    Currently, the Category (CAT) II regimen is recommended for patients who have failed the CAT I regimen. We have determined before that prevalence of multidrug-resistant tuberculosis (MDR TB) is relatively high among these patients. On the other hand, the retreatment success rate with CAT II in CAT I treatment failures and defaults is nearly 50%. Therefore, we tried to find another strategy with a higher success rate. From January 2004 to November 2007, 105 patients with pulmonary TB, who failed a prior CAT I regimen or with more than one course of irregular anti-TB treatment, were included in this study, whereas five cases with nontuberculous mycobacteria were excluded. Drug susceptibility testing (DST), for first line anti-TB drugs, and polymerase chain reaction were performed. By the time of availability of DST that took 3 to 4 months, a pilot protocol consisted of isoniazid, rifampin, ethambutol, ofloxacin, cycloserine, and amikacin was started. Then therapeutic regimen was adjusted based on four categories of DST pattern: sensitive, non-MDR pattern, MDR pattern, and culture-negative. Sensitive patients received the standard CAT I regimen, non-MDR patients an individualized regimen based on DST, MDR patients a standard second-line regimen, and culture-negatives a standard CAT I plus a 6-month injectable agent. Treatment outcomes were categorized and analyzed. Forty-eight patients with prior CAT I treatment failure and 52 with more than one irregular treatment courses were included in the analysis. Six percent of subjects had confirmed HIV infection. Seventy-two percent of subjects were assigned to a good outcome and 28% were assigned to a poor outcome group. Seventeen percent were culture-negative. Regarding DST pattern, 13% isolated strains were completely sensitive to first-line drugs. 53% strains were MDR, 10% monodrug-resistant, and 7% polydrug-resistant. There was no significant association between DST pattern and outcome (P = 0.13). The irregular regimen

    Background: Treatment of multidrug-resistant tuberculosis (MDR-TB) in the Programmatic Management of Drug-resistant TB program involves a standard regimen with a 6-month intensive phase and an 18-month continuation phase. However, the local drug resistance patterns in high MDR regions such as Mumbai may not be adequately reflected in the design of the regimen for that particular area. Setting: The study was carried out at a private Tertiary Level Hospital in Mumbai in a mycobacteriology laboratory equipped to perform the second-line drug susceptibility testing (DST). Objective: We attempted to analyze the impact of prescribing the standardized Category IV regimen to all patients receiving a DST at our mycobacteriology laboratory. Materials and Methods: All samples confirmed to be MDR-TB and tested for the second-line drugs at Hinduja Hospital's Mycobacteriology Laboratory in the year 2012 were analyzed. Results: A total of 1539 samples were analyzed. Of these, 464 (30.14%) were MDR-TB, 867 (56.33%) were MDR with fluoroquinolone resistance, and 198 (12.8%) were extensively drug-resistant TB. The average number of susceptible drugs per sample was 3.07 ± 1.29 (assuming 100% cycloserine susceptibility). Taking 4 effective drugs to be the cut or an effective regimen, the number of patients receiving 4 or more effective drugs from the standardized directly observed treatment, short-course plus regimen would be 516 (33.5%) while 66.5% of cases would receive 3 or less effective drugs. Conclusion: Our study shows that a high proportion of patients will have resistance to a number of the first- and second-line drugs. Local epidemiology must be factored in to avoid amplification of resistance. PMID:27185987

    OBJECTIVE Category II fetal heart rate (FHR) tracings are considered indeterminate, thus improved risk stratification of category II FHR tracings is needed. We estimated whether the presence of meconium increased the risk of adverse neonatal outcomes. STUDY DESIGN This study was conducted within a prospective cohort of 5000 women with singleton pregnancies admitted in labor at term. Pregnancies with category II FHR in the 60 minutes prior to delivery were included. FHR data were extracted by trained nurses blinded to clinical outcome. The exposure was presence of meconium. The primary outcome was a composite neonatal morbidity defined as ≥1 of the following: neonatal death, neurologic morbidity, respiratory morbidity, hypotension requiring treatment, and sepsis. Secondary outcomes were nursery admission, cord pH, 5-minute Apgar score, and components of the composite. Logistic regression was used to adjust for confounders. RESULTS Of the 3,257 women with category II FHR tracings, 693 (21.3%) had meconium and 2,564 (78.7%) did not. Meconium was associated with higher risk of the composite morbidity (aOR 2.49, 95% CI 1.78-3.48) and increased risks of the secondary outcomes. The associations remained significant when infants with meconium aspiration syndrome were excluded. Thick meconium was significantly associated with the composite morbidity. CONCLUSIONS The presence of meconium is associated with an increased risk of neonatal morbidity in women with category II FHR pattern. This clinical factor may assist clinicians in managing category II FHR patterns in labor. PMID:24949543

    Background The aim of this study was to compare the safety and immunogenicity between purified vero cell rabies vaccine (PVRV) and purified chick embryo cell vaccine (PCECV) in patients with WHO category II animal exposure, especially in different age groups. Methodology/Principal Findings In one-year clinical observation after vaccination with PVRV or PCECV under Zagreb (2-1-1) or Essen (1-1-1-1-1) regimens, information collection for the demographic and adverse events (AEs) and rabies virus laboratory examination of neutralizing antibody (RVNA) titers were performed for all patients with WHO category II animal exposure in Wuhan city. The results showed no significant differences of safety and immunogenicity between PVRV and PCECV both in Zagreb and Essen regimens. However, when compared with other age groups, most systemic AEs (36/61) occurred in <5-year-old patients, and <5-year-old patients have significant lower RVNA titer and seroconversion rate (RVNA ≥0.5 IU/ml) at day 7 both in Zagreb and Essen regimens or PVRV and PCECV groups. Conclusions Our data showed that vaccination with PVRV is as safe and immunogenic as PCECV in patients of all age groups, but might be more popular for clinical use. When performing a vaccination with rabies vaccine in young children, the most optimal vaccine regimen should be selected. PMID:25522244

    Objective To evaluate whether a subcategory system for category II tracings can improve team communication and perinatal outcomes. Study Design We collected data prospectively for 15 months, first using the NICHD system, followed by the ABC system, which divides category II tracings into subcategories A, B, and C, each representing increased risk for metabolic acidemia. We surveyed providers about communication effectiveness and agreement on tracing interpretation for each system. In cases where the communication system was used to alert an off-site physician about a category II tracing, we compared arrival to L&D and NICU admissions. Results The ABC system was preferred (69%, n = 152) and considered a more effective tool for communicating concerning fetal status (80% vs. 43%, p < 0.01). Participants also reported greater agreement on tracing interpretation (79% for ABC vs. 64% for NICHD, p = 0.046). When an off-site physician was contacted about a category II tracing (n = 95), they were more likely to arrive to L&D (44% vs. 20%, p < 0.01) and have fewer NICU admissions (0% vs. 6%, p < 0.01) with the ABC system. Conclusion The ABC system resulted in improved team communication, increased physician response, and decreased NICU admissions. Using standardized communication may offer a useful strategy for identifying and expediting care. PMID:26871906

    The present study assessed whether placentas in women delivered by cesarean for category II fetal heart tracings (FHT) exhibit a higher incidence of acute inflammation than those of women delivered by cesarean for labor arrest. This case control study included singleton pregnancies ≥36 weeks of gestation delivered by cesarean for an FHT indication (cases) or because of labor arrest (controls) 2005-2009 at Prentice Women's Hospital. Exclusions were maternal diabetes, hypertension, known thrombophilia, connective tissue disorders, clinical evidence of chorioamnionitis, placental abruption, fetal anomalies, stillbirth, or an infant with a birth weight less than the 10th percentile. Women were included in the case group if the indication for cesarean delivery was based on the FHT and review of the FHT determined that they were designated as category II prior to delivery. A perinatal pathologist, unaware of indications for delivery, assessed placental inflammation in maternal and fetal compartments. Stage and grade of acute inflammation, from none to severe (scored 0-3), in the membranes, chorionic plate, chorionic vessels, and umbilical cord were assessed, and overall maternal and fetal inflammatory stages were assigned. Findings indicative of chronic inflammation were also noted. Other than lower umbilical artery cord gases in women with category II FHT, cases (n  =  51) and controls (n  =  27) had similar baseline characteristics and newborn outcomes, as well as similar placental pathologic findings. In uncomplicated patients, the presence or extent of placental inflammation does not appear to differ between women delivered for category II FHT and labor arrest. PMID:22671990

  3. A cooperative clinical study of methadyl acetate. II. Friday-only regimen.

    1980-08-01

    We conducted an open clinical trial of the feasibility of maintaining heroin addicts by administering methadone hydrochloride on Monday through Thursday, methadyl acetate on Friday, and no drug at all on Saturday or Sunday. Sixty-five patients from four participating clinics were randomly assigned to this schedule and another 71 to a daily methadone comparison group. The patient sample consisted of heroin addicts previously stabilized on a maintenance regimen of methadone. The starting dose of methadyl acetate was identical to the previously established dose of methadone but was flexible within limites thereafter. A greater number of patients in the methadyl acetate group failed to complete the full 40 weeks of the study, particularly because they claimed the medication was not holding. Although this particular use of methadyl acetate on Friday to provide a drug-free weekend does not appear to be widely applicable clinically, the fact that at least some patients in the methadyl acetate group tolerated the schedule with little or no illicit drug use or obvious discomfort suggests that the strategy is viable and should not be discarded.

    We investigated which item subsets of the Vineland-II can discriminate low-functioning preschoolers with ASD from matched peers with other neurodevelopmental disorders, using a regression analysis derived from a normative sample to account for cognitive and linguistic competencies. At variance with the typical profile, a pattern with Communication more impaired than Socialization was observed. The source of the frequently reported Socialization delay in ASD appears to be in Playing and Imitating skills only, not in other social adaptive behavior skills. The combination of item subsets Playing, Following instructions, Beginning to talk, and Speech skills provided the best discrimination between the two clinical groups. Evaluation of the Vineland-II score on item content categories is a useful procedure for a more efficient clinical description. PMID:26210516

    The MODEL1 trial is the first model-driven phase I/II dose-escalation study of densified docetaxel plus epirubicin administration in metastatic breast cancer patients, a regimen previously known to induce unacceptable life-threatening toxicities. The primary objective was to determine the maximum tolerated dose of this densified regimen. Study of the efficacy was a secondary objective. Her2-negative, hormone-resistant metastatic breast cancer patients were treated with escalating doses of docetaxel plus epirubicin every 2 weeks for six cycles with granulocyte colony stimulating factor support. A total of 16 patients were treated with total doses ranging from 85 to 110 mg of docetaxel plus epirubicin per cycle. Dose escalation was controlled by a non-hematological toxicity model. Dose densification was guided by a model of neutrophil kinetics, able to optimize docetaxel plus epirubicin dosing with respect to pre-defined acceptable levels of hematological toxicity while ensuring maximal efficacy. The densified treatment was safe since hematological toxicity was much lower compared to previous findings, and other adverse events were consistent with those observed with this regimen. The maximal tolerated dose was 100 mg given every 2 weeks. The response rate was 45 %; median progression-free survival was 10.4 months, whereas 54.6 months of median overall survival was achieved. The optimized docetaxel plus epirubicin dosing regimen led to fewer toxicities associated with higher efficacy as compared with standard or empirical densified dosing. This study suggests that model-driven dosage adjustment can lead to improved efficacy-toxicity balance in patients with cancer when several anticancer drugs are combined. PMID:27002506

    In oncology, vaccine-based immunotherapy often investigates regimens that demonstrate minimal toxicity overall and higher doses may not correlate with greater immune response. Rather than determining the maximum tolerated dose, the goal of the study becomes locating the optimal biological dose, which is defined as a safe dose demonstrating the greatest immunogenicity, based on some predefined measure of immune response. Incorporation of adjuvants, new or optimized peptide vaccines, and combining vaccines with immune modulators may enhance immune response, with the aim of improving clinical response. Innovative dose escalation strategies are needed to establish the safety and immunogenicity of new immunologic combinations. We describe the implementation of an adaptive design for identifying the optimal treatment strategy in a multi-site, FDA-approved, phase I/II trial of a novel vaccination approach using long-peptides plus TLR agonists for resected stage IIB-IV melanoma. Operating characteristics of the design are demonstrated under various possible true scenarios via simulation studies. Overall performance indicates that the design is a practical Phase I/II adaptive method for use with combined immunotherapy agents. The simulation results demonstrate the method's ability to effectively recommend optimal regimens in a high percentage of trials with manageable sample sizes. The numerical results presented in this work include the type of simulation information that aid review boards in understanding design performance, such as average sample size and frequency of early trial termination, which we hope will augment early-phase trial design in cancer immunotherapy.

    This study investigated the influence of day of gestation (DG) and feeding regimens (FR) on maternal and fetal visceral organ mass in Holstein × Gyr cows. Forty-four pregnant multiparous Holstein × Gyr cows with an average initial body weight of 480±10.1 kg and an average initial age of 5±0.5 yr were allocated to 1 of 2 FR: ad libitum (AL; n=20) or maintenance level (ML; n=24). Maintenance level was considered to be 1.15% of body weight (dry matter basis) and met 100% of the energy requirements; AL provided 190% of the total net energy requirements. Cows were individually fed a corn silage and concentrate-based diet composed of 93% roughage and 7% concentrate (dry matter basis) as a total mixed ration twice daily. Pregnant cows were slaughtered at 4 DG: 139 (n=11), 199 (n=11), 241 (n=11), and 268 (n=11) d, which was followed by necropsy. Mass of heart, liver, and gastrointestinal tract was heavier in AL- than in ML-fed cows. Mammary gland mass was heavier in AL- than in ML-fed cows, and the heaviest mass was observed at 268 d of gestation. Feeding regimen did not influence fetal body weight in this study. The majority of the visceral organ masses were similar in fetuses from cows fed AL or ML. These data indicate that maternal feed restriction does not affect the development of most fetal organs or fetal development; however, some maternal organs are affected by the FR provided. Moreover, the negative effect on mammary gland mass caused by ML feeding will probably not affect the subsequent lactation because the crude protein concentration in the mammary gland increased with ML feeding. However, we suggest that the AL diet in pregnant dry cows should be provided with caution because the amount of fat in the mammary gland increased at 268 d of gestation. PMID:25726105

  10. Categorial Compositionality II: Universal Constructions and a General Theory of (Quasi-)Systematicity in Human Cognition

    2011-01-01

    A complete theory of cognitive architecture (i.e., the basic processes and modes of composition that together constitute cognitive behaviour) must explain the systematicity property—why our cognitive capacities are organized into particular groups of capacities, rather than some other, arbitrary collection. The classical account supposes: (1) syntactically compositional representations; and (2) processes that are sensitive to—compatible with—their structure. Classical compositionality, however, does not explain why these two components must be compatible; they are only compatible by the ad hoc assumption (convention) of employing the same mode of (concatenative) compositionality (e.g., prefix/postfix, where a relation symbol is always prepended/appended to the symbols for the related entities). Architectures employing mixed modes do not support systematicity. Recently, we proposed an alternative explanation without ad hoc assumptions, using category theory. Here, we extend our explanation to domains that are quasi-systematic (e.g., aspects of most languages), where the domain includes some but not all possible combinations of constituents. The central category-theoretic construct is an adjunction involving pullbacks, where the primary focus is on the relationship between processes modelled as functors, rather than the representations. A functor is a structure-preserving map (or construction, for our purposes). An adjunction guarantees that the only pairings of functors are the systematic ones. Thus, (quasi-)systematicity is a necessary consequence of a categorial cognitive architecture whose basic processes are functors that participate in adjunctions. PMID:21857816

A functor is a structure-preserving map (or construction, for our purposes). An adjunction guarantees that the only pairings of functors are the systematic ones. Thus, (quasi-)systematicity is a necessary consequence of a categorial cognitive architecture whose basic processes are functors that participate in adjunctions. PMID:21857816

  12. Gerson regimen.

    The Gerson regimen, developed by Max Gerson in the 1930s, is promoted as an alternative cancer treatment. It involves consuming fresh, raw fruit and vegetable juices, eliminating salt from the diet, taking supplements such as potassium, vitamin B12, thyroid hormone, pancreatic enzymes, and detoxifying liver with coffee enemas to stimulate metabolism. Gerson therapy is based on the theory that cancer is caused by alteration of cell metabolism by toxic environmental substances and processed food, which changes its sodium and potassium content. It emphasizes increasing potassium intake and minimizing sodium consumption in an effort to correct the electrolyte imbalance, repair tissue, and detoxify the liver. The coffee enemas are believed to cause dilation of bile ducts and excretion of toxic breakdown products by the liver and through the colon wall. None of these theories has been substantiated by scientific research. Despite proponents' claims of recovery rates as high as 70% to 90%, case reviews by the National Cancer Institute (NCI) and the New York County Medical Society found no evidence of usefulness for the Gerson diet. An NCI-sponsored study of Gonzalez therapy, which is similar to the Gerson diet, showed that patients with inoperable pancreatic adenocarcinoma who underwent standard chemotherapy with gemcitabine (Gemzar) survived three times longer and had better quality of life than those who chose enzyme treatment, which included pancreatic enzymes, nutritional supplements, detoxification, and an organic diet.

    We continue our systematic development of noncommutative and nonassociative differential geometry internal to the representation category of a quasitriangular quasi-Hopf algebra. We describe derivations, differential operators, differential calculi and connections using universal categorical constructions to capture algebraic properties such as Leibniz rules. Our main result is the construction of morphisms which provide prescriptions for lifting connections to tensor products and to internal homomorphisms. We describe the curvatures of connections within our formalism, and also the formulation of Einstein-Cartan geometry as a putative framework for a nonassociative theory of gravity.

    It is essential to assure the efficacy of antimicrobials at the initial phase of therapy. However, increasing the volume of distribution (Vd) of hydrophilic antimicrobials in critically ill patients leads to reduced antimicrobial concentration in plasma and tissue, which may adversely affect the efficacy of that therapy. The aim of the present study was to establish a theoretical methodology for setting an appropriate level for initial vancomycin therapy in individual patients based on Acute Physiology and Chronic Health Evaluation (APACHE) II score. We obtained data from patients who received intravenous vancomycin for a suspected or definitively diagnosed Gram-positive bacterial infection within 72 h after admission to the intensive care unit. The Vd and elimination half-life (t 1/2) of vancomycin values were calculated using the Bayesian method, and we investigated the relationship between them and APACHE II score. There were significant correlations between APACHE II scores and Vd/actual body weight (ABW), as well as t 1/2 (r = 0.58, p < 0.05 and r = 0.74, p < 0.01, respectively). Our results suggested that the Vd and t 1/2 of vancomycin could be estimated using the following regression equations using APACHE II score.[Formula: see text] [Formula: see text]We found that APACHE II score was a useful index for predicting the Vd and t 1/2 of vancomycin, and used that to establish an initial vancomycin dosing regimen comprised of initial dose and administration interval for individual patients.

    2010-01-01

    The Department of Energy's (DOE's) Sandia National Laboratories-New Mexico (Sandia) develops science-based technologies in support of national security in areas such as nuclear weapons, nonproliferation, military technologies, and homeland security. Sandia's primary mission is ensuring that the U.S. nuclear arsenal is safe, secure, and reliable and can fully support the Nation's deterrence policy. Part of this mission includes systems engineering of nuclear weapons; research, design, and development of non-nuclear components; manufacturing of non-nuclear weapons components; the provision of safety, security, and reliability assessments of stockpile weapons; and the conduct of high-explosives research and development and environmental testing. Sandia Corporation, a subsidiary of Lockheed Martin Corporation, operates Sandia for the National Nuclear Security Administration (NNSA). On May 7, 2004, the Secretary announced that the Department would evaluate missions at DOE sites to consolidate Special Nuclear Material (SNM) in the most secure environments possible. The Administrator of the NNSA said that this effort was a key part of an overall plan to transform the nuclear weapons complex into a smaller, safer, more secure, and more efficient national security enterprise. In February 2008, Sandia was the first site to report it had reduced its on-site inventory of nuclear material below 'Categories I and II' levels, which require the highest level of security to protect material such as plutonium and highly enriched uranium. The Office of Inspector General initiated an inspection to determine if Sandia made appropriate adjustments to its security posture in response to the removal of the Categories I and II SNM. We found that Sandia adjusted its security posture in response to the removal of Categories I and II SNM. For example, security posts were closed; unneeded protective force weapons and equipment were excessed from the site; and, Sandia's Site Safeguards and

    Background Several systematic reviews suggest that intermittent pulmonary tuberculosis (TB) chemotherapy is effective, but intensity (daily versus intermittent) and duration of rifampicin use (intensive phase only versus both phases) have not been distinguished. In addition, the various outcomes (success, failure, relapse, and default) have only selectively been evaluated. Methods We conducted a meta-analysis of proportions using all four outcomes as multi-category proportions to examine the effectiveness of WHO category 1 TB treatment regimens. Database searches of studies reporting treatment outcomes of HIV negative subjects were included and stratified by intensity of therapy and duration of rifampicin therapy. Using a bias-adjusted statistical model, we pooled proportions of the four treatment outcome categories using a method that handles multi-category proportions. Results A total of 27 studies comprising of 48 data sets with 10,624 participants were studied. Overall, treatment success was similar among patients treated with intermittent (I/I) (88%) (95% CI, 81–92) and daily (D/D) (90%) (95% CI, 84–95) regimens. Default was significantly less with I/I (0%) (95% CI, 0–2) compared to D/D regimens (5%) (95% CI, 1–9). Nevertheless, I/I relapse rates (7%) (95% CI, 3–11) were higher than D/D relapse rates (1%) (95% CI, 0–3). Conclusion Treatment regimens that are offered completely intermittently versus completely daily are associated with a trade-off between treatment relapse and treatment default. There is a possibility that I/I regimens can be improved by increasing treatment duration, and this needs to be urgently addressed by future studies. PMID:26056374

    When listening to modified speech, either naturally or artificially altered, the human perceptual system rapidly adapts to it. There is some debate about the nature of the mechanisms underlying this adaptation. Although some authors propose that listeners modify their prelexical representations, others assume changes at the lexical level. Recently, Larsson, Vera, Sebastian-Galles, and Deco [Lexical plasticity in early bilinguals does not alter phoneme categories: I. Neurodynamical modelling. Journal of Cognitive Neuroscience, 20, 76-94, 2008] proposed a biologically plausible computational model to account for some existing data, one which successfully modeled how long-term exposure to a dialect triggers the creation of new lexical entries. One specific prediction of the model was that prelexical (phoneme) representations should not be affected by dialectal exposure (as long as the listener is exposed to both standard and dialectal pronunciations). Here we present a series of experiments testing the predictions of the model. Native listeners of Catalan, with extended exposure to Spanish-accented Catalan, were tested on different auditory lexical decision tasks and phoneme discrimination tasks. Behavioral and electrophysiological recordings were obtained. The results supported the predictions of our model. On the one hand, both error rates and N400 measurements indicated the existence of alternative lexical entries for dialectal varieties. On the other hand, no evidence of alterations at the phoneme level, either in the behavioral discrimination task or in the electrophysiological measurement (MMN), could be detected. The results of the present study are compared with those obtained in short-term laboratory exposures in an attempt to provide an integrative account. PMID:18855552

    Background Despite improvement with intensive multi-agent chemotherapy, 2-year progression-free survival (PFS) rates for adults with high-risk Burkitt's lymphoma (BL) remains <55%. Patients and methods We conducted a phase II trial for newly diagnosed classic BL utilizing liposomal doxorubicin (Adriamycin) in lieu of doxorubicin and incorporating intravenous rituximab (at 500 mg/m2 twice/cycle) into the CODOX-M/IVAC regimen. Correlative analyses included paired serum and cerebrospinal fluid (CSF) rituximab levels and close examination of cardiac function. Results Among 25 BL patients, the median age was 44 years (23–70) and 4 patients were HIV positive. There were 20 high-risk and 5 low-risk patients. At baseline, 40% of high-risk patients had bone marrow involvement, 35% had bulky disease and 15% had central nervous system involvement. The overall response rate was 100% (complete remission 92%). At 34-month median follow-up, the 2-year PFS and overall survival (OS) rates for all patients were 80% and 84%, respectively (low-risk: both 100%; high-risk: 76% and 81%, respectively). Furthermore, the 2-year PFS, OS, and disease-specific survival (DSS) rates for high-risk, HIV-negative patients were 84%, 89% and 100%, respectively. Adverse events (AEs) appeared to be consistent with prior CODOX-M/IVAC data, although there were several grade 3 cardiac events noted (all declined ejection fraction without clinical symptoms). The mean serum rituximab levels at 24 h after cycles 1 and 3 for patients without relapse were 258 and 306 μg/ml, respectively, versus 131 and 193 μg/ml, respectively, for patients with early progression (P = 0.002 and 0.002, respectively). The mean CSF rituximab levels for all patients were 0.11 and 0.24 μg/ml, respectively, at cycle 1 (24/72 h), which equated to serum:CSF ratios of 0.05% and 0.20%, respectively. Conclusions The integration of rituximab into CODOX-M/IVAC for adult BL was feasible and tolerable, while changes in cardiac function

    A mathematical model previously developed to test the validity of categorisation of skin test responders has been applied to data obtained from 3 age groups of Kuwaiti school children. Two specially designed sets of 4 new tuberculins were tested on senior school children to determine whether extra categories of responders might exist amongst them. Strong statistical evidence has been obtained that a proportion of the children respond to group ii, slow-grower associated antigen, creating a fourth responder category, but no evidence was found for responses to group iii, fast-grower associated antigen. The significance of group ii antigens in immune protection from tuberculosis has never been considered specifically. It is of special interest to note that responders to these antigens have been readily found in Kuwait, a country where BCG is thought to be effective, whereas no such category could be found in India or Sri Lanka, where the efficacy of the vaccine is less certain.

    Background. Recent evidence shows that use of anthracycline and taxane adjuvant chemotherapy and dose-dense regimens, consisting of more frequent administration of the drugs, have improved outcomes for breast cancer patients. In this study, we evaluated administration of an epirubicin-based regimen with paclitaxel in a sequential, dose-dense schedule as adjuvant treatment for patients with high-risk primary breast cancer. Methods. In a phase II Simon two-stage design study, we evaluated the feasibility of a modified fluorouracil, epirubicin, and cyclophosphamide (FEC) regimen at high dose intensity (fluorouracil 500 mg/m2 i.v. on days 1 and 4, epirubicin 60 mg/m2 i.v. on days 1 and 4, and cyclophosphamide 500 mg/m2 i.v. on days 1 and 4; all drugs were administered every 14 days for 3 cycles) with granulocyte colony-stimulating factor support followed by dose-intense weekly paclitaxel 100 mg/m2 for 8 cycles. In 11 patients with breast cancer following quadrantectomy (n = 8) or modified radical mastectomy (n = 3), any grade 3 (G3) or higher nonhematologic toxicity (excluding alopecia, nausea or vomiting, and bone pain, which might be a consequence of the administration of filgrastim) and adherence to the scheduled dose-dense treatment (deliverability) were monitored with the purpose of enrolling an additional 27 patients in the case of a satisfying toxicity profile and deliverability of the planned treatment (at least 7 patients completing the treatment). Results. Five of 11 patients experienced G3 or higher nonhematologic toxicity during the FEC regimen. We did not observe G3 or higher nonhematologic toxicity related to paclitaxel treatment. In particular, three patients experienced G3 fatigue, one patient had G3 oral mucositis, three patients had G3 hypokalemia, one patient had G3 syncope, one patient had G3 transaminitis (alanine aminotransferase), one patient experienced G4 pulmonary thromboembolism, and 1 patient had a G3 breast infection.

    Although amnesic H.M. typically could not recall where or when he met someone, he could recall their topics of conversation after long interference-filled delays, suggesting impaired encoding for some categories of novel events but not others. Similarly, H.M. successfully encoded into internal representations (sentence plans) some novel linguistic structures but not others in the present language production studies. For example, on the Test of Language Competence (TLC), H.M. produced uncorrected errors when encoding a wide range of novel linguistic structures, e.g., violating reliably more gender constraints than memory-normal controls when encoding referent-noun, pronoun-antecedent, and referent-pronoun anaphora, as when he erroneously and without correction used the gender-inappropriate pronoun “her” to refer to a man. In contrast, H.M. never violated corresponding referent-gender constraints for proper names, suggesting that his mechanisms for encoding proper name gender-agreement were intact. However, H.M. produced no more dysfluencies, off-topic comments, false starts, neologisms, or word and phonological sequencing errors than controls on the TLC. Present results suggest that: (a) frontal mechanisms for retrieving and sequencing word, phrase, and phonological categories are intact in H.M., unlike in category-specific aphasia; (b) encoding mechanisms in the hippocampal region are category-specific rather than item-specific, applying to, e.g., proper names rather than words; (c) H.M.’s category-specific mechanisms for encoding referents into words, phrases, and propositions are impaired, with the exception of referent gender, person, and number for encoding proper names; and (d) H.M. overuses his intact proper name encoding mechanisms to compensate for his impaired mechanisms for encoding other functionally equivalent linguistic information.

    Background Survival outcomes for patients with glioblastoma remain poor, particularly for patients with unmethylated O6-methylguanine-DNA methyltransferase (MGMT) gene promoter. This phase II, randomized, open-label, multicenter trial investigated the efficacy and safety of 2 dose regimens of the selective integrin inhibitor cilengitide combined with standard chemoradiotherapy in patients with newly diagnosed glioblastoma and an unmethylated MGMT promoter. Methods Overall, 265 patients were randomized (1:1:1) to standard cilengitide (2000 mg 2×/wk; n = 88), intensive cilengitide (2000 mg 5×/wk during wk 1−6, thereafter 2×/wk; n = 88), or a control arm (chemoradiotherapy alone; n = 89). Cilengitide was administered intravenously in combination with daily temozolomide (TMZ) and concomitant radiotherapy (RT; wk 1−6), followed by TMZ maintenance therapy (TMZ/RT→TMZ). The primary endpoint was overall survival; secondary endpoints included progression-free survival, pharmacokinetics, and safety and tolerability. Results Median overall survival was 16.3 months in the standard cilengitide arm (hazard ratio [HR], 0.686; 95% CI: 0.484, 0.972; P = .032) and 14.5 months in the intensive cilengitide arm (HR, 0.858; 95% CI: 0.612, 1.204; P = .3771) versus 13.4 months in the control arm. Median progression-free survival assessed per independent review committee was 5.6 months (HR, 0.822; 95% CI: 0.595, 1.134) and 5.9 months (HR, 0.794; 95% CI: 0.575, 1.096) in the standard and intensive cilengitide arms, respectively, versus 4.1 months in the control arm. Cilengitide was well tolerated. Conclusions Standard and intensive cilengitide dose regimens were well tolerated in combination with TMZ/RT→TMZ. Inconsistent overall survival and progression-free survival outcomes and a limited sample size did not allow firm conclusions regarding clinical efficacy in this exploratory phase II study.

    In an open-label, 24-week, parallel-group study, 135 patients inadequately controlled with oral antihyperglycemic medications (OAMs) were treated with maximally tolerated doses of metformin and glibenclamide for at least 8 weeks and then randomized to bedtime neutral protamine Hagedorn (NPH) insulin plus maximally tolerated dose of glibenclamide BID (glib/NPH group) or insulin lispro mix 50 (50% lispro, 50% insulin lispro protamine suspension [ILPS]) pre-breakfast and lispro mix 25 (25% lispro, 75% ILPS) pre-dinner (LM50/LM25 group) (both OAMs discontinued). The LM50/LM25 group had significantly lower 2-hour postprandial BG (both meals combined) compared with glib/NPH after 12 (11.70+/-3.40 mmol/L vs. 13.15+/-2.44 mmol/L, p=0.010) and 24 weeks (11.13+/-3.31 mmol/L vs. 14.46+/-2.93 mmol/L, p =0.0001). Both regimens significantly decreased HbA1c. The reduction was greater with LM50/LM25 (-1.31+/-2% vs. -0.5+/-1.6%; P=0.01). At endpoint, the overall hypoglycemia rate increased with LM50/LM25 and decreased with glib/NPH compared with baseline (0.22+/-0.9 vs. -0.08+/-0.72 episodes/patient/30 days; p =0.037). Treatment with LM50/LM25 compared with glib/NPH in patients with inadequate control on combined OAMs yielded better postprandial and overall glycemic control with a higher rate of hypoglycemia.

    2008-09-01

    Purpose: 5-Fluorouracil (5-FU) + mitomycin C (MMC)-based chemoradiotherapy is standard treatment for patients with epidermoid anal carcinoma. Clinical trials in other cancers have confirmed 5-FU can successfully be replaced by the oral fluoropyrimidine capecitabine. This phase II trial aimed to determine the feasibility, toxicity, and efficacy of capecitabine, MMC and radiotherapy (RT) in anal cancer patients. Methods and Materials: Radiotherapy comprised the schedule of the UK Anal Cancer Trial (ACT) II trial (50.4 Gy in 28 fractions of 1.8 Gy). With MMC (12 mg/m{sup 2}) on Day 1 and capecitabine on each RT treatment day in two divided doses (825 mg/m{sup 2} b.i.d). The endpoints were complete response at 4 weeks, local control at 6 months and toxicity. Results: Thirty-one patients entered the trial. The median age was 61 years (range 45-86) with 14 males and 17 females. Compliance with chemotherapy with no dose interruptions or delays was 68%, and with RT was 81%. Eighteen (58%) patients completed both modalities of treatment as planned. Dose-limiting Grade 3 or 4 diarrhea was seen in 1 of 31 patients. Three patients experienced Grade 3 neutropenia. There were no treatment-related deaths. Four weeks following completion of chemoradiation, 24 patients (77%) had a complete clinical response, and 4 (16%) a partial response. With a median follow-up of 14 months, three locoregional relapses occurred. Conclusions: Capecitabine with MMC and RT in with patients anal carcinoma is well tolerated, with minimal toxicity and acceptable compliance. We recommend testing this schedule in future national Phase III studies in anal cancer.

    Purpose The strategy of definitive chemoradiation with selective surgical salvage in locoregionally advanced esophageal cancer was evaluated in a Phase II trial in Radiation Therapy Oncology Group (RTOG)-affiliated sites. Methods and Materials The study was designed to detect an improvement in 1-year survival from 60% to 77.5% (α= 0.05; power = 80%). Definitive chemoradiation involved induction chemotherapy with 5-fluorouracil (5-FU) (650 mg/mg2/day), cisplatin (15 mg/mg2/day), and paclitaxel (200 mg/mg2/day) for two cycles, followed by concurrent chemoradiation with 50.4 Gy (1.8 Gy/fraction) and daily 5-FU (300 mg/mg2/day) with cisplatin (15 mg/mg2/day) over the first 5 days. Salvage surgical resection was considered for patients with residual or recurrent esophageal cancer who did not have systemic disease. Results Forty-three patients with nonmetastatic resectable esophageal cancer were entered from Sept 2003 to March 2006. Forty-one patients were eligible for analysis. Clinical stage was ≥T3 in 31 patients (76%) and N1 in 29 patients (71%), with adenocarcinoma histology in 30 patients (73%). Thirty-seven patients (90%) completed induction chemotherapy followed by concurrent chemoradiation. Twenty-eight patients (68%) experienced Grade 3+ nonhematologic toxicity. Four treatment-related deaths were noted. Twenty-one patients underwent surgery following definitive chemoradiation because of residual (17 patients) or recurrent (3 patients) esophageal cancer,and 1 patient because of choice. Median follow-up of live patients was 22 months, with an estimated 1-year survival of 71%. Conclusions In this Phase II trial (RTOG 0246) evaluating selective surgical salvage after definitive chemoradiation in locoregionally advanced esophageal cancer, the hypothesized 1-year RTOG survival rate (77.5%) was not achieved (1 year, 71%; 95% confidence interval< 54%–82%).

    Purpose The phase III North American Intergroup E2496 Trial (Combination Chemotherapy With or Without Radiation Therapy in Treating Patients With Hodgkin's Lymphoma) compared doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with mechlorethamine, doxorubicin, vincristine, bleomycin, vinblastine, etoposide, and prednisone (Stanford V). We report results of a planned subgroup analysis in patients with stage I or II bulky mediastinal Hodgkin lymphoma (HL). Patients and Methods Patients were randomly assigned to six to eight cycles of ABVD every 28 days or Stanford V once per week for 12 weeks. Two to 3 weeks after completion of chemotherapy, all patients received 36 Gy of modified involved field radiotherapy (IFRT) to the mediastinum, hila, and supraclavicular regions. Patients on the Stanford V arm received IFRT to additional sites ≥ 5 cm at diagnosis. Primary end points were failure-free survival (FFS) and overall survival (OS). Results Of 794 eligible patients, 264 had stage I or II bulky disease, 135 received ABVD, and 129 received Stanford V. Patient characteristics were matched. The overall response rate was 83% with ABVD and 88% with Stanford V. At a median follow-up of 6.5 years, the study excluded a difference of more than 21% in 5-year FFS and more than 16% in 5-year OS between ABVD and Stanford V (5-year FFS: 85% v 79%; HR, 0.68; 95% CI, 0.37 to 1.25; P = .22; 5-year OS: 96% v 92%; HR, 0.49; 95% CI, 0.16 to 1.47; P = .19). In-field relapses occurred in < 10% of the patients in each arm. Conclusion For patients with stage I or II bulky mediastinal HL, no substantial statistically significant differences were detected between the two regimens, although power was limited. To the best of our knowledge, this is the first prospective trial reporting outcomes specific to this subgroup, and it sets a benchmark for comparison of ongoing and future studies. PMID:25897153

    A multicentre, single-arm, phase II trial designed to determine the efficacy of single-agent vinflunine in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with a platinum-based regimen. The objectives were to assess efficacy in terms of tumour response rate (primary end point), duration of response, progression-free survival (PFS) and overall survival (OS), and to evaluate the toxicity associated with this treatment. Patients with advanced NSCLC with progressive disease having failed prior platinum-based first-line treatment for advanced disease. Five responses out of the 63 treated patients were documented by WHO criteria and validated by an independent panel review (IRP), yielding a response rate of 7.9% (95% CI: 2.6–17.6) in the intent-to-treat analysis and 8.3% (95% CI: 2.8–18.4) in the evaluable population. Disease control was achieved in 35 out of 60 evaluable patients (58.3%). The median duration of response (complete response+partial response), according to modified WHO criteria was 7.8 months (95% CI: 4.6–NR). Median PFS was 2.6 months (95% CI: 1.4–3.8), and the median survival was 7.0 months (95% CI: 5.8–9.2). Grades 3–4 neutropenia was reported in 50% of patients; febrile neutropenia was observed in two patients (3.2%); grades 3–4 myalgia and grade 3 constipation were experienced by 10 (15.9%) and six (9.5%) of patients, respectively. Constipation was manageable, noncumulative and could be prevented with laxative prophylaxis. The encouraging results from this phase II study with vinflunine warrant further investigations in phase III trials as second- or first-line treatment of advanced non-small-cell lung carcinoma, as a single agent or in combination with other active drugs.

