The Bivalent Fear of Evaluation Model proposes that the fears of positive and negative evaluation each uniquely contribute to social anxiety severity. However, the debate continues as to whether these are distinct constructs, and, if so, the degree of influence each has on social anxiety severity. This study used a longitudinal evaluation of these relationships in a clinical sample to identify whether the two fears differentially change over time and differentially relate to social anxiety severity.
Individuals with a social anxiety disorder (N = 105) completed measures of fears of negative and positive evaluation weekly, and social interaction anxiety monthly, for 12 weeks. Temporal relationships were assessed using residual dynamic structural equation modeling.
Fears of positive and negative evaluation both predicted the future status of the other (ϕ = 0.18, 95% credibility interval [0.10-0.28] and ϕ = 0.22 [0.12-0.35], respectively). Fear of negative evaluation (ϕ = 0.16 [0.05-0.28]) but not positiveuce social anxiety severity and minimize the indirect impact of fear of positive evaluation.
To determine if clinicopathologic (CP) factors could identify patients at "very low" and/or "very high" pretest probability of a high Oncotype DX (ODX) score.
A retrospective analysis of all patients that had ODX testing 2008-2018 at a single institution.
Of 215 patients, all 16 (7.4%) with "all high" risk CP factors had high ODX scores, and all 45 (20.9%) over age 50 with "all low" risk CP factors had ODX recommendations for no chemotherapy.
Oncotype DX results did not change chemotherapy recommendations in those with "very low" or "very high" pretest probability of high ODX scores.

Studies of nonmodel host species can illuminate how microbiota and their hosts interact in natural environments. We investigated the role of migratory behaviour in shaping the gut microbiota of free-ranging barn swallows (Hirundo rustica) by studying co-occurring migrant and resident subspecies sampled during the autumn migration at a migratory bottleneck. We found that within-host microbial richness (α-diversity) was similar between migrant and resident microbial communities. In SBI-477 research buy , we found that microbial communities (β-diversity) were significantly different between groups regarding both microbes present and their relative abundances. Compositional differences were found for 36 bacterial genera, with 27 exhibiting greater abundance in migrants and nine exhibiting greater abundance in residents. There was heightened abundance of Mycoplasma spp. and Corynebacterium spp. in migrants, a pattern shared by other studies of migratory species. Screens for key regional pathogens revealed that neither residents nor migrants carried avian influenza viruses and Newcastle disease virus, suggesting that the status of these diseases did not underlie observed differences in microbiome composition. Furthermore, the prevalence and abundance of Salmonella spp., as determined from microbiome data and cultural assays, were both low and similar across the groups. #link# Overall, our results indicate that microbial composition differs between migratory and resident barn swallows, even when they are conspecific and sympatrically occurring. Differences in host origins (breeding sites) may result in microbial community divergence, and varied behaviours throughout the annual cycle (e.g., migration) could further differentiate compositional structure as it relates to functional needs.
To examine the relationship between chronic external and internal head and neck lymphedema (HNL) and swallowing function in patients following head and neck cancer (HNC) treatment.
Seventy-nine participants, 1-3 years post treatment were assessed for external HNL using the MD Anderson Cancer Centre Lymphedema Rating Scale, and internal HNL using Patterson's Radiotherapy Edema Rating Scale. Swallowing was assessed via instrumental, clinical and patient-reported outcome measures.
HNL presented as internal only (68%), combined external/internal (29%), and external only (1%). Laryngeal penetration/aspiration was confirmed in 20%. Stepwise multivariable regression models, that accounted for primary site, revealed that a higher severity of external HNL and internal HNL was associated with more severe penetration/aspiration (P < .004 and P = .006, respectively), diet modification (P < .001 both), and poorer patient-reported outcomes (P = .037 and P = .014, respectively).
Increased swallowing issues can be expected in patients presenting with more severe external HNL and/or internal HNL following HNC treatment.

Anxiety is associated with aberrant patterns of cortical thickness in regions implicated in emotion regulation. However, few studies have examined cortical thickness differences between individuals with anxiety and healthy controls (HCs) across development, particularly during childhood when cortical thinning begins and anxiety risk increases. link2 A better understanding of age-related changes in cortical thickness patterns among anxious individuals is essential to develop plausible targets for early identification.
The current study examined how age impacted differences in cortical thickness patterns between HCs and anxious individuals. Participants included 233 individuals (ages 7-35) with a current anxiety disorder (n = 149) or no lifetime history of psychopathology (n = 84). Cortical thickness of regions that are implicated in emotion regulation (ventromedial prefrontal cortex [vmPFC], rostral anterior cingulate [rACC], and insula) were assessed.
