Notes

Upsetting activities, emotional signs, and also hostility in female and male inmates.
Different evolutionary interests between males and females can lead to the evolution of sexual dimorphism. However, intersex genetic correlations due to the shared genome can constrain the evolution of sexual dimorphism, resulting in intra-locus sexual conflict. One of the mechanisms resolving this conflict is sex linkage, which allows males and females to carry different alleles on sex chromosomes. Another is a regulatory mutation causing sex-biased gene expression, which is often mediated by gonadal steroids in vertebrates. How do these two mechanisms differ in the contributions to the resolution of intra-locus sexual conflict? The magnitude of sexual conflict often varies between the juvenile and adult stages. Because gonadal steroids change in titre during development, we hypothesized that gonadal steroids play a role in sexual dimorphism expression only at certain developmental stages, whereas sex linkage is more important for sexual dimorphism expressed throughout life. Our brain transcriptome analysis of juvenile and adult threespine sticklebacks showed that the majority of genes that were sex-biased in both stages were sex-linked. The relative contribution of androgen-dependent regulation to the sex-biased transcriptome increased and that of sex linkage declined in adults compared to juveniles. The magnitude of the sex differences was greater in sex-linked genes than androgen-responsive genes, suggesting that sex linkage is more effective than androgen regulation in the production of large sex differences in gene expression. Overall, our data are consistent with the hypothesis that sex linkage is effective in resolving sexual conflict throughout life, whereas androgen-dependent regulation can contribute to temporary resolution of sexual conflict.Aims and objectives The purpose of this study was to explore opioid use disorder (OUD) education programs presented to practicing nurses working in medical-surgical settings and identify the methods used to evaluate their effectiveness. Background Health professionals often express negative attitudes towards patients with OUD which can lead to suboptimal care. Education decreases negative attitudes of healthcare workers. Despite this, few educational programs are offered to promote knowledge among acute care nurses who work in medical-surgical settings and provide care to patients with OUD. Design An integrative review METHODS The framework by Whittemore and Knafl was used to examine empirical literature between 1995-2019 to answer the research questions, 1) What types of education do acute care nurses receive regarding OUD? 2) What methods are used for measuring educational intervention effectiveness? CINAHL, ERIC, PsycINFO and MEDLINE were searched using combinations of search terms and PRISMA guidelines. Tute care nurses would promote health equity in practice for individuals with OUD.Background and aims Ketamine is used for anaesthesia, sedation and the treatment of mood disorders, but also widely used for non-medical purposes. This study aimed to 1. determine the characteristics and circumstances of all recorded cases of self-administered ketamine-related death in Australia, 2000-2019 and 2. determine the toxicology and major organ pathology of cases. Design Retrospective study of all Australian cases in which self-administered ketamine was a mechanism contributory to death, retrieved from the National Coronial Information System. Setting Australia-wide CASES 68 cases, with a mean age of 35.2 years (SD 11.5, range 16-63) and 76.5% male. Measurements Information was collected on cause of death, demographics, circumstances of death, toxicology and major organ pathology. Findings Death was attributed to toxicity in 82.3% of cases (accidental 58.8%, deliberate 23.5%), suicide by violent means (8.8%) and traumatic accident (8.8%). In six cases the decedent had been prescribed ketamine. In 32.4% the final route of ketamine administration was by injection. The fatal incident predominately occurred in a private environment (72.1%). Ketamine was present in the blood of 90.1%, being detected in other biomarkers in 9.9%. The median blood ketamine concentration was 0.2 mg/L (0.02-6.9mg/L). Other drugs were detected in 95.5% of cases opioids (59.1%), hypnosedatives (57.6%), psychostimulants (50.0%), alcohol (27.3%), Δ-9-THC (18.2%), antidepressants (28.8%), antipsychotics (9.1%). Pulmonary oedema was present in 82.2% of cases that underwent autopsy and pneumonia in 26.7%. Conclusions The typical case of self-administered ketamine-related death in Australia, 2000-2019, was a male in his mid-thirties who had used multiple drugs, with the fatal incident most commonly occurring in a private setting. Death due to accidental drug toxicity was the most common manner of death, but suicide was highly prevalent.The aim was to build a prognostic model to stratify patients at diagnosis into different risk categories. We investigated the prognostic value of functional PET parameters and clinical features in 64 primary breast lymphoma (PBL) patients. With a median follow-up of 60 months, 5-year progression-free survival (PFS) and overall survival (OS) was 62.5% and 73.4%. In multivariate analysis, baseline total metabolic tumor volume (TMTV0) and β2-microglobulin remained more reliable predictors of survival than other prognostic factors. The optimal TMTV0 cut-off value was 90 cm3 . Among 29 patients with high TMTV0, 5-year PFS and OS were 44.8% and 62.1%, respectively, while 5-year PFS and OS of 35 patients with low TMTV0 were 74.3% and 85.7%, respectively. TMTV0 combined with β2-microglobulin identified three groups with very different prognosis, including low-risk group with low TMTV0 and β2-microglobulin≤normal (n = 30), intermediate-risk group with high TMTV0 or β2-microglobulin>normal (n = 20), and high-risk group with high TMTV0 and β2-microglobulin>normal (n = 14). In the three groups, 5-year PFS rates were 80%, 55% and 28.6% (P = 0.003), and 5-year OS rates were 90%, 65% and 50% (P = 0.023) respectively. We established a new prognostic model through TMTV0 and β2-microglobulin, and can divide PBL at diagnosis into different risk categories. This article is protected by copyright.
