was employed. Following a 30-min wait period after administration of solutions, dog-owner pairs participated in the Secure Base Test, a short attachment test consisting of three 2-min phases: (1 Baseline- the owner was present, dogs were able to freely explore the testing room (2 Alone- dogs were left alone in the testing room (3 Return- owners re-entered the room and were reunited with their dog. In each phase the dog was evaluated for contact seeking, exploration, and avoidance behaviors. Although, oxytocin administration was expected to increase owner-directed proximity and contact seeking behavior, this effect was not observed. In fact, in the baseline phase, dogs spent significantly more time seeking the proximity of their owners when they received saline than when they received OT (p < 0.05. Sex differences were also assessed for the behavioral variables of interest in the Secure Base Test, and results indicated that OT did not affect dogs' behavior in the alone phase, but when saline was administered, females spent significantly more time in contact with the door than males in the alone phase (p < 0.05. Overall, the effects of nasally administered oxytocin on attachment related behavior appeared to be limited or inconsistent for this pet dog population.

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. Purpose: This study evaluates the therapeutic effects of iontophoresis using GNPs and diclofenac diethylammonium on inflammatory parameters in rats challenged with traumatic tendinitis.Methods: 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 cm² electrodes. Results: 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 < 0.05. A significant decrease was observed in expression of cytokines interleukin 1 beta in the three treatment groups, in comparison with untreated challenged tendons, although, in the group treated with diclofenac and GNP, results were similar to the control (1.732 ± 239 (P < 0

    Health promotion and prevention services provided by the chiropractic profession historically have been referred to as maintenance care (MC). The primary objective of this investigation was to obtain information regarding multiple health issues of patients age 65 years and over who have had a long-term regimen of chiropractic health promotion and preventive care. The study also sought to explore the nature of the interventions and methods that were most commonly used by chiropractors when administering MC and to determine whether there were differences between patients who have had long-term exposure to these preventive services versus those who have not. This descriptive study was accomplished by selecting chiropractic patients (age 65 years and over) who had received health-promotion and prevention services for at least 5 years, with a minimum of 4 visits per year. To enhance the probability of securing a more representative patient sample, selection was made through the participation of chiropractors from 6 diverse geographic locations across the United States. Doctors were asked to enroll the first 10 consenting patients who met the inclusion criteria. A battery of diverse assessment instruments were completed by each patient to provide a patient health profile. Information related to each patient included answers to the SF-36D survey, patient health habits, expenditures of health services, frequency of use of health providers, and perceived value of chiropractic prevention and health promotion services. A total of 73 chiropractors participated in this investigation from the 6 study sites. In addition to an average 1.9 manual procedures used per patient, it was common to recommend stretching exercises (68.2%), aerobic exercises (55.6%), dietary advice (45.3%), and a host of other prevention strategies, including vitamins and relaxation. The patients investigated in this study reported making only half the annual number of visits to medical providers (4

    The continued success of community case management (CCM) programs in low-resource settings depends on the ability of these programs to retain the community health workers (CHWs), many of whom are volunteers, and maintain their high-quality performance. This study aims to identify factors related to the motivation and satisfaction of CHWs working in a malaria CCM program in two sub-counties in Western Kenya. We interviewed 70 CHWs who were trained to administer malaria rapid diagnostic tests as part of a broader study evaluating a malaria CCM program. We identified factors related to CHWs' motivation and their satisfaction with participation in the program, as well as the feasibility of program scale-up. We used principal components analysis to develop an overall CHW satisfaction score and assessed associations between this score and individual CHW characteristics as well as their experiences in the program. The majority of CHWs reported that they were motivated to perform their role in this malaria CCM program by a personal desire to help their community (69%). The most common challenge CHWs reported was a lack of community understanding about malaria diagnostic testing and CHWs' role in the program (39%). Most CHWs (89%) reported that their involvement in the diagnostic testing intervention had either a neutral or a net positive effect on their other CHW activities, including improving skills applicable to other tasks. CHWs who said they strongly agreed with the statement that their work with the malaria program was appreciated by the community had a 0.76 standard deviation (SD) increase in their overall satisfaction score (95% confidence interval CI = 0.10-1.24, P  = 0.03). Almost all CHWs (99%) strongly agreed that they wanted to continue their role in the malaria program. Overall, CHWs reported high satisfaction with their role in community-based malaria diagnosis, though they faced challenges primarily related to community understanding and

    Turmeric extract and turmeric oil have shown chemoprotective effect against chemically-induced malignancies in experimental animals. They can reverse precancerous changes in oral submucous fibrosis in humans. The use of turmeric or Curcuma longa Linn as a spice and household remedy has been known to be safe for centuries. In view of the long term administration required for cancer prevention a Phase I clinical trial of turmeric oil (TO) was designed to study the safety and tolerance of TO in volunteers for a period of 3 months. Nine healthy volunteers between 20 and 33 years of age were tested for haemoglobin, blood counts, liver and kidney functions, bleeding and clotting time and serum electrolytes initially and at 1 and 3 months of treatment. They were administered 0.6 ml of TO three times a day for 1 month and 1 ml in 3 divided doses for 2 months. The acute tolerability study on Day 1 was conducted in a Clinical Pharmacology daycare Unit. Blood pressure and pulse were recorded frequently on Day 1 and at 24, 48, 72 and 96 hours and fortnightly till 12 weeks. Volunteers were daily supervised for TO intake as well as for any side effects throughout the study period. Nine volunteers were enrolled for the study. One discontinued on 3rd day for allergic skin rashes which, on discontinuation of TO, gradually disappeared by two weeks. Another discontinued on 7th day for intercurrent fever requiring antibiotic treatment. Seven volunteers completed the study. There was no effect of TO, in two doses, on pulse and blood pressure and no side effects in acute tolerability study on Day 1. There was no effect of TO intake on weight, blood pressure, symptoms and signs upto 12 weeks. There was no clinical, haematological, renal or hepatic-toxicity of TO at 1 month and 3 months. Serum lipids did not show significant change except in one volunteer (reversible). In view of the potential for reversing oral submucous fibrosis, a precancerous condition for oral cancer, TO, can be

    Highlights: ► There is rising concern regarding the potential health risks of nanomaterials. ► Few studies have investigated the effect of nanomaterials on the reproductive system. ► Here, we evaluated the intra-testicular distribution of nanosilica particles. ► We showed that nanosilica particles can penetrate the blood-testis barrier. ► These data provide basic information on ways to create safer nanomaterials. -- Abstract: Amorphous nanosilica particles (nSP) are being utilized in an increasing number of applications such as medicine, cosmetics, and foods. The reduction of the particle size to the nanoscale not only provides benefits to diverse scientific fields but also poses potential risks. Several reports have described the in vivo and in vitro toxicity of nSP, but few studies have examined their effects on the male reproductive system. The aim of this study was to evaluate the testicular distribution and histologic effects of systemically administered nSP. Mice were injected intravenously with nSP with diameters of 70 nm (nSP70) or conventional microsilica particles with diameters of 300 nm (nSP300) on two consecutive days. The intratesticular distribution of these particles 24 h after the second injection was analyzed by transmission electron microscopy. nSP70 were detected within sertoli cells and spermatocytes, including in the nuclei of spermatocytes. No nSP300 were observed in the testis. Next, mice were injected intravenously with 0.4 or 0.8 mg nSP70 every other day for a total of four administrations. Testes were harvested 48 h and 1 week after the last injection and stained with hematoxylin–eosin for histologic analysis. Histologic findings in the testes of nSP70-treated mice did not differ from those of control mice. Taken together, our results suggest that nSP70 can penetrate the blood-testis barrier and the nuclear membranes of spermatocytes without producing apparent testicular injury.

    Full Text Available Nanoparticles (NPs are increasingly being used for drug delivery, as well as antigen carriers and immunostimulants for the purpose of developing vaccines. In this work, we examined how intranasal (i.n. priming followed by i.n. or subcutaneous (s.c. boosting immunization affects the humoral immune response to chicken ovalbumin (Ova and Ova conjugated to 20 nm NPs (NP-Ova. We show that i.n. priming with 20 mg of soluble Ova, a dose known to trigger oral tolerance when administered via gastric gavage, induced substantial systemic IgG1 and IgG2c, as well as mucosal antibodies. These responses were further boosted following a s.c. immunization with Ova and complete Freund’s adjuvant (Ova+CFA. In contrast, 100 µg of Ova delivered via NPs induced an IgG1-dominated systemic response, and primed the intestinal mucosa for secretion of IgA. Following a secondary s.c. or i.n. immunization with Ova+CFA or NP-Ova, systemic IgG1 titers significantly increased, and serum IgG2c and intestinal antibodies were induced in mice primed nasally with NP-Ova. Only Ova- and NP-Ova-primed mice that were s.c.-boosted exhibited substantial systemic and mucosal titers for up to 6 months after priming, whereas the antibodies of i.n.-boosted mice declined over time. Our results indicate that although the amount of Ova delivered by NPs was 1000-fold less than Ova delivered in soluble form, the antigen-specific antibody responses, both systemic and mucosal, are essentially identical by 6 months following the initial priming immunization. Additionally, both i.n.- and s.c.-boosting strategies for NP-Ova-primed mice were capable of inducing a polarized Th1/Th2 immune response, as well as intestinal antibodies; however, it is only by using a heterogeneous prime-boost strategy that long-lasting antibody responses were initiated. These results provide valuable insight for future mucosal vaccine development, as well as furthering our understanding of mucosal antibody responses.

    Full Text Available Abstract Background Common dental procedures induce bacteremia. To prevent infectious complications from bacteremia in patients with specific medical conditions, antibiotic prophylaxis is considered. Recommendations are often unclear and ambiguous. In a previous study we reported wide variations in general dental practitioners' (GDPs' administrations of antibiotic prophylaxis. We hypothesized that within such a conflicting clinical area, decisions are made with a high level of personal uncertainty. This study examined GDPs' confidence in their decisions and analyzed the extent to which case-related factors might explain individual variations in confidence. Methods Postal questionnaires in combination with telephone interviews were used. The response rate was 51% (101/200. There were no significant differences between respondents and non-respondents regarding sex, age, or place of work. The GDPs were presented to patient cases of different medical conditions, where some should receive antibiotic prophylaxis according to recommendations when performing dental procedures that could cause gingival bleeding. The GDPs assessed on visual analogue scales how confident they were in their decisions. The extent to which case-related factors, medical condition and dental procedure, could explain individual variation in confidence was analyzed. Results Overall the GDPs exhibited high confidence in their decisions regardless of whether they administered antibiotic prophylaxis or not, or whether their decisions were in accordance with recommendations or not. The case-related factors could explain between 30–100% of the individual variation in GDPs' confidence. For 46%, the medical condition significantly explained the individual variation in confidence. However, for most of these GDPs, lower confidence was not presented for conditions where recommendations are unclear and higher confidence was not presented for conditions where recommendations are more clear

    1971-08-01

    In order to determine the effect of radiation on the structure of native shortgrass plains vegetation, an 8750 Ci 137Cs source was installed on the Central Plains Experimental Range near Nunn, Colorado; The experimental area was divided into 6 treatment sectors, a control, 2 sectors for chronic exposure (irradiation initiated April 1969 and continuing as of August 1971), and one each for spring, summer and late fall seasonal semi-acute (30 day), exposures which were administered during April, July and December, 1969, respectively. Community structure was measured by coefficient of community and diversity index. Yield was determined by clipping plots in September 1970 and visual estimates in September 1969 and 1970 for the grass-sedge component of the vegetation. Individual species sensitivity was determined by density data recorded in April, June and September of 1969 and 1970 and by a phenological index recorded at weekly intervals during the 1969 and 1970 growing seasons. The response of the vegetation was similar whether determined by coefficient of community or diversity with diversity being a more sensitive measure of effects. In the chronically exposed sectors, the exposure rate which resulted in a 50 per cent reduction in these 2 parameters (CC50 or D50) was still decreasing the second growing season and was approximately 18 R/hr for the CC50 as of June 1970 and 10 R/hr for the D50 as of September 1970. For the seasonally exposed sectors, the late fall period (December, 1969) was the most sensitive, summer (July, 1969) the least sensitive and spring (April, 1969) intermediate with CC50 and D50 values of 195 and 90, 240 and 222, and 120 and 74 R/hr for the spring, summer and late fall exposed sectors, respectively. Yield and density data indicated a rapid revegetation of the spring and summer exposed sectors during 1970 as a result of an influx of invader species such as Salsola kali tenuifolia, Chenopodium leptophyllum and Lepidium densiflorum and the

    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

    The present study explored the effects of intranasal oxytocin, a naturally occurring hormone, on the behavior of pet dogs during an attachment test. Each dog participated in two testing sessions. On one visit saline was administered nasally, and on another, oxytocin was administered nasally. For half of the dogs ( n = 20), solutions were administered with a Mucosal Atomization Device (MAD) and for half of the dogs ( n = 20), solutions were administered using a nasal spray bottle. Condition order was counterbalanced and a double-blind methodology was employed. Following a 30-min wait period after administration of solutions, dog-owner pairs participated in the Secure Base Test, a short attachment test consisting of three 2-min phases: (1) Baseline- the owner was present, dogs were able to freely explore the testing room (2) Alone- dogs were left alone in the testing room (3) Return- owners re-entered the room and were reunited with their dog. In each phase the dog was evaluated for contact seeking, exploration, and avoidance behaviors. Although, oxytocin administration was expected to increase owner-directed proximity and contact seeking behavior, this effect was not observed. In fact, in the baseline phase, dogs spent significantly more time seeking the proximity of their owners when they received saline than when they received OT ( p females spent significantly more time in contact with the door than males in the alone phase ( p oxytocin on attachment related behavior appeared to be limited or inconsistent for this pet dog population.

    2013-04-01

    To determine whether administration of meloxicam or acetylsalicylic acid alters glomerular filtration rate (GFR) in cats with renal azotemia. 6 young adult cats. 3 sexually intact male cats and 3 sexually intact female cats had surgically reduced renal mass and azotemia comparable to International Renal Interest Society chronic kidney disease stages 2 and 3. Renal function was evaluated by measurement of serum creatinine concentration, urinary clearance of exogenously administered creatinine, and the urine protein-to-creatinine concentration ratio (UP:C). Measurements taken in cats receiving placebo at the beginning and end of the study were compared with results obtained at the end of 7 days of treatment with either meloxicam (0.2 mg/kg, SC, on day 1; 0.1 mg/kg, SC, on days 2 to 7) or acetylsalicylic acid (20 mg/kg, PO, on days 1, 4, and 7). No significant treatment effects on urinary clearance of exogenously administered creatinine, serum creatinine concentration, or UP:C were detected. Mean ± SEM serum creatinine concentration and urinary clearance of exogenously administered creatinine measurements following 7 days of treatment with meloxicam (serum creatinine concentration, 2.67 ± 0.17 mg/dL; urinary clearance of exogenously administered creatinine, 1.34 ± 0.08 mL/min/kg) and acetylsalicylic acid (serum creatinine concentration, 2.62 ± 0.12 mg/dL; urinary clearance of exogenously administered creatinine, 1.35 ± 0.07 mL/min/kg) were not significantly different from the mean baseline values for these variables (serum creatinine concentration, 2.77 ± 0.14 mg/dL; urinary clearance of exogenously administered creatinine, 1.36 ± 0.07 mL/min/kg). Neither meloxicam nor acetylsalicylic acid had a measurable effect on urinary clearance of exogenously administered creatinine, serum creatinine concentration, or UP:C. These results are consistent with the hypothesis that GFR of euvolemic cats with normal or reduced renal function is not dependent on cyclooxygenase

  6. Authority of Pharmacists to Administer Human Papillomavirus Vaccine: Alignment of State Laws With Age-Level Recommendations.

