In-hospital new-onset seizures in patients admitted to the medical intensive care unit:An observational study and algorithmic approach

BACKGROUND Seizures are one of the most common neurological complications encountered in the intensive care unit(ICU).They can occur in the background of exacerbation of a known neurological disease or secondary to non-neurological conditions such as sepsis and metabolic disturbances.However,there is a paucity of literature on the incidence and pattern of new-onset seizures in ICUs.AIM To study the incidence and patterns of new-onset seizures in patients admitted to the medical ICU.METHODS This was a prospective,multicenter,observational study performed in two tertiary care centers in Hyderabad,India over a period of 1 year.Patients upon ICU admission,who developed new-onset generalized tonic clonic seizures(GTCS),were enrolled.Those with a pre-existing seizure disorder,acute cerebrovascular accident,head injury,known structural brain lesions,or chronic liver disease were excluded as they have a higher likelihood of developing seizures.All enrolled patients were subjected to biochemical routines,radiological imaging of either computed tomography or magnetic resonance imaging,and other relevant laboratory tests as per clinical suspicion according to the protocol,and their data were recorded.Statistical analyses were conducted using descriptive statistics,χ2 tests,and linear regression.RESULTS A total of 61 of 2522 patients developed GTCS.Among all etiologies of seizures,metabolic causes were most frequent(35%)followed by infective causes(27%)and others(new-onset structural,drug withdrawal,druginduced,toxicology-related,and miscellaneous factors).Logistic regression analysis showed that increased sodium and calcium levels were associated with a lower likelihood of developing seizures.CONCLUSION This study identified the etiology of new-onset seizures developing in critically ill patients admitted to the ICU.These findings highlight the need for targeted monitoring of those at risk of developing seizures.

Development and validation of a nomogram for predicting in-hospital mortality of intensive care unit patients with liver cirrhosis

BACKGROUND Liver cirrhosis patients admitted to intensive care unit(ICU)have a high mortality rate.AIM To establish and validate a nomogram for predicting in-hospital mortality of ICU patients with liver cirrhosis.METHODS We extracted demographic,etiological,vital sign,laboratory test,comorbidity,complication,treatment,and severity score data of liver cirrhosis patients from the Medical Information Mart for Intensive Care IV(MIMIC-IV)and electronic ICU(eICU)collaborative research database(eICU-CRD).Predictor selection and model building were based on the MIMIC-IV dataset.The variables selected through least absolute shrinkage and selection operator analysis were further screened through multivariate regression analysis to obtain final predictors.The final predictors were included in the multivariate logistic regression model,which was used to construct a nomogram.Finally,we conducted external validation using the eICU-CRD.The area under the receiver operating characteristic curve(AUC),decision curve,and calibration curve were used to assess the efficacy of the models.RESULTS Risk factors,including the mean respiratory rate,mean systolic blood pressure,mean heart rate,white blood cells,international normalized ratio,total bilirubin,age,invasive ventilation,vasopressor use,maximum stage of acute kidney injury,and sequential organ failure assessment score,were included in the multivariate logistic regression.The model achieved AUCs of 0.864 and 0.808 in the MIMIC-IV and eICU-CRD databases,respectively.The calibration curve also confirmed the predictive ability of the model,while the decision curve confirmed its clinical value.CONCLUSION The nomogram has high accuracy in predicting in-hospital mortality.Improving the included predictors may help improve the prognosis of patients.

Effect of internet multiple linkage mode-based extended care combined with in-hospital comfort care on colorectal cancer patients undergoing colostomy

