OBJECTIVECerebral hyperperfusion syndrome (CHS) is a rare but devastating complication of carotid endarterectomy (CEA). This study sought to determine whether quantitative hemodynamic assessment using MR angiography can stratify CHS risk.METHODSIn this prospective trial, patients with internal carotid artery (ICA) stenosis were randomly selected for pre- and postoperative quantitative phase-contrast MR angiography (QMRA). Assessment was standardized according to a protocol and included Doppler/duplex sonography, MRI, and/or CT angiography and QMRA of the intra- and extracranial supplying arteries of the brain. Clinical and radiological data were analyzed to identify CHS risk factors.RESULTSTwenty-five of 153 patients who underwent CEA for ICA stenosis were randomly selected for pre- and postoperative QMRA. QMRA data showed a 2.2-fold postoperative increase in blood flow in the operated ICA (p < 0.001) and a 1.3-fold increase in the ipsilateral middle cerebral artery (MCA) (p = 0.01). Four patients had clinically manifested CHS. The mean flow increases in the patients with CHS were significantly higher than in the patients without CHS, both in the ICA and MCA (p < 0.001). Female sex and a low preoperative diastolic blood pressure were the clearest clinical risk factors for CHS, whereas the flow differences and absolute postoperative flow values in the ipsilateral ICA and MCA were identified as potential radiological predictors for CHS.CONCLUSIONSCerebral blood flow in the ipsilateral ICA and MCA as assessed by QMRA significantly increased after CEA. Higher mean flow differences in ICA and MCA were associated with the development of CHS. QMRA might have the potential to become a noninvasive, operator-independent screening tool for identifying patients at risk for CHS.

OBJECTIVEEndovascular thrombectomy in patients with acute ischemic stroke caused by occlusion of the proximal anterior circulation arteries is superior to standard medical therapy. Stentriever thrombectomy with or without aspiration assistance was the predominant technique used in the 5 randomized controlled trials that demonstrated the superiority of endovascular thrombectomy. Other studies have highlighted the efficacy of a direct aspiration first-pass technique (ADAPT).METHODSTo compare the angiographic and clinical outcomes of ADAPT versus stentriever thrombectomy in patients with emergent large vessel occlusions (ELVO) of the anterior intracranial circulation, the records of 134 patients who were treated between June 2012 and October 2015 were reviewed.RESULTSWithin this cohort, 117 patients were eligible for evaluation. ADAPT was used in 47 patients, 20 (42.5%) of whom required rescue stentriever thrombectomy, and primary stentriever thrombectomy was performed in 70 patients. Patients in the ADAPT group were slightly younger than those in the stentriever group (63.5 vs 69.4 years; p = 0.04); however, there were no differences in the other baseline clinical or radiographic factors. Procedural time (54.0 vs 77.1 minutes; p < 0.01) and time to a Thrombolysis in Cerebral Infarction (TICI) scale score of 2b/3 recanalization (294.3 vs 346.7 minutes; p < 0.01) were significantly lower in patients undergoing ADAPT versus stentriever thrombectomy. The rates of TICI 2b/3 recanalization were similar between the ADAPT and stentriever groups (82.9% vs 71.4%; p = 0.19). There were no differences in the rates of symptomatic intracranial hemorrhage or procedural complications. The rates of good functional outcome (modified Rankin Scale Score 0–2) at 90 days were similar between the ADAPT and stentriever groups (48.9% vs 41.4%; p = 0.45), even when accounting for the subset of patients in the ADAPT group who required rescue stentriever thrombectomy.CONCLUSIONSThe present study demonstrates that ADAPT and primary stentriever thrombectomy for acute ischemic stroke due to ELVO are equivalent with respect to the rates of TICI 2b/3 recanalization and 90-day mRS scores. Given the reduced procedural time and time to TICI 2b/3 recanalization with similar functional outcomes, an initial attempt at recanalization with ADAPT may be warranted prior to stentriever thrombectomy.

