Background: Guillain-Barré syndrome (GBS) is an acute, immune-mediated post-infectious polyradiculoneuropathy usually presenting with symmetrical ascending weakness, diminished deep tendon reflexes, and non-specific sensory symptoms. GBS is in essence an autoimmune disorder, and the underlying mechanism is thought to result from so-called molecular mimicry. This hypothesis is further supported by approximately 2/3 of the patients having a preceding infection. In most cases, the infectious trigger occurs in the gastrointestinal or respiratory tract, with the disease manifesting within four weeks. Even though it most commonly affects children aged 1 to 5 years old, there are rare cases reported in neonates and infants. Case Presentation: We report a case of a 6-month-old infant with Guillain-Barré syndrome following a respiratory infection. The diagnosis was confirmed through cerebrospinal fluid analysis, EMNG, spine MRI, and clinical assessment. Positive human herpes virus 6 (HHV-6) in cerebrospinal fluid suggested a potential infectious trigger. The infant was treated with intravenous immunoglobulin and ganciclovir, requiring intensive care and mechanical ventilation. Recovery involved gradual neurological improvement and restored motor function over 30 days. Conclusion: GBS is a rare disorder, especially in children and requires multidisciplinary management to prevent complications from occurring and thereby improve the prognosis of patients. Upon arrival at the emergency department, all patients should be carefully evaluated, looking for autonomic and respiratory dysfunction signs. Generally, pediatric patients have a better prognosis compared to adults. Initiation of treatment in the early stages of the disease leads to a faster recovery and consequently fewer sequelae.

Background: Thyroid hormones are essential regulators of energy expenditure, thermogenesis, and body composition. Although overt thyroid dysfunction is well known to alter basal metabolic rate (BMR) and body mass, emerging evidence suggests that even hormonal variations within the reference range may exert measurable effects on metabolic and body composition profiles. Women of reproductive age represent a population particularly sensitive to hormonal oscillations due to the interplay between endocrine, reproductive, and cardiometabolic health. Objective: The study aimed to a) analyze thyroid hormone levels (TSH, FT3, FT4) alongside anthropometric and body composition parameters in women of reproductive age; b) examine thyroid hormone levels, BMR, and body composition parameters across age groups; and c) investigate associations of thyroid hormones with BMR, body composition components, and unfavorable body composition patterns (visceral adiposity, elevated metabolic age, obesity) as well as metabolic indicators.. Methods: A total of 117 women aged 18–45 years were included in this cross-sectional, observational study conducted in Bosnia and Herzegovina between September 2023 and November 2024. Thyroid hormone levels were measured using electrochemiluminescence assays, while body composition was assessed by bioelectrical impedance analysis. Statistical analyses included descriptive methods, Pearson’s correlation, and Chi-square testing, with significance set at p<0.05. Results: TSH showed significant positive associations with fat-free mass, muscle mass, and BMR (p<0.05). FT3 was inversely correlated with metabolic age and visceral fat, while FT4 demonstrated weak negative associations with fat-free mass and metabolic age (p<0.05). Significant age-related differences were observed in fat percentage, fat mass, BMI, visceral fat, and metabolic age, with the most unfavorable profiles in women aged 31–40 years. Conclusion: Thyroid hormones, even within the reference range, are associated with body composition and metabolic parameters in women of reproductive age. Their role as early indicators of unfavorable metabolic patterns highlights potential implications for reproductive and cardiovascular risk assessment.

Background: Relationship between preoperative anemia (PA) and postoperative delirium (POD) is not still completely clear and totally proven for surcigally treated patients. This study tries to unveil that connection in patient surgically treated for colorectal cancer (CRC). Objective: The aim of this study is to examine relationship between PA and POD in patients surgically treated for CRC and improve preoperative preparation and recognition of critical risk groups of patients for POD. Methods: Out of 62 patient were analysed in prospective method. All patient have been operated for CRC in Surgical clinic of University clinical centre Tuzla from june until december of 2024. Patients were divided in 2 groups depending on presence of PA. Presence of PA is defined as blood hemoglobin concentration (HGB) lower than 130 g/L (<13 g/dL) or hematocrite (HCT) lower than 39% in grown up men and HGB <120 g/L (<12 g/dL) or HCT<37% in grown up women. Incidence of POD was observed and noted postoperatively. POD was diagnosed and confirmed with CAM test (Confusion Assessment Method), which was done inside first 2 hours after surgery and patient extubation. Noted datas were analysed with descriptive and analytic statistic methods. Results: POD incidence was 27% (17/62) on the first postoperative day. After analysis statitically significant realtionship was found between PA and POD (ρ=0.324; p<0.05). Realised corellation is on the significance level of 0.05 (95%), it has positive direction and waek intensity. POD occurs 4,5 times more often in patients with PA. (OR= 4,500; 95% IP: 1.355–14.944). Conclusion: PA is connected with increased number of patients with POD who have been surgically treated for CRC. PA can be defined as one important preoperative risk factor that affect onset of POD . Identification of all preoperative risk factors and its correction represent best way of POD prevention.

