[ScreenGPT - The opportunities and limitations of artificial intelligence in primary, secondary and tertiary prevention]

Bevezetés: A prevenció és a szűrővizsgálatok manapság egyre népszerűbbek. A páciensek – tudatosabbá válásuknak köszönhetően – többet kutatnak az interneten egészségi állapotukkal kapcsolatosan, függetlenül attól, hogy az mennyire megbízható. A ChatGPT megjelenése forradalmasította az információszerzést, így elkezdték azt öndiagnózisra és egészségi állapotuk menedzselésére használni. Annak ellenére, hogy a mesterségesintelligencia-alapú szolgáltatások nem helyettesíthetik az egészségügyi szakemberekkel történő konzultációt, kiegészítő szerepet tölthetnek be a hagyományos szűrési eljárások során, így érdemes megvizsgálni a lehetőségeket és a korlátokat. Célkitűzés: Kutatásunk legfőbb célkitűzése az volt, hogy azonosítsuk azokat a területeket, ahol a ChatGPT képes bekapcsolódni a primer, szekunder és tercier prevenciós folyamatokba. Célunk volt továbbá megalkotni az olyan mesterségesintelligencia-alapú szolgáltatás koncepcióját, amely segítheti a pácienseket a prevenció különböző szintjein. Módszer: A prevenciós területen a ChatGPT által nyújtott lehetőségeket a rendszernek feltett specifikus kérdésekkel térképeztük fel. Ezen tapasztalatok alapján létrehoztunk egy webapplikációt, melynek elkészítéséhez a GPT-4 modell szolgált alapul. A válaszok helyességét strukturált pontos kérdésekkel igyekeztük javítani. A webapplikáció elkészítéséhez Python programozási nyelvet használtunk, az alkalmazást pedig a Streamlit keretrendszer felhőszolgáltatásán keresztül tettük elérhetővé és tesztelhetővé. Eredmények: A tesztek eredményei alapján több olyan prevenciós területet azonosítottunk, ahol a ChatGPT-t hatékonyan lehetne alkalmazni. Az eredmények alapján sikeresen létrehoztuk egy webapplikáció alapjait, amely a ScreenGPT nevet kapta. Következtetés: Megállapítottuk, hogy a ChatGPT a prevenció mindhárom szintjén képes hasznos válaszokat adni pontos kérdésekre. Válaszai jól tükrözik az emberi párbeszédet, ám a ChatGPT nem rendelkezik öntudattal, így fontos, hogy a felhasználók kritikusan értékeljék a válaszait. A ScreenGPT szolgáltatást e tapasztalatok alapján sikerült megalkotnunk, számos további vizsgálatra van azonban szükség, hogy megbizonyosodjunk a megbízhatóságáról.

[Care of dementia in the general practice]

Treating and caring for people with dementia is a complex task, which can be achieved through cooperation between primary and specialist healthcare, social care and specialist care services. General practitioners are key players in the prevention, screening, treatment and care of dementia. Our aim was to present the general practitioner's aspects of modern dementia care through different levels of prevention. Educating patients to lead a healthy lifestyle and optimising their cardiovascular status reduces the risk of developing dementia. Emphasis was placed on early screening and referral to a specialist, and the importance of timely, individualised therapy for modern care. General practitioner's care of patients with dementia includes monitoring the progression of the disease as well as co-morbidities so that the quality of life of both the patients and their family can be improved by reducing complications. Family doctors also have an important role to support family members who care for the patient. In addition to presenting the current possibilities in Hungary, we reviewed the international literature and national guidelines, which must be followed continuously to ensure quality patient care.

[Abdominal and cranial ultrasound screenings in our Neonatal Intensive Care Unit]

INTRODUCTION

Previously, all admitted neonates to our tertiary Neonatal Unit, University of Szeged, had a cranial and abdominal ultrasound performed as part of their care.

OBJECTIVE

To analyze the findings and to evaluate the effectiveness of the universal ultrasound screening.

