Published: May 2022

Objective

Men are at greater risk from COVID-19 than women. Older, overweight men, and those with type 2 diabetes, have lower testosterone concentrations and poorer COVID-19-related outcomes. We analysed the associations of premorbid serum testosterone concentrations, not confounded by the effects of acute SARS-CoV-2 infection, with COVID-19-related mortality risk in men.

Design

This study is a United Kingdom Biobank prospective cohort study of community-dwelling men aged 40–69 years.

Methods

Serum total testosterone and sex hormone-binding globulin (SHBG) were measured at baseline (2006–2010). Free testosterone values were calculated (cFT). the incidence of SARS-CoV-2 infections and deaths related to COVID-19 were ascertained from 16 March 2020 to 31 January 2021 and modelled using time-stratified Cox regression.

Results

In 159 964 men, there were 5558 SARS-CoV-2 infections and 438 COVID-19 deaths. Younger age, higher BMI, non-White ethnicity, lower educational attainment, and socioeconomic deprivation were associated with incidence of SARS-CoV-2 infections but total testosterone, SHBG, and cFT were not. Adjusting for potential confounders, higher total testosterone was associated with COVID-19-related mortality risk (overall trend P = 0.008; hazard ratios (95% CIs) quintile 1, Q1 vs Q5 (reference), 0.84 (0.65–1.12) Q2:Q5, 0.82 (0.63–1.10); Q3:Q5, 0.80 (0.66–1.00); Q4:Q5, 0.82 (0.75–0.93)). Higher SHBG was also associated with COVID-19 mortality risk (P = 0.008), but cFT was not (P = 0.248).

Conclusions

Middle-aged to older men with the highest premorbid serum total testosterone and SHBG concentrations are at greater risk of COVID-19-related mortality. Men could be advised that having relatively high serum testosterone concentrations does not protect against future COVID-19-related mortality. Further investigation of causality and potential underlying mechanisms is warranted.
Drying of thick foam formed mats comprising chemithermomechanical pulp fibers
Authors: Timofeev Oleg N. , Jetsu Petri , Keränen Janne T.
Published: May 2022

This paper focuses on the drying studies of foam-formed wood fibre based relatively thick materials via infrared drying, impingement drying, and microwave drying. The drying experiments were carried out for materials with three initial moisture ratios and thickness levels. Material selection was guided by the possibility of using these kinds of materials in packaging and construction applications. The motivation for this study was the fact that in water-based manufacturing a lot of energy is consumed during the drying phase; therefore, the better understanding of drying kinetics is essential for improving the environmental friendliness and cost efficiency of material production. The results revealed differences in the results of drying methods and limitations for thick, porous wood fibre-based materials. The differences in these methods affected the drying rates and material quality, which both can arise as the limiting factor for material production. The highest drying rate was observed using microwave drying, the intermediate drying rate was achieved using impingement drying, and the lowest using infrared drying.

Published: May 2022

A novel biobased porous aerogel was synthesized using physical mixing, freeze-drying, and in-situ growth methods. Zeolitic imidazolate frameworks-8 (ZIF-8) were grafted onto the surface of the CS/CNF solid composite to form a ZIF-8@CS/CNF aerogel. The structural characteristics and the adsorption potential of the ZIF-8@CS/CNF aerogel were investigated. It was found that the specific surface area of the ZIF-8@CS/CNF aerogel was 206 m2/g, and the water stability of the CNF aerogel was enhanced by incorporating the CS. Meanwhile, the adsorption isotherm and kinetics of the composite aerogel fit the pseudo-second-order kinetic model (R2 = 0.96) and the Langmuir isotherm model (R2 = 0.97) with the copper(II) oxide (Cu(II)) theoretical adsorption capacity of 245 mg/g, respectively. Furthermore, this aerogel, which combined metal-organic frameworks (MOFs) and CNF, was easy to fabricate and it was biodegradable. These characteristics suggest it has a broad potential for wastewater treatment.

