    Previous investigators have shown significant benefit using CO{sub 2} for bowel insufflation. Others have suggested that the long-acting smooth muscle relaxant, Mebeverine, may be of benefit. We subjected this to a randomised double-blind trial. A total of 181 outpatients were randomised to receive either Mebeverine or placebo as pre-medication, and either air or CO{sub 2} for bowel insufflation, thus creating four treatment groups. Visual-analogue lines were used to record pain scores before, during, and up to 8 h following the enema. All groups showed increased pain scores during the enema, with peak pain scores at the end of the examination, falling to baseline scores by 8 h. Patients receiving the combination of C0{sub 2} and placebo had significantly lower pain scores at 1 and 4 h (P=0.00 and P=0.014, respectively; Kruskal-Wallis test) compared with all other groups. Having Mebeverine as a pre-medication did not significantly lower pain scores compared with placebo, and decreased the amount of benefit received from the CO{sub 2}. We confirm that CO{sub 2} is of benefit in decreasing pain during barium enema, and we recommend its routine use to improve the comfort of patients. Mebeverine is not of benefit, and its use as a pre-medication for enemas is not recommended. (orig.)

    Treatment-resistant paranoid schizophrenia is often addressed with long-term intramuscular preparations of conventional antipsychotics (haloperidol and fluphenazine), which can be associated with the development of painful, lumpy nodules at the injection site. In this article, we present a case example of a 58-year-old male patient with paranoid schizophrenia who was treated with risperidone long-acting injection given into the deltoid muscle instead of the US Food and Drug Administration (FD...

    Schizophrenia is one of the most expensive psychiatric conditions because of high direct and indirect costs associated with the nature of the illness, its resistance to treatment and the consequences of relapse. Long-acting risperidone is a new formulation of an atypical antipsychotic drug that also offers the improvements in compliance associated with haloperidol depot. The aim of this simulation study was to compare the benefits and costs of three pharmacological treatment strategies comprising first-line treatment with long-acting risperidone injection, a haloperidol depot or an oral atypical antipsychotic agent, over a 5-year period in Germany. A discrete event simulation model was developed to compare three treatment scenarios from the perspective of major third-party payers (sickness funds and social security 'Sozialversicherung'). The scenarios comprised first-line treatment with haloperidol depot (scenario 1), long-acting risperidone (scenario 2) and oral olanzapine (scenario 3). Switches to second or third-line options were allowed when side-effects occurred or a patient suffered more than a fixed number of relapses. The model accounted for fixed patient characteristics, and on the basis of these, simulated patient histories according to several time-dependent variables. The time horizon for this model was limited to 5 years, and in accordance with German guidelines, costs and effects were discounted by between 3 and 10%. Direct costs included medication, type of physician visits and treatment location. Indirect costs were not included. Information on treatment alternatives, transition probabilities, model structure and healthcare utilization were derived from the literature and an expert panel. Outcomes were expressed in terms of the number and duration of psychotic episodes, cumulative symptom scores, costs, and quality-adjusted life-years (QALY). Univariate sensitivity analyses were carried out, as were subgroup analyses based on disease severity and

    In patients with type-2 diabetes receiving oral antidiabetic drugs (OADs), the addition of insulin is frequently required to achieve sufficient control over blood glucose levels. It is, however, difficult to predict if, when and in which patients insulin therapy will be needed. We aimed to identify patient related variables associated with the addition of basal insulin to oral therapy resulting in a basal supported oral therapy (BOT). DIVE (DIabetes Versorgungs-Evaluation) is a prospective, observational, multi-centre diabetes registry established in Germany in 2011. For the present explorative analysis, 31,008 patients with type-2 diabetes prescribed at least one OAD were included. Patients who had previously received insulin and those over 90 years old were excluded. The event of interest was defined as the initiation of BOT during the observational period. Cause-specific Cox proportional hazards models based on a competing risk framework were applied for risk quantification. Multivariable adjusted hazard ratios demonstrated that longer diabetes duration, higher BMI, poorer glycaemic control, documentation of any micro- or macrovascular comorbidity, the presence of concomitant non-antidiabetic pharmacotherapies, and greater numbers of prescribed OADs increased the likelihood of BOT initiation. On the other hand BOT initiation was less likely in patients with older age and female gender. Analysing the likelihood of OAD termination without initiation of BOT provided supportive evidence for the variables predictive of BOT initiation. Analysis of the DIVE registry has resulted in the identification of a number of factors that may be predictive for the initiation of BOT for type-2 diabetes patients initially prescribed one or more OADs. Poor glycaemic control, the presence of vascular comorbidities and concomitant medications, and a greater number of OADs were all detected to increase the risk of a switch to BOT. Female gender and younger age showed protective

    The aim was to investigate the effect of the long-acting β2-adrenergic agonist formoterol on muscle strength and power output, muscle metabolism, and phosphorylation of CaMKII Thr(287) and FXYD1 during maximal sprinting. In a double-blind crossover study, 13 males [V̇o2 max: 45.0 ± 0.2 (means ± SE) ml·min(-1)·kg(-1)] performed a 30-s cycle ergometer sprint after inhalation of either 54 μg of formoterol (FOR) or placebo (PLA). Before and after the sprint, muscle biopsies were collected from vastus lateralis and maximal voluntary contraction (MVC), and contractile properties of quadriceps were measured. Oxygen uptake was measured during the sprint. During the sprint, peak power, mean power, and end power were 4.6 ± 0.8, 3.9 ± 1.1, and 9.5 ± 3.2% higher (P power output during maximal sprinting is associated with increased rates of glycogenolysis and glycolysis that may counteract development of fatigue.

    Review oral modified release drug forms of beta-adrenoblocker metoprolol which is used in arterial hypertension and ischemic heart disease is presented. Metoprolol has salts such as tartrate which is used for production of immediate release (IR) and sustained release (SR) forms and succinate used for production of controlled release form (CR/XL). Metoprolol SR has monolith matrix type, metoprolol CR/XL-system of multiple pellets. Effect of metoprolol tartrate (IR) on mortality was demonstrated in a number of studies in patients with arterial hypertension (AH) (MAPHY), myocardial infarction (SMT, GMT, MIAMI), dilated cardiomyopathy and heart failure (MDC). Studies of efficacy of metoprolol SR are scarce. Antihypertensive efficacy of metoprolol SR in patients with AH did not exceed that of a metoprolol IR or CR/XL. First retrospective analysis of efficacy of metoprolol tartrate and succinate (CR/XL) in patients after myocardial infarction allowed to obtain comparable results of 34% mortality lowering. In a prospective study in patients with chronic heart failure (COMET) metoprolol tartrate IR was not superior to carvedilol when mortality lowering was concerned. At the same time administration of controlled release metoprolol (CR/XL) in 2 large clinical trials (RESOLVD, MERITAHF) was advantageous in patients with chronic heart failure relative to lowering of mortality and rate of hospitalizations. A novel controlled release form of metoprolol has been created as a tartrate salt on the basis of pellet technology (CD/ERT) and its bioequivalence to metoprolol CR/XL has been proved.

    The electronic Schizophrenia Treatment Adherence Registry (e-STAR) is a prospective, observational study of patients with schizophrenia designed to evaluate long-term treatment outcomes in routine clinical practice. Parameters were assessed at baseline and at 3 month intervals for 2 years in patients initiated on risperidone long-acting injection (RLAI) (n=1345) or a new oral antipsychotic (AP) (n=277; 35.7% and 36.5% on risperidone and olanzapine, respectively) in Spain. Hospitalization prior to therapy was assessed by a retrospective chart review. At 24 months, treatment retention (81.8% for RLAI versus 63.4% for oral APs, p<0.0001) and reduction in Clinical Global Impression Severity scores (-1.14 for RLAI versus -0.94 for APs, p=0.0165) were significantly higher with RLAI. Compared to the pre-switch period, RLAI patients had greater reductions in the number (reduction of 0.37 stays per patient versus 0.2, p<0.05) and days (18.74 versus 13.02, p<0.01) of hospitalizations at 24 months than oral AP patients. This 2 year, prospective, observational study showed that, compared to oral antipsychotics, RLAI was associated with better treatment retention, greater improvement in clinical symptoms and functioning, and greater reduction in hospital stays and days in hospital in patients with schizophrenia. Improved treatment adherence, increased efficacy and reduced hospitalization with RLAI offer the opportunity of substantial therapeutic improvement in schizophrenia.

    Optimization of a previously disclosed sorbitol dehydrogenase inhibitor (SDI, II) for potency and duration of action was achieved by replacing the metabolically labile N,N-dimethylsulfamoyl group with a variety of heterocycles. Specifically, this effort led to a series of novel, in vitro potent SDIs with longer serum half-lives and acceptable in vivo activity in acutely diabetic rats (e.g., 62, 67, and 69). However, the desired in vivo potency in chronically diabetic rats, ED(90) < or = 5 mg/kg/day, was achieved only through further modification of the piperazine linker. Several members of this family, including 86, showed better than the targeted potency with ED(90) values of 1-2 mg/kg/day. Compound 86 was further profiled and found to be a selective inhibitor of sorbitol dehydrogenase, with excellent pharmacodynamic/pharmacokinetic properties, demonstrating normalization of sciatic nerve fructose in a chronically diabetic rat model for approximately 17 h, when administered orally at a single dose of 2 mg/kg/day.

    Eperisone and afloqualone act by relaxing both skeletal and vascular smooth muscles to improve circulation and suppress pain reflex. These drugs are typically prescribed with non-steroidal anti-inflammatory drugs (NSAIDs) as painkillers. However, there have been no reports on serious adverse reactions to oral muscle relaxants; and this is the first report to describe three allergic reactions caused by eperisone and afloqualone. All three patients had histories of allergic reactions after oral intake of multiple painkillers, including oral muscle relaxants and NSAIDs, for chronic muscle pain. An open-label oral challenge test was performed with each drug to confirm which drugs caused the systemic reactions. All patients experienced the same reactions within one hour after oral intake of eperisone or afloqualone. The severity of these reactions ranged from laryngeal edema to hypotension. To confirm that the systemic reaction was caused by eperisone or afloqualone, skin prick testing and intradermal skin tests were performed with eperisone or afloqualone extract in vivo, and basophil activity tests were performed after stimulation with these drugs in vitro. In one patient with laryngeal edema, the intradermal test with afloqualone extract had a positive result, and CD63 expression levels on basophils increased in a dose-dependent manner by stimulation with afloqualone. We report three allergic reactions caused by oral muscle relaxants that might be mediated by non-immunoglobulin E-mediated responses. Since oral muscle relaxants such as eperisone and afloqualone are commonly prescribed for chronic muscle pain and can induce severe allergic reactions, we should prescribe them carefully.

Nowadays, current therapeutic regimens rely on daily subcutaneous GH injections that could be burdensome and inconvenient to pediatric patients. As expected with any long-term parenteral pharmacological treatment, these daily regimens may promote nonadherence, poor compliance, treatment abandonment and/or suboptimal clinical outcomes. In order to improve patient and caregiver acceptance of proposed regimens, simplified dosing schedules could potentially aid in reducing poor compliance and maximize the therapeutic end results. Long-acting GH formulations have been designed and perfected over the last two decades, and currently there are several formulations in advanced stages of research as a reasonable attempt to improve patient's adherence to GH treatment. A long-acting GH preparation allowing for reduced injection frequency is likely to improve treatment adherence and to decrease the distress and inconvenience associated with daily injections. This review presents an update about the status of current and recent efforts that have enabled the formulation of sustained-release, long-acting rhGH as it has been longed for many years in the pediatric endocrinology field.

    Sarcopenia is a geriatric syndrome characterized by progressive and generalized loss of skeletal muscle mass and function. Reported prevalence of this geriatric syndrome, differs depending on the definition, the population and the method used to identify sarcopenia. The causes of sarcopenia are multifactorial, and can include genetic influence, immobility or disuse, endocrine factors, inflammation and nutritional deficiencies. These disorders involve an imbalance between anabolic and catabolic pathways that rules muscle mass. Many drugs taken regularly for common conditions may interact with some mechanisms that can alter the balance between protein synthesis and degradation. This may lead to a harmful or a beneficial effect on muscle mass and strength. Widely prescribed drugs could play an important role during the time of onset and development of sarcopenia. In this paper, we reviewed the current understanding of how can drugs contribute positively or negatively on sarcopenia and muscle wasting. We decided to focus this review on oral common drugs, which are usually prescribed in older adults, leaving aside other drugs as hormone therapy. © 2016 S. Karger AG, Basel.

    Full Text Available JP LindenmayerDepartment of Psychiatry, New York University School of Medicine, New York NY, USAAbstract: Medication non-adherence in patients with schizophrenia continues to be a significant problem and threatens successful treatment outcomes. Medication non-adherence is often associated with negative consequences, including symptom exacerbation, more frequent emergency room visits, re-hospitalizations and relapse. Long-acting injectable (LAI forms of antipsychotics allow for rapid identification of non-adherence, obviate the need for the patient to take the medication on a daily basis and increase adherence to some significant degree. Eli Lilly has developed a long-acting depot formulation of olanzapine, olanzapine pamoate, which has recently been approved by the FDA for the US market, and which will be reviewed here. Olanzapine LAI appears to be an effective antipsychotic at dosages of 210 mg every 2 weeks, 300 mg every 2 weeks and 405 mg every 4 weeks in patients with acute schizophrenia, and at 150 mg every 2 weeks, 300 mg every 2 weeks and at 405 mg every 4 weeks for the maintenance treatment of stable patients. Oral supplementation appears not to be needed, particularly not at the onset of treatment with the LAI as is necessary with risperidone LAI. Its efficacy is in general comparable to the efficacy seen with oral olanzapine at a corresponding dose. The side effect profile is also comparable to the side effects observed with oral olanzapine, including lower rates of extrapyramidal symptoms, prolactin elevation and cardiovascular side effects, but significant metabolic effects. The latter include significant weight gain, lipid abnormalities and glucose dysregulation. While the injection site adverse events are overall mild, the most significant serious adverse event is the post-injection delirium sedation syndrome (PDSS. While rare, this syndrome results from inadvertent intravascular injection of olanzapine LAI and can cause a range of

    Although the use of oral risperidone in children and adolescents has been well studied, there is little information on the intramuscular use of long-acting injectable risperidone (LAIR). The aims of this study were to investigate the effectiveness and adverse effects of LAIR in children and adolescents with conduct disorder, bipolar disorder, and schizophrenia. In total, 42 patients (age range 12-17 years) who were non-adherent to oral antipsychotic drugs, received 25 mg/day of LAIR intramuscularly every 2 weeks. The drug was administered at least four times and up to 66 times (median drug use: 9.50 times). The effectiveness and adverse effects of the treatment were examined. There was an improvement in 13 (92.8%) of the 14 patients diagnosed with bipolar disorder, in 25 (78.1%) of 32 patients diagnosed with conduct disorder and in one (50%) of two patients diagnosed with schizophrenia. Six patients had comorbid conduct disorder and bipolar disorder. Totally, 81% of the patients improved with LAIR. Weight-gain, daytime somnolence, muscle stiffness and spasms, impaired concentration, and fatigue were the most common side effects through the whole sample. Menstrual problems were common in girls. In the study, 57.1% of the patients continued to receive their injections regularly until the end of the treatment, under physician control. A total of 16.7% discontinued the treatment due to non-adherence. The LAIR treatment was terminated in 26.2% of the patients, due to weight-gain, dystonia, and galactorrhea. In children and adolescents with conduct disorder, bipolar disorder and schizophrenia who show noncompliance with oral drugs, LAIR may improve treatment compliance. LAIR is a reliable treatment in terms of its effectiveness. Weight-gain, dystonia, and galactorrhea were the adverse effects that were responsible for LAIR treatment cessation.

    Although muscle is considered to be the most important site for postprandial glucose disposal, the metabolic fate of oral glucose taken up by muscle remains unclear. We, therefore, employed the dual isotope technique (intravenous, [6-3H]-glucose; oral, [1-14C]glucose), indirect calorimetry, and forearm balance measurements of glucose, lactate, alanine, pyruvate, O2, and CO2 in nine normal volunteers to determine the relative importance of muscle glycogenic, glycolytic, and oxidative pathways ...

    The spatial arrangement of muscles in the oral suckers of six trematode species belonging to five families of the order Paramphistomatida is described. The functional load and adaptive significance of different muscle groups in the suckers themselves and the associated structures--preoral lip and muscular cap--are discussed. Complete section series in three projections have been examined; this demonstrates the presence of previously unnoticed structures, namely, semicircular and diagonal muscles, regulating shape of the oral cavity, and short longitudinal muscles, acting as a sphincter, as well as localization of the largest internal muscles on the sucker lateral sides. It has been shown that the presence of internal longitudinal muscles suggests that the organs in question are closer to the oral suckers of other trematodes rather than to their pharynxes.

    Full Text Available A 52-year-old insulin-dependant diabetic man presented to the Emergency Department 2 hours after a deliberate massive overdose of 2100 units of long-acting Levemir insulin and a large quantity of whisky. On initial assessment, his GCS was 3/15 and his capillary blood sugar was 2.6 mmol/L. The patient was given a 50 ml bolus of 50% dextrose, followed by intravenous infusions of both 5% and 10% dextrose. Despite the continuous infusions, he experienced 4 symptomatic hypoglycaemic episodes in the first 12 hours after admission. These were managed with oral glucose, IM glucagon, and further dextrose boluses. Blood electrolytes and pH were monitored throughout. Insulin overdoses are relatively common and often occur with an excess of other drugs or alcohol which can enhance its action. Overdoses can result in persistent hypoglycaemia, liver enzyme derangement, electrolyte abnormalities, and neurological damage. Overall mortality is 2.7% with prognosis poorest in patients who are admitted with decreased Glasgow Coma scale (GCS 12 hours after overdose.

    While a number of articles have reviewed the use of long-acting injectable antipsychotics (LAIs) in first-episode psychosis, there has been extremely limited focus on LAIs in children and adolescents. This review of the literature evaluated use of LAIs in children and youth under the age of 18. We conducted a comprehensive search of the PubMed, PsychINFO, CINAHL, and EMBASE databases using keywords related to LAIs, children, and psychiatric conditions, including schizophrenia, bipolar disorder, and schizoaffective disorder. Reports were included if they were in English, conducted between 1971 and 2015, and reported on use of LAIs in individuals less than the age of 18. The search identified seven reports including one open-label trial, three case reports, and three case series. No controlled trials were found. Sample sizes ranged from 1 to 19 with a total of 36 individuals in all cases combined. Mean sample age was 12.1 ± 2.2 in the open-label trial and calculated to be 14.9 ± 1.5 in the remainder of the reports. Most patients (80.6%) were boys. Primary diagnoses included bipolar I disorder (n = 18; 50%), schizophrenia (n = 7; 19.4%), and bipolar spectrum disorders (n = 6; 16.6%). The LAIs used were risperidone long-acting injection (n = 24; 66.7%), paliperidone palmitate (n = 8; 22.2%), fluphenazine decanoate (n = 1; 2.8%), aripiprazole extended-release injectable (n = 1; 2.8%), zuclopenthixol decanoate (n = 1; 2.8%), and olanzapine extended release (n = 1; 2.8%). Most cases reported clinical improvement and the majority of individuals (n = 14; 82.4%) were reported to tolerate the medication well. The most common side effects were weight gain (mean 5.7 ± 4.1 kg in the open-label trial), tremor (n = 2; 5.6%), and oculogyric crisis (n = 2; 5.6%). This literature review suggests that LAI use in youth with serious mental illness may improve clinical outcomes and adherence. Side effects of LAIs among

    Oral or topical daily administration of antiretroviral (ARV) drugs to HIV-1-negative individuals in vulnerable populations is a promising strategy for HIV-1 prevention. Adherence to the dosing regimen has emerged as a critical factor determining efficacy outcomes of clinical trials. Because adherence to therapy is inversely related to the dosing period, sustained release or long-acting ARV formulations hold significant promise for increasing the effectiveness of HIV-1 preexposure prophylaxis ...

    The provision of effective contraception is fundamental to the practice of women's health care. The most effective methods of reversible contraception are the so-called long-acting reversible contraceptives, intrauterine devices and implants. These methods have multiple advantages over other reversible methods. Most importantly, once in place, they do not require maintenance and their duration of action is long, ranging from 3 to 10 years. Despite the advantages of long-acting reversible contraceptive methods, they are infrequently used in the United States. Short-acting methods, specifically oral contraceptives and condoms, are by far the most commonly used reversible methods. A shift from the use of short-acting methods to long-acting reversible contraceptive methods could help reduce the high rate of unintended pregnancy in the United States. In this review of long-acting reversible contraceptive methods, we discuss the intrauterine devices and the contraceptive implant available in the United States, and we describe candidates for each method, noncontraceptive benefits, and management of complications.

    Risperidone long-acting injectable was previously approved for treatment of schizophrenia as biweekly injections in the gluteal muscle only. We present data on local injection-site tolerability and safety of risperidone long-acting injectable and comparability of systemic exposure of deltoid versus gluteal injections. Risperidone long-acting injectable was administered in an open-label, single-dose, two-way crossover study, with patients randomized to receive either 25mg gluteal/37.5mg deltoid crossover in two treatment periods or 50mg gluteal/50mg deltoid injections crossover; each treatment period was separated by an 85-day observation period (Study 1) and an open-label, multiple-dose study (4 sequential 37.5mg or 50mg deltoid injections every 2 weeks) (Study 2). The pharmacokinetic results from both the studies have already been published. In Study 1 (n=170), the majority of patients had no local injection-site findings, based on investigator and patient-rated evaluations. In Study 2 (n=53), seven of the 51 patients who received at least two deltoid injections discontinued (primary endpoint). However, none of the discontinuations were due to injection-site related reasons. The 90-percent upper confidence limit of the true proportion of injection-site issue withdrawals was 5.7 percent. No moderate or severe injection-site reactions were reported. Intramuscular injections via the deltoid and gluteal sites are equivalent routes of administration of risperidone long-acting injectable with respect to local injection-site tolerability. The overall safety and tolerability profile of risperidone long-acting injectable was comparable when administered as an intramuscular injection in the deltoid (37.5mg and 50mg) and gluteal (25mg and 50mg) sites.

    Objective The purpose of this study was to examine whether the diffusion tensor imaging (DTI) technique can be used as a modality to represent the structural deformation in the in vivo genioglossus (GG) muscle fibers with oral appliances (OAs). Study Design Three healthy subjects were recruited for the pilot study. A custom-made OA, which is modified from a tongue retaining device (TRD), was constructed for each subject before the DTI acquisitions. Recordings were made with and without OAs to compare the GG muscle fiber deformation. Result DTI provided good resolution of tongue muscle fibers in vivo and successful isolation of each muscle fiber bundle. In particular, the GG muscle fiber deformation due to OAs was clearly visualized. Conclusions This DTI technique may be used not only to identify the individual myoarchitecture, but also to assess muscle fiber deformations in vivo, such as constriction, dilatation, and rotation with OAs. Clinical studies for OSA patients will be the next step. PMID:19217012

    The advent of reversible long-acting contraceptives-IUDs, injectables and implants-has provided women throughout the world with valuable new fertility regulation options. These highly effective methods, together with male and female sterilization, have proven to be enormously popular and are now used by the majority of women and men who are currently contracepting worldwide. Despite their remarkable popularity, long-acting contraceptives have engendered considerable controversy. Political, ethical, and safety questions have emerged, stemming from the ways in which these contraceptives have been developed and used over the course of this century. At the heart of the concern is the issue of reproductive rights and freedom. This paper reviews the history of the development of long-acting contraceptives, including the prospect of new methods that will likely emerge from ongoing research and development. It also examines the history, in the United States and in developing countries, of the use and abuse of long-acting methods, including sterilization, in the context of eugenics and population control policies. It then describes a new paradigm of reproductive health and rights that has emerged from the International Conference on Population Development in Cairo, and which offers an enlightened approach to future policies and programs. In light of the wide variety of ways in which long-acting contraceptives have been provided, the paper examines the rights and responsibilities of governments, family planning providers, and individuals. An ethical framework for the use of long-acting methods is discussed, and public policies for the future are proposed.

    Fifty-nine chronic schizophrenic patients received one year of treatment with either fluphenazine enanthate or pipothiazine palmitate IM. Both long acting neuroleptics significantly decreased serum albumin, total protein and creatinine values. Triglycerides were decreased only early in treatment. Pretreatment findings from therapy responders, as compared with those who failed to respond to treatment, included higher albumin values and to a lesser extent, lower lactic dehydrogenase values and greater height. These results were discussed with an eye toward the hepatocellular effects of long acting phenothiazines and the effect of liver function on the pharmacokinetics of these medications.

    This paper proposes a remarkably facile staining protocol to visually investigate dynamic physiological events in insect tissues. We attempted to monitor Ca2+ dynamics during contraction of electrically stimulated living muscle. Advances in circuit miniaturization and insect neuromuscular physiology have enabled the hybridization of living insects and man-made electronic components, such as microcomputers, the result of which has been often referred as a Living Machine, Biohybrid, or Cyborg Insect. In order for Cyborg Insects to be of practical use, electrical stimulation parameters need to be optimized to induce desired muscle response (motor action) and minimize the damage in the muscle due to the electrical stimuli. Staining tissues and organs as well as measuring the dynamics of chemicals of interest in muscle should be conducted to quantitatively and systematically evaluate the effect of various stimulation parameters on the muscle response. However, existing staining processes require invasive surgery and/or arduous procedures using genetically encoded sensors. In this study, we developed a non-invasive and remarkably facile method for staining, in which chemical indicators can be orally administered (oral dosing). A chemical Ca2+ indicator was orally introduced into an insect of interest via food containing the chemical indicator and the indicator diffused from the insect digestion system to the target muscle tissue. We found that there was a positive relationship between the fluorescence intensity of the indicator and the frequency of electrical stimulation which indicates the orally dosed indicator successfully monitored Ca2+ dynamics in the muscle tissue. This oral dosing method has a potential to globally stain tissues including neurons, and investigating various physiological events in insects.

    The goal of this project was to prepare long-acting lanreotide acetate poly(lactic-co-glycolic acid) (PLGA) microspheres and to analyze the in vivo and in vitro release, safety and toxicology of these preparations. Long-acting lanreotide acetate PLGA microspheres that exhibited a 5-week slow-release period were prepared by a multiple-emulsion solvent evaporation method. Physical characterization, as well as the analysis of the in vivo and in vitro release, safety, acute toxicity and chronic toxicity of the lanreotide microspheres, were conducted in animal models in rats, guinea pigs, rabbits and beagle dogs. The lanreotide acetate PLGA microspheres prepared by multiple-emulsion solvent evaporation had smooth surfaces, uniform particle size and stable lanreotide loading. In vivo and in vitro experiments showed that the lanreotide acetate PLGA microspheres could continuously release lanreotide for 5 weeks. The safety of these long acting lanreotide microspheres was good in the following animal models: active systemic anaphylaxis test in guinea pigs, passive cutaneous anaphylaxis test in rats, hemolytic test in rabbits, local skin irritation test after subcutaneous administration in rabbits and muscle stimulation test in rabbits. Furthermore, no significant acute toxicity or chronic toxicity was observed after administration of lanreotide acetate PLGA microspheres in beagle dogs at dosages up to 22 mg/kg. The lanreotide acetate PLGA microspheres that were prepared in this study exhibited beneficial characteristics in apparent property and structural stability, as well as in release trends in vivo and in vitro.

    The mechanism by which cancer mediates muscle atrophy has been delineated in the past 3 decades and includes a prominent role of tumor-derived cytokines, such as IL-6, TNFα, and IL-1. These cytokines interact with their cognate receptors on muscle to activate the downstream transcription factor NF-κB and induce sarcomere proteolysis. Experimentally, inhibiting NF-κB signaling largely prevents cancer-induced muscle wasting, indicating its prominent role in muscle atrophy. Resveratrol, a natural phytoalexin found in the skin of grapes, has recently been shown to inhibit NF-κB in cancer cells, which led us to hypothesize that it might have a protective role in cancer cachexia. Therefore, we investigated whether daily oral resveratrol could protect against skeletal muscle loss and cardiac atrophy in an established mouse model. We demonstrate resveratrol inhibits skeletal muscle and cardiac atrophy induced by C26 adenocarcinoma tumors through its inhibition of NF-κB (p65) activity in skeletal muscle and heart. These studies demonstrate for the first time the utility of oral resveratrol therapy to provide clinical benefit in cancer-induced atrophy through the inhibition of NF-κB in muscle. These findings may have application in the treatment of diseases with parallel pathophysiologies such as muscular dystrophy and heart failure.

    Full Text Available Cigarette smoke exposure compromises health through damaging multiple physiological systems, including disrupting metabolic function. The purpose of this study was to determine the role of oral gingiva in mediating the deleterious metabolic effects of cigarette smoke exposure on skeletal muscle metabolic function. Using an in vitro conditioned medium cell model, skeletal muscle cells were incubated with medium from gingival cells treated with normal medium or medium containing suspended cigarette smoke extract (CSE. Following incubation of muscle cells with gingival cell conditioned medium, muscle cell mitochondrial respiration and insulin signaling and action were determined as an indication of overall muscle metabolic health. Skeletal muscle cells incubated with conditioned medium of CSE-treated gingival cells had a profound reduction in mitochondrial respiration and respiratory control. Furthermore, skeletal muscle cells had a greatly reduced response in insulin-stimulated Akt phosphorylation and glycogen synthesis. Altogether, these results provide a novel perspective on the mechanism whereby cigarette smoke affects systemic metabolic function. In conclusion, we found that oral gingival cells treated with CSE create an altered milieu that is sufficient to both disrupted skeletal muscle cell mitochondrial function and insulin sensitivity.

    The orexigenic peptide, ghrelin, is regulated by acute and chronic nutritional state. Although exogenously administered ghrelin stimulates pituitary GH secretion, little is known about the role of ghrelin in endogenous GH secretion or how high GH and IGF-I levels in acromegaly could affect ghrelin secretion and vice versa. Therefore, we evaluated fasting and post oral glucose tolerance test serum ghrelin levels in 19 patients with active acromegaly at baseline and after either surgery in 9 of these or administration of long-acting octreotide (Sandostatin LAR) in the other 10 patients. After surgical cure, fasting ghrelin rose from 312 +/- 56 pg/ml to 548 +/- 97 pg/ml (P = 0.013). Fasting serum ghrelin levels were higher in all patients after surgery and ranged between 112% and 349% of presurgery levels. Ghrelin levels fell significantly during long-acting octreotide therapy from 447 +/- 34 pg/ml to 206 +/- 15 pg/ml (P acromegaly; lowered serum levels of ghrelin in active acromegaly rise along with the postsurgery normalization of GH and IGF-I and improved insulin resistance. In contrast to surgical therapy, long-acting octreotide therapy persistently suppressed serum ghrelin levels. It remains to be determined whether altered circulating ghrelin concentrations could impact on body composition changes in acromegaly.

    Long-acting reversible contraceptives (LARCs) are safe for use in adolescents and do not rely on compliance or adherence for effectiveness. Continuation rates are higher and pregnancy rates are lower for adolescent users of LARCs compared with short-acting methods such as oral contraceptives. Similarly, repeat pregnancy rates are lower when LARCs are used compared with other forms of contraception. Myths and misconceptions about LARCs and other contraceptives remain a barrier to their use. Health care providers are in a unique position to provide confidential care to adolescents, and should provide education to them about the various contraceptive options, especially LARCs.

    The perforated pharynx has generally been regarded as a shared characteristic of chordates. However, there still remains phylogenetic ambiguity between the cilia-driven system in invertebrate chordates and the muscle-driven system in vertebrates. Giant larvae of the genus Asymmetron were reported to develop an orobranchial musculature similar to that of vertebrates more than 100 years ago. This discovery might represent an evolutionary link for the chordate branchial system, but few investigations of the lancelet orobranchial musculature have been completed since. We studied staged larvae of a Japanese population of Branchiostoma japonicum to characterize the developmental property of the orobranchial musculature. The larval mouth and the unpaired primary gills develop well-organized muscles. These muscles function only as obturators of the openings without antagonistic system. As the larval mouth enlarged posteriorly to the level of the ninth myomere, the oral musculature was fortified accordingly without segmental patterning. In contrast, the iterated branchial muscles coincided with the dorsal myomeric pattern before metamorphosis, but the pharynx was remodeled dynamically irrespective of the myomeric pattern during metamorphosis. The orobranchial musculature disappeared completely during metamorphosis, and adult muscles in the oral hood and velum, as well as on the pterygial coeloms developed independently. The lancelet orobranchial musculature is apparently a larval adaptation to prevent harmful intake. However, vestigial muscles appeared transiently with the secondary gill formation suggest a bilateral ancestral state of muscular gills, and a segmental pattern of developing branchial muscles without neural crest and placodal contributions is suggestive of a precursor of vertebrate branchiomeric pattern.

    Full Text Available Since airflow obstruction in chronic obstructive pulmonary disease (COPD is to some extent reversible, bronchodilators play an important role in the maintenance treatment of COPD the more they reduce hyperinflation and, as a result, improve dyspnoea and exercise capacity. Since parasympathetic activity is the dominant reversible component of airflow obstruction in COPD, inhaled short-acting anticholinergic agents (SAAC, in particular ipratropium, became an efficient and safe first-line treatment, especially when combined with a short-acting beta2-adrenergic receptor agonist. Even better results were obtained when combining the SAAC ipratropium to a long-acting beta2-adrenergic receptor agonist (LABA, once they became available. Recently, tiotropium bromide, the first of a new class of selective and long-acting anticholinergic agents was introduced for once-daily maintenance treatment of COPD patients. Several large long-term randomised clinical trials comparing tiotropium to placebo as well as to the SAAC ipratropium and the LABA salmeterol, have confirmed the long-acting and superior bronchodilator effect of tiotropium without any evidence of drug tolerance developing. These studies also have clearly demonstrated that tiotropium positively affects several other important health outcomes, such as dyspnoea sensation, exercise capacity, utilisation of rescue bronchodilators, health-related quality of life, COPD exacerbations and hospitalisations because of exacerbations. The improvement in these real-life outcomes appears related to the reduction in both static and dynamic hyperinflation. In all these studies, tiotropium was well tolerated and safe; the only relevant side-effect encountered being dry mouth, usually mild and often transitory. Finally, it has been shown that the combination of tiotropium with a LABA affords superior bronchodilatation than both agents alone, indicating that both classes of long-acting bronchodilators should be

    Growth hormone (GH) treatment has been an established therapy for GH deficiency (GHD) in children and adults for more than three decades. Numerous studies have shown that GH treatment improves height, body composition, bone density, cardiovascular risk factors, physical fitness and quality of life and that the treatment has few side effects. Initially GH was given as intramuscular injections three times per week, but daily subcutaneous injections were shown to be more effective and less inconvenient and the daily administration has been used since its introduction in the 1980s. However, despite ongoing improvements in injection device design, daily subcutaneous injections remain inconvenient, painful and distressing for many patients, leading to noncompliance, reduced efficacy and increased health care costs. To address these issues a variety of long-acting formulations of GH have been developed. In this review we present the current status of long-acting GH preparations and discuss the specific issues related to their development.

    Full Text Available Michael K RainerMemory-Clinic and Psychiatric Department, Donauspital, Vienna, AustriaAbstract: A long-acting form of the second-generation antipsychotic drug risperidone is now broadly available for the treatment of schizophrenia and closely related psychiatric conditions. It combines the advantage of previously available depot formulations for first-generation drugs with the favorable characteristics of the modern “atypical” antipsychotics, namely higher efficacy in the treatment of the negative symptoms of schizophrenia and reduced motor disturbances. Published clinical studies show an objective clinical efficacy (as per psychiatric symptom scores and relapse data that exceeds that of oral atypical antipsychotics when patients are switched to the long-acting injectable form, a low incidence of treatment-emergent extrapyramidal side effects, and very good acceptance by patients. Available data for maintenance treatment of bipolar disorder show equivalence with the oral form instead of superiority, but are still limited. As it seems likely that efficacy benefits are mostly due to the fact that the injectable form reduces the demand for patient compliance to one physician visit every 2 weeks instead of self-administration on a daily or twice-daily basis, additional potential could exist in other psychiatric disorders where atypical antipsychotic drugs are of benefit but where patient adherence to treatment schedules is typically low.Keywords: risperidone, schizophrenia, psychotic disorders, patient compliance; delayed-action preparations, injections, intramuscular

    Dysphagia is reported in advanced stages of Duchenne muscular dystrophy (DMD). The population of DMD is changing due to an increasing survival. We aimed to describe the dysphagia in consecutive stages and to assess the underlying mechanisms of dysphagia in DMD, in order to develop mechanism based recommendations for safe swallowing. In this cross-sectional study, participants were divided into: early and late ambulatory stage (AS, n = 6), early non-ambulatory stage (ENAS, n = 7), and late non-ambulatory stage (LNAS, n = 11). Quantitative oral muscle ultrasound was performed to quantify echo intensity. Swallowing was assessed with a video fluoroscopic swallow study, surface electromyography (sEMG) of the submental muscle group and tongue pressure. Differences in outcome parameters among the three DMD stages were tested with analysis of variance. Oral muscles related to swallowing were progressively affected, starting in the AS with the geniohyoid muscle. Tongue (pseudo) hypertrophy was found in 70 % of patients in the ENAS and LNAS. Oral phase problems and post-swallow residue were observed, mostly in the LNAS with solid food. sEMG and tongue pressure data of swallowing solid food revealed the lowest sEMG amplitude, the longest duration and lowest tongue pressure in the LNAS. In case of swallowing problems in DMD, based on the disturbed mechanisms of swallowing, it is suggested to (1) adjust meals in terms of less solid food, and (2) drink water after meals to clear the oropharyngeal area.

    Schizoaffective disorder (SCA) is a chronic and disabling mental illness that presents with mixed symptoms of schizophrenia and affective disorders. SCA is recognized as a discrete disorder, but with greater heterogeneity and symptom overlap, leading to difficulty and delay in diagnosis. Although the overall prognosis is intermediate between schizophrenia and mood disorders, SCA is associated with higher rates of suicide and hospitalization than schizophrenia. No treatment guidelines exist for SCA, and treatment is frequently complex, involving off-label use and polypharmacy (typically combinations of antipsychotics, mood stabilizers, and antidepressants). Oral paliperidone extended-release was the first agent to be approved for the treatment of SCA. As in schizophrenia and bipolar disorder, adherence to oral medications is poor, further contributing to suboptimal outcomes. The use of an antipsychotic in a long-acting injection (LAI) addresses adherence issues, thus potentially reducing relapse. Paliperidone palmitate represents the LAI formulation of paliperidone. In a long-term, double-blind, randomized, controlled trial of adult patients (n=334; intent-to-treat [ITT]) with SCA, paliperidone long-acting injection (PLAI) significantly delayed risk of relapse compared to placebo (hazard ratio 2.49, 95% confidence interval, 1.55-3.99; PPLAI when used as either monotherapy or adjunctive therapy for the maintenance treatment of SCA. The results are consistent with a similarly designed study conducted in patients with schizophrenia, which suggests a benefit in the long-term control of not only psychotic but also affective symptoms. No new safety signals were observed. When used in monotherapy, PLAI simplifies treatment by reducing complex pharmacotherapy and obviating the necessity for daily oral medications. PLAI is the second agent, and the first LAI, to be approved for the treatment of SCA; as an LAI formulation, there is the advantage of improved adherence and

    Herpes simplex virus type 1 is one of the most frequent causes of oral infection in humans, especially during early childhood. Several experimental models have been developed to study the pathogenesis of this virus but all of them employed adult animals. In this work, we developed an experimental model that uses mice younger than 4 days old, to more closely resemble human infection. Mice were infected subcutaneously with the prototype strain McIntyre of Herpes simplex-1, and the progression of infection was studied by immunoperoxidase. All animals died within 24-72 h post-infection, while viral antigens were found in the oral epithelium, nerves and brain. The most striking result was the finding of viral antigens in the nucleus and cytoplasm of cells belonging to striated muscles. Organotypic cultures of striated muscles were performed, and viral replication was observed in them by immunocytochemistry, electron microscopy and viral isolation. We conclude that the infection of striated muscles is present from the onset of oral infection and, eventually, could explain some clinical observations in humans.

    Intravenous regional anesthesia is a widely used technique for brief surgical interventions, primarily on the upper limbs and less frequently, on the lower limbs. It began being used at the beginning of the 20th century, when Bier injected procaine as a local anesthetic. The technique to accomplish anesthesia has not changed much since then, although different drugs, particularly long-acting local anesthetics, such as ropivacaine and levobupivacaine in low concentrations, were introduced. Additionally, drugs like opioids, muscle relaxants, paracetamol, neostigmine, magnesium, ketamine, clonidine, and ketorolac, have all been investigated as adjuncts to intravenous regional anesthesia, and were found to be fairly useful in terms of an increased onset of operative anesthesia and longer lasting perioperative analgesia. The present article provides an overview of current knowledge with emphasis on long-acting local anesthetic drugs.

    Full Text Available Long-acting β2-adrenergic receptor agonists (LABA, a class of agents for the long-term management of childhood bronchial asthma, are recommended for use in combination with steroid inhalation for the treatment of the morning dip in severe childhood asthma. In the present review, salmeterol (SM, a LABA inhalant with a long-acting bronchodilator effect, was compared with the recently introduced tulobuterol patch (TBP in terms of safety and efficacy, based on their respective clinical effects on childhood asthma. From a clinical perspective, both drugs had a preventive effect by suppressing the morning dip and exercise-induced asthma when used concomitantly with an inhaled corticosteroid, and both agents were associated with a lower incidence of adverse effects on the cardiovascular system than oral β2-adrenergic receptor agonists. Based on these findings, both SM and TBP are concluded to be highly efficacious and safe bronchodilator agents that are appropriate for the long-term management of childhood asthma.

    Background 18F-fluoro-2-deoxy-D-glucose (18F-FDG) accumulations are commonly seen in the neck-related muscles of the surgical and non-surgical sides after surgery with neck dissection (ND) for oral cancers, which leads to radiologists having difficulty in diagnosing the lesions. To examine the alterations in 18F-FDG accumulation in neck-related muscles of patients after ND for oral cancer. Material and Methods 18F-FDG accumulations on positron emission tomography (PET)-computed tomography (CT) in neck-related muscles were retrospectively analyzed after surgical dissection of cervical lymph nodes in oral cancers. Results According to the extent of ND of cervical lymph nodes, the rate of patients with 18F-FDG-PET-positive areas increased in the trapezius, sternocleidomastoid, and posterior neck muscles of the surgical and/or non-surgical sides. In addition, SUVmax of 18F-FDG-PET-positive areas in the trapezius and sternocleidomastoid muscles were increased according to the extent of the ND. Conclusions In evaluating 18F-FDG accumulations after ND for oral cancers, we should pay attention to the 18F-FDG distributions in neck-related muscles including the non-surgical side as false-positive findings. Key words:18F-FDG, PET-CT, oral cancers, muscles. PMID:27031062

    This study investigated the potential mechanisms by which oral supplementation of N-carbamylglutamate (NCG), an analogue of endogenous N-acetylglutamate (an activator of arginine synthesis) increases growth rate in sow-reared piglets. Two piglets of equal body weight (BW) and of the same gender from each lactating sow were allotted to receive oral administration of 0 (control) or 50 mg of NCG/kg BW every 12 h for 7 d. Piglets (n=32; BW=3 kg) were studied in the food-deprived or fed state following the 7 d of treatment. Overnight food-deprived piglets were given NCG or water (control) at time 0 and 60 min. Piglets studied in the fed state were gavage-fed sow's milk with their respective NCG treatment at 0 and 60 min. At 60 min, the piglets were administered a flooding dose of [3H]phenylalanine and killed at 90 min to measure tissue protein synthesis. Piglets treated with NCG gained 28% more weight than control pigs (P<0.001) over the 7-d period. Fed pigs had greater rates of protein synthesis in longissimus dorsi and gastrocnemius muscles and duodenum compared with food-deprived pigs (P<0.001). Absolute protein synthesis rates in longissimus dorsi (P=0.050) and gastrocnemius (P=0.068) muscles were 30 and 21% greater, respectively, in NCG-treated compared with control pigs. Piglets supplemented with NCG also had greater plasma concentrations of arginine and somatotropin than control pigs (P<0.001). The results suggest that oral NCG supplementation increases plasma arginine and somatotropin levels, leading to an increase in growth rate and muscle protein synthesis in nursing piglets.

    The number of long-acting injectable antipsychotics (LAIA) has increased in recent years. The safety and efficacy of that treatment are not established in children. This study aims to address this gap of information by studying such treatments in a case series. This retrospective chart review of patients identified by the investigators at an academic acute inpatient psychiatric unit included all patients from the past 24 months who required new initial treatment with LAIA. This study included a case series of the nine patients along with Clinical Global Impression-Severity (CGI-S) scores from admission and discharge and Clinical Global Impression-Improvement (CGI-I) scores. Other observations included the presentation of primary psychiatric diagnosis, psychiatric and medical comorbidities, age, sex, previous and LAIA psychiatric medications, reasoning for LAIA treatment, adverse events, CGI-S and CGI-I scores, and outpatient resources utilized to continue treatment. The case series included two females and seven males within the ages of 14-17 years. Of those patients, five were treated with paliperidone palmitate, one treated with risperidone, one treated with fluphenazine, and one treated with aripiprazole. Primary psychiatric diagnosis of the patients in the case series included five with schizophrenia, one with schizoaffective disorder, one with bipolar affective disorder-type I, one with bipolar affective disorder-not otherwise specified, and one with mood disorder-not otherwise specified. In all nine cases, noncompliance was a consideration in treatment with LAIA. Frequent running away and severity of illness were also considerations in one case each. All of the patients required community resources with injectable services. This study describes initiation of treatment with LAIA in 14-17-year olds in an acute inpatient psychiatric unit with serious mental illness. This study also demonstrates the need for outpatient community resources with the ability to

    Myasthenia gravis is an autoimmune disease characterized by muscle weakness due to autoantibodies affecting the neuromuscular junction. Co-occurrence of myasthenia gravis and schizophrenia is very rare and raises a challenge in management of both diseases. Antipsychotic drugs exhibit anticholinergic side effects and have the potentials of worsening myasthenia. Long-acting risperidone is an injectable atypical antipsychotic drug that has not been previously reported to worsen myasthenia gravis in literature. We report the first case report of worsening of myasthenia after receiving long-acting risperidone injection for schizophrenia in a 29-year-old female with both diseases. She started to have worsening 2 weeks following the first injection and her symptoms persisted despite receiving plasma exchange. This could be explained by the pharmacokinetics of the drug. We recommend that long-acting risperidone should be used with caution in patients with myasthenia gravis, and clinicians must be aware of the potential risks of this therapy.

    Several mechanisms, such as innate immune responses via Toll-like receptor-4, accumulation of diacylglycerols (DAG)/ceramides, and activation of protein kinase C (PKC), are considered to underlie skeletal muscle insulin resistance. In this study, we examined initial events occurring during the onset of insulin resistance upon oral high-fat loading compared with lipid and low-dose endotoxin infusion. Sixteen lean insulin-sensitive volunteers received intravenous fat (iv fat), oral fat (po fat), intravenous endotoxin (lipopolysaccharide [LPS]), and intravenous glycerol as control. After 6 h, whole-body insulin sensitivity was reduced by iv fat, po fat, and LPS to 60, 67, and 48%, respectively (all P < 0.01), which was due to decreased nonoxidative glucose utilization, while hepatic insulin sensitivity was unaffected. Muscle PKCθ activation increased by 50% after iv and po fat, membrane Di-C18:2 DAG species doubled after iv fat and correlated with PKCθ activation after po fat, whereas ceramides were unchanged. Only after LPS, circulating inflammatory markers (tumor necrosis factor-α, interleukin-6, and interleukin-1 receptor antagonist), their mRNA expression in subcutaneous adipose tissue, and circulating cortisol were elevated. Po fat ingestion rapidly induces insulin resistance by reducing nonoxidative glucose disposal, which associates with PKCθ activation and a rise in distinct myocellular membrane DAG, while endotoxin-induced insulin resistance is exclusively associated with stimulation of inflammatory pathways.

