Aim: Migraine is neurological disorder with a complex pathophysiology. We described the neuropsychological profile of 100 migraineurs (50 with visual aura and 50 without aura), in interictal phase, compared to 50 matched healthy controls.
Materials and methods: A battery of standardized neuropsychological tests was used to assess attention, memory and executive functions. Beck Depression Inventory and Hamilton Rating Scale for Anxiety were used to evaluate anxiety and depressive symptoms. Severity of disability during daily activities was assessed by Migraine Disability Assessment.
Results: Migraine without aura showed a significant difference in comparison to healthy controls in semantic verbal fluency (p?=?0.02), delayed memory (p?<?0.001) and set-shifting (p?<?0.001). Migraine with aura showed a significant difference in delayed memory (p?=?0.001) and set-shifting (p?=?0.005) if compared to healthy controls. No significant correlation between cognitive functions and mood was found (HAM-A p?=?0.67) (BDI-II p?=?0.42).
Conclusions: Our data showed isolate and specific cognitive deficit during interictal phase in migraine patients. Future studies are need to identify if specific migraine characteristics may affect cognitive functions. 相似文献
Partial nephrectomy (PN) is standard for small renal masses, improving renal function by preserving renal parenchyma compared with radical nephrectomy. Recent work demonstrated that postoperative surgeon assessment of volume preservation (SAVP) and 3D imaging measurements agree and correlate with postoperative function. We hypothesize preoperative assessment of volume preservation (PAVP) with PN based on preoperative imaging will reliably indicate postoperative renal function.
Materials and Methods
Data were collected from 336 patients undergoing PN for suspected renal cancer by 40 surgeons at 12 centers in Europe and the United States within the Surface-Intermediate-Base International Consortium. Surgeons recorded PAVP and SAVP for individual patients; pre- and postoperative glomerular filtration rate (GFR) was estimated by Chronic Kidney Disease Epidemiology Collaboration equations. Correlations between PAVP, SAVP, and postoperative GFR were assessed with linear regression models. Bland–Altman analysis was used to assess agreement between PAVP and SAVP with a significant cutoff of 5%.
Results
Median PAVP was 90% (interquartile range [IQR] 85%–100%) and SAVP was 90% (IQR: 80%–94%). PAVP and SAVP were moderately correlated (R2?=?0.67, P < 0.0001) and deemed “interchangeable” by Bland–Altman analysis at a 5% acceptable rate of difference (95% CI: ?5.4, ?3.1). Median postoperative GFR was 77.3 (IQR: 56.2, 92.0). Both PAVP (R2?=?0.82, P < 0.0001) and SAVP (R2?=?0.83, P < 0.0001) were correlated with postoperative GFR. Multivariable models utilizing volume-adjusted GFR based on PAVP or SAVP significantly and similarly predicted postoperative GFR (R2?=?0.72 for each).
