Abstract Background: Extracorporeal membrane oxygenation (ECMO) is often used in critical patients with severe myocardial failure. However, acute kidney injury (AKI) commonly occurs in patients on ECMO and usually brings about poor outcome. Recent studies suggest that renal vascular endothelial cell injury participates in the extent and maintenance of AKI. This study aimed to determine whether the endothelial biomarkers could serve as prognostic factors for the outcome of patients on ECMO. Methods: This prospective study enrolled total 23 critically ill patients on veno-arterial ECMO in the intensive care units of a tertiary care hospital between March 2014 and February 2015. Serum samples were tested for thrombomodulin, angiopoietin (Ang)-1, Ang-2, and vascular endothelial growth factor (VEGF). Demographic, clinical, and laboratory data were also collected. Results: The overall mortality rate was 56.5%. The combination of Ang-2 at the time of ECMO support (day 0) and VEGF at day 2 had modest prognostic ability of discriminating mortality (area under receiver operating characteristic curve [AUROC], 0.854; 95% confidence interval: 0.645-0.965). Conclusions: In this study, we found that the combination of Ang-2 at day 0 and VEGF at day 2 was a modest model for mortality discrimination in this group of patients.

Abstract Background Extracorporeal membrane oxygenation (ECMO) is often used in critical patients with severe myocardial failure. However, patients on ECMO often have high mortality rate and poor prognosis. Recent studies suggest that endothelial activation with subsequent vascular barrier breakdown is a critical pathogenic mechanism in organ damage and related to the outcome in critical illness. This study aimed to determine whether the endothelial biomarkers could serve as prognostic factors for the outcome of patients on ECMO. Methods This prospective study enrolled total 23 critically ill patients on veno-arterial ECMO in the intensive care units of a tertiary care hospital between March 2014 and February 2015.

Abstract Background Prevalence and incidence of hepatitis caused by HEV infection are usually higher in developing countries. This study demonstrated the HEV seroprevalence and incidence of HEV infection in patients with clinical hepatitis in a tertiary hospital in Thailand. Methods A laboratory-based cross-sectional study was conducted using 1106 serum samples from patients suspected of HEV infection sent to the Serology laboratory, Siriraj Hospital, for detecting HEV antibodies during 2015–2018. Prevalence of anti-HEV IgG and IgM antibodies in general patients, including organ transplant recipients and pregnant women in a hospital setting, were determined using indirect enzyme-linked immunosorbent assay (ELISA) kits. Comparison of laboratory data between groups with different HEV serological statuses was performed. Results HEV IgG antibodies were detected in 40.82% of 904 serum samples, while HEV IgM antibodies were detected in 11.75% of 1081 serum samples. Similar IgG and IgM antibody detection rates were found in pregnant women. Interestingly, anti-HEV IgM antibodies were detected in 38.5% of patients who underwent organ transplantation. Patients who tested positive for anti-HEV IgM antibodies had higher alanine aminotransferase levels than those who had not. In contrast, patients who tested positive for anti-HEV IgG had more elevated levels of total bilirubin than those who tested negative. Conclusions HEV seroprevalence and incidence in patients with clinical hepatitis were relatively high in the Thai population, including the pregnancy and organ transplant subgroups. The results potentially benefit the clinicians in decision-making to investigate HEV antibodies and facilitating proper management for patients.

Abstract Objectives: Critically ill patients requiring extracorporeal membrane oxygenation (ECMO) frequently require interhospital transfer to a center that has ECMO capabilities. Patients receiving ECMO were evaluated to determine whether interhospital transfer was a risk factor for subsequent development of a nosocomial infection. Design: Retrospective cohort study. Setting: A 425-bed academic tertiary-care hospital. Patients: All adult patients who received ECMO for >48 hours between May 2012 and May 2020. Methods: The rate of nosocomial infections for patients receiving ECMO was compared between patients who were cannulated at the ECMO center and patients who were cannulated at a hospital without ECMO capabilities and transported to the ECMO center for further care. Additionally, time to infection, organisms responsible for infection, and site of infection were compared. Results: In total, 123 patients were included in analysis. For the primary outcome of nosocomial infection, there was no difference in number of infections per 1,000 ECMO days (25.4 vs 29.4; P = .03) by univariate analysis. By Cox proportional hazard analysis, transport was not significantly associated with increased infections (hazard ratio, 1.7; 95% confidence interval, 0.8–4.2; P = .20). Conclusion: In this study, we did not identify an increased risk of nosocomial infection during subsequent hospitalization. Further studies are needed to identify sources of nosocomial infection in this high-risk population.

