[The COVID-19 pandemic caused by SARS-CoV-2 virus while emerging suddenly and spreading throughout the globe challenged seriously also the modern medicine. Diag­nostic methods recognising viral infections of the upper airways developed essentially in the last 20 years, and it was specifically progressing during the SARS and MERS epidemics thus facilitating the recognition and identifica­tion of infections by influenza, RS- and adenoviruses as well. Nevertheless the present novel coronavirus (SARS-CoV-2) also de­mon­strated that the relatively simple procedures of naso- and oropharyngeal sampling are fallible too. Thus they may have a relatively high risk of false-negative outcomes. However the correct sampling prior the RT-PCR tests provides reliable diagnosis by high sensitivity and specificity. Thus improving the quality of sampling and avoiding failures by correct training and education of the personnel make more reliable the detection of viral infection or indicate recovery after the infection. Finally, this is a key issue while overcoming the present pan­demic.]

[Avoiding unlimited energy drink consumption is a matter of our heart]

DOJCSÁKNÉ Kiss-Tóth Éva

[Energy drinks have been gaining unbroken popularity, especially among youngsters and children since they were introduced to the market. Manufacturers promise to improve performance and stamina with consuming the products, classified as non-alcoholic soft drinks. In addition to the vitamins and plant extracts, they contain a significant amount of caffeine and other stimulants (taurine, guarana). Among the active ingredients, caffeine has an outstanding effect and thereby a danger, since its overconsumption – in addition to milder he­mo­dynamic changes – can cause severe cardio­vascular consequences, cardiac arrhythmias, ion channel diseases, increased blood coagulation, myocardial infarction or reduced cerebral blood flow in susceptible consumers. Many case studies have also reported serious cardiovascular attacks among young chronic energy drink consumers. Health impairments of excessive and long-term consumption of energy drinks have been studied increasingly, however there is limited and contradictory evidence on the safety of consumption and the effectiveness of performance enhancement. ]

[Treatment of hypercholesterolemia in the elderly]

BARNA István

[The percentage of population aged ≥65 years is mounting worldwide, among them those over 75 years is also growing. Athe­ro­scle­rosis is one of the most important and common disorder in the elderly responsible primarily for premature death and cognitive declining and impaired quality of life. Adequate lipid lowering therapy can decrease the risk of cardiovascular events – the main cause behind mortality – can extend life expectancy and improve the quality of life of patients. Effect of dietary treatment on cardiovascular risk reduction is as beneficial as in the younger populations. Regular physical activity reduces the risk of cardiovascular and overall mortality by 26% in males and 20% in females aged ≥65 years. If the medical history is negative for vascu­lar disorders, statin administration as a primary prevention is indicated for patients 65>years. In the population aged 75≥years individual benefit/risk assessment is needed before statin administration. Larger risk reduction can be achieved between 65-75 years than in subjects over 75 years. Concerning secondary prevention, statin treatment is of pre-eminent significance, and its administration is evidence-based in the elderly. For achieving the lipid goals, combined therapy with statin and ezetimibe is recommended in the primary as well as secondary cardiovascular prevention. ]

[Sarcopenia – muscle loss – pathomechanism, clinical presentation and metabolic comorbidities]

