RESUMO
OBJECTIVES: We aimed to (1) develop a novel instrument, suitable for the general population, capturing intentional non-adherence (iNAR), consisting of non-adherence to prescribed therapy, self-medication and avoidance of seeking medical treatment; (2) differentiate it from other forms of non-adherence, for example, smoking; and (3) relate iNAR to patient-related factors, such as sociodemographics, health status and endorsement of irrational beliefs (conspiratorial thinking and superstitions) and to healthcare-related beliefs and experiences ((mis)trust and negative experiences with the healthcare system, normalisation of patient passivity). DESIGN: То generate iNAR items, we employed a focus group with medical doctors, supplemented it with a literature search and invited a public health expert to refine it further. We examined the internal structure and predictors of iNAR in an observational study. SETTING: Data were collected online using snowball sampling and social networks. PARTICIPANTS: After excluding those who failed one or more out of three attention checks, the final sample size was n=583 adult Serbian citizens, 74.4% female, mean age 39.01 years (SD=12.10). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary, planned outcome is the iNAR Questionnaire, while smoking was used for comparison purposes. RESULTS: Factor analysis yielded a one-factor solution, and the final 12-item iNAR Questionnaire had satisfactory internal reliability (alpha=0.72). Health condition and healthcare-related variables accounted for 14% of the variance of iNAR behaviours, whereas sociodemographics and irrational beliefs did not additionally contribute. CONCLUSIONS: We constructed a brief yet comprehensive measure of iNAR behaviours and related them to health and sociodemographic variables and irrational beliefs. The findings suggest that public health interventions should attempt to improve patients' experiences with the system and build trust with their healthcare practitioners rather than aim at specific demographic groups or at correcting patients' unfounded beliefs. STUDY REGISTRATION: The design and confirmatory analyses plan were preregistered (https://osf.io/pnugm).

The inodilator levosimendan, in clinical use for over two decades, has been the subject of extensive clinical and experimental evaluation in various clinical settings beyond its principal indication in the management of acutely decompensated chronic heart failure. Critical care and emergency medicine applications for levosimendan have included postoperative settings, septic shock, and cardiogenic shock. As the experience in these areas continues to expand, an international task force of experts from 15 countries (Austria, Belgium, China, Croatia, Finland, France, Germany, Greece, Hungary, Italy, the Netherlands, Spain, Sweden, Switzerland, and the USA) reviewed and appraised the latest additions to the database of levosimendan use in critical care, considering all the clinical studies, meta-analyses, and guidelines published from September 2019 to November 2021. Overall, the authors of this opinion paper give levosimendan a "should be considered" recommendation in critical care and emergency medicine settings, with different levels of evidence in postoperative settings, septic shock, weaning from mechanical ventilation, weaning from veno-arterial extracorporeal membrane oxygenation, cardiogenic shock, and Takotsubo syndrome, in all cases when an inodilator is needed to restore acute severely reduced left or right ventricular ejection fraction and overall haemodynamic balance, and also in the presence of renal dysfunction/failure.
RESUMO
BACKGROUND: Tableware size may influence how much food and non-alcoholic drink is consumed. Preliminary evidence of the impact of glass size on purchasing of alcoholic drinks shows an increase in wine sales of almost 10% when the same portion of wine is served in a larger glass. The primary aim of the current study is to test if micro-drinking behaviours act as a mechanism that could underlie this effect, through an increase in drinking rate, sip duration and/or number of sips from a larger glass. METHODS: In a between-subjects experimental design, 166 young women were randomised to drink a 175 ml portion of wine from either a smaller (250 ml) or larger (370 ml) wine glass. Primary outcomes were three micro-drinking behaviours, assessed observationally using video recordings: drinking rate, sip number and sip duration. Other possible mechanisms examined were satisfaction with the perceived amount of wine served and pleasure of the drinking experience, assessed using self-report measures. RESULTS: Wine drunk from the larger, compared with the smaller glass, was consumed more slowly and with shorter sip duration, counter to the hypothesised direction of effect. No differences were observed in any of the other outcome measures. CONCLUSIONS: These findings provide no support for the hypothesised mechanisms by which serving wine in larger wine glasses increases consumption. While micro-drinking behaviours may still prove to be a mechanism explaining consumption from different glass sizes, cross-validation of these results in a more naturalistic setting is needed.

