Impact of the healthcare reorganization of the Local Health Authority services in Rieti (Italy) during the SARS-CoV-2 pandemic.

Background: The need to contain the spread of the SARS-CoV-2 pandemic has forced national and local organizations to define and implement targeted emergency response and management measures. As the knowledge about the infection grew, a wider range of organizational measures were deployed. Methods: This study involves the SARS-CoV-2 infected people managed by the Local Health Authority of Rieti (Italy). Diagnostic test waiting times and hospital admission rates in the Province of Rieti are investigated as the pandemic evolved. Trends were analyzed in relation to the tempora spreading of SARS-CoV-2, to the organizational actions taken by the Local Health Authority of Rieti, and to the deployment of actions across the territory. A municipalities classification of the province of Rieti was conducted after a cluster analysis based on the diagnostic test waiting times and the hospital admission rates. Results: Our findings show a declining trend, thus indicating a possible positive effect of the measures taken to contain the pandemic. The cluster analysis of the municipalities of the Province of Rieti makes evident an inhomogeneous geographical distribution of examined parameters (diagnostic test waiting times and the hospital admission rates), demonstrating the capability of Local Health Authority of Rieti to reach even the most disadvantaged areas and implying that the differences are due to the demographical variabilities. Conclusion: Despite some limitations, this study outlines the importance of management measures in response of the pandemic. These measures should adapt to social, cultural and geographical nature of the territory involved. The findings of the present study will contribute to the update of further pandemic preparedness plans of the Local Health Authorities.

KRD (carfilzomib and lenalidomide plus dexamethasone) for the treatment of relapsed or refractory multiple myeloma in the real-life: a retrospective survey in 123 patients.

From April 2016, carfilzomib, in combination with lenalidomide and dexamethasone (KRD), became available for use in the daily practice in Italy for patients with relapsed or refractory multiple myeloma (RRMM). We performed a retrospective survey at 14 different institutions from Southern Italy in order to evaluate patient characteristics and treatment results from an unselected series of patients treated accordingly so far. One hundred and twenty-three consecutive patients were included, with a median of 2 previous lines of therapy (range 1-9) and a median age of 63 years (range 39-82). At the time of analysis, median number of courses administered is 11 (range 1-34), and all patients are evaluable for response. Overall response rate including complete remission, very good partial remission, and partial remission is 85%. After a median follow-up of 27 months, median overall and progression-free survival are 33 and 23 months, respectively. Sixty-three patients are alive and between them, 45 (37%) are in continuous remission. Sixty patients have died (49%), mainly from progressive disease. There were 6 treatment-related deaths (5% of the whole patient population). Overall, hematological and non-hematological toxicity were manageable, mostly on outpatient basis. Arterial hypertension has been observed in 43 cases (35%) but did not lead to treatment interruption. Our data demonstrate that in real life, KRD is highly effective and well tolerated in the majority of patients with RRMM.

[COP21 - Organization and activity of a medical cover under "pressure"]. / COP21 ­ Organisation et bilan d'une médicalisation sous haute tension.

INTRODUCTION: The United Nations Climate Conference (COP21) gathered in France for delegations from all around the world, with 20,000 delegates from 195 countries every day, including 150 heads of states during the first 48hours. A specific medical cover was organized in a particular "post-attacks" context and with harsh constraints due to delimitation of an inner zone under the sole UN authority ("blue zone"). OBJECTIVE: To evaluate medical means involved and medical activity. METHODS: Medical cover was managed by SAMU 93 in collaboration with zonal SAMU and regional health agency for the entire site including the "blue zone". End-points: engaged workforce, number of visits, including transfers and medicalized transfers. RESULTS: In "France zone" (operational headquarters): an emergency physician dispatcher and an assistant for 20 days. In "blue zone": 20 rescuers, mobile intensive care unit H24 and two emergency physicians (consultations) 12/24hours for 16 days. A total of 47 doctors, 25 nurses, 25 paramedics and 20 assistants participated in the medical service. This corresponded to three emergency physician full medical time equivalents (FMTE) for 16 days. Consultations performed: 1238 or 97/day resulting in 34 (3%) transfers including seven medicalized. Patients were 706 (57%) men and 495 (43%) women, with mean age of 43±1 years. Trauma patients were most numerous (20%). CONCLUSION: Medical means involved were consistent for 16 days. The medical activity was sustained, but medicalized transfer rarely required.

