Pregnancies suspicious for triple I should be terminated. The confirmation of triple I is only possible by placental histology (histologically confirmed chorioamnionitis, HCA). Confirmation based on amniocentesis (positive Gram stain, low glucose concentration , positive culture) takes too long and is unreliable. Serial determinations of C‑reactive protein also do not allow reliable diagnosis of IAI. Studies using interleukin 6 measurements from the posterior fornix and/or cervical os are promising methods, the validation of which is awaited.We propose a novel method to exploit chirality of highly sensitive graphene plasmonic metasurfaces to characterize complex refractive indexes (RI) of viruses by detecting the polarization state of the reflected electric fields in the THz spectrum. A dispersive graphene metasurface is designed to produce chiral surface currents to couple linearly polarized incident fields to circularly polarized reflected fields. The metasurface sensing sensitivity is the result of surface plasmon currents that flow in a chiral fashion with strong intensity due to the underlying geometrical resonance. Consequently, unique polarization states are observed in the far-field with the ellipticity values that change rapidly with the analyte’s RI. The determination of bimolecular RI is treated as an inverse problem in which the polarization states of the virus is compared with a pre-calculated calibration model that is obtained by full-wave electromagnetic simulations. We demonstrate the polarization selective sensing method by RI discrimination of three different types of Avian Influenza (AI) viruses including H1N1, H5N2, and H9N2 is possible. Since the proposed virus characterization method only requires determination of the polarization ellipses including its orientation at monochromatic frequency, the required instrumentation is simpler compared to traditional spectroscopic methods which need a broadband frequency scan.The COVID-19 pandemic provides a rare opportunity to reveal the impact of reduced human activity on wildlife. I compared traffic volume and wildlife roadkill data along 18 km of highway before, during and after a 3-month period of COVID-19 restrictions with baseline data from the previous four years. Three marsupial herbivores comprised 89% of the 1820 roadkills recorded during the 4.5-year survey period rufous-bellied pademelon Thylogale billardierii (31.5% of total), common brushtail possum Trichosurus vulpecula (29.8%) and red-necked wallaby Notamacropus rufogriseus (27.9%). During April 2020, when human activity was most restricted in the study area, traffic volume decreased by 36% (i.e. by an average 13,520 vehicle movements per day) and wildlife roadkill decreased by 48% (i.e. from 44 to 23 roadkills). learn more However, when restrictions eased, traffic volume and wildlife roadkill returned to baseline levels indicating that the respite was brief in terms of animal welfare and of limited conservation value for these widespread and abundant species. Nevertheless, the results of this study suggest that even short periods of traffic reduction or road closures could be used as part of a management strategy for the conservation of endangered wildlife populations and re-wildling programs where roadkill is a risk factor.
COVID-19, a major ‘Public Health Emergencies of International Concern,’ had sought greater attention among researchers to study its pathogenesis, associated complications and management. However, there are only few studies that had studied its potential impact on mental health of general public, who are subjected to social distancing, community lockdown and restrictions in their routine activities.
The aim of this study is to assess the prevalence of psychological distress and mental health needs among general public in Tamil Nadu subjected to lockdown, social distancing amidst COVID-19 crisis. Tamil Nadu is one of the worst affected states of southern India.
A self-administered, web-based application study using ‘WHO-Self Reported Questionnaire-20’, in bilingual version, both English and Tamil, is used to screen the public for the level of distress. The study is done while the state is under extended lockdown and restricted movement.
A total of 918 respondents participated in the survey and it is fou it is prerogative to effectively manage fear, distress due to the COVID-19 and associated anxiety and depression among the public.
The new coronavirus disease 2019 (COVID-19) is a major health problem with a high rate of spread. We aimed to investigate herein the effects of the COVID-19 outbreak on depression and sexual dysfunction in patients with epilepsy.
One hundred and sixteen epilepsy patients admitted to our hospital from October-November 2019 were evaluated for sexual functions and depression using the Arizona Sexual Experiences Scale (ASEX) and Beck Depression Scale, respectively. These scales were re-applied in June 2020 and July 2020 to assess the impact of the outbreak on sexual function and depression in the same group of patients. The demographic and clinical characteristics of the patients were recorded and analyzed in SPSS.
During the pandemic period, the total Beck Depression Scale values increased significantly in the patients with epilepsy compared to the pre-pandemic period (p=0.048), and depressive symptoms showed an increasing trend (p=0.032). Although an increase in sexual dysfunction was also recorded, it was not statistically significant compared to the pre-pandemic period. In eight patients (6.9%), seizure frequency increased during the pandemic period. In the multivariate analysis, the only parameter that predicted the increase in seizure frequency was the number of drugs used. The Beck Depression Scale values were positively correlated with total male/female ASEX values, age, marital status, duration of illness, and seizure frequency.
The COVID-19 outbreak caused an increase in the tendency to depression in epilepsy patients and has also had a negative effect on sexual function. During public health outbreaks, clinicians should focus not only on seizure control in patients with epilepsy but also on their mental health.
