Better Outcomes For Patients Research Articles

Revascularization of myocardial infarction without ST segment elevation in multivessel coronary artery disease

Many patients with non-ST elevation myocardial infarction have multivessel coronary artery disease, which complicates the course of the disease and is associated with fatal outcomes. Most patients with non-ST elevation myocardial infarction undergo coronary angiography and revascularization during initial hospitalization. However, the decision to perform total or incomplete revascularization and whether to perform total revascularization on admission or at the stage of its implementation is complex and must be adapted to the age, general condition of the patient and comorbidities. Sincethe majority of patients with non-STelevation myocardial infarction have multivessel disease, treatment and timing are critical components to ensure favorable outcomes. Early revascularization is associated with improved long-term patient outcomes, but the optimal approach to revascularization in patients with non-ST elevation myocardial infarction with multivessel disease remains poorly understood. However, in this patient population, a multidisciplinary cardiac approach is recommended to determine revascularization options. Published data suggest that evaluation of the risk-benefit associated with future invasive procedures should be based on an analysis of the patient's general condition and cardiovascular risk factors, the ability to identify the culprit artery, the technical feasibility of performing multivessel revascularization, and the location, degree of stenosis, and severity of lesions.Whether multivessel percutaneous coronary intervention or coronary artery bypass grafting provides better outcomes in patients with non-ST elevation myocardial infarction remains largely debatable. In this connection, it is relevant to conduct prospective studies to study the optimal revascularization strategies.

PDOC-10 LIMITATIONS IN POST OPERATIVE- ADJUVANT CARE OF PATIENTS WITH BRAIN TUMOURS-A CASE OF SUPRATENTORIAL MEDULLOBLASTOMA IN A PAEDIATRIC PATIENT

Abstract OBJECTIVE To highlight the challenges and limitations in accessing post-operative adjuvant care of patients with brain tumours in Zimbabwe and implications on patient outcomes and to discuss potential strategies to overcome these challenges. METHODS This is a case report on a 6 year old patient with a supratentorial medulloblastoma to demonstrate the challenges encountered on accessing post-operative adjuvant care at a Central hospital in Harare. RESULTS The patient had a near total resection of the tumour done and was managed in the Intensive care unit for 1 week. HE was discharged to the general ward for another week and eventually referred to the paediatric oncologists after a histological diagnosis of a supratentorial medulloblastoma was made. Patient received cycles of chemotherapy but failed to raise money for adjuvant radiotherapy. Patient returned 5 months later with the tumour having recurred. CONCLUSION Limitations in post-operative adjuvant care may have a negative impact on the overall patient outcomes, in this case lack of access to radiotherapy. Medulloblastomas are responsive to radiotherapy and their prognosis improves significantly with a combination of surgical resection and radiotherapy. Addressing these limitations at different levels involving government and non-governmental organizations helps in mitigating inaccessibility of radiotherapy to radio-sensitive brain tumours patients after surgical resection. This case report brings out the urgent need to implement cheaper and sustainable options to address challenges in post-operative adjuvant care in order to get good patient outcomes.

Total Marrow and Lymphoid Irradiation (TMLI) Is Associated with Good Early Outcomes in Patients Undergoing Matched Sibling Donor and Haplo-identical Transplants for Acute Lymphoblastic Leukemia

