The current epidemic of a new coronavirus disease
(COVID-19), caused by a novel coronavirus (2019-nCoV),
recently officially named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has ...reopened the issue
of the role and importance of coronaviruses in human pathology (1-5). This epidemic definitively confirms that this
heretofore relatively harmless family of viruses, Coronaviridae, includes major pathogens of epidemic potential. The
COVID-19 epidemic has clearly demonstrated the power
of infectious diseases, which have been responsible for
many devastating epidemics throughout history. The epidemiological potential of emerging infectious diseases, especially zoonoses, is affected by numerous environmental,
epidemiological, social, and economic factors (6,7). Emerging zoonoses pose both epidemiological and clinical challenges to health care professionals.
The Deputy Prime Minister and Minister of the Interior was chosen to lead the headquarters, whose members are the Director of the Croatian Institute of Public Health, the Director of the Croatian ...Institute of Emergency Medicine, and the Director of the Dr Fran Mihaljević University Hospital for Infectious Diseases (UHID), who is also the President of the Croatian Society for Biosafety and Biosecurity. The Minister of Health issued the decision to proclaim the threat of a COVID-19 epidemic as an administrative measure, which does not indicate the degree of the threat but permits the Minister to mobilize all the resources in the health care system, redeploying ID physicians, other health care workers (HCWs) and equipment, in order to improve the administration of the health care system. On the national level, no increase in the incidence of COVID-19 was experienced in the post-earthquake period, as shown in Figure 1. ...owing to the chronic shortage of medical personnel throughout the entire health care system, particularly now when the demands are increasing, we are being expected to make great sacrifices in order to provide the best possible care to all citizens.
Looking back on the onset of the pandemic
Exactly two years ago, we published an editorial in the Croatian Medical Journal discussing a global threat from a new
coronavirus epidemic caused by the ...SARS-CoV-2 virus,
which began in China at the end of 2019 and soon spread
around the world (1). The first case of COVID-19 in Croatia
was recorded on February 25, 2020, while the editorial was
being written. On that occasion, we warned of the danger
of the rapid spread and pathogenic potential of the novel
coronavirus, the need for the constant monitoring of respiratory pathogens with high epidemic potential, as well
as of the importance of developing vaccines and antiviral
drugs rapidly to combat this and similar viruses.
Digital health technologies (DHTs), such as electronic health records and prescribing systems, are transforming health care delivery around the world. The quality of information in DHTs is key to the ...quality and safety of care. We developed a novel clinical information quality (CLIQ) framework to assess the quality of clinical information in DHTs.
This study explored clinicians' perspectives on the relevance, definition, and assessment of information quality dimensions in the CLIQ framework.
We used a systematic and iterative eDelphi approach to engage clinicians who had information governance roles or personal interest in information governance; the clinicians were recruited through purposive and snowball sampling techniques. Data were collected using semistructured online questionnaires until consensus was reached on the information quality dimensions in the CLIQ framework. Responses on the relevance of the dimensions were summarized to inform decisions on retention of the dimensions according to prespecified rules. Thematic analysis of the free-text responses was used to revise definitions and the assessment of dimensions.
Thirty-five clinicians from 10 countries participated in the study, which was concluded after the second round. Consensus was reached on all dimensions and categories in the CLIQ framework: informativeness (accuracy, completeness, interpretability, plausibility, provenance, and relevance), availability (accessibility, portability, security, and timeliness), and usability (conformance, consistency, and maintainability). A new dimension, searchability, was introduced in the availability category to account for the ease of finding needed information in the DHTs. Certain dimensions were renamed, and some definitions were rephrased to improve clarity.
The CLIQ framework reached a high expert consensus and clarity of language relating to the information quality dimensions. The framework can be used by health care managers and institutions as a pragmatic tool for identifying and forestalling information quality problems that could compromise patient safety and quality of care.

