Symptoms of starvation in eating disorder patients
The presence of starvation symptoms should always be evaluated in eating disorder patients. The weight must be completely restored before carrying out an accurate assessment of the psychological functions and personality of eating disorder patients. Eating disorder patients should be educated that the maintenance of dietary restriction and underweight is associated with severe physical and psychosocial impairment. Since starvation symptoms are potent mechanisms maintaining eating disorder psychopathology, the treatment of underweight eating disorders should always address underweight and dietary restriction
The treatment of limb soft tissue sarcoma with TNF-alfa and pegylated liposomal doxorubicin (PLD): Phase I-II study
A prospective clinical study for molecular intra-operative detection of lymph node metastasis in breast cancer patients by one step nucleic acid amplification (OSNA) in comparison to intensive histological investigation
Prognostic Factors Influencing Tumor Response, Locoregional Control and Survival, in Melanoma Patients with Multiple Limb In-transit Metastases Treated with TNF alpha-based Isolated Limb Perfusion
Background: In isolated limb perfusion (ILP) with tumor necrosis factor-alpha (TNF alpha) and interferon (IFN)-gamma, pioneered by Lienard and Lejenne in 1988, TNF alpha was empirically employed at a dosage (3-4 mg) ten times higher than the systemic maximum tolerable close (MTD). We previously conducted a phase I/II study in 20 patients with in-transit melanoma metastases, using a combination of melphalan and TNF alpha at dosages ranging from 0.5 to 3.3 mg. The dose of 1 mg of TNFa was identified as optimal in terms of both efficacy and toxicity. The aim of the present study was to describe our experience with 113 stage IIIA/IIIAB melanoma patients treated with a TNF alpha-based ILP and identify prognostic factors for response, locoregional control and survival. Patients and Methods: Patients at stage IIIA-IIIAB (presence of in-transit metastases and/or regional node involvement) were considered eligible. The disease was bulky (>= 10 nodules :53 cm or fewer nodules with a diameter > 3 cm) in 42.5% of the patients and unresectable in 33%. Forty patients were treated with a TNFa dosage of > 1 mg and 73 with 1 mg. Patients with tumors in the tipper and lower limbs were submitted to ILP via axillary and iliac vessels, respectively. TNF alpha was injected in the arterial line of an extracorporeal circuit at the pre-established close, followed by melphalan (13 and 10 mg/l of limb volume for the upper and lower limbs, respectively) 30 minutes later. Results: Complete responses (CR) and partial responses (PR) were 63% and 24.5%, respectively, with an objective response (OR) of 87.5%. No change (NC) was observed in only 12.5% of the patients. Upon multivariate analysis, only bulky disease maintained its independent value for tumor response with an odds ratio of 4.07 and a p-value of 0.02. The 5-year locoregional disease-free survival was 42.7%. Upon multivariate analysis, the only prognostic factors were stage, age and bulky disease. The 5-year overall survival was 49%. Multivariate analysis showed that only, sex, stage and CR maintained their independent values. Conclusion: TNF alpha-based ILP was proven to be an effective treatment for melanoma patients with in-transit metastases. The TNF alpha dosage of 1 mg was as effective as 3-4 mg, with lower toxicity and cost. We propose that TNF alpha and melphalan-based ILP should be employed for bulky tumors or after failure of melphalan-based ILP
Efficacy and safety of low-dose aspirin in polycythemia vera
BACKGROUND: The use of aspirin for the prevention of thrombotic complications in polycythemia vera is controversial. METHODS: We enrolled 518 patients with polycythemia vera, no clear indication for aspirin treatment, and no contraindication to such treatment in a double-blind, placebo-controlled, randomized trial to assess the safety and efficacy of prophylaxis with low-dose aspirin (100 mg daily). The two primary end points were the cumulative rate of nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes and the cumulative rate of nonfatal myocardial infarction, nonfatal stroke, pulmonary embolism, major venous thrombosis, or death from cardiovascular causes. The mean duration of follow-up was about three years. RESULTS: Treatment with aspirin, as compared with placebo, reduced the risk of the combined end point of nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes (relative risk, 0.41; 95 percent confidence interval, 0.15 to 1.15; P=0.09) and the risk of the combined end point of nonfatal myocardial infarction, nonfatal stroke, pulmonary embolism, major venous thrombosis, or death from cardiovascular causes (relative risk, 0.40; 95 percent confidence interval, 0.18 to 0.91; P=0.03). Overall mortality and cardiovascular mortality were not reduced significantly. The incidence of major bleeding episodes was not significantly increased in the aspirin group (relative risk, 1.62; 95 percent confidence interval, 0.27 to 9.71). CONCLUSIONS: Low-dose aspirin can safely prevent thrombotic complications in patients with polycythemia vera who have no contraindications to such treatment
Body mass index and complications following major gastrointestinal surgery: A prospective, international cohort study and meta-analysis
Aim Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major postoperative complications in an international cohort and to present a metaanalysis of all available prospective data. Methods This prospective, multicentre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma or formation of stoma. The primary end-point was 30-day major complications (Clavien\u2013Dindo Grades III\u2013V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis was used to analyse pooled results. Results This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese vs normal weight patients (13.0% vs 16.2%, respectively), but this did not reach statistical significance (P = 0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. Individual patient meta-analysis demonstrated that obese patients undergoing surgery formalignancy were at increased risk of major complications (OR 2.10, 95% CI 1.49\u20132.96, P < 0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46\u20130.75, P < 0.001) compared to normal weight patients. Conclusions In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease
