The first and second authors are supported by the Royal Society (RGF\EA\181005 and URF\R\180015).The normaliser problem takes as input subgroups G and H of the symmetric group Sn, and asks one to compute NG(H). The fastest known algorithm for this problem is simply exponential, whilst more efficient algorithms are known for restricted classes of groups. In this paper, we will focus on groups with many orbits. We give a new algorithm for the normaliser problem for these groups that performs many orders of magnitude faster than previous implementations in GAP. We also prove that the normaliser problem for the special case G=Sn  is at least as hard as computing the group of monomial automorphisms of a linear code over any field of fixed prime order.Publisher PDFPeer reviewe

Evaluation of the Impact of an Antibiotic Time-out for Transition of IV Vancomycin to Oral Linezolid in Hospitalized Patients

Background: Oral linezolid is a broad-spectrum oxazolidinone antibiotic that offers advantages compared to intravenous (IV) vancomycin including no requirement for therapeutic drug monitoring, no need for home health or peripherally inserted central catheter (PICC) line placement, and opportunities for earlier hospital discharge due to the ease of continuing therapy outpatient. A medication use evaluation investigated if opportunities existed for oral linezolid over IV vancomycin among a randomized cohort of 100 patients initiated on IV vancomycin. Reviewers identified 15 patients who were candidates for transition to oral linezolid and calculated a potential cost avoidance of $125 per day of antibiotic therapy. The purpose of this study is to assess the feasibility of implementing an interdisciplinary approach for transitioning IV vancomycin to oral linezolid based on pharmacist-led transition criteria. Methods: This is an IRB-reviewed, single-center, quasi-experimental study at Baptist Hospital of Miami, a 900-bed tertiary community hospital. Included patients were \u3e18 years old, receiving IV vancomycin for \u3e48 hours, and admitted between January 10, 2023 and March 31, 2023. Patients were excluded if they had an active vasopressor order, were immunocompromised, or if the patient was receiving antibiotics for meningitis, endocarditis, febrile neutropenia, or surgical prophylaxis. A pharmacy resident was on-call to assess for oral linezolid candidates using antibiotic timeout criteria and intervened as appropriate. Continuous and categorical variables were evaluated using the Mann-Whitney U test and Fisher’s exact test, respectively. The primary outcome was total cost avoidance in patients transitioned from IV vancomycin to oral linezolid. Secondary outcomes included median hospital length of stay, median antibiotic treatment days, and incidence of thrombocytopenia and acute kidney injury, and pharmacist intervention acceptance rate. Results: Investigators screened 317 patients for study inclusion and 94 patients met criteria. 66 (70$5,538, with a total of $21 and$70 saved per inpatient and outpatient antibiotic treatment day, respectively. Median length of antibiotic treatment days was 6 days between both groups (p=0.3524). No statistically significant differences were observed between length of stay, length of antibiotic treatment days, or safety outcomes between the 2 groups. Acute kidney injury occurred in 1 patient receiving linezolid and 1 patient receiving IV vancomycin. Thrombocytopenia, defined as a \u3e50% drop in platelet count from baseline, occurred in 1 patient receiving provider-driven linezolid therapy. Conclusion: Pharmacist-driven transition criteria from IV vancomycin to linezolid therapy resulted in a positive cost avoidance strategy, with similar effect on hospital antibiotic treatment days and no difference in incidence of adverse effects. These results demonstrate the practicality of a pharmacist prospective antibiotic timeout and intervention strategy for patients receiving empiric or targeted Methicillin-resistant Staphylococcus aureus (MRSA) therapy

Assessment of a Pharmacist-Led Antibiotic Time-out for Transition of IV Vancomycin to Oral Linezolid