METHOD

Results of cranial and abdominal ultrasound imaging performed in our Unit between 1st January 2014 and 31st December 2015 were analyzed retrospectively. Abnormalities found during the screening scans were studied further and assessed until discharge and during the first 2 years. All imagings were performed by a radiologist.

RESULTS

During the examined 2 years, 579 neonates were admitted (gestational age mean 34.2 weeks [23-41, SD ± 4.04]), abdominal ultrasound was performed in 562 (97%) and cranial ultrasound in 560 (97%) babies, on the 3.6th day of life at an average (0-18, SD ± 2.24). Of all abdominal ultrasound scans, 87% (n = 488) was carried out as screening, and the found abnormalities in 140 (29%) of the cases: renal pelvic dilatation (n = 67 [47.9%]), free abdominal fluid (n = 17 [12.1%]), echogenic kidneys (n = 13 [9.3%]), congenital abnormalities of the kidney and urinary tract (n = 9 [6.4%]), abnormalities of the liver, bile system, adrenal gland [n = 14 [10%]). The screening identified 4 (0.8%) neonates with renal abnormilaties requiring surgical correction. In regards of renal abnormalities, we observed male (p = 0.18) and left sided (p = 0.54) predominance. Screening cranial ultrasound was performed in 65% (n = 362) of all neonates, discovering 51 (14%) anomalies: plexus chorioideus cyst (n = 21 [41%]), plexus chorioideus hemorrhage (n = 9 [17.6%]), mild ventricular asymmetry (n = 8 [15.7%]), subependymal hemorrhage (n = 5 [9.8%]), abnormalities of the periventricular area (n = 4 [7.8%]), colpocephaly, hydrocephalus externus, echogenic meninx and thalamic nodule [n = 1-1 (1.9-1.9%)].

CONCLUSION

Abdominal ultrasound screening discovered renal abnormalities and umbilical line complications as clinically relevant findings. However, a small number of renal abnormalities identified by screening required surgical intervention. Further studies are needed to identify possible risk groups to develop more efficient screening strategy to decrease the number of screened babies for 1 relevant finding (number to screen). Cranial ultrasound screening did not identify any abnormalities that needed intervention. We can not recommend universal cranial ultrasound screening based on our results.

[Hungarian Aphasia Screening Test: a new rapid screening tool for detecting aphasia in stroke patients]

INTRODUCTION

Although aphasia screening tools are widely used internationally, in Hungarian, to date, there have been no aphasia screening tests with reported psychometric properties available.

OBJECTIVE

(1) To provide an overview of the international practice and the tools of post-stroke aphasia screening. (2) To present a recently developed aphasia screening test in Hungarian.

METHOD

The Hungarian Aphasia Screening Test comprises five tasks assessing speech comprehension and production, and takes 5-10 minutes to complete. The test is easy to score and needs little equipment, therefore it can be useful in any clinical setting that allows for quick test administration and diagnostics. Based on results of two studies, we evaluate the psychometric properties and the diagnostic accuracy of the test, and determine three impairment severity ranks (mild, moderate, severe aphasia) for the test. The severity ranks were defined based on results of 70 people with post-stroke aphasia (35 women; average age: 61.4 years; average postonset: 12.6 months).

RESULTS

The test has high diagnostic accuracy, a sensitivity of 92.5% and a specificity of 88.5%. It shows acceptable structural and concurrent (MR = 0.68) validity as well as good internal consistency (Mα = 0.74). The cut-off score for diagnosing aphasia is 17.

DISCUSSION

The test can differentiate stroke patients with and without aphasia. With the use of the test, patients' aphasia can be rated as mild (score 14-17), moderate (score 9-13), or severe (score 0-8). Our results suggest that it is a reliable and valid screening tool.

CONCLUSION

The test can detect the presence and quantify the severity of aphasia. We discuss the importance of aphasia screening in clinical settings and of the use of the Hungarian Aphasia Screening Test in the context of the international practices. Orv Hetil. 2022; 163(50): 2000-2008.

