Review

[The use of medicinal plants in the preven­tion and treatment of Covid-19 started soon after the pandemic began. In some countries (e.g. China), the use of medicinal plants for this purpose was an officially declared goal. The plants used in therapy were selected on the basis of in silico studies, preclinical data or extrapolation of folk medicinal experience. In other parts of the world, the majority of medicinal plants are used by Covid patients outside of formal medicine, typically as food supplements. In this article, we review randomised controlled clinical trials of herbal preparations, indtoducing the potential place of herbal preparations in the therapy of Covid-19. A total of 17 trials were identified, most of which studied the effect on disease symptoms. Although most of the products tested were shown to be effective in at least one endpoint, the quality of the studies (mostly open-label, using non-standardised formulations) does not allow positive conclusions on efficacy. ]

[Attitudes towards end-of-life decisions among neonatology intensive care workers – Legal aspects behind decisions ]

FEITH Helga Judit, SALLAI Eszter Zsófia, SOÓSNÉ Kiss Zsuzsanna, GÉZSI András, GRADVOHL Edina, KOVÁCS Aranka, BERBIK István, SZABÓ Miklós

[Minors’ end-of-life dilemmas are among the most difficult decisions. Premature infants’ chance of survival has greatly improved thanks to the development of technology. Under-age children’s quality of life, as an aspect, does not appear in the effective Hungarian legislation. The aim of our study is to survey the change in NICU (neonatology intensive care unit) workers’ opinions/attitudes after a 20-year-period about restrictions in severely impaired new-borns’ intensive cares. Quantitative, complete sociological surveys in the Hungarian NICUs using self-administered, anonymous questionnaires (n = 728). Cross-Tabulation analysis and Pearson chi-squared test have been used for the data evaluation. In both studies, the majority of participants agreed that if the condition is fatal, it may be appropriate to limit the intensive care. Acceptance of treatment withdrawal has increased, but active euthanasia is still not accepted. Most healthcare workers are unsatisfied with the current legal order and there is a need for change, especially in cases of fatal and poor prognosis. Despite the fact that the effective Hungarian health care regulation does not allow withdrawal of treatment even in severe conditions, a significant number of those working at Hungarian NICUs would consider it as acceptable in some cases, moreover the share of acceptance has in­creased in the last two decades. Comparing the results with the current regulations, it can be suggested that it is necessary to increase the sensitivity of the legislators and to change the related legislation.]

[Dual incretin therapy – a novel approach in the antidiabetic therapy of type 2 diabetes ]

WINKLER Gábor, KIS János Tibor

[The introduction of incretin-based blood glucose lowering drugs, the dipeptidyl peptidase inhibitors, and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have opened up new perspectives in the antidiabetic treatment of type 2 diabetes. Beneficial properties of these drugs have directed the attention to study further enterohormones with potentially favourable effects on carbohydrate metabolism. Since the point of attack of these hormones is partly different partly identical, based on theoretical considerations, activating simultaneously their receptors in terms of glycemic control may result in synergistic and additive effects. This study reviews the concept of lowering the blood sugar level in type 2 diabetes based on multiagonistic receptor stimulation further the potential benefits of co-stimulating GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptors. It also briefly discusses the first data on tirzepatide as the first representative of dual receptor agonists accepted for clinical use by the FDA.]

[Modern approach and advanced treatment of obesity ]

SIMONYI Gábor, BEDROS J. Róbert, WITTMANN István

[Obesity is a recurrent, progressive chronic disease associated with body fat accumula­tion the body. Due to the nature of the dis­ease, its treatment and care is a life-long program. Elements of therapy: lifestyle modification (diet and exercise), psychological treatment, medication and if necessary, surgery. The Hungarian Society of Obesity and Exercise, recommends a low-carbohydrate and high-protein diet in the first half year of the weight loss program. During physical activity, dynamic, aerobic forms of movement (e.g. walking, jogging, swimming, cycling, etc.) are preferred. The options of drug treatment in Hungary are orlistat, naltrexone/bupropion fixed dose combination and liraglutide sc (3.0 mg) and bariatric surgery, which all can contribute successfully to the weight loss program.]

