The best maintenance therapy after a steroid-responsive acute severe ulcerative colitis (ASUC) episode remains poorly studied and is not addressed in current guidelines. We aimed to compare the impact of different treatment strategies following hospitalization for steroid-responsive ASUC. Multicentric, multinational, retrospective cohort study including patients hospitalized with ASUC, between 2010-2021, who responded to intravenous steroids (Oxford Criteria). Patients were categorized according to treatment instituted after discharge - 5ASA, immunomodulators (IMM) and advanced therapy (AT). AT was considered as the reference for comparison. Our primary outcome was a composite of time until disease progression (need for steroids, need for therapy change, new hospitalization or colectomy); secondary outcomes were each event analyzed separately. Survival analysis and multivariate cox regression were performed. 271 steroid-responsive patients from 19 countries were included; median-age at diagnosis was 33 (IQR 25-48) years, 49% were male, 49% had extensive colitis at diagnosis; median disease duration was 26 (IQR 3.0-92.3) months. Following hospitalization for steroid responsive ASUC, 34% of patients received 5-ASA as a maintenance therapy, 23% IMM and 43% AT. During a median follow up of 59 months (IQR 38-92), 68% had disease progression: new course of steroids was needed in 40%, therapy change in 54%, new hospitalization in 33% and colectomy in 10%. In univariate analysis, patients treated with 5-ASA had a trend towards earlier disease progression, compared to AT (HR 1.37, CI 95% 0.99-1.91, p=0.06), earlier need for steroids (HR 1.70, CI 95% 1.11-2.59, p=0.014) and therapy change (HR 1.68, CI 95% 1.15-2.43, p=0.007). In multivariate analysis, adjusting for age and disease extension at diagnosis, disease duration, use of AT prior to ASUC hospitalization, and period of hospitalization (2010-2015 vs 2016-2021), patients treated with 5-ASA had a higher risk of disease progression compared to both IMM (HR 1.50, CI 95% 1.02-2.21, p=0.041) and AT (HR 1.86, CI 95% 1.26-2.74, p=0.002) – Figure 1. No differences were seen between IMM and AT in uni- and multivariate analysis. Shorter disease duration (HR 0.99, CI 95% 0.99-0.99, p=0.007), and prior use of AT (HR 1.67, CI 95% 1.13-2.47, p=0.010) were also associated with higher risk of disease progression – Table 1. After an episode of steroid-responsive ASUC, shorter disease duration and prior use of advanced therapy were risk factors for disease progression. Approximately 1/3 of patients was treated with 5ASA alone. This strategy was also associated with a higher risk of poor outcomes and should be avoided.

AIM To investigate immigrant women's experiences of childbirth in Swedish maternity care. METHODS A systematic search was conducted in PubMed, Embase, CINAHL, and Web of Science for qualitative and quantitative literature on immigrant women's experiences with Swedish maternity care. An inductive thematic analysis generated themes and subthemes. RESULTS Sixteen studies were included in this research. The three main themes were access to healthcare, professional treatment, and feeling significant in care. Key findings revealed that immigrant women struggled with trauma, difficult interactions with midwives, communication issues, interpreter problems, lack of detailed information, the role of doulas, and future concerns. CONCLUSION Immigrant women's experiences of Swedish maternity care were marked by information gaps, ignorance, and disrespect, leading to mistrust and delayed help-seeking. Language barriers with midwives caused misunderstandings. A sense of belonging to Swedish society was crucial for a positive experience. More qualitative research, education in transcultural care, and training in interpreter use are needed to improve maternity care for foreign women.

AIM Lung ultrasound (LUS) can be used for an assessment of volume overload in patients with end-stage kidney disease (ESKD) and those undergoing dialysis. The aim of this study was to analyse whether the initial use of LUS in evaluating volume status could benefit patients by optimizing haemodialysis treatment and improving their clinical status. METHODS The study included 50 haemodialysis patients in stage V of ESKD with the diagnosis of ischaemic heart failure with reduced (HFrEF) or midrange ejection fraction (HFmrEF). The assessment of volume status was verified solely by LUS (along with the analysis of B lines as measures of volume status). The specified laboratory parameters were performed initially, after three, and after six months. RESULTS The number of B-lines on LUS were decreased during the six-month follow-up compared to baseline, indicating a reduction in volume overload due to the LUS-guided protocol. Statistically significant differences were observed in the average creatinine (p=0.001) and parathormone (PTH) (p=0.003) levels over the six-month monitoring period. Significant differences were also noted in triglyceride (p=0.000) and potassium (p=0.02) levels. No significant differences were found in the values of other monitored parameters. CONCLUSION In haemodialysis patients diagnosed with heart failure, LUS can aid the achievement of a more efficient volume reduction by decreasing B-lines, which are indicative of congestion. Our study also demonstrated beneficial effects of LUS on potassium and parathormone levels.