•Burkholderia gladioli was identified as a cause of healthcare-associated bacteremia.•The investigation traced to the contaminated multidose vials with saline solution.•Isolates from blood and saline ...showed the same susceptibility patterns.•Pulsed-field gel electrophoresis (PFGE) was used to genotype the strains.•PFGE profile of all B. gladioli isolates demonstrated clonal relatedness.
Burkholderia gladioli has been associated with infections in patients with cystic fibrosis, chronic granulomatous disease, and other immunocompromising conditions. The aim of this study was to better depict the outbreak of healthcare-associated bacteremia caused by B. gladioli due to exposure to contaminated multidose vials with saline solutions.
An environmental and epidemiologic investigation was conducted by the Infection Prevention and Control Team (IPCT) to identify the source of the outbreak in three Croatian hospitals.
During a 3-month period, 13 B. gladioli bacteremia episodes were identified in 10 patients in three Croatian hospitals. At the time of the outbreak, all three hospitals used saline products from the same manufacturer. Two 100-ml multidose vials with saline solutions and needleless dispensing pins were positive for B. gladioli. All 13 bacteremia isolates and two isolates from the saline showed the same antimicrobial susceptibility patterns and pulsed-field gel electrophoresis profile, demonstrating clonal relatedness.
When an environmental pathogen causes an outbreak, contamination of intravenous products must be considered. Close communication between the local IPCT and the National Hospital Infection Control Advisory Committee is essential to conduct a prompt and thorough investigation and find the source of the outbreak.

Many relatively common chronic inflammatory skin diseases manifest on the face (seborrheic dermatitis, rosacea, acne, perioral/periorificial dermatitis, periocular dermatitis, etc.), thereby ...significantly impairing patient appearance and quality of life. Given the yet unexplained pathogenesis and numerous factors involved, these diseases often present therapeutic challenges. The term “microbiome” comprises the totality of microorganisms (microbiota), their genomes, and environmental factors in a particular environment. Changes in human skin microbiota composition and/or functionality are believed to trigger immune dysregulation, and consequently an inflammatory response, thereby playing a potentially significant role in the clinical manifestations and treatment of these diseases. Although cultivation methods have traditionally been used in studies of bacterial microbiome species, a large number of bacterial strains cannot be grown in the laboratory. Since standard culture-dependent methods detect fewer than 1% of all bacterial species, a metagenomic approach could be used to detect bacteria that cannot be cultivated. The skin microbiome exhibits spatial distribution associated with the microenvironment (sebaceous, moist, and dry areas). However, although disturbance of the skin microbiome can lead to a number of pathological conditions and diseases, it is still not clear whether skin diseases result from change in the microbiome or cause such a change. Thus far, the skin microbiome has been studied in atopic dermatitis, seborrheic dermatitis, psoriasis, acne, and rosacea. Studies on the possible association between changes in the microbiome and their association with skin diseases have improved the understanding of disease development, diagnostics, and therapeutics. The identification of the bacterial markers associated with particular inflammatory skin diseases would significantly accelerate the diagnostics and reduce treatment costs. Microbiota research and determination could facilitate the identification of potential causes of skin diseases that cannot be detected by simpler methods, thereby contributing to the design and development of more effective therapies.
The main aim of this pilot project was to introduce multimodal smoking cessation intervention in the hospital setting and to analyze users' satisfaction and efficacy of the intervention within six ...months post-discharge. Multimodal intervention for smoking cessation was used and it consisted of the "5 A's" model (Ask, Advice, Assess, Assist, Arrange) for behavior change, printed self-help materials for smoking cessation, and telephone counseling (one, three and six months after discharge from the hospital). The main outcome of the study was smoking status at six months. A total of 103 participants were included in this pilot project. At six-month follow-up, 49% of participants self-reported continuous non-smoking. Among the remaining participants, 20 reported smoking reduction, 19 were still smoking, and 16 participants were unable to make contact with. In the logistic regression, among all analyzed variables, only two of them were positively associated with smoking cessation after six months: participants' response that they would like to quit smoking within the next six months (B=4.688; p=0.018) and answering that they did not smoke when they were ill and bed-ridden due to illness (B=3.253; p=0.020). Satisfaction with the intervention was very high; 70% of participants rated the intervention as 'excellent'. Therefore, multimodal smoking cessation intervention can be successfully introduced at hospital setting yielding high smoking abstinence rates at six months post-discharge and high level of user satisfaction. Healthcare workers who work in hospitals should be educated so they can provide such intervention on a regular basis.
