Authors: Zadok David , Smadja David , Weill Yishay , Abulafia Adi , Roditi Eduardo , Hanhart Joel
Published: April 2021

Aim

To describe a case of acute bilateral endothelial decompensation following prophylactic Nd:YAG laser iridotomy (LI) for occludable angles.

Background

Although regarded safe, LI can occasionally be a source of various ocular complications, including corneal endothelial damage. In the herein case, we describe the first case of acute bilateral endothelial decompensation after Nd:YAG LI.

Case description

A 63-year-old man was referred for consultation due to visual acuity deterioration in both eyes 2 weeks after undergoing an uneventful prophylactic LI for occludable angles. On examination, bilateral corneal edema with Descemet's membrane folds was observed. Direct corneal damage from the laser beam was not seen. Specular microscopy failed to count endothelial density. Anterior-segment optical coherence tomography (OCT), ultrasound biomicroscopy, and ocular biometry were performed. The patient was referred for bilateral endothelial keratoplasty.

Conclusion

Subacute endothelial dysfunction should be considered as a possible adverse event following Nd:YAG LI and patients should be advised accordingly.

Clinical relevance

Surgeons should be aware of the potentially devastating complication of bilateral corneal decompensation following routine Nd:YAG LI, even in patients without preexisting corneal injury. Patients should be advised accordingly.

Published: April 2021

The main aim of this study was to evaluate the real impact of the stress on employee performance level at Habib Bank Limited. As Stress was considered as emerging sensitive issue in this competitive and growth-oriented era, increasing expectations of employees lead to physiological and psychological stress problems that declined their performance level. In this study, Survey Questionnaire had been applied for this data collection. Data collected from 150 respondents of various branches of Habib Bank Limited was analyzed through the correlation test. The analysis concluded that employees experienced stress when the demands/expectations of the organization go beyond employee’s capability. Stress was the outcome of this role stressor: “role conflict”, “role ambiguity” as well as the “role overload”. Stress occurred when employees had no clarity about their task and duties and were overburdened with work. This research work might help the banking sector to know about effects and reasons of stress on employee’s performance level. Using these findings, banking sector can develop strategies to avoid stress for improving employee performance.

Prolactin exists in various forms including the monomeric biologically active form (23kDa) and a higher molecular weight form, bound most commonly to IgG, known as macroprolactin (>100kDa). Macroprolactin lacks biological activity and is one of the causes of false-positive results. In Russian Federation the most common method for macroprolactin determination is PEG precipitation test. We had conducted a retrospective analysis of 37 samples of patients with hyperprolactinemia (3 of them were males). The mean age was 30 [25;35] years. Prolactin level was measured by the immunoenzyme method with manual PEG precipitation and TRACE. The mean values found by the immunoenzyme method with manual PEG precipitation were 461,6 [375,0;821,2] mU/l, by TRACE - 449,9 [357,2;749,2] mU/l. The number of patients with normal prolactin levels was 30% (11) confirmed by two methods, high prolactin level at 46% (17). The prevalence of clinical symptoms of hyperprolactinemia was not differ depend the groups. The phenomenon of macroprolactinemia was registered in 32% (12) of patients. In 8 persons of this group normal prolactin level was revealed and in 4 patients hyperprolactinemia was found by TRACE. Measurements of prolactin levels by the TRACE method is useful for correct diagnosis in patients with equivocal results received by traditional method with PEG precipitation.

The purpose of this work was to show the effectiveness of the cytological method on a small number of observations, excluding all possible errors of the preanalytical stage. The paper presents several simple and easily reproducible algorithms for the cytological study of serous pleural effusions with small cellular content. On the example of 20 observations of the study of the cellular composition of serous exudates, a direct dependence of the research results on the preanalytical stage is shown. A complete study of effusion fluids in compliance with all stages of preanalytics and the use of modern methods of cytological diagnostics makes it possible to nullify the options for false-negative.
Dysregulatory processes of the cellular link of the immune system in the dynamics of common variable immunodeficiency
Authors: Sizyakina L. P. , Andreeva I. I. , Danilova D. I.
Published: April 2021

