Background And Purpose: This study applied a modified version of the extended technology acceptance model (TAM2) to examine the factors determining the acceptance of health IT applications by caregivers in long-term care facilities. The antecedent variables, including social influence factors such as subjective norm and image were examined together with demographic variables including age, job level, long-term care work experience and computer skills in regard to their impact on caregivers' acceptance of health IT applications.
Methods: A self-administered questionnaire was developed based on the validated items from TAM2. The data was collected in a cross-sectional survey using convenience sample. Confirmatory factor analysis and structural equation modelling techniques were used to validate our causal model.
Results: Perceived usefulness, perceived ease of use and computer skills had significant positive impact, whereas image had significant negative impact on caregivers' intention to use health IT applications. Image, subjective norm and computer skills also indirectly impacted on intention through the mediating factor of ease of use. Ease of use, subjective norm and job level also determined perceived usefulness. The other demographic factors (including age and long-term care work experience) did not have any significant effect on caregivers' acceptance of a health IT application. Our model explains 34% of caregivers' intention to use an introduced IT application before any hands-on experience with the system established.
Conclusions: The planners and managers should ensure that a health IT application to be introduced into a long-term care facility is useful and easy to use. Effort should be focused on forming a positive social norm for the introduction of the new innovation and improving caregivers' computer skills. Securing the managers' and senior nurses' support for the innovation at the onset of the project is critical for success. Finally the caregivers appear to dislike the idea of increased IT ability will elevate their status.

Research has shown that physical activity on prescription (PAP), used in Swedish healthcare, increases patients' physical activity, but data are lacking regarding the long-term effects of PAP on exercise capacity. Therefor exercise capacity was evaluated in patients with metabolic risk factors, after 4.5 years of PAP treatment provided by physiotherapists in primary healthcare.

Early T-cell Precursor Acute Lymphoblastic Leukemia (ETP-ALL) is an immature subtype of T-cell acute lymphoblastic leukemia (T-ALL) commonly show deregulation of the LMO2-LYL1 stem cell transcription factors, activating mutations of cytokine receptor signaling, and poor early response to intensive chemotherapy. Previously, studies of the Lmo2 transgenic mouse model of ETP-ALL identified a population of stem-like T-cell progenitors with long-term self-renewal capacity and intrinsic chemotherapy resistance linked to cellular quiescence. Here, analyses of Lmo2 transgenic mice, patient-derived xenografts, and single-cell RNA-sequencing data from primary ETP-ALL identified a rare subpopulation of leukemic stem cells expressing high levels of the cytokine receptor FLT3.

Nowadays rice has become one of the world's staple foods. Rice in southern China is also a staple food for everyone, however, with the development of China's industrialization model, many industrial areas may be contaminated by heavy metals, leading to contamination of the agricultural areas. With the development of recent years, Nanning has become a heavily industrial development area, and rice is also a favourite staple food.

For individuals at high risk of developing breast cancer, interventions to mitigate this risk include surgical removal of their breasts and ovaries or five years treatment with the anti-estrogen tamoxifen or aromatase inhibitors. We hypothesized that a silicone based anti-estrogen-eluting implant placed within the breast would provide the risk reduction benefit of hormonal therapy, but without the adverse effects that limit compliance. To this end, we demonstrate that when placed adjacent to mammary tissue in the 7,12-dimethylbenz[a]anthracene-induced rat breast cancer model a fulvestrant-eluting implant delays breast cancer with minimal systemic exposure.

Background And Objective: Stress urinary incontinence (SUI), defined as any involuntary leakage of urine associated with physical activity, remains underdiagnosed and undertreated. This review aims to provide an updated overview of the prevalence, diagnosis, and treatment of SUI in women, drawing upon recent evidence-based literature and clinical guidelines.
Methods: A systematic search of the MEDLINE database was conducted to identify only the most up-to-date and relevant studies published up to February 26, 2024, including the reference ESTER systematic review.
