Queensland psychiatrists' attitudes and perceptions of adults with intellectual disability

Background: Quality mental health care for adults with an intellectual disability (ID) depends upon the availability of appropriately trained and experienced psychiatrists. There have been few surveys of psychiatrists working with this population. Methods: This Australian study obtained psychiatrists' attitudes to and perceptions of the mental health needs of adults with an ID. Training needs were also sought. The survey instrument used was a purposely designed, 28-item self-administered questionnaire featuring multiple-choice and open-ended questions. Results: The majority of psychiatrists expressed concerns about treatment of this group, describing unmet needs. A total of 75% considered that antipsychotics were overused to control aggression, and 34% of psychiatrists were reluctant to treat adults with an ID. In total, 85% agreed that mental health in ID should be offered as a training option for psychiatric registrars, and that specialized mental health services would provide a high standard of care for this population. Conclusions: Broad concerns are raised regarding pathways to mental health care for adults with an ID in Australia. An Australia-wide training strategy needs to be developed. Partnerships between mental health, disability and community services that serve the mental health needs of this population, should actively seek to engage psychiatrists.

Analysis of the risk factors related to the immune humoral anti-Anaplasma marginale in dairy cattle

Anaplasma marginale is the most prevalent pathogen of cattle transmitted by ticks in the world. This study aimed to evaluate the risk factors for anaplasmosis in dairy cattle. Fifty dairy cattle from the herd of Empresa de Pesquisa Agropecuaria do Estado do Rio de Janeiro were selected by proportional stratified sampling. The risk factors evaluated were: physiological state, race pattern, number of lactations, milk production, infestation by Rhipicephalus microplus and animal density. Antibody activity against A. marginale was determined using the indirect enzyme-linked immunosorbent assay. The percentual values of seroprevalence for A. marginale were submitted to X2 test, and the level of minimum significance, to keep a factor in the model of logistic regression, was fixated in 5%. It was observed that pregnancy and lactation influenced significantly (p<0.05) in the seropositivity of the animals. Bos indicus animals had 5.21 times more chances of being seropositive than B. taurus animals. Primiparous female had 88% more chances of being seropositive than pluriparous female. Animals with high milk production were 63% more positive than low production animals. When infested by ticks the animals had 39% more chance of being seropositive to A. marginale. Bos indicus animals presented 5.21 times more chance of being seropositive than B. taurus animals. Primiparous females presented 88% more chance of being seropositive than the pluriparous ones. High milk production animals were 63% more positive than the low production ones. When infested by ticks the animals had 39% more chance of being seropositive to A. marginale. High density grazing provided for the animals 3.2 times more chances of being seropositive than low density ones. The herd was classified as erratic to A. marginale, even being placed in a steady enzootic area.

The TIM translocase in T. brucei contains Rhomboid-like proteins that are essential for mitochondrial protein import

The parasitic protozoon Trypanosoma brucei is one of the earliest branching eukaryotes that have mitochondria capable of oxidative phosphorylation. Their protein import systems are of similar complexity yet different composition than those in other eukaryotes. To elucidate the composition of the trypanosomal translocase of the inner mitochondrial membrane (TIM) we performed CoIPs of epitope-tagged TbTim17 and two other candidates in combination with SILAC-based quantitative mass spectrometry. This led to the identification of ten candidates for core TIM subunits. Eight of them were present in the previously determined inner membrane proteome and four show homology to small Tim chaperones. Three candidates, a trypanosomatid-specific 42 kDa protein (Tim42) and two putative orthologues of inactive rhomboid proteases were analyzed further. All three proteins are essential in both life cycle stages and their ablation results in a strong protein import defect in vivo and in vitro. Blue native PAGE revealed their presence in a high molecular weight complex. Unlike anticipated, trypanosomes have a highly complex TIM translocase that has extensively been redesigned. None of the three novel TIM subunits has ever been associated with mitochondrial protein import. Two of them belong to the rhomboid protease family, a member of which recently has been implicated in the ERAD translocation system. This suggests an exciting analogy between protein translocases of mitochondria and the ER.
