Aim Compare the efficacy of nebulized hypertonic saline and normal saline in the treatment of infants hospitalized for bronchiolitis. Methods This retrospective study was conducted at the Department of Pulmonology, Paediatric Clinic, Clinical Centre University of Sarajevo, covering the period from January 2015 to December 2019 and comprising 380 children aged between 1 and 12 months having bronchiolitis. One group received nebulized hypertonic saline (NHS, 3% NaCl)), and another group received nebulized normal saline (NNS, 0.9% NaCl). The control group did not receive any of these treatment options. Results There was no statistically significant difference between the treatment groups regarding length of hospital stay (LOS) and Clinical Severity Score (CSS) at admission and discharge as well as in oxygen therapy duration and antibiotic use, the duration of symptoms before hospital admission, frequency of nasal discharge, elevated temperature, dyspnoea, cough and dehydration. Conclusion The results of this study are consistent with several recent studies or meta-analyses and support the evidence against the use of NHS in hospitalized infants with mild or moderate bronchiolitis.

Aim This is the first research in Bosnia and Herzegovina presenting minimally invasive coronary artery bypass grafting surgery (MICS CABG) experience, advantages, and outcomes as compared to conventional surgery (OPEN CABG). Methods This retrospective cross-sectional study was conducted between January 2019 and November 2022 and included patients with indication for surgical revascularization. Results Among 237 patients, males predominated, 182 (76.7%), with a mean body mass index (BMI) of 28.4±3.9, median The Society of Thoracic Surgery Risk (STS) score of 1.55 (0.8, 4.0), short term STS score of 11.2 (6.8, 23.7), mean age of 64.8±8.7 (ranging 41-83) years, 122 (51.4%) underwent OPEN CABG and 115 (48.6%) MICS CABG. MICS CABG took less time (p<0.001; OPEN 3.5±0.8h; MICS 2.8±0.8h) and needed less mechanical ventilation (p<0.001, OPEN 17.3±11.9h; MICS 13.0±12.5h) than OPEN CABG. Even though there was no difference in hospitalization length between groups (OPEN (7.5±3.2), MICS (7.1±4.0)), patients receiving MICS (2.9±1.5) spent less time in the ICU (p=0.0013) than OPEN CABG (3.6±2.8). OPEN CABG used also more blood derivatives, red blood cells (OPEN 292 vs MICS 55), plasma (OPEN 270 vs MICS 86) and platelets (OPEN 71 vs MICS 28). Conclusion Patients undergoing MICS CABG in Bosnia and Herzegovina had less mechanical ventilation hours and less ICU duration compared to OPEN CABG even though the hospitalization duration was very similar. MICS CABG takes less time to be conducted, has fewer CPRs postoperatively, uses less blood derivatives including red blood cells, plasma and platelets.

Aim Examination of the effectiveness of STR loci in proving sibship of the Bosnian-Herzegovinian village of Orahovica and the formation of a "grey zone". Methods The probability of sibship was determined by calculating the likelihood ratio (LR) parameter for each of the 15 observed STR loci and for each of the pairs of relatives and non-relatives. Cumulative sibship index (CSI) was calculated for each of the pairs by multiplying the LR values of all 15 loci and obtained values are used as CSI limit for separating relatives from non-relatives. By creating a grey zone for local populations, an attempt was made to obtain a line of demarcation between siblings and non-siblings. Results An analysis of the origin of the respondents' relatives was performed, up to the level of sibship in the third generation. The results of the CSI for pairs of relatives from the village of Orahovica showed that the highest CSI value, and therefore the sibship probability was recorded among relatives from the village of Orahovica (CSI=534211727.203;SP=99.999999812%). On the contrary, incredibly low CSI value was recorded among non-relatives,ranging from CSI=0.0000001 to 0.5261434 (SP=0.000009999% to 34.475357951%). Conclusion For the threshold value CSI=1 and for CSI=3, this method determined sibship in 100% of pairs of relatives and the absence of biological sibship in 100% of pairs of non-relatives in the village of Orahovica. The STR system is proved to be a successful method in determining sibship or absence of sibship in small local populations.

