OBJECTIVE

Phase-contrast MRI allows detailed measurements of various parameters of CSF motion. This examination is technically demanding and machine dependent. The literature on this topic is ambiguous. Machine learning (ML) approaches have already been successfully utilized in medical research, but none have yet been applied to enhance the results of CSF flowmetry. The aim of this study was to evaluate the possible contribution of ML algorithms in enhancing the utilization and results of MRI flowmetry in idiopathic normal pressure hydrocephalus (iNPH) diagnostics.

METHODS

The study cohort consisted of 30 iNPH patients and 15 healthy controls examined on one MRI machine. All major phase-contrast parameters were inspected: peak positive, peak negative, and average velocities; peak amplitude; positive, negative, and average flow rates; and aqueductal area. The authors applied ML algorithms to 85 complex features calculated from a phase-contrast study.

RESULTS

The most distinctive parameters with p < 0.005 were the peak negative velocity, peak amplitude, and negative flow. From the ML algorithms, the Adaptive Boosting classifier showed the highest specificity and best discrimination potential overall, with 80.4% ± 2.9% accuracy, 72.0% ± 5.6% sensitivity, 84.7% ± 3.8% specificity, and 0.812 ± 0.047 area under the receiver operating characteristic curve (AUC). The highest sensitivity was 85.7% ± 5.6%, reached by the Gaussian Naive Bayes model, and the best AUC was 0.854 ± 0.028 by the Extra Trees classifier.

CONCLUSIONS

Feature extraction algorithms combined with ML approaches simplify the utilization of phase-contrast MRI. The highest-performing ML algorithm was Adaptive Boosting, which showed good calibration and discrimination on the testing data, with 80.4% accuracy, 72.0% sensitivity, 84.7% specificity, and 0.812 AUC. Phase-contrast MRI boosted by the ML approach can help to determine shunt-responsive iNPH patients.
Machine learning to predict passenger mortality and hospital length of stay following motor vehicle collision
Authors: Kolcun John Paul G. , Covello Brian , Gernsback Joanna E. , Cajigas Iahn , Jagid Jonathan R.
Published: April 2022

OBJECTIVE

Motor vehicle collisions (MVCs) account for 1.35 million deaths and cost $518 billion US dollars each year worldwide, disproportionately affecting young patients and low-income nations. The ability to successfully anticipate clinical outcomes will help physicians form effective management strategies and counsel families with greater accuracy. The authors aimed to train several classifiers, including a neural network model, to accurately predict MVC outcomes.

METHODS

A prospectively maintained database at a single institution’s level I trauma center was queried to identify all patients involved in MVCs over a 20-year period, generating a final study sample of 16,287 patients from 1998 to 2017. Patients were categorized by in-hospital mortality (during admission) and length of stay (LOS), if admitted. All models included age (years), Glasgow Coma Scale (GCS) score, and Injury Severity Score (ISS). The in-hospital mortality and hospital LOS models further included time to admission.

RESULTS

After comparing a variety of machine learning classifiers, a neural network most effectively predicted the target features. In isolated testing phases, the neural network models returned reliable, highly accurate predictions: the in-hospital mortality model performed with 92% sensitivity, 90% specificity, and a 0.98 area under the receiver operating characteristic curve (AUROC), and the LOS model performed with 2.23 days mean absolute error after optimization.

CONCLUSIONS

The neural network models in this study predicted mortality and hospital LOS with high accuracy from the relatively few clinical variables available in real time. Multicenter prospective validation is ultimately required to assess the generalizability of these findings. These next steps are currently in preparation.
Resection of petroclival clear cell meningioma by the anterior transpetrosal approach: diagnosis of rare pathology and improvement of preoperative hearing disturbance
Authors: Matsushima Ken , Kohno Michihiro , Nakajima Nobuyuki , Ichimasu Norio , Onodera Sho , Akimoto Jiro
Published: April 2022

