RESUMO

BACKGROUND: Excessive bleeding is common after cardiac surgery. According to transfusion algorithms based on ROTEM results (TEM International Inc., Munich, Germany), platelet transfusion is recommended when FIBTEM amplitude is normal and EXTEM amplitude is reduced. The aim of this study was to evaluate whether ROTEM (TEM International Inc.) parameters may predict accurately platelet counts in cardiac surgery patients, and to determine which of these parameters is the most useful for predicting platelet counts. METHODS: In this retrospective single center study data from 83 patients who underwent cardiac surgery were reviewed. We analyzed the results of patients for whom ROTEM (TEM International Inc.) and conventional laboratory tests were performed simultaneously. The derived ROTEM (TEM International Inc.) parameter PLTEM was used to estimate platelet count; PLTEM is calculated by subtracting FIBTEM from EXTEM. Correlation between ROTEM (TEM International Inc.) variables and platelet counts were determined. Logistic regression analyses were performed to predict platelet counts. RESULTS: ROTEM A5 values show a high linear correlation with MCF values. PLTEM has a strong linear correlation with platelet counts. According to our results for PLTEM A5<32 mm the probability of platelet count <150×109/L is 100%, for PLTEM A5<27 mm the probability of platelet count <100×109/L is nearly 80%, and for PLTEM A5<22 the probability of platelet count <75×109/L is 70%. CONCLUSIONS: This study demonstrates the reliability of considering early ROTEM (TEM International Inc.) results and the feasibility of using PLTEM A5 to predict platelet counts and so, improve our ability to decide the need of platelet transfusion in cardiac surgery patients.

RESUMO

Debulking surgery, followed by taxane/platinum-based chemotherapy has traditionally been the first-line treatment for advanced ovarian cancer. However, most patients will experience recurrence afterwards, and receive subsequent lines of therapy. It has been proposed that extending the treatment-free interval of platinum can improve the response to a subsequent platinum-based chemotherapy, and reduce associated toxicities in women with recurrent, platinum-sensitive ovarian cancer. The aim was to determine the impact, in clinical practice, of trabectedin with pegylated liposomal doxorubicin (trabectedin/PLD) on the subsequent platinum-based therapy in these patients, and to explore the prognosis for breast cancer gene status and the expression of diverse genes. This was a multicenter, retrospective, postauthorization study that involved 79 patients. Germline or somatic mutations of breast cancer gene 1/2 were present in 21.5%. The median time between trabectedin/PLD and the onset of the subsequent treatment was 6.7 months. The overall response rate during the trabectedin/PLD period was 36.7%. In the subsequent first-line platinum-based therapy, the overall response rate was 51.4%. Progression-free survival and overall survival were 11.8 and 25.4 months, respectively, from the onset of trabectedin/PLD treatment. Partially platinum-sensitive (between 6 and 12 months) and platinum-sensitive patients (treatment-free interval of platinum≥12 months) showed no differences in progression-free survival and overall survival. Grade 3 neutropenia and asthenia were reported in 15.2 and 10.1% of patients, respectively. Most frequent adverse events in more than 10% of patients were neutropenia (45.6%), asthenia (43.0%), nausea (25.3%), and anemia (13.9%). The intercalation with a nonplatinum regimen may improve the response to a subsequent platinum-based therapy in women with recurrent, platinum-sensitive ovarian cancer.

