Impact of Precision in Staging Acute Kidney Injury and Chronic Kidney Disease on Treatment Outcomes: An Observational Study

(1) Background: “Kidney Disease: Improving Global Outcomes” (KDIGO) provides guidelines for identifying the stages of acute kidney injury (AKI) and chronic kidney disease (CKD). A data-driven rule-based engine was developed to determine KDIGO staging compared to KD-related keywords in discharge letters. (2) Methods: To assess potential differences in outcomes, we compare the patient subgroups with exact KDIGO staging to imprecise or missing staging for all-cause mortality, in-hospital mortality, selection bias and costs by applying Kaplan–Meier analysis and the Cox proportional hazards regression model. We analysed 63,105 in-patient cases from 2016 to 2023 at a tertiary hospital with AKI, CKD and acute-on-chronic KD. (3) Results: Imprecise and missing CKD staging were associated with an 85% higher risk of all-cause and in-hospital mortality (CI: 1.7 to 2.0 and 1.66 to 2.03, respectively) compared to exact staging for any given disease status; imprecise or missing AKI staging increased in-hospital mortality risk by 56% and 57% (CI: 1.43 to 1.70 and 1.37 to 1.81, respectively) in patients with AKI. (4) Conclusions: Exact staging is associated with better outcomes in KD management. Our study provides valuable insight into potential quality and outcome improvements and lower costs, considering elderly patients, women and patients with acute-on-chronic KD as the most vulnerable.

Nudge theories and strategies influencing adult health behaviors and outcomes in COPD management: a systematic review

ObjectiveChronic obstructive pulmonary disease (COPD) is a chronic respiratory disease with high prevalence and mortality, and self-management is a key component for better outcomes of COPD. Recently, nudging has shown promising potential in COPD management. In the present study, we conducted a systematic review to collate the list of nudges and identified the variables that influence nudging.MethodsWe undertook a systematic review. We employed database searches and snowballing. Data from selected studies were extracted. The risk of bias was assessed using the Cochrane Effective Practice and Organization of Care risk of bias tool. The study is registered with PROSPERO, CRD42023427051.ResultsWe retrieved 4,022 studies from database searches and 38 studies were included. By snowballing, 5 additional studies were obtained. Nudges were classified into four types: social influence, gamification, reminder, and feedback. Medication adherence, inhalation technique, physical activity, smoking cessation, vaccination administration, exercise capacity, self-efficacy, pulmonary function, clinical symptoms, and quality of life were analyzed as targeted health behaviors and outcomes. We found medication adherence was significantly improved by reminders via mobile applications or text materials, as well as feedback based on devices. Additionally, reminders through text materials greatly enhance inhalation techniques and vaccination in patients.ConclusionThis review demonstrates nudging can improve the health behaviors of patients with COPD and shows great potential for certain outcomes, particularly medication adherence, inhalation techniques, and vaccination. Additionally, the delivery modes, the patient characteristics, and the durations and seasons of interventions may influence the successful nudge-based intervention.Clinical trial registrationThis review has been registered in the international Prospective Registry of Systematic Evaluation (PROSPERO) database (identifier number CRD42023427051).

Multifunctional SEBS/AgNWs Nanocomposite Films with Antimicrobial, Antioxidant, and Anti-Inflammatory Properties Promote Infected Wound Healing.

