Quarterly analysis of Mental Capacity Act 2005, Deprivation of Liberty Safeguards Assessments (England) Quarters 1 to 3 2009/10

Hospitals and care homes are making use of new measures designed to protect people unable to give consent for their care.The Mental Capacity Act Deprivation of Liberty Safeguards were introduced by law on 1 April 2009 to provide a legal framework for depriving someone of their liberty where they are unable to give informed consent regarding their care. The statistics presented here provide the first official information about authorisations to legally detain a person using the legislation.The safeguards apply to people aged 18 and above who suffer from a mental disorder of the mind (such as dementia or a profound learning disability) and who lack capacity to give consent to the arrangements made for their care and / or treatment. The safeguards cover people in all hospitals and care homes in the statutory, independent and voluntary sectors.A rigorous, standardised assessment and authorisation process is used to ensure only appropriate use is made of the safeguards.Key facts?The number of authorisation requests were: 1,772 in quarter 1 1,681 in quarter 2 and, 1,869 in quarter 3. ?Of the total assessments completed in each quarter, a higher proportion were for females than for males ?For each quarter, around three out of four assessments were made by local authorities while the remaining ones were made by primary care trusts. ?The percentage of authorisations granted leading to someone being deprived of their liberty varied between 33.5 per cent and 50.7 per cent across quarters 1 to 3. ?At 31 December 2009 1,074 people were subject to such authorisations.Quarterly analysis of Mental Capacity Act 2005, Deprivation of Liberty Safeguards Assessments (England) Quarter 1 (0.31MB)Quarterly analysis of Mental Capacity Act 2005, Deprivation of Liberty Safeguards Assessments (England) Quarter 2 (0.31MB)Quarterly analysis of Mental Capacity Act 2005, Deprivation of Liberty Safeguards Assessments (England) Quarter 3 (0.31MB)Have your say - give us your comments on this publication��

Synthesis And Antiproliferative Activity Of 8-hydroxyquinoline Derivatives Containing A 1,2,3-triazole Moiety.

Twelve novel 8-hydroxyquinoline derivatives were synthesized with good yields by performing copper-catalyzed Huisgen 1,3-dipolar cycloaddition (click reaction) between an 8-O-alkylated-quinoline containing a terminal alkyne and various aromatic or protected sugar azides. These compounds were evaluated in vitro for their antiproliferative activity on various cancer cell types. Protected sugar derivative 16 was the most active compound in the series, exhibiting potent antiproliferative activity and high selectivity toward ovarian cancer cells (OVCAR-03, GI50 < 0.25 μg mL(-1)); this derivative was more active than the reference drug doxorubicin (OVCAR-03, GI50 = 0.43 μg mL(-1)). In structure-activity relationship (SAR) studies, the physico-chemical parameters of the compounds were evaluated and docking calculations were performed for the α-glucosidase active site to predict the possible mechanism of action of this series of compounds.

Characterization studies of 1-(4-cyano-2-oxo-1,2-dihydro-1-pyridyl)-3-(4-cyano-1,2-dihydro-1-pyridyl)propane formed from the reaction of hydroxide Ion with 1,3-Bis-(4-cyano pyridinium)propane

The aqueous alkaline reaction of 1,3-bis(4-cyanopyridinium)propane dibromide, a reactant constituted of two pyridinium rings linked by a three-methylene bridge, generates a novel compound,1 -(4-cyano-2-oxo-1,2-dihydro-1-pyridyl)-3-(4-cyano-1,2-dihydro-1-pyridyl)propane. The reaction pathway is attributed to the proximity of the OH- ion inserted between two pyridinium moieties, which occurs only in bis(pyridinium) derivatives connected by short methylene spacers, where charge-conformational effects are important.

Effect of CO2 and 1-octen-3-ol attractants for estimating species richness and the abundance of diurnal mosquitoes in the southeastern Atlantic forest, Brazil

Studies have shown that both carbon dioxide (CO2) and octenol (1-octen-3-ol) are effective attractants for mosquitoes. The objective of the present study was to evaluate the attractiveness of 1-octen-3-ol and CO2 for diurnal mosquitoes in the southeastern Atlantic forest. A Latin square experimental design was employed with four treatments: CDC-light trap (CDC-LT), CDC-LT and 1-octen-3-ol, CDC-LT and CO2 and CDC-LT with 1-octen-3-ol and CO2. Results demonstrated that both CDC-CO2 and CDC-CO2-1-octen-3-ol captured a greater number of mosquito species and specimens compared to CDC-1-octen-3-ol; CDC-LT was used as the control. Interestingly, Anopheles (Kerteszia) sp. was generally attracted to 1-octen-3-ol, whereas Aedes serratus was the most abundant species in all Latin square collections. This species was recently shown to be competent to transmit the yellow fever virus and may therefore play a role as a disease vector in rural areas of Brazil.
