Nephrology intervention to avoid acute kidney injury in patients awaiting cardiac surgery: randomized clinical trial

IntroductionCardiac surgery-associated acute kidney injury (CSA-AKI) is a well-known complication that increases morbidity and mortality rates. The objective of this study was to reduce CSA-AKI through nephrologist intervention in patients awaiting cardiac surgery.MethodsWe performed a single center, open-label, randomized clinical trial including 380 patients who underwent scheduled cardiac surgery at the Hospital de Bellvitge between July 2015 and October 2019. A total of 184 patients were evaluated by the same Nephrologist one month before the surgery to minimize the risk factors for AKI. In addition to assessments at the outpatient clinic, we also collected clinical data during hospitalization and during the first year.ResultsDespite the intervention, no differences were observed between the groups in the incidence of CSA-AKI (intervention group 26.37% vs. standard of care 25.13%, p=0.874), mortality (3.91% vs. 3.59%, p=0.999), length of Intensive Care Unit (ICU) stay (10 days [7.00;15.0] for both groups, p=0.347), or renal function after one year of follow-up (estimated glomerular filtration rate (eGFR) by CKD-EPI: 74.5 ml/min (standard deviation 20.6) vs 76.7 (20.8) ml/min, respectively, p=0.364). A reduction in the need for blood transfusion was observed in the intervention group, although the difference was not statistically significant (37.22% vs. 45.03%, p =0.155).ConclusionIn this clinical trial, nephrologist intervention in the entire population on the cardiac surgery waiting list did not show a nephroprotective benefit.Clinical trial registrationClinicalTrials.gov, identifier (NCT02643745).

BN SO20 - Day-case laparoscopic cholecystectomy: Predictors of failure

Abstract Background Laparoscopic Cholecystectomy (LC) is the main treatment option for symptomatic gallstone disease. It is commonly performed as a day case operation and Getting It Right First Time (GIRFT) have suggested that this should be the default position for all trusts. NHSE Model Hospital analyses hospital metrics and sets national benchmarks. They suggest that the day case rate for LC should be greater than 71.4%. The aim of our study is to analyse all elective LC’s over a two year period and identify factors that increase the likelihood of day-case failure and the common reasons for this. Method All patients who had LC between 1st July 2020 and 30th June 2022 were identified. All emergency cholecystectomies were excluded from analysis. Patient and operative details were retrieved from their electronic record and a Charlson co-morbidity index was calculated. Statistical analysis was performed using SPSS with Chi-squared tests performed for categorical data and ANOVA for continuous data. Odds ratios with 95% confidence intervals were calculated. Statistical significance was taken as p<0.05. Results 788 patients had elective cholecystectomies with 74.0% being successful day-case. Factors increasing day-case failure included: Admission with gallbladder disease within past year (OR 3.15 (2.26-4.37), CBD diameter>8mm (OR 2.17(1.44-3.26), thick-walled gallbladder (OR 2.20(1.59-3.04), on-table cholangiogram (OR 4.16 (2.21-7.84), sub-total cholecystectomy (OR 30.6(9.19-102) and male sex (OR 1.55(1.11-2.18). Patients who failed day-case had higher mean age (59 vs 49) and higher co-morbidity index (2.16 vs 1.44). The most common reasons for day-case failure were complex procedure (41%), and symptom control (35%). Only 20% had planned admissions. 30-day morbidity and re-admission rate were higher for failed day-case patients. Conclusion Our hospital complies with the day case benchmark set out by Model Hospital. Furthermore, only 5.2% of patients undergoing elective cholecystectomy had a pre-operative decision for an inpatient stay demonstrating that day case is the default for the vast majority of patients. Despite this, improvement could still be made with post-operative symptom control to try and increase this number further.

