Abstract
OBJECTIVES To assess acute lipid profiles, atrial fibrillation and other cardiovascular risk factors in patients undergoing treatments by thrombectomy (EVT) with acute ischemic stroke (AIS). METHODS We performed a retrospective analysis of the lipid profile and vascular risk factor in 1639 consecutive patients with acute ischemic stroke between January 2016 and December 2021. To assess lipid profiles, laboratory tests, including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG), were obtained the day after admission. We also examined assessed the association between lipid profile, AF and EVT in multivariate logistic regression analysis. RESULTS Median age of patients was 74 years, 54.9% were males (95% CI 52.5-57.4%), and 26.8% (95% CI, 24.7-29.0%) had AF. EVT patients (n= 370; 22.57 %; 95% CI, 20.6-24.7) showed no difference in age (median 73 years [IQR; 63-80 ] versus 74 years [ QR; 63-82+ HbA1c levels (median 5.8 [IQR; 5.4-6.2] versus 5.9 [ IQR; 5.4-6.4+TG/HDL ratio (median 2.40 [IQR; 1.65-3.48#43; versus[IQR; 1.73-3.64)] diabetes (OR 0.82; 95% CI 0.61 to 1.08), hypertension (OR 0.87; 95% CI 0.68 to 1.12) and obesity (OR 1.06; 95% CI 0.78 to 1.42) compared to non-EVT patients. Conversely, EVT patients showed lower levels of TC (160 mg/dl[ IQR;139-187] versus 173 mg/dl [ IQR;148-202] P <0.001), LDL-C (105 mg/dl [ IQR; 80-133] versus 113 mg/dl [ IQR; 88-142] ; P <0.01), TG (98 mg/dl [ IQR; 76-126] versus 107 mg/dl [ IQR; 85-139] P <0.001), non-HDL-C (117 mg/dl[ IQR; 94-145] versus 127 mg/dl [ IQR; 103-154] P <0.001), HC (8.3[ mol/l [ IQR; 6-11] versus 10 µ mol/l[ IQR; 7.3-13.5] P <0.001) than non-EVT patients. Multivariate logistic regression analysis showed an independent association of EVT with TC (OR 0.99, 95% CI 0.98-0.99), AF (OR 1.79, 95% CI 1.34-2.38), age (OR 0.98, 95% CI 0.96-0.99), and NIHSS (OR 1.17, 95% CI 0.14-1.19). CONCLUSION Total cholesterol and all cholesterol-related measures were significantly lower in patients undergoing thrombectomy than in other stroke patients. Conversely, we found that AF was significantly high in patients with EVT, suggesting that hypercholesterolemia could be mainly linked to small-vessel occlusion stroke while large vessel occlusion (LVO) stroke could show different causes. AIS patients may have different pathogenesis and their understanding may improve enhance the discovery of specific and tailored preventive treatments.

Abstract
OBJECTIVE The aetiologic diagnosis of non-traumatic acute myelopathies (AMs), and their differentiation from other mimicking conditions (i.e. 'mimics'), are clinically challenging, especially in the emergency setting. Here, we sought to identify: (i) red flags suggesting diagnoses alternative to AMs and (ii) clinical signs and magnetic resonance imaging (MRI) features differentiating non-compressive from compressive AMs. MATERIALS AND METHODS We retrospectively retrieved MRI scans of spinal cord dictated at emergency room from January 2016 to December 2020 in the suspicion of AMs. Patients with traumatic myelopathies and those with subacute/chronic myelopathies (i.e. MRI scans acquired >48 h from symptom onset) were excluded from analysis. RESULTS Our search retrieved 105 patients; after excluding 16 cases of traumatic myelopathies and 14 cases of subacute/chronic myelopathies, we identified 30 cases with non-compressive AMs, 30 cases with compressive AMs and 15 mimics. The presence of pyramidal signs (p = 0.012) and/or pain (p = 0.048) correctly identified 88% of cases with AMs. We failed to identify clinical indicators for distinguishing non-compressive and compressive AMs, although cases with inflammatory AMs were younger than cases with all the remaining conditions (p < 0.05). Different MRI patterns could be described according to the final diagnosis: among non-compressive AMs, inflammatory lesions were more often posterior or central; vascular malformation had a fairly widespread distribution; spine ischaemia was more often central. Anterior or lateral compression were more often associated with neoplasms and disc herniation , whereas hemorrhages and infections produced spine compression on all sides. CONCLUSION We propose a simple clinical indicator (i.e. pyramidal signs and/or pain) to distinguish AMs from their mimics in an emergency setting. Urgent spinal cord MRI remains essential to discriminate compressive and non-compressive aetiologies.