    This paper presents Ramsey theory in category-theoretic terms as a message from a non-expert author to a non-expert reader. Everything is explained starting from the level zero, and an attempt is made to be as self-explanatory in the terminology and notation as possible. For the sake of references, the paper also reproduces traditional terminology, with concepts and theorems often named after (presumed) discoverers who are largely unknown to outsiders to the field. The sources are referred to in a manner so as to make them easy to find on the web; only exceptionally are non-freely accessible items referred to. Certain questions are formulated as 'conjectures', not out of a deep belief in their validity but because they sound better stated explicitly. There are no new results in this article, no deepening of particular aspects of Ramsey theory, no attempts to be comprehensive. But, in the spirit of the ideas of Anatoly Vershik, an attempt is made to move transversally across common directions of research, to see interrelations between them and to formulate questions. In fact, the article reproduces a chapter from the author's as yet unfinished manuscript "A number of questions". Bibliography: 65 titles.

    This trial was designed to compare the efficacy and safety between epirubicin (E) and carboplatin (C) in combination with paclitaxel (P) and trastuzumab (H) in neoadjuvant setting. In 13 Chinese cancer centers, 100 patients with HER2-positive, locally advanced breast cancer were 1:1 randomized to receive medication as follows: trastuzumab and paclitaxel weekly combined with carboplatin weekly for PCH group, or epirubicin every 3 weeks for PEH group. Patients were given 4 to 6 cycles of chemotherapy. The primary endpoint was pathologic complete response (pCR) rate, which was no significant difference in PCH and PEH regimen (39.1% vs. 48.8%; p=0.365). However, PEH regimen achieved higher pCR in luminal-B (HER2-poitive) subgroup (55.0% vs. 24.0%; p = 0.033), but not in ERBB2+ subgroup (42.9% vs. 57.1%; p = 0.355). PEH regimen showed a favorable efficacy in PIK3CA mutated subgroup (69.2% vs.23.5%, p=0.012). No significant difference was observed in the subgroup analysis of TP53 mutation status, PTEN expression, FCGR2A SNP and FCGR3A SNP. Both regimens as neoadjuvant chemotherapy achieve similar efficacy and safety. PEH might improve pCR rate, especially in the luminal-B subtype and PIK3CA mutation subtype. PEH is feasible and less likely to increase the incidence of acute cardiac events compared to PCH. PMID:26084292

    This paper presents Facility Management, Readiness Assessment, and Authorization Basis experience gained and lessons learned during the Heavy Element Facility Risk Reduction Program (RRP). The RRP was tasked with removing contaminated glove boxes, radioactive inventory, and contaminated ventilation systems from the Heavy Element Facility (B251) at Lawrence Livermore National Laboratory (LLNL). The RRP was successful in its goal in April 2005 with the successful downgrade of B251 from a Category II Nuclear Facility to a Radiological Facility. The expertise gained and the lessons learned during the planning and conduct of the RRP included development of unique approaches in work planning/work control (''Expect the unexpected and confirm the expected'') and facility management. These approaches minimized worker dose and resulted in significant safety improvements and operational efficiencies. These lessons learned can help similar operational and management activities at other sites, including facilities restarting operations or new facility startup. B251 was constructed at LLNL to provide research areas for conducting experiments in radiochemistry using transuranic elements. Activities at B251 once included the preparation of tracer sets associated with the underground testing of nuclear devices and basic research devoted to a better understanding of the chemical and nuclear behavior of the transuranic elements. Due to the age of the facility, even with preventative maintenance, facility safety and experimental systems were deteriorating. A variety of seismic standards were used in the facility design and construction, which encompassed eight building increments constructed over a period of 26 years. The cost to bring the facility into compliance with the current seismic and other requirements was prohibitive, and simply maintaining B251 as a Category II nuclear facility posed serious cost considerations under a changing regulatory environment. Considering the high

    Many studies have demonstrated the importance of the knowledge that interrelates features in people's mental representation of categories and that makes our conception of categories coherent. This article focuses on abstract coherent categories, coherent categories that are also abstract because they are defined by relations independently of any features. Four experiments demonstrate that abstract coherent categories are learned more easily than control categories with identical features and statistical structure, and also that participants induced an abstract representation of the category by granting category membership to exemplars with completely novel features. The authors argue that the human conceptual system is heavily populated with abstract coherent concepts, including conceptions of social groups, societal institutions, legal, political, and military scenarios, and many superordinate categories, such as classes of natural kinds.

    We show that boundary conditions in topological open string theory on Calabi--Yau (CY) manifolds are objects in the derived category of coherent sheaves, as foreseen in the homological mirror symmetry proposal of Kontsevich. Together with conformal field theory considerations, this leads to a precise criterion determining the supersymmetry preserving branes at any point in CY moduli space, completing the proposal of II-stability.

    Locally advanced breast cancer (LABC) is a good setting in which to monitor response to neoadjuvant chemotherapy, to downsize the tumor (which facilitates breast-conserving surgery), and to test newer agents in untreated patients. Eribulin (E) has shown activity in patients who have undergone previous taxane, anthracycline, and capecitabine treatment. We aimed to evaluate the neoadjuvant use of E followed by doxorubicin and cyclophosphamide (AC) in patients with HER2-negative LABC, using as a control a randomized group of women who received weekly paclitaxel (WP). Fifty women with LABC were accrued January-August 2013. Patients were randomized (1:2) to receive either WP (N = 19) for 12 treatments or E (N = 31) every 3 weeks for 4 cycles followed by AC every 3 weeks for 4 cycles before surgery. 17/19 patients who took WP and 25/30 who took E completed all cycles. Patients were evaluated by clinical examination and breast MRI at baseline and after completion of E or WP. Surgical pCR in breast and lymph nodes was determined by a local pathologist following chemotherapy. Forty-nine patients received ≥1 dose of neoadjuvant chemotherapy and are included in this analysis. Forty-eight underwent surgery; one had disease that was inoperable (on E) and is included as no-pCR patient. 17/19 of these patients who took WP completed 12 doses; 28/30 on E completed 4 cycles. Six discontinued treatment on WP, E, or AC. Both treatments were well tolerated. pCR on WP = 5/19(26 %) and on E = 5/30(17 %). Both regimens were equally well tolerated with no unexpected toxicities. pCR did not suggest higher activity with E than with other standard regimens in these LABC patients. PMID:26126970

  17. Incidental Auditory Category Learning

    2015-01-01

    Very little is known about how auditory categories are learned incidentally, without instructions to search for category-diagnostic dimensions, overt category decisions, or experimenter-provided feedback. This is an important gap because learning in the natural environment does not arise from explicit feedback and there is evidence that the learning systems engaged by traditional tasks are distinct from those recruited by incidental category learning. We examined incidental auditory category learning with a novel paradigm, the Systematic Multimodal Associations Reaction Time (SMART) task, in which participants rapidly detect and report the appearance of a visual target in one of four possible screen locations. Although the overt task is rapid visual detection, a brief sequence of sounds precedes each visual target. These sounds are drawn from one of four distinct sound categories that predict the location of the upcoming visual target. These many-to-one auditory-to-visuomotor correspondences support incidental auditory category learning. Participants incidentally learn categories of complex acoustic exemplars and generalize this learning to novel exemplars and tasks. Further, learning is facilitated when category exemplar variability is more tightly coupled to the visuomotor associations than when the same stimulus variability is experienced across trials. We relate these findings to phonetic category learning. PMID:26010588

    Tuberculosis is an airborne infectious disease treated with combination therapeutic regimens. Adherence to long-term antituberculosis therapy is crucial for maintaining adequate blood drug level. The emergence and spread of drug-resistant Mycobacterium tuberculosis strains are mainly favored by the inadequate medical management of the patients. The therapeutic approach for drug-resistant tuberculosis is cumbersome, because of the poor, expensive, less-effective, and toxic alternatives to the first-line drugs. New antituberculosis drugs (bedaquiline and delamanid) have been recently approved by the health authorities, but they cannot represent the definitive solution to the clinical management of drug-resistant tuberculosis forms, particularly in intermediate economy settings where the prevalence of drug resistance is high (China, India, and former Soviet Union countries). New research and development activities are urgently needed. Public health policies are required to preserve the new and old therapeutic options. PMID:25573773

    Existing research on categories has only examined indirectly the value associated with being a member of a category relative to the value of the set of attributes that determine membership in that category. This study uses survey data to analyze consumers' preferences for the "organic” label versus for the attributes underlying that label. We found that consumers generally preferred products with the category label to those with the attributes required for the organic label but without the label. We also found that the value accorded to the organic label increased with the number of attributes that an individual associated with the category. Category membership nevertheless still had greater value than even that of the sum of the attributes associated with it. PMID:25111831

    This experiment investigated whether macaque monkeys partition the photic spectrum into the same four basic hue categories that humans do, i.e., blue, green, yellow, and red. Monkeys were trained to respond in the presence of one chromatic stimulus and were tested, in extinction, for generalization to others. In extinction, the monkeys responded at similar and high levels to stimuli that fell in the same basic human hue category as the training stimulus and at similar and much lower levels to stimuli that fell in a different human hue category from the training stimulus. It was concluded that macaques and humans categorize the spectrum in a similar fashion. PMID:113431

    The aim of this study was to investigate the dietary regimens reported by athletes competing at a major international competition and report whether these were based on nutrient composition, religious beliefs, cultural eating style, food intolerance or avoidance of certain ingredients. A questionnaire was randomly distributed to 351 athletes in the main dining hall of the athletes' village over the three main meal periods during the Delhi 2010 Commonwealth Games (23rd Sept-14th Oct, 2010). The majority (n = 218, 62%) of athletes reported following one or more dietary regimens, with 50% (n = 174) following a diet based on the nutrient composition of the food. Significantly more athletes from weight category and aesthetic sports (28%, p = .005) and from power/sprint sports (41%, p = .004) followed low fat and high protein regimens respectively. Other specialized dietary regimens were followed by 33% of participants, with avoidance of red meat (13%), vegetarian (7%), Halal (6%), and low lactose regimens (5%) reported most frequently. Significantly more athletes from non-Western regions followed a vegetarian diet (p < .001), while more vegetarians reported avoiding additives (p = .013) and wheat (p ≤ .001). A Western style of eating was the most commonly reported cultural regimen (72% of total with 23% from non-Western regions). Those following a Western diet were significantly more likely to report following a regimen based on nutrient composition (p = .02). As a high proportion of athletes from differing countries and sports follow specialized dietary regimens, caterers and organizers should ensure that adequate nutrition support and food items are available at similar events.

    Given a II1-subfactor of arbitrary index, we show that the rectangular GICAR category, also called the rectangular planar rook category, faithfully embeds as A - A bimodule maps among the bimodules . As a corollary, we get a lower bound on the dimension of the centralizer algebras for infinite index subfactors, and we also get that is nonabelian for , where is the Jones tower for . We also show that the annular GICAR/planar rook category acts as maps amongst the A-central vectors in , although this action may be degenerate. We prove these results in more generality using bimodules. The embedding of the GICAR category builds on work of Connes and Evans, who originally found GICAR algebras inside Temperley-Lieb algebras with finite modulus.

  7. Learning, retention, and generalization of haptic categories

    NASA Astrophysics Data System (ADS)

    Do, Phuong T.

    This dissertation explored how haptic concepts are learned, retained, and generalized to the same or different modality. Participants learned to classify objects into three categories either visually or haptically via different training procedures, followed by an immediate or delayed transfer test. Experiment I involved visual versus haptic learning and transfer. Intermodal matching between vision and haptics was investigated in Experiment II. Experiments III and IV examined intersensory conflict in within- and between-category bimodal situations to determine the degree of perceptual dominance between sight and touch. Experiment V explored the intramodal relationship between similarity and categorization in a psychological space, as revealed by MDS analysis of similarity judgments. Major findings were: (1) visual examination resulted in relatively higher performance accuracy than haptic learning; (2) systematic training produced better category learning of haptic concepts across all modality conditions; (3) the category prototypes were rated newer than any transfer stimulus followed learning both immediately and after a week delay; and, (4) although they converged at the apex of two transformational trajectories, the category prototypes became more central to their respective categories and increasingly structured as a function of learning. Implications for theories of multimodal similarity and categorization behavior are discussed in terms of discrimination learning, sensory integration, and dominance relation.

    Inhaled corticosteroids are the cornerstone of asthma management. Inhaled corticosteroid regimens differ slightly in various international guidelines on asthma management but are based on the principles of continuous treatment and titration to the lowest effective dose. Several recent studies, nevertheless, appear to demonstrate the potential value of preemptive or "pro re nata" regimens in infants and children. These studies were included in GINA 2015 for children 5 years of age and younger in whom discontinuous treatment is proposed as a second-line option.

    2015-07-01

    Shushu is a Turkish Cypriot drag performance artist and the article begins with a discussion of a short film about him by a Greek Cypriot playwright, film maker, and gay activist. The film is interesting in its own right as a documentary about a complex personality, but it is also relevant to wider discussion of sexual and gender identity and categorization in a country divided by history, religion, politics, and military occupation. Shushu rejects easy identification as gay or transgender, or anything else. He is his own self. But refusing a recognized and recognizable identity brings problems, and I detected a pervasive mood of melancholy in his portrayal. The article builds from this starting point to explore the problematic nature of identities and categorizations in the contemporary world. The analysis opens with the power of words and language in defining and classifying sexuality. The early sexologists set in motion a whole catalogue of categories which continue to shape sexual thinking, believing that they were providing a scientific basis for a more humane treatment of sexual variations. This logic continues in DSM-5. The historical effect, however, has been more complex. Categorizations have often fixed individuals into a narrow band of definitions and identities that marginalize and pathologize. The emergence of radical sexual-social movements from the late 1960s offered new forms of grassroots knowledge in opposition to the sexological tradition, but at first these movements worked to affirm rather than challenge the significance of identity categories. Increasingly, however, identities have been problematized and challenged for limiting sexual and gender possibilities, leading to the apparently paradoxical situation where sexual identities are seen as both necessary and impossible. There are emotional costs both in affirming a fixed identity and in rejecting one. Shushu is caught in this dilemma, leading to the pervasive sense of loss that shapes the

    A trial was conducted to determine the effects of different rearing feed regimens on plasma hormone and metabolite levels and hepatic lipid metabolism and gene expression on sexually mature broiler breeders. Cobb 500 birds were divided into 2 groups at 4 wk and fed either an everyday (ED) or skip-a-day (SKP) regimen. At 24 wk of age, all birds were switched over to an ED regimen. At 26.4 wk, breeder hens were randomly selected and killed at intervals after feeding. Livers were sampled from 4 hens at 4-h intervals for 24 h for a total of 28 samples per treatment. Blood was sampled from 4 hens per sampling time; sampling times were 0, 30, and 60 min and 2 and 4 h after feeding and then every 4 h up to 24 h for a total of 36 samples per treatment. Main feeding regimen, time, and interaction effects were analyzed. Significant interaction effects were found between time and feeding regimen for acetyl-coenzyme A carboxylase and malic enzyme mRNA expression. The peak for acetyl-coenzyme A carboxylase expression was higher in ED-reared birds, whereas the peak for malic enzyme expression was higher in SKP-reared birds. Overall, plasma levels of insulin-like growth factor-II were higher in SKP-reared birds. Overall, plasma corticosterone levels were also higher in SKP-reared birds and significant interaction effects between time and feeding regimen were seen. The expression of apolipoprotein A1 was significantly higher in ED-reared birds: significant interaction effects were also noted. Other researchers also found some of the differences observed in the present study in 16-wk-old pullets. In summary, different feeding regimens alter metabolic responses, some of which carry over into sexual maturity. PMID:20460664

    Objective Clinical studies of patients with bone sarcomas have been challenged by insufficient numbers at individual centres to draw valid conclusions. Our objective was to assess the feasibility of conducting a definitive multi-centre randomised controlled trial (RCT) to determine whether a five-day regimen of post-operative antibiotics, in comparison to a 24-hour regimen, decreases surgical site infections in patients undergoing endoprosthetic reconstruction for lower extremity primary bone tumours. Methods We performed a pilot international multi-centre RCT. We used central randomisation to conceal treatment allocation and sham antibiotics to blind participants, surgeons, and data collectors. We determined feasibility by measuring patient enrolment, completeness of follow-up, and protocol deviations for the antibiotic regimens. Results We screened 96 patients and enrolled 60 participants (44 men and 16 women) across 21 sites from four countries over 24 months (mean 2.13 participants per site per year, standard deviation 2.14). One participant was lost to follow-up and one withdrew consent. Complete data were obtained for 98% of eligible patients at two weeks, 83% at six months, and 73% at one year (the remainder with partial data or pending queries). In total, 18 participants missed at least one dose of antibiotics or placebo post-operatively, but 93% of all post-operative doses were administered per protocol. Conclusions It is feasible to conduct a definitive multi-centre RCT of post-operative antibiotic regimens in patients with bone sarcomas, but further expansion of our collaborative network will be critical. We have demonstrated an ability to coordinate in multiple countries, enrol participants, maintain protocol adherence, and minimise losses to follow-up.

    The currently advocated rabies post-exposure prophylaxis regimens are of one month duration with reduced patient compliance. WHO recommended research on shortened vaccination regimens which have a practical and economic advantage over the existing regimens. Hence, the present study was undertaken to assess the safety and immunogenicity of 2 WHO prequalified rabies vaccines administered by one week, 4 site intra dermal regimen (4-4-4-0-0) in animal bite cases. This study was a comparative, open label, phase III, randomized clinical trial conducted at Anti rabies clinic, KIMS Hospital, Bangalore, India. The study was registered in Clinical Trials Registry of India (CTRI) bearing the registration number CTRI/2012/12/003230. Ninety subjects with category II/III animal bites/exposures were enrolled. Equine rabies immunoglobulin was administered to all category III exposures. 0.1 mL of either purified chick embryo cell vaccine (Rabipur) or purified verocell rabies vaccine (Verorab) was administered intradermally into 4 sites on days 0, 3 and 7 to all the study subjects. Serum of subjects collected on day 0, 14, 90 and 365 were analyzed for rabies virus neutralizing antibody (RVNA) concentration. The incidence of ADR in Rabipur and Verorab group was 2.96% and 1.14% respectively. In Rabipur group, geometric mean concentration (95% confidence interval) of RVNA was 14.5 (13.50, 15.57), 11.78 (11.27, 12.31) and 5.95 (5.50, 6.44) IU/mL on days 14, 90 and 365 respectively; In Verorab group geometric mean concentration (95% confidence interval) of RVNA was 14.43 (13.41, 15.53), 11.93 (11.47, 12.40) and 5.67 (5.29, 6.08) IU/mL on days 14, 90 and 365 respectively.