BACKGROUND Patients with colorectal cancer may need postoperative nursing to improve prognosis,and conventional nursing is not effective.Clinical research is needed to explore nursing methods that can more effectively improve postoperative conditions on colorectal cancer patients undergoing colostomy.AIM To explore the effect of internet multiple linkage mode-based extended care combined with in-hospital comfort care on colorectal cancer patients undergoing colostomy.METHODS Data from 187 patients with colostomy treated in our hospital from May 2019 to March 2022 were collected and divided into three groups,A(n=62),B(n=62)and C(n=63),according to different intervention methods.Group A received internet multiple linkage mode-based extended care combined with in-hospital comfort care.Group B received internet multiple linkage mode-based extended care.Group C received usual care intervention.Complications were compared among the three groups.The stoma self-efficacy scale,Hamilton Anxiety Scale,RESULTS The complication rate of group A,B and C(16.13%,20.97%and 60.32%,respectively)was significantly different(all P<0.05).The incidence of complications in groups A and B was lower than that in group C,and there was no significant difference between groups A and B(P>0.05).After intervention,the scores of ostomy care,social contact,diet choice,confidence in maintaining vitality,confidence in self-care of ostomy,confidence in sexual life,confidence in sexual satisfaction and confidence in physical labor in the three groups were all higher than before intervention,and the scores of groups A and B were higher than those of group C,with statistical significance(P<0.05).The Hamilton Anxiety Scale and Hamilton Depression Scale scores of the three groups after intervention were lower than those before intervention.The scores of groups A and B were lower than those of group C,and the score of group A was lower than that of group B,all with statistical significance(all P<0.05).There was a statist-ically significant difference in cancer-induced fatigue among the three groups(P<0.05).After intervention,the scores of physical health,psychological health,social health and mental health of the three groups were lower than before the intervention.The scores of group A and B were lower than that of group C;and the score of group A was lower than that of group B,all with statistical significance(all P<0.05).CONCLUSION Internet multiple linkage mode-based extended care combined with in-hospital comfort care can effectively improve self-efficacy,bad mood,cancer-related fatigue and life quality of colorectal cancer patients undergoing colostomy.

Predictive value of neutrophil-to-lymphocyte ratio in in-hospital mortality in sepsis patients:A cross-sectional study

Objective:To explore the predictive value of neutrophil-to-lymphocyte ratio(NLR)in in-hospital mortality in sepsis patients.Methods:A prospective observational cross-sectional study was conducted on 100 patients with septicemia.The data about the patient’s demography,medical history,general examination including pulse rate,blood pressure,etc,use of vasopressor support,need for renal replacement therapy,mechanical ventilation,outcome,and lab parameters including total lymphocyte count with neutrophil-to-lymphocyte ratio were recorded.And parameters between survivals and non-survivals were compared.Results:Out of 100 patients,80%were from rural backgrounds.Most patients were 50 to 59 years old.26 Patients were dead.The patients in the nonsurvivor group were older and more had a history of diabetes mellitus when compared with the survivor group.The non-survivor group had a higher NLR,APACHE栻,and SOFA score.Conclusions:NLR is a readily available parameter and can be used as a good prognostic indicator for mortality in sepsis patients.

Sedation reversal trends at outpatient ambulatory endoscopic center vs in-hospital ambulatory procedure center using a triage protocol