Total marrow and lymphoid irradiation [TMLI] can deliver higher doses of irradiation without increased toxicity. This study evaluated TMLI and Cyclophosphamide in patients undergoing stem cell transplantation for acute lymphoblastic leukemia [ALL] . Fifty-eight patients underwent matched related, unrelated or haplo-identical donor transplant using TMLI. The graft source was PBSC in all while GVHD prophylaxis consisted of cyclosporine with methotrexate or post-transplant cyclophosphamide. The median age was 20 years [range: 5 - 49] and included 20 children. Engraftment occurred in 56 [96.5%] at median of 15 days [range: 12 - 23] with 2 early deaths. Sinusoidal obstruction syndrome [SOS] was seen in 10 patients while hemorrhagic cystitis and cardiac dysfunction occurred in 2 patients each. Cumulative incidence of grade II - IV acute GVHD was 23.6% while grade III - IV was 10.9%. Chronic GVHD was seen in 46.9% while relapse was seen in 10 patients [17.2%]. The 2-year overall survival [OS] was 65.9 ± 6.8% and 2-year disease free survival [DFS] was 59 ± 6.7%. Outcomes were compared with 52 patients who received either Cy/TBI or Flu/Bu4 for conditioning during the same period. Engraftment rates and time to engraftment were similar. Acute GVHD [p = 0.002], regimen related toxicity [p = 0.043] and Day 100 non-relapse mortality [p = 0.020] were significantly lower with TMLI. TMLI was associated with better OS [p = 0.004] and DFS [p = 0.005] for haplo-identical transplants. Better DFS was seen with TMLI in patients with high-risk disease [p = 0.007] and disease status > CR1 [p = 0.041]. The use of TMLI and cyclophosphamide is associated with good outcomes in patients undergoing HSCT for ALL especially with haploidentical stem cell transplants.

Pedicled Anterolateral Thigh Flap (ALT) for Vulva Reconstruction: Journey to a New Horizon

AbstractSurgery for vulval malignancies necessitates extensive resection necessitating the use of musculocutaneous grafts. We present one such case where the patient needed both a V–Y plasty and an anterolateral thigh flap to ensure a tension-free repair. She underwent a partial deep vulvectomy followed by V–Y plasty and ALT flap. The procedure has been described in detail along with intraoperative photographs. She recovered uneventfully and is receiving post-operative adjuvant radiotherapy. We would like to highlight this “additional skill” of plastic surgery which will empower surgeons to undertake radical surgeries to ensure the best outcomes for patients.

Oscillatory and nonoscillatory sleep electroencephalographic biomarkers of the epileptic network.

In addition to the oscillatory brain activity, the nonoscillatory (scale-free) components of the background electroencephalogram (EEG) may provide further information about the complexity of the underlying neuronal network. As epilepsy is considered a network disease, such scale-free metrics might help to delineate the epileptic network. Here, we performed an analysis of the sleep oscillatory (spindle, slow wave, and rhythmic spectral power) and nonoscillatory (H exponent) intracranial EEG using multiple interictal features to estimate whether and how they deviate from normalcy in 38 adults with drug-resistant epilepsy. To quantify intracranial EEG abnormalities within and outside the seizure onset areas, patients' values were adjusted based on normative maps derived from the open-access Montreal Neurological Institute open iEEG Atlas. In a subset of 29 patients who underwent resective surgery, we estimated the predictive value of these features to identify the epileptogenic zone in those with a good postsurgical outcome. We found that distinct sleep oscillatory and nonoscillatory metrics behave differently across the epileptic network, with the strongest differences observed for (1) a reduction in spindle activity (spindle rates and rhythmic sigma power in the 10-16 Hz band), (2) a higher rhythmic gamma power (30-80 Hz), and (3) a higher H exponent (steeper 1/f slope). As expected, epileptic spikes were also highest in the seizure onset areas. Furthermore, in surgical patients, the H exponent achieved the highest performance (balanced accuracy of .76) for classifying resected versus nonresected channels in good outcome patients. This work suggests that nonoscillatory components of the intracranial EEG signal could serve as promising interictal sleep candidates of epileptogenicity in patients with drug-resistant epilepsy. Our findings further advance the understanding of epilepsy as a disease, whereby absence or loss of sleep physiology may provide information complementary to pathological epileptic processes.

