Visual disturbances may result in a long-term complication after mild traumatic brain injury(mTBI) in children. The purpose of the study was to assess the visual acuity (VA) disturbances and refractive status in children with persisting symptoms after mild traumatic brain injury. The research aimed 48 patients with persisting visual symptoms after mTBI. Visual symptoms and refractive status were assessed. Thus, in the mTBI group, the visual acuity for the right eye was of 0.09—0.5 in 83.7% (40 patients), in 16.3% (8 patients) – right eye 0.6—0.8, compared to the control group, were 62% of patients had the visual acuity ranged almost in 1.0, just 14% (7 patients) was ranged 0.09-0.5 and in 24% (12 patients) la 0.6—0.8. The visual acuity for the left eye in the research group was of 0.09—0,5 in 89.8% (43 patients), in 10.2% (5 patients) –for the left eye was 0.6—0.8, compared to the control group, were 66% of patients had the visual acuity ranged almost in 1.0, just 24% (12 patients) was ranged 0.09-0,5 and in 14% (5 patients) – 0,6—0.8. VA is affected primarily after head trauma although it improves in a time perioranginged between 3 and 6 months after the trauma. Autorefraction data usually will reveal slight hyperopia with a possible astigmatic component ranging between 1D to 3D, and in 4.1%–8.2% cases slight myopia also ranged between 1D and 3D.

Published: October 2024

One of the problems of fistulizing surgery in glaucoma is the appearance of the healing process in the area of the intervention and in a number of cases the pressure changes are gradually limited. The Intraocular Pressure is rising again. To prevent this disadvantage, new surgical methods are proposed to avoid these evolutionary deficiencies. Elaboration and development in clinical practice of new ways and remodeling of pathogenic orientation for glaucoma microsurgery techniques to ensure safe and sustainable reduction of IOP as well as stabilization of the visual functions of patients with glaucoma. The authors propose the inclusion under the scleral and conjunctival flap of different auto or allodrainage.[1] However, we propose the use of bioabsorbent drainage „Glautex” model DDA and SDA in refractory glaucoma surgery.The study included 24 glaucoma patients, the age of the patients being between 4263 years, who previously underwent fistulizing intervention. Preoperatively, all patients underwent complex examination. In all patients, surgery was performed on the previously unaffected area. The observation period was 1 year, during which time the patients were examined in a complex schedule every 1-3-6-12 months. The implantation of the “Glautex” drainage model DDA and SDA allowed the reduction of IOP and the maintenance of hypotensive effect in the early postoperative period in all cases and at a distance of 1 year postoperatively, IOP being 20.5 ± 2.5 mmHg, at 17 eyes (70, 8%) without the use of drug therapy, in 4 (16.6%) cases on a monotherapy background, in 2 eyes (8.3%) they needed combined drugs, in one case IOP was undercompensated (4.1%). Moderately diffuse filtration bubble in 95.9% of cases, and in 4.1% of cases the bubble is flat.

Authors: Bobescu Doina , Cusnir Valeriu , Dumbraveanu Lilia
Published: October 2024

Inflammatory (uveitic) glaucoma is a type of secondary glaucoma, which occurs due to eye inflammation, is characterized by a persistent or periodic increase in intraocular pressure (IOP) and glaucomatous lesions of the optic nerve. The mechanism by which inflammation increases IOP is not yet fully elucidated, and pathogenic pathways remain shrouded in mystery. The consequences of the disease lead to a drastic decrease in visual acuity and invalidation of young, able-to work patients. The treatment of this type of glaucoma will be personalized for each patient, aiming at the administration of standard antiglaucomatous remedies, performing surgeries if indicated and applying new therapeutic trends. This article will be useful for the clinician to help a patient with inflammatory glaucoma. It aims to elucidate the etiopathogenesis and key treatment elements. Being a review of literature, it will be helpful in determining the cause, understanding all known pathogenetic pathways and making a therapeutical decision. All this steps are designed to preserve visual function at the best possible level.

