Evaluation of Blood Lactate among Different Player Roles: A Pilot Study
on Competitive Young Male Soccer Players
Authors: Arcone Rosaria , Montesano Pietro , Di Silvestro Maurizio , D'Errico Antonio , Meccariello Rosaria , Mazzeo Filomena 
Published: February 2024

Background:
Soccer match requires anaerobic and aerobic energetic metabolism.
The aim of this pilot study was to investigate the changes in blood lactate concentration in
young male soccer players in different playing roles at different time points after the soccer
match.

Methods:
Following an initial screening of 134 young soccer athletes, 8 male athletes (average
age of 15.5 ± 5 SD) were chosen for their characteristics similar to those of competitive athletes.
Players were categorized as goalkeeper, central defender, central midfielder, and forward. Blood
lactate concentrations were determined using a portable device at different times (10 min, 5 and
16 h) after the soccer match by a maximum effort test on a treadmill. The data were analyzed by
one-way analysis of variance ANOVA, followed by Bonferroni’s post-hoc test.

Results:
The following results (mean ± SD) were obtained: VO2max (%) 60.33 ± 3.10; blood
lactate (mM) end match (10 min) 2.17 ± 0.78, post-match-early (after 5 h) 2.2 ± 0.42, postmatch-
late (16 h) 3.2 ± 0.84. ANOVA analysis indicated that the blood LA concentrations at
end-match (10 min) and post-match-early (5 h) were statistically significative lower than those
determined at post-match-late (16 h) (p < 0.05).

Conclusion:
These results suggest that aerobic mechanisms can also use LA as an energy
source, contributing to the reduction of its blood concentration. This effect can be due to reduced
maximal work during a soccer match and to the LA removal during exercise at reduced
intensity. These data can provide indications for planning suitable training strategies for young
male soccer players.
State of the Art on the Contributions and Use of Geographic Information Systems (GIS) in Epidemiology in Morocco
Authors: Haisoufi Driss , Bouaiti El arbi 
Published: February 2024

Background
The Geographic Information System (GIS) plays a significant role in the healthcare information system. The use of GIS as an epidemiological research tool is very little known in Morocco. According to the Moroccan Ministry of Health's Health Plan for 2025, axis 23 aims to complete the deployment of the decision support information system through the implementation of the geographic information system with the goal of improving governance and optimizing resource allocation. This creates constraints in achieving the design of an appropriate GIS for modeling pathologies using remote sensing and spatial statistical methods. The current work aims to understand GIS and its applications in epidemiology, with a focus on the state of scientific knowledge related to GIS in epidemiological research.

Methods
A state-of-the-art review of the various uses of GIS in epidemiological research was conducted using several university databases, such as PubMed and Scopus, recent articles, and certain reference books, focusing on the following keywords: “utilization,” “GIS,” and “epidemiology,” as well as their synonyms identified by MeSH.

Results
The majority of GIS research applied to epidemiology primarily involves making observations using GIS, which are then incorporated into action plans to promote population health. Therefore, it is important to break down the aspects of GIS (Geographic Information System) usage in epidemiology into four components. These include epidemiological surveillance, determining primary healthcare needs, healthcare planning, and healthcare quality.

Conclusion
These results clearly demonstrate the significant contribution of GIS to the improvement of public health. However, there is a need for positive action regarding the integration of this system, especially in developing countries.
Research on Power Angle Characteristics of One-Machine Infinite-Bus
Power Systems of Mixed Gauss and Poisson Stochastic Excitation
Authors: Li Lijuan , Li Yuange , Xiao Chuang , Zheng Xinhui , Li Qing 
Published: February 2024

Background:
A high percentage of renewable energy and a high percentage of power
electronic devices are connected to the power system, which leads to the diversification and
complexity of stochastic excitation, and the traditional single-excitation stochastic model is no
longer applicable.

Objective:
The study aimed to solve the problem that the high proportion of renewable energy
and the high proportion of power electronic equipment are connected to the power system, which
leads to the diversification and complexity of stochastic excitation and makes the traditional stochastic
model of single excitation no longer applicable.