    Science.gov (United States)

    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.

    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.

    1982-01-01

    Equations are given for calculating the dose to the surface of the bladder wall for any values of the parameters, urine flow-rate, bladder voiding period and initial content, for any administered radiopharmaceutical with known biokinetics. The necessary relationships which describe the variation in dose to the bladder wall per unit of cumulated activity in contents with increasing volume of contents are given for 31 radionuclides. Two commonly used renal radiopharmaceuticals, 131 I Hippuran and 99 Tcsup(m) DTPA, are used to illustrate the effects of the above three physiological variables on the dose to the bladder wall and it may be concluded that, for radiopharmaceuticals which are rapidly transferred to the bladder, substantial dose reduction can be achieved by optimising these parameters. Thus, where possible, the patient should be well hydrated, the radiopharmaceutical should be administered when the bladder is partly filled and the voiding period should be about 1.5 h. (author)

    The optimization of medical exposure is one of the major issues regarding radiation protection in the world, and The International Committee of Radiological Protection and the International Atomic Energy Agency recommend establishing diagnostic reference levels (DRLs) as tools for dose optimization. Therefore, the development of DRLs based on the latest survey has been required for nuclear medicine-related societies and organizations. This prompted us to conduct a nationwide survey on the actual administered radioactivity to adults for the purpose of developing DRLs in nuclear medicine. A nationwide survey was conducted from November 25, 2014 to January 16, 2015. The questionnaire was sent to all of the 1249 nuclear medicine facilities in Japan, and the responses were collected on a website using an answered form. Responses were obtained from 516 facilities, for a response rate of 41 %. 75th percentile of (99m)Tc-MDP and (99m)Tc-HMDP: bone scintigraphy, (99m)Tc-HM-PAO, (99m)Tc-ECD and (123)I-IMP: cerebral blood flow scintigraphy, (99m)Tc-Tetrofosmin, (99m)Tc-MIBI and (201)Tl-Cl; myocardial perfusion scintigraphy and (18)F-FDG: oncology PET (in-house-produced or delivery) in representative diagnostic nuclear medicine scans were 932, 937, 763, 775, 200, 831, 818, 180, 235 and 252, respectively. More than 90 % of the facilities were within the range of 50 % from the median of these survey results in representative diagnostic nuclear medicine facilities in Japan. Responses of the administered radioactivities recommended by the package insert, texts and guidelines such as 740 MBq ((99m)Tc-MDP and (99m)Tc-HMDP: bone scintigraphy), 740 MBq ((99m)Tc-ECD and (99m)Tc-HM-PAO: cerebral blood flow scintigraphy) and 740 MBq ((99m)Tc-Tetrofosmin and (99m)Tc-MIBI: myocardial perfusion scintigraphy), etc. were numerous.

    Glutathione (GSH), a cysteine-containing tripeptide, functions as an antioxidant, provides cells with cysteine, and is required for optimal function of the immune system. Because the epithelial-lining fluid (ELF) of the lower respiratory tract normally contains high GSH levels and lung ELF GSH deficiency states can exist, we evaluated the feasibility of augmenting lung ELF GSH levels by (i) administering GSH to sheep i.v. and by direct aerosolization and then (ii) measuring the GSH levels in lung ELF, lung lymph, venous plasma, and urine. When GSH (600 mg) was administered i.v. (n = 11), GSH levels in venous plasma, lung lymph, and ELF rose, but only transiently, suggesting the i.v. route would not deliver adequate GSH to the alveolar epithelial surface. For directly administering GSH to the lung by the aerosol route, in vitro studies were first conducted to show that greater than 50% of a GSH solution could be converted to droplets less than 3 microns in aerodynamic diameter without oxidizing the GSH. To target functional GSH to the lower respiratory tract, an aerosolized solution of GSH (600 mg) was administered to sheep (n = 12). Significantly, the GSH level in ELF increased 7-fold at 30 min (preaerosol, 45.7 +/- 10 microM; 30-min postaerosol, 337 +/- 64 microM; P less than 0.001). The ELF GSH levels remained above baseline at 1 hr (P less than 0.01), returning toward baseline over a 2-hr period. In contrast, GSH levels in lung lymph, venous plasma, and urine were not significantly increased during the period--i.e., aerosol therapy selectively augmented the GSH levels only at the lung epithelial surface. Thus, functional GSH can be delivered by aerosol to directly augment the ELF GSH levels of the lower respiratory tract. Such an approach may prove useful in treating a variety of lung disorders.

    Full Text Available The administration of biological compounds that optimize health benefits is an ever-evolving therapeutic goal. Pharmaceutical and other adjunctive biological compounds have been administered via many different routes in order to produce a systemic pharmacological effect. The article summarizes the findings from an Australian comparative study in adults administered vitamin B12 through different oral delivery platforms. A total of 16 subjects (9 males, 7 females voluntarily partook in a comparative clinical study of five different vitamin B12 formulations across a six-month period, completing 474 person-hours of cumulative contribution, that was equivalent to an n = 60 participation. A nanoparticle delivered vitamin B12 through a NanoCelle platform was observed to be significantly (p < 0.05 better absorbed than all other dose equivalent platforms (i.e., tablets, emulsions, or liposomes from baseline to 1, 3, and 6 h of the study period. The nanoparticle platform delivered vitamin B12 demonstrated an enhanced and significant absorption profile as exemplified by rapid systemic detection (i.e., 1 h from baseline when administered to the oro-buccal mucosa with no reports of any adverse events of toxicity. The nanoparticle formulation of methylcobalamin (1000 µg/dose in 0.3 mL volume showed bioequivalence only with a chewable-dissolvable tablet that administered a five times higher dose of methylcobalamin (5000 µg per tablet. This study has demonstrated that an active metabolite embedded in a functional biomaterial (NanoCelle may constitute a drug delivery method that can better access the circulatory system.

    This single-case, mixed-method study explored the feasibility of self-administered, home-based SMART (sensorimotor active rehabilitation training) Arm training for a 57-yr-old man with severe upper-limb disability after a right frontoparietal hemorrhagic stroke 9 mo earlier. Over 4 wk of self-administered, home-based SMART Arm training, the participant completed 2,100 repetitions unassisted. His wife provided support for equipment set-up and training progressions. Clinically meaningful improvements in arm impairment (strength), activity (arm and hand tasks), and participation (use of arm in everyday tasks) occurred after training (at 4 wk) and at follow-up (at 16 wk). Areas for refinement of SMART Arm training derived from thematic analysis of the participant's and researchers' journals focused on enabling independence, ensuring home and user friendliness, maintaining the motivation to persevere, progressing toward everyday tasks, and integrating practice into daily routine. These findings suggest that further investigation of self-administered, home-based SMART Arm training is warranted for people with stroke who have severe upper-limb disability.

    Dietary fiber by definition is resistant to digestion and absorption in the human small intestine, and it should naturally reach the large intestine. To date, there have been several reports that have examined in vivo how much dietary fiber actually reaches the terminal ileum in human subjects using glucose, with large differences in results. We compared the amount of pectin in the human terminal ileum with that of orally administered pectin. Seven healthy male volunteers ages 20 to 27 y were given a test meal containing 4.05 g of pectin. A double-lumen tube was placed in the terminal ileum by using the endoscopic retrograde bowel insertion method, and the ileal contents were aspirated through the tube. Amounts of pectin orally administered and collected from the terminal ileum were estimated as galacturonic acid concentrations (Englyst's method) and were compared with each other. The mean +/- standard deviation amount of pectin collected in the terminal ileum was 3.58 +/- 0.43 g, or 88.4 +/- 10.5% of pectin administered. Further, there were large individual differences in recovery, ranging from 76.8% to 105.1%. Approximately 90% of ingested pectin was recovered in the terminal ileum in this study. Ten percent may have been degraded by bacteria within the digestive tract, especially the terminal ileum.

  18. Self-administered nicotine differentially impacts body weight gain in obesity-prone and obesity-resistant rats.

    2017-07-01

    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.

The primary cause for the most common form of HAE is a deficiency in functional C1 esterase inhibitor (C1-INH. The swelling caused by HAE can be painful, disfiguring, and life-threatening. It reduces daily function and compromises the quality of life of affected individuals and their caregivers. Among different treatment strategies, replacement with C1-INH concentrates is employed for on-demand treatment of acute attacks and long-term prophylaxis. Three human plasma-derived C1-INH preparations are approved for HAE treatment in the US, the European Union, or both regions: Cinryze®, Berinert®, and Cetor®; however, only Cinryze is approved for long-term prophylaxis. Postmarketing studies have shown that home therapy (self-administered or administered by a caregiver is a convenient and safe option preferred by many HAE patients. In this review, we summarize the role of self-administered plasma-derived C1-INH concentrate therapy with Cinryze at home in the prophylaxis of HAE. Keywords: C1-INH concentrate, hereditary angioedema, disease management, first line, prophylaxis, self-administration

    To develop a self-administered cognitive assessment instrument to facilitate the screening of mild cognitive impairment (MCI) and early dementia and determine its association with gold standard clinical assessments including neuropsychologic evaluation. Adults aged above 59 years with sufficient vision and English literacy were recruited from geriatric and memory disorder clinics, educational talks, independent living facilities, senior centers, and memory screens. After Self-administered Gerocognitive Examination (SAGE) screening, subjects were randomly selected to complete a clinical evaluation, neurologic examination, neuropsychologic battery, functional assessment, and mini-mental state examination (MMSE). Subjects were identified as dementia, MCI, or normal based on standard clinical criteria and neuropsychologic testing. Two hundred fifty-four participants took the SAGE screen and 63 subjects completed the extensive evaluation (21 normal, 21 MCI, and 21 dementia subjects). Spearman rank correlation between SAGE and neuropsychologic battery was 0.84 (0.76 for MMSE). SAGE receiver operating characteristics on the basis of clinical diagnosis showed 95% specificity (90% for MMSE) and 79% sensitivity (71% for MMSE) in detecting those with cognitive impairment from normal subjects. This study suggests that SAGE is a reliable instrument for detecting cognitive impairment and compares favorably with the MMSE. The self-administered feature may promote cognitive testing by busy clinicians prompting earlier diagnosis and treatment.

    To provide information relevant to decision-making around the timing of attempting the centrally administered summative assessments in the Royal Australian and New Zealand College of Psychiatrists (RANZCP) 2012 Fellowship Program. We consider the new Competency-Based Fellowship Program of the RANZCP and its underlying philosophy, the trainee trajectory within the program and the role of the supervisor. The relationship between workplace-based and external assessments is discussed. The timing of attempting centrally administered summative assessments is considered within the pedagogical framework of medical competencies development. Although successful completion of all the centrally administered summative assessments requires demonstration of a junior consultant standard of competency, the timing at which this standard will most commonly be achieved is likely to vary from assessment to assessment. There are disadvantages attendant upon prematurely attempting assessments, and trainees are advised to carefully consider the requirements of each assessment and match this against their current level of knowledge and skills. Trainees and supervisors need to be clear about the competencies required for each of the external assessments and match this against the trainee's current competencies to assist in decision-making about the timing of assessments and planning for future learning. © The Royal Australian and New Zealand College of Psychiatrists 2016.

    The in vivo situation of the Aescin, a product of aesculus hippocastanum, was examined by administering the 3 H labelled compounds to rats. The following results were obtained: 1) The intestinal absorption from oral administration was not so fast. The blood concentration was low, and its combination with plasma protein was slight. 2) As for the distribution in the organs after an oral administration, the affinity was relatively high in the following organs: Pancreas>heart>kidney>adrenal>gland>lung>muscle>liver. However, the concentrations were extremely low being shown by a ng unit per g tissue in the organs. 3) When it was administered orally to the pregnant rats, the concentrations which were transmitted to the fetuses were low. 4) On the 7th day after oral administration, excretion into the urine was less than 3% and in the feces was more than 70%. The bile excretion was also observed. 5) The metabolic products in the excretion after the oral administration were examined by the method. A large amount of Aescin was excreted in an unchanged form or in compounds. From this, Aescin is presumed to be metabolised by the activity of intestinal bacterial enzymes. 6) The absorption of this drug into the body was low when it was intracutaneously administered.

    To describe the variety of medications prescribed along with the doses administered and routes of administration, and to delineate the clarity of orders written and the accuracy of transcription of drugs used for sedation, anxiety, pain, and neuromuscular blockade in a surgical intensive care unit (ICU). A prospective, observational study of drug-related information collected from forms used by physicians and nurses. Three adult surgical ICUs at an academic medical center. Patients were admitted to a surgical service and co-managed by the surgical ICU team and primary surgical service. Consecutive patients admitted to all of these units from September 1992 to January 1993. None. Information on prescribing and administering sedatives, analgesics, and neuromuscular blocking drugs was obtained from data collected on 221 patients. A total of 202 (91%) patients received, on average, 1.9 +/- 1.4 study drugs (range 0 to 9) in a wide variety of combinations. There were 2,103 total doses administered from 448 drug orders. Ninety percent of study drug orders were written for administration on an "as-needed" basis; in 42% of these orders, the indication for use was not specified. On average, only 27% of the maximal allowable daily dose was administered; this number ranged from 15% for hydromorphone to 77% for chlordiazepoxide. Morphine sulfate, the most commonly prescribed drug, was ordered primarily for intravenous administration in 84% of patients. Morphine sulfate was prescribed using 19 different doses (written as a range of doses) and 13 different dosing intervals. Transcription discrepancies were observed in 17% of orders. In 2.7% of doses, the actual dose that was administered could not be determined. A wide variety of sedatives and analgesics are frequently used in surgical ICU patients. These agents are often ordered on an "as-needed" basis using a range of doses, sometimes without adequate directions about the indication for their use. Daily doses received are

    Full Text Available 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.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.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 (rs = 0.30 and interviewer-administration (rs = 0.46. Findings were similar when considering 10-min activity bouts in the accelerometer analysis for MVPA (rs = 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 (rs = 0.61 vs. 0.63 for self vs. interviewer

    Nuclear medicine in Argentine is carried out at 292 centres, distributed all over the country, mainly concentrated in the capital cities of the provinces. With the purpose of knowing the activity levels of radiopharmaceuticals that were administered to patients for diagnostic and therapeutic procedures in nuclear medicine, a national survey was conducted, during 2001 and 2002. This survey was answered voluntarily by 107 centres. Sixty-four percent of the participants centres are equipped with SPECT system while the other centres have a gamma camera or scintiscanner. There were 37 nuclear medicine procedures, chosen among those most frequently performed, were included in the survey. In those diagnostic procedures were included tests for: bone, brain, thyroid, kidney, liver, lung and cardiovascular system; and also activities administered for some therapeutic procedures. The nuclear medicine physicians reported the different radiopharmaceutical activities administered to typical adult patients. In this paper are presented the average radiopharmaceutical activity administered for each of the diagnostic and therapeutic procedures included in the survey and the range and distribution of values. In order to place these data in a frame of reference, these average values were compared to the guidance levels for diagnostic procedures in nuclear medicine mentioned at the Safety Series no. 115. From this comparison it was noticed that the activities administered in the 40% of the diagnostic procedures included in the survey were between ±30% of the reference values. For those nuclear medicine procedures that could not be compared with the above mentioned guidance levels, the comparison was made with values published by UNSCEAR or standards recommended by international bodies. As a result of this study, it is important to point out the need to continue the gathering of data in a wider scale survey to increase the knowledge about national trends. It is also essential to widely

    The objective of this study was to evaluate the psychological profile of craniofacial pain sufferers and the impact of patient subtype classification on the short-time effectiveness of a self-administered relaxation training. One hundred unselected in-office patients (67% females) suffering from chronic facial pain and/or headache with the presumptive diagnose of temporo-mandibular disorder (TMD) completed a questionnaire battery comprising craniofacial pain perception, somatic complaints, irrational beliefs, and pain behavior and were classified into subtypes using cluster analysis. They underwent a self-administered progressive relaxation training and were re-evaluated for pain perception after 3 months. Pain was mild to moderate in the majority of patients. Symptom domains comprised parafunctional activities, temporo-mandibular pain and dysfunction, fronto-temporal headache, head/neck and neck/back pain. Three patient subtypes were identified regarding symptom/dysfunction level: (i) low burden (mild/moderate), (ii) psychosocial dysfunction (moderate/high), (iii) adaptive coping (moderate/mild). Self-rated adherence to the recommended relaxation training was moderate throughout the sample, but self-rated relief was significantly different between clusters. At follow-up, pain intensity was significantly decreased in all patients, whereas pain-related interference was improved only in dysfunctional and adaptive patients. Improvement of symptom domains varied between clusters and was most comprehensive in adaptive patients. In conclusion, craniofacial pain sufferers can be divided in meaningful subtypes based on their pain perception, irrational beliefs, and pain behaviour. A self-administered relaxation training generally yielded positive effects on pain perception, however the benefit may be greater in patients with more marked symptom impact (both dysfunctional and adaptive).

