Use of Venetoclax in Patients with Relapsed or Refractory Acute Myeloid Leukemia: The Pethema Registry Experience

2020

Introduction The prognosis of patients with recurrent or refractory acute myeloid leukemia (AML-RR) is very poor, especially if they are not candidates for allogeneic transplantation (allo-SCT) after a second complete response (CR). Venetoclax, a potent and selective inhibitor of the antiapoptotic protein BCL-2, was approved by the FDA in combination with hypomethylating agents (HMAs) or low-dose cytarabine (LDAC) in patients with newly diagnosed AML of age ≥ 75 years, or who have comorbidities that preclude the use of intensive chemotherapy. However, the evidence in AML-RR patients is still scarce. For this reason, the objective of our study is to retrospectively analyze the efficacy of th…

In vivo metabolism of LDL subfractions in patients with heterozygous FH on statin therapy

2004

LDL can be subfractionated into buoyant (1.020-1.029 g/ml(-1)), intermediate (1.030-1.040 g/ml(-1)), and dense (1.041-1.066 g/ml(-1)) LDLs. We studied the rebound of these LDL-subfractions after LDL apheresis in seven patients with heterozygous familial hypercholesterolemia (FH) regularly treated by apheresis (58 +/- 9 years, LDL-cholesterol = 342 +/- 87 mg/dl(-1), triglycerides = 109 +/- 39 mg/dl(-1)) and high-dose statins. Apolipoprotein B (apoB) concentrations were measured in LDL subfractions immediately after and on days 1, 2, 3, 5, and 7 after apheresis. Compartmental models were developed to test three hypotheses: 1) that dense LDLs are derived from the delipidation of buoyant and in…

Dietary cholate increases plasma levels of apolipoprotein B in mice by posttranscriptional mechanisms

2001

To induce atherogenesis in mice, a high fat (HF) diet is supplemented with cholic acid (CA), which increases apoB-containing particles and lower apoA-I-containing particles. HF diet without CA increases levels of both HDL and LDL, suggesting that CA may be responsible for the elevation of LDL and lowering of HDL. The mechanism of dietary CA-induced lowering of apoA-I-containing particles has recently been reported. In this study, we examined the mechanism of CA- and HF-induced elevation of apoB-containing lipoproteins in mice. Mice were fed the following four diets: control chow (C), high fat high cholesterol, (HF), control and 0.5% cholate (CA), and HF + CA. Dietary CA increased the plasma…

Why Do Subjective Vertigo and Dizziness Persist over One Year after a Vestibular Vertigo Syndrome?

2009

The overlap and interlinkage of dizzy symptoms in patients with psychiatric and vestibular vertigo/dizziness disorders is the subject of an ongoing debate. In a one-year follow up in 68 patients with vestibular vertigo syndromes, the persistency of vertigo and dizziness symptoms was examined and correlated with vestibular parameters and results from a psychiatric evaluation. Patients with vestibular migraine showed poorest improvement of vertigo and dizziness symptoms over time. In addition, patients who developed anxiety or depressive disorder after the onset of the vestibular disorder showed poor improvement and high persistency of symptoms.

CHOP Improves Response Rates but Not Overall Survival in Follicular and Mantle Cell Lymphoma (MCL)- Results of a Randomized Trial of the German Low G…

2004

Abstract In advanced stage follicular lymphoma conventional chemotherapy is non-curative and no major improvement in overall survival has been achieved by different regimens. Similarly, MCL, a lymphoma subtype with an especially poor clinical outcome, cannot be cured by conventional chemotherapy. In 1996, the German Low Grade Lymphoma Study Group (GLSG) started a randomized trial to evaluate the efficacy of two different anthracycline/anthrachinon containing regimens comparing CHOP (cyclophosphamide 750 mg/m2 day 1, vincristine 1.4 mg/m2 day 2, adriamycine 50 mg/m2 day 1, prednisone 100 mg/m2 days 1–5) and MCP (mitoxantrone 8 mg/m2 days 1–2, chlorambucil 3x3 mg/m2 days 1–5; prednisone 25 mg…