RESUMO

BACKGROUND: Angiogenesis is a target in the treatment of ovarian cancer. Nintedanib, an oral triple angiokinase inhibitor of VEGF receptor, platelet-derived growth factor receptor, and fibroblast growth factor receptor, has shown activity in phase 2 trials in this setting. We investigated the combination of nintedanib with standard carboplatin and paclitaxel chemotherapy in patients with newly diagnosed advanced ovarian cancer. METHODS: In this double-blind phase 3 trial, chemotherapy-naive patients (aged 18 years or older) with International Federation of Gynecology and Obstetrics (FIGO) IIB-IV ovarian cancer and upfront debulking surgery were stratified by postoperative resection status, FIGO stage, and planned carboplatin dose. Patients were randomly assigned (2:1) via an interactive voice or web-based response system to receive six cycles of carboplatin (AUC 5 mg/mL per min or 6 mg/mL per min) and paclitaxel (175 mg/m(2)) in addition to either 200 mg of nintedanib (nintedanib group) or placebo (placebo group) twice daily on days 2-21 of every 3-week cycle for up to 120 weeks. Patients, investigators, and independent radiological reviewers were masked to treatment allocation. The primary endpoint was investigator-assessed progression-free survival analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01015118. FINDINGS: Between Dec 9, 2009, and July 27, 2011, 1503 patients were screened and 1366 randomly assigned by nine study groups in 22 countries: 911 to the nintedanib group and 455 to the placebo group. 486 (53%) of 911 patients in the nintedanib group experienced disease progression or death compared with 266 (58%) of 455 in the placebo group. Median progression-free survival was significantly longer in the nintedanib group than in the placebo group (17·2 months [95% CI 16·6-19·9] vs 16·6 months [13·9-19·1]; hazard ratio 0·84 [95% CI 0·72-0·98]; p=0·024). The most common adverse events were gastrointestinal (diarrhoea: nintedanib group 191 [21%] of 902 grade 3 and three [<1%] grade 4 vs placebo group nine [2%] of 450 grade 3 only) and haematological (neutropenia: nintedanib group 180 [20%] grade 3 and 200 (22%) grade 4 vs placebo group 90 [20%] grade 3 and 72 [16%] grade 4; thrombocytopenia: 105 [12%] and 55 [6%] vs 21 [5%] and eight [2%]; anaemia: 108 [12%] and 13 [1%] vs 26 [6%] and five [1%]). Serious adverse events were reported in 376 (42%) of 902 patients in the nintedanib group and 155 (34%) of 450 in the placebo group. 29 (3%) of 902 patients in the nintedanib group experienced serious adverse events associated with death compared with 16 (4%) of 450 in the placebo group, including 12 (1%) in the nintedanib group and six (1%) in the placebo group with a malignant neoplasm progression classified as an adverse event by the investigator. Drug-related adverse events leading to death occurred in three patients in the nintedanib group (one without diagnosis of cause; one due to non-drug-related sepsis associated with drug-related diarrhoea and renal failure; and one due to peritonitis) and in one patient in the placebo group (cause unknown). INTERPRETATION: Nintedanib in combination with carboplatin and paclitaxel is an active first-line treatment that significantly increases progression-free survival for women with advanced ovarian cancer, but is associated with more gastrointestinal adverse events. Future studies should focus on improving patient selection and optimisation of tolerability. FUNDING: Boehringer Ingelheim.

RESUMO

BACKGROUND: In subjects with hypercholesterolaemia, cholesterol values remain above guideline levels. One of the limiting factors to the achievement of goals in such patients is therapeutic non-adherence. The aim of this study is to assess the effectiveness of an intervention designed to improve control of hypercholesterolaemic patients, consisting of a combined strategy that would include the delivery of printed information, treatment-compliance check cards and the dispatch of text messages as complementary measures in support of the intervention at the general practitioner's practice. METHODS/DESIGN: A randomised, parallel-group clinical trial will be conducted at the family medicine outpatient facilities of eight health centres in three of Spain's Autonomous Regions (Comunidades Autónomas), covering a total of 358 subjects aged 18 years or over with diagnosis of hypercholesterolaemia. Patients in the intervention group will be supplied with printed material with information on the disease and its management, mobile-telephone text messages with guideline summaries, reminders of forthcoming appointments and/or arrangements for making new appointments in the event of non-attendance, and self-report cards to check compliance with recommendations. Both groups -intervention and control- will receive routine recommendations from their physicians in accordance with current European clinical practice guidelines for hypercholesterolaemia and cardiovascular risk management. As regards the measurements to be made, the main variable is the proportion of subjects who attain the low density lipoprotein cholesterol levels set as a target across a follow-up period of 24 months. The secondary variables are as follows: adherence to recommendations on lifestyle and adherence to drug treatment; variation in lipid profiles and cardiovascular risk levels; appearance of cardiovascular events; physical activity; food consumption; smoking habit; anthropometric measures; blood pressure; health problems; use of hypolipidaemic agents; socio-demographic data; beliefs and expectations about preventive recommendations; and degree of satisfaction with the combined strategy. DISCUSSION: Should this intervention prove effective, a recommendation could be issued on the application of this combined strategy to subjects with hypercholesterolaemia. It is a simple, relatively inexpensive intervention. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02314663.

