Extranodal natural killer T cell lymphoma of the oropharyx: case report
Authors: Abou-Halawa Ashraf Saad , Ibrahim Ibrahim Hassan , Eid Mahmoud Hassan , Ahmed Mohamed Rifaat 
Published: August 2021

AbstractBackgroundT cell lymphoma of the upper aerodigestive tract is a rare entity usually presenting as midfacial ulcerative lesion. It is extremely rare to present as non-healing erosive lesion of the oropharynx.Case presentationA 29-year-old female patient presented with odynophagia and trismus for several months. An “inflammatory” oropharyngeal ulcer was diagnosed and she was treated with repeated courses of antibiotics and corticosteroids without response. Recently, she had some blood stained saliva and vomited fresh blood. When seen, she had extensive painful ulcer eroding the right side of the soft palate and right tonsillar area. The ulcer had a whitish floor and ragged border without any tendency to heal. A second biopsy was taken and proved the lesion to be extranodal natural killer T cell lymphoma (ENKTL). The patient was treated with a modified SMILE (steroid, methotrexate, ifosfamide,l-asparaginase, and etoposide) protocol.ConclusionsExtranodal natural killer T cell lymphoma can manifest first in the oropharynx. If left untreated it may lead to deep erosive lesion and major oral bleeding. SMILE chemotherapy protocol was used in our patient with good early response.
H/D Isotope Effects in Keto-Enol Tautomerism of β-Dicarbonyl Compounds —Importance of Nuclear Quantum Effects of Hydrogen Nuclei—

Abstract
Deuterium isotope effects in the keto-enol tautomerism of β-dicarbonyl compounds (malonaldehyde, acetylacetone, dibenzoylmethane, and avobenzone) have been studied using a B3LYP+D functional level of multi-component density functional theory (MC_DFT), which can directly take nuclear quantum effects (NQEs) of the hydrogen nuclei into account. We clearly show that the keto-enol energy difference becomes smaller by deuterium substitution, which is in reasonable agreement with the corresponding experimental evidence. Our MC_DFT study also reveals the hydrogen/deuterium (H/D) isotope effect in geometries and shows that the deuterium substitution weakens the intramolecular hydrogen-bonded interaction in the enol form. Direct treatment of NQEs of hydrogen nuclei via the MC_DFT method is essential for analyzing the H/D isotope effect in keto-enol tautomerism of β-dicarbonyl compounds. Such isotope effects cannot be reproduced in the conventional DFT scheme with harmonic zero-point vibrational corrections.
Perceptions of ethical dilemmas in Australian paramedicine
Authors: Shearer Kirsty , Thomas Matthew , Signal Tania 
Published: August 2021

Background: Paramedics experience a range of ethical dilemmas in the course of their work. To date, ethical dilemmas by Australian paramedics have not been documented. With the scope of practice becoming increasingly complex, paramedic education may not have evolved to meet holistic professional demands. Aim: To describe the ethical dilemmas experienced by contemporary Australian paramedics. Methods: An online survey, based on a previous instrument, was used to explore a range of ethical dilemmas. Findings: Paramedics face a range of ethical dilemmas in their everyday practice. While several demographic variables were associated with different perceptions, the results of this study highlight that a paramedic's years of experience is most consistently associated with their perception of ethical dilemmas. Conclusion: Australian paramedics experience a range of ethical dilemmas consistent with previous international findings. Years of experience in the profession features heavily and is relied upon more so than education, suggesting that educational approaches to ethics education in paramedicine need to be reconsidered.
Current management of trimalleolar ankle fractures

Published: August 2021

A trimalleolar ankle fracture is considered unstable and treatment is generally performed operatively. Computed tomography is important for the operative planning by providing an elaborated view of the posterior malleolus. Trimalleolar ankle fractures have a rising incidence in the last decade with up to 40 per 100,000 people per year. With a growing number of elderly patients, trimalleolar ankle injuries will become more relevant in the form of fragility fractures, posing a particular challenge for trauma surgeons. In patients with osteoporotic trimalleolar ankle fractures and relevant concomitant conditions, further evidence is awaited to specify indications for open reduction and internal fixation or primary transfixation of the ankle joint. In younger, more demanding patients, arthroscopic-assisted surgery might improve the outcome, but future research is required to identify patients who will benefit from assisted surgical care. This review considers current scientific findings regarding all three malleoli to understand the complexity of trimalleolar ankle injuries and provide the reader with an overview of treatment strategies and research, as well as future perspectives.