[In a three-part article series, we present (1) the clinical protocol used by the Early Childhood Eating and Sleep Disorders Outpatient Clinic of the Heim Pál National Pediatric Institute; (2) the follow-up monitoring methodology of treatment efficacy; and (3) the first results obtained by this moni­toring program in a three-part ar­ticle. The Clinic with in-patient background was the first in the Hungarian health care system to provide organized care by interdisciplinary methods for families of infants and young children struggling with early child­hood emotional and behavioural regulation problems. The present first article concerns the clinical protocol of our facility based on the international literature and our own prior experiences. In the literature review, we emphasize especially the early childhood range of care for eating and sleep disorders. Thus, we justify the rationale of structure and activities of our Outpatient Clinic launched in 2017 by a brief summary of the international literature. Our aim is to inspire further health care providers to set up similar interdisciplinary services by a detailed description of our facility. ]

[To be a “good enough” physician – The identification and acceptance of shame]

KELEMEN Gábor

[For two and a half millennia, the subject of shame, either in a toxic form that results in the masking of errors or in an adaptive form that may promote patient safety, has been almost missing from the narrative of medicine. The author traces the path of medical problematization of shame, mainly in the light of the work of those Hungarian psychoanalytic doctors who have played a role in this process. In the light of the concept of a “good enough” doctor, he examines the negative consequences of perfec­tionism for excellence. ]

[Correlations Between Burnout and Socio-demographic and Workplace Related Factors Among Health-care Workers During The Covid-19 Pandemics]

NÉMETH Anikó, IRINYI Tamás

[The present study aimed to assess the level of burn-out among health-care workers in 2020 and its correlations with socio-demographic and workplace related factors. The cross-sectional study was conducted by the means of a self-constructed online survey in the beginning of 2021. The responses of 1965 people were analysed with the help of SPSS 23.0. Descriptive statistics, chi-square and Kruskal-Wallis probes were run (p<0.05). Severe burnout was present in 46.7% of the responders. Age, marital status, type of health-care provided and years spent in the health-care system didn’t show any correlation with burnout. Unsure vision, opinion about salary raise and uncertainty at the workplace influenced the level of burnout significantly (p<0.000). The mental health of health-care workers is in continuous decline, in which the COVID-19 pandemic might play a big role. People with worse mental health feel more uncertain regarding their future and job; this might make providing health-care more and more difficult.]

Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been rapidly developed to prevent coronavirus disease 2019 (COVID-19) pandemic. There is increasing safety concerns regarding COVID-19 vaccines. We report a 78-year old woman who was presented with tetraparesis, paresthesias of bilateral upper extremities, and urinary retention of one-day duration. Three weeks before these symptoms, she was vaccinated with CoronaVAC vaccine (Sinovac Life Sciences, China). Spine magnetic resonance imaging showed longitudinally extensive transverse myelitis (TM) from the C1 to the T3 spinal cord segment. An extensive diagnostic workup was performed to exclude other possible causes of TM. We suggest that longitudinally extensive TM may be associated with COVID-19 vaccination in this case. To the best of our knowledge, this is the first report of longitudinally extensive TM developing after CoronaVac vaccination. Clinicians should be aware of neurological symptoms after vaccination of COVID-19.

The effect of starting a meal with salt and date palm on taste impairment caused by COVID-19

ALTUN Yasar , BULBULOGLU Semra

This study was conducted to examine the effect of starting a meal with salt and date palm on the sense of taste in COVID-19 patients. This study was conducted using a randomized controlled method. Patient and disease information forms and Visual Analog Scale were used for data collection. Salt and date palm were used to stimulate the sense of taste in two different experimental groups. No procedure was made in the control group except for the practice of the clinic. The results were analyzed using SPSS version 25. The mean ages of all groups were between 43.42 ± 8.60 and 47.22 ± 12.04 years. Fever, sore throat, dry mouth, cough, muscle weakness, and similar symptoms were present in all groups. Significant improvements were found in patients with hypoageusia and ageusia after date palm and salt application (p<0.01). For taste impairment caused by COVID-19, consumption of date palm and tasting very little salt for therapeutic purposes may help to alleviate taste impairment. Based on the data obtained from this study, the pathophysiology of the effects of date palm and salt on taste complications should be investigated.

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.