Wound healing is a complex biological process that can trigger inflammation and oxidative stress and impair myofibrillogenesis and angiogenesis. Several advanced wound-dressing nanocomposite materials have been designed to address these issues. Here, we designed a new multifunctional styrene-ethylene-butylene-styrene/silver nanowire (SEBS/AgNWs)-based nanocomposite film with antimicrobial, antioxidant, and anti-inflammatory properties to promote wound healing. The porous morphological structure of SEBS/AgNWs enhances their antimicrobial, antioxidant, and anti-inflammatory properties. SEBS/AgNWs significantly inhibited the growth of Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Escherichia coli strains, effectively wiping out ABTS•+, DPPH•, hydrogen peroxide (H2O2), and hydroxyl (•OH) radicals, showing their effective ROS-scavenging properties. It further showed significant antioxidant properties by increasing the levels of enzyme-like catalase (CAT), superoxide dismutase (SOD), and glutathione (GSH), while decreasing malonaldehyde (MDA) levels. Additionally, SEBS/AgNWs reduced the expression of interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α), while increasing levels of transforming growth factor- β (TGF-β), vascular endothelial growth factor-A (VEGF), and CD31 in wound healing. This suggests that applying a multifunctional nanoplatform based on SEBS/AgNWs could enhance wound healing and improve patient outcomes in wound care management.

Sustainable Drivers of Financial Success in Nigeria’s Non-Financial Sector: A Managerial Perspective

This study examines the determinants of financial performance from a managerial perspective capturing managerial outcomes such as managerial hubris, meetings, risk and compensation. This study utilises the ex post facto methodology. Using a panel ordinary least square regression, the findings demonstrate that a higher frequency of board meetings has a detrimental effect on financial performance, resulting in a 3% decline for each additional meeting. This is a result of an abundance of meetings, mental exhaustion from making too many decisions, and excessive control over tasks and processes. Managerial remuneration has a negative influence on financial performance, resulting in a 21% decline for each unit increase. Nevertheless, despite a substantial 83% decline in performance, management hubris does not have a meaningful impact on financial outcomes. Finally, exercising careful and wise decision-making while taking risks promotes the development of new ideas and the capacity to adjust to new circumstances, resulting in a significant 29% growth. The study's findings indicate that implementing strategic risk management may improve financial performance. This suggests that pay should be in line with long-term goals and that fostering a culture of transparent communication and efficient governance is crucial for minimising adverse effects and fostering sustainable growth outcomes.

The DAIR-procedure in fracture-related infection–When and how

This narrative review discusses treatment strategies and key considerations guiding decisions in the surgical management of fracture-related infections (FRI). Treatment options primarily revolve around two approaches: debridement antibiotics and implant retention (DAIR), or implant exchange, either in a one or multiple-stage strategy. Several considerations, including time since infection onset, implant type, stability, causative pathogens, host physiology, and soft tissue conditions, inform the choice of surgical intervention for FRI. Current literature supports the preference for a DAIR approach in cases with a short duration of ongoing symptoms, a stable implant with satisfactory fracture reduction, and a viable soft tissue envelope. Conversely, one- or multiple-stage implant exchange is deemed beneficial in instances of compromised local and systemic host physiology, mature biofilm, difficult-to-treat pathogens, intramedullary implants, and cases involving reinfections or failed DAIR procedures. Notably, these recommendations draw parallels from periprosthetic joint infection treatment strategies, constrained by the limited availability of randomized controlled trials comparing these options specifically in acute FRI. In conclusion, future perspectives call for extensive investigations into biofilm maturation and the impact of time on treatment outcomes. Additionally, there is a need for a standardized classification system for FRI to enhance the comparability of treatment outcomes in FRI management.

Endoscopic Sinus Surgery for Chronic Rhino Sinusitis with Nasal Polyps: Predictive Factors of Recurrence.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammatory condition which may have a significant impact on quality of life. Endoscopic sinus surgery (ESS) is usually indicated for patients' refractory to maximal medical treatment and presents high recurrence and revision surgery rates. Objective: The aims of this study are to evaluate ESS outcome in CRSwNP management and to assess independent predictive factors for recurrence. Methods: Retrospective medical chart review of patients who underwent ESS for recalcitrant CRSwNP, from January 2002 to December 2021, with a minimum follow-up time of 12 months. Results: This study enrolled 280 patients; 52.5% of whom were males, with a mean age of 41.44 ± 14.25 years. Asthma was the most common comorbidity (36.4%, n = 102) and aspirin exacerbated respiratory disease was present in 16.8% (n = 47) of the study population. We found a recurrence rate of 20.7% (n = 58) and 8.9% (n = 25) of patients required revision surgery. Multivariate analysis identified as independent variables of recurrence (95% CI): no compliance with medication after surgery using topical steroids (OR = 16.056; CI 7.887-32.684; P < .001). Conclusions: ESS proved to be an effective treatment in CRSwNP but with a considerable rate of recurrence. These results indicated an important correlation of postoperative topical steroids compliance with disease recurrence.

