The role of the ward nurse in recognition and response to clinical deterioration: a scoping review.

BACKGROUND: Nurses play a key role in the recognition and response to clinical deterioration. AIM: The aim of this scoping review was to explore, map and synthesise existing research related to the ward nurses' role in recognising and responding to clinical deterioration. METHODS: A scoping review was undertaken to identify English only studies focused on the ward nurse's role in recognition and response to clinical deterioration of the hospitalised adult. Search terms included 'clinical deterioration', 'nurses', 'wards', 'general', 'hospital, units' and 'hospitals'. The Cumulative Index to Nursing and Allied Health Literature, EMBASE, Ovid MEDLINE, PubMed, ProQuest and Science Direct databases were searched for eligible studies. RESULTS: Forty-six studies met the inclusion criteria and three major themes were synthesised: (i) recognition of deterioration; (ii) nursing assessment; and, (iii) challenges responding to patient deterioration. CONCLUSION: The review highlighted significant variability in the ward nurses' role, activities, and skills in assessing, monitoring, managing and escalating care for clinical deterioration.

A retrospective evaluation of SwePEWS use in paediatric patients with COVID-19 and RSV infection.

AIM: As early detection of deterioration is a challenge in children, the Swedish Paediatric Early Warning Score (SwePEWS) is used to systematically assess paediatric patients' clinical state. Here, we aimed to evaluate the use and predictive ability of SwePEWS. METHODS: Electronic health records of paediatric patients admitted due to respiratory syncytial virus infection or COVID-19 were reviewed retrospectively. Registered vital signs were compared to the assigned SwePEWS score and monitored vital sign values to identify discrepancies. Additionally, SwePEWS's ability to predict transfer to the paediatric intensive care unit (PICU) was assessed. RESULTS: Among 1374 SwePEWS assessments, one-third were either incomplete or contained errors. Incomplete SwePEWS assessments were more frequent during night-time. Single measurements of oxygen saturation presented lower values compared to average saturation from continuous monitoring. SwePEWS's ability to predict PICU transfer was low. CONCLUSION: There was a surprisingly high occurrence of underestimated SwePEWS scores. This study provides new insights into pitfalls when developing and implementing paediatric early warning scores for systematic re-evaluations in paediatric patients.

Consensus for the Development of a New Early Warning Score for Predicting Patients' Clinical Deterioration in Angola: A Delphi Study.

Background: Nearly 30 years since its inception, the early warning scores (EWSs) remain pivotal, yet variations have emerged for hospital and prehospital use. Aggregated scores, reflecting multiple physiological parameters, outperform single-parameter systems in assessing acute illness severity, though consensus on optimal approaches is lacking. Resource-limited countries, including Angola, lack adapted EWSs, emphasizing the need for cost-effective and adaptable solutions to enhance patient care. Objective: To explore the perspectives of Angolan experts to identify physiological parameters suitable for incorporation into existing EWSs, allowing the development of a new tool adjusted to the healthcare context in Angola. Methods: We conducted a three-round Delphi survey, engaging a national expert panel comprising twenty-five physicians and nurses with expertise in internal medicine, surgery, emergency rooms, intensive care units, and/or teachers at universities or at teaching courses in these fields. Participants were asked to rate items using a five-point Likert scale. Consensus was achieved if the items received a rating ≥ 80% from the panel. Results: Consensus was evident for the inclusion of standard physiological parameters, such as systolic blood pressure, heart rate, respiratory rate, temperature, oxygen saturation, neurological status, and the presence or absence of supplemental oxygen. Furthermore, there was consensus for the consideration of specific items, namely, seizures, jaundice, cyanosis, capillary refill time, and pain-typically not included in the current EWSs. Consensus was reached regarding the exclusion of both oxygen saturation and temperature measurements in healthcare settings where oximeters and thermometers might not be readily available. Conclusion: Angolan experts were able to identify the physiological parameters suitable for incorporation into the basic EWSs. Further study must be conducted to test and validate the impact of the newly suggested vital parameters on the discriminant and predictive capability of a new aggregated model specifically adjusted to the Angolan healthcare setting.

Events preceding death after high-risk surgery analyzed by Global Trigger Tool and reflective-thematic approach.

