The purpose of this study was to determine the effectiveness of antihistamine therapy for withdrawal movements caused by rocuronium injection. One hundred seventy one ASA I-II adults undergoing elective surgery were randomly assigned to one of two groups. Patients in the control group (Group C) were premedicated with 2 mL normal saline, and those in the antihistamine group (Group A) were pre-medicated with 2 mL (45.5 mg) pheniramine maleate. After the administration of thiopental sodium 5 mg/kg, rocuronium 0.6 mg/kg was injected. Withdrawal movements were assessed using a four-grade scale. The administration of antihistamine reveals lower grade of withdrawal movement after rocuronium injection. PMID:19794987

Acute otitis media (AOM) is a common and important source of morbidity in children, although the majority of cases resolve spontaneously. While frequently recommended, decongestant and antihistamine therapy is of unclear benefit. To determine the efficacy of decongestant and antihistamine therapy in children with AOM on outcomes of AOM resolution, symptom resolution, medication side effects, and complications of AOM. In this updated review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 2); MEDLINE (January 2004 to May 2007); and EMBASE (July 2003 to May 2007). Randomized controlled trials (RCTs) evaluating decongestant or antihistamine treatment for children with AOM were included. Patient-oriented outcomes were considered most relevant. The review authors independently evaluated studies for inclusion, performed validity assessments and completed data extraction. Dichotomous data were pooled to generate relative risks; homogeneity was assessed using approximate chi-square tests. No new studies were included following this updated search. Fifteen trials involving 2695 people were included. Only the combined decongestant-antihistamine group demonstrated statistically lower rates of persistent AOM at the two week period (fixed relative risk (RR) 0.76; 95% confidence interval (CI) 0.60 to 0.96; number needed to treat (NNT) 10). No benefit was found for early cure rates, symptom resolution, prevention of surgery or other complications. There was a five to eight -fold increased risk of side effects for those receiving an intervention, which reached statistical significance for all decongestant groupings. Validity sub analyses demonstrated that lower quality studies found benefit, while analysis of those studies with higher validity scores found no benefit of treatment. Given lack of benefit and increased risk of side effects, these data do not support the use of decongestant treatment in children with AOM

Rational selection of a second-generation H1-antihistamine requires efficacy and safety considerations, particularly regarding central nervous system (CNS) effects (cognitive and psychomotor function), potential for driving impairment, minimal sedative effects and a lack of interactions. This review evaluates the key safety features of the non-sedating antihistamine, bilastine, during driving and in preventing road traffic accidents. Among the second-generation H1-antihistamines, sedative effects which can affect cognitive and psychomotor performance, and possibly driving ability, may not be similar. Bilastine is absorbed rapidly, undergoes no hepatic metabolism or cytochrome P450 interaction (minimal drug-drug interaction potential), and is a substrate for P-glycoprotein (limiting CNS entry). Positron emission tomography showed that, compared with other second-generation H1-antihistamines, bilastine has the lowest cerebral histamine H1-receptor occupancy. Bilastine 20 mg once daily (therapeutic dose) is non-sedating, does not enhance the effects of alcohol or CNS sedatives, does not impair driving performance and has at least similar efficacy as other second-generation H1-antihistamines in the treatment of allergic rhinoconjunctivitis and urticaria. Current evidence shows that bilastine has an optimal benefit-to-risk ratio, meeting all conditions for contributing to safety in drivers who need antihistamines, and hence for being considered as an antihistamine of choice for drivers.

The Unani eye drop is an ophthalmic formulation prepared for its beneficial effects in the inflammatory and allergic conditions of the eyes. In the present study, the Unani eye drop formulation was prepared and investigated for its anti-inflammatory and antihistaminic activity, using in vivo and in vitro experimental models respectively. The Unani eye drop formulation exhibited significant anti-inflammatory activity in turpentine liniment-induced ocular inflammation in rabbits. The preparation also showed antihistaminic activity in isolated guinea-pig ileum. The anti-inflammatory and antihistaminic activity of eye drop may be due to presence of active ingredients in the formulation. Although there are many drugs in Unani repository which are mentioned in classical books or used in Unani clinical practice effectively in treatment of eye diseases by various Unani physicians. Inspite of the availability of vast literature, there is a dearth of commercial Unani ocular preparations. So, keeping this in mind, the eye drop formulation was prepared and its anti-inflammatory and antihistaminic activity was carried out in animal models. Thus, in view of the importance of alternative anti-inflammatory and antiallergic drugs, it becomes imperative to bring these indigenous drugs to the front foot and evaluate their activities.

One of the antihistamines that had been claimed to belong to such a group is the second-generation antihistamine, ebastine. The objective of this review is to analyze the pharmacology of ebastine, in light of the CONGA recommendations for the development of new-generation antihistamines: (1 anti-inflammatory properties, (2 potency, efficacy and effectiveness, (3 lack of cardiotoxicity, (4 lack of drug interactions, (5 lack of CNS effects, and (6 pharmacological approach. Ebastine seems to have anti-inflammatory properties that help to ameliorate nasal congestion, though this has not yet been conclusively demonstrated. Its pharmacological–therapeutic profile does not differ greatly from that of other second-generation antihistamines. Its cardiac safety has been widely assessed and no cardiac toxicity has been found at therapeutic doses despite initial concerns. The risk of potentially relevant drug interactions has been investigated and ruled out. Ebastine does not produce sedation at therapeutic doses and drug interaction studies with classical CNS depressants have not demonstrated a synergistic effect. Pharmacologically, ebastine is an H1 inverse agonist. Perhaps the answer to the quest for new-generation antihistamines lies not only in H1 but in a combined approach with other histamine receptors.Keywords: ebastine, antihistamines, third-generation, CONGA

The drugs of choice in the treatment of urticaria in children are H1-antihistamines. The aim of the study was to evaluate children with urticaria and define risk factors for requirement of high-dose H1-antihistamines in children with urticaria. The medical data of children who were diagnosed as having urticaria admitted to our outpatient clinic between January 2014 and January 2016 were searched. The medical histories, concomitant atopic diseases, parental atopy histories, medications, treatment responses, blood eosinophil and basophil counts, and serum total IgE levels were recorded. In addition, the urticaria activity score for seven days, autoimmune antibody tests, and skin prick test results were evaluated in children with chronic urticaria. The numbers of the children with acute and chronic urticaria were 138 and 92, respectively. The age of the children with chronic urticaria was higher than that of those with acute urticaria (p0.05). There was a negative correlation between blood eosinophil count and the UAS7 score in children with chronic urticaria (r=-0.276, p=0.011). Chronic urticaria and requirement of high dose H1-antihistamines were significant in children aged ≥10 years (p<0.001, p=0.015). High UAS7 score (OR: 1.09; CI 95%: [1.03-1.15]) and basopenia (OR: 6.77; CI 95%: [2.01-22.75]) were associated with the requirement of high-dose H1-AH in children with chronic urticaria. The requirement of high-dose H1-antihistamines was higher with children's increasing age. Disease severity and basopenia were risk factors for the requirement of high-dose H1-antihistamines.

Background Allergies have been associated with decreased risk of glioma, but associations between duration and timing of allergies, and antihistamine use and glioma risk have been less consistent. The objective was to investigate this association by analyzing types, number, years since diagnosis, and age at diagnosis of allergies, and information on antihistamine usage, including type, duration, and frequency of exposure. Methods Self-report data on medically-diagnosed allergies and antihistamine use were obtained for 419 glioma cases and 612 hospital-based controls from Duke University and NorthShore University HealthSystem. Results High- and low-grade glioma cases were statistically significantly less likely to report any allergy than controls (OR= 0.66, 95% CI: 0.49–0.87 and 0.44, 95% CI: 0.25–0.76, respectively). The number of types of allergies (seasonal, medication, pet, food, and other) was inversely associated with glioma risk in a dose-response manner (p-value for trend Impact A comprehensive study of allergies and antihistamine use using standardized questions and biological markers will be essential to further delineate the biological mechanism that may be involved in brain tumor development.

In the course of our validation program testing blood-brain barrier (BBB) in vitro models for their usability as tools in drug discovery it was evaluated whether an established Transwell model based on porcine cell line PBMEC/C1-2 was able to differentiate between the transport properties of first and second generation antihistaminic drugs. First generation antihistamines can permeate the BBB and act in the central nervous system (CNS), whereas entry to the CNS of second generation antihistamines is restricted by efflux pumps such as P-glycoprotein (P-gP) located in brain endothelial cells. P-gP functionality of PBMEC/C1-2 cells grown on Transwell filter inserts was proven by transport studies with P-gP substrate rhodamine 123 and P-gP blocker verapamil. Subsequent drug transport studies with the first generation antihistamines promethazine, diphenhydramine and pheniramine and the second generation antihistamines astemizole, ceterizine, fexofenadine and loratadine were accomplished in single substance as well as in group studies. Results were normalised to diazepam, an internal standard for the transcellular transport route. Moreover, effects after addition of P-gP inhibitor verapamil were investigated. First generation antihistamine pheniramine permeated as fastest followed by diphenhydramine, diazepam, promethazine and second generation antihistaminic drugs ceterizine, fexofenadine, astemizole and loratadine reflecting the BBB in vivo permeability ranking well. Verapamil increased the transport rates of all second generation antihistamines, which suggested involvement of P-gP during their permeation across the BBB model. The ranking after addition of verapamil was significantly changed, only fexofenadine and ceterizine penetrated slower than internal standard diazepam in the presence of verapamil. In summary, permeability data showed that the BBB model based on porcine cell line PBMEC/C1-2 was able to reflect the BBB in vivo situation for the transport of

Histamine is a mediator of many physiological processes. It plays an important role in modulating allergy reactions and immune system responses. H1 receptor is a therapeutic target for drugs applied in allergic diseases such as allergic rhinoconjunctivitis, urticarial, or atopic dermatitis. H1-antihistamines display different chemical structures, pharmacokinetics and a potential for drug-drug and drug-food interactions. Drug-food interactions are known to reduce therapeutic effects of the medicine, as well as to induce a potent adverse drug reactions. Considering it all, a systematic review was conducted to investigate the importance of drug-food interaction for H1-antihistamine drugs. As non-sedating second generation H1-antihistamines remain to be drugs of choice in treating allergic conditions, the review has been focused on this particular class of medicines. The aim of this paper is to examine the evidence of food-drug and food-alcohol interactions for second generation H1-antihistamine drugs. A systematic literature queries were performed in the following databases: Medline (via PubMed), Cochrane Library, Embase and Web of Science (all from their inception date till October 2016). The queries covered nine specific names of second generation anthistamine drugs, namely bilastine, cetirizine, desloratadine, ebastine, fexofenadine, levocetirizine, loratadine, mizolastine, and rupatadine, in combinations with such terms as "food", "juice", "grapefruit", "fruits", "alcohol", "pharmacokinetics", and "meal". Additional publications were found by checking all the reference lists. Where none data on drug-food interaction could be found within the investigated databases, a specific drug prescribing information was used. 2326 publications were identified with the database queries. Articles were subjected to analysis by reviewing their title, abstract and full text; duplicated papers were removed. Having collected a complete set of data, a critical review was undertaken

Potential negative effects of anti-histamines on male reproductive function.

Histamine (HA) is a pleiotropic biogenic amine synthesized exclusively by histidine decarboxylase (HDC) in most mammalian tissues. The literature on the role of HA within the male gonad has expanded over the last years, attracting attention to potential unexpected side-effects of anti-histamines on testicular function. In this regard, HA receptors (HRH1, HRH2 and HRH4) have been described in Leydig cells of different species, including human. Via these receptors, HA has been reported to trigger positive or negative interactions with the LH/hCG signaling pathway depending upon its concentration, thereby contributing to the local control of testicular androgen levels. It should then be considered that anti-histamines may affect testicular homeostasis by increasing or decreasing steroid production. Additionally, HRH1 and HRH2 receptors are present in peritubular and germ cells, and HRH2 antagonists have been found to negatively affect peritubular cells and reduce sperm viability. The potential negative impact of anti-histamines on male reproduction becomes even more dramatic if we consider that HA has also been associated with human sexual behavior and penile erection. What is more, although testicular mast cells are the major source of locally produced HA, recent studies have described HDC expression in macrophages, Leydig cells and germ cells, revealing the existence of multiple sources of HA within the testis. Undoubtedly, the more we learn about the testicular histaminergic system, the more opportunities there will be for rational design of drugs aimed at treating HA-related pathologies, with minimum or nule negative impact on fertility. © 2018 Society for Reproduction and Fertility.

The effect of gamma irradiation of pgeniramine maleate and menhydrinate solutions at the radiation levels of 15,25 and 50KGY on their toxicity has been investigated. Irradiation of pheniramine maleate and dimenhydrinate solutions at dose levels of 15,25 and 50KGY resulted in no significant change in neither the gross toxicity of the two drugs nor in their LD 50's on rats. Pheniramine maleate and dimenhydrinate whether irradiated or not, resulted in no significant increase in serum GPT or alkaline phosphatase activities when given at a dose of 15mg/Kg suggesting no significant alteration to liver function in rats. Higher doses of the two antihistaminics, namely, the minimal lethal doses and the LD 50's induced hydropic degeneration of liver cells, lymphocytic infiltration of the portal tract and focal areas of necrosis of hepatic cells mostly in the central lobule. Fatty infiltration was observed with dimenhydrinate. Radiation treatment of those antihistamines up to 50KGY resulting in no alteration in their toxicity projects the high radiation stability of pheniramine maleate and dimenhydrinate and confirms gamma irradiation is a successful method for their sterilization

Full Text Available OBJETIVO: Avaliar criticamente os mais novos anti-histamínicos anti-H1 e os diferentes termos utilizados para denominá-los, com base na revisão de evidências sobre o papel dos anti-H1 no tratamento das doenças alérgicas. FONTES DOS DADOS: Artigos originais, revisões e consensos indexados nos bancos de dados MEDLINE e PUBMED de 1998 a 2006. Palavra chave: anti-histamínicos. SÍNTESE DOS DADOS: Os anti-histamínicos de segunda geração diferenciam-se dos de primeira geração por sua elevada especificidade e afinidade pelos receptores H1 periféricos e pela menor penetração no sistema nervoso central (SNC, com conseqüente redução dos efeitos sedativos. Embora os anti-histamínicos de segunda geração sejam, geralmente, melhor tolerados do que seus predecessores, alguns efeitos adversos, principalmente cardiotoxicidade, surgiram com alguns deles. Nos últimos 20 anos, novos compostos, com diferentes farmacocinéticas, foram sintetizados. A maioria deles manifesta propriedades antiinflamatórias que independem de sua atividade no receptor H1. Aprimoramentos mais recentes, geralmente na forma de metabólitos ativos, levaram ao uso do termo anti-histamínico de terceira geração. Esse termo surgiu espontaneamente, sem uma descrição clara de seu significado e implicações clínicas, criando grande confusão entre os profissionais da saúde. CONCLUSÕES: Com base nas evidências sobre anti-histamínicos anti-H1, nenhum deles pode ser considerado como "anti-histamínico de terceira geração". Para tanto, seria preciso comprovar que a nova classe de anti-histamínicos possui vantagens clínicas distintas sobre os compostos existentes e preenche pelo menos três pré-requisitos: ausência de cardiotoxicidade, de interações medicamentosas e de efeitos sobre o SNC.OBJECTIVE: To perform a critical evaluation of the more recent H1 antihistamines and the various terms used to describe them, based on a review of evidence on their role in

The widely used antihistamine diphenhydramine is present in municipal biosolids, and is detected in runoff from agricultural land fertilized with biosolids. In the present study the kinetics and major pathways of diphenhydramine dissipation in a loam, sandy loam, and clay loam soil were determined in laboratory incubations. The time to dissipate 50% (DT 50 ) of 14 C-diphenhydramine residues at 30 °C ranged from 88 ± 28 days in the clay loam to 335 ± 145 days in the loam soil. Mineralization of 14 C was insignificant, and diphenhydramine-N-oxide was the only detected extractable transformation product elucidated by radioisotope and HPLC-MS methods. There were no significant effects of municipal biosolids on the kinetics or pathways of removal. Overall, diphenhydramine is quite persistent in soils, and formation of non-extractable soil-bound residues is the major mechanism of diphenhydramine dissipation. -- Highlights: ► Diphenhydramine is a widely used antihistamine drug, is found in biosolids, and in runoff from biosolids-fertilized fields. ► The persistence of 14 C-diphenhydramine was evaluated in soils. ► Half lives ranged from 88 to 335 days.

Conclusions: The sedative properties of the H1 antihistamines obtained from VAS analysis were very similar to those of H1R occupancy from positron emission tomography (PET studies and PIR from meta-analysis. Our results indicate that large-scale surveillance using VAS might be useful to evaluate the profiles of H1 antihistamines.

Safety and efficacy of bilastine: a new H(1)-antihistamine for the treatment of allergic rhinoconjunctivitis and urticaria.

Church, Martin K

2011-09-01

New H(1)-antihistamines should be effective in relieving the symptoms of allergic disease, should have a rapid onset and long duration of action and should neither cause sedation nor interact with cytochrome P450. A review of bilastine was undertaken to determine whether this newer H(1)-antihistamine meets these requirements. A Medline search was conducted to identify preclinical and clinical studies of bilastine. This was supplemented with additional articles or abstracts cited in reference lists and/or obtained from online sources and internal reports supplied by Faes Farma. Review of these data indicated that bilastine has high selectivity for H(1)-receptors, is rapidly and effectively absorbed, undergoes negligible metabolism and is a substrate for P-glycoprotein, which limits its passage across the blood-brain barrier. At the recommended dose of 20 mg, bilastine is non-sedative, does not enhance the effects of alcohol or CNS sedatives, does not impair actual driving tests, shows no cardiotoxicity and has a similar efficacy to other second-generation H(1)-antihistamines in the treatment of allergic rhinoconjunctivitis and urticaria. In view of its favorable pharmacological and clinical characteristics, bilastine is likely to have particular benefit in urticaria for which guidelines recommend increasing the dosage of H(1)-antihistamines up to fourfold if standard dosing is ineffective.

(Global Allergy and Asthma European Network) task force assessed the unwanted side-effects and potential dangers of first-generation H1-antihistamines by reviewing the literature (Medline and Embase) and performing a media audit of US coverage from 1996 to 2008 of accidents and fatal adverse events...... in which these drugs were implicated. RESULTS: First-generation H(1)-antihistamines, all of which are sedating, are generally regarded as safe by laypersons and healthcare professionals because of their long-standing use. However, they reduce rapid eye movement (REM)-sleep, impair learning and reduce work...... efficiency. They are implicated in civil aviation, motor vehicle and boating accidents, deaths as a result of accidental or intentional overdosing in infants and young children and suicide in teenagers and adults. Some exhibit cardiotoxicity in overdose. CONCLUSIONS: This review raises the issue of better...

