Human infections by Hymenolepis diminuta in Europe: a case report and literature review.

We performed a review of published and gray literature of human Hymenolepis diminuta cases across Europe up to July 2022. Of all detectable publications and records, we further analyzed only those that contained demographic, clinical or epidemiological data regarding the infected subjects. Additionally, one case of hymenolepiasis in a 16-mo-old boy living in the urban part of Belgrade was included in the analysis. Published studies were based in 13/50 European countries and identified 104 laboratory-confirmed cases in total. Almost one-half (49%) of all cases originated from Mediterranean countries. Among symptomatic children, the infection most often manifested with diarrhea, abdominal pain, allergic reaction and behavioral changes. The diagnosis was made by the detection and identification of H. diminuta eggs or parts of strobila in stool samples, although cases of misdiagnosis were also reported. The parasite clearance was established with praziquantel or niclosamide, while the administration of albendazole or mebendazole led to unfavorable results. Future multicentric prospective studies focused on infection screening and the gathering of detailed sociodemographic and clinical data could provide an updated insight into the true distribution and characteristics of H. diminuta infection across Europe.

Antifungal Activity of Lavandula angustifolia Essential Oil against Candida albicans: Time-Kill Study on Pediatric Sputum Isolates.

The aim of our study was to determine the susceptibility of 15 Candida albicans sputum isolates on fluconazole and caspofungin, as well as the antifungal potential of Lavandula angustifolia essential oil (LAEO). The commercial LAEO was analyzed using gas chromatography-mass spectrometry. The antifungal activity was evaluated using EUCAST protocol. A killing assay was performed to evaluate kinetics of 2% LAEO within 30 min treatment. LAEO with major constituents' linalool (33.4%) and linalyl acetate (30.5%) effective inhibited grows of C. albicans in concentration range 0.5-2%. Fluconazole activity was noted in 67% of the isolates with MICs in range 0.06-1 µg/mL. Surprisingly, 40% of isolates were non-wild-type (non-WT), while MICs for WT ranged between 0.125-0.25 µg/mL. There were no significant differences in the LAEO MICs among fluconazole-resistant and fluconazole-susceptible sputum strains (p = 0.31) and neither among caspofungin non-WT and WT isolates (p = 0.79). The 2% LAEO rapidly achieved 50% growth reduction in all tested strains between 0.2 and 3.5 min. Within 30 min, the same LAEO concentration exhibited a 99.9% reduction in 27% isolates. This study demonstrated that 2% solution of LAEO showed a significant antifungal activity which is equally effective against fluconazole and caspofungin susceptible and less-susceptible strains.

Fungal contamination of medical students' mobile phones from the University of Belgrade, Serbia: a cross-sectional study.

The study aimed to characterize fungal contamination of medical students' mobile phones, investigate mobile phones' usage and cleaning habits, identify independent risk factors for fungal contamination, and awareness of mobile phones as a potential route of infection. In a cross-sectional study, medical students' mobile phones were sampled for possible fungal contamination. The questionnaire was used to record mobile phone usage, cleaning habits, and awareness of mobile phones as a source of infection. A total of 492 medical students were included and fungal contamination of mobile phones was confirmed in 32.11%. The most frequent fungal isolates on students' mobile phones were Candida albicans (28.5%), followed by Aspergillus niger (11.4%), and Penicillium chrysogenum (9.5%). Factors independently associated with fungal contamination of students' mobile phones were: lack of mobile phone cleaning (OR = 0.381; p < 0.001), and usage of mobile phones near patients' beds (OR = 0.571; p = 0.007). The results of this study confirmed that students who use their mobile phones in hospital wards have a higher rate of fungal contamination. The development of active surveillance and preventive strategies is needed to reduce the risk of cross-contamination and increase awareness of fungal transmission via mobile phones.

Correlation of clinical characteristics, by calculation of SCIO index, with the laboratory diagnosis of onychomycosis.

