Are patients with gout with negative dual-energy computed tomography for monosodium urate crystal deposition easy-to-treat?

OBJECTIVES: To determine the clinical associations and predictive value of two thresholds of negative dual-energy CT (DECT) for MSU crystal deposition in gout patients initiating urate lowering therapy (ULT), and identify which threshold is more clinically relevant. METHODS: Patients from the CRYSTALILLE cohort with a diagnosis of gout naive to ULT with baseline DECT scans of knees and feet were selected. Two thresholds of positivity for DECT detection of MSU crystal deposition were considered (<0.01 cm3 and <0.1 cm3). Baseline characteristics and the prediction of key outcomes after ULT initiation including reaching serum urate (SU) levels <6.0 and 5.0 mg/dl and occurrence of flares at 6, 12 and 24 months, associated with both thresholds of negative DECTs were compared with those of. PATIENT: s having positive DECT scans. RESULTS: 211 patients aged 66.2 years [57; 75.8] with a symptom duration of 3 years [0; 7.8] were included. 38/211 (18%) and 90/211 (43%) had negative DECT scans for the 0.01 and 0.1 cm3 thresholds, respectively. Factors associated with negative DECT scans were younger age, shorter symptom duration, and absence of cardiovascular disease for both volume thresholds. 9/39 (23.1%), 3/26 (11.5%), and 1/18 (5.6%) of patients with <0.1 cm3 MSU crystals had flares at 6, 12 and 24 months, respectively, compared with 18/45 (40.0%), 9/36 (25.0%) and 2/18 (11.1%) patients with ≥0.1 cm3 (p> 0.05).Overall, 95 patients (68.3%) reached SU levels <6.0 mg/dl and 68 (48.9%) <5.0 mg/dl, without any difference between positive and negative DECTs, with ULT dosages which tended to be lower in patients with negative DECT. CONCLUSION: The 0.1 cm3 threshold was better correlated to clinical presentation and evolution than 0.01 cm3. Patients with gout with negative DECTs exhibit milder disease and a lower comorbidity burden. They do not exhibit particularly easy-to-treat hyperuricemia, but may have a lower risk of flares.

Ultrafast MRI using deep learning echoplanar imaging for a comprehensive assessment of acute ischemic stroke.

OBJECTIVES: Acute ischemic stroke (AIS) is an emergency requiring both fast and informative MR sequences. We aimed to assess the performance of an artificial intelligence-enhanced ultrafast (UF) protocol, compared to the reference protocol, in the AIS management. METHODS: We included patients admitted in the emergency department for suspected AIS. Each patient underwent a 3-T MR protocol, including reference acquisitions of T2-FLAIR, DWI, and SWI (duration: 7 min 54 s) and their accelerated multishot EPI counterparts for T2-FLAIR and T2*, complemented by a single-shot EPI DWI (duration: 1 min 54 s). Two blinded neuroradiologists reviewed each dataset, assessing DWI (detection, location, number of acute lesions), FLAIR (vascular hyperintensities, visibility of acute lesions), and SWI/T2* (hemorrhagic transformation, thrombus). We compared the agreement between the diagnoses obtained with both protocols using kappa coefficients. RESULTS: A total of 173 patients were included consecutively, of whom 80 with an AIS in DWI. We found an almost perfect agreement between the UF and reference protocols regarding the detection, distribution, number of AIS in DWI (κ = 0.98, 0.98, and 0.87 respectively), the presence of vascular hyperintensities, and the presence of a parenchymal hyperintensity in the AIS region in FLAIR (κ = 0.93 and 0.89 respectively). Agreement was substantial in T2*/SWI for thrombus detection, and fair for hemorrhagic transformation detection (κ = 0.64 and 0.38 respectively). Differential diagnoses were similarly detected by both protocols (κ = 1). CONCLUSIONS: Our AI-enhanced ultrafast MRI protocol allowed an effective detection and characterization of both AIS and differential diagnoses in less than 2 min. KEY POINTS: • The AI-enhanced ultrafast MRI protocol allowed an effective detection of acute stroke. • Characterization of stroke features with the UF protocol was equivalent to the reference sequences. • Differential diagnoses were detected similarly by the UF and reference protocols.

Early Intensive Bimanual Stimulation Program (BB-Bim) for Infants at Risk of Unilateral Cerebral Palsy: A Randomized, Multiple-Baseline, Single-Case Study.