HPB SO01 - Preoperative respiratory disease and outcomes of pancreatoduodenectomy performed for malignancy

Abstract Background Despite improvements to morbidity and mortality rates in recent decades, pancreatoduodenectomy (PD) remains a high-risk operation. Patients with pre-existing respiratory disease are likely to be at increased risk of developing postoperative complications but few prior studies have investigated this. This may be as few patients with significant respiratory pathology are considered appropriate surgical candidates. This study aimed to compare PD outcomes in patients with a prior respiratory condition to those without. The outcomes of interest were median length of stay (LOS), 30-day readmission, 90-day mortality, unplanned return to theatre rate and five-year survival. Method Data was extracted from the Recurrence After Whipple’s (RAW) study, a multicentre retrospective cohort study of outcomes of PD performed for pancreatic head malignancy (29 centres in 8 countries, n=1484). Pre-existing respiratory disease included a prior diagnosis of asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, pulmonary embolism, asbestosis, obstructive sleep apnoea, pleural effusion, tuberculosis, pulmonary sarcoidosis, pneumoconiosis or hypersensitivity pneumonitis. The Mann-Whitney U test and Fisher exact test were used to compare the two groups. Results Out of a total of 1484 cases, 142 patients (9.6%) had a pre-existing respiratory comorbidity. Asthma and COPD both affected 4.2% of patients. All other included pathologies affected less than one percent of patients. 30-day readmission (8.5% vs 9.1%, p=0.1), 90-day mortality (1.4% vs 3.7%, p=0.2), and unplanned return to theatre rate (3.5% vs 5.1%, p=0.5) were similar between the two groups, however, median LOS was significantly longer in those with a prior respiratory disease (14 vs 13 days, p<0.0001). Five-year survival was also higher in those without respiratory disease, but this was not quite significant (24.6% vs 32.5%, p=0.06). Conclusion In our multicentre study of patients with confirmed malignancy, PD patients with a preoperative respiratory disease had significantly longer length of stay. Five-year survival rates were slightly lower but this was not quite significant.

BN SO42 - Our experience of Emergency Laparoscopic Fundoplication in a DGH

Abstract Background Emergency presentation of hiatal hernias can be life-threatening and is associated with high morbidity and mortality rates. Elective Laparoscopic hiatus and paraoesophageal hernias are commonly performed with fundoplication. However, emergency cases are often repaired without an anti-reflux procedure. We present our experience of emergency Laparoscopic Hiatus/ Paraoesophageal hernia repair with fundoplication in a District General Hospital (Russells Hall Hospital, RHH). Method 6 cases of diagnosed hiatus/ paraoesophageal hernia that underwent Emergency fundoplication from 2019-2024. Results The mean age of the patients was 74 (56-83). All patients had a pre-op CT scan to confirm the diagnosis. 4 patients (66%) had a Type 3 Hiatus hernia and 2 (33%) had a Type 2 classic paraosephageal hernia. All patients underwent Emergency Laparoscopic Hiatus / Para oesophagal hernia repair with fundoplication. 2 patients required mesh for the repair. The mean length of stay was 5 days (3-7). There were no intra or post-op complications and on follow up 1 patient had a recurrence of symptoms after 1 year requiring redo fundoplication. Conclusion The choice of operation is mainly based on the patient’s clinical condition, the complexity of the hernia and the surgeon’s experience. Our experience at RHH shows that Laparoscopic Hiatus/ Paraoesophageal hernia repair with fundoplication is safe and feasible in patients with emergency presentation.

EGS SO25 - Ingestion of Sharp Foreign Bodies- Emerging Trends in a Large UK NHS Trust

