Providing Support for Use of Digital Mental Health Interventions: A Systematic Meta-Review (Preprint)
Authors: Werntz Alexandra , Amado Selen , Jasman Megyn , Ervin Ariel , Rhodes Jean E.
Published: September 2022

BACKGROUND

Human support has been increasingly studied as a means of improving outcomes of digital mental health interventions (DMHIs). Although a growing number of studies and meta-analyses have investigated the effects of human support for DMHIs on mental health outcomes, systematic empirical evidence for its effectiveness across mental health domains remains scant.

OBJECTIVE

The goal of this study was to summarize the effects of human support and no support for DMHI use across various outcome domains, participant samples, and support providers.

METHODS

A systematic meta-review of meta-analyses was conducted, comparing the effects of human support to no support for DMHI use, with the goal of summarizing across various outcome domains, participant samples, and support providers. Only meta-analyses that compared effect size of human support with that of no support were included.

RESULTS

Results from 31 meta-analyses representing 505 unique primary studies were reported. The quality of the evidence for effectiveness of human support was assessed using the AMSTAR 2 review system. The meta-analyses reported 45 effect sizes; almost half (48.89%, N=22) showed that human-supported interventions were significantly more effective than unsupported interventions. Only four (8.89%) effect sizes showed that unsupported were significantly more effective. Evidence emerged for stronger effects of human support for individuals with greater symptom severity.

CONCLUSIONS

There was considerable heterogeneity across meta-analyses in the level of detail regarding the nature of the interventions, population served, and support delivered. The results highlight the potential of human support in improving the effects of DMHIs as a way of increasing access to evidence-based mental health tools. We conclude with suggestions for future research.
Building LABDRIVE, a Petabyte Scale, OAIS/ISO 16363 Conformant, Environmentally Sustainable Archive, Tested by Large Scientific Organisations to Preserve their Raw and Processed Data, Software and Documents
Authors: Giaretta David Leslie , Redondo Teo
Published: September 2022

Vast amounts of scientific, cultural, social, business and government, and other, information is being created every day. There are billions of objects, in a multitude of formats, semantics and associated software. Much, perhaps the majority, of this information is transitory but there is still an immense amount which should be preserved for the medium and long term â€“ perhaps even indefinitely.
Preservation requires that the information continues to be usable, not simply to be printed or displayed. Of course, the digital objects (the bits) must be preserved, as must the â€œmetadataâ€ which enables the bits to the understood which includes the software.
Before LABDRIVE no system could adequately preserve such information, especially in such gigantic volume and variety. 
In this paper we describe the development of LABDRIVE and its ability to preserve tens or hundreds of petabytes in a way which is conformant to the OAIS Reference Model and capable of being ISO 16363 certified.
The XP Stabiliser Formalism: a Generalisation of the Pauli Stabiliser Formalism with Arbitrary Phases
Authors: Webster Mark A. , Brown Benjamin J. , Bartlett Stephen D.
Published: September 2022

We propose an extension to the Pauli stabiliser formalism that includes fractional 2π/N rotations around the Z axis for some integer N. The resulting generalised stabiliser formalism – denoted the XP stabiliser formalism – allows for a wider range of states and codespaces to be represented. We describe the states which arise in the formalism, and demonstrate an equivalence between XP stabiliser states and 'weighted hypergraph states' – a generalisation of both hypergraph and weighted graph states. Given an arbitrary set of XP operators, we present algorithms for determining the codespace and logical operators for an XP code. Finally, we consider whether measurements of XP operators on XP codes can be classically simulated.
Transitions in Entanglement Complexity in Random Circuits
Authors: True Sarah , Hamma Alioscia
Published: September 2022

Entanglement is the defining characteristic of quantum mechanics. Bipartite entanglement is characterized by the von Neumann entropy. Entanglement is not just described by a number, however; it is also characterized by its level of complexity. The complexity of entanglement is at the root of the onset of quantum chaos, universal distribution of entanglement spectrum statistics, hardness of a disentangling algorithm and of the quantum machine learning of an unknown random circuit, and universal temporal entanglement fluctuations. In this paper, we numerically show how a crossover from a simple pattern of entanglement to a universal, complex pattern can be driven by doping a random Clifford circuit with T gates. This work shows that quantum complexity and complex entanglement stem from the conjunction of entanglement and non-stabilizer resources, also known as magic.
Cyber Security, Cyber Threats, Implications and Future Perspectives: A Review
Authors: Ghelani Diptiben
Published: September 2022

