Impact of risk factors, early rehabilitation and management of lymphedema associated with breast cancer: a retrospective study of breast Cancer survivors over 5 years.

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a potentially disabling and often irreversible consequence of breast cancer treatment, caused by the mechanical incompetence of the lymphatic system, resulting in reduced drainage capacity and functional overload due to an excessive volume of interstitial fluid surpassing the system's transport capacity in the arm. We wanted to determine the impact and explore the differences in independent risk factors for the occurrence of BCRL; incidence of BCRL over a five-year period at the Institute of Oncology Vojvodina in Sremska Kamenica and to answer the research question regarding the influence of the prehabilitation program on the overall incidence of BCRL during the observed five-year period. METHODS: From 2014 to 2018, a retrospective study was conducted at the Institute of Oncology of Vojvodina in Sremska Kamenica, analyzing female patients who had undergone breast cancer surgery. RESULTS: The study included 150 breast cancer patients who developed secondary lymphedema following surgery with the mean age of 59.2 ± 11.3 years. Fluctuations in hospitalization rates were observed over the five-year period, with the highest number of admissions in 2014 (24.0%) and a decline in 2018 (14.0%). The most common surgical procedure performed was left quadrantectomy (24.0%), followed by right quadrantectomy (20.0%) and left amputation (15.3%). The mean number of removed lymph nodes was 15.2 ± 6.1, with no statistically significant association between the number of removed lymph nodes and the manifestation of secondary lymphedema. The severity of secondary lymphedema varied based on patient age, with a higher incidence of moderate and severe lymphedema observed in patients aged 61 years and older. Patients who underwent radical surgery were more likely to experience severe lymphedema compared to those who had conservative surgery, although this difference was not statistically significant. CONCLUSION: In our study, the type of surgery, elapsed time since surgery, and the number of removed lymph nodes were not influencing factors for the occurrence of BCRL. However, concerning its severity, a greater number of systemic therapy modalities combined with radiotherapy were associated with a more frequent occurrence of mild and moderate BCRL. Also, the severity of BCRL varied among different age groups, with a higher incidence of moderate and severe lymphedema observed in patients aged 61 years and older. Ultimately, improving the quality of life for individuals affected by secondary lymphedema remains a crucial goal in the field of oncology.

Assessment and Application of the Hear Score in Remote Emergency Medicine Outposts in Bosnia and Herzegovina.

Background and Objectives. In emergency departments, chest pain is a common concern, highlighting the critical importance of distinguishing between acute coronary syndrome and other potential causes. Our research aimed to introduce and implement the HEAR score, specifically, in remote emergency outposts in Bosnia and Herzegovina. Materials and Methods. This follow-up study conducted a retrospective analysis of a prospective cohort consisting of patients who were admitted to the remote emergency medicine outposts in Canton Sarajevo and Zenica from 1 November to 31 December 2023. Results. This study comprised 103 (12.9%) patients with low-risk HEAR scores and 338 (83.8%) with high-risk HEAR scores, primarily female (221, 56.9%), with a mean age of 63.5 ± 11.2). Patients with low-risk HEAR scores were significantly younger (50.5 ± 15.6 vs. 65.9 ± 12.1), had fewer smokers (p < 0.05), and exhibited a lower incidence of cardiovascular risk factors compared to those with high-risk HEAR scores. Low-risk HEAR score for prediction of AMI had a sensitivity of 97.1% (95% CI 89.9-99.6%); specificity of 27.3% (95% CI 22.8-32.1%); PPV of 19.82% (95% CI 18.67-21.03%), and NPV of 98.08% (95% CI 92.80-99.51%). Within 30 days of the admission to the emergency department outpost, out of all 441 patients, 100 (22.7%) were diagnosed with MACE, with AMI 69 (15.6%), 3 deaths (0.7%), 6 (1.4%) had a CABG, and 22 (4.9%) underwent PCI. A low-risk HEAR score had a sensitivity of 97.0% (95% CI 91.7-99.4%) and specificity of 27.3% (95% CI 22.8-32.1%); PPV of 25.5% (95% CI 25.59-28.37%); NPV of 97.14% (95% CI 91.68-99.06%) for 30-day MACE. Conclusions. In conclusion, the outcomes of this study align with existing research, underscoring the effectiveness of the HEAR score in risk stratification for patients with chest pain. In practical terms, the implementation of the HEAR score in clinical decision-making processes holds significant promise.

