The article describes the use of the last-resort carbapenem antibiotic imipenem in combination with relebactam, a novel b-lactamase inhibitor, in the treatment of ventilator-associated pneumonia developing after SARS-CoV-2 infection in a young pregnant patient. The introduction briefly describes the mechanism and spectrum of activity of the antibiotic, including its dosage.

Objectives This study aims to analyze the effect of intravenous administration of tranexamic acid (TA) on reducing the risk of revision for acute and delayed periprosthetic joint infection (PJI) after primary total knee replacement (TKR). Patients and methods This prospective observational cohort study included 1,529 TKRs (396 males, 1,133 females; mean age 67.8 years; range, 44 to 85.1 years) performed between January 2003 and October 2017. We analyzed the revision rate for acute and delayed PJI in a group of 787 TKRs with preoperatively intravenously administered TA (TA group) in comparison with a group of 742 TKRs without administration of TA (non-TA group). Multiple logistic regression analysis was used to evaluate significant predictors of TKR revision for acute and delayed PJI. Results Revision surgery due to PJI was recorded in one patient in the TA group and eight patients in the non-TA group. Cumulative revision rate of TKR was significantly lower in the TA group (0.13% vs. 1.08%, hazard ratio 0.113; 95% confidence interval [CI] 0.0147-0.937; p=0.043). Multivariate logistic regression analysis confirmed two predictors of revision: being aged over 75 years at the time of primary surgery (odds ratio [OR] 8.464; 95% CI: 2.016-35.54; p=0.004) and male gender (OR: 7.9; 95% CI: 1.879-33.26; p=0.005). The use of TA was shown as the significant protective factor (OR: 0.109; 95% CI: 0.0128-0.929; p=0.043). Conclusion We have found a lower cumulative revision rate of TKR for acute and delayed PJI when TA was used. We think that the preoperative intravenous use of TA may be an effective, safe and inexpensive method for the prevention of PJI.

Inanimate surfaces are often referred to as nosocomial bacterial reservoirs and represent an important vector in the process of spreading pathogens to patients. Most gram-negative rods can survive on inanimate surfaces for several months. The aim of this study is to determine the prevalence and resistance of gram-negative bacteria isolated from the inanimate surfaces of two selected hospital departments. MALDI-TOF identified gram-negative rods isolated from inanimate surfaces. Antibiotic resistance was determined using a disk diffusion method, and the phenotype of resistance was determined using an inhibitory analyzer. From the inanimate surfaces, 98 strains of gram-negative nosocomial bacteria were identified by the MALDI-TOF MS. The most frequently isolated bacterium occurring in both departments was Pseudomonas aeruginosa (n = 33), followed by Acinetobacter baumannii (n = 20) and Enterobacter cloacae (n = 14). The most common phenotypic type of resistance in both departments was ampicillin resistance—AmpC (n = 38), then production of extended-spectrum β-lactamase (ESBL) (n = 33), followed by SHV-1 (n = 11), TEM-1 (n = 11), and fluoroquinolone resistance—Qnr (n = 22). The nosocomial important enzymes capable of hydrolyzing carbapenems, OXA-48 and metallo-β-lactamases, were confirmed in 12 and 2 cases, respectively. The results of our study prove that inanimate surfaces in hospitals are a reservoir of resistant gram-negative bacteria, which directly threaten hospitalized patients.