AIM To determine the effects of high peri- and postoperative doses of vitamin C administration on severity of pain in postoperative period and functional outcome of the patients with trochanteric fracture treated with intramedullary nailing during a three-month follow-up. METHODS A prospective, randomized, pilot study included 56 patients who were randomly divided into vitamin C (intervention) and control groups. In the intervention group, patients received vitamin C perioperatively by an intravenous route for 2 days, and oral vitamin C for 38 days postoperatively. Baseline characteristics, postoperative metamizole consumption, Visual Analogue Scale (VAS) score, Harris Hip Score (HHS) value, and the prevalence of complications were evaluated in both groups. RESULTS No significant differences were noted between the groups regarding age, gender, length of hospitalization, and distribution in fracture type. Postoperative metamizole consumption was notably higher in the control group compared to the vitamin C group (p=0.006). Postoperative VAS score was higher in the control group (p< 0.05). No significant differences in HHS values were detected between the groups at 6 and 12 weeks postoperatively (p=0.655 and p=0.755, respectively). The group variable significantly contributed to VAS score, and age and gender variables significantly contributed to HHS value. CONCLUSION A significant reduction of subjective pain levels and lower analgesic consumption was found in patients who received vitamin C, suggesting that it should be considered as an adjuvant agent for analgesia in patients with hip fracture.

AIM Moderate to severe asthma patients with sufficient and insufficient vitamin D serum level, respectively, were assessed with quality of life questionnaires before and after treatment with vitamin D added to their standard asthma treatment. METHODS Patients with moderate to severe asthma have been divided into two groups based on a serum level of vitamin D as sufficient or insufficient level of vitamin D, respectively. During 12 months, a total of 120 patients with sufficient level of vitamin D as well as 120 patients with insufficient level were given treatment with 2000 IU vitamin D for a three-month period. Quality of life of all patients was assessed by Asthma Control Test (ACT), Asthma Quality of Life (AQOL) and the physician's assessment expressed through the Global Evaluation of Treatment Effectiveness (GETE), which were performed before and after the treatment with Vitamin D. RESULTS Values of ACT and AQOL were higher after the treatment with vitamin D in both groups of patients. Values of GETE were lower after the treatment with vitamin D in both groups. All assessed components, psychological, physical, as well as the subjective feeling of control of the disease assessed by treating physicians, showed improvement after treatment. CONCLUSION Adding vitamin D in the treatment regimen of moderate to severe asthma patients improves quality of life and general asthma treatment effectiveness.

Since the design of wireless MIMO systems requires knowledge of the double-directional (i.e., directionally resolved at both link ends) channel characteristics, and 5G/6G use higher frequency bands, there is the need for double-directional measurements in the mmWave spectrum, along with channel sounders that can accurately perform such measurements. This paper introduces a novel channel sounding approach based on a redirecting rotating mirror arrangement (ReRoMA). The method is low-cost and flexible as it requires only a single radio frequency chain at each link end and performs mechanical beamsteering. However, in contrast to existing rotating-horn systems, it physically separates the signal generation/transmission and the beam steering components, resulting in orders-of-magnitude faster measurements. The paper outlines the fundamental concept, describes details of the implementation, and demonstrates its application and accuracy using a 60GHz prototype for measurements in static reference scenarios, as well as dynamic measurements. We illustrate the detected propagation paths using dynamic angular and delay power spectra and correlate these findings with the surrounding environmental structure. Locations of environmental objects are detected within the Fourier resolution determined by bandwidth and horn width, with no noticeable degradation due to the faster measurements.

