Independent Prognostic Factor For Mortality Research Articles

Mortality and cardiovascular risk in vasculitis ANCA. Importance of hypertension and renal function. Experience from southern Spain

BackgroundCardiovascular disease (CVD) is one of the principal causes of death in antineutrophil cytoplasmic antibody-(ANCA)-associated vasculitis (AAV). ObjectivesTo evaluate the mortality and it's causes and CVD and its vascular risk factors (VRFs) in AAV patients in Andalusia. MethodsA multicenter cohort of 220 AAV patients followed-up from 1979 until June 2020 was studied in Andalussia, south of Spain. The information, including socio-demographic and clinical data was recorded retrospectively through chart review. Data was analysed using Chi2, ANOVA and Cox proportional hazards regresion as uni and multivariate test with a 95% confidence interval (CI). ResultsDuring a mean ± standard deviation follow-up of 96.79 ± 75.83 months, 51 patients died and 30 presented at least one CVE. Independent prognostic factors of mortality were age (HR 1.083, p=0.001) and baseline creatinine (HR 4.41, p=0.01). Independent prognostic factors of CVE were age [hazard ratio (HR) 1.042, p=0.005] and the presence of hypertension (HTN) six months after diagnosis (HR 4.641, p=0.01). HTN, diabetes and renal failure, all of these important VRFs, are more prevalent in AAV patients than it is described in matched general population. ConclusionsAge and baseline renal function, but not CVEs, are predictors of mortality and age and early HTN are independent predictors for having a CVE. CVD screening in AAV patients is demanded.

Prognostic value of primary tumor and lymph node volumetric metabolic parameters at pre-treatment F-18 FDG PET/CT in nasopharyngeal carcinoma

BackgroundThe aim of this study was to evaluate the prognostic significance of volumetric metabolic parameters of pre-treatment PET/CT along with clinical characteristics in patients with non-metastatic nasopharyngeal carcinoma. Material and methodsSeventy-nine patients with nasopharyngeal carcinoma underwent F18- FDG PET/CT for pretreatment evaluation and included in this study. The patient features (patient age, tumor histopathology, T and N stage, size of primary tumor and the largest cervical lymph node) and PET parameters were analyzed: maximum, mean and peak standardized uptake values (SUVmax, SUVmean, SUVpeak), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) for primary tumor and largest cervical lymph node. After treatment, patients were evaluated for disease progression and mortality. Survival analysis for progression-free survival (PFS) and over-all survival (OS) was performed with Kaplan–Meier method using PET findings and clinical characteristics. ResultsThe median follow-up duration was 29.7 months (range 3–125 months). Among clinical characteristics, no parameters had significance association for PFS. Primary tumor-MTV and cervical lymph node-MTV were independent prognostic factors for PFS (p = 0.025 and p = 0.004, respectively).Patients with primary tumor-MTV >19.4 and patients with lymph node-MTV>3.4 had shorter PFS. For OS, age and the size of the lymph node were independent prognostic factor (p = 0.031 and p = 0.029).Patients with age over 54 years and patients with lymph node size >1 cm were associated with decreased OS. ConclusionPrimary tumor-MTV and lymph node-MTV on pre-treatment PET/CT are significant prognostic factors for long-term PFS in non-metastatic nasopharyngeal carcinoma.We consider that measuring MTV as volume-based metabolic parameter on pretreatment PET/CT may contribute decision of treatment intensity and individualized risk stratification and may improve long-term PFS. Additionally, age and the size of lymph node are independent prognostic factors for mortality.

Prognostic significance of uncertain resection for metastasis in the highest mediastinal lymph node after surgery for clinical N0 non-small cell lung cancer.