Clear cell meningioma is a rare histological variant of meningioma, which often recurs aggressively. This video demonstrates a patient with a petroclival clear cell meningioma, which was resected completely through the anterior transpetrosal approach. The absence of intratumoral spotty signal voids on preoperative susceptibility-weighted imaging (SWI) suggested that the tumor was a meningioma rather than a schwannoma, although typical imaging features of meningioma were not observed. After surgery, the patient’s preoperative hearing disturbance improved from class D to class A, which the authors had sometimes experienced in cerebellopontine angle meningioma surgeries. Careful observation over a 2.5-year period revealed no tumor recurrence, without additional treatment.

Combined petrosal approach for resection of a large left petroclival meningioma
Authors: Paglia Francesco , Giammattei Lorenzo , di Russo Paolo , Froelich Sebastien
Published: April 2022

Petroclival meningiomas represent the most complex lesions in skull base surgery, being closely related to critical neurovascular structures. The combined petrosal approach allows a wide exposure of the petroclival region and provides multiple angles of attack, limiting brain retraction.

The authors present the case of a 54-year-old man with a large left petroclival meningioma responsible for headaches, dysphagia, and trigeminal neuralgia. The lesion was resected using a combined petrosal approach. A progressive improvement of the preoperative symptoms was observed. Postoperative MRI showed a near-total resection of the tumor, along with reexpansion of the brainstem.

Authors: Vakharia Kunal V. , Naylor Ryan M. , Hasegawa Hirotaka , Nassiri Ashley M. , Driscoll Colin L. W. , Link Michael J.
Published: April 2022

Petroclival meningiomas, which arise from the upper two-thirds of the clivus and are medial to the trigeminal nerve, carry significant surgical risk. Patients whose operations are tailored to maximize tumor resection while minimizing neurological morbidity have favorable outcomes. Subtotally resected tumors can be subsequently considered for radiosurgery in an attempt to limit recurrence. Here the authors report the case of a 40-year-old woman with postpartum trigeminal neuropathy secondary to a petroclival meningioma. The patient underwent an aggressive subtotal resection via a posterior petrosal approach with preservation of neurological function followed by adjuvant radiosurgery.

Endoscopic endonasal transpetroclival approach for recurrent bilateral petroclival meningioma
Authors: Shinya Yuki , Shin Masahiro , Hasegawa Hirotaka , Koizumi Satoshi , Kin Taichi , Kondo Kenji , Saito Nobuhito
Published: April 2022

The authors performed an endoscopic endonasal transpetroclival approach for recurrent bilateral petroclival meningioma, with the aim of sufficient tumor resection with cranial nerve functional preservation. The tumor was sufficiently removed with excellent postoperative course. Petroclival meningioma, especially located in the medial region with dural attachment of the clivus, is considered a good indication for this approach. Recurrent tumors after radiotherapy often have strong adhesion to the brainstem and basilar artery; therefore, careful assessment of whether or not tumor detachment is possible is essential. The endoscopic endonasal transpetroclival approach is an acceptable, less-invasive treatment for petroclival tumors.

Microsurgical resection of a large petroclival meningioma via translabyrinthine approach combined with middle fossa craniotomy
Authors: Keleş Abdullah , Armstrong Stephanie Alyse , Sayyahmelli Sima , Gürbüz Mehmet Sabri , Başkaya Mustafa Kemal
Published: April 2022

Petroclival meningiomas arise from the upper two-thirds of the clivus at the petroclival junction and are reached via various approaches. As petroclival meningiomas expand, they displace the brainstem and basilar artery toward the contralateral side. Because of their proximity to critical structures and deep skull base location, surgical treatment is challenging. Although several approaches have been introduced, their rationales vary. Herein, the authors demonstrate microsurgical resection of a large petroclival meningioma via a translabyrinthine approach combined with middle fossa craniotomy. For each approach, the pros and cons should be carefully evaluated based on the patient’s presentation and lesion characteristics.