    The aim of this study was to develop a self-administered dementia checklist (SDC), in order to help community-residing older adults realize their declining functions and encourage them to begin using necessary services, and to examine its factorial validity and internal reliability. A panel of dementia clinical experts developed a questionnaire according to pre-selected items and conducted a self-administered survey with community-residing people aged 65 + (n=2,483). The team developed a scale through an exploratory factor analysis and item response theory (IRT) analysis (Study 1). Using this scale, they conducted a self-administered survey with community-residing people aged 65 + (n=5,199), conducted another exploratory factor analysis, and developed a 10-item scale. A confirmatory factor analysis was subsequently conducted and reliability coefficients were computed. The exploratory factor analysis of the proposed 37 items extracted 5 factors: Factor 1 was named "subjective decline in daily living functioning," and Factor 2 was "subjective cognitive decline" in the early stage of dementia. The team developed a 20-item scale by selecting 10 items from each factor which had high factor loadings and high slope values in the IRT analysis (Study 1). After the exploratory factor analysis of the 20-item scale, they developed a 10-item scale by selecting 5 items from each factor which had strong associations. The confirmatory factor analysis verified the 2-factor model. The Cronbach α coefficients for the subscales of Factors 1 and 2 were 0.935 and 0.834, respectively, and 0.908 for the overall 10-item scale. The authors developed a 10-item SDC with 2 factors and confirmed its factorial validity and internal reliability.

    In an environment of limited health care resources, it is crucial for health care systems which provide blood transfusion to have accurate and comprehensive information on the costs of transfusion, incorporating not only the costs of blood products, but also their administration. Unfortunately, in many countries accurate costs for administering blood are not available. Our study aimed to generate comprehensive estimates of the costs of administering transfusions for the UK National Health Service. A detailed microcosting study was used to cost two key inputs into transfusion: transfusion laboratory and nursing inputs. For each input, data collection forms were developed to capture staff time, equipment, and consumables associated with each step in the transfusion process. Costing results were combined with costs of blood product wastage to calculate the cost per unit transfused, separately for different blood products. Data were collected in 2014/15 British pounds and converted to US dollars. A total of 438 data collection forms were completed by 74 staff. The cost of administering blood was $71 (£49) per unit for red blood cells, $84 (£58) for platelets, $55 (£38) for fresh-frozen plasma, and $72 (£49) for cryoprecipitate. Blood administration costs add substantially to the costs of the blood products themselves. These are frequently incurred costs; applying estimates to the blood components supplied to UK hospitals in 2015, the annual cost of blood administration, excluding blood products, exceeds $175 (£120) million. These results provide more accurate estimates of the total costs of transfusion than those previously available. © 2018 AABB.

    Full Text Available OBJECTIVE: To assess the cost effectiveness of giving tranexamic acid (TXA to bleeding trauma patients in low, middle and high income settings. METHODS: The CRASH-2 trial showed that TXA administration reduces the risk of death in bleeding trauma patients with a small but statistically significant increase in non-intensive care stay. A Markov model was used to assess the cost effectiveness of TXA in Tanzania, India and the United Kingdom (UK. The health outcome was the number of life years gained (LYs. Two costs were considered: the cost of administering TXA and the cost of additional days in hospital. Cost data were obtained from hospitals, World Health Organization (WHO database and UK reference costs. Cost-effectiveness was measured in international dollars ($ per LY. Both deterministic and probabilistic sensitivity analyses were performed to test the robustness of the results to model assumptions. FINDINGS: Administering TXA to bleeding trauma patients within three hours of injury saved an estimated 372, 315 and 755 LYs per 1,000 trauma patients in Tanzania, India and the UK respectively. The cost of giving TXA to 1,000 patients was $17,483 in Tanzania, $19,550 in India and $30,830 in the UK. The incremental cost of giving TXA versus not giving TXA was $18,025 in Tanzania, $20,670 in India and $48,002 in the UK. The estimated incremental cost per LY gained of administering TXA is $48, $66 and $64 in Tanzania, India and the UK respectively. CONCLUSION: Early administration of TXA to bleeding trauma patients is likely to be highly cost effective in low, middle and high income settings.

    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.

    2014-01-01

    Introduction Coordination of the tasks of performing chest compressions and defibrillation can lead to communication challenges that may prolong time spent off the chest. The purpose of this study was to determine whether defibrillation provided by the provider performing chest compressions led to a decrease in peri-shock pauses as compared to defibrillation administered by a second provider, in a simulated cardiac arrest scenario. Methods This was a randomized, controlled study measuring pauses in chest compressions for defibrillation in a simulated cardiac arrest model. We approached hospital providers with current CPR certification for participation between July, 2011 and October, 2011. Volunteers were randomized to control (facilitator-administered defibrillation) or experimental (compressor-administered defibrillation) groups. All participants completed one minute of chest compressions on a mannequin in a shockable rhythm prior to administration of defibrillation. We measured and compared pauses for defibrillation in both groups. Results Out of 200 total participants, we analyzed data from 197 defibrillations. Compressor-initiated defibrillation resulted in a significantly lower pre-shock hands-off time (0.57 s; 95% CI: 0.47–0.67) compared to facilitator-initiated defibrillation (1.49 s; 95% CI: 1.35–1.64). Furthermore, compressor-initiated defibrillation resulted in a significantly lower peri-shock hands-off time (2.77 s; 95% CI: 2.58–2.95) compared to facilitator-initiated defibrillation (4.25 s; 95% CI: 4.08–4.43). Conclusion Assigning the responsibility for shock delivery to the provider performing compressions encourages continuous compressions throughout the charging period and decreases total time spent off the chest. However, as this was a simulation-based study, clinical implementation is necessary to further evaluate these potential benefits. PMID:24672620

    To evaluate the efficacy and safety of twice-daily difluprednate ophthalmic emulsion 0.05% (Durezol(®)) versus placebo administered before surgery for managing inflammation and pain following cataract extraction. Eligible subjects (N = 121) were randomized 2:1 to topical treatment with 1 drop difluprednate or placebo administered twice daily for 16 days, followed by a 14-day tapering period. Dosing was initiated 24 hours before unilateral ocular surgery. Clinical signs of inflammation (anterior chamber [AC] cell and flare grade, bulbar conjunctival injection, ciliary injection, corneal edema, and chemosis), ocular pain/discomfort, intraocular pressure (IOP), and adverse events were assessed. Clearing of inflammation on day 14 (primary endpoint), defined as an AC cell grade of 0 (≤5 cells) and a flare grade of 0 (complete absence), was achieved in a significantly greater percentage of subjects treated with difluprednate, compared with placebo (74.7% vs 42.5%; P = 0.0006). A significantly greater percentage of difluprednate-treated subjects were free of ocular pain/discomfort on day 14 than placebo-treated subjects (64.6% vs 30.0%; P = 0.0004). Three subjects (3.7%) in the difluprednate group had a clinically significant IOP rise (defined as ≥21 mmHg and a change from baseline ≥10 mmHg at same visit). Difluprednate, administered 2 times daily starting 24 hours before cataract surgery, was highly effective for managing ocular inflammation and relieving pain and discomfort postoperatively. Difluprednate was well tolerated and provides a convenient twice-daily option for managing postoperative ocular inflammation.

    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.

    PURPOSE Approximately 50,000 adults die annually from vaccine-preventable diseases in the United States. Most traditional vaccine providers (eg, physician offices) administer vaccinations during standard clinic hours, but community pharmacies offer expanded hours that allow patients to be vaccinated at convenient times. We analyzed the types of vaccines administered and patient populations vaccinated during off-clinic hours in a national community pharmacy, and their implications for vaccination access and convenience. METHODS We retrospectively reviewed data for all vaccinations given at the Walgreens pharmacy chain between August 2011 and July 2012. The time of vaccination was categorized as occurring during traditional hours (9:00 am–6:00 pm weekdays) or off-clinic hours, consisting of weekday evenings, weekends, and federal holidays. We compared demographic characteristics and types of vaccine. We used a logistic regression model to identify predictors of being vaccinated during off-clinic hours. RESULTS During the study period, pharmacists administered 6,250,402 vaccinations, of which 30.5% were provided during off-clinic hours: 17.4% were provided on weekends, 10.2% on evenings, and 2.9% on holidays. Patients had significantly higher odds of off-clinic vaccination if they were younger than 65 years of age, were male, resided in an urban area, and did not have any chronic conditions. CONCLUSIONS A large proportion of adults being vaccinated receive their vaccines during evening, weekend, and holiday hours at the pharmacy, when traditional vaccine providers are likely unavailable. Younger, working-aged, healthy adults, in particular, a variety of immunizations during off-clinic hours. With the low rates of adult and adolescent vaccination in the United States, community pharmacies are creating new opportunities for vaccination that expand access and convenience. PMID:24019274

    Approximately 50,000 adults die annually from vaccine-preventable diseases in the United States. Most traditional vaccine providers (eg, physician offices) administer vaccinations during standard clinic hours, but community pharmacies offer expanded hours that allow patients to be vaccinated at convenient times. We analyzed the types of vaccines administered and patient populations vaccinated during off-clinic hours in a national community pharmacy, and their implications for vaccination access and convenience. We retrospectively reviewed data for all vaccinations given at the Walgreens pharmacy chain between August 2011 and July 2012. The time of vaccination was categorized as occurring during traditional hours (9:00 am-6:00 pm weekdays) or off-clinic hours, consisting of weekday evenings, weekends, and federal holidays. We compared demographic characteristics and types of vaccine. We used a logistic regression model to identify predictors of being vaccinated during off-clinic hours. During the study period, pharmacists administered 6,250,402 vaccinations, of which 30.5% were provided during off-clinic hours: 17.4% were provided on weekends, 10.2% on evenings, and 2.9% on holidays. Patients had significantly higher odds of off-clinic vaccination if they were younger than 65 years of age, were male, resided in an urban area, and did not have any chronic conditions. A large proportion of adults being vaccinated receive their vaccines during evening, weekend, and holiday hours at the pharmacy, when traditional vaccine providers are likely unavailable. Younger, working-aged, healthy adults, in particular, a variety of immunizations during off-clinic hours.

    To identify an individual as familiar, rodents form a specific type of memory named social recognition memory. The olfactory bulb (OB) is an important structure for social recognition memory, while the hippocampus recruitment is still controversial. The present study was designed to elucidate the OB and the dorsal hippocampus contribution to the consolidation of social memory. For that purpose, we tested the effect of anisomycin (ANI), which one of the effects is the inhibition of protein synthesis, on the consolidation of social recognition memory. Swiss adult mice with cannulae implanted into the CA1 region of the dorsal hippocampus or into the OB were exposed to a juvenile during 5 min (training session; TR), and once again 1.5 h or 24 h later to test social short-term memory (S-STM) or social long-term memory (S-LTM), respectively. To study S-LTM consolidation, mice received intra-OB or intra-CA1 infusion of saline or ANI immediately, 3, 6 or 18 h after TR. ANI impaired S-LTM consolidation in the OB, when administered immediately or 6h after TR. In the dorsal hippocampus, ANI was amnesic only if administered 3 h after TR. Furthermore, the infusion of ANI in either OB or CA1, immediately after training, did not affect S-STM. Moreover, ANI administered into the OB did not alter the animal's performance in the buried food-finding task. Altogether, our results suggest the consolidation of S-LTM requires both OB and hippocampus participation, although in different time points. This study may help shedding light on the specific roles of the OB and dorsal hippocampus in social recognition memory. Copyright © 2014 Elsevier Inc. All rights reserved.

    To develop clinical practice guidelines for nurse-administered procedural sedation and analgesia in the cardiac catheterization laboratory. Numerous studies have reported that nurse-administered procedural sedation and analgesia is safe. However, the broad scope of existing guidelines for the administration and monitoring of patients who receive sedation during medical procedures without an anaesthetist present means there is a lack of specific guidance regarding optimal nursing practices for the unique circumstances where nurse-administered procedural sedation and analgesia is used in the cardiac catheterization laboratory. A sequential mixed methods design was used. Initial recommendations were produced from three studies conducted by the authors: an integrative review; a qualitative study; and a cross-sectional survey. The recommendations were revised according to responses from a modified Delphi study. The first Delphi round was completed by nine senior cardiac catheterization laboratory nurses. All but one of the draft recommendations met the predetermined cut-off point for inclusion with 59 responses to the second round. Consensus was reached on all recommendations. The guidelines that were derived from the Delphi study offer 24 recommendations within six domains of nursing practice: Pre-procedural assessment; Pre-procedural patient and family education; Pre-procedural patient comfort; Intra-procedural patient comfort; Intra-procedural patient assessment and monitoring; and Postprocedural patient assessment and monitoring. These guidelines provide an important foundation towards the delivery of safe, consistent and evidence-based nursing care for the many patients who receive sedation in the cardiac catheterization laboratory setting. © 2013 John Wiley & Sons Ltd.

    The COPD assessment test (CAT) is a questionnaire that assesses the impact of chronic obstructive pulmonary disease (COPD) on health status, but some patients have difficulties filling it up by themselves. We examined whether the mode of administration of the Spanish version of CAT (self vs. interviewer) influences its scores and/or psychometric properties. Observational, prospective study in 49 Spanish centers that includes clinically stable COPD patients (n = 153) and patients hospitalized because of an exacerbation (ECOPD; n = 224). The CAT was self-administered (CAT-SA) or administered by an interviewer (CAT-IA) based on the investigator judgment of the patient's capacity. To assess convergent validity, the Saint George's Respiratory Disease Questionnaire (SGRQ) and the London Chest Activity of Daily Living (LCADL) instrument were also administered. Psychometric properties were compared across modes of administration. A total of 118 patients (31 %) completed the CAT-SA and 259 (69 %) CAT-IA. Multiple regression analysis showed that mode of administration did not affect CAT scores. The CAT showed excellent psychometric properties in both modes of administration. Internal consistency coefficients (Cronbach's alpha) were high (0.86 for CAT-SA and 0.85 for CAT-IA) as was test-retest reliability (intraclass correlation coefficients of 0.83 for CAT-SA and CAT-IA). Correlations with SGRQ and LCADL were moderate to strong both in CAT-SA and CAT-IA, indicating good convergent validity. Similar results were observed when testing longitudinal validity. The mode of administration does not influence CAT scores or its psychometric properties. Hence, both modes of administration can be used in clinical practice depending on the physician judgment of patient's capacity.

