Dealing with anxiety:Relationships among interpersonal attachment style, psychological wellbeing and trait anxiety
Anxiety is a major contributor to poor quality mental health for many people in our community, and is a leading cause of presentations at medical and health clinics. Patterns of trait anxiety, or dysfunctional responding, have become ingrained in individualsâ approaches to problems they face. Research has shown that psychological wellbeing and interpersonal attachment style are both predictors of trait anxiety. However, the relationships among these variables have not been clarified. The current study sought to determine whether psychological wellbeing mediates the relationship between interpersonal attachment style and trait anxiety, and which of the six psychological wellbeing subscales would contribute most to any mediation effects. A convenience sample of 149 adult participants from South East Queensland, Australia completed a series of online questionnaires including a demographic questionnaire, the Trait Anxiety subscale of the State-Trait Anxiety Inventory (STAI-Form Y2), the Inventory of Parent and Peer Attachment (IPPA), Ryffâs Psychological Wellbeing Scale (PWB), and a Social Desirability Scale (SDS-17). Psychological Wellbeing was found to partially mediate the relationship between interpersonal attachment style and trait anxiety. The Positive Relations with Others subscale of the PWB was the only significant sub-scale of the PWB that significantly predicted trait anxiety. Overcoming anxiety appears to be most related in our sample to those who deal better with interpersonal relations. Targeting this aspect in treatment approaches appears most likely to lead to improved outcomes for clients.</jats:p
A measurement of Ï(Z â ΌΌ) using the LHCb detector at CERN
LHCb is one of four main experiments at the LHC in CERN. This thesis analyses 1.03 fbâ1 of âs = 7 TeV data collected in 2011. Measurements of the Z â ΌΌ cross-section and a differential measurement with respect to Z boson rapidity are presented. The primary motivations for making these measurements are to probe the accuracy of the Standard Model and constrain theoretical parton distribution functions. Final state radiation causes a downward shift in the reconstructed dimuon invariant mass and broadening in the peak. Reconstructing the radiated photon means the invariant mass distribution shift can be corrected for. Here final state radiation is implemented in LHCb simulation for the first time. It is used to study the effect on the reconstructed Z mass distribution. Selections are placed on the distance between the photon and muon, and the photon PT . The distribution is fitted to be 12% narrower than the non-reconstructed sample. The measured mass of the Z boson is increased from 91.047 GeV to 91.054 GeV. The kinematic requirements placed on the muons are: both muons must have transverse momentum, PT > 20 GeV; the dimuon invariant mass, 6
Sublethal effects of natural parasitism act through maternal, but not paternal; reproductive success in a wild population
Parasites are a major component of all animal populations. Males and females often differ in their levels of parasite prevalence, potentially leading to sex differences in the impact of parasitism on fitness, with important implications for the evolution of parasite and host traits including resistance, tolerance, and virulence. However, quantitative measures of the impact of parasitism under freeâliving conditions are extremely rare, as they require detailed host demographic data with measures of parasite burden over time. Here, we use endoscopy for direct quantification of naturalâparasite burdens and relate these to reproductive success over 7 yr in a wild population of seabirds. Contrary to predictions, only female burdens were associated with negative impacts of parasitism on breeding success, despite males having significantly higher burdens. Female reproductive success declined by 30% across the range of natural parasite burdens. These effects persisted when accounting for interannual population differences in breeding success. Our results provide quantitative estimates of profound subâlethal effects of parasitism on the population. Importantly, they highlight how parasites act unpredictably to shape ecological and evolutionary processes in different components of the same population, with implications for demography and selection on host and parasite traits
Antigenic and genetic characterization of a divergent African virus, Ikoma lyssavirus
In 2009, a novel lyssavirus (subsequently named Ikoma lyssavirus, IKOV) was detected in the brain of an African civet (Civettictis civetta) with clinical rabies in the Serengeti National Park of Tanzania. The degree of nucleotide divergence between the genome of IKOV and those of other lyssaviruses predicted antigenic distinction from, and lack of protection provided by, available rabies vaccines. In addition, the index case was considered likely to be an incidental spillover event, and therefore the true reservoir of IKOV remained to be identified. The advent of sensitive molecular techniques has led to a rapid increase in the discovery of novel viruses. Detecting viral sequence alone, however, only allows for prediction of phenotypic characteristics and not their measurement. In the present study we describe the in vitro and in vivo characterization of IKOV, demonstrating that it is (1) pathogenic by peripheral inoculation in an animal model, (2) antigenically distinct from current rabies vaccine strains and (3) poorly neutralized by sera from humans and animals immunized against rabies. In a laboratory mouse model, no protection was elicited by a licensed rabies vaccine. We also investigated the role of bats as reservoirs of IKOV. We found no evidence for infection among 483 individuals of at least 13 bat species sampled across sites in the Serengeti and Southern Kenya
Community pharmacist views on the early stages of implementation of a pathfinder sore throat test and treat service in Wales: an exploratory study
Objectives: To explore the views and opinions of community pharmacists regarding their initial experience of and levels of preparedness for the pathfinder sore throat test and treat (STTT) service in Wales.