Modified Dolenc-Kawase anterior petrous rhomboid approach for petroclival meningioma: surgical nuances and complication avoidance
Authors: Suri Ashish , Sharma Ravi , Katiyar Varidh , Raheja Amol
Published: April 2022

Resection of petroclival meningiomas has remained challenging because of the critical neurovascular structures that lie in the vicinity, and thus various surgical corridors have been explored over time to figure out the optimum approach. In this video, the authors have highlighted the operative nuances of the modified Dolenc-Kawase (MDK) anterior petrous rhomboid approach. This approach gives access to the prepontine area, Dorello’s canal, anterior petrous apex, and upper two-thirds of the clivus with better angulation and surgical flexibility. It is a versatile approach for petroclival lesions that are not extending laterally and inferiorly to the internal auditory canal.

Endoscopic-assisted combined transcrusal anterior petrosal approach for resection of large petroclival meningioma: operative video and nuances of technique
Authors: Tayebi Meybodi Ali , Liu James K.
Published: April 2022

In this illustrative video, the authors demonstrate an endoscopic-assisted combined transcrusal anterior petrosal approach for resection of a large petroclival meningioma with significant brainstem compression involving Meckel’s cave. This unique petrosal variant provides increased petroclival exposure that can potentially preserve hearing by combining a transcrusal labyrinthectomy with anterior petrosectomy (Kawase’s approach). The advantages include multidirectional angles of attack to the brainstem and petroclival region without cerebellar retraction. Endoscopic assistance allows expanded visualization into deep surgical corridors. The surgery was performed in a two-stage fashion, and a near-total resection was achieved with cranial nerve and hearing preservation. The operative nuances are demonstrated.

Authors: Wu Eva M. , Altshuler David , Chen Stephanie H. , Morcos Jacques J.
Published: April 2022

Petroclival meningiomas are challenging lesions that can be treated with several surgical approaches. The authors present a 66-year-old woman with a 1.6-cm left petroclival meningioma that was initially observed and then radiated after it grew 8 years later. Despite radiation, the tumor continued to grow to 4 cm; therefore, the patient was referred to the authors’ institution. A left anterior petrosal (Kawase) approach was performed. Postoperatively, the patient had transient cranial nerve IV and VI palsy that improved. The case presentation, surgical anatomy, operative technique, postoperative course, and different surgical approaches are reviewed. The patient gave verbal consent for participating in the surgical video.

Published: April 2022

Lymphoma is the most common malignancy to affect the orbit and is frequently a diagnostic challenge for the radiologist. Any orbital and/or ocular adnexal structure may be involved with lymphoproliferative disease, and many conditions, such as idiopathic orbital inflammation and metastatic
disease, may have a similar appearance on CT or MR imaging. Almost all ocular adnexal lymphomas are of the non-Hodgkin B-cell type. These vary in aggressiveness from the low-grade mucosa-associated lymphoid tissue type lymphoma to the highly malignant mantle-cell lymphoma, which is a disseminated
disease with a poor prognosis. In this review article, we describe the CT and MR imaging findings in the various types of ocular adnexal lymphomas, its differential diagnosis, and prognostic implications. Histopathologic and genetic characteristics are briefly covered. Treatments of some conditions
are briefly discussed.Learning Objectives: To help the reader recognize the ubiquitous imaging findings in ocular adnexal lymphoproliferative diseases and to formulate a meaningful differential diagnosis vis-a-vis conditions with similar imaging appearances.
A Radiologist’s Guide to Teeth: An Imaging Review of Dental Anatomy, Nomenclature, Trauma, Infection, and Tumors
Authors: Dean K.E.
Published: April 2022