Published: August 2021

Multicore fibers are expected to be a game-changer in the coming decades thanks to their intrinsic properties, allowing a larger transmission bandwidth and a lower footprint in optical communications. In addition, multicore fibers have recently been explored for quantum communication, attesting to their uniqueness in transporting high-dimensional quantum states. However, investigations and experiments reported in literature have been carried out in research laboratories, typically making use of short fiber links in controlled environments. Thus, the possibility of using long-distance multicore fibers for quantum applications is still to be proven. We characterize here for the first time, to the best of our knowledge, in terms of phase stability, multiple strands of a four-core multicore fiber installed underground in the city of L’Aquila, with an overall fiber length up to about 25 km. In this preliminary study, we investigate the possibility of using such an infrastructure to implement quantum-enhanced schemes, such as high-dimensional quantum key distribution, quantum-based environmental sensors, and more, in general, quantum communication protocols.

Published: August 2021

In the diagnosis of severe contagious diseases such as Ebola, severe acute respiratory syndrome, and COVID-19, there is an urgent need for protein sensors with large refractive index sensitivities. Current terahertz metamaterials cannot be used to develop such protein sensors due to their low refractive index sensitivities. A simple method is proposed that is compatible with all geometrical structures of terahertz metamaterials to increase their refractive index sensitivities. This method uses patterned photoresist to float the split-ring resonators (SRRs) of a terahertz metamaterial at a height of 30 μm from its substrate that is deposited with complementary SRRs. The floating terahertz metamaterial has an extremely large refractive index sensitivity of 532 GHz/RIU because its near field is not distributed over the substrate and also because the complementary SRRs confine the field above the substrate. The floating terahertz metamaterial senses bovine serum albumin (BSA) and the protein binding of BSA and anti-BSA as BSA, and anti-BSA solutions with low concentrations that are smaller than 0.150 μmol/L are sequentially dropped onto it. The floating terahertz metamaterial is a great achievement to develop protein sensors with extremely large refractive index sensitivities, and has the potential to sense dangerous viruses.
A Cognitive-Behavioral Stress Management Coaching
Authors: Traut-Mattausch Eva , Zanchetta Mirjam , Pömmer Martin 
Published: August 2021

AbstractIn this article, we present a theoretically well-founded coaching concept, which can be assigned to the cognitive-behavioral area and which aims to optimally deal with stress. The coaching concept is based on Lazarus’ transactional theory of stress and coping. The three coaching sessions based on this theory are described in as much detail as possible. We explain which exercises can be used and how – both during and between the coaching sessions – in order to provide the best possible support for stress management and goal attainment. The specific procedure is illustrated with the case study “Mr. Smith” and reflected from the coach’s perspective. The description of the cognitive-behavioral stress management coaching (abbreviated to CBSM coaching) and the case study therefore offer both suggestions for experienced coaches and a good guide for newcomers to the field. The effectiveness of the CBSM coaching has already been empirically proven. The results of this already published evaluation study will be presented in the overview. With the theory-based development and the practical presentation of the CBSM coaching concept, a contribution should be made to further close the gap that sometimes arises between coaching research and practice.

A New Distribution-Free Control Chart for Monitoring Process Median Based on the Statistic of the Sign Test
Authors: Ali Saber , Abbas Zameer , Zafar Nazir Hafiz , Riaz Muhammad , Abid Muhammad 
Published: August 2021

Abstract
Control charts are used to improve the quality of outputs in manufacturing, industrial, and service processes. The parametric control charts produce more false alarms and unacceptable out-of-control signals when the underlying distribution of the process is not normal. Nonparametric/distribution-free control charts are efficient alternatives to overcome the said situation. In this article, the performance of a distribution-free double exponentially weighted moving average (EWMA) chart has been investigated based on the sign test statistic under simple and ranked set sampling schemes. The run-length properties of the proposed charts have been evaluated and compared with nonparametric EWMA sign, parametric EWMA, and parametric double EWMA control charts, using different run-length measures. The comparison reveals the efficiency of the proposed chart over its alternatives in detecting small and medium shifts in the process location. A real-data application using the substrate manufacturing process has been provided to show the implementation of the proposed chart.