Methods:
Firstly, stochastic differential equations for power systems have been modelled with
mixed Gaussian white noise and Poisson white noise excitation. Secondly, the Milstein-Euler
predictor-corrector method has been developed to solve the stochastic differential equation model
of the power system. Finally, the influence of Gauss white noise and Poisson white noise on
the power system stability under different excitation intensities has been analyzed. The rationality
and correctness of the model have been verified by the simulation of a one-machine infinitebus
(OMIB) system.

Results:
The stochastic differential equation model of a power system with Gauss white noise
and Poisson white noise excitation has been established and its angle stability has been analyzed.
Increasing the Gaussian white noise and Poisson white noise excitation intensity can lead to an
increase in the fluctuation of the power angle curve, as well as an increase in the standard deviation
and expected value of the power angle mean curve, which may decrease the stability of the
power system.

Conclusion:
This study provides a reference for stochastic power systems modeling and efficient
simulation, and has important application value for power system stability assessment and
safety evaluation as well as related patent applications.
Revolutionizing Drug Delivery: The Potential of PLGA Nanoparticles in
Nanomedicine
Authors: Singh Akanksha R. , Athawale Rajani B. 
Published: February 2024

Abstract:
Nanomedicine is an emerging field that utilizes nanoparticles to deliver drugs and
other therapeutic agents to specific cells and tissues in the body. One of the most promising
materials for creating these nanoparticles is Poly(Lactic-co-glycolic Acid) (PLGA), which has
several unique properties that make it well-suited for biomedical applications. These
nanomedicines, made from a combination of lactic acid and glycolic acid, can deliver drugs and
other therapeutic agents directly to specific cells or tissues in the body. This allows for more
precise and targeted treatment, reducing the potential for side effects and improving the
effectiveness of the treatment. Additionally, PLGA nanomedicines are biocompatible and
biodegradable, making them an attractive option for use in a wide range of biomedical
applications to deliver a wide range of drugs, including proteins, peptides, nucleic acids, and
small molecules for various biomedical applications such as neurodegenerative, cardiovascular
diseases, inflammatory disorders, and cancer. In summary, research on PLGA nanoparticles for
biomedical applications is ongoing and has the potential to lead a new and improved treatments
for a wide range of diseases and conditions. Looking ahead, PLGA nanoparticles have the potential
to revolutionize the way we treat diseases and improve human health. As research continues
to advance, we can expect to see new and innovative uses for PLGA nanoparticles in the biomedical
field, leading to the development of more effective and targeted therapeutics. The current
review focuses on the synthesis, physicochemical properties, biodegradation properties of
PLGA, method to prepare PLGA nanoparticles and biomedical application of PLGA. It
examines the current progress and future directions for research on PLGA in drug delivery.
The Socialization Of Terrorism In Canada
Authors: Gilmour John 
Published: February 2024

The academic and institutional battlefield is littered with the best intentions of those attempting to bring a universally recognized definition to the term ‘terrorism’. The concept of ‘where you sit is where you stand’ certainly applies to such endeavors. In addition to considering how best to integrate such fundamental questions as who, what, where, why and how in a definition of the term, attempts have been confounded and complicated by where definitional efforts have been centered within a particular community. Do you adopt a social science or quasi-scientific approach? From a jurisprudence and law enforcement perspective? Terrorist financing? Intent and motivation? Psychological drivers and personal profiles of individual terrorists? Organizational structures? Cultural and anthropological approaches? Rationality and mental health? Historical considerations? Critical study interpretations? All this has made for terrorism being a contested concept over the decades. As observed by Schmid and Jongman, and as we shall explore, “The nature of terrorism is not inherent in the violent act itself. One and the same act can be terrorist or not, depending on the intention and circumstances.” But how terrorism is defined by whatever community is not a trivial issue. Definitions carry political and policy consequences that govern the counterterrorism space and how threats and risks are articulated going forward. How the threat environment endures is often just as much an outcome of how a state elects to respond to the threat, as it is the agenda of terrorist entities. And terrorism charges cannot be prosecuted if there is not at least some notion of how motivations, intentions and acts are defined in statutes.

mHealth Apps for the Self-Management of Low Back Pain: Systematic Search in App Stores and Content Analysis
Authors: Zhou Tianyu , Salman David , McGregor Alison 
Published: February 2024

Background
With the rapid development of mobile health (mHealth) technology, many health apps have been introduced to the commercial market for people with back pain conditions. However, little is known about their content, quality, approaches to care for low back pain (LBP), and associated risks of use.