Improving risk stratification for 2022 European LeukemiaNet favorable-risk patients with acute myeloid leukemia

Assignment of patients diagnosed with acute myeloid leukemia (AML) to the 2022 European LeukemiaNet (ELN) Favorable genetic-risk group has important clinical implications, as allogeneic stem-cell transplantation in first complete remission (CR) is not advised due to a relatively good outcome of patients receiving chemotherapy alone and transplant-associated mortality. However, not all Favorable genetic-risk patients experience long-term relapse-free survival (RFS), making recognition of patients who would most likely be cured of high importance. We analyzed 297 patients aged <60 years with de novo AML classified as 2022 ELN Favorable genetic-risk who achieved a CR and had RNA-seq and gene mutation data from diagnostic samples available (Alliance trial A152010). To identify prognostically relevant transcripts that can distinguish patients cured from patients susceptible to lower- or higher-risk of relapse or death, we fit a regularized mixture cure model (MCM), where RNA-seq expression values were our candidate covariates. To validate the identified transcripts, we analyzed 75 patients with de novo AML aged <60 years included in the 2022 ELN Favorable genetic-risk group who achieved a CR in an independent test set from Gene Expression Omnibus (GSE37642). Our MCM identified 145 transcripts associated with cure, or long-term RFS, and 149 transcripts associated with latency, or shorter-term time-to-relapse. The area under the curve and C-statistic were, respectively, 0.946 and 0.856 for our training and 0.877 and 0.857 for our test sets. Our results suggest that the Favorable-risk group includes distinct transcriptionally defined subgroups with different biological properties, which may be useful for refining this genetic-risk category.

An Evaluation of The Older Persons Presentation To The Emergency Department (ED) Following A Fall/Syncope/Presyncope

Abstract Background Falls events are a leading reason for presentations to the ED, particularly in older adults. Often these events are unwitnessed and unexplained. Therefore, there is strong consensus that the management of unexplained falls should be evaluated in a similar fashion to syncope as outlined by the World Falls and European Society of Cardiology guidelines. Methods The aim of this study was to evaluate adherence with current falls/syncope guidelines. Consecutive patients over the age of 75 who presented with a fall or syncope to a university teaching hospital in October 2023 were included. Data was collected on diagnostics completed (ECG, CT Brain, Carotid Doppler Ultrasound, EEG, pro BNP, Troponin, Echocardiogram, and External loop recorder), whether specialist falls review was performed, and readmission within 6 months. Completion of diagnostic tests were compared between those who were and were not reviewed by a specialist service using the Chi squared test. Results Falls/syncope/presyncope comprised 17.5% (160/913) of presentations of older people to the ED. Overall, 43% (n=68) had an ECG completed, 15% (n=23) had a pro BNP, and 24% (n=38) had a troponin level measured, 11% (n=17) had an Echo performed, and 10% (n=16) had prolonged cardiac monitoring (R test), 47% (n=74) had a CT Brain performed. Among those who were reviewed by a specialist falls service, (39% n= 62) completion of recommended investigations was significantly higher; ECG (69% v 26%, p&amp;lt;0.01), pro BNP (24% v 8.3%, p&amp;lt;0.01), echocardiogram (21% v 4.2%, p&amp;lt;0.01), cardiac monitoring (18% v 5.2%, p&amp;lt;0.01). Conclusion Falls and syncope are common presentations to the ED among older adults. Patients who were seen by a specialist falls team were more likely to have the appropriate diagnostics complete. Therefore, a specialist falls/syncope pathway led by a specialist falls service in the ED could result in better outcomes for patients.

Distant metastasis patterns among lung cancer subtypes and impact of primary tumor resection on survival in metastatic lung cancer using SEER database.

