Purpose: The standard endpoint for lower limb revascularization is long-term patency; however, in high-risk patients with end-stage ischemia, healing of chronic ulcerations has been proposed as an acceptable endpoint. To evaluate if today's minimally invasive interventions, in combination with comprehensive wound healing procedures, can resolve nonhealing wounds, we performed a retrospective review of chronic ulceration patients treated at the San Francisco Wound Care Center. Methods: Eight-five patients with 96 limbs at risk due to nonhealing ulcers were treated with a variety of endovacular procedures: 7 patients (group 1) received PalmazR stents for unilateral iliac occlusions; 42 limbs (group II) in 39 patients were treated with balloon angioplasty for superficial femoral and popliteal lesions; and 47 extremities in 39 patients (group III) underwent rotational atherectomy for tibioperoneal lesions. Comprehensive wound management techniques, including the application of growth factors, were used. Results: All group I wounds healed, although 6 of 7 patients required additional procedures to address outflow lesions. In groups II and III, primary patencies were similar (64% and 70%, respectively), and nine treated sites reoccluded in each group. Restenotic lesions were retreated in both groups (three in group II and four in group III); secondary patencies were 71% and 78%, respectively. There were more amputations in group III patients (five) compared to group II (one). In both groups after 5 months, 90% of wounds had healed in group II and 72% in group III. Conclusion: The use of endovascular procedures appears to play an important role in the healing of chronic lower extremity ulcerations in high-risk patients with end-stage ischemia.

Abstract Recently, cord blood transplantation (CBT) for adult is rapidly increasing in number, Especially for the patients over 50 years of age. By the end of 2003, 224 units were shipped for the patients Group I: <15 y.o. 39%, Group II: 15~50 y.o.40% and Group III :> 50 y.o.21%. We analyzed 152 patients with hematological malignancies including ALL, AML, CML, MDS, malignant lymphoma, myeloma and neuroblastoma reported from CBT center in the world by the end of 2003. Patients and Methods:Group I included 58 patients with 13 standard risk and 45 high risk patients and showed mean±SD of age; 5.3 ±4.1y.o.,BW; 20.5±13.4kg, CB volume at collection; 91.6±27.1ml, NC; 5.5±3.3x107/kg, CFC; 8.6±6.4x104/kg, CD34; 1.5±1.1x105/kg, Group II: 64 cases with 25 standard and 39 high risk patients and age; 30.6±10.3y.o., BW; 51.9±9.5kg, CB volume at collection;116.6±27.7ml, NC;2.6±0.7x107/kg, CFC;5.2±2.6x104/kg and CD34;0.8±0.5x105/kg, Group III: 30 cases with 9 standard and 21 high risk patients and age; 54.1±3.3y.o., BW;55.9±11.0kg, CB vol.at collection;118.8±24.7ml NC;2.4±0.4x107/kg, CFC;4.8±1.9x104/kg and CD34;0.8±0.4x105/kg. The patients who underwent CBT for graft failure (GF) of prior transplant were excluded. Conditioning regimen in Group I demonstrated 54 patients with full regimen and 4 with reduced intensity regimen (RIST); in Group II, 62 patients with full regimen and 2 RIST; and in Group III, 14 cases full regimen and 15 cases RIST. Results: Cumulative myeloid engraftment was seen 67.2% in Group I, 73.4% in Group II and 46.7% in Group III (*Group II vs. Group III: P<0.05). Overall survival /EFS on day 100 showed 73.4%/59.4% in Group I, 74.0%/58.6% in Group II and 43.3%/34.5% in Group III (*Group III vs. others: P<0.05). In Group III, the survival rate indicated 42.8% in full regimen group and 13.3% in RIST group at 1year after CBT. In Group I, four patients died of GF, 13 of relapse, 11 of Transplantation related disease (TRD); in Group II, 5 patients died of GF, 8 of TRD, 10 of relapse. In Group III, four patients died of TRD, 3 of GF and 3 of relapse in full regimen, while in RIST, six patients died of TRD, 1 of relapse and 1 of acute GVHD. Conclusion: The application of CBT has been expanded to the elderly patients (>50 y.o.), although the conditioning regimen and the special medical care for the complications in the early pahse after UCBT has remained to be discussed.