Abstract Background Foreign body (FB) ingestion is a common medical problem. The type of object ingested depends on age, sex, socio-economic factors, geographical area, and nutritional habits. Accidental ingestion of hijab pins as a phenomenon has not been widely reported in the UK previously. Method Retrospective cohort study on all patients presenting with foreign body ingestion from July 2010 to January 2024. Patient medical records were reviewed, and data collected including mode of presentation, demographics, FB type and mode of ingestion (accidental/deliberate), admission details, radiology, management (conservative, endoscopic, surgery), morbidity and mortality and readmission rate. Data was recorded and analyzed using Microsoft Excel. Results 94 patients presented with FB ingestion of whom 39 ingested hijab pins. Median age was 19 (11-50) years. Median time from ingestion to presentation was 5 hours (0.5-120). All patients had abdominal Xray. The most common hijab pin location on presentation was in the stomach; n=27 (69%). Data on management was available in 38 patients, of whom 29 (76%) were managed conservatively, 6 (15%) had endoscopy and 3 (8%) had flexible nasal endoscopy (FNE). The reintervention rate was 3% with one patient managed conservatively subsequently having endoscopy. No complications, readmissions or mortality was observed. One OGD was therapeutic Conclusion We report increase in the incidence of FB ingestion with a significant proportion involving hijab pins. Young girls hold pins between their lips while styling their hijabs which can result in accidental ingestion. Although we report low morbidity and readmission rates, there is a 22% intervention rate. We believe there may be a causal link between increased accidental ingestion and popularity of social media content on elaborate hijab styling, some with millions of views each. There is a need to increase awareness on dangers of holding pins in the mouth whilst styling hijabs and alternate options such as hijab magnets

BS SO06 - Bariatric Surgery is a Safe, Effective and Feasible Option in Super-Super Obese Patients

Abstract Background Bariatric surgery is proven to be feasible and safe in obese and super obese patients (BMI < 60). SSO patients pose greater challenges from technical and medical standpoints. This cohort study aims to assess the safety and feasibility of bariatric surgery in SSO individuals. Method A retrospective analysis of a prospective database was conducted, encompassing 4471 bariatric procedures performed over seven years (January 2016 to December 2023). Fifty patients were classified as SSO (BMI > 65). Key outcome variables examined included length of stay (LOS), intra-operative complications, and 30-day morbidity and mortality rates. We evaluated the Resolution of Obesity Related Morbidity (RORM). Results Sleeve gastrectomy most common procedure (24, 48%), followed by One Anastomosis Gastric Bypass (17, 34%). Six patients underwent Roux-en-Y Bypass (12%), and six others received SADIs (12%). Among these, [24 (48%)] had obstructive sleep apnea (OSA), [14 (28%)] had diabetes mellitus (DM) and [9 (18%)] had hypertension. Average LOS was 2.5 days. No mortality was reported within 30 days with no intra-operative complications. One patient required readmission to the hospital within 30 days after discharge due to vomiting. The report at 6 months was positive. OSA, DM and Hypertension were resolved in [11 (46%), 13 (92%) and 7 (77%)] Conclusion Bariatric surgery should not be dismissed for SSO patients solely due to perceived increased risk based on BMI. Evidence suggests that it can be safely performed on SSO individuals, yielding significant benefits particularly for obesity-related morbidity.

HPB SO16 - The accuracy of various diagnostic methods in differentiating between malignant and benign hilar strictures - a systematic review

Abstract Background It is difficult to distinguish benign and malignant hilar strictures and surgical resection is associated with high rates of morbidity and mortality. Therefore, more accurate diagnostic methods are required. The aim of this systematic review was to investigate the sensitivity and specificity of current diagnostic strategies in differentiating between malignant and benign hilar strictures. Method This systematic review was conducted in line with the PRISMA guidelines. A comprehensive literature search was completed using PUBMED and Medline databases to identify original research studies reporting sensitivity and specificity of various diagnostic methods for hilar strictures. Results A total of 653 papers were identified and after review 20 publications were included in the analysis, comprising 1,824 patients. (18)F-FDG PET/CT appeared in 6 studies with sensitivity range 69.6%-92.3%, followed by cytology identified in 5 studies with sensitivity 32.9%-89% and specificity 89%-100%. Finally, CEA marker was utilized in 3 studies with sensitivity 33%-72% and specificity 84%-90%. Conclusion Due to wide variation in reported accuracy of diagnostic tests in suspected hilar CCA, a prospective observational study is warranted to determine the optimal strategy and understand the current error rate and where improvements may be made.

