Implications for Precision Accelerated Clinically Embedded Research (PACER): A novel technology-enabled approach to conducting minimal-risk research in outpatient community healthcare settings
Current challenges in the clinical research landscape include insufficient enrollment of study participants, lack of study participant diversity, protracted study progression, and the siloing of research within academic medical centers. Recent advances in technology could minimize barriers to producing effective, timely, and comprehensive clinical research by addressing issues from study design to dissemination of results. Particularly, the Fast Health Interoperability Resources standards and Clinical Decision Support Hooks could support data acquisition, sharing, and expansion of research across organizations and disparate electronic health records. We developed a novel approach, Precision Accelerated Clinically Embedded Research (PACER), that leverages these advances in healthcare technology to integrate very short, minimal-risk research activities into clinical encounters. PACER could enable scalable, efficient, and cost-effective clinical research and has enormous potential. However, PACER also presents potential ethical, sociotechnical, and implementation quandaries. The current study aimed to obtain insights on these matters from relevant individuals. We conducted 47 qualitative semi-structured interviews with patients, clinicians, research experts (individuals involved in developing and conducting research), and bioethicists. We sought participants’ perspectives on the potential ethical, sociotechnical, and implementation issues raised by PACER. We identified five key domains: impacts on clinical research, consent, compensation, impacts on people and organizations, and implementation. We examined interview participants’ views using bioethical principles of autonomy, justice/fairness, beneficence, and nonmaleficence. While participants had diverse views, these insights highlight important considerations for PACER implementation and suggest areas for future empirical work.

Behavioral determinants for glycemic control among type 2 diabetic patients in Hosanna town; institution based unmatched case control study
Backgrounds Together with other non-communicable diseases, diabetes mellitus (DM) remains main health threats to human beings throughout the world. Despite an alarming increment of its trend in Ethiopia, majority of diabetic patients failed to attain glycemic control. Thus, this study aimed at identifying modifiable lifestyles for glycemic control among patients with type 2 diabetic mellitus. Objectives To assess behavioral determinants of glycemic control among type 2 diabetic patients attending Wachemo University Nigist Eleni Mohammed Memorial Teaching Hospital (WUNEMMTH) in Hosanna, Ethiopia. Methods Institution based unmatched case control study was conducted from May15-July 15, 2023. The questionnaire was digitalized to open data kit (ODK) for android version. Data was collected by simple random sampling technique and analyzed using SPSS version 23. Descriptive and logistic regression analysis were performed. Adjusted odds ratios and 95% confidence intervals were used to measure the effect size. Level of statistical significance was declared at a p-value of < 0.05. Results From 232 expectants, 226 (cases = 113 and controls = 113) were participated, making the response rate 97.41%. After adjusting for others, non-adherence to fruit and vegetable intake (AOR = 3.38, 95% CI = 1.73-6.60), non-adherence to physical exercise (AOR = 4.94, 95% CI = 2.38-10.27), poor diabetic self-efficacy (AOR = 5.51, 95% CI = 2.85-10.66) and high body mass index (AOR = 3.68, 95% CI = 1.73-7.82) were independent determinants for poor glycemic control among T2DM clients. Conclusion and recommendations Self-efficacy and healthy lifestyle were behavioral determinants for glycemic control among T2DM patients. Thus, interventions targeting modifiable lifestyle should be an integral part of the management along with standard pharmacotherapy.

Hyperspectral target detection based on graph sampling and aggregation network
To comprehensively utilize the spectral information encapsulated within hyperspectral images and more effectively handle the intricate and irregular structures among pixels in complex hyperspectral data, a novel graph sampling aggregation network model is put forward for hyperspectral target detection. Notably, before this study, graph sampling aggregation networks had scarcely been employed in the realm of hyperspectral target detection. This proposed model is capable of autonomously learning the effective feature representations of nodes within the graph, thereby facilitating the extraction and processing of graph data. It achieves this by extracting feature vectors through principal component analysis to construct adjacency matrices and performing convolution operations on hyperspectral images via sparse matrix multiplication, which enables the propagation and aggregation of node features within the graph structure. Upon reconstructing the image, the target data is extracted using residuals, and target detection is accomplished by minimizing the constraint energy. The model was evaluated on seven hyperspectral image datasets, and the experimental results demonstrated that the proposed graph sampling aggregation network model could proficiently detect targets with an average detection accuracy exceeding 99 . 8%, outperforming other comparative models. Concurrently, it exhibits a remarkable adaptability to the diverse characteristics of different datasets, thus validating its high level of accuracy and robustness.