Antihistamines suppress upregulation of histidine decarboxylase gene expression with potencies different from their binding affinities for histamine H1 receptor in toluene 2,4-diisocyanate-sensitized rats

Full Text Available Antihistamines inhibit histamine signaling by blocking histamine H1 receptor (H1R or suppressing H1R signaling as inverse agonists. The H1R gene is upregulated in patients with pollinosis, and its expression level is correlated with the severity of nasal symptoms. Here, we show that antihistamine suppressed upregulation of histidine decarboxylase (HDC mRNA expression in patients with pollinosis, and its expression level was correlated with that of H1R mRNA. Certain antihistamines, including mepyramine and diphenhydramine, suppress toluene-2,4-diisocyanate (TDI-induced upregulation of HDC gene expression and increase HDC activity in TDI-sensitized rats. However, d-chlorpheniramine did not demonstrate any effect. The potencies of antihistamine suppressive effects on HDC mRNA elevation were different from their H1R receptor binding affinities. In TDI-sensitized rats, the potencies of antihistamine inhibitory effects on sneezing in the early phase were related to H1R binding. In contrast, the potencies of their inhibitory effects on sneezing in the late phase were correlated with those of suppressive effects on HDC mRNA elevation. Data suggest that in addition to the antihistaminic and inverse agonistic activities, certain antihistamines possess additional properties unrelated to receptor binding and alleviate nasal symptoms in the late phase by inhibiting synthesis and release of histamine by suppressing HDC gene transcription.

[Treatment of chronic idiopathic urticaria unresponsive to type 1 antihistamines in monotherapy].

The chronic idiopathic urticaria treatment is a difficult and often frustrating problem for physicians. Due to the lack of definitive medical therapeutic programs to relieve the symptoms and prevent from their recurrence, several pharmacologic approaches to the management of chronic idiopathic urticaria are proposed. The chronic urticaria pharmacologic therapy is therefore fit to abrogate effects of histamine and other mediators on cutaneous vasculature and inflammatory cells that participate in the pathogenesis of the urticaria. The most common approach is to avoid all aggravating factors and to block histamine. The mainstay therapy is the H1 antihistamines. A significant number of patients may remain unresponsive even after an increase in the dose or a change in the type of H1 antihistaminic drug. In these cases, several therapies can be associated: combinations of H1 antihistamines, nonsedating one tablet (morning) and one sedating (evening), this approach is very usual but no study has confirmed it rational; addition an H2 antagonist to the previous treatment for some patients may improve control of their symptoms; alternatively, the tricyclic antidepressant, Doxepin is usually prescribed. The results of other drugs reported in the literature is unpredictable, to include them in a strategy therapy. The results with Badrenergic agents, nifedipine, ketotifen, leukotriene antagonists and tranexamic acid are variable and don't appear better than those with H1 antagonists. The efficiency of danazol has to be confirmed by other controlled studies. Warfarin, sulfasalazine and ultraviolet radiation have been used apparently successfully, but no controlled study has been published. Only when the above treatments have failed then immunosuppresive therapies, intravenous immunoglobulin and plasmapheresis can be proposed for chronic idiopathic urticaria.

Full Text Available Inveterate actinic dermatitis is an immunologically mediated photodermatosis characterized by itchy eczematous dermhelminthiasis exposed to sunlight. The disease proceeds in the same way as the atopic eczema or atopic dermatitis. The treatment of patients with inveterate actinic dermatitis is similar to the treatment of patients with atopic dermatitis and eczema. Administration of the modern antihistaminic preparation desloratadine (Aerius in the treatment has a positive effect on the skin process relief and on some cellular and humoral immunity factors.

H1 antihistamines in allergic rhinitis: The molecular pathways of interleukin and toll - like receptor systems

Full Text Available The complex interaction between inflammatory mediators in allergic rhinitis (AR is determined by the role of genetic polymorphisms, including interleukin (IL and toll-like receptor (TLR genes. This study aimed to discuss the effects of H1-antihistamines on IL and TLR systems. Several ILs involved in AR pathogenesis are: IL-4 (rs2243250, rs1800925, rs1801275, rs2227284, rs2070874, IL-6 (rs1800795, rs1800797, IL-10 (rs1800871, rs1800872, IL-12R (rs438421, IL-13 (rs1800925, rs20541, IL-17 (rs3819024, IL-18 (rs360721, rs360718, rs360717, rs187238, IL-23R (rs7517847, and IL-27 (rs153109, rs17855750. In the IL system, histamines stimulate the IL production in Type 2 helper T (Th2 cells through protein kinase A (PKA, janus kinase-signal transducer and activator of transcription (JAK-STAT pathway, and the activation of H1-histamine receptor and histidine decarboxylase (HDC genes. On contrary, antihistamines down-regulate the H1-histamine receptor gene expression through the transcription suppression of HDC and IL genes and suppress histamine basal signaling through the inverse agonistic activity. TLRs involved in AR pathogenesis are TLR2 (rs4696480, rs3804099, rs5743708, TLR4 (rs4986790, TLR6 (rs2381289, TLR7 (rs179008, rs5935438, TRL8 (rs2407992, rs5741883, rs17256081, rs4830805, rs3788935, rs178998, and TLR10 (rs11466651. In the TLR system, histamines trigger the TLR expression by stimulating interferon-γ (IFN-γ to up-regulate mast cells and by stimulating receptor-interacting protein (RIP to activate IκB kinase-β. Contrastingly, antihistamines suppress TIR-domain-containing adaptor protein inducing IFN-β (TRIF and RIP protein and thus inhibit the expression of TLR. In addition, several studies indicated that H1-antihistamines inhibit the IL and TLR systems indirectly.

ASTERIA I was a 40-week, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of subcutaneous omalizumab as add-on therapy for 24 weeks in patients with chronic idiopathic urticaria/spontaneous urticaria (CIU/CSU) who remained symptomatic despite H1 antihistamine treatment at licensed doses. Patients aged 12–75 years with CIU/CSU who remained symptomatic despite treatment with approved doses of H1 antihistamines were randomized (1:1:1:1) in a double-blind manner to subcutaneous omalizumab 75 mg, 150 mg, or 300 mg or placebo every 4 weeks for 24 weeks followed by 16 weeks of follow-up. The primary end point was change from baseline in weekly itch severity score (ISS) at week 12. Among randomized patients (N=319: placebo n=80, omalizumab 75 mg n=78, 150 mg n=80, 300 mg n=81), 262 (82.1%) completed the study. Compared with placebo (n=80), mean weekly ISS was reduced from baseline to week 12 by an additional 2.96 points (95% confidence interval (CI): −4.71 to −1.21; P=0.0010), 2.95 points (95% CI: −4.72 to −1.18; P=0.0012), and 5.80 points (95% CI: −7.49 to −4.10; Pomalizumab 75-mg (n=77), 150-mg (n=80), and 300-mg groups (n=81), respectively. The omalizumab 300-mg group met all nine secondary end points, including a significant decrease in the duration of time to reach minimally important difference response (⩾5-point decrease) in weekly ISS (Pomalizumab 75-mg, 150-mg, 300-mg, and placebo groups, respectively, experienced a serious adverse event. Omalizumab 300 mg administered subcutaneously every 4 weeks reduced weekly ISS and other symptom scores versus placebo in CIU/CSU patients who remained symptomatic despite treatment with approved doses of H1 antihistamines.

The main purpose of the present study was to test the hypothesis that the depressed lung growth attributable to prenatal exposure to polycyclic aromatic hydrocarbons (PAH) may be modified by the intake of antihistamine medications. Individual prenatal PAH exposure was assessed by personal air monitoring in 176 children who were followed over nine years, in the course of which outdoor residential air monitoring, allergic skin tests for indoor allergens, lung function tests (FVC, FEV(1), FEV(05), and FEF(25-75)) were performed. The analysis with the General Estimated Equation (GEE) showed no association between prenatal PAH exposure and lung function in the group of children who were reported to be antihistamine users. However, in the group of antihistamine non-users all lung function tests except for FEF(25-75) were significantly and inversely associated with prenatal airborne PAH exposure. The results of the study suggest that the intake of antihistamine medications in early childhood may inhibit the negative effect of fetal PAH exposure on lung growth and provides additional indirect evidence for the hypothesis that lung alterations in young children resulting from PAH exposure may be caused by the allergic inflammation within lung. © 2014 Wiley Periodicals, Inc.

Many physicians believe that the most effective way to treat chronic urticaria is to take a nonsedating second-generation H1 -antihistamine in the morning and a sedating first-generation H1 -antihistamine, usually hydroxyzine, at night to enhance sleep. But is this belief well founded? To test this belief by comparing the effectiveness and prevalence of unwanted sedative effects when treating patients with chronic spontaneous urticaria (CSU) with levocetirizine 15 mg daily plus hydroxyzine 50 mg at night (levocetirizine plus hydroxyzine) vs. levocetirizine 20 mg daily (levocetirizine monotherapy). In this randomized, double-blind, cross-over study, 24 patients with difficult-to-treat CSU took levocetirizine plus hydroxyzine or levocetirizine monotherapy for periods of 5 days each. At the end of each treatment period, assessments were made of quality of life (Chronic Urticaria Quality of Life Questionnaire, CU-Q2 oL), severity of urticaria symptoms (Urticaria Activity Score, UAS), sleep disturbance during the night and daytime somnolence. Both treatments significantly decreased UAS, night-time sleep disturbances and CU-Q2 oL scores (P generation H1 -antihistamine, usually hydroxyzine, at night is not supported. These results are in line with the urticaria guidelines, which state that first-line treatment for urticaria should be new-generation, nonsedating H1 -antihistamines only. © 2014 The Authors.

Filoviruses, consisting of Ebola virus, Marburg virus and Cuevavirus, cause severe hemorrhagic fevers in humans with high mortality rates up to 90%. Currently, there is no approved vaccine or therapy available for the prevention and treatment of filovirus infection in humans. The recent 2013-2015 West African Ebola epidemic underscores the urgency to develop antiviral therapeutics against these infectious diseases. Our previous study showed that GPCR antagonists, particularly histamine receptor antagonists (antihistamines) inhibit Ebola and Marburg virus entry. In this study, we screened a library of 1220 small molecules with predicted antihistamine activity, identified multiple compounds with potent inhibitory activity against entry of both Ebola and Marburg viruses in human cancer cell lines, and confirmed their anti-Ebola activity in human primary cells. These small molecules target a late-stage of Ebola virus entry. Further structure-activity relationship studies around one compound (cp19) reveal the importance of the coumarin fused ring structure, especially the hydrophobic substituents at positions 3 and/or 4, for its antiviral activity, and this identified scaffold represents a favorable starting point for the rapid development of anti-filovirus therapeutic agents.

Effects of antihistamine on up-regulation of histamine H1 receptor mRNA in the nasal mucosa of patients with pollinosis induced by controlled cedar pollen challenge in an environmental exposure unit

Full Text Available In the present study, we examined the effects of antihistamine on the up-regulation of H1R mRNA in the nasal mucosa of patients with pollinosis induced by controlled exposure to pollen using an environmental exposure unit. Out of 20 patients, we designated 14 responders, whose levels of H1R mRNA in the nasal mucosa were increased after the first pollen exposure and excluded 6 non-responders. Accordingly, the first exposure to pollen without treatment significantly induced both nasal symptoms and the up-regulation of H1R mRNA in the nasal mucosa of the responders. Subsequently, prophylactic administration of antihistamine prior to the second pollen exposure significantly inhibited both of the above effects in the responders. Moreover, the nasal expression of H1R mRNA before the second pollen exposure in the responders pretreated with antihistamine was significantly decreased, as compared with that before the first pollen exposure without treatment. These findings suggest that antihistamines suppressed histamine-induced transcriptional activation of H1R gene in the nasal mucosa, in addition to their blocking effect against histamine on H1R, resulting in a decrease of nasal symptoms. These findings further suggest that by their inverse agonistic activity, antihistamines suppress the basal transcription of nasal H1R in the absence of histamine in responders.

The patients recorded dynamic changes in clinical symptoms of the disease (number of urticarial components, skin itching intensity, availability or absence of urticarial derniographism, angioedema signs and signs of the shortness of breath and reduced blood pressure in their individual diaries. Baseline signs of the patients’ cognitive condition and those recorded during the treatment were studied using the Kraepelin’s arithmetic test (modified by Schulte, I.M. Lushchikhina’s verbal and visual thinking assessment method and method for memorizing ten words. The control group comprised 31 subjects without chronic urticaria. Results of the study. Ebastine and Fexofenadine are the most efficient antihistamine drugs for the treatment of chronic urticaria. At the same time, they do not have any negative effect on the patients’ cognitive functions so they can be recommended for long-term treatment of chronic urticaria. In spite of its evident positive therapeutic effect, Cetirizine reduces mental alertness and deteriorates thinking in patients with chronic urticaria. Because of this, the drug must be prescribed with care for long-term administration to those patients whose professional activities demand increased attention concentration. Loratadine has a positive effect on the patients’ attention and thinking. However, taking into consideration its low efficacy, the drug can be prescribed as the basis therapy for the treatment of light forms of chronic urticaria.

In a randomized, double-blind, placebo-controlled trial involving 518 infants and children who had otitis media with effusion ("secretory" otitis media), we evaluated the efficacy of a two-week course of amoxicillin (40 mg per kilogram of body weight per day) with and without a four-week course of an oral decongestant-antihistamine combination. Among the 474 subjects who were evaluated at the four-week end point, the rate of resolution of middle-ear effusion was twice as high in those treated with amoxicillin, either with or without the decongestant-antihistamine, as in those who received placebo (P less than 0.001), but 69.8 percent of the amoxicillin-treated subjects still had effusion. Among both the amoxicillin-treated subjects and the placebo-treated subjects, resolution was more likely in those with initially unilateral effusion, in those who had had effusion for eight weeks or less, and in those without an upper respiratory tract infection at the four-week end point. Side effects were reported more often in subjects who received decongestant-antihistamine than in those who did not. Among the subjects without effusion at the four-week end point, recurrent effusion developed in approximately half those in both the amoxicillin and placebo groups during the subsequent three months. We conclude that in infants and children with otitis media with effusion, amoxicillin treatment increases to some extent the likelihood of resolution.

H1-antihistamines in pregnancy and lactation.

2002-01-01

Antihistamines may be used for the treatment of allergic rhinitis, upper respiratory infections, urticaria/angioedema, atopic dermatitis, and, rarely, as adjunctive treatment for anaphylaxis, during pregnancy. Because these illnesses may affect maternal comfort and safety as well as threaten the fetus directly (anaphylaxis) or indirectly, they often require therapy during pregnancy. Based on the information available to date, in this chapter we have attempted to provide rational guidelines for the gestational use of H1-receptor antagonists in a manner that will lead to the optimal well-being of both the mother and her infant. As more information becomes available, the recommendations herein may require modification. Although this chapter has dealt specifically with gestational management, a case can be made for considering this information when making therapeutic decisions in all women of childbearing potential. First, most pregnancies are unplanned, and the peak period of fetal vulnerability to drug-induced teratogenesis begins the day a woman's period is due. Second, during gestation, substantial alterations in a previously successful but not optimal-for-pregnancy chronic therapeutic regimen may be psychologically threatening to the patient and may lead to either uncontrolled disease or unanticipated side effects. Thus, pregnancy-appropriate regimens should ideally be discussed with all women of childbearing age as part of the informed therapeutic decision-making process.

We describe infusion-related reactions to infliximab (during infusion or within 1 hour postinfusion) in patients with active rheumatoid arthritis (RA) treated in a quaternary care center. We followed 113 patients for a mean of 60.6 +/- 28.9 weeks, obtaining 10.5 +/- 4.9 infusions per patient. We observed 1183 infusions resulting in 104 infusion reactions (8.8%). All reactions resolved within several hours following cessation of the infusion and none was serious enough to warrant hospitalization. Reactions included allergic reactions (pruritus, urticaria) in 4.2% of infusions, cardiopulmonary (hypotension, hypertension, tachycardia) in 3.0%, and miscellaneous reactions (headache, nausea, vomiting) in 2.0%. Reactions occurred in 8.0% of 3 mg/kg infusions and in 10.3% of 5 mg/kg infusions. Reactions occurred in 13.2% of infusions that involved antihistamine pretreatment compared to only 7.5% of infusions that involved no pretreatment. At both infliximab doses, there was a similar frequency of infusion reactions in patients pretreated due to a previous infusion (12.6%) compared to those pretreated strictly based on infusion number (14.7%). A number of the reactions involving antihistamine pretreatment may be explained by known side effects of diphenhydramine, including headache, dizziness, nausea, and palpitations. Infusion-related reactions to infliximab were infrequent, rarely severe, and easily manageable. The frequency of reactions was equivalent in patients treated with 3 mg/kg compared to 5 mg/kg. Reactions were significantly more frequent in infusions where patients were pretreated with the antihistamine diphenhydramine, compared to those not involving pretreatment.

In a double-blind, randomized trial of 553 infants and children who had otitis media with effusion ("secretory" otitis media), we compared the efficacy of a four-week course of an oral decongestant-antihistamine combination (pseudoephedrine hydrochloride, 4 mg per kilogram of body weight per day, and chlorpheniramine maleate, 0.35 mg per kilogram per day) with that of placebo. Among patients with initially unilateral disease, resolution of middle-ear effusion occurred at four weeks in 38 per cent of those treated with placebo and 34 per cent of those treated with drug (P = 0.74). Among patients with initially bilateral disease the corresponding proportions were 19 and 21 per cent, respectively (P = 0.67). Side effects were reported more often among drug-treated than placebo-treated patients. Decongestant-antihistamine combinations do not appear to be indicated for the treatment of otitis media with effusion in infants and children.