This work aimed to determine the representation and resistance of bacteria belonging to the genus Staphylococcus and Enterococcus on inanimate surfaces of two selected workplaces of the University Hospital of L. Pasteur in Košice (UHLP) and to investigate their importance in the hospital environment. The men's ward of the Department of Internal Medicine (DIM) and the Department of Anaesthesiology and Intensive Care (DAIC) were chosen.Using sterile sampling kits, a total of 182 swabs were collected from the inanimate surfaces of both UHLP workplaces. The swabs were then transported to a microbiological laboratory and inoculated onto sterile culture media (blood agar containing 5% ram erythrocytes). After culturing (24-48 hours, in a thermostat at constant temperature 37 °C), bacterial colonies were identified by mass spectrometry on a MALDI TOF MS. Bacteria belonging to the genera Staphylococcus and Enterococcus were subsequently separated from the spectrum of identified bacteria. Nosocomial significant strains of staphylococci (Staphylococcus epidermidis, Staphylococcus haemolyticus, Staphylococcus aureus) and all isolated enterococci were subjected to susceptibility testing for selected antibiotics using the disk diffusion method - E-tests.Several members of the genus Staphylococcus were identified from the inanimate surfaces of both workplaces. These were mainly coagulase-negative strains - Staphylococcus epidermidis (45), Staphylococcus capitis (34), Staphylococcus haemolyticus (20), Staphylococcus hominis (45), Staphylococcus pasteuri (2), Staphylococcus sroph (1), Staphylococcus simulans (3), and Staphylococcus warneri (4). Staphylococcus aureus strains were also identified (2). Nosocomial significant isolates were tested for susceptibility to the antibiotics cefoxitin (FOX) and oxacillin (OXA). Two members of the genus Enterococcus - Enterococcus faecium (7) and Enterococcus faecalis (8) were isolated. All strains were subject to vancomycin susceptibility testing using the disk method.

The Slovakian test case Toward the end of 2020, Slovakia decided that it would test and then isolate positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases among its entire population of 5.5 million, and more than 50,000 positive cases were found during a rapid antigen testing campaign. Pavelka et al. analyzed the data and found that in 41 counties before and after the two rounds of testing, infection prevalence declined by about 80% (see the Perspective by Garca-Fiana and Buchan). They also used the data to test a microsimulation model for one county. Quarantine of the whole household after a positive test was essential to achieving a large reduction in prevalence. Since Autumn 2020, transmission in Slovakia has rebounded, despite other interventions, because high-intensity testing was not sustainable. Science, this issue p. 635; see also p. 571, A nationwide testing effort in Slovakia during late 2020 reduced infection prevalence by more than 80% in 2 weeks but could not be sustained., Slovakia conducted multiple rounds of population-wide rapid antigen testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in late 2020, combined with a period of additional contact restrictions. Observed prevalence decreased by 58% (95% confidence interval: 57 to 58%) within 1 week in the 45 counties that were subject to two rounds of mass testing, an estimate that remained robust when adjusting for multiple potential confounders. Adjusting for epidemic growth of 4.4% (1.1 to 6.9%) per day preceding the mass testing campaign, the estimated decrease in prevalence compared with a scenario of unmitigated growth was 70% (67 to 73%). Modeling indicated that this decrease could not be explained solely by infection control measures but required the addition of the isolation and quarantine of household members of those testing positive.

Background: Health characteristics associated with uric acid (UA) in the Roma minority remain less well known. The study sought to determine the ethnicity- and sex-specific associations of serum UA with health factors in Eastern Slovakian Roma and non-Roma populations. Methods: Data from the comparative cross-sectional HepaMeta study conducted in Slovakia in 2011 were used. The study enrolled 452 Roma subjects (35.2% men) and 403 non-Roma individuals (45.9% men) aged 18–55 years. Results: All study parameters differed between the sexes in both the Roma and non-Roma participants (p &lt, 0.05). UA was related to sex with odds ratio for female sex 0.873, 95% CI 0.853–0.893 (p &lt, 0.0001) per 10-unit increase of UA. Average level of UA ± standard deviation was lower in Roma than in non-Roma (226.54 ± 79.8 vs. 259.11 ± 84.53 umol/L, p &lt, 0.0001). The Roma population presented with greater levels of high-sensitivity C-reactive protein (hsCRP) (3.07 ± 4 mg/L vs. 1.98 ± 2.83 mg/L, 0.0001) and ferritin in Roma males (403.78 ± 391.84 vs. 302.67 ± 236.26 mg/L, 0.0001). Conclusions: Serum UA is sex- and ethnicity specific. Elevated levels of hsCRP and ferritin particularly in Roma males can reflect low-grade systemic inflammation and thus serve as a marker of an increased cardiovascular risk.