IMPORTANCE: Clinical practice guidelines for infants at high risk of cerebral palsy (CP) emphasize the importance of very early and intensive intervention. OBJECTIVE: To determine the feasibility of a new, home-based, early intensive bimanual stimulation program (BB-Bim) and its impact on hand function in infants at risk of unilateral CP. DESIGN: Single case experimental design, multiple baseline across subjects, lasting from 12 to 15 wk, including a 4- to 7-wk randomized baseline, followed by 8 wk of BB-Bim. SETTING: Home. PARTICIPANTS: Infants (ages 3-12 mo) with suspected unilateral CP, whose parents agreed to participate in the stimulation program. INTERVENTION: Parent-provided bimanual stimulation 20 min/day, 6×/wk, with weekly occupational therapist coaching visits. MEASURES: Weekly repeated measures were the Hand Assessment in Infants (HAI) and Goal Attainment Scaling (GAS). Feasibility and relevance were assessed with a logbook and a parental report, including 10 continuous 0-10 scaled questions. RESULTS: Six infants were included (2 with left and 4 with right brain lesions). Parents provided a mean 3.4 to 6.2 stimulation sessions/wk. Feasibility and relevance were highly rated (Ms = 8.2-9.6, SDs = 0.2-1.3). Stimulation significantly improved HAI bimanual and total scores for all infants, with no impact on HAI unilateral scores. GAS scores improved with stimulation (significant for 3 infants). CONCLUSIONS AND RELEVANCE: BB-Bim was feasible and tended to improve bimanual function in infants at risk of unilateral CP. What This Article Adds: Parent-provided daily bimanual stimulation at home is feasible when parents are coached weekly by an occupational therapist. Bimanual stimulation seems to improve functional interactions between the hands among infants at high risk of unilateral CP.

Systematic Review and Meta-analysis of Histological Gastric Biopsy Aspects According to the Updated Sydney System in Children.

OBJECTIVES: A descriptive and comparative study of gastric histological aspects according to the updated Sydney classification (USC), obtained from Helicobacter pylori-positive versus H pylori-negative children referred for upper gastrointestinal endoscopy. METHODS: The Prisma method was used to perform a systematic review and meta-analysis. Selection criteria were based on following key words USC, H pylori, children, endoscopy, or biopsy. Publication biases were assessed according to the Newcastle-Ottawa Scale, and a meta-regression analysis was done. The study was registered on the PROSPERO platform. RESULTS: Between 1994 and 2017, 1238 references were found; 97 studies were retained for the systematic review with a total number of 25,867 children; 75 studies were selected for the meta-analysis concerning 5990 H pylori-infected and 17,782 uninfected children.H pylori-positive versus H pylori-negative children, according to the USC, showed significantly higher relative risk for gastric antral and corpus chronic inflammation, presence of neutrophils, and of lymphoid follicles, and gastric mucosa atrophy, whereas, intestinal metaplasia showed a significantly higher RR only in antral biopsies. The meta-regression analysis showed that H pylori-positive versus H pylori-negative children had significantly higher risk only for corpus activity according to age, recurrent abdominal pain, and geographical area of low H pylori prevalence. CONCLUSIONS: H pylori infection in children was associated with higher relative risk for gastric antral and corpus chronic inflammation, presence of neutrophils, lymphoid follicles, and rare gastric mucosa atrophy, whereas, rare intestinal metaplasia was only significantly higher in the antral area.

Do high-dose progestins impair sexual function in women treated for endometriosis? A prospective observational longitudinal study.

INTRODUCTION: High-dose progestins are used as an effective therapy for painful symptoms of endometriosis but their impact on sexual function has been poorly studied. The study aims to assess the impact of high-dose progestin on sexual function among women treated for endometriosis. MATERIAL AND METHODS: In this bicenter prospective observational study, women with endometriosis who received medical or surgical treatment for endometriosis and who were sexually active were included. They completed the Sexual Activity Questionnaire (SAQ, a validated tool) before (T0) and 12 months after (T1) endometriosis treatment. We classified patients into two groups according to whether they were using high-dose progestins at T1: a high-dose progestin group and a control group. The main outcome was sexual function measured by the SAQ score (from 0 to 30) at T1. The secondary outcomes were each individual SAQ item, the dyspareunia 100-mm visual analog scale (VAS) and the quality of life assessed with EuroQoL Group 5D Index (EQ-5D) at T1. We also assessed the change in dyspareunia VAS and quality of life between T0 and T1. The Ethics Committee of Ile-de-France (Act 2004-806, 9 August 2004) approved the study. RESULTS: Among 214 women included, 25 (12%) were exposed to high-dose progestins at T1. The SAQ score of women exposed to high-dose progestins was significantly lower compared with the control group, with or without adjustment for covariates (15.5 ± 6.3 vs 18.3 ± 6.2, P = .03, adjusted effect size -0.44 [95% CI -0.86 to -0.02], P = .04). High-dose progestin intake at T1 was associated with a lower subscore on two SAQ items: pleasure (1.8 ± 0.8 vs 2.2 ± 0.9, P = .02), and satisfaction with frequency of intercourse (1.2 ± 1.2 vs 1.8 ± 1.1, P = .02). In the overall population, dyspareunia VAS and quality of life assessed by EQ-5D improved between T0 and T1 (45 ± 29 at T0 vs 28 ± 29 at T1, P < .001; 0.78 ± 0.14 at T0 vs 0.86 ± 0.14 at T1, P < .001, respectively). At T1, the groups did not differ significantly for dyspareunia VAS (effect size 0.36 [95% CI -0.06 to 0.78], P = .10) and quality of life (EQ-5D, effect size 0.02 [95% CI -0.40 to 0.44], P = .91). CONCLUSION: In this observational study, high-dose progestins impair the sexual function of women treated for endometriosis even though they improved dyspareunia.

