Abstract
Digital health interventions can address governments' aims of providing better care, better outcomes, and lower costs. No previous research has examined attitudes toward digital sex therapy to understand what might facilitate, or hinder, the uptake of these interventions. This sequential mixed-methods study with qualitative structured interviews (n = 27) followed by a quantitative survey (n = 334) aimed to understand participants' expectations and attitudes toward digital sex therapy interventions. Participants reported a mixture of positive and negative attitudes to digital sex therapy. More positive attitudes, higher education level, and previous engagement in therapy predicted greater openness to using these interventions.

Abstract
There is a growing recognition that sexual problems can adversely impact health, well-being, and quality of life. Sex therapy provides individuals with an effective means of understanding, improving, and resolving their sexual difficulties. Yet, few individuals access a sex therapist when experiencing sexual difficulties and research on perceptions toward this service remains limited. The current study aimed to explore attitudes and beliefs held by a sample with a current or previous history of sexual problems toward sex therapy and therapists. A total of 27 individuals aged 19-53 participated in unmoderated structured interviews that were analyzed using reflexive thematic analysis. The results were organized into five categories, (1) overall perceptions of sex therapy, (2) when and for whom is sex therapy, (3) expectations, (4) beliefs about sex therapists, and (5) sources of beliefs. While the results indicated that participants held positive attitudes toward the service and about others seeking sex therapy, none had accessed sex therapy for their previous or current sexual problems. Numerous barriers relating to stigma, cost, and accessibility appeared to hinder the utilization of the service. The inaccurate and unrealistic beliefs about sex therapy and sex therapists highlight the need for increased education regarding the profession, which could reduce barriers and increase accessibility.

Abstract
Objective The Surviving Sepsis Campaign recommends systematic screening for sepsis. Although many sepsis screening tools include parent or healthcare professional concern, there remains a lack of evidence to support this practice. We aimed to test the diagnostic accuracy of parent and healthcare professional concern in relation to illness severity, to diagnose sepsis in children. Design This prospective multicenter study measured the level of concern for illness severity as perceived by the parent, treating nurse and doctor using a cross-sectional survey. The primary outcome was sepsis, defined as a pSOFA score >0. The unadjusted area under receiver-operating characteristic curves (AUC) and adjusted Odds Ratios (aOR) were calculated. Setting Two specialised pediatric Emergency Departments in Queensland. Patients Children aged 30 days to 18 years old that were evaluated for sepsis. Intervention None. Main Results 492 children were included in the study, of which 118 (23.9%) had sepsis. Parent concern was not associated with sepsis (AUC 0.53, 95% CI: 0.46-0.61, aOR: 1.18; 0.89-1.58) but was for PICU admission (OR: 1.88, 95% CI: 1.17-3.19) and bacterial infection (aOR: 1.47, 95% CI: 1.14-1.92). Healthcare professional concern was associated with sepsis in both unadjusted and adjusted models (nurses: AUC 0.57, 95% CI-0.50, 0.63, aOR: 1.29, 95% CI: 1.02-1.63; doctors: AUC 0.63, 95% CI: 0.55, 0.70, aOR: 1.61, 95% CI: 1.14-2.19). Conclusions While our study does not support the broad use of parent or healthcare professional concern in isolation as a pediatric sepsis screening tool, measures of concern may be valuable as an adjunct in combination with other clinical data to support sepsis recognition.

Abstract
INTRODUCTION Paediatric sepsis is a major contributor to morbidity and mortality worldwide. Assessing concern from parents and healthcare professionals to determine disease severity in a child evaluated for sepsis remains a field requiring further investigation. This study aims to determine the diagnostic accuracy of parental and healthcare professional concern in the diagnosis of children evaluated for sepsis. METHODS AND ANALYSIS This prospective multicentre observational study will be conducted over a 24-month period in the paediatric emergency department (ED) at two tertiary Australian hospitals. A cross-sectional survey design will be used to assess the level of concern in parents, nurses and doctors for children presenting to ED and undergoing assessment for sepsis. The primary outcome is a diagnosis of sepsis, defined as suspected infection plus organ dysfunction at time of survey completion. Secondary outcomes include suspected or proven infection and development of organ dysfunction, defined as a Paediatric Sequential Organ Failure Assessment Score >0, within 48 hours of presentation, paediatric intensive care unit admission, confirmed or probable bacterial infection independent of organ dysfunction, and hospital length of stay. ETHICS AND DISSEMINATION Ethics approval was obtained from Children's Health Queensland's Human Research Ethics Committee (HREC/17/QRCH/85). Findings will be shared with relevant stakeholders and disseminated via conferences and peer-reviewed journals TRIAL REGISTRATION NUMBER: WHO Universal Trial Number, U1111-1256-4537; ANZCTR number, ACTRN1262000134092.