    The currently advocated rabies post-exposure prophylaxis regimens are of one month duration with reduced patient compliance. WHO recommended research on shortened vaccination regimens which have a practical and economic advantage over the existing regimens. Hence, the present study was undertaken to assess the safety and immunogenicity of 2 WHO prequalified rabies vaccines administered by one week, 4 site intra dermal regimen (4-4-4-0-0) in animal bite cases. This study was a comparative, open label, phase III, randomized clinical trial conducted at Anti rabies clinic, KIMS Hospital, Bangalore, India. The study was registered in Clinical Trials Registry of India (CTRI) bearing the registration number CTRI/2012/12/003230. Ninety subjects with category II/III animal bites/exposures were enrolled. Equine rabies immunoglobulin was administered to all category III exposures. 0.1 mL of either purified chick embryo cell vaccine (Rabipur) or purified verocell rabies vaccine (Verorab) was administered intradermally into 4 sites on days 0, 3 and 7 to all the study subjects. Serum of subjects collected on day 0, 14, 90 and 365 were analyzed for rabies virus neutralizing antibody (RVNA) concentration. The incidence of ADR in Rabipur and Verorab group was 2.96% and 1.14% respectively. In Rabipur group, geometric mean concentration (95% confidence interval) of RVNA was 14.5 (13.50, 15.57), 11.78 (11.27, 12.31) and 5.95 (5.50, 6.44) IU/mL on days 14, 90 and 365 respectively; In Verorab group geometric mean concentration (95% confidence interval) of RVNA was 14.43 (13.41, 15.53), 11.93 (11.47, 12.40) and 5.67 (5.29, 6.08) IU/mL on days 14, 90 and 365 respectively. In conclusion, Rabipur and Verorab were found to be safe, immunogenic and comparable with each other, when administered using one week, 4 site intradermal regimen (4-4-4-0-0) in animal bite cases.

    Strategies involving new drug combinations, as well as new uses of existing drugs, are urgently needed to reduce the time required to cure patients with drug-sensitive or multidrug-resistant (MDR) tuberculosis (TB). We compared the sterilizing activity of the standard first-line antitubercular regimen, rifampin-isoniazid-pyrazinamide (RHZ), with that of the novel regimen PA-824–moxifloxacin–pyrazinamide (PaMZ), which is currently being studied in clinical trials (NCT01498419), in the guinea pig model of chronic TB infection, in which animals develop necrotic granulomas histologically resembling their human counterparts. Guinea pigs were aerosol infected with ∼2 log10 bacilli of wild-type Mycobacterium tuberculosis H37Rv, and antibiotic treatment was initiated 6 weeks after infection. Separate groups of animals received RHZ, PaMZ, or single or two-drug components of the latter regimen administered at human-equivalent doses 5 days/week for a total of 8 weeks. Relapse rates were assessed 3 months after discontinuation of treatment to determine the sterilizing activity of each combination regimen. PaMZ given at human-equivalent doses was safe and well tolerated for the entire treatment period and rendered guinea pig lungs culture negative more rapidly than RHZ did. After 1 month of treatment, 80% and 50% of animals in the RHZ and PaMZ groups, respectively, had lung culture-positive relapse. Both combination regimens prevented microbiological relapse when administered for a total of 2 months. Our data support the use of PaMZ as a novel isoniazid- and rifamycin-sparing regimen suitable for treatment of both drug-sensitive TB and MDR-TB. PMID:23733473

    A 76-year-old Japanese woman presented to our hospital with anorexia. Two years before, she was diagnosed with non-Hodgkin’s lymphoma and had received ten cycles of systemic chemotherapy. After salvage chemotherapy with bendamustine and rituximab (B–R), bone marrow suppression had lasted >3 months. Esophagogastroscopy revealed polynesic white protrusions in the mid-esophagus. These lesions were diagnosed as herpetic esophagitis. To the best of our knowledge, there is no other report in which herpetic esophagitis has been documented as an adverse event of B–R regimen. Because the complication could cause symptomatic gastrointestinal discomfort, physicians should be aware of this disease. PMID:27330298

    In one form of category-based induction, people make predictions about unknown properties of objects. There is a tension between predictions made based on the object’s specific features (e.g., objects above a certain size tend not to fly) and those made by reference to category-level knowledge (e.g., birds fly). Seven experiments with artificial categories investigated these two sources of induction by looking at whether people used information about correlated features within categories, suggesting that they focused on feature-feature relations rather than summary categorical information. The results showed that people relied heavily on such correlations, even when there was no reason to think that the correlations exist in the population. The results suggested that people’s use of this strategy is largely unreflective, rather than strategically chosen. These findings have important implications for models of category-based induction, which generally ignore feature-feature relations. PMID:20526447

  1. Evidence-Based Development and Rationale for Once-Daily Rivaroxaban Dosing Regimens Across Multiple Indications

    PubMed Central

    Berkowitz, Scott D.; Misselwitz, Frank

    2016-01-01

    Background: Rivaroxaban, a direct factor Xa inhibitor, has been developed to meet clinical needs in a broad range of indications in adults: prevention of venous thromboembolism after elective hip or knee replacement surgery, treatment and secondary prevention of venous thromboembolism, prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation having one or more risk factors, and in Europe, prevention of atherothrombotic events after an acute coronary syndrome in patients with elevated cardiac biomarkers. However, the precise dose and regimen vary with the indication, leading to this effort to provide clarity concerning the appropriate use of rivaroxaban. This article reviews the clinical development program for rivaroxaban and summarizes the evidence for each approved, indication-specific dose regimen. Results: Although initially investigated for twice-daily dosing, early observations, including the finding that the pharmacodynamic effects of rivaroxaban last longer than the elimination half-life, suggested that once-daily dosing might be attainable and effective. These observations were evaluated within the extensive phase II program, which, together with pharmacology studies, provides the evidence underpinning the selection of once-daily regimens for most, but not all, of the approved clinical indications for rivaroxaban. Conclusion: The evidence for each dosing regimen demonstrates that although pharmacology studies are of paramount importance, dose regimens must be subjected to careful empirical validation. Once-daily dosing was shown to be clinically appropriate for most rivaroxaban indications. Furthermore, a “one size fits all” approach to dosing frequency is unlikely to result in a regimen that yields optimal patient outcomes across different indications. PMID:26893445

  2. Treatment regimens of classical and newer taxanes.

    2016-02-01

    The classical taxanes (paclitaxel, docetaxel), the newer taxane cabazitaxel and the nanoparticle-bound nab-paclitaxel are among the most widely used anticancer drugs. The taxanes share the characteristics of extensive hepatic metabolism and biliary excretion, the need for dose adaptation in patients with liver dysfunction, and a substantial pharmacokinetic variability even after taking into account known covariates. Data from clinical studies suggest that optimal scheduling of the taxanes is dependent not only on the specific taxane compound, but also on the tumor type and line of treatment. Still, the optimal dosing regimen (weekly vs 3 weekly) and optimal dose of the taxanes are controversial, as is the value of pharmacological personalization of taxane dosing. In this article, an overview is given on the pharmacological properties of the taxanes, including metabolism, pharmacokinetics-pharmacodynamics and aspects in the clinical use of taxanes. The latter includes the ongoing debate on the most active and safe regimen, the recommended initial dose and the issue of therapeutic drug dosing. PMID:26589792

    Motivated by the relation between the Drinfeld double and central property (T) for quantum groups, given a rigid C*-tensor category {mathcal{C}} and a unitary half-braiding on an ind-object, we construct a *-representation of the fusion algebra of {mathcal{C}}. This allows us to present an alternative approach to recent results of Popa and Vaes, who defined C*-algebras of monoidal categories and introduced property (T) for them. As an example we analyze categories {mathcal{C}} of Hilbert bimodules over a II1-factor. We show that in this case the Drinfeld center is monoidally equivalent to a category of Hilbert bimodules over another II1-factor obtained by the Longo-Rehren construction. As an application, we obtain an alternative proof of the result of Popa and Vaes stating that property (T) for the category defined by an extremal finite index subfactor {N subset M} is equivalent to Popa's property (T) for the corresponding SE-inclusion of II1-factors. In the last part of the paper we study Müger's notion of weakly monoidally Morita equivalent categories and analyze the behavior of our constructions under the equivalence of the corresponding Drinfeld centers established by Schauenburg. In particular, we prove that property (T) is invariant under weak monoidal Morita equivalence.

  7. The neurobiology of category learning.

    Ashby, F Gregory; Spiering, Brian J

    2004-06-01

    Many recent studies have examined the neural basis of category learning. Behavioral neuroscience results suggest that both the prefrontal cortex and the basal ganglia play important category-learning roles; neurons that develop category-specific firing properties are found in both regions, and lesions to both areas cause category-learning deficits. Similar studies indicate that the inferotemporal cortex does not mediate the learning of new categories. The cognitive neuroscience literature on category learning appears contradictory until the results are partitioned according to the type of category-learning task that was used. Three major tasks can be identified: rule based, information-integration, and prototype-distortion. Recent results are consistent with the hypotheses that (a) learning in rule-based tasks requires working memory and executive attention and is mediated by frontal-striatal circuits, (b) learning in information-integration tasks requires procedural memory and is mediated primarily within the basal ganglia, and (c) learning in prototype-distortion tasks depends on multiple memory systems, including the perceptual representation system.

    Controlling effects of drugs administered in combination is particularly challenging with a densified regimen because of life-threatening hematological toxicities. We have developed a mathematical model to optimize drug dosing regimens and to redesign the dose intensification-dose escalation process, using densified cycles of combined anticancer drugs. A generic mathematical model was developed to describe the main components of the real process, including pharmacokinetics, safety and efficacy pharmacodynamics, and non-hematological toxicity risk. This model allowed for computing the distribution of the total drug amount of each drug in combination, for each escalation dose level, in order to minimize the average tumor mass for each cycle. This was achieved while complying with absolute neutrophil count clinical constraints and without exceeding a fixed risk of non-hematological dose-limiting toxicity. The innovative part of this work was the development of densifying and intensifying designs in a unified procedure. This model enabled us to determine the appropriate regimen in a pilot phase I/II study in metastatic breast patients for a 2-week-cycle treatment of docetaxel plus epirubicin doublet, and to propose a new dose-ranging process. In addition to the present application, this method can be further used to achieve optimization of any combination therapy, thus improving the efficacy versus toxicity balance of such a regimen.

    The U.S. National Ocean Policy calls for a science- and ecosystem-based approach to comprehensive planning and management of human activities and their impacts on America’s oceans. The Ocean Community in Data.gov is an outcome of 2010–2011 work by an interagency working group charged with designing a national information management system to support ocean planning. Within the working group, a smaller team developed a list of the data categories specifically relevant to marine planning. This set of categories is an important consensus statement of the breadth of information types required for ocean planning from a national, multidisciplinary perspective. Although the categories were described in a working document in 2011, they have not yet been fully implemented explicitly in online services or geospatial metadata, in part because authoritative definitions were not created formally. This document describes the purpose of the data categories, provides definitions, and identifies relations among the categories and between the categories and external standards. It is intended to be used by ocean data providers, managers, and users in order to provide a transparent and consistent framework for organizing and describing complex information about marine ecosystems and their connections to humans.

    2015-01-01

    In order to assess the effect of a vascular event on adherence to treatment we examined a total of 68 patients presenting with coronary atherosclerosis. The patients' age varied from 31 to 84 years (mean 57.1±8.7). There were 55 (81.1%) men and 13 (18.9%) women. Drug regimen compliance was evaluated by means of the Morisky-Green Medication Adherence Questionnaire before and after the vascular event. Of the 68 examined patients, 15 (22.1%) had not taken any therapeutic agents before the vascular event occurred, despite existing arterial hypertension. Drug regimen compliance prior to the vascular event was low in 82.4% of cases. The number of patients with coronary atherosclerosis and low compliance to treatment before the vascular event decreased significantly thereafter (p=0.0012). After the vascular event, the number of patients adhering to the doctor's recommendations on medicamentous therapy increases considerably. At the same time, a sufficiently great number of patients [about 30% of patients after endured myocardial infarction (MI) and 18% after transcutaneous coronary intervention (TCI)] still remain in the category of those "having low drug regimen compliance" and, accordingly, have high risk for the development of recurrent vascular events. Endured TCI increases patient compliance more significantly than MI, which requires additional study of a psychological component of the given fact. PMID:26035560

    The objective of the study was to compare the efficacy of three bowel preparation regimens for transabdominal colon ultrasonography. A total of 192 consecutive patients were given one of three regimens (senna, magnesium sulfate or polyethylene glycol electrolyte powder) before ultrasonographic examinations. The cleaning grade (I = emptying; II = filled or filled + empty; III = I or II with some retention; and IV = retention [grades I and II were termed "qualified"]) and cleaning range (A = all seven colon sections were qualified; B = four to six sections were qualified; C = three or less sections were qualified) were evaluated retrospectively. Senna was found more effective than polyethylene glycol in terms of cleaning grade (p < 0.001), qualified rate (p < 0.001) and cleaning range (p = 0.003). Senna was better than magnesium sulfate in cleaning grade (p < 0.001). Our results suggest that senna seems to be the preferred regimen for bowel preparation before transabdominal colonic ultrasonography. PMID:27181688

  13. Pharmacoeconomic consequences of variable patient compliance with prescribed drug regimens.

    PubMed

    Urquhart, J

    1999-03-01

    Variable compliance with prescribed drug regimens is a leading source of variability in drug response. Specifics differ by drug and disease. The role of variable compliance was clearly defined in 2 trials of lipid-lowering agents, cholestyramine and gemfibrozil, in which exceptionally careful measurements of compliance were made, which has not been done in later trials. Economic consequences of variable compliance are estimated by converting dose-dependent changes in absolute risk of incident coronary disease into the unicohort format, which designates how many patients must be treated to prevent, in a given time, a defined 'coronary event'. Two strong influences on the costs of treatment are: (i) the shape of the relation between drug intake and risk reduction; and (ii) the strength of the linkage between intake and prescription refills. The intake-effect relation for cholestyramine is linear, making compliance-neutral the cost to prevent 1 coronary event, provided that refills match intake. If refills exceed intake, treatment costs rise. The intake-effect relation for gemfibrozil is more typically nonlinear, so poorer compliers purchase and take the drug in amounts that have little benefit, increasing the cost to prevent 1 coronary event. If refills run at a higher rate than intake, costs increase still further. A key question for future study is: do policies that encourage timely refills increase compliance enough to offset their potential to waste money in the purchasing of an untaken drug? PMID:10537430

  14. Optimality of the basic colour categories for classification

    2005-01-01

    Categorization of colour has been widely studied as a window into human language and cognition, and quite separately has been used pragmatically in image-database retrieval systems. This suggests the hypothesis that the best category system for pragmatic purposes coincides with human categories (i.e. the basic colours). We have tested this hypothesis by assessing the performance of different category systems in a machine-vision task. The task was the identification of the odd-one-out from triples of images obtained using a web-based image-search service. In each triple, two of the images had been retrieved using the same search term, the other a different term. The terms were simple concrete nouns. The results were as follows: (i) the odd-one-out task can be performed better than chance using colour alone; (ii) basic colour categorization performs better than random systems of categories; (iii) a category system that performs better than the basic colours could not be found; and (iv) it is not just the general layout of the basic colours that is important, but also the detail. We conclude that (i) the results support the plausibility of an explanation for the basic colours as a result of a pressure-to-optimality and (ii) the basic colours are good categories for machine vision image-retrieval systems.

    2016-01-01

    Objective: Helicobacter pylori (H. pylori) eradication remains a challenge with increasing antibiotic resistance. Hybrid therapy has attracted widespread attention because of initial report with good efficacy and safety. However, many issues on hybrid therapy are still unclear such as the eradication efficacy, safety, compliance, influencing factors, correlation with antibiotic resistance, and comparison with other regimens. Therefore, a comprehensive review on the evidence of hybrid therapy for H. pylori infection was conducted. Data Sources: The data used in this review were mainly from PubMed articles published in English up to September 30, 2015, searching by the terms of “Helicobacter pylori” or “H. pylori”, and “hybrid”. Study Selection: Clinical research articles were selected mainly according to their level of relevance to this topic. Results: Totally, 1871 patients of 12 studies received hybrid therapy. The eradication rates were 77.6–97.4% in intention-to-treat and 82.6–99.1% in per-protocol analyses. Compliance was 93.3–100.0%, overall adverse effects rate was 14.5–67.5%, and discontinued medication rate due to adverse effects was 0–6.7%. H. pylori culture and sensitivity test were performed only in 13.3% patients. Pooled analysis showed that the eradication rates with dual clarithromycin and metronidazole susceptible, isolated metronidazole or clarithromycin resistance, and dual clarithromycin and metronidazole resistance were 98.5%, 97.6%, 92.9%, and 80.0%, respectively. Overall, the efficacy, compliance, and safety of hybrid therapy were similar with sequential or concomitant therapy. However, hybrid therapy might be superior to sequential therapy in Asians. Conclusions: Hybrid therapy showed wide differences in the efficacy but consistently good compliance and safety across different regions. Dual clarithromycin and metronidazole resistance were the key factor to efficacy. Hybrid therapy was similar to sequential or concomitant

    Purpose The prelinguistic infant’s babbling repertoire of syllables—the phonological categories that form the basis for early word learning—is noticed by caregivers who interact with infants around them. Prior research on babbling has not explored the caregiver’s role in recognition of early vocal categories as foundations for word learning. In the present work, the authors begin to address this gap. Method The authors explored vocalizations produced by 8 infants at 3 ages (8, 10, and 12 months) in studies illustrating identification of phonological categories through caregiver report, laboratory procedures simulating the caregiver’s natural mode of listening, and the more traditional laboratory approach (phonetic transcription). Results Caregivers reported small repertoires of syllables for their infants. Repertoires of similar size and phonetic content were discerned in the laboratory by judges who simulated the caregiver’s natural mode of listening. However, phonetic transcription with repeated listening to infant recordings yielded repertoire sizes that vastly exceeded those reported by caregivers and naturalistic listeners. Conclusions The results suggest that caregiver report and naturalistic listening by laboratory staff can provide a new way to explore key characteristics of early infant vocal categories, a way that may provide insight into later speech and language development.

