Published: July 2019

The aim of this work is to evaluate the antioxidant effects of the extracts of Pistacia atlantica collected in the Khenifra region (Morocco) in 2016. Different methods were used to study these extract: 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, the ferric reducing ability of plasma (FRAP) assay, the phosphomolybdate method for determining the total antioxidant capacity, and the electrochemical method for cyclic voltammetry were employed to evaluate the antioxidant capacity of Pistacia atlantica Desf. Phytochemical screening helped us to highlight the presence of secondary metabolites. The extraction of the phenolic compounds was carried out by the Soxhlet method in the presence of different mixtures solvents (ethanol/water and methanol/water); the fractions of the different extracts were affected using ethyl acetate and n-butanol. The dosage results showed that the ethanolic extract was rich in total phenols (260.4 mg GAE/g of the extract) and in total flavonoids (129.15 mg QE/g of the extract), while the butanolic fraction was rich in condensed tannin (50.96 mg CE/g of the extract). The qualitative analysis was performed by high performance liquid chromatography (HPLC). The main compounds that were identified in the methanolic and ethanolic extracts of Pistacia atlantica Desf were ascorbic acid, gallic acid, tannic acid, rutin, and quercetin. The results of the antioxidant activity revealed that the butanolic and ethyl acetate fractions exhibit a good iron reduction capacity (concentration that gave half maximal response, EC50 = 0.02 mg/ml and 0.03 mg/ml, respectively) and a very interesting antiradical activity with an IC50 (concentration of inhibitor where the response is reduced by half) = 0.08 mg/ml and 0.04 mg/ml, respectively. Cyclic voltammetry presented a single oxidation peak between 400 and 500 mV. The ethanolic and methanolic extracts were recorded from the oxidation currents values of 15.75 and 10.41 i/μA cm.2 respectively at the concentration 0.1 mg/ml. Hence, it is clear that the leaves of Pistacia atlantica Desf, which are currently often considered as potential antioxidants, contain antioxidants that can usefully be extracted and added to foods.

Ce travail vise de comparer, pour la première fois, l’activité insecticide des huiles essentielles des espèces de thyms originaires du Sud-Ouest marocain (Thymus satureioides Coss., Thymus broussonetii Boiss., Thymus maroccanus Ball., Thymus ciliatus (Desf.) Benth., Thymus pallidus Batt., et Thymus leptobotrys Murb. L’étude de la toxicité de ces huiles essentielles a été réalisée par le test de contact sur papier-filtre. Les résultats obtenus ont montré que toutes les huiles essentielles testées ont présenté un effet insecticide important vis-à-vis des adultes de Tribolium castaneum Herbst. Toutefois, l’huile essentielle de Thymus leptobotrys (thym à carvacrol) a montré la toxicité la plus élevée, avec des valeurs de DL50 et DL90 de 0,08 et 0,19 μl/cm2, respectivement, et des valeurs de LT50 et LT90, allant de 32,80 à 17,18 heures et de 69,37 à 32,05 heures, respectivement. Ces données suggèrent que les huiles essentielles de ces thyms, particulièrement celle de Thymus leptobotrys, peuvent présenter une matière première pour le développement de nouveaux produits bio-insecticides contre Tribolium castaneum, l’un des principaux ravageurs des denrées alimentaires stockées dans l’Afrique du Nord.

Published: July 2019

OBJECTIVE

The benefits and utility of routine neuromonitoring with motor and somatosensory evoked potentials during lumbar spine surgery remain unclear. This study assesses measures of performance and utility of transcranial motor evoked potentials (MEPs) during lumbar pedicle subtraction osteotomy (PSO).

METHODS

This is a retrospective study of a single-surgeon cohort of consecutive adult spinal deformity (ASD) patients who underwent lumbar PSO from 2006 to 2016. A blinded neurophysiologist reviewed individual cases for MEP changes. Multivariate analysis was performed to determine whether changes correlated with neurological deficits. Measures of performance were calculated.

