Coronary heart disease (CHD) risk in 20 non-diabetic women with and 20 without a distant history of gestational diabetes (hGDM), matched on age, body mass index, and time since GDM-affected pregnancy, was compared in a case control study. Women with an hGDM had lower high-density lipoprotein cholesterol (HDL-c), p = .02, and higher triglycerides, p < or = .001, versus controls. The combination of high triglycerides and low HDL-c occurred in 25% of hGDM cases versus 0% of controls, p

Objective: To investigate whether L-isoleucine was effective in the treatment of hot flushes and whether L-isoleucine, L-valine, or the combination of both amino acids reduced fasting serum homocysteine.Methods: After a 1-week baseline period, 100 postmenopausal women experiencing at least five moderate-severe hot flushes per day were randomized with equal probability to one of four groups (phase 1/phase 2): placebo/L-valine, placebo/L-valine and L-isoleucine, L-isoleucine/L-valine, and L-isoleucine/L-valine and L-isoleucine. Phase 1 was 12 weeks long, and phase 2 was 10 weeks long. Patients took five capsules by mouth, twice a day throughout the study, with each capsule containing 500 mg of compound. Data were obtained from daily hot flush diaries, fasting blood work, and several questionnaires. The primary outcome variable was the percent change in hot flush composite score from baseline to week 12.Results: In phase 1 of the study, there were no significant differences between the L-isoleucine and placebo groups for any of the outcome measures. At week 12, there was a mean 13.9% decrease in hot flush composite score compared with baseline in the L-isoleucine group and a mean 25% decrease in the placebo group (P=.28). In phase 2 of the study, there was no significant change in fasting serum homocysteine levels associated with any of the amino acid therapies.Conclusion: L-isoleucine therapy appears to be ineffective in the treatment of hot flushes in postmenopausal women. L-isoleucine and L-valine, either alone or in combination, appear to have no effect on fasting serum homocysteine levels.

Although both human herpesvirus (HHV) 6 and HHV-7 infections are ubiquitous during childhood, few acute HHV-7 infections are identified. It is unknown whether HHV-7 viremia indicates primary infection, as with HHV-6, or reactivation, and if these differ clinically. We studied, in otherwise healthy children

Background: Risk stratification for comparison of outcomes after coronary artery bypass grafting (CABG) typically includes only clinical measures of risk. Patient-reported health status may be an important independent predictor of short-term health outcomes.Objective: To determine whether patient-reported health status, as measured by the Physical and Mental Component Summary scores of the SF-36, predicts in-hospital mortality and prolonged length of stay after CABG, after controlling for other clinical predictors of those outcomes.Research Design: Prospective cohort study conducted from September 1993 to November 1995.Subjects: One thousand seven hundred seventy-eight adults who underwent isolated CABG for myocardial ischemia.Measures: In-hospital mortality and prolonged length of stay (> 14 days).Results: There were 27 deaths and 223 patients with prolonged length of stay in the study sample. A 10-point decrease in the Physical Component Summary (PCS) score increased the odds of in-hospital mortality by 61% (OR, 1.61; 95% CI, 1.04-2.49), independent of established clinical risk factors. Similarly, a 10-point decrease in the PCS score increased the odds of prolonged length of stay by 33% (OR, 1.33; 95% CI, 1.13-1.57). A 10-point decrease in the Mental Component Summary score (MCS) decreased the odds of mortality by 36% (OR, 0.64; 95% CI, 0.43-0.95).Conclusions: The PCS score is independently and significantly associated with in-hospital mortality and prolonged length of stay, after controlling for clinical risk factors. The MCS score is independently and significantly associated only with mortality, though the direction of the effect is unexpected. The result likely reflects a property of the scoring of the MCS and not a finding of clinical substance. Although caution must be taken when interpreting the summary scores, the SF-36 yields information not otherwise captured by clinical data and may be useful in risk stratification for in-hospital mortality and prolonged length of stay after CABG.