Hypothalamic Structural and Functional Imbalances in Anorexia Nervosa.

The hypothalamus contains integrative systems that support life, including physiological processes such as food intake, energy expenditure, and reproduction. Here, we show that anorexia nervosa (AN) patients, contrary to normal weight and constitutionally lean individuals, respond with a paradoxical reduction in hypothalamic levels of glutamate/glutamine (Glx) upon feeding. This reversal of the Glx response is associated with decreased wiring in the arcuate nucleus and increased connectivity in the lateral hypothalamic area, which are involved in the regulation on a variety of physiological and behavioral functions including the control of food intake and energy balance. The identification of distinct hypothalamic neurochemical dysfunctions and associated structural variations in AN paves the way for the development of new diagnostic and treatment strategies in conditions associated with abnormal body mass index and a maladaptive response to negative energy balance.

Usefulness of a Visual Analog Scale for Measuring Anxiety in Hospitalized Patients Experiencing Pain: A Multicenter Cross-Sectional Study.

BACKGROUND: Anxiety is common in hospitalized patients and can worsen pain or lead to unsuccessful pain relief. AIMS: The purpose of this study was to evaluate the usefulness of measuring anxiety with a visual analog scale (VAS) in the hospitalized patient experiencing pain. DESIGN: We conducted a multiple-center cross-sectional study. PARTICIPANTS/SUBJECTS: Adult inpatients experiencing moderate to severe pain defined by a pain VAS score ≥40 of 100 were included. METHODS: Pain and anxiety data were collected using the following instruments: pain VAS, anxiety VAS, State Anxiety Scale of the Spielberger State-Trait Anxiety Inventory (STAI-YA) and Anxiety Subscale of the Hospital Anxiety and Depression Scale (HAD-A). RESULTS: Data were collected from 394 patients. Of those patients, 43.6% (171 of 392) and 36.6% (143 of 391) had significant anxiety according to STAI-Ya and HAD-A, respectively. Correlation was good between anxiety-VAS and STAI-YA (ρ = 0.67 [95% confidence interval 0.61-0.72]) and moderate between anxiety VAS and HAD-D (ρ = 0.48 [0.39-0.56]). The main factor predictive of situational anxiety was history of anxiety-depression symptoms (odds ratio = 2.95 [1.93-4.56]). For anxiety VAS score ≥ 40 of 100, the sensitivity for detecting anxiety was 81% with 70% specificity. CONCLUSION: This study confirmed the high prevalence of anxiety among inpatients experiencing pain, demonstrated the capacity of a VAS to assess this anxiety, determined an anxiety VAS cutoff level to screen for significant anxiety, and identified risk factors of anxiety in this population. Anxiety VAS has been found to be an easy-to-use method familiar to caregivers, with all the advantages needed for an effective screening instrument. An anxiety VAS score ≥40 of 100 would thus warrant particular attention to adapt care to the patient's anxiety-related pain and initiate specific therapeutic interventions.

Pain coping strategies in children with cerebral palsy.

