This short biography traces the life and medical activities of Rosalie Sattler, née Feuerstein (1883-19??), who was employed as an official female physician at the Austro-Hungarian (AH) provincial public health department in Sarajevo from 1914-1919. Born in 1883 into a Jewish middle-class family in Chernivtsi (then Czernowitz), Ukraine, in Bukovina, the easternmost province in Austria, Feuerstein moved to Vienna in 1904 to study medicine. After earning her MD from Vienna University in 1909, she started her career as an assistant physician at the Kaiser Franz Josef Hospital in Vienna. In spring 1912, Feuerstein moved to Sarajevo to work as an intern at the local provincial hospital (Landeskrankenhaus). In the same year, she married AH district physician Moritz Sattler (1873-1927) in Vienna. In 1914, Sattler-Feuerstein successfully applied to be an AH official female physician in Bosnia. She was an employee of the provincial public health department in Sarajevo and never functioned as an official female physician in the sense of the relevant AH service ordinance. After the collapse of the monarchy, Sattler-Feuerstein continued to be employed as an official female physician of the Kingdom of Serbs, Croats, and Slovenes. She resigned from service in 1919 and established herself as a private general practitioner in Sarajevo with her husband, who had also resigned as an official physician and started to practice privately at that point. Widowed in 1927, she left Sarajevo for an unknown destination, likely in 1938-1939, and vanished from historical records. CONCLUSION: Rosalie Sattler-Feuerstein (1883-19??) came to Bosnia as the eighth AH official female physician and worked as an employee of the AH provincial public health department in Sarajevo from 1914-1919, after which she practiced as a private physician in Sarajevo for more than 25 years.

Athletes who train in public places in urban and rural areas are just as attacked and injured by dogs of known owners as they are by dogs with no owners, in a relatively equal proportion. The largest number of bites occurs in the summer, what makes up half of all bites, just when sports activity is most pronounced. Athletes who are most often exposed to potential attacks and bites are cyclists, long-distance athletes, marathon runners, recreational athletes, etc. both during training and competitions. Off-road cyclists are at a significantly higher risk of dog attacks because cycling takes place off-road, that is, away from urban areas. Dog attacks can adversely affect the psycho-physical readiness of athletes. In Bosnia and Herzegovina there have been no cases of injuries to athletes recorded by competent medical institutions or umbrella sports associations. It is necessary to work on more efficient administration (registration and recording of attacks and bites of dogs). It is of utmost importance to educate athletes on dog behaviour, the reasons for their aggressive behaviour and causal mechanisms of dog attacks as well as the first aid education, what can have a great impact on reducing further complications.

Aim To identify predictive factors related with noninvasive ventilation (NIV) failure that are not based on the patient's respiratory status or acid base gas analyses in COVID-19 critically ill patients, and to create a predictive model of NIV failure. Methods A total of 73 COVID-19 critically ill patients who developed acute respiratory failure and underwent NIV were divided into two groups: Group 1, patients who required endotracheal intubation and invasive mechanical ventilation after NIV and Group 2, patients with successful weaning from NIV. Demographic data, clinical symptoms and signs, clinical index and scores, duration indicators and laboratory data were analysed. Predictive factors of NIV failure were assessed using univariate and multivariate regression analyses followed by the receiver operating characteristic (ROC) curve. Results In the Group 1 (NIV failure) there were 54 (73.97%) patients. Predictive factors for NIV failure were: the presence of dyspnoea on the day of admission at hospital (p<0.05; sensitivity 44.40%; specificity 84.20%), higher radiographic assessment of lung oedema score (RALES) on the day of starting NIV (p<0.009; sensitivity 70.40%; specificity 73.75%), higher length of NIV (p<0.014; sensitivity 48%; specificity 84.10%) and higher urea on the day of starting NIV (p<0.004; sensitivity 70.44%; specificity 73.72%) Conclusion NIV treatment in COVID-19 critically ill patients has a high failure rate. In addition to respiratory parameters, dyspnoea, higher RALES, higher length of NIV and increased urea value could predict NIV failure. These factors should be considered in treatment decision making.