RESULTS

A total of 242 lumbar PSO cases were included. MEP changes occurred in 38 (15.7%) cases; the changes were transient in 21 cases (55.3%) and permanent in 17 (44.7%). Of the patients with permanent changes, 9 (52.9%) had no recovery and 8 (47.1%) had partial recovery of MEP signals. Changes occurred at a mean time of 8.8 minutes following PSO closure (range: during closure to 55 minutes after closure). The mean percentage of MEP signal loss was 72.9%. The overall complication rate was 25.2%, and the incidence of new neurological deficits was 4.1%. On multivariate analysis, MEP signal loss of at least 50% was not associated with complication (p = 0.495) or able to predict postoperative neurological deficits (p = 0.429). Of the 38 cases in which MEP changes were observed, the observation represented a true-positive finding in only 3 cases. Postoperative neurological deficits without MEP changes occurred in 7 cases. Calculated measures of performance were as follows: sensitivity 30.0%, specificity 84.9%, positive predictive value 7.9%, and negative predictive value 96.6%. Regarding the specific characteristics of the MEP changes, only a signal loss of 80% or greater was significantly associated with a higher rate of neurological deficit (23.0% vs 0.0% for loss of less than 80%, p = 0.021); changes of less than 80% were not associated with postoperative deficits.

CONCLUSIONS

Neuromonitoring has a low positive predictive value and low sensitivity for detecting new neurological deficits. Even when neuromonitoring is unchanged, patients can still have new neurological deficits. The utility of transcranial MEP monitoring for lumbar PSO remains unclear but there may be advantages to its use.
A review on the reliability of hemodynamic modeling in intracranial aneurysms: why computational fluid dynamics alone cannot solve the equation
Authors: Berg Philipp , Saalfeld Sylvia , Voß Samuel , Beuing Oliver , Janiga Gábor
Published: July 2019

Computational blood flow modeling in intracranial aneurysms (IAs) has enormous potential for the assessment of highly resolved hemodynamics and derived wall stresses. This results in an improved knowledge in important research fields, such as rupture risk assessment and treatment optimization. However, due to the requirement of assumptions and simplifications, its applicability in a clinical context remains limited.

This review article focuses on the main aspects along the interdisciplinary modeling chain and highlights the circumstance that computational fluid dynamics (CFD) simulations are embedded in a multiprocess workflow. These aspects include imaging-related steps, the setup of realistic hemodynamic simulations, and the analysis of multidimensional computational results. To condense the broad knowledge, specific recommendations are provided at the end of each subsection.

Overall, various individual substudies exist in the literature that have evaluated relevant technical aspects. In this regard, the importance of precise vessel segmentations for the simulation outcome is emphasized. Furthermore, the accuracy of the computational model strongly depends on the specific research question. Additionally, standardization in the context of flow analysis is required to enable an objective comparison of research findings and to avoid confusion within the medical community. Finally, uncertainty quantification and validation studies should always accompany numerical investigations.

In conclusion, this review aims for an improved awareness among physicians regarding potential sources of error in hemodynamic modeling for IAs. Although CFD is a powerful methodology, it cannot provide reliable information, if pre- and postsimulation steps are inaccurately carried out. From this, future studies can be critically evaluated and real benefits can be differentiated from results that have been acquired based on technically inaccurate procedures.
Computational fluid dynamics as a risk assessment tool for aneurysm rupture
Authors: Murayama Yuichi , Fujimura Soichiro , Suzuki Tomoaki , Takao Hiroyuki
Published: July 2019

OBJECTIVE

The authors reviewed the clinical role of computational fluid dynamics (CFD) in assessing the risk of intracranial aneurysm rupture.

METHODS

A literature review was performed to identify reports on CFD assessment of aneurysms using PubMed. The usefulness of various hemodynamic parameters, such as wall shear stress (WSS) and the Oscillatory Shear Index (OSI), and their role in aneurysm rupture risk analysis, were analyzed.

RESULTS

The authors identified a total of 258 published articles evaluating rupture risk, growth, and endovascular device assessment. Of these 258 articles, 113 matching for CFD and hemodynamic parameters that contribute to the risk of rupture (such as WSS and OSI) were identified. However, due to a lack of standardized methodology, controversy remains on each parameter’s role.

