    The objective of this study was to analyse cervical range of motion, assessed over time by means of a digital inclinometer (EDI-320) and a three-dimensional electromagnetic tracking device (Flock of Birds). The maximum active cervical range of motion was assessed with two measurement devices in three sessions over time, with 6-week intervals. In total, 26 women and 24 men (mean age: 44.4, SD: 9.9) without known pathology of the cervical spine participated. Four movements were measured axial rotation with the cervical spine in a flexed and in an extended position, flexion-extension, and lateral bending. The results showed that the factor time was significant for rotation in extension and rotation in flexion. The factor device was significant for all movements measured. and the interaction term between time and device was significant for all movements except rotation in extension. The Flock of Birds measured significantly higher ranges of motion on all motions except for lateral bending. A substantial variation in cervical range of motion was observed over time (ranging from -5.6 to 8.1) as well as between devices (ranging from - 13.1 to 29.9). Substantial and significant differences in cervical range of motion were found over time as well as differences between the Flock of Birds and the EDI-320. (C) 2007 Elsevier Ltd. All rights reserved

    Background: Medication self-management is complicated for older people. Little is known about older persons’ considerations and decisions concerning medication therapy at home. Objective: (s): To explore how older people living at home self-manage their medication and what considerations and decisions underpin their medication self-management behavior. Methods: Semi-structured interviews with consenting participants (living at home, aged ≥65, ≥5 different prescription medications daily) were recorded and transcribed with supporting photographs. Content was analyzed with a directed approach and presented according to three phases of medication self-management (initiation, execution, and discontinuation). Results: Sixty people were interviewed. In the initiation phase, participants used different techniques to inform healthcare professionals and to fill and check prescriptions. Over-the-counter medication was seldom discussed, and potential interactions were unknown to the participants. Some participants decided to not start treatment after reading the patient information leaflets for fear of side effects. In the execution phase, participants had various methods for integrating the use of new and chronic medication in daily life. Usage problems were discussed with healthcare professionals, but side effects were not discussed, since the participants were not aware that the signs and symptoms of side effects could be medication-related. Furthermore, participants stored medication in various (sometimes incorrect) ways and devised their own systems for ordering and filling repeat prescriptions. In the discontinuation phase, some participants decided to stop or change doses by themselves (because of side effects, therapeutic effects, or a lack of effect). They also mentioned different considerations regarding medication disposal and disposed their medication (in)correctly, stored it for future use, or distributed it to others. Conclusions: Participants’ considerations and decisions led to the following: problems in organizing medication intake, inadequate discussion of medication-related information with healthcare professionals, and incorrect and undesirable medication storage and disposal. There is a need for medication self-management observation, monitoring, and assistance by healthcare professionals

    Home care nurses’ perceptions about their role in interprofessional collaborative practice in clinical medication reviews

    Regular clinical medication reviews (CMRs) are recommended for monitoring and addressing potential drug-related problems, especially in elderly people. Interprofessional collaborative practice (ICP) by general practitioners, community pharmacists, and nurses in a CMR is recommended and expected to produce more efficient CMRs. Involving home care nurses in ICP is not yet well implemented, and their perspectives are unclear. This study explores how they perceive their role in ICP in CMRs and the requirements to assume that role. Structured interviews were performed, using case-vignettes; data were analyzed with a thematic analysis approach. Twelve home care nurses were interviewed. Three themes regarding the nurses' role were identified: (1) observing, recognizing, and communicating information for a CMR to prescribers and community pharmacists (2); helping to provide patient information and education about implemented changes in the pharmaceutical care plan; and (3) the nurses’ level of involvement in ICP. Three themes regarding requirements were identified: (1) nursing competences, (2) periodic interprofessional consultation and ad hoc interprofessional communication, and (3) guidelines describing the role of nurses. Home care nurses could provide additional support in a CMR. Nursing competences, periodic interprofessional consultation and ad hoc interprofessional communication, and guidelines describing the role of home care nurses are required

    HIF1α-Dependent Induction of TFRC by a Combination of Intestinal Inflammation and Systemic Iron Deficiency in Inflammatory Bowel Disease