Common variable immunodeficiency (CVID) is a variant of primary immunodeficiency in which inhibition of antibody production is formed due to disorders of intercellular interaction affecting cellular elements of both innate and adaptive immune responses. A feature of CVID is the late start and variability of clinical minifestation. These arguments determine the purpose of the study: to identify the dynamics of changes in the cellular parameters of the adaptive and innate immune response depending on the duration and severity of the infectious manifestation of CVID. In this regard, a retrospective analysis of medical histories and dynamic observation of fifteen patients with CVID were carried out. Selection of specific parameters of cellular indices of factors of innate resistance and adaptive immunity was carried out on the basis of systemic-functional approach of immunodiagnostics. It is shown that in patients with CVID -mediated hypogammaglobulinemia and infectious phenotype of clinical manifestation, enhancement of quantitative and functional potentials of T-link effector cells of adaptive immunity is recorded against the background of reduction of number of regulatory T-helpers. With a more severe clinical course of the disease, the number of CD3+HLA DR + limphocytes is lower than with a more favorable version, there is a tendency to decrease the number of these cells, as well as the number of peripheral Treg with an increase in the length of the disease. Cellular components of innate immunity are characterized by a decrease in neutrophil activity, inhibition of antigen-presenting monocyte activity, the number and cytotoxicity of natural killers. At the same time, the tendency to decrease the cytolytic potential of NK with an increase in the length of illness and statistically significant differences depending on the severity of the manifestation of the infectious phenotype of CVID was recorded. The obtained results determine the importance of evaluating the cellular link of the immune system in patients with CVID, including as a prognostic criterion for the severity of the course.

Analysis of microsatellite instability (MSI) is a routine study in the diagnostics of solid malignancies. The standard for determining MSI is a pentaplex PCR panel of mononucleotide repeats: NR-21, NR-24, NR-27, BAT-25, BAT-26. The presence of MSI is established based on differences in the length of markers in the tumor tissue and in the control, but due to the quasimonomorphic nature of standard mononucleotide loci the use of a control sample is not necessary in the diagnosis of MSI-positive solid tumors. The significance of the MSI phenomenon in oncohematology has not been established. This paper presents the results of a study of MSI in B-cell lymphomas: follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), high-grade B-cell lymphoma (HGBL). We have shown that aberrations of mononucleotide markers occur in these diseases, but the nature of the changes does not correspond to the classical MSI in solid neoplasms. This fact requires further study of the pathogenesis of such genetic disorders. Due to the possibility of ambiguous interpretation of the results of the MSI study for previously uncharacterized diseases, strict compliance with the methodology of parallel analysis of the tumor tissue and the control sample is mandatory.

Abstract. Secondary organic aerosol (SOA) formation from mixtures of volatile precursors may be influenced by the molecular interactions of the products of the components of the mixture. Here, we report measurements of the volatility distribution of SOA formed from the photo-oxidation o-cresol, α-pinene and their mixtures, representative anthropogenic and biogenic precursors, in an atmospheric simulation chamber. The combination of two independent thermal techniques (thermal denuder and the Filter Inlet for Gases and Aerosols coupled to a high resolution time of flight chemical ionisation mass spectrometer) to measure the particle volatility, along with detailed gas and particle phase composition measurements provides links between the chemical composition of the mixture and the resultant SOA volatility. The products that were only present in the SOA of the mixture had higher O:C and lower volatility compared to those deriving from the individual precursors. This suggests that new product formation can reduce the volatility in mixtures. At the same time, some of the larger molecules with lower volatility produced in the single α-pinene and o-cresol system were not present in the mixture leading to an increase of the average volatility. These opposite effects resulted the volatility distribution of the SOA of the mixture to be between those of the individual precursors. For example, compounds with effective saturation concentration less or equal than 0.01 μg m−3 represented 28, 39 and 37 % of the SOA mass in the α-pinene, o-cresol and mixed precursor experiments, respectively. We further explore the sensitivity limitations of our technique to the reported results and we show that the particle volatility can be qualitatively assessed, while caution should be held when linking the chemical composition to the particle volatility. These results provide the first detailed observations of SOA particle volatility and composition in mixed anthropogenic and biogenic systems and provides an analytical context that can be used to explore particle volatility in chamber experiments.
Aerosol dynamics and dispersion of radioactive particles

Published: April 2021

Abstract. In the event of a failure of a nuclear power plant with release
of radioactive material into the atmosphere, dispersion modelling is used to understand how the released radioactivity is spread. For the dispersion of particles, Lagrangian particle dispersion models (LPDMs) are commonly used, in which model particles, representing the released material, are transported
through the atmosphere. These model particles are usually inert and undergo
only first-order processes such as dry deposition and simplified wet
deposition along the path through the atmosphere. Aerosol dynamic processes
including coagulation, condensational growth, chemical interactions,
formation of new particles and interaction with new aerosol sources are
usually neglected in such models. The objective of this study is to analyse
the impact of these advanced aerosol dynamic processes if they were to be
included in LPDM simulations for use in radioactive preparedness. In
this investigation, a fictitious failure of a nuclear power plant is studied for
three geographically and atmospherically different sites. The incident was
simulated with a Lagrangian single-trajectory box model with a new
simulation for each hour throughout a year to capture seasonal variability
of meteorology and variation in the ambient aerosol. (a) We conclude that modelling of wet deposition by incorporating an advanced cloud
parameterization is advisable, since it significantly influence simulated
levels of airborne and deposited activity including radioactive hotspots,
and (b) we show that inclusion of detailed ambient-aerosol dynamics can play
a large role in the model result in simulations that adopt a more detailed
representation of aerosol–cloud interactions. The results highlight a
potential necessity for implementation of more detailed representation of
general aerosol dynamic processes into LPDMs in order to cover the full
range of possible environmental characteristics that can apply during a release
of radionuclides into the atmosphere.
Methane in Zackenberg Valley, NE Greenland: Multidecadal growing season fluxes of a high Arctic tundra
Authors: Scheller Johan H. , Mastepanov Mikhail , Christiansen Hanne H. , Christensen Torben R.
Published: April 2021

