Dietary Intake of Folate and Assessment of the Folate Deficiency Prevalence in Slovenia Using Serum Biomarkers.

Folate deficiency is associated with various health issues, including anemia, cardiovascular disease, and birth defects. Low folate intake and suboptimal folate status were found in several countries; however, this topic has not yet been investigated in Slovenia. Dietary folate intake and serum folate status were investigated through the nationally representative food consumption study SI.Menu/Nutrihealth. Folate intake was estimated using a sample of N = 1248 subjects aged 10-74 years, stratified in three age groups (adolescents, adults, elderly population), through two 24 h-dietary recalls and food propensity questionnaire. Data on serum folate and homocysteine was available for 280 participants. Very low folate intake (<300 µg/day) was observed in 59% of adolescents, 58% of adults and 68% of elderlies, and only about 12% achieved the WHO recommended level of 400 µg/day. Major dietary contributors were vegetables and fruit, and cereal products. Living environment, education, employment status and BMI were linked with low folate intake in adults; BMI, and sex in adolescents; and sex in elderlies. Considering low serum folate (<7 nmol/L) and high serum homocysteine (>15 nmol/L), folate deficiency was found in 7.6 and 10.5% in adults and elderlies, respectively. Additional public health strategies should be employed to promote the consumption of folate-rich foods. With current folate intakes, supplementation with folic acid is relevant especially in specific vulnerable populations, particularly in women planning and during pregnancy.

Identification of women at risk for hereditary breast and ovarian cancer in a sample of 1000 Slovenian women: a comparison of guidelines.

BACKGROUND: An important number of breast and ovarian cancer cases is due to a strong genetic predisposition. The main tool for identifying individuals at risk is recognizing a suggestive family history of cancer. We present a prospective study on applying three selected clinical guidelines to a cohort of 1000 Slovenian women to determine the prevalence of at-risk women according to each of the guidelines and analyze the differences amongst the guidelines. METHODS: Personal and family history of cancer was collected for 1000 Slovenian women. Guidelines by three organizations: National Comprehensive Cancer Network (NCCN), American College of Medical Genetics in cooperation with National Society of Genetic Counselors (ACMG/NSGC), and Society of Gynecologic Oncology (SGO) were applied to the cohort. The number of women identified, the characteristics of the high-risk population, and the agreement between the guidelines were explored. RESULTS: NCCN guidelines identify 13.2% of women, ACMG/NSGC guidelines identify 7.1% of women, and SGO guidelines identify 7.0% of women from the Slovenian population, while 6.2% of women are identified by all three guidelines as having high-risk for hereditary breast and ovarian cancer. CONCLUSIONS: We identified 13.7% of women from the Slovenian population as being at an increased risk for breast and ovarian cancer based on their personal and family history of cancer using all of the guidelines. There are important differences between the guidelines. NCCN guidelines are the most inclusive, identifying nearly twice the amount of women as high-risk for hereditary breast and ovarian cancer as compared to the AGMG/NSCG and SGO guidelines in the Slovenian population.

A randomized controlled trial to improve psychological detachment from work and well-being among employees: a study protocol comparing online CBT-based and mindfulness interventions.