Selecting an outcomes assessment instrument requires knowledge of their relative merits, especially head-to-head comparisons. The authors compare health-related quality-of-life (HRQOL) instruments among older adults for their psychometric properties and subject burden, specifically the Sickness Impact Profile (SIP) and Medical Outcomes Study Short-Form 36 (SF-36). Subjects were 282 of 373 eligible older adults (75.6% response) ranging in age from 65 to 96. SIP scores demonstrated a strong skew toward low (good health) scores with a mean of 11.1% (+/- SD 11.5) on the Total SIP index score. Similar components of the SIP and SF-36 were moderately to strongly correlated. The SIP suffered from a ceiling (good health) scaling effect, and the SF-36 scales also demonstrated some scaling extremes. These results demonstrate the relative scaling limits, especially the ceiling effect, of the SIP compared to the SF-36, and in general, the SF-36 is preferred for use among community-living older adults.

Objective: To examine the safety and tolerability of clonidine used alone or with methylphenidate in children with attention-deficit/hyperactivity disorder (ADHD).Method: In a 16-week multicenter, double-blind trial, 122 children with ADHD were randomly assigned to clonidine (n = 31), methylphenidate (n = 29), clonidine and methylphenidate (n = 32), or placebo (n = 30). Doses were flexibly titrated up to 0.6 mg/day for clonidine and 60 mg/day for methylphenidate (both with divided dosing). Groups were compared regarding adverse events and changes from baseline to week 16 in electrocardiograms and vital signs.Results: There were more incidents of bradycardia in subjects treated with clonidine compared with those not treated with clonidine (17.5% versus 3.4%; p =.02), but no other significant group differences regarding electrocardiogram and other cardiovascular outcomes. There were no suggestions of interactions between clonidine and methylphenidate regarding cardiovascular outcomes. Moderate or severe adverse events were more common in subjects on clonidine (79.4% versus 49.2%; p =.0006) but not associated with higher rates of early study withdrawal. Drowsiness was common on clonidine, but generally resolved by 6 to 8 weeks.Conclusions: Clonidine, used alone or with methylphenidate, appears safe and well tolerated in childhood ADHD. Physicians prescribing clonidine should monitor for bradycardia and advise patients about the high likelihood of initial drowsiness. [ABSTRACT FROM AUTHOR]

Background and Aims: The Charcot-Marie-Tooth Disease Health Index (CMT-HI) is a disease-specific, patient-reported disease burden measure. As part of an international clinical trial readiness study, individuals with CMT1A (ages 18-75 years) underwent clinical outcome assessments (COAs), including the CMT-HI, to capture their longitudinal perspective on the disease burden., Methods: Two hundred and fifteen participants underwent serial COAs including the CMT-HI, CMT Functional Outcome Measure (CMT-FOM), CMT Neuropathy Score (CMTNSv2R), and CMT Exam Score (CMTES/CMTES-R). Correlations between the total and subscale scores for the CMT-HI and other COAs were determined. Changes in the CMT-HI scores over 12 months were assessed using paired t-tests. The minimum clinically important difference (MCID) for the CMT-HI and its subscales were calculated by anchoring to a participant global impression of change scale., Results: At baseline, CMT1A participants were 44.5 ± 15 years old (range: 18-75) and 58% were women. The mean CMT-HI was 25.7 ± 18.8 (range: 0-91.9; 100 reflecting maximal disease burden). The CMT-HI correlated with the CMT-FOM (r = .54, p < .0001), CMTNSv2R (r = .48, p < .0001), and CMTES/CMTES-R (r = .52/r = .54, p < .0001). Disease burden was greater in women than in men (CMT-HI 29.1 ± 19.1 vs. 21.2 ± 17.3, p = .001). Over 12 months, there was a nonsignificant mean increase in CMT-HI of 0.40 ± 10.0 (n = 189, p = .89). The MCID for the CMT-HI total score was 3.8 points (95% CI: 1.7-5.9)., Discussion: Patient-reported disease burden in CMT1A as measured by the CMT-HI is associated with measures of neurologic impairment and physical functioning. Women reported a higher disease burden than men. These data will inform the design of clinical trials in CMT1A., (© 2024 Peripheral Nerve Society.)

