ABSTRACT

OBJECTIVES: This study aimed to investigate whether a significant trend regarding inpatient falls in Swiss acute care hospitals between 2011 and 2019 could be confirmed on a national level, and whether the trend persists after risk adjustment for patient-related fall risk factors.

DESIGN: A secondary data analysis was conducted based on annual multicentre cross-sectional studies carried out between 2011 and 2019.

SETTING: All Swiss acute care hospitals were obliged to participate in the surveys. Except for emergency departments, outpatient wards and recovery rooms, all wards were included.

PARTICIPANTS: All inpatients aged 18 or older who had given their informed consent and whose data were complete and available were included.

OUTCOME MEASURE: Whether a patient had fallen in the hospital was retrospectively determined on the survey day by asking patients the following question: Have you fallen in this institution in the last 30 days?

RESULTS: Based on data from 110 892 patients from 222 Swiss hospitals, a national inpatient fall rate of 3.7% was determined over the 9 survey years. A significant linear decreasing trend (p=0.004) was observed using the Cochran-Armitage trend test. After adjusting for patient-related fall risk factors in a two-level random intercept logistic regression model, a significant non-linear decreasing trend was found at the national level.

CONCLUSIONS: A significant decrease in fall rates in Swiss hospitals, indicating an improvement in the quality of care provided, could be confirmed both descriptively and after risk adjustment. However, the non-linear trend, that is, an initial decrease in inpatient falls that flattens out over time, also indicates a possible future increase in fall rates. Monitoring of falls in hospitals should be maintained at the national level. Risk adjustment accounts for the observed increase in patient-related fall risk factors in hospitals, thus promoting a fairer comparison of the quality of care provided over time.

ABSTRACT

OBJECTIVE: This study aimed to examine the mediation role of perceived social support in the relationship between functional limitations, depressive symptoms and quality of life among older people in Malaysia.

SETTING: The Malaysian National Health Morbidity Survey 2018: Elderly Health was a cross-sectional health community survey among adults aged 50 and above.

PARTICIPANTS: 3977 community-dwelling older Malaysians aged 60 and above.

OUTCOME MEASURES: Functional limitations were defined as personal activities of daily living (PADL) and instrumental activities of daily living (IADL), tested in separate paths in all analyses. PADL was measured using the Barthel Index, while IADL was measured using the Lawton and Brody scale. Perceived social support, depressive symptoms and quality of life were measured using the Duke Social Support Index, Geriatric Depression Scale-14 and Control, Autonomy, Self-Realisation and Pleasure-19 tools. We used mediation analysis through structural equation modelling to explore the role of perceived social support.

RESULTS: Perceived social support mediated the relationship between PADL and IADL with depressive symptoms, with the indirect effects at -0.079 and -0.103, respectively (p<0.001). Similarly, perceived social support mediated the relationship between PADL and IADL with quality of life, with the indirect effects at 0.238 and 0.301, respectively (p<0.001). We performed serial multiple mediation analysis and found that perceived social support and depressive symptoms mediated the path between PADL and IADL with quality of life, with the indirect effects at 0.598 and 0.747, respectively (p<0.001). The relationship between functional limitations and all outcomes remained significant in all mediation analyses.

CONCLUSION: The present study provides evidence that perceived social support relieves the influence of functional limitations on depressive symptoms and declining quality of life among older people. Therefore, it is imperative to establish a social support system to improve the overall well-being of older people.

ABSTRACT

INTRODUCTION: Upper limb (UL) dysfunctions are highly prevalent in people after breast cancer and have a great impact on performing activities in daily living. To improve care, a more comprehensive understanding of the development and persistence of UL dysfunctions is needed. Therefore, the UPLIFT-BC study will primarily examine the prognostic value of different factors at the body functions and structures, environmental and personal level of the International Classification of Functioning, Disability and Health (ICF) framework at 1-month post-surgery for persisting UL dysfunctions at 6 months after finishing cancer treatment.