Published: October 2024

Aging is a universal process of constant reducing of the functioning of a complex system over time, affecting all levels of its organization that impede self-renewal processes. In the structure of the geroprotective therapeutic effect, the main role is given to combat oxidative stress. The most important natural remedy without drugs with this property is the ozoneoxygen mixture, whose effect on the human body is verified by studies conducted both nationally and internationally. 119 patients who underwent outpatient treatment at the Ozone Center in Nizhny Novgorod, Russia, were examined, the basic diagnosis was coronary heart disease, stable angina CF II-III. Parenteral administration of ozonated saline normalizes the pro- and antioxidant serum balance of elderly patients with coronary heart disease. After a course of ozone therapy, there is a decrease in the level of lipid metabolism - total cholesterol, LDL-C, triglycerides. Intravenous administration of low ozone levels improves endothelial function by lowering high levels of nitric oxide and endothelin. Ozone therapy reduces the ability of platelets to aggregate and improves the rheological properties of the blood of elderly patients with coronary heart disease.

Road transportation is not only a vital component of how cities grow and how society functions, but it is also a signif icant factor that can affect the frequency of serious accidents and traumas. Human failure is not omitted, addressing it at the system level, involving the prevention of fatal and severe accidents, reducing mortality, and the cost itself. With the aim of outlining the best ways to improve road traffic, and prevent road trauma we have observed the experience of different countries in this regard. As materials and methods, we used Pubmed and Google Academic databases to identify and analyze in detail each strategy or plan with the period included in the study 2010- 2022, in 10 countries. The results show that each of the countries researched followed the example of the Global Plan and implemented respective strategies. Each country focused on particular errors in the country and formed different methods of improvement. As a suggestion for developing the updated strategy, it would be effective to establish the current gaps in their own system more clearly. In conclusion, road safety is a shared responsibility, recognizing the role of policymakers as well as planners and public health professionals, all parts of the system need to be strengthened to multiply their effects so that if one part fails, people are still protected.
Global vaccination policies in rotavirus infection
Authors: Birca Ion
Published: October 2024

Before rotavirus vaccines first became available in 2006, almost every child up to the age of 3-5 years had at least one episode of diarrhoea due to rotavirus infection. According to statistics, in the 2000s rotavirus was the leading cause of severe, dehydrating diarrhoea in children under 5 years of age globally, causing an estimated 500 000 child deaths and more than 2 million hospitalisations worldwide. Currently available rotavirus vaccines are live, oral, attenuated rotavirus strains of human and/or animal origin that replicate in the human gut to elicit an immune response. The first 2 rotavirus vaccines prequalified by the WHO were RotaTeq27 (Merck & Co. Inc., Whitehouse Station, NJ, USA) in 2008 and Rotarix (GlaxoSmithKline Biologicals, Rixensart, Belgium) in 2009. Each of the WHO pre-qualified vaccines against rotavirus has demonstrated a high level of safety. Rotavirus vaccination is costeffective in most low- and middle-income countries compared to no vaccination. Given the continuing burden of severe rotavirus gastroenteritis even after vaccination and in the second year of life in high morbidity and mortality settings, current research priorities include investigating alternative schedules, including neonatal schedules and booster doses.

Authors: Grivenco Alexandru , Rudico Andrei , Peltec Angela
Published: October 2024

Introduction. Fatty liver disease (FLD) is defined as the accumulation of liver fat (hepatic steatosis) in >5% of hepatocytes with or without inflammation and fibrosis. Quantitative imaging techniques can provide objective continuous metrics associated with liver fat content and be recorded for comparison when patients receive check-ups to evaluate changes in liver fat content. The aim of the study was to identify the accuracy of non-invasive imaging techniques in diagnostic FLD. Material and Methods. A total of 1034 studies were identified on the PubMed database. After removing duplicates, 728 titles, and abstracts were screened. Analysed correlation between histopathologically confirmed steatosis and imaging techniques. Results. Controlled attenuation parament (CAP), ATI Attenuation imaging (ATI), Attenuation measurement function (ATT), and Hepatorenal index were analyzed. CAP is the first method based on attenuation of the ultrasound beam, but the limitations of this method are caused by the impossibility to determine the exact location of the region of interest. ATT and ATI have been developed to improve this situation, and these metrics can be used to evaluate the degree of fatty liver on grayscale ultrasonography in real-time with a correct region of interest.CAP showed suboptimal performance in quantifying liver fat content, especially in mild steatosis, which limited its use as a golden standard. Conclusions. Greyscale ultrasound has limited diagnostic performance in mild steatosis. The CAP method is more difficult to be used in overweight and obese patients, but these are the most common patients in FLD. ATT/ATI are the universal methods.