This research aimed to systematically uncover the metastatic characteristics and survival rates of lung cancer subtypes and to evaluate the impact of surgery at the primary tumor site on cancer-specific survival in DM lung cancer. We used the Surveillance, Epidemiology, and End Results (SEER) database (2010-2019) to identify primary lung cancers with DM at presentation (M1). Kaplan-Meier (KM) survival curves were generated and compared utilizing log-rank tests. Cox regression methods were employed to determine hazard ratios (HR) and 95% confidence intervals related to CSS factors. Inverse probability of treatment weighting (IPTW) was applied to reduce bias. We analyzed 77,827 M1 lung cancer cases, with 41.22% having DM at presentation. Bone metastasis was most common in ADC, ASC, SCC, LCC; brain in LCNEC; liver in SCLC. Lung was common in TC + AC and SCC. Long-term survival was best in TC + AC and worst in SCLC (p < 0.001). Male gender, age < 50, primary tumor site (main bronchus, lower lobe), large tumor diameter, ADC/SCLC/SCC pathology, and regional lymph node involvement were significant risk factors for multiorgan metastasis. Age ≥ 50, male, large tumor diameter, positive lymph nodes, and multiorgan metastases were associated with lower CSS. In contrast, radiotherapy, chemotherapy, systemic therapy, and surgery were associated with higher CSS rates. Primary tumor resection improved survival in lung cancer patients (excluding small cell lung cancer, SCLC) with single organ metastases (KM log rank p < 0.001, HR = 0.6165; 95% CI (0.5468-0.6951)), especially in brain (p < 0.001, HR = 0.6467; 95% CI (0.5505-0.7596)) and bone (p = 0.182, HR = 0.6289; p < 0.01), but not in liver or intrapulmonary metastases after IPTW. Significant differences in DM patterns and corresponding survival rates exist among lung cancer subtypes. Primary tumor resection improves survival in lung cancer patients (excluding small cell lung cancer, SCLC) with single organ metastases, with better outcomes in patients with brain and bone metastases, while no significant benefit was seen in patients with liver and intrapulmonary metastases.

A prospective study comparing intra-operative and postoperative complications in totally extra peritoneal repair vs extended totally extra peritoneal for inguinal hernia

Introduction: Inguinal hernia repair is one of the most common surgical procedures worldwide. Total extra peritoneal repair (TEP) and Extended-TEP (eTEP) are widely used minimally invasive methods. TEP involves creating a space in the preperitoneal plane without entering the abdominal cavity, whereas eTEP extends this approach, allowing for a broader operative field.This study compares the intra-operative and postoperative complications of TEP and eTEP, contributing to the optimisation of inguinal hernia management. Methods: It is a prospective study. A total of 60 patients who underwent TEP and e-TEP for inguinal hernia, who fulfilled the inclusion criteria. Patients were randomised by simple random sampling technique and were divided into two groups of 30 each (group A-TEP and group B-eTEP). Data of both groups were compared and analysed for statistical significance using Chi square test and Student ‘t’ test. Result: The comparative analysis between TEP and eTEP procedures shows no significant differences in demographic parameters. However, eTEP demonstrates significantly shorter operative time and hospital stay, quicker return to work. Both procedures have similar rates of low intra-operative and postoperative complications, indicating comparable safety profiles. Conclusion: Our study suggest that both techniques are associated with low complication rates and good patient outcomes, with eTEP showing potential advantages in terms of pain, recovery and wider access. These findings help to take better surgical decision, to make and helped optimize patient care in inguinal hernia management.

Some minutes matter more: Groin-to-recanalization is the main time-related predictor of outcome in acute ischemic stroke.

Endovascular thrombectomy (EVT) is the standard of care for selected patients with acute ischemic stroke (AIS) and large vessel occlusion (LVO), associated with intravenous thrombolysis, when indicated. While many studies focused on pre-hospital and in-hospital pathways, only few analyzed the relationship between groin-to-recanalization (GTR) time and functional outcome. To explore whether GTR time is an independent predictor of outcome in patients undergoing EVT. All patients with anterior circulation stroke treated with EVT at a high-volume center from January 2021 to December 2023 were included. The cohort was divided into two groups according to GTR time shorter or longer than 30 min. Regression analysis assessed the association between GTR time and 3-month good outcome, defined as modified Rankin Scale 0-2. The study included 419 patients. The groups had similar baseline characteristics and similar onset to recanalization (OTR) time. Regression analysis showed shorter GTR time is an independent predictor of favorable outcome (OR 2.49 [95% CI 1.26-4.94]). Age, baseline NIHSS, ASPECT score and bridging IVT were also found to be independently associated with outcome. Our study showed GTR time is an independent predictor of good outcome in patients undergoing EVT with similar OTR time, emphasizing procedural time as a key prognostic factor, even greater than other well-known pre-hospital and in-hospital time-dependent variables. These findings may raise the issue of developing alternative approaches or early "rescue" strategies for complicated procedures.