    Improvement in tuberculosis treatment regimens requires selection of antibiotics and dosing schedules from a large design space of possibilities. Incomplete knowledge of antibiotic and host immune dynamics in tuberculosis granulomas impacts clinical trial design and success, and variations among clinical trials hamper side-by-side comparison of regimens. Our objective is to systematically evaluate the efficacy of isoniazid and rifampin regimens, and identify modifications to these antibiotics that improve treatment outcomes. We pair a spatio-temporal computational model of host immunity with pharmacokinetic and pharmacodynamic data on isoniazid and rifampin. The model is calibrated to plasma pharmacokinetic and granuloma bacterial load data frommore » non-human primate models of tuberculosis and to tissue and granuloma measurements of isoniazid and rifampin in rabbit granulomas. We predict the efficacy of regimens containing different doses and frequencies of isoniazid and rifampin. We predict impacts of pharmacokinetic/pharmacodynamic modifications on antibiotic efficacy. We demonstrate that suboptimal antibiotic concentrations within granulomas lead to poor performance of intermittent regimens compared to daily regimens. Improvements from dose and frequency changes are limited by inherent antibiotic properties, and we propose that changes in intracellular accumulation ratios and antimicrobial activity would lead to the most significant improvements in treatment outcomes. Results suggest that an increased risk of drug resistance in fully intermittent as compared to daily regimens arises from higher bacterial population levels early during treatment. In conclusion, our systems pharmacology approach complements efforts to accelerate tuberculosis therapeutic development.« less

    A wide choice of drug combinations is available to clinicians for immunosuppression regimens for their kidney transplant patients. Although many protocols have minimized early graft loss, the optimal long-term regimen is unknown. Recent studies clearly showed that cardiovascular death is now the leading cause of graft loss. Strategies must be developed that address this risk while keeping immunologic events low. Transplant physicians have focused on exploring regimens that minimize or avoid the use of corticosteroids. Studies also have started to explore protocols that minimize calcineurin inhibitor therapy. PMID:16567240

    Standard salvage chemotherapy for refractory or relapsed malignant lymphoma has not been defined. The efficacy and feasibility of the ACES regimen, consisting of carboplatin at 100 mg/m(2) on day 1 to 4, etoposide at 80 mg/m(2) on day 1 to 4, high-dose Ara-C at 2 g/m(2) on day 5 and methylprednisolone at 500 mg/day for 5 days, for refractory or relapsed lymphoma were retrospectively reviewed in comparison with the ESHAP regimen. The subjects were 29 patients, including 7 aggressive follicular lymphomas, 16 large B cell lymphomas and 6 Hodgkin lymphomas. Characteristics of patients with ESHAP (19 cases) and the ACES (10 cases) group were as follows: male/female ratio, 10/9 and 3/7; median age, 49 (range, 31-72) and 54 (22-65); and initial clinical stage (I and II / III / IV), 5/8/6 and 1/1/8, respectively. Among the 29 patients, complete response was achieved in 68% (13/19) in ESHAP and 40% (4/10) in ACES.Progression-free survival and overall survival were 31.3% and 34.3%, respectively. Hematological toxicity was not significantly different between the two groups, and renal toxicity was significantly higher in ESHAP (52%) than ACES (0%). We concluded that the ACES regimen had a possibility of effective consolidation therapy for the elderly aiming to undergo autologous stem cell transplantation. PMID:17940378

    Feeding states may affect the performance of colonic prodrugs. The aim is to investigate the influence of feeding regimen in Wistar rats on: (i) distribution and pH contents along the gut and (ii) metabolism of two colonic prodrugs, diclofenac-β-cyclodextrin and a commercially available control, sulfasalazine, within the caecal and colonic contents. Male Wistar rats were subject to four different feeding regimens, the gut contents characterized (mass and pH) and the metabolism of prodrugs investigated. The feeding regimen affects gut contents (mass and pH), more specifically in the stomach and lower intestine, and affects the rate of metabolism of diclofenac-β-cyclodextrin, but not that of sulfasalazine. The latter's degradation is much faster than that of diclofenac-β-cyclodextrin while the metabolism of both prodrugs is faster in colonic (versus caecal) contents. Fasting results in most rapid degradation of diclofenac-β-cyclodextrin, possibly due to lack of competition (absence of food) for microbial enzymatic activity. PMID:25129806

    A theoretical framework within neuroscience distinguishes humans' implicit and explicit systems for category learning. We used a perceptual-categorization paradigm to ask whether nonhumans share elements of these systems. Participants learned categories that foster implicit or explicit categorization in humans, because they had a multidimensional, information-integration (II) solution or a unidimensional, rule-based (RB) solution. Then humans and macaques generalized their category knowledge to new, untested regions of the stimulus space. II generalization was impaired, suggesting that II category learning is conditioned and constrained by stimulus generalization to its original, trained stimulus contexts. RB generalization was nearly seamless, suggesting that RB category knowledge in humans and monkeys has properties that grant it some independence from the original, trained stimulus contexts. These findings raise the questions of (a) how closely macaques' dimensional categorization verges on humans' explicit/declarative categorization, and (b) how far macaques' dimensional categorization has advanced beyond that in other vertebrate species.

  15. New regimens for intravenous acetylcysteine, where are we now?

    Bateman, D Nicholas; Dear, James W; Thomas, Simon H L

    2016-01-01

    Acetylcysteine has been used as a treatment for paracetamol overdose as a 20.25- or 21-h infusion for nearly 40 years. These regimens give 50% of the dose in the first 15 min or 1 h, and are associated with high rates of adverse reactions. A randomised controlled trial has demonstrated that a shorter (12 h) and simpler (two infusions) acetylcysteine regimen using a slower initial infusion rate produces lower rates of adverse events than the original 20.25-h regimen. However, this study was not sufficiently large to show therapeutic equivalence as a hepatoprotective therapy in paracetamol overdose. Two further studies are now reported, which also suggest lower rates of adverse reactions with lower initial rates of acetylcysteine administration. These modified regimens can now be accepted as better tolerated, but it is unlikely that a randomised study of sufficient size to demonstrate non-inferiority of any novel regimen would ever be funded. Against this background we suggest what can be done to establish the efficacy of these less toxic and potentially shorter alternative acetylcysteine regimens and to establish them into routine clinical use.

    Rationale: For treatment of multidrug-resistant tuberculosis, World Health Organization (WHO) guidelines recommend four likely effective drugs plus pyrazinamide (PZA), irrespective of the likely effectiveness of PZA in an individual patient. Whether this regimen should be supplemented in the absence of likely PZA effectiveness is an open question. Objectives: The objectives of this study were to examine (1) whether individuals receiving four likely effective drugs (based on documented susceptibility or no prior exposure) experienced higher mortality during the intensive phase of treatment than those receiving five likely effective drugs and (2) whether the WHO-recommended regimen (four likely effective drugs plus PZA) may be compromised in individuals in whom PZA is not likely effective. Methods: Among 668 patients, we compared the hazard of death across regimen groups characterized by the number of likely effective drugs and whether pyrazinamide was one of the likely effective drugs. Measurements and Main Results: Relative to five likely effective drugs, regimens of four likely effective drugs and the WHO-recommended regimen used in individuals in whom PZA was not likely effective were associated with higher mortality rates (respectively, adjusted hazard ratio [HR], 2.87; 95% confidence interval [CI], 1.35–6.09 and adjusted HR, 2.76; 95% CI, 0.92–8.27). The mortality rate for a regimen of five likely effective drugs with likely effective PZA was similar to that for the regimen of five likely effective drugs without PZA (HR, 1.00; 95% CI, 0.12–8.00). Conclusions: Mortality may be reduced by the inclusion of five likely effective drugs, including an injectable, during the intensive phase of treatment. If PZA is unlikely to be effective in an individual patient, these results suggest adding a different, likely effective drug. PMID:25664920

    Previous research suggests that high functioning (HF) children with autism spectrum disorder (ASD) sometimes have problems learning categories, but often appear to perform normally in categorization tasks. The deficits that individuals with ASD show when learning categories have been attributed to executive dysfunction, general deficits in implicit learning, atypical cognitive strategies, or abnormal perceptual biases and abilities. Several of these psychological explanations for category learning deficits have been associated with neural abnormalities such as cortical underconnectivity. The present study evaluated how well existing neurally based theories account for atypical perceptual category learning shown by HF children with ASD across multiple category learning tasks involving novel, abstract shapes. Consistent with earlier results, children's performances revealed two distinct patterns of learning and generalization associated with ASD: one was indistinguishable from performance in typically developing children; the other revealed dramatic impairments. These two patterns were evident regardless of training regimen or stimulus set. Surprisingly, some children with ASD showed both patterns. Simulations of perceptual category learning could account for the two observed patterns in terms of differences in neural plasticity. However, no current psychological or neural theory adequately explains why a child with ASD might show such large fluctuations in category learning ability across training conditions or stimulus sets.

    Apple (Malus × domestica Borkh.) is one of the most widely cultivated tree crops, and fruit storability is vital to the profitability of the apple fruit industry. Fruit of many apple cultivars can be stored for an extended period due to the introduction of advanced storage technologies, such as controlled atmosphere (CA) and 1-methylcyclopropane (1-MCP). However, CA storage can cause external CO2 injury for some apple cultivars. The molecular changes associated with the development of CO2 injury are not well elucidated. In this study, the global transcriptional regulations were investigated under different storage conditions and during development of CO2 injury symptoms on ‘Golden Delicious’ fruit. Fruit peel tissues under three different storage regimens, regular cold atmosphere, CA and CA storage and 1-MCP application were sampled at four storage durations over a 12-week period. Fruit physiological changes were affected differently under these storage regimens, and CO2 injury symptoms were detectable 2 weeks after CA storage. Identification of the differentially expressed genes and a gene ontology enrichment analysis revealed the specific transcriptome changes associated with each storage regimen. Overall, a profound transcriptome change was associated with CA storage regimen as indicated by the large number of differentially expressed genes. The lighter symptom was accompanied by reduced transcriptome changes under the CA storage and 1-MCP application regimen. Furthermore, the higher enrichment levels in the functional categories of oxidative stress response, glycolysis and protein post-translational modification were only associated with CA storage regime; therefore, these processes potentially contribute to the development of external CO2 injury or its symptom in apple.

    Objective The purpose of this study was to investigate compliance of long-term xylitol and sorbitol chewing gum regimens in adult women participating in a double-blind randomized controlled clinical trial. Design The participants included 122 mothers (age range: 16–35 years) residing in the city of Bauru, São Paulo, Brazil. Compliance with the xylitol and sorbitol chewing gum regimens was assessed by weighing, with a precision balance, all used gums returned in zip-lock bags during the study period of 33 months. The total number of returned bags in both chewing gum groups was computed and the differences between groups were determined by one-way ANOVA. Compliance was further categorized into excellent, good, fair or poor based on the distribution of the combined data for both groups by quartiles. These distributions for the xylitol and sorbitol groups were subjected to chi-square analysis. Results Compliance was always superior for the xylitol group in all categories. These distributions were, however, not significantly different in statistical terms. Average compliance in the xylitol chewing gum group was significantly higher when compared to the sorbitol chewing gum group (p=0.0481). Conclusions The results suggest that compliance, and possibly acceptance in this population, was superior for xylitol chewing gum than for sorbitol chewing gum. PMID:22241940

    Objectives The aim of the study was to describe adherence to health regimens and the factors associated with it among adult frequent attenders (FAs). Design This was a cross-sectional study. The study sample consisted of 462 healthcare FAs in 7 municipal health centres in northern Finland. An FA is a person who has had 8 or more outpatient visits to a GP (in a health centre) or 4 or more outpatient visits to a university hospital during 1 year. The main outcome was self-reported adherence to health regimens. Results Of the FAs, 82% adhered well to their health regimens. Carrying out self-care, medical care and feeling responsible for self-care were the most significant predictors to good adherence in all models. No significant differences in adherence were found in male and female subjects, age groups or educational levels. Support from healthcare providers and support from relatives were not significant predictors of good adherence. Conclusion FAs in Finland adhere well to health regimens and exceptionally well to medication. Variables that predict the best adherence of FAs to health regimens are carrying out self-care, receiving medical care and feeling responsible for self-care. PMID:26996780

  3. Lexically guided retuning of visual phonetic categories.

    2013-07-01

    Listeners retune the boundaries between phonetic categories to adjust to individual speakers' productions. Lexical information, for example, indicates what an unusual sound is supposed to be, and boundary retuning then enables the speaker's sound to be included in the appropriate auditory phonetic category. In this study, it was investigated whether lexical knowledge that is known to guide the retuning of auditory phonetic categories, can also retune visual phonetic categories. In Experiment 1, exposure to a visual idiosyncrasy in ambiguous audiovisually presented target words in a lexical decision task indeed resulted in retuning of the visual category boundary based on the disambiguating lexical context. In Experiment 2 it was tested whether lexical information retunes visual categories directly, or indirectly through the generalization from retuned auditory phonetic categories. Here, participants were exposed to auditory-only versions of the same ambiguous target words as in Experiment 1. Auditory phonetic categories were retuned by lexical knowledge, but no shifts were observed for the visual phonetic categories. Lexical knowledge can therefore guide retuning of visual phonetic categories, but lexically guided retuning of auditory phonetic categories is not generalized to visual categories. Rather, listeners adjust auditory and visual phonetic categories to talker idiosyncrasies separately. PMID:23862831

    A programmable calculator procedure for the determination of dosage regimens to achieve desired steady state concentrations is described. The dosage regimen prediction is based on data from the literature on pharmacokinetic parameters of drugs and correction factors specific for the patient's condition, such as renal failure, geriatric patient and congestive heart failure. The program is designed to generate dosage regimens based on desired steady state trough level, desired steady state peak level, desired mean steady state level, or to fluctuate between desired steady state peak and trough levels. The program can be used for I.V. and extravascular route of administration. A detailed program description and user instructions are presented and illustrated by three examples. PMID:3840551

    The level of pain following the extraction of impacted third molars was evaluated in 75 patients. Participants were administered acetaminophen 1,000 mg or a placebo before surgery. After surgery, acetaminophen 650 mg was administered either at fixed intervals or as needed to relieve pain. When acetaminophen was administered before surgery, the onset of peak pain was delayed and patient discomfort was decreased 3, 4, and 5 hours after surgery. Patients following the fixed interval regimen after surgery experienced more pain overall and requested the backup narcotic analgesic more frequently. Of the regimens tested, patients preferred the regimen of acetaminophen 1,000 mg administered before surgery with acetaminophen administered as needed for pain after surgery. PMID:3465787

    This study aims to determine the maximum tolerated dose (MTD) of clofarabine combined with the EORTC-GIMEMA 3 + 10 induction regimen (idarubicin + cytosine arabinoside) in adults with untreated acute myelogenous leukemia or high-risk myelodysplastic syndrome. In this phase I trial, 25 patients (median age 56 years) received 5 days of clofarabine as 1-h infusion (arm A) or push injection (arm B) at the dose level of 5 × 10 or 5 × 15 mg/m(2)/day in an algorithmic dose escalation 3 + 3 design. A consolidation course (intermediate dose cytosine arabinoside, idarubicin) was planned for patients in complete remission (CR). Primary endpoint was safety and tolerance as measured by dose limiting toxicity (DLT); secondary endpoints were response rate, other grade III/IV toxicities, and hematological recovery after induction and consolidation. Five DLTs were observed (in arm A: one DLT at 10 mg/m(2)/day, three at 15 mg/m(2)/day; in arm B: one DLT at 15 mg/m(2)/day). Three patients receiving 15 mg/m(2)/day were withdrawn due to adverse events not classified as DLT. Prolonged hypoplasia was observed in five patients. CR + complete remission with incomplete recovery were achieved in 21 patients (11/12 (92 %) receiving clofarabine 10 mg/m(2)/day; 10/13 (77 %) receiving clofarabine 15 mg/m(2)/day). Clofarabine, 5 × 10 mg/m(2)/day, resulted in one DLT and no early treatment withdrawals. MTD of clofarabine combined with cytosine arabinoside and idarubicin is 5 × 10 mg/m(2)/day. PMID:24682421

    Background There is considerable variability in the manner in which prescriptions are written by physicians and transcribed by pharmacists, resulting in patient misunderstanding of label instructions. A ‘universal medication schedule’ (UMS) was recently proposed for standardizing prescribing practices to four daily time intervals thereby helping patients simplify and safely use their medicine. We investigated whether patients consolidate their medications, or if there is evidence of unnecessary regimen complexity that would support standardization. Methods Structured interviews were conducted with 464 adults ages 55–74 who were receiving care at either an academic general medicine practice or one of three federally qualified health centers in Chicago, Illinois. Subjects were given a hypothetical, seven-drug medication regimen and asked to demonstrate how and when they would take all of the medicine in a 24-hour period. The regimen could be consolidated into four dosing episodes per day. The primary outcome was the number of times per day individuals would take medicine. Root causes for patients complicating the regimen (> four times a day) were examined. Results Participants on average identified six times in 24 hours to take the seven drugs (SD=1.8; range 3 to 14). One third (29.3%) found seven or more times per day to take their medicine, while only 14.9% organized the regimen into four or fewer times a day. In multivariable analysis, low literacy was an independent predictor of more times per day for dosing out the regimen (β=0.67; 95% Confidence Interval 0.12 to 1.22, p=0.018). Instructions for two of the drugs were identical, yet 31% of patients did not dose these medicines at the same time. Another set of drugs had similar instructions with the primary exception of one having the added instruction to take “with food and water”. Half (49.5%) of participants dosed these medicines at different times. When medicines had variable expressions of the same

    The 'soak and smear' regimen is a highly effective method for localised topical therapy employed by dermatologists for widespread inflammatory skin conditions. The regimen involves application of topical medication under occlusion after soaking in water. Complications from this treatment method are rare. We present a case of multiple, generalised methicillin-resistant Staphylococcus aureus (MRSA)-positive furuncles arising in a patient as an unexpected consequence of therapy. The case highlights an unanticipated risk of a commonly employed treatment amid an epidemic of MRSA in the community. PMID:25694635

    Background: The present study was aimed to evaluate the efficacy and safety of at least three cycles of Bevacizumab in combination with chemotherapy regimens, FOLFIRI or FOLFOX to treat liver metastatic colorectal cancer and improved response rates in these patients. Materials and Methods: In this non-randomized clinical trial, 38 patients were enrolled and followed for 12-weeks period of chemotherapy. Fifteen patients under treated with FOLOFX (Group I), 15 patients under treated with FOLOFIRI (Group II), 4 patients under treated with FOLOFX + Bevacizumab (Group III), and 34 patients under treated with FOLOFIRI + Bevacizumab (Group IV). Response to treatment was assessed in all patients as main endpoint. Patients in groups I and II, who did not response to treatment after 12 weeks of chemotherapy, were followed by groups III and IV regimens, respectively, for 12 weeks. Results: Overall response rate was 35% (19 of 54), and complete response (CR), partial response (PR), progressive disease (PD), and stable disease (SD) rates in all patients were 18%, 17%, 35%, and 30%. PR, SD, and PD were different among groups, but no statistical significance was noted among groups (P-value >0.05). No patient achieved a CR in groups III and IV, although CR was observed in 4 patients (27%) and 6 patients (40%) in groups I and II, respectively. The rare of CR was statistically significant among studied groups (P-value = 0.013). Conclusion: Results showed that adding Bevacizumab to chemotherapy regimens, in patients who did not response to FOLFIRI or FOLFOX regimen, did not increase CR in these patients. PMID:26962512

    One of the purposes of the research program referred to as "systematic biogeography" is the use of species distributions to identify regions and reconstruct biotic area relationships. The reverse, i.e. to group species according to the areas that they live in, leads to the recognition of chorological categories. Biogeographers, working under these two different approaches, have proposed several terms to refer to groups of species that have similar distributions, such as "element", "chorotype" and "component". A historical reconstruction, including semantic observations and philosophical implications, shows that these terms have been used in a variety of senses. The word "component" should not be used in biogeography. The word "element" has been used to identify both a group of species defined according to the biogeographic areas they occupy and a group of species with an assumed shared biogeographic history. It is especially because of the influence of the dispersalist paradigm, which dominated evolutionary thought until the mid-twentieth century, that the second definition has been frequently adopted. The term "element" is therefore ambiguous and its use should always be associated with an explicit definition. The word "chorotype" should be used to define groups of species with similar ranges when no causal assumption is made. The concept of "chorotype," finally, should not be confounded with other concepts such as distributional pattern, cenocron, horofauna, biota, endemic area, area of endemism, biotic element, and generalized track, which are also discussed in this paper.