    The purpose of this study was to examine how submucosal injection of a clinically relevant dose of a lidocaine hydrochloride solution containing epinephrine affects the muscle relaxant effects of rocuronium bromide. Sixteen patients scheduled for orthognathic surgery participated in this study. All patients were induced with fentanyl citrate, a target-controlled infusion of propofol and rocuronium bromide. Anesthesia was maintained by total intravenous anesthesia. After nasotracheal intubation, an infusion of rocuronium bromide was started at 7 µg/kg/min, and the infusion rate was then adjusted to maintain a train of four (TOF) ratio at 10 to 15%. The TOF ratio just prior to oral mucosal injection of a 1% lidocaine hydrochloride solution containing 10 µg/mL epinephrine (LE) was taken as the baseline. TOF ratio was observed for 20 minutes, with 1-minute intervals following the start of injection. Mean epinephrine dose was 85.6 ± 18.6 µg and mean infusion rate of rocuronium bromide was 6.3 ± 1.6 µg/kg/min. TOF ratio began to decrease 2 minutes after the injection of LE, reached the minimum value at 3.1 ± 3.6% 12 minutes after the injection, and then began to recover. We conclude that oral mucosal injection of LE enhances the muscle relaxant effects of rocuronium bromide.

    The purpose of this study was to identify clinician characteristics associated with higher prescription rates of long-acting injectable (LAI) antipsychotics, as well as the sources that influence medical decision-making regarding the treatment of schizophrenia. We surveyed 202 psychiatrists during six regional French conferences (Bordeaux, Lyon, Marseille, Nice, Paris, and Strasbourg). Data on the characteristics of practice, prescription rates of antipsychotic, and information sources about their clinical decisions were collected. Most psychiatrists used second-generation antipsychotics (SGAs), and preferentially an oral formulation, in the treatment of schizophrenia. LAI SGAs were prescribed to 30.4% of schizophrenic patients. The duration and type of practice did not influence the class or formulation of antipsychotics used. The clinicians following the higher percentage of schizophrenic patients were associated with a higher use of LAI antipsychotics and a lower use of oral SGAs. Personal experience, government regulatory approval, and guidelines for the treatment of schizophrenia were the three main contributing factors guiding clinicians' decision-making regarding the treatment of schizophrenia. The more clinicians follow schizophrenic patients, the more they use LAI antipsychotics. The development of specialized programs with top specialists should lead to better use of LAI antipsychotics in the treatment of schizophrenia.

    INTRODUCTION: GH induces acute insulin resistance in skeletal muscle in vivo, which in rodent models has been attributed to crosstalk between GH and insulin signaling pathways. Our objective was to characterize time course changes in signaling pathways for GH and insulin in human skeletal muscle in vivo following GH exposure in the presence and absence of an oral glucose load. METHODS: Eight young men were studied in a single-blinded randomized crossover design on 3 occasions: 1) after an int...

    To understand the most important steps required to implement immediate postpartum long-acting reversible contraception (LARC) programs in different Georgia hospitals and the barriers to implementing such a program. This was a qualitative study. We interviewed 32 key personnel from 10 Georgia hospitals working to establish immediate postpartum LARC programs. Data were analyzed using directed qualitative content analysis principles. We used the Stages of Implementation to organize participant-identified key steps for immediate postpartum LARC into an implementation guide. We compared this guide to hospitals' implementation experiences. At the completion of the study, LARC was available for immediate postpartum placement at 7 of 10 study hospitals. Participants identified common themes for the implementation experience: team member identification and ongoing communication, payer preparedness challenges, interdependent department-specific tasks, and piloting with continuing improvements. Participants expressed a need for anticipatory guidance throughout the process. Key first steps to immediate postpartum LARC program implementation were identifying project champions, creating an implementation team that included all relevant departments, obtaining financial reassurance, and ensuring hospital administration awareness of the project. Potential barriers included lack of knowledge about immediate postpartum LARC, financial concerns, and competing clinical and administrative priorities. Hospitals that were successful at implementing immediate postpartum LARC programs did so by prioritizing clear communication and multidisciplinary teamwork. Although the implementation guide reflects a comprehensive assessment of the steps to implementing immediate postpartum LARC programs, not all hospitals required every step to succeed. Hospital teams report that implementing immediate postpartum LARC programs involves multiple departments and a number of important steps to consider. A

Second-generation antipsychotic LAIs (SGA-LAIs combine the advantages of SGA with a long-acting formulation. The purpose of this review is to evaluate the available literature concerning the impact of SGA-LAIs on patient functioning and quality of life (QOL. Although several studies regarding schizophrenia patients’ functioning and QOL have been performed, the quantity of available data still varies greatly depending on the SGA-LAI under investigation. After reviewing the literature, it seems that SGA-LAIs are effective in ameliorating patient functioning and/or QOL of patients with schizophrenia, as compared with placebo. However, while methodological design controversy exists regarding the superiority of risperidone LAI versus oral antipsychotics, the significant amount of evidence in recently published research demonstrates the beneficial influence of risperidone LAI on patient functioning and QOL in stable patients and no benefit over oral treatment in unstable patients. However, the status of the research on SGA-LAIs is lacking in several aspects that may help physicians in choosing the correct drug therapy. Meaningful differences have been observed between SGA-LAIs in the onset of their clinical efficacy and in the relationships between symptoms and functioning scores. Moreover, head-to-head studies comparing the effects of SGA-LAIs on classical measures of psychopathology and functioning are available mainly on risperidone LAI, while those comparing olanzapine LAI with other

    5'-AMP-activated protein kinase (AMPK) has been suggested to be a 'metabolic master switch' regulating various aspects of muscle glucose and fat metabolism. In isolated rat skeletal muscle, glucose suppresses the activity of AMPK and in human muscle glycogen loading decreases exercise-induced AMPK...... activation. We hypothesized that oral glucose ingestion during exercise would attenuate muscle AMPK activation. Nine male subjects performed two bouts of one-legged knee-extensor exercise at 60% of maximal workload. The subjects were randomly assigned to either consume a glucose containing drink or a placebo...... drink during the two trials. Muscle biopsies were taken from the vastus lateralis before and after 2 h of exercise. Plasma glucose was higher (6.0 +/- 0.2 vs. 4.9 +/- 0.1 mmol L-1, P

    Deaf individuals show a number of difficulties related to the functionality of the stomatognathic system, mainly by reason of the little or no use of facial musculature during speech either due to the use of sign language or to the difficulty that these individuals have in articulating words. The stomatognathic system muscles play important roles in functions such as mastication, deglutition, and phonation. This study aimed to assess, by means of computerized bilateral electromyography (EMG), masseter and temporal muscles of 12 oralized deaf individuals in clinical activities that involve part of this masticatory musculature and compare this system's functionality with that of 12 normal listening individuals, performing the same activities. An 8-channel K6-I EMG Light Channel Surface Electromyography device was used (Myo-Tronics Co.Seattle, WA, USA), in addition to disposable double electrodes covered with silver chloride (Duotrodes; Myo-tronics Co., Seattle, WA) containing a conductor gel (Myogel- Myo-tronics Co., Seatlle, WA). The averaged rectified EMG values were normalized with reference to the EMG amplitude induced by a maximum bite force. The statistical analysis confirmed that there were any significant differences between the groups, clinical activities, and muscles, and also effects of interaction among them. The analysis made use of Variance Analysis (ANOVA). Significant differences (p masseter and temporal muscular activity such as mastication, mouth opening and closing, and dental compression. Greater electromyographic values were found for both deaf individuals and healthy controls during clinical activities of mastication and dental compression. Based on the obtained data, we concluded that deaf individuals showed a lower activity of the masticatory musculature than healthy individuals; the differences were significant at the level of p < 0.01 between the performed clinical activities; and all deaf individuals and healthy controls showed greater

    Treatment adherence is a significant problem in patients with bipolar disorder. This study was designed to determine the efficacy of risperidone long-acting injectable (LAI) in the maintenance treatment of bipolar I disorder. Eligible patients with current or recent manic or mixed episodes (n = 559, aged 18-65 years) were treated with open-label oral risperidone for 3 weeks (period II) and open-label risperidone LAI for 26 weeks (n = 501; period III). Patients who maintained response (n = 303) were randomly allocated 1:1 to placebo injections (n = 149) or to continue risperidone LAI (n = 154) for up to 24 months (period IV). Most (77%) patients on risperidone LAI received a dose of 25 mg every 2 weeks during period IV. Time to recurrence for any mood episode (primary outcome variable) was significantly longer in the risperidone LAI group versus placebo (p or = 7% (compared with the period's baseline) occurred in 15% of patients in period III; in 12% of patients on risperidone LAI and 3% of patients on placebo in period IV. Risperidone LAI monotherapy significantly delayed the time to recurrence of mood episodes, versus placebo, in this controlled, randomized study in patients with bipolar I disorder. Risperidone LAI was tolerable and no new safety concerns emerged compared with previous studies of risperidone LAI. Copyright 2010 Society of Biological Psychiatry. Published by Elsevier Inc.

Even with treatment, the majority of patients relapse within 5 years, and suicide may occur in up to 10% of patients. Poor adherence to oral antipsychotics is the most common cause of relapse. The discontinuation rate for oral antipsychotics in schizophrenia ranges from 26% to 44%, and as many as two-thirds of patients are at least partially nonadherent, resulting in increased risk of hospitalization. A very helpful approach to improve adherence in schizophrenia is the use of long-acting injectable (LAI antipsychotics, although only a minority of patients receive these. Reasons for underutilization may include negative attitudes, perceptions, and beliefs of both patients and health care professionals. Research shows, however, significant improvements in adherence with LAIs compared with oral drugs, and this is accompanied by lower rates of discontinuation, relapse, and hospitalization. In addition, LAIs are associated with better functioning, quality of life, and patient satisfaction. A need exists to encourage broader LAI use, especially among patients with a history of nonadherence with oral antipsychotics. This paper reviews the impact of nonadherence with antipsychotic drug therapy overall, as well as specific outcomes of the schizophrenia patient, and highlights the potential benefits of LAIs.

    Full Text Available Approximately 80% of patients with the first-episode schizophrenia reach symptomatic remission after antipsychotic therapy. However, within two years most of them relapse, mainly due to low levels of insight into the illness and nonadherence to their oral medication. Therefore, although the formal data available is limited, many experts recommend prescribing long-acting injectable second-generation antipsychotics (mostly risperidone or alternatively paliperidone in the early stages of schizophrenia, particularly in patients who have benefited from the original oral molecule in the past and agree to receive long-term injectable treatment. Early application of long-acting injectable second-generation antipsychotics can significantly reduce the risk of relapse in the future and thus improve not only the social and working potential of patients with schizophrenia but also their quality of life.

    Treatment of severe diffuse congenital hyperinsulinism (CHI) without sufficient response to diazoxide is complicated by the lack of approved drugs. Therefore, patients are often hospitalized long-term or have to undergo pancreatic surgery if episodes of severe hypoglycaemia cannot be prevented. A long-acting somatostatin analogue, octreotide, has been reported to be an effective treatment option that prevents severe hypoglycaemia in children with CHI, and its off-label use is common in CHI. However, octreotide requires continuous i.v. or s.c. infusion or multiple daily injections. Here, we report our experiences with the use of a monthly application of a long-acting somatostatin analogue, lanreotide autogel® (LAN-ATG), in early infancy. The mean blood glucose concentration within 7 days before the first LAN-ATG administration were compared to 7 days after the first LAN-ATG administration and increased by 0.75 mmol/L (range 0.39-1.19 mmol/L). In the following weeks intravenous glucose infusions, octreotide, and glucagon treatment could be successfully stopped in all patients 3-20 days after the first LAN-ATG injection without substantial worsening of the hypoglycaemia rate. Increased carbohydrate requirements could be normalized with an average reduction in the carbohydrate-intake of 7 g/kg body weight/d (range 1.75-12.8 g/kg body weight/d). Over a total of 52 treatment months, no serious adverse effects occurred. Long-term LAN-ATG treatment improved blood glucose concentrations, lowered the frequency of hypoglycaemia or allowed for normalization of oral carbohydrate intake in infants with CHI younger than 6 months of age. No severe side effects were observed. LAN-ATG might be an alternative treatment option in infants with severe CHI who lack risk factors for necrotizing enterocolitis and are not responding to current treatment regimens as an alternative to surgery after careful individual evaluation.

    Oral or topical daily administration of antiretroviral (ARV) drugs to HIV-1-negative individuals in vulnerable populations is a promising strategy for HIV-1 prevention. Adherence to the dosing regimen has emerged as a critical factor determining efficacy outcomes of clinical trials. Because adherence to therapy is inversely related to the dosing period, sustained release or long-acting ARV formulations hold significant promise for increasing the effectiveness of HIV-1 preexposure prophylaxis (PrEP) by reducing dosing frequency. A novel, subdermal implant delivering the potent prodrug tenofovir alafenamide (TAF) with controlled, sustained, zero-order (linear) release characteristics is described. A candidate device delivering TAF at 0.92 mg day(-1) in vitro was evaluated in beagle dogs over 40 days for pharmacokinetics and preliminary safety. No adverse events related to treatment with the test article were noted during the course of the study, and no significant, unusual abnormalities were observed. The implant maintained a low systemic exposure to TAF (median, 0.85 ng ml(-1); interquartile range [IQR], 0.60 to 1.50 ng ml(-1)) and tenofovir (TFV; median, 15.0 ng ml(-1); IQR, 8.8 to 23.3 ng ml(-1)), the product of in vivo TAF hydrolysis. High concentrations (median, 512 fmol/10(6) cells over the first 35 days) of the pharmacologically active metabolite, TFV diphosphate, were observed in peripheral blood mononuclear cells at levels over 30 times higher than those associated with HIV-1 PrEP efficacy in humans. Our report on the first sustained-release nucleoside reverse transcriptase inhibitor (NRTI) for systemic delivery demonstrates a successful proof of principle and holds significant promise as a candidate for HIV-1 prophylaxis in vulnerable populations.

    Based on its ideal PK/PD ratios, doxycycline hyclate (DOX-h), a time-dependant antibacterial, is ideally expected to achieve sustained plasma drug concentrations at or slightly above the MIC level for as long as possible between dosing intervals. Pursuing this end, a poloxamer-based matrix was used to produce a 10% long-acting injectable preparation (DOX-h-LA) and its serum concentrations vs. time profile investigated after its injection to pigs in the pericaudal s.c. by parallel design. Results were compared with the forced oral bolus dose and i.v. pharmacokinetics of DOX-h. For this study, 12 recently weaned pigs per group were included in this trial, and a dose of 20 mg/kg was injected in all cases. DOX-h-LA showed the greatest values for bioavailability (115.38%); maximum serum concentration (Cmax) value was 1.5 ± 0.2 with a time to reach Cmax of 3.41 ± 0.04 h and an elimination rate constant of 70.93 ± 0.87( ) h. Considering minimum effective serum concentration of 0.5 μg/mL, a dose interval of at least 5 days can be achieved for DOX-h-LA, whereas p.o. and i.v. dosing of DOX-h may only last 11 and 15 h, respectively. Pigs were slaughtered on day 30 after this trial, and no visible remnants of the preparation were detected neither fibrosis was observed after a thorough macroscopic and histopathological analysis.

    Adolescents are at high risk for unintended pregnancy. Because of pediatricians' potential role in contraceptive counseling, understanding their attitudes and beliefs and counseling practices about use of long-acting reversible contraceptives (LARC; ie, etonogestrel implant and intrauterine devices [IUDs]) is vital. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We interviewed primary care pediatricians (N = 23) in a Midwestern city in June-August 2014. We transcribed the interviews, developed a coding schema, and analyzed these qualitative data using a priori and open coding of transcripts. Few pediatricians had favorable views on adolescent IUD use and most did not include IUDs in routine contraception counseling. Pediatricians perceived IUDs to impose significant risks for adverse reproductive outcomes and to be poorly tolerated by adolescents. Poor and/or outdated knowledge influenced inaccurate beliefs and unsupportive attitudes. Whereas some pediatricians were advocates for adolescent use of IUDs, many others had concerns that IUDs were not appropriate and not favored by adolescents. In contrast, participants viewed the etonogestrel implant more favorably and often included it in routine counseling. Some pediatricians focused on the familiar and readily available methods (injectable and oral contraceptives) or assumed patients had predetermined expectations for those methods. Time spent counseling on LARC was also perceived as a barrier. Pediatricians described how education and increased familiarity with LARC changed viewpoints. A variety of beliefs and attitudes, as well as factors such as time and personal habits, influence pediatricians' contraceptive counseling practices. Until knowledge deficits are addressed, uninformed viewpoints and unfavorable attitudes will limit adolescents' access to LARC, especially IUDs.

    A recent meta-analysis showed that long-acting injectable (LAI) antipsychotics were not superior to oral antipsychotics for preventing relapse in patients with schizophrenia. We therefore designed a treatment strategy combining risperidone LAI and COMPASS (COMprehensive Psycho-educational Approach and Scheme Set), an original psychoeducational program supporting treatment with risperidone LAI and evaluating subjective treatment satisfaction, transition of symptoms, and effectiveness in preventing symptomatic relapse. The aim of this study was to examine whether addition of COMPASS to risperidone LAI was more effective in preventing relapse in schizophrenia patients than risperidone LAI alone, with the latter group consisting of patients enrolled in a Phase III trial of risperidone LAI in Japan. Patients were followed up for 6 months, with COMPASS continuously implemented from the transition to the observation phase. The primary efficacy measurements were relapse rate (rates of rehospitalization and discontinuation due to inefficacy). Secondary efficacy measurements were the Brief Psychiatric Rating Scale (BPRS) and Global Assessment of Functioning (GAF) scores. Of the 96 patients originally enrolled, 19 (19.8%) were discontinued from all causes. During the 6-month study period, ten of the 96 patients (10.4%) relapsed, compared with a 12.2% relapse rate in patients enrolled in a Phase III trial of risperidone LAI in Japan. Patients showed significant improvements in BPRS total scores (P = 0.0031), BPRS positive (P = 0.0451), BRPS negative (P < 0.0001), and general subscale scores (P = 0.0031), and GAF (P < 0.0001) from baseline to 6 months. In conclusion, the lower relapse rate observed in patients treated with COMPASS plus risperidone LAI than in patients treated with risperidone LAI alone suggests that COMPASS may have benefits in the treatment of schizophrenia, indicating a need for randomized, controlled trials in larger numbers of patients.

Méthode : Une recherche des bases de données médicales a été menée dans la littérature publiée (1995–2012) sur les effets des IAP sur les domaines de la rémission, l’observance, la rechute, et l’hospitalisation. Les résultats obtenus des essais randomisés contrôlés (ERC), des revues systématiques, des méta-analyses, et des études d’observation à grande échelle ont été inclus. Les données de consensus des experts ont aussi été sollicitées en ce qui concerne l’utilisation des IAP dans un contexte canadien. Résultats : Bien que l’efficacité des IAP, comparativement aux placebos, soit bien établie, les données probantes des ERC sont équivoques quant à un avantage spécifique des APDG IAP, comparativement aux médicaments oraux, ce qui est probablement attribuable aux difficultés de mener de tels ERC. Les données probantes d’études moins rigoureuses sur le plan méthodologique et de la pratique clinique suggèrent certains avantages pour atteindre et maintenir la rémission, le risque de rechute, et l’hospitalisation. Le taux d’utilisation des IAP (AP de première génération et APDG), tiré des études publiées sur les patients externes, est faible à 6,3 % au Canada, comparativement à 15 % à 80 % dans le monde. Cependant, le taux d’utilisation est relativement élevé dans des programmes spécifiques de psychose précoce et conjointement avec les ordonnances de traitement en milieu communautaire au Canada. Conclusions : Les IAP sont au moins aussi efficaces que les AP par voie orale dans le traitement des troubles psychotiques. Les IAP peuvent présenter des avantages spécifiques pour les patients qui démontrent une non-observance secr

    Full Text Available Abstract Background Several clinical studies have established the efficacy, safety, and tolerability of long-acting risperidone administered once every 2 weeks in patients with schizophrenia or schizoaffective disorder. This report evaluates preliminary efficacy, safety, tolerability, and pharmacokinetic data for a novel (once-monthly administration of long-acting injectable risperidone 50 mg in patients with schizophrenia or schizoaffective disorder. Methods Clinically stable patients participated in a 1-year, open-label, single-arm, multicenter pilot study. During the 4-week lead-in phase, patients received long-acting risperidone 50 mg injections every 2 weeks, with 2 weeks of oral risperidone supplementation. Injections of long-acting risperidone 50 mg every 4 weeks followed for up to 48 weeks, without oral supplementation. The primary endpoint was relapse; other assessments included PANSS, CGI-S, adverse event reports, and determination of risperidone and 9-hydroxyrisperidone plasma concentrations. Results Twelve patients in the intent-to-treat population (n = 67 met relapse criteria (17.9%. Relapse risk at 1 year was estimated as 22.4%. Non-statistically significant improvements in symptoms (PANSS and clinical status (CGI-S at endpoint were observed. The most common adverse events included schizophrenia aggravated not otherwise specified (19.5%, anxiety (16.1%, insomnia (16.1%, and headache (11.5%. There were no unexpected safety and tolerability findings. Mean plasma concentrations for risperidone and 9-hydroxyrisperidone were generally stable during the study. Conclusion Once-monthly dosing of long-acting risperidone was well tolerated, associated with a relatively low relapse rate (similar to that reported with other antipsychotics, and maintained the clinically stable baseline status of most patients. Although the results suggest that some symptomatically stable patients with schizophrenia or schizoaffective disorder might be safely

    To examine characteristics of U.S. women that are associated with use of long-acting reversible contraception and changes in these characteristics between 2002 and 2006-2008. We analyzed data from two nationally representative samples of women aged 15-44 in the National Survey of Family Growth, including 7,643 women in 2002 and 7,356 women in 2006-2008. We conducted simple and multinomial logistic regression analyses to identify demographic and reproductive health characteristics associated with use of long-acting reversible contraception. Long-acting reversible contraception (intrauterine devices and subdermal implants) use among U.S. women using contraception increased from 2.4% in 2002 to 5.6% in 2006-2008. The largest increases in long-acting reversible contraception use during this time occurred among the youngest and oldest age groups, non-Hispanic white and non-Hispanic African American women, foreign-born women, and those in the highest income group. High prevalence of long-acting reversible contraception use in 2006-2008 was seen among women who had given birth once or twice (10%), foreign-born women (8.8%), and Hispanic women (8.4%). After adjusting for key demographic and reproductive health characteristics, in comparison with users of other contraceptive methods and with those not using contraception who were at risk for unintended pregnancy, foreign-born women and women who experienced coitarche before age 18 were approximately twice as likely to be using long-acting reversible contraception as women without those characteristics. A more diverse population of women used long-acting reversible contraception in 2006-2008 compared with 2002. However, there is likely more potential for increased uptake, especially among populations historically not considered to be candidates for these methods.

    To introduce and promote the use of long-acting reversible methods of contraception (LARC; intrauterine contraceptives and subdermal implant) by removing financial and knowledge barriers. The Contraceptive CHOICE Project is a prospective cohort study of 10,000 women 14-45 years who want to avoid pregnancy for at least 1 year and are initiating a new form of reversible contraception. Women screened for this study are read a script regarding long-acting reversible methods of contraception to increase awareness of these options. Participants choose their contraceptive method that is provided at no cost. We report the contraceptive choice and baseline characteristics of the first 2500 women enrolled August 2007 through December 2008. Sixty-seven percent of women enrolled (95% confidence interval, 65.3-69.0) chose long-acting methods. Fifty-six percent selected intrauterine contraception and 11% selected the subdermal implant. Once financial barriers were removed and long-acting reversible methods of contraception were introduced to all potential participants as a first-line contraceptive option, two-thirds chose long-acting reversible methods of contraception.

    Full Text Available Objective: to estimate the costs and effects of long-acting risperidone (LAR in the treatment of schizophrenic patients in Italy, as compared to conventional and oral atypical antipsychotics. Methods: a discrete event model was used. The model simulates patients. history for every single therapeutic alternative and selects incident events, on the basis of pre-defined probability distribution-powered, randomized repetitions. The model operates on two types of parameters: patient characteristics and time-dependent variables. Patient characteristics (age, sex, illness profile and severity, probability of incurring in an adverse event and potential dangerousness remain fixed during the 5 simulated years. Time-dependent variables are subject to changes and include outpatient visits, severity of psychotic episodes, symptom-scores, compliance, incidence of adverse effects, site of treatment and dangerousness. Three treatments have been selected: scenario 1 begins with LAR, switches to olanzapine and then to clozapine; scenario 2 starts with olanzapine, switches to oral risperidone and ends with clozapine. Direct medical costs have been computed on the basis of psychiatric visits, drug costs and costs of the institution in which the patient is treated (hospital, rehabilitation clinic, etc. Outcome measures were number of psychotic episodes in 5 years, total time spent during these episodes and cumulative score of positive and negative symptoms at 5 years. Information on alternatives, transition probabilities, model structure and health resources utilization were derived from the literature and from a panel of experts. Results: it has been estimated that LAR is economically dominant (more effective at lower cost respect to oral atypical antipsychotics, being able to prevent 0.87 psychotic episodes per patient, with a net cost saving of 4,773 euro per patient. Sub-group analysis indicate that LAR is always more effective than the considered alternatives

    The aim of this investigation was to determine the effect of sustained monophasic oral contraceptive pill (MOCP) use on the in vivo passive stiffness of the gastrocnemius medialis (GM) muscle-tendon unit. Twenty four females volunteered for this study (age range 20-25 yrs); twelve participants had been taking the combined MOCP for a minimum of 12 months, and twelve participants, who had never taken the MOCP, formed a control group. Distal displacement of the GM myotendinous junction (MTJ) was measured during passive dorsiflexion at 2 Nm increments to 20 Nm, and at end range of motion using ultrasonography. In addition, GM MTJ displacement was measured at passive torques equivalent to 5, 10 and 15% of plantarflexion maximal voluntary contraction (MVC) torque, and relative to GM length. MOCP users had significantly greater GM MTJ displacement at all passive torques (PMTJ displacement, passive muscle stiffness is less in MOCP using females, compared to non-pill users.

Both the twice-daily long-acting ß2-adrenoceptor agonists (LABAs salmeterol and formoterol and the once-daily LABA indacaterol are indicated for use in COPD. This review examines current evidence for the safety of LABAs in COPD, focusing on their effect on exacerbations and deaths.Methods: We searched PubMed for placebo-controlled studies evaluating long-term (≥24 weeks use of formoterol, salmeterol, or indacaterol in patients with stable COPD, published between January 1990 and September 2012. We summarized data relating to exacerbations and adverse events, particularly events related to COPD.Results: From 20 studies examined (8774 LABA-treated patients, there was no evidence of an association between LABA treatment and increased exacerbations, COPD-related adverse events, or deaths. Where analyzed as an efficacy outcome, LABA treatment was generally associated with significant or numerical reductions in COPD exacerbations compared with placebo. Incidences of COPD-related adverse events were similar for active and placebo treatments. The incidence of adverse events typically associated with the ß2-agonist drug class such as skeletal muscle tremors and palpitations was low (often <1% of patients, and there were no reports of increased incidence of cardiac arrhythmias. The systemic effects of ß2-adrenoceptor stimulation, such as high glucose and potassium levels, were considered minor.Conclusion: Current evidence from clinical studies of the

    Objective: The aim of this study was to evaluate the influence of oral contraceptive use on the silent period (SP) of anterior temporal and masseter muscles during the menstrual cycle. Materials and Methods: Totally, 28 women on reproductive age were selected including 15 nonusers of any hormone and 13 contraceptive users. All patients were dentate without muscular temporomandibular disorders. Electromyography (SP test) of the anterior temporal and masseter muscles was conducted every week during three consecutive menstrual cycles at 1st day of menstruation (P1), 7th day (P2), 14th day (P3) and 21st day (P4). Results: The SP values in the anterior temporal and masseter muscles were measured at both sides. The SP values of the right side (13.49 ms) at P2 were significantly different compared to the left side (12.28 ms). However, there was no significant difference on the interactions among the three factors. Conclusion: It can be concluded that the SP values in healthy women in reproductive age may not be influenced by the menstrual cycle with similar results for both muscles. PMID:26038645

    Full Text Available INTRODUCTION: GH induces acute insulin resistance in skeletal muscle in vivo, which in rodent models has been attributed to crosstalk between GH and insulin signaling pathways. Our objective was to characterize time course changes in signaling pathways for GH and insulin in human skeletal muscle in vivo following GH exposure in the presence and absence of an oral glucose load. METHODS: Eight young men were studied in a single-blinded randomized crossover design on 3 occasions: 1 after an intravenous GH bolus 2 after an intravenous GH bolus plus an oral glucose load (OGTT, and 3 after intravenous saline plus OGTT. Muscle biopsies were taken at t = 0, 30, 60, and 120. Blood was sampled at frequent intervals for assessment of GH, insulin, glucose, and free fatty acids (FFA. RESULTS: GH increased AUC(glucose after an OGTT (p<0.05 without significant changes in serum insulin levels. GH induced phosphorylation of STAT5 independently of the OGTT. Conversely, the OGTT induced acute phosphorylation of the insulin signaling proteins Akt (ser(473 and thr(308, and AS160.The combination of OGTT and GH suppressed Akt activation, whereas the downstream expression of AS160 was amplified by GH. WE CONCLUDED THE FOLLOWING: 1 A physiological GH bolus activates STAT5 signaling pathways in skeletal muscle irrespective of ambient glucose and insulin levels 2 Insulin resistance induced by GH occurs without a distinct suppression of insulin signaling proteins 3 The accentuation of the glucose-stimulated activation of AS 160 by GH does however indicate a potential crosstalk between insulin and GH.

    Large full-thickness oral defects involving the oral commissure continue to be a challenge for reconstructive surgeons. Although local flaps are the best option for full-thickness lip reconstruction, they are unavailable for large defects. In particular, recent advances in microsurgery have extended the available surgical options using free flaps, but for full-thickness large oral defects involving the oral commissure, it is still difficult to obtain good function and competence. The major disadvantages are the drooping and loosening of the reconstructed lip and the difficulty in restoring a natural oral commissure. We present two cases of lip reconstruction for full-thickness large defects involving the oral commissure in which free flaps with the muscle bow traction method were used to overcome these problems. In case 1, the lip was reconstructed with a free radial forearm-palmaris longus tendon composite flap. The tendon was sutured onto the orbicularis oris stumps. In case 2, the lip was reconstructed with a free anterolateral thigh flap including the fascia lata. A fascial strip in the flap was sutured to the residual orbicularis muscles. In each case, additional nonvascularised fascia lata was harvested and suspended the reconstructed lip in transverse direction as a muscle bow traction method. Both patients achieved good oral competence without medial deviation of the oral commissure and were able to resume a regular diet without drooping and loosening of the reconstructed lip. For large full-thickness oral defects involving the oral commissure, transverse fascial suspension with muscle bow traction is useful for functional and cosmetic reconstruction.

    A prospective, descriptive, analytic study was conducted at the Centre Hospitalier de Libreville in Gabon between February and September 2013 to evaluate acceptance of long-acting reversible contraceptives (LARC) and depot-medroxyprogesterone acetate (DMPA) following abortion. Women received counseling on the combined oral pill, DMPA, copper intrauterine devices (IUDs), and implants. The association between sociodemographic and clinical characteristics, knowledge of contraceptives, and acceptance was analyzed. Of the 383 women admitted with abortion complications, 206 (53.7%) knew of no systemic contraceptives. The best-known method was the oral pill (42.0%). Only 14 women (3.6%) knew of a LARC method (IUD or implants) and only 2 (0.5%) said the injectable was their best-known method. Over 90% accepted a modern contraceptive method after abortion. Two-thirds (66.8%) chose the pill, 14.6% DMPA, and 9.3% a LARC method. Only 9.1% of the women refused to initiate use of any method.

    Overactive bladder (OAB) and vaginal dryness are common problems after menopause. Oxybutynin (OXY) is an antimuscarinic agent that has been available for more than 30 years in the treatment of OAB patients. The aim of the work reported in this paper was to develop long acting mucoadhesive gel formulations of OXY and to investigate their effects on blood levels compared to those of oral OXY immediate release tablets, in rabbits. Mucoadhesive gels were prepared with chitosan, hydroxypropyl methylcellulose (HPMC K100M) and Poloxamer 407 (Pluronic F 127). The physicopharmaceutical properties of gels were evaluated. The gel formulation which was prepared with HPMC K100M, exhibited the highest viscosity, the greatest adhesiveness, cohesiveness and mucoadhesion values. The formulation which was prepared from HPMC K100M showed suitable permeation characteristics across the vaginal mucosa. Comparative bioavailability studies were carried out on rabbits with vaginal HPMC gel, vaginal chitosan gel, vaginal OXY solution and commercially available oral Üropan tablets. It was concluded that the highest AUC and relative bioavailability values were obtained for the bioadhesive vaginal gel formulation prepared with HPMC K100M. Therefore, the mucoadhesive vaginal gels of OXY can be a promising and innovative alternative therapeutic system for the treatment of OAB. It can be safely used in cases of overactive bladder and as well as vaginal dryness after menopause.

    2011-01-01

    Bronchodilators are the cornerstone of severe chronic obstructive pulmonary disease (COPD) treatment to improve airflow, symptoms, exercise tolerance, and exacerbations. There is convincing evidence that regular treatment with long-acting bronchodilators is more effective and convenient than treatment with short-acting bronchodilators. Long-acting β-2-agonists include the twice-daily drugs formoterol and salmeterol and, more recently, once-daily indacaterol. Studies with head-to-head comparisons of long-acting bronchodilators are scant, but novel data from controlled trials with the once-daily β(2)-agonist indacaterol indicate superior bronchodilation and clinical efficacy of indacaterol at recommended doses over twice-daily long-acting β(2)-agonists, and at least equipotent bronchodilation compared with once-daily tiotropium. The recent therapeutic developments in COPD underscore a shift from short-acting bronchodilators with multiple dosings per day to reduced dosing frequency and prolonged duration of action, including once-daily treatment, with more consistent effects on various clinical outcomes. This review summarizes relevant clinical data for twice-daily β-2-agonists in COPD, and further focuses on novel data for once-daily indacaterol, including head-to-head comparison trials.

    2007-05-01

    Surface electromyography (sEMG) was performed on randomly chosen adults with acute and recurrent tonsillitis to trace changes in muscle activity. Randomized prospective study. Activity of masseter (MS), submental (SUB), and infrahyoid muscles (INF) were examined and statistically analyzed during deglutition being compared to normative databases. For acute tonsillitis, the duration of muscle activity during deglutition was normal with normal amplitude, except for INF muscles. When the acute episode was over, no peculiarities remained. For recurrent tonsillitis, the duration of activity and SUB amplitude remains normal and activity of MS and INF became increased, and this abnormality remained during the remissions. Acute and recurrent tonsillitis affect muscle activity significantly by involving additional muscles (mainly infrahyoid) in swallowing. Acute tonsillitis triggers temporary electric hyperactivity of infrahyoid muscles. Recurrent tonsillitis affects MS and INF even during periods of remission (fixed pathological changes). This data might justify patients' complaints during the period of remission and can be used for comparison purposes to trace possible complications of tonsillitis.

    Surface electromyography (sEMG) studies were performed on 80 children with acute tonsillitis (AT) and 110 children with recurrent tonsillitis (RT), age 4-12 years, to trace sEMG changes of duration and amplitude of muscle activity during swallowing and continuous drinking. Prospective observational study of randomly chosen patients compared to normative database. Timing and amplitude (in muV) of activity of masseter, submental and infrahyoid muscles were evaluated during voluntary single swallows of saliva ("dry" swallow), water swallows, swallows of excessive amount of water (up to 15 ml), and continuous drinking of 50 ml of water. These parameters were measured for two age groups for both conditions: 4-8 and 9-12 years old. The previously established normative database was taken for control. AT presents prolonged duration of swallowing and electric hyperactivity of infrahyoid muscles but this activity returns to normal after recovery. RT affects masseter and infrahyoid muscles even during periods of remission but do not affect duration of swallowing activity. AT and RT in children age 4-12 years affects muscle activity during swallowing significantly by involving additional muscles (mainly infrahyoid) in this process. AT presents temporary electric hyperactivity of infrahyoid muscles. RT affects masseter and infrahyoid muscles even during periods of remission (pathologic changes are fixed). Abnormally high electric activity of masseter and infrahyoid muscles in patients with RT might serve as an additional indicator for tonsillectomy. Surface EMG of swallowing is a simple, non-invasive and reliable method for diagnostic and preoperative evaluation of dysphagia complaints associated with tonsillitis.

    This study was performed to determine the effects of expiratory muscle strength training (EMST) on the oral and respiratory functions of community-dwelling older people. Older people using a visiting-rehabilitation center were divided into an intervention group of 31 subjects and a control group of 15 subjects. Those in the intervention group were assigned home training for 8 weeks, which included 5 sets of 5 breaths per day with a 75% load of the maximum expiratory pressure using an EMST device. The outcome indices included (1) oral functions, evaluated by the cumulative time spent swallowing three times and the maximum phonation time (MPT) and (2) respiratory functions, evaluated by the maximum expiratory pressure and maximum inspiratory pressure (MEP/MIP). An independent t-test and paired t-test were used to analyze the data. The cumulative time spent swallowing three times was lower in the intervention group than in the control group. This difference remained significant even after adjusting for sex, age, and baseline values. The MPT was 2.1 seconds higher than baseline in the intervention group but 0.4 seconds lower than baseline in the control group. An average increase of 5.7 cmH2O in the PEmax was observed in the intervention group compared with an average decrease of 4.6 cmH2O in the control group, indicating a significant difference. These results suggest that EMST improves the oral and respiratory functions of community elderly subjects. This may be explained by the fact that the pathway for swallowing is partially shared with that for phonation, which contributes to a shortened swallowing time by repeated suprahyoid muscle contractions.

    Prior research has documented a modulating effect of taste on swallowing. We hypothesized that presentation of tastant stimuli would be a significant variable in swallowing-respiratory coordination, duration of oral bolus preparation, and submental muscle contraction. Twenty-three healthy females were presented with 1-cm(3) gelatin samples flavored with 4 tastants of increasing intensities. Visual analogue scale ratings of perceived intensity of each were used to identify relative equivalent concentrations across the 4 tastants. Data were then collected during ingestion of 5 trials of the 4 equivalent tastants using measurements of nasal airflow and submental surface electromyography (sEMG) to record biomechanical measures. Chi-square analysis failed to identify a statistically significant influence of taste on the phase location of swallowing apnea. Repeated measures analysis of variance demonstrated significant taste effects for oral preparation time, submental sEMG amplitude, and duration (P Swallow duration for sour, salty, and bitter tastants were longer than sweet and neutral tastants. Sour tastants resulted in the greatest amplitude of submental muscle contraction during swallowing. This study supports existing research that found that sour substances were swallowed with more effort when compared with other tastes.

    Full Text Available Abstract Background Previous studies reported divergent results on nutraceutical actions and free radical scavenging capability of ginseng extracts. Variations in ginsenoside profile of ginseng due to different soil and cultivating season may contribute to the inconsistency. To circumvent this drawback, we assessed the effect of major ginsenoside-Rg1 (Rg1 on skeletal muscle antioxidant defense system against exhaustive exercise-induced oxidative stress. Methods Forty weight-matched rats were evenly divided into control (N = 20 and Rg1 (N = 20 groups. Rg1 was orally administered at the dose of 0.1 mg/kg bodyweight per day for 10-week. After this long-term Rg1 administration, ten rats from each group performed an exhaustive swimming, and remaining rats considered as non-exercise control. Tibialis anterior (TA muscles were surgically collected immediately after exercise along with non-exercise rats. Results Exhaustive exercise significantly (p Conclusions This study provide compelling evidences that Rg1 supplementation can strengthen antioxidant defense system in skeletal muscle and completely attenuate the membrane lipid peroxidation induced by exhaustive exercise. Our findings suggest that Rg1 can use as a nutraceutical supplement to buffer the exhaustive exercise-induced oxidative stress.

    Women are at greater risk than men for certain kinds of diseases and injuries, which may at least partly be caused by sex hormonal differences. We aimed to test the influence of estradiol in vivo on collagen synthesis in tendon, bone, and muscle. Two groups of young, healthy women similar in age, body composition, and exercise-training status were included. The two groups were either habitual users of oral contraceptives exposed to a high concentration of synthetic estradiol and progestogens (OC, n = 11), or non-OC-users tested in the follicular phase of the menstrual cycle characterized by low concentrations of estradiol and progesterone (control, n = 12). Subjects performed 1 h of one-legged kicking exercise. The next day collagen fractional synthesis rates (FSR) in tendon and muscle connective tissue were measured after a flooding dose of [(13)C]proline followed by biopsies from the patellar tendon and vastus lateralis in both legs. Simultaneously, microdialysis catheters were inserted in vastus lateralis and in front of the patellar tendon for measurement of insulin-like growth factor I (IGF-I) and its binding proteins. Serum NH(2)-terminal propeptide of type I collagen (PINP) and urine COOH-terminal telopeptides of type-I collagen (CTX-I) were measured as markers for bone synthesis and breakdown, respectively. Tendon FSR and PINP were lower in OC compared with control. An increase in muscle collagen FSR postexercise was only observed in control (P collagen synthesis in tendon, bone, and muscle connective tissue, which may be related to a lower bioavailability of IGF-I.

    Phosphatidic acid (PA) is a diacyl-glycerophospholipid that acts as a signaling molecule in numerous cellular processes. Recently, PA has been proposed to stimulate skeletal muscle protein accretion, but mechanistic studies are lacking. Furthermore, it is unknown whether co-ingesting PA with other leucine-containing ingredients can enhance intramuscular anabolic signaling mechanisms. Thus, the purpose of this study was to examine if oral PA feeding acutely increases anabolic signaling markers and muscle protein synthesis (MPS) in gastrocnemius with and without whey protein concentrate (WPC). Overnight fasted male Wistar rats (~250 g) were randomly assigned to four groups: control (CON, n = 6-13), PA (29 mg; n = 8), WPC (197 mg; n = 8), or PA + WPC (n = 8). Three hours post-feeding, gastrocnemius muscle was removed for markers of Akt-mTOR signaling, gene expression patterns related to skeletal muscle mass regulation and metabolism, and MPS analysis via the SUnSET method. Compared to CON rats, PA, WPC and PA + WPC resulted in a significant elevation in the phosphorylation of mTOR (Ser2481) and rps6 (Ser235/236) (p < 0.05) in the gastrocnemius though there were no differences between the supplemented groups. MPS levels in the gastrocnemius were significantly (p < 0.05) elevated in WPC versus CON rats, and tended to be elevated in PA versus CON rats (p = 0.08), though MPS was less in PA + WPC versus WPC rats (p < 0.05) in spite of robust increases in mTOR pathway activity markers in the former group. C2C12 myoblast data agreed with the in vivo data herein showing that PA increased MPS levels 51% (p < 0.001) phosphorylated p70s6k (Thr389) levels 67% (p < 0.001). Our results are the first in vivo evidence to demonstrate that PA tends to increases MPS 3 h post-feeding, though PA may delay WPC-mediated MPS kinetics within a 3 h post-feeding window.

    Maintenance treatment with long-acting beta2-agonists and inhaled corticosteroids (LABA/ICS) can relieve asthma symptoms and reduce the frequency of exacerbations, but there are limited treatment options for people who do not gain control on combination LABA/ICS. Long-acting muscarinic antagonists (LAMA) are a class of inhaled drug which have been effective for people with chronic obstructive pulmonary disease and are now becoming available for people with asthma to take alongside their LABA/ICS inhaler. To assess the effects of adding a long-acting muscarinic antagonist (LAMA) to combination long-acting beta2-agonists (LABA) and inhaled corticosteroids (ICS) in adults whose asthma is not well controlled by LABA/ICS. We identified trials from the Cochrane Airways Review Group Specialised Register (CAGR) up to January 2016. We also searched ClinicalTrials.gov, the WHO trials portal, and reference lists of other reviews, and we contacted trial authors for additional information. We included parallel randomised controlled trials (RCTs) of at least 12 weeks' duration. Studies met the inclusion criteria if they compared LAMA as an add-on to LABA/ICS versus LABA/ICS alone for adults with asthma. We included studies reported as full text, those published as abstract only, and unpublished data. Primary outcomes were exacerbations requiring oral corticosteroids (OCS), validated measures of asthma control, and serious adverse events (including mortality). Two review authors screened searches and independently extracted details on risk of bias and numerical data. We analysed dichotomous data as odds ratios (ORs) and continuous data as mean differences (MD) using a random-effects model. We rated all outcomes using GRADE. We found four double-blind, double-dummy trials comparing LAMA to placebo, including 1197 people with asthma taking combination LABA/ICS. One of the trials was designed to study glycopyrronium bromide but was withdrawn prior to enrolment, and the other three

    Antibiotic usage is a vital component of veterinary medicine but the unique anatomy of some species can make administration difficult. The objective of this study was to determine the pharmacokinetic parameters of ceftiofur crystalline free acid (CCFA), a long-acting cephalosporin antibiotic, after parenteral administration in American flamingos ( Phoenicopterus ruber ). A dose of 10 mg/kg of CCFA was administered intramuscularly to 11 birds and blood was collected at various time points from 0 to 192 hr. Pharmacokinetic parameters for ceftiofur equivalents were determined and reached levels above minimum inhibitory concentrations of various bacterial organisms in other avian species through 96 hr in 9/11 birds. Based on these findings and comparison to other avian studies, ceftiofur crystalline free acid appears to be a long-acting antibiotic option for American flamingos. Administration of this antibiotic should be utilized in conjunction with culture and sensitivity of suspected pathogens.

    To determine whether long-acting muscarinic antagonists (LAMAs) provide superior therapeutic effects over long-acting β2 agonists (LABAs) for preventing COPD exacerbations. This was a systematic review and meta-analysis of randomized clinical trials involving patients with stable, moderate to severe COPD according to the Global Initiative for Chronic Obstructive Lung Disease criteria, treated with a LAMA (i.e., tiotropium bromide, aclidinium, or glycopyrronium), followed for at least 12 weeks and compared with controls using a LABA in isolation or in combination with a corticosteroid. A total of 2,622 studies were analyzed for possible inclusion on the basis of their title and abstract; 9 studies (17,120 participants) were included in the analysis. In comparison with LABAs, LAMAs led to a greater decrease in the exacerbation rate ratio (relative risk [RR] = 0.88; 95% CI: 0.84-0.93]; a lower proportion of patients who experienced at least one exacerbation (RR = 0.90; 95% CI: 0.87-0.94; p eventos adversos sérios (RR = 0,81; IC95%: 0,67-0,96; p = 0,0002). A qualidade geral das evidências foi moderada para todos os desfechos. O principal achado desta revisão sistemática e meta-análise foi que LAMAs reduziram significativamente a taxa de exacerbações (episódios de exacerbação/ano), os episódios de exacerbação, as hospitalizações e os eventos adversos sérios.

    Prevent hospitalizations in psychotic disorders is an important aim, so long-acting antipsychotic is a good option that can control better the correct adherence. Moreover, in the current economic context pharmacoeconomic studies are necessary. We estimate the effect in prevention of paliperidone palmitate long-acting injection (PP-LAI) and calculate the economic cost in the 12 months preceding the start of treatment with PP-LAI and 12 months later. Mirror image study of 71 outpatients diagnosed with psychotic disorders and treated with PP-LAI. In a first analysis, we measured along one year: number of hospitalizations/year, number of hospitalization in days, number of emergency assists/year and if there is antipsychotics associated to long-acting treatment. After this phase, we applied Fees Act of Valencia for economic analysis and estimate of the cost per hospitalization (€ 5,640.41) and hospital emergency (€ 187.61). After one year of treatment with PP-LAI (mean dose=130.65mg/month), we obtained greater numbers in assistance variables: total hospitalizations decrease, 78.8% (P=.009); shortening in hospitalization days, 89.4% (P=.009); abridgement of number of emergency assists, 79.1% (P=.002); decrease of rate of antipsychotics associated to long-acting treatment, 21% (P<.0001); increase in monotherapy, 53.8% (P<.0001). Therefore, after 12 months of treatment with PP-LAI we obtained a reduction in inpatient spending (savings of € 175,766.54) and increased spending on antipsychotics 32% (equivalent to € 151,126.92). PP-LAI can be an effective therapy for the treatment of patients with severe psychotic disorders: improves symptomatic stability and can prevent hospitalizations with cost-effective symptom control.