OHCA in Bosnia and Herzegovina: Before and During the COVID-19 Pandemic.

Background: Out-of-hospital cardiac arrest (OHCA) refers to the cessation of mechanical cardiac activity outside healthcare facilities which requires prompt intervention and intensive resuscitative efforts. The COVID-19 pandemic has caused significant disruptions to OHCA systems-of-care, adversely affecting every component of the chain of survival. Objective: The objective of this study was to examine the potential impacts of the COVID-19 pandemic on OHCA events, to draw comparisons between the period before and during the COVID-19 pandemic. Methods: This cross-sectional study encompassed data pertaining to all OHCA incidents attended to by the Emergency Medical Service of Canton Sarajevo, covering the period from January 2017 to December 2022, before and during the COVID-19 pandemic. Results: During observed period, a total of 1418 [796 (56.1%) before and 622 (43.9%) during COVID-19 pandemic] OHCA events have occurred in Canton Sarajevo of which 297 (20.9 %) [180 (12.7%) before and 117 (8.2%) during COVID-19 pandemic] obtained ROSC. After a 30-day period following the ROSC) it was observed that the predominant outcome, accounting for 181 (12.7%) [106 (7.4%) before and 75 (5.2%) during COVID-19 pandemic] of cases, was a complete recovery. An examination before and during COVID-19 pandemic revealed a decline in OHCA during the year 2021 and 2022 when COVID-19 pandemic was at its highest in the country Being younger, quicker EMT response time and individuals with the initial rhythm of VF or VT were significantly associated with obtaining ROSC (p<0.05). Only 48 (3.3%) of 1418 OHCA events were assisted by bystanders There was no report of AED usage. Conclusion: In conclusion, our investigation highlights the impact of the COVID-19 pandemic on OHCA events in Canton Sarajevo, revealing a decrease in OHCA incidence and a reduction in cases achieving ROSC. Notably, EMT response time was shorter during the pandemic.

Comparison between conventional open-heart valve surgery and minimally invasive valve replacement surgery regarding the length of hospital stay and usage of blood derivates: insights from a single-centre, single-surgeon study conducted in Bosnia and Herzegovina.

Aim To analyse the correlation between different surgical methodologies employed in valve diseases treatment and their subsequent impact on the duration of hospitalization. Methods This retrospective study conducted at the Clinical Centre of the University of Sarajevo analysed medical records of 163 valve disease patients treated between January 2019 and November 2022. The patients were divided into two groups: 77 had openheart valve surgery and 86 underwent minimally invasive cardiac surgery (MICS). Results The mean duration of the surgical procedures was 3.9±1.3 hours, with conventional open-heart surgery requiring an average of 3.6±1.1 hours and minimally invasive cardiac surgery (MICS) procedure 4.2±1.5 hours. No substantial disparities were found in the total length of hospitalization between the two groups, as both conventional (8.2±4.5 days) and MICS (8.7±7.0 days) demonstrated similar duration. Similarly, the total duration of intensive care unit (ICU) stay displayed similarity, with conventional surgery patients staying an average of 3.9±2.8 days and MICS patients of 4.2±4.1 days. The pattern of blood transfusion and fresh-frozen plasma usage revealed higher rates in the conventional valve surgery group comparing to the MICS group. Conclusion Minimally invasive valve surgery, despite slightly longer operative times, resulted in lower blood transfusion requirements and comparable hospitalization and ICU stay.

The Role of Resilience in the Relationship between Sociodemographic, Clinical Characteristics, and Social Support among Breast Cancer Patients in Serbia.