The aim of this study was to evaluate anticholinergic, antihistaminic, and antiserotonergic activity of the n-hexane extract of the seeds of Zanthoxylum alatum (ZAHE) on isolated ileum of rat and guinea pig and fundus of rat. ZAHE was prepared using soxhlet extraction and cumulative concentration response curves were constructed using various doses on the tissues for acetylcholine (ACh), 5-hydroxytryptamine (5-HT), and histamine with or without n-hexane extract. Atropine, ketanserin, and pheniramine maleate were used as antagonists for ACh, serotonin, and histamine, respectively. ZAHE-induced concentration-dependent inhibition of isolated ileum and fundus in rat and ileum of guinea pig. The half maximal effective concentration (EC 50 ) of ACh in the presence of atropine (10 -6 M; P pheniramine maleate (10 -6 M; P < 0.01) and ZAHE (300 μg/ml; P < 0.01 and 1000 μg/ml; P < 0.05) was also significantly higher than EC 50 of histamine alone. From the study, it was observed that ZAHE shows significant anticholinergic, antiserotonergic, and antihistaminic activity. The study provides sufficient evidence that the seeds can be used in gastric disorders, cough, chest infection, etc., as per folklore claims.

Pollen forecasts are in use everywhere to inform therapeutic decisions for patients with allergic rhinoconjunctivitis (ARC). We exploited data derived from Twitter in order to identify tweets reporting a combination of symptoms consistent with a case definition of ARC and those reporting the name of an antihistamine drug. In order to increase the sensitivity of the system, we applied an algorithm aimed at automatically identifying jargon expressions related to medical terms. We compared weekly Twitter trends with National Allergy Bureau weekly pollen counts derived from US stations, and found a high correlation of the sum of the total pollen counts from each stations with tweets reporting ARC symptoms (Pearson's correlation coefficient: 0.95) and with tweets reporting antihistamine drug names (Pearson's correlation coefficient: 0.93). Longitude and latitude of the pollen stations affected the strength of the correlation. Twitter and other social networks may play a role in allergic disease surveillance and in signaling drug consumptions trends.

Full Text Available The electrochemical oxidation of an antihistamine drug, methdilazine, was studied in 9.2 pH with 0.2 M phosphate buffer as supporting electrolyte at 25 ± 0.2°C. Glassy carbon electrode was used to perform the experiment at cyclic voltammetry, linear sweep voltammetry and differential pulse voltammetric techniques. The dependence of the current on pH, concentration and scan rate were investigated. Differential pulse voltammetric technique was adopted to know the linear relation between peak current and methdilazine concentration. The linear response was obtained in the range of 3.0 μM–1.0 mM with a detection limit of 0.1 μM. The proposed method was also applied for the quantitative determination of methdilazine in pharmaceuticals and biological samples.

Unwanted side effects such as dryness, hypersensitivity, and cutaneous photosensitivity are challenge for adherence and therapeutical success for patients using treatments for inflammatory and allergic skin response. In this study, we compared the effects of two dermatological formulations, which are used in inflammatory and/or allergic skin conditions: dexchlorpheniramine maleate (DCP; 10 mg/g) and promethazine (PTZ; 20 mg/g). We evaluated both formulations for phototoxicity potential, skin irritation, anti-inflammatory and antihistaminic abilities, and skin barrier repair in vitro and ex vivo using the standard OECD test guideline n° 432, the ECVAM protocol n° 78, and cultured skin explants from a healthy patient. Ultraviolet A was chosen as exogenous agent to induce allergic and inflammatory response. Both PTZ and DCP promoted increases in interleukin-1 (IL-1) synthesis in response to ultraviolet A (UVA) radiation compared to control. However, the increase observed with PTZ was significantly greater than the DCP, indicating that the latter has a lower irritant potential. DCP also demonstrated a protective effect on UVA-induced leukotriene B4 and nuclear factor kappa B (NF-κB) synthesis. Conversely, PTZ demonstrates more robust UVA antihistaminic activity. Likewise, PTZ promoted a significantly greater increase in the production of involucrin and keratin 14, both associated with protective skin barrier property. In conclusion, these data suggest possible diverging UVA response mechanisms of DCP and PTZ, which gives greater insight into the contrasting photosensitizing potential between DCP and PTZ observed in the patients. © 2017 Wiley Periodicals, Inc.

A rapid and efficient dual preconcentration method of on-line single drop liquid-liquid-liquid microextraction (SD-LLLME) coupled to sweeping micellar electrokinetic chromatography (MEKC) was developed for trace analysis of three antihistamines (mizolastine, chlorpheniramine and pheniramine) in human urine. Three analytes were firstly extracted from donor phase (4 mL urine sample) adjusted to alkaline condition (0.5 M NaOH). The unionized analytes were subsequently extracted into a drop of n-octanol layered over the urine sample, and then into a microdrop of acceptor phase (100 mM H(3)PO(4)) suspended from a capillary inlet. The enriched acceptor phase was on-line injected into capillary with a height difference and then analyzed directly by sweeping MEKC. Good linear relationships were obtained for all analytes in a range of 6.25 × 10(-6) to 2.5 × 10(-4)g/L with correlation coefficients (r) higher than 0.987. The proposed method achieved limits of detections (LOD) varied from 1.2 × 10(-7) to 9.5 × 10(-7)g/L based on a signal-to-noise of 3 (S/N=3) with 751- to 1372-fold increases in detection sensitivity for analytes, and it was successfully applied to the pharmacokinetic study of three antihistamines in human urine after an oral administration. The results demonstrated that this method was a promising combination for the rapid trace analysis of antihistamines in human urine with the advantages of operation simplicity, high enrichment factor and little solvent consumption.

In the present study, artificial neural networks (ANNs) and least squares support vector machines (LS-SVM) as intelligent methods based on absorption spectra in the range of 230-300 nm have been used for determination of antihistamine decongestant contents. In the first step, one type of network (feed-forward back-propagation) from the artificial neural network with two different training algorithms, Levenberg-Marquardt (LM) and gradient descent with momentum and adaptive learning rate back-propagation (GDX) algorithm, were employed and their performance was evaluated. The performance of the LM algorithm was better than the GDX algorithm. In the second one, the radial basis network was utilized and results compared with the previous network. In the last one, the other intelligent method named least squares support vector machine was proposed to construct the antihistamine decongestant prediction model and the results were compared with two of the aforementioned networks. The values of the statistical parameters mean square error (MSE), Regression coefficient (R2), correlation coefficient (r) and also mean recovery (%), relative standard deviation (RSD) used for selecting the best model between these methods. Moreover, the proposed methods were compared to the high- performance liquid chromatography (HPLC) as a reference method. One way analysis of variance (ANOVA) test at the 95% confidence level applied to the comparison results of suggested and reference methods that there were no significant differences between them.

Full Text Available Chronic spontaneous urticaria (CSU affects 1% of the world population and also their quality of life, and 50% of these patients are refractory to H1-antihistamines. Omalizumab is a humanized monoclonal anti-IgE antibody that binds with free IgE antibodies and reduces the circulating levels of free IgE. This reduction in free IgE prevents mast-cell degranulation. The EAACI/GA2LEN/EDF/WAO guidelines recommend omalizumab as the third-line of therapy as an add-on to antihistamines. The recommended dose of omalizumab is 300 mg, 4 weekly in the management of CSU refractory to standard of care with H1-antihistamines in adults and adolescents ≥12 years of age. In some patients, a dose of 150 mg may be acceptable. Omalizumab has a good safety profile. However, due to the biologic nature of the drug, all patients administered omalizumab must be observed for 2 h after administration for anaphylactoid reactions. There have been no studies on the effect of impaired renal or hepatic function on the pharmacokinetics of omalizumab. While no particular dose adjustment is recommended, omalizumab should be administered with caution in these patients.

Seasonal changes in the concentration of 21 pharmaceuticals in a wastewater treatment plant (WWTP) in České Budějovice were investigated over 12months. The target compounds were 10 antibiotics, 4 antidepressants, 3 psychiatric drugs, 2 antihistamines and 2 lipid regulators. 272 Wastewater samples (136 influents and 136 effluents) were collected from March 2011 to February 2012 and analyzed using two-dimensional liquid chromatography coupled with tandem mass spectrometry. All studied pharmaceuticals were frequently detected in both the influent and the effluent wastewater samples, except for meclozine, which was only found in the influent. The mean concentration of pharmaceuticals varied from 0.006μgL(-1) to 1.48μgL(-1) in the influent and from 0.003μgL(-1) to 0.93μgL(-1) in the effluent. The concentration of most pharmaceuticals was higher during winter. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available Osmo Kari1, K Matti Saari21Department of Allergology, Skin and Allergy Hospital, Helsinki University Central Hospital, Helsinki, Finland; 2Department of Ophthalmology, University of Turku, Turku, FinlandAbstract: Allergic diseases have greatly increased in industrialized countries. About 30% of people suffer from allergic symptoms and 40%–80% of them have symptoms in the eyes. Atopic conjunctivitis can be divided into seasonal allergic conjunctivitis (SAC and perennial allergic conjunctivitis (PAC. The treatment of SAC is simple; antihistamines, anti-inflammatory agents, or chromoglycate. In severe cases of SAC, subcutaneous or sublingual immunotherapy is helpful. PAC needs longer therapy, often year round, with mast cell stabilizers, antihistamines, and sometimes local steroids. Atopic keratoconjunctivitis is a more severe disease showing chronic blepharitis often connected with severe keratitis. It needs, in many cases, continuous treatment of the lid eczema and keratoconjunctivitis. Blepharitis is treated with tacrolimus or pimecrolimus ointment. Conjunctivitis additionally needs corticosteroids and, if needed, cyclosporine A (CsA drops are administered for longer periods. Basic conjunctival treatment is with mast cell-stabilizing agents and in addition, antihistamines are administered. Vernal keratoconjunctivitis is another chronic and serious allergic disease that mainly affects children and young people. It is a long-lasting disease which commonly subsides in puberty. It demands intensive therapy often for many years to avoid serious complicating corneal ulcers. Treatment is mast cell-stabilizing drops and additionally antihistamines. In relapses, corticosteroids are needed. When the use of corticosteroids is continuous, CsA drops should be used, and in relapses, corticosteroids should be used additionally.

2013-02-01

Full Text Available Abstract Background Bixa orellana L. has been traditionally used in Central and South America to treat a number of ailments, including internal inflammation, and in other tropical countries like Malaysia as treatment for gastric ulcers and stomach discomfort. The current study aimed to determine the major chemical constituents of the aqueous extract of B. orellana (AEBO and to evaluate the antihistamine activity of AEBO during acute inflammation induced in rats. Methods Acute inflammation was produced by subplantar injection of 0.1 mL of 0.1% histamine into the right hind paw of each rat in the control and treatment groups. The degree of edema was measured before injection and at the time points of 30, 60, 120, 180, 240 and 300 min after injection. Changes of peritoneal vascular permeability were studied using Evans blue dye as a detector. Vascular permeability was evaluated by the amount of dye leakage into the peritoneal cavity in rats. To evaluate the inhibitory effect of AEBO on biochemical mediators of vascular permeability, the levels of nitric oxide (NO and vascular endothelial growth factor (VEGF were determined in histamine-treated paw tissues. The major constituents of AEBO were determined by gas chromatography–mass spectrometry (GC-MS analysis. Results AEBO produced a significant inhibition of histamine-induced paw edema starting at 60 min time point, with maximal percentage of inhibition (60.25% achieved with a dose of 150 mg/kg of AEBO at 60 min time point. Up to 99% of increased peritoneal vascular permeability produced by histamine was successfully suppressed by AEBO. The expression of biochemical mediators of vascular permeability, NO and VEGF, was also found to be downregulated in the AEBO treated group. Gas chromatography–mass spectrometry (GC-MS analysis revealed that the major constituent in AEBO was acetic acid. Conclusions The experimental findings demonstrated that the anti-inflammatory activity of AEBO was

Can human allergy drug fexofenadine, an antagonist of histamine (H1) receptor, be used to treat dog and cat? Homology modeling, docking and molecular dynamic Simulation of three H1 receptors in complex with fexofenadine.

Fexofenadine, a potent antagonist to human histamine 1 (H 1 ) receptor, is a non-sedative third generation antihistamine that is widely used to treat various human allergic conditions such as allergic rhinitis, conjunctivitis and atopic dermatitis. Encouragingly, it's been successfully used to treat canine atopic dermatitis, this supports the notion that it might have a great potential for treating other canine allergic conditions and other mammal pets such as dog. Regrettably, while there is a myriad of studies conducted on the interactions of antihistamines with human H 1 receptor, the similar studies on non-human pet H 1 are considerably scarce. The published studies using the first and second generation antihistamines drugs have shown that the antihistamine response is varied and unpredictable. Thus, to probe its efficacy on pet, the homology models of dog and cat H 1 receptors were built based on the crystal structure of human H 1 receptor bound to antagonist doxepin (PDB 3RZE) and fexofenadine was subsequently docked to human, dog and cat H 1 receptors. The docked complexes are then subjected to 1000ns molecular dynamics (MD) simulations with explicit membrane. Our calculated MM/GBSA binding energies indicated that fexofenadine binds comparably to the three receptors; and our MD data also showed the binding poses, structural and dynamic features among three receptors are very similar. Therefore, our data supported the application of fexofenadine to the H 1 related allergic conditions of dog and cat. Nonetheless, subtle systemic differences among human, dog and cat H 1 receptors were also identified. Clearly, there is still a space to develop a more selective, potent and safe antihistamine alternatives such as Fexofenadine for dog or cat based on these differences. Our computation approach might provide a fast and economic way to predict if human antihistamine drugs can also be safely and efficaciously administered to animals. Copyright © 2017 Elsevier Inc

McKeirnan, Kimberly C; Frazier, Kyle R; Nguyen, Maryann; MacLean, Linda Garrelts

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.

Antihistamines are a mainstay treatment for allergic rhinitis; however, many older agents cause adverse events, including sedation and central nervous system (CNS) impairment. Research has shown sedating effects of antihistamines on driving; currently, no known study has examined whether cellular phone usage while driving further compounds impairment in individuals administered antihistamines. The aim of this study was to examine this endpoint. In a randomized, double-blind, placebo-controlled, three-way crossover study, healthy volunteers received fexofenadine HCl 120 mg, hydroxyzine HCl 30 mg and placebo. Brake reaction time (BRT) was used to examine driving performance across four conditions: driving only; driving while completing simple calculations; complex calculations; and conversing on a cellular phone. Subjective sedation assessments were also conducted. Brake reaction time with and without cellular phone usage in fexofenadine-treated subjects did not differ significantly from placebo in any condition. In contrast, hydroxyzine-treated subjects were significantly more sedated and had slower BRTs, suggesting slower hazard recognition and brake application, compared with the fexofenadine and placebo groups in all conditions. Importantly, cellular phone operation was an additive factor, increasing BRTs in hydroxyzine-treated volunteers. Fexofenadine did not impair CNS function in subjects involved in a divided attention task of driving and cellular phone operation. Copyright (c) 2005 John Wiley & Sons, Ltd.

Nakamura, Mototoshi; Koga, Sukehiko; Kondo, Takeshi

1993-01-01

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

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.

1983-01-01

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

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

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

1. The possible interaction between a new H1 antihistamine, mizolastine, and lorazepam was assessed in a randomised, double-blind, cross-over, placebo-controlled study involving 16 healthy young male volunteers who received mizolastine 10 mg or placebo once daily for 8 days with a 1 week wash-out interval. The interaction of mizolastine, at steady-state, with a single oral dose of lorazepam or placebo was assessed on days 6 or 8 of each treatment period. 2. Psychomotor performance and cognitive function were evaluated using objective tests (critical flicker fusion threshold, choice reaction time, tapping, arithmetic calculation, body sway) and self-ratings (visual analogue scale, ARCI) before and at 2, 4, 6 and 8 h after dosing. Short-term memory (Sternberg memory scanning immediate free recall of a word list) and long-term memory (delayed free recall and recognition of words and pictures) were assessed before and at 3 h after dosing. Pharmacodynamic interactions were evaluated by repeated measures ANOVA in a 2 x 2 factorial interaction model. 3. Mizolastine, 10 mg once daily, at steady-state, was devoid of sedation and detrimental effect on skilled performance and memory. 4. In contrast, a single 2 mg dose of lorazepam produced marked impairment of psychomotor performance, cognitive functions (significant reduction in flicker fusion threshold, tapping and arithmetic calculation and increase in reaction times and body sway) and subjective sedation from 2 to 8 h after dosing. In addition, lorazepam induced an anterograde amnesia, characterised by a decrease in delayed free recall and recognition, and a deficit in short term memory.(ABSTRACT TRUNCATED AT 250 WORDS)

In an attempt to elucidate mechanisms underlying the irradiation-induced decrease in regional cerebral blood flow (rCBF) in primates, hippocampal and visual cortical blood flows of rhesus monkeys were measured by hydrogen clearance, before and after exposure to 100 Gy, whole-body, gamma irradiation. Systemic blood pressures were monitored simultaneously. Systemic arterial plasma histamine and neurotensin levels were determined preirradiation and postirradiation. Compared to control animals, the irradiated monkeys exhibited an abrupt decline in systemic blood pressure to 23% of the preirradiation level within 10 min postirradiation, falling to 12% by 60 min. A decrease in hippocampal blood flow to 32% of the preirradiation level was noted at 10 min postirradiation, followed by a slight recovery to 43% at 30 min and a decline to 23% by 60 min. The cortical blood flow for the same animals showed a steady decrease to 29% of the preirradiation levels by 60 min postirradiation. Animals given the mast cell stabilizer disodium cromoglycate and the antihistamines mepyramine and cimetidine before irradiation did not exhibit an abrupt decline in blood pressure but displayed a gradual decrease to a level 33% below preirradiation levels by 60 min postirradiation. Also, the treated, irradiated monkeys displayed rCBF values that were not significantly different from the nonirradiated controls. The plasma neurotensin levels in the irradiated animals, treated and untreated, indicated a nonsignificant postirradiation increase above control levels. However, the postirradiation plasma histamine levels in both irradiated groups showed an increase of approximately 1600% above the preirradiation levels and the postirradiation control levels

Allergic rhinitis, also known as hay fever, rose fever or summer catarrh, is a major challenge to health professionals. A large number of the world's population, including approximately 40 million Americans, suffers from allergic rhinitis. A novel, botanical formulation (Aller-7) has been developed for the treatment of allergic rhinitis using a combination of extracts from seven medicinal plants, including Phyllanthus emblica, Terminalia chebula, T. bellerica, Albizia lebbeck, Piper nigrum, Zingiber officinale and P. longum, which have a proven history of efficacy and health benefits. The clinical manifestations of allergy are due to a number of mediators that are released from mast cells. The effect of Aller-7 on rat mesenteric mast cell degranulation was studied by incubating different concentrations of Aller-7 and challenging them with a degranulating agent, compound 48/80. The inhibitory activity of Aller-7 was determined against lipoxygenase and hyaluronidase, the key enzymes involved in the initiation and maintenance of inflammatory responses. Furthermore, most of these manifestations are due to histamine, which causes vasodilatation, increasing capillary permeability and leading to bronchoconstriction. Hence, the antihistaminic activity of Aller-7 was determined is isolated guinea pig ileum substrate using cetirizine as a positive control. The antispasmodic effect of Aller-7 on contractions of guinea pig tracheal chain was determined using papaverine and cetirizine as controls. Aller-7 exhibited potent activity in all these in vitro models tested, thus demonstrating the novel anti-allergic potential of Aller-7.

