Targeting HER2/HER3 co-mutations in metastatic breast cancer: Case reports of exceptional responders to trastuzumab and pertuzumab therapy.

BACKGROUND: Overexpression of HER2 plays an important role in cancer progression and is the target of multiple therapies in HER2-positive breast cancer. Recent studies have also highlighted the presence of activating mutations in HER2, and HER3 that are predicted to enhance HER2 downstream pathway activation in a HER2-dependent manner. METHODS: In this report, we present two exceptional responses in hormone receptor-positive, HER2-nonamplified, HER2/HER3 co-mutated metastatic breast cancer patients who were treated with the anti-HER2-directed monoclonal antibodies, trastuzumab and pertuzumab. RESULTS: Both patients acheived exceptional responses to treatment, suggesting that combined trastuzumab, pertuzumab, and endocrine therapy could be a highly effective therapy for these patients and our observations could help prioritize trastuzumab deruxtecan as an early therapeutic choice for patients whose cancers have activating mutations in HER2.

Impact of CFTR Modulation on Pseudomonas aeruginosa Infection in People With Cystic Fibrosis.

BACKGROUND: Pseudomonas aeruginosa is a multidrug-resistant pathogen causing recalcitrant pulmonary infections in people with cystic fibrosis (pwCF). Cystic fibrosis transmembrane conductance regulator (CFTR) modulators have been developed that partially correct the defective chloride channel driving disease. Despite the many clinical benefits, studies in adults have demonstrated that while P. aeruginosa sputum load decreases, chronic infection persists. Here, we investigate how P. aeruginosa in pwCF may change in the altered lung environment after CFTR modulation. METHODS: P. aeruginosa strains (n = 105) were isolated from the sputum of 11 chronically colonized pwCF at baseline and up to 21 months posttreatment with elexacaftor-tezacaftor-ivacaftor or tezacaftor-ivacaftor. Phenotypic characterization and comparative genomics were performed. RESULTS: Clonal lineages of P. aeruginosa persisted after therapy, with no evidence of displacement by alternative strains. We identified commonly mutated genes among patient isolates that may be positively selected for in the CFTR-modulated lung. However, classic chronic P. aeruginosa phenotypes such as mucoid morphology were sustained, and isolates remained just as resistant to clinically relevant antibiotics. CONCLUSIONS: Despite the clinical benefits of CFTR modulators, clonal lineages of P. aeruginosa persist that may prove just as difficult to manage in the future, especially in pwCF with advanced lung disease.

Age of onset of obsessive-compulsive disorder differentially affects white matter microstructure.

Previous diffusion MRI studies have reported mixed findings on white matter microstructure alterations in obsessive-compulsive disorder (OCD), likely due to variation in demographic and clinical characteristics, scanning methods, and underpowered samples. The OCD global study was created across five international sites to overcome these challenges by harmonizing data collection to identify consistent brain signatures of OCD that are reproducible and generalizable. Single-shell diffusion measures (e.g., fractional anisotropy), multi-shell Neurite Orientation Dispersion and Density Imaging (NODDI) and fixel-based measures, were extracted from skeletonized white matter tracts in 260 medication-free adults with OCD and 252 healthy controls. We additionally performed structural connectome analysis. We compared cases with controls and cases with early (<18) versus late (18+) OCD onset using mixed-model and Bayesian multilevel analysis. Compared with healthy controls, adult OCD individuals showed higher fiber density in the sagittal stratum (B[SE] = 0.10[0.05], P = 0.04) and credible evidence for higher fiber density in several other tracts. When comparing early (n = 145) and late-onset (n = 114) cases, converging evidence showed lower integrity of the posterior thalamic radiation -particularly radial diffusivity (B[SE] = 0.28[0.12], P = 0.03)-and lower global efficiency of the structural connectome (B[SE] = 15.3[6.6], P = 0.03) in late-onset cases. Post-hoc analyses indicated divergent direction of effects of the two OCD groups compared to healthy controls. Age of OCD onset differentially affects the integrity of thalamo-parietal/occipital tracts and the efficiency of the structural brain network. These results lend further support for the role of the thalamus and its afferent fibers and visual attentional processes in the pathophysiology of OCD.