OBJECTIVEIn this paper, the authors set out to identify the angiographic features of moyamoya disease with posterior hemorrhage, which is a strong predictor of rebleeding.METHODSThis cross-sectional study used the data set of the Japan Adult Moyamoya Trial (clinical trial registration no.: C000000166 [www.umin.ac.jp/ctr/index.htm]). The panel designed the ancillary measurement of angiography at onset, classifying the collateral vessels into 3 subtypes: lenticulostriate anastomosis, thalamic anastomosis, and choroidal anastomosis. The association between each collateral and the hemorrhage site (anterior vs posterior) was assessed in the hemorrhagic hemisphere by using multivariate adjustment for potential confounders, including age, sex, and involvement of the posterior cerebral artery (PCA). The association was confirmed through topographical analysis of bleeding points.RESULTSAmong the 80 participants, 75 hemorrhagic hemispheres of 75 patients were analyzed. Lenticulostriate anastomosis was detected in 21 (28.0%) hemorrhagic hemispheres, thalamic anastomosis in 22 (29.3%), and choroidal anastomosis in 35 (46.7%). Choroidal anastomosis was a factor associated with posterior hemorrhage (OR 2.77 [95% CI 1.08–7.10], p = 0.034) and remained statistically significant after the multivariate adjustment (OR 2.66 [95% CI 1.00–7.07], p = 0.049). PCA involvement was also associated with posterior hemorrhage in both univariate and multivariate analyses. Topographical analysis revealed good correspondence between bleeding points associated with positive choroidal anastomosis and the anatomical distribution of the choroidal arteries, including the thalamus and the wall of the atrium.CONCLUSIONSChoroidal anastomosis and PCA involvement are characteristic of posterior hemorrhage in moyamoya disease. Choroidal anastomosis might be considered a potential source of posterior hemorrhage at high risk of rebleeding.

OBJECTIVEDecompressive craniectomy (DC) is an established part of treatment in patients suffering from malignant infarction of the middle cerebral artery (MCA) or traumatic brain injury (TBI). However, no clear evidence for intracranial pressure (ICP)-guided therapy after DC exists. The lack of this evidence might be due to the frequently used, but simplified threshold for ICP of 20 mm Hg, which determines further therapy. Therefore, the objective of this study was to evaluate this threshold's accuracy and to investigate the course of ICP values with respect to neurological outcome.METHODSData on clinical characteristics and parameters of the ICP course on the intensive care unit were collected retrospectively in 102 patients who underwent DC between December 2007 and April 2014 at the authors' institution. The postoperative ICP course in the first 168 hours was recorded and analyzed. From these findings, ICP thresholds discriminating favorable from unfavorable outcome were calculated using conditional inference tree analysis. Additionally, survival analysis was performed using the Kaplan-Meier method. Prognostic factors were assessed via univariate analysis and multivariate logistic regression. Favorable outcome was defined as a score of 0–4 on the modified Rankin Scale.RESULTSMultivariate logistic regression revealed that anisocoria, diagnosis, and ICP values differed significantly between the outcome groups. ICP values in the favorable and unfavorable outcome groups differed significantly (p < 0.001), while the mean ICP of both groups lay below the limit of 20 mm Hg (17.5 and 11.5 mm Hg, respectively). These findings were reproduced when analyzing the underlying pathologies of TBI and MCA infarction separately. Based on these findings, optimized time-dependent threshold values were calculated and found to be between 10 and 17 mm Hg. These values significantly distinguished favorable from unfavorable outcome and predicted 30-day mortality (p < 0.001).CONCLUSIONSThis study systematically evaluated ICP levels in a long-term analysis after DC and provides new, surprisingly low, time-dependent ICP thresholds for these patients. Future trials investigating the benefit of ICP-guided therapy should take these thresholds into consideration and validate them in further patient cohorts.