A fully validated UHPLC method for the identification and quantification of pharmaceutical preparations, containing paracetamol and/or acetyl salicylic acid, combined with anti-histaminics (phenylephrine, pheniramine maleate, diphenhydramine, promethazine) and/or other additives as quinine sulphate, caffeine or codeine phosphate, was developed. The proposed method uses a Waters Acquity BEH C18 column (2 mm × 100 mm, 1.7 μm) with a gradient using an ammonium acetate buffer pH 4.0 as aqueous phase and methanol as organic modifier. The obtained method was fully validated based on its measurement uncertainty (accuracy profile) and robustness tests. Calibration lines for all components were linear within the studied ranges. The relative bias and the relative standard deviations for all components were respectively smaller than 1.5% and 2%, the β-expectation tolerance limits did not exceed the acceptance limits of 10% and the relative expanded uncertainties were smaller than 5% for all of the considered components. A UHPLC method was obtained for the identification and quantification of these kind of pharmaceutical preparations, which will significantly reduce analysis times and workload for the laboratories charged with the quality control of these preparations.

Full Text Available Belen Sadaba, Jose Ramon Azanza, Almundena Gomez-Guiu, Raquel RodilClinical Pharmacology Service, Clinica Universidad de Navarra, Navarra, SpainAbstract: Bilastine is a second generation antihistamine indicated for the treatment of seasonal or perennial allergic rhinoconjunctivitis and chronic urticaria with a daily dose of 20 mg, in adults and children over 12 years of age. The efficacy of bilastine has been shown to be similar to that of the comparator drugs for the control of the nasal and nonnasal symptoms of allergic rhinoconjunctivitis, while also showing a subjective improvement in the quality of life and in overall clinical impression. For chronic urticaria the symptoms (itching and the development of papules lessens from the second day of treatment onwards, in a similar way to other antihistamines used as comparators. Bilastine should not be administered at meal times to avoid interference with the absorption process. It is not distributed to the central nervous system, is scarcely metabolized, and elimination is through the kidneys and feces, with a 14-hour elimination half-life. It has no effect on cytochrome P450. During clinical development, bilastine was shown to be a drug that is adequately tolerated, with a similar effect to placebo with regard to drowsiness and changes in heart rate. In relation to its use, headaches were the most frequent adverse effect to be reported. No cardiotoxic effects have been observed, and the therapeutic dose does not alter the state of alertness.Keywords: bilastine, allergic rhinoconjunctivitis, chronic urticaria, second generation antihistamine, drowsiness, CYP450

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

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

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.

Chronic spontaneous urticaria (CSU) severely impacts quality of life (QoL), especially in patients with wheals and angioedema. Omalizumab is approved as add-on therapy for CSU patients; however, its effect on patients who are double-positive for wheals and angioedema has not been systematically studied. The primary objective was to evaluate the efficacy of omalizumab vs placebo at week 28 using the Chronic Urticaria Quality of Life (CU-Q2oL) questionnaire. Number of angioedema-burdened days, time interval between successive angioedema episodes, disease activity, angioedema-specific and overall QoL impairment were secondary objectives. X-ACT was a phase III, randomized, double-blind study conducted in 24 centres (Germany), which selectively included CSU patients with angioedema and wheals. Patients were randomized (1 : 1) to omalizumab 300 mg or placebo (every 4 weeks up to week 24) (ClinicalTrials.gov number: NCT01723072). Of the 91 patients randomized to omalizumab (n = 44) or placebo (n = 47) at baseline, 68 completed the 28-week treatment phase (omalizumab, 35; placebo, 33). Omalizumab was superior to placebo in improving CU-Q2oL scores at week 28 (P omalizumab (0.3) vs placebo (1.1). The median time to first recurrence of angioedema was 57-63 days with omalizumab and Omalizumab significantly improved angioedema-specific QoL (P omalizumab. Omalizumab was an effective treatment option for patients with moderate-to-severe CSU symptoms and angioedema unresponsive to high doses of antihistamine treatment. © 2016 John Wiley & Sons A/S.

2013-09-01

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

2010-06-01

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

Souza, Marcy J; Greenacre, Cheryl B; Cox, Sherry K

2008-08-01

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.

Lutwak, Nancy; Howland, Mary Ann; Gambetta, Rosemarie; Dill, Curt

2013-01-01

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

Disposal of wastes from radiopharmaceuticals administered in human body in hospital

International Nuclear Information System (INIS)

1976-01-01

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

CLINICAL AND PHARMACOLOGICAL PECULIARITIES OF CETIRIZINE USE FOR THE THERAPY OF ALLERGIC DISEASES IN CHILDREN

Directory of Open Access Journals (Sweden)

Yu. G. Levina

2014-01-01

Full Text Available The review is dedicated to treatment of allergic diseases in children, particularly to the use of the 2nd generation antihistamine. It demonstrates that mediator histamine has the crucial role in pathophysiology of the allergic reaction. Antihistamines block histamine action aimed at H1 receptors by way of competitive inhibition. The 2nd generation antihistamines are the drugs of choice for the treatment of allergic diseases due to the absence of sedative effect. The review presents clinical and pharmacological description of the selective 2nd generation antihistamine cetirizine, efficacy and safety of which have been appraised in numerous long-term clinical studies in children with allergic rhinitis, urticaria and atopic dermatitis.

Prevention of adverse reactions to intravascular contrast media

International Nuclear Information System (INIS)

Soyer, P.; Levesque, M.

1990-01-01

The exact mechanisms of adverse reactions to contrast media are still imperfectly known. However, these reactions may be classified as idiosyncratic. Non-idiosyncratic reactions can be prevented by using new, non-ionic contrast agents. Idiosyncratic reactions can be prevented by specific premedication. Patients with a history of idiosyncratic reaction may benefit from corticosteroids and antihistamines administered prophylactically. Patients who seem to be more likely than others to react to contrast media must be premedicated, the risk of reaction being identified and evaluated by questioning. It has recently been suggested that all patients about to receive an intravascular injection of contrast medium should also be premedicated [fr

Neuraxial opioid-induced pruritus: a review.

LENUS (Irish Health Repository)

Szarvas, Szilvia

2012-02-03

When intrathecal and epidural opioids are administered, pruritus occurs as an unwanted and troublesome side effect. The reported incidence varies between 30% and 100%. The exact mechanisms of neuraxial opioid-induced pruritus remain unclear. Postulated mechanisms include the presence of an "itch center" in the central nervous system, medullary dorsal horn activation, and antagonism of inhibitory transmitters. The treatment of intrathecal opioid-induced pruritus remains a challenge. Many pharmacological therapies, including antihistamines, 5-HT(3)-receptor antagonists, opiate-antagonists, propofol, nonsteroid antiinflammatory drugs, and droperidol, have been studied. In this review, we will summarize pathophysiological and pharmacological advances that will improve understanding and ultimately the management of this troublesome problem.

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

El-Masry, Amal A.; Hammouda, Mohammed E. A.; El-Wasseef, Dalia R.; El-Ashry, Saadia M.

2018-02-01

Two simple, sensitive, rapid, validated and cost effective spectroscopic methods were established for quantification of antihistaminic drug azelastine (AZL) in bulk powder as well as in pharmaceutical dosage forms. In the first method (A) the absorbance difference between acidic and basic solutions was measured at 228 nm, whereas in the second investigated method (B) the binary complex formed between AZL and Eosin Y in acetate buffer solution (pH 3) was measured at 550 nm. Different criteria that have critical influence on the intensity of absorption were deeply studied and optimized so as to achieve the highest absorption. The proposed methods obeyed Beer's low in the concentration range of (2.0-20.0 μg·mL- 1) and (0.5-15.0 μg·mL- 1) with % recovery ± S.D. of (99.84 ± 0.87), (100.02 ± 0.78) for methods (A) and (B), respectively. Furthermore, the proposed methods were easily applied for quality control of pharmaceutical preparations without any conflict with its co-formulated additives, and the analytical results were compatible with those obtained by the comparison one with no significant difference as insured by student's t-test and the variance ratio F-test. Validation of the proposed methods was performed according the ICH guidelines in terms of linearity, limit of quantification, limit of detection, accuracy, precision and specificity, where the analytical results were persuasive. The absorption spectrum of AZL (16 μg·mL- 1) in 0.1 M HCl. The absorption spectrum of AZL (16 μg·mL- 1) in 0.1 M NaOH.

Chronic Spontaneous Urticaria: Pathogenesis and Treatment Considerations.

Science.gov (United States)

Kaplan, Allen P

2017-11-01

The treatment of chronic spontaneous urticaria begins with antihistamines; however, the dose required typically exceeds that recommended for allergic rhinitis. Second-generation, relatively non-sedating H₁-receptor blockers are typically employed up to 4 times a day. First-generation antihistamines, such as hydroxyzine or diphenhydramine (Atarax or Benadryl), were employed similarly in the past. Should high-dose antihistamines fail to control symptoms (at least 50%), omalizumab at 300 mg/month is the next step. This is effective in 70% of antihistamine-refractory patients. H₂-receptor blockers and leukotriene antagonists are no longer recommended; they add little and the literature does not support significant efficacy. For those patients who are unresponsive to both antihistamines and omalizumab, cyclosporine is recommended next. This is similarly effective in 65%-70% of patients; however, care is needed regarding possible side-effects on blood pressure and renal function. Corticosteroids should not be employed chronically due to cumulative toxicity that is dose and time dependent. Brief courses of steroid e.g., 3-10 days can be employed for severe exacerbations, but should be an infrequent occurrence. Finally, other agents, such as dapsone or sulfasalazine, can be tried for those patients unresponsive to antihistamines, omalizumab, and cyclosporine.

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.

[COOP/WONCA: Reliability and validity of the test administered by telephone].

Pedrero-Pérez, Eduardo J; Díaz-Olalla, José Manuel

2016-01-01

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.

Central nervous system effects of the second-generation antihistamines marketed in Japan--review of inter-drug differences using the proportional impairment ratio (PIR-.

Directory of Open Access Journals (Sweden)

Tatsuya Isomura

Full Text Available BACKGROUND: Second-generation antihistamines (AHs have, in general, fewer sedative effects than the first-generation. However, important inter-drug differences remain in the degree of cognitive and/or psychomotor impairment. The extent to which a particular compound causes disruption can be conveniently compared, to all other AHs, using the Proportional Impairment Ratio (PIR. Although the PIR can differentiate the relative impairment caused by individual drugs, there is no indication of the reliability of the ratios obtained. OBJECTIVE: To calculate the PIRs -together with 95% confidence intervals (CIs, as an index of reliability- and compare AHs currently, or soon to be, available in Japan, with respect to their intrinsic capacity to cause impairment. METHODS: Results from studies of cetirizine, desloratadine, ebastine, fexofenadine, levocetirizine, loratadine, mequitazine, and olopatadine were included in the PIR calculations. All data utilised came from crossover studies in healthy volunteers which were randomised and placebo and positive-internal controlled. Existing databases from studies reporting the sedative effects of AHs on objective (speed, accuracy, memory and subjective (feeling psychometrics were augmented, via results from suitable studies published after the previous reviews. The null value for a PIR was one. RESULTS: A total of 45 studies were finally included for this review. Of the AHs assessed, fexofenadine, ebastine, and levocetirizine showed a PIR for objective tests of 0. However, only fexofenadine (PIR = 0.49 had an upper limit of the 95% CI of less than 1. Fexofenadine, levocetirizine, desloratadine, olopatadine, loratadine, and mequitazine all had a PIR for subjective ratings of 0, but the upper limits of the 95% CIs were all in excess of 1, although fexofenadine (PIR = 2.57 was the lowest. CONCLUSIONS: The results show that there are differences between second-generation AHs in the extent of sedation produced

Successful treatment of bullous lichen planus with acitretin monotherapy. Review of treatment options for bullous lichen planus and case report.

2016-12-31

Bullous lichen planus (BLP) is a rare variant of lichen planus, characterized by the development of vesicular and bullous lesions, of skin, nails, hair and/or mucosa. We present a case of 63-year-old woman with BLP, unresponsive to previous therapies with topical corticosteroids, topical calcipotriol, antihistamines and oral cyclosporine (4 mg/kg/day for 4 months). She was already receiving treatment for arterial hypertension, hyperlipidemia, atrial fibrillation and uncontrolled diabetes mellitus. Acitretin was administered for 5 months with complete remission of BLP lesions and no major side effects. This is probably the first reported case of BLP treated with acitretin monotherapy. In this case acitretin was an efficacious and well-tolerated therapeutic option for BLP.

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

Science.gov (United States)

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

2006-06-01

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

Disclosure of sensitive behaviors across self-administered survey modes: a meta-analysis.

Science.gov (United States)

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.

Shinohara, A.; Chiba, M.; Inaba, Y.

1998-01-01

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

Test-retest repeatability of child's respiratory symptoms and perceived indoor air quality - comparing self- and parent-administered questionnaires.

2018-02-09

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

Validation of a self-administered questionnaire for assessing occupational and environmental exposures of pregnant women

International Nuclear Information System (INIS)

Eskenazi, B.; Pearson, K.

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

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

DEFF Research Database (Denmark)

Friesgaard, Kristian Dahl; Nikolajsen, Lone; Giebner, Matthias

2016-01-01

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

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

Patient protection in nuclear medicine due to optimization of the administered activity

International Nuclear Information System (INIS)

Perez Diaz, M.; Diaz Rizo, O.; Khouri, H. J.

2011-01-01

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

Preclinical safety evaluation of intravenously administered mixed micelles.

Science.gov (United States)

Teelmann, K; Schläppi, B; Schüpbach, M; Kistler, A

1984-01-01

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

Can we safely administer the recommended dose of phenobarbital in very low birth weight infants?

Science.gov (United States)

Oztekin, Osman; Kalay, Salih; Tezel, Gonul; Akcakus, Mustafa; Oygur, Nihal

2013-08-01

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

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

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.

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

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

Opponent process properties of self-administered cocaine.

Science.gov (United States)

Ettenberg, Aaron

2004-01-01

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

Omalizumab for the Treatment of Chronic Idiopathic Urticaria: Systematic Review of the Literature.

Tonacci, Alessandro; Billeci, Lucia; Pioggia, Giovanni; Navarra, Michele; Gangemi, Sebastiano

2017-04-01

Omalizumab is recombinant humanized monoclonal antibody to immunoglobulin E. Guidelines for the treatment of chronic idiopathic urticaria (also known as chronic spontaneous urticaria) recommend the use of omalizumab as third-line therapy in addition to high doses of histamine receptor type 1 (H 1 ) antihistamines when they are unsuccessful as first- and second-line therapy. We performed a systematic review of the literature to identify studies that evaluated the efficacy of omalizumab for the treatment of chronic idiopathic urticaria, in both controlled and real-world settings, to assess its potential role as a preferred therapy. The PubMed, ScienceDirect, LILACS (Latin American and Caribbean Health Sciences Literature), and Google Scholar databases were searched between January 1, 2000, and November 21, 2016. The search was limited to articles published in peer-reviewed journals in the English language, and 29 studies were included in this review. Omalizumab 300 mg administered every 4 weeks appears to be the most effective and safe dosage, with a rapid response time, for the treatment of chronic idiopathic urticaria, with few minor adverse effects, and appears to be safe in the offspring of pregnant patients who received the drug. However, as published studies of omalizumab are sparse, future studies are warranted. When findings are confirmed in larger studies, due to its efficacy, safety, and increased benefit/cost ratio, omalizumab could become the preferred method of treatment for chronic idiopathic urticaria in patients unresponsive to H 1 antihistamines. © 2017 Pharmacotherapy Publications, Inc.

Clemens, Pamela L; Cloyd, James C; Kriel, Robert L; Remmel, Rory P

2007-01-01

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

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.

National Systematic Legal Review of State Policies on Emergency Medical Services Licensure Levels' Authority to Administer Opioid Antagonists.

Science.gov (United States)

Kinsman, Jeremiah M; Robinson, Kathy

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

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.

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

Directory of Open Access Journals (Sweden)

Juliane Bremer

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

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

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

Brentnall, C; Cheng, Z; McKellar, Q A; Lees, P

2012-09-15

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

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

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 (Pdetomidine from 10 to 20 µg/kg increased the degree of sedation when administered with the same dose of buprenorphine (7.5 µg/kg). When administered with 20 µg/kg detomidine, increasing the dose of buprenorphine from 7.5 to 10 µg/kg did not influence the degree of sedation achieved.

There is broad consensus that good outcome measures are needed to distinguish interventions that are effective from those that are not. This task requires standardized, patient-centered measures that can be administered at a low cost. We developed a questionnaire to assess short- and long......-term patient-relevant outcomes following knee injury, based on the WOMAC Osteoarthritis Index, a literature review, an expert panel, and a pilot study.

Glatz, T.; Ikegami, M.; Jobe, A.

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.

2015-07-01

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

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.)

2011-01-01

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

Pavlovian conditioning between co-administered drugs: elicitation of an apomorphine-induced antiparkinsonian response by scopolamine.

Science.gov (United States)

Carey, R J

1991-01-01

Sprague-Dawley rats with unilateral 6-OHDA substantia nigra lesions were given combined scopolamine (0.5 mg/kg IP) and apomorphine (0.05 mg/kg SC) treatments. In this animal model, scopolamine, when administered separately, induces ipsilateral rotation and apomorphine, contralateral rotation. When these drugs are co-administered at 0.5 mg/kg and 0.05 mg/kg dose levels, respectively, animals rotate in the contralateral direction, creating the opportunity for the stimulus effect of scopolamine to become associated with the response effect of apomorphine. In tests with scopolamine (0.5 mg/kg), animals that previously had scopolamine and apomorphine co-administered rotated contralaterally in the test chamber, thereby behaving as if they had received apomorphine. Thus, scopolamine exhibited a functionally acquired conditioned stimulus (CS) property by eliciting the apomorphine response of contralateral rotation as a conditioned response. This acquired CS property was extinguished with separate scopolamine trials and reacquired following one scopolamine-apomorphine co-administration trial.