Objective: To explore the clinical relevance and assay sensitivity of using personalized outcomes using data from a randomized clinical trial (RCT) in people with chemotherapy induced peripheral neuropathy (CIPN)., Design: This study is a secondary analysis that leveraged data from a RCT of transcutaneous electrical stimulation for CIPN to test whether personalized outcomes could minimize potential floor effects and increase the assay sensitivity of pain clinical trials (ie, ability to detect a true treatment effect)., Setting: Participants were recruited for a RCT from community oncology clinics in the U.S., Participants: Adults with CIPN (N = 72) who reported on average ≥4 intensity (measured via a 7-day baseline diary) for at least one of the following pain qualities hot/burning pain, sharp/shooting pain and/or cramping., Methods: Personalized outcomes were defined based on participants' unique presentation of pain qualities at baseline, measured via 0-10 numeric rating scales (NRS), or ranking of the distress caused by the pain qualities. Analysis of covariance models estimated the treatment effect as measured by personalized and non-personalized outcomes., Results: The adjusted mean difference between groups was higher using personalized outcomes (ie, 1.21-1.25 NRS points) compared to a non-personalized outcome (ie, 0.97 NRS points), although the standardized effect sizes were similar between outcomes (0.49-0.54)., Conclusions: These results suggest that personalized pain quality outcomes could minimize floor effects, while providing similar assay sensitivity to non-personalized pain quality outcomes. Personalized outcomes better reflect an individual's unique experience, inherently providing more clinically relevant estimates of treatment effects. Personalized outcomes may be advantageous particularly for clinical trials in populations with high inter-individual variability in pain qualities., (© The Author(s) 2024.

Background: Non-dystrophic myotonias are skeletal muscle channelopathies caused by ion channel dysfunction. Symptom onset is frequently in the first decade of life, causing disability in a young cohort. Although there is no cure, symptomatic treatments exist. Previous trials provide evidence of the efficacy of mexiletine. More recently, lamotrigine has been shown to be effective. Both treatments have different profiles, including pharmacokinetics and adverse events. This trial aimed to investigate whether lamotrigine is non-inferior to mexiletine to directly inform clinical practice., Methods: We did a randomised, double-blind, crossover, non-inferiority, phase 3 trial at the National Hospital for Neurology and Neurosurgery (London, UK). Participants (aged ≥18 years) who had genetically confirmed symptomatic non-dystrophic myotonia were randomly assigned (1:1), by means of a block randomisation schedule created by a computer program, to receive either mexiletine for 8 weeks followed by lamotrigine for 8 weeks, or lamotrigine followed by mexiletine, with a 7-day washout period in between. Investigators and participants were masked to treatment allocation. The primary outcome measure was the mean interactive voice response (IVR) diary stiffness score (0-9 scale) over the participant's final 2 weeks of diary reporting in each treatment period. Non-inferiority was assessed using a mixed-effects model with a predefined margin of 0·5 and included all randomly assigned participants who contributed at least 7 days of IVR-diary data in either treatment period. The trial is registered at ClinicalTrials.gov, NCT05017155, and EudraCT, 2020-003375-17., Findings: Between Aug 1, 2021, and Dec 12, 2022, of 60 participants were screened (24 females and 36 males) and randomly assigned between Aug 1, 2021 and Dec 12, 2022, to either the mexiletine-lamotrigine sequence (n=30) or the lamotrigine-mexiletine sequence (n=30). 53 participants contributed data to the primary analysis. The mean IVR stiffness score after treatment with mexiletine was 2·54 (95% CI 1·98 to 3·10) versus 2·77 (2·21 to 3·32) with lamotrigine (mean mexiletine-lamotrigine difference -0·23 [95% CI -0·63 to 0·17]). The most common adverse event with both treatments was indigestion-reflux (eight participants, 208 participant-days receiving mexiletine; seven participants, 130 participant-days receiving lamotrigine). No serious adverse events were reported., Interpretation: We were unable to conclude that lamotrigine is non-inferior to mexiletine; however, improvements in all outcome measures from baseline were similar between lamotrigine and mexiletine. Lamotrigine is an important treatment consideration in non-dystrophic myotonias alongside mexiletine; we propose a treatment algorithm to guide clinical practice., Funding: Neuromuscular Study Group, Jon Moulton Charity Trust, UCLH BRC Fast Track Grant., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 The Author(s).

