What skills do adolescents and young adults desire as they prepare for adult health care?

Background: The transition from pediatric to adult care is a period associated with adverse health outcomes (e.g., health care dropout, health deterioration and poor adherence to management) for adolescents and young adults (AYA) with chronic conditions and their caregivers.

Amplifying adolescent and emerging adult voices: Development of a pediatric-to-adult transition research advisory council.

Background: Adolescents and emerging adults (AEA) with chronic health conditions may face numerous challenges when undergoing the transition from pediatric to adult health care. Despite the need for engagement with AEA in health research, little is known about how researchers operationalize this engagement. In an effort to enhance transparency in the practices of patient engagement, this commentary details the process of developing a pediatric-adult transition-specific youth advisory council in Alberta: the Transition Research Advisory Council (TRAC).

The effect of the linker size in C-symmetrical chiral ligands on the self-assembly formation of luminescent triple-stranded di-metallic Eu(iii) helicates in solution.

Chiral lanthanide-based supramolecular structures have gained significant importance in view of their application in imaging, sensing and other functional purposes. We have designed chiral C2-symmetrical ligands (L) based on the use of two 2,6-pyridine-dicarboxylic-amide moieties (pda), that differ from one another by the nature of the diamine spacer groups (from 1,3-phenylenedimethanamine (1(S,S), 2(R,R)) and benzene-1,3-diamine (3(S,S), 4(R,R)) to much bulkier 4,4'-(cyclohexane-1,1-diyl)bis(2,6-dimethylaniline) (5(S,S), 6(R,R))) between these two pda units. The self-assembly between L and Eu(iii) ions were investigated in CH3CN solution at low concentration whereby the changes in the absorbance, fluorescence and Eu(iii)-centred emission spectra allowed us to model the binding equilibria occurring in the solution to the presence of [Eu:L2], [Eu2:L2], [Eu2:L3] assemblies and reveal their high binding constant values.

Assessing the accuracy of algorithm-derived cardiorespiratory fitness in surgical patients: a prospective cohort study.

Purpose: To determine if a non-exercise algorithm-derived assessment of cardiorespiratory fitness (CRF) accurately predicted estimated values obtained using a six-minute walk test (CRF) and the Duke Activity Status Index (CRF).

Methods: Following research ethics board approval, an observational cohort study was conducted in selected, consenting patients undergoing elective surgery. Participants completed questionnaires assessing their self-reported exercise capacity.

Executive dysfunction and presbycusis in older persons with and without memory loss and dementia.

Objective: To determine the relation of age-related auditory processing dysfunction and executive functioning.

Background: Central auditory dysfunction is common in Alzheimer dementia, but the mechanism is not established.

Method: A total of 313 volunteers from the Adult Changes in Thought surveillance cohort with adequate peripheral hearing were included in the study.

Self-assembly of hybrid organic-inorganic polyoxomolybdates: solid-state structures and investigation of formation and core rearrangements in solution.

We report here a facile synthetic and analytical approach that allows us to identify and characterize functionalized polyoxomolybdate clusters that form upon the partial reduction of Mo(VI) salts in the presence of organoarsonate ligands. We demonstrated that electrospray ionization mass spectrometry, in combination with X-ray crystallography, provides an extremely powerful tool, allowing us to exploit slight perturbations of the ligand structures for the preparation of a series of unprecedented cluster compounds. Redox-active transition metals that adopt cubane or related structures are of particular interest because of their resemblance to active sites of enzymes.

Photooxidation of guanine by a ruthenium dipyridophenazine complex intercalated in a double-stranded polynucleotide monitored directly by picosecond visible and infrared transient absorption spectroscopy.

Transient species formed by photoexcitation (400 nm) of [Ru(dppz)(tap)2]2+ (1) (dppz = dipyrido[3,2-a:2',3'-c]phenazine; tap=1,4,5,8-tetraazaphenanthrene) in aqueous solution and when intercalated into a double-stranded synthetic polynucleotide, [poly(dG-dC)]2, have been observed on a picosecond timescale by both visible transient absorption (allowing monitoring of the metal complex intermediates) and transient infrared (IR) absorption spectroscopy (allowing direct study of the DNA nucleobases). By contrast with its behavior when free in aqueous solution, excitation of 1 when bound to [poly(dG-dC)]2 causes a strong increase in absorbance at 515 nm due to formation of the reduced complex [Ru(dppz)(tap)2]+ (rate constant=(2.0+/-0.
