Things You Do: A randomized controlled trial of an unguided ultra-brief intervention to reduce symptoms of depression and anxiety.

The 'Things You Do' encompass five types of actions that are strongly associated with good mental health: Healthy Thinking, Meaningful Activities, Goals and Plans, Healthy Habits, and Social Connections. Ultra-brief interventions which increase how often people perform these actions may decrease depression and anxiety. A two-arm randomized controlled trial (N = 349) compared an unguided ultra-brief intervention based on the 'Things You Do' against a waitlist control.

A pilot study examining whether restricting and resuming specific actions systematically changes symptoms of depression and anxiety. A series of N-of-1 trials.

Anxiety and depressive disorders are highly prevalent and a leading cause of disability. Understanding how symptoms develop could lead to new preventive and clinical interventions. This pilot study examined whether systematically restricting specific behaviours (target actions) associated with good psychological health would increase psychological symptoms in healthy participants, and whether resuming those actions would reduce symptoms to baseline levels.

Optic neuritis with potential for poor outcome.

The Optic Neuritis Treatment Trial previously reported that corticosteroids accelerated visual recovery in optic neuritis (ON) without improving outcome. This finding related largely to multiple sclerosis (MS), and subsequently neurologists tended to await spontaneous recovery in ON. Since then, non-MS cases of ON have been identified with antibodies to aquaporin-4 (AQP4) or myelin oligodendrocyte glycoprotein (MOG).

Bedaquiline as Treatment for Disseminated Nontuberculous Mycobacteria Infection in 2 Patients Co-Infected with HIV.

Nontuberculous mycobacteria can cause disseminated infections in immunocompromised patients and are challenging to treat because of antimicrobial resistance and adverse effects of prolonged multidrug treatment. We report successful treatment with bedaquiline, a novel antimycobacterial drug, as part of combination therapy for 2 patients with disseminated nontuberculous mycobacteria co-infected with HIV.

Prolonged Scar-in-a-Jar: an in vitro screening tool for anti-fibrotic therapies using biomarkers of extracellular matrix synthesis.

Background: Idiopathic pulmonary fibrosis (IPF) is a rapidly progressing disease with challenging management. To find novel effective therapies, better preclinical models are needed for the screening of anti-fibrotic compounds. Activated fibroblasts drive fibrogenesis and are the main cells responsible for the accumulation of extracellular matrix (ECM).

ABIN-1 heterozygosity sensitizes to innate immune response in both RIPK1-dependent and RIPK1-independent manner.

ABIN-1 (encoded by the gene Tnip1) is a ubiquitin-binding protein that can interact with ubiquitin-editing enzyme A20 (encoded by the gene TNFAIP3) to restrain the activation of necroptosis and NF-κB activation. Genetic variants in the genes Tnip1 and TNFAIP3 are both strongly associated with susceptibility to autoimmune chronic inflammatory diseases such as psoriasis vulgaris and systemic lupus erythematosus (SLE) in humans. Here we investigated the mechanism by which ABIN-1 regulated innate immune responses.

Regulation of a distinct activated RIPK1 intermediate bridging complex I and complex II in TNFα-mediated apoptosis.

Stimulation of cells with TNFα can promote distinct cell death pathways, including RIPK1-independent apoptosis, necroptosis, and RIPK1-dependent apoptosis (RDA)-the latter of which we still know little about. Here we show that RDA involves the rapid formation of a distinct detergent-insoluble, highly ubiquitinated, and activated RIPK1 pool, termed "iuRIPK1." iuRIPK1 forms after RIPK1 activation in TNF-receptor-associated complex I, and before cytosolic complex II formation and caspase activation.

Case report: a diagnostically challenging conjunctival mass caused by the Epstein-Barr virus.

