Abstract
Background: Exposure in utero to certain medications can disrupt processes of fetal development, including brain development, leading to a continuum of neurodevelopmental difficulties. Recognizing the deficiency of neurodevelopmental investigations within pregnancy pharmacovigilance, an international Neurodevelopmental Expert Working Group was convened to achieve consensus regarding the core neurodevelopmental outcomes, optimization of methodological approaches and barriers to conducting pregnancy pharmacovigilance studies with neurodevelopmental outcomes. Methods: A modified Delphi study was undertaken based on stakeholder and expert input. Stakeholders (patient, pharmaceutical, academic and regulatory) were invited to define topics, pertaining to neurodevelopmental investigations in medication-exposed pregnancies. Experts were identified for their experience regarding neurodevelopmental outcomes following medicinal, substances of misuse or environmental exposures in utero. Two questionnaire rounds and a virtual discussion meeting were used to explore expert opinion on the topics identified by the stakeholders. Results: Twenty-five experts, from 13 countries and professionally diverse backgrounds took part in the development of 11 recommendations. The recommendations focus on the importance of neurodevelopment as a core feature of pregnancy pharmacovigilance, the timing of study initiation and a core set of distinct but interrelated neurodevelopmental skills or diagnoses which require investigation. Studies should start in infancy with an extended period of investigation into adolescence, with more frequent sampling during rapid periods of development. Additionally, recommendations are made regarding optimal approach to neurodevelopmental outcome measurement, comparator groups, exposure factors, a core set of confounding and mediating variables, attrition, reporting of results and the required improvements in funding for potential later emerging effects. Different study designs will be required depending on the specific neurodevelopmental outcome type under investigation and whether the medicine in question is newly approved or already in widespread use. Conclusion: An improved focus on neurodevelopmental outcomes is required within pregnancy pharmacovigilance. These expert recommendations should be met across a complementary set of studies which converge to form a comprehensive set of evidence regarding neurodevelopmental outcomes in pregnancy pharmacovigilance.

Abstract
Abstract
Background: PRMT5 is an epigenetic enzyme that catalyzes symmetric dimethylation of arginine substrates (SDMA), regulating multiple cell processes. The PRMT5-MTAP collateral vulnerability describes the accumulation of the metabolite methylthioadenosine (MTA) in tumor cells (as a result of the deletion of the MTAP gene), which acts as a natural endogenous partial inhibitor of PRMT5. This provides an opportunity to selectively inhibit PRMT5 in MTAP deleted tumors, which occurs in ~15% of all cancers. First generation PRMT5 inhibitors, which cannot discriminate between MTAP-proficient normal cells and MTAP-deficient tumor cells, have a narrow therapeutic index which may limit clinical efficacy due to on-target toxicity. MTAP-selective PRMT5 inhibitors spare MTAP-proficient normal cells, improving therapeutic index and clinical efficacy. We have developed a novel MTAP-selective PRMT5 inhibitor, AZ-PRMT5i-1, that selectively targets MTAP-deficient tumors and spares MTAP-proficient tissue.
Methods: In vitro activity of AZ-PRMT5i-1 was profiled using six MTAP isogenic cell lines, as well as in a panel of 300 cancer cell lines. In vivo efficacy was assessed using three MTAP deleted models and hematological toxicity was addressed using a 3D human bone marrow model.
Results: Using a MTAP CRISPR KO isogenic pair we demonstrate potent inhibition of SDMA in MTAP-null tumors with a 54-fold margin over the MTAP wildtype (WT) counterpart. MTAP differential activity was maintained in proliferation assays across a number of MTAP isogenic cell lines and in a panel of 300 cancer cell lines. AZ-PRMT5i-1 demonstrates strong dose dependent efficacy across MTAP deleted xenograft and PDX models of gastric and lung origin, where greater than 80% of tumor growth inhibition was detected, with no apparent toxicity. In addition, corresponding dose-dependent inhibition of SDMA is observed in the treated tumors. In an in vitro 28-day 3D human bone marrow model, AZ-PRMT5i-1 has reduced toxicity in erythroid and megakaryocyte cell lineages, compared to a first generation PRMT5 inhibitor.
Conclusion: Overall, these studies demonstrate that AZ-PRMT5i-1 is a potent PRMT5 inhibitor demonstrating MTAP selectivity and anti-tumor activity in in vitro and in vivo pre-clinical models.

Introducing an Ethics Framework for health priority-setting in South Africa on the path to universal health coverage. S Afr Med J 2022; 112:240-244.