Background: Post-partum hemorrhage prevention (PPH) is considered a major issue due to its effect on maternal morbidity and mortality. The objective of this study was to compare efficacy of Carbetocin in prevention of atonic post-partum hemorrhage in high risk patients undergoing elective caesarean section in comparison to Oxytocin and Misoprostol.Methods: 150 pregnant women prepared for elective caesarean section were classified into 3 groups; Group I (50 patients received Carbetocin 100 mg I.V infusion), Group II (50 patients received 20 IU of Oxytocin infusion on 1000 ml of normal saline solution) and Group III (50 cases received Misoprostol 400 µg per rectum immediately before induction of anaesthesia). Assessment of PPH and its degree was determined according to amount of blood loss during and for first 24 hours of caesarean delivery, also further need for haemostatic measures were also assessed.Results: There was a statistically significant difference in PPH among the three groups 6, 14 and 12% for group I, II and III respectively (P <0.001), major PPH was 0, 4 and 6% for the same groups respectively (P <0.001). The need for additional uterotonic agents was significantly lesser in Group I compared to Group II and III (2% versus 8 and 12% respectively P = 0.02) also the need for additional surgical measures was significantly lesser among the three groups (P= 0.00). The drop in Hb level and haematocrit value was significantly lesser in group I compared to group II& III (P <0.05). The need for blood transfusion was significantly lesser in Group I compared to group II and III (0% versus 12% p <0.0001)Conclusions: Carbetocin was superior to Oxytocin and Misoprostol in prevention of atonic PPH in high risk patients underwent elective caesarean delivery. Carbetocin should be administered for all cases undergoing elective CS and carry a risk factor for postpartum hemorrhage.

Abstract: The aim of this study was to evaluate the lung maturity of premature and full-term lambs by analyzing amniotic fluid using the following methods: Clements test, Nile blue cytology test, hematoxylin-Shorr stain, lamellar body count, and radiographic tests. The use of these methods is intended to identify high-risk newborns and provide immediate clinical intervention after birth. Altogether, 56 animals (24 ewes and 32 lambs) were included in the study and divided into 3 groups. Group I consisted of 8 ewes that were at approximately 145 days of gestation; this group delivered 10 lambs naturally. Group II consisted of 8 ewes that were at 138 days’ gestation; this group delivered 11 lambs by cesarean section. Group III consisted of 8 ewes at 138 days’ gestation; this group was administered intramuscular dexamethasone (16mg/animal) 36 hours prior to a cesarean section. Group III delivered11 lambs. Cytological tests were performed using a microscope with a maximum magnification of 1000x, while the Clements test was visually observed by one of the researchers. Amnioticfluid lamellar body counts were measured using transmission electron microscopy. Among the staining methods, hematoxylin-Shorr was reliable, and Group III had a greater number of orangeophilic cells when compared to Group II, probably due to corticoid administration. The Clements test showed pulmonary maturity in approximately 20% of Group I lambs and Group II showed 9.1% of bubbles; however, Group III had the highest pulmonary maturity percentage (36.4%). The lamellar bodies were measured, and all groups had sizes between 0.019 and 0.590μm. Radiographic evaluation revealed that the majority of lambs presented some level of pulmonary radiodensity, indicating an acinar pattern at birth. These results are in line with the expectations of each group. We found that the normal group showed greater pulmonary maturity, whereas Group II presented pulmonary immaturity, which is expected because this group comprised lambs born prematurely and Group III showed pulmonary maturity almost comparable to the normal delivery group (Group I). This is due to the fact that although these animals are premature, the use of dexamethasone helped in pulmonary maturation. Therefore, these pulmonary maturity tests are considered effective when more than one technique is used and can be used routinely in the care of a pregnant ewe in labor, where a simple collection of amniotic fluid can predict a high-risk pregnancy and alert the veterinarian if the newborn needs intensive supportive treatment.