Aim To analyse demographic data, clinical symptoms and signs, laboratory data and comorbidities in patients with COVID-19 pneumonia admitted to the intensive care unit (ICU), mechanically ventilated with fatal outcome. Methods Medical records of 92 patients were retrospectively analysed. Demographic data, clinical symptoms and comorbidities were collected on the day of hospital admission. Clinical signs and laboratory data were collected on the day of hospital admission (T1), on the day of starting non-invasive ventilation (T2), and on the day of starting invasive ventilation (T3). Results Average age of the patients was 60.05 years. Patients over 50 years of age, 71 (77.1%) (p=0.000), and males, 62 (67.4%; p=0.001) were predominant. The most common patient symptoms were exhaustion, myalgia, dyspnoea and cough. Hyperthermia was recorded on the day of hospital admission. Tachycardia, hyperglycaemia, hypoxemia were recorded at all observed study times. The most common comorbidity was hypertension arterialis with a very strong correlation with fatal outcome, followed by diabetes mellitus and chronic heart disease that were moderately correlated with fatal outcome. Conclusion The treatment of COVID-19 patients in ICU with mechanical ventilation has a high failure rate. Demographic data, clinical symptoms and signs as well as accompanying comorbidities can be a significant component in making decisions about diagnostic-therapeutic procedures.

Abstract Hearing aids continue to acquire increasingly sophisticated sound-processing features beyond basic amplification. On the one hand, these have the potential to add user benefit and allow for personalization. On the other hand, if such features are to benefit according to their potential, they require clinicians to be acquainted with both the underlying technologies and the specific fitting handles made available by the individual hearing aid manufacturers. Ensuring benefit from hearing aids in typical daily listening environments requires that the hearing aids handle sounds that interfere with communication, generically referred to as “noise.” With this aim, considerable efforts from both academia and industry have led to increasingly advanced algorithms that handle noise, typically using the principles of directional processing and postfiltering. This article provides an overview of the techniques used for noise reduction in modern hearing aids. First, classical techniques are covered as they are used in modern hearing aids. The discussion then shifts to how deep learning, a subfield of artificial intelligence, provides a radically different way of solving the noise problem. Finally, the results of several experiments are used to showcase the benefits of recent algorithmic advances in terms of signal-to-noise ratio, speech intelligibility, selective attention, and listening effort.

The SARS-CoV-2 (COVID-19) pandemic has emerged as one of the greatest problems of the 21st century worldwide. Efforts to fight this pandemic require a global co-operation and a multidisciplinary approach. An application of information and communication technologies (ICT) to a great degree contributes to fighting the pandemic as these technologies are one of the key services that assist patients, researchers, health institutions and other interested parties in different activities in an effort to fight the pandemic and its consequences. The present paper presents the features of certain mobile applications (apps) that are being used for different purposes such as: tracking patients, COVID-19-related warnings, keeping tracks of statistical data, organising life and business, etc. Aside from presenting the features of a certain number of applications, a review of technologies used for the development of these applications will also be presented. Furthermore, the paper addresses certain challenges that come along with the mobile technologies applications and offers suggestions for future research.

OBJECTIVE To present a rare disease, and to point out that clinical manifestations treated for a long period of time without an adequate response to therapy may be a manifestation of a rare disease. CASE REPORT We present the case of a 3-year-old girl who had been drinking a large amount of water for the previous ten days with frequent urination, and who experienced the worsening of symptoms of scalp dermatitis that had been treated for a year without success. Physical examination revealed a maculopapular rash on the scalp, neck and both ear shells, and exophthalmos of the right eye with periorbital edema. Magnetic resonance imaging of the orbits showed extensive lesions of the skull bones. Further diagnostic evaluation revealed similar lesions in other bone structures. Biopsy of the affected region, microscopic and immunohistochemical analysis led to diagnosis of Langerhans cell histiocytosis. CONCLUSION Langerhans cell histiocytosis mostly occurs in the first three years of life. The incidence is 4-5 patients per million children under 15 years of life. The clinical presentation is highly variable, and can range from isolated, self-healing skin and bone lesions to life-threatening multisystem diseases. Due to the diverse clinical picture, that is often unrecognized, these patients are often referred to other specialists, resulting in the treatment of individual symptoms rather than the underlying disease.

