Rays of Death and Visions of Life: Ultrasound Narratives, Risk Evaluations, and Prenatal Imaging.

Diagnostic ultrasound visualization was initially developed and introduced as a more benign alternative to X-rays and is today established as a harmless routine procedure and tool for risk management, but as this article shows, it took several decades to overcome the popular notion that ultrasound itself was a high-risk technology, a potentially deadly weapon. Swedish newspaper material provides a window into internationally circulated narratives portraying ultrasound as both a frightening and promising phenomenon. These ideas also constituted an important context for risk assessment during the early adoption and development of obstetrical ultrasound imaging, as shown by the case of Lund, Sweden, where the still-experimental technology was first imported from Scotland in the early 1960s. The article repositions ultrasound in the history of risk and risk management in modern societies and also sheds new light on the history of ultrasound visualization by situating it in a broader context of media culture.

Understanding Trust Determinants in a Live Chat Service on Familial Cancer: Qualitative Triangulation Study With Focus Groups and Interviews in Germany.

BACKGROUND: In dealing with familial cancer risk, seeking web-based health information can be a coping strategy for different stakeholder groups (ie, patients, relatives, and those suspecting an elevated familial cancer risk). In the vast digital landscape marked by a varied quality of web-based information and evolving technologies, trust emerges as a pivotal factor, guiding the process of health information seeking and interacting with digital health services. This trust formation in health information can be conceptualized as context dependent and multidimensional, involving 3 key dimensions: information seeker (trustor), information provider (trustee), and medium or platform (application). Owing to the rapid changes in the digital context, it is critical to understand how seekers form trust in new services, given the interplay among these different dimensions. An example of such a new service is a live chat operated by physicians for the general public with personalized cancer-related information and a focus on familial cancer risk. OBJECTIVE: To gain a comprehensive picture of trust formation in a cancer-related live chat service, this study investigates the 3 dimensions of trust-trustor, trustee, and application-and their respective relevant characteristics based on a model of trust in web-based health information. In addition, the study aims to compare these characteristics across the 3 different stakeholder groups, with the goal to enhance the service's trustworthiness for each group. METHODS: This qualitative study triangulated the different perspectives of medical cancer advisers, advisers from cancer support groups, and members of the public in interviews and focus group discussions to explore the 3 dimensions of trust-trustor, trustee, and application-and their determinants for a new live chat service for familial cancer risk to be implemented at the German Cancer Information Service. RESULTS: The results indicate that experience with familial cancer risk is the key trustor characteristic to using, and trusting information provided by, the live chat service. The live chat might also be particularly valuable for people from minority groups who have unmet needs from physician-patient interactions. Participants highlighted trustee characteristics such as ability, benevolence, integrity, and humanness (ie, not a chatbot) as pivotal in a trustworthy cancer live chat service. Application-related characteristics, including the reputation of the institution, user-centric design, modern technology, and visual appeal, were also deemed essential. Despite the different backgrounds and sociodemographics of the 3 stakeholder groups, many overlaps were found among the 3 trust dimensions and their respective characteristics. CONCLUSIONS: Trust in a live chat for cancer information is formed by different dimensions and characteristics of trust. This study underscores the importance of understanding trust formation in digital health services and suggests potential enhancements for effective, trustworthy interactions in live chat services (eg, by providing biographies of the human medical experts to differentiate them from artificial intelligence chatbots).

The novel dynamic MPFL-reconstruction technique: cheaper and better?

PURPOSE: Reconstruction of the medial patellofemoral ligament (MPFL) is an established procedure to restore patellar stability. Aim of this study is to evaluate the results of a dynamic MPFL reconstruction technique in a large university hospital setting. METHODS: Two hundred and thirteen consecutive patients with 221 knees were surgically treated for recurrent lateral patellar dislocation. All patients obtained dynamic reconstruction of the MPFL with detachment of the gracilis tendon at the pes anserinus while maintaining the proximal origin at the gracilis muscle. Patellar fixation was performed by oblique transpatellar tunnel transfer. Follow-up data including Kujala and BANFF score, pain level as well as recurrent patella instability were collected at a minimum follow-up of 2 years. RESULTS: Follow-up could be obtained from 158 patients (71%). The mean follow-up time was 5.4 years. Mean pain level was 1.9 ± 2.0 on the VAS. Mean Kujala score was 78.4 ± 15.5. Mean BANFF score was 62.4 ± 22.3. MPFL-reconstructions that were performed by surgeons with a routine of more than ten procedures had a significantly shorter surgical time 52.3 ± 17.6 min. Male patients yielded higher satisfaction rates and better clinical scores compared to females. Complications occurred in 27.2% of procedures, 20.9% requiring revision surgery of which were 9.5% related to recurrent patellar instability. 78% of all patients indicated they would undergo the procedure again. CONCLUSION: Dynamic MPFL reconstruction presents a reproducible procedure with increased complication rates, inferior to the results of static reconstruction described in the literature. Despite, it appears to be an efficient procedure to restore patellar stability in a large university hospital setting, without the necessity for intraoperative fluoroscopy. TRIAL REGISTRATION: The study was registered in ClinicalTrials.gov with the registration number NCT04438109 on June 18th 2020.

Primary antibody deficiency: The impact on the quality of life and mental health of affected children and their parents.

AIM: To evaluate health-related quality of life, mental health and treatment-related stress responses in children with primary antibody deficiency and both their parents. METHODS: Children and their parents completed the standardised questionnaires Pediatric Quality of life Inventory, Strength and Difficulties Questionnaire and Impact of Event Scale. Parents also completed standardised questionnaires regarding their own mental health and quality of life. The results were compared to those of healthy children, kidney transplanted children and children in remission from acute lymphoblastic leukaemia. RESULTS: Children with primary antibody deficiency reported a poorer health-related quality of life compared to healthy children and children in remission from acute lymphoblastic leukaemia. They reported poorer mental health compared with healthy children. Mothers of children with primary antibody deficiency reported poorer mental health compared to mothers of healthy children but comparable to mothers of chronically ill children. Parents reported a similar quality of life as the general Norwegian population. Treatment with subcutaneous immunoglobulin infusions at home is generally well tolerated, but some report severe treatment-related stress. CONCLUSION: Primary antibody deficiency has a significant impact on quality of life and mental health of affected children. Patients and parents with severe treatment-related stress should be identified and helped.

A suitable country: the relationship between Sweden's interwar population policy and family planning in postindependence India.

This article delineates a strong continuity, particularly in terms of personnel, between interwar domestic population policies and Sweden's postwar participation in international and transnational population-control programs. It argues that Swedish engagement in population control and family planning in the emerging Third World, and particularly in South Asia, was motivated by the conviction that poverty and underdevelopment must be attacked on several fronts simultaneously, with population control being one of the most important. In its first bilateral aid programs Sweden would prioritize the promotion of birth control primarily because it was still too controversial to be promoted multilaterally, not least for religious reasons; and because Swedish experts were regarded as especially liberal, rational, and secularized. Sterilization expertise played no decisive part in this continuity. When first establishing themselves in South Asia, Swedish experts would recommend the rhythm method and other contraceptive methods that depended on self-control.
