Our study aimed to report on variables associated with communicative health literacy (COM-HL) in European adults. The HLS survey was conducted in 2019-2021 including nine countries which measured COM-HL by using a validated questionnaire (HLS-COM-P-Q6 with a score ranging from 0 to 100). Linear regression models were used to study variables associated with COM-HL globally (multilevel model with random intercepts and slopes and at country level) and in each country.

Background: Psilocybin has been suggested as a novel, rapid-acting treatment for depression. Two consecutive doses have been shown to markedly decrease symptom severity in an open-label setting or when compared to a waiting list group. To date, to our knowledge, no other trial compared a single, moderate dose of psilocybin to a placebo condition.

Background: Sufficient communicative health literacy (COM-HL) is important for patients actively participating in dialogue with physicians, expressing their needs and desires for treatment, and asking clarifying questions. There is a lack of instruments combining communication and HL proficiency. Hence, the aim was to establish an instrument with sufficient psychometric properties for measuring COM-HL.

Article Synopsis
  • Patients find it hard to navigate complex health care systems, necessitating improved health literacy, specifically navigational health literacy (HL-NAV).
  • The Health Literacy Population Survey 2019 (HLS) aimed to create a measurement tool for HL-NAV, the HL-NAV-HLS19, through a collaborative process involving literature reviews and expert feedback.
  • The finalized instrument includes twelve items that will be tested in the HLS survey, offering data on HL-NAV across participating countries while suggesting further adaptations for broader use.

This report provides an overview of Austria's approaches to improve population health literacy (HL). The report suggests: a) research can trigger health policy responses to improve HL; b) linking HL improvement to other reform agendas can boost effectiveness, and c) coordination is required for continuously and systematically working towards better HL. Examples of strategic thematic approaches and interventions - especially in the fields of communication in healthcare, health information products, and organizational HL responsiveness - are provided, and Austria's role in preparing the next European HL survey, HLS19, is briefly described.

Objective: Present and discuss the development and basic structure of a multilevel approach to strengthen patient and family engaged care, "The New Haven Recommendations on partnering with patients, families and citizens to enhance performance and quality in health promoting hospitals and health services".

Methods: A generic literature review was conducted followed by a Delphi procedure to prepare the New Haven Recommendations. From systems theory perspective, three conceptual levels are used to map action areas to enhance patient and family engaged care.

Background And Purpose: To study the impact of coronal and sagittal views (CSV) on the gross tumor volume (GTV) delineation on CT and matched PET/CT scans in non-small cell lung cancer.

Material And Methods: GTV delineations were performed by 11 experienced radiation oncologists on CT and PET/CT in 22 patients. Two tumor groups were defined: Group I: Primary tumors surrounded by lung or visceral pleura, without venous invasion, and without large extensions to the chest wall or the mediastinum.

Purpose: Despite conventional radiation therapy, 54 Gy in single doses of 1.8 Gy (54/1.8 Gy) over 6 weeks, most children with diffuse intrinsic pontine glioma (DIPG) will die within 1 year after diagnosis.

Purpose: To determine local control, late toxicity and metastatic free survival (MFS) of patients treated with fractionated stereotactic radiation therapy (fSRT) for uveal melanoma (UM).

Methods And Materials: Between 1999 and 2007, 102 UM patients were included in a prospective study of a single institution (median follow-up (FU) 32 months; median tumor thickness 6 mm); five fractions of 10 Gy were given. Primary endpoints were local tumor control and late toxicity (including visual outcome and eye preservation).

Objective: To provide an overview of published data on user participation in Health Care.

Background: Active and passive involvement of consumers into agendas associated with Health Care is still an exception. Data on the success of user participation projects in various areas of Health Care are lacking.

Objective: There is a broad range qualitative linguistic research (sequential analysis) on doctor-patient interaction that had only a marginal impact on clinical research and practice. At least in parts this is due to the lack of qualitative research synthesis in the field. Available research summaries are not systematic in their methodology.

Purpose: To compare pathology macroscopic tumor dimensions with magnetic resonance imaging (MRI) measurements and to establish the microscopic tumor extension of colorectal liver metastases.

Methods And Materials: In a prospective pilot study we included patients with colorectal liver metastases planned for surgery and eligible for MRI. A liver MRI was performed within 48 hours before surgery.

Purpose: To validate and clinically evaluate autocontouring using atlas-based autosegmentation (ABAS) of computed tomography images.

Methods And Materials: The data from 10 head-and-neck patients were selected as input for ABAS, and neck levels I-V and 20 organs at risk were manually contoured according to published guidelines. The total contouring times were recorded.

The aim of the present study is to determine and compare initial treatment costs of microsurgery, linear accelerator (LINAC) radiosurgery, and gamma knife radiosurgery in meningioma patients. Additionally, the follow-up costs in the first year after initial treatment were assessed. Cost analyses were performed at two neurosurgical departments in The Netherlands from the healthcare providers' perspective.

Purpose: To determine the variation in target delineation of nasopharyngeal carcinoma and the impact of measures to minimize this variation.

Materials And Methods: For ten nasopharyngeal cancer patients, ten observers each delineated the Clinical Target Volume (CTV) and the CTV elective. After 3D analysis of the delineated volumes, a second delineation was performed.

Purpose: To assess day-to-day differences between planned and delivered target volume (TV) and organ-at-risk (OAR) dose distributions in liver stereotactic body radiation therapy (SBRT), and to investigate the dosimetric impact of setup corrections.

Methods And Materials: For 14 patients previously treated with SBRT, the planning CT scan and three treatment scans (one for each fraction) were included in this study. For each treatment scan, two dose distributions were calculated: one using the planned setup for the body frame (no correction), and one using the clinically applied (corrected) setup derived from measured tumor displacements.

Purpose: To find a dose-volume effect for inhomogeneous irradiated lacrimal glands.

Methods And Materials: Between 1999 and 2006, 72 patients (42 men and 30 women) were treated with fractionated stereotactic radiotherapy in a prospective, nonrandomized clinical trial (median follow-up, 32 months). A total dose of 50 Gy was given on 5 consecutive days.

Agricultural nonpoint source pollution remains a persistent environmental problem, despite the large amount of money that has been spent on its abatement. At local scales, agricultural best management practices (BMPs) have been shown to be effective at reducing nutrient and sediment inputs to surface waters. However, these effects have rarely been found to act in concert to produce measurable, broad-scale improvements in water quality.

Article Synopsis
  • - The study evaluates the effectiveness of stereotactic body radiation therapy (SBRT) for liver tumors, particularly its impact on patients' quality of life, marking the first report on this topic.
  • - Twenty-eight patients, deemed unsuitable for other treatments and with a strong performance status, were monitored and assessed for quality of life using multiple standardized questionnaires before and after SBRT.
  • - Results indicated that SBRT did not significantly affect the overall quality of life of patients, with some signs of improvement noted, suggesting the treatment is effective in local tumor control without compromising patient wellbeing.
