Unhomely

As winter’s dusk encroaches on The Rocks, under the shadowy reach of the Sydney Harbour Bridge, anonymous and unnoticed by the lively crowds, the shutters open, and the blank upper windows flash alive in vacant Reynold’s Cottage. Through the unraveling night the cottage innards twist and flutter, spit and ooze with glimpses of disarray, despair and turmoil, the windows spirit-lenses on the turbulent world of mid-twentieth century Sydney

Pyridazinediones and amino acid receptors: theoretical studies, design, synthesis, and evaluation of novel analogues

http://www.pharmacol.usyd.edu.au/thesis This thesis is primarily concerned with a class of chemical compounds known as pyridazinediones, being 6-membered aromatic rings containing two adjacent nitrogen atoms (pyridazine), doubly substituted with oxygen. In particular, the work focuses on pyridazine-3,6-diones, derivatives of maleic hydrazide (1). Understanding of the chemistry of these compounds is extended, using theoretical and synthetic techniques. This thesis is also concerned with two very important classes of receptors which bind amino acids in the brain: firstly, the inhibitory GABA receptor, which binds g-aminobutyric acid (GABA) (2) in vivo, and for which muscimol (3) is an agonist of the GABAA subclass; secondly, Excitatory Amino Acid (EAA) receptors, which bind glutamate (4) in vivo, and in particular the AMPA subclass, for which (S)-2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionic acid (AMPA) (5) is an agonist. The connection between pyridazinediones and amino acid receptors is the design, synthesis, and evaluation of structures based on pyridazinediones as potential GABA and EAA receptor ligands. Techniques of theoretical chemistry, molecular modelling, synthetic chemistry, and in vitro pharmacology are used to explore pyridazine-3,6-dione derivatives as ligands

No Treatment versus 24 or 60 Weeks of Antiretroviral Treatment during Primary HIV Infection: The Randomized Primo-SHM Trial

Background: The objective of this study was to assess the benefit of temporary combination antiretroviral therapy (cART) during primary HIV infection (PHI). Methods and Findings: Adult patients with laboratory evidence of PHI were recruited in 13 HIV treatment centers in the Netherlands and randomly assigned to receive no treatment or 24 or 60 wk of cART (allocation in a 1:1:1 ratio); if therapy was clinically indicated, participants were randomized over the two treatment arms (allocation in a 1:1 ratio). Primary end points were (1) viral set point, defined as the plasma viral load 36 wk after randomization in the no treatment arm and 36 wk after tr Conclusions: In this trial, temporary cART during PHI was found to transiently lower the viral set point and defer the restart of cART during chronic HIV infection

Liever inleiden dan afwachten bij aterme zwangerschapshypertensie en milde preeclampsie: HYPITAT-studie

OBJECTIVE: To investigate what would benefit women with mild full-term pregnancy-related hypertension most: induction of labour or expectant monitoring, from the perspective of clinical effectiveness, maternal quality of life, and costs. DESIGN: Randomised clinical trial. Trial registration number ISRCTN08132825. METHODS: We undertook a multicentre randomised controlled trial in 38 hospitals in the Netherlands between October 2005 and March 2008. We enrolled patients with a singleton pregnancy in cephalic presentation at 36-41 weeks' gestation, who had gestational hypertension or mild preeclampsia. Participants were randomly allocated to receive either induction of labour or expectant monitoring. The primary outcome was a composite measure of poor maternal outcome, defined as maternal mortality, maternal morbidity (eclampsia, 'haemolysis, elevated liver enzymes, low platelets' (HELLP) syndrome, pulmonary oedema, thrombo-embolic disease and abruptio placentae), progression to severe hypertension or proteinuria, and major postpartum haemorrhage. Secondary outcomes were mode of delivery, neonatal outcome, maternal quality of life and costs. Analysis was by intention to treat. RESULTS: A total of 756 patients were allocated to receive induction of labour (n = 377 patients) or expectant monitoring (n = 379). No cases of maternal or neonatal death or eclampsia were recorded. Development of poor maternal outcome was significantly lower in the induction of labour group (117 women) than the expectant monitoring group (166 women) (31% versus 44%; relative risk 0.71 (95% CI: 0.59-0.86); p < 0.001). The caesarean section rate was lower among women in the induction of labour group (n = 54) compared to women in the expectant monitoring group (n = 72) (14% versus 19%; relative risk 0.75 (95% CI: 0.55-1.04)< p = 0.085). Neonatal outcomes and quality of life were comparable between both groups. Induction of labour is a cost saving strategy (difference euro 831). CONCLUSION: For women with full-term gestational hypertension and pre-eclampsia, induction of labour is associated with improved maternal outcome and lower costs, without the additional risk of a caesarean section being necessary