Clinical characteristics and prognosis analysis of pseudomonas aeruginosa bloodstream infection in adults: a retrospective study.

Pseudomonas aeruginosa bloodstream infections (PA BSIs) in adults, especially those complicated by sepsis, are associated with high rates of morbidity and mortality. Early identification of risk factors for both mortality and sepsis-induced coagulopathy (SIC) is critical to optimizing patient management and improving outcomes. We conducted a retrospective analysis of 118 adult patients diagnosed with PA BSIs at the Affiliated Hospital of Xuzhou Medical University from January 2022 to February 2024. Univariate analysis was employed to identify significant clinical factors, followed by multivariate stepwise logistic regression to determine independent predictors of mortality and SIC. Based on these findings, nomogram models were constructed and evaluated using the area under the receiver operating characteristic curve (AUC), Bootstrap resampling, and calibration plots to assess model performance. Empiric sensitive antibiotic therapy (ESAT) (OR = 0.039, P < 0.001), coronary artery disease (CAD) (OR = 10.315, P = 0.010), and invasive mechanical ventilation (OR = 3.926, P = 0.020) emerged as significant predictors of mortality. In contrast, elevated C-reactive protein (CRP) (OR = 1.011, P = 0.003), procalcitonin (PCT) (OR = 1.030, P = 0.005), and lower hemoglobin levels (OR = 0.963, P = 0.004) were independently associated with SIC. The AUC of mortality prediction model is 0.908, while the SIC prediction model yielded an AUC of 0.817. The predictive models developed in this study demonstrate early identification of mortality rates and SIC risk in PA BSI patients, which may have the potential to guide timely therapeutic interventions and improve clinical outcomes in this high-risk population.

HPB SO58 - Reporting outcomes on the management of complex benign biliary pathology referred into a tertiary Hepatobiliary centre

Abstract Background Gallstone disease represents a significant portion of acute general surgery workload. Complex biliary pathology is a common cause of referrals to tertiary hepatobiliary (HPB) centres, however, there is a paucity in the literature regarding criteria for referrals and the outcomes from the management of these cases. The aim of this study was to report the outcomes of patients referred to a tertiary HPB centre in an acute setting from secondary care hospitals for management of benign biliary pathology. Method Patients who were transferred to the HPB unit at Manchester Royal Infirmary from secondary care hospitals in the North West of England between September 2022 and May 2024 for benign biliary pathology were included. Patients were identified from the electronic emergency transfer centre. Data was collected on the reason for referral and management at the HPB unit. Outcomes were reported as: admission to intensive care (ITU), length of stay in hospital, in-hospital mortality, Clavien-Dindo grading of surgical complications and re-admission to hospital. Data was retrospectively collected from electronic patient records. Results Twenty-three patients were included. The most common reasons for transfer included: biliary drainage for choledocholithiasis where endoscopic retrograde cholangiopancreatography (ERCP) was not feasible at the referring hospital (8/23); Mirizzi syndrome (4/23); emergency general surgery not offered at the referring hospital (3/23) and perforated gallbladder (2/23). Ten patients were managed surgically, five patients had ERCPs, four patients had radiological interventions and four were managed conservatively. Two patients were admitted to ITU, one patient died within admission and a second patient managed conservatively was re-admitted within 30 days. Post-operative morbidity rate was 30%. The median hospital stay was 12 days (2, 50). Conclusion Our data demonstrates that complex biliary pathology that has been referred into a tertiary HPB unit from secondary care hospitals has been managed safely, with low rates of morbidity and mortality. Patients who underwent cholecystectomies that were deemed to be high risk had a 0% mortality rate. This study adds to the body of evidence that centralisation of specialist services with a multi-disciplinary approach has led to better patient outcomes.