All regions showed significant thinning with age, except led on developmental stage.Vibrio cholerae, the causative agent of cholera, is commonly isolated, along with other bacterial species, from chironomid insects (Diptera Chironomidae). Nevertheless, its prevalence in the chironomid egg masses' microbiota is less than 0.5%. V. cholerae secretes haemagglutinin/protease (HAP) that degrades the gelatinous matrix of chironomid egg masses and prevents hatching. Quorum sensing (QS) activates HAP production in response to accumulation of bacterial autoinducers (AIs). Our aim was to define the impact of chironomid microbiota on HAP production by V. cholerae. To study QS signaling, we used V. cholerae bioluminescence reporter strains (QS-proficient O1 El-Tor wild-type and QS-deficient mutants) and different bacterial species that we isolated from chironomid egg masses. These egg mass isolates, as well as a synthetic AI-2, caused an enhancement in lux expression by a V. cholerae QS-deficient mutant. The addition of the egg mass bacterial isolate supernatant to the QS-deficient mutant also enhanced HAP production and egg mass degradation activities. Moreover, the V. cholerae wild-type strain was able to proliferate using egg masses as their sole carbon source, while the QS-deficient was not. The results demonstrate that members of the chironomid bacterial consortium produce external chemical cues that, like AI-2, induce expression of the hapA gene in V. cholerae. link3 Understanding the interactions between V. cholerae and the insects' microbiota may help uncover the interactions between this pathogen and the human gut microbiota.
The aim of this study was to determine whether there has been a change in access to private dental services in regional and remote areas of Australia by comparing the distribution of private dental practices and dentists in 2011 to the distribution in 2018 according to state and territory and the Accessibility/Remoteness Index of Australia Plus.
A database of dental practices and dentists in Australia was compiled from open-access sources for 2011 and 2018; dental practices were mapped by state, Accessibility/Remoteness Index of Australia Plus and Statistical Area 2 census district and linked to population data.
Change in number of private dental practices, mean number of dentists per private practice, population per dental practice and mean number of dentists per population by geographic location from 2011 to 2018.
There were more dental practices in rural and remote areas in 2018 than in 2011. The percentage of Statistical Area 2s without a private dental practice was lower in 2018 but remained highre.Oxygenation reactions with molecular oxygen (O2 ) as the oxygen source provides a green and straightforward strategy for the construction of O-containing compounds. Demonstrated here is a novel N-heterocyclic carbene (NHC) catalyzed oxidative transformation of simple and readily available organic halides into valuable esters through the incorporation of O-atoms from O2 . Mechanistic studies prove that the deoxy Breslow intermediate generated in situ is oxidized to a Breslow intermediate for further transformation by this oxidative protocol. This method broadens the field of NHC catalysis and promotes oxygenation reactions with O2 .Coral cover is decreasing worldwide largely as a result of a rise in seawater temperatures that triggers coral bleaching and induces coral mortality. How coral reefs will respond to climate change will be a function of genetic variation and how it is partitioned within and among species. A critical initial step is to accurately delineate species and quantify their physiological potential to cope with heat stress. Cryptic species are morphologically similar but genetically distinct and may respond physiologically differently to climate change. A dominant Caribbean reef builder severely affected by climate change is the mountainous star coral, Orbicella faveolata. Recently in this journal, Dziedzic et al. reported quantitative genetic variation in the physiological response to thermal stress in a single population of this species, suggesting that variation within populations will allow these corals to adapt to rising ocean temperatures. We reanalysed their data and found multiple cryptic lineages rather than a single panmictic population, with one of the lineages being heat-intolerant. While different cryptic lineages co-occur in certain locations, there is at least one lineage that occurs only in a single location. Our finding of hidden lineages within a threatened species highlights the varying extinction risks faced by these independently evolving groups, especially when the prospects of survival under warmer oceans seem favourable for only some of them.In England, care to support people living at home is largely commissioned by local authorities (statutory organisations with responsibility for social care in specific localities) from non-statutory home-care providers (for-profit, not-for-profit, voluntary). This paper explores how managers of these services perceive commissioning arrangements and their impact on home-care providers, the care workforce and service users. Little formal research of providers' experiences of working with local authorities in a commissioning model is available. A qualitative study employed semi-structured telephone interviews with 20 managers of for-profit home-care providers from 10 selected local authority areas in England. Data were analysed using thematic analysis to identify main and subsidiary themes. Home-care providers reported operating in a complex and changeable partnership with commissioners, characterised by (a) relationships ranging from transactional to collaborative, (b) providers expressing a strong sense of public service motivation, (c) commissioning practices that were complex to negotiate, time-consuming and overly prescriptive, (d) frequent changes in commissioning practices and a perceived lack of strategic planning, which were reported as contributing to uncertainty and tension for providers and confusion for service users.