Abstract. The carbon balance of high-latitude terrestrial ecosystems plays an essential role in the atmospheric concentration of trace gases, including carbon dioxide (CO2) and methane (CH4). Increasing levels of atmospheric methane have contributed to ~20 % of the observed global warming since the pre-industrial era. Rising temperatures in the Arctic are expected to promote the release of methane from Arctic ecosystems. Still, existing methane flux data collection efforts are sparse and highly scattered, and further attempts to assess the landscape fluxes over multiple years are needed.Here we use multiyear monitoring from automated flux chambers located on the fringe of a fen area in the center of Zackenberg Valley, northeast Greenland, from July and August (2006–2019). Direct measurements of methane fluxes showed high variability, with mean July–August fluxes ranging from 0.26 to 3.41 mg CH4 m−2 h−1. Methane fluxes based on manual chamber measurements are available from campaigns in 1997, 1999–2000, and in shorter periods from 2007–2013 and have been summarized in several published studies. Fluxes from the multiyear monitoring were combined with fluxes from the most common vegetation types, measured in 2007, and a detailed vegetation cover map to assess the methane flux on a landscape-scale and its variability over time.July–August landscape fluxes, estimated in the current study for the 2006–2019 period, were low compared to previous estimations. For the full study area covering the valley floor, the net methane source during these months was estimated as 0.06 to 0.83 mg CH4 m−2 h−1 and as 0.26 to 3.45 mg CH4 m−2 h−1 for the central fen-rich areas.A 2017–2018 erosion event indicates that some fen and grassland areas along the river in the center of the valley are becoming unstable following pronounced fluvial erosion and a prolonged period of permafrost warming. Although such physical disturbance in the landscape can disrupt the current ecosystem–atmosphere flux patterns, even pronounced future erosion along the river is unlikely to impact methane fluxes at a landscape-scale significantly. Instead, projected changes in future climate in the valley play a more critical role. The results show that multiyear landscape methane fluxes are highly variable at a landscape-scale and stress the need for long-term spatially distributed measurements in the Arctic.
Rattle dynamics of noncircular face gear under multifrequency parametric excitation
Authors: Liu Dawei , Lv Zhenzhen , Zhao Guohao
Published: April 2021

Abstract. A noncircular face gear (NFG) conjugated with a pinion is a
new type of face gear which can transmit variable velocity ratio and in which two time-varying excitations exist, namely the meshing stiffness excitation and instantaneous center excitation. Considering the tooth backlash, static transmission error and multifrequency parametric excitation, a nonlinear dynamic model of the NFG pair is presented. Based on the harmonic balance method and discrete Fourier transformation, a semi-analytic approach for the nonlinear dynamic model is given to analyze the dynamic behaviors of the NFG. Results demonstrate that, with increase in the eccentric ratio, input velocity and error amplitude, the NFG will undergo a non-rattle, unilateral rattle and bilateral rattle state in succession, and a jump phenomenon will appear in the dynamic responses when the rattle state of the gears is transformed from unilateral rattle to bilateral rattle.
Is YoutubeTM an accurate source of patient-information for awareness about periodontal diseases?
Authors: Güler Berceste , Özaltun Büşra
Published: April 2021

Objectives: Oral hygiene education and patient awareness are crucial for prevention and the sustainability of its treatment because of high prevalence of periodontal diseases. This study aimed to evaluate YouTube videos related to periodontal diseases and assess them comprehensively, reliability, and quality for non-professional internet users.Methods: YouTube search was performed using the three keywords: ‘periodontal disease’, ‘gingival disease,’ and ‘gum disease’. Video lengths, duration, numbers of total views, likes, dislikes, comments values were recorded. The interaction index, viewing rates and video power index (VPI) were calculated. Comprehensiveness tailor-made index was assessed for content, Global Quality Scale (GQS), and DISCERN scales were used for reliability and quality of videos.Results: A total of 210 videos were evaluated, and 79 videos were included in the study. While 69 of the videos are useful videos, 9 of them have misleading video content. VPI values were found 2.88±0.67 for useful videos and 1.78±0.66 for misleading videos. The mean GQS value of the videos has seen as 2.76±0.7. According to the DISCERN score, 41.8% of the videos show poor quality. The number of videos with comprehensiveness value (2) score is 44 and the number of videos (1) score is 35.Conclusions: YouTube videos may be used as an education source about periodontal disease for non-professional users; however, videos need to be improved in terms of content and quality. These and similar publications may be supported for the optimization of videos to be shared on YouTube with periodontal disease and oral hygiene education.