The International Association for the Study of Lung Cancer defined types of surgical resection and considered the positivity of the highest mediastinal lymph node resected a parameter of "uncertain resection" (R-u). We investigated the metastases in the highest mediastinal lymph node, defined as the lowest numerically numbered station among those resected. We aimed to evaluate the prognostic value of R-u compared with R0. We selected 550 patients with non-small cell lung cancer at clinical Stage I, IIA, IIB (T3N0M0), or IIIA (T4N0M0) undergoing lobectomy and systematic lymphadenectomy between 2015 and 2020. The R-u group included patients with positive highest mediastinal resected lymph node. In the groups of patients with mediastinal lymph node metastasis, we defined 31 as R-u (45.6%, 31/68). The incidence of metastases in the highest lymph node was related to the pN2 subgroups (p < 0.001) and the type of lymphadenectomy performed (p < 0.001). The survival analysis compared R0 and R-u: 3-year disease-free survival was 69.0% and 20.0%, respectively, and 3-year overall survival was 78.0% and 40.0%, respectively. The recurrence rate was 29.7% in R0 and 71.0% in R-u (p-value < 0.001), and the mortality rate was 18.9% and 51.6%, respectively (p-value < 0.001). R-u variable showed a tendency to be a significant prognostic factor for disease-free survival and overall survival (hazard ratio: 4.6 and 4.5, respectively, p-value < 0.001). The presence of metastasis in the highest mediastinal lymph node removed seems to be an independent prognostic factor for mortality and recurrence. The finding of these metastases represents the margin of cancer dissemination at the time of surgery, so it could imply metastasis into the N3 node or distant metastasis.

CLINICAL AND LABORATORY FEATURES RELATED TO MORTALITY RATE OF BLOOD STREAM INFECTION PATIENTS ADMITTED TO NATIONAL HOSPITAL FOR TROPICAL DISEASES (7/2017 - 6/2020)

Objectives: The aim of this study was to evaluate clinical and laboratory features related to mortality rate of blood stream infection patients admitted to National hospital for Tropical Diseases.&#x0D; Subjects and methods: A cross - sectional study was conducted among patients diagnosed blood stream infection from 7/2017 to 6/2010 in National hospital for Tropical Diseases. A total of 200 patients with clinical sign, symptoms of sepsis and positive blood culture were included in the study. Univariate and multivariate logistic regressions were used to identify independent prognostic factors for mortality. &#x0D; Results: Of 200 blood stream infection patients, 131 patients were male (65.5%); 150 patients (75%) had comorbidities, the most common diseases are cardiovascular diseases (26%), diabetes mellitus (23.5%), hepatic diseases (18.5%) and alcoholism (13%). E. coli (32%), S.aureus (28.5%) are the most frequent causes indentified in blood culture. There were 44 died (22%) and 156 survived (78%). Platelet &lt; 100G/L (OR = 3.61), rAPTT &gt; 1.25 (OR = 6.26), shock (OR = 71.99), the number of organ dysfunctions ≥ 3 (OR = 4.06) were independent prognostic factors. &#x0D; Conclusion: Septic shock, multiple organ failure and thrombocytopenia are the prognostic factors for mortality of blood stream infection. It should be early detected in blood stream infection for intervention.

Sarcopenic obesity by the ESPEN/EASO criteria for predicting mortality in advanced non-small cell lung cancer

The European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Association for the Study of Obesity (EASO) recently released the first international consensus on the diagnostic criteria for sarcopenic obesity (SO), which recommended skeletal muscle mass adjusted for body weight (SMM/W) to determine low muscle mass. SMM adjusted for body mass index (SMM/BMI) appeared to be better associated with physical performance than SMM/W. Thus, we modified the ESPEN/EASO criteria by using SMM/BMI. We aimed (1) to evaluate the agreement of the ESPEN/EASO-defined SO (SOESPEN) and the modified ESPEN/EASO-defined SO (SOESPEN-M) with other commonly used SO definitions, and (2) to compare different SO definitions for predicting mortality in a prospective cohort with advanced non-small cell lung cancer (NSCLC). This prospective study included patients with advanced NSCLC. We defined SO according to five different diagnostic criteria: SOESPEN, SOESPEN-M, Asian Working Group for Sarcopenia (AWGS)-determined sarcopenia with BMI-determined obesity (SOAWGS), computed tomography-derived sarcopenia with BMI-determined obesity (SOCT), and fat mass to fat-free mass ratio >0.8 (SOFM). The outcome was all-cause mortality. Of the 639 participants (mean age 58.6 years, 229 women) we studied, 488 (76.4%) died during the median follow-up period of 25 months. SMM/BMI was significantly lower in the death group than in the survivor group (men: p=0.001, women: p<0.001), but SMM/W was not. Only 3 (0.47%) participants metall five SO diagnostic criteria. SOESPEN showed an excellent agreement with SOESPEN-M (Cohen's kappa=0.896), a moderate agreement with SOAWGS (Cohen's kappa=0.415), but poor agreements with SOCT and SOFM (Cohen's kappa=0.078 and 0.092, respectively). After full adjustment for potential confounders, SOESPEN (HR 1.54, 95% CI 1.26-1.89), SOESPEN-M (HR 1.56, 95% CI 1.26-1.92), and SOAWGS (HR 1.43, 95% CI 1.14-1.78) were significantly associated with mortality. However, SOCT (HR 1.17, 95% CI 0.87-1.58) and SOFM (HR 1.15, 95% CI 0.90-1.46) showed no significant association with mortality. SOESPEN showed an excellent agreement with SOESPEN-M, a moderate agreement with SOAWGS, but poor agreements with SOCT and SOFM. SOESPEN, SOESPEN-M, and SOAWGS were independent prognostic factors for mortality in our study population, but SOCT and SOFM were not. Although SMM/BMI was better associated with survival than SMM/W, SOESPEN-M did not show an advantage in predicting survival over SOESPEN.