Ofatumumab (OFA) in Combination with CHOP for Previously Untreated Follicular Lymphoma: Follow-up Results

2012

Abstract Abstract 1632 Background: OFA is a fully human monoclonal antibody that binds to both the large and small extracellular loops of CD20. OFA is currently approved for patients (pts) with refractory chronic lymphocytic leukemia and has demonstrated activity in non-Hodgkin's lymphomas, including follicular lymphoma (FL). We previously reported results of a phase II study of OFA in combination with CHOP (cyclophosphamide 750 mg/m2, doxorubicin 50 mg/m2, vincristine 1.4 mg/m2, prednisone 100 mg daily for 5 days) chemotherapy (O-CHOP) in pts with previously untreated FL (Czuczman et al. Br J Haematol. 2012;157:438). We now report updated efficacy, safety and pharmacokinetic (PK) follow-up…

EQ-5D-3L for Assessing Quality of Life in Older Nursing Home Residents with Cognitive Impairment

2020

Background: Quality of life (QoL) is recognized as an important patient-reported outcome measure. Assessing QoL in older people with cognitive impairment is a challenge due to discrepancies in the collection of data via proxies versus self-report. This study aimed to assess the psychometric properties of the self-reported EQ-5D (including the EQ index and EQ visual analog scale (VAS)) in nursing homes residents with cognitive impairment and to analyze its validity based on scales included in the comprehensive geriatric assessment. Methods: Cross-sectional, multicenter study analyzing the feasibility, acceptability, reliability, and validity of the EQ-5D based on 251 self-administered questi…

Vulvo-vaginal atrophy: A new treatment modality using thermo-ablative fractional CO2 laser.

2015

a b s t r a c t Objective: To evaluate the efficacy and feasibility of thermo-ablative fractional CO2 laser for the treatment of symptoms related to vulvo-vaginal atrophy (VVA) in post-menopausal women. Methods: From April 2013 to December 2013, post-menopausal patients who complained of one or more VVA-related symptoms and who underwent vaginal treatment with fractional CO2 laser were enrolled in the study. At baseline (T0) and 30 days post-treatment (T1), vaginal status of the women was evaluated using the Vaginal Health Index (VHI), and subjective intensity of VVA symptoms was evaluated using a visual analog scale (VAS). At T1, treatment satisfaction was evaluated using a 5-point Likert …

OP0062-HPR Efficacy of Tailored Exercise Therapy in Patients with Knee Osteoarthritis and Comorbidity: A Randomized Controlled Trial

2016

Background Exercise therapy is a key intervention in the management of knee osteoarthritis (OA). It is an effective intervention to improve physical functioning and reduce joint pain in patients with knee OA. Comorbidity, which is highly prevalent in OA, interferes with the application of exercise therapy and contributes to non-adherence to exercise therapy. Objectives To evaluate the efficacy and safety of tailored exercise therapy on physical functioning in patients with knee osteoarthritis (OA) and comorbidity Methods A randomized clinical controlled trial was performed, comparing comorbidity-adapted exercise therapy with a control intervention. The study was conducted in an outpatient r…

2020

Gait variability observed in step duration is predictive of impending adverse health outcomes among apparently healthy older adults and could potentially be evaluated using wearable sensors (inertial measurement units, IMU). The purpose of the present study was to establish the reliability and concurrent validity of gait variability and complexity evaluated with a waist and an ankle-worn IMU. Seventeen women (age 74.8 (SD 44) years) and 10 men (73.7 (4.1) years) attended two laboratory measurement sessions a week apart. Their stride duration variability was concurrently evaluated based on a continuous 3 min walk using a force plate and a waist- and an ankle-worn IMU. Their gait complexity (…