Evaluation of drug use in stroke patients at the inpatient unit of Brebes Hospital, Central Java

Background: Effective stroke treatment is complicated by factors such as polypharmacy, drug interactions, and side effects, leading to drug-related problems (DRPs) that hinder therapeutic outcomes. Evaluating drug use in stroke patients is crucial to ensure rational, safe, effective, and efficient treatment, ultimately improving therapeutic outcomes. Objective: This study aimed to evaluate the drug use patterns in inpatient stroke patients at Brebes Hospital, focusing on the appropriateness of drug selection, dosage, administration, and the impact of patient characteristics on DRPs. Method: A retrospective, descriptive evaluative design was employed, with data collected from medical records of stroke patients hospitalized at Brebes Hospital between May and July 2022. A total of 135 patients (110 ischemic, 25 hemorrhagic stroke) were included through consecutive sampling. Univariate analysis was used to describe patient characteristics and treatment patterns, while bivariate analysis with the chi-square test assessed the relationship between patient characteristics and DRPs. Results: The most common medications included citicoline (88.15%), clopidogrel (68.85%), and amlodipine (40.48%). DRPs were identified, including non-compliance with guidelines (1 case), contraindicated drugs (5 cases), and inappropriate drug selection (1 case). Notably, five cases of contraindicated use of omeprazole with clopidogrel and one case of phenytoin without indication were observed. Patient characteristics such as age and comorbidities did not significantly influence the incidence of DRPs (p &gt; 0.05). Conclusion: The study found irrational drug use in stroke patients, with DRPs posing challenges for treatment optimization. Addressing DRPs through improved prescribing practices and pharmacist intervention is crucial to enhancing therapeutic outcomes in stroke management.

Disparities in management of symptomatic osteoporotic vertebral compression fractures: a nationwide multidisciplinary survey

SummaryThis nationwide multidisciplinary survey found dissatisfaction among physicians with current osteoporotic vertebral compression fracture care, revealing significant disparities in diagnosis, treatment, and follow-up practices. Issues include poor communication and differing guidelines. Improving interdisciplinary collaboration and standardized care strategies is essential for better patient outcomes.PurposeThis survey aims to assess current preferred care practices for symptomatic osteoporotic vertebral compression fractures (OVCF) in the Netherlands, focusing on guideline adherence, identifying knowledge gaps, and clarifying consensus and collaboration across medical disciplines in OVCF treatment.MethodsThis cross-sectional study was conducted via Qualtrics (Provo, UT) using a self-administered online survey distributed to 238 general practitioners and physicians in orthopedics, traumatology, internal medicine, rheumatology, and geriatrics working at 51 hospitals in the Netherlands. The survey, conducted in Dutch, included 36 multiple-choice and two open questions and was accessible via an anonymous email link or QR code. General practitioners received additional questions specific to their role. Data was anonymized, stored securely, and analyzed using descriptive statistics in Microsoft Excel and SPSS (Version 24). Open-ended responses were coded and categorized. The survey was conducted prior to the publication of the updated Federation of Medical Specialists guidelines in 2024.ResultsPhysicians across various disciplines uniformly expressed dissatisfaction with current OVCF care. The survey highlighted significant disparities in diagnosis, treatment, and follow-up practices. A lack of communication between primary and secondary care providers and differing guidelines further complicate OVCF management. These issues point to considerable variation in clinical practice and gaps in interdisciplinary collaboration.ConclusionAddressing the identified issues requires fostering interdisciplinary collaboration and creating cohesive care strategies. Ensuring access to diagnostic resources in both primary and secondary care and establishing coordinated care models promises more structured and standardized treatment. These steps are crucial for enhancing patient outcomes in OVCF management.