Experimental assessment of laser scarecrows for reducing avian damage to sweet corn.

BACKGROUND: Birds damage crops, costing millions of dollars annually, and growers utilize a variety of lethal and nonlethal deterrents in an attempt to reduce crop damage by birds. We experimentally tested laser scarecrows for their effectiveness at reducing sweet corn (Zea mays) damage. We presented 18 captive flocks of free-flying European starlings (Sturnus vulgaris) with fresh sweet corn ears distributed on two plots where laser and control treatments were alternated each day and allowed each flock to forage over 5 days. In 16 trials, fresh sweet corn ears were mounted on wooden sticks distributed from 0 to 32 m from laser units (Stick Trials), and in two trials birds foraged on ripe corn grown from seed in the flight pen (Natural Trials). We aimed to determine if laser-treated plots had significantly less damage overall and closer to the laser unit, and whether birds became more or less likely to forage in laser-treated plots over time. RESULTS: Lasers reduced damage overall, marginally in Stick Trials and dramatically in Natural Trials. Damage increased during each week in both trial types. Damage increased significantly with distance from lasers, and significant treatment effects occurred up to ~20 m from lasers. CONCLUSION: Our results concur with recent field trials demonstrating strong reductions in sweet corn damage when lasers are deployed. This study provides a first look at how birds respond to repeated laser exposure and whether damage increases with distance from lasers. Key differences between pen and field trials are discussed. © 2023 Society of Chemical Industry.

A novel two-catheter method for urethral catheterization improves success rates of urethral catheterization in female dogs and cats weighing less than ten kilograms.

OBJECTIVE: To compare the success rates for urethral catheterization in clinical patients using the traditional and 2-catheter techniques when placed by personnel of all experience levels. ANIMALS: 38 female cats and dogs weighing less than 10 kg were prospectively enrolled. METHODS: Enrolled animals were randomized to have a urethral catheter placed by the traditional technique or the 2-catheter method under sedation or general anesthesia. Any qualified hospital personnel of any experience level were allowed to place the catheter. If after 5 minutes the animal was not successfully catheterized, the alternate method was performed. The previous experience of the catheter placer, animal signalment, animal condition that necessitated catheter placement, time to successful placement, and which technique was successful was recorded. RESULTS: The 2-catheter technique was more successful than the traditional method (60.5% and 34.2%, respectively) for urethral catheterization when used by a variety of hospital personnel. The 2-catheter technique was successful in 63.3% of dogs and 66.6% of cats, while the traditional method was successful in 36.6% of dogs and 33.3% of cats. Eight of 9 (88.9%) novice catheter placers that placed their first urinary catheter in this study succeeded with the 2-catheter technique and only 1 was successful with the traditional method. CLINICAL RELEVANCE: The 2-catheter technique has a higher rate of success for placement of female urinary catheters in small patients that are unable to have concurrent digital palpation. This technique may also be helpful in the inexperienced catheter placer population to aid in guidance into the urethral papilla.

Pilot clinical trial and phenotypic analysis in chemotherapy-pretreated, metastatic triple-negative breast cancer patients treated with oral TAK-228 and TAK-117 (PIKTOR) to increase DNA damage repair deficiency followed by cisplatin and nab paclitaxel.