The teeth are a common site for infection, trauma, tumors, and tumorlike lesions. Because the teeth are frequently included in the field of view of imaging studies, radiologists can serve an important role in the identification, diagnosis, and, ultimately, the management of dental disease.
This requires a level of familiarity with a wide range of diseases typical to the teeth and their supporting structures. This article provides a framework for radiologists in the approach to dental disease. Dental anatomy, development, and nomenclature are first discussed to serve as a foundation.
This is followed by a review of typical trauma patterns and the pathophysiology and imaging features of dental infections, including their complications and management. Also, a structured approach to the imaging of tumor and tumorlike entities associated with dentition is outlined.Learning
Objectives: Review dental anatomy, nomenclature, and development, and discuss diseases of the teeth and their surrounding structures, including their imaging findings.
Teologia małżeństwa w adhortacjach "Familiaris consortio" i "Amoris laetitia". Aspekty duszpasterskie
Authors: Faggioni Maurizio Pietro
Published: April 2022

Artykuł podejmuje zagadnienie ujęć teologii małżeństwa w adhortacjach Familiaris consortio oraz Amoris laetitia z punktu widzenia duszpasterstwa. Podjęty problem rozwiązywany jest przede wszystkim za pomocą metody analizy porównawczej tekstów źródłowych. W pierwszej części artykułu przedstawiono refleksję na temat kontynuacji oraz rozwoju nauczania w Kościele. Ciągłość tego rozwoju przypomina wzrost organizmu żywego, który poprzez różne etapy dochodzi do form coraz dojrzalszych. W podobny sposób adhortacja Amoris laetitia, wychodząc od nauczania zawartego w Familiaris consortio, rozwija je zgodnie ze specyficznym, nowym podejściem papieża Franciszka, przestawionym w adhortacji Evangelii Gaudium. Druga część artykułu pokazuje, że Amoris laetitia wpisuje się w tradycję nauczania Kościoła na temat małżeństwa i rodziny, współbrzmiąc z takimi dokumentami, jak: soborowa konstytucja Gaudium et spes, encyklika Humanae vitae Pawła VI, list do rodzin Gratissimam sane Jana Pawła II, a przede wszystkim adhortacja Familiaris consortio. Obydwa analizowane w artykule dokumenty postulują koncentrację na konkretnych życiowych realiach oraz przedstawiają wspólny ideał małżeństwa chrześcijańskiego, jego sakramentalności i otwartości na życie. Trzecia część artykułu, koncentrując się szczególnie na podejściu do tzw. sytuacji „nieregularnych”, pokazuje, w jaki sposób Amoris laetitia jest rozwinięciem nauczania Familiaris consortio. Rozwój doktryny przedstawiono w szerszym kontekście, prezentując nauczanie Franciszka jako kolejny etap na drodze zapoczątkowanej przez jego poprzedników, uwzględniającej „prawo stopniowości”, rozeznanie osobiste i duszpasterskie oraz integrację wiernych w sytuacjach niedoskonałych. Przeprowadzone analizy wykazały, że adhortacje Familiaris consortio oraz Amoris laetitia stanowią dwa istotne kroki na drodze Kościoła posoborowego, wyznaczonej przez konstytucję Gaudium et spes, oraz że pomiędzy dokumentami widać wyraźnie ciągłość oraz rozwój nauczania.
Martha the Hostess and Mary the Listener. A Dialogue with two Feminist Interpretations of Luke 10:38-42
Authors: Crimella Matteo
Published: April 2022

This article examines the pericope of Lk 10:38-42 through the lens of gender. It presents the specific contributions of E. Schüssler Fiorenza and also M. Perroni, both of whom have interpreted the passage according to a feminist approach. The former has developed some hermeneutical criteria while the latter has insisted on female discipleship, claiming that, for Luke, the women are believers but not missionaries. The present article turns critically on the essential points of the two commentators, showing that a careful philological and contextual analysis does not allow the episode to be read as a representation of ministry in the Church. Instead, Mary’s behaviour of placing herself at the Lord’s feet appears alienating, an action which is both surprising and contrary to the social canons. The episode lays stress on precisely this difference, showing that the two poles are not "service" and "listening" but rather "distracting preoccupations" versus a "disciple’s attitude". The behaviour of the two sisters thus functions as a mirror by which the reader is invited to discern different attitudes towards Jesus.
“Snake”, “Life” or “Mother of All Living”? The Meaning of the Name חַוָּה (Eve) And Its Role in Gen 3
Authors: Napora Krzysztof
Published: April 2022

