Povzetek: Background and aims: Cascade familial hypercholesterolemia (FH) screening of parents could reduce the burden cardiovascular disease (CVD) in relatives of index cases by enabling timely diagnosis of FH. Here, we present the positive outcomes of the pilot child-parent cascade screening program in Slovenia. Methods: One hundred and thirty-eight parents from 123 families of an index child with genetically confirmed FH were randomly included in the pilot child-parent cascade screening program. Index children were identified through the universal FH screening program in preschool children. Genetic testing using Sanger sequencing was performed for cascade screening to detect (likely) pathogenic variants, previously confirmed in the index child. Results: The success rate of confirming a (likely) pathogenic variant was 77.2 % when the first parent, preferably with higher total cholesterol levels, was tested, and reached 99.1 % when the variant was identified in the first tested parent or when both parents were tested. In the minority of cases (13.8 %), parents had had a clinical diagnosis of FH prior to their child and these had somewhat higher prevalence of CVD compared to parents that were diagnosed after their index child through the pilot program (12.5 % vs. 4.3 %; p = 0.382). Conclusions: In conclusion, the presented pilot child–parent cascade screening program is feasible in clinical practice and shows a high success rate in identifying parents with FH. Parents diagnosed through the program appeared to have a lower prevalence of CVD. However, larger cohorts are needed to confirm these findings.

Effect of universal antibiotic prophylaxis on prevalence of surgical site infection after cesarean section
Anja Čopi Jerman, Janja Zver, Miha Lučovnik, Samo Jeverica, 2025, izvirni znanstveni članek

Povzetek: Background/Objectives: Cesarean section (CS) is among the most common surgical procedures worldwide and is associated with a markedly increased risk of postpartum infection, including surgical site infection (SSI). International guidelines recommend routine prophylaxis for all CSs, but in Slovenia, it has traditionally been reserved for high-risk procedures, with limited SSI surveillance data. The aim of this study was to determine the incidence of SSI within 30 days after CS and to evaluate the impact of universal prophylaxis implemented in a regional secondary care teaching hospital. Methods: We conducted a retrospective observational cohort study including all CS performed during 2023 (risk-based-only prophylaxis) and 2024 (universal prophylaxis) at Izola General Hospital, Slovenia. SSI was defined according to ECDC criteria and identified from inpatient and outpatient records up to 30 days postoperatively. Logistic regression was used to assess associations between prophylaxis, clinical variables, and SSI. Results: Among 1055 deliveries (208 CS; 99 in 2023, 109 in 2024), the rate of antimicrobial prophylaxis increased from 58.6% to 89.0% (p < 0.001). The overall 30-day SSI incidence was 7.2%, with no significant difference between the pre- and post-implementation periods (8.1% vs. 6.4%, p = 0.644). Most infections (86.7%) were diagnosed after discharge and were superficial incisional SSI (60%). In multivariable analysis, prophylaxis was independently protective (adjusted OR 0.11; 95% CI 0.02–0.58; p = 0.009), while prelabor rupture of membranes (PROM) and higher maternal weight significantly increased SSI risk. Conclusions: Antibiotic prophylaxis was independently associated with a reduced risk of SSI following SC; however, the absolute infection rate did not decline significantly and remained moderate after implementation. PROM and higher maternal weight were additional independent risk factors. These findings support universal prophylaxis with optimization for high-risk women and ongoing hospital and national surveillance to improve CS safety.

Gene therapy of rare diseases as a milestone in medicine : overview of the field and report on initial experiences in Slovenia
Urh Grošelj, Marko Kavčič, Ana Drole Torkar, Jan Kafol, Duško Lainšček, Roman Jerala, Matjaž Sever, Samo Zver, Gregor Serša, Maja Čemažar, Primož Strojan, Aleš Grošelj, Mojca Žerjav-Tanšek, Špela Miroševič, Simona Ivančan, Tomaž Prelog, David Gosar, Jasna Oražem, Matej Mlinarič, Sara Bertok, Jernej Kovač, Jana Kodrič, Saba Battelino, Marko Pokorn, Alojz Ihan, Janez Jazbec, Tadej Battelino, Damjan Osredkar, 2025, pregledni znanstveni članek