BACKGROUND: A subset of triple-negative breast cancers (TNBCs) have homologous recombination deficiency with upregulation of compensatory DNA repair pathways. PIKTOR, a combination of TAK-228 (TORC1/2 inhibitor) and TAK-117 (PI3Kα inhibitor), is hypothesized to increase genomic instability and increase DNA damage repair (DDR) deficiency, leading to increased sensitivity to DNA-damaging chemotherapy and to immune checkpoint blockade inhibitors. METHODS: 10 metastatic TNBC patients received 4 mg TAK-228 and 200 mg TAK-117 (PIKTOR) orally each day for 3 days followed by 4 days off, weekly, until disease progression (PD), followed by intravenous cisplatin 75 mg/m2 plus nab paclitaxel 220 mg/m2 every 3 weeks for up to 6 cycles. Patients received subsequent treatment with pembrolizumab and/or chemotherapy. Primary endpoints were objective response rate with cisplatin/nab paclitaxel and safety. Biopsies of a metastatic lesion were collected prior to and at PD on PIKTOR. Whole exome and RNA-sequencing and reverse phase protein arrays (RPPA) were used to phenotype tumors pre- and post-PIKTOR for alterations in DDR, proliferation, and immune response. RESULTS: With cisplatin/nab paclitaxel (cis/nab pac) therapy post PIKTOR, 3 patients had clinical benefit (1 partial response (PR) and 2 stable disease (SD) ≥ 6 months) and continued to have durable benefit in progression-free survival with pembrolizumab post-cis/nab pac for 1.2, 2, and 3.6 years. Their post-PIKTOR metastatic tissue displayed decreased mismatch repair (MMR), increased tumor mutation burden, and significantly lower levels of 53BP1, DAG Lipase ß, GCN2, AKT Ser473, and PKCzeta Thr410/403 compared to pre-PIKTOR tumor tissue. CONCLUSIONS: Priming patients' chemotherapy-pretreated metastatic TNBC with PIKTOR led to very prolonged response/disease control with subsequent cis/nab pac, followed by pembrolizumab, in 3 of 10 treated patients. Our multi-omics approach revealed a higher number of genomic alterations, reductions in MMR, and alterations in immune and stress response pathways post-PIKTOR in patients who had durable responses. TRIAL REGISTRATION: This clinical trial was registered on June 21, 2017, at ClinicalTrials.gov using identifier NCT03193853.

Evaluation of roost culling as a management strategy for reducing invasive rose-ringed parakeet (Psittacula krameri) populations.

Rose-ringed parakeets (Psittacula krameri) are one of the most widespread invasive avian species worldwide. This species was introduced to the island of Kaua'i, Hawai'i, USA, in the 1960s. The rapidly increasing population has caused substantial economic losses in the agricultural and tourism industries. We evaluated the efficacy of a roost culling program conducted by an independent contractor from March 2020 to March 2021. We estimated island-wide minimum abundance was 10,512 parakeets in January 2020 and 7,372 in April 2021. Over 30 nights of culling at four roost sites, approximately 6,030 parakeets were removed via air rifles with 4,415 (73%) confirmed via carcasses retrieval. An estimated average of 45 parakeets were removed per hour of shooter effort. The proportion of adult females removed in 2020 was 1.9 × greater when culled outside of the estimated nesting season. Of the four roosts where culling occurred, the parakeets fully abandoned three and partially abandoned one site. Of the three fully abandoned roosts, an estimated average of 29.6% of birds were culled prior to roost abandonment. The roost culling effort was conducted during the COVID-19 pandemic, when tourist numbers and foot traffic were greatly reduced. It is unknown how public perception of roost culling in public areas may impact future efforts. Findings suggest roost culling can be utilized for management of nonnative rose-ringed parakeet populations when roost size is small enough and staff size large enough to cull entire roosts in no greater than two consecutive nights (e.g., if two shooters are available for three hours per night, roost culling should only be attempted on a roost with ≤ 540 rose-ringed parakeets).

Preliminary study evaluating the assessment of changes in pulmonary function associated with body positioning in dogs with suspected aspiration pneumonia.

