Maternal syphilis infection in pregnancy is associated with specific adverse pregnancy outcomes, even after adjusting for potential confounders. These data can be used to counsel patients with syphilis in pregnancy, and in developing approaches to clinical care. Due to the increased risk of stillbirth, perhaps such patients should receive antenatal testing. Further research is necessary to investigate the mechanisms of morbidity.

The assessment of language in patients post-comatose patients is limited by their reduced behavioral repertoire. We developed the Brief Evaluation of Receptive Aphasia (BERA) tool for assessing phonological, semantic and morphosyntactic abilities in patients with severe brain injury based on visual fixation responses.

Prospective cross-sectional study and case reports.

The BERA and Language Screening Test were first administered to 52 conscious patients with aphasia on two consecutive days in order to determine the validity and reliability of the BERA. Four post-comatose patients were further examined with the BERA, the Coma Recovery Scale-Revised (CRS-R), positron emission tomography and structural magnetic resonance imaging.

The BERA showed satisfactory intra- and inter-rater reliability, as well as internal and concurrent validity in patients with aphasia. The BERA scores indicated selective receptive difficulties for phonological, semantic and particularly morphosyntactic abilities in post-comatose patients. These results were in line with the cortical distribution of brain lesions.

The BERA may complement the widely used CRS-R for assessing and diagnosing patients with disorders of consciousness by providing a systematic and detailed characterization of residual language abilities.

They play crucial roles in initiating innate and adaptive immune responses. TLR7/8 activation protects the host against invading pathogens and enhances immune responses. In contrast, sustained TLR7/8 signaling leads to immune overreaction. Therefore, agonists or antagonists targeting TLR7/8 signaling are favorable drug candidates for the treatment of immune disorders.Areas covered Basic knowledge about TLR7 and TLR8 and their signaling pathways are briefly reviewed. Various therapeutic agents have been designed to activate or antagonize TLR7/8 signaling pathways, and their safety and efficacy for the treatment of multiple diseases have been investigated in preclinical animal models and clinical trials. TLR7/8 agonists exhibit potent antiviral activity and regulate anti-tumor immune responses. TLR7 agonists have also been used as adjuvants to improve vaccine immunogenicity and generate greater seroprotection. TLR7/8 antagonists are promising candidates for the treatment of autoimmune and inflammatory diseases.Expert opinion TLR7/8 pathways are favorable targets for immunological therapies. Future research should concentrate on the optimization of drug safety, efficiency, and specificity. Detailed mechanistic studies will contribute to the development of TLR7/8 immunomodulators and novel therapeutic strategies.

Preeclampsia increases the risk of cardiovascular mortality and morbidity both during pregnancy and long term after the labor by causing cardiac changes that may lead to atrial and ventricular arrhythmias.

We aimed to investigate noninvasive predictors of atrial and ventricular arrhythmias and cardiac structural changes in preeclampsia.

The study included 34 preeclampsia patients as the study group and 33 healthy pregnant women as the control group. The presence of fragmented QRS morphology, P dispersion, QT dispersion, Tp-e/QTc ratio, inter- and intra-atrial electromechanical delay, left ventricular mass index was evaluated in the groups by 12 lead- ECG and standard and tissue Doppler echocardiography.

Left ventricular mass index and relative wall thickness, and E/Em ratio was significantly higher in preeclampsia. Inter- and intra-atrial electromechanical delay and Tp-e were prolonged, and P dispersion, QT dispersion, and Tp-e/QTc ratio were increased significantly in patients with preeclampsia. In addition, fragmented QRS morphology was seen in 76.5% of patients with preeclampsia while it was present in only 27.3% of the control group (

 < .001).

Preeclampsia causes significant cardiac structural and electrocardiographic alterations that may increase the risk of atrial and/or ventricular arrhythmias. A more thorough and earlier cardiac assessment and closer follow-up of these patients would be useful to avoid further complications.

