Timing of initiation of intra-aortic balloon pump in patients with acute myocardial infarction complicated by cardiogenic shock: A meta-analysis.

BackgroundFor patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) undergoing primary percutaneous coronary intervention (PCI), the optimal timing of the initiation of intra‐aortic balloon pump (IABP) therapy remains unclear. Therefore, we performed the first meta‐analysis to compare the outcomes of IABP insertion before vs after primary PCI in this population.MethodsElectronic databases of PubMed, EMBASE, and Cochrane Library were comprehensively searched from inception to April 1, 2019, to identify the eligible studies. The main outcomes were short‐term (in‐hospital or 30 days) and long‐term (≥ 6 months) mortality. In addition, pooled analysis of risk‐adjusted data were also performed to control for confounding factors.ResultsSeven observational studies and two sub‐analysis of randomized controlled trials involving 1348 patients were included. Compared to patients inserted IABP after PCI, patients who received IABP therapy before primary PCI had similar risks of short‐term (odds ratio [OR] 0.88, 95% CI 0.49 to 1.59) and long‐term (OR 0.99, 95% CI 0.58 to 1.68) all‐cause mortality. Moreover, a pooled analysis of risk‐adjusted data also found similar effects of the two therapies on short‐term (OR 0.65, 95% CI 0.34 to 1.25) and long‐term (OR 0.68, 95% CI 0.17 to 2.72) mortality. Besides, no significant difference was found between the two groups with respect to reinfarction, repeat revascularization, stroke, renal failure, and major bleeding.ConclusionsThe timing of the initiation of IABP therapy does not appear to impact short‐term and long‐term survival in patients with AMI complicated by CS undergoing primary PCI.

Next-Generation Sequencing May Discriminate Extreme Long-term versus Short-term Survival in Patients with Metastatic Small Cell Lung Cancer (SCLC)

BACKGROUND: Molecular underpinnings that may prognosticate survival could increase understanding of small cell lung cancer (SCLC) tumor behavior. Here, we report the clinicopathological characteristics and biomarker profiles of short-term (ST) versus long-term (LT) survival in patients with metastatic SCLC. METHODS: Of the 876 consecutive metastatic SCLC patients receiving standard of care therapy, 44 met the definition of LT and 91 for ST, respectively. Available FFPE tumor tissue blocks were analyzed by next-generation sequencing (NGS). Analysis included gene mutations, copy number variations, mRNA expression, and protein expression by immunohistochemistry, followed by correlation with clinicopathological characteristics. RESULTS: There were no statistically significant and clinically relevant differences in cases with or without FFPE according to major clinicopathological variables in ST and LT. However, according to NGS, five mutually exclusive gene mutations were identified (E1A binding protein P300 [EP300] p.N217S; p.E152K; human epidermal growth factor receptor 4 [ERBB4] p.E317K; BRCA1, DNA repair associated [BRCA1] p.E1661N, and epidermal growth factor receptor [EGFR] p.V742A). Comparing LT vs. ST survivals, a twofold increase was found in the average predicted number of drugs per patient off compendium. We found high SSTR2 mRNA expressions in all LT patients (vs. two [20%] ST patients), which may reflect more benign neuroendocrine tumor characteristics. CONCLUSIONS: Consolidation radiation therapy and higher predicted drug sensitivity for off compendium were associated with LT compared to ST patients in SCLC. NGS profiling of extreme survivals may improve classification of SCLC and possibly identify clinically relevant new targets.

Evaluation of 30 Day Readmissions After Index Ventricular Assist Device Implantation in the United States.