VERECKEI Edit, HODINKA László

[Sarcopenia, or the age-related involution of muscle strength and muscle mass, is a serious public health concern, due to the growing number of elderly population caused by nowadays demographic changes i.e. prolonged life expectancy. By ageing, the muscle tissue is shrinking gradually, leading to the loss of muscle strength and masses. This condition is called sarcopenia. Sar­co­penia is the simultaneous decrease of muscle mass, muscle strength and functional independence. In parallel the physical performance deteriorates (weakness, slowness and poor physical balancing). Fatigue, el­derly behaviour and weight loss are the consequences of these accumulating deficits, which associate with cognitive decline and result in increasing social isolation. The primary form of sarcopenia is the decrease of the energy production of muscle cells and then the death of muscle cells. Se­con­dary, endocrine dysfunctions, diseases of the nervous system, decreased physical activity, malnutrition or malabsorption, chronic infection accelerate the process and aggravate the patient’s condition. Complex genetic, biochemical and endocrine mechanisms take part in the development of sarcopenia. This involution is due to the impaired balance of restoring and depleting processes of muscles. A questionnaire and algorithm have been developed to recognize, screen and diagnose the risks of sarcopenic condition; these separate the sarcopenic and non-sarcopenic patients with specific cut-off values. Sar­co­penia can be diagnosed based on walking speed, decreased handgrip strength and measured or calculated muscle mass in persons over 65. Sarcopenia can be considered as a phenomenon of “physiological” aging, however, it becomes a disease when diagnostic cut-offs are exceeded and the patient experiences functional disability and declining quality of life. Prevention and treatment of sarcopenia and reducing the risk of falling are based on regular active resistance and coordination exercises. Options for pharmaceutical treatments are limited since despite of identified molecular targets there are no convincingly effective innovative therapy on the horizon. Nevertheless, there are some weak evidence for efficacy of the application of amino acids stimulating muscle cell differentiation, such as leucine or the analogue of beta-hydoxy-methylbutyrate beside exercise therapy.]

[Suicide endangering elderly people: risk factors, prevention and care]

BARACZKA Krisztina

[According to the data of the Hungarian Central Statistical Office (HCSO), the Hungarian citizens aged over 65 represented in 2001 11.8%, 2011 13.2% and 2019 19.3% of the total population. Providing services for aging (>60 years), aged (>75 years), very old (>90 years) and Matusalem (>100 years) individuals burdens heavily the health system and the socio-economic sector. Maintaining these people’s physical and mental health and self-perceived well-being is a pre-eminently important task. According to the World Health Organization (WHO) statistics based on data providing countries, the number of suicides committed in the population aged 60-79 has risen approximately by 21% between 1987 and 2006. The suicide rate in Hungary has decreased steadily and significantly since 1980 (4809 in 1980, 1656 in 2018, i.e. a decrease of 66%). Thus since 2018, Hungary is not among the top three countries in Europe and the top 15 in the world. However, the number of completed suicides and suicide attempts remains high and shows rising tendency in the elderly. Preventing suicide, exploring the risk factors and caring patients after attempted suicide we need to analyse thoroughly and disseminate widely the results of the recent researches. In this study, we re­viewed international and domestic literature data to find answers primarily to prevention issues. ]

[Minority students in Hungarian medical training]

SZÉL Zsuzsanna

[General health of minority people is usually worse than that of their majority peers and they often expe rience discrimination in the healthcare system. According to international literature, physicians belonging to any minority group are more likely to care for other mi nority people, therefore they may play a key role in reducing healthcare inequities. Anonymous, online questionnaire was distributed to medical students of the four Hungarian universities with medical schools (response rate was 8.86%). In this paper, we analyze our collected data about perceived discrimination with descriptive statistical methods. Results of confirmative statistical analyses (statistical tests) were considered exploratory in nature. 29.6% of respondents self-identified as a member of any minority. 63.0% of minority students and 53.8% of women indicated that they realized discriminated or were harassed in the last 12 months, meanwhile, 37.8% of non-minority students and 31.9% of males have experienced discrimination. Dis­cri­mi­na­tion related to ethnic origin, sexual orientation and disability are regarded as the most widespread forms of discrimination according to our respondents. Students are most likely to say that there is no age related discrimination on the grounds of age – both being under 30 years old (12.0%) and being over 55 (8.6%). Being the member of any minority group seems to have no effect on student’s/ one’s opinion how widespread the forms of dis crimination are. Minority students are more comfortable to work with a member of another minority. However male students feel more uncomfortable to work with a member of sexual or gender minorities compared to female counterparts. Mi­no­rity students tend to be more critical to the universities’ efforts to enhance diversity. Minority students and females may play a key role in reducing discrimination in medical training and in the healthcare system and in providing high-quality care for individuals who belong to any minority. Although there are more females than males in medical training they still report higher occurrence of perceived discrimination. However, it is important to emphasize the low response rate in our study, which does not allow us to draw any general conclusions.]