EGS SO24 - Endoscopic Vacuum Therapy for Oesophageal Perforation and Anastomotic Leaks

Abstract Background Oesophageal perforations and oesophago-gastric (OG) anastomotic leaks are challenging conditions, associated with significant morbidity and mortality. In recent years, endoscopic vacuum (EndoVac) therapy has emerged as a novel, alternative intervention for source control and to promote healing. Introduced to our unit in 2019, this cohort study presents our experience with EndoVac management of both post operative OG anastomotic leaks and primary oesophageal ruptures. Method Retrospective analysis of patient electronic records was conducted for all patients who received EndoVac management between the study period of October 2019 to June 2023. Pertinent outcome variables included length of vacuum therapy, number of changes, length of admission, in hospital and 90 day mortality rates. Results 37 patients were identified within the study period. The average age of this study cohort was 68 years with a mode ASA of III. The most common indication for EndoVac therapy was anastomotic leak (56%), followed by oesophageal perforation (31%). Defect resolution was achieved in 72% of patients. The median duration of treatment was 26 days (range 2-157), whilst the median number of changes was 7 (range 2-31). The overall in hospital complication (Clavien Dindo I-V) rate was 34%. The 90-day mortality rate was 22% whilst the morbidity rate was 13% in the form of anastomotic stricturing requiring serial dilatations. Conclusion EndoVac therapy is an effective minimally invasive treatment for post operative OG anastomotic leaks and oesophageal ruptures. With ongoing expansion in it’s use in our unit and throughout the UK, further work is required to assess the long-term outcomes and develop guidelines around its use in both oesophageal leaks and perorations.

ArtiSentialⓇ versus conventional laparoscopic colorectal cancer surgery: a multicenter retrospective matched cohort study

Background: This study aims to compare outcomes of colorectal cancer surgeries performed using the newly developed articulating laparoscopic instrument, ArtiSential®, with those using conventional non-articulating or rigid laparoscopic instruments. Methods: This multicenter, retrospective, matched cohort study enrolled patients with colorectal cancer undergoing laparoscopic surgery in seven tertiary referral hospitals from January 2021 to October 2022. A 1:1 propensity score matching was performed between the articulating (Arti-LAP) and conventional (Rigid-LAP) laparoscopic groups. The primary outcome was the overall incidence of short-term complications. Results: The study initially comprised 694 and 2008 patients in the Arti-LAP and Rigid-LAP groups, respectively. After matching, each group consisted of 694 patients, with no significant differences in baseline clinical characteristics. Mean operation time was 161 ± 32 min in Arti-LAP and 152 ± 25 min in Rigid-LAP groups (P=0.105). Open conversion rates were 0% (0/694) in Arti-LAP and 1.0% (7/694) in Rigid-LAP groups (P=0.024). Overall morbidity rates were 9.5% (66/694) in Arti-LAP and 12.8% (89/694) in Rigid-LAP (P=0.061), with similar rates of severe morbidities. Specimen quality was acceptable in both groups. Multivariable regression analysis showed that the choice of instrument type (articulating or rigid) was not associated with perioperative morbidity. Despite a short median follow-up period of 19.5 months, no significant difference in disease-free survival was observed between the groups. Conclusion: Laparoscopic surgery using ArtiSential® was performed safely and effectively for patients with colorectal cancer. Articulating laparoscopic instruments may offer an advantage in reducing open conversion rates.

Abstract 4138433: Prevalence, Clinical Characteristics, and Outcomes in Heart Failure with Improved Ejection Fraction by Chronological Age