METHODS AND ANALYSIS: A prospective longitudinal cohort study, running from 1-week pre-surgery to 6 months post-local cancer treatment, is performed in a cohort of 250 women diagnosed with primary breast cancer. Different potentially prognostic factors to UL dysfunctions, covering body functions and structures, environmental and personal factors of the ICF, are assessed pre-surgically and at different time points post-surgery. The primary aim is to investigate the prognostic value of these factors at 1-month post-surgery for subjective UL function (ie, QuickDASH) at 6 months post-cancer treatment, that is, 6 months post-radiotherapy or post-surgery (T3), depending on the individuals’ cancer treatment trajectory. In this, factors with relevant prognostic value pre-surgery are considered as well. Similar analyses are performed with an objective measure for UL function (ie, accelerometry) and a composite score of the combination of subjective and objective UL function. Second, in the subgroup of participants who receive radiotherapy, the prognostic value of the same factors is explored at 1-month post-radiotherapy and 6 months post-surgery. A forward stepwise selection strategy is used to obtain these multivariable prognostic models.

ETHICS AND DISSEMINATION: The study protocol was approved by the Ethics Committee of UZ/KU Leuven (reference number s66248). The results of this study will be published in peer-reviewed journals and will be presented at several research conferences.

ABSTRACT

BACKGROUND: The Rotterdam Eczema Study was an observational cohort study with an embedded pragmatic randomised controlled open-label trial. It was conducted in children with atopic dermatitis (AD) in the Dutch primary care system. The objective of the trial was to determine whether a potent topical corticosteroid (TCS) is more effective than a low-potency TCS.

OBJECTIVE: We are aiming to communicate transparently about the poor recruitment for the trial part and to explore the reasons why recruitment was weak.

DESIGN: We used a survey to find out what patients in the cohort did when they experienced a flare-up.

METHODS: Descriptive statistics were used to present the baseline characteristics of participants in the trial and the results of the survey.

RESULTS: In total, 367 patients were included in the cohort. Of these, 32 were randomly assigned to a trial treatment; they had a median age of 4.0 years (IQR 2.0-9.8). A total of 69 of the 86 children (80.2%) who could participate in the survey responded. 39 (56.5%) suffered a flare-up during the follow-up (making them potentially eligible for inclusion in the trial). 26 out of 39 (66.7%) increased their use of an emollient and/or TCS themselves. Only 12 of the 39 (30.7%) contacted their general practitioner (GP) as instructed in the study protocol, but 8 out of these 12 did not meet the inclusion criteria for the trial.

CONCLUSION: The main reason why cohort participants did not take part in the trial was that they did not contact their GPs when they experienced an AD flare-up. Furthermore, the majority of patients who contacted their GPs did not match the inclusion criteria of the trial. We expect that the lessons learnt from this study will be useful when developing future studies of children with AD in primary care.

ABSTRACT

Multidrug-resistant organism infections are a serious health problem globally, and can result in patient mortality and morbidity. In this descriptive study, we produced the first web application for transmission prevention specific to the situation based on nursing experience, knowledge, and practice guidelines and to evaluate web application satisfaction among Thai nurses. The sample comprised 282 Thai registered nurses experienced in caring for patients with multidrug-resistant organisms in a tertiary hospital. A demographic form and knowledge test were completed anonymously online. Data were analyzed using descriptive statistics. The application emphasized crucial topics for which participants had low preliminary knowledge and included tutorial sessions, pictures, video clips, drills, and a post-test. The application was piloted with a random sample of 30 nurses, and an instrument tested their satisfaction with this. Results revealed that preliminary knowledge scores for preventing transmission were moderate, and participants were highly satisfied with the application. Findings suggest the application is suitable for Thai nurses and could be applied to nursing practice elsewhere. However, further testing is recommended before implementing it into nursing practice.

ABSTRACT

OBJECTIVES: Autologous tendon cell implantation (OrthoATI™) therapy has demonstrated efficacy in treating patients with tendinopathy at various anatomical sites. This study evaluates the effect of patient age, gender and tendon biopsy site on morphology, growth and gene expression of autologous tendon cells used to treat chronic tendinopathy.