Background: The Roma population is one of the major marginalized groups in Europe, having higher incidence of all spectrums of disease and a shorter life expectancy. Yet, the reasons for higher morbidity and its exact prevalence were not properly studied. Objectives: The objective of our study was to compare the frequency of metabolic syndrome (MetS) in Roma people to the non-Roma population in Slovakia, and to compare levels of uric acid and its correlation with components of metabolic syndrome. Methods: A group of 452 Roma people aged 18&ndash, 55 years, was compared to a control group of 403 non-Roma people. The data were obtained by questionnaire, anthropometric measures, and analyzed blood and urine samples Results: The prevalence of MetS was significantly higher among Roma participants (131, 29.6%) compared with non-Roma participants (80, 20.1%), p = 0.001. Roma people significantly more often fulfilled obesity and low high-density lipoprotein (HDL) criteria of MetS (257, 58.9% vs. 180, 45.8%, p &lt, 0.0001, and 312, 70.0% vs. 140, 34.9%, p &lt, 0.0001). There was no difference in the triacylglycerols (TG), glycemia or blood pressure (BP) criteria of MetS. The Roma also presented with greater levels of high sensitivity C-reactive protein (hs-CRP). Baseline levels of uric acid (UA) among the Roma population were significantly lower compared with the majority population (226.54 &plusmn, 79.8 vs. 259.11 &plusmn, 84.53) (p &lt, 0.001). The levels of UA significantly correlated with fulfilled criteria of MetS. Univariate regression showed that UA is a significant predictor of MetS in the whole cohort (unadjusted odds ratio (OR) 1.005, 95% CI 1.004&ndash, 1.007, p &lt, 0.0001) also after the adjustment for age, sex, and ethnicity (adjusted OR 1.008, 95% CI 1.005&ndash, 1.010, 0.0001). Conclusions: We were able to show that prevalence of MetS among the Roma is higher than in the majority population. Moreover, the uric acid levels are significantly lower in the Roma group as well as when it comes to a cohort with MetS. Levels of UA, besides others, depend on ethnicity, age, and sex.

Hepatitis E infection is one of the most frequent causes of acute hepatitis in the world. Currently five human genotypes with different geographical distributions and distinct epidemiologic patterns are identified. In Slovakia, only rare cases of hepatitis E have been reported in past years. Because the most important risk factors associated with HEV infection include consumption of contaminated pork meat and poor hygienic standards, the aim of the study was to evaluate the prevalence of anti-HEV total antibodies and the main risk factors for HEV in the population living in separated and segregated Roma settlements (n = 195), which represent places with increased risk of infection in Slovakia and to compare it with the prevalence in the general population (n = 69). Of 264 respondents included in the study, 47 (17.8%) showed positivity for anti-HEV antibodies, 42 of whom were Roma (21.5%, n = 195) and 5 (7.2%, n = 69) non-Roma. The population living in Roma settlements lives in poorer conditions and are at higher risk of HEV in comparison to the general population. However, differences in living conditions within the settlements do not contributed to lower risk of HEV antibody prevalence between Roma living in settlements.

The lifestyle, health and social status of the Roma are generally below the standards characteristic for the non-Roma population. This study aimed to find out the seropositivity to Toxoplasma gondii (T. gondii) in the population of Roma living in segregated settlements and to compare it with the prevalence of antibodies in the non-Roma population from the catchment area of eastern Slovakia. The seroprevalence of antibodies to T. gondii was significantly higher in the Roma group (45.0%) than in non-Roma inhabitants (24.1%). A statistically significant difference was also recorded between the two non-Roma groups in the study, 30.4% of those from the catchment area and 19.7% from the non-catchment area were seropositive. Univariate logistic regression confirmed poverty and higher age to be significant risk factors influencing the seropositivity to T. gondii. Of the clinical symptoms analyzed in the study, only muscle and back pain were associated with seropositivity to T. gondii. The close contact of Roma with an environment contaminated by different infectious agents and the insufficient hygiene, lower level of education, poverty, lack of water and household equipment and high number of domestic animals increase the risk of infectious diseases in the Roma settlements and subsequently the spread of communicable diseases at the national or even international level.