Background: HF incidence increases with age. Modern treatments have led to more patients recovering LVEF, classified as HF with improved ejection fraction (HFimpEF). However, the age-related epidemiology and prognosis of HFimpEF remain unclear. Hypothesis: Compared to younger patients, older patients will have lower rates of HFimpEF after incident HFrEF and higher rates of HF-related morbidity and mortality. Aims: To describe the clinical characteristics and outcomes in HFimpEF across the age spectrum within a healthcare delivery system in the US. Methods: We identified adults ≥18 years with incident HFrEF (LVEF≤40%) between 2013-2018 within Kaiser Permanente Northern California (KPNC), a healthcare system serving 4.5 million members. HFimpEF was defined as baseline LVEF &lt;40% with subsequent &gt;10% improvement to &gt;40%. HFimpEF incidence was assessed by baseline age categories (&lt;50, 50-64, 65-79, ≥80 years [yrs]). Rates of worsening HF (WHF) events (i.e. HF-related hospitalization, ED, or outpatient visits) were compared between HFimpEF and persistent HFrEF patients across age using Cox proportional hazards models adjusted for sex and EF at the time of incident HFrEF, including potential interaction by age modeled continuously (cubic splines with 3 knots). Data: Among 12,639 adults with incident HFrEF, 33% experienced HFimpEF, with lower rates at older ages: 42% (&lt;50 yrs), 41% (50-64 yrs), 35% (65-79 yrs) and 18% (≥80 yrs). Among patients with HFimpEF alive at 1-year post-HFrEF (N=9954), WHF incidence (per 100 p-y) remained high (10.7) in younger (&lt;50 yrs) patients and increased by age: 14.5 (50-64 yrs), 21.6 (65-79 yrs), and 33.7 (≥80 yrs)(P &lt;0.001 for trend; Figure, Panel A). Patients with HFimpEF, compared to those with persistent HFrEF, had lower adjusted rates of WHF across the spectrum of age (pinteraction by age &lt; 0.001; Figure, Panel B). Conclusion: HFimpEF is common within a year of incident HFrEF, more prevalent in younger patients, and is associated with significant residual clinical risk. Compared to persistent HFrEF, improvements in LVEF are associated with a lower risk of WHF or death. Additional research is needed to understand HF symptom burden and medical therapy use in this population.

Domains of four-step technique training program for laparoscopic colorectal surgery.

Many surgeons have begun learning about colorectal surgery using laparoscopy rather than laparotomy. The domains of four-step technique training program (DOF) for laparoscopic colorectal surgery have been designed and implemented by our institute since 2011, and they are expected to provide a safe and effective program for trainees with limited experience in laparoscopic colorectal surgery. The DOF were established with standard surgical procedures, a four-step technique, and learning passports using point credits after the procedure was completed. Patients who underwent minimally invasive colorectal resection at the Chang Gung Memorial Hospital between January 2013 and April 2019 were enrolled. Overall, 2604 and 478 patients were enrolled in the non-training and training groups, respectively. Multivariable logistic regression analysis revealed that the postoperative short-term outcomes were not significantly associated with the training or non-training groups. However, the training group had a significantly longer operative time than the non-training group in the linear regression model. Once the trainee passed the proficiency point (passed 100 points or 30 cases), no significant difference in postoperative short-term outcomes was found between the patients in the non-training and training groups that underwent the entire surgery performed by the trainee. When patients' safety was evaluated in the training cases under the DOF, no higher rates of postoperative morbidity and mortality were found compared to those in cases performed by experienced surgeons. Additionally, trainees who passed the proficiency point during DOF could safely perform the entire laparoscopic colorectal surgery under supervision without further adverse effects on the patients.

Esophageal adenocarcinoma models: a closer look

Esophageal adenocarcinoma (EAC) is a subtype of esophageal cancer with significant morbidity and mortality rates worldwide. Despite advancements in tumor models, the underlying cellular and molecular mechanisms driving EAC pathogenesis are still poorly understood. Therefore, gaining insights into these mechanisms is crucial for improving patient outcomes. Researchers have developed various models to better understand EAC and evaluate clinical management strategies. However, no single model fully recapitulates the complexity of EAC. Emerging technologies, such as patient-derived organoids and immune-competent mouse models, hold promise for personalized EAC research and drug development. In this review, we shed light on the various models for studying EAC and discuss their advantages and limitations.