The Life Span of Large Historical Databases
Authors: Kok Jan
Published: April 2021

Large historical databases, although intended to last for a long time, can become obsolete for a variety of reasons. In this essay these reasons are explored and used for a 'health check' of the Historical Sample of the Netherlands (HSN). The HSN leaders are examined for their visionary qualities and their sense of ownership, and the database for its complementarity, versatility and consistency. The essay concludes that, despite challenges ahead, HSN is sound of mind and body.

The HSN and the Netherlands Indies: Challenge and Promise
Authors: Bosma Ulbe
Published: April 2021

In 2000 Kees Mandemakers and I started a project to trace the life courses of Dutch migrants to the Netherlands Indies. This article describes the process of data collection, the research questions and the project's main findings that have been published in various articles and a monograph. Two conclusions stand out: the first pertains to the heavily urban provenance of this migration and the second emphasizes the relatively educated and skilled background of colonial Dutch migration. This second finding contradicts earlier assumptions about the Dutch colonies as a place where undesirable elements were shovelled off. The current article further discusses findings of projects on Swiss and Luxembourger military migrations to the Netherlands Indies. An important difference between Dutch military migrants and those from other European countries regards the role of their service within a life course. While Dutch colonial military service was often the first step to make a career in colonial Indonesia, for Europeans from abroad it was rather a move of desperation as well as an attempt to earn some money that would enable them to start a business and a family in their country of birth. Their migration experience was rather a 'life cycle' migration. The article finally describes attempts to extend the HSN to the Dutch citizens born in the Netherlands Indies.
Maternal Life-Histories of Multiple Birth Mothers Compared to Singleton Only Mothers in 19th and Early 20th Century Netherlands
Authors: Ekamper Peter , Van Poppel Frans
Published: April 2021

Research on mothers of twins suggests they have a more robust phenotype compared to singleton only mothers. Historical demographic microdata can be of additional value in studying differences in reproductive behaviour and survival of their offspring between multiple birth mothers and singleton only mothers. However, the number of such studies in historical populations is limited. This study aims to explore the possibilities to study maternal life-histories of multiple birth mothers compared to singleton only mothers using microdata on 19th and early 20th century Netherlands from the HSN/LINKS database. In line with studies on other historical populations, our results confirm multiple birth mothers on average had their first birth at younger ages, their last birth at older ages, longer reproductive lifespans, shorter inter-birth intervals, and higher lifetime fertility than singleton only mothers.
Retirement, Home Care and the Importance of Gender

In recent decades elderly care policies in Sweden have been characterized by a marked shift from institutional care to home care. Previous research has highlighted how this has resulted in the elderly receiving care at a higher age and increased reliance on family and kin for providing care. Using register data for the entire Swedish population aged 65+ in 2016, we analyze how home care services in contemporary Sweden distribute regarding individual-level factors such as gender, health status, living arrangements, and closeness to kin. By far, the most critical determinants of receiving home care are age, health status, and whether the elderly are living alone or not. Although our results do not discard that access to kin have become more important, our results show that childlessness and geographical proximity to adult children play a minor role for differentials in the reception of home care. The main conduit for informal care instead takes the form of spousal support. Gender plays a role in how living arrangements influence the probability of receiving home care, where cohabiting women are significantly more likely to receive care than cohabiting men. We interpret this as a result of women, on average, being younger than their male partners and more easily adopting caregivers' roles. This gendered pattern is potentially explained by the persistence of more traditional gender roles prevailing in older cohorts.

La masculinidad como propaganda de autodefensa estatal en la sociedad patriarcal
Authors: Tarín Sanz Adrián
Published: April 2021

A pesar de los avances en la cuestión, son todavía numerosos los roles de género que persisten en nuestros imaginarios sociales occidentales. Algunas de estas atribuciones son estratégicamente potenciadas por los poderes hegemónicos tradicionales en sus apéndices de autodefensa: los cuerpos policiales y militares. Valores como la gallardía, la vigorosidad, la resolución o el patriotismo son patrimonio exclusivo del hombre cultural, por lo que para ser un buen soldado al servicio del ciudadano hay que comportarse como tal. La feminidad –cobardía, debilidad, homosexualidad o traición- queda ridiculizada hasta el extremo de identificar al enemigo con la mujer cultural. Los individuos y sus diversas orientaciones sexuales y de género deben adulterarse en favor de la salvaguarda del Estado.