    The pharmacokinetics of oxytetracycline were studied in goats, after the intravenous and intramuscular injection of a conventional and long-acting formulation. The antibiotic was distributed according to an open two-compartment model. The apparent volume of distribution (Vz) and the central compartment volume (Vc) were 1.443 litres/kg and 0.453 litre/kg, respectively, and the total body clearance was 0.156 litre/kg/hour. The mean half-lives (T1/2 lambda z) of the conventional formulation after intravenous and intramuscular administration were six hours 28 minutes and 10 hours 38 minutes, respectively, whereas the long-acting formulation had half-lives of six hours 36 seconds and 29 hours, respectively, after intravenous and intramuscular injection. From the results of these single administrations two intramuscular dosage regimens can be proposed that achieve minimum concentrations of over 0.5 mg/litre (the minimum inhibitory concentration for most susceptible pathogens): with the conventional formulation by administering an initial dose of 10 mg/kg and a maintenance dose of 8.5 mg/kg every 24 hours, and with the long-acting formulation by administering an initial dose of 20 mg/kg and a maintenance dose of 14 mg/kg every 48 hours.

    The objective of this study was to determine the pharmacokinetics of a long-acting formulation of ceftiofur crystalline-free acid (CCFA) following intramuscular injection in ball pythons (Python regius). Six adult ball pythons received an injection of CCFA (15 mg/kg) in the epaxial muscles. Blood samples were collected by cardiocentesis immediately prior to and at 0.5, 1, 2, 4, 8, 12, 18, 24, 48, 72, 96, 144, 192, 240, 288, 384, 480, 576, 720, and 864 hr after CCFA administration. Plasma ceftiofur concentrations were determined by high-performance liquid chromatography. A noncompartmental pharmacokinetic analysis was applied to the data. Maximum plasma concentration (Cmax) was 7.096 +/- 1.95 microg/ml and occurred at (Tmax) 2.17 +/- 0.98 hr. The area under the curve (0 to infinity) for ceftiofur was 74.59 +/- 13.05 microg x h/ml and the elimination half-life associated with the terminal slope of the concentration-time curve was 64.31 +/- 14.2 hr. Mean residence time (0 to infinity) was 46.85 +/- 13.53 hr. CCFA at 15 mg/kg was well tolerated in all the pythons. Minimum inhibitory concentration (MIC) data for bacterial isolates from snakes are not well established. For MIC values of python. For MICs > or =0.5 microg/ml, more frequent dosing or a higher dosage may be required.

    The giant river shrimp (Macrobrachium rosenbergii), a native species of Thailand, is either exported for commercial purposes or supplied to meet the local requirements in Thailand. Limited pharmacokinetic information of the major antibiotic, oxytetracycline (OTC), is available for this freshwater shrimp. The purpose of the present study was to investigate the muscle tissue kinetics of OTC in M. rosenbergii following either intramuscular (i.m.) or oral (p.o.) administration at two dosages of 11 and 22 mg/kg body weight (b.w.). The concentration of OTC in shrimp tissues was measured using high-performance liquid chromatography (HPLC) equipped with a fluorescence detector. Muscle tissue concentrations were below the detection limit (LOD, 0.1 microg/g) after 96 and 120 h, following i.m. and p.o. administration, respectively. Peak muscle concentrations (C(max)) were 3.47 and 1.73 microg/g after i.m. and p.o. administration at a single dose of 11 mg/kg b.w. whereas they were 6.03 and 2.51 microg/g at a single dose of 22 mg/kg b.w., respectively. A noncompartment model was developed to describe the pharmacokinetics of OTC in the giant freshwater shrimp. The terminal half-lives of OTC were 28.68 and 28.09 h after i.m. and p.o. administration at a single dose of 11 mg/kg b.w., but 29.95 and 27.03 h at a single dose of 22 mg/kg b.w., respectively. The relative bioavailability was 82.32 and 64.67% following i.m. and p.o. administration, respectively. Based on the pharmacokinetic data, i.m. and p.o. administration with OTC at a dose of 11 mg/kg b.w. would be appropriate for use in giant freshwater shrimp farming. To avoid the OTC residue in shrimp muscle, it should take at least seven half-lives (8 days) to wash out the drug from the muscle of M. rosenbergii.

    Our objective was to investigate effects of acute and 2-week administration of oral salbutamol on repeated sprint ability, exercise performance, and muscle strength in elite endurance athletes. Twenty male elite athletes [VO2max: 69.4 ± 1.8 (Mean ± SE) mL/min/kg], aged 25.9 ± 1.4 years, were included in a randomized, double-blinded and placebo-controlled parallel study. At baseline, after acute administration, and again after 2-week administration of the study drugs (8 mg salbutamol or placebo), subjects' maximal voluntary contraction (MVC) of m. quadriceps and isometric endurance of m. deltoideus were measured, followed by three repeated Wingate tests. Exercise performance at 110% of VO2max was determined on a bike ergometer. Acute administration of salbutamol increased peak power during first Wingate test by 4.1 ± 1.7% (P salbutamol increased (P salbutamol had any effect on MVC, exercise performance at 110% of VO2max or on isometric endurance. No differences were observed in the placebo group. In conclusion, salbutamol benefits athletes' sprint ability. Thus, the present study supports the restriction of oral salbutamol in competitive sports.

    Full Text Available The aim of the present study was to evaluate the serial changes of GH and IGF-1 in seven patients with naïve, active acromegaly following presurgical treatment of the somatostatin analog pasireotide long-acting release (LAR and octreotide LAR. The patients were treated with pasireotide LAR with or without octreotide LAR for two years and underwent transsphenoidal adenomectomy. After treatment with the somatostatin analogs, the surgical cure rate was similar to that in patients who underwent transsphenoidal surgery alone. Diabetes insipidus was not identified in any patients after the operation. Pasireotide LAR was effective on GH as well as IGF-1 suppression and tumor size decreasing when used as the primary therapy. Future large-population studies to investigate the surgical curative rate after presurgical treatment with somatostatin analogs in patients with acromegaly and macroadenomas close to the cavernous sinus are warranted. However, that hyperglycemia developed following pre-surgical treatment with pasireotide should take into consideration.

    2015-12-01

    Unintended pregnancy remains high in the United States, accounting for one-half of pregnancies. Both contraceptive nonuse and imperfect use contribute to unplanned pregnancies. Long-acting reversible contraception (LARC) have greater efficacy than shorter acting methods. Data from large studies show that unplanned pregnancy rates are lower among women using LARC. However, overall use of LARC is low; of the reproductive age women using contraception, less than 10% are LARC users. Barriers include lack of knowledge and high up-front cost, and prevent more widespread use. Overcoming these barriers and increasing the number of women using LARC will decrease unplanned pregnancies and abortions.

    Maintaining antipsychotic therapy in psychosis is important in preventing relapse. Long-acting depot preparations can prevent covert non-adherence and thus potentially contribute to better patient outcomes. In this observational survey the main objective is to evaluate medication adherence and its determinants for oral treatment in a large sample of patients with psychosis. In this cross-sectional survey medication adherence for oral treatment was assessed by patients using the patient-rated Medication Adherence Questionnaire (MAQ). Data were collected by physicians on patients with a recent acute psychotic episode before switching to long-acting injectable risperidone. Other evaluations included disease severity (Clinical Global Impression - Severity), patients' insight (Positive and Negative Syndrome Scale item G12), treatment acceptance (clinician-rated Compliance Rating Scale), and therapeutic alliance (patient-rated 4-Point ordinal Alliance Scale). A total of 399 psychiatrists enrolled 1,887 patients (mean age 36.8±11.9 years; 61.6% had schizophrenia). Adherence to oral medication was "low" in 53.2% of patients, "medium" in 29.5%, and "high" in 17.3%. Of patients with psychiatrist-rated active acceptance of treatment, 70% had "medium" or "high" MAQ scores (Padherence was significantly associated with therapeutic alliance (4-Point ordinal Alliance Scale score; PPatient age was significantly associated with adherence: mean age increased with greater adherence (35.6, 36.7, and 38.6 years for patients with "low", "medium", and "high" levels of adherence, respectively; P=0.0007), while age adherence was also associated with a diagnosis of schizophrenia (P=0.0083), more severe disease (Clinical Global Impression - Severity ≥4; Padherence was low in most patients, with a strong positive association between self-reported adherence and psychiatrists' assessment of treatment acceptance. Understanding factors associated with poor medication adherence may help

LAI antipsychotics were most often used to facilitate regular treatment monitoring (49%, and 41% of psychiatrists thought that patients with low adherence who had failed oral therapy were well-suited for LAI antipsychotics. Only 4% of respondents saw LAI antipsychotics as appropriate for patients without other therapeutic options.Conclusion: Although efficacy and tolerability were the most common factors used to evaluate treatment success in schizophrenia, psychiatrists also consider QoL and global functioning to be important.

    Full Text Available The objective is to review β-adrenergic receptors and mechanisms in the immediate and late bronchial reaction in asthma and the new long-acting β-agonist. This will be discussed in light of the controversy of the potential adverse effect of regular use of long-acting β-agonists. We studied the effect of formoterol on the late asthmatic response (LAR and airway inflammation in guinea-pigs. Formoterol suppressed the LAR, antigen-induced airway inflammation and hyperresponsiveness, although isoproterenol failed to inhibit these parameters. β-Adrenergic hyporesponsiveness, and cholinergic and a- adrenergic hyperresponsiveness have been implicated in the pathogenesis of asthma. A decrease in β-adrenoreceptor function can result either from exogenously administered β-agonist or from exposure to allergens resulting in a late bronchial reaction. There is increasing evidence that eosinophils, macrophages, and lymphocytes which are of primary importance in the late bronchial reaction are also modulated by β2- adrenoreceptors. In functional studies of guinea-pig or human isolated trachea and lung parenchyma, PAF and certain cytokines significantly reduced the potency of isoproterenol to reverse methacholine- or histamine-induced contraction. The effect of glucocorticoids on pulmonary β-adrenergic receptors and responses suggests an important role for glucocorticoids to increase β-adrenergic receptors and responsiveness.

    Product monographs (also known by terms such as Summary of Product Characteristics and Highlights of Prescribing Information, depending on the jurisdiction) provide essential information to ensure the safe and effective use of a drug. Medical practitioners often rely on these monographs for guidance on matters related to pharmacokinetics as well as indications, contraindications, clinical pharmacology, and adverse reactions. The clinical and scientific information found within these documents, forming the basis for decision making, are presumed to be derived from well-designed studies. The objective of this review is to examine the source and validity of the pharmacokinetic data used in establishing the half-lives and times to steady-state reported in the product monographs of second-generation long-acting injectable antipsychotics. Thus, we have critically evaluated the clinical trials from which the pharmacokinetic parameters listed in the product monographs were determined. In many cases, the pharmacokinetic information presented in product monographs is of limited use to clinicians wishing to optimize the effectiveness and tolerability of second-generation long-acting injectable antipsychotics. Under such circumstances, off-label prescribing practices may actually produce better clinical outcomes than if decisions were made based on the product monographs alone.

    Full Text Available Achieving optimal glycemic control is an important aspect of preventing and slowing the progression of diabetes-associated complications, and reducing the cost of their treatment. Long-acting insulin analogues, glargine and detemir, provide better metabolic control with reduced risk of hypoglycaemia as compared to NPH insulin. However, fear of hypoglycaemia and weight gain, as well as the complexity of regimen, are still the most important barriers to well-timed initiation and intensification of insulin therapy. Insulin degludec (Tresiba® is a new ultra-long-acting insulin analogue. After subcutaneous injection degludec forms repository of soluble multi-hexamers, which are gradually absorbed to the bloodstream, providing a flat, stable antihyperglycemic effect lasting more than 42 h, and low intra-individual variability as opposed to currently used basal insulin analogues, insulin glargine and insulin detemir. In the seven randomized, open label, controlled phase 3 trials lasting 26 or 52 weeks, using treat-to-target (no more non-inferiority design, insulin degludec provided glycemic control similar to that of insulin glargine with lower risk of nocturnal hypoglycaemia and good safety profile in patients with type 1 or 2 diabetes. Furthermore, trials examining a flexible dosing regimen of insulin degludec in patients with type 1 or 2 diabetes have shown that it is possible to vary the injection time without compromising glycemic control or safety of the therapy.

    Evidence suggests a high unsatisfied demand for long acting and permanent contraceptive methods in sub-Saharan Africa. However, there is limited knowledge on demand for long acting and permanent contraceptive methods and associated factors in Ethiopia. The objective of this study was to assess demand for long acting and permanent contraceptive methods and associated factors among women of age group 18-49 years in Batu town, East Shoa Zone, Ethiopia. A facility based cross-sectional survey was conducted in six service delivery points from March to April 2009 on 398 women of age 18-49 years old. Thirteen (3%) were using long acting and permanent contraceptive methods and 89 (22.4%) wanted no more child in the future making the total demand of long acting and permanent contraceptive methods 24.4%. Older age group, multiparty, that the provider asked about reproductive intention, and the provider explained side effects of method selected were significantly associated with using LA and MPs (P contraceptive methods indicating that multi-dimensional measures are needed to improve the use of long acting and permanent contraceptive methods.

    AIM: To estimate if and to what extent long acting octreotide (LAR) improves survival and quality of life in patients with advanced hepatocellular carcinoma (HCC).METHODS: A total of 127 cirrhotics, stages A-B, due to chronic viral infections and with advanced HCC, were enrolled in the study. Scintigraphy with 111Indium labeled octreotide was performed in all cases. The patients with increased accumulation of radionuclear compound were randomized to receive either oral placebo only or octreotide/octreotide LAR only as follows: octreotide 0.5mg s.c. Every 8 h for 6 wk, at the end of wk 4-8 octreotide LAR 20 mg I.m. And at the end of wk 12 and every 4 wk octreotide LAR 30mg I.m.. Follow-up was worked out monthly as well as the estimation of quality of life (QLQ-C30 questionnaire). Patients with negative somatostatin receptors (SSTR) detection were followed up in the same manner.RESULTS: Scintigraphy demonstrated SSTR in 61 patients. Thirty were randomized to receive only placebo and 31 only octreotide. A significantly higher survival time was observed for the octreotide group (49±6 wk)as compared to the control group (28±1 wk) and to the SSTR negative group (28±2 wk), LR=20.39, df=2,P<0.01. The octreotide group presented 68.5% lower hazard ratio [95% CI (47.4%-81.2%)]. During the first year, a 22%, 39% and 43% decrease in the QLQ-C30 score was observed in each group respectively.CONCLUSION: The proposed therapeutic approach has shown to improve the survival and quality of life in SSTR positive patients with advanced HCC.

    Full Text Available Dustin J Costescu Department of Obstetrics and Gynaecology, McMaster University, Hamilton, ON, Canada Abstract: Unintended pregnancy is a significant global problem. In 2008, there were over 100 million unplanned pregnancies worldwide, representing approximately 41% of global conceptions. Family planning strategies in many countries are shifting from increasing the uptake of contraception among nonusers to increasing the uptake of the most effective methods among users of less effective methods. One of the most effective and acceptable methods of contraception is the levonorgestrel-releasing intrauterine system (LNG IUS; however, its uptake varies widely by country. This article reviews the currently available LNG IUSs, the rationale for increasing uptake of these methods, and evidence regarding safety, and discusses counseling strategies to best inform women about this option for contraception.

    Full Text Available Unintended pregnancies are an important public health issue. Long-acting reversible contraceptive methods (LARCs are reliable, safe, highly effective methods for most women; however they are underutilized in the United States. Shared decision aids were added to usual care in five public health family planning clinics in the Southeastern United States, staffed by advance practice nurses and registered nurses. All five sites showed an increase in the use of LARCs during the time period that shared decision aids were used (results statistically significant to p < 0.001. It is important for women to make informed choices about contraception, and shared decision aids can be utilized to support this decision making. This resource has been adopted for statewide use in all public health clinics, and implications for practice suggest that the use of shared decision aids is an effective method to support informed patient decision making and acceptance of LARC methods of contraception.

    Long-acting benzodiazepines (LABZs) are relatively contraindicated for elderly patients because they increase the risk of impaired cognitive function, falls, and hip fractures. The purpose of this study was to identify the characteristics of physicians who frequently prescribe LABZs for elderly patients. The authors examined the prescribing profile of 4,976 physicians who saw at least 20 elderly Quebec medicare registrants in 1990. Physicians who frequently prescribed LABZs for their elderly patients were more likely to have graduated before 1979, to be general practitioners as opposed to specialists, to practice in long-term care settings, and to have graduated from a medical school in Quebec as opposed to other schools in Quebec, in other provinces, or in other countries. The authors have identified several characteristics of physicians who frequently prescribed LABZs for the elderly. Strategies to improve prescribing in this field should target this group of physicians.

    Asthma is a complex disease where many patients remain symptomatic despite guideline-directed therapy. This suggests an unmet need for alternative treatment approaches. Understanding the physiological role of muscarinic receptors and the parasympathetic nervous system in the respiratory tract will provide a foundation of alternative therapeutics in asthma. Currently, several long-acting muscarinic antagonists (LAMAs) are on the market for the treatment of respiratory diseases. Many studies have shown the effectiveness of tiotropium, a LAMA, as add-on therapy in uncontrolled asthma. These studies led to FDA approval for tiotropium use in asthma. In this review, we discuss how the neurotransmitter acetylcholine itself contributes to inflammation, bronchoconstriction, and remodeling in asthma. We further describe the current clinical studies evaluating LAMAs in adult and adolescent patients with asthma, providing a comprehensive review of the current known physiological benefits of LAMAs in respiratory disease.

    There have been limited research studies concerning the use of libido inhibitors for the treatment of patients with a paraphilia. Observational studies suggest that agents that lower testosterone are an effective treatment for paraphilia. We report a case of hormonal treatment of paraphilia that was associated with side effects. A 35-year-old man with a paraphilia was treated with long-acting gonadorelin. The desired result was reduced preoccupation with sexuality, but there were various side effects including a serious amount of bone loss. We believe that more attention should be given to the adverse effects of long-term treatment with triptorelin. In our view the drug regime needs to be revised.

    Most pregnancies among teenagers are unintended and many can be attributed to contraception misuse or nonuse. The etonogestrel implant and intrauterine devices, referred to as long-acting reversible contraceptives, or LARCs, are the most effective reversible contraceptive methods. These methods are safe for use by adolescents, yet the number of LARC users remains low among adolescents in the United States. In this review we examine recent literature about barriers and facilitators to LARC use among adolescent women. Factors that influence decision-making and provision are organized into 4 categories: (1) cost and clinical operations; (2) adolescent awareness and attitudes; (3) confidentiality, consent, and parental attitudes; and (4) health care provider knowledge, attitudes, and counseling. Knowledge deficits and misconceptions among adolescents and their health care providers are key barriers to adolescent LARC use.

    Full Text Available Abstract Background Staphylococcus aureus releases virulence factors (VF that may impair the innate protective functions of airway cells. The aim of this study was to determine whether a long-acting β2 adrenergic receptor agonist (salmeterol hydroxynaphthoate, Sal combined with a corticosteroid (fluticasone propionate, FP was able to regulate ion content and cytokine expression by airway glandular cells after exposure to S. aureus supernatant. Methods A human airway glandular cell line was incubated with S. aureus supernatant for 1 h and then treated with the combination Sal/FP for 4 h. The expression of actin and CFTR proteins was analyzed by immunofluorescence. Videomicroscopy was used to evaluate chloride secretion and X-ray microanalysis to measure the intracellular ion and water content. The pro-inflammatory cytokine expression was assessed by RT-PCR and ELISA. Results When the cells were incubated with S. aureus supernatant and then with Sal/FP, the cellular localisation of CFTR was apical compared to the cytoplasmic localisation in cells incubated with S. aureus supernatant alone. The incubation of airway epithelial cells with S. aureus supernatant reduced by 66% the chloride efflux that was fully restored by Sal/FP treatment. We also observed that Sal/FP treatment induced the restoration of ion (Cl and S and water content within the intracellular secretory granules of airway glandular cells and reduced the bacterial supernatant-dependent increase of pro-inflammatory cytokines IL8 and TNFα. Conclusions Our results demonstrate that treatment with the combination of a corticosteroid and a long-acting β2 adrenergic receptor agonist after bacterial infection restores the airway glandular cell function. Abnormal mucus induced by defective ion transport during pulmonary infection could benefit from treatment with a combination of β2 adrenergic receptor agonist and glucocorticoid.

Indacaterol was the first agent of the novel family of very long-acting β2-agonists to be used as an inhaled bronchodilator for COPD and provides 24-hour therapeutic action, thus allowing once-daily administration. Data from clinical trials show that indacaterol has a bronchodilator effect similar to that of the anticholinergic tiotropium bromide and slightly higher efficacy compared with the long-acting β2-agonists, salmeterol and formoterol. Moreover, the safety profile is excellent and comparable with that of placebo. Concerning adherence with drug treatment and real-life management in respect to long-acting β2-agonists, once-daily dosing makes indacaterol more convenient for COPD patients and is likely to enhance patient adherence. Other very long-acting β2-agonists currently in development include vilanterol, olodaterol, and carmoterol, and these have shown good characteristics for clinical use in the studies reported thus far.

    To compare, from the perspective of third-party payers in the United States health care system, the cost-effectiveness of olanzapine long-acting injection (LAI, depot) with alternative antipsychotic agents including risperidone-LAI, paliperidone-LAI, haloperidol-LAI, and oral olanzapine, in the treatment of patients with schizophrenia who have been non-adherent or partially adherent with oral antipsychotics. A 1-year micro-simulation economic decision model was developed to simulate the dynamics of usual care of patients with schizophrenia who continue, discontinue, switch, or restart their medication. The model uses a range of clinical and cost parameters including adherence levels, relapse with and without hospitalization, quality-adjusted life years (QALYs), treatment discontinuation rates by reason, treatment-emergent adverse events, suicide, health care resource utilization, and direct health care costs. Published medical literature and a clinical expert panel were used to develop baseline model assumptions. Key model outputs include annual total direct cost (US$) per treatment and incremental cost-effectiveness values per additional QALY gained. Model results found that the olanzapine-LAI treatment strategy was more effective (greater QALYs) and less costly than risperidone-LAI, paliperidone-LAI, and haloperidol-LAI. In addition, olanzapine-LAI was both more effective and more costly, with an estimated incremental cost/QALY of $26,824 compared to oral olanzapine. The base-case and multiple sensitivity analyses found olanzapine-LAI to remain within acceptable cost-effective ranges (micro-simulation model finds the olanzapine-LAI treatment strategy to result in better effectiveness and to be a cost-effective alternative compared to oral olanzapine and the LAI formulations of risperidone, paliperidone, and haloperidol in the treatment of non-adherent and partially adherent patients with schizophrenia in the United States.

    Women’s initial understandings and anticipated acceptability of long-acting vaginal gels as potential anti-HIV microbicides was investigated by exploring the perceptibility variables associated with prototype formulations. Four focus groups with 29 women, aged 18–45, were conducted to consider gel prototypes with varied physicochemical and rheological properties. Participants responded favorably to the concept of long-acting vaginal gels as microbicides. Distinctions in understandings and stated needs regarding product dosing, characteristics, and effectiveness offer valuable insights into product design. Long-acting vaginal gels capable of protecting against HIV/STIs will be a viable option among potential users, with dosing frequency being an important factor in willingness to use. PMID:24248674

These have focused in part on improving access to contraception through national campaigns. This study assessed teenage pregnancy and abortion rate trends since 1998 and possible associations with usage of long-acting reversible contraceptives (LARCs. Methods: Teenage conception rates and age-specific abortion rates were obtained from the Office for National Statistics and the Department of Health. LARC usage data was obtained for Depo-Provera, Implanon/Nexplanon, intrauterine devices, Mirena, and Noristerat from the IMS British Pharmaceutical Index, IMS Hospital Pharmacy Audit, IMS Disease Analyzer, and KT-31 reports. Through linear regression methods, changes in conception and abortion-related outcomes during 1998–2011 and the associations with LARC usage were assessed. Results: Conception rates for girls younger than 18 years of age decreased significantly between 1998–2011, from 46.6 to 30.7 per 1,000 girls. A statistically significant association was observed between this decrease and increased LARC usage (P=0.0024 in this population. Abortion rates among females aged <18 years or aged 18–19 years decreased between 1998–2011, and their associations with increased LARC usage were statistically significant (P=0.0029 and P=0.0479, respectively. The pattern in older women was complex; abortion rates in women aged 20–24 years or 25–34 years increased slightly from 1998 to 2011, with stabilization during 2007–2011. Conclusion: Increased LARC usage in England was significantly associated with decreased teenage pregnancy rates

Phase III pivotal trials have documented that olodaterol Respimat Soft Mist inhaler 5 µg induces fast onset of bronchodilation, comparable with formoterol at day 1. Moreover, significant lung function improvements have been documented up to 48 weeks in patients with moderate to very severe chronic obstructive pulmonary disease (COPD. Olodaterol was generally well tolerated and had an acceptable cardiovascular and respiratory adverse event profile. Regrettably, the clinical development of olodaterol is however still too partial to draw any firm conclusions on the positioning of this ultra-LABA as monotherapy in the management of COPD. Waiting for further data on the impact of olodaterol on different patient-reported outcomes, which however are widely available for indacaterol, and mainly for a head-to-head comparison between these two ultra-LABAs and between olodaterol long-acting antimuscarinic antagonists other than tiotropium, we believe it is correct to follow the clinical indications of indacaterol also for olodaterol. In any case, the parallel bronchodilating modes of action of olodaterol and tiotropium make them an attractive combination in COPD. The results from the ongoing large TOviTO Phase III trial program have documented the efficacy and safety of olodaterol/tiotropium fixed-dose combination as maintenance therapy in patients with moderate to very severe COPD. In particular, olodaterol/tiotropium fixed-dose combination provides

    From a historical perspective, this article describes the use of antipsychotic long-acting injections (LAI) in the treatment of schizophrenia, a disorder that was defined in the final years of the 19th century. An efficient treatment for schizophrenia was discovered only in 1952 with the introduction of chlorpromazine, a phenothiazine derivative. Fairly soon, antipsychotics became available as LAI. The first compounds were fluphenazine enanthate (1966) and decanoate (1968) whose development is attributed to G.R. Daniel, a medical director at Squibb & Sons. Other first-generation antipsychotics long-acting injections (FGA-LAIs) were introduced in a rapid succession in the 1960s and 1970s. FGA-LAIs made a key contribution to the development of community psychiatry. As neuroleptics emptied psychiatric hospitals, it was important to ensure that patients could be taken care of in outpatient facilities. FGA-LAIs prevented covert non-compliance. Compliance was further reinforced by the social and psychological support of patients. The introduction of second-generation antipsychotics (SGA) led to a loss of interest in FGA-LAIs. This is evidenced by a drop in the number of papers published on this topic. The interest in LAI was revived with the introduction of the first SGA-LAI in 2003. Four different preparations have been approved in the decade between 2003 and 2013. SGA-LAIs differ from FGA-LAIs in the technology that is used to produce the depot effect, and also in the treatment objectives. The rationale for using SGA-LAIs is not only to prevent relapses due to treatment interruption, but also to achieve more constant plasma levels in order to reduce side effects due to excessive plasma levels and loss of efficacy due to insufficient plasma levels. Also, treatment objectives are no longer limited to controlling acute symptoms. Treatment objectives now include the alleviation of negative symptoms and cognitive deficits that are key prognostic factors. Copyright © 2014

    The pharmacokinetic properties of a long-acting formulation of chloramphenicol were determined in six yearling cattle after a single intravenous (i.v.) administration (40 mg/kg body weight) and after two sequential subcutaneous (s.c.) or intramuscular (i.m.) administrations (90 mg/kg/48 h). The two extravascular routes were studied during a crossover trial for a bioequivalence test. After i.v. administration, the plasma concentration-time graph was characteristic of a two-compartment open model. Mean values were a half-life of 4.1 h, a volume of distribution of 0.86 l/kg and a body clearance of 0.128 l/kg/h. Plasma concentrations of chloramphenicol following i.m. and s.c. administrations increased slowly to a broad peak at 10-15 micrograms/ml between 9 and 12 h. Bioavailability was 19.1% after i.m. injection and 12.4% after s.c. administration. The extent of absorption from the two routes did not differ significantly. The rate of absorption was significantly lower after s.c. application than it was after i.m. injection. The time necessary for the plasma concentration to exceed 5 micrograms/ml was the same for the two routes. Thus, i.m. and s.c. routes are bioequivalent.

    Full Text Available Background: Long-acting therapy in laboratory animals offers advantages over the current practice of 2-3 daily drug injections. Yet little is known about the disintegration of biodegradable drug implants in rodents. Objective: Compare bioavailability of buprenorphine with the biodegradation of lipid-encapsulated subcutaneous drug pellets. Methods: Pharmacokinetic and histopathology studies were conducted in BALB/c female mice implanted with cholesterol-buprenorphine drug pellets. Results: Drug levels are below the level of detection (0.5 ng/mL plasma within 4-5 days of implant. However, necroscopy revealed that interstitial tissues begin to seal implants within a week. Visual inspection of the implant site revealed no evidence of inflammation or edema associated with the cholesterol-drug residue. Chemical analyses demonstrated that the residues contained 10-13% of the initial opiate dose for at least two weeks post implant. Discussion: The results demonstrate that biodegradable scaffolds can become sequestered in the subcutaneous space. Conclusion: Drug implants can retain significant and unintended reservoirs of drugs.

    To identify factors involved in women's decisions to choose particular contraceptive methods and more specifically, incentives and disincentives to use three long-acting reversible contraceptive (LARC) methods: injectables, implants, and intrauterine devices/systems (IUDs/IUSs). A total of 502 women aged 18 to 30 completed a cross-sectional online questionnaire. The three most important factors in choosing a contraceptive method were: high efficacy at preventing pregnancy, protection against sexually transmitted infections, and non-interference with sexual intercourse. The most common incentives for LARC use were the high efficacy and long duration of action. Disincentives included the possibility of irregular bleeding and concerns about effects on fertility; fear of needles and pain was a particular disincentive for IUD/IUS use. Only 93 (18%) of the participants reported ever having used a LARC. Reported disincentives to LARC use (e.g., concern about effects on future fertility) indicated that many young women hold inaccurate beliefs about these methods. The relatively high proportions of women who held neutral attitudes about LARCs (21-40%, depending on the method) highlight the importance of education and contraceptive counselling to improve knowledge about the advantages of these methods.

    Acromegaly is a human disease of growth hormone (GH) excess with considerable morbidity and increased mortality. Somatostatin analogues are first line medical treatment but the disease remains uncontrolled in up to 40% of patients. GH receptor (GHR) antagonist therapy is more effective but requires frequent high-dose injections. We have developed an alternative technology for generating a long acting potent GHR antagonist through translational fusion of a mutated GH linked to GH binding protein and tested three candidate molecules. All molecules had the amino acid change (G120R), creating a competitive GHR antagonist and we tested the hypothesis that an amino acid change in the GH binding domain (W104A) would increase biological activity. All were antagonists in bioassays. In rats all antagonists had terminal half-lives >20 hours. After subcutaneous administration in rabbits one variant displayed a terminal half-life of 40.5 hours. A single subcutaneous injection of the same variant in rabbits resulted in a 14% fall in IGF-I over 7 days.

    Long acting, single injection caudal anesthesia with mepivacaine was studied in 1,208 obstetrical cases. A 1 per cent solution was used in 671 patients and compared with a 1.5 per cent concentration in 537. No remarkable differences were found between the two groups. The 1 per cent solution provided relief of labor discomfort for from 60 to 180 minutes with an average of 110 minutes. In contrast, the 1.5 per cent solution provided an average of 115 minutes with a range of 80 to 210 minutes. A total volume of 30 ml of anesthetic agent yielded anesthesia to a level of the tenth thoracic vertebra or higher in 91 per cent of patients. Significant alterations in blood pressure were uncommon. About 1 per cent of patients required a vasopressor because of a drop in systolic blood pressure below 80 mm of mercury. Another 8 per cent had a drop of over 20 points in systolic pressure but from high enough levels that they did not require a vasopressor. Toxic effects similar to those of lidocaine were found in slightly more than 1 per cent of cases. This anesthesia requires a higher incidence of operative intervention for delivery. PMID:5980717

    Probiotics, i.e., bacteria expressing therapeutic peptides (protein), are used as a new type of orally administrated biologic drugs to treat diseases. To develop yeast strains which could effectively prevent and treat type 2 diabetes mellitus, we firstly constructed the yeast integrating plasmid pNK1-PGK which could successfully express green fluorescent protein (GFP) in Saccharomyces cerevisiae. The gene encoding ten tandem repeats of glucagon-like peptide-1(10 × GLP-1) was cloned into the vector pNK1-PGK and the resulting plasmids were then transformed into the S. cerevisiae INVSc1. The long-acting GLP-1 hypoglycemic yeast (LHY) which grows rapidly and expresses 10 × GLP-1 stably was selected by nutrition screening and Western blotting. The amount of 10 × GLP-1 produced by LHY reached 1.56 mg per gram of wet cells. Moreover, the oral administration of LHY significantly reduced blood glucose level in type 2 diabetic mice induced by streptozotocin plus high fat and high sugar diet.

    Bronchodilators are central drugs in the management of patients with chronic obstructive pulmonary disease (COPD). Indacaterol was the first agent of the novel family of very long-acting β2-agonists to be used as an inhaled bronchodilator for COPD and provides 24-hour therapeutic action, thus allowing once-daily administration. Data from clinical trials show that indacaterol has a bronchodilator effect similar to that of the anticholinergic tiotropium bromide and slightly higher efficacy compared with the long-acting β2-agonists, salmeterol and formoterol. Moreover, the safety profile is excellent and comparable with that of placebo. Concerning adherence with drug treatment and real-life management in respect to long-acting β2-agonists, once-daily dosing makes indacaterol more convenient for COPD patients and is likely to enhance patient adherence. Other very long-acting β2-agonists currently in development include vilanterol, olodaterol, and carmoterol, and these have shown good characteristics for clinical use in the studies reported thus far.

    Sepsis is a leading cause of death in intensive care units worldwide. Low availability of glutamine contributes to the catabolic state of sepsis. L-Glutamine supplementation has antioxidant properties and modulates the expression of heat shock proteins (HSPs). This study investigated the effects of oral supplementation with L-glutamine plus L-alanine (GLN+ALA), both in the free form and L-alanyl-L-glutamine dipeptide (DIP), on glutamine-glutathione (GSH) axis and HSPs expression in endotoxemic mice. B6.129F2/J mice were subjected to endotoxemia (lipopolysaccharides from Escherichia coli, 5 mg.kg(-1), LPS group) and orally supplemented for 48 h with either L-glutamine (1 g.kg(-1)) plus L-alanine (0.61 g.kg(-1)) (GLN+ALA-LPS group) or 1.49 g.kg(-1) of DIP (DIP-LPS group). Endotoxemia reduced plasma and muscle glutamine concentrations [relative to CTRL group] which were restored in both GLN+ALA-LPS and DIP-LPS groups (P<.05). In supplemented groups were re-established GSH content and intracellular redox status (GSSG/GSH ratio) in circulating erythrocytes and muscle. Thiobarbituric acid reactive substance was 4-fold in LPS treated mice relative to the untreated CTRL group, and plasma TNF-α and IL-1β levels were attenuated by the supplements. Heat shock proteins 27, 70 and 90 (protein and mRNA) were elevated in the LPS group and were returned to basal levels (relative to CTRL group) in both GLN+ALA-LPS and DIP-LPS groups. Supplementations to endotoxemic mice resulted in up-regulation of GSH reductase, GSH peroxidase and glutamate cysteine ligase mRNA expression in muscle. In conclusion, oral supplementations with GLN+ALA or DIP are effective in reversing the conditions of LPS-induced deleterious impact on glutamine-GSH axis in mice under endotoxemia.

    The effect of the dietary supplementation to lambs of essential oils (EOs) from rosemary (Rosmarinus officinalis) and artemisia (Artemisia herba alba) on the antioxidant status of muscle and on meat oxidative stability was studied. Eighteen Barbarine lambs were divided into 3 groups and for 95days received oat hay and concentrates. One group (C) was not supplemented, while the other two groups received 400mg/kg of EOs from rosemary (R400) or artemisia (A400). Both EOs possessed antioxidant properties and their oral administration improved the reducing and radical scavenging capacity of the muscle compared to the C treatment (P<0.01). Nevertheless, supplementing EOs did not exert protection against lipid oxidation and did not affect the colour stability in meat over 7days of aerobic storage.

    Short-acting calcium antagonists have a deleterious effect on the prognosis for patients with myocardial ischemia, possibly caused by overactivation of sympathetic nerves due to vasodilatation, negative inotropism, or coronary steal. However, there is considerable debate about whether long-acting calcium antagonists as well as the short-acting calcium antagonists have the same effect. Barnidipine-HCl is a newly-developed calcium antagonist with 1:2 short- and long-acting particles. This study evaluated the changes of autonomic tone due to barnidipine. Both the short- and long-acting effect of the calcium antagonist was evaluated. Eleven patients with primary hypertension underwent 24-hour ambulatory electrocardiogram and blood pressure monitoring before and after the treatment with barnidipine. Heart rate and blood pressure were compared before and after the medication. Heart rate variability was analyzed with a Marquette 8000/T. High frequency power (HF), as a parameter of vagal tone, and the ratio to low frequency power (LF), as a parameter of sympathetic tone, were obtained. Twenty-four-hour average blood pressure decreased significantly during the day, but nocturnal hypotension was not observed. Heart rate did not increase. HF decreased at the peak of the short- and long-acting components. LF/HF increased at the peak of the short-acting component. Short-acting particles of barnidipine had a deleterious effect on the autonomic tone, that is overactivation of sympathetic tone and suppression of vagal tone. Long-acting particles of barnidipine suppressed the vagal tone. These findings suggest that short-acting calcium antagonists may cause arrhythmia or deterioration of coronary ischemia.

    Obesity induces low-grade chronic inflammation, manifested by proinflammatory polarization of adipose tissue innate and adaptive resident and recruited immune cells that contribute to insulin resistance (IR). The glucose-dependent insulinotropic polypeptide (GIP) is an incretin hormone that mediates postprandial insulin secretion and has anabolic effects on the adipose tissue. Importantly, recent evidence suggested that GIP is a potential suppressor of inflammation in several metabolic models. In this study, we aimed to investigate the immunoregulatory role of GIP in a murine model of diet-induced obesity (DIO) using the long-acting GIP analog [d-Ala(2)]GIP. Administration of [d-Ala(2)]GIP resulted in adipocytes of increased size, increased levels of adipose tissue lipid droplet proteins, indicating better lipid storage capacity, and reduced adipose tissue inflammation. Flow cytometry analysis revealed reduced numbers of inflammatory Ly6C(hi) monocytes and F4/80(hi)CD11c(+) macrophages, associated with IR. In addition, [d-Ala(2)]GIP reduced adipose tissue infiltration of IFN-γ-producing CD8(+) and CD4(+) T cells. Furthermore, [d-Ala(2)]GIP treatment induced a favorable adipose tissue adipokine profile, manifested by a prominent reduction in key inflammatory cytokines (TNF-α, IL-1β, IFN-γ) and chemokines (CCL2, CCL8, and CCL5) and an increase in adiponectin. Notably, [d-Ala(2)]GIP also reduced the numbers of circulating neutrophils and proinflammatory Ly6C(hi) monocytes in mice fed regular chow or a high-fat diet. Finally, the beneficial immune-associated effects were accompanied by amelioration of IR and improved insulin signaling in liver and adipose tissue. Collectively, our results describe key beneficial immunoregulatory properties for GIP in DIO and reveal that its augmentation ameliorates adipose tissue inflammation and improves IR.

    Although goat milk production represents today a very small percentage of the world milk market, this percentage has been growing continuously during the past 20 years. Goat milk is the basic milk supply in many developing countries and provides tasteful derivative products in developed countries. Goats, as well as all milk-producing animals, can be affected by mastitis, but goats being considered a minor species, few drugs are specifically registered for these animals; most, at least for mastitis treatment, are usually tested and registered for use in cows. This situation leads often to the adoption for goat milk of withdrawal periods defined for cows even if these extrapolations prove almost never valid for goats. In the present study, the elimination of the β-lactam antibacterial agent ampicillin in goat milk was investigated. Ampicillin was chosen because it is one of the most common antibiotics used by goat farmers against mastitis due to the fact that it is well tolerated and has short elimination times in cows. Goats were treated with long-acting ampicillin at 15 mg (kg of body weight)(-1) by double intramuscular injection at 72 h interval. Milk was collected in a 12 h milking scheme. The method used to determine the levels of ampicillin in goat milk was based on a liquid-liquid extraction of this drug from the matrix, successive derivatization with formaldehyde, and final separation by HPLC with fluorescence detection. The results point out a slow depletion of ampicillin and, consequently, a withdrawal period (13 milkings) longer than that extrapolated and authorized for cows and sheep.

    The rate of teenage pregnancy in the United States is higher than in other developed nations. Teenage births result in substantial costs, including public assistance, health care costs, and income losses due to lower educational attainment and reduced earning potential. The Contraceptive CHOICE Project was a large prospective cohort study designed to promote the use of long-acting, reversible contraceptive (LARC) methods to reduce unintended pregnancy in the St. Louis region. Participants were educated about reversible contraception, with an emphasis on the benefits of LARC methods, were provided with their choice of reversible contraception at no cost, and were followed for 2 to 3 years. We analyzed pregnancy, birth, and induced-abortion rates among teenage girls and women 15 to 19 years of age in this cohort and compared them with those observed nationally among U.S. teens in the same age group. Of the 1404 teenage girls and women enrolled in CHOICE, 72% chose an intrauterine device or implant (LARC methods); the remaining 28% chose another method. During the 2008-2013 period, the mean annual rates of pregnancy, birth, and abortion among CHOICE participants were 34.0, 19.4, and 9.7 per 1000 teens, respectively. In comparison, rates of pregnancy, birth, and abortion among sexually experienced U.S. teens in 2008 were 158.5, 94.0, and 41.5 per 1000, respectively. Teenage girls and women who were provided contraception at no cost and educated about reversible contraception and the benefits of LARC methods had rates of pregnancy, birth, and abortion that were much lower than the national rates for sexually experienced teens.

    Full Text Available Recent asthma recommendations advocate the use of long-acting beta-agonists (LABAs in uncontrolled asthma, but also stress the importance of stepping down this therapy once asthma control has been achieved. The objective of this study was to evaluate downtitration of LABA therapy in pediatric patients who are well-controlled on combination-inhaled corticosteroid (ICS/LABA therapy. Clinical and physiologic outcomes were studied in children with moderate-to-severe persistent asthma after switching from combination (ICS/LABA to monotherapy with ICS. Of the 54 patients, 34 (63% were determined to have stable asthma after the switch, with a mean followup of 10.7 weeks. Twenty (37% had loss of asthma control leading to addition of leukotriene receptor antagonists, increased ICS, or restarting LABA. There were 2 exacerbations requiring treatment with systemic steroids. In patients with loss of control, there was a statistically significant decline in FEV1 (−8% versus −1.9%, =0.03 and asthma control test (−3.2 versus −0.5, =0.03. This did not approach significance for FEF25-75%, exhaled nitric oxide, lung volumes or airway reactivity. No demographic, asthma control measures, or lung function variables predicted loss of control. Pediatric patients with moderate-to-severe persistent asthma who discontinue LABA therapy have a 37% chance of losing asthma control resulting in augmented maintenance therapies. Recent recommendations of discontinuing LABA therapy as soon as control is achieved should be evaluated in a prospective long-term study.

We analyzed a total of 16,446 patients who had been prescribed a LAMA between January 1, 2013 and December 31, 2013. The follow-up period, based on a centralized system of electronic prescription management, was extended until December 2014.Results: During 2013, the medication collected was 7.4%–10.7% higher than indicated by labeling. This was very similar for all LAMAs, irrespective of the patient’s sex, the molecule, the device, and the drug dosage. We did not observe seasonal variations in the consumption of LAMAs, nor did we detect differences between prescription drugs for once-daily (every 24 hours versus twice-daily (every 12 hours administration, between the different molecules, or between different types of inhalers for the same molecule. The results were similar in 2014.Conclusion: The principal conclusion of this study is that, in an area with a centralized management system of pharmacological prescriptions, adherence to treatment with LAMAs is very high, irrespective of the molecules or inhalation device. We did not find that patients who used twice-daily medication had a lower adherence. Keywords: COPD, treatment, adherence, LABAs, LAMAs, PDC, asthma

    Full Text Available The aim of this study was to evaluate the response of prepubertal ewe lambs to exogenous administration of either medroxyprogesterone acetate (MAP or long-acting progesterone (LAP together with biostimulation. Two Pool Dorset adult males and 75 mixed-breed prepubertal ewe lambs (average of 179 days-old and 30.0kg were used. The females were randomly assigned to three different groups. In the first group the females were submitted to the insertion of intravaginal sponges containing MAP (60 mg for 12 days and were then biostimulated for eight weeks. In the second group the females were submitted to a single injection of LAP (225 mg and then to biostimulation for eight weeks. In the last group, the females were only submitted to biostimulation for eight weeks. Animals were considered cyclic when plasma progesterone (P4 concentration exceeded 1.0 ng/mL in at least one of two consecutive blood samples taken within a 7-day interval in three distinct experimental moments. After treatments 93.3% of the females disregarding their group started their cyclicity and most of them (92.0%, continued to be cyclic after 63 days of either MAP or LAP together with biostimulation under both male and female effect. We conclude that prepubertal ewe lambs when submitted to protocols of either MAP or LAP followed by biostimulation result in puberty at the 7 month of age. It can be deducted that some ewe lambs submitted to the administration of either MAP or LAP together with biostimulation promoted a multiplier effect upon the other young females that were then stimulated to start cyclicity.

    Study objective To describe and explore provider- and patient-level perspectives regarding long-acting reversible contraception (LARC) for teens and young adults (ages 16-24). Methods Data collection occurred between June – December 2011. We first conducted telephone interviews with administrative directors at 20 publicly funded facilities that provide family planning services. At six of these sites, we conducted a total of six focus group discussions (FGDs) with facility staff and forty-eight in-depth interviews (IDIs) with facility clients ages 16-24. Results Staff in the FGDs did not generally equate being a teen with ineligibility for IUDs. In contrast to staff, one quarter of the young women did perceive young age as rendering them ineligible. Clients and staff agreed that the “forgettable” nature of the methods and their duration were some of LARC’s most significant advantages. They also agreed that fear of pain associated with both insertion and removal and negative side effects were disadvantages. Some aspects of IUDs and implants were perceived as advantages by some clients but disadvantages by others. Common challenges to providing LARC-specific services to younger patients included extra time required to counsel young patients about LARC methods, outdated clinic policies requiring multiple visits to obtain IUDs, and a perceived higher removal rate among young women. The most commonly cited strategy for addressing many of these challenges was securing supplementary funding to support the provision of these services to young patients. Conclusion Incorporating young women’s perspectives on LARC methods into publicly funded family planning facilities’ efforts to provide these methods to a younger population may increase their use among young women.

    Post-abortion initiation of long-acting reversible contraception (LARC) reduces subsequent abortion rates within 24 months, but the prevalence of post-abortion LARC use in New Zealand is unknown. To describe post-abortion initiation of intrauterine and implantable LARC methods in New Zealand between 2007 and 2012, and to determine what impact the introduction of government-funded (free) levonorgestrel (LNG) implants in August 2010 had on overall LARC use. Retrospective observational study involving New Zealand abortion clinic data. Nationally collated data on post-abortion LARC insertions were obtained for the period 2007-2012, and individual-level discharge data for patients attending a large urban hospital abortion clinic were analysed using descriptive statistics to describe annual uptake rates, and the demographic profile of LARC users during this period. Logistic regression analyses examined whether LARC use differed by parity and/or age over time. Post-abortion LARC use increased from 20.2% in 2007 to 45.6% in 2012. Intrauterine device use increased from 20.2% to 31.8% during this period, with implants contributing a further 14% to the overall use of LARC methods by 2012. Clinic data showed that LARC use increased among most demographic subgroups between 2009 and 2012, with the greatest increase among nulliparous under-20-year-olds (from 17.2% to 42.0%). Post-abortion LARC use has been steadily increasing in New Zealand since 2007. Overall LARC use significantly increased following the introduction of government-funded implants, particularly among young and nulliparous women. Improving access to alternative methods of LARC may further increase uptake and reduce unwanted pregnancy rates. Published by the BMJ Publishing Group Limited.