Laparoscopic cholecystectomy emerges as the preferred approach, demonstrating lower complication rates when performed in specialized centers. The discussion contextualizes these findings within the theoretical framework, considering the study's limitations. Implications of the Research: The practical implications suggest the necessity for a multidisciplinary team and careful risk assessment, emphasizing the adoption of minimally invasive surgical techniques and stringent control of ascites to enhance clinical outcomes. Originality/Value: This study contributes to the literature by highlighting the complexity of surgical management in cirrhotic patients and the importance of specific strategies. The relevance of this research is underscored by the need for the development of less invasive techniques and a better understanding of the specific complications faced by these patients.

Evaluation of Procalcitonin in Type-2 Diabetes Mellitus Patients in Minahasa, North Sulawesi, Indonesia

Diabetes mellitus (DM) remains a significant global health challenge, contributing to high morbidity and mortality rates. In Indonesia, type 2 diabetes is increasing, with a substantial percentage of patients experiencing poor glycemic control. This study aims to explore the relationship between serum procalcitonin levels and fasting blood glucose (FBG) in patients with type 2 diabetes, assessing procalcitonin&amp;apos;s potential as a biomarker for diabetes complications. A total of 122 patients with confirmed type 2 diabetes were included, excluding those with infection or recent trauma. Clinical parameters, including blood pressures, body mass index (BMI), and blood samples for FBG and procalcitonin levels, were collected. Statistical analysis was performed using SPSS version 26.0. The mean age of participants was 56.7 years, with 43.4% diagnosed with hypertension. A significant correlation was found between procalcitonin and FBG (&amp;lt;i&amp;gt;p&amp;lt;/i&amp;gt; = 0.024, r = 0.205), indicating a weak positive relationship. No significant differences in procalcitonin levels were observed between hypertensive and non-hypertensive patients. The findings suggest that procalcitonin may serve as a useful biomarker in managing complications associated with type 2 diabetes. While the correlation with FBG was weak, the role of inflammation in diabetes progression highlights the need for further investigation. Integrating procalcitonin testing into clinical practice could enhance patient management, and future research should explore the mechanisms linking procalcitonin levels to diabetes complications, as well as establish reference values for procalcitonin in diabetic populations.

Abstract 4137965: D-dimer as a 5-year predictor of death in females admitted with chestpain of suspected coronary origin surpasses that of males.

Background: D-dimer (DD) and fibrin monomer (FM) are endstage markers of activated coagulation and reflect prothrombotic states, and α2-antiplasmin (SERPINF2 -SF2) is the main inhibitor of fibrinolysis at the level of plasmin. Women may experience a higher rate of morbidity and mortality compared to men following a myocardial infarction (MI). We present the prognostic potential of DD, FM and SF2 in females as compared to males during 5 years follow-up in a population admitted with chest pain of suspected coronary origin. Methods: A total of 871 consecutive patients with a median age of 72.6 years (females 77.3, males 69.1) were admitted in the study. Of these, 386 were diagnosed with an acute MI based on Troponin-T (TnT) levels &gt;50 ng/L. Stepwise Cox regression models, applying normalized continuous log e /SD values, were fitted for the biomarkers with total mortality within 5 years as the dependent variable. Results: Death was recorded in 246 patients; 34.4% females vs. 27.2% males (Chi-squared test p-value = 0.02). Blood samples were available for analysis of DD, FM and SF2 in 820, 810 and 846 patients, respectively. Females had a signficantly higher mean of DD (p&lt;0.0001) and FM (p=0.0020) than males and SF2 did not differ (p=0.0825). In the univariate analysis, a highly significant association between DD and total death was observed in both sexes (p&lt;0.001). However, after adjusting for confounders in the multivariable analysis, the associations remained significant in females but not in males, with an HR of 1.62 (95%CI 1.36 – 1.93), p&lt;0.0001 vs. 1.16 (95%CI 0.98 - 1.39, p=0.094, respectively, (p for interaction &lt;0.001). Similar findings were noted in the multivariable analysis of FM with HR 1.46 (95%CI 1.19 – 1.80), p=0.0003 in females vs. 1.12 (95%CI 0.93 -1.35), p=0.22 in males (p for interaction 0.056). In the univariate analysis, SF2 was not associated with all-cause mortality; p=0.56 in females vs. p=0.83 in males, and remained essentially unchanged after adjustment; p=0.84 vs. HR 0.92 (95%CI 0.78 – 1.09). p=0.35 in males, yielding a p=0.36 for interaction. Conclusion: Activated endstage coagulation was associated with total death at 5 years FU in females admitted with chest pain of suspected coronary origin, whereas plasmin inhibition was not. A significant p-value for interaction between the two sexes indicates that the prognostic value of DD surpasses that of men.