There is a wealth of information security guidance available in academic and practitioner literature. Although other tactics such as deterrence, deception, detection, and reaction are possible, most of the research focuses on how to prevent security threats using technological countermeasures. The findings of a qualitative study conducted in Korea to determine how businesses use security techniques to protect their information systems are presented in this article. The results show a deeply ingrained preventative mindset, driven by a desire to ensure the availability of technology and services and a general lack of awareness of enterprise security concerns. While other tactics were evident, they were also preventative measures. The article lays out a research agenda for deploying multiple strategies across an enterprise, focusing on how to combine, balance, and optimize systems. This research looked at various topics, including information security and areas where security strategy is likely to be discussed, such as military sources. There are nine security strategies identified. A qualitative focus group approach is used to determine how these security strategies are used in organizations. In focus groups, security managers from eight organizations were asked to discuss their organizations’ security strategies. According to the findings, many organizations use a preventive approach to keep technology services available. Some of the other identified methods were used to support the prevention strategy on an operational level.
The Interplay Between Diabetes, Cardiovascular Disease, and Kidney Disease
Authors: Usman Muhammad Shariq , Khan Muhammad Shahzeb , Butler Javed
Published: September 2022

The Global Burden of Disease Study estimates that there are currently 476 million patients with diabetes worldwide, the large majority of whom suffer from type 2 diabetes. The metabolic system is closely interrelated with the cardiac and renal systems, and these three systems share a symbiotic relationship that helps maintain homeostasis. The heart is one of the most metabolically demanding organs and is sensitive to changes in energy and volume status. Thus, it relies on the liver, pancreas, and fat for optimal energy metabolism and on the kidneys for volume maintenance. Similarly, the kidneys rely on the heart for adequate perfusion and on the metabolic system for the appropriate hormonal milieu, both of which are necessary to maintain their function.

Objective: Hyperglycemia can increase urinary zinc excretion. We evaluated  the association of higher urinary zinc with newly diagnosis of incident type 2 diabetes (T2DM incidence) in adult populations with a high burden of T2DM from Arizona, Oklahoma, North Dakota and South Dakota. We also assessed the cross-sectional association of urinary zinc levels with prevalent prediabetes.

Research Design and Methods: We included 1,339 adults free of T2DM at baseline (1989-1991) followed through 1998-1999 in the Strong Heart Study (SHS) and in 1,905 family members of SHS participants followed as part of the Strong Heart Family Study (SHFS) through 2006-2009. 

Results: T2DM incidence was 14.7% (mean follow-up 6.6 years) in the SHS and 13.5% (mean follow-up 5.6 years) in the SHFS. After adjustment for sex, site, education, smoking status, BMI and estimated glomerular filtration rate, the hazard ratio (95%CI) of T2DM comparing 75th vs. 25th percentiles of urinary zinc distribution was 1.21 (1.08, 1.36) in the SHS and 1.12 (0.96, 1.31) in the SHFS. These associations were attenuated but significant in the SHS after adjustment for HOMA-IR score. Excluding participants with prediabetes at baseline, urinary zinc remained significantly associated with T2DM in the SHS. In cross-sectional analyses, prediabetes was associated with higher urinary zinc levels. 

Conclusions: Urinary zinc levels were associated with T2DM incidence and prediabetes prevalence even after adjustment for HOMA-IR in populations with a high burden of T2DM. These results highlight the importance of zinc metabolism in diabetes development. 
Wear and Color Stability of Preheated Bulk-fill and Conventional Resin Composites
Authors: Abdulmajeed AA , Suliman AA , Selivany BJ , Altitinchi A , Sulaiman TA
Published: September 2022

Objectives

Bulk-fill resin composite is commonly used in direct restorations. It is recommended that the high-viscosity version of these materials be preheated to improve flowability and adaptability. It is unknown what effects preheating (PH) might have on the wear resistance and color stability of these resin composites. This study compared the wear and color stability of high-viscosity bulk-fill and conventional resin composites with and without PH, using the CIEDE2000 formula.