Ultrasound visualization of Botulinum toxin injection: Identifying clinical correlates to optimize outcomes in spasticity management.

Botulinum toxin injections are well established and commonly used for spasticity management. Clinicians strive to optimize outcomes from toxin injections. One potential complication is toxin spread beyond the intended muscle, which can lead to unwanted weakness. The utilization of ultrasound allows direct visualization of target muscles and identification of toxin leakage from the target muscle. Ultrasound evaluation of clinical factors that correlate to toxin leakage have not been studied. To identify cases of botulinum toxin injectate leak beyond the targeted muscle during ultrasound-guided spasticity injections and associate cases of leak with predictive clinical factors, which include muscle size, fibroadipose changes, and number of previous injections. This was a prospective observational study. An outpatient clinic in an academic medical center. Patients who demonstrated wrist flexor spasticity warranting intervention were invited to participate. Patients received standard-of-care spasticity management with injection of onabotulinumtoxinA into the flexor carpi radialis muscle based upon clinical presentation and prescribing guidelines. Ultrasound video was recorded, and a blinded review was conducted by the study team. The primary outcome measure was visualized leak of injectate on recorded ultrasound video. Documented leak was then associated with clinical factors including diameter of the flexor carpi radialis, volume of injectate used, history of prior injections, and fibrotic change of the muscle. The study included 54 patients, 77.8% of whom had an underlying diagnosis of cerebrovascular accident. Injectate leak was observed in 18.5% of injections and could not be confirmed in 9.3% of injections. Multivariable analysis demonstrated increased odds of leak with higher Modified Heckmatt Scale score. No statistically significant increase in leak was noted with higher volume of injectate or smaller muscle diameter. Extramuscular leak of botulinum toxin injection may be associated with fibroadipose muscle change.

Exploring the perceptions and experiences of diabetes management and self-regulation in young adults using a continuous glucose monitoring device

Young adults face many pressures as they start being independent and responsible for their own actions and decisions. The use of continuous glucose monitoring has been shown to improve medical outcomes in diabetes management, but the mechanism of these improvements needs further investigation. This study aimed to examine the self-regulatory experiences and behaviours of a group of young adults using continuous glucose monitoring to manage type 1 diabetes. An exploratory qualitative approach was taken, using six virtual semi-structured interviews with young adults living with type 1 diabetes and using continuous glucose monitoring. A thematic analysis was used to identify themes from the gathered data. In this study, three themes demonstrated reciprocal determinism in that the observation of the continuous glucose monitoring results led to changes in the behaviours of the participants. The concepts of feedback and feedforward were also evident in the information provided by continuous glucose monitoring and the adjustment of the participants to achieve their personal blood glucose goals. The results of this study thus support the fact that self-regulation of those living with type 1 diabetes can be improved using continuous glucose monitoring as a tool for observation of blood glucose fluctuations and can, as a result, lead to changes in diabetes management behaviours and health outcomes. Continuous glucose monitoring provides the opportunity to observe the consequences of diabetes management behaviours, which activates the self-regulation processes of feedback and feedforward. This process has the potential to improve diabetes management behaviours in this vulnerable group.

Comparative evaluation of hyaluronic acid-based dressing versus hydrocolloid dressing in rat dermal wound healing.