Real-world evidence of survival outcomes in breast cancer subtypes after neoadjuvant chemotherapy in a Brazilian reference center.

Neoadjuvant chemotherapy (NAC), traditionally used for locally advanced disease, is now applied for operable disease, particularly to treat aggressive breast cancer (BC). This study aimed to characterize the pathological complete response (pCR) and its relationship with overall survival (OS) and disease-free survival (DFS) among BC patients receiving NAC in a Brazilian public reference center, as well as the association between pCR and BC subtypes. A retrospective cohort study used a comprehensive BC database from a Brazilian women's health reference center, including patients diagnosed between 2011 and 2020 who underwent NAC. We collected demographic, cancer-specific, and treatment-related data, analyzing OS and DFS based on pCR status using the semiparametric Kaplan-Meier method, with the date of BC diagnosis as the starting point. The study included 1,601 patients, with an average age of 49 years and a majority presenting stage IIIa disease (35%). Most had invasive nonspecial type (NST) BC (94%), and a significant portion (86.7%) exhibited a Ki-67 index <14. The overall pCR rate was 22.7%, with higher frequencies observed in the triple negative and luminal B subtypes. Patients who achieved pCR had significantly higher survival rates (89% alive vs. 61%, P<0.001) and better DFS (90% vs. 66%, P<0.001), except in the luminal A subtype, where pCR did not correlate with improved OS or DFS. These updated real-world data (RWD) from BC patients who underwent NAC in Brazil revealed a pCR rate of 22.7% in all cancer subtypes and stages. pCR was not associated with better outcomes in patients with luminal A, contrasting with other subtypes.

Ferroptosis Inhibition: A Key Opportunity for the Treatment of Ischemia/Reperfusion Injury in Liver Transplantation.

The outcome after liver transplantation has improved in recent years, which can be attributed to superior storage and transportation conditions of the organs, as well as better peri- and postoperative management and advancements in surgical techniques. Nevertheless, there is an increasing discrepancy between the need for organs and their availability. Consequently, the mortality rate on the waiting list is high and continues to rise. One way of counteracting this trend is to increase the use of "expanded criteria donors." This means that more and more donors will be included, especially those who are older and having additional comorbidities (eg, steatosis). A major complication of any transplantation is the occurrence of ischemia/reperfusion injury (IRI), which often leads to liver dysfunction and failure. However, there have been various promising approaches to minimize IRI in recent years, but an effective and clinically applicable method to achieve a better outcome for patients after liver transplantation is still missing. Thereby, the so-called marginal organs are predominantly affected by IRI; thus, it is crucial to develop suitable and effective treatment options for patients. Recently, regulated cell death mechanisms, particularly ferroptosis, have been implicated to play a major role in IRI, including the liver. Therefore, inhibiting this kind of cell death modality presents a promising therapeutic approach for the management of this yet untreatable condition. Thus, this review provides an overview of the role of ferroptosis in liver IRI and transplantation and discusses possible therapeutic solutions based on ferroptosis inhibition to restrain IRI in marginal organs (especially steatosis and donation after circulatory death organs).

Functional Outcome of Volar Barton Fracture of Distal End Radius Undergoing Plating

