[What to expect of PTCA today?]

MAJOR László, MOLNÁR Ferenc, BERENTEY Ernő, KÉKES Ede

[This article is a review of the changing indications for percutaneous coronary angioplasty during the last decade. The role of revascularisation and especially of PTCA in the treatment of coronary heart disease is explained. Coronarography is the most important morphol gic diagnostic tool for coronary artery disease. The importance of the topic of this article is enhanced by the position of Hungary at the top of morbidity and mortality statistics, and by the infrequency of revascularisation procedures, especially PTCA. PTCA proved to be a real alternative to a surgical procedure in about half of the patients indicated for revascularisation. PTCA is less invasive, requires less time for recovery and is less expensive compared to bypass surgery. This article should draw attention of the family practitioner to the importance of this method. ]

[Myocardial contrast echocardiography]

TEMESVÁRI András, LENGYEL Mária, PAOLO Voci

[Symptoms of ischemic heart disease will occur when myocardial perfusion diminishes below a critical level. Coronarography will disclose the anatomic stenoses, but there is no direct correlation between the grade of stenosis and the change of myocardial perfusion. Myocardial contrast echocardiography is a new technique to analyze the myocardial perfusion. The contrast agent contains micro bubbles which have nearly the same dimensions as red blood cells. The microbubbles increase the „whiteness" of the perfused myocardium during the echocardiographic examinations. The change in „whiteness" of the myocardium correlates with myocardial perfusion. Intracoronary injections delineate the perfusion area of the coronary artery, and Thus the coronary flow reserve and the collateral flow area can be measured. The cardioplegia fluid distribution and the graft perfusion area are examined intraoperatively. Bedside myocardial perfusion studies will be possible through the transpulmonary passage of intravenously injected contrast agents. Myocardial contrast echocardiography can be applied both in the diagnosis and treatment of ischemic heart disease.]

[Randomised assessment of (the effect of) digoxin on inhibition of the angiotensin-converting enzyme study]

MATOS Lajos

[Circulatory failure worsened to the point of discontinuation in 23 patients in the diuretic + ACE inhibitor + placebo only group, compared to only four patients in the digoxin group (p<0.001). The relative odds of worsening circulatory failure with placebo compared with digoxin was 5.9. All measured parameters of functional capacity (maximal exercise capacity, submaximal exercise capacity, NYHA grade) worsened with digoxin withdrawal. Similarly, quality of life (p=0.04), ejection fraction (p=0.001), heart rate (p<0.001) and body weight (p<0.001) decreased with digoxin instead of placebo.]

[Investigation of uterine circulation by transvaginal color doppler in early pregnancy]

SZABÓ István, CSABAY László, NÉMET János, PAPP Zoltán

[The circulatory changes and the characteristics of blood flow in certain uterine vessels can be detected by transvaginal color Doppler in early pregnancy. The uterine circulation of 53 patients with normal intrauterine pregnancies at 4–14 weeks of gestation and 104 non pregnant patients were investigated. The main uterine artery, arcuated and spiral arteries were demonstrated by color Doppler in all patients in early pregnancy and characteristic flow velocity waveforms were obtained in 94% of the cases. The impedance to flow in the main uterine artery was significantly lower and the mean velocity was significantly higher in early pregnancy than in non pregnant patients. The indices of impedance to flow decreased with gestation in the uterine branches and there was a progressive fall in these indices from the uterine artery to the spiral arteries. Mean blood velocity in the uterine artery increased with gestation. The hemodynamical changes which are proportional to gestation age give an indirect evidence of the adequate maternal blood supply for the growing embryo.]

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

[What has Go to do with making clinical decisions? One of the greatest intellectual challenges of bedside medicine is making decisions under uncertainty. Besides the psychological traps of traditionally intuitive and heuristic medical decision making, lack of information, scarce resources and characteristics of doctor-patient relationship contribute equally to this uncertainty. Formal, mathematical model based analysis of decisions used widely in developing clinical guidelines and in health technology assessment provides a good tool in theoretical terms to avoid pitfalls of intuitive decision making. Nevertheless it can be hardly used in individual situations and most physicians dislike it as well. This method, however, has its own limitations, especially while tailoring individual decisions, under inclusion of potential lack of input data used for calculations, or its large imprecision, and the low capability of the current mathematical models to represent the full complexity and variability of processes in complex systems. Nevertheless, clinical decision support systems can be helpful in the individual decision making of physicians if they are well integrated in the health information systems, and do not break down the physicians’ autonomy of making decisions. Classical decision support systems are knowledge based and rely on system of rules and problem specific algorithms. They are utilized widely from health administration to image processing. The current information revolution created the so-called artificial intelligence by machine learning methods, i.e. machines can learn indeed. This new generation of artificial intelligence is not based on particular system of rules but on neuronal networks teaching themselves by huge databases and general learning algorithms. This type of artificial intelligence outperforms humans already in certain fields like chess, Go, or aerial combat. Its development is full of challenges and threats, while it presents a technological breakthrough, which cannot be stopped and will transform our world. Its development and application has already started also in the healthcare. Health professionals must participate in this development to steer it into the right direction. Lee Sedol, 18-times Go world champion retired three years after his historical defeat from AlphaGo artificial intelligence, be­cause “Even if I become the No. 1, there is an entity that cannot be defeated”. It is our great luck that we do not need to compete or defeat it, we must ensure instead that it would be safe and trustworthy, and in collaboration with humans this entity would make healthcare more effective and efficient. ]