Abstract: Pragmatic, randomized, controlled trials hold the potential to directly inform clinical decision making and health policy regarding the treatment of people experiencing pain. Pragmatic trials are designed to replicate or are embedded within routine clinical care and are increasingly valued to bridge the gap between trial research and clinical practice, especially in multidimensional conditions, such as pain and in nonpharmacological intervention research. To maximize the potential of pragmatic trials in pain research, the careful consideration of each methodological decision is required. Trials aligned with routine practice pose several challenges, such as determining and enrolling appropriate study participants, deciding on the appropriate level of flexibility in treatment delivery, integrating information on concomitant treatments and adherence, and choosing comparator conditions and outcome measures. Ensuring data quality in real-world clinical settings is another challenging goal. Furthermore, current trials in the field would benefit from analysis methods that allow for a differentiated understanding of effects across patient subgroups and improved reporting of methods and context, which is required to assess the generalizability of findings. At the same time, a range of novel methodological approaches provide opportunities for enhanced efficiency and relevance of pragmatic trials to stakeholders and clinical decision making. In this study, best-practice considerations for these and other concerns in pragmatic trials of pain treatments are offered and a number of promising solutions discussed. The basis of these recommendations was an Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) meeting organized by the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks., (Copyright © 2024 The Author(s).

Importance: A third of children who survive malaria with neurological involvement (central nervous system [CNS] malaria) develop sequelae. A higher maximum temperature (Tmax) and seizures are risk factors for sequelae., Objective: To compare aggressive antipyretic therapy using scheduled acetaminophen and ibuprofen vs usual care with acetaminophen alone given only for a temperature of 38.5 °C or higher., Design, Setting, and Participants: This randomized clinical trial was conducted at inpatient pediatric services of 1 tertiary care and 1 district hospital in Zambia and a tertiary care center in Malawi. Included were children aged 2 to 11 years with CNS malaria (excluding those with creatinine >1.2 mg/dL), who were enrolled from 2019 to 2022. Data analysis took place from December 2022 to April 2023., Intervention: The aggressive antipyretic group received acetaminophen (30 mg/kg load, then 15 mg/kg) plus ibuprofen, 10 mg/kg, every 6 hours, regardless of clinical temperature for 72 hours. The usual care group received 15 mg/kg of acetaminophen as needed every 6 hours for a temperature of 38.5 °C or higher., Main Outcomes and Measures: The primary outcome variable was Tmax over 72 hours, the total duration of follow-up. Secondary outcomes included seizures and parasite clearance., Results: Five hundred fifty-three patients were screened, 226 (40.9%) were ineligible, and 57 (10.3%) declined. A total 256 participants (n = 128/group) had a mean (SD) age of 4.3 (2.1) years; 115 (45%) were female, and 141 (55%) were male. The aggressive antipyretic group had a lower Tmax, 38.6 vs 39.2 °C (difference, -0.62 °C; 95% CI, -0.82 to -0.42; P < .001) and lower odds of experiencing multiple or prolonged seizures, 10 (8%) vs 34 children (27%) in the usual care group (odds ratio [OR], 0.26; 95% CI, 0.12 to 0.56). No group difference in parasite clearance time was detected. Severe adverse events occurred in 40 children (15%), 25 (20%) in the usual care group and 15 (12%) in the aggressive antipyretic group, including 13 deaths (10 [8%] and 3 [2%], respectively). Increased creatinine resulted in study drug discontinuation in 8 children (6%) in the usual care group and 13 children (10%) in the aggressive antipyretic group (OR, 1.74; 95% CI, 0.63 to 5.07)., Conclusions and Relevance: This study found that aggressive antipyretic therapy reduced mean Tmax to temperature levels comparable with the Tmax among children without neurological impairments in prior observational studies and improved acute seizure outcomes with no prolongation of parasitemia., Trial Registration: ClinicalTrials.gov Identifier: NCT03399318.