Abstract
Whereas the majority of hot thyroid nodules are caused by somatic TSH-receptor mutations, the percentage of TSH-receptor mutation negative clonal hot nodules (HN) and thus the percentage of hot nodules likely caused by other somatic mutations are still debated. This is especially the case for toxic multinodular goiter (TMNG). 35 HNs [12 solitary hot nodules (SHN), 23 TMNG] were screened for somatic TSHR mutations in the exons 9 and 10 and for Gsα mutations in the exons 7 and 8 using DGGE. Determination of X-chromosome inactivation was used for clonality analysis. Overall TSHR mutations were detected in 14 out of 35 (40%) HNs. A nonrandom X-chromosome inactivation pattern was detected in 18 out of 25 (72%) HNs suggesting a clonal origin. Of 15 TSHR or Gsα mutation negative cases 13 (86.6%) showed nonrandom X-chromosome inactivation, indicating clonal origin. The frequency of activating TSHR and/or Gsα mutations was higher in SHNs (9 of 12) than in TMNGs (6 of 23). There was no significant difference for the incidence of clonality for HNs between TMNGs or SHNs (p: 0.6396). Activating TSHR and/or Gsα mutations were more frequent in SHNs than in TMNG. However, the frequency of clonality is similar for SHN and TMNG and there is no significant difference for the presence or absence of TSHR and/or Gsα mutations of clonal or polyclonal HNs. The high percentage of clonal mutation-negative HNs in SHN and TMNG suggests alternative molecular aberrations leading to the development of TSHR mutation negative nodules.

Abstract
The assessment of tumor vascularization by color flow Doppler sonography (CFDS) has been suggested for the distinction between benign and malignant thyroid nodules. Our objective was to investigate if the CFDS results reflect the percentage of histologically determined microvessels in adenomas (As), adenomatous nodules (ANs), and papillary carcinomas (PCs). Tissue sections from 10 adenomas, 8 ANs and 13 PC and surrounding tissue of 10 PCs and 2 benign nodules were immunostained for CD34. A computerized image analysis was used to determine the microvessel density in four hot spots and ten systematically selected fields. Preoperatively CFDS was performed and classified according to Frates et al. We found a consistent percentage increase of CD34 stained microvessels in PCs (83 and 96%) as compared to adenomas and ANs (38 and 49%) determined by the hot spot analysis and systematic field analysis. A ROC analysis on the basis of the histologically determined number of microvessels demonstrated 70% microvessels as an optimal cut point for the diagnosis of PC with the highest sensitivity of 92% and highest specificity of 89%. The analysis of the CFDS-classification IV for the distinction between PCs and adenomas and ANs showed a sensitivity of 62% with a specificity of 100%. The lower sensitivity of the CFDS classification as compared with the immunohistologic determination of the microvessel density indicates that the CFDS classification detects the pathognomonic intranodular microvessels only incompletely. The higher CFDS specificity is most likely due to the detection of other vascular aspects of malignancy in addition to intranodular microvessels.