BACKGROUND Routine outpatient endoscopy is performed across a variety of outpatient settings.A known risk of performing endoscopy under moderate sedation is the potential for over-sedation,requiring the use of reversal agents.More needs to be reported on rates of reversal across different outpatient settings.Our academic tertiary care center utilizes a triage tool that directs higher-risk patients to the in-hospital ambulatory procedure center(APC)for their procedure.Here,we report data on outpatient sedation reversal rates for endoscopy performed at an inhospital APC vs at a free-standing ambulatory endoscopy digestive health center(AEC-DHC)following risk stratification with a triage tool.AIM To observe the effect of risk stratification using a triage tool on patient outcomes,primarily sedation reversal events.METHODS We observed all outpatient endoscopy procedures performed at AEC-DHC and APC from April 2013 to September 2019.Procedures were stratified to their respective sites using a triage tool.We evaluated each procedure for which sedation reversal with flumazenil and naloxone was recorded.Demographics and characteristics recorded include patient age,gender,body mass index(BMI),American Society of Anesthesiologists(ASA)classification,procedure type,and reason for sedation reversal.RESULTS There were 97366 endoscopic procedures performed at AEC-DHC and 22494 at the APC during the study period.Of these,17 patients at AEC-DHC and 9 at the APC underwent sedation reversals(0.017%vs 0.04%;P=0.06).Demographics recorded for those requiring reversal at AEC-DHC vs APC included mean age(53.5±21 vs 60.4±17.42 years;P=0.23),ASA class(1.66±0.48 vs 2.22±0.83;P=0.20),BMI(27.7±6.7 kg/m^(2) vs 23.7±4.03 kg/m^(2);P=0.06),and female gender(64.7%vs 22%;P=0.04).The mean doses of sedative agents and reversal drugs used at AEC-DHC vs APC were midazolam(5.9±1.7 mg vs 8.9±3.5 mg;P=0.01),fentanyl(147.1±49.9μg vs 188.9±74.1μg;P=0.10),flumazenil(0.3±0.18μg vs 0.17±0.17μg;P=0.13)and naloxone(0.32±0.10 mg vs 0.28±0.12 mg;P=0.35).Procedures at AEC-DHC requiring sedation reversal included colonoscopies(n=6),esophagogastroduodenoscopy(EGD)(n=9)and EGD/colonoscopies(n=2),whereas APC procedures included EGDs(n=2),EGD with gastrostomy tube placement(n=1),endoscopic retrograde cholangiopancreatography(n=2)and endoscopic ultrasound's(n=4).The indications for sedation reversal at AEC-DHC included hypoxia(n=13;76%),excessive somnolence(n=3;18%),and hypotension(n=1;6%),whereas,at APC,these included hypoxia(n=7;78%)and hypotension(n=2;22%).No sedation-related deaths or long-term post-sedation reversal adverse outcomes occurred at either site.CONCLUSION Our study highlights the effectiveness of a triage tool used at our tertiary care hospital for risk stratification in minimizing sedation reversal events during outpatient endoscopy procedures.Using a triage tool for risk stratification,low rates of sedation reversal can be achieved in the ambulatory settings for EGD and colonoscopy.

In-Hospital Outcomes in Minimally Invasive Mitral Valve Surgery: First Results in a Brazilian Single Center

Introduction: Treatments for cardiovascular diseases have increasingly evolved with the tendency to offer minimally invasive or transcatheter procedures instead of conventional sternotomy surgery. In this context, we highlight minimally invasive mitral valve surgery (MIMVS), which has been shown to be an increasingly solid option with some superior results when compared to the conventional technique: better pain control, shorter hospital stays, shorter recovery time, shorter readmission rate in the first postoperative year, better aesthetic results, and lower overall cost. Aim: This study aims to evaluate the stages of MIMVS, by primary mitral valve consultation, in our service and compare these results with data from the literature. Methods: All electronic medical records of patients who underwent MIMVS for primary mitral valve injury in the Encore Hospital from January 2020 to February 2023 were analyzed. Tabulation and statistical analysis were performed using the Microsoft Excel® program. Quantitative variables were presented as means, standard deviations. Results: 46 patients were enrolled in our study (Age: 59.1 ± 12.4 years old;60.8% Female, BMI: 26 ± 4.4 Kg/m2, Low risk STS score: 82.6%). The observed 30-day mortality was 2.1%, plastic rate of 23.9%, blood transfusion rate of 41.3%, length of stay in an intensive care bed (ICB) of 3.3 ± 3.3 days and hospital stay of 6.4 ± 5.1 days. Conclusions: We noticed that the MIMVS results carried out in our service agree with data from national and international literature with approximately 1.3 days more hospitalization in ICB.