BACKGROUND: The management of breast cancer treatments within the limitations of family, social, and professional life is emotionally burdening and negatively affects physical, psychological, and social well-being, reducing the overall quality of life of patients and their families. METHODS: This cross-sectional descriptive-analytical study was conducted from March to August 2023 at the "Dr. Radivoj Simonovic" General Hospital in Sombor. A total of 236 breast cancer patients participated in this study. The research was conducted using the following instruments: a questionnaire on sociodemographic and clinical characteristics of patients, the Berlin Social-Support Scales-for assessing social support-and the Connor-Davidson Resilience Scale-for assessing resilience. This study aimed to determine the predictors and levels of social support and resilience of breast cancer patients. We also wanted to examine whether resilience is a mediator between patients' sociodemographic and clinical characteristics and levels of social support. RESULTS: The total average value of social support was 3.51 ± 0.63, while on the resilience scale, the respondents achieved a total average score of 52.2 ± 9.63. Perceived and actually received social support of breast cancer patients were positively correlated with resilience [p < 0.01], while no statistically significant correlations were found for the need for support and satisfaction. The sets of predictors can significantly predict their effects on all types of perceived social support (emotional social support: 9%; perceived instrumental social support: 9%) and all types of received social support (actually received emotional social support: 8%; actually received instrumental social support: 7%; actually received informational social support: 8%). There is a potential mediating role of resilience in relation to sociodemographic factors, clinical characteristics, and the need for support. CONCLUSION: This study confirms that a strong connection exists between social support and resilience. However, the analysis did not confirm the mediating role of resilience between the sociodemographic and clinical characteristics on the one hand and social support on the other.

HEART Score and Its Implementation in Emergency Medicine Departments in the West Balkan Region-A Pilot Study.

BACKGROUND: Chest pain represents a prevalent complaint in emergency departments (EDs), where the precise differentiation between acute coronary syndrome and alternative conditions assumes paramount significance. This pilot study aimed to assess the HEART score's implementation in West Balkan EDs. METHODS: A retrospective analysis was performed on a prospective cohort comprising patients presenting with chest pain admitted to EDs in Sarajevo, Zenica, and Belgrade between July and December 2022. RESULTS: A total of 303 patients were included, with 128 classified as low-risk based on the HEART score and 175 classified as moderate-to-high-risk. The low-risk patients exhibited younger age and a lower prevalence of cardiovascular risk factors. Laboratory and anamnestic findings revealed higher levels of C-reactive protein, ALT, and creatinine, higher rates of moderately to highly suspicious chest pain history, a greater number of cardiovascular risk factors, and elevated troponin levels in moderate-to-high-risk patients. Comparatively, among patients with a low HEART score, 2.3% experienced MACE, whereas those with a moderate-to high-risk HEART score had a MACE rate of 10.2%. A moderate-to-high-risk HEART score demonstrated a sensitivity of 91.2% (95%CI 90.2-93.4%) and specificity of 46.5% (95%CI 39.9-48.3%) for predicting MACE. CONCLUSION: This pilot study offers preliminary insights into the integration of the HEART score within the emergency departments of the West Balkan region.

Magnetic resonance morphometry of the lumbar spinal canal in Zenica - Doboj Canton in Bosnia and Herzegovina.

Aim To investigate morphometric determinants of lumbar canal in patients treated in Cantonal Hospital Zenica, and their variation according to gender. Methods Morphometry of lumbar spinal canal was assessed in 52 patients treated at the Department of Neurosurgery of Cantonal Hospital Zenica in the period between September 2022 and November 2022. Data were collected retrospectively: anteroposterior and transverse diameter of lumbar vertebrae and intervertebral discs, as well as anteroposterior diameter of the spinal canal. Results Gender appeared to be an important morphometric determinant, since it significantly differed when it comes to lumbar vertebral anteroposterior and transverse diameter, being mostly larger in males. Conclusion This study increases anatomical knowledge of the vertebras and spinal canal of the lumbar region. Therefore, the measured dimensions of the lumbar vertebrae and spinal canal could be used as a baseline point for evaluation of patients presenting with low back pain and potential spinal canal stenosis.

Lipid status and carotid intima-media thickness in patients with end-stage renal disease.

Aim To assess morphological characteristics of carotid blood vessels in uremic patients before to the initiation of the dialysis treatment, and corelate data with various dialysis therapy modules. Methods The study included 30 patients with end-stage renal disease (ERDS) prior to commencing dialysis, 30 patients treated with haemodialysis and 30 patients treated with continuous ambulatory peritoneal dialysis. The control group consisted of 15 subjects with normal kidney function (eGFR>60ml/min). Carotid intima-media thickness (CIMT), as well as lipid status values (cholesterol, triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A, apolipoprotein B) were evaluated. Results The significant difference in CIMT was detected between the control and haemodialysis groups (p<0.001), and between the control and the peritoneal dialysis group (p=0.004). In patients in the predialysis group, CIMT was influenced by cholesterol (p=0.013), HDL (p=0.044), LDL (p=0.001) and ApoB (p=0.042) values. A significant difference in CIMT was proved between the haemodialysis and predialysis group of patients (p<0.001). The only variable from the patient's lipometabolic profile significantly associated with the change in IMT in uremic patients was HDL. A significant difference was found in the average value for systolic blood pressure (p<0.001) and diastolic blood pressure (p=0.018) in patients before starting the dialysis treatment compared to patients treated with other dialysis methods. Conclusion Patients on haemodialysis treatment had a significantly greater CIMT, which is in relation with a higher cardiovascular risk.