Genetic landscape of ultra-stable chronic lymphocytic leukemia patients.

Background: Chronic lymphocytic leukemia (CLL) has a heterogeneous clinical course. Beside patients requiring immediate treatment, others show an initial indolent phase followed by progression and others do not progress for decades. The latter two subgroups usually display mutated IGHV genes and a favorable FISH profile. Patients and methods: Patients with absence of disease progression for over 10 years (10-34) from diagnosis were defined as ultra-stable CLL (US-CLL). Forty US-CLL underwent extensive characterization including whole exome sequencing (WES), ultra-deep sequencing and copy number aberration (CNA) analysis to define their unexplored genetic landscape. Microarray analysis, comparing US-CLL with non-US-CLL with similar immunogenetic features (mutated IGHV/favorable FISH), was also carried out to recognize US-CLL at diagnosis. Results: WES was carried out in 20 US-CLL and 84 non-silent somatic mutations in 78 genes were found. When re-tested in a validation cohort of 20 further US-CLL, no recurrent lesion was identified. No clonal mutations of NOTCH1, BIRC3, SF3B1 and TP53 were found, including ATM and other potential progression driving mutations. CNA analysis identified 31 lesions, none with known poor prognostic impact. No novel recurrent lesion was identified: most cases showed no lesions (38%) or an isolated del(13q) (31%). The expression of 6 genes, selected from a gene expression profile analysis by microarray and quantified by droplet digital PCR on a cohort of 79 CLL (58 US-CLL and 21 non-US-CLL), allowed to build a decision-tree capable of recognizing at diagnosis US-CLL patients. Conclusions: The genetic landscape of US-CLL is characterized by the absence of known unfavorable driver mutations/CNA and of novel recurrent genetic lesions. Among CLL patients with favorable immunogenetics, a decision-tree based on the expression of 6 genes may identify at diagnosis patients who are likely to maintain an indolent disease for decades.

Very Early Carotid Endarterectomy After Intravenous Thrombolysis.

OBJECTIVE/BACKGROUND: The timing of carotid endarterectomy (CEA) after thrombolysis is still a matter of debate. The aim of this study was to analyse a cohort of patients undergoing urgent endarterectomy after intravenous thrombolysis for acute ischaemic stroke. METHODS: This was an observational study. Prospective databases were reviewed and matched to identify patients who underwent CEA early after intravenous thrombolysis (2009-14). The focus was carotid surgery performed within 12 hours of stroke onset in patients with a high grade (≥70%) symptomatic carotid stenosis, associated with vulnerable plaques or stroke in evolution, and evidence of a significant salvageable ischaemic penumbra on perfusion computed tomography scan. Demographic and clinical information, as well as data on relevant outcomes were extracted. RESULTS: Thirty four consecutive stroke patients who underwent CEA within 2 weeks of thrombolysis for acute ischaemic stroke and ipsilateral high grade carotid stenosis were identified. In 11 patients the surgical procedure was performed within 12 hours of the onset of symptoms. All patients showed a clinical improvement after combined treatment. The 3 month outcome was favourable (modified Rankin Scale ≤ 2) in 10 patients. No haemorrhagic complications were registered. There was neither peri-operative stroke nor stroke within 3 months of surgery. One patient died from acute myocardial infarction 3 days after intervention. CONCLUSION: This experience suggests that very early CEA after thrombolysis, aimed at removing the source of potential embolisation and restoring blood flow, may be safe and can lead to a favourable outcome.