Abstract
BACKGROUND South Africa (SA) has embarked on a process to implement universal health coverage (UHC) funded by National Health Insurance (NHI). The 2019 NHI Bill proposes creation of a health technology assessment (HTA) body to inform decisions about which interventions NHI funds will cover under UHC. In practice, HTA often relies mainly on economic evaluations of cost-effectiveness and budget impact, with less attention to the systematic, specific consideration of important social, organisational and ethical impacts of the health technology in question. In this context, the South African Values and Ethics for Universal Health Coverage (SAVE-UHC) research project recognised an opportunity to help shape the health priority-setting process by providing a way to take account of multiple, ethically relevant considerations that reflect SA values. The SAVE-UHC Research Team developed and tested an SA-specific Ethics Framework for HTA assessment and analysis. OBJECTIVES To develop and test an Ethics Framework for use in the SA context for health priority-setting. METHODS The Framework was developed iteratively by the authors and a multidisciplinary panel (18 participants) over a period of 18 months, using the principles outlined in the 2015 NHI White Paper as a starting point. The provisional Ethics Framework was then tested with multi-stakeholder simulated appraisal committees (SACs) in three provinces. The membership of each SAC roughly reflected the composition of a potential SA HTA committee. The deliberations and dedicated focus group discussions after each SAC meeting were recorded, analysed and used to refine the Framework, which was presented to the Working Group for review, comment and final approval. RESULTS This article describes the 12 domains of the Framework. The first four (Burden of the Health Condition, Expected Health Benefits and Harms, Cost-Effectiveness Analysis, and Budget Impact) are commonly used in HTA assessments, and a further eight cover the other ethical domains. These are Equity, Respect and Dignity, Impacts on Personal Financial Situation, Forming and Maintaining Important Personal Relationships, Ease of Suffering, Impact on Safety and Security, Solidarity and Social Cohesion, and Systems Factors and Constraints. In each domain are questions and prompts to enable use of the Framework by both analysts and assessors. Issues that arose, such as weighting of the domains and the availability of SA evidence, were discussed by the SACs. CONCLUSIONS The Ethics Framework is intended for use in priority-setting within an HTA process. The Framework was well accepted by a diverse group of stakeholders. The final version will be a useful tool not only for HTA and other priority-setting processes in SA, but also for future efforts to create HTA methods in SA and elsewhere.

Abstract
There are many factors that contribute to the reproducibility and replicability of scientific research. There is a need to understand the research ecosystem, and improvements will require combined efforts across all parts of this ecosystem. National structures can play an important role in coordinating these efforts, working collaboratively with researchers, institutions, funders, publishers, learned societies and other sectoral organisations, and providing a monitoring and reporting function. Whilst many new ways of working and emerging innovations hold a great deal of promise, it will be important to invest in meta-research activity to ensure that these approaches are evidence based, work as intended, and do not have unintended consequences. Addressing reproducibility will require working collaboratively across the research ecosystem to share best practice and to make the most effective use of resources. The UK Reproducibility Network (UKRN) brings together Local Networks of researchers, Institutions, and External Stakeholders (funders, publishers, learned societies and other sectoral organisations), to coordinate action on reproducibility and work to ensure the UK retains its place as a centre for world-leading research. This activity is coordinated by the UKRN Steering Group. We consider this structure as valuable, bringing together a range of voices at a range of levels to support the combined efforts required to enact change.

Abstract
We report on a comparison between the theoretically predicted and experimentally measured spectra of the first-forbidden nonunique β-decay transition ^{137}Xe(7/2^{-})→^{137}Cs(7/2^{+}). The experimental data were acquired by the EXO-200 experiment during a deployment of an AmBe neutron source. The ultralow background environment of EXO-200, together with dedicated source deployment and analysis procedures, allowed for collection of a pure sample of the decays, with an estimated signal to background ratio of more than 99 to 1 in the energy range from 1075 to 4175 keV. In addition to providing a rare and accurate measurement of the first-forbidden nonunique β-decay shape, this work constitutes a novel test of the calculated electron spectral shapes in the context of the reactor antineutrino anomaly and spectral bump.