Ventricular assist device (VAD) implantation has improved quality of life and short-term survival for advanced heart failure patients. There are limited data from single-center studies addressing the characteristics and etiologies of 30 day readmissions after VAD implant. We used the Nationwide Readmissions Database (NRD) 2014 to identify insertion of implantable heart assist system during index admission. Primary and secondary outcomes were 30 day readmissions and leading etiologies, respectively. We analyzed 1,481 patients who received VAD during the primary admission of whom 1,315 patients survived to hospital discharge (mortality rate 11.2%), and 60.6% were discharged to a nursing facility. One hundred and thirty-one (10.0%) patients were readmitted within 30 days of primary hospitalization. Leading etiologies of 30 day readmission were bleeding (24%), heart failure (18%), and device complications (14%). Mean length of stay during readmission was 13.8 days with a mortality rate of 2.1%. Fifty percent of 30 day readmissions were readmitted from day 22 to 30. Variables for predictors of 30 day readmissions were not statistically significant. By identifying gastrointestinal bleeding, heart failure, and device complications as leading etiologies of 30 day readmission post-VAD implantation, providers can potentially modify practices to prevent hospital readmissions, decreasing cost of care, and improving the quality of life of patients.

Visceral Fat Volume From Standard Preoperative CT is an Independent Predictor of Short-term Survival in Patients Undergoing Surgery for Metastatic Spine Disease.

This is a retrospective cohort. Determine the relationship of body morphometry to postoperative survival in patients with vertebral metastases. Most operations for vertebral metastases aim for palliation not cure, yet expected patient survival heavily influences treatment plans. We seek to demonstrate that preoperative fat and muscle volumes on standard-of-care computed tomography (CT) are independent predictors of survival after surgery for vertebral metastases. Included data were preoperative neurological status, adjuvant treatments, CT-assessed body composition, health comorbidities, details of oncologic disease, and Tomita and Tokuhashi scores. Body composition-visceral fat area, subcutaneous fat area, and total muscle area-were assessed on preoperative L3/4 CT slice with Image J software. Multivariable logistic regressions were used to determine independent predictors of 3-, 6-, and 12-month survival. We included 75 patients (median age, 57, 57.3% male, 66.7% white) with the most common primary lesions being lung (17.3%), prostate (14.7%), colorectal (12.0%), breast (10.7%), and kidney (9.3%). The only independent predictor of 3-month survival was visceral fat area [95% confidence interval (CI): 1.02-1.23 per 1000 mm; P=0.02]. Independent predictors of survival at 6 months were body mass index (95% CI: 1.04-1.35 per kg/m; P=0.009), Karnofsky performance status (95% CI: 1.00-1.15; P<0.05), modified Charlson Comorbidity Index (95% CI: 1.11-7.91; P=0.03), and postoperative chemotherapy use (95% CI: 1.13-4.71; P=0.02). Independent predictors of 12-month survival were kidney primary pathology (95% CI: 0.00-0.00; P<0.01), body mass index (95% CI: 1.03-1.39 per kg/m; P=0.02), and being ambulatory preoperatively (95% CI: 1.28-17.06; P=0.02). Visceral fat mass was an independent, positive predictor of short-term postoperative survival in patients treated for vertebral metastases. As a result, we believe that the prognostic accuracy of current predictors may be improved by the addition of visceral fat volume as a risk factor.

Utility of Prognostic Prediction Models in the Terminal Stage of Gastrointestinal Cancer.

For patients receiving palliative care, information about prognosis is important to help them set priorities and expectations for care and to assist clinicians in decision-making. The purpose of this study was to investigate prognostic models applicable to the terminal stage of gastrointestinal cancer, especially in terms of accuracy of prediction regarding 3-week survival. We validated retrospectively the accuracy of a prognosis prediction model for 354 end-stage gastrointestinal cancer patients who underwent palliative care at our hospital. Using receiver operating characteristic analysis and the area under the curve (AUC), we selected the cut-off value for 3-week survival and evaluated the predictive ability using sensitivity, specificity, positive predictive value, negative predictive value, and accurate diagnosis rate. In our analysis of various models, Palliative Prognostic Index (PPI) and Biological Prognostic Score (BPS) version 3 showed excellent predictive performance with AUCs of 0.85 and 0.83, respectively, and accurate diagnosis rates of 80.0 and 79.0, respectively. BPS version 2 showed fair predictive performance with an AUC of 0.76 and an accurate diagnosis rate of 72.0. Using these models, stratification of prognostic prediction was possible. PPI and BPS were found to be accurate prediction models for short-term survival of terminal gastrointestinal cancer patients.

Predictive Capacity of Risk Models in Liver Transplantation.