Published: October 2024

Autoimmune hepatitis (AIH) is a progressive chronic liver disease of unknown cause, with varied clinical picture and evolution. The diagnosis of autoimmune hepatitis is based on histological changes (interface hepatitis), characteristic clinical and biological signs (hypertransaminasemia and increased serum IgG concentration), with the presence of one or more characteristic autoantibodies. The purpose of this presentation was to analyze the evolution of the disease of a patient with autoimmune hepatitis during pregnancy, the safety of the treatment, and the long-term results/complications of immunosuppressive therapy. During this period, the patient periodically stopped the treatment, had a pregnancy that ended with the intrauterine death of the fetus, and then managed to give birth to a healthy child. Predniso(lo)n as initial therapy, followed by the addition of azathioprine after two weeks, are the first-line treatment for AIH, including in pregnancy. In our patient, immunosuppressive therapy with prednisone and azathioprine was safe and effective in inducing and maintaining remission, without significant complications or exacerbation during the pregnancy. Thus, an early established diagnosis and the prompt application of appropriate treatment, strict monitoring of the disease and of immunosuppressive treatment complications, can improve the evolution of AIH, slowing the progression of the disease.

Published: October 2024

Even if the Romanian language, on the one hand, and the English language, on the other hand, have different historical backgrounds, with no genetic relatedness, there are quite a number of similarities in expressing politeness in both languages. Our present survey is focused on the investigation of politeness from the socio-cultural point of view, emphasizing the similarities and differences that exist between the two languages. We have discussed the main linguistic theoretical aspects regarding this phenomenon, from different points of view: the conversational view, the face-saving view and politeness viewed as a conversational contract. Afterwards, we have approached in detail the problem of linguistic politeness, highlighting the social and cultural factors that have the strongest impact on choosing a certain way of addressing. We have come to the conclusion that the similarities and differences that exist among the Romanian and English languages as regards politeness expression are triggered by various value systems and by different cultural and social systems.

Background: Cyclophosphamide is a widely used chemotherapy drug, known for its cytotoxic and mutagenic effects on mammalian tissues and cells. Olive oil, rich in antioxidants, has potential protective effects against drug-induced organ damage. This study investigates the protective role of olive oil against cyclophosphamide-induced toxicity in mice. Objective: To evaluate the protective effects of olive oil against cyclophosphamide-induced kidney toxicity in rats. Material and Method: Male albino mice (n=9) were divided into three groups: Control, Cyclophosphamide (150 mg/kg), and Cyclophosphamide (150 mg/kg) + Olive Oil (200 mg/kg). After one week of treatment, kidney tissues were collected and stained with hematoxylin and Eosin for histopathological analysis. Results: The administration of olive oil led to a significant decrease in cellular damage of the kidney tissue. In this study the histopathological examination revealed marked improvement in kidney tissue architecture, with reduced cellular damage, inflammation, and fibrosis compared to the group treated with cyclophosphamide alone. These findings suggest that olive oil has a protective effect against cyclophosphamide-induced hepatic and renal toxicity in mice. Conclusion: Cyclophosphamide caused significant histopathological damage to kidney tissues in mice. Co-administration of olive oil mitigated these adverse effects, likely due to its antioxidant properties. This suggests that olive oil may serve as a protective adjunct in cyclophosphamide chemotherapy.

Based on the spiritual leadership approach, encouraging employees to participate in ta'awun behavior enhances human resources efficiency within a business organization. Researchers have studied many leadership models, but only a few have explored spiritual leadership models and OCBI and OCBO on human resource performance. The study aims to contribute to the growth of research into spiritual leadership models, OCBI, and OCBO behavior about HR performance. This study investigates the mediating role of ta'awun behavior in the relationship between spiritual leadership and HR performance. This study emphasizes 190 employees from PT Arkatama Solusindo and PT Digi Partner Studio and a quantitative research paradigm using the Partial Least Squares (PLS) analysis tool. According to this research, the spiritual leadership model is the most effective factor for improving human resource performance. Its influence can be effectively reduced by OCBI and OCBO behavior. OCBI behavior serves as a mediator for the impact of spiritual leadership on HR performance. Meanwhile, the mediating variable OCBO does not have a mediating role.