Hemorrhagic fever with renal syndrome (HFRS) is an acute zoonotic disease caused by viruses of the Orthohantavirus genus. This syndrome is characterized by renal and cardiopulmonary implications ...detectable with different biomarkers. Here, we explored the role of serum and urine levels of lipocalin-2, endothelin-1 and N-terminal pro-brain natriuretic peptide (NT-proBNP) in HFRS pathology. A total of twenty-eight patients hospitalized due to a Puumala orthohantavirus infection were included, with serum and urine samples collected on patient admission (acute phase) and discharge (convalescent phase). In comparison to healthy individuals, patients exhibited significantly higher acute-phase serum and urine levels of lipocalin-2, serum levels of endothelin-1 and serum and urine levels of NT-proBNP. Patients in the convalescent phase showed a significant decrease in urine lipocalin-2, serum endothelin-1 and serum and urine NT-proBNP levels. We recorded a strong correlation between serum levels of lipocalin-2 and endothelin-1 and urine levels of lipocalin-2 with several kidney injury markers, such as serum creatinine, urea, urine white blood cell count and proteinuria. We also demonstrated an independent correlation of serum and urine lipocalin-2 levels with acute kidney injury in HFRS. All in all, our results show an involvement of NT-proBNP, lipocalin-2 and endothelin-1 in the renal and cardiac pathology of HFRS.
The widespread use of antibiotics has been associated with the emergence of antimicrobial resistance among bacteria. 'ESKAPE' (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, ...Acintobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp.) pathogens play a major role in the rapidly changing scenario of antimicrobial resistance in the 21st century. Chloramphenicol is a broad spectrum antibiotic that was abandoned in developed countries due to its association with fatal aplastic anemia. However, it is still widely used in the developing world. In light of the emerging problem of multi-drug resistant pathogens, its role should be reassessed. Our paper reviews in vitro data on the activity of chloramphenicol against ESKAPE pathogens. Susceptibility patterns for Gram-positives were good, although less favorable for Gram-negatives. However, in combination with colistin, chloramphenicol was found to have synergistic activity. The risk-benefit related to chloramphenicol toxicity has not been analyzed. Therefore, extra precautions should be taken when prescribing this agent.
The essential role of immunoglobulin G (IgG) in immune system regulation and combatting infectious diseases cannot be fully recognized without an understanding of the changes in its N-glycans ...attached to the asparagine 297 of the fragment crystallizable (Fc) domain that occur under such circumstances. These glycans impact the antibody stability, half-life, secretion, immunogenicity, and effector functions. Therefore, in this study, we analyzed and compared the total IgG glycome—at the level of individual glycan structures and derived glycosylation traits (sialylation, galactosylation, fucosylation, and bisecting N-acetylglucosamine (GlcNAc))—of 64 patients with influenza, 77 patients with coronavirus disease 2019 (COVID-19), and 56 healthy controls. Our study revealed a significant decrease in IgG galactosylation, sialylation, and bisecting GlcNAc (where the latter shows the most significant decrease) in deceased COVID-19 patients, whereas IgG fucosylation was increased. On the other hand, IgG galactosylation remained stable in influenza patients and COVID-19 survivors. IgG glycosylation in influenza patients was more time-dependent: In the first seven days of the disease, sialylation increased and fucosylation and bisecting GlcNAc decreased; in the next 21 days, sialylation decreased and fucosylation increased (while bisecting GlcNAc remained stable). The similarity of IgG glycosylation changes in COVID-19 survivors and influenza patients may be the consequence of an adequate immune response to enveloped viruses, while the observed changes in deceased COVID-19 patients may indicate its deviation.