BACKGROUND: The changing landscape of the work environment, which often encompasses expectations of employees being continuously available, makes it difficult to disengage from work and recover. This can have a negative impact on employees' well-being, resulting in burnout, depression and anxiety, among other difficulties. The current study will test the effectiveness of two different online interventions (i.e., cognitive behavioral therapy; CBT and mindfulness-based stress reduction; MBSR) on employees' psychological detachment, burnout and other variables related to general (e.g., life satisfaction) and work-specific (e.g., work engagement) well-being. METHODS/DESIGN: The study is designed as a randomized control trial with two intervention groups (i.e., CBT, MBSR) and a waitlist control group. Participants will be full-time employees from a wide range of organizations from Slovenia, who report moderate difficulties with psychological detachment from work and burnout and are not receiving any other form of treatment. The online interventions will encompass 12 sessions over 6 weeks (2 sessions per week); each session will include 1) an active audio-guided session and 2) home assignments, accompanied by handouts and worksheets. The study outcomes (i.e., psychological detachment, burnout, general and work-specific well-being), potential mechanisms (i.e., work-related maladaptive thinking patterns, mindfulness) and moderators (e.g., supervisor support for recovery) will be assessed immediately before and after the interventions (pre and post measurement) and 3 months after intervention completion (follow-up). Additionally, participants will fill out questionnaires for the assessment of the central mechanisms and study outcomes each week. DISCUSSION: We expect that the CBT-based intervention will lead to greater improvements in psychological detachment from work and burnout compared to the MBSR and the waitlist control group. Additionally, we expect that the CBT-based intervention will also lead to greater enhancement of both general and work-related well-being.

Endocrine disorders after heart transplantation: national cohort study.

BACKGROUND: Endocrine disorders in patients after heart transplantation (HT) remain understudied. We aimed to assess endocrine profiles and management of HT recipients in the early post- transplant period. METHODS: We conducted a retrospective cohort study on 123 consecutive HT recipients in the Advanced Heart Failure and Transplantation Programme between 2009 and 2018. All recipients had per-protocol endocrine follow-up within the first postoperative year. The median time to first post-transplant endocrine follow-up was 3 months (IQR 2-4). We assessed the incidence of vitamin D deficiency, bone mineral density, history of low energy fractures, hypogonadism in male recipients, posttransplant diabetes mellitus, and thyroid and parathyroid function. RESULTS: We enrolled 22 women and 101 men of median age 57 years (IQR 50-63). Post-transplant diabetes mellitus developed in 14 patients (11.4%). 18 of 25 patients (14.6%) with preexisting type 2 diabetes mellitus required intensification of antidiabetic therapy. 38 male patients (40.4%) had hypogonadism. 5 patients (4.6%) were hypothyroid and 10 (9.3%) latent hyperthyroid. Secondary hyperparathyroidism was present in 19 (17.3%), 25-hydroxyvitamin D deficiency in 64 (54.7%) of patients. Osteoporosis was present in 26 (21.1%), osteopenia in 59 (48.0%) patients. 47 vertebral fractures, 3 hip and 1 humerus fractures occurred in 21 patients. Most of the patients had coincidence of two or three disorders, while less than 5% did not have any endocrine irregularities. All patients received calcium and vitamin D supplements. Forty-six patients (37.4%) were treated with zoledronic acid, 12 (9.8%) with oral bisphosphonates. Two patients were treated with teriparatide. CONCLUSIONS: The prevalence of multiple endocrine disorders early after heart transplantation is high. Assessment and management of increased fracture risk and all other potentially affected endocrine axes should be considered as a standard of care in this early period.

High Clostridium difficile contamination rates of domestic and imported potatoes compared to some other vegetables in Slovenia.

Clostridium difficile, recently reclassified to Clostridioides difficile, is among most important causes of intestinal infections in humans. Zoonotic potential and foodborne transmissions are considered to be partially involved in C. difficile spread. Here we report prevalence of C. difficile in 142 retail and 12 homegrown vegetables in Slovenia between years 2014 and 2017. The overall prevalence of C. difficile on vegetables was 18,2% (28/154). A total of 115 isolates were obtained which belonged to 25 PCR ribotypes. Ten of those were toxigenic and PCR ribotype 014/020 was the most prevalent. Most of 25 determined PCR ribotypes were previously reported in humans, animals, soil or water in Slovenia. Among tested vegetables, potatoes had the highest positivity rate (28,0% vs. 6,7% and 9,4% for ginger and leaf vegetables). Altogether 66,7% of C. difficile positive potato samples were imported from 12 different countries of three different continents. The origin of contamination could be any point between production and retail store, however, our results suggest a possibility that potatoes represent a transnational and transcontinental way of C. difficile transmissions.

