The medical management of MO may be effective in the short and intermediate terms, although it usually fails then leading to surgical management. Our goal is to assess Capella's surgical technique by means of quality indicators including weight loss. The present work has been performed with surgical MO patients at the 12 de Octubre University Hospital during 2000-2001, and registering the follow-up checkups for the period 2000-2001/2003-2004. We reviewed the clinical charts of 23 patients. The average Body Mass Index (BMI) was 52.24 ± 10.07 kg/m2, (range, 41.74.41). When compiling the statistical results, we observed statistically significant post-surgical decreases with no differences whether the PEIMCP outcome was excellent (≤= 65%), fair (= 50-65%) or failure (≥= 50%) in the following parameters: BMI (p ≥= 0.001); Comorbidities (p ≥= 0.001); Hemoglobinemia (p ≥= 0.005); Glycemia (p ≥= 0.001); Triglyceridemia (p ≥= 0.001); Total cholesterolemia (p ≥= 0.001); Sideraemia (p ≥= 0.001); and serum cianocobalamine (p ≥= 0.001). We could not demonstrate statistically significant changes in the remaining parameters. However, under the presumption that the lack of evidence does not mean the evidence of the absence, that is to say, the results have been obtained from a small sample (N = 23) so that they may not be considered definitely conclusive. Considering the percentage of the loss of Body Mass Index excess as one of the quality indexes in bariatric surgery, we may state that Capella's gastric by-pass is efficient in obese patients with BMI ≥ 50 kg/m2, doubtfully effective in patients with BMI 50-60 kg/m2, and ineffective in super obese patients with BMI ≥ 60 kg/m2.

During two seasons (2003-2004 and 2004-2005), from the end of October to March, the effect of applying liquid humus (HL) was evaluated on the biological, productive yields and fruit quality of tomato Amalia variety. With this aim, two experiments were carried out, totally randomized under a small farmer's production conditions from Havana province, consisting of an Eutric compacted Red Ferralitic soil, where studies of some of its physico-chemical properties were made, that offered the information of being a soil with adequate properties for a good crop development. The biological indicators evaluated are stem length and diameter, number of leaves and inflorescences, productive indicators (number and fruit weight per plant), indicators of external fruit quality (polar and equatorial diameters) and internal quality (acidity, SST, ºBrix, vitamin C, dry weight), agricultural yield (t.ha-1) and the economic analysis per each treatment. For 2004-2005 season, the infestation index as well as the social impact were evaluated based on fruit quality. Results show the sensitivity of this tomato variety before the biostimulating action of liquid humus, applied to leaves in two doses at intervals of 15 days and concentrations of 1 mL HL/30 mL and 1 mL HL/40 mL water, seven days after transplanting (ddt), increasing the biological, productive yields, quality and social impact, with productive stage reduction, under a small farmer's production conditions, they being economically feasible, mainly HL at 1/30 concentration.
