On the efficiency of entomopathogenic nematodes (Rhabditida: Heterorhabditidae and Steinernematidae) on rust red flour beetle, Tribolium castaneum (Herbst.) (Coleoptera: Tenebrionidae)
Authors: Erdoğuş Fatma Dolunay 
Published: August 2021

Abstract
Background
The rust red flour beetle, Tribolium castaneum (Herbst.) (Coleoptera: Tenebrionidae) is a serious pest of stored grains and grain products across the world. This beetle is hold a significant place in Turkey by causing damages on stored products. T. castaneum primarily attacks milled grain and its derivates. Entomopathogenic nematodes (EPNs) are regarded as extremely an important biological control agent. EPNs kills their hosts within 48 h by the bacteria they carry.

Results
Efficacies of 4 isolates of EPNs Steinernema carpocapsae (Tokat Bakisli 05), S. feltiae (Tokat-Emir), Heterorhabditis bacteriophora (TOK-20) and H. bacteriophora (11-KG) against T. castaneum was investigated under laboratory conditions. The experiments were carried out thrice with 10 replicates at 2 different temperatures (15 and 25 ºC). EPNs isolates were tested at 3 different concentrations (250, 500 and 1000 IJs/ml) with a pure water as control. The overall mortality caused by H. bacteriophora (Kg11) was significantly higher than the other EPN species. At 25 ºC, H. bacteriophora (Kg11) at the highest concentration (1000 IJs/ml) caused 87.6% mortality after 120 h., followed by S. carpocapsae and S. feltiae with 79.22 and 75.3% mortality rates, respectively. The mortality percentages exhibited by all nematodes’ species at both temperatures were lowest at the concentration of (250 IJs/ml). At 15 °C, H. bacteriophora (Kg11) caused (55.2%) mortality rate at the highest concentration (1000 IJs / ml) after 120 h.

Conclusion
The study suggested that these nematodes were efficient and could be recommended to control T. castaneum in its biological control programs.
Days of the Cavemen? Adorno, Spengler, and the Anatomy of Caesarism
Authors: Immanen Mikko 
Published: August 2021

Abstract
This article addresses the controversial question of Theodor W. Adorno’s debt to right-wing Zivilisationskritik by a close reading of his essay “Spengler after the Decline” (1950). The article shows that despite Adorno’s harsh polemics against Oswald Spengler’s Decline of the West (1918, 1922), he sought to make Spengler’s analysis of Weimar Germany’s undemocratic tendencies—“Caesarism”—serve progressive ends. However, Adorno’s essay was not just an effort at “coming to terms with the past” in Adenauerian West Germany. Reading the essay’s original 1941 version together with Adorno’s correspondence with Max Horkheimer sheds light on Spengler as an overlooked key (next to Max Weber, Sigmund Freud, and Walter Benjamin) to their Dialectic of Enlightenment, written in 1941–44. Adorno’s daring effort to appropriate Spengler’s analysis of Caesarism makes Adorno’s critical theory an asset in understanding today’s authoritarian populism.

Published: August 2021

ABSTRACT
Selectins and integrins are key players in the adhesion and signaling cascade that recruits leukocytes to inflamed tissues. Selectin binding induces β2 integrin binding to slow leukocyte rolling. Here, a micropipette was used to characterize neutrophil adhesion to E-selectin and intercellular adhesion molecule-1 (ICAM-1) at room temperature. The time-dependent adhesion frequency displayed two-stage kinetics, with an E-selectin-mediated fast increase to a low plateau followed by a slow increase to a high plateau mediated by intermediate-affinity binding of integrin αLβ2 to ICAM-1. The αLβ2 activation required more than 5 s contact to E-selectin and spleen tyrosine kinase (Syk) activity. A multi-zone channel was used to analyze αLβ2 activation by P-selectin in separate zones of receptors or antibodies, finding an inverse relationship between the rolling velocity on ICAM-1 and P-selectin dose, and a P-selectin dose-dependent change from bent to extended conformations with a closed headpiece that was faster at 37°C than at room temperature. Activation of αLβ2 exhibited different levels of cooperativity and persistent times depending on the strength and duration of selectin stimulation. These results define the precise timing and kinetics of intermediate activation of αLβ2 by E- and P-selectins.
The small GTPase KlRho5 responds to oxidative stress and affects cytokinesis