BACKGROUND: Postoperative mortality might be influenced by postoperative care, vigilance, and competence to rescue. This study aims to describe the course of events preceding death in a high-risk surgical cohort. METHODS: We analyzed hospital records of patients who died within 30 days after surgery in 4 high volume hospitals using (1) reflective narrative thematic approach to identify recurring themes reflecting issues with conduct of care and (2) Global Trigger Tool to describe incidence, timing, and types of adverse events (AEs) leading to harm. RESULTS: Preoperative predicted median risk of death in the studied group was 9%/13% according to SORT/P-POSSUM, respectively. Nine recurring themes were identified. Prominent themes were "consensus concerning aim and/or risk with planned surgery," "level of (intraoperative) competence and monitoring," and in the postoperative period "level of care and vigilance" on signs of deterioration. We found a total of 303 AEs, with only three patients (5%) having no adverse events. Most common severity category was "I," that is "contributed to patient's death" (n = 110, 36% of all AEs). Of these, 60% were classified as preventable or probably preventable. The peak incidence of AEs was seen on the day of index surgery. Most common types of AEs were "failure of vital functions" (n = 79, 26%), followed by infections (n = 45, 15%). CONCLUSIONS: A high predicted risk of death and a peak of adverse events on the day of index surgery were detected. Identified themes reflect lack of documented multi-professional consensus on how to handle prevalent perioperative risk, vigilance, and postoperative level of care.

Peripheral Lymphocyte-to-Monocyte Ratio as a Predictive Factor for Early Neurological Deterioration in Patients with Acute Ischemic Stroke.

Purpose: Previous studies have reported that lymphocyte-to-monocyte ratio (LMR) is associated with the prognosis of patients with acute ischemic stroke (AIS); however, the relationship between LMR and early neurological deterioration (END) in AIS patients has not been elucidated. Patients and Methods: Patients were divided into two groups according to LMR by using receiver operating characteristic (ROC) curve analysis. Patients with END were confirmed as the National Institutes of Health Stroke Scale (NIHSS) increased ≥ 4 points between hospital days 0 and 5. Multivariate logistic regression analysis was used to analyze the factors independently related to END in patients with AIS. Results: In total, 202 patients diagnosed with AIS were enrolled in this retrospective study. Using ROC curve analysis, patients were divided into two groups according to LMR: low LMR group (LMR < 3.24, n = 95) and high LMR group (LMR ≥ 3.24, n = 107). The frequencies of END were significantly higher in the low LMR group compared to the high LMR group (41.05 vs.15.89%, p < 0.001). Multivariate logistic regression showed that age (OR = 1.03, 95% CI 1.01-1.06, p = 0.04), infarct volume (OR = 1.01, 95% CI 1.00-1.02, p = 0.001), neutrophil count (OR = 1.17, 95% CI 1.03-1.33, p = 0.018), and LMR (OR = 2.49, 95% CI 1.01-9.11, p = 0.018) were independently associated with END in AIS patients. Conclusion: A peripheral LMR levels at admission were significantly associated with END and LMR < 3.24 is an independent predictive factor of END in patients with AIS.

Signs and symptoms in hospitalized children and adolescents' triggering nurses' awareness - A qualitative study across Denmark and Norway.

BACKGROUND: Assessment of signs and symptoms in hospitalized children presents unique challenges due to the children's age-related differences, such as vital signs and the broad range of medical conditions that affects children. Early detection of clinical changes in children is crucial to prevent deterioration, and while standardized tools exist, there is a growing recognition of the need to consider subjective factors based on experienced nurses' knowledge and intuition. OBJECTIVE: To explore which signs and symptoms, apart from vital signs, that trigger nurses' concern regarding deterioration of hospitalized children and adolescents. DESIGN: This study used a descriptive qualitative design. SETTINGS: The study was conducted at three pediatric departments in Denmark and a nursing department of a university in Norway, offering post graduate education programs for health care professions working with children and adolescents throughout Norway. PARTICIPANTS: A total sample of 29 registered nurses with varying levels of experience participated. METHOD: Four focus group interviews were used to collect data and analyzed with inductive content analysis approach. RESULTS: Nurses' knowledge about children's clinical conditions is influenced by the nurses experience, their use of senses like touching the child with their hands, and the use of various approaches. Information from parents about the child's normal behavior are considered valuable. These sources of information, often difficult to verbalize, might be referred to as intuition or "gut feeling" and often guides the nurses' actions when vital signs appear normal, and nurses rely on their senses to assess the child's condition. Specific indicators triggering concern include changes in respiration, circulation, level of consciousness, and facial expressions. Challenges arise from nighttime assessments, interactions with parents, the presence of electronic devices, and children's ability to compensate. Clinical experience is a significant factor in nurses' ability to recognize changes in in the child's condition. CONCLUSION: This study highlights the multifaceted nature of nurses' assessments of clinical conditions in hospitalized children. Nurses draw on their experiences, intuition, and interactions with parents to complement vital signs-based assessments. Their intuition, or "gut feeling" serves as a valuable tool when vital signs do not fully capture the child's clinical status. Specific signs and symptoms that trigger nurses' concern, along with the challenges they face, contribute to a comprehensive understanding of the complexity of assessing children's clinical conditions. These findings, emphasize the role of nurses in early recognition of clinical deterioration in hospitalized children and the need for assessments that go beyond vital signs. TWEETABLE ABSTRACT: Both objective assessments and intuitive clinical judgment play an important role in identifying potential deterioration in pediatric patients.

