BACKGROUND Syphilis is a sexually transmitted infection (STI) transmitted from person to person mainly by sexual intercourse or through vertical transmission during pregnancy. Female sex workers (FSWs) are exposed especially to syphilis infection, and besides all the efforts to control the spread of STIs, syphilis prevalence is still rising, mainly occurring in low-income countries. This study aimed to investigate the syphilis prevalence, demographic characteristics and sexual habits among FSWs in the Amazon region of Brazil. METHODS A cross-sectional study was carried out including 184 FSWs from 3 countryside cities of the state of Pará, Amazon region of Brazil. A venereal disease research laboratory test and an indirect immunoenzyme assay to test antibodies against Treponema pallidum were used for screening syphilis infection, while sexual habits and demographic data information were collected through a semi-structured questionnaire. Data was analyzed comparing groups with/without syphilis. Selleckchem ABT-888 Poisson regressio control syphilis spread, which is a rising problem in Brazil and in other several countries.After publication of the original article [1], we were notified that an author’s family name has been erroneously spelled.

Ozone producing low-pressure Hg vapor lamps emit mainly 254 nm ultraviolet light C (UVC) with about 10% power of Vacuum-ultraviolet (VUV) light at 185 nm. The combination of UVC and VUV can inactivate airborne pathogens by disrupting the genetic materials or generation of reactive oxygen species, respectively. In this study, inactivation of common bacteria including Escherichia coli ATCC25922 (E. coli), Extended Spectrum Beta-Lactamase-producing E. coli (ESBL), Methicillin-resistant Staphylococcus aureus (MRSA) and Mycobacterium tuberculosis (MTB), and that of influenza A viruses H1N1 and H3N2 under the radiation from ozone producing low-pressure Hg vapor lamps was examined. Log reduction values at different treatment durations were determined. METHODS In vitro tests were carried out. Various bacterium and virus suspensions were added onto nitrocellulose filter papers and subjer bacteria, 4-log10 inactivation for viruses and 5-log10 inactivation for MTB, most of the bacteria required ≤10 min of VUV treatment, 20 min for the influenza viruses while MTB needed about 30 min VUV treatment. This indicated that VUV light is an effective approach against different environmental microorganisms.BACKGROUND Chronic liver disease (CLD) is an important cause of morbidity and mortality and can lead to hepatic fibrosis. This study was conducted to evaluate the diagnostic value of real-time shear wave elastography (SWE) in the assessment of hepatic fibrosis. METHODS A systematic search of databases was performed for publications on SWE during the period between 2010 and 2017. The identified studies were analyzed using Meta-disc 1.4 software to integrate and analyze the data. RESULTS Eleven studies comprising 1560 patients were included for analysis. The pooled sensitivity, specificity and diagnostic odds ratio were 0.85 (95% CI 0.82-0.87), 0.79 (95% CI 0.76-0.82) and 30.81 (95% CI 16.55-57.34), respectively for patients with a Metavir-score of ≥ F2; 0.87 (95% CI 0.84-0.91), 0.84 (95% CI 0.82-0.87), 41.45 (95% CI18.25-94.45), respectively for patients with ≥ F3; 0.88(95% CI 0.83-0.91), 0.91 (95% CI 0.89-0.92), 67.18 (95% CI30.02-150.31), respectively for patients with ≥ F4. The areas under the receiver operating characteristic curve of the three groups were 0.9147, 0.9223 and 0.9520, respectively. CONCLUSIONS Our work demonstrates that SWE is highly accurate for detecting and staging hepatic fibrosis.BACKGROUND Acute flaccid myelitis (AFM) are reported to be associated with enterovirus D68 infection. Though an increasing number of AFM cases were reported with EV-D68 infection in the US, few such cases have been found in China. CASE PRESENTATION A 6-year-old boy presented with acute flaccid myelitis (AFM) involving left arm after fever and respiratory symptoms for 6 days. Computed Tomography (CT) revealed inflammation in both lungs and magnetic resonance imaging (MRI) of the brain and spine showed swelling in the left frontal lobe and brain stem. The patient was diagnosed with meningomyelitis. EV-D68 was detected from pharyngeal samples 36 days after the onset of the disease. CONCLUSION We report the first EV-D68 infection in case of AFM in mainland China. AFM surveillance systems is recommended to be established in China to guide diagnosis, case reporting, and specimen collection and testing for better understanding its etiologies.BACKGROUND Timely diagnosis of dementia has a wide range of benefits including reduced hospital emergency department presentations, admissions and inpatient length of stay, and improved quality of life for patients and their carers by facilitating access to treatments that reduce symptoms, and allow time to plan for the future. Memory clinics can provide such services, however there is no ‘gold standard’ model of care. This study involved the co-creation of a model of care for a new multidisciplinary memory clinic with local community members, General Practitioners (GPs), policy-makers, community aged care workers, and service providers. METHODS Data collection comprised semi-structured interviews (N = 98) with 20 GPs, and three 2-h community forums involving 53 seniors and community/local government representatives, and 25 community healthcare workers. Interviews and community forums were audio-recorded, transcribed verbatim, and coded by thematic analysis using Quirkos. RESULTS GPs’ attitudes towards their sign models of care for people with dementia that take into account the local communities’ needs. Findings pave the way for the development of a potential new “gold standard” memory clinic model of care and operationalise new national clinical guidelines.BACKGROUND Stratified care involves subgrouping patients based on key characteristics, e.g. prognostic risk, and matching these subgroups to appropriate early treatment options. The STarT MSK feasibility and pilot cluster randomised controlled trial (RCT) examined the feasibility of a future main trial and of delivering prognostic stratified primary care for patients with musculoskeletal pain. The pilot RCT was conducted in 8 UK general practices (4 stratified care; 4 usual care) with 524 patients. GPs in stratified care practices were asked to use i) the Keele STarT MSK development tool for risk-stratification and ii) matched treatment options for patients at low-, medium- and high-risk of persistent pain. This paper reports on a nested qualitative study exploring the feasibility of delivering stratified care ahead of the main trial. METHODS ‘Stimulated-recall’ interviews were conducted with patients and GPs in the stratified care arm (n = 10 patients; 10 GPs), prompted by consultation recordings. Data were analysed thematically and mapped onto the COM-B behaviour change model; exploring the Capability, Opportunity and Motivation GPs and patients had to engage with stratified care.