Wound healing is a complex process influenced by a variety of environmental factors. Dressing materials play a critical role in creating barriers against contaminants, maintaining optimal moisture levels, and absorbing wound exudate. Therefore, selecting materials tailored to wound characteristics is crucial for enhancing outcomes. Hyaluronic acid (HA) is a natural biocompatible polymer that supports healing by regulating inflammation and promoting tissue repair. This study compared HA- and hydrocolloid-based hydrogels in a rat model to optimize wound care strategies. Full-thickness dermal wounds (diameter, 8 mm) were created on the dorsal skin of 12 Sprague-Dawley rats under sevoflurane anesthesia. The wounds were treated with HA/silver sulfadiazine gel (group A), hydrocolloid gel (group B), or left untreated (control), all covered with a transparent dressing. Biopsy specimens on days 3, 7, and 21 were used to assess histological parameters: inflammatory cell infiltration, fibroblast infiltration, collagen deposition, neovascularization, and epithelial thickness, using a semi-quantitative scoring system. Histological analyses were conducted blindly, and statistical analyses were performed using the Kruskal-Wallis test (p< 0.05). On day 3, group A showed significantly higher inflammatory cell infiltration and collagen deposition than other groups, indicating extracellular matrix formation. By day 7, angiogenesis was highest in group A, followed by group B and controls. By day 21, all wounds had completely healed. Epithelial layer thickness, reflecting inflammation and fibroblast maturity, was significantly higher in group A. This study compared HA-based hydrogel and hydrocolloid-based dressings through histological analyses to elucidate wound healing mechanics. HA-based hydrogel dressings significantly enhanced wound recovery. However, generalizing these outcomes requires future studies to expand the range of effective wound treatment materials. These findings underscore the potential of HA-based dressings to enhance clinical outcomes in wound management, suggesting avenues for improving therapeutic strategies.

Outcome of End to Side Nerve Modified Double Oberlin Procedure and End to End Dorsal Approach Spinal Accessory to Suprascapular Nerve in Partial Postganglionic BPI: A Case Report

Introduction: Brachial plexus injury (BPI) is a devastating peripheral nerve injury that mostly affecting young men, often due to motor vehicle accidents. BPIs can be classified into preganglionic and postganglionic lesions, with postganglionic injuries allowing potential nerve regeneration. The Oberlin method, aimed at reinnervating the biceps, and the Mackinnon technique, targeting both biceps and brachialis muscles, have shown promising outcomes in BPI management. Case report: A 45-year-old man presented with right hand weakness and occasional tingling in the upper arm and fingers two months after a motorcycle accident. Motor examination revealed muscle strength of 0/5 in the right trapezius, rhomboids, serratus anterior (positive winging scapula), pectoralis minor and major, latissimus dorsi, deltoid, biceps, and elbow flexion. Wrist and finger functions remained intact. Diagnosed with post-ganglionic BPI, the patient underwent two nerve transfer surgeries: the Mackinnon technique, transferring the spinal accessory nerve to the suprascapular nerve to reinnervate shoulder muscles, and the Double Oberlin procedure, transferring fascicles from the median and ulnar nerves to the musculocutaneous nerve for reinnervation of the biceps and brachialis muscles. Post-surgery, the patient engaged in an aggressive rehabilitation program focusing on strength, range of motion, and sensory re-education. Over nine months, the patient showed significant improvement in elbow flexion (MRC grade 3), wrist extension (MRC grade 5), hand grip strength (MRC grade 3) with improved sensation across the affected limb. He returned to work and daily activities with mild residual weakness and sensory deficits. Discussion: This case illustrates the effectiveness of the Mackinnon and Double Oberlin nerve transfer techniques in restoring function in a patient with total post-ganglionic BPI. The Mackinnon technique enabled shoulder muscle reinnervation, essential for abduction and stabilization, while the Double Oberlin procedure enhanced elbow flexion by reinnervating both the biceps and brachialis muscles. The combined surgical and intensive rehabilitation approach facilitated significant functional recovery. Conclusion: The successful application of the Double Oberlin and Mackinnon techniques in this case demonstrates their potential in managing total post-ganglionic BPI. Early surgical intervention and consistent rehabilitation are crucial for optimizing recovery outcomes. This case highlights the importance of a multidisciplinary approach in treating complex peripheral nerve injuries. Keywords: Double Oberlin, Mackinnon, Brachial Plexus Injury