Objective
The aims of this research were to (1) identify apps for the self-management of LBP currently on the market and (2) assess their quality, intervention content, theoretical approaches, and risk-related approaches.

Methods
The UK iTunes and Google Play stores were initially searched for apps related to the self-management of LBP in May 2022. A repeat search in June 2023 was conducted to ensure that any relevant new apps developed in the last year were incorporated into the review. A total of 3 keywords recommended by the Cochrane Back and Neck Group were used to search apps “low back pain,” “back pain,” and “lumbago.” The quality of the apps was assessed by using the 5-point Mobile App Rating Scale (MARS).

Results
A total of 69 apps (25 iOS and 44 Android) met the inclusion criteria. These LBP self-management apps mainly provide recommendations on muscle stretching (n=51, 73.9%), muscle strengthening (n=42, 60.9%), core stability exercises (n=32, 46.4%), yoga (n=19, 27.5%), and information about LBP mechanisms (n=17, 24.6%). Most interventions (n=14, 78%) are consistent with the recommendations in the National Institute for Health and Care Excellence (NICE) guidelines. The mean (SD) MARS overall score of included apps was 2.4 (0.44) out of a possible 5 points. The functionality dimension was associated with the highest score (3.0), whereas the engagement and information dimension resulted in the lowest score (2.1). Regarding theoretical and risk-related approaches, 18 (26.1%) of the 69 apps reported the rate of intervention progression, 11 (15.9%) reported safety checks, only 1 (1.4%) reported personalization of care, and none reported the theoretical care model or the age group targeted.

Conclusions
mHealth apps are potentially promising alternatives to help people manage their LBP; however, most of the LBP self-management apps were of poor quality and did not report the theoretical approaches to care and their associated risks. Although nearly all apps reviewed included a component of care listed in the NICE guidelines, the model of care delivery or embracement of care principles such as the application of a biopsychosocial model was unclear.

Published: February 2024

Teacher performance significantly determines the quality of education, and various methods are employed to enhance it. Factors influencing teacher performance include personal, organizational, and managerial aspects. This study aims to examine the role of organizational commitment in the relationship between collaborative leadership and teacher performance. Participants in this research were recruited using purposive sampling, and the criteria included permanent teachers with a minimum of 2 years of experience, totaling 195 individuals. This correlational study utilized Leadership Scale, Organizational Commitment Scale, and Teacher Performance Scale to collect data, which were then analyzed through the Hayes Process Model 4. The findings indicate a relationship between collaborative leadership and teacher performance (r=0.759, p<.01) and organizational commitment with teacher performance (r=0.450, p<.01). Commitment serves as a mediator in the relationship between collaborative leadership and teacher performance, with an indirect effect value of 0.047, se=0.018, cl (0.015 – 0.089), confirming all hypotheses in this study. The study shows that teacher performance is influenced by the collaborative leadership style of the school principal mediated by the organizational commitment of the teachers. To enhance teacher performance, school principals can employ a collaborative leadership model and strengthen organizational commitment.

Published: February 2024

O número de casos de dengue no continente americano, no primeiro semestre de 2023, superou o total de casos de 2022 e o Brasil lidera com 2,3 milhões de ocorrências da doença e 769 mortes. A dengue se expande no mundo e já é considerada endêmica em mais de 100 países. Este estudo objetiva caracterizar o perfil dos óbitos por dengue, no período de 2015 a 2023, em uma cidade do interior do estado de São Paulo. Este é um estudo transversal, retrospectivo e descritivo, com análise de dados secundários do Sistema Nacional de Notificação (Sinan), Sistema de Mortalidade (SIM) e banco de dados dos óbitos por dengue, do comitê de mortalidade da vigilância epidemiológica municipal. A capacidade das equipes de saúde em identificar os sinais e sintomas ocorreu em apenas 42,9% dos casos antes da internação e do óbito, seguida por no dia do óbito (11,7%) e após o óbito (8,8%). A mortalidade por dengue predominou em indivíduos do sexo masculino (51,4%), com idade mediana de 74 anos. A análise dos dados demonstrou que o manejo clínico da dengue ainda é desafiador para a equipe de saúde, que precisa se manter permanentemente capacitada para o reconhecimento dos sintomas, sinais de alarme e gravidade, para a correta condução de cada caso, visando a redução da mortalidade.