Durability Performance of CGF Stone Waste Road Base Materials under Dry-Wet and Freeze-Thaw Cycles.

The disposal of stone waste derived from the stone industry is a worldwide problem. The shortage of landfills, as well as transport costs and environmental pollution, pose a crucial problem. Additionally, as a substitute for cement that has high carbon emissions, energy consumption, and pollution, the disposal of stone wastes by utilizing solid waste-based binders as road base materials can achieve the goal of "waste for waste". However, the mechanical properties and deterioration mechanism of solid waste-based binder solidified stone waste as a road base material under complex environments remains incompletely understood. This paper reveals the durability performance of CGF all-solid waste binder (consisting of calcium carbide residue, ground granulated blast furnace slag, and fly ash) solidified stone waste through the macro and micro properties under dry-wet and freeze-thaw cycling conditions. The results showed that the dry-wet and freeze-thaw cycles have similar patterns of impacts on the CGF and cement stone waste road base materials, i.e., the stress-strain curves and damage forms were similar in exhibiting the strain-softening type, and the unconfined compressive strengths all decreased with the number of cycles and then tended to stabilize. However, the influence of dry-wet and freeze-thaw cycles on the deterioration degree was significantly different; CGF showed excellent resistance to dry-wet cycles, whereas cement was superior in freeze-thaw resistance. The deterioration grade of CGF and cement ranged from 36.15 to 47.72% and 39.38 to 47.64%, respectively, after 12 dry-wet cycles, whereas it ranged from 57.91 to 64.48% and 36.61 to 40.00% after 12 freeze-thaw cycles, respectively. The combined use of MIP and SEM confirmed that the deterioration was due to the increase in the porosity and cracks induced by dry-wet and freeze-thaw cycles, which in turn enhanced the deterioration phenomenon. This can be ascribed to the fact that small pores occupy the largest proportion and contribute to the deterioration process, and the deterioration caused by dry-wet cycles is associated with the formation of large pores through the connection of small pores, while the freeze-thaw damage is due to the increase in medium pores that are more susceptible to water intrusion. The findings provide theoretical instruction and technical support for utilizing solid waste-based binders for solidified stone waste in road base engineering.

Clinician perspectives and recommendations regarding design of clinical prediction models for deteriorating patients in acute care.

BACKGROUND: Successful deployment of clinical prediction models for clinical deterioration relates not only to predictive performance but to integration into the decision making process. Models may demonstrate good discrimination and calibration, but fail to match the needs of practising acute care clinicians who receive, interpret, and act upon model outputs or alerts. We sought to understand how prediction models for clinical deterioration, also known as early warning scores (EWS), influence the decision-making of clinicians who regularly use them and elicit their perspectives on model design to guide future deterioration model development and implementation. METHODS: Nurses and doctors who regularly receive or respond to EWS alerts in two digital metropolitan hospitals were interviewed for up to one hour between February 2022 and March 2023 using semi-structured formats. We grouped interview data into sub-themes and then into general themes using reflexive thematic analysis. Themes were then mapped to a model of clinical decision making using deductive framework mapping to develop a set of practical recommendations for future deterioration model development and deployment. RESULTS: Fifteen nurses (n = 8) and doctors (n = 7) were interviewed for a mean duration of 42 min. Participants emphasised the importance of using predictive tools for supporting rather than supplanting critical thinking, avoiding over-protocolising care, incorporating important contextual information and focusing on how clinicians generate, test, and select diagnostic hypotheses when managing deteriorating patients. These themes were incorporated into a conceptual model which informed recommendations that clinical deterioration prediction models demonstrate transparency and interactivity, generate outputs tailored to the tasks and responsibilities of end-users, avoid priming clinicians with potential diagnoses before patients were physically assessed, and support the process of deciding upon subsequent management. CONCLUSIONS: Prediction models for deteriorating inpatients may be more impactful if they are designed in accordance with the decision-making processes of acute care clinicians. Models should produce actionable outputs that assist with, rather than supplant, critical thinking.