In Gen 3:20, the redactor of the Book of Genesis reports for the second time the scene of naming the woman created by God from Adam’s rib (cf. Gen 2:21-23). The name אשׁה (woman) used by Adam in Gen 2:23 obviously relates—at least phonetically—to the noun אישׁ (man). In this way, the editor expresses the idea of a certain relationship between man and woman. The existence of a similar, simple connection between the name חַוָּה (Eve) and the title אם כל־חי (the mother of all living) is far less obvious and this conundrum has been noticed by translators and exegetes for at least 2000 years. An echo of these difficulties seems to be perceptible in the text of the Septuagint, in the writings of Philo and Josephus, in the Targums, as well as in the writings of some ancient Christian writers. This article represents one further attempt to present the panorama of modern hypotheses concerning Eve’s name and the role this naming play in Gen 3.

Artykuł przedstawia ujęcie duchowości małżeńskiej w adhortacjach apostolskich Familiaris consortio i Amoris laetitia oraz prezentuje podobieństwa i różnice dotyczące tego zagadnienia w obydwu dokumentach. Posłużono się metodą analizy tekstów źródłowych z wykorzystaniem dostępnych opracowań, a także metodą porównawczą i dedukcyjną. W pierwszej części artykułu omówione zostały pojęcia duchowości chrześcijańskiej oraz duchowości małżeńskiej. Część druga stanowi analizę adhortacji Familiaris consortio pod kątem elementów duchowości małżeńskiej. W części trzeciej przeprowadzono analizę koncepcji duchowości małżeńskiej zawartej w adhortacji Amoris laetitia, opierając się przede wszystkim na treści rozdziału dziewiątego dokumentu. Część czwarta omawia podobieństwa i różnice w nauczaniu obydwu adhortacji. Familiaris consortio i Amoris laetitia przedstawiają podobną dynamikę duchowości małżeńskiej i dobrze się uzupełniają. Jan Paweł II bardziej szczegółowo przedstawia różne formy modlitewne, natomiast Franciszek w większym stopniu skupia się na konkretnych czynach miłości.
Cryptosomes: A Novel Promising Drug Delivery System
Authors: M. Dadure Kanhaiya , G. M. Haldar Animeshchandra
Published: April 2022

Vesicular drug delivery systems might be a solution to the problem of limited bioavailability and rapid clearance of medications from the body. The four kinds of lipid-based drug delivery techniques include solid-lipid particle system, emulsion-based system, solid lipid tablet, and vesicular system. Cryptosomes are a novel vesicular drug delivery system that may solve some of the shortcomings of classic drug delivery methods, such as high stability, enhanced bioavailability, longer release, and decreased elimination of fast metabolizable drugs, among others. Cryptosome is derived from the Greek terms “Crypto,” which means “hidden,” and “Soma,” which means “body.” It’s made up of phospholipids like distearoylphosphatidylethanolamine-polyethylene glycol and distearoylphosphatidylcholine (DSPE-PEG). Vesicular systems refer to the use of vesicles as a carrier or adjuvant in a variety of applications. This research looks at several vesicular drug delivery technologies and emphasises cryptosome’s accomplishments in this area. This review will be useful to researchers working in the field of vesicular drug delivery.