Conclusion
Renal function is closely linked to the amount of parenchymal volume preservation, whether estimated prior to surgery (PAVP) or afterward (SAVP). PAVP provides reasonably accurate information for decision-making in patients considering PN. 相似文献
Treatment guidelines recommend the routine use of point-of-care diagnostic tests for coagulopathy in the management of cardiac surgery patients at risk of severe bleeding despite uncertainty as to their diagnostic accuracy. We performed a systematic review and meta-analysis of studies that evaluated the diagnostic accuracy of viscoelastometry, platelet function tests, and modified thromboelastography (TEG) tests, for coagulopathy in cardiac surgery patients. The reference standard included resternotomy for bleeding, transfusion of non-red cell components, or massive transfusion. We searched MEDLINE, EMBASE, CINAHL, and Clinical Trials.gov, from inception to June 2019. Study quality was assessed using QUADAS-2. Bivariate models were used to estimate summary sensitivity and specificity with (95% confidence intervals). All 29 studies (7440 participants) included in the data synthesis evaluated the tests as predictors of bleeding. No study evaluated their role in the management of bleeding. None was at low risk of bias. Four were judged as low concern regarding applicability. Pooled estimates of diagnostic accuracy were; Viscoelastic tests, 12 studies, sensitivity 0.61 (0.44, 0.76), specificity 0.83 (0.70, 0.91) with significant heterogeneity. Platelet function tests, 12 studies, sensitivity 0.63 (0.53, 0.72), specificity 0.75 (0.64, 0.84) with significant heterogeneity. TEG modification tests, 3 studies, sensitivity 0.80 (0.67, 0.89), specificity 0.76 (0.69, 0.82) with no evidence of heterogeneity. Studies reporting the highest values for sensitivity and specificity had important methodological limitations. In conclusion, we did not demonstrate predictive accuracy for commonly used point-of-care devices for coagulopathic bleeding in cardiac surgery. However, the certainty of the evidence was low. 相似文献
Recent trials established the efficacy of mechanical stent-retriever thrombectomy for treatment of stroke patients with large vessel occlusion (LVO) in the anterior circulation. However, stent-retriever thrombectomy may not accomplish successful recanalization in all patients. The aim of this study is to report the role of bail-out permanent stenting after failure of mechanical thrombectomy.
Methods
Among 430 patients included in a prospectively maintained database, we analysed 325 cases of anterior circulation LVO. Mechanical thrombectomy (mTICI 2b-3) was effective in 213/325 (65%) and failed in 112/325 (35%). Bail-out intracranial stenting was performed in 17/325 (5.2%) patients. In all cases a fully retrievable detachable stent was used (Solitaire AB, Medtronic).
Results
No intraprocedural technical complications occurred. Successful reperfusion (mTICI 2b/3) was achieved in 12/17 patients (70.6%). Three (17.6%) patients died: one extensive infarction in the internal carotid artery territory, one large intracerebral haemorrhage, and one massive pulmonary embolism. Haemorrhagic conversion, both symptomatic and asymptomatic, occurred in 2/17 (11.7%). Good clinical outcome (mRS 0–2) at 3-months was achieved in 41.2% of patients.
Conclusion
Bail-out intracranial stenting after unsuccessful thrombectomy is technically feasible and the associated haemorrhagic risk seems acceptable in selected patients. We suggest that bail-out intracranial stenting, is safe and effective in selected patients with LVO stroke who failed to respond to thrombectomy. 相似文献
Background and aimsBeyond type 2 diabetes, even a condition of prediabetes is associated with an increased cardiovascular (CV) risk, and HCV infection coexistence represents an exacerbating factor. CV prognosis improvement in prediabetes represents a challenge, due to the increasing prevalence of this metabolic condition worldwide. Hence, we aimed to prospectively assess how direct acting antivirals (DAAs) could affect major cardiovascular events (MACE) in a prediabetic HCV positive cohort.Methods and resultsIn this prospective multicenter study, we enrolled HCV patients with overt prediabetes. We compared a subgroup of patients treated with DAAs with untreated prediabetic controls. We recorded all CV events occurred during an overall median follow-up of 24 months (IQR 19–34). 770 HCV positive prediabetic patients were enrolled, 398 untreated controls and 372 DAAs treated patients. Overall, the CV events annual incidence was much higher among prediabetic treated patients (1.77 vs. 0.62, p < 0.001), and HCV clearance demonstrated to significantly reduce CV events (RR: 0.411, 95%CI 0.148–1.143; p < 0.001), with an estimated NNT for one additional patient to benefit of 52.1. Moreover, an independent association between a lower rate of CV events and HCV clearance after DAAs was observed (OR 4.67; 95%CI 0.44–53.95; p = 0.016).ConclusionsHCV eradication by DAAs allows a significant reduction of MACEs in the prediabetic population, and therefore represents a primary objective, regardless of the severity of liver disease and CV risk factors. 相似文献