OBJECTIVE: To evaluate the variability in arterial blood gas (ABG) assessment of pulmonary function with different body positioning in dogs with suspected aspiration pneumonia. KEY FINDINGS: The median differences in alveolar-arterial gradient, Pao2 , and Paco2 values in different recumbencies were not statistically significantly different, both within patients and across the study population. No difference was noted in ABG values in the subgroups with unilateral or bilateral disease or that were more affected on the right side versus the left side. SIGNIFICANCE: This preliminary study provides data that can be used to calculate appropriate sample sizes for subsequent studies investigating the impact of recumbency on pulmonary function in patients with aspiration pneumonia.

Nephrotoxic Exposures and Acute Kidney Injury in Noncritically Ill Children Stratified by Service.

OBJECTIVE: The Nephrotoxic Injury Negated by Just-in-Time Action (NINJA) program is a multicenter, quality improvement initiative that identifies patients at risk for nephrotoxic medication-associated acute kidney injury (NTMx-AKI). The purpose of this study was to (1) evaluate the prevalence and types of NTMx exposures and (2) determine the prevalence of NTMx-AKI categorized by service. Exploratory analysis evaluated potential associations between hospital measures and NTMx-AKI. METHODS: This is a single-center, retrospective chart review of NTMx exposures from January 2019 to June 2020 in noncritically ill children. High NTMx exposures were defined as ≥3 simultaneous nephrotoxins or ≥3 days of either intravenous vancomycin or aminoglycoside. Prevalence of high NTMx and NTMx-AKI rate were normalized to 1000 patient days. A retrospective case-control analysis assessed for potential associations with development of NTMx-AKI. RESULTS: There were 609 NTMx exposures in 565 patients and 44 (7.2%) episodes of NTMx-AKI. The NTMx prevalence rate per 1000 patient days was highest among liver, neurosurgery, and gastroenterology services. The most commonly used NTMx were vancomycin, intravenous contrast, and nonsteroidal antiinflammatory drugs. The NTMx-AKI rate in exposed patients ranged from 0% to 14% across service lines. AKI was most often attributable to vancomycin. Univariable analyses suggest type and duration of NTMx exposure are associated with development of NTMx-AKI but not with severity. CONCLUSIONS: NTMx exposures and NTMx-AKI are variable across services. Partnerships with antimicrobial stewardship and multicenter studies are needed to modify NTMx-AKI risk. Ongoing surveillance is needed in patients who do not have normalization of creatinine before discharge.

Safety profile of repeated infusion of platelet-like nanoparticles in healthy dogs.

OBJECTIVE: To assess the safety and efficacy of the platelet-like nanoparticle (PLN), and to assess its safety in repeated administration. ANIMALS: 6 purpose-bred dogs. PROCEDURES: The PLN was administered IV at 3 different doses using a randomized crossover design. Each dog received a full dose of 8 X 1010 particles/10 kg, half dose, and 10 times the dose, with a 14-day washout period between doses. Biochemical, prothrombin time, partial thromboplastin time, and fibrinogen analyses were performed at baseline and 96 hours postinfusion. A CBC, kaolin-activated thromboelastography, platelet function assay closure time, and buccal mucosal bleeding time were performed at baseline and 1, 6, 24, 48, 72, and 96 hours postinfusion. RESULTS: No significant changes were observed over time in the thromboelastography parameters, closure time, and buccal mucosal bleeding time. After the administration of the half dose, hematocrit levels decreased significantly at 1, 6, 24, 48, and 96 hours, with all values within the reference range. The platelet count was decreased significantly at hours 1, 6, 24, 48, and 72 after administration of the half dose, with values less than the reference range at all hours but hour 72. No significant changes in serum biochemistry, coagulation panel, and fibrinogen were observed for all doses. No adverse events were noted during the first infusion. Three dogs experienced transient sedation and nausea after repeat infusion. CLINICAL RELEVANCE: The PLN resulted in a dilution of hematocrit and platelets, and did not significantly alter hemostasis negatively. The safety of repeated doses should be investigated further in dogs.

