How health care professionals confront and solve ethical dilemmas – a tale of two countries: Slovenia and Croatia

AimTo assess the differences in the way how Slovenian and Croatian health care professionals (HCPs) confront ethical dilemmas and perceive the role of hospital ethics committees (HECs).MethodsThis cross-sectional, survey-based study involved HCPs from three Slovenian and five Croatian university medical centers (UMC). The final sample sizes were 308 (244 or 79.2% women) for Slovenia and 485 (398 or 82.1% women) for Croatia.ResultsCompared with Croatian physicians, Slovenian physicians reported a higher share of ethical dilemmas regarding waiting periods for diagnostics or treatment, suboptimal working conditions due to interpersonal relationships in the ward, and end-of-life treatment withdrawal, and a lower share regarding access to palliative care and patient information protection. Compared with Croatian nurses, Slovenian nurses reported a lower share of ethical dilemmas regarding the distribution of limited resources, recognizing the patient’s best interests, and access to palliative care. Compared with Croatian other HCPs, Slovenian other HCPs reported a lower burden of ethical dilemmas regarding waiting periods for diagnostics or treatment, distribution of limited resources, and access to palliative care. When encountering an ethical dilemma, all HCPs in both countries would first consult their colleagues. Slovenian and Croatian HCPs recognized the importance of the HECs to a similar extent, but viewed their role differently.ConclusionCroatian and Slovenian HCPs are confronted with different ethical dilemmas and perceive the role of HECs differently.

An ethical dilemma arises when we are confronted with a situation with two morally justifiable solutions, none of which is entirely satisfactory (1). In the course of their daily work, health care professionals (HCPs) encounter a broad range of ethical dilemmas (2-4), which often result in a moral distress for HCPs (5,6). A critical requirement for a successful response to an ethical dilemma is a strong foundation in medical professionalism cultivated during medical training and consolidated during professional work experience and career development (7-9).Slovenia and Croatia, previously the westernmost republics of the former Yugoslavia and now European Union members, share the same historical, geopolitical, economic, and religious background. A recent survey in the largest Slovenian tertiary hospital, the University Medical Center Ljubljana, found that the most important contexts that give rise to ethical dilemmas among HCPs were waiting periods for diagnostics and treatment, suboptimal working conditions due to poor interpersonal relationships, and preserving patients'' dignity, while the least important contexts were biomedical research, organ transplantation, and vaccine hesitancy (10). A study at the University Medical Center Rijeka found similar main ethical dilemmas in Croatian nurses and physicians, which included limiting life-sustaining therapy, euthanasia, and physician-assisted suicide (11).Except these two studies, little to nothing is known about the ethical dilemmas of HCPs in Slovenia and Croatia. In response to this limited evidence, we conducted a prospective survey with a primary objective to assess the differences in the share of ethical dilemmas among different categories of HCPs (physicians, nurses, and other HCPs) in Slovenian and Croatian tertiary hospitals (university medical centers, UMCs). The UMCs were purposively selected because in this kind of hospitals, one encounters complicated cases usually referred from other health care institutions for complex diagnostic and therapeutic procedures, which can often raise ethical issues. The secondary objectives of our survey were to study differences in the opinion on the existence of standard procedures when HCPs are facing an ethical dilemma; to determine whom HCPs consult when facing an ethical dilemma; and to identify the opinion on the importance of hospital ethics committees (HECs) and their role in Slovenia and Croatia.     

Quality of life predictors in patients with chronic inflammatory demyelinating polyradiculoneuropathy

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a chronic disease which can lead to many functional impairments, and like most other chronic disorders it might significantly affect quality of life (QoL). Information about QoL in patients with CIDP from developing countries is still lacking. We, therefore, sought to complete these data mosaic by investigating QoL in patients with CIDP from Serbia and surrounding countries. Our study comprised 106 patients diagnosed with CIDP. QoL was investigated using the Serbian version of the SF-36 questionnaire. The Medical Research Council 0–5 point scale, INCAT motor and sensory scores, Krupp’s Fatigue Severity Scale, and Beck Depression Inventory were also used. Factors that significantly correlated with SF-36 total score in univariate analysis were included in the multiple linear regression analysis. Physical domains of the SF-36 were more affected than mental, and the overall score was 56.6 ± 25.4. Significant predictors of worse SF-36 score in our patients with CIDP were severe fatigue (β = ? 0.331, p < 0.01), higher INCAT motor score (β = ? 0.301, p < 0.01), depression (β = ? 0.281, p < 0.01), being unemployed/retired (β = ? 0.188, p < 0.05), and shorter duration of CIDP (β = + 0.133, p < 0.01). QoL was reduced in CIDP patients, especially in physical domains. Patients with presence of fatigue and depression, with more severe motor disability, unemployed/retired ones, and those with shorter duration of the disease need special attention of clinicians since they could be at higher risk to have worse QoL.     

Clinical and epidemiological features of Guillain‐Barré syndrome in the Western Balkans

The aim of this study was to define features of Guillain‐Barré syndrome in a large cohort of patients from three Western Balkans countries. Data from adult Guillain‐Barré syndrome (GBS) cases from 2009 to 2013 were retrospectively obtained from all tertiary health care centers. During the 5‐year period, 327 new cases of GBS were identified with a male to female ratio of 1.7 : 1. The most common GBS variants were demyelinating (65%) and axonal (12%). At nadir 45% of patients were chair‐bound, confined to bed, or required assisted ventilation, while 5% died. The crude incidence of GBS in Serbia and Montenegro was 0.93 per 100,000 population, and age‐adjusted incidence according to the world standard population was 0.86 per 100,000. Incidence was particularly high in 50‐ to 80‐year‐old men. Statistically significant seasonal variations of GBS were not observed. This study of patients with GBS in the Western Balkans allows us to prepare the health system better and to improve the management of patients. This study also opens opportunities for international collaboration and for taking part in the multinational studies on GBS.     