CONCLUSIONS

Although controversy continues to exist on which risk factors contribute to predict aneurysm rupture, CFD can provide additional parameters to assess this rupture risk. This technology can contribute to clinical decision-making or evaluation of efficacy for endovascular methods and devices.
Hemodynamic and morphological characteristics of a growing cerebral aneurysm
Authors: Dabagh Mahsa , Nair Priya , Gounley John , Frakes David , Gonzalez L. Fernando , Randles Amanda
Published: July 2019

The growth of cerebral aneurysms is linked to local hemodynamic conditions, but the driving mechanisms of the growth are poorly understood. The goal of this study was to examine the association between intraaneurysmal hemodynamic features and areas of aneurysm growth, to present the key hemodynamic parameters essential for an accurate prediction of the growth, and to gain a deeper understanding of the underlying mechanisms. Patient-specific images of a growing cerebral aneurysm in 3 different growth stages acquired over a period of 40 months were segmented and reconstructed. A unique aspect of this patient-specific case study was that while one side of the aneurysm stayed stable, the other side continued to grow. This unique case enabled the authors to examine their aims in the same patient with parent and daughter arteries under the same inlet flow conditions. Pulsatile flow in the aneurysm models was simulated using computational fluid dynamics and was validated with in vitro experiments using particle image velocimetry measurements. The authors’ detailed analysis of intrasaccular hemodynamics linked the growing regions of aneurysms to flow instabilities and complex vortex structures. Extremely low velocities were observed at or around the center of the unstable vortex structure, which matched well with the growing regions of the studied cerebral aneurysm. Furthermore, the authors observed that the aneurysm wall regions with a growth greater than 0.5 mm coincided with wall regions of lower (< 0.5 Pa) time-averaged wall shear stress (TAWSS), lower instantaneous (< 0.5 Pa) wall shear stress (WSS), and high (> 0.1) oscillatory shear index (OSI). To determine which set of parameters can best identify growing and nongrowing aneurysms, the authors performed statistical analysis for consecutive stages of the growing CA. The results demonstrated that the combination of TAWSS and the distance from the center of the vortical structure has the highest sensitivity and positive predictive value, and relatively high specificity and negative predictive value. These findings suggest that an unstable, recirculating flow structure within the aneurysm sac created in the region adjacent to the aneurysm wall with low TAWSS may be introduced as an accurate criterion to explain the hemodynamic conditions predisposing the aneurysm to growth. The authors’ findings are based on one patient’s data set, but the study lays out the justification for future large-scale verification. The authors’ findings can assist clinicians in differentiating stable and growing aneurysms during preinterventional planning.

Published: July 2019

Intracranial aneurysms (IAs) are a result of complex interactions between biochemical and mechanical forces and can lead to significant morbidity if they rupture and cause subarachnoid hemorrhage. This review explores the role of matrix metalloproteinases (MMPs) in the pathogenesis and progression of IAs. In addition to providing a review of the normal function of MMPs, it is intended to explore the interaction between inflammation and abnormal blood flow and the resultant pathological vascular remodeling processes seen in the development and rupture of IAs. Also reviewed is the potential for the use of MMPs as a diagnostic tool for assessment of aneurysm development and progression.

Published: July 2019

Cerebral aneurysm rupture is a devastating event resulting in subarachnoid hemorrhage and is associated with significant morbidity and death. Up to 50% of individuals do not survive aneurysm rupture, with the majority of survivors suffering some degree of neurological deficit. Therefore, prior to aneurysm rupture, a large number of diagnosed patients are treated either microsurgically via clipping or endovascularly to prevent aneurysm filling. With the advancement of endovascular surgical techniques and devices, endovascular treatment of cerebral aneurysms is becoming the first-line therapy at many hospitals. Despite this fact, a large number of endovascularly treated patients will have aneurysm recanalization and progression and will require retreatment. The lack of approved pharmacological interventions for cerebral aneurysms and the need for retreatment have led to a growing interest in understanding the molecular, cellular, and physiological determinants of cerebral aneurysm pathogenesis, maturation, and rupture. To this end, the use of animal cerebral aneurysm models has contributed significantly to our current understanding of cerebral aneurysm biology and to the development of and training in endovascular devices. This review summarizes the small and large animal models of cerebral aneurysm that are being used to explore the pathophysiology of cerebral aneurysms, as well as the development of novel endovascular devices for aneurysm treatment.
Insufficient slow-flow suppression mimicking aneurysm wall enhancement in magnetic resonance vessel wall imaging: a phantom study
Authors: Cornelissen Bart M. W. , Leemans Eva L. , Coolen Bram F. , Peper Eva S. , van den Berg René , Marquering Henk A. , Slump Cornelis H. , Majoie Charles B. L. M.
Published: July 2019

OBJECTIVE

MR vessel wall imaging (VWI) is increasingly performed in clinical settings to support treatment decision-making regarding intracranial aneurysms. Aneurysm wall enhancement after contrast agent injection is expected to be related to aneurysm instability and rupture status. However, the authors hypothesize that slow-flow artifacts mimic aneurysm wall enhancement. Therefore, in this phantom study they assess the effect of slow flow on wall-like enhancement by using different MR VWI techniques.