Published: May 2022

In order to improve the sound absorption performance of the light-frame timber construction wall, this paper combined the aperture embedded wall unit structure with the actual building wall structure based on the Helmholtz resonance structure principle to design and fabricate two sets of wall structures: a new aperture embedded Helmholtz resonance structure (experimental group) and a conventional structure (control group). The sound absorption coefficients of the two wall structures were measured by the reverberation chamber test, and related analysis was carried out. The results showed that the aperture embedded Helmholtz resonance wall structure exhibited good sound absorption performance in the low frequency range; in particular, a perfect sound absorption effect was basically achieved at a frequency of 100 Hz. Compared with the conventional wall structure, the sound absorption performance of the aperture embedded Helmholtz resonance wall structure in the test frequency range was enhanced greatly. While the value of the sound absorption coefficient was increased in the low frequency range, the bandwidth of sound absorption frequency was expanded to a certain extent, and the average sound absorption coefficient and noise reduction coefficient were both improved. This paper explored the applicability of Helmholtz resonance structure in practical wall structure. The research results could provide reference for reducing indoor noise pollution and creating a better living environment.

Published: May 2022

The future of the economies of various nations across the globe lies in the entrepreneurial trends and activities. Entrepreneurship in this regard is viewed from the activities of Small, Medium and Micro Enterprises (SMMEs). Entrepreneurial activities are also viewed as development driving tool for rural societies. However, necessary skills are needed for such desired goal to be achieved and the education provided by institutions of learning is one by which entrepreneurial expertise can be attained. Conversely, entrepreneurship education is not considered as a major subject receiving due attention in South African institutions of learning. Hence, this study explores the impact of entrepreneurship education on the performance of Small, Medium and Micro Enterprises (SMMEs). Review method was adopted for this study. Thus, relevant literatures were reviewed. The findings of the study amongst others show that relevant skills are needed for entrepreneurial activities to thrive in rural societies and aid the needed development. Also, entrepreneurship education tends to impact entrepreneurial activities. The study therefore recommends amongst others that entrepreneurship education should be promoted in rural based institutions of learning in South Africa taking into cognizance the needs and demands of the communities and its surroundings where the institutions are situated.

As the science of adversity and resilience advances, and public awareness of the health consequences of stress grows, primary care providers are being increasingly asked to address the effects of adverse experiences on child wellbeing. Given limited tools for assessing these effects early in life, the authors explore how enhanced capacity to measure stress activation directly in young children could transform the role and scope of pediatric practice. When employed within a trusted relationship between caregivers and clinicians, selective use of biological measures of stress responses would help address the documented limitations of rating scales of adverse childhood experiences as a primary indicator of individual risk and strengthen the ability to focus on variation in intervention needs, assess their effectiveness, and guide ongoing management. The authors provide an overview of the potential benefits and risks of such expanded measurement capacity, as well as an introduction to candidate indicators that might be employed in an office setting. The ultimate value of such measures for both pediatricians and parents will require vigilant attention to the ethical responsibilities of assuring their correct interpretation and minimizing the harm of inappropriate labeling, especially for children and families experiencing the hardships and threats of racism, poverty, and other structural inequities. Whereas much work remains to be done to advance measurement development and ensure its equitable use, the potential of validated markers of stress activation and resilience to strengthen the impact of primary health care on the lives of young children facing significant adversity demands increased attention.
Ultrasound-guided percutaneous core-needle biopsy of focal pancreatic lesions –
practical aspectss
Authors: Rogowska Agnieszka Zofia
Published: May 2022

Ultrasound-guided percutaneous core-needle biopsy is an excellent diagnostic tool
for solid pancreatic lesions. It allows for identifying neoplastic pancreatic tumors
with nearly 100% sensitivity, specificity and accuracy. Unresectable tumor assessment
prior to planned palliative treatment is the primary indication for percutaneous
pancreatic tumor biopsy. In the case of potential tumors eligible for radical surgery,
endosonography-guided biopsy is used, if clinically necessary, to avoid the peritoneal
spread of tumor cells during puncture. The possibility of obtaining a specimen for a
detailed microscopic assessment during an easily accessible and simple procedure is the
main advantage of core-needle biopsy over the low, yet higher when compared to other
biopsy techniques, risk of complications. Obtaining tissue samples for molecular
analysis is essential for palliative targeted therapy in pancreatic cancer and may
become the main indication for the common core-needle biopsy of inoperable pancreatic
tumors in the near future. The present paper describes the indications and the technique
for core-needle biopsy in pancreatic tumors. Based on the studies published to date, the
safety of the procedure, significant complications, including bleeding in particular,
and the diagnostic sensitivity and specificity, also compared to other biopsy
techniques, have been summarized. The present paper may contribute to the introduction
of core-needle biopsy of pancreatic masses into clinical practice.