Several risk models to predict outcome after liver transplantation (LT) have been developed in the last decade. This study compares the predictive performance of 7 risk models. Data on 62 294 deceased donor LTs performed in recipients ≥18 years old between January 2005 and December 2015 in the United Network for Organ Sharing region were used for this study. The balance of risk, donor risk index (DRI), Eurotransplant-DRI, donor-to-recipient model (DRM), simplified recipient risk index, Survival Outcomes Following Liver Transplantation (SOFT), and donor Model for End-stage Liver Disease scores were calculated, and calibration and discrimination were evaluated for patient, overall graft, and death-censored graft survival. Calibration was evaluated by outcome of high-risk transplantations (>80th percentile of the respective risk score) and discrimination by concordance index (c-index). Patient survival at 3 months was best predicted by the SOFT (c-index: 0.68) and Balance of Risk score (c-index: 0.64), while the DRM and SOFT score had the highest predictive capacity at 60 months (c-index: 0.59). Overall, graft survival was best predicted by the SOFT score at 3-month follow-up (c-index: 0.65) and by the SOFT and DRM at 60-month follow-up (c-index: 0.58). Death-censored graft survival at 60-month follow-up is best predicted by the DRI (c-index: 0.59) and Eurotransplant-DRI (c-index: 0.58). For patient and overall graft survival, high-risk transplantations were best defined by the DRM. For death-censored graft survival, this was best defined by the DRI. This study shows that models dominated by recipient factors have the best performance for short-term patient survival. Models that also include sufficient donor factors have better performance for long-term graft survival. Death-censored graft survival is best predicted by models that predominantly included donor factors.

Increased Serum Soluble Urokinase Plasminogen Activator Receptor Predicts Short-Term Outcome in Patients with Hepatitis B-Related Acute-on-Chronic Liver Failure.

Aims Soluble urokinase plasminogen activator receptor (suPAR) reflects the immune activation in circumstances of inflammation and infection. It has been considered as a risk biomarker associated with poor outcome in various low-grade inflammation and infectious diseases. The study is aimed at investigating whether suPAR has a predictive value with short-term survival in patients with hepatitis B-related acute-on-chronic liver failure (HB-ACLF). Methods Serum suPAR expression was compared among patients with different states of chronic hepatitis B virus infection. Sixty HB-ACLF patients were recruited as the training cohort and followed up for 90 days. Serum suPAR level and the clinical relevance with short-term outcome were investigated. The temporal dynamics of suPAR were evaluated in 50 HB-ACLF patients with available serum sequentially at baseline, week 2 and week 4. Another 167 HB-ACLF patients were enrolled to validate the predictive value of suPAR with respect to the prognosis. Results Serum suPAR level was significantly increased in HB-ACLF patients compared to non-ACLF patients. In the training set of HB-ACLF, we observed higher suPAR level, INR, MELD score, and more complications in nonsurvivors than survivors. Longitudinal analysis revealed an increased trend of suPAR level in nonsurvivors during week 0 to week 4 and the modest decline in survivors. It showed that the synchronous suPAR level was higher in nonsurvivors at all indicated time points. Elevated suPAR level at baseline was identified as a strong predictor of a 90-day mortality of HB-ACLF patients. It was confirmed suPAR > 16.26 ng/ml had a positive predictive value of 72.22% and a negative predictive value of 77.88% for poor outcome in the validation cohort. Conclusions Serum suPAR level increases significantly in HB-ACLF patients and associated with a 90-day mortality. It suggests that suPAR might be a potential biomarker to predict the prognosis of HB-ACLF patients.

Effects of oxaliplatin-containing adjuvant chemotherapy on short-term survival of patients with colon cancer in Dr. Sardjito Hospital, Yogyakarta, Indonesia.

