Introduction: Neovascular glaucoma (NVG) is a severe type characterized by forming new blood vessels on the iris and the anterior chamber angle, often resulting from ischemic retinal diseases. Pars plana vitrectomy (PPV) is a standard surgical procedure for treating various retinal and vitreous conditions. Understanding the risk factors associated with NVG development following PPV is crucial for improving patient outcomes. Objective: To identify and evaluate demographic, clinical, and surgical risk factors associated with developing NVG following PPV. Patients and methods: A prospective cohort study was conducted over two years, involving 60 type 2 diabetes mellitus (T2DM) patients (31 males and 29 females; mean age 60.48±9.63 years) who underwent PPV at the Eye Clinic and Department of Clinical Immunology, University Clinical Center Sarajevo, Sarajevo, Bosnia and Herzegovina. Patients were thoroughly informed about the study, and written informed consent was obtained. Comprehensive data collection included demographic information, medical history, preoperative and postoperative eye examinations, and intraoperative details. Statistical analyses were performed using IBM SPSS Statistics for Windows, Version 21 (Released 2012; IBM Corp., Armonk, New York, United States). Results: Within 12 months postoperatively, 17 patients (28.3%) developed NVG. Significant preoperative risk factors for NVG included prolonged duration of T2DM (p=0.037), elevated preoperative intraocular pressure (IOP) (p=0.024), and higher levels of vascular endothelial growth factor (VEGF) (p=0.011). Intraoperative factors, such as sharp dissection (p=0.000) and operative complications (p=0.004), were also significantly associated with NVG development. Multivariate logistic regression analysis identified prolonged T2DM duration (OR 1.132, p=0.023), increased preoperative IOP (OR 1.192, p=0.029), elevated VEGF levels (OR 1.002, p=0.016), and intraoperative sharp dissection (OR 0.114, p=0.006) as independent risk factors. Conclusions: Multiple preoperative and intraoperative factors influence the development of NVG post-PPV. Prolonged T2DM duration, elevated preoperative IOP, high VEGF levels, and specific intraoperative techniques significantly increase the risk of NVG. These findings underscore the importance of careful preoperative assessment and tailored intraoperative strategies to mitigate NVG risk in PPV patients.

BACKGROUND Thanks to modern methods of assisted reproduction (ART), parenthood has become an attainable goal for couples in which the male partner has experienced spinal cord injury (SCI). OBJECTIVE The aim of our study was to determine the success of the treatment of infertile patients with SCI with intracytoplasmic sperm injection (ICSI) of cryopreserved sperm obtained by the testicular sperm aspiration (TESA) procedure. METHODS In this retrospective study 156 infertile couples were included, in which the male partner is primarily infertile due to azoospermia. Infertile couples were divided into two groups. The first group (n= 82) includes men with SCI, and the second (n= 74) men with obstructive azoospermia (OA) as the cause of infertility. All infertile men were examined and processed in the diagnostic procedure, and based on the urological findings, surgical extraction of sperm from the testicles was indicated. Exclusion criteria were the age of women over 40 and men over 45. RESULTS We found that the quality of sperm was worse in the group with SCI, compared to the group with OA, but without statistical significance. Zenica and Johnsen score (p= 0.001; p= 0.000) showed worse semen characteristics in the group with SCI.     There were no significant differences in the average number of embryos (p= 0.698), pregnancy rates per cycle (p= 0.979) and pregnancy rates per embrio transfer (ET), clinical pregnancy rates per ET (p= 0.987) and delivery rates per ET (p= 0.804) in couples with SCI, compared to couples with OA. CONCLUSION Based on the results of this research, the TESA and ICSI procedures can be recommended as a successful method in the treatment of male infertility caused by azoospermia due to SCI.

In this case report, we describe the diagnostic modality of sinus of Valsalva aneurysm (SOVA) in combination with congenital cardiac defect, aortic valve involvement, and conduction abnormality in a 19-year-old patient. Aim of article was to understand the importance of clinicians being cautious about SOVA presenting in young patients, despite cases being rare, and that SOVA requires a thorough SOVA diagnostic approach. We further provide a review of literature highlighting and comparing the treatment options for both unruptured and ruptured SOVAs. The patient presented for examination due to tachycardia and palpitations. A murmur was heard, and the patient was found to have an atrioventricular nodal reentry tachycardia. Echocardiographic evaluation, magnetic resonance imaging, and computed tomography angiography confirmed an aneurysmally dilated aortic root, aortic regurgitation, and ventricular septal defect. Surgical intervention was indicated; however, the patient refused to undergo surgery.

Background: Peripheral arterial disease (PAD) is highly prevalent and has a well-known association with diabetes. It is still unknown if diabetes worsens clinical outcomes after lower extremity revascularization (LER). Research question: What is the impact of diabetes on clinical outcomes in patients with PAD undergoing LER. Goals: In this meta-analysis, we assessed the effect of diabetes on mortality, major limb amputation, and major adverse cardiovascular events (MACE) in patients with PAD following endovascular or open LER during the perioperative period and within 30 days of follow-up. Methods: We performed a systematic search of PubMed, Embase, and Cochrane databases to December 2023, including studies that compared the clinical outcomes of patients with diabetes and without diabetes following LER procedure. Review Manager 5.4 was used for statistical analysis. I 2 statistics were used to examine heterogeneity. A random-effects model was applied to all analyses. Results: Of the 3,810 articles screened, five observational studies with 55,444 patients were included. A total of 51.13 % had diabetes. There was no significant association between diabetes and mortality (RR 0.96; 95 % confidence interval (CI) 0.74 - 1.26; I 2 = 69%; P = 0.79; Figure 1A). However, diabetes was associated with a significantly increased risk of major limb amputation by 50% (RR 1.50; 95 % CI 1.03 - 2.21; I 2 = 94%; P = 0.04; Figure 1B), and an 18% significantly higher risk of experiencing MACE (RR 1.18; 95 % CI 1.08 - 1.29; I 2 = 0%; P = 0.0005; Figure 1C). Conclusion: Our findings suggest that diabetes is associated with an increased risk of major amputation and MACE but not with mortality in patients following LER.