BACKGROUND: Antihistamines (H1-receptor antagonists) act by competitive antagonism of histamine at H1-receptors. In addition, high concentrations of some antihistamines inhibit allergen-induced histamine release from mast cells in vitro. OBJECTIVE: The purpose of this study was to determine...... the effect of intranasal azelastine or systemic cetirizine (both potent antihistamines) on the allergen-induced release of mast-cell mediators from the human nasal mucosa in vivo. METHODS: Patients allergic to birch pollen (n = 11) and control subjects not allergic to birch pollen (n = 5) were included......, nasal allergen challenges were performed, and the number of sneezes were counted. In addition, nasal lavage fluid was collected, and the levels of mast-cell mediators (histamine and tryptase) were measured. RESULTS: The allergen challenge of patients allergic to pollen produced sneezing...

Fishback, Joanna E; Stronsky, Sabrina M; Green, Catherine A; Bean, Krystal D; Froude, Jeffrey W

2016-02-01

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

Nasally-Administered Oxytocin Has Limited Effects on Owner-Directed Attachment Behavior in Pet Dogs (Canis lupus familiaris

Directory of Open Access Journals (Sweden)

Lauren E. Thielke

2017-09-01

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.

The chromosomally abnormal clones occurring with high frequencies in bone marrow of 3 Thorotrast administered patients were studied by annual follow up observations. In one case the frequency of the clone was maintained fairly constant, but in another case it showed a tendency of increase, and in still another case the frequency of the clone showed drastic changes from year to year. The karyotypes of the clones showed remarkable chromosome abnormalities, among which the large partial loss of chromosomes was especially noted in all the 3 cases. (author)

1983-01-01

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

Pair housing differentially affects motivation to self-administer cocaine in male and female rats.

Westenbroek, Christel; Perry, Adam N; Becker, Jill B

2013-09-01

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.

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.

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.

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

Haematological disorders in Thorotrast-administered patients in Japan

International Nuclear Information System (INIS)

Kamiyama, Ryuichi; Hatakeyama, Shigeru

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.

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.

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)

Hayward, Kathryn S; Neibling, Bridee A; Barker, Ruth N

2015-01-01

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.

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

Antihistamines have been classifed as first or second generation drugs, according to their pharmacokinetic properties, chemical structure and adverse effects. The adverse effects of antihistamines upon the central nervous system (CNS) depend upon their capacity to cross the blood-brain barrier (BBB) and bind to the central H1 receptors (RH1). This in turn depends on the lipophilicity of the drug molecule, its molecular weight (MW), and affinity for P-glycoprotein (P-gp) (CNS xenobiotic substances extractor protein). First generation antihistamines show scant affinity for P-gp, unlike the second generation molecules which are regarded as P-gp substrates. Histamine in the brain is implicated in many functions (waking-sleep cycle, attention, memory and learning, and the regulation of appetite), with numerous and complex interactions with different types of receptors in different brain areas. Bilastine is a new H1 antihistamine that proves to be effective in treating allergic rhinoconjunctivitis (seasonal and perennial) and urticaria. The imaging studies made, as well as the objective psychomotor tests and subjective assessment of drowsiness, indicate the absence of bilastine action upon the CNS. This fact, and the lack of interaction with benzodiazepines and alcohol, define bilastine as a clinically promising drug with a good safety profile as regards adverse effects upon the CNS.

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.

Fexofenadine Suppresses Delayed-Type Hypersensitivity in the Murine Model of Palladium Allergy

Directory of Open Access Journals (Sweden)

Ryota Matsubara

2017-06-01

Full Text Available Palladium is frequently used in dental materials, and sometimes causes metal allergy. It has been suggested that the immune response by palladium-specific T cells may be responsible for the pathogenesis of delayed-type hypersensitivity in study of palladium allergic model mice. In the clinical setting, glucocorticoids and antihistamine drugs are commonly used for treatment of contact dermatitis. However, the precise mechanism of immune suppression in palladium allergy remains unknown. We investigated inhibition of the immune response in palladium allergic mice by administration of prednisolone as a glucocorticoid and fexofenadine hydrochloride as an antihistamine. Compared with glucocorticoids, fexofenadine hydrochloride significantly suppressed the number of T cells by interfering with the development of antigen-presenting cells from the sensitization phase. Our results suggest that antihistamine has a beneficial effect on the treatment of palladium allergy compared to glucocorticoids.

Pancreatic extracorporeal shock wave lithotripsy (P-ESWL) is the first-line therapy for large pancreatic duct stones. Although it is a highly effective and safe procedure for the fragmentation of pancreatic stones, it is still not complication-free. Just like endoscopic retrograde cholangiopancreatography (ERCP), pancreatitis is the most common complication. To date, nonsteroidal anti-inflammatory drugs (NSAIDs) have proven to be the only effective prophylactic medication for post-ERCP pancreatitis and the European, American and Japanese Society for Gastrointestinal Endoscopy guidelines have recommended prophylactic rectally administered indomethacin for all patients undergoing ERCP. Given the little research about effective prevention for post P-ESWL pancreatitis, we aim to determine whether rectally administered indomethacin can reduce post-ESWL-pancreatitis. The RIPEP study is a prospective, randomized, double-blinded, placebo-controlled trial. One thousand three hundred and seventy patients with chronic pancreatitis and pancreatic stones (>5 mm in diameter) treated with P-ESWL at Changhai Hospital will be randomly allocated to rectally administered indomethacin or placebo therapy before the procedure. The primary endpoint is the incidence of post-ESWL pancreatitis. Secondary endpoints include the severity of pancreatitis, occurrence rate of asymptomatic hyperamylasemia and other complications. The RIPEP trial is designed to show that rectally administered indomethacin reduces the development and severity of post-ESWL pancreatitis and benefits patients treated with P-ESWL.

To investigate the sedative effects in dogs of tiletamine-zolazepam-acepromazine (TZA) or ketamine-flunitrazepam (KF) administered orally and to evaluate the effectiveness of encapsulated TZA for capturing free-roaming dogs. Experimental study followed by a field trial. Six research dogs and 27 free-roaming dogs. In a pilot study, six research dogs were administered liquid TZA (20 mg kg -1 tiletamine-zolazepam and 2 mg kg -1 acepromazine) or liquid KF (50 mg kg -1 ketamine and 2 mg kg -1 flunitrazepam) orally: treatment 1, forcefully squirting liquid medication into the mouth; treatment 2, encapsulating liquid medication for administration in canned food; treatment 3, administering liquid medication mixed with gravy. Sedation was scored. A follow-up field trial attempted capture of 27 free-roaming dogs. In the pilot study, the median time (range) to lateral recumbency (% dogs) after TZA administration was: treatment 1, 47.5 (35-80) minutes (67%); treatment 2, 30 (15-65) minutes (83%); and treatment 3, 75 (45-110) minutes (100%). No dogs in KF treatment 2 or 3 achieved lateral recumbency. Based on these results, 20 free-roaming dogs were offered encapsulated TZA in canned food: TZ (20 mg kg -1 ) and acepromazine (2 mg kg -1 ). Of these, no further drugs to four dogs (one dog captured), 10 dogs were administered a second dose within 30 minutes (five dogs captured) and six dogs were administered TZ (5 mg kg -1 ) and xylazine (1.1-2.2 mg kg -1 ) intramuscularly by blow dart (six dogs captured). Seven dogs were initially offered twice the TZA dose (five dogs captured). In total, 63% free-roaming dogs were captured after administration of encapsulated TZA in canned food. Oral administration of encapsulated TZA in canned dog food can aid in the capture of free-roaming dogs, but additional drugs may be required. The sedation onset time and medication palatability influenced the capture rate. Copyright © 2017 Association of Veterinary Anaesthetists and

1998-04-01

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

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

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.

The Effect on Treatment Adherence of Administering Drugs as Fixed-Dose Combinations versus as Separate Pills: Systematic Review and Meta-Analysis.

Science.gov (United States)

van Galen, Katy A; Nellen, Jeannine F; Nieuwkerk, Pythia T

2014-01-01

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.

Challenges in Developing a Biochip for Intact Histamine Using Commercial Antibodies

Directory of Open Access Journals (Sweden)

Leena Mattsson

2017-12-01

Full Text Available This study describes the development and the challenges in the development of an on-chip immunoassay for histamine using commercially available antibodies. Histamine can be used as an indicator of food freshness and quality, but it is also a relevant marker in clinical diagnostics. Due to its low molecular weight, simple structure and thus low immunogenicity production of high specificity and affinity antibodies is difficult. From six commercial anti-histamine antibodies tested, only two bound the histamine free in the solution. A fluorescent on-chip immunoassay for histamine was established with a dynamic range of 8–111 µg/mL using polyclonal anti-histamine antibody H7403 from Sigma (Mendota Heights, MN, USA. The anti-histamine antibodies described and used in published literature are thoroughly reviewed and the quality of commercial antibodies and their traceability and quality issues are highlighted and extensively discussed.

Supraspinally-administered agmatine attenuates the development of oral fentanyl self-administration

Science.gov (United States)

Wade, Carrie L.; Schuster, Daniel J.; Domingo, Kristine M.; Kitto, Kelley F.; Fairbanks, Carolyn A.

2009-01-01

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

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

Recently, new evidence-based recommendations have been introduced for diagnosing and managing otitis media with effusion (OME) in children. However, there are some difficulties to follow the general guidelines in the tertiary hospitals. The purpose is to evaluate the efficiency of antibiotics or antihistamines for treatment of children with OME in the tertiary hospital with a randomized prospective clinical study. Eighty-four children with OME who had been diagnosed in the tertiary hospital were randomized to receive 5 different medications for 2 weeks. We prescribed antibiotics (amoxicillin-clavulanate syrup) in Group I (n=16), antibiotics/steroids (prednisolone) in Group II (n=18), antibiotics/antihistamines (ebastine) in Group III (n=15), antibiotics/steroids/antihistamines in Group IV (n=17), and mucolytics (ivy leaf extract) in Group V (n=17) for control. We followed-up children every 2 weeks and evaluated the state of OME at 3 months. Thirty six (42.9%) of 84 children were resolved within average 6.9 weeks after the treatments. Thirty-six (42.9%) were treated with ventilation tube insertion and 12 patients (14.3%) were observed. There was no difference in the resolution rates of OME among the five different protocols (P>0.05). There was no difference in the resolution rates among groups who used steroids, antihistamines, steroids and antihistamines, or other medications to manage 42 children with allergies (P>0.05). In the tertiary hospital, the cure rate of children with OME was not as high as well-known, and antibiotics or anti-allergic medications were not more effective than control. We may, therefore, need any other guidelines which are different from the previous evidence-based recommendations, including early operation in the tertiary hospitals.

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

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.

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

Rupprecht, Laura E; Smith, Tracy T; Donny, Eric C; Sved, Alan F

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.

Iatrogenic nocturnal eneuresis- an overlooked side effect of anti histamines?

Directory of Open Access Journals (Sweden)

D Italiano

2015-01-01

Full Text Available Nocturnal enuresis is a common disorder in childhood, but its pathophysiological mechanisms have not been fully elucidated. Iatrogenic nocturnal enuresis has been described following treatment with several psychotropic medications. Herein, we describe a 6-year-old child who experienced nocturnal enuresis during treatment with the antihistamine cetirizine. Drug rechallenge was positive. Several neurotransmitters are implicated in the pathogenesis of nocturnal enuresis, including noradrenaline, serotonin and dopamine. Antihistamine treatment may provoke functional imbalance of these pathways resulting in incontinence.

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

PHARMACOKINETICS OF SINGLE-DOSE ORALLY ADMINISTERED CIPROFLOXACIN IN CALIFORNIA SEA LIONS (ZALOPHUS CALIFORNIANUS).

Barbosa, Lorraine; Johnson, Shawn P; Papich, Mark G; Gulland, Frances

2015-06-01

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

2004-01-01

Full Text Available Subcutaneous emphysema is a rare complication in dentistry, which may lead to diagnostic errors and inadequate therapy. A 17 years old female patient, in whom the separation of tooth roots was performed by the use of air-powered drill during the extraction of the first right lower molar, is presented in this paper. During the intervention, swelling of the right half of the face and the lower eyelid suddenly occurred, accompanied with simultaneous feeling of choking, and pressure in the neck and chest. Because of the suspicion of the allergic reaction, the patient was administered antihistaminic agent, together with parenteral corticosteroid, and was sent to an institution where she was treated as an in-patient. During hospitalization, subcutaneous emphysema of the face and neck was diagnosed by physical and x-ray examination. The emphysema completely disappeared after the use of oxygen and antibiotics.

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

2009-12-01

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

2017-01-01

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.

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

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

2014-06-01

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

Interviewer versus self-administered health-related quality of life questionnaires - Does it matter?

2011-05-01

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

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...

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.)

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

Full Text Available 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.

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

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 .

Nonprescription medications for respiratory symptoms: Facts and marketing fictions.

Science.gov (United States)

Weinberger, Miles; Hendeles, Leslie

2018-05-01

There are many nonprescription (over-the-counter [OTC]) medications available on pharmacy shelves marketed for relief of respiratory symptoms. The number of such medications has been increasing. This review provides an evidence-based examination of OTC products used for respiratory symptoms. Antihistamines, decongestants, mucolytics, antitussives, and intranasal steroids were selected as the most common OTC medications taken by adults and children for various respiratory symptoms. Controlled clinical trials of efficacy were identified by searching a medical literature data base. Those trials and key publications related to the pharmacokinetics and pharmacodynamics of the products were reviewed. Comparisons of the various OTC antihistamines' ability to suppress the effects of histamine were related to their clinical benefit. Intranasal corticosteroids are the preferred agents for maintenance therapy of persistent nasal congestion and are highly effective for symptoms of inhalant allergy other than allergic conjunctivitis. The disconnect between marketing claims and evidence was demonstrated for antihistamines and oral alpha-1 adrenergic agonist decongestants. Data for OTC mucolytics and antitussives were insufficient to justify their use based on the evidence. There was little relationship between marketing claims and evidence regarding OTC medications used for respiratory symptoms. Analysis of data supported cetirizine, levocetirizine, and fexofenadine as the most effective of the OTC antihistamines. There were no data that supported the use of oral phenylephrine as a decongestant. Neither OTC mucolytics or antitussives provided sufficient evidence to justify their use.

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

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

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.

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 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.

2013-01-01

We conducted randomized clinical trials to examine the impact of direct-to-consumer advertisements on the efficacy of a branded drug. We compared the objectively measured, physiological effect of Claritin (Merck & Co.), a leading antihistamine medication, across subjects randomized to watch a movie spliced with advertisements for Claritin or advertisements for Zyrtec (McNeil), a competitor antihistamine. Among subjects who test negative for common allergies, exposure to Claritin advertisements rather than Zyrtec advertisements increases the efficacy of Claritin. We conclude that branded drugs can interact with exposure to television advertisements. PMID:23878212

Effect of administered radioactive dose level on image quality of brain perfusion imaging with 99mTc-HMPAO

2008-01-01

Full Text Available Brain perfusion imaging by means of 99mTc-labeled hexamethyl propylene amine oxime (HMPAO is a well-established Nuclear Medicine diagnostic procedure. The administered dose range recommended by the supplying company and reported in bibliography is rather wide (approximately 9.5-27 mCi. This fact necessitates further quantitative analysis of the technique, so as to minimise patient absorbed dose without compromising the examination diagnostic value. In this study, a quantitative evaluation of the radiopharmaceutical performance for different values of administered dose (10, 15, 20 mCi was carried out. Subsequently, a generic image quality index was correlated with the administered dose, to produce an overall performance indicator. Through this cost-to-benefit type analysis, the necessity of administration of higher radioactive dose levels in order to perform the specific diagnostic procedure was examined.Materials & methods: The study was based on a sample of 78 patients (56 administered with 10 mCi, 10 with 15 mCi and 12 with 20 mCi. Some patients were classified as normal, while others presented various forms of pathology. Evaluation of image quality was based on contrast, noise and contrast-to-noise ratio indicators, denoted CI, NI and CNR respectively. Calculation of all indicators was based on wavelet transform. An overall performance indicator (denoted PI, produced by the ratio of CNR by administered dose, was also calculated.Results: Calculation of skewness parameter revealed the normality of CI, NI and non-normality of CNR, PI populations. Application of appropriate statistical tests (analysis of variance for normal and Kruskal-Wallis test for non-normal populations showed that there is a statistically significant difference in CI (p0.05 values. Application of Tukey test for normal populations CI, NI led to the conclusion that CI(10 mCi = CI(20 mCiNI(20 mCi, while NI(15 mCi can not be characterised. Finally, application of non

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

LENUS (Irish Health Repository)

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

Radiation exposure to nuclear medicine technologists from administering I-131 therapy dosages

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

Orally administered nicotine induces urothelial hyperplasia in rats and mice

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

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

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

Ten to thirty percent of lung cancer is thought to be of occupational origin. Lung cancer is under-declared as an occupational disease in Europe, and most declarations of occupational disease concern asbestos. The purpose of this study was to design and validate a short, sensitive self-administered questionnaire, as an aid for physicians in detecting occupational exposure to asbestos and other lung carcinogens in order to remedy occupational lung cancer under-declaration. Cross-sectional study. A short (30-question) self-administered questionnaire was drawn up by oncologist-pneumologists and occupational physicians, covering situations of exposure to proven and probable lung carcinogens. Understanding and acceptability were assessed on 15 lung cancer patients. Validity and reliability were assessed on 70 lung cancer patients by comparison against a semi-directive questionnaire considered as gold standard. Sensitivity and specificity were assessed by comparing responses to items on the two questionnaires. Reliability was assessed by analysing the kappa concordance coefficient for items on the two questionnaires. Sensitivity was 0.85 and specificity 0.875. Concordance between responses on the two questionnaires was 85.7%, with a kappa coefficient of 0.695 [0.52-0.87]. Mean self-administration time was 3.1 min (versus 8.12 min to administer the gold-standard questionnaire). In 16 patients, the self-administered questionnaire detected lung carcinogen exposure meeting the criteria for occupational disease. The present short, easy-to-use self-administered questionnaire should facilitate detection of occupational exposure to lung carcinogens. It could be used in occupational lung cancer screening and increase the presently low rate of application for recognition of lung cancer as an occupational disease.

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.