Sarcoidosis is a systemic inflammatory disease of unknown aetiology. Given its
complex clinical presentation, the disorder frequently causes diagnostic challenges. In
most cases, the primary manifestation is in the lungs and mediastinum. Breast
involvement as the primary manifestation of sarcoidosis is rare, accounting for less
than 1% of cases. The authors present the case of a 44-year-old woman whose disease
first manifested as multiple non-specific BIRADS 4 lesions in both breasts, accompanied
by axillary lymphadenopathy, detected by ultrasound examination. The lesions were not
visible on mammography. The course of the disease was clinically silent, with
intermittent remissions, until the complete resolution of focal breast lesions on
ultrasound after two years of follow-up. The paper presents an algorithm for the
management of multifocal breast pathology with associated lymphadenopathy, which led to
the prompt verification of sarcoidosis.

Published: May 2022

Fungal disease resistant (PIWI) interspecific grape varieties are playing an important role as an alternative for organic wine production. Organic (bio) wines are demanded by numerous conscious consumers around the globe. They choose this kind of wines predominantly because of the absence of synthetic pesticides, fertilisers and sustainable agriculture. Resistant grape growing moreover results in additional environmental and health benefits. Nero and Bianca are among Hungary's most promising interspecific grape cultivars gaining international interest recently, there are, however, limited vitivinicultural knowledge on them. Our aim was to examine the flavonoid and anthocyanin composition for both interspecific varieties during different harvest times in two consecutive vintages. The date of harvest and vintage played a significant effect on grape and wine quality.

We report on the occurrence of Choeroniscus godmani (Thomas, 1903) in Brazil and Panama. The Panama record fills a distribution gap for the species in Central America. The three records from Brazil are from the Amazonia in the state of Pará, and from the Cerrado and an Amazonia/Cerrado ecotone in the state of Mato Grosso. At two localities in Brazil, C. minor, a larger species of Choeroniscus, was also recorded. These new records extend the distribution of C. godmani by 2,065 km south to central South America. One of the Brazilian specimens represents the first record of supernumerary incisors in C. godmani.
DNA Polymerase β in the Context of Cancer
Authors: Sawyer Danielle L. , Sweasy Joann B.
Published: May 2022

DNA polymerase beta (Pol β) is a 39 kD vertebrate polymerase that lacks proofreading ability, yet still maintains a moderate fidelity of DNA synthesis. Pol β is a key enzyme that functions in the base excision repair and non-homologous end joining pathways of DNA repair. Mechanisms of fidelity for Pol β are still being elucidated but are likely to involve dynamic conformational motions of the enzyme upon its binding to DNA and deoxynucleoside triphosphates. Recent studies have linked germline and somatic variants of Pol β with cancer and autoimmunity. These variants induce genomic instability by a number of mechanisms, including error-prone DNA synthesis and accumulation of single nucleotide gaps that lead to replication stress. Here, we review the structure and function of Pol β, and we provide insights into how structural changes in Pol β variants may contribute to genomic instability, mutagenesis, disease, cancer development, and impacts on treatment outcomes.

Published: May 2022

This paper benchmarks the challenges involved with major sea, or fixed link, bridge crossings from their planning to final construction. An overview of existing major fixed link crossings globally, including statistical information such as length and inflation-adjusted project costs, is given. Data for well-known links such as the Øresund Crossing in Europe and the more recent Hong Kong–Zhuhai–Macau Bridge are included. The construction methods required to surmount the challenges of bridging such crossings and how advancements are making long-mooted crossings more feasible are discussed. Statistics on the construction durations of these crossings are presented and links between construction time, cost aspects and carbon dioxide emissions are considered. Finally, the paper looks to the future and considers how the data can be used to better bound estimates of time, costs, and emissions for fixed link projects. The viability of some of the more notable future fixed link projects is also addressed.