Beyond statistical significance:Embracing minimal clinically important difference for better patient care

The minimal clinically important difference(MCID)represents a pivotal metric in bridging the gap between statistical significance and clinical relevance,addressing the direct impact of medical interventions from the patient's perspective.This comprehensive review analyzes the evolution,applications,and challenges of MCID across medical specialties,emphasizing its necessity in ensuring that clinical outcomes not only demonstrate statistical significance but also offer genuine clinical utility that aligns with patient expectations and needs.We discuss the evolution of MCID since its inception in the 1980s,its current applications across various medical specialties,and the methodologies used in its calculation,highlighting both anchor-based and distribution-based approaches.Furthermore,the paper delves into the challenges associated with the application of MCID,such as methodological variability and the interpretation difficulties that arise in clinical settings.Recommendations for the future include standardizing MCID calculation methods,enhancing patient involvement in setting MCID thresholds,and extending research to incorporate diverse global perspectives.These steps are critical to refining the role of MCID in patient-centered healthcare,addressing existing gaps in methodology and interpretation,and ensuring that medical interventions lead to significant,patient-perceived improvements.

Predictors and in-hospital prognosis of recurrent acute myocardial infarction

Objective To investigate the contributing factors and in-hospital prognosis of patients with or without recurrent acute myocardial infarction （AMI）. Methods A total of 1686 consecutive AMI patients admitted to Peking University People＇s Hospital from January 2010 to December 2015 were recruited. Their clinical characteristics were retrospectively compared between patients with or without a recurrent AMI. Then multivariable logistic regression was used to estimate the predictors of recurrent myocardial infarction. Results Recurrent AMI patients were older （69.3 ± 11.5 vs. 64.7 ± 12.8 years, P 〈 0.001） and had a higher prevalence of diabetes mellitus （DM） （52.2% vs. 35.0%, P 〈 0.001） compared with incident AMI patients, they also had worse heart function at admission, more severe coronary disease and lower reperfusion therapy. Age （OR = 1.03, 95% CI： 1.02-1.05; P 〈 0.001）, DM （OR = 1.86, 95% CI： 1.37-2.52; P 〈 0.001） and reperfusion therapy （OR = 0.74; 95% CI： 0.52-0.89; P 〈 0.001） were independent risk factors for recurrent AMI Recurrent AMI patients had a higher in-hospital death rate （12.1% vs. 7.8%, P = 0.039） than incident AMI patients. Conclusions Recurrent AMI patients presented with more severe coronary artery conditions. Age, DM and reperfusion therapy were independent risk factors for recurrent AMI, and recurrent AM1 was related with a high risk of in-hospital death.

Prognostic Value of Neutrophil to Lymphocyte Ratio for In-hospital Mortality in Elderly Patients with Acute Myocardial Infarction

Coronary artery disease （CAD） is a multifactorial disease in which inflammation plays a central role. This study aimed to investigate the association of inflammatory markers such as the neutrophil to lymphocyte ratio （NLR）, the Global Registry of Acute Coronary Events （GRACE） score with in-hospital mortality of elderly patients with acute myocardial infarction （AMI） in an attempt to explore the prognostic value of these indices for elderly AMI patients. One thousand consecutive CAD patients were divided into two groups based on age 60. The laboratory and clinical characteristics were assessed retrospectively by reviewing the medical records. The NLR and GRACE score were calculated. In the elderly （〉60 years）, patients with non-ST-elevation myocardial infarction （NSTEMI） and ST-elevation myocardial infarction （STEMI） had significantly higher NLR than did those with unstable angina （UA） and stable angina pectoris （SAP） （P〈0.01）. The NLR was considerably elevated in older AMI patients compared with their younger counterparts （〈60 years） （P〈0.05）. In elderly AMI patients, the NLR was considerably higher in the high-risk group than in both the low-risk and mediumrisk groups based on the GRACE score （P〈0.05 and P〈0.01, respectively）, and the NLR was positively correlated with the GRACE score （r=0.322, P〈0.001）. Either the NLR level or the GRACE score was significantly higher in the death group than in the surviving group （P〈0.05）. By curve receiver operator characteristic curve （ROC） analysis, the optimal cut-off levels of 9.41 for NLR and 174 for GRACE score predicted in-hospital death [ROC area under the curve （AUC） 0.771 and 0.787, respectively, P〈0.001]. It was concluded that an elevated NLR is a potential predictor of in-hospital mortality in elderly patients with AMI.