Impact of frailty on long-term mortality in older patients receiving intensive care via the emergency department

The aim of this study was to evaluate whether frailty was associated with 6-month mortality in older adults who were admitted to the intensive care unit (ICU) with an illness requiring emergency care. The investigation was a prospective, multi-center, observational study conducted among the ICUs of 17 participating hospitals. Patients ≥ 65 years of age who were admitted to the ICU directly from an emergency department visit were assessed to determine their baseline Clinical Frailty Scale (CFS) scores before the illness and were surveyed 6 months after admission. Among 650 patients included in the study, the median age was 79 years old, and overall mortality at 6 months was as low as 21%, ranging from 6.2% in patients with CFS 1 to 42.9% in patients with CFS ≥ 7. When adjusted for potential confounders, CFS score was an independent prognostic factor for mortality (one-point increase in CFS, adjusted risk ratio with 95% confidence interval 1.19 [1.09–1.30]). Quality of life 6 months after admission worsened as baseline CFS score increased. However, there was no association between total hospitalization cost and baseline CFS. CFS is an important predictor of long-term outcomes among critically ill older patients requiring emergent admission.

Marital Status Independently Predicts Mortality in Adult Patients with Craniopharyngioma: A SEER-Based Study

The relationship between marital status and overall survival (OS) in adult patients with craniopharyngioma has not been explored in depth. We aimed to elucidate the impact of marital status on the prognosis of craniopharyngioma patients excluding bias from baseline demographics and treatment. We extracted 1539 patients diagnosed with craniopharyngioma between 2000 and 2019 from the Surveillance, Epidemiology, and End Results database and divided patients into 4 marital subgroups: married, single, divorced/separated, and widowed. Kaplan-Meier curves with a log-rank test were used to discern differences in OS between marital subgroups. Univariate and multivariate Cox regression were used to identify independent prognostic factors of mortality. There were 1539 eligible patients: 863 (56.1%) were married, 466 (30.3%) were single, 135 (8.8%) were divorced/separated, and 75 (4.9%) were widowed. Widowed patients had the worst mean OS, 5-year OS and 10-year OS at 84.2months, 58.0% and 26.9%, respectively. After stratifying patients by age, our multivariate analysis showed that marital status was an independent predictor of mortality in middle-aged craniopharyngioma patients (40-60years, P < 0.001), but not in young adults (18-39years, P=0.646) or elderly patients (>60years, P= 0.076). Among middle-aged patients, single (hazard ratio 1.72, confidence interval 1.19-2.47, P= 0.004) and divorced/separated patients (hazard ratio=2.29, confidence interval=1.49-3.54, P < 0.001) showed a higher risk of mortality compared to married patients (reference). Marital status is an independent prognostic factor predicting OS for middle-aged patients with craniopharyngioma. Providing additional social and psychological support for single and divorced/separated patients may improve outcomes for this vulnerable population.

Delta Neutrophil Index as a New Early Mortality Predictor after Liver Transplantation.