Appearance of fetal posterior fossa at 11-14 weeks in fetuses with Dandy-Walker malformation or chromosomal anomalies.

OBJECTIVE: To describe the sonographic appearance of fetal posterior fossa anatomy at 11-14 weeks of pregnancy and to assess the outcome of fetuses with increased intracranial translucency (IT) and/or brainstem-to-occipital bone (BSOB) diameter. METHODS: Reference ranges for brainstem (BS), IT and cisterna magna (CM) measurements, BSOB diameter and the BS : BSOB ratio were obtained from the first-trimester ultrasound examination of 233 fetuses with normal postnatal outcome (control group). The intraobserver and interobserver variability of measurements were investigated using 73 stored ultrasound images. In addition, a study group of 17 fetuses with increased IT and/or BSOB diameter was selected to assess outcome. RESULTS: No significant intraobserver or interobserver variability was found for any measurement in the control group. In the study group, IT was increased in all cases and BSOB diameter was above the 95(th) centile of the calculated normal range in all but two (88%) cases. In 13/17 study cases, only two of the three posterior brain spaces were recognized on ultrasound. These 13 fetuses had a larger BSOB diameter than did the four cases that showed all three posterior brain spaces, and had severe associated anomalies including Dandy-Walker malformation (DWM) and/or chromosomal anomalies. CONCLUSIONS: Visualization of the fetal posterior fossa anatomy at 11-14 weeks' gestation is feasible. Increased fluid in the posterior brain at 11-14 weeks, particularly in the case of non-visibility of the septation that divides the future fourth ventricle from the CM, is an important risk factor for cystic posterior fossa malformations, in particular DWM, and/or chromosomal aberrations.

Optical field-enhancement and subwavelength field-confinement using excitonic nanostructures.

We show that dye-doped polymers open an interesting route to controlling light at the nanoscale. Just as for the much better known metal-based plasmonic systems, propagating and localized modes are possible. We show that the attractive features offered by plasmonics, specifically enhanced optical fields and subwavelength field confinement, are also available with these materials. They thus open a new opportunity in nanophotonics in which fabrication and functionality might be achieved by harnessing molecular and supramolecular chemistry.

A(2A) adenosine receptors and Parkinson's disease severity.

OBJECTIVES: In the last decade, increasing evidence suggests a key role of adenosine in Parkinson's disease (PD) and A2A adenosine receptors (A2A ARs) as an important pharmacological target in PD. An overexpression of A2A ARs has been found in putamen and in peripheral blood cells of PD patients. The primary aim of this study was to verify whether the alterations in A2A ARs in lymphocytes of PD subjects correlate with disease severity. MATERIAL AND METHODS: A consecutive sample of PD patients was enrolled. A clinical examination and a face-to-face interview were carried out. A2A ARs were investigated to verify the affinity and receptor density in lymphocyte membranes. The data were compared with those found in healthy controls. Moreover, the correlation between A2A AR density and affinity and clinical variables was evaluated in PD patients. RESULTS: In human lymphocyte membranes from PD patients, an increase in A2A AR density and a decrease in A2A AR affinity were found if compared with healthy subjects. A statistically significant correlation between the A2A AR density or affinity and specific clinical parameters as motor and cognitive impairment was detected. Patients with higher A2A AR density and lower affinity were more likely to exhibit motor complications. CONCLUSIONS: Parkinson's disease patients show an A2A AR upregulation in lymphocyte membranes if compared with healthy subjects. The correlation found between A2A AR density or affinity and clinical parameters highlights the central role of A2A AR modulation in the pharmacological treatment for PD and could suggest the putative role of A2A AR as a candidate biomarker of PD severity.

Plasma creatinine levels, estimated glomerular filtration rate and carotid intima media thickness in middle-aged women: a population based cohort study.