Development of a scale to assess nurses' difficulties in collaborating with physicians in responding to clinical deterioration during night shifts.

AIMS: To develop a scale to assess difficulties that nurses experience when collaborating with physicians in responding to clinical deterioration during night shifts and identify factors associated with scoring using the developed scale. METHODS: A web-based questionnaire with a draft scale, the Nighttime Collaboration Difficulties between Nurses and Physicians for Nurses (NCDNP-N), was distributed to nurses working night shifts in acute-care hospitals across Japan. Data were collected between July and October 2023. Of 435 responses, 405 were examined for the NCDNP-N's psychometric validation, including structural validity, criterion-related validity, and reliability assessments. Multiple linear regression analysis was performed for 385 responses excluded by listwise methods to identify factors associated with NCDNP-N scores. RESULTS: The NCDNP-N has 10 items and three domains: Domain 1, dissatisfaction with physicians' actions; Domain 2, burden of working with night-shift physicians; and Domain 3, barriers to reporting during night shifts. Estimated reliability coefficients exceeded the recommended values. Multiple regression analyses demonstrated that more years of experience in the current ward and frequency of calling the covering physician at night were markedly associated with higher scores, whereas more nursing experience was associated with lower scores. CONCLUSION: We developed the NCDNP-N and confirmed its validity and reliability. The study results suggest that the responsibilities and competence of nurses working night shifts and communication with the night-covering physician are associated with difficulties in nighttime collaboration. The NCDNP-N may help identify challenges in clinical settings as well as can be utilized in the evaluation study for improving nighttime collaboration.

Ayurvedic Management of Presbycusis (Project TOPMAC): Protocol for an Exploratory Randomized Controlled Trial.

BACKGROUND: Presbycusis is characterized by sensorineural hearing loss in both ears at high frequencies, which affects more than half of the older adults by the age of 75 years and is often accompanied by tinnitus and cognitive deterioration. Unfortunately, there are no treatments available to restore hearing loss. Treatment mainly focuses on improving the quality of life and communication with hearing aids. Traditional medicine like Ayurveda also explains ailments of a similar nature as Badhirya and advises using drugs with antiaging and neuroprotective activity for treatment. In Ayurveda, Badhirya and Karnanada (senile deafness with tinnitus) are due to vitiation of Vata Dosha. Treatments such as topical oil pooling (Karnapurana) are usually advised to counter Vata, improve hearing capacity, and reduce tinnitus. Kshirabala Taila, a medicated oil formulation prepared with Sida cordifolia Linnaeus, is one of the most preferred oils for topical oil pooling in such conditions, as it has a definitive indication for sensory dysfunctions. Drugs like Withania somnifera (L.) Dunal (Ashwagandha) are also used, as they ameliorate neurodegeneration and help to improve cognitive dysfunction. OBJECTIVE: We propose an exploratory randomized controlled trial study for evaluating the efficacy of TOPMAC (Topical Oil Pooling with Kshirabala Taila and Supplementation of Ashwagandha Churna) in tinnitus suppression and hearing and cognitive function protection in patients aged 60-75 years with mild to moderate presbycusis. METHODS: A parallel, 2-group, exploratory randomized controlled trial will be conducted in an Indian Ayurvedic research center at its outpatient service. Participants (N=60) with mild to moderate presbycusis will be recruited by screening. Participants will be randomized (computer-generated 1:1) to receive either basic treatment and health education (BTHE) or BTHE+TOPMAC for 24 weeks. The primary objective is to compare the efficacy of TOPMAC with that of BTHE in the protection of hearing function. The secondary objective is to compare the efficacy of TOPMAC with that of BTHE in tinnitus suppression and cognitive function protection. RESULTS: This project was funded in January 2023. The institutional ethics committees at National Ayurveda Research Institute for Panchakarma (3/1/2020/NARIP/Tech/2036) and Institute for Communicative and Cognitive Neuro Sciences (IEC006) approved this study. The first patient was enrolled in September 2023; 22 participants were enrolled as of August 2024. The data analysis is yet to start, and the results are expected to be published by January 2025. CONCLUSIONS: If this exploratory trial is proven effective, it will steer the setting of a definitive randomized controlled trial to test whether the TOPMAC intervention can be incorporated as a cost-effective integrative approach for managing presbycusis. The Indian government has already launched a National Program for Prevention and Control of Deafness to benefit the deaf population. TOPMAC may later be considered for integration with the national program. TRIAL REGISTRATION: Clinical Trials Registry India CTRI/2023/04/051485; https://tinyurl.com/2h2hry3n.