Increasing appreciation of the phenotypic and biological overlap between amyotrophic lateral sclerosis (ALS) and frontotemporal dementia, alongside evolving biomarker evidence for a pre-symptomatic stage of disease and observations that this stage of disease might not always be clinically silent, is challenging traditional views of these disorders. These advances have highlighted the need to adapt ingrained notions of these clinical syndromes to include both the full phenotypic continuum - from clinically silent, to prodromal, to clinically manifest - and the expanded phenotypic spectrum that includes ALS, frontotemporal dementia and some movement disorders. The updated clinical paradigms should also align with our understanding of the biology of these disorders, reflected in measurable biomarkers. The Miami Framework, emerging from discussions at the Second International Pre-Symptomatic ALS Workshop in Miami (February 2023; a full list of attendees and their affiliations appears in the Supplementary Information) proposes a classification system built on: first, three parallel phenotypic axes - motor neuron, frontotemporal and extrapyramidal - rather than the unitary approach of combining all phenotypic elements into a single clinical entity; and second, biomarkers that reflect different aspects of the underlying pathology and biology of neurodegeneration. This framework decouples clinical syndromes from biomarker evidence of disease and builds on experiences from other neurodegenerative diseases to offer a unified approach to specifying the pleiotropic clinical manifestations of disease and describing the trajectory of emergent biomarkers., (© 2024.

Background and Objectives: Clinical trials in Duchenne muscular dystrophy (DMD) require 3-6 months of stable glucocorticoids, and the primary outcome is explored at 48-52 weeks. The factors that influence the clinical outcome assessment (COA) trajectories soon after glucocorticoid initiation are relevant for the design and analysis of clinical trials of novel drugs. We describe early COA trajectories, associated factors, and the time from glucocorticoid initiation to COA peak., Methods: This was a prospective 18-month analysis of the Finding the Optimum Corticosteroid Regimen for Duchenne Muscular Dystrophy study. Four COAs were investigated: rise from supine velocity (RFV), 10-meter walk/run velocity (10MWRV), North Star Ambulatory Assessment (NSAA) total score, and 6-minute walk test distance (6MWT). The relationships of baseline age (4-5 vs 6-7 years), COA baseline performance, genotype, and glucocorticoid regimen (daily vs intermittent) with the COA trajectories were evaluated using linear mixed-effects models., Results: One hundred ninety-six glucocorticoid-naïve boys with DMD aged 4-7 years were enrolled. The mean age at baseline was 5.9 ± 1.0 years, 66% (n = 130) were on daily regimens, 55% (n = 107) showed a 6MWT distance >330 metres; 41% (n = 78) showed RFV >0.2 rise/s; 76% (n = 149) showed 10MWRV >0.142 10m/s, and 41.0% (n = 79) showed NSAA total score >22 points. Mean COA trajectories differed by age at glucocorticoid initiation ( p < 0.01 for RFV, 10MWRV, and NSAA; p < 0.05 for 6MWT) and regimen ( p < 0.01 for RFV, 10MWRV, and NSAA). Boys younger than 6 years reached their peak performance 12-18 months after glucocorticoid initiation. Boys aged 6 years or older on a daily regimen peaked between months 9 and 12 and those on an intermittent regimen by 9 months. The baseline COA performance was associated with the NSAA ( p < 0.01) and the 6MWT trajectory in boys younger than 6 years on a daily regimen ( p < 0.01). Differences in the mean trajectories by genotype were not significant., Discussion: Glucocorticoid regimen, age, duration of glucocorticoid exposure, and baseline COA performance need to be considered in the design and analysis of clinical trials in young boys with DMD.