Impact of cytidine diphosphocholine on oxygenation in client-owned dogs with aspiration pneumonia.

BACKGROUND: New drugs for veterinary patients with acute respiratory distress syndrome (ARDS) are urgently needed. Early or late postinfection treatment of influenza-infected mice with the liponucleotide cytidine diphosphocholine (CDP-choline) resulted in decreased hypoxemia, pulmonary edema, lung dysfunction, and inflammation without altering viral replication. These findings suggested CDP-choline could have benefit as adjunctive treatment for ARDS in veterinary patients (VetARDS). OBJECTIVES: Determine if parenterally administered CDP-choline can attenuate mild VetARDS in dogs with aspiration pneumonia. ANIMALS: Dogs admitted to a veterinary intensive care unit (ICU) for aspiration pneumonia. METHODS: Subjects were enrolled in a randomized, double-blinded, placebo-controlled trial of treatment with vehicle (0.1 mL/kg sterile 0.9% saline, IV; n = 8) or CDP-choline (5 mg/kg in 0.1 mL/kg 0.9% saline, IV; n = 9) q12h over the first 48 hours after ICU admission. RESULTS: No significant differences in signalment or clinical findings were found between placebo- and CDP-choline-treated dogs on admission. All dogs exhibited tachycardia, tachypnea, hypertension, hypoxemia, hypocapnia, lymphopenia, and neutrophilia. CDP-choline administration resulted in rapid, progressive, and clinically relevant increases in oxygenation as determined by pulse oximetry and ratios of arterial oxygen partial pressure (Pa O2 mmHg) to fractional inspired oxygen (% Fi O2 ) and decreases in alveolar-arterial (A-a) gradients that did not occur in placebo (saline)-treated animals. Treatment with CDP-choline was also associated with less platelet consumption over the first 48 hours, but had no detectable detrimental effects. CONCLUSIONS AND CLINICAL IMPORTANCE: Ctyidine diphosphcholine acts rapidly to promote gas exchange in dogs with naturally occurring aspiration pneumonia and is a potential adjunctive treatment in VetARDS patients.

Ten-year follow-up after mitoxantrone induction for early highly active relapsing-remitting multiple sclerosis: An observational study of 100 consecutive patients.

BACKGROUND: Six monthly courses of mitoxantrone were approved in France in 2003 for patients with highly active multiple sclerosis (MS). OBJECTIVE: To report the 10-year clinical follow-up and safety of mitoxantrone as an induction drug followed by maintenance therapy in patients with early highly active relapsing-remitting MS (RRMS) and an Expanded Disability Status Scale (EDSS) score<4, 12months prior to mitoxantrone initiation. METHODS: In total, 100 consecutive patients with highly active RRMS from the Rennes EDMUS database received monthly mitoxantrone 20mg combined with methylprednisolone 1g for 3 (n=75) or 6months (n=25) followed by first-line disease-modifying drug (DMD). The 10-year clinical impact was studied through clinical activity, DMD exposure, and adverse events. RESULTS: Twenty-four percent were relapse-free over 10years and the mean annual number of relapses was 0.2 at 10years. The mean EDSS score remained significantly improved for up to 10years, changing from 3.5 at mitoxantrone initiation to 2.7 at 10years. The probability of disability worsening and improvement from mitoxantrone initiation to 10years were respectively 27% and 58%, and 13% converted to secondary progressive MS. Patients only remained untreated or treated with a first-line maintenance DMD for 6.5years in average. In our cohort, mitoxantrone was generally safe. No leukemia was observed and six patients developed neoplasms, including 4 solid cancers. CONCLUSION: Monthly mitoxantrone for 3 or 6months, followed by maintenance first-line treatment, may be an attractive therapeutic option for patients with early highly active RRMS, particularly in low-income countries.

Developing tools to evaluate quality of care management for patients living with multiple sclerosis: An original French initiative.