Impact of cephalosporin restriction on incidence of infections with extended-spectrum beta-lactamase-producing Klebsiella pneumoniae in an endemic setting.

Decreasing cephalosporin use was described as an effective intervention in decreasing the incidence of infections caused by Klebsiella pneumoniae harbouring extended-spectrum beta-lactamase (ESBLKP). Due to sustained increased levels of infections caused by ESBLKP, a multifaceted antibiotic stewardship intervention aimed to decrease cephalosporin use was carried out at a large medical unit of a teaching hospital. All cephalosporins except the first-generation were restricted and could only be prescribed after authorization by an infectious disease physician. The use of cephalosporins decreased significantly after intervention. The effect was most prominent for the third-generation cephalosporins (7.9-1.5 DDD/100 OBD). There was an increase in the consumption of piperacillin/tazobactam, carbapenems and fluoroquinolones. In contrast to our expectations the ESBLKP incidence increased, but the changes were not statistically significant. The intervention was successful in controlling the prescribing of cephalosporins, but had no impact on incidence of ESBLKP infections.

Genetic diversity and macrolide resistance of Mycoplasma pneumoniae isolates from two consecutive epidemics in Slovenia.

Two nationwide Mycoplasma pneumoniae epidemics occurred in Slovenia between 2006 and 2016. The aim of this study was to assess which M. pneumoniae genotypes were present in our area during the selected timeframe, whether the origin of the epidemics was monoclonal or polyclonal and whether the proportion between detected genotypes changed over time. We were also interested in the presence of macrolide resistance (MR) and whether it could be linked to specific genotypes. We performed pyrosequencing of the P1 gene and multiple-locus variable-number tandem repeat (VNTR) analysis (MLVA) typing from 872 M. pneumoniae isolates obtained from respiratory tract infections (RTI)-suffering patients. Additionally, isolates were tested for the presence of MR implicated mutations in the 23S rRNA gene. The MLVA typing results revealed that three main genotypes, MLVA-3,5,6,2, MLVA-3,6,6,2 and MLVA-4,5,7,2, were constantly present and occasionally joined by less abundant, short-lived genotypes, which were detected mostly, but not exclusively, during epidemics. We also noticed a switch in abundance from MLVA-3,5,6,2 and MLVA-3,6,6,2, which dominated in the first epidemic (77.0%; 97/126), to MLVA-4,5,7,2 (71.6%; 428/598), which dominated in the second. Similar to this finding, the dominant P1 type also shifted from type 2 to type 1, although a complete P1 type shift was not observed, since both types remained in circulation. MR was detected in 0.8% (7/872) of M. pneumoniae isolates. Our results seem to suggest that MR remains sporadic in Slovenia at this point in time and that both recent epidemics were polyclonal in nature and, possibly, to some extent, fuelled by the P1 type dominance change.

Psychosocial Risk Factors for Low Back Pain and Absenteeism among Slovenian Professional Drivers.

OBJECTIVE: The aim of this study was to determine the most common psychosocial risk factors for absenteeism and the extent to which low back pain occurs among Slovenian professional drivers as result of various psychosocial risk factors. METHOD: The study involved 275 professional drivers, mostly men (mean age 41.6 years). Statistical data analysis was conducted using SPSS package version 21, MS Excel version 2007 and Pajek, version 3. The main method for data processing was regression analysis. RESULTS: The results of the quantitative survey showed that lower back pain is mostly caused by lifting and carrying heavy loads, inadequate working conditions, poor physical fitness, regular nights out, shift work, and stress. Dissatisfaction with work, shift work and unsuitable working conditions significantly affect the incidence of low back pain. Absenteeism is influenced by factors such as dissatisfaction at work, disrespectful attitude of managers, unsuitable working conditions, personal dissatisfaction, lack of understanding of the partner, and enjoying nightlife on a regular basis. CONCLUSIONS: The study clarifies the unexplained holistic psychosocial risk factors and treatment effects on health in the population of professional drivers. Such factors can lead to absenteeism. The study also provides initial demonstration research in the Slovenian practice. Furthermore, it provides solutions in a holistic approach to solve the problem of risk factors management.