Abstract
A search for neutrinoless double-β decay (0νββ) in ^{136}Xe is performed with the full EXO-200 dataset using a deep neural network to discriminate between 0νββ and background events. Relative to previous analyses, the signal detection efficiency has been raised from 80.8% to 96.4±3.0%, and the energy resolution of the detector at the Q value of ^{136}Xe 0νββ has been improved from σ/E=1.23% to 1.15±0.02% with the upgraded detector. Accounting for the new data, the median 90% confidence level 0νββ half-life sensitivity for this analysis is 5.0×10^{25} yr with a total ^{136}Xe exposure of 234.1 kg yr. No statistically significant evidence for 0νββ is observed, leading to a lower limit on the 0νββ half-life of 3.5×10^{25} yr at the 90% confidence level.

Abstract
An auditory illusion caught the world's attention recently. For the same noisy speech utterance, different people reported hearing either 'Laurel' or 'Yanny'. The dichotomy highlights how perceptions are inferences from inherently ambiguous sensory information, even though ambiguity is often unnoticed.

Abstract
Despite its potential to accelerate academic progress in psychological science, public data sharing remains relatively uncommon. In order to discover the perceived barriers to public data sharing and possible means for lowering them, we conducted a survey, which elicited responses from 600 authors of articles in psychology. The results confirmed that data are shared only infrequently. Perceived barriers included respondents’ belief that sharing is not a common practice in their fields, their preference to share data only upon request, their perception that sharing requires extra work, and their lack of training in sharing data. Our survey suggests that strong encouragement from institutions, journals, and funders will be particularly effective in overcoming these barriers, in combination with educational materials that demonstrate where and how data can be shared effectively.

Abstract
BACKGROUND Clinical trials have not yet compared the efficacy of capsaicin 8% patch with current standard therapy in peripheral neuropathic pain (PNP). OBJECTIVES Head-to-head efficacy and safety trial comparing the capsaicin patch with pregabalin in PNP. METHODS Open-label, randomized, multicentre, non-inferiority trial. Patients with PNP, aged 18-80 years, were randomly assigned to either the capsaicin 8% patch (n = 282) or an optimised dose of oral pregabalin (n = 277), and assessed for a ≥30% mean decrease in Numeric Pain Rating Scale (NPRS) score from baseline to Week 8. Secondary endpoints included optimal therapeutic effect (OTE), time-to-onset of pain relief and treatment satisfaction. RESULTS The capsaicin 8% patch was non-inferior to pregabalin in achievement of a ≥30% mean decrease in NPRS score from baseline to Week 8 (55.7% vs. 54.5%, respectively; Odds ratio: 1.03 [95% CI: 0.72, 1.50]). The proportion of patients achieving OTE at Week 8 was 52.1% for the capsaicin 8% patch versus 44.8% for pregabalin (difference: 7.3%; 95% CI: -0.9%, 15.6%). The median time-to-onset of pain relief was significantly shorter for capsaicin 8% patch versus pregabalin (7.5 vs. 36.0 days; Hazard ratio: 1.68 [95% CI: 1.35, 2.08]; p < 0.0001). Treatment satisfaction was also significantly greater with the capsaicin 8% patch versus pregabalin. TEAEs were mild-to-moderate in severity, and resulted in treatment discontinuation only with pregabalin (n = 24). Systemic adverse drug reactions ranged from 0 to 1.1% with capsaicin 8% patch and 2.5 to 18.4% with pregabalin. CONCLUSIONS The capsaicin 8% patch provided non-inferior pain relief to an optimized dose of pregabalin in PNP, with a faster onset of action, fewer systemic side effects and greater treatment satisfaction.

Abstract
We describe a system to transport and identify barium ions produced in liquid xenon, as part of R&D towards the second phase of a double beta decay experiment, nEXO. The goal is to identify the Ba ion resulting from an extremely rare nuclear decay of the isotope (136)Xe, hence providing a confirmation of the occurrence of the decay. This is achieved through Resonance Ionization Spectroscopy (RIS). In the test setup described here, Ba ions can be produced in liquid xenon or vacuum and collected on a clean substrate. This substrate is then removed to an analysis chamber under vacuum, where laser-induced thermal desorption and RIS are used with time-of-flight mass spectroscopy for positive identification of the barium decay product.

Abstract
The 2013/14 influenza season to date in Canada has been characterised by predominant (90%) A(H1N1)pdm09 activity. Vaccine effectiveness (VE) was assessed in January 2014 by Canada's sentinel surveillance network using a test-negative case-control design. Interim adjusted-VE against medically-attended laboratory-confirmed influenza A(H1N1)pdm09 infection was 74% (95% CI: 58-83). Relative to vaccine, A(H1N1)pdm09 viruses were antigenically similar and genetically well conserved, with most showing just three mutations across the 50 amino acids comprising antigenic sites of the haemagglutinin protein.

