From 25 to 29 April 2020, the state of Indiana undertook testing of 3,658 randomly chosen state residents for the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, the agent causing COVID-19 disease. This was the first statewide randomized study of COVID-19 testing in the United States. Both PCR and serological tests were administered to all study participants. This paper describes statistical methods used to address nonresponse among various demographic groups and to adjust for testing errors to reduce bias in the estimates of the overall disease prevalence in Indiana. These adjustments were implemented through Bayesian methods, which incorporated all available information on disease prevalence and test performance, along with external data obtained from census of the Indiana statewide population. Both adjustments appeared to have significant impact on the unadjusted estimates, mainly due to upweighting data in study participants of non-White races and Hispanic ethnicity and anticipated false-positive and false-negative test results among both the PCR and antibody tests utilized in the study.

(CT) is routinely diagnosed by nucleic acid amplification tests (NAATs), which are unable to distinguish between nucleic acids from viable and non-viable CT organisms.

We applied our recently developed sensitive PCR (viability PCR) technique to measure viable bacterial CT load and explore associated determinants in 524 women attending Dutch sexual health centres (STI clinics), and who had genital or rectal CT.

We included women participating in the FemCure study (Netherlands, 2016-2017). At the enrolment visit (pre-treatment), 524 were NAAT positive (n=411 had genital and rectal CT, n=88 had genital CT only and n=25 had rectal CT only). We assessed viable rectal and viable genital load using V-PCR. We presented mean load (range 0 (non-viable) to 6.5 log

CT/mL) and explored potential associations with urogenital symptoms (coital lower abdominal pain, coital blood loss, intermenstrual bleeding, altered vaginal discharge, painful or frequent micturition), rectal symptoms (discharge, pain, blood loss), o497.

Patient-delivered partner therapy (PDPT) is a method for providing antibiotic treatment for the sexual partners of an index patient with an STI by means of a prescription or medication that the index patient gives to their sexual partner(s). Qualitative research regarding barriers and enablers to PDPT has largely focused on the views of healthcare providers. In this study, we sought to investigate the views of young people (as potential health consumers) regarding PDPT for chlamydia.

Semi-structured telephone interviews were conducted with young Australian men and women. Participants were asked to provide their views regarding PDPT from the perspective of both an index patient and partner. Purposive and snowball sampling was used. Data were analysed thematically.

We interviewed 22 people (13 women, 9 men) aged 18-30 years, 15 of whom had previously been tested for chlamydia. Despite none having previous knowledge of or experience using PDPT, all viewed it positively and thought it should be widely avails unlikely to fully replace partners' interactions with healthcare providers, it may facilitate partner notification conversations and provide partners greater choice on how, when and where they are treated.

This paper aims to estimate the percentage of European men who have sex with men (MSM) who may benefit from pre-exposure prophylaxis (PrEP), applying the three most widely used HIV risk indices for MSM (MSM Risk Index, Menza score, San Diego Early Test (SDET) score) and drawing on a large-scale multisite bio-behavioural survey (Sialon II).

The Sialon II study was a bio-behavioural survey among MSM implemented in 13 European cities using either time-location sampling or respondent-driven sampling. Biological and behavioural data from 4901 MSM were collected. Only behavioural data of HIV-negative individuals were considered. Three widely used risk indices to assess HIV acquisition risk among MSM were used to estimate individual HIV risk scores and PrEP eligibility criteria.

4219 HIV-negative MSM were considered. Regardless the HIV risk score used and the city, percentages of MSM eligible for PrEP were found to range between 5.19% and 73.84%. Overall, the MSM Risk Index and the Menza score yielded broadly w that a considerable percentage of MSM in each city should be offered PrEP in order to reduce HIV infections. As PrEP is highly effective at preventing HIV among MSM, our findings provide useful, practical guidance for stakeholders in implementing PrEP at city level to tackle HIV infections in Europe.

To review characteristics of individuals newly diagnosed with HIV following implementation of a national pre-exposure prophylaxis (PrEP) programme (comprehensive PrEP services, delivered in sexual health clinics) to inform future delivery and broader HIV prevention strategies.

We extracted data from national HIV databases (July 2015-June 2018). click here We compared sociodemographic characteristics of individuals diagnosed in the period before and after PrEP implementation, and determined the proportion of 'potentially preventable' infections with the sexual health clinic-based PrEP delivery model used.

Those diagnosed with HIV before PrEP implementation were more likely to be male (342/418, 81.8% vs 142/197, 72.1%, p=0.005), be white indigenous (327/418, 78.2% vs 126/197, 64.0%, p<0.001), report transmission route as sex between men (219/418, 52.4% vs 81/197, 41.1%, p=0.014), and have acquired HIV in the country of the programme (302/418, 72.2% vs 114/197, 57.9% p<0.001) and less likely to report transmisslivery and HIV combination prevention are required to widen access to individuals not benefiting from PrEP at present.

The sexual health clinic-based national PrEP delivery model appeared to best suit men who have sex with men and white indigenous individuals but had limited reach into other key vulnerable groups. Enhanced models of delivery and HIV combination prevention are required to widen access to individuals not benefiting from PrEP at present.