BACKGROUND/OBJECTIVE: Outcomes of kidney transplantation in older patients have not, however, been fully defined. The aims of this study were to analyze the number of new end-stage renal disease (ESRD) patients ≥65 years of age who were managed with kidney transplantation and their survival through the study period. In addition, we have analyzed post-transplantation outcomes in younger and older renal transplant recipients (RTRs). METHODS: We have analyzed the mean age of 505 RTRs transplanted between January 1990 and December 2013. Older people were defined as aging 65 years or older. Of 505 RTRs, there were 73 (14.5 %) patients who were ≥65 years of age. Therefore, in further analysis, patients were divided into two subgroups: younger recipients (younger than 65 years) and older recipients (aging 65 years or older). RESULTS: In the period from 1990 to 2001, patients who were 65 years of age and older were only sporadically treated with kidney transplantation in Croatia. Since 2002, the number of patients older than 65 years undergoing renal transplantation has been increasing. The older recipients were more likely to receive organs from older donors (52.6 ± 16.8 vs. 45.8 ± 13.2; p = 0.0001). There were no significant differences due to HLA mismatch between the two groups of analyzed patients. There was no difference in the rates of DGF between the older and younger recipients. Older recipients were less likely than younger recipients to have acute rejection crisis during the first-ear after transplantation (16.4 vs. 34.7 %; p = 0.03). There were no significant differences due to readmission rates in the first-year post-transplantation between the two groups. There was no significant difference due to graft function and 1-year graft and patient's survival between young and older recipients. Serum creatinine values at 1 year were higher in older recipients who received kidneys from elderly donor. CONCLUSION: Our experience supports the use of kidney transplantation in the population of older ESRD patients. We can increase patients and graft survivals in elderly individuals with careful pre-transplant evaluation and HLA matching. "Croatian senior program" that includes HLA matching represents a good approach for kidney transplantation in older ESRD patients.

OBJECTIVE: To report a case of fatal toxic epidermal necrolysis associated with carvedilol treatment. CASE SUMMARY: Two days after the initiation of carvedilol treatment, a 70-year old woman presented with skin eruptions in the form of maculous rash with blisters that rapidly progressed to epidermal necrolysis. Although the suspected drug was withdrawn, the reaction was extremely rapid in its development with fatal outcome. DISCUSSION: Carvedilol is not a drug commonly associated with TEN. To our knowledge there are no cases of carvedilol related TEN reported in the literature. CONCLUSION: Because of the close temporal relationship between the initiation of carvedilol treatment and the appearance of skin eruptions, and because carvedilol was the only new medication the patient had taken, the etiology of TEN was most likely a reaction to this drug. Physicians should be aware of this extremely rare but serious ADR.

Infections are leading causes of increased morbidity and mortality of severe traumatic brain-injured (STBI) patients. The mechanism underlying the susceptibility to the infections is still unexplained. The purpose of the study was to investigate changes in frequency of leucocytes subpopulations in peripheral blood of patients with STBI during the course of intensive care treatment. Twenty patients with STBI were included in the study. Healthy age- and sex- volunteers served as control. Peripheral blood samples were taken from these patients at day 1, 4 and 7, and peripheral blood mononuclear cells (PBMC) were isolated. The percentage of T, B lymphocyte, NK and NKT cells as well as monocytes was analysed by simultaneous detection of surface antigens using fluorochrome-conjugated monoclonal antibodies. The two major subsets of T lymphocytes (CD3(+)CD56(-)CD4(+) and CD3(+)CD56(-)CD8(+)) and NK cells (CD3(-)CD56(+dim) and CD3(-)CD56(+bright)) were also analysed by flow cytometry. Extracranial infections were presented in 55% patients with STBI. At day 4, the percentage of T lymphocytes with cytotoxic phenotype significantly diminished and their numbers restored at day 7. The frequency of NKT cells showed the identical time-dependent pattern, whereas the percentage of NK cells diminished on day 4 but did not restore after 7 days. The frequency of B lymphocytes did not change significantly during the time investigated, whereas the percentage of monocytes increased immediately after the injury and gradually diminished. The decrease in cells with cytotoxic phenotype might explain high incidence of susceptibility to infection of patients with STBI.