Abstract
BACKGROUND There is conflicting literature on the effect of maternal asthma on congenital malformations and neonatal outcomes. OBJECTIVES This review and meta-analysis sought to determine if maternal asthma is associated with an increased risk of adverse neonatal outcomes. SEARCH STRATEGY We searched electronic databases for: (asthma or wheeze) and (pregnan* or perinat* or obstet*). SELECTION CRITERIA Cohort studies published between 1975 and March 2012 reporting at least one perinatal outcome of interest (congenital malformations, neonatal complications, perinatal mortality). DATA COLLECTION AND ANALYSIS In all, 21 studies met inclusion criteria in pregnant women with and without asthma. Further analysis was conducted on 16 studies where asthmatic women were stratified by exacerbation history, corticosteroid use, bronchodilator use or asthma severity. MAIN RESULTS Maternal asthma was associated with a significantly increased risk of congenital malformations (relative risk [RR] 1.11, 95% confidence interval [95% CI] 1.02-1.21, I(2) = 59.5%), cleft lip with or without cleft palate (RR 1.30, 95% CI 1.01-1.68, I(2) = 65.6%), neonatal death (RR 1.49, 95% CI 1.11-2.00, I(2) = 0%), and neonatal hospitalisation (RR 1.50, 95% CI 1.03-2.20, I(2) = 64.5%). There was no significant effect of asthma on major malformations (RR 1.31, 95% CI 0.57-3.02, I(2) = 70.9%) or stillbirth (RR 1.06, 95% CI 0.9-1.25, I(2) = 35%). Exacerbations and use of bronchodilators and inhaled corticosteroids were not associated with congenital malformation risk. AUTHORS' CONCLUSIONS Despite limitations related to the observational nature of the primary studies, this review demonstrates a small increased risk of neonatal complications among pregnant women with asthma. Further investigations into mechanisms and potential preventive interventions to improve infant outcomes are required.

Abstract
The context in which a stimulus occurs can influence its perception. We study contextual effects in audition using the tritone paradox, where a pair of complex (Shepard) tones separated by half an octave can be perceived as ascending or descending. While ambiguous in isolation, they are heard with a clear upward or downward change in pitch, when preceded by spectrally matched biasing sequences. We presented these biased Shepard pairs to awake ferrets and obtained neuronal responses from primary auditory cortex. Using dimensionality reduction from the neural population response, we decode the perceived pitch for each tone. The bias sequence is found to reliably shift the perceived pitch of the tones away from its central frequency. Using human psychophysics, we provide evidence that this shift in pitch is present in active human perception as well. These results are incompatible with the standard absolute distance decoder for Shepard tones, which would have predicted the bias to attract the tones. We propose a relative decoder that takes the stimulus history into account and is consistent with the present and other data sets.

Abstract
The software used by organizations can have a substantial effect on employees’ productivity. One of the dominant kinds of software in the workplace today is the spreadsheet, which has proven useful for performing numeric computations as well as for organizing, manipulating, and visualizing data. The authors present an analysis of the problems reported online by users of different spreadsheet editors, in order to guide the selection and enhancement of those editors. They’ve found that most requests for help were related to operations that the authors refer to as “foundational,” such as with configuring the editor and setting up real-world problems in the form of spreadsheets, rather than with using particular formulas or features. They have identified a number of key similarities and differences in questions about different spreadsheet editors and versions of Excel, ultimately leading to several challenging opportunities for future research.

Abstract
BACKGROUND Asthma is a common condition during pregnancy and may be associated with adverse perinatal outcomes. OBJECTIVE This meta-analysis sought to establish if maternal asthma is associated with an increased risk of adverse perinatal outcomes, and to determine the size of these effects. SEARCH STRATEGY Electronic databases were searched for the following terms: (asthma or wheeze) and (pregnan* or perinat* or obstet*). SELECTION CRITERIA Cohort studies published between 1975 and March 2009 were considered for inclusion. Studies were included if they reported at least one perinatal outcome in pregnant women with and without asthma. DATA COLLECTION AND ANALYSIS A total of 103 articles were identified, and of these 40 publications involving 1,637,180 subjects were included. Meta-analysis was conducted with subgroup analyses by study design and active asthma management. MAIN RESULTS Maternal asthma was associated with an increased risk of low birthweight (RR 1.46, 95% CI 1.22-1.75), small for gestational age (RR 1.22, 95% CI 1.14-1.31), preterm delivery (RR 1.41, 95% CI 1.22-1.61) and pre-eclampsia (RR 1.54, 95% CI 1.32-1.81). The relative risk of preterm delivery and preterm labour were reduced to non-significant levels by active asthma management (RR 1.07, 95% CI 0.91-1.26 for preterm delivery; RR 0.96, 95% CI 0.73-1.26 for preterm labour). AUTHOR'S CONCLUSIONS Pregnant women with asthma are at increased risk of perinatal complications, including pre-eclampsia and outcomes that affect the baby's size and timing of birth. Active asthma management with a view to reducing the exacerbation rate may be clinically useful in reducing the risk of perinatal complications, particularly preterm delivery.