Relationship between human capital and entrepreneurship orientation from the intellectual capital perspective of innovative literacy

PurposeThis study measures the relationship between human capital and innovative literacy from the perspective of intellectual capital. For this purpose, the relationship between human capital and innovative literacy was first investigated to measure intellectual capital. Subsequently, the moderating effect of entrepreneurial orientation on the influence of innovative literacy on human capital was also analysed.Design/methodology/approachThis study analyses the relationship between innovative literacy, human capital and entrepreneurial orientation through structural equation modelling – the study sample comprised 457 participants in Türkiye.FindingsThe results suggest a positive relationship between human capital, a sub-component of intellectual capital and innovative literacy. Innovative literacy can influence intellectual capital and increase value. Our finding further confirms that entrepreneurial orientation has no moderating effect on the same relationship.Research limitations/implicationsDespite the observed correlation between IL and HC growth, this study had some limitations. First, the generalisability of the findings is limited because the sample was selected from individuals with a high level of education in Türkiye. Despite these limitations, this study has important theoretical and practical implications for developing countries. Türkiye is a developing country, and the selected sample is the most critical database in the country for an Innovative Literacy Scale. However, future research could focus on whether there is a potential source of bias and collect and compare data from heterogeneous workers. In addition, research on existing research frameworks in other countries may consider varying levels of education and business sectors. This research aims to be a pioneering initiative towards the advancement of IL. The question of whether IL should be considered equivalent to or a subset of HC, which has been previously proposed as a dimension of IC, can be clarified through a thorough examination of what IL means.Practical implicationsIn a theoretical framework, transforming human capital into value through innovations derived from innovative literacy activities will significantly increase the company's intellectual capital. Organizations in which innovative literacy play an important role achieve organizational goals, strengthen commitment and contribute to sustainability through the emergence of new potential innovative individuals. This research also contributes significantly to the existing literature. Initially regarding theoretical implications, this study examines the concept of innovative literacy in the existing literature on intellectual capital, human capital and entrepreneurial orientation. Additionally, this study offers a new perspective on intellectual capital.Social implicationsThe findings of this research also provide managerial outcomes. Initially, the assessment of concepts, research and development capabilities and efficient knowledge management are indicators of innovative literacy proficiency at the individual level. Human capital is a subcomponent of intellectual capital and refers to knowledge, skills and experience. Innovative and literate team members should be developed in order to strengthen the intellectual capital structure of an organization.Originality/valueThis study contributes to understanding innovative literacy from an intellectual capital perspective using the Innovative Literacy Scale to reveal important dimensions that influence innovative literacy. Using a measurement tool with new sub-dimensions not included in the extant literature on intellectual capital is unique. This study suggests that scholars should include innovative literacy – a distinct subset of intellectual capital – in their body of knowledge on human capital. Our findings have the potential to help meet the needs of human resource departments, researchers, educational institutions, public institutions and enterprises.

Mechanisms of HIF1A-mediated immune evasion in gastric cancer and the impact on therapy resistance