Methods and Materials

Thirty-two disc-shaped specimens (n=16, 10×3 mm) were prepared with Filtek One Bulk Fill Restorative (FOBFR; 3M ESPE) and Filtek Supreme Ultra (FSU, 3M ESPE) to determine wear. Each group was divided into subgroups based on preparation conditions, that is, PH and room temperature (RT) (n=8). Thermomechanical fatigue was applied to specimens, and volumetric material loss was calculated using a laser scanner (LAS-20, SD Mechatronik, Feldkirchen-Westerham, Germany) and three-dimensional imaging software (Geomagic, 3D Systems, Rock Hill, SC, USA). An additional 124 disc-shaped specimens (n=64, 10×1 mm) were prepared with FOBFR and FSU, and subgroups were formed based on preparation conditions (PH and RT, n=32). Specimens were aged for 14 days in coffee, grape juice, distilled water, and thermocycling (20,000 cycles, 5°C–55°C). To determine color change, the lightness (L), chroma (C), and hue (H) values were measured at baseline and after 14 days using the CIEDE2000 formula. All data were statistically analyzed, and a 95% significance level was set.

Results

In both the PH and RT groups, FSU exhibited greater wear than FOBFR (p<0.05). Both materials were subjected to increased wear as a result of PH. After aging, a significant difference in color change was observed (p<0.05) when controlling for time and resin composite type, except for deionized water and thermocycling (p>0.05). PH had no effect on the color stability of the resin composite at any time (p<0.05).

Conclusion

The high-viscosity bulk-fill resin composite displayed superior wear resistance and similar color stability compared with its conventional counterpart. PH resin composite may increase its susceptibility to wear and has no effect on its color stability.
Mycotoxins and Mycotoxigenic Fungi in Ready to Eat Spices and their Prevention
Authors: Hashem Mohamed
Published: September 2022

The study aimed at monitoring the effect of long storage of the daily-used spices under varying humidity on the development of mycotoxins and their producing fungi. The spices samples were analyzed for mycotoxins and their potential producing fungi. The results showed that Aspergillus, Eurotium, Fusarium, and Penicillium were the most frequent genera on spices. Aspergillus flavus, A. niger, A. niveus, Eurotium chevalieri, Fusarium oxysporum, F. verticillioides, Penicillium cyclopium, and P. waksmanii were detected as potential mycotoxin-producing fungi. The results exhibited the contamination of spices with aflatoxin B1 and G1, zearalenone, citrinin, and sterigmatocystin in high concentration (66.45µg/Kg, 12.64µg/Kg, 0.064µg/Kg, 0.065µg/Kg, and 0.065µg/Kg, respectively). The results proved that time were a key factor in development of fungi and their mycotoxins. After six months of storage under high RH% (75-80%), the total count of fungi was increased dramatically in some spices like as dill (9.1 x 104 CFU/ g) and sumac (23.16 x 102 CFU/g). However, in the other spices, storage under moderate (50-55%) or natural humidity (10-45%) encouraged the development of fungi more than under high humidity %. The study recommends consumers to use dry fresh spices and not store them for more than two months.

Published: September 2022

DIY's coastal area is one of DIY's development priorities by establishing the site as an economic corridor that impacts physical development, such as settlements in the coastal area of DIY. This study aims to analyze the distribution and density of settlements. The method used in research is a quantitative descriptive and Geography Information System approach. The analysis used in this study is Nearest Neighbour Analysis (NNA) and Kernel Density Analysis with an analysis tool in ArcGIS 10.5. The results of the NNA show that the three districts located on the coast of DIY have the same distribution pattern characteristics, namely, the clustered pattern, which means the NNA index value is <1 or the T value ranges from 0-0.80. The results of the kernel density analysis show that the most significant density is found in Kulon Progo Regency, precisely in Wates District, and Bantul Regency, precisely in Srandakan District. At the same time, for Gunung Kidul Regency, it is less significant, and the density is only centered on one density point. Several factors cause settlement density, including physical factors (topography, slope, soil type, and clean water sources), accessibility (proximity to transportation routes and proximity to the city center), availability of facilities and infrastructure (electricity network, educational facilities, and health), and environmental factors (natural and human resources).Keywords: Settlements, Coastal, NNA, Kernel Density