Gravitational Lensing at Millimeter Wavelengths

With today's millimeter and submillimeter instruments observers use gravitational lensing mostly as a tool to boost the sensitivity when observing distant objects. This is evident through the dominance of gravitationally lensed objects among those detected in CO rotational lines at z>1. It is also evident in the use of lensing magnification by galaxy clusters in order to reach faint submm/mm continuum sources. There are, however, a few cases where millimeter lines have been directly involved in understanding lensing configurations. Future mm/submm instruments, such as the ALMA interferometer, will have both the sensitivity and the angular resolution to allow detailed observations of gravitational lenses. The almost constant sensitivity to dust emission over the redshift range z=1-10 means that the likelihood for strong lensing of dust continuum sources is much higher than for optically selected sources. A large number of new strong lenses are therefore likely to be discovered with ALMA, allowing a direct assessment of cosmological parameters through lens statistics. Combined with an angular resolution <0.1", ALMA will also be efficient for probing the gravitational potential of galaxy clusters, where we will be able to study both the sources and the lenses themselves, free of obscuration and extinction corrections, derive rotation curves for the lenses, their orientation and, thus, greatly constrain lens models.Comment: 69 pages, Review on quasar lensing.

Non-AIDS defining cancers in the D:A:D Study-time trends and predictors of survival : a cohort study

BACKGROUND:Non-AIDS defining cancers (NADC) are an important cause of morbidity and mortality in HIV-positive individuals. Using data from a large international cohort of HIV-positive individuals, we described the incidence of NADC from 2004-2010, and described subsequent mortality and predictors of these.METHODS:Individuals were followed from 1st January 2004/enrolment in study, until the earliest of a new NADC, 1st February 2010, death or six months after the patient's last visit. Incidence rates were estimated for each year of follow-up, overall and stratified by gender, age and mode of HIV acquisition. Cumulative risk of mortality following NADC diagnosis was summarised using Kaplan-Meier methods, with follow-up for these analyses from the date of NADC diagnosis until the patient's death, 1st February 2010 or 6 months after the patient's last visit. Factors associated with mortality following NADC diagnosis were identified using multivariable Cox proportional hazards regression.RESULTS:Over 176,775 person-years (PY), 880 (2.1%) patients developed a new NADC (incidence: 4.98/1000PY [95% confidence interval 4.65, 5.31]). Over a third of these patients (327, 37.2%) had died by 1st February 2010. Time trends for lung cancer, anal cancer and Hodgkin's lymphoma were broadly consistent. Kaplan-Meier cumulative mortality estimates at 1, 3 and 5 years after NADC diagnosis were 28.2% [95% CI 25.1-31.2], 42.0% [38.2-45.8] and 47.3% [42.4-52.2], respectively. Significant predictors of poorer survival after diagnosis of NADC were lung cancer (compared to other cancer types), male gender, non-white ethnicity, and smoking status. Later year of diagnosis and higher CD4 count at NADC diagnosis were associated with improved survival. The incidence of NADC remained stable over the period 2004-2010 in this large observational cohort.CONCLUSIONS:The prognosis after diagnosis of NADC, in particular lung cancer and disseminated cancer, is poor but has improved somewhat over time. Modifiable risk factors, such as smoking and low CD4 counts, were associated with mortality following a diagnosis of NADC