Minimally invasive coronary artery bypass (MICS CABG) in Bosnia and Herzegovina: a single centre, single surgeon cohort experience.

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.

Fear, Anxiety and Depression among Bosnia and Herzegovina Citizens during the Third Wave of COVID-19.

Objective: During the COVID-19 pandemic, fear, anxiety, and depression have become global concerns among the wider public. This study aimed to examine the occurrence of fear, anxiety and depressive symptoms associated with COVID-19, to assess influencing factors that lead to the development of these mental health conditions and to examine any changes in the mental health patterns of the society since the initial study a year ago in Sarajevo, Bosnia and Herzegovina. Method : An anonymous online survey based on Fear of COVID-19 Scale (FCV-19S), General Anxiety Disorder-7 (GAD-7) and Patients Health Questionnaires (PHQs) was conducted in the general population of Sarajevo in Bosnia and Herzegovina. Results: From 1096 subjects, 81.3% were females, 33.8% had a high school degree, 56.4% were married, 53.4% were engaged in intellectual labor, 42.3% experienced fear, 72.9% had anxiety symptoms and 70.3% had depressive symptoms during the COVID-19 pandemic and their mean age was 35.84 ± 10.86. Half (50.1%) of the subjects were COVID-19 positive and 63.8% had COVID-19 symptoms when responding to the questionnaire. Experiencing COVID-19 related fear (OR = 1.972) and having moderate to severe depressive symptoms (OR = 9.514) were associated with the development of mild to severe anxiety symptoms during the COVID-19 pandemic, which were in turn associated with the development of moderate to severe depressive symptoms (OR = 10.203) and COVID-19 related fear (OR = 2.140), respectively, thus creating a potential circulus vicious. COVID-19 positive subjects (OR = 1.454) were also more likely to develop mild to severe anxiety symptoms during the COVID-19 pandemic. Conclusion: In conclusion, the prevalence of fear, anxiety symptoms and depressive symptoms rose dramatically since the beginning of the COVID-19 pandemic in Bosnia and Herzegovina. They were interconnected and were significantly associated with age, gender, marital status and COVID-19 status. Therefore, an urgent mental health intervention is needed for the prevention of mental health problems.

Cervical Cancer Prevention Knowledge (Cckp-64) among Female Students in Novi Sad, Serbia during COVID-19 Pandemic.

Cervical cancer is a significant global health concern affecting young women, with over 500,000 new cases reported annually. This questionnaire-based study aimed to evaluate the knowledge of cervical cancer prevention among female students at the University of Novi Sad during the COVID-19 pandemic using the Cervical Cancer Knowledge Prevention-64 (CCKP-64) tool. The study sample consisted of 402 predominantly 20-22-year-old female students from either social or technical science faculties in urban environments. Results revealed that out of the 402 female students involved in the study, most had a good general knowledge of primary prevention of cervical cancer, with a correct answer rate ranging from 29.9 to 80.6%. On the contrary, only 63.4% of female students have heard about the vaccine against cervical cancer; 52.0% know that the vaccine exists in Serbia; and 31.8% know where to get vaccinated. Only a small proportion of students (9.7%) have encountered cervical cancer among their relatives/friends and think that the disease could affect them in the future (25.4%). Older students (>26 years) generally (p < 0.05) had better knowledge regarding distressing symptoms of cervical cancer, cytological examination and secondary prevention; however, it was also noted that a significant percentage of this age group reported not having received vaccinations (53.0%, p = 0.001). This study underscores the need for increased awareness and education about the HPV vaccine and secondary prevention among young women in Serbia. Future research should investigate knowledge and attitudes toward cervical cancer prevention in diverse populations to develop effective interventions and strategies. These findings have implications for public health policies in Serbia to promote cervical cancer prevention among young women.

COVID-19 vaccination knowledge, attitudes and practices among the general population of Romania during the third wave of COVID-19 pandemic.