2017-03-01

Full Text Available Taste of a pharmaceutical formulation is an important parameter for the effectiveness of pharmacotherapy. Cetirizine dihydrochloride (CET is a second-generation antihistamine that is commonly administered in allergy treatment. CET is characterized by extremely bitter taste and it is a great challenge to successfully mask its taste; therefore the goal of this work was to formulate and characterize the microparticles obtained by the spray drying method with CET and poly(butyl methacrylate-co-(2-dimethylaminoethyl methacrylate-co-methyl methacrylate 1:2:1 copolymer (Eudragit E PO as a barrier coating. Assessment of taste masking by the electronic tongue has revealed that designed formulations created an effective taste masking barrier. Taste masking effect was also confirmed by the in vivo model and the in vitro release profile of CET. Obtained data have shown that microparticles with a drug/polymer ratio (0.5:1 are promising CET carriers with efficient taste masking potential and might be further used in designing orodispersible dosage forms with CET.

Cetirizine is an antihistamine used in performance horses for the treatment of hypersensitivity reactions and as such a withdrawal time is necessary prior to competition. The objective of the current study was to describe the disposition and elimination of cetirizine following oral administration in order to provide additional serum concentration data upon which appropriate regulatory recommendations can be established. Nine exercised thoroughbred horses were administered 0.4 mg/kg of cetirizine orally BID for a total of five doses. Blood samples were collected immediately prior to drug administration and at various times postadministration. Serum cetirizine concentrations were determined and selected pharmacokinetic parameters determined. The serum elimination half-life was 5.83 ± 0.841 h. Average serum cetirizine concentrations were still above the LOQ of the assay (0.05 ng/mL) at 48 h (final sample collected) postadministration of the final dose. © 2016 John Wiley & Sons Ltd.

Omalizumab for treating chronic spontaneous urticaria: an expert review on efficacy and safety.

Science.gov (United States)

Giménez-Arnau, Ana M

2017-03-01

Chronic spontaneous urticaria (CSU) is characterized by the recurrence of itchy hives and/or angioedema for greater than six weeks, with no known external trigger. Omalizumab, a humanized, recombinant, monoclonal anti-IgE antibody, is the only approved add-on therapy for H1-antihistamine refractory CSU patients. Areas covered: The objective of this article is to discuss the mechanism of action, pharmacokinetics and pharmacodynamics of omalizumab for the treatment of CSU. The review also summarizes efficacy and safety data from proof-of-concept, phase II (X-CUISITE, MYSTIQUE), and pivotal phase III omalizumab studies (ASTERIA I, ASTERIA II, and GLACIAL). Expert opinion: Omalizumab is a clinically effective and safe biological therapy for treating H1-antihistamine refractory CSU patients. It significantly reduces CSU symptoms (hives, itch and angioedema), and improves patient health-related quality of life. While omalizumab is already integral to the treatment of antihistamine refractory CSU, widespread use will depend on legal and economic factors, as well as improvements in the early and accurate diagnosis of CSU patients who would benefit from treatment.

[Management of side effects of targeted therapies in renal cancer: iatrogenic side effects].

Massard, Christophe; Patard, Jean-Jacques; Hermine, Olivier; Ravaud, Alain

2011-01-01

Since premedication of patients with an H1 antihistamine is recommended before the start of the intravenous infusion of temsirolimus, temsirolimus is to be used with caution in cases where there is a history of hypersensitivity to this class of antihistamines, or medical contra-indication for treatment with antihistamines. Comorbidities and co-medications must be taken into account in the prescription of targeted therapies. For sunitinib, sorafenib, and pazopanib: potential drug interactions are possible with inducers/inhibitors of CYP3A4, anti-hypertensive drugs, antidiabetic drugs, thyroid hormones, and anticoagulant treatments. The combination of bevacizumab and sunitinib is very toxic (microangiopathic haemolytic anaemia), and is contra-indicated unless part of a clinical trial. Screening, equilibration or treatment of hypothyroidism, anaemia, undernutrition, hypophosphatemia, hypomagnesaemia, sleep disorders, depression or other comorbidities, which may contribute to asthenia is recommended. In patients treated with sunitinib or pazopanib, a thyroid function test is recommended at the treatment centre as well as regular TSH assays. Copyright © 2011 Société Française du Cancer.

2009-01-01

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

2001-11-16

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

Pharmacokinetic-pharmacodynamic integration and modelling of oxytetracycline administered alone and in combination with carprofen in calves.

2013-06-01

The pharmacokinetic (PK) and pharmacodynamic (PD) profiles of oxytetracycline were investigated, when administered both alone and in the presence of carprofen, in healthy calves. The study comprised a four treatment, four sequences, and four period cross-over design and used a tissue cage model, which permitted the collection of serum, inflamed tissue cage fluid (exudate) and non-inflamed tissue cage fluid (transudate). There were no clinically relevant differences in the PK profile of oxytetracycline when administered alone and when administered with carprofen. PK-PD integration was undertaken for a pathogenic strain of Mannheimia haemolytic (A1 76/1), by correlating in vitro minimum inhibitory concentration (MIC) and time-kill data with in vivo PK data obtained in the cross-over study. Based on in vitro susceptibility in cation adjusted Mueller Hinton Broth (CAMHB) and in vivo determined PK variables, ratios of maximum concentration (Cmax) and area under curve (AUC) to MIC and time for which concentration exceeded MIC (T>MIC) were determined. The CAMHB MIC data satisfied integrated PK/PD relationships predicted to achieve efficacy for approximately 48 h after dosing; mean values for serum were 5.13 (Cmax/MIC), 49.3 h (T>MIC) and 126.6 h (AUC(96h)/MIC). Similar findings were obtained when oxytetracycline was administered in the presence of carprofen, with PK-PD indices based on MIC determined in CAMHB. However, PK-PD integration of data, based on oxytetracycline MICs determined in the biological fluids, serum, exudate and transudate, suggest that it possesses, at most, limited direct killing activity against the M. haemolytica strain A1 76/1; mean values for serum were 0.277 (Cmax/MIC), 0 h (T>MIC) and 6.84 h (AUC(96h)/MIC). The data suggest that the beneficial therapeutic effects of oxytetracycline may depend, at least in part, on actions other than direct inhibition of bacterial growth. Copyright © 2013 Elsevier Ltd.

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

Full Text Available 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.

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

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

Allergic rhinitis is usually treated with oral antihistamines or nasal steroids. Topically active nasal antihistamine is a new treatment modality for allergic rhinitis. The efficacy in comparison to well established topical treatment alternatives is not fully known. To compare the efficacy of intranasally administered azelastine to budesonide, at their respectively recommended dosage, on the symptoms of perennial rhinitis patients. A placebo-controlled, randomized, parallel group study was conducted to compare the efficacy and tolerability of intranasal budesonide aqueous suspension (256 microg once daily) with azelastine hydrochloride nasal spray (280 microg twice daily (560 microg/day)) and with placebo in the treatment of perennial allergic rhinitis. The 195 patients (with at least a 2-year history of perennial allergic rhinitis) recorded individual nasal symptom scores, the degree of symptom control achieved and any adverse events experienced over a 2-week baseline period and a 6-week treatment period. Following treatment, the reductions in mean combined and individual nasal symptom scores from baseline values were significantly greater in the budesonide group compared with the placebo group (P < .0001 for all variables except runny nose P = .01). In patients treated with budesonide, there were also significantly larger reductions from baseline values in combined nasal symptom scores (P < .01) and in scores for all individual nasal symptoms (P < or = .05) compared with those treated with azelastine. The reductions from baseline in both combined and individual nasal symptom scores did not differ between azelastine and placebo. The study medications were well tolerated, producing no unexpected or serious treatment-related adverse events. A once-daily dose of 256 microg of intranasal budesonide aqueous suspension is significantly more effective at relieving the symptoms of perennial allergic rhinitis compared with a twice daily dose of 280 microg of azelastine

Adenoids, tubal tonsil, palatine tonsil, and lingual tonsil are immunological organs included in the Waldeyer's ring, the basic function of which is the antibody production to common environmental antigens. Adenoidal hypertrophy (AH) is a major medical issue in children, and adenoidectomy is still the most used treatment worldwide. The response of adenoids to allergens is a good model to evaluate their immunological function. This report assessed the immunological changes in adenoid tissues from children with allergic rhinitis (AR) undergoing sublingual immunotherapy (SLIT). Adenoid samples from 16 children (seven males, nine females, mean age 7.12 years) with AH and clinical indication to adenoidectomy were collected. Of them, five children were not allergic and 11 had house dust mite and grass pollen-induced AR. Among allergic children, in four AR was treated by antihistamines while in seven AR was treated by high-dose SLIT during 4-6 months. The evaluation addressed the T helper 1 (Th1), Th2, and Th3 cells by performing a PCR array on mRNA extracted from adenoid samples. In non-allergic children, a typical Th1 pattern was found. SLIT induced a strong down-regulation of genes involved in Th2 and Th1 activation and function. In particular, in SLIT-treated allergic children IL-4, CCR2, CCR3, and PTGDR2 (Th2 related genes) and CD28, IL-2, and INHA (Th1 related genes) expression was reduced, compared with children treated with antihistamines. These preliminary findings warrant investigation in trials including larger numbers of patients, but indicate that hypertrophic adenoids of allergic children have the typical response to the specific allergen administered by SLIT. This should suggest that one should reconsider the immunological role of adenoids.

Mequitazine is a so-called 'non-sedative' second-generation antihistamine even though it has never been firmly established that this drug's sedative potential actually differs from that of the 'sedative' first-generation antihistamines. The present study compares the sedative effects of three doses of mequitazine on actual driving, psychomotor performance and memory with those of a first- and a second-generation antihistamine. Eighteen healthy volunteers received on separate days a single dose of 5, 10 and 15 mg mequitazine, 10 mg cetirizine, 6 mg dexchlorpheniramine and placebo. Drug effects were assessed using two actual driving tests (highway-driving test and car-following test), cognitive and psychometric tests (tracking, divided attention, memory, reasoning and critical flicker fusion), pupil size and questionnaires. Highway-driving data revealed an overall effect of Treatment on the standard deviation of lateral position (SDLP). Dexchlorpheniramine impaired driving performance as indicated by a significant rise in SDLP. Mequitazine significantly increased SDLP in a dose-related manner, but the separate dose effects failed to reach statistical significance. Divided attention performance was also affected by Treatment. Reaction time (RT) during mequitazine treatments increased in a dose-related manner and significantly differed from placebo at the highest dose. Subjects reported to be less alert after treatment with dexchlorpheniramine. Cetirizine did not affect performance in any of the tasks. It was concluded that mequitazine is mildly sedating. The effects of mequitazine are comparable to those of other second-generation antihistamines, in that it causes mild driving impairment, particularly at higher doses.

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.

2014-08-01

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

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

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

Full Text Available Abstract 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

While stimulation of the peripheral nerves increases the pain threshold, chronic pressure stimulation of the sciatic nerve is associated with sciatica. We recently found that acute pressure block of the sciatic nerve inhibits pain. Therefore, we propose that, the pain pathology-causing pressure is chronic, not acute. Here, we report a novel self-administered method: acute pressure block of the sciatic nerves is applied by the patients themselves for short-term relief of pain from dental diseases. This was a randomized, single-blind study. Hospital patients. Patients aged 16-60 years with acute pulpitis, acute apical periodontitis, or pericoronitis of the third molar of the mandible experiencing pain ≥3 on the 11-point numerical pain rating scale. Three-minute pressure to sciatic nerves was applied by using the hands (hand pressure method) or by having the patients squat to force the thigh and shin as tightly as possible on the sandwiched sciatic nerve bundles (self-administered method). The primary efficacy variable was the mean difference in pain scores from the baseline. One hundred seventy-two dental patients were randomized. The self-administered method produced significant relief from pain associated with dental diseases (P ≤ 0.001). The analgesic effect of the self-administered method was similar to that of the hand pressure method. The self-administered method is easy to learn and can be applied at any time for pain relief. We believe that patients will benefit from this method. © 2014 The Authors. Pain Medicine published by Wiley Periodicals, Inc. on behalf of American Academy of Pain Medicine.

Clinician-administered measures to assess severity of illness anxiety and response to treatment are few. The authors evaluated a modified version of the hypochondriasis-Y-BOCS (H-YBOCS-M), a 19-item, semistructured, clinician-administered instrument designed to rate severity of illness-related thoughts, behaviors, and avoidance. The scale was administered to 195 treatment-seeking adults with DSM-IV hypochondriasis. Test-retest reliability was assessed in a subsample of 20 patients. Interrater reliability was assessed by 27 interviews independently rated by four raters. Sensitivity to change was evaluated in a subsample of 149 patients. Convergent and discriminant validity was examined by comparing H-YBOCS-M scores to other measures administered. Item clustering was examined with confirmatory and exploratory factor analyses. The H-YBOCS-M demonstrated good internal consistency, interrater and test-retest reliability, and sensitivity to symptom change with treatment. Construct validity was supported by significant higher correlations with scores on other measures of hypochondriasis than with nonhypochondriacal measures. Improvement over time in response to treatment correlated with improvement both on measures of hypochondriasis and on measures of somatization, depression, anxiety, and functional status. Confirmatory factor analysis did not show adequate fit for a three-factor model. Exploratory factor analysis revealed a five-factor solution with the first two factors consistent with the separation of the H-YBOCS-M items into the subscales of illness-related avoidance and compulsions. H-YBOCS-M appears to be valid, reliable, and appropriate as an outcome measure for treatment studies of illness anxiety. Study results highlight "avoidance" as a key feature of illness anxiety-with potentially important nosologic and treatment implications. © 2012 Wiley Periodicals, Inc.

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

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

Full Text Available Poslednjih godina beleži se kontinuirani rast prevalencije alergijskih oboljenja. Alergijski imunski odgovor predstavlja jednu kompleksnu mrežu ćelijskih događaja u kojoj učestvuju mnogobrojne imunske ćelije i medijatori. On predstavlja interakciju urođenog i stečenog imunskog odgovora. Ključnu ulogu u imunološkoj kaskadi zauzima histamin, prirodni sastojak tela, koga u alergijskom inflamatornom odgovoru oslobađaju mastociti i bazofili. Cilj ovog rada bio je naglasiti ulogu histamina u alergijskim imunološkim događajima, njegov efekat na Th1 i Th2 subpopulaciju limfocita i produkciju odgovarajućih citokina, kao i ulogu blokatora histamina u tretmanu ovih stanja. Histamin ostvaruje svoj efekat vezivanjem za četiri tipa svojih receptora koji su široko distribuirani u organizmu. Blokatori histamina blokiraju mnogobrojne efekte histamina vezivanjem za ove receptore. Cetirizin, visoko selektivni antihistaminik druge generacije, ne ostvaruje svoje efekte samo vezivanjem za H1 receptore već dovodi do atenuisanja mnogobrojnih zbivanja tokom inflamacijskog procesa. Dobro poznavanje efekata histaminskih blokatora, među njima i cetirizina, može dovesti do pravog odabira terapije u tretmanu alergijskih oboljenja.

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

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

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

Full Text Available Female-controlled contraception/HIV prevention is critical to address health issues associated with gender inequality. Therefore, a contraceptive which can be administered in tandem with a microbicide to inhibit sexually transmitted infections, is desirable. Uterine leukemia inhibitory factor (LIF is obligatory for blastocyst implantation in mice and associated with infertility in women. We aimed to determine whether a PEGylated LIF inhibitor (PEGLA was an effective contraceptive following vaginal delivery and to identify non-uterine targets of PEGLA in mice.Vaginally-applied (125I-PEGLA accumulated in blood more slowly (30 min vs 10 min and showed reduced tissue and blood retention (24 h vs 96 h compared to intraperitoneal injection in mice. Vaginally-applied PEGLA blocked implantation. PEGLA administered by intraperitoneal injection inhibited bone remodelling whereas vaginally-applied PEGLA had no effect on bone. Further, PEGLA had no effect in an animal model of multiple sclerosis, experimental auto-immune encephalomyelitis, suggesting PEGLA cannot target the central nervous system.Vaginally-administered PEGLA is a promising non-hormonal contraceptive, one which could be delivered alone, or in tandem with a microbicide. Vaginal application reduced the total dose of PEGLA required to block implantation and eliminated the systemic effect on bone, showing the vagina is a promising site of administration for larger drugs which target organs within the reproductive tract.

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)

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

Nanoparticles have been extensively developed for therapeutic and diagnostic applications. While the focus of nanoparticle trafficking in vivo has traditionally been on drug delivery and organ-level biodistribution and clearance, recent work in cancer biology and infectious disease suggests that targeting different cells within a given organ can substantially affect the quality of the immunological response. Here, we examine the cell-level biodistribution kinetics after administering ultrasma...

Doses of radioiodine administered for hyperthyroidism: a sampling of Belgian nuclear medicine physician's attitudes

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

The goal of this investigation was to assess the impact of the publication of the 2010 North American guidelines on the practice of nuclear medicine in children at 13 dedicated pediatric institutions within the United States and Canada by comparing results of similar surveys from 2007 and 2013. In 2013, a follow-up survey was performed of the original 13 dedicated pediatric institutions initially surveyed in 2007. Both surveys inquired about the administered activities for 16 nuclear medicine procedures commonly performed on children. The administered activity per body mass, the maximum activity, and the minimum activity for patients for each procedure were requested from each site. For each parameter the minimum and maximum reported values, as well as the median and the mean, were tabulated. The mean difference in the mean between 2007 and 2013 was calculated, as well as the 95% confidence intervals for the mean administered activity per body mass for both years. The factor of variation used with the previous survey for each parameter was calculated by taking the ratio of the maximum and minimum reported values. For the 8 procedures addressed in the 2010 North American guidelines, the percentage of institutions that were compliant (defined as within 20%) for each parameter were noted for both surveys. Institutions were asked whether they were familiar with "Image Gently," the North American guidelines, and the "Go with the Guidelines" campaign and whether they adjusted their administered activities on the basis of these guidelines. In general, the 13 pediatric institutions have reduced their administered activities in children, particularly for those procedures addressed by the 2010 North American guidelines. The average variability in the activity per body mass and the minimum activity as measured by the factor of variation were substantially reduced by 9.7% (from 3.1 to 2.8) and 24% (from 10.0 to 7.6). The average variability of the maximum activity was

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

2002-10-01

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

A 35-year-old man with end-stage kidney disease due to chronic glomerulonephritis was admitted to our hospital to start maintenance hemodialysis (HD). One hour after starting the first session of HD, he experienced general pruritus, urticaria, and dyspnea. Signs and symptoms were resolved by discontinuing HD and administrating an antihistamine drug; HD-associated anaphylactoid reactions were therefore suspected. Over the next few HD sessions, we changed the dialysis membrane, anticoagulant, HD circuit and needle, in that order, but general pruritus and urticaria again appeared within 3 h after starting each session of HD. Finally, when we changed the dialysate from acetate-containing bicarbonate dialysate to acetate-free bicarbonate dialysate, urticaria was clearly less than that seen in previous HD sessions, and subsided after discontinuation of HD. Subsequently, 20 mg of oral prednisolone (PSL) was administered 1 h before starting HD, and the patient did not experience general pruritus, urticaria, or dyspnea after starting the session. When administered acetate-containing bicarbonate dialysate after oral PSL pretreatment, the patient again experienced general pruritus, urticaria and dyspnea. Few reports have been published on the occurrence of anaphylactoid reactions during HD using acetate dialysate. We report a rare case of anaphylactoid reactions with acetate in acetate-containing bicarbonate dialysate that were reduced with the use of acetate-free bicarbonate dialysate and oral PSL pretreatment.

