Fractures in children and adolescents are a significant public health concern. The incidence of fractures varies based on age, sex, and anatomical site, with falls, sports-related injuries, motor vehicle accidents, child abuse, and pathological conditions identified as primary causes. Risk factors such as age, sex, physical activity, bone mineral density, body composition, and genetic factors contribute to fracture occurrence. Preventive measures targeting modifiable risk factors and promoting safety in physical activities are crucial for reducing the burden of fractures in children and adolescents. This review aims to provide a comprehensive understanding of the epidemiology and etiology of fractures in children and adolescents. Understanding the epidemiological patterns and etiological factors can guide the development of effective prevention strategies and optimize fracture management in this population.

Etyka gatunku Jürgena Habermasa jako propozycja uregulowania biotechnologicznego postępu
Authors: Dubchak Olena
Published: July 2023

Według Jürgena Habermasa w warunkach eugeniki liberalnej ludzka samowiedza gatunku może ulec zmianie, dlatego należy wprowadzić regulacje, które pozwolą sprawować kontrolę nad wykorzystywaniem i nad rozwojem nowych biotechnologicznych metod. Zachowanie obecnej samowiedzy jest ważne, aby zapewnić podstawę dla funkcjonowania uniwersalistycznie pojmowanej moralności, pozwalającej osobom w sposób sprawiedliwy regulować swoje konflikty. Na dwie przesłanki samowiedzy gatunku składa się: postrzeganie siebie przez osoby jako wyłącznych autorów własnego życia oraz jako członków społeczeństwa, między którymi panują symetryczne relacje. Zachowanie takiej samowiedzy nie jest możliwe w sytuacji, gdy genetycznymi zadatkami jednych osób przed ich urodzeniem rozporządzali inni. Habermas proponuje, aby rozwój biotechnologii poddać regulacjom zgodnym z etyką gatunku, która jest rekonstrukcją warunków samowiedzy do tej pory przez nas posiadanej. Sformułowana przez niego etyka gatunku zakłada nierozporządzalność genetycznymi cechami nienarodzonych, jednak nie przesądza o stosowaniu genetycznych ingerencji w celach terapeutycznych, na które, według Jürgena Habermasa, można zakładać zgodę przyszłych osób, nie naruszając samowiedzy stanowiącej podstawę uniwersalistycznej moralności.
The design thinking method as an example of social innovation in action based on the case study of ProPoLab
Authors: Dybał Mariusz
Published: July 2023

The aim of the paper is to explain and to understand the processes of public services delivery from the perspective of social innovation. Concepts of co-creation and social innovation were elaborated on the basis of one of ProPoLab’s milestones: Design Thinking Workshops. Hence the research object are the residents (mostly seniors) of the district of Popowice, while the quality of life of seniors is its subject. The main research goals were firstly to identify needs of residents in relations to public services, and secondly to design a socially innovative solution that will increase the quality of life of seniors. To achieve these goals, the following research tasks have been set: (a) identifying the needs of seniors, (b) identifying which of those needs are being met locally and which are not, (c) to identify what are the relations between neighbors and the attitude towards cooperation, (d) identifying how the needs of seniors could be met. The research mainly covers the period of 2018–2019. Following research methods have been used: analysis of scientific literature and normative documents, design thinking methodology, comparative analysis and statistical analysis. Utilizing design thinking methodology helped to reveal that the problem of communication between residents can be solved by creating a small, accessibly located community/activity center in their housing estate. This place should meet the needs of activity and self-fulfillment, exchange of information and intergenerational exchange. Time availability is very important, and the space intended for seniors should function in an hourly timeframe similar to daycare centers. Residents should be included in drafting a program to better identify and respond to their needs. Seniors would likely be happy to provide volunteer work in such a place. The facility should be located in the middle of the housing estate so that all residents have easy access to it, optimally in pleasant natural surroundings (i.e. near vegatation), as well as in close proximity to playgrounds for children.
The Transformative Power of the Oromo Protests in Ethiopia: Resilience and Political Change
Authors: Tolla Aden Dejene , Royo Alvaro Oliver
Published: July 2023

This article explores why the Oromo protests have transformed the Ethiopian political landscape since demonstrators took the streets in November 2015. It also examines the relationship between the two pillars of the ruling Ethiopian People’s Revolutionary Democratic Front (EPRDF), ethnic federalism and developmentalism, and the Oromo protests. The study aims to illustrate the connection between the Ethiopian state’s fundamental strategies and the capacity of popular movements to bring about political change. The study has used a qualitative research approach with both primary and secondary data. Semi-structured in-depth interviews were conducted and recorded with a voice recorder, and data was analysed through thematic analysis. The findings of the research show, first, that the securitisation of development strategy performed by the EPRDF triggered the protests. And second, that the primordial understanding of ethnicity, as defined in the Constitution, contributed to the articulation of the Oromo protests as a movement. The study concludes that the Oromo protests will pave the way for reform because they reflect the regime’s failures and also represent the demands of the larger part of Ethiopian society.