Eryngium amethystinum L is a plant which grows in Balkan and Apennine peninsulas. The aerial parts, roots and fruits are used in ethnopharmacology of Italy and Western Balkan countries. Traditional preparations of E amethystinum were used in treatment of oedema, malaria and gastrointestinal diseases. Essential oils and extracts were isolated from aerial parts and roots of E amethystinum and examined by antimicrobial, antioxidative and cytotoxic assays. Gas-chromatography analysis showed predominance of germacrene D and spathulenol in essential oils of E amethystinum aerial parts, which have contributed to strong cytotoxic activity, while the methanolic extract exhibited strong antioxidative and antimicrobial activity. This article summarises all existing knowledge regarding E amethystinum, its chemical composition and pharmacological activity.

Background: According to laws on health care in Federation of Bosnia and Herzegovina, and AKAZ standards hospital health care includes a set of measures, activities and procedures, which are undertaken with the aim of diagnosing, treating and medically rehabilitating patients in appropriate inpatient health care institutions. Objective: The aim of this study was to explain influence of appropriate helath management standards for hospital healthcare activities and diagnostic services in the praxis. Methods: We used published books and papers with health management standards and also AKAZ standards for our description. Results and Discussion: Acute hospitalization according to the standards of the World Health Organization treats acute disease states or acute exacerbation of chronic diseases with a shorter duration of treatment. This type of hospitalization is carried out in: general, cantonal and clinical hospitals. General hospitals provide basic hospital care in general internal medicine, pediatrics, general surgery, gynecology and obstetrics and diagnostics for this level. Cantonal hospitals provide healthcare services in basic specializations, namely: pediatrics, pneumophthisiology, neurology, psychiatry, infectology, dermatovenerology, internal medicine, medical rehabilitation and physiatry, surgery, urology, orthopedics, otorhinolaryngology, ophthalmology, gynecology and obstetrics. Clinical centers provide services from a wide range of subspecialties, where the most modern diagnostic and therapeutic methods and equipment are used for diagnosis and treatment in these centers, and at the same time, clinical centers are also educational bases for individual clinical disciplines: cardiology, gastroenterology, nephrology, endocrinology, nuclear medicine, pneumophthisiology, hematology, neurology, psychiatry, pediatrics, infectology, dermatovenerology, oncology, angiology, neurosurgery, abdominal surgery, urology, thoracic surgery, orthopedics, reconstructive and plastic surgery, vascular surgery, ophthalmology, otorhinolaryngology, transplantology, cardiac surgery, children\'s surgery, toxicology, gynecology, obstetrics and emergency medicine. Conclusion: Health management aims to fulfill the task of meeting the needs of users of the health system in the process of providing services. The belief that good management is the key to the success of any company, school, development program, or health institution has led to the development of management as a field in recent years

Background: The basic model of a neural network is the physical structure of the human brain. The idea is simple: if a sufficiently powerful artificial network of synapses is created, the results of functioning similar to the human brain can be expected . Neural network or neurocomputer is one form of artificial intelligence system implementation, which represents a system consisting of a certain number of interconnected processors or nodes, or process elements that we call artificial neurons. Objective: The aim of this article was to draw attention to the necessity of taking about a detailed history of neural networks which are based on copying information processing in synaptic networks in neurons and synapses in the brain. Methods: The author searched scientific literature: the books and published papers deposited in index databases as source for description and explanation the architecture of a neural networks and its represents a specific connection of neurons into a single unit. Resuls and Discussion: The structure of a neural network differs in the number of layers. The first layer is called the input layer, and the last is the output layer, while the layers in between are called hidden layers. Most often, there are three of them. The first layer, or the input layer, is the only layer that receives data from the external environment, the next (hidden) layer forwards the relevant data to the third (output) layer. At the output of the third layer, we get the final result. More complex neural networks have more hidden layers. The layers are fully interconnected. Layers communicate by connecting the output of each neuron from the previous layer to the inputs of all neurons in the next layer. So, each node has several inputs and one output. The strength of the connections by which the neurons are connected is called the weight factor. Conclusion: In the past several books were written and several companies dealing with neurocomputers were founded. The computers were able to successfully adjust the weight coefficients, did not achieve significant practical results. Although neural networks have had an unusual history, they are still in an stage of development. Today, neural networks find a very wide range of applications in various practical areas.

