Crafting Ethnographic Relationships During the COVID-19 Pandemic in Germany Using Voice-Based Technologies.

Drawing on a two-year ethnography of care practices during the COVID-19 pandemic in Germany, we discuss the affordances of voice-based technologies (smartphones, basic mobile phones, and landline telephones) in collecting ethnographic data and crafting relationships with participants. We illustrate how such technologies allowed us to move with participants, eased data collection through the social expectations around their use, and reoriented our attention to the multiple qualities of sound. Adapting research on the performativity of technology, we argue that voice-based technologies integrated us into participants' everyday lives while also maintaining physical distance in times of infectious sociality.

Long-Term Outcome of Neonates and Infants whose Mothers Tested Positive for SARS-CoV-2 during Pregnancy - a Pilot of the Post-CRONOS Project.

OBJECTIVE: Long-term effects on infants of mothers with SARS-CoV-2 infection during pregnancy are increasingly discussed in the literature. Besides potential neurodevelopment impairments after intrauterine SARS-CoV-2 exposure, there might be differences in the postnatal pediatric care of those children, like the timing of preventive medical examinations (PME) or vaccinations. In this first national long-term follow-up study of women included in the CRONOS registry, we describe maternal impressions of their child´s development and the prevalence of regulatory disorders, and we analyze the timing of PMEs and vaccinations. METHODS: 773 women who were enrolled between April 3, 2020, and August 24, 2021, in the CRONOS registry were eligible to be contacted by the study coordinators and asked to fill out a web-based questionnaire. RESULTS: 110/773 (14%) women completed the questionnaire. Their children were between the ages of 12 and 31 months (median 20 months). All mothers were satisfied with their child´s development, milestones were achieved in a timely fashion. The reported prevalence for excessive crying, sleeping, and feeding disorders was 11%, 18-32%, and 7%, respectively. PMEs were mostly not delayed, but only 54% of infants received their first vaccination within their first 60 days of life. DISCUSSION: In summary, our exploratory findings suggest that developmental milestones in infancy are reached in time after maternal SARS-CoV-2 infection during pregnancy. However, there are effects on the implementation of PMEs and vaccinations. EINFüHRUNG: In der Literatur werden zunehmend potenzielle Langzeitfolgen für Säuglinge nach intrauteriner SARS-CoV-2-Exposition diskutiert. Neben möglichen Beeinträchtigungen der neurologischen Entwicklung können Unterschiede in der pädiatrischen postnatalen Betreuung bei diesen Kindern z. B. bei der Durchführung von Vorsorgeuntersuchungen (sog. U´s) oder Impfungen bestehen. In dieser ersten nationalen Langzeit-Follow-up-Studie aus dem CRONOS-Register beschreiben wir mütterliche Eindrücke zur Entwicklung ihres Kindes, sowie die Prävalenz von Regulationsstörungen. Wir analysieren den Zeitpunkt von U´s und Impfungen. METHODEN: 773 Frauen, die zwischen dem 03.04.2020 und dem 24.08.2021 in CRONOS aufgenommen wurden, wurden von den Studienkoordinatoren kontaktiert und gebeten, einen webbasierten Fragebogen auszufüllen. ERGEBNISSE: 110/773 (14%) Frauen füllten den Fragebogen aus, ihre Kinder waren zwischen 12 und 31 Monate alt (Median 20 Monate). Alle Mütter waren mit der Entwicklung ihres Kindes zufrieden, Meilensteine der Entwicklung wurden zeitgerecht erreicht. Die berichtete Prävalenz für exzessives Schreien, Schlaf- und Fütterstörungen betrug 11%, 18-32% bzw. 7%. U´s wurden meist zeitgerecht durchgeführt, aber nur 54% der Säuglinge erhielten ihre erste Impfung innerhalb der ersten 60 Lebenstage. DISKUSSION: Zusammenfassend deuten unsere explorativen Ergebnisse darauf hin, dass Entwicklungsmeilensteine im Säuglingsalter nach mütterlicher SARS-CoV-2-Infektion in der Schwangerschaft rechtzeitig erreicht werden. Es zeigen sich jedoch Auswirkungen auf die Durchführung von Vorsorgen und Impfungen.

Social health: rethinking the concept through social practice theory and feminist care ethics.