A non-profit entity faces multiple accountabilities as the main stakeholders are wider. Reporting is arguably one of the mechanisms to show the discharge of accountability. This paper identifies the reason for the reporting practices of foundations – non-profit entities. Using the ‘accountability reporting’ framework (Ebrahim, 2003a) the reporting practices were viewed from the legal, bureaucratic, and social perspectives. Four foundations with different legal structures were examined through semi-structured interviews, supported by document reviews. The study found that the reporting practices were guided by the perceived importance of the main stakeholder. In the absence of dedicated accounting standards, the reporting practices follow who the foundations perceive they should be accountable to the most. Different foundation undertook reporting practices differently. The study indicates the importance of being sensitised towards the organisational and legal structure of foundations. As NPO – including foundation is established to assist beneficiaries, this main mission should always be privileged despite different organisational/legal structures. Future research may be undertaken to itemise the reporting difference among these foundations in order to identify the trend and relationship of accountability and reporting choice.

Firms have tendencies to manipulate their financial statements when it is at risk of bankruptcy due to financial distress. Based on the Fraud Diamond Theory, there are four factors that motivate firms to perpetrate fraud, namely pressure, opportunity, rationalization and capability. Therefore, this study investigated the effect of these fraud diamond factors on the likelihood of fraudulent financial reporting among financially distressed firms in Malaysia. In addition, this study investigated whether the new amendment of code of corporate governance on risk management practices can mitigate the effect of these four factors on the likelihood of fraudulent financial reporting. Based on a sample of 53 financially distressed firms from 2014 until 2019, this study found that two fraud diamond factors which are pressure and capability significantly influenced firms’ financial distress and thus influenced the likelihood of fraud. The study found that risk management can reduce pressure and thus reduce the likelihood of fraud of financially distressed firms. Meanwhile, distressed firms change directors to replace with competent ones. Nevertheless, the study found that distressed firms may increase their risk disclosures to cover up their distress by changing directors. This study investigated the prevalence of fraud among distressed firms. Furthermore, it extends the literature of risk management among distressed firms.

Published: September 2022

This study explored the perspectives of reformers on public financial management (PFM) reforms in Ghana. This research, an exploratory qualitative study focused on unearthing the perspectives of reformers in PFM reforms. Reformers, as identified in this study were individuals in the PFM landscape who were middle level civil servants implementing reforms formulated by politicians and top bureaucrats. They try to enhance the management of public finances in the country by implementing the reforms. Participants were made up of 22 individuals involved in PFM reforms, purposively selected for one-on-one interviews from the civil service in Ghana. Another eight individuals participated in a focus group discussion. Public financial management reforms have been ongoing in Ghana for over two decades now. Findings showed that respondents believed in the reforms they participated in and reported levels of enthusiasm and dedication to achieving the aims of the reforms. The findings from this study indicated that the success of the roll out of PFM reforms depended not only on the known success factors such as the implementation arrangements and leadership but also on the reformers’ perspectives and their power of influence on the reforms amongst others.

This study aimed to fill the gap by measuring and examining the level of GPG for local governments in Indonesia. The study used a multidimensional index by incorporating information from the Indonesia Governance Index (IGI) principles indicators, the Evaluation of local government performance reports, the annual reports of local governments financial statement and the Central Bureau of Statistics from 2015 to 2017. The Two-staged Factor Analysis was employed for weights assignment. The results are presented based on comprehensive scores and ranks for five district and city levels of the local governments which had have the highest and lowest values for each GPG principle and overall GPG index. The findings showed that there was evidence of an increasing trend on the implementation of GPG principles in the local governments. There were also evidence on the lack of information regarding which indicators needed to be improved, due to lack of awareness among the local governments on importance of quality application of the GPG principles in the government system. It implies that the central government focused on performance evaluations, rather than implementation of GPG in local governments. The findings suggest that it is useful for the local governments to measure the level of good public governance using the multidimensional GPG index rather than using a single dimension.