Aim To determine the value of angles between the left coronary artery main trunk (LMT) and its branches, the anterior interventricular branch (LAD) and the circumflex branch (CX), and their possible relationship with the LMT length. Methods A total of 29 cadaveric hearts were used. The left coronary artery and its branches were dissected. The hearts were then classified according to the number of branches. The LMT length was measured with a digital gauge, and the LAD-CX angle, LMTLAD angle and LMT-CX angle with a manual goniometer. Results The average value of the LMT length was 9.0 mm (6.0-13.5). In 20 (68.97%) samples, the LMT was divided into two terminal branches. There was no statistically significant difference (p=0.321) in LMT length between the hearts with a bifurcation and without it. The average value of the LAD-CX angle was 89.0⁰ (74.5-93.0), with a statistically significant difference (p=0.020) comparing to hearts with trifurcation. The mean value of the LMT-LAD angle was 30.83±9.23⁰ and it was significantly lower (p=0.006) in the group of hearts with bifurcation compared to the group with trifurcation of the main trunk. Conclusion The LMT length shows great variability and is not related to the LAD-CX, LMT-LAD or the LMT-CX angle. Knowledge of the left coronary variation is essential in order to avoid misinterpretation of arteriogram.

Entre os vários problemas ambientais da contemporaneidade, a falta do reconhecimento da importância da botânica no nosso cotidiano, a ausência de sensibilização e a interação com a natureza são assuntos que a sociedade deve discutir. O presente trabalho, a fim de buscar e implantar possibilidades dentro da Educação Ambiental (EA), traz a proposta de formatação de uma trilha interpretativa conduzida e/ou autoconduzida de uma forma didático-pedagógica no campus da Universidade Estadual de Santa Cruz (UESC). A metodologia propõe uma dupla análise ao utilizar os métodos de Indicadores de Atratividades de Pontos Interpretativos (IAPI) e o Valor Turístico (Vtur). Foram realizadas visitas ao Horto Florestal da UESC e, com o auxílio do GPS Garmin etrex 10x e do aplicativo de celular TCpGPS, propomos um novo trajeto da trilha de 1.047 metros, com design circular e 10 pontos interpretativos. Diante disso, é possível afirmar que as metodologias utilizadas na proposta atingiram seu escopo ao possibilitar o conhecimento da flora local, das relações ecológicas, da acessibilidade, bem como do desenvolvimento de atitudes e valores diante do meio ambiente, de forma prática e sistematizada.

A sociedade experimenta uma forma de economia calcada em tecnologias de vigilância, que influenciou na conflagração de dados em camadas incomensuráveis. Nesse contexto, aparelha-se um desafio para a pesquisa científica, que deve acontecer obedecendo os padrões nacionais de proteção de dados pessoais. Para tanto, o presente trabalho objetiva estabelecer os padrões da LGPD para pesquisa científica, o contexto histórico que fundamenta a importância da ética na pesquisa e os perigos de uma regulamentação rígida da pesquisa através da LGPD que pode ferir direitos fundamentais. O método utilizado é o hipotético-dedutivo, com utilização de recursos bibliográficos e documentais. Em conclusão, a LGPD revela uma nova realidade para a pesquisa científica, transformando o pesquisador ou órgão de pesquisa em agentes de tratamento, com devidas responsabilidades no tratamento de dados pessoais dos humanos envolvidos na pesquisa científica. 

Aim To investigate the influence of the inclination and insertion of the cerebellar tentorium on the posterior cranial fossa (PCF) volume. Methods A retrospective, non-randomized study including 174 patients (117 females and 57 males) who underwent magnetic resonance imaging in the period from 31 December 2020 to 1 June 2021 under the indication (mostly headache) set by a competent ordinary. Acute or chronic intracranial events were not verified in the patients. Results The average value of the PCF volume was 138.93 cm3 and the slope of the tentorium was 44.15°. Comparing the volume of the PCF and the slope of the tentorium in males and females no significant difference was found. A correlation was found in the females age groups 18-24 and 45-54 years. Conclusion Understanding dimensions of the posterior cranial fossa morphometry has clear implications for reducing morbidity and mortality in surgery, especially in the case of applying lateral approaches and their variations.

Aim To examine a correlation of demographic characteristics of patients, preoperative modality of conservative therapy and timing on the postoperative outcome of patients six months after the operation. Methods A retrospective, non-randomized, clinical study involved 48 patients of different age and gender with a verified diagnosis of cauda equina syndrome (CES). The inclusion criteria were patients with CES caused by discus hernia. Observed research variables were age, gender, affected vertebral level, conservative modalities of perioperative therapy (nonsteroidal anti-inflammatory drugs - NSAIDs and physiotherapy), duration of symptoms, and outcome parameters (motor and sensory function, sphincter function of the urinary bladder and bowel). Results A statistically significant negative correlation was found between age and postoperative outcome (p<0.05). The affected vertebral level was positively correlated with the motor and sensory outcome (p<0.05). A positive correlation between the use of NSAIDs and the outcome was found (R=0.570; p<0.001), as well as a negative correlation with perioperative physiotherapy (R=-0.201; p= 0.001). Postponement of surgery was negatively correlated with outcome variables (p<0.001). Conclusion The results of the study bring new conclusions that were not previously observed. Possible new characteristics associated with the outcome of cauda equina syndrome were determined.