Povzetek: Gene therapy has transitioned from a long-awaited promise to a clinical reality, offering transformative treatments for rare congenital diseases and certain cancers, which have a significant impact on patients’ lives. Current approaches focus on gene replacement therapy, either in vivo or ex vivo, mostly utilizing viral vectors to deliver therapeutic genes into target cells. However, refining these techniques is essential to overcome challenges and complications associated with gene therapy to ensure long-term safety and efficacy. Slovenia has witnessed significant advancements in this field since 2018, marked by successful gene therapy trials and treatments for various rare diseases. Significant strides have been made in the field of gene therapy in Slovenia, treating patients with spinal muscular atrophy and rare metabolic disorders, including the pioneering work on CTNNB1 syndrome. Additionally, immune gene therapy, exemplified by IL-12 adjuvant therapy for cancer, has been a focus of research in Slovenia. Through patient-centred initiatives and international collaborations, researchers in Slovenia are advancing preclinical research and clinical trials, paving the way for accessible gene therapies. Establishing clinical infrastructure and genomic diagnostics for rare diseases is crucial for gene therapy implementation. Efforts in this regard in Slovenia, including the establishment of a Centre for Rare Diseases, Centre for the Technologies of Gene and Cell Therapy, and rapid genomic diagnostics, demonstrate a commitment to comprehensive patient care. Despite the promises of gene therapy, challenges remain, including cost, distribution, efficacy, and long-term safety. Collaborative efforts are essential to address these challenges and ensure equitable access to innovative therapies for patients with rare diseases.

The Prevalence of bacterial vaginosis in pregnant women in Slovenia, determined via microscopy and semi-quantitative relative culture, and its association with adverse pregnancy outcomes
Maja Starc, Miha Lučovnik, Petra Eržen Vrlič, Samo Jeverica, 2025, izvirni znanstveni članek

Povzetek: Bacterial vaginosis (BV) is associated with various adverse pregnancy outcomes. It is usually diagnosed via microscopy. Semi-quantitative relative culture (SRC) was investigated as a complementary diagnostic method to determine the prevalence of BV and its association with preterm birth and preterm, premature rupture of membranes (PPROM) in pregnant women in Slovenia. We examined 3437 consecutive vaginal swabs from pregnant women during the five-year period and were able to link the results to 2531 pregnancy outcomes. The isolates were identified using MALDI-TOF, and the results were assessed by the relative amounts of Gardnerella vaginalis and lactobacilli according to two stringency criteria. The prevalence of BV was 6.5% via microscopy and was higher for SRC, 9.9% or 11.1%, depending on the stringency criteria. The association with adverse pregnancy outcomes was better when SRC was used, resulting in adjusted odds ratios of 1.76 (1.30 to 2.37) and 1.97 (1.38 to 2.82) for preterm birth and PPROM, respectively, with more stringent interpretation. Microscopically detected BV was not associated with either outcome. The clinical validity of SRC was demonstrated by its better correlation with adverse pregnancy outcomes in a large cohort of pregnant women. SRC with MALDI-TOF identification is a promising advancement of vaginal culture.

Iodisation of salt in Slovenia : increased availability of non-iodised salt in the food supply
Katja Žmitek, Igor Pravst, 2016, izvirni znanstveni članek

Povzetek: Salt iodisation is considered a key public health measure for assuring adequate iodine intake in iodine-deficient countries. In Slovenia, the iodisation of all salt was made mandatory in 1953. A considerable regulatory change came in 2003 with the mandatory iodisation of rock and evaporated salt only. In addition, joining the European Union's free single market in 2004 enabled the import of non-iodised salt. The objective of this study was to investigate the extent of salt iodising in the food supply. We examined both the availability and sale of (non-)iodised salt. Average sales-weighted iodine levels in salt were calculated using the results of a national monitoring of salt quality. Data on the availability and sales of salts were collected in major food retailers in 2014. Iodised salt represented 59.2% of the salt samples, and 95.9% of salt sales, with an average (sales-weighted) level of 24.2 mg KI/kg of salt. The average sales-weighted KI level in non-iodised salts was 3.5 mg KI/kg. We may conclude that the sales-weighted average iodine levels in iodised salt are in line with the regulatory requirements. However, the regulatory changes and the EU single market have considerably affected the availability of non-iodised salt. While sales of non-iodised salt are still low, non-iodised salt represented 33.7% of the salts in our sample. This indicates the existence of a niche market which could pose a risk of inadequate iodine intake in those who deliberately decide to consume non-iodised salt only. Policymakers need to provide efficient salt iodisation intervention to assure sufficient iodine supply in the future. The reported sales-weighting approach enables cost-efficient monitoring of the iodisation of salt in the food supply.
