[Our aim was to assess the prevalence of treated HT, the number of antihypertensive agents, especially ACE-inhibitors or ARBs among Covid-positive patients older than 18 years admitted to the Center for Disease Control of Department of Medicine of the University of Szeged. Data of 165 randomly selected patients (mean age 59.9±12.9 years, mean BMI 30.7±6.6 kg/m2) were analysed retrospectively. They were admitted between middle of February and end of April 2021. At the time of admission there were 103 (62.4% of all) HT patients (56 men, 47 women). The mean number of antihypertensive drugs were 1.6±1.6 pieces (max. 6) at the time of admission. 23 patients took more than 3 antihypertensives and 25 patients took exactly 3 drugs at home, and 20 patients had monotherapy. The antihypertensive therapy did not change in 74 cases, decreased in 6 cases and increased in 31 cases. In one case we could reduce therapy with 100%, monotherapy was finished, in the other 5 cases it was reduced by 50%. HT patients spent more days in hospital than non-HT patients (10.9±6.8 vs. 9.2±6.3). Spontaneous oxygen saturation (SatO2) was lower in HT patients compared to non-HTs at admission (89.6±9.7 vs. 92.6±4.8%) and patients who were on ARBs had the lowest SatO2 (87.5±8.5%, p=0.01 vs. non-HT). The total mortality rate was 8.7% in HT patients and it was just 1.6% in non-HT patients. 16.3% of HT patients with RAS-inhibitors and 13.0% without it required admission to the intensive care unit. The mortality rate was 10% of patients with RAS-inhibitors and 4.3% of them without it. This rate was 13% in patients with ARB and 8.8% with ACE-inhibitor. According to our results, HT may have higher risk for worse Covid-19 outcomes, including RAS-inhibitors also may have a higher risk.]

[Evaluation of affective temperaments in healthy controls and in different hypertension phenotypes]


[Affective temperaments (depressive, anxious, irritable, hyperthymic and cyclothymic) are stable parts of personality and describe the emotional reactivity for external stimuli. Their relation to psychopathological conditions is obvious, and increasing amount of data is available in cardiovascular disorders. The aim of this study was to evaluate affective temperaments in healthy subjects (Cont), in white-coat hypertensive (WhHT), in non-resistant (non-ResHT) and in resistant hypertensive (ResHT) patients. In this cross-sectional study, 363 patients were included: 82 Cont, 44 WhHT, 200 non-ResHT and 37 ResHT. The patients completed the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A). In ResHT cyclothymic affective temperament points (4 [2.25–8]) were higher (p<0.05) compared with Cont (2 [0–5]) and with non-ResHT (3 [1–5]). Cyclothymic temperament points of WhHT (4 [2–7]) were also higher compared with Cont. ResHT was independently associated with cyclothymic scale equal or above 6 (Beta=2.59 [95% CI: 1.16–5.77]), irritable scale equal or above 7 (Beta=3.17 [95% CI: 1.3–7.69]) and anxious scale equal or above 9 (Beta=2.57 [95% CI: 1.08–6.13]) points. WhHT was also independently associated with cyclothymic scale equal or above 6 points (Beta= 2.378 [95% CI: 1.178–4.802]). In conclusions, white-coat and resistant hypertensive patients have specific affective temperament patterns, and their evaluation can help to understand the psychopathological background of these conditions.]

[Administering single pill fixed combinations twice a day in the antihypertensive therapy]


[Optimizing the antihypertensive therapy usually does not mean simplifying the therapy. Most current antihypertensive agents have a 24-hour effect according to the prescribing information, but are not able to provide adequate blood pressure control in many patients. Among treated HT patients, a higher proportion of non-dippers occur in those who take all their antihypertensives at the same time in the morning. The recent evidence suggests that better blood pressure lowering results can be achieved when ACEis or ARBs are administered in the evening and not in the morning. There is hardly any data and practically no evidence that single pill fixed combinations should be administered twice daily, either in the same form in the same or in different doses, or two different combined drugs.]

[Bottlenecks in primary aldosteronism care – focus on screening and biochemical diagnosis]


[ The primary (hyper) aldosteronism (PA) is a spectral disease forming a continuum from normotensive to cases that warrant adrenalectomy. PA definition is laden with inherent uncertainties. The main paradigm shift in the two new recommendations described below is that no change in medication is recommended before PA screening, to help broaden the scope of screenings. Both continue to be based on suppressed renin activity, but the serum aldosterone threshold has been lowered to increase sensitivity. With this algorithm, however, the proportion of positive screenings is significantly increased, creating another bottleneck, leading to congestion of patients referred to a specialist to perform an additional suppression test.]

[The rapidly spreading SARS-CoV2 respiratory virus has evoked an epidemic with serious aftermath around the world. In addition to the health effects, the global economic damage is actually unpredictable. At the same time, the pandemic has launched a series of unprecedented collaborative scientific research, including the development of vaccines. This study summarizes up-to-date information on vaccines, immune memory, and some emerging clinical effects.]

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]


[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

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


[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.