The genetic, morphological and taxonomic diversity of the genus Sorbus is due to homoploid and polyploid hybridisation, autopolyploidy and apomixis, which also influence the production and diversity of secondary metabolites, especially flavonoids. The aim of this study was to investigate the relationships and variations of flavonoids in terms of hybrid origin and ploidy level between the parental species and their hybrid derivatives. The sampling design included leaf material of the following Sorbus accessions from ten natural localities: parental taxa (di-, tri- and tetraploids of S. aria; diploid S. torminalis and S. aucuparia) and their di-, tri- and tetraploid hybrid derivatives from crosses of S. aria × S. torminalis (subg. Tormaria) as well as the tetraploid S. austriaca and S. bosniaca, which originate from crosses of S. aria × S. aucuparia (subg. Soraria). We analysed the flavonoid profiles from the leaf fractions by LC-MS. A total of 23 flavonoids were identified, including apigenin and luteolin derivatives, which distinguish the hybrid groups from each other. This profiling highlights the distinctiveness of the Tormaria and Soraria accessions and emphasises the potential of the subg. Tormaria for further research on bioactive compounds in biological studies.

Coronary artery fistulas (CAFs) are rare congenital anomalies, presenting in 0.05–0.9% of cases, characterized by an aberrant connection between a coronary artery and a cardiac chamber or great vessel. Clinical manifestations can include heart failure, myocardial ischemia due to coronary steal, arrhythmias, or infective endocarditis. We report a case of a 39-year-old man initially evaluated in 2016 for peripheral edema and suspected right ventricular (RV) abnormality. Earlier assessments indicated a left anterior descending (LAD) coronary artery–RV fistula, but initial catheterization was nondiagnostic. Transthoracic echocardiography (TTE) revealed a dilated left coronary artery (LCA) and an RV apex aneurysm, confirmed by CT and coronary angiography, showing a 14 mm LAD fistula with large aneurysmal sacs (45.6 × 37.3 mm). Cardiac MRI demonstrated a tortuous LAD fistula draining into RV aneurysmal sacs with preserved biventricular function. Surgical intervention was recommended, but the patient declined and was lost to follow-up until 2022, being asymptomatic. Re-evaluation showed progression in aneurysm size (47 × 45 mm and 16 × 18 mm) without ventricular functional change. Follow-up TTE in 2023 indicated stable findings. This case emphasizes the necessity of multimodal imaging (TTE, CT, MRI, angiography) for CAF diagnosis and management planning. Given the variability in CAF presentation and outcomes, individualized management—including surgical, percutaneous, or conservative strategies—is crucial. Persistent follow-up is essential for monitoring potential complications and guiding treatment, even in asymptomatic patients refusing intervention.

Background and Objectives: Left ventricular aneurysm (LVA) causes geometric changes, including reduced systolic function and a more spherical shape, which is quantified by the sphericity index (SI), the ratio of the short to long axis in the apical four-chamber view. This study aimed to assess SI’s value in A-LVA and B-LVA, identify influencing factors, and evaluate its clinical relevance. Materials and Methods: This clinical study included 54 patients with post-infarction LVA and used echocardiography to determine LVA locations (A-LVA near the apex and B-LVA in the basal segments), with SI and other echocardiographic measures assessed in both systole and diastole for the entire cohort and stratified by A-LVA and B-LVA groups. Results: Among the 54 patients, 41 had A-LVA and 13 had B-LVA. The mean SI was 0.55 in diastole and 0.47 in systole for the cohort. Patients with A-LVA had a mean SI of 0.51 in diastole and 0.44 in systole, while B-LVA patients exhibited significantly higher SI values, with 0.65 in diastole and 0.57 in systole, due to lower long-axis (L) values in both phases. The mean left ventricular ejection fraction (EF) was 23.95% in A-LVA and 30.85% in B-LVA, with no significant difference. However, apical aneurysms were larger (greater LVAV and LVAA) and more significantly reduced functional myocardium. LVEDV, LVESV, LVEDA, and LVESA did not differ significantly between A-LVA and B-LVA. In cases of severe mitral regurgitation (MR), SI was notably higher (0.75 in diastole) due to a marked reduction in the L axis. Conclusions: SI is key in differentiating A-LVA and B-LVA on echocardiography. B-LVA has lower volume and area values, but similar aneurysm and left ventricular volumes and EF. Higher SI in B-LVA is due to a reduced L-axis, and is worsened by severe mitral regurgitation (MR). Surgical ventricular reconstruction (SVR) compensates for L-axis reduction, with preservation of the L axis critical for achieving a more physiological shape. SI thus serves as a marker for left ventricular geometry and surgical outcomes.