Model-based economic burden of diabetic retinopathy in Hungary

Összefoglaló. Bevezetés: A diabeteses retinopathia minden harmadik cukorbeteget érinti a világban, és a dolgozó korú lakosság körében a vakság vezető oka. Célkitűzés: Tanulmányunk célja a diabeteses retinopathia prevalenciaalapú költségterhének meghatározása 2018-ban a 18 évnél idősebb korú lakosság körében Magyarországon. Módszer: Standardizált 'rapid assessment of avoidable blindness' (RAAB) + diabeteses retinopathia modul alapú metodikán alapuló modellel analizáltuk a diabeteses retinopathia költségterhét. A diabeteses retinopathia okozta gazdasági terhet a Nemzeti Egészségbiztosítási Alapkezelő és a páciensek oldaláról felmerülő költségeket analizálva vizsgáltuk. A prevalenciaalapú diabeteses retinopathia költségmodellt a skót diabeteses retinopathia klasszifikációnak és a diabeteses retinopathia súlyossági stádiumának megfelelően állítottuk össze. Eredmények: A diabeteses retinopathia költségterhe 43,66 milliárd Ft volt 2018-ban. A két fő költségviselő az anti-VEGF-injekciók (28,91 milliárd Ft) és a vitrectomiák (8,09 milliárd Ft) voltak. Ez a két kezelési mód volt felelős a diabeteses retinopathiával kapcsolatban felmerülő összes költség 84,7%-áért. Az egy páciensre jutó átlagos költségteher 54 691 Ft volt hazánkban. Következtetés: A cukorbetegek szemészeti járó- és fekvőbeteg-ellátása alulfinanszírozott hazánkban. A proliferatív diabeteses retinopathia és a diabeteses maculaoedema növekvő társadalmi-gazdasági terhe miatt érdemes volna javítani a megelőzés, a szűrés és a korai kezelés jelenlegi helyzetén. Orv Hetil. 2021; 162(8): 298-305.

SUMMARY

INTRODUCTION

Diabetic retinopathy affects every third people with diabetes mellitus in the world and is the leading cause of blindness in adults of working age.

OBJECTIVE

The aim of this study was to analyse the economic burden associated with diabetic retinopathy in people aged 18 years and older in Hungary.

METHOD

Rapid assessment of avoidable blindness (RAAB) with the diabetic retinopathy module (DRM) based diabetic retinopathy cost model study was conducted in Hungary in 2018. Economic burden of diabetic retinopathy was analysed from the perspective of the National Health Insurance Fund system and the patients. Our prevalence-based diabetic retinopathy cost model was performed according to the Scottish diabetic retinopathy grading scale and based on the diabetic retinopathy severity stadium.

RESULTS

The total diabetic retinopathy-associated economic burden was 43.66 billion HUF in 2018. The two major cost drivers were anti-VEGF injections (28.91 billion HUF) and vitrectomies (8.09 billion HUF) in Hungary; they covered to 84.7% of the total cost among people with diabetes mellitus. The diabetic retinopathy-related cost per patient was 54 691 HUF in Hungary.

CONCLUSION

Outpatient and inpatient eye care of people with diabetes mellitus are underfinanced in Hungary. Due to the increasing socio-economic burden of proliferative diabetic retinopathy and diabetic macular oedema, it would be important to invest in proliferative diabetic retinopathy and macular oedema prevention, screening and early treatment.