Patterns of in-hospital mortality and bleeding complications following PCI for very elderly patients： insights from the Dartmouth Dynamic Registry

Background Very elderly patients （age 〉 85 years） are a rapidly increasing segment of the population. As a group, they experience high rates of in-hospital mortality and bleeding complications following percutaneous coronary intervention （PCI）. However, the relationship between bleeding and mortality in the very elderly is unknown. Methods Retrospective review was performed on 17,378 consecutive PCI procedures from 2000 to 2015 at Dartmouth-Hitchcock Medical Center. Incidence of bleeding during the index PCI admission （bleeding requiring transfusion, access site hematoma 〉 5 cm, pseudoaneurysm, and retroperitoneal bleed） and in-hospital mortality were reported for four age groups （〈 65 years, 65-74 years, 75-84 years, and ≥ 85 years）. The mortality of patients who suffered bleeding complications and those who did not was calculated and multivariate analysis was performed for in-hospital mortality. Lastly, known predictors of bleeding were compared between patients age 〈 85 years and age ≥85 years. Results Of 17,378 patients studied, 1019 （5.9%） experienced bleeding and 369 （2.1%） died in-hospital following PCI. Incidence of bleeding and in-hospital mortality increased monotonically with increasing age （mortality： 0.94%, 2.27%, 4.24% and 4.58%; bleeding： 3.96%, 6.62%, 10.68% and 13.99% for ages 〈 65, 65-4, 75-84 and ≥ 85 years, respectively）. On multivariate analysis, bleeding was associated with increased mortality for all age groups except patients age ≥85 years [odds ratio （95% CI）： age 〈 65 years, 3.65 （1.99-6.74）; age 65-74 years, 2.83 （1.62-4.94）; age 75-84 years, 3.86 （2.56-5.82）, age ≥ 85 years 1.39 （0.49-3.95）]. Conclusions Bleeding and mortality following PCI increase with increasing age. For the very elderly, despite high rates of bleeding, bleeding is no longer predictive of in-hospital mortality following PCI.

Comparison of different versions of the quick sequential organ failure assessment for predicting in-hospital mortality of sepsis patients:A retrospective observational study

BACKGROUND:The quick sequential organ failure assessment(qSOFA)is recommended to identify sepsis and predict sepsis mortality.However,some studies have recently shown its poor performance in sepsis mortality prediction.To enhance its effectiveness,researchers have developed various revised versions of the qSOFA by adding other parameters,such as the lactate-enhanced qSOFA(LqSOFA),the procalcitonin-enhanced qSOFA(PqSOFA),and the modified qSOFA(MqSOFA).This study aimed to compare the performance of these versions of the qSOFA in predicting sepsis mortality in the emergency department(ED).METHODS:This retrospective study analyzed data obtained from an electronic register system of adult patients with sepsis between January 1 and December 31,2019.Receiver operating characteristic(ROC)curve analyses were performed to determine the area under the curve(AUC),with sensitivity,specificity,and positive and negative predictive values calculated for the various scores.RESULTS:Among the 936 enrolled cases,there were 835 survivors and 101 deaths.The AUCs of the LqSOFA,MqSOFA,PqSOFA,and qSOFA were 0.740,0.731,0.712,and 0.705,respectively.The sensitivity of the LqSOFA,MqSOFA,PqSOFA,and qSOFA were 64.36%,51.40%,71.29%,and 39.60%,respectively.The specificity of the four scores were 70.78%,80.96%,61.68%,and 91.62%,respectively.The LqSOFA and MqSOFA were superior to the qSOFA in predicting in-hospital mortality.CONCLUSIONS:Among patients with sepsis in the ED,the performance of the PqSOFA was similar to that of the qSOFA and the values of the LqSOFA and MqSOFA in predicting in-hospital mortality were greater compared to qSOFA.As the added parameter of the MqSOFA was more convenient compared to the LqSOFA,the MqSOFA could be used as a candidate for the revised qSOFA to increase the performance of the early prediction of sepsis mortality.