Abstract
Abstract
Study question
To evaluate different embryo culture times (day5 versus day6) to understand the ideal time-frame for the performance of concordance analysis between invasive and non-invasive PGT-A(niPGT-A)
Summary answer
Different levels of ploidy concordance rates were observed between day5 and day6 groups: 72,6% versus 84,8%, respectively
What is known already
The recent data supports that a non-invasive approach for evaluating embryo ploidy status may be an alternative to standard invasive methods. Embryo cell-free DNA(cfDNA) released into culture media during in-vitro embryo development represents the potential source for this analysis. The release of cfDNA from embryos is expected to be directly proportional to embryo culture time and late-stage released cfDNA may be more representative of the embryo. Therefore, it is important to estimate the most effective time frame of the culture that will provide the most conclusive data from spent-culture-media(SCM) without adversely affecting the development of the embryo
Study design, size, duration
A total of 334 SCM from blastocyst stage embryos have been included in this study. The SCM samples were divided in 2 subgroups according to the embryo culture time as day5 (n = 154) and day6 (n = 180). The cfDNA of SCM samples were amplified by whole genome amplification(WGA) and analyzed by next generation sequencing(NGS) in parallel to day5 or day6 trophectodermal(TE) biopsied samples of their corresponding embryos. Ploidy status and concordance were compared between two groups
Participants/materials, setting, methods
Day3 embryos were washed and transferred in 20µl fresh culture media until the biopsy. SCM samples were collected in PCR tubes and stored at -20 °C while embryos were biopsied for standard PGT-A analysis. Both SCM and corresponding TE biopsy samples were amplified by Sureplex(Vitrolife). Then TE and SCM samples were analyzed by next-generation sequencing(NGS) using MiSeq® System (Illumina). Data analysis has been done by Bluefuse Multi Software 4.5(Illumina) for all SCM and TE samples
Main results and the role of chance
A successful DNA amplification rate (>30ng/µl) was obtained in both day5 and day6 groups with 95,5% (147/154) and 99,4% (179/180) respectively. The DNA concentration after WGA was ranging between 30.1-122.5ng/µl and 38.5-123.2ng/µl in day5 and day6 groups respectively. Not conclusive (NC) results including a noisy NGS profile and chaotic chromosome aneuploidies (>5 chromosomes) were excluded in both groups. Therefore, 64,6% (95/147) of SCM samples in day5 group and 81,0% (145/179) of SCM samples in day6 group were conclusive for NGS analysis. The ploidy concordance rate between SCM and TE samples (euploid vs euploid, aneuploid vs aneuploid) was 72,6% (69/95) in day5 and 84,8% (123/145) in day6 group. In day5 group, the false-negative rate was 10.5% (10/95), and false-positive rate was 16.8% (16/95) while in day6 group the false-negative rate was 6,8% (10/145), and false-positive rate was 8,2% (12/145). Sensitivity and specificity were calculated as 83,6% and 52,9% in day5 group, and 90,9% and 65,7 in day6 group respectively
Limitations, reasons for caution
We have high number of samples in our study, but larger prospective studies may change the significance of ploidy concordance. One of the important issues in SCM analysis is the maternal DNA contamination risk which cannot be revealed always. Therefore the use of molecular markers would increase the reliability
Wider implications of the findings
A non-invasive approach for aneuploidy screening may be an alternative to standard PGT-A procedure with invasive embryo biopsy but the evaluation of ideal culture time is crucial for the performance of niPGT-A method. Our study demonstrates that the late collection time of SCM provides significantly better ploidy concordance rates