The social sciences have long shown that health is not born of pure biology, empirically (re)centred the social and material causes of disease, and affirmed the subjective experiences of disease. Disputed both in popular and academic discourses, social health has variously attempted to stress the social aspects of health. Existing conceptions remain analytically limited as they are predominantly used as descriptors for populational health. This article theorises social health as an analytical lens for making sense of the relations, affects and events where health unfolds and comes into expression. Drawing on social practice theory, feminist care ethics and posthumanism this conceptual paper re-imagines how social health might be conceived as lived social practices anchored in care. Care within our framework acknowledges the unavoidable interdependency foundational to the existence of beings and stresses the 'know how' and embodied practices of care in the mundane in order to emphasise that care itself is absolutely integral to the maintenance of social health. The article argues that health needs to be understood as a verb intrinsically (re)made in and through social contexts and structures and comprised of meaningful, human-human and human-non-human interactions. Ultimately, in theorising social health through mundane care practices, we hope to open up research to making sense of how the doing of health unfolds inside often banal, patterned forms of social activity. Such taken-for-granted social practices exemplify the often overlooked lived realities that comprise our health. To understand health in its own right, we argue, these everyday practices need to be interrogated.

[Pandemic Management in the Context of Everyday Care and the need for Good Care: Results and Recommendations for Action from the Coronacare Workshops]. / Pandemie-Management unter Berücksichtigung des Pflegealltags und dem Bedürfnis nach guter Pflege. Ergebnisse und Handlungsempfehlungen aus den CoronaCare-Workshops.

The Covid-19 pandemic, officially declared in March 2020 by the WHO, poses major challenges to public, private, and occupational life. CoronaCare is an ethnographic research project that investigates the everyday life of people during the Covid-19 pandemic in Germany with a particular focus on social health. The aim of the project was to develop recommendations for pandemic preparedness planning focusing on expanding social health care. Through a series of workshops conducted between June and November 2021 with stakeholders from the fields of science, health and social administration drawn from both local and state levels, care institutions and social associations, the research team developed specific recommendations for pandemic preparedness and response on the basis of empirically substantiated vignettes demonstrating key tensions in caring practices. These tensions illustrate that pandemic management must be understood as a so-called wicked problem in which there are only relational rather than clear-cut, ultimate solutions. As such, the recommendations developed in the workshops point to the imperative to 1. recognize the irresolvable tension between measures to contain the pandemic in planning pandemic management and the human desire to care and be cared for; 2. understand and manage pandemics at the community level; 3. aim for close collaboration between actors at the local health, social, and family level; and 4. create spaces for ethical reflection on good care during a pandemic and develop context-specific strategies for action. For pandemic preparedness and management as a 'wicked problem', this means that measures should be disseminated as recommendations rather than regulations in order to have some leeway that enables care to be tailored to individual needs. They should be accompanied by stable guidance for action as well as regular training for staff. The workshop formats can be understood as an example of multidimensional knowledge transfer in a socially challenging situation.

Psychosocial burden in nurses working in nursing homes during the Covid-19 pandemic: a cross-sectional study with quantitative and qualitative data.

BACKGROUND: The Covid-19 pandemic led to increased work-related strain and psychosocial burden in nurses worldwide, resulting in high prevalences of mental health problems. Nurses in long-term care facilities seem to be especially affected by the pandemic. Nevertheless, there are few findings indicating possible positive changes for health care workers. Therefore, we investigated which psychosocial burdens and potential positive aspects nurses working in long-term care facilities experience during the Covid-19 pandemic. METHODS: We conducted a mixed-methods study among nurses and nursing assistants working in nursing homes in Germany. The survey contained the third German version of the Copenhagen Psychosocial Questionnaire (COPSOQ III). Using Welch's t-tests, we compared the COPSOQ results of our sample against a pre-pandemic reference group of geriatric nurses from Germany. Additionally, we conducted semi-structured interviews with geriatric nurses with a special focus on psychosocial stress, to reach a deeper understanding of their experiences on work-related changes and burdens during the pandemic. Data were analysed using thematic coding (Braun and Clarke). RESULTS: Our survey sample (n = 177) differed significantly from the pre-pandemic reference group in 14 out of 31 COPSOQ scales. Almost all of these differences indicated negative changes. Our sample scored significantly worse regarding the scales 'quantitative demands', 'hiding emotions', 'work-privacy conflicts', 'role conflicts', 'quality of leadership', 'support at work', 'recognition', 'physical demands', 'intention to leave profession', 'burnout', 'presenteeism' and 'inability to relax'. The interviews (n = 15) revealed six main themes related to nurses' psychosocial stress: 'overall working conditions', 'concern for residents', 'management of relatives', 'inability to provide terminal care', 'tensions between being infected and infecting others' and 'technicisation of care'. 'Enhanced community cohesion' (interviews), 'meaning of work' and 'quantity of social relations' (COPSOQ III) were identified as positive effects of the pandemic. CONCLUSIONS: Results clearly illustrate an aggravation of geriatric nurses' situation and psychosocial burden and only few positive changes due to the Covid-19 pandemic. Pre-existing hardships seem to have further deteriorated and new stressors added to nurses' strain. The perceived erosion of care, due to an overemphasis of the technical in relation to the social and emotional dimensions of care, seems to be especially burdensome to geriatric nurses.