Operational risk management practice varies from one organization to another. There is no consistency in its implementation. This has caused misinterpretation, half-hearted implementation which eventually, denies the full function of its capabilities to support a business operation. Previous studies have provided limited exposure in finding on the best practice of operational risk management implementation. To fill the gap, this study aimed to uncover and explore how operational risk management is institutionalized within an organization and the best practice from a primary GLC in Malaysia. An extended case study approach by Burawoy (1998) was adopted. The primary data from 42 semi-structured interviews were analyzed using thematic analysis. The study found seven processual stages which the case company underwent to institutionalize risk management and regarded as the best practice of operational risk management implementation that supports business operations. Namely, strong leadership and obtaining external consultancy, setting the apparatus and assignment of tasks to the person in charge, risk framework, risk diagnostics, monitor and measure, developing and nurture a risk management culture, and consistent risk management enforcement and monitoring. These are regarded as a best practice by similar organizations in its sector. Keywords: case study, institutionalization, operational-risk-management

Auditors’ ethical behavior has become a concern globally with the continued occurrence of financial scandals. As a result, regulators, researchers and other stakeholders are focusing on auditors’ ethical behaviour, auditor independence and professional skepticism. As there are limited studies on the issue, the purpose of this study was is to examine the influence of professional skepticism and independence on the ethical behaviour of Indonesian auditors based on Rest’s model within the context of certain material audit adjustments to be recorded by an audit client. This study was also intended to examine the mediation effect of state professional skepticism on the relationship between auditor’s independence threat and auditors’ ethical decision making. This study adopted the experiment approach by utilizing case scenarios. There were 121 auditors from the Big 10 firm in Indonesia as participants of this study. This study found that despite auditors not recognizing the ethical issues due to independence threat, they still can act ethically. Further, state professional skepticism did not affect ethical decision making of auditors. Keywords: ethical decision making, professional skepticism, auditor independence

Negative effects of long-lasting media attention to public issues on recipients: Conceptualizing issue fatigue
Authors: Gurr Gwendolin , Schumann Christina , Metag Julia
Published: September 2022

A significant amount of political communication research is grounded in the dynamics of the media’s and the public’s attention to public issues, assuming that the news media draw the public’s attention to issues, thereby fostering an informed and participating citizenry. However, there is evidence from several countries that this mechanism is disrupted for issues with high shares of news coverage during a period. Against this background, this article scrutinizes the idea that recipients become fatigued from these issues in the news. Having transferred findings on overexposure from other media stimuli to the news environment, issue fatigue is defined as a negative cognitive and affective state consisting of decreasing issue-specific information processing involvement, perceived information overload, and increasing boredom, annoyance, and anger toward an issue. Issue fatigue can lead to the avoidance of information about the issue, thus serving as a new explanatory approach to avoidance of media information at an issue level. Further consequences, causes, and the development of issue fatigue are discussed.
Whole blood and plasma taurine reference intervals in adult Cavalier King Charles Spaniels and correlations between taurine concentration, diet and mitral valve disease
Authors: Wesselowski Sonya , Blake Amanda B. , Gordon Sonya G. , Suchodolski Jan S. , Steiner Joerg M.
Published: September 2022

OBJECTIVE

To determine breed-specific reference intervals for whole blood (WB) and plasma taurine concentrations in adult, overtly healthy Cavalier King Charles Spaniels (CKCSs) and determine whether taurine concentrations differ across preclinical myxomatous mitral valve disease (MMVD) stages or between CKCSs eating diets that meet World Small Animal Veterinary Association (WSAVA) nutritional guidelines versus other diets.

ANIMALS

200 privately owned CKCSs.

PROCEDURES

Clinically healthy adult CKCSs were recruited prospectively. Diet and supplement history was collected. Dogs were staged by echocardiography using MMVD consensus guidelines. Taurine concentrations were measured in deproteinized lithium heparin WB and plasma samples with the postcolumn ninhydrin derivatization method on a dedicated amino acid analyzer.