Abstract
A dural arteriovenous fistula (DAVF) is an abnormal direct connection between an intracranial artery and the dural venous sinus. In rare cases, DAVF might show rapidly progressive dementia onset with extrapyramidal signs, often misdiagnosed as Parkinson disease or vascular parkinsonism and, therefore, pharmacological treatments are ineffective. Here, we report the case of 84-year-old man with rapidly progressive parkinsonism and dementia who was initially treated with levodopa without any improvement. Approximately 8 months following the symptom onset, a magnetic resonance (MR) imaging of the brain revealed bilateral and symmetrical hyperintensity of the white matter on both cerebral hemispheres on T2-weighted images. Three-dimensional and post-contrast T1-weighted images showed a subtentorial ovalar area with venous drainage alteration, and hypertrophic left occipital artery direct to venous sac. The angiography study confirmed a diagnosis of DAVF. Endovascular treatment by cook pressure technique successfully provided fistula obliteration. The patient rapidly recovered after the endovascular treatment, with restitutio ad integrum of cognitive functioning and resolution of extrapyramidal syndrome. Approximately 1 year after the endovascular treatment, a brain MR scan with angiogram-MR sequences showed almost complete disappearance of white matter alterations on both cerebral hemispheres, and normal visualization of venous system.

Abstract
Abstract
Study question
To explore ploidy concordance between invasive and non-invasive PGTA (niPGT-A) at different embryo culture time.
Summary answer
High level (>84%) of concordance rate for ploidy and sex, sensitivity (>88%), and specificity (76%) were obtained for both day6/7 samples and day5 samples.
What is known already
The analysis of embryo cell free DNA (cfDNA) that are released into culture media during in vitro embryo development has the potential to evaluate embryo ploidy status. However, obtaining sufficient quality and quantity of cfDNA is essential to achieve interpretable results for niPGT-A. More culture time is expected to be directly proportional to the release of more cfDNA. But embryo culture time is limited due to in-vitro embryo survival potential. Therefore, it is important to estimate the duration of the culture that will provide the maximum cfDNA that can be obtained without adversely affecting the development of the embryo.
Study design, size, duration
A total of 105 spent culture media (SCM) from day5-day7 blastocyst stage embryos have been included in this cohort study. The cfDNA of SCM samples were amplified and analyzed for niPGT-A by NGS analysis. The SCM samples were divided into 2 subgroups according the embryo culture hours (Day5 and Day6/7 group). The DNA concentration, informativity and euploidy results have then been compared with their corresponding embryos after trophectoderm biopsy (TE) and PGT-A analysis by NGS
Participants/materials, setting, methods
Embryos cultured until Day3 washed and cultured again in 20µl fresh culture media until embryo biopsy on Day5, 6, or 7. After biopsy SCM samples were immediately collected in PCR tubes and conserved at –20 °C until whole genome amplification by MALBAC® (Yicon Genomics). The TE and SCM samples were analyzed by next-generation sequencing (NGS) using Illumina MiSeq® System. NGS data analysis has been done by Bluefuse Multi Software 4.5 (Illumina) for SCM and TE samples
Main results and the role of chance
Only the SCM samples which have an embryo with a conclusive result were included in this cohort (n = 105). Overall 97.1% (102/105) of SCM samples gave a successful DNA amplification with a concentration ranging 32.4–128.5ng/µl. Non-informative (NI) results including a chaotic profile (>5 chromosome aneuploidies) were observed in 17 samples, so 83.3%(85/102) of SCM samples were informative for NGS data analysis. Ploidy concordance rate with the corresponding TE biopsies (euploid vs euploid, aneuploid vs aneuploid) was 84.7% (72/85). Sensitivity and specificity were 92,8% and 76,7%, respectively with no significant difference for all parameters for day 6/7 samples compared with day 5 samples. The false-negative rate was 3.5% (3/85), and false-positive rate was 11.7% (10/85).
Limitations, reasons for caution
The sample size is relatively small. Larger prospective studies are needed. As this is a single-center study, the impact of the variations in embryo culture conditions can be underestimated. Maternal DNA contamination risk cannot be revealed in SCM, therefore the use of molecular markers would increase the reliability.
Wider implications of the findings: Non-invasive analysis of embryo cfDNA analyzed in spent culture media demonstrates high concordance with TE biopsy results in both early and late culture time. A non-invasive approach for aneuploidy screening offers important advantages such as avoiding invasive embryo biopsy and decreased cost, potentially increasing accessibility for a wider patient population.