RESUMO

BACKGROUND: Studies have been conducted on supplementing the daily diet with plant sterol ester-enriched milk derivatives in order to reduce LDL-cholesterol levels and, consequently, cardiovascular risk. However, clinical practice guidelines on hypercholesterolaemia state that there is not sufficient evidence to recommend their use in subjects with hypercholesterolaemia. The main objective of this study is to determine the efficacy of the intake of 2 g of plant sterol esters a day in lowering LDL-cholesterol levels in patients diagnosed with hypercholesterolaemia. The specific objectives are: 1) to quantify the efficacy of the daily intake of plant sterol esters in lowering LDL-cholesterol, total cholesterol and cardiovascular risk in patients with hypercholesterolaemia; 2) to evaluate the occurrence of adverse effects of the daily intake of plant sterol esters; 3) to identify the factors that determine a greater reduction in lipid levels in subjects receiving plant sterol ester supplements. METHODS/DESIGN: Randomised, double-blind, placebo controlled experimental trial carried out at family doctors' surgeries at three health centres in the Health Area of Albacete (Spain). The study subjects will be adults diagnosed with "limit" or "defined" hypercholesterolaemia and who have LDL cholesterol levels of 130 mg/dl or over. A dairy product in the form of liquid yoghurt containing 2 g of plant sterol ester per container will be administered daily after the main meal, for a period of 24 months. The control group will receive a daily unit of yogurt not supplemented with plant sterol esters that has a similar appearance to the enriched yoghurt. The primary variable is the change in lipid profile at 1, 3, 6, 12, 18 and 24 months. The secondary variables are: change in cardiovascular risk, adherence to the dairy product, adverse effects, adherence to dietary recommendations, frequency of food consumption, basic physical examination data, health problems, lipid-lowering medication, physical activity, smoking habits and socio-demographic variables. DISCUSSION: If plant sterol ester supplements were effective a sounder recommendation for the consumption of plant sterols in subjects with hypercholesterolaemia could be made.

RESUMO

The objective is to determine the prevalence of hearing loss in people over 65 years of age, to describe the functional status of people with hearing loss and to identify the need for hearing aid use. In a cross-sectional study, a random sample of 1387 people aged 65 years and over was selected. The primary study variables were: hearing level by audiometric assessment, self-perceived hearing loss, screening for hypoacusia using the Hearing Handicap Inventory for the Elderly-Screening (HHIE-S) and physical, cognitive and emotional functional status. Using the HHIE-S it was determined that 11.3% of the subjects had severe hearing handicap. According to the Ventry/Weinstein criteria 43.6% had hearing handicap. When asked about the use of hearing aids, 4.5% of the study subjects said they used them, although 41.9% had hearing loss of 35 dB or more in their better ear. The variables associated with the need for a hearing aid were age >75 years (odds ratio=OR=3.2), ADL dependence (OR=2.7), cognitive impairment (OR=2.0), multiple health problems (OR=1.8), male sex (OR=1.6) and single/widowed (OR=1.5). In conclusion, there is a high prevalence of hearing loss associated with other functional limitations. Of those people who would benefit from a hearing aid (more than a third of people over 65 years old), 89.3% do not own one. The screening of hearing loss needs to be improved.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the safety and feasibility of extraperitoneal laparoscopic paraaortic lymphadenectomy for suspected lymph node recurrence of gynecological cancers. DESIGN: Descriptive study. SETTING: Unit of Gynecologic Oncology of an acute-care teaching hospital in Barcelona, Spain. POPULATION: Between December 2002 and October 2007, eight women underwent extraperitoneal laparoscopic paraaortic lymphadenectomy for suspected lymph node recurrence, detected by magnetic resonance image (MRI), computed tomography (CT) scan or 18F-fluorodeoxyglucose positron emission tomography (PET) scanning. The suspicious nodes were removed through an extraperitoneal laparoscopic approach. RESULTS: The median age of patients was 66.5 years (range: 54-74). The median operating time was 157.5 minutes (range: 120-240). The median blood loss was 112.5 mL (range: 50-150). The mean nodal yield was 9.4+/-4.72 (range: 1-16). There were no intraoperative or postoperative complications. The median hospital stay was two days. Histological examination revealed metastasis in seven of eight patients. CONCLUSIONS: The extraperitoneal laparoscopic paraaortic lymphadenectomy for lymph node recurrence of gynecological cancers is a safe and feasible procedure which should be considered where there is isolated involvement of retroperitoneal lymph nodes. This procedure is a minimally invasive technique that allows an excellent approach to the paraaortic lymph nodes.

RESUMO

During the last years, and coinciding with the beginning of the concomitant treatment with radio-chemotherapy, a better control of local cervical cancer has been reached, although failures in the systemic control of the illness have been more frequent. One of the main causes is not treating the illness at the level of the para-aortic lymph nodes, basically because their affectation is unknown and because imaging tests have a high percentage of false negative results. At this time, it is when laparoscopic para-aortic lymphadenectomy arises, in order to be able to know the extension of the illness better before treatment. A extraperitoneal laparoscopic approach is described in order to reduce complications derived from a possible extended irradiation. Between August 2001 and October 2007, a total of 69 patients with bulky and locally advanced cervical cancer (FIGO stages IB2, IIA > 4 cm and IIB-IVA) underwent extraperitoneal laparoscopic lymphadenectomy for surgical staging. Extraperitoneal aortic lymphadenectomy by laparoscopic approach is a technique with low morbidity. Special laparoscopic material is not required and if it is performed by a team trained in technical endoscopics it is not difficult. Radio-chemotherapy treatment began immediately after laparoscopy because of its minimal aggression.