METHODS

The authors developed an MR-compatible aneurysm phantom model, which was connected to a pump to enable pulsatile inflow conditions. For VWI, 3D turbo spin echo sequences—both with and without motion-sensitized driven equilibrium (MSDE) and delay alternating with nutation for tailored excitation (DANTE) preparation pulses—were performed using a 3-T MR scanner. VWI was acquired both before and after Gd contrast agent administration by using two different pulsatile inflow conditions (2.5 ml/sec peak flow at 77 and 48 beats per minute). The intraluminal signal intensity along the aneurysm wall was analyzed to assess the performance of slow-flow suppression.

RESULTS

The authors observed wall-like enhancement after contrast agent injection, especially in low pump rate settings. Preparation pulses, in particular the DANTE technique, improved the performance of slow-flow suppression.

CONCLUSIONS

Near-wall slow flow mimics wall enhancement in VWI protocols. Therefore, VWI should be carefully interpreted. Preparation pulses improve slow-flow suppression, and therefore the authors encourage further development and clinical implementation of these techniques.
Novel diffusion tractography methodology using Kalman filter prediction to improve preoperative benefit-risk analysis in pediatric epilepsy surgery
Authors: Lee Min-Hee , O’Hara Nolan B. , Motoi Hirotaka , Luat Aimee F. , Juhász Csaba , Sood Sandeep , Asano Eishi , Jeong Jeong-Won
Published: July 2019

OBJECTIVE

In this study the authors investigated the clinical reliability of diffusion weighted imaging maximum a posteriori probability (DWI-MAP) analysis with Kalman filter prediction in pediatric epilepsy surgery. This approach can yield a suggested resection margin as a dynamic variable based on preoperative DWI-MAP pathways. The authors sought to determine how well the suggested margin would have maximized occurrence of postoperative seizure freedom (benefit) and minimized occurrence of postoperative neurological deficits (risk).

METHODS

The study included 77 pediatric patients with drug-resistant focal epilepsy (age 10.0 ± 4.9 years) who underwent resection of their presumed epileptogenic zone. In preoperative DWI tractography from the resected hemisphere, 9 axonal pathways, Ci=1–9, were identified using DWI-MAP as follows: C1–3 supporting face, hand, and leg motor areas; C4 connecting Broca’s and Wernicke’s areas; C5–8 connecting Broca’s, Wernicke’s, parietal, and premotor areas; and C9 connecting the occipital lobe and lateral geniculate nucleus. For each Ci, the resection margin, di, was measured by the minimal Euclidean distance between the voxels of Ci and the resection boundary determined by spatially coregistered postoperative MRI. If Ci was resected, di was assumed to be negative (calculated as –1 × average Euclidean distance between every voxel inside the resected Ci volume, ri). Kalman filter prediction was then used to estimate an optimal resection margin, d*i, to balance benefit and risk by approximating the relationship between di and ri. Finally, the authors defined the preservation zone of Ci that can balance the probability of benefit and risk by expanding the cortical area of Ci up to d*i on the 3D cortical surface.

RESULTS

In the whole group (n = 77), nonresection of the preoperative preservation zone (i.e., actual resection margin d*i greater than the Kalman filter–defined d*i) accurately predicted the absence of postoperative motor (d*1–3: 0.93 at seizure-free probability of 0.80), language (d*4–8: 0.91 at seizure-free probability of 0.81), and visual deficits (d*9: 0.90 at seizure-free probability of 0.75), suggesting that the preservation of preoperative Ci within d*i supports a balance between postoperative functional deficit and seizure freedom. The subsequent subgroup analyses found that preservation of preoperative Ci =1–4,9 within d*i =1–4,9 may provide accurate deficit predictions independent of age and seizure frequency, suggesting that the DWI-based surgical margin can be effective for surgical planning even in young children and across a range of epilepsy severity.

