Abstract
BACKGROUND Aflatoxin B1 (AFB1) and ochratoxin A (OTA) are among the most important mycotoxins with common presence in bread and bakery products. Biological detoxification of mould food spoilage and mycotoxin contamination by lactic acid bacteria (LABs) exhibits high potential on a cost-effective and large scale. In this work, the effect of Lactobacillus strains isolated from goat milk whey on reducing AFB1 and OTA during bread making was evaluated by the determination of mycotoxin reduction potential of 12 LAB strains after 72 h incubation in De Man-Rogosa-Sharpe (MRS) broth (37 °C). The most effective LABs were lyophilized and added as ingredient in bread formulation, analysing mycotoxins by high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry after bread fermentation and baking. RESULTS AFB1 was reduced in MRS broth by seven LABs (11-35%), highlighting Lactobacillus plantarum B3 activity; while all LABs reduced OTA (12-40%) with L. plantarum B3 and Lactobacillus paracasei B10 as the most active strains. Both LABs were lyophilized and added in contaminated bread with and without yeast, reaching AFB1 and OTA reductions up to 27% and 32% respectively in dough and up to 55% and 34% respectively in bread. CONCLUSION The selected strains significantly reduced AFB1 and OTA during bread fermentation, pointing to a potential biocontrol strategy for mycotoxins detoxification in bread and bakery products. © 2023 The Authors.

Abstract
Traditional sourdough is obtained using a mixture of flour and water stored at room temperature until acidification. Therefore, adding lactic acid bacteria (LAB) can improve the quality and safety of sourdough bread. Faced with this problem, four drying techniques-freeze-drying, spray-drying, low-temperature drying, and drying at low humidity-have been applied. Our goals were to isolate LAB strains with antifungal potential against Aspergillus and Penicillium fungi. The antifungal capacity was evaluated with agar diffusion, co-culture in overlay agar, and a microdilution susceptibility assay. In addition, the antifungal compounds generated in sourdough were analyzed. As a result, dried sourdoughs were prepared with Lactiplantibacillus plantarum TN10, Lactiplantibacillus plantarum TF2, Pediococcus pentosaceus TF8, Pediococcus acidilactici TE4, and Pediococcus pentosaceus TI6. The minimum fungicidal concentrations ranged from 25 g/L versus P. verrucosum and 100 g/L against A. flavus. A total of 27 volatile organic compounds were produced. Moreover, the lactic acid content reached 26 g/kg of dry product, and the phenyllactic concentration was significantly higher than the control. The P. pentosaceus TI6 exhibited a higher antifungal capacity in vitro and demonstrated a higher production of antifungal compounds compared to the other strains; therefore, further studies will evaluate the impact of this sourdough in bread manufacture.

Abstract
BACKGROUND There are scarce data about the efficacy and security of meal replacement products as a strategy to weight loss. AIM To evaluate the efficacy and safety of a weight loss program that includes meal replacement products. METHODS We evaluated the effect of a hypocaloric diet versus a hypocaloric diet that includes meal replacement products in 55 overweight or type I obese patients. Patients were distributed to a control group (hypocaloric diet) or an intervention group (hypocaloric diet with meal replacement products) during 8 weeks. We registered anthropometric data, smoke habit and level of physical activity. We also studied biochemical parameters at the beginning of the study, at 4th week of the study and at the end of the same. RESULTS The control group lost 3.97 kg, while in the intervention group we observed a loss of 4.44 kg. These differences were not statistically significant between groups. Other anthropometric parameters as waist and hip perimeters diminished also in both groups, without differences between them. We observed also a statistically significant decrease (p=0.041) in the values of triglycerides, without differences between groups again. DISCUSSION Meal replacement products were as effective and safe to lose weight and to modify other anthropometric parameters in a controlled dietetic program as a conventional dietetic treatment without meal replacement products.

Abstract
This survey presents the results of a poll sent to all Spanish nuclear medicine departments between July 1999 and March 2000, with the aim of clarifying the current situation of nuclear medicine in Spain. This survey is believed to be the first of its kind, and it is anticipated that the data will be of assistance to health authorities in ensuring that the needs of the population with regard to nuclear medicine facilities are met.

Abstract
BACKGROUND To compare the effectiveness of two length of the same therapy to eradicate Helicobacter pylori in patients with non complicated active peptic ulcer. PATIENTS AND METHODS 223 patients visited at primary health centres. A randomised controlled trial was carried out to compare the results of 6 or 7 days of treatment with clarithromycin 500 mg, amoxicillin 1 g and omeprazole 20 mg, b.i.d. All patients received omeprazole for other 14 days. RESULTS 108 patients were randomised to the 6 days group and 115 to the 7 days one. Both groups were comparable with respect to basic characteristics except for sex: the proportion of men was higher in the 6 days group (p = 0.04). 91.4% of the patients received all the treatment correctly. By intention to treat analysis, eradication rates were 76.9% in the 6 days group and 77.4% in the seven days group (IC 95% of the difference from -10.5 to 11.6). There were not statistically significant differences in eradication rates in relation to age, sex, ulcer location, recurrence or tobacco consumption. CONCLUSIONS Although eradication rates are lower than expected, in this study there are no differences between 6 or 7 days of therapy.

Abstract
Systemic side effects caused by parenteral pentamidine are frequent. They can be severe and life-threatening. Intravenous pentamidine may cause a variety of abnormalities in the cardiac conduction system as tachyarrhythmias, hypotension and/or non-specific ECG changes (a long corrected QT interval). There is only one case of previously reported bradyarrhythmias in an HIV-infected patient. We present a new adverse effect associated with intravenous pentamidine therapy, and to the best of our knowledge, this is the first reported case of sinus bradycardia in a patient who is not HIV-infected.

Abstract
We comment the results with non pharmacological treatment in 23 patients (mean age 11 +/- 4 years) with multiple episodes of palpitations, most of them required intravenous drugs for interrupting it. Twenty-eight procedures were performed, 17 catheter ablation and 11 surgical interventions. The energy source employed for fulguration until 1990 was DC and since 1991 radiofrequency. The best results with catheter ablation were obtained with accessory pathways. Interruption was achieved in all patients after a mean of 1.2 sessions per patient, but it was definitive in only 72%. Most of the patients (81%) remained asymptomatic without antiarrhythmic drugs. Nine patients with accessory pathways underwent surgery interruption, it was achieved in all; only one patient had arrhythmia recurrence, due to a second pathway in a different localization. We could not ablate a ectopic atrial tachycardia, that underwent surgery. There was only one indication for surgery in a patient with ventricular tachycardia. Catheter ablation does not present technical problem in children and teenagers, different from adults. The presented results lead us to suppose that the indications for non pharmacological treatment in the young will become more common.