Abstract
BACKGROUND AND PURPOSE The aspiration technique has gained a prominent role in mechanical thrombectomy. The thrombectomy goal is successful revascularization (modified TICI ≥ 2b) and first-pass effect. The purpose of this study was to evaluate the impact of the vessel-catheter ratio on the modified TICI ≥ 2b and first-pass effect. MATERIALS AND METHODS This was a retrospective, single-center, cohort study. From January 2018 to April 2020, 111/206 (53.9%) were eligible after applying the exclusion criteria. Culprit vessel diameters were measured by 2 neuroradiologists, and the intraclass correlation coefficient was calculated. The receiver operating characteristic curve was used for assessing the vessel-catheter ratio cutoff for modified TICI ≥ 2b and the first-pass effect. Time to groin puncture and fibrinolysis were weighted using logistic regression. All possible intervals (interval size, 0.1; sliding interval, 0.01) of the vessel-catheter ratio were plotted, and the best and worst intervals were compared using the χ2 test. RESULTS Modified TICI ≥ 2b outcome was achieved in 75/111 (67.5%), and first-pass effect was achieved in 53/75 (70.6%). The MCA diameter was 2.1 mm with an intraclass correlation coefficient of 0.92. The optimal vessel-catheter ratio cutoffs for modified TICI ≥ 2b were ≤1.51 (accuracy = 0.67; 95% CI, 0.58-0.76; P = 0.001), and for first-pass effect, they were significant (≤1.33; P = .31). The modified TICI ≥ 2b odds ratio and relative risk were 9.2 (95% CI, 2.4-36.2; P = 0.002) and 3.2 (95% CI, 1.2-8.7; P = .024). The odds ratio remained significant after logistic regression (7.4; 95% CI, 1.7-32.5; P = .008). First-pass effect odds ratio and relative risk were not significant (2.1 and 1.5; P > .05, respectively). The modified TICI ≥ 2b best and worst vessel-catheter ratio intervals were not significantly different (55.6% versus 85.7%, P = .12). The first-pass effect best vessel-catheter ratio interval was significantly higher compared with the worst one (78.6% versus 40.0%, P = .03). CONCLUSIONS The aspiration catheter should be selected according to culprit vessel diameter. The optimal vessel-catheter ratio cutoffs were ≤1.51 for modified TICI ≥ 2b with an odds ratio of 9.2 and a relative risk of 3.2.

Abstract
Background and Purpose—
As a reliable scoring system to detect the risk of symptomatic intracerebral hemorrhage after thrombectomy for ischemic stroke is not yet available, we developed a nomogram for predicting symptomatic intracerebral hemorrhage in patients with large vessel occlusion in the anterior circulation who received bridging of thrombectomy with intravenous thrombolysis (training set), and to validate the model by using a cohort of patients treated with direct thrombectomy (test set).
Methods—
We conducted a cohort study on prospectively collected data from 3714 patients enrolled in the IER (Italian Registry of Endovascular Stroke Treatment in Acute Stroke). Symptomatic intracerebral hemorrhage was defined as any type of intracerebral hemorrhage with increase of ≥4 National Institutes of Health Stroke Scale score points from baseline ≤24 hours or death. Based on multivariate logistic models, the nomogram was generated. We assessed the discriminative performance by using the area under the receiver operating characteristic curve.
Results—
National Institutes of Health Stroke Scale score, onset-to-end procedure time, age, unsuccessful recanalization, and Careggi collateral score composed the IER-SICH nomogram. After removing Careggi collateral score from the first model, a second model including Alberta Stroke Program Early CT Score was developed. The area under the receiver operating characteristic curve of the IER-SICH nomogram was 0.778 in the training set (n=492) and 0.709 in the test set (n=399). The area under the receiver operating characteristic curve of the second model was 0.733 in the training set (n=988) and 0.685 in the test set (n=779).
Conclusions—
The IER-SICH nomogram is the first model developed and validated for predicting symptomatic intracerebral hemorrhage after thrombectomy. It may provide indications on early identification of patients for more or less postprocedural intensive management.