CoronaCare study protocol: an ethnographic study of the risks to and potential for social health during the COVID-19 pandemic.

INTRODUCTION: German government regulations such as physical distancing and limited group numbers, designed to curb the spread of COVID-19, have had far-reaching consequences for the very foundations of social life. They have, to name only a few, transformed greetings and goodbyes, blurred private and public worlds, and complicated basic communication with mandatory mask wearing. The ethnographic study CoronaCare investigates how these sociopolitical measures affect social health, a form of health which unfolds through and across social relations. It explores how caring as a fundamental human activity and one integral to sustaining social health is impacted when in-person and person-to-person contacts are restricted and everyone is radically redefined as at risk from others and a risk to others. It explores care relationships, relationships involving the giving or receiving of care in everyday life, institutional settings such as an assisted living facility, and informal settings, such as a housing block. Inside of the pandemic, relationships are a pivotal site at which the negotiation of caring and risk is intensified and where the consequences for social health and social life more generally are pronounced. METHODS AND ANALYSIS: This ethnographic project aims to understand the tensions that arise in the lives of individuals and communities living under the sociopolitical regulations and to analyse the tacit forms of practice that individuals and communities develop to uphold social health. Fueled by citizen science, the ethnography uses a variety of methods namely telephone and video interviews with 60-70 research participants, the collection of ethnographic material including video and audio diaries, storyboards, first-person camera footage, photographs and a survey to enrich the sample description based on the Copenhagen Psychosocial Questionnaire. The analysis will draw on elements of grounded theory and through the aid of the qualitative software MAXQDA it will rigorously document and explain how the social regulations are (re)shaping our ability to be cared for and to care for one another. The survey data will be analysed through the use of the quantitative software programme R. ETHICS AND DISSEMINATION: The ethics committee of the Brandenburg Medical School Theodor Fontane has approved the project (E-01-20200605). The dissemination strategy includes publications in medical, sociological and research methods journals, as well as a stakeholder discussion with political and civil society leaders where the research team will present its recommendations for future pandemic preparedness.

[The development and application of conflict-specific story completion tasks as part of OPD diagnostics in childhood]. / Die Entwicklung und Anwendung konfliktspezifischer Geschichtenergänzungsaufgaben als Teil der OPD-Diagnostik im Kindesalter.

The development and application of conflict-specific story completion tasks as part of OPD diagnostics in childhood Abstract. The study combines use of the MacArthur Story Stem Battery (MSSB) with the Operationalized Psychodynamic Diagnostics in Childhood and Adolescence (OPD-CA-2). It describes the development and application of conflict-specific story completion tasks, which are meant to enable a systematic evaluation of the conflict axis and the structure axis of Age Group 2. It determines interrater reliability for the conflict axis and the structure axis and checks further exploratory correlations between conflict axis and structure axis using the SDQ (Strengths and Difficulties Questionnaire). The diagnostic method presented here enables a reliable evaluation of the conflict axis and the structure axis. Moreover, correlations occur between the OPD-CA-2 axes and the SDQ.

Influence of residual fat signal on diffusion kurtosis MRI of suspicious mammography findings.