RESULTS

There were 12 stage A (6%), 150 stage B1 (75%), and 38 stage B2 (19%) CKCSs. Seventy-eight dogs (39%) were reported by their owners to be eating diets meeting WSAVA nutritional guidelines; 116 (58%) were not. Taurine concentrations in plasma (P = .444) and WB (P = .073) were not significantly different across MMVD stages or between CKCSs eating diets meeting WSAVA nutritional guidelines versus other diets (P = .345 and P = .527, respectively). Reference intervals for WB taurine (152 to 373 µM) and plasma taurine (51 to 217 µM) concentrations in CKCSs were generated.

CLINICAL RELEVANCE

In CKCSs, taurine concentrations do not differ significantly based on preclinical MMVD stage, nor do they differ significantly based on consumption of a diet that does or does not meet WSAVA nutritional guidelines.
Semantic-Based Dynamic Service Adaptation in Context-Aware Mobile Cloud Learning
Authors: Muhamad S. , Admodisastro N. , Osman H. , Ali N. M.
Published: September 2022

Self-adaptable system concerns on service adaptation whenever errors persist within the system. Changes in contextual information such as networks or sensors will affect the system’s effectiveness because the service adaptation process is not comprehensively handled in those contexts. Besides, the correctness to get the most equivalence services to be substituted is limitedly being addressed from previous works. A dynamic service adaptation framework is introduced to monitor and run a reasoning control to solve these issues. Hence, this paper presents a case study to proof the dynamic service adaptation framework that leverages on semantic-based approach in a context-aware environment. The evaluation of the case study resulted in a significant difference for the effectiveness at a 95% confidence level, which can be interpreted to confirm that the framework is promising to be used in operating dynamic adaptation process in a pervasive environment.

This study presents data on regular health monitoring of fish in the Aquatika – Freshwater Aquarium Karlovac between October 2016 and December 2019. The Aquatika Aquarium houses 85 different freshwater fish species, 31 of which are endemic in Croatia. The study included an evaluation of the results of the aquarium health monitoring programme. It determined the most common fish diseases in the aquarium (at the species and individual levels) and determined whether endemic or non-endemic freshwater fish are more susceptible to diseases and disorders. The regular health monitoring programme revealed different diseases and disorders in endemic and non-endemic fish. During the monitoring, 3104 fish specimens were analysed. The most frequent disease was ichthyophthiriasis which occurred at a similar frequency in endemic and non-endemic fish species. The results proved to be valuable for the evaluation of risks and measures to minimise the risk of the introduction and spread of pathogens in the aquarium. Preventive fish medicine is extremely important for effective aquarium management. A comprehensive health monitoring programme, including quarantine systems, control of feed and environmental parameters, along with regular fish observation, are critical for the early detection of fish diseases.

Industrial agriculture contributes to greenhouse gas emissions and is degrading agricultural land. To reduce the impact of agriculture on the environment, a transition to sustainable agriculture is necessary. The article assesses the prospects for sustainable agriculture in Russia. It examines three models for their applicability to Russia: food sovereignty, community supported agriculture, and business as usual.
Active-clamped flyback DC-DC converter in an 800V application: Design notes and control aspects
Authors: Vračar Darko , Pejović Predrag
Published: September 2022

This paper presents findings for active-clamped flyback (ACF) DC-DC converter 57 W used as an auxiliary power-supply of a wireless inductive-charging system 800 V. Measurements of magnetizing and leakage inductances for three transformers demonstrated how big differences between them could be depending on chosen vendor. Comparison of simulated and measured Bode plots showed that, even when those plots were not matched, one could design a compensator that ensures stable operation. Evaluation of cross-regulation when output with low power (9.62 % of total) was regulated showed that such approach was feasible too. The switching frequency vs output-power and drain-source voltage of switch vs output-power graphs are presented for the first time. Comparison of bandwidth, phase-margin and gain-margin vsinput-power, between the ACF and conventional flyback converter were discussed too. Those quantities were changeable with load and input-voltage as expected. The conventional flyback converter in DCM has higher bandwidth than the ACF which resulted in lower phase- and gain-margins. That showed that it cannot have the same compensator as an ACF.
Model predictive control for distributed MPPT algorithm of cascaded H-bridge multilevel grid-connected PV inverters