Trichinellosis and cystic and alveolar echinococcosis are serious parasitic diseases transmissible between animals and humans. Moreover, alveolar echinococcosis is considered one of the most dangerous of human helminthoses. Roma communities are particularly numerous in Central and Eastern Europe. They are often concentrated in economically undeveloped regions and live in segregated localities with unsatisfactory housing and sanitary conditions. The study aimed to find out the seroprevalence of Trichinella and Echinococcus infections in the Roma population of segregated settlements and to compare it with the seropositivity of the non-Roma population of eastern Slovakia. Out of 823 samples, three sera showed seropositivity to Trichinella in the ELISA (Enzyme-linked immunosorbent assay) test. Subsequent Western blot reaction (WB) confirmed seropositivity in two Roma women. ELISA seropositivity to E. multilocularis was recorded in six persons (0.73%), and five (0.61%) respondents were seropositive to E. granulosus, but WB confirmed the presence of antibodies to Echinococcus spp. in one Roma participant. Positive persons suffered from unspecific clinical symptoms; Trichinella-positive persons reported headache, cough, fatigue, and muscle pain. The Echinococcus-positive participant suffered from headache and back pain. The study showed that the worse living conditions of the Roma community did not significantly influence the occurrence of Trichinella and Echinococcus infections in this minority.

BACKGROUND Multiple studies have recently proposed the lowering of upper limit of normal (ULN) for alanine aminotransferase (ALT) to improve the diagnostic sensitivity for viral hepatitides and metabolic syndrome (MS). We have tried to validate some of the proposed ULNs in the diagnosis of MS. METHODS We used data from the HepaMeta Study conducted in 2011 in Slovakia, which explored the prevalence of MS in eastern Slovakia. Patients were tested for the criteria of MS and ALT. Different, previously published, ALT cutoffs were then used to calculate odds' ratios, sensitivity, specificity, and accuracy of MS and its components. RESULTS Manufacturers' recommended ULN used in our institution (0.8 µkat/l, 47 U/l for men and 0.6 µkat/l, 35 U/l for women) failed to predict any significant risk of MS. Lowered cutoff (72% of the original ULN) identified the patients with the highest age-adjusted probability of MS (odds ratio 3.194, 95% confidence interval 1.398-7.295). ALT was significantly associated with elevated levels of triacylglycerols, hyperglycemia, and obesity. CONCLUSION In patients with MS, one must consider liver involvement if the patient has ALT levels in the upper third of the reference range. There is the need for discussion about the feasibility of lower ALT ULN in clinical practice.

Background: Obesity and overweight are major contributors to the global burden of chronic diseases and disability in both majority and minority populations. Methods: Data from the cross-sectional population-based HepaMeta study conducted in Slovakia in 2011 were used. The sample comprised a total of 452 Roma. Measurements of special bioactive mediators were taken in final groups consisting of 63 male Roma respondents (mean age = 32.59; SD=8.63) and 117 female Roma respondents (mean age = 34.55; SD=8.35). Respondents were divided into three groups: those with normal weight, those with overweight and obese. Values for anthropometric parameters, lipids parameters, C-reactive protein, TNF-α, IL-6, leptin, and adiponectin were determined. Results: 27.6% of examined Roma females and 26.9% of males were overweight. Obesity (BMI>30.0 kg/m2) appeared in a higher proportion of males (28.8%) compared with female (26.5%). Mean levels of total cholesterol, triacylglycerol and LDL-cholesterol were significantly elevated in the overweight and obese subjects compared to normal-weight Roma respondents. The relation was reversed for HDL-C level, with significantly decreased levels in both male and female obese Roma (p

This paper presents a web based educational video-clips exhibition created to share various archived lectures for medical students, health care professionals as well as for general public. The presentation of closely related topics was developed as video gallery and it is based solely on free or open source tools to be available for wide academic and/or non-commercial use. Even if the educational video records can be embedded in any websites, we preferred to use our faculty’s portal, which should be a central point to offer various multimedia educational materials. The system was integrated and tested to offer open access to infectology lectures that were captured and archived from live-streamed sessions and from videoconferences.

In our study, we examined 91 fecal samples from five different groups of people containing HIV patients, hemodialysis patients, kidney transplant recipients, immunocompetent humans without clinical signs, and humans with suspected cryptosporidiosis. The purpose of our study was to determine species and genotype composition of representatives of Cryptosporidium spp. using PCR analysis of small subunit ribosomal RNA gene and 60-kDa glycoprotein gene and examine their phylogenetic relationship. In HIV-positive/AIDS-infected group of patients and in hemodialysis patients, no presence of Cryptosporidium species was detected. In two kidney transplant recipients, we detected species/genotypes Cryptosporidium parvum IIaA13G1T1R1 (KT355488) and Cryptosporidium hominis IaA11G2R8 (KT355489) and in two immunocompetent patients with clinical symptoms, we identified Cryptosporidium muris and C. hominis IbA10G2T1 (KT355490). In the group of healthy immunocompetent individuals without clinical signs, we identified species/genotype C. hominis IbA11G2 (KT355491) in one sample.