Abstract
Thirteen cases of cerebral aneurysms submitted to endovascular treatment using Guglielmi detachable coils (GDC) are described. Control MRI-angiography 3D TOF was performed three and six months later. In order to spare patients the discomfort and risks related to repeated trauma and iodate contrast injection, we examined the possibility of an alternative non-invasive diagnostic method. For this purpose, the digital subtraction angiograms performed three and six months after embolisation were compared with the MR-angiograms obtained in the same period, all using the same tomograph at middle field intensity (0.5T). We discuss the outcome of this comparison and the limits of the MR-angiography method in the follow-up of aneurysms submitted to endovascular treatment.

Abstract
The acquired pellicle adheres to tooth surfaces and has been suggested to provide differing degrees of protection against acidic erosion. This study investigated whether pellicle formed on enamel blocks in patients suffering dietary dental erosion modified the effect of an in vitro simulated dietary challenge, in comparison with pellicle formed on enamel blocks in healthy subjects and to no-pellicle enamel samples. Sixty subjects recruited from dental erosion clinics were compared to healthy age-matched controls. Subjects wore a custom-made maxillary splint holding human enamel blocks for 1 h during which the acquired enamel pellicle was formed. Enamel blocks were removed from the splints and a simulated dietary erosive challenge of 10 min was performed. In addition the challenge was performed on 30 enamel samples without pellicle. Profilometry showed no statistical difference between samples from the erosion subjects with a mean step height of 1.74 µm (SD 0.88) and median roughness (Sa) of 0.39 µm (interquartile range, IQR 0.3-0.56) and the controls with 1.34 µm (SD 0.66) and 0.33 µm (IQR 0.27-0.38), respectively. The control samples without pellicle had Sa of 0.44 µm (IQR 0.36-0.69) and these differences were statistically significant compared to those from the healthy subjects (p = 0.002). Mean (SD) microhardness reduction with a 100-gram load for the erosion group was 113.5 (10) KHN, for healthy subjects was 93 (15.4) KHN and for the enamel samples without pellicle 139.6 (21.8) KHN and all groups were statistically different. The microhardness and roughness data suggested the pellicle influenced erosion under these study conditions.

Abstract
Abstract
BACKGROUND
Giant perimedullary arteriovenous fistulas (GPMAVFs) located in the cervical region are a rare pathology with distinctive characteristics.
OBJECTIVE
To evaluate clinical presentation and different endovascular treatment options of cervical GPMAVFs and review previously published data in the literature regarding cervical GPMAVFs.
METHODS
Six patients with cervical GPMAVFs were found in the spinal vascular malformations database of our group collected between 1990 and 2009. Endovascular techniques and treatment outcomes were evaluated and compared with other published series.
RESULTS
Clinical presentations were progressive motor deficit (5 patients), hematomyelia (1 patient), meningeal syndrome (1 patient), and respiratory arrest and gait apraxia (1 patient). Three patients were treated by the transarterial approach. One patient was treated by the transvenous approach due to previous embolizations resulting in a proximal occlusion and preventing a safe transarterial approach. A transvenous approach was used in another patient due to complex arterial anatomy. In 1 patient, direct percutaneous puncture of the venous pouch was necessary because of previous proximal occlusion of the arteries. All embolizations resulted in complete occlusions with clinical improvement, and there was no recanalization during a mean follow-up of 21 months.
CONCLUSION
Transarterial embolization of cervical GPMAVFs is safe and effective when it is done in highly experienced centers. Cervical GPMAVFs that cannot be accessed by the transarterial technique due to their complex angioarchitecture can be treated by transvenous embolization or direct puncture of the venous pouch.