Background: Randomized clinical trials (RCTs) generally assess efficacy and safety separately, with the conclusion of whether a treatment is beneficial based solely on the efficacy endpoint. However, assessing and combining efficacy and safety domains, using a single composite outcome measure, can provide a more comprehensive assessment of the overall effect of a treatment. Furthermore, composite outcomes can incorporate information regarding the relationship between the individual outcomes. In fact, such outcomes have been suggested in the clinical trials literature for at least 15 years., Objectives: To (1) identify whether recent primary publications of chronic pain RCTs from major pain journals included a composite outcome measure of benefits and harms and (2) discuss the potential benefits of such outcomes in various stages of treatment development, including as outcome measures in RCTs, and to support decisions of Data and Safety Monitoring Boards and ordering of treatments in the context of treatment guidelines., Evidence Review: RCTs published in 6 major pain journals published between 2016 and 2021 that investigated interventions for chronic pain were reviewed., Findings: Of 73 RCTs identified, only 2 included a composite outcome measure of benefits and harms. Both of these articles compared 2 active treatments., Conclusions: Composite outcomes of benefits and harms are underutilized in chronic pain RCTs. The advantages and challenges of using such outcomes are discussed., Competing Interests: Competing interests: RHD has received in the past 5 years research grants and contracts from the US Food and Drug Administration and the US National Institutes of Health, and compensation for serving on advisory boards or consulting on clinical trial methods from Abide, Acadia, Adynxx, Analgesic Solutions, Aptinyx, Aquinox, Asahi Kasei, Astellas, Beckley, Biogen, Biohaven, Biosplice, Boston Scientific, Braeburn, Cardialen, Centrexion, Chiesi, Chromocell, Clexio, Collegium, CoimbiGene, Confo, Decibel, Editas, Eli Lilly, Endo, Ethismos (equity), Eupraxia, Exicure, GlaxoSmithKline, Glenmark, Gloriana, Hope, Kriya, Lotus, Mainstay, Merck, Mind Medicine (also equity), Neumentum, Neurana, NeuroBo, Novaremed, Novartis, OliPass, Orion, Oxford Cannabinoid Technologies, Pfizer, Q-State, Reckitt Benckiser, Regenacy (also equity), Rho, Sangamo, Sanifit, Scilex, Semnur, SIMR Biotech, Sinfonia, SK Biopharmaceuticals, Sollis, SPM Therapeutics SPRIM, Teva, Theranexus, Vertex, Vizuri, and WCG.

Aim: To investigate functional motor performance in a large cohort of young steroid-naïve males with Duchenne muscular dystrophy (DMD) and typically developing males, and to develop specific reference curves for both groups. Also, to describe associations between anthropometric values and functional motor outcomes., Method: Cross-sectional data of 196 steroid-naïve males with DMD aged 4 to 8 years and 497 typically developing males aged 2 years 6 months to 8 years were included. Both groups were evaluated with the time to rise from the floor test, 10-metre walk/run test, 6-minute walk test, and North Star Ambulatory Assessment. Reference curves with centiles 5%, 10%, 25%, 50%, 75%, 90%, and 95% were estimated using quantile regression., Results: Males with DMD scored significantly worse on all functional motor outcomes than age-matched typically developing males (p < 0.001): 89% to 95% of the males with DMD scored below the 5th centile of the typically developing males. No or weak correlations exist between anthropometric values and functional motor outcomes., Interpretation: The estimated reference curves can support consultation with families of young males with DMD and can support the evaluation of treatment for reaching motor skills and functional motor outcomes compared with typically developing males., (© 2023 Mac Keith Press.)