INTRODUCTION: Onychomycosis is a chronic fungal infection with increasing incidence and the global prevalence is estimated to be 5.5%. The aim of our study was to perceive objectively severity of onychomycosis by calculating Scoring Clinical Index for Onychomycosis and to correlate this index with accurate laboratory diagnosis in our patients. MATERIALS AND METHODS: The study population comprised of 417 patients with laboratory confirmed onychomycosis. For each patient, we recorded basic demographic information, site of infection, the most affected nail with onychomycosis, clinical presentation, and type of onychomycosis. The evaluation of the disease severity was based on Scoring Clinical Index for Onychomycosis which was calculated for every patient separately. Mycological identification was done by microscopy and fungal culture. RESULTS: The majority of patients had distal and lateral subungual onychomycosis (95.44%) that was localized on big toe (62.59%), with female to male ratio 1.24:1. Male patients had significantly more nails affected with onychomycosis compared with female patients (p = 0.011), while female had significantly more often onychomycosis on fingernails 2-5 (p < 0.05), and they reported significantly more often pain (p < 0.05) and esthetic problems (p < 0.05). Mean Scoring Clinical Index for Onychomycosis was 16.76. Dermatophytes were most frequently isolated (91.85%). In patients with onychomycosis caused by dermatophytes, Scoring Clinical Index for Onychomycosis had significantly higher values (p = 0.032). CONCLUSION: Comprehensive understanding of disease characteristics will allow introduction of individualized treatment plan for each patient, based on proper fungal identification and standardized method of evaluating disease severity, which could help the patient achieve a complete cure.

Coronavirus Disease 2019 (COVID-19) Epidemic and Mental Health Status in the General Adult Population of Serbia: A Cross-Sectional Study.

Since its outbreak, coronavirus disease 2019 (COVID-19) has rapidly spread throughout the world. The Serbian government declared a state of emergency on 15 March 2020, implementing some of Europe's strictest measures to combat the pandemic. The aim of this study was to determine the impact of the COVID-19 epidemic on the mental health of the general adult Serbian population and to identify associated factors during the state of emergency and lockdown. Data were collected with a snowball sampling method between 23 March and 25 April 2020, by using an online questionnaire. Multiple ordinal regression was performed to establish the associations between socio-demographic characteristics, self-estimated health status, and depression, anxiety, and stress. Out of 1057 participants included in the study, 28.9%, 36.9%, and 38.1% reported moderate to severe depression, anxiety, and stress symptoms. Uneasiness related to COVID-19 news, the feeling of helplessness, likeliness of impending death, and presence of COVID-19 symptoms were associated with higher depression, anxiety, and stress scores. Current smoking status was associated with a higher risk of depression and stress. Students had a significantly higher level of depression and stress, while older age was protective against anxiety and stress. Higher socioeconomic status was significantly associated with lower levels of depression, anxiety, and stress.

Changes in disease burden in Poland between 1990-2017 in comparison with other Central European countries: A systematic analysis for the Global Burden of Disease Study 2017.

BACKGROUND: Systematic collection of mortality/morbidity data over time is crucial for monitoring trends in population health, developing health policies, assessing the impact of health programs. In Poland, a comprehensive analysis describing trends in disease burden for major conditions has never been published. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides data on the burden of over 300 diseases in 195 countries since 1990. We used the GBD database to undertake an assessment of disease burden in Poland, evaluate changes in population health between 1990-2017, and compare Poland with other Central European (CE) countries. METHODS: The results of GBD 2017 for 1990 and 2017 for Poland and CE were used to assess rates and trends in years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted life years (DALYs). Data came from cause-of-death registration systems, population health surveys, disease registries, hospitalization databases, and the scientific literature. Analytical approaches have been used to adjust for missing data, errors in cause-of-death certification, and differences in data collection methodology. Main estimation strategies were ensemble modelling for mortality and Bayesian meta-regression for disability. RESULTS: Between 1990-2017, age-standardized YLL rates for all causes declined in Poland by 46.0% (95% UI: 43.7-48.2), YLD rates declined by 4.0% (4.2-4.9), DALY rates by 31.7% (29.2-34.4). For both YLLs and YLDs, greater relative declines were observed for females. There was a large decrease in communicable, maternal, neonatal, and nutritional disease DALYs (48.2%; 46.3-50.4). DALYs due to non-communicable diseases (NCDs) decreased slightly (2.0%; 0.1-4.6). In 2017, Poland performed better than CE as a whole (ranked fourth for YLLs, sixth for YLDs, and fifth for DALYs) and achieved greater reductions in YLLs and DALYs than most CE countries. In 2017 and 1990, the leading cause of YLLs and DALYs in Poland and CE was ischaemic heart disease (IHD), and the leading cause of YLDs was low back pain. In 2017, the top 20 causes of YLLs and YLDs in Poland and CE were the same, although in different order. In Poland, age-standardized DALYs from neonatal causes, other cardiovascular and circulatory diseases, and road injuries declined substantially between 1990-2017, while alcohol use disorders and chronic liver diseases increased. The highest observed-to-expected ratios were seen for alcohol use disorders for YLLs, neonatal sepsis for YLDs, and falls for DALYs (3.21, 2.65, and 2.03, respectively). CONCLUSIONS: There was relatively little geographical variation in premature death and disability in CE in 2017, although some between-country differences existed. Health in Poland has been improving since 1990; in 2017 Poland outperformed CE as a whole for YLLs, YLDs, and DALYs. While the health gap between Poland and Western Europe has diminished, it remains substantial. The shift to NCDs and chronic disability, together with marked between-gender health inequalities, poses a challenge for the Polish health-care system. IHD is still the leading cause of disease burden in Poland, but DALYs from IHD are declining. To further reduce disease burden, an integrated response focused on NCDs and population groups with disproportionally high burden is needed.