The complex enterprise of modelling prenatal exposure to cigarettes: what is ‘enough’?

While there is a burgeoning body of research linking smoking during pregnancy to problem behaviour in offspring, a major criticism of this work has been the crude measurement of exposure in these studies (e.g. retrospective, self-reported only) that could lead to biased estimates. To address this issue, we used a pregnancy cohort with repeated prospective measures of exposure as well as biological assays to generate estimates of exposure patterns using a range of modelling techniques. In this paper we report on the analytical approaches we have developed, including patterns of exposure over time and best-estimate approaches that combine self-report and cotinine measures, and compare their predictive value in relation to different dimensions of fetal growth as a first step towards examining the utility of greater precision of exposure measurement.
Surprisingly, in this sample the more complex assessments of exposure, including biological measures, generally did not perform better than simple indicators of exposure based on repeated self-report measures, with one exception: a combined self-report cotinine 'best estimate' of third trimester exposure was uniquely associated with lower brain : body ratio. Further study is needed using more sophisticated cotinine assays and testing prediction of a range of outcomes to ascertain whether these findings represent true differences or are specific to the sample, methods and outcomes used. Such research will inform the development of guidelines for adequate exposure characterisation in developmental studies.     

Physiological correlates of burnout among women

OBJECTIVES: The purpose of this study was to investigate the immune, endocrine, and metabolic correlates of burnout among women. METHODS: Forty-three participants with high and 20 participants with low scores for the Shirom-Melamed Burnout Questionnaire were compared in terms of subjective symptoms, job strain, social support, plasma levels of prolactin, tumor necrosis factor alpha (TNF-alpha), transforming growth factor beta (TGF-beta), C-reactive protein (CRP), neopterin, serum levels of dehydroepiandrosterone sulphate (DHEAs), progesterone, estradiol, cortisol, and glycated hemoglobin (HbA1C) in whole blood. RESULTS: Besides reporting more job strain, less social support at work, and higher levels of anxiety, depression, vital exhaustion (VE), and sleep impairments, participants with high burnout manifested higher levels of TNF-alpha and HbA1C, independent of confounders including depression. CONCLUSIONS: Among women, burnout seems to involve enhanced inflammatory responses and oxidative stress.     

Lentivirus lytic peptide 1 perturbs both outer and inner membranes of Serratia marcescens

Bis-lentivirus lytic protein 1 (Bis-LLP1) and polymyxin B exhibited similar killing activities against Serratia marcescens. By electron microscopy, bis-LLP1 interacted with the outer and cytoplasmic bacterial membranes, while polymyxin B affected only the outer membrane. The results of standard biochemical probes supported the findings of the electron microscopy studies, suggesting that these antimicrobial peptides have different mechanisms of action.     

Tuberculous orchiepididymitis diagnosed by nucleic acid amplification test: A case report

Symptoms of tuberculous orchiepididymitis in a 39-year-old male started with swelling of left scrotum, followed by fistula formation with suppurative discharge. There was no any improvement produced by antibiotics. Surgical extirpation of inflammatory destroyed testicle and epidydimis was performed. Presence of tubercle bacilli was not shown by bacteriological analysis of testicle tissue. Tuberculous etiology was suggested after histopathological examination of testis and epididymis. Exudate from surgical wound was examined on presence of Mycobacterium tuberculosis DNA. Etiology of orchiepididymitis was proved by positive assay and inflammatory process was completely cured by antituberculotics therapy. By this report it was clearly shown that sometimes only molecular methods could confirm etiology of inflammatory process.     

Signal transduction pathways used by EGF to stimulate protein secretion in rat lacrimal gland

PURPOSE: To determine the effects of epidermal growth factor (EGF) on lacrimal gland secretion of proteins and characterize its signal-transducing components. METHODS: Both exorbital lacrimal glands were removed from male Sprague-Dawley rats. Dispersed acini were isolated by collagenase digestion in Krebs-Ringer bicarbonate (KRB) buffer at 37 degrees C. Acini were incubated with EGF (10(-7) M), the cholinergic agonist carbachol (10(-4) M), or the alpha(1)-adrenergic agonist phenylephrine (10(-4) M), and peroxidase secretion was measured by a fluorescence assay. To measure intracellular calcium ([Ca(2+)](i)), acini were incubated in fura-2 tetra-acetoxymethyl ester for 60 minutes at 22 degrees C, and fluorescence was measured at 340 and 380 nm with an emission wavelength of 505 nm. Extracellular Ca(2+) was chelated with KRB-BSA without CaCl(2) and with 2 mM EGTA before measurement of peroxidase secretion. Protein kinase C (PKC) was downregulated by incubating acini overnight, with or without the phorbol ester, phorbol 12-myristate 13-acetate (PMA; 10(-6) M), and peroxidase secretion was measured. RESULTS: EGF-stimulated peroxidase secretion in a concentration-dependent manner with a significant increase at 10(-7) M. EGF-stimulated secretion was inhibited by the EGF receptor (EGFR) inhibitor AG1478, but not by the phosphoinositide-3 kinase inhibitor LY292004 or the mitogen-activated kinase kinase (MEK) inhibitor U0126. EGF increased [Ca(2+)](i), whereas chelation of extracellular Ca(2+) inhibited EGF-induced peroxidase secretion by 90%. Downregulation of PKC also inhibited EGF-stimulated peroxidase secretion. CONCLUSIONS: EGF stimulates lacrimal gland secretion of protein by activating the EGFR to increase [Ca(2+)](i) and activate PKC.
