Published: January 2025

Background
Increasing observation and evidence suggest that the process of digitalization could have profound impact to the development of human mind and self, with potential mental health consequences. Self-differentiation is important in human identity and self-concept formation, which is believed to be involved in the process of digitalization.

Objective
This study aimed to investigate the relationship between digitalization and personal attributes in the actual selves in the physical and virtual worlds.

Methods
A community cohort of 397 participants aged 15 to 24 years old was recruited consecutively over about 3 months. Assessment was conducted upon the indicators of digitalization (smartphone use time, leisure online time, and age of first smartphone ownership), smartphone addiction, 14 selected personal attributes in the actual selves in the physical and virtual worlds, psychiatric symptomatology and personality traits. Euclidean distance analysis between the personal attributes in the actual selves in the physical and virtual worlds for the similarities of the 2 selves was performed in the analysis.

Results
The current primary findings are the negative correlations between the similarity of the personal attributes in the physical actual self and virtual actual self, and smartphone use time, smartphone addiction as well as anxiety symptomatology respectively (P<.05 to P<.01).

Conclusions
The current findings provide empirical evidence for the importance of maintaining a congruent self across the physical and virtual worlds, regulating smartphone use time, preventing smartphone addiction, and safeguarding mental health.
The Kinetics of Cystatin C and Serum Creatinine in AKI
Authors: Hooper Levi , Heung Michael , Kenes Michael , Stringer Kathleen A. , Mueller Bruce A. , Pai Manjunath P. 
Published: January 2025

Key Points

Modeling shows that serum cystatin C can detect AKI 6–48 hours earlier than serum creatinine, regardless of baseline kidney function.Absolute value diagnostic cutoffs are more effective than percentage-based thresholds for AKI detection across different CKD stages.

Background
AKI is a common condition affecting a significant portion of hospitalized and critically ill patients. Current AKI diagnosis relies on serum creatinine (sCr), which has several recognized limitations that affect the timely detection and response to AKI management. Serum cystatin C (sCys) has characteristics that can overcome the limitations of sCr, but head-to-head comparisons of these biomarkers are difficult to study prospectively. A quantitative assessment of the kinetics of sCys and sCr during AKI is necessary to support clinical workflow implementation for AKI diagnosis and management.

Methods
A quantitative systems pharmacology model was developed using Matrix Laboratories and Simbiology (The MathWorks, Natick, MA), to simulate the concentration–time profiles of sCr and sCys under varying degrees of AKI across a spectrum of baseline kidney function. The model incorporated parameters from existing literature and used a contemporary sCr and sCys GFR equation to assess the time to reach AKI diagnostic criteria for both biomarkers.

Results
The model demonstrated that sCys achieves steady-state concentration and meets AKI diagnostic thresholds significantly faster than sCr, with an advantage of 6–48 hours, depending on CKD stage. sCys exhibited greater sensitivity in detecting GFR reductions, with the ability to detect AKI within 12–24 hours after AKI, compared with 12–72 hours for sCr. The study also identified that for sCys, absolute value diagnostic cutoffs are more effective than percentage-based thresholds and can provide consistent detection across different CKD stages.

Conclusions
sCys has superior kinetics for early AKI detection compared with sCr, making it a valuable addition to AKI diagnostic protocols, particularly in high-risk populations. Daily monitoring of sCys in patients at risk of AKI would facilitate more timely detection and potentially improve clinical outcomes. Future research should focus on validating sCys diagnostic criteria and integrating it with other biomarkers to enhance AKI management.
Beyond Life Years Lost, Using Different Outcomes for Population Modelling in Tobacco Harm Reduction
Authors: Prasad Krishna , Hill Andrew , Fiebelkorn Stacy , Edward Lauren 
Published: January 2025

Summary
Evaluating the reduced-risk potential of novel tobacco and nicotine products, as compared to cigarettes, requires consideration not only of individual risk but also the impact on the population as a whole. Where the reduction in health risk for smokers who switch to the product instead of continuing to smoke, but also the product’s potential effects and rate of uptake among non-smokers must be taken into account.
Computational models have proven to be a valuable tool to enable evaluation of long-term population health effects, in the absence of epidemiological data. Most population health models projecting the health impact of novel tobacco and nicotine products have primarily focussed on potential population harm or benefit using premature ‘all cause’ mortality rates attributable to cigarette smoking as the key output indicator. This study expands on previous mortality projections for the introduction of tobacco heated products (THPs) in Japan, using an enhanced systems dynamics model including non-mortality outcomes. This enables investigation of additional projections for person-years lived with disabilities, tobacco related disease incidence, tobacco use prevalence and tobacco user behaviour, such as average smoker age, the number of years smoked and the age at which individuals ceased smoking. Disease specific projections are provided for the main smoking related diseases, lung cancer, CVD and COPD, and also for esophageal cancer and lower extremity peripheral arterial disease as examples of the potential wider application of this modelling approach.
Modelling estimates based on the available data, indicate that the introduction of THPs into the Japanese marketplace will reduce future smoking prevalence, smoking-related premature deaths and the burden of smoking related disabilities, compared to a scenario where THPs had not been introduced. The resulting projections demonstrate the ability to investigate population health impacts beyond all-cause mortality to provide further insight into the harm reduction potential of alternative nicotine products such as THPs.

Published: January 2025

One of the factors influencing the stress-strain state of the structure is the placement method of the columns and their step. The problem formulated in the article is to determine the design solution of the space grid structure with the least weight. The paper examines how the columns location, the number of support points, and the supports step affect the force values in the space grid structure rods and the supports (columns). The first variant of the model adopted a space grid structure supported in the corners of four columns. The second variant of the model adopted a space grid structure supported on two sides – six columns on each side. In the third variant, the structure is supported by 20 columns along the perimeter. It has been determined that the third method of supporting location is the most efficient.

The development of practical aspects of environmental safety requires taking into account the necessary parameters of the tech-nical condition of equipment, namely oil pipelines, including their operating conditions, climatic features of the regions, stand-ardized risk and safety parameters, and residual resource based on reliability and durability indicators.
On the basis of the electrochemical corrosion mathematical pipeline model in the insulating coating crack under the action of an aggressive electrolytic medium towards the pipeline metal, the dependence was obtained that allows to calculate the corrosion depth of the pipeline wall during the work of macro-galvanic corrosion couples in the conditions of stable and periodic stay of the aggressive solution in the damaged zone. The advantage of this model is the ability to predict the development of corrosion over time regardless of the corrosive electrolyte chemical composition, the possibility of obtaining necessary design parameters for operated structures. The developed dependencies of the pipeline section сorrosion depth make it possible to plan rationally the repair work, to predict the real terms of the structure work, to review the operation mode, etc. The obtained results allow us to more reliably evaluate the bearing capacity of structures that operate in conditions of aggressive medium with cracks