METHODS: Patients undergoing OrthoATI™ for tendinopathies between 2020 and 2022 were initially treated by biopsies taken from patella tendon (PT) or palmaris longus tendon (PL). Autologous tenocytes were treated at a Good Manufacturing Practice (GMP) cell laboratory where they were isolated, cultured and expanded for four to six weeks. Cell morphology was assessed using phase contrast microscopy. Droplet digital PCR (ddPCR) was utilised for gene expression analysis. Dichotomous results were compared between groups using x² or Fisher’s exact tests with no adjustment for multiple comparisons. The non-parametric Mann-Whitney U and Kruskal-Wallis tests were utilised for the sex and age (<35y, 35-44y, 45-54y, >55y) analyses respectively. All analyses were performed using IBM SPSS v27, and a two-tailed P-value of <0.05 was considered statistically significant.

RESULTS: 149 patients were included in the analysis. The PT was biopsied in 63 patients, and PL in 86 patients. There were no observer effects for age and gender between PT and PL groups. There was no statistical significance between the PT and PL tendons for cell morphology, average cell population doubling time (PDT) (PT 83.9 vs PL 82.7 hours, p=0.482), cellular yield (PT 16.2 vs PL 15.2×10⁶ , p=0.099), and cell viability (PT 98.7 vs PL 99.0%, p=0.277). Additionally, ddPCR analyses showed no statistical significance found in tenogenic gene expression including collagen type I (COL1, p=0.86), tenomodulin (TNMD, p=0.837) and scleraxis (SCX, p=0.331) between PT- and PL-derived tendon cells. An age stratification analysis found no effect on growth and gene expression. COL1 was found to be higher in males when compared to females (P<0.001), but otherwise no difference was seen in growth and gene expression in the gender analysis. No post-biopsy clinical complications were reported for either group.

CONCLUSION: This study has shown that the growth and bioactivities of tendon cells from tendon biopsies for OrthoATI™ are not affected by tendon donor site and age.

ABSTRACT

Although clinical trials have shown that denosumab significantly increases bone mineral density at key skeletal sites more than oral bisphosphonates, evidence is lacking from head-to-head randomized trials evaluating fracture outcomes. This retrospective cohort study uses administrative claims data from Medicare fee-for service beneficiaries to evaluate the comparative effectiveness of denosumab versus alendronate in reducing fracture risk among women with postmenopausal osteoporosis (PMO) in the US. Women with PMO ≥ 66 years of age with no prior history of osteoporosis treatment, who initiated denosumab (n = 89 115) or alendronate (n = 389 536) from 2012 to 2018, were followed from treatment initiation until the first of a specific fracture outcome, treatment discontinuation or switch, end of study (December 31, 2019), or other censoring criteria. A doubly robust inverse-probability of treatment and censoring weighted function was used to estimate the risk ratio associated with the use of denosumab compared with alendronate for hip, nonvertebral (NV; includes hip, humerus, pelvis, radius/ulna, other femur), non-hip nonvertebral (NHNV), hospitalized vertebral (HV), and major osteoporotic (MOP; consisting of NV and HV) fractures. Overall, denosumab reduced the risk of MOP by 39%, hip by 36%, NV by 43%, NHNV by 50%, and HV fractures by 30% compared with alendronate. Denosumab reduced the risk of MOP fractures by 9% at year 1, 12% at year 2, 18% at year 3, and 31% at year 5. An increase in the magnitude of fracture risk reduction with increasing duration of exposure was also observed for other NV fracture outcomes. In this cohort of almost half-a-million treatment-naive women with PMO, we observed clinically significant reductions in the risk of MOP, hip, NV, NHNV, and HV fractures for patients on denosumab compared with alendronate. Patients who remained on denosumab for longer periods of time experienced greater reductions in fracture risk.

ABSTRACT

Zoonotic disease dynamics in wildlife hosts are rarely quantified at macroecological scales due to the lack of systematic surveys. Non-human primates (NHPs) host Plasmodium knowlesi, a zoonotic malaria of public health concern and the main barrier to malaria elimination in Southeast Asia. Understanding of regional P. knowlesi infection dynamics in wildlife is limited. Here, we systematically assemble reports of NHP P. knowlesi and investigate geographic determinants of prevalence in reservoir species. Meta-analysis of 6322 NHPs from 148 sites reveals that prevalence is heterogeneous across Southeast Asia, with low overall prevalence and high estimates for Malaysian Borneo. We find that regions exhibiting higher prevalence in NHPs overlap with human infection hotspots. In wildlife and humans, parasite transmission is linked to land conversion and fragmentation. By assembling remote sensing data and fitting statistical models to prevalence at multiple spatial scales, we identify novel relationships between P. knowlesi in NHPs and forest fragmentation. This suggests that higher prevalence may be contingent on habitat complexity, which would begin to explain observed geographic variation in parasite burden. These findings address critical gaps in understanding regional P. knowlesi epidemiology and indicate that prevalence in simian reservoirs may be a key spatial driver of human spillover risk.