The effect of sniffing Turkish coffee on olfactory disorders in COVID-19 patients: An experimental clinical study

BULBULOGLU Semra, ALTUN Yasar

The current study aimed to examine the effect of sniffing Turkish coffee on the sense of smell in COVID-19 patients. This study utilized the experiment-control method. Data were collected using a patient and disease information form and the Connecticut Chemosensory Clinical Research Center (CCCRC) Test. An experimental group of patients sniffed Turkish coffee, and the coffee’s effect on the patients’ sense of smell was examined. All data were analyzed using SPSS version 25 (IBM). Of the patients in the experimental group, 25% had moderate hyposmia, 58.3% had severe hyposmia, and 16.7% had anosmia prior to sniffing Turkish coffee. After sniffing the Turkish coffee, 13.3% of these patients regained their ability to smell normally, while 18.3% had mild hyposmia, 45% had moderate hyposmia, 6.7% had severe hyposmia, and 16.7% had anosmia. There was no difference in the control group between first and second measurement. COVID-19 patients who sniffed Turkish coffee intermittently regained some of their sense of smell for one hour. Turkish coffee is cheap, fragrant, widely available, and easy to access. Therefore, results of this study suggest that it may be recommended for treating olfactory disorder in COVID-19 patients.

[Covid-19 associated neurological disorders]

SZÔTS Mónika, PÉTERFI Anna, GERÖLY Júlia, NAGY Ferenc

[The clinical signs of SARS-CoV-2 infection has become more recognisable in recent times. In addition to common symptoms such as fever, cough, dyspnea, pneumonia and ageusia, less common complications can be identified, including many neurological manifestations. In this paper, we discuss three Covid-19 associated neurological disorders (Case 1: Covid-19 encephalitis, Case 2: Covid-19 organic headache, Case 3: SARS-CoV-2-infection and ischaemic stroke). We emphasize in our multiple case study that during the present pandemic, it is especially important for neurologists to be aware of the nervous system complications of the virus infection, thus saving unnecessary examinations and reducing the frequency of patients’ contact with health care personnel. ]

[Treatment options for enormous carotid thrombus as a complication of SARS-CoV-2 infection]

KONCZ Júlia, OROSZ Viktor, SULYOK Zoltán, ANDRÁS Emőke, KÁDÁR Balázs, OLÁH Csaba

[In SARS-CoV-2 positive patients with corresponding neurological symptoms the presence of carotid bifurcation macrothrombus should always be considered. Hypercoagulopathy caused by viral endotheliitis, systemic inflammation and cytokine storm play an important role in its development. Here we present two patients treated with different treatment strategies because of carotid bifurcation macrothrombus as a complication of SARS-CoV-2 infection. In both cases, the soft macrothrombus was eliminated and the patients’ neurological condition were improved. Intravenous thrombolysis, acute carotid stenting with embolic filter protection device and mechanical thrombectomy with aspiration are effective treatments.]

[Neurological aspects of the COVID-19 pandemic caused by the SARS-CoV-2 coronavirus]

BERECZKI Dániel, STANG Rita, BÖJTI Péter, KOVÁCS Tibor

[By the spring of 2020 the COVID-19 outbreak caused by the new SARS-CoV-2 coronavirus has become a pandemic, requiring fast and efficient reaction from societies and health care systems all over the world. Fever, coughing and dyspnea are considered the major signs of COVID-19. In addition to the involvement of the respiratory system, the infection may result in other symptoms and signs as well. Based on reports to date, neurological signs or symptoms appear in 30-50% of hospitalized COVID-19 patients, with higher incidence in those with more severe disease. Classical acute neurological syndromes have also been reported to associate with COVID-19. A drop in the volume of services for other acute diseases has been described in countries with healthcare systems focusing on COVID-19. During the COVID-19 epidemic it is also important to provide appropriate continuous care for those with chronic neurological disorders. It will be the task of the future to estimate the collateral damage caused by the COVID-19 epidemic on the outcome of other neurological disorders, and to screen for the possible late neurological complications of the SARS-CoV-2 coronavirus infection.]