AIM: To describe coping strategies in children and adolescents with cerebral palsy (CP), relative to age. METHOD: Patients were prospectively recruited from two paediatric rehabilitation centres in France. The Pediatric Pain Coping Inventory - French and Structured Pain Questionnaire were completed by an experienced professional for each child. RESULTS: One hundred and forty-two children with CP were included (80 males, 62 females; median age 12y; IQR=8-15y). They generally used fewer coping strategies than typically developing children ('Seeks social support and action': 12.47 vs 12.85, p=0.477; 'Cognitive self-instruction': 9.28 vs 10.90, p<0.001; 'Distraction': 4.89 vs 7.00, p<0.001; 'Problem solving': 4.43 vs 5.19, p<0.001). In the CP group, 'Seeks social support and action' decreased with age (p=0.021) and 'Cognitive self-instruction' increased with age (p<0.001). 'Problem solving' and 'Distraction' did not change with age. Coping strategies were influenced by Gross Motor Function Classification System level (p=0.022) and history of surgery (p=0.002). INTERPRETATION: Children with CP generally used fewer coping strategies than typically developing children and tended to rely on social support. Use of active strategies increased with age; however, they appeared later than in typically developing children and were used to a lesser extent. WHAT THIS PAPER ADDS: Children with cerebral palsy (CP) use fewer pain-coping strategies than typically developing children. Children with CP tend to use social support to cope with pain. Children with CP learn more appropriate strategies from previous painful experiences. Active coping strategies appear later but remain underused in children with CP.

ESTRATEGIAS DE AFRONTAMIENTO DEL DOLOR EN NIÑOS CON PARÁLISIS CEREBRAL: OBJETIVO: Describir estrategias de afrontamiento en niños y adolescentes con parálisis cerebral (PC), en relación con la edad. MÉTODO: Los pacientes fueron reclutados prospectivamente de dos centros de rehabilitación pediátrica en Francia. El Inventario de Afrontamiento del Dolor Pediátrico - Cuestionario de Dolor Francés y Estructurado fue completado por un profesional con experiencia para cada niño. RESULTADOS: Se incluyeron 142 niños con PC (80 varones, 62 mujeres; mediana de edad de 12 años; IQR = 8-15 años). En general, los niños con PC utilizaron menos estrategias de afrontamiento que los niños con desarrollo típico ("Busca apoyo social y acción": 12,47 vs 12,85, p = 0,477; "Autoinstrucción cognitiva": 9,28 vs 10,90, p <0,001; "Distracción": 4,89 vs 7,00, p <0,001; "Resolución de problemas": 4,43 vs 5,19, p <0,001). En el grupo de PC, la búsqueda de apoyo y acción social disminuyó con la edad (p = 0,021) y la autoinstrucción cognitiva aumentó con la edad (p <0,001). La "resolución de problemas" y la "distracción" no cambiaron con la edad. Las estrategias de afrontamiento se vieron influenciadas por el nivel del Sistema de Clasificación de la Función Motora Gruesa (p = 0,022) y los antecedentes quirúrgicos (p = 0,002). INTERPRETACIÓN: Los niños con PC generalmente usaron menos estrategias de afrontamiento que los niños con un desarrollo típico y tendían a confiar en el apoyo social. El uso de estrategias activas aumenta con la edad; sin embargo, aparecieron más tarde que en los niños con un desarrollo típico y se utilizaron en menor medida.

ESTRATÉGIAS PARA LIDAR COM A DOR EM CRIANÇAS COM PARALISIA CEREBRAL: OBJETIVO: Descrever estratégias para lidar com a dor em crianças e adolescentes com paralisia cerebral (PC), com relação à sua idade. MÉTODO: Pacientes foram prospectivamente recrutados em dois centros de reabilitação pediátrica na França. O Inventário Pediátrico de Manejo da Dor - Francês e o Questionário Estruturado sobre dor foram completados para cada criança por um profissional com experiência. RESULTADOS: Cento e quarenta e duas crianças com PC foram incluídas (80 do sexo masculino, 62 do sexo feminino; idade mediana 12a; IIQ=8-15a). Elas geralmente usaram menos estratégias para lidar com a dor do que crianças com desenvolvimento típico ('Procura suporte e ação social': 12,47 vs 12,85, p=0=,477; 'Auto-instrução cognitiva': 9,28 vs 10,90, p<0,001; 'Distração: 4,89 vs 7,00, p<0,001; 'Resolução do problema': 4,43 vs 5,19, p<0,001). No grupo com PC, 'Procura suporte e ação social' diminuiu com a idade (p=0,021) e Auto-instrução cognitiva' aumentou com a idade (p<0,001). 'Resolução de problemas' e 'Distração' não mudaram com a idade. As estratégias de manejo da dor foram influenciadas pelo nível do Sistema de Classificação da Função Motora Grossa (p=0,022) e histórico de cirurgia (p=0,002). INTERPRETAÇÃO: Crianças com PC geralmente usam menos estratégias para lidar com a dor do que crianças com desenvolvimento típico, e tendem a depender de suporte social. O uso de estratégias efetivas aumentou com a idade; no entanto, elas aparecem mais tarde do que em crianças com desenvolvimento típico, e são utilizadas em menor escala.

New sagittal classification of AIS: validation by 3D characterization.