Background With increasing use of tranexamic acid in total hip and knee arthroplasties, safety concerns remain. Using national claims data, this study examined tranexamic acid use in patients with preexisting comorbidities. The hypothesis was that tranexamic acid use is not associated with increased complication risk in hip and knee arthroplasty patients with comorbidities. Methods Among 765,011 total hip/knee arthroplasties (2013 to 2016, Premier Healthcare claims), tranexamic acid use was assessed in three high-risk groups: group I with patients with a history of venous thromboembolism, myocardial infarction, seizures, or ischemic stroke/transient ischemic attack (n = 27,890); group II with renal disease (n = 44,608); and group III with atrial fibrillation (n = 45,952). The coprimary outcomes were blood transfusion and new-onset “composite complications” (venous thromboembolism, myocardial infarction, seizures, and ischemic stroke/transient ischemic attack). Associations between tranexamic acid use and outcomes were measured separately by high-risk group. The odds ratios and Bonferroni-adjusted 99.9% CIs are reported. Results Overall, 404,974 patients (52.9%) received tranexamic acid, with similar frequencies across high-risk groups I (13,004 of 27,890 [46.6%]), II (22,424 of 44,608 [50.3%]), and III (22,379 of 45,952 [48.7%]). Tranexamic acid use was associated with decreased odds of blood transfusion in high-risk groups I (721 of 13,004 [5.5%] vs. 2,293 of 14,886 [15.4%]; odds ratio, 0.307; 99.9% CI, 0.258 to 0.366), group II (2,045 of 22,424 [9.1%] vs. 5,159 of 22,184 [23.3%]; odds ratio, 0.315; 99.9% CI, 0.263 to 0.378), and group III (1,325 of 22,379 [5.9%] vs. 3,773 of 23,573 [16.0%]; odds ratio, 0.321; 99.9% CI, 0.266 to 0.389); all adjusted comparisons P &lt; 0.001. No increased odds of composite complications were observed in high-risk group I (129 of 13,004 [1.0%] vs. 239 of 14,886 [1.6%]; odds ratio, 0.89, 99.9% CI, 0.49 to 1.59), group II (238 of 22,424 [1.1%] vs. 369 of 22,184 [1.7%]; odds ratio, 0.98; 99.9% CI, 0.58 to 1.67), and group III (187 of 22,379 [0.8%] vs. 290 of 23,573 [1.2%]; odds ratio, 0.93; 99.9% CI, 0.54 to 1.61); all adjusted comparisons P &gt; 0.999. Conclusions Although effective in reducing blood transfusions, tranexamic acid is not associated with increased complications, irrespective of patient high-risk status at baseline.

Hypertension is a cardiovascular (CV) disease with high risk for CV morbid events (ME) that benefits from anti-hypertensive therapy. Resting blood pressure (BP) >140/90 mmHg serves as the diagnostic criterion for hypertension, and management has been aimed at BP reduction. Progression of CV disease in the absence of elevated blood pressure identifies individuals who might benefit from CV-protective therapy but are not currently being recognized as in need of treatment. In 2017 asymptomatic individuals evaluated for early functional and structural CV abnormalities, 1534 not taking anti-hypertensive drugs were available to determine the relationship between office blood pressure and the severity of CV abnormalities, as defined by a 10-test non-invasive disease score (DS) of 0-20. Previous studies have documented the high predictive value of DS for future CVME. The population was 53% male, average age 50±11 years, BP 122/77mmHg, LDL cholesterol 129±38 mg/dL, HDL 52±17mg/dL, triglycerides 109 mg/dL. DS was adjusted by eliminating the score for BP, but 9-test DS was still directly related to BP: 2.3 in those (n=550) <120/80 mmHg (Group I), 3.2 in those 120-129/80-85 mmHg (n=600) (Group II), 4.1 in those 130-139/85-89 mmHg (n=236) (Group III), and 5.7 in those 140+/90+mmHg (n=148) (Group IV). Nonetheless, DS of >6 indicative of high risk was present in 10% of Group I, 20% of Group II and 30% of Group III. BP was largely overlapping in individuals with no CV disease (DS 0-2), early disease (DS 3-5) and advanced disease (DS 6+). Therefore, reliance on resting BP leaves many at-risk individuals undiagnosed and untreated for early CV disease likely to progress. The hypertensive state exists in the absence of elevated BP and should be recognized and treated to prevent CVME.