Development and validation of an emergency bloodstream infection score for predicting in-hospital mortality in patients with community-acquired bloodstream infections

BACKGROUND:Community-acquired bloodstream infections(CABSIs)are common in the emergency departments,and some progress to sepsis and even lead to death.However,limited information is available regarding the prediction of patients with high risk of death.METHODS:The Emergency Bloodstream Infection Score(EBS)for CABSIs was developed to visualize the output of a logistic regression model and was validated by the area under the curve(AUC).The Mortality in Emergency Department Sepsis(MEDS),Pitt Bacteremia Score(PBS),Sequential Organ Failure Assessment(SOFA),quick Sequential Organ Failure Assessment(qSOFA),Charlson Comorbidity Index(CCI),and McCabe–Jackson Comorbid Classification(MJCC)for patients with CABSIs were computed to compare them with EBS in terms of the AUC and decision curve analysis(DCA).The net reclassification improvement(NRI)index and integrated discrimination improvement(IDI)index were compared between the SOFA and EBS.RESULTS:A total of 547 patients with CABSIs were included.The AUC(0.853)of the EBS was larger than those of the MEDS,PBS,SOFA,and qSOFA(all P<0.001).The NRI index of EBS in predicting the in-hospital mortality of CABSIs patients was 0.368(P=0.04),and the IDI index was 0.079(P=0.03).DCA showed that when the threshold probability was<0.1,the net benefit of the EBS model was higher than those of the other models.CONCLUSION:The EBS prognostic models were better than the SOFA,qSOFA,MEDS,and PBS models in predicting the in-hospital mortality of patients with CABSIs.

Comprehensive Level One Trauma Center Could Lower In-hospital Mortality of Severe Trauma in China

Trauma is a major health and social problem in the US and China, It constitutes the main cause of death in people aged 45 or under in both countries112]. There is clear evidence from clinical studies that a large percentage of these deaths are needless and preventable if better treatment and prevention programs are available12-3].

Neutron Capture Therapy (NCT) & In-Hospital Neutron Irradiator (IHNI)——a new technology on binary targeting radiation therapy of cancer

BNCT is finally becoming ＂a new option against cancer＂. The difficulties for its development progress of that firstly is to improve the performance of boron compounds, secondly, it is the requirements of quantification and accuracy upon radiation dosimetry evaluation in clinical trials. Furthermore, that is long anticipation on hospital base neutron sources. It includes dedicated new NCT reactor, accelerator based neutron sources, and isotope source facilities. In ad- dition to reactors, so far, the technology of other types of sources for clinical trials is not yet completely proven. The In- Hospital Neutron lrradiator specially designed for NCT, based on the MNSR successfully developed by China, can be installed inside or near the hospital and operated directly by doctors. The Irradiator has two neutron beams for respective treatment of the shallow and deep tumors. It is expected to initiate operation in the end of this year. It would provide a safe, low cost, and effective treatment tool for the NCT routine application in near future.

High-density Lipoprotein Cholesterol and In-hospital Mortality in Patients with Acute Aortic Dissection

The association between high-density lipoprotein cholesterol（HDL-C） and mortality in patients with acute aortic dissection（AAD） is unclear. From January 2007 to January 2014, a total of 928 consecutive AAD patients who were admitted within 48 h after the onset of symptoms were enrolled in the study. Patients were divided into two groups according to whether serum HDL-C level was below the normal lower limit or not. The Cox proportional hazard regression model was used to identify the predictive value of HDL-C for in-hospital mortality in patients with AAD. As compared with normal HDL-C group（n=585）, low HDL-C group（n=343） had lower levels of systolic blood pressure and hemoglobin and higher levels of leukocyte, alanine aminotransferase, blood glucose, blood urea nitrogen, creatinine and urea acid. Low HDL-C group had significantly higher in-hospital mortality than normal HDL-C group（21.6% vs. 12.6%, log-rank=10.869, P=0.001）. After adjustment for baseline variables including demographics and biologic data, the increased risk of in-hospital mortality in low HDL-C group was substantially attenuated and showed no significant difference（adjusted hazard ratio, 1.23; 95% confidence interval, 0.86–1.77; P=0.259）. Low HDL-C is strongly but not independently associated with in-hospital mortality in patients with AAD.