INTRODUCTION: Assessing the quality of care management for patients with a chronic disease such as multiple sclerosis (MS) is a major challenge for healthcare systems around the world. It needs to be carried out using tools that are recognized by professionals and patients alike, and should concern practices, systems, and scientific data. No such tools are currently available in Europe. The purpose of the present study was to develop indicators to contribute to assess the quality of care management for patients with MS in France. METHODS: An expert panel comprising 25 professionals from well known teams across France selected the indicators on the basis of consensus. In accordance with the Rand/UCLA Appropriateness Method, each expert had to agree with the recommendations, and there had to be agreement among the experts. RESULTS: The expert panel selected 48 indicators representing seven domains of care management for patients with MS: physical and rehabilitation medicine, disease progression, access to care, magnetic resonance imaging (MRI) management, relapse management, management of disease-modifying treatments, and management of the symptoms of disability progression. Some of these quality indicators (notably pertaining to MRI management) had not previously been identified in the literature. CONCLUSION: These indicators may allow professionals to comprehensively assess and compare their practices and cooperation, thereby contributing to improve the quality of care management for patients with MS in France.

Maintenance of Wellness in Patients With Obsessive-Compulsive Disorder Who Discontinue Medication After Exposure/Response Prevention Augmentation: A Randomized Clinical Trial.

IMPORTANCE: Serotonin reuptake inhibitors (SRIs) are the only medications approved for obsessive-compulsive disorder (OCD), yet most patients taking SRIs exhibit significant symptoms. Adding exposure/response prevention (EX/RP) therapy improves symptoms, but it is unknown whether patients maintain wellness after discontinuing SRIs. OBJECTIVE: To assess whether patients with OCD who are taking SRIs and have attained wellness after EX/RP augmentation can discontinue their SRI with noninferior outcomes compared with those who continue their SRI therapy. DESIGN, SETTING, AND PARTICIPANTS: A 24-week, double-blind, randomized clinical trial was performed from May 3, 2013, to June 25, 2018. The trial took place at US academic medical centers. Participants included 137 adults with a principal diagnosis of OCD (≥1 year) who were taking an SRI (≥12 weeks), had at least moderate symptoms (defined as Yale-Brown Obsessive-Compulsive Scale [Y-BOCS] score ≥18 points), and received as many as 25 sessions of EX/RP therapy. Those who attained wellness (Y-BOCS score ≤14 points; 103 patients [75.2%]) were study eligible. Data were analyzed from June 29, 2019, to October 2, 2021. INTERVENTION: Participants were randomly assigned either to receive taper to placebo (taper group) or to continue their SRI (continuation group) and monitored for 24 weeks. MAIN OUTCOME AND MEASURES: The Y-BOCS score (range, 0-40 points) was the primary outcome; the Hamilton Depression Rating Scale (HDRS; range, 0-52 points) and the Quality-of-Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF; range, 0%-100%) scores were secondary outcomes. Outcomes were assessed at 8 time points by independent evaluators who were blinded to randomization. The taper regimen was hypothesized to be noninferior to continuation at 24 weeks using a 1-sided α value of .05. RESULTS: A total of 101 patients (mean [SD] age, 31.0 [11.2] years; 55 women [54.5%]) participated in the trial: 51 patients (50.5%) in the taper group and 50 patients (49.5%) in the continuation group. At 24 weeks, patients in the taper group had noninferior results compared with patients in the continuation group (mean [SD] Y-BOCS score: taper group, 11.47 [6.56] points; continuation group: 11.51 [5.97] points; difference, -0.04 points; 1-sided 95% CI, -∞ to 2.09 points [below the noninferiority margin of 3.0 points]; mean [SD] HDRS score: taper group, 5.69 [3.84] points; continuation group, 4.61 [3.46] points; difference, 1.08 points; 1-sided 95% CI, -∞ to 2.28 points [below the noninferiority margin of 2.5 points]; mean [SD] Q-LES-Q-SF score: taper group, 68.01% [15.28%]; continuation group, 70.01% [15.59%]; difference, 2.00%; 1-sided 95% CI, -∞ to 6.83 [below the noninferiority margin of 7.75]). However, the taper group had higher rates of clinical worsening (23 of 51 [45%] vs 12 of 50 [24%]; P = .04). CONCLUSIONS AND RELEVANCE: Results of this randomized clinical trial show that patients with OCD who achieve wellness after EX/RP therapy could, on average, discontinue their SRI with noninferior outcomes compared with those who continued their SRI. Those who tapered the SRI had higher clinical worsening rates. Future research should evaluate if SRI half-life alters these rates. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01686087.