Methods: A phenomenological qualitative approach with constructivist paradigm was adopted as the first cycle of ongoing action research. Semi-structured interviews with community pharmacists who had completed at least three consultations within the first 3 weeks of the service were conducted, with informed consent and audio recorded. Interviews were transcribed ad verbatim and data were thematically analysed both inductively and deductively.
Results: A total of seven interviews with pharmacists who had conducted more than three consultations identified three main themes: 1) perceived impact of the service on patient care, including the value of the structure and technology infrastructure, the role of STTT towards antimicrobial stewardship, and its potential role in rebalancing primary care resources so that workload is distributed appropriately among healthcare professionals; 2) factors that empower pharmacists to deliver the service, in particular quality and consistency of training, appropriate staffing resource and internally motivated willingness to engage; 3) interface with GP surgeries such as nature of existing relationships before implementing the service, role of GP staff and GP perceived value of STTT.
Conclusion: The pathfinder STTT service has been well received by pharmacists who recognised the serviceâs role in providing patient education and contributing to principles of antimicrobial stewardship and described factors that would empower them to deliver the service confidently. Results have been fed back to the service implementation team to inform future developments

Mechanisms of host manipulation by Neisseria gonorrhoeae
Neisseria gonorrhoeae (also known as gonococcus) has been causing gonorrhoea in humans since ancient Egyptian times. Today, global gonorrhoea infections are rising at an alarming rate, in concert with an increasing number of antimicrobial-resistant strains. The gonococcus has concurrently evolved several intricate mechanisms that promote pathogenesis by evading both host immunity and defeating common therapeutic interventions. Central to these adaptations is the ability of the gonococcus to manipulate various host microenvironments upon infection. For example, the gonococcus can survive within neutrophils through direct regulation of both the oxidative burst response and maturation of the phagosome; a concerning trait given the important role neutrophils have in defending against invading pathogens. Hence, a detailed understanding of how N. gonorrhoeae exploits the human host to establish and maintain infection is crucial for combating this pathogen. This review summarizes the mechanisms behind host manipulation, with a central focus on the exploitation of host epithelial cell signaling to promote colonization and invasion of the epithelial lining, the modulation of the host immune response to evade both innate and adaptive defenses, and the manipulation of host cell death pathways to both assist colonization and combat antimicrobial activities of innate immune cells. Collectively, these pathways act in concert to enable N. gonorrhoeae to colonize and invade a wide array of host tissues, both establishing and disseminating gonococcal infection

In Vitro and In Silico Analysis of New n-Butyl and Isobutyl Quinoxaline-7-carboxylate 1,4-di-N-oxide Derivatives against Trypanosoma cruzi as Trypanothione Reductase Inhibitors
American trypanosomiasis is a worldwide health problem that requires attention due to ineffective treatment options. We evaluated n-butyl and isobutyl quinoxaline-7-carboxylate 1,4-di-N-oxide derivatives against trypomastigotes of the Trypanosoma cruzi strains NINOA and INC-5. An in silico analysis of the interactions of 1,4-di-N-oxide on the active site of trypanothione reductase (TR) and an enzyme inhibition study was carried out. The n-butyl series compound identified as T-150 had the best trypanocidal activity against T. cruzi trypomastigotes, with a 13% TR inhibition at 44 ΌM. The derivative T-147 behaved as a mixed inhibitor with Ki and Ki' inhibition constants of 11.4 and 60.8 ”M, respectively. This finding is comparable to the TR inhibitor mepacrine (Ki = 19 ”M)
The oral health of secondary school pupils:baseline data from the Brushing RemInder 4 Good oral HealTh (BRIGHT) trial
Background This paper describes the sociodemographics and oral health of UK secondary school pupils. They were participants of the BRIGHT trial, which was designed to evaluate the effectiveness of a toothbrushing intervention to reduce dental caries. Methods Overall, 4,680 pupils aged 11-13 years attending 42 secondary schools in England, Scotland and Wales with above average proportion of pupils eligible for free school meals, were recruited to the trial. Sociodemographic data were collected. Participants had a clinical assessment for caries, plaque and bleeding and completed measures of oral and general health-related quality of life and oral health behaviours (frequency of toothbrushing, dental attendance and cariogenic food/drinks consumed). Regression analyses were performed. Results Over one-third (34.7%) of participants had caries experience, with 44.5% reporting their oral health had an impact on their daily lives. Factors associated with a statistically significant increased likelihood of caries experience were older age, being female, eligibility for free school meals, worse oral health-related quality of life, higher cariogenic diet, less than twice-daily toothbrushing, living in a more deprived area and lower school attendance. Conclusions The prevalence and impact of dental caries on the lives of pupils remains high, with further oral health promotion activities needed in targeted secondary schools.</p