    The current recombinant human growth hormone (rhGH) therapy requires daily subcutaneous (sc) injections, which results in poor patient compliance, especially in young children. To reduce the dosing frequency, we generated a chimeric protein of rhGH and the Fc-domain of immunoglobulin G (IgG) (rhGH-Fc). The pharmacokinetics and pharmacodynamics of sc-injected rhGH-Fc were assessed in male Sprague-Dawley rats and hypophysectomized rats, respectively. A single sc injection of rhGH-Fc at a dose of 0.2 mg/kg slowly reached a Cmax of 16.80 ng/mL and remained for 7 days with a half-life of 51.1 h. Conversely, a single sc injection of rhGH 0.2 mg/kg rapidly reached a Cmax of 46.88 ng/mL and declined with a half-life of 0.55 h to baseline values in 4 h. In the efficacy study, the sc-injected rhGH-Fc induced rapid weight gain and tibial width growth at a dose of 240 μg/animal. The effect of two injections of rhGH-Fc separated by 1 week was comparable to that of the same dose of 14 daily injections of rhGH. The rhGH-Fc is a novel candidate for long-acting rhGH therapy with more convenient weekly administration, as it reduces glomerular filtration and receptor-mediated clearance while allowing for the rapid reversal of potential adverse events.

    Long-acting reversible contraceptive (LARC) methods-IUDs and implants-are more effective than other reversible methods, yet are little used in the United States. Examining which U.S. women use LARC methods and how they differ from users in other low-fertility countries may help point the way toward increasing use. Data from married or cohabiting women participating in the National Survey of Family Growth (2008-2010) and in eight countries' Generations and Gender Programme surveys (2004-2010) were used in bivariate and multinomial logistic regression analyses examining LARC use within each setting. The proportion of contraceptive use accounted for by LARC methods was generally greater in Europe (10-32%) than in the United States (10%) and Australia (7%). Compared with LARC use among comparable groups in other countries, use was particularly low among U.S. women who were married, were aged 40-44 or had had three or more children, yet was comparatively high among 18-24-year-olds. Among U.S. women, those aged 35-39 or 40-44 were more likely than 18-29-year-olds to rely on sterilization rather than on LARC methods (odds ratios, 3.0 and 10.7, respectively), those who had had three or more children were more likely to do so than were those who had had none or one (4.9), and women who had completed college were less likely than those who had not finished high school to do so (0.4). Certain subgroups of U.S. women may benefit from the reversibility and effectiveness of LARC methods. Copyright © 2014 by the Guttmacher Institute.

    Long-acting reversible contraceptive (LARC) methods (IUDs and implants) are the most effective and cost-effective methods for women. Although they are safe to place immediately following an abortion, most clinics do not offer this service, in part because of the increased cost. In 2009, telephone interviews were conducted with 20 clinicians and 24 health educators at 25 abortion care practices across the country. A structured topic guide was used to explore general practice characteristics; training, knowledge and attitudes about LARC; and postabortion LARC counseling and provision. Transcripts of the digitally recorded interviews were coded and analyzed using inductive and deductive processes. Respondents were generally positive about the safety and effectiveness of LARC methods; those working in clinics that offered LARC methods immediately postabortion tended to have greater knowledge about LARC than others, and to perceive fewer risks and employ more evidence-based practices. LARC methods often were not included in contraceptive counseling for women at high risk of repeat unintended pregnancy, including young and nulliparous women. Barriers to provision were usually expressed in terms of financial cost--to patients and clinics--and concerns about impact on the smooth flow of clinic procedures. Education and encouragement from professional colleagues regarding LARC, as well as training and adequate reimbursement for devices, were considered critical to changing clinical practice to include immediate postabortion LARC provision. Despite evidence about the safety and cost-effectiveness of postabortion LARC provision, many clinics are not offering it because of financial and logistical concerns, resulting in missed opportunities for preventing repeat unintended pregnancies.

    To quantify uptake of long-acting reversible contraceptives (LARC)-intrauterine devices (IUDs) and hormonal implants-among U.S. Army active-duty female soldiers and identify characteristics associated with uptake. This retrospective cohort study used the Stanford Military Data Repository, which includes all digitally recorded health encounters for active-duty U.S. Army soldiers from 2011 to 2014. We analyzed data from women aged 18-44 years to assess rates of LARC initiation using medical billing codes. We then evaluated predictors of LARC initiation using multivariable regression. Among 114,661 servicewomen, 14.5% received a LARC method; among those, 60% received an IUD. Intrauterine device insertions decreased over the study period (38.7-35.9 insertions per 1,000 women per year, β=0.14, 95% confidence interval [CI] -0.23 to -0.05, Pimplant insertions (20.3-35.4/1,000 women per year, β=0.41, CI 0.33-0.48, Pimplant users were in the youngest age category (18-22 years) compared with 9.6% and 2.0% in the oldest (36-44 years). The likelihood of uptake among the youngest women (compared with oldest) was most marked for implants (adjusted relative risk 7.12, CI 5.92-8.55; Pimplant use. Unmarried and childless soldiers were less likely to initiate LARC. These findings are consistent with potential underutilization and a need for education about LARC safety and reversibility in a population facing unique consequences for unintended pregnancies.

Long-acting depot preparations can prevent covert non-adherence and thus potentially contribute to better patient outcomes. In this observational survey the main objective is to evaluate medication adherence and its determinants for oral treatment in a large sample of patients with psychosis.Methods: In this cross-sectional survey medication adherence for oral treatment was assessed by patients using the patient-rated Medication Adherence Questionnaire (MAQ. Data were collected by physicians on patients with a recent acute psychotic episode before switching to long-acting injectable risperidone. Other evaluations included disease severity (Clinical Global Impression – Severity, patients’ insight (Positive and Negative Syndrome Scale item G12, treatment acceptance (clinician-rated Compliance Rating Scale, and therapeutic alliance (patient-rated 4-Point ordinal Alliance Scale.Results: A total of 399 psychiatrists enrolled 1,887 patients (mean age 36.8±11.9 years; 61.6% had schizophrenia. Adherence to oral medication was “low” in 53.2% of patients, “medium” in 29.5%, and “high” in 17.3%. Of patients with psychiatrist-rated active acceptance of treatment, 70% had “medium” or “high” MAQ scores (P<0.0001. Medication adherence was significantly associated with therapeutic alliance (4-Point ordinal Alliance Scale score; P<0.0001. Patient age was significantly associated with adherence: mean age increased with greater adherence (35.6, 36.7, and 38.6 years for patients with “low”, “medium”, and “high” levels of adherence

    The aim of this study was to evaluate the bioequivalence of two commercial long-acting formulations based on oxytetracycline (OTC) hydrochloride between the reference formulation (Terramycin LA, Pfizer) and a test formulation (Cyamicin LA, Fort Dodge Saude Animal). Both formulations were administered in a single intramuscular route at a dose of 20 mg OTC/kg of body weight in clinically healthy bovines. The study was carried out according to a one-period parallel design. Plasma samples were analyzed by high-pressure liquid chromatography. The limit of quantitation was 0.050 μg/mL with an accuracy of 101.67% with a coefficient of variation of 13.15%. Analysis of variance and 90% confidence interval tests were used to compare the bioavailability parameters (maximum plasma concentration, Cmax, and the area under the concentration-versus-time curve extrapolated to infinity, AUC0–∞) of both products. In the case of the time to maximum concentration (Tmax), non-parametric tests based on Wilcoxon’s signed rank test were preferred. The comparison of the mean AUC0–∞ values did not reveal any significant differences (311.40 ± 93.05 μg h/mL and 287.71 ± 45.31 μg h/mL, respectively). The results were similar for the Tmax (3.58 ± 0.90 h versus 3.42 ± 0.51 h). However, when comparing the mean Cmax some significant differences were found (8.73 ± 3.66 μg/mL and 10.43 ± 3.84 μg/mL, respectively). The 90% confidence intervals for the ratio of AUC0–∞ and Tmax values for the reference and test product are within the interval 80–125%, but the 90% confidence intervals for the ratio of Cmax falls outside the proposed interval. It was concluded that Cmax of test product are not within the 20% of those of the reference, thus suggesting that test OTC is not bioequivalent to the reference formulation. PMID:27446938

    In conflict-affected states, vouchers have reduced barriers to reproductive health services and have enabled health programs to use targeted subsidies to increase uptake of specific health services. Vouchers can also be used to channel funds to public- and private-service providers and improve service quality. The Yamaan Foundation for Health and Social Development in Yemen and the Marie Stopes Society (MSS) in Pakistan-both working with Options Consultancy Services-have developed voucher programs that subsidize voluntary access to long-acting reversible contraceptives (LARCs) and permanent methods (PMs) of family planning in their respective fragile countries. The programs focus on LARCs and PMs because these methods are particularly difficult for poor women to access due to their cost and to provider biases against offering them. Using estimates of expected voluntary uptake of LARCs and PMs for 2014 based on contraceptive prevalence rates, and comparing these with uptake of LARCs and PMs through the voucher programs, we show the substantial increase in service utilization that vouchers can enable by contributing to an expanded method choice. In the governorate of Lahj, Yemen, vouchers for family planning led to an estimated 38% increase in 2014 over the expected use of LARCs and PMs (720 vs. 521 expected). We applied the same approach in 13 districts of Punjab, Khyber Pakhtunkhwa (KPK), and Sindh provinces in Pakistan. Our calculations suggest that vouchers enabled 10 times more women than expected to choose LARCs and PMs in 2014 in those areas of Pakistan (73,639 vs. 6,455 expected). Voucher programs can promote and maintain access to family planning services where existing health systems are hampered. Vouchers are a flexible financing approach that enable expansion of contraceptive choice and the inclusion of the private sector in service delivery to the poor. They can keep financial resources flowing where the public sector is prevented from offering services

    Skeletal muscle is mainly composed of myofibers and intramuscular connective tissue. Bundles composed of many myofibers, with each myofiber sheathed in connective tissue called the endomysium, are packed in the perimysium, which occupies the vast bulk of the intramuscular connective tissue. The perimysium is a major determination factor for muscle texture. Some studies have reported that collagen peptide (Col-Pep) ingestion improves the connective tissue architecture, such as the tendon and dermis. The present study evaluated the effects of Col-Pep ingestion on the chicken iliotibialis lateralis (ITL) muscle. Chicks were allocated to three groups: the 0.15% or 0.3% Col-Pep groups and a control group. Col-Pep was administered by mixing in with commercial food. On day 49, the ITL muscles were analyzed by morphological observation and the textural property test. The width of the perimysium in the 0.3% Col-Pep group was significantly larger than other two groups. Although scanning electron microscopic observations did not reveal any differences in the architecture of the endomysium, elastic improvement of the ITL muscle was observed as suggested by an increase of the width of perimysium and improved rheological properties. Our results indicate that ingestion of Col-Pep improves the textural property of ITL muscle of chickens by changing structure of the perimysium.

    2013-01-01

    Background Currently, there is a lack of studies examining the effects of adenosine-5′-triphosphate (ATP) supplementation utilizing a long-term, periodized resistance-training program (RT) in resistance-trained populations. Therefore, we investigated the effects of 12 weeks of 400 mg per day of oral ATP on muscular adaptations in trained individuals. We also sought to determine the effects of ATP on muscle protein breakdown, cortisol, and performance during an overreaching cycle. Methods The study was a 3-phase randomized, double-blind, and placebo- and diet-controlled intervention. Phase 1 was a periodized resistance-training program. Phase 2 consisted of a two week overreaching cycle in which volume and frequency were increased followed by a 2-week taper (Phase 3). Muscle mass, strength, and power were examined at weeks 0, 4, 8, and 12 to assess the chronic effects of ATP; assessment performance variables also occurred at the end of weeks 9 and 10, corresponding to the mid and endpoints of the overreaching cycle. Results There were time (p jump power (+ 796 ± 75 ATP vs. 614 ± 52 watts placebo, p < 0.001); and greater ultrasound determined muscle thickness (+4.9 ± 1.0 ATP vs. (2.5 ± 0.6 mm placebo, p < 0.02) with ATP supplementation. During the overreaching cycle, there were group x time effects for strength and power, which decreased to a greater extent in the placebo group. Protein breakdown was also lower in the ATP group. Conclusions Our results suggest oral ATP supplementation may enhance muscular adaptations following 12-weeks of resistance training, and prevent decrements in performance following overreaching. No statistically or clinically significant changes in blood chemistry or hematology were observed. Trial registration ClinicalTrials.gov NCT01508338 PMID:24330670

    Somatostatin analogs control GH/IGF-1 excess in acromegaly. Somatostatin receptors also mediate the complex effects of somatostatin on the gastrointestinal tract and may be defensive in inflammatory bowel diseases, such as ulcerative colitis. We present a patient who showed good response to long-acting octreotide (OCT-LAR) treatment in terms of both acromegaly and ulcerative colitis (UC). A 58-year-old female patient with diagnosis of acromegaly and ulcerative colitis was started on long-acting somatostatin treatment as a first-line treatment for acromegaly as she refused to undergo transsphenoidal surgery. During the follow-up period, a significant amelioration was also observed in the course of ulcerative colitis, and clinical remission of both diseases was achieved uneventfully. Somatostatin appears to be a promising candidate in the treatment of inflammatory bowel diseases. © 2016 John Wiley & Sons Ltd.

    The use of long-acting avermectins (AVMs) in cattle to treat infections with gastrointestinal nematodes was common in Brazil until its prohibition by state authorities. The prohibition; however, was rescinded in 2015, but a scientific discussion of the pros and cons of the use of these formulations is necessary. We evaluated the levels of resistance to 1.0 and 3.5% doramectin and to 3.15% ivermectin in cattle. The worms in animals treated with 3.5% doramectin were characterized by the suppression of oviposition and by a higher proportion of adult females carrying no eggs. Haemonchus placei, Cooperia punctata, C. pectinata, C. spatulata, and Oesophagostomum radiatum were resistant to the above compositions. The administration of long-acting AVM formulations did not result in a higher efficacy against these helminth populations.

    A 35-year-old man with a paraphilia was treated with long-acting gonadorelin. The desired result was reduced preoccupation with sexuality, but there were various side effects including a serious amount of bone loss. We believe that more attention should be given to the adverse effects of long-term treatment with triptorelin. In our view the drug regimen needs to be revised.

    These experiments tested the hypothesis that long-acting oxytetracycline (oxytetracycline-LA) was more effective than regular oxytetracycline in preventing porcine pleuropneumonia when administered either 24 or 48 h prior to experimental challenge with virulent strains of Actinobacillus pleuropneumoniae. Two experiments (1 and 2) were conducted using growing pigs (average weight 12-15 kg). Antibiotic treatments were administered once intramuscularly at 20 mg/kg body weight; controls received ...

    Full Text Available Background. Long acting and permanent contraceptive methods have the potential to reduce unintended pregnancies but the contraceptive choice and utilization in Ethiopia are highly dominated by short term contraceptives. Objective. To assess the knowledge and perception on long acting and permanent contraceptives of married women and men in Northern Ethiopia. Method. A qualitative method was conducted in Adigrat on January, 2012. Four focus group discussions with married women and men and six in-depth interviews with family planning providers were conducted. Content analysis was used to synthesize the data. Result. Participants’ knowledge on long acting and permanent contraceptives is limited to recognizing the name of the methods. Most of the participants are not able to identify permanent methods as a method of contraception. They lack basic information on how these methods work and how they can use it. Women had fears and rumors about each of these methods. They prefer methods which do not require any procedure. Family planning providers stated as they have weakness on counseling of all contraceptive choices. Conclusion. There are personal barriers and knowledge gaps on these contraceptive methods. Improving the counseling service program can help women to increase knowledge and avoid misconceptions of each contraceptive choice.

    Full Text Available Abstract Background Chronic obstructive pulmonary disease (COPD is the 4th leading cause of mortality worldwide. Long-acting bronchodilators are considered first line therapies for patients with COPD but their effects on mortality are not well known. We performed a comprehensive systematic review and meta-analysis to evaluate the effects of long-acting bronchodilators on total mortality in stable COPD. Methods Using MEDLINE, EMBASE and Cochrane Systematic Review databases, we identified high quality randomized controlled trials of tiotropium, formoterol, salmeterol, formoterol/budesonide or salmeterol/fluticasone in COPD that had a follow-up of 6 months or longer and reported on total mortality. Two reviewers independently abstracted data from the original trials and disagreements were resolved by iteration and consensus. Results Twenty-seven trials that included 30,495 patients were included in the review. Relative risk (RR for total mortality was calculated for each of the study and pooled together using a random-effects model. The combination of inhaled corticosteroid (ICS and long-acting beta-2 agonist (LABA therapy was associated with reduced total mortality compared with placebo (RR, 0.80; p = 0.005. Neither tiotropium (RR, 1.08; p = 0.61 nor LABA by itself (RR, 0.90; p = 0.21 was associated with mortality. Conclusions A combination of ICS and LABA reduced mortality by approximately 20%. Neither tiotropium nor LABA by itself modifies all-cause mortality in COPD.

    Full Text Available Glucagon-like peptide-1 (GLP-1 is glucose-dependent insulinotropic hormone secreted from enteroendocrine L cells. Its long-acting analogue, exendin-4, is equipotent to GLP-1 and is used to treat type 2 diabetes mellitus. In addition, exendin-4 has effects on the central and peripheral nervous system. In this study, we administered repeated intraperitoneal (i.p. injections of exendin-4 to examine whether exendin-4 is able to facilitate the recovery after the crush nerve injury. Exendin-4 injection was started immediately after crush injury and was repeated every day for subsequent 14 days. Rats subjected to sciatic nerve crush exhibited marked functional loss, electrophysiological dysfunction, and atrophy of the tibialis anterior muscle (TA. All these changes, except for the atrophy of TA, were improved significantly by the administration of exendin-4. Functional, electrophysiological, and morphological parameters indicated significant enhancement of nerve regeneration 4 weeks after nerve crush. These results suggest that exendin-4 is feasible for clinical application to treat peripheral nerve injury.

    We compared the effectiveness of topical ketoprofen in Transfersome(®) gel (IDEA-033) with oral ketoprofen and drug-free Sequessome™ vesicles (FLEXISEQ(®) Sport; TDT 064) in reducing calf muscle soreness. One hundred and sixty eight healthy individuals with a pain score ≥ 3 (10-point scale) 12-16 h post-exercise (walking down stairs with an altitude of 300-400 m) were randomised to receive IDEA-033 plus oral placebo (two dose groups), oral ketoprofen plus TDT 064, or TDT 064 plus oral placebo. The primary endpoint was muscle soreness reduction from pre-dosing to Day 7. Higher pain scores were recorded with oral ketoprofen plus TDT 064 (mean ± s 462.4 ± 160.4) versus IDEA-033 plus oral placebo (434.7 ± 190.8; P = 0.2931) or TDT 064 plus oral placebo (376.2 ± 159.1; P = 0.0240) in the 7 days post-exercise. Recovery from muscle soreness was longer with oral ketoprofen plus TDT 064 (mean 91.0 ± 19.5 h) versus IDEA-033 plus placebo (mean 81.4 ± 22.9 h; P = 0.5964) or TDT 064 plus placebo (mean 78.9 ± 22.8 h; P = 0.0262). In conclusion, ultradeformable phospholipid vesicles ± ketoprofen did not retard recovery from muscle soreness. TDT 064 improves osteoarthritis-related pain and could be of interest as a treatment for joint pain during and post-exercise.

    Inhaled corticosteroids (ICS) used in COPD (chronic obstructive pulmonary disease) are recommended only in combination with a long-acting beta2-agonist (LABA) in stage 3 and higher in COPD treatment guidelines. In comparison to placebo and the single components, a superior control by means of the ICS/LABA fixed combination therapy has been demonstrated for clinical improvement in the following parameters: reduction of exacerbation rate and hospitalisations, reduction of dyspnoea and improvement of forced expiratory volume in one second (FEV1). In contrast to data from database studies, the large prospective TORCH (Towards a Revolution in COPD Health) trial found in the ICS/LABA group a beneficial effect on the reduction of mortality only as a trend in the ICS/LABA group, which did not reach statistical significance. In long-term trials, ICS treated patients experienced up to 10% oral and/or pharyngeal candidiasis. ICS was associated with an excess risk of pneumonia, which doubles the pneumonia incidence in patients not receiving ICS. The probability of having pneumonia reported as an adverse event was 18-19 % in the ICS groups and resulted in a 1.7-2.2 elevated pneumonia risk. Because ICS therapy is recommended only in conjunction with a bronchodilator, fixed ICS/LABA combinations are a logical consequence for COPD long-term therapy.

    Congenital hyperinsulinism (CHI) is a common cause of hypoglycaemia due to unregulated insulin secretion from pancreatic β cells. Medical management includes use of oral diazoxide (a KATP channel agonist) and daily injectable octreotide (somatostatin analogue) therapy. However, diazoxide is associated with severe sideeffects such as coarse facies, hypertrichosis and psychosocial/compliance issues in adolescents. Lanreotide (a long-acting somatostatin analogue) is used in adults with neuroendocrine tumours; however, its role in patients with CHI has not been well described. A 15-year-old girl with diazoxide-responsive CHI had severe hypertrichosis secondary to diazoxide and subsequent compliance/psychosocial issues. She was commenced on 30 mg of lanreotide every 4 weeks as a deep subcutaneous injection, in an attempt to address these issues. She was able to come off diazoxide treatment 2 months after starting lanreotide. Presently, after 2.5 years of lanreotide treatment, her blood glucose control is stable with complete resolution of hypertrichosis. Clinically significant improvements in the self-reported Paediatric Quality of Life (PedsQL) questionnaire and Strengths and Difficulties Questionnaire (SDQ) were reported after 1 year on lanreotide. No side effects were found, and her liver/thyroid function and abdominal ultrasound have been normal. We report the first case on the use of lanreotide in an adolescent girl with diazoxide-responsive CHI with significant improvement of quality of life. © 2015 S. Karger AG, Basel.

    Full Text Available Abstract Chronic obstructive pulmonary disease (COPD is characterized by progressive airflow limitation and debilitating symptoms. For patients with moderate-to-severe COPD, long-acting bronchodilators are the mainstay of therapy; as symptoms progress, guidelines recommend combining bronchodilators from different classes to improve efficacy. Inhaled long-acting β2-agonists (LABAs have been licensed for the treatment of COPD since the late 1990s and include formoterol and salmeterol. They improve lung function, symptoms of breathlessness and exercise limitation, health-related quality of life, and may reduce the rate of exacerbations, although not all patients achieve clinically meaningful improvements in symptoms or health related quality of life. In addition, LABAs have an acceptable safety profile, and are not associated with an increased risk of respiratory mortality, although adverse effects such as palpitations and tremor may limit the dose that can be tolerated. Formoterol and salmeterol have 12-hour durations of action; however, sustained bronchodilation is desirable in COPD. A LABA with a 24-hour duration of action could provide improvements in efficacy, compared with twice-daily LABAs, and the once-daily dosing regimen could help improve compliance. It is also desirable that a new LABA should demonstrate fast onset of action, and a safety profile at least comparable to existing LABAs. A number of novel LABAs with once-daily profiles are in development which may be judged against these criteria. Indacaterol, a LABA with a 24-hour duration of bronchodilation and fast onset of action, is the most advanced of these. Preliminary results from large clinical trials suggest indacaterol improves lung function compared with placebo and other long-acting bronchodilators. Other LABAs with a 24-hour duration of bronchodilation include carmoterol, vilanterol trifenatate and oldaterol, with early results indicating potential for once-daily dosing in

    Late complications of head and neck cancer survivors include neck muscle atrophy and soft-tissue fibrosis. We present an autopsy case of neck muscle atrophy and soft-tissue fibrosis (sternocleidomastoid, omohyoid, digastric, sternohyoid, sternothyroid, and platysma muscles) within the radiation field after modified radical neck dissection type I and postoperative radiotherapy for floor of mouth cancer. A 70-year-old man underwent primary tumor resection of the left floor of mouth, left marginal mandibulectomy, left modified radical neck dissection type I, and reconstruction with a radial forearm free flap. The patient received adjuvant radiotherapy. The dose to the primary tumor bed and involved neck nodes was 63 Gy in 35 fractions over 7 weeks. Areas of subclinical disease (left lower neck) received 50 Gy in 25 fractions over 5 weeks. Adjuvant chemotherapy was not administered.

    Daily vitamin D in addition to calcium supplementation reduces falls and fractures in older women. However, poor adherence to therapy is a common clinical problem. To examine the effects of supervised oral 3-monthly vitamin D therapy on falls, muscle strength, and mobility, we conducted a 9-month randomized, double-blind, placebo-controlled trial in 686 community-dwelling ambulant women aged over 70 years. Participants received either oral cholecalciferol 150,000 IU every 3 months (n = 353) or an identical placebo (n = 333). All participants were advised to increase dietary calcium intake. Falls data were collected 3-monthly. At baseline, 3, 6, and 9 months, muscle strength was measured by a handheld dynamometer and mobility by the Timed Up and Go (TUG) test. Serum 25 hydroxyvitamin D (25OHD) was measured in a subgroup of 40 subjects. Mean age at baseline was 76.7 ± 4.1 years. The average serum 25OHD value at baseline was 65.8 ± 22.7 nmol/L. By 3, 6, and 9 months after supplementation, 25OHD levels of the vitamin D group were approximately 15 nmol/L higher than the placebo group. Calcium intake did not change significantly between baseline (864 ± 412 mg/day) and 9 months (855 ± 357 mg/day). Faller rates in the two groups did not differ: vitamin D group, 102 of 353 (29%); placebo group, 89 of 333 (27%). At 9 months, compared to placebo or baseline, muscle strength, and TUG were not altered by vitamin D. In conclusion, oral cholecalciferol 150,000 IU therapy administered 3-monthly had neither beneficial nor adverse effects on falls or physical function. These data together with previous findings confirm that intermittent large doses of vitamin D are ineffective or have a deleterious effect on falls. Thus despite adherence issues with daily vitamin D replacement, an intermittent, high-dose vitamin D regimen cannot be supported as a strategy to reduce falls and fractures.

    The study aimed to examine the effects that L-glutamine supplementation has on quadriceps muscle strength and soreness ratings following eccentric exercise. It was hypothesized that glutamine ingestion would quicken the recovery rate of peak force production and decrease muscle soreness ratings over a 72-hr recovery period. Sixteen healthy participants (8♀/8♂; 22 ± 4 years) volunteered in a double-blind, randomized, placebo-controlled crossover study. Supplement conditions consisted of isoenergetic placebo (maltodextrin, 0.6 g·kg-1·day-1) and L-glutamine (0.3 g·kg-1·day-1 + 0.3 g·kg-1·day-1 maltodextrin) ingestion once per day over 72 hr. Knee extensor peak torque at 0°, 30°, and 180° per second and muscle soreness were measured before, immediately following, 24, 48, and 72 hr posteccentric exercise. Eccentric exercise consisted of 8 sets (10 repetitions/set) of unilateral knee extension at 125% maximum concentric force with 2-min rest intervals. L-glutamine resulted in greater relative peak torque at 180°/sec both immediately after (71 ± 8% vs. 66 ± 9%), and 72 hr (91 ± 8% vs. 86 ± 7%) postexercise (all, p eccentric exercise. The effect of L-glutamine on muscle force recovery may be greater in men than women.

    In Ethiopia, knowledge of contraceptive methods is high though there is low contraceptive prevalence rate. This study was aimed to assess prevalence and associated factors of long acting and permanent contraceptive methods in Jinka town, southern Ethiopia. Community based cross sectional survey was conducted to assess the prevalence and factors affecting long acting and permanent methods of contraceptives utilization from March to April 2008. Eight hundred child bearing age women were participated in the quantitative study and 32 purposively selected focus group discussants were participated in the qualitative study. Face to face interview was used for data collection. Data were analyzed by SPSS version 13.0 statistical software. Descriptive statistics and logistic regression were computed to analyze the data. The prevalence of long acting and permanent contraceptive method was 7.3%. Three fourth (76.1%) of the women have ever heard about implants and implant 28 (50%) were the most widely used method. Almost two third of women had intention to use long acting and permanent methods. Knowledge of contraceptive and age of women have significant association with the use of long acting and permanent contraceptive methods. The overall prevalence of long acting and permanent contraceptive method was low. Knowledge of contraceptive and age of women have significant association with use of long acting and permanent contraceptive. Extensive health information should be provided.

    ZYDPLA1 is a long acting enzyme dipeptidyl peptidase-4 (DPP-4) inhibitor. The comparative effect of DPP-4 inhibition after intravenous (IV) and oral administration of ZYDPLA1 in a rat model was evaluated to answer the question of route dependency and/or the need of high plasma levels of ZYDPLA1. The study was conducted using parallel design in male Wistar rats for IV/oral route (n=9 and 6, for IV and oral respectively). A single 30 mg/kg dose of ZYDPLA1 was administered. Plasma samples were analysed for ZYDPLA1 concentration and DPP-4 inhibition. Pharmacokinetic analysis was carried out to assess peak concentration, area under the concentration-time curve, total body clearance, elimination half-life, and mean residence time. The PK/PD correlation was performed using standard sigmoidal Emax modelling to derive; maximum effect (Emax) and concentration to exert 50% Emax effect (EC50). ZYDPLA1 showed rapid absorption, high volume of distribution, low clearance, and complete oral bioavailability. The Emax derived after both routes and corresponding PK/PD profile showed comparable DDP-4 inhibition. The EC50 for IV (0.021 µg/mL) was comparable to the oral route (0.019 µg/mL). ZYDPLA1 showed full DPP-4 inhibition without regard to the route of administration. Higher systemic peak levels showed no bearing on the DDP-4 inhibition. © Georg Thieme Verlag KG Stuttgart · New York.

    We have treated 16 acromegalic patients for up to 44 months with octreotide in varying doses. Growth hormone levels were suppressed in 14 patients with associated clinical improvement. IGF-1 levels were measured in 12 and fell into the normal range in 10. Prolactin was suppressed in six hyperprolactinaemic patients but was unaltered in normoprolactinaemic acromegalic patients. Post-prandial hyperglycaemia with impaired insulin secretion was noted in all patients, and one patient required oral hypoglycaemic agents. Octreotide did not affect thyroid function. CT scans from before and after six months of treatment demonstrated minimal tumour shrinkage in only two patients. Octreotide was well tolerated with no serious haematological or biochemical disturbance and no evidence of malabsorption. Two patients developed gallstones. Octreotide is effective in acromegaly. The development of gallstones is the only serious adverse event we have encountered.

    Chronic obstructive pulmonary disease (COPD), a largely preventable and manageable respiratory condition, affects an estimated 12% to 20% of adults. Long-acting inhaled β-agonists and anticholinergics have both been shown to improve COPD outcomes and are recommended for moderate to severe disease; however, little is known about their comparative effectiveness. To compare survival in older patients with COPD who initially receive inhaled long-acting β-agonists with that of patients who receive anticholinergics. Population-based, retrospective cohort study. Ontario, Canada. Patients aged 66 years or older (who carry the largest burden of COPD and for whom data were available) who met a validated case definition of COPD on the basis of health administrative data and were newly prescribed an inhaled long-acting β-agonist or a long-acting anticholinergic (but not both) between 2003 and 2007. Patients were followed for up to 5.5 years. The primary outcome was all-cause mortality. A total of 46 403 patients with COPD (mean age, 77 years; 49% women) were included. Overall mortality was 38.2%. Mortality was higher in patients initially prescribed a long-acting anticholinergic than in those initially prescribed a long-acting inhaled β-agonist (adjusted hazard ratio, 1.14 [95% CI, 1.09 to 1.19]). Rates of hospitalizations and emergency department visits were also higher in those initially prescribed a long-acting anticholinergic. Patients were classified as having COPD on the basis of health administrative records, which did not contain information about lung function. Older adults initially prescribed long-acting inhaled β-agonists for the management of moderate COPD seem to have lower mortality than those initially prescribed long-acting anticholinergics. Further research is needed to confirm these findings in younger patients and in a randomized, controlled trial. Government of Ontario, Canada.

    Full Text Available OBJECTIVE: The aim of this study was to assess the presence of oral myofunctional alterations before and after first premolar extraction in Class II/1 malocclusion patients that could endanger the long-term dental arch stability. MATERIAL AND METHODS: The study was performed by means of morphological, functional and electromyographic analyses in 17 Class II/1 malocclusion patients (group T and 17 Class I malocclusion patients (group C -control, both groups with 12-30-year age range (mean age: 20.93 ± 4.94 years. RESULTS: Data analyzed statistically by Student's t-test showed a significant decrease (p0.05. The Kruskal-Wallis test analyzed data from lip posture (orbicularis oris muscle at rest and during swallowing, as well as the mentalis muscle behavior during the above-mentioned function, not showing statistically significant differences (p>0.05 after treatment (groups T1 and T2. However, group T differed significantly from group C (p<0.05. Lip posture during swallowing showed statistically significant differences (p<0.05 for subjects submitted to orthodontic therapy when compared to data acquired before the treatment. The electromyographic analysis confirmed these data. CONCLUSIONS: Found myofunctional alterations observed after the orthodontic treatment in Class II/1 malocclusion seemed to jeopardize the long-term orthodontic stability, making recurrence possible.

    Introduction Opioid-related mortality appears to be increasing in Canada. We examined the true extent of the problem and the impact of the introduction of long-acting oxycodone. Methods We examined trends in the prescribing of opioid analgesics in the province of Ontario from 1991 to 2007. We reviewed all deaths related to opioid use between 1991 and 2004. We linked 3271 of these deaths to administrative data to examine the patients’ use of health care services before death. Using time-series analysis, we determined whether the addition of long-acting oxycodone to the provincial drug formulary in January 2000 was associated with an increase in opioid-related mortality. Results From 1991 to 2007, annual prescriptions for opioids increased from 458 to 591 per 1000 individuals. Opioid-related deaths doubled, from 13.7 per million in 1991 to 27.2 per million in 2004. Prescriptions of oxycodone increased by 850% between 1991 and 2007. The addition of long-acting oxycodone to the drug formulary was associated with a 5-fold increase in oxycodone-related mortality (p opioid-related mortality (p = 0.02). The manner of death was deemed unintentional by the coroner in 54.2% and undetermined in 21.9% of cases. Use of health care services in the month before death was common: for example, of the 3066 patients for whom data on physician visits were available, 66.4% had visited a physician in the month before death; of the 1095 patients for whom individual-level prescribing data were available, 56.1% had filled a prescription for an opioid in the month before death. Interpretation Opioid-related deaths in Ontario have increased markedly since 1991. A significant portion of the increase was associated with the addition of long-acting oxycodone to the provincial drug formulary. Most of the deaths were deemed unintentional. The frequency of visits to a physician and prescriptions for opioids in the month before death suggests a missed opportunity for prevention. PMID:19969578

    Fourteen patients with metastatic pancreatic adenocarcinoma were treated with the long-acting somatostatin (SST) analogue lanreotide. No objective response was obtained, and the median survival was 4 months (range 1.8–7 months). Pancreatic cancer could not be visualized by means of SST-receptor (R) scintigraphy in our patients. In vitro data also demonstrated absence of SSTR2 expression, suggesting pancreatic cancer not to be a potential target for treatment with SST analogues. © 1999 Cancer Research Campaign PMID:10027326

    After decades of having the developed world's highest rates of unintended pregnancy, the United States finally shows signs of improvement. This progress is likely due in large part to increased use of highly effective long-acting reversible methods of contraception. These methods can be placed and do not require any maintenance to provide years of contraception as effective as sterilization. Upon removal, fertility returns to baseline rates. This article addresses advances in both software-improved use and elimination of barriers to provide these methods; and hardware-novel delivery systems and devices.

    Antidiabetic treatments aiming to reduce body weight are currently gaining increased interest. Exendin-4, a glucagon-like peptide-1 (GLP-1) receptor agonist administered twice daily via s.c. injection, improves glycemic control, often with associated weight reduction. To further improve the therapeutic efficacy of exendin-4, we have developed a novel peptide engineering strategy that incorporates a serum protein binding motif onto a covalent side-chain staple and applied to the peptide to enhance its helicity and, as a consequence, its potency and serum half-life. We demonstrated that one of the resulting peptides, E6, has significantly improved half-life and glucose tolerance in an oral glucose tolerance test in rodents. Chronic treatment of E6 significantly decreased body weight and fasting blood glucose, improved lipid metabolism, and also reduced hepatic steatosis in diet-induced obese mice. Moreover, the high potency of E6 allowed us to administer this peptide using a dissolvable microstructure-based transdermal delivery system. Pharmacokinetic and pharmacodynamic studies in guinea pigs showed that a single 5-min application of a microstructure system containing E6 significantly improved glucose tolerance for 96 h. This delivery strategy may offer an effective and patient-friendly alternative to currently marketed GLP-1 injectables and can likely be extended to other peptide hormones.

    Severe long-term complaints of dumping occur in a small number of patients after gastric surgery. Dietary modification, fiber preparations, and medical therapy are often ineffective. In these severely affected patients administration of the somatostatin analog octreotide before meals appears to be a promising new strategy. The effects of octreotide on both gastrointestinal transit time and hormonal changes appear to contribute to the benefits seen in dumping syndrome. However, as the majority of studies conducted have employed only a single dose of octreotide, careful long-term assessment of the nutritional and metabolic effects will be required. Recent results suggest that octreotide may be administered up to 2 hr before a meal and therefore has a sufficiently long duration of action to be of practical long-term use. Moreover, general improvements in life-style, as well as beneficial effects on symptoms, have been reported with long-term treatment, although the potential development of diarrhea will require careful monitoring. The development of an oral or nasal formulation should further improve the practical application of octreotide as a treatment for dumping syndrome.

    Strategic supplementation of P4 may be used to increase conception rates in cattle, but timing of supplementation in relation to ovulation, mass of supplementary P4 and formulation of the P4-containing supplement has not been determined for beef cattle. Effects of supplementation of long-acting progesterone (P4) on Days 2 or 3 post-ovulation on development, function and regression of corpus luteum (CL) were studied in beef cattle. Cows were synchronized with an oestradiol/P4-based protocol and treated with 150 or 300 mg of long-acting P4 on Day 2 or 3 post-ovulation (6-7 cows/group). Colour-doppler ultrasound scanning and blood sample collection were performed from Day 2-21.5. Plasma P4 concentrations were greater (p  0.05) among groups, suggesting no effect of P4 treatment on luteal development. The frequency of cows that began luteolysis before Day 15 was greater (p beef cattle. © 2013 Blackwell Verlag GmbH.

    Full Text Available Abstract Background The purpose of this analysis was to compare health care costs and utilization among COPD patients who had long-acting beta-2 agonist (LABA OR long-acting muscarinic antagonist (LAMA; LABA AND LAMA; or LABA, LAMA, AND inhaled corticosteroid (ICS prescription claims. Methods This was a 12 month pre-post, retrospective analysis using COPD patients in a national administrative insurance database. Propensity score and exact matching were used to match patients 1:1:1 between the LABA or LAMA (formoterol, salmeterol, or tiotropium, LABA and LAMA (tiotropium/formoterol or tiotropium/salmeterol, and LABA, LAMA and ICS (bronchodilators plus steroid groups. Post-period comparisons were evaluated with analysis of covariance. Costs were evaluated from a commercial payer perspective. Results A total of 523 patients were matched using 29 pre-period variables (e.g., demographics, medication exposure. Post-match assessments indicated balance among the cohorts. COPD-related costs differed among groups (LABA or LAMA $2,051 SE = 91; LABA and LAMA $2,823 SE = 62; LABA, LAMA and ICS $3,546 SE = 89; all p Conclusions Significant cost differences driven mainly by pharmaceuticals were observed among LABA or LAMA, LABA and LAMA and LABA, LAMA and ICS therapies. A COPD-related cost offset was observed from single bronchodilator to two bronchodilators. Addition of an ICS with two bronchodilators resulted in higher treatment costs without reduction in other COPD-related costs compared with two bronchodilators.

    In the latest report of Ethiopian Demographic and Health Survey (EDHS) 2011, the maternal mortality ratio (MMR) was estimated at 676/100,000 live births, with total fertility rate at 4.8 and contraceptive prevalence rate at 29 %. Knowledge and utilization of long acting contraceptive in the Tigray region are low. This study aims at comparing and identifying factors related to the utilization of long acting contraceptive in urban versus rural settings of Ethiopia. A comparative community-based cross-sectional study, comprised of quantitative and qualitative methods, was conducted among 1035 married women in Wukro (urban area) and Kilteawlaelo district (rural area) in March, 2013. Stratified sampling technique was employed to approach the study participants. Data were analyzed using SPSS version 20. Multiple logistic regression analysis was used to identify the respective effect of independent predictors on utilization of long acting contraceptive. The proportion of long acting contraceptive use among the respondents was 19.9 % in the town of Wukro and 37.8 % in the district of Kilteawlaelo. Implanon was the most common type of contraceptive used in both districts, urban (75 %) and rural (94 %). The odds of using the long acting contraceptive method were three times higher among married women in the rural areas as compared with the urban women [AOR = 3. 30; 95 %, CI:2.17, 5.04]. No or limited support from male partners was an obstacle to using long acting contraceptive method [AOR = 0. 24, 95 of CI: 0.13, 0.44]. Moreover, married women whose partner did not permit them to use long acting contraceptive [AOR = 0. 47, 95 % of CI: 0.24, 0.92] and women who attended primary education [AOR = 0.24, 95 %, CI: 0.13, 0.44] were significantly associated with long acting contraceptive use. Overall, the proportion of long acting contraceptive use has found to be low. Rural women were more likely to use long acting contraceptives as compared to urban women

    Demand for long acting contraceptive methods is one of the key factors for total fertility rate and reproductive health issues. Increased demand for these methods can decline fertility rate through spacing and limiting family size in turn improving maternal and family health and socioeconomic development of a country. The aim of this study was to assess demand for long acting contraceptives and associated factors among family planning users in Debre-Tabor Town, Northwest Ethiopia. Facility based cross-sectional study was conducted from July to August 2013. Data was collected on 487 current family planning users through face to face interview using structured questionnaire. Study participants were selected by systematic sampling method. Data were entered in to Epi Info and analyzed by using SPSS version 20. Bi-variable and multi-variable regression analyses were done to identify factors associated with demand for long acting contraceptive methods. Odds ratio with 95% CI was used to assess the association between the independent variables and demand for long acting family planning methods. The study showed that, demand for long acting contraceptives was 17%. Only 9.2% of the women were using long acting contraceptive methods (met need). About 7.8% of women were using short acting methods while they actually want to use long acting methods (unmet need). Demand for LACMs was positively associated 3 with being a daily labour (AOR = 3.87, 95% CI = [1.06, 14.20]), being a student (AOR = 2.64, 95% CI = [1.27, 5.47]), no future birth intensions (AOR = 2.17, 95% CI = [1.12, 4.23]), having five or more children (AOR = 1.67, 95% CI = [1.58, 4.83]), deciding together with husbands for using the methods (AOR = 2.73, 95% CI = [1.40, 5.32]) and often having discussion with husband (AOR = 3.89, 95% CI = [1.98, 7.65]). Clients treated poorly by the health care providers during taking the services was negatively associated with demand for LACMs (AOR = 0.42, 95% CI = [0.24, 0

  13. Expression and Characterization of a Potent Long-Acting GLP-1 Receptor Agonist, GLP-1-IgG2σ-Fc.

    Full Text Available Human GLP-1 (glucagon-like peptide-1 can produce a remarkable improvement in glycemic control in patients with type 2 diabetes. However, its clinical benefits are limited by its short half-life, which is less than 2 min because of its small size and rapid enzymatic inactivation by dipeptidyl peptidase IV. We engineered GLP-1-IgG2σ-Fc, a 68-kDa fusion protein linking a variant human GLP-1 (A8G/G26E/R36G to a human IgG2σ constant heavy-chain. A stably transfected Chinese hamster ovary cell line was obtained using electroporation. Western blotting showed that the expressed protein was immunoreactive to both GLP-1 and IgG antibodies. GLP-1-IgG2σ-Fc stimulated insulin secretion from INS-1 cells in a dose- and glucose-dependent manner and increased insulin mRNA expression. The half-life of GLP-1-IgG2σ-Fc in cynomolgus monkeys was approximately 57.1 ± 4.5 h. In the KKAy mouse model of diabetes, one intraperitoneal injection of GLP-1-IgG2σ-Fc (1 mg/kg reduced blood glucose levels for 5 days. A 4-week repeat-administration study identified sustained effects on blood glucose levels. Oral glucose tolerance tests conducted at the beginning and end of this 4-week period showed that GLP-1-IgG2σ-Fc produced a stable glucose lowering effect. In addition, KKAy mice treated with GLP-1-IgG2σ-Fc showed statistically significant weight loss from day 23. In conclusion, these properties of GLP-1-IgG2σ-Fc demonstrated that it represented a potential long-acting GLP-1 receptor agonist for the treatment of type 2 diabetes.

    Sarcopenia is an inevitable age-related degenerative process chiefly characterized by decreased synthesis of muscle proteins and impaired mitochondrial function, leading to progressive loss of muscle mass. Here, we sought to probe whether long-term administration of oral amino acids (AAs) can increase protein and adenosine triphosphate (ATP) content in the gastrocnemius muscle of aged rats, enhancing functional performance. To this end, 6- and 24-month-old male Fisher 344 rats were divided into 3 groups: group A (6-month-old rats) and group B (24-month-old rats) were used as adult and senescent control group, respectively, while group C (24-month-old rats) was used as senescent treated group and underwent 1-month oral treatment with a mixture of mainly essential AAs. Untreated senescent animals exhibited a 30% reduction in total and fractional protein content, as well as a 50% reduction in ATP content and production, compared with adult control rats (p supplementation with mixed AAs significantly improved protein and high-energy phosphate content, as well as the rate of mitochondrial ATP production, conforming their values to those of adult control animals (p energy substrates in the gastrocnemius muscle of treated aged rats paralleled a significant enhancement in functional performance assessed by swim test, with dramatic elongation of maximal exertion times compared with untreated senescent rats (p supplementation with oral AAs improved protein and energy profiles in the gastrocnemius of treated rats, enhancing functional performance and accelerating high-energy phosphate recovery after exhaustive exertion.

    2016-01-01

    Much has been written about the consequences of substance use in pregnancy, but there has been far less focus on the prevention of unintended pregnancies in women with substance use disorders (SUDs). We examine the literature on pregnancy incidence for women with SUDs, the clinical and economic benefits of increasing access to long-acting reversible contraceptive (LARC) methods in this population, and the current hurdles to increased access and uptake. High rates of unintended pregnancies and poor physical and psychosocial outcomes among women with SUDs underscore the need for increased access to, and uptake of, LARC methods among these women. A small number of studies that focused on improving access to contraception, especially LARC, via integrated contraception services predominantly provided in drug treatment programs were identified. However, a number of barriers remain, highlighting that much more research is needed in this area.

    We investigated a method to quantitatively determine amorphous nicardipine hydrochloride (NIC) in the NIC-long acting formula (LA) model formulas prepared using NIC, light anhydrous silicic acid (LASA) and carboxymethylethylcellulose (CMEC). Consequently, since the quantity of total NIC in the formula can be determined by means of HPLC and crystal NIC can be determined by the differential scanning calorimetry (DSC) method because the heat of fusion (85.08 J/g) of NIC is constant and unaffected by excipients, we developed the HPLC-DSC method by which the quantity of amorphous NIC is calculated as the difference between the quantity of total NIC determined by HPLC and the quantity of crystal NIC determined by DSC. This practical HPLC-DSC method was confirmed to have good accuracy and reproducibility.

    The objective of this study was to investigate the pharmacokinetics of a long-acting fentanyl solution in helmeted guineafowl ( Numida meleagris ) after transdermal administration. Twenty-one guineafowl received a single administration of 5 mg/kg of fentanyl transdermal solution. No adverse effects on behavior were appreciated. Plasma fentanyl concentrations were determined by liquid chromatography-mass spectrometry analysis of protein-precipitated samples. Mean maximum plasma concentration was 228.8 ng/ml at 4 hr. The mean plasma terminal half-life was 33.2 hr. At 168 hr the mean plasma concentration was 1.3 ng/ml. A single topical dose of 5 mg/kg appears to be safe for use in this species and maintained plasma concentrations above those reported to be analgesic in dogs for at least 7 days.

    To evaluate whether contraceptive insurance coverage for women who present for an abortion is associated with obtaining long-acting reversible contraception or depot medroxyprogesterone acetate (DMPA) on the day the abortion is completed. We conducted a prospective cohort study of women presenting for medical or surgical abortion at a single health center in North Carolina. Eligible women were 18 years or older and fluent in English or Spanish. Data were from participant questionnaires, medical charts, and financial records. Our main exposure was whether the woman had insurance coverage for contraception at clinic intake. Our primary outcome was receiving DMPA, an intrauterine device, or a contraceptive subdermal implant on the same day of their surgical abortion or at the visit that determined their medication abortion was complete. We used univariable, bivariable, and multivariable analysis to report our findings. Five hundred seventy-five women enrolled in our cohort between September 2015 and April 2016. One hundred twenty-eight (22%) had insurance coverage and 447 (78%) did not. In the group with insurance coverage for contraception, 38% (49/128) received a long-acting reversible contraception method or DMPA compared with 7% (33/447) in the group without insurance coverage for contraception. After adjusting for confounding, women with contraceptive coverage were more than five times as likely to receive immediate postabortion contraception with one of these methods compared with women without coverage (relative risk 5.6, 95% confidence interval 3.8-8.3). Women with contraceptive insurance coverage on the day of their abortion were more likely to leave the abortion clinic with an intrauterine device or implant in place or receive DMPA injection compared with women without coverage.