BackgroundThe high prevalence and detrimental effects on patient outcomes make gastric cancer (GC) a significant health issue that persists internationally. Existing treatment modalities exhibit limited efficacy, prompting the exploration of immune checkpoint inhibitors as a novel therapeutic approach. However, resistance to immunotherapy poses a significant challenge in GC management, necessitating a profound grasp of the intrinsic molecular pathways.MethodsThis study focuses on investigating the immunosuppressive mechanisms of quiescent cancer cells (QCCs) in GC, particularly their resistance to T-cell-mediated immune responses. Utilizing mouse models, gene editing techniques, and transcriptome sequencing, we aim to elucidate the interactions between QCCs, immune cells, and key regulatory factors like HIF1A. Functional enrichment analysis will further underscore the role of glycolysis-related genes in mediating immunosuppression by QCCs.ResultsThe cancer cells that survived GC treated with T-cell therapy lost their proliferative ability. QCCs, as the main resistance force to immunotherapy, exhibit stronger resistance to CD8+ T-cell attack and possess higher cancer-initiating potential. Single-cell sequencing analysis revealed that the microenvironment in the QCCs region harbors more M2-type tumor-associated macrophages and fewer T cells. This microenvironment in the QCCs region leads to the downregulation of T-cell immune activation and alters macrophage metabolic function. Transcriptome sequencing of QCCs identified upregulated genes related to chemo-resistance, hypoxia, and glycolysis. In vitro cell experiments illustrated that HIF1A promotes the transcription of glycolysis-related genes, and silencing HIF1A in QCCs enhances T-cell proliferation and activation in co-culture systems, induces apoptosis in QCCs, and increases QCCs' sensitivity to immune checkpoint inhibitors. In vivo, animal experiments showed that silencing HIF1A in QCCs can inhibit GC growth and metastasis.ConclusionUnraveling the molecular mechanisms by which QCCs resist T-cell-mediated immune responses through immunosuppression holds promising implications for refining treatment strategies and enhancing patient outcomes in GC. By delineating these intricate interactions, this study contributes crucial insights into precision medicine and improved therapeutic outcomes in GC management.

Enhanced patient journey associated with improved overall survival in colon cancer patients: A study by the Ligurian Oncology Network.

Colon cancer imposes a significant burden on global healthcare systems, necessitating efforts to improve oncology care quality and patient outcomes. We studied the correlation between care quality and survival outcomes among colon cancer patients within the Ligurian Oncology Network (Italy). We developed an Overall Quality Score (OQS) to evaluate the impact of oncology care quality on survival outcomes within the Ligurian Oncology Network. OQS indicators were selected through expert consensus, covering screening, diagnosis, treatment, and follow-up. A sample of colon cancer patients diagnosed in 2012 was randomly selected from administrative healthcare data. Analyses were performed using two models: a binary model (High and Low OQS) and a stratified model (Low, Medium, and High OQS). Statistical analysis involved survival curves, log-rank tests, and Cox proportional hazards models using SAS 9.4. Of 175 eligible colon cancer patients, 150 were included. Following a median follow-up of 7.6 years, a correlation between High-OQS (⩾ 65%) and prolonged disease-free survival was observed (unadjusted HR 0.57, 95%CI 0.33-0.99, log-rank p=0.041). The five-year disease-free survival rate for High-OQS patients was 70% (95%CI 57-80%), compared to 53% (95%CI 41-64%) for Low-OQS patients. Similarly, the five-year overall survival rate was 78% (95%CI 65-86%) for High-OQS patients, compared to 58% (95%CI 45-68%) for Low-OQS patients (unadjusted HR 0.56, 95%CI 0.31-1.00, log-rank p=0.048). Our findings highlight the potential impact of the patient journey on colon cancer survival outcomes. Optimising care pathways might improve patient outcomes in colon cancer management.

Validation and user experience of a dry electrode based Health Patch for heart rate and respiration rate monitoring

Successful implementation of remote monitoring of vital signs outside of the hospital setting hinges on addressing three crucial unmet needs: longer-term wear, skin comfort and signal quality. Earlier, we developed a Health Patch research platform that uses self-adhesive dry electrodes to measure vital digital biomarkers. Here, we report on the analytical validation for heart rate, heart rate variability and respiration rate. Study design included n = 25 adult participants with data acquisition during a 30-minute exercise protocol involving rest, squats, slow, and fast cycling. The Shimmer3 ECG Unit and Cosmed K5, were reference devices. Data analysis showed good agreement in heart rate and marginal agreement in respiratory rate, with lower agreement towards higher respiratory rates. The Lin’s concordance coefficient was 0.98 for heart rate and 0.56 for respiratory rate. Heart rate variability (RMSSD) had a coefficient of 0.85. Participants generally expressed a positive experience with the technology, with some minor irritation from the medical adhesive. The results highlighted potential of this technology for short-to-medium term clinical use for cardiorespiratory health, due to its reliability, accuracy, and compact design. Such technology could become instrumental for remote monitoring providing healthcare professionals with continuous data, remote assessment and enhancing patient outcomes in cardiorespiratory health management.