  1. Antitumor activity of orally administered maitake α-glucan by stimulating antitumor immune response in murine tumor.

    Yuki Masuda

    Full Text Available Maitake α-glucan, YM-2A, isolated from Grifola frondosa, has been characterized as a highly α-1,6-branched α-1,4 glucan. YM-2A has been shown to possess an anti-virus effect in mice; however, it does not directly inhibit growth of the virus in vitro, indicating that the anti-virus effect of YM-2A might be associated with modulation of the host immune system. In this study, we found that oral administration of YM-2A could inhibit tumor growth and improve survival rate in two distinct mouse models of colon-26 carcinoma and B16 melanoma. Orally administered YM-2A enhanced antitumor immune response by increasing INF-γ-expressing CD4+ and CD8+ cells in the spleen and INF-γ-expressing CD8+ cells in tumor-draining lymph nodes. In vitro study showed that YM-2A directly activated splenic CD11b+ myeloid cells, peritoneal macrophages and bone marrow-derived dendritic cells, but did not affect splenic CD11b- lymphocytes or colon-26 tumor cells. YM-2A is more slowly digested by pancreatic α-amylase than are amylopectin and rabbit liver glycogen, and orally administered YM-2A enhanced the expression of MHC class II and CD86 on dendritic cells and the expression of MHC class II on macrophages in Peyer's patches. Furthermore, in vitro stimulation of YM-2A increased the expression of pro-inflammatory cytokines in Peyer's patch CD11c+ cells. These results suggest that orally administered YM-2A can activate dendritic cells and macrophages in Peyer's patches, inducing systemic antitumor T-cell response. Thus, YM-2A might be a candidate for an oral therapeutic agent in cancer immunotherapy.

  3. Self-Administered Domiciliary tDCS Treatment for Tinnitus: A Double-Blind Sham-Controlled Study.

    Directory of Open Access Journals (Sweden)

    Petteri Hyvärinen

    Full Text Available Transcranial direct current stimulation (tDCS has shown potential for providing tinnitus relief, although positive effects have usually been observed only during a short time period after treatment. In recent studies the focus has turned from one-session experiments towards multi-session treatment studies investigating long-term outcomes with double-blinded and sham-controlled study designs. Traditionally, tDCS has been administered in a clinical setting by a healthcare professional but in studies involving multiple treatment sessions, often a trade-off has to be made between sample size and the amount of labor needed to run the trial. Also, as the number of required visits to the clinic increases, the dropout rate is likely to rise proportionally.The aim of the current study was to find out if tDCS treatment for tinnitus could be patient-administered in a domiciliary setting and whether the results would be comparable to those from in-hospital treatment studies. Forty-three patients with chronic (> 6 months tinnitus were involved in the study, and data on 35 out of these patients were included in final analysis. Patients received 20 minutes of left temporal area anodal (LTA or bifrontal tDCS stimulation (2 mA or sham stimulation (0.3 mA for ten consecutive days. An overall reduction in the main outcome measure, Tinnitus Handicap Inventory (THI, was found (mean change -5.0 points, p < 0.05, but there was no significant difference between active and sham treatment outcomes. Patients found the tDCS treatment easy to administer and they all tolerated it well. In conclusion, self-administered domiciliary tDCS treatment for tinnitus was found safe and feasible and gave outcome results similar to recent randomized controlled long-term treatment trials. The results suggest better overall treatment response-as measured by THI-with domiciliary treatment than with in-hospital treatment, but this advantage is not related to the tDCS variant. The study

    Mephedrone (4-methylmethcathinone (4-MMC)) (MEPH) is a new psychoactive substance (NPS) of the synthetic cathinone class. MEPH has a chiral center and exists as two enantiomers (R-,S-MEPH), yet stereospecific effects of MEPH have not been extensively investigated in preclinical assays. Because significant behavioral and neurochemical differences can exist between enantiomers, probing effects of stereochemistry on biological activity enables separation of adverse and therapeutic effects. Our prior work showed that R-MEPH, relative to S-MEPH, produced greater locomotor activation, place preference, and facilitation of brain reward thresholds in rodents. The present study sought to determine if MEPH enantiomers display stereospecific reward and reinforcement in rat self-administration assays. In Experiment 1, rats were trained to self-administer racemic MEPH (0.50 mg/kg/inf), and dose substitution effects of R-MEPH (0.50 mg/kg/inf) and S-MEPH (0.25, 0.50, 2.00 mg/kg/inf) were examined. In Experiment 2, separate rats were trained to self-administer R-MEPH (0.25, 0.50, 2.00 mg/kg/inf) or S-MEPH (0.25, 0.50, 2.00 mg/kg/inf) and were thereafter evaluated under progressive-ratio access conditions. Within this cohort, 50 kHz ultrasonic vocalizations (USVs) were recorded to measure potential differences in subjective positive affect associated with MEPH enantiomer self-administration. We identified enantiomer- and dose-dependent effects on infusions earned during self-administration following acquisition of racemic MEPH, with greatest infusions under low-effort, fixed-ratio 1 access conditions from low-dose S-MEPH self-administration. When taxed with progressive-ratio access conditions, rats trained to self-administer R-MEPH showed higher break points than those of rats trained to self-administer S-MEPH. Additionally, R-MEPH elicited greatest rates of 50 kHz USVs compared to S-MEPH. Taken together, these data suggest that the R-enantiomer of MEPH is primarily responsible for

    With the aim of assessing the kinetics of a diphosphonate administered by intramuscular injection, we have studied the behaviour of sup(99m)Tc-labelled 1-hydroxy-1, 1-diphosphonate in man and in experimental animals, after intramuscular injection. The curves of plasma and urine radioactivity were analyzed in a six-compartment kinetic model containing seven transition coefficients. The results show that the diphosphonate given by intramuscular injection is absorbed rapidly and completely. Therefore the possibility of using this way of administration should be considered in the pathological conditions in which diphosphonates are used as therapeutic agents. (orig.) [de

    Beta-endorphin is an endogenous opioid peptide that has been hypothesized to be involved in the behavioral effects of drugs of abuse including psychostimulants. Using microdialysis, we studied the effect of cocaine on extracellular levels of beta-endorphin in the nucleus accumbens, a brain region involved in the reinforcing effects of psychostimulant drugs. Experimenter-delivered cocaine (2 mg/kg, i.v.) increased extracellular beta-endorphin immunoreactive levels in the nucleus accumbens, an effect attenuated by 6-hydroxy-dopamine lesions or systemic administration of the D1-like receptor antagonist, SCH-23390 (0.25 mg/kg, i.p.). The effect of cocaine on beta-endorphin release in the nucleus accumbens was mimicked by a local perfusion of dopamine (5 microm) and was blocked by coadministration of SCH-23390 (10 microm). Self-administered cocaine (1 mg/kg/infusion, i.v.) also increased extracellular beta-endorphin levels in the nucleus accumbens. In addition, using functional magnetic resonance imaging, we found that cocaine (1 mg/kg, i.v.) increases regional brain activity in the nucleus accumbens and arcuate nucleus. We demonstrate an increase in beta-endorphin release in the nucleus accumbens following experimenter-delivered and self-administered cocaine mediated by the local dopaminergic system. These findings suggest that activation of the beta-endorphin neurons within the arcuate nucleus-nucleus accumbens pathway may be important in the neurobiological mechanisms underlying the behavioral effects of cocaine.

    Background The apparent interactions between the mechanisms of action of non-steroidal anti-inflammatory drugs (NSAIDS) and steroids suggest that co-therapy may provide beneficial inflammatory and pain relief in the absence of side effects. The aim of the study was to compare the effect of co-administered dexamethasone and diclofenac potassium (diclofenac K) with diclofenac K alone on the postoperative pain, swelling and trismus after surgical removal of third molars. Patients and Methods A prospective randomized double-blind study was conducted at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital, Nigeria. A total of 100 patients were randomly allocated to two treatment groups of dexamethasone (prophylactic 8 mg and postoperative 4 mg IV) and diclofenac K (50 mg Oral before and after surgery), and diclofenac K alone (as with first group). The overall analgesic efficacy of the drug combinations was assessed postoperatively by determination of pain intensity using a category rating scale. Facial swelling was measured using a tape measure placed from tragus to gonion to tragus, while interincisal mouth-opening of patients was measured using a vernier calibrated caliper pre-operatively and post-operatively. Results Co-administration of dexamethasone and diclofenac K was significantly superior to diclofenac alone for the relief of pain (P 0.05). Conclusion This study illustrates enhanced effects of co-administered dexamethasone and diclofenac K on short-term post-operative pain and swelling, compared to diclofenac potassium alone in third molar surgery.

    Outpatient parenteral antibiotic therapy (OPAT) was first reported in 1972. OPAT programmes are not well established in Ireland, with no reported outcomes in the literature. An OPAT programme was established at St. James Hospital in 2006. Demographics, diagnoses and outcomes of the first 60 courses are reported. A retrospective analysis of prospectively recorded data was performed on patients treated from March 2006 to February 2009. The data was analysed using SPSS v.17. Sixty OPAT courses were administered to 56 patients, 57 percent of which were male. The median age was 50 years, the median inpatient stay was 19 days, the median duration of OPAT was 16 days and 1,289 inpatient bed days were saved. The additional cost per day of OPAT was 167.60 euros. Vancomycin was the most prescribed antimicrobial, administered to 35%. Musculoskeletal infection was the indication for treatment in 50%. Confirmatory microbiological diagnosis was identified in 72%, most frequently due to Staphylococcus aureus (68%). Only minor adverse events were recorded. Clinical cure was achieved in 92.8%. A patient satisfaction survey showed high satisfaction. OPAT is a safe and effective way of providing parenteral antibiotic therapy in the Irish healthcare system. Better integration of funding and the appointment of Infectious Diseases specialists will facilitate its expansion.

    The aim of this study was to investigate and compare the in vivo effects of prostaglandin E2 (PGE2) administered by different methods on orthodontic tooth movement and bone metabolism macroscopically, histopatologically, and biochemically. Forty-five young adult New Zealand rabbits were randomly divided into 3 experimental groups (n = 10/group), 1 positive control group (n = 10), and 1 negative control group (n = 5). The experimental rabbits were fitted with springs exerting 20-g reciprocal force on the maxillary incisors and PGE2 (10 µg/mL) was administered by the intravenous, submucosal, or intraligamentous route after appliance insertion and on days 1, 3, 7, and 14 thereafter. All rabbits were sacrificed on day 21 and their premaxillae were resected for histologic evaluation. Tooth movement was observed in the experimental and positive control groups, but the intraligamentous PGE2 group had the highest values of all analyzed parameters, including serum calcium and phosphorus levels and osteoclastic and osteoblastic populations (p orthodontic tooth movement and bone metabolism, but the intraligamentous route seems to be more effective.

    Full Text Available The effects of handling, loading and 12 h of road transportation during the hot-dry season on muscular metabolism of 20 experimental goats administered orally with 100 mg/kg body weight of ascorbic acid (AA dissolved in 10 ml of sterile water, and other 20 control goats given equivalent of sterile water 40 min prior to transportation were investigated. The result obtained post-transportation showed that handling, loading and transportation were stressful to the goats, especially the control goats and resulted into muscular damage and the development of delayed-onset-muscular-soreness (DOMS, which may lead to dark-firm-dry (DFD syndrome meat with undesirable effects on its quality. In the experimental goats administered AA such transportation effects were minimal or completely abolished. The result demonstrated that AA reduced the incidence of DOMS and muscular damage in transported goats, therefore it may be used to improve the welfare and quality of meat obtained from goats subjected to long period of road transportation under adverse climatic conditions.

    Phage endolysins have received increasing attention as potent antibacterial agents. However, although safety evaluation is a prerequisite for the drug development process, a good laboratory practice (GLP)-compliant safety evaluation has not been reported for phage endolysins. A safety evaluation of intravenously administered SAL200 (containing phage endolysin SAL-1) was conducted according to GLP standards. No animals died in any of the safety evaluation studies. In general toxicity studies, intravenously administered SAL200 showed no sign of toxicity in rodent single- and repeated-dose toxicity studies. In the dog repeated-dose toxicity test, there were no abnormal findings, with the exception of transient abnormal clinical signs that were observed in some dogs when daily injection of SAL200 was continued for more than 1 week. In safety pharmacology studies, there were also no signs of toxicity in the central nervous and respiratory system function tests. In the cardiovascular function test, there were no abnormal findings in all tested dogs after the first and second administrations, but transient abnormalities were observed after the third and fourth administrations (2 or 3 weeks after the initial administration). All abnormal findings observed in these safety evaluation studies were slight to mild, were apparent only transiently after injection, and resolved quickly. The safety evaluation results for SAL200 support the implementation of an exploratory phase I clinical trial and underscore the potential of SAL200 as a new drug. We have designed an appropriate phase I clinical trial based on the results of this study.

    To determine whether the use of a human chorionic gonadotropin (hCG) injection as a follicle-maturation trigger affects a patient's reproductive ability during their subsequent menstrual cycle. Patients that were infertile undergoing natural-cycle in vitro fertilization at Kato Ladies Clinic, Japan, between March and June 2012 were enrolled in a prospective cohort study. Patients who had received fertility treatments other than hCG injections were excluded from the study. The remaining patients were divided into two cohorts; patients who had received injection-administered hCG (study group) and patients who had not received any fertility treatment (control group) during their preceding menstrual cycle. The rates of oocyte retrieval, fertilization, clinical pregnancy, and live deliveries were analyzed using a Fisher exact test. The rate of successful oocyte-retrieval (P<0.001) and the delivery-rate (P=0.002) were significantly lower in the study group in comparison with the control group. Additionally, the incidence of empty follicles (P<0.001) and degenerated oocytes (P=0.002) was significantly higher in the exposure group. Triggering follicle maturation with hCG during in vitro fertilization could impact patient fertility during their next cycle. Treatment with hCG injection has the potential to influence not only the cycle during which it is administered, but also the subsequent menstrual cycle.

    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.

Administration of oxytocin to parturient sows reduces duration of labor whereas mortality of the offspring may remain unchanged. This study aimed to evaluate whether time of administration of oxytocin during parturition may alter the uterine response and fetal outcomes. Two hundred parturient sows were randomly assigned to intramuscularly receive either saline solution (control group or oxytocin 0.083 IU/kg immediately after the delivery of the 1st, 4th or 8th piglet (groups O-1, 0-4 and 0-8, respectively. Uterine effects and fetal outcomes were registered in all groups. The duration of labor was 20-40 min shorter (P < 0.0001 and time interval between babies was reduced by 3-5 min (P < 0.0001 in the three groups receiving oxytocin. The duration and intensity of contractions, meconium-stained piglets and intrapartum deaths decreased as time at which oxytocin administered during labor was increased. In group 0-8, we observed approximately 70% less meconium-stained piglets and intrapartum deaths than in the control group. In conclusion, oxytocin administered at early phases of parturition to sows may increase duration and intensity of uterine contractions as well as adverse fetal outcomes

    We aimed to characterize the lipidomic, metabolomic, and transcriptomic profiles in preterm piglets administered enteral (ENT) formula or three parenteral lipid emulsions [parenteral nutrition (PN)], Intralipid (IL), Omegaven (OV), or SMOFlipid (SL), for 14 days. Piglets in all parenteral lipid groups showed differential organ growth versus ENT piglets; whole body growth rate was lowest in IL piglets, yet there were no differences in either energy expenditure or 13C-palmitate oxidation. Plasma homeostatic model assessment of insulin resistance demonstrated insulin resistance in IL, but not OV or SL, compared with ENT. The fatty acid and acyl-CoA content of the liver, muscle, brain, and plasma fatty acids reflected the composition of the dietary lipids administered. Free carnitine and acylcarnitine (ACT) levels were markedly reduced in the PN groups compared with ENT piglets. Genes associated with oxidative stress and inflammation were increased, whereas those associated with alternative pathways of fatty acid oxidation were decreased in all PN groups. Our results show that new generation lipid emulsions directly enrich tissue fatty acids, especially in the brain, and lead to improved growth and insulin sensitivity compared with a soybean lipid emulsion. In all total PN groups, carnitine levels are limiting to the formation of ACTs and gene expression reflects the stress of excess lipid on liver function. PMID:27474222

    Propranolol administered immediately after learning or after recall has been found to impair memory consolidation or reconsolidation (respectively) in animals, but less reliably so in humans. Since reconsolidation impairment has been proposed as a treatment for mental disorders that have at their core an emotional memory, it is desirable to understand how to reliably reduce the strength of pathogenic memories in humans. We postulated that since humans (unlike experimental animals) typically receive propranolol orally, this introduces a delay before this drug can exert its memory impairment effects, which may render it less effective. As a means to test this, in two double-blind placebo-controlled experiments, we examined the capacity of propranolol to impair consolidation and reconsolidation as a function of timing of ingestion in healthy subjects. In Experiment 1, (n=36), propranolol administered immediately after learning or recall failed to impair the consolidation or reconsolidation of the memory of a standardized slideshow with an accompanying emotional story. In Experiment 2 (n=50), propranolol given 60-75min before learning or recall successfully impaired memory consolidation and reconsolidation. These results suggest that it is possible to achieve reliable memory impairment in humans if propranolol is given before learning or before recall, but not after. Copyright © 2016 Elsevier Inc.