    The efficacy of combined treatment in active acromegaly with both long-acting somatostatin analogs (SRIF) and pegvisomant (PEG-V) has been well established. The aim was to describe the PEG-V dose reductions after the conversion from daily PEG-V to combination treatment. To clarify the individual beneficial and adverse effects, in two acromegaly patients, who only normalized their insulin like growth factor (IGF-I) levels with high-dose pegvisomant therapy. We present two cases of a 31 and 44 years old male with gigantism and acromegaly that were controlled subsequently by surgery, radiotherapy, SRIF analogs and daily PEG-V treatment. They were converted to combined treatment of monthly SSA and (twice) weekly PEG-V. High dose SSA treatment was added while the PEG-V dose was decreased during carful monitoring of the IGF-I. After switching from PEG-V monotherapy to SRIF analogs plus pegvisomant combination therapy IGF-I remained normal. However, the necessary PEG-V dose, to normalize IGF-I differed significantly between these two patients. One patient needed twice weekly 100 mg, the second needed 60 mg once weekly on top of their monthly lanreotide Autosolution injections of 120 mg. The weekly dose reduction was 80 and 150 mg. After the introducing of lanreotide, fasting glucose and glycosylated haemoglobin concentrations increased. Diabetic medication had to be introduced or increased. No changes in liver tests or in pituitary adenoma size were observed. In these two patients, PEG-V in combination with long-acting SRIF analogs was as effective as PEG-V monotherapy in normalizing IGF-I levels, although significant dose-reductions in PEG-V could be achieved. However, there seems to be a wide variation in the reduction of PEG-V dose, which can be obtained after conversion to combined treatment.

    Long-acting neuroleptics commonly are used in wildlife management to decrease stress-related mortality in wild animals, but with possible effects on thermoregulation, which may contribute to residual morbidity and mortality. We investigated the effects of haloperidol (0.01, 0.1, 1 mg kg(-1), n=4), zuclopenthixol (0.1, 1, 10 mg kg(-1), n=4) and perphenazine (0.1, 1, 10 mg kg(-1), n=8), as well as control injections of sunflower oil, on body temperature and physical activity of laboratory goats under hot, cold and thermoneutral ambient temperatures. Implanted data loggers continuously recorded abdominal temperature, and data loggers attached externally on the foreleg recorded movement of unrestrained goats, in a climatic chamber at 35 degrees C, 10 degrees C and 22 degrees C. Cycling ambient temperature between 35 degrees C in daytime and 10 degrees C at night time caused a significant increase in amplitude of the circadian rhythm of body temperature in goats given sunflower oil (P=0.0012, unpaired t-test, n=8), but the administration of zuclopenthixol or perphenazine did not affect this change in amplitude (P>0.05, two-way ANOVA, n=4). Mean daily body temperature after administration of zuclopenthixol or perphenazine, and mean daily activity after zuclopenthixol administration, were not significantly different to those after control injections, at any ambient temperature, for the expected duration of drug activity (all P>0.05, two-way ANOVA, n=4). Thermal response indices, and mean activity, during heat, cold or thermoneutral exposure, of goats for 7 h after haloperidol injection, were not significantly different, at any dose or any ambient temperature, to those following control injections (all P>0.05, repeated measures ANOVA, n=4). Long-acting neuroleptics did not impair activity or thermoregulation of goats subjected to inescapable thermal challenges.

    Measures of contraceptive effectiveness combine technology and user-related factors. Observational studies show higher effectiveness of long-acting reversible contraception compared with short-acting reversible contraception. Women who choose long-acting reversible contraception may differ in key ways from women who choose short-acting reversible contraception, and it may be these differences that are responsible for the high effectiveness of long-acting reversible contraception. Wider use of long-acting reversible contraception is recommended, but scientific evidence of acceptability and successful use is lacking in a population that typically opts for short-acting methods. The objective of the study was to reduce bias in measuring contraceptive effectiveness and better isolate the independent role that long-acting reversible contraception has in preventing unintended pregnancy relative to short-acting reversible contraception. We conducted a partially randomized patient preference trial and recruited women aged 18-29 years who were seeking a short-acting method (pills or injectable). Participants who agreed to randomization were assigned to 1 of 2 categories: long-acting reversible contraception or short-acting reversible contraception. Women who declined randomization but agreed to follow-up in the observational cohort chose their preferred method. Under randomization, participants chose a specific method in the category and received it for free, whereas participants in the preference cohort paid for the contraception in their usual fashion. Participants were followed up prospectively to measure primary outcomes of method continuation and unintended pregnancy at 12 months. Kaplan-Meier techniques were used to estimate method continuation probabilities. Intent-to-treat principles were applied after method initiation for comparing incidence of unintended pregnancy. We also measured acceptability in terms of level of happiness with the products. Of the 916

    Full Text Available The aim of this work was to prepare the mares for embryo transfer. In group 1 (G1,treated, n=15, recipient mares in anoestrus or in a transition period were treated with 5.0, 3.0 and 2.0 mg of estradiol cipionate at the days 0, 1 and 2 respectively, beginning at the day of ovulation (DO. From the fourth day on, the mares this group received long-acting progesterone weekly, up to the 120 day of gestation. At D8, the embryo was collected from the donor and transferred to the recipient. At D12, the ultrasonographyc diagnosis of pregnancy was carried out. The control group (G2, not treated, n=20 was formed by cycling recipient mares, displaying ovulation at each 2 to 3 days after the donors mare ovulation. The pregnancy rate was higher (p<0.05 in the mares from G2 (85.0% than from G1 (53.3%. Thus, it could be concluded that the treated mares although showed lesser pregnancy rate than the cycling mare, were satisfactory alternative to be used mainly when there is no available cycling recipient.

    The objective of this study was to prepare the nanocrystals of curcumin didecanoate (CurDD) by wet ball milling and to investigate the comparative pharmacokinetics of oily nano- and micro-suspensions after intramuscular (i.m.) administration to rats. Upon optimizing the wet ball milling parameters, CurDD nanocrystals were produced with median particle size of ~500 nm and the freeze-dried nanocrystals were readily dispersed in peanut oil to form stable nanosuspensions. Although the nanosuspension appeared to exhibit slower clearance from the injection site after i.m. injection, compared to microsuspension (~5 μm), a significantly higher maximum plasma curcumin concentration (69.0 ng/ml) was observed for the former than that for the latter (18.5 ng/ml). In addition, the nanosuspension provided significant higher plasma curcumin concentrations and brain CurDD contents for at least 15 days than the microsuspension, except for the initial times. A single i.m. injection of nanosuspension appeared to achieve reversal effect on reserpine-induced hypothermia for at least 13 days. This study demonstrates that CurDD nanosuspension may act as a long-acting i.m. injectable for sustained delivery of curcumin, potentially applicable to elicit a long-lasting antidepressant effect.

    Here, we discuss certain practical issues related to use of insulin degludec, a new long-acting basal insulin analogue. Degludec provides uniform ("peakless") action that extends over more than 24 hours and is highly consistent from dose to dose. Like the 2 previously available basal analogues (detemir and glargine), degludec is expected to simplify dose adjustment and enable patients to reach their glycemic targets with reduced risk of hypoglycemia. Phase 3 clinical trials involving type 1 and type 2 diabetes have demonstrated that degludec was noninferior to glargine in allowing patients to reach a target glycated hemoglobin (A1C) of 7%, and nocturnal hypoglycemia occurred significantly less frequently with degludec. In addition, when dosing intervals vary substantially from day to day, degludec continues to be effective and to maintain a low rate of nocturnal hypoglycemia. Degludec thus has the potential to reduce risk of nocturnal hypoglycemia, to enhance the flexibility of the dosing schedule and to improve patient and caregiver confidence in the stability of glycemic control. A dedicated injector, the FlexTouch prefilled pen, containing degludec 200 units/mL, will be recommended for most patients with type 2 diabetes. Degludec will also be available as 100 units/mL cartridges, to be used in the NovoPen 4 by patients requiring smaller basal insulin doses, including most patients with type 1 diabetes.

    The effect of the long acting calcium channel blocker, barnidipine hydrochloride (barnidipine) on 24-h ambulatory blood pressure (ABP) was evaluated in J-MUBA (Japanese Multicentre Study on Barnidipine with Ambulatory Blood Pressure Monitoring). Following an observation period of two weeks, antihypertensive treatment with barnidipine was continued for at least six months. At the end of each period, ABP were measured. The patients were divided into high- and low-range groups based on ABP measurement. Throughout the 24 h, barnidipine exerted an excellent antihypertensive effect in the high-range group, but not in the low-range group. Barnidipine had comparable effects in the daytime and nighttime in inverted dippers and non-dippers, but it was more effective on daytime ABP than on nighttime ABP in dippers and in extreme dippers. Morning blood pressure before and after waking was evaluated before and after barnidipine administration in 233 patients. Barnidipine inhibited increases in blood pressure before and after waking, especially in surge-type patients whose blood pressure increased rapidly after waking. A positive correlation among 24-h ABP, daytime and night time ABP, morning blood pressure, and clinic blood pressure during the observation period and the antihypertensive effect of barnidipine was observed, with barnidipine exhibiting stronger antihypertensive effects in patients with persistently high blood pressure. It was concluded that the antihypertensive effects of barnidipine are maintained for 24 h but it has no excessive hypotensive effects on lower blood pressure and is thus a safe antihypertensive agent.

    Full Text Available Growing interest had been focused on the involvement of the small airways in asthma, and impulse oscillometry (IOS has been utilized as pulmonary functions for detecting large and small airways diseases separately. IOS can measure respiratory resistance and reactance at multiple frequencies, not available by spirometry or body plethysmography, is non-invasive techniques and convenient for elderly patients with a low dependency on cooperation during tidal breathing. IOS indices were well correlated with not only predicted FEV1 but also FEF25-75, residual volume/total lung capacity, delta N2 of a single nitrogen washout test which representing air trapping and inhomogeneous ventilation in the distal lung. These parameters and QOL scores were improved by additional transdermal long-acting beta-2 agonist patch even in well-controlled elderly asthma treating with inhaled corticosteoids alone. IOS may have a complementary role of spirometry in detecting subtle airways changes in general practice. However, systemic studies are required to investigate the clinical implication of each IOS index.

    Objective To investigate whether somatostatin analog octreotide long acting release (LAR) shrinks growth hormone (GH) secreting adenomas, and improves the results of subsequent transsphenoidal surgery.Methods Seventeen previously untreated active acromegalic patients with pituitary adenomas were treated with LAR (30 mg intramuscular injection every 28 days) for 3 months prior to transsphenoidal surgery. Clinical reaction, mean GH secretion, and tumor volume were measured under basal conditions and after LAR treatment.Results Presurgical treatment improved acromegaly symptoms and induced a significant reduction of GH under the 5 ng/mL limit in microadenoma (P < 0.05), while only 18.2% (2/11) in macroadenoma. Meanwhile, tumor shrinkage occurred in 58.8% (10/17) patients, with 1 case in the microadenoma group. All marked shrinkage (> 25%) occurred in the macroadenoma group. Statistical analysis showed tumor shrinkage caused by LAR was greater in macroadenoma group than that in microadenoma group (P < 0.05). During operation, adenoma was soft in 15 cases, with the exception of 2cases in which the soft rumor was divided by fibrous septa, but all tumor removal was smooth.Conclusions A short term administration of preoperative LAR may induce a significant decrease in GH-secretion level and adenoma volume. Presurgical use of octreotide LAR improves surgical results especially in macroadenomas.

    US women Veterans are at increased risk of homelessness and chronic health conditions associated with unintended pregnancy. Veterans Health Administration (VHA) provision of long-acting reversible contraception (LARC) can assist in healthy pregnancy planning. To evaluate perinatal risk factors and LARC exposure in ever-homeless women Veterans. A retrospective cohort study of women Veterans using VHA administrative data from fiscal years 2002-2015. We included 41,747 ever-homeless women Veterans age 18-44 years and 46,391 housed women Veterans matched by military service period. A subgroup of 7773 ever-homeless and 8674 matched housed women Veterans deployed in Iraq and Afghanistan [Operations Enduring Freedom/Iraqi Freedom/New Dawn (OEF/OIF/OND)] conflicts comprised a second analytic cohort. Descriptive statistics compared demographic, military, health conditions, and LARC exposure in ever-homeless versus housed women Veterans. Multivariable logistic regression explored factors associated with LARC exposure in the OEF/OIF/OND subgroup. All health conditions were significantly higher in ever-homeless versus housed Veterans: mental health disorder in 84.5% versus 48.7% (Phomeless women Veterans and providing LARC access. The prevalence of perinatal risk factors in ever-homeless women Veterans highlights a need for further programmatic enhancements to improve reproductive planning.

    Objective: To study the effects of three types of contraceptive implants: the domestic No I , No I implants and Norplant on menstrual blood loss (MBL). Method: Eighty-nine healthy subjects were randomly allocated to three groups.Menstrual blood loss was measured before implanting and 3, 6, and 12 months after implantation. Results: MBL of the three groups prior to the use of implant were 43. 3±6. 9ml,48.9±4. 3 ml, and 43.7±5. 5ml respectively, and decreased significantly at all post-implantation periods. MBLs were 32. 8±13. 2ml, 24. 8±5. 5ml, and 19. 7±9.3ml at the 3rd month after implantation and 23. 9±5. 9 ml, 40. 8±10. 4 ml, 25. 9±6. 0 ml at the 12th month after implantation respectively, sigmficantly less than before implantation(P<0. 05~0. 01). A tendency was seen in increase of hemoglobin concentraition. Conclusion: Long-acting contraceptive implants decreased menstrual blood loss and elevates hemoglobin concentration. They are applicable to women as a contraceptive method without blood loss effects.

    OBJECTIVES To develop and validate algorithms to identify new users of long-acting reversible contraceptives (LARCs) in a primary care database, The Health Improvement Network (THIN). METHODS Women in THIN aged 12 to 49 years in 2005 were studied. THIN was searched using Read and MULTILEX codes to identify new users of copper intrauterine devices (Cu-IUDs), the levonorgestrel-releasing intrauterine system (LNG-IUS) and progestogen-only implants. Validation was undertaken for a randomly selected sample of 398 LARC users, in which their primary care physicians were asked to complete a questionnaire detailing LARC use. RESULTS Questionnaires were received for 379 patients (95%), confirming 316 (83%) as new LARC users. Confirmation rates for Cu-IUDs, the LNG-IUS and progestogen-only implants were 64%, 94% and 89%, respectively. The use of Read codes alone had the lowest confirmation rate, particularly for Cu-IUD users. Confirmation rates increased by using MULTILEX codes when available, or by examination of computerised medical records. CONCLUSIONS Computer algorithms were used to identify new LARC users. While THIN is a useful resource for studying LARC uptake, steps to gather additional information are necessary to ensure the validity of LARC classification.

    Full Text Available Abstract Background Paliperidone palmitate is a long-acting injectable atypical antipsychotic for the acute and maintenance treatment of adults with schizophrenia. The recommended initiation dosing regimen is 234 mg on Day 1 and 156 mg on Day 8 via intramuscular (deltoid injection; followed by 39 to 234 mg once-monthly thereafter (deltoid or gluteal. These post-hoc analyses addressed two commonly encountered clinical issues regarding the initiation dosing: the time to onset of efficacy and the associated tolerability.

    Human studies suggest that chromium picolinate (CrPic) decreases insulin levels and improves glucose disposal in obese and type 2 diabetic populations. To evaluate whether CrPic may aid in treatment of the insulin resistance syndrome, we assessed its effects in JCR:LA-corpulent rats, a model of this syndrome. Male lean and obese hyperinsulinemic rats were randomly assigned to receive oral CrPic [80 microg/(kg. d); n = 5 or 6, respectively) in water or to control conditions (water, n = 5). After 3 mo, a 120-min intraperitoneal glucose tolerance test (IPGTT) and a 30-min insulin tolerance test were performed. Obese rats administered CrPic had significantly lower fasting insulin levels (1848 +/- 102 vs. 2688 +/- 234 pmol/L; P < 0.001; mean +/- SEM) and significantly improved glucose disappearance (P < 0.001) compared with obese controls. Glucose and insulin areas under the curve for IPGTT were significantly less for obese CrPic-treated rats than in obese controls (P < 0.001). Obese CrPic-treated rats had lower plasma total cholesterol (3.57 +/- 0.28 vs. 4.11 +/- 0.47 mmol/L, P < 0.05) and higher HDL cholesterol levels (1.92 +/- 0.09 vs. 1.37 +/- 0.36 mmol/L, P < 0.01) than obese controls. CrPic did not alter plasma glucose or cholesterol levels in lean rats. Total skeletal muscle glucose transporter (Glut)-4 did not differ among groups; however, CrPic significantly enhanced membrane-associated Glut-4 in obese rats after insulin stimulation. Thus, CrPic supplementation enhances insulin sensitivity and glucose disappearance, and improves lipids in male obese hyperinsulinemic JCR:LA-corpulent rats.

    Possibly. Long-acting β-2 agonists (LABAs) used in combination with inhaled corticosteroids (ICS) don't appear to increase all-cause mortality or serious adverse events in patients with persistent asthma compared with ICS alone. Studies showing an increase in catastrophic events had serious methodologic issues. A large surveillance study is ongoing.

    Despite the elevated rates of teen and unplanned pregnancies across the United States, long-acting reversible contraceptives (LARCs) remain a less utilized birth control method. The present study investigated family planning providers' attitudes and considerations when recommending family planning methods and LARCs to clients. Additionally, this study explored whether urban-rural differences exist in providers' attitudes toward LARCs and in clients' use of LARCs. Data were collected using an online survey of family planning providers at Title X clinics in Texas. Survey data was linked to family planning client data from the Family Planning Annual Report (2008). Findings indicated that, although providers were aware of the advantages of LARCs, clients' LARC use remains infrequent. Providers reported that the benefits of hormone implants include their effectiveness for 3 years and that they are an option for women who cannot take estrogen-based birth control. Providers acknowledged the benefits of several types of LARCs; however, urban providers were more likely to acknowledge the benefits of hormone implants compared with their rural counterparts. Results also indicated barriers to recommending LARCs, such as providers' misinformation about LARCs and their caution in recommending LARCs to adolescents. However, findings also indicated providers lack training in LARC insertion, specifically among those practicing in rural areas. In light of the effectiveness and longevity of LARCs, teenagers and clients living in rural areas are ideal LARC candidates. Increased training among family planning providers, especially for those practicing in rural areas, may increase their recommendations of LARCs to clients. Copyright © 2012 Jacobs Institute of Women

    Full Text Available TransCon growth hormone is a sustained-release human growth hormone prodrug under development in which unmodified growth hormone is transiently linked to a carrier molecule. It is intended as an alternative to daily growth hormone in the treatment of growth hormone deficiency. This was a multi-center, randomized, open-label, active-controlled trial designed to compare the safety (including tolerability and immunogenicity, pharmacokinetics and pharmacodynamics of three doses of weekly TransCon GH to daily growth hormone (Omnitrope. Thirty-seven adult males and females diagnosed with adult growth hormone deficiency and stable on growth hormone replacement therapy for at least 3 months were, following a wash-out period, randomized (regardless of their pre-study dose to one of three TransCon GH doses (0.02, 0.04 and 0.08 mg GH/kg/week or Omnitrope 0.04 mg GH/kg/week (divided into 7 equal daily doses for 4 weeks. Main outcomes evaluated were adverse events, immunogenicity and growth hormone and insulin-like growth factor 1 levels. TransCon GH was well tolerated; fatigue and headache were the most frequent drug-related adverse events and reported in all groups. No lipoatrophy or nodule formation was reported. No anti-growth hormone-binding antibodies were detected. TransCon GH demonstrated a linear, dose-dependent increase in growth hormone exposure without accumulation. Growth hormone maximum serum concentration and insulin-like growth factor 1 exposure were similar after TransCon GH or Omnitrope administered at comparable doses. The results suggest that long-acting TransCon GH has a profile similar to daily growth hormone but with a more convenient dosing regimen. These findings support further TransCon GH development.

    Recombinant factor IX Fc (rFIXFc) fusion protein is the first of a new class of bioengineered long-acting factors approved for the treatment and prevention of bleeding episodes in haemophilia B. The aim of this work was to describe the manufacturing process for rFIXFc, to assess product quality and to evaluate the capacity of the process to remove impurities and viruses. This manufacturing process utilized a transferable and scalable platform approach established for therapeutic antibody manufacturing and adapted for production of the rFIXFc molecule. rFIXFc was produced using a process free of human- and animal-derived raw materials and a host cell line derived from human embryonic kidney (HEK) 293H cells. The process employed multi-step purification and viral clearance processing, including use of a protein A affinity capture chromatography step, which binds to the Fc portion of the rFIXFc molecule with high affinity and specificity, and a 15 nm pore size virus removal nanofilter. Process validation studies were performed to evaluate identity, purity, activity and safety. The manufacturing process produced rFIXFc with consistent product quality and high purity. Impurity clearance validation studies demonstrated robust and reproducible removal of process-related impurities and adventitious viruses. The rFIXFc manufacturing process produces a highly pure product, free of non-human glycan structures. Validation studies demonstrate that this product is produced with consistent quality and purity. In addition, the scalability and transferability of this process are key attributes to ensure consistent and continuous supply of rFIXFc.

    Introduction Long-acting reversible contraceptives (LARCs) reduce rates of unintended pregnancies and repeat abortion. Uptake and continuation rates of LARCs are very low in Nepal, despite free provision from most health facilities. We sought to establish the effectiveness of a new approach to LARC promotion in Nepal. Methods We examined change in contraceptive method mix in Nepal using service data resulting from introduction of a balanced counseling (BC) approach to family planning (FP). All staff located at nine randomly selected FP sites were trained and began applying BC in April and May 2014. Women who accepted LARCs from a participating facility were re-contacted at 1, 3, 6 and 12 months. We estimated the LARC continuation rate and assessed determinants of continuation using descriptive analysis, Kaplan-Meier survival curves and univariate and multivariate Cox proportional hazard analysis. Results A total of 5744 women received BC between April and July 2014. 1580 women (27.5 %) took up LARCs, raising its contribution to contraceptive method mix at [organization] to 40 %, significantly higher than the 15 % recorded in 2013. 913 women were followed-up, and the LARC continuation rate at 12 months was 82 %. Women's reported satisfaction with LARC [AHR 0.23; 95 % CI 0.14-0.39, p = 0.000] was the single strongest determinant of LARC continuation after adjusting for all background characteristics. Discussion The findings suggest BC is an effective approach for increasing LARC uptake in Nepal. The rate of LARC continuation and its determinants are important inputs to strategies for improved delivery of FP services.

    Both contraceptive use and fertility rates are high fertility in Malawi. Status of women remains low and is believed to affect reproductive health decisions including use of Long Acting and Permanent Contraceptives Method (LAPCM). This study seeks to examine the relationship between women empowerment and LAPCM. A measure of women's empowerment is derived from the women's responses to questions on the number of household decisions in which the respondent participates, employment status, type of earnings, women's control over cash earnings and level of education. The study is based on a sub sample of 5,948 married women from the 2010 Malawi Demographic and Health Survey. Data was analysed using descriptive statistics, Chi-square and multinomial logistic regression models (α=5%). The prevalence of current use of LAPCM was 20.0% and increases with increasing empowerment level (pempowerment score of women who are currently using LAPCM were 38.53±6.2 years and 6.80±2.9 respectively. Urban women (22.2%) were more currently using LAPCM than rural women (19.4%) pWomen who belong to Seven Day Adventists/Baptist were 1.51(C.I=1.058-2.153; p=0.023) more likely and Muslims were 0.58(C.I=0.410-0.809; p=0.001) less likely to currently use LAPCM than Catholic women. Being in the richest wealth quintile (OR=1.91; C.I=1.362-2.665; pwomen who have access to FP programmes on media and increases consistently with increasing women empowerment level even when other potential confounding variables were used as control. In Malawi, LAPCM is still underutilized and more than half of the women are not adequately empowered. Women empowerment, wealth quintile and access to FP programmes are key factors influencing the use of LAPCM. Programmes that address these determinants are urgently needed in Malawi.

    Full Text Available Abstract Background Because wide variations in mental health care utilization exist throughout the world, determining long-term effectiveness of psychotropic medications in a real-world setting would be beneficial to physicians and patients. The purpose of this analysis was to describe the effectiveness of injectable risperidone long-acting therapy (RLAT for schizophrenia across countries. Methods This was a pragmatic analysis of data from two prospective observational studies conducted in the US (Schizophrenia Outcomes Utilization Relapse and Clinical Evaluation [SOURCE]; ClinicalTrials.gov registration number for the SOURCE study: NCT00246194 and Spain, Australia, and Belgium (electronic Schizophrenia Treatment Adherence Registry [eSTAR]. Two separate analyses were performed to assess clinical improvement during the study and estimate psychiatric hospitalization rates before and after RLAT initiation. Clinical improvement was evaluated using the Clinical Global Impressions-Severity (CGI-S and Global Assessment of Functioning (GAF scales, and change from baseline was evaluated using paired t tests. Psychiatric hospitalization rates were analyzed using incidence densities, and the bootstrap resampling method was used to examine differences between the pre-baseline and post-baseline periods. Results The initial sample comprised 3,069 patients (US, n = 532; Spain, n = 1,345; Australia, n = 784; and Belgium, n = 408. In all, 24 months of study participation, completed by 39.3% (n = 209, 62.7% (n = 843, 45.8% (n = 359, and 64.2% (n = 262 of patients from the US, Spain, Australia, and Belgium, respectively, were included in the clinical analysis.

    Bronchodilators are central to the symptomatic management of patients with COPD.Previous data have shown that inhaled indacaterol improved numerous clinical outcomes over placebo. This systematic review explored the efficacy and safety of indacaterol in comparison with tiotropium or bid long-acting β 2 -agonists (TD-LABAs) for treatment of moderate to severe COPD. Randomized controlled trials were identified after a search of different databases of published and unpublished trials. Five trials (5,920 participants) were included. Compared with tiotropium, indacaterol showed statistically and clinically significant reductions in the use of rescue medication and dyspnea(43% greater likelihood of achieving a minimal clinically important difference [MCID] in the transitional dyspnea index [TDI]; number needed to treat for benefit [NNTB] 5 10). Additionally,the MCID in health status was more likely to be achieved with indacaterol than with tiotropium (OR = 1.43; 95% CI, 1.22–1.68; P = .00001; [NNTB ]= 10). Trough FEV 1 was significantly higher at the end of treatment with indacaterol than with TD-LABAs (80 mL, P = .00001). Similarly, indacaterol signifi cantly improved dyspnea (61% greater likelihood of achieving an MCID in TDI, P = .008) and health status (21% greater likelihood of achieving an MCID in St. George’s Respiratory Questionnaire, P 5 .04) than TD-LABA. Indacaterol showed similar levels of safety and tolerability to both comparators. Available evidence suggests that indacaterol may prove useful as an alternative to tiotropium or TD-LABA due to its effects on health status, dyspnea, and pulmonary function.

    Purpose Providing long-acting reversible contraception (LARC) in the immediate postpartum period is an evidence-based strategy for expanding women's access to highly effective contraception and for reducing unintended and rapid repeat pregnancy. The purpose of this article is to demonstrate the application of implementation science methodology to study the complexities of rolling-out policies that promote immediate postpartum LARC use across states. Description The Immediate Postpartum LARC Learning Community, sponsored by the Association of State and Territorial Health Officials (ASTHO), is made up of multi-disciplinary, multi-agency teams from 13 early-adopting states with Medicaid reimbursement policies promoting immediate postpartum LARC. Partners include federal agencies and maternal and child health organizations. The Learning Community discussed barriers, opportunities, strategies, and promising practices at an in-person meeting. Implementation science theory and methods, including the Consolidated Framework for Implementation Research (CFIR), and a recent compilation of implementation strategies, provide useful tools for studying the complexities of implementing immediate postpartum LARC policies in birthing facilities across early adopting states. Assessment To demonstrate the utility of this framework for guiding the expansion of immediate postpartum LARC policies, illustrative examples of barriers and strategies discussed during the in-person ASTHO Learning Community meeting are organized by the five CFIR domains-intervention characteristics, outer setting, inner setting, characteristics of the individuals involved, and process. Conclusion States considering adopting policies can learn from ASTHO's Immediate Postpartum LARC Learning Community. Applying implementation science principles may lead to more effective statewide scale-up of immediate postpartum LARC and other evidence-based strategies to improve women and children's health.

    The new rDNA and DNA-derived "basal" insulin analogs, glargine and detemir, represent significant advancement in the treatment of diabetes compared with conventional NPH insulin. This review describes blood glucose homeostasis by insulin in people without diabetes and outlines the physiological application of exogenous insulin in patients with type 1 and type 2 diabetes. The requirements for optimal basal insulin treatment are discussed and the methods used in the evaluation of basal insulins are presented. An essential criterion in the development of an "ideal" basal insulin preparation is that the molecular modifications made to the human insulin molecule do not compromise safety. It is also necessary to obtain a clear understanding of the pharmacokinetic and pharmacodynamic characteristics of the two currently available basal insulin analogs. When comparing glargine and detemir, the different molar concentration ratios of the two insulin formulations should be considered along with the nonspecificity of assay systems used to determine insulin concentrations. However, euglycemic clamp studies in crossover study design provide a good basis for comparing the pharmacodynamic responses. When the latter is analyzed by results of intervention clinical trials, it is concluded that both glargine and detemir are superior to NPH in type 1 and type 2 diabetes. However, there is sufficient evidence to demonstrate that these two long-acting insulin analogs are different in both their pharmacokinetic and pharmacodynamic profiles. These differences should be taken into consideration when the individual analogs are introduced to provide basal insulin supplementation to optimize blood glucose control in patients with type 1 and type 2 diabetes as well. PubMed-Medline was searched for articles relating to pharmacokinetics and pharmacodynamics of glargine and detemir. Articles retrieved were reviewed and selected for inclusion if (1) the euglycemic clamp method was used with a

    TransCon growth hormone is a sustained-release human growth hormone prodrug under development in which unmodified growth hormone is transiently linked to a carrier molecule. It is intended as an alternative to daily growth hormone in the treatment of growth hormone deficiency. This was a multi-center, randomized, open-label, active-controlled trial designed to compare the safety (including tolerability and immunogenicity), pharmacokinetics and pharmacodynamics of three doses of weekly TransCon GH to daily growth hormone (Omnitrope). Thirty-seven adult males and females diagnosed with adult growth hormone deficiency and stable on growth hormone replacement therapy for at least 3 months were, following a wash-out period, randomized (regardless of their pre-study dose) to one of three TransCon GH doses (0.02, 0.04 and 0.08 mg GH/kg/week) or Omnitrope 0.04 mg GH/kg/week (divided into 7 equal daily doses) for 4 weeks. Main outcomes evaluated were adverse events, immunogenicity and growth hormone and insulin-like growth factor 1 levels. TransCon GH was well tolerated; fatigue and headache were the most frequent drug-related adverse events and reported in all groups. No lipoatrophy or nodule formation was reported. No anti-growth hormone-binding antibodies were detected. TransCon GH demonstrated a linear, dose-dependent increase in growth hormone exposure without accumulation. Growth hormone maximum serum concentration and insulin-like growth factor 1 exposure were similar after TransCon GH or Omnitrope administered at comparable doses. The results suggest that long-acting TransCon GH has a profile similar to daily growth hormone but with a more convenient dosing regimen. These findings support further TransCon GH development.

    Full Text Available Abstract Background This observational study was designed to collect treatment outcomes data in patients using the electronic Schizophrenia Treatment Adherence Registry (e-STAR. Methods Patients with schizophrenia or schizoaffective disorder in Australia who were prescribed risperidone long-acting injection (RLAI between 2003 and 2007 were assessed 12-months retrospectively, at baseline and 24-months prospectively at 3-monthly intervals. The intent-to-treat population, defined as all patients who received at least one dose of RLAI at baseline, was used for the efficacy and safety analyses. Results At total of 784 patients (74% with schizophrenia, 69.8% male with a mean age of 37.1 ± 12.5 years and 10.6 ± 9.5 years since diagnosis were included in this Australian cohort. A significant improvement in mean Clinical Global Impression - severity score was observed at 24-months (4.52 ± 1.04 at baseline, 3.56 ± 1.10 at 24-months. Most of this improvement was seen by 3-months and was also reflected in mean Global Assessment of Functioning score, which improved significantly at 24-months (42.9 ± 14.5 at baseline, 59 ± 15.4 at 24-months. For patients still receiving RLAI at 24-months there was an increase from a mean baseline RLAI dose of 26.4 ± 5 mg to 43.4 ± 15.7 mg. Sixty-six percent of patients discontinued RLAI before the 24-month period--this decreased to 46% once patients lost to follow-up were excluded. Conclusion Over the 24-month period, initiation of RLAI was associated with improved patient functioning and illness severity in patients with schizophrenia or schizoaffective disorder. Improved outcomes were observed early and sustained throughout the study. Trial Registration Clinical Trials Registration Number, NCT00283517.

    Full Text Available Abstract Background Inhibition of vascular smooth muscle cell (vSMC proliferation by oral anti-hyperglycemic agents may have a role to play in the amelioration of vascular disease in diabetes. Thiazolidinediones (TZDs inhibit vSMC proliferation but it has been reported that they anomalously stimulate [3H]-thymidine incorporation. We investigated three TZDs, two biguanides and two sulfonylureas for their ability of inhibit vSMC proliferation. People with diabetes obviously have fluctuating blood glucose levels thus we determined the effect of media glucose concentration on the inhibitory activity of TZDs in a vSMC preparation that grew considerably more rapidly under high glucose conditions. We further explored the mechanisms by which TZDs increase [3H]-thymidine incorporation. Methods VSMC proliferation was investigated by [3H]-thymidine incorporation into DNA and cell counting. Activation and inhibition of thymidine kinase utilized short term [3H]-thymidine uptake. Cell cycle events were analyzed by FACS. Results VSMC cells grown for 3 days in DMEM with 5% fetal calf serum under low (5 mM glucose and high (25 mM glucose increased in number by 2.5 and 4.7 fold, respectively. Rosiglitazone and pioglitazone showed modest but statistically significantly greater inhibitory activity under high versus low glucose conditions (P 3H]-thymidine into DNA but did not increase cell numbers. Troglitazone inhibited serum mediated thymidine kinase induction in a concentration dependent manner. FACS analysis showed that troglitazone and rosiglitazone but not pioglitazone placed a slightly higher percentage of cells in the S phase of a growing culture. Of the biguanides, metformin had no effect on proliferation assessed as [3H]-thymidine incorporation or cell numbers whereas phenformin was inhibitory in both assays albeit at high concentrations. The sulfonylureas chlorpropamide and gliclazide had no inhibitory effect on vSMC proliferation assessed by either [3H

    The efficacy and safety of oral tolperisone hydrochloride (Mydocalm) in the treatment of painful reflex muscle spasm was assessed in a prospective, randomized, double-blind, placebo-controlled trial. A total of 138 patients, aged between 20 and 75 years, with painful reflex muscle spasm associated with diseases of the spinal column or proximal joints were enrolled in eight rehabilitation centers. Patients were randomized to receive either 300 mg tolperisone hydrochloride or placebo for a period of 21 days. Both treatment groups recovered during the 3 weeks rehabilitation program. However, tolperisone hydrochloride proved to be significantly superior to placebo: the change score of the pressure pain threshold as the primary target parameter significantly increased during therapy with tolperisone hydrochloride (P = 0.03, valid-case-analysis) compared to the results obtained on placebo treatment. The overall assessment of efficacy by the patient also demonstrated significant differences in favor of tolperisone hydrochloride. Best results were seen in patients aged between 40 and 60 years with a history of complaints shorter than 1 year and with concomitant physical therapy. The evaluation of safety data, i.e., adverse events, biochemical and hematological laboratory parameters, demonstrated no differences between tolperisone hydrochloride and placebo. As a conclusion tolperisone hydrochloride represents an effective and safe treatment of painful reflex muscle spasm without the typical side effects of centrally active muscle relaxants.

  15. Long-acting methylphenidate formulations in the treatment of attention-deficit/hyperactivity disorder: a systematic review of head-to-head studies

    2013-01-01

    Background The stimulant methylphenidate (MPH) has been a mainstay of treatment for attention-deficit/hyperactivity disorder (ADHD) for many years. Owing to the short half-life and the issues associated with multiple daily dosing of immediate-release MPH formulations, a new generation of long-acting MPH formulations has emerged. Direct head-to-head studies of these long-acting MPH formulations are important to facilitate an evaluation of their comparative pharmacokinetics and efficacy; however, to date, relatively few head-to-head studies have been performed. The objective of this systematic review was to compare the evidence available from head-to-head studies of long-acting MPH formulations and provide information that can guide treatment selection. Methods A systematic literature search was conducted in MEDLINE and PsycINFO in March 2012 using the MeSH terms: attention deficit disorder with hyperactivity/drug therapy; methylphenidate/therapeutic use and All Fields: Concerta; Ritalin LA; OROS and ADHD; Medikinet; Equasym XL and ADHD; long-acting methylphenidate; Diffucaps and ADHD; SODAS and methylphenidate. No filters were applied and no language, publication date or publication status limitations were imposed. Articles were selected if the title indicated a comparison of two or more long-acting MPH preparations in human subjects of any age; non-systematic review articles and unpublished data were not included. Results Of 15,295 references returned in the literature search and screened by title, 34 articles were identified for inclusion: nine articles from pharmacokinetic studies (nine studies); nine articles from laboratory school studies (six studies); two articles from randomized controlled trials (two studies); three articles from switching studies (two studies) and three articles from one observational study. Conclusions Emerging head-to-head studies provide important data on the comparative efficacy of the formulations available. At a group level, efficacy

Materials and methods: Five studies are presented: one single ascending dose study in healthy Caucasian males; two multiple ascending dose studies in healthy males, one in Caucasians and one in Japanese; a Phase IIA asthma study; and a Phase IIB COPD study. Subjects received AZD3199 via a Spira nebulizer (Turbuhaler; equivalent delivered doses 5–3200 µg or Turbuhaler (single delivered doses of 120–1920 µg or repeated delivered once-daily doses 240–1,680 µg. AZD3199 pharmacokinetics were assessed using total plasma concentration and urinary excretion, and tolerability using adverse events, clinical laboratory tests, and physical examinations. Results: AZD3199 appeared rapidly in the systemic circulation following single and multiple dosing in healthy volunteers and patients (maximum plasma concentration within 30 minutes, with dose-proportional time-independent pharmacokinetics. Plasma exposure to unmetabolized drug was similar in healthy volunteers and patients with asthma, but relatively lower in patients with COPD. Estimated terminal half-life was up to 142 hours in healthy Caucasian males. AZD3199 was well tolerated and showed no or at most mild systemic effects. Conclusion: AZD3199 plasma exposure in healthy volunteers and patients suggested linear pharmacokinetics and a long half-life. Systemic availability was similar in healthy subjects and patients with asthma, but was lower in patients

    OBJECTIVE To examine current levels, current correlates of, and changes in long-acting reversible contraceptive (LARC) use, including intrauterine devices and implants, among females aged 15–44 years using contraception between 2008–2010 and 2011–2013 with specific attention to associations between race, income, and age and their LARC use. METHODS We analyzed data from two rounds of the National Survey of Family Growth, nationally representative samples of females aged 15–44 years, consisting of 6,428 females in 2008–2010 and 5,601 females in 2011–2013. We conducted simple and multivariable logistic regression analyses with adjustments for the sampling design to identify demographic characteristics predictive of LARC use and changes in these patterns between the two time periods. In this cross-sectional, descriptive study, our primary outcome of interest was current prevalence of LARC use among all contraceptive users at the time of the interview. RESULTS The prevalence of LARC use among contracepting U.S. females increased from 8.5% in 2009 to 11.6% in 2012 (P<.01). The most significant increases occurred among Hispanic females (from 8.5% to 15.1%), those with private insurance (7.1–11.1%), those with fewer than two sexual partners in the previous year (9.2–12.4%), and those who were nulliparous (2.1–5.9%) (all P<.01). In multivariable analyses adjusting for key demographic characteristics, the strongest associations with LARC use in 2012 were parity (adjusted odds ratios [ORs] 4.3–5.5) and having a history of stopping non-LARC hormonal use (adjusted OR 1.9). Women aged 35–44 years (adjusted OR 0.3) were less likely to be LARC users than their counterparts (all P<.001). Poverty status was not associated with LARC use. There were no differences in discontinuation of LARC methods resulting from dissatisfaction between minority women and non-Hispanic white women. CONCLUSION During the most recent time period surveyed, use of LARC methods

    The efficacy of ivermectin long-acting injection (IVM LAI, IVOMEC® GOLD, Merial; 3.15 % ivermectin w/v) formulation was evaluated in cattle with induced Sarcoptes scabiei var. bovis or Psoroptes ovis infestations. A total of 64 cattle were included in this series of four studies, with 16 animals per study. Approximately, 8 weeks following initial induced mite infestation, cattle were allocated to treatment groups based on decreasing pre-treatment bodyweights. Treatments (saline (control) or IVM LAI (630 mcg ivermectin/kg bodyweight) at 1 mL/50 kg bodyweight) were administered by a single subcutaneous injection in front of the right shoulder on Day 0. Skin scrapings were collected prior to treatment and at approximately weekly intervals for 8 weeks thereafter to establish live mite counts. Character and extent of skin lesions were evaluated at each sampling. Animals were weighed before treatment and at the end of the studies. Mite counts of the IVM LAI-treated animals were significantly (p studies at all occasions post-treatment. In the two Sarcoptes studies, IVM LAI-treated cattle were free of mites at 14 days after treatment and in the Psoroptes studies at 13 or 28 days post-treatment. All IVM LAI-treated cattle remained free of mites to the end of the studies while all control animals remained infested. Mange lesions of the IVM LAI-treated animals improved significantly (p studies) and from Days 28 or 34 (Psoroptes studies). In all studies, mean weight gain over the 8 week post-treatment period was significantly (p studies, 64.1 and 68.6 kg vs. 46.9 and 48.6 kg, respectively; Psoroptes studies, 43.0 and 43.4 kg vs. 20.8 and 34.9 kg, respectively. All animals accepted the treatment well, and no treatment-related health problems and adverse events were observed throughout the studies. These studies demonstrated the high efficacy of IVOMEC® GOLD against sarcoptic and psoroptic mange in cattle.

    BACKGROUND AND PURPOSE: Impulse control disorders (ICDs) in Parkinson's disease (PD) are associated primarily with dopamine agonist (DA) use. Comparative surveys of clinical occurrence of impulse control behaviours on longer acting/transdermal DA therapy across age ranges are lacking. The aim...... on medical records and clinical interviews of patients initiating or initiated on DA treatment (both short- and long-acting, and transdermal) across a broad range of disease stages and age groups was performed. RESULTS: Four hundred and twenty-five cases were included [mean age 68.3 years (range 37-90), mean...... release PPX (PPX-IR) (19.0%; P therapy due to ICDs were low. CONCLUSION: Our data suggest a relatively low rate of ICDs with long-acting or transdermal DAs, however these preliminary observational data need to be confirmed with prospective studies controlling...

    The use of long acting contraceptive methods (LACMs) is one of the strategies for preventing mother-to-child transmission (MTCT) of HIV. Studies noted that significant proportion of unintended pregnancy among HIV positive women was due to contraceptive failure mainly of short term contraceptives. This highlights the need to use most effective types of modern contraception, long acting contraceptive. However, studies conducted on demand for long acting contraceptive methods in this particular group of people are scarce in Ethiopia. This study aimed to assess demand for long acting contraceptive methods and associated factors among married reproductive age women attending care at Antiretroviral treatment (ART) clinics in public health institutions at Bahir Dar City, Northwest Ethiopia. Institution-based cross-sectional study was conducted among 654 systematically selected women attending care in ART clinics in public health facilities at Bahir Dar city from March to April, 2014. A structured and pretested interviewer administered questionnaire was used to collect data. Data were entered using EPI info version 3.5.3 and then exported to SPSS version 16 for analysis. Descriptive statistics were used to describe the socio-demographic and economic characteristics of the study participants. Logistic regression analyses were employed to identify factors associated with demand for long acting contraceptive methods. Odds ratios with 95 % CI were used to assess the presence and strength of association. A total of 654 respondents have participated in the study (response rate 99. 09 %). The demand for long acting contraceptive methods was 36.7 % (95 % CI: 33.2 %, 40.6 %). The odds of demand for LACMs among HIV positive women who were living in urban were three times [AOR = 3.05, 95 % CI: 1.34, 6.89] higher than those who were living in rural. The odds of demand for LACMs among the respondents who were in elementary educational level were two times [AOR = 2.31, 95

    Full Text Available Charlotte Suppli UlrikDepartment of Pulmonary Medicine, Hvidovre Hospital and University of Copenhagen, Copenhagen, DenmarkBackground: Long-acting bronchodilators are central in the pharmacological management of patients with chronic obstructive pulmonary disease (COPD. The aim of this systematic review is to provide an overview of the studies evaluating the safety and clinical efficacy of inhaled glycopyrronium bromide, a novel long-acting muscarinic antagonist, in patients with COPD.Methods: This study was performed as a systematic literature review.Results: Inhaled glycopyrronium bromide seems to be a safe and well tolerated long-acting muscarinic antagonist with a fast onset of action. In patients suffering from moderate to severe COPD, glycopyrronium bromide has clinically important effects on level of forced expiratory volume in one second, use of relief medication, percentage of days with no use of rescue medication, daytime dyspnea scores, and probably also on health status. Furthermore, in this group of patients, glycopyrronium bromide has beneficial effects on dynamic hyperinflation and exercise tolerance. Glycopyrronium bromide has been shown to reduce the rate of exacerbations in patients with moderate to severe COPD, but long-term controlled trials with exacerbation rate as the primary outcome variable have not been published yet.Conclusion: Once-daily inhaled glycopyrronium bromide has characteristics important for use in COPD, including a fast onset of action, sustained 24-hour bronchodilatation, and improvement in exercise tolerance, and therefore appears to have the potential for a significant role in the future management of COPD.Keywords: chronic obstructive pulmonary disease, glycopyrronium bromide, long-acting bronchodilators

    Octreotide may extend survival in hepatocellular carcinoma (HCC). Forty-one per cent of HCCs have high-affinity somatostatin receptors. We aimed to determine the feasibility, safety, and activity of long-acting octreotide in advanced HCC; to identify the best method for assessing somatostatin receptor expression; to relate receptor expression to clinical outcomes; and to evaluate toxicity. Sixty-three patients with advanced HCC received intramuscular long-acting octreotide 20 mg monthly until progression or toxicity. Median age was 67 years (range 28-81 years), male 81%, Child-Pugh A 83%, and B 17%. The aetiologies of chronic liver disease were alcohol (22%), viral hepatitis (44%), and haemochromatosis (6%). Prior treatments for HCC included surgery (8%), chemotherapy (2%), local ablation (11%), and chemoembolisation (6%). One patient had an objective partial tumour response (2%, 95% CI 0-9%). Serum alpha-fetoprotein levels decreased more than 50% in four (6%). Median survival was 8 months. Thirty four of 61 patients (56%) had receptor expression detected by scintigraphy; no clear relationship with clinical outcomes was identified. There were few grade 3 or 4 toxicities: hyperglycaemia (8%), hypoglycaemia (2%), diarrhoea (5%), and anorexia (2%). Patients reported improvements in some symptoms, but no major changes in quality of life were detected. Long-acting octreotide is safe in advanced HCC. We found little evidence of anticancer activity. A definitive randomised trial would identify whether patients benefit from this treatment in other ways.