Sphingosomes: Highlights of the Progressive Journey and their Application Perspectives in Modern Drug Delivery
Authors: Pawar Ganesh
Published: April 2022

Vesicular systems have shown to be highly successful carrier systems in a range of scientific domains. Sphingosomes are bilayered vesicles with an aqueous volume entirely enclosed by a membrane lipid bilayer mostly composed of natural or synthetic sphingolipid. Sphingosomes solve some of the vesicle system’s major shortcomings (liposomes, niosomes), such as instability, in vivo circulation time, and tumor loading efficacy in cancer therapy. The material was gathered using the term Sphingosomes in the Google Scholar and Scopus databases. Sphingosomes are used to deliver chemotherapeutic drugs, biological macromolecules, and diagnostics in clinical settings. As a consequence of their size and composition flexibility, many types of sphingosomes have been developed. According to the conclusions of this research, sphingosomes are a possible vesicular drug delivery system that might carry medicinal compounds for a range of applications.
Hepatoprotective Potentials of Some Emerging Indian Medicinal Plants

Published: April 2022

When more organs are added to the vertebrate system, metabolites such as bile are generated, as well as glycogen, which is then detoxified and liver proteins are made. Because of the effect on the hepatic control system, you may have some severe difficulties with your general functioning if you have liver failure. Our present emphasis is on controlling the liver’s adverse effects, particularly the damage to hepatic tissues caused by conventional medications. We also went through individual signs and symptoms of liver disease, such as lipid catabolism, concurrent viral hepatitis, retained cell water, catabolism, and fibrosis and inflammation, all over the liver, in the liver, and excess, as well as inflammation and liver sickness, in particular. Different plant extracts (such as flavonoids, tannins, and vitamins) that have hepatoprotective properties, as well as the components that contribute to them, are discussed in this review article

Artificial selection of spring vetch began with hybrid materials selected from the nursery of the F1 hybrids. When studying spring vetch on different backgrounds, there was a significant difference between the offspring in terms of plant survival rate: against the background of oats, its values ranged from 21.8 to 34.4 % with an average of 27.5 %, and after white mustard - from 40 .2 to 53.35 % at - 47.2 %. Stabilization of the competitiveness of spring vetch in mixed sowing with oats was not observed, but there was a decrease in the share of full-fledged plants of the artificial population F4 from 0.5 to 7.9% compared to F3. There were more full-fledged spring vetch plants against the background of mustard, it was indicates that mustard has much lower competitiveness compared to oats. It was found that in each population plants with low productivity prevailed both after oats and after white mustard. The selection coefficient (per a sheaf) averaged from 19 % against background oats and up to 34.1 % - after white mustard, a total of 2240 elite plants were selected. Thus, at the first stage, spring vetch plants survived under cultivation with a supporting crop were selected. The survival rate of spring vetch in the agrocenosis with oats varied from 17.3 to 31.3 %. 2054 elite plants were obtained. The second stage of the artificial selection nursery was formed from the material of spring vetch which was tested for resistance to the competitive background of the previous year. The survival rate of spring vetch plants varied from 17.6 % to 24.5 %, 2432 elite plants were obtained. At the third stage, the offspring of spring vetch in mixed sowing with oat and white mustard was studied: 546 elite plants against the background of oat and 1694 against the background of white mustard were selected, with a total of 2240 elite plants selected. The percentage of selected plants indicates that spring vetch genotypes which cannot compete with the supporting crops and between themselves are eliminated from the population. Purposeful selection of artificial hybrid population of spring vetch promotes the formation of genetically balanced lines with increased resistance to abiotic environmental factors. Key words: spring vetch, hybrid, selection, productivity, mixed sowing.
The Politics of Employment in South Africa under the African National Congress: An Afrocentric perspective
Authors: B. Rapanyane Makhura , R. Sethole Florence , M. Tirivangasi Happy , S. Mugambiwa Shingirai
Published: April 2022