INTRODUCTION AND AIM: In order to improve surgical planning of sagittal correction in AIS, we proposed a new sagittal classification-Abelin-Genevois et al. Eur Spine J (27(9):2192-2202, 2018. https://doi.org/10.1007/s00586-018-5613-1 ). The main criticism is related to the fact that 2D lateral view results from the projection of the 3D deformity. The aim of this study is to show that the new sagittal classification system is a reliable system to describe the different sagittal scenarios that AIS could create both in 2D and 3D. METHODS: We performed retrospective radiograph analysis of prospectively collected data from 93 consecutive AIS patients who underwent an examination of the whole spine using the EOS® imaging system. 2D (Keops®) and 3D analyses (sterEOS®) provided frontal and sagittal spinal and spinopelvic parameters. In addition, 3D analysis provided apical vertebra rotation (AVR). RESULTS: Comparing 2D and 3D measurements for the general cohort, excellent correlation can be found for all parameters, but only fairly good for T10L2 and L1S1 angles. The highest variability was observed for T10L2, differences between 2D and 3D measurements being greater when the Cobb angle increased. AVR did not influence concordance between 2D and 3D measurements. Eighty-two percent were similarly classified in 2D and 3D according to the new classification. Misclassified patients were all AIS sagittal type 3 in 3D analysis, thoracolumbar junction (TLJ) lordosis being underestimated on 2D view. DISCUSSION: In conclusion, for the majority of cases (82%), 2D analysis may provide enough information for decision making when using a semi-automated 2D measurement system. However, in severe cases, especially when Cobb angle exceeds 55°, 3D analysis should be used to get a more accurate view on the thoracolumbar junction behavior.

Phenotypical characterization of peanut allergic children with differences in cross-allergy to tree nuts and other legumes.

BACKGROUND: Peanut allergy in children is often associated with allergies to tree nuts and/or legumes. The aim of this study was to analyze in cluster a cohort of children allergic to peanuts and assessed for cross-reactivity to nuts and legumes and to identify different phenotypes. METHODS: We included retrospectively 317 children with peanut allergy evaluated at the Allergy Unit of the Saint Vincent Hospital of Lille in the last 12 years. A complete workup for peanut allergy and nuts and legumes was carried out for each patient. A hierarchical agglomerative clustering method was used to search for clusters of individuals in the evaluated cohort. RESULTS: Cross-allergy to TN and/or other legumes was identified in 137 patients (43.2%), atopic dermatitis being a major risk factor (adjusted OR = 16 [95% CI: 7.4-37]; p < 0.001). Three phenotypes emerged from cluster analysis. Cluster 1 (72 patients) is characterized by high level of rAra h 2, low threshold reactive doses for peanut and high proportion of asthma; Cluster 2 (93 patients) is characterized by high threshold reactive doses for peanut and the lowest proportion of cross-allergy to TN and/or legumes; Cluster 3 (152 patients) has a high risk of cross-allergy to TN and/or legumes and most patients suffer from eczema. CONCLUSIONS: The three phenotypes highlighted by this study could be useful to identify children with high risk of cross-allergic reaction to TNs and legumes early after PA diagnosis.

Identification of a Circulating MicroRNA Profile as a Biomarker of Metastatic Cutaneous Melanoma.

No specific biomarkers for prognostication or evaluation of tumour load in melanoma have been reported to our knowledge. MicroRNAs (miRNAs) are strongly implicated in oncogenesis and tumour progression, and their circulating forms have been studied as potential biomarkers in oncology. The aim of this prospective study was to identify a melanoma-specific profile of plasma miRNAs. A screening phase, using RNA microarray, was conducted on plasma from 14 patients with metastatic melanoma and 5 healthy subjects. Selected miRNAs were analysed by RTqPCR in 2 independent training and validation cohorts including, respectively, 29 and 31 patients and 16 and 43 control subjects. A profile of 2 miRNAs (miR-1246 and miR-185) significantly associated with metastatic melanoma with a sensitivity of 90.5% and a specificity of 89.1% was identified. This plasma miRNA profile may become an accurate non-invasive biomarker for melanoma.

Prevalence of Intestinal Parasitosis in Guinea: Systematic Review of the Literature and Meta-Analysis.