    Background and Aims: Iron deficiency (ID) is a frequent extra-intestinal manifestation in patients with Inflammatory Bowel Disease (IBD), who often do not respond to iron supplementation. Iron is a cofactor for hydroxylases that suppress the hypoxia-inducible factor-1α (HIF1α), a transcription factor regulating iron homeostasis. We hypothesized that iron deficiency affects mucosal HIF1α activity in IBD. Methods: IBD patients (n = 101) were subdivided based on iron status (ferritin levels or transferrin saturation) and systemic inflammation (C-reactive protein levels). 154 corresponding ileal and colonic biopsies were analyzed for differential expression of 20 HIF1α pathway-associated genes and related to iron and inflammation status. In vitro expression of selected HIF1α pathway genes were analyzed in wild-type and HIF1A-null Caco-2 cells. Results: Gene expression of the mucosal HIF1α pathway was most affected by intestinal location and inflammatory status. Especially, ileal mucosal TFRC expression, encoding the transferrin receptor TFR1, was increased in inflamed tissue (p < 0.001), and further enhanced in ID. Accordingly, TFRC expression in inflamed tissue associated negatively with serum iron levels, which was not observed in the non-inflamed mucosa. The HIF1α pathway agonist DMOG increased TFRC expression in Caco-2 cells, which was blunted in HIF1A-null cells. Conclusion: We demonstrate that inflammation and anatomical location primarily determine HIF1α pathway activation and downstream TFRC expression in the intestinal mucosa. IBD patients with ID may benefit from treatment with HIF1α-agonists by 1) increasing TFRC-mediated iron absorption in non-inflamed tissue and 2) decreasing mucosal inflammation, thereby improving their responsiveness to oral iron supplementation

    Integrating Top-down and Bottom-up Requirements in eHealth Development:The Case of a Mobile Self-compassion Intervention for People with Newly Diagnosed Cancer

    Get PDF
    Background: Psychosocial eHealth interventions for people with cancer are promising in reducing distress; however, their results in terms of effects and adherence rates are quite mixed. Developing interventions with a solid evidence base while still ensuring adaptation to user wishes and needs is recommended to overcome this. As most models of eHealth development are based primarily on examining user experiences (so-called bottom-up requirements), it is not clear how theory and evidence (so-called top-down requirements) may best be integrated into the development process. Objective: This study aims to investigate the integration of top-down and bottom-up requirements in the co-design of eHealth applications by building on the development of a mobile self-compassion intervention for people with newly diagnosed cancer. Methods: Four co-design tasks were formulated at the start of the project and adjusted and evaluated throughout: explore bottom-up experiences, reassess top-down content, incorporate bottom-up and top-down input into concrete features and design, and synergize bottom-up and top-down input into the intervention context. These tasks were executed iteratively during a series of co-design sessions over the course of 2 years, in which 15 people with cancer and 7 nurses (recruited from 2 hospitals) participated. On the basis of the sessions, a list of requirements, a final intervention design, and an evaluation of the co-design process and tasks were yielded. Results: The final list of requirements included intervention content (eg, major topics of compassionate mind training such as psychoeducation about 3 emotion systems and main issues that people with cancer encounter after diagnosis such as regulating information consumption), navigation, visual design, implementation strategies, and persuasive elements. The final intervention, Compas-Y, is a mobile self-compassion training comprising 6 training modules and several supportive functionalities such as a mood tracker and persuasive elements such as push notifications. The 4 co-design tasks helped overcome challenges in the development process such as dealing with conflicting top-down and bottom-up requirements and enabled the integration of all main requirements into the design. Conclusions: This study addressed the necessary integration of top-down and bottom-up requirements into eHealth development by examining a preliminary model of 4 co-design tasks. Broader considerations regarding the design of a mobile intervention based on traditional intervention formats and merging the scientific disciplines of psychology and design research are discussed

    Ninety-day complication rate based on 532 Latarjet procedures in Dutch hospitals with different operation volumes

    Get PDF
    Background: In this study, we aimed to provide insight into the 90-day complication rates following the Latarjet procedure. Data from 2015 were collected from multiple hospitals in the Netherlands, with different volumes of Latarjet procedures. Our second aim was to examine which patient and surgical factors were associated with complications.Methods: We conducted a retrospective chart review of 13 hospitals between 2015 and 2022. Data regarding complications within 90 days of Latarjet procedures were extracted. The effect of sex, age, body mass index (BMI), smoking, previous shoulder operations, fixation material, hospital volume, screw size, and operation time on the complication rate was assessed by multivariable logistic regression analysis.Results: Of the 532 included patients, 58 (10.9%) had complications. The most common complications were material failure (n = 19, 3.6%) and nerve injury (n = 13, 2.4%). The risk of complications was lower for male patients than for female patients (odds ratio, 0.40; 95% confidence interval, 0.21-0.77; P = .006). Age, BMI, smoking, previous shoulder operations, type of fixation material, hospital volume, screw size, and operation time were not associated with complications.Conclusion: The 90-day complication rate after the Latarjet procedure was 10.9% and was higher in female patients than in male patients. Age, BMI, smoking, previous shoulder operations, type of fixation material, hospital volume, screw size, and operation time did not affect complication rates. We advise setting up a national registry to prevent under-reporting of complications.</p