    Objective To determine whether seniors consolidate their home medications or if there is evidence of unnecessary regimen complexity. Methods Face-to-face interviews were conducted with 200 community-dwelling seniors > 70 years in their homes. Subjects demonstrated how they took their medications in a typical day and the number of times a day patients would take medications was calculated. A pharmacist and physician blinded to patient characteristics examined medication regimens and determined the fewest number of times a day they could be taken by subjects. Results Home medication regimens could be simplified for 85 (42.5%) subjects. Of those subjects not optimally consolidating their medications, 53 (26.5%) could have had the number of times a day medications were taken reduced by one time per day; 32 (16.0%) reduced by two times or more. The three most common causes of overcomplexity were (1) misunderstanding medication instructions, (2) concern over drug absorption (i.e. before meals), and (3) perceived drug-drug interactions. Conclusion Almost half of seniors had medication regimens that were unnecessarily complicated and could be simplified. This lack of consolidation potentially impedes medication adherence. Practice Implications Health care providers should ask patients to explicitly detail when medication consumption occurs in the home. PMID:24793007

    Recently, PK/PD (pharmacokinetics/pharmacodynamics) analysis for the antimicrobial dosage method became one of the popular categories in chemotherapy and infectious disease societies world wide. Carbapenems are often used for empiric therapy because of its broad-spectrum and activities against microorganisms. PK/PD analysis is well studied in some antibiotics including carbapenems and it is necessary also from the point of view of prevention for emergence of resistant strains. We report the result of the analysis for the effective dosage regimens of meropenem, biapenem and doripenem against Pseudomonas aeruginosa infection based on PK/PD theory with the MIC distributions against the strains isolated from the patients blood at Keio University in 2004 and 2006. The highest target attainment rate for the free drug 40% time above the MIC (40%T > or = MIC) in traditional infusion with the MIC distribution against P. aeruginosa isolated from the patients blood at Keio University Hospital in 2004 was as follows: 90.89% in 500 mg every 6 hours regimen for meropenem, 83.25% in 300 mg every 6 hours regimen for biapenem, 81.73% in 250 mg every 6 hours regimen for doripenem in the approved maximum daily dose for each agent. The highest target attainment rate for the free drug 40%T > or = MIC in prolonged infusion with the MIC distribution against P. aeruginosa isolated from the patients blood at Keio University Hospital in 2004 was as follows: 100% in 500 mg every 6 hours regimen for meropenem, 83.97% in 300 mg every 8 hours regimen for biapenem, 99.98% in 500 mg every 8 hours regimen for doripenem in the maximum daily dose for each agents. The highest target attainment rate for the free drug 40%T > or = MIC in traditional infusion with the MIC distribution against P. aeruginosa isolated from the patients blood at Keio University Hospital in 2006 was as follows: 80.57% in 500 mg dose in every 6 hours regimen for meropenem, 56.70% in 300 mg every 6 hours regimen for biapenem

  17. The integration of oral capecitabine into chemoradiation regimens for locally advanced rectal cancer: how successful have we been?

    The aim was to review available literature on capecitabine-based chemoradiation regimens for the preoperative treatment of patients with locally advanced rectal cancer (LARC) and determine efficacy and safety data for capecitabine in this setting. Medical literature databases (Pubmed, Medline) and abstracts/posters presented at recent scientific congresses (ASCO, ASTRO, ESTRO and ECCO) were screened and critically analysed to identify relevant data. A number of phase I/II studies have demonstrated that capecitabine is effective and well tolerated in combination with preoperative radiotherapy in patients with LARC. Phase III studies are ongoing. Continuous oral administration of capecitabine (825 mg/m(2) twice daily for 7 days/week) is an effective regimen and has similar tolerability to the less dose-intensive intermittent regimens of capecitabine given 5 days/week followed by 2 day's rest or 14 days followed by 7 day's rest as used in systemic chemotherapy for patients with colorectal or breast cancer. Capecitabine chemoradiation is associated with a relatively low rate of grade 3/4 adverse events. Capecitabine simplifies chemoradiation and provides a convenient treatment option for both patients and health care professionals. Combining capecitabine with cytotoxic agents such as oxaliplatin and irinotecan has the potential to further improve antitumour efficacy in patients receiving preoperative chemoradiation. Data from phase I/II single-agent and combination capecitabine chemoradiation studies provide a clear rationale for replacing infusional 5-FU with oral capecitabine as part of chemoradiation for patients with LARC.

  20. Aggressive Regimens for Multidrug-Resistant Tuberculosis Reduce Recurrence

    Background. Recurrent tuberculosis disease occurs within 2 years in as few as 1% and as many as 29% of individuals successfully treated for multidrug-resistant (MDR) tuberculosis. A better understanding of treatment-related factors associated with an elevated risk of recurrent tuberculosis after cure is urgently needed to optimize MDR tuberculosis therapy. Methods. We conducted a retrospective cohort study among adults successfully treated for MDR tuberculosis in Peru. We used multivariable Cox proportional hazards regression analysis to examine whether receipt of an aggressive MDR tuberculosis regimen for ≥18 months following sputum conversion from positive to negative was associated with a reduced rate of recurrent tuberculosis. Results. Among 402 patients, the median duration of follow-up was 40.5 months (interquartile range, 21.2–53.4). Receipt of an aggressive MDR tuberculosis regimen for ≥18 months following sputum conversion was associated with a lower risk of recurrent tuberculosis (hazard ratio, 0.40 [95% confidence interval, 0.17–0.96]; P = .04). A baseline diagnosis of diabetes mellitus also predicted recurrent tuberculosis (hazard ratio, 10.47 [95% confidence interval, 2.17–50.60]; P = .004). Conclusions. Individuals who received an aggressive MDR tuberculosis regimen for ≥18 months following sputum conversion experienced a lower rate of recurrence after cure. Efforts to ensure that an aggressive regimen is accessible to all patients with MDR tuberculosis, such as minimization of sequential ineffective regimens, expanded drug access, and development of new MDR tuberculosis compounds, are critical to reducing tuberculosis recurrence in this population. Patients with diabetes mellitus should be carefully managed during initial treatment and followed closely for recurrent disease. PMID:23223591

  1. Conceptual influences on category-based induction

    2013-01-01

    One important function of categories is to permit rich inductive inferences. Prior work shows that children use category labels to guide their inductive inferences. However, there are competing theories to explain this phenomenon, differing in the roles attributed to conceptual information versus perceptual similarity. Seven experiments with 4- to 5-year-old children and adults (N = 344) test these theories by teaching categories for which category membership and perceptual similarity are in conflict, and varying the conceptual basis of the novel categories. Results indicate that for non-natural kind categories that have little conceptual coherence, children make inferences based on perceptual similarity, whereas adults make inferences based on category membership. In contrast, for basic- and ontological-level categories that have a principled conceptual basis, children and adults alike make use of category membership more than perceptual similarity as the basis of their inferences. These findings provide evidence in favor of the role of conceptual information in preschoolers’ inferences, and further demonstrate that labeled categories are not all equivalent; they differ in their inductive potential.

    2015-01-01

    Behavioral, neuropsychological, and neuroimaging evidence has suggested that categories can often be learned via either an explicit rule-based (RB) mechanism critically dependent on medial temporal and prefrontal brain regions, or via an implicit information-integration (II) mechanism relying on the basal ganglia. In this study, participants viewed sine-wave gratings (Gabor patches) that varied on two dimensions and learned to categorize them via trial-by-trial feedback. Two different stimulus distributions were used; one was intended to encourage an explicit RB process and the other an implicit II process. We monitored brain activity with scalp electroencephalography (EEG) while each participant: (1) passively observed stimuli represented of both distributions; (2) categorized stimuli from one distribution, and, 1 week later; (3) categorized stimuli from the other distribution. Categorization accuracy was similar for the two distributions. Subtractions of Event-Related Potentials (ERPs) for correct and incorrect trials were used to identify neural differences in RB and II categorization processes. We identified an occipital brain potential that was differentially modulated by categorization condition accuracy at an early latency (150–250 ms), likely reflecting the degree of holistic processing. A stimulus-locked Late Positive Complex (LPC) associated with explicit memory updating was modulated by accuracy in the RB, but not the II task. Likewise, a feedback-locked P300 ERP associated with expectancy was correlated with performance only in the RB, but not the II condition. These results provide additional evidence for distinct brain mechanisms supporting RB vs. implicit II category learning and use. PMID:26217210

    multivariable analysis, receiving an average of at least six potentially effective drugs (defined as drugs without a DST result indicating resistance) per day was associated with a 36% greater likelihood of sputum culture conversion than receiving an average of at least five but fewer than six potentially effective drugs per day (adjusted hazard ratio [aHR] 1.36, 95% CI 1.09–1.69). Inclusion of pyrazinamide (aHR 2.00, 95% CI 1.65–2.41) or more drugs to which baseline DST indicated susceptibility (aHR 1.65, 95% CI 1.48–1.84, per drug) in regimens was associated with greater increases in the likelihood of sputum culture conversion than including more drugs to which baseline DST indicated resistance (aHR 1.33, 95% CI 1.18–1.51, per drug). Including in the regimen more drugs for which DST was not performed was beneficial only if a minimum of three effective drugs was present in the regimen (aHR 1.39, 95% CI 1.09–1.76, per drug when three effective drugs present in regimen). The main limitation of this analysis is that it is based on observational data, not a randomized trial, and drug regimens varied across sites. However, PETTS was a uniquely large and rigorous observational study in terms of both the number of patients enrolled and the standardization of laboratory testing. Other limitations include the assumption of equivalent efficacy across drugs in a category, incomplete data on adherence, and the fact that the analysis considers only initial sputum culture conversion, not reversion or long-term relapse. Conclusions MDR TB regimens including more potentially effective drugs than the minimum of five currently recommended by WHO may encourage improved response to treatment in patients with MDR TB. Rapid access to high-quality DST results could facilitate the design of more effective individualized regimens. Randomized controlled trials are necessary to confirm whether individualized regimens with more than five drugs can indeed achieve better cure rates than current

    Abstract Patients’ experience during treatment may affect treatment adherence. Our aim was to assess the impact of patient-reported outcomes (PROs) on adherence to different anti-hepatitis C virus (HCV) regimens. Clinical, demographic, and PRO data (short form-36 [SF-36], chronic liver disease questionnaire-hepatitis C version [CLDQ-HCV], functional assessment of chronic illness therapy-fatigue [FACIT-F], work productivity and activity impairment: specific health problem [WPAI:SHP]) from 13 multinational clinical trials of anti-HCV treatment were available. Treatment adherence was defined as >80% of prescribed doses taken. Included were 4825 HCV patients. Regimens were grouped into: interferon- and ribavirin (RBV)-containing (±sofosbuvir [SOF]), interferon-free RBV-containing (RBV + SOF ± ledipasvir [LDV]), and interferon-free RBV-free (LDV/SOF). The adherence to these regimens were 77.6%, 84.3%, and 96.2%, respectively (P < 0.0001). Nonadherent patients were more likely to be unemployed and to have a greater PRO impairment at baseline (up to −5.3% lower PRO scores, P < 0.0001). During treatment with interferon- or RBV-based regimens, nonadherent patients experienced lower PROs and had larger decrements from their baseline PRO scores. In contrast, there were no significant declines in PRO scores (all P > 0.05) for the small number of patients who were nonadherent to LDV/SOF. In multivariate analysis, being treatment-naive, longer treatment duration, and receiving an interferon- or RBV-containing regimen were associated with a lower likelihood of adherence (all P < 0.003). Better baseline and on-treatment PRO scores were associated with a higher likelihood of adherence to interferon and RBV. The use of interferon and/or RBV, longer duration of treatment, and lower baseline and on-treatment PRO scores were linked to a decreased likelihood of being adherent to interferon + RBV-containing or interferon-free RBV-containing antiviral

    Roseobacter litoralis OCh149 is a type strain of aerobic anoxygenic phototrophic bacteria in marine Roseobacter clade. Its full genome has been sequenced; however, proteomic research, which will give deeper insights into the environmental stimuli on gene expression networks, has yet to be performed. In the present study, a proteomic approach was employed to analyze the status of R. litoralis OCh149 in carbon starvation during the stationary phase and its responses to a dark/light regimen (12 h:12 h) in both exponential and stationary phases. LC-MS/MS-based analysis of highly abundant proteins under carbon starvation revealed that proteins involved in transport, the transcription/translation process and carbohydrate metabolism were the major functional categories, while poly-β-hydroxyalkanoate (PHA), previously accumulated in cells, was remobilized after stress. Glucose, as the sole carbon source in the defined medium, was broken down by Entner-Doudoroff and reductive pentose phosphate (PP) pathways. Carbohydrate catabolism-related proteins were down-regulated under light regardless of the growth phase, probably due to inhibition of respiration by light. In contrast, responses of amino acid metabolisms to light regimen varied among different proteins during growth phases depending on cellular requirements for proliferation, growth or survival. Fluorescence induction and relaxation measurements suggested that functional absorption cross-sections of the photosynthetic complexes decreased during the dark period and always recovered to about the previous level during the light period. Although the photosynthetic genes in R. litoralis OCh149 are located on the plasmid, these data indicate the regulatory mechanism of photoheterotroph metabolism by both carbon and light availability.

    A dynamic treatment regimen incorporates both accrued information and long-term effects of treatment from specially designed clinical trials. As these trials become more and more popular in conjunction with longitudinal data from clinical studies, the development of statistical inference for optimal dynamic treatment regimens is a high priority. In this paper, we propose a new machine learning framework called penalized Q-learning, under which valid statistical inference is established. We also propose a new statistical procedure: individual selection and corresponding methods for incorporating individual selection within penalized Q-learning. Extensive numerical studies are presented which compare the proposed methods with existing methods, under a variety of scenarios, and demonstrate that the proposed approach is both inferentially and computationally superior. It is illustrated with a depression clinical trial study. PMID:26257504

However, despite our expectation, thrombocytopenia was seen after 2 years follow-up. PMID:25110635

  9. Short course antiretroviral regimens to reduce maternal transmission of HIV.

    Wilkinson, D; Karim, S S; Coovadia, H M

    1999-02-20

    The ACTG076 trial showed that a complex and expensive antiretroviral regimen reduced mother-to-child HIV transmission by 67%. A more recent Bangkok perinatal HIV study found that oral zidovudine (AZT) given during late pregnancy and labor to non-breast-feeding women reduced the rate of vertical HIV transmission by 51%. These latter findings are particularly interesting to countries unable to afford the more expensive and complex 076 regimen. The reaction to the results of the Bangkok trial may, however, threaten the health of Africa's poorest women and children. Within days of the release of the Thai data, investigators studying other regimens closed recruitment to the placebo arms of their trials, and it has recently become clear that the National Institutes for Health will probably fund no more placebo-controlled trials of interventions designed to reduce maternal HIV transmission. The use of antiretroviral drugs in Africa is unlikely to ever significantly reduce maternal HIV transmission and the incidence of pediatric AIDS. While most of Africa's women have no option to breast-feed, breast-feeding is responsible for one-third of maternal HIV transmission cases. The results of the Thai trials only partially address the needs of African women, for the nutritional, immunological, and birth spacing benefits of breast-feeding should be retained if possible, and formula feeding may stigmatize HIV-infected mothers. The short-course regimen is still expensive to developing countries, and the implementation of a costly, vertical program may also draw financial and human resources from other programs. Placebo-controlled trials to develop simple, cheap, and effective potentially non-drug interventions against vertical HIV transmission should be encouraged in settings in which antiretroviral drugs and formula feeding cannot be safely delivered.

    The advent of combination antiretroviral drug regimens has transformed HIV infection from a fatal illness into a manageable chronic condition. All patients with HIV infection should be considered for antiretroviral therapy, regardless of CD4 count or HIV viral load, for individual benefit and to prevent HIV transmission. Antiretroviral drugs affect HIV in several ways: entry inhibitors block HIV entry into CD4 T cells; nucleotide and nucleoside reverse transcriptase inhibitors prevent reverse transcription from RNA to DNA via chain-terminating proteins; nonnucleoside reverse transcriptase inhibitors prevent reverse transcription through enzymatic inhibition; integrase strand transfer inhibitors block integration of viral DNA into cellular DNA; protease inhibitors block maturation and production of the virus. Current guidelines recommend six combination regimens for initial therapy. Five are based on tenofovir and emtricitabine; the other uses abacavir and lamivudine. Five include integrase strand transfer inhibitors. HIV specialists should assist with treating patients with complicated HIV infection, including patients with treatment-resistant HIV infection, coinfection with hepatitis B or C virus, pregnancy, childhood infections, severe opportunistic infections, complex drug interactions, significant drug toxicity, or comorbidities. Family physicians can treat most patients with HIV infection effectively by choosing appropriate treatment regimens, monitoring patients closely, and retaining patients in care. PMID:27092564

    The optimal conditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in acute leukemia remains undefined. We evaluated the outcomes in 30 patients with acute leukemia who underwent allo-HSCT from human leukocyte antigen-matched donors after conditioning with busulfan and fludarabine (BuFlu). The regimen comprised injection of busulfan 3.2 mg/kg daily on 4 consecutive days and fludarabine 30 mg/m2 daily for 4 doses. All 30 patients achieved hematopoiesis reconstitution with full donor chimerism confirmed by short tandem repeat DNA analysis. The most common regimen-related toxicity was mucositis (86.7%), followed by cytomegalovirus infection (80%). Serious regimen-related toxicities were rare. Acute graft vs. host disease (aGVHD) was detected in 46.7% of the patients; 33.4% had grade I–II aGVHD and 13.3% had grade III–IV aGVHD. Chronic GVHD (cGVHD) was noted in 20% of the patients. The overall survival and disease-free survival rates were 66.7 and 53%, respectively, with a median follow-up of 25 months for surviving patients. Therefore, BuFlu was an effective conditioning regimen with a low rate of transplant-related adverse effects and increased antileukemic effects in patients with acute leukemia undergoing allo-HSCT.

  13. Induction with cross-classified categories.

    1999-11-01

    One of the main functions of categories is to allow inferences about new objects. However, most objects are cross-classified, and it is not known whether and how people combine information from these different categories in making inferences. In six experiments, food categories, which are strongly cross-classified (e.g., a bagel is both a bread and a breakfast food), were studied. For each food, the subjects were told fictitious facts (e.g., 75% of breads are subject to spoilage from Aspergillus molds) about two of the categories to which it belonged and then were asked to make an inference about the food (e.g., how likely is a bagel to be subject to spoilage from Aspergillus molds?). We found no more use of multiple categories in these cases of cross-classification than in ambiguous classification, in which it is uncertain to which category an item belongs. However, some procedural manipulations did markedly increase the use of both categories in inferences, primarily those that focused the subjects' attention on the critical feature in both categories.

  16. Can height categories replace weight categories in striking martial arts competitions? A pilot study.

    In most combat sports and martial arts, athletes compete within weight categories. Disordered eating behaviors and intentional pre-competition rapid weight loss are commonly seen in this population, attributed to weight categorization. We examined if height categories can be used as an alternative to weight categories for competition, in order to protect the health of athletes. Height and weight of 169 child and adolescent competitive karate athletes were measured. Participants were divided into eleven hypothetical weight categories of 5 kg increments, and eleven hypothetical height categories of 5 cm increments. We calculated the coefficient of variation of height and weight by each division method. We also calculated how many participants fit into corresponding categories of both height and weight, and how many would shift a category if divided by height. There was a high correlation between height and weight (r = 0.91, p<0.001). The mean range of heights seen within current weight categories was reduced by 83% when participants were divided by height. When allocating athletes by height categories, 74% of athletes would shift up or down one weight category at most, compared with the current categorization method. We conclude that dividing young karate athletes by height categories significantly reduced the range of heights of competitors within the category. Such categorization would not cause athletes to compete against much heavier opponents in most cases. Using height categories as a means to reduce eating disorders in combat sports should be further examined. PMID:26557193

    1992-06-01

    The aim of this paper is to give a concise introduction to the theory of knot invariants and 3-manifold invariants which generalize the Jones polynomial and which may be considered as a mathematical version of the Witten invariants. Such a theory was introduced by N. Reshetikhin and the author on the ground of the theory of quantum groups. here we use more general algebraic objects, specifically, ribbon and modular categories. Such categories in particular arise as the categories of representations of quantum groups. The notion of modular category, interesting in itself, is closely related to the notion of modular tensor category in the sense of G. Moore and N. Seiberg. For simplicity we restrict ourselves in this paper to the case of closed 3-manifolds.