Abstract
OBJECTIVE A systematic review and meta-analysis was conducted to determine the efficacy and tolerability of tacrolimus ointment for the treatment of atopic dermatitis (AD) compared with topical corticosteroids. METHODS Electronic searches were performed in Medline, Embase and the Cochrane Library, as well as relevant conference proceedings. Two researchers independently selected trials investigating the efficacy and/or safety of tacrolimus ointment in the treatment of AD. No language restrictions were applied. Relevant outcome data from included trials were extracted by two independent reviewers. Direct meta-analysis to calculate relative risks (RR) (95% confidence intervals (CIs)) was conducted on dichotomous efficacy/safety outcomes of interest. RESULTS Seventeen trials comparing tacrolimus ointment with topical corticosteroids in both paediatric (n = 2328) and adult (n = 2849) patients were identified. No studies comparing tacrolimus ointment with class IV topical corticosteroids were identified. Tacrolimus 0.1% ointment was found to be of similar efficacy to class I/II and class III topical corticosteroids. In three individual trials (comparing tacrolimus 0.1% ointment to a topical corticosteroid), evaluation of the Physician's Global Evaluation of Clinical Response (PGECR) resulted in RRs of 0.95 (95% CI 0.78-1.16), 3.09 (95% CI 2.14-4.45) and 1.35 (95% CI 0.86-2.12), where values above one favour tacrolimus ointment. With the exception that tacrolimus ointment caused more skin burning than comparator treatments (tacrolimus 0.03% versus a class III topical corticosteroid, the RR was 3.00 (95% CI 1.21-7.43) in favour of the corticosteroid), no significant differences with regards to side-effects and withdrawals due to AEs were found. Quality of life data were reported in two studies. While one study reported greater improvements in tacrolimus-treated adult patients compared with topical steroids, the second reported greater improvements in paediatric patients treated with steroids compared with tacrolimus ointment. CONCLUSIONS The current review and meta-analysis showed tacrolimus ointment to be of similar efficacy to corticosteroids. The interpretation of available data is limited by heterogeneity in outcome measures between trials. Further trials are needed to assess the impact of treatments on patient reported outcomes.

Abstract
PURPOSE Bone metastases are the most common cause of cancer pain, with palliative radiotherapy (RT) the mainstay of treatment. However, relief from RT may be delayed, incomplete, or short-lived and therefore optimized pharmacologic therapy is essential. Our objective was to describe the contribution of the clinical pharmacist (CP) to an outpatient palliative RT clinic. METHODS The Edmonton Symptom Assessment System, an 11-point scale for measuring nine symptoms, and other validated screening tools were administered, and a medication history performed by the CP. Baseline CP assessment also included opioid toxicity, need for supportive medications, and drug interactions. Anonymized clinical information was collected prospectively and descriptive statistics were compiled including themes of counselling performed by the CP. RESULTS The CP reviewed 114 patients over 140 clinic visits (01/2007-12/2008). Median age was 68.3 years, 68.4% were male and 36.8% had prostate cancer. All symptoms improved or stabilized in ≥ 80% by 4 weeks. Median pain score was 6/10 (SD 2.6) at baseline, and 2.1/10 (SD 2.4) by week 4. Average morphine equivalent daily dose was 76.8 mg at baseline and 44.5 mg at week 4. CP assessment included screening for opioid toxicity (87.9%), recommending a change in analgesic (28.9%), and liaison with the community pharmacy (17.1%). Medication counselling took place in 84.3% of visits, on bowel routine (85.6% of the time), opioids (82.2%), and hydration (40.7%). CONCLUSIONS The CP plays a key role in holistic patient assessment and optimization of pharmacologic therapy, contributing to improved symptom control of patients receiving palliative RT.