Oxaliplatin-based adjuvant chemotherapy has been applied as standard treatment for high risk stages II and III colon cancer in many countries. There was no comprehensive report of oxaliplatin use in Indonesia. This research aimed to evaluate the short-term survival of patients with colon cancer treated with such strategy and the prognostic factors. Medical records of patients with colon cancer receiving oxaliplatin-containing adjuvant chemotherapy were retrospectively reviewed. Demography, clinicopathological, and treatment data were collected. Two-year overall survival (OS) and disease-free survival (DFS) were calculated using Kaplan-Meier method and survival predictors were estimated using Cox proportional hazard models. Data of 81 patients had been included with a median follow-up of 25.2 months. The estimated OS and DFS at 2 years were 75.8% and 72.7%. In multivariate analyses, the Eastern Cooperative Oncology Group (ECOG) 2 performance status [hazard ratio (HR) =2.967; 95% confidence interval (CI), 1.265 to 6.957; P=0.012], T4 stage (HR =2.669; 95% CI, 1.087 to 6.557; P=0.032), and less cycles of chemotherapy administration (HR =3.280; 95% CI, 1.333 to 8.070; P=0.010) were significant independent factors for an increased risk of death. Cases with moderately to poorly differentiated tumors had significantly worse DFS compared with those with well differentiated tumors (HR =3.503; 95% CI, 1.403 to 8.744; P=0.007). Colon cancer patients receiving oxaliplatin-based adjuvant regimens in our clinical practice had 2-year OS rate of 75.8% and 2-year DFS rate of 72.7%. ECOG 2 performance status, T4 stage, and less cycles of chemotherapy administration significantly predicted a poor OS and moderately to poorly histological grade significantly predicted a poor DFS.

Impact of body mass index on short-term and long-term survival in prevalent hemodialysis patients.

Numerous studies showed that higher body mass index (BMI) is associated with better survival in hemodialysis (HD) patients. Most of them evaluated short-term mortality. It has been suggested that presence of inflammation may be a key modifier of relationship between BMI and mortality in incident HD patients. We examined whether presence of inflammation modifies the association between BMI and mortality in both short-term and long-term follow-up in a large group of prevalent HD patients. A total of 3.252 HD patients from 41 HD centers were enrolled; the patients were divided into quartiles based on time-averaged BMI (Q1 < 21.5, Q2 21.5 to <24.3, Q3 24.3 to <27.4, Q4 ≥ 27.4 kg/m2 ). Inflammation status was defined as present (inflamed) (C-reactive protein (CRP) ≥1.0 mg/dL and/or serum albumin ≤3.5 g/dL) or absent (noninflamed). During 7 years of follow-up 1386 patients (42.6%) died. Compared to noninflamed patients, inflamed patients in the lowest BMI quartile showed 5-fold increased risk for mortality in the short-term (95% confidence interval [CI] 2.82-9.22, P < 0.001) and 3-fold in the long-term (95%CI 2.42-4.27, P < 0.001) compared to the highest BMI quartile. Whereas, inflamed patients in the highest BMI quartile experienced 2-fold increased risk in short-term (95%CI 1.17-3.74, P = 0.01) and 1.68-fold increased risk in long-term (95%CI 1.30-2.18, P < 0.001) than in noninflamed patients. The protective effect of BMI for overall mortality was present in all age groups, in both genders, in patient with and without diabetes. BMI was not a mortality predictor in patients with HD duration more than 76 months at baseline. The protective effect of BMI was observed in all albumin tertiles. In patients in the lowest CRP tertile, BMI was not associated with mortality. Higher BMI is associated with lower short-term and long-term mortality risk, especially in patients with inflammation in a prevalent HD population.

Alcohol abuse and disorder of granulopoiesis.

Granulocytes are the major type of phagocytes constituting the front line of innate immune defense against bacterial infection. In adults, granulocytes are derived from hematopoietic stem cells in the bone marrow. Alcohol is the most frequently abused substance in human society. Excessive alcohol consumption injures hematopoietic tissue, impairing bone marrow production of granulocytes through disrupting homeostasis of granulopoiesis and the granulopoietic response. Because of the compromised immune defense function, alcohol abusers are susceptible to infectious diseases, particularly septic infection. Alcoholic patients with septic infection and granulocytopenia have an exceedingly high mortality rate. Treatment of serious infection in alcoholic patients with bone marrow inhibition continues to be a major challenge. Excessive alcohol consumption also causes diseases in other organ systems, particularly severe alcoholic hepatitis which is life threatening. Corticosteroids are the only therapeutic option for improving short-term survival in patients with severe alcoholic hepatitis. The existence of advanced alcoholic liver diseases and administration of corticosteroids make it more difficult to treat serious infection in alcoholic patients with the disorder of granulopoieis. This article reviews the recent development in understanding alcohol-induced disruption of marrow granulopoiesis and the granulopoietic response with the focus on progress in delineating cell signaling mechanisms underlying the alcohol-induced injury to hematopoietic tissue. Efforts in exploring effective therapy to improve patient care in this field will also be discussed.

