Molecular antimicrobial resistance surveillance for neisseria gonorrhoeae, Northern Territory, Australia
Neisseria gonorrhoeae antimicrobial resistance (AMR) is a globally recognized health threat; new strategies are needed to enhance AMR surveillance. The Northern Territory of Australia is unique in that 2 different first-line therapies, based primarily on geographic location, are used for gonorrhea treatment. We tested 1,629 N. gonorrhoeae nucleic acid amplification testâpositive clinical samples, collected from regions where ceftriaxone plus azithromycin or amoxicillin plus azithromycin are recommended first-line treatments, by using 8 N. gonorrhoeae AMR PCR assays. We compared results with those from routine culture-based surveillance data. PCR data confirmed an absence of ceftriaxone resistance and a low level of azithromycin resistance (0.2%), and that penicillin resistance was \u3c5% in amoxicillin plus azithromycin regions. Rates of ciprofloxacin resistance and penicillinase-producing N. gonorrhoeae were lower when molecular methods were used. Molecular methods to detect N. gonorrhoeae AMR can increase the evidence base for treatment guidelines, particularly in settings where culture-based surveillance is limited

The effects of distraction on metacognition and metacognition on distraction: evidence from recognition memory
The effects of auditory distraction in memory tasks have been examined to date with procedures that minimize participantsâ control over their own memory processes. Surprisingly little attention has been paid to metacognitive control factors which might affect memory performance. In this study, we investigate the effects of auditory distraction on metacognitive control of memory, examining the effects of auditory distraction in recognition tasks utilizing the metacognitive framework of Koriat and Goldsmith (1996), to determine whether strategic regulation of memory accuracy is impacted by auditory distraction. Results replicated previous findings in showing that auditory distraction impairs memory performance in tasks minimizing participantsâ metacognitive control (forced-report test). However, the results revealed also that when metacognitive control is allowed (free-report tests), auditory distraction impacts upon a range of metacognitive indices. In the present study, auditory distraction undermined accuracy of metacognitive monitoring (resolution), reduced confidence in responses provided and, correspondingly, increased participantsâ propensity to withhold responses in free-report recognition. Crucially, changes in metacognitive processes were related to impairment in free-report recognition performance, as the use of the âdonât knowâ option under distraction led to a reduction in the number of correct responses volunteered in free-report tests. Overall, the present results show how auditory distraction exerts its influence on memory performance via both memory and metamemory processes
Bottom Reflectance in Ocean Color Satellite Remote Sensing for Coral Reef Environments
Most ocean color algorithms are designed for optically deep waters, where the seafloor has little or no effect on remote sensing reflectance. This can lead to inaccurate retrievals of inherent optical properties (IOPs) in optically shallow water environments. Here, we investigate in situ hyperspectral bottom reflectance signatures and their separability for coral reef waters, when observed at the spectral resolutions of MODIS and SeaWiFS sensors. We use radiative transfer modeling to calculate the effects of bottom reflectance on the remote sensing reflectance signal, and assess detectability and discrimination of common coral reef bottom classes by clustering modeled remote sensing reflectance signals. We assess 8280 scenarios, including four IOPs, 23 depths and 45 bottom classes at MODIS and SeaWiFS bands. Our results show: (i) no significant contamination (Rrscorr 17 m for MODIS and >19 m for SeaWiFS for the brightest spectral reflectance substrate (light sand) in clear reef waters; and (ii) bottom cover classes can be combined into two distinct groups, âlightâ and âdarkâ, based on the modeled surface reflectance signals. This study establishes that it is possible to efficiently improve parameterization of bottom reflectance and water-column IOP retrievals in shallow water ocean color models for coral reef environments

The Use of Unusual Psychological Theories in Psychobiography: A Case Study and Discussion
This chapter argues for the use of âunusualâ theories in psychobiographical research through the presentation of a case study using such a theory. Historically, psychobiographical research has predominantly made use of the work of psychoanalytic and psychodynamic theorists and developmental theorists, while more recent psychobiographical approaches have preferred more modern, empirically based. However, over reliance on a few theories within psychobiographical research creates the possibility for narrow explanations of complex lives. Given the proliferation of theoretical modes in psychology the current use of theory barely scratches the surface of available explanatory paradigms. This chapter argues for the value of casting the explanatory net wider, and for the inclusion of more psychological theories in psychobiographical work.
Using a psychobiographical case study, the chapter illustrates how a âforgottenâ psychological theory (script theory, based on the work of Tomkins) can serve as an extremely useful explanatory paradigm for a complex religious figure. The case study focuses on Gordon Hinckley (b. 1910, d. 2008), the fifteenth president of The Church of Jesus Christ of Latter-Day Saints (commonly referred to as the Mormon Church), who remains a prominent figure in contemporary Mormonism and played a key role in the rapid growth and increasingly positive public profile of the Religion throughout the twentieth and twenty-first centuries. Using Tomkinsâ script theory in conjunction with a psychobiographical method and the analysis of data gathered from published speeches, this study explores Hinckleyâs personality structure and identifies three core psychological scripts
Non-infectious illness after tick bite
Tick bites are common and may have non-infectious complications. Reactions range from local reactions to systemic syndromes, tick paralysis, mammalian meat allergy and tick anaphylaxis. Management revolves around prevention with vector avoidance and immediate removal of the tick if bitten. Treatment of bite reactions is usually symptomatic only with anti-histamines or corticosteroids. Adrenaline may be indicated for severe cases
Spiramicin
Concentrating on the treatment of infectious diseases, the content is divided into 4 sections: antibiotics, anti-fungal drugs,anti-parasitic drugs and anti-viral drugs, and is highly structured for ease of reference.Within each section, each chapter is structured to cover susceptibility, formulations and dosing (adult and paediatric), pharmacokinetics and pharmacodynamics, toxicity and drug distribution, detailed discussion regarding clinical uses, a feature unique to this title
The role of immunomodulation in the management of infections of the CNS
Interactions between the immune and nervous systems are involved in many disease processes. Modulation of inflammation can provide an important opportunity to enhance regeneration within the central nervous system. This authoritative book defines the key cellular players in mounting an inflammatory response and highlights critical factors in the target organ that influence the nature of that response and its capacity either to damage or protect the brain.