Published: August 2021

ABSTRACT
Rho5 is the yeast homolog of the human small GTPase Rac1. We characterized the genes encoding Rho5 and the subunits of its dimeric activating guanine-nucleotide-exchange factor (GEF), Dck1 and Lmo1, in the yeast Kluyveromyces lactis. Rapid translocation of the three GFP-tagged components to mitochondria upon oxidative stress and carbon starvation indicate a similar function of KlRho5 in energy metabolism and mitochondrial dynamics as described for its Saccharomyces cerevisiae homolog. Accordingly, Klrho5 deletion mutants are hyper-resistant towards hydrogen peroxide. Moreover, synthetic lethalities of rho5 deletions with key components in nutrient sensing, such as sch9 and gpr1, are not conserved in K. lactis. Instead, Klrho5 deletion mutants display morphological defects with strengthened lateral cell walls and protruding bud scars. The latter result from aberrant cytokinesis, as observed by following the budding process in vivo and by transmission electron microscopy of the bud neck region. This phenotype can be suppressed by KlCDC42G12V, which encodes a hyper-active variant. Data from live-cell fluorescence microscopy support the notion that KlRho5 interferes with the actin moiety of the contractile actomyosin ring, with consequences different from those previously reported for mutants lacking myosin.
Analyzing normal and disrupted leukemic stem cell adhesion to bone marrow stromal cells by single-molecule tracking nanoscopy
Authors: Gorshkova Oksana , Cappaï Jessica , Maillot Loriane , Sergé Arnauld 
Published: August 2021

ABSTRACT
Leukemic stem cells (LSCs) adhere to bone niches through adhesion molecules. These interactions, which are deeply reorganized in tumors, contribute to LSC resistance to chemotherapy and leukemia relapse. However, LSC adhesion mechanisms and potential therapeutic disruption using blocking antibodies remain largely unknown. Junctional adhesion molecule C (JAM-C, also known as JAM3) overexpression by LSCs correlates with increased leukemia severity, and thus constitutes a putative therapeutic target. Here, we took advantage of the ability of nanoscopy to detect single molecules with nanometric accuracy to characterize junctional adhesion molecule (JAM) dynamics at leuko-stromal contacts. Videonanoscopy trajectories were reconstructed using our dedicated multi-target tracing algorithm, pipelined with dual-color analyses (MTT2col). JAM-C expressed by LSCs engaged in transient interactions with JAM-B (also known as JAM2) expressed by stromal cells. JAM recruitment and colocalization at cell contacts were proportional to JAM-C level and reduced by a blocking anti-JAM-C antibody. MTT2col revealed, at single-molecule resolution, the ability of blocking antibodies to destabilize LSC binding to their niches, opening opportunities for disrupting LSC resistance mechanisms.

Published: August 2021

Fourier ptychographic microscopy (FPM), as an emerging computational imaging method, has been applied to quantitative phase imaging with resolution bypassing the physical limit of the detection objective. Due to the weak illumination intensity and long image acquisition time, the achieved imaging speed in current FPM methods is still low, making them unsuitable for real-time imaging applications. We propose and demonstrate a high-speed FPM method based on using laser illumination and digital micro-mirror devices for illumination angle scanning. In this new, to the best of our knowledge, FPM method, we realized quantitative phase imaging and intensity imaging at over 42 frames per second (fps) with around 1 µm lateral resolution. The quantitative phase images have revealed membrane height fluctuations of red blood cells with nanometer-scale sensitivity, while the intensity images have resolved subcellular features in stained cancer tissue slices.
Awareness and use of nonoccupational HIV post-exposure prophylaxis and factors associated with awareness among MSM in Beijing, China
Authors: Sun Yanming , Li Guiying , Lu Hongyan 
Published: August 2021

Background
Human immunodeficiency virus (HIV) sexual transmission among men who have sex with men (MSM) has increased markedly in Beijing, China, during the past decade. Nonoccupational HIV post-exposure prophylaxis (nPEP) is a highly efficacious biomedical prevention strategy that significantly reduces HIV-transmission risk. This study examined nPEP awareness among MSM and the factors influencing it.

Methods
Consecutive, cross-sectional MSM surveys were conducted from April to August of 2018 and 2019. Demographic data as well as that on behavior and awareness regarding nPEP was collected. Factors influencing nPEP awareness were assessed using univariate and multivariable logistic regression.

Results
There were 1,202 eligible responders recruited. Of the responders, 42.5% had nPEP awareness, and 59.9% expressed interest in receiving nPEP in the future, if required. Greater odds of nPEP awareness were associated with younger age, higher education level (adjusted odds ratio [aOR]: 4.011, 95% confidence interval [CI]: 2.834–5.678, P<0.001), higher income, use of the Internet to meet sexual partners (aOR: 2.016, 95% CI: 1.481–2.744, P<0.001), greater HIV-related knowledge (aOR: 3.817, 95% CI: 1.845–7.899, p<0.001), HIV testing (aOR: 2.584, 95% CI: 1.874–3.563, p<0.001), and sexually transmitted infections (aOR: 1.736, 95% CI: 1.174–2.569, P = 0.006). Lower odds of nPEP awareness were associated with greater stigma score (aOR: 0.804, 95% CI: 0.713–0.906, P<0.001).

