Objective: Palliative sedation is a common treatment in palliative care. The home is a difficult environment for research, and there are few studies about sedation at home. Our aim was to analyze this practice in a home setting. Method: We conducted a retrospective cross-sectional descriptive study in a home cohort during 2011. The inclusion criteria were as follows: 18 years or older and enrolled in the Palliative Home Care Program (PHCP) with advanced cancer. The variables employed were: sex, age, primary tumor location, and place of death. We also registered indication, type, drug and dose, awareness of diagnosis and prognosis, consent, survival, presence or absence of rales, painful mouth, and ulcers in patients sedated at home. We also collected the opinions of family members and professionals about the suffering of sedated patients. Results: A total of 446 patients (56% at home) of the 617 admitted to the PHCP between January and December of 2011 passed away. The typical patient in our population was a 70-year-old man with a lung tumor. Some 35 (14%) home patients required sedation, compared to 93 (49%) at the hospital. The most frequent indication was delirium (70%), with midazolam the most common drug (mean dose, 40 mg). Survival was around three days. Rales were frequent (57%) as well as awareness of diagnosis and prognosis (77 and 71%, respectively). Perception of suffering after sedation was rare among relatives (17%) and professionals (8%). In most cases, the decision was made jointly by professionals and family members. Significance of Results: Our study confirmed the role of palliative sedation as an appropriate therapeutic tool in the home environment. Copyright © Cambridge University Press 2014.

Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal neoplasms with the median age at diagnosis being in the seventh decade. If left untreated, the disease progresses to acute myeloblastic leukemia (AML). There are many options for the management of MDS, but the only potentially curative treatment is allogenic hematopoietic stem cell transplantation (allo-HSCT), which is often not an option because of advanced age or comorbidities at diagnosis or lack of a human leukocyte antigen-identical donor. MDS in the elderly should be managed similar to that in young patients, but the fact that many advanced age patients cannot undergo allo-HSCT precludes any chance of cure. Despite the main objective of prolonging overall survival and the time to progression to AML, the key is to improve quality of life for the longest possible time. To achieve these objectives, supportive care is essential. Likewise, immunomodulatory drugs, such as lenalidomide, can reduce transfusion requirements and reverse cytologic and cytogenetic abnormalities in patients with MDS with chromosome 5q deletion. Elderly patients with high-risk MDS can benefit from 5-azacitidine (5-AZA), with efficacy and safety profiles comparable with those found in patients under 75 years of age. In any patient, predictive drug response scores are required in order to ensure more rational use of these medications. © Springer Healthcare 2011.

Aim: We aimed to evaluate the amount and quality of the RNA obtained from lymph nodes of non-Hodgkin lymphomas (NHLs) patients using fine-needle aspiration cytology (FNAC), and to develop strategies to overcome eventual technical drawbacks. Materials and Methods: Twenty-six patients with NHL and 10 tonsils from children submitted to tonsillectomy underwent FNAC. The aspirates were performed using both cytoaspirator (sample A) and syringe and needle (sample B). The RNA was extracted using Trizol reagent and transcribed with the Superscript kit (Invitrogen). The quality of RNA was verified through the amplification of a β-actin 155-bp fragment. Results: Fifty-two NHL and 20 tonsil samples were analyzed. The total amount of RNA in the tonsil samples varied from <1.0 to 6.2μg with cytoaspirator (A) and from <1.0 to 4.7μg with syringe and needle (B). The total amount of RNA obtained from NHL varied from <1.0 to 6.5μg with cytoaspirator (A) and <1.0 to 5.5μg with syringe and needle. In an attempt to increase the amounts of RNA in each sample, we standardized the polyAPCR technique, which increased by 10 times the amount of cDNA in most of the test and control samples. The efficiency of the reaction was verified through the amplification of β-actin, in which 100% of the test and control samples were amplified. When polyAPCR cDNA and nonamplified cDNA samples were paired to be evaluated by real-time PCR, using glyceraldehyde-3-phosphate dehydrogenase as the constitutive gene and nuclear factor-kappa B and NFκBIA as target genes, there was equivalence in the amplifications of 100% of the 15 evaluated samples. Conclusions: Our results showed that FNAC, obtained either by cytoaspirator or syringe and needle, is a good source of small amounts of RNA. The polyAPCR technique significantly increased the amount of genomic material, which might be a cDNA source for future gene expression studies. Copyright © 2010 by Lippincott Williams & Wilkins.