    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

    Full Text Available Abstract Background There is no validated gold-standard diagnostic support tool for LSS, and therefore an accurate diagnosis depends on clinical assessment. Assessment of the diagnostic value of the history of the patient requires an evaluation of the differences and overlap of symptoms of the radicular and cauda equina types; however, no tool is available for evaluation of the LSS category. We attempted to develop a self-administered, self-reported history questionnaire as a diagnostic support tool for LSS using a clinical epidemiological approach. The aim of the present study was to use this tool to assess the diagnostic value of the history of the patient for categorization of LSS. Methods The initial derivation study included 137 patients with LSS and 97 with lumbar disc herniation who successfully recovered following surgical treatment. The LSS patients were categorized into radicular and cauda equina types based on history, physical examinations, and MRI. Predictive factors for overlapping symptoms between the two types and for cauda equina symptoms in LSS were derived by univariate analysis. A self-administered, self-reported history questionnaire (SSHQ was developed based on these findings. A prospective derivation study was then performed in a series of 115 patients with LSS who completed the SSHQ before surgery. All these patients recovered following surgical treatment. The sensitivity of the SSHQ was calculated and clinical prediction rules for LSS were developed. A validation study was subsequently performed on 250 outpatients who complained of lower back pain with or without leg symptoms. The sensitivity and specificity of the SSHQ were calculated, and the test-retest reliability over two weeks was investigated in 217 patients whose symptoms remained unchanged. Results The key predictive factors for overlapping symptoms between the two categories of LSS were age > 50, lower-extremity pain or numbness, increased pain when walking

    The purpose of this study was to investigate a means of providing pain relief during repair of facial lacerations in children in the emergency room. This study was conducted in the emergency room of a tertiary care, university-affiliated hospital. Fifty percent nitrous oxide was administered by the surgeon who sutured the laceration. A nurse monitored the child throughout the procedure. At the end of the procedure, pain scores were evaluated by the surgeon and nurse using the FLACC (face, legs, activity, cry, and consolability) scale, a structured observational-behavioral scale for measurement of pain. Sixty patients between the ages of 1 and 16 years participated in the study. Of these, 15 were sutured using standard care (lidocaine infiltration), and 45 children received nitrous oxide in addition to lidocaine infiltration. Nitrous oxide was administered for an average of 11.9 +/- 5.1 minutes (range, 4 to 30 minutes). Forty-three children recovered to preprocedure activity in less than 1 minute. Two children recovered in less than 3 minutes. Average FLACC scores during infiltration and suturing were significantly lower in the nitrous oxide group compared with controls (infiltration, 1.9 of 10 versus 9.7 of 10; suturing, 2 of 10 versus 8.8 of 10). Forceful restraining was necessary in all the controls, whereas in the nitrous oxide group mild force was required in only 15 percent. Seventy percent of the children receiving nitrous oxide had no side effects. Vomiting and nausea were the most common (17 percent), transient side effects. No respiratory or cardiovascular side effects occurred. Nitrous oxide can be safely administered by plastic surgeons while suturing facial lacerations in the emergency room. The fast onset and rapid recovery characteristics of nitrous oxide provide a convenient environment for performing short surgical procedures. This safe method for provision of analgesia and anxiolysis may be appealing to plastic surgeons for ambulatory procedures (e

    Pathways traversed by peripherally administered protein tracers for entry to the mammalian brain were investigated by light and electron microscopy. Native horseradish peroxidase (HRP) and wheat germ agglutinin (WGA) conjugated to peroxidase were administered intranasally, intravenously, or intraventricularly to mice; native HRP was delivered intranasally or intravenously to rats and squirrel monkeys. Unlike WGA-HRP, native HRP administered intranasally passed freely through intercellular junctions of the olfactory epithelia to reach the olfactory bulbs of the CNS extracellularly within 45-90 minutes in all species. The olfactory epithelium labeled with intravenously delivered HRP, which readily escaped vasculature supplying this epithelium. Blood-borne peroxidase also exited fenestrated vessels of the dura mater and circumventricular organs. This HRP in the mouse, but not in the other species, passed from the dura mater through patent intercellular junctions within the arachnoid mater; in time, peroxidase reaction product in the mouse brain was associated with the pial surface, the Virchow-Robin spaces of vessels penetrating the pial surface, perivascular clefts, and with phagocytic pericytes located on the abluminal surface of superficial and deep cerebral microvasculature. Blood-borne HRP was endocytosed avidly at the luminal face of the cerebral endothelium in all species. WGA-HRP and native HRP delivered intraventricularly to the mouse were not endocytosed appreciably at the abluminal surface of the endothelium; hence, the endocytosis of protein and internalization of cell surface membrane within the cerebral endothelium are vectorial. The low to non-existent endocytic activity and internalization of membrane from the abluminal endothelial surface suggests that vesicular transport through the cerebral endothelium from blood to brain and from brain to blood does not occur. The extracellular pathways through which probe molecules enter the mammalian brain offer

This study aimed to assess the analgesic efficacy, adverse effects (AEs, and safety of continuous intravenous (iv oxycodone infusion with ketoprofen (injected into the iv line in patients after THA, and to assay serum oxycodone levels.Patients and methods: Fourteen patients, aged 59‒82 years with American Society of Anesthesiologists (ASA classification I or III, underwent THA with intrathecal analgesia and sedation induced by iv propofol. After the surgery, oxycodone (continuous iv infusion at a dose of 1 mg/h (five patients or 2 mg/h (nine patients with 100 mg ketoprofen (injected into the iv line was administered to each patient every 12 h. Pain was assessed using a numerical rating scale (NRS: 0 – no pain, 10 – the most severe pain at rest and during movement. AEs, including hemodynamic unsteadiness, nausea, vomiting, pruritus, cognitive impairment, and respiratory depression, were registered during the first 24 h after surgery.Results: Oxycodone (continuous iv infusion at a dose of 2 mg/h with ketoprofen (100 mg administered every 12 h provided satisfactory analgesia in all nine patients without the need of rescue analgesics within the first 24 h after THA. In three out of five patients, oxycodone at 1 mg/h was effective. Oxycodone did not induce drowsiness, vomiting, pruritus, respiratory depression, or changes in blood pressure. Bradycardia appeared in two patients, and nausea was observed in one patient.Conclusion: Oxycodone infusion with ketoprofen administered by iv is effective in patients after THA

    To study the feasibility of a multidimensional self-administered questionnaire before the patient is seen at the first visit in a clinical Pain Treatment Unit (PTU) of a tertiary hospital, and its impact on the management of patients in the first visit. Cross-sectional study. Self-administered questionnaire that gathered: socio-demographic data, medical history of pain, pain perception (intensity and characteristics), comorbidity of pain and patient expectations of analgesic treatment ("What do you expect from our treatment? If we cannot resolve your pain, what level of pain would you be willing to live with?). A descriptive analysis was performed. A total of 293 consecutive patients (31% men, 69% women), mean age (SD) 62 (16) years-old, were included in 2011. All patients completed and returned the questionnaire before the first visit to the PTU. The questionnaire was completed fully and correctly by 80% (234, 95% CI: 75-84) of the patients, and the rest completed the questionnaire with some points unanswered. About 24% (70/293, 95% CI: 19-29) of the patients should not have been referred to the PTU [20% were not attended]. A small percentage (9%,26/293, 95% CI: 6-13) were evaluated as «urgent'» and visited over the following 7 days, with 19% (56/293, 95%CI: 15-24) being «preferential» (visited before 15 days) and 52% (152/293, 95% CI: 46-58) as «non-urgent/non-preferential» (visited before 60 days). Almost one third (30%, 87/293, 95% CI: 25-35) did not need a second visit to the PTU. Patient expectations: 21% expected complete pain relief and 64% would accept a lower pain intensity score of 4. The use of a multidimensional self-administered questionnaire before the first visit to a clinical Pain Treatment Unit of a tertiary hospital was a practicable and useful tool for the management of patients on the first visit. Likewise, the questionnaire provided information on the patient's perception of pain and the expectations concerning the analgesic treatment

    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)

    On September 23, 2016, California became the sixth state to pass legislation requiring health plans and insurers to cover a 12-month supply of FDA-approved self-administered hormonal contraceptives such as contraceptive pills, patches and vaginal rings. This legislation is estimated to result in 38% of current contraceptive pill, patch, and ring users receiving a 12-month supply dispensed at one time. This shift in dispensing patterns was estimated to result in a reduction of 15,000 unintended pregnancies; 2000 fewer miscarriages; and 7000 fewer abortions in California decreasing total net health care expenditures by 0.03%. With similar legislation introduced in 17 states, the findings from this study are important for consideration outside of California. Copyright © 2017 Elsevier Inc. All rights reserved.

    Glanzmann's thrombasthenia is an autosomal recessive inherited platelet function defect. Though, quantitatively normal, the aggregation ability of platelets is reduced leading to bleeding episodes requiring transfusion of platelet concentrates. We describe a case of 13-year-old girl who had recurrent episodes of epistaxis since birth and was managed with multiple platelet concentrate transfusions and recently admitted with severe epistaxis refractory to platelet transfusion. At this stage administration of recombinant activated factor VII (fVIIa) was considered, which was initially given at 90 mu g/kg dose with little control of bleeding but subsequent second dose of 120 mu g/kg was administered with excellent response and immediate control of bleeding.

    Full Text Available Dexmedetomidine a highly selective α2 agonist has become a frequently used drug in anesthesiologists’s armamentarium due to its sedative, anxiolytic, analgesic, neuroprotective and anesthetic sparing effects and a favorable side effect profile. Dexmedetomidine–lignocaine combination has been used recently to provide Bier’s block and was shown to improve quality of anesthesia, to reduce tourniquet pain and to reduce postoperative anesthetic requirement in patients undergoing forearm or hand surgeries. Hypotension and bradycardia are the commonly seen side effects. Only one case of dexmedetomidine skin allergy has been reported till date in literature. We present a case of dermatological allergy to dexmedetomidine, in a patient administered Bier’s block with dexmedetomidine–lignocaine combination for implant removal surgery of forearm.

    The efficacy of a live attenuated anti-coccidial vaccine, Paracox-5, administered to 1-day-old chicks was investigated by assessing protection against changes in weight gain following virulent challenge. Vaccinated birds were challenged independently 28 days later with each of the component species (Eimeria acervulina, Eimeria maxima, Eimeria mitis or Eimeria tenella), and protection was demonstrated against associated reduction in weight gain and lesion formation. In addition, an improvement in bird performance, in terms of feed conversion ratio, was also observed following vaccination. Furthermore, under conditions designed to more closely mimic those in the field and using hatchery spray administration, protection against a mixed virulent challenge introduced by 'seeder birds' was demonstrated evenly across a flock of broiler birds within 21 days after vaccination. These data demonstrate that Paracox-5 vaccine will protect broiler chickens against the adverse effects on performance induced by Eimeria spp.

The patients answered two identical questionnaires on separate occasions before treatment. Test......-retest reliability of the questionnaire, correlation between the symptoms and their troublesomeness, and the reproducibility of this correlation were assessed. The percentage of mistakes in answers to each of the questions varied from 1.8% to 49.1%, mainly owing to missing answers in the item groups: appliances......, sexual function and social activities. Test-retest showed a repeat frequency of 50.0%-91.0% for symptoms and 44.6%-82.1% for trouble. A highly significant positive correlation was found between symptoms and trouble, which was most pronounced for questions concerning pain and incontinence...

    Full Text Available The United States Food and Drug Administration (FDA approved two β-adrenergic agonists (βAA for in-feed administration to cattle fed in confinement for human consumption. Anecdotal reports have generated concern that administration of βAA might be associated with an increased incidence of cattle deaths. Our objectives, therefore, were to a quantify the association between βAA administration and mortality in feedlot cattle, and b explore those variables that may confound or modify this association. Three datasets were acquired for analysis: one included information from randomized and controlled clinical trials of the βAA ractopamine hydrochloride, while the other two were observational data on zilpaterol hydrochloride administration to large numbers of cattle housed, fed, and cared for using routine commercial production practices in the U.S. Various population and time at-risk models were developed to explore potential βAA relationships with mortality, as well as the extent of confounding and effect modification. Measures of effect were relatively consistent across datasets and models in that the cumulative risk and incidence rate of death was 75 to 90% greater in animals administered the βAA compared to contemporaneous controls. During the exposure period, 40 to 50% of deaths among groups administered the βAA were attributed to administration of the drug. None of the available covariates meaningfully confounded the relationship between βAA and increased mortality. Only month of slaughter, presumably a proxy for climate, consistently modified the effect in that the biological association was generally greatest during the warmer months of the year. While death is a rare event in feedlot cattle, the data reported herein provide compelling evidence that mortality is nevertheless increased in response to administration of FDA-approved βAA and represents a heretofore unquantified adverse drug event.

    The complex mechanisms of acute inflammation have been subject to veterinary investigations since a long time. However, knowledge on the role of specific inflammatory mediators, as well as pharmacokinetics (PK) and -dynamics (PD) of non-steroidal anti-inflammatory drugs (NSAID) in birds is limited. The objective of this work therefore was to establish a modified tissue cage-model to investigate the acute, carrageenan-mediated inflammatory response, as well as plasma and exudate-kinetics and the antiphlogistic effect of orally administered sodium salicylate on the elicited inflammatory reaction in turkeys. Within the class Aves, comparable studies have so far only been published in chicken. Following bilateral subcutaneous implantation of carrageenan-treated synthetic sponges in the lateral thoracic region, sodium salicylate was administered orally at a dose of 50 mg/kg body weight (BW; therapy group) twice daily on three consecutive days, while a control group received drinking water as a placebo (n = 24 per group). Combined PK and PD of sodium salicylate were evaluated on the basis of salicylate- and prostaglandin (PG) E2-plasma- and -exudate-concentrations, exudate volumes, as well as leukocyte exudate counts. Sodium salicylate was readily absorbed from the gastrointestinal tract and accumulated in the inflammatory exudate. At 4, 6, and 10 h after first application, sodium salicylate significantly reduced PG E2-concentrations in the inflammatory exudate when compared to the control group, whereas leukocyte exudate counts increased over time in both study groups, unaffected by sodium salicylate The described modified tissue cage-model can be beneficial for further research on the pathophysiology of avian inflammatory processes and the investigation of the combined pharmacodynamics and -kinetics of drugs in birds of adequate size.