Conclusions
The findings indicate suboptimal awareness and low utilization of nPEP in Beijing and highlight nPEP inequities among MSM with stigma. Strengthening the training of health service providers and peer educators in reducing stigma and disseminating nPEP knowledge is imperative.

Published: August 2021

Background
Prediction models should be externally validated to assess their performance before implementation. Several prediction models for coronavirus disease-19 (COVID-19) have been published. This observational cohort study aimed to validate published models of severity for hospitalized patients with COVID-19 using clinical and laboratory predictors.

Methods
Prediction models fitting relevant inclusion criteria were chosen for validation. The outcome was either mortality or a composite outcome of mortality and ICU admission (severe disease). 1295 patients admitted with symptoms of COVID-19 at Kings Cross Hospital (KCH) in London, United Kingdom, and 307 patients at Oslo University Hospital (OUH) in Oslo, Norway were included. The performance of the models was assessed in terms of discrimination and calibration.

Results
We identified two models for prediction of mortality (referred to as Xie and Zhang1) and two models for prediction of severe disease (Allenbach and Zhang2). The performance of the models was variable. For prediction of mortality Xie had good discrimination at OUH with an area under the receiver-operating characteristic (AUROC) 0.87 [95% confidence interval (CI) 0.79–0.95] and acceptable discrimination at KCH, AUROC 0.79 [0.76–0.82]. In prediction of severe disease, Allenbach had acceptable discrimination (OUH AUROC 0.81 [0.74–0.88] and KCH AUROC 0.72 [0.68–0.75]). The Zhang models had moderate to poor discrimination. Initial calibration was poor for all models but improved with recalibration.

Conclusions
The performance of the four prediction models was variable. The Xie model had the best discrimination for mortality, while the Allenbach model had acceptable results for prediction of severe disease.

Authors: Woldekidan Nigist Alemayehu , Mohammed Ammas Siraj , Degu Amsalu , Tadiwos Yohannes 
Published: August 2021

Background
Psychiatric patients are at increased risk of being overweight or obese, and subsequently develop metabolic syndrome. Nevertheless, data regarding associated factors for weight gain are limited and inconsistent.

Objective
The present study aimed to determine the risk of metabolic syndrome and its associated factors among psychiatric patients.

Method
A cross-sectional quantitative study was conducted among all psychiatric patients at the Psychiatric Unit of the University of Gondar Comprehensive Specialized Hospital from March 1- April 1, 2018. All eligible psychiatric patients were interviewed about their socio-demographic status,and clinical characteristics and useful parameters for the study were recorded from the medical records of the patients and by measuring waist to height ratio. Descriptive statistics were used to summarize baseline information.Binary logistic regression was used to determine the associated factors and P-value <0.05 and confidence interval (CI) of 95% were used as cut off points for determining statistical significance.

Result
From 300 patients included in the study, 168(56%) patients were females,and around 50.3% of the study participants had low literacy levels. As per waist to a height ratio scale, 58% (174) of the patients had a risk of metabolic syndrome. The Binary logistic regression analysis indicated that sex (p-<0.0001), occupation (p -0.032), marital status (p-0.006), and distance from the hospital (p<0.0001) were statistically significant determinants of metabolic syndrome risk in the psychiatric patient in our setting.

Conclusion
The majority of the psychiatric patients in the study setting had a risk of metabolic syndrome. Sex, marital status, employment status, and distance to the hospital were significantly associated with metabolic syndrome. Routine physical and laboratory investigations to detect metabolic syndrome are indispensable in psychiatric patients to prevent cardiovascular complications.
The impact of chronic comorbidities at the time of breast cancer diagnosis on quality of life, and emotional health following treatment in Canada
Authors: Arneja Jasleen , Brooks Jennifer D. 
Published: August 2021

Introduction
Advances in breast cancer screening and treatment have led to an increasing number of breast cancer survivors. The objective of this study was to determine the impact of comorbidities on self-reported quality of life (QOL) and emotional health following a breast cancer diagnosis and treatment.

Methods
Women with a personal history of breast cancer (N = 3,372) were identified from the cross-sectional Canadian Partnership Against Cancer (CPAC) Experiences of Cancer Patients in Transitions Survey. Multinomial (nominal) logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) for the relationship between burden of comorbidities and overall QOL and emotional health (very poor/poor, fair, good, very good).

Results
Of the 3,372 participants, 57% reported at least one chronic condition at the time of breast cancer diagnosis. As the number of chronic conditions at diagnosis increased, the odds of reporting worse quality of life and emotional health following treatment also increased. Specifically, compared to women reporting very good QOL, for each additional chronic condition, women reported significantly higher odds of reporting good (OR = 1.22, 95% CI: 1.12, 1.32), fair (OR = 1.76, 95% CI: 1.58, 1.96), or poor/very poor (OR = 2.31, 95% CI: 1.86, 2.88) QOL. Similarly, for each additional comorbidity, women reported significantly higher odds of reporting good (OR = 1.17, 95% CI: 1.07, 1.28), fair (OR = 1.63, 95% CI: 1.46, 1.82), or poor/very poor (OR = 2.17, 95% CI: 1.81, 2.60) emotional health, relative to very good emotional health.