We present a paediatric case of infectious mononucleosis in a 13-year old, manifesting with follicular conjunctivitis and a conjunctival mass in one eye with no evidence of leucocytosis on the blood count. The diagnosis was confirmed following surgical excision and biopsy. The case represented a diagnostic challenge due to its atypism and given the steady increase in the prevalence of EBV-related ocular diseases in the last years, this report can serve as an example to prompt earlier serological tests to identify the aetiology in similar cases.

Systemic reactions and anaphylaxis with an acute serum tryptase ≥14 μg/L: retrospective characterisation of aetiology, severity and adherence to National Institute of Health and Care Excellence (NICE) guidelines for serial tryptase measurements and specialist referral.

Aims: To characterise patients with systemic reactions and anaphylaxis with an acute serum tryptase of ≥14 μg/L against recently published World Allergy Organisation (WAO) diagnostic criteria. To also perform a clinical audit to assess adherence to National Institute of Health and Care Excellence (NICE) guideline recommendations regarding serial tryptase measurements and specialist referral.

Methods: A systematic retrospective survey (2006-2010) was carried out (n=171; males=86; mean age±SD 48±20 years) and data were extracted from emergency department and specialist allergy clinic records.

Discovery of a rapidly metabolized, long-acting β(2) adrenergic receptor agonist with a short onset time incorporating a sulfone group suitable for once-daily dosing.

A series of novel, potent, and selective human β2 adrenoceptor agonists incorporating a sulfone moiety on the terminal right-hand-side phenyl ring of (R)-salmeterol is presented. Sulfone 10b had salmeterol-like potency and selectivity profile, long duration of action on guinea pig trachea, and longer than salmeterol duration of action in vivo, suitable for once-daily dosing. It had lower than salmeterol oral absorption in rat, lower bioavailability in rat and dog, and a high turnover in human hepatocytes.

Characterization of selective Calcium-Release Activated Calcium channel blockers in mast cells and T-cells from human, rat, mouse and guinea-pig preparations.

Loss of function mutations in the two key proteins which constitute Calcium-Release Activated Calcium (CRAC) channels demonstrate the critical role of this ion channel in immune cell function. The aim of this study was to demonstrate that inhibition of immune cell activation could be achieved with highly selective inhibitors of CRAC channels in vitro using cell preparations from human, rat, mouse and guinea-pig. Two selective small molecule blockers of CRAC channels; GSK-5498A and GSK-7975A were tested to demonstrate their ability to inhibit mediator release from mast cells, and pro-inflammatory cytokine release from T-cells in a variety of species.

Pharmacological characterization of GSK573719 (umeclidinium): a novel, long-acting, inhaled antagonist of the muscarinic cholinergic receptors for treatment of pulmonary diseases.

Activation of muscarinic subtype 3 (M3) muscarinic cholinergic receptors (mAChRs) increases airway tone, whereas its blockade improves lung function and quality of life in patients with pulmonary diseases. The present study evaluated the pharmacological properties of a novel mAChR antagonist, GSK573719 (4-[hydroxy(diphenyl)methyl]-1-{2-[(phenylmethyl)oxy]ethyl}-1-azoniabicyclo[2.2.

Recurrent third nerve palsy as the presenting feature of neurofibromatosis 2.

Neurofibromatosis 2 (NF2) is a rare autosomal dominant disorder associated with the development of multiple central and peripheral nervous system tumors. Patients with NF2 are often diagnosed in adulthood, with symptoms of an isolated tumor or hearing loss associated with vestibular schwannomas. Diagnosing NF2 in children is complicated by the fact that the diagnostic criteria often are not met at presentation and there is usually no family history of the disease.

In vitro pharmacological characterization of vilanterol, a novel long-acting β2-adrenoceptor agonist with 24-hour duration of action.

Vilanterol trifenatate (vilanterol) is a novel, long-acting β(2)-adrenoceptor (β(2)-AR) agonist with 24 h activity. In this study, we describe the preclinical pharmacological profile of vilanterol using radioligand binding and cAMP studies in recombinant assays as well as human and guinea pig tissue systems to characterize β(2)-AR binding and functional properties. Vilanterol displayed a subnanomolar affinity for the β(2)-AR that was comparable with that of salmeterol but higher than olodaterol, formoterol, and indacaterol.