CONCLUSIONS

Integrating DWI-MAP analysis with Kalman filter prediction may help guide epilepsy surgery by visualizing the margins of the eloquent white matter pathways to be preserved.
Surgical management of giant presacral schwannoma: systematic review of published cases and meta-analysis
Authors: Pennington Zach , Westbroek Erick M. , Ahmed A. Karim , Cottrill Ethan , Lubelski Daniel , Goodwin Matthew L. , Sciubba Daniel M.
Published: July 2019

OBJECTIVE

Giant presacral schwannomas are rare sacral tumors found in less than 1 of every 40,000 hospitalizations. Current management of these tumors is based solely upon case reports and small case series. In this paper the authors report the results of a systematic review of the available English literature on presacral schwannoma, focused on identifying the influence of tumor size, tumor morphology, surgical approach, and extent of resection (EOR) on recurrence-free survival and postoperative complications.

METHODS

The medical literature (PubMed and EMBASE) was queried for reports of surgically managed sacral schwannoma, either involving 2 or more contiguous vertebral levels or with a diameter ≥ 5 cm. Tumor size and morphology, surgical approach, EOR, intraoperative and postoperative complications, and survival data were recorded.

RESULTS

Seventy-six articles were included, covering 123 unique patients (mean age 44.1 ± 1.4 years, 50.4% male). The most common presenting symptoms were leg pain (28.7%), lower back pain (21.3%), and constipation (15.7%). Most surgeries used an open anterior-only (40.0%) or posterior-only (30%) approach. Postoperative complications occurred in 25.6% of patients and local recurrence was noted in 5.4%. En bloc resection significantly improved progression-free survival relative to subtotal resection (p = 0.03). No difference existed between en bloc and gross-total resection (GTR; p = 0.25) or among the surgical approaches (p = 0.66). Postoperative complications were more common following anterior versus posterior approaches (p = 0.04). Surgical blood loss was significantly correlated with operative duration and tumor volume on multiple linear regression (both p < 0.001).

CONCLUSIONS

Presacral schwannoma can reasonably be treated with either en bloc or piecemeal GTR. The approach should be dictated by lesion morphology, and recurrence is infrequent. Anterior approaches may increase the risk of postoperative complications.
False localizing signs of spinal CSF–venous fistulas in spontaneous intracranial hypotension: report of 2 cases
Authors: Schievink Wouter I. , Maya M. Marcel , Moser Franklin G.
Published: July 2019

A spinal CSF–venous fistula is one of three specific types of spinal CSF leak that can be seen in patients with spontaneous intracranial hypotension (SIH). They are best demonstrated on specialized imaging, such as digital subtraction myelography (DSM) or dynamic myelography, but often they are diagnosed on the basis of increased contrast density in the draining veins (the so-called hyperdense paraspinal vein sign) on early postmyelography CT scans. The authors report on 2 patients who underwent directed treatment (surgery in one patient and glue injection in the other) based on the hyperdense paraspinal vein sign, in whom the actual site of the fistula did not correspond to the level or laterality of the hyperdense paraspinal vein sign. The authors suggest consideration of DSM or dynamic myelography prior to undertaking treatment directed at these fistulas.
The great neurosurgical masquerader: 3 cases of desmoplastic infantile ganglioglioma
Authors: Cohen Alan R.
Published: July 2019

Desmoplastic infantile ganglioglioma (DIG) is a rare, distinctive, supratentorial neoplasm with a generally favorable prognosis. Clinical, radiographic, and pathologic features can sometimes mimic those of a malignant tumor and other serious intracranial disorders. The author describes his experience with 3 cases of DIG, each of which initially masqueraded as another neurological disease with a very different prognosis. Case 1 was an infant boy referred for evaluation of a hemorrhagic infarction at birth. Case 2 was an infant girl referred for evaluation of a holohemispheric malignant neoplasm. Case 3 was an infant girl referred for evaluation of an intracranial mass believed to be a subdural empyema or possible sarcoma. In each case the lesion was resected and found to be a WHO grade I DIG. Each child has had a benign postoperative course. DIG can be mistaken for other serious neurological conditions including malignant neoplasm, cerebral infarction, and infection. It is prudent to consider this rare, low-grade resectable tumor in the differential diagnosis of atypical intracranial masses of childhood, as the impact on prognosis can be profound. The author discusses management strategies for DIG, including a role for molecular sequencing.