Comparison of the surgical efficacy of total hip replacement versus hemiarthroplasty in the treatment of femoral neck fractures in elderly patients with sarcopenia
Background Total hip arthroplasty (THA) and hemiarthroplasty (HA) are common surgical procedures for femoral neck fracture (FNF) in elderly patients; however, optimal treatment options remain controversial. Currently, limited research has compared the effectiveness of THA versus HA, specifically in patients with FNF and sarcopenia. Methods This retrospective study included data from 109 patients who fulfilled the inclusion criteria for the period between January 2015 and December 2017. Among these, 48 underwent THA, and 61 underwent hip arthroplasty (HA). The cross-sectional area (cm2) of muscle tissue at the pedicle level of the 12th thoracic vertebra (T12) was measured using chest computed tomography. The skeletal muscle index (SMI) was calculated by dividing the cross-sectional area of the muscle at the T12 pedicle by height squared. Sarcopenia was diagnosed when grip strength and SMI values were below the diagnostic cut-off value. Various factors were compared, including age, sex, SMI, body mass index (BMI), perioperative surgery-related indicators, postoperative 5-year survival, satisfaction, complication, and re-revision surgery rates between the 2 groups. Results There were no statistically significant differences between the THA and HA groups in terms of age (P = 0.227), sex (P = 0.870), SMI (P = 0.946), BMI (P = 0.310), postoperative time to ambulation (P = 0.803), length of hospitalization (P = 0.777), postoperative visual analog scale score (P = 0.933), and postoperative Harris score (P = 0.379). At the 5-year follow-up, there were no statistical differences in patient survival rate (P = 0.896), satisfaction (P = 0.945), incidence of complications (P = 0.796), or re-revision rate (P = 0.807). Patients who underwent THA had significantly longer operative times (P = 0.000) and larger surgical incisions (P = 0.000). They also experienced greater blood loss (P = 0.000) and blood transfusion volumes (P = 0.017), as well as increased hemoglobin (P = 0.000) and albumin (P = 0.000) loss. Furthermore, patients who underwent THA incurred higher surgical costs (P = 0.000). Conclusion THA and HA demonstrated comparable effectiveness and outcomes in patients with FNF and sarcopenia. HA was a less invasive and more cost-effective surgical option, making it the preferred choice.

The Inflammatory Bowel Disease Knowledge Inventory Device 2 (IBD-KID2) is an effective tool for measuring disease-specific knowledge in Chinese patients
Background The Inflammatory Bowel Disease Knowledge Inventory Device 2 (IBD-KID2) is a specialized tool designed to evaluate disease-specific knowledge in patients with inflammatory bowel disease. The aim of this study was to develop a Chinese version of IBD-KID2 and to test the reliability and validity of this tool in Chinese patients with IBD. Methods A Chinese version of IBD-KID2 was developed through initial cultural relevance/comprehension review and adaptation using content validity index for individual items (I-CVI, level > 0.78 acceptable) and the scale overall (S-CVI, level > 0.8 acceptable). A standardized approach was used to translate IBD-KID2 to Chinese, with the final tool being 15 items long and scored as one point for each correct answer (maximum score of 15). Tool validity was evaluated in a convenience sample of patients with IBD. External reliability was evaluated using test-retest analysis in a participant subset two weeks after baseline completion and internal reliability evaluated using cohort scores (Cronbach’s alpha, Cronbach’s α). Results Following expert review for cultural relevance/comprehension the original IBD-KID2 scored > 0.78 I-CVI and > 0.9 for the S-CVI, and the tool was then translated. Ninety-six participants with IBD completed the Chinese IBD-KID2; 68 (71%) were male, eight (8%) aged < 18 years, and 63 (66%) had Crohn’s disease. The mean IBD-KID2 score of the cohort was 9.2 (±3.2, range 3-14). Scores decreased with age (p = 0.012) and increased with higher levels of education (p < 0.001). The retest reliability in a subset of 30 patients showed a correlation of 0.89 (P < 0.001), with no difference between the two time points (mean difference 0.4, = 0.16). The tool had high internal consistency with a Cronbach’s α coefficient of 0.8. Conclusion The Chinese version of the IBD-KID2 demonstrated satisfactory reliability and validity, making it a robust instrument for evaluating disease-specific knowledge in individuals with IBD.