BACKGROUND AND AIM: The relationships between high Creatinine (Cr) levels or low estimated Glomerular Filtration Rate (eGFR) and common carotid Intima Media thickness (IMT) have been evaluated in a population-based cohort study in women, aged 30-69 (Progetto ATENA). METHODS AND RESULTS: Serum Cr and eGFR were measured in 310 women, as a part of 5.062. In this group carotid ultrasound examination (B-Mode imaging) was performed and mean max IMT was calculated. Women were classified by Cr levels >1 mg/dL or eGFR < 56 ml/min. Women with Cr > 1 mg/dL (90th percentile of creatinine distribution) or eGFR less than 56 ml/min (5th percentile of eGFR distribution) had relatively more carotid plaques as compared to the rest of the cohort. Multivariate logistic analysis, after adjustment for age, demonstrated a significant association between Cr (>1 mg/dL) and IMT (≥1.2 mm): OR 4.12 (C.I 1.22-13.86), p = 0.022; or eGFR (<56 ml/min) and IMT (≥1.2 mm): OR 4.31 (C.I 1.27-14.66), p = 0.019. CONCLUSIONS: These findings on an independent relationship between Cr and common carotid plaques in this population of middle aged women, independently of age, suggest the value of screening for early carotid disease in asymptomatic middle aged-women with mild renal insufficiency, in order to predict those at relatively higher risk for future cardiovascular events.

Treatment of fistula in ano with fibrin glue: preliminary results from a prospective study.

AIM: This prospective study was done to evaluate the efficacy of commercial fibrin glue application in the healing of patients with fistulas-in-ano from a short follow up period (one year). METHODS: This randomized clinical trial of 26 patients was performed during the period from January 2012 to July 2012. Nineteen men and seven women were treated for a fistula-in-ano with a commercial fibrin glue injection. In the operating room, the patients underwent an anorectal examination under spinal anesthesia. The external and internal fistula tract openings were then identified and the fistula tract was accurately curetted. Fibrin glue was introduced by a loaded double-channel syringe into the external fistula opening until the fibrin glue tip could be seen emerging from the internal opening. RESULTS: The initial success rate was 76.9% (20/26). Recurrence rate was 23% (6/26). Four patients underwent a re-application of fibrin glue and the fistulas of these patients closed. Total recurrence rate was 7.6% (2/26). The overall success rate was 69.2% (18/26). CONCLUSION: Fibrin glue application was thus found to be an easy, safe, successful alternative treatment in the management of fistulas-in-ano. Specifically, this therapeutic option demonstrated his efficacy for simple non-ramificated transsphincteric and intersphincteric fistulas. Multicentric randomized clinical trials with more representative sample seem to be necessary to investigate the best patients to treat by fibrin glue injection and the optimal application technique to improve these results.

Assessing the appropriateness of the level of care for morbidly obese subjects: validation of the CASCO-R scale.

AIM: Aim of this study was to validate the Comprehensive Appropriateness Scale for the Care of Obesity in Rehabilitation (CASCO-R) and to determine the cut-off score for indicating the most appropriate health care setting for patients with obesity. METHODS: The CASCO-R scale was developed according to the available scientific literature and expertise of an expert panel working for a Consensus document endorsed by the Italian Society of Obesity (SIO) and the Italian Society for the Study of Eating Disorders (SISDCA). 16 Italian centres, specialized in the treatment of obesity, characterised by different settings of care (specialist outpatient service, day-hospital service, intensive inpatient rehabilitation), participated in the study. RESULTS: 449 obese subjects were enrolled in the study (30.5% males and 69.5% females): 38.3% from outpatient services, 20.7% from day-hospital services and 40.9% from intensive inpatient rehabilitation units. After 2-month of treatment, a workload summary sheet, including medical and nursing interventions, number of expert advices and diagnostic procedures, and adverse clinical events (ACEs) was fulfilled for each patient. Statistically significant correlation was found between the CASCO-R scale score, overall workload and ACEs. The CASCO-R scale demonstrated also an excellent performance in terms of internal validity and test-retest analysis. Three total score cut-off have been proposed: >25 for inpatient intensive rehabilitation; 20-25 for day-hospital service; <20 for outpatient treatment. CONCLUSIONS: In conclusion, the CASCO-R scale was demonstrated to be a valid tool for assessing the appropriateness of the choice of the level of care. Hence, it can be used to verify the proper allocation of patients, as it was well correlated with measures of workload and the incidence of ACEs.