Recent studies showed the potential of diffusion kurtosis imaging (DKI) as a tool for improved classification of suspicious breast lesions. However, in diffusion-weighted imaging of the female breast, sufficient fat suppression is one of the main factors determining the success. In this study, the data of 198 patients examined in two study centres was analysed using standard diffusion and kurtosis evaluation methods and three DKI fitting approaches accounting phenomenologically for fat-related signal contamination of the lesions. Receiver operating characteristic curve analysis showed the highest area under the curve (AUC) for the method including fat correction terms (AUC = 0.85, p < 0.015) in comparison to the values obtained with the standard diffusion (AUC = 0.77) and kurtosis approach (AUC = 0.79). Comparing the two study centres, the AUC value improved from 0.77 to 0.86 (p = 0.036) using a fat correction term for the first centre, while no significant difference with no adverse effects was observed for the second centre (AUC 0.89 vs. 0.90, p = 0.95). Contamination of the signal in breast lesions with unsuppressed fat causing a reduction of diagnostic performance of diffusion kurtosis imaging may potentially be counteracted by proposed adapted evaluation methods.

Advanced Diffusion-Weighted Abdominal Imaging: Qualitative and Quantitative Comparison of High and Ultra-High b-Values for Lesion Detection and Image Quality.

INTRODUCTION: Magnetic resonance imaging (MRI) of the abdomen increasingly incorporates diffusion-weighted imaging (DWI) sequences. Whereas DWI can substantially aid in detecting and characterizing suspicious findings, it remains unclear to what extent the use of ultra-high b-value DWI might further be of aid for the radiologist especially when using DWI sequences with advanced processing. The target of this study was therefore to compare high and ultra-high b-value DWI in abdominal MRI examinations. METHODS: This institutional review board-approved, prospective study included abdominal MRI examinations of 70 oncologic patients (mean age, 58 years; range, 21-90 years) examined with a clinical 1.5 T MRI scanner (MAGNETOM Aera, Siemens Healthcare, Erlangen, Germany) with an advanced echo planar DWI sequence (b = 0, 50, 900, and 1500 s/mm) after ex vivo phantom and in vivo volunteer investigations. High b900 and ultra-high b1500 DWIs were compared by a qualitative reading for image quality and lesion conspicuity using a 5-point Likert scale with 2 radiologists as readers. The ratios of apparent signal intensities of suspicious lesions/normal tissue of the same organ (LNTRs) were calculated. Appropriate methods were used for statistical analysis, including Wilcoxon signed-rank test and κ statistic for interreader agreement analysis (P < 0.05/0.0125/0.005 after Bonferroni correction). RESULTS: Image quality was significantly increased with b900 as compared with b1500 DWI (P < 0.001) despite using an advanced DWI sequence. A total of 153 suspicious lesions were analyzed. Overall reader confidence for characterization/detection of malignant lesions and, correspondingly, the LNTR (mean, 2.7 ± 1.8 vs 2.4 ± 1.6) were significantly higher with b900 than with b1500 DWI (P < 0.001 and P < 0.001). The increased confidence of lesion recognition and LNTR in the b900 DWI remained significant qualitatively in lymphatic and hepatic lesions and quantitatively in lymphatic, pulmonal, and osseous lesions. CONCLUSIONS: Using high b-value DWI (900 s/mm) provided an improved image quality and also lesion conspicuity as compared with ultra-high b-value DWI (1500 s/mm) in oncologic abdominal examinations despite using advanced processing. Consequently, the value for additional ultra-high b-value DWI in oncologic examinations should be critically evaluated in future studies.

Modulating Diffusion-Weighted Magnetic Resonance Imaging for Screening in Oncologic Tertiary Prevention: A Prospective Ex Vivo and In Vivo Study.