Fluoxetine use is associated with improved survival of patients with COVID-19 pneumonia: A retrospective case-control study

NÉMETH Klára Zsófia, SZÛCS Anna , VITRAI József , JUHÁSZ Dóra , NÉMETH Pál János , HOLLÓ András

We aimed to investigate the association between fluoxetine use and the survival of hospitalised coronavirus disease (COVID-19) pneumonia patients. This retrospective case-control study used data extracted from the medical records of adult patients hospitalised with moderate or severe COVID-19 pneumonia at the Uzsoki Teaching Hospital of the Semmelweis University in Budapest, Hungary between 17 March and 22 April 2021. As a part of standard medical treatment, patients received anti-COVID-19 therapies as favipiravir, remdesivir, baricitinib or a combination of these drugs; and 110 of them received 20 mg fluoxetine capsules once daily as an adjuvant medication. Multivariable logistic regression was used to evaluate the association between fluoxetine use and mortality. For excluding a fluoxetine-selection bias potentially influencing our results, we compared baseline prognostic markers in the two groups treated versus not treated with fluoxetine. Out of the 269 participants, 205 (76.2%) survived and 64 (23.8%) died between days 2 and 28 after hospitalisation. Greater age (OR [95% CI] 1.08 [1.05–1.11], p<0.001), radiographic severity based on chest X-ray (OR [95% CI] 2.03 [1.27–3.25], p=0.003) and higher score of shortened National Early Warning Score (sNEWS) (OR [95% CI] 1.20 [1.01-1.43], p=0.04) were associated with higher mortality. Fluoxetine use was associated with an important (70%) decrease of mortality (OR [95% CI] 0.33 [0.16–0.68], p=0.002) compared to the non-fluoxetine group. Age, gender, LDH, CRP, and D-dimer levels, sNEWS, Chest X-ray score did not show statistical difference between the fluoxetine and non-fluoxetine groups supporting the reliability of our finding. Provisional to confirmation in randomised controlled studies, fluoxetine may be a potent treatment increasing the survival for COVID-19 pneumonia.

ALTAY Servet, GÜRDOGAN Muhammet, KAYA Caglar, KARDAS Fatih, ZEYBEY Utku, CAKIR Burcu, EBIK Mustafa, DEMIR Melik

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

[Comparative analysis of the full and shortened versions of the Oldenburg Burnout Inventory]

ÁDÁM Szilvia, DOMBRÁDI Viktor, MÉSZÁROS Veronika, BÁNYAI Gábor, NISTOR Anikó, BÍRÓ Klára

[Background – The two free-to-use versions of the Oldenburg Burnout Inventory (OLBI) have been increasingly utilised to assess the prevalence of burnout among human service workers. The OLBI has been developed to overcome some of the psychometric and conceptual limitations of the Maslach Burnout Inventory, the gold standard of burnout measures. There is a lack of data on the structural validity of the Mini Oldenburg Burnout Inventory and the Oldenburg Burnout Inventory in Hungary. Purpose – To assess the structural validity of the Hungarian versions of the Oldenburg Burnout Inventory and the Mini-Oldenburg Burnout Inventory. Methods – We enrolled 564 participants (196 healthcare workers, 104 nurses and 264 clinicians) in three cross-sectional surveys. In our analysis we assessed the construct validity of the instruments using confirmatory factor analysis and internal consistency using coefficient Cronbach’s α. Results – We confirmed the two-dimensional structure (exhaustion and disengagement) of the Mini-Oldenburg Inventory and a shortened version of the Oldenburg Burnout Inventory Internal consistency coefficient confirmed the reliability of the instruments. The burnout appeared more than a 50 percent of the participants in every subsample. The prevalence of exhaustion was above 54.5% in each of the subsamples and the proportion of disengaged clinicians was particularly high (92%). Conclusions – Our findings provide support for the construct validity and reliability of the Hungarian versions of the Mini-Oldenburg Burnout Inventory and a shortened version of the Oldenburg Burnout Inventory in the assessment of burnout among clinicians and nurses in Hungary.]