    Mandibular fractures are the most common facial fractures. They can be treated by conservative techniques or by surgery. The authors hypothesized that the application of a single local dose of strontium chloride would accelerate the healing of subcondylar mandibular fractures, shorten the recovery time and prevent complications. The aim of the present pilot study was to evaluate the effects of a single local dose of strontium chloride on the healing of subcondylar mandibular fractures in rats. This randomized experimental study was carried out on 24 male Wistar albino rats. The rats were randomly divided into 3 groups: experimental group 1, receiving 3% strontium chloride; experimental group 2, receiving 5% strontium chloride; and the control group. A full thickness surgical osteotomy was created in the subcondylar area. A single dose of strontium solution (0.3 cc/site) was administered locally by injection on the bone surfaces of the fracture line created. Nothing was administered to the control group. The mandibles were dissected on postoperative day 21. The fractured hemimandibles were submitted to histopathological examination. The median bone fracture healing score was 9 (range: 7-9) in experimental group 1; 8 (range: 7-10) in experimental group 2; and 7.50 (range: 7-8) in the control group. When the groups were compared in terms of bone healing scores, there was a statistically significant difference between experimental group 1 and the control group (p fractures. In the authors' opinion, 3% strontium was beneficial for accelerating facial skeleton consolidation and bone regeneration in rat subcondylar mandibular fractures. This treatment procedure may be combined with closed fracture treatment or a conservative approach.

    OBJECTIVE To determine the pharmacokinetics of voriconazole administered PO with or without food to red-tailed hawks (Buteo jamaicensus) and whether any observed variability could be explained by measured covariates to inform dose adjustments. ANIMALS 7 adult red-tailed hawks. PROCEDURES In a crossover study design, hawks were randomly assigned to first receive voriconazole (15 mg/kg, PO) injected into a dead mouse (n = 3; fed birds) or without food (4; unfed birds). Sixteen days later, treatments were reversed. Blood samples were collected at various points to measure plasma voriconazole concentrations by ultraperformance liquid chromatography. Pharmacokinetic data were analyzed by noncompartmental methods and fit to a compartmental model through nonlinear mixed-effects regression, with feeding status and body weight investigated as covariates. RESULTS Voriconazole was well absorbed, with quantifiable plasma concentrations up to 24 hours after administration. Mean plasma half-life was approximately 2 hours in fed and unfed birds. Administration of the voriconazole in food delayed absorption, resulting in a significant delay in time to maximum plasma concentration. The final compartmental model included a categorical covariate to account for this lag in absorption as well as body weight as a covariate of total body clearance (relative to unknown bioavailability). CONCLUSIONS AND CLINICAL RELEVANCE A single dose of voriconazole (15 mg/kg) administered PO to red-tailed hawks resulted in mean plasma voriconazole concentrations greater than the targeted value (1 μg/mL). Additional studies with larger sample sizes and multidose regimens are required before the model developed here can be applied in clinical settings.

    Purpose We hypothesize organic cation transporters (OCT) may have a potential role in determining the pharmacokinetics and toxicity of organic cation drugs applied topically. Hence, in the present in vivo study, we attempted to evaluate the role of OCT in modulating the transport of its substrates after topical application. Methods New Zealand albino rabbits of either sex were used. Transcorneal penetration of OCT substrates tetraethylammonium and metformin after single instillation was evaluated in the absence and presence of OCT blockers (quinidine and atropine). Aqueous humor (AH) samples were collected through paracentesis amounting to 70–100 μl under topical anesthesia at various time intervals. The samples were subjected for estimation of both substrate as well as blocker concentrations using liquid chromatography mass spectrometry. Results Topical pre-treatment (30 min before substrate) of OCT blockers significantly decreased the transcorneal penetration of OCT substrates after single topical administration. The levels of blockers reaching AH in the presence of substrates were also modulated at 60 min after its administration as compared with its control. Conclusion OCT are functionally active in the uptake of their substrates from tear to AH. Therefore, OCT in the corneal epithelium may be positioned from apical to basolateral. When administering their substrates/blockers topically, both may be competing for OCT for their uptake across the cornea, thereby decreasing the corneal penetration. Hence OCT can have a potential pharmacokinetic role in modulating the ocular bioavailability of their substrates administered topically, which are used as ocular therapeutics. PMID:23846373

    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 HIV prevalence among people who inject drugs (PWID in Ottawa is estimated at about 10%. The successful integration of peers into outreach efforts and wider access to HIV point-of-care testing (POCT create opportunities to explore the role of peers in providing HIV testing. The PROUD study, in partnership with Ottawa Public Health (OPH, sought to develop a model for community-based peer-administered HIV POCT.PROUD draws on community-based participatory research methods to better understand the HIV risk environment of people who use drugs in Ottawa. From March-October 2013, 593 people who reported injecting drugs or smoking crack cocaine were enrolled through street-based recruitment. Trained peer or medical student researchers administered a quantitative survey and offered an HIV POCT (bioLytical INSTI test to participants who did not self-report as HIV positive.550 (92.7% of the 593 participants were offered a POCT, of which 458 (83.3% consented to testing. Of those participants, 74 (16.2% had never been tested for HIV. There was no difference in uptake between testing offered by a peer versus a non-peer interviewer (OR = 1.05; 95% CI = 0.67-1.66. Despite testing those at high risk for HIV, only one new reactive test was identified.The findings from PROUD demonstrate high uptake of community-based HIV POCT. Peers were able to successfully provide HIV POCT and reach participants who had not previously been tested for HIV. Community-based and peer testing models provide important insights on ways to scale-up HIV prevention and testing among people who use drugs.

    Full Text Available Abstract Background The apparent interactions between the mechanisms of action of non-steroidal anti-inflammatory drugs (NSAIDS and steroids suggest that co-therapy may provide beneficial inflammatory and pain relief in the absence of side effects. The aim of the study was to compare the effect of co-administered dexamethasone and diclofenac potassium (diclofenac K with diclofenac K alone on the postoperative pain, swelling and trismus after surgical removal of third molars. Patients and Methods A prospective randomized double-blind study was conducted at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital, Nigeria. A total of 100 patients were randomly allocated to two treatment groups of dexamethasone (prophylactic 8 mg and postoperative 4 mg IV and diclofenac K (50 mg Oral before and after surgery, and diclofenac K alone (as with first group. The overall analgesic efficacy of the drug combinations was assessed postoperatively by determination of pain intensity using a category rating scale. Facial swelling was measured using a tape measure placed from tragus to gonion to tragus, while interincisal mouth-opening of patients was measured using a vernier calibrated caliper pre-operatively and post-operatively. Results Co-administration of dexamethasone and diclofenac K was significantly superior to diclofenac alone for the relief of pain (P 0.05. Conclusion This study illustrates enhanced effects of co-administered dexamethasone and diclofenac K on short-term post-operative pain and swelling, compared to diclofenac potassium alone in third molar surgery.

    Full Text Available Objective: Dementia is a major public health problem. More and more patients with dementia are being admitted to acute care hospitals for treatment of comorbidities. Issues associated with care of patients with dementia in acute care hospitals have not been adequately clarified. This study aimed to explore the challenges nurses face in providing care to patients with dementia in acute care hospitals in Japan. Methods: This was a qualitative study using focus group interviews (FGIs. The setting was six acute hospitals with surgical and medical wards in the western region of Japan. Participants were nurses in surgical and internal medicine wards, excluding intensive care units. Nurses with less than 3 years working experience, those without experience in dementia patient care in their currently assigned ward, and head nurses were excluded from participation. FGIs were used to collect data from February to December 2008. Interviews were scheduled for 1–1.5 h. The qualitative synthesis method was used for data analysis. Results: In total, 50 nurses with an average experience of 9.8 years participated. Eight focus groups were formed. Issues in administering care to patients with dementia at acute care hospitals were divided into seven groups. Three of these groups, that is, problematic patient behaviors, recurrent problem, and problems affecting many people equally, interact to result in a burdensome cycle. This cycle is exacerbated by lack of nursing experience and lack of organization in hospitals. In coping with this cycle, the nurses develop protection plans for themselves and for the hospital. Conclusions: The two main issues experienced by nurses while administering care to patients with dementia in acute care hospitals were as follows: (a the various problems and difficulties faced by nurses were interactive and caused a burdensome cycle, and (b nurses do their best to adapt to these conditions despite feeling conflicted.

    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 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.

    To determine if buprenorphine plus dexmedetomidine administered via the oral transmucosal route produces sufficient sedation in cats so that students can insert intravenous catheters. Prospective, randomized, blinded, clinical trial. Eighty-seven shelter-owned female cats aged 4-48 months, weighing 1.1-4.9 kg. Cats were randomly allocated to two treatment groups based on route of drug administration: oral transmucosal (OTM), or intramuscular (IM). Buprenorphine (20 microg kg(-1)) plus dexmedetomidine (20 microg kg(-1)) were administered as pre-medicants via one of these two routes. Prior to and 20 minutes after drug administration, heart and respiratory rates, systolic arterial pressure, and posture were measured and recorded. Twenty minutes after drug administration the same variables plus each cat's response to clipper sound, clipping, and restraint were recorded; higher scores indicated more sedation. There were no significant differences between the two groups prior to pre-medication. Within each treatment group heart rate was significantly lower 20 minutes after treatment, but it did not differ significantly between the two groups. Twenty minutes after treatment, respiratory rate was significantly less in the OTM group, but did not differ significantly between the two groups. Systolic arterial pressure did not differ within or between the two groups at either time. Scores for posture increased significantly within both groups, and cats in the IM group had higher scores after treatment. Twenty minutes after treatment, cats in the IM group had higher scores for clipping and restraint than OTM cats. Ketamine (IM) was necessary to facilitate catheterization in 25% and 16% of cats in the OTM and IM groups, respectively, but this was not significantly different. Administration of dexmedetomidine plus buprenorphine by the OTM route is easy to perform, but produces less sedation than the IM route for IV catheterization in cats.

    We conducted a randomized controlled trial among 305 truck drivers from two North Star Alliance roadside wellness clinics in Kenya to see if offering HIV testing choices would increase HIV testing uptake. Participants were randomized to be offered (1) a provider-administered rapid blood (finger-prick) HIV test (i.e., standard of care [SOC]) or (2) a Choice between SOC or a self-administered oral rapid HIV test with provider supervision in the clinic. Participants in the Choice arm who refused HIV testing in the clinic were offered a test kit for home use with phone-based posttest counseling. We compared HIV test uptake using the Mantel Haenszel odds ratio (OR) adjusting for clinic. Those in the Choice arm had higher odds of HIV test uptake than those in the SOC arm (OR = 1.5), but the difference was not statistically significant (p = 0.189). When adding the option to take an HIV test kit for home use, the Choice arm had significantly greater odds of testing uptake (OR = 2.8, p = 0.002). Of those in the Choice arm who tested, 26.9% selected the SOC test, 64.6% chose supervised self-testing in the clinic, and 8.5% took a test kit for home use. Participants varied in the HIV test they selected when given choices. Importantly, when participants who refused HIV testing in the clinic were offered a test kit for home use, an additional 8.5% tested. Offering truck drivers a variety of HIV testing choices may increase HIV testing uptake in this key population.

    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.

    Administration of medication to care recipients is delegated to home-care assistants working in the municipal social care, alongside responsibility for providing personal assistance for older people. Home-care assistants have practical administration skills, but lack formal medical knowledge. The aim of this study was to explore how home-care assistants perceive administration of medication to older people living at home, as delegated to them in the context of social care. Four focus groups consisting of 19 home-care assistants were conducted. Data were analysed using qualitative content analysis. According to home-care assistants, health and social care depends on delegation arrangements to function effectively, but in the first place it relieves a burden for district nurses. Even when the delegation had expired, administration of medication continued, placing the statutes of regulation in a subordinate position. There was low awareness among home-care assistants about the content of the statutes of delegation. Accepting delegation to administer medications has become an implicit prerequisite for social care work in the municipality. Accepting the delegation to administer medication was inevitable and routine. In practice, the regulating statute is made subordinate and consequently patient safety can be threatened. The organisation of health and social care relies on the delegation arrangement to meet the needs of a growing number of older home-care recipients. This is a crucial task which management within both the healthcare professions and municipal social care needs to address, to bridge the gap between statutes and practice, to create arenas for mutual collaboration in the care recipients' best interest and to ensure patient safety. © 2014 John Wiley & Sons Ltd.

    Full Text Available The development of radiation countermeasures for acute radiation syndrome (ARS has been underway for the past six decades, leading to the identification of multiple classes of radiation countermeasures. However, to date, only two growth factors (Neupogen and Neulasta have been approved by the United States Food and Drug Administration (US FDA for the mitigation of hematopoietic acute radiation syndrome (H-ARS. No radioprotector for ARS has been approved by the FDA yet. Gamma-tocotrienol (GT3 has been demonstrated to have radioprotective efficacy in murine as well as nonhuman primate (NHP models. Currently, GT3 is under advanced development as a radioprotector that can be administered prior to radiation exposure. We are studying this agent for its safety profile and efficacy using the NHP model. In this study, we analyzed global metabolomic and lipidomic changes using ultra-performance liquid chromatography (UPLC quadrupole time-of-flight mass spectrometry (QTOF-MS in serum samples of NHPs administered GT3. Our study, using 12 NHPs, demonstrates that alterations in metabolites manifest only 24 h after GT3 administration. Furthermore, metabolic changes are associated with transient increase in the bioavailability of antioxidants, including lactic acid and cholic acid and anti-inflammatory metabolites 3 deoxyvitamin D3, and docosahexaenoic acid. Taken together, our results show that the administration of GT3 to NHPs causes metabolic shifts that would provide an overall advantage to combat radiation injury. This initial assessment also highlights the utility of metabolomics and lipidomics to determine the underlying physiological mechanisms involved in the radioprotective efficacy of GT3.

    Background and purpose: Concurrent chemoradiotherapy (CRT) confers survival benefit over radiotherapy (RT) alone in the treatment of locoregionally advanced nasopharyngeal carcinoma (NPC). This study explored the prognostic significance of the total dose of cisplatin delivered during CRT. Materials and methods: A retrospective analysis was performed in patients with stage II to IVB NPC (AJCC 6th edition) who participated in 3 prospective studies. All patients received cisplatin at a fixed dose of 40 mg/m 2 /week during a 6–7-weeks course of CRT. Chi-square test was used in the univariate analysis. Relationship between prognostic factors, the total dose of cisplatin administered and time-to-event endpoints were analyzed with the Cox Hazards model. Results: Two hundred and forty-one patients were identified with the following stage distribution: Stage II = 13.7%, III = 45.2%, IV = 41.1%. The median total number of cycles of cisplatin administered per patient was 5 cycles (range 1–8 cycles). At a median follow-up of 56.5 months (range 4.2–200.2 months), 93 patients (38.6%) had relapsed and 85 patients (35.2%) died. For all patients, the total number of cycles of cisplatin delivered was significantly associated with survival in the univariate but not the multivariate analysis. In a sub-group analysis of 142 patients with stage II and III NPC, patients who received more than 5 cycles of cisplatin had significantly better overall survival than those who did not (hazard ratio 0.44; 95% confidence interval, 0.23–0.85; p = 0.02). Conclusion: Number of cycles of cisplatin delivered is an independent prognostic factor in patients with stage II–III NPC undergoing CRT with weekly cisplatin.