INTRODUCTION: Diffusion-weighted imaging (DWI) is an important part of oncological magnetic resonance imaging (MRI) examinations, especially for tertiary cancer prevention in terms of early detection of recurrent disease. However, abdominal studies can be challenged by motion artifacts, poor signal-to-noise ratios, and visibility of retroperitoneal structures, which necessitates sequence optimization depending on the investigated region. This study aims at prospectively evaluating an adapted DWI sequence ex vivo and in vivo in oncologic patients undergoing abdominal MRI. METHODS: This institutional review board-approved, prospective study included phantom measurements, volunteer examinations, and oncologic patient examinations of the abdomen. Fifty-seven MRI examinations in 54 patients (mean age, 58 years; range, 21-90 years) were included into the analysis. The MRI examination were performed at a 1.5 T MRI scanner (MAGNETOM Aera; Siemens Healthcare, Erlangen, Germany) and included both a standard EPI-DWI (s-DWI; b = 50, 900 s/mm) and an adapted DWI (opt-DWI; EPI-DWI with b = 0, 50, 900, 1500 s/mm, acquisition with higher spatial resolution and optimized processing for the abdomen including motion correction, adaptive image combination, and background suppression). For b = 900 s/mm, the ratio of signal intensity in the normal tissue and the standard deviation of the noise in the surrounding air was quantitatively calculated; image quality and tissue differentiation parameters were rated by 2 independent, blinded readers using a 5-point Likert scale. Statistics included Wilcoxon signed-rank test and kappa statistic (P < 0.05/0.0125 after Bonferroni correction). RESULTS: The DWI phantom demonstrated an optimized contour sharpness and inlay differentiation for opt-DWI. The apparent ratio of normal tissue signal/standard deviation of background noise at b = 900 s/mm of the right/left hemiabdomen was significantly increased in opt-DWI (mean, 71.9 ± 23.5/86.0 ± 43.3) versus s-DWI (mean, 51.4 ± 15.4/63.4 ± 36.5; P < 0.001). Image quality parameters (contour sharpness and tissue differentiation of upper abdominal and retroperitoneal structures) were significantly increased in opt-DWI versus s-DWI (P < 0.001). Interreader reliability test showed good agreement (kappa = 0.768; P < 0.001). DISCUSSION: This study prospectively evaluated the potential of adapted DWI for screening in tertiary prevention of oncologic patients. An optimized DWI protocol with advanced processing achieved improved image quality in quantitative and qualitative analyses. Oncological optimization of DWI should be performed before its application in cancer patients to improve both screening and follow-up examinations, to better unleash the diagnostic potential of DWI.

The CoLaPipe--the new Cottbus large pipe test facility at Brandenburg University of Technology Cottbus-Senftenberg.

The CoLaPipe is a novel test facility at the Department of Aerodynamics and Fluid Mechanics, Brandenburg University of Technology Cottbus-Senftenberg (BTU Cottbus-Senftenberg), set up to investigate fully developed pipe flow at high Reynolds numbers (Re(m) ⩽ 1.5 × 10(6)). The design of the CoLaPipe is closed-return with two available test sections providing a length-to-diameter ratio of L/D = 148 and L/D = 79. Within this work, we introduce the CoLaPipe and describe the various components in detail, i.e., the settling chamber, the inlet contraction, the blower, bends, and diffusers as well as the cooling system. A special feature is the numerically optimized contraction design. The applications of different measuring techniques such as hot-wire anemometry and static pressure measurements to quantitatively evaluate the mean flow characteristics and turbulence statistics are discussed as well. In addition, capabilities and limitations of available and new pipe flow facilities are presented and reconsidered based on their length-to-diameter ratio, the achieved Reynolds numbers, and the resulting spatial resolution. Here, the focus is on the facility design, the presentation of some basic characteristics, and its contribution to a reviewed list of specific questions still arising, e.g., scaling and structural behavior of turbulent pipe flow as well as the influence of the development length on turbulence investigations.

Ten repeat collections for urinary iodine from spot samples or 24-hour samples are needed to reliably estimate individual iodine status in women.

Although the median urinary iodine concentration (UIC) is a good indicator of iodine status in populations, there is no established biomarker for individual iodine status. If the UIC were to be used to assess individuals, it is unclear how many repeat urine collections would be needed and if the collections should be spot samples or 24-h samples. In a prospective, longitudinal, 15-mo study, healthy Swiss women (n = 22) aged 52-77 y collected repeated 24-h urine samples (total n = 341) and corresponding fasting, second-void, morning spot urine samples (n = 177). From the UIC in spot samples, 24-h urinary iodine excretion (UIE) was extrapolated based on the age- and sex-adjusted iodine:creatinine ratio. Measured UIE in 24-h samples, estimated 24-h UIE, and UIC in spot samples were (geometric mean ± SD) 103 ± 28 µg/24 h, 86 ± 33 µg/24 h, and 68 ± 28 µg/L, respectively, with no seasonal differences. Intra-individual variation (mean CV) was comparable for measured UIE (32%) and estimated UIE (33%). The CV tended to be higher for the spot UIC (38%) than for the estimated 24-h UIE (33%) (P = 0.12). In this population, 10 spot urine samples or 24-h urine samples were needed to assess individual iodine status with 20% precision. Spot samples would likely be preferable because of their ease of collection. However, the large number of repeated urine samples needed to estimate individual iodine status is a major limitation and emphasizes the need for further investigation of more practical biomarkers of individual iodine status.