  19. Diagnostic Categories in Autobiographical Accounts of Illness.

    PubMed

    Kelly, Michael P

    2015-01-01

    Working within frameworks drawn from the writings of Immanuel Kant, Alfred Schutz, and Kenneth Burke, this article examines the role that diagnostic categories play in autobiographical accounts of illness, with a special focus on chronic disease. Four lay diagnostic categories, each with different connections to formal medical diagnostic categories, serve as typifications to make sense of the way the lifeworld changes over the course of chronic illness. These diagnostic categories are used in conjunction with another set of typifications: lay epidemiologies, lay etiologies, lay prognostics, and lay therapeutics. Together these serve to construct and reconstruct the self at the center of the lifeworld. Embedded within the lay diagnostic categories are narratives of progression, regression, or stability, forms of typification derived from literary and storytelling genres. These narratives are developed by the self in autobiographical accounts of illness. PMID:26657684

  20. Risk categories and refractory CLL in the era of chemoimmunotherapy

    Standardized criteria for diagnosis and response evaluation in chronic lymphocytic leukemia (CLL) are essential to achieve comparability of results and improvement of clinical care. With the increasing range of therapeutic options, the treatment context is important when defining refractory CLL. Refractory CLL has been defined as no response or response lasting ≤ 6 months from last therapy. This subgroup has a very poor outcome, and many trials use this group as an entry point for early drug development. With the intensification of first-line regimens, the proportion of patients with refractory CLL using these criteria decreases. This has immediate consequences for recruitment of patients into trials as well as salvage strategies. Conversely, patients who are not refractory according to the traditional definition but who have suboptimal or short response to intense therapy also have a very poor outcome. In this Perspective, we discuss recent results that may lead to a reassessment of risk categories in CLL focusing on fit patients who are eligible for all treatment options. We cover aspects of the history and biologic basis for refractory CLL and will focus on how emerging data on treatment failure from large trials using chemoimmunotherapy may help to define risk groups in CLL.

    Obinutuzumab (GA101) is a type II, glycoengineered anti-CD20 monoclonal antibody for the treatment of hematologic malignancies. Obinutuzumab has mechanisms of action that are distinct from those of rituximab, potentially translating into improved clinical efficacy. We present the pharmacokinetic and clinical data from the phase I/II GAUGUIN and phase I GAUDI studies that were used to identify the obinutuzumab dose and regimen undergoing phase III assessment. In phase I (GAUGUIN and GAUDI), non-Hodgkin lymphoma patients received up to a maximum 9 fixed doses (obinutuzumab 50–2000 mg). In GAUGUIN phase II, patients received obinutuzumab 400/400 mg or 1600/800 mg [first dose day (D)1, D8, cycle (C) 1; second dose D1, C2–C8]. The influence of demographic factors on pharmacokinetics and drug exposure on tumor response and toxicity were analyzed using exploratory graphical analyses. Obinutuzumab serum concentrations with 1600/800 mg were compared with a 1000 mg fixed-dose regimen (D1, D8 and D15, C1; D1, C2–C8) using pharmacokinetic modeling simulations. Factors related to CD20-antigenic mass were more influential on obinutuzumab pharmacokinetics with 400/400 versus 1600/800 mg. Higher serum concentrations were observed with 1600/800 versus 400/400 mg, irrespective of CD20-antigenic mass. Tumor shrinkage was greater with 1600/800 versus 400/400 mg; there was no significant increase in adverse events. Fixed dose 1000 mg with an additional C1 infusion resulted in similar serum concentrations to 1600/800 mg in model-based analyses. The obinutuzumab 1000 mg fixed-dose regimen identified in this exploratory analysis was confirmed in a full covariate analysis of a larger dataset, and is undergoing phase III evaluation. GAUGUIN and GAUDI are registered at www.clinicaltrials.gov (clinicaltrials.gov identifier:00517530 and 00825149, respectively). PMID:26659915

    Objective Recent research has identified specific cognitive deficits in patients with anorexia nervosa (AN), including impairment in executive functioning and attention. Another such cognitive process, implicit category learning has been less studied in AN. This study examined whether implicit category learning is impaired in AN. Method Twenty-one women diagnosed with AN and 19 control women (CW) were administered an implicit category learning task in which they were asked to categorize simple perceptual stimuli (Gabor patches) into one of two categories. Category membership was based on a linear integration (i.e., an implicit task) of two stimulus dimensions (orientation and spatial frequency of the stimulus). Results AN individuals were less accurate on implicit category learning relative to age-matched CW. Model-based analyses indicated that, even when AN individuals used the appropriate (i.e., implicit) strategy they were still impaired relative to CW who also used the same strategy. In addition, task performance in AN patients was worse the higher they were in self-reported novelty seeking and the lower they were in sensitivity to punishment. Conclusions These results indicate that AN patients have implicit category learning deficits, and given this type of learning is thought to be mediated by striatal dopamine pathways, AN patients may have deficits in these neural systems. The finding of significant correlations with novelty seeking and sensitivity to punishment suggests that feedback sensitivity is related to implicit learning in AN. PMID:22201300

    The goal of therapy in chronic hepatitis C virus (HCV) infection is sustained virological response (SVR) which reflects HCV eradication. Treatment against HCV has dramatically improved with the recent availability of direct-acting antivirals (DAAs) including sofosbuvir, simeprevir, daclatasvir, ledipasvir/sofosbuvir, paritaprevir/ombitasvir and dasabuvir. Carefully selected combinations of these DAAs offer the potential for highly effective all-oral safe regimens even for patients with decompensated cirrhosis or liver transplant (LT) recipients. Like all current protease inhibitors, simeprevir and paritaprevir should not be used in patients with Child C cirrhosis, while sofosbuvir and ledipasvir/sofosbuvir should not be given in patients with severe renal impairment and glomerular filtration rate less than 30 mL/min. Drug-drug interactions may still occur with the current DAAs particularly in post-LT patients, in whom simeprevir should not be co-administered with cyclosporine and dose adjustments of calcineurin inhibitors are required in case of regimens including the ritonavir boosted paritaprevir. Phase II clinical trials and real life cohort studies have shown that sofosbuvir based combinations are safe and can achieve improvements of clinical status, high SVR rates and even prevention of post-LT HCV recurrence in patients with decompensated cirrhosis or LT-candidates. In the post-LT setting, sofosbuvir based regimens and the combination of paritaprevir/ombitasvir and dasabuvir have been reported to be safe and achieve high SVR rates, similar to those in non-transplant patients, being effective even in cases with cholestatic fibrosing hepatitis. Ongoing clinical trials and rapidly emerging real life data will further clarify the safety and efficacy of the new regimens in these settings. PMID:26327760

    Background Despite the high prevalence of HIV in correctional settings, the duration of therapy and response to various highly active antiretroviral therapy (HAART) regimens in this setting is unknown. Method Using a retrospective cohort study (1997−2002) of HIV-infected prisoners in Connecticut that linked demographic, pharmacy, and laboratory data, we compared HIV-1 RNA (VL) and CD4 lymphocyte responses to four treatment strategies at baseline and at the end of incarceration. Results Using an analysis of 1,044 incarceration periods or 1,099 subjects for whom ≥6 months of continuous data were available, HAART regimens that included a triple NRTI, two NRTIs + either a PI or NNRTI, or a three-class (NRTI+NNRTI+PI) strategy demonstrated no difference in virological and immunological outcomes. The proportion of subjects who were initiated with NRTI, NNRTI, PI, or three-class regimens were 14%, 32%, 46%, and 8%, respectively. For all study groups, the mean change from baseline in CD4 and VL was +74 cells/μL and −0.93 log10 copies/mL (p < .0001), respectively. Overall, 59% of subjects had an HIV-1 RNA level below the level of detection (<400 copies/mL) by the end of their incarceration. Using Kaplan-Meier curves to examine the time to change in the initial HAART strategy over the incarceration period, the three-class strategy was significantly more likely to be changed earlier than all others (p < .05). Conclusion Although the three-class strategy was less durable, initiating HAART with any strategy resulted in similar and impressive virological and immunological outcomes by the end of incarceration, further supporting prison as an important site for the initiation and provision of effective antiretroviral therapy.

The model was trained on 4,800 images of common objects, and CCFs were obtained for 68 categories spanning subordinate, basic, and superordinate levels in a category hierarchy. When participants searched for these same categories, targets cued at the subordinate level were preferentially fixated, but fixated targets were verified faster when they followed a basic-level cue. The subordinate-level advantage in guidance is explained by the number of target-category CCFs, a measure of category specificity that decreases with movement up the category hierarchy. The basic-level advantage in verification is explained by multiplying the number of CCFs by sibling distance, a measure of category distinctiveness. With this model, the visual representations of real-world object categories, each learned from the vast numbers of image exemplars accumulated throughout everyday experience, can finally be studied.

    A pharmacokinetic slide rule to facilitate the computations based on relatively simple pharmacokinetic principles involved in the development of individualized drug dosage regimens is described. The calculations are based on the assumption that the body can be conceived as a one-compartment open model with drug elimination proceeding by apparent first-order kinetics. Examples are presented (1) to illustrate the clinical application of a slide rule to compute the time-course of drug in the body, (2) to calculate steady-state maximum and minimum levels, and accumulation during multiple dosage and (3) to estimate appropriate maintenance doses and intravenous infusion rates.

  19. On Gauging Symmetry of Modular Categories

    2016-05-01

    Topological order of a topological phase of matter in two spacial dimensions is encoded by a unitary modular (tensor) category (UMC). A group symmetry of the topological phase induces a group symmetry of its corresponding UMC. Gauging is a well-known theoretical tool to promote a global symmetry to a local gauge symmetry. We give a mathematical formulation of gauging in terms of higher category formalism. Roughly, given a UMC with a symmetry group G, gauging is a 2-step process: first extend the UMC to a G-crossed braided fusion category and then take the equivariantization of the resulting category. Gauging can tell whether or not two enriched topological phases of matter are different, and also provides a way to construct new UMCs out of old ones. We derive a formula for the {H^4} -obstruction, prove some properties of gauging, and carry out gauging for two concrete examples.

    Background/Aims This study assessed the efficacy of a rifaximin plus levofloxacin-based rescue regimen in patients that had failed both triple and quadruple standard regimens for the eradication of Helicobacter pylori. Methods We treated patients for H. pylori between August 2009 and April 2011. The triple regimen consisted of combined treatment with amoxicillin, clarithromycin, and pantoprazole for 1 week. For failed cases, a quadruple regimen of tetracycline, metronidazole, bismuth dicitrate, and lansoprazole for 1 week was administered. The rescue regimen for persistently refractory cases was rifaximin 200 mg t.i.d., levofloxacin 500 mg q.d., and lansoprazole 15 mg b.i.d. for 1 week. Results In total, 482 patients were enrolled in this study. The eradication rates associated with the first and second regimens were 58% and 60%, respectively. Forty-seven out of 58 patients who failed with the second-line regimen received rifaximin plus levofloxacin-based third-line therapy. The eradication rate for the third regimen was 65%. The cumulative eradication rates were 58%, 85%, and 96% for each regimen, respectively. Conclusions A rifaximin plus levofloxacin-based regimen could be an alternative rescue therapy in patients with resistance to both triple and quadruple regimens for the eradication of H. pylori.

    The findings of Shepard, Hovland, and Jenkins (1961) on the relative ease of learning 6 elemental types of 2-way classifications have been deeply influential 2 times over: 1st, as a rebuke to pure stimulus generalization accounts, and again as the leading benchmark for evaluating formal models of human category learning. The litmus test for models is the ability to simulate an observed advantage in learning a category structure based on an exclusive-or (XOR) rule over 2 relevant dimensions (Type II) relative to category structures that have no perfectly predictive cue or cue combination (including the linearly-separable Type IV). However, a review of the literature reveals that a Type II advantage over Type IV is found only under highly specific experimental conditions. We investigate when and why a Type II advantage exists to determine the appropriate benchmark for models and the psychological theories they represent. A series of 8 experiments link particular conditions of learning to outcomes ranging from a traditional Type II advantage to compelling non-differences and reversals (i.e., Type IV advantage). Common interpretations of the Type II advantage as either a broad-based phenomenon of human learning or as strong evidence for an attention-mediated similarity-based account are called into question by our findings. Finally, a role for verbalization in the category learning process is supported. PMID:22799282

    We compare the evolutionary fitness of different cultures (or populations), where we think of culture as partitioning a set of decision situations into categories of situations treated the same. Information about optimal behavior in each category is passed on via a process of noisy cultural transmission. We show that coarse partitions (distinguishing less situations) can provide higher evolutionary fitness even if there are no explicit costs to holding finer partitions. PMID:22659044

    Background This study investigated the pharmacokinetics of fosmidomycin when given in combination with clindamycin at two dosage regimens in patients with acute uncomplicated falciparum malaria. Methods A total of 70 patients with acute uncomplicated Plasmodium falciparum malaria who fulfilled the enrolment criteria were recruited in the pharmacokinetic study. Patients were treated with two different dosage regimens of fosmidomycin in combination with clindamycin as follows: Group I: fosmidomycin (900 mg) and clindamycin (300 mg) every 6 hours for 3 days (n = 25); and Group II: fosmidomycin (1,800 mg) and clindamycin (600 mg) every 12 hours for 3 days (n = 54). Results Both regimens were well tolerated with no serious adverse events. The 28-day cure rates for Group I and Group II were 91.3 and 89.7%, respectively. Steady-state plasma concentrations of fosmidomycin and clindamycin were attained at about 24 hr after the first dose. The pharmacokinetics of both fosmidomycin and clindamycin analysed by model-independent and model-dependent approaches were generally in broad agreement. There were marked differences in the pharmacokinetic profiles of fosmidomycin and clindamycin when given as two different combination regimens. In general, most of the dose-dependent pharmacokinetic parameters (model-independent Cmax: 3.74 vs 2.41 μg/ml; Cmax-ss: 2.80 vs 2.08 μg/ml; Cmax-min-ss: 2.03 vs 0.71 μg/ml; AUC: 23.31 vs 10.63 μg.hr/ml (median values) were significantly higher in patients who received the high dose regimen (Group II). However, Cmin-ss was lower in this group (0.80 vs 1.37 μg/ml), resulting in significantly higher fluctuations in the plasma concentrations of both fosmidomycin and clindamycin following multiple dosing (110.0 vs 41.9%). Other pharmacokinetic parameters, notably total clearance (CL/F), apparent volume of distribution (V/F, Vz/F) and elimination half-life (t1/2z, t1/2e) were also significantly different between the two dosage regimens. In addition

  4. On the flexibility of phonetic categories

    2002-05-01

    Research on phonetic category acquisition suggests that over the course of development children shift the relative weight given to various acoustic cues to particular phonetic categories [S. Nittrouer, J. Phon. 20, 1-32 (1992)]. Adults also show flexibility in acquiring second language categories and learning to recognize synthetic speech. In both cases listeners must shift attention among some acoustic cues and change the weighting and mapping of others. Recent research demonstrated that category-level feedback can induce adult listeners to shift attention between conflicting cues to native stop-consonant categories. Subsequent research showed that adult listeners also reorganize the distribution of their attention to acoustic cues in learning to better understand synthetic speech. Moreover, research on learning foreign phonetic contrasts suggests that listeners can learn to direct attention to unfamiliar acoustic cues. These results suggest that phonetic categories are flexible in terms of the nature and quality of the acoustic cues that define them. We argue that this flexibility is a consequence of the basic nature of the general mechanism that mediates speech perception: In order to resolve the problem of context-conditioned variability, listeners must dynamically modify attention to the acoustic signal in a context-dependent manner.

  5. Liver irradiation: a potential preparative regimen for hepatocyte transplantation.

    Advances in the understanding of hepatocyte engraftment and repopulation of the host liver have already led to the use of hepatocyte transplantation (HT) with some success in the treatment of inherited and acquired liver diseases. Wider application of HT is severely limited by the unavailability of large number of transplantable hepatocytes and difficulties associated with transplanting an adequate number of cells for achieving therapeutically satisfactory levels of metabolic correction. Therefore, there is a need for preparative regimens that provide a growth advantage to the transplanted (healthy) hepatocytes over the host's own (diseased) hepatocytes so that the former can repopulate the host liver. We have recently shown that when the liver of recipient rats was subjected to radiotherapy and partial hepatectomy before HT, the transplanted hepatocytes engrafted in and massively repopulated the liver, and also ameliorated the adverse clinical and histopathological changes associated with hepatic irradiation. This protocol was then used as a preparative regimen for transplanting normal hepatocytes into jaundice mutant rats (Gunn strain), which lack hepatic bilirubin-uridinediphosphoglucuronate glucuronosyltransferase and is a model of Crigler-Najjar syndrome Type I. The results showed long-term correction of the metabolic abnormality, suggesting that the transplanted hepatocytes repopulated an irradiated liver and were metabolically functional. This strategy could be useful in the treatment of various genetic, metabolic, or malignant diseases of the liver. PMID:11173140

    2016-04-01

    There is an extensive literature regarding nonadherence with both therapeutic regimens and medication. This literature includes reviews of empirical research regarding the factors associated with nonadherence. Health care system, provider, and patient factors as well as the nature of the illness and therapeutic regimen all effect adherence rates. Different behavioral models for adherence counseling such as the Health Belief Model, the Theory of Reasoned Action, the Medication Interest Model, and Motivational Interviewing have also been reported in the research literature. This article will discuss the development of a brief model for patient counseling with specific techniques illustrated for pharmacists based on empirical findings that have demonstrated effectiveness in the adherence research literature. In addition, the article will address the measurement of the economic impact of medication nonadherence and propose a framework for assessing the cost-effectiveness of pharmacist counseling to increase adherence. The problem of nonadherence has significant effects upon health care expenditures through increase in physician's visits, emergency department incidents, rehospitalizations, and nursing home readmissions. Thus, the overall goal is to assist the pharmacist in developing a brief adherence counseling program in community pharmacy and evaluating the economic feasibility of the intervention demonstrating the value-added proposition of pharmacist intervention.