    Evaluating and comparing the effectiveness of two smartphone-delivered treatments: one based on behavioural activation (BA) and other on mindfulness. Parallel randomised controlled, open, trial. Participants were allocated using an online randomisation tool, handled by an independent person who was separate from the staff conducting the study. General community, with recruitment nationally through mass media and advertisements. 40 participants diagnosed with major depressive disorder received a BA treatment, and 41 participants received a mindfulness treatment. 9 participants were lost at the post-treatment. An 8-week long behaviour programme administered via a smartphone application. Mindfulness: An 8-week long mindfulness programme, administered via a smartphone application. The Beck Depression Inventory-II (BDI-II) and the nine-item Patient Health Questionnaire Depression Scale (PHQ-9). 81 participants were randomised (mean age 36.0 years (SD=10.8)) and analysed. Results showed no significant interaction effects of group and time on any of the outcome measures either from pretreatment to post-treatment or from pretreatment to the 6-month follow-up. Subgroup analyses showed that the BA treatment was more effective than the mindfulness treatment among participants with higher initial severity of depression from pretreatment to the 6-month follow-up (PHQ-9: F (1, 362.1)=5.2, p<0.05). In contrast, the mindfulness treatment worked better than the BA treatment among participants with lower initial severity from pretreatment to the 6-month follow-up (PHQ-9: F (1, 69.3)=7.7, p<0.01); BDI-II: (F(1, 53.60)=6.25, p<0.05). The two interventions did not differ significantly from one another. For participants with higher severity of depression, the treatment based on BA was superior to the treatment based on mindfulness. For participants with lower initial severity, the treatment based on mindfulness worked significantly better than the treatment based on BA. Clinical Trials

    Full Text Available The aim of the study was to determine the mechanical and geometric properties as well as bone tissue density of long bones in primiparous and multiparous dams of minks supplemented with β-hydroxy β-methylbutyrate (HMB and/or 2-oxoketoglutarate (2-Ox during gestation. Powdered 2-Ox was given at the daily dosage of 0.4 g/kg b.w. separately or simultaneously with HMB, which was administered at the daily dosage of 0.02 g/kg b.w. The study demonstrates for the first time that administration of 2-Ox and/or HMB to dams markedly influences bone tissue density and the mechanical and geometrical properties of mother`s bones in minks. Moreover, it was demonstrated that the supplementation was more effective in the thoracic limb, which was comprehensively used in contrast to the pelvic limb. The mechanical parameters and bone tissue density significantly increased in the humerus in multiparous minks. Only such diet may provide satisfactory production results in the animals. Nutritional deficiencies occurring during pregnancies may trigger body`s own reserves to cover the bone mass increase in developing foetuses and support milk production. This can prevent regeneration of dams’ organisms, which negatively affects their reproductive performance. 2-Ox or HMB may be regarded as a protective metabolite when administered orally to minks, counteracting the negative influences of pregnancy and lactation periods on bones condition. Both simultaneous treatment with 2-Ox and HMB and their separate administration were equally effective.

    Few investigations have been conducted on the disposition and fate of silver nanoparticles (AgNP) in pregnancy. The distribution of a single dose of polyvinylpyrrolidone (PVP)-stabilized AgNP was investigated in pregnant rats. Two sizes of AgNP, 20 and 110 nm, and silver acetate (AgAc) were used to investigate the role of AgNP diameter and particle dissolution in tissue distribution, internal dose and persistence. Dams were administered AgNP or AgAc intravenously (i.v.) (1 mg kg -1 ) or by gavage (p.o.) (10 mg kg -1 ), or vehicle alone, on gestation day 18 and euthanized at 24 or 48 h post-exposure. The silver concentration in tissues was measured using inductively-coupled plasma mass spectrometry. The distribution of silver in dams was influenced by route of administration and AgNP size. The highest concentration of silver (μg Ag g -1 tissue) at 48 h was found in the spleen for i.v. administered AgNP, and in the lungs for AgAc. At 48 h after p.o. administration of AgNP, the highest concentration was measured in the cecum and large intestine, and for AgAc in the placenta. Silver was detected in placenta and fetuses for all groups. Markers of cardiovascular injury, oxidative stress marker, cytokines and chemokines were not significantly elevated in exposed dams compared to vehicle-dosed control. NMR metabolomics analysis of urine indicated that AgNP and AgAc exposure impact the carbohydrate, and amino acid metabolism. This study demonstrates that silver crosses the placenta and is transferred to the fetus regardless of the form of silver. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available Mark J Makowsky,1 Andrew J Cave,2 Scot H Simpson1 1Faculty of Pharmacy and Pharmaceutical Sciences, 2Department of Family Medicine, Faculty of Medicine and Dentistry, University of Alberta, Edmonton, AB, Canada Background and objectives: Pharmacists working in primary care clinics are well positioned to help optimize medication management of community-dwelling patients who are at high risk of experiencing medication-related problems. However, it is often difficult to identify these patients. Our objective was to test the feasibility of a self-administered patient survey, to facilitate identification of patients at high risk of medication-related problems in a family medicine clinic. Methods: We conducted a cross-sectional, paper-based survey at the University of Alberta Hospital Family Medicine Clinic in Edmonton, Alberta, which serves approximately 7,000 patients, with 25,000 consultations per year. Adult patients attending the clinic were invited to complete a ten-item questionnaire, adapted from previously validated surveys, while waiting to be seen by the physician. Outcomes of interest included: time to complete the questionnaire, staff feedback regarding impact on workflow, and the proportion of patients who reported three or more risk factors for medication-related problems. Results: The questionnaire took less than 5 minutes to complete, according to the patient's report on the last page of the questionnaire. The median age (and interquartile range of respondents was 57 (45–69 years; 59% were women; 47% reported being in very good or excellent health; 43 respondents of 100 had three or more risk factors, and met the definition for being at high risk of a medication-related problem. Conclusions: Distribution of a self-administered questionnaire did not disrupt patients, or the clinic workflow, and identified an important proportion of patients at high risk of medication-related problems.

    The objective of this study was to compare the biokinetics of injected H-labeled light (HTO) and heavy (DTO) water in CBA/CaJ mice and to compare the organ distribution and/or body content of H administered by chronic ingestion for 1 mo to C57Bl/6J mice, as either H-labeled water or H-labeled amino acids (glycine, alanine and proline). HTO and DTO were administered to CBA/CaJ mice by single intraperitoneal injection and body retention was determined for up to 384 h post-injection. Tritium-labeled water or H-labeled amino acids were given to C57Bl/6J mice ad libitum for 30 d in drinking water. Body content and organ distribution of H during the period of administration and subsequent to administration was determined by liquid scintillation counting. No differences were found between the biokinetics of HTO and DTO, indicating that data generated using HTO can be used to help assess the consequences of H releases from heavy water reactors. The results for H-water showed that the concentration of radionuclide in the mice reached a peak after about 10 d and dropped rapidly after the cessation of H administration. The maximum concentration reached was only 50% of that in the water consumed, indicating that mice receive a significant fraction of their water from respiration. Contrary to the findings of others, the pattern of H retention following the administration of a cocktail of the labeled amino acids was very little different from that found for the water. This is consistent with the suggestion that most of the ingested amino acids were rapidly metabolized, releasing water and carbon dioxide.

    To evaluate the impact of modulation of the membrane-bound efflux pump P-glycoprotein (P-gp) on plasma concentrations of orally administered prednisolone in dogs. 7 healthy adult Beagles. Each dog received 3 treatments (control [no treatment], rifampicin [100 mg/d, PO, for 21 days, as an inducer of P-gp], and ketoconazole [100 mg/d, PO, for 21 days, as an inhibitor of P-gp]). A single dose of prednisolone (1 mg/kg, PO) was administered on day 8 of each treatment period. There was a 7-day washout period between subsequent treatments. Plasma concentrations of prednisolone were determined by use of a validated liquid chromatography-tandem mass spectrometry method. Duodenum and colon biopsy specimens were obtained endoscopically from anesthetized dogs and assessed for P-gp protein labeling via immunohistochemical analysis and mRNA quantification via real-time PCR assay. Total fecal collection was performed for evaluation of effects of P-gp modulation on digestion of nutrients. Rifampicin treatment upregulated duodenal P-gp in dogs and significantly reduced the area under the plasma concentration-time curve of prednisolone. Ketoconazole typically downregulated expression of duodenal P-gp, with a subsequent increase in the area under the plasma concentration-time curve of prednisolone. There was a noticeable interindividual difference in response. Digestion of nutrients was not affected. Modulation of P-gp expression influenced plasma concentrations of prednisolone after oral administration in dogs. Thus, treatment response to prednisolone may be influenced by coadministration of P-gp-modulating medications or feed ingredients.

    Since the early 1980s pain has been recognised in neonates. Much research has been performed over the years into the analgesic effect of sucrose administered for painful procedures performed on the neonate and infant. Studies have reported the endogenous effect of sucrose when used in conjunction with non-nutritive sucking (pacifiers). Sucrose is routinely administered to neonates and infants in the US either on its own or as an adjunct to other pharmacological interventions post-operatively.

    Administering drugs as fixed-dose combinations (FDCs) versus the same active drugs administered as separate pills is assumed to enhance treatment adherence. We synthesized evidence from randomized controlled trials (RCTs) about the effect of FDCs versus separate pills on adherence. We searched PubMed for RCTs comparing a FDC with the same active drugs administered as separate pills, including a quantitative estimate of treatment adherence, without restriction to medical condition. The odds ratio (OR) of optimal adherence with FDCs versus separate pills was used as common effect size and aggregated into a pooled effect estimate using a random effect model with inverse variance weights. Out of 1258 articles screened, only six studies fulfilled inclusion criteria. Across medical conditions, administering drugs as FDC significantly increased the likelihood of optimal adherence (OR 1.33 (95% CI, 1.03–1.71)). Within subgroups of specific medical conditions, the favourable effect of FDCs on adherence was of borderline statistical significance for HIV infection only (OR 1.46 (95% CI, 1.00–2.13)). We observed a remarkable paucity of RCTs comparing the effect on adherence of administering drugs as FDC versus as separate pills. Administering drugs as FDC improved medication adherence. However, this conclusion is based on a limited number of RCTs only. PMID:25276422

    Chloral hydrate is a sedative that has been used for magnetic resonance imaging (MRI). To evaluate the use, effectiveness and safety of chloral hydrate administered by radiologists for the sedation of children who require MRI procedures. We retrospectively reviewed the clinical charts for all patients ages 0 - 10 years old who underwent sedation with chloral hydrate for MRI from January 2000 to December 2010. Demographic factors, dose information, indication for MRI, therapeutic failures and adverse reactions to the drug were reviewed. One thousand, seven hundred and three children (946 males, 757 females) with a median age of 2.5 years (range: 4 days - 9.91 years) received chloral hydrate. Moderate to deep sedation was achieved in 1,618/1,703 (95%) of the patients, 35/1,703 (2.1%) of the patients failed to achieve moderate to deep sedation, and 47/1,703 (2.8%) of the patients woke up during MRI examination. Adverse reactions were present in 31/1,703 (1.8%) of the patients. Three severe adverse reactions occurred (0.18%). A single dose of chloral hydrate (40-60 mg/kg) was administered to 1,477/1,703 patients (86.7%). An additional dose of chloral hydrate (10-20 mg/kg), given 15 min after the first dose or when the patient woke up during the MRI examination, was required in 226/1,703 patients (13.3%). The likelihood of requiring an additional dose in children older than 2 years was 2.2 times the likelihood compared to children younger than 2 years (OR = 2.2 [95%CI: 1.6-3.0]). The use of a reduced dose (<50 mg/kg) was not associated with a higher therapeutic failure rate (OR = 1.04 [95%CI 0.57-1.89]). Chloral hydrate is an appropriate sedation option for pediatric patients in MRI services when strict patient selection criteria are met. The use of a reduced dose does not affect the effectiveness of sedation. The lack of data regarding the presence of transient oxygen desaturation, the time to induce sedation and the exact duration of sedation are limitations of this

    The aqueous leaf extract of Manihot esculenta Crantz (MELE) is being used orally and topically in traditional African medicine for the treatment of inflammation and pain, and claimed to be safe. The anti-inflammatory effects of MELE (100-400 mg/kg, p.o. or 1-4%, w/w in petroleum jelly, topically) were tested against carrageenan-induced paw oedema in rats as well as against xylene-induced ear oedema in mice. The analgesic effect of MELE (100-400 mg/kg, p.o. or 1-4%, w/w in petroleum jelly, topically) was tested against acetic acid-induced (20 microl, 0.6%, v/v in normal saline, i.p.) and acetylcholine-induced (8.3 mg/kg, i.p.) mouse writhing models. At 100-400 mg/kg, p.o. and 1-4% (w/w), topically, MELE produced significant inhibitions of carrageenan-induced rat paw oedema and xylene-induced ear swelling in mice. Effects produced by MELE were significantly higher than those produced by indomethacin (10 mg/kg, s.c. or 1%, w/w in petroleum jelly) in the anti-inflammatory models. For the analgesic effect, MELE (100-400 mg/kg, orally) and (1-4%, w/w, topically), like aspirin (100 mg/kg, i.p.) exhibited significant (P<0.05) inhibition of acetic acid- and acetylcholine-induced mouse writhing tests, compared to untreated control. Effects produced by MELE were significantly lower than those produced by aspirin (100 mg/kg, i.p.) in the analgesic models, except for the topically administered extract on acetylcholine-induced pain. Acute oral administration up to 10 g/kg did not cause death within 14 days, but mortalities were produced in i.p. administered extract with LD(50) of 2.5+/-0.3 g/kg. Based on these, the extract may contain orally safe, topically and orally effective anti-inflammatory and analgesic principles, which justify its use in traditional African medicine.

