This study investigated the effects of dietary supplementation with inactivated Lactobacillus plantarum for Nile tilapia (Oreochromis niloticus). Three treatments, in quintuplicate, were established: a control group, fish fed a diet without additives; LP group, fish fed a diet supplemented with live probiotic; and IP group, fish fed a diet supplemented with inactivated probiotic. Final weights (49.40 ± 3.15 g) and weight gains (38.20 ± 3.23 g) were increased in tilapia in the IP group. Feed conversion (1.32 ± 0.04) decreased significantly in the IP group. Haemato-biochemical parameters were significantly influenced by dietary supplementation. Erythrocyte count (262.74 ± 69.28 × 106 μL -1 ) was significantly low, while albumin (1.79 ± 1.12 g dL -1 ) and cholesterol (254.14 ± 98.49 mg dL -1 ) were high in the control group. Dietary supplementation modified the tilapia microbiome. Rhodobacter was abundant in fish intestines from the control and IP groups. Phreatobacter was abundant in the IP and LP groups, while Aurantimicrobium and Bosea were abundant in the LP group. Oleic acid (C18:1n9) was significantly increased in the LP (3.25 ± 0.49%) and IP (3.02 ± 0.30%) groups. Hexadecatrienoic acid (C16:3n4) was significantly increased (0.04 ± 0.01%) in the IP group, while Cis 11,14,17-eicosatrienoic acid (C20:3n3) (0.31 ± 0.03%) and adrenic acid (C22:4n6) (0.11 ± 0.02%) were significantly decreased in the LP group. Additionally, monounsaturated fatty acids (MUFA) were significantly increased (4.83 ± 0.35%) in the LP group compared to that in the control group. Collectively, these results indicate the potential of inactivated L. plantarum for use in commercial feed, leading to the conclusion that both inactivated and live L. plantarum can improve the Nile tilapia metabolism, altering haematological and biochemical markers., (© 2024.

Neonaticide is an infant murder occurring on the day of birth. The case reports found in the literature are often focused on the mother as the agent in the context of pregnancy denial, dissociative symptoms, or psychosis. However, this report describes a rare case of attempted serial neonaticides, in which the acts were committed by a nurse at the nursery of a referral hospital in Brazil. The authors describe a forensic psychiatric evaluation for criminal responsibility and correlate the information from this particular case with relevant forensic themes, namely neonaticide, Munchausen by proxy syndrome, and serial healthcare killers., (© 2015 American Academy of Forensic Sciences.)

Background: Assessing the risk of violence is a complex task. In Latin America it is often based on clinical criteria that are not very objective or structured. HCR-20 has been used to increase the accuracy of this exam., Aims: The aim of this study was to examine the predictive validity of the Historical, Clinical and Risk Management Scales (HCR-20) violence risk assessment scale on a sample of Brazilian male forensic psychiatric inpatients., Method: A concurrent prospective cohort design was used. The cohort was selected among the population of inpatients in Unit D (N=68) at Instituto Psiquiátrico Forense Mauricio Cardoso (IPF), Brazil. For the baseline assessment the following instruments: HCR-20-Assessing Risk for Violence, Version 2, and Hare Psychopathy Checklist, Revised (PCL-R) were used. During the one-year follow up, episodes of violent and/or anti-social behavior were assessed, and recorded on the Yudofsky's Overt Aggression Scale (OAS) and Tengström et al.'s Follow-Up Questionnaire. The accuracy of HCR-20 and PCL-R to predict violent and/or anti-social behavior was assessed., Results and Conclusions: For the whole cohort, the mean total score of PCL-R was 13.54 and of HCR-20 it was 23.32. The rate of recidivism in the twelve month follow up was 73.5%. Outstanding among the risk factors explored for their predictive efficacy are scale HCR-20 and subscale H for any event, and scale HCR-20 for a violent event. The predictive efficacy of scales HCR-20 and PCL-R was greater for any antisocial event than for a violent event. By taking into account the possibility of recidivism and the probability of recidivism accumulated over time, instruments HCR-20 and PCL-R behaved as expected. In all these explorations, the instruments significantly differentiated the group of the sample that recidivated earlier., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Objective: Assessing risk for violence is a complex task often based on not objective or structured clinical evaluations. HCR-20 Assessing Risk for Violence has been used in several countries to increase the accuracy of this exam. The purpose of this study was to inform on central aspects of this instrument, as well as the results of the reliability assessment of the HCR-20 Assessing Risk for Violence in a Brazilian inpatient criminal population., Method: Two examiners independently assessed a random sample of 30 patients that were under criminal commitment at the Mauricio Cardoso Forensic Psychiatric Institute, Results: Mean consensus values means were as follows: Historical = 13.1; Clinical = 4.8 and Risk management = 5.8. The value of the Intraclass Correlation Coefficient for the score of subscale Historical was 0.97, for subscale Clinical it was 0.94, and for subscale Risk management, 0.96. As to the individual items of the HCR-20 Assessing Risk for Violence, the result of the Intraclass Correlation Coefficient was good to excellent (mean = 0.97; interval, from 0.60 to 0.99)., Conclusion: The interrater reliability of the Brazilian version of the HCR-20 Assessing Risk for Violence scale was similar to the results of studies in other countries.

Objective: This article describes two complex and doubly preoccupying situations in terms of public health, either, for its high prevalence and/or its consequences. These problems are the psychoactive substance use disorder and crime. The form will be told as diverse researchers associate them, as well as the situation of the exam of users and alcohol dependents and drugs., Method: A revision of publications was become fulfilled on the subject, using Medline and Lilacs as data bases, covering the period of 1986 the 2006. The keywords used had been: "Alcoholism", "drug dependence", "drug abuses" and "crime". Summaries of congresses, articles and excellent books on the subject, published for different authorities in the subject, in diverse phases of research, had been consulted and enclosed., Conclusion: The diverse research coincide in the affirmation of an association between psychoactive substances use disorders and crime. What it is possible to evidence is the high ratio of violent acts when the alcohol or the illicit drugs is used by aggressors, its victims or in both. When it carries through an expert examination in authors who allege some relation of the practiced act with alcohol consumption/drugs, this exam must take in consideration the substance in use, the clinical symptom for caused it, as well as verifying the presence of a diagnosis, the existence of causal nexus and possible alterations in the understanding capacity and/or determination of the agent.