Outcome of lumbar intervertebral foraminal stenosis surgery and depression.

A total of 58 patients consecutively underwent surgical treatment for lumbar intervertebral foraminal stenosis. We performed a microsurgical combined transarticular lateral and medial procedure with partial facetectomy in all patients to decompress the affected nerve root. All patients underwent assessment of depressive symptoms by means of the Zung Self Depression Scale (SDS). Subjective pain was self-evaluated by the Visual Analogue Scale (VAS). Both the tools were administered preoperatively, at 3 and 12 months' follow-up 0. The difference between the three SDS scores was significant (Friedman ANOVA, χ(2) = 53.171, p < 0.00001). The Wilcoxon rank test showed significant difference between preoperative SDS scores as compared with three months follow-up (Z = -6.393, p < 0.0001) and the last, in turn, as compared with twelve months follow- up (Z = -3.720, p = 0.0002). The comparison between preoperative and 12 months' follow-up also reached significance (Z = -3.285, p = 0.001). About VAS, the difference between the three VAS scores was significant (Friedman ANOVA, χ(2) = 69.932, p < 0.00001). The Wilcoxon rank test showed significant difference between preoperative VAS scores as compared with 3 months' follow-up (Z = -6.567, p < 0.0001) and the last, in turn, as compared with 12 months' follow-up (Z = -3.153, p < 0.002). The comparison between preoperative and 12 months' follow-up was also significance (Z = -5.520, p < 0.0001). Our results would alert clinicians to accurately consider the real need to treat and to include a careful psychiatric and psychological evaluation of these patients in the diagnosis and follow-up 0.

Imiquimod 5% cream versus cold knife excision for treatment of VIN 2/3: a five-year follow-up.

BACKGROUND: Vulvar intraepithelial neoplasia (VIN) is a premalingnant condition. For long time, surgery was considered the first-line therapy in the treatment of high grade VIN. Imiquimod was recently introduced as an alternative to surgery. AIM: To compare the overall complete response, the recurrence rate and the risk factors for relapse among patients with VIN 2/3 treated with Imiquimod or surgical excision. PATIENTS AND METHODS: Eighty women who had histological diagnosis of VIN 2 and VIN 3 were enrolled in this prospective study. Patients immunocompromised, with recurrent VIN, with well differentiated type VIN or VIN 1 and women treated more than once were excluded from the study. Patients were divided into two groups: group A was treated with Imiquimod, group B underwent surgical excision. Patients' characteristics analyzed were: age, smoking, degree of the primary lesion, state of margins, multifocal disease. We have evaluated the recurrence rate, the relapse rate, and the overall complete response, considering as recurrence the onset of a lesion after an initial complete response to Imiquimod and/or after the surgical treatment and as relapse all patients who had a recurrence plus those with medical treatment failure. RESULTS: Multifocal lesions (p = 0.03) and VIN 3 (p = 0.002) were associated with a higher risk of relapse. The recurrence rate was higher in the group B (p = 0.009), but the relapse rate was higher in the group A (p = 0.04). The overall complete response was better in the group B (p = 0.04). CONCLUSIONS: Although the advent of new medical options can decrease the morbidity associated with invasive surgical procedures, surgical treatments remain the best treatment modality for VIN with regard to relapse and overall complete response.

Multiple lymphomatous polyposis with diffuse involvement of the gastrointestinal tract. Case report.