The discovery of long-acting saligenin β₂ adrenergic receptor agonists incorporating a urea group.

A series of novel, potent and selective human β(2) adrenoceptor agonists incorporating a urea moiety on the terminal right-hand side phenyl ring of (R)-salmeterol is presented. Urea 9j had long duration of action in vitro on guinea pig trachea, and also in vivo similar to that of salmeterol. It had lower oral absorption and bioavailability than salmeterol in both rat and dog.

Developmental evaluation: building innovations in complex environments.

Developmental evaluation is an emerging approach to program evaluation that emphasizes innovation and learning. It is particularly well suited to evaluating innovative programs in their earliest stages of development and adapting existing programs to complex or changing environments. Key features of the developmental evaluation approach include a tight integration between evaluators and program staff and the use of data for continuous program improvement.

The discovery of long-acting saligenin β₂ adrenergic receptor agonists incorporating hydantoin or uracil rings.

A series of novel, potent and selective human β(2) adrenoceptor agonists incorporating a hydantoin or a uracil ring on the right-hand side phenyl ring of (R)-salmeterol is presented. Hydantoin 12a had long duration of action in vitro on guinea pig trachea, and 12h in guinea pigs in vivo at its EC(90) 25 μM. It had lower oral absorption than salmeterol in rats, and lower bioavailability than salmeterol in vivo in both rats and dogs (2% and 5%, respectively).

Synthesis and structure-activity relationships of long-acting beta2 adrenergic receptor agonists incorporating metabolic inactivation: an antedrug approach.

A series of saligenin beta(2) adrenoceptor agonist antedrugs having high clearance were prepared by reacting a protected saligenin oxazolidinone with protected hydroxyethoxyalkoxyalkyl bromides, followed by removal of the hydroxy-protecting group, alkylation, and final deprotection. The compounds were screened for beta(2), beta(1), and beta(3) agonist activity in CHO cells. The onset and duration of action in vitro of selected compounds were assessed on isolated superfused guinea pig trachea.

Synthesis and structure-activity relationships of long-acting beta2 adrenergic receptor agonists incorporating arylsulfonamide groups.

A series of saligenin alkoxyalkylphenylsulfonamide beta(2) adrenoceptor agonists were prepared by reacting a protected saligenin oxazolidinone with alkynyloxyalkyl bromides, followed by Sonogashira reaction, hydrogenation, and deprotection. The meta-substituted primary sulfonamide was more potent than the para- and the ortho-analogues. Primary sulfonamides were more potent than the secondary and tertiary analogues.

Oxazolidinones as novel human CCR8 antagonists.

High-throughput screening of the corporate compound collection led to the discovery of a novel series of N-substituted-5-aryl-oxazolidinones as potent human CCR8 antagonists. The synthesis, structure-activity relationships, and optimization of the series that led to the identification of SB-649701 (1a), are described.

Advanced restorative techniques.

Many alternative techniques are available to ensure the best possible outcome for an implant restoration.

Discovery of 4-[3-(trans-3-dimethylaminocyclobutyl)-1H-indol-5-ylmethyl]-(4S)-oxazolidin-2-one (4991W93), a 5HT(1B/1D) receptor partial agonist and a potent inhibitor of electrically induced plasma extravasation.

Utilizing a pharmacophoric model of binding of 3-(2-aminoethyl)indoles to 5HT(1B/1D) receptors, we identified the 3-aminocyclobutyl group as a potential ethylamine isostere. A novel multidimensional chemometric approach was used to predict the intrinsic activity (degree of agonism) at the receptor. A qualitative model for pharmacokinetic properties was then used to guide the synthesis toward molecules likely to have oral bioavailability in humans.