Patients with liver disease display numerous defects of the immune system, so infection is a frequent complication of both acute and chronic liver disease. These infections are independently associated with poor outcomes after liver transplantation. Our objective was to evaluate the delta neutrophil index (DNI), a new inflammation marker, as a predictor of survival after liver transplantation (LT). This observational study retrospectively evaluated the records of 712 patients who underwent LT from January 2010 to February 2018. DNI was evaluated at pre-transplantation and 1, 7, 14, and 30 days after operation. Statistical analysis was performed using the T-test or chi-square test, and logistic regression analysis. The mean MELD score was 16.7 ± 9.4 (0-48). There were 125 mortality cases (17.8%) after liver transplantation. Mean DNI was 1.61 at pre-transplantation, 3.94 one day after operation, 2.67 seven days after operation, 1.61 fourteen days after operation, and 1.64 thirty days after operation, respectively. In multivariate analysis, DNI seven and fourteen days after operation was revealed as an independent prognostic factor for mortality after liver transplantation (p = 0.040 and p < 0.0001). The DNI is a simple and reliable predictor of patient mortality after liver transplantation.

Fibrosis score predicts mortality in patients with fibrotic hypersensitivity pneumonitis.

Variable clinical courses make it challenging to predict mortality resulting from fibrotic hypersensitivity pneumonitis (HP). This study evaluated the usefulness of radiologic parameters for predicting mortality in patients with fibrotic HP. Clinical data and high-resolution computed tomography (HRCT) images, which were scored for reticulation, honeycombing, ground glass opacity (GGO), consolidation, and mosaic attenuation (MA) by visual assessment, were retrospectively analyzed in a total of 101 patients with fibrotic HP (all biopsy-proven cases). Fibrosis score was defined as the sum of reticulation and honeycombing scores. The mean age of the 101 patients was 58.9 years, and 60.4% were females. During the follow-up (median: 55.5 months; interquartile range: 37.7-89.0 months), the 1-, 3-and 5-year mortality rates were 3.9, 16.8, and 32.7%, respectively. The non-survivors were older and had significantly lower lung function and minimum oxygen saturation during the 6-min walk test than the survivors. The non-survivors had higher scores of reticulation, honeycombing, GGO, fibrosis, and MA on HRCT than survivors. In the multivariable Cox analysis, reticulation, GGO, and fibrosis scores were independent prognostic factors for mortality in patients with fibrotic HP, as well as age. Fibrosis score showed great performance for predicting the 5-year mortality (AUC = 0.752, p < 0.001) and higher mortality was recorded for patients with high fibrosis score (≥12.0%) (the mean survival time: 58.3 vs. 146.7 months, p < 0.01) than those without. Our results suggest that radiologic fibrosis score may be a useful predictor of mortality in patients with fibrotic HP.

Epidemiological study on the impact of influenza vaccination on the clinical course of patients with COVID-19 and co-infection by both viruses in Gran Canaria, Spain

To analyze the frequency of influenza and SARS-CoV-2 co-infections, as well as the differences in the course of disease (risk of mortality, hospital and intensive care admissions) in patients infected with the SARS-CoV-2 virus in relation to flu vaccination status in the 2021-2022 season. Population-based observational retrospective study in a cohort of 19,850 patients diagnosed with COVID-19 between June 1, 2021 and February 28, 2022 on the island of Gran Canaria. A total of 1,789 patients (9%) diagnosed with COVID-19 had received flu vaccinations. 13,676 people (68.9%) had a full course of COVID-19 vaccinations. In the period between June 1, 2021 and February 28, 2022, 8 cases of flu and COVID-19 coinfection were recorded. Hypertension (18.5%), asthma (12.8%) and diabetes (7.2%) were the most frequent comorbidities. There were 147 deaths (0.7%). Older patients ([OR] 1.11 95% CI 1.09-1.13) and people with cancer ([OR] 4.21 95% CI 2.58-6.89) had a higher risk of dying from COVID-19 (p<0.05). Female sex was noted as a protective factor ([OR] 0.61 95% CI 0.40-0.92). Old age, male sex and cancer were independent prognostic factors for mortality. Three doses of SARS-CoV-2 vaccines and influenza vaccines were highly effective in preventing COVID-19-related deaths and hospital admissions. These findings suggest that flu vaccination can help control the pandemic.

ST-Segment Elevation Myocardial Infarction Differences between Genders - A Single Center Retrospective Analysis.