The aim of this investigation was to evaluate the role of ultrasonography in avoiding cranial misplacement of the tracheostomy tube and tracheal ring fractures during percutaneous dilatational tracheostomy (PDT). The tracheas of 26 consecutive ICU patients who had undergone PDT but who later died were removed en bloc at autopsy. The tracheas were opened along the membranous portion and the condition of tracheal rings and the site of tracheostomy macroscopically evaluated. The patients were divided in two groups: group A with 15 patients who underwent "blind" PDT and group B with 11 patients who underwent ultrasound-guided PDT. In five (33%) patients from group A, autopsy revealed that the tracheostomy tube was placed between the cricoid cartilage and the first tracheal ring (cranial misplacement) and in six (43%) patients a fracture of one tracheal ring was found. Cranial misplacement of the tracheostomy tube in patients from group B was not found (P < 0.05) and four (36%) patients had a broken tracheal ring (P = NS). The authors maintain that by using ultrasound-guided PDT cranial misplacement of the tracheostomy tube may be entirely avoided.

BACKGROUND & AIM: The gallbladder volume is a predictor of biliary stasis and the formation of biliary sludge. Biliary stasis and sludge have been recently recognized as the precursors of acute acalculous cholecystitis, as well as 'idiopathic' postoperative pancreatitis, rare but very serious complications after surgery. The aim of the study was to establish how early postoperative gastric supply of nutrients affects the gallbladder volume in patients after noncardiac and cardiac surgery. METHODS: In the two prospective, randomized studies 40 patients (study I-noncardiac surgery) treated at surgical ICU after major elective extrahepatobiliary and extragastrointestinal surgeries (7 thoracic, 19 vascular, 14 urological) and 40 patients (study II-cardiac surgery) treated at cardiosurgical ICU after CABG surgery were analyzed. In both studies the patients were divided into two groups: control group C (study I: 20 patients, age 45+/-18 yrs, male 65%; study II: 20 patients age 58+/-7 yrs, male 60%) and group E (group of early postoperative gastric supply of nutrients) (study I: 20 patients, age 52+/-17 yrs, male 50%; study II: 20 patients; age 59+/-8 yrs, male 65%). For the first 24 hours the patients in group C received only crystalloid solutions and the gallbladder volume was verified 24 hours after the surgery. In group E, postoperative gastric supply of nutrients began 18 hours after surgery (Osmolite, Ross; first 3 hours 30 ml/h and second 3 hours 50 ml/h; total 240 ml after 6 hours). In all patients sonographic measurement of gallbladder volume was performed immediately before surgery and 6 hours after the start of feeding (24 hours after surgery). The measurement was done with ultrasonographic scanner Hitachi 405 EUB (convex probe 3.5-5MHz) by the same specialist, and the volume was calculated using the ellipsoid method. RESULTS: The gallbladder volume measured by ultrasonography 24 hours after surgery in study I (noncardiac surgery) in group E amounted to 43+/-25 ml while in control group C it was significantly higher, i.e. 67+/-30 ml (P<0.05). In study II (cardiac surgery) in group E gallbladder volume amounted to 59+/-15 ml while in control group C it was also significantly higher, i.e. 71+/-11 ml (P<0.05). CONCLUSION: An early postoperative gastric supply of nutrients after both noncardiac and cardiac adult surgery diminishes the volume and probably stimulates the motility of the gallbladder, thus preventing biliary stasis and the formation of biliary sludge.

Patients with anterior cervical spine fixation (ACSF) after acute spinal cord injury often require tracheostomy for prolonged ventilatory support and upper respiratory tract clearance. The authors report two patients with ACSF who underwent a successful ultrasonographically guided percutaneous tracheostomy with dilatation forceps technique. Possible advantages of the ultrasonographically guided method with dilatation forceps in patients with ACSF are discussed.

In the last few years numerous reports from intensive care units confirm that a nonsurgical percutaneous tracheostomy has successfully replaced elective conventional (surgical) tracheostomy. The majority of authors point out the advantages over surgical technique such as: the speed of procedure, the possibility of doing it at bedside thus excluding transport and the need for operating theatre, less infections around stoma, minor cosmetic defects and finally, more economical price. The article describes three, according to pertinent literature most often utilized techniques, i.e. percutaneous dilatation tracheostomy with dilators, percutaneous dilatation tracheostomy with forceps, and translaryngeal tracheostomy. Main differences, advantages and defects of each method are presented. Contraindications and eventual complications are discussed, as well as the utility of supporting methods for safer placement of tracheostomy tubes, such as endoscopy and ultrasonography.