Impact of gout on in-hospital outcomes of acute coronary syndrome-related hospitalizations and revascularizations: Insights from the national inpatient sample

BACKGROUND Previous studies have established a role of gout in predicting risk and prognosis of cardiovascular diseases. However, large-scale data on the impact of gout on inpatient outcomes of acute coronary syndrome (ACS)-related hospitalizations and post-revascularization is inadequate. AIM To evaluate the impact of gout on in-hospital outcomes of ACS hospitalizations, subsequent healthcare burden and predictors of post-revascularization inpatient mortality. METHODS We used the national inpatient sample (2010-2014) to identify the ACS and goutrelated hospitalizations, relevant comorbidities, revascularization and postrevascularization outcomes using the ICD-9 CM codes. A multivariable analysis was performed to evaluate the predictors of post-revascularization in-hospital mortality. RESULTS We identified 3144744 ACS-related hospitalizations, of which 105198 (3.35%) also had gout. The ACS-gout cohort were more often older white males with a higher prevalence of comorbidities. Coronary artery bypass grafting was required more often in the ACS-gout cohort. Post-revascularization complications including cardiac (3.2% vs 2.9%), respiratory (3.5% vs 2.9%), and hemorrhage (3.1% vs 2.7%) were higher whereas all-cause mortality was lower (2.2% vs 3.0%) in the ACSgout cohort (P < 0.001). An older age (OR 15.63, CI: 5.51-44.39), non-elective admissions (OR 2.00, CI: 1.44-2.79), lower household income (OR 1.44, CI: 1.17- 1.78), and comorbid conditions predicted higher mortality in ACS-gout cohort undergoing revascularization (P < 0.001). Odds of post-revascularization inhospital mortality were lower in Hispanics (OR 0.45, CI: 0.31-0.67) and Asians (OR 0.65, CI: 0.45-0.94) as compared to white (P < 0.001). However, postoperative complications significantly raised mortality odds. Mean length of stay, transfer to other facilities, and hospital charges were higher in the ACS-gout cohort. CONCLUSION Although gout was not independently associated with an increased risk of postrevascularization in-hospital mortality in ACS, it did increase postrevascularization complications.

The Relationship Between Mean Platelet Volume and In-Hospital Mortality in Geriatric Patients with ST Segment Elevation Myocardial Infarction Who Underwent Primary Percutaneous Coronary Intervention

Objective:We planned to investigate the effect of mean platelet volume(MPV)on in-hospital mortality and coronary risk factors in geriatric patients with ST segment elevation myocardial infarction(STEMI)who underwent primary percutaneous coronary intervention(PCI).Methods:We enrolled 194 consecutive STEMI patients.The study population was divided into two groups on the basis of admission MPVs.The high-MPV group(n=49)included patients in the highest tertile(>8.9 fL),and the low-MPV group(n=145)included patients with a value in the lower two tertiles(≤8.9 fL).Clinical characteristics,in-hospital mortality,cardiovascular risk factors,and outcomes of primary PCI were analyzed.Results:The patients in the high-MPV group were older,more of them had three-vessel disease,and they had higher in-hospital mortality.Patients with in-hospital death were older,had higher Gensini score,creatinine concentration,and MPV,and had lower HDL cholesterol concentration.MPV,age,HDL cholesterol concentration,creatinine concentration,and Gensini score were found to be independent predictors of in-hospital death.Conclusion:These results suggest that high admission MPV levels are associated with increased in-hospital mortality in geriatric patients with STEMI undergoing primary PCI.