Outcome of donor lymphocyte infusion after allogeneic hematopoietic stem cell transplantation in relapsed myelodysplastic syndrome

Allogeneic hematopoietic stem cell transplantation (HSCT) improves outcomes for myelodysplastic syndrome (MDS) patients, but relapse rates remain high, and post-relapse treatment options are limited. Therefore, this study aimed to identify the factors contributing to the response to donor lymphocyte infusion (DLI) in relapsed MDS patients post-HSCT. This study included 107 patients with relapsed and DLI-treated MDS who underwent their first HSCT between 2002 and 2022 and were registered in the Transplant Registry Unified Program. Univariate and multivariate survival analyses were conducted using log-rank tests and Cox proportional hazards models. Overall survival (OS) and response rates to DLI were also analyzed. The 1-year OS was 30.0% and univariate analysis identified poor prognostic factors: age ≥58 years (P = 0.003), complex karyotype (P = 0.026), hematologic relapse (P = 0.026), and early relapse (P = 0.004). Azacitidine plus DLI also improved prognosis (P < 0.001). Multivariate analysis confirmed age ≥58 years, hematologic relapse, and early relapse as poor prognostic factors. The adjusted OS for patients aged ≥ 58 years who relapsed <110 days post-transplant showed that the 1-year OS in patients with cytogenetic/molecular relapse was 43.6%, compared to 9.4% for those with hematologic relapse. Acute GVHD occurred in 62.3% of patients, and chronic GVHD in 30.8%, with manageable outcomes. DLI may improve OS in younger patients, those with cytogenetic/molecular relapse, and those with late relapse. Despite the risk of GVHD, its impact on prognosis is minimal. Given the limited treatment options, DLI should be considered for relapsed MDS patients post-HSCT.

330 One-Year Outcomes in Operative Versus Non-Operative Management of Acute Appendicitis: Results of a Single State Multi-Year Study of Linked Statewide Databases

National Trends and Outcomes in the Operative Management of Thyroid Storm.

Thyroid storm is a rare but potentially lethal manifestation of thyrotoxicosis. Guidelines recommend nonoperative management of thyroid storm, but thyroidectomy can be performed if patients fail medical therapy or need immediate resolution of the storm. Outcomes of thyroidectomy for management of thyroid storm remain ill-defined. Using the National Inpatient Sample from 2016 to 2020, a retrospective analysis was conducted of patients admitted with thyroid storm. Outcomes of interest included operative complications and mortality. Multivariable logistic regression was performed to assess factors associated with receiving thyroidectomy and mortality. An estimated 16,175 admissions had a diagnosis of thyroid storm. The incidence of thyroid storm increased from .91 per 100,000 people in 2016 to 1.03 per 100,000 people in 2020, with a concomitant increase in mortality from 2.9% to 5.3% (P < .001). Operative intervention was pursued in 635 (3.9%) cases with a perioperative complication rate of 30%. On multivariable regression, development of acute decompensated heart failure (adjusted odds ratio [AOR] 1.66, 95% Confidence Interval [CI] 1.03-2.68, P = .037) and acute renal failure (AOR 2.10, 95% CI 1.17-3.75, P = .013) increased odds of receiving surgery. The same multivariable model did not show a significant association between thyroidectomy and mortality. The incidence of thyroid storm and associated mortality increased during the study period. Thyroidectomy is rarely performed during the same admission, with an overall perioperative complication rate of 30% and no effect on mortality. Patients with acute decompensated heart failure and renal failure were more likely to receive an operative intervention.