Two main types of cardiac amyloidosis (CA) exist, as a result of either aberrant plasma cell production of misfolded monoclonal light chains, known as immunoglobulin light chain amyloidosis (AL), or production of disintegrated and misfolded transthyretin (TTR) proteins by the liver, also called transthyretin amyloidosis (ATTR). Non-invasive diagnostics (cardiac uptake on diphosphonate scintigraphy, Perugini score 2 or 3) have gained prominence in modern cardiology in correlation with the negative findings of free light chains in serum and the results of negative immunofixation in serum and urine. Additionally, criteria related to echocardiography or cardiac magnetic resonance are necessary for establishing a diagnosis. A total of 3.063 99mTc-MDP bone scintigrams were analyzed between August 2018 and March 2023, of which Perugini score 1 was validated in 13 patients, Perugini score 2 in 10 patients and Perugini score 3 in 1 patient. From our experience, we could observe that cardiac uptake can be verified in daily clinical practice and that is meaningful for monitoring patients with ATTR-cardiomyopathy (ATTR-CM). Although the sample size is not large, the importance of the study lies in the fact that it involves patients whose findings have been incidentally verified. If patients are selected according to clinical characteristics, the number of positive findings may potentially increase. Our study aimes to raise awareness among physicians of various specialties about the significance of the diagnostic algorithm for infiltrative cardiomyopathies. This is to ensure early diagnosis of this problem and initiation of treatment in the earliest stages when the therapeutic effect is most optimal. Such an approach would yield benefits for both patients and the entire healthcare system. A meticulous diagnostic and therapeutic approach is therefore fundamental for improving clinical outcomes in patients with ATTR-CM, including careful attention to specific TTR genetic variants and long-term follow-up.

Abstract Objectives Prenatal cardiology is a part of preventive cardiology based on fetal echocardiography and fetal interventional cardiology, which facilitates treatment of congenital heart defects (CHD) in pediatric patients and consequently in adults. Timely prenatal detection of CHD plays a pivotal role in facilitating the appropriate referral of pregnant women to facilities equipped to provide thorough perinatal care within the framework of a well-structured healthcare system. The aim of this paper is to highlight the role of left atrial strain (LAS) in prenatal evaluation of fetal heart and prediction of structural and functional disorders. Methods We conducted a comprehensive literature review searching PubMed for articles published from inception up until August 2023, including the search terms “left atrial strain”, “fetal echocardiography”, and “prenatal cardiology” combined through Boolean operators. In addition, references lists of identified articles were further reviewed for inclusion. Results Our review underscores the significance of LAS parameters in fetal echocardiography as a screening tool during specific gestational windows (starting from 11 to 14 weeks of gestation, followed by better visualization between 18 and 22 weeks of gestation). The left atrial strain technique and its parameters serve as valuable indicators, not only for identifying cardiac complications but also for predicting and guiding therapeutic interventions in cases of both cardiac and noncardiac pregnancy complications in fetuses. Evidence suggests establishment of second-trimester reference strain and strain rate values by speckle-tracking echocardiography in the healthy fetal cohort is essential for the evaluation of myocardial pathologies during pregnancy. Conclusions Finding of LAS of fetal heart is feasible and probably can have potential for clinical and prognostic implications.

Objective: Advanced proliferative diabetic retinopathy can lead to serious ophthalmological complications, including blindness. This research aimed to determine visual outcomes after pars plana vitrectomy secondary to proliferative diabetic retinopathy, as well as to identify its predictors. Methods: This prospective clinical study was performed in the Ophthalmology Clinic of the Clinical Centre University of Sarajevo. 60 subjects (eyes) with performed pars plana vitrectomy secondary to proliferative diabetic retinopathy were included in the study. Results: After univariate linear regression analysis, glucose, HbA1c, vascular endothelial growth factor, previous pan-retinal laser photocoagulation, baseline best corrected visual acuity, gas injection, vitreous haemorrhage, iris rubeosis, and glaucoma were found to be statistically significant parameters associated with postoperative visual outcome (p<0.05). Multivariate linear regression analysis was performed to evaluate the association between factors and postoperative best corrected visual acuity. Only intravitreal vascular endothelial growth factor concentration, previous pan-retinal photocoagulation, and gas injection remained statistically significant associated with postoperative best corrected visual acuity (p<0.05). Conclusion: Vitrectomy is an effective treatment for advanced proliferative diabetic retinopathy. Factors correlated with the better visual outcome are good systemic control, previous pan-retinal photocoagulation, low intravitreal vascular endothelial growth factor concentration, younger age, intraoperative internal gas tamponade, combined phacoemulsification and pars plana vitrectomy surgery, and the absence of postoperative complications.

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.
