Objectives/AimsTraumatic brain injury is a common cause of permanent or long-term disability,1 and up to 80% of people with moderate to severe brain injury have some degree of pituitary insufficiency. Endocrine disruption has been documented in medical literature since the 1940s,2-4 where central diabetes insipidus has been described as a common transient complication which causes polydipsia (insatiable thirst). However, polydipsia can be caused by other conditions. It is classified into dipsogenic, in a syndrome of disordered thirst-regulating mechanism in patients without psychiatric disease called dipsogenic diabetes insipidus, psychogenic, as a compulsive water drinking in patients with psychiatric conditions referred to as psychogenic polydipsia or psychogenic diabetes insipidus and iatrogenic where large quantities of water are consumed for health benefits. All of which are referred to as primary polydipsia if these conditions cannot be distinguished. Dipsogenic diabetes insipidus and psychogenic polydipsia can be easily mixed up, misdiagnosed or even unrecognised, mainly because their pathophysiology is still unclear. Are these conditions different, or is there anything that can relate them to each other? With this literature review, we are aiming to find the link between subsets of polydipsia after brain trauma, to compare proposed differential diagnosis and their functionality in clinical settings.MethodA literature review was conducted following a search of MEDLINE, CINAHL Plus, APA PsycArticles, APA PsycBooks, APA PsycInfo databases from 1858 onwards.ResultsWe will present our findings from the literature review.ConclusionPolydipsia is a common clinical problem and requires careful evaluation and management to prevent long term neurological sequelae, and there are no evidence-based treatment guidelines.References National Institute of Health and Care Excellence (NICE).

We describe two methods of producing viable and fertile autotetraploid Pacific oyster (Crassostrea gigas Thunberg) based on the use of normal-sized oocytes produced by normal diploid females. Our methods showed that the oocyte size is not a limiting factor for the success of the induction to autotetraploidy. These methods offer means of direct introgression of genetic progress from elite diploid lines to tetraploids used as broodstock, avoiding a triploid step with the risk of transferring undesirable traits from highly fecund triploids. High variability in the level of cytogenetic stability was found among the different tetraploid oysters tested, showing that induction method has an important impact on the long-term cytogenetic stability of the tetraploids. It appears that induction method based on the use of triploid females induces a greater cytogenetic instability among tetraploids so obtained, and this compared to tetraploids originating from the two methods described in our present study. As the aneuploidies and reversions observed in tetraploids can have serious consequences for the sustainability of tetraploid broodstock itself, as well as their triploid offspring, the two tetraploid induction methods described in the present work offer means to produce tetraploids with optimal cytogenetic, genetic, and zootechnical performances.

The presence of triclosan (TCS) in water resources has drawn significant attention due to its endocrine disruption potential. Sulfate radicals (SRs), generated particularly by the metal-mediated activation of peroxymonosulfate (PMS), have been proposed to effectively decompose TCS and many other pharmaceuticals and personal care products. In spite of its significance for understanding the efficiency of SR generation and catalytic/non-catalytic nature of the oxidation reaction, metal speciation has not been adequately highlighted in previous studies. This study investigated the detailed changes in metal speciation in cobalt/PMS and iron/PMS systems and correlated it with TCS decomposition under different pH conditions. A rapid oxidation of Co2+ to Co3+ and Fe2+ to Fe3+ generally corresponded with pseudo-steady state decomposition kinetics of TCS after its initial fast decomposition. The presence of potential threshold concentrations of metals to effectively activate PMS was found. A strong catalytic activity was observed for Co/PMS system at pH 3, where most of Co was present in the form of dissolved Co2+. The pH impacts were different for Co/PMS and Fe/PMS. TCS oxidation was fast at pH 5 for Co and pH 3 for Fe. However, long-term mineralization of TCS seemed less dependent on pH.