BACKGROUND: Intestinal parasitosis constitute a major public health issue, particularly in sub-tropical and tropical areas. Even though they are classified as neglected tropical diseases, no national study has been carried out recently in Guinea to estimate the prevalence of intestinal parasitosis. OBJECTIVE: A systematic review and meta-analysis aimed to determine the overall prevalence of intestinal parasitosis in Guinea. METHOD: The PRISMA method was used to perform a systematic review and meta-analysis. The studies carried out in order to study intestinal parasitosis in Guinea and published between 2010 and 2020 were searched in online public databases. The prevalence of parasitosis was calculated by a random-effects meta-analysis. Subgroup comparisons were performed using Q-tests. Statistical analyses were performed with the R software. This review was registered with PROSPERO under the identification number CRD42022349743. RESULTS: 69 studies were selected out of 1230 studies identified in online public databases. The meta-analysis involved 44,186 people with an overall prevalence of intestinal parasitic infections of 52%. CONCLUSIONS: This is the first study in Guinea to assess the prevalence of intestinal parasitic infections in different regions of the country. It was found that intestinal parasitosis are a real health problem in Guinea, hence, the need to put in place national strategies for regular control.

Yoga in the Rehabilitation of Post-Stroke Sequelae: A Non-Inferiority Randomized Controlled Trial.

Introduction: Stroke survivors can experience various consequences that affect their physical and psychological balance. Yoga seems to be relevant for this population as it allows to work on both the body and the mind. The first objective of this study was to investigate the non-inferiority of yoga compared with conventional physical activity in improving physical function in patients with chronic post-stroke sequelae. The secondary objective was to investigate the superiority of yoga in improving the mental health of these patients. Methods: A randomized controlled trial was conducted. Thirty-six patients were randomized into two groups to practice a yoga program (YOG'AVC) or the Fitness and Mobility Exercise (FAME) program. Patients were assessed in a blinding mode pre- (T0) and post-program (T1) and 3-4 months after completion (T2). The physical assessments were the Berg Balance Scale, timed up and go test, 6-minute walk test, and quadriceps strength measured by hand-held dynamometer. Questionnaire assessments were: Activities-specific Balance Confidence Scale-Simplified, State-Trait Anxiety Inventory, Beck's Depression Inventory, and the Reintegration to Normal Living Index. Results: The YOG'AVC program was not inferior to the FAME program in improving balance, functional mobility and muscle strength. Both groups showed significant improvement (p < 0.05) between T0 and T1 in their anxiety, depression, and reintegration to normal life scores, with no significant difference between groups. Discussion: Both programs seem to be valuable in improving the physical abilities and psychological well-being of chronic post-stroke patients. However, further studies are required to confirm the difference between these programs.

Does accelerometry reflect hand function in infants at risk of unilateral cerebral palsy? A secondary analysis of BB-Bim results.

BACKGROUND: Infants at high-risk of unilateral Cerebral Palsy (UCP) may have asymmetry in upper extremity movement and function, which should be identified as soon as possible for management. AIMS: To explore the feasibility of using two AX3 Axivity monitors in wrist-worn bracelets to quantify movements, and to identify whether accelerometry parameters are consistent with hand function. METHODS AND PROCEDURES: 6 infants at high risk of UCP (aged 3 to -12 months) were included in a Single-Case Experimental Design to explore the impact of an 8-week bimanual stimulation home program. OUTCOMES: Each week of the baseline (randomized duration 4-7 weeks) and 8-week program, the Hand Assessment for Infants (HAI) was performed and accelerometry parameters were collected during HAI and also during spontaneous activity, several times a week. RESULTS: Actimetry was analyzed during HAI and 238 spontaneous activity sessions (mean 42 ± 21 min). Actimetry ratios distribution and evolution show a high variability, especially for spontaneous activity. No strong correlation was found between HAI scores and accelerometry parameters, either collected during HAI, or during spontaneous activity times. CONCLUSION AND IMPLICATIONS: Despite its feasibility, using accelerometry bracelets looks unreliable for detecting and monitoring hand function in infants under one year.

Factors influencing the kinetics of MSU crystal depletion measured with dual-energy CT in patients with gout.