Background and Aims: Acute non-variceal upper gastrointestinal bleeding (UGIB) is associated with significant morbidity and mortality. Our aim was to evaluate the incidence, management, risk factors and outcomes of acute non-variceal UGIB in a population-based study from Hungary.
Methods: The present prospective one–year study involved six major community hospitals in Western Hungary covering a population of 1,263,365 persons between January 1 and December 31, 2016. Data collection included demographics, comorbidities endoscopic management, Glasgow-Blatchford score (GBS), Rockall score (RS) transfusion requirements, length of hospital stay and mortality.
Results: 688 cases of acute non-variceal UGIB were included with an incidence rate of 54.4 (95%CI: 50.5-58.6) per 100,000 per year. Endoscopy was performed within 12 hours in 71.8%. 5.3% of the patients required surgical treatment and the overall mortality was 13.5%. Weekend presentation was associated with increased transfusion requirements (p=0.047), surgery (p=0.016) and mortality (p=0.021). Presentation with hemodynamic instability or presence of comorbidities was associated with transfusion (p<0.001 both), second look endoscopy (p<0.001 both), re-bleeding (p<0.001 both), longer in-hospital stay (p<0.001 both) and mortality (p=0.017 and p<0.001). GBS was associated with transfusion requirement (AUC:0.82; cut-off: GBS >7points), while mortality was best predicted by the post-endoscopic RS (AUC:0.75; cut-off: RS >5points).
Conclusions: Incidence rates of acute non-variceal UGIB in Western Hungary are in line with international trends. Longer pre-hospital time, comorbidities, hemodynamic instability, weekend presentation, treatment with anticoagulants or non-steroidal anti-inflammatory drugs was associated with worse outcomes.
Foliage-browsing Lepidoptera (Insecta) in deciduous forests of Ukraine for the last 70 years
Authors: Meshkova Valentyna 
Published: August 2021

As insect development depends on temperature, so the change in biology, behavior habits, frequency, and severity of outbreaks of foliage-browsing insects considered pests can follow the climate change. The reactions of species to the same climate changes can be specific, therefore, an unpredictable change in their ratio in the community will affect the consequences of climate change.
The details of such changes must be studied to quantitatively assess future trends and the threats to deciduous forests. The aim of this research was to evaluate the representation in deciduous forests the foliage-browsing lepidopterous insects if different groups of size, lifestyle, voltinism, trophic relations, and ability to mass propagation in different periods of assessment for recent 70 years.
In the analysis, we used a list of 118 lepidopterous species of foliage-browsing insects of deciduous forests, compiled on the basis of archival data from 1940–1975, and in the course of our own field research from 1975 to the present in the forests of Ukraine. Following trends were expected to be confirmed for these time intervals: to increase the number of species of small size, the number of species with hidden lifestyle, multivoltine species, polyphagous species, and so-called indifferent species. For each species, all these parameters were identified and proportions of species of each category for certain time intervals (1940–1950, 1960–1970, 1980–1990, and 2010–2020). Their distribution for size, voltinism, lifestyle, trophic features, and outbreak potential at these time intervals was compared using χ2-test.
Among lepidopterous foliage-browsing insects of deciduous forests of Ukraine, the increase for recent 70 years was proved for the proportion of indifferent species (do not able to mass propagation), small species (with wingspan below 20 mm), as well as species with hidden (leaf-miners) and semi-hidden lifestyle (leaf-rollers). All trends are expressed the most obviously in 1940–1950 and further periods. The hypothesis about decrease the proportion of the univoltine and monophagous species for this period is not supported statistically.