Although outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary interventions (PCI) have improved, women show higher mortality. To assess gender differences in presentation, management and in-hospital mortality, at 30-days, 6-months and 1-year after STEMI. We retrospectively collected data from 809 consecutive patients treated with primary PCI and compared the females versus males at the local intervention cardiology database. The level of significance used was p<0.05. Women were older than man (69,1±14,6 vs. 58,5±12,7 years; p<.001) with higher prevalence of age over 75 years (36.7% vs. 11.7%; p<.001), diabetes (30,6% vs. 18,5%; p=.001), hypertension (60.5% vs. 45.9%; p=.001), chronic kidney disease (3.4% vs. 0.6%; p=.010) and acute ischemic stroke (6.8% vs. 3.0%; p=.021). At presentation, women had more atypical symptoms, less chest pain (p=.014) and were more frequently in cardiogenic shock (p=.011)). Women had longer time until reperfusion (p=.001) and were less likely to receive optimal medical therapy (p<0.05). In-hospital mortality (p=.001), at 30-days (p<.001), 6-months (p<.001) and 1-year (16.4% vs. p<.001) was higher in women. The multivariate analysis identified age over 75 years (HR=4.25; 95% CI[1.67-10.77];p=.002), Killip class II (HR=8.80; 95% CI[2.72-28.41];p<.001), III (HR=5.88; 95% CI [0.99-34.80]; p=.051) and IV (HR=9.60; 95% CI[1.86-48.59];p=.007), Acute Kidney Injury (HR=2.47; 95% CI[1.00-6.13];p=.051) and days of hospitalization (HR=1.04; 95% CI[1.01-1.08];p=.030) but not female gender (HR=0.83; 95% CI[0.33-2.10];p=.690) as independent prognostic factors of mortality. Compared to men, women with STEMI undergoing primary PCI have higher mortality rates. Women admitted for STEMI have a worse risk profile, are treated with a higher reperfusion time related with system delays and are less likely to receive the recommended therapy. Female gender was not an independent prognostic factor for mortality in the studied population.

Serum troponin is elevated in acute decompensation and acute-on-chronic liver failure and is associated with severity of liver disease and short-term mortality

Background The role of high sensitive cardiac Troponin (hs-cTn) in patients with liver cirrhosis (LC) and liver-related acute events is not well established. Aim To assess the prognostic performance of hs-cTn I in acute decompensation (AD) and acute-on-chronic liver failure (ACLF). Methods Two cohorts of consecutive patients, a derivation (retrospective) and a validation (prospective), were evaluated and 30-day-mortality was recorded. Hs-cTnI values were measured. Very low hs-cTnΙ (4 ng/L) was considered the cutoff-level. Results A total of 296 patients with LC [69.3% male, median age 57 (IQR 51–68) years, MELD score 19 (13–25), ACLF (29.4%), AD (48.3%), and without liver-related acute events (22.3%)] were included in the derivation cohort. The 66.2% of total patients had hs-cTnI ≥4 ng/L. Patients with hs-cTnI ≥4 ng/L were older and had more severe LC compared to those with <4ng/L. The multivariate analysis demonstrated that age (p < 0.001) and MELD (p = 0.001) were independent variables associated with elevated hs-cTnI after adjustment for age, sex and hepatic encephalopathy in total patients. When ACLF and AD were analyzed separately, the mortality was higher in patients with hs-cTnI ≥ 4 ng/L compared to lower values (log-rank p = 0.036 and p = 0.019, respectively). In multivariate analysis, MELD (p < 0.001) and hs-cTnI ≥4 ng/L (p = 0.032) were independent prognostic factors of mortality in ACLF/AD groups, after adjustment for age and sex. Similar results were obtained from the validation cohort (N = 148). Conclusions hs-cTnI levels were higher in patients with severe liver disease. The low cutoff-point of 4 ng/L is accurate in ruling out non-survivors mainly in AD group.