Introduction/Objective. Introduction/Objective Following the failure of the single-wire technique in percutaneous coronary intervention (PCI) for chronic total occlusions (CTO), two principal anterograde escalation strategies are commonly employed: the parallel-wire technique and antegrade wire escalation (AWE). Despite their widespread use, comparative data on the procedural characteristics and long-term clinical outcomes of these strategies remain scarce. This study aims to compare the procedural parameters and long-term outcomes of the parallel-wire and AWE techniques after single-wire failure in CTO PCI. Methods. This retrospective, single-center study included patients who underwent successful CTO PCI between January 2018 and December 2023 using either the parallel-wire or AWE technique following single-wire failure. The primary endpoint was a composite of cardiac death, myocardial infarction, stroke, or target vessel revascularization (TVR). Secondary outcomes included procedure duration, fluoroscopy time, contrast volume, and total radiation dose. Median follow-up duration was 1222 days (IQR 580-1969 days). Results. Among 270 CTO PCI procedures, 112 (41.5%) required escalation: 90with AWE and 22 with the parallel-wire technique. Baseline clinical and angiographic characteristics were comparable. The primary composite outcome occurred in 14.4% of the parallel-wire group and 9.1% of the AWE group (p = 0.73). No significant differences were observed in individual clinical events. Procedure duration was longer (95.5 ? 43.6 vs. 77.0 ? 30.7 min; p = 0.064) and contrast volume higher (336.4 ? 113.3 vs. 271.6 ? 90.6 mL; p = 0.014) in the AWE group, with similar fluoroscopy time and radiation dose. No clinically or ?ngiographically significant complications occurred during the periprocedural period. Conclusion. Both AWE and parallel-wire techniques demonstrate comparable safety and efficacy following single-wire failure in CTO PCI. While procedural efficiency slightly favored the parallel-wire strategy, overall outcomes support either approach, pending further prospective validation.

Tionite is a solid residue formed during the production of titanium dioxide through the chloride process. This material is acidic and contains a high concentration of titanium, which makes it a potential secondary resource for titanium recovery. Instead of being disposed of as hazardous waste, tionite can be processed to extract valuable metals, particularly titanium. In this study, the recovery of titanium from tionite was carried out using an autoclave leaching method under high-pressure oxygen conditions. The presence of oxygen under pressure promotes the formation of titanium oxysulfate, which enhances the dissolution of titanium into solution. This approach enables selective leaching of titanium while limiting the dissolution of other unwanted elements. The leaching experiments were designed to explore optimal conditions for efficient titanium recovery, including temperature, pressure, and leaching time. The main objective of this research is to present a viable route for the valorisation of tionite by turning a hazardous acidic waste into a valuable source of titanium. This process contributes to waste reduction in the titanium dioxide industry and supports more sustainable resource management.

Introduction: Syncope is one of the most common reasons for seeking medical attention in the pediatric population. The underlying etiology ranges from benign causes to potentially life-threatening conditions. Objective: This cross-sectional retrospective study aimed to cardiologically evaluate children presenting with syncope and identify potential predictive parameters for cardiogenic syncope, the most dangerous type of syncope. Patients and Methods: Data from 100 children aged 6 to 18 years who presented with syncope were retrospectively collected from medical records at the Pediatric Clinic of the Clinical Center of the University of Sarajevo between January 1, 2021, and December 31, 2022. Binary logistic regression was used to examine the predictive significance of the studied parameters. Results: Of the 100 children with documented syncope, 71.0% were girls, with the peak incidence of syncope episodes occurring at age 15. There were no statistically significant differences in height, weight, or BMI between boys and girls. The most common cardiac diagnosis was sinus arrhythmia, while headache was the most frequent non-cardiac symptom. Seventy-three percent of patients experienced more than one syncope episode, with the highest percentage occurring at school. Prodromal symptoms were present in 87% of cases, whereas palpitations and chest pain prior to syncope were reported in 10% and 12% of cases, respectively. Among the 49 patients with abnormal ECG findings, 29% had sinus arrhythmia and 25% had incomplete right bundle branch block. The most common echocardiographic finding was mild pulmonary valve regurgitation, which is considered a physiological variant. Of all studied parameters, only EEG demonstrated significant predictive value for cardiogenic syncope (p = 0.035, EXP(B) = 2.99). Conclusion: EEG findings have predictive significance for cardiogenic syncope in children. A borderline EEG increases the odds of cardiogenic syncope by approximately threefold.

Background Biological mesh derived from porcine small intestinal submucosa (SIS) has a higher porosity and is more hydrophilic than tissue derived from bovine and cow dermal tissues. Therefore, we believe SIS mesh will lead to a milder inflammatory reaction than other, polypropylene and polypropylene-polydioxanone meshes, fewer adhesions, and less mesh shrinkage. Methods Ninety rats were divided randomly into three groups: in group 1, polypropylene mesh was implanted; in group 2, polypropylene-polydioxanone; and in group 3, the SIS mesh. The meshes were fixed intra-abdominally, in the upper part of the abdomen. Ten animals from each group were sacrificed on days 7, 28, and 60 after the implantation. Relaparotomy was performed, with a left paramedial incision and the adhesions formed were assessed according to the Surgical Membrane Study Group (SMSG) score, along with the percentage of shrinkage of the mesh, and any inflammation. Results There were no differences in terms of inflammatory reaction or the formation of adhesions between the meshes tested on the 7th day after implantation. However, the shrinkage of the SIS mesh was more expressed. On days 28 and 60, the SIS mesh caused less inflammatory reaction and formation of adhesions in relation to the other meshes tested. On day 60, there was no significant difference in the size of the meshes. Conclusion This study confirmed that, despite conflicting views on biological mesh, SIS mesh results in less inflammatory reaction, less adhesion formation, and a lesser degree of shrinkage, and can take its place in hernia repair.