Development and Validation of a Pediatric Hospital-Acquired Malnutrition (PHaM) Risk Score to Predict Nutritional Deterioration in Hospitalized Pediatric Patients: A Secondary Analysis Based on a Multicenter Prospective Cohort Study.

(1) Background: Hospital-acquired malnutrition in pediatric patients leads to adverse outcomes. This study aimed to develop and validate a pediatric hospital-acquired malnutrition (PHaM) risk score to predict nutritional deterioration. (2) Methods: This was a derivative retrospective cohort study for developing a PHaM risk score. The study included data from children aged 1 month-18 years admitted to pediatric wards in four tertiary care hospitals for at least 72 h between December 2018 and May 2019. Data on pediatric patients' characteristics, medical history, nutritional status, gastrointestinal symptoms, and outcomes were used for tool development. Logistic regression identified risk factors for nutritional deterioration, defined as a decline in BMI z-score ≥ 0.25 SD and/or ≥2% weight loss. A PHaM risk score was developed based on these factors and validated with an independent prospective cohort from July 2020 to March 2021. (3) Results: The study used a derivative cohort of 444 patients and a validation cohort of 373 patients. Logistic regression identified gastrointestinal symptoms, disease severity, fever, lower respiratory tract infection, and reduced food intake as predictors. The PHaM risk score (maximum 9 points) showed good discrimination and calibration (AUC 0.852, 95% CI: 0.814-0.891). Using a cut-off at 2.5 points, the scale had 63.0% sensitivity, 88.6% specificity, 76.1% positive predictive value, and 80.6% negative predictive value (NPV) when applied to the derivative cohort. The accuracy improved on the validation cohort, with 91.9% sensitivity and 93.0% NPV. (4) Conclusions: This PHaM risk score is a novel and probably effective tool for predicting nutritional deterioration in hospitalized pediatric patients, and its implementation in clinical practice could enhance nutritional care and optimize outcomes.

Dual Antiplatelet Therapy and Outcomes in Acute Mild to Moderate Stroke With Versus Without Large-Artery Atherosclerosis Post Hoc Analysis of ATAMIS.

BACKGROUND: We conducted a post hoc analysis of the ATAMIS (Antiplatelet Therapy in Acute Mild to Moderate Ischemic Stroke) trial to investigate whether the priority of clopidogrel plus aspirin to aspirin alone was consistent between patients with and without stroke pathogenesis of large-artery atherosclerosis (LAA). METHODS AND RESULTS: Patients with stroke classification randomized to a clopidogrel-plus-aspirin group and aspirin-alone group in a modified intention-to-treat analysis set of ATAMIS were classified into LAA and non-LAA subtypes. The primary outcome was early neurologic deterioration at 7 days, defined as a >2-point increase in National Institutes of Health Stroke Scale score compared with baseline, and safety outcomes were bleeding events and intracranial hemorrhage. We compared treatment effects in each stroke subtype and investigated the interaction. Among 2910 patients, 225 were assigned into the LAA subtype (119 in the clopidogrel-plus-aspirin group and 106 in the aspirin-alone group) and 2685 into the non-LAA subtype (1380 in the clopidogrel-plus-aspirin group and 1305 in the aspirin-alone group). Median age was 66 years, and 35% were women. A lower proportion of early neurologic deterioration was found to be associated with dual antiplatelet therapy in the LAA subtype (adjusted risk difference, -10.4% [95% CI, -16.2% to -4.7%]; P=0.001) but not in the non-LAA subtype (adjusted risk difference, -1.4% [95% CI, -2.6% to 0.1%]; P=0.06). No significant interaction was found (P=0.11). CONCLUSIONS: Compared with the non-LAA subtype, patients with stroke of the LAA subtype may get more benefit from dual antiplatelet therapy with clopidogrel plus aspirin with respect to early neurologic deterioration at 7 days.

Association between the atherogenic index of plasma and early neurological deterioration in mechanical thrombectomy patients.