The gastrointestinal tract is the predominant site of extranodal non-Hodgkin lymphomas. Multiple lynphomatous polyposis is a type of appearance of mantle cell lymphoma. It is characterized by multiple polypoid lesions involving long gastrointestinal tracts and it accounts for only approximately 1-2% of non-Hodgkin lymphomas. A 78 years old patient was admitted to our Department of General Surgery with rectal bleeding, abdominal pain and weight loss. Multiple lymphomatous polyposis was detected by endoscopy. Endoscopic biopsies confirmed the diagnosis of mantle cell lymphoma. The patient was transferred to the Department of Hematology for cycles of chemotherapy.

Microarray application in prenatal diagnosis: a position statement from the cytogenetics working group of the Italian Society of Human Genetics (SIGU), November 2011.

A precise guideline establishing chromosomal microarray analysis (CMA) applications and platforms in the prenatal setting does not exist. The controversial question is whether CMA technologies can or should soon replace standard karyotyping in prenatal diagnostic practice. A review of the recent literature and survey of the knowledge and experience of all members of the Italian Society of Human Genetics (SIGU) Committee were carried out in order to propose recommendations for the use of CMA in prenatal testing. The analysis of datasets reported in the medical literature showed a considerable 6.4% incidence of pathogenic copy number variations (CNVs) in the group of pregnancies with sonographically detected fetal abnormalities and normal karyotype. The reported CNVs are likely to have a relevant role in terms of nosology for the fetus and in the assessment of reproductive risk for the couple. Estimation of the frequency of copy number variations of uncertain significance (VOUS) varied depending on the different CMA platforms used, ranging from 0-4%, obtained using targeted arrays, to 9-12%, obtained using high-resolution whole genome single nucleotide polymorphism (SNP) arrays. CMA analysis can be considered a second-tier diagnostic test to be used after standard karyotyping in selected groups of pregnancies, namely those with single (apparently isolated) or multiple ultrasound fetal abnormalities, those with chromosomal rearrangements, even if apparently balanced, and those with supernumerary marker chromosomes.

Aberrant right subclavian artery (ARSA) in unselected population at first and second trimester ultrasonography.

OBJECTIVES: To evaluate the feasibility of examining aberrant right subclavian artery (ARSA) at first and second trimester gestation, its prevalence and associations in an unselected population. METHODS: Right subclavian artery (RSA) was prospectively evaluated in 6617 routine patients. When ARSA was detected, fetal echocardiography was offered and fetal karyotyping was discussed. If invasive testing was performed with normal karyotype, fluorescence in situ hybridization for 22q11.2 microdeletion and additionally, in case of nuchal translucency (NT) measurement above the 99(th) centile, oligo array-based comparative genomic hybridization, were offered. In all aneuploidies, NT and first trimester additional ultrasonographic (US) markers assessment (nasal bone, tricuspid valve, ductus venosus) were recorded. RESULTS: RSA assessment was feasible in 85.3% and 98% of first and second trimester examinations, respectively (overall feasibility 94%). There were detected 89 ARSA (1.42% of the feasible cases), of which 66 in the first trimester. More than 20% were associated to other abnormalities: 10 aneuploidies; 2 microdeletions (15q11.2 and 22q11.2); in the euploid fetuses, 8 associated abnormalities were observed, 4 of which were cardiac defects. In the case of 22q11.2 microdeletion, ARSA was associated only with increased NT. CONCLUSION: Prenatal routine US assessment of the RSA is feasible by highly experienced operators in first trimester screening. There is an important association of ARSA detected in unselected population with fetal abnormalities, including aneuploidies, cardiac defects and genetic anomalies. In trisomy 21 fetuses, ARSA can be the only first trimester US marker or, when associated to increased NT, it can represent the only 'additional' marker.

Evaluation of E6 and E7 mRNA expression in HPV DNA positive breast cancer.