Background In addition to age, body mass index (BMI), abdominal circumference, and parity, measuring the mother's pelvic diameters is a non-invasive, cost-effective method that can assist gynecologists in determining the optimal management of labor. Our study aimed to examine the associations between maternal age, pelvic diameters, BMI, abdominal circumference, and parity with delivery outcomes and investigate differences in pelvic diameters in relation to maternal age, BMI, delivery outcomes, parity, and episiotomy. Materials and methods The observational, cross-sectional study included 108 pregnant women in the active phase of labor who were admitted to the Gynecological Clinic at the Clinical Center University of Sarajevo. During admission, maternal data were registered: age, body height, body weight, abdominal circumference, and BMI. Using a pelvinometer, pelvic diameters were recorded: interspinous diameter (DS), intertrochanteric diameter (DT), intercristal diameter (DC), and external conjugate (CE). The Anterior Pelvic Index (API) was calculated by dividing the DS by the participants' height and multiplying the result by 100. Data were analyzed using SPSS Statistics for Windows, Version 17 (Released 2008; SPSS Inc., Chicago, United States). Results Women who underwent cesarean section were significantly older compared to those with spontaneous vaginal delivery. A significant correlation was observed between maternal age, BMI, and delivery outcomes. Obese women had significantly higher DT compared to women with normal or overweight BMI. Primiparous and multiparous women differed significantly in CE, while other pelvic diameters did not differ. Women with episiotomy had significantly lower DS and CE diameters compared to those without episiotomy during vaginal delivery. Conclusion Maternal age, BMI, and pelvic diameters are significant delivery outcome determinants; our findings suggest that these parameters deserve to be included in delivery outcome assessment as they provide substantial information in the journey of achieving personalized delivery care and decision-making.

Simple Summary This research considers means of improving the early detection and treatment of colorectal cancer (CRC), a common and deadly form of cancer often identified too late for effective treatment. In our study, we examined AIFM3, VGLL4, and WNT4 in cancerous and healthy tissues at various stages of CRC. We found that these markers behave differently as the cancer advances. AIFM3 appears in healthy tissue and early cancer stages but disappears as the cancer worsens. VGLL4 increases in the affected tissues as the cancer progresses, particularly noticeable from early to more advanced stages. WNT4 is higher in cancerous tissues, but decreases in the supportive tissue surrounding cancer cells as the disease advances. Low VGLL4 levels are linked to better patient survival, unlike the other two markers. This finding suggests that VGLL4 could be useful as an indicator of CRC prognosis, potentially guiding treatment approaches.

Psoriasis is a chronic inflammatory skin disease with relapsing nature. Estimates are that approximately 2–3% of the world’s population suffers from this disease. More severe forms of psoriasis are conditions of high inflammation, which is confirmed by the clinical picture and numerous inflammatory parameters such as C-reactive protein (CRP), cytokines and homocysteine, which vary with disease activity. The objective of this clinical study was to investigate the effect of GLP-1 receptor agonist semaglutide therapy on pro-inflammatory factors in the serum and the severity of the clinical picture of psoriasis in obese patients with type 2 diabetes mellitus (T2DM) on chronic metformin therapy. This randomized clinical study was conducted on 31 psoriatic patients with T2DM that were randomized into two groups: one that received semaglutide during the 12-week trial (n = 15), while the second was control (n = 16). The results demonstrated that the severity of the clinical picture of psoriasis, determined by the Psoriasis Area and Severity Index (PASI) score, was significantly better after the administration of semaglutide (the median baseline PASI score in patients treated with semaglutide was 21 (IQR = 19.8), while after 12 weeks of therapy the score was 10 (IQR = 6; p = 0.002). Also, the quality of life in the group of patients who received the drug, measured by the Dermatology Life Quality Index (DLQI), improved significantly after 3 months (a median baseline DLQI score in the semaglutide group was 14 (IQR = 5) at the beginning of the study, and after 12 weeks of treatment the median DLQI score was 4 (IQR = 4; p = 0.002)). The use of semaglutide led to a significant decrease in pro-inflammatory cytokines in the serum (IL6), as well as a significant decrease in CRP values (p < 0.05). A significant decrease in the body mass index (BMI) value in the semaglutide-treated group was also identified, as well as a significant decrease in the level of low-density cholesterol (LDL) (p < 0.05). In conclusion, semaglutide, based on its systemic anti-inflammatory characteristics, could contribute to the treatment of psoriatic obese patients with T2DM.