Objective: Romania began its COVID-19 immunization programme with approved vaccinations in three stages, as follows: The first step of vaccination is for health and social professionals, the second stage is for high-risk persons and the third stage is for the remainder of the general public. This study aims at assessment of knowledge, attitude and practice towards COVID-19 and vaccination against COVID-19 in the Romanian population during the third wave of the pandemic. Methods: This cross-sectional study was based on a Bosnian and Herzegovinian study on COVID-19 vaccination during the country's third wave of COVID-19 pandemic. Results: Our study sample, dominantly female (629; 61.0%), with a bachelor's degree (734; 71.2%), either single (539; 52.3%) or in a relationship (363; 35.2%), engaged in intellectual labour (910; 88.3%) and living in an urban environment (874; 84.8%) with a mean age of 25.07 ± 8.21 years, 294 (28.5%) people with COVID-19 symptoms and 86 (8.3%) were tested COVID-19 positive, had a mean knowledge score of 16.38 ± 4.0 with correct answer rates on questions ranging from 30.1% to 88.2%. Being single (odds ratio = 3.92, p = 0.029) or in a relationship (odds ratio = 3.79, p = 0.034), having a bachelor's degree and higher (odds ratio = 1.61, p = 0.006) and being COVID-19 tested (odds ratio = 1.82, p < 0.001) were associated with higher knowledge test scores. Our sample had relatively optimistic attitudes towards final COVID-19 disease containment (712; 69.1%) and vaccination programmes (679; 65.9%). The majority of the sample followed socio-epidemiological measures and did not visit places of mass social gatherings (666; 64.1%) and wore masks (992; 95.7%) while being outside their home. In terms of vaccination rates, 382 (37.0%) of the individuals were presently immunized against COVID-19. Higher knowledge test scores (>15 points) (odds ratio = 1.66, p = 0.002) and positive attitudes of this study (odds ratio = 1.59, p = 0.001, odds ratio = 4.16, p < 0.001) were identified as independent predictors for vaccinating against COVID-19. Conclusion: Romanian citizens have had good knowledge, optimistic attitudes and appropriate practices towards COVID-19 vaccination during the third wave of COVID-19 outbreak in the country. Higher knowledge regarding the disease and vaccination against it not only increased attitudes towards the end of the pandemic, but also increased the willingness to be vaccinated and to avoid infection risk factors.

COVID-19-Related Stress, Fear and Online Teaching Satisfaction among Nursing Students during the COVID-19 Pandemic.

The COVID-19 pandemic has had a significant impact on mental health, particularly among students, due to COVID-19-related fear and also the transition from traditional to online lectures. In this questionnaire-based study, the COVID-19 Stress Scales (CSS), the Fear of COVID-19 Scale (FCV-19S), and the Online Teaching Satisfaction Scale were used to assess COVID-19-related fear, stress, and overall satisfaction with online teaching during the COVID-19 pandemic among nursing students in Serbia. A total of 167 students participated in the study, whose mean age was 21.3 ± 5.3, and the majority of whom were female and first-year students. Overall, most students experienced moderate to extremely high COVID-19-related stress levels. Overall, first-year and fourth-year students scored significantly lower regarding the Xenophobia and Traumatic stress subscales than second-year and third-year students, whereas first-year students also scored significantly lower on the Danger and Contamination subscales. First-year students experienced less COVID-19-related fear compared to senior students. Students were reasonably satisfied with online teaching. A stratified program is needed to prevent further decline of students' mental health and to improve their adaptation through public, health, and educational changes.

Echocardiographic Findings of Covid-19 Patients in Canton Sarajevo During the Third Wave of the Covid-19 Pandemic.