Published: September 2022

This paper concentrates on an algorithm with model predictive control for current and distributed MPPT for cascaded H-bridge multilevel photovoltaic (PV) inverter applications. In conventional method, in each sampling period, a discrete-time model is employed to predict the current future values for all vectors of voltage. The voltage vector will be approved if it minimizes the cost function. Because multilevel inverter has so many available voltage vectors, there is a large quantity of calculations, hence it makes difficult in implementing the normal control method. A varied control strategy that extensively decreases the calculations volume and eliminating common-mode voltage is proposed. To raise the PV modules performance and enlarge the systems power, a distributed maximum power point tracking (MPPT) control scheme for each phase of multilevel inverter is offered, that allows its DC-link voltage to be regulated separately. The recommended approach is double-checked by using a model simulated in MATLAB-Simulink software.

Published: September 2022

Background: BNT162b2 is a widely used mRNA COVID-19 vaccine for which 8.2% of participants above the age of 56 years have reported diarrhea as an adverse event. This case report highlights the possibility of eosinophilic colitis in post-vaccination diarrhea.

Case report: A 72-year-old male patient presented with generalized colicky abdominal pain and acute diarrhea after receiving the first dose of the BNT162b2 vaccine. Laboratory examination revealed peripheral blood eosinophilia with cecal and ascending colon mucosal eosinophilia with 100–130 cells/HPF and eosinophilic cryptitis. The patient’s symptoms and eosinophilia resolved spontaneously and did not recur after the second dose of vaccination. More research is needed to confirm eosinophilic colitis as a possible vaccine adverse reaction.

Published: September 2022

The eye tracking technique is increasingly used in the context of examining the method of processing visual information from instruments and displays located in the cockpit of an airplane. An important aspect is monitoring the pilot’s visual behavior in the most difficult phase of the flight, which is the landing of the plane. Six people participated in the research, divided into three groups according to their experience. The subjects performed three landing approaches in various weather conditions. During the study, the visual behavior of the participants was recorded using the Pupil Invisible eye tracker. Based on the analysis of heatmaps and areas of interest, differences in the distribution and number of fixations in the visual field between pilots with different aviation experience were shown.

Published: September 2022

Since Poland’s accession to the European Union in 2004, a steady increase in transaction prices of agricultural property has been observed. Also in other countries, mainly in Eastern and Central Europe, there has been an ongoing increase in the prices of agricultural land. The situation on the agricultural land market is influenced not only by the market mechanisms, but also by the political decisions, including restrictions in the turnover of land properties. The purpose of the study is to analyze the agricultural land market in Poland and to determine the relationship of average land prices for housing, service and industrial purposes against the average prices of agricultural land in 2004-2019. In the course of the study, price changes on the discussed market were assessed, and forecasts and simulations concerning the prices of agricultural properties and land intended for selected investment purposes were prepared. It was established that the increase in agricultural property prices over the recent dozen or so years is inadequate to the increase in the average gross salary in Poland and the average income from work at individual farms. However, the increase in prices is almost parallel to the increase in average transaction prices of property intended for housing purposes.

Congenital granular cell tumor is an uncommon benign oral lesion of uncertain histogenesis that affects the alveolar ridge region of newborns. The present study aims to report an unusual congenital granular cell tumor case, emphasizing clinical, morphological, and immunohistochemical aspects. A 10-day-old newborn patient attended the stomatology service with a nodular pedunculated lesion of normal color located in the anterior region of the superior alveolar ridge. Thus, the diagnostic hypothesis was congenital epulis, and an excisional biopsy was performed. Histopathological analysis revealed features consistent with the diagnosis of congenital granular cell tumor. In addition, we performed immunohistochemical staining for vimentin, Ki-67, and S100. The patient has been under follow-up with no clinical signs of recurrence. Due to its rarity, the analysis of congenital granular cell tumor’s clinicopathological characteristics enables an adequate diagnosis and treatment.