BACKGROUND AND PURPOSE: Atherogenic index of plasma (AIP) is a newly identified as marker of lipid metabolism and glucose metabolism, showing significant predictive value in individuals with cardiovascular disease. This study aimed to explore the correlation between AIP and early neurological deterioration (END) in ischemic stroke patients after mechanical thrombectomy (MT). METHODS: Patients with anterior circulation large artery occlusive stroke who underwent MT were retrospectively enrolled from 2 stroke center in China. The AIP is a logarithmically transformed ratio of triglycerides to high-density lipoprotein cholesterol. END was defined as an increase of ≥ 4 point in National Institutes of Health Stroke Scale within 24 hours after surgery. Multivariable regression analysis and restricted cubic spline was utilized to determine the association of AIP index with risk of END. RESULTS: Of 601 patients (mean age, 70.2 ± 12.1 years; 62.1 % of male) enrolled, 91 (15.1 %) experienced postoperative END. After adjustment for potential confounders, higher AIP levels were significantly associated with an increased risk of END after MT treatment (Per 1-standard deviation increase; odd ratio, 1.474; 95 % confidence interval, 1.162-1.869, P = 0.001). Similar results were confirmed when the AIP was analyzed as a categorical variable. Restricted cubic spline further demonstrated a linear relationship between AIP and risk of END (P = 0.001 for linearity). CONCLUSIONS: The present study found that a higher AIP index were associated with END in acute ischemic stroke patients following MT treatment for emergent large vessel occlusion.

Preliminary results on temporal evolution and clinical implications of atherosclerotic plaque in branch atheromatous disease after statin treatment.

Background: Branch atheromatous disease (BAD) is a primary cause of early neurological deterioration (END) in penetrating artery occlusion, leading to poor functional outcomes. While it has been proposed to classify BAD under large artery atherosclerosis, uncertainty exists regarding the optimal treatment strategy, including cholesterol-lowering targets. Objectives: We aimed to assess the clinical implications and temporal changes of atherosclerotic plaques before and after high-intensity statin treatment. Design: This is a high-resolution vessel-wall imaging sub-analysis of the trial of Statin and Dual Antiplatelet Therapy in Preventing Early Neurological Deterioration in Branch Atheromatous Disease (SATBRAD). Methods: In this prospective, single-group cohort study, participants in the treatment arm of the SATBRAD trial received early dual antiplatelet therapy and high-intensity statin treatment. The majority of these participants subsequently underwent high-resolution vessel-wall magnetic resonance imaging (MRI). Those with atheromatous plaques in the parent artery continued high-intensity statin treatment for 6 months, followed by a repeat MRI to monitor plaque changes. Results: There were 57 patients who underwent vessel-wall imaging and 24 exhibited contrast-enhanced plaques. Patients with contrast-enhanced plaques showed higher rates of END (29.2% vs 6.1%, p = 0.027), perfusion defects (62.5% vs 24.2%, p = 0.004), and lower rates of good outcomes at 3 months (50.0% vs 81.8%, p = 0.011). After adjusting for confounding factors, contrast-enhanced plaque had a negative impact on achieving a good outcome at 3 months (adjusted odds ratio = 0.04; 95% confidence interval = <0.01-0.60). Following high-intensity statin treatment in 36 patients, there was a notable reduction in stenosis (33.7% vs 29.3%, p = 0.005) and contrast-enhanced plaque volume (16.3 vs 11.6 mm3, p = 0.015). Conclusion: The study highlighted the association between contrast-enhanced atherosclerotic plaques, END, and poor functional outcomes, with high-intensity treatment leading to plaque volume reduction. These results underscore the shared pathology between BAD and intracranial atherosclerosis, emphasizing the necessity for further research and tailored treatment strategies for BAD. Trial registration: ClinicalTrials.gov; Identifier: NCT04824911 (https://clinicaltrials.gov/study/NCT04824911).

Changes in atherosclerosis and its impact on health after statin treatment: what we learned from detailed vessel imaging in the SATBRAD trial Branch atheromatous disease (BAD) is a major cause of early worsening of stroke symptoms, leading to poor recovery. While some experts believe BAD should be treated like large artery disease, the best treatment approach, including cholesterol-lowering targets, remains unclear. This study aimed to assess how high-intensity statin treatment affects atherosclerotic plaques over time and its impact on patient health. Analyzing detailed vessel images from the SATBRAD trial, where patients received high-intensity statins and magnetic resonance imaging, revealed that 24 out of 57 patients had plaques that showed up clearly with contrast enhancement. These patients were more likely to experience early worsening of stroke symptoms and perfusion compromise and had poorer outcomes. After six months of high-intensity statin treatment, there was a significant reduction in plaque size and vessel narrowing. The study concluded that contrast-enhanced plaques are linked to worse early stroke symptoms and poor recovery, but high-intensity statin treatment can reduce plaque size, suggesting that BAD may share similarities with larger artery disease and highlighting the need for further research and tailored treatments for BAD.

Machine learning-based prediction of early neurological deterioration after intravenous thrombolysis for stroke: insights from a large multicenter study.