Background: Increasing evidence indicates that COVID-19 may result in cardiac issues in certain individuals, such as myocarditis, arrhythmias, and heart failure. Ongoing research on echocardiographic manifestations is still limited. Objective: To investigate the incidence and patterns of left and right ventricular dysfunction in COVID-19 patients. Methods: This study retrospectively observed COVID-19 patients admitted to the Clinical Center of University of Sarajevo during the third wave, with a particular focus on cardiac evaluations. Results: Our patients, predominantely male 155 (72.4%), with a mean age of 66.2±11.4, having hypertension 86 (40.1%), diabetes mellitus 61 (28.5%), hyperlipidemia 144 (67.3%), were active smokers 87 (40.6%), had family history of cardiovascular diseases 123 (57.5%) and were COVID-19 positive 95 (44.4%), presented because of chest pain 78 (36.4%), dyspnea 103 (48.1%), palpitations 67 (31.3%), fatigue 106 (49.5%) and peripheral oedema 30 (14.0%). COVID-19 patients reported much higher symptoms of dyspnea (65 (68.4%) vs 38 (31.9%)) and fatigue (73 (76.8%) vs 33 (27.7%)) than COVID-19 negative patients. On the initial laboratory report, COVID-19 patients had a significantly (p<0.05) higher mean score of C-reactive protein (24.0±4.8 vs. 6.0±2.1), D-dimer (1.6±2.5 vs 0.8±0.6), ALT (94.8±17.2 vs 36.5±19.9) and creatinine (128.0±80.8 vs. 93.4±40.1) when compared to COVID-19 negative patients. COVID-19 patients had enlarged left atrium diametes (31.6±5.6 vs 27.5±5.3), enlarged left ventricular diameter both in systole (27.9±18.1 vs 23.3±16.3) and diastole (39.3±24.1 vs 34.9±22.7), reduced left ventricular ejection fraction (53.5±9.2 vs 59.8±4.3) and elevated right ventricular systolic pressure (37.0±16.4 vs 35.1±8.6). Conclusion: COVID-19 patients had enlarged left atrium, enlarged systolic and diastolic left ventricular diameter, reduced left ventricular ejection fraction and elevated right ventricular systolic pressure.

COVID-19 Vaccination Outcomes and Antibiotic Crisis and Overuse During the COVID-19 Pandemic in Bosnia and Herzegovina.

Background: COVID-19 has different presentations from mild flu like symptoms such as anosmia, dysgeusia, fever, sore throat, cough, dyspnea, headache, abdominal pain and diarrhoea to severe COVID-19 with the development of acute respiratory syndrome (ARDS), septic shock, metabolic acidosis, coagulation dysfunction, multiorgan failure or even death. Objective: The aim of this research project was to present and highlight the outcomes of the vaccination against COVID-19 and the widespread use of antibiotics during the initial admission and treatment of COVID-19 patients in out of hospital settings. Methods: This observational cross-sectional study was conducted between September 1st and September 24th 2021, during the fourth wave of COVID-19 outbreak in Bosnia and Herzegovina, among the patients admitted to the primary health care COVID-19 centre of Canton Sarajevo in Bosnia and Herzegovina. Results: Patients were mostly female 213 (53.3%), with a mean age of 48.8±18.6, with hypertension 129 (32.3%) or diabetes mellitus 35 (8.7%) as comorbidities and being COVID-19 unvaccinated 236 (59.0%) COVID-19 unvaccinated patients expressed more fever (X 2=9.93, p<0.05), had typical COVID-19 chest X ray presentation (X 2=6.08, p<0.05) and abnormal lung auscultation sounds (X 2=5.43, p<0.05). Out of all patients, 312 (78.0%) have received antibiotics and 3 (0.75%) antivirotics such as favipiravir as therapy for the treatment of COVID-19. The mean duration of the antibiotic regime was 10.2 ± 7.5 days with a minimum of 3 days and maximum of 62 days. The minimum CRP value when antibiotics were prescribed was 0.1 (ref. value <5mg/l). The most prescribed antibiotic was doxycycline 172 (43.0%), followed by ceftriaxone 139 (34.7%) and azithromycin 108 (27.0%). Conclusion: Our study showed that vaccination acts protective for the development of severe COVID-19 forms, as well as that antibiotics were overused among COVID-19 infected. The outcome of such malpractice could lead to antimicrobial resistance which will be seen in further years. Governmental agencies should advise physicians to change these trends.

Sexual Patterns, Menstrual Health Status and Prevalence of Modern Contraceptive Use Among Reproductive Aged Females in Bosnia and Herzegovina During the Covid-19 Pandemic.