Background: Volar Barton fractures of the distal radius are complex intra-articular injuries that often require surgical intervention for optimal functional recovery. Volar plating is commonly used to achieve stable fixation and early mobilization.Objective: This study aimed to evaluate the functional outcomes and complications in patients with volar Barton fractures of the distal radius treated with volar plating.Methods: This prospective study was conducted from March 2023 to March 2024, including 60 patients aged 18-60 years with AO/ASIF type B3 volar Barton fractures. All patients underwent open reduction internal fixation (ORIF) using a volar locking plate through a modified Henry approach. Postoperative assessments were performed at six months using Gartland and Werley’s wrist score. Data analysis was conducted using SPSS 25, with one-way ANOVA applied to evaluate associations between variables, considering a p-value &lt; 0.05 as significant.Results: The average age was 34.43 ± 12.34 years. Excellent functional outcomes were achieved in 61.7% of patients, good in 30%, fair in 6.7%, and poor in 1.7%. Complications were minimal, with 95% of patients reporting none, 3.3% experiencing wound infections, and 1.7% reporting wrist stiffness.Conclusion: Volar plating for volar Barton fractures showed excellent to good functional outcomes in most patients, with minimal complications. Further studies with larger populations are recommended.

Impact of diabetes mellitus on endodontic treatment outcomes

Diabetes mellitus (DM) is a chronic metabolic disorder that affects various systemic functions, including oral health. Its impact on endodontic treatment outcomes has become a significant concern for dental practitioners. The relationship between DM and endodontic outcomes is complex, involving several pathophysiological mechanisms. Hyperglycemia leads to the formation of advanced glycation end-products, causing vascular dysfunction and impaired blood supply to the pulp, which exacerbates pulpal inflammation and increases the risk of necrosis. Additionally, chronic low-grade inflammation and an impaired immune response in diabetic patients contribute to a higher susceptibility to infections, delayed healing, and compromised tissue repair after endodontic procedures. Diabetic patients often experience lower success rates and prolonged recovery following endodontic treatment due to these systemic challenges. Reduced bone healing, persistent periapical lesions, and altered microbial flora are common complications that can hinder treatment success. Effective management of endodontic treatment in diabetic patients requires a multifaceted approach that includes strict glycemic control, the use of enhanced antimicrobial strategies, and the adoption of minimally invasive techniques to reduce tissue trauma. Additionally, patient education and close monitoring of the healing process are essential for minimizing complications. Understanding the pathophysiological interactions between diabetes and pulpal inflammation, as well as the factors that influence healing and success rates, is crucial for optimizing endodontic care in diabetic patients. By addressing both systemic and local factors, dental practitioners can improve the prognosis of endodontic treatment and ensure better outcomes for patients with diabetes. Ongoing research into the mechanisms underlying these complications will further enhance the ability of clinicians to manage endodontic cases effectively in this growing patient population.

Anterior Cruciate Ligament Reconstruction Utilizing Double Adjustable-Loop Suspensory Fixation Devices Provides Good Clinical Outcomes in Patients under the Age of 40 Years at Two-Year Follow-Up.

Background: Anterior cruciate ligament reconstruction (ACLR) using double adjustable fixation gained popularity in the last decade due to its minimally invasive technique. However, suspensory fixation devices could be related to recurrent instability, poor clinical outcomes, and patient dissatisfaction. The present study aims to evaluate the clinical outcomes following ACLR using double adjustable-loop suspensory fixation devices in the demanding population of young patients. Methods: Between 2019 and 2022, 95 patients with knee post-traumatic anterior cruciate ligament insufficiency were treated with primary ACLR using semitendinosus quadrupled graft and double adjustable-loop suspensory fixation devices and followed for at least two years. Concomitant lesions were also treated at the same surgical time. The knee examination form of the International Knee Documentation Committee (IKDC) was used to assess clinical evaluation, and the return to physical activities using the Tegner Activity Scale was recorded. Patient-reported objective measures (PROMs) were also evaluated, including the IKDC subjective and Lysholm scores. Results: Sixty-six males and twenty-nine females with a mean age of 23.8 (range 18-37) and a mean BMI of 24.9 (SD ± 2.42) kg/m2 were included in this study. All patients were evaluated clinically as normal or nearly normal at the final follow-up. PROMs also significantly improved postoperatively (p < 0.05) compared to the preoperative values. The Tegner Activity Scale increased from 2 to 7, the IKDC mean score improved from 43.9 (±8.9) to 93.3 (±12.3), and the modified Lysholm from 47.3 (±11.1) to 92.9 (±16.6). No complications or adverse events were recorded. Conclusions: Anterior cruciate ligament reconstruction utilizing double adjustable-loop suspensory fixation devices provides good clinical and functional outcomes in young patients at a two-year follow-up.

