RESUMO
Diarrhea is one of the most frequent side effects of antibiotic treatment and occurs in 25 to 40% of patients in use. One potential strategy to prevent this side effect is the concurrent use of probiotics. This study evaluated the efficacy of the strain Bifidobacterium lactis CCT 7858 in the prevention of diarrhea and improvement of gastrointestinal symptoms in hospitalized patients using antibiotics. This was a randomized, blinded, placebo-controlled clinical trial. This study included 104 patients in antibiotic treatment. Patients were randomized into two groups: placebo (maltodextrin) and intervention (strain Bifidobacterium lactis CCT 7858 at 9 × 1010 CFU concentration; GABBIA® Biotecnology, Santa Catarina, Brazil). Patients were supplemented depending on the duration of antibiotic therapy, and both were evaluated with scales in two moments: before and after treatment. We included 104 hospitalized patients. In follow-up, 38 (74.5%) of the B. lactis group have no reported diarrhea. In secondary outcomes, in five day strong abdominal distension was reported in 4 (7,3) placebo group and not reported in B. lactis. Abdominal noises, nausea, and vomiting were not registered in any group. B. lactis strain has been considered safe and with several benefits, including reduction of soft stools and gastrointestinal symptoms how abdominal noise, pain and distension, as well reduction of diarrhea.

This study investigated the behavioral and biochemical parameters of DM1 as a risk factor in an animal model of schizophrenia (SZ). All groups: 1 Control (saline+saline); 2 Alloxan (alloxan+saline); 3 Ketamine (saline+ketamine); 4 (Alloxan+Ketamine) were fasted for a period of 18h before the subsequent induction of DM via a single intraperitoneal (i.p) injection of alloxan (150mg/kg). From the 4th to the 10th days, the animals were injected i.p with ketamine (25mg/kg) or saline, once a day, to induce a model of SZ and 30min after the last administration were subjected to behavioral testing. After, the animals were decapitated and the brain structures were removed. Ketamine induced hyperactivity and in the social interaction, ketamine, alloxan and the association of alloxan+ketamine increased the latency and decreased the number of contacts between animals. The animals from the ketamine, alloxan and alloxan+ketamine groups showed a prepulse startle reflex (PPI) deficit at the three intensities (65, 70 and 75dB). Ketamine was shown to be capable of increasing the activity of acetylcholinesterase (AChE) in the brain structures. Combination of alloxan+ketamine seems to have an exacerbated effect within the cholinergic system. For lipid peroxidation and protein carbonyls, alloxan+ketamine appear to have intensified lipid and protein damage in the three structures. Ketamine and the combination of ketamine+alloxan induced DNA damage in both frequency and damage index. This research found a relationship between DM1 and SZ.