Background: Nowadays, most women of reproductive age utilize various methods of contraception to avoid undesired pregnancy and regulate menstrual cycles. Objective: The aim of this study is to evaluate current sexual patterns, menstrual health status and use of contraceptive methods in reproductive aged females in Bosnia and Herzegovina during the COVID-19 pandemic. Methods: This cross-sectional study was conducted in the period between February 21st and March 5th 2022 via an online anonymous questionnaire which was distributed using social media platforms. Results: Menstrual periods were normally regular in 269 (85.7 %) of the females, whereas 45 (14.3 %) experienced irregular menstrual cycles. Females report having either one sexual partner 149 (47.5%) or no sexual partners 76 (24.2%) and typically no 92 (29.3%) or frequent (more than 8 sexual intercourses) sexual intercourses per month. The usage of contraceptive methods was reported among the majority 212 (67.5%) and mostly by using of male condom 104 (33.1%), followed by the withdrawal method 64 (20.4%), oral contraceptive pills 35 (11.1%), emergency contraceptive pills "after 24h" 2 (0.6%) and intrauterine device 7 (2.2%). The usage of contraceptive methods was higher among younger females (X2=18.07, p<0.001) and among those who were employed (X2=10.86, p<0.001). Those who used oral contraceptive pills used mostly pills that are combination of progesterone and oestrogen 32 (91.4%) and for the purpose of regulation of menstrual cycles 26 (74.2%) and to prevent unwanted pregnancies 9 (25.8%). Females who had no sexual intercourses per month (OR+0.27, 95% CI 0.09-0.79, p=0.018) were less likely, while those who had irregular menstrual cycles (OR=2.44, 95% CI 1.04-5.71, p=0.039) were more prone to use oral contraceptive pills. Conclusion: Bosnia and Herzegovina reproductive aged female had relatively regular menstrual cycles, the majority used modern contraceptive methods to prevent unwanted pregnancies or for the regulation of menstrual cycles during the COVID-19 pandemic.

Pericardial Effusion in Postcoronavirus Disease Patients with Preserved Ejection Fraction of the Left Ventricle and Normal Values of N-Terminal-Pro B-Type Natriuretic Peptide-Link with C-Reactive Protein and D-Dimer.

Aim: The aim of this study was to link the values of D-dimer and C-reactive protein (CRP), with the occurrence of pericardial effusion in patients who had coronavirus disease 2019 (COVID-19) and have preserved systolic function of the left ventricle (LV). Methods: This was a prospective study and included 146 patients who underwent echocardiographic examination 30 days after the acute phase of COVID-19. Patients who were placed on mechanical ventilation, patients who had pulmonary thromboembolism or acute coronary syndrome during the acute period of the disease, patients who had an ejection fraction of the LV <50%, patients who were diagnosed with pericarditis during acute illness or clinical signs of heart failure (or had elevated N-terminal-pro hormone B-type natriuretic peptide value), with verified renal or hepatic dysfunction were excluded from the study, including patients with diabetes mellitus Type 1, patients with cancer, connective tissue disease, or pregnant women. The existence of cardiovascular risk factors (hypertension, diabetes mellitus Type 2, and hyperlipidemia), the presence of previous ischemic heart disease, maximum values of D-dimer, and CRP (during the first 15 days of the disease) was taken into the analysis. Results: Effusion was verified around the right atrium (RA) in 104 patients (3.85 ± 1.75 mm), in 135 patients next to the free wall of the right ventricle (RV) (5.24 ± 2.29 mm), in front of the apex of the LV in 27 patients (2.44 ± 0.97 mm), next to the lateral wall of LV in 35 patients (4.43 ± 3.21 mm), and behind the posterior wall of LV in 30 patients (2.83 ± 1.62 mm). Mean CRP values during the acute phase of the disease were 43.0 mg/L (8.6-76.2 mg/L), whereas D-dimer mean value was 880.00 µg/L (467.00 -2000.00 µg/L). CRP values correlated with effusion next to the free wall of RV (rho = 0.202; P = 0.018). The D dimer correlated with effusion around RA (rho = 0.308; P = 0.0001). Conclusion: The clinical picture of the post-COVID patients could be explained by the appearance of pericardial effusion. D-dimer value correlates with the occurrence of effusion around RA, whereas CRP value correlates with effusion next to the free wall of RV.

Mental Health and Substance Abuse Among the Bosnia and Herzegovina Student Population During the COVID-19 Outbreak.