Acute kidney injury (AKI) is associated with cardiovascular mortality and morbidity especially in high-risk patients undergoing cardiac surgery. It ranges from 7.7% to 28.1% in different studies. The aim of this study was to compare cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) with Creatinine as an early marker for acute kidney injury in geriatrics. From 2013 through 2015, 307 consecutive high-risk elderly patients older than 70 years undergoing emergency coronary artery bypass grafting using extracorporeal circulation were studied. All patients underwent diagnostic coronary angiography and the surgical procedure within 1 week in single hospital stay and were randomized according to timing of interval between coronary angiographyand cardiac procedure as follows: group I, less than 2 days; group II, between 2 and 4 days; and group III, higher than 4 days. Renal function was analyzed by serum cystatin C, NGAL, and creatinine. Blood samples were obtained from each patient at five time points: basal value before operation, in the four hours after operation, and on the first, third, and fifth postoperative days. Glomerular filtration rate (GFR) was calculated by Cockcroft-Gault (CG). A total of 56 patients developed postoperative acute kidney failure according to the risk, injury, and failure; and loss; and end-stage kidney disease classification. Perioperative fluid requirements, urine output, and vasopressor need during and after cardiopulmonary bypass were similar. 30-day mortality in groups was higher in group I than group II and group III (P = 0.025). AKI was least prominent in group III compared to group I and group II (P = 0.001) and expectedly, postoperative dialysis requirement was least common in group III (15, 16.66%). Patients in group III had the most favorable clinical outcome with regards to the length of ICU and hospital stay. Overall serum creatinine, cystatin C, and urine NGAL levels changed significantly throughout the entire length of following-up period in group I and group II, but not in group III. Changes in serum levels of cystatin, creatinine, and creatinine clearance were prominent in later than 24 hours. Urinary NGAL was the first variable to rise in the immediate postoperative period. Cystatin GFR was a more rapid marker than serum creatinine GFR to show acute kidney injury in three groups was a significant marker.

Purpose Patients with localized, grossly resected, or gross residual (orbital only) embryonal rhabdomyosarcoma (ERMS) had 5-year failure-free survival (FFS) rates of 83% and overall survival rates of 95% on Intergroup Rhabdomyosarcoma Study Group (IRSG) protocols III/IV. IRSG D9602 protocol (1997 to 2004) objectives were to decrease toxicity in similar patients by reducing radiotherapy (RT) doses and eliminating cyclophosphamide for the lowest-risk patients. Patients and Methods Subgroup A patients (lowest risk, with ERMS, stage 1 group I/IIA, stage 1 group III orbit, stage 2 group I) received vincristine plus dactinomycin (VA). Subgroup B patients (ERMS, stage 1 group IIB/C, stage I group III nonorbit, stage 2 group II, stage 3 group I/II) received VA plus cyclophosphamide. Patients in group II/III received RT. Compared with IRS-IV, doses were reduced from 41.4 to 36 Gy for stage 1 group IIA patients and from 50 or 59 to 45 Gy for group III orbit patients. Results Estimated 5-year FFS rates were 89% (95% CI, 84% to 92%) for subgroup A patients (n = 264) and 85% (95% CI, 74%, 91%) for subgroup B patients (n = 78); median follow-up: 5.1 years. Estimated 5-year FFS rates were 81% (95% CI, 68% to 90%) for patients with stage 1 group IIA tumors (n = 62) and 86% (95% CI, 76% to 92%) for patients with group III orbit tumors (n = 77). Conclusion Five-year FFS and OS rates were similar to those observed in comparable IRS-III patients, including patients receiving reduced RT doses, but were lower than in comparable IRS-IV patients receiving VA plus cyclophosphamide. Five-year FFS rates were similar among subgroups A and B patients.