Developing a predictive model for spinal shock in dogs with spinal cord injury.

BACKGROUND: Reduced pelvic limb reflexes in dogs with spinal cord injury typically suggests a lesion of the L4-S3 spinal cord segments. However, pelvic limb reflexes might also be reduced in dogs with a T3-L3 myelopathy and concurrent spinal shock. HYPOTHESIS/OBJECTIVES: We hypothesized that statistical models could be used to identify clinical variables associated with spinal shock in dogs with spinal cord injuries. ANIMALS: Cohort of 59 dogs with T3-L3 myelopathies and spinal shock and 13 dogs with L4-S3 myelopathies. METHODS: Data used for this study were prospectively entered by partner institutions into the International Canine Spinal Cord Injury observational registry between October 2016 and July 2019. Univariable logistic regression analyses were performed to assess the association between independent variables and the presence of spinal shock. Independent variables were selected for inclusion in a multivariable logistic regression model if they had a significant effect (P ≤ .1) on the odds of spinal shock in univariable logistic regression. RESULTS: The final multivariable model included the natural log of weight (kg), the natural log of duration of clinical signs (hours), severity (paresis vs paraplegia), and pelvic limb tone (normal vs decreased/absent). The odds of spinal shock decreased with increasing weight (odds ratio [OR] = 0.28, P = .09; confidence interval [CI] 0.07-1.2), increasing duration (OR = 0.44, P = .02; CI 0.21-0.9), decreased pelvic limb tone (OR = 0.04, P = .003; CI 0.01-0.36), and increased in the presence of paraplegia (OR = 7.87, P = .04; CI 1.1-56.62). CONCLUSIONS AND CLINICAL IMPORTANCE: A formula, as developed by the present study and after external validation, could be useful for assisting clinicians in determining the likelihood of spinal shock in various clinical scenarios and aid in diagnostic planning.

Evaluation of the quality of the care pathway for patients with multiple sclerosis in France: Results of an original study of a cohort of 700 patients.

INTRODUCTION: Evaluating the quality of the care pathway for patients with chronic diseases, such as multiple sclerosis (MS), is an important issue. Process indicators are a recognized method for evaluating professional practices. However, these tools have been little developed in the field of MS, and few data are available. The aim of this study was to describe, retrospectively, with validated indicators, the quality of the care pathway in a population-based cohort of 700 patients with the first manifestations of the disease occurring between January 1, 2000 and December 31, 2001 and during the first 10 years of disease. METHOD: This assessment was based on 48 indicators specific to MS. The information required for the calculation of each indicator was collected from the source files of the 700 patients of the cohort. RESULTS: Data for the 10 years of follow-up were collected for 80% of the patients. In total, 36 indicators were calculated. These results reveal that there is room for improvement, particularly in terms of the initial assessment, access to ophthalmological evaluation, employment, obtaining an evaluation of the need for rehabilitation and access to such care. CONCLUSION: The results of this survey provide access to unprecedented new data in France, that professionals and patients can appropriate to improve the targeting of actions, to improve the quality of care further for patients with MS in France. We propose to continue this process by submitting, for discussion, a targeted list of updated indicators relating to changes in guidelines, and in issues concerning the quality of patient management.