    Full Text Available Gregory D Salinas, Caroline O Robinson, Maziar AbdolrasulniaCE Outcomes LLC, Birmingham, AL, USAAbstract: With increasing numbers of patients experiencing chronic pain, opioid therapy is becoming more common, leading to increases in concern about issues of abuse, diversion, and misuse. Further, the US Food and Drug Administration recently released a statement notifying sponsors and manufacturers of extended-release and long-acting opioids of the need to develop Risk Evaluation and Mitigation Strategies (REMS programs in order to ensure that the benefits of this therapy choice outweigh the potential risks. There is little research on physician opinions concerning opioid-prescribing and education policies. To assess attitudes surrounding new opioid policies, a survey was designed and distributed to primary care physicians in October 2011. Data collected from 201 primary care physicians show that most are not familiar with the REMS requirements proposed by the Food and Drug Administration for extended-release and long-acting opioids; there is no consensus among primary care physicians on the impact of prescribing requirements on patient education and care; and increasing requirements for extended-release and long-acting opioid education may decrease opioid prescribing. Physician attitudes toward increased regulatory oversight of opioid therapy prescriptions should be taken into consideration by groups developing these interventions to ensure that they do not cause undue burden on already busy primary care physicians.Keywords: REMS, opioids, attitudes, survey

    Full Text Available BACKGROUND: The aim of this study was to evaluate the impact of Quality and Outcomes Framework (QOF, a major pay-for-performance programme in the United Kingdom, on prescribing of long-acting reversible contraceptives (LARC in primary care. METHODS: Negative binomial interrupted time series analysis using practice level prescribing data from April 2007 to March 2012. The main outcome measure was the prescribing rate of long-acting reversible contraceptives (LARC, including hormonal and non hormonal intrauterine devices and systems (IUDs and IUSs, injectable contraceptives and hormonal implants. RESULTS: Prescribing rates of Long-Acting Reversible Contraception (LARC were stable before the introduction of contraceptive targets to the QOF and increased afterwards by 4% annually (rate ratios  = 1.04, 95% CI = 1.03, 1.06. The increase in LARC prescribing was mainly driven by increases in injectables (increased by 6% annually, which was the most commonly prescribed LARC method. Of other types of LARC, the QOF indicator was associated with a step increase of 20% in implant prescribing (RR =  1.20, 95% CI =  1.09, 1.32. This change is equivalent to an additional 110 thousand women being prescribed with LARC had QOF points not been introduced. CONCLUSIONS: Pay for performance incentives for contraceptive counselling in primary care with women seeking contraceptive advice has increased uptake of LARC methods.

    To study differences in clinical outcomes between initiating glucagon-like peptide-1 receptor agonist (GLP-1 RAs) vs insulin treatment in patients with type 2 diabetes treated with oral glucose-lowering medications (OGLM). Prospective, randomized trials comparing GLP-1 RA and insulin treatment head-to-head as add-on to OGLM were identified (PubMed). Differences from baseline values were compared for HbA1c, fasting plasma glucose, bodyweight, blood pressure, heartrate and lipoproteins. Proportions of patients reporting hypoglycaemic episodes were compared. Of 712 publications identified, 23 describing 19 clinical trials were included in the meta-analysis. Compared to insulin, GLP-1 RAs reduced HbA1c more effectively (Δ -.12%, P heartrate was higher with GLP-1 RAs ( P < .0001). Triglycerides and LDL cholesterol were significantly lower with GLP-1 RAs. Long-acting GLP-1 RAs were better than short-acting GLP-1 RAs in reducing HbA1c and fasting glucose, but were similar regarding bodyweight. Slightly better glycaemic control can be achieved by adding GLP-1 RAs to OGLM as compared to insulin treatment, with added benefits regarding bodyweight, hypoglycaemia, blood pressure and lipoproteins. These differences are in contrast to the fact that insulin is prescribed far more often than GLP-1 RAs. © 2016 John Wiley & Sons Ltd.

    Antagonists of 5HT3 receptors are clinically effective in treating nausea and emesis associated with certain oncolytic drugs, including cisplatin. Moreover, these agents may be useful in pharmacological management of several central nervous system disorders, including anxiety, schizophrenia, dementia, and substance abuse. Our studies on aroyltropanamides led to the discovery that dihydrobenzofuranyl esters and amides are potent 5HT3 receptor antagonists. Simple benzoyl derivatives of tropine and 3 alpha-aminotropane possessed weak 5HT3 receptor antagonist activity, as judged by blockade of bradycardia produced by iv injection of serotonin (5HT) to anesthetized rats. Within this series, use of benzofuran-7-carboxamide as the aroyl moiety led to a substantial increase of 5HT3 receptor affinity. The optimal 5HT3 receptor antagonist identified via extensive SAR studies was endo-5-chloro-2,3-dihydro-2,2-dimethyl-N-(8-methyl-8-azabicyclo[3.2.1]oc t- 3-yl)-7-benzofurancarboxamide (Z)-2-butenedioate (zatosetron maleate). The 7-carbamyl regiochemistry, dimethyl substitution, chloro substituent, and endo stereochemistry were all crucial elements of the SAR. Zatosetron maleate was a potent antagonist of 5HT-induced bradycardia in rats (ED50 = 0.86 micrograms/kg i.v.). Low oral doses of zatosetron (30 micrograms/kg) produced long-lasting antagonism of 5HT3 receptors, as evidenced by blockade of 5HT-induced bradycardia for longer than 6 h in rats. Moreover, this compound did not produce hemodynamic effects after i.v. administration to rats, nor did it block carbamylcholine-induced bradycardia in doses that markedly blocked 5HT3 receptors. Thus, zatosetron is a potent, selective, orally effective 5HT3 receptor antagonist with a long duration of action in rats.

    Full Text Available Objectives: Long-acting bronchodilators are mainstay treatment for moderate to severe chronic obstructive pulmonary disease. A growing body of evidence indicates an increased risk of cardiovascular events upon initiation of these medications. We hypothesize that this risk is higher in patients with chronic obstructive pulmonary disease who had a preexisting cardiovascular disease regardless of receipt of any cardiovascular medication. Methods: A retrospective cohort of patients with a diagnosis of chronic obstructive pulmonary disease based on two outpatient visits or one inpatient visit for chronic obstructive pulmonary disease (International Classification of Diseases, 9th Edition, Clinical Modification codes 491.x, 492.x, 496 in any year between 2001 and 2012 from a commercial insurance database. We then selected those initiating long-acting bronchodilator treatments between April 2001 and September 2012. Each patient had a 1 year look back period to determine history of cardiovascular disease or cardiovascular disease treatment from the time of first prescription of long-acting beta agonist, long-acting muscarinic antagonist, or long-acting beta agonist combined with inhaled corticosteroids. Patients were followed for 90 days for hospitalizations or emergency department visits for cardiovascular event. The cohort was divided into four groups based on the presence of cardiovascular disease (including ischemic heart disease, hypertension, ischemic stroke, heart failure, tachyarrhythmias and artery disease based on International Classification of Diseases, 9th Edition, Clinical Modification codes and cardiovascular disease treatment defined as acetylsalicylic acid, beta blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, antiplatelet, anticoagulants, calcium channel blockers, nitrate, digoxin, diuretics, antiarrhythmics or statins.

    To model the cost effectiveness of paliperidone palmitate (paliperidone long-acting injectable; PLAI), a new once-monthly long-acting antipsychotic therapy, compared with risperidone long-acting injectable (RLAI) and olanzapine pamoate (OLAI), in multi-episode patients (two or more relapses) with schizophrenia in Sweden. A Markov decision analytic model was developed to simulate the history of a cohort of multi-episode patients transitioning through different health states on a monthly basis over a 5-year time horizon from the perspective of the Swedish healthcare system. Therapeutic strategies consisted of starting treatment with RLAI (mean dose 37.5 mg every 2 weeks), PLAI (mean dose 75 mg equivalent (eq.) every month) or OLAI (150 mg every 2 weeks or 300 mg every 4 weeks). Probability of relapse, level of adherence, side-effects (extrapyramidal symptoms, tardive dyskinesia, weight gain and diabetes) and treatment discontinuation (switch) were derived from long-term observational data when feasible. Incremental cost-effectiveness outcomes, discounted at 3% annually, included cost per quality-adjusted life-year (QALY) and cost per relapse avoided (expressed in 2009 Swedish Krona SEK). Relative to RLAI and OLAI, PLAI is economically dominant: more effective (additional QALYs, less relapses) and less costly treatment option over a 5-year time horizon. The results were robust when tested in sensitivity analysis. The impact of once-monthly treatment on adherence levels is not yet known, and not all variables that could impact on real-world outcomes and costs were included in this model. PLAI was cost saving from a Swedish payer perspective compared with RLAI and OLAI in the long-term treatment of multi-episode (two or more relapses) schizophrenia patients.

NNTs for prevention of relapse ranged from 2 to 5 for paliperidone palmitate, haloperidol decanoate, and fluphenazine decanoate, indicating a moderate to large effect size.Results: Among the selected maintenance studies, NNH varied considerably, but indicated a lower likelihood of encountering extrapyramidal side effects, such as akathisia, tremor, and tardive dyskinesia, with paliperidone palmitate versus placebo than with first-generation antipsychotic depot agents versus placebo. This was further supported by an overall higher NNH for paliperidone palmitate versus placebo with respect to anticholinergic use and Abnormal Involuntary Movement Scale positive score. LHH for preventing relapse versus use of anticholinergics was 15 for paliperidone palmitate and 3 for fluphenazine decanoate, favoring paliperidone palmitate.Conclusion: Overall, paliperidone palmitate had a similar NNT and a more favorable NNH compared with the first-generation long-acting injectables assessed.Keywords: long-acting injectables, first-generation antipsychotics

    BACKGROUND: About two thirds of adults suffer from backpain at some time during their life. In the emergency room many patients with acute back pain are treated with intravenous non-steroidal analgesics. Whether this treatment is superior to oral administration of non-steroidal analgesics is unknown. Intravenous administration, however, requires considerable amounts of resources and accounts for high workload in busy clinics. In the further course centrally acting muscle relaxants are prescribed but the effectiveness remains unclear. The objective of this study is on the one hand to compare the effectiveness of intravenous with oral non-steroidal analgesics for acute treatment and on the other hand to compare the effectiveness of a centrally active muscle relaxant with placebo given for three days after presentation to the ED (emergency department). METHODS/DESIGN: This study is intended as a randomised controlled factorial trial mainly for two reasons: (1) the sequence of treatments resembles the actual proceedings in every-day clinical practice, which is important for the generalisability of the results and (2) this design allows to take interactions between the two sequential treatment strategies into account. There is a patient preference arm included because patients preference is an important issue providing valuable information: (1) it allows to assess the interaction between desired treatment and outcome, (2) results can be extrapolated to a wider group while (3) conserving the advantages of a fully randomised controlled trial. CONCLUSION: We hope to shed more light on the effectiveness of treatment modalities available for acute low back pain.

    The aim of the study was to obtain a comparative evaluation of antihypertensive efficacy, tolerability and influence of combine therapy on myocardium mass, diastolic function of a left ventricle, lipid and carbohydrate exchange in patients with arterial hypertension in metabolic syndrome. Out of 40 examined cases 20 patients took enalapril and long-acting nifedipin and 20 ones--enalapril and moxonidine. All examination were been performed before administration of drugs and 6 months after the therapy. The dynamics of indices of ambulatory blood pressure monitoring, echocardiography, cycle ergometry, anthropometry, lipid, carbohydrate exchange and tolerability of conducted therapy was been evaluated. The use of this combination of the drugs may be recommended to be included in the treatment of arterial hypertension within the bounds of metabolic syndrome, as in most of cases they promote an achievement of target blood pressure level, have a cardioprotective action, high tolerability and favorable metabolic profile. The combination of enalapril and long-acting nifedipin has a more evident antihypertensive activity but a therapy with enalapril and moxonidine has a positive effect on the indices of carbohydrate exchange.

    Pituitary apoplexy is characterized by abrupt onset of haemorrhage or non-haemorrhagic infarction of a pituitary adenoma. The clinical features include acute onset severe headache, visual field defects, meningeal irritation, ophthalmoplegia and hypopituitarism. The pituitary apoplexy may be clinically silent in ∼25% of patients. We report a case of acromegaly due to pituitary macroadenoma. The patient was started on long-acting octreotide therapy. On 3-month follow-up, the patient showed clinical and biochemical remission and the magnetic resonance imaging (MRI) of the brain showed subclinical haemorrhage and resolution of tumour. The octreotide therapy was stopped. On 6-month follow-up, the patient was still in remission and the MRI of brain revealed non-enhancing mixed intensities haemorrhagic and cystic areas of the pituitary gland. In our patient, whether spontaneous remission of acromegaly due to subclinical pituitary haemorrhage was coincidental or due to long-acting octreotide therapy is still a dilemma. We report this case because of rarity and clinical importance of this unusual occurrence. PMID:27123308

    Users' sensory perceptions and experiences of intravaginal products can inform acceptability and adherence. Focusing on the meanings women derive from formulation/device characteristics facilitates developers' design iterations toward optimizing user experience. We investigated how users of long-acting gels and intravaginal rings (IVRs) impute meaning to characteristics that may affect future product use. Focus groups were conducted with contraceptive IVR and vaginal lubricant users. Current perceptibility science and historical theory on the cultural acceptability of fertility regulating methods informed the analysis. A total of 21 IVR users and 29 lubricant users attended focus groups in which they manipulated products in their hands and discussed reactions to product characteristics. Participants used prior product experiences and sensory perceptions of prototype manipulations to inform meanings about product properties and performance for pregnancy, disease prevention, comfort, and perceived efficacy. The meanings derived from product characteristics depended on why the product would be used; a characteristic deemed problematic in one risk context may be considered preferable in another. Intravaginal product users create narratives that ascribe influence or causality to product characteristics. These meanings, whether correct or incorrect biologically, will shape vaginal product acceptability, use, and effectiveness. Long-acting and sustained-release drug delivery systems will be part of the multipurpose prevention continuum. Developers must consider how sensory experiences and culturally salient assumptions shape the meanings users make of product design characteristics. Those meanings will ultimately impact use and effectiveness. Copyright © 2015 Elsevier Inc. All rights reserved.

    1991-10-01

    Two groups, each composed of 20 women, who used depomedroxyprogesterone acetate (DMPA) or norethisterone enanthate (NET-EN) injectable contraceptives were investigated for changes in 75-g OGTT and in the fasting and two-hour post oral glucose load (2-hours) levels of serum insulin, growth hormone, glucagon, cortisol and blood pyruvate. Samples were taken before and 3, 6 and 12 months after use of injectables. DMPA and NET-EN caused significant changes in mean blood glucose and pyruvate and in mean serum insulin, growth hormone and glucagon, but not in mean fasting cortisol. Changes with NET-EN started after 3 months, became maximal after 6 months and reverted to normal after 12 months of use, due to more frequent administration during the first 6 months of use (every 60 +/- 5 days) and to more spacing of the injections (every 84 +/- 5 days) after that. Changes with DMPA started after 3 months, and increased with the duration of use to become maximal after 12 months. Maximal changes were similar with DMPA and NET-EN and consisted of: a significant increase in fasting blood glucose and pyruvate and serum insulin; a significant increase in 2-hour blood glucose and pyruvate, serum insulin, growth hormone and glucagon. Although significant changes in blood glucose levels occurred with both DMPA and NET-EN, yet they did not reach the lower cut-off levels for impaired glucose tolerance in any user. With the same spacing of injections, i.e. every 84 +/- 5 days for NET-EN and every 90 +/- 5 days for DMPA, the effects on various parameters studied were less with NET-EN.

    Full Text Available Abstract Background Contraceptive use including short acting, long acting and permanent methods positively influence the socio-economic development of a nation by allowing families to space and limit their family size to their economic capacity. Demand for LAPMs of contraception as detrmined by utilization and unmet need for LAPMs of contraception can provide realiable information for providers. Objective To determine the utilization of long acting and permanent contraception and its associated factors among married women of Goba town, South East Ethiopia. Methods A cross sectional community based study was conducted among 734 systematically selected married women of reproductive age in Goba town in September/ 2009. A structured and pretested, interview questionaire was used to collect data on socio-demographic, behavioral factors and data related to demand for LAPMs of contraception. Data were analyzed using EPI INFO and SPSS version 16. Result The demand for Long Acting and Permanent Methods (LAPMs of contraception was 18.1%. Utilization of LAPMs of contraception in the town was 64 (8.7% and the unmet need for LAPMs was 69 (9.4%. Information on LAPMs in the town was 636 (86.6%. Media (radio and television was the major sources of information 641 (87.3%. The use of LAPMs was significatly associated with ever use AOR[17.43, 95% CI:9.19, 33.03], number of times discussions made on methods AOR[4.6, 95% CI: 1.72,12.17] and main decider of using methods AOR[ 2.2, 95% CI:1.03, 4.65].

    Full Text Available INTRODUCTION: Observational studies using case-control designs have showed an increased risk of pneumonia associated with inhaled corticosteroid (ICS-containing medications in patients with chronic obstructive pulmonary disease (COPD. New-user observational cohort designs may minimize biases associated with previous case-control designs. OBJECTIVE: To estimate the association between ICS and pneumonia among new users of ICS relative to inhaled long-acting bronchodilator (LABD monotherapy. METHODS: Pneumonia events in COPD patients ≥45 years old were compared among new users of ICS medications (n = 11,555; ICS, ICS/long-acting β2-agonist [LABA] combination and inhaled LABD monotherapies (n = 6,492; LABA, long-acting muscarinic antagonists using Cox proportional hazards models, with propensity scores to adjust for confounding. SETTING: United Kingdom electronic medical records with linked hospitalization and mortality data (2002-2010. New users were censored at earliest of: pneumonia event, death, changing/discontinuing treatment, or end of follow-up. OUTCOMES: severe pneumonia (primary and any pneumonia (secondary. RESULTS: Following adjustment, new use of ICS-containing medications was associated with an increased risk of pneumonia hospitalization (n = 322 events; HR = 1.55, 95% CI: 1.14, 2.10 and any pneumonia (n = 702 events; HR = 1.49, 95% CI: 1.22, 1.83. Crude incidence rates of any pneumonia were 48.7 and 30.9 per 1000 person years among the ICS-containing and LABD cohorts, respectively. Excess risk of pneumonia with ICS was reduced when requiring ≥1 month or ≥ 6 months of new use. There was an apparent dose-related effect, with greater risk at higher daily doses of ICS. There was evidence of channeling bias, with more severe patients prescribed ICS, for which the analysis may not have completely adjusted. CONCLUSIONS: The results of this new-user cohort study are consistent with published findings; ICS were

    Hierarchical porous fibre scaffolds with mesoporous bioglasses (MBGs) and polylactic acid (PLA) were successfully fabricated by the electrospinning method. These compound scaffolds possess macropores with sizes of about 100 nm because of the solvent evaporation from the fibre and the mesoporous structure ( ∼4.0 nm) originated from MBGs. The biomineralisation ability was investigated in simulated body fluid. The fibre structure is beneficial for inducing the growth of hydroxyapatite. In addition, compared with pure MBGs, the materials (MP-1 and MP-2) exhibit a long-acting drug release process up to 140 h and the drug release process corresponds with the Fickian diffusion mechanism. With the special fibre morphology and the hierarchical porous structure, the MBGs/PLA fibre scaffolds are expected to have potential application for bone tissue repair and regeneration.

    A multicenter, open-label, phase 2 study was conducted to investigate the efficacy and safety of long-acting pasireotide formulation in Japanese patients with acromegaly or pituitary gigantism. Medically naïve or inadequately controlled patients (on somatostatin analogues or dopamine agonists) were included. Primary end point was the proportion of all patients who achieved biochemical control (mean growth hormone [GH] levelsacromegaly, n=32; pituitary gigantism, n=1) were enrolled and randomized 1:1:1 to receive open-label pasireotide 20mg, 40mg, or 60mg. The median age was 52 years (range, 31-79) and 20 patients were males. At month 3, 18.2% of patients (6/33; 90% confidence interval: 8.2%, 32.8%) had biochemical control (21.2% [7/33] when including a patient with mean GHacromegaly or pituitary gigantism.

    Clinical management of persistent adrenocorticotropin hormone (ACTH) excess in Nelson syndrome (NS) and Cushing disease (CD) remains a challenge. Somatostatin and its analogs as octreotide decrease ACTH secretion through somatostatin receptors of pituitary cells. To our knowledge, there are no reports on the effect of long-acting repeatable octreotide (oct-lar) on hormonal secretion and quality of life in patients with NS and CD who failed conventional therapy. Herein, we describe the effects of treatment with oct-lar (20 mg/month intramurally) in 1 woman with NS and 2 women with persistent CD. Oct-lar therapy reduced ACTH secretion and improved the quality of life in NS patient. By contrast, in CD patients, it failed to control ACTH and cortisol secretion, and the quality of life remained unchanged.

    Degludec is the most recent molecule of the ultra-long-acting basal insulin analogues approved for human use. It forms soluble multihexamers which after subcutaneous injection are converted into monomers, and are thus slowly and continuously absorbed into the bloodstream. This absorption mechanism confers degludec an ultra-long and stable action profile, with no concentration peaks. This paper discusses the most recent studies in patients with type 1 and 2 diabetes mellitus, which showed degludec to be non inferior in decreasing HbA1c, ensuring optimum glycemic control similar to that achieved with insulin glargine or detemir. Degludec also had an improved safety profile, as it was associated to a significantly lower rate of nocturnal hypoglycemia in both types of diabetes and to a potentially lower overall hypoglycemia rate in type 2 DM. Degludec also opens the possibility to use more flexible regimens.

    Indacaterol is a novel, inhaled, ultra-long-acting β(2)-agonist providing 24-h bronchodilation with once-daily (od) dosing for maintenance use in patients with chronic obstructive pulmonary disease (COPD). This article reviews the bronchodilator properties of indacaterol compared with other treatments used in COPD. Data from five published placebo-controlled studies were reviewed. Two 14-day crossover studies, the first comparing indacaterol 300 µg od with salmeterol 50 µg twice daily (bid), the second comparing indacaterol 150 µg and 300 µg od with tiotropium 18 µg od, assessed forced expiratory volume in 1 s (FEV(1)) at 24 h postdose (trough). Third, a 14-day crossover study evaluated trough FEV(1) following indacaterol 300 µg dosed morning or evening compared with salmeterol 50 µg bid. Fourth, a single-dose study of indacaterol 150 and 300 µg measured FEV(1) at 5 min postdose compared with salmeterol/fluticasone 50/500 µg and salbutamol 200 µg. Finally, data from a 1-year study with indacaterol 300 µg and formoterol 12 µg bid were examined to determine whether bronchodilation was maintained long term. In the first two studies, indacaterol increased trough FEV(1) after 14 days by a statistically significant and clinically relevant margin over placebo; indacaterol had a greater effect than salmeterol and a similar effect to tiotropium. In the third study, indacaterol had the same effect on trough FEV(1) whether dosed in the morning or evening. In the fourth study, the onset of the bronchodilator effect of indacaterol was similar to that of salbutamol. In the fifth study, the bronchodilator effect of indacaterol on trough FEV(1) was maintained at a significant and clinically relevant level over 52 weeks, whereas the bronchodilator effect of formoterol diminished over time. To conclude, indacaterol is a highly effective bronchodilator that is superior to or at least as effective as other available long-acting bronchodilators for COPD.

    The aim of this study was to determine whether suppression of the seasonal increase in prolactin concentrations by chronic treatment with the dopamine agonist bromocriptine would affect onset of anoestrus, voluntary food intake, body weight, and wool growth in a seasonal breed of sheep. Groups of eight Scottish Blackface ewes were injected i.m. each week with either the vehicle (Group A) or 2.0 mg (Group B), 6.0 mg (Group C), or 18.0 mg (Group D) of bromocriptine in a long-acting formulation, commencing on 18 January and terminating on 25 July (midwinter to midsummer in the northern hemisphere). Immediately before the bromocriptine injection, blood samples were taken for progesterone and prolactin determination. Voluntary food intakes were measured daily, and body weights were recorded every fortnight. Estimates of wool growth were made by weighing wool clipped from a measured area of skin once a month. Treatment had no effect on onset of anoestrus, voluntary food intake, body weight, or wool growth. Plasma prolactin concentrations increased significantly in all groups during the treatment period. From January to April, all doses of bromocriptine significantly reduced prolactin concentrations but later in the study (May and June) prolactin was significantly suppressed in Group D only, although even in this group prolactin concentrations increased between March and June. Pituitary prolactin content, measured at the end of the study in July, was also suppressed by bromocriptine. The gradual increase in prolactin concentrations in ewes receiving chronic bromocriptine was further investigated by treating a fifth group of ewes (Group E) with 18.0 mg of long-acting bromocriptine each week, commencing on 20 June.(ABSTRACT TRUNCATED AT 250 WORDS)

    Murthy, G.; Hargens, A. R.; Lehman, S.; Rempel, D.

    1999-01-01

    Muscle fatigue is a common musculoskeletal disorder in the work place, and may be a harbinger for more disabling cumulative trauma disorders. Although the cause of fatigue is multifactorial, reduced blood flow and muscle oxygenation may be the primary factor in causing muscle fatigue during low intensity muscle exertion. Muscle fatigue is defined as a reduction in muscle force production, and also occurs among astronauts who are subjected to postural constraints while performing lengthy, repetitive tasks. The objectives of this research are to: 1) develop an objective tool to study the role of decreased muscle oxygenation on muscle force production, and 2) to evaluate muscle fatigue during prolonged glovebox work.

    Sexual dysfunction, particularly erectile dysfunction (ED), is common in men with type 2 diabetes, occurring in up to 75% of cases. The prevalence of hypogonadism is also high in men with diabetes and low testosterone is associated with both sexual dysfunction and a reduced response to oral therapy for ED. This study aimed to determine the effect of testosterone replacement with long-acting Testosterone Undecanoate (TU) on sexual function, mood and quality of life vs. placebo over a treatment period of 30 weeks followed by 52 weeks of open-label medication. The study was conducted in a primary care population of men with type 2 diabetes attending their primary care physician for routine visits. The male diabetic populations of seven general practices were screened at routine diabetes visits to detect symptomatic men with total testosterone levels of 12 nmol/L or less or with free testosterones of 250 pmol/L or less. Two hundred eleven men were screened. A double-blind placebo-controlled study was conducted in 199 men with type 2 diabetes and hypogonadism treated for 30 weeks with either 1,000 mg of TU or matching placebo followed by 52-week open-label follow on. The primary outcome measure, International Index of Erectile Function (IIEF), was used to evaluate sexual dysfunction, and the Ageing Male Symptom (AMS), Hospital Anxiety and Depression Scale, and Global Efficacy Question were used as secondary outcome measures to assess mood and self-reported quality of life. Testosterone replacement therapy with long-acting TU improved all domains of sexual function at 30 weeks (erectile function [EF], P = 0.005; intercourse satisfaction, P = 0.015; sexual desire, P = 0.001; overall satisfaction, P = 0.05; and orgasm, P = 0.04), with benefit as early as 6 weeks. Improvements in AMS score were significant in men without depression (P = 0.02) and the presence of depression at baseline was associated with marked reduction in response to both sexual function and psychological

    Full Text Available OBJECTIVE: The aim of this study was to assess the existence of myofunctional alterations before and after first premolar extraction in Class II/1 malocclusion patients that could endanger the long-term dental arch stability. MATERIAL AND METHODS: The study was performed by means of morphological, functional and electromyographic analyses in 17 Class II/1 malocclusion patients (group T and 17 Class I malocclusion patients (group C, both groups with 12-30-year age range (mean age: 20.93 ± 4.94 years. RESULTS: Data analyzed statistically by Student's t-test showed a significant decrease in the maxillary and mandibular dental arch perimeters after orthodontic treatment (p0.05. However, group T differed significantly from group C (p<0.05. The electromyographic data showed that the anterior right and left suprahyoid muscles acted synergistically in both groups, while having a lower myoelectric activity in group T during swallowing. CONCLUSIONS: Myofunctional alterations observed after the orthodontic treatment in Class II/1 malocclusion seemed to jeopardize the long-term orthodontic stability, making recurrence possible. Further research should be conducted to compare electromyographic data before and after orthodontic treatment in order to corroborate the results of the present investigation.

    Chronic neuropsychiatric disorders and diabetes mellitus affect millions of patients and require long-term supervision and expensive medical care. Although repeated drug administration can help manage these diseases, relapses and re-hospitalization owing to patient non-adherence and reduced therapeutic efficacy remain challenging. In response, long-acting injectables, which provide sustained drug release over longer periods at concentrations close to therapeutic ranges, have been proposed. Recent advancements include polymeric long-acting injectables (pLAIs), in which the active pharmaceutical ingredient (API) is encapsulated within U.S. Food and Drug Administration (FDA)-approved biocompatible polymers, such as poly(lactic-co-glycolic acid), or PLGA. Despite significant progress and development in the global pLAI market, FDA guidance for the approval of complex drug products, such as generic pLAIs, is not clearly defined. Although in vitro to in vivo correlation (IVIVC) can facilitate the identification of critical quality attributes (CQAs), drug formulations, and in vitro test platforms for evaluating drug performance in vivo, the application of IVIVC in order to shortlist time- and resource-intensive clinical trials for generic pLAIs has not been reported. Here, we propose a new Level A Type IVIVC that directly correlates the in vitro outcomes, such as drug dissolution, of candidate generic formulations with the clinical characteristics, such as drug absorption, of a reference listed drug (RLD), to help identify the specific generic pLAI formulations with clinical absorptions that are likely to be similar to that of the RLD, thereby reducing the number of clinical trials required for evaluation of clinical bioequivalence (BE). Therefore, the scope of the proposed method is intended only for the rational design of clinical trials, i.e., to shortlist the specific pLAI generic formulations for clinical BE evaluation, and not necessarily to analyze drug performances

    Full Text Available Abstract Background The long acting β2-agonists, salmeterol and formoterol, have been recommended, by some, as first line treatment of stable chronic obstructive pulmonary disease (COPD. We reviewed evidence of efficacy and safety when compared with placebo or anticholinergic agents in patients with poorly reversible COPD. Methods After searching MEDLINE, EMBASE, HealthSTAR, BIOSIS Previews, PASCAL, ToxFile, SciSearch, the Cochrane Library, and PubMed, as well as Web sites, selected journals, reference lists, and contacting drug manufacturers, two reviewers independently screened reports of randomised controlled trials of parallel or crossover design lasting four weeks or longer and including patients with a forced expiratory volume in one second (FEV1 ≤ 75% of predicted, a ratio of FEV1 to forced vital capacity (FVC ≤ 88% of predicted, and Results Twelve trials satisfied our inclusion criteria; eight were high quality (Jadad score >2 and four were low quality (≤ 2. The adequacy of allocation concealment was unclear in all of them. We did not perform a meta-analysis due to differences in trial design and how outcomes were reported. Two trials comparing salmeterol with ipratropium did not detect differences; one trial comparing formoterol and ipratropium described greater improvement with formoterol in morning PEFR (15.3 versus 7.1 l/min, p = 0.040. Of twelve trials comparing long acting β2 agonists with placebo, six reported no improvement in exercise capacity, eleven reported improvements in FEV1 lung function (one reported no improvement, six reported less rescue inhaler usage (one reported no difference and five reported improved dyspnea scores (two reported no improvement. Differences in quality of life were detected in one salmeterol trial ; however, two salmeterol, and one formoterol trial reported no differences. Adverse effects of interest were not reported. Conclusion In terms of clinical outcomes and safety, we could not find

    Cydectin(®) 2% LA Solution for Injection for Sheep (Pfizer Animal Health) is a long-acting (LA) formulation of moxidectin for the treatment and prevention of mixed infections of gastro-intestinal nematodes, respiratory nematodes and certain arthropod parasites in sheep. To evaluate the duration of persistent efficacy against nasal bots (Oestrus ovis), a natural exposure study was conducted in Spain during the summer of 2011. One hundred and twenty nasal bot-free, Rasa Aragonesa sheep were randomly allocated to eight groups of 15 animals each. On Day 0, four groups were treated at the recommended dose rate of 1 mg moxidectin/kg bodyweight. Four groups remained untreated as negative controls. All animals were held in nasal bot-proof housing except for exposure to natural challenge when one group of treated sheep and one of group of control animals were transferred to a local pasture at either 0-20, 20-40, 40-60, or 60-80 days after treatment. Following challenge, sheep were scored for clinical signs of bot infestation, necropsied and the heads sectioned for larval recovery. Nasal bot larvae were retrieved from 7 to 11 control sheep following each exposure period indicating that adult bots were active throughout the study. In the first challenge up to 20 days after treatment, when sheep were slaughtered immediately after exposure, the majority of larvae were first instar (L1) and only 3 of the 15 control sheep were infested with second instars (L2). There was 100% efficacy against L2 and 38.1% reduction in the number of live L1 in the treated sheep but mean counts were not significantly different between treatment and control groups (P ≥ 0.05). For the subsequent exposure periods 20-80 days after treatment (necropsies 7-9 days after challenge), 6-10 sheep were infested with L1 and 9-11 control sheep were infested with L2 and third instars (L3). There was negligible efficacy against L1, but treatment with moxidectin resulted in 100% control of L2 and L3. These

    Prototypical long-acting kappa opioid receptor (KOPR) antagonists [e.g., norbinaltorphimine (norBNI)] have been reported to exert anxiolytic-like effects in several commonly used anxiety tests in rodents including the novelty-induced hypophagia (NIH) and elevated plus maze (EPM) tests. It remains unknown if the short-acting KOPR antagonists (e.g., zyklophin and LY2444296) have similar effects. In this study effects of zyklophin and LY2444296 (s.c.) were investigated in the NIH and EPM tests in mice 1h post-injection and compared with norBNI (i.p.) 48h post-administration. In the NIH test, zyklophin at 3 and 1mg/kg, but not 0.3mg/kg, or LY2444296 at 30mg/kg decreased the latency of palatable food consumption in novel cages, but had no effect in training cages, similar to norBNI (10mg/kg). Zyklophin at 3 or 1mg/kg increased or had a trend of increasing the amount of palatable food consumption in novel cages, with no effects in training cages, further indicating its anxiolytic-like effect, but norBNI (10mg/kg) and LY2444296 (30mg/kg) did not. In the EPM test, norBNI (10mg/kg) increased open arm time and % open arm entries or time, but zyklophin at all three doses and LY2444296 (30mg/kg) had no effects. In addition, zyklophin at 3mg/kg increased numbers of close and total arm entries on EPM, suggesting increased activity; however, norBNI and LY2444296 had no effects on close and total arm entries. Thus, all three KOPR antagonists had anxiolytic-like effects in the NIH test. However, only the long-acting one (norBNI), but not the short-acting ones (zyklophin and LY2444296), demonstrated anti-anxiety like effects in the EPM test. It remains to be investigated if the differences are due to the differences in their durations of action and/or pharmacodynamic properties.

    Pasireotide long-acting release is a somatostatin analog that is indicated for treatment of patients with acromegaly. This analysis documents the safety of pasireotide long-acting release in patients with acromegaly enrolled in the ACCESS trial (ClinicalTrials.gov identifier: NCT01995734). ACCESS is an open-label, multicenter, single-arm, expanded-treatment protocol designed to provide patients access to pasireotide long-acting release pending regulatory approval. Patients received pasireotide long-acting release 40 mg administered intramuscularly every 28 days. The primary outcome was the proportion of patients having a treatment-emergent grade ≥3 or serious adverse event. Efficacy data were not collected. Forty-four adult patients with active acromegaly were enrolled in the study for an average of 37.6 weeks (range, 4-70 weeks). Twenty-five grade ≥3 treatment-emergent adverse events were reported in 11 patients (25.0 %), 3 of whom (27.3 %) experienced grade ≥3 hyperglycemia. In patients treated with pasireotide long-acting release for ≥3 months (n = 42), mean glycated hemoglobin and fasting plasma glucose levels increased significantly from 5.9 % and 100.4 mg/dL at baseline to 6.8 % and 135.9 mg/dL at 3 months, respectively. Ten patients (22.7 %) were treated with pasireotide long-acting release for ≥15 months, after which mean glycated hemoglobin and fasting plasma glucose levels were 6.3 % and 123 mg/dL, respectively. Twenty-one patients (48 %) initiated antidiabetic medication. Grade ≥3 adverse events (primary outcome) were reported in 25.0 % of acromegaly patients treated with pasireotide long-acting release in a clinical setting. Hyperglycemia-related adverse events were reported in 45.5 % of patients, but were typically manageable, supporting the role of pasireotide long-acting release as a safe treatment option for acromegaly patients.

    Both sodium-glucose co-transporter-2 inhibitors (SGLT-2Is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) have been consistently found to lower blood glucose, body weight and systolic blood pressure (SBP) in patients with type 2 diabetes mellitus (T2DM). While all the SGLT-2Is inhibit glucose reabsorption by blocking SGLT-2 receptor in kidney, dose-dependently, the highest licensed dose of canagliflozin 300-mg has an additional ability to inhibit SGLT-1 receptor in intestine transiently, that may lead to additional inhibition of prandial glucose absorption, unlike other approved highly selective SGLT-2Is. Areas covered: An electronic search on studies with highest licensed dose of all approved SGLT-2Is and long-acting GLP-1RAs was made up to December 2016. We systemically reviewed the studies of canagliflozin 300-mg and compared its glucose, body weight and SBP lowering with other approved SGLT-2Is and GLP-1RAs in their highest approved doses. Expert commentary: From the available evidences, it appears that canagliflozin 300-mg may have the highest potential to improve gluco-metabolic profile in T2DM, amongst the SGLT-2Is class. While the highest approved dosage of GLP-1RAs lowered HbA1c better than canagliflozin 300-mg, weight and SBP lowering could be non-inferior or slightly better with the latter drug. Nonetheless, only head-to-head trial can conclusively answer these questions.

    The ethical issues experienced by mental health nurses in administering antipsychotic depot and long-acting intramuscular injections (LAI) were explored in the present study. Mental health nurses face ethically-difficult situations when administering these medications. A phenomenological research method guided by Max van Manen's human science approach describes and interprets the ethical issues involved in performing the procedure. Purposive and snowball sampling was used to select eight participants from two mental health hospitals. Semistructured interviews were carried out to collect data. A thematic analysis was conducted on the data. The four main themes that emerged from the analyses were: (i) lack of alternatives; (ii) safety; (iii) feeling uncomfortable; and (iv) difficulty maintaining the therapeutic relationship. The findings suggest that mental health nurses face ethical challenges in administering LAI. The findings raise much needed awareness of the need for mental health nurses and nurse educators to consider the ethical issues experienced while performing the procedure. There is a need for nurse education providers and organizations to provide opportunities for mental health nurses to address their 'lived experiences'. Educational courses are needed to equip mental health nurses with the technical and critical thinking skills to administer safe and effective antipsychotic depot and LAI.

    The objective of the study was to determine the stress levels of girls with central precocious puberty (CPP) before and during treatment with a long-acting gonadotropin-releasing hormone agonist (GnRHa). The Child Stress Scale (CSS) was used for 10 unrelated girls with CPP before and after the first year of GnRHa treatment. The CSS is divided into four subscales (physical, psychological, psychological with depressive component and psychophysiological reactions). Through a quantitative analysis, it is possible to classify stress into four stages: alarm, resistance, near-exhaustion and exhaustion. At diagnosis, 90% of the girls showed stress levels scores at the alarm or resistance stage on at least one subscale, mostly in terms of physical and psychological reactions. The mean total stress score was significantly higher before when compared to after GnRHa treatment (43.4±15.6 vs. 28.9±9.7; pstress scores obtained in all subscales, except the one on psychophysiological reactions, were significantly higher before GnRHa treatment. Higher stress levels were a common finding in girls with CPP before treatment. The significant stress level reduction after pubertal suppression reinforces the idea that sexual precocity is a stressful condition in children. The CSS might be a useful tool for psychological assessment of patients with CPP.

    As programs continue to expand access to family planning information, services, and products, it is critical that these efforts be undertaken with an equity lens, ensuring that regardless of socioeconomic status, all women and couples can use the method that meets their needs. This study explores the relationship between household wealth and the use of long-acting and permanent methods (LAPMs) versus short-acting methods of contraception among modern method users, using multivariate analyses based on Demographic Health Survey data from 30 developing countries conducted between 2006 and 2013. Overall, and controlling for relevant individual and household characteristics including age, number of living children, education, and urban/rural residence, we found that wealthier women were more likely than poorer women to use LAPMs instead of short-acting methods: 20 of the 30 countries showed a positive and statistically significant association between wealth and LAPM use. For 10 of those countries, however, LAPM use was significantly higher only for the top (1 or 2) wealthiest quintiles. Eight countries showed no broad pattern of association, while in 2 countries-Bangladesh and India-poorer women were more likely to use LAPMs than wealthier women. The positive association between wealth and LAPM use was found most consistently in the Latin American and the Caribbean countries in our sample. These findings can help program implementers respond better to women's needs for modern contraception, especially in reaching women from lower- and middle-income households.

    Background Risperidone long-acting injection (RLAI) has been shown to be efficacious, improve compliance, and increase long-term retention rate on therapy. The aim of this work was to determine the effect of RLAI on clinical outcome and hospitalization rate in patients with schizophrenia or schizoaffective disorder enrolled in the electronic Schizophrenia Treatment Adherence Registry in Latin America. Methods Data were collected at baseline, retrospectively for the 12 months prior to baseline, and prospectively every three months for 24 months. Hospitalization prior to therapy was assessed by a retrospective chart review. Efficacy and functioning were evaluated using Clinical Global Impression of Illness Severity (CGI-S), Personal and Social Performance (PSP), and Global Assessment of Functioning (GAF) scores. Relapse and treatment were also registered. Results Patients were recruited in Mexico (n = 53), Brazil (n = 11), and Colombia (n = 15). Sixty-five percent (n = 52) were male, and mean age was 32.9 years. Patients were classified as having schizophrenia (n = 73) or schizoaffective disorder (n = 6). The mean dose of RLAI at six months was 34.1 mg (standard deviation = 10.2 mg). The percentage of hospitalized patients before treatment was 28.2% and 5.1% at six months after initiating RLAI (P < 0.001). Significant changes were registered on CGI-S, GAF, and PSP scores. Conclusions RLAI was associated with an improvement in clinical symptoms and functioning, and a greater reduction in hospitalization. PMID:21326651

    Full Text Available Abstract Background This study was undertaken to estimate utility values for alternative treatment intervals for long acting antipsychotic intramuscular injections for the treatment of schizophrenia. Methods Vignettes were developed using the published literature and an iterative consultation process with expert clinicians and patient representative groups. Four vignettes were developed. The first was a vignette of relapsed/untreated schizophrenia. The other three vignettes presented a standardised picture of well-managed schizophrenia with variations in the intervals between injections: once every 2-weeks, 4-weeks and 3-months. A standardised time trade off (TTO approach was used to obtain utility values for the vignettes. As a societal perspective was sought, a representative sample of individuals from across the community (Sydney, Australia was recruited. Ninety-eight people completed the TTO interview. The vignettes were presented in random order to prevent possible ordering effects. Results A clear pattern of increasing utility was observed with increasing time between injections. Untreated schizophrenia was rated as very poor health-related quality of life with a mean (median utility of 0.27 (0.20. The treated health states were rated at much higher utilities and were statistically significantly different (p Conclusions This study has provided robust data indicating that approximately a 0.05 utility difference exists between treatment options, with the highest utility assigned to 3-monthly injections.

    Full Text Available A 46-year-old woman with acromegaly and hyperthyroidism due to a pituitary adenoma. She had high serum thyroid-stimulating hormone (TSH levels and very high serum growth hormone (GH levels. Transsphenoidal removal of the tumor, post-operative irradiation, frontal craniotomy for removal of residual tumor and large-dose bromocriptine therapy were carried out consecutively. After therapy, serum GH levels gradually decreased, but not to the normal range, and serum TSH levels remained at inappropriately normal levels. Using immunoperoxidase techniques, GH-, TSH- and follicle-stimulating hormone (FSH-containing cells were demonstrated in the adenoma. A long-acting somatostatin analogue (SMS 201-995, 600 micrograms/day suppressed the serum GH level to the normal range with a concomitant suppression of TSH. Furthermore, the paradoxical serum GH responses to TRH and LH-RH were slightly improved. No important subjective side-effects were noted. Therefore, SMS 201-995 appeared to be a very effective drug in this patient with a GH- and TSH-producing pituitary tumor.

Despite differences in the pharmacological properties between two well-established ICS/LABA products (budesonide/formoterol and fluticasone/salmeterol), data from randomized clinical trials (RCTs) and meta-analyses suggest that these two products perform similarly under RCT conditions. In contrast, a few recently reported real-world comparative effectiveness studies have suggested that there are substantial differences between ICS/LABA combination treatments in terms of clinical and healthcare outcomes in patients with asthma or COPD. The purpose of this article is to provide a brief review of the benefits, as well as the limitations, of comparative effectiveness research (CER) in the therapeutic area of asthma and COPD. We conducted a structured literature review of the current CER studies on ICS/LABA combinations in asthma and COPD. These articles were then used to illustrate the unique challenges of CER studies, providing a summary of study results and limitations. We focus particularly on difficult biases and confounding factors that may be introduced before, during, and after the initiation of therapy. Beyond being a review of these two ICS/LABA combination treatments, this article is intended to help those who wish to assess the quality of CER published projects in asthma and COPD, or guide investigators who wish to design new CER studies for chronic respiratory disease treatments.

    An unintended consequence of extended-release (ER) and long-acting (LA) prescription opioids is that these formulations can be more attractive to abusers than immediate-release (IR) formulations. The US Food and Drug Administration recognized these risks and approved the ER/LA Opioid Analgesic Risk Evaluation and Mitigation Strategy (ER/LA REMS), which has a goal of reducing opioid misuse and abuse and their associated consequences. The primary objective of this analysis is to determine whether ER/LA REMS implementation was associated with decreased reports of misuse and abuse. Data from the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS(R)) System Poison Center Program were utilized. Poison center cases are assigned a reason for exposure, a medical outcome, and a level of health care received. Rates adjusted for population and drug utilization were analyzed over time. RADARS System Poison Center Program data indicate a notable decrease in ER/LA opioid rates of intentional abuse and misuse as well as major medical outcomes or hospitalizations following implementation of the ER/LA REMS. While similar decreases were observed for the IR prescription opioid group, the decreasing rate for the ER/LA opioids exceeded the decreasing rates for the IR prescription opioids and was distinctly different than that for the prescription stimulants, indicating that the ER/LA REMS program may have had an additional effect on decreases in opioid abuse and intentional misuse beyond secular trends.

    Dulaglutide (dula, LY2189265), a long-acting glucagon-like peptide-1 analog, is being developed to treat type 2 diabetes mellitus. To foster the development of dula, we designed a two-stage adaptive, dose-finding, inferentially seamless phase 2/3 study. The Bayesian theoretical framework is used to adaptively randomize patients in stage 1 to 7 dula doses and, at the decision point, to either stop for futility or to select up to 2 dula doses for stage 2. After dose selection, patients continue to be randomized to the selected dula doses or comparator arms. Data from patients assigned the selected doses will be pooled across both stages and analyzed with an analysis of covariance model, using baseline hemoglobin A1c and country as covariates. The operating characteristics of the trial were assessed by extensive simulation studies. Simulations demonstrated that the adaptive design would identify the correct doses 88% of the time, compared to as low as 6% for a fixed-dose design (the latter value based on frequentist decision rules analogous to the Bayesian decision rules for adaptive design). This article discusses the decision rules used to select the dula dose(s); the mathematical details of the adaptive algorithm-including a description of the clinical utility index used to mathematically quantify the desirability of a dose based on safety and efficacy measurements; and a description of the simulation process and results that quantify the operating characteristics of the design. © 2012 Diabetes Technology Society.

    Nationally, the use of long-acting reversible contraception (LARC), specifically intrauterine devices (IUDs) and implants, by teens remains low, despite their effectiveness, safety, and ease of use. To examine patterns in use of LARC among females aged 15-19 years seeking contraceptive services, CDC and the U.S. Department of Health and Human Services' Office of Population Affairs analyzed 2005-2013 data from the Title X National Family Planning Program. Title X serves approximately 1 million teens each year and provides family planning and related preventive health services for low-income persons. Use of LARC among teens seeking contraceptive services at Title X service sites increased from 0.4% in 2005 to 7.1% in 2013 (p-value for trend contraceptive services in 2013, 17,349 (2.8%) used IUDs, and 26,347 (4.3%) used implants. Use of LARC was higher among teens aged 18-19 years (7.6%) versus 15-17 years (6.5%) (pcontraception at Title X service sites have increased use of these methods. Health centers that provide quality contraceptive services can facilitate use of LARC among teens seeking contraception. Strategies to address provider barriers to offering LARC include: 1) educating providers that LARC is safe for teens; 2) training providers on LARC insertion and a client-centered counseling approach that includes discussing the most effective contraceptive methods first; and 3) providing contraception at reduced or no cost to the client.