<p>In this paper, the influence of process parameters on the morphological properties of fine precipitated hydrate was examined. The research was conducted with the aim of synthesizing fine precipitated aluminum hydroxide from the aluminate solution obtained by the Bayer process. Fine precipitated hydrates obtained in this way are mostly used in the non-metallurgical industry. The synthesized fine precipitated hydrate should comply with certain quality requirements such as granulometry (average particle diameter), purity, specific surface area, whiteness, etc. This paper shows the influence of certain technological parameters, namely the initial precipitation temperature, the amount and specific surface area of the seed, the influence of the NaOH/Al(OH)3 molar ratio on the characteristics of the synthesized fine precipitated hydrate in terms of the specific surface area, mean diameter and morphology of the obtained particles.</p>

Significance The extent and pace of the transition from our current fossil fuel-based economy to one based on renewable energy will strongly depend on the availability of bulk energy storage solutions. Herein, we investigate one such candidate technology, using chemical precursors which are inexpensive, abundant, and widely available, specifically cement, water, and carbon black. The energy storage capacity of these carbon-cement supercapacitors is shown to be an intensive quantity, and their high rate capability exhibits self-similarity. These properties point to the opportunity for employing these structural concrete-like supercapacitors for bulk energy storage in both residential and industrial applications ranging from energy autarkic shelters and self-charging roads for electric vehicles, to intermittent energy storage for wind turbines.

Eutrophication is an important threat to aquatic ecosystems world-wide, and reliable identification of areas vulnerable to phosphorus (P) losses from diffuse sources is essential for high efficiency of mitigation measures. In this three-step study we investigated (i) relationships between the agronomic (Olsen-P and P-AL) and environmental soil P tests (P-CaCl2) with molecular techniques (31P NMR and XANES) followed by (ii) rainfall simulation experiment on topsoil lysimeters and (iii) comparison to long-term field measurements of water quality. Soil samples were collected from seven sites indicated to be vulnerable to nutrient losses due to underlying geology. High P release correlated to standard agronomic P tests (Olsen P, r = 0.67; and P-AL, r = 0.74) and low P sorption capacity (r = − 0.5). High content of iron-bound P compounds indicated more labile P and higher release of dissolved P (r = 0.67). The leaching experiment showed that three out of four soils with high initial soil P status had both higher P leaching concentrations before fertilization (0.83–7.7 mg P l−1) compared to soil with low initial soil P status (0.007–0.23 mg P l−1), and higher increase in P concentrations after fertilization. Higher soil P sorption capacity reduced P leaching losses. Finally, long-term monitoring data show no significant trends in P losses in a field with low initial P content and moderate P fertilization rates whereas high and over time increasing P losses were recorded in a field with high initial soil P content and repetitively high P fertilization rates.

Objective: This study aims to compile the latest information concerning workplace stretching regimens and to give a panoramic view of their effectiveness in reducing work-related Musculoskeletal disorders (MSDs). Methods: Searching MEDLINE, Embase, CINAHL, PEDro, Web of Science, Scopus, Google Scholar, SPORTDiscus and PubMed databases from 2010 to 2022 found 723 eligible studies, based on predefined inclusion criteria. Results: In the review, 14 included studies recruited subjects aged 18 years, with males (n=813), females (n=5141), and some research did not identify gender (n=3). The included studies were of both high (n=6) and low quality (n=8). Seven studies revealed stretching exercises to be an effective and safe non-pharmacological intervention for MSDs, and one study included an active control group observed better improvement in the treatment group. Four trials showed a significant effect from stretching exercises as a stand-alone treatment. Three studies revealed that stretching exercises had a meaningful and major effect on MSDs complaints, while two studies reported no significant results when utilizing Anti-fatigue mats in addition to stretching. Conclusion: The current study indicated that stretching exercises are a crucial and useful technique for preventing and treating pain and function in Work-related MSDs affecting the neck, shoulder, back, etc. Workplace/ergonomic changes can enhance the results of stretching exercises.

Essential oils are mixtures of potent compounds with biological effects, such as those with antioxidant, antimicrobial, antitumor and/or anti-inflammatory effects. In this paper, the antioxidant and antimicrobial activity of essential oils of different types of commercial pepper was tested. Essential oils are prepared by hydrodistillation. Polyphenol content, reduction potential and DPPH radical inhibition were analyzed. Antimicrobial activity was tested on reference strains using the diffusion technique. The analysis showed that the essential oil of black pepper has a significantly higher antioxidant potential compared to the essential oils of green and white pepper. High antimicrobial activity was also found for the black pepper essential oil sample, except in the case of Pseudomonas aeruginosa.