    Without any doubt the regimen used to mature multiple capable oocytes for IVF impacts IVF outcomes. Studies have indicated that the inclusion of LH activity, adjuvant agents such as growth hormone (GH), and regimens providing for simultaneous action of both LH and FSH during final oocyte maturation may have beneficial effects on IVF outcomes. Because of the difficulty in improving IVF outcomes in poor responders, the studies on GH are of particular interest. As pointed out in this review, the apparent beneficial effects of GH on oocyte competence may also apply to older women or to normal responders with reduced embryo quality. A much more difficult question is whether and how much ovarian stimulation impacts on oocyte competence. Paradoxically it seems that there are not demonstrated differences between the stimulated and the natural unstimulated cycle, whereas studies in laboratory animals and IVF patients have shown deleterious effects of higher compared with lower doses of gonadotropins. Recent studies suggest that the use of high doses of gonadotropins as an independent factor correlates negatively with the probability of live birth, whereas a high ovarian response per se is associated with better cumulative pregnancy rates, owing to the availability of more euploid and good-quality embryos. Although adjunctive use of androgens has not been discussed here, it is briefly covered in the first review of this series. PMID:26826273

    Objective: To assess whether the number of daily administrations of individual drugs, as a measure of regimen complexity, contributes to the profile of an elderly patient who adheres poorly to the prescribed therapy. Population: Six hundred ninety patients over 64 years who were consecutively admitted to 11 acute medical care and three long term/rehabilitation wards in Italy. Main outcome measure: Self-reported adherence to drugs taken at home before admission was measured by a single question assessment for each listed drug supplemented with a latter question about the circumstances of the missed administration. For cognitively impaired patients the question was put to patients’ relatives or caregivers. Methods: A structured multidimensional assessment was performed to identify nonadherence and its potential correlates. Correlates of nonadherence were identified by multivariable logistic regression. Results: We recorded 44 cases (6.4%) of nonadherence to at least one drug. Being assisted by foreign caregivers (OR 2.17; 95% CI 1.02–4.63) and the use of at least one multiple daily dosing drug (OR 2.99; 95% CI 1.24–7.17) were significant independent correlates of medication nonadherence, while age, selected indexes of frailty and the cumulative number of prescribed drugs were not. Conclusion: Regimen complexity and type of assistance are independent correlates of medication nonadherence. PMID:19436625

    This review is intended to help clinicians design drug regimens for special populations of critically ill patients with extremes of body size, habitus and composition that make drug choice or dosing particularly challenging due to the lack of high-level evidence on which to make well-informed clinical decisions. The data sources included a literature search of MEDLINE and EMBASE with reviews of reference lists of retrieved articles. Abstracts of original research investigations and review papers were reviewed for their relevance to drug choice or dosing in the following special critically ill populations: patients with more severe forms of bodyweight or height, patients with amputations or missing limbs, pregnant patients, and patients undergoing extracorporeal membrane oxygenation or plasma exchange. Relevant papers were retrieved and evaluated, and their associated reference lists were reviewed for citations that may have been missed through the electronic search strategy. Relevant original research investigations and review papers that could be used to formulate general principles for drug choice or dosing in special populations of critically ill patients were extracted. Randomized studies with clinically relevant endpoints were not available for performing quantitative analyses. Critically ill patients with changes in body size, habitus and composition require special consideration when designing medication regimens, but there is a paucity of literature on which to make drug-specific, high-level evidence-based recommendations. Based on the evidence that is available, general recommendations are provided for drug choice or dosing in special critically ill populations. PMID:25938029

    The aim of this study was to validate a simplified high-dosage, extended-interval netilmicin dosage regimen for infants. A total of 129 infants receiving 163 treatment courses of netilmicin (6 mg kg every 24 or 36 h depending on gestational age (GA), postnatal age and postmenstrual age) was analysed. Serum netilmicin concentrations were monitored before (Cmin), 30 min (C0.5h) after and 7.5 h (C7.5h) after the third dose. In 110 patients during first week of life mean C0.5h was 10.5 mg/l. Mean C0.5h was significantly lower (9.0 mg/l) in 38 infants older than 1 week of age. 14 of 15 patients with Cmin levels > or = 2 mg/l receiving netilmicin every 36 h were < 28 weeks of gestation. In the first week of life significant correlations between GA and elimination half-life (p < 0.001) and between plasma creatinine and elevated Cmin (p < 0.002) were found, but no correlation between C0.5h and GA. In this high-dosage regimen a dosing interval of 48 h for GA < 29 weeks, 36 h for GA 29-36 weeks and 24 h for full term babies seems appropriate, during first week of life, to avoid the majority of elevated trough levels and still obtain maximal therapeutic efficacy.

  11. When does fading enhance perceptual category learning?

    PubMed

    Pashler, Harold; Mozer, Michael C

    2013-07-01

    Training that uses exaggerated versions of a stimulus discrimination (fading) has sometimes been found to enhance category learning, mostly in studies involving animals and impaired populations. However, little is known about whether and when fading facilitates learning for typical individuals. This issue was explored in 7 experiments. In Experiments 1 and 2, observers discriminated stimuli based on a single sensory continuum (time duration and line length, respectively). Adaptive fading dramatically improved performance in training (unsurprisingly) but did not enhance learning as assessed in a final test. The same was true for nonadaptive linear fading (Experiment 3). However, when variation in length (predicting category membership) was embedded among other (category-irrelevant) variation, fading dramatically enhanced not only performance in training but also learning as assessed in a final test (Experiments 4 and 5). Fading also helped learners to acquire a color saturation discrimination amid category-irrelevant variation in hue and brightness, although this learning proved transitory after feedback was withdrawn (Experiment 7). Theoretical implications are discussed, and we argue that fading should have practical utility in naturalistic category learning tasks, which involve extremely high dimensional stimuli and many irrelevant dimensions.

    Creationism implies that God imbued each category with a unique nature and purpose. These implications closely correspond to what some cognitive psychologists define as an essentialistic and teleological stance towards categories. This study assessed to what extent the belief in God as creator of categories is related to the mappings of these stances to categories in different domains. Israeli secular and orthodox Jewish 1st and 5th graders responded to questions assessing these three types of beliefs. The results revealed that secular children did not differ from orthodox children with respect to their essentialist beliefs about the stability of animal category membership, and their teleological construal of artifacts. In turn, secular children did differ from orthodox children with respect to their essentialist beliefs about the stability of social category membership, and their teleological construal of both animal and social categories. These findings intimate that while essentialist beliefs about animals, and teleological beliefs about artifacts do not require cultural input in order to emerge, essentialist beliefs about social categories, and teleological beliefs about both animal and social categories do.

    Abstract To establish the comparative effectiveness of all available biologic therapy regimens for ankylosing spondylitis, we performed a systematic review and a Bayesian network meta-analysis of randomized controlled trials. PubMed, Medline, Embase, Cochrane library, and ClinicalTrials.gov were searched from the inception of each database to June 2015. Systematic review and network meta-analysis was reported according to the Preferred Reporting Items of Systematic Reviews and Meta-Analyses Extension Statement for Reporting of Systematic Reviews Incorporating Network Meta-analyses. The primary outcome was 20% improvement of Assessments in SpondyloArthritis International Society Response Criteria (ASAS20) at Week 12 or 14; secondary outcomes were ASAS40, ASAS5/6, ASAS partial remission and 50% improvement in baseline Bath ankylosing spondylitis (AS) disease activity index. We reported relative risks and 95% confidence intervals from direct meta-analysis and 95% credible intervals from Bayesian network meta-analysis, and ranked the treatment for outcomes. We also used Grading of Recommendations Assessment, Development and Evaluation criteria to appraise quality of evidence. Fourteen RCTs comprising 2672 active AS patients were included in the network meta-analysis. Most biologic therapy regimens were more effective than placebo regarding all the outcomes assessed, except for secukinumab and tocilizumab. No differences between biologic therapies in the treatment of AS could be found, except for the finding that infliximab 5 mg was superior to tocilizumab. Infliximab 5 mg/kg had the highest probability of being ranked the best for achieving ASAS20, whereas notably, secukinumab had the highest probability of being ranked the second best. Our study suggests that no differences between biologic therapies in the treatment of AS could be found except that infliximab 5 mg was superior to tocilizumab. Infliximab 5 mg/kg seems to be the better biologic therapy regimen

    2015-01-01

    Background: Lung functions are found to be impaired in coronary artery disease (CAD), congestive heart failure, left ventricular dysfunction, and after cardiac surgery. Diffusion capacity progressively worsens as the severity of CAD increases due to reduction in lung tissue participating in gas exchange. Aims and Objectives: Pranayama breathing exercises and yogic postures may play an impressive role in improving cardio-respiratory efficiency and facilitating gas diffusion at the alveolo-capillary membrane. This study was done to see the effect of yoga regimen on lung functions particularly diffusion capacity in CAD patients. Materials and Methods: A total of 80 stable CAD patients below 65 years of age of both sexes were selected and randomized into two groups of 40 each. Group I CAD patients were given yoga regimen for 3 months which consisted of yogic postures, pranayama breathing exercises, dietary modification, and holistic teaching along with their conventional medicine while Group II CAD patients were put only on conventional medicine. Lung functions including diffusion capacity were recorded thrice in both the groups: 0 day as baseline, 22nd day and on 90th day by using computerized MS medisoft Cardio-respiratory Instrument, HYP’AIR Compact model of cardio-respiratory testing machine was manufactured by P K Morgan, India. The recorded parameters were statistically analyzed by repeated measures ANOVA followed by Tukey's test in both the groups. Cardiovascular parameters were also compared before and after intervention in both the groups. Results: Statistically significant improvements were seen in slow vital capacity, forced vital capacity, peak expiratory flow rate, maximum voluntary ventilation, and diffusion factor/ transfer factor of lung for carbon monoxide after 3 months of yoga regimen in Group I. Forced expiratory volume in 1st sec (FEV1), and FEV1 % also showed a trend toward improvement although not statistically significant. HR, SBP and DBP also

  17. From Perceptual Categories to Concepts: What Develops?

    2010-01-01

    People are remarkably smart: they use language, possess complex motor skills, make non-trivial inferences, develop and use scientific theories, make laws, and adapt to complex dynamic environments. Much of this knowledge requires concepts and this paper focuses on how people acquire concepts. It is argued that conceptual development progresses from simple perceptual grouping to highly abstract scientific concepts. This proposal of conceptual development has four parts. First, it is argued that categories in the world have different structure. Second, there might be different learning systems (sub-served by different brain mechanisms) that evolved to learn categories of differing structures. Third, these systems exhibit differential maturational course, which affects how categories of different structures are learned in the course of development. And finally, an interaction of these components may result in the developmental transition from perceptual groupings to more abstract concepts. This paper reviews a large body of empirical evidence supporting this proposal. PMID:21116483

  18. Concepts and Categories: A Cognitive Neuropsychological Perspective

    Mahon, Bradford Z.; Caramazza, Alfonso

    2010-01-01

    One of the most provocative and exciting issues in cognitive science is how neural specificity for semantic categories of common objects arises in the functional architecture of the brain. More than two decades of research on the neuropsychological phenomenon of category-specific semantic deficits has generated detailed claims about the organization and representation of conceptual knowledge. More recently, researchers have sought to test hypotheses developed on the basis of neuropsychological evidence with functional imaging. From those two fields, the empirical generalization emerges that object domain and sensory modality jointly constrain the organization of knowledge in the brain. At the same time, research within the embodied cognition framework has highlighted the need to articulate how information is communicated between the sensory and motor systems, and processes that represent and generalize abstract information. Those developments point toward a new approach for understanding category specificity in terms of the coordinated influences of diverse regions and cognitive systems. PMID:18767921

    The BEAM regimen consisting of carmustine (BCNU), etoposide, cytarabine, and melphalan (MEL) is widely used before autologous hematopoietic stem cell transplantation (auto-HSCT) for lymphoma. However, intravenous BCNU is not available in Japan, and therefore, ranimustine (MCNU) has been used instead of BCNU (the MEAM regimen). We retrospectively analyzed the outcome of 79 adult patients who underwent auto-HSCT for lymphoma using this regimen in two centers, with 1- and 2-day dosing of MEL, respectively. Three-year overall survival (OS) and progression-free survival (PFS) probabilities were 77.3 and 56.5 % in the entire population and 71.7 and 58.0 % in patients with diffuse large B cell lymphoma. These outcomes were at least equivalent to those with the BEAM regimen. There was no regimen-related pulmonary toxicity. In a multivariate analysis, older age was the only factor that was significantly associated with for OS. In a comparison of the two MEL dosing schedules, while there was no significant differences in either OS or PFS, diarrhea was observed more frequently with 1-day dosing of MEL. In conclusion, the MEAM regimen appeared to be a promising conditioning regimen in auto-HSCT for lymphoma. A large prospective study is warranted to confirm the current findings. PMID:27365141

    Let M be a Riemannian manifold and 𝒫M be the space of all smooth paths on M. We describe geodesics on path space 𝒫M. Normal neighborhoods on 𝒫M have been discussed. We identify paths on M under “back-track” equivalence. Under this identification, we show that if M is complete, then geodesics on the path space yield a double category. This double category has a natural interpretation in terms of the worldsheets generated by freely moving (without any external force) strings.

    2012-01-01

    The free recall measure is one of the most popular measures in memory research. Using this measure, researchers can assess not only the amount of recall but also the strategy participants used to recall the material. Category clustering is a strategy participants often use when the input list is categorized. Unfortunately, computing category clustering measures is laborious. The present paper introduces a calculator that computes these measures for each participant using a platform that is accessible to most researchers in an attempt to make these measures more user-friendly.

    Research was conducted in the classification of lower-enrichment space nuclear reactor fuel in terms of its graded safeguards category and attractiveness level. Specifically, fuel with a 235U enrichment of less than 50% and greater than 20% (i.e., 49.9%) meets the criteria for a lower category of special-nuclear-material control and accountability. This fuel is considered to have an attractiveness level of "D" and therefore is classified as Category II material rather than the highest and most rigorous Category I. The net result is a more cost-effective and facilitated approach to the protection, control, and accountability of this material.

    Background Regimen selection for highly treatment-experienced patients is complicated. Methods Using a web-based utility, study team members reviewed antiretroviral (ARV) history and resistance data and recommended individual ARV regimens and nucleoside reverse transcriptase inhibitor (NRTI) options for treatment-experienced participants consisting of 3–4 of the following agents: raltegravir (RAL), darunavir (DRV)/ritonavir, tipranavir (TPV)/ritonavir, etravirine (ETR), maraviroc (MVC), and enfuvirtide (ENF). We evaluated team recommendations and site selection of regimen and NRTIs. Associations between baseline factors and the selection of a complex regimen (defined as including four ARV agents or ENF) were explored with logistic regression. Results A total of 413 participants entered the study. Participants initiated the first or second recommended regimen 86% of the time and 21% of participants started a complex regimen. In a multivariable model, ARV resistance to NRTI (odds ratio [OR]=2.2), non-nucleoside reverse transcriptase inhibitor (NNRTI, OR=6.2) or boosted protease inhibitor (PI, OR=6.6), prior use of integrase strand transfer inhibitor (INSTI, OR=25), and race–ethnicity (all P≤0.01) were associated with selection of a complex regimen. Black non-Hispanic (OR=0.5) and Hispanic participants from the continental US (OR=0.2) were less likely to start a complex regimen, compared to white non-Hispanics. Conclusions In this multi-center trial, we developed a web-based utility that facilitated treatment recommendations for highly treatment-experienced patients. Drug resistance, prior INSTI use, and race–ethnicity were key factors in decisions to select a more complex regimen. PMID:26212575

  9. Eradication of Helicobacter pylori: are rifaximin-based regimens effective?

    PubMed

    Gasbarrini, Antonio; Gasbarrini, Giovanni; Pelosini, Iva; Scarpignato, Carmelo

    2006-01-01

    Rifaximin is a non-absorbed semisynthetic rifamycin derivative with a broad spectrum of antibacterial activity including Gram-positive and Gram-negative bacteria, both aerobes and anaerobes. Although originally developed for the treatment of infectious diarrhea, the appreciation of the pathogenic role of gut bacteria in several organic and functional gastrointestinal diseases has increasingly broadened its clinical use. Being the antibiotic active against Helicobacter pylori, even towards clarithromycin-resistant strain, and being the primary resistance very rare, several investigations explored its potential use for eradication of the microorganism. Rifaximin alone proved to be effective, but even the highest dose (1,200 mg daily) gave a cure rate of only 30%. Dual and triple therapies were also studied, with the better results obtained with rifaximin-clarithromycin and rifaximin-clarithromycin-esomeprazole combinations. However, the eradication rates (60-70%) obtained with these regimens were still below the standard set by the Maastricht Consensus guidelines. Although rifaximin-based eradication therapies are promising, new antimicrobial combinations (with and without proton pump inhibitors) need to be explored in well-designed clinical trials including a large cohort of H. pylori-infected patients. The remarkable safety of rifaximin will allow high-dose regimens of longer duration (e.g. 10 or 14 days) to be tested with confidence in the hope of achieving better eradication rates. A drawback of rifaximin could be its inability to reach sufficiently high concentrations in the gastric mucus layer under and within which H. pylori is commonly located and this would likely affect eradication rate. Taking these considerations into account, bioadhesive rifaximin formulations able to better and persistently cover gastric mucosa, or combination with mucolytic agents, such as pronase or acetylcysteine, need to be evaluated in order to better define the place of this

    2012-01-01

    BACKGROUND Treatment of latent tuberculosis in patients infected with the human immunodeficiency virus (HIV) is efficacious, but few patients around the world receive such treatment. We evaluated three new regimens for latent tuberculosis that may be more potent and durable than standard isoniazid treatment. METHODS We randomly assigned South African adults with HIV infection and a positive tuberculin skin test who were not taking antiretroviral therapy to receive rifapentine (900 mg) plus isoniazid (900 mg) weekly for 12 weeks, rifampin (600 mg) plus isoniazid (900 mg) twice weekly for 12 weeks, isoniazid (300 mg) daily for up to 6 years (continuous isoniazid), or isoniazid (300 mg) daily for 6 months (control group). The primary end point was tuberculosis-free survival. RESULTS The 1148 patients had a median age of 30 years and a median CD4 cell count of 484 per cubic millimeter. Incidence rates of active tuberculosis or death were 3.1 per 100 person-years in the rifapentine–isoniazid group, 2.9 per 100 person-years in the rifampin–isoniazid group, and 2.7 per 100 person-years in the continuous-isoniazid group, as compared with 3.6 per 100 person-years in the control group (P>0.05 for all comparisons). Serious adverse reactions were more common in the continuous-isoniazid group (18.4 per 100 person-years) than in the other treatment groups (8.7 to 15.4 per 100 person-years). Two of 58 isolates of Mycobacterium tuberculosis (3.4%) were found to have multidrug resistance. CONCLUSIONS On the basis of the expected rates of tuberculosis in this population of HIV-infected adults, all secondary prophylactic regimens were effective. Neither a 3-month course of intermittent rifapentine or rifampin with isoniazid nor continuous isoniazid was superior to 6 months of isoniazid. PMID:21732833

    2016-01-01

    ABSTRACT Objectives: The clinical utility of extended regimen combined oral contraceptives (COCs) is increasingly being recognised. Our objective was to understand the attitudes of women and clinicians about the use of these regimens. We present the rationale for extended regimen COCs from a historical perspective, and trace their evolution and growing popularity in light of their clinical benefits. We conclude by offering potential strategies for counselling women about extended regimen COC options. Methods: We conducted a MEDLINE search to identify and summarise studies of extended regimen COCs, focusing on attitudes of women and clinicians regarding efficacy, safety/tolerability and fewer scheduled bleeding episodes and other potential benefits. Results: The body of contemporary literature on extended regimen COCs suggests that their contraceptive efficacy is comparable to that of conventional 28-day (i.e., 21/7) regimens. For women seeking contraception that allows infrequent scheduled bleeding episodes, particularly those who suffer from hormone withdrawal symptoms and cyclical symptoms (e.g., headache, mood changes, dysmenorrhoea, heavy menstrual bleeding), extended regimen COCs are an effective and safe option. Although satisfaction with extended regimen COCs in clinical trials is high, misperceptions about continuous hormone use may still limit the widespread acceptance of this approach. Conclusions: Despite the widespread acceptance among clinicians of extended regimen COCs as an effective and safe contraceptive option, these regimens are underused, likely due to a lack of awareness about their availability and utility among women. Improved patient education and counselling regarding the safety and benefits of extended regimen COCs may help women make more informed contraceptive choices. PMID:26572318