Background: This investigation seeks to ascertain the efficacy of various machine learning models in forecasting early neurological deterioration (END) following thrombolysis in patients with acute ischemic stroke (AIS). Methods: Employing data from the Shenyang Stroke Emergency Map database, this multicenter study compiled information on 7,570 AIS patients from 29 comprehensive hospitals who received thrombolytic therapy between January 2019 and December 2021. An independent testing cohort was constituted from 2,046 patients at the First People's Hospital of Shenyang. The dataset incorporated 15 pertinent clinical and therapeutic variables. The principal outcome assessed was the occurrence of END post-thrombolysis. Model development was executed using an 80/20 split for training and internal validation, employing classifiers like logistic regression with lasso regularization (lasso regression), support vector machine (SVM), random forest (RF), gradient-boosted decision tree (GBDT), and multi-layer perceptron (MLP). The model with the highest area under the curve (AUC) was utilized to delineate feature significance. Results: Baseline characteristics showed variability in END incidence between the training (n = 7,570; END incidence 22%) and external validation cohorts (n = 2,046; END incidence 10%; p < 0.001). Notably, all machine learning models demonstrated superior AUC values compared to the reference model, indicating their enhanced predictive capacity. The lasso regression model achieved the highest AUC at 0.829 (95% CI: 0.799-0.86; p < 0.001), closely followed by the MLP model with an AUC of 0.828 (95% CI: 0.799-0.858; p < 0.001). The SVM, RF, and GBDT models also showed commendable AUCs of 0.753, 0.797, and 0.774, respectively. Decision curve analysis revealed that the SVM and MLP models demonstrated a high net benefit. Feature importance analysis emphasized "Onset To Needle Time" and "Admission NIHSS Score" as significant predictors. Conclusion: Our research establishes the MLP and lasso regression as robust tools for predicting early neurological deterioration in acute ischemic stroke patients following thrombolysis. Their superior predictive accuracy, compared to traditional models, highlights the significant potential of machine learning approaches in refining prognosis and enhancing clinical decisions in stroke care management. This advancement paves the way for more tailored therapeutic strategies, ultimately aiming to improve patient outcomes in clinical practice.

Mechanical impact of regional structural deterioration and tissue-level compensation on proximal femur trabecular bone.

Introduction: Osteoporosis-induced changes in bone structure and composition significantly reduce bone strength, particularly in the human proximal femur. This study examines how these changes affect the mechanical performance of trabecular bone to enhance diagnosis, prevention, and treatment strategies. Methods: A proximal femur sample was scanned using micro-CT at 40 µm resolution. Five regions of interest were selected within the femoral head, femoral neck, and greater trochanter. Structural models simulating various stages of osteoporosis were created using image processing software. Micro-finite element analysis evaluated the mechanical properties of trabecular bone under different conditions of structural deterioration and tissue-level elastic modulus variations. The combined effects of structural deterioration and tissue-level mechanical properties on trabecular bone mechanical performance were further analyzed. Results: The mechanical performance of trabecular bone generally follows a power-law relationship with its microstructural characteristics. However, in any specific region, the apparent mechanical properties linearly decrease with structural deterioration. The femoral neck and greater trochanter are more sensitive to structural deterioration than the femoral head. A 5% bone mass loss in the femoral head led to a 7% reduction in mechanical performance, while the femoral neck experienced a 12% loss. Increasing tissue-level elastic modulus improved mechanical performance, partially offsetting bone mass reduction effects. Conclusion: Trabecular bone in low bone mass regions is more affected by bone mass loss. Structural deterioration primarily reduces bone strength, but improvements in tissue-level properties can mitigate this effect, especially in early osteoporosis. Targeted assessments and interventions are crucial for effective management. Future research should explore heterogeneous deterioration models to better understand osteoporosis progression.

Quality control of cooked rice: Exploring physicochemical changes of the intrinsic component in production.

Sensory deterioration exists in marketed cooked rice. The migration and interaction of intrinsic components occur under multiple conditions in each industrial production process and cause relevant physicochemical changes in cooked rice. This review aims to establish a scientific knowledge system of intrinsic component transition and migration in cooked rice kernel during processing to solve qualitative deficiencies in cooked rice products. The main influencing factors of intrinsic component structural change in cooked rice and the quality control points that should be considered are summarized. Further studies are needed to establish proper evaluation standards for cooked rice products to meet the growing consumer demands.

Study of Biochemical Predictors of Early Neurological Deterioration in Ischemic Stroke in a Tertiary Care Hospital.