    Inhaled corticosteroids (ICS) are frequently recommended for the treatment of asthma and COPD, often in combination with long-acting beta2-agonists (LABA), depending on the severity of the disease and/or on the specific phenotype. Several ICS/LABA combinations are currently available that differ in their pharmacokinetic characteristics and dose of both components. Thus, this review assesses differences in the efficacy and the safety profiles of the ICS components in the two more frequently used ICS/LABA combinations (budesonide/formoterol and fluticasone/salmeterol) for the management of COPD. Whereas the basic mechanism of action is similar for all ICS (binding with the intracellular glucocorticoid receptor, which mediates both genomic and non genomic effects), the pharmacokinetic and characteristics of ICS are quite different in terms of receptor affinity, bioavailability, lipophilicity and drug persistence in the airways. Fluticasone persists longer in airway mucus and requires more time to dissolve in the lining fluid and then enter the airway wall, whereas budesonide is cleared more quickly from the airways. Comparative efficacy of the two major ICS/LABA combinations recommended for the treatment of COPD show similar efficacy in terms of reduction of exacerbations, improvement in forced expiratory volume in the first second (FEV1) and quality of life. One retrospective cohort study suggested a greater efficacy for the budesonide/formoterol combination on hospital or emergency department admissions, oral corticosteroid courses, and addition of tiotropium, and an observational real-life study reported a greater reduction of COPD exacerbations with budesonide/formoterol than with fluticasom/salmeterol combination. Among the potential side effects of chronic ICS treatment in patients with COPD, recently the use of fluticasone or fluticasone/salmeterol combination has been associated with a higher prevalence of pneumonia in the major long-term studies.

    Hypothalamic releasing and inhibiting hormones are major neuroendocrine regulators of human body metabolism being driven directly to the anterior pituitary gland via hypothalamic-hypophyseal portal veins. The alternative physiological or therapeutic interventions utilizing the pharmaco-nutritional boost of imidazole-containing dipeptides (non-hydrolized oral form of carnosine, carcinine, N-acetylcarnosine lubricant eye drops) can maintain health, enhance physical exercise performance and prevent ageing. Carnosine (β-alanyl-L-histidine) is synthesized in mammalian skeletal muscle. There is an evidence that the release of carnosine from the skeletal muscle sarcomeres moieties during physical exercise affects autonomic neurotransmission and physiological functions. Carnosine released from skeletal muscle during exercise acts as a powerful afferent physiological signaling stimulus for hypothalamus, may be transported into the hypothalamic tuberomammillary nucleus (TMN), specifically to TMN-histamine neurons and hydrolyzed herewith via activities of carnosine-degrading enzyme (carnosinase 2) localized in situ. Through the colocalized enzymatic activity of Histidine decarboxylase in the histaminergic neurons, the resulting L-histidine may subsequently be converted into histamine, which could be responsible for the effects of carnosine on neurotransmission and physiological function. Carnosine and its imidazole-containing dipeptide derivatives are renowned for their anti-aging, antioxidant, membrane protective, metal ion chelating, buffering, anti-glycation/ transglycating activities used to prevent and treat a spectrum of age-related and metabolic diseases, such as neurodegenerative disease, sight threatening eye diseases, Diabetes mellitus and its complications, cancers and other disorders due to their wide spectrum biological activities.

    Full Text Available Myiasis is a pathologic condition in humans occurring because of parasitic infestation. Parasites causing myiasis belong to the order Diptera. Oral myiasis is seen secondary to oral wounds, suppurative lesions, and extraction wounds, especially in individuals with neurological deficit. In such cases, neglected oral hygiene and halitosis attracts the flies to lay eggs in oral wounds resulting in oral myiasis. We present a case of oral myiasis in 40-year-old male patient with mental disability and history of epilepsy.

    Full Text Available Abstract Background Ethiopia is the second most populous country in Sub-Saharan Africa. Total Fertility Rate of Ethiopia is 5.4 children per women, population growth rate is estimated to be 2.7% per year and contraceptive prevalence rate is only 15% while the unmet need for family planning is 34%. Overall awareness of Family Planning methods is high, at 87%. The prevalence of long acting and permanent contraceptive methods (LAPMs in Tigray region was very low which accounts for 0.1% for implants and no users for intra-uterine contraceptive device (IUCD and female sterilization. Moreover almost all modern contraceptive use in Ethiopia is dependent on short acting contraceptive methods. The objective of this study was to assess factors associated with utilization of long acting and permanent contraceptive methods (LAPM among married women of reproductive age group in Mekelle town. Methods A cross sectional community based survey was conducted from March 9-20, 2011. Multistage sample technique was used to select the participants for the quantitative methods whereas purposive sampling was used for the qualitative part of the study. Binary descriptive statistics and multiple variable regressions were done. Results The study consisted of quantitative and qualitative data. From the quantitative part of the study the response rate of the study was 95.6%. Of the qualitative part two FGDs were conducted for each married women and married men. 64% of the married women heard about LAPMs. More than half (53.6% of the married women had negative attitude towards practicing of LAPMs. The overall prevalence of LAPMs use was 12.3% however; there were no users for female or male sterilization. The main reason cited by the majority of the married women for not using LAPMs was using another method of contraception 360 (93.3%.

    Full Text Available Abstract Background This analysis of pooled data evaluates treatment outcomes of patients with schizophrenia receiving maintenance treatment with olanzapine long-acting injection (OLAI by means of a categorical approach addressing the symptomatic and functional status of patients at different times. Methods Patients were grouped into 5 categories at baseline, 6 months, and 12 months. Shifts between categories were assessed for individual patients and factors associated with improvement were analyzed. 1182 patients from 3 clinical trials were included in the current analysis. Results At baseline, 434 (36.8% patients had minimal Positive and Negative Syndrome Scale (PANSS symptoms but seriously impaired Heinrich Carpenter’s Quality of Life Scale (QLS functioning; 303 (25.6% had moderate to severe symptoms and seriously impaired function; 208 (17.6% had mild to moderate symptoms but good functioning, and 162 (13.7% had minimal symptoms and good functioning. Baseline category was significantly associated with Clinical Global Impression – Severity (CGI-S, extrapyramidal symptoms, working status, age, and number of previous episodes. The majority of all patients starting OLAI treatment maintained or improved (62% at 6 months and 52% at 12 months their symptom and functioning levels on OLAI maintenance treatment. Less than 8% of the patients showed worsening of symptoms or functioning. An improvement in category was associated with high PANSS positive and low CGI-S scores at baseline. Conclusions We present evidence that a composite assessment of schizophrenic patients including symptom severity and functioning is helpful in the evaluation of maintenance treatment outcomes. This approach could also be useful for the assessment of treatment options in clinical practice. The trials from which data are reported here were registered on clinicaltrials.gov as NCT00088491, NCT00088465, and NCT00320489.

    Background Emerging safety issues associated with long-acting beta2-agonist (LABA) have led to multiple regulatory activities by the US Food and Drug Administration (FDA) since 2003, including Drug Safety Communications (DSCs) in 2010. These DSCs had three specific recommendations for the safe use of LABA products in adult asthma treatment. Methods We examined the initiation of LABA-containing products for adult asthma treatment using an intermittent time series approach in a claims database from 2003 to 2012. We assessed the alignment of dispensing patterns with the following 2010 FDA recommendations: 1) contraindicated use of single-ingredient (SI)-LABA without an asthma controller medication (ACM); 2) a LABA should only be used when asthma is not adequately controlled on inhaled corticosteroids (ICSs) or ACM; and 3) step-down asthma therapy (e.g., discontinue LABA) when asthma control is achieved. Results There were 477,922 adults (18–64 years old) dispensed a new LABA during 2003–2012. Among LABA initiators, patients who initiated an SI-LABA and who did “not” have an ACM dispensed on the same date decreased from >9% in 2003 (the initial labeling change) to <2% post 2010 DSCs (p-value <0.0001 in the segmented regression model). The proportion of asthma patients dispensed an ICS in 6 months prior to initiating LABA treatment did not increase. The proportion of patients with longer than 4 months of continuous treatment did not decrease over the study period. Conclusion Although the decrease in SI-LABA initiation is consistent with FDA’s recommendations, low ICS dispensing before initiating a LABA and LABA continuation practices require further efforts to move toward the recommended safe practices.

    The objective of this study was to develop metrics to assess opioid prescribing behavior as part of the evaluation of the Extended-Release/Long-Acting (ER/LA) Opioid Analgesic Risk Evaluation and Mitigation Strategies (REMS). Candidate metrics were selected using published guidelines, examined using sensitivity analyses, and applied to cross-sectional rolling cohorts of Medicare patients prescribed with extended-release oxycodone (ERO) between July 2, 2006 and July 1, 2011. Potential metrics included prescribing opioid-tolerant-only ER/LA opioid analgesics to non-opioid-tolerant patients, prescribing early fills to patients, and ordering drug screens. Proposed definitions for opioid tolerance were seven continuous days of opioid usage of at least 30 mg oxycodone equivalents, within the 7 days (primary) or 30 days (secondary) prior to first opioid-tolerant-only ERO prescription. Forty-four percent of opioid-tolerant-only ERO episodes met the primary opioid tolerance definition; 56% met the secondary definition. Fills were deemed "early" if a prescription was filled before 70% (primary) or 50% (secondary) of the prior prescription's days' supply was to be consumed. Five percent (primary) and 2% (secondary) of episodes had more than or equal to two early fills during treatment. At least one drug screen was billed in 14% of episodes. Stratified analyses indicated that older patients were less likely to be opioid tolerant at the time of the first opioid-tolerant-only ERO prescription. Investigators propose three metrics to monitor changes in prescribing behaviors for opioid analgesics that might be used to evaluate the ER/LA Opioid Analgesics REMS. Low frequencies of patients, particularly those >85 years, were likely to be opioid tolerant prior to receiving prescriptions for opioid-tolerant-only ERO. Wiley Periodicals, Inc.

    Long-acting (LA) preparations of methylphenidate allow for once-daily dosing; however, pharmacokinetics may vary and depend on food intake. The objective was to evaluate effectiveness of a two-phase release formulation (Ritalin(®) LA) under daily practice conditions. This was a prospective, multicenter, observational study in Germany. Eligibility and dosing were determined by the physician based on the drug label. Outcomes included changes over 3 months of treatment in assessments of effect duration, clinical global impression (CGI), and quality of life (ILK). In 101 sites, 262 patients (197 boys, 63 girls, and two unknown) with a mean age of 10.9 years were enrolled; 50 were treated for the first time; 212 switched medication to Ritalin(®) LA. After 3 months, CGI improved in 59.4 % of patients, and well-being overall was rated as good by 61.0 % of parents and 63.7 % of children. Based on parents' assessment, the proportion of children suffering from strong disease burden decreased from 40.7 to 15.1 %. In 123 insufficient responders to previous ADHD medications, benefit from Ritalin(®) LA was above average and effect duration was significantly prolonged as compared to pretreatment. Overall, 28 patients (10.7 %) had treatment-related adverse events with one case being serious; 23 patients (8.8 %) discontinued therapy, 7 (2.7 %) due to poor treatment response; and 212 patients (81 %) continued treatment beyond the study. In line with clinical trial data, Ritalin(®) LA provides significant benefit also under routine practice conditions.

    Body weight loss of Lep(ob/ob) mice in response to leptin is larger than expected from the reduction in energy intake alone, suggesting a thermogenic action of unknown magnitude. We exploited the superior pharmacological properties of a novel long-acting leptin prepared via PASylation to study the contribution of its anorexigenic and thermogenic effects. PASylation, the genetic fusion of leptin with a conformationally disordered polypeptide comprising 600 Pro/Ala/Ser (PAS) residues, provides a superior way to increase the hydrodynamic volume of the fusion protein, thus retarding kidney filtration and extending plasma half-life. Here a single PAS(600)-leptin injection (300 pmol/g) resulted in a maximal weight reduction of 21% 6 days after application. The negative energy balance of 300 kJ/(4 d) was driven by a decrease in energy intake, whereas energy expenditure remained stable. Mice that were food restricted to the same extent showed an energy deficit of only 220 kJ/(4 d) owing to recurring torpor bouts. Therefore, the anorexigenic effect of PAS(600)-leptin contributes 75% to weight loss, whereas the thermogenic action accounts for 25% by preventing hypometabolism. In a second experiment, just four injections of PAS(600)-leptin (100 pmol/g) administered in 5- to 6-day intervals rectified the Lep(ob/ob) phenotype. In total, 16 nmol of PAS(600)-leptin per mouse triggered a weight loss of 43% within 20 days and normalized hypothermia and glucose homeostasis as well as hepatic steatosis. The beneficial properties of PAS(600)-leptin are substantiated by a comparison with previous studies in which approximately 400 nmol (∼25-fold) unmodified leptin was mandatory to achieve similar improvements.

    Indacaterol is a long-acting inhaled beta(2)-agonist (LABA) for the treatment of chronic obstructive pulmonary disease (COPD). In previous studies, indacaterol provided 24 h bronchodilation on once-daily dosing with a fast onset of action. This study compared the efficacy and safety of indacaterol with the twice-daily LABA formoterol and placebo over 1 year. Patients with moderate to severe COPD were randomised to receive once-daily indacaterol 300 microg (n=437) or 600 microg (n=428), twice-daily formoterol 12 microg (n=435) or placebo (n=432) for 52 weeks in a double-blind double-dummy parallel group study. The primary efficacy variable was forced expiratory volume in 1 s (FEV(1)) measured 24 h postdose after 12 weeks (indacaterol vs placebo). Other outcomes included dyspnoea (transition dyspnoea index, TDI), use of as-needed salbutamol, symptom-based measures recorded on diary cards, exacerbations, health status (St George's Respiratory Questionnaire), BODE index (body mass index, obstruction, dyspnoea, exercise), safety and tolerability. Indacaterol increased 24 h postdose FEV(1) after 12 weeks by 170 ml (both doses) versus placebo and by 100 ml versus formoterol (all pindacaterol was more effective than formoterol in improving TDI score and reducing the need for as-needed salbutamol. Indacaterol was well tolerated and had a good overall safety profile, including minimal impact on QTc interval and systemic beta(2)-mediated events. Once-daily indacaterol is an effective 24 h bronchodilator that improves symptoms and health status and confers clinical improvements over a twice-daily 12 h LABA as a treatment for patients with moderate to severe COPD.

    Indacaterol is an inhaled, long-acting β(2)-agonist providing 24-h bronchodilation with once-daily dosing in patients with COPD. Subjects with moderate to severe COPD who completed a 26-week, randomized, double-blind study were eligible for enrollment in an extension, during which treatment with double-blind indacaterol, 150 or 300 μg once daily, or placebo was continued for a further 26 weeks. The primary objective was to evaluate the long-term safety of indacaterol. Efficacy end points included trough (24 h postdose) FEV(1) at 52 weeks, exacerbations, and health status (St. George Respiratory Questionnaire [SGRQ]). Four hundred fifteen subjects participated in the extension. Adverse events, mostly mild or moderate, occurred in 76%, 77%, and 68% of subjects receiving indacaterol, 150 μg; indacaterol, 300 μg; and placebo, respectively. Serious adverse events occurred in 10.4%, 12.3%, and 10.5%, respectively. Indacaterol had no clinically significant effects on ECG findings (corrected QT interval) or on serum potassium or plasma glucose levels. Indacaterol increased trough FEV(1) relative to placebo throughout the study (difference of ≥ 170 mL at week 52). No tolerance to its bronchodilator effect was detected. Indacaterol treatment was accompanied by significant reductions in COPD exacerbations (rate ratios compared with placebo, 0.62-0.64; P indacaterol treatment, with decreases from baseline in mean total SGRQ score generally > 4 units. During 1 year of treatment, indacaterol was well tolerated and provided significant and well-maintained bronchodilation that was accompanied by improved clinical outcomes.

    In the absence of head-to-head clinical trials comparing the once-daily, long-acting beta2-agonists olodaterol and indacaterol for the treatment of chronic obstructive pulmonary disease (COPD), an indirect treatment comparison by systematic review and synthesis of the available clinical evidence was conducted. A systematic literature review of randomized, controlled clinical trials in patients with COPD was performed to evaluate the efficacy and safety of olodaterol and indacaterol. Network meta-analysis and adjusted indirect comparison methods were employed to evaluate treatment efficacy, using outcomes based on trough forced expiratory volume in 1 second (FEV1), Transition Dyspnea Index, St George's Respiratory Questionnaire total score and response, rescue medication use, and proportion of patients with exacerbations. Eighteen trials were identified for meta-analysis (eight, olodaterol; ten, indacaterol). Olodaterol trials included patients of all severities, whilst indacaterol trials excluded patients with very severe COPD. Concomitant maintenance bronchodilator use was allowed in most olodaterol trials, but not in indacaterol trials. When similarly designed trials/data were analyzed for change from baseline in trough FEV1 (liters), the following mean differences (95% confidence interval) were observed: trials excluding concomitant bronchodilator: indacaterol 75 mcg versus olodaterol 5 mcg, -0.005 (-0.077 to 0.067), and indacaterol 150 mcg versus olodaterol 5 mcg, 0.020 (-0.036 to 0.077); trials with concomitant tiotropium: indacaterol 150 mcg versus olodaterol 5 mcg, 0.000 (-0.043 to 0.042). In sensitivity analyses of the full network, results for change from baseline in trough FEV1 favored indacaterol, but this dataset suffered from trial design heterogeneity. For the other endpoints investigated, no statistically significant differences were found when analyzed in the full network. When compared under similar trial conditions, olodaterol and indacaterol have

    Inhaled glucocorticoid (ICS)/long-acting β2 -adrenoceptor agonist (LABA) combination therapy is a recommended treatment option for patients with moderate/severe asthma in whom adequate control cannot be achieved by an ICS alone. Previously, we discovered that LABAs can augment dexamethasone-inducible gene expression and proposed that this effect may explain how these two drugs interact to deliver superior clinical benefit. Herein, we extended that observation by analysing, pharmacodynamically, the effect of the LABA, indacaterol, on glucocorticoid receptor (GR)-mediated gene transcription induced by seven ligands with intrinsic activity values that span the spectrum of full agonism to antagonism. BEAS-2B human airway epithelial cells stably transfected with a 2× glucocorticoid response element luciferase reporter were used to model gene transcription together with an analysis of several glucocorticoid-inducible genes. Indacaterol augmented glucocorticoid-induced reporter activation in a manner that was positively related to the intrinsic activity of the GR agonist. This effect was demonstrated by an increase in response maxima without a change in GR agonist affinity or efficacy. Indacaterol also enhanced glucocorticoid-inducible gene expression. However, the magnitude of this effect was dependent on both the GR agonist and the gene of interest. These data suggest that indacaterol activates a molecular rheostat, which increases the transcriptional competency of GR in an agonist- and gene-dependent manner without apparently changing the relationship between fractional GR occupancy and response. These findings provide a platform to rationally design ICS/LABA combination therapy that is based on the generation of agonist-dependent gene expression profiles in target and off-target tissues. © 2015 The British Pharmacological Society.

    Full Text Available Inhaled, long-acting beta-2-adrenoceptor agonists (LABA have well-established roles in asthma and/or COPD treatment. Drug utilisation patterns for LABA have been described, but few studies have directly compared LABA use in different countries. We aimed to compare the prevalence of LABA-containing prescriptions in five European countries using a standardised methodology.A common study protocol was applied to seven European healthcare record databases (Denmark, Germany, Spain, the Netherlands (2, and the UK (2 to calculate crude and age- and sex-standardised annual period prevalence rates (PPRs of LABA-containing prescriptions from 2002-2009. Annual PPRs were stratified by sex, age, and indication (asthma, COPD, asthma and COPD.From 2002-2009, age- and sex-standardised PPRs of patients with LABA-containing medications increased in all databases (58.2%-185.1%. Highest PPRs were found in men ≥ 80 years old and women 70-79 years old. Regarding the three indications, the highest age- and sex-standardised PPRs in all databases were found in patients with "asthma and COPD" but with large inter-country variation. In those with asthma or COPD, lower PPRs and smaller inter-country variations were found. For all three indications, PPRs for LABA-containing prescriptions increased with age.Using a standardised protocol that allowed direct inter-country comparisons, we found highest rates of LABA-containing prescriptions in elderly patients and distinct differences in the increased utilisation of LABA-containing prescriptions within the study period throughout the five European countries.

    To contextualize young women's knowledge and attitudes regarding contraception at the outset of an intervention promoting long-acting reversible contraceptive (LARC) use for teen pregnancy prevention. Our intervention was on the basis of diffusion of innovation theory, and at the outset we were interested in likely early adopters' existing knowledge and attitudes toward contraception. This mixed methods study consisted of focus groups within positive youth development programs in Rochester, New York; we discussed young women's knowledge and sources of information for all US Food and Drug Administration-approved contraceptive methods. Seven focus groups and 24 female adolescent participants aged 15-19 years. Quantitative ranking of all contraceptive methods; qualitative themes from focus group discussions. Our findings showed a high level of knowledge about a select group of methods, which included LARC methods, and that participants received contraceptive information from peers and family. Participants had more concerns than positive impressions regarding the effectiveness, safety, practicality, and partner reception of the contraceptive methods, with the exception of the condom. Quantitatively, the condom received the highest average rating. The importance of personal anecdotes in our findings supports the use of outreach and information campaigns; providing medically accurate information and spreading positive personal anecdotes will be key to improving young women's impressions of the safety and acceptability of LARC use. This snapshot of contraceptive knowledge indicates that young women can be mature, informed consumers of sexual and reproductive health care, and through diffusion of innovation could be key players in promoting the most effective means of pregnancy prevention.

    Full Text Available Abstract Background Well-differentiated neuroendocrine carcinomas are highly vascularized and may be sensitive to drugs administered on a metronomic schedule that has shown antiangiogenic properties. A phase II study was designed to test the activity of protracted 5-fluorouracil (5FU infusion plus long-acting release (LAR octreotide in patients with neuroendocrine carcinoma. Methods Twenty-nine patients with metastatic or locally advanced well-differentiated neuroendocrine carcinoma were treated with protracted 5FU intravenous infusion (200 mg/m2 daily plus LAR octreotide (20 mg monthly. Patients were followed for toxicity, objective response, symptomatic and biochemical response, time to progression and survival. Results Assessment by Response Evaluation Criteria in Solid Tumors (RECIST criteria showed partial response in 7 (24.1%, stable disease in 20 (69.0%, and disease progression in 2 patients. Response did not significantly differ when patients were stratified by primary tumor site and proliferative activity. A biochemical (chromogranin A response was observed in 12/25 assessable patients (48.0%; symptom relief was obtained in 9/15 symptomatic patients (60.0%. There was non significant decrease in circulating vascular epithelial growth factor (VEGF over time. Median time to progression was 22.6 months (range, 2.7-68.5; median overall survival was not reached yet. Toxicity was mild and manageable. Conclusion Continuous/metronomic 5FU infusion plus LAR octreotide is well tolerated and shows activity in patients with well-differentiated neuroendocrine carcinoma. The potential synergism between metronomic chemotherapy and antiangiogenic drugs provides a rationale for exploring this association in the future. Trial registration NCT00953394

    The effects of pituitary suppression with one-third depot of long-acting gonadotropin-releasing hormone (GnRH) agonist in GnRH agonist long protocol for in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) were investigated. A retrospective cohort study was performed on 3186 cycles undergoing IVF/ICSI with GnRH agonist long protocol in a university-affiliated infertility center. The pituitary was suppressed with depot triptorelin of 1.25 mg or 1.875 mg. There was no significant difference in live birth rate between 1.25 mg triptorelin group and 1.875 mg triptorelin group (41.2% vs. 43.7%). The mean luteinizing hormone (LH) level on follicle-stimulating hormone (FSH) starting day was significantly higher in 1.25 mg triptorelin group. The mean LH level on the day of human chorionic gonadotrophin (hCG) administration was slightly but statistically higher in 1.25 mg triptorelin group. There was no significant difference in the total FSH dose between the two groups. The number of retrieved oocytes was slightly but statistically less in 1.25 mg triptorelin group than in 1.875 mg triptorelin group (12.90±5.82 vs. 13.52±6.97). There was no significant difference in clinical pregnancy rate between the two groups (50.5% vs. 54.5%). It was suggested that one-third depot triptorelin can achieve satisfactory pituitary suppression and produce good live birth rates in a long protocol for IVF/ICSI.

    Full Text Available Yuji Oba, Nazir A Lone University of Missouri, School of Medicine, Division of Pulmonary, Critical Care and Environmental Medicine, Columbia, MO, USA Background: A combination therapy with inhaled corticosteroid (ICS and a long-acting beta agonist (LABA is recommended in severe chronic obstructive pulmonary disease (COPD patients experiencing frequent exacerbations. Currently, there are five ICS/LABA combination products available on the market. The purpose of this study was to systematically review the efficacy of various ICS/LABA combinations with a network meta-analysis. Methods: Several databases and manufacturer's websites were searched for relevant clinical trials. Randomized control trials, at least 12 weeks duration, comparing an ICS/LABA combination with active control or placebo were included. Moderate and severe exacerbations were chosen as the outcome assessment criteria. The primary analyses were conducted with a Bayesian Markov chain Monte Carlo method. Results: Most of the ICS/LABA combinations reduced moderate-to-severe exacerbations as compared with placebo and LABA, but none of them reduced severe exacerbations. However, many studies excluded patients receiving long-term oxygen therapy. Moderate-dose ICS was as effective as high-dose ICS in reducing exacerbations when combined with LABA. Conclusion: ICS/LABA combinations had a class effect with regard to the prevention of COPD exacerbations. Moderate-dose ICS/LABA combination therapy would be sufficient for COPD patients when indicated. The efficacy of ICS/LABA combination therapy appeared modest and had no impact in reducing severe exacerbations. Further studies are needed to evaluate the efficacy of ICS/LABA combination therapy in severely affected COPD patients requiring long-term oxygen therapy. Keywords: combination therapy

    Combined inhaled therapy in chronic obstructive pulmonary disease (COPD) is commonly used, but its benefits remain controversial. We assessed the effect of tiotropium in reducing COPD exacerbations when combined with long-acting β2 agonists (LABA) and/or inhaled corticosteroids (ICS). This new-user cohort study is based on administrative data from 3 Italian regions. We identified adults hospitalized for COPD from 2006 to 2009 who were newly prescribed a fixed LABA/ICS combination (double therapy). We classified patients according to whether tiotropium was also prescribed (triple therapy), using both intention-to-treat and as-treated approaches, and followed them for 1 year. COPD exacerbations were measured as outcomes. Multivariate and propensity score-adjusted hazard ratios (HRs, 95%CI) were calculated with Cox regression models. We identified 5717 new users of LABA/ICS of which 31.9% initiated triple therapy. In the intention-to-treat analysis, the multivariate adjusted HR for moderate, severe, and any exacerbations were 1.02 (95%CI 0.89-1.16), 0.92 (95%CI 0.76-1.12), and 1.08 (95%CI 0.91-1.28), respectively. The propensity score adjustment produced similar results. In the subcohort of patients with previous exacerbations, triple therapy was significantly associated with reduced risk of moderate exacerbations, compared to double therapy (HR 0.68, 95%CI 0.48-0.98 in intention-to-treat approach). In conclusion, the addition of tiotropium to LABA/ICS did not reduce COPD exacerbations compared to LABA/ICS alone. A protective role for moderate exacerbations was found in patients at risk of frequent exacerbations. Given the impact of exacerbations on health status and prognosis, it is crucial to target COPD patients for optimal treatment.

    MOD-4023 is a novel long-acting version of human growth hormone (hGH), containing the carboxy-terminal peptide (CTP) of human chorionic gonadotropin (hCG). MOD-4023 is being developed as a treatment for adults and children with growth hormone deficiency (GHD), which would require fewer injections than currently available GH formulations and thus reduce patient discomfort and increase compliance. This study characterizes MOD-4023's binding affinities for the growth hormone receptor, as well as the pharmacokinetic and pharmacodynamics, toxicology, and safety profiles of repeated dosing of MOD-4023 in Sprague-Dawley rats and Rhesus monkeys. Although MOD-4023 exhibited reduced in vitro potency and lower affinity to the GH receptor than recombinant hGH (rhGH), administration of MOD-4023 every 5 days in rats and monkeys resulted in exposure comparable to daily rhGH, and the serum half-life of MOD-4023 was significantly longer. Repeated administration of MOD-4023 led to elevated levels of insulin-like growth factor 1 (IGF-1), and twice-weekly injections of MOD-4023 resulted in larger increase in weight gain with fewer injections and a lower accumulative hGH dose. Thus, the increased half-life of MOD-4023 in comparison to hGH may increase the frequency of protein-receptor interactions and compensate for its decreased in vitro potency. MOD-4023 was found to be well-tolerated in rats and monkeys, with minimal adverse events, suggesting an acceptable safety profile. These results provide a basis for the continued clinical development of MOD-4023 as a novel treatment of GHD in children and adults.

    Abstract In view of the forthcoming long-acting antiretrovirals, measures should be taken to prevent the selection of HIV drug resistance mutations. All subjects who had been switched to boosted protease inhibitors plus maraviroc (bPIs/MVC) with baseline HIV-1 RNA >50 copies/mL between June, 2014, and April, 2015, were retrospectively evaluated. HIV-1 RNA, CD4+ T-cells, serum glucose, creatinine, ALT, and adverse events were controlled every 3 to 4 months. We retrospectively analyzed 44 patients: 18 were taking darunavir/ritonavir (DRV/r) and 26 atazanavir/ritonavir (ATV/r) once daily, plus MVC 300 mg once daily. Seven subjects were in CDC stage C. All had a follow-up of at least 24 weeks, 28 exceeded 48 weeks, and 21 exceeded 72 weeks. All had experienced at least 1 viral failure and had selected at least 1 resistance-associated mutation (RAM). At baseline, 38 had plasma HIV-1 RNA 50-499 copies/mL and 6 had ≥500. At week 24, none had viremia >500 and 30 (68.2%) had suppressed HIV-1 RNA below 50 copies/mL. Of the subgroup with 48 weeks’ follow-up, 23 had HIV-1 RNA 50-499 copies/mL, 5 had ≥500, and 20/28 suppressed to <50 copies/mL. Of the longest observed subgroup (72 weeks), 17 had HIV-1 RNA 50-499 copies/mL, and 4 had ≥500 copies/mL and 15/21 (71.4%) suppressed to <50 copies/mL. This combination allowed fair suppression of viral replication, with minor genotypic evolution in 6 subjects, and seems to be a feasible strategy to prevent damaging future options. PMID:28207500

    Diabetes mellitus is generally controlled quite well with the administration of oral medications or by the use of insulin injections. The current practice is the use of one or more doses, intermediate or long acting insulin per day. Oral insulin is a promising yet experimental method providing tight glycemic control for patients with diabetes. A biologically adhesive delivery systems offer important advantage over conventional drug delivery systems. The engineered polymer microspheres made of erodable polymer display strong adhesive interactions with gastrointestinal mucus and cellular lining can traverse both the mucosal epithelium and the follicle associated epithelium covering the lymphoid tissue of Peyer's patches. Alginate, a natural polymer recovered from seaweed is being developed as a nanoparticle for the delivery of insulin without being destroyed in the stomach. Alginate is in fact finding application in biotechnology industry as thickening agent, a gelling agent and a colloid stabilizer. Alginate has in addition, several other properties that have enabled it to be used as a matrix for entrapment and for the delivery of a variety of proteins such as insulin and cells. These properties include: a relatively inert aqueous environment within the matrix; a mild room temperature encapsulation process free of organic solvents; a high gel porosity which allows for high diffusion rates of macromolecules; the ability to control this porosity with simple coating procedures and dissolution and biodegradation of the system under normal physiological conditions.

    Directory of Open Access Journals (Sweden)

    Marc Nischang

    Full Text Available BACKGROUND: Humanized mice generate a lymphoid system of human origin subsequent to transplantation of human CD34+ cells and thus are highly susceptible to HIV infection. Here we examined the efficacy of antiretroviral treatment (ART when added to food pellets, and of long-acting (LA antiretroviral compounds, either as monotherapy or in combination. These studies shall be inspiring for establishing a gold standard of ART, which is easy to administer and well supported by the mice, and for subsequent studies such as latency. Furthermore, they should disclose whether viral breakthrough and emergence of resistance occurs similar as in HIV-infected patients when ART is insufficient. METHODS/PRINCIPAL FINDINGS: NOD/shi-scid/γ(cnull (NOG mice were used in all experimentations. We first performed pharmacokinetic studies of the drugs used, either added to food pellets (AZT, TDF, 3TC, RTV or in a LA formulation that permitted once weekly subcutaneous administration (TMC278: non-nucleoside reverse transcriptase inhibitor, TMC181: protease inhibitor. A combination of 3TC, TDF and TMC278-LA or 3TC, TDF, TMC278-LA and TMC181-LA suppressed the viral load to undetectable levels in 15/19 (79% and 14/14 (100% mice, respectively. In successfully treated mice, subsequent monotherapy with TMC278-LA resulted in viral breakthrough; in contrast, the two LA compounds together prevented viral breakthrough. Resistance mutations matched the mutations most commonly observed in HIV patients failing therapy. Importantly, viral rebound after interruption of ART, presence of HIV DNA in successfully treated mice and in vitro reactivation of early HIV transcripts point to an existing latent HIV reservoir. CONCLUSIONS/SIGNIFICANCE: This report is a unique description of multiple aspects of HIV infection in humanized mice that comprised efficacy testing of various treatment regimens, including LA compounds, resistance mutation analysis as well as viral rebound after treatment

    Chronic obstructive pulmonary disease (COPD) is a slowly progressive, largely non-reversible pulmonary disease which is characterised by airflow limitation. It is one of the few diseases with an increasing mortality rate and by 2020 it is predicted to be the third leading cause of death. The mainstays of current treatment are long acting β₂ agonists (LABAs) coupled with an increasing reliance on inhaled corticosteroids (ICS). Two LABAs (salmeterol and formoterol) are currently licensed for COPD both as monotherapy and in combination with ICS (fluticasone propionate (FP) and budesonide respectively). A comprehensive review of the risk-benefit of these medicines in COPD is provided here which concludes that there is limited efficacy for LABAs in COPD either alone or in combination with ICS and no overall modification of the disease process. However, where directly compared, combination therapy usually provides an advantage over monotherapy. Importantly the apparent effectiveness of treatment may significantly depend upon the outcome measure chosen with some measures possibly underestimating the extent of benefit. ICS benefit may also be greater in those patients who respond to treatment. Set against this benefit are recent concerns that a number of issues related to the clinical trial design such as prior use of ICS and different withdrawal rates between groups may be significantly influencing results. Furthermore there is no evidence of a dose response relationship with regard to ICS dose. A key issue with combination therapy is the excess risk of pneumonia conferred by the use of an ICS in this patient population. This risk does not appear to be proportional to the ICS dose but may differ between FP and budesonide. We conclude that further studies are required to identify the optimal dose of ICS, in terms of both risk and benefit, and to confirm their benefit in steroid naïve patients. Furthermore it will be important to determine whether the risk of pneumonia

    Strategic applications of long-acting acaricides for the control of Rhipicephalus (Boophilus) microplus in northwestern Argentina were evaluated for one year. In addition, tick distribution among cattle was analyzed to evaluate if partial selective treatment or culling the small proportion of most heavily infested animals were feasible options to control R. (B.) microplus. Two different treatments schemes based on two applications of fluazuron and one application of 3.15% ivermectin were performed. Treatments were made in late winter and spring so as to act on the small 1st spring generation of R. (B.) microplus, in order to preclude the rise of the larger autumn generation. The overall treatment effect was positively significant in both schemes. The number of ticks observed in the control group was significantly higher than in the treated groups on all post-treatment counts. Group 2 exhibited more than 80% of efficacy almost throughout the study period, whereas Group 1 exhibited an efficacy percentage higher than 80% in September, October, December, February, April and May, but not in November (73.4%), January (58.3%), March (45.2%) or June (53.4%). Absolute control was observed in Group 2 in the counts of September and October, and in Group 1 in the count of February. The control strategies evaluated in this work provide an acceptable control level with only three applications of acaricides; at the same time, they prevent the occurrence of the autumn peak of tick burdens, which is characteristic of R. (B.) microplus in northwestern Argentina. Tick distribution was markedly aggregated in all counts. Although ticks were not distributed evenly among calves, the individual composition of the most heavily infested group was not consistent throughout the study period. In addition, the level of aggregation varied with tick abundance. These results suggest that applying acaricides to a portion of the herd or culling the most infested individuals at a given moment of the

    Objective: To evaluate the cost-effectiveness of octreotide long acting release (LAR) vs lanreotide slow release (SR) for the treatment of postoperative acromegalic patients with elevated levels of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) in China. Methods: A decision tree model was constructed and the treatment impact was projected for one year in Chinese setting. The clinical efficacy measure used was the percentage of patients achieving normalization (control) of either IGF-1 or GH levels. Efficacy of octreotide LAR and lanreotide SR, incidence of comorbidities, impact of acromegaly on health-related quality of life, and drug-related side effects data were obtained from literature. The cost of medication was collected through a chart review from five hospitals in five cities of China. Clinical experts from these hospitals were requested to complete a questionnaire to document the utilization of medical resources, costs of comorbidities, side effects as well as cost of administration. One-way sensitivity analysis was performed to evaluate the robustness of the results. Results: Compared to lanreotied SR group, the percentage of patients achieving normalization of IGF-1 and GH levels of octreotide LAR group were 10% and 9% higher, respectively. When either IGF-1 or GH control were used as the efficacy measure, patients in the octreotide LAR group exhibit less comorbidities and need less continued treatment with a second operation and radiotherapy than those in lanreotide SR group. When IGF-1 was used as efficacy measure, octreotide LAR not only achieved better efficacy but resulted in overall cost-saving, with a total cost savings of ¥ 3 792 per patient for one year, which demonstrated that octreotide LAR was a dominant cost-saving strategy. When GH control was used as the efficacy measure, octreotide LAR achieved a better overall clinical efficacy with a slightly higher total costs (¥ 4 121 higher per patient per year). Sensitivity

This post hoc analysis of data from an international observational study aimed to investigate the efficacy and tolerability of long-acting nifedipine (30 mg or 60 mg; monotherapy or in combination in the Middle Eastern and Moroccan populations defined as having high cardiovascular risk. Methods: This was a prospective, noninterventional, multicenter observational study. Observations from patients (aged ≥ 18 years with treated or untreated hypertension from the Middle East (Jordan, Saudi Arabia, Kuwait, Lebanon, Qatar, United Arab Emirates, and Yemen and Morocco are presented. Hypertension grade and cardiovascular risk were defined at baseline, and systolic/diastolic BP change was defined at post-baseline visits (≤3. Adverse events and ratings of therapy efficacy and patient/physician satisfaction were recorded. Results: The study included 1466 patients from the Middle East and 524 from Morocco. Characteristics of the populations differed, with a more severe hypertension profile in Moroccan patients. Despite these differences, nifedipine reduced BP to a similar extent in each group, with efficacy dependent on cardiovascular risk factors such as hypertension grade and age. Few adverse

    Unplanned pregnancy remains a common problem in many resource-limited settings, mostly due to limited access to modern family planning (FP) services. In particular, use of the more effective long-acting reversible contraceptive (LARC) methods (i.e., intrauterine devices and hormonal implants) remains low compared to the short-acting methods (i.e., condoms, hormonal pills, injectable hormones, and spermicides). Among reproductive-age women attending FP and antenatal care clinics in Uganda, we assessed perceptions and practices regarding the use of modern contraceptive methods. We specifically aimed to evaluate factors influencing method selection. We performed a mixed-methods cross-sectional study, in which we administered structured interviews to 180 clients, and conducted 4 focus group discussions (FGDs) with 36 clients and 8 in-depth personal qualitative interviews with health service providers. We summarized quantitative data and performed latent content analysis on transcripts from the FGDs and qualitative interviews. The prevalence of ever use for LARC methods was 23%. Method characteristics (e.g., client control) appeared to drive method selection more often than structural factors (such as method availability) or individual client characteristics (such as knowledge and perceptions). The most common reasons for choosing LARC methods were: longer protection; better child-spacing; and effectiveness. The most common reasons for not choosing LARC methods included requiring a client-controlled method and desiring to conceive in the near future. The most common reasons for choosing short-acting methods were ease of access; lower cost; privacy; perceived fewer side effects; and freedom to stop using a method without involving the health provider. The personal characteristics of clients, which appeared to be important were client knowledge and number of children. The structural factor which appeared to be important was method availability. Our results suggest that

    this analysis aims to explore midwives' insights into the provision of long-acting and permanent methods of contraception (LAPMs) in the selected areas of East Java and Nusa Tenggara Barat (NTB) Provinces, Indonesia. a qualitative study using in-depth interviews was conducted with 12 village midwives from 12 villages, to explore their perceptions and experiences in delivering family planning services. the study was carried out in May-June 2013, as part of the baseline assessment in the Improving Contraceptive Method Mix (ICMM) study. We interviewed 12 village midwives working in 12 villages in six study districts: Tuban, Kediri, and Lumajang Districts in East Java Province; and Lombok Barat, Lombok Timur, and Sumbawa Districts in NTB Province. an interview guideline was used in all interviews. It covered several topics, such as community perceptions of LAPMs, availability of contraception and related equipment, availability of human resources, and midwives' efforts to improve LAPM coverage. All interviews were recorded and transcribed. Content and thematic analyses were carried out by grouping and coding the information based on the identified themes and topics. according to village midwives interviewed in this study, community-level acceptance of LAPMs has increased over time; however, some still prefer using short-acting methods for a long period. The reasons include lack of awareness about the benefits and side effects of LAPMs, fear of surgical procedures, rumored consequences (for example, that LAPMs would limit women's ability to perform hard physical labor), and religious beliefs. There were several challenges reported by village midwives in delivering LAPM services, such as confusion about midwives' eligibility to provide LAPM services, lack of Contraceptive Technology Update (CTU) and counseling trainings, and shortage of supporting equipment (such as exam tables and IUD and implant insertion kits). There were several strategies implemented by village

    Full Text Available Histoplasmosis is a systemic fungal disease that takes various clinical forms, among which oral lesions are rare. The disseminated form of the disease that usually occurs in association with Human Immunodeficiency Virus (HIV is one of the AIDS-defining diseases. Isolated oral histoplasmosis, without systemic involvement, with underlying immunosuppression due to AIDS is very rare. We report one such case of isolated oral histoplasmosis in a HIV-infected patient.

    The pharmacological profile of a novel angiotensin II type 1 receptor blocker, azilsartan medoxomil, was compared with that of the potent angiotensin II receptor blocker olmesartan medoxomil. Azilsartan, the active metabolite of azilsartan medoxomil, inhibited the binding of [(125)I]-Sar(1)-I1e(8)-angiotensin II to angiotensin II type 1 receptors. Azilsartan medoxomil inhibited angiotensin II-induced pressor responses in rats, and its inhibitory effects lasted 24h after oral administration. The inhibitory effects of olmesartan medoxomil disappeared within 24h. ID(50) values were 0.12 and 0.55 mg/kg for azilsartan medoxomil and olmesartan medoxomil, respectively. In conscious spontaneously hypertensive rats (SHRs), oral administration of 0.1-1mg/kg azilsartan medoxomil significantly reduced blood pressure at all doses even 24h after dosing. Oral administration of 0.1-3mg/kg olmesartan medoxomil also reduced blood pressure; however, only the two highest doses significantly reduced blood pressure 24h after dosing. ED(25) values were 0.41 and 1.3mg/kg for azilsartan medoxomil and olmesartan medoxomil, respectively. In renal hypertensive dogs, oral administration of 0.1-1mg/kg azilsartan medoxomil reduced blood pressure more potently and persistently than that of 0.3-3mg/kg olmesartan medoxomil. In a 2-week study in SHRs, azilsartan medoxomil showed more stable antihypertensive effects than olmesartan medoxomil and improved the glucose infusion rate, an indicator of insulin sensitivity, more potently (≥ 10 times) than olmesartan medoxomil. Azilsartan medoxomil also exerted more potent antiproteinuric effects than olmesartan medoxomil in Wistar fatty rats. These results suggest that azilsartan medoxomil is a potent angiotensin II receptor blocker that has an attractive pharmacological profile as an antihypertensive agent.

    Oral disease is exceedingly common in small animal patients. In addition, there is a very wide variety of pathologies that are encountered within the oral cavity. These conditions often cause significant pain and/or localized and systemic infection; however, the majority of these conditions have little to no obvious clinical signs. Therefore, diagnosis is not typically made until late in the disease course. Knowledge of these diseases will better equip the practitioner to effectively treat them. This article covers the more common forms of oral pathology in the dog and cat, excluding periodontal disease, which is covered in its own chapter. The various pathologies are presented in graphic form, and the etiology, clinical signs, recommended diagnostic tests, and treatment options are discussed. Pathologies that are covered include: persistent deciduous teeth, fractured teeth, intrinsically stained teeth, feline tooth resorption, caries, oral neoplasia, eosinophilic granuloma complex, lymphoplasmacytic gingivostomatitis, enamel hypoplasia, and "missing" teeth.

    What is the contribution of the provision, at no cost for users, of long acting reversible contraceptive methods (LARC; copper intrauterine device [IUD], the levonorgestrel-releasing intrauterine system [LNG-IUS], contraceptive implants and depot-medroxyprogesterone [DMPA] injection) towards the disability-adjusted life years (DALY) averted through a Brazilian university-based clinic established over 30 years ago. Over the last 10 years of evaluation, provision of LARC methods and DMPA by the clinic are estimated to have contributed to DALY averted by between 37 and 60 maternal deaths, 315-424 child mortalities, 634-853 combined maternal morbidity and mortality and child mortality, and 1056-1412 unsafe abortions averted. LARC methods are associated with a high contraceptive effectiveness when compared with contraceptive methods which need frequent attention; perhaps because LARC methods are independent of individual or couple compliance. However, in general previous studies have evaluated contraceptive methods during clinical studies over a short period of time, or not more than 10 years. Furthermore, information regarding the estimation of the DALY averted is scarce. We reviewed 50 004 medical charts from women who consulted for the first time looking for a contraceptive method over the period from 2 January 1980 through 31 December 2012. Women who consulted at the Department of Obstetrics and Gynaecology, University of Campinas, Brazil were new users and users switching contraceptive, including the copper IUD (n = 13 826), the LNG-IUS (n = 1525), implants (n = 277) and DMPA (n = 9387). Estimation of the DALY averted included maternal morbidity and mortality, child mortality and unsafe abortions averted. We obtained 29 416 contraceptive segments of use including 25 009 contraceptive segments of use from 20 821 new users or switchers to any LARC method or DMPA with at least 1 year of follow-up. The mean (± SD) age of the women at first consultation ranged from 25

Forty-six subjects were randomized 1:1 to aripiprazole lauroxil 441 mg IM in the deltoid or gluteal muscle. Samples were collected through 89 days post-dose to measure levels of aripiprazole lauroxil, N-hydroxymethyl aripiprazole, aripiprazole, and dehydro-aripiprazole. Forty-three (93.5%) subjects completed all study assessments; most were CYP2D6 extensive or immediate metabolizers (96%); two (4%) were poor metabolizers. The PK of aripiprazole following aripiprazole lauroxil was characterized by a steady rise in plasma concentrations (Tmax 44-50 days), a broad peak, and prolonged exposure attributable to the dissolution of aripiprazole lauroxil and formation rate-limited elimination of aripiprazole (t1/2=15.4-19.2 days). Deltoid vs. gluteal administration resulted in slightly higher Cmax aripiprazole concentrations [1.31 (1.02, 1.67); GMR 90% CI]; total exposure (AUCinf) was similar between sites of administration [0.84 (0.57, 1.24)]. N-hydroxymethyl-aripiprazole and dehydro-aripiprazole exposures were 10% and 33-36%, respectively, of aripiprazole exposure following aripiprazole lauroxil. The most common adverse events were injection site pain in 20 subjects (43.5%) and headache in 6 subjects (13.0%) of mild intensity occurring at a similar rate with deltoid and gluteal administration. Exposure ranges with deltoid and gluteal administration overlapped, suggesting that these sites may be used interchangeably. Despite a higher incidence of adverse events, deltoid muscle provides a more accessible injection site and could facilitate patient acceptance.