ABSTRACT

INTRODUCTION: Effective pain control is crucial in dental practice; thus, local anesthetic techniques have been extensively taught. The Halstead technique is the most commonly used inferior alveolar nerve block despite its relatively high failure rate. On the other hand, the Vazirani‒Akinosi technique (VAT) is less commonly taught. This study evaluated changes in final-year students’ perceptions of VAT after a period of active learning.

METHODS: This prospective randomized study was performed in 2022 and included fifth-year dental students (n = 91). The study group (n = 49) received practical VAT training during oral surgery internships, whereas the control group (n = 42) did not. A Likert-scale questionnaire assessed students’ perceptions, theoretical knowledge, and difficulty levels. An independent sample t-test was used for comparison and the statistical significance level was set at p < 0.05.

RESULTS: The survey response rate was 100%. Statistical analysis revealed significant differences between the groups for seven of the 12 questionnaire statements (p < 0.05). Overall, perception scores favored the study group, indicating a more positive response. The statements related to theoretical knowledge, except for one statement, showed no significant differences (p > 0.05).

CONCLUSION: Practical training significantly improved students’ perceptions of VAT, demonstrating the importance of active learning in dental education. Faculties should integrate active learning methods to enhance students’ clinical skills and prepare them for professional practice.

ABSTRACT

BACKGROUND: Digital interventions are gaining increasing interest due to their structured nature, ready availability, and self-administered capabilities. Perinatal women have expressed a desire for such interventions. In this regard, behavioral activation interventions may be particularly suitable for digital administration.

OBJECTIVE: This study aims to exploratorily investigate and compare the feasibility of the internet-based self-help guided versus unguided version of the Brief Behavioral Activation Treatment for Depression-Revised, an empirically supported in-person behavioral activation protocol, targeting pregnant women with subclinical depression symptoms. A user-centered design is used, whereby data are collected with the intent of evaluating how to adjust the intervention in line with pregnant women’s needs. Usability and user engagement were evaluated.

METHODS: A total of 11 Italian pregnant women with subclinical depressive symptoms based on the Patient Health Questionnaire-9 (scoring<15) participated in this study; of them, 6 (55%) women were randomly assigned to the guided group (age: mean 32.17, SD 4.36 years) and 5 (45%) to the unguided group (age: mean 31, SD 4.95 years). The Moodle platform was used to deliver the interventions in an e-learning format. It consisted of 6 core modules and 3 optional modules; the latter aimed at revising the content of the former. In the guided group, each woman had weekly chats with their assigned human guide to support them in the homework revisions. The intervention content included text, pictures, and videos. Semistructured interviews were conducted, and descriptive statistics were analyzed.

RESULTS: Collectively, the data suggest that the guided intervention was better accepted than the unguided one. However, the high rates of dropout (at T6: guided group: 3/6, 50%; unguided: 4/5, 80%) suggest that a digital replica of Behavioral Activation Treatment for Depression-Revised may not be feasible in an e-learning format. The reduced usability of the platform used was reported, and homework was perceived as too time-consuming and effort-intensive. Moreover, the 6 core modules were deemed sufficient for the intervention’s goals, suggesting that the 3 optional modules could be eliminated. Nevertheless, participants from both groups expressed satisfaction with the content and found it relevant to their pregnancy experiences.

CONCLUSIONS: Overall, the findings have emphasized both the intervention’s merits and shortcomings. Results highlight the unsuitability of replicating an in-person protocol digitally as well as of the use of nonprofessional tools for the implementation of self-help interventions, ultimately making the intervention not feasible. Pregnant women have nonetheless expressed a desire to receive psychological support and commented on the possibilities of digital psychosocial supports, particularly those that are app-based. The information collected and the issues identified here are important to guide the development and co-design of a more refined platform for the intervention deployment and to tailor the intervention’s content to pregnant women’s needs.