Background: Mental health, substance abuse and suicidal ideation present an emerging healthcare problem during COVID-19 pandemic as a result of socio-epidemiological measures, isolations, work modifications, constant media overload with COVID-19 related news and no effective cure for the disease. Objective: The aim of this study was to analyse substance abuse, suicidal ideation and mental health status among university students during the COVID-19 outbreak in Bosnia and Herzegovina. Methods: This cross-sectional study, was conducted via an online anonymous questionnaire based on a Patient Health Questionnaire-4 and Impact of Event Scale-6 which was distributed to the student population of Bosnia and Herzegovina. Results: In total 827 subjects, the majority of whom were female (636), had a high school degree (431), were unemployed (587), lived in an urban environment (747) and had a median age of 23.0 (21.0,32.0), completed the questionnaire. Being female [(OR=1.643, p=0.040); (OR=1.643, p=0.032)], taking sedatives [(OR=1.519, p<0.001); (OR=1.250, p=0.029)] and having high IES-6 score [(OR=2.190, p<0.001); (OR=2.013, p<0.001)] were independent predictors of developing depressive and anxiety symptoms during the COVID-19 outbreak, respectively. Suicidal ideation was present in 71 subjects, with 11 attempting to commit suicide. Sedative (OR=1.381, p=0.005) or alcohol (OR=1.493, p=0.002) use, unemployment (OR=4.551, p<0.001) and depressive symptoms (OR=7.261, p<0.001) were independent predictor of developing suicidal ideation. Conclusion: Bosnia and Herzegovina students show a significant prevalence of anxiety and depressive symptoms, trauma- and stressor-related disorder related to the pandemic, suicidal ideation and substance abuse during the COVID-19 outbreak, especially in association with gender, occupation and abuse of a specific substance.

Recanalization rate of proximal deep venous thrombosis related to therapeutic modality during six months follow-up.

Aim To evaluate the efficacy (rate of recanalization) of therapy with novel oral anticoagulants (NOAC; rivaroxaban, apixaban) compared to conventional treatment (low molecular weight heparin - LMWH and vitamin K antagonist) in the treatment of deep vein thrombosis (DVT) of the proximal segments of lower extremities. Methods The first group consisted of patients diagnosed with DVT and treated with NOAC (n = 100), while the second group consisted of patients diagnosed with DVT, who were treated by conventional treatment (low molecular weight heparin and vitamin K antagonists) (n = 100). In the first group, NOAC was included in the initial treatment. Patients in the second group were treated with LMWH for four days, and on the fifth day vitamin K antagonist was included in therapy, international ratio (INR) was titrated to therapeutic values (2.0-3.0), and then low molecular weight heparin was excluded from the therapy. Results There was a statistically significant difference in the estimated values of free lumen of the blood vessel between the examined groups after 30 days (p=0.0001), after 90 days (p=0.0001) and after 180 days (p=0.0001). After 180 days, the average free lumen values in the NOAC group were 85% (81-89%), which was significantly higher than the free lumen values in the second group, 73% (69-79%). Conclusion The use of NOAC represents more efficient treatment of DVT comparing to vitamin K antagonists.

Bystanders' cardiopulmonary resuscitation involvement in the treatment of out-of-hospital cardiac arrest events and educational status regarding basic life support measures and automated external defibrillator usage among residents in Canton Sarajevo, Bosnia and Herzegovina.

Aim To investigate bystanders' CPR involvement in out-of-hospital cardiac arrest (OHCA) events, their current knowledge regarding OHCA and BLS measures, their willingness to learn BLS measures with the usage of AEDs, as well as current practices. Methods This cross-sectional study included: data regarding all OHCA events treated at the Emergency Medical Service of Canton Sarajevo between January 2015 and December 2019, and an online anonymous questionnaire that examined knowledge, attitudes and practices regarding basic life support (BLS) and automated external defibrillators (AEDs). Results A total of 328 (24.0 %) of 1362 OHCA events achieved the return of spontaneous circulation (ROSC). OHCA incidence was 62/100.000 inhabitants per year. Male gender (p=0.043) and younger age (p<0.001) were significantly associated with obtaining ROSC. Only 44 (3.2%) OHCA events were assisted by bystanders, who were mostly medical professionals 38 (86.4%), followed by close family members 6 (13.6%). There was no report of AED usage. BLS and AED knowledge test score was in the range 12.0-89.8% with generally poor knowledge. Our residents agreed that BLS measurements are essential, 1604 (86.7 %) and that BLS should be a part of their curriculum, 1678 (90.7 %). Conclusion The prevalence of OHCA events in Bosnia and Herzegovina is similar to the region; ROSC among OHCA events was lower than European average, but among highest in the region. There was an extremely low rate of bystander engagement and no AEDs usage. Governmental institutions and health agencies should intervene to increase population knowledge thus increasing OHCA survival rate.