Low Back Pain among Medical Students in Belgrade (Serbia): A Cross-Sectional Study.

Aim: To examine the prevalence of low back pain, to identify self-perceived triggers of low back pain, and to investigate the impact of perceived pain on the daily activities and mood among medical students. Methods: This cross-sectional study enrolled 459 fourth year students at the Faculty of Medicine in Belgrade during December 2014. The anonymous questionnaire was used for data collection. In data analysis, the chi-square test and t-test were used. Results: The lifetime prevalence of low back pain was 75.8%, 12-month prevalence 59.5%, and point prevalence 17.2%. Chronic low back pain was experienced by 12.4% of the students. Both the lifetime (p=0.001) and the 12-month (p=0.001) low back pain prevalence rates were significantly higher among female medical students. Mental stress during an exam period (p=0.001), sitting at the university (p=0.002), fatigue (p=0.043), improper body posture (p=0.005), and lack of exercise (p=0.001) as self-perceived triggers of low back pain were significantly more often reported by female students, compared to males. Regarding daily functioning, the experience of low back pain mostly affects students sleeping (14.6%) and walking (12.0%). Conclusions: The prevalence of LBP is high among Belgrade medical students and significantly affects their everyday functioning.

Serbian medical students' fertility awareness and attitudes towards future parenthood.

OBJECTIVES: Medical students represent a group particularly at risk of involuntary childlessness due to their highly demanding careers and university curriculum. The aim of this study was to investigate Serbian medical students' attitudes towards future parenthood and their awareness of fertility issues. METHODS: A cross-sectional study was conducted among fourth year students at the Faculty of Medicine, University of Belgrade, Serbia, between 12 and 16 December 2016. Data were collected through an anonymous 56-item validated questionnaire, translated into the Serbian language. The participation rate was 87.1%. RESULTS: More than 95% of students, regardless of gender, wanted to have children in the future; most indicated three as the desired number of children. Both genders equally rated the importance of having children. Women rated significantly higher the likelihood of IVF treatment or child adoption if faced with infertility (both p = .001). All students wanted to have their first child before the age of 35 years. Knowledge about the age-related decline in female fertility was not satisfactory. Women found it more important to have children when they felt sufficiently mature, were in a stable relationship, were financially secure, had completed their studies, were not too old to have children, and had access to childcare, although these prerequisites were rated highly by both genders. CONCLUSION: Serbian medical students greatly value and have a positive perception of future parenthood. Appropriate education is needed, however, because of their inadequate knowledge of the age-related decline in female fertility.

Attitudes Toward Medical Cannabis Legalization Among Serbian Medical Students.

BACKGROUND: Currently, medical cannabis polices are experiencing rapid changes, and an increasing number of nations around the world legalize medical cannabis for certain groups of patients, including those in Serbia. OBJECTIVES: To determine medical students' attitudes toward medical cannabis legalization and to examine the factors influencing their attitudes. METHODS: Fourth-year medical students at the Faculty of Medicine, University of Belgrade, had participated in a cross-sectional study. Data were collected by an anonymous questionnaire. RESULTS: Overall, 63.4% students supported medical cannabis legalization, and only 20.8% supported its legalization for recreational use. Students who previously used marijuana (p <.001) and alcohol (p =.004) were significantly more in favor of medical cannabis legalization compared with students who never used them. Support for marijuana recreational use was also related to prior marijuana (p <.001) and alcohol consumption (p =.006). Only cancer (90.4%) and chronic pain (74.2%) were correctly reported approved medical indications by more than half the students. Students who supported medical cannabis legalization showed better knowledge about indications, in contrast to opponents for legalization who showed better knowledge about side effects. Beliefs that using medical cannabis is safe and has health benefits were correlated with support for legalization, and previous marijuana and alcohol use, while beliefs that medical cannabis poses health risks correlated most strongly with previous marijuana use. Conclusions/Importance: The medical students' attitudes toward medical cannabis legalization were significantly correlated with previous use of marijuana and alcohol, knowledge about medical indications and side effects, and their beliefs regarding medical cannabis health benefits and risks.