    This laboratory study compared the efficacy of Bravecto™ (fluralaner), formulated as a chewable tablet, with the efficacy of Advocate® (imidacloprid/moxidectin), formulated for topical administration, against naturally acquired generalized demodicosis in dogs. Sixteen dogs, all diagnosed with generalized demodectic mange, were randomly allocated to two equal groups. Bravecto™ chewable tablets were administered once orally at a minimum dose of 25 mg fluralaner/kg body weight to one group of dogs, while the second group was treated topically on three occasions at 28-day intervals with Advocate® at a minimum dose of 10 mg imidacloprid/kg body weight and 2.5 mg moxidectin/kg body weight. Mites were counted in skin scrapings and demodectic lesions were evaluated on each dog before treatment and at 28-day intervals thereafter over a 12 week study period. Deep skin scrapings (~4 cm(2)) were made from the same five sites on each dog at each subsequent examination. After single oral administration of Bravecto™ chewable tablets, mite numbers in skin scrapings were reduced by 99.8% on Day 28 and by 100% on Days 56 and 84. Mite numbers in the dogs treated topically on three occasions at 28-day intervals with Advocate® were reduced by 98.0% on Day 28, by 96.5% on Day 56 and by 94.7% on Day 84. Statistically significantly (P ≤ 0.05) fewer mites were found on Days 56 and 84 on the Bravecto™ treated dogs compared to Advocate® treated dogs. A marked decrease was observed in the occurrence of erythematous patches, crusts, casts and scales in the dogs treated with Bravecto™ and in the occurrence of erythematous patches in the dogs treated with Advocate®. With the exception of one dog in each treated group, all dogs exhibited hair regrowth ≥ 90% at the end of the study in comparison with their hair-coat at study start. Single oral administration of Bravecto™ chewable tablets is highly effective against generalized demodicosis, with no mites detectable at

    Some studies have shown that nasally administered immunobiotics had the potential to improve the outcome of influenza virus infection. However, the capacity of immunobiotics to improve protection against respiratory syncytial virus (RSV) infection was not investigated before. The aims of this study were: a) to evaluate whether the nasal administration of Lactobacillus rhamnosus CRL1505 (Lr05) and L. rhamnosus CRL1506 (Lr06) are able to improve respiratory antiviral defenses and beneficially modulate the immune response triggered by TLR3/RIG-I activation; b) to investigate whether viability of Lr05 or Lr06 is indispensable to modulate respiratory immunity and; c) to evaluate the capacity of Lr05 and Lr06 to improve the resistance of infant mice against RSV infection. Nasally administered Lr05 and Lr06 differentially modulated the TLR3/RIG-I-triggered antiviral respiratory immune response. Lr06 administration significantly modulated the production of IFN-α, IFN-β and IL-6 in the response to poly(I:C) challenge, while nasal priming with Lr05 was more effective to improve levels of IFN-γ and IL-10. Both viable Lr05 and Lr06 strains increased the resistance of infant mice to RSV infection while only heat-killed Lr05 showed a protective effect similar to those observed with viable strains. The present work demonstrated that nasal administration of immunobiotics is able to beneficially modulate the immune response triggered by TLR3/RIG-I activation in the respiratory tract and to increase the resistance of mice to the challenge with RSV. Comparative studies using two Lactobacillus rhamnosus strains of the same origin and with similar technological properties showed that each strain has an specific immunoregulatory effect in the respiratory tract and that they differentially modulate the immune response after poly(I:C) or RSV challenges, conferring different degree of protection and using distinct immune mechanisms. We also demonstrated in this work that it is possible

    Full Text Available Experiments were carried out with the aim of investigating the modulatory role of ascorbic acid (AA on responses to 8-h road transportation, covering a distance of 260 km at a speed of 40 - 50 km/h, during the harmattan season. Twentynine adult local pigs aged 9 - 12 months served as subjects. Seventeen pigs administered with AA, prior to the transportation, at the dose of 250 mg/kg orally and individually served as experimental animals, and 12 others administered orally with sterile water were used as control animals. The behavioural activities of pigs which included resting (that is, either lying down or standing idle, defaecating, urinating, sniffing, threats of attack (fight, attempts to escape, mounting on one another, hurdling together and routing the floor were monitored with the aid of a video camera without the pigs knowing that they were being observed. Recordings were done based on the number of pigs found performing each activity within 30 min of direct observation, alternated by 30 min of rest and this continued for a period of 4 h. The tape was later watched, analysed and the number of pigs exhibiting each behavioural activity was recorded. Post-transportation, the behavioural activities of standing (94.1 ± 5.8 %, aggressiveness indicated by the percentage of pigs involved in fighting (23.5 ± 6.00 % and attempts to escape (66.67 ± 14.21 % were higher in experimental pigs (P< 0.05 post-transportation than control pigs with the corresponding values of 25.00 ± 3.00 %; 0.00 % and 35.29 ± 11.95 %, respectively. The results showed that road transportation induced considerable behavioural stress resulting in depression of the central nervous system. AA administration pre-transportation reduced the manifestation of stressful behavioural activities in experimental pigs following road transportation. In conclusion, long-term road transportation of pigs during the harmattan season induces behavioural stress, alleviated by AA

    Aquaflor, a feed premix containing the broad spectrum antibacterial agent florfenicol (50% w/w), is being developed for use to control enteric septicemia (ESC) in channel catfish Ictalurus punctatus caused by the gram-negative enterobacterium Edwardsiella ictaluri. The recommended dose of Aquaflor to control ESC is 10 mg/kg body weight (BW)/day for 10 days. The study objective was to determine the safety of Aquaflor administered in feed to channel catfish at doses of 0 (control), 10, 30, and 50 mg/kg BW/day for 20 consecutive days. Parameters evaluated included daily mortality, behavioral (appetite, distribution, flight/fright response), and water chemistry observations, initial and terminal weight measurements, and gross and microscopic pathology. Medicated feed consumption was 67-86% of target with group mean doses of 8.5 mg/kg BW/day, 24.6 mg/kg BW/day, and 34.9 mg/kg BW/day. There were no mortalities or clinically observable changes noted at any of the dose levels tested. Aquaflor-related changes were limited to the food consumption and histopathology data. Although Aquaflor-related decreased feed consumption was noted in the 30 and 50 mg/kg BW/day groups, there were no differences in fish growth among the treatment groups. Aquaflor-related histopathology findings were limited to a histomorphologically evident dose-dependent decrease in hematopoietic/lymphopoietic tissue in the anterior kidneys, posterior kidneys, and spleens of channel catfish.

    Irritable bowel syndrome is a highly prevalent gastrointestinal condition that is known to be associated with maladaptive psychological coping and is extremely costly to the health-care system. Psychotherapy has been found to improve both physical and psychological symptoms in IBS. However, it is unknown whether 'no therapist' or 'minimal therapist' contact self-help psychotherapy programs are effective treatments for IBS. Thus, this paper aims to determine whether 'no therapist' or 'minimal therapist' contact self-help psychotherapy programs are effective treatments for IBS. A search of PubMed, SCOPUS, Cochrane Library, and Ebscohost research databases was conducted without language or date restriction in July 2012. Nine relevant publications were included in the final review, all of which were randomized controlled trials (RCTs) and included an intervention that was primarily self-administered. It was found that 'no therapist' contact self-help programs are likely to have poor results due to lack of engagement in the program, whilst 'minimal therapist' contact programs appear to produce positive results in terms of symptom relief. Trends towards 'minimal therapist' contact self-help programs having a positive impact on quality of life (QOL) and psychological outcomes were evident. 'Minimal therapist' contact psychotherapy programs have the potential to reduce healthcare seeking behaviour and potentially reduce healthcare costs. However, further studies need to be conducted to confirm this effect as there is poor standardisation in the measurements of the available studies. Copyright © 2013 Elsevier Inc.

    The aim of this study was to evaluate the combination of bupivacaine and methadone administered epidurally in sheep. Six healthy female mixed-breed sheep weighing 35-46 kg and aged 12-18 months were included. Each sheep was assigned to receive three treatments: 0.5 mg/kg 0.25% bupivacaine (BP), 0.3 mg/kg 1% methadone (MT) or 0.25 mg/kg bupivacaine and 0.15 mg/kg methadone (BPMT). All drugs were injected into the lumbosacral space through an epidural catheter. Each animal received each treatment at random. Heart rate, arterial blood pressure (systolic, diastolic and mean), respiratory rate, rectal temperature, analgesia, sedation and motor block were determined before treatment and at predetermined intervals. The duration of analgesia was 240, 220, and 180 min for BP, MT and BPMT, respectively (P blood pressure or respiratory rate. Our findings suggest that lumbosacral epidural administration of bupivacaine, methadone or a combination of the two drugs can provide perioperative analgesia in sheep as part of their management for surgical procedures in the flank and hindlimbs. © 2015 Australian Veterinary Association.

    The affordability to rabies vaccine for intramuscular administration in post exposure prophylaxis is a major constraint. Therefore, in countries, where there are financial constraints, World Health Organization recommends intradermal rabies vaccination that reduces the quantity and cost of vaccination. This study was done to evaluate the safety and immunogenicity of indigenously developed rabies vaccine (VaxiRab N) in comparison to a WHO recommended rabies vaccine (Rabipur) with demonstrated efficacy when administered by intradermal route using updated Thai Red Cross regimen. Eighty-six dog bite cases were randomly given either VaxiRab N (n = 43) or Rabipur (n = 43) as post exposure prophylaxis. The rabies virus neutralizing antibody concentrations on days 14, 28, 90, and 180 were tested by modified rapid fluorescent focus inhibition test. The geometric mean RVNA concentration of both the groups were compared using t- test and was found that, P value > 0.05 on all days, thus showing no significant difference between the 2 groups. The adverse drug events were also compared using Z-test and was found to be not statistically significant (Z = 1.476, P = 0.139). In conclusion, VaxiRab N was found to be safe and effective in post exposure prophylaxis by intradermal route and was similar to the WHO recommended rabies vaccine (Rabipur) of demonstrated efficacy.

    The aim of this study was to compare the systemic exposure of lercanidipine (Zanidip) after oral administration in the fasted state and 15 min before food intake (meals) to investigate if the recommendations in the Summary of Product Characteristics (SPC) with respect to the intake of meals are adequate. The results of three pilot bioequivalence studies performed to develop a lercanidipine generic product, where Zanidip was administered consistently as reference product in the fasted state or 15 min before a standard breakfast, were compared to estimate the drug–food interaction and the similarity of the methods of administration defined in the SPC. The ingestion of a standard (non-high-fat, non-high-calorie) meal 15 min after drug intake increased the area under the concentration–time curve (AUC(0-t)) of S-lercanidipine by 1.78-fold [90% confidence interval (CI) 1.48–2.15, Pfood intake does not seem to be consistent with this recommendation. The Marketing Authorisation Holder should clarify the dosing instructions in relation to meals and identify a sufficient time-lapse to ensure an exposure similar to that obtained in phase III clinical efficacy studies.

    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)

    To explore the psychometric properties of the full 22-item English (UK and US) version of the Zarit Caregiver Burden Interview administered to caregivers to patients with Duchenne muscular dystrophy. Caregivers to patients with Duchenne muscular dystrophy from the United Kingdom and the United States, recruited through the TREAT-NMD network, completed the Zarit Caregiver Burden Interview online. The psychometric properties of the Zarit Caregiver Burden Interview were examined using Rasch analysis. A total of 475 caregivers completed the Zarit Caregiver Burden Interview. Model misfit was identified for 9 of 22 items (mean item fit residual 0.061, SD: 2.736) and 13 of 22 items displayed disordered thresholds. The overall item-trait interaction chi-square value was 499 (198 degrees of freedom, p Duchenne muscular dystrophy from the United Kingdom and the United States.

The Zarit Caregiver Burden Interview is one of the most widely applied measures of caregiver burden. Our Rasch analysis suggests that the Zarit Caregiver Burden Interview is not fit for purpose to measure burden in UK and US caregivers to patients with Duchenne muscular dystrophy. Clinicians and decision-makers should interpret Zarit Caregiver Burden Interview data from these populations with caution.

    Orthorexia, from the Greek words orthos (straight, proper) and orexis (appetite), is a newly conceptualized disorder characterized by distorted eating habits and cognitions concerning supposedly healthy nutrition. In this article we present preliminary results of a wider research aimed to investigate the diffusion of Orthorexia in the general population and to highlight its characteristics and particularly the relationship with Eating Disorder and Obsessive-Compulsive Disorder. One-hundred and seventy seven adult subjects from the general population, were administered the ORTO-15 test, a selfadministered questionnaire specifically designed to assess orthorexic symptomatology; note that statistical analyses were repeated twice, referring to different diagnostic thresholds (40/35). Orthorexia had a 57.6% prevalence in our sample, using the 40-point threshold, with a female/male ratio 2:1; the figure was sensibly lower with the 35-point threshold (21%). The results of this study highlight the diffusion of Orthorexia which may constitute an important risk factor for mental and physical health, but also the opportunity of more specific diagnostic instruments, so to facilitate a thorough understanding of this disorder.

    An automated model development was performed for simvastatin, co-administered with amlodipine concurrently or non-concurrently (i.e., 4 hours later) in 17 patients with coexisting hyperlipidemia and hypertension. The single objective hybrid genetic algorithm (SOHGA) was implemented in the NONMEM software by defining the search space for structural, statistical and covariate models. Candidate models obtained from the SOHGA runs were further assessed for biological plausibility and the precision of parameter estimates, followed by traditional backward elimination process for model refinement. The final population pharmacokinetic model shows that the elimination rate constant for simvastatin acid, the active form by hydrolysis of its lactone prodrug (i.e., simvastatin), is only 44% in the concurrent amlodipine administration group compared with the non-concurrent group. The application of SOHGA for automated model selection, combined with traditional model selection strategies, appears to save time for model development, which also can generate new hypotheses that are biologically more plausible. © 2013, The American College of Clinical Pharmacology.

    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.

    Metabolic syndrome, encompassing type 2 diabetes mellitus and cardiovascular disease, is a growing health concern of industrialized countries. Ferulic acid (FA) is a phenolic acid found in foods normally consumed by humans that has demonstrated antioxidant activity, cholesterol-lowering capabilities, and anti-tumorigenic properties. Select probiotic bacteria, including Lactobacillus fermentum NCIMB 5221, produce FA due to intrinsic ferulic acid esterase activity. The aim of the present research was to investigate a FA-producing probiotic, L. fermentum NCIMB 5221, as a biotherapeutic for metabolic syndrome. The probiotic formulation was administered daily for 8 weeks to Zucker diabetic fatty (ZDF) rats, a model of hyperlipidemia and hyperglycemia. Results show that the probiotic formulation reduced fasting insulin levels and insulin resistance, significantly reduced serum triglycerides (p = 0.016), lowered serum low-density lipoprotein cholesterol levels (p = 0.008), and significantly reduced the atherogenic (p = 0.016) and atherosclerosis (p = 0.012) index as compared to the control animals. In addition, the probiotic formulation significantly increased high-density lipoprotein cholesterol levels (p = 0.041) as compared to the control animals. This research indicates that administration of the FA-producing L. fermentum NCIMB 5221 has the potential to reduce insulin resistance, hyperinsulinemia, hypercholesterolemia, and other markers involved in the pathogenesis of metabolic syndrome. Further studies are required to investigate the human clinical potential of the probiotic formulation in affecting the markers and pathogenesis of metabolic syndrome.

    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 aim was to determine whether orally administered ovine serum immunoglobulins modulate the gut microbiota in the growing rat. Thirty Sprague-Dawley male rats were used in a 21-d study and fed either a basal control diet (control; no immunoglobulin) or a similar diet containing freeze-dried ovine immunoglobulin (ovine Ig) with 15 individually fed rats per diet. Bacterial DNA isolated from ileal and colonic digesta were subjected to PCR-denaturing gradient gel electrophoresis (PCR-DGGE). In the ileum, the DGGE band number and diversity index were greater (P < 0.05) for rats fed the ovine Ig than those fed the control diet. The DNA sequencing of a selected DGGE band in the ovine Ig-fed rats revealed 99% similarity to the Lactobacillus strains. The quantitative PCR data revealed that supplementation of the diet with the ovine Ig fraction supported the growth of Lactobacillus and conversely decreased the number of enterobacteria in ileal and colonic digesta. Inclusion of the ovine Ig fraction led to a greater (P < 0.05) ratio for total Lactobacillus to total bacteria and total Lactobacillus to enterobacteria. The results from the present study show that dietary supplementation with ovine Ig may alter the intestinal environment by a specific enrichment of Lactobacillus strains and depletion of enterobacteria.

    This study sought to examine the prevalence rates of and gender differences among impulse-control disorders in a college sample. During the fall semester of 2006, 791 college students from 2 private colleges in the Midwest completed a self-administered, modified version of the Minnesota Impulse Disorders Interview to assess lifetime rates of DSM-IV-TR-diagnosed impulse-control disorders. Participation was voluntary and anonymous. The mean age of the sample was 20.0 +/- 1.25 years, with females comprising 67.9% of the respondents. Of the individuals, 10.4% (n = 82) met criteria for at least 1 lifetime impulse-control disorder. The most common disorders were trichotillomania (3.91%) and compulsive sexual behavior (3.66%). Kleptomania was the least common (0.38%). Males were significantly more likely to screen positive for pathological gambling (P = .003) and compulsive sexual behavior (P = .002). Females were more likely to have compulsive buying (P = .033). Impulse-control disorders appear to be common among college students. The high rates indicate that these disorders may be incipient during late adolescence and early adulthood and should be addressed prior to onset of clinical versions of the impulse-control disorder.