OBJECTIVE: To examine factors influencing the kinetics of monosodium urate (MSU) crystal dissolution measured with dual-energy computed tomography (DECT) during follow-up of patients with gout. METHODS: Patients with a diagnosis of gout with baseline knees and feet DECT scans exhibiting MSU crystal volumes ≥0.1 cm3 and at least one follow-up DECT were included. Spearman's correlation coefficient was used to search for association between change from baseline MSU crystal volume at 6, 12, 18 and 24 months and serum urate (SU) level. Associations between percentage change from the baseline volume of MSU crystal deposits and explanatory variables were assessed using linear mixed models. RESULTS: Sixty-two patients (age 67.3±12.8 years; 53 (85%) males) cumulating 104 follow-up DECT scans were included. Overall, SU target levels (<6.0 and <5.0 mg/dL) were achieved by 48 (77%) and 36 (58%) patients, respectively. There was a good correlation (r=0.66; p<0.0001) observed between SU level and percentage change in MSU crystal volume. The median decrease from baseline MSU crystal volume was greater in patients reaching the <5.0 mg/dL SU target than in those reaching ≥5.0 SU <6.0 mg/dL: -85% (95% CI: -94% to -72%) versus -40% (-57% to -22%; p<0.05) at 12 months. In multivariable analysis, time (in days) with a multilevel coefficient of -0.06 (95% CI: -0.08 to -0.03, p<0.001), hypertension (coefficient: 41.87, 95% CI: 16.38 to 67.18, p<0.01) and SU level <5.0 mg/dL (coefficient: -39.46, 95% CI: -70.93 to -8.34, p=0.02) were the only variables significantly associated with MSU crystal volume change. CONCLUSION: In patients with DECT-measured MSU crystal deposition, reaching the <5.0 mg/dL SU target provides more extensive and rapid crystal dissolution than reaching the <6.0 mg/dL SU target.

Two-Year Outcome of Aflibercept Intravitreal Injection in Vitrectomized Eyes with Diabetic Macular Edema.

Purpose: To evaluate the efficacy of intravitreal aflibercept injection (IAI) for vitrectomized eyes with diabetic macular edema (DME) at two years. Methods: This is a prospective, non-comparative, multicenter observational study including diabetic patients with visual acuity between 20/400 to 20/40 due to DME, who have undergone vitrectomy at least 3 months before the first aflibercept injection. Treatment protocol included 5 monthly aflibercept injection followed by a ProReNata regimen during the first year. Participants were managed at clinicians' discretion using Treat and Extend or Observe and Plan regimen during the second year. Visual acuity, OCT findings and number of IAI were assessed at two years. Results: Available data for 28 eyes with DME previously vitrectomized treated with aflibercept intravitreal injection during at least 2 years were collected. Visual gain was +5.4 letters (p = 0.01), and central macular thickness decreased significantly -62µm, p < 0.001) at 2 years. Resolution of macular edema allowing discontinuation of aflibercept was observed in 7 eyes (15%). Mean number of injections was 14.6, and mean interval injection was 6.4 weeks for 2 years. Conclusion: These results suggest that IAI is beneficial in vitrectomized eyes leading to improvement of visual and anatomical outcome which was maintained for 2 years.

Transposition and Normalization of the Mini-Mental State Examination in French Sign Language.

OBJECTIVE: Due to the lack of a validated translation, the mini-mental state examination (MMSE) cannot be used to screen for suspected dementia in deaf people who communicate in French Sign Language (FSL). Taking into consideration the cultural and linguistic features of this specific population, we transposed the validated French version of the MMSE into a version adapted to FSL users: mini-mental state-langue des signes (MMS-LS). The objective of our work was to obtain screening norms for the MMS-LS. METHODS: The MMS-LS was tested on 194 deaf users of FSL with clinical dementia rating as the gold standard. Healthy and demented participants were seen for two or three consecutive testing sessions at 1-year intervals. RESULTS: The MMS-LS exhibited excellent internal coherence validity (Cronbach's α = .81), unidimensionality (p = .002), and excellent sensitivity (p < .001). The MMS-LS score declined with overt and severe dementia. CONCLUSION: The percentiles obtained are useful norms for clinical assessment but must be interpreted with precaution due to the small number of participants (related to recruitment constraints) in the present study. In order to facilitate clinical use, the MMS-LS has been made available online, together with an instructions manual and clinical advice useful for improved awareness of the specific nature of this population.

Direct Oral Anticoagulants and Non-valvular Atrial Fibrillation: Compliance with Dose Level Guidelines in Patients Aged 80 Years and Over.