Introduction: Intravenous (IV) vancomycin requires therapeutic drug monitoring and line placement and may prolong hospital stay. Linezolid requires less monitoring, is orally bioavailable, and may expedite transitions of care. This study assessed the impact of a pharmacist-led antibiotic timeout for the transition from IV vancomycin to oral linezolid. Methods: This single-center, quasi-experimental study included admitted adult patients receiving IV vancomycin for over 48 hours. Patients receiving vasopressors, of immunocompromised status, or with specific antibiotic indications were excluded. The primary outcome was the pharmacist intervention acceptance rate. Secondary outcomes included median hospital length of stay, median antibiotic treatment days, and incidence of adverse effects. Results: Of the 317 screened patients, 94 were eligible for the antibiotic time-out assessment, of which 66 met the criteria for oral linezolid. Of those meeting the criteria, 27 interventions were made, of which 20 (74%) were accepted. The median length of antibiotic treatment days was six days between both groups (p = .352). No differences in safety outcomes were observed. Discussion: A pharmacist-led antibiotic timeout for IV vancomycin to oral linezolid resulted in a high intervention acceptance rate and increased oral linezolid use without impacting safety outcomes. These results support the use of this strategy for antimicrobial stewardship. Conclusion: This study illustrates the impact of a pharmacist-led antibiotic timeout for the transition from IV vancomycin to oral linezolid therapy as an antimicrobial stewardship tool

The impact of riluzole on neurobehavioral outcomes in preclinical models of traumatic and nontraumatic spinal cord injury: results from a systematic review of the literature

Study Design:Systematic review.Objective:To evaluate the impact of riluzole on neurobehavioral outcomes in preclinical models of nontraumatic and traumatic spinal cord injury (SCI).Methods:An extensive search of the literature was conducted in Medline, EMBASE, and Medline in Process. Studies were included if they evaluated the impact of riluzole on neurobehavioral outcomes in preclinical models of nontraumatic and traumatic SCI. Extensive data were extracted from relevant studies, including sample characteristics, injury model, outcomes assessed, timing of evaluation, and main results. The SYRCLE checklist was used to assess various sources of bias.Results:The search yielded a total of 3180 unique citations. A total of 16 studies were deemed relevant and were summarized in this review. Sample sizes ranged from 14 to 90, and injury models included traumatic SCI (n = 9), degenerative cervical myelopathy (n = 2), and spinal cord-ischemia (n = 5). The most commonly assessed outcome measures were BBB (Basso, Beattie, Besnahan) locomotor score and von Frey filament testing. In general, rats treated with riluzole exhibited significantly higher BBB locomotor scores than controls. Furthermore, riluzole significantly increased withdrawal thresholds to innocuous stimuli and tail flick latency following application of radiant heat stimuli. Finally, rats treated with riluzole achieved superior results on many components of gait assessment.Conclusion:In preclinical models of traumatic and nontraumatic SCI, riluzole significantly improves locomotor scores, gait function, and neuropathic pain. This review provides the background information necessary to interpret the results of clinical trials on the impact of riluzole in traumatic and nontraumatic SCI

Young people’s experiences using an on-demand mobile health sexual and reproductive health text message intervention in Kenya : qualitative study

Background: Digital health usability assessments can help explain how well mobile health (mHealth) apps targeting young people with sexual and reproductive health (SRH) information performed and whether the intended purpose was achieved. However, few digital health assessments have been conducted to evaluate young people’s perceptions regarding mHealth system interactions and content relevance on a wide range of SRH topics. In addition, the majority of randomized controlled trials (RCTs) have focused on push messaging platforms; therefore, the mHealth field lacks sufficient RCTs investigating on-demand mHealth SRH platforms. Objective: The objective of this study was to explore young people’s experiences using an on-demand SRH mHealth platform in Kenya. Methods: We used qualitative data related to the usability of an mHealth platform, Adolescent/Youth Reproductive Mobile Access and Delivery Initiatives for Love and Life Outcome (ARMADILLO), collected at the end of the intervention period. A total of 30 in-depth interviews (IDIs) were held with the intervention participants (15 women and 15 men) to elicit their experiences, opinions, and perspectives on the design and content of the ARMADILLO platform. The study participants were randomly selected from a list of intervention arm participants to participate in the IDIs. The interviews were later transcribed verbatim, translated into English, and coded and analyzed thematically using NVivo version 12 software (QSR International). Results: Respondents reported varied user experiences and levels of satisfaction, ranging from ease of use by the majority of the respondents to systematic frustrations that prevented some participants from progressing to other stages. Interesting features of the mHealth platform included the immediate response participants received when requesting messages, weekly remunerated quizzes, and perceived ability of educative and informative content and messages to change behaviors. Proposed enhancements to the platform included revising some concepts and words for easy understanding and increasing the interactivity of the platform, whereby young people could seek clarity when they came across difficult terms or had additional questions about the information they received. Conclusions: The importance of understanding the range of health literacy and technological variations when dealing with young people cannot be overemphasized. Young people, as mHealth end users, must be considered throughout intervention development to achieve optimum functionality. In addition, young people targeted with mHealth SRH interventions must be sensitized to the interactions on mHealth platforms or any other digital health apps if implemented in a nonresearch setting for optimal use by the targeted audience