Treatment of saline wastewater requires efficient, cost-effective, rapid, and green technologies, so as to mitigate the negative impacts of salinity on agricultural land. Green technology of phytodesalination is proposed to reduce salinity in the wastewater using salt tolerant plant species. present study was designed with an aim to investigate the sodium (Na+) removal capacity of salt tolerant and high biomass producing macrophytes on synthetic saline wastewater. Sesuvium portulacastrum (sea purslane), Pluchea indica (Indian camphorweed), Typha angustifolia (narrow leaf cattail) and Heliconiapsittacorum (heliconia) were collected, cultivated in the greenhouse, subsequently treated with 0 (control) and 217 mM NaCl (salt stress) for 4 weeks. Overall growth performance, physiological changensities and Na-removal rate in relation to swamp habitat.Novelty statementT. angustifolia and H. psittacorum have high plant biomass, they showed higher Na+ removal efficiency at 4.4% and 5.7%, respectively; whereas due to lower plant biomass, S. portulacastrum and P. indica resulted in removal of only 0.6 and 0.8% Na+ from the batch. Based on the information from this investigation, the selected candidate plant species can further be studied in the constructed wetland together with the controlled environments including optimized flowrate, vertical or horizontal flow system, plant densities and Na-removal rate in relation to swamp habitat.Two new alkaloids, phranisines A-B (1-2), along with two known compounds, N-p-Coumaroyl serotonin (3) and N-p-coumaroyl-tryptamine (4), were isolated from the roots of Phragmites australis. The structures of 1-4 were established on the basis of extensive spectroscopic. The absolute configuration of compounds 1-2 were identified through quantum-chemical electronic circular dichroism (ECD) calculation compared with their experimental CD. All the isolated compounds were tested for their cytotoxic activities against HeLa and MCF-7 human cancer cell lines, and compounds 2-4 showed moderate cytotoxic activities against HeLa cell lines with IC50 values ranging from 13.2 to 18.6 μM.Water, sanitation and hygiene (WASH) factors are responsible for 11.4% of deaths in Zambia, making WASH a key public health concern. Despite annual waterborne disease outbreaks in the nation's peri-urban (slum) settlements being linked to poor WASH, few studies have proactively analysed and conceptualised peri-urban WASH and its maintaining factors. Our study aimed to (a) establish residents' definition of peri-urban WASH and their WASH priorities; and (b) use ecological theory to analyse the peri-urban WASH ecosystem, highlighting maintaining factors. Our study incorporated 16 young people (aged 17-24) residing in peri-urban Lusaka, Zambia in a photovoice exercise. Participants took photographs answering the framing question, 'What is WASH in your community?' Then, through contextualisation and basic codifying, participants told the stories of their photographs and made posters to summarise problems and WASH priorities. Participant contextualisation and codifying further underwent theoretical thematic analysis to pinpoint causal factors alongside key players, dissecting the peri-urban WASH ecosystem via the five-tier ecological theory ranging from intrapersonal to public policy levels. Via ecological theory, peri-urban WASH was defined as (a) poor practice (intrapersonal, interpersonal); (b) a health hazard (community norm); (c) substandard and unregulated (public policy, organisational); and (d) offering hope for change (intrapersonal, interpersonal). Linked to these themes, participant findings revealed a community level gap, with public policy level standards, regulations and implementation having minimal impact on overall peri-urban WASH and public health due to shallow community engagement and poor acknowledgement of the WASH realities of high-density locations. Rather than a top-down approach, participants recommended increased government-resident collaboration, offering residents more ownership and empowerment for intervention, implementation and defending of preferred peri-urban WASH standards.A new lignan derivative, 11-deoxykompasinol A (1), together with six known compounds, including five lignan glycosides (2-6) and a jasmonic acid derivative (7), were isolated from the seeds of Orychophragmus violaceus. Structure of the new compound was elucidated on the basis of extensive spectroscopic techniques and ECD (electronic circular dichroism calculations). Since most komasinol derivatives were isolated as racemate, the absolute configuration of this type of compound was reported for the first time. The known compounds were identified by comparison with data reported in the literature. All compounds were tested for their cytotoxic activities against the Hela and HepG2 cell lines in vitro. The new compound 1 exhibited obvious cytotoxicity against the two cell lines with IC50 values of 9.43 and 18.26 μM, respectively. Compounds 2, 5, and 7 were found to possess moderate cytotoxicity against the above cell lines.This systematic review was aimed at identifying the psychometric properties of field-based tests for assessing physical fitness in soccer referees. Electronic databases were searched up to May 2020 for studies that informed about the reliability and/or validity of at least one field-based physical fitness test for soccer referees. A total of 13 studies analysed the psychometric properties of the field-based physical fitness tests proposed by the Fédération Internationale de Football Association (FIFA) (aerobic endurance, n = 8; anaerobic endurance, n = 3; and speed, n = 8), while seven investigations focused on field-based physical fitness tests specifically designed for assessing aerobic endurance (n = 1) or change of direction (COD) (n = 6). According to the observed reliability and validity values, the Assistant Referee Intermittent Endurance test (ARIET), the 50-m sprint test and the Modified Agility test (MAT) seem, respectively, the best available options for assessing aerobic endurance, speed, and COD in soccer referees.