BACKGROUND: Direct oral anticoagulants (DOACs) are currently recommended as first-line or (after vitamin K antagonists) second-line therapy for preventing stroke and systemic embolism in patients with non-valvular atrial fibrillation. In patients aged 80 years and over, however, the fear of DOAC-associated bleeding and the complexity of DOAC dosing regimes may prompt physicians to prescribe inappropriate dose levels. OBJECTIVE: The objective of this study was to determine compliance with French and European guidelines of doses of three DOACs (apixaban, dabigatran and rivaroxaban) prescribed to patients aged over 80 years in an indication of non-valvular atrial fibrillation, and to identify factors associated with poor compliance. METHODS: We performed a retrospective single-centre study of patients aged over 80 years routinely treated with a DOAC (apixaban, dabigatran or rivaroxaban) for non-valvular atrial fibrillation at Valenciennes General Hospital (Valenciennes, France) between 1 January, 2016 and 31 December, 2017. We determined compliance with French and European guidelines of DOAC doses as a function of each patient's clinical and laboratory parameters, and thus classified the regime as being appropriately dosed, overdosed or underdosed. RESULTS: A total of 703 patients (371 taking apixaban, 92 taking dabigatran and 240 taking rivaroxaban) were included in the study. We found that 274 patients (39%) had been prescribed an inappropriate DOAC regime, with underdosing in 241 cases (34%) and overdosing in 33 cases (5%). Underdosing mainly concerned the two most widely prescribed DOACs, i.e. apixaban (39% of all apixaban prescriptions were underdosed) and rivaroxaban (40%). Concomitant treatment with an antidepressant was associated with underdosing of rivaroxaban or apixaban (p = 0.0339). In contrast, initial management in a neurology department was associated with appropriate dosing (p = 0.000146) for both these DOACs. CONCLUSIONS: Among patients with non-valvular atrial fibrillation aged 80 years and over, about 40% of DOAC prescriptions feature inappropriate dose levels. It might be possible to reduce inappropriate dosing by raising awareness among hospital-based and private-practice prescribers, providing prescription support tools for DOACs, and performing medication reconciliations and reviews at hospital and in private practice.

One-Year Outcome of Aflibercept Intravitreal Injection in Vitrectomized Eyes with Diabetic Macular Edema.

AIM: To evaluate the efficacy of intravitreal Aflibercept injection (IAI) for vitrectomized eyes with diabetic macular edema (DME) at one year. METHODS: This is a prospective, non-comparative, multicenter observational study including diabetic patients whose HbA1c is < 9%, with visual acuity between 20/400 to 20/40 due to DME, who have undergone vitrectomy since at least 3 months before the first aflibercept injection. Treatment protocol included 5 monthly aflibercept injection followed by a ProReNata regimen during the first year. Visual acuity, OCT findings and number of IAI were assessed at 6 months and one year. RESULTS: Forty-six eyes were included. Indications for vitrectomy were epiretinal membrane (58.7%), intravitreal hemorrhage (26.1%), and vitreomacular traction (8.7%), retinal detachment (4.3%), and other cause (4.3%). Median duration of macular edema was 3 years. Median interval between vitrectomy and first visit was 9 months. Thirty eyes were non-naïve and received previously thermal laser (44.3%), intravitreal injection of triamcinolone (26.7%), of ranibizumab (70%), of dexamethasone implant (36.7%), or bevacizumab (6.7%). Data was available for 35 eyes at 1 year. Visual gain was significant, +6 letters (p <0.001) and central subfield thickness (CST) decreased significantly (-108µm, p < 0.001) at 1 year. Mean number of injections was 9.3 and mean interval injection was 5.8 weeks. CONCLUSION: These results suggest that IAI may be beneficial in vitrectomized eyes with refractory DME which require frequent injections to obtain visual and anatomical improvement.

mHealth App for Pressure Ulcer Wound Assessment in Patients With Spinal Cord Injury: Clinical Validation Study.

BACKGROUND: Clinical evaluation of a pressure ulcer is based on quantitative and qualitative evaluation. In clinical practice, acetate tracing is the standard technique used to measure wound surface area; however, it is difficult to use in daily practice (because of material availability, data storage issues, and time needed to calculate the surface area). Planimetry techniques developed with mobile health (mHealth) apps can be used to overcome these difficulties. OBJECTIVE: The goal of this study was to evaluate the metrological properties of a free-access mHealth app, called imitoMeasure, to assess pressure ulcers. METHODS: This was a noninterventional, validation study. We included patients with spinal cord injury presenting with a pressure ulcer, regardless of its stage or location. We performed wound measurements with a ruler, and we performed acetate tracing using a transparent dressing with a wound measurement grid. Wound evaluation via the mHealth app was conducted twice by the main investigator and also by a coinvestigator to determine validity, intrarater reproducibility, and interrater reproducibility. Bland-Altman plots and intraclass correlation coefficients were used to compute the minimal detectable change percentage. RESULTS: Overall, 61 different pressure ulcers were included. The validity, intrarater reproducibility, and interrater reproducibility of the mHealth app vs acetate tracing (considered the method of reference) were good, with intraclass correlation coefficients of 0.97 (95% CI 0.93-0.99), 0.99 (95% CI 0.98-0.99), and 0.98 (95% CI 0.96-0.99), respectively, and minimal detectable change percentages between 17% and 35%. CONCLUSIONS: The imitoMeasure app had good validity and reproducibility. It could be an alternative to standard wound assessment methods. Further studies on larger and more diverse wounds are needed.