Approaches for patients with very high MELD scores.

SummaryIn the era of the “sickest first” policy, patients with very high model for end-stage liver disease (MELD) scores have been increasingly admitted to the intensive care unit with the expectation that they will receive a liver transplant (LT) in the absence of improvement on supportive therapies. Such patients are often admitted in a context of acute-on-chronic liver failure with extrahepatic failures. Sequential assessment of scores or classification based on organ failures within the first days after admission help to stratify the risk of mortality in this population. Although the prognosis of severely ill cirrhotic patients has recently improved, transplant-free mortality remains high. LT is still the only curative treatment in this population. Yet, the increased relative scarcity of graft resource must be considered alongside the increased risk of losing a graft in the initial postoperative period when performing LT in “too sick to transplant” patients. Variables associated with poor immediate post-LT outcomes have been identified in large studies. Despite this, the performance of scores based on these variables is still insufficient. Consideration of a patient’s comorbidities and frailty is an appealing predictive approach in this population that has proven of great value in many other diseases. So far, local expertise remains the last safeguard to LT. Using this expertise, data are accumulating on favourable post-LT outcomes in very high MELD populations, particularly when LT is performed in a situation of stabilization/improvement of organ failures in selected candidates. The absence of “definitive” contraindications and the control of “dynamic” contraindications allow a “transplantation window” to be defined. This window must be identified swiftly after admission given the poor short-term survival of patients with very high MELD scores. In the absence of any prospect of LT, withdrawal of care could be discussed to ensure respect of patient life, dignity and wishes.

Development of a model based on case-mix analysis to predict 6-month patient survival after liver transplantation: a multicenter Italian study

Short-term patient survival (PS) after liver transplantation (LT) is predicted by MELD score. This SITO-AISF study aimed to identify, besides the MELD score, factors predicting 6- and 12-month PS after LT, in order to develop case-mix models. Primary endpoint was 6-month PS; secondary end-points were 6-month graft survival and 12 month PS. LT was considered futile if associated with 5 years PS < 50% and/or 6 months PS < 60%.

Risk Factors for Early Graft Failure and Death After Kidney Transplantation in Recipients Older Than 70 Years

IntroductionAlthough kidney transplantation carries a survival benefit compared with dialysis, mortality, especially the first year after transplantation, is high in recipients older than 70. The aim of this study was to evaluate early death and graft failure, and to determine the risk factors associated with these events in this specific population.MethodsAll patients older than 70 years who received a kidney transplant between January 2000 and December 2014 in the North-West of France were included (n = 171). Baseline characteristics and outcomes after transplantation were studied. Kaplan-Meier analysis was performed to assess patient and graft survival, and Cox regression analysis to evaluate risk factors for graft failure and patient death.ResultsThe mean recipient age was 73.3 ± 2.5 years. Death-censored graft survival at 1, 3, and 5 years were 82.6%, 78.7%, and 75.4%, respectively. Patient survival at 1, 3, and 5 years was 90.1%, 82.5%, and 68.1%, respectively. One year after transplantation, 17 patients (9.9%) were dead, mainly from infectious (58.5%) or cardiovascular disease (29.4%). According to the Cox multivariate analysis, the independent risk factors for death or graft failure during the first year were arrhythmia (odds ratio [OR] 2.26; 95% confidence interval [CI] 1.08–4.8), left-ventricular ejection fraction (LVEF) under 56% (OR 2.38; 95% CI 1.18–4.83), human leucocyte antigen (HLA) antibodies (OR 2.1; 95% CI 1.04–4.2), deceased donor from cardiovascular cause (OR 5.18; 95% CI 1.22–6.3), and acute rejection (OR 2.77; 95% CI 1.2–6.3).ConclusionIn kidney transplant recipients older than 70 years, cardiac evaluation and immunosuppression optimization seem to be crucial to improve short-term patient and graft survival.