Based on the results of the study, it can be concluded that: First, the role of Bapas Class I Padang Community Supervisor in guiding clients of narcotics abuse has been carried out well, because the guidance provided by Bapas Class I Padang Community Supervisor is in the form of Post-Rehabilitation Program which is a follow-up stage given to narcotics addicts after undergoing rehabilitation which aims to guide the narcotics client to develop attitudes to society and not repeat it again. Secondly, the effectiveness of narcotics clients in preventing narcotics criminal acts at Padang Class I Correctional Facilities in principle can be said to be quite effective because every client who follows the Post-Rehabilitation Program does not have a client who repeats narcotics abuse. Third, Constraints faced in Narcotics Client Guidance at Padang Class I Correctional Institution are limited conditions and functions and lack of Human Resources (HR), as well as clients who have undergone rehabilitation to undergo post-rehabilitation services, many who have not been serious about recovering, because of the lack of family and community support in realizing the recovery of former addicts, and the lack of a place to channel their interests and potential to return to the social environment of the community. In addition, the demands of the client's economic needs become an element of strengthening the absence of clients because they cannot leave their jobs which are mostly from the private sector. Besides that, budget problems are an important factor in post-rehabilitation implementation in order to run optimally.

This study aims to assess and compare the extent of corporate disclosure of the countries that have already implemented the renewal ASEAN disclosure standards with the countries that have not implemented yet. The empirical result indicates that overall picture of corporate disclosure in the ASEAN is in a good progression, with an increasing trend. Then, an independent t-test analysis addresses that the renewal ASEAN disclosure standards could have an effect on the level of corporate disclosure, especially in terms of non-financial and strategic information. But, it has no impacts on financial information. Therefore, it can be concluded that the regional disclosure standards might be one of the supportive factors for enforcing businesses to disclose more corporate information to the public. With this finding, it could alert regional regulators by providing the weaknesses of the current activities related to economic integration and guiding the direction for further development.
Gleicher Titel, ungleiche Entlohnung. Geschlechtsbezogene Lohnunterschiede unter Promovierten in Deutschland
Authors: Goldan Lea
Published: July 2019

Die bisherige Promoviertenforschung deutet darauf hin, dass Frauen monetär weniger vom Erwerb eines Doktortitels profitieren als Männer. Daher werden im vorliegenden Beitrag erstmals das Ausmaß und die Ursachen geschlechtsbezogener Lohnunterschiede unter Promovierten in Deutschland untersucht. Es wird erwartet, dass sich promovierte Frauen und Männer hinsichtlich ihrer Studienfachwahl und Beschäftigungsmerkmale unterscheiden. Auf der Grundlage des DZHW-Absolventenpanels 2001 werden die Brutto-Stundenlöhne zehn Jahre nach Studienabschluss mittels OLS-Regression und Oaxaca-Blinder-Dekomposition untersucht. Die Ergebnisse zeigen, dass die Stundenlöhne von promovierten Frauen um 16,3 Prozent geringer sind als diejenigen von promovierten Männern. Diese Lohnunterschiede sind zu zwei Dritteln darauf zurückzuführen, dass promovierte Frauen häufiger Fächer mit einem hohen Frauenanteil studiert haben, nach ihrem Studium weniger Berufserfahrung sammeln und seltener Leitungspositionen innehaben als promovierte Männer.

Ein großer Teil der Senior*innen in Deutschland zählt zu den Offliner*innen. Geringe oder fehlende Digitalkompetenz in einer sich zunehmend digitalisierenden Gesellschaft birgt das Risiko, sozial abgehängt zu werden. Insbesondere für Frauen gibt es hierbei Benachteiligungen, die im Zusammenhang mit Prozessen von Doing Gender/Doing Age und dem Zusammenspiel von Zuschreibung, Darstellung und Anerkennung stehen. Das Forschungs-Praxis-Projekt Connect-ed – Wege aus der sozialen Isolation im Kontext Neuer Medien nimmt sich der Problembereiche der sozialen Isolation und digitalen Exklusion in den Lebenssituationen älterer Menschen mit einem innovativen Weiterbildungskonzept an, das zwischenmenschliche Begegnungen im realen wie virtuellen Raum verbindet. Eine erste Auswertung der empirischen Daten, die durch Fragebögen, Netzwerkkarten und Gruppendiskussionen gewonnen wurden, ergab, dass sich im Rahmen der Weiterbildung das Wohlbefinden der Teilnehmerinnen deutlich steigerte und der Wissenserwerb im Bereich der Neuen Medien zu einem Zugewinn an Selbstständigkeit und Selbstvertrauen führte. Allerdings können digitale Netzwerke reale Begegnungen und Austausch nicht ersetzen.
