Comparison between a guaiac and three immunochemical faecal occult blood tests in screening for colorectal cancer
2012
Abstract Background The aim of this study was to compare the performance of the guaiac-based faecal occult blood test (G-FOBT), with that of three immunochemical faecal occult blood tests (I-FOBT) which allow automatic interpretation. Patients and methods Under the French organised screening programme, 85,149 average-risk individuals aged 50–74 participating in the third screening round, performed both the G-FOBT (Hemoccult-II test) and one of the I-FOBTs: FOB-Gold, Magstream and OC-Sensor. Results Given the chosen threshold, the positivity ratio between the different I-FOBTs and the G-FOBT was 2.4 for FOB-Gold, 2.0 for Magstream and 2.2 for OC-Sensor (P = 0.17). The three I-FOBTs were supe…
Impact of granulocyte colony-stimulating factor (G-CSF) and epoetin (EPO) on hematologic toxicities and quality of life in patients during adjuvant c…
2020
Hematologic toxicities are one of the greatest challenges in adjuvant chemotherapy for breast cancer. This analysis of the ADEBAR trial aims to evaluate application and effect of granulocyte colony-stimulating factor (G-CSF) and epoetin alfa (EPO) on hematologic parameters and fatigue in patients with breast cancer during chemotherapy.In the ADEBAR trial, 1493 patients with node-positive primary breast cancer were randomized to either 6 × 5-fluorouracil, epirubicin, and cyclophosphamide (FEC120) or 4 × epirubicin and cyclophosphamide followed by 4 × docetaxel (EC-DOC). Co-medication with G-CSF or EPO was applied to treat chemotherapy-induced leukopenia or anemia. Fatigue was assessed at bas…
Dosage individualization of erythropoietin using a profile-dependent support vector regression
2003
The external administration of recombinant human erythropoietin is the chosen treatment for those patients with secondary anemia due to chronic renal failure in periodic hemodialysis. The objective of this paper is to carry out an individualized prediction of the EPO dosage to be administered to those patients. The high cost of this medication, its side-effects and the phenomenon of potential resistance which some individuals suffer all justify the need for a model which is capable of optimizing dosage individualization. A group of 110 patients and several patient factors were used to develop the models. The support vector regressor (SVR) is benchmarked with the classical multilayer percept…
Phase I trial of recombinant human tumour necrosis factor alpha in patients with advanced malignancy.
1991
A phase I clinical trial was conducted with recombinant human tumour necrosis factor alpha (rhTNF-alpha) in 62 patients with advanced malignancy refractory to previous standard therapy. rhTNF-alpha was given as a 30 min infusion twice a day at 6 h intervals. A total of 10 different dose levels was escalated in cohorts of 6 patients ranging from 2.5 to 200 micrograms/m2 twice a day for 5 days every second week for a total of 8 weeks followed by a 4-week observation period. Major side-effects of TNF-alpha therapy, seen in almost all patients studied, were fever and chills. As dose-limiting side-effects hypotension and liver toxicity were recorded in 4 of 5 patients treated with 200 micrograms…
Epoetin alfa improves anemia and anemia-related, patient-reported outcomes in patients with breast cancer receiving myelotoxic chemotherapy: results …
2010
This study evaluated the effects of epoetin alfa on patient-reported outcomes in patients with breast cancer receiving myelotoxic chemotherapy. Early intervention with epoetin alfa was well tolerated and improved anemia-related patient-reported outcomes.
Blood rheology during chemotherapy in patients with ovarian cancer.
1998
The use of platinum based chemotherapy in ovarian malignancy and other cancer types is known to be associated with deep vein thrombosis. In a prospective study of 47 patients with ovarian cancer of International Federation of Gynecology and Obstetrics stage Ib-IV, serial rheological parameters were determined (plasma viscosity, red blood cell aggregation under conditions of stasis and low shear) in addition to hemoglobin, hematocrit, leukocytes, platelets, and fibrinogen. At the same time the incidence of deep vein thrombosis was recorded before, during six cycles of first line cisplatinum/epirubicin/cyclophosphamide chemotherapy, and 2 months thereafter (two-months check-up). Only six pati…
Higher leukocyte subpopulation counts in healthy smoker industrial workers than in nonsmoker industrial workers: possible health consequences.
2012
<b><i>Objectives:</i></b> Cigarette smoke contains free radicals, which cause injury to endothelial cells and oxidize bioactive components in the blood. Neutrophils, a subpopulation of leukocytes, contain the enzyme myeloperoxidase that mediates production of hypochlorous acid during oxidative stress. In this study, we investigated whether smoker industrial workers had significantly higher neutrophil counts than nonsmoker industrial workers. <b><i>Design and Methods:</i></b> We collected blood samples from 183 apparently healthy male and 30 female industrial workers. We obtained blood cell counts, measured the concentration of plasma aminothio…
Plasma leptin and vascular endothelial growth factor (VEGF) in normal subjects at high altitude (5050 m)
2013
Context: High altitude (HA) is a model of severe hypoxia exposure in humans. We hypothesized that nocturnal hypoxemia or acute maximal exercise at HA might affect plasma leptin and VEGF levels. Objectives: Plasma leptin, VEGF and other metabolic variables were studied after nocturnal pulse oximetry and after maximal exercise in healthy lowlanders on the 3rd-4th day of stay in Lobuche (5050 m, HA) and after return to sea level (SL). Results: Leptin was similar at SL or HA in both pre- and post-exercise conditions. Pre-exercise VEGF at HA was lower, and cortisol was higher, than at SL, suggesting that nocturnal intermittent hypoxia associated with periodic breathing at HA might affect these v…
Higher vitamin B12 levels in neurodevelopmental disorders than in healthy controls and schizophrenia
2020
Recent studies suggest that both high and low levels of vitamin B12 (vitB12) may have negative health impacts. We measured VitB12 in patients with the Neurodevelopmental disorders (ND) (n = 222), comprised of Autism Spectrum Disorders, specific Developmental disorders, and Intellectual Disability (aged 2-53 years), schizophrenia (n = 401), and healthy controls (HC) (n = 483). Age-and gender-adjusted vitB12 z-scores were calculated by comparisons with a reference population (n = 76 148). We found higher vitB12 in ND (median 420 pmol/L, mean z-score: 0.30) than in HC (316 pmol/L, z-score: 0.06, P < .01) and schizophrenia (306 pmol/L, z-score: -0.02, P < .001), which was significant after adju…
Fever of Unclear Origin and Cytopenia Because of Acute Splenic Sequestration in a Young Immunocompetent Carrier of Beta-Globin Mutation for Hb Vallet…
2008
Fever of unclear origin is a clinical challenge in medical practice. Infectious diseases, neoplasms, and collagen vascular illnesses are its main causes in adults and children. Acute splenic sequestration crises, a known potentially fatal complication of sickle cell disease and sickle beta-thalassemia, are uncommon in beta-heterozygosis. We describe a case of prolonged recurrent episodes of fever with spontaneous resolution, commencing at age 10 in a 15-year-old boy with a history of hypochromic microcytic anemia attributed to a thalassemic trait. He was admitted twice to our university hospital for continuous-remittent fever with a pruritic, macular evanescent Still's skin rash, severe spl…