The rate of unemployment (state of being unemployed) in South Africa continues to rise yearly and the youth of South Africa continue to suffer at the hands of the leading Party, the African National Congress (ANC). This article adopts the Afrocentric theory to unpack the realities of the current state of employment in South Africa. The authors argue that it is currently uneasy for youth and tertiary graduates to get employment. Some of the reasons outlined in the article include favouritism, corruption and nepotism that continue to haunt the ANC almost three decades in power. The systematic politics of employment in South Africa does not favour the ordinary citizens in dire need of jobs. This article’s central argument is that government vacancies that are regularly advertised are not often awarded to deserving individuals, but individuals aligned to the ruling ANC party. Methodologically, this paper relied heavily on document study.
Interaktionen in Kindertageseinrichtungen während der Corona-Pandemie – Elternkooperation, Fachkraft-Kind-Interaktionen und das Zusammenspiel der Kinder im Rahmen eingeschränkter Möglichkeiten

Published: April 2022

Die Corona-Pandemie machte es erforderlich, dass Kindertageseinrichtungen ihr Angebot kurzfristig umstellen und unterschiedlichste Schutz- und Hygienemaßnahmen umsetzen mussten. Welche Auswirkungen diese Maßnahmen auf die Interaktionsebenen der pädagogischen Praxis hatten, wird mit Blick auf den Umgang der Fachkräfte mit den Kindern, das Zusammenspiel der Kinder untereinander und auf die Kooperation der Einrichtung mit den Eltern untersucht. Datenbasis bildet eine wiederholte, schriftliche Befragung von 2.529 Kitaleitungen im Zeitraum von Oktober 2020 bis Juni 2021, welche sowohl aktuelle als auch retrospektive Einschätzungen der Leitungskräfte bezüglich der Qualität unterschiedlicher Interaktionsebenen erfragt. Die Ergebnisse zeigen, dass die Einführung spezifischer, coronabedingter Maßnahmen, wie etwa das Distanzgebot, das Tragen von Masken oder ein Betretungsverbot der Kita für Eltern, mit einer signifikanten Verschlechterung der Beurteilung unterschiedlicher Interaktionsebenen einhergehen. Positivere Beurteilungen gingen hingegen mit einer häufigeren, auch nicht persönlichen Kommunikation mit Eltern und Kindern einher. Zudem zeigte sich, dass insbesondere Leitungen von Einrichtungen mit einem hohen Anteil an sozial benachteiligten Kindern von einer Verschlechterung berichten.
„Wir als Geschwister hatten manchmal auch Rangeleien und so, aber das waren die Geschwister und dort… das waren alles Fremde“. Der Einfluss der Fremdunterbringung auf Geschwisterbeziehungen am Beispiel von Normalkinderheimen der DDR
Authors: Schliwa Constanze Reila
Published: April 2022

Der vorliegende Beitrag fokussiert auf ehemalige Heimkinder, die getrennt von ihren Geschwistern in Normalkinderheimen der DDR aufwuchsen. Ausgehend von Oral History-Interviews wird exemplarisch untersucht, welchen Einfluss die Fremdunterbringung von Geschwistern auf ihre Beziehung hat. Gleichwohl mit diesem Artikel lediglich Einzelfälle vorgestellt werden können, machen die Narrationen dieser Zeitzeug*innen deutlich, dass Geschwisterbeziehungen trotz räumlicher Distanz nicht an Bedeutung verlieren oder gar durch Bindungen an ‚soziale‘ Geschwister ersetzt werden können. Zunächst wird herausgearbeitet, wie die Interviewpartner*innen die Beziehungen zu ihren Geschwistern vor, während und nach der Zeit im Heim beschreiben. Daran anschließend werden die Beziehungsmuster miteinander verglichen und unter Einbezug neuerer Studien diskutiert.

To evaluate the biological impacts of high background radiation exposures that are represented by spontaneous deoxyribonucleic acid (DNA) damage, an evaluation on lymphocyte cells from residents of Mamuju, West Sulawesi, Indonesia was tested. The mean annual dose received by individuals in this area is about 10.40 mSv. Of the 177 adult subjects studied, 102 were from high-level natural radiation areas of Mamuju and 75 subjects were from a nearby normal-level natural radiation area. Both areas are similar in living situations. DNA strand breaks and other parameters of study and control group were determined using a standardized comet assay.