Authors: Vujčić Bok Valerija , Šola Ivana , Rusak Gordana
Published: May 2022

Research background. Citrus limon (L.) Burm lemon juice is rich in many important natural chemical components (flavonoids, citric acid and vitamin C) and its use in traditional medicine is well known. Formulations of lemon juice with fruit polyphenols in beverages have been investigated, but there is very little information about their ability to modulate the digestive behaviour of polyphenols. The goal of this study is to determine the stability and digestive availability of spinach (Spinacia oleracea L.) polyphenols by adding different volume fractions of lemon juice (0, 2, 5, 10 and 20 %) during in vitro digestion.
Experimental approach. The content of polyphenols and other abundant compounds including nitrates, oxalic acid and l-ascorbic acid in spinach formulation with various volume fractions of lemon juice were measured in predigested and digested samples using in vitro human digestion model. Antioxidant and α-amylase inhibitory activities of spinach lemon juice formulation were also measured.
Results and conclusions. The highest increases in total polyphenols, total flavonoids, total phenolic acids, oxalic acid and nitrate content were noted in predigested and almost all digested spinach samples formulated with the highest volume fraction of lemon juice. In the same sample, the content of individual compounds significantly increased after salivary (l-ascorbic acid), initial (p-coumaric acid) and intestinal (quercetin) phase of digestion. High bioaccessibility of polyphenols and l-ascorbic acid in all phases of digestion was observed in almost all spinach lemon juice formulations, with the exception of nitrates in gastric and intestinal phases and oxalic acid in the intestinal phase, which had moderate bioaccessibility.
Novelty and scientific contribution. For the first time the stability and digestive availability of spinach polyphenols, oxalic acid, nitrates and l-ascorbic acid were tested with the addition of different volume fractions of lemon juice. The pH of lemon juice and its l-ascorbic acid content increase the stability and availability of polyphenols in spinach lemon juice formulation during in vitro digestion. Antioxidant and α-amylase inhibitory activities increase in dose-dependent manner after lemon juice addition. Accordingly, spinach formulated with 20 % of lemon juice appears as the best source of dietary polyphenols with antioxidant and antidiabetic activities and nitrates that may be used as a functional drink.

Este estudio se propuso comprender los significados que atribuyen profesores y estudiantes a las características que consideran prioritarias en un docente excelente (por ejemplo, experticia en la disciplina, ser buen comunicador) y las relaciones que establecen entre ellas. Se administró un cuestionario sobre características de docentes de calidad (Teacher Behavior Checklist) a 44 profesores y 37 estudiantes universitarios, de diferentes disciplinas (Ciencias, Derecho) y una entrevista semi-estructurada sobre las características esenciales para definir la excelencia docente. Igualmente, se empleó el análisis temático (Braun y Clark, 2006) como estrategia de análisis. Los resultados indicaron que los participantes consideran centrales tres características: ser comunicador efectivo; ser competente en su disciplina; y ser respetuoso con los estudiantes. Asimismo, tanto para profesores como estudiantes, la experticia en la disciplina no agota el concepto de excelencia, sino que otros aspectos de tipo relacional (respeto, comunicación) son igualmente importantes. Estos resultados coinciden con los planteados por otros autores latinoamericanos que utilizan modelos tanto inductivos como deductivos sobre la evaluación de la excelencia docente. Se recomienda que futuros estudios evalúen las concepciones de los estudiantes en diferentes momentos del año académico y cuenten con muestras más representativas de diferentes disciplinas que permitan establecer comparaciones por áreas del conocimiento.

Com o avanço da globalização, e o consequente crescimento do fluxo de pessoas entre diferentes nações, novas formações familiares vêm sendo compostas. Nessa conjuntura, e diante de posterior rompimento desses relacionamentos, tornam-se mais comuns casos de sequestros interparentais que objetivam a guarda exclusiva do infante por um dos genitores. Por essa razão, o presente trabalho tem por intento analisar os mecanismos internacionais e nacionais de proteção às crianças vítimas do sequestro interparental, bem como a observação dos Direitos Humanos. Nesse ínterim, com o intuito de solucionar tal questão, a Convenção da Haia estabelece como regra, a fim de assegurar o melhor interesse do menor, o retorno desse à sua residência habitual, determinando, porém, exceções, as quais serão objeto do corrente trabalho. A metodologia do trabalho consiste em uma pesquisa de levantamento bibliográfico, bem como em análise jurisprudencial.