Screening for multiresistant pathogens before cataract surgery

Összefoglaló. Bevezetés: A multirezisztens kórokozók által okozott fertőzések komoly gondot okoznak. Szemészeti szempontból az ebbe a körbe tartozó meticillinrezisztens Staphylococcus aureus (MRSA) baktérium bír kiemelkedő jelentőséggel. Célkitűzés: Multirezisztens kórokozók irányában cataractaműtét előtt álló betegektől mintavétel és adatelemzés. Módszer: 257, cataractaműtét előtt álló beteg esetében végeztünk multirezisztens kórokozók szűrésére vizsgálatot a conjunctivazsákból. A mikrobiológiai tenyésztés során multirezisztens kórokozóra pozitív eredményt adó betegek esetében a preoperatív kórtörténetet és az általános kísérő betegségeket feltártuk és elemeztük. Eredmények: A minták 17 beteg esetében multirezisztens kórokozóra pozitívak voltak. 11 esetben szisztémás rizikófaktorokat is találtunk. A pozitív betegeknél a műtétet csak a felszabadító mikrobiológiai eredmények birtokában végeztük el. A dekolonizált betegeknél ezt követően a szakmai protokoll normális antibiotikumprevencióját alkalmaztuk. A 257 beteg 6,6%-ában találtunk multirezisztenskórokozó- és 5%-ában MRSA-pozitivitást. Posztoperatív endophthalmitis nem fordult elő. Következtetés: A cataractaműtéteknél alkalmazott antibiotikus endophthalmitisprevenció multirezisztens kórokozóra pozitív betegeknél kevéssé hatékony lehet. Ezért javasolt a veszélyeztetett betegek multirezisztens kórokozókra történő szűrése és dekolonizációja. Orv Hetil. 2021; 162(3): 106-111.

SUMMARY

INTRODUCTION

Infections caused by multiresistant pathogens may have serious consequences. In ophthalmological practice, methicillin-resistant Staphylococcus aureus (MRSA) is the most important multiresistant pathogen.

OBJECTIVE

We took samples for multiresistant pathogens from patients assigned for cataract surgery.

METHOD

We carried out multiresistant pathogen screening from conjunctival sac in 257 patients, who were assigned for cataract surgery. Preoperative case history and concomitant systemic diseases were evaluated in patients, who turned out to be positive for multiresistant pathogens during the screening procedure.

RESULTS

The samples were positive for multiresistant pathogens in 17 patients. In the case history of 11 multiresistant pathogen positive patients, previous systemic risk factors could be explored. Multiresistant pathogen positive patients were operated only after the decolonisation. After the decolonisation, the normal antibiotic prevention was used before the surgery. Multiresistant pathogen positive was 6.6%, MRSA positive was 5% of the 257 patients. There were no cases of endophthalmitis in any of these patients.

CONCLUSION

Endophthalmitis prevention with antibiotics, according to the guidelines, may not be efficient in multiresistant pathogen positive patients. Therefore, it is advisable to screen multiresistant pathogens and decolonisation at risk patients before cataract surgery. Orv Hetil. 2021; 162(3): 106-111.

A summary of data of screening of the lower limb peripheral arterial diseases in the region of Northern Hungary

INTRODUCTION

The screening tool for diagnosing lower extremity arterial disease (LEAD) is the assessment of the ankle-brachial index (ABI). In patients at risk for LEAD, the purpose of screening is to avoid major adverse limb events, such as amputation. However, resting ABI can easily produce a false negative result.

AIM

In light of this, our goal was to test the usefulness of an easily performed, fast and cost-effective screening method and to determine the proportion of subjects without definitive diagnoses among patients screened in general practice (with special attention to groups having negative ABI with symptoms and patients with non-compressible arteries).

METHOD

680 patients were screened from the region of Northern Hungary. We used the Edinburgh Questionnaire, recorded medical histories, major risk factors, current complaints, and medication. Physical examinations were performed, including ABI testing.

RESULTS

34% complained about lower extremity claudication; 23% had abnormal ABI values; 14% of the patients within the normal ABI range had complaints of dysbasia; 12% were in the non-compressible artery group. The ABI-negative symptomatic group's risk factor profile showed a close similarity to the clear LEAD-positive and non-compressible artery groups.

CONCLUSION

The percentage of LEAD could be higher than the number of patients diagnosed by ABI screening. Nearly a quarter of the population fell into the non-compressible artery and ABI-negative symptomatic groups. When screening purposely for LEAD, these patients deserve special attention due to the insufficient selectivity and sensitivity of measurements. If there is a high clinical suspicion of LEAD in spite of normal ABI values, further assessment may be considered. Orv Hetil. 2020; 161(33): 1381-1389.