Published: July 2023

The development of non-toxic, biocompatible and antibacterial hydrogels are ideal biomaterials as wound dressing material for promoting wound healing. Thus, we report the development of a low-cost biomacromolecule-based triad nanocomposite hydrogel. Gelatin, a collagen hydrolysate based biomacromolecule, polyvinyl alcohol (PVA), and green-synthesized silver nanoparticles (AgNPs) form the hydrogels for wound dressing application. Gelatin enhances the efficiency of the hydrogel blended with synthetic macromolecule PVA. Silver nanoparticles (AgNPs) synthesized using Musa balbisiana (Bhimkol) peels aqueous extract were incorporated into the PVA-Gelatin hydrogel blend. The developed PVA-gelatin-AgNPs triad nanocomposite hydrogel films were characterized and studied by various spectroscopic and analytical techniques. The incorporation of AgNPs into the gelatin-PVA blend offers better stability, improved water vapour transmission rate (WVTR), surface contact angle, swelling ratio and mechanical properties compared to the native PVA-gelatin blend. The PVA-gelatin-AgNPs triad bionanocomposite hydrogel films showed potent antibacterial efficiency against the commonly present microbes in wounds i.e., E.coli and S. aureus. The hydrogel films showed no toxicity against the BJ normal human foreskin fibroblasts cells. Our composite hydrogel was found to accelerate wound healing, efficiently protect the wounded skin surface against exudate accumulation/dehydration, and prevent bacterial growth and infection. Thus, these gelatin-PVA-AgNPs triad nanocomposite hydrogels acts as ideal for wound dressing applications.

Forsythia suspensa (Lianqiao) has long been touted for its anti-viral effects in folklore. Although promising, limited research were conducted to evaluate its potential in defending the severe acute respiratory syndrome coronavirus (SARS-CoV-2). This study evaluated the fruits of Forsythia suspensa (Lianqiao), an important economic crop, for the chemical components of its water and ethanol extracts, along with their inhibitory effects on SARS-CoV-2 spike protein binding to angiotensin-converting enzyme 2 (ACE2), inhibitions of ACE2 activity, and capacities to scavenge the selected free radicals. A total of 42 compounds were tentatively identified in the extracts by HPLC-MS/MS analysis. Both water and ethanol extracts of Lianqiao showed great inhibition of ACE2 activity and the binding affinity between SARS CoV-2 spike protein and ACE2. Furthermore, the water extract had greater scavenging capacities against HO●, DPPH● and ABTS●+ than the ethanol extract. Findings of this research contribute to the knowledge of different extraction solvent systems and support the potential of Lianqiao in reducing the risk of coronavirus infection and alleviating the symptoms after infection.

Authors: Mohamed Khalid Osman , Soumit Sozan Mudather , Elseed Aziza Abdalmahnoud , Allam Wamda Ahmed , Soomit Amro Mudather , Humeda Humeda Suekit
Published: July 2023

Background:
Internet addiction (IA) has been studied extensively worldwide and has various characteristics that could be detrimental to social, psychological, and functional aspects. Additionally, IA has become a global health issue, especially among teenagers and young adults, and different countries have different rates of internet overuse prevalence. Unfortunately, few studies have been done on medical students in Sudan to explore the effect of internet addiction on psychological distress.
Objective:
This study aimed to measure the prevalence of internet addiction, the risk factors associated with it, and its impact on psychological distress among undergraduate medical students.
Methods:
This cross-sectional study was conducted among medical students of all academic levels at National University using a systematic sampling technique. An online structured questionnaire was used, which included socioeconomic data and the 20-item Internet Addiction Test (IAT) to assess the presence and severity of IA, as well as the 10-item Kessler questionnaire to assess psychological distress. Additionally, to assess the association between internet addiction and different variables, a chi-square test was utilized. A p-value of less than 0.05 was considered statistically significant.
Result:
A total number of 307 medical students participated in this study. Most of them were female (63.8%). The majority (78.5%) were aged 18–22 years, and the prevalence of internet addiction was 75.6% (n = 232). The level of addiction was as follows: 39.7% were mild addicts, 33.2% were moderate addicts, and 2.6% were severe addicts. In the chi-square test, the prevalence of internet addiction was significantly higher among students aged 18–22 years (78.4%) and above (70%) than among students aged less than 18 years (57.7%) (P = 0.044). A strong statistically significant association was found between internet addiction and psychological distress (P = 0.00).
Conclusions:
The current study reveals that the prevalence rates of internet addiction among medical students at National University are very high, with addiction affecting psychological health. Therefore, effective intervention strategies are required to enlighten students on how to restrict excessive internet usage and minimize its impact on psychological status.