Türkiye-Gürcistan işbirliği kapsamında, ‘‘Gürcistan Kavakçılığını Geliştirme’’ projesi hazırlanarak, uygulamaya geçirilmiştir. Projenin ilk aşamasını oluşturan fidanlık denemeleri için Kavak ve Hızlı Gelişen Orman Ağaçları Araştırma Enstitüsü Müdürlüğü’ne ait klon bankasından 20 adet kavak klonu seçilmiştir. Kontrol klonu olarak Gürcistan’ın doğal kavak türleri (Populus alba ve Populus pyramidalis) kullanılmıştır. Gürcistan’ın Gori ve Jighaura fidanlıklarında iki deneme alanı tesis edilmiştir. Varyans analizi sonuçlarına göre, klonların çap ve boy büyümeleri ile yaşama oranları açısından hem bölgeler (Gori ve Jighaura) hem de bölgelerde klonlar arasında farklılık olduğu belirlenmiştir. Genel olarak denenen klonlar, kontrol materyallerinden daha başarılı olmakla birlikte Gori bölgesinde İzmit ile 89M044, Jighaura bölgesinde ise 89M060 ile 89M061 klonları en iyi büyüme performansını göstermişlerdir. Her iki deneme alanın birlikte değerlendirilmesi sonucunda ise, 89M044 klonu en başarılı klon olmuştur.

The purpose of the study was to mine, compile and analyze the published data on breast cancer (BC) systematization, diagnosis and treatment. In the current review, modern approaches in BC subtypes diagnosis based on genomic profiling, miRNA expression pattern analysis, SNP analysis in BRCA1 and BRCA2 genes, as well as proteomic mapping as essential components of the disease peculiarities improving the prognostic outcome were compiled and analyzed. Further, tumor-initiating stem-like cells as a factor affecting both prognosis and treatment choice for BC are considered and evaluated. And finally, modern principles of enhancing tumor sensitivity to therapeutic effects of anticancer drugs, which comprise the use of cytostatics in condensed modes, combining drugs, which exert different mechanisms of cytotoxicity, as well as the introduction of new chemotherapy drugs into therapeutic practice, including those targeted against the common metabolic pathways both in stem-like and committed breast cancer cells, are compiled and discussed. The analysis indicates that the current paradigm in BC treatment is development and implementation of the newest methods for diagnosis of BC sybtypes, which, being combined with those already implemented, would allow the administration of treatment according to the individual peculiarities of a tumor.

Objective: to elaborate a new algorithm, based on serum CA125, HE4 and age, to assess the risk of malignancy in premenopausal patients with pelvic mass, which performs better than Risk of Ovarian Malignancy Algorithm (ROMA).

Materials and methods. The training dataset included 284 premenopausal patients operated because of the presence of pelvic mass, out of which there were 249 patients with benign diseases and 35 patients with malignant or borderline tumors. A novel algorithm, based on serum HE4, CA125 and patient’s age as variables, has been developed. This algorithm was named Risk of Ovarian Cancer Kazan Index (ROCK-I). The validating dataset consisted of 227 consecutively operated premenopausal patients with pelvic mass out of which there were 193 cases of benign diseases, 27 cancers and 7 borderline ovarian tumors (BOT).

Results. In the validating dataset ROCK-I and ROMA demonstrated 15 and 30 false positive results respectively. Thus the specificities of ROCK-I and ROMA were 92.2 % and 84.5 %, respectively (р = 0.017). The sensitivities of ROCK-I and ROMA for the joint group of Epithelial ovarian cancers (EOC) (all stages) together with BOT stage IC2–III were 96.3 % and 92.6 %, respectively (p = 0.55). For all malignant disease (all stages) together with BOT stage IC2–III the sensitivities were 90 % and 86.7 %, respectively (p = 0.69). The positive predictive values of ROCK-I and ROMA were 65.1 % and 47.4 %, respectively (p = 0.07). When the scenario of discrimination “benign disease vs the joint group of EOC (all stages) together with BOT stage IC2–III” was used, ROC-AUC of ROCK-I, ROMA and CA125 were 0.988, 0.946 and 0.937. The difference in ROC-AUC between ROCK-I and CA125 was statistically significant (p = 0.01) while the difference between ROMA and CA125 was not (p = 0.79).

Conclusion. The proposed ROCK-I has demonstrated greater diagnostic performance than both ROMA and CA125 in the analyzed dataset. If an independent validation shows similar or even slightly lower superiority of ROCK-I over ROMA, it may provide a new basis of routine-use of HE4 in premenopausal patients with pelvic mass.
