Results indicated that dietary self-efficacy determined both behaviours and laboratory outcomes. Patients with greater dietary self-efficacy had lower serum potassium and weight gain, showed favourable compliance attitudes and behaviours toward prescribed regimens and fostered better relationships with staff. Based on these findings we recommend an experimental approach to clarify whether maximizing dietary self-efficacy efforts is without psychological burden to patients and whether the positive effect of increased dietary self-efficacy is maintained in long-term dialysis patients.

Target-organ damage develops in a stepwise fashion in adolescent hypertension. An increased intima-media thickness can be demonstrated not only in the sustained but also in the white-coat form of adolescent hypertension.

Use of the EZ-blocker is easy and safe. The short insertion time and short lung deflation time through the lumen of the SLT allows its use in emergency situations or in cases of a difficult airway.

Background Sevoflurane is one of the most frequently used inhaled anesthetics for general anesthesia. Previously it has been reported that at clinically used doses of sevoflurane, cerebral vasoreactivity is maintained. However, there are no data how sevoflurane influences systemic and cerebral circulation in parallel. The aim of our study was to assess systemic and cerebral hemodynamic changes as well as cerebral CO 2 -reactivity during sevoflurane anesthesia. Methods Twenty nine patients undergoing general anesthesia were enrolled. Anesthesia was maintained with 1 MAC sevoflurane in 40% oxygen. Ventilatory settings (respiratory rate and tidal volume) were adjusted to reach and maintain 40, 35 and 30 mmHg EtCO 2 for 5 min respectively. At the end of each period, transcranial Doppler and hemodynamic parameters using applanation tonometry were recorded. Results Systemic mean arterial pressure significantly decreased during anesthetic induction and remained unchanged during the entire study period. Central aortic and peripherial pulse pressure and augmentation index as markers of arterial stiffness significantly increased during the anesthetic induction and remained stable at the time points when target CO 2 levels were reached. Both cerebral autoregulation and cerebral CO 2 -reactivity was maintained at 1 MAC sevoflurane. Discussion Cerebral autoregulation and CO 2 -reactivity is preserved at 1 MAC sevoflurane. Cerebrovascular effects of anesthetic compounds have to be assessed together with systemic circulatory effects.

There is a difference between the severity of hypertension between hypertensive adolescent girls and boys. Hypertensive girls differ from normotensive girls not only in blood pressure values but also in risk factors and subclinical target organ effects. Further studies are needed to explain the gender differences in adolescent hypertension. The potential role of sex hormones in hypertensive teenagers also needs to be clarified in future works.

Background and Purpose: Nitric oxide (NO)/endothelin imbalance may play a role in the regulation of cerebral blood flow. The aim of the present study was to assess whether these endothelial factors influence middle cerebral artery blood flow velocities (MCAV) and cerebrovascular reactivity (CVR) in healthy and hypertensive adolescents. Subjects and Methods: 106 adolescents (61 hypertensive and 45 normotensive) underwent transcranial Doppler measurements of the middle cerebral artery at rest and after 30 s of breath-holding (BH) and 60 s of hyperventilation (HV). Additionally, NO and endothelin-1 (ET-1) concentrations of the serum were assessed. The correlation between NO and ET-1 levels as well as MCAV and CVR values was analyzed. Results: Resting MCAVs were higher among hypertensive teenagers (76.5 ± 24 vs. 62.8 ± 15.6 cm/s, respectively, p < 0.001). CVR values did not differ between hypertensive and healthy adolescents after the BH and HV procedure. A significant negative correlation was found between absolute MCAV values and NO concentrations. ET-1 was positively related to MCAV. Conclusions: Cerebral blood flow velocities, but not CVR values, are associated with serum NO and ET-1 concentrations in adolescents.

A 2019 decemberében kitört koronavírus-fertőzéses világjárványban megbetegedettek ellátása jelentős terhet ró az egészségügyre. Nemcsak azért, mert a betegek egy része intenzív terápiás ellátást igényel, hanem mert a betegség bármely súlyossági formájában szenvedő betegeknek sebészi kezelésre is szükségük lehet. Ennek megoldása pedig jelentős kihívás elé állítja az aneszteziológusokat. Ezen összefoglaló a sebészi kezelést igénylő betegek aneszteziológiai és perioperatív ellátásának gyakorlati aspektusait hivatott bemutatni. Orv Hetil. 2020; 161(17): 692-695.

Aneszteziológiai és Intenzív Terápiás Klinika, DebrecenJelenleg a COVID-19 kezelésére bizonyítottan hatékony terápia nem áll rendelkezésre. Az alábbiakban a teljesség igénye nélkül az ilyen vonatkozásban leginkább vizsgált gyógyszerek kerülnek bemutatásra. A felsorolt terápiás lehetőségek mindegyike kísérletinek tekintendő ebben a fázisban. Tekintettel a járvány súlyos népegészségügyi hatásaira, illetve az intenzív osztályon kezelt COVID-19-betegek potenciálisan fatális kimenetelére, 'off-label' alkalmazásuk mégis megfontolandó.