Clinical Outcomes and Prognosis of Patients With Interstitial Lung Disease Undergoing Lung Cancer Surgery: A Propensity Score Matching Study

BackgroundPatients with interstitial lung disease (ILD) may have a poor prognosis after lung cancer surgery because of respiratory complications and increased recurrence rates due to limited resection. Few studies have investigated prognosis after surgery by matching clinical variables between patients with and without ILD. Patients and MethodsMedical records of patients who underwent lung cancer surgery between January 2010 and August 2020 at a referral hospital in South Korea were reviewed. Patients with ILD were identified based on preoperative computed tomography findings. Through propensity score matching, the clinical outcomes and prognoses of patients with (ILD group) and without ILD (control group) were compared. ResultsOf 1629 patients, 113 (6.9%) patients with ILD were identified, of whom 104 patients were matched. Before matching, patients with ILD had higher mean age, proportion of men, and rates of sublobar resection and squamous cell carcinoma than those without ILD. After matching, there was no significant difference in postoperative mortality rates between the control and ILD groups. The 5-year survival rate was significantly lower in the ILD group (66%) than in the control group (78.8%; P= .007). The 5-year survival rate of the ILD-GAP (Gender, Age, Physiology) stage III group (12.6%) was significantly lower than that of the ILD-GAP stage I (73.5%) and II groups (72.6%; P< .0001). Multivariable Cox analysis demonstrated that idiopathic pulmonary fibrosis, higher clinical stage, and recurrence were independent prognostic factors for mortality. ConclusionConcomitant ILD negatively affects long-term prognosis after lung cancer surgery, and ILD subtype and physiological severity assessment help predict prognosis after surgery.

Lower Platelet-to-Lymphocyte Ratio Was Associated with Poor Prognosis for Newborn Patients in NICU.

Background: Platelet-to-lymphocyte ratio (PLR) is reported to be related to the outcome of intensive care unit (ICU) patients. However, little is known about their associations with prognosis in newborn patients in neonatal ICU (NICU). The aim of the present study was to investigate the prognostic significance of the PLR for newborn patients in the NICU. Methods: Data on newborn patients in the NICU were extracted from the Multiparameter Intelligent Monitoring in Intensive Care III (MIMIC III) database. The initial PLR value of blood examinations within 24 h was analyzed. Spearman's correlation was used to analyze the association of PLR with the length of hospital and ICU stays. The chi-square test was used to analyze the association of PLR with mortality rate. Multivariable logistic regression was used to determine whether the PLR was an independent prognostic factor of mortality. The area under the receiver operating characteristic (ROC) curve was used to assess the predictive ability of models combining PLR with other variables. Results: In total, 5240 patients were enrolled. PLR was negatively associated with length of hospital stay and ICU stay (hospital stay: ρ = −0.416, p < 0.0001; ICU stay: ρ = −0.442, p < 0.0001). PLR was significantly correlated with hospital mortality (p < 0.0001). Lower PLR was associated with higher hospital mortality (OR = 0.85, 95% CI = 0.75–0.95, p = 0.005) and 90-day mortality (OR = 0.85, 95% CI = 0.76–0.96, p = 0.010). The prognostic predictive ability of models combining PLR with other variables for hospital mortality was good (AUC for Model 1 = 0.804, 95% CI = 0.73–0.88, p < 0.0001; AUC for Model 2 = 0.964, 95% CI = 0.95–0.98, p < 0.0001). Conclusion: PLR is a novel independent risk factor for newborn patients in the NICU.

PUMPING IRON: A QUALITY IMPROVEMENT STUDY FOR THE TREATMENT OF IRON DEFICIENCY ANEMIA IN AMBULATORY HEART FAILURE PATIENTS

PUMPING IRON: A QUALITY IMPROVEMENT STUDY FOR THE TREATMENT OF IRON DEFICIENCY ANEMIA IN AMBULATORY HEART FAILURE PATIENTS

The geriatric index of comorbidity as an outcome predictor of patients with acute mesenteric ischemia due to superior mesentery artery thromboembolism.