OBJECTIVEEndoscopic strip craniectomy (ESC) with postoperative helmet orthosis is a well-established treatment option for sagittal craniosynostosis. There are many technical variations to the surgery ranging from simple strip craniectomy to methods that employ multiple cranial osteotomies. The purpose of this study was to determine whether the addition of lateral barrel-stave osteotomies during ESC improved morphological outcomes.METHODSAn IRB-approved retrospective review was conducted on a consecutive series of cases involving ESC for sagittal craniosynostosis at 2 different institutions from March 2008 to August 2014. The patients in Group A underwent ESC and those in Group B had ESC with lateral barrel-stave osteotomies. Demographic and perioperative data were recorded; postoperative morphological outcomes were analyzed using 3D laser scan data acquired from a single orthotic manufacturer who managed patients from both institutions.RESULTSA total of 73 patients were included (34 in Group A and 39 in Group B). Compared with Group B patients, Group A patients had a shorter mean anesthetic time (161.7 vs 195 minutes; p < 0.01) and operative time (71.6 vs 111 minutes; p < 0.01). The mean hospital stay was similar for the 2 groups (1.2 days for Group A vs 1.4 days for Group B; p = 0.1). Adequate postoperative data on morphological outcomes were reported by the orthotic manufacturer for 65 patients (29 in Group A and 36 in Group B). The 2 groups had similar improvement in the cephalic index (CI): Group A, mean change 10.5% (mean preoperative CI 72.6, final 80.4) at a mean follow-up of 13.2 months; Group B, mean change 12.2% (mean preoperative CI 71.0, final 79.6) at a mean follow-up of 19.4 months. The difference was not statistically significant (p = 0.15).CONCLUSIONSBoth ESC alone and ESC with barrel staving produced excellent outcomes. However, the addition of barrel staves did not improve the results and, therefore, may not be warranted in the endoscopic treatment of sagittal craniosynostosis.

Background: Recent genetic and epidemiological studies have shown that there is a link between essential tremor and Parkinson’s disease (PD). However, there is a lack of data about the clinical features of PD developed from essential tremor. Objective: To explore and describe the clinical characteristics of Parkinson’s disease developed from essential tremor (ET-PD). Methods: Twenty-five ET-PD patients and 124 IPD controls were enrolled according to each criterion. Motor and non-motor features and dopamine transporter uptake were compared between the two groups. Results: Rest and action tremors were more severe in ET-PD patients than in IPD patients. In addition, tremor disorder of first-degree relatives occurred more frequently in the ET-PD group than in the IPD group. A comparison between cases with ET-PD and IPD was not significant for striatal dopamine transporter uptake. Among the non-motor features, sleep disorder frequency, especially rapid-eye-movement sleep behavioral disorder, were lower in patients with ET-PD than in those with IPD, and smell identification test scores were higher in patients with ET-PD than in those with IPD. The prevalence of other non-motor symptoms did not differ between the two groups. Conclusion: This is the first comparison of motor and non-motor features between ET-PD and IPD. ET-PD and IPD have different characteristic motor and non-motor features from the nosologic perspective.

Published: April 2017

Vegetable oil rich in omega-3 and omega-6 fatty acids is an important element in the diet of most transitional countries. The ratio of omega-6 to omega-3 in modern diets is approximately 15:1, whereas ratios of 2:1 to 4:1 have been associated with reduced mortality from cardiovascular disease, suppressed inflammation in patients with rheumatoid arthritis, and decreased risk of breast cancer. The study was designed to investigate the fatty acid profile of six types of seed oils such as peanut, linseed, olive, soybean, sesame and sunflower oil. Afterwards the author prepared mixed vegetable oils with effective Omega-6 (n-6)/omega-3 (n-3) fatty acid ratio. It was found that the highest percentage (39.9%) of saturated fatty acid found in Linseed oil and the highest percentage (37.1%) of monounsaturated fatty acid found in Sesame oil. It was also observed that olive and soybean oil contain 100% polyunsaturated fatty acid and the lowest percentages (35.2%) of polyunsaturated fatty acid were found in Sesame oil. After preparing a mixed vegetable oil The ratio of n-6 to n-3 were 3.5:1 (soybean), 19:1 (olive), 0.43:1 (linseed), 0.13:1 (peanut) and sesame (16.5:1). It is also noted that n-3 was not detected in sunflower oil. Thus the investigation showed that Soybean oil contains the balanced omega-6/omega-3 fatty acid ratio than others.J. Environ.