Background: The natural history of spinal muscular atrophy (SMA) is well understood, with progressive muscle weakness resulting in declines in function. The development of contractures is common and negatively impacts function. Clinically, joint hypermobility (JH) is observed but is poorly described, and its relationship with function is unknown. Methods : Lower-limb ROM (range of motion) assessments of extension and flexion at the hip, knee, and ankle were performed. ROMs exceeding the published norms were included in the analysis. The functional assessments performed included the six-minute walk test (6 MWT) and the Hammersmith Functional Motor Scale-Expanded (HFMSE). Results: Of the 143 participants, 86% ( n = 123) had at least one ROM measure that was hypermobile, and 22% ( n = 32) had three or more. The HFMSE scores were inversely correlated with hip extension JH (r = -0.60, p = 0.21; n = 6) and positively correlated with knee flexion JH (r = 0.24, p = 0.02, n = 89). There was a moderate, inverse relationship between the 6 MWT distance and ankle plantar flexion JH (r = -0.73, p = 0.002; n = 15). Conclusions: JH was identified in nearly all participants in at least one joint in this study. Hip extension, knee flexion and ankle plantar flexion JH was associated with function. A further understanding of the trajectory of lower-limb joint ROM is needed to improve future rehabilitation strategies.

Background: Despite eradication efforts, ~135,000 African children sustained brain injuries as a result of central nervous system (CNS) malaria in 2021. Newer antimalarial medications rapidly clear peripheral parasitemia and improve survival, but mortality remains high with no associated decline in post-malaria neurologic injury. A randomized controlled trial of aggressive antipyretic therapy with acetaminophen and ibuprofen (Fever RCT) for malarial fevers being conducted in Malawi and Zambia began enrollment in 2019. We propose to use neuroimaging in the context of the RCT to further evaluate neuroprotective effects of aggressive antipyretic therapy., Methods: This observational magnetic resonance imaging (MRI) ancillary study will obtain neuroimaging and neurodevelopmental and behavioral outcomes in children previously enrolled in the Fever RCT at 1- and 12-months post discharge. Analysis will compare the odds of any brain injury between the aggressive antipyretic therapy and usual care groups based upon MRI structural abnormalities. For children unable to undergo imaging without deep sedation, neurodevelopmental and behavioral outcomes will be used to identify brain injury., Discussion: Neuroimaging is a well-established, valid proxy for neurological outcomes after brain injury in pediatric CNS malaria. This MRI ancillary study will add value to the Fever RCT by determining if treatment with aggressive antipyretic therapy is neuroprotective in CNS malaria. It may also help elucidate the underlying mechanism(s) of neuroprotection and expand upon FEVER RCT safety assessments., Competing Interests: Moses Chilombe has no disclosures. Karl B.

Introduction/aims: In preparation for clinical trials, it is important to better understand how disease burden changes over time in facioscapulohumeral muscular dystrophy (FSHD) and to assess the capability of select metrics to detect these changes. This study aims to evaluate FSHD disease progression over 1 year and to examine the sensitivity of several outcome measures in detecting changes during this interval., Methods: We conducted a 12-month prospective observational study of 41 participants with FSHD. Participants were evaluated at baseline, 6 months, and 12 months with serial strength testing (manual muscle testing or MMT and maximum voluntary isometric contraction testing or MVICT), functional testing (FSHD-Composite Outcome Measure or FSHD-COM, FSHD Clinical Severity Score or CSS, and FSHD Evaluation Score or FES), sleep and fatigue assessments, lean body mass measurements, respiratory testing, and the FSHD-Health Index patient-reported outcome. Changes in these outcome measures were assessed over the 12-month period. Associations between changes in outcome measures and both age and sex were also examined., Results: In a 12-month period, FSHD participant function remained largely stable with a mild worsening of strength, measured by MMT and standardized MVICT scores, and a mild loss in lean body mass., Discussion: The abilities and disease burden of adults with FSHD are largely static over a 12-month period with participants demonstrating a mild average reduction in some measures of strength. Selection of patients, outcome measures, and trial duration should be carefully considered during the design and implementation of future clinical studies involving FSHD patients., (© 2024 Wiley Periodicals LLC.)