To describe the impact of comorbidities on in-hospital mortality and overall survival in patients with acute mesenteric ischemia (AMI) due to superior mesentery artery (SMA) thromboembolism. A retrospective study was conducted for 40 patients with AMI due to SMA thromboembolism who were treated in our hospital between February 2013 and December 2019. The presence of comorbidities was described and their severities were classified into 1-4 levels by Geriatric Index of Comorbidity (GIC), the comorbidities were defined as any distinct additional clinical entity that has existed. Univariate and cox proportional-hazards analyses were performed to determine the effect of comorbidities on in-hospital mortality and overall survival. During a mean follow-up of 15.05 ± 18.02months (range from 0.3 to 58months) for the 40 patients with AMI due to SMA thromboembolism, In-hospital mortality rate was 52.5% (21/40). One-year, 2-year, and 3-year overall estimated survival rates by the Kaplan-Meier method were 45%, 34%, and 26.5%, respectively, the average overall survival time was 20.84 ± 3.95 (95% CI: 13.10-28.58) months. In-hospital mortality was significantly related to the GIC classification (χ2 = 7.86, p = 0.049). The average overall survival was significantly related to the malignant tumor in pre-existing comorbidities and GIC classification (log-rank, p = 0.001). Cox proportional-hazards regressions analysis showed that the class 4 of comorbidities was an independent prognostic factor of mortality (p = 0.031, HR = 10.45 [95% CI: 1.24-87.70]). Comorbidity is common and an important factor associated with all-cause mortality in AMI patients due to SMA thromboembolism. In managing AMI patients, we recommend a timely diagnosis of both AMI condition and its associated comorbidities.

Lactate dehydrogenase/albumin ratio as a prognostic factor in severe acute respiratory distress syndrome cases associated with COVID-19.

Background:Patients with severe acute respiratory distress syndrome (ARDS) have high mortality rates; therefore, new biomarkers are necessary to predict the prognosis in the early stages. Serum lactate dehydrogenase (LDH) level is a specific marker of lung damage, but it is not sensitive because it is affected by several factors. This study aimed to determine whether the LDH/albumin ratio could be used as a prognostic biomarker in patients with severe ARDS due to COVID 19.Methods:Tertiary intensive care unit (ICU) patients with severe ARDS and confirmed COVID-19 diagnosis between August 1, 2020, and October 31, 2021, were included. The demographic and clinical characteristics of the patients were recorded from the hospital databases, together with laboratory results on the day of admission to the ICU and the length of stay in the ICU and hospital. LDH/albumin, lactate/albumin, C-reactive protein (CRP)/albumin, and BUN/albumin ratios were calculated. Logistic regression analysis was performed to determine independent risk factors affecting mortality.Results:Nine hundred and five patients hospitalized in a tertiary ICU were evaluated. Three hundred fifty-one patients with severe ARDS were included in this study. The mortality rate of the included patients was 61.8% (of 217/351). LDH/albumin, lactate/albumin, and BUN/albumin ratios were higher in the nonsurvivor group (P < .001). The area under the curve (AUC) from the receiver operating characteristic analysis that predicted in-hospital mortality was 0.627 (95% confidence intervals (CI): 0.574–0.678, P < .001) for the LDH/albumin ratio, 0.605 (95% CI: 0.551–0.656, P < .001) for lactate/albumin, and 0.638 (95% CI: 0.585–0.688, P < .001) for BUN/albumin. However, LDH/albumin ratio was independently associated with mortality in multivariate logistic regression analysis.Conclusion:LDH/albumin ratio can be used as an independent prognostic factor for mortality in patients with severe ARDS caused by COVID-19.

Chronic kidney disease is potentially an independent prognostic factor for death in Stevens-Johnson syndrome and toxic epidermal necrolysis patients.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are mucocutaneous conditions associated with high mortality and morbidity. Although several prognostic factors have been proposed, some may have yet to be identified. A 14-year retrospective cohort study of patients with SJS/TEN was conducted at a university-based hospital in Bangkok, Thailand, to explore additional prognostic factors for mortality of patients with SJS/TEN. Medical records of all patients aged ≥18 years who were diagnosed with SJS, SJS-TEN overlap, or TEN between 2007 and 2020 were reviewed. Univariate and multivariate analyses were performed to examine associations between death and potential prognostic factors. A total of 76 patients with a mean age of 52 years were enrolled. Among them, 46, 15, and 15 patients were diagnosed with SJS, SJS-TEN overlap, and TEN, respectively. Overall, 10 patients deceased, marking a mortality rate of 13.2%. Based on an algorithm for assessment of drug causality for epidermal necrolysis, drug was the major cause of disease (96.1%). Allopurinol and trimethoprim/sulfamethoxazole were the most frequent culprit drugs. Univariate analysis revealed nine prognostic factors related to death, i.e., age, malignancy, chronic kidney disease (CKD), coronary artery disease, heart rate >120 beats/min, diagnoses of SJS-TEN overlap and TEN, blood urea nitrogen (BUN) >10 mmol/L, hemoglobin <10 g/dL, and serum albumin <2 g/dL. Causality with regard to drug, drug notoriety, time interval from drug intake to onset of reaction, and timing of culprit drug withdrawal were not significantly associated with death. Four independent prognostic factors for mortality were identified from multivariate analysis, i.e., TEN (risk ratio [RR] 8.29, 95% confidence interval [CI]: 2.71–25.38), malignancy (RR 3.34, 95% CI: 1.68–6.69), BUN >10 mmol/L (RR 3.02, 95% CI: 1.28–7.14), and early-stage CKD (RR 4.81, 95% CI: 2.49–9.28). Our findings suggest that CKD is an independent prognostic factor for mortality of patients with SJS/TEN besides those from the SCORTEN.