Published: August 2021

The aim of this paper was to investigate audiological abnormalities and potential vestibular injury in a sample of vitiligo subjects. Thirty-five patients with non-segmental vitiligo (NSV) were enrolled in the study. They underwent pure tonal audiometry (PTA), vestibular Fitzgerald-Hallpike caloric test, C-VEM, and O-VEMP testing. The χ2 test and multiple regression analysis were performed. At PTA, 69% of patients presented with bilateral hearing loss, 8% monaural hearing loss, and 23% normal values. Bilateral caloric stimulations were performed and demonstrated that 14% of patients had a monolateral and 9% had a bilateral pathological response. VEMPs analysis showed that 20% of patients had no O-VEMPs response and 3% had no C-VEMPs response. Comparison between the normal values of healthy subjects and NSV patients showed an alteration of VEMPs in 44%. Multiple regression showed no statistical differences. We propose a specific diagnostic protocol employing PTA, bithermal caloric tests, C-VEMP, and O-VEMP testing to evaluate audio-vestibular damage. Our data were concordant with the anatomic-physiological melanocytic distribution and their possible degeneration linked with NSV.

Published: August 2021

Objectives: One of the main problems with polymethyl methacrylate (PMMA) used for the fabrication of oral removable appliances is plaque accumulation due to surface porosities. Incorporation of antimicrobial agents in this material might help tackle this problem. The aim of this study was to evaluate the antimicrobial activity of PMMA acrylic resin incorporated with propolis nanoparticles (PNPs).
Materials and Methods: Antimicrobial properties of acrylic resin incorporated with PNPs were assessed against Streptococcus mutans (S. mutans), Streptococcus sanguinis (S. sanguinis), Lactobacillus acidophilus (L. acidophilus) and Candida albicans (C. albicans). Acrylic discs were fabricated in four groups: A control group without PNPs and three experimental groups containing 0.5%, 1% and 2% concentrations of PNPs. Disc agar diffusion (DAD) test was performed to determine the antimicrobial effects of PNPs by measuring the microbial growth inhibition zones on Muller-Hinton agar plates. The eluted components test evaluated the viable counts of microorganisms in liquid medium after 24 and 72h. Finally, biofilm inhibition test assessed the efficacy of PNPs for inhibition of biofilm formation. P<0.05 was considered significant.
Results: The acrylic discs failed to produce microbial inhibition zones in the DAD test. Discs containing 1% and 2% nanoparticles showed anti-biofilm effects on all four microbial species. The colony counts of all microorganisms significantly decreased following exposure to liquids containing nanoparticles after 24 and 72h in eluted component test.
Conclusion: PMMA acrylic discs incorporated with PNPs presented some antimicrobial properties against S. mutans, S. sanguinis, L. acidophilus, and C. albicans.

Authors: Singh Rajwent , Arora A.K. , Rai T.S. , Chandra Mudit 
Published: August 2021

Background: Group B streptococcus (GBS) or Streptococcus agalactiae is an important pathogen associated with bovine mastitis. The organism is also of public health consequences and may cause variety of infections ranging from neonatal sepsis, pneumonia and meningitis to localized infections and urinary tract infection or arthritisin adult humans. Widespread use of antibiotics in veterinary medicine has led to development of resistance among the pathogens. So there is need for surveillance of antimicrobial resistance to ensure effective treatment. Methods: Milk samples collected from mastitis affected animals were processed for isolation of Streptococcus agalactiae. The isolates were tested for antimicrobial susceptibility. Molecular characterisation was carried out by PCR to study the occurrence of resistance marker genes and virulence marker genes. RAPD was carried out to study genetic diversity among the isolates. Result: Six isolates of S. agalactiae were obtained from 182 milk samples. Highest resistance was observed against co-trimoxazole and tetracycline followed by ampicillin. tetM gene and tetO genes could be amplified in four and three isolates, respectively. None of the isolates showed amplification for ermA, ermB, mefA and mefE genes. Three isolates were positive for the five virulence genes tested (glnA, cfb, hylB, scaA and cyl). RAPD analysis demonstrated great intraspecific genetic diversity among the streptococcal isolates.