Aim To investigate knowledge, attitudes and practice towards COVID-19 among selected population. Methods An anonymous online questionnaire based on a Chinese study was distributed via online social media platforms among general population of Bosnia and Herzegovina, Germany, India, Kosovo and Romania. Results In total 1032 subjects, predominately females, 615 (59.6%) with a mean age of 31.23±12.94 years, single, 705 (68.3%), with high school degree or lower, 469 (45.4%), students, 528 (51.1%) and living in an urban environment, 824 (79.8%), have completed the survey. The median knowledge score was 10.0 (range 0-12). Being male (β: -0.437; p=0.003) and older (β: -0.028; p<0.001) were associated with lower knowledge scores, while being single (β: 1.026; p<0.001) and mental labour employee (β: 0.402; p=0.032) were associated with higher knowledge scores. The vast majority of subjects had not visited crowded places, 630 (61.0%) and wearing masks when they were going out, 928 (89.9%). Being female (OR=0.731; p=0.022), having higher knowledge scores (OR=0.929; p=0.017) and being a mental labour employee (OR=0.713; p=0.031) decreased the exposure to crowded places. High school or lower education level (OR=0.616; p=0.024) decreased the action of wearing a mask in public places, while higher knowledge scores (OR=1.112; p=0.013) increased it. Conclusion Our study suggests that residents of the selected regions have had good knowledge, pessimistic attitudes and relatively appropriate practices towards COVID-19 during the second wave of the outbreak.

Aim To explore patient's awareness and appliance of the fasting state requirements for blood sampling. Methods This observational survey was performed at the Department of Medical Biochemistry and Immunology Diagnostics, Cantonal Hospital Zenica, from June to July 2019. An anonymous questionnaire was conducted on 200 consecutive outpatients older than 18, who were admitted to the laboratory for routine blood testing. Results A total of 134 (67%) patients were informed that they needed to be at fasting to perform laboratory tests. Patients were mostly informed by a requesting physician or a nurse, 68 (50.8%), and by other patients, members of the family and friends, 58 (43.3%); only seven (5.2%) patients were informed in the laboratory. A total of 75 (37.5%) patients arrived to the laboratory properly prepared. Conclusion Most patients were not well informed about fasting state requirements for blood sampling and consequently they were not adequately prepared for laboratory tests. Laboratory should establish updated fasting recommendations available to patients and healthcare professionals, and conduct continuing education of patients and health care staff.

Aim To investigate the relationship between preoperative level of serum albumin in patients with colorectal cancer (CRC), stage of CRC and postoperative complications. Methods This cross-sectional retrospective study was conducted at the Clinic for General and Abdominal Surgery of the University Clinical Centre Sarajevo (UCCS). A total of 107 patients surgically treated for CRC in the period between 2013 and 2018 were enrolled in this study and divided into two groups: with hypoalbuminemia (group A) and without hypoalbuminemia (group B). Results The average level of albumin in group A was 29 (25-32) g/L versus 39 (37-41) g/L in group B (p<0.05). The average length of hospital stay in group A was 18 (13-25) days, and in group B 14.5 (12-21) days. Patients with hypoalbuminemia (group A) had wound dehiscence more often and more re-interventions compared to group B (p<0.05). Binary logistic regression found that serum protein, albumin and globulin levels were not statistically significant in the prediction of CRC stadium or postoperative complications (p>0.05). Conclusion Study results show that preoperatively measured levels of serum albumin are not associated with the stage of colorectal cancer and cannot serve as predictors for postoperative complications.

Abstract Digital workplace transformation goes beyond the adoption or non-adoption of technologies – it has far deeper effects in the context of re-designing a workplace. Future digital work implies not only a change of tools used in work activities, but it also often changes the very nature of the working activities and processes. Psychological needs of employees are important in this context: the need for autonomy, competence, and relatedness which affect the employees' motivation to accept the future workplace. More specifically, if employees have expectations that digital environment will enable them to accomplish better performance, bigger satisfaction and personal well-being more easily, they will be more motivated to support digital transformation. Thus, in our study we aim to investigate whether employee involvement, well-being and support to digital work foster digital transformation of the workplace. In doing so, we close the existing gap in literature and confirm that interpersonal relatedness in digital work environment has a significant influence on employees' performance and well-being. This, in turn, increases employees’ intentions to support digital workplace transformation. We believe this study will help pre-digital organizations to rethink their strategies according to employee involvement to respond to the challenges of digital transformation. The study also encourages scholars to investigate whether and how those factors are shaped differently due to COVID-19 pandemic context.