Determinants of maternal vitamin D concentrations in Slovenia : A prospective observational study.

OBJECTIVE: To analyze the vitamin D status of pregnant women in Slovenia and the factors influencing it. METHODS: The study was performed in Maribor University Medical Centre (location 46°N). Maternal serum 25-hydroxy-vitamin D (25(OH)D) in 4 groups of 100 pregnant women in 4 different seasons of the year was measured at the time of delivery. Data on life style, eating habits, sunbathing and intake of vitamin D supplements during pregnancy were obtained using a questionnaire. Information on maternal outcome was acquired from medical records. Duration of sunlight and average temperature in the month preceding delivery were calculated from meteorological data. RESULTS: The average maternal 25(OH)D concentration ranged from 28.5 ± 17.1 nmol/l in March to 54.8 ± 24.1 nmol/l in June (p < 0.001). Severe vitamin D deficiency, i.e. <25 nmol/l 25(OH)D was present in 23.6% of women overall. In multiple regression analysis supplements containing vitamin D (ß = 0.225, p < 0.001) and duration of intentional exposure to sunlight (ß = 0.192, p = 0.026) were associated with maternal 25(OH)D status. Significantly lower vitamin D levels were observed in women who had a cesarean section (t = 2.053, p = 0.041) and those with premature delivery (t = 2.296, p = 0.022). Vitamin D levels were not associated with the occurrence of gestational diabetes, gestational hypertension or infections during pregnancy. CONCLUSION: A high prevalence of vitamin D deficiency was detected at the end of pregnancy, especially in the months following autumn and winter and in women who did not take supplements containing vitamin D.

Prenatal mercury exposure, neurodevelopment and apolipoprotein E genetic polymorphism.

The aim of the present study was to evaluate the association between prenatal exposure to mercury (Hg) and neurodevelopment of the child, taking into account genetic polymorphism of apolipoprotein E (Apoe) and other relevant confounders. Six hundred and one mother-child pairs were recruited from the central Slovenia region and 243 from Rijeka, on the Croatian coast of the northern Adriatic. The total Hg in cord blood, Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) assessment at 18 months of age and Apoe genotyping was performed on 361 children; 237 of them were from Slovenia and 124 from Croatia. The results showed negative association between low-to-moderate Hg exposure in children with normal neurodevelopmental outcome and cognitive and fine motor scores at 18 months of age as assessed by Bayley III. The Hg-related decrease in cognitive score was observed only in children carrying at least one Apoe ε4 allele, while the decrease in fine motor scores was independent of the Apoe genotype. Adjusting for selenium (Se) and lead (Pb) levels, a positive association between Se and the language score and a negative association between Pb and the motor score was observed, but not in the subgroup of children carrying the ε4 allele.

Iodisation of Salt in Slovenia: Increased Availability of Non-Iodised Salt in the Food Supply.

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.

Substance use and misuse among Slovenian table tennis players.

Substance use and misuse (SU&M) is regularly studied in sports, but we have found no such data for table tennis. We have studied SU&M in athletes competing at the Slovenian Nationals 2008-2009 (responding rate was 100%; 50 males and 29 females; aged 18 years or older). The anonymous questionnaire for studying SU&M and corresponding educational, socio-demographic, and sport factors was used. More than 90% of all the athletes included in our study do not rely on coaches' and/or physicians' opinion regarding nutritional supplements and doping. Chi-square test revealed higher prevalence of binge drinking, cigarette smoking, and potential doping behavior in males. In both genders, with the advancement of the sport status, the probability for potential doping behavior increases. In conclusion, we strongly suggest permanent SU&M educational programs for table tennis athletes as well as for their coaches and physicians.

Results of adjuvant radiochemotherapy for gastric adenocarcinoma in Slovenia.