[Retrospective examination of the Hungarian breast and cervical cancer screening programmes according to mortality and morbidity data]

Introduction: The organized breast and cervical screening programs were implemented in the framework of public health program in Hungary in order to reduce breast cancer mortality by 30% and cervical cancer mortality by 60% in given age groups within 10 years by 2012. Aim: The aim of our study was to conduct a retrospective analysis of mortality and morbidity data and to evaluate the effectiveness of the implemented screening programs. Method: Descriptive statistical analysis was performed by age-standardized mortality and morbidity data between 1980 and 2015 with special regard to the period of 2002-2012. Results: Breast cancer mortality of women aged 45-64 reduced by 28.3%, the incidence reduced by 23.6% and the incidence of in situ carcinoma increased by 242% between 2002 and 2012. Cervical cancer mortality of women aged 25-64 years reduced by 25.5%, the incidence reduced by 21.2%, and the incidence of in situ carcinoma increased by 13.3% during 2002-2012. Conclusion: Although both breast cancer and cervical cancer mortality substantially decreased in Hungary, the decrease in cervical cancer did not reach the target value.

[Three decades of the hepatitis C virus from the discovery to the potential global elimination: the success of translational researches]

More than 25 years after the discovery of hepatitis C virus, the development of the direct acting antivirals can lead to the regional or long-term global elimination of the virus with over 90% efficacy. This is the success of basic and clinical translational research. Yet, some unsolved challanges remain, such as the great number of unidentified patients who are not aware of their condition, the limited access to the therapy due to the high prices of the drugs, and the treatment of resistance-associated variants. In addition, the lack of vaccine is also an obstacle. In 2016, the World Health Organization (WHO) developed the first global health sector strategy for the elimination of viral hepatitis by 2030. Its evidence-based guidelines are primarily targeted at the national hepatitis programme managers who are responsible for the national testing and treatment plans. According to these recommendations, it is of basic importance to perform focused risk-based testing in higher-risk populations and after diagnosis to start treatment as "cure as prevention", furthermore, to limit the risk of reinfection. We review the events of the HCV story from the discovery to these days, including virology, epidemiology, pathogenesis, diagnosis and therapy. Orv Hetil. 2018; 159(12): 455-465.

[Everyday suspicion: our life is delusional]

Suspicious thinking in given situations can be useful and helps the adaptation as events occurring in the world also corroborate this. Factors participating in the development of paranoia can be listed as psychodynamic (projection), salience attributional, neurobiological (dopamine), impaired perceptual (hearing loss), sociocultural (minority, pseudocommunity), self-esteem (worrying, depression, mania), and cognitive (jump-to-conclusion) mechanisms. Along the spectrum of thinking, from the mild to the severe, enhanced worrying, salience attribution, overvalued concepts, suspicion/mistrust, paranoid ideations, and crystallized delusions may occur with different contents. In recent years intensive research has been started to reveal the presence of subclinical paranoid thoughts in the general population. Applying various screening methods developed for this purpose (delusions inventories, psychometric tests, virtual reality laboratory) it has been found that suspicious/mistrustful ideations are fairly common in nonclinical samples and some of these are comparable to that seen in patient population. From the larger occurrence of milder forms to the smaller frequency of more severe delusional thoughts the whole hierarchical phenomenon can be described as a 'paranoia pyramid'. Based on this everyday paranoid thinking style lurking in people, it may well be that 'our life is delusional'. Orv. Hetil., 2016, 157(50), 1979-1988.

[Incidence of hepatocellular carcinoma and consequent lessons for its management in Northeastern Hungary]

INTRODUCTION

The increasing incidence and poor prognosis of hepatocellular carcinoma places huge burden on healthcare.

AIM

After reviewing literature on epidemiological trends, risk factors, diagnosis and management options for hepatocellular carcinoma, the authors investigated results of treatment and survival data of patients in Northeastern Hungary.

METHOD

In a retrospective study, the authors analyzed medical records of 187 patients with hepatocellular carcinoma (etiology, presence of cirrhosis, stage of the tumor, treatment and disease outcome).