Conclusion
Breast cancer survivors coping with a high comorbidity burden experience worse overall QOL and emotional health following treatment. This highlights the importance of integrating information on comorbidities into survivorship care to improve the experience and overall outcomes of patients with complex needs.
Barriers to timely disclosure of HIV serostatus: A qualitative study at care and treatment centers in Dar es Salaam, Tanzania
Authors: Ismail Neelam , Matillya Nancy , Ratansi Riaz , Mbekenga Columba 
Published: August 2021

Introduction
Disclosure of Human Immunodeficiency Virus (HIV) status is important to prevent the spread of HIV and maintain the health of people living with HIV, their spouses, and the community. Despite the benefits of disclosure, many people living with HIV delay disclosing their status to those close to them thereby increasing the risk for disease transmission. This study aimed to determine the barriers to timely disclosure of HIV serostatus for people living with HIV in Dar es Salaam, Tanzania, and identify what motivated disclosure.

Methods
A qualitative descriptive study using in-depth individual interviews was conducted with10 participants attending HIV care and treatment centers in Dar es Salaam. The participants were people living with HIV who had delayed disclosing their serostatus for more than one month after diagnosis. Data was analyzed using qualitative content analysis.

Results
Three categories emerged from the analysis: Barriers hindering timely disclosure, motivation for disclosure of serostatus, and consequences of delayed disclosure. Barriers to timely disclosure included denial of one’s status, the fear of stigmatization, fear of being separated or divorced, the need to protect loved ones, and lack of adequate knowledge about the disease. Reasons that motivated disclosure included gaining social support, preventing disease transmission and wanting to be at peace.

Conclusion
Timely disclosure is hindered by stigma because HIV is negatively perceived by the public. People living with HIV prefer not to disclose to avoid the negative consequences of disclosure, especially because of fear of being discriminated against and losing their social status, which plays a major role in social status in Tanzania.
Trust and adequate counseling from health care workers helps prompt disclosure.

Introduction
The surveillance of human salmonellosis in Belgium is dependent on the referral of human Salmonella isolates to the National Reference Center (NRC). Knowledge of current diagnostic practices and the coverage of the national Salmonella surveillance system are important to correctly interpret surveillance data and trends over time, to estimate the true burden of salmonellosis in Belgium, and to evaluate the appropriateness of implementing whole-genome sequencing (WGS) at this central level.

Methods
The coverage of the NRC was defined as the proportion of all diagnosed human Salmonella cases in Belgium reported to the NRC and was assessed for 2019 via a survey among all licensed Belgian medical laboratories in 2019, and for 2016–2020 via a capture-recapture study using the Sentinel Network of Laboratories (SNL) as the external source. In addition, the survey was used to assess the impact of the implementation of culture-independent diagnostic tests (CIDTs) at the level of peripheral laboratory sites, as a potential threat to national public health surveillance programs.

Results
The coverage of the NRC surveillance system was estimated to be 83% and 85%, based on the results of the survey and on the two-source capture-recapture study, respectively. Further, the results of the survey indicated a limited use of CIDTs by peripheral laboratories in 2019.

Conclusion
Given the high coverage and the limited impact of CIDTs on the referral of isolates, we may conclude that the NRC can confidently monitor the epidemiological situation and identify outbreaks throughout the country. These findings may guide the decision to implement WGS at the level of the NRC and may improve estimates of the true burden of salmonellosis in Belgium.

Vitamin D is a fat-soluble secosteroid that plays an important role in the human body. There are two main native forms – vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol). The regulation of calcium-phosphate metabolism and ensuring adequate bone remodeling are the most studied function of vitamin D. In recent years, researchers have found out the «extra-bone» effects of vitamin D and it allows us to be convinced of the great role of this compound. The participation of active forms of vitamin D in the processes of immunomodulation, anti-inflammatory, antimicrobial, antiproliferative effects and stimulation of cell differentiation are reflected in diseases of the maxillofacial region.In this article, we examined the main functions of vitamin D in the human body, the mechanisms of its action and influence on the occurrence and course of oral diseases. The discovery of the relationship between vitamin D deficiency and the processes of osseointegration, bone remodeling, the severity of chronic recurrent aphthous stomatitis, squamous cell carcinoma and periodontitis allow us to conclude that it is advisable to diagnose vitamin D deficiency in appropriate time and correction its serum level in dental patients.