Predictors of De Novo Nonalcoholic Fatty Liver Disease After Liver Transplantation and Associated Fibrosis.

Nonalcoholic fatty liver disease (NAFLD) can occur de novo in patients undergoing liver transplantation (LT) for indications other than NAFLD, and it has been increasingly recognized as a complication in the post-LT setting. This study aims to better characterize de novo NAFLD after LT by identifying risk factors for its development, describing incidence and extent of fibrosis, assessing the diagnostic utility of noninvasive serum fibrosis algorithms, and comparing survival to those without NAFLD. This was a retrospective single-center analysis of de novo NAFLD in a post-LT cohort. Those whose primary indication for LT was nonalcoholic steatohepatitis (NASH) were excluded. Risk factors were analyzed by univariate and multivariate analyses. De novo NAFLD and fibrosis were assessed on posttransplant liver biopsies, and noninvasive fibrosis scores were calculated from concomitant blood tests. After applying the exclusion criteria, 430 for-cause post-LT biopsies were evaluated; 33.3% (n = 143) had evidence of de novo steatosis and/or NASH at a median of 3.0 years after transplant. On multivariate analysis, body mass index (BMI; odds ratio [OR], 1.12; P < 0.001), diabetes mellitus (OR, 3.01; P = 0.002), hepatitis C virus (OR, 4.61; P < 0.001), weight gain (OR, 1.03; P = 0.007), and sirolimus use (OR, 3.11; P = 0.02) were predictive of de novo NAFLD after LT. Significant fibrosis (≥F2) was present in almost 40% of the cohort. Noninvasive serum fibrosis scores were not useful diagnostic tests. There was no significant difference in the short-term or longterm survival of patients who developed de novo NAFLD. In conclusion, diabetes, BMI, weight gain after LT, and sirolimus-based immunosuppression, in keeping with insulin resistance, were the only modifiable factors associated with development of de novo NAFLD. A significant proportion of patients with de novo NAFLD had fibrosis and given the limited utility of noninvasive serum fibrosis algorithms, alternative noninvasive tools are required to screen for fibrosis in this population. There was no significant difference in the short-term or longterm survival of patients who developed de novo NAFLD.

The value of ascitic fluid calprotectin and calprotectin-to-albumin ratio in the diagnosis and prognosis of spontaneous bacterial peritonitis

Introduction Spontaneous bacterial peritonitis (SBP) is a potentially fatal condition, characterized by infection of ascitic fluid (AF) in the absence of any intra-abdominal surgically treatable source of infection. It is the most frequent and severe complication of cirrhotic ascites. SBP is a condition that requires a high index of suspicion, rapid and accurate diagnosis, in addition to prompt and effective therapy. Aim The aim of this study was to evaluate AF calprotectin as a diagnostic marker in detecting SBP. In addition, we have evaluated AF calprotectin-to-albumin ratio in the diagnosis and prognosis of SBP. Patients and methods A total of 72 patients with cirrhotic ascites were included in this study. They were divided into two groups: SBP group included 50 patients with cirrhotic ascites and SBP diagnosed by presence of polymorphonuclear leukocyte count at least 250 cells/mm3 in AF with or without positive AF culture, and non-SBP group included 22 patients with cirrhotic ascites without evidence of SBP. All patients were subjected to complete clinical evaluation, laboratory investigations, diagnostic abdominal paracentesis, serum and AF C-reactive protein levels, which were assessed quantitatively, and AF calprotectin levels, which were measured by quantitative sandwich enzyme-linked immunosorbent assay. Results AF calprotectin was significantly elevated in patients with SBP in comparison with non-SBP patients (P&lt;0.001), with the best cutoff value for the detection of SBP (372 ng/ml) with a sensitivity, specificity, positive predictive value, negative predictive value, and an accuracy of 100% for each. Moreover, there was a positive correlation with total leukocytic count, polymorphonuclear leukocyte, and C-reactive protein in serum and AF. Moreover, calprotectin-to-albumin ratio was increased in SBP group versus non-SBP group (P&lt;0.001). Conclusion AF calprotectin can be used as a valuable marker in rapid diagnosis of SBP. Moreover, calprotectin-to-albumin ratio in ascites is useful in the diagnosis of SBP, as well as it provides prognostic information on short-term survival of patients with SBP with follow-up treatment.