Exploring contraception myths and misconceptions among young men and women in Kwale County, Kenya

BackgroundMyths and misconceptions around modern contraceptives have been associated with low contraceptive uptake in sub-Saharan Africa and Kenya in particular. Addressing persistent contraceptive knowledge gaps can make a significant contribution towards improved contraceptive uptake among young women. This qualitative study therefore sought to explore and understand young people's knowledge of modern contraception and to identify their key concerns regarding these methods.MethodsWe used focus group discussions (FGD) with vignette and writing activities to explore key myths and misconceptions around the use of contraceptives. Six FGDs (three for young men and three for young women) were conducted with a total of 28 young women and 30 young men from Kwale County, Kenya. We included 10 discussants aged 18-24 per FGD, one FGD had 8 participants. Predefined codes reflecting the discussion guides and emerging issues in the FGDs were used to develop the thematic coding framework. Our analysis followed a pattern of association on the key preset themes focusing on myths and misconceptions around contraceptive use.ResultsResults are presented under four key themes: awareness of contraception, myths and misconceptions around contraception, males' contraceptive narratives and young people's preferred sources of contraceptives. Both men and women participants reported basic awareness of contraceptives. A mixture of biological and social misconceptions were discussed and included perceptions that modern contraception: jeopardized future fertility, could result in problems conceiving or birth defects, made women promiscuous, was 'un-African', and would deny couples their sexual freedom. Compared to female respondents in the study, young men appeared to be strong believers of the perceived socio-cultural effects of contraceptives. On preferred sources of contraceptives, respondents reported on two main sources, pharmacies and public hospitals, however, they could not agree on which one was suitable for them.ConclusionsThis study revealed the presence of a mixture of biological and social myths and misconceptions around contraception, with young men also strongly adhering to these misconceptions. The low level of contraceptive knowledge, particularly on contraceptive fears as revealed by the study demonstrate critical gaps in sexual and reproductive health (SRH) knowledge among young people. Improved SRH literacy to address contraceptives' fears through appropriate and gender specific interventions to reach out to young men and women with factual SRH information may therefore contribute to increased uptake of SRH services including modern contraceptive methods

Busting contraception myths and misconceptions among youth in Kwale County, Kenya: results of a digital health randomised control trial

Objectives: The objective of this randomised controlled trial in Kenya was to assess the effect of delivering sexual and reproductive health (SRH) information via text message to young people on their ability to reject contraception-related myths and misconceptions. Design and setting: A three-arm, unblinded randomised controlled trial with a ratio of 1:1:1 in Kwale County, Kenya. Participants and interventions: A total of 740 youth aged 18–24 years were randomised. Intervention arm participants could access informational SRH text messages on-demand. Contact arm participants received once weekly texts instructing them to study on an SRH topic on their own. Control arm participants received standard care. The intervention period was 7 weeks. Primary outcome: We assessed change myths believed at baseline and endline using an index of 10 contraception- related myths. We assessed change across arms using difference of difference analysis. Results: Across arms, \u3c5% of participants did not have any formal education, \u3c10% were living alone, about 50% were single and \u3e80% had never given birth. Between baseline and endline, there was a statistically significant drop in the average absolute number of myths and misconceptions believed by intervention arm (11.1%, 95% CI 17.1% to 5.2%), contact arm (14.4%, 95% CI 20.5% to 8.4%) and control arm (11.3%, 95% CI 17.4% to 5.2%) participants. However, we observed no statistically significant difference in the magnitude of change across arms. Conclusions: We are unable to conclusively state that the text message intervention was better than text message ‘contact’ or no intervention at all. Digital health likely has potential for improving SRH-related outcomes when used as part of multifaceted interventions. Additional studies with physical and geographical separation of different arms is warranted