Abstract
OBJECT A series of 306 consecutive patients with an anterior communicating artery (ACoA) aneurysm is presented. The goal in this study was to report the results of endovascular treatment of ACoA aneurysms in these patients. METHODS The aneurysms were managed with an endovascular approach in which detachable coils were used. A brief anatomical description of the ACoA and its branches as well as a review of the surgical and endovascular literature is presented. The "ACoA Syndrome" (that is, amnesia and personality changes), which may occur after subarachnoid hemorrhage, is briefly reviewed and described. Recent technical developments that can lead to improved results are also discussed. RESULTS Of the 306 aneurysms, 268 (87.5%) were small, 30 (10%) were large, and 8 (2.6%) were giant. One hundred ninety-three aneurysms (63%) had a small neck, whereas 113 (37%) had a wide neck. Sixty-five lesions (21%) were incidental, 5 (2%) presented with symptoms of mass effect, and 236 (77%) presented with a subarachnoid hemorrhage. A complete aneurysm occlusion was attained in 139 cases (45.5%), a neck remnant was detected in 145 (47.5%), and in 22 cases (7%) a residual filling of the aneurysm was observed. Regarding the clinical neurological outcome, 280 patients (91.5%) remained neurologically intact, improved, or unchanged from their initial clinical status. Two large, wide-necked, subtotally occluded aneurysms ruptured 3-7 months after the procedure, with subsequent death of the patients. The procedure-related morbidity and mortality rates were 3.5% (11 cases) and 1% (3 cases), respectively. CONCLUSIONS The inherently lower risk of injuring or occluding the delicate branches and perforating vessels arising from the ACoA makes the endovascular approach attractive, interesting, and elegant.

Abstract
SUMMARY The endovascular approach is described in 113 middle cerebral artery (MCA) aneurysms. The treatment failed in six cases with no adverse clinical consequences. Out of the 107 treated cases, it was possible to obtain a complete occlusion in 50 aneurysms (47%), whereas a residual aneurysm neck was observed in 54 cases (50%). Follow-up angiograms were performed in 60 cases, showing a 22% rate of further thrombosis of the aneurysm. Recanalization of the aneurysm was observed in 8% of cases, which required retreatment. The technique-related permanent morbidity rate was 9% while the mortality rate was 2%. A review of the surgical and endovascular literature is presented. The endovascular approach is particularly indicated when normal MCA branches do not arise from the aneurysm base. It must be meticulously planned in all other cases. Endovascular coil treatment of MCA aneurysms is feasible, with acceptable morbi-mortality rates.

Abstract
SUMMARY Four cases of posterior cerebral artery (PCA) aneurysms are described. The aneurysms were located at the P2 segment of PCA. All cases presented with a subarachnoid hemorrhage (SAH). Endovascular treatment was performed, with occlusion of the aneurysm and parent vessel, using platinum coils. Two patients developed a homonymus lateral hemianopia after treatment.

Abstract
The following study aims to establish the role of MRI in investigation of the CNS in children. 300 patients are examined, 220 affected by CNS disease. The examinations were performed using SE sequence (T1-weighted images TR = 350-700 ms TE = 30-60 ms; T2-weighted images TR = 1500-2000 ms TE = 50-200 ms). In most of the patients general anesthesia or sedation was necessary. Patients are divided into groups based on pathology and the advantages and shortcomings of MRI are discussed. In conclusion, MRI should be the technique of choice in the evaluation of malformative affections, white matter and inflammatory disease; it should be complementary to CT and angiography in tumors and vascular pathology.

Abstract
Fifty-two patients were studied with high-field magnetic resonance imaging (1.5T), with T1- and T2-weighted spin-echo pulse sequences. The study was aimed at assessing the efficacy of MR imaging in the evaluation of intracranial hematomas. Characteristic intensity patterns were observed in the evolution of the hematomas, due to the physicochemical changes in hemoglobin. No acute hematomas were observed. In 35 sub-acute hematomas, peripheral hyperintensity could be observed on T1- and T2-weighted pulse sequences. This hyperintensity eventually fills in the hematoma in the chronic stage. In 17 chronic hematomas, a peripheral hypointense ring due to hemosiderin deposits was seen on T1- and T2-weighted scans. The authors conclude that high-field MR imaging is a very sensible diagnostic method in the evaluation of sub-acute and chronic hematomas.

Abstract
The authors report a new case of Joubert syndrome (agenesis of the cerebellar vermis, mental retardation, disturbance of respiratory rhythm, ataxia, abnormal eye-movements) and review the relevant literature on the other nine cases reported. The diagnosis in the present case was confirmed by computerized tomography. Early recognition of this syndrome is important in view of the prognosis and for genetic counseling.