Abstract
OBJECTIVE For thyroid tumors increased as well as decreased vessel densities have been reported. Because of different morphometric methods and specificities of previously used antibodies for small and large vessels our objective was to investigate and compare the density of large vessels and microvessels by different morphometric methods and antibodies in hot nodules(HN), cold nodules (CN), papillary carcinoma (PC) and Graves' disease (GD) to try to clarify some of these discrepancies. DESIGN Tissue sections from 29 HN, 22 CN, 19 PC and 8 GD thyroids were stained with the antibodies for CD34 and alpha-SMA. A computerized image analysis was used to calculate the mean area of endothelium (mEA) and the mean endothelium to tumor epithelial nucleus area ratio (mE/N) in four hot spots and ten systematically selected fields. MAIN OUTCOME We found a consistent increase of the CD34 stained percentage of microvessels in PC as compared to HN and CN determined by the hot spot analysis and systematic field analysis. This increased microvessel density in PC is of a similar magnitude as in GD, which is characterised by a prominent increase of vascularisation during its active disease stage. Our SMA staining results reveal a kind of mirror image of the CD34 staining results with higher vessel counts in the normal surrounding tissues as compared to HN, CN and PC. CONCLUSIONS The specific immunohistologic detection of microvessels with the CD34 antibody combined with their specific evaluation is able to clearly differentiate PCs from normal tissue, HN and CN.

Abstract
Retinoids are known to play important roles in organ development of the lung. Retinoids exert their activity by modulating the expression of numerous genes, generally influencing gene transcription, in target cells. In the present work, the mechanism by which retinoic acid (RA) regulates surfactant protein (SP) B expression was assessed in vitro. RA (9-cis-RA) enhanced SP-B mRNA in pulmonary adenocarcinoma cells (H441 cells) and increased transcriptional activity of the SP-B promoter in both H441 and mouse lung epithelial cells (MLE-15). Cotransfection of H441 cells with retinoid nuclear receptor (RAR)-alpha, -beta, and -gamma and retinoid X receptor (RXR)-gamma further increased the response of the SP-B promoter to RA. Treatment of H441 cells with RA increased immunostaining for the SP-B proprotein and increased the number of cells in which the SP-B proprotein was detected. An RA responsive element mediating RA stimulation of the human SP-B promoter was identified. RAR-alpha and -gamma and RXR-alpha but not RAR-beta or RXR-beta and -gamma were detected by immunohistochemical analysis of H441 cells. RA, by activating RAR activity, stimulated the transcription and synthesis of SP-B in pulmonary adenocarcinoma cells.

Abstract
Surfactant protein B (SP-B) is selectively expressed in bronchiolar and alveolar epithelial cells of the lung. We identified an upstream enhancer located in the 5'-flanking region of the human SP-B gene (-439 to -331 base pair, hSP-B(-439/-331)) by deletion analysis of SP-B-luciferase constructs assessed in transfection assays in vitro. The element cis-activated the expression of an SV40 promoter-luciferase reporter gene in a human pulmonary adenocarcinoma cell line (H441-4). Three distinct binding sites for the nuclear transcription protein, thyroid transcription factor 1 (TTF-1), were identified, and the purified TTF-1 homeodomain was bound to bhe region of hSP-B(-439/-331). Co-transfection of H441-4 cells with the expression vector pCMV-TTF-1 trans-activated the native human SP-B promoter and the SV40 promoter fused with the SP-B enhancer. Mutations of the TTF-1 binding sites in the upstream enhancer blocked TTF-1 binding and transactivation activity. In summary, TTF-1 interacts with distinct proximal (-80 to -110) and distal (-439 to -331) cis-acting elements than regulate lung epithelial cell-specific transcription of the human SP-B gene.

Abstract
We analyzed the expression of P-glycoprotein (Pgp) by immunohistochemistry using JSB-1 monoclonal antibody (MAb) on paraffin-embedded sections of the multi-drug resistant (MDR) (CHrC5 and CEM-VLB), and sensitive (AuxB1 and CEM) cell lines, and also in normal kidney, colon, adrenal and in kidney and colon carcinomas. After comparing the sensitivity of three different immunohistochemical techniques the peroxidase-antiperoxidase method was found to be the best. We then tested six different fixation methods. The MDR cell lines and human tissues demonstrated the strongest staining with B-5 fixative. Both MDR cell lines, but not the tissues fixed in 1% paraformaldehyde and Zamboni's fixative demonstrated weak staining. No immuno- reactivity could be detected in MDR cell lines and tissues fixed in 10% buffered or nonbuffered formalin or by the AMeX method of tissue processing. The present study clearly shows that the type of fixative is critical for the preservation of Pgp epitope recognized by JSB-1 MAb, and that B-5 fixative is expected to be equally applicable for the detection of Pgp in normal and neoplastic tissues.