Background and objective Early neurological deterioration (END) following acute ischemic stroke (AIS) poses a significant clinical challenge, often leading to increased disability and mortality. This study aimed to investigate the association between specific biomarkers (lactate dehydrogenase (LDH), ferritin, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), homocysteine) and the occurrence of END in ischemic stroke patients in a tertiary care hospital. Materials and methods A cross-sectional hospital-based study was conducted at Dr. D. Y. Patil Medical College and Hospital, Pune, from July 2022 to April 2024. Patients aged 18 and above with confirmed ischemic stroke were included, while those with hemorrhagic stroke, intracranial tumors, mass effect with midline shift, or extensive cerebral edema were excluded. Upon admission, patients were assessed using the National Institutes of Health Stroke Scale (NIHSS) and monitored daily for seven days. Biomarkers, including LDH, ferritin, ESR, CRP, and homocysteine, were measured, and patients were categorized into those with END and without END. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 20 (Released 2011; IBM Corp., Armonk, New York). Results Out of 100 patients, 12% experienced END. The mean age of patients with END was 53.50 ± 11.20 years, compared to 53.62 ± 11.74 years in those without END (p = 0.790). Males constituted 91.7% of the END group and 73.9% of the non-END group (p = 0.284). A significant association was found between END and alcohol use (41.7% in END vs. 12.5% in non-END, p = 0.010) and tobacco use (41.7% in END vs. 11.4% in non-END, p = 0.010). The mean NIHSS scores were significantly higher in the END group on day 1 (11.58 ± 3.06 vs. 7.69 ± 3.98, p = 0.002) and on day 3 (13.92 ± 3.15 vs. 6.00 ± 3.65, p = 0.001). Biomarker analysis showed a significant difference in the mean vitamin B12 levels between END and non-END groups (93.17 ± 48.58 vs. 183.45 ± 349.33, p = 0.025). Conclusion Our study identified significant predictors of END in ischemic stroke patients, including alcohol and tobacco use, higher initial NIHSS scores, and elevated levels of LDH, ferritin, ESR, CRP, and homocysteine, along with low vitamin B12 levels. These findings highlight the importance of routine biochemical assessments and personalized treatment plans in managing AIS, emphasizing lifestyle changes and nutritional support to improve outcomes. Limitations include the single-center design, small sample size, and lack of long-term follow-up data. Future research should validate these findings in larger, multicenter studies and explore their long-term impact on stroke recovery.

Neutrophil-to-Lymphocyte Ratio, Lymphocyte-to-Monocyte Ratio and Platelet-to-Lymphocyte Ratio as Predictors of Short- and Long-Term Outcomes in Ischemic Stroke Patients with Atrial Fibrillation.

Purpose: Inflammatory response plays essential roles in the pathophysiology of both ischemic stroke and atrial fibrillation (AF). We aimed to investigate whether composite inflammatory markers, including neutrophil to lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR) and platelet-to-lymphocyte ratio (PLR), can serve as early predictors of short- and long-term outcomes in ischemic stroke patients with AF. Patients and Methods: Ischemic stroke patients with AF were enrolled in this cohort study. The primary outcome was 1-year functional dependence or death (modified Rankin scale (mRS) score 3-6). Secondary outcomes included hemorrhagic transformation (HT) and early neurological deterioration (END, increase in the National Institutes of Health Stroke Scale (NIHSS) ≥4 within 7 days). Partial correlations were performed to assess the correlation between systemic inflammation markers and admission NIHSS scores. Univariate and multivariate logistic analyses were performed to investigate whether systemic inflammatory markers were independent predictors of adverse outcomes. Results: A total of 408 patients were included. Partial correlation analysis revealed statistically significant but weak correlations between the NLR (r = 0.287; P < 0.001), PLR (r = 0.158; P = 0.001) and admission NIHSS score. Compared with patients without HT or END, patients who developed HT or END had higher NLR and PLR, and lower LMR. Patients in the functional dependence or death group had significantly higher NLR and PLR, and lower LMR than those in the functional independence group (all P < 0.001). Multivariate logistic analysis indicated that NLR, LMR and PLR were independent predictors of HT (OR = 1.069, 0.814 and 1.003, respectively), END (OR = 1.100, 0.768 and 1.006, respectively) and adverse 1-year functional outcome (OR = 1.139, 0.760 and 1.005, respectively). Conclusion: NLR, LMR and PLR were independent predictors for in-hospital HT, END and long-term functional outcome in ischemic stroke patients with AF. Close monitoring of these inflammatory markers may help guide risk stratification and clinical treatment strategies.