Clinical Benefits

OBJECTIVE Thrombotic events are potential complications in patients receiving extracorporeal membrane oxygenation (ECMO) necessitating the use of systemic anticoagulation with heparin. Heparin works by potentiating the effects of antithrombin (AT), which may be deficient in critically ill patients and can be replaced. The clinical benefits and risks of AT replacement in children on ECMO remain incompletely understood. METHODS This single-center, retrospective study reviewed 28 neonatal and pediatric patients supported on ECMO at a tertiary care hospital between April 1, 2013, and October 31, 2014, who received at least 1 dose of AT during their ECMO course. The primary outcome of the study was the change in anti–factor Xa levels after pooled human AT supplementation. Secondary outcomes included the percentage of anti–factor Xa levels within the therapeutic range surrounding AT administration; survival to decannulation; 30 days after cannulation and discharge; time to first circuit change; and incidence of bleeding and thrombotic events. RESULTS A total of 78 doses of AT were administered during the study period. The mean increase in anti–factor Xa level following AT administration in patients without a ≥10% concurrent change in heparin was 0.075 ± 0.13 international units/mL. A greater percentage of anti–factor Xa levels were therapeutic for the 48 hours following AT administration (64.2% vs 38.6%). Survival and adverse events were similar to Extracorporeal Life Support Organization averages, with the exception of a higher incidence of intracranial hemorrhage. CONCLUSIONS Patients experienced a small but significant increase in anti–factor Xa level and a greater percentage of therapeutic anti–factor Xa levels following AT supplementation.

Anastomotic Breakdown

The surgical management of children with tracheal stenosis and obstruction is complicated by the perioperative needs of pressure ventilation and indwelling endotracheal tubes. These factors predispose to surgical failure and anastomotic breakdown, restenosis, and pneumomediastinum. The use of extracorporeal membrane oxygenation (ecmo) to manage ventilation during tracheal repair allows better visualization at the surgical site and obviates the need for indwelling endotracheal tubes and high-pressure ventilation. Six children were treated with elective ecmo at a tertiary care hospital. All 6 underwent successful surgical repair, and 4 of the 6 were ultimately extubated. There were no significant complications at the surgical site. There was 1 death from postoperative complications, and 2 patients required tracheotomy. One tracheotomy was performed for upper airway obstruction secondary to retrognathia, and this patient was subsequently decannulated. Medical complications were confined to 2 patients and included sepsis, hyperbilirubinemia, seizure disorder, renal failure, intracranial hemorrhage, and hydrocephalus. Elective ecmo provides a reliable perioperative technique for airway management of children with tracheal stenosis or obstruction. This technique offers the advantage of improved visibility at the operative site and eliminates the need for high-pressure ventilation, thereby likely reducing the risk of perioperative morbidity.

Background: the present study was under taken to determine the role of CA-125 in the diagnosis of acute appendicitis (AA), to prevent its complications and also in preventing negative appendicectomies in tertiary care hospital. Methods: The study was conducted at a tertiary care and research center between 01/03/2018 to 30/06/2019. Patients admitted to the surgery department with diagnosis of AA were considered for the study. After informed consent, a, standardized history was obtained as a case Performa. Serum samples from all the cases with clinical diagnosis of AA were obtained and stored. Only the cases with histopathologically approved AA were included in the study. Cases operated for clinical diagnosis of AA, but not histopathologically proven AA was not included in the study. CA125 levels in cases with definitive diagnosis of AA were measured. Results: In present study, ROC curve analysis revealed the sensitivity of 87.27 % and specificity of 90.91 % when the CA 125 cut-off value of > 16.8 was taken to diagnose acute appendicitis. AUC was 0.911 with a standard error of 0.0292. Conclusion: In this study we have observed that CA125 showed a positive correlation with acute appendicitis, that was statistically not significant (P>0.05). We didn’t evaluate the correlation with the disease severity. We consider that CA125 can be used as a marker in acute appendicitis cases although further research is still needed.

Introduction:Pregnancy Induced Hypertension (PIH) results from imbalance between pro-angiogenic factors (VEGF & PIGF) and antiangiogenic factors (sVEGFR-1/sflt- 1)Subjects and methodology: A mixed random study comprising of random cases of different gestational ages 28-36 wks of PIH mothers along with control cases till completion of pregnancy after delivery. Age of enrolled mothers and their gestational age, blood pressure, serum free VEGF and sVEGFR-1(sflt1) were compared in both groups (control n=36, PIH n=36). Blood pressure of both control and PIH mothers just before and after delivery showed significant correlation (p<0.0001). Serum levels of free VEGF were lower among PIH mothers at 28-36 wks (p <0.0001) and just before delivery (JBD) (p <0.0001) than normal control antenatal mothers and more or less similar in both groups at just after delivery (p <0.390). Serum sflt1 level (6459.81 ±1811.07 pg/ml) of PIH mothers showed higher value than control mothers (1062.19 ± 165.98 pg/ml) at the time of presentation and also just before delivery(JBD) & after delivery(JAD) and was highly significant ( p < 0.0001). Serum free VEGF level of PIH mothers was negatively correlated with systolic r= - 0.247, p = 0.147) and diastolic (r =-0.220, p =0.197) blood pressure. The increased serum sflt1 level of PIH mothers was positively correlated with systolic (r = 0.299, p = 0.07) and diastolic (r = 0.309, p = 0.067) blood pressure. Semi quantitative expression of VEGF R1 and PCNA LI of placenta showed increased (3+) expression of VEGF R1 of 13 (43.33%) and > 50% PCNA LI expression of 12 (40%) cases than control.Discussion &Conclusion:The elevated levels of systolic and diastolic blood pressure along with alteration of proangiogenic and angiogenic growth factors among PIH mothers than normotensive control may help to identify PIH mothers as early as possible and referring them to higher/tertiary centers for better management and prevention of its grave complications of PIH.International Journal of Human and Health Sciences Vol. 02 No. 01 Jan’18.