    AP is a major cause of morbidity and mortality in elderly patients, especially frail elderly patients. The aim of this article is to review effect of oral care, including oral hygiene and improvement of oral function, on the prevention of AP among elderly people in hospitals and nursing homes. There is now a substantial body of work studying the effect of oral care on the prevention of respiratory diseases. Oral hygiene, consisting of oral decontamination and mechanical cleaning by dental professionals, has resulted in significant clinical effects (decreased incidence of pneumonia and decreased mortality from respiratory diseases) in clinical randomized trials. Moreover, studies examining oral colonization by pneumonia pathogens have shown the effect of oral hygiene on eliminating these pathogens. In addition, swallowing training has been shown to improve the movement and function of swallowing-related muscles, also resulting in decreased incidence of pneumonia. These findings support the contention that oral care is effective in the prevention of AP.

    Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options.

    2017-01-01

    Objective: The aim of the present study was to determine whether a combination of anti-HIV drugs – tenofovir (TFV), lopinavir (LPV) and ritonavir (RTV) – in a lipid-stabilized nanosuspension (called TLC-ART101) could enhance and sustain intracellular drug levels and exposures in lymph node and blood cells above those in plasma. Design: Four macaques were given a single dose of TLC-ART101 subcutaneously. Drug concentrations in plasma and mononuclear cells of the blood (PBMCs) and lymph nodes (LNMCs) were analysed using a validated combination LC-MS/MS assay. Results: For the two active drugs (TFV, LPV), plasma and PBMC intracellular drug levels persisted for over 2 weeks; PBMC drug exposures were three- to four-fold higher than those in plasma. Apparent terminal half-lives (t1/2) of TFV and LPV were 65.3 and 476.9 h in plasma, and 169.1 and 151.2 h in PBMCs. At 24 and 192 h, TFV and LPV drug levels in LNMCs were up to 79-fold higher than those in PBMCs. Analysis of PBMC intracellular TFV and its active metabolite TFV-diphosphate (TFV-DP) indicated that intracellular exposures of total TFV and TFV-DP were markedly higher and persisted longer than in humans and macaques dosed with oral TFV prodrugs, tenofovir disoproxil fumarate (TDF) or tenofovir alafenamide (TAF). Conclusions: A simple, scalable three-drug combination, lipid-stabilized nanosuspension exhibited persistent drug levels in cells of lymph nodes and the blood (HIV host cells) and in plasma. With appropriate dose adjustment, TLC-ART101 may be a useful HIV treatment with a potential to impact residual virus in lymph nodes. PMID:28099191

    Full Text Available Ronald C Hamdy,1,2 Dane N Daley11Osteoporosis Center, College of Medicine, East Tennessee State University, 2Veterans Affairs Medical Center, Johnson City, TN, USAAbstract: Calcitonin is a hormone secreted by the C-cells of the thyroid gland in response to elevations of the plasma calcium level. It reduces bone resorption by inhibiting mature active osteoclasts and increases renal calcium excretion. It is used in the management of postmenopausal osteoporosis, Paget's disease of bone, and malignancy-associated hypercalcemia. Synthetic and recombinant calcitonin preparations are available; both have similar pharmacokinetic and pharmacodynamic profiles. As calcitonin is a peptide, the traditional method of administration has been parenteral or intranasal. This hinders its clinical use: adherence with therapy is notoriously low, and withdrawal from clinical trials has been problematic. An oral formulation would be more attractive, practical, and convenient to patients. In addition to its effect on active osteoclasts and renal tubules, calcitonin has an analgesic action, possibly mediated through β-endorphins and the central modulation of pain perception. It also exerts a protective action on cartilage and may be useful in the management of osteoarthritis and possibly rheumatoid arthritis. Oral formulations of calcitonin have been developed using different techniques. The most studied involves drug-delivery carriers such as Eligen® 8-(N-2hydroxy-5-chloro-benzoyl-amino-caprylic acid (5-CNAC (Emisphere Technologies, Cedar Knolls, NJ. Several factors affect the bioavailability and efficacy of orally administered calcitonin, including amount of water used to take the tablet, time of day the tablet is taken, and proximity to intake of a meal. Preliminary results looked promising. Unfortunately, in two Phase III studies, oral calcitonin (0.8 mg with 200 mg 5-CNAC, once a day for postmenopausal osteoporosis and twice a day for osteoarthritis failed to

    Probiotics, i.e., bacteria expressing therapeutic peptides (protein), are used as a new type of orally ad-ministrated biologic drugs to treat diseases. To develop yeast strains which could effectively prevent and treat type 2 diabetes mellitus, we firstly constructed the yeast integrating plasmid pNK1-PGK which could successfully express green fluorescent protein (GFP) in Saccharomyces cerevisiae. The gene encoding ten tandem repeats of glucagon-like peptide-1(10×GLP-1) was cloned into the vector pNK1-PGK and the resulting plasmids were then transformed into the S. cerevisiae INVSc1. The long-acting GLP-1 hypoglycemic yeast (LHY) which grows rapidly and expresses 10×GLP-1 stably was selected by nutrition screening and Western blotting. The amount of 10×GLP-1 produced by LHY reached 1.56 mg per gram of wet cells. Moreover, the oral administration of LHY significantly reduced blood glucose level in type 2 diabetic mice induced by streptozotocin plus high fat and high sugar diet.%益生菌生物药物是指通过口服表达药用多肽(蛋白)的重组益生菌活细胞达到治疗疾病的新型口服给药系统。为了构建一种能有效防治2型糖尿病的酵母生物药物,文章首先构建了酿酒酵母(S.cerevisiae)整合型表达载体pNK1-PGK,并且通过绿色荧光蛋白(GFP)证明其表达功能正常,利用该载体将10×GLP-1(Glucagon-like peptide-1)基因转化到酿酒酵母INVSc1中,通过营养缺陷型和Western blotting成功筛选出表达10×GLP-1的长效促胰岛素降糖酵母(Long-acting GLP-1 hypoglycemic yeast, LHY)。该酵母生长迅速,外源基因10×GLP-1表达稳定,表达量达到1.56 mg/g细胞湿重。通过链脲佐菌素和高脂高糖饮食联合诱导的方法构建了2型糖尿病小鼠模型,用LHY对其进行口服灌胃治疗,证明LHY具有较好疗效,明显降低血糖水平。

    Full Text Available Abstract Background The prevention of unintended pregnancies among HIV positive women is a neglected strategy in the fight against HIV/AIDS. Women who want to avoid unintended pregnancies can do this by using a modern contraceptive method. Contraceptive choice, in particular the use of long acting and permanent methods (LAPMs, is poorly understood among HIV-positive women. This study aimed to compare factors that influence women's choice in contraception and women's knowledge and attitudes towards the IUD and female sterilization by HIV-status in a high HIV prevalence setting, Cape Town, South Africa. Methods A quantitative cross-sectional survey was conducted using an interviewer-administered questionnaire amongst 265 HIV positive and 273 HIV-negative postpartum women in Cape Town. Contraceptive use, reproductive history and the future fertility intentions of postpartum women were compared using chi-squared tests, Wilcoxon rank-sum and Fisher's exact tests where appropriate. Women's knowledge and attitudes towards long acting and permanent methods as well as factors that influence women's choice in contraception were examined. Results The majority of women reported that their most recent pregnancy was unplanned (61.6% HIV positive and 63.2% HIV negative. Current use of contraception was high with no difference by HIV status (89.8% HIV positive and 89% HIV negative. Most women were using short acting methods, primarily the 3-monthly injectable (Depo Provera. Method convenience and health care provider recommendations were found to most commonly influence method choice. A small percentage of women (6.44% were using long acting and permanent methods, all of whom were using sterilization; however, it was found that poor knowledge regarding LAPMs is likely to be contributing to the poor uptake of these methods. Conclusions Improving contraceptive counselling to include LAPM and strengthening services for these methods are warranted in this setting

    Over 60 million women use highly efficient and safe modern combined oral contraceptives (OCs) every day. A women who takes the oral contraceptive for 5 years before the age of 30 will actually live 12 days longer, although a woman taking the pill for the 1st time for 5 years after the age of 30 will have her life span reduced on the average by 80 days. OC related morbidity and mortality mostly occur in women over 35 who smoke. Combined low dose OCs are safe for women who do not smoke, at least to 45 years of age and probably to the menopause. The prescription of OCs is also safe to the young adolescent. The pill does not interfere with maturation of the hypothalamic-pituitary ovarian axis and does not increase the incidence of amenorrhoea, oligomenorrhoea or infertility in later life. Patients with contraindications to estrogen therapy are excluded from OC use (history of thromboembolism, major heart disease, liver disease, breast cancer). Low-dose (30-35 mcg estrogen-containing monophasic or triphasic) pills are recommended. Combined oral contraceptives contain either ethinyl estradiol (1.7 to 2 times more potent) or mestranol. After absorption the progestagens, norethisterone acetate, ethynodiol diacetate and lynoestrenol are all metabolized to norethisterone. The progestagen-only pill has about a 2% failure rate and poorer cycle control than the combined pill, but it lacks estrogenic, progestagenic and androgenic side effects. This pill is suitable for the lactating mother, for smokers over 35, for hypertensive patients, and for those with a history of thrombosis. The efficacy of the progestagen-only pill is restored in 3 days of pill taking. Postcoital contraception is an alternative: treatment can be given for at least 72 hours after intercourse. The Yuzpe method calls for the patient to take 2 combined oral contraceptive tablets containing levonorgestrel and ethinyl estradiol (Eugynon or Ovral) followed by a further 2 tablets 12 hours later.

    2014-06-01

    Restricted mouth opening (RMO) and trismus are terms commonly used in oral oncology in instances where there is difficulty in mouth opening. The term trismus in oral oncology is mainly used to indicate the radiation-induced fibrosis of the muscles of mastication. The treatment given for RMO as reported in the literature is given for muscular dysfunction trismus, whereas RMO in oral oncology can occur owing to various reasons other than muscular dysfunction. RMO occurs in various conditions of the oral cavity; in posterior pharyngeal infection, where it is termed reflectory trismus; in oral submucous fibrosis; in oral mucosal disorders; in the use of certain drugs; and in minor dental procedures of the posterior oral cavity. The usage of the term trismus in all RMO cases would complicate the treatment; thus, the word should not be used in all RMO cases.

    On the basis of strong research evidence, Duchenne muscular dystrophy (DMD), the most common severe childhood form of muscular dystrophy, is an X-linked recessive disorder caused by out-of-frame mutations of the dystrophin gene. Thus, it is classified asa dystrophinopathy. The disease onset is before age 5 years. Patients with DMD present with progressive symmetrical limb-girdle muscle weakness and become wheelchair dependent after age 12 years. (2)(3). On the basis of some research evidence,cardiomyopathy and congestive heart failure are usually seen in the late teens in patients with DMD. Progressive scoliosis and respiratory in sufficiency often develop once wheelchair dependency occurs. Respiratory failure and cardiomyopathy are common causes of death, and few survive beyond the third decade of life. (2)(3)(4)(5)(6)(7). On the basis of some research evidence, prednisone at 0.75 mg/kg daily (maximum dose, 40 mg/d) or deflazacort at 0.9 mg/kg daily (maximum dose, 39 mg/d), a derivative of prednisolone (not available in the United States), as a single morning dose is recommended for DMD patients older than 5 years, which may prolong independent walking from a few months to 2 years. (2)(3)(16)(17). Based on some research evidence, treatment with angiotensin-converting enzyme inhibitors, b-blockers, and diuretics has been reported to be beneficial in DMD patients with cardiac abnormalities. (2)(3)(5)(18). Based on expert opinion, children with muscle weakness and increased serum creatine kinase levels may be associated with either genetic or acquired muscle disorders (Tables 1 and 3).

    Skeletal muscle channelopathies are rare heterogeneous diseases with marked genotypic and phenotypic variability. Despite advances in understanding of the molecular pathology of these disorders, the diverse phenotypic manifestations remain a challenge in diagnosis and therapeutics. These disorders can cause lifetime disability and affect quality of life. There is no treatment of these disorders approved by the US Food and Drug Administration at this time. Recognition and treatment of symptoms might reduce morbidity and improve quality of life.

    Full Text Available Filariasis affecting animals can rarely cause infections in human beings through the accidental bite of potential vectors. The resulting infection in man, known as zoonotic filariasis occur worldwide. Human dirofilariasis, the most common zoonotic filariasis, is caused by the filarial worm belonging to the genus Dirofilaria. Dirofilarial worms, which are recognized as pathogenic in man can cause nodular lesions in the lung, subcutaneous tissue, peritoneal cavity or eyes. Oral dirofilariasis is extremely rare and only a few cases have been documented. We report an interesting case of dirofilariasis due to Dirofilaria repens involving buccal mucosa in a patient who presented with a facial swelling. The clinical features, diagnostic issues and treatment aspects are discussed. This paper stresses the importance of considering dirofilariasis as differential diagnosis for subcutaneous swelling of the face, especially in areas where it is endemic.

Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

    Full Text Available A amiloidose é uma doença complexa rara de difícil diagnóstico que ocorre devido à deposição de substância amilóide no meio extracelular. Ao ser diagnosticado na cavidade bucal, deve-se monitorar o paciente a fim de avaliar possíveis complicações sistêmicas da doença. Diante disso, o objetivo do presente estudo é relatar um caso de amiloidose oral em uma paciente do gênero feminino de 72 anos de idade. Baseado nos sinais clínicos observados, a hipótese diagnóstica foi de fibroma traumático. Após realização de biópsia e exame histopatológico, o diagnóstico foi de amiloidose oral, o que foi confirmado com a coloração do espécime com o reagente vermelho congo. Depósitos de amilóide foram encontrados no tecido conjuntivo, na avaliação através da luz polarizada, que apresentou birrefringência. Tal achado foi preocupante, já que a amiloidose geralmente acomete diversos tecidos levando a comprometimentos sistêmicos. Por essa razão a paciente foi encaminhada a procurar atendimento médico. No entanto, houve abandono do tratamento e a mesma veio a óbito 6 meses após o diagnóstico da doença. Lesões orais aparentemente simples podem revelar doenças raras e de difícil tratamento. O diagnóstico preciso e acompanhamentos médicos são fundamentais na sobrevida do paciente.

    2013-10-23

    Feline Chronic Gingivostomatitis Syndrome (FCGS) is a common disease in clinical practice. Among the therapeutic options available, long-acting corticosteroids are frequently used due to their anti-inflammatory and immunosuppressive properties. Although they may improve the clinical symptoms, they can lead to a progressive form of the disease that becomes refractory to treatment. Furthermore, their direct relationship with type II diabetes mellitus (DM) is well known. Consequently, these drugs are controversial and not recommended for routine management of FCGS. Recombinant feline interferon-omega (rFeIFN-ω) is an immunomodulatory compound. Recently, its daily oral administration has been shown to be successful in treating refractory cases of FCGS. This case study describes two clinical cases of type II DM complicated by FCGS. Both animals were calicivirus positive and they had been previously treated with long-acting corticosteroids, which may have been the major cause of DM. The two cats were treated with glargine insulin (Lantus, starting dose 1 IU/cat twice daily (BID)), achieving remission 10 and 18 weeks later respectively. Considering the difficulty with control of FCGS in these animals, an oral daily dose of rFeIFN-ω was started as an alternative to long-acting corticosteroids. In both cats oral clinical signs gradually improved and 60 days after the start of therapy the owners reported a significant relief of pain during mastication. According to the authors' knowledge, this is the first case report that describes the successful use of rFeIFN-ω in the management of FCGS in type II diabetic cats, in which long-acting corticosteroids are contraindicated.

    There are various surgical procedures for the reanimation of patients with long-standing facial paralysis. Temporalis muscle transfer is reliable for the reanimation of long-standing facial paralysis often employed when facial nerve reinnervation. It can be used as well for the immediate treatment of complete facial paralysis (more than 1 year) because temporalis muscle transposition does not interfere with neuronal regeneration. During the last few years the techniques employing the tendon of the temporalis muscle for the rehabilitation of the oral commissure gain increasing importance. The authors analyse the different options for reanimation after facial paralysis and report on a case of facial reanimation via temporalis muscle transfer.

    We investigated blood glucose (BG) and hormone response to aerobic high-intensity interval exercise (HIIE) and moderate continuous exercise (CON) matched for mean load and duration in type 1 diabetes mellitus (T1DM). Seven trained male subjects with T1DM performed a maximal incremental exercise test and HIIE and CON at 3 different mean intensities below (A) and above (B) the first lactate turn point and below the second lactate turn point (C) on a cycle ergometer. Subjects were adjusted to ultra-long-acting insulin Degludec (Tresiba/ Novo Nordisk, Denmark). Before exercise, standardized meals were administered, and short-acting insulin dose was reduced by 25% (A), 50% (B), and 75% (C) dependent on mean exercise intensity. During exercise, BG, adrenaline, noradrenaline, dopamine, cortisol, glucagon, and insulin-like growth factor-1, blood lactate, heart rate, and gas exchange variables were measured. For 24 h after exercise, interstitial glucose was measured by continuous glucose monitoring system. BG decrease during HIIE was significantly smaller for B (p = 0.024) and tended to be smaller for A and C compared to CON. No differences were found for post-exercise interstitial glucose, acute hormone response, and carbohydrate utilization between HIIE and CON for A, B, and C. In HIIE, blood lactate for A (p = 0.006) and B (p = 0.004) and respiratory exchange ratio for A (p = 0.003) and B (p = 0.003) were significantly higher compared to CON but not for C. Hypoglycemia did not occur during or after HIIE and CON when using ultra-long-acting insulin and applying our methodological approach for exercise prescription. HIIE led to a smaller BG decrease compared to CON, although both exercises modes were matched for mean load and duration, even despite markedly higher peak workloads applied in HIIE. Therefore, HIIE and CON could be safely performed in T1DM. ClinicalTrials.gov NCT02075567 http://www.clinicaltrials.gov/ct2/show/NCT02075567.

    The global health community has recognized that expanding the contraceptive method mix is a programmatic imperative since (1) one-third of unintended pregnancies are due to method failure or discontinuation, and (2) the addition of a new method to the existing mix tends to increase total contraceptive use. Since July 2011, CARE has been implementing the Supporting Access to Family Planning and Post-Abortion Care (SAFPAC) initiative to increase the availability, quality, and use of contraception, with a particular focus on highly effective and long-acting reversible methods-intrauterine devices (IUDs) and implants-in crisis-affected settings in Chad and the Democratic Republic of the Congo (DRC). This initiative supports government health systems at primary and referral levels to provide a wide range of contraceptive services to people affected by conflict and/or displacement. Before the initiative, long-acting reversible methods were either unknown or unavailable in the intervention areas. However, as soon as trained providers were in place, we noted a dramatic and sustained increase in new users of all contraceptive methods, especially implants, with total new clients reaching 82,855, or 32% of the estimated number of women of reproductive age in the respective catchment areas in both countries, at the end of the fourth year. Demand for implants was very strong in the first 6 months after provider training. During this time, implants consistently accounted for more than 50% of the method mix, reaching as high as 89% in Chad and 74% in DRC. To ensure that all clients were getting the contraceptive method of their choice, we conducted a series of discussions and sought feedback from different stakeholders in order to modify program strategies. Key program modifications included more focused communication in mass media, community, and interpersonal channels about the benefits of IUDs while reinforcing the wide range of methods available and refresher training for

    The goal of this study was to determine the impact of an oral hygiene education programme for caregivers on the oral health of institutionalised elderly and to examine the effect of disability and low muscle strength on programme outcomes. The subjects of this study were geriatric patients (n = 80) from a nursing home. Katz Index for activities of daily living, handgrip strength and mucosal-plaque score (MPS) was evaluated at baseline and 1 year after intervention. The intervention consisted of an educational programme and specific guidelines for caregivers (to perform oral hygiene for dependent elderly and to supervise the independent elderly during oral hygiene practices). Differences on MPS were evaluated using a paired-sample t-test. A stratified analysis was carried out to identify differences in response to the programme according to the Katz Index and handgrip strength of elderly. The MPS was significantly reduced (p = 0.001) at follow-up; however, a separate analysis showed that only the independent elderly (p = 0.002) and those with normal muscle strength (p = 0.006) showed a reduction in MPS during the follow-up examination. The oral hygiene education programme for caregivers resulted in a positive impact on oral hygiene of the independent and functional elderly. © 2013 The Gerodontology Society and John Wiley & Sons A/S.

    Full Text Available Glucagon like peptide-1 (GLP-1 receptor agonists such as exendin-4 have been widely used but their short half-life limits their therapeutic value. The recombinant protein, E2HSA, is a novel, long-acting GLP-1 receptor agonist generated by the fusion of exendin-4 with human serum albumin. In mouse pancreatic NIT-1 cells, E2HSA activated GLP-1 receptor with similar efficacy as exendin-4. After single-dose administration in ICR mice, E2HSA showed prolonged glucose lowering effects which lasted up to four days and extended inhibition on gastric emptying for at least 72 hours. Chronic E2HSA treatment in db/db mice significantly improved glucose tolerance, reduced elevated nonfasting and fasting plasma glucose levels, and also decreased HbA1c levels. E2HSA also increased insulin secretion and decreased body weight and appetite. Furthermore, immunofluorescence analysis showed that E2HSA increased β-cell area, improved islet morphology, and reduced β-cell apoptosis. In accordance with the promotion of β-cell function and survival, E2HSA upregulated genes such as Irs2, Pdx-1, Nkx6.1, and MafA and downregulated the expression levels of FoxO1 and proapoptotic Bcl-2 family proteins. In conclusion, with prolonged glucose lowering effects and promoting β-cell function and survival, the fusion protein, E2HSA, is a promising new therapeutic for once weekly treatment of type 2 diabetes.

    There are several new treatment options for patients whose asthma remains uncontrolled on free-dose and fixed-dose combinations of inhaled corticosteroids plus long-acting β2-agonists (ICS+LABA). In order to evaluate the likely impact of these treatments, we assessed the effect of uncontrolled asthma on healthcare and patient burden within the UK among adult patients treated with ICS+LABA. Data obtained from 2010-2011 UK National Health and Wellness Surveys identified 701 patients treated with ICS+LABA. Patients with not well-controlled asthma (Asthma Control Test™ score lower mental and physical health-related quality of life (P quality of life (both mentally and physically), impaired productivity and other health problems. The calculated direct and indirect costs per person with poorly controlled asthma were about double that for someone whose asthma was under control. The authors conclude that better treatment and management is needed to reduce costs and address the unmet medical need for people with persistent uncontrolled asthma.

    Full Text Available A new analog of EPO was designed by fusing one and two CTPs to the N-terminal and C-terminal ends of EPO (EPO-(CTP3, respectively. This analog was expressed and secreted efficiently in CHO cells. The in vitro test shows that the activity of EPO-(CTP3 in TFI-1 cell proliferation assay is similar to that of EPO-WT and commercial rHEPO. However, in vivo studies indicated that treatment once a week with EPO-(CTP3 (15 μg/kg dramatically increased (~8 folds haematocrit as it was compared to rHuEPO. Moreover, it was found that EPO-(CTP3 is more effective than rHuEPO and Aranesp in increasing reticulocyte number in mice blood. The detected circulatory half-lives of rHuEPO, Aranesp, and EPO-(CTP3 following IV injection of 20 IU were 4.4, 10.8, and 13.1 h, respectively. These data established the rational for using this chimera as a long-acting EPO analog in clinics. The therapeutic efficacy of EPO-CTP analog needs to be established in higher animals and in human clinical trials.

    To investigate whether the occurrence of nocturnal asymptomatic hypoglycemia may be predicted based on fasting glucose levels and post-breakfast glucose fluctuations. The study subjects comprised type 1 diabetic patients who underwent CGM assessments and received basal-bolus insulin therapy with long-acting insulin. The subjects were evaluated for I) fasting glucose levels and II) the range of post-breakfast glucose elevation (from fasting glucose levels to postprandial 1- and 2-hour glucose levels). The patients were divided into those with asymptomatic hypoglycemia during nighttime and those without for comparison. Optimal cut-off values were also determined for relevant parameters that could predict nighttime hypoglycemia by using ROC analysis. 64 patients (mean HbA1c 8.7 ± 1.8%) were available for analysis. Nocturnal asymptomatic hypoglycemia occurred in 23 patients (35.9%). Fasting glucose levels (I) were significantly lower in those with hypoglycemia than those without (118 ± 35 mg/dL vs. 179 ± 65 mg/dL; P fasting glucose level 54 mg/dL (0.65/0.61/0.71, P = 0.006), 2-h postprandial elevation > 78 mg/dL (0.65/0.73/0.71, P = 0.005). Nocturnal asymptomatic hypoglycemia was associated with increases in post-breakfast glucose levels in type 1 diabetes. Study findings also suggest that fasting glucose levels and the range of post-breakfast glucose elevation could help predict the occurrence of nocturnal asymptomatic hypoglycemia.

  11. Darbepoetin alpha, a long-acting erythropoeitin derivate, does not alter LPS evoked myocardial depression and gene expression of Bax, Bcl-Xs, Bcl-XL, Bcl-2, and TNF-alpha.

    Darbepoetin alpha (DA), a long-acting erythropoietin derivative stimulating erythropoiesis, can, by antiapoptotic effects, mitigate myocardial I/R injury. We tested the hypothesis that DA treatment improves left ventricular function (LV) in LPS evoked cardiomyopathy and alters gene expression of apoptosis-regulating proteins (Bcl-XL, Bcl-2, Bax, and Bcl-Xs) and TNF-alpha. In a prospective, controlled, randomized study in Lewis rats (n = 56; 8 groups), myocardial depression was evoked by LPS administration (serotype O127:B8; 10 mg/kg, i.p.). Darbepoetin alpha or vehicle was injected either 24 h before (pretreatment) or 2 h after LPS injection (treatment). Hearts were isolated 8 h after LPS injection, perfused (Krebs-Henseleit solution) in a Langendorff apparatus, and LV developed pressure and its derivatives were measured. For gene expression analysis, real-time polymerase chain reaction of LV specimen was performed. LPS decreased LV developed pressure (-64.6 +/- 7.9 mmHg) and its derivates by more than 60% in comparison to vehicle (P Xs, Bax, and TNF-alpha, but this was not altered by DA pretreatment. Furthermore, there was no effect on Bcl-Xl and Bcl-2 expression by DA alone. Whereas proapoptotic genes of the myocardium are up-regulated in LPS-induced cardiomyopathy, neither DA pretreatment nor treatment has significant effects on LV function or gene expression. This may suggest cardiac resistance to darbepoetin in LPS-mediated sepsis.

    To determine (1) how electromyographic activities of the genioglossus and geniohyoid muscles can be differentiated, and (2) whether changes in breathing modes and body positions have effects on the genioglossus and geniohyoid muscle activities. Ten normal subjects participated in the study. Electromyographic activities of both the genioglossus and geniohyoid muscles were recorded during nasal and oral breathing, while the subject was in the upright and supine positions. The electromyographic activities of the genioglossus and geniohyoid muscles were compared during jaw opening, swallowing, mandibular advancement, and tongue protrusion. The geniohyoid muscle showed greater electromyographic activity than the genioglossus muscle during maximal jaw opening. In addition, the geniohyoid muscle showed a shorter (P breathing modes and body positions, while there were no significant differences in the geniohyoid muscle activity. Electromyographic activities from the genioglossus and geniohyoid muscles are successfully differentiated. In addition, it appears that changes in the breathing mode and body position significantly affect the genioglossus muscle activity, but do not affect the geniohyoid muscle activity.

    Hypophosphatemia can lead to muscle weakness and respiratory and heart failure, but the mechanism is unknown. To address this question, we noninvasively assessed rates of muscle ATP synthesis in hypophosphatemic mice by using in vivo saturation transfer [(31)P]-magnetic resonance spectroscopy....... By using this approach, we found that basal and insulin-stimulated rates of muscle ATP synthetic flux (VATP) and plasma inorganic phosphate (Pi) were reduced by 50% in mice with diet-induced hypophosphatemia as well as in NaPi2a knockout mice (NaPi2a(-/-)) compared with their wild-type littermate controls...... hypophosphatemia as a result of a mutation in SLC34A3 who had a 50% reduction in both serum Pi content and muscle VATP After oral Pi repletion and normalization of serum Pi levels, muscle VATP completely normalized in the patient. Taken together, these data support the hypothesis that decreased muscle ATP...

    Marked ligamentous hyperlaxity and muscle weakness/wasting associated with awkward gait are the main deficits confused with the diagnosis of myopathy. Seven children (6 boys and 1 girl with an average age of 8 years) were referred to our department because of diverse forms of skeletal abnormalities. No definitive diagnosis was made, and all underwent a series of sophisticated investigations in other institutes in favor of myopathy. We applied our methodology through the clinical and radiographic phenotypes followed by targeted genotypic confirmation. Three children (2 boys and 1 girl) were compatible with the diagnosis of progressive pseudorheumatoid chondrodysplasia. The genetic mutation was correlated with the WISP 3 gene actively expressed by articular chondrocytes and located on chromosome 6. Klinefelter syndrome was the diagnosis in 2 boys. Karyotyping confirmed 47,XXY (aneuploidy of Klinefelter syndrome). And 2 boys were finally diagnosed with Morquio syndrome (MPS type IV A) as both showed missense mutations in the N-acetylgalactosamine-sulfate sulfatase gene. Misdiagnosis can lead to the initiation of a long list of sophisticated investigations. PMID:28210640

  17. Reconditioning aging muscles.

    1978-06-01

    Weakness or stiffness of key posture muscles can cause much of the disability seen in elderly patients. Too much tension and too little exercise greatly increase the natural loss of muscular fitness with age. A systematic program of exercise, stressing relaxation and stretching of tight muscles and strenghthening of weak muscles, can improve physical fitness. The program must be tailored to the patient, starting with relaxation and gentle limbering exercises and proceeding ultimately to vigorous muscle-stretching exercises. Muscle aches and pain from tension and muscle imbalance are to be expected. Relaxation relieves tension pain, and strengthening weak muscles and stretching tight muscles will correct muscle imbalance. To prevent acute muscle spasm, the patient should avoid excessive exertion and increase exercise intensity gradually.

    Full Text Available Abstract Background This post hoc analysis (trial registration: ClinicalTrials.gov NCT00590577 assessed onset of efficacy and tolerability of acute treatment with once-monthly paliperidone palmitate (PP, a long-acting atypical antipsychotic initiated by day 1 and day 8 injections, in a markedly to severely ill schizophrenia population. Methods Subjects entering the 13-week, double-blind trial were randomized to PP (39, 156, or 234 mg [25, 100, and 150 mg eq of paliperidone, respectively] or placebo. This subgroup analysis included those with a baseline Clinical Global Impressions-Severity (CGI-S score indicating marked to severe illness. PP subjects received a 234-mg day 1 injection (deltoid, followed by their assigned dose on day 8 and monthly thereafter (deltoid or gluteal. Thus, data for PP groups were pooled for days 4 and 8. Measures included Positive and Negative Syndrome Scale (PANSS, CGI-S, Personal and Social Performance (PSP, and adverse events (AEs. Analysis of covariance (ANCOVA and last-observation-carried-forward (LOCF methodologies, without multiplicity adjustments, were used to assess changes in continuous measures. Onset of efficacy was defined as the first time point a treatment group showed significant PANSS improvement (assessed days 4, 8, 22, 36, 64, and 92 versus placebo, which was maintained through end point. Results A total of 312 subjects met inclusion criterion for this subgroup analysis. After the day 1 injection, mean PANSS total scores improved significantly with PP (all received 234 mg versus placebo at day 4 (P = 0.012 and day 8 (P = 0.007. After the day 8 injection, a significant PANSS improvement persisted at all subsequent time points in the 234-mg group versus placebo (P P P P Conclusions In this markedly to severely ill population, acute treatment with 234 mg PP improved psychotic symptoms compared with placebo by day 4. After subsequent injections, observed improvements are suggestive of a dose

    The ability of a chronic treatment with indacaterol, a new ultra-long-acting β2 -adrenoceptor agonist, to reverse cardiac remodelling and its effects in combination with metoprolol, a selective β1 -adrenoceptor antagonist, were investigated on myocardial infarction in a rat model of heart failure (HF). We investigated the effects of indacaterol and metoprolol, administered alone or in combination, on myocardial histology, β-adrenoceptor-mediated pathways, markers of remodelling and haemodynamic parameters in a rat model of HF. Five groups of rats were assessed: sham-operated rats; HF rats; HF + indacaterol 0.3 mg·kg(-1) ·day(-1) ; HF + metoprolol 100 mg·kg(-1) ·day(-1) ; HF + metoprolol + indacaterol. All pharmacological treatments continued for 15 weeks. Treatment with either indacaterol or metoprolol significantly reduced the infarct size in HF rats. However, the combination of indacaterol and metoprolol reduced the infarct size even further, reduced both BP and heart rate, reversed the decrease in ejection fraction, normalized left ventricular systolic and diastolic internal diameters, normalized the decreased β1 adrenoceptor mRNA expression as well as cardiac cAMP levels and reduced cardiac GPCR kinase 2 expression, compared with the untreated HF group. The results of our study demonstrated an additive interaction between indacaterol and metoprolol in normalizing and reversing cardiac remodelling in our experimental model of HF. The translation of these findings to clinical practice might be of interest, as this combination of drugs could be safer and more effective in patients suffering from HF and COPD. © 2015 The British Pharmacological Society.

    Granulocyte colony-stimulating factors (G-CSF) are commonly used in clinical practice to prevent febrile neutropenia (FN). US and EU prescribing information and treatment guidelines from the NCCN, ASCO, and EORTC specify that pegfilgrastim, a long-acting (LA) G-CSF, should be administered at least 24 h after myelosuppressive chemotherapy. Nevertheless, many patients receive LA G-CSFs on the same day as chemotherapy. This systematic literature review evaluated the relative merits of same-day versus next-day dosing of LA G-CSFs. A broad Ovid MEDLINE® and Embase® literature search was conducted that examined all publications indexed before May 9, 2016 that compared same-day versus next-day LA G-CSF administration. A congress abstract literature search included congresses from January 1, 2011 to April 6, 2016. The parameters for this review were prospectively delineated in a research protocol and adhered to the PRISMA Guidelines. The first part of the systematic literature search identified 1736 publications. After elimination of duplicates, title/abstract screening was conducted on 1440 records, and full text review was conducted on 449 publications. Eleven publications met all criteria and are included in this systematic review; of these, four included data from randomized or single arm prospective studies, and seven were retrospective studies. In most studies included in this review and across a variety of tumor types, administration of pegfilgrastim at least 24 h after myelosuppressive chemotherapy resulted in improved patient outcomes. Data from multiple publications support administration of pegfilgrastim at least 1 day after chemotherapy.

  1. Adherence to Long-Acting Bronchodilators After Discharge for COPD: How Much of the Geographic Variation is Attributable to the Hospital of Discharge and How Much to the Primary Care Providers?

    In moderate-severe chronic obstructive pulmonary disease (COPD), long-acting bronchodilators (LBs) are recommended to improve the quality of life. The aims of this study were to measure adherence to LBs after discharge for COPD, identify determinants of adherence, and compare amounts of variation attributable to hospitals of discharge and primary care providers, i.e. local health districts (LHDs) and general practitioners (GPs). This cohort study was based on the Lazio region population, Italy. Patients discharged in 2007-2011 for COPD were followed up for 2 years. Adherence was defined as a medication possession ratio >80%. Cross-classified models were performed to analyse variation. Variances were expressed as median odds ratios (MORs). An MOR of 1.00 stands for no variation, a large MOR indicates considerable variation. We enrolled 13,178 patients. About 29% of patients were adherent to LBs. Adherence was higher for patients discharged from pneumology wards and for patients with GPs working in group practice. A relevant variation between LHDs (MOR = 1.21, p = 0.001) and GPs (MOR = 1.28, p = 0.035) was detected. When introducing the hospital of discharge in the model, the MOR related to LHDs decreased to 1.05 (p = 0.345), MOR related to GPs dropped to 1.22 (p = 0.086), whereas MOR associated with hospitals of discharge was 1.38 (p variation was observed. This heterogeneity raises equity concerns in access to optimal care. The reduction of variability among LHDs and GPs after entering the hospital level proved that differences we observe in primary care partially 'reflect' the clinical approach of hospitals of discharge.

  2. [Muscle cramps--differential diagnosis and therapy].

    Reichel, Gerhard

    2009-03-01

    Calf cramps are sudden, involuntary, painful contractions of part of or the entire calf muscle that are visible, persist for seconds to minutes and then spontaneously resolve. They can occur with no identifiable cause, and are then referred to as common calf cramps. They may also be symptoms associated with diseases of the peripheral and central nervous system and muscle diseases. They also occur in association with metabolic disorders. In such cases the cramps are more extensive, intense and persist for longer. Cramp-fasciculation-myalgia syndrome additionally involves paresthesias and other signs of hyperexcitability of peripheral nerves. The recommended treatment for patients with frequent calf cramps causing significant impairment of well-being is oral administration of quinidine and/or botulinum toxin treatment of the calf muscles. During pregnancy both products are contraindicated, while probatory administration of magnesium is indicated.

    Nitric oxide (NO) mediates activation of satellite precursor cells to enter the cell cycle. This provides new precursor cells for skeletal muscle growth and muscle repair from injury or disease. Targeting a new drug that specifically delivers NO to muscle has the potential to promote normal function and treat neuromuscular disease, and would also help to avoid side effects of NO from other treatment modalities. In this research, we examined the effectiveness of the NO donor, iosorbide dinitrate (ISDN), and a muscle relaxant, methocarbamol, in promoting satellite cell activation assayed by muscle cell DNA synthesis in normal adult mice. The work led to the development of guaifenesin dinitrate (GDN) as a new NO donor for delivering nitric oxide to muscle. The results revealed that there was a strong increase in muscle satellite cell activation and proliferation, demonstrated by a significant 38% rise in DNA synthesis after a single transdermal treatment with the new compound for 24 h. Western blot and immunohistochemistry analyses showed that the markers of satellite cell myogenesis, expression of myf5, myogenin, and follistatin, were increased after 24 h oral administration of the compound in adult mice. This research extends our understanding of the outcomes of NO-based treatments aimed at promoting muscle regeneration in normal tissue. The potential use of such treatment for conditions such as muscle atrophy in disuse and aging, and for the promotion of muscle tissue repair as required after injury or in neuromuscular diseases such as muscular dystrophy, is highlighted.

    The human body contains approximately 640 individual skeletal muscles. Despite the fact that all of these muscles are composed of striated muscle tissue, the biology of these muscles and their associated muscle stem cell populations are quite diverse. Skeletal muscles are affected differentially by various muscular dystrophies, such that certain genetic mutations specifically alter muscle function in only a subset of muscles. Additionally, defective muscle stem cells have been implicated in t...

  16. Muscle strain injuries.

    Science.gov (United States)

    Garrett, W E

    1996-01-01

    One of the most common injuries seen in the office of the practicing physician is the muscle strain. Until recently, little data were available on the basic science and clinical application of this basic science for the treatment and prevention of muscle strains. Studies in the last 10 years represent action taken on the direction of investigation into muscle strain injuries from the laboratory and clinical fronts. Findings from the laboratory indicate that certain muscles are susceptible to strain injury (muscles that cross multiple joints or have complex architecture). These muscles have a strain threshold for both passive and active injury. Strain injury is not the result of muscle contraction alone, rather, strains are the result of excessive stretch or stretch while the muscle is being activated. When the muscle tears, the damage is localized very near the muscle-tendon junction. After injury, the muscle is weaker and at risk for further injury. The force output of the muscle returns over the following days as the muscle undertakes a predictable progression toward tissue healing. Current imaging studies have been used clinically to document the site of injury to the muscle-tendon junction. The commonly injured muscles have been described and include the hamstring, the rectus femoris, gastrocnemius, and adductor longus muscles. Injuries inconsistent with involvement of a single muscle-tendon junction proved to be at tendinous origins rather than within the muscle belly. Important information has also been provided regarding injuries with poor prognosis, which are potentially repairable surgically, including injuries to the rectus femoris muscle, the hamstring origin, and the abdominal wall. Data important to the management of common muscle injuries have been published. The risks of reinjury have been documented. The early efficacy and potential for long-term risks of nonsteroidal antiinflammatory agents have been shown. New data can also be applied to the field

    2009-01-01

    There are no effective and convenient therapeutic management on refractory cardiac arrest induced by long-acting local anesthetic toxicity. Although there are no any randomly controlled trials showing the effectiveness of lipid emulsion for anesthetic toxicity resuscitation in human beings mostly because of ethic issues, lipid emulsion has been proved to be effective in animal models undergoing local anesthetic toxicity. This novel approach to treating potentially fatal cardiac toxicity is still at an early stage but holds promise for clinical application. Literatures suggest that lipid emulsion resuscitation should be as a reserve step because of lacking clinical investigative evidence. However, more and more case reports indicate that lipid emulsion should be used earlier in order to avoid local anesthetic toxicity deteriorated. Further work is required to explore mechanism of lipid emulsion on resuscitation of local anesthetic toxicity and optimize the treatment regimens with respect to efficacy and safety of lipid rescue.%长效局麻药(local anesthetic,LA)中毒所致顽固性心跳骤停,目前临床尚无有效便捷的治疗方法.动物研究发现静脉注射脂肪乳(lipid emulsion,LE)可治疗布比卡因所致心跳骤停.因尚缺乏有力的临床研究证据支持,文献建议LE作为LA心脏毒性标准心肺复苏的备用措施.但多例个案报道提示,一旦出现LA毒性症状,应尽早使用LE救治,以避免LA毒性综合征的发展.未来的研究方向应致力于探索LE救治有效性的确切机制,寻求临床适用的最佳使用方法,确立治疗标准.

  10. Zidovudine-induced mitochondrial myopathy is associated with muscle carnitine deficiency and lipid storage.

    Dalakas, M C; Leon-Monzon, M E; Bernardini, I; Gahl, W A; Jay, C A

    1994-04-01

    The use of zidovudine (AZT) for the treatment of acquired immunodeficiency syndrome (AIDS) induces a DNA-depleting mitochondrial myopathy, which is histologically characterized by the presence of muscle fibers with "ragged-red"-like features, red-rimmed or empty cracks, granular degeneration, and rods (AZT fibers). Because dysfunctioning muscle mitochondria may lead to defects of beta-oxidation of fatty acids, we examined the degree of neutral fat accumulation and muscle carnitine levels in the muscle biopsy specimens from 21 patients with AZT-induced myopathic symptoms of varying severity. Six patients with no AZT fibers had normal endomyofibrillar lipid deposits and muscle carnitine levels; 7 patients with fewer than 5 AZT fibers per field had a mild (+) to moderate (++) increase in lipid droplets, and reduced muscle carnitine levels (3 patients); and 8 patients with more than 5 AZT fibers had severe muscle changes, a ++ to marked ( ) increase in lipid droplets, and reduced muscle carnitine levels (6 patients). Serial sections showed lipid globules often within "cracks" or vacuoles of the abnormal muscle fibers. We conclude that the muscle mitochondrial impairment caused by AZT results in (1) accumulation of lipid within the muscle fibers owing to poor utilization of long-chain fatty acids, (2) reduction of muscle carnitine levels probably due to decreased carnitine uptake by the muscle, and (3) depletion of energy stores within the muscle fibers. The findings may have potential therapeutic implications in the treatment of AZT-induced myopathic symptoms using oral carnitine supplementation.

    Many oral diseases and conditions, including dental caries (cavities) and malocclusions, have their origins early in life. Prudent anticipatory guidance by the medical and dental professions can help prevent many of the more common oral health problems. This article provides information on the rationale for early dental examination and instructions for pediatric and family practitioners in scheduling and conducting an early oral intervention appointment. In addition, feeding practices, non-nutritive sucking, mouth breathing, and bruxing are discussed, including their effects on orofacial growth and development.

    2015-11-01

    Oral steroid contraception is a popular method of family planning worldwide. Over the past several decades, this method of contraception has changed significantly by decreasing the estrogen dose, changing the progestin component, and reducing the hormone free interval. Despite the popularity of oral steroid contraception, there has been much criticism regarding the associated risks of venous thromboembolism and stroke. Despite these established, yet uncommon risks, oral steroid contraception has many important health benefits. This review highlights the available formulations of oral contraceptives along with their evidence-based associated risks and benefits. Highlights regarding future directions for development of novel oral contraceptives are also addressed.

  13. Oral vs. pharyngeal dysphagia: surface electromyography randomized study.

    Vaiman, Michael; Nahlieli, Oded

    2009-05-21

    A clear differential diagnosis between oral and pharyngeal dysphagia remains an unsolved problem. Disorders of the oral cavity are frequently overlooked when dysphagia/odybophagia complaints are assessed. Surface electromyographic (sEMG) studies were performed on randomly assigned patients with oral and pharyngeal pathology to evaluate their dysphagia complaints for the sake of differential diagnosis. Parameters evaluated during swallowing for patients after dental surgery (1: n = 62), oral infections (2: n = 49), acute tonsillitis (3: n = 66) and healthy controls (4: n = 50) included timing and amplitude of sEMG activity of masseter, infrahyoid and submental muscles. The duration of swallows and drinking periods was significantly increased in dental patients and was normal in patients with tonsillitis. The electric activity of masseter was significantly lower in Groups 1 and 2 in comparison with the patients with tonsillitis and controls. The submental and infrahyoid activity was normal in dental patients but infrahyoid activity in patients with tonsillitis was high. Dysphagia following dental surgery or oral infections does not affect pharynx and submental muscles and has clear sEMG signs: increased duration of a single swallow, longer drinking time, low activity of the masseter, and normal range of submental activity. Patients with tonsillitis present hyperactivity of infrahyoid muscles. These data could be used for evaluation of symptoms when differential dental/ENT diagnosis is needed.

    Full Text Available Abstract Background A clear differential diagnosis between oral and pharyngeal dysphagia remains an unsolved problem. Disorders of the oral cavity are frequently overlooked when dysphagia/odybophagia complaints are assessed. Surface electromyographic (sEMG studies were performed on randomly assigned patients with oral and pharyngeal pathology to evaluate their dysphagia complaints for the sake of differential diagnosis. Methods Parameters evaluated during swallowing for patients after dental surgery (1: n = 62, oral infections (2: n = 49, acute tonsillitis (3: n = 66 and healthy controls (4: n = 50 included timing and amplitude of sEMG activity of masseter, infrahyoid and submental muscles. Results The duration of swallows and drinking periods was significantly increased in dental patients and was normal in patients with tonsillitis. The electric activity of masseter was significantly lower in Groups 1 and 2 in comparison with the patients with tonsillitis and controls. The submental and infrahyoid activity was normal in dental patients but infrahyoid activity in patients with tonsillitis was high. Conclusion Dysphagia following dental surgery or oral infections does not affect pharynx and submental muscles and has clear sEMG signs: increased duration of a single swallow, longer drinking time, low activity of the masseter, and normal range of submental activity. Patients with tonsillitis present hyperactivity of infrahyoid muscles. These data could be used for evaluation of symptoms when differential dental/ENT diagnosis is needed.

    Full Text Available Many oral lesions may need to be diagnosed by removing a sample of tissue from the oral cavity. Biopsy is widely used in the medical field, but the practice is not quite widespread in dental practice. As oral pathologists, we have found many artifacts in the tissue specimen because of poor biopsy technique or handling, which has led to diagnostic pitfalls and misery to both the patient and the clinician. This article aims at alerting the clinicians about the clinical faults arising preoperatively, intraoperatively and postoperatively while dealing with oral biopsy that may affect the histological assessment of the tissue and, therefore, the diagnosis. It also reviews the different techniques, precautions and special considerations necessary for specific lesions.

    Optical characterization and internal structure of biological tissues is highly important for biomedical optics. In particular for optical clearing processes, such information is of vital importance to understand the mechanisms involved through the variation of the refractive indices of tissue components. The skeletal muscle presents a fibrous structure with an internal arrangement of muscle fiber cords surrounded by interstitial fluid that is responsible for strong light scattering. To determine the refractive index of muscle components we have used a simple method of measuring tissue mass and refractive index during dehydration. After performing measurements for natural and ten dehydration states of the muscle samples, we have determined the dependence between the refractive index of the muscle and its water content. Also, we have joined our measurements with some values reported in literature to perform some calculations that have permitted to determine the refractive index of the dried muscle fibers and their corresponding volume percentage inside the natural muscle.

    Microstomia reconstruction due to the presence a blunted oral commissure is a challenging task because it requires the restoration of intricately balanced distinct layers of tissues: the oral mucosa, the orbicular muscle, the vermilion border, and the perioral skin. The reliability of commissural reconstruction depends on 2 factors: the first one is breaking the contraction vectors causing blunting of the commissure and the second one is restoring the integrity of the o