Background The optimal time for the commencement of peritoneal dialysis (PD) after PD catheter insertion is unclear. If dialysis is started too soon after insertion, dialysate leaks and infection could occur. However, by starting PD earlier, morbidity and costs can be reduced through lesser hemodialysis requirements. This is the first randomized controlled trial to determine the safest and shortest interval to commence PD after catheter insertion. Methods All consecutive patients undergoing PD catheter insertion at the Royal Brisbane and Women's Hospital and Rockhampton Hospital from 1 March 2008 to 31 May 2013 who met the inclusion and exclusion criteria were invited to participate in the trial. Participants were randomized to 1 of 3 groups. Group 1 (G1) commenced PD at 1 week, group 2 (G2) at 2 weeks and group 3 (G3) at 4 weeks after PD catheter insertion. These groups were stratified by hospital and the presence of diabetes. Primary outcomes were the incidence of peritoneal fluid leaks or PD-related infection during the 4 weeks after commencement of PD. Results In total 122 participants were recruited, 39, 42, and 41 randomized to G1, G2, and G3, respectively. The primary outcome catheter leak was significantly higher in G1 (28.2%) compared with G3 (2.4%, p = 0.001) but not compared with G2 (9.5%, p = 0.044), based on intention to treat analysis. These differences were even more marked when analyzed with per protocol method: G1 had a significantly higher percentage (32.4 %) compared with G3 (3.3%, p = 0.003) but not compared with G2 (10.5%, p = 0.040). Event percentages of leak were statistically higher in G1 and occurred significantly earlier compared with other groups ( p = 0.002). Amongst diabetics, technique failure was significantly higher (28.6%) in G3 compared with 0% in G1 and 7.1% in G2 ( p = 0.036) and earlier in G3 at 163.2 days vs 176.8 and 175.8 ( p = 0.037) for G1 and G2, respectively. Conclusion Leaks were higher in participants commencing PD at 1 week after catheter insertion compared with the other 2 groups, and technique failure was higher in diabetics starting PD at 4 weeks.

Background Peritoneal dialysis (PD) catheter surgery can be performed using regional anesthesia. We present our PD catheter placement and extraction experience using ultrasound-guided transversus abdominis plane (TAP) block. Methods In the present study, we analyzed 74 patients from our center with end-stage renal disease (ESRD) who underwent PD catheter placement (60 patients) and removal (14 patients) using a TAP block between June 2011 and December 2015. Results The TAP block was successful for 55/60 (91.7%) patients (insertion) and 13/14 (92.9%) patients (extraction). Other patients had pain at the incision site and required general anesthesia. There were no anesthesia-, surgery- or PD catheter-related complications. Conclusion The TAP block is a safe and effective technique not only for high-risk ESRD patients but for all patients undergoing PD catheter placement or extraction.

Objective: Describe the conceptions of resident nurses about the nurse's role in mental health services.
Method: Descriptive/reflexive study of the experience-report type, carried out from experiences of nurses from the Multiprofessional Residency Program in Mental Health, guided by the theoretical presuppositions of the Brazilian Psychiatric Reform and structured from the Arch of Charles Maguerez.
Results: In-service teaching provided reflections on the residents' conceptions of nurses' performance in mental health services. The key posts were the insertion in the specific nursing care, the construction of the multiprofessional work process, the recognition of their professional identity. Therapeutic relationship and communication, receptiveness, co-responsibility of care and the construction of links with clients, family and work colleagues for the solution of the problems.
Conclusions: The Arch of Charles Maguerez facilitated the teaching process in service. In addition, it provided the perception of the action-reflection-action movement as essential to understand fundamentals of care practices in nursing and to collaborate to the insertion of the nurse and the process of changes, from the daily services of mental health.

Background: This study aimed to investigate, through the perception of the managers, the performance of the care network of the city of João Pessoa-PB from the profile of hospitalizations for Primary Care Sensitive Conditions (ICSAP).
Methods and Findings: This is an exploratory descriptive research, with a qualitative approach, carried out with technical directors from the sanitary districts of the municipality of João Pessoa-PB. A semi-structured interview was conducted through a questionnaire containing information about personal data and planning and evaluation of management actions. The analysis was performed using Fiorin's speech analysis technique.It was possible to verify, in this research, differentiated knowledge about the health planning process, underutilization of evaluation instruments and distorted conceptions of its execution.There was also evidence of considerable fragility in the health care network and the need to consider lifelong education as a strategic element for the viability of the work process of the actors involved.
Conclusions: It was observed that the s ICSAP constitute excellent indicators for assessing performance, however underutilized and therefore should direct efforts to improve the skills, organization and integration of activities and services in health.