Transcatheter arterial embolization for gastrointestinal bleeding: Clinical outcomes and prognostic factors predicting mortality.

We evaluated clinical outcome and prognostic factors predicting mortality of transcatheter arterial embolization (TAE) for acute gastrointestinal (GI) bleeding. Fifty-nine patients (42 men, 17 women; mean age 66.1 ± 17.0) who underwent 59 TAE procedures for GI bleeding during 2013–2018 were retrospectively evaluated. Clinical outcomes included technical success, adverse events, and rebleeding and mortality rate within 30 days. The technical success rate was 100%. Angiography showed contrast extravasation in 41 (69.5%) patients and indirect signs of bleeding in 16 (27.1%) patients. Two (3.4%) patients underwent prophylactic embolization. TAE-related adverse events occurred in 7 (11.9%) patients; adverse events were more common for mid GI or lower GI bleeding than for upper GI bleeding (22.6% vs 0%, P = 0.007). Rebleeding within 30 days was observed in 22 (37.3%) patients after TAE. Coagulopathy was a prognostic factor for rebleeding (odds ratio [OR] = 3.53, 95% confidence interval 1.07–11.67, P = .038). Mortality within 30 days occurred in 11 (18.6%) patients. Coagulopathy (OR = 24, 95% confidence interval 2.56–225.32, P = .005) was an independent prognostic factor for mortality within 30 days. TAE is an effective, safe, and potentially lifesaving procedure for GI bleeding. If possible, coagulopathy should be corrected before TAE as it may reduce rebleeding and mortality.

Radical Resection of Pediatric Fibrosarcoma Is Not Associated With Survival Benefit: A Nationwide Database Analysis

IntroductionFibrosarcoma is one of the most common nonrhabdomyosarcoma soft tissue sarcomas in the pediatric population. Surgical resection is the cornerstone of treatment; however, optimal factors regarding the extent of fibrosarcoma resection in localized versus regional disease is poorly understood. MethodsThe Surveillance, Epidemiology, and End Results database was queried for patients who are 19 y old or younger with a diagnosis of fibrosarcoma from 1975 to 2016. Kaplan–Meier analyses were performed for disease-specific survival on clinical and pathologic variables. Multivariate analysis was performed based on significant predictors of disease-specific survival. ResultsThere were 1290 patients (median age 13 [7-17] y) identified with fibrosarcoma. The overall survival rate at 20 y was 93%. Radical resection was performed on 22%, 40%, and 52% of patients with localized, regional, and distant Surveillance, Epidemiology, and End Results disease stage, respectively. Chemotherapy (P < 0.001), radiation (P < 0.001), histology (P < 0.001), and stage (P = 0.004) were significant predictors of increased mortality using univariate Kaplan–Meier analysis. Most patients (86%) with localized or regional stage who underwent radiation had fibrosarcomas of nondermatofibrosarcoma histology (P < 0.001). Dermatofibrosarcoma subtype comprised most radical resections (41%). Excluding distant stage, nondermatofibroma histology (hazard ratio 16.94, 95% confidence interval 3.77-76.01) and regional stage (hazard ratio 8.15, 95% confidence interval 2.93-22.69) were independent prognostic factors of mortality (both P < 0.001). Radical resection was not a significant independent prognostic indicator of survival. ConclusionsNondermatofibrosarcoma subtype is independently associated with increased mortality. Although surgery remains the mainstay of treatment, the extent of resection is not a predictor of survival for patients with the localized and regional stage of disease.