Introduction
This study aimed at comparing the efficacy of the PHILOS plate and the hook plate for the treatment of the isolate split greater tuberosity fracture of humerus.
Methods
All patients with isolate split humeral greater tuberosity fractures that were treated using PHILOS plate or hook plate from January 2018 to June 2021 were retrospectively investigated. Data on the above-mentioned patient demographics, injury characteristics, preoperative and postoperative imaging, length of incision, operative time, intraoperative blood loss, and outcomes were recorded and then investigated. Furthermore, the inclusion criteria and exclusion criteria were formulated.
Results
A total of 193 patients were diagnosed with proximal humerus fractures in our institution,and 31 patients conformed to the inclusion criteria. In accordance with the different fixed methods, the patients fell into two groups. To be specific, 19 patients in group A were administrated with PHILOS (proximal humeral internal locking system) plate, and 12 patients in group B were administrated with hook plate. No significant difference was identified in sex, age, injury mechanism, dominant side limb (yes or no), shoulder joint dislocation (yes or no) between two groups. However, in Group B, the operative time was shorter, blood loss was less, length of incision was shorter than Group A's Moreover, pain was evaluated at third day and fifth day after surgery, the pain in fifth day was less in group B than group A, pain in third day and last follow up was no difference between two groups. The constant score, the DASH score, the ROM were evaluated at the last follow up, no significant difference was identified between two groups. The complications were also collected, five patients administrated with PHILOS plate were diagnosed subacromial impact, and two patients administrated with hook plate were diagnosed rotator cuff injury.
Conclusion
The hook plate can achieve favorable results in the treatment of isolate split humeral greater tubercle fractures, with less blood loss, shorter operative time and shorter surgical incisions than the PHILOS plate.
Revealing the Roles of Pyroptosis Genes in Immune Infiltration for Intervertebral Disc Degeneration
Authors: Ma Miao , He Xuegang , Luo Zhangbin , Zhang Guangzhi , Wang Yajun , Kang Xuewen
Published: July 2023

Background
The reduction of the nucleus pulposus is a significant contributing factor to intervertebral disc degeneration (IDD), with pyroptosis being a prominent cause. However, further investigation is required to better understand the mechanisms of pyroptosis in IDD. This study aimed to identify the hub genes involved associated with pyroptosis in IDD.
Methods
The expression matrices of two IDD datasets were obtained from the Gene Expression Omnibus dataset. Subsequently, differentially expressed gene (DEG) analyses were performed on both datasets to identify pyroptosis-related DEGs (PRDEGs). PRDEGs underwent correlation analysis, chromosomal location and functional similarity analysis, and a series of bioinformatics methods to identify hub genes. Finally, networks comprising long non-coding ribonucleic acid (lncRNA), microRNA (miRNA), and hub genes were constructed using the Encyclopaedia of RNA Interactomes and LncBase databases.
Results
Following the intersection of DEGs and pyroptosis-related genes, 18 PRDEGs were identified. Gene Ontology and Kyoto Encyclopaedia of Genes and Genomes enrichment analyses revealed that PRDEGs were primarily associated with the response to lipopolysaccharide and nucleotide-binding and oligomerisation domain (NOD)-like receptor (NLR) signalling pathways. Seven PRDEGs, namely NOD2, NLR family caspase activation and recruitment domain (CARD) containing 4, caspase 5, absent in melanoma 2, NLR family pyrin domain containing 3, apoptosis-associated speck-like protein containing a CARD, and tumour necrosis factor, were identified as hub genes. The association of IDD with resting memory CD4+ T cells was confirmed through CIBERSORT. Finally, a competing endogenous RNA network involving the seven PRDEGs was constructed.
Conclusion
Pyroptosis in IDD was associated with two pathways and seven hub genes. Additionally, four lncRNAs played a crucial role in the pathogenesis and progression of IDD. These potential pyroptosis-related biomarkers might offer novel approaches for further exploration into the underlying mechanisms of IDD.
Broad learning system based on adaptive lasso
Authors: Lu Xinyu , Zhang Qian , Liang Tao
Published: July 2023

Broad learning system is an emerging method, which has achieved outstanding performance in regression and classification problems. This paper proposes a novel algorithm called Broad Learning System based on adaptive lasso (AdL1-BLS) to reduce model size and improve model generalization performance. The proposed AdL1-BLS introduces the weighted L1-norm penalty into BLS, adaptive lasso is used to assign different adaptive coefficients to each output weight of BLS. Because of the effect of adaptive coefficients, the output weight of BLS gets varying degrees of compression rates, which avoids the problem of over-sparse network structure and reduces the prediction error of the network, which better solve the BLS over-fitting problem, and improves the generalization of BLS under the premise of ensuring the sparseness of the network. Finally, the experiments on several commonly used regression data sets are carried out to verify the feasibility of the proposed AdL1-BLS. The experiment results indicate that AdL1-BLS can reduce model complexity without loss of prediction accuracy and improve the model interpretability.