2001-01-01

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.

Alteration of intestinal microbiota in mice orally administered with salmon cartilage proteoglycan, a prophylactic agent.

Directory of Open Access Journals (Sweden)

Krisana Asano

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

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.

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

Skarda, R T; Muir, W W

1999-10-01

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

2016-09-01

Omalizumab has been recently approved for treating patients with refractory to H1- antihistamines chronic spontaneous urticaria (CSU). Although hair loss is listed among omalizumab side effects, there are no available data to estimate its frequency. We describe for the first time hair loss as a side effect associated with omalizumab administration in three women, 38, 62 and 70 years old, suffering from refractory to H1-antihistamines CSU. This information was retrieved from their Chronic Urticaria Quality of Life Questionnaires. Despite this side effect, all patients agreed to continue omalizumab regular administration. Hair loss appeared to be transient, lasting up to four months. All cases finally benefited from omalizumab continuation.

131I radiocapsules as a means of administering iodide to patients for diagnoses and/or therapy

International Nuclear Information System (INIS)

Pillay, M.; Li Jun; Berghout, A.; Cox, P.H.

1994-01-01

The use of radioiodide solution either for intravenous (sterile), or for oral use carries a risk of spillage and contamination (3). In addition, the amount of activity administered is seldom complete in terms of the absolute amount dispensed so that there always is 'left-over' activity in the syringe or beaker. This is particularly important when determining the 24 hour uptake of radioiodide in the thyroid. The use of encapsulated forms of iodide-131 excludes errors due to 'left-over' activity, and is certainly preferred from the radiation hygiene point of view. Radiocapsules are easy to administer and may even be used in uncooperative patients as described by Lowry et al (2). The widespread use of radiocapsules has been restricted because of concern about the speed of dissolution of the radiocapsules in the stomach (4). In this study we investigated the speed of the capsule disintegration in in-vitro, as well as in patients. (orig.) [de

Effect of administering a diet contamined with fumonisins on the kidneys of wistar rats

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

2006-09-01

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

Does the COPD assessment test (CAT(TM)) questionnaire produce similar results when self- or interviewer administered?

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.

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

Kearns, David N; Silberberg, Alan

2016-04-01

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

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

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

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.

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

The 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

2009-01-01

BACKGROUND: WHO recommends high-dose Vitamin A supplementation (VAS) at vaccination contacts after 6 months of age. It has not been studied whether the effect of VAS on mortality depends on the type of vaccine. We have hypothesized that VAS administered with measles vaccine (MV) is more beneficial...... than VAS with diphtheria-tetanus-pertussis (DTP) vaccine. We assessed the effect of VAS administered with different vaccines during national immunization days (NIDs). METHODS: In 2003, VAS was distributed during NIDs in Guinea-Bissau. Children 6 months or older were given VAS, and if they were missing...... vaccines, these were often given as well. We compared survival between children who had received VAS alone, VAS with DTP or DTP + MV, or VAS with MV. We also compared the survival between participants and non-participants. We followed 6- to 17-month old children until 18 months of age and analysed survival...

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.

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

Agmatine, an endogenous polyamine and putative neuromodulator, is known to have neuroprotective effects on various neurons in the central nervous system. We determined whether or not topically administered agmatine could reduce ischemic retinal injury. Transient ocular ischemia was achieved by intraluminal occlusion of the middle cerebral artery of ddY mice (30-35 g) for 2 h, which is known to also induce occlusion of the ophthalmic artery. In the agmatine group (N = 6), a 1.0 mM agmatine-containing ophthalmic solution was administered four times daily for 2 weeks before occlusion. In the control group (N = 6), a 0.1% hyaluronic acid ophthalmic solution was instilled at the same times. At 22 h after reperfusion, the eyeballs were enucleated and the retinal sections were stained by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL). Transient ocular ischemia induced apoptosis of retinal cells in the entire retinal layer, and topically administered agmatine can significantly reduce this ischemic retinal injury. The proportion of apoptotic cells was definitely decreased (P agmatine application effectively decreases retinal damage in an in vivo ocular ischemic injury model. This implies that agmatine is a good candidate as a direct neuroprotective agent for eyes with ocular ischemic diseases. PMID:22331138

To evaluate how well the medications currently approved in the United States for allergic rhinitis (AR) treat nasal symptoms when examined according to Food and Drug Administration-indicated uses and dosages. MEDLINE (1966 onward), EMBASE (1974 onward), and the Cochrane Library (2007) were systematically searched according to the following criteria defined at a roundtable meeting of the authors: randomized controlled trial, at least a 2-week duration, and approved indication and dosage in the United States. Data from studies that met the inclusion criteria were extracted into evidence tables, which were reviewed twice by the full panel of authors. Individual panel members also were asked to comment on abstracts, articles, and summary tables based on their known expertise. The entire faculty approved the selection of studies included in this review. Fifty-four randomized, placebo-controlled studies involving more than 14,000 adults and 1,580 children with AR met the criteria for review: 38 studies of seasonal allergic rhinitis (SAR; n = 11,980 adults and 946 children) and 12 studies of perennial allergic rhinitis (PAR; n = 3,800 adults and 366 children). The median percentage changes from baseline for total nasal symptom score for SAR were as follows: nasal antihistamines, -22.2%; oral antihistamines, -23.5%; intranasal steroids (INSs), -40.7%; and placebo, -15.0%. For PAR, the changes were as follows: oral antihistamines, -51.4%; INSs, -37.3%; and placebo, -24.8%. Data for mediator antagonists were limited. The data, although limited, confirm that INSs produce the greatest improvements in nasal symptoms in patients with SAR. In addition, INSs are effective for PAR, but the data were of variable quality, and oral antihistamines may be equally effective for some patients. The reporting of published data should be standardized to permit better comparisons in future studies.

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

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.

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.

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

International Nuclear Information System (INIS)

Schneider, S.; McGuire, S.A.

1994-05-01

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

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

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

No difference between the groups was found regarding...

Analysis of the population-level impact of co-administering ivermectin with albendazole or mebendazole for the control and elimination of Trichuris trichiura

Directory of Open Access Journals (Sweden)

Conclusions: Co-administering ivermectin notably increased the projected impact of preventive chemotherapy in high transmission settings and increased the feasibility for breaking transmission. This has important implications for control programmes, some of which may be shifting focus from morbidity control to interruption of transmission, and some of which may be logistically unable to provide preventive chemotherapy twice a year as recommended. However, the benefit of co-administering ivermectin is limited by the fact that 2–5 year olds are often ineligible to receive treatment.

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

Retinal protective effects of topically administered agmatine on ischemic ocular injury caused by transient occlusion of the ophthalmic artery

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

1980-03-01

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

Purpose Fixed-combination medications can benefit patients requiring multiple agents to lower their intraocular pressure (IOP), but combining agents with complementary mechanisms of action is challenging if their dosing frequency differs. This study compares in vivo pharmacokinetic and ocular tolerability of bimatoprost 0.01% ophthalmic solutions dosed once or twice daily. Reports of twice-daily dosing in glaucoma patients are also reviewed. Methods New Zealand White rabbits were administered bimatoprost 0.01% monotherapy or fixed-combination bimatoprost 0.01%/brimonidine 0.1%, once or twice daily in both eyes for 4 days. Ocular tissues were harvested and analyzed by liquid chromatography-tandem mass spectrometry. The pharmacokinetic parameters calculated included maximum observed concentration, time to maximum concentration, and area under the concentration-time curve. Results Due to extensive metabolism, bimatoprost concentration was below the quantitation limit by 1 hour post-dose in all samples. Bimatoprost acid exposure, however, could be measured up to 6–8 hours post-dose and was similar in the aqueous humor and iris-ciliary body (pharmacological site of action) of animals treated once or twice daily with either bimatoprost 0.01% or fixed-combination bimatoprost 0.01%/brimonidine 0.1%. Increasing dosage frequency in rabbits did not raise the incidence of drug-related conjunctival hyperemia (most common adverse event associated with bimatoprost use in humans), suggesting comparable ocular tolerability of the once- and twice-daily regimens for each formulation. Conclusion Bimatoprost 0.01% administered once or twice daily as monotherapy and in fixed-combination with brimonidine 0.1% in rabbits show similar pharmacokinetic profiles of bimatoprost acid, especially in the iris-ciliary body. Key findings from previous clinical studies suggest that by varying the concentration of benzalkonium chloride (a preservative with corneal penetration-enhancing properties

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

Questioning the rule of thumb: can verbal tasks be administered during the CVLT-II delay interval?

Science.gov (United States)

Williams, Bethany R; Donovick, Peter J

2008-09-01

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

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.

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

2018-01-01

Full Text Available Aim: To study the effects of omalizumab in chronic spontaneous urticaria in Indian patients. Setting and Design: The study was conducted in a tertiary care centre and it was retrospective and descriptive in nature. Material and Methods: We analysed the data of patients who were administered omalizumab between June 2014 and June 2015 for the management of refractory chronic spontaneous urticaria at our centre. Omalizumab was used in those patients who did not respond to updosing of antihistaminics and cyclosporine. Omalizumab was used in dose of 300 mg per month for 3 doses. Results: Twenty-four patients were administered omalizumab during the study period. Average age of the patients was 36.54 years, female:male ratio was 1.4:1, mean duration of disease was 20.66 months, and autologous serum skin test was positive in 33% of studied individuals. Ninety six percent of cases showed response to treatment in our study. Remission was seen in 25% of patients, 50% showed satisfactory response, and 20.83% showed partial response. Average UAS7 scoring before starting omalizumab in preceding week was 24.4. Average UAS7, 2 weeks after starting omalizumab was 4 in responsive patients. Conclusion: Omalizumab is safe and effective treatment for the management of chronic spontaneous urticaria. It can be used in Indian setting after failure to other third-line therapies such as addition of montelukast and cyclosporine due to high cost of treatment.

Association between systemically administered radioisotopes and subsequent malignant disease

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

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

Our understanding of the active role that astrocytes play in modulating neuronal function and behavior is rapidly expanding, but little is known about the role that astrocytes may play in drug-seeking behavior for commonly abused substances. Given that the nucleus accumbens is critically involved in substance abuse and motivation, we sought to determine whether nucleus accumbens astrocytes influence the motivation to self-administer ethanol following abstinence. We found that the packing density of astrocytes that were expressing glial fibrillary acidic protein increased in the nucleus accumbens core (NAcore) during abstinence from EtOH self-administration. No change was observed in the nucleus accumbens shell. This increased NAcore astrocyte density positively correlated with the motivation for ethanol. Astrocytes can communicate with one another and influence neuronal activity through gap-junction hemichannels. Because of this, the effect of blocking gap-junction hemichannels on the motivation for ethanol was examined. The motivation to self-administer ethanol after 3 weeks abstinence was increased following microinjection of gap-junction hemichannel blockers into the NAcore at doses that block both neuronal and astrocytic channels. In contrast, no effect was observed following microinjection of doses that are not thought to block astrocytic channels or following microinjection of either dose into the nucleus accumbens shell. Additionally, the motivation for sucrose after 3 weeks abstinence was unaffected by NAcore gap-junction hemichannel blockers. Next, Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) were selectively expressed in NAcore astrocytes to test the effect of astrocyte stimulation. DREADD activation increased cytosolic calcium in primary astrocytes, facilitated responding for rewarding brain stimulation, and reduced the motivation for ethanol after 3 weeks abstinence. This is the first work to modulate drug-seeking behavior with

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

Paroxysmal Hypnogenic Dyskinesia Responsive to Doxylamine: A Case Report

Daniel M. Williams

2012-01-01

Full Text Available Paroxysmal hypnogenic dyskinesia is a rare clinical entity characterized by intermittent dystonia and choreoathetoid movements that begin exclusively during sleep, often with consciousness preserved once the patient is awakened during the episodes. They occur almost every night and are often misdiagnosed as sleeping disorders. Paroxysmal hypnogenic dyskinesia is currently known to be a form of frontal lobe epilepsy, but not in all cases. We present a 19-year-old male patient with paroxysmal hypnogenic dyskinesia who responded to antihistamines. This supports an alternative theory from 1977 (before the cases had been adequately described that the disorder lies in dysregulation in the basal ganglia. This description now appears similar to acute dystonic reactions such as extrapyramidal symptoms from antipsychotic medications, which also respond to antihistamines.

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.

2011-04-01

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.

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

For example, using a concentration of 7 mg/g GNP, significant DEF (>20%) could be achieved 5 mm from a GBS after 5, 12, 25, 46, 72, 120, and 195 days, respectively, for GNP sizes of 2, 5, 10, 20, 30, and 50 nm and for 80 nm when treating with I-125. Conclusions: Analyses showed that using Cs-131 provides the highest dose enhancement to tumor voxels. However, given its relatively longer half-life, I-125 presents the most flexibility for customizing the dose enhancement as a function of GNP size. These findings provide a useful reference for further work toward development of potential new brachytherapy application

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.

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

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

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

Full Text Available Jie Shen,1 Margot L Goodkin,2 Warren Tong,2 Mayssa Attar3 1Clinical Pharmacology, 2Clinical Development, 3Clinical Pharmacology, Metabolism and Immunology, Allergan plc, Irvine, CA, USA Purpose: Fixed-combination medications can benefit patients requiring multiple agents to lower their intraocular pressure (IOP, but combining agents with complementary mechanisms of action is challenging if their dosing frequency differs. This study compares in vivo pharmacokinetic and ocular tolerability of bimatoprost 0.01% ophthalmic solutions dosed once or twice daily. Reports of twice-daily dosing in glaucoma patients are also reviewed.Methods: New Zealand White rabbits were administered bimatoprost 0.01% monotherapy or fixed-combination bimatoprost 0.01%/brimonidine 0.1%, once or twice daily in both eyes for 4 days. Ocular tissues were harvested and analyzed by liquid chromatography-tandem mass spectrometry. The pharmacokinetic parameters calculated included maximum observed concentration, time to maximum concentration, and area under the concentration-time curve.Results: Due to extensive metabolism, bimatoprost concentration was below the quantitation limit by 1 hour post-dose in all samples. Bimatoprost acid exposure, however, could be measured up to 6–8 hours post-dose and was similar in the aqueous humor and iris-ciliary body (pharmacological site of action of animals treated once or twice daily with either bimatoprost 0.01% or fixed-combination bimatoprost 0.01%/brimonidine 0.1%. Increasing dosage frequency in rabbits did not raise the incidence of drug-related conjunctival hyperemia (most common adverse event associated with bimatoprost use in humans, suggesting comparable ocular tolerability of the once- and twice-daily regimens for each formulation.Conclusion: Bimatoprost 0.01% administered once or twice daily as monotherapy and in fixed-combination with brimonidine 0.1% in rabbits show similar pharmacokinetic profiles of bimatoprost acid

Full Text Available Andrew Cooke,1 Adeeb Bulkhi,1,2 Thomas B Casale1 1Department of Internal Medicine, Division of Allergy and Immunology, University of South Florida, Tampa, FL, USA; 2Department of Internal Medicine, College of Medicine, Umm Al-Qura University, Makkah, Saudi Arabia Abstract: Chronic urticaria (CU is a common condition faced by many clinicians. CU has been estimated to affect approximately 0.5%–1% of the population, with nearly 20% of sufferers remaining symptomatic 20 years after onset. Antihistamines are the first-line therapy for CU. Unfortunately, nearly half of these patients will fail this first-line therapy and require other medication, including immune response modifiers or biologics. Recent advances in our understanding of urticarial disorders have led to more targeted therapeutic options for CU and other urticarial diseases. The specific biologic agents most investigated for antihistamine-refractory CU are omalizumab, rituximab, and intravenous immunoglobulin (IVIG. Of these, the anti-IgE monoclonal antibody omalizumab is the best studied, and has recently been approved for the management of CU. Other agents, such as interleukin-1 inhibitors, have proved beneficial for Schnitzler syndrome and cryopyrin-associated periodic syndromes (CAPS, diseases associated with urticaria. This review summarizes the relevant data regarding the efficacy of biologics in antihistamine-refractory CU.

Schinus terebinthifolius Raddi (Anacardiaceae), popularly known as red aroeira, is used in traditional medicine to treat inflammatory, gastric, and respiratory disorders. The aim of this study was to evaluate the antihistaminic activity of S. terebinthifolius (St) bark extract by using in vivo and in vitro experimental models. The effects of St were investigated on contractions induced by histamine, carbachol, and potassium chloride in isolated guinea pig ileum. St was also studied in response to hind paw edema induced by histamine in rats. Experiments revealed that although St (250, 500, and 1,000  µ g/mL) reduced the histamine-induced contractions by 9.1 ± 1.8, 50.2 ± 2.0, and 68.9 ± 2.0%, respectively, it did not inhibit contractions induced by carbachol or KCl. The association of St (250 and 500  µ g/mL) with hydroxyzine, an H 1 -antihistamine (0.125 and 0.250  µ M), increased the inhibitory effect to 67.0 ± 3.2 and 85.1 ± 2.1%, respectively. Moreover, St (100, 200, and 400 mg/kg) decreased paw edema from its peak by 33.9, 48.4, and 54.8%, respectively, whereas hydroxyzine (70 mg/kg) inhibited the peak edema by 56.5%. Altogether, the results suggest that the bark extract of S. terebinthifolius has an antihistaminic effect (H 1 ).

2015-03-01

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.