To develop comprehensive guidance that captures international impacts, causes and solutions related to emergency department (ED) crowding and access block.

Emergency physicians representing 15 countries from all International Federation of Emergency Medicine (IFEM) regions composed the Task Force. Monthly meetings were held via video-conferencing software to achieve consensus for report content. The report was submitted and approved by the IFEM Board on June 1, 2020.

A total of 14 topic dossiers, each relating to an aspect of ED crowding, were researched and completed collaboratively by members of the Task Force.

The IFEM report is a comprehensive document intended to be used in whole or by section to inform and address aspects of ED crowding and access block. Overall, ED crowding is a multifactorial issue requiring systems-wide solutions applied at local, regional, and national levels. Access block is the predominant contributor of ED crowding in most parts of the world.

Benefits may include improved teamwork, staff well-being and identification of learning opportunities. Existing literature indicates that while staff value HoD following significant events, it is infrequently undertaken in practice. Internationally, several frameworks for HoD have been developed, although none are widely adopted for use in the ED. A quality improvement project was conducted to introduce HoD into a single UK ED in North West England, between January and March 2019. Following stakeholder consultation, the 9-item 'TAKE STOCK' tool was developed. Implementation of the tool increased the number of HoD (0-2.2 HoD episodes/week). Findings from the first plan-do-study-act (PDSA) cycle are presented, which revealed the key strengths and limitations of this model. Staff perceptions of the tool were evaluated using a self-administered short questionnaire designed by the authors. Satisfaction with TAKE STOCK was assessed using 10-point numerical scales. Across respondents (n-15), average satisfaction scores exceeded 9 out of 10 concerning patient care, staff self-care, decision-making, education, teamwork and identification of equipment issues. Implementation of HoD into the ED is feasible and viewed as beneficial by staff. Implementation toolkits for TAKE STOCK have been requested by 42 additional UK hospitals and ambulance trusts, demonstrating significant interest in its use. Research is now required to formally validate HoD frameworks for use in the ED, and assess whether HoD results in sustained improvements to staff and patient outcomes.Eosinophils mediate pathological manifestations during tropical pulmonary eosinophilia (TPE), a potentially fatal complication of lymphatic filariasis, by mechanisms that are incompletely understood. Using two-dimensional gel electrophoresis, mass spectrometry, flow cytometry, and pharmacological and functional studies, we identified acidic calcium-independent phospholipase A2 (aiPLA2) as the master regulator of TPE pathogenesis. FACS-sorted lung eosinophils from TPE mice exhibited aiPLA2-dependent activation characterized by heavy calcium influx, F-actin polymerization, increased degranulation, and heightened reactive oxygen species generation. Interestingly, aiPLA2 also promoted alternative activation in lung macrophages and regulated the release of inflammatory intermediates from them. Treatment of TPE mice with MJ33, a nontoxic pharmacological inhibitor of aiPLA2, lowered eosinophil counts in the bronchoalveolar lavage fluid, reduced eosinophil peroxidase and β-hexosaminidase activity, increased airway width, improved lung endothelial barrier, and lowered the production of inflammatory lipid intermediates, which significantly improved the pathological condition of the lungs. Importantly, ex vivo reconstitution of arachidonic acid to eosinophils from MJ33-treated TPE mice increased eosinophil degranulation and inflammatory lipid intermediates underlining the pivotal role of aiPLA2 in arachidonic acid metabolism. Mechanistically, phosphorylation of JNK-1 regulated phospholipase activity of aiPLA2, whereas IgG cross-linking mediated pathological activation of eosinophils. Taken together, ours is the first study, to our knowledge, to report hitherto undocumented role of aiPLA2 in regulating TPE pathogenesis.HLA class I molecules that represent ligands for the inhibitory killer cell Ig-like receptor (KIR) 3DL1 found on NK cells are categorically defined as those HLA-A and HLA-B allotypes containing the Bw4 motif, yet KIR3DL1 demonstrates hierarchical recognition of these HLA-Bw4 ligands. To better understand the molecular basis underpinning differential KIR3DL1 recognition, the HLA-ABw4 family of allotypes were investigated. Transfected human 721.221 cells expressing HLA-A*3201 strongly inhibited primary human KIR3DL1+ NK cells, whereas HLA-A*2402 and HLA-A*2301 displayed intermediate potency and HLA-A*2501 failed to inhibit activation of KIR3DL1+ NK cells. Structural studies demonstrated that recognition of HLA-A*2402 by KIR3DL1 used identical contacts as the potent HLA-B*5701 ligand. Namely, the D1-D2 domains of KIR3DL1 were placed over the α1 helix and α2 helix of the HLA-A*2402 binding cleft, respectively, whereas the D0 domain contacted the side of the HLA-A*2402 molecule. Nevertheless, functional analyses showed KIR3DL1 recognition of HLA-A*2402 was more sensitive to substitutions within the α2 helix of HLA-A*2402, including residues Ile142 and Lys144 Furthermore, the presence of Thr149 in the α2 helix of HLA-A*2501 abrogated KIR3DL1+ NK inhibition.