This work presents an antitheft alert system that integrates multiple technologies to offer a high level of detection, monitoring, and barrier protection through cost-effective methods and equipment. It implements a virtual LASER fence framework, enabling individuals to establish real-time surveillance at locations such as homes, farms, or any other area of interest. The proposed system detects objects that cross the vision line between the laser source and optical detector. When the laser beam is interrupted, alert data—including an instant notification via email and recorded footage of the intrusion—is sent to the security provider’s device using internet services like Gmail. The system is powered by a Raspberry Pi as the central processor, along with components like the Pi camera and laser modules. This solution addresses issues found in existing frameworks and ensures non-destructive consequences for the intruder.

An In-Depth Analytical Study Of The Works Of Sayyid Qutb: Ideology, Influence, And Legacy
Authors: Ahmed Dr. Farid Uddin , Hoque Dr. Raysul , Rahman Abdur
Published: October 2024

Sayyid Qutb, born in 1906 and executed in 1966, was a prominent Egyptian writer, educator, and Islamic theorist. He played a significant role in shaping modern Islamic thought and was a key figure in the Egyptian Muslim Brotherhood during the 1950s and 60s. Qutb’s writings, particularly his most famous book “Ma‘âlim fî al-Tarîq” (Milestones), published in 1964, became central to the ideology of Qutbism. In “Milestones”, he critiqued contemporary societies, arguing that despite their technological progress, they lived in a state of “Jâhiliyyah” (ignorance), disconnected from true Islamic principles. Qutb advocated for a resurgence of Islam through jihad to restore a purer form of the faith. His works have greatly influenced modern Islamic movements. After being convicted of plotting to assassinate Egyptian President Gamal Abdel Nasser, Qutb was executed in 1966. His writings, including “Fî Ẓilâl al-Qur’ân” (In the Shade of the Qur’ân), continue to impact debates on Islamic governance and the role of religion in political life.
Follow Debelyanov‘s Shadow
Authors: Ichevska Tatiana
Published: October 2024

Georgi Raichev feels the continuous need to remember and tell about his friend Debelyanov and he does so –in practice, until the end of his life. The present text will try to develop the (hypo)thesis that, in addition to the standard memorial formats (in jubilee collections, memorial sheets, etc.), in which Raychev recalls moments from his joint experiences with Dimcho, he implants the personality in a specific way to his friend and in one of his first significant texts – the story “Tiny World” (1919). It is about both the possibility of drawing analogies between character traits of the main character and the poet, as well as the scattering of moments from Debelyanov‘s (pre)war life and/or from his (mainly frontline) lyrics throughout the narrative.

Baco Exu do Blues e as representações de homens negros sobre si
Authors: Borsa Matheus Eduardo , Soares Claudete Gomes
Published: October 2024

Esse artigo trata de analisar as representações sobre as masculinidades negras no tempo presente a partir das rimas e falas de Baco Exu do Blues, nome artístico de Diogo Álvaro Ferreira Moncorvo. A nossa proposta é abordar as disputas e dinâmicas de (des)construção das imagens produzidas historicamente sobre os homens negros sem desconsiderar as ambiguidades e as teias de poder que podem levar sujeitos inscritos em masculinidades subalternas a reproduzirem repertórios da masculinidade hegemônica em sua afirmação de poder. O aporte oferecido pelas Ciências Sociais - especialmente os Estudos Culturais e os escritos de Stuart Hall - articulado à sensibilidade teórico política do feminismo negro e do feminismo decolonial foram de grande valia para a construção dessa análise, na qual interligamos os temas: masculinidades, mídias digitais e colonialidade.
Antropologia política e gênero: uma breve revisão histórica
Authors: Ferreira Vinicius Kauê
Published: October 2024

Este ensaio propõe uma breve revisão histórica dos debates sobre poder e gênero na literatura antropológica. Demonstro que a problemática da desigualdade sexual já aparece em trabalhos clássicos da antropologia evolucionista do século 19 como elemento-chave de compreensão do poder. Em seguida, percorro as contribuições de trabalhos precursores do culturalismo americano que colocam em evidência contextos de autoridade feminina. Abordo também os debates sobre a universalidade da dominação masculina de meados do século 20, assim como sua contestação com os debates dos anos 1980 sobre a relacionalidade das dinâmicas de violência de gênero. Concluo, então, com discussões mais recentes sobre as articulações entre Estado, nação e mulheres no século 21. Inscrevendo-se numa Antropologia Política, mostro que a antropologia feminista foi fundamental para a consolidação da Antropologia Política como um todo.