Short-Term Survival of Ischemic Stroke Patients

Background: Identification of factors associated with short-term survival of ischemic stroke patients (survival <30 days). Research Objectives: to analyze the relationship of blood pressure, pulse, respiratory frequency, GCS, instantaneous blood sugar, LDL cholesterol and triglycerides, history of hypertension, history of diabetes mellitus and a history of heart disease. Method: This study used an observational analytic method with a retrospective design. Sampling uses purposive sampling. 258 samples were taken from medical record data from January 2016 - December 2017. Results: Blood pressure, level of consciousness, momentary base sugar levels, triglycerides and history of DM that were significantly associated with the dependent variable (survival) in ischemic stroke patients. This can be seen from the ?-value variable systolic blood pressure (? = 0.001) and diastolic blood pressure variable (? = 0.000), Awareness Level (GCS) (? = 0.000), instantaneous blood sugar (? = 0.015), triglycerides ( ? = 0.033), and history of DM (? = 0.005). Conclusion: Ischemic stroke factors that are significantly related to short-term survival are blood pressure level of consciousness, instantaneous basic sugar levels, triglycerides and history of DM

Does LC3 have a role in colorectal carcinoma of Egyptian patients?

Background and aim In Egypt, colorectal cancer (CRC) constitutes 4.2% and comes at rank seventh in men and fourth in women. Autophagy is considered an intracellular homeostatic pathway that is related to cancer and other diseases. The role of autophagy with CRC carcinogenesis and tumor progression is uncertain. LC3 is a specific marker for autophagy. The aim of this study is to evaluate the role of autophagy markers LC3A and LC3B in CRC. Materials and methods This retrospective case–control study included 158 colorectal specimens including 87 chemo-naive CRC cases, 12 adenomas, and 59 nonneoplastic colonic tissue cases from Egyptian patients; all cases were stained for LC3A and LC3B antibodies. Results LC3A showed significant epithelial and stromal expression in nonneoplastic colon cases (P=0.02 and 0.015, respectively). There were significant associations between LC3A epithelial overexpression and low-grade CRC cases and long survival (P=0.01 and 0.016, respectively). There was no significant association between LC3B epithelial and stroma expression with histopathological parameters or between three groups. Conclusion The low expression of LC3A could be incriminated in the pathogenesis of CRC and short-term overall survival in Egyptian patients. However, LC3B might be considered as a surrogate marker in our study.

Mixture cure model for estimating short-term and long-term colorectal cancer survival.

We used mixture cure mode to separately investigate the risk factors for long-term and short-term survival of colorectal cancer patients. Colorectal cancer (CRC) is the second most common cancer worldwide. In cancer studies, patients' survival is the most important indicator of patients' status. Classical methods in analyzing the survival data usually apply Cox proportional hazard regression. The study was performed on 1121 patients diagnosed with colorectal cancer. Mixture cure model with Weibull distribution and logit link function was fitted to data. Odds of long-term survival for rectum cancer patients were lower than for colon cancer patients (OR=0.29(0.09, 0.9)). Also, patients with the advanced stage of the disease had lower odds of long-term survival compared to early-stage patients (OR=0.24(0.06, 0.86)).In the short-term, the hazard of death for people with normal BMI was lower than the underweight group (HR=0.4(0.21, 0.76)). The short-term hazard of death for rectum cancer was about half of the short-term hazard for colon cancer (HR=0.49(0.29, 0.81)). Further, people with moderately (HR=2.11(1.26, 3.55)) and poorly (HR=4.04(2.03, 8.03)) differentiated tumor grade had a higher short-term hazard of death compared to people with well-differentiated grade. Predictive variables of colorectal cancer survival showed different effects in short- and long -terms. Site topography was a prognosis for both long-term and short-term survival; BMI and tumor grade were short-term predictors of survival while stage was a long-term predictor of survival.