Factors affecting neurological outcomes of patients with sudden cardiac arrest in the emergency department

BackgroundLittle is known about patients with sudden cardiac arrest in the emergency department (ED). This study aimed to identify factors affecting the prognosis of patients with cardiac arrest in the ED.MethodsThis retrospective study analyzed patients with sudden cardiac arrest admitted to the ED of a general hospital between January 2016 and July 2020. A total of 153 patients with sudden cardiac arrest were identified, and 149 patients for whom all data could be confirmed were included in the statistical analysis of this study. A good neurological outcome was defined as a Cerebral Performance Category (CPC) scale score of 1 or 2, assessed 6 months after discharge.ResultsIn the univariate analysis, the characteristics of patients included in the good neurological outcomes group were younger (t = 3.553, p < .001), had shorter low flow time (t = 3.31, p = .019), and had more shockable initial rhythms (χ2 = 28.038, p = < .001). As a result of multivariate binary logistic regression analysis, among 43 patients alive 6 months after discharge, age 60 years or younger (odds ratio = 32.703, p = .005), low flow time 6 min or less (odds ratio = 38.418, p = .006), and initial shockable rhythm (odds ratio = 31.214, p < .001) were identified as predictors that had a significant impact on good neurological outcomes.ConclusionsYoung age, short low-flow-time, and initial shockable rhythm are predictors of good neurological outcomes in patients with acute cardiac arrest in the ED.

The causal relationship between CSF metabolites and GBM: a two-sample mendelian randomization analysis

BackgroundGlioblastoma multiforme (GBM) is a highly aggressive primary malignant brain tumor characterized by rapid progression, poor prognosis, and high mortality rates. Understanding the relationship between cerebrospinal fluid (CSF) metabolites and GBM is crucial for identifying potential biomarkers and pathways involved in the pathogenesis of this devastating disease.MethodsIn this study, Mendelian randomization (MR) analysis was employed to investigate the causal relationship between 338 CSF metabolites and GBM. The data for metabolites were obtained from a genome-wide association study summary dataset based on 291 individuals, and the GBM data was derived from FinnGen included 91 cases and 174,006 controls of European descent. The Inverse Variance Weighted method was utilized to estimate the causal effects. Supplementary comprehensive assessments of causal effects between CSF metabolites and GBM were conducted using MR-Egger regression, Weighted Median, Simple Mode, and Weighted Mode methods. Additionally, tests for heterogeneity and pleiotropy were performed.ResultsThrough MR analysis, a total of 12 identified metabolites and 2 with unknown chemical properties were found to have a causal relationship with GBM. 1-palmitoyl-2-stearoyl-gpc (16:0/18:0), 7-alpha-hydroxy-3-oxo-4-cholestenoate, Alpha-tocopherol, Behenoyl sphingomyelin (d18:1/22:0), Cysteinylglycine, Maleate, Uracil, Valine, X-12,101, X-12,104 and Butyrate (4:0) are associated with an increased risk of GBM. N1-methylinosine, Stachydrine and Succinylcarnitine (c4-dc) are associated with decreased GBM risk.ConclusionIn conclusion, this study sheds light on the intricate interplay between CSF metabolites and GBM, offering novel perspectives on disease mechanisms and potential treatment avenues. By elucidating the role of CSF metabolites in GBM pathogenesis, this research contributes to the advancement of diagnostic capabilities and targeted therapeutic interventions for this aggressive brain tumor. Further exploration of these findings may lead to improved management strategies and better outcomes for patients with GBM.