RESULTS

Seventy-one patients (38%) had known cirrhosis at the diagnosis of hepatocellular carcinoma, while in 52 patients (28%) the presence of cirrhosis was established at the time of the diagnosis of hepatocellular carcinoma. Fifteen patients (8%) had no cirrhosis and in 49 patients (26%) no data were available regarding cirrhosis. Etiological factors were alcohol consumption (52%), viral hepatitis (41%) and metabolic syndrome (44%). In cases of metabolic syndrome, hepatocellular carcinoma frequently occurred without cirrhosis. In 83% of the cases, the tumor was discovered in an advanced stage. Median survival time was significantly associated with tumor stage (Barcelona A stage vs. B/C vs. D: 829 vs. 387 vs. 137 days, respectively p<0.001) but not with disease etiology (virus 282 days, metabolic syndrome 335 days and alcohol 423 days, p = 0.65).

CONCLUSIONS

High mortality of hepatocellular carcinoma was mainly attributed to the delayed diagnosis of the disease. Screening of patients with cirrhosis could only result in a partial improvement since in a great proportion cirrhosis was diagnosed simultaneously with the tumor. Screening of diabetic and obese patients by ultrasonography should be considered. Management of baseline liver disease is of importance in the care of hepatocellular carcinoma. Orv. Hetil., 2016, 157(45), 1793-1801.

[Non-alcoholic fatty liver disease and hepatocellular carcinoma - 2016]

In the past decade non-alcoholic liver disease became the most frequently diagnosed liver disease in developed countries. At the same time, the dramatic rise in the incidence of hepatocellular carcinoma is attributed to this common metabolic disorder, and mainly to its severe form, non-alcoholic steatohepatitis. The risk factors of these associated diseases are genetic predisposition, obesity and diabetes as well as chronic low grade necro-infammation, which often leads to liver fibrosis. Free fatty acids, cytokines, lipotoxicity, insulin resistance, microRNS dysregulation and alteration in intestinal microbiota play a pivotal role in the pathogenesis. Treatment of non-alcoholic fatty liver disease - weight reduction and physical exercise in obesity, metformin in diabetes, statins in dyslipidemia and, as a new option, obeticholic acid - may diminish the risk of the hepatocellular carcinoma related to this metabolic disease.

[Latest international guidelines for screening, prevention and treatment of familial breast cancer - implications for the relevant practice in Hungary]

INTRODUCTION

Screening, prevention and treatment of familial breast cancer require a multidisciplinary approach. New guidelines were published in the United Kingdom for the management of familial breast cancer.

AIM

The authors summarise these new guidelines and analyse the relevant practice in Hungary.

METHOD

Relevant guidelines of the National Institute for Health and Care Excellence and Familial Breast Cancer Report (NHS Scotland) are described.

RESULTS

New guidelines will increase the number of genetic tests as well as genetic counselling. An increase in the number of breast magnetic resonance imaging is expected, too. Chemoprevention can be offered for individuals with medium risk and above. Promising trials are underway with platinum based chemotherapy and polyADP-ribose polimerase inhibitors for the systemic treatment of familial breast cancer. The increase in the number of genetic tests, counselling, and breast magnetic resonance imaging may have a significant impact on health care budget.

CONCLUSIONS

These guidelines will change some aspects of the current management of familial breast cancer. Orv. Hetil., 2016, 157(28), 1117-1125.

[Frailty syndrome: an old new friend]

Frailty syndrome is defined as extreme stress vulnerability and decreased potential to adapt. The elderly and chronically ill patients are affected mostly. This condition increases the risk of adverse health outcomes as infections, falls, delirium, institutionalization, progression of comorbidities and mortality. The pathophysiological mechanism is a complex immune and neuroendocrine dysregulation. According to the phenotype model, frailty presents when three of the followings occur: weakness, exhaustion, slowness, weight loss and decreased activity, while cumulative model counts the number of health deficits. Aging, frailty, dementia and depression are independent clinical entities; they may present separately but may also potentiate each other. Hence most of the frailty scales assess the physical, mental and social dimensions as well. Mild or moderate frailty is potentially reversible with an individualised caring plan. Given short, easy-to-use screening tools, risk groups can be identified in the primary care and referred to a specialised team for further treatment. Here the authors summarise the literature of a re-discovered, current clinical phenomena, frailty syndrome, focusing on the practical issues in primary care.