AIMS: To analyze the results of postoperative concomitant radiochemotherapy with 5-florouracil (5-FU) and leucovorin (LV) in patients with gastric carcinoma treated in a single institution. METHODS: During 2001-2004, 123 patients with the mean age of 60 years, were treated for adenocarcinoma of the stomach, stage Ib-IV, with postoperative concomitant radiochemotherapy. Radical (R0) and non-radical (R1) resection of the tumor was performed in 107 and 16 patients, respectively. Adjuvant treatment consisted of five cycles of five-day chemotherapy with 5-FU (425 mg/m(2)) and LV (20 mg/m(2)) and concomitant radiotherapy with the total dose of 45 Gy. RESULTS: The treatment was completed according to the protocol in 101 patients. Stomatitis, dysphagia, and nausea and vomiting of grade three occurred in 32, 27, and 23 patients, respectively. The median follow-up time of 87 survivors was 30.4 months (range 17.4-58.3 months). At two years, locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS) and overall survival (OS) rates were 86%, 65%, 74%, and 73%, respectively. In the multivariate analysis, the initial Hb level was identified as independent prognostic factor for all survival four endpoints, the involvement of whole stomach with cancer for LRC, the total dose of 5-FU per five-day cycle for DFS, and pT stage for DSS. CONCLUSIONS: In operable gastric carcinoma, postoperative concomitant radiochemotherapy with 5-FU and LV is feasible and its toxicity acceptable. Its potential to improve the treatment outcome compared to the surgery alone is yet to be tested in well designed prospective randomized studies.

Coffee and alcohol consumption as triggering factors for sudden cardiac death: case-crossover study.

AIM: To estimate the relative risk of triggering sudden cardiac death after coffee or alcohol consumption in out-of-hospital sudden cardiac death victims. METHODS: A case-crossover design with usual frequency approach was used and the study population included persons who died out of hospital due to sudden cardiac death. By mailing 2 questionnaires, 1 to the family members of the deceased and the other to the attending physician, necessary data on the mode of cardiac death, life style, health, and several socio-demographic variables were obtained. Cases were those who died of sudden cardiac death within 1 hour after coffee consumption or within 2 hours after ingesting alcohol; but controls were those who died in the hours when they were not exposed to these stimulans. The relative risk of dying within exposed hours in comparison to non-exposed hours was parameter estimated for each risk factor. RESULTS: Among 309 sudden cardiac death victims who died in the period from January 2000 to March 2001 in Slovenia, there were 253 men and 56 women with median age at death of 57.1 and 57.7, respectively. On average, each of them had 2.8 risk factors for ischemic heart disease, and the estimated relative risk of dying during 1 hour after coffee consumption was 1.73 (95% confidence interval [CI]=1.13-2.65), and within 2 hours after alcohol consumption 3.00 (95%CI=1.61-5.68). Within both coffee drinking and alcohol consuming groups, the relative risk was different among persons with different life style habits. It ranged from 1.50 for the coffee drinkers who had been receiving medication due to risk factors of heart diseases, to 2.63 for former alcohol drinkers. Among alcohol consumers it varied from 2.66 among those who were performing less than 104 hours of physical activity of six metabolic equivalents at least, to 52.15 among those of 90 heart beats or more per minute. CONCLUSION: Our research confirmed the hypothesis that coffee or alcohol consumption is a potential trigger for sudden cardiac death in persons with risk factors for ischemic heart disease.

Primary health care reform in Slovenia: first results.

The paper explains the main features of the primary health care system and its reform in Slovenia. The reform that has started in 1992, was characterized by the following main changes: introducing the national health insurance scheme as opposed to budget financing, a new contrast between providers and the national health insurance and a possibility of independent contracting with the national health insurance. The data show that the number of consultations per person per year has increased, especially in general practice. A possible explanation to that would be the fact that people had to visit their physicians in order to register with a specific PHC physician. It remains to be seen whether the high level of new attendances will remain in the following year or whether this is just a temporary situation.