Differential Replication and Oncolytic Effects of Zika Virus in Aggressive CNS Tumor Cells: Insights from Organoid and Tumoroid Models

Central nervous system (CNS) cancers are responsible for high rates of morbidity and mortality worldwide. Malignant CNS tumors such as adult Glioblastoma (GBM) and pediatric embryonal CNS tumors such as medulloblastoma (MED) and atypical teratoid rhabdoid tumors (ATRT) present relevant therapeutic challenges due to the lack of response to classic treatment regimens with radio and chemotherapy. Recent findings on the Zika virus’ (ZIKV) ability to infect and kill CNS neoplastic cells draw attention to the virus’ oncolytic potential. Studies demonstrating the safety of using ZIKV for treating malignant CNS tumors, enabling the translation of this approach to clinical trials, are scarce in the literature. Here we developed a co-culture model of mature human cerebral organoids assembled with GBM, MED or ATRT tumor cells and used these assembloids to test ZIKV oncolytic effect, replication potential and preferential targeting between normal and cancer cells. Our hybrid co-culture models allowed the tracking of tumor cell growth and invasion in cerebral organoids. ZIKV replication and ensuing accumulation in the culture medium was higher in organoids co-cultured with tumor cells than in isolated control organoids without tumor cells. ZIKV infection led to a significant reduction in tumor cell proportion in organoids with GBM and MED cells, but not with ATRT. Tumoroids (3D cultures of tumor cells alone) were efficiently infected by ZIKV. Interestingly, ZIKV rapidly replicated in GBM, MED, and ATRT tumoroids reaching significantly higher viral RNA accumulation levels than co-cultures. Moreover, ZIKV infection reduced viable cells number in MED and ATRT tumoroids but not in GBM tumoroids. Altogether, our findings indicate that ZIKV has greater replication rates in aggressive CNS tumor cells than in normal human cells comprising cerebral organoids. However, such higher ZIKV replication in tumor cells does not necessarily parallels oncolytic effects, suggesting cellular intrinsic and extrinsic factors mediating tumor cell death by ZIKV.

DIABETES MELLITUS E SUAS IMPLICAÇÕES RENAIS: UMA REVISÃO BIBLIOGRÁFICA FOCADA NA NEFROPATIA DIABÉTICA E INSUFICIÊNCIA RENAL CRÔNICA

The article explores the renal complications of diabetes mellitus (DM), focusing on diabetic nephropathy (DN) and chronic renal failure (CRF). DN, considered one of the main causes of CRF in the world, results in high rates of morbidity and mortality in diabetic patients. The article addresses the pathophysiology of these diseases, highlighting how chronic hyperglycemia in DM leads to a series of structural and functional changes in the kidneys. Mechanisms such as advanced protein glycation, oxidative stress, activation of inflammatory cytokines, and endothelial dysfunction are central to the progression of DN. In addition to pathophysiology, the article extensively discusses treatments available to slow the progression of DN and prevent CKD. Strict control of glycemic levels, through medication and lifestyle changes, is essential. Furthermore, the use of drugs such as ACE inhibitors and angiotensin II receptor blockers has shown beneficial effects on renal protection. Other emerging treatments include SGLT2 and GLP-1 inhibitors, which demonstrate efficacy in both glycemic control and preservation of renal function. The article concludes that prevention and adequate management of these complications are fundamental to improving patients' quality of life and reducing rates of progression to CKD.