SUMMARY Background: We aimed to study the occurrence of Chlamydia trachomatis infection in the population living in Roma settlements and to compare the obtained results with the prevalence in the majority population. Methods: We examined 340 people for the presence of bacterium C. trachomatis, 208 of them were Roma (66 men, 142 women) and 132 were from the majority population (75 men, 57 women). Respondents were aged 18–55 years (mean age = 33.44, STD = 9.57). The occurence of C. trachomatis was detected by direct proof of the pathogen by polymerase chain reaction (PCR). Results: Of 340 respondents included in the study, 22 (6.5%) showed positivity for C. trachomatis infection, 15 of them were Roma (7.2%) and 7 non-Roma (5.3%). The highest positivity was detected in Roma women (8.5%), while positivity in both non-Roma women and men was 5.3%, and in Roma men 4.5%. We did not confirm any significant contribution of age, gender or ethnicity to the occurrence of C. trachomatis infection. Conclusions: Despite the increased number of people with risk factors in the Roma community, no significant difference in the occurrence of C. trachomatis infection was found. Neither age nor gender contributes to the probability of C. trachomatis infection. Nevertheless, there are other health consequences which might be more pronounced among the population living in Roma settlements due to barriers to the health care and their lower ability to benefit from health care services provided.

SUMMARY Background: Roma represent one of the largest and oldest minorities in Europe. Health of many of them, particularly those living in settlements, is heavily compromised by poor dwelling, low educational level, unemployment, and poverty rooted in generational poverty, segregation and discrimination. The cross-sectional population-based study using community based approach aimed to map the prevalence of viral hepatitis B/C and metabolic syndrome in the population living in separated and segregated Roma settlements and to compare it with the occurrence of the same health indicators in the majority population, considering selected risk and protective factors of these health indicators. Methods: The sample consisted of 452 Roma (mean age = 34.7; 35.2% men) and 403 non-Roma (mean age = 33.5; 45.9% men) respondents. Data were collected in 2011 via questionnaire, anthropometric measures and analysed blood and urine samples. A methodology used in the study as well as in the following scientific papers is described in the Methods section (i.e. study design, procedures, samples, methods including questionnaire, anthropometric measurements, physical measurements, blood and urine measurements). Conclusions: There are regions of declining prosperity due to high unemployment, long-term problems with poverty and depleted resources. Populations living in these areas, i.e. in Central and Eastern Europe in Roma settlements, are at risk of poverty, social exclusion and other factors affecting health. Therefore, we should look for successful long-term strategies and tools (e.g. Roma mediators, terrain work) in order to improve the future prospects of these minorities.

Roma constitute the largest ethnic minority in Europe and the second largest minority in Slovakia. Their health problems originate mainly from their low socioeconomic status, certain cultural aspects and their health-threatening lifestyle as well as the psycho-social burden arising from poverty and frequent migration. Evaluation of glucose, albumin, triacylglycerol (TAG) and low density lipoprotein cholesterol (LDL-C) concentrations did not reveal any clue about the presumed deteriorated health of the Roma population. Higher proportions of subjects with elevated serum total cholesterol were found in Roma women as compared to both control groups of women (p = 0.027, p = 0.006) and in Roma men as compared to the male control group living in standard conditions. Only the low level of HDL-cholesterol gives a glimpse of their deteriorated health. Significantly lower levels of serum HDL-C were reported in Roma men and women compared to the respondents in both control groups with a p value of p < 0.001. Comparing the ratio of LDL-C/HDL-C yielded significant differences between the number of physiological values in Roma men and men from the control group 1 (p = 0.022) in favour of the control group. When comparing the number of people with physiological values of cholesterols and with worsening TAG parameters at the same time, the increased risk of Roma men compared with men from the control group 1 became evident, with a level of significance of p = 0.023. Evaluation of urine samples pointed to significantly higher concentrations of urinary protein in Roma women compared with women in the control group 1 (p = 0.012).