Several studies have suggested a possible role for HPV in the pathogenesis of the breast cancer. We investigated the presence of the HPV DNA in breast cancers and non malignant disease breast tissues by the use of a standard HPV detection method (INNO-Lipa HPV), in order to detect HPV DNA in metastatic nodes, to investigate a possible cervical HPV co-infection, and to evaluate the E6/E7 mRNA expression in HPV DNA positive breast cancer tissues. The rate of HPV infection was significantly higher in the cancer group than in controls (9/31 vs. 0/12, p = 0.04). One out of eight metastatic axillary nodes was positive for HPV infection; 2/3 of the positive HPV breast cancer patients were co-infected at the cervical site. The role of the virus in breast oncogenesis is still unclear, since our analysis failed in demonstrating the expression of viral E6 and E7 in positive HPV positive breast tumor tissues.

Combining PARP inhibition and immune checkpoint blockade in ovarian cancer patients: a new perspective on the horizon?

Immune checkpoint inhibitors (ICIs) have completely reshaped the treatment of many malignancies, with remarkable improvements in survival outcomes. In ovarian cancer (OC), however, this emerging class of drugs has not yet found a favorable use due to results from phase I and II studies, which have not suggested a substantial antitumoral activity of these agents when administered as monotherapy. Robust preclinical data seem to suggest that the combination ICIs with poly(ADP-ribose) polymerase (PARP) inhibitors (PARPis) may result in a synergistic activity; furthermore, data from phase II clinical studies, evaluating this combination, have shown encouraging outcomes especially for those OC patients not suitable for platinum retreatment. While waiting for ongoing phase III clinical trial results, which will clarify the role of ICIs in combination with PARPis in the newly diagnosed OC, this review aims to summarize the preclinical data and clinical evidence available to date.

Polystyrene nanoplastics affect the human ubiquitin structure and ubiquitination in cells: a high-resolution study.

Humans are estimated to consume several grams per week of nanoplastics (NPs) through exposure to a variety of contamination sources. Nonetheless, the effects of these polymeric particles on living systems are still mostly unknown. Here, by means of CD, NMR and TEM analyses, we describe at an atomic resolution the interaction of ubiquitin with polystyrene NPs (PS-NPs), showing how a hard protein corona is formed. Moreover, we report that in human HeLa cells exposure to PS-NPs leads to a sensible reduction of ubiquitination. Our study overall indicates that PS-NPs cause significant structural effects on ubiquitin, thereby influencing one of the key metabolic processes at the base of cell viability.

Outcomes after reperfusion therapies in patients with ACA stroke: A multicenter cohort study from the EVATRISP collaboration.

BACKGROUND: Patients with stroke secondary to occlusions of the anterior cerebral artery (ACA) often have poor outcomes. The optimal acute therapeutic intervention for these patients remains unknown. METHODS: Patients with isolated ACA-stroke were identified from 10 centers participating in the EndoVascular treatment And ThRombolysis in Ischemic Stroke Patients (EVATRISP) prospective registry. Patients treated with endovascular thrombectomy (EVT) were compared to those treated with intravenous thrombolysis (IVT). Odds ratios with 95% confidence intervals (OR; 95%CI) were calculated using multivariate regression analysis. RESULTS: Included were 92 patients with ACA-stroke. Of the 92 ACA patients, 55 (60%) were treated with IVT only and 37 (40%) with EVT (±bridging IVT). ACA patients treated with EVT had more often wake-up stroke (24% vs. 6%, p = 0.044) and proximal ACA occlusions (43% vs. 24%, p = 0.047) and tended to have higher stroke severity on admission [NIHSS: 10.0 vs 7.0, p = 0.054). However, odds for favorable outcome, mortality or symptomatic intracranial hemorrhage did not differ significantly between both groups. Exploration of the effect of clot location inside the ACA showed that in patients with A1 or A2/A3 ACA occlusions the chances of favorable outcome were not influenced by treatment allocation to IVT or EVT. DISCUSSION: Treatment with either IVT or EVT could be safe with similar effect in patients with ACA-strokes and these effects may be independent of clot location within the occluded ACA.