SP9.5 - Peri-operative Comprehensive Geriatric Assessment (CGA): A new benchmark for Acute General Surgery patients

Abstract Aims More than 50% of patients undergoing emergency general surgery are over 65 years of age. NICE guidelines emphasise frailty assessment in acute surgical settings, particularly in the preoperative period. Similarly, the Emergency Laparotomy and Frailty (ELF) study showed associations between frailty (CFS ≥ 5) and 90-day mortality, increased complication and length of hospital stay in older emergency laparotomy patients. NELA best practice tariff (BPT) April 2023 heavily focuses on perioperative team involvement in frailer, older patients. This is an audit from a city teaching hospital, with a surgical liaison team against standards set by NELA. Methods Review of patients aged ≥ 65 undergoing emergency laparotomies between August and November 2023 (pre-intervention) then December and January 2024 (post-intervention). Data collected includes whether patients had a documented frailty score, a clearly documented CPR decision &amp; treatment escalation plan (TEP), pre- or post-operative medical review, and advanced-care planning (ACP) post-operatively. Intervention included dedicated members of surgical liaison team following patients throughout admission, weekly meetings to discuss laparotomy patients, older patient template being created capturing ceilings of care, frailty score, and social history. Results Post intervention, improvement in clear documentation regarding escalation, frailty level. Greater level of MDT collaboration with regards to older patients undergoing laparotomies. Conclusion Changes in NELA BPT emphasise the importance of comprehensive geriatric assessment in the management of older laparotomy patients. Even a basic surgical liaison service can achieve high levels of compliance with a few simple strategies, resulting in better outcomes for patients as well as financial benefits for Trusts.

Open Reduction in Traumatic Cervical Facet Dislocation Does Not Delay Time to Treatment.

Background Cervical facet dislocation is a serious injury that can result in permanent neurologic damage. Current guidelines recommend immediate closed reduction of cervical dislocations, though the efficacy of this practice remains a debate. This study aims to evaluate whether immediate open reduction and fixation of cervical dislocations offer equal or better outcomes for patients and limit the need for follow-up operations. Methods This is a retrospective study including patients who presented to the emergency department of a single institution from 2008 to 2023 with cervical facet dislocation. Patients were divided into groups based on initial treatment: either open or closed reduction. Time to surgery was calculated as the time between arrival to the ED and incision time in the OR. Primary outcomes were improvement in motor and sensory deficits at six-week post-operative follow-up. Results There were 31 patients who met the inclusion criteria. Time to treatment did not differ significantly between the open versus closed reduction groups. There were no differences between groups in improvement in motor function, sensory function, or pain at the six-week follow-up. All patients treated with initial closed reduction ultimately required surgical stabilization. Conclusions Open reduction as a first-line treatment did not increase the time to treatment for patients with cervical facet dislocations. Patients had equivalent functional outcomes in both treatment groups. The findings suggest that current practice guidelines may delay definitive treatment without improving patient safety or outcomes.

Barriers to Nurse-Patient Communication at Primary Health Centers in Almadina Munawara City, Saudi Arabia

Background: Nurse-patient communication is a unique clinical skill in the healthcare professions that promotes good quality care and patient outcomes. This communication can be disrupted by many barriers that impact the therapeutic relationship and deliver of care. Purpose: The study aims to identify the barriers affecting nurse-patient communication at primary health centers in Almadina Munawara City, Saudi Arabia. Methods: A cross-sectional study was performed among 212 nurses and 214 patients utilizing a self-reporting questionnaire. A version of the same file was then uploaded into NVivo, and data that were coded under all communication barriers including language discordance among patients and healthcare providers (e. g., subtheme: patient prefers a mother tongue speaking doctor), cultural-religious difference and environmental cues between the involved parties to determine their importance in this context as well (see Table 2). Results: The results showed that language, cultural and environmental differences had an extensive influence on how nurses communicated with patients. Key barriers included nurse shortages, limited communication time and low income. Our results suggest that these barriers differ in their effect with language barrier and habitat disturbance being the most important ones. Conclusions: This study concludes that nurse-patient communication is a complex multi-sectional process, constrained by numerous barriers. Strategic intervention aimed at addressing these barriers can strengthen nurse-patient interaction and accelerate patient care. Communication remains a cornerstone in all the best practices of delivering healthcare effectively and keeping patients happy.