Significant risk factors for intensive care unit-acquired weakness:A processing strategy based on repeated machine learning

BACKGROUND Intensive care unit-acquired weakness(ICU-AW)is a common complication that significantly impacts the patient's recovery process,even leading to adverse outcomes.Currently,there is a lack of effective preventive measures.AIM To identify significant risk factors for ICU-AW through iterative machine learning techniques and offer recommendations for its prevention and treatment.METHODS Patients were categorized into ICU-AW and non-ICU-AW groups on the 14th day post-ICU admission.Relevant data from the initial 14 d of ICU stay,such as age,comorbidities,sedative dosage,vasopressor dosage,duration of mechanical ventilation,length of ICU stay,and rehabilitation therapy,were gathered.The relationships between these variables and ICU-AW were examined.Utilizing iterative machine learning techniques,a multilayer perceptron neural network model was developed,and its predictive performance for ICU-AW was assessed using the receiver operating characteristic curve.RESULTS Within the ICU-AW group,age,duration of mechanical ventilation,lorazepam dosage,adrenaline dosage,and length of ICU stay were significantly higher than in the non-ICU-AW group.Additionally,sepsis,multiple organ dysfunction syndrome,hypoalbuminemia,acute heart failure,respiratory failure,acute kidney injury,anemia,stress-related gastrointestinal bleeding,shock,hypertension,coronary artery disease,malignant tumors,and rehabilitation therapy ratios were significantly higher in the ICU-AW group,demonstrating statistical significance.The most influential factors contributing to ICU-AW were identified as the length of ICU stay(100.0%)and the duration of mechanical ventilation(54.9%).The neural network model predicted ICU-AW with an area under the curve of 0.941,sensitivity of 92.2%,and specificity of 82.7%.CONCLUSION The main factors influencing ICU-AW are the length of ICU stay and the duration of mechanical ventilation.A primary preventive strategy,when feasible,involves minimizing both ICU stay and mechanical ventilation duration.

Risk factors for adverse in-hospital outcomes in acute colonic diverticular hemorrhage

AIM: To investigate the factors associated with transfusion, further bleeding, and prolonged length of stay.METHODS: In total, 153 patients emergently hospitalized for diverticular bleeding who were examined by colonoscopy were prospectively enrolled. Patients in whom the bleeding source was identified received endoscopic treatment such as clipping or endoscopic ligation. After spontaneous cessation of bleeding withconservative treatment or hemostasis with endoscopic treatment, all patients were started on a liquid food diet and gradually progressed to a solid diet over 3d, and were discharged. At enrollment, we assessed smoking, alcohol, medications [non-steroidal antiinflammatory drugs(NSAIDs)], low-dose aspirin, and other antiplatelets, warfarin, acetaminophen, and oral corticosteroids), and co-morbidities [hypertension,diabetes mellitus, dyslipidemia, cerebro-cardiovascular disease, chronic liver disease, and chronic kidney disease(CKD)]. The in-hospital outcomes were need for transfusion, further bleeding after spontaneous cessation of hemorrhage, and length of hospital stay.The odds ratio(OR) for transfusion need, further bleeding, and prolonged length of stay were estimated by logistic regression analysis.RESULTS: No patients required angiographic embolization or surgery. Stigmata of bleeding occurred in 18% of patients(27/153) and was treated by endoscopic procedures. During hospitalization, 40patients(26%) received a median of 6 units of packed red blood cells. Multivariate analysis revealed that female sex(OR = 2.5, P = 0.02), warfarin use(OR= 9.3, P < 0.01), and CKD(OR = 5.9, P < 0.01)were independent risk factors for transfusion need.During hospitalization, 6 patients(3.9%) experienced further bleeding, and NSAID use(OR = 5.9, P = 0.04)and stigmata of bleeding(OR = 11, P < 0.01) were significant risk factors. Median length of hospital stay was 8 d. Multivariate analysis revealed that age > 70years(OR = 2.1, P = 0.04) and NSAID use(OR = 2.7,P = 0.03) were independent risk factors for prolonged hospitalization(≥ 8 d).CONCLUSION: In colonic diverticular bleeding, female sex, warfarin, and CKD increased the risk of transfusion requirement, while advanced age and NSAID increased the risk of prolonged hospitalization.