Epidemiology of onychomycosis in Serbia: a laboratory-based survey and risk factor identification.

Onychomycosis is a fungal infection of the fingernails and/or toenails caused by dermatophytes, yeasts and non-dermatophyte moulds. The epidemiology of onychomycosis in Serbia is yet to be fully established. This epidemiological study was aimed at evaluating the epidemiology of onychomycosis in a sample of the Serbian patients at risk of onychomycosis, to determine the fungal aetiological agents and to identify the possible risk factors. The study population included 374 patients from six centres in Serbia with suspected onychomycosis. Demographic data, data about comorbidities, lifestyle, clinical aspects of onychomycosis, trauma, excessive perspiration and personal and family history of previous onychomycosis were studied. Laboratory confirmation of diagnosis was done by direct microscopy, fungal culture and PCR. Diagnosis of onychomycosis was confirmed in 50.8% of patients, who tested positive to at least one laboratory test (direct microscopy, fungal culture or PCR). Trichophyton rubrum was predominant both on toenails (85.98%) and on fingernails (38.46%). Independent risk factors for onychomycosis were: old age (OR = 2.285; P < 0.001), family history of previous onychomycosis and/or tinea pedis (OR = 2.452; P = 0.005), excessive perspiration (OR = 2.165; P = 0.002) and higher degree of hyperkeratosis (OR = 1.755; P = 0.020). This is a first epidemiological study of onychomycosis from Serbia.

Psychosocial Stress and Risk of Myocardial Infarction: A Case-Control Study in Belgrade (Serbia).

BACKGROUND: The purpose of this study was to investigate which psychosocial risk factors show the strongest association with occurrence of myocardial infarction (MI) in the population of Belgrade in peacetime, after the big political changes in Serbia. METHODS: A case-control study was conducted involving 154 consecutive newly diagnosed patients with MI, and 308 controls matched by gender, age, and place of residence. RESULTS: According to conditional logistic regression analysis, after adjustment for conventional coronary risk factors, the odds ratios (95% confidence intervals) for work-related stressful events, financial stress, deaths and diseases, and general stress were 3.78 (1.83-7.81), 3.80 (1.96-7.38), 1.69 (1.03-2.78), and 3.54 (2.01-6.22), respectively. Among individual stressful life events, the following were independently related to MI: death of a close family member, 2.21 (1.01-4.84); death of a close friend, 42.20 (3.70-481.29); major financial problems, 8.94 (1.83-43.63); minor financial problems, 4.74 (2.02-11.14); changes in working hours, 4.99 (1.64-15.22); and changes in working conditions, 30.94 (5.43-176.31). CONCLUSIONS: During this political transition period , stress at work, financial stress, and stress in general as they impacted the population of Belgrade, Serbia were strongly associated with occurence of MI.

Trends in mortality rates from coronary heart disease in Belgrade (Serbia) during the period 1990-2010: a joinpoint regression analysis.

BACKGROUND: Coronary heart disease (CHD) causes an estimated 7 million deaths worldwide each year. In the last few decades, mortality from CHD has been decreasing in many countries. The aim of this study was to analyze the trends of mortality from CHD and myocardial infarction (MI) in the population of Belgrade during the period 1990-2010. METHODS: Mortality data for CHD and MI were obtained from the Municipal Institute of Statistics in Belgrade and used to calculate age- and sex-specific and age-adjusted mortality rates. Joinpoint regression analysis was used to estimate annual percent changes (APCs) in mortality and to identify points in time where significant changes in trend occur. RESULTS: Trends in CHD mortality rates showed significant decline in men during the period studied (APC -0.5%, no joinpoints detected), but no significant change among women (APC +0.4%, no joinpoints detected). While we observed significant declines in CHD mortality in men aged 35-44, 55-64 and 65-74 and women aged 55-64, there was a significant increase in mortality in men aged ≥85 and women aged 75-84 and ≥85. Trends in MI mortality rates showed similar patterns in both genders, with a significant decline from the mid-1990s. Significant decline in MI mortality was observed in almost all age groups, except the two oldest (75-84 and ≥85) in women population. CONCLUSIONS: Given that CHD and MI mortality trends showed different patterns during the period studied, especially in women, our results imply that further observation of trend is needed.