Full Text Available Introduction . Dermatitis herpetiformis (Duhring disease is an autoimmune blistering subepidermal dermatosis characterized by pruritic polymorphic skin eruption accompanied by a clinically asymptomatic gluten-sensitive enteropathy. The etiopathogenesis of the disease is associated with the presence of antibodies against tissue and epidermal transglutaminase. Diagnosis is based on direct immunopathological examination in which granular IgA deposits on the top of dermal papillae are detected. Sulfones are effective in the therapy of skin changes. Objective . The aim of the study is to present difficulties in evaluation of clinical picture, diagnosis and treatment, and monitoring the safety of the therapy in Duhring disease on the basis of three own cases. Case report . Case 1. 37-year-old patient. Itchy skin lesions occurred in mid-2012 and have been treated until now with antihistamines and local corticosteroids without improvement. The diagnosis of dermatitis herpetiformis was established on the basis of direct immunopathology test. Treated with gluten-free diet and dapsone 100 mg/day with improvement. Case 2. 62-year-old patient, in whom the first itchy eruption appeared in October 2012. Treated with antihistamines and topical corticosteroids without improvement. In laboratory examinations elevated level of IgE and triglycerides was found. Histopathological and immunological examinations confirmed the diagnosis of dermatitis herpetiformis. Treated with gluten-free diet and dapsone 150 mg/day with improvement. Case 3. 58-year-old patient. The first changes of typical morphology appeared about 2 years ago. The patient was treated with antihistamines and corticosteroids without improvement. Laboratory tests confirmed the diagnosis of Duhring disease. The introduction of gluten-free diet and dapsone 100 mg/day caused regression of skin changes. Conclusions . Our cases, treated for a long time as eczematous changes, despite the lack of improvement

2014-10-01

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.

Serum biochemical activities and muscular soreness in transported goats administered with ascorbic acid during the hot-dry season

Directory of Open Access Journals (Sweden)

Ndazo S Minka

2010-12-01

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.

Post-burn itch is a distressing symptom in burns rehabilitation and its treatment often proves frustrating for the patient and the multidisciplinary burns team. Traditionally, the mainstay of antipruritic therapy for decades has been antihistamines and massage with emollients. With a better understanding of the neurophysiology of itch emerged a new dimension in the treatment of post-burn pruritus. Gabapentin, a centrally modulating anti-epileptic agent and α2δ ligand, proved in clinical trials to be immensely better in the treatment of post-burn pruritus. Pregabalin is a newer structural analog of gabapentin. It has a much better anxiolytic effect and pharmacokinetic profile as compared to gabapentin. The current study was initiated to specifically study the role of pregabalin in relieving post-burn itch as this has never been investigated before. This double blind, randomized and placebo controlled study had four arms and was carried out on 80 adult patients (20 each). The four arms were: pregabalin, cetirizine with pheniramine maleate, combination of pregabalin, cetirizine and pheniramine maleate, and placebo (vit. B comp.). Massage with coconut oil was integral to all groups. Drug dosage was determined by initial VAS (visual analog scale) scores. All groups matched in demographic data and initial VAS scores. VAS scores were evaluated over next 28 days (days 3, 7, 14, 21 and 28). In patients with mild itch (VAS scores 2-5) or moderate itch (VAS scores 6-8) near complete remission of itch was seen in combination group and pregabalin group where the response was comparable and close to 95%. This was significantly better response than antihistaminic combination or massage alone. However, massage alone was sufficient in decreasing mean scores in mild itch, in a large percentage of patients. Amongst the patients with severe itch (VAS scores 9-10), 3/6 and 6/7 patients dropped out of trial in the antihistaminic and placebo groups, respectively. Combination therapy

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

Acetaminophen (paracetamol) is a widely used analgesic, but its sites and mechanisms of action remain incompletely understood. Recent studies have separately implicated spinal adenosine A(1) receptors (A(1)Rs) and serotonin 5-HT(7) receptors (5-HT(7)Rs) in the antinociceptive effects of systemically administered acetaminophen. In the present study, we determined whether these two actions are linked by delivering a selective 5-HT(7)R antagonist to the spinal cord of mice and examining nociception using the formalin 2% model. In normal and A(1)R wild type mice, antinociception by systemic (i.p.) acetaminophen 300mg/kg was reduced by intrathecal (i.t.) delivery of the selective 5-HT(7)R antagonist SB269970 3μg. In mice lacking A(1)Rs, i.t. SB269970 did not reverse antinociception by systemic acetaminophen, indicating a link between spinal 5-HT(7)R and A(1)R mechanisms. We also explored potential roles of peripheral A(1)Rs in antinociception by acetaminophen administered both locally and systemically. In normal mice, intraplantar (i.pl.) acetaminophen 200μg produced antinociception in the formalin test, and this was blocked by co-administration of the selective A(1)R antagonist DPCPX 4.5μg. Acetaminophen administered into the contralateral hindpaw had no effect, indicating a local peripheral action. When acetaminophen was administered systemically, its antinociceptive effect was reversed by i.pl. DPCPX in normal mice; this was also observed in A(1)R wild type mice, but not in those lacking A(1)Rs. In summary, we demonstrate a link between spinal 5-HT(7)Rs and A(1)Rs in the spinal cord relevant to antinociception by systemic acetaminophen. Furthermore, we implicate peripheral A(1)Rs in the antinociceptive effects of locally- and systemically-administered acetaminophen. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

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

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

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

Objective Among elderly patients with chronic obstructive pulmonary disease (COPD), there are some patients who cannot inhale tiotropium via Respimat ® due to poor hand-lung coordination. This study aimed to examine whether or not tiotropium inhalation therapy using Respimat ® with a spacer increased the forced expiratory volume in 1 s (FEV 1 ) in patients with COPD. Methods A randomized, crossover, single-center study was conducted in 18 patients with stable COPD. Tiotropium (5 μg) via Respimat ® with or without a spacer (AeroChamber ® ) was administered for 2 weeks. Following a 2-week washout period using a transdermal tulobuterol patch (2 mg per day), participants were then crossed over to the other inhalation therapy with respect to spacer use. The trough FEV 1 was measured at every visit using a spirometer. A questionnaire regarding inhalation therapy was administered to patients at the final visit. Results The administration of tiotropium via Respimat ® both with and without a spacer significantly increased the trough FEV 1 from baseline during each treatment period, with mean differences of 115.0±169.6 mL and 92.8±128.1 mL, respectively. There was no significant difference in the change in the trough FEV 1 between the 2 procedures (p=0.66). A total of 86% of patients reported that inhalation using a spacer was not difficult, and more than half also rated both the usage and maintenance of the AeroChamber ® as easy. Conclusion Tiotropium inhalation therapy administered via Respimat ® using a spacer exerted a bronchodilatory effect similar to that observed with tiotropium Respimat ® alone.

Orally administered bisphosphonate drugs (i.e., alendronate, etidronate, risedronate) can reduce the risk of vertebral fracture. However, only alendronate and risedronate have proven efficacy in reducing the risk of hip fracture. We sought to examine the comparative effectiveness of orally administered bisphosphonate drugs in reducing hip fractures among older adults. We identified new users of orally administered bisphosphonate drugs in British Columbia and Ontario between 2001 and 2008. We used province- and sex-specific propensity score-matching strategies to maximize comparability between exposure groups. We used Cox proportional hazards models to compare time-to-hip fracture within 1 year of treatment between exposures by sex in each province. Our secondary analyses considered hip fracture rates within 2 and 3 years' follow-up. We used alendronate as the reference for all comparisons and pooled provincial estimates using random effects variance-weighted meta-analysis. We identified 321 755 patients who were eligible for inclusion in the study. We found little difference in fracture rates between men (pooled hazard ratio [HR] 0.94, 95% confidence interval [CI] 0.74-1.14) or women (pooled HR 1.15, 95% CI 0.73-1.56) taking risedronate and those taking alendronate. We similarly identified little difference in fracture rates between women taking etidronate and those taking alendronate (pooled HR 1.00, 95% CI 0.82-1.18). However, we identified lower rates of hip fracture among men taking etidronate relative to alendronate (pooled HR 0.77, 95% CI 0.60-0.94). Results extended to 2 and 3 years' follow-up were similar. However, with 3 years' follow-up, rates of hip fracture were lower among women in British Columbia who had taken alendronate. We identified little overall difference between alendronate and risedronate in reducing the risk of hip fracture in men or women. Our finding that etidronate is associated with lower fracture risk among men is likely due to

Obtaining valid and reliable estimates of usual dietary intake at a reasonable cost is a challenge in school-based nutrition research. The Automated Self-Administered 24-Hour Dietary Recall for Children, 2014 version (ASA24 Kids-2014), a self-administered, computerized 24-hour dietary recall, offers improved feasibility over traditional interviewer-administered 24-hour recalls. This mixed-methods study examined ASA24 Kids-2014's validity for measuring dietary intake from National School Lunch Program lunches. After 24% attrition, 96 middle-school students from three urban schools in eastern Pennsylvania participated in the study. A subsample of 27 participants completed qualitative interviews. Data were collected in the spring of 2014. Self-reported ASA24 Kids-2014 data were compared to direct observations of school lunch, which served as the criterion measure. Dependent variables included eight meal components selected from the National School Lunch Program guidelines (fruit, vegetables, grains, protein-rich foods, dairy, oils, solid fats, and added sugars). A supplemental interview collected qualitative data regarding students' perceptions of content and substantive validity. The Wilcoxon signed rank test and Spearman's ρ examined criterion-related validity; qualitative content analysis examined content and substantive validity. Participants inaccurately recalled food items eaten at lunch, as 58% of foods were reported in error. However, among foods recalled correctly, no statistically significant differences emerged for estimates of portions consumed for six meal components (fruit, vegetables, grains, protein-rich foods, oils, and added sugars). In addition, statistically significant positive correlations emerged between ASA24 Kids-2014 and direct observation for all estimates. Qualitative data identified students' interest and motivation, comprehension, memory, and English-language fluency as relevant sources of error. Middle school students have difficulty

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.

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.

Ethical dilemmas faced by hospice nurses when administering palliative sedation to patients with terminal cancer.

De Vries, Kay; Plaskota, Marek

2017-04-01

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

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

Kieran, J

2012-02-01

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.

Sucrose has been shown to have analgesic properties when administered to neonates and infants: is there the potential for its use in post-operative pain management?

Science.gov (United States)

Hardcastle, Teresa

2010-01-01

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.

2012-12-05

Experiments were performed with the aim of investigating the effect of packing on erythrocyte osmotic fragility (EOF) and malondialdehyde (MDA) concentration in donkeys, and the effect of ascorbic acid (AA). Twelve apparently healthy donkeys raised under the traditional extensive system served as experimental subjects. Six donkeys administered orally with AA (200 mg/kg) and subjected to packing were used as experimental animals, whilst six others not administered with AA served as controls. Blood samples were collected pre- and post-packing from all the donkeys for the determination of MDA and EOF. At 0.3% Sodium Chloride (NaCl) concentration, the percentage haemolysis was 93.69% ± 2.21% in the control donkeys and the value was significantly (P < 0.05) higher than the value of 71.31% ± 8.33%, recorded in the experimental donkeys. The post-packing MDA concentration obtained in the control donkeys was 39.62 µmol ± 4.16 µmol, and was not significantly different (P > 0.05) from the value of 35.97 µmol ± 2.88 µmol recorded in the experimental donkeys. In conclusion, the increase in haemolysis obtained in the donkeys suggested that packing induced oxidative stress, which was ameliorated by AA administration.

Substantial reduction in the thyroid volume (up to 70-80%) after 131 I therapy of Graves' disease has been demonstrated and reported in the literature. Recently a mathematical model of thyroid mass reduction during the first month after therapy has been developed and a new algorithm for the radiation committed dose calculation has been proposed. Reduction of the thyroid mass and the radiation committed dose to the gland depend on a parameter k, defined for each subject. The calculation of k allows the prediction of the activity to administer, depending on the radiation committed dose chosen by the physician. In this paper a method for calculating k is proposed. The calculated values of k are compared to values derived from measurements of the changes in thyroid mass in twenty-six patients treated by 131 I for Graves' disease. The radiation committed dose to the thyroid can be predicted within 21%, and the radioiodine activity to administer to the patient can be predicted within 22% using the calculated values of k. The thyroid volume reduction during the first month after therapy administration can be also predicted with good accuracy using the calculated values of k. The radiation committed dose and the radioiodine activity to administer were calculated using a new, very simple algorithm. A comparison between the values calculated by this new algorithm and the old, classical Marinelli-Quimby algorithm shows that the new method is more accurate. (author)

The history and progression of treatments for allergic rhinitis.

Ostrom, Nancy K

2014-01-01

This article intends to place new treatments in the context of allergic rhinitis (AR) treatment history. The medical literature was searched for significant advances and changes in AR treatment. Historical data on AR treatment options and management were selected. Reviews of AR management published throughout the 20th century were included to provide context for treatment advances. Modern AR treatment began in the early 20th century with immunotherapy and was soon followed by the emergence of antihistamine therapy in the 1930s. Numerous treatments for AR have been used over the ensuing decades, including decongestants, mast cell stabilizers, and leukotriene receptor antagonists. Topical corticosteroid options were developed the 1950s, and, added to baseline antihistamine therapy, became the foundation of AR treatment. Treatment options were significantly impacted after the 1987 Montreal Protocol, which phased out the use of chlorofluorocarbon propellant aerosols because of environmental concerns. From the mid-1990s until recently, this left only aqueous solution options for intranasal corticosteroids (INSs). The approval of the first hydrofluoroalkane propellant aerosol INSs for AR in 2012 restored a "dry" aerosol treatment option. The first combination intranasal antihistamine/INSs was also approved in 2012, providing a novel treatment option for AR. Treatment of AR has progressed with new therapeutic options now available. This should continue to move forward with agents to alter the allergic mechanism itself and impact the disease burden that has a significant impact on patient outcomes.

The pharmacokinetics of d-chlorpheniramine (CPM), a histamine H1-receptor antagonist, and its ability to inhibit of histamine-induced cutaneous wheal formation, were studied in healthy Thoroughbred horses (n=5). Following an intravenous (IV) dose of 0.5mg/kg bodyweight (BW), plasma drug disposition was very rapid, with the mean terminal half-life and total body clearance calculated as 2.7h and 0.7 L/h/kg, respectively. The observed maximal inhibition of wheal formation following IV doses of 0.1 and 0.5mg/kg BW were 37.8% and 60.6% at 0.5h, respectively. Oral administration of CPM (0.5mg/kg BW) resulted in a bioavailability of 38%, which induced a peak plasma drug concentration at 1h and a maximal inhibition of wheal formation (39%) at 2h. A pharmacokinetic/pharmacodynamic link model showed that CPM in horses has lower efficacy, much lower potency and slightly lower sensitivity than other reported antihistamines. These results indicated that CPM should be administered at frequent intervals or at large dose rates to maintain therapeutic concentrations in horses. Copyright © 2013 Elsevier Ltd.

Fentanyl is frequently used during anesthesia induction. The use of fentanyl can cause cough through different mechanisms. Here, we aimed to investigate effects of pheniramine maleate (PM), an antihistaminic agent, and compare it with lidocaine on fentanyl induced cough. This is a randomized double-blind prospective clinical study of ASA I-II, 120 patients scheduled for elective abdominal surgery. Patients were administered drugs intravenously and randomly allocated into three groups: Group C (2 ml 0.9 % normal saline), Group L (1mg/kg lidocaine), and Group F (PM 45.5 mg). 90 seconds after administration, 2µ/kg fentanyl was applied in three seconds to all patients. Severity of cough (mild: 1-2, moderate: 3-5, severe> 5), time of the cough and vital parameters were recorded 90 seconds after fentanyl injection. Eight patients (25%) in Group C had fentanyl induced cough whereas three patients (7.5%) in Group L and one patient (2.5%) in Group F experienced this phenomenon. There was statistically significant difference between Group F and Group C (p0.05). Pheniramine Maleate 45.5 mg is better that placebo and as effective as lidocaine to prevent fentanyl induced cough.

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.

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.

Treating rhinitis in the older population: special considerations

Directory of Open Access Journals (Sweden)

Slavin Raymond G

2009-12-01

Full Text Available Abstract Rhinitis in the elderly is a common but often neglected condition. Structural changes in the nose associated with aging, predisposes the elderly to rhinitis. There are a number of specific factors that affect medical treatment of the elderly including polypharmacy, cognitive dysfunction, changes in body composition, impairment of liver and renal function and the cost of medications in the face of limited resources. Rhinitis in the elderly can be placed in several categories and treatment should be appropriate for each condition. The most important aim is to moisten the nasal mucosa since the nose of the elderly is so dry. Great caution should be used in treatment with first generation antihistamines and decongestants. Medications generally well tolerated by the elderly are second generation antihistamines, intra-nasal anti-inflammatory agents, leukotriene modifiers and iprapropium nasal spray.

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

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

Cormack, John; Shearer, Jane

1998-03-01

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

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.

Successful antiretroviral therapy (ART) relies on the optimal level of ART adherence to achieve reliable viral suppression, avert HIV drug resistance, and prevent avoidable deaths. It has been shown that there are various groups of people living with HIV at high-risk of non-adherence to ART in sub-Saharan Africa. The objective of this study was to examine the cost effectiveness and value-of-information of directly administered antiretroviral therapy (DAART) versus self-administered ART among people living with HIV, at high risk of non-adherence to ART in sub-Saharan Africa. A Markov model was developed that describes the transition between HIV stages based on the CD4 count, along with direct costs, quality of life and the mortality rate associated with DAART in comparison with self-administered ART. Data used in the model were derived from the published literature. A health system perspective was employed using a life-time time horizon. Probabilistic sensitivity analysis was performed to determine the impact of parameter uncertainty. Value of information analysis was also conducted. The expected cost of self-administered ART and DAART were $5,200 and $15,500 and the expected QALYs gained were 8.52 and 9.75 respectively, giving an incremental cost effectiveness ratio of $8,400 per QALY gained. The analysis demonstrated that the annual cost DAART needs to be priced below $200 per patient to be cost-effective. The probability that DAART was cost-effective was 1% for a willingness to pay threshold of $5,096 for sub-Saharan Africa. The value of information associated with the cost of DAART and its effectiveness was substantial. From the perspective of the health care payer in sub-Saharan Africa, DAART cannot be regarded as cost-effective based on current information. The value of information analysis showed that further research will be worthwhile and potentially cost-effective in resolving the uncertainty about whether or not to adopt DAART.

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

Administering and Detecting Protein Marks on Arthropods for Dispersal Research.

Science.gov (United States)

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.

Fractionation of radioactivity in the milk of goats administered 14C-aflatoxin B1

Goto, T.; Hsieh, D.P.

1985-01-01

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