Corn silk (Stigma maydis) contains compounds that play a role in wound healing, such as flavonoids, saponins, tannins. This study aims to formulate a gel from corn hair extract and see its activity in healing burns. The test group was divided into four groups: group I (hot metal induction), group II (without extract ), group III (corn hair extract concentration 5%), and group IV (comparison B®), which metal induction. The parameters observed were % wound healing, epithelialization time, and histopathology. The results of the study on the average% of burns healing rate 7, 14 and 21 days, namely group I (27,92%; 62,42%; 100%), group II (35,39%; 60,16%; 100%), group III (44,05%; 63,69%; 100%) and group IV (32,81%; 66,48%; 100%). The mean time of tissue peeling epithelialization groups I, II, and III was on day 16, and group IV was on day 17. For the histopathological results, the mean score of collagen fibers, fibroblast cells, and epithelialization was respectively group I (2,2; 2,7; 2), group II (2,8; 2,9; 2), group III (3,3; 2,9; 2,7), and Group IV (3,9; 3; 3). The results of the two-way ANOVA statistical test on % burn healing (p> 0.05) and one-way ANOVA at the time of epithelialization (p> 0.05) and the histopathological score (p <0.05) showed that group III (the corn hair extract 5 %) could influence the process of healing burns. Keywords: Burns, Corn Silk Extract (Stigma maydis), % Burn Healing, Epithelialization Time, Histopathology

Background: The results of cardiac surgery in patients with end-stage-liver-disease (ESLD) are poor. Concomitant cardiac surgery and orthotopic liver transplantation (OLT) may be an alternative treatment strategy in these patients. Methods: Between 2001 and 2018, eight patients underwent concomitant cardiac surgery and OLT (Conc_OLT) in our institution. We analyzed their preoperative, intraoperative and postoperative data and compared them to seven high risk patients with ESLD who underwent isolated cardiac surgery (Iso_Surg). Results: The two groups were not significantly different in terms of gender and age (Conc_OLT: 5 males, 55 ± 15 years, Iso_Surg: 4 males, 60 ± 10 years). Causes for ESLD were primary biliary cirrhosis (Conc_OLT = 1, Iso_Surg = 1), alcoholism (Conc_OLT = 2, Iso_Surg = 2), viral hepatitis (Conc_OLT = 2, Iso_Surg = 2), cryptogenic (Conc_OLT = 2, Iso_Surg = 1), ischemic (Conc_OLT = 1) and hepatocellular carcinoma (Iso_Surg = 1). Model for End-stage-Liver-Disease (MELD) Score (Conc_OLT = 14, Iso_Surg = 13) and Child-Pugh Score (Conc_OLT = 9.5, Iso_Surg = 8) were not significantly different between the two groups. Median logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) was 9.5% (Conc_OLT) and 7.1% (Iso_Surg). Cardiac procedures undertaken were aortic valve replacement (Conc_OLT = 6, Iso_Surg = 3), coronary bypass grafting (Conc_OLT = 1,Iso_Surg = 2), tricuspid valve repair (Conc_OLT = 1), combined aortic and mitral valve replacement (Iso_Surg = 1) and excision of atrial myxoma (Iso_Surg = 1). Median length of in-hospital-stay was longer in the Conc_OLT group (73 vs. 42 days; p = 0.11). At 3 months, in-hospital mortality was 25% in the Conc_OLT group (n = 2) and lower compared to 71% observed in the Iso_Surg group (n = 5, p = 0.13). Conclusion: Concomitant cardiac surgery and OLT is a promising alternative compared to isolated cardiac surgery in high risk patients with ESLD. Given the high operative mortality of cardiac surgery in patients with ESLD, the complex peri-operative management of these patients should be performed in an interdisciplinary team with an expert team of liver specialists involved.
